Background: The interim analysis of a prospective multicentre observational study of selective neoadjuvant chemoradiotherapy (OCUM) in patients with rectal cancer should evaluate the quality of diagnosis and therapy as a prerequisite for continuation of the study., Patients and Methods: 230 patients with the clinical stage cT2 - 4, each cN, M0 with radical tumour resection were enrolled until now. The values of 13 quality indicators were compared with the target values formulated by the workflow of the Working Group rectal cancer II and the German Cancer Society and were also compared with the results of the certified bowel centres of Germany 2010., Results: The target values were fulfilled to a high degree regardless of caseload. 83 % of parameters have been fully achieved and 14 % nearly achieved. In primary surgery the proportion of patients with 12 or more histologically examined lymph nodes was 99.2 %, after neoadjuvant chemoradiotherapy 90 %. A R0 resection was performed in 98.3 % and a resection of TME in muscularis propria plane only in 2.2 %. The rate of positive circumferential resection margins (pCRM + ) was 5.7 % only., Conclusions: The high quality of rectal surgery justifies the concept and the continuation of the study., (© Georg Thieme Verlag KG Stuttgart · New York.)

Purpose: To study the accuracy of different cutoffs for an involved circumferential resection margin (CRM) compared with T and N categories measured by MRI as basis for selective application of neoadjuvant radiochemotherapy (nRCT) in rectal carcinoma., Materials and Methods: In a prospective multicenter observational study involving 153 primarily operated patients, the preoperative results of MRI with pathohistological findings of resected specimens were compared., Results: For a cutoff of ≤1 mm for involvement of the CRM, the accuracy of preoperative MRI was 90.9% (139/153). The negative predictive value was 98.5% (134/136). The four participating departments did not differ significantly. For a cutoff of >2 mm and >5 mm, the rates of false-positive findings increased significantly from 5% to 12% and 35% with a decrease in accuracy to 82% and 62%, respectively. In contrast, the accuracy in predicting T (69.3%) and N categories (61.4%) was much lower., Conclusion: The indication for nRCT should be based on the determination of the minimal distance of the tumor from mesorectal fascia with a cutoff point of >1 mm as measured by MRI., (Copyright © 2013 Wiley Periodicals, Inc.)

Objective: Assaults by burning occur infrequently and are related to the social circumstances and demographics of each population. We aimed to explore the mechanisms, complications, morbidity and mortality associated with assault burn injuries admitted to the Burns Intensive Care Unit of Merheim University Hospital in Cologne., Methods: A retrospective data analysis of a consecutive series of 1 243 burn patients between 1989 and 2004. The cohort was divided into two groups: AG (assault group) and CG (control group). Analyses were controlled for clinical data, treatment and outcome of all patients involved., Results: Forty-one patients with assault burn injuries were identified during the study period. Compared with the general burn population (CG), the AG had a significantly larger size of third-degree burns (p=0.047), a higher incidence of inhalation injury (p<0.001) and a longer intubation period (p=0.047). Patients in the AG were also more likely to undergo escharotomy (p=0.013) and to receive antibiotics on admission (p=0.016). The mortality rate was higher in the AG than in the CG (26.8% v. 19.9%), but this difference was not significant., Conclusions: Burned patients who were victims of assault tend to have more severe injuries than the general burn population. These injuries are not only physical, and their management requires a multidisciplinary approach to improve outcome.

Self-immolation constitutes a rare form of suicide in developed countries, though it accounts for unique injury characteristics in the burn intensive care unit. The aim of this study was to present the epidemiological and clinical features of patients burned during a suicidal attempt seen in a North Rhine-Westphalia burn intensive care unit (BICU). To address this aim, we undertook a 21-year retrospective study involving patients with thermal injuries admitted to the largest burn unit in Germany. A total of 125 suicide-related burn victims were identified in the study period (9.4%). Comparing the self-immolation group with the rest burn patient cohort, suicide victims were more likely to be single and to act under the influence of alcohol. The suicidal group had a larger extent of burns, higher incidence of inhalation injury, required more surgical procedures, catecholamines, blood transfusions, and a longer BICU stay. Their clinical course was complicated by prolonged intubation period, higher rate of multiple drug-resistant bacteria acquisition and sepsis, leading to a higher mortality rate. Although the proportion of self-immolation victims among all burned patients is not high, the markedly higher severity of their burns and their poorer quality of outcomes makes them an important clinical subgroup for further study.

Objective: To evaluate demographic and socioeconomic factors associated with assault burn injuries., Background: Assault by burning demonstrates a rare but severe public health issue and accounts for unique injury characteristics in the burn intensive care unit (BICU)., Methods: We conducted a retrospective cohort study involving patients with thermal injuries admitted to the BICU of a university hospital. The patient cohort was divided into two groups (ABI group: patients with assault burns, n=41;, Control Group: population of all other burned patients admitted to the BICU, n=1202). Bivariate and multivariate analyses including demographic and socioeconomic data were used to identify factors associated with assault burns., Results: Forty-one assault-related burn victims were identified in the study period. This represents 3.3% of all significant burns admitted. Comparing battery victims with the control population, assault patients were more likely to be young (mean age 36.2 years vs. 42.2 years) and immigrants (41.5% vs. 15.1%). Furthermore, marital status (65.9% vs. 40.8% singles), employment status (36.6% vs. 9.7% unemployed) and insurance status (41.5% vs. 12.3% social insurance) were significantly different in the bivariate analysis. Logistic regression evaluation identified three variables that were independently associated with assault burns: younger age (< or =25 years) (odds ratio, 2.54 [95% confidence interval, 1.29-5.02]; p=0.007), ethnic minority (odds ratio, 3.71 [95% confidence interval, 1.91-7.20]; p<0.001) and unemployment (odds ratio, 4.02 [95% confidence interval, 2.03-7.97]; p<0.001)., Conclusions: The high incidence of youngsters, unemployment and the great proportion of immigrants in victims of assault might provide several opportunities for community-based psychosocial and occupational programs. A multidisciplinary approach targeting issues specific to the violent nature of the injury and the socioeconomic background of the victims may be of benefit to improve their perspectives for rehabilitation.

Introduction: Complications of gastroduodenal ulcers such as bleeding and perforation have been afflicted with a mortality of up to 40 % in the past. Altered ulcer manifestation by improvement of medical treatment as well as advances in surgical techniques and intensive care medicine might currently have improved the outcome of these severely ill patients., Patients and Methods: A retrospective analysis of 73 patients with emergency operation for bleeding or perforated gastric (n = 50) and duodenal ulcer (n = 23) between 10/1994 and 7/2001 was performed., Results: The median age was 58 years (17-90 years) with 30 % of patients exceeding the age of 70 years. Eighty-one percent of patients had perforation, 19 % had bleeding. Factors predisposing for gastroduodenal ulcers were present in 88 %. Five percent of gastric perforations were due to gastric malignancies. Diagnosis of perforation was made in 88 % by conventional X-rays, in 12 % of perforations no free abdominal gas was detectable. A local surgical procedure (excision of ulcer and sutures/pyloroplasty) was performed in 64/73 patients (88 %), partial gastroduodenal resection was necessary in 9 patients (12 %). Histologic examination for helicobacter pylori was positive in 30/39 specimens (77 %). In-hospital mortality was 14 %, both for patients with bleeding and perforated ulcers. Surgical complications were 12 %., Discussion: Altered ulcer manifestation, minimized surgical therapy and improved intensive care medicine led to a recent reduction in postoperative mortality of patients suffering from perforated or bleeding gastroduodenal ulcer. A further reduction of this still high mortality might be expected by improvement of surgical training and/or restriction of therapy to a limited number of surgeons.

Background and Aims: Small bowel obstruction is a disease the surgeon frequently is confronted with. In the present study the records of the patients (n = 202) with mechanical obstruction of the small intestine from the last four years were analysed and the results are critically compared with the literature., Methods: In the reported retrospective study the length of patient's history, the cause of bowel obstruction, the preoperative examinations performed, the kind of surgical intervention and the postoperative management and outcome were investigated., Results: The average patient's age was 62 years, the mean preoperative duration of symptoms was 6.5 days. 77% of the patients had underwent abdominal surgery prior to the obstruction. Conventional x-ray was performed in 92%, gastrographin passage in 46% and CT-scan in 23% of the cases. The average length of hospitalisation was 12 days. The overall postoperative morbidity was 21%, the mortality 2.5%., Conclusion: It could be shown that patient's history, clinical symptoms and conventional x-rays of the abdomen are sufficient for the indication of surgical intervention. In uncertain cases the examination of the passage with contrast medium is recommended. The surgical results of small bowel obstruction management have significantly improved over the past decades, today's mortality is lower than 5%.
