Resección transmural endoscópica de adenoma colónico residual con fibrosis / Endoscopic full-thickness resection of residual colonic adenoma with fibrosis

Resumen La resección transmural endoscópica es una técnica que permite la resección en bloque de lesiones colónicas en pacientes en los cuales han fracasado los métodos endoscópicos convencionales como la resección mucosa endoscópica o la disección submucosa endoscópica. Presentamos el caso de un hombre de 75 años con antecedentes de adenoma de colon con fibrosis debido a dos intentos previos fallidos de resección endoscópica en otra institución. Realizamos con éxito el procedimiento de resección transmural endoscópica evitando así una cirugía.

Abstract Endoscopic full-thickness resection is a technique that allows in block resection of colonic lesions in patients in whom conventional endoscopic methods such as endoscopic mucosal resection or endoscopic submucosal dissection have failed. We present a case of a 75-year-old man with history of a difficult-to-resect colon adenoma. He had undergone two previous failed attempts of endoscopic mucosal resection due to non-lifting sign in another center. We successfully performed an endoscopic full-thickness resection procedure, avoiding unnecessary surgery.

Full-Thickness Resection Device for Complex Colorectal Lesions in High-Risk Patients as a Last-Resort Endoscopic Treatment: Initial Clinical Experience and Review of the Current Literature

The full-thickness resection device (FTRD) is a novel endoscopic device approved for the resection of colorectal lesions. This case-series describes the device and its use in high-risk patients with colorectal lesions and provides an overview of the potential indications in recently published data. Between December 2014 and September 2015, 3 patients underwent endoscopic full thickness resection using the FTRD for colorectal lesions: 1 case for a T1 adenocarcinoma in the region of a surgical anastomosis after recto-sigmoidectomy, 1 case for a non-lifting colonic adenoma with low-grade dysplasia in an 89-year old patient and 1 for a recurrent adenoma with high-grade dysplasia in a young patient with ulcerative rectocolitis who was under immunosuppression after renal transplantation. Both technical and clinical success rates were achieved in all cases. The size of removed lesions ranged from 9 to 30 mm. Overall, the most frequent indication in the literature has been for lifting or non-lifting adenoma, submucosal tumors, neuroendocrin tumors, incomplete endoscopic resection (R1) or T1 carcinoma. Colorectal FTRD is a feasible technique for the treatment of colorectal lesions and represents a minimally invasive alternative for either surgical or conventional endoscopic resection strategies.
