Background:
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.
Methods:
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.
Results:
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.
Conclusions:
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.
