Study Notes
Operating Room Considerations
- An OR table must support excessive weight during bariatric surgeries to ensure patient safety.
- Bowel/isolation technique is crucial to prevent cross-contamination and mechanical metastasis during GI surgeries.
Bowel Isolation Technique
- Initiated once the GI tract is clamped, focusing on irrigation before wound closure.
- Bowel instruments are kept separate from clean instruments; often passed off to the circulating nurse with the specimen.
- Extra draping around the incisional area is recommended, with surgical team changing gloves post-anastomosis completion.
Stapling Devices Overview
- GIA Stapler: Disposable, reloadable, cuts and staples, used for side-to-side anastomoses.
- TA Stapler: Disposable, reloadable, staples tissues together with manual cutting required.
- EEA Stapler: Disposable, not reloadable, cuts and staples for end-to-end or end-to-side anastomoses, often used to reduce colostomy needs.
Types of Anastomoses
- End-to-End: Directly connects two bowel segments.
- Side-to-Side (Functional End-to-End): Connects two segments after resection, allows for different lumen sizes, and functions like end-to-end after healing.
- End-to-Side (Roux-en-Y): Joins one segment to the side of another, often for reconstructive purposes.
Mesenteric Repair
- After bowel resection, it's critical to repair corresponding mesenteries to maintain blood supply from Superior and Inferior mesenteric arteries, preventing bowel entrapment and obstruction.
Procedures in GERD Management
- Nissen Fundoplication: Addresses mechanical dysfunction of the lower esophageal sphincter; can be performed open or laparoscopically, forming a wrap around the lower esophagus.
Bariatric Surgical Procedures
- Sleeve Gastrectomy: Removes 85% or more of the stomach to restrict food intake.
- Adjustable Laparoscopic Band: Constricts the upper stomach, limiting food intake.
Colorectal Cancer Insights
- Commonly occurs in the rectosigmoid area, particularly in those over 50. Early detection of polyps can lead to successful treatment.
Surgical Interventions for Colorectal Cancer
- Right Hemicolectomy, Left Hemicolectomy, Transverse Colectomy, Anterior Resection, Sigmoid Colectomy, Abdominal Perineal Resection: Different approaches depending on cancer location and extent.
Colostomy/Ileostomy Creation
- Temporary Colostomy: Allows bowel rest or anastomosis healing, often in emergency situations.
- Permanent Colostomy: Required in cases like Abdominoperineal resection for rectal tumors.
Closure Techniques
- Hartmann Colostomy: A colostomy done when a primary anastomosis isn't feasible; involves bringing out the proximal bowel to the skin while closing the distal stump.
Advanced Procedures
- Ileal Anal Pull Through: Suitable for ulcerative colitis; removes the large bowel and part of the rectum, creating a pouch from the small bowel attached to the anus, maintaining sphincter control.

Description
This quiz covers essential procedural considerations for bariatric and gastrointestinal surgeries, focusing on the importance of using specialized operating room tables for patient safety. Additionally, it addresses the bowel/isolation technique, which is vital in preventing cross-contamination during surgeries, especially cancer procedures.
