Prehabilitation bundle can reduce incidence of postoperative pulmonary complications.

INTRODUCTION: Elective major colorectal surgery is still associated with postoperative morbidity and mortality. Preoperative optimization can potentially reduce postoperative pulmonary complications, which significantly prolong recovery and increase the risk of mortality. The aim of this study was to evaluate the effect of the prehabilitation bundle on postoperative pulmonary complications. METHODS: All patients undergoing elective colorectal procedure for benign or malignant diagnosis before and after the introduction of the prehabilitation bundle were enrolled in the study. Prehabilitation was focused on nutritional support, regular aerobic and muscle strength exercise, preoperative optimization of anaemia, improvement of oral hygiene including regular chlorhexidine mouth wash, psychological support, restriction of smoking and alcohol consumption. In addition to the general characteristics, compliance with individual measures, incidence of pulmonary complications and length of stay were monitored. RESULTS: A total of 596 patients were included in the study (226 before and 370 after the implementation of the package). After the introduction of prehabilitation, the incidence of postoperative pulmonary complications decreased significantly - 29 (13%) vs. 17 (4.6%), RR: 0.21-0.67), p=0.001 and shorter length of stay was observed à 9.7 (±8.8) to 7.7 (±5.5) days (p=0.0005). Except for optimization of anaemia, compliance with the individual components of the established bundle was very good. CONCLUSION: Introduction of a prehabilitation bundle focused on improvement of cardiorespiratory capacity, optimization of diet and oral hygiene, can reduce the risk of postoperative pulmonary complications and shorten the length of stay.

Potential use of mesenchymal stem cells in the treatment of inflammatory bowel disease - a systematic review of the literature.

INTRODUCTION: The incidence of inflammatory bowel disease is increasing worldwide and, despite advances in conservative and surgical treatment, a significant proportion of patients do not achieve complete remission and have to undergo repeated surgical procedures. Stem cell therapy is a new alternative to immunomodulatory therapy. METHODS: We performed a systematic review of the literature dealing with the use of mesenchymal stem cells for the treatment of IBD. The PubMed database was searched and original studies published between 2015 and 2021 were included. RESULTS: A total of 80 citations were found, of which 21 clinical studies and 47 experimental studies were included in the review. CONCLUSION: The efficacy of MSCs in the treatment of perianal Crohns disease is at least comparable to current therapies. A positive effect of MSC administration has also been demonstrated in animal models of luminal disease or enterocutaneous fistula. The results after systemic administration in IBD patients are still ambiguous. KEY WORDS: inflammatory bowel disease.

Randomized experimental study of two novel techniques for transanal repair of dehiscent low rectal anastomosis.

BACKGROUND: Anastomotic leak after low anterior rectal resection is a dreadful complication. Early diagnosis, prompt management of sepsis followed by closure of anastomotic defect may increase chances of anastomotic salvage. In this randomized experimental study, we evaluated two different methods of trans-anal anastomotic repair. METHODS: A model of anastomotic leak was created in 42 male pigs. Laparoscopic low anterior resection was performed with anastomosis created using a circular stapler with half of the staples removed. Two days later, animals were randomized into a TAMIS (trans-anal minimally invasive surgery) repair, endoscopic suture (ENDO) or control group with no treatment (CONTROL). Signs of intraabdominal infection (IAI), macroscopic anastomotic healing and burst tests were evaluated to assess closure quality after animals were sacrificed on the ninth postoperative day. RESULTS: Closure was technically feasible in all 28 animals. Two animals had to be euthanized due to progressive sepsis at four and five days after endoscopic closure. Healed anastomosis with no visible defect was observed in 10/14 and 11/14 animals in TAMIS and ENDO groups, respectively, versus 2/14 in CONTROL (p < 0.05). Overall IAI rate was significantly lower in TAMIS (4/14; p = 0.006) and ENDO (5/14; p = 0.018) compared to CONTROL (12/14). Burst tests confirmed sealed closure in healed anastomosis with a median failure pressure of 190 (110-300) mmHg in TAMIS and 200 (100-300) mmHg in ENDO group (p = 0.644). CONCLUSION: In this randomized experimental study, we found that both evaluated techniques are effective in early repair of dehiscent colorectal anastomosis with a high healing rate.

Assessment of colorectal anastomosis perfusion with confocal laser endomicroscopy − an experimental study

Introduction: Early diagnosis of complicated healing of colorectal anastomosis can increase the chance for salvage surgery and thus reduce overall morbidity. Confocal laser endomicroscopy (CLE) enables in vivo assessment of tissue perfusion without disturbing its integrity. This experimental study evaluates the potential of CLE for postoperative monitoring of colorectal anastomosis. Methods: A hand-sewn colorectal anastomosis was performed in 9 pigs. The animals were subsequently divided into groups with normal (N=3) and ischemic anastomosis (N=6). Microscopic signs of hypoperfusion were evaluated postoperatively at regular intervals using CLE. Results: Uneven saturation of the images was evident in the group with ischemic anastomosis. The epithelium had inhomogeneous edges and more numerous crypt branching was visible. Tissue oedema quantified as the number of crypts per visual field was already more extensive at the first measurement after induction of ischemia. There was also a significant difference between the values measured before and 10 minutes after ischemia ­ 8.7±1.9 vs. 6.0±1.1 (p=0.013). Conclusion: Postoperative monitoring of the colorectal anastomosis using CLE enables prompt detection of perfusion disorders.

Autologous transplantation of mesenchymal stem cells into the portal vein of the miniature pig; a preliminary experiment for NOTES approach.

INTRODUCTION: There is evidence that mesenchymal stem cells (MSCs) could trans-differentiate into the liver cells in vitro and in vivo and thus may be used as an unfailing source for stem cell therapy of liver disease. Combination of MSCs (with or without their differentiation in vitro) and minimally invasive procedures as laparoscopy or Natural Orifice Transluminal Endoscopic Surgery (NOTES) represents a chance for many patients waiting for liver transplantation in vain. METHODS: Over 30 millions of autologous MSCs at passage 3 were transplanted via the portal vein in an eight months old miniature pig. The deposition of transplanted cells in liver parenchyma was evaluated histologically and the trans-differential potential of CM-DiI labeled cells was assessed by expression of pig albumin using immunofluorescence. RESULTS: Three weeks after transplantation we detected the labeled cells (solitary, small clusters) in all 10 samples (2 samples from each lobe) but no diffuse distribution in the samples. The localization of CM-DiI+ cells was predominantly observed around the portal triads. We also detected the localization of albumin signal in CM-DiI labeled cells. CONCLUSION: The study results showed that the autologous MSCs (without additional hepatic differentiation in vitro) transplantation through the portal vein led to successful infiltration of intact miniature pig liver parenchyma with detectable in vivo trans-differentiation. NOTES as well as other newly developed surgical approaches in combination with cell therapy seem to be very promising for the treatment of hepatic diseases in near future.

Postoperative monitoring of colorectal anastomosis - experimental study.

INTRODUCTION: Inadequate blood supply is one of the major risk factors for colorectal anastomotic leak. Early postoperative detection of local ischemic changes can predict complicated healing and lead to better outcome. Microdialysis (MD) offers real-time evaluation of adequate bowel perfusion through monitoring of tissue metabolism. The aim of this study was to assess the feasibility of MD for early detection of ischemic changes in colorectal anastomosis. METHOD: Five pigs with end-to-end colorectal anastomosis were included. MD catheter was placed intramurally 5mm from anastomotic edge. Occlusive ischemia was induced after 3 measurements and followed by another 3 hours of monitoring. Tissue levels of different metabolites were measured every 60 minutes before and after ischemia induction. Mann-Whitney test was used to compare pre and post ischemic changes. RESULTS: The monitoring of colorectal anastomosis using MD was technically feasible and associated with no complications. Significant changes caused by local ischemia were observed in decreased levels of glucose or pyruvate and increased levels of lactate and glycerol. All metabolic changes were detectable already in first samples 60 minutes after ischemia induction. CONCLUSION: Postoperative ischemic changes in colorectal anastomosis can be detected by means of microdialysis.Key words: colorectal anastomosis anastomotic leak microdialysis.

Fixation of biomaterial to metallic stent and fixation of stents after circular endoscopic dissection in the esophagus on an animal model.

INTRODUCTION: Complete circular endoscopic (submucosal) resection (CER) performed using the endoscopic submucosal dissection (ESD) technique is burdened with a high incidence of post-operative strictures in the esophagus. The most effective method of preventing them is not known so far; one of the possible methods is to prevent these strictures directly at the site of their formation by covering the defect with a stent. The aim of the study was to find a way to fix a selected biomaterial to a stent, and subsequently, to fix the stent at the CER site to prevent esophageal strictures in an animal model. METHOD: Miniature piglets from the Czech Academy of Sciences breeding unit in Libechov (N=10) were used. Endoscopy was performed using a single-channel endoscope. First, we made two circular mucosal cuts spaced 5 cm apart in the middle esophagus and we performed the CER between them using the endoscopic submucosal dissection technique. After that, we covered the defect with a stent coated with biomaterial (Xe-Derma®) while we tried to prevent stent migration into the stomach. For stent fixation, we tested endo-clips (N=3), the Apollo endoscopic system (N=1) and the suspension technique using two polyamide threads (N=6) anchored in the nasal septum. We performed a control endoscopy, stent removal and subsequent autopsy after 12 weeks. RESULTS: All procedures were completed successfully without serious complications or deaths. Although stents covered with Xe-Derma® were applied to the entire resection area, one case of mediastinitis and one paraesophageal abscess were found during autopsy, most likely due to microperforations caused during the procedure. Histological analysis showed that after contact with the biomaterial, re-epithelisation took place within one week of application to the resection area. Stent migration occurred in each case when the stent was attached to the esophageal wall by endo-clips or with the endoscopic suture system (Apollo). There was no stent dislocation in the cases where the stent was suspended by two polyamide threads. CONCLUSION: We developed a technique of fixing biomaterial to the surface of metallic stents which we used to prevent the formation of esophageal strictures after CER. Distal suspension fixation of the stent with a polyamide thread proved to be the most effective, while fixations by endo-clips or with the endoscopic suture system were ineffective.Key words: benign esophageal strictures circular endoscopic resection endoscopic submucosal dissection complication prevention.

[Adherence to reporting guidelines in Perspectives in Surgery]. / Dodrzování publikacních standardu v casopisu Rozhledy v chirurgii.

INTRODUCTION: Reporting guidelines were established to improve the quality of scientific papers. Currently, the most common are CONSORT (Consolidated Standards of Reporting Trials), STROBE (Strengthening the Reporting of Observational Studies in Epidemiology) and CARE (Clinical Consensus-based Case Reporting Guideline). Spin can be defined as (un)intentionally biased interpretation of results aimed at convincing readers of a positive benefit of any given intervention. The aim of the study was to evaluate the adherence of papers published in Perspectives in Surgery to CONSORT, STROBE or CARE and to identify the frequency of spin. METHODS: All articles published between 10/2014 and 9/2016 were analysed. Editorials and letters to editor were excluded. Original papers and case reports were assessed using 12 parameters. Any conclusion not corresponding to outcomes from pre-defined measurements was identified as spin. Descriptive statistics were used. RESULTS: Of 210 articles, 144 (69%) were analysed - 67 (47%) retrospective studies, 3 (2%) prospective studies and 74 (51%) case reports. The studies showed the highest compliance in terms of reporting the cohort size (89%). On the other hand, study limitations were presented in 22%. Performed investigations and interventions were described in all (100%) case reports. Conversely, limitations were not mentioned in any. None of the analysed papers met all of the 12 monitored parameters. Spin was identified in 47 (67%) original articles. CONCLUSION: None of the evaluated papers adhered completely to the current reporting guidelines. Spin occurred in more than 2/3 of the publications.Key words: reporting guidelines spin CONSORT STROBE CARE.

A comparison of two endoscopic closures: over-the-scope clip (OTSC) versus KING closure (endoloop + clips) in a randomized long-term experimental study.

BACKGROUND: Both over-the-scope clip (OTSC) and KING (endoloop + clips) closures provide reliable and safe full-thickness endoscopic closure. Nevertheless, OTSC clip demonstrated significantly inferior histological healing in the short-term follow-up. AIM: To compare OTSC versus KING closure of a perforation with regard to long-term effectiveness and macroscopic and histological quality of healing. METHODS: We performed a randomized experimental study with 16 mini-pigs (mean weight 43.2 ± 11.2 kg). A standardized perforation was performed on the anterior sigmoid wall. KING closure (n = 8) was attained by approximation of an endoloop fixed to the margins of a perforation with endoclips. OTSC closure (n = 8) was performed by deploying OTSC (OVESCO) over the defect. Pigs underwent a control sigmoidoscopy 8 months after the closure to assess the macroscopic quality of healing. Then, autopsy was performed and the rectosigmoid was sent for histopathological assessment. RESULTS: All closures were completed successfully without air leaks. The duration of closure was similar in both techniques (OTSC 17.8 ± 7.6 min vs. KING 19.6 ± 8.8 min). At autopsy, all KING closures (100 %) were healed with a flat scar without signs of leakage. Microscopically, no inflammatory changes were observed after KING closure. In the OTSC group, microscopic ulcers were present in two pigs (25 %), cryptal abscesses in three pigs (38 %) and significant neutrophil accumulation in all eight pigs (P < 0.01). Giant cell granulomas, dysplasia or abundant scarification was not observed in either group. CONCLUSIONS: Both OTSC and KING closures offer a long-term reliable seal of a gastrointestinal perforation without stenosis or fistulas. KING closure provides long-term histologically superior healing.

[Existing laparoscopic simulators and their benefit for the surgeon]. / Laparoskopické simulátory a jejich soucasný prínos pro chirurga.

INTRODUCTION: Nowadays, laparoscopic operations are a common part of surgical practice. However, they have their own characteristics and require a specific method of preparation. Recently, simulation techniques have been increasingly used for the training of skills. The aim of this review is to provide a summary of available literature on the topic of laparoscopic simulators, to assess their contribution to the training of surgeons, and to identify the most effective type of simulation. METHODS: PubMed database, Web of Science and Cochrane Library were used to search for relevant publications. The keywords "laparoscopy, simulator, surgery, assessment" were used in the search. The search was limited to prospective studies published in the last 5 years in the English language. RESULTS: From a total of 354 studies found, we included in the survey 26 that matched our criteria. Nine studies compared individual simulators to one another. Five studies evaluated "high and low fidelity" (a virtual box simulator) as equally effective (EBM 2a). In three cases the "low fidelity" box simulator was found to be more efficient (EBM 2a3b). Only one study preferred the virtual simulator (VR) (EBM2b).Thirteen studies evaluated the benefits of simulators for practice. Twelve found training on a simulator to be an effective method of preparation (EBM 1b3b). In contrast, one study did not find any difference between the training simulator and traditional preparation (EBM 3b). Nine studies evaluated directly one of the methods of evaluating laparoscopic skills. Three studies evaluated VR simulator as a useful assessment tool. Other studies evaluated as successful the scoring system GOALS-GH. The hand motion analysis model was successful in one case. Most studies were observational (EBM 3b) and only 2 studies were of higher quality (EBM 2b). CONCLUSION: Simulators are an effective tool for practicing laparoscopic techniques (EBM: 1b). It cannot be determined based on available data which of the simulators is most effective. The virtual simulator, however, still remains the most self-sufficient unit suitable for teaching as well as evaluation of laparoscopic techniques (EBM 2b3b). Further studies are needed to find an effective system and parameters for an objective evaluation of skills. KEY WORDS: laparoscopy - simulator - surgery assessment.

[Compliance with the procedures of modern perioperative care (Enhanced Recovery After Surgery) at surgery departments in the Czech Republic - results of a national survey]. / Jak jsou dodrzovány postupy moderní perioperacní péce (Enhanced Recovery After Surgery) na chirurgických pracovistích v CR - výsledky národní ankety.

INTRODUCTION: The concept of the enhanced recovery after surgery (ERAS), also called fast-track surgery, is a complex of modern multimodal strategies intended to reduce the perioperative stress response and achieve faster postoperative rehabilitation and rapid recovery of normal physiologic functions. The effect of ERAS on reduction of length of stay and postoperative complications has been proven by randomized controlled trials. The recommendations are supported by substantial evidence, and they are guaranteed by the ERAS society and included in the European Society of Parenteral and Enteral Nutritions (ESPEN) guidelines. The aim of this study was to evaluate the compliance with ERAS protocol in surgical departments in the Czech Republic. MATERIALS AND METHODS: A survey with 19 questions on ERAS measures was sent to 148 surgical departments in the Czech Republic. Answers were anonymous. RESULTS: The overall response rate was 57/148 (38,5%). The indications and proper administration of preoperative nutritional support are performed according to recommendations in 37% respectively 67%. In total, 55% of responders restrict oral intake for more than 6 hours prior to an elective gastrointestinal surgery. A carbohydrate drink is administered preoperatively by 7% of the respondents. A mechanical bowel preparation before surgery is routinely used in 86% of surgical departments. Overall, 52% routinely insert a permanent urinary catheter for 3-5 days and one third of departments left a nasogastric tube in place after the operation. Early postoperative oral intake is restored in 2% of questioned departments. Epidural analgesia is standardly used by 68% respondents. Half of the surgery departments indicate artificial enteral or parenteral nutrition support without any respect to the nutrition status of the patient. CONCLUSION: Protocol of modern perioperative care recommended by ERAS and ESPEN societies should be respected in clinical practice in the Czech Republic. According to the national survey most of the surgical departments do not accept ERAS guidelines. The most challenging procedures include the inadequately long interval of perioperative fasting, use of mechanical bowel preparation and routine insertion of invasions. Early oral intake is, according to the answers, often replaced by artificial enteral or parenteral nutrition.

Comparing over-the-scope clip versus endoloop and clips (KING closure) for access site closure: a randomized experimental study.

BACKGROUND: A safe technique is essential for successful access site closure in Natural Orifice Translumenal Endoscopic Surgery (NOTES) and for closures of iatrogenic perforations. AIM: To compare an over-the-scope clip (OTSC) versus an endoloop + endoclips closure technique (KING closure). METHODS: 40 minipigs underwent NOTES peritoneoscopy with liver biopsy. Gastrotomies and rectotomies were closed with OTSC (n = 20; 10× stomach, 10× rectum) or KING closure (n = 20; 10× stomach, 10× rectum). The animals were euthanized 28 days after the procedure. The main outcome variables were technical feasibility, effectiveness, and healing. RESULTS: Stomach: All but one closure (KING) was successfully completed. The times of closure were similar between the techniques. At necropsy, all access sites were healed. In two animals (1× KING, 1× OTSC), an abscess, probably related to the closure technique, was found. Histologically, transmural healing with muscular bridging was observable in nine pigs for KING versus two pigs for OTSC closure (p = 0.003). Inflammation was present in three pigs for KING versus seven pigs for OTSC closure (p = 0.08). Rectum: All closures were successfully completed. The times of closure were similar between the techniques. At necropsy, all closure sites had healed. Transmural healing with muscular bridging was present in nine pigs for KING versus two pigs for OTSC closure (p = 0.003). Inflammation was present in two pigs for KING versus seven pigs for OTSC closure (p = 0.03). In one animal (OTSC), an enterocolic fistula developed in the proximity of the closure site. CONCLUSIONS: OTSC and KING closure are comparable closure techniques in terms of technical feasibility and effectiveness. KING closure provides a superior histological outcome compared with OTSC closure.

[Quality of life is an important factor in the indication in patients with advanced pancreatic carcinoma--a prospective multicentric study]. / Kvalita zivota je dulezitým faktorem indikacní rozvahy u nemocných s pokrocilým karcinomem pankreatu--multicentrická prospektivní studie.

INTRODUCTION: The aim of this report is to present results of prospective multicentric study on quality of life (QoL) in advanced ductal pancreatic adenocarcinoma patients. MATERIAL AND METHOD: In 426 patients with advanced ductal pancreatic adenocarcinoma, the following parameters were studied: type of treatment, complication rates, 1, 2 and 3-year survival rates. QoL was assessed in 151 patients, using a generic SF-36 questionnaire prior the therapy and then 3 months after the treatment. Arithmetic mean and standard deviation (SD) were used for the QoL pool analysis. The results were evaluated using SF-36 software, t-test for independent samples, ANOVA, paired t-test and SPSS 19.0.1 (IBM Corporation, 2010). The p value < 0.05 was considered as statistically significant. RESULTS: There was a significant difference in the median, 1,2 and 3-year survival rates in the patients with stage III pancreatic cancer who underwent radical resection (RR) compared to the paliative therapy patients (p < 0.001). The highest initial overal QoL value was observed in 39 stage III patients who underwent RR (60.5 +/- 1.84) and no significant decrease in this value was recorded over a 3-month postoperative period (difference--5.1 +/- 16.6, p = 0.064). Paliative therapy resulted in significant reduction in the overall QoL value (p = 0.020). In the paliative therapy group of patients, BDA resulted in significant reduction in the overall QoL value 3 months after the procedure (p = 0.017 vs. ns.). In the group of stage IV patients, nonsignificant increase in the overall QoL value was recorded in 8 patients 3 months after BDA (46.4 +/- 17.0 vs. 51.1 +/- 9.5 p = 0.525). Nonsignificant increase in the overal QoL values was also observed in 18 patients after stent introduction (30.6 +/- 8.3 vs. 31.5 +/- 8.5 p = 0.783). Nonsignificant deterioration in QoL was recorded in patients undergoing exploration, whose initial QoL values corresponded with those in RR patients, while 3 months after the explorative surgery their QoL values were similar to those recorded in the stent group patients (62.0 +/- 16.1 vs. 41.7 +/- 23.6 s rozdílem -20.3 +/- 16.2 p < 0.001). CONCLUSION: Based on the results of the multicentric prospective study in patients with locally advanced stage III and IV ductal pancreatic adenocarcinoma, the following conclusions can be presented: (1) median and 1, 2 and 3-year survival rates in stage III patients were significantly higher in the RR group compared to the paliative therapy patients, (2) initial QoL in stage III patients was significantly the highest in patients who underwent RR. Significant decrease in QoL was recorded in BDA patients. Paliative stent introduction resulted in nonsignificant improvement in the QoL 3 months after the procedure, while the initial QoL values were the lowest in this group, (3) QoL assessment in stage IV patients showed statistically nonsignificant improvement after BDA or stent procedures, the most significant deterioration was observed in the exploration group, (4) no complication which would result in prolongation of the respective hospitalization times was recorded in 67%, (5) early postoperative complications did not result in significant QoL deterioration 3 months after the procedure, (6) absence of chemotherapy results in significant decrease in QoL.

[Fascial closure of the abdominal wall by dynamic suture after topical negative pressure laparostomy treatment of severe peritonitis--results of a prospective randomized study]. / Uzáver steny brisní po laparostomii s pouzitím negativníiho tlaku pro tezkou peritonitidu pomocí dynamické fasciální sutury--výsledky prospektivní randomizované studie.

INTRODUCTION: Severe peritonitis is a frequent condition characterized by high morbidity and mortality rates. Topical negative pressure (TNP) laparostomy could improve the results of the treatment, provided that the adverse events of this method are reduced. The aim of our study was to prove, in a prospective randomized study, that the primary use of TNP laparostomy reduces morbidity and mortality when compared to primary abdominal wall closure after the index surgery for severe peritonitis. The possibility of the abdominal wall fascial closure significantly influencing morbidity was the main topic of this study. MATERIAL AND METHODS: Between 9/2009 and 9/2011,57 patients with severe peritonitis were included in the study at the Department of Surgery of the Bulovka Faculty Hospital; 28 of them were randomized to the TNP laparostomy group and 29 to the primary closure group. The two groups did not differ in age, gender, polymorbidity and severity of peritonitis. RESULTS: The length of hospital stay was similar in both groups (median: 22 days; range 10-171 days) in the intervention group and 23 days (range 3-71) in the control group (p = 0.89). The mortality rate was significantly lower in the TNP laparostomy group in comparison with the primary closure group (3 patients, 11% vs. 12 patients, 41%; p = 0.01). A complete closure of the abdominal wall including fascia and complete abdominal wall healing was achieved in 80% of survivors in the TNP group, compared to 29% in the primary closure group (p = 0.01). No enteral fistula occurred in any surviving patients from both groups. The overall length of abdominal wall healing was significantly shorter in the TNP group (median: 7; 7-94 days, versus 30; 7-223; p = 0.04). CONCLUSIONS: Primary TNP laparostomy is an effective and safe method in the treatment of severe peritonitis. Keeping good clinical practice, especially using dynamic suture as early as after the index surgery and the timely closure of laparostomy as soon as the indication disappears (according to relevant criteria) leads to a significantly higher abdominal wall healing rate, icluding fascial closure, than after peritonitis treatment without laparostomy.

[Antibiotic prophylaxis in acute surgical procedures--the current praxis in Czech Republic]. / Antibiotická profylaxe u akutních chirurgických výkonu--soucasná situace v CR.

INTRODUCTION: Surgical site infections (SSI) are currently one of the most frequent postoperative complications. Emergent surgery is generally subject to a higher risk of SSI. Antibiotic prophylaxis is one of many measures that should be taken to prevent postoperative infection. However, due to possible adverse effects it must be applied only in indicated cases. Many guidelines have been published abroad, but still missing in Czech Republic. Standard use of prophylaxis can be currently followed due to compliance with SCIP (Surgical Care Improvement Project) measurements and reflects the quality of surgical care. OBJECTIVES: The aim of our study was to evaluate the current clinical praxis of prophylactic antibiotic administration in Czech Republic in emergent surgery for diagnosis: acute appendicitis, small bowel obstruction and perforated gastroduodenal ulcer and evaluate the SCIP criteria adherence. METHOD: The survey was sent to 149 surgical departments. The questionnaire included 7 questions and feedback was considered to be anonymous. The compliance with 3 main SCIP measurements (INF-1, INF-2, INF-3) was evaluated by the patients with acute appendicitis as a indication for emergent surgery. RESULTS: Overall, 85 (57%) completed questionnaires were received back. According to a survey results, antibiotic prophylaxis is always administered in 15% of patients operated for acute appendicitis, 27% operated for small bowel obstruction and 47% of patients with gastroduodenal perforation. No prophylaxis is given in 11 (13%) hospitals for either of the mentioned diagnoses. Antibiotics are mostly (46%) administered at induction of general anesthesia and extended to 24 hours. The SCIP measurements adherence was as follows: INF-1--4.7%; INF-2--86%; INF-3--81% of evaluated departments. All of 3 (all-or-none) criteria were fulfilled only at 3 (3.5%) surgical departments. CONCLUSION: The clinical praxis of antibiotic prophylaxis in urgent surgical procedures in Czech Republic is highly variable and mostly ignores the current international guidelines (SCIP). There is a need of local specific guideline concerning antibiotic prophylaxis guaranteed by scientific company.

[Sacral nerve stimulation in the treatment of fecal incontinence--initial experience in the Czech Republic and assessment of functional outcomes]. / Stimulace sakrálního nervu v lécbe fekální inkontinence--první zkusenosti v Ceské republice a hodnocení funkcních výsledku.

INTRODUCTION: During the last decade, sacral nerve stimulation (SNS) has become a new perspective and effective method in the treatment of fecal incontinence. In the Czech Republic, SNSs have been used since 2010. METHODS: From May 2010 to August 2011, sacral nerve stimulation was performed in 15 patients in FN Na Bulovce Surgical Clinic in Prague. All of the subjects were female patients and their mean age was 59 (46-68 years of age). The first phase of the treatment included the following procedures: percutaneous sacral nerve (S2-S4) examination, electrode implantation and subchronic stimulation. Permanent neurostimulator implantation was indicated in 14 out of the 15 subjects and over 50% of them experienced reduction in incontinence episodes. The following neurostimulators were used: Medtronic InterStim 3023 or InterStim II 3058. Stimulation parameters included 15 Hz frequency, pulse width of 210 micros and the stimulation range was between 1-3 V. The patients' follow up period was 1-15 months after the procedure. OUTCOMES: After the first phase of SNS, the morbidy rate was 7%. The morbidity rate after the permanent neurostimulator implantation was 0 %. Permanent neurostimulators were implanted in 14 out of the total of 15 subjects, i.e. the success rate was 93 %. Based on the incontinence recording sheet (diary) data collected from all the 14 subjects, the mean number of incontinence epizodes was 24 epizodes/week (+/- 13.0) before the stimulation and 4 epizodes/week (+/- 3.8) after the stimulation procedure. Cleveland Clinic Incontinence Score was assessed in the first 8 subjects and its mean value was 20 (+/- 0.7) before the procedure, vs. 7 (+/- 1.2) after the stimulation procedure. The both values were significantly lower after the stimulation procedure (p <0.05). No significant differences between the manometric values before the procedure and after the stimulation procedure were detected. SF-36 showed improvement in the quality of life, in particular in the parameters assessing social and mental functions. Nevertheless, there were no significant differences in any of the studied parameters. CONCLUSION: The initial experience with SNS in the Czech Republic showed over 50% improvement in continence rates in 93% of the subjects with introduction of stimulation electrodes and subchronic stimulation and over 50% improvement in 100% of the subjects, who underwent permanent neurostimulator implantations, and full continence was achieved in 33% of the subjects.

[Transrectal hybrid NOTES versus laparoscopic cholecystectomy--a randomized prospective study in a large laboratory animal]. / Transrektální hybridní NOTES versus laparoskopická cholecystektomie--randomizovaná prospektivní studie na velkém laboratorním zvíreti.

INTRODUCTION: NOTES (Natural Orifice Transluminal Endoscopic Surgery) technique was developed to achieve less invasive surgery with the aim to lower frequency of postoperative complications. Cholecystectomy is one of the most frequent elective surgical procedures and is relevant for evaluation of NOTES. The aim of the experimental study was to compare hybrid transrectal and laparoscopic cholecystectomy regarding feasibility and inflammatory response. MATERIAL AND METHODS: A total of 20 pigs weighing 26-56 kg were randomized to laparoscopic or NOTES group. Transrectal approach (15-18 cm from anal edge) was created by needle knife, followed by balloon dilatation and two-channel endoscope was introduced into the abdominal cavity. Cystic artery and duct were clipped and dissected. After extirpation of the gall bladder the colostomy was closed by occlusion loop-and-clip (King' closure) technique. In the laparoscopic group, cholecystectomy was performed by three-port access. Blood samples for evaluation of inflammatory response markers (leukocytes, CRP, interleukin 6) were taken 0, 2nd, 7th and 30th postoperative day, when the experiment ended and pig was euthanized. RESULTS: Two pigs were excluded (1 died early postoperatively for pneumonia, 1 for the rectal closure impossibility after it's laceration during of the gall bladder extirpation). Other pigs survived without complications. Procedure time was significantly longer in NOTES group (134 +/- 27 minutes versus 60 +/- 22 minutes, p < 0.05). White blood cells count and CRP level increased significantly in both groups 2nd and 7th postoperative day and then normalized. Differences between groups were not significant in any of the measured laboratory markers. Sectional finding of exudate and adhesions was comparable in both groups and all transrectal closures were healed. Small subhepatal abscess was found in one pig from NOTES group. CONCLUSION: Transrectal hybrid cholecystectomy is a safe and feasible method with comparable inflammatory responses and longer operating time compared to laparoscopy. A novel loop-and-clip technique was verified as a safe and simple rectal closure.

[Malignant ascites--optional management using hyperthermic peroperative chemotherapy (HIPEC)]. / Maligní ascites--moznost ovlivnení tvorby pomocí hypertermické peroperacní chemoterapie (HIPEC).

UNLABELLED: 146 procedures using hyperthermic intraoperative peritoneal chemotherapy (HIPEC) were performed in 121 patients in the FNB Surgical Clinic, during 2000-2008. During these procedures, ascites was detected in 30 subjects (24.8%) and its volume was 250-11,000 ml. The patients concerned could not undergo radical surgery for their GIT or gynecological tumors. The patient group was divided into two subgroups. Subgroup A (22 subjects) included subjects, in whom at least palliative debulking of the tumors (usually total omentectomy) was feasible, and the procedure was followed by HIPEC. Subgroup B (8 patients) included subjects who could not undergo even the minimum debulking procedure because of extensive tumorous spread in their abdominal cavity, underwent only HIPEC. Out of the total of 22 subjects in Subgroup A, ascites was not postoperatively recorded in 17 patients. In 5 patients, ascites was gradually formed from month 6.3 onwards, however, it only reached subclinical levels. In this subgroup, 7 patients exited (at the mean postoperative month 11.7), the remaining 15 patients were surviving at that time, out of whom 9 patients were surviving for more than 1 year after the procedure, 4 subjects were surviving for over 2 years after the procedure and 2 patients for over 4 years. The geometric mean survival time 16.49 months, standard deviation of 1.57. In Subgroup B (8 patients), no ascites was detected in 3 subjects until their death (37.5%), further 5 subjects presented with ascites at the mean postoperative month 7.25. These patients survived for 2-23 months. The geometric mean survival time was 6.83 months, standard deviation of 2.12. There was a statistically significant difference between the two subgoups in the survival time parametres (p = 0.009), thereas, the difference in ascites relapse rates was statistically insignificant (p = 0.12). In the whole study group, in-hospital morbidity was 16.6% and lethality 3.3%. CONCLUSIONS: HIPEC with/without debulking is an efficient method for controlling, managing or preventing the development of malignant ascites, it extends the mean survival time of the patients (especially when bulking is feasible) with low morbidity and lethality rates of the procedure.

[Intracranial hypertension in acute liver failure and microdialysis]. / Nitrolební hypertenze u akutního jaterního selhání a moznosti mikrodialýzy.

Acute liver failure is a severe condition with a very unfavourable prognosis. One of the common complications and limiting factors for the outcome is the development of the intracranial hypertension. The etiology and the pathogenetic pathways leading to the development of this fatal complication of acute liver failure is still not completely understood. The aim of this review is to inform about the actual knowledge of pathogenesis of the intracranial hypertension in acute liver failure. Finally, a new method of tissue metabolism monitoring--microdialysis--is shortly discussed as a perspective method in monitoring and research on acute liver failure.

[Tolerance of accelerated postoperative rehabilitation following intestinal resections]. / Tolerance akcelerované pooperacní rehabilitace po strevních resekcních výkonech.

INTRODUCTION: Modern procedures in peri-operative care arising from evidence-based medicine improve postoperative results. Their acceptance is however not a common clinical practice at most surgical centers. AIM: The aim of our study was to design a protocol and introduce it into the praxis. The subject of announcement is tolerance of protocol in our conditions. PATIENTS AND METHOD: Prospective randomized study included patients who were operated on (open bowel resection) at Department of Surgery in period 4/2005-12/2007. They were randomized in fast track group (n=53) and non-fast track group (n=52). Protocol with accelerated recovery was used in the fast track group (FTG) and we used traditional approach in the not-fast track (non-FTG). Results were statistically evaluated, 2 patients (FTG) were excluded from analysis for protocol failure (protocol was non kept by anesthesiologist in 1 patient and by the nurse in the second patient). Protocol and informed consent form was approved by the Hospital Ethics Committee. RESULTS: Both groups did not differ in age, diagnosis and length of surgery. Analgesia was controlled significantly better in FTG; similarly oral intake tolerance was higher in this group (day of surgery--mean value 634 ml versus 304 ml). Restoration of bowel functions was also faster in interventional group (mean time 2.1 versus 3.9 days). Frequency of postoperative complications was lower and hospital stay was shorter (median 7.0 versus 9.0 days, p < 0.001). CONCLUSION: Designed fast track protocol of postoperative recovery could be introduced in clinical praxis in terms of study. Patients' tolerance was very good. Application of accelerated recovery procedures is possible in our conditions but it means primarily to overcome worse tolerance of attending personnel.
