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.

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.

Azygos vein aneurysm as a diagnostic pitfall. The role of thoracoscopy.

We report the case of an azygos vein aneurysm that was found intraoperatively in a 66-year-old woman followed for esophageal carcinoma. She underwent video-assisted thoracoscopy surgery (VATS) for biopsy of a mediastinal mass. This mass was diagnosed in the 2nd year of postoperative follow-up for a T2N0M0 esophageal carcinoma by computed tomography, which revealed a heterogeneous mass of ~2 cm in diameter in a retrotracheal location. Preoperative echoendoscopy demonstrated an extraesophageal lesion. A diagnostic thoracoscopy was done in order to exclude a metastatic lymph node disease.

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.

[18F]-FDG uptake in soft tissue dermatome prior to herpes zoster eruption: an unusual pitfall.

Authors report on a case of [18F]-fluorodeoxyglucose ([18F]-FDG) uptake in the soft tissue of a patient referred for [18F]-FDG coincidence detection emission tomography (CDET) in a search for recurrence of colorectal cancer. A herpes zoster eruption occurred in the same site within two days, but was spontaneously resolved. To the best of our knowledge this is the first description of a false positive [18F]-FDG result in relation to a viral infection of soft tissue. It shows that interpretation of subcutaneous foci has to be cautious in patients with or without a past history of herpes zoster even in pain-free areas and prior to skin eruption.

[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.

[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.

[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.

[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.
