Endoscopic retrograde cholangiopancreatography (ERCP)-related esophageal perforation in osteogenesis imperfecta

A 77-year-old woman with osteogenesis imperfecta was admitted with symptomatic choledocholithiasis. Endoscopic retrograde cholangiopancreatography (ERCP) was carried out and mild resistance was encountered in the distal esophagus with “red out” during intubation. The duodenoscope was withdrawn and gastroscopy revealed a tear in the distal esophagus ([Fig. 1]). As a perforation was suspected, a nasogastric tube was deployed, intravenous antibiotics were started, and surgery was consulted. An esophagogram confirmed the esophageal leak ([Fig. 2]) and thoraco-abdominal computed tomography (CT) showed a 0.7-cm esophageal perforation and air–fluid collection (3 cm × 10 cm) in the posterior mediastinum ([Fig. 3]). Conservative management was decided on due to clinical stability and poor operative candidacy. Within 48 hours the liver function tests normalized and parenteral nutrition was started. The day 7 esophagogram showed partial healing. Enteral feeding was started with a nasojejunal tube placed fluoroscopically. An esophagogram on day 27 showed complete healing ([Fig. 4]). The patient started an oral diet and was discharged with plan for elective cholecystectomy.

Osteogenesis imperfecta is an autosomal dominant disorder of collagen synthesis (1 in 10 000 births). Gastrointestinal manifestations in osteogenesis imperfecta are rare although spontaneous colon perforation has been reported, where histopathological examination showed absence of muscle layers in the perforated segment [1]. Murine models of osteogenesis imperfecta showed thinner esophageal submucosa and muscularis compared with wild mice [2]. ERCP-related perforations are infrequent (0.4 %) and are commonly related to improper guidewire insertion or sphincterotomy [3]. Esophageal perforation in ERCP is rare and is attributed to use of sharp accessories [3] [4]. This is the first reported case of esophageal perforation in osteogenesis imperfecta. We believe that perforation in our patient occurred due to abnormal esophageal submucosa and muscularis and limited view with duodenoscope. Esophageal perforations are traditionally managed surgically; however, good outcomes are reported with conservative management in smaller perforations and contained leaks [5]. The present case highlights the propensity for esophageal perforation in osteogenesis imperfecta. We recommend caution and low threshold to suspect perforation during gastrointestinal endoscopy in osteogenesis imperfecta.
