A minilaparotomy for specimen extraction during laparoscopy occasionally results in postoperative wound complications. We have performed a totally laparoscopic resection for early colorectal cancer using the natural orifice specimen extraction technique.


From 2008 to 2013, we have performed a totally laparoscopic resection for clinical stage I and IIA low sigmoid colon and rectal cancers. A prospectively maintained database was reviewed to assess the outcomes after surgery.


In total, 40 patients had high anterior resections using transanal specimen extraction, and 32 patients had low anterior resections with transanal pull-through. Eight patients (11%) reported conversion to conventional laparoscopic colorectal resections; anastomotic leakages occurred in 4 patients (5.6%). No mortality or cancer recurrence was observed during 42.5±16.2 months of follow-up.


One natural orifice specimen extraction technique, known as transanal specimen extraction, has emerged as a promising form of totally laparoscopic surgical intervention for early-stage cancers of the low sigmoid colon and rectum.
