Refractory pediatric nonrhabdomyosarcoma soft tissue sarcoma associated with ectopic production of beta hCG and hypercalcemia induced by PTHrP.

A 3-month-old male with a mass on the right side of his back was admitted to our hospital. The tumor was a pathologically high-grade nonrhabdomyosarcoma soft tissue sarcoma (NRSTS). Treatment included subtotal tumor resection followed by chemotherapy.

Pancreatobiliary reflux and the length of a common channel.

Background/purpose: Gallbladder cancer occurs frequently in patients with pancreaticobiliary maljunction due to pancreatobiliary reflux. Pancreatobiliary reflux is also detected in some patients with a relatively long common channel. This study aimed to clarify the correlation between pancreatobiliary reflux and the length of a common channel.

Successful preemptive surgical division of type 2-congenital extrahepatic portosystemic shunt in children.

Purpose: A congenital extrahepatic portosystemic shunt (CEPS) is a rare abnormality. The shunts are classified into 2 types. Of these, a type 2-shunt is a side-to-side one, which may be treated by a simple shunt division.

Laparoscopic strategy for inguinal ovarian hernias in children: when to operate for irreducible ovary.

Background: Sliding indirect inguinal hernias containing the ovary and fallopian tube are not uncommon in younger girls. Although an irreducible ovary is not at great risk of incarceration, this condition may become a significant risk factor for torsion or strangulation. This paper describes the indications for surgery in children with irreducible ovaries.

Laparoscopic percutaneous extraperitoneal closure for inguinal hernia in children: clinical outcome of 972 repairs done in 3 pediatric surgical institutions.

Background/purpose: In 1995, we developed laparoscopic percutaneous extraperitoneal closure (LPEC) to treat inguinal hernias in children. This study evaluated LPEC's safety, efficacy, and reliability in 3 hospitals.

Methods: In 2 hospitals, LPEC was the standard procedure used to repair inguinal hernias in children, and in 1 hospital, it was done optionally in girls.

Is acetylcholinesterase activity in neorectum after laparoscopic endorectal pull-through method for Hirschsprung's disease a primary or a secondary condition?

Between 1996 and 2002, 22 cases of Hirschsprung's disease were treated laparoscopically by endorectal pull-through operation. The proximal margin of the resected bowel materials from these 22 patients were examined histologically by frozen sections at surgery and also after surgery using H&E staining, and complete resection of the aganglionic segment was confirmed. Eleven patients, in whom an informed consent was obtained at randomly, underwent suction biopsy from the pulled-though neorectum after surgery.

No incidence of port-site recurrence after endosurgical procedure for pediatric malignancies.

Port-site recurrence (PSR) following laparoscopic procedures has been an unpredictable complication in adult cancer patients; however, no data exist about this phenomenon in the pediatric field. The aim of this study was to determine whether PSR, following endosurgical procedure for malignancies, is a typical complication or a rare event in the pediatric population. Eighty-one questionnaires were mailed to members of The Japanese Society of Pediatric Endosurgeons.
