Operation performed for obesity also involve removal of part of the stomach.
Following is list of types of stomach surgery performed by gastrosurgeon:
  • Partial Gastrectomy – Part of stomach is removed (Also called distal gastrectomy or subtotal gastrectomy)
  • Total Gastrectomy – Entire stomach is removed
  • Gastrojejunostomy – Part of stomach is joined with small intestine (Stomach not removed)
  • Sleeve gastrectomy – A sleeve of stomach is removed for obesity surgery
  • RYGB or gastric bypass – Large part of stomach is removed & remaining part is joined with small intestine

Stomach surgery is usually performed by gastrosurgeon, who specializes in this field, also called GI Surgeon.

Immediately after the operation, the patient is shifted to recovery ward or an ICU. Patient will not be allowed to take orally from 1 to several days, depending upon the judgement of gastrosurgeon.
