Laparoscopic cholecystectomy complications: a new case report of a right hepatic artery pseudoaneurysm that caused jaundice.

Iatrogenic vascular injuries of the hepatic artery are infrequent and a serious complication of LC. There is no doubt about the many advantages of LC when compared to open cholecystectomy. Despite this, there is an increase in the reported incidence (0.3%-1.0%) of biliary and vascular injuries. Most arterial complications are due to direct injury or diathermy shortening on surgical clips and HAP is one of them. We present a case of a 39-year old male patient who presented with this complication and how it was resolved.

Insertion of fully covered self-expanding metal stents in benign biliary diseases.

INTRODUCTION: Benign biliary diseases are traditionally treated using plastic stents. However, fully covered self-expanding metal stents are currently gaining acceptance for the treatment of these pathologies. OBJECTIVE: To assess the effectiveness and complications associated with the placement of temporary endoscopic fully covered self-expanding metal stents for the treatment of benign biliary diseases. MATERIALS AND METHODS: This was a retrospective and observational study using a prospective database from a tertiary care center from March 2012 to May 2016. Some patients that had a fully covered metal stent due to a benign biliary disease were also included. The indications, resolution, technical success rates and adverse events were documented. RESULTS: 31 patients were included with a total of 34 stents inserted. The indications were as follows: 8 (25%) post cholecystectomy biliary stenoses, 11 (31%) large or multiple choledocholithiasis, 3 (8.3%) biliary fistulas, 2 (6%) post-liver transplant stenoses, 2 (8.3%) papillary stenoses, 2 (6%) perforations and 2 (6%) bleeds. The global resolution success rate of the stents for all pathologies was 88%, this included 87.5% (7/8) in post cholecystectomy stenoses, 73% (8/11) in large choledocholithiasis and 100% for the remaining indications. Thirty-three of 34 stents were removed after an average of 133 days (ranging from 10 to 180 days). No complications were registered. CONCLUSION: Fully covered self-expanding metal stents are an effective and reliable alternative for the resolution of benign biliary diseases.

Risk of colorectal neoplasia in patients with celiac disease: a multicenter study.

BACKGROUND AND AIMS: The association of celiac disease with colorectal neoplasia is controversial. The aim of this study was to determine the risk of colorectal neoplasia among patients with celiac disease. METHODS: We carried out a multicenter, retrospective case-control study, within four community hospitals. Celiac disease patients with a complete colonoscopy were regarded as cases and those without celiac disease as controls. For each case, two controls matched for age, sex, indication for colonoscopy and colorectal cancer family history, were randomly selected. The main outcome evaluated was risk of colorectal polyps, adenomas, advanced neoplastic lesions and cancer. RESULTS: We identified 118 patients with celiac disease and 236 controls. The risk of polyps, adenomas and advanced neoplastic lesions was similar in both groups (OR 1.25, CI 0.71-2.18, p=0.40; OR 1.39, CI 0.73-2.63, p=0.31; and OR 1.00, CI 0.26-3.72, p=1.00, respectively). On multivariate analysis, age >75 years old, and first-grade CRC family history were associated with adenomas (OR 2.68 CI 1.03-6.98, OR 6.68 CI 1.03-47.98 respectively) and advanced neoplastic lesions (OR 15.03, CI 2.88-78.3; OR 6.46 CI 1.23-33.79, respectively). With respect to celiac disease characteristic, a low adherence to a gluten free diet was independently associated with the presence of adenomas (OR 6.78 CI 1.39-33.20 p=0.01). CONCLUSIONS: Celiac disease was not associated with an increased risk of colorectal neoplasia. Nonadherence to a strict gluten free diet was associated with the presence of adenomas. Further studies addressing celiac disease characteristics are needed to confirm this observation.
