Abstract
PURPOSE Quality of life (QoL) is temporarily compromised after pancreatic surgery, but no evidence for a negative impact of postoperative complications on QoL has been provided thus far. Delayed gastric emptying (DGE) is one of the most common complications after pancreatic surgery and is associated with a high level of distress. Therefore, the aim of this study was to analyse the influence of DGE on QoL. METHODS This single-centre retrospective study analysed QoL after partial duodenopancreatectomy (PD) via the European Organization for Research and Treatment of Cancer core questionnaire (QLQ-C30). The QoL of patients with and without postoperative DGE was compared. RESULTS Between 2010 and 2022, 251 patients were included, 85 of whom developed DGE (34%). Within the first postoperative year, compared to patients without DGE, those with DGE had a significantly reduced QoL, by 9.0 points (95% CI: -13.0 to -5.1, p < 0.001). Specifically, physical and psychosocial functioning (p = 0.020) decreased significantly, and patients with DGE suffered significantly more from fatigue (p = 0.010) and appetite loss (p = 0.017) than patients without DGE. After the first postoperative year, there were no significant differences in QoL or symptom scores between patients with DGE and those without DGE. CONCLUSION Patients who developed DGE reported a significantly reduced QoL and reduced physical and psychosocial functioning within the first year after partial pancreatoduodenectomy compared to patients without DGE.

Abstract
INTRODUCTION Marginal ulcers are an acid-related complication of laparoscopic Roux-en-Y gastric bypass. Few cases of acute perforation have been described, and there are few reports on viable surgical management. This case report demonstrates a two-step surgical procedure for treating a perforated late marginal ulcer in a patient with sepsis. PRESENTATION OF CASE A 39-year-old smoker presented to the emergency department six years after undergoing a Roux-en-Y gastric bypass. Diagnostic findings revealed ascites and changes in intestinal calibre, indicating the need for surgery. Intraoperatively, a perforated marginal ulcer covered by the liver was observed. Given the extent of the perforation and the patient's increased instability, discontinuity resection was performed. After stabilisation and improvement in the nutritional status, the gastrojejunostomy was restored nine weeks later. DISCUSSION Treatment of Marginal ulcers is controversial, with no clear guidelines. However, severe complications require endoscopic or surgical treatment. The literature considers three main surgical treatment options for perforated marginal ulcers: surgical repair, surgical anastomotic revision, and gastric bypass reversal. Complicated situations, significant intraoperative findings, and unstable patients require tailored approaches. CONCLUSION A two-step procedure with discontinuity resection for damage control surgery, patient stabilisation, and improvement of nutritional status, followed by elective continuity restoration with a new gastrojejunostomy, is considered feasible in critically ill patients.

Abstract
BACKGROUND Pancreatic surgery remains associated with high morbidity rates. Although postoperative mortality appears to have improved with specialization, the outcomes reported in the literature reflect the activity of highly specialized centres. The aim of this study was to evaluate the outcomes following pancreatic surgery worldwide. METHODS This was an international, prospective, multicentre, cross-sectional snapshot study of consecutive patients undergoing pancreatic operations worldwide in a 3-month interval in 2021. The primary outcome was postoperative mortality within 90 days of surgery. Multivariable logistic regression was used to explore relationships with Human Development Index (HDI) and other parameters. RESULTS A total of 4223 patients from 67 countries were analysed. A complication of any severity was detected in 68.7 per cent of patients (2901 of 4223). Major complication rates (Clavien-Dindo grade at least IIIa) were 24, 18, and 27 per cent, and mortality rates were 10, 5, and 5 per cent in low-to-middle-, high-, and very high-HDI countries respectively. The 90-day postoperative mortality rate was 5.4 per cent (229 of 4223) overall, but was significantly higher in the low-to-middle-HDI group (adjusted OR 2.88, 95 per cent c.i. 1.80 to 4.48). The overall failure-to-rescue rate was 21 per cent; however, it was 41 per cent in low-to-middle- compared with 19 per cent in very high-HDI countries. CONCLUSION Excess mortality in low-to-middle-HDI countries could be attributable to failure to rescue of patients from severe complications. The authors call for a collaborative response from international and regional associations of pancreatic surgeons to address management related to death from postoperative complications to tackle the global disparities in the outcomes of pancreatic surgery (NCT04652271; ISRCTN95140761).

Abstract
INTRODUCTION Randomised controlled trials (RCTs) continue to provide the best evidence for treatment options, but the quality of reporting in RCTs and the completeness rate of reporting of surgical outcomes and complication data vary widely. The aim of this study was to measure the quality of reporting of the surgical outcome and complication data in RCTs of rectal cancer treatment and whether this quality has changed over time. METHODS Eligible articles with the keywords ("rectal cancer" OR "rectal carcinoma") AND ("radiation" OR "radiotherapy") that were RCTs and published in the English, German, Polish, or Italian language were identified by reviewing all abstracts published from 1982 through 2022. Two authors independently screened and analysed all studies. The quality of the surgical outcome and complication data was assessed based on fourteen criteria, and the quality of RCTs was evaluated based on a modified Jadad scale. The primary outcome was the quality of reporting in RCTs and the completeness rate of reporting of surgical results and complication data. RESULTS A total of 340 articles reporting multimodal therapy outcomes for 143,576 rectal cancer patients were analysed. A total of 7 articles (2%) met all 14 reporting criteria, 13 met 13 criteria, 27 met from 11 to 12 criteria, 36 met from 9 to 10 criteria, 76 met from 7 to 8 criteria, and most articles met fewer than 7 criteria (mean 5.5 criteria). Commonly underreported criteria included complication severity (15% of articles), macroscopic integrity of mesorectal excision (17% of articles), length of stay (18% of articles), number of lymph nodes (21% of articles), distance between the tumour and circumferential resection margin (CRM) (26% of articles), surgical radicality according to the site of the primary tumour (R0 vs. R1 + R2) (29% of articles), and CRM status (38% of articles). CONCLUSION Inconsistent surgical outcome and complication data reporting in multimodal rectal cancer treatment RCTs is standard. Standardised reporting of clinical and oncological outcomes should be established to facilitate comparing studies and results of related research topics.

Abstract
BACKGROUND Groove pancreatitis is a focal form of chronic pancreatitis affecting the area of the paraduodenal groove. The aim of this systematic review was to assess the clinical presentation, diagnosis and treatment of patients with groove pancreatitis. METHODS Medical literature databases (Embase, Medline via PubMed and Cochrane Central Register of Controlled Trials) were systematically searched for data recorded between 1 January 1990 and 31 August 2022 regarding patient characteristics, diagnosis, surgical treatment and outcomes. The following inclusion criteria were applied: RCTs, observational studies (cohort and case-control studies) and case studies with >3 cases including patients with groove pancreatitis undergoing medical, endoscopic or surgical treatment with available clinical and diagnostic data. Fisher's exact test for binary data and Mann-Whitney U test or Student t-test for continuous data were adopted for statistical analysis. RESULTS Of 649 studies, 44 were included, involving reports on 1404 patients with a mean age of 49 years. In 41 of the 44 studies in which patient gender was described, 86 per cent (N = 1023) of patients were male. Information on the risk factors of alcohol and nicotine was available in 37 and 23 studies, respectively. Seventy-nine per cent (N = 886) of patients had a history of excessive alcohol consumption and 83 per cent (N = 595) were smokers. Information on clinical symptoms was available in 37 of the 44 included studies and 78.5 per cent (N = 870) presented with abdominal pain. Some 27 studies comprising 920 groove pancreatitis patients were treatment oriented. Seventy-four per cent (N = 682) of patients were treated conservatively, 26.4 per cent (N = 134) underwent endoscopic treatment and 54.7 per cent (N = 503) required surgery. There was complete relief of symptoms in 35.6 per cent (N = 243) after conservative treatment, 55.2 per cent (N = 74) after endoscopic treatment and 69.6 per cent (N = 350) after surgical treatment. The median follow-up time was 42 months (range, 1-161 months). CONCLUSION Groove pancreatitis shows on imaging a typical triad: cystic lesions in the pancreatic duct or duodenal wall, calcifications, and thickenings of the duodenal wall. Surgery appears to be the most effective treatment modality.

Abstract
BACKGROUND Postoperative ileus is common after gastrointestinal surgery. This network meta-analysis aimed to compare the effectiveness of gum chewing and coffee and caffeine intake on ileus-related outcomes. METHODS A systematic literature review was performed to identify randomized controlled trials (RCTs) comparing noninvasive treatments for ileus after gastrointestinal surgery. The main analyses included random effects network meta-analyses using frequentist methods with simultaneous direct and indirect comparisons of time to first flatus, time to first defecation, and length of stay. Bayesian network meta-analysis using Markov chains was also used. RESULTS A total of 32 RCTs comparing 4999 patients were included in this network meta-analysis. Time to flatus was reduced by gum chewing (mean difference compared to control (MD): -11 h, 95% confidence interval (95% CI) - 16 to - 5 h, P < 0.001). Time to defecation was reduced by gum chewing and coffee, with MDs of -18 h (95% CI - 23 to - 13 h, P < 0.001) and -13 h (95% CI - 24 to - 1 h, P < 0.001), respectively. Length of stay was reduced by coffee and gum chewing with MDs of - 1.5 days (95% CI: - 2.5 to - 0.6 days, P < 0.001) and - 0.9 days (95% CI: - 1.3 to - 0.4 days, P < 0.001), respectively. CONCLUSION Coffee and gum chewing were proven to be effective noninvasive approaches for shortening the postoperative length of hospital stay and time to first defecation, especially in open gastrointestinal surgery; thus these actions should be recommended after gastrointestinal surgery.

Abstract
INTRODUCTION Over the past two decades, cytoreductive surgery and HIPEC has improved outcomes for selected patients with peritoneal metastasis from various origins. This is a cross-sectional study with descriptive analyses of HIPEC trials registered on ClinicalTrials.gov. This study aimed to characterize clinical trials on HIPEC registered on ClinicalTrials.gov with the primary objective of identifying a trial focus and to examine whether trial results were published. METHODS The search included trials registered from 1 January 2001 to 14 March 2022. We examined the associations of exposure variables and other trial features with two primary outcomes: therapeutic focus and results reporting. RESULTS In total, 234 clinical trials were identified; 26 (11%) were already published, and 15 (6%) trials have reported their results but have not been published as full papers. Among ongoing nonpublished trials, 81 (39%) were randomized, 30 (14%) were blinded, n = 39 (20%) were later phase trials (i.e., phases 3 and 4), n = 152 (73%) were from a single institution, and 91 (44%) had parallel groups. Most of the trials were recruiting at the time of this analysis (75, 36%), and 39 (20%) were completed but had yet to publish results. In total, 68% of the trials focused on treatment strategies, and 53% investigated the oncological outcome. The most studied neoplasms for HIPEC trials were peritoneally metastasized colorectal cancer (32%), gastric cancer (29%), and ovarian cancer (26%). Twenty different drugs were analyzed in these clinical trials. CONCLUSIONS Many study results are awaited from ongoing HIPEC trials. Most HIPEC trials focused on gastric, colorectal, or ovarian cancer. Many clinical trials were identified involving multiple entities and chemotherapeutic agents.

Abstract
BACKGROUND The cause, extent, and role of muscle edema for muscle degeneration are unknown and not considered in the current literature. In vivo experiments were designed to prove muscle edema formation in the early period in a sheep model of acute rotator cuff tears. HYPOTHESIS Muscle edema occurs after tendon release with or without additional stretching trauma and may be associated with muscle retraction and subsequent muscle degeneration. STUDY DESIGN Controlled laboratory study. METHODS A sheep model with acute release of the infraspinatus tendon was used. An osteotomy of the greater tuberosity, including the insertion of the infraspinatus tendon, was performed in 14 sheep. To demonstrate presence of edema, magnetic resonance imaging scans were performed at 0, 2, and 4 weeks using T1-weighted, T2-weighted, proton density-weighted, and Dixon sequences. Excisional biopsy specimens were taken at 0, 3, and 4 weeks (histological results will be reported in a later publication). Two injury models were created: a nontrauma group that consisted of muscle release alone and a trauma group that included additional standardized traction to the musculotendinous unit. Evaluation of T1- and T2-weighted images included calculation of pennation angle, muscle fiber length, signal intensity (edema), and muscle volume. Muscle wet weight and volume were measured at sacrifice. RESULTS Edema formation was shown in all sheep and slightly more pronounced in the trauma group, where muscle intensity increased significantly between time point 0 (200 Grey Value (GV)) and weeks 2, 3, and 4 (300 GV). Edema formation started early after tendon release with a plateau between 3 and 4 weeks. Deterioration of muscle fiber bundles began also after tendon release with a peak at 4 weeks. Muscle volume decreased steadily over time. CONCLUSION Muscle edema appeared early after rotator cuff tendon release, was more pronounced in the trauma group, and reached a plateau after 3 to 4 weeks. Muscle fatty content decreased within the short period of 4 weeks owing to a dilution effect. Muscle edema seems to be an essential factor in cuff tears and subsequent muscle retraction and degeneration. CLINICAL RELEVANCE This study demonstrates a new type of muscle edema of retraction and describes the characteristics of edema associated with a retracted rotator cuff tear.

Abstract
BACKGROUND Coffee has been suggested to help postoperative gastrointestinal motility but the mechanism is not known. This trial assessed whether caffeine shortened time to bowel activity after laparoscopic colectomy. METHODS This was a single-centre, randomized, double-blinded, placebo-controlled superiority trial (October 2015 to August 2020). Patients aged at least 18 years undergoing elective laparoscopic colectomy were assigned randomly to receive 100 mg or 200 mg caffeine, or a placebo (250 mg corn starch) three times a day orally. The primary endpoint was the time to first bowel movement. Secondary endpoints included colonic transit time, time to tolerance of solid food, duration of hospital stay, and perioperative morbidity. RESULTS Sixty patients were assigned randomly to either the 200-mg caffeine group (20 patients), the 100-mg caffeine group (20) or the placebo group (20). In the intention-to-treat analysis, the mean(s.d.) time to first bowel movement was 67.9(19.2) h in the 200-mg caffeine group, 68.2(32.2) h in the 100-mg caffeine group, and 67.3(22.7) h in the placebo group (P = 0.887). The per-protocol analysis and measurement of colonic transit time confirmed no measurable difference with caffeine. CONCLUSION Caffeine was not associated with reduced time to first bowel movement.

Abstract
Abstract
Objective
Avoidance of prolonged postoperative bowel paralysis after colorectal surgery is of major importance due to its significant clinical implications. Postoperative caffeine consumption appears to be a promising strategy. The aim of this study was to assess whether postoperative oral caffeine intake shortens bowel hypomotility after elective laparoscopic colorectal surgery.
Methods
This was a single-center, randomized, double-blinded, placebo-controlled superiority trial conducted from October 1st, 2015 to August 10th, 2020. Patients aged >=18 years with malignant or benign disease undergoing elective laparoscopic colectomy were included and assigned randomly before surgery to receive 3x daily either 100 mg caffeine or 200 mg caffeine or 250 mg corn starch (placebo) after the procedure. Substances were served in indistinguishable capsules three times daily before the meals. The primary endpoint was time to first bowel movement, measured from the time of wound closure to the patient's first defecation. Secondary endpoints included colonic transit time, time to tolerance of solid food, length of hospital stay and perioperative morbidity.
Results
A total of 60 patients were randomized, 20 to each group. Twenty-seven patients followed the protocol and were included in the per-protocol (PP) analysis. Baseline characteristics were similarly distributed among the groups. In intention-to-treat analysis, the time to first bowel movement in the caffeine 200 mg group was 67.9 h (standard deviation [SD] 19.2), in the caffeine 100 mg group 68.2 h (SD 32.2) and in the placebo group 67.3 h (SD 22.7) (p=0.887). PP analysis and measurement of colonic transit time (41.8 h [SD 21.7] in the caffeine 200 mg group, 34.2 h [SD 22.9] in the caffeine 100 mg group and 46.3 h [SD 20.6] in the placebo group, p=0.317) confirmed non-significant differences. The time to tolerance of solid food, length of hospital stay and postoperative morbidity were comparable among the three groups and no deaths or related serious adverse events were observed during the study.
Conclusion
Although caffeine intake after laparoscopic colorectal surgery is safe, its administration was not associated with a shortened time to first bowel movement in contrast to previous studies. Thus, other ingredients of coffee might be responsible for the intestinal stimulatory effect previously described.

Abstract
BACKGROUND Complete and correct documentation of diagnosis and procedures is essential for adequate health provider reimbursement in diagnosis-related group (DRG) systems. The objective of this study was to investigate whether daily monitoring and semiautomated proposal optimization of DRG coding (precoding) is associated with higher reimbursement per hospitalization day. MATERIALS AND METHODS This parallel-group, unblinded, randomized clinical trial randomized patients 1:1 into intervention (precoding) and control groups. Between June 12 and December 6, 2019 all hospitalized patients (1566 cases) undergoing elective or emergency surgery at the department of surgery in a Swiss hospital were eligible for this study. By random sample selection, cases were assigned to the intervention (precoding) and control groups. The primary outcome was the total reimbursement, divided by the length of stay. RESULTS Of the 1205 randomized cases, 1200 (precoding group: 602) remained for intention-to-treat, and 1131 (precoding group: 564) for per-protocol analysis. Precoding increased reimbursement per hospitalization day by 6.5% (160 US dollars; 95% confidence interval 31 to 289; P = 0.015). In a regression analysis patients hospitalized 7 days or longer, precoding increased reimbursement per day by 10.0% (246 US dollars; 95% confidence interval -12 to 504; P = 0.021). More secondary diagnoses (mean [SD]: 5.16 [5.60] vs 4.39 [5.34]; 0.77; 95% confidence interval 0.15 to 1.39; P = 0.015) and nonsurgical postoperative complications (mean [SD]: 0.68 [1.45] vs 0.45 [1.12]; 0.23; 95% confidence interval 0.08 to 0.38; P = 0.002) were documented by precoding. No associated was observed regarding the length of stay, total reimbursement, or case mix index. The mean (SD) precoding time effort was 37 (27) minutes per case. CONCLUSION Physician-led precoding increases DRG-based reimbursement. Precoding is time consuming and should be focused on cases with a longer hospital stay to increase efficiency.

Abstract
INTRODUCTION Pressurized intraperitoneal aerosol chemotherapy (PIPAC) is a treatment option for patients with peritoneal metastases. We evaluated the current status of ongoing prospective clinical trials investigating PIPAC to provide an overview and predict trends in this field. METHODS All 367,494 records of clinical trials registered at ClinicalTrials.gov were searched for trials dealing with PIPAC. Active or unpublished trials were further analyzed. RESULTS In total, 22 clinical trials were identified and selected for further analyses. Most trials had a single-arm design and were phase I or II. No phase III trials were registered. Academic centers were recorded as primary sponsors in the majority of trials (63.6%). Every year, between 2 and 5 new trials were initiated. In 17 trials (81.8%), PIPAC was used in a palliative setting only, 2 trials performed PIPAC in a neoadjuvant setting, and 2 trials performed PIPAC in an adjuvant setting. Six different drugs (doxorubicin, cisplatin, oxaliplatin, nab-paclitaxel, 5-fluorouracil, and docetaxel) were used in these clinical trials. Most trials investigated the efficacy (n = 15) or safety (n = 7) of PIPAC therapies. CONCLUSIONS The results of ongoing clinical trials will bring specific information on indications for PIPAC as well as the impact of PIPAC on quality of life and overall survival.

Abstract
BACKGROUND Postoperative aspiration pneumonia is a feared complication contributing significantly to postoperative morbidity and mortality. Over decades, there has been little progress in reducing incidence and mortality of postoperative aspiration pneumonia. Here, we assessed risk factors for postoperative aspiration pneumonia in general and abdominal surgery patients. METHODS Patients undergoing surgery between January 2012 and December 2018 were included in this exact matched and weighted case-control study. Data from a prospectively acquired clinical database were retrospectively analyzed. RESULTS Among 23,647 patients undergoing 32,901 operations, 144 (0.44%, 95% Confidence Interval: 0.37%-0.52%) cases of postoperative aspiration pneumonia were identified. Ninety-day mortality was 27.8% (n = 40). Major risk factors for postoperative aspiration pneumonia were emergency surgery in patients with prolonged preoperative fasting (>6 hours; odds ratio: 3.25, 95% confidence interval: 1.46-7.26; P < .001), older age with increasing risk in octogenarians compared to seniors (65-80 years: n = 69; odds ratio 5.23, 95% confidence interval: 2.18-12.51; >80 years: n = 50; odds ratio 13.72, 95% confidence interval: 4.94-38.09; P < .001), American Society of Anesthesiologists scores >II (American Society of Anesthesiologists III: n = 90; odds ratio 3.38, 95% confidence interval: 1.08-16.01; American Society of Anesthesiologists IV/V: n = 18; odds ratio 5.20, 95% confidence interval: 1.48-27.61; P < .001), and body mass index <18 kg/m2 (n = 9; odds ratio: 2.53; 95% confidence interval: 1.04-6.11; P = .029). Laparoscopies (odds ratio 0.45, 95% confidence interval: 0.23-0.88; <0.001) and female sex were associated with a decreased risk for postoperative aspiration pneumonia (odds ratio 0.40, 95% confidence interval: 0.23-0.69; P < .001). CONCLUSION Preventive measures to reduce postoperative aspiration pneumonia should focus on older patients with American Society of Anesthesiologists scores ≥III undergoing open surgery. Cachectic patients and patients undergoing emergency surgery with prolonged preoperative fasting require increased attention. Laparoscopy was associated with a lower risk for postoperative aspiration pneumonia and should be preferred whenever appropriate.

Abstract
Hiatal herniations are most commonly diagnosed during work-up for gastroesophageal reflux disease. Here, we present a patient with retrosternal pain for whom the computed tomography scan showed a lipomatous formation in the lower posterior mediastinum, and further examination indicated the origin to be paraesophageal herniation (PEH) of the greater omentum. This was confirmed by laparoscopy, the herniated part of the greater omentum was repositioned and the hiatal hernia was repaired. During recovery the patient complained of dysphagia, a common and transient postoperative occurrence, but which later proved to be a mechanical obstruction caused by a bolus. This case raises awareness of potential differential diagnoses pre- and postoperatively in conjunction with PEH, and the management of such differential diagnoses is discussed.

Abstract
BACKGROUND The COVID-19 pandemic has rapidly spread worldwide. As it is a novel disease, we have less experience in its possible appearances. Predominantly affecting the respiratory tract, about 20-43% patients also present with extrapulmonary manifestations such as coagulation disorders with thrombotic angiopathy. CASE PRESENTATION In our institution, a patient presented to the emergency department with acute abdominal pain which was caused by portal vein thrombosis. As a COVID-19 nasopharyngeal antigen swab few days earlier was negative, we performed several tests to find out its etiology. After all tests were inconclusive and the patient suffered flu-like symptoms 2 weeks before, we repeated COVID-19 molecular testing and received a positive test result. The patient was treated symptomatically and received therapeutic anticoagulation. CONCLUSION A COVID-19 infection can also be present without typical pulmonary symptoms. In patients with severe abdominal pain and new diagnosed portal vein thrombosis, it is important to think of a COVID-19 infection. Also, the reliability of antigen nasopharyngeal swab should be considered critically, especially if performed wrongly. We recommended to perform molecular tests when in doubt. After the diagnosis of portal vein thrombosis, immediate anticoagulation is recommended to reduce the risk of further complications like intestinal infarction.

Abstract
BACKGROUND Multimodal treatment, including systemic treatment and surgery, improved the prognosis of peritoneal metastasis (PM). Despite all efforts, recurrence rates remain high, and little data are available about clinical behavior or molecular patterns of PM in comparison to hematogenous metastasis. Here, we aimed to analyze recurrence patterns after multimodal treatment for PM from colorectal cancer. METHODS Patients with colorectal PM undergoing multimodal treatment including systemic chemotherapy and cytoreductive surgery plus hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) between 2005 and 2017 at 4 centers were analyzed retrospectively. RESULTS A total of 505 patients undergoing CRS/HIPEC were analyzed. Of the patients, 82.1% received preoperative chemotherapy. Median peritoneal cancer index was 6 (interquartile range = 3-11). Median disease-free and overall survival was 12 (95% confidence interval [CI] = 11 to 14) months and 51 (95% CI = 43 to 62) months, respectively. Disease recurred in 361 (71.5%) patients, presenting as isolated peritoneal recurrence in 24.6%, isolated hematogenous recurrence in 28.3%, and mixed recurrence in 13.9% of patients. Recurrence to the peritoneum was associated with an impaired time from recurrence to death of 21 (95% CI = 18 to 31) months for isolated peritoneal and 22 (95% CI = 16 to 30) months for mixed recurrence, compared with 43 (95% CI = 31 to >121) months for hematogenous recurrence (hazard ratio [HR] = 1.79, 95% CI = 1.27 to 2.53; P = .001; and HR = 2.44, 95% CI = 1.61 to 3.79; P < .001). On multiple logistic regression analysis, RAS mutational status (odds ratio [OR] = 2.42, 95% CI = 1.11 to 5.47; P = .03) and positive nodal stage of the primary (OR = 3.88, 95% CI = 1.40 to 11.86; P = .01) were identified as predictive factors for peritoneal recurrence. CONCLUSIONS This study highlights the heterogeneity of peritoneal metastasis in patients with colorectal cancer. Recurrent peritoneal metastasis after radical treatment represents a more aggressive subset of metastatic colorectal cancer.

Abstract
OBJECTIVES To assess the individual treatment strategies among international experts in peritoneal carcinosis, specifically their decision-making in the process of patient selection for hyperthermic intraperitoneal chemotherapy (HIPEC) in women suffering from ovarian cancer, to identify relevant decision-making criteria, and to quantify the level of consensus for or against HIPEC. METHODS The members of the executive committee of the Peritoneal Surface Oncology Group International (PSOGI) were asked to describe the clinical conditions under which they would recommend HIPEC in patients with ovarian cancer and to describe any disease or patient characteristics relevant to their decision. All answers were then merged and converted into decision trees. The decision trees were then analyzed by applying the objective consensus methodology. RESULTS Nine experts in surgical oncology provided information on their multidisciplinary treatment strategy including HIPEC for patients with advanced ovarian cancer. Three of the total of 12 experts did not perform HIPEC. Five criteria relevant to the decision on whether HIPEC is performed were applied. In patients with resectable disease, a peritoneal cancer index (PCI) <21, and epithelial ovarian cancer without distant metastasis, consent was received by 75% to perform HIPEC for women suffering from recurrent disease. Furthermore, in the primary disease setting, consent was received by 67% to perform HIPEC according to the same criteria. DISCUSSION AND CONCLUSION Among surgical oncology experts in peritoneal surface malignancy and HIPEC, HIPEC plays an important role in primary and recurrent ovarian cancer, and the PCI is the most important criterion in this decision.

Abstract
The current gold standard technique for treatment of anterior cruciate ligament (ACL) injury is reconstruction with autograft. These treatments have a relatively high failure and re-tear rate. To overcome this, tissue engineering and additive manufacturing are being used to explore the potential of 3D scaffolds as autograft substitutes. However, mechanically optimal polymers for this have yet to be identified. Here, we use 3D printing technology and various materials with the aim of fabricating constructs better matching the mechanical properties of the native ACL. A fused deposition modeling (FDM) 3D printer was used to microfabricate dog bone-shaped specimens from six different polymers—PLA, PETG, Lay FOMM 60, NinjaFlex, NinjaFlex-SemiFlex, and FlexiFil—at three different raster angles. The tensile mechanical properties of these polymers were determined from stress–strain curves. Our results indicate that no single material came close enough to successfully match reported mechanical properties of the native ACL. However, PLA and PETG had similar ultimate tensile strengths. Lay FOMM 60 displayed a percentage strain at failure similar to reported values for native ACL. Furthermore, raster angle had a significant impact on some mechanical properties for all of the materials except for FlexiFil. We therefore conclude that while none of these materials alone is optimal for mimicking ACL mechanical properties, there may be potential for creating a 3D-printed composite constructs to match ACL mechanical properties. Further investigations involving co-printing of stiff and elastomeric materials must be explored.

Abstract
Indeterminate dendritic cell tumor (IDCT) is an extremely rare hematologic neoplastic disorder with proliferation of indeterminate dendritic cells. In the vast majority of cases, IDCTs are restricted to the skin or lymph nodes. To our knowledge, we report the first case of IDCT in the pancreas. Due to the rarity of extracutaneous IDCT, guidelines or treatment recommendations addressing their management are missing. We performed a review of literature to compare our experience to the management of other extracutaneous IDCT. Histopathological examination confirms the diagnosis of IDCT in electron microscopy and/or immunohistochemistry. Specific features are the lack of Birbeck granules and the nonreaction to Langerin antibodies. Concerning the aftercare of extracutaneous IDCT, we recommend a dermatological examination to rule out an additional cutaneous manifestation as well as annual blood examinations due to the association between IDCT and hematologic malignancies.

Abstract
BACKGROUND Colorectal cancer (CRC) treatment for patients with peritoneal metastases is complex. The use of cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) has continued to be debated. The aim of the present study was to assess the consensus among international experts for decision-making regarding the use of CRS and HIPEC for patients with CRC. MATERIALS AND METHODS Of 15 experts invited, 12 had provided their decision algorithms for CRS and HIPEC for patients with, or at high risk of, peritoneal metastases from CRC. Using the objective consensus method, the results were transformed into decision trees to provide information on the consensus and discordance. RESULTS Only 1 scenario was found for which the consensus on performing HIPEC had reached 100%. The scenario was the treatment of young patients with complete cytoreduction and a peritoneal carcinomatosis index (PCI) of < 16 in the presence of certain risk factors. Five major decision criteria were identified: age, PCI, completeness of cytoreduction, extent of extraperitoneal metastases (EoMs), and, in the case of unverified EoMs, additional risk factors. Consensus was found regarding refraining from using HIPEC for older patients with a high PCI. The consensus further increased when addressing incomplete cytoreduction and an extensive extent of EoMs. CONCLUSION A definite consensus concerning the use of HIPEC was only determined for very selected scenarios. These findings can be used for general guidance; however, owing to the heterogeneity of each individual situation, the impracticality of presenting the information through decision trees, and the unclear future of the role of HIPEC in the adjuvant setting, a one-on-one transfer to daily clinical practice could not be achieved.

Abstract
Intestinal intussusception is a rare cause of intestinal obstruction; intestinal intussusception associated with endometriosis is very rare. The varied clinical presentations make the diagnosis demanding. In this article, we report the case of a young female patient with an intestinal obstruction due to intussusception. The successive histologic examination of the resected sample showed advanced endometriosis. This is a very rare entity with only a few similar cases reported in the literature.

Abstract
BACKGROUND The management of patients with colorectal cancer (CRC) with peritoneal metastases is challenging, and the roles of cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) are unclear and debated among experts. MATERIALS AND METHODS The experts of the Swiss Peritoneal Cancer Group were contacted and agreed to participate in this analysis. Experts from 9 centers in Switzerland provided their decision algorithms for CRS/HIPEC for patients with or at high risk for peritoneal metastases from CRC. Their responses were converted into decision trees on the basis of objective consensus methodology. The decision trees were used as a basis to identify consensus and discrepancies. RESULTS The final treatment algorithms included a total of 5 decision criteria (age, Peritoneal Cancer Index [PCI], extraperitoneal metastases, Peritoneal Surface Disease Severity Score, and various risk factors [RF]) and 2 treatment options (HIPEC, yes or no). HIPEC was never recommended for patients without peritoneal metastases in the absence of RF for peritoneal metastases. For patients with a PCI ≤15 without organ metastases, all centers recommended CRS/HIPEC. There was also a consensus not to perform CRS/HIPEC in elderly patients (80 years and older), those with a PCI >20, and those with unresectable metastases. For patients with a PCI = 16 to 20, there was no consensus. CONCLUSION Multiple decision criteria relevant to all participating centers were identified. Because patient selection for CRS/HIPEC remains difficult, uniform criteria for the term "high risk" for peritoneal metastases and systemic metastases are helpful. Future trials and guidelines should take these criteria into account.

Abstract
Background Infestations with scabies mites are a global burden affecting individuals of all ages, classes and ethnicities. As poor sanitation and overcrowding favor the transmission of this highly contagious disease, epidemic outbreaks are frequently observed among displaced persons and asylum seekers. Due to the growing influx of refugees during the last years, public health authorities in host countries are frequently confronted with the challenge to treat individuals with diagnosed or suspected scabies promptly and effectively to avoid further spreading of the infestation. This study aimed to establish a straightforward and efficient algorithm for rapid screening and treatment of large numbers of patients with confirmed or suspected scabies infestations. Methods Forty-eight individuals (58% males, mean age 22.4 yrs.) from Syria with suspected scabies infestation were allocated to 3 colour-coded groups: (1) no signs or symptoms of infestation, (2) itch only, and (3) itch and typical skin lesions. Patients were treated with a single (group 1) or two doses of oral ivermectin at an interval of 7 days (group 2), or with a combination of 2 doses of ivermectin plus 2 applications of permethrin ointment at an interval of 7 days (group 3). Follow-ups were performed 4 weeks after initial treatments. Results All individuals with signs and/or symptoms of infestation had improved skin lesion; in 10/11 (90.9%) lesion had completely resolved. All individuals with initial itch only (n = 32) reported improvement of its intensity or complete resolution. None of the patients of group 1 developed itch or skin lesions. The algorithm was reapplied in 4 individuals (8.3%) after 4 weeks and the outbreak was completely controlled after 8 weeks. Colour-coding ensured fast flow of information between health-care providers at the interfaces of the algorithm. Conclusions Our algorithm proved to be both highly efficient for treatment of large numbers of patients with suspected or diagnosed scabies infestation as well as for prevention of spreading of the disease. Hence, this algorithm is well suited for the management of scabies mass outbreaks.

Abstract
OBJECTIVE To provide an objective, quantitative morphometric description of the caudal cervical intervertebral disk (IVD) spaces of dogs. SAMPLE Vertebral specimens consisting of C4 through C7 from 5 medium-sized dogs. PROCEDURES CT images were obtained with the specimens positioned in neutral, flexion, extension, and lateral bending positions. Size and shape of the cranial and caudal end plates, angle between the end plates (IVD wedge angle), and craniocaudal distance (IVD width) between end plates for the 4 loading positions were measured and compared for the 3 segments (C4-5, C5-6, and C6-7). RESULTS End plate size and shape, IVD wedge angle, and IVD width were not significantly different among the 3 segments. Caudal cervical end plates were consistently larger than cranial cervical end plates. The IVD wedge angle ranged from -4.8° to 15.2°. Flexion induced a reduction in IVD width in the ventral portion of the IVD, whereas extension induced a decrease in width in the dorsal portion of the IVD. Central IVD width remained unchanged among the loading positions. CONCLUSIONS AND CLINICAL RELEVANCE Unique morphometric and dynamic characteristics of the caudal cervical IVD space of dogs were detected. These findings may help investigators when designing IVD prostheses for dogs with cervical spondylomyelopathy.

Abstract
The surgical standard of care for lumbar discectomy leaves the annulus fibrosus (AF) defect unrepaired, despite considerable risk for a recurrent herniation. Identification of a viable defect repair strategy has until now been elusive. The scope of this ex vivo biomechanical study was to evaluate crosslinking hydrogels as potentially promising AF defect sealants, and provide a baseline for their use in combination with collagen scaffolds that restore disc volume. This study directly compared genipin crosslinked fibrin hydrogel (FibGen) as a promising preclinical candidate against a clinically available adhesive composed of glutaraldehyde and albumin (BioGlue). Forty-two bovine coccygeal functional spine units (FSU) were randomly allocated into four groups, namely untreated (control, n = 12), repaired with either one of the tested hydrogels (BioGlue, n = 12; FibGen, n = 12), or FibGen used in combination with a collagen hydrogel scaffold (FibGen+Scaffold, n = 6). All specimens underwent a moderate mechanical testing protocol in intact, injured and repaired states. After completion of the moderate testing protocol, the samples underwent a ramp-to-failure test. Lumbar discectomy destabilized the FSU as quantified by increased torsional range of motion (28.0° (19.1, 45.1) vs. 41.39° (27.3, 84.9), p<0.001), torsional neutral zone (3.1° (1.2, 7.7) vs. 4.8° (2.1, 12.1), Z = -3.49, p < 0.001), hysteresis(24.4 J (12.8, 76.0) vs. 27.6 J (16.4, 54.4), Z = -2.61, p = 0.009), with loss of both disc height (7.0 mm (5.0, 10.5) vs 6.1 mm (4.0, 9.3), Z = -5.16, p < 0.001) and torsional stiffness (0.76 Nmdeg-1 (0.38, 1.07) vs. 0.66 Nmdeg-1 (0.38, 0.97), Z = -3.98, p < 0.001). Most FibGen repaired AF endured the entire testing procedure whereas only a minority of BioGlue repaired AF and all FibGen+Scaffold repaired AF failed (6/10 vs. 3/12 vs. 0/6 respectively, p = 0.041). Both BioGlue and FibGen+Scaffold repaired AF partially restored disc height (0.47 mm (0.07, 2.41), p = 0.048 and 1.52 mm (0.41, 2.57), p = 0.021 respectively) compared to sham treatment (0.08 mm (-0.63, 0.88)) whereas FibGen-only repaired AF had no such effect (0.04 mm (-0.73, 1.13), U = 48.0, p = 1). The AF injury model demonstrated considerable change of FSU mechanics that could be partially restored by use of an AF sealant. While inclusion of a volumetric collagen scaffold led to repair failure, use of FibGen alone demonstrated clinically relevant promise for prevention of mechanical reherniation, outperforming an FDA approved sealant in this ex vivo test series.

Abstract
Numerous studies show promise for cell-based tissue engineering strategies aiming to repair painful intervertebral disc (IVD) degeneration. However, clinical translation to human IVD repair is slow. In the present study, the regenerative potential of an autologous nucleus pulposus (NP)-cell-seeded thermoresponsive hyaluronic acid hydrogel in human lumbar IVDs was assessed under physiological conditions. First, agarose-encased in vitro constructs were developed, showing greater than 90 % NP cell viability and high proteoglycan deposition within HA-pNIPAM hydrogels following 3 weeks of dynamic loading. Second, a bovine-induced IVD degeneration model was used to optimise and validate T1ρ magnetic resonance imaging (MRI) for detection of changes in proteoglycan content in isolated intact IVDs. Finally, isolated intact human lumbar IVDs were pre-scanned using the established MRI sequence. Then, IVDs were injected with HA-pNIPAM hydrogel alone or autologous NP-cell-seeded. Next, the treated IVDs were cultured under cyclic dynamic loading for 5 weeks. Post-treatment T1ρ values were significantly higher as compared to pre-treatment scans within the same IVD and region of interest. Histological evaluation of treated human IVDs showed that the implanted hydrogel alone accumulated proteoglycans, while those that contained NP cells also displayed neo-matrix-surrounded cells within the gel. The study indicated a clinical potential for repairing early degenerative human IVDs using autologous cells/hydrogel suspensions. This unique IVD culture set-up, combined with the long-term physiological culture of intact human IVDs, allowed for a more clinically relevant evaluation of human tissue repair and regeneration, which otherwise could not be replicated using the available in vitro and in vivo models.

Abstract
Introduction: Cement extravasation during vertebroplasty (VP) is the most commonly reported complication. Cement viscosity is considered the single most important predictor of the risk of extravasation. Certainly, injecting high-viscosity cement (HVC) is difficult to utilize in real practice. We invented a new device capable of injecting high-viscosity with ease and at a distance to avoid radiation. The aim of this study is to confirm the efficacy and safety of the new device on cadaveric vertebrae. Methodology: A 126 osteoporotic vertebral bodies were harvested from cadavers. Eighty vertebrae were included in the study. Computer-randomization software was used to allocate specimens over two main groups, Conventional VP and New Device. Both groups were further subdivided into two subgroups; high-viscosity and low-viscosity. A custom device was used on each vertebra to induce a compression fracture. Results: Injecting HVC was associated with a lower leakage volume compared with low-viscosity cement. HVC was associated with no leakage into the spinal canal. It was also associated with a low incidence of vascular extravasation (P < 0.001). The mean volume of cement leakage in the low-viscosity group was 0.23 and 0.15 cc, for the Conventional VP and New Device, respectively. In both groups, the most common site for leakage was the vertebral end plate, which was exhibited more in the low-viscosity group (71.5%) compared with the high-viscosity group (42.5%). The preset target amount of cement to be injected was reached in 99% of the time when injecting HVC with the New Device, compared with 62% using the Conventional VP. In both groups, there was no correlation between the amount of cement injected and the amount of leakage. Conclusion: The new device is capable of injecting HVC easily, with a lower incidence of cement leakage. It also minimized the risk of radiation exposure to the surgeon.

Abstract
AIM The operative treatment for non-metastatic appendiceal carcinoma is controversial despite the recommendation of right hemicolectomy (RH) by many researchers. The aim of this population-based study was to compare outcomes after RH and less radical resection than right hemicolectomy (LRH). METHOD A total of 1144 patients who underwent resection with additional lymphadenectomy of Stages I-III appendiceal carcinoma from 2004 to 2012 were identified in the Surveillance, Epidemiology and End Results database. Overall survival (OS) and cancer-specific survival (CSS) after RH and LRH were assessed by unadjusted and risk-adjusted Cox regression analysis and by propensity score matched analysis. RESULTS A total of 855 (74.7%) patients underwent RH and 289 (25.3%) underwent LRH. In an unadjusted analysis, survival after LRH and RH did not differ in OS [hazard ratio (HR) 0.95, 95% CI 0.71-1.26, P = 0.707] and CSS (HR 0.95, 95% CI 0.69-1.32, P = 0.762). The 5-year OS and CSS in patients who underwent RH were 71.6% (95% CI 67.8-75.6%) and 76.4% (95% CI 72.8-80.3) compared with 73.8% (95% CI 67.9-80.2) and 78.7% (95% CI 73.2-84.7) in patients with LRH, respectively. No relevant difference in survival between LRH and RH could be observed in a multivariable analysis (OS, HR 0.90, 95% CI 0.65-1.25, P = 0.493; CSS, HR 0.87, 95% CI 0.60-1.26, P = 0.420) and after propensity score adjusted analysis (OS, HR 0.87, 95% CI 0.62-1.22, P = 0.442; CSS, HR 0.97, 95% CI 0.67-1.40, P = 0.883). CONCLUSIONS In this retrospective analysis, survival after RH for non-metastatic appendiceal carcinoma was not statistically significantly superior to LRH. Hence, LRH with lymphadenectomy might be sufficient for treatment of non-metastatic appendiceal carcinoma.

Abstract
OBJECTIVE This study aims to improve the understanding of the anatomic variations along the thoracic and lumbar spine encountered during an all-posterior vertebrectomy, and reconstruction procedure. This information will help improve our understanding of human spine anatomy and will allow better planning for a vertebral body replacement (VBR) through either a transpedicular or costotransversectomy approach. SUMMARY OF BACKGROUND DATA The major challenge to a total posterior approach vertebrectomy and VBR in the thoracolumbar spine lies in the preservation of important neural structures. METHODS This was a retrospective analysis. Hundred normal magnetic resonance imaging (MRI) spinal studies (T1-L5) on sagittal T2-weighted MRI images were studied to quantify: (1) mid-sagittal vertebral body (VB) dimensions (anterior, midline, and posterior VB height), (2) midline VB and associated intervertebral discs height, (3) mean distance between adjacent spinal nerve roots (DNN) and mean distance between the inferior endplate of the superior vertebrae to its respective spinal nerve root (DNE), and (4) posterior approach expansion ratio (PAER). RESULTS (1) The mean anterior VB height gradually increased craniocaudally from T1 to L5. The mean midline and posterior VB height showed a similar pattern up to L2. Mean posterior VB height was larger than the mean anterior VB height from T1 to L2, consistent with anterior wedging, and then measured less than the mean anterior VB height, indicating posterior wedging. (2) Midline VB and intervertebral disc height gradually increased from T1 to L4. (3) DNN and DNE were similar, whereby they gradually increased from T1 to L3. (5) Mean PAER varied between 1.69 (T12) and 2.27 (L5) depending on anatomic level. CONCLUSIONS The dimensions of the thoracic and lumbar vertebrae and discs vary greatly. Thus, any attempt at carrying out a VBR from a posterior approach should take into account the specifications at each spinal level.

Abstract
BACKGROUND Whereas the poor prognosis of signet ring cell adenocarcinomas of the appendix is well known, the significance of mucinous histology remains unclear. The aim of this population-based study was to evaluate if mucinous histology is an independent prognostic factor in appendiceal adenocarcinomas. METHODS Patients with stage I-III adenocarcinoma of the appendix who underwent surgery between 2004 and 2012 were identified in the Surveillance, Epidemiology, and End Results database. Overall survival (OS) and cancer-specific survival (CSS) were assessed using risk-adjusted Cox proportional hazards regression models and propensity score methods. RESULTS Overall, 980 patients with appendix cancer were included, of which 449 (45.8 %) had a mucinous histology. In an unadjusted analysis, the 5-year OS and CSS in patients with a mucinous adenocarcinoma (MC) was 76.8 % (95 % confidence interval (95 %CI): 72.1-81.7 %) and 81.0 % (95 %CI: 76.6-85.6 %), respectively, compared with 70.0 % (95 %CI: 65.1-75.3 %) and 76.2 % (95 %CI: 71.5-81.2 %) in patients with non-mucinous adenocarcinoma (NMC) (P = 0.082 and P = 0.368). In multivariable analysis, no impact on survival was observed for OS (HR = 1.22, 95 %CI: 0.89-1.68, P = 0.208) and CSS (HR = 1.21, 95 %CI: 0.84-1.74, P = 0.296). After propensity score matching, nearly identical survival rates were observed (OS: HR = 1.03, 95 %CI: 0.71-1.49, P = 0.881 and CSS: HR = 1.05, 95 %CI: 0.70-1.59, P = 0.803). CONCLUSIONS The present population-based, propensity score matched analysis shows that mucinous histology does not affect survival in stage I-III appendiceal adenocarcinoma patients. Therefore, the same treatment strategies can be applied for patients with NMC and MC of the appendix.

Abstract
BACKGROUND Appendiceal neuroendocrine tumors (aNET) are a common entity in routine medical care, with a rate per appendectomy as high as 0.3-0.9 %. Considering the relatively young age at diagnosis for these patients, exact information about the long-term prognosis of aNET is required. Survival rates vary substantially between 71 and 100 % and are mostly limited to 5 years. This investigation assessed the long-term mortality rates of patients who underwent aNET resections at fifteen hospitals. METHODS Between 1990 and 2003, the 10-year survival rates of 79 patients were analyzed using risk-adjusted Cox proportional hazard regression models adjusted for population-based baseline mortality. Additionally, prognostic factors for the oncologic outcomes were assessed. RESULTS The median follow-up of all patients was 12.1 and 13.7 years for those alive. All patients underwent curative R0 resections. No distant metastases were diagnosed. A total of 31 (39.2 %), 29 (36.7 %), 18 (22.8 %), and 1 (1.3 %) patients had stage I, IIA, IIB, and IIIB aNET, respectively, according to the latest classification by the European Neuroendocrine Tumor Society. The 10-year overall and relative survival rates were 83.6 % (95 % CI 75.5-92.6 %) and 96.7 % (95 % CI 87.5-107 %), respectively. The 10-year relative survival rate after resection of aNET did not differ from the survival of the average national population with the same age and gender (p = 0.947). Second primary malignancies (hazard ratio of death 7.0, 95 % CI 1.6-30.6) were identified as a significant prognosticator for long-term survival. CONCLUSIONS Long-term survival is not significantly depreciated after the curative resection of aNET.

Abstract
BACKGROUND In the city of Zurich, vision screening is performed by school medical services as part of the legally compulsory preventive medical examinations. We retrospectively evaluated the results of the 2011-2012 school year. PATIENTS AND METHODS Preventive medical examinations by the school medical services were performed in all kindergartens. The examinations were mandatory for first, second and eighth grade children, whilst those for the fourth grade were voluntary. The basic diagnostic testing consisted of monocular visual acuity (Snellen E chart) for all age groups and the stereopsis test (TNO test) in kindergartens. RESULTS Vision screening was performed on 7499 children. 1471 first graders (55 %), 201 fourth graders (11 %) and 211 eighth graders (12.3 %) did not pass the examinations. In 33.7 % of the children who underwent the follow-up examination from an ophthalmologist, amblyogenic potential was found. CONCLUSIONS Vision screening by the school medical services enrols most of the children from a single age group. The Snellen E charts used for the monocular distance acuity, together with the TNO stereo test, appear to constitute an effective testing combination. Ophthalmological follow-up examinations of the affected children revealed that one third were afflicted by amblyogenic factors.

Abstract
Low back pain originating from intervertebral disc (IVD) degeneration affects the quality of life for millions of people, and it is a major contributor to global healthcare costs. Long-term culture of intact IVDs is necessary to develop ex vivo models of human IVD degeneration and repair, where the relationship between mechanobiology, disc matrix composition and metabolism can be better understood. A bioreactor was developed that facilitates culture of intact human IVDs in a controlled, dynamically loaded environment. Tissue integrity and cell viability was evaluated under 3 different loading conditions: low 0.1-0.3, medium 0.1-0.3 and high 0.1-1.2 MPa. Cell viability was maintained > 80 % throughout the disc at low and medium loads, whereas it dropped to approximately 70 % (NP) and 50 % (AF) under high loads. Although cell viability was affected at high loads, there was no evidence of sGAG loss, changes in newly synthesised collagen type II or chondroadherin fragmentation. Sulphated GAG content remained at a stable level of approximately 50 µg sGAG/mg tissue in all loading protocols. To evaluate the feasibility of tissue repair strategies with cell supplementation, human NP cells were transplanted into discs within a thermoreversible hyaluronan hydrogel. The discs were loaded under medium loads, and the injected cells remained largely localised to the NP region. This study demonstrates the feasibility of culturing human IVDs for 14 days under cyclic dynamic loading conditions. The system allows the determination a safe range-of-loading and presents a platform to evaluate cell therapies and help to elucidate the effect of load following cell-based therapies.

Abstract
Study Design A biomechanical and radiographic study using vertebral analogues. Objectives Kyphoplasty and vertebroplasty are widely used techniques to alleviate pain in fractures secondary to osteoporosis. However, cement leakage toward vital structures like the spinal cord can be a major source of morbidity and even mortality. We define safe cement injection as the volume of the cement injected into a vertebra before the cement leakage occurs. Our objective is to compare the amount of cement that can be safely injected into an osteoporotic vertebra with simulated compression fracture using either vertebroplasty or balloon kyphoplasty techniques. Methods Forty artificial vertebral analogues made of polyurethane with osteoporotic cancellous matrix representing the L3 vertebrae were used for this study and were divided into four groups of 10 vertebrae each. The four groups tested were: low-viscosity cement injected using vertebroplasty, high-viscosity cement injected using vertebroplasty, low-viscosity cement injected using balloon kyphoplasty, and high-viscosity cement injected using balloon kyphoplasty. The procedures were performed under fluoroscopic guidance. The injection was stopped when the cement started protruding from the created vascular channel in the osteoporotic vertebral fracture model. The main outcome measured was the volume of the cement injected safely into a vertebra before leakage through the posterior vascular channel. Results The highest volume of the cement injected was in the vertebroplasty group using high-viscosity cement, which was almost twice the injected volume in the other three groups. One-way analysis of variance comparing the four groups showed a statistically significant difference (p < 0.005). Conclusions High-viscosity cement injected using vertebroplasty delivers more cement volume before cement leakage and fills the vertebral body more uniformly when compared with balloon kyphoplasty in osteoporotic vertebrae with compression fractures.

Abstract
BACKGROUND The aim of this analysis was to assess the predictive value of C-reactive protein (CRP) for the early detection of postoperative infectious complications after a variety of abdominal operations. METHODS A meta-analysis of seven cohort studies from a single institution was performed. Laparoscopic gastric bypass and colectomies, as well as open resections of cancer of the colon, rectum, pancreas, stomach and oesophagus, were included. The predictive value of CRP was assessed by the area under the curve (AUC) of the receiver operating characteristic (ROC) curve. RESULTS Of 1986 patients, 577 (29·1 (95 per cent c.i. 27·1 to 31·3) per cent) had at least one postoperative infectious complication. Patients undergoing laparoscopic gastric bypass (383 patients) or colectomy (285), and those having open gastric (97) or colorectal (934) resections were combined in a meta-analysis. Patients who had resection for cancer of the oesophagus (41) or pancreas (246) were analysed separately owing to heterogeneity. CRP levels 4 days after surgery had the highest diagnostic accuracy (AUC 0·76, 95 per cent c.i. 0·73 to 0·78). Sensitivity and specificity were 68·5 (60·6 to 75·5) and 71·6 (66·6 to 76·0) per cent respectively. Positive and negative predictive values were 50·4 (46·0 to 54·8) and 84·3 (80·8 to 87·3) per cent. The threshold CRP varied according to the procedure performed. CONCLUSION The negative predictive value of serum CRP concentration on day 4 after surgery facilitates reliable exclusion of postoperative infectious complications.

Abstract
Excessive mechanical loading or acute trauma to intervertebral discs (IVDs) is thought to contribute to degeneration and pain. However, the exact mechanisms by which mechanical injury initiates and promotes degeneration remain unclear. This study investigates biochemical changes and extracellular matrix disruption in whole-organ human IVD cultures following acute mechanical injury. Isolated healthy human IVDs were rapidly compressed by 5% (non-injured) or 30% (injured) of disc height. 30% strain consistently cracked cartilage endplates, confirming disc trauma. Three days post-loading, conditioned media were assessed for proteoglycan content and released cytokines. Tissue extracts were assessed for proteoglycan content and for aggrecan integrity. Conditioned media were applied to PC12 cells to evaluate if factors inducing neurite growth were released. Compared to controls, IVD injury caused significant cell death. Injury also caused significantly reduced tissue proteoglycan content with a reciprocal increase of proteoglycan content in culture media. Increased aggrecan fragmentation was observed in injured tissue due to increased matrix metalloproteinase and aggrecanase activity. Injured-IVD conditioned media contained significantly elevated interleukin (IL)-5, IL-6, IL-7, IL-8, MCP-2, GROα, and MIG, and ELISA analysis showed significantly increased nerve growth factor levels compared to non-injured media. Injured-disc media caused significant neurite sprouting in PC12 cells compared to non-injured media. Acute mechanical injury of human IVDs ex vivo initiates release of factors and enzyme activity associated with degeneration and back pain. This work provides direct evidence linking acute trauma, inflammatory factors, neo-innervation and potential degeneration and discogenic pain in vivo.

Abstract
Presently, there are no established treatments to prevent, stop or even retard back pain arising from disc degeneration. Previous studies have shown that Link N can act as a growth factor and stimulate the synthesis of proteoglycans and collagens, in IVD. However, the sequences in Link N involved in modulating cellular activity are not well understood. To determine if disc cells can proteolytically process Link N, human disc cells were exposed to native Link N over a 48 h period and mass spectrometric analysis revealed that a peptide spanning residues 1-8 was generated in the presence of AF cells but not NP cells. Link N 1-8 significantly induced proteoglycan production in the presence of IL-1β NP and AF cells, confirming that the biological effect is maintained in the first 8 amino acids of the peptide and indicating that the effect is sustained in an inflammatory environment. Thus Link-N 1-8 could be a promising candidate for biologically induced disc repair, and the identification of such a stable specific peptide may facilitate the design of compounds to promote disc repair and provide alternatives to surgical intervention for early stage disc degeneration.

Abstract
A hallmark of early IVD degeneration is a decrease in proteoglycan content. Progression will eventually lead to matrix degradation, a decrease in weight bearing capacity and loss of disc height. In the final stages of IVD degradation, fissures appear in the annular ring allowing extrusion of the NP. It is crucial to understand the interplay between mechanobiology, disc composition and metabolism to be able to provide exercise recommendations to patients with early signs of disc degeneration. This study evaluates the effect of physiological loading compared to no loading on matrix homeostasis in bovine discs with induced degeneration. Bovine discs with trypsin-induced degeneration were cultured for 14 days in a bioreactor under dynamic loading with maintained metabolic activity. Chondroadherin abundance and structure was used to confirm that a functional matrix was preserved in the chosen loading environment. No change was observed in chondroadherin integrity and a non-significant increase in abundance was detected in trypsin-treated loaded discs compared to unloaded discs. The proteoglycan concentration in loaded trypsin-treated discs was significantly higher than in unloaded disc and the newly synthesised proteoglycans were of the same size range as those found in control samples. The proteoglycan showed an even distribution throughout the NP region, similar to that of control discs. Significantly more newly synthesised type II collagen was detected in trypsin-treated loaded discs compared to unloaded discs, demonstrating that physiological load not only stimulates aggrecan production, but also that of type II collagen. Taken together, this study shows that dynamic physiological load has the ability to repair the extracellular matrix depletion typical of early disc degeneration.

Abstract
BACKGROUND Early detection of infectious complications is urgently needed in the era of DRG-based compensation. This work assessed the diagnostic accuracy of c-reactive protein (CRP) level in the detection of infectious complications after laparoscopic colorectal resection. METHODS Laparoscopic colorectal resections were identified from a prospective database. Complications were graded according to the Dindo-Clavien classification. Surgical site infections were defined according to the Centers of Disease Control. CRP level was routinely measured until postoperative day (POD) 7. Uni- and multivariate analysis were performed. Diagnostic accuracy was evaluated using receiver operating curves. RESULTS 355 patients were operated for diverticulosis (88.7%), neoplasia (6.8%), and other causes (4.5%). Mean age and body mass index were 59.8 ± 13.7 years and 26.5 ± 15 kg/m(2). Left, right, and total laparoscopic colectomies were performed in 316, 33, and 6 patients. Complications occurred in 85 patients and 16 patients (4.5%) were reoperated. Fifty-one patients (14.4%) suffered from infectious complications at a median of 6 POD, while 9 anastomoses leaked (2.7%). In multivariate analysis, presence of an abscess at surgery was predictive of an infectious complication (OR 2.5, 95% CI 1.1-5.3), as were a body mass index >30 kg/m(2) and operative time >160 min in a bootstrap analysis. Overall, CRP peaked on POD 2 and declined thereafter. Most infectious complications were apparent starting on POD 6. A CRP <56 mg/l on POD 4 had a negative predictive value of 100% (95% CI 94.9-100%) to rule out infectious complications. Above 56 mg/l, sensitivity was 100% (95% CI 0.8-1) and specificity 49% (95% CI 0.4-0.6) for the development of infectious complications in the absence of clinical signs. This translated into a remarkable diagnostic accuracy of 78% (95% CI 0.7-0.9). CONCLUSION Monitoring CRP level in laparoscopic colorectal surgery demonstrated a high diagnostic accuracy for infectious complications, thus allowing for safe and early discharge.

Abstract
Intervertebral disc (IVD) degeneration is the most common cause of back pain. Presently there is no medical treatment, leaving surgery as the only offered option. Here we evaluate the potential of Link-N to promote extracellular matrix regeneration in human IVDs. Human disc cells cultured in alginate and intact human discs were exposed to a combination of Link-N and ³⁵SO₄ in the presence or absence of interleukin (IL)-1, and the effect on proteoglycan synthesis was evaluated. In addition, message levels of aggrecan, matrix metalloproteinase (MMP)-3, MMP-13, a Disintegrin And Metalloproteinase with Thrombospondin Motifs (ADAMTS)-4 and ADAMTS-5 were evaluated in alginate cultures. Human disc cells responded in a dose dependent manner with maximal proteoglycan synthesis at 1 µg/mL Link-N. Link-N treatment also induced proteoglycan synthesis in intact human discs, and a prolonged effect was found up to one week after Link-N treatment. Message levels of proteinases were decreased by Link-N in the presence of IL-1. Thus, Link-N can promote proteoglycan synthesis and deplete proteinase expression in adult human discs. Link-N could therefore be a promising candidate for biologically-induced disc repair, and could provide an alternative to surgical intervention for early stage disc degeneration.

Abstract
PURPOSE The aim of this study was to assess the putative impact of perioperative blood transfusions on overall survival in patients undergoing curative resection for stage III colon cancer by applying propensity scoring methods. METHODS In a single-center study, a total of 309 patients who underwent open curative resection for stages I-III colon cancer from 1996-2008 were assessed. The mean follow-up period was 47 ± 38 months. Transfused and non-transfused patients were compared using both Cox regression and propensity score analyses. RESULTS Overall, 148 patients (47.9 %) received blood transfusions. The patient characteristics were highly biased toward transfusions (propensity score 0.68 ± 0.22 vs. 0.30 ± 0.22, p <0.001). In the unadjusted analysis, blood transfusions were associated with a 90 % increased risk of overall mortality (hazard ratio 1.90, 95 % CI: 1.19-3.04, p = 0.001). The 5-year survival for patients receiving blood transfusions was 64.5 % (95 % CI: 56.0-74.3 %) compared with 80.1 % (95 % CI: 72.8-88.2 %) in those not receiving blood transfusions. In the propensity score-adjusted Cox regression analysis (hazard ratio: 0.85, 95 % CI = 0.53-1.37, p = 0.501), blood transfusions did not increase the risk of overall mortality. After risk adjustment, the 5-year survival rate for patients receiving blood transfusions was 66.6 % (95 % CI: 57.4-77.3 %) compared with 61.8 % (95 % CI: 51.9-73.7 %) for those who did not. CONCLUSION This study is the first propensity score-based analysis that provides evidence that poor oncological outcomes after curative colon cancer resection in patients receiving perioperative blood transfusions are due to the clinical circumstances that require the transfusions and are not due to the blood transfusions.

Abstract
BACKGROUND Reproducible and suitable animal models are required for in vivo experiments to investigate new biodegradable and osteoinductive biomaterials for augmentation of bones at risk for osteoporotic fractures. Sheep have especially been used as a model for the human spine due to their size and similar bone metabolism. However, although sheep and human vertebral bodies have similar biomechanical characteristics, the shape of the vertebral bodies, the size of the transverse processes, and the different orientation of the facet joints of sheep are quite different from those of humans making the surgical approach complicated and unpredictable. Therefore, an adequate and safe animal model for bone augmentation was developed using a standardized femoral and tibia augmentation site in sheep. METHODS The cancellous bone of the distal femur and proximal tibia were chosen as injection sites with the surgical approach via the medial aspects of the femoral condyle and proximal tibia metaphysis (n = 4 injection sites). For reproducible drilling and injection in a given direction and length, a custom-made c-shaped aiming device was designed. Exact positioning of the aiming device and needle positioning within the intertrabecular space of the intact bone could be validated in a predictable and standardized fashion using fluoroscopy. After sacrifice, bone cylinders (Ø 32 mm) were harvested throughout the tibia and femur by means of a diamond-coated core drill, which was especially developed to harvest the injected bone area exactly. Thereafter, the extracted bone cylinders were processed as non-decalcified specimens for μCT analysis, histomorphometry, histology, and fluorescence evaluation. RESULTS The aiming device could be easily placed in 63 sheep and assured a reproducible, standardized injection area. In four sheep, cardiovascular complications occurred during surgery and pulmonary embolism was detected by computed tomography post surgery in all of these animals. The harvesting and evaluative methods assured a standardized analysis of all samples. CONCLUSIONS This experimental animal model provides an excellent basis for testing new biomaterials for their suitability as bone augmentation materials. Concomitantly, similar cardiovascular changes occur during vertebroplasties as in humans, thus making it a suitable animal model for studies related to vertebroplasty.
