Study Notes
Digestive Secretions and Intestinal Obstruction
- Intestinal obstruction can lead to hypersecretion of digestive fluids and air, causing peritonitis in cases of bowel perforation.
- Presence of peritonitis influences the severity and management of bowel obstruction.
- History of multiple operations increases the risk of adhesion, which contributes to post-operative complications.
Local and Systemic Consequences
- Severity of local and systemic damage correlates with the duration and degree of obstruction, along with ischemia.
- Ischemia exacerbates damage, highlighting the urgency of treatment for prolonged obstructions.
Neoplasia
- Neoplasia is responsible for about 20% of small bowel obstructions.
- Colorectal and ovarian metastases are common causes, primarily due to the health of the bowel mucosa being critical for prevention of obstruction.
Clinical Manifestations
- Presence of a tender mass in the inguinal, femoral, or umbilical regions indicates possible obstruction.
- Proximal small bowel obstruction may show minimal abdominal distention but can involve significant vomiting.
- Closed-loop small bowel obstruction is characterized by pain disproportionate to physical findings.
Laboratory Findings
- Laboratory tests, such as CBC, may reveal leukocytosis and hemoconcentration indicating fluid losses.
- Significant neutrophilia in WBC counts suggests possible strangulation requiring urgent surgical intervention.
- Renal function tests may show elevated BUN and creatinine levels due to dehydration.
Surgical Management
- Urgent surgical management is necessary in cases of small bowel strangulation.
- Delayed treatment can lead to bowel gangrene, necessitating resection of non-viable intestine.
Recurrence and Outcomes
- High rate of recurrence (up to 70% within 1 year, 85% in 3 years) post-surgical management of adhesive small obstructions.
- Patients often present again with symptoms such as pain, diarrhea, and fever.
Diagnostic Imaging and Procedures
- Plain abdominal X-rays and CT scans are vital for confirming the diagnosis.
- Balloon enteroscopy allows visualization of the jejunum and can reveal GISTs causing gastrointestinal bleeding.
- Endoscopic procedures like EGD and colonoscopy facilitate biopsy and diagnosis of upper and terminal ileum tumors respectively.
- Capsule endoscopy enables detailed visualization of the small intestine by capturing images while the capsule traverses the GI tract.
Complications of Obstruction
- Common complications include wound infections, intra-abdominal abscesses, and anastomotic leaks, which present significant challenges during postoperative management.
- Without treatment, patients face lifelong complications from small bowel obstruction, necessitating careful monitoring and management.
