One-layer Versus Two-layer Duct-to-mucosa Pancreaticojejunostomy After Pancreaticoduodenectomy ....
Pancreatic FistulaPostoperative pancreatic fistula (POPF) is one of the most frequent and ominous complications after PD, and its occurrence reportedly ranges from 2-40 %. Severe POPF prolongs hospital stay and requires the use of specific treatments, such as the use of antibiotics, nutritional support, endoscopy, interventional radiology, and/or reoperation, etc.. Several anastomotic surgical techniques have been developed to reduce the incidence of pancreatic fistula in recent decades, including the duct-to-mucosa method, pancreaticogastrostomy, Peng's binding method, and the "end-to-end" or "end-to-side" invaginated method. Among these techniques, the conventional duct-to-mucosa method remains the most popular anastomosis due to its advantages. The size of the pancreatic remnant is not limited; moreover, the jejunal lumen and pancreatic remnant lead to easier anastomosis . Compared with two-layer duct-to-mucosa anastomosis, the novel one-layer duct-to-mucosa PJ anastomosis method has been reported to be efficient at reducing POPF occurrence. However, the two cited retrospective studies might lead to selection bias. Because this evidence is insufficient, we will conduct a randomized controlled trial to verify the superiority of one-layer duct-to-mucosa PJ anastomosis after PD over the two-layer technique.
HYPAR Trial - Hydrocortisone vs. Pasireotide in Reducing Pancreatic Surgery Complications
Pancreatic FistulaPancreatic NeoplasmsPancreatic resections carry a high risk for complications, especially pancreatic fistula. Both hydrocortisone and pasireotide have been shown to be effective in reducing complications in earlier RCTs. The aim of this study is to compare the effectiveness and safety of these two drugs in preventing complications of pancreatic surgery.
The Microbiome of Pancreatic Cancer: "PANDEMIC" Study
Microbial ColonizationPancreas Cancer2 moreMicrobiome in patients affected by pancreatic ductal adenocarcinoma may present specific and identifiable patterns. These variations could affect the surgical outcome and increase the risk of life-threatening infections supported by multidrug-resistant bacteria. The identification of microbial signatures with tumor specificity may have a potential role in postoperative risk stratification. Variation of pancreatic, intestinal or bile microbiome and their relationship can be investigated and measured as promising tools in order to predict and overcome the clinical and infectious burden imposed by MDR infections. The prospect of a potential role for probiotics to promote competition against the pathogens and to improve the gastrointestinal barrier integrity has also been raised. Moreover, if the bacterial composition in human PDAC was confirmed to be distinct from that of the normal pancreas, microbiome variation could be used as a potential biomarker, to assess the potential for malignancy in precursor neoplastic lesions. However, we believe that a preliminary and explorative study is necessary. The study aims to outline the pancreatic microbiome of patients who undergo upfront PD for resectable PDAC and to characterize the possible association between bacterial composition and the occurrence of post-operative complications, particularly POPF and IC.
Prognostic Factors in Periampullary Tumors and Cysts

Monitoring of patIents With Microdialysis Following Pancreaticoduodenectomy
Pancreatic CancerPancreatic Neoplasms3 moreA pancreaticoduodenectomy is performed in patient with pancreatic cancer. The most common and serious complication is leakage between the intestine and the remnant pancreas after this procedure. It occurs in 20-30%. The result is often prolonged hospital and ICU stay, reoperations and deaths (3-5%). To detect a leakage early before the patient becomes seriously ill, thereby initiating treatment is therefore very important. By inserting a thin microdialysis catheter near the anastomosis between pancreas and intestine before closure of the abdominal wall, the investigators will analyze substances such as lactic acid, pyruvate, glycerol, etc. and if these substances may reveal anastomosis leakage at an early stage. Observational studies have shown that if a leakage occurs, glycerol concentration in the microdialysate will rise significant after few hours, and changes in lactic acid and pyruvate values will change as a sign of inflammation. The investigators want to conduct a randomized study comparing patients undergoing pancreaticoduodenectomy and using microdialysis in half of the included population.

ERAS Protocol in Pancreaticoduodenectomy and Total Pancreatectomy
Pancreatic CancerSurgery--Complications3 moreIn the study, the enhanced recovery after surgery (ERAS) program is applied to total pancreatectomy (TP) and low-risk pancreaticoduodenectomy (PD) patients identified by a small number of acinar cells in the cut edge of the pancreas. The research setting is randomized and controlled. All patients arriving at the Tampere University Hospital (TAUH) for PD or TP surgery are recruited into the study. Recruited patients are randomized to the ERAS protocol and to the standard protocol recovery program. The ERAS program differs from the normal care protocol preoperatively, intraoperatively and postoperatively as explained in the following section. In the ERAS protocol, both on the previous day of the surgery and on the following days, the patient is discussed with the patient about the benefits of the protocol used and the recovery program objectives. The purpose is to motivate and encourage the patient. On the day of surgery, the patient's intake of food and fluids is allowed to be closer to the surgery and the patient is also given a carbohydrate drink two hours before surgery. The nasogastric tube set at the beginning of surgery is removed at the end of the surgery and peripancreatic or perihepatic drains are not routinely placed. After surgery, drinking is allowed after four hours and the patient is encouraged to move as actively as possible in the bed. On the first and second postoperative day, the patient is allowed to enjoy normal food and drink according to his or her ability, and pancreatic capsules are given in the course of food. Additionally, the analgesic to be administered through the epidural cannula is dosed as far as possible to allow mobilization of the patient. The discussion on the benefits and recovery targets of the ERAS protocol are continued. On the third postoperative day, the epidural infusion is discontinued and the pain medication is moved to opioid-based pain management. This is continued until specific criteria for passing to the follow-up care are met. Typical complications (pancreatic fistula, delayed gastric emptying, postpancreatectomy hemorrhage) are registered during hospitalization and their severity ratings according to ISGPS, ISPGF and Clavien-Dindo classifications are also determined. Other variables registered are the number of intensive care days, situations requiring new surgeries, 30 and 90 day mortality, the completion time of the criteria for passing to follow up care, and the total length of hospitalization. In addition, the need for readmissions is registered. The implementation of the ERAS protocol is followed by a separate tracking template, in which the nurses record the progress of the goals specified in the protocol on a daily basis. The results of the study are analyzed with the intention-to-treat principle.
