Asserts the increase awareness for an abdominal aortic aneurysm in women in Netherlands. Distinction of mortality rates between sexes; Percentage of in-hospital mortality in men and women.

Background Brothers of patients with an abdominal aortic aneurysm (AAA) are at high risk. In the present study brothers of patients who underwent elective AAA surgery were invited for aneurysm screening and the psychological consequences studied. Methods All brothers over the age of 50 years were invited for abdominal ultrasonography. They were asked to complete a standard psychological well-being questionnaire both before, and 3 months after screening. Results Some 571 brothers were identified: 251 were dead, 35 lived abroad, 16 could not be contacted for other reasons, 46 refused to participate and 13 were already known to have an AAA. Some 210 subjects (37·8 per cent) accepted the offer of screening. A new AAA was detected in 26 (12·3 per cent, 95 per cent confidence interval 8–18 per cent) of the men screened resulting in an overall prevalence of 18 per cent (95 per cent confidence interval 13–26 per cent). Eight (3·8 per cent) aneurysms were 5 cm or more in diameter and elective surgery was performed in five patients (2·4 per cent). The psychological dimensions of well-being (depression, anxiety, energy, and positive well-being) had not changed significantly 3 months after screening. Conclusion The prevalence of AAA in brothers of patients with AAA is far higher than in the overall male population of the same age. Screening does not seem to have a negative influence on psychological well-being. [ABSTRACT FROM AUTHOR]

Background: Present theory is that uncomplicated and complicated appendicitis are different entities. Recent studies suggest it is safe to delay surgery in patients with uncomplicated appendicitis. We hypothesize that patients with complicated appendicitis are at higher risk for postoperative complications when surgery is delayed. Methods: Data was used from the multicenter, prospective SNAPSHOT appendicitis study of 1975 patients undergoing surgery for suspected appendicitis. Adult patients (≥ 18 years) who underwent appendectomy for appendicitis were included in this study. The primary outcome was the difference in postoperative complications between patients with complicated appendicitis who were operated within and after 8 h after hospital presentation. Secondary outcomes were the incidence of both uncomplicated and complicated appendicitis in relationship to delay of appendectomy. Follow-up was 30 days. A multivariable analysis was performed. Results: Of 1341 adult patients with appendicitis, 34.3% had complicated appendicitis. In patients with complicated appendicitis, 22.8% developed a postoperative complication compared to 8.2% for uncomplicated appendicitis (P < 0.001). Delay in surgery (> 8 h) increased the complication rate in patients with complicated appendicitis (28.1%) compared to surgery within 8 h (18.3%; P = 0.01). Multivariate analysis showed a delay in surgery as an independent predictor for a postoperative complication in patients with complicated appendicitis (OR 1.71; 95%CI 1.01–2.68, P = 0.02). Conclusion: In-hospital delay of surgery (> 8 h) in patients with complicated appendicitis is associated with a higher risk of a postoperative complication. It is important that we recognize and treat these patients early. [ABSTRACT FROM AUTHOR]

Purpose: For the diagnosis of acute appendicitis, the combination of clinical and laboratory variables achieves high diagnostic accuracy. Nevertheless, appendicitis can present with normal laboratory tests of inflammation. The aim of this study was to investigate the incidence of normal inflammatory markers in patients operated for acute appendicitis. Methods: This is an analysis of data from a prospective, multicentre SNAPSHOT cohort study of patients with suspected acute appendicitis. Only patients with histopathologically proven acute appendicitis were included. Adult patients with acute appendicitis and normal preoperative inflammatory markers were explored further in terms of abdominal complaints, preoperative imaging results and intraoperative assessment of the degree of inflammation and compared to those with elevated inflammatory markers. Results: Between June and July 2014, 1303 adult patients with histopathologically proven acute appendicitis were included. In only 23 of 1303 patients (1.8%) with proven appendicitis, both preoperative white blood cell count and C-reactive protein levels were normal. Migration of pain was reported less frequently in patients with normal inflammatory markers compared to those with elevated inflammatory marker levels (17.4% versus 43.0%, p = 0.01). Characteristics like fever, duration of symptoms and localized peritonitis were comparable. Only 4 patients with normal inflammatory markers (0.3% overall) had complicated appendicitis at histopathological evaluation. Conclusion: Combined normal WBC and CRP levels are seen in about 2 per 100 patients with confirmed acute appendicitis and can, although rarely, be found in patients with complicated appendicitis.

Introduction: In patients treated with an appendectomy for acute appendicitis, the specimen is generally sent for histological evaluation. In an era of increasing non-operative treatment for acute appendicitis, it is important to know the incidence, the diagnostic accuracy, and treatment consequences of appendicular neoplasms that are found in acute appendicitis. We hypothesize that pre- and intra-operative parameters might predict an appendicular neoplasm. Methods: Data was used from our previous prospective observational cohort study. All patients undergoing surgery for suspected acute appendicitis were included. The primary outcome was the incidence of appendicular neoplasms in patients operated for acute appendicitis. Secondary outcomes were pre-operative diagnostics and imaging outcomes, intra-operative surgical judgment, and postoperative management and outcome. Possible predictors of an appendicular neoplasm were identified and used in multivariable logistic regression. Patients with an appendicular neoplasm were followed for 3 years after initial appendectomy. Results: A total of 1975 patients underwent surgery for suspected acute appendicitis and in 98.3% (1941/1975) the appendix was removed. In 1.5% (30/1941) of these patients, an appendicular neoplasm was found. Among the malignant neoplasms, the majority were grade 1 neuroendocrine tumors (NET) in 65% (13/20). On pre-operative imaging, there was no suspicion of malignancy. In three cases, there was an intra-operative suspicion of malignancy. Multivariable analysis showed only age as an independent predictor for appendicular neoplasms. No recurrent or new malignancy was found during follow-up. Discussion: The incidence of appendicular neoplasm in patients undergoing an acute appendectomy is very low and clinical risk factors could not be identified. [ABSTRACT FROM AUTHOR]

Purpose: To identify discrepancies between intraoperative and histological evaluations of the appendix in acute appendicitis and to evaluate the effect on surgical outcome.Methods: Data was used from our previous multicentre, prospective, cohort study of patients with suspected acute appendicitis. Appendices were scored during intraoperative and histological evaluation as uncomplicated or complicated appendicitis. Primary outcome was percentage of concordance between intraoperative and histological evaluation. Secondary outcomes were (infectious) postoperative complications, length of hospital stay, hospital re-admission and re-intervention rate, all within 30 days of surgery.Results: A total of 1850 patients were included. In 65.7% (1215/1850) of the appendices, the intraoperative evaluation was uncomplicated and in 34.3% (635/1850), complicated appendicitis. Patients with uncomplicated appendicitis had a postoperative course with significantly less postoperative complications (7.2% vs 24.3%), a shorter length of hospital stay (2 vs 5 days) and a lower re-admission (4.2% vs 9.6%) and re-intervention rate (1.1% vs 4.3%) than intraoperative complicated appendicitis (p < 0.001). In 93.5% (1136/1215) of the intraoperative uncomplicated patients and in 46.6% (296/635) of the intraoperative complicated patients, there was an agreement with pathology (Kappa 0.45). In 23.9% (81/339) of patients with intraoperative complicated and histological uncomplicated appendicitis, a postoperative complication was observed, which was similar to the postoperative complication rate of complicated appendicitis both on intraoperative and histological evaluation (24.7% (73/296)).Conclusions: There is a moderate agreement between a surgeon and pathologist in diagnosing patients with complicated appendicitis. However, the intraoperative diagnosis of complicated appendicitis was significantly associated with postoperative complications. Routine histological evaluation should be preserved for excluding malignancies in suspect appendices. [ABSTRACT FROM AUTHOR]

Background: Studies comparing laparoscopic and open appendicectomy are difficult to interpret owing to several types of bias, and the results often seem of limited clinical importance. National audits can be valuable to provide insight into outcomes following appendicectomy at a population level. Methods: A prospective, observational, resident-led, nationwide audit was carried out over a period of 2months, including all consecutive adult patients who had surgery for suspected acute appendicitis. Complications after laparoscopic and open appendicectomy were compared by means of logistic regression analysis; subgroup analyses were performed for patients with complicated appendicitis. Results: A total of 1975 patients were included from 62 participatingDutch hospitals. A normal appendix was seen in 3.3 per cent of patients. Appendicectomy was performed for acute appendicitis in 1378 patients, who were analysed. All but three patients underwent preoperative imaging. Laparoscopy was used in 79.5 per cent of patients; the conversion ratewas 3.4 per cent. A histologically normal appendixwas found in 2.2 per cent. Superficial surgical-site infection was less common in the laparoscopic group (odds ratio 0.25, 95 per cent c.i. 0.14 to 0.44; P <0.001). The rate of intra-abdominal abscess formation was not significantly different following laparoscopic or open surgery (odds ratio 1.71, 0.80 to 3.63; P =0.166). Similar findings were observed in patients with complicated appendicitis. Conclusion: Management of acute appendicitis in the Netherlands is preferably performed laparoscopically, characterized by a low conversion rate. Fewer superficial surgical-site infections occurred with laparoscopy, although the rate of abscess formation was no different from that following open surgery. A low normal appendix rate is the presumed effect of a mandatory preoperative imaging strategy. [ABSTRACT FROM AUTHOR]

Objectives: To investigate the effectiveness of bipolar radiofrequency-induced thermal therapy (RFITT) in a multicentre non-randomized study. Methods: Some 672 incompetent saphenous veins (85% great saphenous varicose vein, 15% short saphenous vein) in 462 patients (56.5% CEAP [clinical, aetiological, anatomical and pathological elements] class 3 or worse) were treated in eight European centres. Patients were assessed between 180 and 360 days postoperatively. Occlusion rates were determined by duplex ultrasound and compared with the power used for treatment, pull back rate and experience of the operating surgeon. Results: Complete occlusion rates of 98.4% were achieved when treatments were performed by an experienced operator (more than 20 cases), when the maximum power setting on the RFITT generator was between 18 and 20W and the applicator was withdrawn at a rate slower than 1.5 second/cm Conclusions: RFITT is efficacious, well tolerated by patients and has a low incidence of procedure-related post-operative complications.
