Background: Transanal endoscopic microsurgery (TEM) is a minimally invasive technique for the excision of rectal lesions, with lower morbidity and mortality rates than open surgery. Following advances in laparoscopic colorectal surgery and endoscopic mucosal resection, this study evaluated the safety and efficacy of TEM in the treatment of complex rectal lesions. Methods: All patients were entered into a prospective database. Complex lesions were identified as high (more than 15 cm from anorectal margin), large (maximum dimension over 8 cm), involving two or more rectal quadrants, or recurrent. Results: Seventy-one lesions (13 carcinomas and 58 tubulovillous adenomas) were identified. The median duration of operation was 60 (interquartile range (i.q.r.) 30,80) min, with an estimated median blood loss of 0 (i.q.r. 0,10) ml. Median hospital stay was 2 (i.q.r. 1,3) days. One patient developed postoperative urinary retention and one returned with rectal bleeding that did not require further surgery. Two patients developed rectal strictures after operation that were dilated successfully. There was no recurrence of benign lesions during a median follow-up of 21 (i.q.r. 6·5,35) months. Conclusion: TEM is a safe technique with low associated morbidity, even when used to excise complex rectal lesions. As such it remains the treatment of choice for rectal lesions not requiring primary radical resection. Copyright © 2008 British Journal of Surgery Society Ltd. Published by John Wiley & Sons, Ltd.

Endoscopic transanal resection of rectal tumours using a urological resectoscope , still has a role in selected patients

COLORECTAL DISEASE, Issue 1 2005

Abstract Introduction Transanal resection of rectal villous adenomas or adenocarcinomas can be carried out using various modalities such as operative excision, fulguration, laser coagulation or cryotherapy. Transanal endoscopic microsurgery is currently not widely available. Transanal resection can provide effective palliation for locally advanced rectal tumours in patients unfit for abdomino-perineal excision of rectum. A urological resectoscope can be safely and repeatedly used to resect advanced primary or locally recurrent rectal rumours by colorectal surgeons with urological expertise. This study reports our experience of treating rectal lesions with endoscopic transanal resection (ETAR) using the urological resectoscope. Methods Patients were identified from one surgeons' prospectively collected operating data. Charts were retrieved and reviewed. Results Over a 13-year period a total of 43 ETAR procedures were carried out in 20 patients (11 males; mean age 74 years; range 54,92 years) using the urological resectoscope. Twelve (60%) patients had a single resection; 8 (40%) patients required more than one resection; the mean number of procedures per patient was 2.2 (range1,8). The median interval between resections for recurrent disease (excluding planned repeat resections) was 340 days (range 168,2337 days). Histopathology revealed rectal adenoma (with varying degrees of dysplasia) in 11 (55%) patients and adenocarcinoma in 9 (45%). The majority (30; 70%) of resections were carried out in patients with benign disease, with 13 (30%) in patients with rectal adenocarcinoma. Mean operating time per resection was 25 min. Thirteen (30%) resections were carried out under spinal anaesthetic. There was no procedure related mortality. There were no cases of haemorrhage, rectal perforation, ,TUR syndrome' or pelvic sepsis. No patients with benign disease subsequently developed an invasive carcinoma. Conclusions Accepting that this technique provides limited histopathological information regarding extent of resection and tumour clearance, our experience demonstrates that ETAR of rectal tumours using the urological resectoscope can provide a minimally invasive, effective and safe means of treating and palliating patients with benign and malignant rectal disease. There remains a place for this technique in selected patients. [source]
