Background and aims: The aim of this study was to analyze the ability of a training module on a virtual laparoscopic simulator to assess surgical experience in laparoscopy. Methods: One hundred and fifteen participants at the 120th annual convent of the German surgical society took part in this study. All participants were stratified into two groups, one with laparoscopic experience of less than 50 operations (group 1, n=61) and one with laparoscopic experience of more than 50 laparoscopic operations (group 2, n=54). All subjects completed a laparoscopic training module consisting of five different exercises for navigation, coordination, grasping, cutting and clipping. The time to perform each task was measured, as were the path lengths of the instruments and their respective angles representing the economy of the movements. Results between groups were compared using χ2 or Mann-Whitney U-test. Results: Group 1 needed more time for completion of the exercises (median 424 s, range 99-1,376 s) than group 2 (median 315 s, range 168-625 s) (P<0.01). Instrument movements were less economic in group 1 with larger angular pathways, e.g. in the cutting exercise (median 352°, range 104-1,628° vs median 204°, range 107-444°, P<0.01), and longer path lengths (each instrument P<0.05). Conclusion: As time for completion of exercises, instrument path lengths and angular paths are indicators of clinical experience, it can be concluded that laparoscopic skills acquired in the operating room transfer into virtual reality. A laparoscopic simulator can serve as an instrument for the assessment of experience in laparoscopic surgery. [ABSTRACT FROM AUTHOR]

The literature suggests that the main barriers to justice range from a general lack of knowledge about legal rights, and the related prevalent use of technical language within justice systems (which has led to commentators describing law as a ‘leviathan’), to a vague ‘fear of the unknown’. In Germany the principal barrier is thought to be the problem of funding legal services. Empirical research indicates that the question of whether or not to consult a lawyer is primarily one of cost, although over one–third of potential clients have little idea about lawyers’ fees. To find ways to surmount this barrier is therefore of paramount importance for a modern society. In broad terms, there are three potential attitudes to legal costs: reliance on one’s own resources; hope for third party assistance (such as legal aid or pro bono); and insurance. This article concentrates on the last of these three options, comparing, in particular, the systems in Germany and England and Wales. [ABSTRACT FROM AUTHOR]

Background: Within the last years, single-incision laparoscopic cholecystectomy (SLC) emerged as an alternative to multiport laparoscopic cholecystectomy (MLC). SLC has advantages in cosmetic results, and postoperative pain seems lower. Overall complications are comparable between SLC and MLC. However, long-term results of randomized trials are lacking, notably to answer questions about incisional hernia rates, long-term cosmetic impact and chronic pain., Methods: A randomized trial of SLC versus MLC with a total of 193 patients between December 2009 and June 2011 was performed. The primary endpoint was postoperative pain on the first day after surgery. Secondary endpoints were conversion rate, operative time, intraoperative and postoperative morbidity, technical feasibility and hospital stay. A long-term follow-up after surgery was added., Results: Ninety-eight patients (50.8%) underwent SLC, and 95 patients (49.2%) had MLC. Pain on the first postoperative day showed no difference between the operative procedures (SLC vs. MLC, 3.4 ± 1.8 vs. 3.7 ± 1.9, respectively; p = 0.317). No significant differences were observed in operating time or the overall rate of postoperative complications (4.1% vs. 3.2%; p = 0.731). SLC exhibited better cosmetic results in the short term. In the long term, after a mean of 70.4 months, there were no differences in incisional hernia rate, cosmetic results or pain at the incision between the two groups., Conclusions: Taking into account a follow-up rate of 68%, the early postoperative advantages of SLC in relation to cosmetic appearance and pain did not persist in the long term. In the present trial, there was no difference in incisional hernia rates between SLC and MLC, but the sample size is too small for a final conclusion regarding hernia rates., Trial Registration: German Registry of Clinical Trials DRKS00012447.

Background: Single-incision laparoscopic surgery (SILS) is growing in popularity. The increased diameter of the umbilical incision might raise questions about the possibility of a greater risk of postoperative incisional hernia in comparison to conventional laparoscopy. This study aims to disclose the frequency of incisional hernia after SILS in long-term follow-up as well as to reveal the factors predisposing patients to this feared complication., Methods: The patient collective consists of cholecystectomy and appendectomy patients, who were operated on using SILS technique. Follow-up was achieved through letter correspondence, telephone interview, and clinical examination. Effects of demographic variables and operative parameters including age, sex, BMI, ASA score, duration of surgery, pre-existing hernia as well as postoperative incidence of incisional hernia were investigated using univariate and multivariate analyses., Results: A total of 286 cases with complete follow-up were included in the analyses. Mean follow-up duration was 58.4 months. 192 patients (67.1%) underwent cholecystectomy; 94 (32.9%) had an appendectomy. The study collective consisted of 218 women (76.2%) and 68 men (23.8%). Mean age at the date of the operation was 38.5 (median 36, range 13-74). In 5 cases (1.7%), the surgical approach was converted into conventional laparoscopy. Intraoperative complication rate was 0.3% and postoperative complication rate was 5.9%. 7 patients (2.4%) developed an incisional hernia. Obese patients had an incisional hernia incidence of 10.9%. 3 out of 19 patients (15.8%) with a pre-existing umbilical hernia developed an incisional hernia during follow-up. Obesity and pre-existing umbilical hernia proved to have a significant association with incisional hernia incidence in univariate and multivariate analyses. Sex, age, procedure (appendectomy vs cholecystectomy), presence of acute inflammation, and duration of surgery did not show a statistically significant association with incisional hernia., Conclusion: Detection of incisional hernia necessitates a long follow-up duration. Obesity and pre-existing umbilical hernia are associated with a higher incidence of this complication. Following a careful patient selection, SILS offers a safe approach for cholecystectomy and appendectomy procedures.

Background: Incidence rates for urothelial carcinoma (UC) have been reported to differ between countries within the European Union (EU). Besides occupational exposure to chemicals, other substances such as tobacco and nitrite in groundwater have been identified as risk factors for UC. We investigated if regional differences in UC incidence rates are associated with agricultural, industrial and residential land use., Methods: Newly diagnosed cases of UC between 2003 and 2010 were included. Information within 364 administrative districts of Germany from 2004 for land use factors were obtained and calculated as a proportion of the total area of the respective administrative district and as a smoothed proportion. Furthermore, information on smoking habits was included in our analysis. Kulldorff spatial clustering was used to detect different clusters. A negative binomial model was used to test the spatial association between UC incidence as a ratio of observed versus expected incidence rates, land use and smoking habits., Results: We identified 437,847,834 person years with 171,086 cases of UC. Cluster analysis revealed areas with higher incidence of UC than others (p=0.0002). Multivariate analysis including significant pairwise interactions showed that the environmental factors were independently associated with UC (p<0.001). The RR was 1.066 (95% CI 1.052-1.080), 1.066 (95% CI 1.042-1.089) and 1.067 (95% CI 1.045-1.093) for agricultural, industrial and residential areas, respectively, and 0.996 (95% CI 0.869-0.999) for the proportion of never smokers., Conclusion: This study displays regional differences in incidence of UC in Germany. Additionally, results suggest that socioeconomic factors based on agricultural, industrial and residential land use may be associated with UC incidence rates., (Copyright © 2017 Elsevier Ltd.

Background: The demographic change in Germany with an aging population and the resulting necessity of adequate surgical care for older patients was lately discussed with concern. One major aspect is the estimated higher treatment costs in the care of the elderly., Materials and Methods: InEK data from all cases of patients over the age of 80, who were treated and discharged from 2008 to 2012 as inpatients at the Department of General, Visceral, Vascular and Thoracic Surgery at the Charité - Universitätsmedizin Berlin, Campus Mitte, were analysed. Of a total of 13,612 patients 626 patients were over the age of 80. Their lengths of stay, mode of discharge and discharge management as well as costs and reimbursements according to the relevant diagnosis-related groups were analysed., Results: Cases of elderly patients amounted to a stable 5 % of all cases from 2008 until 2012. Their mean length of stay was 14 (median, 9), range, 1-129 days. 80 % of patients could be regularly discharged, 9 % died, 8 % were transferred to another hospital, 2 % discharged into a nursing home and 1 % into a rehabilitation centre. The elderly patients had a patient clinical complexity level of mean 2.84. Costs per day amounted to a mean 778 (median: 627) €, range: 306-7740 €, total costs to 10,686 (median: 5140) €, range: 368-186,059 €. The mean deficit was 491 (median: 176) € per patient, range: - 30,470-75,144 €. The discharge management was significantly different in comparison to patients under the age of 80 with respect to avoidance of discharge at the weekend., Conclusion: Patients over the age of 80 are a relevant group in surgery. They have an increased perioperative risk, but patients should not be denied surgery solely because of their age. The perioperative management of the elderly has to be of maximum standardised quality. From an economic perspective it can be stated that elderly patients currently pose no exceptional financial risk to a surgical department, but contribute relevantly to the turnover, whereby special attention has to be paid to an early structured discharge management., (Georg Thieme Verlag KG Stuttgart · New York.)

Background: Cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (HIPEC) offers patients with peritoneal cancer of various origins the chance of a relevant increase in life expectancy. These cases are very complex from a medical viewpoint and very expensive from an economical aspect. An analysis of case cost calculations was performed to find out whether this procedure can on average be carried out cost-effectively by a maximum care university., Materials and Methods: All cases from 2008 in which HIPEC was carried out were analyzed. The types of main diagnosis, secondary diagnoses, procedures, times from incision to suture and hospital stay were analyzed. On the basis of the case costs the proceeds and marginal returns were calculated from the diagnosis-related groups (DRGs) and additional remuneration when applicable. The causes of positive and negative marginal returns were explained using the InEK cost matrix., Results: In 18 patients there were 9 different main diagnoses and 7 different "main procedures" (from a surgical perspective the most resource intensive procedures) and a total of 10 different DRGs were identified in the grouping algorithm. With an average of 2 operations (range 1-7) per patient the summed incision-to-suture time was 423 min (170-962 min). The patients stayed on average 6.4 days (1.3-17.6 days) in intensive care. The average case cost was 21,072€ (range 8,657-55,904€) and the proceeds 20,474€ (6,333-37,497€). Each case had on average a debit balance of 598€ (range from 11,843€ profit balance to 18,407€ debit balance) with an assumed base rate of 2,786€. The causes for positive or negative marginal profits were mostly operating times, incision-to-suture times and duration of intensive care., Conclusions: The proceeds showed on average a deficit of only 3% compared to the costs. The operating times must be decreased by optimization particularly of the preoperative approach. Interventions should be carried out in one stage only and the intraoperative connecting and waiting times should be reduced in order to reduce the incision-to-suture times.

Objectives: "Fast-track" rehabilitation is a multimodal perioperative treatment concept for accelerating postoperative recovery which has been already used successfully in visceral surgery. Of its use in thoracic surgery however, almost no data exist and the relevance of this concept for pulmonary operations is unknown., Patients and Methods: In this prospective study we examined a new perioperative fast-track treatment concept for thoracic surgery and evaluated the results. This program employs detailed information of patients, intensive perioperative respiratory therapy, thoracic peridural analgesia, forced mobilization, and an early start of postoperative normal food intake., Results: Fifty consecutive patients with benign or malignant diseases of the lung aged an average of 64 years (range 22-78) were operated on thoracoscopically (n=15) or with thoracotomy (n=35) and treated perioperatively using the fast-track program. All patients were mobilized beginning 4 h postoperatively and had normal food. The incidence of general postoperative complications was 0% in this study. Postoperative stay lasted 4.5 days (range 1.5-28.5). There was no increase in surgical complications, and 6% of the patients were readmitted. The patients' acceptance of this concept was high., Conclusion: Fast-track rehabilitation resulted in a decreased rate of general complications and accelerated rehabilitation in thoracic surgery.

Background: New demands and possibilities of collaboration between hospitals and private practices in Germany have appeared, now that the way has been opened legally. A poll was conducted to analyse the current status of collaboration between outpatient gastroenterologists and hospital surgical departments and to identify possible future collaborations., Materials and Methods: One thousand twenty-six private practices specialising in endoscopy were found by contacting the Association of Statutory Health Insurance Physicians and additional internet research. Of these, 50% were randomly selected (513 private practices) and contacted by mail with anonymous questionnaires about cooperation with their clinical partners. Two hundred three (39.6%) practices responded, of which 200 could be analysed., Results: Of all practices reached, 75% considered the cooperation with clinics very valuable or even exceptional. Still, almost half (46%) suggested necessary improvements in these collaborations. Around a third of all contacted colleagues were already involved in projects following integrated care models. In about 80% of all participants, the main interest in integrated models was specified to be common therapy planning., Conclusion: The data analysis of this study shows a substantial interest of private-practice gastroenterologists in close collaboration with hospitals. It is now up to the hospitals to open contracts with their medical outpatient partners.
