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.

Laparoscopic treatment of acute small bowel obstruction: a multicentre retrospective study.

BACKGROUND: Laparoscopic surgery is thought to promote early recovery and quicker return to bowel function. The objective was to evaluate the rate and predictive factors of success, the causes of failure, the morbidity, and mortality during and after hospitalization, as well as to determine whether laparoscopic treatment of acute small bowel obstruction offers the same benefits as for other laparoscopic procedures. METHODS: The records of 308 patients with acute small bowel obstruction treated laparoscopically in 35 centres between 1 October 1988 and 30 September 1996 were retrospectively reviewed. RESULTS: Treatment was implemented completely by laparoscopy ('success' group) in 168 patients (54.6%). Conversion to laparotomy ('failure' group) was required in 140 patients (45.4%; during the same operation in 126 patients and after a median delay of 4 days (range: 1-12 days) in 14 patients). There were significantly more successes in patients with a history of one or two surgical interventions than in those with more than two (56% vs 37%; P < 0.05). There were significantly more successes in patients who had undergone appendectomy only (67/94; 71%) than in patients who (i) had no antecedent surgery (52%; P < 0.05), or (ii) underwent other surgery (33%; P < 0.001). The rate of success was significantly higher (P < 0.001) in patients operated on early (< 24 h) and in patients with bands (54%), than in those with adhesions (31%) or with other causes of obstruction (15%). The median duration of postoperative ileus was significantly shorter in the 'success' group than in the 'failure' group (2 days vs 4 days; P < 0.001). The median duration of postoperative hospital stay was shorter in the 'success' group than in the 'failure' group (4 days vs 10 days; P < 0.001). Fewer immediate wound complications were sustained in the 'success' group than in the 'failure' group (1.2% vs 10.7%; P < 0.001). The total number of immediate or delayed complications and particularly the number of recurrent obstructions after hospitalization as well as the number of deaths did not differ significantly between the two groups. CONCLUSIONS: Successful laparoscopic treatment of small bowel obstruction can be expected in patients who are seen early, and who have had one or two previous interventions (particularly appendectomy, especially if bands are found).

[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.

[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.

[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.

[Results of elective segmental colectomy done with laparoscopy for complicated diverticulosis].

OBJECTIVES: To analyze a unicentric series of 100 consecutive elective laparoscopic colon resections for diverticular disease and to evaluate in intention to treat the early- and middle-term postoperative results. METHODS: From February 1993 to March 1998, 100 colon resections for complicated diverticular disease were performed through laparoscopy with systematic mobilization of the splenic flexure and resection of the rectosigmoid junction. The colorectal anastomosis was stapled or manual without proximal stoma. In 53 females and 47 males (mean age 60.4 years), indications for surgery were: one or more attacks of acute diverticulitis (n = 70), abscess (n = 17), symptomatic stenosis (n = 8), colovesical fistula (n = 4) and diverticular bleeding (n = 1). RESULTS: Mortality was nil. The conversion rate was 9%, never for anesthetic reasons. The mean operating time was 226 +/- 68 min. There was no splenic or ureteral injury. The morbidity at 30 days was 19% with fistulae rate accounting for 2%, 2 patients were reoperated on. The median time for passage of flatus was 3 days and median length of hospital stay was 7 days. Late morbidity was 10%, one patient complained of retrograde ejaculation. CONCLUSION: This study demonstrates that laparoscopy is a safe alternative to laparotomy for elective one-stage colectomy for complicated diverticular disease.

[Gastric stromal tumors. Results of a multicenter study. French Associations of Surgery Research].

AIM OF THE STUDY: Gastric stromal tumours are not perfectly known. The aim of this retrospective multicenter study (29 centers) was to improve knowledge of these tumours. PATIENTS AND METHODS: From 1986 to 1994, 159 patients were operated on for leiomyomas (50), leiomyosarcomas (24), malignant/benign schwann cell tumours (10/29), automatic nerve tumours (4), leiomyoblastomas (28), spindle cell tumours (14). The mean duration of follow-up was 5 years. Presenting symptoms, diagnostic procedures, operative and pathological findings, evolution (recurrence, death) were recorded for each patient. RESULTS: Gastrointestinal bleeding and epigastric pain were the most common presenting symptoms (54% and 50% of patients, respectively). Endosonography was the most sensitive examination (97%). Malignant tumours size was greater than benign tumours size (12.6 cm versus 5.2 cm). Extension to contiguous organs or metastases were frequent (33% and 26% of patients, respectively). In 16 patients, pathological examination could not differentiate between malignant and benign tumour. Seven patients who had been operated on for a benign tumour (6%) developed a local (n = 4) or a metastatic (n = 3) recurrence. The 5-year survival rate was 40% for leiomyosarcomas, 28% for schwannosarcomas and 90% for malignant leiomyoblastomas. CONCLUSION: The main feature of stromal gastric tumours is the frequent difficulty to differentiate between malignant and benign tumours. The prognosis of malignant tumours depends on pathological types. The prognosis of benign tumours is uncertain since recurrences may develop.

5-Fluorouracil and cisplatin as palliative treatment of advanced oesophageal squamous cell carcinoma. A multicentre randomised controlled trial. The French Associations for Surgical Research.

OBJECTIVE: To compare chemotherapy with no chemotherapy as palliative treatment for oesophageal squamous cell carcinoma. DESIGN: Randomised study. SETTING: Multicentre trial in France. SUBJECTS: Of 161 patients with histologically confirmed oesophageal squamous cell carcinoma located more than 5 cm from the mouth of the oesophagus, five were withdrawn because of protocol violation. The remaining 156 patients, 149 men and 7 women, mean (SD) age 58 (9) years range 36 to 77, were randomly allocated to either a control group without chemotherapy (n = 84) or a group treated by chemotherapy (n = 72). Patients were divided into four strata: I = complete resection of the tumour but with lymph node involvement (n = 62); II = incomplete resection of tumour leaving gross tumour behind (n = 58); III = no resection because of local or regional invasion (n = 22) ; and IV = no resection because of distant metastasis (n = 14). Exclusion criteria were histologically confirmed tracheobronchial involvement, oesophagotracheal fistula, Karnosky score < 50, cerebral metastases, or hepatic metastases occupying more than 30% of the liver, peritoneal carcinomatosis, associated or previously treated ear-nose-throat carcinoma, or complete resection of tumour without lymph node involvement. INTERVENTIONS: 5 fluorouracil (5FU) and cisplatin (CDDP) were given in 5-day courses, once every 28 days, for a maximum of eight cycles. 5 FU, 1 g/m2, was infused for 24 hours after a water overload, during five days. Cisplatin was given either in one dose of 100 mg/m2 at the beginning of the cycle or 20 mg/m2/day over three hours for five days. Duration of treatment ranged from 6-8 months. OUTCOME MEASURES: Median and actuarial survival. The subsidiary endpoint was quality of survival judged by complications of treatment, swallowing disorders, and the duration of ability to feed normally. RESULTS: There was no difference in survival, either overall (median = 12 months) or in any of the strata. There were however significantly more patients with neurological (p < 0.003), haematological (p < 0.0001), and renal (p < 0.0002) complications in the treated group compared with the control group. Four patients (6%) died of complications of chemotherapy. The course of swallowing disorders did not differ between the two groups. The duration of autonomous oral feeding was exactly the same in both groups (median = 10.5 months). CONCLUSION: The results suggest that 5FU and CDDP do not help in patients with squamous cell carcinoma of the oesophagus whether or not the tumour has been resected.

Sclerosing encapsulating peritonitis: early and late results of surgical management in 32 cases. French Associations for Surgical Research.

OBJECTIVE: To propose guidelines for treatment based on the study of early and late outcome after various surgical procedures for sclerosing encapsulating peritonitis (SEP). PRIMARY BACKGROUND DATA: SEP is rare. The main complication is intestinal obstruction. Ideal treatment is resection of the membrane, whenever possible. Mortality and morbidity, however, have not been well analyzed. METHODS: The case records and histopathological reports of 32 operated cases of SEP (18 centers during 16 years) were retrospectively studied. Patients underwent four types of procedures: group 1 (n = 5), membrane resection; group 2 (n = 12), enterolysis with partial excision of the membrane; group 3 (n = 7), intestinal resection, and group 4 (n = 8), exploratory laparotomy only. Five cases were considered as idiopathic. Medical and surgical antecedent history for the 27 other cases (6 patients had associations) included laparotomy for carcinoma (n = 14) or benign disorders (n = 5), beta-blocker treatment (n = 4), cirrhotic ascites (n = 4), generalized peritonitis (n = 3) and continuous ambulatory peritoneal dialysis (n = 3). Indications for operation included subacute (n = 22) or acute intestinal obstruction (n = 6), abdominal mass (n = 8), other clinical presentations (n = 4) and asymptomatic SEP discovered during surgery for portacaval shunt (n = 1). Seven patients had two associated clinical presentations. All cirrhotic patients with ascites and the asymptomatic patient were in group 4. None of the imaging techniques (plain radiograms, barium follow-through, sonograms and CT scans) were formally contributive to the preoperative diagnosis of SEP. RESULTS: In group 1, both complicated patients, one with an inadvertent intraoperative intestinal wound, the other with a postoperative intestinal leak, healed uneventfully. In group 2, 4 inadvertent intraoperative intestinal wounds led to 4 postoperative leaks with 3 consequent deaths. One further patient died of persistent intestinal obstruction. In group 3, 1 inadvertent intestinal intraoperative wound healed uneventfully and 2 deaths, one due to persistent intestinal obstruction associated with anastomotic leakage and the other due to ventricular fibrillation, were noted. In group 4, there were no intraoperative wounds, no postoperative morbidity or deaths. The median follow-up was 49.5 months (range 4-142 months). Seven patients (1 or 2 in each group) experienced transient episodes of subacute intestinal obstruction between 1 month and 6 years after discharge, none of which required a repeat operation. Eight patients (in all groups) died of their initial cancer between 4 and 75 months after discharge. CONCLUSIONS: Our results suggest that: (1) resection of the membrane should be attempted when feasible; (2) in case of inadvertent intestinal wound(s), the most proximal one should be brought out as a stoma, and partial resections should not be anastomosed primarily, but (3) no surgical treatment is required in ascites, asymptomatic SEP or subacute intestinal obstruction.

[Laparoscopy versus the Shouldice intervention in the treatment of unilateral inguinal hernia: can the operative surcosts be minimized?].

AIMS: Laparoscopy is more expensive than Shouldice procedure for inguinal hernia repair. The aims of this study were to evaluate the overcost, to look for its causes and to propose a strategy of cost reduction. METHODS: One hundred and sixty three unilateral inguinal hernia repairs were performed from January 1995 to June 1996 in our institution, functioning under financial rule of total endowment. Forty five of the 163 procedures were laparoscopic procedures. The mean operative cost of each procedure was calculated from physician, personnel and equipment costs (amortization, consumable products and maintenance). RESULTS: The mean costs were 2,210 FF and 6,779 FF for Shouldice and laparoscopic procedures, respectively. This overcost of 4,569 FF was reduced to 893 FF by increasing surgeon's experience, which shortened operative duration and ward cost, and by the use of a non specific mesh fastened in place with threads. The mean operative cost of laparoscopy was then 3,103 FF. CONCLUSION: A change in surgical practice allows a reduction in the operative overcost of laparoscopic unilateral inguinal hernia repair by 80.4%.

[Colonic polyps considered unresectable by endoscopy. Removal by combinations of laparoscopy and endoscopy in 65 patients].

OBJECTIVE: To determine to what extent segmental colectomy could be avoided in patients with polyps though to be endoscopically unresectable by using combination laparoscopy and endoscopy. METHODS: Sixty-five patients referred for colonic polyps though to be unresectably by conventional endoscopy were studied. After analysis of the endoscopic findings, endoscopy was performed in a medicosurgical unit when possible, otherwise a surgical procedure was performed consisting of laparoscopy followed by colonoscopy. Therapeutic strategy depended on laparoscopic and endoscopic findings. RESULTS: Segmental colectomy was avoided in 44 patients (67.7%). Among them, 20 were treated by simple endoscopic polyp removal, 12 by laparoscopy-assisted colonoscopic polypectomy, 9 by laparoscopic wedge colonic resection and 3 by colotomy after colonic exteriorization and polyp resection. Laparoscopic or laparoscopy-assisted segmental colectomy was performed in 16. Segmental colectomy by laparotomy was necessary in 5. No complication occurred. CONCLUSION: Segmental colectomy for unresectable colonic polyps could be avoided in more than half of the patients using laparoscopy and colonoscopy combinations.

5-Fluorouracil and cisplatin therapy after palliative surgical resection of squamous cell carcinoma of the esophagus. A multicenter randomized trial. French Associations for Surgical Research.

BACKGROUND: The curative rate of surgical resection of squamous cell carcinoma of the esophagus is low. Reports on the efficacy of preoperative and postoperative chemotherapy are conflicting or have included limited disease or radical surgery alone. OBJECTIVE: The authors' objective was to study the results of chemotherapy on the duration and quality of survival in patients who have undergone palliative surgical resection for esophageal squamous cell carcinoma. PATIENTS AND METHODS: Of 124 patients with histologically proven esophageal squamous cell carcinoma situated more than 5 cm from the upper end of the esophagus, 4 patients were withdrawn for failure to comply with the protocol. The remaining 120 patients, 116 males and 4 females (mean age, 57 +/- 9 years), were randomly assigned to either a control group who were to receive no chemotherapy (68 patients) or to a group who were to be treated with chemotherapy (52 patients). Patients were subdivided into two strata as follows: (1) stratum I, complete resection of the tumor with lymph node involvement (62 patients) and (2) stratum ii, incomplete resection leaving macroscopic tumor tissue in situ or with metastases. Noninclusion criteria were histologically proven tracheobronchial involvement, esotracheal fistula, major alteration of general health status (Karnofsky score <50), cerebral or extensive (>30% of parenchyma) hepatic metastasis, peritoneal carcinomatosis, associated or previously treated upper airway cancer, or, conversely, complete resection of tumor without lymph node involvement. Chemotherapy was given in 5-day courses, every 28 days, with a maximum of 8 courses. Cisplatin was administered either as a single dose of 100 mg/m2 at the beginning of the course or as 20 mg/m2/day for 5 days given over 3 hours. 5- Fluorouracil (5-FU) (100 mg/m2/day) was infused over 24 hours for 5 days. The duration of treatment ranged from 6 to 8 months. The main aim was to establish median survival and actuarial survival curves. The subsidiary aim was to evaluate quality of survival as judged by complications due to treatment and the duration of autonomous oral feeding, that is, without palliative endoscopic treatment. No difference in survival was noted between the two groups, overall (median, 14 months), or between the strata. Conversely, significantly more patients in the treated group had hematologic, neurologic, and renal complications compared with the control group. Four patients died of complications of chemotherapy. The duration of autonomous oral alimentation was exactly the same in both groups (median, 12 + months). CONCLUSION: The results of this study suggest that 5-FU and cisplatin are not useful for patients with squamous cell carcinoma of the esophagus who have not undergone curative resection.

[Laparoscopic cholecystectomy. Technique and complications. Report of 2,665 cases].

Retrospective study of 2,665 laparoscopic cholecystectomies (LC) performed between April 1988 and December 1994 in the French technique with selective intra operative cholangiography. Obesity was present in 13% of patients, respiratory insufficiency in 4%, inflammation in 13% and common bile duct (CBD) stones in 4%. Those cases are now good indications for L.C. A conversion to laparotomy occurred in 52 cases (2%). The rate of post operative complications was 1.6%, including 24 non biliary complications with 2 death and 17 biliary ones concerning the CBD in 6 cases. Those results compare favourably with the ones of open cholecystectomy and the cost is about the half.

Pancreatic cystadenoma and cystadenocarcinoma: diagnostic value of preoperative morphological investigations.

OBJECTIVE: To find out whether preoperative morphological investigations differentiated between serous cystadenoma, mucinous cystadenoma, and cystadenocarcinoma of the pancreas. DESIGN: Multicentre retrospective study of casenotes. SETTING: 24 Adult gastroenterology units (1 private, 8 non-university teaching hospitals, and 15 university teaching hospitals) in France. SUBJECTS: 71 Patients with 74 tumours diagnosed between January 1978 and January 1988. MAIN OUTCOME MEASURES: Correlation between histological diagnosis and results of ultrasonography, computed tomography, angiography, and magnetic resonance imaging. RESULTS: 6 of 59 ultrasound scans (10%), 7 of 52 computed tomograms (13%), 0 of 18 angiograms, 1 of 12 pancreatograms (8%), and the single magnetic resonance scan correctly diagnosed the type of pancreatic tumour. Ultrasonography or computed tomography, or both, diagnosed cystadenoma (but not the type) in 26 cases (37%). "Pseudocyst" was diagnosed in 14 cases (20%). CONCLUSIONS: In contrast to other studies, our results indicate that preoperative morphological investigations are of limited value in diagnosing cystadenomas of the pancreas. In particular, their ability to differentiate between different types of cystadenoma is poor.
