Surgical results of perforated gastric carcinoma: An analysis of 155 Japanese patients

Objectives: Free perforation of gastric carcinoma accounts for less than 1% incidence of acute abdominal crisis in Japan, and this problem occurs much less frequently in Western countries. To clarify the characteristics of patients with perforated gastric carcinoma (PGC) and to investigate a treatment of choice, we reviewed the data of Japanese patients with PGC. Methods: A total of 155 cases of PGC reported in the Japanese literature from 1985 to 1994, including one patient of our own experience, were studied. The clinicopathologic features, including tumor stage and patient survival, were analyzed. Results: There were 27 stage I tumors (19%), 16 stage [I tumors (12%), 42 stage III tumors (30%), and 55 stage IV tumors (39%). Emergency gastrectomy was done in 128 patients (83%), with the mortality and 5-yr survival rate was 7 and 40%, respectively. The survival of patients was influenced by the gross type of tumor, serosal invasion, lymph node metastasis, stage of the disease, and operative curability. The 5-yr survival rate of stage I and II patients was 76% and that of curatively treated patients was 74%. Conclusions: Recent Japanese results of emergency gastrectomy for PGC are satisfactory. Long-term survival is expected in curatively treated patients with stage I and II tumors.
