Tumor seeding following laparoscopy: international survey.

The aim of the study was to determine if tumor seeding during laparoscopic surgery for cancer is a rare event or a typical complication of this procedure. Laparoscopic staging and treatment of intraabdominal tumors is increasing in gastroenterology, gynecology, and general surgery. A total of 1052 questionnaires were mailed to surgical department chairmen, members of the German Society of Surgery, Swiss Association for Laparoscopic and Thoracoscopic Surgery, and Austrian Society of Minimal Invasive Surgery asking them to list their department's experience with tumor seeding after laparoscopy for nonapparent or known malignancy. There were 607 (57.7%) surgeons who reported a total of 117,840 laparoscopic cholecystectomies, 409 incidental gallbladder carcinomas, and 412 laparoscopies on patients with colorectal carcinoma. Altogether 109 patients who developed tumor recurrence in connection with laparoscopic surgery have been reported. Port-site recurrence was identified in 70 of 409 patients (17.1%) with a median of 180 days following laparoscopic cholecystectomy for nonapparent gallbladder carcinoma. In 8 cases (11.5%) a protective plastic bag had been used for gallbladder retrieval. Six patients without port-site metastases were found to have a diffuse peritoneal carcinomatosis a median of 120 days after cholecystectomy. Of 412 laparoscopies for colorectal cancer, 19 cases (4.6%) of tumor seeding have been reported, 16 of which (3.9%) had documented port-site and scar recurrences a median of 196 days after laparoscopy. The tumor specimen was intact, and a plastic bag was used for extraction in seven cases. In 14 patients trocar-site metastases have been reported a median of 70 days after laparoscopy for different nonapparent or known malignancies. The probability of developing abdominal wall metastasis is higher after laparoscopy for cancer than after open surgery. An intact surgical specimen and the use of a plastic retrieval bag do not exclude the risk of port-site recurrences. These facts and the early appearance of peritoneal carcinosis in a few cases of intraabdominal malignancies seem to confirm a specific laparoscopic risk for intraperitoneal tumor cell seeding and implantation.

Therapeutic laparoscopy for abdominal trauma.

BACKGROUND: Instead of open laparotomy, laparoscopy can be used safely and effectively for the diagnosis and treatment of traumatic abdominal injuries. METHODS: Between February 1998 and January 2002, 78 hemodynamically stable patients (49 males and 29 females) with suspicious abdominal injuries underwent diagnostic or therapeutic laparoscopy. The patients ranged in age from 15 to 79 years (median, 40.9 years). Of these patients, 52 were evaluated for blunt trauma and 26 had sustained a stab wound. Preoperative evaluation with enhanced abdominal computed tomography (CT) showed some significant injuries in all cases. All of the laparoscopic procedures were performed in the operating room with the patient under general anesthesia. Pneumoperitoneum was established using an open Hasson technique at the umbilicus, and a forward-viewing laparoscope (30 degrees) was inserted. Two additional 5- or 10- and 12-mm trocars were placed in the right and left lateral quadrants for manipulation, retraction, aspiration-irrigation, coagulation, and the like. The abdominal cavity was systemically examined, the hemoperitoneum aspirated, and the lesion causing the bleeding or spillage located. RESULTS: On the basis of the laparoscopic findings, diagnostic laparoscopy was enough for 13 patients, and therapeutic laparoscopy was performed in 65 patients (83%) for gastric wall repair [8], small bowel repair [15], small bowel resection-anastomosis [19], ligation of bleeders in the mesentery and omentum [8], sigmoid colon repair [4], Hartmann's procedure [5] cholecystectomy [2], distal pancreatectomy [2], and splenectomy [2]. Totally laparoscopic procedures were performed in 43 patients, laparoscopically assisted procedures in 20 patients, and hand-assisted laparoscopic surgery in 2 patients. No significant abdominal injuries were missed as a result of laparoscopy, and no conversion to exploratory laparotomy was noted. The mean operation time was 142 min, and the mean hospital stay was 9.8 days. There were three cases of postoperative complications (1 wound infection, 1 paralytic ileus, and 1 atelectasis), but no missed injuries and no mortality. CONCLUSIONS: The short-term results from this study suggest that laparoscopy is a safe, feasible, effective procedure for the evaluation and treatment of hemodynamically stable patients with abdominal trauma, and that it can reduce the number of nontherapeutic laparotomies performed.

Role of laparoscopy in vaginal malformation.

BACKGROUND: The aim of this study was to assess the role of laparoscopy in the management of vaginal malformations in children, a subject not often discussed in the literature. METHODS: Between 1980 and 2002, we treated 22 children for vaginal malformations. Two main patient populations were distinguished: younger children with asymptomatic hymenal imperforation and hydrocolpos, and adolescents with hematocolpos. A third of the malformations were identified on systematic clinic examination, a third on the basis of abdominal pain, and a third due to various other symptoms. Nine of the girls had associated malformations of the uterus, external genital organs, or urinary tract. Eight patients underwent laparoscopy, either to look for endometriosis in cases of hematocolpos, to make an accurate determination of malformations in cases where clinical and paraclinical methods failed, or to manage an abnormality. RESULTS: Eleven laparoscopic procedures were performed in eight patients. Three diagnostic laparoscopies enabled us to determine the exact nature of the malformations. One newborn underwent two laparoscopic procedures to treat peritoneal fibrous bands that had caused repeated episodes of obstruction. Six patients underwent exploratory laparoscopy to look for endometriosis, but none was found. CONCLUSION: Laparoscopy is not applied systematically in the management of any malformation, but it can be useful when complementary exams fail to make an accurate diagnosis of the anomaly or for the management of the rare complication of adhesions and bands. When used to search for endometriosis, MRI detects ~50% of lesions, but laparoscopy is certainly still appropriate for that purpose. However, the optimal timing of the procedure still needs to be established.

Laparoscopy alone is superior to peritoneal cytology in staging gastric and esophageal carcinoma.

BACKGROUND: Laparoscopy identifies metastatic disease in patients with upper gastrointestinal malignancies; however, it has been suggested that cytological examination of peritoneal washings may increase the diagnostic yield. We hypothesize that the addition of cytologic washings to a standardized staging laparoscopy is unnecessary for the identification of intraabdominal metastasis in patients with gastric/esophageal cancer. METHODS: Forty patients with gastric/esophageal cancer were prospectively evaluated. Patients successfully underwent a diagnostic laparoscopy protocol (with biopsies) during which peritoneal washings were obtained and processed for cytologic analysis. Laparoscopic versus cytologic identification of intraabdominal metastasis were compared. RESULTS: Forty patients successfully completed laparoscopy with collection of peritoneal washings. Laparoscopic examination of the peritoneal cavity upstaged 21 (52.5%) patients. Laparoscopic examination consistently identified a statistically significant higher number of positive patients than cytologic examination of peritoneal washings (p = 0.001) and examination of cytologic washings alone failed to identify 45% of patients with positive findings and laparoscopy. The addition of cytologic examination added no additional stage IV patients to the laparoscopy-negative group. CONCLUSION: A standardized laparoscopic examination alone is sufficient for the identification of intraabdominal metastatic disease in patients with gastric and esophageal cancer.

Influence of different gases used for laparoscopy (helium, carbon dioxide, room air, and xenon) on tumor volume, histomorphology, and leukocyte-tumor-endothelium interaction in intravital microscopy.

BACKGROUND: Previous studies indicate that helium pneumoperitoneum used for laparoscopic surgery suppresses whereas carbon dioxide pneumoperitoneum increases postoperative tumor growth. The pathomechanisms of decreased tumor growth by helium are unknown. This study was designed to examine the effect of the gases helium, carbon dioxide (CO(2)), and air, and xenon, which can be used to induce pneumoperitoneum in laparoscopy on tumor volume, histomorphology, and leukocyte-endothelium interaction measured by intravital microscopy in rats with implanted liver malignoma (Morris hepatoma 3924A). METHODS: In 46 rats, Morris hepatoma 3294A cells were implanted intrahepatically. After implantation, rats were randomized into two main groups. In the first main group, 10 animals were prepared for examination of leukocyte-endothelium interaction by intravital video microscopy and were randomized into two groups. Five days after implantation they underwent laparoscopy using either helium (n = 5) or CO(2) (n = 5). Ten days after implantation the rats underwent intravital video microscopy to assess leukocyte-endothelium interaction in the tumor and liver vessels. In the second main group 36 rats were prepared for examination of tumor volume arid histomorphology. They were randomized into five groups. Five days after implantation they underwent laparoscopy using helium (n = 7), carbon dioxide (n = 7), room air (n = 7), or xenon (n = 8). The control group (n = 7) received anesthesia only. Rats were killed 10 days after tumor implantation to assess tumor volume and histomorphology. RESULTS: Compared to the control group or groups that received CO(2), room air, or xenon for pneumoperitoneum, the establishment of helium pneumoperitoneum caused a significantly smaller tumor volume (Kruskal-Wallis test, p = 0.001; median tumor-volume: control group, 44 mm(3); helium 19 mm(3)). There was no significant difference in histomorphology between the groups. There was only a statistically significant difference in the development of central tumor necrosis in accordance to tumor volume (Mann-Whitney test, p = 0.03). In the tumor samples, roller counts were statistically significantly higher in the helium group compared to the CO(2) group (p = 0.04). For sticker counts, no statistically significant effects due to liver/tumor (p = 0.13) or treatment (p = 0.48) were observed. CONCLUSIONS: There was a significant decrease in tumor volume using helium pneumoperitoneum for laparoscopy compared to the other gases. Here, we demonstrate that suppression of tumor growth is not due to variation of histomorphology. It seems that helium pneumoperitoneum effects a higher leukocyte-endothelium interaction and thereby a higher immune activation. This could be one explanation for the statistically significantly smaller tumor volume after laparoscopy with helium compared to laparoscopy with CO(2).

Early laparoscopy as a routine procedure in the management of acute abdominal pain: a review of 1,320 patients.

BACKGROUND: Acute abdominal pain is a common cause for presentation to the emergency room and hospital admission. Many of these patients will undergo exploration for suspected appendicitis, but in 20-35% of cases a normal appendix is found. Because of the limited access provided by the gridiron incision, a definitive diagnosis may not be found. Other patients may be treated conservatively and discharged, only to return with recurrent pain or more definitive symptoms of pathology. In patients with acute abdominal pain, early laparoscopy is an accurate means of both making a definitive diagnosis and avoiding a delay in the diagnosis. METHODS: We performed a retrospective analysis of 1,320 consecutive patients with acute abdominal pain over a 62-month period. All patients underwent diagnostic laparoscopy within 48 h of admission. We evaluated the initial clinical diagnosis, the laparoscopic diagnosis, and the subsequent outcome in this group of patients. Individuals with abdominal trauma were excluded from the study, and all patients were >12 years of age. RESULTS: A definitive diagnosis was made in 90% of patients after diagnostic laparoscopy. Laparoscopy changed the clinical diagnosis in 30% of cases. (83%) of patients underwent a laparoscopic operation for management of their condition at the time of diagnosis. In 92 patients (7%), conversion to laparotomy was required to manage their condition. Peritonitis was present in 180 patients; of 110 of them had appendicitis. Twelve patients developed complications related to the diagnostic laparoscopy or the laparoscopic operation, and there was one postoperative death due to a perforated gastric malignancy. Mean operating time was 30 min (range, 17-90). CONCLUSION: Early diagnostic laparoscopy and treatment results in the accurate, prompt, and efficient management of acute abdominal pain. This technique reduces the rate of unnecessary laparotomy and right iliac fossa gridiron incisions and increases the diagnostic accuracy in these patients. This treatment method is feasible where facilities are available to accommodate the workload and there are practitioners with the requisite expertise.

Performance of laparoscopy in identifying malignant ovarian cysts.

BACKGROUND: Peroperative identification of malignancy is crucial to management planning for ovarian cysts. The aim of this study was to evaluate the performance of laparoscopy in identifying malignant ovarian cysts. METHODS: Patients undergoing laparoscopy for ovarian cysts from 1998 to 2001 were enrolled prospectively. Physical findings, Doppler ultrasonography, and serum CA 125 served to compute two risk-of-malignancy indexes (RMI-1 and RMI-2), and laparoscopy findings served to categorize lesions as benign, possibly malignant, or malignant. Frozen sections were examined as needed. Final histology was the reference. RESULTS: Of 313 patients, 294 had benign cysts, six borderline lesions, and 13 malignancies. Sensitivity and specificity were respectively 84 and 93% for RMI-1, 92 and 80% for RMI-2, 100 and 99% for laparoscopy, 91 and 100% for frozen sections, and 100 and 100% for laparoscopy plus frozen sections, which had 100% negative predictive value. Six (1.8%) adverse events occurred. CONCLUSIONS: Laparoscopy reliably identifies ovarian cancer and borderline disease. Morbidity is low compared to oncologic surgery.

Impact of diagnostic laparoscopy on the management of chronic pelvic pain.

BACKGROUND: Diagnostic laparoscopy is a useful tool, especially when there is no definite anatomical abnormality visible on imaging modalities. We assess the role and clinical impact of diagnostic laparoscopy in the management of women with chronic pelvic pain. METHODS: Clinical data of 3,068 cases of diagnostic laparoscopy performed for chronic pelvic pain from June 1994 to August 2005 were analyzed. We compared the diagnoses after diagnostic laparoscopy and those after pelvic examination and imaging modalities such as ultrasound or computed tomography (CT), and we then checked the final pathologic diagnoses after operation. RESULTS: Pelvic endometriosis was the most common (60.2%) laparoscopic finding in patients with chronic pelvic pain in this study, followed by normal pelvic findings (21.2%) and pelvic congestion (13.0%). Diagnostic laparoscopy had an influence on correcting previous plans based on imaging modalities in 42.7% of patients such as discarding unnecessary procedures or introducing new diagnostic or therapeutic plans. There were 3 cases of major complications requiring immediate correction. CONCLUSIONS: Diagnostic laparoscopy is a useful diagnostic tool for of women with chronic pelvic pain and can be used as a guideline for individualized treatment.

Assessment of pancreatic malignancy with laparoscopy and intraoperative ultrasound.

BACKGROUND: Staging laparoscopy for pancreatic malignancy is controversial. This study aimed to assess the efficacy of laparoscopy with intraoperative ultrasound in the management of patients with pancreatic carcinoma. METHODS: The study involved patients undergoing laparoscopy and intraoperative ultrasound over a period of 42 months. The entry criteria specified radiologic (computed tomography) diagnosis of pancreatic carcinoma and no evidence of metastases. RESULTS: The study enrolled 100 patients (52 men and 48 women) ages 21 to 83 years (mean, 63 years). On the basis of imaging, 75 patients had lesions judged to be operable, and 25 patients had a pancreatic head lesion larger than 4 cm radiologically, considered to be unresectable, but with no evidence of metastatic disease. At laparoscopy, three patients had a normal examination, with no evidence of a pancreatic mass, and an additional seven patients had other pathology including one lymphoma, one ampullary tumor, two cases of chronic pancreatitis, and three sarcomas. Of the patients with radiologically inoperable disease, 16% had previously undetected metastases, but 24% were judged to be suitable for curative resection. Half of these patients underwent successful resection. Of the patients with radiologically operable disease, undetected liver or peritoneal metastases were found in 20% of the body or tail lesions and in 26% of the pancreatic head lesions. Of the pancreatic head tumors, 12% were found to be larger than 4 cm and therefore unsuitable for curative resection. Consequently, only 53% were confirmed to be suitable for resection. Of the patients explored with a view to curative resection, 42% actually underwent resection, with clearance of resection margins achieved in 77.8%. CONCLUSION: Of the patients thought to have a resectable tumor on the basis of good quality preoperative imaging, 44% had their management approach altered after laparoscopy and avoided an open procedure. Laparoscopy should therefore be used in the preoperative staging of pancreatic tumors.

Effect of pressure and gas type on intraabdominal, subcutaneous, and blood pH in laparoscopy.

BACKGROUND: According to the literature, the number of port-site metastases in laparoscopic surgery varies considerably depending on the type of gas used for the pneumoperitoneum. In order to investigate this observation we studied the changes in blood, subcutaneous, and intra-abdominal pH during laparoscopy with helium, CO(2) and room air in a rat model. In addition, we looked at the influence of intra-abdominal pressure and duration of pneumoperitoneum on the pH during the laparoscopy. METHODS: pH was measured by tonometry, intra-abdominally and subcutaneously. A pH electrode was additionally placed into the subcutaneous tissue and the results compared to those measured by tonometry. Blood samples were taken from a catheter in the carotid artery. The intra-abdominal pressure was 0, 3, 6, 9 mm Hg for 30 min in each case. We investigated the effect of pneumoperitoneum with CO(2), helium and air in randomized groups of 5 rats. In an additional series the pressure was held constant at 3 mm Hg and the pH was measured every 30 min. RESULTS: Due to the different absorption capacity of the peritoneum, laparoscopy with CO(2) decreases the subcutaneous pH from 7.35 to 6.81. Blood pH is reduced from 7.37 to 7.17 and the intra-abdominal pH from 7.35 to 6.24. Other, less absorbable gases induce smaller changes of blood and subcutaneous pH (only 10% of CO(2)). In a variance analysis the p value is less than 0.001. The influence of duration of laparoscopy (30 min vs. 90 min) on the subcutaneous pH is less compared to the influence of intra-abdominal pressure (0, 3, 6, 9 mm Hg). CONCLUSIONS: Depending on the type of gas (CO(2), air, helium) used for laparoscopy blood, subcutaneous and intra-abdominal pH are influenced differently. Because lower pH is known to impair local defense mechanisms, these results may be one explanation for the higher incidence of port-site metastasis in laparoscopy with CO(2) than with other gases, as reported in the literature.

Does laparoscopy increase bacteremia and endotoxemia in a peritonitis model?

BACKGROUND: Laparoscopy is increasingly used in patients with intraabdominal bacterial infection although pneumoperitoneum may increase bacteremia by elevated intraabdominal pressure. METHODS: The influence of laparotomy and laparoscopy on bacteremia, endotoxemia, and postoperative abscess formation was investigated in a rat model. Rats received intraperitoneally a standardized fecal inoculum and underwent laparotomy (n = 20), or laparoscopy (n = 20), or no further manipulation in the control group (n = 20). RESULTS: Bacteremia and endotoxemia were higher after laparotomy and laparoscopy compared to the control group (p = 0.01) 1 h after intervention. One hour after intervention, aerobic and anaerobic bacterial species were detected in the laparotomy group while only anaerobic bacteria were found in the other two groups. Although bacteremia and endotoxemia did not differ among the three groups after 1 week, the mean number of intraperitoneal abscesses was significantly higher (p < 0.05) after laparotomy (n = 10) compared with laparoscopy (n = 6) and control group (n = 5). CONCLUSION: Laparoscopy does not increase bacteremia and intraperitoneal abscess formation compared to laparotomy in an animal model of peritonitis.

Laparoscopy in the diagnosis of blunt and penetrating injuries to the abdomen.

Laparoscopy was evaluated in thirty-seven patients from a group of 132 consecutive patients who were treated for blunt or penetrating injury to the abdomen. A total of twenty-three patients underwent laparoscopy and laparotomy. The findings at laparotomy correlated with laparoscopy. Fourteen patients underwent laparoscopy only, and there were no proved false-negative results. Of the 132 patients considered for laparotomy, 118 underwent abdominal exploration. Laparotomy was considered unnecessary in twenty-five of the 118 patients (21 per cent) and in retrospect, laparoscopy could have identified in each patient the presence of a minor injury or no injury at all. Laparoscopy is a useful method for evaluating blunt and penetrating injuries to the abdomen in selected patients.

The value of laparoscopy in women with chronic pelvic pain and a "normal pelvis".

During the period January 1976--December 1982 laparoscopy was performed on 186 women complaining of pelvic pain of at least 6 months' duration. In all these cases, the routine pelvic examination and other medical and laboratory tests were negative. Laparoscopy revealed pelvic pathology in only 8.2%: in the vast majority (91.8%) entirely normal pelvic organs were seen. Evidence from the literature is compiling as to the psychogenic origin of most cases of chronic pelvic pain. Recently, it has been shown that laparoscopically negative pelvic pain can be relieved or abolished by psychological intervention. Since pathological findings on laparoscopy are of very low percentage and since the pain is psychogenic in most cases, the value of routine laparoscopy in chronic pelvic pain is very low. We propose that all women with chronic pelvic pain and normal pelvic examination should undergo psychological assessment and treatment if necessary. Laparoscopy should then be reserved for only those cases who show no amelioration on psychological intervention. Our estimation is that this approach would reduce the rate of laparoscopies performed for chronic pelvic pain by about 90%.

Should laparoscopy be a mandatory component of the infertility evaluation in infertile women with normal hysterosalpingogram or suspected unilateral distal tubal pathology?

OBJECTIVE: To assess the diagnostic benefit of laparoscopy in infertile women with normal hysterosalpingography (HSG) or suspected unilateral pathology on HSG. STUDY DESIGN: Charts of infertile women that underwent complete infertility evaluation between 1996 and 1998 were retrospectively reviewed. Eighty-six patients in whom both HSG and laparoscopy were performed were included in the study. HSG results were compared with laparoscopic findings and the suggested treatment based on HSG results was compared with the treatment plan based on laparoscopic findings. RESULTS: Among 63 patients with a normal HSG or suspected unilateral tubal pathology, who were assigned to ovulation induction and intrauterine insemination (IUI), 60 patients were found to have laparoscopic findings that did not necessitate any change in the original treatment plan. In three patients (4.8%), abnormalities discovered at laparoscopy were of such an extent that a change in the original treatment regimen and referral to in vitro fertilization (IVF) was needed. Among 23 patients with suspected bilateral tubal occlusion on HSG, 16 patients (69.6%) were found to have an abnormal laparoscopy with bilateral tubal adhesions, 6 patients (26%) had unilateral tubal adhesions, and 1 patient (4.3%) had pelvic adhesions with no obstruction. These latter findings led to changes in the original treatment plan of these seven patients from IVF to ovulation induction and IUI. CONCLUSIONS: Laparoscopy may be omitted in women with normal HSG or suspected unilateral distal tubal pathology on HSG, since it was not shown to change the original treatment plan indicated by HSG in 95% of the patients. However, laparoscopy should be recommended in cases with suspected bilateral tubal occlusion on HSG, since it altered the original treatment plan in 30% of the patients from IVF to induction of ovulation with IUI. The reassuring results found in the present study may be related to the low prevalence of pelvic inflammatory diseases and endometriosis in our population.

Chronic pelvic pain and quality of life after laparoscopy.

OBJECTIVES: To examine the long-term relationship between chronic pelvic pain (CPP) and quality of life and see if this is affected by a negative laparoscopy result. STUDY DESIGN: A postal questionnaire survey of CPP and quality of life in 63 women who underwent a diagnostic laparoscopy 12-18 months previously. RESULTS: Women with CPP still reported pain 12-18 months after laparoscopy and a significantly poorer quality of life than UK norms for women of a similar age. Factor analysis showed that reports of pain symptoms clustered into two dimensions: (1) pain associated with menstruation and (2) pain associated with sexual intercourse and bladder and bowel function. Most dimensions of quality of life were significantly associated with pain. However, 'role limitation due to emotional problems' and 'mental health' were only associated with pain due to sexual intercourse and bladder and bowel function. Pain and quality of life were not affected by laparoscopy result or follow-up appointment. CONCLUSIONS: Women with CPP continue to have pain and a low quality of life 12-18 months after laparoscopy. Laparoscopy results and follow-up appointments do not appear to affect either pain symptoms or quality of life in the long term, although this may be confounded by women obtaining treatment elsewhere.

Laparoscopy assists surgical decision making in infants with necrotizing enterocolitis.

BACKGROUND: Lack of specific indications for surgical intervention is not uncommon in critically ill infants with necrotizing enterocolitis (NEC). The authors hypothesized that knowledge of the extent of intestinal disease would assist in deciding the operative treatment of choice. The authors report that initial experience with laparoscopy in infants with NEC. METHODS: Prospective evaluation was done of 11 infants with a clinical diagnosis of NEC who were deteriorating despite maximal medical therapy. All underwent laparoscopy on the intensive care unit (ICU). RESULTS: Median gestational age at birth was 29 weeks (range, 24 to 34) and median weight at the time of laparoscopy was 1.2 kg (range, 0.6 to 2.9). Laparoscopy was tolerated well in all cases. NEC was excluded because of the normal intestinal appearance in 2 infants and confirmed in the remaining 9. Urgent laparotomy was avoided in 8 infants, in one of whom a laparoscopically guided ileostomy was performed. In 5 infants, a Penrose drain was inserted at laparoscopy; 3 of these did not require further surgery, and the remaining 2 underwent delayed laparotomy. Three infants, all with intestinal gangrene, died. CONCLUSIONS: Laparoscopy performed in the ICU can provide information regarding intestinal viability which can guide further surgical management. It is feasible and tolerated well even in critically ill neonates less than 1,000 g.

Role of laparoscopy to assess the chance of optimal cytoreductive surgery in advanced ovarian cancer: a pilot study.

OBJECTIVE: To investigate whether laparoscopy can be considered as adequate and reliable as standard laparotomy in predicting optimal cytoreduction (RT < or = 1 cm) in patients with advanced ovarian cancer. METHODS: From March to November 2003, 95 patients with suspected advanced ovarian or peritoneal cancer have been evaluated. Thirty-one cases were excluded due to an anesthesiological class of risk ASA III-IV (51.6%) and for the presence of a large size mass reaching the xiphoid (48.4%). Sixty-four patients completed the study. All patients were submitted to preoperative clinico-radiological evaluation and then to both laparoscopy and standard longitudinal laparotomy, sequentially. Some specific preoperatively defined parameters were analyzed during each procedure in order to obtain the most accurate evaluation on the possibility to get an optimal cytoreduction. RESULTS: The overall accuracy rate of laparoscopy in assessing optimal cytoreduction was 90%. The negative predictive value (NPV) of the clinical-radiologic evaluation corresponded to 73%, whereas in no case was the judgment of unresectable disease obtained by laparoscopy changed by the laparotomic approach (NPV 100%). On the contrary, an optimal debulking was achievable in 34 of 39 cases (87%) selected as completely resectable by explorative laparoscopy. CONCLUSIONS: Laparoscopy can be considered super imposable to standard longitudinal laparotomy in identifying not optimally resectable advanced ovarian cancer patients.

Therapeutic laparoscopy in trauma.

PURPOSE: To assess the therapeutic potential of emergent laparoscopy in the trauma setting, a retrospective review was performed in a busy urban trauma center. PATIENTS AND METHODS: Between December 1991 and October 1993, 133 hemodynamically stable patients with suspected abdominal injury were evaluated laparoscopically. All laparoscopic procedures were performed in the operating room under general anesthesia. Mechanism of injury was stab wound (58), gunshot wound (57), and blunt trauma (18). No significant injuries were found in 72 patients (54%), and these patients received no further treatment. On the basis of laparoscopic findings, 52 patients underwent formal exploratory laparotomy. Surgical exploration confirmed the presence of significant injuries in 44 of the 52 patients (85%). Therapeutic laparoscopy was performed in 6 patients (5%) for diaphragm repair (4), gastrotomy repair (1), and splenorrhaphy (1). Additionally, 10 patients underwent laparoscopy-guided blood salvage for autotransfusion during laparoscopic evaluation of blunt trauma. Three small-bowel enterotomies were repaired during minilaparotomy. RESULTS: No significant injuries were missed as a result of our use of laparoscopy in trauma assessment. Complications--trocar enterotomy, trocar laceration of the inferior epigastric artery, and transient hypotension--occurred in 3 patients secondary to the use of laparoscopy. CONCLUSIONS: Trauma laparoscopy is a safe method for the evaluation of selected patients with abdominal trauma and can reduce the number of negative and nontherapeutic trauma laparotomies performed. Limited therapeutic intervention is possible in a small number of patients.
