Robotic Top-down Intersphincteric Resection

Summary

The present study is to develop the novel robotic surgical technique and enhance the surgery quality for the treatment of distal rectal cancer.

Eligibility

Inclusion Criteria:

* cT1-3 or yT 1-3 rectal adenocarcinoma whose low border was located below the anorectal sling (4 cm from anal verge), in which the required surgery meets the definition of ISR;
* Clinically Tumor-Node-Metastasis (TNM) stage I-III rectal adenocarcinoma;
* Curative and elective surgery;
* American Society of Anesthesiology (ASA) class Ⅰ to Ⅲ patients;
* Age between 20 and 75 years.

Exclusion Criteria:

* cT4 adenocarcinoma, i.e., the rectal cancer invaded to external sphincter or adjacent pelvic organs;
* Evidence of distant metastasis;
* Primary tumor mass≧8 cm in diameter;
* Morbidly obese patients, i.e., body mass index (BMI) ≧ 40 kg/m2 ;
* Previous major surgery of low upper abdomen;
* The adenocarcinoma has invaded to lateral pelvic side wall requiring a lateral pelvic lymph node dissection. (7) Patients with poor anorectal function (Wexner incontinence Score≧ 10)
