The panc 3 score: a rapid and accurate test for predicting severity on presentation in acute pancreatitis.

Goal The goal of our study was to develop a simple rule that could rapidly identify those at risk for severe acute pancreatitis (SAP) in the ER. Methods We identified all published studies reporting risk factors for SAP. We identified 3 risk factors which had been shown to predict SAP. The risk factors we identified were a serum hematocrit greater than 44 mg/dL, a body mass index (BMI) greater than 30 mg/kg2, and a chest x-ray which reveals a pleural effusion (Panc 3 criteria). We computed the test-operating characteristics and likelihood ratios for each risk factor using the patients originally sampled in each of the studies (n=393). For validation, we examined Panc 3s ability to predict SAP in patients seen at our medical center [University of North Carolina at Chapel Hill (UNC) hospitals n=238]. Results The likelihood ratios positive and negative for HCT, BMI>30 kg/M2, and a chest x-ray with a pleural effusion were 14, 9.8, and 8.7, respectively, for the original data and 178, 2.4, and 1.3 for the UNC data. Sensitivity analysis revealed satisfaction of the HCT, BMI, and pleural effusion criteria had a posttest likelihood of disease 99% when the pretest probability of disease varied from 12-25%. These values were true for the original and UNC data. Conclusions The Panc 3 score is easy to use and accurate for the prediction of SAP. The serum HCT was the strongest predictor of SAP. The combination of the Panc 3 variables was highly predictive of SAP.

Age and Dyssynergia Subtypes Associated With Normal Sphincter Pressures in Women With Fecal Incontinence

Objectives Fecal incontinence (FI) is frequently associated with low sphincter pressures, sensory abnormalities, and advanced age. Twenty-three percent of patients with FI and 22% of healthy patients demonstrate dyssynergic defecation (DD) on high-resolution anorectal manometry. Overflow incontinence occurs in some DD patients with normal resting and squeeze anal sphincter pressures. Our aim was to identify factors associated with normal sphincter pressures in women with FI. Methods We reviewed medical records of 134 women with FI. Patients with normal resting and squeeze anal pressures were compared with those with abnormal pressures using Wilcoxon rank sum test and Fisher exact. Multivariable logistic regression was performed to identify factors associated with normal resting and squeeze anal pressures. Results Among 134 women, abnormal resting and/or squeeze pressures were identified in 113 and normal pressures were identified in 21. Women with normal sphincter pressures were younger (mean age 52.7 ± 10.8 years vs 59.0 ± 14.0 years, P = 0.036), more often had abnormal defecation indices (100% vs 83.2%, P = 0.043) and higher rectal defecation pressures (30.8 ± 18.8 mm Hg vs 50.8 ± 22.6 mm Hg, P < 0.001). There was an overall association between DD subtype and normal and abnormal sphincter pressure groups (P = 0.021). Dyssynergia subtypes I or III (odds ratio, 7.2; 95% confidence interval, 1.8–28.8) and age younger than 67 years (odds ratio, 8.5; 95% confidence interval, 1.5–48.6) were associated with greater odds of having normal sphincter pressures. Conclusions Female FI patients with normal anal sphincter pressures are younger, have higher rectal defecation pressures, and more often have type I or type III DD.

Use of Sacral Nerve Stimulation for the Treatment of Overlapping Constipation and Fecal Incontinence

Patient: Female, 51 Final Diagnosis: Fecal incontinence Symptoms: Constipation • fecal incontinence Medication: — Clinical Procedure: Sacral nerve stimulator Specialty: Gastroenterology and Hepatology Objective: Rare co-existance of disease or pathology Background: Fecal incontinence and constipation are common gastrointestinal complaints, but rarely occur concurrently. Management of these seemingly paradoxical processes is challenging, as treatment of one symptom may exacerbate the other. Case Report: A 51-year-old female with lifelong neurogenic bladder secondary to spina bifida occulta presented with progressive symptoms of daily urge fecal incontinence as well as hard bowel movements associated with straining and a sensation of incomplete evacuation requiring manual disimpaction. Pelvic floor testing showed poor ability to squeeze the anal sphincter, which indicated sphincter weakness as a major contributor to her fecal incontinence symptoms. Additionally, on defecography she was unable to widen her posterior anorectal angle or relax the anal sphincter during defecation consistent with dyssynergic defecation. A sacral nerve stimulator was placed for management of her fecal incontinence. Interestingly, her constipation also dramatically improved with sacral neuromodulation. Conclusions: This unique case highlights the emerging role of sacral nerve stimulation in the treatment of complex pelvic floor dysfunction with improvement in symptoms beyond fecal incontinence in a patient with dyssynergic-type constipation.
