Abstract
Lymph node dissection is a crucial element of oncologic rectal surgery. Many guidelines regard the removal of at least 12 lymph nodes as the quality criterion in rectal cancer. However, this recommendation remains controversial. This study examines the factors influencing the lymph node yield and the validity of the 12-lymph node limit. Patients with rectal cancer who underwent low anterior resection or abdominoperineal amputation between 2000 and 2010 were analyzed. In total, 20,966 patients from 381 hospitals were included. Less than 12 lymph nodes were found in 20.53% of men and 19.31% of women (p = 0.03). The number of lymph nodes yielded increased significantly from 2000, 2005 and 2010 within the quality assurance program for all procedures. The univariate analysis indicated a significant (p < 0.001) correlation between lymph node yield and gender, age, pre-therapeutic T-stage, risk factors and neoadjuvant therapy. The multivariate analyses found T3 stage, female sex, the presence of at least one risk factor and neoadjuvant therapy to have a significant influence on yield. The probability of finding a positive lymph node was proportional to the number of examined nodes with no plateau. There is a proportional relationship between the number of examined lymph nodes and the probability of finding an infiltrated node. Optimal surgical technique and pathological evaluation of the specimen cannot be replaced by a numeric cut-off value.

Abstract
BACKGROUND It is still a matter of debate what the best management of peritonitis is following eliminating the source of infection. This particularly concerns the amplitude of local and systemic inflammatory response as well as bacterial clearence at the infectious site. AIM To investigate the effects of vacuum-assisted closure (VAC) vs. relaparotomy on demand (ROD) onto the i) severity and course of disease, ii) surgical outcome, iii) intraperitoneal bacterial load as well as iv) local and systemic inflammatory and immune response in postoperative secondary peritonitis. METHODS Over a defined time period, all consecutive patients of the reporting surgical department with a secondary peritonitis (assessed by Mannheim's Peritonitis Index [MPI] and APPACHE II score) were enrolled in this systematic unicenter clinical prospective observational pilot study reflecting daily surgical practice and as a contribution to internal quality assurance. Patients were subclassified into VAC or ROD group according to surgeon's individual decision at the time point of primary surgical intervention with the intent to sanitize the source of infection. Early postoperative result was assessed by 30-d and in-hospital mortality. Bacterial load was characterized by microbiological culture of intraperitoneal fluid collection obtained on postoperative days (POD) 0 (primary surgical intervention), 1, 4, 7, 10, 13 and following description of the microbial spectrum including semiquantitative assessment of bacterial load. Local and systemic inflammatory and immune response was determined by ELISA-based analysis of CrP, PCT and the representative cytokines such as TNF-α, IL-1β, IL-6, IL-8, and IL-10 of serum and peritoneal fluid samples. RESULTS Over a 26-months investigation period, 18 patients (sex ratio, male:female=9:9) were eligible for study criteria: n=8 were enrolled in the VAC (m:f=4:4) and n=10 in the ROD group (m:f=5:5). With regard to early postoperative results represented by mortality, there is no significant difference between both patients groups. Despite the relatively low number of cases enrolled in this study, a trend for more severe findings associated with the VAC group could be detected based on MPI score. There was also a trend of higher APACHE II scores in the VAC group from the 7th POD on and, in addition, patients of this group had a longer hospital stay. For patients with persisting infection, there were no relevant differences comparing VAC therapy and ROD. Cytokines released, in particular, at the beginning of the inflammation cascade with proinflammatory characteristics, showed higher values within the peritoneal fluid whereas CrP and PCT were found to be higher within the serum samples. Summary & Conclusion: Comparing data of various local and systemic inflammatory and immune parameters, there were only a few correlations. This may indicate a compartimentation of the inflammatory process within the abdominal cavity. Based on the observed inter-individual variation of this pilot study data, the clinically applicable benefit appears questionable. In this context, a reliable effect of VAC therapy onto reduction of bacterial burden within the abdominal cavity could not clearly be detected.

Abstract
SummarySpontaneous intraabdominal hemorrhage is a very rare event even in patients with bleeding disorders like hemophilia. Nevertheless this rare case must be considered in patients with coagulopathies presenting with abdominal pain. Prompt radiologic imaging and surgical consultation are of highest priority. Here we report on a 20-year-old patient with moderate hemophilia A, who underwent emergency laparotomy for a spontaneous idiopathic bleeding of the omentum majus. There are few cases in the literature on this sort of event in patients with hemophilia, who mostly suffer from spontaneous joint bleedings. These patients require an intensive, interdisciplinary perioperative care, involving haematologists, surgeons, radiologists and anesthesists. Finally we discuss, whether an optimized, individually adapted treatment with coagulation factors might possibly have prevented this bleeding event in this patient.

Abstract
Background An anastomotic leak (AL) after colorectal surgery is one major reason for postoperative morbidity and mortality. There is growing evidence that AL affects short and long term outcome. This prospective German multicentre study aims to identify risk factors for AL and quantify effects on short and long term course after rectal cancer surgery. Methods From 1 January 2000 to 31 December 2010 381 hospitals attributed patients to the prospective multicentre study Quality Assurance in Colorectal Cancer managed by the Otto-von-Guericke-University Magdeburg (Germany). Included were 17 867 patients with histopathologically confirmed rectal carcinoma and primary anastomosis. Risk factor analysis included 13 items of demographic patient data, surgical course, hospital volume und tumour stage. Results In 2 134 (11.9%) patients an AL was diagnosed. Overall hospital mortality was 2.1% (with AL 7.5%, without AL 1.4%; p < 0.0001). In multivariate analysis male gender, ASA-classification ≥III, smoking history, alcohol history, intraoperative blood transfusion, no protective ileostomy, UICC-stage and height of tumour were independent risk factors. Overall survival (OS) was significantly shorter for patients with AL (UICC I-III; UICC I, II or III - each p < 0.0001). Disease free survival (DFS) was significantly shorter for patients with AL in UICC I-III; UICC II or UICC III (each p < 0.001). Rate of local relapse was not significantly affected by occurrence of AL. Conclusion In this study patients with AL had a significantly worse OS. This was mainly due to an increased in hospital mortality. DFS was also negatively affected by AL whereas local relapse was not. This emphasizes the importance of successful treatment of AL related problems during the initial hospital stay.

Abstract
Unusual locations of the appendix vermiformis can result in delay in appropriate diagnosis and treatment of appendicitis. So an inflamed appendix in a sub-hepatic caecum caused by caecal maldescent for example can mimic cholecystitis, the pain being localized in the right upper quadrant. Here, we present a case of perforated sub-hepatic appendicitis with peritonitis, requiring open ileocaecal resection. Review of the existing literature has demonstrated that this pathology is uncommon, yet not so rare as one might presume. In conclusion, surgeons should be aware of this possibility in the diagnostic and therapeutic management of acute abdomen.

Abstract
PURPOSE In hepatic resections, there has been a high quality demand. The aim of this systematic clinical, prospective, unblinded unicenter observational study with two arms in an unselected patient cohort was to investigate whether hemostat device can significantly improve outcome in resective liver surgery, in particular, in high risk patients. METHODS All consecutive patients (mean age, 60.5 [range, 17 - 96] years) who underwent hepatic resection (ntotal = 770) were prospectively documented in a computer-based registry at a university hospital (tertiary center) over a time period of 10 years and retrospectively evaluated specifically with regard to the use (-/+; in daily practice and intraoperative decision-making) of hemostat device (Tissucol(®), n = 59/Tachocomb(®), n = 202/combination, n = 55) indicated (among others) by drainage volume, inflammatory parameters and rate of specific complications (nvalidated = 541 [100 %]). RESULTS Most frequently, (a-)/typical segmental resections were used: n = 192/90 (3-segment resection, only n = 38). 1) For the assignment of patients to the two different groups (-/+ hemostat device), weight loss and type of resection were found as significant factors (trend: ASA, cirrhosis), for the amount of drainage volume, ASA, sex, Karnofsky Performance Scale and also type of resections using independent distributed statistical tests (such as χ(2), U test [Mann/Whitney]; H test [Kruskal-Willis]; correlation coefficient by Spearman) - no impact: smoking, diabetes, BMI, ethanol. 2) Not taking into account these parameters, the use of hemostat device was characterized by an increased drainage volume (negative control < Tissucol = Tachocomb < combination). 3) Using multifactorial analysis of variance, it was found even under correction by the factors with significant impact elucidated in the single test that the application of hemostat device onto the hepatic resection area resulted unexpectedly rather in an increase than a decrease of the drainage volume but 4) under accompanying more pronounced increase of the white blood cell count (leucocytosis). 5) General and specific complications such as postoperative bleeding, biliary fistula and subhepatic abscess were not further lowered in a significant manner using hemostat device. CONCLUSION Adequate surgery in the operative management of hepatic resection area cannot further be improved or optimized using hemostat device. In this context, drainage volume may not be considered a sufficient rather an orienting parameter. However, there is an inflammatory response detectable most likely indicated by a(n un-)specific effusion and increase of white blood cell count, which can be interpreted as a) being characteristic for the problematic group of patients, in whom hemostat device was decided to be useful and was finally used in daily prectice, or b) reactive inflammation to foreign material.

Abstract
BACKGROUND The majority of infections treated by surgeons are nosocomial infections (NI). The frequency of these infections in relation to the organ operated on as well as the organisms involved are not well defined. Detailed knowledge of these issues is essential for optimal care of surgical patients. This study aimed to determine infection rates and the responsible pathogens after major elective surgery of the pancreas, liver, stomach, and esophagus. METHODS Between January 1, 2005 and August 31, 2007, the records of all patients of the Department of General, Abdominal and Vascular Surgery, University Hospital Magdeburg (Germany) with elective resection of the pancreas, liver, stomach, and esophagus were evaluated retrospectively. Study parameters were: Patient number, age, gender, body mass index (BMI), American Society of Anesthesiologists (ASA) classification, indication for resection, operation duration, length of stay (LOS) in the intensive care unit (ICU) and in hospital, mortality, organ-related rate and kind of NI, and microbiologic spectrum. Nosocomial infections were defined as: Surgical site infection (U.S. Centers for Disease Control and Prevention [CDC] 1 or 2) and intra-abdominal infection (CDC 3), urinary tract infection, clinical sepsis, blood stream and catheter-related infection, respiratory tract infection, and pneumonia. RESULTS A total of 358 patients were included: 150 (42%) with pancreas resection, 91 (25%) with liver resection, 105 (29%) with gastric resection, and 12 (3%) with esophagus resection. Median LOS in the ICU for all groups was 48.8 h (interquartile range [IQR] 24.9-91.8 h), median LOS in hospital was 16 d (IQR 13-23 d), and in-hospital mortality was 4.5%. Patients with NI had significantly greater in-hospital death and prolonged stay in hospital and ICU (p<0.001). In 120 (33.5%) patients, one or more NI occurred (range, 83% in esophagus patients to 21% in liver patients). Intra-abdominal (16.5%) and surgical site infections (12.3%) were most frequent; 80.8% of the NI were culture-positive. The most frequent clinically relevant isolates were Escherichia coli (12.4%), coagulase-negative staphylococci (CoNS) (12.2%), and Enterococcus faecium (9.7%). The highest resistance rates were found for Staphylococcus aureus (methicillin-resistant S. aureus [MRSA] 29.4%) and Pseudomonas aeruginosa (23.5%). CONCLUSIONS For patients undergoing elective surgery of the pancreas, liver, stomach, and esophagus, considerable differences in demographic factors, frequency, and kind of NI exist. The consequences of NI force surgeons to analyze pre-operative risk factors carefully, assess indications for operation thoroughly, and optimize all controllable parameters.

Abstract
BACKGROUND The increasing use of focussed parathyroidectomy is attributed to introduction of intraoperative parathyroid hormone measurement (ioPTH) and novel preoperative imaging techniques. This study assesses the early postoperative and long-term outcomes of surgery and the value of standardised ioPTH in patients undergoing surgery for primary hyperparathyroidism (pHPT). METHODS From 01/01/1996 to 09/30/2011, all consecutive patients undergoing surgery for pHPT were documented. Data of this observational study were retrospectively evaluated. Patients were subdivided into 2 groups: A.) use of Quick Intraoperative Intact PTH Assay (n = 142; "ioPTH group") vs. B.) control group ("CG", n = 44). For clinical long-term follow-up, also pre- and postoperative signs, symptoms and findings of the initial 43 patients obtained during the first 4 years of the study were semiquantitatively compared. RESULTS 186 consecutive operations for pHPT were performed - in particular, 73 sole parathyroidectomies; 113 combined thyroid and parathyroid resections. Mean operation time was 87 (SD ± 48) min for parathyroidectomy and 120 (SD ± 49) min for combined resections. A persisting hypercalcaemia was found in 16 patients (8.6%) while postoperative elevation of serum calcium and parathormone occurred in 7 patients (3.8%). Postoperative hypocalcaemia was present in 35 patients (18.8%). Differences between both groups regarding hypocalcaemia (p = 1.0), hypercalcaemia (p = 0.67), hyperparathyrinaemia (p = 0.12) and rate of reintervention (p = 0.055) were not significant. Thirty nine of the initial 43 patients reported one or more signs of pHPT (90.7%). Most frequent symptoms were nephrolithiasis (41.9%), back pain (51.2%), discomfort in the upper abdomen (41.9%), fatigue (41.9%) and general weakness (61.1%). Follow-up investigations (mean, 4.7 [range, 3.2-6.5] years) revealed that 65 % of patients reported improvement of general condition, 27% had no change and 8% reported deterioration. CONCLUSIONS IoPTH is now standard in parathyroid surgery. Value of ioPTH correlates directly with selected centre-specific intraoperative criteria. The stricter the criteria the more reliable is the exclusion of multiglandular disease. Surgery for pHPT was performed with a very low complication rate. Through the long-term follow-up, nearly two thirds of patients benefited from the operation.

Abstract
Surgical site infections are the second or third most common type of nosocomial infections in Germany. For hospitals an annual incidence of 130000-160000 cases is estimated. Microbiological findings basically depend on type of surgery and wound location. A variety of risk factors is known. Discrimination of avoidable and unavoidable risk factors is the key for prevention. Most important points in prevention are perioperative prophylaxis with antibiotics 30-60 minutes prior to incision and strict asepsis in the operation room. Clinical findings include a variety of symptoms. They can be assigned to an early course or a definitive infection. However, wound scores are better applicable when comparing clinical studies. The most important therapeutic procedure is clearing the source of infection. Subsequently the wound can be closed by secondary intention or lead to open wound healing. An accompanying therapy with antibiotics is recommendable in case of advanced local or systemic infection. To document wounds is an essential part of treating wounds.

Abstract
BACKGROUND The open abdomen (OA) is a severe disease pattern accompanied by high morbidity and mortality. It is either result of a surgical dis-ease or approach. The aim of this review article is to provide a systematic overview on the options of a temporary closure of the abdominal wall including early and late consequences in the treatment of an open abdomen based on the current medical literature. METHODS Topic-related, selective, PubMed-based literature search of the last decade including historically relevant references combined with own clinical experiences. RESULTS The initial course is marked by problems in intensive care. The most frequent causes of -death are ventilatory problems, acute renal fail-ure, persisting infections and sepsis as well as multiorgan failure. Intensive care duration ranges from 13 to 65 days. Perioperative mortality is account-ed for 10-52 %. Specific complications can be seen in surviving patients such as enteroatmospheric fistula (1.3-41 %), ventral hernia (32-100 %), intraabdominal abscess formation (2.1-21 %), intestinal adhesions and digestion disturbances, neurological und psychological problems (approximately 20 %) as well as heterotopic ossification (17-25 %). DISCUSSION Application of a temporary abdominal closure aims to avoid those complications. Furthermore, time and effort for care and treatment are recommended to be reduced as patients comfort should be improved, simultaneously. Primary fascial closure is of utmost importance to reach this goal. Procedures with highest fascial closure rate (Wittmann patch, STAR, 75-93 %; dynamic retention sutures, 61-91 %; V.A.C., 69-84 %) have lowest mortality. CONCLUSION Type and severity of the various early and late consequences in the treatment of an open abdomen are substantially determined by the complication-inducing causes and the basic disease as well as by the options of an efficient, even in some cases temporary closure of the abdominal wall.

Abstract
Postoperative wound infections are the third most common type of nosocomial infection in German emergency hospitals after pneumonia and urinary infections. They are associated with increased morbidity and mortality, prolonged hospital stay and increased costs. The most important risk factors include the microbiological state of the skin surrounding the incision, delayed or premature prophylaxis with antibiotics, duration of surgery, emergency surgery, poorly controlled diabetes mellitus, malignant disease, smoking and advanced age. Anesthesiological measures to decrease the incidence of wound infections are maintaining normothermia, strict indications for allogenic blood transfusions and timely prophylaxis with antibiotics. Blood glucose concentrations should be kept in the range of 8.3-10 mmol/l (150-180 mg/dl) as lower values are associated with increased complications. Intraoperative and postoperative hyperoxia with 80% O(2) has not been shown to effectively decrease wound infections. The application of local anesthetics into the surgical wound in clinically relevant doses for postoperative analgesia does not impair wound healing.

Abstract
Based on a representative selection of relevant references, the aim of this study was to reflect the change of the algorithm in the surgical management of desmoid tumours (DT) in cases of accompanying familial adenomatous polyposis (FAP). Main focus is concerned with the basics of differential treatment, including additional considerations on epidemiology, diagnosis, outcome and follow-up. DT are rare benign tumours that do not metastasise but tend to invade locally. In contrast to the general population, DT in patients with FAP are more common, show a different pattern of tumour sites and cause considerable morbidity and mortality. Most DT occur in the abdominal cavity and account for the majority of serious problems. Genetic disposition and hormonal factors as well as prior surgical trauma are considered causative for the development of DT. Characteristic symptoms are abdominal pain, nausea and vomiting but DT may also present as acute abdomen. CT scan determines localisation and extension of the tumour. Treatment includes various strategies of medication, surgical resection and radiation. Data concerning diagnostic and therapeutic procedures are based on studies with small case series or case reports only. Therefore data from international multicentre studies are necessary for improving the prognosis and developing reliable and stringent guidelines.

Abstract
PURPOSE Familial adenomatous polyposis is an autosomal-dominant inherited disease with development of as many as thousands of adenomas within colon and rectum. All untreated patients will develop colorectal adenocarcinoma. A variety of extracolonic manifestations can occur, although malignant tumors are rare. An association of familial adenomatous polyposis and sarcomas was reported in a few cases only. METHODS We present the exceptional case of a 24-year-old male with genetically verified familial adenomatous polyposis (deletion of 10 base pairs at position 228-237 of exon 15A). The patient underwent prophylactic subtotal proctocolectomy and ileal-pouch rectal anastomosis in 2003. Two years later, an obstruction of the left ureter caused by a retroperitoneal mass was diagnosed. RESULTS Histopathologic findings after complete tumor resection showed a low-grade fibromyxoid sarcoma. CT scan and clinical follow-up through 15 months postoperatively revealed no recurrent tumor growth. CONCLUSIONS To our knowledge, this is the first reported case of familial adenomatous polyposis with metachronous retroperitoneal fibromyxoid sarcoma. Proctocolectomy or total colectomy and complete tumor resection is the treatment of choice in this case. In addition to more common semimalignant retroperitoneal desmoid tumors in familial adenomatous polyposis patients, a malignant soft-tissue tumor also has to be considered for differential diagnosis.

Abstract
Difficult wounds of different origin are a challenge for medical and custodial knowledge and capability. They are often characterised by a complex and protracted course of disease and cause considerable costs. Critical wounds particularly include chronic wounds such as venous stasis ulcers, diabetic foot ulcers or pressure ulcers and often lead to physical and psychosocial strain. Large-scale and deep wounds, wounds in traumatised tissue, wound complications and infections as well as wounds in patients with severe accompanying diseases or in patients of old age are often marked by a severe and unpredictable course and are therefore a threat for patients. Knowledge of characteristic symptoms and particularities of the course of disease are essential for early diagnosis and succsessful treatment. Despite many recent advances in wound care the management is often compounded by a lack of clearly defined, comprehensive wound care standards.

Abstract
BACKGROUND Conventional nails rely on interlocking screws for axial and rotational stability. Such screws have poor fixation in patients with poor bone quality (osteopenia). The Fixion nail does not depend on interlocking screws-axial and rotational stability is instead achieved by nail expansion. Therefore, this nail may be better suited for patients with poor bone quality who require humeral stabilization. METHODS The system was used to manage 25 unstable humerus shaft fractures in osteoporotic bone. An antegrade approach was used in 18 patients and a retrograde approach was used in 7 patients. RESULTS There were no intra- or postoperative complications. Postoperatively, all fractures were stable and had healed by week 16. The mean operative time was 35 +/- 10 minutes (+/- SD) including 1.5 +/- 0.5 minutes of fluoroscopy time. CONCLUSION The results of this study show that use of this nailing system is associated with minimal complications, predictable fracture healing, and excellent functional outcomes in a cohort of elderly patients with poor bone quality and humeral shaft fractures requiring stabilization. Further confirmation by larger prospective trials is necessary.

Abstract
Traumatic instability of the sternoclavicular joint is a rare condition. It can be treated by surgical cerclage fixation, which necessitates postoperative immobilization, an approach preventing early postoperative functional rehabilitation. Balser plate stabilization is a therapeutic alternative that does not require extended periods of immobilization. From January 1, 1996, to December 31, 2000, a total of 10 trauma patients with unstable sternoclavicular joints (Allman grade III) requiring surgical management were treated with Balser plate stabilization to allow early physiotherapy. The population included 7 patients with anterior dislocations, 2 with posterior dislocations, and 1 with medial epiphysiolysis in addition to posterior dislocation. Implants were removed from 9 patients after 3 months and 1 patient after 2 months. One year or longer after the procedure, 9 of 10 patients were available for follow-up; 1 patient had moved. The results achieved with this alternative treatment are excellent. There were no cases of redislocation. The only surgical complication was a seroma that required surgical drainage. One patient had arthrosis develop. Outcome was assessed with Constant (range, 84-100; mean, 90.2 +/- 6.6) and DASH (disabilities of the arm, shoulder, and hand) (range, 4.1-16.6; mean, 8.4 +/- 1.4) scores. For the rare case of sternoclavicular joint dislocation requiring open surgical reduction and stabilization, the Balser plate technique is reliable, permits early movement, has good postoperative results, and compares favorably with alternative methods.

Abstract
BACKGROUND People with metastatic fracture of the humerus are of poor general health. Often they are not able to compensate the handicap of an impaired extremity. Standard osteosynthetic techniques are not always applicable. To reduce the trauma of the operation, we used the Fixion expandable nail system. METHODS At two centers, 23 metastatic fractures of the humerus (in 22 patients) were stabilized with a new nailing system. The nail expands under hydraulic pressure up to 150% of its uninflated diameter, gaining long frictional contact to the bone. All patients were followed up until osseous healing occurred or until they died. RESULTS AND CONCLUSIONS The operative time was approximately 32 min, including 1.4 min fluoroscopy time. Nail insertion is brief and therefore not very stressful to the group of debilitated patients who require this intervention. Immediately postoperatively, the upper extremity is stable to permit physiotherapy. In these few patients, we saw no complications. The advantages of the surgical approach appear to outweigh those of conservative management options if a simple and safe surgical technique makes the humerus stable enough to resist normal daily loads.
