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.
