The role of antibiotic prophylaxis in the initial management of patients with acute pancreatitis is an area of major controversy. Contrary to earlier clinical trials, recent experimental and clinical studies have accrued evidence that warrants reappraisal of current clinical practice. This article reviews these recent advances in knowledge. ⋯ Current experimental evidence favours the use of prophylactic antibiotics in severe acute pancreatitis. The results of contemporary randomized clinical trials restricted to patients with prognostically severe acute pancreatitis have demonstrated improvement in outcome associated with antibiotic treatment.

The survival of patients who underwent pancreaticoduodenectomy with or without en bloc resection of the superior mesenteric-portal vein (SMPV) confluence for adenocarcinoma of the pancreatic head was compared. ⋯ Patients with adenocarcinoma of the pancreatic head who require venous resection during pancreaticoduodenectomy for isolated tumour extension to the SMV or SMPV confluence (in the absence of tumour extension to the SMA or coeliac axis) have a duration of survival no different from that of patients who undergo standard pancreaticoduodenectomy. These data suggest that venous involvement is a function of tumour location rather than an indicator of aggressive tumour biology.

Pancreatic cancer resection is considered a high-risk procedure in patients aged 70 years or older. ⋯ Patients aged 70 years or more can benefit from pancreatic cancer resection similarly to younger patients.

The incidence of abdominal aortic aneurysm (AAA) has increased steadily during the past 30 years. ⋯ The decline in mortality rate and emergency procedures may result from a fall in the incidence of ruptured AAA, due to an increasing rate of elective surgery before 1992. The decline in elective procedures from 1992 may be due to a fall in the prevalence of AAA owing to high rates of elective surgery, or to a fall in the incidence of the disease itself.
