Study Notes
Learning Objectives
- Identify components of the gastrointestinal (GI) tract and their functions.
- Explain considerations and types of procedures in GI surgery.
- Differentiate instrumentation for GI procedures.
- Understand Isolation Bowel Technique for reducing contamination.
- Distinguish between upper and lower GI endoscopic procedures.
- Compare surgical staplers and their applications in various surgeries.
Overview of GI Surgery
- Subspecialty within general surgery focusing on the esophagus, stomach, small and large intestines, and rectum.
- Specializations include laparoscopic, bariatric, surgical oncology, and colorectal surgery.
Surgical Anatomy
- GI tract is a continuous tubelike structure extending throughout the trunk.
- Alimentary tract includes the mouth, pharynx, esophagus, small intestine, large intestine, rectum, and anus.
- Basic GI functions: ingestion, secretion, mixing and propulsion, digestion, absorption, and defecation.
Upper GI Tract
-
Esophagus:
- Length of 25 cm (10 inches).
- Responsible for transporting food and fluids via peristalsis.
-
Stomach:
- Comprised of fundus, body, and antrum.
- Functions include accepting/storing food, chemical mechanics, and vitamin B12 absorption.
-
Small Intestine:
- 3 meters long, consisting of duodenum, jejunum, and ileum.
- Absorbs essential nutrients and provides a protective barrier.
Lower GI Tract
-
Large Intestine:
- Composed of ascending, transverse, descending colon, sigmoid colon, rectum, and anus.
- Responsible for water/electrolyte reabsorption and solid waste formation.
- Synthesizes vitamin K and B vitamins.
Mesenteric Arteries
- Superior Mesenteric Artery (SMA): Supplies most of the small intestine and ascending colon.
- Inferior Mesenteric Artery (IMA): Supplies transverse colon (splenic flexure) down to the rectum.
Surgical Techniques and Considerations
-
Isolation (Bowel) Technique:
- Wound edges protected with drapes; instruments are isolated post-use until closure.
- Gloves and gowns changed before closure for contamination control.
-
GI Instrumentation:
- Basic sets used in laparotomy/laparoscopy include retractors, clamps, suction, and staples.
- Instruments used follow the sequence: Clamp, Clamp, Cut, Tie.
Endoscopic Procedures
- Enable direct or video visualization of the GI tract.
- Utilize local anesthetics with IV sedation.
- Require bowel preparation and high-level disinfection for scopes.
Common GI Surgeries
-
Esophagus:
- Distal esophagectomy has a high mortality rate due to late-stage tumor discovery.
- Hiatus hernia (sliding and rolling types) can lead to gastroesophageal reflux disease (GERD).
- Fundoplication repair technique involves plication and crurorrhaphy to prevent reflux.
-
Stomach:
- Partial gastrectomy (Billroth I and II) and total gastrectomy.
- Total gastrectomy involves esophageal-jejunal anastomosis for curative or palliative treatment.
-
Colectomy:
- Sigmoid colectomy (low anterior resection) and abdominoperineal resections involve specific patient positioning and careful management of surgical instruments.
Minor Surgeries
- Excision of pilonidal cysts involves primary or secondary closure methodologies.
Summary
- GI surgery encompasses treatments for a wide range of conditions affecting the esophagus, stomach, and intestines, with advances toward minimally invasive approaches being prominent.
- Comprehensive understanding of surgical anatomy is crucial for effective surgical care and management.
