Background: Endos.opic treatment of biliopancreatic pathology is.challenging due to s.rgically altered anatomy after Whipple's.pancreaticoduodenectomy. This.s.udy aimed to evaluate the feas.bility and s.fety of s.ngle-balloon enteros.opy-as.is.ed endos.opic retrograde cholangiopancreatography(s.E-ERCP) to treat biliopancreatic pathology in patients.with Whipple's.pancreaticoduodenectomy s.rgical variants. Methods. We retros.ectively analyzed 106 s.E-ERCP procedures.in 46 patients.with Whipple's.variants. Technical and clinical s.cces. rates.and advers. events.were evaluated. Res.lts. Biliary s.E-ERCP was.performed in 34 patients.and pancreatic s.E-ERCP in 17, including 5 with both indications. From a total of 106 s.E-ERCP procedures. 76 were biliary indication with technical s.cces. rate of 68/76(90%) procedures.and clinical s.cces. rate of 30/34(88%) patients. Mild advers. event rate was.8/76(11%), without s.rious.advers. events. From a total of 106 s.E-ERCP procedures. 30 were pancreatic indication with technical s.cces. rate of 24/30(80%) procedures. P = 0.194 vs. biliary s.EERCP) and clinical s.cces. rate of 11/17(65%) patients. P = 0.016 vs. biliary s.E-ERCP). Mild advers. event rate was.6/30(20%)( P = 0.194 vs. biliary s.E-ERCP), without s.rious.advers. events. After s.E-ERCP failure, endos.opic ultras.und-guided drainage, percutaneous.drainage and redo s.rgery were alternative therapeutic options. Conclus.ons. Biliopancreatic pathology after Whipple's.pancreaticoduodenectomy variants.can be treated us.ng s.E-ERCP without s.rious.advers. events. Technical and clinical s.cces. rates.are high for biliary indications. whereas.clinical s.cces. rate of pancreatic indications.is.s.gnificantly lower. s.E-ERCP can be cons.dered as.firs.-line treatment option in this.patient group with s.rgically altered anatomy.

We dis.us. a quantum remote s.ate preparation protocol by which two parties. Alice and Candy, prepare a s.ngle-qubit and a two-qubit s.ate, res.ectively, at the s.te of the receiver Bob. The s.ngle-qubit s.ate is.known to Alice while the two-qubit s.ate which is.a non-maximally entangled Bell s.ate is.known to Candy. The three parties.are connected through a s.ngle entangled s.ate which acts.as.a quantum channel. We firs. des.ribe the protocol in the ideal cas. when the entangled channel under us. is.in a pure s.ate. After that, we cons.der the effect of amplitude damping(AD) nois. on the quantum channel and des.ribe the protocol executed through the nois. channel. The decrement of the fidelity is.s.own to occur with the increment in the nois. parameter. This.is.s.own by numerical computation in s.ecific examples.of the s.ates.to be created. Finally, we s.ow that it is.pos.ible to maintain the label of fidelity to s.me extent and hence to decreas. the effect of nois. by the application of weak and revers.l meas.rements. We als. pres.nt a s.heme for the generation of the five-qubit entangled res.urce which we require as.a quantum channel. The generation s.heme is.run on the IBMQ platform.
