Stomach Surgery Specialists: Who Performs Gastric Procedures?

Stomach surgeries are primarily performed by gastrointestinal surgeons—a subspecialty of general surgery—or bariatric surgeons (for weight-loss procedures). It's important to distinguish these surgeons from gastroenterologists.

Clarifying the Specialists

• Gastroenterologists are internists who diagnose and treat GI diseases medically and perform endoscopy (EGD, colonoscopy, ERCP, EUS). They do not perform surgery.
• General surgeons perform common gastric surgeries: gastrectomy (cancer, severe ulcer), perforation repair, anti-reflux procedures (fundoplication).
• Surgical oncologists handle complex gastric cancer resections with extended lymphadenectomy (D2).
• Bariatric surgeons specialize in metabolic/bariatric procedures: gastric bypass, sleeve gastrectomy, adjustable gastric banding, revisions.
• Foregut/Upper GI surgeons focus on esophageal and gastric disorders: achalasia, GERD, paraesophageal hernia, gastroparesis.

Common Gastric Surgeries

• Partial or total gastrectomy (cancer, severe ulcer disease)
• Roux-en-Y gastric bypass (RYGB)
• Sleeve gastrectomy
• Fundoplication (Nissen, Toupet) for GERD
• Gastric pacing, per-oral endoscopic myotomy (POEM) for achalasia

Choosing a Surgeon

For any stomach surgery, seek a surgeon with:

• Board certification in general surgery
• Fellowship training in minimally invasive, bariatric, foregut, or surgical oncology (as relevant)
• High procedural volume in the specific operation you need
• Good outcomes data (mortality, complication, reoperation rates)

The right specialist makes a measurable difference in outcomes. Don't hesitate to ask about training, volume, and results.
