Impact of Olfactory Change on Postoperative Body Weight Loss in Patients with Gastric Cancer after Gastrectomy.

Patients undergoing gastrectomy for gastric cancer may experience alterations in olfaction, yet the association between olfactory changes and postoperative weight loss remains uncertain. This study aimed to elucidate the relationship between olfactory changes and postoperative weight loss in patients with gastric cancer. Patients who underwent radical gastrectomy for gastric cancer between February 2022 and August 2022 were included in the study.

Long-Term Insufficiency of Oral Intake after Esophagectomy: Who Needs Intense Nutritional Support after Esophagectomy?

Background: Patients with esophageal cancer are at a high risk of malnutrition after esophagectomy, and nutritional support may at times be required for several months following surgery. In this study, we aimed to clarify the clinical features and preoperative risk factors of patients with long-term insufficiency of oral intake after esophagectomy by evaluating the duration of feeding enterostomy placement.

Methods: A total of 306 patients who underwent esophagectomy, reconstruction with gastric conduit, and feeding enterostomy creation were retrospectively reviewed.
