Surgical treatment of peptic ulcer disease: Changing patterns in the past 40 years

During the past 40 years (1951-1990), 7,663 patients with peptic ulcer disease underwent surgical treatment at the National Taiwan University Hospital. A gr-eat change in patient characteristics and operative procedures was noted between the last 10 years and the previous three decades. There were 7,105 patients (92.7%) between 1951 and 1980, an average of 237 patients per year. However, only 558 patients received surgery in the last 10 years, an average of 56 patients per 7 ear. The proportion of female patients increased from 9.5% in the earlier period to 29.4% in the last 10 years; the average age of patients also increased. In the earlier period, the indications for surgery were hemorrhage (38.4%), perforation (36.1%), intractable pain (16.4%) and stenosis (9.1%). Perforation (89.2%) was the most common indication for surgical treatment in the last 10 years. Hemorrhage (4.9%), pain (4.1%) and stenosis (1.8%) were less common. There was no significant difference in surgical morbidity between the two periods. Primary subtotal gastrectomy (SG) accounted for 75.4% of operations in the earlier period, but vagotomy became the main treatment in the last 10 years, including highly selective vagotomy (HSV) (31.9%), and truncal vagotomy with drainage procedure (TV + D) (31.0%). The surgical mortality in the earlier period was 1.3% for SG, 1.8% for TV + D and 16.1% for simple closure. There was no significant change in ulcer location between the two periods. The overall mortality rate was higher in the last 10 years (5.2%) than in the earlier 30 years (2.7%) (p < 0.001). In follow-up studies, the satisfactory rate after operation was similar among patients receiving SG (89.8%), HSV (90.3%) and TV + D (91.1%) between 1977 and 1990.
