0 The authors report on a 7-year-old boy who sustained blunt abdominal trauma on a bicycle handlebar. A large traumatic pancreatic pseudocyst developed, for which percutaneous external drainage under ultrasound guidance was performed. Both the catheter fistulogram and endoscopic retrograde cholangiopancreatogram showed complete disruption of the main pancreatic duct. During continuous external drainage, the pseudocyst disappeared. The drainage flow decreased gradually and ceased. The patient is well, with normal endocrine and exocrine pancreatic functions, 2 years after discharge. Copyright o 1995 by W. B.

ERCUTANEOUS external drainage (PED) is one of the therapeutic procedures for traumatic pancreatic pseudocyst. la2PED may facilitate the resolution of a pseudyocyst and shorten the hospital stay. Even in an emergency patient with impending risk, PED can be performed easily, with minimal complication. In this report the authors describe a case of complete disruption of the main pancreatic duct successfully managed by PED.

CASE REPORT A 7-year-old boy was admitted to another hospital after sustaining blunt abdominal trauma from a bicycle handlebar. Upper abdominal pain and hyperamylasemia were suggestive of pancreatic injury. On day 1, ultrasound examination showed fluid collection in the body of the pancreas. Despite conservative treatment consisting of complete bowel rest with nasogastric suction and hyperalimentation, the pseudocyst increased in size. On day 51, PED was applied under ultrasound guidance. Because the drainage was poor, he was transferred to Fukuoka Children’s Hospital for further treatment, on day 62. At the time of admission, he complained of abdominal pain, and showed vomiting and a high fever. Catheter fistulogram did not show any specific findings, but diagnostic modalities showed a large pseudocyst measuring 11 cm in diameter (Fig 1). The drainage was confirmed to be ineffective, and additional PED through another route was applied on day 70. All the symptoms disappeared after this procedure was begun. The drainage flow was as high as 447 mL per day under subsequent conservative treatment. During management, both serial catheter fistulograms and endoscopic retrograde cholangiopancreatogram (ERCP) showed abrupt disruption of the pancreatic duct (Fig 2). Although we recommended operative options to the patient’s parents, they expressed a strong desire that the PED be continued because the patient was otherwise healthy.

Oral intake was started on day 105, and the drainage flow ceased on day 139. The drainage catheter was removed on day 161, and he was discharged on day 200. Although routine ultrasonography showed slight dilatation of the distal pancreatic duct, the boy remains asymptomatic, with normal growth. Follow-up ERCP has not been conducted because

DISCUSSION
Traumatic pancreatic pseudocyst is a rather severe sequela of pancreatic injury in children. Because it often resolves spontaneously, the conditions and timing of surgical intervention remain controversial. PED is currently used with increasing frequency for pancreatic pseudocyst, even in children.3,4 However, there is widespread belief that the procedure cannot be applied if there is a complete ductal disruption without proximal drainage.s Early laparotomy has been advocated because of the concern of PED failure. However, we showed the effectiveness of PED even in a patient with complete disruption of the main pancreatic duct. With respect to the use of PED, the two points to be emphasized are that the original drainage catheter should be placed through a confirmed access route under ultrasound guidance and that the drainage catheter should always be positioned in the optimal drainage site under serial follow-up fistulograms. Proper catheter placement not only accelerates the drainage effect but also minimizes the risk of inappropriate ductal obstruction relating to compression of the catheter itself. Amelioration of the inflammatory process would promote recanalization of the major ductal system in children. To our knowledge, this is the first report of major ductal disruption successfully managed by PED. The observations in this case may extend the indications for PED in the treatment of traumatic pancreatic pseudocyst in children. REFERENCES 1.
