Comparison of three Methods of Preparation for Anorectal Surgeries (Hemorrhoid and Fistula): Mechanical Bowel Prep with Polyethylenglycol, Saline Enema, and no Preparation

Introduction & Bowel mechanical preparation is a routine procedure before colorectal surgeries. Anorectal procedures are most prevalent procedures in general surgery. To reduce risk of infection and better performance, all authors insist on bowel preparation before anorectal surgeries. The aim of this study is the comparison of the mechanical bowel preparation with polyethylenglycol (PEG), saline enema or no prep before anorectal surgery (hemorrhoid and fistula). In a randomized clinical trial 150 cases of candidates for elective hemorrhoid or fistula in general surgery ward of hospital enrolled came under study: 50cases in PEG group (1), 50 cases in saline enema (2) and 50 cases with no prep or control (3). After surgery surgeon's satisfaction, pain after first defecation and post operative complications were evaluated and analyzed by SPSS 16, ANOVA and chi-square test. The mean of age, gender and procedure type were not different significantly between groups. Surgeon's satisfaction was 26% in group 1, 28% in group 2 and 0% in group 3; difference was significant (P-value.
