Introduction: Transanal total mesorectal excision (taTME) has emerged as an alternative to open and laparoscopic techniques for mid and low rectal cancer. Reports published to date concluded that it is a safe and feasible technique. However, concerns exist about procedure related complications and if there are differences with what high quality randomized trials displayed for pure laparoscopic TME (37-54%). This study shows the morbidity outcomes of the largest series published of taTME.
Methods and Procedures: We analyzed the outcomes of all patients with mid and low rectal cancer treated by taTME at our hospital. All patients were entered in a prospectively collected database.
Results: One hundred eighteen patients (63.4%) with mid rectal tumor and 68 (36.6%) with low rectal tumor undergoing taTME were identified. Mean age was 65.0 years, 118 patients (63.4%) were male and 53.4% had a BMI>25Kg/m2. The majority of patients were classified as ASA II (82.0%) and ASA III (13.7%). Preoperative staging showed T1 in 3.3%, T2 in 20.1%, T3 in 67.9% and T4 and in 7.6%. Neoadjuvant treatment was given in 67.2%. Mean operative time was 147.8 min. Splenic flexure was mobilized in 38.3%, and a diverting ileostomy was performed in 85.4% of the cases. Anastomosis was created in 98.4% of the cases, of which 31.9% were handsewn and 68.1% stapled. Intraoperative complications occurred in 14 cases (8.1%). The 30-day postoperative complications rate was 36.8%: anastomotic leakage 7.7%, intraabdominal collection 7.1%, ileus 11.5%, urinary retention 4.4% and haemorrhage 2.7%. Of these complications 26.3% were classified as minor complications (Clavien-Dindo I-II) and 9.8% were classified as major complications (Clavien-Dindo III-IV). Reintervention was needed in 14 (7.7%) cases. Mean length of hospital stay was 8 days and the readmission rate was 11.7%. The three-month mortality rate was 1.1% (n=2): due to spontaneous oesophageal perforation (n=1) and myocardial infarction in the immediate postoperative period (n=1).
Conclusion: In a high volume center for the treatment of rectal cancer, the morbidity following taTME is similar to the one following pure laparoscopic TME.
