Application of Mid-Pancreatectomy with End-to-End Anastomosis in Pancreatic Benign Tumors

After making a vertical incision on the anesthetized patient, carefully explore the intraperitoneal organs and peritoneal surface to reveal a mass above the pancreas measuring approximately three centimeters by three centimeters. Using an ultrasonic knife, separate abdominal adhesions and excise a portion of omental tissue. Free the greater curvature side tissues of the gastroepiploic artery with the help of an ultrasonic knife.

Suspend the greater curvature of the stomach using clamps, and expose the pancreas. After intraoperative B ultrasound localization, use an ultrasonic scalpel to cut off one centimeter of normal pancreatic tissue from the edge of the pancreatic mass near the neck of the pancreas. Now, free the splenic artery and vein at the upper posterior of the pancreas with the help of an ultrasonic knife.

Then, free the connective tissue between the tail and body of the pancreas and the splenic vessels. Resect the pancreatic mass completely using an ultrasonic scalpel to remove the normal pancreatic tissue one centimeter proximal to the margin of the pancreatic mass. Place the stent tubes into the proximal and distal sides of the pancreas within the pancreatic ducts.

Suture the pancreatic tissue continuously using 4-0 Prolene and make an extended incision two centimeters below the navel to remove the pancreatic mass. Laparoscopic mid pancreatectomy combined with end-to-end anastomosis showed a decrease in drain amylase levels from 29, 300 units per liter on postoperative day one to 58.39 units per liter on postoperative day five. Venous blood analysis revealed a reduction in carcinoembryonic antigen levels from 5.8 nanograms per milliliter preoperatively to 2.28 nanograms per milliliter postoperatively.

Alpha-fetoprotein levels decreased from 30.53 nanograms per milliliter before surgery to 7.66 nanograms per milliliter after surgery.
