Routine diagnostic laparoscopy is unnecessary in staging tumors of the pancreatic head.

BACKGROUND: This study examined the success of computed tomography (CT) and angiography in predicting resectability of tumors of the pancreatic head and retrospectively examined whether diagnostic laparoscopy would have contributed additional staging information. METHODS: The records of 67 patients with tumors of the pancreatic head were reviewed. Thirty-four patients had unresectable tumors, and 33 had tumors that were considered operable according to CT and angiographic findings. RESULTS: Surgical resection was successful in 27 of 33 patients (82%). Surgical resection was abandoned in 6 cases due to inability to develop a plane behind the pancreatic head in 4 cases, peritoneal implants in 1 case, and an occult hepatic metastasis in 1 case. Diagnostic laparoscopy might have detected metastases in the latter two cases. Thus, in retrospect, diagnostic laparoscopy might have altered management in only 2 of 33 surgical cases (7%). CONCLUSIONS: The potentially limited usefulness of diagnostic laparoscopy in this series, in retrospect, raises the question of whether routinely using diagnostic laparoscopy in staging tumors of the pancreatic head is cost effective.

Staging laparoscopy for gastric cancer.

Surgical resection remains the only potentially curative treatment of patients with gastric cancer. Evaluation of surgery and other treatments depends on accurate staging of the disease. The objective of the study was to compare staging laparoscopy with ultrasonography, endoscopic ultrasound, computed tomography, and histology for serosal infiltration, lymph node metastasis, peritoneal seeding, and hepatic metastasis. Diagnostic laparoscopy was carried out in 48 patients. Prelaparoscopic staging in all cases included upper gastrointestinal endoscopy and biopsies followed by endosonography, ultrasound, and computed tomography. Preoperative combined examination using CT and laparoscopy was superior when compared with each modality alone or the combinations of the other tests. The present study showed that preoperative evaluation of patients with laparoscopy is superior to all other diagnostic tests. We also found that laparoscopy and computed tomography were better in accurately assessing the serosal infiltration, peritoneal seeding, and hepatic metastases, which thus allows the surgeon to choose more effective treatment modality.

Is laparoscopy necessary before assisted reproductive technology?

PURPOSE OF REVIEW: Laparoscopy is widely used during infertility work-up, although it is sometimes unnecessary. This review highlights when laparoscopic intervention should be used in women undergoing assisted reproductive technology cycles. RECENT FINDINGS: There is no evidence for an increase in pregnancy rates in assisted reproductive technology cycles following surgical treatment of pelvic adhesions or endometriosis with laparoscopy. If the patient has bilateral visible hydrosalpinges, laparoscopy may be an option for evaluation of the tubes and treatment with salpingectomy in order to enhance the chance of pregnancy before commencing an assisted reproductive technology cycle. Laparoscopic ovarian drilling before assisted reproductive technology may be considered a therapeutic option in polycystic ovary disease patients who previously had severe ovarian hyperstimulation syndrome. Finally, laparoscopy may be useful in replacing the transposed ovaries to their original sites in the pelvic cavity in previously treated cancer patients so that monitoring of the controlled ovarian hyperstimulation and the oocyte aspiration would be much easier during the assisted reproductive technology cycles. SUMMARY: Laparoscopy should be considered before assisted reproductive technology cycles if the procedure diagnoses and treats a pelvic pathology at the same time and if laparoscopic intervention increases the chance of pregnancy following these cycles.

Laparoscopy is sufficient to exclude occult diaphragm injury after penetrating abdominal trauma.

BACKGROUND: Occult diaphragm injury after penetrating thoracoabdominal injury can be difficult to diagnose and can remain occult for months to years. Delayed diagnosis is associated with the risk of hernia formation, strangulation, and high morbidity and mortality. Although laparoscopy has been proposed as a means of evaluating the diaphragm in these patients, prior studies did not include a confirmatory procedure or did not report long-term follow-up. Thus, true sensitivity and specificity remain unknown. The purpose of this study was to determine the sensitivity and specificity of laparoscopy for the detection of diaphragm injury after penetrating thoracoabdominal trauma. We hypothesized that laparoscopy alone is sufficient to exclude diaphragm injury after penetrating thoracoabdominal trauma. METHODS: We conducted a prospective case series of 34 hemodynamically normal asymptomatic patients with thoracoabdominal penetrating injuries. All patients underwent diagnostic laparoscopy to evaluate the diaphragm for the presence of injury. All patients then underwent confirmatory celiotomy (n = 30) or video-assisted thoracoscopy (n = 4). RESULTS: All patients were men between the ages of 18 and 54 years. There were 37 stab wounds and 1 gunshot wound. The mean lowest preoperative systolic blood pressure recorded was 120 +/- 18 mm Hg. Penetrating injuries were stratified by anatomic location (anterior, 18; posterior, 8; flank, 9; not specified, 3). There were 7 true-positive, 30 true-negative, no false-positive, and 1 false-negative result. Specificity, sensitivity, and negative predictive value were 100%, 87.5%, and 96.8%, respectively. The single missed injury occurred in a patient with hemoperitoneum from associated splenic injury that obscured the diaphragm and warranted celiotomy. CONCLUSION: In asymptomatic hemodynamically normal patients with penetrating thoracoabdominal injury, laparoscopy alone is sufficient to exclude diaphragmatic injury.

Comparison of three-dimensional hysterosalpingo-contrast-sonography and diagnostic laparoscopy with chromopertubation in the assessment of tubal patency for the investigation of subfertility.

BACKGROUND: Two-dimensional hysterosalpingo-contrast-sonography, as a screening test for tubal patency for subfertile patients, is limited by the difficulty in visualizing the entire Fallopian tube owing to its tortuosity. This major disadvantage can be overcome by means of the three-dimensional hysterosalpingo-contrast-sonography (3D-HyCoSy). The current study compared the efficacy of 3D-HyCoSy with diagnostic laparoscopy and its feasibility as a screening test for tubal patency. METHODS: Twenty-one consecutive patients scheduled to have laparoscopy were recruited to undergo the 3D-HyCoSy 2 days before the scheduled laparoscopy. Echovist (Schering AG, Berlin, Germany), the ultrasound contrast medium, was injected into the uterine cavity via a Foley's catheter. The flow of the medium in the Fallopian tube was captured by using three-dimensional power Doppler mode and was stored for later analysis. The person analyzing the images, the surgeon performing the laparoscopy, and the patients were blinded to the patients' identity and the sonography findings. The sonography and the laparoscopy findings were compared. The duration for the ultrasound examination, pain score, and patient acceptability were assessed. RESULTS: Thirty-four of 42 (81%) Fallopian tubes were assessed. The sensitivity of 3D-HyCoSy for detecting tubal patency was 100% with a specificity of 67%. The positive and negative predictive values were 89 and 100%, respectively; the concordance rate was 91%. The mean duration (+/- SD) for the 3D-HyCoSy was 13.4 +/- 5.5 min. Fifteen patients (71%) regarded the sonography examination as at least acceptable. CONCLUSIONS: This study confirmed the feasibility of using 3D-HyCoSy as an initial investigation for tubal patency.

Effect of laparoscopy versus laparotomy on circulating tumor cells using isolation by size of epithelial tumor cells.

AIM: To assess the effect of laparoscopy on circulating tumor cell (CTC) detection in case of carcinosis. MATERIAL AND METHODS: We compared laparoscopy versus laparotomy on tumor cell blood release in an animal model of ovarian carcinosis obtained by intraperitoneal inoculation of IGR-OV1 cells in nude rats. Animals were randomly assigned to one of the following groups: CO(2) laparoscopy (L), gasless laparoscopy (GL), midline laparotomy (ML), or general anesthesia as control (C). A 0.5 ml blood sample was taken in each case before and after experiment and tested with a novel assay, ISET (isolation by size of epithelial tumor cells), which isolates CTC by filtration on account of their size. Statistics were performed with the Fisher's and the Chi-square tests. RESULTS: Ten rats were included in each group. We did not find any significant difference in CTC prevalence before and after surgery (2/14 versus 3/19, respectively, P = 1). Similarly, the three surgical accesses were equivalent with one post-experiment detection per group: 1/5 for L, 1/7 for ML, 1/7 for GL, and 1/6 for C (P = 0.9). CONCLUSION: This trial did not show any deleterious effect of laparoscopy on CTC when compared to laparotomy.

Combined diagnostic approach of laparoscopy and hysteroscopy in the evaluation of female infertility: results of 612 patients.

AIM: To clarify the role of a combined diagnostic approach using laparoscopy and hysteroscopy in the evaluation of female infertility in developing countries. METHODS: In a prospective study, 612 consecutive infertile women underwent complete fertility evaluation at a tertiary university infertility clinic: 300 complained of primary infertility, 221 of secondary infertility, and 91 were requesting reversal of a previous tubal ligation. All the patients were examined by simultaneous combined laparoscopy and hysteroscopy as a part of their routine infertility evaluation. Focused hysteroscopic evaluation of the region of utero-tubal junction was attempted. RESULTS: Laparoscopy was successful in 608 and hysteroscopy in 597 patients. The most frequent pathologies detected hysteroscopically in the infertile group were adhesive in nature and believed to be post-traumatic and/or post-phlogistic. The number of intrauterine abnormalities found by hysteroscopy was significantly greater than by hysterosalpingography. The rate of diagnosis of significant lesions by laparoscopy of 64.3% rose to 76.6% when the hysteroscopic findings were included. A significant number of women with secondary infertility had abnormal hysteroscopic findings when compared to either women with primary infertility or those requesting sterilization reversal. Hysteroscopic evaluation of the region of utero-tubal junction revealed significant lesions believed to have caused infertility in comparison with those requesting sterilization reversal. CONCLUSION: The combined diagnostic approach of laparoscopy and hysteroscopy is recommended in the evaluation of female infertility in communities where the risk of pelvic infections is great.

Is laparoscopy associated with a lower rate of postoperative adhesions than laparotomy? A comparative study in the rabbit.

This trial set out to test the hypothesis that there is no difference in the incidence of intra-abdominal adhesions after a stereotyped intraperitoneal injury created via laparoscopy or laparotomy. Twenty New Zealand White rabbits had a 2 x 2 cm area of peritoneum stripped off their caecum and adjacent parietal peritoneum, either by laparotomy or laparoscopy. Outcome was assessed by the incidence of adhesions to the test site and the wound. There was no difference in the rate of adhesions at the test site in the two groups. The rate of adhesions to the wound was different in the two groups (70% laparotomy, 0% laparoscopy; P = 0.003). In a rabbit model, comparing laparoscopy and laparotomy in a strictly controlled operative environment, a stereotyped intraperitoneal injury results in similar rates of postoperative adhesions. Laparoscopy is, however, associated with a much lower incidence of wound adhesion. The potential for postoperative adhesions is real after laparoscopic surgery.

The role of laparoscopy in evaluation of the impalpable undescended testis.

BACKGROUND: The evaluation and management of the impalpable testis remains controversial. The authors' experience with laparoscopy for the treatment of this condition is reported here. METHODS: All children with impalpable testes underwent an examination under anaesthetic and if negative, a laparoscopy was performed to locate the testis. A prospective evaluation was undertaken to determine the success and morbidity of this approach. RESULTS: Thirty-six children (median age 2.5 years) underwent laparoscopy to localize 40 impalpable testes. In 32 patients with unilateral impalpable testis, 10 were intra-abdominal, nine were absent. In 13 patients, the vas and vessels entered the groin, and in 12 of these a small testis remnant was excised and in the other a normal-looking testis was brought down. In four patients with bilateral impalpable testes, one testis was absent, three testes were intra-abdominal and four were small testis remnants in the groin. The average laparoscopy time was 15 min, and 34 of 36 children were operated on as day-stay cases. One child had an omental hernia via a port site. CONCLUSION: Laparoscopy is safe and effective at localizing impalpable testes in children and can be performed as day-stay procedures in the majority of cases.

Diagnostic laparoscopy for chronic right iliac fossa pain: a pilot study.

BACKGROUND: The aim of this study was to determine the value of diagnostic laparoscopy in patients with chronic right iliac fossa pain. METHODS: A retrospective study at Echuca Hospital involving case-note review and telephone questionnaire of patients who had undergone diagnostic laparoscopy for chronic right iliac fossa pain at least 12 months earlier (September 1992 to August 1995) was carried out. RESULTS: Forty-one cases were identified and followed up 12-40 months postoperatively (median 21 months). Eleven cases had positive findings at laparoscopy, of whom eight obtained lasting relief after treatment. Of the remaining 30 patients 17 had a normal-looking appendix removed and 12 were cured; these were younger patients with episodic symptoms and localized signs. Of eight patients who had adhesions divided, four with adhesions beneath old scars obtained relief. Altogether 32 of the 41 patients considered the laparoscopy worthwhile even though in some cases it did not relieve their chronic pain. CONCLUSIONS: Diagnostic laparoscopy is worthwhile for patients with chronic right iliac fossa pain. Concurrent appendicectomy should be considered in young patients with episodic, well-localized symptoms associated with systemic malaise while adhesiolysis may be beneficial for viscero-parietal adhesions beneath abdominal wall scars.

Port-site metastases after open laparoscopy: a study in 173 patients with advanced ovarian carcinoma.

Open laparoscopy was used to diagnose advanced ovarian cancer. Patients with a pelvic mass and an omental cake and/or large-volume ascites were selected for open laparoscopy. One hundred and seventy-three patients with stage III or IV ovarian carcinoma underwent diagnostic open laparoscopy. Seventy-one patients underwent complete excision of port sites at the time of debulking surgery. Thirty (17%) patients developed port-site metastases. However, only 8 (5%) of these port-site metastases were clinically diagnosed, while 22 out of 71 (31%) with complete port-site excision were diagnosed on pathologic examination. There was no significant relationship between the development of port-site metastases and median time to primary chemotherapy or surgery, the presence of ascites, or stage IV disease. All port-site metastases disappeared during primary therapy, and none of the patients developed a second relapse in one of their port sites. We observed a high rate of port-site metastases after laparoscopy in patients with advanced ovarian carcinoma. However, prognosis was not worse in this group of patients. Laparoscopy is a convenient technique to diagnose advanced ovarian carcinoma, to exclude other primary tumors, and to refer patients to a tertiary center.

Management of the impalpable testis: the role of laparoscopy.

PURPOSE: To evaluate the use of laparoscopy in the management of the impalpable testis. DESIGN: A retrospective analysis of the clinical findings, interventions, and outcome in 87 consecutive boys undergoing laparoscopy for 97 impalpable testes. RESULTS: Fifty seven testes were either absent (n = 35) or present as a small remnant (n = 22), which was removed at contemporaneous groin exploration. There were 27 intra-abdominal testes, including four hypoplastic testes, which were removed laparoscopically. The 13 remaining viable testes were located in the groin. Conventional orchidopexy followed laparoscopy for 21 testes, and was successful in 17 cases. Two stage laparoscopically assisted Fowler Stevens orchidopexies were performed for 13 intra-abdominal testes, with eight satisfactory results. Ultrasound evaluation significantly reduced the number of conventional orchidopexies following laparoscopy. IMPLICATIONS: Laparoscopy is a rational and safe approach for precise localisation of the impalpable testis. Laparoscopically assisted two stage orchidopexy is a successful treatment procedure for intra-abdominal testes.

Managing gynaecological emergencies with laparoscopy.

A consecutive series of 49 women (50 procedures), whose conditions were haemodynamically stable, presenting with acute lower abdominal pain, pelvic tenderness, and either a urine concentration of greater than 50 U/l beta human chorionic gonadotrophin or a pelvic mass shown by ultrasonography were treated with operative laparoscopy under video monitoring (videopelviscopy) as an alternative to laparotomy. Ectopic pregnancy, ovarian and non-ovarian cysts, pelvic adhesions, endometriosis, and fibroids were found, for which salpingotomy, salpingectomy and salpingo-oophorectomy, cystectomy, adhesiolysis, thermocoagulation, and myomectomy were carried out by laparoscopy. In one patient pelviscopy was repeated because of persistent tubal pregnancy after the fimbria was expressed. Laparotomies were carried out on three patients because treatment was not possible by laparoscopy and on a further patient two days after adhesiolysis had been attempted. These were the only serious complications. For the 46 cases (45 patients) in which operative laparoscopy was successful the mean stay in hospital was 1.9 days after operation, and this group of patients returned to normal activities and to work after an average of 2.3 and 2.6 weeks respectively. Most gynaecological emergencies that are managed by laparotomy can be treated by laparoscopy and benefit both patients and the health service.

MR imaging in pelvic inflammatory disease: comparison with laparoscopy and US.

PURPOSE: To assess the value of magnetic resonance (MR) imaging in the diagnosis of pelvic inflammatory disease (PID) and to compare MR imaging with transvaginal ultrasonography (US) and laparoscopy. MATERIALS AND METHODS: Thirty consecutive patients hospitalized because they were clinically suspected of having PID underwent transvaginal US and T1-weighted spin-echo, T2-weighted turbo spin-echo, and inversion-recovery MR imaging at 1.5 T. All patients underwent laparoscopy after MR imaging. RESULTS: PID was laparoscopically proved in 21 (70%) patients. The MR imaging diagnosis agreed with that obtained with laparoscopy in 20 (95%) of the 21 patients with PID. The imaging findings for PID were as follows: fluid-filled tube, pyosalpinx, tubo-ovarian abscess, or polycystic-like ovaries and free pelvic fluid. Findings at transvaginal US agreed with those at laparoscopy in 17 (81%) of the 21 patients with PID. The sensitivity of MR imaging in the diagnosis of PID was 95%, the specificity was 89%, and the overall accuracy was 93%. For transvaginal US, the corresponding values were 81%, 78%, and 80%. CONCLUSION: MR imaging is more accurate than transvaginal US in the diagnosis of PID and provides information about the differential diagnosis of PID. MR imaging may reduce the need for diagnostic laparoscopy.

Dual effect of laparoscopy on cell-mediated immunity.

Laparoscopic influence on cell-mediated immunity and tumour evolution is controversial. The objective of the present study was to assess tumour growth and immune patterns after laparoscopy on an experimental study. Lewis rats, bearing an intrapancreatic ductal carcinoma randomly underwent one of the following 2-hour procedures: anaesthesia, laparotomy or CO(2) pneumoperitoneum. Cell-mediated immunity was investigated through determination of serum IL1beta concentrations by ELISA and TNFalpha, IL6 and iNOS gene transcriptions in blood white cells and peritoneal cells by RT-PCR 1 day after operation. Tumour growth and spread patterns were assessed on anatomopathological examination 2 weeks after surgery. Tumour growth and spread were unaffected no matter what procedure was applied, but port-site seeding occurred in half of the cases undergoing laparoscopy. No significant change in acute-phase protein response, represented by IL1beta serum concentration, was found after laparoscopy. TNFalpha, IL6 and inducible NO synthase gene transcriptions were enhanced in blood white cells and depressed in peritoneal immune cells after laparoscopy. In our experimental conditions, cell-mediated immune response to CO(2) pneumoperitoneum seems to be a good systemic immune activation and a less acute peritoneal immune response as opposed to control laparoscopy. This early impairment of peritoneal macrophage immune activity, observed after a long-lasting CO(2) pneumoperitoneum, might be responsible for the high rate of port site recurrence.

Staging laparoscopy and its indications in pancreatic cancer patients.

BACKGROUND: Laparoscopy has become a popular and widespread surgical technique. An important goal in the treatment of patients with pancreatic cancer is to avoid any unnecessary procedure. Laparoscopy has been suggested as a routine tool for staging in order to prevent unnecessary laparotomies in these patients. METHODS: In this article we present our experience regarding the value of laparoscopic staging and review the literature on this topic. RESULTS AND CONCLUSION: A direct and conclusive comparison of the controversial literature is difficult because of different study designs. Inconsistent use of high-quality CT scans significantly affects the results. However, recent studies reveal that not more than 14% of the patients benefit from diagnostic laparoscopy when a state-of-the-art CT scan has been performed previously. Therefore, we conclude that routine diagnostic laparoscopy is not justified in all patients with pancreatic cancer. Rather, selective use is appropriate, especially in patients in whom ascites is an indirect sign of peritoneal metastases, or if liver metastases cannot be surely excluded preoperatively. This approach is cost-effective and limits diagnostic laparoscopy to a subgroup of patients in whom a laparotomy can be avoided.

Serum CA19-9 measurement increases the effectiveness of staging laparoscopy in patients with suspected pancreatic malignancy.

BACKGROUND/AIMS: Staging laparoscopy for suspected pancreatic neoplasia is not widely accepted due to its low yield. The aim of this study was to determine if serum carbohydrate antigen (CA19-9) levels could be used to improve the selection of patients for staging laparoscopy. METHODS: The data from a prospectively collected database (1997-2004) with 159 patients who had computed tomography-predicted resectable disease and who had undergone laparoscopic staging were analysed to determine if a low preoperative CA19-9 level (< or =150 kU/l, or < or =300 kU/l with a bilirubin >35 micromol/l) identified patients in whom laparoscopy was not useful. RESULTS: The CA19-9 level was >150 kU/l in 96 patients of whom 75 (78%) were considered resectable following laparoscopic assessment. There were 63 patients with a CA19-9 < or =150 kU/l of whom 60 (95%) were considered resectable following laparoscopic assessment. The sensitivity, specificity, positive predictive value and negative predictive value for CA19-9 < or =150 kU/l in predicting that laparoscopic assessment would judge patients as resectable were 44, 88, 95 and 22%, respectively. A cut-off level of < or =300 kU/l in patients with a bilirubin >35 micromol/l produced values of 30, 94, 94 and 28%, respectively. By using CA19-9 < or =150 kU/l, laparoscopy could have been avoided in 40% of patients, increased to 55% of patients with adjustment for the presence of jaundice; concomitantly, the yield from laparoscopy would have been increased from 15 to 22 and 25%, respectively. CONCLUSION: Use of serum CA19-9 levels would increase the efficiency of laparoscopic staging in patients with suspected pancreatic malignancy.

Laparoscopy for colorectal cancer.

The advantages of laparoscopy in the treatment of benign disease have been well demonstrated. Compared to open surgery, laparoscopy is associated with a shorter hospital stay, less ileus, decreased postoperative pain, earlier return to work, and better cosmesis. The role of laparoscopy for the cure of malignant disease, however, remains controversial. In order to elucidate the safety and efficacy of laparoscopy for malignancy, worldwide large controlled randomized trials were developed. While awaiting the results of large randomized trials, a review of the many published studies to date was undertaken demonstrating a high level of evidence of the superiority of laparoscopy over laparotomy in regard to short-term benefits, when performed by appropriately skilled surgeons in properly selected patients. The data also suggest similar or superior local recurrence and long-term survival rates. However, further follow-up and review of large, multicenter, randomized trials will be needed before widespread acceptance of the technique can be recommended.
