Abstract
Transanal endoscopic microsurgery (TEM) was introduced in 1983 as an alternative to radical proctectomy for the management of rectal adenomas unsuitable for endoscopic or standard transanal resection. Since, its indications have progressively broadened to early rectal cancer. This review article will assess the role of TEM for T1 rectal cancer management, along with its operative and long-term results.

Abstract
INTRODUCTION:
Transanal endoscopic microsurgery (TEM) allows locally complete resection of early rectal cancer as an alternative to conventional radical surgery. In patients with unfavourable post-TEM histology, salvage surgery can be performed. The aim of this study was to evaluate the results of early radical surgery after TEM for rectal cancer.
MATERIAL AND METHODS:
From 1997 to 2010, 86 TEM procedures were performed in 79 patients due to rectal cancer. Early salvage surgery was performed in 25 patients. Data were obtained from the patients' charts and reviewed retrospectively. Perioperative data and oncological outcome were analysed.
RESULTS:
No patients received preoperative chemotherapy. The median time to salvage surgery was 37 days. Five patients underwent laparoscopic surgery. The median operative time was 165 min (range: 101-341 min, 95% confidence interval (CI): 156-214 min) and the median blood loss 275 ml (range: 0-1,275 ml, 95% CI: 232-530 ml). The 30-day mortality was 8% (95% CI: 1-19%, n = 2). Intraoperative perforation occurred in 20% (95% CI: 3-37%, n = 5). The median number of harvested lymph nodes was 12 (range: 3-25, 95% CI: 9-14) and the median circumferential resection margin (CRM) was 10 mm (range: 0-20 mm, 95% CI: 5-12 mm). Only one patient (4%, 95%CI: 1-12%) had a positive CRM. The median follow-up time was 25 months (range: 3-80 months). There was no local recurrence. Distant metastasis occurred in 4% (95% CI: 1-12%, n = 1).
CONCLUSION:
Early salvage surgery after TEM seems to be safe despite a high risk of specimen perforation during the operation.

Local resection for rectal tumors: comparative study of transanal endoscopic microsurgery vs. conventional transanal excision - the experience in China.

Department of General Surgery, RuiJin Hospital affiliated to Shanghai Jiaotong University School of Medicine, Shanghai, China.
Abstract
BACKGROUND/AIMS:
To compare the operative range,safety and therapeutic effect of local resection of rectal tumors by using transanal endoscopic microsurgery and conventional transanal excision.
METHODOLOGY:
We reviewed data from 76 patients treated using conventional TAE during the period from January 2003 to July 2006 and 53 patients treated using TEM during the period from September 2006 to February 2010 in the Ruijin Hospital affiliated with the Shanghai Jiaotong University School of Medicine.
RESULTS:
Age, gender, tumor size, blood loss and postoperative hospital stay were similar in the 2 groups. The median distance from the anal verge was significantly higher in the TEM group than in the TAE group. Operation time was significantly longer in the TEM group than in the TAE group.During the median follow-up of 40 months, the LRR in the TEM group was lower than that in the TAE group,especially for tumors that are larger (>3cm) and located higher (>8cm from the anal verge) and pT1 carcinomas.
CONCLUSIONS:
TEM is a safe, effective and minimally invasive surgical technique for the treatment of early rectal neoplasms. Compared to conventional TAE,TEM has a broader operative range and a better therapeutic effect.

A stepwise approach to transanal endoscopic microsurgery for rectal cancer using a single-incision laparoscopic port.

Abstract
BACKGROUND:
Radical rectal resection with total mesorectal excision is the current standard of care for the operative treatment of rectal cancer. Local excision is an acceptable alternative in selected patients with early disease (T(is)0-T(1)) and low-risk features, in whom radical resection may be associated with unacceptably high morbidity. With recent data demonstrating favorable results in well-selected patients, the role of local excision for rectal cancer is expanding.1 (,) 2 Transanal endoscopic microsurgery (TEM), which requires the use of an operating anoscope, has been used for the local excision of mid-upper rectal tumors. We describe an alternative approach to TEM for rectal cancer.
METHODS:
We present a stepwise technique for TEM using a single-incision laparoscopic (SILS) port. The patient is a 64 year-old male with a right anterolateral rectal polyp 7 cm from the anal verge, which on snare polypectomy demonstrated in-situ carcinoma with positive margins. Endoscopic ultrasound demonstrated uT(1) disease with no lymphadenopathy. He opted for local excision and underwent TEM. Our stepwise approach includes: (1) delineation of excision margins, (2) full thickness incision of the rectal wall, (3) circumferential dissection, and full thickness excision, and (4) suture repair.
RESULTS:
The procedure was performed without intraoperative or postoperative complications. Final pathology revealed in-situ carcinoma with widely negative margins. At 1- and 3-week follow-up visits, the patient was pain free with normal bowel activity and no rectal bleeding or genitourinary dysfunction.
DISCUSSION:
TEM using a SILS port is an effective technique for the local excision of mid-upper rectal cancer in well-selected patients.
