Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Magnetic anastomosis has been attempted in biliary and intestinal reconstruction. Based on our initial experience, the investigators have successfully utilized magnetic anastomosis for biliojejunostomy and pancreaticojejunostomy during pancreaticoduodenectomy. The current study was to design a prospective and case-control study with utilization of magnetic compression anastomosis for pancreaticojejunostomy and biliojejunostomy in Whipple's procedure versus traditional hand-sewn technique on the postoperative morbidity, such as biliary/pancreatic fistula, hemorrhage, anastomotic stenosis, etc. In addition, the investigators are seeking to assess the safety and formation of the anastomosis by magnetic technique.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The magnets used in the current study consists of a mother and daughter magnets. An 8-Fr nasogastric tube is tightly fixed with the mother magnet, which will be used for bile or pancreatic drainage before formation of anastomoses. The outside diameter (OD) of the magnets ranges from 5mm to 15mm. In fact, for biliojejunostomy, larger magnets are applied, whereas for pancreaticojejunostomy, smaller magnets are routinely used. This study is a single-center, parallel controlled trial to evaluate the safety and effectiveness of magnetic compression technique for biliojejunostomy and pancreaticojejunostomy, versus traditional hand-sewn techniques on the postoperative morbidity of the patients. And also how to avoid mutual attraction of the two pairs of magnets, formation of bilio-/pancreaticojejunostomy time, discharge rule of the magnets will be all evaluated in the current study.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Patients with age between 18 to 75
* Patients' gender was not limited
* Patients who were well-diagnosed and had the indication for anastomosis.
* Patients whose lifetimes will be longer than 12 months.
* Patients who are willing to join this clinical trial and informed consent form voluntarily.

Exclusion Criteria

* Woman during pregnancy or lactation or anyone with mental disorder
* The wall of biliary duct or jejunum was too thick so that the attractive force of magnetic device cannot meet the requirements of compression.
* Any anatomical variation in bile ducts system or the inner diameter is too small so that the magnetic device cannot place in.
