EGS SO28 - Management of oesophageal diverticulitis in a 71-year-old female: Case report and review of management approaches

Abstract Background Oesophageal diverticulitis is a rare condition with fewer than ten reports in the literature. We present a case of oesophageal diverticulitis in a 71-year-old female with a history of COPD, TIA, and known oesophageal diverticulum. She was managed conservatively with NBM, total parenteral nutrition and intravenous antibiotics requiring a 16-day inpatient stay. The rarity of this condition poses challenges in its diagnosis and management, necessitating a thorough understanding of both conservative and surgical interventions. This case highlights the complexity involved in treating oesophageal diverticulitis, especially in patients with significant comorbidities. Method Patient presented with a 6-day history of upper abdominal pain and sepsis (elevated inflammatory markers; CRP 320, WCC 11.1, temperature 38.0, pulse 104). Abdomen was soft with upper abdominal tenderness. Imaging was consistent with diverticulitis of a 5.9cm lower oesophageal diverticulum without perforation. Initial management included making the patient nil by mouth, total parenteral nutrition, and intravenous antibiotics (vancomycin and metronidazole). The patient’s condition was closely monitored with serial blood tests and clinical assessments. Opinion was sought from a tertiary upper GI centre. Discharge was planned once the patient safely transitioned to oral diet and was apyrexial for 48 hours. Results Inflammatory markers improved over five days (CRP from 320 to 51, WCC from 11.1 to 9). She remained intermittently pyrexial until day 8 of admission. Clinical improvement allowed transition from intravenous to oral therapy, and she was discharged on day 16 with double dose oral PPI therapy. Patient has been followed up by tertiary upper GI services with plans for consideration of surgical resection of the oesophageal diverticulum. The patient’s successful discharge without surgical intervention during the acute phase underscores the effectiveness of a conservative management approach initially, with a plan for definitive surgical treatment in a stable outpatient setting. Conclusion Oesophageal diverticulitis, though rare, requires a nuanced approach to management, especially in patients with significant comorbidities. This case demonstrates the importance of an awareness of thorough history taking and review of previous examinations to prevent delayed diagnosis of a rare pathology not demonstrated on a CT abdomen and pelvis. This approach highlights the importance of individualised treatment plans and the potential for conservative management to provide stabilisation, followed by elective surgical management. The paucity of cases of oesophageal diverticulitis has prevented development of evidence based guidelines, underscoring the importance of seeking advice from tertiary centers when managing rare presentations.
