title: [Technical questions of the transrectal specimen extraction].
abstract: BACKGROUND
  During laparoscopic partial colectomy the specimen can be extracted transrectally. This technique decreases the invasiveness of the surgery, because the abdominal wall incision is avoided. Premises of a new surgical technique are precise technical description as well as a favourable balance of advantages and disadvantages. In this paper the authors review the technique they apply and analyse their first results.
  
  
  METHODS
  45 laparoscopic bowel resections were performed by a multidisciplinary team between 16th April 2014 and 1st November 2015. Indication of surgery was endometriosis, and the specimen was extracted transrectally in 11 patients. Having ligated both bowel ends proximal and distal to the section infiltrated with endometriosis, and the proximal bowel secured with a laparoscopic bulldog. Then the bowel was resected and the specimen was extracted in a camera bag transrectally. A purse-string suture was placed into the proximal bowel end, and the anvil of the circular stapler--which was introduced transrectally--was inserted into the bowel. After closing the rectal stump, the anastomosis was performed with a circular stapler. We used this technique when the upper third of the rectum or sigmoid colon was infiltrated with endometriosis.
  
  
  RESULTS
  The difference between the operation time of the two techniques (transabdominal vs. transrectal specimen extraction: 108 min vs. 118 min) was not significant. There was not difference in the WBC count between the first and second postoperative day, and there was not any anastomosis leakage detected either.
  
  
  CONCLUSIONS
  By using the above technique, postoperative infections could have been reduced to minimum. Transrectal specimen extraction did not increase postoperative complication The authors believe this is a safe way of specimen extraction after partial colectomy.
