Manejo quirúrgico de la necrosis pancreática infectada. Serie de casos en un hospital de cuarto nivel en Bogotá, Colombia, 2014-2021

Abstract

Introduction: Pancreatitis is a frequent pathology in our environment, mostly related to benign biliary patho-logy. It can progress to severe forms in 10-15 % of cases, where the pancreatic tissue becomes necrotic and forms large collections with risk of infection. We do not have epidemiological data about the incidence or management of this complication in Colombia. Aim: This study aims to study the prevalence of infected pancreatic necrosis and describe the cases identified in a quaternary care hospital between 2014 and 2021. Materials and methods: A cross-sectional observational study. We analyzed records of patients diagnosed with stage 2 pancreatitis. Those cases with infected pancreatic necrosis that underwent debridement plus la-paroscopic and open surgical drainage at Hospital Universitario Mayor Méderi in Bogotá, Colombia, between January 2014 and January 2021 were studied. A convenience sampling was carried out without calculating the sample size. We collected the patients’ demographic and clinical variables, performing a descriptive statistical analysis in Excel. Qualitative variables were described through absolute and relative frequencies, while quan-titative ones were expressed through measures of central tendency and dispersion based on their distribution.Results: We analyzed 1020 episodes of pancreatitis, finding pancreatic necrosis in 30 patients, i.e., a period prevalence of 2.9 %. Of the patients, 83 % (n = 25) underwent open drainage, with 48 % (n = 12) mortality. About laparoscopic management, the reduction in postoperative organ failure was 40 % (n = 2), with a 30 % shorter hospital stay than the open drainage approach. Those patients with a level of procalcitonin (PCT) lower than 1.8 ng/mL had less mortality. Conclusions: The laparoscopic approach shows promising results regarding final morbidity and mortality
