RESUMEN
BACKGROUND: Carcinoma of ampulla of Vater are rare tumours of the GI-tract with an improved prognosis compared to other periampullary tumours. Analysis of survival and prognostic factors are limited due to the low incidence of the carcinoma. The intention of this study in patients with papillary carcinoma was to evaluate short- and long-term survival and to identify prognostic factors for pancreatectomy and reconstruction using pancreatogastrostomy as treatment of carcinoma of Vater's ampulla. PATIENTS AND METHODS: Between 1989 and 2008 76 patients with a carcinoma of the ampulla of Vater were treated by oncological resection followed by pancreatogastrostomy. Various factors such as demographics, perioperative factors, histopathological findings as well as short- and long-term survival were evaluated retrospectively. Data were analysed statistically using Kaplan-Meier estimates of survival with log-rank test and uni- and multivariate analysis with Cox regression. RESULTS: The overall 5-year survival was 46â%, the 10-year survival 26â% for resected patients. By univariate analysis we could demonstrate that lymph node metastasis is the only predictor for outcome. In the multivariate analysis, age, sex, grading and especially lymph node status were a significant predictor for the survival of patients. CONCLUSION: In the current patient cohort lymph node status was the most important independent predictor of outcome after resection of carcinoma of Vater's papilla.

BACKGROUND: In recent years there has been a significant increase of surgical procedures worldwide. Perioperative complication occurred in approximately 10â%, mortality was about 0.5â%. Half of these adverse events were considered to have been preventable. With the introduction of a perioperative checklist by the WHO in 2008, a significant reduction of morbidity and mortality could be achieved. The aim of this study was to investigate the success of the implementation process of the checklist at a maximum care hospital over a three-year period and to expose and analyse any occurring issues. PATIENTS AND METHODS: At various time points (introduction phase, five months, one year and three years after implementation) a total of 358 operations was investigated. First the presence and the handling of the checklist were investigated followed by an analysis of possible influencing factors on the processing. To examine a potential perioperative malpractice, three typical perioperative errors known from the literature on patient safety were analysed. RESULTS: The presence of the checklist improved significantly during the study. With the exception of the first column (signed by ward nurse) the checklist was processed more often among the participants (anaesthesia nurse, anaesthesia physician, surgeon) over the time. However the "sign out" column edited by the surgeon at the end of the operation fell below expectations. In addition to the duration after implementation the level of experience of the surgeon was a relevant factor for a properly completed checklist. During the study a malpractice was found in two cases, a checklist could not be detected. CONCLUSION: Within the study we could demonstrate the difficulties of introducing a surgical checklist at a maximum care hospital. Therefore involved nursing or medical staff must be aware of the usefulness of the checklist and should be motivated to use it. In addition, periodical lectures, training courses and role modelling of nursing and medical staff are required. The objective must be to establish the checklist into daily routine as it is a simple and efficient tool to reduce perioperative morbidity and mortality.

BACKGROUND: Posthepatectomy liver failure (PHLF) is one of the most serious complications after major liver resections and an important factor in terms of perioperative morbidity and mortality. Despite many advances in the understanding and grading of PHLF, the definitions found in literature are very heterogeneous, which complicates the identification of high-risk patients. In this study we analysed the results of extended liver resections and potential risk factors for PHLF based on patient data derived from our tertiary referral centre. The aim of the study was to gain an overview of the essential aspects in the prevention of PHLF combined with key intraoperative issues and postoperative treatment strategies. METHODS: We analysed data from 202 patients who underwent extended elective liver resections at our centre between April 1989 and September 2009 (135 right hemihepatectomies, 39 left hemihepatectomies, 28 right trisectionectomies). According to Balzan's "50/50 criteria", PHLF was defined as prothrombin time (PT) < 50â% combined with serum bilirubin (SB) > 50 micromol/L on postoperative day (POD) 5 or as death due to primary or secondary liver failure. RESULTS: Thirty-day mortality and overall in-hospital mortality were 4.95 and 8.91â%, respectively. Twenty-eight (14â%) patients developed PHLF and 16 (57â%) patients died. Compared to patients with normal postoperative liver function, several significant pre- and intraoperative factors for PHLF were identified, e.g. primary malignant liver tumour (p < 0.001), extended liver resection (p < 0.001), time of surgery (p < 0.001) and intraoperative transfusion of packed RBC (p < 0.02) or FFP (p < 0.001). CONCLUSION: Although progress has been made in hepatobiliary surgery, PHLF remains a serious complication, especially after extended liver resections. Careful, optimised preoperative risk stratification is required to identify patients at risk for PHLF.

Postoperative ileus (POI) is defined as a transient episode of impaired gastrointestinal motility after abdominal surgery, which prevents effective transit of intestinal contents or tolerance of oral intake. This frequent postoperative complication is accompanied by a considerable increase in morbidity and hospitalisation costs. The aetiology of POI is multifactorial. Besides a suppression of peristalsis by inhibitory neuronal signalling and administration of opioids, particularly in the prolonged form, immunological processes play an important role. After surgical trauma, resident macrophages of the muscularis externa (ME) are activated leading to the liberation of proinflammatory mediators and a spreading of the inflammation along the entire gastrointestinal tract. To date, no prophylaxis or evidence-based single approach exists to treat POI. Since none of the current treatment approaches (i.e., prokinetic drug treatment) has provided a benefit in randomised trials, immunoregulatory interventions appear to be more promising in POI prevention or treatment. The present contribution gives an overview of immunological mechanisms leading to POI focusing on current and future therapeutic and prophylactic approaches.

BACKGROUND: The success of abdominal cancer surgery depends not only on the surgery itself but is influenced by the overall perioperative management. Given the multitude of perioperative measures and the ever-increasing number of studies on perioperative management, it is difficult to keep track and provide evidence-based perioperative management. The planned guideline on perioperative management will review the existing evidence and derive treatment recommendations. METHODS: The processing of the evidence is carried out by 6 working groups according to an 8-step scheme: after drafting the guideline questions in PICO format (1), a systematic literature search is carried out (2), and the records found are screened by two independent reviewers from the coordination team. Subsequently, the full texts of the potentially relevant articles are made available to the working groups for full text screening (3). All articles to be included are reviewed for methodological quality (4) before summary of findings tables are generated (5). In line with the GRADE approach, confidence in the evidence is assessed (6) before a recommendation is derived from the evidence, using a modified GRADE Evidence to Decision Framework (7). Finally, all recommendations are compiled and agreed within the guideline group (8). DISCUSSION: Guidelines serve as foundation for therapy decisions in everyday clinical practice and should therefore be based on up-to-date research results. However, while primary studies and systematic reviews are critically reviewed for their methodological quality, the process of guideline development is often not comprehensible. A protocol with predefined methodology should therefore create transparency and strengthen confidence in the recommendations. TRIAL REGISTRATION: The guideline is registered in the AWMF (Association of the Scientific Medical Societies) Guideline Register (088-010OL).
RESUMEN
BACKGROUND: Surgical site infections (SSIs), mainly caused by Staphylococcus aureus, pose a significant economic burden in Europe, leading to increased hospitalization duration, mortality, and treatment costs, particularly with drug-resistant strains such as meticillin-resistant S. aureus. AIM: To conduct a case-control study on the economic impact of S. aureus SSI in adult surgical patients across high-volume centres in France, Germany, Spain, and the UK, aiming to assess the overall and procedure-specific burden across Europe. METHODS: The SALT study is a multinational, retrospective cohort study with a nested case-control analysis focused on S. aureus SSI in Europe. The study included participants from France, Germany, Italy, Spain, and the UK who underwent invasive surgery in 2016 and employed a micro-costing approach to evaluate health economic factors, matching S. aureus SSI cases with controls. FINDINGS: In 2016, among 178,904 surgical patients in five European countries, 764 developed S. aureus SSI. Matching 744 cases to controls, the study revealed that S. aureus SSI cases incurred higher immediate hospitalization costs (8,810), compared to controls (6,032). Additionally, S. aureus SSI cases exhibited increased costs for readmissions within the first year post surgery (7,961.6 versus 5,298.6), with significant differences observed. Factors associated with increased surgery-related costs included the cost of hospitalization immediately after surgery, first intensive care unit (ICU) admission within 12 months, and hospital readmission within 12 months, as identified through multivariable analysis. CONCLUSION: The higher rates of hospitalization, ICU admissions, and readmissions among S. aureus SSI cases highlight the severity of these infections and their impact on healthcare costs, emphasizing the potential benefits of evidence-based infection control measures and improved patient care to mitigate the economic burden.

Clinical evidence suggests that recurrent acute cellular rejection (ACR) may trigger chronic rejection and impair outcome after intestinal transplantation. To test this hypothesis and clarify underlying molecular mechanisms, orthotopic/allogenic intestinal transplantation was performed in rats. ACR was allowed to occur in a MHC-disparate combination (BN-LEW) and two rescue strategies (FK506monotherapy vs. FK506+infliximab) were tested against continuous immunosuppression without ACR, with observation for 7/14 and 21 days after transplantation. Both, FK506 and FK506+infliximab rescue therapy reversed ACR and resulted in improved histology and less cellular infiltration. Proinflammatory cytokines and chemotactic mediators in the muscle layer were significantly reduced in FK506 treated groups. Increased levels of CD4, FOXP3 and IL-17 (mRNA) were observed with infliximab. Contractile function improved significantly after FK506 rescue therapy, with a slight benefit from additional infliximab, but did not reach nontransplanted controls. Fibrosis onset was detected in both rescue groups by Sirius-Red staining with concomitant increase of the fibrogenic mediator VEGF. Recovery from ACR could be attained by both rescue therapy regimens, progressing steadily after initiation of immunosuppression. Reversal of ACR, however, resulted in early stage graft fibrosis. Additional infliximab treatment may enhance physiological recovery of the muscle layer and enteric nervous system independent of inflammatory reactions.

PURPOSE: Postoperative ileus (POI) is an iatrogenic complication of abdominal surgery, mediated by a severe inflammation of the muscularis externa (ME). Previously, we demonstrated that intravenous application of the tetravalent guanylhydrazone semapimod (CNI-1493) prevents POI, but the underlying mode of action could not definitively be confirmed. Herein, we investigated the effect of a novel orally active salt of semapimod (CPSI-2364) on POI in rodents and distinguished between its inhibitory peripheral and stimulatory central nervous effects on anti-inflammatory vagus nerve signaling. METHODS: Distribution of radiolabeled orally administered CPSI-2364 was analyzed by whole body autoradiography and liquid scintillation counting. POI was induced by intestinal manipulation with or without preoperative vagotomy. CPSI-2364 was administered preoperatively via gavage in a dose- and time-dependent manner. ME specimens were assessed for p38-MAP kinase activity by immunoblotting, neutrophil extravasation, and nitric oxide production. Furthermore, in vivo gastrointestinal (GIT) and colonic transit were measured. RESULTS: Autoradiography demonstrated a near-exclusive detection of CPSI-2364 within the gastrointestinal wall and contents. Preoperative CPSI-2364 application significantly reduced postoperative neutrophil counts, nitric oxide release, GIT deceleration, and delay of colonic transit time, while intraoperatively administered CPSI-2364 failed to improve POI. CPSI-2364 also prevents postoperative neutrophil increase and GIT deceleration in vagotomized mice. CONCLUSIONS: Orally administered CPSI-2364 shows a near-exclusive dispersal in the gastrointestinal tract and effectively reduces POI independently of central vagus nerve stimulation. Its efficacy after single oral dosage affirms CPSI-2364 treatment as a promising strategy for prophylaxis of POI.

PURPOSE: The fast-track (FT) concept is a multimodal, interdisciplinary approach to perioperative patient care intended to reduce postoperative complications. Despite good evidence implementation seems to need improvement, whereby almost all studies focused on the implementation of surgical modules regardless of the interdisciplinary aspect. Adherence to the anesthesiological measures (prehabilitation, premedication, volume and temperature management, pain therapy), on the other hand, has been insufficiently studied. To assess the status quo a survey on the implementation of anesthesiological FT measures was conducted among members of the German Society of Anesthesiology and Intensive Care Medicine (DGAI) to analyze where potential for improvement exists. METHODS: Using the SurveyMonkey® online survey tool, 28 questions regarding perioperative anesthesiological care of colorectal surgery patients were sent to DGAI members in order to analyze adherence to FT measures. RESULTS: While some of the FT measures (temperature management, PONV prophylaxis) are already routinely used, there is a divergence between current recommendations and clinical implementation for other components. In addition to premedication, interdisciplinary measures (prehabilitation) and measures that affect multiple interfaces (operating theatre, recovery room, ward), such as volume management or perioperative pain management, are particularly affected. CONCLUSION: The anesthesiological recommendations of the FT concept are only partially implemented in Germany. This particularly affects the interdisciplinary components as well as measures at the operating theatre, recovery room and ward interfaces. The establishment of an interdisciplinary FT team and interdisciplinary development of SOPs can optimize adherence, which in turn improves the short-term and long-term outcome of patients.

BACKGROUND: Indocyanine green (ICG) fluorescence imaging is increasingly being used in various areas of abdominal surgery. The constant improvement in the technology enables easy intraoperative use and progressively influences operative decision-making, also in robotically assisted colorectal surgery. OBJECTIVE: Summation of current evidence on the use of ICG fluorescence imaging in robotically assisted colorectal surgery. MATERIAL AND METHODS: The assessment of evidence is based on a comprehensive literature search (PubMed). RESULTS: First individual studies (feasibility, case matched, prospective cohort, multicenter phase II, single center randomized controlled study/trial) showed a significant reduction in the incidence of anastomotic leakage (AL) after colorectal anastomosis through the use of ICG fluorescence angiography (FA, 9.1% vs. 16.3%; pâ¯= 0.04). First feasibility studies demonstrated lymph node detection or navigation as well as ureter visualization. CONCLUSION: The ICG-FA reliably detects tissue perfusion, quickly and effectively with few side effects. It can influence intraoperative decision-making and reduce AL rates. In addition, patients may be offered more precise tumor therapy via ICG sentinel lymph node (SLN) detection and lateral pelvic lymph node (LPN) mapping and navigation. Iatrogenic lesions, such as ureteral injuries can be sufficiently prevented by appropriate visualization; however, valid data in order to be able to derive standardized operative consequences require further convincing multicenter, randomized controlled trials (mRCT).

An intestinal stoma (greek στá½µα, stoma: mouth, opening) is a surgically created opening of a gut section through the abdominal wall, which serves as an artificial intestinal exit for excretion of feces (synonym preternatural anus). A stoma of the gastrointestinal (GI) tract is often surgically created at the distal small intestine (ileostomy) and the colon (colostomy). Temporary or permanent deviation of fecal excretion may be required to treat various pathological conditions (e.g. congenital anomalies, ileus, inflammatory bowel diseases, posttraumatic, diverticulitis, colorectal malignancy). The creation of an end vs. a loop stoma is technically different. To achieve sufficient patient satisfaction close collaboration between surgeons, professional stoma care with guidance and training as well as support from self-help groups are required. In this way serious stoma-related complications can be avoided.

BACKGROUND: Mechanical bowel obstruction is a common condition in geriatric patients in the emergency department. It accounts for up to 50% of all emergency surgeries in the elderly. In recent years, diagnosis and treatment of mechanical bowel obstruction has improved, but little is known whether elderly patients benefit from modern treatment approaches. OBJECTIVE: The aim of the work is to generate knowledge about possible improvement of diagnosis and treatment of mechanical bowel obstruction in the elderly. METHODS: A retrospective review of 132 patients was performed comparing geriatric (>80 years of age) and nongeriatric patients (50-70 years of age) admitted with mechanical bowel obstruction. Etiology, time from first contact to operation, bowel resection rate and morbidity/mortality were compared. Data analysis included Fisher's test and Student ttest. RESULTS: In patients under 70 years of age it took 18.23⯱ 0.79â¯h from first contact until laparotomy in the operating room (OR) vs. 43.38⯱ 12.08â¯h in patients above 80 years of age (pâ¯= 0.0111). In 58.9% of geriatric patients, resection of bowel was necessary, while only 35.3% of <70-year-old patients needed bowel resection (pâ¯= 0.0401). In all, 50% of geriatric patients experienced major complications (Dindo/Clavien >IIIB) vs. only 12.7% of 50- to 70-year-old patients (pâ¯= 0.0002). Postoperative stay in the intensive care unit was significantly prolonged in geriatric patients compared to younger patients (93.97⯱ 17.36â¯h vs. 26.11⯱ 3.73â¯h, pâ¯< 0.0001). CONCLUSIONS: Time from first contact in the emergency department until laparotomy in the OR is prolonged in geriatric patients, leading to a higher probability of bowel resection with greater morbidity and mortality. Diagnostics should be intensified and accelerated in geriatric patients. Emergency surgery should be considered earlier.

BACKGROUND: Although only a low percentage of abdominal surgical interventions are performed using a robotic platform, the total number has significantly increased in recent years and robotic surgery (RS) is no longer limited only to university hospitals. Despite the increasing popularity and many innovations in the field of robotic surgery with new devices, the data situation is confusing. OBJECTIVE: This review deals with the current areas of application of robotic devices in abdominal surgery and whether there are any advantages compared to laparoscopic surgery (LS). MATERIAL AND METHODS: The current international literature was evaluated and is critically discussed with a particular focus on clinical trials. RESULTS: While the disadvantages include high costs and longer times of surgery, the advantages are a stable optical platform and the high mobility even in confined spaces; however, no high-quality, randomized controlled trial in abdominal surgery is currently available that could demonstrate an advantage of RS compared to LS. CONCLUSION: Although no clear advantages of RS for the patients could so far be demonstrated, it seems to be at least equivalent to LS. Undisputed is the level of comfort for the surgeon. Once the costs of RS can be reduced, LS will probably be replaced for most indications.

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.

Postoperative peritoneal adhesions are common sequelae of abdominal surgery. Acute as well as chronic complications, including bowel obstruction, abdominal pain and infertility can arise from adhesion formation. So far, the only reliable treatment is surgical adhesiolysis, which in turn is accompanied by an increased risk of adhesion recurrence. Despite significant progress in modern perioperative medicine, only limited prophylactic approaches are available and atraumatic surgery is still the most important factor.Current research concepts focus on two major antiadhesion strategies: firstly, the intraoperative placement of mechanical barriers and secondly novel immunomodulation concepts. Clinical data about the use of antiadhesive barriers show a heterogeneous outcome. Promising data have arisen from the immunomodulatory approaches and now require a step-up development from experimental to clinical trial level.The present review gives a short overview about the current research on the pathophysiology and prevention of peritoneal adhesions. The promising data are encouraging and require realization of carefully designed prospective clinical trials.

BACKGROUND: The repair of complicated abdominal hernias remains a challenging problem. The components separation technique introduced by Ramirez et al. is an increasingly popular method for autogenous reconstruction of the abdominal wall, especially in combination with epifascial mesh reinforcement. PATIENTS AND METHODS: In a retrospective study carried out at a university hospital, 40 consecutive patients between 2002 and 2010 were analyzed. RESULTS: Indications for abdominal reconstruction were fascial defects after secondary healed laparostoma in 22 patients (55%) and fascial defects combined with colostomy reversal after a Hartmann procedure in 10 patients (25%). A total of 9 wound infections (22.5%) occurred and 10 hernia recurrences (10/36 patients) were identified in the follow-up (mean 3.8 years, range 1-9 years). Reconstructions with mesh reinforcement resulted in a lower rate of recurrences (19% with mesh vs 40% without mesh). CONCLUSIONS: The components separation technique, in combination with epifascial mesh reinforcement as appropriate, is the procedure of choice for most complicated abdominal wall hernias. Therefore, each visceral surgeon should be able to perform this method. Recurrence rates depend on the underlying disease of the patient and the complexity of the hernia.

In comparison to the conventional technique of incisional or umbilical hernia repair with sublay mesh augmentation, incisional hernias in obese patients can be surgically treated with minor surgical trauma by laparoscopic intraperitoneal onlay mesh (IPOM) repair. However, although shortened operation time, hospital stay and faster postoperative reconvalescence might be possible with IPOM repair, the economic calculation including mesh costs is significantly higher. In this study the two operation techniques were compared and the perioperative advantages and disadvantages of both methods were analyzed based on the German diagnosis-related groups (DRG) system.
