Can round ligament of the liver patch decrease the rate and the grade of postoperative pancreatic fistula?
Languages of publication
The most serious complication after pancreatic surgical procedures is still a postoperative pancreatic fistula. In clinical practice there are various methods to prevent the formation of pancreatic fistula, but none of them is fully efficient. Recently, the role of grafting the round ligament of the liver on the pancreas is emphasized as a promising procedure which reduces the severity and shortens the healing time of postoperative pancreatic fistula. The aim of the study was to assess the impact of grafting a round ligament patch on the pancreatic stump or the area of the pancreatic anastomosis on the severity and healing of pancreatic fistula after surgical treatment of the pancreas (alternatively on prevention of pancreatic fistula formation). Material and methods. The retrospective study covered patients operated due to pancreatic tumors in the Department of General, Gastrointestinal and Oncologic Surgery of the WUM. Pancreatic fistula was diagnosed according to the definition developed by the ISGPS (International Study Group of Pancreatic Surgery). Results. 10 patients with pancreatic tumors of different location were operated. The round ligament was grafted on the pancreatic stump, the area of the pancreatic anastomosis or on the site of the local tumor removal. Pancreatic fistula developed in 9 patients, including grade A pancreatic fistula in 5 patients, grade B fistula in 3 patients, and grade C fistula in 1 patient. Distant complications occurred in one patient. None of the patients required a reoperation and no deaths were reported. The average hospital stay was 22.4 days. The hospital stay of patients with grade A fistula was shorter than in case of patients with grade B and C fistula. Conclusions. Grafting of the round ligament of the liver on the pancreatic stump did not prevent the development pancreatic fistula. Grade A pancreatic fistula developed most often. Grade C fistula developed in 1 patient and was complicated by intraabdominal abscesses and sepsis. Although the patient did not require a repeated surgery, but only a continuation of conservative treatment on an outpatient basis. Patients with grade B fistula required prolonged drainage and in the end were supervised by the surgical polyclinic.
