acute abdomen pain guidelines

OBJECTIVES: The aim of this study was to examine the clinical features of acute terminal ileitis in children and evaluate its rate before and during the COVID-19 pandemic. METHODS: This retrospective study was performed in our pediatric emergency department between 2018 and 2022. The records of 5363 patients who required abdominal imaging due to acute abdomen were analyzed, and 143 patients with terminal ileitis were included. The rate and etiological causes were compared during and before the COVID-19 pandemic...

The creatine kinase (CK) enzyme and its isoenzymes hold significant diagnostic value, appearing in distinct patterns across various tissues. The most common method for creatine kinase MB (CK-MB) estimation is based on immunoinhibition. However, this method can report falsely elevated CK-MB levels in various scenarios. Persistently elevated CK-MB levels or discrepancies between measured values and the patient's clinical condition warrant further investigation, such as total CK isoenzyme electrophoresis. This report presents a case where a patient was diagnosed with acute myocardial infarction and treated according to established guidelines...

Gastrointestinal stromal tumors (GISTs) are rare tumors accounting for 0.1-3% of gastrointestinal (GI) neoplasms. ‏In the past, GIST was classified as leiomyomas, leiomyosarcomas, and leiomyoblastomas. However, now it is evident that GIST is a separate tumor entity, and it is the most frequent sarcoma of the GI tract. We report a case of a 57-year-old female with a five-day history of black tarry stools, two episodes of vomiting of dark-colored blood, dizziness, abdominal pain, night sweats, and palpitation, provoked by a change of position...

Meckel's diverticulum (MD) is the most common congenital anomaly of the gastrointestinal tract with a 1-3% prevalence in the general population. The surgical management of symptomatic MD is well described in the literature, but there is still no consensus on the indication for prophylactic resection of incidental asymptomatic MD. To address this issue, we extensively reviewed the current literature and report our experience with laparoscopic management of an unusual case of MD causing ileal volvulus and acute peritonitis two weeks after a laparoscopic appendectomy for acute gangrenous appendicitis performed in another hospital...

BACKGROUND: An estimated 119,300 new cases of cervical cancer occur annually in China, accounting for 372,00 deaths. Cutaneous metastasis from cervical cancer is a rare event, with an incidence of 0.1-1.3% and typically a preterminal occurrence. Scalp metastasis from cervical cancer is exceptionally anecdotal, with only a dozen examples well documented. CASE PRESENTATION: The patient is a 33-year-old Chinese woman who was diagnosed with International Federation of Gynecology and Obstetrics stage IVB cervical cancer in November 2021...

Malignant psoas syndrome (MPS) is a rare and underreported clinical syndrome that significantly impacts the quality of life of cancer patients through metastatic infiltration of the iliopsoas muscle. Patients suffering from MPS often present with painful hip flexion, loss of mobility, and immense pain in their legs and back. The current literature describing the clinical presentation, management, and prognosis of MPS is limited primarily to case reports and outdated literature reviews. There remains a gap in the current knowledge of MPS and in the management of this complex cancer-related pain syndrome...

Acute right upper quadrant pain is one of the most common presenting symptoms in hospital emergency departments, as well as outpatient settings. Although gallstone-related acute cholecystitis is a leading consideration in diagnosis, a myriad of extrabiliary sources including hepatic, pancreatic, gastroduodenal, and musculoskeletal should also be considered. This document focuses on the diagnostic accuracy of imaging studies performed specifically to evaluate acute right upper quadrant pain, with biliary etiologies including acute cholecystitis and its complications being the most common...

Acute liver injury in the setting of acute fulminant hepatitis caused by the hepatitis B virus (HBV) can occur both during primary infection and after chronic HBV reactivation. Guidelines recommend considering antiviral therapy in both cases. Antiviral therapy with a nucleoside analog may be beneficial in patients with acute liver failure from acute HBV infection, though not all studies have shown a benefit. This is a case of a 53-year-old woman with a past medical history of untreated hepatitis C with undetectable viral load and right breast cancer status post lumpectomy, who presented to the emergency department with complaints of yellowish skin and sclera discoloration with right upper quadrant pain for one week...

A 67-year-old female presented to the emergency department with acute-onset severe left flank pain as well as nausea and vomiting. Physical examination was notable for left-sided abdominal, flank tenderness, and costovertebral angle tenderness. Laboratory workup revealed an elevated lactate of 9.2 mmol/L and elevated serum creatinine of 1.14 mg/dL, with an estimated glomerular filtration rate of 53 mL/minute/1.73m2 . Urinalysis showed moderate leukocyte esterase with microscopy showing 12 white blood cells and three red blood cells per high-power field...

Chylous ascites (CA) are a rare finding of triglyceride-rich peritoneal fluid within the abdominal cavity. Malignancy, cirrhosis, and trauma after abdominal surgery are the leading causes of CA in adults. Currently, there are no published guidelines on the management of CA. This report describes a case of an 18-year-old female presenting with abdominal pain and distention following median arcuate ligament syndrome (MALS) decompression. A computed tomography (CT) of the abdomen and pelvis showed large-volume ascites with normal hepatic morphology...

Cyclic vomiting syndrome (CVS) is a chronic disorder of gut-brain interaction characterized by recurrent disabling episodes of nausea, vomiting, and abdominal pain. CVS affects both children and adults with a prevalence of approximately 2% in the United States. CVS is more common in female individuals and affects all races. The pathophysiology of CVS is unknown and a combination of genetic, environmental, autonomic, and neurohormonal factors is believed to play a role. CVS is also closely associated with migraine headaches and likely have a shared pathophysiology...

BACKGROUND: Diverticular disease of the colon represents a common clinical condition in the western world. Its prevalence increases with age and only 5% of cases occur in adults younger than 40 years of age, making it a rare condition during pregnancy. The aim of this review was to provide an overview of the reported cases of diverticulitis during pregnancy. METHODS: We conducted a systematic review of the literature based on preferred reporting items for systematic review and meta-analysis (PRISMA) guidelines...

Background Abdominal radiography is one of the most routinely performed radiological investigations in hospitals. It is one of the initial investigations done in hospitals. Numerous studies have shown that abdominal X-rays have low sensitivity in several conditions such as acute abdominal pain. Methodology This study aims to first identify whether the Royal College of Radiology guidelines are being adhered to while requesting abdominal X-rays and, second, to identify the number of unnecessary requests made in the Betsi Cadwaladr health board...

BACKGROUND:  Radiologic care for children and adolescents during night and weekend shifts is challenging. This is especially true when a dedicated pediatric radiology front or background service is not available. METHODS:  The purpose of this review is to present the approach, the most relevant diagnoses, and their differential diagnoses based on four common example cases - abdominal pain, respiratory/chest pain, headache, and refusal to walk. Essentials such as clinical classification (e...

BACKGROUND: Patients presenting with acute abdominal pain that occurs after months or years following bariatric surgery may present for assessment and management in the local emergency units. Due to the large variety of surgical bariatric techniques, emergency surgeons have to be aware of the main functional outcomes and long-term surgical complications following the most performed bariatric surgical procedures. The purpose of these evidence-based guidelines is to present a consensus position from members of the WSES in collaboration with IFSO bariatric experienced surgeons, on the management of acute abdomen after bariatric surgery focusing on long-term complications in patients who have undergone laparoscopic sleeve gastrectomy and laparoscopic Roux-en-Y gastric bypass...

Acute abdominal pain is a common cause of ED visits and often requires imaging to identify a specific diagnosis. Prompt and appropriate imaging plays a crucial role in patient management and leads to improved patient outcomes, decreased hospital stay, and improved ED workflow. There are many cases of abdominal pain in the ED with delayed diagnosis and management secondary to a combination of institutional policies and knowledge deficits in current imaging guidelines. Inappropriate use of abdominal radiographs, use of oral contrast for CT abdomen and pelvis, and concern for iodinated contrast-induced acute kidney injury are three of the more commonly encountered roadblocks to prompt imaging diagnosis of abdominal pain...

This review focuses mainly on the imaging diagnosis, treatment, and complications of acute cholecystitis which is the most common benign disease of the gallbladder. The American College of Radiology appropriateness criteria for the imaging evaluation of patients with right upper quadrant pain and the Tokyo Guidelines for evaluating patients with acute cholecystitis and acute cholangitis are presented. The recent articles for using US, CT, MR, and HIDA in the evaluation of patients with suspected acute cholecystitis are reviewed in detail...

CASE: Introduction:Fecal calprotectin is a known inflammatory marker used to evaluate patients with Inflammatory Bowel Disease (IBD). In fact, ACG Clinical Guideline for management of Crohn's disease recommend fecal calprotectin (FC) as a helpful test to distinguish IBD versus functional disorder such as Irritable Bowel Syndrome. Studies have also shown association of fecal calprotectin with colon cancer. Recent study proposed fecal calprotectin could be a reliable marker for ruling out organic disease with high negative predictive value...

INTRODUCTION AND IMPORTANCE: Appendiceal neuroendocrine tumors (ANETs) are incidentally found in 0.2-0.7% of appendectomies for suspected appendicitis. CASE PRESENTATION: A 29-year-old female presented with pain in the right lower quadrant of her abdomen for the past 48 h. On emergency appendectomy for suspected acute appendicitis, a perforated appendix was found. Histopathological examination showed grade 1 (low) ANET. CLINICAL DISCUSSION: Appendiceal neuroendocrine neoplasms (ANENs) are commonly found at the tip of the appendix and are treated with appendectomy alone...

BACKGROUND: Postpartum ovarian thrombosis is an uncommon condition. It appears with the nonspecific, predominantly right-sided abdominal symptoms and must be differentiated from other acute visceral conditions. If left untreated, postpartum ovarian thrombosis can have severe consequences, including sepsis, pulmonary embolism, and even death. Momentarily, there are no specific guidelines for postpartum ovarian thrombosis management. We present a case of postpartum ovarian thrombosis admitted to our hospital with symptoms of acute appendicitis...
