RESUMO

BACKGROUND: Laparoscopic subtotal cholecystectomy (LSTC) without cystic duct ligation is an alternative to conversion to open surgery in a difficult cholecystectomy, thus avoiding a potentially hazardous dissection in Calot's triangle. The long-term outcomes of this procedure are not well reported. The aim of this study is to assess the rates of re-presentation, re-admissions, endoscopic interventions and completion cholecystectomy in patients who have undergone LSTC. METHODS: Details of all patients undergoing cholecystectomy over a 13-year period (2003-2015) were entered on a prospective database. Further information on subsequent hospital attendances, biliary imaging, endoscopic interventions and re-operations following the index LSTC was collected retrospectively from hospital database. RESULTS: Overall, 2313 patients underwent laparoscopic cholecystectomy. Eighty-five patients (3.7%) underwent LSTC and the rest had standard laparoscopic cholecystectomy. A controlled bile leak was observed in 16 (19%) patients post-operatively, of which 3 resolved spontaneously. The remaining 13 were managed with an early endoscopic retrograde cholangiopancreatography (ERCP) and biliary stent. Twenty-seven patients (32%), who underwent LSTC, were re-investigated for the upper abdominal symptoms. The time range for re-investigation was 21 days-124 months. Eight patients underwent ERCP post-discharge, for suspected bile duct stones on radiological imaging. Two patients required open completion cholecystectomy for symptomatic stones in the gallbladder remnant. CONCLUSION: LSTC is a feasible and safe alternative to open surgery with acceptable long-term consequences and re-interventions.

RESUMO

While alcohol use disorder (AUD) is a highly heritable condition, the basis of AUD in families with a history of alcoholism is difficult to explain by genetic variation alone. Emerging evidence suggests that parental experience prior to conception can affect inheritance of complex behaviors in offspring via non-genomic (epigenetic) mechanisms. For instance, male C57BL/6J (B6) mice exposed to chronic intermittent vapor ethanol (CIE) prior to mating with Strain 129S1/SvImJ ethanol-naïve females produce male offspring with reduced ethanol-drinking preference, increased ethanol sensitivity, and increased brain-derived neurotrophic factor (BDNF) expression in the ventral tegmental area (VTA). In the present study, we tested the hypothesis that these intergenerational effects of paternal CIE are reproducible in male offspring on an inbred B6 background. To this end, B6 males were exposed to 6 weeks of CIE (or room air as a control) before mating with ethanol-naïve B6 females to produce ethanol (E)-sired and control (C)-sired male and female offspring. We observed a sex-specific effect, as E-sired males exhibited decreased two-bottle free-choice ethanol-drinking preference, increased sensitivity to the anxiolytic effects of ethanol, and increased VTA BDNF expression; no differences were observed in female offspring. These findings confirm and extend our previous results by demonstrating that the effects of paternal preconception ethanol are reproducible using genetically identical, inbred B6 animals.
