Comparison of warm sitz bath and electronic bidet with a lower-force water flow for postoperative management after hemorrhoidectomy (BIDLOW).

Aim: Electronic bidets can be a substitute for sitz baths, but no study has examined the use of electronic bidets to manage anal problems.

Methods: A randomized, controlled, single-blind, multicenter, parallel group trial was performed. Patients who underwent hemorrhoidectomy were randomly assigned (1:1) to use the electronic bidet or warm sitz baths for 7 days after hemorrhoidectomy.

Clinical Characteristics and Incidence of Perianal Diseases in Patients With Ulcerative Colitis.

Purpose: While perianal disease (PAD) is a characteristic of patients with Crohn disease, it has been overlooked in patients with ulcerative colitis (UC). Thus, our study aimed to analyze the incidence and the clinical features of PAD in patients with UC.

Methods: We reviewed the data on 944 patients with an initial diagnosis of UC from October 2003 to October 2015.

Clinical Features of Tuberculous Versus Crohn's Anal Fistulas, in Korea.

Background And Aims: In Western countries, tuberculous anal fistula may not be an issue because tuberculosis [TB] is not common, and this is a very rare form of extrapulmonary manifestation of TB. However in TB-endemic countries, careful diagnostic differentiation is required because the clinical features of TB anal fistula and Crohn's disease [CD] anal fistula are similar, with distinguishing features remaining unclear. We aimed to analyse the clinical features of TB versus CD anal fistulas.

The influence of reconstruction methods on food retention phenomenon in the remnant stomach after a subtotal gastrectomy.

Background And Objectives: Food retention and bile reflux has been frequently observed in gastric cancer patients following a subtotal gastrectomy. The aim of this study was to determine whether reconstruction methods after the distal subtotal gastrectomy influenced the degree of food residue and bile reflux.

Methods: The prospectively collected data was reviewed retrospectively for 522 patients with early gastric cancer who had undertaken a follow-up endoscopic examination after a distal subtotal gastrectomy between 2003 and 2006.
