ABSTRACT
<p><b>OBJECTIVE</b>To explore the applicable value of transanal total mesorectal excision (taTME) in male low rectal cancer patients with narrow pelvis-"difficult pelvis", which remains difficult for both open and laparoscopic sphincter-saving operations.</p><p><b>METHODS</b>Clinical data of male low rectal cancer patients diagnosed by pathology undergoing taTME between June 2016 and January 2018 at Peking University Cancer Hospital were collected. A retrospective cohort study was performed. Patients were selected according to the following criteria (1) low rectal cancer, the distance between inferior margin of tumor and anal verge ≤5 cm; (2) the distance between two sciatic tubercles <5 cm; (3) body mass index (BMI) >25 kg/m; (4) tumor horizontal diameter ≤4 cm. Operation time, intraoperative blood loss, postoperative hospital stay, postoperative complications and anal function were analyzed.</p><p><b>RESULTS</b>A total of 20 patients were included in this study. All the patients received preoperative neoadjuvant chemoradiation and hybrid transabdominal and transanal surgery. The median BMI was 27.7(26.2-36.4) kg/m; the median distance between two sciatic tubercles was 92.5 (78-100) mm; the median distance between the inferior margin of tumor to the anal verge was 4 (2-5) cm; the median operation time was 302 (215-402) min; the median intraoperative blood loss was 100 (50-200) ml; the median postoperative hospital stay was 9 (5-15) d. Postoperative complications occurred in 5 patients (25%), including 3 pelvic infection, 1 intestinal obstruction, 1 anastomotic leakage receiving sigmoid colostomy. There was no perioperative death. Sphincter-preservation rate was 100%. Nineteen patients received anal manometry 1 month after operation with normal resting pressure (41.5±8.6) mmHg and squeeze pressure (121.0±11.6) mmHg. All the patients were followed up to March 2018, and the median follow-up time was 4.5 months. Only 1 patient had supraclavicular lymph node metastasis and no local recurrence was found.</p><p><b>CONCLUSIONS</b>The safety of transanal total mesorectal excision for male patients with low rectal cancer and difficult pelvis is acceptable. TaTME is helpful to preserve the anal sphincter.</p>
