Predictors of re-bleeding after endoscopic hemostasis for delayed post-endoscopic sphincterotomy bleeding

AIM: To predict the re-bleeding after endoscopic hemostasis for delayed post-endoscopic sphincterotomy(ES) bleeding.METHODS: Over a 15-year period, data from 161 patients with delayed post-ES bleeding were retrospectively collected from a single medical center. To identify risk factors for re-bleeding after initial successful endoscopic hemostasis, parameters before, during and after the procedure of endoscopic retrograde cholangiopancreatography were analyzed. These included age, gender, blood biochemistry, comorbidities, endoscopic diagnosis, presence of periampullary diverticulum, occurrence of immediate postES bleeding, use of needle knife precut sphincterotomy, severity of delayed bleeding, endoscopic features on delayed bleeding, and type of endoscopic therapy.RESULTS: A total of 35 patients(21.7%) had rebleeding after initial successful endoscopic hemostasis for delayed post-ES bleeding. Univariate analysis revealed that malignant biliary stricture, serum bilirubin level of greater than 10 mg/d L, initial bleeding severity, and bleeding diathesis were significant predictors of rebleeding. By multivariate analysis, serum bilirubin level of greater than 10 mg/d L and initial bleeding severity remained significant predictors. Re-bleeding was controlled by endoscopic therapy in a single(n = 23) or multiple(range, 2-7; n = 6) sessions in 29 of the 35 patients(82.9%). Four patients required transarterial embolization and one went for surgery. These five patients had severe bleeding when delayed post-ES bleeding occurred. One patient with decompensated liver cirrhosis died from re-bleeding.CONCLUSION: Re-bleeding occurs in approximately one-fifth of patients after initial successful endoscopic hemostasis for delayed post-ES bleeding. Severity of initial bleeding and serum bilirubin level of greater than 10 mg/d L are predictors of re-bleeding.

Double balloon endoscopy increases the ERCP success rate in patients with a history of Billroth Ⅱ gastrectomy

AIM:To evaluate the effect of double balloon endoscope(DBE)on the endoscopic retrograde cholangio-pancreatography(ERCP)success rate in patients with a history of BillrothⅡ(BⅡ)gastrectomy.METHODS:From April 2006 to March 2007,32 patients with a BⅡgastrectomy underwent 34 ERCP attempts.In all cases,the ERCP procedures were started using a duodenoscope.If intubation of the afferent loop or reaching the papilla failed,we changed to DBE for the ERCP procedure(DBE-ERCP).We assessed the success rate of afferent loop intubation,reaching the major papilla,selective cannulation,possibility of therapeutic approaches,procedure-related complications,and the overall success rate.RESULTS:Among the 32 patients with a history of BⅡgastrectomy,the duodenoscope was successfully passed up to the papilla in 22 patients(69%),and cannulation was successfully performed in 20 patients(63%).Six patients(2 with failure in afferent loop intubation and 4 with failure in reaching the papilla)underwent DBE-ERCP.The DBE reached the papilla in all the 6 patients(100%)and selective cannulation was successful in 5 patients(83%).Four patients(67%)who had common bile duct stones were successfully treated.One patient underwent diagnostic ERCP only and the other one,in whom selective cannulation failed,was diagnosed with papilla cancer proven by biopsy.There were no complications related to the DBE.The overall ERCP success rate increased to 88%(28/32).CONCLUSION:The overall ERCP success rate increases with DBE in patients with a previous BⅡgastrectomy.

Coexistence of hepatoma with mantle cell lymphoma in a hepatitis B carrier

The coexistence of hepatocellular carcinoma(HCC) and non-Hodgkin's lymphoma(NHL) in the liver is rare. Reports show that these patients have cirrhotic livers or hepatitis virus infections before they develop HCC and NHL. We present a patient with hepatitis B virus infection who was transferred to our hospital with a newly detected liver mass; abdominal computed tomography examination showed one hypodense mass of 7 cm in diameter and multiple mesenteric and mediastinal lymph nodes. A liver tumor biopsy showed a hepatoma, and the pathologic findings from an inguinal lymph node excision showed mantle cell lymphoma. An immunohistochemical stain confirmed that the atypical lymphoid cells within the HCC were positive for the CD20, CD5 and cyclin D1 antigens. Taking these findings into account, the hepatic tumor was determined to be a HCC infiltrated by mantle cell lymphoma.
