Abstract

We present a new three-dimensional seismic velocity model of the crustal and upper mantle structure for Mauna Loa and Kilauea volcanoes in Hawaii. Our model is derived from the first-arrival times of the compressional and shear waves from about 53,000 events on and near the Island of Hawaii between 1992 and 2009 recorded by the Hawaiian Volcano Observatory stations. The Vp model generally agrees with previous studies, showing high-velocity anomalies near the calderas and rift zones and low-velocity anomalies in the fault systems. The most significant difference from previous models is in V p/Vs structure. The high-Vp and high-V p/Vs anomalies below Mauna Loa caldera are interpreted as mafic magmatic cumulates. The observed low-Vp and high-V p/Vs bodies in the Kaoiki seismic zone between 5 and 15 km depth are attributed to the underlying volcaniclastic sediments. The high-Vp and moderate- to low-Vp/Vs anomalies beneath Kilauea caldera can be explained by a combination of different mafic compositions, likely to be olivine-rich gabbro and dunite. The systematically low-Vp and low-Vp/Vs bodies in the southeast flank of Kilauea may be caused by the presence of volatiles. Another difference between this study and previous ones is the improved Vp model resolution in deeper layers, owing to the inclusion of events with large epicentral distances. The new velocity model is used to relocate the seismicity of Mauna Loa and Kilauea for improved absolute locations and ultimately to develop a high-precision earthquake catalog using waveform cross-correlation data. ©2014.

Abstract

Objective: To investigate the oncological safety and potential cost savings of selective histopathological examination after appendectomy. Background: The necessity of routine histopathological examination after appendectomy has been questioned, but prospective studies investigating the safety of a selective policy are lacking. Methods: In this multicenter, prospective, cross-sectional study, inspection and palpation of the (meso)appendix was performed by the surgeon in patients with suspected appendicitis. The surgeon's opinion on additional value of histopathological examination was reported before sending all specimens to the pathologist. Main outcomes were the number of hypothetically missed appendiceal neoplasms with clinical consequences benefiting the patient (upper limit two-sided 95% confidence interval below 3:1000 considered oncologically safe) and potential cost savings after selective histopathological examination. Results: Seven thousand three hundred thirty-nine patients were included. After a selective policy, 4966/7339 (67.7%) specimens would have been refrained from histopathological examination. Appendiceal neoplasms with clinical consequences would have been missed in 22/4966 patients. In 5/22, residual disease was completely resected during additional surgery. Hence, an appendiceal neoplasm with clinical consequences benefiting the patient would have been missed in 1.01:1000 patients (upper limit 95% confidence interval 1.61:1000). In contrast, twice as many patients (10/22) would not have been exposed to potential harm due to re-resections without clear benefit, whereas consequences were neither beneficial nor harmful in the remaining seven. Estimated cost savings established by replacing routine for selective histopathological examination were 725,400 per 10,000 patients. Conclusions: Selective histopathological examination after appendectomy for suspected appendicitis is oncologically safe and will likely result in a reduction of pathologists' workload, less costs, and fewer re-resections without clear benefit.

Abstract

Item does not contain fulltext BACKGROUND: The aim of this study was to analyze the stoma-related reinterventions, complications and readmissions after an anterior resection for rectal cancer, based on a cross-sectional nationwide cohort study with 3-year follow-up. METHODS: Rectal cancer patients who underwent a resection with either a functional anastomosis, a defunctioned anastomosis, or Hartmann's procedure (HP) with an end colostomy in 2011 in 71 Dutch hospitals were included. The primary outcome was number of stoma-related reinterventions. RESULTS: Of the 2095 patients with rectal cancer, 1400 patients received an anterior resection and were included in this study; 257 received an initially functional anastomosis, 741 a defunctioned anastomosis, and 402 patients a HP. Of the 1400 included patients, 62% were males, 38% were females and the mean age was 67 years (SD 11.1). Following a primary functional anastomosis, 48 (19%) patients received a secondary stoma. Stoma-related complications occurred in six (2%) patients, requiring reintervention in one (0.4%) case. In the defunctioned anastomosis group, stoma-related complications were present in 92 (12%) patients, and required reintervention in 23 (3%) patients, in 10 (1%) of these more than 1 year after initial resection. Stoma-related complications occurred in 92 (23%) patients after a HP, and required reintervention in 39 (10%) patients in 17 (4%) of cases more than 1 year after initial resection. The permanent stoma rate was 11% and 20%, in the functional anastomosis and the defuctioned anastomosis group, respectively. The end colostomy in the HP group was reversed in 4% of cases. CONCLUSIONS: Construction of a stoma after resection for rectal cancer with preservation of the sphincter is accompanied with long-term stoma-related morbidity. Stoma complications are more frequent after a HP. Even after 1 year, a significant number of reinterventions are required.

Abstract

Contains fulltext : 239366.pdf (Publisher’s version ) (Open Access) AIM: Nonrestorative low anterior resection (n-rLAR) (also known as low Hartmann's) is performed for rectal cancer when a poor functional outcome is anticipated or there have been problems when constructing the anastomosis. Compared with restorative LAR (rLAR), little oncological outcome data are available for n-rLAR. The aim of this study was to compare oncological outcomes between rLAR and n-rLAR for primary rectal cancer. METHOD: This was a nationwide cross-sectional comparative study including all elective sphincter-saving LAR procedures for nonmetastatic primary rectal cancer performed in 2011 in 71 Dutch hospitals. Oncological outcomes of patients undergoing rLAR and n-rLAR were collected in 2015; the data were evaluated using Kaplan-Meier survival analysis and the results compared using log-rank testing. Uni- and multivariable Cox regression analysis was used to evaluate the association between the type of LAR and oncological outcome measures. RESULTS: A total of 1197 patients were analysed, of whom 892 (75%) underwent rLAR and 305 (25%) underwent n-rLAR. The 3-year local recurrence (LR) rate was 3% after rLAR and 8% after n-rLAR (P

Background: The aim of this study was to determine the prognostic value of lymph node count (LNC) and lymph node ratio (LNR) in rectal cancer after neoadjuvant chemoradiotherapy (CRT). Methods: Patients who underwent neoadjuvant CRT and total mesorectal excision (TME) for Stage I–III rectal cancer were selected from a cross-sectional study including 71 Dutch centres. Primary outcome parameters were disease-free survival (DFS) and overall survival (OS). Prognostic significance of LNC and LNR (cut-off values 0.15, 0.20, 0.30) was tested for different (sub)groups. Results: From 2095 registered patients, 458 were included, of which 240 patients with LNC < 12 and 218 patients with LNC ≥ 12. LNC was not significantly associated with DFS (p = 0.35) and OS (p = 0.59). In univariable analysis, LNR was significantly associated with DFS and OS in the whole cohort and LNC subgroups, but not in multivariable analysis. Conclusions: LNC was not associated with long-term oncological outcome in rectal cancer patients treated with CRT, nor was LNR when corrected for N-stage. However, LNR might be used to identify subgroups of node-positive patients with a favourable outcome.

Abstract

Contains fulltext : 215772.pdf (Publisher’s version ) (Open Access) BACKGROUND: The time interval between CRT and surgery in rectal cancer patients is still the subject of debate. The aim of this study was to first evaluate the nationwide use of restaging magnetic resonance imaging (MRI) and its impact on timing of surgery, and, second, to evaluate the impact of timing of surgery after chemoradiotherapy (CRT) on short- and long-term outcomes. METHODS: Patients were selected from a collaborative rectal cancer research project including 71 Dutch centres, and were subdivided into two groups according to time interval from the start of preoperative CRT to surgery (< 14 and >/= 14 weeks). RESULTS: From 2095 registered patients, 475 patients received preoperative CRT. MRI restaging was performed in 79.4% of patients, with a median CRT-MRI interval of 10 weeks (interquartile range [IQR] 8-11) and a median MRI-surgery interval of 4 weeks (IQR 2-5). The CRT-surgery interval groups consisted of 224 (< 14 weeks) and 251 patients (>/= 14 weeks), and the long-interval group included a higher proportion of cT4 stage and multivisceral resection patients. Pathological complete response rate (n = 34 [15.2%] vs. n = 47 [18.7%], p = 0.305) and CRM involvement (9.7% vs. 15.9%, p = 0.145) did not significantly differ. Thirty-day surgical complications were similar (20.1% vs. 23.1%, p = 0.943), however no significant differences were found for local and distant recurrence rates, disease-free survival, and overall survival. CONCLUSIONS: These real-life data, reflecting routine daily practice in The Netherlands, showed substantial variability in the use and timing of restaging MRI after preoperative CRT for rectal cancer, as well as time interval to surgery. Surgery before or after 14 weeks from the start of CRT resulted in similar short- and long-term outcomes.

Abstract

Aim: Nonrestorative low anterior resection (n‐rLAR) (also known as low Hartmann's) is performed for rectal cancer when a poor functional outcome is anticipated or there have been problems when constructing the anastomosis. Compared with restorative LAR (rLAR), little oncological outcome data are available for n‐rLAR. The aim of this study was to compare oncological outcomes between rLAR and n‐rLAR for primary rectal cancer. Method: This was a nationwide cross‐sectional comparative study including all elective sphincter‐saving LAR procedures for nonmetastatic primary rectal cancer performed in 2011 in 71 Dutch hospitals. Oncological outcomes of patients undergoing rLAR and n‐rLAR were collected in 2015; the data were evaluated using Kaplan–Meier survival analysis and the results compared using log‐rank testing. Uni‐ and multivariable Cox regression analysis was used to evaluate the association between the type of LAR and oncological outcome measures. Results: A total of 1197 patients were analysed, of whom 892 (75%) underwent rLAR and 305 (25%) underwent n‐rLAR. The 3‐year local recurrence (LR) rate was 3% after rLAR and 8% after n‐rLAR (P < 0.001). The 3‐year disease‐free survival and overall survival rates were 77% (rLAR) vs 62% (n‐rLAR) (P < 0.001) and 90% (rLAR) vs 75% (n‐rLAR) (P < 0.001), respectively. In multivariable Cox analysis, n‐rLAR was independently associated with a higher risk of LR (OR = 2.95) and worse overall survival (OR = 1.72). Conclusion: This nationwide study revealed that n‐rLAR for rectal cancer was associated with poorer oncological outcome than r‐LAR. This is probably a noncausal relationship, and might reflect technical difficulties during low pelvic dissection in a subset of those patients, with oncological implications. [ABSTRACT FROM AUTHOR]

Abstract

BACKGROUND: Stoma reversal is often considered a straightforward procedure with low short-term complication rates. The aim of this study was to determine the rate of incisional hernia following stoma reversal and identify risk factors for its development.METHODS: This was an observational study of consecutive patients who underwent stoma reversal between 2009 and 2015 at a teaching hospital. Patients followed for at least 12 months were eligible. The primary outcome was the development of incisional hernia at the previous stoma site. Independent risk factors were assessed using multivariable logistic regression analysis.RESULTS: After a median follow-up of 24 (range 12-89) months, 110 of 318 included patients (34·6 per cent) developed an incisional hernia at the previous stoma site. In 85 (77·3 per cent) the hernia was symptomatic, and 72 patients (65·5 per cent) underwent surgical correction. Higher BMI (odds ratio (OR) 1·12, 95 per cent c.i. 1·04 to 1·21), stoma prolapse (OR 3·27, 1·04 to 10·27), parastomal hernia (OR 5·08, 1·30 to 19·85) and hypertension (OR 2·52, 1·14 to 5·54) were identified as independent risk factors for the development of incisional hernia at the previous stoma site. In addition, the risk of incisional hernia was greater in patients with underlying malignant disease who had undergone a colostomy than in those who had had an ileostomy (OR 5·05, 2·28 to 11·23).CONCLUSION: Incisional hernia of the previous stoma site was common and frequently required surgical correction. Higher BMI, reversal of colostomy in patients with an underlying malignancy, stoma prolapse, parastomal hernia and hypertension were identified as independent risk factors.

Abstract

Aim A Snapshot study design eliminates changes in treatment and outcome over time. This population based Snapshot study aimed to determine current practice and outcome of rectal cancer treatment with published landmark randomized controlled trials as a benchmark.Method In this collaborative research project, the dataset of the Dutch Surgical Colorectal Audit was extended with additional treatment and long-term outcome data. All registered patients who underwent resection for rectal cancer in 2011 were eligible. Baseline characteristics and outcome were evaluated against the results of the Dutch TME trial and the COLOR II trial from which the original datasets were obtained.Results A total of 71 hospitals participated, and data were completed for 2102 out of the potential 2633 patients (79.8%). Median follow-up was 41 (interquartile range 25-47) months. Overall circumferential resection margin (CRM) involvement was 9.3% in the Snapshot cohort and 18.5% in the Dutch TME trial. CRM positivity after laparoscopic resection was 7.8% in the Snapshot and 9.5% in the COLOR II trial. Three-year overall local recurrence rate in the Snapshot was 5.9%, with a disease-free survival of 67.1% and overall survival of 79.5%. Benchmarking with the randomized controlled trials revealed an overall favourable long-term outcome of the Snapshot cohort.Conclusion This study showed that current rectal cancer care in a large unselected Dutch population is of high quality, with less positive CRM since the TME trial and oncologically safe implementation of minimally invasive surgery after the COLOR II trial.

Abstract

OBJECTIVE: To investigate whether an ileostomy or colostomy should be preferred in patients requiring temporary double-barrel stoma construction and in whom it is technically possible to construct both types. DESIGN: Systematic literature search and retrospective comparative analysis. METHOD: PubMed, Embase and the Cochrane Library were searched for all literature comparing loop ileostomy and loop colostomy. In addition, we retrospectively analysed 361 patients who had received a loop ileostomy or loop colostomy designed to be temporary between 2009 and 2015 in our hospital, Meander Medisch Centrum, Amersfoort, the Netherlands. Outcome measures were: quality of life, short-term and long-term complications. RESULTS: The literature search yielded 2092 studies, of which eight were ultimately included. Ileostomy was the preferred stoma in the overall conclusion of six of these studies; no preference was given in the other two. In addition, we analyzed 361 patients from our own hospital in whom a temporary deviating stoma was constructed. 49.6% (n = 179) had a colostomy constructed, the other 50.4% (n = 182) an ileostomy. Significantly fewer stoma retractions (p < 0.01) and incisional hernias (p < 0.01) were reported in the loop ileostomy group. Patients with an ileostomy, however, more often presented with a high-output stoma (p < 0.01) resulting in dehydration (p = 0.03). CONCLUSION: A loop ileostomy has a number of advantages over a colostomy. However, in patients with an increased risk of dehydration or compromised renal function, colostomy construction should be seriously considered given the higher complication risk if a high-output stoma develops.

Abstract

Background Stoma reversal is often considered a straightforward procedure with low short‐term complication rates. The aim of this study was to determine the rate of incisional hernia following stoma reversal and identify risk factors for its development. Methods This was an observational study of consecutive patients who underwent stoma reversal between 2009 and 2015 at a teaching hospital. Patients followed for at least 12 months were eligible. The primary outcome was the development of incisional hernia at the previous stoma site. Independent risk factors were assessed using multivariable logistic regression analysis. Results After a median follow‐up of 24 (range 12–89) months, 110 of 318 included patients (34·6 per cent) developed an incisional hernia at the previous stoma site. In 85 (77·3 per cent) the hernia was symptomatic, and 72 patients (65·5 per cent) underwent surgical correction. Higher BMI (odds ratio (OR) 1·12, 95 per cent c.i. 1·04 to 1·21), stoma prolapse (OR 3·27, 1·04 to 10·27), parastomal hernia (OR 5·08, 1·30 to 19·85) and hypertension (OR 2·52, 1·14 to 5·54) were identified as independent risk factors for the development of incisional hernia at the previous stoma site. In addition, the risk of incisional hernia was greater in patients with underlying malignant disease who had undergone a colostomy than in those who had had an ileostomy (OR 5·05, 2·28 to 11·23). Conclusion Incisional hernia of the previous stoma site was common and frequently required surgical correction. Higher BMI, reversal of colostomy in patients with an underlying malignancy, stoma prolapse, parastomal hernia and hypertension were identified as independent risk factors.

Abstract

Purpose: A substantial part (21–35%) of defunctioning stomas created during resection for colorectal cancer will never be reversed. Known risk factors for non-closure are age, peri- or postoperative complications, comorbidity, and tumor stage. However, studies performed to identify these risk factors mostly focus on rectal cancer and include both preoperative and postoperative factors. This study aims to identify preoperative risk factors for non-reversal of intended temporary stomas created during acute resection of left-sided obstructive colon cancer (LSOCC) with primary anastomosis. Methods: All patients who underwent emergency resection for LSOCC with primary anastomosis and a defunctioning stoma between 2009 and 2016 were selected from the Dutch ColoRectal Audit, and additional data were collected in the local centers. Multivariable analysis was performed to identify independent preoperative factors for non-closure of the stoma. Results: A total of 155 patients underwent acute resection for LSOCC with primary anastomosis and a defunctioning stoma. Of these, 51 patients (32.9%) did not have their stoma reversed after a median of 53 (range 7–104) months of follow-up. In multivariable analysis, hemoglobin < 7.5 mmol/L (odds ratio (OR) 4.79, 95% confidence interval (95% CI) 1.60–14.38, p = 0.005), estimated glomerular filtration rate (eGFR) ≤ 45 mL/min/1.73 m2 (OR 4.64, 95% CI 1.41–15.10, p = 0.011), and metastatic disease (OR 6.12, 95% CI 2.35–15.94, p < 0.001) revealed to be independent predictors of non-closure. Conclusions: Anemia, impaired renal function, and metastatic disease at presentation were found to be independent predictors for non-reversal of intended temporary stomas in patients who underwent acute resection for LSOCC. In patients who have an increased risk of non-reversal, the surgeon should consider a Hartmann's procedure. [ABSTRACT FROM AUTHOR]

Abstract

[1] A systematic survey of 3 years of L band interferometric synthetic aperture radar (InSAR) measurements of the Central American Volcanic Arc shows a striking lack of magmatic deformation. We make measurements at 20 of the 26 historically active volcanoes and demonstrate that none were deforming magmatically (2007-2010), although we do measure shallow subsidence associated with flow deposits and edifice loading at three volcanoes. The minimum detection rates for our survey, as estimated from the variance in time series of radar path delay, are relatively high due to strong variability of tropospheric water vapor. We compare the average detection threshold (2.4 cm/yr) to published InSAR measurements and show that the majority (∼78%) of deformation events would have been measurable with the same level of noise as Central America. We calculate that if magmatic volcano deformation were spread evenly across historically active volcanoes worldwide, the probability of none of Central America's 26 volcanoes deforming would be < 1%. The lack of magmatic deformation in Central America may be indicative of differences in magma storage relative to other well-studied continental arcs. The high proportion of basalts that ascend directly from depth relative to andesites stored in the shallow crust may limit the potential for high magnitude deformation. Magma stored in vertically elongated reservoirs and high parental melt volatile contents that result in bubble-rich, compressible magmas at shallow depths may also reduce surface deformation. We consider the measurement and analysis of a lack of deformation at active volcanoes to be essential for realizing the potential of regional scale InSAR surveys. ©2013. American Geophysical Union.
