- Traumatic neuroma (TN), also known as amputation neuroma, is a reactive hyperplasia of nerve fibers and connective tissue arising from Schwann cells after trauma or surgery. TN of the bile duct is usually asymptomatic, but rarely can lead to right upper quadrant pain, biliary obstruction, and acute cholangitis. It is very difficult to discriminate TN from malignancy before surgery, although doing so could avoid an unnecessary radical resection of the lesion. In the course of surgery, TN can be caused by unintentional injury of a nerve fiber near the common bile duct (CBD) and heat damage to an artery, complete ligation of an artery, and excessive manipulation of the CBD. Therefore, to prevent TN after cholecystectomy, surgery should be performed carefully with appropriate consideration of anatomic variations, and a cystic duct should not be resected too close to the CBD. The possibility of TN should be considered if a patient who has undergone CBD resection with hepaticojejunostomy or cholecystectomy long ago experiences symptoms of jaundice, cholangitis, or obliteration of the CBD. In this report, we present a case of TN mimicking cholangiocarcinoma that emerged from a cystic duct stump after cholecystectomy.

Objectives
Postoperative opioid use and pain are related to postoperative delirium. This study aims to compare the incidence of delirium in patients with and without patient-controlled intravenous analgesia (PCIA) among liver transplant recipients.
Methods
The medical records of 253 patients who received liver transplantation (LT) from January 2010 to July 2017 in a single university hospital were retrospectively reviewed. Patients were divided into two groups: the patients who had used PCIA (P group, n = 71) and those who did not use PCIA (C group, n = 182) after LT in intensive care unit (ICU). The patient data were collected, which included demographic data, and details about perioperative management and postoperative complications.
Results
There was no difference in the model for end-stage liver disease (MELD) score between the two groups. Postoperative delirium occurred in 10 / 71 (14.08 %) in the P group and 26 / 182 (14.29 %) in the C group after LT, respectively (P = 0.97). After propensity score matching, no differences were observed in the incidence of delirium (P = 0.359) and the time from surgery to discharge (P = 0.26) between the two groups.
Conclusions
Patients with PCIA after LT exhibited no relationship with postoperative delirium. Therefore, it is necessary to actively control postoperative pain using PCIA.
