Comparative study of cylindrical circular ring magnets for colonic anastomosis in rats.

Background: Magnetic compression anastomosis (MCA) offers a simple and reliable technique for inducing anastomoses at any point along the digestive tract. Evidence regarding whether the design of the MCA device influences the anastomosis effect is lacking.

Aim: To investigate any difference in the side-to-side colonic anastomosis effect achieved with cylindrical circular ring magnets.

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.

Optimization of tracheoesophageal fistula model established with T-shaped magnet system based on magnetic compression technique.

Background: The magnetic compression technique has been used to establish an animal model of tracheoesophageal fistula (TEF), but the commonly shaped magnets present limitations of poor homogeneity of TEF and poor model control. We designed a T-shaped magnet system to overcome these problems and verified its effectiveness animal experiments.

Aim: To investigate the effectiveness of a T-shaped magnet system for establishing a TEF model in beagle dogs.

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.

Novel deformable self-assembled magnetic anastomosis ring for endoscopic treatment of colonic stenosis natural orifice.

Background: Although endoscope-assisted magnetic compression anastomosis has already been reported for colonic anastomosis, there is no report on a single-approach operation using the natural orifice.

Aim: To design a deformable self-assembled magnetic anastomosis ring (DSAMAR) for colonic anastomosis for use in single-approach operation and evaluate its feasibility and safety through animal experiments.

Methods: The animal model for colonic stenosis was prepared by partial colonic ligation in eight beagles.

Magnetic compression anastomosis for reconstruction of digestive tract after total gastrectomy in beagle model.

Background: Magnetic compression anastomosis (MCA) is a simple procedure contributing to a reliable anastomosis. However, digestive-tract reconstruction after total gastrectomy using MCA has not yet been reported.

Aim: To investigate the feasibility of MCA for simultaneous esophagojejunostomy and jejunojejunostomy after total gastrectomy using beagle dogs.

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.

Construction of Esophagogastric Anastomosis in Rabbits with Magnetic Compression Technique.

Purpose: The magnetic compression technique (MCT) is a new surgical method that has been used for gastrointestinal anastomosis, choledochojejunostomy, and intestinal anastomosis, but there are no reports on its use for esophagogastric anastomosis. This study aimed to investigate the feasibility of using MCT to fashion esophagogastric anastomoses in rabbits.

Methods: Twenty rabbits were randomized into an MCT group (study group, n = 10) and a hand-sewn group (control group, n = 10).

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 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.

Treatment of rectovaginal fistula by magnetic compression.

Introduction And Hypothesis: Rectovaginal fistula (RVF) is an abnormal epithelium-lined connection between the rectum and vagina. The primary effective treatment is surgical repair, but recurrence remains a challenge. Magnetic compression anastomosis (MCA), an alternative to suturing, has been developed to generate an anastomosis between various hollow viscera.

[Construction and immunogenicity of an attenuated mutant of Actinobacillus pleuropneumoniae by insertional inactivation of apxIC].

Actinobacillus pleuropneumoniae is the aetiological agent of porcine pleuropneumonia. Apx toxin, an exotoxin secreted by A. pleuropneumoniae, is one of the most important virulence factors.
