Cranial-first approach for laparoscopic extended right hemicolectomy.

Complete mesocolic excision and central vascular ligation with D3 lymphadenectomy are important surgical principles for improving oncological outcomes in colon cancer. The cranial-first approach is a colonic mobilization-first approach to radical right hemicolectomy, which has several advantages, including early feasibility assessment, safe dissection from surrounding organs, preestablished inferior margin of lymph node dissection, and revelation of the tangible anatomy of the tributaries of the gastrocolic trunk. This video demonstrates the cranial-first approach to radical right hemicolectomy in a 66-year-old man with locally advanced cecal cancer.

The weekday effect on postoperative mortality in elective abdominal surgery: An observational study using propensity score methods.

Background: Although the "weekday effect" may influence postoperative outcomes, controversies regarding its existence remain. The aim of this study was to investigate the association between the day of the week the surgery was performed and postoperative outcomes.

Methods: Data from 58,646 patients who underwent elective abdominal surgery at Seoul National University Bundang Hospital from May 2003 to February 2018 were retrospectively analyzed.

Internal hernia after gastrectomy for gastric cancer in minimally invasive surgery era.

Background: The incidence and clinical presentation of internal hernia after gastrectomy have been changing in the minimally invasive surgery era. This study aimed to analyze the clinical features and risk factors for internal hernia after gastrectomy for gastric cancer.

Methods: We retrospectively analyzed internal hernia after gastrectomy for gastric cancer in 6474 patients between January 2003 and December 2016 at Seoul National University Bundang Hospital.
