One-layer Versus Two-layer Duct-to-mucosa Pancreaticojejunostomy After Pancreaticoduodenectomy .
One-layer Versus Two-layer Duct-to-mucosa Pancreaticojejunostomy After Pancreaticoduodenectomy : Randomized Comparative Prospective Study .
Postoperative 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.
Study Overview

Detailed Description
To date, pancreaticoduodenectomy (PD) has been regarded as the only potentially curative treatment for pancreatic head and periampullary tumors, including tumors in the ampullary region, distal biliary duct, and periampullary duodenum .
A retrospective study in which 1000 cases were recruited over the past three decades showed that PD has become an effective treatment to reduce hospital mortality. Mortality has been reduced to less than 5 %, but the morbidity remains at 30-50 % .
Postoperative 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.
POPF risk is increased by many factors including pancreatic texture, main pancreatic duct diameter, and pancreaticojejunal (PJ) anastomotic technique .Among these factors, only anastomotic technique can be improved. According to the International Study Group of Pancreatic Surgery (ISGPS) definition, POPF exists if the drainage of any measurable volume of fluid containing amylase exceeds three times the normal serum value on or after postoperative day (POD) 3.
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.

Intervention / Treatment |
---|---|
Experimental: One-layer Duct-to-mucosa Pancreaticojejunostomy
pancreatic anastomosis to jejunum will be performed in one layer suturing the pancreatic duct to the mucosa of jejunum.
|
To create the anterior suturing layers, double needles with a 4/0 or 3/0 Prolene line will be used; one side of the needles will be inserted from the anterior inner side of the pancreatic duct and out through the ventral parenchyma of the pancreatic stump to the anterior surface of the pancreas about 3 cm from the cut edge.
The other side of the needles will be started from the inner side of the jejunum lumen, then pushed through the subserosa and seromuscular region, and out from the posterior surface of the bowel but its done after completion of the posterior layer.
The posterior suturing layer will be treated in the same manner.
An internal pancreatic duct stent will be used
|
Experimental: Two-layer Duct-to-mucosa Pancreaticojejunostomy
pancreatic anastomosis to jejunum will be performed in two layer.
The first layer will be suturing the pancreatic capsule to the seromuscular layer of jejunum and the 2nd layer will be suturing the pancreatic duct to the mucosa of jejunum.
|
The same double needle and 4/0 or 3/0Prolene line will be used.
First, the region approximately 1.0 cm from the cutting edge of the pancreatic remnant will be freed; then, the posterior surface of the pancreatic remnant will be sutured to the seromuscular layer of the jejunum using the interrupted suturing method.
The jejunum will be brought closer to the stump of the pancreas, and a hole of similar diameter to the main pancreatic duct will be made on the jejunum near the entrance of the main pancreatic duct.
The posterior wall of the jejunum near the hole will be sutured to the posterior wall of the pancreatic duct using the interrupted suturing method with Prolene line, and a suitable internal pancreatic duct stent will used .
The interior side of the jejunum and pancreas will be sutured using the same method.
Then, the anterior surface of the pancreatic remnant and the seromuscular layer of the jejunum will be tightly sutured using the interrupted method.
