/Objectives: A paradigm shift has been observed in the management of mild gallstone pancreatitis; current guidelines advocate definitive cholecystectomy on the index admission. Despite the abundance of published guidelines, uncertainty remains with regard to the timing of cholecystectomy in moderate and severe acute pancreatitis (MAP/SAP), and no definitive consensus has been declared. This systematic review aimed to evaluate the published guidelines and subsequent evidence quoted in order to determine the optimal timing for cholecystectomy in this high-risk patient cohort. A systematic review of published literature was performed using PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) and AMSTAR (Assessing the methodological quality of systematic reviews) guidelines, and included a search of three online electronic databases. Eleven guidelines were included. Only 4 (36%) of guidelines specified an actual time frame for surgical intervention. Delaying surgery for a minimum of 6 weeks was advocated by all 4 guidelines. All recommendations were based upon weak or very low-quality evidence. Higher mortality rates were observed when patients underwent early cholecystectomy for SAP (1.3-44%) when compared to patients who underwent delayed surgery (0-11%). Marked variation was observed amongst the published guidelines on the definitive management of MAP and SAP and disparity remains on the timing of cholecystectomy. A minority of the guidelines proposed a specific time period for when cholecystectomy should be performed, and whilst based on low quality evidence, delaying surgery (for 6 weeks) is associated with a reduction in morbidity and mortality rates and should be advocated in MAP/SAP until level 1 evidence becomes available.

We report a case of a 73-year-old woman who developed pancreatic adenocarcinoma and presented with a colonic obstruction due to isolated metastasis to the colon, the primary lesion being diagnosed subsequently on imaging. The histopathological findings of the pancreatic mass exhibited a morphology and immunohistochemical profile consistent with a pancreatic adenocarcinoma and led to further analysis of the colonic pathology which ultimately confirmed the lesion was a pancreatic metastases rather than a primary colonic carcinoma. As the pancreatic cancer had metastasised to the colon, it was inoperable. The patient continued on palliative chemotherapy and passed 7 months after presentation for evaluation of her pancreatic mass due to progression of the pancreatic cancer. This report demonstrates a rare presentation of pancreatic cancer with colonic obstruction due to isolated metastatic disease and illustrated the importance of careful evaluation of histopathological findings.

A 79-year-old woman presented to the emergency department following a motor vehicle collision. As part of her workup she underwent a CT scan which identified a large mass containing calcifications centred around the gastric antrum, and while being assessed she produced 500 mL of haematemesis. An endoscopy revealed an area of friable mucosa the nature of which was uncertain, and multiple biopsies revealed amyloid deposition and active Helicobacter pylori gastritis. Following review of imaging and pathology, a diagnosis of gastric mucosa-associated lymphoid tissue (MALT) lymphoma was established. She was treated with quadruple therapy for the H. pylori and at 6-month follow-up she is asymptomatic with repeat endoscopy revealing healing of the ulceration and no biopsy evidence of H. pylori or MALT.
