Study Notes
Gastrointestinal Surgery Overview
- Involves management of diseases affecting the esophagus, stomach, small and large intestines, and rectum.
- Specializations include laparoscopic surgery, bariatric surgery, surgical oncology, and colorectal surgery.
Anatomical Components of the GI Tract
- Alimentary tract includes mouth, pharynx, esophagus, small intestine, large intestine, rectum, and anus.
- GI tract functions: ingestion, secretion, mixing and propulsion, digestion, absorption, and defecation.
Upper Gastrointestinal Tract Anatomy
- Esophagus: Approximately 25 cm long; transports food and fluids via peristalsis.
- Stomach: Contains fundus, body, and antrum; involved in food storage and digestion; absorbs vitamin B12.
- Small intestine: Approximately 3 meters long; consists of duodenum, jejunum, ileum; absorbs essential nutrients.
Isolation Bowel Technique
- Protects wound edges with extra drapes.
- Instruments used on bowel must be isolated after usage.
- Gowns, gloves, and drapes changed prior to closure.
Endoscopic Procedures
- Enables direct or video visualization of the GI tract.
- Involves local anesthetic and IV sedation with bowel prep.
- Requires high-level disinfection for scopes.
Surgical Procedures of the Esophagus and Stomach
- Esophageal cancer treatment via distal esophagectomy has high mortality; tumors typically found at late stages.
- Hiatus hernia involves stomach protruding into the thorax; classified into sliding and rolling types.
- Fundoplication repairs hiatus hernia and prevents reflux by plicating stomach tissue and performing crurorrhaphy.
- Laparoscopic Nissen fundoplication addresses GERD by wrapping the gastric fundus around the esophagus.
Types of Gastrectomy
- Partial Gastrectomy: Billroth I (stomach-duodenal anastomosis) and Billroth II (stomach-jejunal anastomosis).
- Total Gastrectomy: Complete stomach removal; uses esophageal-jejunal anastomosis.
- Gastric Bypass: Laparoscopic method for severe obesity; reduces stomach size and connects to jejunum.
Bowel Resection Techniques
- GIA stapler used for gastrointestinal anastomosis; staples and divides tissue simultaneously.
- Anastomosis types: end-to-end, side-to-side, end-to-side.
Surgical Procedures of the Small Bowel
- Common surgeries: appendectomy, small bowel resections, perforated duodenal ulcers, and ileostomy.
Surgery of the Colon & Rectum
- Includes right hemicolectomy, left hemicolectomy, transverse colectomy, low anterior bowel resection, abdomino-perineal resection, and colostomy creation or closure.
- Hartmann's procedure involves resection of the rectosigmoid colon with colostomy creation used in emergencies.
Specifics of Right Hemicolectomy
- Involves resection of the right half of the colon, including cecum, ascending colon, and part of the transverse colon; the ileum is anastomosed with the transverse colon.
Conclusion
- Gastrointestinal surgery encompasses a wide range of procedures varying from minimally invasive techniques to complex surgical interventions, focusing on restoring function and treating diseases of the GI tract.
