Treatment of delayed pancreatic fistula associated with anastomosis breakdown after pancreaticoduodenectomy using percutaneous interventions.

We here present a rare case of development of a postoperative pancreatic fistula and breakdown of the pancreaticojejunal anastomosis 8 months after pancreaticoduodenectomy. A 70-year-old man underwent pancreaticoduodenectomy for distal cholangiocarcinoma and initially recovered well. However, 8 months later, he developed abdominal pain and distention and was admitted to our institution with suspected pancreatitis. On the 17th day of hospitalization, he suddenly bled from the jejunal loop and a fluid collection was detected near the pancreaticojejunal anastomosis site. The fluid collection was drained percutaneously. Subsequent fistulography confirmed breakdown of the pancreaticojejunal anastomosis. Considering the patient's overall condition and the presence of postoperative adhesions, we decided to manage him conservatively. An additional drain tube was placed percutaneously from the site of the anastomotic breakdown into the lumen of the jejunum, along with the tube draining the fluid collection, creating a completely new fistula. This facilitated the flow of pancreatic fluid into the jejunum and was removed 192 days after placement. During a 6-month follow-up, there were no recurrences of pancreatitis or a pancreatic fistula. This case highlights the efficacy of percutaneous drainage and creation of an internal fistula as a management strategy for delayed pancreatic fistula and anastomotic breakdown following pancreaticoduodenectomy.

[Successful treatment of a fulminant-type Wilson's disease with deceased donor liver transplantation after recovery from critical illness].

A 15-year-old female patient was diagnosed with a fulminant-type Wilson's disease. She had severe illness with a Model for End-Stage Liver Disease score of 25 and new Wilson Index score of 11. She underwent plasma exchanges, hemodiafiltration, and administration of fresh frozen plasma on consecutive days. Finally, she had recovered from severe illness and was discharged from the hospital. After 18 months of waiting time, she underwent deceased liver transplantation and returned to normal daily life. In Japan, the critical shortage of donated organs requires a long waiting time. Previous studies demonstrated that artificial liver support systems, including plasma exchange and hemodiafiltration, could be useful for a fulminant-type Wilson's disease. For such a disease, multidisciplinary bridging treatments are crucial for a successful liver transplantation.

Portal Annular Pancreas With Common Hepatic Artery Trajectory Abnormality: A Case Report and Review of the Literature.

ABSTRACT: Portal annular pancreas (PAP) is a rare congenital pancreatic anomaly, in which the uncinate process of the pancreas fuses to the body of pancreas behind the portal vein. Here, we report a case of PAP with common hepatic arterial anomaly, which was identified during surgery. A 57-year-old man who had branch type intraductal papillary mucinous neoplasm in the head of the pancreas developed a nodule in the cystic lesion. We planned pylorus preserving pancreaticoduodenectomy. The common hepatic artery from the celiac artery passing behind the portal vein was revealed in preoperative examinations. During surgery, we discovered that the uncinate process of the pancreas was fused with the body of the pancreas behind the portal vein. We divided the pancreas at the anterior and posterior of the portal vein. The main pancreatic duct was present in the anterior pancreatic stump. We performed pancreaticojejunostomy in the anterior stump and closed the posterior stump by interrupted suture. Forty-four surgical cases of PAP have been reported in the English medical literature. There are few previous reports of PAP which involved an arterial anomaly. Clinicians should consider PAP preoperatively to ensure that the surgeon can appropriately plan pancreatic resection to avoid postoperative complications.
