Long-term outcomes after Natural Orifice Specimen Extraction versus conventional laparoscopy-assisted surgery for rectal cancer: a matched case-control study.

ABSTRACT:

Purpose

The aim of this study was to compare the long-term outcomes of total laparoscopic surgery with Natural Orifice Specimen Extraction (NOSE) with those for conventional laparoscopy (CL)-assisted surgery for treating rectal cancers.

Methods

We reviewed the prospectively collected records of 844 patients (163 NOSE and 681 CL) who underwent curative surgery for mid- or upper rectal cancers from January 2006 to November 2012. We applied propensity score analyses and compared oncological outcomes for the NOSE and CL groups in a 1:1 matched cohort.

Results

After propensity score matching, each group included 138 patients; the NOSE and CL groups did not differ significantly in terms of baseline clinical characteristics. The median follow-up was 57.7 months (interquartil
