Objective: To study the value of ultrasound, abdominal X-ray, and dual-source CT (DSCT) in the diagnosis of colon tumor obstruction.
Methods: A retrospective analysis was conducted among 45 patients who were admitted to our department between October 2010 and August 2011 for abdominal pain. All the patients underwent ultrasound, abdominal X-ray and DSCT examinations and subsequent surgical interventions, which confirmed the diagnosis of colon tumor obstruction.
Results: DSCT diagnosis was obviously more efficient than ultrasound and X-ray in detecting colon obstruction by neoplasms, and could better predict the position of the obstruction. Complete information of the vessels in the surgical field could be obtained by DSCT imaging three-dimensional reconstruction.
Conclusions: Compared with ultrasound and X-ray, DSCT is more effective in the diagnosis of colon tumor obstruction by acquiring more thorough information by imaging reconstruction and should be considered for a rapid and accurate diagnosis.

Introduction: Primary sclerosing cholangitis (PSC) is the classical hepatobiliary manifestation of inflammatory bowel disease (IBD). The strong association between gut and liver inflammation has driven several pathogenic hypotheses to which the intestinal microbiome is proposed to contribute. Pilot studies of faecal microbiota transplantation (FMT) in PSC and IBD are demonstrated to be safe and associated with increased gut bacterial diversity.

Objective: Artificial intelligence (AI) tools for histological diagnosis offer great potential to healthcare, yet failure to understand their clinical context is delaying adoption. IGUANA (Interpretable Gland-Graphs using a Neural Aggregator) is an AI algorithm that can effectively classify colonic biopsies into normal versus abnormal categories, designed to automatically report normal cases. We performed a retrospective pathological and clinical review of the errors made by IGUANA.

Objectives: Patients with Peutz-Jeghers syndrome (PJS) require continuous medical management throughout their lives. However, few case series regarding the clinical course, polyp surveillance, and treatment, including endoscopic ischemic polypectomy (EIP) for pediatric patients with PJS, were reported. We analyzed the current status and clinical course of pediatric patients with PJS under the management of our institute, including those treated with EIP.

Aim: Complete mesocolic excision (CME) is an oncologically driven technique for treating right colon cancer. While laparoscopic CME is technically demanding and has been associated with more complications, the robotic approach might reduce morbidity. The aim of this study was to assess the safety of stepwise implementation of robotic CME.
