title: Risk factors of poor functional results at 1-year after pseudocontinent perineal colostomy for ultralow rectal adenocarcinoma.
abstract: BACKGROUND
  Pseudocontinent perineal colostomy is one of the techniques that helps recover the body image of patients undergoing abdominoperineal resection. This technique is rarely used internationally given its unknown functional results.
  
  
  OBJECTIVE
  The study aimed to evaluate 1-year functional outcomes of perineal pseudocontinent colostomy and to determine the risk factors for "poor" functional results.
  
  
  METHODS
  This study is a retrospective interventional case series.
  
  
  METHODS
  This study was conducted at a tertiary care university hospital and oncological center in Morocco.
  
  
  METHODS
  From January 1993 to December 2007, 149 patients underwent pseudocontinent perineal colostomy after abdominoperineal resection for low rectal adenocarcinoma.
  
  
  METHODS
  Pseudocontinent perineal colostomy was performed with the use of the Schmidt technique after abdominoperineal resection.
  
  
  METHODS
  One-year functional results were assessed according to the Kirwan classification system. Functional results were considered "poor" when the Kirwan score was C, D, or E. Univariable and multivariable analyses were used to evaluate the impact of age, sex, type of surgery, irrigation frequency, palpable muscular ring, concomitant chemoradiotherapy, stage, and perineal complications on functional results.
  
  
  RESULTS
  One hundred forty-six patients were analyzed. According to the Kirwan system, the scores showed that 100 (68.5%) patients had "good" continence results (stage A-B) and 46 (31.5%) patients had altered functional results (stage C-D-E). With the exception of pelvic recurrences, no conversions from a perineal colostomy to an abdominal colostomy were performed for dissatisfactory functional results. In multivariate analysis, the only independent predictive factors of poor functional results were the occurrence of perineal complications (OR, 3.923; 95% CI, 1.461-10.35; p = 0.007) and extended resection (OR, 3.03; 95% CI, 1.183-7.750; p = 0.021) LIMITATION OF THE STUDY:: This study is an observational retrospective study on selected patients (mainly a young population).
  
  
  CONCLUSIONS
  This study showed that perineal complications and extended resection are associated with poor functional results after pseudocontinent perineal colostomy. These data can help clinicians to better inform patients about the outcomes of this technique and to assist them in choosing the right reconstruction technique after abdominoperineal resection.
