Laparoscopic liver resection.
BACKGROUND: This paper describes a 10-year experience of laparoscopic liver surgery, including several major hepatectomies for malignant tumours. METHODS: Of 243 hepatectomies carried out between January 1995 and December 2004, 113 (46.5 per cent) were performed by laparoscopy and 89 were included in this retrospective study. RESULTS: Twenty-four laparoscopic hepatectomies (27 per cent) were for benign disease and 65 (73 per cent) for malignant tumours, including hepatocellular carcinoma (HCC) in 16 patients and colorectal metastasis (CRM) in 41. Minor hepatectomy was performed in 51 patients and major hepatectomy (three or more Couinaud segments) in 38. Conversion to laparotomy was necessary in 12 patients and perioperative blood transfusion in eight. One patient with cirrhosis who underwent right hepatectomy for HCC with conversion to open surgery died 8 days after surgery. Major morbidity occurred in eight patients (16 per cent) having minor hepatectomy and in 11 (29 per cent) of those having a major resection. The 3-year overall and disease-free survival rates for patients with CRM (mean follow-up 30 months) were 87 (11 patients at risk) and 51 (6 patients at risk) per cent respectively. Corresponding values for patients with HCC (mean follow-up 40 months) were 85 (10 patients at risk) and 68 (5 patients at risk) per cent. CONCLUSION: In experienced hands, the results of laparoscopic liver surgery are similar to those for laparotomy.

[Laparoscopic incisional hernia repair: prospective non randomized trial in 51 cases].
AIM OF THE STUDY: Insertion of a mesh in treatment of incisional hernias reduces the risk of recurrence. A single prospective randomized trial have compared laparoscopic and open approach: there were less postoperative complications and fewer recurrences in the laparoscopic group. Aim of this prospective trial was to control these results. PATIENTS AND METHODS: From January 2000 to May 2005, 51 consecutive incisional hernias were operated on by a laparoscopic approach. Incisional hernia was single in 41 and double in 5. It was median in 41 and lateral in 10. Previous hernia repair was noticed in 33.3%. Main criteria was recurrence. We have considered whether one of the following criteria was associated with the risk of recurrence: sex, obesity, previous repair, pre and preoperative sizes of the hernia, uni or multi orificial aspect of the hernia, median or lateral location, mesh size, ratio mesh surface/hernia surface. Others were postoperative mortality and morbidity, duration of hospitalisation and occurrence of late events. RESULTS: At 2 years all patients were followed. Follow up achieved 3 years in 23 cases and 4 years in 9. Recurrence was observed in 7 (13.7%). None predictive factor was disclosed. No death occurred. Median postoperative pain score at D1, D2 and D3 was respectively 3.1+/-1.9, 2.9+/-2.3 and 2.3+/-2.1. Mean postoperative stay was 4.1+/-1.9 days. Seven postoperative complications occurred, al benign. During follow-up 18 events were noticed and of these 8 were chronic abdominal pain. CONCLUSION: This technique could be employed for every type of incisional hernia but peristomial hernias (not assessed in this study) and every patient. Technical improvements ought to be find to reduce recurrence rate.

Gemcitabine combined with oxaliplatin (GEMOX) in advanced biliary tract adenocarcinoma: a GERCOR study.
BACKGROUND: Since gemcitabine-oxaliplatin (GEMOX) has been used in pancreatic adenocarcinoma, we studied its activity and tolerability in advanced biliary tract adenocarcinoma (ABTA). PATIENTS AND METHODS: Consecutive adult patients with confirmed ABTA were recruited from four centers. Those in group A had performance status (PS) 0-2, bilirubin <2.5x normal and received GEMOX as first-line chemotherapy. Those in group B had PS >2 and/or bilirubin >2.5x normal and/or prior chemotherapy. All received gemcitabine 1000 mg/m2 as a 10 mg/m2/min infusion on day 1, followed by oxaliplatin 100 mg/m2 as a 2-h infusion on day 2, every 2 weeks. RESULTS: Tumor sites were gallbladder (19), extrahepatic bile ducts (5), ampulla of vater (3) and intrahepatic bile ducts (29). Results for group A (n = 3) were: objective response 36% [95% confidence interval (CI) 18.7% to 52.3%], stable disease 26%, progressive disease 39%, median progression-free survival (PFS) 5.7 months and overall survival (OS) 15.4 months. Results for group B (n = 23) were: objective response 22% (95% CI 6.5% to 37.4%), stable disease 30%, progressive disease 48%, PFS 3.9 months and OS 7.6 months. National Cancer Institute Common Toxicity Criteria grade 3-4 toxicities were neutropenia 14% of patients, thrombocytopenia 9%, nausea/vomiting 5% and peripheral neuropathy 7%. CONCLUSION: The GEMOX combination is active and well tolerated in ABTA.

Laparoscopy in the last decade of the millennium: have we really improved?
BACKGROUND: The aims of the study were to evaluate the evolution of laparoscopic surgery during the past decade in terms of variations in the quality (complexity) of the procedures performed and of modifications in patient outcome. METHODS: A retrospective analysis was performed of 3022 consecutive patients undergoing 99 different laparoscopic procedures at a center specialized in laparoscopic abdominal surgery. All the procedures were classified according to three classes of complexity. Results relating to the first 1511 patients were compared to those of the last 1511 patients. RESULTS: In the second group, medium- to high-class complexity procedures significantly increased, conversion rate was higher only for straightforward procedures, duration of low- to medium-class complexity procedures decreased, only the rate of slight complications increased, and mean postoperative hospital stay was longer. Frequency of conversion in medium- to high-class complexity procedures and severe complications was not different in the two periods. CONCLUSIONS: The quality of laparoscopic surgery has improved during the past decade, with no increase in the frequency of conversion or of major complications.

[Natural history of the pancreatic stump after duodenopancreatectomy of the pancreatic head].
UNLABELLED: Major complications following pancreaticoduodenectomy are thought to be chiefly associated with exocrine secretion of the pancreatic remnant which is not well known. This work aims to assess the exocrine secretion of the pancreatic remnant within the early post-operative period. PATIENTS AND METHODS: Seventy-five patients undergoing pancreaticoduodenectomy for presumed tumour were included in a prospective multicentre study. A tube was inserted in the pancreatic duct at the time of construction of the pancreatic anastomosis. Peripancreatic drainage was routinely used. Pancreatic juice and peripancreatic drainage fluid were collected and measured and pancreatic enzyme monitored. For 7 days patients received total parenteral nutrition and continuous infusion of randomly Somatostatin 14 (S-14) at a dose of 6 mg/24 h (days 1-6) and 3 mg/24 h (day 7) or matching placebo. Pancreatic fistula was defined as a daily drainage of more than 100 cc of amylase-rich fluid after day 3, persisting after day 12 or associated with symptoms or needing specific treatment. RESULTS: Daily output of pancreatic juice was low during the first postoperative day and then increased gradually until day 5. A high enzyme concentration was observed in pancreatic juice on the first post-operative day. S-14 infusion resulted in a significant decrease of both pancreatic fistula rate and enzyme concentration in peripancreatic fluid. CONCLUSIONS: During the first postoperative days, the outflow of the exocrine secretion of the pancreatic remnant is low but contains a high enzyme concentration with significant leaks within the peripancreatic area. S-14 infusion results in a decrease of pancreatic juice leaks from the pancreatic remnant.

Impact on survival of surgery after concomitant chemoradiotherapy for locally advanced cancers of the esophagus.
BACKGROUND: To evaluate the results of chemoradiotherapy with or without surgery in locally-advanced esophageal carcinomas (T3 and/or nodal involvement). METHODS: One hundred twelve patients with locally-advanced carcinoma of the esophagus without histologically proven invasion of the tracheobronchial tree or distant visceral metastases were treated with concomitant chemoradiotherapy followed by re-evaluation; surgery was performed or chemoradiotherapy continued, based on tumor regression and the patient's general status. Chemoradiotherapy consisted of concomitant 5-fluorouracil (5FU)(1 g/m(2) day 1-3), cisplatinum (50 mg/m(2) day 1 and 2), and external beam irradiation up to a dose of 40 or 43.2 Gy. After a 4-week rest period, radical esophagectomy or a new cycle of chemoradiotherapy (up to a total dose of 65 Gy) was performed. RESULTS: A complete clinical response was obtained in 25.7% of the patients and a partial response in 45.9%. Fifty patients underwent surgery, but only 38 patients had an esophagectomy. Post-esophagectomy mortality was 5.3%. A complete histologic response rate of 23.7% was obtained. Two- and 5-year survival rates were, respectively, 41.5% and 28.6% for the whole population. According to multivariate analysis, prognostic factors for survival were Karnofsky index, esophagectomy, and response to chemoradiotherapy. Five-year survival for patients who experienced a partial response to radiation and chemotherapy was 49.1% for those who had surgery and 23.5% for those treated without surgery (p = 0.003). There was no obvious benefit for the small number of patients treated surgically after complete response to radiation and chemotherapy. Toxicity, essentially hematologic, was moderate. CONCLUSION: For locally-advanced esophageal carcinomas, esophagectomy, after concomitant chemoradiotherapy, could improve the survival rate, especially for patients who responded partially to the latter.

Randomized controlled multicentre trial of somatostatin infusion after pancreaticoduodenectomy.
BACKGROUND: It remains debatable whether somatostatin can prevent pancreatic fistula and other pancreatic stump-related complications following pancreaticoduodenectomy. This study assessed the effects of somatostatin-14 (S-14) on pancreatic remnant exocrine secretion. METHODS: This was a double-blind, randomized, placebo-controlled trial in patients undergoing pancreaticoduodenectomy for malignancy. Patients received a continuous infusion of S-14 (n = 38) or placebo (n = 37) for 7 days. Pancreatic juice and peripancreatic drainage fluid was collected and measured, and pancreatic enzymes were monitored daily. Postoperative complications were recorded. RESULTS: S-14 infusion was associated with a decrease in median daily pancreatic juice and pancreatic amylase output. Amylase concentration and output in the peripancreatic drain fluid were significantly lower after S-14 infusion than in the control group (both P < 0.05). The incidence of clinical pancreatic fistula (two of 38 versus eight of 37; P < 0.05) and total pancreatic stump-related complications (five of 38 versus 12 of 37; P < 0.05) was lower in patients treated with S-14. Duration of hospital stay was shorter after S-14 (18 versus 26 days; P = 0.01). CONCLUSION: Although the effect of S-14 on exocrine secretion remains difficult to demonstrate, it did reduce pancreatic juice leakage from the pancreatic remnant.

[Chemotherapy with cisplatinum, carboplatin and 5FU-folinic acid, followed by concomitant chemo-radiotherapy in unresectable esophageal carcinomas].
UNLABELLED: The best chemotherapeutic regimen for advanced carcinoma of the esophagus remains to be determined. We have evaluated a combination of carboplatin, cisplatin and 5FU modulated by folinic acid. Patients. Twenty-seven patients (median age 57 yrs) with an unresectable carcinoma of the esophagus were included in this trial: 9 patients with a local relapse after surgery, 6 patients with a locally advanced (T4) tumor, and 12 patients with metastasis. Treatment schedule. Initial chemotherapy : carboplatine IV d1, AUC4; 5FU: bolus injection of 400 mg/m2 d1, followed by a continuous infusion of 600 mg/m2/24 h, d1 and d2; folinic acid (200 mg/m2) IV, before the 5FU bolus, d1 and d2; cisplatine 80 mg/m2, d3; on d15 and d16, 5FU and folinic acid were repeated with the same schedule. The second cycle began on d28. Concomitant chemo-radiotherapy with 5FU (1,000 mg/m2 d1 to d3), cisplatine (50 mg/m2 d1 and d2) and external irradiation (20 Gy in 10 fractions from d1 to d12) was then performed, for three cycles (until a total dose of 60 Gy). Results. TOXICITY: neutropenia grade 3-4 (32%), thrombopenia grade 3-4 (18%). More important, a lymphopenia (< 500/mm3) was noted in 12 patients (43%). Accordingly, 4 serious infectious complications were observed, with three toxic deaths. Objective response rate: 44% after initial chemotherapy; 75% after chemoradiotherapy, with 8 complete responses (38%). Median survival was 7.4 months, with a one- and two-year survival of 33% and 17,8%, respectively. Conclusion. This association of cisplatin, carboplatin, and 5FU did not offer a better response rate than the classical 5FU-cisplatinum association. But serious infectious complications occurred during the trial. We do not recommended further evaluation of this biplatinum therapy with 5FU in advanced esophageal carcinomas.

[Can common bile duct lithiasis be removed laparoscopically without external biliary drainage?].
AIM OF THE STUDY: To evaluate the indications, feasibility and results of laparoscopic treatment of common bile duct stones without biliary drainage. PATIENTS AND METHODS: Between 1992 and 1999, laparoscopic procedures were performed in 70 consecutive patients, mean age 60 +/- 15 years (range: 18-82). Stone removal was attempted via the cystic duct (n=25) or choledocotomy (n=45). The emptiness of the common bile duct was checked by intraoperative cholangiography or endoscopy. After choledocotomy, closure was performed by interrupted or non-interrupted suture with slowly resorbable thread. Transcystic drainage was used whenever necessary. RESULTS: Nine conversions to laparotomy were necessary (12.8%). Among the 61 patients who had an exclusively laparoscopic procedure, 21 were treated via the transcystic route and 40 through choledocotomy. Biliary endoscopy was possible in only 10 of the 21 patients (47.6%) treated via the transcystic route and in all with choledocotomy. No biliary drainage was used in 16 of the 21 patients treated via the transcystic route and in 39 of the 40 treated through choledocotomy. The 30-day mortality was 1/61 (1.6%). Morbidity was 9.8% and 2 patients underwent a second laparoscopic procedure (one fistula on a choledocotomy suture, one hemoperitoneum of unknown origin). An endoscopic sphincterotomy for residual stone was necessary in 4 patients (4/61, 6.5%), 2 after choledocotomy for an unrecognized stone without biliary drainage. CONCLUSIONS: These results confirm the feasibility of laparoscopic treatment of common bile duct stones and suggest it can be performed without biliary drainage in most cases.

[Achalasia mimicking psychiatric eating disorders].
Anorexia nervosa and psychogen vomiting are psychiatric eating disorders characterized by unexplained weight loss and induced vomiting. These diagnoses require absence of somatic disease. Achalasia is a primary disorder of the esophagus that can be responsible for the same symptoms. This may occult the real diagnosis, especially as dysphagia is not constant and variable in time. We report four cases of achalasia mistakenly diagnosed and treated as anorexia nervosa or psychogen vomiting. Achalasia was unrecognized because specific symptoms, such as dysphagia, were overlooked or misinterpreted by the patients' physicians and psychiatrists, or by the patients themselves. In patients with such eating disorders considered to be psychiatric, physicians should inquire about signs suggestive of achalasia. The diagnosis of achalasia is suspected by imaging and endoscopy, and confirmed or ruled out by manometry.

[Minimally invasive surgery for diverticula of the thoracic esophagus. Results in 11 patients].
OBJECTIVES: Surgical treatment of diverticula of the esophagus is associated with substantial mortality and morbidity. Few data have been published concerning results of minimally invasive surgery. The aim of the study was to retrospectively assess the results of minimally invasive surgery (either thoracoscopy or laparoscopy) in a first series of patients with diverticula of the thoracic esophagus. METHODS: Eleven consecutive patients with symptomatic thoracic diverticula of the esophagus were operated on between December 1992 and March 1999. Five were operated on by right thoracoscopy, 4 by laparoscopy and 2 by thoracoscopy and laparoscopy. The procedure performed varied according to the location and the macroscopic aspect of the diverticulum, as well as of the associated disorders (gastroesophageal reflux, hiatal hernia and/or motor disorders). RESULTS: Postoperative mortality was nil. Three patients developed an esophageal fistula; one with an esophago-bronchial fistula required another operation. Postoperative pain was treated with morphine (median duration 4 days) or IV paracetamol (5 days). Long term results were excellent in 1 patient, good in 6, fair in 2 and poor in 2. These 2 latter patients were operated on another time. One of them was operated on 3 years later for aperistalsis of the esophagus and the other one was operated 4.5 years later for paraesophageal hernia; late results of these operations were fair. CONCLUSION: These results suggest that minimally invasive surgery does not confer significant benefit compared with open surgery in the treatment of diverticula thoracic esophagus.

Management and long-term results of surgery for localized gastric lymphomas.
BACKGROUND: High- and low-grade gastric lymphomas (GL) differ in their behavior and chemosensitivity. Surgery has to be reevaluated according to the histologic grade of malignancy. We aimed to assess the place of surgery in the management of GL and its results after long-term follow-up. METHODS: Among 54 patients with primary GL prospectively enrolled from 1984 to 1990, 45 with localized disease were studied. Primary resection was done whenever safe. All patients received chemotherapy adapted to the grade of malignancy and/or to the completeness of the resection. RESULTS: Among 18 low- and 27 high-grade GL, 35 patients had primary resections; of those, 23 were complete. The complete response rate for all patients with low- and high-grade GL was 67% and 89%, respectively. After a median follow-up of 8 years, the disease-free survival rates for low-grade GL and high-grade GL were 94% and 89%, respectively. It was better after complete resection. CONCLUSION: Complete resection is a major determinant of prolonged complete remission.

[Immediate postoperative complications after a laparoscopic partial posterior fundoplication. Early laparoscopic reoperation].
AIM OF THE STUDY: The immediate postoperative course of laparoscopic partial posterior fundoplication can be complicated by severe dysphagia or paraesophageal hernia. The aim of this study was to describe the technical causes of these complications. PATIENTS AND METHOD: Four patients, operated for gastroesophageal reflux disease by laparoscopic partial posterior fundoplication, developed severe dysphagia (n = 2) or paraesophageal hernia (n = 2) during the immediate postoperative period. A barium swallow examination visualized the complication in both cases of dysphagia and in 1 case of paraesophageal hernia. The correct diagnosis was established by CT scan in the other case of paraesophageal hernia. Reoperations were performed by laparoscopy, 3 days (n = 2) or 6 days (n = 2) postoperatively. RESULTS: Dysphagia was due to compression of the esophagus against the hiatus by the fundoplication. A new and looser fundoplication was easily performed. Dysphagia was no longer present postoperatively. The two patients were symptom-free after 6 and 12 months of follow-up, respectively. In the cases of paraesophageal hernia, the bottoms of the crura were torn. In the patient reoperated 3 days postoperatively, the procedure was easily performed, the postoperative course was uneventful and the patient was symptom-free after a follow-up of 20 months. In the patient reoperated 6 days postoperatively, the upper part of the stomach had moved into the left pleural cavity, the procedure was difficult due to inflammation and thickening of the gastric wall, and the postoperative course was uneventful, but reflux recurred 18 months later. CONCLUSION: When severe dysphagia or paraesophageal hernia occurs during the immediate postoperative course of laparoscopic partial posterior fundoplication, reoperation, possibly by laparoscopy, identifies and cures the technical defects. Based on our experience, we suggest that surgical cure of paraesophageal hernia is easier when performed during the immediate postoperative period.

Preoperative nonresectability criteria used for pancreatic head adenocarcinoma: a practical survey among gastroenterologists and surgeons. Société Française de Chirurgie Digestive.
Preoperative nonresectability criteria for carcinoma of the pancreatic head remain controversial. We sought to assess prospectively the preoperative criteria used currently in clinical practice and to determine the different therapeutic strategies used between gastroenterologists (GEs) and digestive surgeons (Ss). The evaluation comprised all of the registered GEs (n = 3,466) and Ss (n = 687) who were sent a questionnaire surveying nonresectability criteria. The hypothesis in question concerned adenocarcinoma of the pancreatic head in a patient in the absence of general operative contraindication. Six hundred fifteen complete responses to the questionnaire were received (GEs, 426; Ss, 189). The mean estimated percentage of resected tumor was 22% (GEs, 19%; Ss, 31%; p < 0.0001). Preoperative nonresectability criteria differed between the two groups and included weight loss >25% (percentage of GEs using this criterion, 57%; Ss, 48%; p < 0.04), duodenal wall invasion (GEs, 30%; Ss, 4%; p < 0.001), gastric extension (GEs, 55%; Ss, 23%; p < 0.001), invasion of gastroduodenal artery (GEs, 58%; Ss, 19%; p < 0.001), invasion of superior mesenteric artery (GEs, 85%; Ss, 92%; p < 0.02), invasion of portal vein (GEs, 78%; Ss, 52%; p < 0.001), tumor diameter >6 cm (GEs, 52%; Ss, 38%; p < 0.001), peripancreatic lymph nodes (GEs, 33-69% depending on the node area; Ss, 5-52%; p < 0.02-0.001). Consensual criterion used by >85% of GEs and Ss was celiac trunk invasion. Criteria rejected by >85% both of GEs and Ss were back pain, weight loss <25%, and tumor diameter < or = 5 cm. Criteria without consensus (used or rejected by <85% of GEs and Ss) were superior mesenteric vein and hepatic artery invasion. The preoperative nonresectability criteria used in determining operative resectability differs significantly between medical and surgical gastroenterologists. This study is the first to quantify this difference. These results underline the need for consensus agreement in the criteria of resectability.

[Enucleation of intraductal papillary-mucinous tumor of the head of the pancreas. Report of 2 cases].
Intraductal papillary-mucinous tumors of the pancreas are characterized by malignant transformation of unpredictable occurrence because of their unknown natural history. Surgical treatment is duodenopancreatectomy or left pancreatectomy even for benign tumors. We report 2 cases of benign intraductal papillary-mucinous tumor confined to the head of the pancreas and treated by enucleation.
