[Vascularsurgical Long-term Outcome - Comparison of Orthotopic and Extraanatomic Reconstructions in Unilateral Occlusions of Iliac Artery over 10 Years]. / Gefäßchirurgische Langzeitergebnisse ­ Vergleich orthotoper und extraanatomischer Rekonstruktionen bei unilateralen Beckenachsenverschlüssen über 10 Jahre.

In PAOD, several vascular regions are usually affected, the pelvic axis in 35% of cases. Interventional-radiological/endovascular or hybrid interventions have been established for recanalization, so that bypass procedures are increasingly taking a back seat, but are not losing their importance.To study unilateral iliac artery occlusions (inclusion criterion) that were repaired either by implantation of an orthotopic or extraanatomic bypass (oBP/eaBP).Over a defined period of time, the rate of open vessel, complications (frequency, type, severity) to characterize morbidity and mortality as well as the extent of clinical improvement after BP implantation were analyzed in a clinical-systematic, single-center observational study (for vascular surgical quality assurance and contribution to vascular medical-clinical health care research). The study method was not explicitly based on the STROBE criteria, but essentially corresponds to them.Over 10 years, 122 PAOD patients (50% in stage IIb-stage III and IV equally distributed; mean age: 63 [range, 44-87] years; majority ASA III) were included with the same number of reconstructions: 71 patients received an eaBP ("crossover"), 51 patients an iliacofemoral (orthotopic - oBP) bypass (neither significant difference regarding frequency nor number of risk factors per patient).The oBP is not superior to eaBP with regard to the analysis parameters of openness, complication rate and mortality. Furthermore, extraanatomic revascularization does not have to be reserved for polymorbid patients only.

[Value and Role of Obesity and Metabolic Surgery in the Study of Human Medicine, Academic Teaching and Advanced Training]. / Bedeutung der Adipositas- und metabolischen Chirurgie im humanmedizinischen Studium, in der akademischen Lehre und Weiterbildung.

In teaching, obesity and metabolic surgery play only a limited role. However, due to the rapidly increasing number of surgical interventions, communication of knowledge in the study of human medicine as well as in gastroenterological and surgical residency (general and abdominal surgery) is required.Narrative review. · Currently, lectures on obesity and metabolic surgery do not belong to the current surgical curriculum of human medicine at all University Medical Schools, which needs to be absolutely established step by step - based on their topicality and importance in the clinical spectrum of clinical care.. · This rapidly developing special area of abdominal surgery is characterized by specific and diverse interdisciplinarity.. · Multimorbidity, changes in resorption mechanisms but also psychological changes have a substantial impact on the indication and patient outcome.. · The increase in endoscopic, surgical and also robotic interventions and surgical methods in this special field requires a broad knowledge of all surgical disciplines in intervention preparation, perioperative and follow-up management of obesity-associated basic diagnosis. This objective is important even in the study of human medicine and further advanced training.. The inclusion of such complex contents on obesity and metabolic surgery into surgical teaching and into residency of general and abdominal surgery is essential to be future-oriented and prepared for the development of the discipline.

The Pancreas as a Target of Metastasis from Renal Cell Carcinoma: Is Surgery Feasible and Safe? A Single-Center Experience in a High-Volume and Certified Pancreatic Surgery Center in Germany.

Background: Secondary malignant tumors of the pancreas are rare, representing 2-5% of all pancreatic malignancies. Nevertheless, the pancreas is one of the target organs in cases of metastatic clear cell renal cell carcinoma (CCRCC). Additionally, recurrent metastasis may occur. Surgical resection remains the best and prognostically most favorable therapeutic option in cases of solitary pancreatic metastasis. Aim: To review retrospectively the clinical tumor registry of the University Hospital of Magdeburg, Germany, for this rare entity, performing a clinical systematic single-center observational study (design). Methods: A retrospective cohort analysis of consecutive patients who had undergone pancreatic resection for metastatic CCRC was performed in a single high-volume certified center for pancreatic surgery in Germany from 2010 to 2022. Results: All patients (n = 17) included in this study had a metachronous metastasis from a CCRCC. Surgery was performed at a median time interval of 12 (range, 9-16) years after primary resection for CCRCC. All 17 patients were asymptomatic at the time of diagnosis. Three of those patients (17.6%) presented with recurrent metastasis in a different part of the pancreas during follow-up. In a total of 17 patients, including those with recurrent disease, a surgical resection was performed; Pancreatoduodenectomy was performed in 6 patients (35%); left pancreatectomy with splenectomy was performed in 7 patients (41%). The rest of the patients underwent either a spleen-preserving pancreatic tail resection, local resection of the tumor lesion or a total pancreatectomy. The postoperative mortality rate was 6%. Concerning histopathological findings, seven patients (41%) had multifocal metastasis. An R0 resection could be achieved in all cases. The overall survival at one, three and five years was 85%, 85% and 72%, respectively, during a median follow-up of 43 months. Conclusions: CCRC pancreatic metastases can occur many years after the initial treatment of the primary tumor. Surgery for such a malignancy seems feasible and safe; it offers very good short- and long-term outcomes, as indicated. A repeated pancreatic resection can also be safely performed.

Uncommon diagnosis of multinodular goiter - isolated extrapulmonary manifestation of sarcoidosis in thyroid gland (scientific case reports).

AIM: By means of the scientific description of two uncommon cases who underwent. surgical resection of multinodous goiter and following histopathological investigation revealing isolated extrapulmonary manifestation of sarcoidosis, this uncommon diagnosis including symptomatology, clinical findings, diagnostic and therapeutic management is to be illustrated. CASE DESCRIPTIONS: Diagnostics: Scintigraphy of the thyroid gland with a left-thyroid cold node; ultrasound-guided puncture (cytological investigation, non-suspicious). THERAPY: Elective thyroidectomy with no macroscopic anomalies und no abnormal aspects with regard to surgical tactic and technique. Histopathological investigation: Complete resection specimen of the thyroid gland with granulomatous inflammation consistent with sarcoidosis. CLINICAL COURSE: Uneventful with no further manifestations of sarcoidosis in the following diagnostics. DIAGNOSTICS: Ultrasound, inhomogeneous node (37×30×35 mm) of the right thyroideal gland with echo-poor parts and peripheral vascularization; scintigraphy showing marginally compensated unifocal autonomy of the thyroid gland (laboratory parameters, increased serum level of thyroglobulin [632 ng/mL]). THERAPY: Planned right hemithyroidectomy with confirmed nodous structure of thyroid parenchyma, without suspicious lymph nodes. Histopathological investigation: 33-mm follicular, nodular, encapsulated structure of thyroid parenchyma (diagnosed as follicular adenoma); 2nd opinion: low-grade differentiated carcinoma of thyroid gland with angioinfiltrating growth and granulomatous inflammation of sarcoidosis type. Procedural intent: After tumor-board consultation, completing thyroidectomy was performed within a 5-weeks interval (pT2 pN0[0/1] V1 L0 G3 R0) with subsequent ablating radio'active iodine therapy; 18 F-FDG-PET-CT (several atypical infiltrates within the right upper lobe of the lung) and bronchoscopy with no detection of further manifestation of sarcoidosis. CONCLUSION: Sarcoidosis is considered a rare granulomatous multi-locular, systemic disease of not completely known etiopathogenesis with substantial heterogeneity. In most cases, it is associated with the lung, but which can become manifest in various organs. Frequently, extrapulmonary manifestations are usually detected as histological findings by coincidence, which require further investigation to find out additional manifestations as well as to exclude florid infection or other granulomatous processes (clarifying competently differential diagnosis). Therapy is only indicated in symptomatic organ manifestations, taking into account the high rate of spontaneous healing and possible side effects.

[Interdisciplinary surgical spectrum in cooperation of abdominal surgery and gynecology : What must the (general/abdominal) surgeon know?] / Interdisziplinär ausgerichtetes Operationsspektrum in Kooperation von Viszeralchirurgie und Gynäkologie : Was sollte der (Allgemein­/Viszeral­)Chirurg wissen?

AIM: This short overview aims to concisely outline the most important gynecological issues from a predominantly operative point of view, which could also be relevant for general and abdominal surgeons as well as important gynecological aspects of primarily visceral surgical pathologies. METHOD: Narrative review on the topic of interdisciplinary cooperation in gynecological/general and abdominal surgery through the use of PubMed® as well as the Cochrane Library with search terms, such as "operative profile of abdominal surgery and gynecology", "interdisciplinary surgery aspects of gynecology/abdominal surgery" as well as "interdisciplinary surgical approach-surgical complication". RESULTS (MAIN POINTS): As the close anatomical relationship suggests, numerous primarily gynecological pathologies can also occur in abdominal organs. Likewise, predominantly surgical pathologies can result in involvement of gynecological organs. This can make an intraoperative collaboration necessary. In addition, as a result of diagnostic uncertainty or within the context of complications, interdisciplinary collaboration can also be required preoperatively and postoperatively. Multidisciplinary knowledge as well as close cooperation of the involved specialties can improve the outcome of affected patients. CONCLUSION: Many pathologies extend not only to the boundaries of an individual discipline but can also affect physiological systems exceeding those limits. Therefore, for an optimal treatment it is necessary to be aware of such aspects of the diseases and to establish structured procedures for interdisciplinary cooperation.

[Against the mental stress-Resilient work in surgery]. / Wider psychische Belastungen ­ resilientes Arbeiten in der Chirurgie.

BACKGROUND: Surgery represents a challenging medical discipline. AIM: This article focuses on psychological stress in surgery and explains resilience as a protective factor against the consequences of psychological stress, based on selected literature references and own relevant clinical experiences. In this context, the sense of coherence, social support and self-efficacy expectation are discussed in more detail as resilience factors. METHOD: Narrative review. RESULTS (CORNER POINTS): Surgery is classified as a challenging medical subspecialty with a high reputation but associated with diverse and varied physical and psychological stress factors. Stress factors differ individually in terms of requirements (can be overdemanding or underdemanding but also stimulating, relevant to learning and meaningful, thus positively or negatively stressful) and resources (potentially beneficial working conditions, experience, or behavior, e.g., social support, scope for action). Fluctuations within surgical specialties and a high dropout rate during residency training are well known and the causes include high psychological stress. In the case of persistent and at the same time insufficient compensation of work stress caused by a lack of or insufficient resources, these can be associated with mental illnesses. Nonetheless, many physicians spend their entire lives working in hospital or private surgical settings and remain healthy, a strong sense of resilience to mental illness may be fundamental to this. Resilience can be present as a personal characteristic or it can be learnt through a process or adapted through positive or negative influences, thus strengthening the personal characteristics. Overall, data on surgeon resilience or interventional studies in resilience research in the surgical setting are limited and provide another research gap. Resilience training (directed at a sense of coherence, social support, strengthening knowledge of coping skills, positive emotions, optimism, hope, self-efficacy expectations, control beliefs or robustness), also clearly indicated in the "robust" medical specialty of surgery, is always individual and should not be generalized. If the surgeon cannot retrieve sufficient resources due to the stressful situation, stress management with its methods is helpful to reduce the psychological stress and to be able to maintain the performance and health of this person. CONCLUSION: The consolidation of resilience as a notable aspect of employee management. In collegial interactions, resilience must be based on workplace-based approaches to strengthen coping mechanisms in the face of work stress. Workplace-related stress should also be perceived, addressed and counteracted within the organization, certainly also as an elementary management task.

Complete rectal prolapse presenting with colorectal cancer.

Objectives: Rectal prolapse is defined as prolapse of all layers of rectal wallout of the anal sphincter. The aim was to (i) describe the extremely rare combination of a rectal prolapse with colon cancer in an older female patient, (ii) comment on management-specific aspects and (iii) derive some generalizing recommendations by means of a scientific case report and based on the case-specific experiences related to the clinical management and current references from the medical literature. Case presentation: A 69-year old female patient with cancer of the sigmoid colon at a manifest rectal prolapse was diagnosed. Literature search (using the data bank of "PubMed") resulted in only six patients (the majority of them were females) with the coincidence of rectal prolapse and rectal or colon cancer have been reported so far. Conclusions: A patient with a manifest rectal prolapse needs always to undergo colonoscopy and - in case of an ulcer - histological investigation of representative biopsies.

Does intestinal anastomosis in resection of colon cancer have a significant impact onto early postoperative outcome and long-term survival?

Objectives: To investigate the influence of anastomosis on the early postoperative and long-term oncological outcomes of patients with primary colon carcinoma (CA). Methods: All consecutive patients with the histologically diagnosed primary colon CA (design, prospective multicenter observational study) were registered with regard to patient-, diagnostic-, tumor (Tu) finding-, and treatment-related aspects using a computer-based registry with 60 items to characterize early postoperative and long-term oncological outcome. Results: Basic data: From 2010 to 2016, data from a total of 14,466 patients were documented (mean age, 72.8 [range, 22-96] years; sex ratio, m:f=7,696:6,770). - 717/14,466 patients (4.96 %) were included in a matched-pair analysis. The majority of these patients underwent elective surgery (n=12,620 patients; 87.2 %) regardless of whether a bowel anastomosis or an ostomy was created. In emergency surgery, a bowel anastomosis was possible in a large proportion (n=1,332 patients [72.1 %]). In contrast, in 514 patients (27.9 %) who underwent emergency surgery, an ostomy was created. Interestingly, ostomy had to be created even less frequently in patients who had undergone planned surgery (n=366 [2.5 %]). - Early postoperative outcome: Cases of postoperative mortality were mainly due to general complications. Especially among the patients treated in an emergency situation without intestinal anastomosis, a high proportion died of their pre-existing condition (17.0 %). Patients who underwent ostomy creation or emergency surgery had a worse risk profile (incl. arterial hypertension, diabetes mellitus, and secondary cardiac or renal diseases) which led to the decision to operate without anastomosis. Furthermore, data show no matter which technique had been used, patients that had undergone surgical intervention without anastomosis were more likely to develop complications. - Long-term oncosurgical outcome: The most important factors influencing long-term survival were age, resection status, and tumor stage (according to TNM and UICC). The more advanced the tumor growth, the lower the long-term survival. Patients categorized with the same tumor stage, age, and risk factors had a better chance of survival, if they underwent elective surgical intervention and with intestinal anastomosis. Interestingly, the multivariable analysis showed that older patients and such with distant metastasis benefit from a discontinuity resection. Conclusions: The association of intraoperative and postoperative complications with increased postoperative mortality, as well as preexisting risk factors and perioperative complications is in line with findings of current studies. Furthermore, current studies also agree that older patients and such with reduced general condition benefit from discontinuity resection.

Prehabilitation in elective surgical interventions - what must the general and abdominal surgeon know.

Objectives: For years, many efforts have been invested to prepare patients, in particular, those with reduced physical and psychic status, much better to provide and finally achieve better outocme if there is time available to provide several beneficial measures. Methods: Therefore, the objective was to illustrate the concept and various single elements of a complex prehabilitation concept based on (i) selective references from the medical literature and (ii) own clinical experiences from clinical practice in general and abdominal surgery. Results: Prehabiliation can be considered the solution of the efforts to improve preoperative status for patients in a disadvantageous status for almost all types of surgery and all other operative and/or interventional procedures. It is the targeted process to improve individual functionality and organ function before a planned (elective) surgical intervention; P. comprises basically nutritional, physical and psychological measures; P. focusses especially onto the elderly, frail and malnourished patients before a planned surgical intervention; the overall aim is to significantly improve final outcome characterized by shorter length of stay, lower complication rate and mortality as well as cost efficiency; P. is especially important in cancer surgery, in which the beneficial effects can be particularly implemented; P. programs and/or "Standard Operating Protocols" (SOP) may help to establish and materialize its single aspects and enhanced recovery after surgery (ERAS). There is still further potential to reliably establish and to utilize the options of prehabilitation measures as listed above. Conclusions: Prehabiliation is an indispensable aspect in today's preparation for elective surgery, which needs to become obligatory part of the preparation measures to planned surgical interventions, which can further contribute to a better final outcome and ERAS as well as, in addtion, needs to be further developed and accomplished.

Status of inpatient pain therapy using the example of a general and abdominal surgery normal ward - a prospective questionnaire study to review a pain therapy algorithm ("real-world data").

Objectives: The mean pain intensity for inpatient consultations, for example in cancer patients, is known. However, the proportion of necessary consultations in the total volume of patients of a ward or a hospital, the general pain intensity in a surgical ward and the relationship between pain medication, length of stay and therapeutic success are unknown. The aim of the study was to examine surgical patients in a single normal ward subclassified into various groups (-/+ surgery, ICU stay, cancer, consultation for pain therapy etc.) during half a year with regard to their pain. For this purpose, the pain score (NAS) was recorded daily for each patient during the entire hospital stay and the change was assessed over the clinical course. Methods: In 2017, all consecutive new admissions to a normal ward of general surgery at a university hospital ("tertiary center") were monitored over half a year according to a standardized procedure. Pain severity (measured by the "Numeric rating scale" [NRS] respectively "Visual analogue scale" [VAS]) from admission to discharge was recorded, as well as the length of stay and the administered medication. Patient groups were sub-classified as surgery, intensive care unit, cancer and pain consultation. An algorithm in two parts (part 1, antipyretics and piritramide; part 2, WHO-scheme and psychotropic drugs), which was defined years before between surgeons and pain therapists, was pursued and consequently used as a basis for the evaluation of the therapeutic success. Results: 269 patients were included in the study. The mean pain intensity of all patients at admission was VAS 2.2. Most of the groups (non-cancer, intensive care unit [ICU], non-ICU, surgical intervention (=Operation [OP]), non-OP, pain intensity greater than VAS 3) were significantly reduced in pain at discharge. An exception in this context was patients with cancer-associated pain and, thus, initiated pain consultation. Conclusions: Since three quarters of the consultation patients also reported cancer pain, it might be possible that the lack of treatment success in both the consultation and cancer groups is associated with cancer in these patients. However, it can be shown that the successfully treated groups (without ICU-based course) had a mean length of stay from 4.2 ± 3.9 up to 8.4 ± 8.1 days (d), while the two unsuccessfully treated groups experienced a longer stay (mean"cancer", 11.1 ± 9.4 d; mean"consulation", 14.2 ± 10.3 d). Twenty-one consultation patients, in whom it had been intended to improve pain intensity, could not be successfully treated despite adapted therapy - this can be considered a consequence of the low number of patients. Since the consultation patients were the only patient group treated with part 2 of the algorithm, it can be concluded that part 1 of the algorithm is sufficient for a mean length of stay up to 9 days. For all patients above this time point, a pain consultation with adaption of medical treatment should be considered.

Paradox inflammatory reaction such as appendicitis epiploica and diverticulitis of the sigmoid colon under ongoing immunosuppression after previous liver transplantation (LTx).

Objective: Inflammatory reactions caused by immunosuppression appear a particular interesting disease due to its very specific and partly unclear etiopathogenesis.Based on clinical case-specific management experiences and selective references from the literature, the rare case of an acute intraabdominal inflammation as unusual complication or side effect (at the gastrointestinal [GI] tract) of the ongoing immunosuppressive medication using Mycophenolate mofetil and Tacrolimus after previous liver transplantation is to be illustrated. Case presentation: Medical history (hx): 1) Current: A 68-years old male patient underwent abdominal CT scan because of pain in the left lower abdomen with the suspicious diagnosis of diverticulitis leading to initiation of antibiotic therapy 24 h prior to the transferral to the own hospital for adequate liver transplantation (LTx) follow-up investigation. 2) Medication contained Sitagliptin 1 × 100 mg, Omeprazol 1 × 40 mg, Mesalazin 500 mg 3 × 2, Movicol 1 (on demand), Mycophenolate mofetil 2 × 500 mg, Tacrolimus 2 × 1 mg and Hydrochlorothiazid 1 × 2.5 mg. 3) Additional diagnoses included arterial hypertension, diabetes mellitus and urinary bladder diverticle. 4) Previous surgical intervention profile comprises resection of liver segments IV/V due to HCC (2011), orthotopic liver transplantation because of HCC caused by alcohol-induced liver cirrhosis (2013) and an intervertebral disc operation (2018). Physical examination of the abdomen revealed marked tenderness in the lower left quadrant. The abdominal wall was soft and there were no defensive tension and no peritonism. The patient was in good general condition and nutritional status. He was cardiopulmonarily stable and oriented to all qualities. Diagnostic measures showed a CRP of 38.0 (normal range, < 5) mg/L and a white blood cell count within normal range. Leading diagnoses were found using abdominal CT scan, which demonstrated an extended diverticulosis and an appendicitis epiploica within the immediate subperitoneal region of the left lower abdomen with an oval fat isodense structure in the region of the sigmoid colon with surrounding inflammatory imbibition and pronounced intestinal wall. Suspicious diagnosis was the 1st episode of an uncomplicated diverticulitis of the sigmoid colon associated with an appendicitis epiploica. Therapeutic approach was given by conservative therapy with infusion therapy, analgesia as well as inital "n. p. o." and following initiation of oral nutrition. In addition, calculated antibiotic therapy with Cefuroxime and Clont was initiated. Clinical course was uneventful, with discharge on the eighth day of hospital stay with no pathological findings and substantial improvement in clinical and laboratory findings. Further advice consisted of clinical and laboratory follow-up control investigations by the family practitioner and nutritional counselling. In addition, a colonoscopy should be performed within four months. Conclusions: The described case i) is either one of the many side effects of the immunosuppressive medication Mycophenolate mofetil and Tacrolimus listed as "colonic inflammation" and "gastrointestinal inflammation", respectively, or ii) can be considered an inflammatory response of a susceptible (gastro-)intestinal mucosa or the whole intestinal wall to microbes or microbial particles or agents caused by transplantation-associated immunosuppressive medication.

Laparoscopic cholecystectomy for symptomatic cholecystolithiasis (CCL) in "Kasabach-Merritt syndrome" (KMS) (Kaposi-tumor like hemangioendothelioma with case-specific perioperative management).

Objectives: The Kasabach-Merritt syndrome (KMS) is characterized by the occurrence of hemangioendothelioma (giant hemangioma with thrombosis leading to thrombocytopenia), which can be associated with disseminated intravasal coagulation. Specific aim: Based on (i) selective references from the current scientific literature and derived recommendations as well as (ii) own experiences obtained in the diagnostic and perioperative management of a representative case from daily practice in abdominal surgery, the specific case undergoing elective cholecystectomy (CCE) in KMS is to be described by means of scientific case report. Case presentation: (Patient-, finding- and treatment-specific characteristics): - Medical history: 72-years old female patient with a known KMS of the left arm and upper thorax, recurrent thrombophlebitis of the left arm and thoracic veins, previous upper GI bleeding (Mallory-Weiss syndrome in 2006, chronic anemia in lack of vitamin B12, type-A gastritis, former bleeding complications after teeth extraction/open appendectomy 1962/Caesarean section 1968 with need of transfusion [60 red blood cell packages]), intraabdominal adhesions, hypothyreosis, initial liver cirrhosis. - Symptomatology: Characteristic for cholecystolithiasis (CCL). - Diagnostic: Abdominal ultrasound shows CCL, fibroscan does not confirm suspicious cirrhosis. Laboratory parameters showed: Activation of intravasal coagulation with elevated prothrombin fragments, D-dimers and reduced antiplasmin concentration. Accelerated fibrinolysis capacity; currently, no secondary thrombocytopenia or factor-13 decrease. In addition, fibrinogen concentration within normal range, no hint onto the manifestation of an aquired von-Willebrand's syndrome. - Diagnosis: Chronic fibrosing cholecystitis in CCL after former acute cholecystitis (3 months ago) with indication for surgical intervention. - Therapy: Laparoscopic CCE including careful exploration of upper abdominal cavity for KMS manifestation (with no revision of bile duct) and peritoneal adhesiolysis (histological finding, chronic fibrosing cholecystitis with thickening of the wall of the gall bladder but no hint of malignancy) under perioperative prophylaxis with antibiotics and temporary cessation of platelet medication for 7 d preoperatively, "bridging" with low molecular weight heparin (Clexane, 1 × 40 mg s.c.; Sanofi-Aventis, Frankfurt/Main, Germany); 1 h preoperatively, 15-20 mg/kg body weight Cyclocapron i.v. (once again 6-8 h postoperatively; thereafter, 500 mg of Cyclocapron 4×/d until the 3rd postoperative day). - Intraoperatively: Congestion of veins but not at the immediate surgical field (gall bladder, hepatic bed of the gall bladder, Calot's triangle). - Outcome: Uneventful, in particular, no (bleeding) complications. Conclusions: If surgical approach is indicated, the intervention should be thoroughly planned (in particular, under elective circumstances) with regard to hemangioma site and extension as well as distance to the surgical field and possible surgical alternative options (surgical access site, open/laparoscopic approach etc.) to prevent - at the best possible rate - bleeding complications intra-/postoperatively and, thus, to provide adequate patient safety.

Multivisceral resection of advanced colon and rectal cancer: a prospective multicenter observational study with propensity score analysis of the morbidity, mortality, and survival.

Objectives: In the surgical treatment of colorectal carcinoma (CRC), 1 in 10 patients has a peritumorous adhesion or tumor infiltration in the adjacent tissue or organs. Accordingly, multivisceral resection (MVR) must be performed in these patients. This prospective multicenter observational study aimed to analyze the possible differences between non-multivisceral resection (nMVR) and MVR in terms of early postoperative and long-term oncological treatment outcomes. We also aimed to determine the factors influencing overall survival. Methods: The data of 25,321 patients from 364 hospitals who had undergone surgery for CRC (the Union for International Cancer Control stages I-III) during a defined period were evaluated. MVR was defined as (partial) resection of the tumor-bearing organ along with resection of the adherent and adjacent organs or tissues. In addition to the patients' personal, diagnosis (tumor findings), and therapy data, demographic data were also recorded and the early postoperative outcome was determined. Furthermore, the long-term survival of each patient was investigated, and a "matched-pair" analysis was performed. Results: From 2008 to 2015, the MVR rates were 9.9 % (n=1,551) for colon cancer (colon CA) and 10.6 % (n=1,027) for rectal cancer (rectal CA). CRC was more common in men (colon CA: 53.4 %; rectal CA: 62.0 %) than in women; all MVR groups had high proportions of women (53.6 % vs. 55.2 %; pairs of values in previously mentioned order). Resection of another organ frequently occurred (75.6 % vs. 63.7 %). The MVR group had a high prevalence of intraoperative (5.8 %; 12.1 %) and postoperative surgical complications (30.8 % vs. 36.4 %; each p<0.001). Wound infections (colon CA: 7.1 %) and anastomotic insufficiencies (rectal CA: 8.3 %) frequently occurred after MVR. The morbidity rates of the MVR groups were also determined (43.7 % vs. 47.2 %). The hospital mortality rates were 4.9 % in the colon CA-related MVR group and 3.8 % in the rectal CA-related MVR group and were significantly increased compared with those of the nMVR group (both p<0.001). Results of the matched-pair analysis showed that the morbidity rates in both MVR groups (colon CA: 42.9 % vs. 34.3 %; rectal CA: 46.3 % vs. 37.2 %; each p<0.001) were significantly increased. The hospital lethality rate tended to increase in the colon CA-related MVR group (4.8 % vs. 3.7 %; p=0.084), while it significantly increased in the rectal CA-related MVR group (3.4 % vs. 3.0 %; p=0.005). Moreover, the 5-year (yr) overall survival rates were 53.9 % (nMVR: 69.5 %; p<0.001) in the colon CA group and 56.8 % (nMVR: 69.4 %; p<0.001) in the rectal CA group. Comparison of individual T stages (MVR vs. nMVR) showed no significant differences in the survival outcomes (p<0.05); however, according to the matched-pair analysis, a significant difference was observed in the survival outcomes of those with pT4 colon CA (40.6 % vs. 50.2 %; p=0.017). By contrast, the local recurrence rates after MVR were not significantly different (7.0 % vs. 5.8 %; both p>0.05). The risk factors common to both tumor types were advanced age (>79 yr), pT stage, sex, and morbidity (each hazard ratio: >1; p<0.05). Conclusions: MVR allows curation by R0 resection with adequate long-term survival. For colon or rectal CA, MVR tended to be associated with reduced 5-year overall survival rates (significant only for pT4 colon CA based on the MPA results), as well as, with a significant increase in morbidity rates in both tumor entities. In the overall data, MVR was associated with significant increases in hospital lethality rates, as indicated by the matched-pair analysis (significant only for rectal CA).

Interdisciplinary aspects of abdominal and plastic surgery - what does the (abdominal) surgeon need to know?

Introduction: The aim was to reflect the established interdisciplinary aspects of general/abdominal and plastic surgery by means of a narrative review. Methods: (i) With specific references out of the medical literature and (ii) own clinical and perioperative as well as operating technical and tactical management experiences obtained in surgical daily practice, we present a choice of options for interdisciplinary cooperation that could be food of thought for other surgeons. Content: - Decubital ulcers require pressure relieve, debridement and plastic surgery coverage, e.g., by a rotation flap plasty, V-Y flap or "tensor-fascia-lata" (TFL) flap depending on localization (sacral/gluteal defects, ischiadic tuber). - Coverage of soft tissue defects, e.g., after lymph node dissection, tumor lesions or disturbance of wound healing can be managed with fasciocutaneous or muscle flaps. - Bariatric surgery: Surgical interventions such as butt lift, tummy tuck should be explained and demonstrated in advance and performed commonly after reduction of the body weight. - Abdominoperineal rectum extirpation (APE): Holm's procedure with greater circumferential extent of resection at the mesorectum and the insertion site of the levator muscle at the anal sphicter muscle resulting in a substantial defect is covered by myocutaneous flap plasty. - Hernia surgery: Complicated/recurrent hernias or abdominal wall defect can be covered by flap plasty to achieve functional reconstruction, e.g., using innervated muscle. Thus, abdominal wall can respond better onto changes of pressure and tension. - Necrotising fasciitis: Even in case of suspicious fasciitis, an immediate radical debridement must be performed, followed by intensive care with calculated antibiotic treatment; after appropriate stabilization tissue defects can be covered by mesh graft of flap plasty. - Soft tissue tumor lesions cannot be resected with primary closure to achieve appropriate as intended R0 resection status by means of local radical resection all the time - plastic surgery expertise has to be included into interdisciplinary tumor concepts. - Liposuction/-filling: Liposuction can be used with aesthetic intention after bariatric surgery or for lipedema. Lipofilling is possible for reconstruction and for aesthetic purpose. - Reconstruction of lymphatic vessels: Lymphedema after tumor operations interrupting or blocking lymphatic drainage can be treated with microsurgical reconstructions (such as lympho-venous anastomoses, lympho-lymphatic anastomoses or free microvascular lymph node transfer). - Microsurgery: It is substantial part of modern reconstructive plastic surgery, i.e., surgery of peripheral nerves belongs to this field. For visceral surgery, it can become important for reconstruction of the recurrent laryngeal nerve. - Sternum osteomyelitis: Radical debridement (eventually, complete sternal resection) with conditioning of the wound by vacuum-assisted closure followed by plastic surgery coverage can prevent chronification, threatening mediastinitis, persisting infectious risk, long-term suffering or limited quality of life. Summary: The presented selection of single topics can only be an excerpt of all the options for surgical cooperation in daily clinical and surgical practice. Outlook: An interdisciplinary approach of abdominal and plastic surgery is characterized by a highly developed cooperation in common surgical interventions including various techniques and tactics highlighting the specifics of the two fields.

Fatal heat stroke based on foudroyant irreversible multiple organ dysfunction in German summer.

Objectives: Heat stroke is a serious condition that might lead from moderate organ impairment to multiple organ dysfunction syndrome. Appropriate diagnosis-finding, fast initiation of cooling and intensive care are key measures of the initial treatment. Scientific case report based on i) clinical experiences obtained in the clinical management of a particularly rare case and ii) selected references from the medical scientific literature. Case presentation: We present a case of a young and healthy construction worker who suffered from an exertional heat stroke with a body core temperature exceeding 42 °C by previous several hour work at 35 °C ambient temperature. Heat stroke was associated with foudroyant, not reversible multiple organ dysfunction syndrome, in particular, early disturbed coagulation, microcirculatory, liver and respiratory failure, and subsequent fatal outcome despite immediate diagnosis-finding, rapid external cooling and expanded intensive care management. Conclusions: Basic knowledge on an adequate diagnosis(-finding in time) and treatment of heat stroke is important for (almost each) physician in the summertime as well as is essential for the initiation of an appropriate management. Associated high morbidity and mortality rates indicate the need for implementation of standard operation protocols.

[Outpatient and "Admission-Substituting" Interventions in Vascular Surgery - What is Feasible and Where are the Limits? Previous and New Legal Requirements and their Implementation in Practice]. / Ambulante und stationsersetzende Eingriffe in der Gefäßchirurgie ­ was ist machbar und wo liegen die Grenzen? Bisherige und neue gesetzliche Vorgaben sowie deren Umsetzung in der Praxis.

INTRODUCTION: In vascular surgery too, more services and procedures will have to be shifted from the previous inpatient to the outpatient sector in the future. Therefore, the previous and new legal requirements as well as their implementation in vascular surgery will be explained and evaluated. MATERIAL AND METHODS: Professional policy analysis from a perspective of medical vascular surgery. RESULTS: The AOP catalog from 01.01.2023 was extended by 208 additional OPS codes. The inpatient performance of services which, according to the AOP contract, must be regularly performed on an outpatient basis, are now to be justified on the basis of context factors.A special sector-equivalent remuneration, which is independent of whether the remunerated service is performed on an outpatient or inpatient basis, is a prerequisite for a cost-covering expansion of outpatient operations and inpatient-replacing services. The rehabilitation of primary varicosis under outpatient conditions is undoubtedly the standard. The majority of AV shunt installations are performed as inpatient procedures. No new OPS codes were added to the 2023 AOP catalog for varicose vein, shunt and endovascular surgery. DISCUSSION: The shift of inpatient services to the outpatient sector can be a feasible path, based on the experience of other European countries. However, the structures, economic conditions and incentives should first be created to successfully promote transfer to outpatients. Integrated care offers the possibility for the health insurance funds to conclude contracts with the service providers named in § 140a of the Social Code, paragraph 3, for special care. The use of telemedicine in the sense of tele-premedication or tele-monitoring can be a way to expand outpatient surgery, especially in rural regions. In order to enable therapy concepts from one expert in vascular medicine, the outpatient service billing of interventional procedures must also be demanded by vascular surgeons and specialists. CONCLUSION: The potential to transform inpatient services into the outpatient setting of service provision is realisable in vascular surgery in the core areas of varicose vein surgery, shunt surgery and peripheral interventional procedures under specific conditions.

[COVID-19 as an insurance case of the statutory accident insurance: occupational disease or occupational accident : Relevant knowledge for the (general and abdominal) surgeon]. / COVID-19 als Versicherungsfall der gesetzlichen Unfallversicherung: Berufskrankheit oder Arbeitsunfall : Relevantes Wissen für den (Allgemein­/Viszeral­)Chirurgen.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic resulted in many infections with the virus and sickness due to coronavirus disease 2019 (COVID-19). Therefore, there was a dramatic increase in the number of reported and recognized occupational diseases (Berufskrankheit, BK) and occupational accidents (Arbeitsunfall, AU) at the German Social Accident Insurance Institutions (BG) and accident insurance funds (Unfallkassen).The publication aims to show the differences between BK and AU and to review the current data on occupational diseases. It deals with the definitions of BK and AU, the differences in the conditions for recognition as BK or AU. Furthermore, the claims for benefits are presented. Finally, statistical key figures of the BK according to No. 3101 and the AU are presented.Results (key points)- According to § 7 SGB VII, AU and BK are insured events of the statutory accident insurance.- In surgery, like specifically in the rest of the healthcare system, the relevance of the SARS-CoV­2 infection with post-COVID in personnel for occupational medical prevention and as a case to be recognized by the statutory accident insurance (BK or AU) becomes clear.- Relevant for the recognition are the duration and the intensity of the contact (local proximity) and the SARS-CoV­2 occupational health and safety rule of 20 August 2020 essentially recognizes a contact duration of at least 15 min at a spatial distance of less than 1.5-2 m (further aspects: more intensive shorter contacts, number of verifiably infected persons in the closer activity environment or the usual personal contacts, spatial situation, work route, special constellations).- No case numbers can be elicited for the detailed presentation of the surgery setting.- There are still immense problems and challenges in the assessment of COVID-19 consequences or post-COVID as occupational disease, as numerous uncertainty factors, such as insufficiently secured knowledge about the further long-term course over the years or the widely varied symptom spectrum complicates the medical assessment of the consequences of this disease.Conclusion: the SARS-CoV­2 pandemic is a special challenge for surgery with intensive patient contact and for the entire healthcare system. This caused long-lasting changes and the adequate health care as well as insurance law processing of the (case-specific) consequences might still require considerable efforts and resources.

[The abdominal brain: neuroanatomic perspectives for the abdominal surgeon]. / Das Bauchgehirn: neuroanatomische Perspektiven für den Viszeralchirurgen.

The "abdominal brain" does not only consist of a separate enteric nervous system but also of bidirectional connections to the autonomous nerve system with parasympathicus und sympathicus as well as brain and spinal cord. Novel studies have shown that these connections can quickly transfer information on the ingested nutrients to the brain to conduct the feeling of hunger and more complex behaviour, such as "reward-related learning". However, even emotional experience, in particular, stress, has a strong impact onto the gastrointestinal system. The immune system, motility and barrier function of the gastrointestinal tract are modulated by the intestinal microbiota. Local bacteria may directly influence neuronal communication by released metabolic products and neuropeptides as well as may control inflammatory factors. Intensive research over the last 10 years was able to provide evidence that intestinal microbiota may affect emotional and cognitive aspects of our behaviour and, thus, it might be in the focus of numerous neuropsychiatric diseases, such as depressions and anxiety disorders.The presented review is to provide a short summary of the I): anatomic basics of the so-called gut-brain axis and II): modi of the bidirectional regulation. Through indirect connections to the limbic system, gut-brain axis can substantially influence stress and anxiety but also the pain processing. In addition, the role of microbiota is outlined and future paths are shown, e.g., how the (microbiota-)gut-brain axis may alter emotional experience, pain processing and intestinal function. Such associations are relevant for further development of visceral medicine, and, thus, also for the abdominal surgeon to derive future treatment concepts with interdisciplinary orientation.
