Duodenoportal fistula caused by peptic ulcer after extended right hepatectomy for hilar cholangiocarcinoma

BACKGROUND: A fistula between the duodenum and the main portal vein near a peptic ulcer is extremely rare, and only two cases of duodenal ulcers have been reported in the past. CASE PRESENTATION: We report a 68-year-old man with a diagnosis of anemia who had a history of extended right hepatectomy for hilar cholangiocarcinoma 20 months previously. The first endoscopic examination revealed a giant peptic ulcer with active bleeding at the posterior wall of the duodenal bulbs, and hemostasis was performed. Endoscopic treatment and transarterial embolization were performed repeatedly because of uncontrollable bleeding from the duodenal ulcer. Nevertheless, he died of sudden massive hematemesis on the 20(th )hospital day. At autopsy, communication with the main portal vein and duodenal ulcer was observed. CONCLUSION: It should be borne in mind that the main portal vein is exposed at the front of the hepatoduodenal ligament in cases with previous extrahepatic bile duct resection

C-Reactive protein is an independent surgical indication marker for appendicitis: a retrospective study

<p>Abstract</p> <p>Background</p> <p>This study is an attempt to clarify the role of C-reactive protein (CRP) as a surgical indication marker for appendicitis.</p> <p>Methods</p> <p>One hundred and fifty patients who underwent appendectomies and had pathologically confirmed appendicitis were reviewed between May 1, 1999 and September 31, 2007. The correlation between preoperative clinical factors and the actual histological severity, and identify surgical indication markers were assessed by univariate and multivariate analyses.</p> <p>Results</p> <p>Univariate analysis showed that only the CRP level significantly differ between the surgical treatment necessary group (gangrenous appendicitis) and the possible non-surgical treatment group (catarrhalis and phlegmonous appendicitis). Multivariate analysis indicated only the CRP level to be a surgical indication marker for acute appendicitis. The receiver-operating characteristic (ROC) curve indicated that the cutoff value of CRP for surgical indication of appendicitis is 4.95 mg/dl.</p> <p>Conclusion</p> <p>Only the CRP level is consistent with the severity of appendicitis, and considered to be a surgical indication marker for acute appendicitis.</p
