    Abstract:
    BACKGROUND/AIMS: We evaluated the quality of life and gastric emptying in patients who had undergone a segmental gastrectomy to treat early gastric cancer in the middle part of the stomach. METHODOLOGY: Thirty patients were considered in this study. Their mean age was 65.5 years (range: 44-83). All of the patients were free from recurrence of their cancer in the follow-up period. This ranged from 5 to 50 months (mean 30). Patients were interviewed at regular intervals to assess their quality of life and to note particular complaints. The upper gastrointestinal tract was assessed endoscopically. A gastric emptying study was performed at 3, 6, and 12 months after surgery. The meal used in this dual-phase study had solid and liquid phases. For the solid phase, 74 MBq of 99mTc sulfur colloid was injected into an egg, which was then hard-boiled. For the liquid phase, 18.5 MBq of (111)In-diethyltriaminopenta acetic acid (DTPA) were mixed into 150 ml of a commercial, elentary liquid diet. RESULTS: Three months after surgery, the patients' main complaints were gastric stasis (25%), heartburn (8%) and belching (8%). The patients gradually became asymptomatic following surgery. Fifty-nine percent were asymptomatic at the 3-month follow-up, 84% at 6 months, and 92% at 12 months. There was no evidence of reflux esophagitis or gastritis after the 3-month follow-up. One patient developed a complicated duodenal ulcer. Initially, the patients all had prolonged gastric emptying of the dual phase meal, compared to normal individuals. The T1/2 for liquid meal emptying was 87+/-18 min at 3 months, 77+/-20 min at 6 months and 50+/-5 min at 1 year after surgery. The last value is the same as for healthy individuals. Solid meal emptying was still prolonged, with an emptying rate of 36+/-9.7% at 2 hours, one year after surgery. CONCLUSIONS: Segmental gastrectomy patients experienced prolonged gastric emptying in the early post-operative period. This improved in the first year after surgery. The quality of life for patients who underwent segmental gastrectomy has been reasonably good in the follow-up period to date.
