Introduction To reduce the occurrence of complications in the setting of high-risk patients with contaminated operative field, a wide range of biologic meshes has been developed. Yet, few series have reported outcomes after abdominal wall repair (AWR) using such meshes. Permacol is an acellular porcine dermal collagen matrix with a cross-linked pattern. This study reports short-and long-term outcomes after AWR for incisional hernia using Permacol. Materials and methods All consecutive patients undergoing single-stage open AWR using Permacol mesh at eight university hospitals were included. Mortality, complication and hernia recurrence rates were assessed. Independent risk factors for complications and hernia recurrence were identified with logistic regression and Fine and Gray analysis, respectively. Results Overall, 250 patients underwent single-stage AWR with Permacol. Nearly 80% had a VHWG grade 3 or 4 defect. In-hospital mortality and complication rates were 4.8% (n = 12) and 61.6% (n = 154), respectively. Reintervention for complications was required for 74 patients (29.6%). Mesh explantation rate was 4% (n = 10). Independent risk factors for complications were smoking, defect size and VHWG grade. After a mean follow-up time of 16.8 months (± 18.1 months), 63 (25.2%) experienced hernia recurrence. One-, 2-and 3-year RFS were 90%, 74% and 57%, respectively. Previous AWR, mesh location and the need for reintervention were independent predictors of hernia recurrence. Discussion Single-stage AWR is feasible using Permacol. Mortality and complication rates are high due to patients' comorbidities and the degree of contamination of the operative field. Given the observed recurrence rate, the benefit of biologics remains to be ascertained.This study was presented in part as an oral at the 119th meeting of the French Surgical Association (AFC) held in Paris on September 27, 2017.
Background The aim was to analyse the impact of cirrhosis on short-term outcomes after laparoscopic liver resection (LLR) in a multicentre national cohort study. Methods This retrospective study included all patients undergoing LLR in 27 centres between 2000 and 2017. Cirrhosis was defined as F4 fibrosis on pathological examination. Short-term outcomes of patients with and without liver cirrhosis were compared after propensity score matching by centre volume, demographic and tumour characteristics, and extent of resection. Results Among 3150 patients included, LLR was performed in 774 patients with (24·6 per cent) and 2376 (75·4 per cent) without cirrhosis. Severe complication and mortality rates in patients with cirrhosis were 10·6 and 2·6 per cent respectively. Posthepatectomy liver failure (PHLF) developed in 3·6 per cent of patients with cirrhosis and was the major cause of death (11 of 20 patients). After matching, patients with cirrhosis tended to have higher rates of severe complications (odds ratio (OR) 1·74, 95 per cent c.i. 0·92 to 3·41; P = 0·096) and PHLF (OR 7·13, 0·91 to 323·10; P = 0·068) than those without cirrhosis. They also had a higher risk of death (OR 5·13, 1·08 to 48·61; P = 0·039). Rates of cardiorespiratory complications (P = 0·338), bile leakage (P = 0·286) and reoperation (P = 0·352) were similar in the two groups. Patients with cirrhosis had a longer hospital stay than those without (11 versus 8 days; P = 0·018). Centre expertise was an independent protective factor against PHLF in patients with cirrhosis (OR 0·33, 0·14 to 0·76; P = 0·010). Conclusion Underlying cirrhosis remains an independent risk factor for impaired outcomes in patients undergoing LLR, even in expert centres.
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.
