Oncologic safety of colonic stenting as a bridge to surgery in left-sided malignant colonic obstruction: Current evidence and prospects.

Approximately 7%-29% of patients with colorectal cancer present with colonic obstruction. The concept of self-expandable metal stent (SEMS) insertion as a bridge to surgery (BTS) is appealing. However, concerns on colonic stenting possibly impairing oncologic outcomes have been raised.

Video-Assisted Ligation of Intersphincteric Fistula Tract for Complex Anal Fistula: Technique and Preliminary Outcomes.

Background: Sphincter-preserving operations have been increasingly used for treating anal fistula. However, their success rates remain modest in complex anal fistulas.

Objective: This study aimed to report outcomes of video-assisted ligation of intersphincteric fistula tract (a procedure combining video-assisted anal fistula treatment and ligation of intersphincteric fistula tract) for treating complex anal fistulas and to compare its results with conventional ligation of intersphincteric fistula tract.
