Endoscopic treatment of biliopancreatic path.log. in patients with.Wh.pple's pancreaticoduodenectomy surg.cal variants: Lessons learned from sing.e-balloon enteroscopy-assisted ERCP

引用

h.patobiliary & Pancreatic Diseases International 2024年第5期23卷 509-514页

作者： Rodrig. g.rcés-Durán Laurent Monino Pierre h.Deprez h.bert Piessevaux Tom g.Moreels Department of g.stroenterolog. and h.patolog. Universitécatholique de LouvainCliniques Universitaires Saint-LucAvenue Hippocrates 101200 BrusselsBelgium

Backg.ound: Endoscopic treatment of biliopancreatic path.log. is ch.lleng.ng.due to surg.cally altered anatomy after Wh.pple's pancreaticoduodenectomy. Th.s study aimed to evaluate th. feasibility and safety of sing.e-balloon enteroscopy-assisted endoscopic retrog.ade ch.lang.opancreatog.aph.(SBE-ERCP) to treat biliopancreatic path.log. in patients with.Wh.pple's pancreaticoduodenectomy surg.cal variants. Meth.ds: We retrospectively analyzed 106 SBE-ERCP procedures in 46 patients with.Wh.pple's variants. Tech.ical and clinical success rates and adverse events were evaluated. Results: Biliary SBE-ERCP was performed in 34 patients and pancreatic SBE-ERCP in 17, including.5 with.both.indications. From a total of 106 SBE-ERCP procedures, 76 were biliary indication with.tech.ical success rate of 68/76(90%) procedures and clinical success rate of 30/34(88%) patients. Mild adverse event rate was 8/76(11%), with.ut serious adverse events. From a total of 106 SBE-ERCP procedures, 30 were pancreatic indication with.tech.ical success rate of 24/30(80%) procedures( P = 0.194 vs. biliary SBEERCP) and clinical success rate of 11/17(65%) patients( P = 0.016 vs. biliary SBE-ERCP). Mild adverse event rate was 6/30(20%)( P = 0.194 vs. biliary SBE-ERCP), with.ut serious adverse events. After SBE-ERCP failure, endoscopic ultrasound-g.ided drainag., percutaneous drainag. and redo surg.ry were alternative th.rapeutic options. Conclusions: Biliopancreatic path.log. after Wh.pple's pancreaticoduodenectomy variants can be treated using.SBE-ERCP with.ut serious adverse events. Tech.ical and clinical success rates are h.g. for biliary indications, wh.reas clinical success rate of pancreatic indications is sig.ificantly lower. SBE-ERCP can be considered as first-line treatment option in th.s patient g.oup with.surg.cally altered anatomy.

In th. urban atmosph.re of Beng.luru, various volatile org.nic compounds(VOCs), particularly Benzene,Toluene, Eth.lbenzene, and Xylene(BTEX), h.ve sh.wn an increasing.trend in concentration. Th. present research.was conducted during.summer and monsoon seasons, focusing.on Kadubeesanah.lli, a h.g.-traffic area with.n th. Beng.luru Metropolitan City. h.urly sample data was collected using.a BTEX analyzer(Model g.955-600) and subsequently transformed into daily, month.y, and seasonal values. Th. study revealed distinct patterns in benzene concentrations. Benzene levels were lowest during.th. early morning.h.urs, specifically from 1:00 *** 7:00 a.m.. Concentrations th.n increased from 7:00 a.m. to 9:00 a.m. and ag.in from 4:00 p.m. to 11:00 p.m.,corresponding.to th. morning.and evening.peak traffic h.urs. h.wever, between 10:00 a.m. and 4:00 p.m., th. concentration decreased due to reduced traffic levels. Th.se diurnal variations in benzene concentration are influenced by meteorolog.cal parameters. Comparing.th. two seasons, h.g.er concentrations of Benzene, Eth.lBenzene, and MP-xylene were observed during.th. summer season. Th.s increase is attributed to th. elevated temperatures during.summer, wh.ch.promote th. vaporization of BTEX compounds. Conversely, lower BTEX concentrations were recorded during.th. monsoon season due to th. wet deposition process. Th. observed positive correlation(r > 0.5) among.BTEX parameters strong.y sug.ests a common source, most likely orig.nating.from veh.cular emissions.
