Complicated diverticulitis: Diagnostic precision and surgical solutions in a patient with chronic kidney disease.

Diverticulitis, an inflammation of diverticula in the colon, can lead to severe complications such as perforation and abscess formation. A 42-year-old female with polycystic kidney disease and chronic kidney disease stage III presented with severe abdominal pain, fever, and inability to tolerate oral intake. The patient was a previous smoker who smoked 0.5 packs per day for 25 years. Initial evaluation revealed leukocytosis and elevated creatinine. A CT scan identified pneumoperitoneum and mild sigmoid diverticulitis, suggesting a perforated viscus. She underwent urgent exploratory laparotomy, which confirmed the CT findings and resulted in an appendectomy, sigmoid colon resection, and ostomy creation. Postoperatively, the patient faced complications, including recurrent pneumoperitoneum and subcutaneous emphysema, detected through follow-up CT scans, leading to further surgical interventions. CT imaging was pivotal in diagnosing, monitoring, and guiding treatment, with noncontrast CT being beneficial given her renal impairment. Early diagnosis and CT imaging are crucial in managing complicated diverticulitis. Postoperative monitoring with CT scans is essential for detecting complications. Follow-up care should include regular colonoscopies to assess diverticular disease and dietary modifications to prevent recurrence. Combining clinical, surgical, and radiologic data ensures effective management and improves patient outcomes.
