RESUMEN
Objective To evaluate complications from two anal stapling operations of anorectal surgery,the procedure for prolapse and hemorrhoids (PPH) and the stapled transanal rectal resection (STARR).Methods The data of 1 276 patients undergoing PPH for hemorrhoids and 149 patients having STARR for ODS from January 2010 to January 2015,in Beijing Chaoyang Hospital were studied.More than six months of follow-up was done.Statistics used included t Test and Chi-square test,Logistic regression analysis.Results Complications of PPH and STARR included hemorrhage in 27 cases (2.1％) vs.3 cases (2.0％);pain in 285 cases (22.3％) vs.6 cases (4.0％);uroschesis in 96 cases (7.5％) vs.12 cases (8.1％);edema in 227 cases (17.8％) vs.16 cases (10.7％);defecatory urgency in 194 cases (15.2％) vs.38 cases (25.5％);anastomotic infection in 17 cases (1.3％) vs.2 cases (1.3％);mild anal incontinence in 11 cases (0.9％) vs.2 cases (1.3％);anastomotic stenosis in 11 cases (0.9％) vs.1 case (0.7％).There was a positive correlation between dry stool,defecatory urgency and hemorrhage after PPH.PPH compared to STARR:The post-operative pain,edema and defecatory urgency and overall complication rate was significantly different (t =26.51,x2 =4.69,x2 =10.38,x2 =37.12,P ＜ 0.05).Conclusions PPH and STARR have rare serious complications and easy to handle.Abnormal defecation such as dry stool and defecatory urgency is an important risk of hemorrhage.
