A Stepwise Approach to Transanal Endoscopic Microsurgery for Rectal Cancer Using a Single-Incision Laparoscopic Port
Annals of Surgical Oncology, 05/04/2012
Smith RA et al. – Transanal endoscopic microsurgery (TEM) using a single–incision laparoscopic (SILS) port is an effective technique for the local excision of mid–upper rectal cancer in well–selected patients.
Methods- Authors 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 uT1 disease with no lymphadenopathy.
- He opted for local excision and underwent TEM.
- The 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.
- 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.
