Mid-term functional and quality of life outcomes of robotic and laparoscopic ventral mesh rectopexy: multicenter comparative matched-pair analyses.

BACKGROUND: The aim of this study was to compare patients' mid-term functional and quality of life (QoL) outcomes following robotic ventral mesh rectopexy (RVMR) and laparoscopic ventral mesh rectopexy (LVMR). METHODS: The data of consecutive female patients who underwent minimally invasive ventral mesh rectopexy for external or symptomatic internal rectal prolapse at 3 hospitals in Finland between January 2011 and December 2016 were retrospectively collected. Patients were matched by age and diagnosis at a 1:1 ratio. A disease-related symptom questionnaire was sent to all living patients at follow-up in July 2018. RESULTS: After a total of 401 patients (RVMR, n = 187; LVMR, n = 214) were matched, 152 patients in each group were included in the final analyses. The median follow-up times were 3.3 (range 1.6-7.4) years and 3.0 (range 1.6-7.6) years for the RVMR and LVMR groups, respectively. The postoperative QoL measures did not differ between the groups. Compared with the LVMR group, the RVMR group had lower postoperative Wexner Incontinence Score (median 5 vs. median 8; p < 0.001), experienced significant ongoing incontinence symptoms less often (30.6% vs. 49.0%; p < 0.001) and reported less postoperative faecal incontinence discomfort evaluated with the visual analogue scale (median 11 vs. median 39; p = 0.005). RVMR patients had a shorter hospital stay (2.2 days vs. 3.8 days; p < 0.001) but experienced more frequent de novo pelvic pain (31.8% vs. 11.8%; p < 0.001). CONCLUSION: RVMR and LVMR patients had equal functional and QoL outcomes. Those who underwent RVMR had lower mid-term anal incontinence symptom scores but suffered more frequent de novo pelvic pain.

Redo ventral rectopexy: is it worthwhile?

BACKGROUND: Minimally invasive ventral mesh rectopexy (VMR) is a widely used surgical treatment for posterior pelvic organ prolapse; however, evidence of the utility of revisional surgery is lacking. Our aim was to assess the technical details, safety and outcomes of redo minimally invasive VMR for patients with external rectal prolapse (ERP) recurrence or relapsed symptoms of internal rectal prolapse (IRP). METHODS: This is a retrospective cohort study of patients with recurrent ERP or symptomatic IRP who underwent redo minimally invasive VMR between 2011 and 2016. The study was conducted at three hospitals in Finland. Data collected retrospectively included patient demographics, in addition to perioperative and short-term postoperative findings. At follow-up, all living patients were sent a questionnaire concerning postoperative disease-related symptoms and quality of life. RESULTS: A total of 43 redo minimally invasive VMR were performed during the study period. The indication for reoperation was recurrent ERP in 22 patients and relapsed symptoms of IRP in 21 patients. In most operations (62.8%), the previously used mesh was left in situ and a new one was placed. Ten (23.3%) patients experienced complications, including 2 (4.7%) mesh-related complications. The recurrence rate was 4.5% for ERP. Three patients out of 43 were reoperated on for various reasons. One patient required postoperative laparoscopic hematoma evacuation. Patients operated on for recurrent ERP seemed to benefit more from the reoperation. CONCLUSIONS: Minimally invasive redo VMR appears to be a safe and effective procedure for treating posterior pelvic floor dysfunction with acceptable recurrence and reoperation rates.

Restored pelvic anatomy is preserved after laparoscopic and robot-assisted ventral rectopexy: MRI-based 5-year follow-up of a randomized controlled trial.

AIM: Our aim was to compare the long-term anatomical outcomes between robot-assisted ventral mesh rectopexy (RVMR) and laparoscopic ventral mesh rectopexy (LVMR) for external or internal rectal prolapse. METHOD: This study is a follow-up of a single-centre randomized controlled trial (RCT). Thirty patients were randomly allocated to RVMR (n = 16) or LVMR (n = 14). The primary end-point was maintenance of the restored pelvic anatomy 5 years after the operation, as assessed by magnetic resonance (MR) defaecography. Secondary outcome measures included the Pelvic Organ Prolapse Quantification (POP-Q) measures and functional results assessed using symptom questionnaires. RESULTS: Twenty-six patients (14 RVMR and 12 LVMR) completed the 5-year follow-up and were included in the study. The MRI results, POP-Q measurements and symptom-specific quality of life measures did not differ between the RVMR and LVMR groups. The MRI measurements of the total study population remained unchanged between 3 months and 5 years. In the Pelvic Floor Distress Inventory (PFDI-20), the RVMR group had lower symptom scores (mean 96.0, SD 70.7) than the LVMR group (mean 160.6, SD 58.9; P = 0.004). In the subscales of pelvic organ prolapse (POPDI-6) (mean 23.2, SD 24.3 vs mean 52.4, SD 22.4; P = 0.001) and the Colorectal-Anal Distress Inventory (CRADI-8) (mean 38.4, SD 23.3 vs mean 58.6, SD 25.4; P = 0.009), the patients in the RVMR group had significantly better outcomes. CONCLUSION: After VMR, the corrected anatomy was preserved. There were no clinically significant differences in anatomical results between the RVMR and LVMR procedures 5 years after surgery based on MR defaecography. However, functional outcomes were better after RMVR.

Cost-analysis and quality of life after laparoscopic and robotic ventral mesh rectopexy for posterior compartment prolapse: a randomized trial.

BACKGROUND: The aim of this study was to assess, whether robotic-assistance in ventral mesh rectopexy adds benefit to laparoscopy in terms of health-related quality of life (HRQoL), cost-effectiveness and anatomical and functional outcome. METHODS: A prospective randomized study was conducted on patients who underwent robot-assisted ventral mesh rectopexy (RVMR) or laparoscopic ventral mesh rectopexy (LVMR) for internal or external rectal prolapse at Oulu University Hospital, Finland, recruited in February-May 2012. The primary outcomes were health care costs from the hospital perspective and HRQoL measured by the 15D-instrument. Secondary outcomes included anatomical outcome assessed by pelvic organ prolapse quantification method and functional outcome by symptom questionnaires at 24 months follow-up. RESULTS: There were 30 females (mean age 62.5 years, SD 11.2), 16 in the RVMR group and 14 in the LVMR group. The surgery-related costs of the RVMR were 1.5 times higher than the cost of the LVMR. At 3 months the changes in HRQoL were 'much better' (RVMR) and 'slightly better' (LVMR) but declined in both groups at 2 years (RVMR vs. LVMR, p > 0.05). The cost-effectiveness was poor at 2 years for both techniques, but if the outcomes were assumed to last for 5 years, it improved significantly. The incremental cost-effectiveness ratio for the RVMR compared to LVMR was €39,982/quality-adjusted life years (QALYs) at 2 years and improved to €16,707/QALYs at 5 years. Posterior wall anatomy was restored similarly in both groups. The subjective satisfaction rate was 87% in the RVMR group and 69% in the LVMR group (p = 0.83). CONCLUSIONS: Although more expensive than LVMR in the short term, RVMR is cost-effective in long-term. The minimally invasive VMR improves pelvic floor function, sexual function and restores posterior compartment anatomy. The effect on HRQoL is minor, with no differences between techniques.

A prospective pilot study on MRI visibility of iron oxide-impregnated polyvinylidene fluoride mesh after ventral rectopexy.

BACKGROUND: Magnetic resonance imaging (MRI) provides excellent information about pelvic anatomy after ventral rectopexy, but the position of the conventional mesh is not seen constantly. Iron oxide-impregnated polyvinylidene fluoride (PVDF) meshes are proven to have MRI visibility in hernia or vaginal reconstructive surgery. This prospective pilot study was designed to assess the visualization, position, and shape of the magnetic resonance (MR)-visible synthetic pelvic mesh used in minimally invasive ventral rectopexy. METHODS: Eight patients with pelvic organ prolapse were recruited for laparoscopic (LVMR) or robotic-assisted ventral mesh rectopexy (RVMR) with a synthetic MR-visible PVDF mesh. A follow-up visit was scheduled at 3 months after surgery. MR imaging was performed to evaluate the position and dimensions of the mesh and anatomical result. The visibility of the mesh in each sequence was assessed subjectively. RESULTS: The visibility of the mesh was best on T1-weighted flash images. The mesh was also well visualized on T2-weighted sagittal images. T2-weighted images, in general, provided best visualization of the surrounding anatomical structures and enabled assessment of the mesh fixation. CONCLUSIONS: T2 sagittal and T1-weighted flash images provide the best information about the position and integrity of the iron oxide-impregnated PVDF mesh after LVMR or RVMR with a short examination time.

Building-related symptoms are linked to the in vitro toxicity of indoor dust and airborne microbial propagules in schools: A cross-sectional study.

INTRODUCTION: Indoor microbial toxicity is suspected to cause some building-related symptoms, but supporting epidemiological data are lacking. OBJECTIVE: We examined whether the in vitro toxicity of indoor samples from school buildings was associated with work-related health symptoms (building-related symptoms, BRS). METHODS: Administrators of the Helsinki City Real Estate Department selected 15 schools for the study, and a questionnaire on symptoms connected to work was sent to the teachers in the selected schools for voluntary completion. The cellular toxicity of classroom samples was determined by testing substances extracted from wiped indoor dust and by testing microbial biomass that was cultured on fallout plates. Boar sperm cells were used as indicator cells, and motility loss was the indicator for toxic effects. The effects were expressed as the half maximal effective concentration (EC50) at which >50% of the exposed boar sperm cells were immobile compared to vehicle control. RESULTS: Completed symptom questionnaires were received from 232 teachers [median age, 43 years; 190 (82.3%) women] with a median time of 6 years working at their school. Samples from their classrooms were available and were assessed for cellular toxicity. The Poisson regression model showed that the impact of extracts of surface-wiped school classroom dust on teacher work-related BRS was 2.8-fold (95% CI: 1.6-4.9) higher in classrooms with a toxic threshold EC50 of 6µgml-1 versus classrooms with insignificant EC50 values (EC50 >50µgml-1); P<0.001. The number of symptoms that were alleviated during vacation was higher in school classrooms with high sperm toxicity compared to less toxic sites; the RR was 1.9 (95% CI: 1.1-3.3, P=0.03) for wiped dust extracts. CONCLUSIONS: Teachers working in classrooms where the samples showed high sperm toxicity had more BRS. The boar sperm cell motility inhibition assay appears promising as a tool for demonstrating the presence of indoor substances associated with BRS.

Mortality rates for Finnish anaesthesiologists and paediatricians are lower than those for the general population.

BACKGROUND: Previous studies on mortality among anaesthesiologists in the Nordic countries have reported inconsistent results. In an effort to examine mortality patterns among Finnish anaesthesiologists, we compared anaesthesiologists and paediatricians with the general population. METHODS: The year of birth and mortality data for anaesthesiologists and paediatricians deceased during the period 1996-2014 were assembled from the membership files maintained by the Finnish Medical Association. Data for the general population and causes of death were obtained from the database of Statistics Finland. Standardized mortality ratios (SMR) for anaesthesiologists and paediatricians were calculated using the general population as a reference. RESULTS: During the follow-up period, there were 62 deaths among anaesthesiologists and and 95 among peadiatricians. Anaesthesiologists had a lower mean age at death (66.9 years) than did peadiatricians (76.2 years). Standardized mortality ratios for both the groups were well below 1.0. The rate of suicides for anaesthesiologists was more than three times higher than that for paediatricians and more than five times higher for that of the general population. DISCUSSION: We found no evidence of increased mortality for anaesthesiologists or paediatricians. The number of suicides among anaesthesiologists was higher than among paediatricians and the general population.

Has the income of the residential area impact on the use of intensive care?

BACKGROUND: The socioeconomic factors have an impact on case mix and outcome in critical illness, but how these factors affect the use of intensive care is not studied. The aim of this study was to evaluate the incidence of intensive care unit (ICU) admissions in patients from residential areas with different annual incomes. METHODS: Single-center, retrospective study in Northern Finland. All the non-trauma-related emergency admissions from the hospital district area were included. The postal codes were used to categorize the residential areas according to each area's annual median income: the low-income area, €18,979 to €28,841 per year; the middle-income area, €28,879 to €33,856 per year; and the high-income area, €34,221 to €53,864 per year. RESULTS: A total of 735 non-trauma-related admissions were included. The unemployment or retirement, psychiatric comorbidities and chronic alcohol abuse were common in this population. The highest incidence, 5.5 (4.6-6.7)/1000/year, was in population aged more than 65 years living in high-income areas. In working-aged population, the incidence was lowest in high-income areas (1.5 (1.3-1.8/1000/year) compared to middle-income areas (2.2 (1.9-2.6)/1000/year, P = 0.001) and low-income areas (2.0 (1.7-2.4)/1000/, P = 0.009). Poisonings were more common in low-income areas. There were no differences in outcome. CONCLUSION: The incidence of ICU admission in working-aged population was 25% higher in those areas where the annual median income was below the median annual income of €38,775 per inhabitant per year in Finland.

Evaluating helicopter emergency medical missions: a reliability study of the HEMS benefit and NACA scores.

BACKGROUND: The benefits of the Helicopter Emergency Medical Service (HEMS) and dispatch accuracy are continuously debated, and a widely accepted score to measure the benefits of the mission is lacking. The HEMS Benefit Score (HBS) has been used in Finnish helicopter emergency medical services, but studies are lacking. The National Advisory Committee for Aeronautics (NACA) score is widely used to measure the severity of illness or injury in the pre-hospital setting, but it has many critics due to its subjectivity. We investigated the inter-rater and rater-against-reference reliability of these scores. METHODS: Twenty-five fictional HEMS missions were created by an expert panel. A total of 22 pre-hospital physicians were recruited to participate in the study from two different HEMS bases. The participants received written instructions on the use of the scores. Intraclass correlation coefficients (ICCs) and mean differences between rater-against-reference values were calculated. RESULTS: A total of 17 physicians participated in the study. The ICC was 0.70 (95% CI 0.57-0.83) for the HBS and 0.65 (95% CI 0.51-0.79) for the NACA score. Mean differences between references and raters were -0.09 (SD 0.72) for the HBS and 0.28 (SD 0.61) for the NACA score, indicating that raters scored some lower NACA values than reference values formed by an expert panel. CONCLUSION: The HBS and NACA score had substantial inter-rater reliability. In addition, the rater-against-reference values were acceptable, though large differences were observed between individual raters and references in some clinical cases.

Robot-assisted vs laparoscopic ventral rectopexy for external or internal rectal prolapse and enterocele: a randomized controlled trial.

AIM: The purpose of this prospective randomized study was to compare robot-assisted and laparoscopic ventral rectopexy procedures for posterior compartment procidentia in terms of restoration of the anatomy using magnetic resonance (MR) defaecography. METHOD: Sixteen female patients (four with total prolapse, twelve with intussusception) underwent robot-assisted ventral mesh rectopexy (RVMR) and 14 female patients (two with prolapse, twelve with intussusception) laparoscopic ventral mesh rectopexy (LVMR). Primary outcome measures were perioperative parameters, complications and restoration of anatomy as assessed by MR defaecography, which was performed preoperatively and 3 months after surgery. RESULTS: Patient demographics, operation length, operating theatre times and length of in-hospital stay were similar between the groups. The anatomical defects of rectal prolapse, intussusception and rectocele and enterocele were similarly corrected after rectopexy in either technique as confirmed with dynamic MR defaecography. A slight residual intussusception was observed in three patients with primary total prolapse (two RVMR vs one LVMR) and in one patient with primary intussusception (RVMR) (P = 0.60). Rectocele was reduced from a mean of 33.0 ± 14.9 mm to 5.5 ± 8.4 mm after RVMR (P < 0.001) and from 24.7 ± 17.5 mm to 7.2 ± 3.2 mm after LVMR (P < 0.001) (RVMR vs LVMR, P = 0.10). CONCLUSION: Robot-assisted laparoscopic ventral rectopexy can be performed safely and within the same operative time as conventional laparoscopy. Minimally invasive ventral rectopexy allows good anatomical correction as assessed by MR defaecography, with no differences between the techniques.

Early chest computed tomography in adult acute severe community-acquired pneumonia patients treated in the intensive care unit.

BACKGROUND: The value of early chest computed tomography (CT) was evaluated among severe community-acquired pneumonia (SCAP) patients. METHODS: The study population consisted of 65 of 457 SCAP patients with concomitant chest CT and radiograph performed within 48 h of ICU admission. Each image pair was re-evaluated by two radiologists. The type of pneumonia, the presence of pleural fluid and atelectasis were assessed. Therapeutic and diagnostic procedures induced by CT results were analysed together with clinical, microbiological and outcome data. RESULTS: Alveolar pneumonia was observed in 72.3% of patients by radiograph and in 75.4% of patients by CT. Pleural fluid was detected via chest radiograph and CT in 17 (26.2%) and 41 cases (63.1%), (P < 0.001) and atelectasis in 10 (15.4%) and 22 cases (33.8%), (P = 0.002), respectively. In 34 patients (52.3%), the CT revealed 38 new findings (58.5%) not shown in plain chest radiograph. Out of these 34 patients, therapeutic interventions or procedures were performed in 26 (76.5%). The number of infected lobes correlated negatively with the lowest PaO2 /FiO2 ratio (ρ = -0.326, P = 0.008) for chest CT scans. CONCLUSION: Compared with chest radiograph, chest CT generated new findings in nearly 60% of SCAP patients, leading to new procedures or changes in medical treatment in nearly 75% of those patients. Chest CT better describes the pulmonary involvement and severity of oxygenation disorder compared to a plain chest radiograph.

Fatal injuries in rural and urban areas in northern Finland: a 5-year retrospective study.

BACKGROUND: Finland has the fourth highest injury mortality rate in the European Union. To better understand the causes of the high injury rate, and prevent these fatal injuries, studies are needed. Therefore, we set out to complete an analysis of the epidemiology of fatal trauma, and any contributory role for alcohol, long suspected to promote fatal injuries. As a study area, we chose the four northernmost counties of Finland; their mix of remote rural areas and urban centres allowed us to correlate mortality rates with 'rurality'. METHODS: The Causes of Death Register was consulted to identify deaths from external causes over a 5-year time period. Data were retrieved from death certificates, autopsy reports and medical records. The municipalities studied were classified as either rural or urban. RESULTS: Of 2915 deaths categorized as occurring from external causes during our study period, 1959 were eligible for inclusion in our study. The annual crude mortality rate was 54 per 100,000 inhabitants; this rate was higher in rural vs. urban municipalities (65 vs. 45 per 100,000 inhabitants/year). Additionally, a greater number of pre-hospital deaths from accidental high-energy trauma occurred in rural areas (78 vs. 69%). 42% of all pre-hospital deaths occurred under the influence of alcohol. CONCLUSION: The crude mortality rate for fatal injuries was high overall as compared to other studies, and elevated in rural areas, where pre-hospital deaths were more common. Almost half of pre-hospital deaths occurred under the influence of alcohol.

Laparoscopic ventral rectopexy in male patients with external rectal prolapse is associated with a high reoperation rate.

BACKGROUND: Laparoscopic ventral rectopexy has been used to treat male patients with external rectal prolapse, but evidence to support this approach is scarce. The aim of this study was to evaluate the results of this new abdominal rectopexy surgical technique in men. METHODS: This was a retrospective multicenter study. Adult male patients who were operated on for external rectal prolapse using ventral rectopexy in five tertiary hospitals in Finland between 2006 and 2014 were included in the study. Patient demographics, detailed operative, postoperative and short-term follow-up data were collected from patient registers in participating hospitals. A questionnaire and informed consent form was sent to all patients. The questionnaire included scores for anal incontinence, obstructed defecation syndrome, urinary symptoms and sexual dysfunction. The main outcome measure was the incidence of recurrent rectal prolapse. Surgical morbidity, the need for surgical repair due to recurrent symptoms and functional outcomes were secondary outcome measures. RESULTS: A total of 52 adult male patients with symptoms caused by external rectal prolapse underwent ventral rectopexy. The questionnaire response rate was 64.4 %. Baseline clinical characteristics and perioperative results were similar in the responder and non-responder groups. A total of 9 (17.3 %) patients faced complications. There were two (3.8 %) serious surgical complications during the 30-day period after surgery that necessitated reoperation. None of the complications were mesh related. Recurrence of the prolapse was noticed in nine patients (17 %), and postoperative mucosal anal prolapse symptoms persisted in 11 patients (21 %). As a result, the reoperation rate was high. Altogether, 17 patients (33 %) underwent reoperation during the follow-up period due to postoperative complications or recurrent rectal or mucosal prolapse. According to the postoperative questionnaire data, patients under 40 had good functional results in terms of anal continence, defecation, urinary functions and sexual activity. CONCLUSIONS: Laparoscopic ventral rectopexy is a safe surgical procedure in male patients with external prolapse. However, a high overall reoperation rate was noticed due to recurrent rectal and residual mucosal prolapse. This suggests that the ventral rectopexy technique should be modified or combined with other abdominal or perineal methods when treating male rectal prolapse patients.

Epidemiology of Achilles tendon ruptures: increasing incidence over a 33-year period.

We investigated the epidemiology of total Achilles tendon ruptures and complication rates after operative and nonoperative treatments over a 33-year period in Oulu, Finland. Patients with Achilles tendon ruptures from 1979 to 2011 in Oulu were identified from hospital patient records. Demographic data, treatment method, and complications were collected retrospectively from medical records. Overall and sex- and age-specific incidence rates were calculated with 95% confidence intervals (CIs). The overall incidence per 100,000 person-years increased from 2.1 (95% CI 0.3-7.7) in 1979 to 21.5 (95% CI 14.6-30.6) in 2011. The incidence increased in all age groups. The mean annual increase in incidence was 2.4% (95% CI 1.3-4.7) higher for non-sports-related ruptures than for sports-related ruptures (P = 0.036). The incidence of sports-related ruptures increased during the second 11-year period whereas the incidence of non-sports-related ruptures increased steadily over the entire study period. Infection was four times more common after operative treatment compared with nonoperative treatment, re-rupture rates were similar. The incidence of Achilles tendon ruptures increased in all age groups over a 33-year period. Increases were mainly due to sports-related injuries in the second 11-year period and non-sports-related injuries in the last 11-year period.

Lower respiratory tract virus findings in mechanically ventilated patients with severe community-acquired pneumonia.

BACKGROUND: The role of viral infections in the etiology of severe community-acquired pneumonia (SCAP) was prospectively evaluated from 2008 to 2012 at a university-level intensive care unit. METHODS: Clinical data and microbiological tests were assessed: blood cultures, urine pneumococcal and legionella antigens, Mycoplasma pneumoniae and Chlamydia pneumoniae antibodies from paired serums, and respiratory virus detection by multiplex, real-time polymerase chain reaction (PCR) from nasopharyngeal swabs and lower tracheal specimens via intubation tube. RESULTS: Of 49 mechanically ventilated SCAP patients (21 men and 28 women; median age, 54 years), the etiology was identified in 45 cases (92%). There were 21 pure bacterial infections (43%), 5 probably pure viral infections (10%), and 19 mixed bacterial-viral infections (39%), resulting in viral etiology in 24 patients (49%). Of 26 viruses, 21 (81%) were detected from bronchial specimens and 5 (19%) from nasopharyngeal swabs. Rhinovirus (15 cases, 58%) and adenovirus (4 cases, 15%) were the most common viral findings. The bacterial-viral etiology group had the highest peak C-reactive protein levels (median, 356 [25th-75th percentiles, 294-416], P = .05), whereas patients with probably viral etiology had the lowest peak procalcitonin levels (1.7 [25th-75th percentiles, 1.6-1.7]). The clinical characteristics of pure bacterial and mixed bacterial-viral etiologies were comparable. Hospital stay was longest among the bacterial group (17 vs 14 days; P = .02). CONCLUSIONS: Viral findings were demonstrated in almost half of the SCAP patients. Clinical characteristics were similar between the pure bacterial and mixed bacterial-viral infections groups. The frequency of viral detection depends on the availability of PCR techniques and lower respiratory specimens.

Histological damage of colonic epithelium is associated with clinical severity and outcome in colectomized critically Ill patients.

BACKGROUND: Severe intestinal mucosal damage and organ failure has been associated in experimental models. Our purpose was to determine whether there is any association between histopathological findings and postoperative mortality among ICU patients undergoing emergency colectomies for various illnesses. METHODS: In a retrospective case control study, total colectomy specimens from 50 patients in a mixed ICU were analysed: 18 had sepsis, 11 vascular operations, and 21 Clostridium difficile colitis. Overall thickness, the width of epithelial defects, and presence of cryptal damage were assessed. Extent of necrosis and amount of neutrophils were separately evaluated in the layers of the colonic wall. Clinical features, including sequential organ failure assessment (SOFA) scores and survival, were registered. RESULTS: The histopathological findings for the three clinical entities were similar, except for the abundance of characteristic pseudomembranes in the Clostridium group. Mucosal height (maximum) showed a negative correlation with SOFA score on admission (ρ = -0.296, P = 0.037), and with preoperative blood lactate level (ρ = -0.316; P = 0.027). The nonsurvivors had wider enterocyte defects (60 vs. 40.8, P = 0.002) and more severe crypt damage (61 vs. 27 %; P = 0.024) than the survivors. CONCLUSIONS: The histopathological damage involves all layers of the colon wall among ICU patients being largely similar in sepsis, C. difficile infection, and ischemia after vascular operations. Mucosal epithelial damage is associated with clinical severity of the illness and mortality.

Robotic-assisted and laparoscopic ventral rectopexy in the treatment of rectal prolapse: a matched-pairs study of operative details and complications.

BACKGROUND: Laparoscopic ventral rectopexy has been proven to be safe and effective in the treatment of rectal prolapse or intussusception. Robotic-assisted surgery may offer potential benefits to this operation. This study describes the comparison of robotic-assisted and conventional laparoscopic ventral rectopexy in terms of clinical parameters, operative details, postoperative complications and short-term outcomes. METHODS: Twenty patients operated on for rectal prolapse or intussusception using the Da Vinci Surgical System (Intuitive Surgical Inc, Sunnyvale CA, USA) were prospectively followed for 3 months. The cases were pair-matched with laparoscopically operated controls from registry files. RESULTS: Mean operating time was 159 min (standard deviation; ±37 SD) and 153 min (±33 SD) and mean total time in the operating theatre 231 min (±39 SD) and 234 min (±41 SD) for robotic-assisted and laparoscopic operations, respectively. Mean blood loss was 25 ml (±49 SD) in robotic-assisted and 37 ml (±50 SD) in laparoscopic procedures. There was one (5 %) significant complication in each group. Mean length of hospital stay was 3.1 (±2 SD) and 3.3 (±1.3 SD) days for the robotic-assisted and laparoscopic groups, respectively. The subjective benefit rate was the same in both groups: 16/20 (80 %). One patient in the robotic-assisted group continued to have symptoms of obstructed defecation, and there was one recurrence of prolapse in the laparoscopic group. CONCLUSIONS: Robotic-assisted laparoscopic ventral rectopexy is safe, feasible and not more time consuming than the laparoscopic technique even at the beginning of the learning curve. The short-term results are comparable with those of laparoscopy. We found no arguments to support the routine use of robotic assistance in rectopexy operations.

Laparoscopic versus hybrid approach for treatment of incisional ventral hernia: a 5-10-year follow-up of the randomized controlled multicenter study.

PURPOSE: In this long-term follow-up of a prospective, randomized, and multicenter study, we compare the results of a group receiving laparoscopic incisional ventral hernia repair using intraperitoneal onlay mesh (LG) to a group receiving a hybrid hernia repair where open closure of fascial defect was added to intraperitoneal mesh placement (HG). METHODS: Originally, 193 patients with 2-7 cm incisional hernias were randomly assigned to either the LG or HG during the 30-month recruitment period in 2012 to 2015. Long-term follow-up was conducted 5-10 years after surgery to evaluate hernia recurrence rate and quality of life (QoL). RESULTS: In all, 65 patients in the LG and 60 in the HG completed the long-term follow-up with a median follow-up period of 87 months. Recurrent hernia was detected in 11 of 65 patients (16.9%) in the LG and 10 of 60 patients (16.7%) in the HG (p > 0.9). Kaplan-Meier analysis demonstrated a recurrence rate approaching 20% in both groups, with similar curves. Three patients in the LG (4.6% and five patients in the HG (8.1%) had undergone re-operation due to recurrence (p = 0.48). There was no difference in patient-reported QoL measured using the SF-36 questionnaire. Mean pain scores were similar between groups, mean numeric rating scale (NRS) 0 to 10 being 1.1 in the LG and 0.7 in the HG (p = 0.43). CONCLUSION: Fascial closure did not reduce hernia recurrence rate in this study population, even though it has been shown to be beneficial and recommended in surgery guidelines. In the long term, recurrence rate for both groups is similar.

Severe community-acquired pneumonia treated with ß-lactam-respiratory quinolone vs. ß-lactam-macrolide combination.

BACKGROUND: This study aimed to compare the outcome of patients with severe community-acquired pneumonia (SCAP) treated with the combination of either ß-lactam-quinolone (ßQ) or ß-lactam-macrolide (ßM) antibiotics. METHODS: We retrospectively studied a cohort of patients with SCAP treated from January 2000 to December 2010 at a mixed university-level intensive care unit (ICU). APACHE II score, SCAP severity assessed by IDSA/ATS score, first antibiotic treatment initiated during the initial 24 h of admission, ICU and hospital length of stay (LOS), and ICU, hospital, 30 and 60-day mortalities were assessed. RESULTS: Altogether, 210 patients with SCAP were analyzed, 104 in the ßQ arm and 106 in the ßM arm. Median APACHE II scores on admission were higher in the ßM group (22 vs. 18, P = 0.003). More patients in the ßQ group required mechanical ventilation (63.1% vs. 42.5%, P = 0.004) and fulfilled IDSA/ATS SCAP criteria (n = 87; 83.7%) than those in the ßM group (n = 73; 68.9%; P = 0.015). Thirty-day mortality was 16.3% in the ßQ group and 24.5% in the ßM group (P = 0.17), and with septic shock mortality was 19.6% and 32.6%, respectively (P = 0.16). On APACHE II and IDSA/ATS SCAP score adjusted multivariate logistic regression analysis, the ßM group had a slightly higher but not significant odds ratio (OR) for a 30-day mortality compared to the ßQ group (OR 1.4; 95% CI, 0.62-3.0; P = 0.44). CONCLUSION: Thirty-day mortality rate of SCAP patients did not differ whether they were treated with either ßQ or ßM combination.

Serum markers of collagen synthesis and degradation in acute respiratory failure patients.

BACKGROUND: Procollagen-derived propeptides reflect the rate of collagen synthesis and type I cross-linked collagen telopeptides (ICTP) collagen I degradation. We studied the collagen metabolism to find out if changes seen in acute respiratory distress syndrome patients are observed in patients with acute respiratory failure (ARF), and whether multiple organ dysfunction (MOD) has impact on it. METHODS: ARF patients with prolonged hospitalisation at least 21 days were included to the study. Blood samples for serum procollagen aminoterminal propeptide I (PINP) and III (PIIINP), and ICTP measurements were collected at study admission (day 0) and on days 2, 7, and 21. RESULTS: The study population comprised 68 patients. Forty-three patients (63%) developed MOD during the first week. PIIINP levels increased in all patients over time. The increase was slightly more pronounced in patients with MOD. During the first week, the synthesis of PIIINP increased more than PINP, and PINP degradation exceeded its production. By day 21, the balance of collagen metabolites returned to baseline. CONCLUSION: The collagen metabolism was altered in ARF patients. The first week was dominated by degradation of type I collagen and production of type III collagen, but by day 21, the collagen composition returned to more stable form.
