Gastrosplenic Fistula and/or Splenic Abscess: A Rare and Refractory Complication Following Sleeve Gastrectomy.

ABSTRACT

Splenic abscess is a rare complication often associated with sleeve gastrectomy (SG) due to factors including local infections, distant infections, tumors, ischemia, and trauma, which presents substantial challenges. We report four cases of gastrosplenic fistula and/or splenic abscess after SG. Patient data, including demographics, comorbidities, diagnostic procedures, treatments, and outcomes, were recorded. Surgical techniques for SG adhered to established protocols. Four patients had a male-to-female ratio of 22, with an average age of 39.8 years and an average preoperative BMI of 38.9 kg/m2. All patients were readmitted due to recurrent fever and chills caused by splenic abscesses detected on CT scans, with an average admission duration of 16.5 weeks. Treatments varied from fasting and antibiotics to percutaneous drainage and surgical interventions. The average treatment duration post-diagnosis of splenic abscess was 37.25 weeks. Managing gastrosplenic fistula and/or splenic abscess is complex, underscoring the significance of prompt diagnosis and proper treatment. This highlights the need for heightened awareness among healthcare professionals to promptly recognize and manage this rare complication after SG.
