Synchronous gangrenous cholecystitis and appendicitis secondary to appendiceal diverticulum perforation.

Acute appendicitis and acute cholecystitis are among the commonest pathologies in acute general surgery. They are characterized by distinct symptoms, clinical examination findings and typical elements of the history which direct further investigations. In the absence of these classic findings, these diagnoses can be missed, particularly where they occur synchronously.

Association of Obesity With Septic Complications After Major Abdominal Surgery: A Secondary Analysis of the RELIEF Randomized Clinical Trial.

Importance: Body mass index (BMI) has been the most common obesity measure to assess perioperative risk; however, cardiometabolic risk is associated with the burden of visceral fat. Definitive evidence on the association of visceral fat measures, such as waist circumference and waist-to-hip ratio (WHR), with postoperative complications is lacking.

Objective: To compare the value of waist circumference with the value WHR and BMI in predicting adverse outcomes, including major septic complications and persistent disability, following major abdominal surgery.

Development of a pelvic exenteration service at a tertiary referral centre.

Background: Over one-third of primary rectal cancers are locally advanced at diagnosis, and local recurrence of rectal cancer occurs at a rate of 3-10% following primary curative resection. Extended resectional surgery, including pelvic exenteration, is the only proven therapy with curative potential in the treatment of these cancers along with many other pelvic malignancies. A microscopically clear resection margin (R0 resection) is the predominant prognostic factor affecting overall and disease-free survival.
