Analysis and prevention of postoperative delayed hemorrhage associated with radical D2 gastrectomy / 中国肿瘤临床

ABSTRACT

Objective:To investigate the cause, treatment, and prognosis of delayed hemorrhage in patients who underwent radical gastrectomy. Methods:The clinical data of 294 patients who underwent radical gastrectomy in the Second Hospital Affiliated from Nanchang University from January 2015 to October 2015 were retrospectively analyzed. Results:A total of 15 patients suffered from delayed hemorrhage and accounted for 5.1%of the gastric cancer cases in our hospital for the same period of radical gastrectomy. Of the 15 patients, 9 underwent laparoscopic radical gastrectomy and 6 received open radical gastrectomy resection. Large vascular hemorrhage was found in 7 cases. Anastomosis and anastomotic ulcer induced hemorrhage were observed in 3 cases. Duodenal stump rupture induced hemorrhage was detected in 2 cases. Hemorrhage was also observed in some parts in 2 cases. Likewise, hemorrhage occurred in 1 case, but the affected parts were unknown. Of the 11 patients who underwent a second operation, 2 were subjected to digital subtraction angiography (DSA) and transcathete arterial embolization (TAE) to stop hemorrhage. Endoscopic hemostasis was performed to stop hemorrhage in 1 case. Conservative treatment was administered to stop hemorrhage in 1 case. The secondary surgery rate was 73.3%(11/15) with mortality and curative rates of 40%(6/15) and 60%(9/15), respectively. Conclusion:For delayed hemorrhage after D2 of gastric cancer, a second radical surgery and death rates were high. Therefore, patients suffering from hemorrhage should be subjected to comprehensive clinical treatment and positive measures. Major vascular bleeding, anastomotic leakage, anastomotic ulcer, and duodenal stump rupture are relevant risk factors. Anastomotic fistula and celiac artery bleeding complications caused hemorrhage is the leading cause of death. Extensive bleeding and unstable vital signs should be checked. A second operation and abdominal drainage should also be timely conducted to as effective methods. Realistic and conservative treatment can be administered to patients with stable vital signs and low amount of blood loss. Endoscopic hemostasis can be applied to alleviate simple anastomotic ulcer bleeding. DSA can be initially performed to detect unknown bleeding sites. TAE can be subsequently used to treat hemorrhage.
