Abstract
Due to logistic, organizational and economic advantages, interdisciplinary emergency centers are gaining more and more acceptance compared to established, discipline-specific and independent emergency rooms. Organizational concepts for interdisciplinary emergency centers need to consider the mandate for comprehensive patient care and the consequential performance spectrum. Thus, the implementation of generally accepted guidelines and specifications is demanding.Currently developed concepts of the accordant interdisciplinary working groups try to fulfill these premises. Further fundamental criteria to be met are the quality and education of medical and nursing staff, which are predominantly doing their jobs within the interdisciplinary emergency centers. The concept of the German surgical societies and connected organizations is not the implementation of a new definition of the role of emergency specialized physicians but rather a substantial advancement of the existing and established regulations for further education. Therefore, a further advanced-training program for clinical emergency medicine has to be implemented in addition to the existing emergency education within the common trunk, which every physician has to pass through during discipline-specific education. Furthermore, this program should complement the existing pre-clinical emergency education, which can be acquired after specialization.The accordant criteria to be developed and the coordination with the German Medical Association (Bundesärztekammer) are currently prioritized on the agenda of the interdisciplinary working group. Due to reasons of compatibility with the regulations for further education, specific management skills for future heads and directors of such interdisciplinary emergency centers should not be stipulated within the advanced-training program for clinical emergency medicine but should be gained through specific course concepts beyond this program.

Abstract
BACKGROUND To date laparoscopic hepatic surgery is only common in a few centres for a specific selected patient group. The intention of this survey was to estimate the current state of affairs for laparoscopic hepatic surgery in Germany at 2008. MATERIALS AND METHODS A questionnaire was prepared and sent out by e-mail in May 2009 to the members of the DGAV (German Society of General and Visceral Surgery). The feedback was evaluated anonymously. RESULTS A total of 181 answers were received by 31st July 2009 (return rate of 15.9%). The return rate of basic and standard care hospitals was 9.2%, specialized hospitals 23.6%, hospitals with maximum care 50% and university hospitals had a return rate of 71.9%. The question whether laparoscopic hepatic surgery had been performed in 2008 was answered with YES by 125 (69.1%) and NO by 54 (29.8%) members. The number of laparoscopic hepatic surgery interventions (laparoscopic ultrasound, laparoscopic radiofrequency ablation and resection) in 2008 was given as more than 50 by 4 (2.2%) hospitals, between 20 and 50 by 11 (6.1%) hospitals, between 10 and 20 by 23 (12.7%) hospitals, between 5 and 10 by 45 (24.9%) hospitals and between 0 and 5 by 54 (29.8%) hospitals. In 2008 the frequency of laparoscopic ultrasound during intraoperative staging to confirm the diagnosis ranged from 2 to 250, whereby 96.4% of the hospitals had less than 50 and only 2 hospitals (2.7%) had 211 and 250 examinations, respectively. 50 hospitals carried out laparoscopic radiofrequency ablation (RFA). 69 (38.1%) of the interviewed hospitals reported hepatic laparoscopic resections (n=551). CONCLUSION Laparoscopic liver surgery has been done in Germany in patients with benign or malignant liver lesions. Pure laparoscopy is the most common access. Atypical resections are the primarily indication followed by left lateral resections. All further types of resection have been done in a very small number. Laparoscopic liver surgery has been performed in all types of hospitals.

Abstract
Purpose Diverticula of the esophagus represent a rare pathological entity. Distinct classifications of the disease imply different surgical concepts. Surgery should be reserved for symptomatic patients only. Minimally invasive surgery (MIS) for treatment of esophageal diverticula encompasses rigid and flexible intraluminal endoscopy, thoracoscopy and laparoscopy. We here give an overview on the pathogenesis of esophageal diverticula, the minimally invasive surgical techniques for treatment and the recent literature. Additionally, we present our own experience with MIS for midthoracic diverticula. Methods We analyzed the cases of patients who underwent MIS for midthoracic diverticula with regard to preoperative symptoms, perioperative and follow-up data. Results Three patients (two female, one male, age 79, 78 and 59 years) received thoracoscopic surgery for midthoracic diverticula. All patients reported of dysphagia and regurgitation. In two patients pH-investigation showed pathological reflux but manometry was normal in all patients. Operating time was 205, 135 and 141 minutes. We performed intraoperative intraluminal endoscopy in all patients. There were no intraoperative complications and although no surgical complications occured postoperatively one patient developed pneumonia which advanced to sepsis and lethal multi organ failure. Upon follow-up the two patients did not have recurrent diverticula or a recurrence of previous symptoms. Conclusions Surgery for diverticular disease of the esophagus has been associated with high rates of morbidity and mortality. Despite the lethal non-surgical complication we encountered, with regard to recent publications minimally invasive apporaches to treat patients with symptomatic esophageal diverticula entail lower rates of complications with better long term results in comparison to open surgery.

Abstract
BACKGROUND/AIMS Laparoscopic Radiofrequency-ablation is a safe and effective method for tumor destruction in patients with unresectable liver tumors. However, accurate probe placement using laparoscopic ultrasound guidance is required to achieve complete tumor ablation. After development and evaluation of laparoscopic navigation tools for radiofrequency ablation, we are now presenting a prototype of a navigation- and documentation-system for laparoscopic RFA. METHODOLOGY An image-guided surgery system for laparoscopic liver treatments (LapAssistent) based on a 3D-navigation scene was developed. A laparoscopic ultrasound probe and a RFA needle could be navigated using an electromagnetic tracking system. The system was studied using a perfused tumour-mimic-model of a porcine liver. RESULTS The study showed that laparoscopic ultrasound-guided navigation is technically feasible. The system enables the surgeon to intraoperatively update the three-dimensional planning data in case of new findings. The RFA needle could be placed accurately in a targeted tumour with a targeting error ranging from 5 - 7 mm, even out of the ultrasound plane. In case of multiple tumours lying in close spatial relationship, the documentation module helps to keep track of the already ablated tumours and those that still need to be treated. DISCUSSION Laparoscopic radiofrequency ablation requires advanced laparoscopic ultrasound skills for accurate placement of the RFA probe. The system adds benefit to laparoscopic RFA enabling the surgeon to place the needle accurately inside the targeted tumours using the navigation scene. The possibility to update the three-dimensional model with new intraoperative findings enables the surgeon to adapt to a new intraoperative situation.

Abstract
Abstract Clinical studies have shown that probiotics influence gastrointestinal motility, e.g. Escherichia coli Nissle 1917 (EcN) (Mutaflor) proved to be at least as efficacious as lactulose and more potent than placebo in constipated patients. As the underlying mechanisms are not clarified, the effects of EcN culture supernatants on human colonic motility were assessed in vitro. Human colonic circular smooth muscle strips (n = 94, 17 patients) were isometrically examined in an organ bath and exposed to different concentrations of EcN supernatants. Contractility responses were recorded under (i) native conditions, (ii) electrical field stimulation (EFS), (iii) non-adrenergic non-cholinergic conditions, and (iv) enteric nerve blockade by tetrodotoxin (TTX). As concentrations of acetic acid were increased in EcN supernatants, contractility responses to acetic acid were additionally tested. EcN supernatants significantly increased the maximal tension forces both at low and high concentrations. Neither blockade of both adrenergic and cholinergic nerves nor application of TTX abolished these effects. EFS-induced contractility responses were not altered after exposure to EcN supernatants. Acetic acid elicited effects comparable to EcN supernatants only under TTX conditions. EcN supernatants modulate in vitro contractility of the human colon. As neither partial nor TTX blockade of enteric nerves abolished these effects, EcN supernatants appear to enhance colonic contractility by direct stimulation of smooth muscle cells. Active metabolites may include other substances than acetic acid, as acetic acid only partially resembled the effects elicited by EcN supernatants. The data provide a rationale for therapeutical application of probiotics in gastrointestinal motility disorders.

Abstract
BACKGROUND The aim of this study was to assess the results of laparoscopic stoma creation for fecal diversion, specifically focussing on feasibility, safety, and efficacy, as well as indications and techniques. METHODS Within a 10-year-period, all patients requiring laparoscopic stoma creation were evaluated prospectively. Patients' profiles and indications, procedures and results of operation, conversion, morbidity, mortality and short-term complications (stoma-related, laparoscopy-associated) were analyzed. RESULTS A total of 80 patients (39 males, 41 females) with a mean age of 55.5 years (range, 17-91) underwent laparoscopic stoma creation. Most common indications were unresectable advanced colorectal cancer (n=20), pelvic malignant cancer (e. g. ovarian, cervix and prostate cancer, n=16), and perianal Crohn's disease with complex fistulas (n=16). Only in one female patient with pelvic malignant disease was the procedure converted to laparotomy due to obesity (conversion rate, 1.3%). 79 patients underwent laparoscopic stoma creation (completion rate, 98.7%) including loop ileostomy (n=30), loop sigmoid colostomy (n=40) and end sigmoid colostomy (n=9). Postoperative complications were documented in 9 patients (overall morbidity rate, 11.4%), including 4 minor complications treated conservatively (2 cases of prolonged atonia and 1 case each of pneumonia and urinary tract infection) and 5 major complications requiring reoperation (reoperation rate, 6.3%): one parastomal abscess (drainage), one stoma retraction following rod dislocation (laparoscopic stoma recreation), small bowel obstruction in two patients (small bowel resection), one port-site hernia (fascial closure), and hemorrhage (managed by re-laparoscopy). Mean operation time was 74 min (range, 30-245 min). Mean blood loss volume was 80 ml (range, 30-400 ml). Patients were discharged from hospital after a mean of 10.3 days (range, 3-47). Within a 1-year follow-up, no further stoma complications were documented. CONCLUSIONS The advantages of laparoscopic stoma creation are low morbidity and reoperation rates, and no procedure-related mortality; our results suggest that laparoscopic stoma creation for fecal diversion is safe, feasible and effective. Therefore, at our institution, laparoscopic stoma creation is the method of choice for fecal diversion.

Abstract
The study was designed to compare patients after laparoscopic and conventional colectomy with regard to early postoperative mood, cognitive function, and neurocognitive variables S100β and neuron-specific enolase (NSE). Forty-five laparoscopic and 25 open colectomies were enrolled into the prospective study. Outcome measurements were positive and negative postoperative mood (BSKE), neuropsychological tests (Trail-Making Test; word reproduction; Stroop Test), and serum biochemical parameters (S100β; NSE). Following laparoscopic procedure, patients described significantly better positive mood ( P < .05), tended to require less time in the Trail-Making Test and Stroop Test, and had lower postoperative serum concentrations of S100β compared to conventional colectomy patients ( P < .01). The current results revealed several group differences, which, in their entirety, seem to represent a more beneficial outcome after laparoscopic colonic surgery.

Abstract
BACKGROUND AND AIMS The aim of this study was to determine the prognostic role of matrix metalloproteinases in rectal cancer. MATERIALS AND METHODS Formalin-fixed and paraffin-embedded tissue sections of 94 rectal carcinomas were used for the immunohistochemical analysis of matrix metalloproteinases (MMP)-2, MMP-7, MT1-MMP, and tissue inhibitor of metalloproteinases (TIMP)-2. Inclusion criteria were sporadic rectal adenocarcinoma resected curatively (including total mesorectal excision), adjuvant radiochemotherapy in UICC stages II and III, and complete intra-institutional follow-up. Results of immunohistochemistry were correlated with clinical and histopathologic data from the prospective rectal cancer registry and prognosis. End points of the prognostic analysis were tumor progression caused by local and/or distant recurrence and 5-year survival (disease-free and overall). To assess prognostic significance, statistics included univariate and multivariate analysis (p<0.05 statistically significant). RESULTS Of the 94 rectal carcinomas, 35% (33/94) showed an epithelial MMP-2 expression, 77% (72/94) were MMP-2 positive in the stroma. Fifty-four percent (51/94) were MMP-7 positive, and 47% (46/94) were positive for both MT1-MMP and TIMP-2. The stromal MMP-2 staining pattern was correlated with the depth of invasion (pT status, p=0.006) with MMP-7 (p=0.016) and TIMP-2 expression (p=0.036). Positive expression of MMP-2 in tumor epithelium was correlated with MMP-7 (p=0.027), MT1-MMP (p=0.036), and TIMP-2 expression (p<0.0001). A positive staining pattern of MMP-7 was significantly correlated with depth of invasion and TIMP-2 (p<0.01). The positive staining pattern of MT1-MMP was correlated with epithelial MMP-2 (p=0.036), MMP-7 (p=0.004), and TIMP-2 expression (p=0.002). TIMP-2 immunoreactivity correlated with depth of invasion (p=0.013), epithelial MMP-2 (p<0.001), stromal MMP-2 (p=0.036), MMP-7 (p<0.001), and MT1-MMP (p=0.002). Neither pattern correlated with age, gender, tumor stage (UICC), grading, preoperative serum carcinoembryonic antigen (CEA) level, or nodal status (p>0.05). Within a mean follow-up of 46 months, tumor progression, caused by either local recurrence or distant metastasis, occurred in 14 patients (15.4%). There was no significant association between the MMP expression and the incidence of local and/or distant recurrence. In terms of survival, preoperative CEA level (disease-free 5-year survival 46% with increased CEA vs 70% with normal CEA, p=0.01; overall 5-year survival 43 vs 74%, p<0.01) and UICC stage were the only factors to be significantly related to 5-year survival by univariate analysis, whereas the metalloproteinases failed to show a significant association. In multivariate analysis, CEA and UICC stage were not identified as independent factors predictive of survival. CONCLUSION MMP-2, MMP-7, MT1-MMP, and TIMP-2 do not appear to be significant predictors of prognosis in a homogenous collective of curatively resected rectal adenocarcinomas.

Abstract
BACKGROUND Because of the creation of a pneumoperitoneum, impairment of ventilation is a common side-effect during laparoscopic surgery. Electrical impedance tomography (EIT) is a method with the potential for becoming a tool to quantify these alterations during surgery. We have studied the change of regional ventilation during and after laparoscopic surgery with EIT and compared the diagnostic findings with computed tomography (CT) scans in a porcine study. MATERIALS AND METHODS After approval by the local animal ethics committee, six pigs were included in the study. Two laparoscopic operations were performed [colon resection (n=3) and fundoplicatio (n=3)]. The EIT measurements (6th parasternal intercostal space) were continuously recorded by an EIT prototype (EIT Evaluation Kit, Dräger Medical, Lübeck, Germany). To verify ventilatory alterations detected by EIT, a CT scan was performed postoperatively. RESULTS Ventilation with defined tidal volumes was significantly correlated to EIT measurements (r2=0.99). After creation of the pneumoperitoneum, lung compliance typically decreased, which agreed well with an alteration of the distribution of pulmonary ventilation measured by EIT. Elevation of positive end-inspiratory pressure reopened non-aerated lung areas and showed a recovery of the regional ventilation measured by EIT. Additionally, we could detect pulmonary complications by EIT monitoring as verified by CT scans postoperatively. CONCLUSION EIT monitoring can be used as a continuous non-invasive intraoperative monitor of ventilation to detect regional changes of ventilation and pulmonary complications during laparoscopic surgery. These EIT findings indicate that surgeons and anesthetists may eventually be able to optimize ventilation directly in the operating theatre.

Abstract
The functional-anatomic structure of the liver according to Couinaud classification based on the intrahepatical course of the vascular structures is the basis of all modern liver surgery. Consequently, the use of intraoperative ultrasound is an undisputed requirement for every liver resection. Exact following of the planned resection plane can be realized only with the application of permanent online navigation based on intraoperative ultrasound during the dissection of the hepatical tissue. Now that the authors have established ultrasound navigated resection in open liver surgery using a navigated parenchymal dissecting instrument, they intend to transfer this technique from open to laparoscopic liver surgery. A special adapter was developed to connect an ultrasound-based navigation system to laparoscopic instruments. The authors present the first results in terms of technical aspects and feasibility.

Abstract
AIMS Radiofrequency ablation is gaining popularity as the interventional therapy of choice for unresectable hepatic malignancies. However, little attention has been paid to the importance of operator experience in this therapy. This study aims to evaluate the results of RFA treatment dependent on operator experience and learning curve. PATIENTS AND METHODS Between 2/2000 and 11/2004 we have undertaken 116 RFA procedures to ablate 404 unresectable primary or metastatic liver tumours in 84 patients. The clinical data of all patients were recorded prospectively and treatment results of the first 42 patients (group I) and the second 42 patients (group II) were compared. All patients were treated by the same surgeon or interventional radiologist. RESULTS RFA was performed percutaneously in 44 procedures (group I n = 35, group II n = 9), via laparotomy in 64 procedures (group I n = 27, group II n = 37) and via laparoscopy in eight procedures (group I n = 1, group II n = 7). The complication rate was comparable in both groups with 7.9% in group I and 7.5% in group II. Group II had a higher complete ablation rate (96.2 vs 93.7%) than group I. One- and two-year survival rates of 92 and 89% in group II were significantly higher than in group I with 69 and 46% (p = 0.015). CONCLUSION By the experience conditional optimization of indication and performance by a specialized RFA team the results could be improved significantly. The data on hand speak for a considerable learning curve in the RFA and demonstrate the importance of the experience of the therapist for the outcome of the patients.

Abstract
INTRODUCTION The aim of this study was to compare functional outcome after transvaginal, transperineal and transrectal repair of a symptomatic rectocele and to develop the ideal surgical approach. PATIENTS AND METHOD 28 patients (27 female, 1 male) who had undergone rectocele repair from 1996 to 2003 were analysed. Mean age was 59 years (range 30-79 years), follow-up was 24 months (range 3 to 70 months) and mean appearance of symptoms was 4 years prior to the operation (6 months-32 years). Transvaginal repair was performed in 13 cases, transperineal repair in 8 cases and transrectal repair in 7 cases. RESULTS 24 of 28 patients (85.7 %) are satisfied with the operation-result (transvaginal 12 of 13 patients [92.3 %], transperineal 7 of 8 patients [87.5 %] and transrectal 5 of 7 patients [71.4 %]). 25 patients (89.3 %) are free of complaints or describe an evident improvement of symptoms (transvaginal 12 of 13 patients [92.3 %], transperineal 7 of 8 patients [87.5 %] und transrectal 6 of 7 patients [85.7 %]). There is one postoperative dyspareunia. DISCUSSION Best treatment of a rectocele starts with patients selection. Considering pelvic floor as functional unity, concomitant urologic-gynaecologic lesions and proximal intraabdominal disturbances the appropriate surgical procedure is selected. CONCLUSION Surgical approach to correct a symptomatic rectocele depends on the concomitant lesion.

Abstract
Systemic mycoses, especially pulmonary diseases and septicemia are observed increasingly at intensive care units. Essential risk factors for development of candidosis are the expanded use of antibiotics and immunocompromised patients, caused either as a result of a severe underlying disease or iatrogenically induced after organ transplantation. Candida albicans is the most frequent pathogen in microbiological findings. Blood cultures are only positive in massive fungemia. We report a 50-year-old patient with recurrent Candida-septicemia: rupture of the distal esophagus after dilatation because of cardiac achalasia with mediastinal emphysema and mediastinitis. Severe acute respiratory distress syndrome after aspiration with septic shock and acute renal failure at the beginning. Long-term mechanical ventilation, continuous renal replacement therapy and multifarious antibiotic therapy. Early microbiological samples of several positive blood cultures and bronchoalveolar lavages revealed the presence of Candida albicans. In the further clinical course, detection of Pseudomonas species in bronchoalveolar lavages and Staphylococci as well as Enterococci in a number of positive blood cultures. Later on development of a severe liver dysfunction with test results that showed an intrahepatic cholestasis. Because of coagulation failure commencement of artificial liver support with the MARS-system (molecule adsorbent recirculating system). Decrease of high bilirubin levels was accompanied by improvement of clinical condition of the patient. In the following course, repeated severe systemic infections with phases of septicemia or rather septic shock and detection of Candida in several positive blood cultures and bronchoalveolar lavages. In each case increasing bilirubin levels with signs of intrahepatic cholestasis and each time improvement with antimycotic therapy (voriconazol, caspofungin and fluconazol). The patient showed more and more signs of immunodeficiency in the sequel. The clinical appearance of candidosis is manifold. Systemic Candida infections are frequent in patients with immunodeficiency. A recurrent Candida septicemia with prolonged respiratory failure and severe liver dysfunction in form of cholestatic hepatosis, that improved several times with antimycotic therapy in combination with evidence based intensive care measures and artificial organ support is a comparatively rare event.

Abstract
Zygomycosis caused by Rhizopus species is an aggressive and rapidly progressive opportunistic fungal infection in immunocompromised patients. It comprises mucocutaneous, rhinocerebral, pulmonary, urological and disseminated infections. Predisposing factors are immunosuppression owing to severe diseases, immunological defects or metabolic disturbances like diabetic ketoacidosis. Rhizopus infections are characterized by angioinvasive growth, necroses of infected tissue and perineural invasion. The histopathologic demonstrable invasion of blood vessels is remarkable for a fungal infection. The mortality of zygomycosis is very high, especially for disseminated disease and when immunosuppression cannot be corrected. We report about two cases of pulmonary zygomycosis, caused by Rhizopus spp.: patient 1, female 73 years old: Delayed clinical course according to hip arthroplasty infection and infection of a femoropopliteal bypass of the right leg, eventually exarticulation of the right hip joint, Pseudomonas pneumonia, severe sepsis caused by staphylococci, acute respiratory distress syndrome (ARDs), acute renal failure and multiple use of antibiotics. Subsequently detection of Rhizopus spp. in the bronchoalveolar lavage and treatment with amphotericin B for this reason. Patient 2, male 68 years old: transplantation of kidney in past medical history, presenting with acute renal failure and with quite a few infections before. In the sequel development of abscessing pneumonia on the right side with a pleural empyema. Rhizopus spp. were detected by microbiological testing in the empyema fluid. These findings required surgical intervention, resection of the lower lobe of the right lung and within the same operation of the renal graft because of rejection. The patient was treated with caspofungin. The further course was delayed by several septic phases. Both patients died later on in spite of all efforts. The very rarely seen pulmonary zygomycosis caused by infection with Rhizopus spp. developed in both patients owing to immunosuppression, in one patient iatrogenically induced by immunosuppressive drugs after organ transplantation, in the other as a result of prolonged severe sepsis. In comparison with other mycoses treatment of Rhizopus infections remains difficult. The affinity to blood vessels, where the fungi multiply, and their feature of vascular invasion with thrombosis and infarction complicate therapeutic efforts.

Abstract
AIMS Thymidylate synthase (TS) and tumor suppressor p53 are two proteins with an influence on tumor resistance to radio-chemotherapy that is well known. For this reason we tested the effect of TS and p53 expression on clinical outcome (tumor recurrence and survival) in patients after curative tumor resection, especially in patients who received adjuvant radio-chemotherapy. PATIENTS AND METHODS A total of 120 patients with colorectal cancer were included in the study. A curative resection was possible in 83 patients, and 30 of this group received adjuvant therapy. For the immunohistochemical staining of tumor specimens, monoclonal antibody (mAb) TS 106 against TS and mAb DO-1 against p53 protein were used. TS positivity was defined as a moderate to high staining intensity in the cytoplasma of cells and p53 positivity as nuclear staining of tumor cells in >10% of these cells. RESULTS Thymidylate synthase immunoreactivity was found in 59% of all cases and p53 staining in 51%. No relation between clinicopathological features and p53 expression was found in contrast to TS expression, where a highly significant association of TS-positive cases with tumor invasion (pT) was observed. Curatively resected patients with a TS-positive tumor developed tumor recurrence/distant metastases significantly more often than TS negative tumors. The same result was found when comparing p53-positive with p53-negative tumors and TS+/p53+ with TS-/p53- tumors. TS expression was highly significantly associated with poor survival and was the strongest independent prognostic factor in multivariate analysis, followed by lymph node status. CONCLUSION Thymidylate synthase expression seems to be an independent prognostic factor and a possible predictor of tumor recurrence in patients with colorectal cancer.

Abstract
One of the most controversial discussions on laparoscopic surgery deals with the question of whether to apply this technique to malignant disease and specifically to rectal cancer. The four major issues are the adequacy of oncologic resection, recurrence rates and patterns, long-term survival and quality of life. There is evidence, from nonrandomized studies, suggesting that margins of excision and lymph node harvest achieved laparoscopically reached comparable results to those known from conventional open resection. Our own experience of laparoscopic surgery on rectal cancer is based on 52 patients treated with curative intent. Focusing on the postoperative long-term run, we gained the following results: The median age of patients was 66.7 years and ranged from 42-88. Anastomotic leakage was seen in 6.1% of cases. In a median follow-up of 48 months (36-136), we reached an overall 3-year survival rate of 93% and a 5-year survival rate of 62%. Local recurrence was 1.9%, distant metastasis occurred in 11.5% of cases. We saw no port-site metastasis. To evaluate functional results following laparoscopic surgery a matched pair analysis was carried out. Matching of patients after laparoscopic and conventional open surgery was performed according to sex, age, type of resection, time period of surgery, and stage of disease classified by UICC. Regarding bladder and sexual dysfunction, using the EORTC QLQ CR38 score we found no statistical significant difference between the examined groups. As far as can be seen, laparoscopic surgery in rectal carcinoma may achieve the same or, in selected patients, even better results than open surgery. However, at present no published study has shown much evidence. Many more studies are necessary to define the place of laparoscopic technique in rectal cancer surgery, regarding appropriate selection of patients and evaluating adjuvant or neoadjuvant treatment in combination with the laparoscopic approach.

Abstract
INTRODUCTION Radio frequency ablation (RFA) represents a new technique for local destruction of liver tumors. Indication and procedure are poorly validated at present. METHOD To record the actual nationwide RFA application in Germany, a survey of 2026 hospitals with standardized questionnaires was conducted. RESULTS With a respond rate of 17.5%, results from 58 hospitals covering 1700 ablated patients were analyzed. In 25.9% of them, RFA is already used in potentially curative resectable tumors, in 22.4% even when incomplete ablation for tumor mass reduction is expected. Of the 58 hospitals, 75% combine resection and RFA to reach a so-called R-0 situation. The maximal tumor sizes they quoted for achieving complete ablation ranged from <3 cm to 11 cm. In contraindications for RFA, the tumor size, number of tumors, critical localization of the tumor, and disorders of liver function were mentioned the most. CONCLUSION This survey documents significant discrepancies in indication, application, procedure, and results in RFA for liver tumors. The lack of general standards and an overestimation of the method may lead to uncritical application, neglect of standard therapy, or unsatisfying results.
