Total mesorectal excision (TME) is the standard surgical principle in the treatment of rectal cancer. However, in recent years, there has been an increasing debate about how to obtain better results in circumferential margin (CRM) and distal margins of the surgical specimen. The CRM and distal margin involvement rates have been linked to local recurrence and disease-free survival rates. In this study, we compared three surgical techniques for the treatment of lower rectal cancer. ⋯ TaTME provides surgeons with a novel and effective method to treat lower rectal cancer. In the short-term outcomes, TaTME achieved better pathological results and disease free survival than OpTME but not significantly superior to LaTME. Further studies are necessary to evaluate the long-term oncological results.

Meta Analysis Comparative Study
Short-term outcomes of robotic-assisted right colectomy compared with laparoscopic surgery: A systematic review and meta-analysis.
To assess the clinical efficacy and safety of robotic-assisted right colectomy (RRC) with conventional laparoscopic right colectomy (LRC) by performing a systematic review and meta-analysis of the published studies. All published literature for comparative studies reporting preoperative outcomes of RRC and LRC were searched. We searched the databases included Cochrane Library of Clinical Comparative Trials, MEDLINE, Embase, Web of Science and Chinese Biomedical Database (CBM) from 1973 to 2018. ⋯ However, operation times [MD = 43.61, 95% CI: 39.11 to 48.10, P < 0.00001] were longer for RRC than for LRC. Compared to LRC, RRC was associated with reduced estimated blood loss, reduced postoperative complications, longer operation times. Recovery of bowel function and other perioperative outcomes were equivalent between the two surgeries.

Comparative Study
Supra-aortic vessel reconstruction in total arch replacement for acute type A dissection: Comparison of en bloc and separate graft techniques.
To compare the outcomes of the en bloc and branched graft techniques for supra-aortic vessel reconstruction in total arch replacement (TAR) for acute type A aortic dissection (ATAAD). ⋯ The modified en bloc technique could achieve comparable early and mid-term outcomes to the branched graft technique in patients undergoing TAR for ATAAD. This approach may be an alternative technique for ATAAD patients with intact supra-aortic arch vessels.

Post-operative pancreatic fistula (POPF) is one of the most common and serious complications after pancreaticoduodenectomy (PD). The aim of this study is to retrospectively compare clinically relevant (CR) POPF and other complications after pacreaticojejunostomy (PJ) after modified Kakita (m-Kakita) or modified Blumgart (m-Blumgart) anastomoses without stenting in a single institution. ⋯ This retrospective single-center study demonstrated that the modified Blumgart method without pancreatic duct stenting was associated with a lower rate of CR-POPF.
