Background: Complete mesocolic excision (CME) for right colonic cancer is a more complex operation than standard right hemicolectomy but evidence to support its routine use is still limited. This prospective multicentre study evaluated the effect of CME on long-term survival in colorectal cancer centres in Germany (RESECTAT trial). The primary hypothesis was that 5-year disease-free survival would be higher after CME than non-CME surgery. A secondary hypothesis was that there would be improved survival of patients with a mesenteric area greater than 15 000 mm2. Methods: Centres were asked to continue their current surgical practices. The surgery was classified as CME if the superior mesenteric vein was dissected; otherwise it was assumed that no CME had been performed. All specimens were shipped to one institution for pathological analysis and documentation. Clinical data were recorded in an established registry for quality assurance. The primary endpoint was 5-year overall survival for stages I-III. Multivariable adjustment for group allocation was planned. Using a primary hypothesis of an increase in disease-free survival from 60 to 70 per cent, a sample size of 662 patients was calculated with a 50 per cent anticipated drop-out rate. Results: A total of 1004 patients from 53 centres were recruited for the final analysis (496 CME, 508 no CME). Most operations (88.4 per cent) were done by an open approach. Anastomotic leak occurred in 3.4 per cent in the CME and 1.8 per cent in the non-CME group. There were slightly more lymph nodes found in CME than non-CME specimens (mean 55.6 and 50.4 respectively). Positive central mesenteric nodes were detected more in non-CME than CME specimens (5.9 versus 4.0 per cent). One-fifth of patients had died at the time of study with recorded recurrences (63, 6.3 per cent), too few to calculate disease-free survival (the original primary outcome), so overall survival (not disease-specific) results are presented. Short-term and overall survival were similar in the CME and non-CME groups. Adjusted Cox regression indicated a possible benefit for overall survival with CME in stage III disease (HR 0.52, 95 per cent c.i. 0.31 to 0.85; P=0.010) but less so for disease-free survival (HR 0.66; P= 0.068). The secondary outcome (15 000 mm2 mesenteric size) did not influence survival at any stage (removal of more mesentery did not alter survival). Conclusion: No general benefit of CME could be established. The observation of better overall survival in stage III on unplanned exploratory analysis is of uncertain significance.

Background: In some areas of Germany, there is a shortage of specialist physicians for patients with inflammatory rheumatic diseases. Delegating certain medical care services to qualified, specialized rheumatological assistants (SRAs) might be an effective way to supplement the available capacity for specialized medical care. Methods: Patients under stable treatment for rheumatoid arthritis (RA) or psoriatic arthritis (PsA) were included in this trial, which was designed to demonstrate, in a first step, the non-inferiority of a form of care involving delegation of physicians' tasks to SRAs (team-based care), in comparison to standard care, with respect to changes in disease activity at one year. "Non-inferiority," in this context, means either superiority or else an irrelevant extent of inferiority. In a second step, in case non-inferiority could be shown, the superiority of team-based care with respect to changes in patients' health-related quality of life would be tested as well. Disease activity was measured with the Disease Activity Score 28, and health-related quality of life with the EQ-5D-5L. This was a randomized, multicenter, rater-blinded trial with two treatment arms (team-based care and standard care). The statistical analysis was performed with mixed linear models (DRKS00015526). Results: From September 2018 to June 2019, 601 patients from 14 rheumatological practices and 3 outpatient rheumatological clinics in the German states of North Rhine--Westphalia and Lower Saxony were randomized to either team-based or standard care. Team-based care was found to be non-inferior to standard care with respect to changes in disease activity (adjusted difference = -0.19; 95% confidence interval [-0.36; -0.02]; p <0.001 for non-inferiority). Superiority with respect to health-related quality of life was not demonstrated (adjusted difference = 0.02 [-0.02; 0.05], p = 0.285). Conclusion: Team-based care, with greater integration of SRAs, is just as good as standard care in important respects. Trained SRAs can effectively support rheumatologists in the care of stable patients with RA or PsA. [ABSTRACT FROM AUTHOR]

- Abstract
Robot-assisted systems have been increasingly used in general surgery for several years. Accordingly, the number of systems installed in Germany has also rapidly increased. While around 100 robot-assisted systems were used in German hospitals in 2018, this figure had already risen to more than 200 by 2022. The aim of this article is to present the current state of development and trends in robotic surgery in Germany. For this purpose, data from the StuDoQ|Robotics register were analyzed. Furthermore, a descriptive analysis of concomitant diagnosis-related groups (DRG) data was carried out via the Federal Statistical Office (Destatis), for a better assessment of the representativeness of the StuDoQ|Robotics register data. In both data sets, the annual number of robot-assisted visceral surgery procedures in Germany steadily increased. Compared to the DRG data, only 3.7% up to a maximum of 36.7% of all robot-assisted procedures performed were documented in the StuDoQ|Robotics register, depending on the type of procedure. Colorectal resections were the most frequent robot-assisted procedures (StuDoQ: 32.5% and 36.7% vs. DRG data: 24.2% and 29.7%) and had, for example, low mortality rates (StuDoQ: 1% and 1% vs. DRG data: 2.3% and 1.3%). Due to the low coverage rates of robot-assisted esophageal, gastric, pancreatic and liver interventions, no valid statements could be derived from the StuDoQ data for these areas. With the current coverage rates, the informative value of the StuDoQ|Robotics register is considerably limited for some types of intervention. In the future, measures should therefore be explored that lead to a significant increase in the coverage rates., (© 2023. The Author(s).)

- Abstract
Introduction: The demographic trend will lead to an increase of elderly persons in Germany in the future. The population is becoming smaller and older because of the deficiency in childbirths. This results in demographic ageing of the population in Germany. Studies addressing patients ≥ 85 years, the oldest old, are becoming more and more important., Materials and Methods: The prospectively collected data of 141 patients ≥ 85 years with colorectal carcinoma treated between 1995 and 2014 were analysed retrospectively. Treatment, complications and prognosis were compared with a historical group of patients ≥ 85 years treated previously between 1978 and 1994 (n = 57) and with a less old group of patients 75 - 84 years old treated between 1995 and 2014 (n = 726)., Results: The cohort consisted of 64 men and 77 women. 88 patients had colon carcinoma, 53 patients rectal carcinoma. 127 patients were treated with tumour resection; 112 were classified as R0. Compared with the historical cohort (1978 - 1994), the number of patients increased, and more patients were given tumour resection (74 vs. 90%, p = 0.003) and fewer patients had synchronous distant metastases (28 vs. 14%, p = 0.015). The 5-year locoregional recurrence rate after curative resection decreased from 11.5 to 1.4% (p = 0.027). Comparison with the younger age group (75 - 84 years) revealed more women (55 vs. 42.3%, p = 0.007), more emergencies (22 vs. 9.8%, p < 0.001) and less frequent neoadjuvant treatment (11 vs. 3%, p = 0.003). Morbidity (41 vs. 31.2%, p = 0.032) and mortality (16 vs. 5%, p < 0.001) were higher in the oldest old. After curative resection and exclusion of postoperative deaths, overall survival (2-year rate 66.4%, 5-year rate 32.9%) was found to be worse than for the less old group, whereas cancer-related survival (2-year rate 93.1%, 5-year rate 86.7%) was similar., Conclusion: The number of oldest old patients ≥ 85 years with colorectal carcinoma will further increase. These patients have a higher risk of postoperative complications. After recovering from the surgery cancer-related survival is not worse than for less old patients., Competing Interests: Die Autoren geben an, dass kein Interessenkonflikt besteht., (Georg Thieme Verlag KG Stuttgart · New York.)
