The cases of 42 patients with malignant ascites treated with a peritoneal venous shunt over a 5-year period are reviewed to establish the incidence of surgical and postsurgical complications. Although the yield of malignant cells found in the peripheral blood was increased after shunting, no new hematogenous metastases were observed after the operation. No evidence of disseminated intravascular coagulation was observed after shunt placement. While the shunt effectively relieved the discomfort due to abdominal distention and respiratory impairment, no restoration of cutaneous hypersensitivity was observed in the nine patients who were anergic prior to surgery. The median survival of patients with breast and gynecological cancer, after surgery, was significantly longer than the survival of patients with primary gastrointestinal neoplasma. In conclusion, peritoneal venous shunt appears to be an effective and safe method to improve the quality of life of patients with malignant ascites.

The authors retrospectively analyse the results achieved in recent years by surgical treatment of 103 malignant primary or secondary liver cancers: (Three patients have been operated on twice at different times for recurrence.) 23 hepatic resections were performed for benign lesions. The operative mortality is very low, the incidence of postoperative complications is minimal, and the survival up to 8 years is rather satisfactory. In all cases we used Ton That Tung's surgical technique, that is, "finger fracture with intraparenchymal ligature of the vasculobiliary pedicles."

On the basis of 211 hepatic resections and reresections, a study was made to evaluate the possibility of compiling a checklist for primary liver tumours according to the TNM classification. This would aid the surgeon in planning therapy and provide a useful guide for prognosis and late results.
