A 7-year-old girl had a chief complaint of an abdominal bulge from the navel to the lower abdomen. Ultrasound and MRI revealed a cystic mass originating from the left ovary, with some solid components, suggesting a mature ovarian cystic teratoma. Laparoscopic ovarian cystectomy was performed, and histopathological analysis revealed a mature teratoma. The patient was discharged on the third day after surgery, but after another three days, the patient experienced severe abdominal pain after eating lunch and visited the emergency room. An abdominal X-ray revealed a small amount of gas in the small intestine, and a contrast CT scan revealed that this was a postoperative change; the patient was admitted to the hospital. Vomiting continued after admission, and the patient began to complain of upper abdominal pain. Laparotomy was performed on the 10th postoperative day, and the small intestine was found to have been twisted 180 degrees clockwise. The Treitz ligament was not formed, and the ileocecal area, ascending colon, and right half of the transverse colon were not fixed to the retroperitoneal cavity. The cecum and ascending colon were fixed to the retroperitoneum, and the patient was discharged on the 12th day after the second operation. We report a case of small intestinal volvulus associated with mesenterium commune that developed immediately after laparoscopic ovarian cystectomy.
