Laparoscopy-assisted endoscopic mucosal resection in the colon: a preliminary report.
Endocopic mucosal resection of flat villous tumours or giant polyps (> 3 cm) may give rise to local complications such as haemorrhage or perforation because of the very thin wall of the colon, above all in the right half. Our aim was to evaluate whether laparoscopy-assisted endoscopic excision of flat villous tumours or giant polyps (> 3 cm) can be safely performed, avoiding critical septic complications and can also help in the selection of patients to be submitted to colonic resection without increasing morbidity or mortality. The procedure is a new minimally invasive therapeutic approach in selected cases with large, sessile or awkwardly located polyps. Unlike other techniques such as polypectomy, endoscopic mucosal resection completely removes the affected mucosa by resecting through the middle or deeper part of the submucosa. Another purpose of the procedure is to obtain specimens for accurate pathological staging. Our experience consisted in the treatment of two patients, one of whom with a laterally spreading tumour of the transverse colon with the suck and cut cap-assisted technique, and one with a large sessile polyp of the caecum with the lift and cut technique. The patients presented no complications and no recurrence was observed during the subsequent follow-up.
