Unlabelled: Upper abdominal pain, a frequent symptom of the presence of gallstone disease, is the cause of 6% of the emergency calls of the Austrian emergency system. Pain resulting from cholelithiasis is characteristically severe. Recent data show that active warming during emergency transport of trauma victims is effective in reducing pain. Therefore, we hypothesized that local active warming of the abdomen would be an effective pain treatment for patients with acute cholelithiasis and could be provided by paramedics. Sixty patients (>19 yr) consented to participate in this study. They were divided into two groups: Group 1, who received active warming of the upper abdomen with a carbon-fiber warming blanket (42 degrees C), and Group 2, who received no warming of the abdomen. Neither group received any drug-based pain care. Patients were asked to rate their pain and anxiety by using visual analog scales (VAS). Statistical evaluation was performed with Student's t-test; P < 0.05 was considered significant. In Group 1, a significant (P < 0.01) pain reduction was recorded in all cases on a visual analog scale (VAS), from 86.8 +/- 5.5 mm to 41.2 +/- 16.2 mm. In Group 2, the patients' pain scores remained comparable, from 88.3 +/- 9.9 mm to 88.1 +/- 10.0 mm on a VAS. In comparing Group 1 with Group 2 on arrival at the hospital, pain scores showed a significant difference (P < 0.01). In Group 1, the VAS score changes for anxiety were significantly reduced (P < 0.01), from 82.7 +/- 10.8 mm before treatment to 39.0 +/- 14.0 mm after treatment. In Group 2, a nonsignificant change of this score was noted, from 84.5 +/- 14.6 mm to 83.5 +/- 8.4 mm. Comparing Group 1 with Group 2 on arrival at the hospital showed a significant difference in anxiety scores (P < 0.01). We conclude that local active warming is an effective and easy-to-learn treatment for pain resulting from acute cholelithiasis in emergency care., Implications: Active local warming of the upper abdomen is an effective treatment for patients with cholelithiasis being transported to the hospital by paramedics who are not permitted to provide any drug-based pain care. We observed no negative side effects of this treatment.

This paper presents clinical data elucidating the natural history of gall stone disease, based on observations carried out on a secluded alpine population treated conservatively for generations. Special circumstances corroborating a statistical evaluation are outlined. Pertinent parameters supporting this study are anatomical findings at operation following the introduction of established surgical procedures into the region, with particular attention to age grouping within the collectives of patients. A total of 130 patients, operated on for gall stones for the first time in their lives, were evaluated, 18 patients undergoing incidental cholecystectomy for asymptomatic gall stones were excluded from this series. Of the remaining collective presenting with clinical symptoms of cholelithiasis, 54% were admitted for complications of the disease, i.e. 15% for acute cholecystitis and 39% for choledocholithiasis (including jaundice in 27%). We conclude that the natural history of gall stone disease in this region implicates the incidence of the above-mentioned inherent complications unless cured electively by early cholecystectomy.
