RESUMEN
BACKGROUND: This clinical trial explores the Sigstad score for late dumping syndrome in postoperative patients who have undergone sleeve gastrectomy (SG) or One Anastomosis Gastric Bypass (OAGB). The aims of this study are to investigate the correlations with late dumping syndrome, to evaluate the reliability and validity of the Sigstad score and to discuss a modified scoring system. METHODS: The study was conducted at the Obesity Center of the Westküstenklinikum Heide and included 271 patients. Data collection involved conducting interviews, diet diaries and measuring blood glucose levels. Non-parametric tests, logistic regression and McDonald's Omega were the selected statistical approaches. RESULTS: Body Mass Index (BMI) decreased over time (-9.67 kg/m2 at 4 months, -15.58 kg/m2 at 12 months). Preoperatively, the Sigstad score exhibited the highest value, and no occurrences of late dumping syndrome were observed. No significant differences were found in BMI concerning late dumping syndrome or Sigstad score among postoperative patients. Postoperative patients experienced an increase in gastrointestinal symptoms. The reliability test showed a McDonald's omega value of 0.509. The analysis conducted through binary logistic regression indicated dizziness as a significant predictor of late dumping syndrome; however, this finding did not hold up after performing Bonferroni correction. CONCLUSION: The Sigstad score is not a reliable or valid method for detecting late dumping syndrome after surgery for obesity and metabolic disorders. It is necessary to have alternatives that use objective measures and assess the quality of life, and that these alternatives be validated in large patient cohorts.

BACKGROUND AND PURPOSE: To assess the safety and effectiveness of treating high-risk T1 and T2 bladder cancer with transurethral resection (TUR-BT) followed by radiochemotherapy (RCT) combined with regional deep hyperthermia (RHT). MATERIAL AND METHODS: Between 2003 and 2007, 45 patients were enrolled. After TUR-BT patients received radiotherapy (RT) of the bladder and regional lymph nodes with 50.4 Gy, and a boost to the bladder of 5.4-9 Gy. RCT was applied to 43/45 patients. RHT was administered once weekly. Response was re-evaluated 6 weeks after RT by restaging-TUR. Toxicity was graded with the CTCAE, version 3.0. QoL was evaluated by a dedicated questionnaire. RESULTS: The median follow-up was 34 months (range 12-60). The median number of hyperthermia treatments was 5 (range 1-7). Acute toxicity grades 3 and 4 occurred in 20% (9/45) and 9% (4/45), respectively. Late toxicity grades 3/4 were seen in 24% (11/45). Complete response rate was 96% (43/45). Local recurrence-free survival was 85%, overall survival was 80%, disease-specific survival was 88%, metastasis-free survival was 89%, and the bladder-preserving rate was 96% (43/45) at 3 years. Eighty percent (24/30) were at least mostly satisfied with their bladder function. CONCLUSIONS: The quadrimodal treatment was feasible and well tolerated. Local control and bladder-preserving rates were encouraging.
