Laparoscopic segmental resection of the rectum for upper rectal intussusception caused by a giant rectal lipoma: A case report

RATIONALE: Colonic lipomas are rare benign tumours, usually without any symptoms, and most occur in the caecum and ascending colon. We describe a patient with upper rectal intussusception caused by a giant rectal lipoma; no similar report of this type of case has been published. PATIENT CONCERNS: We report the case of a patient who suffered from repeated bloody stools. A wide pedicle polyp (size, 6.5 × 4.5 × 3.5 cm) was detected at the 15th centimetre of the anal canal via an electronic colonoscope. At the initial part of the rectum, intussusception caused by a 6.5-cm fat-density mass was observed via abdominal contrast-enhanced computed tomography. DIAGNOSIS: Upper rectal intussusception caused by a giant rectal lipoma. INTERVENTIONS: Due to the large size of the polyp, an endoscopic polypectomy could not be performed. We performed laparoscopic segmental resection of the rectum (with preservation of the left colic artery [LCA]). OUTCOMES: The patient was discharged on the 7th postoperative day without any complications, was monitored on a regular basis at our outpatient department and was free of symptoms at a 3-month follow-up visit. LESSONS: Laparoscopic segmental resection of the rectum with LCA preservation is safe and feasible for the treatment of upper rectal intussusception caused by a giant rectal lipoma.
