2. Bleeding was the most common complication in gastric ulcer (38.9%), and perforation in duodenal ulcer (63.8%).
3. The Sex distribution assumed a ratio of 6.4 : 1, with 51 males and 8 females in gastric ulcer and 5.7: 1, with 40 males and 7 females in duodenal ulcer.
4. The peak of age incidence was 4th decade in both gastric and duodenal ulcer, but duodenal ulcer was more common than gastric ulcer in the age group below 3rd decade. except neonates, with a ratio of 1 : 3, but gastric ulcer was more common in the group over 6th decade, with a ratio of 2 : 1.
5. There was no significant difference in the seasonal distribution in both gastric and duodenal ulcer.
6. The duration of symptoms showed 2-5 years in the majority of both gastric and duodenal ulcer, and 23 cases(38.9%) of gastric ulcer and 22 cases(46.8%) of duodenal ulcer had not ulcer history.
7. Alcoholism is the most common disorder associated with both gastric and duodenal ulcer.
8. In blood group, B and 0 type(32.6% respectively) were the most common in gastric ulcer, and B type (31.5%) in duodenal ulcer.
9. There was no significant difference in gastric acidity between the gastric and duod￢enal ulcer.
10. The subdiaphragmatic free air was seen in the 94% of gastric perforation and 86.6% of the duodenal perforation.
11. In operative procedures except simple closure, subtotal gastrectomy was the most common procedure in gastric ulcer(82. 5%), but vagotomy with partial gastrectomy(such as antrectomy or hemigastrectomy), or with pyloroplasty(76.7%) in duodenal ulcer.12. Secondary operation after simple closure due to recurrent ulcer, was done in 3 cases (21. 4%) of gastric ulcer and 1 case(10.5%) of duodenal ulcer, this means more recurrence in gastric ulcer than duodenal ulcer, with a ratio of 3 : 1, after simple closure.
13. The postoperative complications were noted in 13 cases (22 %) of gastric ulcer and in 13 cases (27.6%) of duodenal ulcer and pulmonary complications such as atelectasis, effusion and pneumonia, and wound infection were common in both perforated ulcers.
14. The postoperative deaths were 6 cases (10.1%) in gastric ulcer and 1 case (2.1%) in duodenal ulcer and causes of deaths were septicemia(3). bleeding(1), hepatic coina(1), renal failure (1), heart failure (1).
