Full thickness SITE resection for a failed TAMIS bulky sessile lesion – case report

Abstract Text A 43yo woman underwent TAMIS for the excision of a bulky sessile rectal lesion. The procedure was interrupted for the development of mediastinal enphisema. At follow-up colonoscopy 3 months after, a residual 50 mm rectal lesion was identified, located in an area of severe fibrosis. SITE ESD was selected as the preferred therapeutic approach. During the procedure, full-thickness muscle dissection was required as it was not possible to excise the adenomatous tissue from the scar. A clip-and-rubber band traction method was employed to facilitate the resection. Resection time was 270 minutes under operator-delivered conscious sedation. The deepest parts of the resection site were closed with clips. The patient was safely discharged home 48 hours after the procedure, and no complications were noted. Histopathological examination revealed LGD with HGD, confirming an R0 resection.
