Background
The prevalence and impact of chronic gastrointestinal dysmotility following total pancreactectomy with islet autotransplantation (TP-IAT) for chronic pancreatitis is not known.
Methods
A cross-sectional study of all patients who underwent TP-IAT at our institution from August 2011 to November 2015 was undertaken. The GCSI (Gastroparesis Cardinal Symptom Index), PAGI-SYM (Patient Assessment of Upper Gastrointestinal Disorders-Symptom Severity Index), PAC-SYM (Patient Assessment of Constipation Symptoms), Bristol stool chart, 12-item Short Form Health Survey (SF-12), and visual analog scale for pain were administered ≥4 weeks following TP-IAT.
Key Results
The prevalence of any dysmotility symptoms in patients who completed the survey (33/45, 73%) post-TP-IAT was 45%. Post-TP-IAT, the mean reduction in opioid dosing was 77.6 oral morphine equivalents (OMEs) (95% CI 32.1–123.0, p = 0.002) with 42% of patients requiring no opioids. There was significant negative correlation between dysmotility scores and SF-12 physical scores (r = −0.46, p = 0.008, 95% CI −0.70 to −0.13). Self-reported abdominal pain had significant negative correlation with both physical and mental SF-12 scores (r = −0.67, p < 0.001, 95% CI −0.83 to −0.41 and r = −0.39, p = 0.03, 95% CI −0.65 to −0.04). There was no correlation between gastrointestinal dysmotility and self-reported pain.
Conclusions and Inferences
Symptoms of chronic gastrointestinal dysmotility and chronic abdominal pain are common post-TP-IAT and will need to be better recognized and differentiated to improve the management of these patients.
