reinforced pancreaticojejunostomy with or without glubran2

Conditions: Pancreatic Fistula; Pancreas Cancer; Periampullary Carcinoma; Pancreatic Ductal Adenocarcinoma

Summary: pancreatic fistula is one of the most serious complication after pancreatoduodenectomy. to reduce pancreatic fistula, many authors recommend different techniques in pancreatojejunostomy. the purpose of this study is to determine which is the best method in preventing pancreatic fistula by enforce pancreaticojejunostomy with tissue glue and to investigate its long term clinical outcomes.

tissue adhesives have gained popularity in various fields of surgical practice. there are various types of tissue adhesives, each with their own adhesive mechanisms and uses. basically, a tissue adhesive forms bonds with its substrate, ensuring sufficient adhesion. these bonds can either be chemical, of which covalent bonds are the strongest, or physical, including hydrogen bonds or van der waals forces. furthermore, the total strength of the glue bond depends on the balance between interaction within the tissue adhesive (cohesion) and between the tissue adhesive-substrate interface (adhesion). tissue adhesives can either be glues, intended to independently connect various structures (i.e., wound edges), or sealants, used to cover and protect an anastomosis . except for external use, tissue adhesives can also be used intracorporeally. various tissue adhesives are being used in cardiovascular surgery, plastic surgery, and, increasingly, surgery of the gi tract . tissue adhesives are promising tools for wound closure. they distribute forces throughout the wound more evenly and noninvasively than sutures and staples, are strong and flexible, and do not interfere with the wound-healing process. also, the technique of tissue adhesive application to the wound is easy and standardizable, resulting in less variation in technique between surgeons . by using tissue adhesives as sealants of gi anastomosis, enhancing standard anastomotic techniques. numerous research projects have been undertaken to assess the applicability of available tissue adhesives in gi surgery; however, no recent literature provides the surgical community with an up-to-date overview of the progress in this field . in addition to reducing the incidence of post operative pancreatic fistula, external pancreatic duct drainage may have other potential benefits, such as decreasing the length of hospital stay, reducing the need for additional interventions, and improving overall patient quality of life. however, these potential benefits must be weighed against the risks and drawbacks of external pancreatic duct drainage, including the potential for stent-related complications and the need for an additional procedure to remove the stent. •after being informed about the study and potential risks, all patients giving written consent. patients who meet the eligibility requirements will be randomized in a 1:1 ratio to external pancreatic drainage group and no external pancreatic drainage group.

Eligibility criteria:
inclusion criteria: * all the patients undergoing pancreaticoduodenectomy for cancer * patients able to give their informed consent exclusion criteria: * unfit patients for surgery due to severe medical illness. * inoperable patients by imaging studies, irresectable tumors after laparotomy or diagnostic laparoscopy. * presence of distant metastasis . * patients refused to participate in the study.
