ABSTRACT
Objective To explore the clinical application value of modified invagination for pancreaticojejunostomy in pancreaticoduodenectomy (PD).Methods The retrospective cohort study was conducted.The clinicopathological data of 39 patients who underwent PD in the Affiliated Hospital of Inner Mongolia Medical University from January 2014 to December 2017 were collected.There were 26 males and 13 females,aged (60±7)years,with a range of 41-75 years.All the 39 patients underwent PD,using Child method to reconstruct digestive tract.Of 39 patients,19 undergoing modified invagination for pancreaticojejunostomy and 20 undergoing mucosa-to-mucosa end-to-side pancreaticojejunostomy were allocated to innovative group and traditional group,respectively.Observation indicators:(1)surgical situations;(2) postoperative complications;(3) follow-up.Follow-up was performed by outpatient examination and telephone interview to detect postoperative tumor recurrence,main pancreatic duct dilatation,survival,and discomfort (abdominal pain,bloating,indigestion,etc.) of patients up to October 2018.Measurement data with normal distribution were represented as Mean±SD,and comparison between groups was analyzed by t test.Measurement data with skewed distribution were represented as M (P25,P75) or M (range),and comparison between groups was analyzed by Mann Whitney U test.Count data were expressed as absolute numbers,and comparison between groups was analyzed by chi-square test or Fisher exact probability.Results (1) Surgical situations:operation time,volume of intraoperative blood loss,cases with soft pancreas or hard pancreas (pancreatic texture),pancreatic duct diameter,time of pancreatic duct removal,cases using somatostatin,and duration of postoperative hospital stay of the innovative group were (342±47) minutes,400 mL (300 mL,400 mL),10,9,3.1 cm (2.9 cm,3.4 cm),37 days (32 days,63 days),17,18 days (15 days,22 days),respectively,versus (392±95)minutes,400 mL (300 mL,525 mL),6,14,3.6 cm (2.6 cm,4.2 cm),43 days (34 days,49 days),18,and 24 days (15 days,27days) of the traditional group;there was no significant difference in the volume of intraoperative blood loss,cases with soft pancreas or hard pancreas (pancreatic texture),pancreatic duct diameter,time of pancreatic duct removal,cases using somatostatin,and duration of postoperative hospital stay between the two groups (Z=-0.775,x2 =2.063,Z=-1.155,Z=-0.295,x2 =0.003,Z=-1.286,P＞0.05);but a significant difference in operation time between the two groups (t =-2.114,P＜0.05).(2) Postoperative complications:6 patients in the innovative group had complications,including 1 of delayed gastric emptying,1 of wound infection,1 of pulmonary infection,1 of acute respiratory failure,1 of perihepatic effusion,and 3 of grade A pancreatic leakage;11 patients in the traditional group had postoperative complications,including 1 of bile leakage,2 of delayed gastric emptying,4 of abdominal infection,4 of wound infection,2 of pulmonary infection,1 of ascites,1 of abdominal hemorrhage,1 of pleural effusion,2 of grade A pancreatic leakage,5 of grade B and C pancreatic leakage;the same patient had multiple complications.There was no significant difference in postoperative complications between the two groups (x2=2.174,P＞0.05),but there was a significant difference in postoperative grade B and C pancreatic leakage between the two groups (P＜O.05).Patients with postoperative complications were improved after symptomatic support treatment,and no patient died during the perioperative period.(3) Follow-up:of the 39 patients,33 (18 in the innovation group and 15 in the traditional group) were followed up for 3-57 months,with a median follow-up time of 17 months.Of the 18 patients receiving follow-up in the innovative group,5 died of tumor recurrence and metastasis,with a survival time of 5-24 months,1 had tumor recurrence at 34 months after operation,1 had main pancreatic duct dilatation and intermittent abdominal pain and abdominal distension,5 had indigestion,1 had back pain,and 5 had good recovery.Of 15 patients receiving follow-up in the traditional group,10 died of tumor recurrence and metastasis,with a survival time of 3-57 months,2 had main pancreatic duct dilatation and intermittent abdominal pain and abdominal distension,2 had indigestion,1 had good recovery.Conclusion Compared with the traditional mucosa-to-mucosa end-to-side pancreaticojejunostomy,modified invagination for pancreaticojejunostomy in the PD is safe and feasible,which can simplify the operation,reduce the requirements for the operator's operation skills,shorten the operation time,and reduce incidence of postoperative grade B and C pancreatic leakage.
