N2 - Background Transanal endoscopic microsurgery (TEM) and transanal minimally invasive surgery (TAMIS) have been shown to improve the quality of transanal resections, allowing for improved visibility and access to the proximal rectum. This study compares the short-term outcomes between TEM and TAMIS among experienced colorectal surgeons. Method A retrospective review was conducted for TEM and TAMIS performed from 2012 to 2015 by local colorectal surgeons. Baseline patient demographics, operative variables, pathology results, and short-term outcomes were assessed. Results Sixty-nine patients were identified (40 TEM and 29 TAMIS). Patient demographics, tumor characteristics, operative variables, margin status, and postoperative complications were similar for both. Volume of resection was higher for TAMIS (P <.001). Lymph node retrieval was achieved in 17.2% of TAMIS cases compared with 0% of TEM (P =.01). Conclusions TAMIS appears to have equivalent indications and outcomes compared with TEM. TAMIS is associated with larger specimens and more frequent presence of mesorectal lymph nodes.
