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...

Inflammatory Bowel Disease V: Surgical Management

Surgical interventions for inflammatory bowel disease (IBD), which includes ulcerative colitis and Crohn's disease, are essential in managing symptoms and addressing complications. The selection of surgical procedures is contingent upon the specific conditions and complications that stem from these illnesses.
Here are some common surgical interventions for IBD:

Area of Science:

Colorectal Surgery
Minimally Invasive Surgery
Surgical Oncology

Background:

Transanal minimally invasive surgery (TAMIS) emerged in 2010, combining elements of single-incision laparoscopic surgery and transanal endoscopic microsurgery (TEM).
It provides access to the proximal and mid-rectum for resecting benign and early-stage malignant rectal lesions.
TAMIS is also applicable for noncurative surgery in patients unsuitable for radical procedures.

Purpose of the Study:

To evaluate the applications and feasibility of Transanal minimally invasive surgery (TAMIS).
To highlight TAMIS as an alternative to transanal endoscopic microsurgery (TEM).

Main Methods:

Utilizes readily available operating suite equipment and a specialized TAMIS port.
Technique involves minimally invasive access to the rectum for lesion resection.

Main Results:

TAMIS demonstrates broad utility beyond local excision, including fistula repair, foreign body removal, hemorrhage control, and as an adjunct in total mesorectal excision.
The procedure is technically feasible and cost-effective.

Conclusions:

Transanal minimally invasive surgery (TAMIS) is an accessible, feasible, and cost-effective surgical option.
It serves as a valuable alternative to transanal endoscopic microsurgery (TEM) for various rectal conditions.
