Surgical Management of Abdominal Conditions
Initial Assessment and Treatment
- The World Journal of Emergency Surgery guidelines recommend endoscopic assessment first in stable patients, allowing direct visualization of the gastric pouch, stoma, and proximal portions to identify complications 1
- CT scan is the diagnostic test of choice to identify intussusception, particularly in patients who have undergone bariatric surgery 1
- Diagnostic workup for small intestine obstructions and complications should include laboratory tests such as white blood cell count and C-reactive protein to assess for infection/inflammation, as recommended by the World Journal of Emergency Surgery guidelines 2
- Nasogastric tube placement can provide immediate gastric decompression while preparing for endoscopy, according to the World Journal of Emergency Surgery guidelines (2022) 1
Diagnostic and Therapeutic Interventions
- Endoscopic balloon dilation has a success rate of 88-94% for treating strictures, and endoscopic fragmentation and removal can be used to treat food impaction or bezoar, as recommended by the World Journal of Emergency Surgery guidelines (2022) 1
- Decompression via colonoscopy or stenting can be used as a bridge to surgery in select cases of Large Bowel Obstruction 3
- Endoscopic evaluation is recommended for patients with gastric bypass changes and apparent thickening of the gastric pouch, to directly visualize the gastric pouch, stoma, and proximal Roux limb and assess for potential complications such as marginal ulcers, stenosis, and gastro-gastric fistula 1
- Bezoar can be managed with an endoscopic approach for gastric bezoars and surgical intervention for small bowel bezoars 1
Surgical Indications and Approaches
- Immediate surgical exploration is recommended in unstable patients presenting with peritonitis 1
- Surgical intervention is indicated for failed conservative management, signs of strangulation/ischemia, complete obstruction, or fibrotic or medically-resistant stenosis 4
- Laparoscopic approach is recommended for adhesiolysis and bowel resection if expertise exists 4
- Surgical resection is recommended for malignant obstruction, with Hartmann procedure preferred over anastomosis in unstable patients 3
- Laparoscopic primary repair with omental patch is recommended in stable patients with gastroduodenal perforation 1
- Open approach is preferred for large bowel perforation, and avoid colorectal anastomosis in high-risk patients due to increased complication risk 3
Non-Operative Management
- Non-operative management (NOM) with antibiotics is a valid first-line option for uncomplicated appendicitis, with benefits including lower overall complication rate and shorter sick leave compared to surgery 5
- Conservative management for adhesive Small Bowel Obstruction (SBO) includes nasogastric decompression, IV fluids, and electrolyte correction 3
- Medical therapy, including high-dose proton pump inhibitors, is the first-line treatment for gastric bypass changes, with regular endoscopic follow-up to monitor healing 1
- Appendiceal abscess can be managed with percutaneous drainage + IV antibiotics if technically feasible 3, 5
Post-Surgical Care
- Early mobilization is recommended to prevent complications in post-surgical patients, as suggested by the American College of Obstetricians and Gynecologists and the American Journal of Obstetrics and Gynecology 6
- Administer appropriate antibiotics for 4-7 days based on clinical condition, with recommended regimens including Piperacillin/tazobactam 4g/0.5g q6h or 16g/2g by continuous infusion, or Eravacycline 1 mg/kg q12h for patients with beta-lactam allergy 7
- Monitoring for complications such as anastomotic leak, recurrent fistula, wound infection, and short bowel syndrome is crucial in post-surgical patients, as supported by the World Journal of Emergency Surgery guidelines 8, 1
- Regular assessment of nutritional status and supplementation if needed is recommended for post-surgical patients, as suggested by the American College of Obstetricians and Gynecologists and Clinical Nutrition 6, 9
Emergency Situations
- Immediate surgical exploration is mandatory for life-threatening conditions such as acute appendicitis, intestinal obstruction, and perforated viscus, while non-operative management can be considered for select uncomplicated cases to reduce morbidity and mortality 3, 5
- Initial assessment by a senior clinician is crucial to promptly recognize surgical necessity 3
- Delay in surgical intervention beyond 48 hours is associated with significantly increased mortality, emphasizing the importance of prompt diagnosis and treatment 1
- Surgical decisions should be shared with the anesthesia team given potential resource limitations 3
- All acute patients should be considered COVID-19 suspected cases until proven otherwise 3
- Damage control surgery should be considered in hemodynamically unstable patients with extensive contamination 4
