Application of a diagnostic algorithm for differential diagnosis in a patient with recurrent abdominal pain

Abstract

Introduction Among the diseases of urgent pathology the leading place belongs to acute pancreatitis, which is second only to acute appendicitis and acute cholecystitis. Moreover, a significant share is occupied by mild forms, which account for 85%. In the Clinical Recommendations for Acute pancreatitis in the section “Prevention and dispensary monitoring”, the authors recommend regular dispensary monitoring by a gastroenterologist and a surgeon. However, this nosology according to the Order of the Ministry of Health of the Russian Federation from 03.15.2022 No 168N is not included in the dispensary observation. In this regard, patients remain without proper attention of doctors when they are discharged from hospitals, or when they refuse hospitalization after examination in the emergency room.The aim of the work – is to present the result of applying the diagnostic algorithm of differential diagnosis of diseases and detection of gastrointestinal tract pathology on the clinical example of a patient with recurrent abdominal pain syndrome.Materials and methods The analysis of medical records of a 59-year-old patient who repeatedly applied to the network of polyclinics and hospitals providing emergency specialized medical care for recurrent abdominal syndrome was carried out.Results and discussion In this clinical observation of recurrent abdominal syndrome in a patient, the biliary mask of acute pancreatitis was revealed. In outpatient conditions using the developed diagnostic algorithm, choledocholithiasis, juxtapapillary diverticulum of the duodenum and hernia of the esophageal aperture of the diaphragm were detected. The diagnosis made it possible to perform the treatment competently and lead to the patient's recovery. Thanks to the dispensary observation and additional methods of investigation according to the developed algorithm, the following were detected: juxtapapillary diverticulum of the duodenum, which may not be visualized at video esophagogastroduodenoscopy with direct optics, as well as ductal stones, which are not always visualized at transabdominal ultrasound and are detected at endoscopic retrograde cholangiopancreatography or endoscopic ultrasonography. Difficulties may arise in the diagnosis of gastrointestinal diseases due to the variability of the clinical course and polymorphism of symptoms in this category of patients. Such a course of diseases causes difficulties at the stage of patients' admission to the emergency room of clinics, can lead to diagnostic errors that lead to incorrect treatment tactics.Conclusion The application of an algorithm based on the assessment of clinical criteria in conjunction with instrumental imaging methods and laboratory tests allowed to optimize the diagnostic process and facilitated the choice of optimal therapy and surgical tactics for the treatment of the patient with recurrent abdominal pain syndrome.
