A cohort study on the risk of hepatectomy and pancreatectomy after history of abdominal surgery on other organs

Backgrounds/Aims The present study analyzed the postoperative outcomes in patients who underwent hepatectomy or pancreatectomy, with a history of intra-abdominal surgery involving other organs, to elucidate surgical efficacy. Methods We examined the perioperative parameters in 28 patients who underwent hepatectomy (n=12) and pancreatectomy (n=16) after receiving prior abdominal organ resection (esophagectomy, n=2; gastrectomy, n=5; resection of small intestine, n=2; appendectomy, n=5; colorectal resection, n=9; hepatectomy, n=1; cholecystectomy, n=3; splenectomy, n=2, pancreatectomy ,right adrenectomy, nephrectomy and myoma uteri, n=1 each). Results Age, gender, a history of comorbidities, and primary diseases were not significantly different between the groups. The present operation was predominantly indicated for liver metastases in all patients undergoing hepatectomy. Several diseases were detected in pancreaticoduodenectomy (PD) patients. Laboratory data were not significantly different between groups. Although operating time and blood loss during hepatectomy did not differ significantly between the groups, the operating time was significantly longer in patients undergoing PD compared with distal pancreatectomy (p<0.05). Red cell blood transfusion was most frequently used in patients who underwent major hepatectomy and PD (p<0.05). The prevalence of postoperative complications was not significantly different between groups. Hospital death was not observed and the period of hospital stay did not differ between groups. Conclusions Carefully scheduled hepatectomy or pancreatectomy is safe even in cases with prior abdominal surgery under the present strategy.
