BackgroundSeveral methods have been suggested to treat the hepatic raw surface after resection. Among these, omentoplasty (OP) has been employed occasionally but there are no clinical studies that clearly demonstrate its usefulness.MethodsOf 172 randomized patients undergoing hepatic resection between January 1991 and December 1994, 5 were withdrawn for protocol violation, leaving 167 who were randomly allotted to undergo OP (n = 87) on the hepatic raw surface or not (NO; n = 80). This procedure was performed for malignant tumor in 125 cases, benign tumor in 33, and for other causes in 15. Six patients had more than two types of lesions, and 32 patients had associated cirrhosis. Sixty-five major and 102 minor hepatic resections were performed. The main outcome measures studied were the number of patients with deep abdominal complications (DAC; deep bleeding or hematoma, deep infection, with or without pus discharge through drains, bile leakage), as well as repeat operations and postoperative death. Patients were divided into two strata according to the site of the lesion with respect to the diaphragm: (1) in contact (posterosuperior segments II, VII and VIII) or (2) not in contact (anterior segments III, IV, V, and VI).ResultsBoth groups were comparable as regards patient demographics, intraoperative procedures, intraoperative search for bile leaks and intraoperative transfusion requirements. Fewer patients had DAC in OP (n = 11) than in NO (n = 15) (difference not significant). Ten patients (6%) required repeat operations: 4 in OP without immediate mortality and 6 in NO, 3 followed by death. One further patient in OP required repeat operation after discharge and died. Four patients died in OP and 7 in NO, 1 and 4 of DAC, respectively (not significant). Deep abdominal complications were significantly associated with major hepatic resection (P <0.05) whereas postoperative death was significantly correlated with cirrhosis (P <0.05).ConclusionsOP on the raw surface after hepatic resection lowers the rate of all complications related to DAC (except biliary leaks) and their severity (repeat operations and death) but not significantly so. OP is not recommended as a routine measure to complete elective hepatic resections.
