Application value of pancreatoduodenectomy with preservation of the gastric tube / 中华消化外科杂志

ABSTRACT

Objective:To investigate the application value of pancreatoduodenectomy (PD) with preservation of the gastric tube.Methods:The retrospective and descriptive study was conducted. The clinicopathological date of 3 male patients who underwent PD with preservation of the gastric tube for the treatment of periampullary tumor in Nanjing Drum Tower Hospital affiliated to Nanjing University Medical School from May 2018 to November 2019 were collected. The 3 patients were aged from 66 to 77 years, with a median age of 76 years. All 3 patients with surgical history of radical resection of esophageal tumors and tubular gastric surgery underwent PD with preservation of the gastric tube. Observation indications (1) preoperative three-dimensional (3D) reconstruction; (2) surgical and postoperative situations; (3) follow-up. Follow-up using outpatient exa-mination or telephone interview was conducted to detect survival of patients and tumor metastasis and recurrence up to April 2021. Measurement date with skewed distribution were expressed as M(range).Count date were expressed as absolute numbers. Results:(1) Preoperative 3D recons-truction results of preoperative 3D reconstruction for the 3 patients showed none of patients with vascular variation. (2) Surgical and postoperative situations 3 patients underwent PD with preserva-tion of the gastric tube successfully. The operation time and the volume of intraoperative blood loss were 402 minutes(range, 345?480 minutes) and 330 mL(range, 300?400 mL) for the 3 patients. Of 3 patients, 1 case had postoperative grade B pancreatic fistula and 1 case had chylous leakage, respectively, who were improved after conservative treatment. There was no perioperative death. The duration of postoperative hospital stay was 18 days(range, 15?20 days) for the 3 patients. Results of postoperative histopathological examination for the 3 patients showed that 1 case with pancreatic cancer as T2N0M0 stage, 1 case with ampulla carcinoma as T2N0M0 stage and 1 case with intraductal papillary mucinous neoplasms of the pancreas. (3) Follow-up 3 patients were followed up for 12 to 18 months, with a median follow-up time of 16 months. Results of abdominal enhanced computed tomography examination at postoperative 14 month for the 3 patients showed that the right gastroepiploic artery and vein around the pancreas were unobstructed. Of 3 patients, 1 case with pancreatic cancer who did not receive chemotherapy died at postoperative 14 months due to tumor recurrence and metastasis. There was no recurrence and metastasis in the other two cases.Conclusion:PD with preservation of the gastric tube is safe and feasible, which can be used for patients with periampullary lesions who underwent radical resection of esophageal tumors and tubular gastric surgery in the past.
