RESUMEN
Objective:To explore the safety key points of total pancreaticoduodenectomy in the era of vascular resection technology and the important factors affecting rapid postoperative recovery.Methods:The clinical data of 52 patients with pancreatic cancer who underwent total pancreaticoduodenectomy in Beijing Chaoyang Hospital Affiliated to Capital Medical University from November 2014 to September 2022 were retrospectively analyzed, including 34 males and 18 females, aged (62±9). The intraoperative situation, incidence of postoperative complication, postoperative blood glucose control and postoperative survival rate were analyzed.Results:All operations of the 52 patients were successfully completed, including 48 patients underwent total pancreaticoduodenectomy combined with portal vein resection and allograft vascular grafts via artery approach. The portal vein occlusion time was (20±5) min. The incidence of postoperative complications was 28.8% (15/52), including 2 cases of abnormal gastric empty, 2 cases of diarrhea, 2 cases of chylous fistula, 4 cases of abdominal infection, 1 case of gastrointestinal fistula, 3 cases of gastrointestinal bleeding, and 1 case of pulmonary infection. Subcutaneous short-acting insulin injection was used to control blood glucose in the early stage after surgery, short-acting insulin combined with long-acting insulin was used for subcutaneous injection before sleep for diet recovery. All patients did not experience uncontrolled hyperglycemia. The median survival time of 52 patients was 13 months, and the longest follow-up time was 38 months. There were 37 patients died of tumor recurrence, 4 patients died of cardiovascular and cerebrovascular accidents, and 1 patient died of pulmonary infection in the 42 died patients.Conclusions:Total pancreaticoduodenectomy via artery approach can improve the R 0 resection rate in pancreatic cancer patients with vascular invasion, the rate of postoperative complication and mortality has no significant increase. The postoperative blood sugar control is satisfactory and the quality of life is guaranteed.
RESUMEN
Objective To investigate the clinical efficacy of total pancreaticoduodenectomy combined with portal vein resection and allograft vascular grafts for pancreatic cancer with vascular invasion.Methods The retrospective and descriptive study was conducted.The clinicopathological data of 9 patients with pancreatic cancer who underwent total pancreaticoduodenectomy combined with portal vein resection and allograft vascular grafts in the Beijing Chao Yang Hospital of Capital Medical University from January 2014 to September 2016 were collected.There were 4 males and 5 females,aged from 53 to 78 years,with a median age of 60 years.Involvement of portal vein (PV) and (or) superior mesenteric vein (SMV),splenic vein or convergence was detected in patients by preoperative evaluation,which indicated borderline resectable pancreatic cancer.Patients underwent complete surgical resection of tumor and involved portal veins,and then underwent vascular and digestive tract reconstruction.Observation indicators:(1) intraoperative situations;(2) postoperative situations;(3) follow-up.Patients were followed up by telephone interview and outpatient examination to detect survival of patients up to October 2018.Measurement data with normal distribution were represented as Mean±SD,measurement data with skewed distribution were expressed as M (range),and count data were expressed as absolute number.Results (1) Intraoperative situations:9 patients underwent total pancreaticoduodenectomy combined with portal vein resection and allograft vascular grafts successfully,including 1 undergoing total pancreaticoduodenectomy due to positive margin of pancreatic neck during pancreatico-duodenectomy for pancreatic head carcinoma,3 of pancreatic head carcinoma with portal vein involvement and atrophy of pancreatic body and tail,and 5 of carcinoma of pancreatic neck and body with portal vein involvement.The operation time,portal vein occlusion time,and volume of intraoperative blood loss were (573± 19) minutes,(21 ±4) minutes,and (717±33) mL.(2) Postoperative situations:4 of 9 patients had postoperative complications,including 2 with grade Ⅰ complication and 2 with grade Ⅱ complication.There was no grade Ⅲ or above complication.No anastomotic stenosis or thrombus formation after reconstruction for portal vein.The perioperative complications were cured after conservative treatment.Duration of postoperative hospital stay was 17 days (range,10-25 days).Nine patients underwent subcutaneous injection of insulin to control blood glucose during the period fasting for solids and liquids.After resuming the semi-liquid diet of diabetes,patients received subcutaneous injection of rapid acting insulin before meals combined with subcutaneous injection of long-acting insulin before bedtime,with a insulin need of 24-36 U/d.Patients had postprandial blood sugar level of 8-11 mmol/L,without unmanageable hyperglycemia orlong-term application of insulin pump.Patients received oral trypsin pancreatin instead of trypsin,with no gastrointestinal symptoms such as bloating and steatorrhea,no malnutrition.Of 9 patients,2 had well-differentiated adenocarcinoma,4 had moderately differentiated adenocarcinoma,and 3 had poor-differentiated adenocarcinoma.There were 3 patients with no vascular invasion,1 with endangidic invasion,5 with tumor infiltration of tunica adventitia vasorum.One of 9 patients was in IIA stage of TNM staging,3 were in the II B stage,and 5 were in IIIB stage.The negative rate of pathological sections for excised specimen margin was 8/9.(3) Follow-up:9 patients were followed up for 7-37 months,with a median follow-up time of 15 months.Four patients survived,4 died of tumor recurrence and metastasis,and 1 died of cerebrovascular accident.Conclusion Total pancreaticoduodenectomy combined with portal vein resection and allograft vascular grafts is safe and feasible for pancreatic cancer involving portal vein,splenic vein or junction.
RESUMEN
Objective To study the clinical outcomes of 28 pancreatic cancer patients who underwent total pancreaticoduodenectomy.Method The clinical data of 28 patients with pancreatic cancer who underwent total pancreaticoduodenectomy from January 2009 to March 2015 were retrospectively analyzed.Results Among the 28 patients,complications occurred in 11 (39.2％) after the operation.There were 7 patient having Grade Ⅱ,4 Grade] complications.No patient died within 30 days after the operation.Fol low-up of 25 patients showed a median survival of 13.5 months.There were 24 patients with pancreatic ductal adenocarcinoma,and the median survival was 13 months.Conclusions Total pancreaticoduodenectomy could not improve long-term survival but it decreased postoperative complications and improved postoperative quality of life.In selected patients,total pancreaticoduodenectomy could be a rational option.
RESUMEN
Objective To investigate the clinical efficacy of total pancreaticoduodenectomy for the pancreatic head adenocarcinoma with positive neck margin.Methods The clinical data of 15 patients with pancreatic head adenocarcinoma and had positive neck margin who received total pancreaticoduodenectomy at the Union Hospital of Fujian Medical University from August 2009 to May 2014 were retrospectively analyzed.Patients were followed up by out-patient examination or telephone interview till August 2014.Results Total pancreaticoduodenectomy was successfully carried out on the 15 patients.The operation time was 4.0-10.0 hours (mean,6.5 hours),and the volume of blood loss was 300-2 000 mL (mean,800 mL).The duration of postoperative hospital stay was 13.0-35.0 days (mean,22.3 days).The main postoperative complications included pulmonary infection (3 cases),abdominal infection (2 cases)and low blood glucose (2 cases).No interoperative death,bile leakage or gastrointestinal anastomotic fistula occurred.The blood glucose of most of the patients was controlled by insulin or pancreatin.No stomachache,steatorrhea or malnutrition occurred in all the patients.The mean time of postoperative follow-up was 21 months (range,3 months to 5 years).Three patients survived within 1 year,2 survived for 1-2 years,5 survived for more than 2 years and 1 survived for more than 5 years.Four patients with follow-up time under 6 months survived till now.Five patients had liver metastasis at postoperative month 6.Conclusion Total pancreaticoduodenectomy might be necessary for the pancreatic head adenocarcinoma with positive neck margin to achieve R0 resection.
