BACKGROUND/OBJECTIVE: Restorative proctocolectomy (RP) may improve quality of life in patients with ulcerative colitis (UC)-associated lower rectal cancer to a greater extent than total proctocolectomy. However, patients with UC-associated cancer often have flat mucosal lesions that make it extremely difficult to endoscopically delineate the tumor margins. Therefore, there is a potential risk of residual tumor and local recurrence after RP in patients with UC-associated lower rectal cancer...

BACKGROUND: Many surgical techniques have been developed to treat inguinal hernia. In recent years, the laparoscopic transabdominal preperitoneal (TAPP) approach has been widely performed to repair inguinal hernia. Giant inguinal hernia (GIH) is an extremely rare disease that is a challenge for general surgeons. GIH appears when patients neglect the treatment for many years and it is defined as an inguinal hernia that extends below the midpoint of inner thigh in standing position. According to previous publications, the Lichtenstein tension-free hernioplasty is recommended to repair GIH...

BACKGROUND: In patients with acute biliary pancreatitis (ABP), cholecystectomy is mandatory to prevent further biliary events, but the precise timing of cholecystectomy for mild to moderate disease remain a subject of ongoing debate. The aim of this study is to assess the outcomes of early versus delayed cholecystectomy. We hypothesize that early cholecystectomy as compared to delayed cholecystectomy reduces recurrent biliary events without a higher peri-operative complication rate. METHODS: Patients with mild to moderate ABP were prospectively randomized to either an early cholecystectomy versus a delayed cholecystectomy group...
