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., (© 2020 BJS Society Ltd Published by John Wiley & Sons Ltd.)

Background: Postoperative ileus involves an inflammatory pathway characterized by an increase of inflammation mediators in the colon wall; this could probably be prevented by sacral nerve neuromodulation. The posterior tibial nerve can be stimulated electrically to mimic neuromodulation., Objective: The aims of this study were to assess the efficacy of transcutaneous posterior tibial nerve stimulation in reducing the delay in GI motility recovery, to assess the safety of posterior tibial nerve stimulation in a perioperative setting, and to assess the efficacy of posterior tibial nerve stimulation in reducing the occurrence of postoperative ileus., Design: This was a preliminary randomized controlled study., Settings: This study was conducted in 1 academic hospital in France., Patients: Forty patients undergoing an elective colectomy were included and randomly assigned into 2 groups, posterior tibial nerve stimulation or placebo, according to the side of colectomy and the surgical access size., Intervention: Perioperative posterior tibial nerve stimulation or placebo was performed 3 times per day according to the randomly assigned group., Main Outcome Measures: Delay in GI motility recovery (passage of stool and tolerance of solid food) was measured., Results: Of the 40 patients included, 34 were included in the final analysis, in which 2 patients in the placebo group were allocated the incorrect device. The 6 other patients were secondarily excluded because of protocol deviation. In the intention-to-treat analysis, the mean delay in GI motility recovery was 3.6 and 3.11 days (in the placebo and tibial nerve stimulation groups; p = 0.60). Occurrence of postoperative ileus was not significantly higher in the placebo group (35.3% vs 17.6%; p = 0.42). In the per-protocol analysis, we observed the same trends except for the occurrence of postoperative ileus, which was significantly higher in the placebo group (p = 0.045). Tolerance to posterior tibial nerve stimulation was good, and all of the patients completed the protocol., Limitations: The amplitude of stimulation is set according to patient sensation, so some patients could have been aware of their group. In addition there were some inherent limitations because of the preliminary nature of the study and several deviations from the protocol., Conclusions: Posterior tibial nerve stimulation was safe in a perioperative setting and had a potential effect on GI motility recovery. The results of this study will be useful for sample size calculations in a larger prospective randomized trial. See Video Abstract at http://links.lww.com/DCR/A708.

We report here the case of a young man suffering from a rare germ cell tumour. The patient was a 25-year-old man who was referred to our centre for asthenia, stinging epigastric pain, and an iron deficiency anaemia. Gastroscopy revealed a circumferential vegetating lesion on the second portion of the duodenum. The lesion was indurated at the third portion of the duodenum, responsible for a tight stenosis. A computerized tomography-scan of the chest, abdomen and pelvis, and a pancreatic MRI showed a circumferential lesion with a bi-ductal dilatation ( i.e ., of the common bile duct and Wirsung's duct) without metastatic localisation. The patient underwent a pancreaticoduodenectomy with lymph node dissection including all cellular adipose tissues of the hepatic pedicle from the hepatic common artery and of the retroportal lamina. Histological findings were suggestive of a duodenal embryonal carcinoma with pancreatic infiltration. This is the second published case highlighting the duodenal primitive localisation of an embryonal carcinoma with pancreatic infiltration., Competing Interests: Conflict-of-interest statement: All authors declare no conflict of interest related to this manuscript.

Objective: The aim of this retrospective study was to determine the risk factors of early complications after progressive pneumatic dilation for achalasia., Methods: Five hundred four dilations were performed in 237 consecutive achalasic patients between 1980 and 1994 with the same technique: low-pressure pneumatic dilation every other day with balloons of increasing diameter until success criteria were obtained (depending on manometric examination and esophageal x-ray transit performed 24 h after each dilation). Clinical, radiographical, endoscopical, and manometrical data as technical procedure characteristics for patients with perforations or other early complications were compared with those without complications., Results: We observed 15 complications (6% of patients): 7 perforations (3%), 3 asymptomatic esophageal mucosal tears, 4 esophageal hematomas, and 1 fever. Perforations occurred in 6 of 7 patients during the first dilation. The mean age was 68.5 yr in the group with complications versus 56.4 yr for the remainder (p < 0.05). Two deaths occurred in patients older than 90 yr. Instability of the balloon during dilations was noted in 8 of 15 cases of complications versus 57 of 222 patients (p < 0.05). No other data differed significantly., Conclusions: This study showed a low prevalence of early complications using this progressive technique. Patients with hiatal hernia, esophageal diverticulum, or vigorous achalasia may safely undergo progressive pneumatic dilation. Only patients older than 90 yr should be referred for progressive pneumatic dilation with caution. Most of perforations arose during the first dilation, but there was no predictive pretherapeutic factor of perforation.

Assessment of total and segmental colonic transit times (CTT) in man using a single type of radiopaque marker and one abdominal X-ray has been validated but not extensively studied. The aims of our prospective study were to establish normal values of this method as a function of age, gender and fiber intake in healthy subjects. Eighty-two healthy volunteers (51 men, 31 women, mean age 38 yr, range 21-61) with normal stool frequency (between 3/day and 3/week) and no history of gastrointestinal disease or medication were enrolled and ingested 10 small (3 mm edge) radiopaque markers every morning for 6 consecutive days. On the 7th day, an abdominal X-ray was performed to calculate total and segmental (right, left, rectosigmoid) CTT according to Arhan's method (CCT = 2.4 N; N = number of markers in the considered zone). During the study the number of stools was recorded and fiber intake estimated on a questionnaire. Stool frequency, total and segmental CTT were evaluated for differences due to age, gender and/or fiber intake. In volunteers, total, left and rectosigmoid CTT were closely related to stool frequency (P = 0.0001) being longer in women than in men (P < 0.02). In contrast, right CTT was independent of gender or stool frequency. Finally, in this group CTT were independent of age and fiber intake. This study confirms the influence of gender on CTT and demonstrate the ability of this simple and non-invasive method (0.08 mrad surface exposure) to assess CTT. Its use as a diagnostic tool in self-defined constipated patients would be of interest in clinical practice.

In order to assess the relationship between increase of gamma-glutamyl transferase and diabetes, we measured serum gamma-glutamyl transferase in 48 male and 43 female insulin-dependent diabetics aged 20-60 years, 49 male and 41 female non insulin dependent diabetics aged 30-60 years, and in 114 male and 124 female controls (blood donors) aged 20-60 years. A1C haemoglobin was assayed in 124 diabetics. There is no increase of serum gamma-glutamyl transferase activity in insulin dependent diabetics of both sexes when compared with the controls. There is an increase of serum gamma-glutamyl transferase activity in non insulin dependent diabetics when compared either with controls (men p less than 0.02, women p less than 0.02) or with insulin dependent diabetics (men p less than 0.05, women p less than 0.02). There is no correlation between serum gamma-glutamyl transferase activity and fasting blood sugar (148 diabetics). In non insulin dependent diabetics of both sexes there is no correlation between A1C haemoglobin and serum gamma-glutamyl transferase activity. These results suggest that the increase observed in diabetics is not caused by diabetes itself, ie, by hyperglycemia, but by diabetes associated pathologies.
