Retroperitoneoscopic Left Live Donor Nephrectomy.

Background: Retroperitoneoscopic donor nephrectomy (RDN) approach is an unfamiliar approach to the donor surgeons in Australia and New Zealand due to the background General Surgery training. The learning curve when transitioning from transperitoneal to retroperitonoscopic donor nephrectomy is relatively short with minimal morbidity.

Methods: We detail our standardized surgical approach for performing RDN, including technical tips and maneuvers as well as visual aids that ensure the procedure's safety and efficacy.

Hepatocellular carcinoma recurrence after liver transplant: An Australian single-centre study.

Background: Hepatocellular carcinoma (HCC) is a leading cause of cancer-related deaths worldwide. Liver transplantation (LT) offers the most effective treatment. HCC recurrence is the strongest risk factor that decreases post-LT survival in patients transplanted for HCC.

Emerging materials and technologies for advancing bioresorbable surgical meshes.

Surgical meshes play a significant role in the treatment of various medical conditions, such as hernias, pelvic floor issues, guided bone regeneration, and wound healing. To date, commercial surgical meshes are typically made of non-absorbable synthetic polymers, notably polypropylene and polytetrafluoroethylene, which are associated with postoperative complications, such as infections. Biological meshes, based on native tissues, have been employed to overcome such complications, though mechanical strength has been a main disadvantage.

Liver Transplant for Adult Recurrent Hepatic Mesenchymal Hamartoma and a Feasible Treatment Modality: A Case Report and Literature Review.

Background: Adult hepatic mesenchymal hamartoma (HMH) is an extremely rare hepatic tumor. Recurrence following complete resection is uncommon. Liver transplantation (LT) is described as a possible treatment option in nonresectable HMH.

Umbilical fissure vein, anatomical variation and potential surgical application.

Background: The umbilical fissure vein (UFV) is a hepatic vein that travels within the umbilical fissure (or its proximity), providing venous drainage for hepatic segments 3 and 4. Its preservation carries a potential importance in extended right hemi-hepatectomy, left lateral segmentectomy and extended segment 2 resections.

Methods: Consecutive 1-mm slice thickness portovenous phase intravenous contrast computed tomography (CT) scans of the abdomen performed were retrospectively reviewed during the period of June 2019 to July 2019, with two independent investigators investigating the presence of UFV, its course, insertion and relation to the umbilical fissure.

Long-term outcome of kidney transplant by using restored kidney grafts after tumour ex vivo excision - a prospective study.

The aim of this study is to report long-term outcomes of kidney transplantation by using the kidney graft after a small tumour ex vivo excision. A structured programme was established to use the restored kidney graft from urological referral after radical nephrectomy. The criteria were defined as tumour size ≤3 cm, margin clear on frozen section and recipients aged ≥60 years or those on the urgent list for transplantation as a result of imminent lack of dialysis access.

Atraumatic splenic rupture in a patient treated with apixaban: A case report.

Introduction: Splenic rupture is often seen in the context of significant trauma. Atraumatic ruptures are described in the context of malignancy, inflammation or infection directly affecting the spleen. Splenic ruptures occurring in patients taking apixaban, a factor Xa inhibitor, are challenging due to the scarcity of a direct reversal agent.

Immune-mediated ECM depletion improves tumour perfusion and payload delivery.

High extracellular matrix (ECM) content in solid cancers impairs tumour perfusion and thus access of imaging and therapeutic agents. We have devised a new approach to degrade tumour ECM, which improves uptake of circulating compounds. We target the immune-modulating cytokine, tumour necrosis factor alpha (TNFα), to tumours using a newly discovered peptide ligand referred to as CSG.

InForm software: a semi-automated research tool to identify presumptive human hepatic progenitor cells, and other histological features of pathological significance.

Hepatic progenitor cells (HPCs) play an important regenerative role in acute and chronic liver pathologies. Liver disease research often necessitates the grading of disease severity, and pathologists' reports are the current gold-standard for assessment. However, it is often impractical to recruit pathologists in large cohort studies.

Evaluation of Three-Dimensional Versus Conventional Laparoscopy for Kidney Transplant Procedures in a Human Cadaveric Model.

Objectives: There are increased reports that kidney transplant can be performed by laparoscopic surgery. The further development of this technique could revolutionize human kidney transplant surgery. However, laparoscopic kidney transplant demands a high level of skill for vascular anastomoses.

Bile duct stone formation around a Prolene suture after cholangioenterostomy.

The iatrogenic cause of bile duct stone formation is mainly due to suture materials, especially silk sutures. In recent years, Prolene and Vicryl sutures have been widely used in biliary surgery, and bile duct stone formation related to sutures are seemingly becoming rare, as there has only been one report of bile duct stone formation caused by Prolene sutures in the literature. In the last few years we have had two cases of Prolene suture-related bile duct stone formation within our unit.

Repair of extrahepatic bile duct defect using a collagen patch in a Swine model.

Extrahepatic bile duct (EBD) injury can happen during surgery. To repair a defect of the EBD and prevent postoperative biliary complications, a collagen membrane was designed. The collagen material was porous, biocompatible, and degradable and could maintain its shape in bile soaking for about 4 weeks.

A human cadaver model for laparoscopic kidney transplant.

Objectives: To evaluate the technique of laparoscopic kidney transplant and demonstrate the feasibility of this procedure by an extraperitoneal approach.

Materials And Methods: The procedure was performed on 2 human cadavers. Retroperitoneal endoscopic left nephrectomy was performed.

Laparoscopic surgery for kidney orthotopic transplant in the pig model.

Background And Objectives: Laparoscopic surgery has rapidly expanded in surgical practice with well-accepted benefits of minimal incision, less analgesia, better cosmetics, and quick recovery. The surgical technique for kidney transplantation has remained unchanged since the first successful kidney transplant in the 1950s. Over the past decade, there were only a few case reports of kidney transplantation by laparoscopic or robotic surgery.

Laparoscopic surgery for orthotopic kidney transplant in the pig model.

Background: Laparoscopic surgery has become the preferred approach in surgical practice due to multiple benefits. Over the last decade, kidney transplant by laparoscopic or robotic techniques have been explored. The aim of this study is to establish a new laparoscopic technique for kidney orthotopic transplant.

Focal nodular hyperplasia of the liver: pathological analysis of 11 cases.

Background: Focal nodular hyperplasia (FNH) is a benign tumor-like lesion of the liver, predominantly affecting women. Its etiology is obscure and its pathogenesis is poorly understood. FNH should be differentiated from other benign and malignant hepatic lesions.

Clinical experience in liver transplantation from an organ transplantation center in China.

Objective: To sum up the experience in liver transplantation in a period of ten years at a single center.

Methods: We retrospectively reviewed the clinical records of 120 patients receiving liver transplantation from April 1993 to October 2002. The patients' clinical characteristics, surgical techniques, complications and survival were compared in the phases of 1993-1997 (phase I), 1999 (phase II), and 2000-2002 (phase III).
