Abstract
BACKGROUND
Transanal total mesorectal excision (taTME) is a new technique with many potential technical advantages. Laparoscopy-assisted taTME is a combination of transabdominal taTME and transluminal endoscopic surgery taTME. Laparoscopy-assisted taTME is a combination of techniques such as minimally invasive surgery, intersphincter-assisted resection, natural orifice extraction, ta minimally invasive surgery, and ultralow-level preservation of the anus.
AIM
To verify the feasibility and safety of an innovative technique of taTME for treatment of cancer located in the lower rectum.
METHODS
From January 2016 to March 2018, we attempted to perform laparoscopy-assisted taTME surgery in 24 patients with lower rectal cancer.
RESULTS
The new technique of laparoscopy-assisted taTME was successfully performed in all 24 patients. Mean operating time was 310.0 min and mean intraoperative blood loss was 69.1 mL. The mean time to passing of first flatus was 3.1 d, and mean postoperative hospital stay was 9.2 d. Two patients were given postoperative analgesics due to anal pain. Twenty-three patients were able to walk in first 2 d, and five patients had postoperative complications.
CONCLUSION
Laparoscopy-assisted taTME is suitable for selected patients with lower rectal cancer, and this technique is worthy of further recommendation.
Core Tip: We report our initial experience with transanal total mesorectal excision for distal rectal cancer, with a 100% success rate of intraoperative preservation of the anal sphincter. The patients in this study had a narrow pelvis, mild obesity, and distal rectal lesions, making the operation extremely difficult. Most of the patients had undergone neoadjuvant chemoradiation. We believe that this procedure is feasible for selected patients with lower rectal cancer, and is worthy of further recommendation.
