ASGE Annual GI Advanced Practice Provider Course (Virtual) (Day One) | March 2026-Bariatric and Endoluminal Interventions What APPs Should Know

Pdf Summary

This presentation reviews bariatric and endoluminal (endoscopic) weight-loss interventions and practical “red flags” for advanced practice providers. It highlights a major treatment gap in obesity care: while obesity is prevalent, many patients do not want surgery and only about 1% of eligible patients undergo bariatric surgery. The “modern metabolic toolbox” is positioned as a continuum from lifestyle therapy and anti-obesity medications to surgery, with endoluminal options helping bridge the gap.<br /><br />Key bariatric surgery considerations include expected total body weight loss (roughly 30–45% depending on procedure) and urgent post-op warning signs: tachycardia may signal an anastomotic leak (and can be masked by beta blockers), epigastric pain radiating to the back may indicate an internal hernia (a surgical emergency; CT “swirl sign,” labs may be normal), and persistent vomiting may reflect an anastomotic stricture with risk of thiamine deficiency/Wernicke’s encephalopathy. Lifelong nutritional monitoring is emphasized (baseline, 3, 6, 12 months, then annually), including bone health, anemia, “transfer addiction,” and bariatric multivitamins.<br /><br />Endoluminal therapies discussed are intragastric balloon (IGB) and endoscopic sleeve gastroplasty (ESG). IGB is indicated for BMI 30–40 after failed lifestyle therapy; it is fully reversible and produces ~10–15% TBWL over 6 months but requires PPI use and a second endoscopy for removal, with risks such as ulcer/bleeding, perforation, migration, hyperinflation, pancreatitis, and intolerance. ESG is FDA-approved for BMI 30–50, has a low risk profile and ~1 week recovery, is semi-permanent, and typically yields 13–20% TBWL at 12 months; contraindications include cirrhosis, esophageal stricture, large hiatal hernia, need for gastric surveillance, Crohn’s disease, and severe cardiopulmonary disease. Endobariatric red flags include tachycardia/fever/left shoulder pain (leak), tachycardia with melena (upper GI bleed), dehydration/constipation, and early hunger/weight regain (suture failure). A staged post-procedure diet progression is provided.<br /><br />The talk also stresses lifestyle fundamentals (high-protein, lower-carb; fiber for maintenance; protein targets ~1.2–1.5 g/kg lean body weight) and exercise to prevent sarcopenia (150–300 minutes/week plus resistance training). A case illustrates that symptoms may have unrelated causes (large benign mucinous cystadenoma found months after ESG). The conclusion summarizes indications: surgery for BMI ≥40 or ≥35 with severe comorbidities; endoluminal options for BMI 30–50; lifestyle changes for all.
