Partial resection of the stomach recovers well. Total gastrectomy is mostly used for gastric cancer surgery in clinic. Total gastrectomy is more traumatic, the storage function of stomach disappears, and the postoperative recovery time is longer, plus the lack of stomach can cause a series of clinical symptoms, such as dyspepsia, anemia, malnutrition, and lack of microbial elements, etc., so the recovery is poorer than that of partial gastrectomy. Partial gastrectomy is clinically used for the treatment of smaller stomach cancer or other stomach diseases. Since the operation is less traumatic than total gastrectomy and part of the stomach tissue and function are preserved, it is better than total gastrectomy in terms of food storage and nutrient absorption, and the complications such as malnutrition, anemia, indigestion, etc. are relatively less serious. In general, partial gastrectomy has a better recovery than total gastrectomy.
