Summary
The X-Tack through-the-scope suturing (TTSS) system effectively closes small complex gastrointestinal defects (CGDs). This minimally invasive technique achieved high success rates, even in challenging locations.
Area of Science:
- Gastroenterology
- Minimally Invasive Surgery
- Endoscopy
Background:
- Management of complex gastrointestinal defects (CGDs) like fistulas and leaks is challenging.
- Existing over-the-scope suturing (OTSS) systems have anatomical limitations.
- Through-the-scope suturing (TTSS) offers a less invasive alternative for CGD closure.
Purpose of the Study:
- To evaluate the safety and efficacy of the X-Tack TTSS system for closing small CGDs (≤25 mm).
- To assess the technical success and clinical outcomes of TTSS in various anatomical locations.
Main Methods:
- A case series of thirteen patients undergoing TTSS closure for CGDs ≤25 mm.
- Pre-procedural assessment included CT scans and multidisciplinary board review.
- X-Tack system used in figure-of-8 or zig-zag patterns; follow-up included clinical and lab assessments.
Main Results:
- 100% technical success rate for TTSS closure.
- 76.9% achieved clinical and laboratory remission at seven days.
- Sustained clinical remission in 76.9% after a median follow-up of 2.5 months.
- Effective in challenging sites like post-surgical anastomotic leaks and narrow lumens.
Conclusions:
- TTSS using the X-Tack system is a safe and effective method for closing small CGDs.
- The system demonstrates efficacy in difficult-to-reach anatomical locations.
- TTSS represents a valuable minimally invasive option for managing specific complex gastrointestinal defects.

Endoscopic Procedures III: Video Capsule Endoscopy
678
Capsule endoscopy, or wireless or video capsule endoscopy, is a diagnostic procedure for examining the entire gastrointestinal tract. Patients swallow a capsule about the size of a vitamin tablet. The capsule is equipped with a transmitter, a battery, an LED light source, and a color video camera to capture images throughout the gastrointestinal tract. This procedure is particularly useful for diagnosing conditions such as Crohn's disease, ulcerative colitis, tumors, polyps, ulcers,...

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy
526
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.

Inflammatory Bowel Disease V: Surgical Management
429
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:

Endoscopic Procedures I: Esophagogastroduodenoscopy
841
An Esophagogastroduodenoscopy (EGD) is a diagnostic procedure in which an endoscopist uses a flexible, lighted endoscope to visualize the upper gastrointestinal (GI) tract. The procedure includes visualizing the oropharynx, esophagus, stomach, and the first part of the small intestine, the duodenum.
During an EGD, the endoscope can be used to:

Endoscopic Procedures II: Colonoscopy
579
The colon, or large intestine, is the final segment of the digestive system. Its primary functions include absorbing water and vitamins produced by gut bacteria and transforming waste from liquid to solid to form stool. In adults, the large intestine is approximately 5 feet long and consists of four main sections:
