Medium-Term Outcomes from a Series of 1000 One Anastomosis Gastric Bypass in Australia: A Case Series.

Purpose: This study presents the short- (less than 6 months) and medium-term (6 months to 2 years) outcomes for weight loss and type 2 diabetes mellitus (T2DM) for all patients undergoing one anastomosis gastric bypass (OAGB) across multiple institutions between 2015 and 2021.

Materials And Methods: A retrospective analysis of prospectively collected databases was performed including 1022 participants who underwent OAGB at multiple institutions by multiple surgeons between 2015 and 2021. Primary outcome was percentage total weight loss (TWL) and secondary outcomes were achieving resolution of T2DM; OAGB specific short- and medium-term complications including bile reflux, marginal ulceration and internal herniation.

The association between KRAS and histopathological growth patterns and the impact on resection margins around vasculature and bile ducts in colorectal liver metastases.

The liver is the most frequent and often the only site of distant disease in colorectal cancer and, of all treatment protocols currently in use, resection is the most likely to result in long-term cure. Within the liver, tumour proximity to major vasculature and biliary structures poses a resection challenge, requiring a balance of achieving negative margins while preserving adequate vascular circulation and biliary drainage. The focus on parenchymal sparing resections are important but just as important may be the 'biological' behaviour of the tumour.

Loop and drain technique for prevention of surgical site infection in upper gastrointestinal surgery.

Introduction: Hepatobiliary and pancreatic surgery is frequently complicated by surgical site infections (SSI) with significant postoperative morbidity and mortality rates contributing to the economic burden on healthcare. Advancements in operative techniques to prevent SSI are gaining traction in clinical practice. This study compares the effectiveness of the 'loop and drain technique (LDT)', a combination method utilizing a continuous subcutaneous vessel loop and subcuticular suture for surgical wound closure in patients undergoing upper gastrointestinal surgery at a Metropolitan Hospital in Sydney.

Older trauma patients are at high risk of delirium, especially those with underlying dementia or baseline frailty.

Background: Given the increasing numbers of older patients presenting with trauma, and the potential influence of delirium on outcomes, we sought to investigate the proportion of such patients who were diagnosed with delirium during their stay-and patient factors associated therewith-and the potential associations between delirium and hospital length of stay (LOS). We hypothesized that delirium would be common, associated with certain patient characteristics, and associated with long hospital LOS (highest quartile).

Methods: We conducted a retrospective observational cohort study of all trauma patients aged ≥65 years presenting in September to October 2019, interrogating medical records and the institutional trauma database.
