Hemorrhage after Major Pancreatic Resection: Incidence, Risk Factors, Management, and Outcome

BACKGROUND AND AIMS

Hemorrhage is a rare but dreaded complication after pancreatic surgery. The aim of this study was to examine the incidence, risk factors, management, and outcome of postpancreatectomy hemorrhage in a tertiary care center.

MATERIALS AND METHODS

A retrospective observational study was conducted on 500 consecutive patients undergoing major pancreatic resections at our institution. Postpancreatectomy hemorrhage was defined according to the International Study Group of Pancreatic Surgery criteria.

RESULTS

A total of 68 patients (13.6%) developed postpancreatectomy hemorrhage. Thirty-four patients (6.8%) had a type A, 15 patients (3.0%) had a type B, and the remaining 19 patients (3.8%) had a type C bleed. Postoperative pancreatic fistula Grades B and C and bile leakage were significantly associated with severe postpancreatectomy hemorrhage on multivariable logistic regression. For patients with postpancreatectomy hemorrhage Grade C, the onset of bleeding was in median 13 days after the index operation, ranging from 1 to 85 days. Twelve patients (63.2%) had sentinel bleeds. Surgery lead to definitive hemostatic control in six of eight patients (75.0%). Angiography was able to localize the bleeding source in 8/10 (80.0%) cases. The success rate of angiographic hemostasis was 8/8. (100.0%). The mortality rate among patients with postpancreatectomy hemorrhage Grade C was 2/19 (10.5%), and both fatalities occurred late as a consequence of eroded vessels in association with pancreaticogastrostomy.

CONCLUSION

Delayed hemorrhage is a serious complication after major pancreatic surgery.Sentinel bleed is an early warning sign. Postoperative pancreatic fistula and bile leakage are important risk factors for severe postpancreatectomy hemorrhage.

Interventional treatment of children with portal hypertension secondary to portal vein occlusion

PURPOSE

To present methods and results of interventional treatment of children with portal hypertension (PH) secondary to portal vein occlusion (PVO).

MATERIAL AND METHODS

Five children, four boys and one girl, 8 - 14 years old, with symptomatic PH secondary to PVO were treated. All children had one or more episodes of bleeding from oesophageal varices, enlarged spleen and thrombocytopenia. Partial embolisation of the spleen was performed in four children. Attempts to recanalize the occluded part of the portal vein were done in all children using transjugular (n = 4), transhepatic (n = 4) and transsplenic (n = 3) approaches.

RESULTS

All procedures were carried out without serious complications and were followed by normalisation of the platelet count, decrease in splenic size and disappearance of bleeding. Recanalisation of the occluded portal vein with a stent was possible in one child and partial stent recanalisation was possible in another child. Transjugular intrahepatic portosystemic shunt (TIPS) with partly extrahepatic, intraperitoneal route was created in one patient. All children were scheduled for follow-up. During the observation time of 22 months (5 - 46 months), additional balloon dilation and placement of new stents were necessary in two children.

CONCLUSION

Interventional procedures are valuable in the treatment of children with symptoms secondary to PVO. Treatment should be customized and scheduled follow-ups of the patients are necessary.
