HYPOTHESIS: Single-port laparoscopic rectal surgery can be performed using the principles of oncologic surgery in institutes experienced in laparoscopy with the advantages of minimally invasive surgery. DESIGN: Sphincter-saving mesorectal excision in 4 human cases via a single laparoscopic port. SETTINGS: A university hospital and a private hospital. PATIENTS: A series of 4 patients who underwent single-port laparoscopic sphincter-saving rectal resection for rectal cancer. Two of them were total and 2 were partial mesorectal excisions. INTERVENTIONS: An umbilical incision was made to place the multichannel single port. The sigmoid colon was hung to the left lateral abdominal wall using an intracorporeal stitch passing through its appendices epiploicae to achieve medial dissection and vascular ligation. The mesorectum was sharply dissected down to the pelvic floor. Endoscopic linear roticulating staplers were used to divide the rectum and proximal colon. A specimen was retrieved using an extraction bag through the umbilicus. Anastomosis was performed using a circular stapler, or pull-through hand-sewn anastomosis was performed. MAIN OUTCOME MEASURES: Duration of the operation, length of hospital stay, surgical complications, wound size, and histopathologic data. RESULTS: There were no perioperative or postoperative complications. Mean operative time was 347 minutes (range, 240-480 minutes). Mean hospital stay was 4.25 days (range, 4-5 days). Mean wound size was 3.5 cm (range, 3-4 cm). Mean number of harvested lymph nodes was 15 (range, 8-28). CONCLUSIONS: With the help of sophisticated surgical technology and techniques, single-port laparoscopic surgery for rectal cancer will be feasible while also maintaining oncologic principles and patient safety.
