INTRODUCTION
Deep infiltrating endometriosis penetrates the peritoneal surface beneath 5 mm. The bowel is affected in 3-37% of the cases.


OBJECTIVE
The aim of the authors was to analyze the results of the surgical procedures performed for bowel endometriosis.


METHOD
Between 2009 and 2020, 675 patients underwent bowel endometriosis surgery at the Department of Obstetrics and Gyanecology of Semmelweis University. Four surgical approaches were performed: shaving, discoid, segmental and NOSE resection.


RESULTS
182 shaving, 93 discoid, 130 NOSE and 270 segmental bowel resections were performed. Ultra-deep anastomosis was performed in 40 cases. The median operative time was 85 minutes, the shortest intervention lasted 25 minutes, the longest 585 minutes. The average operating time was 260 (± 161.3) minutes for the first, and 114 (± 47.0) minutes for the last ten operations. The average blood loss was 10 (± 20.3) mL. The average hospital stay was 6 (± 2.3) days. Serious surgical complication (Clavien-Dindo III or more severe) developed in 18 cases. In a total of 17 cases sigmoideo- or ileostomy were used. Conversion to laparotomy was necessary in 6 cases.


DISCUSSION
The same team performed all the interventions, which can show the effectiveness of the surgical techniques instead of the technique of individual surgeons. The complication rate is low in the case of an experienced surgical team, and the operating time decreases significantly in proportion to the number of operations performed.


CONCLUSION
Bowel endometriosis can be treated safely and effectively with both conservative (shaving or discoid) and radical (segmental or NOSE resection) approach. Orv Hetil. 2023; 164(9): 348-354.
