Liver Transplantation from Female Donors Provokes Higher Complement Component C5a Activity.

Background: Transplanted organs from female donors are associated with less favorable prognoses and outcomes. This study aimed to determine whether donor gender affects levels of serum terminal complement component C5a and oxidative stress in pediatric living related liver transplantation (LRLTx) recipients.

Material/methods: The subjects were 43 patients (20 males and 23 females) who underwent LRLTx during childhood (age range 1.

Laparoscopic sigmoidectomy combined with uterus excision for colouterine fistula caused by sigmoid colon diverticulitis: A case report.

A case of colouterine fistula caused by colonic diverticulitis that was successfully treated laparoscopically is presented. A 74-year-old woman visited us with lower abdominal discomfort and vaginal excretion with minor fecal contamination. Mild tenderness was observed in her lower abdomen.

Pure laparoscopic hepatectomy as repeat surgery and repeat hepatectomy.

Aim: To assess clinical outcomes of laparoscopic hepatectomy (LH) in patients with a history of upper abdominal surgery and repeat hepatectomy.

Methods: This study compared the perioperative courses of patients receiving LH at our institution that had or had not previously undergone upper abdominal surgery. Of the 80 patients who underwent LH, 22 had prior abdominal surgeries, including hepatectomy (n = 12), pancreatectomy (n = 3), cholecystectomy and common bile duct excision (n = 1), splenectomy (n = 1), total gastrectomy (n = 1), colectomy with the involvement of transverse colon (n = 3), and extended hysterectomy with extensive lymph-node dissection up to the upper abdomen (n = 1).

X-ray diagnosis with a bloating agent for foreign object ingestion.

The location of an ingested foreign object is often difficult to determine by X-ray if gastric air bubbles are not clear in the image. Methods that provide negative contrast can facilitate precise object localization, which is important for object retrieval and treatment of the patient. This case report describes a male child, 2 years and 2 mo of age, who accidentally swallowed a lithium battery while playing at home.

Pure laparoscopic hepatectomy for hepatocellular carcinoma with chronic liver disease.

Pure laparoscopic hepatectomy is a less invasive procedure than conventional open hepatectomy for the resection of hepatic lesions. Increases in experiences with the technique, in combination with advances in technology, have promoted the popularity of pure laparoscopic hepatectomy. However, indications for usage and potential contraindications of the procedure remain unresolved.

Caudal approach to pure laparoscopic posterior sectionectomy under the laparoscopy-specific view.

Aim: To study our novel caudal approach laparoscopic posterior-sectionectomy with parenchymal transection prior to mobilization under laparoscopy-specific view.

Methods: Points of the procedure are: (1) Patients are put in left lateral position and posterior sector is not mobilized; (2) Glissonian pedicle of the sector is encircled and clamped extra-hepatically and divided afterward during the transection; (3) Dissection of inferior vena cava (IVC) anterior wall behind the liver is started from caudal. Simultaneously, liver transection is performed to search right hepatic vein (RHV) from caudal; (4) Liver transection proceeds to the bifurcation of the vessels from caudal to cranial, exposing the surfaces of IVC and RHV.

Children undergoing liver transplantation for treatment of inherited metabolic diseases are prone to higher oxidative stress, complement activity and transforming growth factor-β1.

Background: Main indications for liver transplantation in the pediatric population include biliary atresia and inherited metabolic diseases. The present study evaluated whether there are differences between pediatric patients undergoing living-related liver transplantation due to the two diseases in terms of their oxidative and immunological status during their regular outpatient follow-up visits.

Material And Methods: A clinical outpatient study measuring serum oxidative stress index (calculated as serum oxidant/antioxidant ratio, in the form of serum total hydroperoxide/serum biological antioxidative potential), serum terminal complement component 5a, as an indicator of complement activity and immunological status, and transforming growth factor-ß1, as a marker of liver fibrosis, in 16 patients (6 males and 10 females, 2.

A case of solitary necrotic nodule treated with laparoscopic hepatectomy: spontaneous regression of hepatocellular carcinoma?

Solitary necrotic nodule of the liver is a rare benign lesion with a completely necrotic core and a hyalinized fibrotic capsule containing elastic fibers. The pathogenetic mechanism is still unclear. We here describe a case of SNN, whose central reticulin fibers within the nodule suggest the origin as hepatocellular carcinoma or other hepatocyte-origin tumors, treated with laparoscopic anatomical segmentectomy of the liver.

Pediatric patients receiving ABO-incompatible living related liver transplantation exhibit higher serum transforming growth factor-β1, interferon-γ and interleukin-2 levels.

Background: ABO-incompatible liver transplantation (LTx) is becoming more common in response to the paucity of liver allografts. Several studies have expressed concern about the effect of ABO compatibility on graft survival.

Purpose: To evaluate the differences in serum cytokine levels between ABO-incompatible (ABO-i) and ABO-compatible (ABO-c; includes ABO-compatible and identical) pediatric LTx recipients during regular outpatient follow-up.

Oxidative stress after living related liver transplantation subsides with time in pediatric patients.

Background: Oxidative stress has been suspected to influence graft survival and prognosis in pediatric recipients of living related liver transplantation (LRLT).

Purpose: We determined the oxidative status of pediatric LRLT recipients during their regular outpatient follow-up visits, and looked for a relationship between oxidative status and post-liver transplantation (post-LTx) duration.

Patients: The study included 43 patients (20 males and 23 females) between the ages of 1.

1,25-dihydroxyvitamin D-mediated hypercalcemia in ovarian dysgerminoma.

Humoral hypercalcemia of malignancy (HHM) is a rare complication of malignant pediatric tumors, specifically those that secrete humoral factor(s), such as parathyroid hormone-related peptide (PTHrP). The authors report a case of severe hypercalcemia associated with ovarian dysgerminoma in a 10-year-old girl. In this case, the humoral factor was considered to be 1,25-dihydroxyvitamin D.

A child with adrenocortical carcinoma who underwent percutaneous ethanol injection therapy for liver metastasis.

The authors encountered a 2-year-old-girl with adrenocortical carcinoma who underwent percutaneous ethanol injection therapy (PEIT) for liver metastasis. The patient had functional adrenocortical carcinoma diagnosed and underwent excision of the tumor in the right adrenal gland. Because liver metastasis was detected 11 months after surgery, the patient underwent PEIT under general anesthesia.
