Transanal Endoscopic Microsurgery: The First 50 Cases


Transanal Endoscopic Microsurgery: The First 50 Cases

K Chip Farmer et al. ANZ J Surg. .


Background: Transanal endoscopic microsurgery is a form of minimally invasive rectal surgery first used at Cabrini Hospital in April 1997. This paper presents a prospective analysis of the first 50 cases with a median follow up of 33 months (range 20-48 months).

Methods: Prospective data was obtained from all cases between April 1997 and June 2000.

Results: Forty-nine patients (30 men and 19 women) underwent 50 procedures. Thirty-six had benign lesions and 14 malignant. The mean distance of the lower edge of the lesion from the anal verge was 8.7 cm. Three cases were converted to traditional transanal or transabdominal operations. Full-thickness excision was performed on 26 patients and the rectal wound was closed in 13 cases. The mean duration of transanal endoscopic microsurgery was 67 min (range 20-175), with a mean blood loss of 24 mL (0-300). The mean diameter and area of the fixed specimen was 3.7 cm (1.5-9.8) and 11.4 cm2 (0.8-18.9), respectively. Complications included postoperative fever (3), urinary retention (1) and per rectum bleeding (1). There was one death. The mean length of stay was 4 days. Histology confirmed complete excision in 39 (78%) cases and there have been two instances of local recurrence of adenoma (5%).

Conclusions: Transanal endoscopic microsurgery is an effective, safe and cost-beneficial procedure for local excision of selected lesions in the middle and upper thirds of the rectum.
