Clinical and surgical factors for successful stoma reversal in patients with Crohn's disease-results of a retrospective cohort study.

PURPOSE: Despite the wide range of medical and interventional therapy options available, some patients with Crohn's disease (CD) need an ileostomy or colostomy. The aim of this study was to identify clinical, surgical and drug-related predictors of successful stoma reversal in CD patients. METHODS: A retrospective medical record analysis of surgical department logs, hospital discharge letters and patient reports from outpatient departments was performed for all CD patients who underwent a first ostomy surgery. RESULTS: Our study analysed a total of 149 patients (76 women, 73 men, median age at first stoma of 34 years after a median CD duration of 9 years), with a median follow-up of 78.4 (IQR 88.6) months after first ostomy surgery. Of these patients, 73 (49%) underwent stoma reversal after a median of 11.7 months (IQR 15.7 months) of whom 17 (23.3%) needed a second stoma. In multivariant analysis, Montreal A1 classification (HR 2.07; 95% confidence interval 1.23-3.47; p = 0.006), a primary laparotomy (HR 2.30; 95% confidence interval 1.20-4.41; p = 0.012) and the absence of perianal/rectal CD activity (HR 3.00; 95% confidence interval 1.86-4.86; p < 0.001) emerged as independent predictors of a shorter time to stoma reversal. Introduction or switch of biological therapy after first stoma was not associated with successful reversal of the stoma (OR 4.6 95% confidence interval 1.45-14.66; p = 0.01). Laboratory parameters had no influence. CONCLUSION: Clinical and surgical features-rather than medication or laboratory findings-were found to be predictors of successful stoma reversal in CD patients. Future studies focusing on the definition of a Standard Operation Procedure for emergency and elective CD surgery are warranted.

The High-Resolution Three-Dimensional Magnetic Detector System 3D-Magma Accurately Measures Gastric and Small Bowel Motility in People with Type 2 Diabetes with Neuropathy.

Gastroparesis is an important complication of diabetes. Motility disorders are underdiagnosed and can lead to unexplained hypoglycemia. Currently diagnostic options are limited. All established methods harbor certain disadvantages. The 3D-MAGMA system is capable of reliably measuring gastric and small intestinal motility. The aim of the current study was to determine if 3D-MAGMA is able to detect changes in intestinal motility in people with type 2 diabetes. 18 healthy volunteers and 19 people with type 2 diabetes underwent motility testing by 3D-MAGMA. In the control group the retention time in the stomach was 33.0 [min] compared to 75.3 [min] in the diabetes group. The median time in the duodenum was 12.7 [min] compared to 8.1 [min]. The time for the first 50 cm of the jejunum was 29.9 [min] compared to 28.2 [min]. Discussion and conclusion: 3D-MAGMA is able to detect changes in intestinal motility. Its clinical value might be useful in patients with fluctuating blood glucose levels and unexplained hypoglycemic episodes.

Gastric dysmotility in Parkinson's disease is not caused by alterations of the gastric pacemaker cells.

The enteric nervous system is involved in the pathology of Parkinson´s disease and patients frequently have symptoms related to delayed gastric emptying. However, the pathophysiology of gastric dysmotility is yet not well understood. The objective of this study was to assess interdigestive gastric motility in Parkinson´s disease. Using an electromagnetic capsule system, the dominant gastric contraction frequency (primary outcome measure) and the gastric transit time were assessed in 16 patients with Parkinson´s disease and 15 young healthy controls after a fasting period of 8 h. Motor and non-motor symptoms were assessed using the Movement Disorder Society Unified Parkinson´s Disease Rating Scale III (MDS-UPDRS III), the Non-Motor Symptoms Questionnaire (NMS-Quest), and Hoehn & Yahr staging. The Gastroparesis Cardinal Symptom Index was used to record symptoms related to delayed gastric emptying. In healthy controls and patients with Parkinson's disease, the dominant contraction frequency was 3.0 cpm indicating normal function of interstitial cells of Cajal. In patients with Parkinson's disease, the gastric transit time was longer than in younger controls (56 vs. 21 min). The dominant contraction frequency and gastric transit time did not correlate with age, disease duration, Hoehn & Yahr stage, levodopa equivalent daily dose, MDS-UPDRS III, NMS-Quest, and Gastroparesis Cardinal Symptom Index. Changes of gastric motility in Parkinson´s disease are not caused by functional deficits of the gastric pacemaker cells, the interstitial cells of Cajal. Therefore, gastroparesis in Parkinson's disease can be attributed to disturbances in neurohumoral signals via the vagus nerve and myenteric plexus.
