Objective: This study evaluated the incidence of postoperative morbidities, focusing specifically on pancreatic fistulas, after a splenectomy performed as part of cytoreductive surgery for the treatment of ovarian cancer.
Methods: A retrospective chart review was performed for all the patients with ovarian, tubal, or peritoneal cancer who underwent splenectomy during a 5-year period. Patient-, disease-, and surgery-related data were collected. Pancreatic fistulas were identified when the drainage fluid obtained via a surgically placed drain had an amylase content greater than 3 times the normal serum value after postoperative day 3.
Results: A splenectomy was performed in 21 patients. Postoperative pancreatic fistulas developed in 6 patients (29%). Of these 6 patients, 2 had no symptoms and did not require specific treatment for their pancreatic fistulas. Therapeutic intervention was required in the remaining 4 patients. The durations of oral feeding prohibition and the use of a peripancreatic drain were longer in the patients with a pancreatic fistula than in those without a pancreatic fistula. Overall, the pancreatic fistulas were managed conservatively or using minimally invasive procedures. Staple-line reinforcement seemed to be an effective means of closing the transected stump during the splenectomy, compared with the standard stapling technique.
Conclusions: Elevated amylase levels in the drainage fluid reflect the patient's actual condition better than serum amylase levels. We recommend the intraoperative placement of a peripancreatic drain and postoperative measurement of amylase concentrations in the drainage fluid to identify the development of pancreatic fistulas and to facilitate the management of this complication.
