RESUMEN
PURPOSE: Post-operative pancreatic fistula (POPF) is perhaps one of most dreaded pancreatoduodenectomy-related complications. Various approaches to mitigate this risk have been explored, with conflicting results and no clear consensus on the comparative superiority of any one technique. We postulate that regardless of technique, the key to reducing POPF is a robust pancreatic anastomosis with careful apposition of tissues, in particular the duct-to-mucosa anastomosis. METHOD: We describe the fashioning of a pancreatojejunostomy with an external pancreatic stent in the setting of a high-risk anastomosis with help of a 10 × magnification surgical microscope. A technical description with a short, edited video is presented.

Rapid confirmation of dermatomycoses is desirable because it allows the clinician to initiate appropriate therapy without delay. The routine potassium hydroxide (KOH) wet-mount is cheap and rapid to use but this method lacks a color contrast. We offer a simple practical tip of adding Chicago Sky Blue (CSB) stain to KOH to highlight fungal elements and provide a color contrast that makes reading and interpretation simple, even for the novice.

BACKGROUND: Diverticula of the appendix (DA) are infrequent and their clinical implications are often overlooked. Several studies have found a significantly increased prevalence of neoplasms in appendiceal specimens with diverticula. Despite the potential clinical implications, there is a paucity of literature. A systematic review and meta-analysis was performed to evaluate the prevalence of DA and its association with neoplasia. METHODS: A systematic search of literature (Cochrane, EMBASE, PubMed and Medline) reporting the prevalence of DA and association with neoplasia was performed in November 2019. Relevant articles were assessed in accordance with the PRISMA guidelines. Risk of bias assessment was carried out using modified Newcastle-Ottawa scale. Meta-analysis with risk ratio and random-effects model was performed using RevMan. RESULTS: The initial search identified 1122 potential articles of which 11 were appropriate for quantitative analysis. The prevalence rate of DA was 1.74%. The mean age of patients with DA and those without DA was 41.2 and 33.9 years, respectively. The ratio of male to female was 1.8:1. The prevalence of neoplasia in specimens without DA versus those with DA was 1.28% and 26.94%, respectively. Only four studies addressed the prevalence of locoregional neoplasia in the setting of DA compared to control. Meta-analysis with random-effects model demonstrated that pooled risk ratio was 25.46 (95% confidence interval 12.77-50.75, P < 0.00001). CONCLUSION: The strong association with neoplasia in this meta-analysis reinforces the clinical significance of DA. Surgeons, pathologists and radiologists should be mindful of this uncommon pathology and consider individualized patient management, until further evidence can direct clinical guidelines for the management of patients with DA.
