Clinical and Economic Implications of Interventions in Pancreatic Fluid Collections: An Assessment From a National Claims Database.

OBJECTIVE: To compare clinical and economic implications of percutaneous and endoscopic treatment approaches in patients with pancreatic fluid collections (PFCs). MATERIALS AND METHODS: This is a retrospective claims analysis of Medicare beneficiaries who underwent inpatient endoscopic or percutaneous PFC drainage procedures (2016-2020). We performed longitudinal analysis of claims for all-cause mortality and rehospitalization during 180-day follow-up. Main outcome was mortality. Other outcomes were rehospitalization and direct costs. RESULTS: A total of 1311 patients underwent endoscopic (n = 727) or percutaneous (n = 584) drainage. Percutaneous as compared with endoscopic approach was associated with higher mortality (23.08% vs 16.7%, P = 0.004), rehospitalization (58.9% vs 53.3%, P = 0.04), and mean direct hospital costs ($37,107 [SD = $67,833] vs $27,800 [SD = $43,854], P = 0.004). On multivariable analysis, percutaneous drainage (adjusted hazard ratio [HR], 1.38; 95% confidence interval [CI], 1.02-1.86; P = 0.039), older age (hazard ratio [HR], 1.04; 95% CI, 1.01-1.04; P < 0.001), intensive care unit stay (HR, 1.02; 95% CI, 1.01-1.03; P < 0.001), and multiple comorbidities (HR, 1.07; 95% CI, 1.05-1.09; P < 0.001) were significantly associated with mortality. Percutaneous drainage (adjusted odds ratio [OR], 1.30; 95% CI, 1.04-1.63; P = 0.027) and older age (OR, 0.98; 95% CI, 0.97-0.99; P < 0.001) were significantly associated with rehospitalizations. CONCLUSIONS: As percutaneous drainage may be associated with higher mortality, rehospitalization, and costs, when requisite expertise is available, endoscopy should be preferred for treatment of PFC amenable to such an approach. Randomized trials are required to validate these findings.

Resource Use and Costs of Indwelling Pleural Catheters versus Pleurodesis for Malignant Pleural Effusions: A Population-based Study.

Rationale: Malignant pleural effusions (MPEs) are associated with significant health service use and healthcare costs, but the current evidence is limited. Objectives: To compare 12-month post-procedure: 1) health service utilization; and 2) healthcare costs after indwelling pleural catheter (IPC) insertion with at-home drainage performed by home care nursing services, versus in-hospital chemical pleurodesis. Methods: We performed a retrospective population-based study on a cohort of adults with MPEs who underwent IPC insertion or chemical pleurodesis between January 1, 2015 and December 31, 2019 using provincial health administrative data (Ontario, Canada). Patients were followed from the procedure date until death or until 12 months after the procedure. Inverse probability of treatment weighting was performed to adjust for imbalances in baseline characteristics. Differences in length of stay, readmissions, emergency department visits, home care visits, and healthcare costs were estimated using weighted regression analysis. Results: Of 5,752 included individuals, 4,432 (77%) underwent IPC insertion and 1,320 (23%) had pleurodesis. In the weighted sample, individuals who received an IPC had fewer inpatient days (12.4 d vs. 16 d; standardized mean difference, 0.229) but a higher proportion of subsequent admissions for empyema (2.7% vs. 1.1%; P = 0.0002) than those undergoing pleurodesis. Individuals with IPCs received more hours of nursing home care (41 h vs. 21.1 h; standardized mean difference, 0.671) but overall had lower average healthcare costs ($40,179 vs. $46,640 per patient; standardized mean difference, 0.177) than those receiving pleurodesis. Conclusions: IPCs with home nursing drainage are associated with reduced health resource use compared with pleurodesis in adults with MPEs, even after controlling for important baseline and clinical characteristics. Given that both procedures have similar health outcomes, our findings support the ongoing promotion of IPCs to increase outpatient management of patients with MPEs.

The Efficiency of Laparoscopic Common Bile Duct Exploration in Endoscopic Retrograde-Cholangiopancreatography-Limited Setting in a Peripheral University Hospital.

Background: The aim of this study is to evaluate complications and costs in patients treated with laparoscopic and open method for common bile duct (CBD) stones. Secondary aim is to compare the effectiveness, safety, and outcomes of these methods. In addition, it is aimed to review the feasibility of laparoscopic method in rural areas. Methods: Seventy-one patients were analyzed retrospectively. Patients were divided into two groups as open and laparoscopic surgical method. These groups were analyzed comparatively in terms of complications and costs. Subgroups were formed from patients who underwent T-tube drainage, primary closure, and biliary anastomosis as choledochotomy management. As a secondary outcome, these three subgroups were investigated in terms of complications and cost. Results: The cost was lower in open method compared to laparoscopic method (484$, 707$, P = .002). There was no significant difference in postoperative complications between groups (P = .257). While the mean hospital stay was longer in the open group, the operation time was shorter (P = .002, P = .03). The mean length of hospital stay in the T-tube group was significantly higher than the primary closure (P = .001). The cost in the T-tube group was significantly higher than the primary closure and biliary anastomosis groups. Conclusion: Laparoscopic CBD exploration by experienced surgeons in endoscopic retrograde-cholangiopancreatography-limited settings is an effective and safe method in the treatment of choledocholithiasis. This procedure should not be limited to reference centers and should be performed safely in rural areas by well-trained surgeons.

Endoscopic Transpapillary Gallbladder Drainage for Acute Cholecystitis.

The mainstay of management of acute cholecystitis has been surgical, with percutaneous gallbladder drainage in patients deemed high risk for surgical intervention. Endoscopic management of acute cholecytitis with transpapillary and transmural drainage of the gall bladder is emerging as a viable alternative in high-risk surgical patients. In this article, we discuss the background, current status, technical challenges and strategies to overcome them, adverse events, and outcomes of endoscopic transpapillary gallbladder drainage for management of acute cholecystitis.

Minimally invasive and inexpensive percutaneous abscess drainage using an indwelling needle cannula.

PURPOSE: Abscess is still a formidable disease and requires adequate drainage. Moreover, drainage in the head and neck area needs cosmetic care, especially in the pediatric population. In this report, we introduce our method of percutaneous abscess drainage using an indwelling needle cannula. PATIENTS AND METHODS: Ten pediatric and five adult patients with cervical and/or facial abscess treated with this drainage method were retrospectively reviewed. Using an indwelling needle cannula (18-14 G Surflow®, Terumo, Tokyo, Japan), abscesses were penetrated under ultrasonic examination. Once purulent retention was identified, the inner metal needle was removed and the outer elastic needle was left and fixed. The outer needle was connected to the tube for continuous suction drainage for large abscess. RESULTS: The primary diseases of these abscesses were cervical abscess of dental origin (5), purulent lymphadenitis (3), pyriform sinus fistula (2) and subperiosteal abscess due to mastoiditis (2), circumorbital cellulitis (1), infection of Warthin's tumor (1), and unknown origin (1). The median (range) duration of drainage was 4 days (3-9 days). Abscesses were successfully treated, and no patients required additional incision for abscess drainage. No apparent scars after drainage were observed. CONCLUSION: This technique resembles the usual venous placement of an indwelling needle cannula and is thought to be familiar to physicians. Although simple and inexpensive, this drainage is safe, effective, and minimally invasive for the treatment of abscess.

A simple and cost-effective model for ventricular catheter placement training: technical note.

OBJECTIVE: External ventricular drain (EVD) placement is one of first cranial procedures neurosurgery residents are expected to perform independently. While proper training improves patient outcomes, there are few options for practicing EVD placement prior to placing the EVD in patients in a clinical setting. Proposed solutions to this include using cadaveric models and virtual simulations, but barriers exist with these as well in regard to authenticity. EVD simulators using virtual reality technologies are a promising new technique for training, but the cost of these devices poses a barrier to general/widespread accessibility among smaller programs or underserved hospitals. The authors desribe a novel, yet simple, and cost-effective technique (less than $5 per mold) for developing a brain model constructed of homemade ballistics gelatin that can be used for teaching and practicing the placement of EVD. METHODS: A brain model is made with ballistics gelatin using an anatomically correct skull model as a mold. A 3D-printed ventricular system model is used to create a mold of an anatomically correct ventricular system in the brain model. A group of medical students (n = 10) were given a basic presentation about EVD placement, including standard landmarks and placement techniques, and were also shown a demonstration of EVD placement on the brain model. They were then allowed to perform an EVD placement using the brain model. The students were surveyed on their experience with using the brain model, including usability and practicality of the model. Accuracy of EVD placement by each student was also assessed, with adequate position of catheter tip being in the ipsilateral frontal horn. RESULTS: The final product is fairly inexpensive and easy to make. It is soft enough to pass a catheter through, but it is also firm enough to maintain its shape, including a cavity representing the lateral ventricles. The dense gelatin holds the catheter in its final resting position, while the two halves are separated and inspected. All participants in the test group of medical students reported that the brain model was easy to use, helped them understand the steps and technique of EVD placement, and provided good feedback on the ideal position of ventricular catheters. All of the participants in the group had adequate positioning of their ventricular catheters after one attempt. CONCLUSIONS: The presented brain model is easy to replicate, inexpensive, anatomically accurate, and provides a medium for neurosurgeons to teach and practice ventricular catheter placement in a risk-free environment.

Hospital care pathway of women treated for Bartholin's gland abscess and budget impact analysis of outpatient management: A national hospital database analysis.

INTRODUCTION: Bartholin's gland abscesses cause severe pain and are a source of frequent emergency room visits. The most widespread treatment in France is incision-drainage during hospitalisation. A Word catheter, whose efficiency and safety would be identical, could be used without the need for hospitalisation, thus reducing the costs of Bartholin's gland abscess management. DESIGN: Retrospective cohort study. SETTING: French hospital (PMSI) database 2016-2017. POPULATION: 3539 women with Bartholin's gland abscess. METHOD: From the PMSI database, we identified the population that was treated for incision-drainage of a Bartholin's gland abscess in 2016. We also looked for secondary hospitalisations occurring within 12 months of initial treatment of Bartholin's gland abscess using 2016 and 2017 PMSI database data. MAIN OUTCOME(S): The identified population was described in terms of age, hospitalisation, length of stay and readmissions within 12 months and provided a 5-year budget impact analysis of the use of the Word catheter in France from a National Health Insurance perspective. RESULTS: In 2016, 3539 women (36 +/- 11.8 years) were hospitalised for 3646 incisions of the major vestibular gland linked to a Bartholin's gland abscess. 11.38 % (403/3,539) underwent at least one new Bartholin's gland procedure during the following year. The use of the Word catheter would allow potential savings over 5 years of €7.4 million. CONCLUSION: The use of the Word catheter could be cost-saving. These results must be validated by a clinical research step evaluating efficiency in the French context, comparing the Word catheter and incision-drainage side-by-side.

Active clearance of chest tubes is associated with reduced postoperative complications and costs after cardiac surgery: a propensity matched analysis.

BACKGROUND: Chest tubes are routinely used to evacuate shed mediastinal blood in the critical care setting in the early hours after heart surgery. Inadequate evacuation of shed mediastinal blood due to chest tube clogging may result in retained blood around the heart and lungs after cardiac surgery. The objective of this study was to compare if active chest tube clearance reduces the incidence of retained blood complications and associated hospital resource utilization after cardiac surgery. METHODS: Propensity matched analysis of 697 consecutive patients who underwent cardiac surgery at a single center. 302 patients served as a baseline control (Phase 0), 58 patients in a training and compliance verification period (Phase 1) and 337 were treated prospectively using active tube clearance (Phase 2). The need to drain retained blood, pleural effusions, postoperative atrial fibrillation, ICU resource utilization and hospital costs were assessed. RESULTS: Propensity matched patients in Phase 2 had a reduced need for drainage procedures for pleural effusions (22% vs. 8.1%, p < 0.001) and reduced postoperative atrial fibrillation (37 to 25%, P = 0.011). This corresponded with fewer hours in the ICU (43.5 [24-79] vs 30 [24-49], p = < 0.001), reduced median postoperative length of stay (6 [4-8] vs 5 [4-6.25], p < 0.001) median costs reduced by $1831.45 (- 3580.52;82.38, p = 0.04) and the mean costs reduced by an average of $2696 (- 6027.59;880.93, 0.116). CONCLUSIONS: This evidence supports the concept that efforts to actively maintain chest tube patency in early recovery is useful in improving outcomes and reducing resource utilization and costs after cardiac surgery.

Economics of Lymphovenous Bypass.

BACKGROUND: The objective of this study was to compare the economic impact of complete decongestive therapy and lymphovenous bypass in the management of upper extremity lymphedema. METHODS: Economics were modeled for a patient with breast cancer-related lymphedema undergoing three different clinical pathways: (1) complete decongestive therapy alone; (2) lymphovenous bypass no longer requiring ongoing complete decongestive therapy; or (3) lymphovenous bypass requiring ongoing complete decongestive therapy. Activity-based cost analysis identified costs incurred with complete decongestive therapy and lymphovenous bypass. Costs were retrieved from supplier price lists, physician fee schedules, lymphedema therapists, and literature reviews. The net present value of all costs incurred for each clinical pathway were calculated. RESULTS: The estimated net present value of all costs for a patient with breast cancer-related lymphedema undergoing treatment were as follows: (1) complete decongestive therapy alone ($30,400); (2) lymphovenous bypass no longer requiring ongoing complete decongestive therapy ($15,000); or (3) lymphovenous bypass requiring ongoing complete decongestive therapy ($42,100). The expected net present value of all costs for lymphovenous bypass was $26,800, which was comparable to that of complete decongestive therapy alone. Sensitivity analysis demonstrated that the expected net present value of lymphovenous bypass was dependent on the patient's life expectancy, number of bypass anastomoses, and likelihood of discontinuing complete decongestive therapy. CONCLUSIONS: Lymphedema has substantial ongoing costs irrespective of the treatment modality. The cost of lymphovenous bypass appears comparable to that of complete decongestive therapy alone-the surgical costs of lymphovenous bypass are offset by the savings from discontinued ongoing therapy. Despite its limitations as a theoretical economic model, this study provides insight into the potential economic impact of lymphovenous bypass.

Incremental Cost-Effectiveness of Aspiration Therapy vs Bariatric Surgery and No Treatment for Morbid Obesity.

INTRODUCTION: Despite its recent approval by the US Food and Drug Administration and Health Canada, aspiration therapy-one of the latest weight loss treatments-remains controversial. Critics have expressed concerns that the therapy could lead to bulimia and other binge eating disorders. Meanwhile, proponents argue that the therapy is less invasive, reversible, and cheaper than bariatric surgery. Cost-effectiveness of this therapy, however, is not yet established. METHODS: We developed a Markov model to estimate the incremental cost-effectiveness of aspiration therapy relative to 2 most common bariatric surgery procedures (gastric bypass and sleeve gastrectomy) and no treatment over a lifetime horizon. Costs were estimated from the health system's perspective using US data. Effectiveness was measured in terms of quality-adjusted life-years (QALYs). RESULTS: Despite being a cheaper procedure than bariatric surgery, aspiration therapy costs more than bariatric surgery in the long term because of its high maintenance costs (i.e., periodic replacement of device parts). It also yields lower QALYs than bariatric surgery because of its smaller weight loss effects. Thus, the therapy is dominated by bariatric surgery. In particular, compared with gastric bypass, it costs US$5,318 more and yields 1.31 fewer QALYs. However, aspiration therapy is cost-effective relative to no treatment with an incremental cost-effectiveness ratio of US$17,532 per QALY gained. DISCUSSION: Given its high lifetime costs and its modest weight loss effects, aspiration therapy is not cost-effective relative to bariatric surgery. However, it is a cost-effective treatment option for patients who lack access to bariatric surgery.

Cost effectiveness of endoscopic gallbladder drainage to treat acute cholecystitis in poor surgical candidates.

BACKGROUND: Endoscopic gallbladder drainage (GBD) is an alternative to percutaneous GBD (PGBD) to treat acute cholecystitis, yielding similar success rates and fewer adverse events. To our knowledge, no cost-effectiveness analysis has compared these procedures. We performed an economic analysis to identify clinical and cost determinants of three treatment options for acute cholecystitis in poor surgical candidates. METHODS: We compared three treatment strategies: PGBD, endoscopic retrograde cholangiographic transpapillary drainage (ERC-GBD), and endosonographic GBD (EUS-GBD). A decision tree was created over a 3-month period. Effectiveness was measured using hospital length of stay, including adverse events and readmissions. Costs of care were calculated from the National Inpatient Sample. Technical and clinical success estimates were obtained from the published literature. Cost effectiveness was measured as incremental cost effectiveness and compared to the national average cost of one hospital bed per diem. RESULTS: Analysis of a hypothetical cohort of poor candidates for cholecystectomy showed that, compared to PGBD, ERC-GBD was a cost-saving strategy and EUS-GBD was cost effective, requiring $1312 per hospitalization day averted. Additional costs of endoscopic interventions were less than the average cost of one hospital bed per diem. Compared to ERC-GBD, EUS-GBD required expending an additional $8950 to prevent one additional day of hospitalization. Our model was considerably affected by lumen-apposing metal stent cost and hospital length of stay for patients managed conservatively and those requiring delayed surgery. CONCLUSIONS: Endoscopic GBD is cost effective compared to PGBD, favoring ERC-GBD over EUS-GBD. Further efforts are needed to make endoscopic GBD available in more medical centers, reduce equipment costs, and shorten inpatient stay.

Chest tube removal algorithm is associated with decreased chest tube duration in pediatric cardiac surgical patients.

OBJECTIVE: Management of chest tubes in adult and pediatric patients is highly variable. There are no published guidelines for pediatric cardiac surgical patients. Our center undertook a quality improvement project aimed at reducing chest tube duration and length of stay in postsurgical pediatric cardiac patients. METHODS: A work group identified 2 opportunities for reducing chest tube duration: standardizing removal criteria and increasing frequency of assessment for removal. An algorithm was created, and chest tube assessments were increased to twice daily. All postsurgical cardiac patients were managed according to the algorithm. Outcome measure reporting was limited to patients age 1 month to 18 years with a biventricular surgical procedure. Outcome measures included chest tube duration, cardiac intensive care unit and hospital length of stay, and cost of hospitalization. Process measure was documentation of chest tube assessments. The balancing measure was chest tube reinsertions. RESULTS: Between April 2016 and July 2018, 126 patients aged 1 month to 18 years underwent a biventricular surgical procedure. Mean chest tube duration decreased from 61 to 47 hours. Cardiac intensive care unit length of stay decreased from 141 hours to 89 hours, hospital length of stay decreased from 266 to 156 hours, and average hospitalization cost decreased from $75,881 to $48,118. There was no increase in chest tube reinsertions. CONCLUSIONS: Implementation of a chest tube removal algorithm for pediatric cardiac surgery patients resulted in decreased chest tube duration and was associated with decreased length of stay and costs without an increase in reinsertions. More significant impact may be attainable with more aggressive approach to removal.

Non-Operative Management is More Cost-Effective than Immediate Operation in Perforated Appendicitis Patients with Seven or More Days of Symptoms.

BACKGROUND: Management of perforated appendicitis in children remains controversial. Nonoperative (NO) and immediate operative (IO) strategies are used with varying outcomes. We hypothesized that IO intervention for patients with perforated appendicitis would be more cost-effective than NO management. METHODS: A retrospective chart review of all patients with appendicitis from 2012 to 2015 was performed. Patients with perforated appendicitis were defined by evidence of perforation on imaging. We excluded patients who presented with sepsis, organ failure, and ventriculoperitoneal shunts. NO management was determined by surgeon preference. Univariate and multivariate analyses were performed. RESULTS: IO was performed on 145 patients with perforated appendicitis, whereas 83 were treated with NO management. Compared to IO patients, NO patients incurred higher overall costs, greater length of stay, more readmissions, complications, peripherally inserted central venous catheter lines, interventional radiology drains, and unplanned clinic and emergency department visits (P < 0.0001 for all). Multivariate analysis adjusting for age, days of symptoms, admission C-reactive protein and white blood cell count revealed that NO management was independently associated with increased costs (OR 1.35, 1.12-1.62, 95% CI). Cost curves demonstrated that total cost for IO surpasses that of NO management when patients present with greater than 6.3 d of symptoms (P = 0.01). CONCLUSIONS: Our data suggest that IO is more cost-effective than NO management for patients with perforated appendicitis who present with less than 6.3 d of symptoms, after which point, NO management is more cost-effective. LEVEL OF EVIDENCE: IV.

Endoscopic versus surgical treatment for pancreatic pseudocysts: Systematic review and meta-analysis.

OBJECTIVE: This systematic review and meta-analysis aims to compare surgical and endoscopic treatment for pancreatic pseudocyst (PP). METHODS: The researchers did a search in Medline, EMBASE, Scielo/Lilacs, and Cochrane electronic databases for studies comparing surgical and endoscopic drainage of PP s in adult patients. Then, the extracted data were used to perform a meta-analysis. The outcomes were therapeutic success, drainage-related adverse events, general adverse events, recurrence rate, cost, and time of hospitalization. RESULTS: There was no significant difference between treatment success rate (risk difference [RD] -0.09; 95% confidence interval [CI] [0.20,0.01]; P = .07), drainage-related adverse events (RD -0.02; 95% CI [-0.04,0.08]; P = .48), general adverse events (RD -0.05; 95% CI [-0.12, 0.02]; P = .13) and recurrence (RD: 0.02; 95% CI [-0.04,0.07]; P = .58) between surgical and endoscopic treatment.Regarding time of hospitalization, the endoscopic group had better results (RD: -4.23; 95% CI [-5.18, -3.29]; P < .00001). When it comes to treatment cost, the endoscopic arm also had better outcomes (RD: -4.68; 95% CI [-5.43,-3.94]; P < .00001). CONCLUSION: There is no significant difference between surgical and endoscopic treatment success rates, adverse events and recurrence for PP. However, time of hospitalization and treatment costs were lower in the endoscopic group.

Safety, Accuracy, and Cost Effectiveness of Bedside Bolt External Ventricular Drains (EVDs) in Comparison with Tunneled EVDs Inserted in Theaters.

OBJECTIVES: External ventricular drain (EVD) placement is required frequently in neurosurgical patients to divert cerebrospinal fluid and monitor intracranial pressure. The usual practice is the tunneled EVD technique performed in operating theaters. EVD insertion through a bolt in intensive care also is described. We employ both practices in our institute. Herein, we compare the indications, accuracy, safety, and costs of the 2 techniques. METHODS: This was a retrospective cohort study of a prospectively maintained EVD database of all patients undergoing first frontal EVD placement between January 2010 and December 2015. Those patients with preceding cerebrospinal fluid infection were excluded. We compared bolt EVD with tunneled EVD techniques in terms of accuracy of EVD tip location by analyzing computed tomography scans to grade catheter tip location as optimal (ipsilateral frontal horn) or otherwise suboptimal, and complications that include infection and revision rates. RESULTS: In total, 579 eligible patients aged 3 months to 84 years were identified; 430 had tunneled EVDs and 149 bolt EVDs. The most frequent diagnosis was intracranial hemorrhage (73% bolt vs. 50.4% tunneled group; P < 0.001). Other diagnoses included tumor (4.7% bolt vs. 19.1% tunneled; P < 0.001) and traumatic brain injury (17.5% bolt vs. 17.4% tunneled). In the bolt EVD group 66.4% of EVD tips were optimal, compared with 61.0% in the tunneled group (P = 0.33). Infection was confirmed in 15 (10.0%) bolt EVDs compared with 61 (14.2%) tunneled EVDs (P = 0.2). Each bolt EVD kit costs £260, whereas placing a tunneled one in the theater costs £1316. CONCLUSIONS: Bedside bolt EVD placement is safe, accurate, and cost effective in selective patients with hemorrhage-related hydrocephalus.

Amoebic liver abscess: Outcomes of percutaneous needle aspiration vs drain placement in paediatric population.

OBJECTIVE: To compare the effectiveness of percutaneous catheter drain placement with percutaneous needle aspiration in terms of hospital stay, time to resolution of symptoms and cost of intervention performed. Methods: The retrospective cohort study was conducted at Aga Khan University Hospital, Karachi, and comprised data of patients with amoebic liver abscess from, January 2006 to December 2016 which was collected using non-probability purposeful sampling. Primary outcome included length of hospital stay, time to resolution of symptoms and cost of intervention. Secondary outcomes included development of complications, need for re-intervention and abscess resolution. SPSS 22 was used for data analysis. . Results: Of the 62 patients, 36(58%) underwent percutaneous needle aspiration Group A, and 26(42%) were treated with percutaneous catheter drain placement Group B. Both groups were malnourished and anaemic at presentation. Overall, 56(90.3%) patients had single abscess and 44(71%) had it in the right lobe. Mean duration of symptoms was less in Group B compared to Group A (11.2±4.5 versus 16.4±3.2 days). Mean abscess size was 6.13cm ± 9.75cm in Group A and 7.40cm ± 8.40cm in Group B. The mean length of hospital stay Group A was shorter than in Group B (p=0.047) with earlier resolution of symptoms (p=0.027). Conclusion: Both methods were found to be effective in treating amoebic liver abscess in children, but percutaneous needle aspiration was more effective.

Short-term outcomes associated with drain use in shoulder arthroplasties: a prospective, randomized controlled trial.

BACKGROUND: This study examined the immediate outcomes during the perioperative period associated with drains in the setting of total shoulder arthroplasty or reverse shoulder arthroplasty. We hypothesized that drain use would result in lower postoperative hemoglobin and hematocrit levels that would increase transfusion rates and longer hospital stays that would increase hospital costs. METHODS: The study prospectively randomized 100 patients (55% women; average age, 69.3 years) who underwent total shoulder arthroplasty or reverse shoulder arthroplasty to receive a closed-suction drainage device (drain group, n = 50) or not (control group, n = 50) at the time of wound closure. Basic demographic information and intraoperative and postoperative data were collected. RESULTS: The groups were similar with respect to basic patient demographics. Postoperatively, drains had no effect on transfusion rates or any perioperative complication (P > .715). There were also no significant differences in hemoglobin or hematocrit levels immediately after surgery or on postoperative day 1. On average, patients were discharged from the hospital 1.6 days and 2.1 days postoperatively in the control and drain groups, respectively (P = .124). The average cost associated for the control cohort's hospital stay was $35,796 ± $13,078 compared with $43,219 ± $24,679 for the drain cohort (P = .063). DISCUSSION: Drain use after shoulder arthroplasty had no appreciable difference on short-term perioperative outcomes, postoperative anemia, length of hospital stay, or cost. It is possible that the potential negative effects of postoperative drainage are blunted by the routine use of tranexamic acid.

Conscious Sedation for Pediatric Peritonsillar Abscess: Comparison of Anesthetic Approaches.

OBJECTIVE: To compare the efficacy, safety, and cost of incision and drainage (I&D) for pediatric patients with peritonsillar abscesses (PTAs) under conscious sedation (CS) versus unsedated (awake) and general anesthesia (GA). STUDY DESIGN: Case series with chart review. SETTING: Tertiary pediatric hospital. SUBJECTS AND METHODS: Records for all pediatric patients (<18 years) treated for PTAs in the emergency department from 2005 to 2015 were reviewed and stratified into awake, CS, and GA groups for comparison. The primary outcome measure was procedure tolerance, with secondary measures including return to the emergency department within 15 days, complications, and facility costs associated with treatment. RESULTS: A total of 188 patients were identified. The median age was 14 years (interquartile range, 9-16). Awake drainage with injected local anesthetic was used in 115 children; 62 underwent CS; and 11 underwent GA. Over 92% of the children tolerated I&D regardless of anesthesia, with no difference among groups ( P = .60). None of those who underwent I&D via CS returned to the emergency department within 15 days of the procedure, as compared with 5.2% for the awake group and 9.1% for the GA group ( P = .06). None in the GA or awake group had a complication associated with the procedure, as opposed to 9.6% in the CS group ( P = .02). Complications included apnea and dental trauma (2 children each) and transient hypotension and desaturation (1 each). Cost was highest in the GA group and lowest for the awake group ( P < .0001). CONCLUSION: CS for PTA I&D is a viable treatment option with tolerance and success similar to that of the awake and GA groups. Complications were observed for those who underwent CS, but they were manageable.

Development and Implementation of an Inexpensive, Easily Producible, Time Efficient External Ventricular Drain Simulator Using 3-Dimensional Printing and Image Registration.

BACKGROUND: External ventricular drain (EVD) placement is one of the most commonly performed procedures in neurosurgery, frequently by the junior neurosurgery resident. Simulators for EVD placement are often costly, time-intensive to create, and complicated to set up. OBJECTIVE: To describe creation of a simulator that is inexpensive, time-efficient, and simple to set up. METHODS: This simulator involves printing a hollow head using a desktop 3-dimensional (3D) printer. This head is registered to a commercially available image-guidance system. A total of 11 participants volunteered for this simulation module. EVD placement was assessed at baseline, after verbal teaching, and after live 3D view instruction. RESULTS: Accurate placement of an EVD on the right side at the foramen of Monro or the frontal horn of the lateral ventricle increased from 44% to 98% with training. Similarly, accurate placement on the left increased from 42% to 85% with training. CONCLUSION: During participation in the simulation, accurate placement of EVDs increased significantly. All participants believed that they had a better understanding of ventricular anatomy and that this module would be useful as a teaching tool for neurosurgery interns.
