Parastomal Hernia Following Abdominoperineal Resection

Abstract

Parastomal Hernia (PSH) is a common complication of patient who undergone ostomy especially end colostomy. Presence of hernia defect is associated with the risk of strangulation and obstruction so understanding the potential risk factor such as patient’s factor and technical issues is important. This study is evaluating the incidence of PSH hernia in patients who undergone end colostomy due to Abdominoperineal Resection (APR) in a tertiary colorectal surgery referral center and explore the possible risk factors of this complication.The study was designed as a retrospective cross sectional study on 41 patients who undergone end colostomy due to APR. Three patient lost the follow up and 13 patients died and 25 patients were enrolled in study. Demographic data, history of smoking, steroid administration, Diabetes, obstructive pulmonary disease, transfusion, Neoadjuvant therapy, wound infection and Body mass Index (BMI) were gathered.The mean age of participants was 58.8 and the mean BMI was 25.04 kg/m2. The incidence of PSH was 40% and 68% of operations were done with Laparoscopy. This study could not find statistically significant risk factor for PSH.The 40% incidence of PSH is noticeable and specific strategies should be applied to reduce such complications. Larger studies is essential to investigate the possible etiologies of this complication.
