Abstract:
A Radical gastrectomy can affect the dumping syndrome, reflux gastritis, injury of the autonomic nervous system and the small capacity syndrome and can cause some problems in the quality of life for post-gastrectomy patients. To minimize these complications in the treatment of early gastric cancer (EGC), various gastric-reduced operations have been discussed by gastric surgeons. A pylorus preserving gastrectomy (PPG) is a kind of reduced-gastric operation which preserves the distal portion (1.5 cm) of the gastric antrum and reduces postoperative complications such as the dumping syndrome and reflux esophagitis. However, a limitation of this operation is that complete lymph node dissection of the suprapyloric lymph node is undesirable for preservation of the pyloric branch of the vagus nerve. Nowadays, some reports state that this operation may be applicable in EGC confined to the mucosa and located at the gastric mid-body. (Purpose) This study was designed to evaluate the gastric function after PPG by using solid foods to obtain the gastric emptying time. (Materials and Method) From June 1995 to December 1995, we performed PPGs on 7 patients (4 patients with mucosal cancer, 2 patients with gastric ulcer and 1 patient with a leiomyoma) and Billroth I reconstruction in 7 patients (5 patients with mucosal cancer, 1 patient with advanced gastric cancer and 1 patient with gastric ulcer). To compare the gastric function between these two subgroups, we analyzed the lag time, T1/2 and the residual food after 100 min using 99mTc-tin-colloid-steamed eggs to obtain the gastric emptying time for the PPG group (n=7), the Billroth I reconstruction group (n=7), and the normal control group (n=7). A statistical analysis was done by using the Kruskal-Wallis test (Chi-square approximation). (Results) There were no differences in the amount of transfusion, the hospital stay, the operation time, and the body weight loss after operation between the PPG group and the Billroth I reconstruction group. The severe dumping syndrome and reflux esophagitis were found in one of the patients after Billroth I reconstruction, but were not found in PPG group. Statistically, there was no difference in T1/2 between the Billroth I reconstruction group and the PPG group; however, both lag times were longer than that of the normal control group. We also found that the residual food 100 min after oral intake was greater in both the Billroth I reconstruction and the PPG groups than in the normal control group. (Conclusion) Though both PPG and Billroth I reconstruction showed delayed gastric emptying, we found that PPG is superior to Billroth I reconstruction in lag time and in the amount of residual food after 100 min. We conclude that PPG is superior to Billroth I reconstruction in gastric motility, and if this operation is applied in indicated gastric cancer patients, post-operative complications, such as the dumping syndrome and reflux esophagitis can be reduced and the quality of life in post-gastrectomy patients can be increased.
