Primary epiploic appendagitis is uncommon and is estimated to induce 1.1–1.3% of all abdominal pain. We report a 42-year-old male who appeared in the morning in the emergency department with abdominal pain localized in the right lower abdomen and associated with anorexia and nausea. Clinical examination, laboratory tests, and abdominal ultrasound revealed deep tenderness at Mc Burney point and a mild elevation of CRP (0.7 mg/dL). In the evening, the symptoms were exacerbated, and a diagnostic laparoscopy was performed. Intra-operatively, the appendix was normal and a twisted, necrotic epiploic appendage originating from the antimesenteric border of the mid ascending colon was found. Laparoscopic resection of the necrotic epiploic appendage and prophylactic appendectomy was carried out. Histology indicated the diagnosis of the necrotic epiploic appendage. Postoperatively, the patient recovered without complications. Although the preoperative diagnosis of primary epiploic appendagitis has improved due to abdominal ultrasound and mainly CT, there are still cases which are diagnosed during laparoscopy. The treatment of choice is conservative management, while the use of antibiotics remains controversial. The relapse and complication rates are rare. Surgical excision, particularly laparoscopic, should be considered in cases of uncertain diagnosis, persistent symptoms, or recurrence. (Korean J Gastroenterol 2020;76:88-93)
