Trans-Anal Minimally Invasive Surgery vs Trans-Anal Endoscopic Microsurgery: A Comparative Case Control Matched-Pairs Analysis

Since its introduction in the early 1980s, Trans-anal Endoscopic Microsurgery (TEM) has become the standard treatment for benign rectal lesions not amenable to endoscopic excision and for low risk early rectal cancers. In 2010 Trans Anal Minimal Invasive Surgery (TAMIS), which uses a disposable platform, was introduced to simplify the technique and to increase its popularity. The aim of the present study was to compare TEM and TAMIS in terms of incidence of R1 resection, fragmentation, perioperative operative complication.

ConclusionPrimary postoperative pulmonary complications affected 1.3% of patients undergoing MIS for colon or rectal cancer. The novel predictive risk score showed good discrimination and may help to identify patients who may benefit from perioperative optimization.

CONCLUSION: A hybrid robotic transanal minimally invasive surgery approach allows for complete resection of very large polyps, which would otherwise be extremely challenging with standard transanal approaches. See Video at http://links.lww.com/DCR/B231.

This study aims to analyze prospectively collected data from a large Australasian colorectal cancer database. DESIGN: This is a retrospective cohort study using propensity score matching. SETTING: This study was conducted using data supplied by the Bi-National Colorectal Cancer Audit. PATIENTS: A total of 3451 patients who underwent open (n = 1980), laparoscopic (n = 1269), robotic (n = 117), and transanal total mesorectal excision (n = 85) for rectal cancer were included in this study. MAIN OUTCOME MEASURE: The primary outcome was positive margin rates (circumferential resection margin and/or distal resection ...

This study was conducted in a tertiary referral center. PATIENTS: All consecutive patients undergoing redo pelvic surgery after low anterior resection for rectal cancer between January 2005 and March 2018 were included. INTERVENTIONS: Redo surgery was divided into redo anastomosis and intersphincteric completion proctectomy. Transanal minimally invasive surgery procedures since November 2014 were compared with the conventional approach. MAIN OUTCOME MEASURES: Primary end points were procedural characteristics and 90-day major complications. RESULTS: In total, 104 patients underwent redo surgery; 47 received a r...

Clinics in Colon and Rectal Surgery DOI: 10.1055/s-0039-1698395Transanal total mesorectal excision (taTME) is the culmination of major developments in rectal cancer management and minimally invasive surgery. This surgical breakthrough holds great promise and excitement for the care of the rectal cancer patient. We would be remiss in discussing taTME to not acknowledge the role of transanal abdominal transanal proctosigmoidectomy, transanal endoluminal microsurgery, laparoscopy, and natural orifice transluminal endoscopic surgery that got us to this modern day explosion of the taTME approach. In this article, we detail and ...

AbstractColorectal cancer remains the third most common cancer effecting adults. Surgical guidelines recommend transanal excision of early rectal neoplasia up to 8  cm from the anal verge. A retrospective review of two novel approaches for transanal robotic local excision with R0 resections of rectal cancers which was, on average, higher than 8 cm. Twenty-one cases of robotic assisted transanal surgery for early stage disease (T0–T1, N0) were reviewed. The first 10 cases performed with the da Vinci® Si robotic platform between 2013 and 2016, and the first 11 cases performed using the Flex® Medroboti...

CONCLUSIONS: Robotic transanal minimally invasive surgery is a safe, oncologically effective surgical approach for rectal polyps and early rectal cancers. It offers the oncologic benefits and perioperative complication profile of other transanal minimally invasive surgical approaches but also enhances surgeon ergonomics and provides an efficient transanal rectal platform.

Authors: Kim MJ, Oh JH Abstract The lateral lymph node dissection (LLND) is still a subject of great debate as to the appropriate treatment for patients with mid to low advanced rectal cancer. The guidelines of the Japanese Society for Cancer of the Colon and Rectum recommend a LLND for patients with T3/4 rectal cancer below the peritoneal reflection. However, in most Western countries, a routine LLND is not recommended unless a node or nodes are clinically suspicious for metastasis. Even after preoperative chemoradiotherapy (CRT), an 8% to 12% lateral pelvic recurrence was noted. The size of the lateral lymph node...
