Successful endoscopic management of a persistent bronchobiliary fistula with Histoacryl®/Lipiodol® mixture.

Introduction A bronchobiliary fistula (BBF) following liver directed therapy (resection/ablation) is a rare complication in which an abnormal communication between the biliary tract and bronchial tree is formed. This case report describes the successful management of a persistent BBF following multiple liver wedge resections and microwave ablation in a patient with a metastatic neuroendocrine tumour of the terminal ileum. Case history A 69-year-old man presented with unexplained weight loss and was subsequently diagnosed with a neuroendocrine tumour of the terminal ileum and liver metastasis. Following elective right hemicolectomy and multiple bilobar liver wedge resections combined with liver microwave ablation, he developed an early bile leak. A month later, a right subphrenic collection was identified and four months following surgery, biloptysis was noted. Numerous attempts with endoscopic retrograde biliary drainage (ERBD) failed to achieve sufficient drainage. The patient was treated successfully with endoscopic injection of a mixture of Histoacryl® glue (B Braun, Sheffield, UK) and Lipiodol® (Guerbet, Solihull, UK). There was no evidence of the BBF one year following intervention. Conclusions This novel approach for persistent BBF management using endoscopic Histoacryl® glue embolisation of the fistula tract should be considered either as an adjunct to ERBD or when biliary tract decompression by drainage and/or sphincterotomy fails, prior to proceeding with surgical interventions.

Solid pseudopapillary neoplasm of the pancreas: Management and long-term outcome.

BACKGROUND: Solid pseudopapillary neoplasm (SPN) of pancreas is a rare pancreatic neoplasm with a low metastatic potential. Our aim was to study the clinical-pathological characteristics, and long-term outcome of this tumor. MATERIALS: Rretrospective single center study of patients operated for SPN of pancreas. Clinical and pathological data were collected. RESULTS: From 1995 to 2016, 1320 patients underwent pancreatic resection. SPN was confirmed in 32 cases (2.46%), including 29 (90.6%) female and three (9.4%) male, with a mean age of 28.4 ± 12.2 years. SPN was the most common pathology among female patients under age of 40 (72.4%). Abdominal pain was the most frequent presenting symptom (48%), whereas none of the patients presented with jaundice. Mean tumor diameter was 5.9 cm (range, 0.9-14 cm). All patients underwent margin-negative surgical resection. Two patients demonstrated gross malignant features, including liver metastases at presentation (n = 1), and adjacent organ and vascular invasion (n = 1). Microscopic malignant features were present in thirteen patients (40.6%). Recurrence occurred in the retroperitoneal lymph nodes (n = 1, 7 years post resection) and in the liver (n = 2, 1 and 5 years post resection). Mean follow-up was 49.2 months (range, 1-228 months). Five and 10-year disease-free survival was 96.5% and 89.6% respectively. CONCLUSIONS: SPNs are low-grade tumors with a good prognosis. Margin-negative surgical resection is curative in most patients. However, almost 15% of patients demonstrate malignant features including invasion of adjacent organs or metastatic disease. Patients with malignant disease are still expected to have long survival, and aggressive surgical approach is advocated.
