Background: Cholecystectomy is considered a general surgical operation. However, general surgeons are not trained to manage severe complications such as bile duct injury(BDI) and should refer to hepatopancreatobiliary(HPB) surgeons when difficulty arises. This study aimed to investigate the outcomes of patients who had on-table HPB consults during cholecystectomy. Methods: This is an audit of 50 patients who required on-table HPB consult during cholecystectomy from 2011 to 2017. Consultations were classified as “proactive” and “reactive”, where consults were made before or after surgical incision, respectively. Patient demographics and perioperative details were collected. Results: The median age of the patients was 62.5 years [interquartile range(IQR) 50.8–71.3 years]. Eight(16%) patients had underlying HPB co-morbidity. Gallbladder wall was thickened in all patients(median 5 mm, IQR 4–7 mm), and common bile duct was of normal caliber in all patients(median 5 mm, IQR 4–6 mm). Median length of operation and length of stay were 165 min(IQR 124–209 min) and five days(IQR 3–7 days), respectively. Subtotal cholecystectomy was performed in 18(36%) patients. Forty-eight patients were initially managed by laparoscopic approach, 15(31%) required open conversion;majority(9/15, 60%) were initiated before on-table consult. Majority of referrals(98%) were reactive. Common reasons for referral included unclear anatomy or anatomical variations(30%), presence of dense adhesions and/or contracted gallbladder(18%) and impacted stones in Hartmann’s pouch(16%). Three(6%) patients were referred for BDI(2 Strasberg D and 1 Strasberg E1), and two(4%) were referred for torrential bleeding from arterial injury(1 cystic artery and 1 right hepatic artery). Any morbidity and 30-day readmission were 22% and 6%, respectively. There was no 90-day mortality. Conclusions: Calling for help in BDI is obligatory, but in other instances is a personal choice. Calling for help prior to open conversion i

Intensification of pollution loading worldwide has promoted an escalation of different types of disease-causing microorganisms, such as harmful algal blooms(HABs), instigating detrimental impacts on the quality of receiving surface waters. Formation of unwanted disinfection by-products(DBPs) resulting from conventional disinfection technologies reveals the need for the development of new sustainable alternatives. Quaternary Ammonium Compounds(QACs) are cationic surfactants widely known for their effective biocidal properties at the ppm level. In this study, a novel silica-based antimicrobial nanofilm was developed using a composite of silica-modified QAC(Fixed-Quat) and applied to a fiberglass mesh as an active surface via sol–gel technique. The synthesized Fixed-Quat nanocoating was found to be effective against E. coli with an inactivation rate of 1.3 × 10^(-3) log reduction/cm min. The Fixed-Quat coated fiberglass mesh also demonstrated successful control of Microcystis aeruginosa with more than 99% inactivation after 10 hr of *** developed antimicrobial mesh was also evaluated with wild-type microalgal species collected in a water body experiencing HABs, obtaining a 97% removal efficiency. Overall,the silica-functionalized Fixed-Quat nanocoating showed promising antimicrobial properties for water disinfection and HABs control, while decreasing concerns related to DBPs formation and the possible release of toxic nanomaterials into the environment.
