Consensus of Chinese experts on defecation management during perioperative period of benign anal diseases / 中华胃肠外科杂志

The significant increase in the incidence of benign anal diseases is related to the fast-paced life style, the change of dietary structure, the increase of work pressure and social psychological factors. Surgery is one of the most important treatments for benign anal diseases, while perioperative defecation management is closely related to the efficacy of surgery. In current clinical practice, there is no consensus on the management of perioperative defecation for benign anal diseases. Hence a discussion was held by the Professional Committee of Colorectal Diseases of Chinese Society of Integrated Chinese and Western Medicine, concerning the causes of perioperative defecation difficulties in perioperative anal benign diseases, the importance and specific strategy of defecation management. A consensus was consequently formed, aiming to provide a guideline for the clinical practice.

Clinical significance of preoperative colonoscopy for benign anal diseases / 中华消化外科杂志

Objective To investigate the clinical significance of preoperative colonoscopy for patients with benign anal diseases,and to compare the success rates of examination done by sedated colonoscopy and conventional colonoscopy.Methods The clinical data of 333 patients with benign anal disease who received preoperative colonoscopy at the Six Affiliated Hospital of Sun Yat-Sen University from April 2010 to March 2011 were retrospectively analyzed.All the patients were divided into the lesion group (120 patients) and normal group (213 patients)according to the results of colonoscopy.The measurement data and count data were analyzed using the t test and chi-square test,respectively.Results The age of patients in the lesion group was (48 ± 14) years,which was significantly older than (42 ± 14) years (t =3.75,P ＜ 0.05).The constituent ratio of patients older than 40 years in the lesion group was 72.50％ (87/120),which was significantly higher than 39.44％ (84/213) in the normal group (x2=33.59,P ＜0.05).The proportions of male and female patients were 71.67％ (86/120) and 28.33％ (34/120) in the lesion group,and 62.44％ (133/213) and 37.56％ (80/213) in the normal group,with no significant difference between the 2 groups (x2 =2.90,P ＞ 0.05).The benign anal diseases in the lesion group included polyp (80 cases),enteritis (30 cases),malignant tumor (7 cases),infflammatory bowel disease (7 cases),diverticulum (5 cases) and ulcer (1 case).The application rates of sedated colonoscopy in the lesion group and the normal goup were 51.67％ (62/120) and 54.93％ (117/213),respectively,with no significant difference between the 2 groups (x2=0.33,P ＞0.05).The success rate of terminal ileum intubation was 99.44％ (178/179) in patients who received sedated colonoscopy,which was significantly higher than 95.45％ (147/154) of patients who received conventional colonoscopy (x2 =5.61,P ＜ 0.05).Conclusion Patients with benign anal disease might complicated with colorectal lesions,and sedated colonoscopy is recommended for preoperative diagnosis,especially for patients who are older than 40 years.
