Aberrant Right Hepatic Duct Draining into the Cystic Duct: Clinical Outcomes and Management
Background. Aberrant right hepatic duct (ARHD) draining into
cystic duct (CD) is relatively rare but clinically important
because of its susceptibility to injuries during cholecystectomy.
These injuries are often-times missed or diagnosed late and as a
result can develop serious complications. Methods. Four
consecutive patients diagnosed with ARHD draining into CD were
identified for inclusion. Results. The mean age of patients was
42.5 years. The diagnosis in one of the patient was incidental
during a routine endoscopic retrograde cholangiopancreatography
(ERCP). Other three patients were diagnosed post-cholecystectomy-
one presented with suspected intra-operative biliary injury, one
with persistent bile leak and another with recurrent cholangitis.
Inadequate filling of the segment of liver on ERCP with dilation
of intrahepatic ducts in the corresponding segment on imaging was
present in two patients with complete obstruction of ARHD which
was managed surgically. In another patient, the partially
obstructed ARHD was managed by endoscopic therapy. Conclusion.
ARHD draining into the CD can have varied clinical manifestations.
In appropriate clinical settings, it should be suspected in
patients with persistence of bile leak early after
cholecystectomy, segmental dilation of intrahepatic-bile ducts on
imaging and paucity of intrahepatic filling in a segment of liver
on ERCP
Bouveret's syndrome complicated by distal gallstone ileus after laser lithotropsy using Holmium: YAG laser
BACKGROUND: Bouveret's syndrome is an unusual presentation of duodenal obstruction caused by the passage of a large gallstone through a cholecystoduodenal fistula. Endoscopic therapy has been used as first-line treatment, especially in patients with high surgical risk. CASE PRESENTATION: We report a 67-year-old woman who underwent an endoscopic attempt to fragment and retrieve a duodenal stone using a Holmium: Yttrium-Aluminum-Garnet Laser (Ho:YAG) which resulted in small bowel obstruction. The patient successfully underwent enterolithotomy without cholecystectomy or closure of the fistula. CONCLUSION: We conclude that, distal gallstone obstruction, due to migration of partially fragmented stones, can occur as a possible complication of laser lithotripsy treatment of Bouveret's syndrome and might require urgent enterolithotomy
Lubiprostone plus PEG electrolytes versus placebo plus PEG electrolytes for outpatient colonoscopy preparation: a randomized, double-blind placebo-controlled trial
Bowel preparation using large volume of polyethylene glycol (PEG) solutions is often poorly tolerated. Therefore, there are ongoing efforts to develop an alternative bowel cleansing regimen that should be equally effective and better tolerated. The aim of this study was to assess the efficacy of lubiprostone (versus placebo) plus PEG as a bowel cleansing preparation for colonoscopy. Our study was a randomized, double-blind placebo-controlled design. Patients scheduled for screening colonoscopy were randomized 1:1 to lubiprostone (group 1) or placebo (group 2) plus 1 gallon of PEG. The primary endpoints were patient\u27s tolerability and endoscopist\u27s evaluation of the preparation quality. The secondary endpoint was to determine any reduction in the amount of PEG consumed in the lubiprostone group compared with the placebo group. One hundred twenty-three patients completed the study and were included in the analysis. There was no difference in overall cleanliness. The volume of PEG was similar in both the groups. The volume of PEG approached significance as a predictor of improved score for both the groups (P = 0.054). Lubiprostone plus PEG was similar to placebo plus PEG in colon cleansing and volume of PEG consumed. The volume of PEG consumed showed a trend toward improving the quality of the colon cleansing

SARS-CoV-2 vaccination modelling for safe surgery to save lives: data from an international prospective cohort study
Background Preoperative SARS-CoV-2 vaccination could support safer elective surgery. Vaccine numbers are limited so this study aimed to inform their prioritization by modelling. Methods The primary outcome was the number needed to vaccinate (NNV) to prevent one COVID-19-related death in 1 year. NNVs were based on postoperative SARS-CoV-2 rates and mortality in an international cohort study (surgical patients), and community SARS-CoV-2 incidence and case fatality data (general population). NNV estimates were stratified by age (18-49, 50-69, 70 or more years) and type of surgery. Best- and worst-case scenarios were used to describe uncertainty. Results NNVs were more favourable in surgical patients than the general population. The most favourable NNVs were in patients aged 70 years or more needing cancer surgery (351; best case 196, worst case 816) or non-cancer surgery (733; best case 407, worst case 1664). Both exceeded the NNV in the general population (1840; best case 1196, worst case 3066). NNVs for surgical patients remained favourable at a range of SARS-CoV-2 incidence rates in sensitivity analysis modelling. Globally, prioritizing preoperative vaccination of patients needing elective surgery ahead of the general population could prevent an additional 58 687 (best case 115 007, worst case 20 177) COVID-19-related deaths in 1 year. Conclusion As global roll out of SARS-CoV-2 vaccination proceeds, patients needing elective surgery should be prioritized ahead of the general population.The aim of this study was to inform vaccination prioritization by modelling the impact of vaccination on elective inpatient surgery. The study found that patients aged at least 70 years needing elective surgery should be prioritized alongside other high-risk groups during early vaccination programmes. Once vaccines are rolled out to younger populations, prioritizing surgical patients is advantageous
