Laparoscopic-assisted full-sized liver transplantation with magnetically fast portal vein anastomosis: an initial cohort study.

Background: Some cases of laparoscopic-assisted liver transplantation (LA-LT) with utilization of reduced-size grafts has been reported. The authors here introduced successful utilization of LA-LT with whole liver grafts and magnetic portal vein anastomosis.

Methods: Eight patients with liver cirrhosis were included for LA-LT using donor organs after cardiac death.

Liver transplantation using magnetic anastomosis in pigs.

Magnetic anastomosis substantially shortens the duration of vascular anastomosis. We aimed to apply magnetic anastomosis technology (MAT) to donor liver implantations in pig orthotopic liver transplantation (OLT). Twenty healthy adult pigs were randomly divided into donors and recipients, and major vascular anastomosis was performed using MAT during OLT.

Magnetic-assisted laparoscopic liver transplantation in swine.

Background: Although laparoscopic technology has achieved rapid development in the surgical field, it has not been applied to liver transplantation, primarily because of difficulties associated with laparoscopic vascular anastomosis. In this study, we introduced a new magnetic-assisted vascular anastomosis technique and explored its application in laparoscopic liver transplantation in pigs.

Methods: Two sets of magnetic vascular anastomosis rings (MVARs) with different diameters were developed.

End-to-end vascular anastomosis using a novel magnetic compression device in rabbits: a preliminary study.

Magnetic compression anastomosis (MCA) has been appreciated as an innovative alternative to manual suturing in vascular reconstruction. However, magnetic devices have limitations in their applications. The present study aimed to introduce a newly developed magnetic device for end-to-end vascular anastomosis.

Magnetic Anastomosis Rings to Create Portacaval Shunt in a Canine Model of Portal Hypertension.

Purpose: This study evaluated a novel magnetic compression technique (magnamosis) for creating a portacaval shunt in a canine model of portal hypertension, relative to traditional manual suture.

Methods: Portal hypertension was induced in 18 dogs by partial ligation of the portal vein (baseline). Six weeks later, extrahepatic portacaval shunt implantation was performed with either magnetic anastomosis rings, or traditional manual suture (n = 9, each).

Magnetic Anastomosis for Biliojejunostomy: First Prospective Clinical Trial.

Background: Magnetic compression anastomosis (magnamosis, MCA) has been verified safe and effective by us and others in animal bilioenteric anastomosis (BEA). The objective of the present study was to introduce clinical application of magnetic compression bilioenteric anastomosis (MC-BEA) with a unique device in series of patients.

Methods: Patients with obstructive jaundice with an indication of BEA were prospectively enrolled from 2012 to 2015.

Fast magnetic reconstruction of the portal vein with allogeneic blood vessels in canines.

Background: The resection and reconstruction of large vessels, including the portal vein, are frequently needed in tumor resection. Warm ischemia before reconstruction might have deleterious effects on the function of some vital organs and therefore, how to reconstruct the vessels quickly after resection is extremely important. The present study was to introduce a new type of magnetic compression anastomosis (MCA) device to establish a quick non-suture anastomosis of the portal vein after resection in canines.

Healing of stoma after magnetic biliary-enteric anastomosis in canine peritonitis models.

Objective: To assese the healing of stoma after magnetic anastomosis for the reconstruction of biliary-enteric continuity under severe inflammation.

Methods: Acute bile duct injury was constructed as a bile peritonitis model in mongrel dogs (n=32). Magnetic anastomosis (group A, n=16) and traditional suture anastomosis (group B, n=16) were performed to reconstruct the biliary-enteric continuity in one stage.

[Systematic review of gastrointestinal injury caused by magnetic foreign body ingestions in children and adolescence].

Objective: To study the diagnosis and treatment of gastrointestinal injury caused by magnetic foreign body ingestions in children.

Methods: A literature search was performed to identify all the studies related to gastrointestinal tract injury caused by ingesting magnetic foreign body using databases including Google, Medline, ISI Web of Knowledge, Ovid, Wanfang data, VIP, CNKI, degree dissertation, meeting abstracts, and request for document delivery. Language was limited to English, Chinese, Japanese, and Korean.
