Intraperitoneal treatment of incisional and umbilical hernias using an innovative composite mesh: four-year results of a prospective multicenter clinical trial.

Intraperitoneal positioning of conventional parietal mesh provides efficient reconstruction but causes visceral adhesion formation in 80-100% of the cases. The purpose of this clinical trial was to assess the performance and tolerance of a new generation of polyester mesh protected by a hydrophilic resorbable film. Eighty patients were included in a prospective multicenter clinical trial. Patients were treated for ventral hernia via an open approach (64%) or laparoscopically (36%). All meshes were implanted in a midline intraperitoneal location. The main objective was to evaluate the anti-adhesive capability of the mesh in relation to the viscera. In order to assess the absence of visceral adhesion objectively, an ultrasound (US) specific examination was initially validated (pre-operative prediction vs. per-operative findings) and then used during the follow-up. The usual clinical parameters were also collected to follow the patients on a period up to 4 years. Pre-operative US prediction vs. per-operative macroscopic findings: sensitivity 79%, overall accuracy 76%, negative predictive value 85%. After 12 months, 86% of the patients were ultrasonically adhesion free. Early post-operative complications were: seroma/hematoma (16%), subcutaneous infection (4%), cutaneous necrosis (1%) and occlusions (outside the mesh) (2.5%). No mortality was reported. Clinically, after 12-month follow-up, no complication related to post-operative adhesions to the mesh was noted: (occlusion 0%, fistula 0%). Late complications were: mesh sepsis (1%), new defects (4%) and recurrence (2.5%). Finally, 56 patients (75.7%) were clinically evaluated with a mean follow-up of 48+/-6 months. One direct recurrence was noted while six patients experienced new defect outside the mesh. No long-term severe complication such as occlusion or enterocutaneous fistula was observed. Based on a mean clinical follow-up of 4 years, the results of this prospective multicenter clinical trial demonstrate the safety and the efficiency of this composite mesh in the intraperitoneal treatment of incisional and umbilical hernia. In particular there was no early or long-term main complication due to the intraperitoneal location of the mesh.

[Carcinoid tumor from the small bowel].

Carcinoid tumors are non-pancreatic digestive neuroendocrine tumors well differentiated. Most of time they are developed from enterochromaffin cells of the digestive tract. Most of them are localized in ileum, rectum, stomach and appendix. Only bronchi are a frequent extra-digestive localization (20 to 25%). Most of these tumors are asymptomatic and discovered incidentally during a laparotomy or secondary to the exploration of a carcinoid syndrome. From a case report and a recent review of literature, diagnosis, histology and treatment of small bowel carcinoid tumors are summarized.

Elective laparoscopic colonic resection for diverticular disease: results of a multicenter study in 179 patients.

BACKGROUND: We undertook a retrospective multicenter study of elective laparoscopic sigmoidectomy for diverticulitis in order to assess the safety and the results of the procedure performed by a large number of surgeons. MATERIALS AND METHODS: Between January 1998 and April 1999, the French Society of Laparoscopic Surgery recruited retrospectively 179 patients from 10 surgical units, operated on for elective laparoscopic sigmoidectomy. There were 94 men and 85 women with a mean age of 58 years (range, 30-82). The indications for surgery were acute attacks in 123 cases, complicated diverticulitis in 47 cases, and miscellaneous in 9 cases. RESULTS: The performed procedure was a successful laparoscopic assisted sigmoidectomy in 154 cases (with totally intracorporeal anastomosis in 136 cases and hand-sewn anastomosis via small incision in 18 cases). The mean operation time was 223 min +/- 79 (range, 100-480). There was no mortality and 23 complications occurred in 23 patients (14.9%). Postoperative ileus lasted 2.5 +/- 0.9 days (range, 1-6), and oral intake started after 3.3 +/- 1.3 days (range, 1-12). The mean postoperative stay was 9.3 days (range, 4-50). Conversion to laparotomy was necessary in 25 cases (13.9%). The essential causes of conversion were obesity, severe adhesions, and colonic inflammation. The mean postoperative stay for the 25 converted patients was 13 +/- 8.5 days (range, 7-42). CONCLUSION: Elective laparoscopic sigmoidectomy for diverticulitis is feasible and is safe. The complication and mortality rates are similar to those observed after open procedures. For experienced surgical teams, laparoscopic colonic resection is a good approach for selected patients suffering from symptomatic diverticulitis.

[Micrometastases in colonic cancers: diagnostic methods and prognostic elements].

Micrometastasis are defined by the existence of cells or groups of cells in target organs. In the particular cas of colon cancers, although lymph node involvement is frequent, metastatic medullary involvement (while rarely at the origin of identified metastasis) can also be observed. Furthermore, micrometastatics cells can be identified in the circulating blood. This research relies on recent technics of immunocytochemistry with image analysis or molecular biology technics (generally PCR or RT-PCR). It is essential to have a specific reliable marker of metastatic cells. The prognostic value of identifying micrometastasis in organs also remains to be defined.

[Suspected acute appendicitis. Role of enhanced helical computed tomography. Prospective study of 100 patients].

AIM OF STUDY: To assess the diagnosis accuracy of helical computed tomography (CT) in patients with suspected appendicitis. PATIENTS AND METHODS: This prospective study included 100 consecutive patients hospitalized for suspected appendicitis. There were 57 men and 43 women with a median age of 30 years (range: 17-91). An enhanced helical CT was performed at admission, without digestive opacification. Four criteria were interpreted as positive signs for appendicitis: appendix enlarged > or = 7 mm, right lower quadrant inflammation, stercorolith, and peri-appendicular collection. The patient was managed by the surgeon without knowing the result of CT. The final diagnosis was made pathologically. RESULTS: Eighty-one patients were operated on laparoscopically for suspected appendicitis. Intraoperative diagnosis was corrected in three cases and 78 appendectomies were performed (73 histological appendicitis, six normal appendix). Final diagnosis was a medical disease in 19 patients. The findings of 67 CT were interpreted as positive (63 true positive and four false positive) and the findings of 33 CT were interpreted as negative (24 true negative, nine false negative). Sensitivity was 87%, specificity was 86%, positive predictive value was 94%, and negative predictive value was 73%. If the nine false negative cases with minimal lesions at pathological examination were considered as true negative, the rates would be 100%, 89%, 94%, 100%, respectively. CONCLUSION: Enhanced helical CT is a good imaging diagnostic tool for suspected appendicitis. It may reduce the number of patients admitted for observation and decrease the rate of negative appendectomy.

[Laparoscopic treatment of perforated duodenal ulcers. Results of a retrospective multicentric study. French Society of Laparoscopic Surgery].

STUDY AIM: The aim of this multicentric retrospective study was to report procedures, mortality and morbidity rate in a series of patients operated on for perforated duodenal ulcer with a laparoscopic approach. PATIENTS AND METHODS: Four-hundred and nineteen patients from 18 centers were included. The duration of the study was ten years (1990 to 1999). There were 299 men and 120 women aged from 19 to 98 years (mean: 48 years). The ASA scores were as follows: I (48.7%), II (31.3%), III (17.5%), IV (2.5%). The mean duration between the onset of perforation and the time of operation was 13.4 hours (range: 1-70). The surgical procedures were suture (76.7%), epiploplasty (9.9%), only irrigation of the abdominal cavity (2.7%). RESULTS: Conversion into laparotomy was performed in 10.6% of the patients. Mean operative time was 85 minutes. The morbidity and mortality rates were 13.4 and 1.4% respectively. Seventeen patients were reoperated because of fistula (n = 5), intra-abdominal abscess (n = 5), small bowel obstruction (n = 4), bleeding ulcer (n = 1), iatrogenic perforation of the gallbladder (n = 1) and small bowel (n = 1). Mean hospital stay was 8.5 days. All patients were discharged with a medical treatment of the peptic ulcer disease and in most of the cases, with antibiotics for Helicobacter pylori eradication. Six patients out of 96 with a medical history of chronic peptic ulcer underwent a vagotomy. CONCLUSION: Laparoscopic repair of perforated duodenal ulcer is a safe option providing low rates of morbidity, reoperation and mortality, and can be considered the treatment of choice.

[Laparoscopic treatment of perforated duodenal ulcer].

OBJECTIVE: The aim of this study was to determine if laparoscopic simple closure for perforated duodenal ulcer is possible, efficient and safe. METHODS: Thirty-five consecutive patients with perforated duodenal ulcer and peritonitis were treated by simple closure, peritoneal lavage and omentoplasty. This treatment was performed laparoscopically. RESULTS: Diagnosis was confirmed in all cases. Conversion to laparotomy was necessary in two patients due to a technical problem and poor tolerance to pneumoperitoneum, respectively. Mean operative time was 120 min. Morbidity and mortality rates were 2.8%. Mean hospital stay was 7.8 days. No recurrence was found after eradication of Helicobacter pylori with a long-term follow-up of 38 months. CONCLUSION: Laparoscopic suture of perforated duodenal ulcer is possible and safe. It can avoid laparotomy with septic complications in peritonitis. In emergency there is no place for radical treatment of ulcer disease because of efficiency of medical treatment.

[Non-secreting pheochromocytoma of the broad ligament revealed by appendicular peritonitis].

BACKGROUND: Non-secreting pheochromocytoma is an endocrine tumor located in the adrenal medulla in 85% of the cases. Extra-adrenal localizations account for the other 15%. A broad ligament localization related to an accessory adrenal gland is exceptional. CASE REPORT: A tumoral formation was observed during computed tomographic exploration of appendicular peritonitis in a 25-year-old patient. The tumor had developed from an ectopic adrenal gland included in the large ligament of the uterus. Pathology reported non-secreting pheochromocytoma confirmed by immunolabeling. DISCUSSION: The broad ligament localization is exceptional for pheochromocytomas and may mislead diagnosis. Resection is the only treatment. Recurrence and metastases have been reported to develop in some cases many years later, particularly after incomplete resection. Pathogenically, this tumor is remnant embryonic chromaffin tissue issuing from the parasympathetic nodes and developing in an ectopic adrenal gland.

Parietal mesh abscess as an original presentation of cancer of the caecum.

We report a case of cancer of the caecum in a 71-year-old male who presented with parietal mesh abscess. Two years before, he was treated for a right inguinal hernia by insertion of a Dacron mesh. CT scan then colonoscopy determined the existence of a voluminous caecal tumor perforated in the abdominal wall with an important abscess around the mesh. Right colectomy and parietal muscles excision were performed completed with postoperative radiochemotherapy. At 2 years, there is no evidence of recurrence. Atypical features with a hernia mesh repair associated with a sudden change in the patient's condition should alert the clinician to the possibility of a further subjacent pathological process.

Elective laparoscopic-assisted colectomy for diverticular disease. A prospective study in 50 patients.

BACKGROUND: Although several recent reports described the different methods utilized for laparoscopic colon resection, only a few of them questioned whether the procedure is appropriate for the surgical treatment of diverticular disease. To assess this question, we performed a retrospective study of 50 consecutive patients operated using laparoscopic assistance to remove the sigmoid colon for diverticular disease. METHOD: The surgical technique was a laparoscopically assisted procedure that included mobilization of the left colon and vascular ligation laparoscopically and then, via a small abdominal incision, division of the colon, removal of the specimen, and hand-sewn anastomosis. RESULTS: The surgical goal was achieved in 46 cases, with a conversion rate of 8%. The mean operative time was 195 min (range 150-280 min). There was no mortality, and the morbidity rate was 14%. There were no complications directly related to the laparoscopic technique. The mean return of regular bowel habits was 3.2 days, and the median postoperative stay was 10 days. CONCLUSIONS: These preliminary results suggest that laparoscopic-assisted sigmoidectomy can be used safely for the surgical treatment of diverticular disease.

[Laparoscopic appendectomy in the adult].

AIM OF THE STUDY: The benefits of laparoscopic appendectomy remain controversial. The aim of the study was to evaluate the advantages and disadvantages of this technique. MATERIAL AND METHODS: Four hundred and forty-eight patients operated on for suspected appendicitis during a 5-year period were analysed in a retrospective study. The preoperative diagnosis was corrected in 21.4% of the cases (8.1% for males and 28.7% for females) and the conversion rate was 9.7%. There were 17 patients with generalized peritonitis and 28 with localized peritonitis. During the past year, this surgical method was introduced in another hospital and a prospective study included 92 consecutive patients operated on for appendicitis. The operating time was 53 minutes and the conversion rate was 7.6%. There were five patients with generalized peritonitis and eight with localized peritonitis. RESULTS: There were no postoperative deaths. In the first period, the morbidity rate was 2.3% in the laparoscopic group without conversion. After pathological examination, there was a 14.2% rate of normal appendix. The mean hospital stay was 4.3 days. In the second period, there were only three minor complications and the mean hospital stay was 4.19 days. CONCLUSION: The choice of laparoscopic approach is associated with some advantages: corrections of the diagnosis (mainly in young women) and simplification of the postoperative course, provided that the surgeon has sufficient experience.

Factors influencing long-term survival in 100 cases of small intestine primary adenocarcinoma.

BACKGROUND: Factors influencing long-term survival in patients undergoing operation for adenocarcinoma of the small intestine are poorly recognized. METHODS: Retrospective study of 100 cases culled within a 10-year period by questionnaire, including 59 males and 41 females, median age 61 years (range 30 to 86). No patients were lost to follow-up (median 27 months). All patients underwent operation: curative in 65% and palliative in 35%. RESULTS: Overall actuarial 5-year survival was 38%, 0% after palliative treatment and 54% after curative resection. In patients undergoing curative resection, 5-year survival was 63% when the lymph nodes were not involved, and 52% when they were; 57% when the serosa was not involved, and 53% when it was; 56% when the tumor was well or moderately well differentiated and 40% when it was undifferentiated. Other factors influencing long-term survival were the emergency setting, the site, the multiplicity, and the size of tumor (none with statistically significant differences). Five and 10-year survival was 78% and 69%, respectively, when the patient was anemic compared with 35% and 17%, respectively when the patient was not (P <0.01). There were 14 patients with previous carcinoma, 2 with Crohn's disease, and 1 each with celiac disease and ileal tuberculosis. There were also 8 patients with associated duodenal and proximal jejunal polyps. Thirteen patients sustained a total of 14 further cancers. CONCLUSIONS: Patients should be followed up closely because the possibility of sustaining another abdominal carcinoma is high (16%). As associated polyps are nearly always duodenal or jejunal, preoperative or intraoperative endoscopy of the upper gastrointestinal tract including the initial portion of the jejunum should be able to detect their presence and reduce the risk of early recurrence.
