Abstract
BACKGROUND AND AIMS Ampullary lesions (ALs) of the minor duodenal papilla are extremely rare. Endoscopic papillectomy (EP) is a routinely used treatment for AL of the major duodenal papilla, but the role of EP for minor AL has not been accurately studied. METHODS We identified 20 patients with ALs of minor duodenal papilla in the multicentric database from the Endoscopic Papillectomy vs Surgical Ampullectomy vs Pancreatitcoduodenectomy for Ampullary Neoplasm study, which included 1422 EPs. We used propensity score matching (nearest-neighbor method) to match these cases with ALs of the major duodenal papilla based on age, sex, histologic subtype, and size of the lesion in a 1:2 ratio. Cohorts were compared by means of chi-square or Fisher exact test as well as Mann-Whitney U test. RESULTS Propensity score-based matching identified a cohort of 60 (minor papilla 20, major papilla 40) patients with similar baseline characteristics. The most common histologic subtype of lesions of minor papilla was an ampullary adenoma in 12 patients (3 low-grade dysplasia and 9 high-grade dysplasia). Five patients revealed nonneoplastic lesions. Invasive cancer (T1a), adenomyoma, and neuroendocrine neoplasia were each found in 1 case. The rate of complete resection, en-bloc resection, and recurrences were similar between the groups. There were no severe adverse events after EP of lesions of minor papilla. One patient had delayed bleeding that could be treated by endoscopic hemostasis, and 2 patients showed a recurrence in surveillance endoscopy after a median follow-up of 21 months (interquartile range, 12-50 months). CONCLUSIONS EP is safe and effective in ALs of the minor duodenal papilla. Such lesions could be managed according to guidelines for EP of major duodenal papilla.

Abstract
Importance Understanding the learning curve of a new complex surgical technique helps to reduce potential patient harm. Current series on the learning curve of minimally invasive distal pancreatectomy (MIDP) are mostly small, single-center series, thus providing limited data. Objective To evaluate the length of pooled learning curves of MIDP in experienced centers. Design, Setting, and Participants This international, multicenter, retrospective cohort study included MIDP procedures performed from January 1, 2006, through June 30, 2019, in 26 European centers from 8 countries that each performed more than 15 distal pancreatectomies annually, with an overall experience exceeding 50 MIDP procedures. Consecutive patients who underwent elective laparoscopic or robotic distal pancreatectomy for all indications were included. Data were analyzed between September 1, 2021, and May 1, 2022. Exposures The learning curve for MIDP was estimated by pooling data from all centers. Main Outcomes and Measures The learning curve was assessed for the primary textbook outcome (TBO), which is a composite measure that reflects optimal outcome, and for surgical mastery. Generalized additive models and a 2-piece linear model with a break point were used to estimate the learning curve length of MIDP. Case mix-expected probabilities were plotted and compared with observed outcomes to assess the association of changing case mix with outcomes. The learning curve also was assessed for the secondary outcomes of operation time, intraoperative blood loss, conversion to open rate, and postoperative pancreatic fistula grade B/C. Results From a total of 2610 MIDP procedures, the learning curve analysis was conducted on 2041 procedures (mean [SD] patient age, 58 [15.3] years; among 2040 with reported sex, 1249 were female [61.2%] and 791 male [38.8%]). The 2-piece model showed an increase and eventually a break point for TBO at 85 procedures (95% CI, 13-157 procedures), with a plateau TBO rate at 70%. The learning-associated loss of TBO rate was estimated at 3.3%. For conversion, a break point was estimated at 40 procedures (95% CI, 11-68 procedures); for operation time, at 56 procedures (95% CI, 35-77 procedures); and for intraoperative blood loss, at 71 procedures (95% CI, 28-114 procedures). For postoperative pancreatic fistula, no break point could be estimated. Conclusion and Relevance In experienced international centers, the learning curve length of MIDP for TBO was considerable with 85 procedures. These findings suggest that although learning curves for conversion, operation time, and intraoperative blood loss are completed earlier, extensive experience may be needed to master the learning curve of MIDP.

Abstract
BACKGROUND Robot-assisted distal pancreatectomy (RDP) is increasingly used as an alternative to laparoscopic distal pancreatectomy (LDP) in patients with resectable pancreatic cancer but comparative multicenter studies confirming the safety and efficacy of RDP are lacking. METHODS An international, multicenter, retrospective, cohort study, including consecutive patients undergoing RDP and LDP for resectable pancreatic cancer in 33 experienced centers from 11 countries (2010-2019). The primary outcome was R0-resection. Secondary outcomes included lymph node yield, major complications, conversion rate, and overall survival. RESULTS In total, 542 patients after minimally invasive distal pancreatectomy were included: 103 RDP (19%) and 439 LDP (81%). The R0-resection rate was comparable (75.7% RDP vs. 69.3% LDP, p = 0.404). RDP was associated with longer operative time (290 vs. 240 min, p < 0.001), more vascular resections (7.6% vs. 2.7%, p = 0.030), lower conversion rate (4.9% vs. 17.3%, p = 0.001), more major complications (26.2% vs. 16.3%, p = 0.019), improved lymph node yield (18 vs. 16, p = 0.021), and longer hospital stay (10 vs. 8 days, p = 0.001). The 90-day mortality (1.9% vs. 0.7%, p = 0.268) and overall survival (median 28 vs. 31 months, p = 0.599) did not differ significantly between RDP and LDP, respectively. CONCLUSIONS In selected patients with resectable pancreatic cancer, RDP and LDP provide a comparable R0-resection rate and overall survival in experienced centers. Although the lymph node yield and conversion rate appeared favorable after RDP, LDP was associated with shorter operating time, less major complications, and shorter hospital stay. The specific benefits associated with each approach should be confirmed by multicenter, randomized trials.

Abstract
BACKGROUND The relevance of laparoscopic resection of intrahepatic cholangiocarcinoma (ICC) remains debated. The aim of this study was to compare laparoscopic (LLR) and open (OLR) liver resection for ICC, with specific focus on textbook outcome and lymph node dissection (LND). METHODS Patients undergoing LLR or OLR for ICC were included from two French, nationwide hepatopancreatobiliary surveys undertaken between 2000 and 2017. Patients with negative margins, and without transfusion, severe complications, prolonged hospital stay, readmission or death were considered to have a textbook outcome. Patients who achieved both a textbook outcome and LND were deemed to have an adjusted textbook outcome. OLR and LLR were compared after propensity score matching. RESULTS In total, 548 patients with ICC (127 LLR, 421 OLR) were included. Textbook-outcome and LND completion rates were 22.1 and 48.2 per cent respectively. LLR was independently associated with a decreased rate of LND (odds ratio 0.37, 95 per cent c.i. 0.20 to 0.69). After matching, 109 patients remained in each group. LLR was associated with a decreased rate of transfusion (7.3 versus 21.1 per cent; P = 0.001) and shorter hospital stay (median 7 versus 14 days; P = 0.001), but lower rate of LND (33.9 versus 73.4 per cent; P = 0.001). Patients who underwent LLR had lower rate of adjusted TO completion than patients who had OLR (6.5 versus 17.4 per cent; P = 0.012). CONCLUSION The laparoscopic approach did not substantially improve quality of care of patients with resectable ICC.

Abstract
This phase III trial included patients with ultra-low rectal adenocarcinoma that initially required abdominoperineal resection. The surgical decision was based on clinical tumour status after preoperative treatment. The overall sphincter-saving resection rate was 85 per cent, with 72 per cent rate of intersphincteric resection. Long-term results showed that changing the initial abdominoperineal resection indication into a sphincter-saving resection according to tumoral response is oncologically safe.

Abstract
BACKGROUND A radical left pancreatectomy in patients with pancreatic ductal adenocarcinoma (PDAC) may require extended, multivisceral resections. The role of a laparoscopic approach in extended radical left pancreatectomy (ERLP) is unclear since comparative studies are lacking. The aim of this study was to compare outcomes after laparoscopic vs open ERLP in patients with PDAC. METHODS An international multicenter propensity-score matched study including patients who underwent either laparoscopic or open ERLP (L-ERLP; O-ERLP) for PDAC was performed (2007-2015). The ISGPS definition for extended resection was used. Primary outcomes were overall survival, margin negative rate (R0), and lymph node retrieval. RESULTS Between 2007 and 2015, 320 patients underwent ERLP in 34 centers from 12 countries (65 L-ERLP vs. 255 O-ERLP). After propensity-score matching, 44 L-ERLP could be matched to 44 O-ERLP. In the matched cohort, the conversion rate in L-ERLP group was 35%. The L-ERLP R0 resection rate (matched cohort) was comparable to O-ERLP (67% vs 48%; P = 0.063) but the lymph node yield was lower for L-ERLP than O-ERLP (median 11 vs 19, P = 0.023). L-ERLP was associated with less delayed gastric emptying (0% vs 16%, P = 0.006) and shorter hospital stay (median 9 vs 13 days, P = 0.005), as compared to O-ERLP. Outcomes were comparable for additional organ resections, vascular resections (besides splenic vessels), Clavien-Dindo grade ≥ III complications, or 90-day mortality (2% vs 2%, P = 0.973). The median overall survival was comparable between both groups (19 vs 20 months, P = 0.571). Conversion did not worsen outcomes in L-ERLP. CONCLUSION The laparoscopic approach may be used safely in selected patients requiring ERLP for PDAC, since morbidity, mortality, and overall survival seem comparable, as compared to O-ERLP. L-ERLP is associated with a high conversion rate and reduced lymph node yield but also with less delayed gastric emptying and a shorter hospital stay, as compared to O-ERLP.

Abstract
BACKGROUND Intraoperative management based on thoracoscopy, prone position and two-lung ventilation could decrease the rate of postoperative pulmonary complications after esophagectomy. The aim of this study was to compare this multifaceted approach (MIE-PP) and conventional thoracotomy for Ivor Lewis procedure after a systematic laparoscopic dissection. METHODS Data from 137 consecutive patients undergoing Ivor Lewis procedures between 2010 and 2017 at two tertiary centers was analyzed retrospectively. The outcomes of patients who underwent MIE-PP (n = 58; surgeons group 1) were compared with those of patients undergoing conventional approach (n = 79; surgeons group 2). Our primary outcome was major postoperative pulmonary complications. Our main secondary outcomes were anastomotic leak, quality of resection and mortality. RESULTS Female patients were more prevalent in the MIE-PP group (p = 0.002). Other patient characteristics, cTNM staging and neoadjuvant treatment rate were not different between groups. Major postoperative pulmonary complications were significantly lower in the MIE-PP group compared to Conventional group (24 vs. 44%; p = 0.014). Anastomotic leak occurred in 31 versus 18% in MIE-PP group and Conventional groups, respectively (p = 0.103). Complete resection rate (98 vs. 95%; p = 0.303) and mean number of harvested lymph nodes (16 (4-40) vs. 18 (3-37); p = 0.072) were similar between the two groups. Postoperative mortality rates were 0 versus 2% at day 30 (p = 0.508) and 0 versus 7.6% at day 90 (p = 0.038). CONCLUSION Short-term outcomes of minimally invasive Ivor Lewis using thoracoscopy, prone position and two-lung ventilation are at least equivalent to the hybrid approach. Anastomotic leak after MIE-PP remains a major concern.

Abstract
Laparoscopic sleeve gastrectomy (LSG) has become one of the most common bariatric procedures. Even so, the gastric leak remains the most feared complication with a difficult, non-standardized treatment. The purpose of this study was to assess the feasibility of a new classification of leakage after LSG used in Montpellier University Hospital. We have studied the correlations between radiological findings and therapeutic outcome for the 20 gastric leaks. The presence of a leak was evaluated according to the day of appearance, the symptomatology, the location, severity on the CT scan, and the management. From May 2010 to September 2012, we prospectively collected data from 20 patients diagnosed with gastric leak after LSG. There were 16 women and 4 men with a mean age of 34 years old (range 21-52 years old). The fistula was diagnosed at postoperative day 28.1 days (range 3-77 days). Patients were grouped by the new classification in: 11-type I, 6-type II, 3-type III fistula, and 0-type IV. The visualization of leakage was observed for five cases (25 %). The initial surgical drainage was performed for 11 cases and the conservative treatment was preferred in 9 cases. Three cases necessitated a delayed surgical drainage after 1 week of conservative treatment. The surgical drainage was performed by laparoscopy in 12 cases and by laparotomy in 2 cases. The new CT scan classification of gastric leak could serve as a working basis for a consensus on the therapeutic management of this dreaded complication.

Abstract
BACKGROUND The surgical treatment of morbid obesity by laparoscopic adjustable gastric banding has become a "gold standard" in Europe. Currently, five types of silicone bands are used in the majority of countries performing bariatric surgery. METHODS The MIDBAND was introduced to the European market in 2000. It is placed around the stomach using the Pars Flaccida technique described by Forsell. A prospective multicentric study on 113 cases was carried out to evaluate technical feasibility, complications, and the midterm weight loss outcomes (2 years). RESULTS The percentage of excess body weight loss was 52.58% at 2 years. Perioperative mortality was nil and the complication rate was low (slippage <2%). CONCLUSION These encouraging results require longer-term studies to validate this procedure.

Abstract
BACKGROUND Good results obtained after laparoscopic sleeve gastrectomy (LSG), in terms of weight loss and morbidity, have been reported in few recent studies. Our team has designed a multicenter prospective study for the evaluation of the effectiveness and feasibility of this operation as a restrictive procedure. METHODS From January 2003 to September 2006, 163 patients (68% women) with an average age of 41.57 years, were operated on with a LSG. Indications for this procedure were morbid obese [body mass index (BMI)>40 kg/m2] or severe obese patients (BMI>35 kg/m2) with severe comorbidities (diabetes, sleep apnea, hypertension...) with high-volume eating disorders and superobese patients (BMI>50 kg/m2). RESULTS The average BMI was 45.9 kg/m2. Forty-four patients (26.99%) were superobese, 84 (51.53%) presented with morbid obesity, and 35 (21.47%) were severe obese patients. Prospective evaluations of excess weight loss, mortality, and morbidity have been analyzed. Laparoscopy was performed in 162 cases (99.39%). No conversion to laparotomy had to be performed. There was no operative mortality. Perioperative complications occurred in 12 cases (7.36%). The reoperation rate was 4.90% and the postoperative morbidity was 6.74% due to six gastric fistulas (3.66%), in which four patients (2.44%) had a previous laparoscopic adjustable gastric banding. Long-term morbidity was caused by esophageal reflux symptoms (11.80%). The percentage of loss in excessive body weight was 48.97% at 6 months, 59.45% at 1 year (120 patients), 62.02% at 18 months, and 61.52% at 2 years (98 patients). No statistical difference was noticed in weight loss between obese and extreme obese patients. CONCLUSIONS The sleeve gastrectomy seems to be a safe and effective restrictive bariatric procedure to treat morbid obesity in selected patients. LSG may be proposed for volume-eater patients or to prepare superobese patients for laparoscopic gastric bypass or laparoscopic duodenal switch. However, weight regained, quality of life, and evolution ofmorbidities due to obesity need to be evaluated in a long-term follow up.

Abstract
PURPOSE To assess the value of MRCP in the detection of biliary complications after orthotopic liver transplantation. MATERIALS AND METHODS 27 transplanted patients with suspected biliary complication underwent a total of 34 MR and direct cholangiography procedures. MRCP were reviewed by 2 independent reviewers blinded to clinical and laboratory findings. The biliary tract was divided into 7 segments, and all lesions were evaluated using this segmental anatomy. Each segment was evaluated for the presence of dilatation, stenosis and intra-ductal debris. MRCP results were compared to results frpm direct cholangiography. RESULTS 216 (98%) of 221 biliary segments could be evaluated on MRCP, with good to excellent visualization in 179 (80%) cases. Segmental analysis showed sensitivity, specificity and accuracy values of 85%, 81% and 83% for the detection of biliary stenosis, 82%, 81% and 81% for the detection of biliary dilatation, and 60%, 88% and 80% for the detection of inyraductal debris. CONCLUSION MRCP is accurate for the detection of biliary stenosis and dilatation in patients after liver transplantation and provides an alternative to direct cholangiography.

Abstract
UNLABELLED Biliary injuries after laparoscopic cholecystectomy are rare but serious. Their mortality rate can reach 9%. AIM OF THE STUDY Describe the management of biliary injuries after laparoscopic cholecystectomy in our center. PATIENTS Between January 1995 and June 2005, 27 patients (13 women, 14 men) were treated. The mean age was 53 years old (range, 18-92 years). The biliary injuries were common bile duct sections (n=16, 60%), common bile duct stenoses (n=5, 18.5%), biliary fistulas from the cystic duct (n=4, 15%), and biliary fistulas from an aberrant biliary duct (n=2, 7.5%). RESULTS Acute cholecystis was present in 40% of cases (n=11). An intraoperative cholangiography was done in 12 patients (44%). The mortality rate was 0%. Of the common bile duct sections, 43% were diagnosed during the cholecystectomy (n=7) or after the cholecystectomy within a mean of 11.2 days (n=9). Common bile duct injuries were treated in 16 cases with hepatojejunostomy and in five cases with an external biliary drain. Fistulas from the cystic duct were diagnosed within a mean 14.8 days. A fistula from an aberrant biliary duct was diagnosed during the cholecystectomy (n=1) or in the second postoperative day (n=1). Fistulas were treated with a clip on the cystic duct (n=2), an external biliary drain (n=1), a biliary endoprosthesis (n=1), and the biliary aberrant duct suture (n=2). CONCLUSION Common bile duct injuries are a serious complication because their treatment is a hepaticojejunostomy in 75% of cases.

Abstract
BACKGROUND The commonest surgical procedure for management of morbid obesity in Europe is laparoscopic adjustable gastric banding (LAGB), even though laparoscopic vertical banded gastroplasty (LVBG) is still considered to be a gold standard restrictive option in bariatric surgery. A multicenter prospective study was designed to to assess the efficacy of LVBG in terms of weight loss and complication rates for obese patients who have indications for a restrictive procedure. PATIENTS AND METHODS Two-hundred morbidly obese patients (84.5% female) with a mean age of 41 years and mean body mass index (BMI) of 43.2 kg/m(2) underwent LVBG as described by MacLean. Five trocars were placed in standard positions as per laparoscopic upper gastrointestinal surgery. A vertical gastric pouch (30 ml) was created with circular (21 or 25mm) and endolinear stapling techniques, enabling definitive separation of the two parts of the stomach. The gastric outlet was calibrated with either a polypropylene mesh (5.5 cm in length and 1cm in width) or a nonadjustable silicone band. The median follow-up period was 30 months (range, 1-72 months). RESULTS One case had to be converted to open surgery (gastric perforation) and there was one death secondary to peritonitis of unknown etiology. The morbidity rate was 24%, comprising the following complications: gastric outlet stenosis (8%); staple line leak (2.5%); food trapping (1.5%); peritonitis (1%); thrombophlebitis (1.5%); pulmonary embolism (0.5%); and gastroesophageal reflux (9%). The excess weight loss achieved was 56.7% (1 year), 68.3% (2 years), and 65.1% (3 years). CONCLUSIONS Laparoscopic vertical banded gastroplasty is an effective procedure for the surgical management of morbid obesity, especially for patients who present hyperphagia but are unable to manage the constraints of adjustable gastric banding. Laparoscopic vertical banded gastroplasty is safe, as demonstrated by an acceptable complication rate, of which gastric outlet stenosis, staple line leakage, and gastroesophageal reflux predominate.

Abstract
BACKGROUND Experience was gained management of intra-gastric migration of adjustable gastric banding. METHODS From July 1996 to January 2003, 4236 patients who underwent laparoscopic adjustable gastric banding were proposed for routine follow-up. Gastrograms were performed in case of band adjustment. Radiological controls and endoscopy were performed according to symptoms. RESULTS A total of 45 cases of band migration (1.6%) were diagnosed during follow-up. All but one of the migrated bands were removed laparoscopically either by a dissection outside the stomach or through a short gastrotomy. Mortality was 0% and morbidity 8% (n = 4). CONCLUSION The risk of an intragastric band migration remains low in the literature but could grow on account of the longer follow-up of patients. The retrieval of the band is the gold standard and must be planned promptly or delayed according to symptoms.

Abstract
AIM To evaluate the prospects of ambulatory surgery for inguinal hernia. PATIENTS AND METHODS From January 1995 to June 2001, 599 operations on inguinal hernias were performed. Patients were composed of 554 men and 45 women. The average age was 58 years (7-95). All patients were examined by their primary doctor on the first and the third day, and by the surgeon on the 10th day. RESULTS Four hundred and eighty-one patients were operated on by ambulatory surgery (80.3%). The "Tension-free" technique was carried out among 495 patients (82.6%). Loco-regional anaesthesia was used for 499 patients (83.3%). The postoperative rate of complications was 10.4% (62 patients). Only 201 patients presented postoperative painful symptomatology (33.6%), 341 a discomfort (56.9%), and 57 (10%) experienced no pain. The overall satisfaction rate was 92.9%. CONCLUSION Use of the "Tension-free" technique under loco-regional anaesthesia for inguinal hernias allows ambulatory surgery with a low rate of complications and high satisfaction for the patients.

Abstract
BACKGROUND We reviewed our experience of laparoscopic left pancreatectomy to establish the feasibility of this approach and the characteristics of the operating procedure. METHODS Thirteen patients with a mean age of 60 years were deemed for a left pancreatectomy. Preoperative diagnoses were: nine mucinous cystadenoma and one insulinoma, intraductal mucinous ectasia, chronic pancreatitis with ductal stenosis, and distal pancreatic tumor. RESULTS Operative mortality was nil. Two patients required conversion for bleeding from splenic vein injuries leading to a splenectomy in one case. The spleen was preserved in 10 cases. Postoperative course was uneventful in nine cases. Four patients experienced postoperative complications: one pancreatic fistula, two liquid cysts on the pancreatic margin, and one reoperation for bleeding from a trocar port. Length of stay ranged from 5 to 22 days. CONCLUSION These preliminary results confirm that in selected cases laparoscopic resection of the left pancreas is feasible and safe.

Abstract
Although CYP3A induction by dexamethasone has been extensively documented, its mechanism is still unclear because both the role of the glucocorticoid receptor and the ability of dexamethasone to activate the human pregnane X receptor have been questioned. In an attempt to resolve this problem, we investigated the response of CYP3A4 to dexamethasone (10 nm-100 microm) in primary human hepatocytes and HepG2 cells, using a variety of methods: kinetic analysis of CYP3A4 and tyrosine aminotransferase expression, effects of RU486 and cycloheximide, ligand binding assay, cotransfection of HepG2 cells with CYP3A4 reporter gene constructs and vectors expressing the glucocorticoid receptor, pregnane X receptor or constitutively activated receptor. In contrast to rifampicin (monophasic induction), dexamethasone produces a biphasic induction of CYP3A4 mRNA consisting of a low-dexamethasone component (nmol concentrations) of low amplitude (factor of 3-4) followed by a high-dexamethasone component (supramicromolar concentrations) of high amplitude (factor of 15-30). We show that the low-dexamethasone component results from the glucocorticoid receptor-mediated expression of pregnane X receptor and/or constitutively activated receptor which, in turn, are able to transactivate CYP3A4 in a xenobiotic-independent manner. At supramicromolar concentrations (>10 microm), dexamethasone binds to and activates pregnane X receptor thus producing the high-dexamethasone component of CYP3A4 induction. We conclude that, in contrast to the other xenobiotic inducers of CYP3A4, glucocorticoids play a dual role in CYP3A4 expression, first by controlling the expression of PXR and CAR under physiological conditions (submicromolar concentrations) through the classical glucocorticoid receptor pathway, and second by activating the pregnane X receptor under bolus or stress conditions (supramicromolar concentrations).

Abstract
UNLABELLED In this randomized, double-blinded study we sought to assess the analgesic efficacy of ropivacaine and bupivacaine in combination with sufentanil and the efficacy of ropivacaine alone after major abdominal surgery. Sixty patients undergoing major abdominal surgery received standardized general anesthesia combined with epidural thoracic analgesia. They were allocated to one of three groups: the BS group received postoperative patient-controlled epidural analgesia with 0.125% bupivacaine plus 0.5 microg/mL sufentanil; the RS group received 0.125% ropivacaine plus 0.5 microg/mL sufentanil; and the R group received 0.2% ropivacaine, with the patient-controlled epidural analgesia device set at bolus 2-3 mL and background infusion 3-5 mL/h. Visual analog scale scores were significantly lower during coughing in the BS group compared with the RS and R groups and in the RS group compared with the R group. The BS group required significantly less local anesthetic (milligrams per day) during the first three postoperative days compared with the RS and R groups, and the RS group, significantly less than the R group. No major side effects were noted in any group. We conclude that, after major abdominal surgery, thoracic epidural analgesia was more effective with bupivacaine than with ropivacaine when these two local anesthetics are used in a mixture with sufentanil. Ropivacaine alone was less effective than ropivacaine in combination with sufentanil. IMPLICATIONS After major abdominal surgery, thoracic epidural analgesia was more effective with 0.125% bupivacaine than with 0.125% ropivacaine when these two local anesthetics were used in a mixture with 0.5 microg/mL sufentanil. Ropivacaine 0.2% alone was less effective than 0.125% ropivacaine combined with sufentanil.

Abstract
The expression of three cytochromes P450 (CYP3A4, CYP2C9, and CYP2B6) was investigated in primary human hepatocyte cultures following treatment with four calcium channel modulators (CCM) of the dihydropyridine family, three antagonists (nifedipine, nicardipine, and isradipine), and one agonist (BK8644). Induction of CYP3A4 was studied by Northern blot, Western blot, and enzymatic activity. Induction began between 1 and 10 microM CCM and was dependent on the presence of dexamethasone (100 nM) in the medium. CYP3A4 mRNA accumulation started only after 16 h of treatment because pregnane X receptor (hPXR) synthesis was needed. Cotransfection experiments showed that the proximal and the distal PXR response elements of the CYP3A4 promoter and hPXR (HepG2 cells) or dexamethasone-induced hPXR (primary hepatocytes) were necessary to obtain full induction. Furthermore, glutathione S-transferase pull-down assays demonstrated that the CCM tested can act as hPXR ligands. In addition, cotransfection experiments in CV1 cells showed that these compounds failed to reverse CAR (constitutively activated receptor) inactivation by androstenol. Finally, 10 microM CCM induced both CYP2C9 and CYP2B6, strengthening the evidence that hPXR is involved in the regulation of these genes. All together, these results widen the field of hPXR activators to a new class of ligand, namely the CCM of the dihydropyridine family.

Abstract
Nocardiosis is a life-threatening infection, particularly among immunocompromised patients, which usually affects lungs, skin and central nervous system. We report a case of disseminated nocardiosis revealed by suppurative thyroiditis in a liver-kidney transplant recipient with poor nutritional status at the time of infection. Nocardia Asteroides was isolated from fine-needle aspiration material of the thyroid abscess. Clinical manifestations resolved after surgical drainage of the thyroid abscess, prolonged antibiotherapy and diminution of immunosuppressive regimen. Clinicians should be aware of this entity, as Nocardia Asteroides may need more than 5 days of culture to be isolated.

Abstract
The expression and inducibility of four CYP2C genes, including CYP2C8, -2C9, -2C18, and -2C19, was investigated in primary cultures of human hepatocytes. By the use of RNase protection assay and specific antibodies, each CYP2C mRNA and protein were quantified unequivocally. The four CYP2C mRNAs were expressed in human livers and cultured primary hepatocytes, but only the CYP2C18 protein was not detected. Compounds known to activate the pregnane X receptor (PXR) such as rifampicin, or the constitutively activated receptor (CAR) such as phenobarbital, induced CYP2C8, CYP2C9, and to a lesser extent CYP2C19 mRNAs and proteins. CYP2C18 mRNA was expressed but not inducible. The concentration dependence of CYP2C8 and CYP2C9 mRNAs in response to rifampicin and phenobarbital paralleled that of CYP3A4 and CYP2B6, the maximum accumulation being reached with 10 microM rifampicin and 100 microM phenobarbital. In contrast, dexamethasone produced maximum induction of CYP2C8 and CYP2C9 mRNAs at 0.1 microM while in these conditions neither CYP3A4 nor CYP2B6 was significantly induced. Moreover, the concentration dependence of CYP2C8 and CYP2C9 mRNAs in response to dexamethasone paralleled that of tyrosine aminotransferase. Furthermore, dexamethasone, which has been recently shown to up-regulate PXR and CAR expression through the glucocorticoid receptor, potentiated CYP2C8 and CYP2C9 mRNA induction in response to rifampicin and phenobarbital. Collectively, these results suggest the possible implication of at least three receptors in the regulation of CYP2C8 and CYP2C9 expression, i.e., glucocorticoid receptor, PXR, and/or CAR.

Abstract
The barbiturate phenobarbital induces the transcription of cytochromes P450 (CYPs) 2B through the constitutive androstane receptor (CAR; NR1I3). CAR is a member of the nuclear receptor family (NR1) mostly expressed in the liver, which heterodimerizes with retinoid X receptor (RXR) and was shown to transactivate both the phenobarbital responsive element module of the human CYP2B6 gene and the CYP3A4 xenobiotic response element. Because previous studies in rodent hepatocyte cultures have shown that the phenobarbital-mediated induction of CYP2B genes is potentiated by glucocorticoids, we examined the role of activated glucocorticoid receptor in this process. We show that submicromolar concentrations of dexamethasone enhance phenobarbital-mediated induction of CYP3A4, CYP2B6, and CYP2C8 mRNA in cultured human hepatocytes. In parallel, we observed that glucocorticoid agonists, such as dexamethasone, prednisolone, or hydrocortisone, specifically increase human car (hCAR) mRNA expression. Accumulation of hCAR mRNA parallels that of tyrosine aminotransferase: both mRNAs reach a maximum at a concentration of 100 nM dexamethasone and are down-regulated by concomitant treatment with the glucocorticoid antagonist RU486. Moreover, the effect of dexamethasone on hCAR mRNA accumulation appears to be of transcriptional origin because the addition of protein synthesis inhibitor cycloheximide has no effect, and dexamethasone does not affect the degradation of hCAR mRNA. Furthermore, dexamethasone increases both basal and phenobarbital-mediated nuclear translocation of CAR immunoreactive protein in human hepatocytes. The up-regulation of CAR mRNA and protein in response to dexamethasone explains the synergistic effect of this glucocorticoid on phenobarbital-mediated induction of CYP2B genes and the controversial role of the glucocorticoid receptor on phenobarbital-mediated CYP gene inductions.

Abstract
The marked impairment of hepatic drug metabolism during inflammation and infections has been known for many years and shown to result from down-regulation of cytochrome P450s (CYP) by cytokines. However, the mechanism of this repression is unknown. Using primary cultures of human hepatocytes, we show here that interleukin-6 (IL-6) rapidly and markedly decreases the expression of PXR (pregnane X receptor) and CAR (constitutively activated receptor) mRNAs, but does not affect the levels of dioxin receptor and glucocorticoid receptor mRNA. In parallel, IL-6 decreases both rifampicin- and phenobarbital-mediated induction of CYP2B6, CYP2C8, CYP2C9, and CYP3A4. As the transcriptional activity of PXR and CAR is not affected by IL-6 in cell-based reporter assays, our data suggest that the loss of CYP2 and CYP3 inducibility results from the negative regulation of PXR and CAR gene expression by this cytokine.

Abstract
In this report we show that submicromolar concentrations of dexamethasone enhance pregnane X receptor (PXR) activator-mediated CYP3A4 gene expression in cultured human hepatocytes. Because this result is only observed after 24 h of cotreatment and is inhibited by pretreatment with cycloheximide, we further investigated which factor(s), induced by dexamethasone, might be responsible for this effect. We report that dexamethasone increases both retinoid X receptor-alpha (RXRalpha) and PXR mRNA expression in cultured human hepatocytes, whereas PXR activators such as rifampicin and clotrimazole do not. Accumulation of RXRalpha and PXR mRNA reaches a maximum at a concentration of 100 nM dexamethasone after treatment for 6 to 12 h and is greatly diminished by RU486. A similar pattern of expression is observed with tyrosine aminotransferase mRNA. Moreover, the effect of dexamethasone on PXR mRNA accumulation seems to be through direct action on the glucocorticoid receptor (GR) because the addition of cycloheximide has no effect, and dexamethasone does not affect the degradation of PXR mRNA. Furthermore, dexamethasone induces the accumulation of a RXRalpha-immunoreactive protein and increases the nuclear level of RXRalpha:PXR heterodimer as shown by gel shift assays with a CYP3A4 ER6 PXRE probe. This accumulation of latent PXR and RXRalpha in the nucleus of hepatocytes explains the synergistic effect observed with dexamethasone and PXR activators together on CYP3A4 induction. These results reveal the existence of functional cross talk between the GR and PXR, and may explain some controversial aspects of the role of the GR in CYP3A4 induction.

Abstract
OBJECTIVE To analyse retrospectively the results of one-stage laparoscopic treatment for common bile duct stones in 19 surgical centers in France. PATIENTS From January 1991 to July 1996, 612 patients with choledocholithiasis underwent laparoscopic treatment. RESULTS Overall duct clearance was obtained in 489 of the 612 patients (80%): through the cystic duct in 222 of 380 patients (58.4%), by secondary choledochotomy (after unsuccessful transcystic duct extraction) in 77 of 96 (80%), and in 190 of 232 (82 %) by primary choledochotomy. The overall duct clearance rate increased from 65% in 1991 to 84% in 1996. The use of the choledochotomy approach increased from 43% in 1991 to 69% in 1996 (P<0.01), due to a substantial increase in primary choledochotomy. In contrast, the use of the transcystic approach decreased from 57% to 31% (P<0.01). The mean time for surgery was shorter for cystic duct exploration than for primary choledochotomy (101+/-51 vs. 155+/-62 min, P<0.0001). The mean hospital stay decreased from 7.7+/-3.6 days in 1991 to 4.1+/-2 days in 1996 (P<0.001). The main biliary complications were related to biliary drainage (2,8%) and retained stones (3.1%). CONCLUSION This study confirms that laparoscopy is a good alternative with a low complication rate, a short hospital stay, and is an effective and safe option for the management of common bile duct stones.

Abstract
OBJECTIVE The aim of this prospective study was to assess the feasibility and postoperative advantages of the laparoscopic-assisted elective colectomy for diverticular disease. PATIENTS AND METHODS From january 1989 to december 1997, among the 114 patients electively operated on for diverticulitis, 56 patients were treated by laparoscopic approach. Evaluated parameters included: gender, age, weight, size, ASA score, operating time, duration of hospital stay, of analgesic treatment, and of postoperative ileus, morbidity and mortality rate. RESULTS The study group consisted of 35 women and 21 men. Mean age was 59 years (34-81 years); 29 patients were ASA 1 and 27 ASA 2. Overall postoperative mortality rate was 0% and morbidity rate 16% (n = 9). There were no complications directly related to laparoscopic technique. The conversion rate was 14% (n = 8). Mean operating time was 300 min (200-600 min). Mean duration of postoperative ileus was 2.4 days. Mean duration of hospital stay was 9.4 days. CONCLUSION This study demonstrates the feasibility of elective laparoscopic-assisted colonic resection for diverticular disease in more than 80% of cases with a postoperative morbidity and mortality rate comparable to those of conventional surgery.

Abstract
BACKGROUND The persistence and migration of donor leukocytes has been well established, but cellular kinetics immediately after revascularization and the potential relevance of these different lymphocyte populations to spontaneous tolerance remain unclear. During the early hours of revascularization, there is a transitory "congestion" of the liver graft, which is evidence of an early phase that we have termed "first cellular contact." METHODS We have carried out by flow cytometry a prospective comparative study of the peak kinetics of lymphocyte subpopulations contained in: (a) peripheral blood and liver grafts at the time of multi-organ extraction from 14 brain-dead donors, (b) recipient peripheral blood before transplantation, and (c) recipient peripheral blood and liver grafts after (t=2 h) declamping and vascularization of the liver graft. RESULTS Before transplantation, the liver grafts contained large numbers of natural killer (NK) and NK-like cells with early lymphocyte activation. Immediately after revascularization, there was an influx of recipient NK and NK-like cells into the liver. CONCLUSIONS NK and CD3+CD56+ (NK-like) cells flooding into the liver graft immediately after revascularization could rapidly destroy allogeneic cells. However, spontaneous tolerance and the persistence of donor lymphocytes after orthotopic liver transplant could be a result of donor TCRalphabeta NK1.1 liver graft lymphocytes, which may be involved in the destruction of CD8+ T lymphocytes that would have received the apoptosis signal, and to NK and NK-like cell inhibition via inhibitory NK receptors. The decrease in gammadelta T lymphocytes in the two compartments suggests a mechanism of recirculation and capture in other lymphoid organs.

Abstract
Eletriptan (Relpax) is a novel 5-hydroxytryptamine (serotonin)(1D/1B) agonist currently in development for the acute treatment of migraine. The aim of this work was to evaluate the relative induction potency of eletriptan in vitro compared with well characterized cytochrome P-450 (CYP) inducers with primary cultures of human hepatocytes and to relate this to the situation in vivo. Eletriptan was a weak inducer of CYP3A4 protein and cyclosporin A oxidation in four of the six cultures used, whereas rifampicin was a potent inducer in all cultures. Induction was concentration dependent and not detectable at eletriptan concentrations of 5 microM and lower. The amplitude of the increase in CYP3A4 protein and activity by 25 microM eletriptan was significantly lower, with a mean of 19 (P =.0015) and 26% (P =.0002), respectively, of that observed in response to 25 microM rifampicin. CYP2A6, a protein with minor pharmacological implication, also was induced by eletriptan and rifampicin in two cultures but was not detected in the others. The levels of other CYP proteins, including CYP1A2, CYP2C9, CYP2C19, CYP2D6, and CYP2E1, were not affected by eletriptan. Because the maximum blood concentration of eletriptan in humans after a therapeutic dose (maximum 80 mg) is 0.5 microM, the in vitro model would predict no clinically significant induction of CYP3A4 protein in vivo. This has been confirmed subsequently in a clinical study, with 6beta-hydroxycortisol/cortisol ratios as marker of CYP3A4 activity. Eletriptan is therefore not an inducer of CYP3A4 at clinical doses.

Abstract
OBJECTIVE The objective of this study was to describe the complications specifically related to orthotopic liver transplantation (OLT) with preservation of the inferior vena cava and to their therapeutic management. This preservation technique has considerably influenced the surgical phases of liver transplantation, increasing hepatectomy time and modifying the number of vascular anastomoses. METHODS Our retrospective multicentric study, based on data from 1361 adult patients that had undergone orthotopic liver transplantation with preservation of the inferior vena cava in France between 1991 and 1997, analyzed the concomitant surgical complications. Type of cavo-caval anastomosis performed (piggyback, end-to-side, or side-to-side), use of a temporary portacaval anastomosis, technique-related complications, and mortality, were investigated. RESULTS Cavo-caval anastomosis was side-to-side in 50.6% of cases (n=689), piggyback in 42.7% (n=582), and end-to-side in 6.6% (n=90). In total, 882 temporary portacaval anastomosis were carried out. Fifty-five patients presented with one or more complications related to the preservation of the inferior vena cava technique; i.e., overall morbidity was 4.1% (55/1361). Overall mortality was 0.7% (10/1361). Mortality rate for patients who presented with surgical complication was 18%. A total of 64 complications were recorded: 57 (89%) were in the perioperative or immediate postoperative period and 7 (11%) were postoperative. CONCLUSIONS These retrospective, descriptive results show significant advantages in favor of side-to-side anastomosis in terms of vascular complications. Certain factors should be evaluated specifically at pretransplant assessment to prevent certain serious complications; principally, these are anatomic factors of the recipient (inferior vena cava included in segment I, anatomic abnormalities of the inferior vena cava) and graft size. Depending on these factors, surgeons must be able to adapt the orthotopic liver transplantation, either before or during orthotopic liver transplantation, preferring the standard technique.

Abstract
BACKGROUND/AIMS Alcoholic cirrhosis remains a controversial indication for liver transplantation, mainly because of ethical considerations related to the shortage of donor livers. The aim of this study was to review experience to date, focusing on survival rates and complications, and the effect of alcohol relapse on outcome and alterations in marital and socioprofessional status. METHODS The results for 53 patients transplanted for alcoholic cirrhosis between 1989 and 1994 were compared with those for 48 patients transplanted for non-alcoholic liver disease. The following variables were analysed: survival, rejection, infection, cancer, retransplantation, employment and marital status, alcoholic recurrence. The same variables were compared between alcohol relapsers and non-relapsers. RESULTS Recovery of employment was the only significantly different variable between alcoholic (30%) and non-alcoholic patients (60%). Two factors influenced survival in the absence of alcohol recidivism: age and abstinence before transplantation. For all other variables, there were no differences between alcoholic and non-alcoholic patients, and, within the alcoholic group, between relapsers and non-relapsers. The recidivism rate was 32%. CONCLUSION The data indicate that liver transplantation is justified for alcoholic cirrhosis, even in cases of recidivism, which did no affect survival and compliance with the immunosuppressive regimen. These good results should help in educating the general population about alcoholic disease.

Abstract
UNLABELLED We assessed the role of vasopressin (VP) for the hemodynamic response to pneumoperitoneum in pigs. Four groups of anesthetized pigs were investigated. Nine pigs were intraabdominally insufflated with CO2 and eight were intraabdominally insufflated with argon; eight pigs received an i.v. injection of 1 mg/kg SR 49059, a VP antagonist, before CO2 insufflation; and six pigs received SR 49059 alone. Hemodynamics, plasma concentrations of VP and vasoactive hormones, and Paco2 were measured. Data were analyzed by using analysis of variance, Student's t-test, and Mann-Whitney U-test. Five minutes after insufflation, changes in systemic vascular resistance (SVR) were significantly correlated with changes in VP (r = 0.72; P = 0.005) but not with changes in epinephrine, norepinephrine, renin activity, or Paco2. SVR increased during CO2 insufflation but not during argon insufflation or CO2 insufflation with a preceding infusion of SR 49059. The SR 49059 injection itself resulted in increases in heart rate and cardiac output and decreases in blood pressure and SVR. We conclude that, during CO2 pneumoperitoneum in pigs, absorbed CO2 initiates a pathophysiological process that stimulates VP release. Hence, VP most likely plays a key role in the hemodynamic response to a CO2-induced pneumoperitoneum. IMPLICATIONS Intraabdominal insufflation of CO2 is associated with hemodynamic and hormonal changes. Investigating CO2 and argon-insufflated pigs and using a vasopressin antagonist, we found that CO2 insufflation released vasopressin, which, in turn, induced hemodynamic perturbances.

Abstract
OBJECTIVE To find out which factors influence the development of delayed gastric emptying (DGE) after pancreaticoduodenectomy with pancreaticogastrostomy. DESIGN Prospective clinical study. SETTING University hospital, France. SUBJECTS 88 patients of 103 consecutive patients who had had pancreaticoduodenectomies, November 1991-November 1997. INTERVENTIONS Whipple resection, and parenteral and enteral nutrition. MAIN OUTCOME MEASURES Mortality, morbidity, and development of DGE (defined as the need for a postoperative nasogastric tube for 10 days or longer). RESULTS One patient died, and 44 developed postoperative complications. 36 patients (41%) developed DGE in 21 of whom (58%, 24% of the total) it was in isolation, with no other complication; and 52 (59%) did not. There were significant differences between those who developed DGE and those who did not: 30 men (83%) compared with 6 women (17%) developed DGE compared with 32 (62%) and 20 (38%) (p = 0.03;); 15 (42%) developed a complication as well as DGE compared with 8 (15%) (p = 0.005); 10(28%) who developed DGE required reoperation compared with 4(8%) (p = 0.011); mean (SD) hospital stay was 30(12) days among those with DGE compared with 17 (5) days (p= 0.0001); and their mean (SD) serum protein concentration on day 1 was 46 (1) compared with 51 (7) g/L (p=0.01). Multivariate analysis showed that three factors independently influenced the development of DGE: sex (p = 0.01), the need for reoperation (p = 0.03) and the mean serum protein concentration on day 1 (p = 0.04). CONCLUSION Postoperative complication and the need for reoperation remain the most common factors linked to the development of DGE. However, in a quarter of patients DGE was not associated with any postoperative complication.

Abstract
The true incidence of epiphrenic esophageal diverticulum is unknown. Traditionally, diverticulectomy via a left thoracic approach has represented the gold standard. Trans-hiatal esophageal dissection under laparoscopy is feasible, but has not, to our knowledge, been applied before in the treatment of epiphrenic esophageal diverticulum.

In 4 patients the type of tumour was not known. MAIN OUTCOME MEASURE Resectability, mortality and recurrence. RESULTS More men had benign or in situ tumours [48/61 (79%) compared with 28/46 (61%), p = 0.054]. Pancreatitis was more common among benign than malignant tumours [34/61 (58%) compared with 21/46 (46%), p = 0.33]. In group I, 39 patients had diabetes. A total of 107 patients were operated on: pancreaticoduodenectomy (n = 54, 50%), distal pancreatectomy (n = 25, 23%), total pancreatectomy (n = 4,4%), bypass (n = 2,2%). The type of resection was not mentioned in 22 records (21%). Four patients were not operated on because of their poor general condition. The resectability rate was 98% (105/107). Eleven patients had died at the time of publication. Hospital mortality rate was 3% (n = 3), mainly because 2 of the 4 who had total pancreatectomy died. With a median follow-up of 37 months, recurrence was 5% (n = 5). CONCLUSION Intraductal papillary mucinous tumours of the pancreas are well known distinctive pancreatic tumours that are usually intraductal but may develop into invasive carcinoma. They should be resected, and have a good prognosis and low recurrence rate.

Abstract
AIMS/BACKGROUND We report the discovery of associated metastatic subcutaneous and metastatic diaphragmatic nodules on the needle track after fine-needle biopsy aspiration under echography, which has not yet been reported in the literature. METHODS A 35-year-old man with non-replicating hepatitis B virus presented with a tumor that suggested hepatocarcinoma with cirrhosis. A diagnostic needle biopsy was carried out before surgery. Twelve months later, he presented with a series of four continuous metastatic diaphragmatic nodules on the inner wall lining the needle track. Surgery was performed, followed by external radiation (40 Gy). CONCLUSIONS The risk of seeding following fine-needle biopsy aspiration of hepatocellular carcinoma can no longer be considered negligable. The real risk is probably underestimated. Even for biopsy of lesions localized to the inferior part of the liver, diaphragmatic seeding is possible. This seeding necessitates surgical resection, increasing the therapeutic morbidity of hepatocellular carcinomas. We believe that in cases where investigation of a small hepatic tumor suggests a hepatocellular carcinoma that could be resected, or for candidate patients for liver transplantation. one should not puncture the tumor. If this diagnostic biopsy is essential, then the needle track could be resected upon surgery, after cutaneous external tattooing.

Abstract
AIMS/BACKGROUND The anatomic structure of the liver suggests that it is a place of intense trafficking between intra-hepatic and peripheral blood compartment leukocytes. Furthermore, the liver contains a large number of passenger leukocytes that may play a role in the appearance of donor-type microchimerism after transplantation. In this study, we aimed to define the principal lymphocyte sub-populations contained in donor peripheral blood and liver grafts and in normal liver removed during minimally invasive surgery. METHODS Liver biopsies were taken at the time of vascular clampage during liver extraction from donors in a brain dead state (GI: n=14). Normal liver biopsies were removed during minimaly invasive surgery (GII: n= 10). RESULTS We observed evidence of the presence of lymphocytic activation associated with the two major CD8+ lymphocyte and natural killer (NK) cell populations in the two groups, with a significant increase in TCRgammadelta-bearing lymphocyte receptors between normal liver and the liver graft. CONCLUSIONS The presence of activated leukocytes in the graft could have a fundamental role in induction of peripheral tolerance. This activation could be the result of a basic immunological response linked to the interaction of T cells and NK cells, and of secondary activation due to stress and the conditions necessary for organ removal from donors in a brain dead state.

Abstract
BACKGROUND The advantages of pancreatogastrostomy over pancreatojejunostomy after pancreaticoduodenectomy are still debated. This study analyses the results of pancreatogastrostomy to identify factors that could influence immediate outcome. METHODS During a 10-year period, 160 consecutive patients underwent a pancreatogastrostomy. There were 109 men (68 per cent) and 51 women (32 per cent) with a mean(s.d.) age of 59(10) (range 22-82) years; 27 patients were older than 70 years. The following parameters were assessed: mortality rate, morbidity, reasons for reoperation, length of hospital stay, duration of nasogastric tube and drainage. RESULTS Hospital mortality rate was 3 per cent; overall morbidity rate was 30 per cent. The reoperation rate was 12 per cent, mainly because of bleeding at the pancreatic margin. Delayed gastric emptying occurred in 36 patients. The overall rate of pancreatic fistula was 2.5 per cent. Age, sex, indications for pancreatoduodenectomy, and the texture of the pancreatic remnant did not influence the occurrence of pancreatic fistula or delayed gastric emptying. CONCLUSION This study confirmed that pancreatogastrostomy is a safe procedure with low mortality and morbidity rates.

Abstract
BACKGROUND The aim of this experimental study was to evaluate the risk of tumor recurrence after laparoscopic cecal resection (LCR) of colonic carcinoma in the rat. METHODS The experimental cancer consisted of one million cells (DHK/K12), incorporated in an extracellular matrix, placed and secured to the cecal serosa in 110 BD9 rats. Four weeks later, all animals were reoperated through a laparotomy to control tumor growth, and animals with diffuse carcinomatosis were excluded. Eligible animals were randomized either to laparoscopic cecal resection (group LCR, n = 10), to open resection (group OCR, n = 13), or to a control group without resection (group C, n = 13). Resection was always considered as macrocopically complete. All animals were killed 4 weeks after the resection to determine the tumor recurrence and quantify carcinomatosis. RESULTS We noted diffuse carcinomatosis in 70% of rats in groups C and LCR versus 23% in group OCR (p = 0.038). For tumors noted as S- (not extending outside the serosa), diffuse carcinomatosis was observed in all animals of group C (3 of 3), in 6 of 8 in group LCR, and 0 of 6 in group OCR (p = 0.004). The rate of port site or incisional metastases was not significantly different between groups. CONCLUSIONS These preliminary results demonstrated the deleterious impact of the laparoscopy for resection of large bowel malignancy. LCR increased significantly the incidence of a diffuse carcinomatosis even when performed for locally noninvasive tumors (S-).

Abstract
BACKGROUND A high incidence of serum monoclonal immunoglobulins (mIgs) has been described after solid organ transplantation. For transplant recipients, the prevalence of posttransplant lymphoproliferative disorders (PTLDs) has been reported to be between 2% and 6%. The relationship between the finding of serum mIg in transplant recipients and the subsequent development of PTLDs is not clearly documented. METHODS We retrospectively analyzed all cases of mIg and PTLD that occurred in 86 liver transplant recipients who survived more than 3 months. Patients were characterized by protein electrophoresis, immunofixation electrophoresis, pre- and post-liver transplantation Epstein-Barr virus (EBV) serology, EBV presence in lymphoproliferative tissues by in situ hybridization, type of infection episodes, rejection episodes, and immunosuppressive treatment. RESULTS Thirty-eight patients (44%) had abnormal immunofixation electrophoresis with an electrophoretic Ig peak. Twelve patients had a polyclonal Ig peak, and 26 patients had mIgs (30%). These 26 patients were divided into two groups: 13 patients had a transient mIg peak with a mean delay for normalization of electrophoresis of 2 months, and 13 patients had a permanent mIg peak. No correlation could be demonstrated between the appearance of abnormal banding and indications for transplantation, age of patients, and acute rejection rate. There was a strong correlation between occurrence of viral infections and presence of permanent mIg. Three patients with permanent mIg (23%) developed PTLD and died. CONCLUSIONS We concluded that the prevalence of mIg after liver transplantation was 30%. Viral infections increase the risk of developing mIg. Persistence of mIg beyond 7 months may be regarded as prelymphomas necessitating a careful follow-up in these patients.
