	</ol>
	</li>
</ol>
3. Postoperative care
<ol>
	<li>After LPD surgery, patients undergo treatment such as fasting, infection prevention, and venous malnutrition, and other treatments. Eating liquid after an anal exhaust reduces the amount of infusion.</li>
	<li>At 3 days after surgery, measure amylase levels in the abdominal drainage fluid. Ensure that the concentration of amylase is not higher than three times the upper limit of the normal range of serum amylase.</li>
	<li>When the patient has no gastrointestinal leakage or abdominal infection, gradually remove the abdominal drainage tube. Ensure no liquid discharge or clear liquid discharge which is less than 20 mL before removal of the drainage tube. 
	NOTE: Definition of postoperative pancreatic fistula: In 2016, the International Group of Pancreatic Surgeons (ISGPS) updated the definition and grading of postoperative pancreatic fistula. When the postoperative time is greater than 3 days, the amylase content in the drainage fluid is greater than 3 times the upper limit of the normal serum amylase value, and it is related to the clinical treatment prognosis. The 2016 postoperative pancreatic fistula grading is given in Table 1.</li>
	<li>If a pancreatic fistula occurs after surgery, perform conservative treatment. If conservative treatment is ineffective, perform an invasive treatment.</li>
	<li>Change the incision dressing every 3 days after surgery and remove the incision stitches 10 days after surgery. The patient&#39;s general condition is good, with no complications, no discomfort such as fever or abdominal pain, and can be discharged.</li>
	<li>Upto 2 years after discharge, ask the patient to return to the hospital for follow-up every 3 months to understand the patient&#39;s general condition, digestive function, and whether there is tumor recurrence and metastasis or not.</li>

Blumgart pancreaticointestinal anastomosis is a pancreatic intestinal anastomosis technique pioneered by Professor Blumgart at Memorial Sloan Kettering Cancer Center Hospital in 20028. Since its application, Blumgart&#39;s pancreaticointestinal anastomosis has gradually been proven to be a safe and effective surgical method due to its lower incidence of pancreatic fistula9. The application of this anastomosis is also controversial: if 4-6 non-absorbable threads are needed, ...

Laparoscopic pancreaticoduodenectomy (LPD) is mainly used to treat malignant tumors around the pancreatic head and ampulla. As first described by Gagner and Pomp in 1994, LPD has the advantages of short hospitalization time and low accidental readmission rate. Compared with traditional open pancreaticoduodenectomy, it has outstanding advantages in reducing pain and shortening hospital stay1,2. Pancreatic leakage is a common complication of LPD, and severe pancreatic leakage can endanger the patient&#39;s life. The occurrence of pancreatic fistula is influenced by various factors. Choosing a reasonable method for pancreatic and intestinal reconstruction can effectively reduce the incidence of postoperative pancreatic fistula, which is the key to successful surgery3. In order to reduce the occurrence of pancreatic leakage, especially severe pancreatic leakage (grade B/C), pancreatic surgeons have continuously improved and innovated the LPD pancreaticointestinal anastomosis method in recent years.
At present, there are problems with pancreatic intestinal anastomosis in LPD: pancreatic jejunal mucosal anastomosis is one of the most widely used pancreatic intestinal anastomosis methods, first proposed by Varco in 19454. It conforms to the growth pattern of mucosa physiologically and can promote the biological healing of pancreatic duct mucosa and jejunal mucosa, making it a widely recognized pancreaticointestinal anastomosis internationally5. Due to the unique perspective, operational limitations, and lack of tactile sensation of laparoscopic suturing, the anastomosis of the pancreatic duct and jejunal mucosa is complex and requires high-level laparoscopic suturing techniques. For patients with small pancreatic ducts (&#60; 3 mm) and soft and fragile pancreatic tissue. Even skilled surgeons cannot guarantee the quality of the fit.
The aim of this study is to introduce a laparoscopic reverse needle continuous suture of the pancreatic duct for jejunal mucosal pancreaticointestinal anastomosis in LPD and summarize our experience. This technique uses a 5-0 PDS suture to continuously suture the pancreatic duct and jejunal mucosa. Compared with traditional laparoscopic anastomosis of the pancreatic duct and jejunal mucosa, its advantages include better alignment with the laparoscopic operating perspective, reduced suture difficulty, shorter surgical time, lower incidence of pancreatic leakage, and less suture thread consumption.

reverse needle continuous suture of the pancreatic duct to jejunal mucosal pancreaticointestinal anastomosis in laparoscopic pancreaticoduodenectomy

Reverse Needle Continuous Suture of the Pancreatic Duct to Jejunal Mucosal Pancreaticointestinal Anastomosis in Laparoscopic Pancreaticoduodenectomy

Laparoscopic pancreaticoduodenectomy (LPD) is considered the Mount Everest surgery in laparoscopic surgery due to its complex surgical process, high technical requirements, and high incidence of complications. Pancreatic leakage is a common complication of LPD, and severe pancreatic leakage can endanger the patient's life. The occurrence of pancreatic leakage is influenced by multiple factors, and the choice of pancreaticointestinal anastomosis method and the quality of anastomosis are the only controllable factors during surgery. In order to reduce the occurrence of pancreatic leakage, especially severe pancreatic leakage (grade B/C), pancreatic surgeons have continuously improved and innovated the LPD pancreaticointestinal anastomosis method in recent years. Pancreatic duct jejunal mucosal anastomosis is one of the most widely used pancreatic intestinal anastomosis procedures and has been internationally recognized. Due to the unique perspective, operational limitations, and lack of tactile sensation of laparoscopic suturing, it is difficult to complete the anastomosis of the pancreatic duct and jejunal mucosa under laparoscopy for patients with small pancreatic ducts (&#60; 3 mm) and soft and fragile pancreatic tissue. Our team innovatively applied laparoscopic reverse needle continuous suturing of the pancreatic duct to the jejunal mucosa for pancreas-intestine anastomosis. Compared with the traditional laparoscopic pancreatic duct to jejunal mucosa for pancreas intestine anastomosis, it is more in line with the laparoscopic operation perspective, reduces the difficulty of suturing, shortens the anastomosis time, improves the quality of anastomosis, and reduces the occurrence of pancreatic leakage. Moreover, it can reduce the consumption of sutures and minimize the number of knots.

From February 2022 to December 2024, the same medical team innovatively used reverse needle continuous suture of the pancreatic duct for 32 cases of jejunal mucosal pancreaticojejunostomy in LPD. According to the 2016 version of the postoperative pancreatic fistula grading criteria7, there were 3 cases of B-grade pancreatic fistula, with an incidence rate of 9.4%. There was no C-grade pancreatic leakage, and good treatment results were achieved. We retrospectively analyzed the main intraoperative ...

To circumvent the difficulty in completing the anastomosis of the pancreatic duct and jejunal mucosa under laparoscopy for patients with a small pancreatic duct and soft and fragile pancreatic tissue, we introduce a reverse needle continuous suture technique for laparoscopic pancreaticojejunostomy of the pancreatic duct and jejunal mucosa.

Laparoscopic pancreatoduodenctomy (LPD) may offer advantages over open pancreatoduodenectomy, including early postoperative mobilization, less delayed gastric emptying and a shorter hospital stay. However, LPD is technically challenging and not well-standardized, especially regarding the pancreatic anastomosis. We describe a standardized technique for the pancreatic anastomosis during LPD: modified Blumgart pancreaticojejunostomy.
