THE DEPENDENCE OF DIRECT RESULTS OF DISTAL PANCREATECTOMIES ON DIFFERENT PANCREATIC STUMP CLOSURE TECHNIQUES

Abstract

The  OBJECTIVE  is  to  study  the  effect  of application of different  pancreatic stump  closure techniques to  the  postoperative period,  the frequency and  severity  of postoperative complications including postoperative pancreatic fistulas  after distal pancreatectomies. MATERIAL AND METHODS.  The  clinical  material  consisted of 126  patients who  underwent distal  pancreatectomies  (isolated or  in  combination  with  surgical   interventions  on  the  adjacent organs of  the  abdominal cavity  and retroperitoneal space).  The  patients  were   divided  into  4  groups  depending  on  the  pancreatic  stump   closure  techniques (isolated suturing  of the  main  pancreatic duct  of the  pancreatic stump  with its omentization by gastrocolic omentum or local sealing its  by  hemostatic sponge  (control  group);  using  a  local  biological  glue  2-octylcyanoacrylate; using  the  Endoscopic Linear  Cutter  Echelon; external transduodenal  transnasal  drainage of the  enlarged main  pancreatic duct  of the  pancreatic stump). We  evaluated the  influence   of  different  pancreatic stump   closure techniques  after  distal  pancreatectomies on  the postoperative period  as well the  frequency and  severity  of postoperative pancreatic fistulas  depending on the  diameter of the main  pancreatic duct  of pancreatic stump.   RESULTS.  The  overall  rate  of postoperative  complications in the  control  group of patients was  45.8  %, and  was  due  to an  increase in the  frequency of specific  complications (35.4  %). The  most  frequent complication  in  the  control  group   of  patients  was   postoperative  pancreatic  fistulas   –  29.2   %.  The  statistically   significant decrease  of  frequency  and   severity   of  postoperative  complications,  frequency  and   severity   of  postoperative  pancreatic fistulas and decrease of postoperative hospital-stay after the application of the proposed different pancreatic stump closure techniques were  revealed in comparison with the  control  group  of patients. There  was  no  hospital  mortality.  CONCLUSION. Distal  pancreatectomy with  «standard»  pancreatic stump   closure techniques  accompanied by  high  frequency and  severity of postoperative complications, as well as postoperative pancreatic fistulas. The use of the proposed pancreatic stump closure techniques after  distal  pancreatectomy led  to  a  decrease of  the  frequency and  severity   of  postoperative  complications, a decrease of the  frequency and  severity  of postoperative pancreatic fistulas,  and  a decrease of the  postoperative hospital-stay.
