Transanal minimally invasive surgery using laparoscopic instruments of the rectum: A review

Abstract

Transanal minimally invasive surgery (TAMIS) was first described in 2010 as an alternative to transanal endoscopic microsurgery (TEM). The TAMIS technique can be access to the proximal and mid-rectum for resection of benign and early-stage malignant rectal lesions and also used for noncurative intent surgery of more advanced lesions in patients who are not candidates for radical surgery. TAMIS has a shorter learning curve, reduced device setup time, flexibility in instrument use, and versatility in application than TEM. Also, TAMIS shows similar results in a view of the operation time, conversion rate, reoperation rate, and complication to TEM. For these reasons, TAMIS is an easily accessible, technically feasible, and cost-effective alternative to TEM. Overall, TAMIS has enabled the performance of high-quality local excision of rectal lesions by many colorectal surgeons. As TAMIS becomes more broadly utilized such as pelvic abscess drainage, rectal stenosis, and treatment of anastomotic dehiscence, the acquisition of appropriate training must be ensured, and the continued assessment and assurance of outcome must be maintained.

Robot-assisted TAMIS: a systematic review of feasibility and outcomes

“…The peritoneal violations that occurred, happened all ≤ 12 cm from the anal verge. When comparing peritoneal violation, the present review identified seven cases (2.1%) while Kim et al [ 38 ] found peritoneal entry in 6.0% of the L-TAMIS procedures. The studies with peritoneal entry complications were all in the setting of full thickness excisions [ 34 ].…”

“…When evaluating the number of complications for patients undergoing R-TAMIS, 10.5% suffered from complications. A large L-TAMIS series of 200 cases by Lee et al [ 37 ] found a complication rate of 7%, and a recent published review on L-TAMIS with more than 1200 cases reported a complication rate of 18.4% [ 38 ].…”

“…Regarding oncologic pathology, a positive resection margin of 3.7% was found for R-TAMIS, which is slightly lower than for L-TAMIS with a positive resection margin of 7% to 8.6% [ 37 , 38 ]. Lesion fragmentation occurred in three cases (0.9%) of the R-TAMIS, which is lower than for L-TAMIS (5%) as reported by Lee et al [ 37 ].…”

From Transanal Total Mesorectal Excision to Transanal Transection with Single-Stapled: Evolution of Transanal Techniques

“…A recent review on TAMIS and other transanal and intraluminal approach reported a shorter operative time for TAMIS, while recurrence rate, complication, and quality of life are similar to those of TEM. 21…”

Colorectalis polypok és korai rákok sebészete – Elvárható standardok

“…E cikknek nem célja a TAMIS-technikának a hagyományos transanalis nyílt excisióval szembeni előnyeinek részletezése, elég legyen itt tényként megfogalmazni, hogy az analis csatorna felső széle felé terjedő, azaz rectum polypok esetében a TEM/TAMIS technika minden minőségi mutatóban előnyösebb és így kötelezően választandó eljárás a TAE-val szemben! [14] (Ugyanígy elmondható, hogy az endoscopos mucosa resectio, EMR technikáját mind "en block" arány, mind R0 arány és ezek alapján a lokális kiújulás (LR) arány vonatkozásában is felülmúlja az endoscopos submucosus dissectio (ESD) [15].…”
