(HealthDay)—For most patients with chronic pancreatitis (CP), optimized medical and interventional treatment is associated with significant pain relief, according to a study published online Jan. 4 in the Journal of Gastroenterology and Hepatology.

For the study, researchers from the All India Institute of Medical Sciences in New Delhi enrolled 313 consecutive with CP (92 percent with abdominal pain) who were treated with a well-balanced diet, pancreatic enzymes, and antioxidants. If failed, patients were offered endoscopic therapy and/or surgery.

The researchers found that the etiology of CP was idiopathic in 71.6 percent of the patients and alcohol in 26.2 percent. Significant pain relief was achieved at one-year follow-up in 84.7 percent of patients: 52.1, 16.7, 7.6, and 8.3 percent, respectively, with medical therapy, , surgery, and spontaneously. There was a significant decrease in the mean pain score, from 6.36 ± 1.92 to 1.62 ± 2.1. Among the 261, 218, 112, and 51 patients with followed up for three, five, 10, and 15 years, 54, 57.3, 60.7, and 68.8 percent, respectively, became pain-free at follow-up.

"Significant pain relief is achieved in the majority of patients with optimized medical and interventional treatment," the authors write.
