Epiploic appendagitis (EA) is a rare cause of acute abdominal pain caused by inflammation of an epiploic appendage. It has a nonspecific clinical presentation that may mimic other acute abdominal pathologies on physical exam, such as appendicitis, diverticulitis, or cholecystitis. However, EA is usually benign and self-limiting and can be treated conservatively. We present the case of a patient with two episodes of EA, the first mimicking acute appendicitis and the second mimicking acute cholecystitis. Although recurrence of EA is rare, it should be part of the differential diagnosis of acute, localized abdominal pain. A correct diagnosis of EA will prevent unnecessary hospitalization, antibiotic use, and surgical procedures.

Endogenous peritonitis resulting from inflammation or perforation of an abdominal viscus-a result, for example, of diverticulitis, cholecystitis, or acute appendicitis-can be a complication in patients undergoing peritoneal dialysis (PD), with significant morbidity and a high incidence of catheter loss.Here, we describe an end-stage renal disease patient on PD who presented with acute abdominal pain and who was diagnosed with uncomplicated PD peritonitis. His clinical course was complicated by development of eosinophilic peritonitis because of an allergy to vancomycin. Subsequently, when he failed to show clinical improvement, abdominal and pelvic imaging revealed severe appendicitis, which necessitated emergent surgical intervention.

Omental infarction is a rare cause of acute abdominal pain. Without the support of radiological evidence, diagnosis is difficult to attain owing to its infrequent incidence, low awareness among clinicians, and its nonspecific presentation that mimics other causes of acute abdomen, namely, acute appendicitis and cholecystitis. Incorrect diagnosis may lead to unnecessary invasive surgery in patients with omental infarction, a disorder that is typically managed conservatively without exposing the patient to intraoperative risks and postoperative morbidity. We report a case of a 61-year-old man who presented to the emergency department with signs of peritonitis. He was eventually diagnosed with omental infarction through computed tomography of the abdomen. He was successfully managed medically with nonsteroidal anti-inflammatory and antiemetic medications, with complete resolution of his symptoms within 2 weeks.

Omental infarction is an uncommon cause of acute abdomen but one that clinically mimics more serious and common causes of acute abdomen like appendicitis and cholecystitis. Historically, it was diagnosed only intraoperatively during surgery for presumed appendicitis or other causes of acute abdomen. But with the increase in the use of imaging, especially abdominal computed tomography (CT) scan in the work-up for acute abdomen, more cases of omental infarction are being diagnosed preoperatively. This has also led to the observation that omental infarction is a self-limiting condition which can be managed conservatively. Currently, conservative management and surgery are the only treatment options for omental infarction with no consensus as to the best treatment modality. Having a patient with both acute appendicitis and omental infarction simultaneously is extremely rare with only two reported cases in the literature thus far. Here, we present a 10-year-old obese female who presented to our hospital with acute abdomen and was found to have acute appendicitis and omental infarction. The patient underwent laparoscopic appendectomy and resection of the infarcted omentum and had uneventful recovery and was discharged on the second postoperative day. In this report, we present a review of current literature on omental infarction and highlight the importance of imaging especially abdominal CT scan in the nonoperative diagnosis and treatment of omental infarction.

Acute appendicitis and acute cholecystitis are some of the most common surgical emergencies in the emergency department. Both conditions are common causes of abdominal pain. We had a discussion about co-existing acute appendicitis and cholecystitis and if it is a myth. The concurrent presentation of acute appendicitis and cholecystitis is thought to be rare. A PubMed search of MEDLINE was performed using a combination of the keywords "acute appendicitis" and "acute cholecystitis" to obtain case reports. The search returned 11 case reports of co-existent acute appendicitis and acute cholecystitis. The aim of this review is to broaden the prospective of emergency physicians to consider more than one pathology as the cause of abdominal pain. The concurrent presentation of acute appendicitis and cholecystitis is rare but should be considered to avoid complications such as perforation and septicemia.

Primary epiploic appendagitis (PEA) is a rare and frequently underdiagnosed cause of acute abdominal pain. PEA most commonly affects obese, male patients in the 4th and 5th decade of life. Clinical presentation includes acute, localized, non-migrating pain without fever, nausea, vomiting or diarrhea and the laboratory workup is usually within normal limits. PEA is commonly mistaken as other more severe causes of acute abdominal pain, such as diverticulitis, acute appendicitis or cholecystitis and thus patients undergo unnecessary diagnostic and therapeutic procedures. The emergence of computerized tomography (CT) as the gold standard imaging test in diagnostic dilemmas of acute abdominal pain has resulted in increased recognition and diagnosis of PEA. Upon confirmation, PEA is considered a self-limiting disease and is managed conservatively with analgesics, occasionally combined with nonsteroidal anti-inflammatory drugs (NSAIDS). Persistence of symptoms or recurrence mandate the consideration of surgical management with laparoscopic appendage excision as the definitive treatment. We review the current literature of PEA, with a focus on clinical and imaging findings, in order to raise awareness about this frequently misdiagnosed entity.

In December 2019, in Wuhan, China, the first cases of what would be known as COVID-19, a disease caused by an RNA virus called SARS-CoV-2, were described. Its spread was rapid and wide, leading the World Health Organization to declare a pandemic in March 2020. The disease has distinct clinical presentations, from asymptomatic to critical cases, with high lethality. Parallel to this, patients with non-traumatic surgical emergencies, such as acute appendicitis and cholecystitis, continue to be treated at the emergency services. In this regard, there were several doubts on how to approach these cases, among them: how to quickly identify the patient with COVID-19, what is the impact of the abdominal surgical disease and its treatment on the evolution of patients with COVID-19, in addition to the discussion about the role of the non-operative treatment for abdominal disease under these circumstances. In this review, we discuss these problems based on the available evidence.

A 26-year-old male patient with no significant past history presented with a two-day illness of nausea and abdominal pain, mimicking acute appendicitis. The appendix was poorly visualized on the ultrasound scan so a CT scan was done which revealed infarction of the omentum on the right side of the abdomen. The patient was closely monitored and managed conservatively with analgesics, fluids and antibiotics. Spontaneous improvement occurred in a day, and oral feeding was resumed. The clinical course was uncomplicated, and the patient was discharged, circumventing unnecessary surgery. Literature search has revealed that omental infarction is a rare cause of acute abdomen and it can mimic acute appendicitis or cholecystitis. The treatment needs to be individualized, and surgery may or may not be required.
