Background and Aims: Despite recent advancements in medical and surgical techniques in patients suffering from Crohn`s disease [CD], postoperative morbidity remains relevant due to a long-standing, non-curable disease burden. As demonstrated for oncological patients, perioperative enhanced recovery concepts provide great potential to improve postoperative outcome. However, robust evidence about the effect of perioperative enhanced recovery concepts in the specific cohort of CD patients is lacking., Methods: In a prospective, single-centre study, all patients receiving ileocaecal resection due to CD between 2020 and 2023 were included. A specific, perioperative, enhanced recovery concept [ERC] was implemented and patients were divided into two groups [before and after implementation]. The primary outcome focused on postoperative complications as measured by the Comprehensive Complication Index [CCI], secondary endpoints were severe complications, length of hospital stay, and rates of re-admission., Results: Of 83 patients analysed, 33 patients participated in the enhanced recovery programme [post-ERC]. Whereas patient characteristics were comparable between both groups, ERC resulted in significantly decreased rates of overall and severe postoperative complications [CCI: 21.4 versus 8.4, p = 0.0036; Clavien Dindo > 2: 38% versus 3.1%, p = 0.0002]. Additionally, post-ERC-patients were ready earlier for discharge [5 days versus 6.5 days, p = 0.001] and rates of re-admission were significantly lower [3.1% versus 20%, p = 0.03]. In a multivariate analysis, the recovery concept was identified as independent factor to reduce severe postoperative complications [p = 0.019]., Conclusion: A specific, perioperative, enhanced recovery concept significantly improves the postoperative outcome of patients suffering from Crohn`s disease., (© The Author(s) 2024.

Background: Multimodal optimized perioperative management (mPOM, fast-track, enhanced recovery after surgery, ERAS) leads to a significantly accelerated recovery of patients with elective colorectal resections. Nevertheless, fast-track surgery has not yet become established in everyday clinical practice in Germany. We present the results of a structured fast-track implementation in five German hospitals., Methods: Prospective data collection in the context of a 13-month structured fast-track implementation. All patients ≥ 18 years undergoing elective colorectal resection and who gave informed consent were included. After 3 months of preparation (pre-FAST), fast-track treatment was initiated and continued for 10 months (FAST). Outcome criteria were adherence to internationally recommended fast-track elements, postoperative complications, functional recovery, and postoperative hospital stay., Results: Data from 192 pre-FAST and 529 FAST patients were analyzed. Age, sex, patient risk, location, and type of disease were not different between both groups. The FAST patients were more likely to have undergone minimally invasive surgery (82% vs. 69%). Fast-track adherence increased from 52% (35-65%) under traditional treatment to 83% (65-96%) under fast-track treatment (p < 0.01). The duration until the end of infusion treatment, removal of the bladder catheter, first bowel movement, oral solid food, regaining autonomy, suitability for discharge and postoperative length of stay were significantly lower in the FAST group. Complications, reoperations, and readmission rates did not differ., Conclusion: Fast-track adherence rates > 75% can also be achieved in German hospitals through structured fast-track implementation and the recovery of patients can be significantly accelerated., (© 2023.

Aim: This manuscript provides information on the history, principles, and clinical results of Fast-track or ERAS concepts to optimize perioperative management (OPM)., Methods: With the focus on elective colorectal surgery description of the OPM concept and its elements for with special attention to the prevention of infectious complications and clinical results compared to traditional care will be given using recent systematic literature reviews. Additionally, clinical results for other major abdominal procedures are given., Results: An optimized perioperative management protocol for elective colorectal resections will currently consist of 25 perioperative elements. These elements include the time from before hospital admission (patient education, screening, and treatment of possible risk factors like anemia, malnutrition, cessation of nicotine or alcohol abuse, optimization of concurrent systemic disease, physical prehabilitation, carbohydrate loading, adequate bowel preparation) to the preoperative period (shortened fasting, non-sedative premedication, prophylaxis of PONV and thromboembolic complications), intraoperative measures (systemic antibiotic prophylaxis, standardized anesthesia, normothermia and normovolemia, minimally invasive surgery, avoidance of drains and tubes) as well as postoperative actions (early oral feeding, enforced mobilization, early removal of a urinary catheter, stimulation of intestinal propulsion, control of hyperglycemia). Most of these elements are based on high-level evidence and will also have effects on the incidence of postoperative infectious complications., Conclusion: Optimized perioperative management should be mandatory for elective surgery today as it enhances postoperative patient recovery, reduces morbidity and infectious complications., Competing Interests: The author declares that he has no competing interests., (Copyright © 2022 Schwenk.)

Fast-track treatment pathways reduce the frequency of postoperative complications in elective colorectal resections by approximately 40% and due to the rapid recovery reduce the postoperative duration of hospitalization by approximately 50%. Specialized nursing personnel (enhanced recovery after surgery, ERAS, nurses) have already been appointed internationally to accompany and monitor the execution of multimodal perioperative treatment. In November 2018 a fast-track assistant was appointed in the Clinic for General and Visceral Surgery of the Municipal Clinic in Solingen for coordination of the fast-track treatment pathway. The results confirmed that a high adherence to perioperative fast-track treatment concepts can also be achieved in the German healthcare system by the assignment of specialized nursing personnel, with the known advantages for patients, nursing personnel, physicians and hospital sponsors., (© 2021.

Malignancies are among the most common diseases, especially in old age, and are responsible for 25% of all deaths in Germany. Especially carcinomas of the gastrointestinal tract can be cured in most cases only through extensive surgery with significant morbidity. About 25 years ago, the multimodal, perioperative Fast Track (FT) concept for reducing postoperative complications was introduced and additional elements were added in the following years. Meanwhile, there is growing evidence that adherence to the key elements of more than 70% leads to reduction in postoperative adverse events as well as a shorter hospital stay and could be associated with an improved oncological outcome. Despite the high level of awareness and the proven advantages of the FT concept, the implementation and maintenance of the measures is difficult and results in an adherence of only 20 - 40%. There are many reasons for this: In addition to a lack of interdisciplinary and interprofessional cooperation and the time consuming and extended logistical efforts, limited human resources are often listed as one of the main causes. We took these aspects as an opportunity and started to develop a S3 guideline for perioperative treatment to accelerate the recovery of patients with gastrointestinal malignancies. By creating a consensus- and evidence-based, multidisciplinary guideline, many of the problems listed above could probably be solved by optimising and standardising interdisciplinary care, which is particularly important in a setting with many different disciplines and their competing interests. Furthermore, the standardisation of the perioperative procedures will reduce the time and logistical effort. The presentation of the evidence allows increased transparency and justifies the additional personnel expenditure on hospital medicine and health insurance companies. In addition, the evidence-based quality indicators generated during the development of the guideline make it possible to include perioperative standards in certification systems and thus to measure and check the quality of perioperative care., Competing Interests: Wolfgang Schwenk: Geschäftsführer GOPOM GmbH (Gesellschaft für Optimiertes PeriOperatives Management) in Düsseldorf seit 01.03.2021.

Fast-track or ERAS programs can give clinically relevant benefits for patients undergoing surgery. They also have financial advantages for the hospital. Despite these facts, fast-track has been implemented in only very few hospitals in Germany. Neither scientific evidence nor reimbursement regulations explain this lack of fast-track acceptance. It seems however that a structured process of change from traditional perioperative medicine to evidence based fast-track therapy is missing in Germany. In other countries, structured programs for fast-track or ERAS implementation have been successful in many hospitals. This article describes structured fast-track implementation divided into three consecutive steps: organisational preparation, clinical implementation and continuous examination of fast-track adherence, functional recovery, morbidity and postoperative length of hospital stay. Due to its complex nature, fast-track implementation should be guided by external fast-track experts., Competing Interests: W. S. hat in den letzten 5 Jahren von den Firmen B.

Introduction: Perioperative enhanced recovery after surgery (ERAS) concepts or fast-track are supposed to accelerate recovery after surgery, reduce postoperative complications and shorten the hospital stay when compared to traditional perioperative treatment., Methods: Electronic search of the PubMed database to identify systematic reviews with meta-analysis (SR) comparing ERAS and traditional treatment., Results: The presented SR investigated 70 randomized controlled studies (RCT) with 12,986 patients and 93 non-RCT (24,335 patients) concerning abdominal, thoracic and vascular as well as orthopedic surgery. The complication rates were decreased under ERAS following colorectal esophageal, liver and pulmonary resections as well as after implantation of hip endoprostheses. Pulmonary complications were reduced after ERAS esophageal, gastric and pulmonary resections. The first bowel movements occurred earlier after ERAS colorectal resections and delayed gastric emptying was less often observed after ERAS pancreatic resection. Following ERAS fast-track esophageal resection, anastomotic leakage was diagnosed less often as well as surgical complications after ERAS pulmonary resection. The ERAS in all studies concerning orthopedic surgery and trials investigating implantation of a hip endoprosthesis or knee endoprosthesis reduced the risk for postoperative blood transfusions. Regardless of the type of surgery, ERAS shortened hospital stay without increasing readmissions., Conclusion: Numerous clinical trials have confirmed that ERAS reduces postoperative morbidity, shortens hospital stay and accelerates recovery without increasing readmission rates following most surgical operations.

The paradigm shift in the treatment concept for acute appendicitis is currently the subject of intensive discussions. The diagnosis and differentiation of an uncomplicated from a complicated appendicitis as well as the selection of an adequate treatment is very challenging, especially since nonoperative treatment models have been published. The laparoscopic appendectomy is still the standard for most cases. Guidelines for the treatment of acute appendicitis do not exist in Germany. Therefore, a group of experts elaborated 21 recommendations on the treatment of acute appendicitis after 3 meetings. After initial definition of population, intervention, comparison and outcome (PICO) questions, recommendations have been finalized through the Delphi voting system. The results were evaluated according to the current literature. The aim of this initiative was to define a basic support for decision making in the clinical routine for treatment of acute appendicitis.

Background: For more than a decade the evolving concept of fast track surgery has been implemented, predominantly in colorectal surgery. The practice of fast track surgery has yielded excellent results concerning reduction of postoperative complications and hospital stay and has been shown to increase patient satisfaction; however, several studies have shown a sometimes alarmingly low rate of implementation of the individual fast track measures and the rate is a maximum of 44%., Objective: In this review, obstacles for implementation of fast track surgery are investigated. Advice is given on possible solutions to circumvent obstacles and facilitate successful establishment of multimodal recovery protocols in individual institutions., Material and Methods: The current international literature is critically evaluated and discussed with a particular focus on prospective clinical trials and expert recommendations., Results: The reasons for a lack of adherence to fast track surgery principles have been shown to be multifactorial. Time-consuming expenditure, logistic difficulties, lack of support by colleagues as well as limitations in the healthcare system and patient-dependent factors appear to complicate implementation of fast track programs., Conclusion: Successful implementation and long-term perpetuation can be achieved only by an interdisciplinary team with a low level hierarchy, continuous training and a positive feedback culture. An early inclusion and clarification of personnel and patients should be firmly integrated into the fast track concept. This results in a higher satisfaction of patients and personnel and subsequently stronger adherence to the fast track concept.

The treatment of any causal, procedure-specific and/or concomitant acute pain is an essential quality feature in any surgical subspecialty. An interdisciplinary and interprofessional pain therapy aims for an immediate improvement of the patients' quality of life, a reduction of the risk of postoperative morbidity and mortality in the medium term, prevention of any pain chronification in the long run as well as a reduction of hospitalization and sick leave. The "Agreement of the Professional Association of German Anesthesiologists and the Professional Association of German Surgeons for the Organization of Postoperative Pain Therapy" exists since 1992. In view of the continuously developing scientific evidence, updated guideline recommendations and interprofessionally designed treatment pathways, these agreements have been adapted to the current requirements and structural conditions of the German healthcare system. Thus, both aforementioned professional associations promote an up to date version of an "Agreement for the Organization of Pain Therapy for Surgical Patients", a precise recommendation and a manual for the acting partners in order to realize the abovementioned goals.

Diverticular bleeding is a complication of diverticular disease but in contrast to diverticulitis, publications concerning diverticular bleeding are less common. Diverticular bleeding is the cause of approximately 20-50% of cases of lower gastrointestinal bleeding and in rare cases can be life-threatening. The main symptom of diverticular hemorrhage is painless hematochezia and the German guidelines recommend that further diagnostics of suspected diverticular bleeding should be performed in hospital. Interdisciplinary diagnostic and therapeutic algorithms recommend primary endoscopy in acute as well as chronic recurrent diverticular bleeding. If endoscopy fails to provide an exact localization of the origin of bleeding, angiography or computed tomography (CT) angiography can be performed. The 99m Tc erythrocyte scintigraphy should only be performed if endoscopy and angiography are unable to identify the localization of the bleeding source. More than 90% of diverticular hemorrhages stop spontaneously; however, it is general agreed that an active diverticular bleeding detected during colonoscopy should be immediately treated endoscopically. Alternative radiological techniques for hemostasis are rarely needed and attention must be paid to the complications. In the rare case of severe bleeding that cannot otherwise be stopped or if the bleeding vessel cannot be located, laparotomy and total colectomy can be recommended. If the diverticular bleeding has definitely been identified or recurrent bleeding causes chronic anemia, segmental or total colectomy may be undertaken; however, the advantages and disadvantages of both types of surgery have to be thoroughly explained to the patient.

Background: Complications are common after ostomy surgery. Data from the Berlin OStomy Study were evaluated to determine risk factors for complications., Patients and Methods: Patients with a bowel ostomy were questioned using a questionnaire concerning patients' characteristics and history as well as the ostomy and its complications. The questionnaire also contained a nine-fielded abdominal sketch to determine the exact ostomy location., Results: Over 42 months, 2647 patients completed the questionnaire. Obese patients and patients after emergency surgery were more prone to ostomy-related complications. This result was independent of the kind of ostomy (small bowel ostomy or colostomy) and of the abdominal location. The overall ostomy complication rate was 55.6%., Conclusion: Significantly more complications were recorded after emergency surgery and in obese patients than after elective surgery and in non-obese patients, respectively. There was no preferential abdominal location for avoiding general ostomy complications. The results emphasized the importance of preoperative ostomy site marking by qualified personnel such as ostomy nurses or surgeons to reduce complication rates by respecting individual abdominal configurations. With an increasing prevalence of obesity, ostomy surgery will become even more challenging in the future. A division of the abdominal wall into nine regions might be helpful and more precise for describing and examining ostomy-related complications in the future.

Background: Elderly patients are a growing and vulnerable group with an elevated perioperative risk. Perioperative treatment pathways that take these patients' special risks and requirements into account are often not implemented in routine clinical practice., Methods: This review is based on pertinent publications retrieved by a selective search in PubMed, the AWMF guideline database, and the Cochrane database for guidelines from Germany and abroad, meta-analyses, and Cochrane reviews., Results: The care of elderly patients who need surgery calls for an interdisciplinary, interprofessional treatment concept. One component of this concept is preoperative preparation of the patient ("prehabilitation"), which is best initiated before hospital admission, e.g., correction of deficiency states, optimization of chronic drug treatment, and respiratory training. Another important component consists of pre-, intra-, and postoperative measures to prevent delirium, which can lower the frequency of this complication by 30-50%: these include orientation aids, avoidance of inappropriate drugs for elderly patients, adequate analgesia, early mobilization, short fasting times, and a perioperative nutrition plan. Preexisting cognitive impairment predisposes to postoperative delirium (odds ratios [OR] ranging from 2.5 to 4.5). Frailty is the most important predictor of the postoperative course (OR: 2.6-11). It follows that preoperative assessment of the patient's functional and cognitive status is essential., Concluzion: The evidence-based and guideline-consistent care of elderly patients requires not only close interdisciplinary, interprofessional, and cross-sectoral collaboration, but also the restructuring and optimization of habitual procedural pathways in the hospital. Elderly patients' special needs can only be met by a treatment concept in which the entire perioperative phase is considered as a single, coherent process.

Background: Morbidity and mortality (M&M) conferences are essential instruments for quality improvement in surgical departments; however, publications concerning the detailed contents of M&M conferences are rare and have not been published in the German language., Objective: Detailed analysis of the content of a weekly M&M conference in a department of general and visceral surgery., Material and Methods: Data from a weekly M&M conference were prospectively collected. Epidemiological data, diagnosis, type of surgery, morbidity, postoperative course and mortality were documented for each patient. Type (surgical vs. medicinal) and severity (I-V according to Clavien-Dindo classification) of complications were analyzed., Results: From 1 January 2010 to 31 December 2014 a total of 761 out of 11,470 patients with a mean age of 62.2 (15.9) years were discussed in the M&M conferences. Of the M&M patients 39.4% were female, 88.9% showed surgical complications while 28.9% were diagnosed with a medical complication and 91 patients (12.0%) died. Complications were classified as Clavien-Dindo I: 27.9%, II: 10.5%, III: 37.7%, IV: 12% and V: 12.0%. Most surgical complications were classified as Clavien-Dindo I (30.0%) and Clavien-Dindo III (40.9%), medical complications were most often classified as Clavien-Dindo IV (29.6%) and V (34.6%). Wound healing impairment (41%), pulmonary complications (16.6%), anastomotic leakage (15.6%), septic (8.9%) and cardiac (8.0%) complications were discussed most often. Cardiac, pulmonary and septic complications were the main cause of morbidity in deceased patients., Conclusion: The M&M conferences display a morbidity profile of each surgical department. Depending on the speciality and focus of a surgical department, the content of the M&M conferences will vary. Detailed knowledge about the content of M&M conferences enable specific measures to be taken to improve quality and patient safety.

Background: Unplanned admissions or readmissions to the intensive care unit lead to a poorer outcome and present medical, logistic and economic challenges for a clinic. How often and what are the reasons for readmission to the intensive care unit? Which strategies and guidelines to avoid readmission are recommended., Material and Methods: Analysis and discussion of available studies and recommendations of national and international societies., Results: Many studies show that unplanned admissions and readmissions to the intensive care unit represent an independent risk factor for a poor outcome for patients. Different factors that increase the probability of readmission can be identified. Structural changes concerning the normal wards, intensive care unit or the clinic internal emergency service could positively effect readmission rates and/or patient outcome while other studies failed to show any effect of these arrangements., Conclusion: Patient transition from the intensive care unit to a lower level of care is a critical point of time and has to be accompanied by a high quality handover. Unstable patients on normal wards have to be identified and treated as soon as possible but effects of standardized medical emergency teams are controversial.

Klinefelter syndrome is the most frequent chromosomal aneuploidy in males occurring in about 1 in 660 males. Epidemiological studies have demonstrated increased risk of type 1 diabetes and type 2 diabetes in adults with Klinefelter syndrome. There is only one previous report of neonatal diabetes in a patient with Klinefelter syndrome. We report transient neonatal diabetes due to a pathogenic heterozygous variant in KCNJ11 in a male infant with Klinefelter syndrome. A 78-day old male infant was noted to have sustained hyperglycemia with serum glucose ranging between 148 mg/dL (8.2 mmol/L) and 381 mg/dL (21.2 mmol/L) three days after undergoing a complete repair of an atrioventricular defect. Hemoglobin A1c was 6.6%. The patient was born at term with a birth weight of 2.16 kg following a pregnancy complicated by gestational diabetes that was controlled with diet. The patient was initially started on a continuous intravenous insulin drip and subsequently placed on subcutaneous insulin (glargine, human isophane and regular insulin). Insulin was gradually decreased and eventually discontinued at seven months of age. Chromosomal microarray at 11 weeks of age showed XXY and a panel-based, molecular test for neonatal diabetes revealed a pathogenic heterozygous variant c.685G>A (p.Glu229Lys) in KCNJ11. The patient is now 34 months old and continues to have normal fasting and post-prandial glucose and HbA1C levels. The patient will need prospective follow up for assessment of his glycemic status. To our knowledge this is the second reported case of neonatal diabetes in an infant with Klinefelter syndrome and the first due to a mutation in the KCNJ11 in a patient with Klinefelter syndrome.

Background: Immature ovarian teratoma is very rare in childhood. We report on a 12-year-old girl with immature ovarian teratoma who presented initially with syndrome of inappropriate antidiuretic hormone., Case: A 12-year-old girl presented with acute abdomen and distention. Initial laboratory tests showed hyponatremia (sodium, 123 mmol/L), that did not respond to fluid management. Computed tomography imaging showed a 15 cm × 9 cm × 20 cm mass in the right ovary with multifocal internal fat, and dystrophic calcifications. She underwent exploratory laparotomy with a right salpingo-oophorectomy, omentectomy, and peritoneal stripping. The pathology revealed metastatic immature teratoma. Hyponatremia resolved soon after the surgery., Summary and Conclusion: Although a rare diagnosis, immature ovarian teratoma must be considered in a girl who presents with abdominal mass and hyponatremia., (Copyright © 2017 North American Society for Pediatric and Adolescent Gynecology.

Pediatricians have relied on methods for determining skeletal maturation for >75 years. Bone age continues to be a valuable tool in assessing children's health. New technology for bone age determination includes computer-automated readings and assessments obtained from alternative imaging modalities. In addition, new nonclinical bone age applications are evolving, particularly pertaining to immigration and children's rights to asylum. Given the significant implications when bone ages are used in high-stake decisions, it is necessary to recognize recently described limitations in predicting accurate age in various ethnicities and diseases. Current methods of assessing skeletal maturation are derived from primarily white populations. In modern studies, researchers have explored the accuracy of bone age across various ethnicities in the United States. Researchers suggest there is evidence that indicates the bone ages obtained from current methods are less generalizable to children of other ethnicities, particularly children with African and certain Asian backgrounds. Many of the contemporary methods of bone age determination may be calibrated to individual populations and hold promise to perform better in a wider range of ethnicities, but more data are needed., Competing Interests: POTENTIAL CONFLICT OF INTEREST: The authors have indicated they have no potential conflicts of interest to disclose., (Copyright © 2017 by the American Academy of Pediatrics.)

Background: Preoperative evaluation of patient risk is an essential component of patient preparation before surgery. Guidelines provide evidence-based algorithms for preoperative assessment of cardiac risk; however, even experienced physicians correctly apply evidence-based algorithms in only 50% of all cases or less., Objective: A checklist system for guideline-based cardiopulmonary risk evaluation in adult patients undergoing abdominal or visceral surgery (CAVE checklists) was created to assist in preoperative cardiopulmonary risk assessment and increase correct application of evidence-based algorithms before elective visceral surgery., Material Und Methods: International guidelines were transformed into a checklist system. These checklists were than evaluated in a department of general and visceral surgery. The main goal was to determine whether preoperative examinations, such as electrocardiograph (ECG), chest-x-ray, spirometry and advanced assessment by a cardiologist, are performed according to evidence-based guidelines. The frequency of recommended as well as unnecessary and missed examinations was assessed., Results: In this study 541 patients with a median age of 64.5 years (interquartile range: 52-73 years) were examined using the checklist system. Of the patients 90.4% underwent ECG and 98.5% chest-X-ray as recommended in the guidelines. Spirometry was not recommended in any patient and not performed in any case. Advanced assessment by a cardiologist was performed in 45.5% of cases as recommended in the guidelines. When guidelines did not recommend ECG, x‑ray, spirometry or advanced cardiac assessment, 69.4%, 99.6%, 99.3% and 99.8% of patients, respectively, actually did not receive these examinations. Only 2.8% of all patients did not receive an examination that was recommended by the guidelines: 1.5% ECG, 0.2% x‑ray and 1.1% advanced cardiological assessment. None of these patients suffered from postoperative cardiopulmonary complications., Conclusion: These simple checklists are easy to use and provide a higher degree of evidence-based preoperative cardiopulmonary risk evaluation than previously reported in the literature. Adaptation of the checklists to changing guidelines is easy to perform. Whether the application of these checklists will result in a reduction of morbidity and costs have to be determined in further clinical trials.

Patient blood management is a multimodal concept that aims to detect, prevent and treat anemia, optimize hemostasis, minimize iatrogenic blood loss, and support a patient-centered decision to provide optimal use of allogeneic blood products. Although the World Health Organization (WHO) has already recommended patient blood management as a new standard in 2010, many hospitals have not implemented it at all or only in part in clinical practice. The German Society of Anaesthesiology and Intensive Care Medicine and the German Society of Surgery therefore demand that i) all professionals involved in the treatment should implement important aspects of patient blood management considering local conditions, and ii) the structural, administrative and budgetary conditions should be created in the health care system to implement more intensively many of the measures in Germany.

Background: Although ostomies are sometimes necessary, it is unclear which type of ostomy is advantageous for quality of life (QoL). In an observational study of 2647 patients, QoL after colostomy (CS) and small bowel stoma (SBS) formation was evaluated., Methods: The European Organisation for Research and Treatment of Cancer (EORTC)-QLQ-C30 and CR-38 questionnaires were used. Patient characteristics, retrospective information about the ostomy and previous treatments, and current stoma-related complications were recorded. All questionnaires were distributed and collected by stoma therapists at the homecare company PubliCare®., Results: In all, 1790 patients had a CS, and 756 had an SBS. The mean Global Health Score (mGHS-a general QoL indicator) was 52.33 in CS and 49.40 in SBS patients (p = 0.004), but the effect size (Cohen's d) was 0.1. In SBS patients, all functional scores were lower and most of the symptom scores were higher., Conclusions: QoL differed significantly for CS and SBS patients, but the effect size was marginal. The care of certain patient groups, particularly (female) patients who receive emergency surgeries, must be improved. More professional education and guidance are necessary for a larger proportion of patients. This survey provided reference data for quality of life in patients with an ostomy.

Psychological interventions can improve Quality of Life (QoL). Object of interest was if different psychological interventions influence short-term QoL after colonic resection for carcinoma. Furthermore, we wanted to see if there is a correlation between patients` preoperative affect and postoperative QoL. Sixty patients that underwent colorectal surgery were divided into three groups. Group one (n = 20) received Guided Imagery and group 2 (n = 22) Progressive Muscle Relaxation. The third group (Control, n = 18) had no intervention. Quality of Life (QoL) was measured using the EORTC QLQ-C30 and the Gastrointestinal Quality of life Index (GIQLI). Patients' affect was measured by the PANAS questionnaire. The higher the preoperative Negative Affect was, the lower were the scores for QoL on the 30th postoperative day. Patients' QoL was highest preoperatively and lowest on the third postoperative day. On the 30th postoperative day scores for QoL were almost as high as preoperative without difference between the three groups. Neither Guided Imagery nor Progressive Relaxation was influencing short-term QoL measured by the EORTC QLQ-C30 and the GIQLI questionnaire after colorectal surgery for cancer. Screening patients' with the PANAS questionnaire might help to identify individuals that are more likely to have a worse QoL postoperatively., (© 2016 The Authors.

Background: Cardiac complications are an important cause of morbidity and mortality observed after esophageal resections. We examined whether an high intrathoracic vagotomy during abdominothoracic esophagectomy would have an effect on intraoperative and early postoperative cardiac function in the setting of a minimally invasive resection. Two hypotheses were generated for this study: (1) Vagotomy would cause cardiac changes, and (2) vagus-preserving esophagectomy would prevent cardiac problems during resection and in the early postoperative phase., Methods and Results: Thirty male pigs were operated on while cardiac parameters (heart rate [HR], cardiac index [CI], preload recruitable stroke work [PRSW], contractility speed [dp/dtmax], relaxation speed [dp/dtmin], and relaxation time [tau]) were monitored using a conductance catheter and the thermodilution method. Animals were randomized into 4 groups (each n = 7): (1) control, thoracoscopy only, (2) thoracoscopy with vagotomy, (3) esophageal resection with vagotomy, and (4) esophageal resection with vagus nerve preservation. To evaluate the first hypothesis, we compared groups 1 and 2; to evaluate the second hypothesis, we compared groups 3 and 4. HR, CI, PRSW, dp/dtmax, and tau were different in the 2 groups without resection (area under the curve; each P < .05). Vagotomy with esophagectomy resulted in nonsignificant differences between groups 3 and 4. The requirement for metoprolol administration to avoid severe tachycardia was greater in the groups that underwent vagotomy (P < .05; Fisher's exact test)., Conclusion: An high intrathoracic vagotomy results in loss of vagal tone and a greater rate of tachycardia during thoracoscopy and esophagectomy. There were no differences, however, in cardiac dynamics between the esophagectomy groups. Thus, vagal injury is not the sole reason for cardiac dysfunction after esophagectomy., (Copyright © 2014 Mosby, Inc. All rights reserved.)

Background: The development of modern videoendoscopy enables surgeons to perform laparoscopic resection of colonic cancer., Aim: This manuscript evaluated the literature concerning clinically relevant differences in the short and long-term course after laparoscopic or conventional resection of colonic cancer., Methods: An investigation of meta-analyses from randomized controlled clinical trials comparing laparoscopic and conventional surgery for colonic cancer was carried out., Results: The incidence of intraoperative complications was higher during laparoscopic surgery, the duration of surgery was increased and blood loss was less when compared to open surgery. Overall morbidity and the incidence of surgical complications were decreased after laparoscopic surgery. General morbidity and mortality were not different after laparoscopic or open resection of colonic cancer. Duration of hospital stay was shorter but was also associated with the type of perioperative care (i.e. traditional or enhanced recovery). Following minimally invasive or conventional resection, the incidence of tumor recurrence (local and distant) and the duration of survival (overall and disease-free) showed no differences. Wound implantations were rare after both operative techniques but with a tendency to occur more often after laparoscopic than open resection., Conclusion: Laparoscopic resection of colonic cancer has clinically relevant short-term benefits for the patients and long-term results are not different from open colectomy. However, most of the patients included in randomized controlled trials underwent right or left colectomy and sigmoid or rectosigmoid resections. Data with a high level of evidence concerning carcinomas of the flexures or the transverse colon do not exist. Suitable patients with colonic cancer should undergo laparoscopic resection by experienced surgeons.

Background: While enhanced recovery after surgery (ERAS) programs are the standard for perioperative management, special nutritional care has to be administered to malnourished patients and those at metabolic risk with special regard to patients with postoperative complications., Methods: Existing guidelines of the German and European societies of nutritional medicine (DGEM and ESPEN) on enteral and parenteral nutrition in surgery were merged and in accordance with the principles of the Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgesellschaften (AWMF, German Association of the Scientific Medical Societies) and Ärztliches Zentrum für Qualität in der Medizin (AeZQ, German Agency for Quality in Medicine) revised and extended., Results and Discussion: The working group developed 41 consensus-based recommendations for perioperative nutrition. The recommendation strength is: 9x A (recommendation based on significant good quality literature containing at least one randomized controlled trial), 12x B (recommendation based on well-designed trial without randomization), 13x C (recommendation based on expert opinions and/or clinical experience of respected authorities) and 7x CCP (clinical consensus point)., Conclusion: Even in patients without obvious malnutrition perioperative nutritional support is indicated when oral food intake is not feasible or inadequate for a longer period of time.

Background: Insufficient nutrition in surgical patients increases perioperative morbidity, mortality, length of stay and therapy costs. Therefore, guidelines declare the integration of nutrition into the overall management as one of the key aspects of perioperative care. This study was conducted to evaluate the current clinical practice of clinical nutrition in surgical departments in Germany., Methods: In 2009 German Surgical Society (DGCH) members in leading positions were surveyed with a standardised online questionnaire concerning their perioperative nutritional routines in elective surgery., Results: From the addressed physicians n = 156 (6.24 %) answered. Of those, 86.9 % consider the nutritional status of their patients. Only 6 % use standardised nutritional screening tools. Short preoperative fasting for solid and liquid food is practiced by 65 % and 40 %, respectively. After the operation, 65 % allow intake of clear fluids on the day of surgery and 78 % initiate solid food on the day of surgery or the first postoperative day. Oral nutritional supplements are given only "sometimes" or "rarely" by 53.9 % of the respondents., Conclusion: The low response rate may imply the dilemma that the evidence-based benefit of perioperative nutrition does not meet sufficient interest. Even in case of a positive selection of "pro-nutrition respondents", standardised preoperative malnutrition screening is also rare. Aspects such as shorter perioperative fasting are already practiced more progressively. However, still greater efforts are needed to promote guideline-based clinical nutrition in surgical care in Germany., (© Georg Thieme Verlag KG Stuttgart · New York.)

One of the most important aspects of a well-child examination is an assessment of a child's growth. Children who are failing to grow are often labeled "failure to thrive." However, close examination of the pattern of growth on standardized growth charts often allows the caregiver to characterize the growth failure as failure to grow, failure to gain weight, or failure to grow and gain weight. Such refinement of the pattern of growth failure allows for a more specific differential diagnosis and helps to focus laboratory and radiographic evaluation.

Purpose: The aim of this study was to investigate the effects of a restrictive vs. a liberal postoperative fluid therapy guided by intrathoracic blood volume index (ITBVI) on hemodynamic and pulmonary function in patients undergoing elective esophagectomy. Perioperative fluid therapy may influence postoperative physiology and morbidity after esophageal surgery. Definitions of adequate infusion amounts and evident rules for a fluid therapy are missing., Methods: After esophagectomy, 22 patients were randomized either to a restrictive group (RG) with low range of ITBVI (600-800 ml/m2) or a liberal group (LG) with normal ITBVI (800-1000 ml/m2). Infusion regimen was modified twice a day according to transpulmonary thermodilution measurements until the 5th postoperative day. Primary endpoint was paO2/FIO2-ratio. Secondary endpoints were pulmonary function, fluid balance and hemodynamic as well as morbidity., Results: Demographic and surgical details did not differ between both groups. The calculated sample size was not reached. There were no postoperative differences in paO2/FIO2-ratio, ITBVI, hemodynamic parameters, or morbidity either. Cumulative fluid uptake was 4.1 liter less in the RG on the 5th postoperative day (p = 0.01), and pulmonary function was better in these patients (area under curve day 2-7 for forced vital capacity (FVC), forced expiratory volume in one second (FEV1), peak expiratory flow (PEF) each <0.05)., Conclusion: ITBVI guided restrictive infusion therapy yields a lower fluid uptake, but may not result in a difference of clinical relevant parameters. A fluid restriction after esophagectomy should always be combined with hemodynamic monitoring because additional infusions may be required.

Purpose: Contour Transtar procedure for rectal prolapse is a promising technique according to safety and efficacy. One potential surgical problem is failure of the stapler due to the thick rectal wall. In order to evaluate the practicability and the impending limitations of the Contour Transtar technique, we reviewed our data with special respect to the necessity of additional anastomosis suturing., Methods: A prospective analysis of 25 consecutive patients, which underwent Contour Transtar procedure from January 2009 to July 2012, was performed. For statistic analysis, the groups with and without additional suturing of the anastomosis were evaluated according to patient characteristics and surgical outcome., Results: Twenty-five patients, three men and 22 women, underwent transanal Contour Transtar stapling procedure for rectal prolapse. Due to stapling failure, additional suturing of the anastomosis was necessary in 4 of 25 procedures (16%). Age (74.1 vs. 83.1 years) and body mass index (30.8 vs. 22.7 kg/m(2)) were significantly different with and without additional suturing. Operative time was longer (62 vs. 31 min), more cartridges were used (12 vs. 6), and the specimen weight was higher (220 vs. 107 g) in patients with additional suturing. Early postoperative complications were observed in two patients without anastomosis suturing including one patient with bleeding and systemic inflammatory reaction in one case. Postoperative stay did not differ between both groups., Conclusion: Patients with extensive obesity, which present with a substantial rectal prolapse, may need additional suturing of the rectal anastomosis after Contour Transtar stapling. This causes prolonged operative time. However, this does not correlate with complications and it is not related to significant longer hospital stay.

Lack of a uniform definition is responsible for underrecognition of the prevalence of malnutrition and its impact on outcomes in children. A pediatric malnutrition definitions workgroup reviewed existing pediatric age group English-language literature from 1955 to 2011, for relevant references related to 5 domains of the definition of malnutrition that were a priori identified: anthropometric parameters, growth, chronicity of malnutrition, etiology and pathogenesis, and developmental/ functional outcomes. Based on available evidence and an iterative process to arrive at multidisciplinary consensus in the group, these domains were included in the overall construct of a new definition. Pediatric malnutrition (undernutrition) is defined as an imbalance between nutrient requirements and intake that results in cumulative deficits of energy, protein, or micronutrients that may negatively affect growth, development, and other relevant outcomes. A summary of the literature is presented and a new classification scheme is proposed that incorporates chronicity, etiology, mechanisms of nutrient imbalance, severity of malnutrition, and its impact on outcomes. Based on its etiology, malnutrition is either illness related (secondary to 1 or more diseases/injury) or non-illness related, (caused by environmental/behavioral factors), or both. Future research must focus on the relationship between inflammation and illness-related malnutrition. We anticipate that the definition of malnutrition will continue to evolve with improved understanding of the processes that lead to and complicate the treatment of this condition. A uniform definition should permit future research to focus on the impact of pediatric malnutrition on functional outcomes and help solidify the scientific basis for evidence-based nutrition practices.

Objectives: Shiga-toxin producing O157:H7 Entero Haemorrhagic E. coli (STEC/EHEC) is one of the most common causes of Haemolytic Uraemic Syndrome (HUS) related to infectious haemorrhagic colitis. Nearly all recommendations on clinical management of EHEC infections refer to this strain. The 2011 outbreak in Northern Europe was the first to be caused by the serotype O104:H4. This EHEC strain was found to carry genetic features of Entero Aggregative E. coli (EAEC) and extended spectrum β lactamase (ESBL). We report symptoms and complications in patients at one of the most affected centres of the 2011 EHEC O104 outbreak in Northern Germany., Methods: The courses of patients admitted to our hospital due to bloody diarrhoea with suspected EHEC O104 infection were recorded prospectively. These data include the patients' histories, clinical findings, and complications., Results: EHEC O104 infection was confirmed in 61 patients (female = 37; mean age: 44±2 years). The frequency of HUS was 59% (36/61) in our cohort. An enteric colonisation with co-pathogens was found in 57%. Thirty-one (51%) patients were treated with plasma-separation/plasmapheresis, 16 (26%) with haemodialysis, and 7 (11%) with Eculizumab. Patients receiving antibiotic treatment (n = 37; 61%) experienced no apparent change in their clinical course. Twenty-six (43%) patients suffered from neurological symptoms. One 83-year-old patient died due to comorbidities after HUS was successfully treated., Conclusions: EHEC O104:H4 infections differ markedly from earlier reports on O157:H7 induced enterocolitis in regard to epidemiology, symptomatology, and frequency of complications. We recommend a standard of practice for clinical monitoring and support the renaming of EHEC O104:H4 syndrome as "EAHEC disease".

Background: This review aims to present a consensus for optimal perioperative care in colonic surgery and to provide graded recommendations for items for an evidenced-based enhanced perioperative protocol., Methods: Studies were selected with particular attention paid to meta-analyses, randomised controlled trials and large prospective cohorts. For each item of the perioperative treatment pathway, available English-language literature was examined, reviewed and graded. A consensus recommendation was reached after critical appraisal of the literature by the group., Results: For most of the protocol items, recommendations are based on good-quality trials or meta-analyses of good-quality trials (quality of evidence and recommendations according to the GRADE system)., Conclusions: Based on the evidence available for each item of the multimodal perioperative-care pathway, the Enhanced Recovery After Surgery (ERAS) Society, International Association for Surgical Metabolism and Nutrition (IASMEN) and European Society for Clinical Nutrition and Metabolism (ESPEN) present a comprehensive evidence-based consensus review of perioperative care for colonic surgery., (Copyright © 2012 Elsevier Ltd and European Society for Clinical Nutrition and Metabolism.

Habitat suitability (HS) maps are widely used tools in wildlife science and establish a link between wildlife populations and landscape pattern. Although HS maps spatially depict the distribution of optimal resources for a species, they do not reveal the population size a landscape is capable of supporting--information that is often crucial for decision makers and managers. We used a new approach, "maximum clique analysis," to demonstrate how HS maps for territorial species can be used to estimate the carrying capacity, N(k), of a given landscape. We estimated the N(k) of Ovenbirds (Seiurus aurocapillus) and bobcats (Lynx rufus) in an 1153-km2 study area in Vermont, USA. These two species were selected to highlight different approaches in building an HS map as well as computational challenges that can arise in a maximum clique analysis. We derived 30-m2 HS maps for each species via occupancy modeling (Ovenbird) and by resource utilization modeling (bobcats). For each species, we then identified all pixel locations on the map (points) that had sufficient resources in the surrounding area to maintain a home range (termed a "pseudo-home range"). These locations were converted to a mathematical graph, where any two points were linked if two pseudo-home ranges could exist on the landscape without violating territory boundaries. We used the program Cliquer to find the maximum clique of each graph. The resulting estimates of N(k) = 236 Ovenbirds and N(k) = 42 female bobcats were sensitive to different assumptions and model inputs. Estimates of N(k) via alternative, ad hoc methods were 1.4 to > 30 times greater than the maximum clique estimate, suggesting that the alternative results may be upwardly biased. The maximum clique analysis was computationally intensive but could handle problems with < 1500 total pseudo-home ranges (points). Given present computational constraints, it is best suited for species that occur in clustered distributions (where the problem can be broken into several, smaller problems), or for species with large home ranges relative to grid scale where resampling the points to a coarser resolution can reduce the problem to manageable proportions.

Increasingly, land managers seek ways to manage forests for multiple ecosystem services and functions, yet considerable challenges exist in comparing disparate services and balancing trade-offs among them. We applied multi-criteria decision analysis (MCDA) and forest simulation models to simultaneously consider three objectives: (1) storing carbon, (2) producing timber and wood products, and (3) sustaining biodiversity. We used the Forest Vegetation Simulator (FVS) applied to 42 northern hardwood sites to simulate forest development over 100 years and to estimate carbon storage and timber production. We estimated biodiversity implications with occupancy models for 51 terrestrial bird species that were linked to FVS outputs. We simulated four alternative management prescriptions that spanned a range of harvesting intensities and forest structure retention. We found that silvicultural approaches emphasizing less frequent harvesting and greater structural retention could be expected to achieve the greatest net carbon storage but also produce less timber. More intensive prescriptions would enhance biodiversity because positive responses of early successional species exceeded negative responses of late successional species within the heavily forested study area. The combinations of weights assigned to objectives had a large influence on which prescriptions were scored as optimal. Overall, we found that a diversity of silvicultural approaches is likely to be preferable to any single approach, emphasizing the need for landscape-scale management to provide a full range of ecosystem goods and services. Our analytical framework that combined MCDA with forest simulation modeling was a powerful tool in understanding trade-offs among management objectives and how they can be simultaneously accommodated.

Background: Heart rate variability (HRV) is a sensitive marker of altered sympathetic-parasympathetic function and is reduced in inflammation, illness, and trauma. The effect of major abdominal surgery on the course of HRV parameters is still an issue requiring further investigation., Materials and Methods: A prospective, observational study including 40 consecutive patients undergoing elective colorectal surgery under "fast-track" perioperative management. Time and frequency domain parameters of HRV were measured 1 day prior to operation and on days 1-5 postoperatively. General and surgical complications as well as the course of leucocytes and C-reactive protein (CRP) were documented and correlated to the HRV measurements., Results: Time domain parameters of HRV showed a significant decrease compared to the preoperative values on postoperative day 1 and returned to baseline on day 2, demonstrating impaired autonomic regulation in the early postoperative period. No correlation to complications or course of leukocytes or CRP was significant in our study., Conclusions: Colorectal resections significantly influence the HRV course. The autonomic regulation is reduced in the early postoperative time and all parameters return to baseline until the third day.

The term fast-track describes the combination of several perioperative evidence-based measures to form a clinical pathway. The primary aim of fast-track is to optimize organ function after surgery in order to avoid general morbidity. At the same time patient recovery is dramatically enhanced and discharge from hospital is possible much earlier than with traditional perioperative care. This article describes the author's experience in implementing a fast-track program for elective colonic resection. It shows the current status of scientific evaluation of the fast-track concept and discusses typical obstacles during introduction of fast-track into the clinical routine in Germany.

Purpose: Laparoscopic assisted sigmoid resection (LASR) has become a widely accepted procedure in colorectal surgery. In the last decade, numerous variations of surgical details have been established. In order to demonstrate a feasible technique, this video is provided., Methods: LASR is performed using four ports. The first port is inserted via open access by a minilaparotomy in the right paraumbilical region. Two ports are sited in the right lower abdomen, including one 12-mm port in the following incision above the pubic symphysis. The forth port is inserted in the left upper abdomen. The procedure starts with the removal of adhesions, the peritoneal incision is performed medially, and a medial to lateral approach to the mesocolon and the inferior mesenteric artery (IMA) is carried out. After identifying the left ureter, the IMA is either clipped or sealed about 1.5 to 2 cm from the origin in order to preserve the autonomous plexus. Then dissection is continued on Gerota's fascia. After lifting the rectosigmoid, dissection is continued in the avascular plane until the mesentery of the upper rectum is mobilized. Then the remaining lateral adhesions are dissected with preservation of the gonadal vessels and the left ureter. The distal resection line is always in the upper rectum, which is easily identified by the lack of tenia. After sealing the mesorectum, the rectum is dissected using a linear stapler. Thereafter, a minilaparotomy above the pubic symphysis is performed and a device for protection and retraction of the wound is inserted. Dissection of the mesosigmoid and the descending colon is carried out extracorporally. The anvil of a circular stapling device is inserted in the descending colon, which is then returned into the peritoneal cavity. Running sutures closes the incision, and the anastomosis is carried out laparoscopically in a "double stapling" technique., Conclusion: The video describes the efficacy and technical feasibility of laparoscopic surgery for diverticular disease and demonstrates its effect regarding perioperative morbidity and functional outcome.

Purpose: Elective laparoscopic sigmoid resection (LSR) for symptomatic diverticular disease is supposed to have significant short-term advantages compared to open surgery (open sigmoid resection (OSR)). This opinion is rather based on inferences from trials on colonic resections for malignant diseases or minor laparoscopic surgery. This randomized controlled trial was conducted to compare quality of life as well as morbidity and clinical outcome after LSR vs. OSR following a midterm follow-up period., Methods: Patients presenting with a symptomatic sigmoid diverticular disease stage II/III (Stock/Hansen) were randomly allocated to LSR or OSR in a prospective multicenter trial. Endpoints included the quality of life assessed with a standardized questionnaire, postoperative mortality, and complications within the follow-up of 12 months after operation., Results: A total of 143 patients randomized between 2005 and 2008 in 12 centers could be analyzed. The recruitment was aborted for nonachievement of the planned sample size. Seventy-five patients were allocated to LSR, and 68 received OSR. Nine operations were converted to OSR (9%) and analyzed as intention to treat. Groups were comparable for age, gender, body mass index, comorbidity, and indication for surgery. Operation time was longer for LSR (p < 0.001). Quality of life did not differ between LSR and OSR, either during the early postoperative course or after 12 months (p = 0.172). Also, mortality and morbidity, including subgroups of major and minor morbidity, were compared., Conclusion: LSR was not superior to OSR regarding postoperative quality of life and incidence of complications in this trial.

Rapidly changing landscapes have spurred the need for quantitative methods for conservation assessment and planning that encompass large spatial extents. We devised and tested a multispecies framework for conservation planning to complement single-species assessments and ecosystem-level approaches. Our framework consisted of 4 elements: sampling to effectively estimate population parameters, measuring how human activity affects landscapes at multiple scales, analyzing the relation between landscape characteristics and individual species occurrences, and evaluating and comparing the responses of multiple species to landscape modification. We applied the approach to a community of terrestrial birds across 25,000 km(2) with a range of intensities of human development. Human modification of land cover, road density, and other elements of the landscape, measured at multiple spatial extents, had large effects on occupancy of the 67 species studied. Forest composition within 1 km of points had a strong effect on occupancy of many species and a range of negative, intermediate, and positive associations. Road density within 1 km of points, percent evergreen forest within 300 m, and distance from patch edge were also strongly associated with occupancy for many species. We used the occupancy results to group species into 11 guilds that shared patterns of association with landscape characteristics. Our multispecies approach to conservation planning allowed us to quantify the trade-offs of different scenarios of land-cover change in terms of species occupancy., (Conservation Biology © 2011 Society for Conservation Biology.

Background: Various sequelae which might lead to reintervention have been described after stapled rectal mucosectomy for hemorrhoids. One potential treatment modality for persistent complaints after stapled hemorrhoidopexy (SHP) or stapling for rectocele is the so-called agraffectomy (removal of the retained staples). This treatment option means a further procedure that can range from removal of the staples through the anoscope to removal of the entire staple line with the associated scar tissue., Methods: In order to review the published literature, we conducted a search on Medline, Pubmed, and Embase using different terms for "agraffectomy.", Results: Overall, fourteen reports were found, dealing with agraffectomy for various conditions after low rectal stapling for hemorrhoids or rectocele. Agraffectomy is a rarely mentioned treatment option for conditions after SHP. In rectal stenosis with complete occlusion of the rectal lumen, the removal of the stenotic anastomosis and remaining staples seems to be reasonable. The same can be said of the removal of retained staples for rectal bleeding or in order to avoid penile injuries in anal intercourse. In contrast, the collected published reports on agraffectomy in this review only provide low-level evidence that this procedure provides relief for other problems such as incontinence or chronic pain., Conclusions: There is no clear evidence that agraffectomy is indicated if not in case of rectal stenosis and hemorrhage caused by the staples.

Scientific studies have proven without doubt that an optimized perioperative pain therapy will improve patient comfort, reduce postoperative complications, enhance postoperative recovery and shorten the length of postoperative hospital stay. It is necessary to incorporate the acute pain therapy into a perioperative multimodal and interdisciplinary therapeutic concept. Local or regional anesthesia will provide the best analgesic effect after surgery and should be considered in all patients. Optimal treatment of patients with peripheral nerve blocks, spinal or epidural analgesia should be treated by a specialized acute pain service. However, only 15-20% of all surgical cases will be taken care of by such a pain service. Therefore, most surgical patients will only receive adequate analgesia if surgeons are familiar with the principles of postoperative pain therapy. Regular assessment of pain perception is the cornerstone of optimized pain therapy. Furthermore, pain assessment will allow the administration and to some extent dosage of analgesic therapy to be delegated to nursing personnel.
