RESUMEN
BACKGROUND: Few studies have assessed changes in antihypertensive and lipid-lowering therapy after bariatric surgery. The aim of this study was to assess the 6-year rates of continuation, discontinuation or initiation of antihypertensive and lipid-lowering therapy after bariatric surgery compared with those in a matched control group of obese patients. METHODS: This nationwide observational population-based cohort study used data extracted from the French national health insurance database. All patients undergoing gastric bypass or sleeve gastrectomy in France in 2009 were matched with control patients. Mixed-effect logistic regression models were used to analyse factors that influenced discontinuation or initiation of treatment over a 6-year interval. RESULTS: In 2009, 8199 patients underwent primary gastric bypass (55·2 per cent) or sleeve gastrectomy (44·8 per cent). After 6 years, the proportion of patients receiving antihypertensive and lipid-lowering therapy had decreased more in the bariatric group than in the control group (antihypertensives: -40·7 versus -11·7 per cent respectively; lipid-lowering therapy: -53·6 versus -20·2 per cent; both P < 0·001). Gastric bypass was the main predictive factor for discontinuation of therapy for hypertension (odds ratio (OR) 9·07, 95 per cent c.i. 7·72 to 10·65) and hyperlipidaemia (OR 11·91, 9·65 to 14·71). The proportion of patients not receiving treatment at baseline who were subsequently started on medication was lower after bariatric surgery than in controls for hypertension (5·6 versus 15·8 per cent respectively; P < 0·001) and hyperlipidaemia (2·2 versus 9·1 per cent; P < 0·001). Gastric bypass was the main protective factor for antihypertensives (OR 0·22, 0·18 to 0·26) and lipid-lowering medication (OR 0·12, 0·09 to 0·15). CONCLUSION: Bariatric surgery is associated with a good discontinuation of antihypertensive and lipid-lowering therapy, with gastric bypass being more effective than sleeve gastrectomy.

Complications related to energy sources in the operating room are not well-recognized or published, despite occasionally dramatic consequences for the patient and the responsible surgeon. The goal of this study was to evaluate the risks and consequences related to use of energy sources in the operating room. PATIENTS AND METHODS: Between 2009 and 2015, 876 adverse events related to health care (AERHC) linked to energy sources in the operating room were declared in the French experience feedback data base "REX". We performed a descriptive analysis of these AERHC and analyzed the root causes of these events and of the indications for non-elective repeat operations, for each energy source. RESULTS: Five different energy sources were used, producing 876 declared AERHC: monopolar electrocoagulation: 614 (70%) AERHC, advanced bipolar coagulation (thermofusion): 137 (16%) AERHC, ultrasonic devices: 69 (8%) AERHC, traditional bipolar electrocoagulation: 32 AERHC, and cold light: 24 AERHC. The adverse events reported were skin burns (27.5% of AERHC), insulation defects (16% of AERHC), visceral burns or perforation (30% of AERHC), fires (11% of AERHC), bleeding (7.5% of AERHC) and misuse or miscellaneous causes (8% of AERHC). For the five energy sources, the root causes were essentially misuse, imperfect training and/or cost-related reasons regarding equipment purchase or maintenance. One hundred and forty-six non-elective procedures (17% of AERHC) were performed for complications related to the use of energy sources in the operating room. CONCLUSION: This study illustrates the risks related to the use of energy sources on the OR and their consequences. Most cases were related to persistent misunderstanding of appropriate usage within the medical and paramedical teams, but complications are also related to administrative decisions concerning the purchase and maintenance of these devices.

BACKGROUND: Lifelong medical follow-up is mandatory after bariatric surgery. The aim of this study was to assess the 5-year follow-up after bariatric surgery in a nationwide cohort of patients. METHODS: All adult obese patients who had undergone primary bariatric surgery in 2009 in France were included. Data were extracted from the French national health insurance database. Medical follow-up (medical visits, micronutrient supplementation and blood tests) during the first 5 years after bariatric surgery was assessed, and compared with national and international guidelines. RESULTS: Some 16 620 patients were included in the study. The percentage of patients with at least one reimbursement for micronutrient supplements decreased between the first and fifth years for iron (from 27.7 to 24.5 per cent; P < 0.001) and calcium (from 14·4 to 7·7 per cent; P < 0·001), but increased for vitamin D (from 33·1 to 34·7 per cent; P < 0·001). The percentage of patients with one or more visits to a surgeon decreased between the first and fifth years, from 87·1 to 29·6 per cent (P < 0·001); similar decreases were observed for visits to a nutritionist/endocrinologist (from 22·8 to 12·4 per cent; P < 0·001) or general practitioner (from 92·6 to 83·4 per cent; P < 0·001). The mean number of visits to a general practitioner was 7·0 and 6·1 in the first and the fifth years respectively. In multivariable analyses, male sex, younger age, absence of type 2 diabetes and poor 1-year follow-up were predictors of poor 5-year follow-up. CONCLUSION: Despite clear national and international guidelines, long-term follow-up after bariatric surgery is poor, especially for young men with poor early follow-up.

Drug-induced adverse effects are one of the main avoidable causes of hospitalization in older people. Numerous lists of potentially inappropriate medications for older people have been published, as national and international guidelines for appropriate prescribing in numerous diseases and for different age categories. The present review describes the general rules for an appropriate prescribing in older people and summarizes, for the main conditions encountered in older people, medications that are too often under-prescribed, the precautions of use of the main drugs that induce adverse effects, and drugs for which the benefit to risk ratio is unfavourable in older people. All these data are assembled in educational tables designed to be printed in a practical pocket format and used in daily practice by prescribers, whether physicians, surgeons or pharmacists.

INTRODUCTION: Prostate-specific antigen (PSA) testing is high in France. The aim of this study was to estimate their frequency and those of biopsy and newly diagnosed cancer (PCa) according to the presence or absence of treated benign prostatic hyperplasia (BPH). PATIENTS AND METHODS: This study concerned men 40 years and older covered by the main French national health insurance scheme (73 % of all men of this age). Data were collected from the national health insurance information system (SNIIRAM). This database comprehensively records all of the outpatient prescriptions and healthcare services reimbursed. This information are linked to data collected during hospitalisations. RESULTS: The frequency of men without diagnosed PCa (10.9 millions) with at least one PSA test was very high in 2011 (men aged 40 years and older: 30 %, 70-74 years: 56 %, 85 years and older: 33 % and without HBP: 25 %, 41 % and 19 %). Men with treated BPH totalized 9 % of the study population, but 18 % of the men with at least one PSA test, 44 % of those with at least one prostate biopsy and 40 % of those with newly managed PCa. Over a 3-year period, excluding men with PCa, 88 % of men with BPH had at least one PSA test and 52 % had three or more PSA tests versus 52 % and 15 % for men without BPH. One year after PSA testing, men of 55-69 years with BPH more frequently underwent prostate biopsy than those without BPH (5.4 % vs 1.8 %) and presented PCa (1.9 % vs 0.9 %). CONCLUSIONS: PSA testing frequencies in France are very high even after exclusion of men with BPH, who can be a group with more frequent managed PCa. LEVEL OF EVIDENCE: 4.

BACKGROUND: Surgical resection of pancreatic metastasis (PM) is the only reported curative treatment for renal cell carcinoma. However, there is currently little information regarding very long-term survival. The primary objective of this study was to determine the 10-year survival of this condition using the largest surgical series reported to date. METHODS: Between May 1987 and June 2003, we conducted a retrospective study of 62 patients surgically treated for PM from renal cell carcinoma at 12 Franco-Belgian surgical centers. Follow-up ended on May 31, 2012. RESULTS: There were 27 male (44 %) and 35 female (56 %) patients with a median age of 54 years [31-75]. Mean disease-free interval from resection of primary tumor to reoperation for pancreatic recurrence was 9.8 years (median 10 years [0-25]). During a median follow-up of 91 months [12-250], 37 recurrences (60 %) were observed. After surgical resection of repeated recurrences, overall median survival time was 52.6 months versus 11.2 months after nonoperative management (p = 0.019). Cumulative 3-, 5-, and 10-year overall survival (OS) rates were 72, 63, and 32 %, respectively. The corresponding disease-free survival rates were 54, 35, and 27 %, respectively. Lymph node involvement and existence of extrapancreatic metastases before PM were associated with poor overall survival. CONCLUSIONS: Aggressive surgical management of single or multiple PM, even in cases of extrapancreatic disease, should be considered in selected patients to allow a chance of long-term survival.

BACKGROUND: Several studies seem to indicate at least a 2-fold increase in bile duct injuries (BDI) since the inception of laparoscopic cholecystectomy. Moreover, injuries seem to be more proximal, seem to be revealed earlier, are expressed by leaks more often than by strictures, are repaired more frequently by nonspecialists (either during the index operation or soon after), and appear to be more often associated with loss of substance and ischemia. The plethora of prior classifications probably attests to the evolving clinical spectrum, the mounting wealth of ever-increasing diagnostic methods, and an acknowledgment of insufficiencies or lack of data in earlier classification reports. Previous attempts at uniformity remain incomplete. The purpose of this study was to devise a nominal classification, combining all existing classification items, taking into account the changing pattern of BDI. METHODS: Extensive bibliographic research, analysis of each category within the individual classifications combined into one uniform classification. RESULTS: Fifteen classifications were retained. All items were integrated into the European Association for Endoscopic Surgery (EAES) classification, using semantic connotations, grouped in three easy-to-remember categories, A (for anatomy), To (for time of), M (for mechanism): (1) the anatomic characteristics of the injury: NMBD for non-main bile duct or MBD for main bile duct (followed by a number 1-6, corresponding to the anatomic level on the MBD), followed by Oc (for occlusion) or D (division), P (partial) or C (complete), LS (loss of substance), VBI (vasculobiliary injury in general), and whenever known, the vessel; (2) time of detection: Ei (early intraoperative), Ep (early postoperative) or L (late); and (3) mechanism of injury: Me (mechanical) or ED (energy-driven). CONCLUSIONS: The EAES composite, all-inclusive, nominal classification ATOM (anatomic, time of detection, mechanism) should allow combination of all information on BDI, irrespective of the original classification used, and thus facilitate epidemiologic and comparative studies; indicate simple, appropriate preventive measures; and better guide therapeutic indications for iatrogenic BDI occurring during cholecystectomy.

PURPOSE: This was a prospective quality-of-life (QoL) assessment of gastrointestinal symptoms before laparoscopic Nissen fundoplication and during the 6-year postoperative follow-up. METHODS: Over a 15-month period, 35 consecutive patients with gastroesophageal reflux disease (GERD) underwent surgery after failure of medical treatment with proton pump inhibitors. QoL was assessed using the Gastrointestinal Quality of Life Index (GIQLI) preoperatively, and at 3, 6, 12, 24, 48 and 72 months postoperatively. RESULTS: The preoperative GIQLI score was lower than the 'normal' score (126 points), as were the scores overall and for each dimension (social integration, physical function, emotions and gastrointestinal symptoms; all P<0.001). Also, although the GIQLI increased significantly (P<0.0001) at 3, 6, 12, 24, 48 and 72 months, it remained below normal (P<0.01). The symptom score also remained below that of the normal population (57 vs 67; P<0.0001), while the percentages of patients with abdominal pain, dysphagia, modified eating habits and belching decreased non-significantly. However, GERD symptoms were significantly reduced (51% vs 4%; P=0.01), although 20% of patients started taking proton pump inhibitors again during the follow-up period. Surgery eliminated 50% of the dysphagia symptoms reported preoperatively and, after 6 years, only 8% of patients still complained of dysphagia. CONCLUSION: Patients who undergo surgery after failure of medical treatment for GERD can expect an improved QoL, although they may not be able to achieve normal levels. Preoperative symptoms should be carefully recorded in order to better inform patients of the expected outcome following surgery.

INTRODUCTION: The prevention or the management of digestive fistulae may be performed by using an external wrap of collagen of animal origin. To evaluate this treatment, an experimental study creating a hole in the colon of pig covered by a resorbable collagen belt was performed. Results are very interesting and collagen wrap is very well tolerated by the colon wall. BACKGROUND: Digestive perforations, whether colorectal, jejunal, esophageal, or biliodigestive, are common emergency situations and can threaten the patient's condition or extend their hospital stay. The evolution of biomaterials of animal origin, and the biocompatibility proven after some human surgical procedures, have led our team to propose an experimental study in a pig model to treat colic perforation by positioning a resorbable bilayer collagen band of bovine origin over the area of an experimental hole. MATERIALS/METHODS: A first group of 10 pigs was operated upon, and a 1 cm2 hole was experimentally created in the distal part of the colon. Then, a belt of resorbable collagen sponge joined to a collagen film, from bovine origin, was placed and fixed around the outer part of the colon to cover the fistula without closing the hole by sutures. After an average of two weeks, all the animals were sacrificed. The abdominal cavity was examined in a macroscopic and microscopic manner. A second group of 10 pigs was tested under a different protocol to assess the efficiency of the bowel wrap prosthesis in a septic field. RESULTS: In the first group of pigs, there were no complications during the procedures. The mortality rate was zero during this period. No pig was operated on urgently to manage an acute complication. The complication rate was 10% due to one wound infection. The macroscopic examinations of the explanted colon articles didn't find any stricture under the prosthesis location for the 10 pigs. Local smooth adhesions were noted in 7 pigs (70%). Among the second group of pigs, the mortality rate was 10% due to a myocardial infarction during the period of peritonitis. No pig was operated on urgently to manage an acute complication. The complication rate was 20% due to 2 wound infections. The macroscopic examination of the explanted colon articles found one case of stricture under the prosthesis location (10%). Local smooth adhesions were noted in 7 pigs (70%). No histologic rejection was noted during the anatomopathologic tests for all pigs. CONCLUSION: The use of bovine collagen bilayer prosthesis in digestive surgery may prove to be safe and effective to treat digestive leakage. It may be feasible to use this type of biomaterial to prevent fistula of the digestive tract, including anastomotic. A prospective trial would need to be performed to complete this research to give the surgeons an opportunity to improve treatment in many digestive procedures.

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.

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.

Despite being one of the commonest surgical procedures, few methodologically suitable evaluations of inguinal hernia repair have been conducted in France. Between September 1995 and November 2000 men with inguinal hernias at 7 surgical centers were randomly assigned to open or laparoscopic repair. The primary endpoint was recurrence of hernias at two years and secondary endpoints were complications and postoperative pain (Visual Analogic Score). Of 404 patients assigned to one of the two procedures, 390 were available for the analysis. Median follow-up was 2.8 years for open surgery (Shouldice 98%) and 2.3 years for laparoscopy (TAP 55%; TEP 45%). Two-year follow-up was 66%. Recurrences were more common in the laparoscopic group (15.5%) than in the open group (6%) odds ratio 2.75; 95% confidence interval 1.20-6.85. This difference was statistically significant for direct hernias exclusively. The three severe intraoperative complications were reported in the laparoscopic group. The rate of local complications at 8 and 30 postoperative days were not different between the two techniques, however 8 of 9 patients with testicular pain were in the laparoscopic group. Postoperative pain at one month was less severe in the laparoscopic than in the open group (VAS 1.41.9 and 3.12.6 respectively). The rate of patients with postoperative pain (VAS>2) at one year was not related to the open or laparoscopic technique (overall 8.5%). Mean PREoperative VAS of patients with longterm postoperative pain was higher than PREoperative VAS of patients without postoperative pain, 3.9 and 2.2 respectively. Mean operating room occupation times were 11637 min and 16965 min for open and laparoscopic surgery respectively. Subject to limitations associated with the present study follow-up, open surgery might be superior to laparoscopic surgery for inguinal hernia repair.

BACKGROUND: Nowadays, laparoscopic adrenalectomy is the "gold standard" procedure for the treatment of benign lesions. However, the situation is not so clearcut when the issue is laparoscopic excision of malignant adrenal tumors. We present our results of laparoscopic adrenalectomy for treating malignant tumors over the past decade. METHODS: Between October 1995 and June 2004, 131 consecutive laparoscopic adrenalectomies were performed on 120 patients (11 synchronous bilateral procedures). All patients underwent a standardized investigation protocol during their workup for surgery. RESULTS: There were only two conversions to laparotomy (1.6%). Complications that occurred during the procedure were limited to six patients (5%). Postoperative 30-days mortality was nil. Postoperative complications occurred in five patients (4.7%) during the first 30 days of recovery. The median hospital stay for all patients was 2.5 days (range = 2-10 days). Twelve patients (9%) had a malignant tumor: nine corticoadrenalomas, one pleomorphic sarcoma, one metastatic deposit from a previously excised colonic cancer, and one malignant pheochromocytoma. At mean followup of 34 months, mean survival time was 42.3 months for corticoadrenalomas that had undergone laparoscopy versus 29.7 months for those who had had a laparotomy. Five of the nine patients are alive and well at a mean of 37 months following surgery. One patient developed pulmonary metastases one year postsurgery; they were responsive to mitotane. Five years later, the same patient had a reoperation for an intra-abdominal retrogastric recurrence of her tumor and continues to do well. Another patient developed pulmonary metastases 22 months following adrenalectomy. Two patients died of metastatic intra-abdominal disease 20 and 7 months postsurgery. CONCLUSION: When laparoscopic surgery is to used for cancer treatment, caution is the rule to maintain the primary objective of securing a survival rate at least as high as that for open surgery, without increased risk of recurrence. Considering the results presented within this study, it seems that the laparoscopic removal of a corticoadrenaloma should not worsen the prognosis, provided the surgeon respects the primary rules of oncologic resectional surgery. Any surgical conditions that would preclude the strict application of these criteria are contraindications to a laparoscopic procedure.

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.
