Unveiling Uncommon: Perforated Peptic Ulcer Mimicking Post-Cesarean Complications—A Case Report

<b>Background and Clinical Significance</b>: Peptic ulcer perforation is a severe complication of peptic ulcer disease, resulting from erosion of the upper gastrointestinal mucosa. While uncommon in post-cesarean patients, its symptoms can resemble post-operative complications, risking delayed diagnosis and adverse outcomes. This case highlights the need for an expanded diagnostic approach in post-cesarean patients with atypical abdominal symptoms. <b>Case Presentation</b>: A 27-year-old West African woman presented to Ain Shams University Hospital in Cairo, Egypt, with worsening abdominal pain, vomiting, fever, and tachycardia three weeks post-cesarean. Initially misdiagnosed with gastroenteritis, she underwent emergency laparotomy due to persistent symptoms, which revealed a 3 cm perforated peptic ulcer. An omental patch repair was performed, and she was discharged in stable condition seven days later. Peptic ulcer perforation, although rare post-cesarean, can mimic common post-operative symptoms, leading to diagnostic delays. A thorough evaluation of abdominal symptoms unresponsive to standard post-operative care is essential, as misdiagnosis increases risks of morbidity. Non-gynecologic causes should be considered, particularly with persistent symptoms. <b>Conclusions</b>: Physicians should consider peptic ulcer perforation in post-cesarean patients presenting with sustained abdominal pain, fever, or gastrointestinal distress. Recognizing atypical complications early allows timely intervention, improving outcomes and reducing mortality. This case underscores the value of broad differential diagnoses in post-operative care.
