Management of perforated gastric carcinoma: a report of 16 cases and review of world literature.

Perforated gastric carcinoma is rare; however, it is a serious condition associated with complications. To understand the proper management of this disease and to characterize its clinical course we reviewed available data on 16 patients with perforated gastric carcinoma. We collected data on the age and sex of the patients as well as operative findings and histological features of the primary tumor. The depth of invasion and presence of lymph node metastasis were also recorded. The Union Internationale Contre Cancer stage, extent of resection, and surgical method used were reviewed. We also reviewed published information on the management of perforated gastric carcinoma. The carcinoma was stage I in three cases, stage II in one case, stage III in three cases, and stage IV in nine cases. Many patients had distant metastases. Fourteen patients underwent gastrectomy. Two patients whose preoperative condition was poor died of surgery-related complications, but patients with early-stage carcinoma underwent an R0 resection (resection of the primary tumor with negative margins) and had minimal complications. We conclude that the outcome of patients who were able to undergo radical surgery was good and correlated with the stage of cancer. It is important to perform gastrectomy rather than repair the perforation first, and a proper lymphadenectomy should follow--thus a two-step surgery when necessary.
