A Roux-en-Y gastric bypass is a procedural variant for gastric partitioning for morbid obesity to reduce food intake where the stomach is partitioned into a proximal and distal pouch (<50mL) with an anastomosis to the jejunum to drain the proximal pouch[1]. Food then bypasses over 95% of the stomach, duodenum, and jejunum. Many patients who have Roux-en-Y gastric bypass lose more than 25% of weight after 1 year[2]. Patients who had Roux-en-Y gastric bypass experienced higher remission and lower rates of hypertension, diabetes, and hyperlipidemia[3].
Preoperative management
Patient evaluation
| System | Considerations |
|---|---|
| Neurologic | |
| Cardiovascular | Evaluate for hypertension
OSA causing pulmonary arterial hypertension |
| Pulmonary | Evaluate BMI for decreased FRC
Evaluate OSA status for difficult mask ventilation |
| Gastrointestinal | Consider delayed gastric emptying with diabetes mellitus |
| Hematologic | |
| Renal | |
| Endocrine | Consider delayed gastric emptying with diabetes mellitus |
| Other |
Labs and studies
- Sleep study (AHI score if available) for OSA
Operating room setup
- Consider ramp for airway management
- Consider video laryngoscopy
- OG tube
- Methylene Blue and 60mL syringe
Patient preparation and premedication
- Minimize perioperative sedation
Regional and neuraxial techniques
- Consider post-operative TAP block
Intraoperative management
Monitoring and access
- Standard ASA monitors
Induction and airway management
- Consider rapid sequence induction
- Video laryngoscopy can be helpful for anticipated difficult airways
Positioning
- Supine
- Extreme reverse Trendelenburg (place baseboard by feet)
Maintenance and surgical considerations
- OG tube is advanced through the surgical anastomosis to prevent backwall suturing of anastomosis
- Surgical and anesthesia communication and coordination is important to guide OGT through anastomosis
- Methylene blue 60mL used at the end of the case to pressurize the proximal pouch and look for leaks across the staple line of the anastomosis.
Emergence
Postoperative management
Disposition
- PACU
Pain management
- Moderate pain: IV and oral narcotics
Potential complications
- Bleeding
- Thromboembolic events
- Aspiration
- Backwall suture of anastomosis
- Mortality is 0.2-0.3% with a laparoscopic approach[4]
- 25% of patients require revision of their procedures after 10 years of follow-up[5]
