Study Notes
Gastrointestinal Surgery Overview
- Subspecialty of general surgery focusing on diseases of the esophagus, stomach, small intestine, large intestine, and rectum.
- Includes specializations like laparoscopic surgery, bariatric surgery, surgical oncology, and colorectal surgery.
Anatomical Components
- GI tract is a tubelike structure extending throughout the trunk comprising the alimentary tract: mouth, pharynx, esophagus, small intestine, large intestine, rectum, and anus.
- Basic functions encompass ingestion, secretion, mixing, propulsion, digestion, absorption, and defecation.
Surgical Anatomy: Upper GI Tract
- Esophagus: 25 cm long, connects pharynx to stomach, responsible for peristalsis in food/fluid transport.
- Stomach Structure: Divided into fundus, body, and antrum; stores food and fluid; performs chemical and mechanical digestion; absorbs vitamin B12.
- Small Intestine: 3 meters long (duodenum, jejunum, ileum); primary site for nutrient absorption and protective barrier.
Isolation Bowel Technique
- Protects wound edges with drapes; isolates instruments used on bowel; requires changing gowns and gloves before closure to reduce infection risk.
Gastrointestinal Endoscopy
- Utilizes direct or video visualization for diagnosis and intervention; requires bowel preparation and high-level disinfection for scopes; utilizes local anesthetic and IV moderate sedation.
Diseases of the Esophagus
- Distal Esophagectomy: Treatment for esophageal cancer, typically diagnosed at late stages resulting in high mortality.
- Hiatus Hernia: Protrusion of stomach into thorax; can be sliding or rolling; associated with GERD (gastroesophageal reflux disease) and Barrett's esophagus.
- Surgical Fix: Fundoplication procedure combining tissue folding to shorten stomach and permanent suture repair (crurorrhaphy).
Laparoscopic Nissen Fundoplication
- Management for GERD; gastric fundus is wrapped around lower esophagus to reinforce the lower esophageal sphincter; requires a lithotomy position and specific surgical instruments.
Surgery of the Stomach
- Types of surgery include partial gastrectomy (Billroth I and II) and total gastrectomy.
- Total gastrectomy involves full stomach removal, with an esophageal-jejunal anastomosis.
- Billroth I involves pyloric resection; Billroth II links stomach to jejunum.
Surgery of the Small and Large Bowel
- Common procedures include appendectomy, small bowel resections, right hemicolectomy, left hemicolectomy, and colostomy creation.
- Right Hemicolectomy: Resection includes cecum, ascending, part of transverse colon; anastomosis between ileum and transverse colon.
Hartmann's Procedure
- Surgical resection of the rectosigmoid colon, closure of the rectal stump with colostomy; typically performed in emergencies like bowel obstruction or perforation.
Low Anterior Bowel Resection
- Typically indicated for diverticulitis and cancer; requires protection of ureters and end-to-end anastomosis.
Abdominoperineal Resection
- Resection of lower sigmoid colon, rectum, and anus; performed through both abdominal and perineal incisions; involves permanent colostomy; requires two surgical teams.
Atraumatic Instruments
- Essential for minimizing tissue damage during procedures; includes various retractors, scissors, and specialized tools.
Summary
- GI surgery encompasses a variety of procedures that can be adapted for minimally invasive approaches.
- A strong understanding of surgical anatomy is crucial for effective surgical planning and care for GI patients.
