Abstract

BackgroundIntestinal endometriosis is a common benign disease among menstruating women that affects the intestinal tract.Case presentationThis case report presents seven Japanese cases of intestinal endometriosis with colorectal cancer treated by laparoscopic surgery. Five of the seven cases reported here are women presenting with bowel obstruction due to colorectal endometriosis with colorectal cancer. It can be confused with serious lesions such as advanced colorectal cancer with peritoneal involvement or invasion of adjacent organs (T4).ConclusionsTherefore, we should consider the probability that the cause of bowel obstruction is not T4 but intestinal endometriosis. For surgical treatment, we recommend laparoscopic surgery for colorectal resection because of its benefits of differential diagnosis of T4, preserving fertility, and preventing excessive surgical stress. We performed laparoscopic resection in seven patients with intestinal endometriosis and colorectal cancer. These cases demonstrate the difficulty of establishing a differential diagnosis of intestinal endometriosis with colorectal cancer from T4.

Summary

Conclusions

Intestinal endometriosis with colorectal cancer is a relatively rare disease and is difficult to distinguish from T4 cancer. We should consider the probability that the cause of bowel obstruction is not T4 but intestinal endometriosis. Laparoscopic resection of the rectum or colon for intestinal endometriosis can be performed safely and effectively. We consider that our laparoscopic approach with intraoperative endoscopy as a standardized technique for this disease will be increasingly indicated
