Acute Management of Mesoaxial Gastric Volvulus with Hiatal Hernia
Surgery is the definitive treatment for gastric volvulus associated with hiatal hernia, and in stable patients, a minimally invasive laparoscopic approach should be performed, consisting of gastric detorsion, reduction of herniated structures, hiatal hernia repair with cruroplasty, and gastropexy to prevent recurrence 1.
Initial Assessment and Stabilization
The acute management algorithm depends critically on hemodynamic stability and presence of gastric ischemia or perforation:
Unstable Patients (Septic Shock, Peritonitis, or Perforation)
- Immediate laparotomy is indicated without delay 1
- Perform damage control surgery if hemodynamically unstable with severe peritonitis 2
- Assess gastric viability intraoperatively—if necrosis is present, gastric resection is required 1
- Consider open abdomen approach in cases of extensive ischemia or persistent hemodynamic instability 2
Stable Patients
- Minimally invasive laparoscopic approach is preferred (mortality rate 0.14% vs. 17% morbidity with open approach) 1
- Initial nasogastric decompression may be attempted to stabilize the patient prior to surgery 3, 4
- Surgery should not be delayed beyond 12-24 hours even in stable patients with persistent symptoms 2
Surgical Technique
The operative approach for gastric volvulus with hiatal hernia involves four essential components:
Gastric Detorsion: Reduce the volvulus and assess viability 1
Reduction of Herniated Stomach: Pull the stomach back into the abdominal cavity from the thorax 3, 5
Hiatal Hernia Repair:
- Primary repair with non-absorbable sutures (cruroplasty) should be attempted first 1
- For defects >8 cm or >20 cm², mesh reinforcement is indicated 1
- Biosynthetic or biologic mesh can be safely used in clean-contaminated cases 1
- Mesh should overlap defect edges by 1.5-2.5 cm 1
- Avoid tackers near the pericardium due to risk of cardiac complications 1
Gastropexy: Essential to prevent re-torsion 1, 5, 6
- Anterior gastropexy is the most commonly performed technique 5
Fundoplication Considerations
Fundoplication should be performed selectively based on:
- History of gastroesophageal reflux 1
- Large defect requiring repair 1
- Paraesophageal hernia component 1
Both Nissen and Toupet fundoplication are effective, though some evidence suggests lower recurrence rates with Toupet 1, 5. Recent successful cases have utilized Toupet fundoplication with good outcomes 5.
Critical Pitfalls to Avoid
Delayed surgical intervention: Mortality increases significantly with delays beyond 24 hours, particularly if ischemia develops 7, 4
Inadequate assessment of gastric viability: Ischemic changes may not be immediately apparent—careful inspection is mandatory 4, 6
Failure to perform gastropexy: This is the most common cause of recurrent volvulus 1, 6
Use of absorbable sutures: Only non-absorbable sutures should be used for hiatal repair to prevent recurrence 1
Inadequate mesh overlap: When mesh is required, ensure 1.5-2.5 cm overlap to prevent recurrence 1
Special Considerations
In elderly or high-risk surgical candidates: While endoscopic decompression alone is insufficient for definitive treatment, it may serve as a temporizing measure in extremely high-risk patients 6. However, this should not substitute for definitive surgical repair, as recurrence and complications are inevitable without anatomical correction 6.
Postoperative monitoring: Watch for complications including pulmonary atelectasis (most common), surgical site infection, respiratory failure, and gastroesophageal reflux 1. Laparoscopic approach significantly reduces morbidity (5-6%) compared to open surgery (17-18%) 1.
The laparoscopic approach offers excellent safety profile with reported in-hospital mortality of 0.14%, faster recovery, and reduced postoperative complications 1, 3, 4, 5, 6.
