Comparison of application value between conventional air insufflation and water infusion in colonoscopy.

Objective: To discuss the feasibility of water infusion colonoscopy and its difference with traditional air insufflation colonoscopy in application value.

Methods: A prospective randomized controlled clinical study was designed to include 200 patients who underwent sedation-free diagnostic colonoscopy. Among them, 100 patients were treated with water infusion colonoscopy (observation group) and 100 patients were treated with air insufflation colonoscopy (control group).

Clinical Effect of Tunnel-Like Fistulectomy Plus Draining Seton Combined with Incision of Internal Opening of Anal Fistula (TFSIA) in the Treatment of High Trans-Sphincteric Anal Fistula.

BACKGROUND The aim of this study was to investigate the clinical effect of tunnel-like fistulectomy plus draining seton combined with incision of internal opening of anal fistula (TFSIA) in the treatment of high transsphincteric anal fistula. MATERIAL AND METHODS There were 80 patients with high transsphincteric anal fistula randomly divided into TFSIA group and control group, 40 cases in each group. The control group was treated with cutting seton, and the seton was tightened weekly after discharge from the hospital until the seton dropped off.
