Factors associated with recidivism following pancreaticoduodenectomy.

Objectives: Factors related to readmission after pancreaticoduodenectomy (PD) may include postoperative morbidity and the functional status of the patient. This study aimed to retrospectively review our institution's experience of readmission of patients who had undergone Whipple procedure PD.

Methods: Recidivism was defined as readmission to the primary or a secondary hospital within, respectively, 30 days, 30-90 days or 90 days postoperatively. Associations between recidivism, perioperative factors and patient characteristics were evaluated.

Results: During the past 5 years, 30-day, 30-90-day and 90-day recidivism rates were 14.5%, 18.5% and 27.4%, respectively. The most common reasons for readmission included dehydration and/or malnutrition (37.5% of readmissions) and pain (12.5%). Patients who underwent PD for chronic pancreatitis were more likely to be readmitted within 90 days of surgery than patients who underwent PD for malignancy (P < 0.01). Intraoperative transfusion was also associated with 30-90-day and 90-day recidivism (P < 0.01). Preoperative comorbidities, including Charlson Comorbidity Index score, number of pre-discharge complications, type of Whipple reconstruction, preoperative biliary stenting, need for vascular reconstruction and patient body mass index were not associated with recidivism.

Conclusions: Our data confirm previous reports indicating high rates of readmission after PD. To our knowledge, this report is the first to demonstrate chronic pancreatitis as an independent risk factor for readmission.
