Endometriosis of rectosigmoid colon mimicking gastrointestinal stromal tumor

Abstract

Endometriosis is defined as the growth of functional endometriotic gland and stroma outside uterine cavity. Although it is common in women of reproductive age, extragenital endometriosis is considerably rare. Due to the frequent localization at the rectosigmoid junction in the gastrointestinal system, endometriosis may manifest with abdominal pain, constipation, and rectal bleeding. Gastrointestinal stromal tumor is the most common mesenchymal tumor of the gastrointestinal system and develops from muscularis propria. Its extraluminal component is prominent. In this study, we report a rare case of a 37-year-old patient who was operated with laparoscopic colon resection for a malignant-appearing submucosal mass with indistinct borders at the rectosigmoid junction that received the final diagnosis in histopathological examination. Endometriosis should be considered in the differential diagnosis of non-specific gastrointestinal symptoms in female subjects of reproductive age as the one reported here.

Influencing Factors of Gastrointestinal Function Recovery after Gastrointestinal Malignant Tumor

“…Because ERAS is an operation process gradually expanded on its core concepts (such as preoperative education and evaluation, avoiding intestinal preparation, preventing thrombosis and infection, perioperative anesthesia management, preventing intraoperative hypothermia, early pulling out of the gastric tube, early eating after operation, etc. ), it can be observed that there are differences in operation processes between different diagnosis and treatment centers, but similar results can be achieved in the end [ 8 , 9 ].…”

Letter to: Endometriosis of the rectosigmoid colon mimicking gastrointestinal stromal tumor

“…We would like to congratulate the authors for publishing such an informative and interesting article (1). We totally agree with the authors to proceed with various modalities and evaluation in this patient who presented with pelvic pain and abdominal bloatedness as it is not easy to diagnose rectosigmoid endometriosis solely by history and physical examination (2,3).…”
