Health-related Quality of Life and Functional Outcomes in 5-year Survivors After Pancreaticoduodenectomy.

OBJECTIVE: Our aim was to assess quality of life (QOL) and functionality in a large cohort of patients ≥5-years after pancreaticoduodenectomy (PD). BACKGROUND: Long-term QOL outcomes after PD for benign or malignant disease are largely undocumented. METHODS: We administered the EORTC QLQ-C30 questionnaire to patients who underwent PD for neoplasms from 1998 to 2011 and compared their scores with an age- and sex-matched normal population. Clinical relevance (CR) of differences was scored as small (5-10), moderate (10-20), or large (>20) based on validated interpretation of clinically important differences. RESULTS: Of 305 PD survivors, 245 (80.3%) responded, of whom 157 (64.1%) underwent PD for nonmalignant lesions. Median follow-up was 9.1 years (range 5.1 -21.2 yrs). New-onset diabetes developed in 10.6%; 50.4% reported taking pancreatic enzymes; 54.6% reported needing antacids. Compared with the age- and sex-adjusted controls, PD survivors demonstrated higher global QOL (78.7 vs 69.7, CR small, P < 0.001), physical (86.7 vs 77.9, CR small, P < 0.001) and role-functioning scores (86.3 vs 74.1, CR medium, P < 0.001). Using linear regression and adjusting for socioeconomic variables, there were no differences in QOL or functional scores in the benign versus malignant subgroups. Older age at operation was associated with worse physical-functioning (-0.4/yr, P = 0.008). Taking pancrelipase (-6.8, P = 0.035) or antacids (-6.3, P = 0.044) were both associated with lower social-functioning scores. CONCLUSIONS: Patients who had a PD demonstrated better global QOL, physical- and role-functioning scores at 5-years when compared with age- and sex-matched controls. Approximately half of the patients required pancreatic enzyme replacement, while only 11% developed new-onset diabetes.

Assessment of the learning curve for pancreaticoduodenectomy.

BACKGROUND: Experience with the Whipple procedure has been associated with improved outcomes, but the learning curve for this complex procedure is not well defined. METHODS: Outcomes with 162 consecutive Whipple procedures during the 1st 11.5 years of practice was documented in a prospective database. A period of low (≤11/y) and high (≥23/y) case volume was compared using the Wilcoxon rank-sum test and Fisher exact test. RESULTS: With low case volume, blood loss was higher (800 vs 400 mL, P = .001), more patients were transfused (44% vs 18%, P = .027), there were more complications (58% vs 46%, P = .0337), and a longer length of stay (10 vs 7 days, P = .006). There was only 1 mortality (.7%). CONCLUSIONS: Frequent repetition of the Whipple procedure is associated with an improvement in quantifiable quality benchmarks, and improvement continues with extensive experience. However, with proper training and the right environment, this procedure can be performed during the learning curve with acceptable outcomes.

Pancreaticoduodenectomy with pancreaticogastrostomy: assessment of patients' nutritional status, quality of life and pancreatic exocrine function.

BACKGROUND: The changes in digestive function of patients with pancreaticoduodenectomy (PD) and pancreaticogastrostomy reconstruction have not been well-documented. The present study sought to assess the nutritional status, quality of life and pancreatic exocrine function in this group of patients. METHODS: The study group consisted of 11 PD with pancreaticogastrostomy patients. The control group consisted of 11 consecutive patients who had subtotal gastrectomy (SG) for distal stomach tumours. RESULTS: The median ages for the PD and SG groups were 57 and 59 years, respectively. The median intervals between surgery to assessment were 68 and 60 weeks, respectively. The PD group attained a mean of 92.7% of their pre-surgery weight compared to 91.3% in the SG group. Both groups had a comparable gastrointestinal quality of life index and Visick scale scores. Exocrine insufficiency using the faecal chymotrypsin test was present in 36% of patients with PD. None of the patients in the SG group had exocrine insufficiency. CONCLUSION: Pancreaticoduodenectomy patients had a significant occurrence of pancreatic exocrine insufficiency compared to the SG group. But patients with PD and pancreaticogastrostomy reconstruction maintained a nutritional status and quality of life similar to those with curative SG for stomach malignancy. Apart from exocrine insufficiency, the concomitant gastrectomy in the PD group is an important factor responsible for their inability to gain weight.
