Abstract
Single port transanal excision for local treatment of rectal lesions Background: Since 2009, transanal minimally invasive surgery (TAMIS) is increasingly used as an alternative to local excision and transanal microscopic excision (TEM) for rectal lesions located in the mid and superior third. The clinical benefits of the technique are being evaluated. Aim: To establish the feasibility, quality of excision and short term results of single port transanal excision for rectal lesions. Patients and Methods: Analysis of a prospective series of patients subjected to single port transanal excision. Patients had benign or malignant lesions located in the mid or superior third of the rectum. Those with a diagnosis of adenocarcinoma were excluded. Results: The transanal resection using the SILS Port ® was completed in 11 patients aged 21 to 86 years (eight women). The American Society of Anesthesiologists (ASA) classifi cation of patients was two and their body mass index was 24 ± 3.1 kg/m 2 . The lesion distance from the anal margin ranged from 5 to 10 cm. The surgical time was 47 min and hospital stay was 2.8 days. One patient was converted to conventional transanal surgery and two patients had self-limited episode of hematochezia. Conclusions: TAMIS is a feasible technique and with promising results in selected patients.
