Curative endoscopic treatment of intussusception due to a giant colonic lipoma using a wedged balloon and ligation with detachable snares

Pedunculated colonic lipoma causing adult colo-colic intussusception: A case report and literature review

INTRODUCTION

Colo-colonic intussusception (CI) in adults is rare, usually caused by malignant conditions. Nonmalignant tumors, like colonic lipomas (CLs), can also be an underlying cause.

CASE REPORT

We report an unusual case of a 62-year-old man admitted to the emergency department with acute abdominal symptoms. The CT scan confirmed the colonic obstruction, causing significant distention in the transverse and right colon. It also revealed an intraluminal pedunculated colonic mass with fatty density. Peroperatively, a descending colon intussusception was noted. We performed a left colon resection with a double colostomy on the left flank. The postoperative follow-up was uneventful. Pathologic examination of the surgical specimen revealed two lipomas. One of them was pedunculated and protruded into the colonic lumen causing the intussusception.

DISCUSSION

We conducted a literature review of adult CLs complicated by CI, covering the period from January 1900 to June 2024, including 203 cases. We excluded lipomas exclusive to the small intestine and ileocecal valvula. Our analysis focused on the clinical and pathological characteristics of these cases, as well as the available management options.

CONCLUSION

Colonic intussusception due to lipomas are uncommon with a challenging preoperative diagnosis despite the evolution of imaging procedures. We aimed by our case to highlight such pathology and to study its features and the possibilities of its management.

Endoscopic treatment of intussusception due to small intestine polyps in patients with Peutz-Jeghers Syndrome

Background and study aims  Intussusception caused by intestinal polyps in patients with Peutz-Jeghers syndrome usually requires laparotomy. Patients following successful endoscopic reduction using double-balloon endoscopy (DBE) have been reported. The aim of this study was to evaluate the feasibility of endoscopic treatment of intussusception. Patients and methods  We retrospectively reviewed patients who underwent DBE for intussusception due to small intestine polyps in patients with Peutz-Jeghers syndrome from January 2004 to June 2020. Results  Twenty-seven (antegrade 22, retrograde 5) DBEs were performed in 19 patients with 25 sites of intussusception identified during the study period. If the intussusception remained once the endoscope reached the site, endoscopic reduction of the intussusception was performed as needed (15 sites). Ultimately, endoscopic resections (8 sites) or ischemic polypectomies (16 sites) of the polyp causing the intussusception were completed at 24 sites. Only one site could not be treated endoscopically and was treated surgically. The final per-site and per-patient success rates of endoscopic treatment were 96 % (24/25) and 95 % (18/19) respectively. Two patients developed mild acute pancreatitis and one patient developed intussusception after the procedures, both of which were treated non-operatively. Conclusions  Endoscopic treatment of intussusception is feasible to avoid laparotomy in patients with Peutz-Jeghers syndrome.

Intussusception related to transverse colonic lipoma: a case report and review of the literature

Lipomas are rare and benign colonic soft tissue lesions derived from mature adipocytes. Their poor clinical expression usually leads to a coincidental discovery during procedures like colonoscopy, imagery, surgery or autopsy. Due to their small size, a simple observation would usually be recommended. However, colonic lipomas (CLs) with clinical symptoms or signs including abdominal pain, nausea, vomiting, diarrhea, anaemia or even intussusception would need invasive treatment. It is recommended to perform surgery to treat CLs that are >2 cm. Endoscopic procedures could be an interesting alternative for the future but would still require further investigation. We report the case of a 30-year-old patient with transverse CLs leading to obstruction of the descending colon by intussusception and continue by presenting a review of the current literature.
