Delayed laparoscopic peritoneal washout in non-operative management of blunt abdominal trauma: a scoping review.

OBJECTIVES: Non-operative management (NOM) of blunt abdominal trauma has become increasingly common in hemodynamically stable patients. There are known complications of NOM from undrained intra-abdominal fluid accumulations including hemorrhage and peritonitis that require delayed operation. Thus, delayed operation can be considered as part of the overall management plan, instead of failure, of NOM. The aim of this scoping review is to establish key concepts regarding delayed laparoscopic peritoneal washout (DLPW) following NOM of blunt abdominal trauma patients. METHODS: MEDLINE, EMBASE, CENTRAL, and gray literature were systematically searched. Studies were included if they investigated or reported on the use of delayed laparoscopy involving peritoneal washout following NOM of blunt abdominal trauma patients. Bibliographies of included studies were manually reviewed to identify additional articles for inclusion. RESULTS: From 910 citations, 28 studies met inclusion criteria. This included seven case reports, eleven case series or observational cohort studies, six review articles, two management guidelines, one textbook chapter, and one randomized clinical trial. For those reported, medium grade liver injuries proved most common (95.2%). Indications for DLPW were primarily clinical features and changes in imaging findings, highlighting the importance of close observation. Authors reported clinical improvement after DLPW regarding symptomatology, vital signs, and biochemistry. A relatively high transfusion demand was reported with a mean of four units of packed red blood cells pre-operatively. Length of stay and post-operative complications were consistent with previously reported experiences with blunt abdominal injuries. CONCLUSIONS: DLPW is beneficial in blunt abdominal trauma patients following NOM with improvement in symptoms, SIRS features, and a possible reduction in hospital length of stay. This study is limited by low-quality evidence and skewing of data toward isolated hepatic injuries. Future prospective cohort study comparing NOM with and without DLPW is required.

A population-based cohort examining factors affecting all-cause morbidity and cost after pediatric appendectomy: Does annual adult procedure volume matter?

BACKGROUND: The purpose of this study was to examine factors affecting morbidity and cost after pediatric appendectomy and particularly the role of adult surgical volume. MATERIALS AND METHODS: This was population-based study including all pediatric patients who underwent appendectomy for appendicitis in Canada (excluding Quebec) from 2008 to 2015. All-cause morbidity was the main outcome of interest. Cost of the index admission (in 2014 Canadian dollars) was a secondary outcome. Hierarchal linear and logistic regressions were used to model the outcomes. RESULTS: Overall, 41,512 patients were identified. After adjustment, younger patients (OR = 0.98/year, 95%CI 0.97-0.99, p < 0.001), patients with comorbidities (OR = 2.20, 95%CI 1.96-2.46, p < 0.001), and those with perforated appendicitis (OR = 5.95, 95%CI 5.44-6.50, p < 0.001) were more susceptible to morbidity. Annual pediatric appendectomy volume was a significant predictor of reduced morbidity (OR = 0.85/20 cases, 95%CI 0.76-0.93, p < 0.001) as was the use of laparoscopy (OR = 0.81, 95%CI 0.72-0.91, p = 0.001). Conversely, annual adult appendectomy volume conferred no benefit nor did pediatric surgery specialty training. CONCLUSION: Outcomes after pediatric appendectomy are influenced by pediatric case volume, regardless of specialty training, but extra adult surgical volume confers no benefit.

Factors Associated With Outcomes and Costs After Pediatric Laparoscopic Cholecystectomy.

Importance: The prevalence of pediatric cholelithiasis is increasing with the epidemic of childhood obesity. With this rise, the outcomes and costs of pediatric laparoscopic cholecystectomy become an important public health and economic concern. Objective: To assess patient and health system factors associated with the outcomes and costs after laparoscopic cholecystectomy among Canadian children. Design, Setting, and Participants: This was a retrospective, population-based study of children 17 years and younger undergoing laparoscopic cholecystectomy from April 1, 2008, until March 31, 2015. The data source was the Canadian Institute for Health Information. The Canadian Institute for Health Information Discharge Abstract Database includes data from all Canadian hospitals. The analysis was limited to inpatient cholecystectomies. All Canadian children undergoing laparoscopic cholecystectomy were included. Exposure: The exposure in this study was laparoscopic cholecystectomy. Main Outcomes and Measures: The primary outcome was all-cause morbidity, a composite outcome of any complication that prolonged length of stay by 24 hours or required a second, unplanned procedure. The cost of the index admission was also calculated as a secondary outcome. These outcomes of interest were determined before data analysis. Odds ratios and 95% CIs were estimated using multilevel logistic regression models. Results: During the study period, 3519 laparoscopic cholecystectomies were performed; of these, 79.1% (n = 2785) were in girls, and 98.0% (n = 3450) were for gallstone disease. The overall morbidity rate was 3.9% (n = 137). After adjustment, patients with comorbidities were more susceptible to morbidity (odds ratio, 2.68; 95% CI, 1.78-3.86; P < .001). Operations for gallstones were less morbid. High-volume general surgeons had lower morbidity rates compared with low-volume pediatric surgeons (odds ratio, 0.32; 95% CI, 0.12-0.69; P = .005) independent of pediatric volumes. The mean (SD) unadjusted cost of a laparoscopic cholecystectomy was $4115 ($7273). Operative indication, complications, comorbidities, emergency admission, and surgeon volume were associated with cost. Conclusions and Relevance: The high-volume nature of adult general surgery translated to lower morbidity and cost after pediatric laparoscopic cholecystectomy, suggesting that adult volume is associated with pediatric outcomes. As the rate of pediatric gallstone disease increases, surgeon volume, rather than specialty training, should be considered when pursuing operative management.

Sedentary Time and Screen-Based Sedentary Behaviors of Children With a Chronic Disease.

The objectives of this study were to (i) assess sedentary time and prevalence of screen-based sedentary behaviors of children with a chronic disease and (ii) compare sedentary time and prevalence of screen-based sedentary behaviors to age- and sex-matched healthy controls. Sixty-five children (aged 6-18 years) with a chronic disease participated: survivors of a brain tumor, hemophilia, type 1 diabetes mellitus, juvenile idiopathic arthritis, cystic fibrosis, and Crohn's disease. Twenty-nine of these participants were compared with age- and sex-matched healthy controls. Sedentary time was measured objectively by an ActiGraph GT1M or GT3× accelerometer worn for 7 consecutive days and defined as less than 100 counts per min. A questionnaire was used to assess screen-based sedentary behaviors. Children with a chronic disease engaged in an average of 10.2 ± 1.4 hr of sedentary time per day, which comprised 76.5 ± 7.1% of average daily monitoring time. There were no differences between children with a chronic disease and controls in sedentary time (adjusted for wear time, p = .06) or in the prevalence of TV watching, and computer or video game usage for varying durations (p = .78, p = .39 and, p = .32 respectively). Children with a chronic disease, though relatively healthy, accumulate high levels of sedentary time, similar to those of their healthy peers.

Performance of children on the Community Balance and Mobility Scale.

This study describes the performance of children 8-11 years of age on the Community Balance and Mobility Scale (CB&M) and associations between performance and age, body mass index (BMI), and sex. A convenience sample of 84 was recruited. The CB&M was administered using instructions we developed for children. Mean CB&M total scores (95% confidence intervals) for age groups were 8: 70.1 (64.2, 76.1); 9: 72.8 (68.7, 76.8); 10: 79.2 (76.6, 81.7); and 11: 82.9 (79.2, 86.5). None of the children achieved the maximum score. Scores increased with age, and overweight/obese children had relatively lower scores. There were no significant differences between males and females. A regression analysis found 28.1% of the variation in the CB&M total scores was explained by age (p < .001), BMI (p < .01), and sex (p = .25) suggesting that other factors contribute to variation in balance and mobility proficiency. The modified instructions and scoring patterns from this study can assist in using the CB&M in children of ages 8-11 years.
