Irrigation versus suction alone during laparoscopic appendectomy for perforated appendicitis: a prospective randomized trial.

BACKGROUND: The efficacy of irrigating the peritoneal cavity during appendectomy for perforated appendicitis has been debated extensively. To date, prospective comparative data are lacking. Therefore, we conducted a prospective, randomized trial comparing peritoneal irrigation to suction alone during laparoscopic appendectomy in children. METHODS: Children younger than 18 years with perforated appendicitis were randomized to peritoneal irrigation with a minimum of 500 mL normal saline, or suction only during laparoscopic appendectomy. Perforation was defined as a hole in the appendix or fecalith in the abdomen. The primary outcome variable was postoperative abscess. Using a power of 0.8 and alpha of 0.05, a sample size of 220 patients was calculated. A battery-powered laparoscopic suction/irrigator was used in all cases. Pre- and postoperative management was controlled. Data were analyzed on an intention-to-treat basis. RESULTS: A total of 220 patients were enrolled between December 2008 and July 2011. There were no differences in patient characteristics at presentation. There was no difference in abscess rate, which was 19.1% with suction only and 18.3% with irrigation (P = 1.0). Duration of hospitalization was 5.5 ± 3.0 with suction only and 5.4 ± 2.7 days with group (P = 0.93). Mean hospital charges was $48.1K in both groups (P = 0.97). Mean operative time was 38.7 ± 14.9 minutes with suction only and 42.8 ± 16.7 minutes with irrigation (P = 0.056). Irrigation was felt to be necessary in one case (0.9%) randomized to suction only. In the patients who developed an abscess, there was no difference in duration of hospitalization, days of intravenous antibiotics, duration of home health care, or abscess-related charges. CONCLUSIONS: There is no advantage to irrigation of the peritoneal cavity over suction alone during laparoscopic appendectomy for perforated appendicitis. The study was registered with clinicaltrials.gov at the inception of enrollment (NCT00981136).

A review: the role of high dose methylprednisolone in spinal cord trauma in children.

BACKGROUND: The use of steroids in traumatic spinal cord injury (SCI) in children is controversial. There is a paucity of literature on its usage. To help clarify recommendations on steroid use in children, we reviewed the current literature on the administration of high dose methylprednisolone (MP) use in traumatic spinal cord injuries with an emphasis in pediatric spinal cord trauma. METHODS: A retrospective review of the current literature on traumatic spinal cord injuries was conducted. Outcomes were critically reviewed from the National Acute Spinal Cord Injury Studies (NASCIS) II and III and Cochrane review; as well as, other randomized and retrospective studies. Papers describing objective neurological outcomes were only included. RESULTS: The outcomes of neurological improvement following steroid infusion have not been reproducible outside of the NASCIS and one single Japanese trial. High dose steroids significantly increase the risk of infections leading to prolonged hospital stay and ventilator dependence. CONCLUSION: Data from adult studies remains controversial with insufficient data to support administration of MP for treatment of traumatic spinal cord injuries. Randomized controlled trials are needed in the pediatric population to assess the advantages of steroid use after SCI in children. On the basis of the current evidence, the use of steroids in patients is associated with increased infectious risks and no neurological improvements.

Single incision versus standard 3-port laparoscopic appendectomy: a prospective randomized trial.

BACKGROUND: Laparoscopic appendectomy through a single umbilical incision is an emerging approach supported by several case series. However, to date, prospective comparative data are lacking. Therefore, we conducted a prospective, randomized trial comparing single site umbilical laparoscopic appendectomy to 3-port laparoscopic appendectomy. METHODS: After Internal Review Board approval, patients were randomized to laparoscopic appendectomy via a single umbilical incision or standard 3-port access. The primary outcome variable was postoperative wound infection. Using a power of 0.9 and an alpha of 0.05, 180 patients were calculated for each arm. Patients with perforated appendicitis were excluded. The technique of ligation/division of the appendix and mesoappendix was left to the surgeon's discretion. There were 7 participating surgeons dictated by the call schedule. All patients received the same preoperative antibiotics and postoperative management was controlled. RESULTS: There were 360 patients were enrolled between August 2009 and November 2010. There were no differences in patient characteristics at presentation. There was no difference in wound infection rate, time to regular diet, length of hospitalization, or time to return to full activity. Operative time, doses of narcotics, surgical difficultly and hospital charges were greater with the single site approach. Also, the mean operative time was 5 minutes longer for the single site group. CONCLUSION: The single site umbilical laparoscopic approach to appendectomy produces longer operative times resulting in greater charges. However, these small differences are likely of marginal clinical relevance. The study was registered with clinicaltrials.gov at the inception of enrollment (NCT00981136).

Increasing severity of pectus excavatum is associated with reduced pulmonary function.

OBJECTIVE: To determine whether pulmonary function decreases as a function of severity of pectus excavatum, and whether reduced function is restrictive or obstructive in nature in a large multicenter study. STUDY DESIGN: We evaluated preoperative spirometry data in 310 patients and lung volumes in 218 patients aged 6 to 21 years at 11 North American centers. We modeled the impact of the severity of deformity (based on the Haller index) on pulmonary function. RESULTS: The percentages of patients with abnormal forced vital capacity (FVC), forced expiratory volume in 1 second (FEV(1)), forced expiratory flow from 25% exhalation to 75% exhalation, and total lung capacity findings increased with increasing Haller index score. Less than 2% of patients demonstrated an obstructive pattern (FEV(1)/FVC <67%), and 14.5% demonstrated a restrictive pattern (FVC and FEV(1) <80% predicted; FEV(1)/FVC >80%). Patients with a Haller index of 7 are >4 times more likely to have an FVC of ≤80% than those with a Haller index of 4, and are also 4 times more likely to exhibit a restrictive pulmonary pattern. CONCLUSIONS: Among patients presenting for surgical repair of pectus excavatum, those with more severe deformities have a much higher likelihood of decreased pulmonary function with a restrictive pulmonary pattern.

Analysis of the pediatric surgery match: factors predicting outcome.

INTRODUCTION: Applicants in the NRMP for pediatric surgery have little objective data available regarding factors predicting successful matching. We analyzed data from applicants at our institution to attempt to identify parameters correlated with three outcomes: successfully matching, or attaining either a top ten or top three ranking in our final submitted match list. METHODS: After IRB approval, we reviewed ERAS documents for all applicants (n = 146) over 3 years (candidates for the 2007, 2008, and 2009 fellowship years). An interview was offered to 75% of the applicants (Table 1). We analyzed over 20 factors; including demographics, number of publications and first author publications, number of book chapters, national presentations, prior match attempts, advanced degrees, quality of recommendation letters, and ABSITE scores. Significant variables were evaluated with multiple logistic regression analysis to identify independent predictors. RESULTS: Variables correlated with successful outcome for each of the three endpoints are shown in Table 2. The number of peer-reviewed publications and first author publications, and AOA membership were highly correlated with a favorable outcome for all three endpoints. High ABSITE scores were significantly correlated with top ten rank. Research experience and outstanding letters of recommendation were significantly associated with a top ten ranking and overall match success. Variables associated only with overall match success included number of book chapters, graduation from a US medical school, quality of recommendation letters, and being granted an interview at our institution. Logistic regression analysis demonstrated no independent factors for overall match success; number of publications was significant for both top ten and top three ranking (P = 0.006 for each); number of first author publications (P = 0.002) and AOA membership (P = 0.03) were independent predictors for top three ranking. CONCLUSIONS: Applicant variables associated with success in the match included quality of letters, number and type of publications, research experience, graduation from a US medical school, and AOA membership. Factors not correlated with outcome included advanced degrees (PhD, Masters), other fellowship training, and community-based versus university-based residency training. Logistic regression analysis demonstrated no independent factors for overall match success.

Laparoscopic cholecystectomy in the pediatric population.

BACKGROUND: The experience with laparoscopic cholecystectomy in children trails the adult numbers and remains underreported. Therefore, we reviewed our experience with this approach. METHODS: A retrospective review of our most recent 6-year experience with laparoscopic cholecystectomy at Children's Mercy Hospital (Kansas City, MO) between September 5, 2000, and June 1, 2006, was performed. Data points reviewed included patient demographics, indication for operation, operative time, complications, and recovery. RESULTS: During the study period, 224 patients underwent a laparoscopic cholecystectomy. The mean age was 12.9 years (range, 0-21) with a mean weight of 58.3 kg (range, 3-121). Indications for laparoscopic cholecystectomy were symptomatic gallstones in 166 children, biliary dyskinesia in 35, gallstone pancreatitis in 7, gallstones and an indication for splenectomy in 6, calculous cholecystitis in 5, choledocholithiasis in 1, gallbladder polyps in 1, acalculous cholecystitis in 1, and congenital cystic duct obstruction in 1. The mean operative time (excluding patients with concomitant operations) was 77 minutes (range, 30-285). An intraoperative cholangiogram was performed in 38 patients. Common bile duct (CBD) stones were cleared intraoperatively in 5 patients. Two patients required a postoperative endoscopy to retrieve CBD stones. One sickle-cell patient developed a postoperative hemorrhage, requiring a laparotomy. There were no conversions, ductal injuries, bile leaks, or mortality. Biliary dyskinesia was diagnosed in 10% of the first 30 patients in this series and 40% of the most recent 30 patients. The mean ejection fraction in these patients was 21%. All experienced an improvement in their symptoms after the cholecystectomy. CONCLUSIONS: Laparoscopic cholecystectomy is safe and effective in children. Biliary dyskinesia is becoming more frequently diagnosed in children, and these patients respond favorably to cholecystectomy. As opposed to the adult population, the incidence of complicated gallstone disease appears less common in children, as most present with symptomatic cholelithiasis without active inflammation, accounting for the very low rate of ductal complications.

Current application of thoracoscopy in children.

BACKGROUND: The safety and efficacy of thoracoscopy for thoracic lesions and conditions in children is evolving. Our experience with thoracoscopy has expanded in recent years. Therefore, we reviewed our most recent 7-year experience to examine the current applications for thoracoscopy in children. METHODS: A retrospective review of all patients undergoing a thoracoscopic operation at Children's Mercy Hospital (Kansas City, MO) between January 1, 2000, and June 18, 2007, was performed. Data points reviewed included patient demographics, type of operation, final diagnosis, complications, and recovery. RESULTS: During the study period, 230 children underwent 231 thoracoscopic procedures. The mean age was 9.6 +/- 6.1 years with a mean weight of 36.6 +/- 24.1 kg. Fifty percent of the patients were male. The thoracoscopic approach was used for decortication and debridement for empyema in 79 patients, wedge resection for lung lesions in 37, exposure for correction of scoliosis in 26, excision or biopsy of an extrapulmonary mass in 26, operation for spontaneous pneumothorax in 25, lung biopsy for a diffuse parenchymal process in 15, lobectomy in 9, repair of esophageal atresia with a tracheoesophageal fistula (EA-TEF) in 8, clearance of the pleural space for hemothorax or effusion in 3, diagnosis for trauma in 1, and repair of bronchopleural fistula in 1. Conversion was required in 3 patients, all of whom were undergoing a lobectomy. Two of these were right upper lobectomies and the other was a left lower lobectomy with severe infection and inflammation. The mean time of chest tube drainage (excluding scoliosis and EA-TEF patients) was 2.9 +/- 2.0 days. There were no major intraoperative thoracoscopic complications. A correct diagnosis was rendered in all patients undergoing a biopsy. One patient required a second thoracoscopic biopsy to better define a mediastinal mass. Two patients developed postoperative atelectasis after scoliosis procedures. One patient had a small persistent pneumothorax after a bleb resection for a spontaneous pneumothorax. This subsequently resolved. CONCLUSIONS: In pediatric patients with thoracic pathology, thoracoscopy is highly effective for attaining the goal of the operation, with a low rate of conversion and complications.

Prospective multicenter study of surgical correction of pectus excavatum: design, perioperative complications, pain, and baseline pulmonary function facilitated by internet-based data collection.

BACKGROUND: Given widespread adoption of the Nuss procedure, prospective multicenter study of management of pectus excavatum by both the open and Nuss procedures was thought desirable. Although surgical repair has been performed for more than 50 years, there are no prospective multicenter studies of its management. STUDY DESIGN: This observational study followed pectus excavatum patients treated surgically at 11 centers in North America, according to the method of choice of the patient and surgeon. Before operation, all underwent evaluation with CT scan, pulmonary function tests, and body image survey. Data were collected about associated conditions, hospital complications, and perioperative pain. One year after completion of treatment, patients will repeat the preoperative evaluations. This article addresses early results only. RESULTS: Of 416 patients screened, 327 were enrolled; 284 underwent the Nuss procedure and 43 had the open procedure. Median preoperative CT index was 4.4. Pulmonary function testing before operation showed mean forced vital capacity of 90% of predicted values; forced expiratory volume in 1 second (FEV(1)), 89% of predicted; and forced expiratory flow during the middle half of the forced vital capacity (FEF(25% to 75%)), 85% of predicted. Early postcorrection results showed that operations were performed without mortality and with minimal morbidity at 30 days postoperatively. Median hospital stay was 4 days. Postoperative pain was a median of 3 on a scale of 10 at time of discharge; the worst pain experienced was the same as was expected by the patients (median 8), and by 30 days after correction or operation, the median pain score was 1. Because of disproportionate enrollment and similar early complication rates, statistical comparison between operation types was limited. CONCLUSIONS: Anatomically severe pectus excavatum is associated with abnormal pulmonary function. Initial operative correction performed at a variety of centers can be completed safely. Perioperative pain is successfully managed by current techniques.

A financial analysis of pediatric laparoscopic versus open fundoplication.

INTRODUCTION: Laparoscopic fundoplication (LF) is rapidly replacing open fundoplication (OF) for correcting symptomatic gastroesophageal reflux (GER) in infants and children. In this study, we compared various clinical and financial parameters to determine if one technique is superior. METHODS: With Institutional Review Board approval, charts and charge data for 50 consecutive patients undergoing elective LF or OF were reviewed in 2003 and 2004 (n = 100). Clinical variables evaluated included gender, age, weight, length of stay (LOS), operating time (OT), and time to initial (IF) and full (FF) feedings. Financial charges that were reviewed included anesthesia, central supply and sterilization, equipment, operating suite, hospital room and board, pharmacy, and total charges. RESULTS: The groups were equally matched in relation to gender, age, and weight. The table below illustrates the statistically significant differences (P < 0.05) between the groups. Favoring LNF LOS (1.2 vs. 2.9 days) IF (7.3 vs. 27.9 hours) FF (21.8 vs. 42.9 hours) Equipment ($1,006 vs. $1,609) Hospital Room ($1,290 vs. $2,847) Pharmacy ($180 vs. $461), Favoring OF OT (77 vs. 91 minutes) Anesthesia ($389 vs. $475) Central Supply and Sterilization ($1,367 vs. $2,515) Operating Suite ($4,058 vs. $5,142) Total charges were similar (LF, $11,449; OF, $11,632). CONCLUSIONS: Interestingly, although there were statistical differences in every charge category, total charges for LF and OF did not differ significantly. Thus, traditionally higher expenses from longer OT for LF seem to be offset by financial benefits, such as shorter LOS, reduced discomfort as evidenced by lower narcotic charges, and earlier IF/FF.

The Minimally Invasive Repair of Pectus Excavatum Using a Subxiphoid Incision.

Purpose Several surgeons have documented outcomes following the Nuss operation. Most reports have described the use of thoracoscopy to avoid cardiac injury. Since 1999, our group has utilized a subxiphoid incision, allowing insertion of the surgeon's finger into the substernal space to help guide the bar across the mediastinum. Our initial experience has been reported and we are now reporting our entire experience to date. Methods A retrospective review was conducted on all patients who underwent pectus excavatum repair using a subxiphoid incision from December, 1999 to September, 2015. Results During the study period, 554 repairs were performed. A total of 80% of the patients were male. The mean age was 14.3 years ± 3.1, the mean operating time was 52 minutes ± 17.4, the mean length of stay was 4.2 days ± 1.1, and the mean time to bar removal was 2.7 years ± 0.7. A total of 20 patients (3.6%) received two bars. No patients sustained cardiac injury or evidence of pericarditis. Postoperatively, 22 patients (4%) developed an infection, either cellulitis or a local abscess requiring incision and drainage and/or antibiotics. In four of these 22 patients, the wound infection developed after the bar had been removed. Only one patient required bar removal before 2 years due to an infection. A total of 12 patients required either repositioning of the bar due to rotation (4) or removal of a stabilizer due to chronic discomfort (8), 2 required early bar removal for chronic pain, and 1 patient developed a tension pneumothorax in the operating room. A recurrence has developed in two patients but neither patient has desired correction. Conclusion In this relatively large series of patients, the addition of a subxiphoid incision to the technique has allowed for safe passage of the bar across the mediastinum to avoid cardiac injury during the Nuss operation.

Biobrane versus duoderm for the treatment of intermediate thickness burns in children: a prospective, randomized trial.

In this study, we directly compared the efficacy of Biobrane and Duoderm for the treatment of small intermediate thickness burns in children in a prospective, randomized fashion to determine their relative impact on wound healing, pain scores, and cost. Patients under 18 years of age with intermediate thickness burns on a surface area less than 10% were enrolled and treated with one of the two dressing systems. Data collected included mechanism of injury, time to complete healing, pain scores, and institutional cost of materials until healing was complete. No significant difference in time to healing or pain scores was detected between the two groups. The cost of each treatment was statistically more expensive in the Biobrane group. The results of this study demonstrate that Duoderm and Biobrane provide equally effective treatment of partial thickness burns among in the pediatric population. However, Duoderm is statistically less expensive than Biobrane and can be considered a first-line treatment option for intermediate thickness burn wounds in children.

An effective pyloromyotomy length in infants undergoing laparoscopic pyloromyotomy.

BACKGROUND: Traditional management of pyloric stenosis has consisted of open pyloromyotomy during which the surgeon is able to palpate and determine whether the hypertrophied pylorus has been completely divided. During the last decade, laparoscopic pyloromyotomy has become an increasingly popular approach for this condition. The purpose of this study was to determine whether there is an effective pyloromyotomy length that will allow the surgeon to feel confident that a complete pyloromyotomy was performed with the laparoscopic approach. METHODS: All infants undergoing laparoscopic pyloromyotomy from October 1999 through October 2003 at a single institution were retrospectively studied. Clinical variables collected included the patient's age, gender, electrolyte status on admission, the elapsed time from admission to operation, ultrasonographic dimensions of the hypertrophied pylorus, operative time, the length of the pyloromyotomy performed, the time to initial and to full feedings, and the duration of the postoperative hospitalization. RESULTS: One hundred seventy-one patients comprised the study group. The age (mean +/- standard deviation) at the time of operation was 5.2 +/- 2.8 weeks. The mean preoperative ultrasonic measurements for both pyloric thickness and pyloric length were 4.3 +/- 0.7 mm and 19.5 +/- 2.8 mm, respectively. The average pyloromyotomy incision length for this entire group was 1.9 +/- 0.21 cm. The mean operative time was 23.5 +/- 8.3 minutes. There were no mucosal perforations, no conversions to an open procedure, and no evidence for an incomplete pyloromyotomy. CONCLUSIONS: Laparoscopic pyloromyotomy is a safe and effective technique for infants with pyloric stenosis. A pyloromyotomy incision length of approximately 2 cm appears to be an effective measure of a complete pyloromyotomy.

Single incision versus standard 4-port laparoscopic cholecystectomy: a prospective randomized trial.

BACKGROUND: Laparoscopy through a single umbilical incision is an emerging technique supported by case series, but prospective comparative data are lacking. Therefore, we conducted a prospective, randomized trial comparing single site umbilical laparoscopic cholecystectomy to 4-port laparoscopic cholecystectomy. METHODS: After IRB approval, patients were randomized to laparoscopic cholecystectomy via a single umbilical incision or standard 4-port access. The primary outcome variable was operative time. Utilizing a power of 0.8 and an alpha of 0.05, 30 patients were calculated for each arm. Patients with complicated disease or weight over 100 kg were excluded. Post-operative management was controlled. Surgeons subjectively scored degree of technical difficulty from 1=easy to 5=difficult. RESULTS: From 8/2009 through 7/2011, 60 patients were enrolled. There were no differences in patient characteristics. Operative time and degree of difficulty were greater with the single site approach. There were more doses of analgesics used and greater hospital charges in the single site group that trended toward significance. CONCLUSION: Single site laparoscopic cholecystectomy produces longer operative times with a greater degree of difficulty as assessed by the surgeon. There was a trend toward more doses of post-operative analgesics and greater hospital charges with the single site approach.

Multicenter study of pectus excavatum, final report: complications, static/exercise pulmonary function, and anatomic outcomes.

BACKGROUND: A multicenter study of pectus excavatum was described previously. This report presents our final results. STUDY DESIGN: Patients treated surgically at 11 centers were followed prospectively. Each underwent a preoperative evaluation with CT scan, pulmonary function tests, and body image survey. Data were collected about associated conditions, complications, and perioperative pain. One year after treatment, patients underwent repeat chest CT scan, pulmonary function tests, and body image survey. A subset of 50 underwent exercise pulmonary function testing. RESULTS: Of 327 patients, 284 underwent Nuss procedure and 43 underwent open procedure without mortality. Of 182 patients with complete follow-up (56%), 18% had late complications, similarly distributed, including substernal bar displacement in 7% and wound infection in 2%. Mean initial CT scan index of 4.4 improved to 3.0 post operation (severe >3.2, normal = 2.5). Computed tomography index improved at the deepest point (xiphoid) and also upper and middle sternum. Pulmonary function tests improved (forced vital capacity from 88% to 93%, forced expiratory volume in 1 second from 87% to 90%, and total lung capacity from 94% to 100% of predicted (p < 0.001 for each). VO2 max during peak exercise increased by 10.1% (p = 0.015) and O2 pulse by 19% (p = 0.007) in 20 subjects who completed both pre- and postoperative exercise tests. CONCLUSIONS: There is significant improvement in lung function at rest and in VO2 max and O2 pulse after surgical correction of pectus excavatum, with CT index >3.2. Operative correction significantly reduces CT index and markedly improves the shape of the entire chest, and can be performed safely in a variety of centers.

Treatment of chest wall osteosarcoma presenting as second primary after treatment of neuroblastoma.

Only 2 cases of osteosarcoma as a second primary malignancy after neuroblastoma have been reported in the literature. We present a case of chest wall osteosarcoma that developed in a 14-year-old boy 7 years after completion of chemotherapy, autologous peripheral blood stem cell transplantation, radiation, and resection for stage 3, high-risk neuroblastoma. A biopsy of a painful chest wall mass arising from the right third rib diagnosed osteosarcoma. He went on to have preoperative chemotherapy followed by wide local excision and chest wall reconstruction. He then received additional chemotherapy. This case highlights the importance of close observation for second malignancies in this patient population.

Epidural vs patient-controlled analgesia for postoperative pain after pectus excavatum repair: a prospective, randomized trial.

PURPOSE: Management of postoperative pain is a challenge after the minimally invasive repair of pectus excavatum. Pain is usually managed by either a thoracic epidural or patient-controlled analgesia with intravenous narcotics. We conducted a prospective, randomized trial to evaluate the relative merits of these 2 pain management strategies. METHODS: After obtaining permission/assent (Institutional Review Board no. 06 08 128), patients were randomized to either epidural or patient-controlled analgesia with fixed protocols for each arm. The primary outcome variable was length of stay with a power of .8 and α of .05. RESULTS: One hundred ten patients were enrolled. There was no difference in length of stay between the 2 arms. A longer operative time, more calls to anesthesia, and greater hospital charges were found in the epidural group. Pain scores favored epidural for the few days and favored patient-controlled analgesia thereafter. The epidural catheter could not be placed or was removed within 24 hours in 12 patients (22%). CONCLUSIONS: There is longer operating room time, increase in calls to anesthesia, and greater hospital charges with epidural analgesia after repair of pectus excavatum. Pain scores favor the epidural approach early in the postoperative course and patient-controlled analgesia later.

Topical silver sulfadiazine vs collagenase ointment for the treatment of partial thickness burns in children: a prospective randomized trial.

BACKGROUND: The 2 most commonly used topical agents for partial thickness burns are silver sulfadiazine (SSD) and collagenase ointment (CO). Silver sulfadiazine holds antibacterial properties, and eschar separation occurs naturally. Collagenase ointment is an enzyme that cleaves denatured collagen facilitating separation but has no antibacterial properties. Currently, there are no prospective comparative data in children for these 2 agents. Therefore, we conducted a prospective randomized trial. METHODS: After institutional review board approval, patients were randomized to daily debridement with SSD or CO. Primary outcome was the need for skin grafting. Patients were treated for 2 days with SSD with subsequent randomization. Polymyxin was mixed with CO for antibacterial coverage. Debridements were performed daily for 10 days or until the burn healed. Grafting was performed after 10 days if not healed. RESULTS: From January 2008 to January 2011, 100 patients were enrolled, with no differences in patient characteristics. There were no differences in clinical course, outcome, or need for skin grafting. Wound infections occurred in 7 patients treated with CO and 1 patient treated with SSD (P = .06). Collagenase ointment was more expensive than SSD (P < .001). However, total hospital charges did not differ. CONCLUSION: There are no differences in outcomes between topical SSD or CO in the management of childhood burns results.

Experience with a simple technique for pectus bar removal.

BACKGROUND: There have been numerous reports of techniques used for pectus bar removal after correction of pectus excavatum. We use 2 operating tables positioned perpendicular to each other in a T-shaped configuration with the patients thorax circumferentially exposed so the bar is removed in 1 motion without bending the bar. In this study, we report the results of this procedure. METHODS: A retrospective chart review of patients undergoing bar removal after repair of pectus excavatum at our institution from August 2000 to March 2010 was performed. RESULTS: There were 230 patients with a mean age of 16.7 years (range, 7.8-25.3 years) at bar removal. Mean operative time for bar removal was 28.6 minutes, and average estimated blood loss (EBL) was 9.5 mL (range, 5-400 mL). One patient demonstrated significant hemorrhage from the bar tract after bar removal, which was controlled with circumferential compression wrap. Calcification was noted in 11 patients, and chondroma, in 8 patients. Wound infection after bar removal occurred in 3% of patients. No patient required the bar to be bent into a straight configuration for removal. CONCLUSIONS: Removal of pectus bars using this 2-table T-configuration technique is safe, is time efficient, and obviates the need for bending the bar.

A novel measure for pectus excavatum: the correction index.

OBJECTIVE: The Haller Index (HI), the standard metric for the severity of pectus excavatum, is dependent on width and does not assess the depth of the defect. Therefore, we performed a diagnostic analysis to assess the ability of HI to separate patients with pectus excavatum from healthy controls compared to a novel index. METHODS: After institutional review board approval, computed tomography scans were evaluated from patients who have undergone pectus excavatum repair and controls. The correction index (CI) used the minimum distance between posterior sternum and anterior spine and the maximum distance between anterior spine most anterior portion of the chest. The difference between the two is divided by the latter (×100) to give the percentage of chest depth the defect represents. RESULTS: There were 220 controls and 252 patients with pectus. Mean HI was 2.35, and the mean CI was 0.92 for the controls. The mean HI was 4.06, and the mean CI was 31.75 in the patients with pectus. In the patients with pectus, HI demonstrated a 47.8% overlap with the controls, while there was no overlap for CI. CONCLUSIONS: The Haller index demonstrates 48% overlap between normal patients and those with pectus excavatum. However, the proposed correction index perfectly separates the normal and diseased populations.

Outcomes in children with hypoplastic left heart syndrome undergoing open fundoplication.

BACKGROUND/PURPOSE: Some institutions recommend early fundoplication in patients with hypoplastic left heart syndrome (HLHS) with signs of gastroesophageal reflux disease because of the risk of reflux-related cardiac events. However, their cardiac physiology may impose high perioperative morbidity and mortality. Therefore, we reviewed our experience with fundoplication in this population to allow for assessment of the risk-benefit ratio. METHODS: A retrospective review of patients with a diagnosis of HLHS who underwent a fundoplication from January 1990 to July 7, 2009, was performed. All patients underwent open fundoplication between first and second stages of cardiac repair. RESULTS: Thirty-nine patients were identified. There were 3 intraoperative complications: hemodynamic instability (n = 2) and a pulmonary hypertensive crisis requiring extracorporeal membrane oxygenation and termination of the procedure (n = 1). There were 27 postoperative complications in 16 patients. There were 2 deaths (4%) within 30 days, and there were 9 deaths (23%) in patients between their first and second stage of cardiac repair during the study period. CONCLUSIONS: Noncardiac surgical procedures in patients palliated for HLHS have a high morbidity and mortality. We recommend that routine fundoplication in this population should only be performed under prospective protocols until the relative risk of operation vs risk of reflux is delineated.
