BACKGROUND: The absence of surgical complications has traditionally been used to define successful recovery after pancreas surgery. However, patient-reported outcome measures as metrics of a challenging recovery may be superior to objective morbidity. This study aims to evaluate the use of patient-reported outcomes in assessing recovery after pancreas surgery.
METHODS: Patients scheduled for pancreatoduodenectomy were prospectively enrolled between 2016 to 2018. Patient-reported outcomes were collected using the linear analog self-assessment questionnaire preoperatively and on postoperative days 2, 7, 14, 30, and monthly until 6 months. Patients were also asked if they felt fully recovered at 30 days and 6 months. Thirty-day surgical morbidity was prospectively assessed, and the comprehensive complication index at 30 days was used to categorize morbidity as major or multiple minor complications (comprehensive complication index ≥26.2) vs uncomplicated (comprehensive complication index <26.2). Clinically significant International Study Group Pancreas Surgery Grade B and C pancreatic fistulas and delayed gastric emptying were reported. χ2 and Kruskal-Wallis tests were used to assess associations with recovery by 6 months and quality of life throughout the postoperative period.
RESULTS: Of 116 patients who met inclusion criteria and were enrolled, 32 (28%) had major or multiple minor complications (comprehensive complication index ≥26.2). Overall, fewer than 1 in 10 patients (7%) reported feeling fully recovered at 30 days postoperatively, whereas 55% reported feeling fully recovered at 6 months. Of patients suffering major morbidity, 62% did not recover by 6 months, whereas 38% of those in the uncomplicated group reported not being recovered at 6 months (P = .03). Patients who experienced delayed gastric emptying reported low quality-of-life scores at 1 month (P = .04) compared to those with no delayed gastric emptying, but this did not persist at 6 months (P = .80). Postoperative pancreatic fistula was not associated with quality of life at 1 or 6 months (both P > .05). In the uncomplicated patients, age, sex, surgical approach, and cancer status were not associated with failed recovery at 6 months (all P > .05), and healthier patients (American Society of Anesthesiologists 1-2) were less likely to report complete recovery (42% vs 69% American Society of Anesthesiologists 3-4, P = .04). With the exception of higher preoperative pain scores (mean 2.3 [standard deviation 2.4] among patients not fully recovered at 6 months vs 1.6 [2.2] among those fully recovered, P = .04), preoperative patient-reported outcomes were not associated with failed recovery at 6 months (all P > .05). However, lower 30-day quality of life, social activity, pain, and fatigue scores were associated with incomplete recovery at 6 months.
CONCLUSION: More than 1 in 3 patients with an uncomplicated course do not feel fully recovered from pancreas surgery at 6 months; the presence of surgical complications did not universally correspond with recovery failure. In patients with complications, delayed gastric emptying appears to drive quality of life more significantly than postoperative pancreatic fistula. In patients with uncomplicated recovery, healthier patients were less likely to report full recovery at 6 months. Thirty-day patient-reported outcomes may be able to identify patients who are at risk of incomplete long-term recovery.
