Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.
Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...

Area of Science:

Colorectal Surgery
Surgical Oncology
Minimally Invasive Procedures

Background:

Transanal minimally invasive surgery (TAMIS) represents a new technique for rectal lesion removal.
Initial clinical experience with TAMIS is reviewed to assess its feasibility and outcomes.

Purpose of the Study:

To evaluate the initial experience and outcomes of Transanal Minimally Invasive Surgery (TAMIS) for rectal lesion resection.

Main Methods:

A review of clinical data from patients undergoing TAMIS between March and May 2012.
Data collected included patient demographics, tumor characteristics, surgical technique, histology, and post-operative results.

Main Results:

Three patients underwent successful TAMIS resection of rectal tumors (tubulovillous adenomas with high-grade dysplasia, one with adenocarcinoma).
Complete tumor resection with clear margins was achieved in all cases.
One patient experienced a post-operative bleed requiring reoperation.

Conclusions:

Transanal minimally invasive surgery (TAMIS) is a viable and cost-effective alternative to transanal endoscopic microsurgery for rectal lesions.
TAMIS may offer a reduced learning curve, particularly for surgeons experienced in single-port laparoscopic techniques.
