A Pilot Study of Laparoscopy-Assisted Transanal Endoscopy Rectosigmoid Resection for Rectal Cancer

Subjects will have their rectal cancer removed using a technique combining surgery through
the anus and standard laparoscopy. At the end of the procedure, the rectum will be removed
though the anus, the bowel will be re-connected to the anus, and a temporary diverting stoma
will be created, which is standard of care following surgery for this type of cancer.

Inclusion Criteria:

- Eligible to undergo standard open or laparoscopic low anterior resection with a
temporary diverting stoma

- Node negative (N0), T1 (high risk features), T2 and T3 rectal cancer on pelvic MRI

- Closest distance between tumor edge and mesorectal fascia 5mm or more based on pelvic

- Rectal cancer located 4-12 cm from the anal verge

- ECOG performance status 2 or less

Exclusion Criteria:

- Metastasis

- Obstructing rectal cancer

- Synchronous colon cancer

- T3 rectal cancer not treated preoperatively with full-course chemoradiation

- Pregnant or breast-feeding

- Receiving any other study agents

- Fecal incontinence

- History of prior colorectal cancer

- History of inflammatory bowel disease

- History of pelvic radiation

- Prior pelvic surgery or multiple abdominal procedures

- BMI > 30
