About this study
Official title: Shark Mouth Modified Pancreaticojejunostomy in Pancreaticoduodenectomy Procedure
Pancreaticoduodenectomy (PD) is one of the most complicated surgical procedure and one of the standard treatments for benign and malignant disease of pancreatic head and periampullary region. Improvements in surgical techniques and the perioperative management of patients undergoing PD have reduced the surgical mortality rates to less than 3% in high-volume medical centers. However, the incidence of postoperative complication remains high, which ranges from 30% to 50% and the pancreatic fistula rate ranges from 5% to 40%. The key point of PD is still the enteric reconstruction of pancreatic stump. There were different techniques of enteric reconstruction, including: invagination pancreaticojejunostomy, binding pancreaticojejunostomy, duct-to-mucosa pancreaticojejunostomy, Roux-en-Y pancreaticojejunostomy, and pancreaticogastrostomy and each technique had its advantages and disadvantages. We established a new digestive reconstruction technique named shark mouth modified pancreaticojejunostomy, which had theoretical advantages including easier performed; lower tension and less complication. The shark mouth modified pancreaticojejunostomy is an end-to-end pancreaticojejunostomy procedure which is between invagination pancreaticojejunostomy and binding pancreaticojejunostomy.The remnant of jejunum is shaped as shark mouth and then sutured with the pancreas remnant. After the surgery, the patients will be well followed up. The pancreaticojejunostomy time, post-operation complication, mortality and hospital stay will be documented to study the safety, efficiency and advantage of this new procedure.
Read the detailed description
A pancreaticoduodenectomy (PD) still remains the curable treatment choice for most of malignant and benign neoplasms of the head of the pancreas and periampullary region. Though the safety of PD has been significantly improved, the post-operative pancreatic fistula (POPF) always is a formidable complication. More and more attention was focused on the different procedure of enteric reconstruction of pancreatic stump, which might be the key point to reduce the POPF.
This is a prospective clinical trial performed in the general surgery department of Peking University Third Hospital. All pancreatic remnants are reconstructed with the method of Shark Mouth Modified Pancreaticojejunostomy. Shark Mouth Modified Pancreaticojejunostomy is performed as standardized procedure and all the detailed data of this procedure is documented, including gland texture, pancreas duct diameter, size of the stent, width of the pancreatic stump and diameter of the jejunum transverse incision. Silicone tube is inserted as internal stents and fixed on the pancreas remnant with non-absorbable sutures. The distal end of the tube should exceed the anastomosis of the common bile duct and jejunum. The same perioperative management strategies are conducted in all patients. Drainages are placed in all patients during the surgeries. Prophylactic somatostatin analogue are used in all cases for 3 days post operations.
Theoretically, the incision of "Shark Mouth" might facilitate the pancreaticojejunostomy especially for the large pancreatic remnant; the feature of anastomosis might reduce the tension of pancreaticojejunostomy, which is important for the healing of anastomosis and might reduce the risk of POPF in the soft pancreas; the characters of anastomosis permits total drainage of pancreatic remnant, which is crucial in the situation of thinner pancreatic ducts.The purpose of this study is to evaluate the new anastomosis called "Shark Mouth Modified Pancreaticojejunostomy", especially the morbidity of POPF.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Shark Mouth Modified PancreaticojejunostomyProcedure or surgery
The remnant of jejunum is closed by continuous suture. The transverse incision is made on the posterior wall of the jejunum (5 centimeters distal to remnant）, which starts at 0.2 centimeter to the mesenteric border and should never exceed the anti-mesenteric border . In case of large pancreas remnant, a longitudinal jejunum incision will be done at anterior part of anastomosis.
The posterior part of anastomosis is two layers of intermittent suture, including seromuscular suture layer and full thickness suture layer. The anterior part of anastomosis is a single layer full thickness suture. At last, the seromuscular layer of the proximal jejunum is sutured with the anterior pancreatic capsule to cover the anterior part of anastomosis.

Questions about this trial
What is this clinical trial studying?
An observational study of Pancreatic Cancer and Periampullary Carcinoma, run by Peking University Third Hospital at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 5 Apr 2018. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Wang hangyan, Doctor (15611963104 ext. 01082267328, wanghangyan111@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
pancreatic fistula (time frame: From 3 days after operation until the date of discharge or date of drains removal, whichever came first, assessed up to 90 days). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03366038, which also lists 3 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Apr 2018.
