Severe Intra-abdominal Infection due to Streptococcus Milleri Following Adjustable Gastric Banding

Abstract

Laparoscopic adjustable gastric banding represents a safe and effective bariatric surgical method. Nevertheless, complications such as intraabdominal infections are associated with high morbidity and mortality. A 50-year old morbidly obese female patient underwent adjustable gastric banding with the Swedish band (SAGB). After an uneventful postoperative follow-up of 2 years, she developed band infection due to colon microperforation during endoscopic polypectomy. As the causative microorgansim, Streptococcus Milleri was revealed. Band removal was required, and recovery was quite prolonged. Intra-abdominal infection with Streptococcus Milleri can cause severe and life-threatening disease. Therefore, early diagnosis and surgical intervention combined with body weight adapted antibiotic therapy for a sufficiently long period of time seems necessary. In patients with intra-abdominal implanted devices such as the SAGB who undergo endoscopic polypectomy, antibiotic prophylaxis should therefore be considered.
