Abstract
BACKGROUND Transversus abdominis plane (TAP) block is widely used as a part of pain management after various abdominal surgeries. We evaluated the effect of TAP block as an add-on to the routine analgesic regimen in patients undergoing robot-assisted laparoscopic hysterectomy. METHODS In a prospective blinded study, 70 patients scheduled for elective robot-assisted laparoscopic hysterectomy were randomised to receive either TAP block (ropivacaine 0.5%, 20 ml on each side) or sham block (isotonic saline 0.9%, 20 ml on each side). All patients had patient-controlled analgesia (PCA) with morphine on top of paracetamol and ibuprofen or diclofenac. For the first 24 post-operative hours, we monitored PCA morphine consumption and pain scores with visual analogue scale (VAS) at rest and while coughing. Post-operative nausea and number of vomits (PONV) were recorded. RESULTS Sixty-five patients completed the study, 34 receiving TAP block with ropivacaine and 31 receiving sham block with isotonic saline. We found no differences in median (interquartile range) morphine consumption the first 24 h between the TAP block group [17.5 mg (6.9-36.0 mg)] and the placebo group [17.5 mg (2.9-38.0 mg)] (95% confidence interval 10.0-22.6 mg, P = 0.648). No differences were found for VAS scores between the two groups, calculated as area under the curve/1-24 h, neither at rest (P = 0.112) nor while coughing (P = 0.345), or for PONV between groups. CONCLUSIONS In our study, the TAP block combined with paracetamol and Nonsteroidal anti-inflammatory drugs (NSAID) treatment, had no effect on morphine consumption, VAS pain scores, or frequency of nausea and vomiting after robot-assisted laparoscopic hysterectomy compared with paracetamol and NSAID alone.

Abstract
Background and Aims: A new technique for the repair of inguinal hernia, called Onstep, has been described. This technique places the mesh in the preperitoneal space medially and between the internal and external oblique muscles laterally. The Onstep technique has not yet been described outside the inventors’ departments. This study was based on the first 80 patients operated by the Onstep technique in a general surgical department. The objective of the study was to investigate postoperative pain and complications following the Onstep repair of inguinal hernia. Material and Methods: A total of 80 patients, operated in our department, were followed up in the medical files and contacted by letter. Patients were asked to fill out the Inguinal Pain Questionnaire, Carolinas Comfort Scale, and the Activity Assessment Scale, in order to assess postoperative pain. Results: No perioperative complications occurred. The response rate was 85% on the mailed questionnaires. No patients had any activities they were not able to perform. Activity Assessment Scale results: 80.3% did not have substantial pain-related impairment of daily function. Carolinas Comfort Scale results: 94.8% did not have a symptomatic repair. Inguinal Pain Questionnaire results: 95.5% reported no pain or pain that was easily ignored. Conclusions: It seems from this study that the Onstep technique is a safe method for inguinal hernia repair regarding perioperative and postoperative complications. The postoperative pain seems to be equal to or lower than after the Lichtenstein technique.

Abstract
Abstract
Background
Emergency abdominal surgery carries a considerable risk of death and postoperative complications. Early detection and timely management of complications may reduce mortality. The aim was to evaluate the effect and feasibility of intermediate care compared with standard ward care in patients who had emergency abdominal surgery.
Methods
This was a randomized clinical trial carried out in seven Danish hospitals. Eligible for inclusion were patients with an Acute Physiology And Chronic Health Evaluation (APACHE) II score of at least 10 who were ready to be transferred to the surgical ward within 24 h of emergency abdominal surgery. Participants were randomized to either intermediate care or standard surgical ward care after surgery. The primary outcome was 30-day mortality.
Results
In total, 286 patients were included in the modified intention-to-treat analysis. The trial was terminated after the interim analysis owing to slow recruitment and a lower than expected mortality rate. Eleven (7·6 per cent) of 144 patients assigned to intermediate care and 12 (8·5 per cent) of 142 patients assigned to ward care died within 30 days of surgery (odds ratio 0·91, 95 per cent c.i. 0·38 to 2·16; P = 0·828). Thirty (20·8 per cent) of 144 patients assigned to intermediate care and 37 (26·1 per cent) of 142 assigned to ward care died within the total observation period (hazard ratio 0·78, 95 per cent c.i. 0·48 to 1·26; P = 0·310).
Conclusion
Postoperative intermediate care had no statistically significant effect on 30-day mortality after emergency abdominal surgery, nor any effect on secondary outcomes. The trial was stopped prematurely owing to slow recruitment and a much lower than expected mortality rate among the enrolled patients. Registration number: NCT01209663 (http://www.clinicaltrials.gov).

Abstract
Abstract
Background
The mesh fixation technique in laparoscopic incisional hernia repair may influence the rates of hernia recurrence and chronic pain. This study investigated the long-term risk of recurrence and chronic pain in patients undergoing laparoscopic incisional hernia repair with either absorbable or non-absorbable tacks for mesh fixation.
Methods
This was a nationwide consecutive cohort study based on data collected prospectively concerning perioperative information and clinical follow-up. Patients undergoing primary, elective, laparoscopic incisional hernia repair with absorbable or non-absorbable tack fixation during a 4-year interval were included. Follow-up was by a structured questionnaire regarding recurrence and chronic pain, supplemented by clinical examination, and CT when indicated. Recurrence was defined as either reoperation for recurrence or clinical/radiological recurrence.
Results
Of 1037 eligible patients, 84·9 per cent responded to the questionnaire, and 816 were included for analysis. The median observation time for the cohort was 40 (range 0–72) months. The cumulative recurrence-free survival rate was 71·5 and 82·0 per cent after absorbable and non-absorbable tack fixation respectively (P = 0·007). In multivariable analysis, the use of absorbable tacks was an independent risk factor for recurrence (hazard ratio 1·53, 95 per cent c.i. 1·11 to 2·09; P = 0·008). The rate of moderate or severe chronic pain was 15·3 and 16·1 per cent after absorbable and non-absorbable tack fixation respectively (P = 0·765).
Conclusion
Absorbable tack fixation of the mesh was associated with a higher risk of recurrence than non-absorbable tacks for laparoscopic mesh repair of incisional hernia, but did not influence chronic pain.

Abstract
Circadian- and sleep disturbances may be central for understanding the pathophysiology and treatment of depression. The effect of melatonin on depression/depressive symptoms has been investigated previously. This systematic review assesses the current evidence of a therapeutic- and prophylactic effect of melatonin in adult patients against depression or depressive symptoms. A search was performed in The Cochrane Library, PubMed, EMBASE and PsycINFO for published trials on November 14th 2013. Inclusion criteria were English language, RCTs or crossover trials. Our outcome was measurement of depression/depressive symptoms with a validated clinician-administered or self-rating questionnaire. PRISMA recommendations were followed and the Cochrane risk-of-bias tool used. Ten studies in 486 patients were included in the final qualitative synthesis and four studies, 148 patients, were included in two meta-analyses. Melatonin doses varied from 0.5-6 mg daily and the length of follow-up varied from 2 weeks to 3.5 years. Three studies were done on patients without depression at inclusion, two studies in patients with depression and five studies included a mixture. Six studies showed an improvement in depression scores in both the melatonin and placebo groups but there was no significant difference. One study showed a significant prophylactic effect and another found a significant treatment effect on depression with melatonin compared to placebo. The two meta-analyses did not show any significant effect of melatonin. No serious adverse events were reported. Although some studies were positive, there was no clear evidence of a therapeutic- or prophylactic effect of melatonin against depression or depressive symptoms.

Abstract
AIM Colorectal anastomotic leakage is a serious complication. Despite extensive research, no consensus on the most important preoperative risk factors exists. The aim of this systematic review and meta-analysis was to evaluate risk factors for anastomotic leakage in patients operated with colorectal resection. METHOD The databases MEDLINE, Embase and CINAHL were searched for prospective observational studies on preoperative risk factors for anastomotic leakage. Meta-analyses were performed on outcomes based on odds ratios (OR) from multivariate regression analyses. The Newcastle-Ottawa scale was used for bias assessment within studies, and the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach was used for quality assessment of evidence on outcome levels. RESULTS This review included 23 studies evaluating 110,272 patients undergoing colorectal resection for cancer. The meta-analyses found that a low rectal anastomosis [OR = 3.26 (95% CI: 2.31-4.62)], male gender [OR = 1.48 (95% CI: 1.37-1.60)] and preoperative radiotherapy [OR = 1.65 (95% CI: 1.06-2.56)] may be risk factors for anastomotic leakage. Primarily as a result of observational design, the quality of evidence was regarded as moderate or low for these risk factors according to the GRADE approach. CONCLUSION Based on the best available evidence, important preoperative risk factors for colorectal anastomotic leakage have been identified. Knowledge on risk factors may influence treatment and procedure-related decisions, and possibly reduce the leakage rate.

Abstract
BACKGROUND This article reports on patient-reported sexual dysfunction and micturition symptoms following a randomized trial of laparoscopic and open surgery for rectal cancer. METHODS Patients in the COLOR II randomized trial, comparing laparoscopic and open surgery for rectal cancer, completed the European Organization for Research and Treatment of Cancer (EORTC) QLQ-CR38 questionnaire before surgery, and after 4 weeks, 6, 12 and 24 months. Adjusted mean differences on a 100-point scale were calculated using changes from baseline value at the various time points in the domains of sexual functioning, sexual enjoyment, male and female sexual problems, and micturition symptoms. RESULTS Of 617 randomized patients, 385 completed this phase of the trial. Their mean age was 67·1 years. Surgery caused an anticipated reduction in genitourinary function after 4 weeks, with no significant differences between laparoscopic and open approaches. An improvement in sexual dysfunction was seen in the first year, but some male sexual problems persisted. Before operation 64·5 per cent of men in the laparoscopic group and 55·6 per cent in the open group reported some degree of erectile dysfunction. This increased to 81·1 and 80·5 per cent respectively 4 weeks after surgery, and 76·3 versus 75·5 per cent at 12 months, with no significant differences between groups. Micturition symptoms were less affected than sexual function and gradually improved to preoperative levels by 6 months. Adjusting for confounders, including radiotherapy, did not change these results. CONCLUSION Sexual dysfunction is common in patients with rectal cancer, and treatment (including surgery) increases the proportion of patients affected. A laparoscopic approach does not change this.

Abstract
Purpose
The Tisseel/Tissucol for mesh fixation in Lichtenstein hernia repair (TIMELI) study showed that mesh fixation with human fibrin sealant during inguinal hernia repair significantly reduced moderate–severe complications of pain 12 months post-operatively compared with sutures. Further analyses may assist surgeons by investigating predictors of post-surgical complications and identifying patients that may benefit from Tisseel/Tissucol intervention. Methods Univariate and multivariate analyses identified risk factors for combined pain, numbness and groin discomfort (PND) visual analogue scale (VAS) score 12 months post-operatively. Variables tested were: fixation method, age, employment status, physical activity, nerve handling, PND VAS score at pre-operative visit and 1 week post-operatively. The effect of fixation technique on separate PND outcomes 12 months post-surgery was also assessed. Analyses included the intention-to-treat (ITT) population and a subpopulation with pre-operative PND VAS > 30 mm. Results 316 patients were included in the ITT, with 130 patients in the subpopulation with pre-operative PND VAS > 30. Multivariate analysis identified mesh fixation with sutures, worsening pre-operative PND and worsening PND 1 week post-surgery as significant predictors of 12-month PND in the ITT population; mesh fixation with sutures was a significant predictor of 12-month PND in the pre-operative PND VAS > 30 subpopulation (p < 0.05). Mesh fixation with Tisseel/Tissucol resulted in significantly less numbness and a lower intensity of groin discomfort compared with sutures at 12 months; there was no difference in pain between the treatment groups. Conclusions Pre-operative discomfort may be an important predictor of post-operative pain, numbness and discomfort. Tisseel/Tissucol may improve long-term morbidity over conventional sutures in these patients.

Abstract
BACKGROUND AND PURPOSE Parallel imaging facilitates the acquisition of echo-planar images with a reduced TE, enabling the incorporation of an additional image at a later TE. Here we investigated the use of a parallel imaging-enhanced dual-echo EPI sequence to improve lesion conspicuity in diffusion-weighted imaging. MATERIALS AND METHODS Parallel imaging-enhanced dual-echo DWI data were acquired in 50 consecutive patients suspected of stroke at 1.5T. The dual-echo acquisition included 2 EPI for 1 diffusion-preparation period (echo 1 [TE = 48 ms] and echo 2 [TE = 105 ms]). Three neuroradiologists independently reviewed the 2 echoes by using the routine DWI of our institution as a reference. Images were graded on lesion conspicuity, diagnostic confidence, and image quality. The apparent diffusion coefficient map from echo 1 was used to validate the presence of acute infarction. Relaxivity maps calculated from the 2 echoes were evaluated for potential complementary information. RESULTS Echo 1 and 2 DWIs were rated as better than the reference DWI. While echo 1 had better image quality overall, echo 2 was unanimously favored over both echo 1 and the reference DWI for its high sensitivity in detecting acute infarcts. CONCLUSIONS Parallel imaging-enhanced dual-echo diffusion-weighted EPI is a useful method for evaluating lesions with reduced diffusivity. The long TE of echo 2 produced DWIs that exhibited superior lesion conspicuity compared with images acquired at a shorter TE. Echo 1 provided higher SNR ADC maps for specificity to acute infarction. The relaxivity maps may serve to complement information regarding blood products and mineralization.

Abstract
BACKGROUND There are no randomized studies that compare outcomes after single-incision (SLC) and conventional multi-incision (MLC) laparoscopic cholecystectomy under an optimized perioperative analgesic regimen. METHODS This patient- and assessor-blinded randomized three-centre clinical trial compared SLC and MLC in women admitted electively with cholecystolithiasis. Outcomes were registered on the day of operation (day 0), on postoperative days 1, 2, 3 and 30, and 12 months after surgery. Blinding of the patients was maintained until day 3. The primary endpoint was pain on movement measured on a visual analogue scale, reported repeatedly by the patient until day 3. RESULTS The intention-to-treat population comprised 59 patients in the SLC and 58 in the MLC group. There was no significant difference between the groups with regard to any of the pain-related outcomes, on-demand administration of opioids or general discomfort. Median duration of surgery was 32·5 min longer in the SLC group (P < 0·001). SLC was associated with a reduced incidence of vomiting on day 0 (7 versus 22 per cent; P = 0·019). The incidences of wound-related problems were comparable. One patient in the SLC group experienced a biliary leak requiring endoscopic retrograde cholangiopancreatography. The rates of incisional hernia at 12-month follow-up were 2 per cent in both groups. Cosmetic rating was significantly improved after SLC at 1 and 12 months (P < 0·001). CONCLUSION SLC did not significantly diminish early pain in a setting with optimized perioperative analgesic patient care. SLC may reduce postoperative vomiting.

Abstract
Objective: Ischaemia-reperfusion (IR) injury is partly caused by the release of reactive oxygen species and cytokines and may result in remote organ injury. Surgical patients are exposed to surgical stress and anaesthesia, both of which can influence the IR response. An IR model without these interfering factors of surgery is, therefore, useful to test the potential of antioxidant and cytokine-modulatory treatments. The aim of this study was to characterize a human ischaemia-reperfusion model with respect to oxidative and inflammatory biomarkers. Materials and methods: Ten male volunteers were exposed to 20 minutes of lower limb ischaemia. Muscle biopsies and blood samples were taken at baseline and 5, 15, 30, 60 and 90 minutes after tourniquet release and analysed for malondialdehyde (MDA), ascorbic acid, dehydroascorbic acid, tumor necrosis factor (TNF)-α, interleukin (IL)-1β, IL-1 receptor antagonist (IL-1Ra), IL-6, IL-10, TNF-receptor (TNF-R)I, TNF-RII and YKL-40. Results: We found no significant increase in MDA in the muscle biopsies after reperfusion. Plasma levels of oxidative and pro- and anti-inflammatory parameters showed no significant differences between baseline and after reperfusion at any sampling time. Conclusion: Twenty minutes of lower limb ischaemia does not result in an ischaemia-reperfusion injury in healthy volunteers, measurable by oxidative and pro- and anti-inflammatory biomarkers in muscle biopsies and in the systemic circulation.

Abstract
BACKGROUND Emergency major gastrointestinal (GI) surgery carries a considerable risk of mortality and postoperative complications. Effective management of complications and appropriate organization of postoperative care may improve outcome. The importance of the latter is poorly described in emergency GI surgical patients. We aimed to present mortality data and evaluate the postoperative care pathways used after emergency GI surgery. METHODS A population-based cohort study with prospectively collected data from six Capital Region hospitals in Denmark. We included 2904 patients undergoing major GI laparotomy or laparoscopy surgery between January 1, 2009, and December 31, 2010. The primary outcome measure was 30 day mortality. RESULTS A total of 538 patients [18.5%, 95% confidence interval (CI): 17.1-19.9] died within 30 days of surgery. In all, 84.2% of the patients were treated after operation in the standard ward, with a 30 day mortality of 14.3%, and 4.8% were admitted to the intensive care unit (ICU) after a median stay of 2 days (inter-quartile range: 1-6). When compared with 'admission to standard ward', 'admission to standard ward before ICU admission' and 'ICU admission after surgery' were independently associated with 30 day mortality; odds ratio 5.45 (95% CI: 3.48-8.56) and 3.27 (95% CI: 2.45-4.36), respectively. CONCLUSIONS Mortality in emergency major GI surgical patients remains high. Failure to allocate patients to the appropriate level of care immediately after surgery may contribute to the high postoperative mortality. Future research should focus on improving risk stratification and evaluating the effect of different postoperative care pathways in emergency GI surgery.

Abstract
BACKGROUND AND PURPOSE 2D gradient-echo imaging is sensitive to T2* lesions (hemorrhages, mineralization, and vascular lesions), and susceptibility-weighted imaging is even more sensitive, but at the cost of additional scan time (SWI: 5-10 minutes; 2D gradient-echo: 2 minutes). The long acquisition time of SWI may pose challenges in motion-prone patients. We hypothesized that 2D SWI/phase unwrapped images processed from 2D gradient-echo imaging could improve T2* lesion detection. MATERIALS AND METHODS 2D gradient-echo brain images of 50 consecutive pediatric patients (mean age, 8 years) acquired at 3T were retrospectively processed to generate 2D SWI/phase unwrapped images. The 2D gradient-echo and 2D SWI/phase unwrapped images were compared for various imaging parameters and were scored in a blinded fashion. RESULTS Of 50 patients, 2D gradient-echo imaging detected T2* lesions in 29 patients and had normal findings in 21 patients. 2D SWI was more sensitive than standard 2D gradient-echo imaging in detecting T2* lesions (P < .0001). 2D SWI/phase unwrapped imaging also improved delineation of normal venous structures and nonpathologic calcifications and helped distinguish calcifications from hemorrhage. A few pitfalls of 2D SWI/phase unwrapped imaging were noted, including worsened motion and dental artifacts and challenges in detecting T2* lesions adjacent to calvaria or robust deoxygenated veins. CONCLUSIONS 2D SWI and associated phase unwrapped images processed from standard 2D gradient-echo images were more sensitive in detecting T2* lesions and delineating normal venous structures and nonpathologic mineralization, and they also helped distinguish calcification at no additional scan time. SWI processing of 2D gradient-echo images may be a useful adjunct in cases in which longer scan times of 3D SWI are difficult to implement.

Abstract
BACKGROUND/AIM Research has shown that chemoprevention may be effective against the development of lung cancer. The purpose of the present study was to evaluate the effect of oral chemoprevention in a mouse model of tobacco carcinogen-induced lung tumor. MATERIALS AND METHODS A total of 60 A/J mice were randomized to a normal diet, a diet with low calcium, or a chemoprevention diet with acetylsalicylic acid, 1-α 25(0H)2-vitamin D3 and calcium. In addition to the diet, mice received carcinogens by oral gavage for ten weeks. RESULTS The chemoprevention diet significantly reduced the number of animals with tumors [1 vs. 13, (p<0.001)] and the median number (range) of tumors [0 (0-1) vs. 1 (0-4), (p<0.001)] compared to controls. No signs of toxicity in relation to the diets were observed. CONCLUSION The chemoprevention diet had a protective effect against tumor development in the mouse lungs.
