Development and Validation of HAS (Hajibandeh Index, ASA Status, Sarcopenia) - A Novel Model for Predicting Mortality After Emergency Laparotomy.

Objectives: To develop and validate a predictive model to predict the risk of postoperative mortality after emergency laparotomy taking into account the following variables: age, age ≥ 80, ASA status, clinical frailty score, sarcopenia, Hajibandeh Index (HI), bowel resection, and intraperitoneal contamination.

Summary Background Data: The discriminative powers of the currently available predictive tools range between adequate and strong; none has demonstrated excellent discrimination yet.

Methods: The TRIPOD and STROCSS statement standards were followed to protocol and conduct a retrospective cohort study of adult patients who underwent emergency laparotomy due to non-traumatic acute abdominal pathology between 2017 and 2022.

The risk of hepatic pseudoaneurysm after liver trauma in relation to the severity of liver injury: a meta-analysis and meta-regression analysis.

Aim: To determine the risk of hepatic pseudoaneurysm after liver trauma in relation to the severity of liver injury.

Methods: We performed a systematic review and meta-analysis in compliance with PRISMA statement standards (Registration Number: CRD42022328834). A search of electronic information sources was conducted to identify all studies reporting the risk of hepatic pseudoaneurysm after liver trauma.

Cohort study of long-term survival and recurrence patterns following operative management of colorectal liver metastasis - is follow-up beyond 5 years warranted?

Aims: To evaluate the patterns of overall survival (OS) and recurrence following surgical resection of colorectal liver metastases (CRLM).

Methods: In compliance with STROCSS guideline, a single-centre retrospective cohort study was conducted. All consecutive patients undergoing resection of CRLM between 2003 and 2019 were considered eligible for inclusion.

Partial ALPPS with a longer wait between procedures is safe and yields adequate future liver remnant hypertrophy.

Backgrounds/aims: Associating Liver Partition and Portal Vein Ligation for Staged Hepatectomy (ALPPS) has generated controversy due to high morbidity and mortality. We present our series of patients with 30-40% parenchymal transection and minimal hilar dissection.

Methods: Patients who had partial ALPPS between April 2015 and April 2016 were included.

Review of the diagnosis, classification and management of autoimmune pancreatitis.

Autoimmune pancreatitis (AIP) is a rare form of chronic pancreatitis, with as yet undetermined incidence and prevalence in the general population. Our understanding of it continues to evolve. In the last few years, 2 separate subtypes have been identified: type 1 AIP has been recognised as the pancreatic manifestation of a multiorgan disease, named immunoglobulin G4 (IgG4)-related disease while type 2 AIP is a pancreas specific disorder not associated with IgG4.
