[Acute abdomen due to rupture of mesenteric cysts. Observations on a clinical case and review of the literature]

Abstract

Personal experience based on a clinical case of a young woman with acute abdominal pain referable to acute appendicitis is presented. The surgical procedure was performed through a Mc Burney incision and revealed the rupture of mesenteric cysts; removal of the cysts was carried out without intestinal resection. Post-operative course was uneventful and 2 years follow-up showed no recurrence. Mesenteric cysts are an uncommon pathology, mainly in adult ages. After an analysis of the incidence and etiology, the pathological features and types of clinical presentation are discussed. Diagnosis in asymptomatic cases is usually made in search of other diseases. Complications are rare: rupture, infection and intestinal obstruction. In such cases, the clinical presentation is usually attributable to the main causes of acute abdomen, unless ultrasonography or CT scan are performed. When mesenteric cyst is diagnosed, a laparoscopic approach should be performed, even if in emergency traditional surgery is justified. Total excision of the cyst is necessary to avoid recurrence and obtain a correct pathologic evaluation.
