Abstract: Objective：To explore the clinical manifestation, diagnosis and treatment of bowel endometriosis (BE). Methods：A total of 21 patients with BE from February 2014 to January 2018 were recruited. The clinical characters, diagnosis, treatment and outcomes of 21 cases were summarized and analyzed. Results：The intestinal manifestation in 21 patients included diarrhea, constipation, defecation pain, and so on. Seven patients (33.33%) underwent the laparoscopic superficial excision while the remaining 14 patients (66.67%) underwent the laparoscopic colorectal resection. There were no operative complications of intestinal fistulas, anastomotic bleeding, anastomotic fistulas and anastomotic stenosis. The other complications included small-bowel obstruction (1 case, 4.76%), urinary retentions (2 cases, 9.52%) and pelvic infection (1 case, 4.76%). The scores of visual analogue score (VAS) of dysmenorrheal, dyspareunia, defecation pain and hypogastralgia were significantly lowered (P＜0.05). The intestinal symptoms, such as diarrhea and constipation, were remitted. Conclusions：The clinical manifestation of BE is not typical, so the diagnosis of BE is difficult. Laparoscopic treatment of BE can effectively remitted the endometriosis-related symptoms, suggesting that the laparoscopy is the first choice of surgical treatment.
