RESUMEN
OBJECTIVES: Postoperative infections occur frequently after pancreaticoduodenectomy, especially in patients with bile colonization. Recommendations for perioperative anti-infectious treatment are lacking, and clinical practice is heterogenous. We have analyzed the effects of bile colonization and antibiotic prophylaxis on postoperative infection rates, types and therapeutic consequences. METHODS: Retrospective observational study in patients undergoing pancreaticoduodenectomy with intraoperative bile culture. Data on postoperative infections and non-infectious complications, bile cultures and antibiotic prophylaxis adequacy to biliary bacteria were collected. RESULTS: Among 129 patients, 53% had a positive bile culture and 23% had received appropriate antibiotic prophylaxis. Postoperative documented infection rate was over 40% in patients with or without bile colonization, but antibiotic therapy was more frequent in positive bile culture patients (77% vs. 57%, P=0,008). The median duration of antibiotic therapy was 11 days and included a broad-spectrum molecule in 42% of cases. Two-thirds of documented postoperative infections involved one or more bacteria isolated in bile cultures, which was associated with a higher complication rate. While bile culture yielded Gram-negative bacilli (57%) and Gram-positive cocci (43%), fungal microorganisms were scarce. Adequate preoperative antibiotic prophylaxis according to bile culture was not associated with reduced infectious or non-infectious complication rates. CONCLUSION: Patients undergoing pancreaticoduodenectomy experience a high rate of postoperative infections, often involving bacteria from perioperative bile culture when positive, with no preventive effect of an adequate preoperative antibiotic prophylaxis. Increased postoperative complications in patients with bile colonization may render necessary a perioperative antibiotic treatment targeting bile microorganisms. Further prospective studies are needed to improve the anti-infectious strategy in these patients.

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.

STUDY OBJECTIVE: It has been demonstrated that mortality following pancreatectomy is correlated with surgical volume. However, up until now, no French study has focused on predictive factors to undergo pancreatectomy in low-volume centers. The objective of this study is to analyze the clinical characteristics, socio-economic status and medical density according to surgical volume and to analyze predictive factors for undergoing pancreatectomy in low-volume centers. PATIENTS AND METHODS: All patients who underwent pancreatectomy in France from 2012 to 2015 were identified fromthe PMSI database. Hopsitals were classified as low, intermediate and high volume (<10, 11-19, ≥20 resections/year, respectively). Clinical and socioeconomic data, travel distance and rurality were assesed to identify factors associated with undergoing pancreatectomy at low-volume hospitals. RESULTS: In overall, 12,333 patients were included. Those who underwent pancreatectomy in low-volume centers were more likely older, had high Charlson comorbidity index (CCI), had low socioeconomic status, and resided in rural locations.distance traveled by patients operated on in low-volume centers was significantly shorter (23 vs. 61km, P<0.001). In multivariable analysis, older age (P=0.04), CCI≥4 (P=0.008), short travel distance (P<0.001), low socio-economic status (P<0.001) and rurality (P<0.001) were associated withundergoing pancreatectomy in low-volume centers. CONCLUSION: Patients continue to undergo pancreatectomy at low-volume hospitals is due not only to clinical parameters, but also to socioeconomic and environmental factors. These factors should be taken into account in process of pancreatic surgery centralization.

Neoplastic gallbladder polyps (NGP) are rare; the prevalence in the overall population is less than 10%. NGP are associated with a risk of malignant degeneration and must be distinguished from other benign gallbladder polypoid lesions that occur more frequently. NGP are adenomas and the main risk associated with their management is to fail to detect their progression to gallbladder cancer, which is associated with a particular poor prognosis. The conclusions of the recent European recommendations have a low level of evidence, based essentially on retrospective small-volume studies. Abdominal sonography is the first line study for diagnosis and follow-up for NGP. To prevent the onset of gallbladder cancer, or treat malignant degeneration in its early phases, all NGP larger than 10mm, or symptomatic, or larger than 6mm with associated risk factors for cancer (age over 50, sessile polyp, Indian ethnicity, or patient with primary sclerosing cholangitis) are indications for cholecystectomy. Apart from these situations, simple sonographic surveillance is recommended for at least five years; if the NGP increases in size by more than 2mm in size, cholecystectomy is indicated. Laparoscopic cholecystectomy is possible but if the surgeon feels that the risk of intra-operative gallbladder perforation is high, conversion to laparotomy should be preferred to avoid potential intra-abdominal tumoral dissemination. When malignant NGP is suspected (size greater than 15mm, signs of locoregional extension on imaging), a comprehensive imaging workup should be performed to search for liver extension: in this setting, radical surgery should be considered.

BACKGROUND: To determine whether the timing of removal of abdominal drainage (AD) after pancreatoduodenectomy (PD) influences the 30-day surgical site infection (30-day SSI) rate. METHODS: A multicenter randomized, intention-to-treat trial with two parallel arms (superiority of early vs. standard AD removal on SSI) was performed between 2011 and 2015 in patients with no pancreatic fistula (PF) on POD3 after PD (NCT01368094). The primary endpoint was the 30-day SSI rate. The secondary endpoints were specific post-PD complications (grade BC PF), postoperative morbidity and risk factor of SSI, reoperation rate, 30-day mortality, length of drainage, length of stay and postoperative infectious complications. RESULTS: One hundred and forty-one patients were randomized: 71 in the early arm, 70 in the standard arm (70.2% of pancreatic adenocarcinomas; 91.5% of pancreatojejunostomies; 66.0% of bilateral drainages; feasibility: 39.9%). Early removal of drains was not associated with a significant decrease of 30-day SSI (14.1% vs. 24.3%, P=0.12). A lower rate of deep SSI was observed in the early arm (2.8% vs. 17.1%, P=0.03), leading to a shorter length of stay (17.8±6.8 vs. 21.0±6.1, P=0.01). Grade BC PF rate (5.6%), severe morbidity (17.7%), reoperation rate (7.8%), 30-day mortality (1.4%) and wound-SSI rate (7.8%) were similar between arms. After multivariate analysis, the timing of AD removal was not associated with an increase of 30-day SSI (OR=0.74 [95% CI 0.35-1.13, P=0.38]). CONCLUSION: In selected patients with no PF on POD3, early removal of abdominal drainage does not seem to increase or decrease surgical site infection's occurrence.

OBJECTIVE: To define the cost of pancreatectomies and to identify factors associated with increased hospital costs after pancreatic resection. METHODS: All patients undergoing pancreatic surgery in our department between January 2008 and December 2014 were included. All complications occurring during hospitalization or in the 90-day period after discharge were documented. The hospital costs were analyzed and predictive factors of increased hospital costs were determined. RESULTS: One hundred and twenty seven patients were identified. Most patients underwent pancreatectomy for malignant tumors (70%). Median hospital costs were 21,392 [15,998-29,667] euros. Age (P=0.011) and preoperative jaundice (P<0.001) were associated with higher hospital costs. Intraoperative surgical time and blood loss were correlated with increased costs (P=0.001 and P=0.002, respectively). Pancreatoduodenectomy was associated with statistically significantly higher costs compared to distal pancreatectomy (21,770 vs. 15,422 euros, P=0.001). Severe postoperative complications (Clavien-Dindo grade≥3) (P=0.001), septic complications (P=0.002) and hemorrhage (P=0.001) statistically significantly increased costs. In multivariate analysis, septic (P=0.003) and severe complications (P=0.01) were statistically significantly associated with increased hospital costs. CONCLUSION: Pancreatic surgery is associated with high hospital costs, essentially related to postoperative complications.

BACKGROUND: Biliary leakage remains a major cause of morbidity after liver resection. Previous prognostic studies of posthepatectomy biliary leakage (PHBL) lacked power, population homogeneity, and model validation. The present study aimed to develop a risk score for predicting severe PHBL. METHODS: In this multicentre observational study, patients who underwent liver resection without hepaticojejunostomy in one of nine tertiary centres between 2012 and 2015 were randomly assigned to a development or validation cohort in a 2 : 1 ratio. A model predicting severe PHBL (International Study Group of Liver Surgery grade B/C) was developed and further validated. RESULTS: A total of 2218 procedures were included. PHBL of any severity and severe PHBL occurred in 141 (6·4 per cent) and 92 (4·1 per cent) patients respectively. In the development cohort (1475 patients), multivariable analysis identified blood loss of at least 500 ml, liver remnant ischaemia time 45 min or more, anatomical resection including segment VIII, transection along the right aspect of the left intersectional plane, and associating liver partition and portal vein ligation for staged hepatectomy as predictors of severe PHBL. A risk score (ranging from 0 to 5) was built using the development cohort (area under the receiver operating characteristic curve (AUROC) 0·79, 95 per cent c.i. 0·74 to 0·85) and tested successfully in the validation cohort (AUROC 0·70, 0·60 to 0·80). A score of at least 3 predicted an increase in severe PHBL (19·4 versus 2·6 per cent in the development cohort, P < 0·001; 15 versus 3·1 per cent in the validation cohort, P < 0·001). CONCLUSION: The present risk score reliably predicts severe PHBL. It represents a multi-institutionally validated prognostic tool that can be used to identify a subset of patients at high risk of severe PHBL after elective hepatectomy.

PURPOSE: Best clinical management of severe caustic injury is still a subject of debate. Most surgical teams consider severe caustic injury as an indication for emergency surgery. But, under certain circumstances, conservative management is feasible, avoids the need for gastrectomy, and has a low mortality rate. Postponed reconstructive surgery is usually performed several months after caustic ingestion to restore intestinal continuity or to treat stricture sequelae. This study aimed to investigate long-term nutritional and quality of life (QoL) outcomes after reconstructive surgery for high-grade esophageal and gastric caustic injury. METHODS: Twenty-one patients were assessed for biological and nutritional parameters, physical findings, and quality of life surveys at least 25 months after reconstructive surgery among patients who have required emergency surgery (n = 10) and patients who did not undergo emergency surgery (n = 11). RESULTS: After median follow-up of 74 months (after caustic ingestion) and 67 months (after reconstructive surgery), patients who avoided emergency surgery experienced faster oral diet resumption (49 vs. 157 days, p = 0.004), less weight loss (0.3 vs. 20 kg, p = 0.002), greater body fat percentage (22 vs. 18 %, p = 0.046), better nutritional and physical status (SF12 PCS 51 vs. 43, p = 0.036), and less trouble eating (EORTC QLQ-OG 25 31 vs. 56, p = 0.01). CONCLUSIONS: Our study is the first to evaluate long-term nutritional and QoL outcomes, following severe caustic injury. It demonstrates better long-term nutritional outcomes and QoL in patients suitable for initial conservative management. These results support full functional recuperation of spared organs, even severely burned. In the absence of clinical or biological signs necessitating immediate surgery, conservative management should be advocated.

Laparoscopic distal pancreatectomy is currently a commonly performed procedure. Twenty-five retrospective studies comparing laparotomy and laparoscopy have dealt with the feasibility of this approach for localized benign and malignant tumors. However, these studies report several different techniques. The aim of this review was to determine if a standardized procedure could be proposed. Based on the literature and the experience of surgeons in the French Association of Hepatobiliary Surgery and Liver Transplantation (ACBHT-Association française de chirurgie hépato-biliaire et de transplantation hépatique), we recommend primary control of the splenic artery, use of linear staplers for pancreatic transection, splenic vein control either at its end or its origin, and, depending on local conditions, preservation of the splenic vessels when splenic preservation is envisioned. Current data do not allow establishment of any definitive recommendations as to the ideal site of pancreatic transection, operative patient position, or the direction of dissection, which mainly depends on local practices. Control of the splenic vein remains the critical point of this procedure, and impacts the intra-operative strategy.

Laparoscopic liver resection has been recognized as a safe and efficient approach since the Louisville Conference in 2008, but its use still remains confined to experienced teams in specialized centers, and may lack some standardization. The 2013 Session of French Association for Hepatobiliary and Pancreatic Surgery (ACHBT) specifically focused on laparoscopic liver surgery and the particular aspects and issues arising since the 2008 conference. Our objective is to provide an update and summarize the current French position on laparoscopic liver surgery. An overview of the current practice of laparoscopic liver resections in France since 2008 is presented. The issues surrounding standardization for left lateral sectionectomy and right hepatectomy, hybrid and hand-assisted techniques are raised and discussed. Finally, future technologies and technical perspectives are outlined.

BACKGROUND: Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) was recently developed to induce rapid hypertrophy and reduce post-hepatectomy liver failure in patients with insufficient remnant liver volume (RLV). However, mortality rates >12% have been reported. This study aimed to analyze the perioperative course of ALPPS and to identify factors associated with morbi-mortality. METHODS: Between April 2011 and September 2013, 62 patients operated in 9 Franco-Belgian hepatobiliary centres underwent ALPPS for colorectal metastases (N = 50) or primary tumors, following chemotherapy (N = 50) and/or portal vein embolization (PVE; N = 9). RESULTS: Most patients had right (N = 31) or right extended hepatectomy (N = 25) (median RLV/body weight ratio of 0.54% [0.21-0.77%]). RLV increased by 48.6% [-15.3 to 192%] 7.8 ± 4.5 days after stage1, but the hypertrophy decelerated beyond 7 days. Stage2 was cancelled in 3 patients (4.8%) for insufficient hypertrophy, portal vein thrombosis or death and delayed to ≥9 days in 32 (54.2%). Overall, 25 patients (40.3%) had major complication(s) and 8 (12.9%) died. Fourteen patients (22.6%) had post-stage1 complication of whom 5 (35.7%) died after stage2. Factors associated with major morbi-mortality were obesity, post-stage1 biliary fistula or ascites, and infected and/or bilious peritoneal fluid at stage2. The latter was the only predictor of Clavien ≥3 by multivariate analysis (OR: 4.9; 95% CI: 1.227-19.97; p = 0.025). PVE did not impact the morbi-mortality rates but prevented major cytolysis that was associated with poor outcome. CONCLUSIONS: The inter-stages course was crucial in determining ALPPS outcome. The factors of high morbi-mortality rates associated with ALPPS are linked to the technique complexity.

PURPOSE: Management of infected abdominal wall defects is a subject of debate, and the use of prosthetic mesh repair is not recommended due to the dramatic rate of mesh infection. The aim of this prospective study was to determine the recurrence rate and long-term outcomes of repairing infected abdominal wall defects using the Strattice porcine acellular dermal matrix reinforcement through a single-stage surgical approach. METHODS: From August 2010 to May 2012, consecutive patients treated for infected abdominal wall defects using Strattice, a biologic prosthesis, were enrolled. All data were collected prospectively and all patients were followed for physical examination and CT scan evaluation. The primary outcome measure was the recurrence rate. RESULTS: Eighteen patients were enrolled and 14 were evaluable. Of these, eight patients had mesh infections and six had enterocutaneous fistulas. Median follow-up was 13 months (range, 3-22) and median length of hospitalization was 13 days (range, 4-56). The Strattice was placed in the intraperitoneal underlay position in 12 patients, and in the retro-rectus position for two. Post-operative complications included skin dehiscence (n = 3), wound infection (n = 2), skin necrosis (n = 1), and seroma (n = 2). At the end of follow-up, six patients (43 %) experienced abdominal wall defect recurrence. CONCLUSIONS: The utility of biologic prostheses to repair infected abdominal wall defects is controversial; however, currently, they remain the only alternative to a two-staged surgery. Prospective, randomized studies in larger populations of patients are necessary to fully determine the usefulness of biologic prostheses in this setting.

BACKGROUND: Perioperative FOLFOX4 (oxaliplatin plus 5-fluorouracil/leucovorin) chemotherapy is the current standard in patients with resectable metastases from colorectal cancer (CRC). We aimed to determine whether a sequential chemotherapy with dose-dense oxaliplatin (FOLFOX7) and irinotecan (FOLFIRI; irinotecan plus 5-fluorouracil/leucovorin) is superior to FOLFOX4. The chemotherapy timing was not imposed, and was perioperative or postoperative. PATIENTS AND METHODS: In this open-label, phase III trial, patients with resectable or resected metastases were randomly assigned either to 12 cycles of FOLFOX4 (oxaliplatin 85 mg/m(2)) or 6 cycles of FOLFOX7 (oxaliplatin 130 mg/m(2)) followed by 6 cycles of FOLFIRI (irinotecan 180 mg/m(2)). Randomization was done centrally, with stratification by chemotherapy timing, type of local treatment (surgery versus radiofrequency ablation with/without surgery), and Fong's prognostic score. The primary end point was 2-year disease-free survival (DFS). RESULTS: A total of 284 patients were randomized, 142 in each treatment group. Chemotherapy was perioperative in 168 (59.2%) patients and postoperative in 116 (40.8%) patients. Perioperative chemotherapy was preferentially proposed for synchronous metastases, whereas postoperative chemotherapy was more frequently used for metachronous metastases. Two-year DFS was 48.5% in the FOLFOX4 group and 50.0% in the FOLFOX7-FOLFIRI group. In the multivariable analysis, more than one metastasis [hazard ratio (HR) = 2.15] and synchronous metastases (HR = 1.63) were independent prognostic factors for shorter DFS. Five-year overall survival (OS) rate was 69.5% with FOLFOX4 versus 66.6% with FOLFOX7-FOLFIRI. CONCLUSIONS: FOLFOX7-FOLFIRI is not superior to FOLFOX4 in patients with resectable metastatic CRC. Five-year OS rates observed in both groups are the highest ever reported in this setting, possibly reflecting the pragmatic approach to chemotherapy timing. CLINICAL TRIALS NUMBER: NCT00268398.

OBJECTIVES: In France, organ donation refusal rates approach 32% of eligible brain deaths. Outright family refusal represents the primary barrier reason for declining organ donation. This retrospective study evaluated factors influencing this decision. MATERIAL AND METHODS: A retrospective chart review at Lille Hospital, France, was conducted on brain-death patients eligible for organ donation between 2010 and 2011. Data were collected regarding patient characteristics, death conditions and reasons for refusal based upon family interview. Descriptive statistic analyses were conducted to identify circumstances associated with family refusal. RESULTS: Of 227 eligible organ donors identified, 70 families (30.8%) refused organ donation. The most frequent reason for refusal was desire to keep the body's wholeness (46.3%), followed by religion (16.4%), mistrust of the medical community (13.4%), and revolt against society (6%). The most common causes of death associated with refusal were brutality and suddenness of death (44.8%), early age (23.9%), denial of death (17.9%), and the family culpability (11.9%). In 30% of cases, the family followed the deceased's wishes before his death. CONCLUSION: Family refusal remains a significant factor associated with the approximately one third of declined eligible organ donations. This retrospective analysis suggested that the most important cause for refusal was a desire to keep the body's wholeness, and the brutality and suddenness of the potential donor's death. Additional research addressing these factors, and their underlying causes, paired with measures to improve professional training and public awareness are warranted to improve organ donation rates.

Our aim was to determine preoperative aerobic capacity (oxygen uptake [V'O2 ]) and prevalence of exercise oscillatory ventilation (EOV), underlying clinical characteristics of patients with EOV, and significance of reduced aerobic capacity and EOV in predicting mortality after liver transplantation. We prospectively studied 263 patients who underwent elective liver transplantation. Patients were followed up for 1 year. Despite minor impairment of resting cardiopulmonary function, preoperative aerobic capacity was reduced (peak V'O2 : 64 ± 19% predicted). EOV occurred in 10% of patients. Model for End-Stage Liver Disease score tended to be higher in patients with EOV compared to patients without, but failed to reach significance (p = 0.09). EOV patients had lower peak V'O2 and higher ventilatory drive. EOV was more frequent in nonsurvivors than in survivors (30% vs. 9%, p = 0.01) and was independently associated with posttransplant all-cause 1-year mortality. Reduced peak V'O2 best predicted the primary composite endpoint defined as 1-year mortality and/or prolonged hospitalization and early in-hospital mortality. Multivariate analysis revealed EOV (χ(2), 3.96; p = 0.04) and V'O2 (χ(2), 4.28; p = 0.04) as independent predictors of mortality and so-called primary composite endpoint, respectively. EOV and reduced peak V'O2 may identify high-risk candidates for liver transplantation, which would motivate a more aggressive treatment when detected.

Hepatic artery (HA) rupture after liver transplantation is a rare complication with high mortality. This study aimed to review the different managements of HA rupture and their results. From 1997 to 2007, data from six transplant centers were reviewed. Of 2649 recipients, 17 (0.64%) presented with HA rupture 29 days (2-92) after transplantation. Initial management was HA ligation in 10 patients, reanastomosis in three, aorto-hepatic grafting in two and percutaneous arterial embolization in one. One patient died before any treatment could be initiated. Concomitant biliary leak was present in seven patients and could be subsequently treated by percutaneous and/or endoscopic approaches in four patients. Early mortality was not observed in patients with HA ligation and occurred in 83% of patients receiving any other treatment. After a median follow-up of 70 months, 10 patients died (4 after retransplantation), and 7 patients were alive without retransplantation (including 6 with HA ligation). HA ligation was associated with better 3-year survival (80% vs. 14%; p=0.002). Despite its potential consequences on the biliary tract, HA ligation should be considered as a reasonable option in the initial management for HA rupture after liver transplantation. Unexpectedly, retransplantation was not always necessary after HA ligation in this series.
