Duodenal Atresia Repair: A Single-Center Comparative Study.

BACKGROUND: The use of laparoscopy in the repair of duodenal atresia has been increasing. However, there is no consensus regarding which surgical approach has better outcomes. We aimed to compare the different surgical approaches and types of anastomoses for duodenal atresia repair. METHODS: Patients who underwent duodenal atresia repair at a single pediatric center were identified between January 2006 and June 2022. Those with concomitant gastrointestinal anomalies or who required other simultaneous operations were excluded. The primary outcome was rate of complications, defined as rate of leak, stricture, and re-operation by surgical approach and technique of anastomosis. RESULTS: A total of 78 patients were included. The majority were female (51.3%, n = 40), with a median age of 4 days (IQR 3.0,8.0) and a median weight of 2.7 kg (IQR 2.2,3.3) at repair. The re-operation rate was 7.7% (n = 6), of which two were anastomotic leaks, and four were anastomotic strictures. The leak rate was 5.6% (n = 1/18) for the open handsewn and 4.8% (n = 1/21) for the laparoscopic handsewn technique. The stricture rate was 12.5% (n = 1/8) for the laparoscopic-assisted handsewn, 9.1% (n = 2/22) for the laparoscopic U-clip, 4.8% (n = 1/21) for the laparoscopic handsewn, and none with laparoscopic stapled and laparoscopic converted to open handsewn techniques. No differences were found in complication rate when controlling for surgical approach. CONCLUSION: The method of surgical approach did not affect the outcomes or complications in the repair of duodenal atresia.

Hypertrophic Pyloric Stenosis Protocol: A Single Center Study.

BACKGROUND: Initial treatment of hypertrophic pyloric stenosis (HPS) is correction of electrolyte disturbances with fluid resuscitation. In 2015, our institution implemented a fluid resuscitation protocol based on previous data that focused on minimizing blood draws and allowing immediate ad libitum feeds postoperatively. Our aim was to describe the protocol and subsequent outcomes. METHODS: We conducted a single-center retrospective review of patients diagnosed with HPS from 2016 to 2023. All patients were given ad libitum feeds postoperatively and discharged home after tolerating three consecutive feeds. The primary outcome was the postoperative hospital length of stay (LOS). Secondary outcomes included the number of preoperative labs drawn, time from arrival to surgery, time from surgery to initiation of feeds, time from surgery to full feeds, and re-admission rate. RESULTS: The study included 333 patients. A total of 142 patients (42.6%) had electrolytic disturbances that required fluid boluses in addition to 1.5x maintenance fluids. The median number of lab draws was 1 (IQR 1,2), with a median time from arrival to surgery of 19.5 hours (IQR 15.3,24.9). The median time from surgery to first and full feed was 1.9 hours (IQR 1.2,2.7) and 11.2 hours (IQR 6.4,18.3), respectively. Patients had a median postoperative LOS of 21.8 hours (IQR 9.7,28.9). Re-admission rate within the first 30 postoperative days was 3.6% (n = 12) with 2.7% of re-admissions occurring within 72 hours of discharge. One patient required re-operation due to an incomplete pyloromyotomy. DISCUSSION: This protocol is a valuable tool for perioperative and postoperative management of patients with HPS while minimizing uncomfortable intervention.

Management of Primary Spontaneous Pneumothorax in Children: A Single Institution Protocol Analysis.

BACKGROUND: The Midwest Pediatric Surgery Consortium (MWPSC) suggested a simple aspiration of primary spontaneous pneumothorax (PSP) protocol, failing which, Video-Assisted Thoracoscopic Surgery (VATS) should be considered. We describe our outcomes using this suggested protocol. METHODS: A single institution retrospective analysis was conducted on patients between 12 and 18 years who were diagnosed with PSP from 2016 to 2021. Initial management involved aspiration alone with a ≤12 F percutaneous thoracostomy tube followed by clamping of the tube and chest radiograph at 6 h. Success was defined as ≤2 cm distance between chest wall and lung at the apex and no air leak when the clamp was released. VATS followed if aspiration failed. RESULTS: Fifty-nine patients were included. Median age was 16.8 years (IQR 15.9, 17.3). Aspiration was successful in 33% (20), while 66% (39) required VATS. The median LOS with successful aspiration was 20.4 h (IQR 16.8, 34.8), while median LOS after VATS was 3.1 days (IQR 2.6, 4). In comparison, in the MWPSC study, the mean LOS for those managed with a chest tube after failed aspiration was 6.0 days (±5.5). Recurrence after successful aspiration was 45% (n = 9), while recurrence after VATS was 25% (n = 10). Median time to recurrence after successful aspiration was sooner than that of the VATS group [16.6 days (IQR 5.4, 19.2) vs. 389.5 days (IQR 94.1, 907.0) p = 0.01]. CONCLUSION: Simple aspiration is safe and effective initial management for children with PSP, although most will require VATS. However, early VATS reduces length of stay and morbidity. LEVEL OF EVIDENCE: IV. Retrospective study.

Institutional outcomes of blunt liver and splenic injury in the Arizona-Texas-Oklahoma-Memphis-Arkansas Consortium era.

BACKGROUND: The Arizona-Texas-Oklahoma-Memphis-Arkansas Consortium practice management guideline was created to standardize management of blunt liver or spleen injury across pediatric trauma centers. We describe our outcomes since guideline adoption at our institution and hypothesize that blunt liver or spleen injury may be managed more expeditiously than currently reported without compromising safety. METHODS: A retrospective cohort study was conducted on patients younger than 18 years presenting with blunt liver and/or splenic injuries from March 2016 to March 2021 at one participating center. RESULTS: A total of 199 patients were included. There were no clinically relevant differences for age, body mass index, or sex among the cohort. Isolated splenic injuries (n = 91 [46%]) and motor vehicle collisions (n = 82 [41%]) were the most common injury and mechanism, respectively. The overall median length of stay (LOS) was 1.2 days (interquartile range, 0.45-3.3 days). Intensive care unit utilization was 23% (n = 46). There was no statistically significant difference in median LOS among patients with isolated solid organ injuries, regardless of injury grade. There were no readmissions associated with non-operative management. CONCLUSION: The Arizona-Texas-Oklahoma-Memphis-Arkansas Consortium guideline fosters high rates of nonoperative management with low intensive care unit utilization and LOS while demonstrating safety in implementation, irrespective of injury grade. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level IV.

Laparoscopic Gastrostomy in Infants During an Open Abdominal Procedure: A Novel Approach.

Introduction: Infants with intra-abdominal pathology necessitating open abdominal surgery may also require placement of a gastrostomy tube (GT). Use of laparoscopy provides better visualization for gastrostomy placement and lowers the risk of complications compared with an open approach. We describe a series of patients who underwent laparoscopic GT placement at the time of an open abdominal procedure. Methods: All patients who underwent an open abdominal procedure with concurrent laparoscopic gastrostomy from January 2010 to June 2020 were reviewed. Descriptive statistics were performed with categorical variables reported as proportions and continuous variables reported as medians with interquartile range [IQR]. Results: Twelve patients were included; 8 (67.5%) were male. The median age at time of surgery was 10 weeks [IQR 6, 14], with a median weight of 4.1 kg [IQR 3.4, 4.8]. Ten patients had the laparoscope placed through the open incision, whereas 2 had the laparoscope placed through a separate incision. Median operative time was 106 minutes [IQR 80, 125]. There were no intraoperative complications. Postoperative complications included surgical site infection in 5 (41.7%), leaking around the GT in 3 (25%), and malfunction of the tube in 1 (8.3%). One patient required reoperation 28 days postoperatively due to malfunction. Conclusion: Laparoscopic GT can be safely performed at the time of an open abdominal procedure, and frequently through the same incision, harnessing the benefits of a laparoscopic approach even when an open incision is needed.

Short and long term outcomes of using cryoablation for postoperative pain control in patients after pectus excavatum repair.

INTRODUCTION: We report the findings of a three-year prospective observational study elucidating long-term symptoms and complications of patients who underwent minimally invasive pectus excavatum repair with intercostal nerve cryoablation with specific attention to postoperative pain control associated with the cryoablation technique. METHODS: Surveys were administered to patients who underwent bar placement for pectus excavatum with intercostal nerve cryoablation from 2017 to 2021 regarding pain scores, pain medication usage, and limitations to activity beginning on the day of surgery, on the day of discharge, and at two-week and three-month follow-up. RESULTS: Of 110 patients, forty-eight (44%) completed the discharge survey; sharp pain and pressure on the first postoperative night were the most described pain characteristics, most frequently in the middle of the chest. On follow-up, 55% of patients reported tolerable residual pain at two weeks and 41% at three months, with 25% requiring intermittent pain medication at three months. There were three readmissions for inadequate pain control and 110 calls to the surgery clinic by three-month follow-up, most commonly for persistent pain and frequent popping sensation with movement. DISCUSSION: Although cryoablation is an excellent pain control modality, these data suggest that patients underreport functional symptoms and experience more frequent discomfort and alteration of daily living activities.

Outpatient Botulinum Injections for Early Obstructive Symptoms in Patients with Hirschsprung Disease.

INTRODUCTION: Botulinum toxin (BT) injections may play a role in preventing Hirschsprung associated enterocolitis (HAEC) episodes related to internal anal sphincter (IAS dysfunction). Our aim was to determine the association of outpatient BT injections for early obstructive symptoms on the development of HAEC. METHODS: A retrospective review of children who underwent definitive surgery for Hirschsprung disease (HSCR) from July 2010 - July 2020 was performed. The timing from pull-through to first HAEC episode and to first BT injection was recorded. Primary analysis focused on the rate of HAEC episodes and timing between episodes in patients who did and did not receive BT injections. RESULTS: Eighty patients were included. Sixty patients (75%) were male, 15 (19%) were diagnosed with trisomy 21, and 58 (72.5%) had short-segment disease. The median time to pull-through was 150 days (IQR 16, 132). Eight patients (10%) had neither an episode of HAEC or BT injections and were not included in further analysis. Forty-six patients (64%) experienced at least one episode of HAEC, while 64 patients (89%) had at least one outpatient BT injection. Compared to patients who never received BT injections (n = 9) and those who developed HAEC prior to BT injections (n = 35), significantly fewer patients who received BT injections first (n = 28) developed enterocolitis (P < 0.001), with no patient developing more than one HAEC episode. CONCLUSION: Outpatient BT is associated with decreased episodes of HAEC and increased interval between HAEC episodes requiring inpatient treatment. Scheduling outpatient BT injections to manage obstructive symptoms may be beneficial after pull-through for HSCR.

Behind the mask: extended use of surgical masks is not associated with increased risk of surgical site infection.

PURPOSE: COVID-19 has prompted significant policy change, with critical attention to the conservation of personal protective equipment (PPE). An extended surgical mask use policy was implemented at our institution, allowing use of one disposable mask per each individual, per day, for all the cases. We investigate the clinical impact of this policy change and its effect on the rate of 30-day surgical site infection (SSI). METHODS: A single-institution retrospective review was performed for all the elective pediatric general surgery cases performed pre-COVID from August 2019 to October 2019 and under the extended mask use policy from August 2020 to October 2020. Procedure type, SSI within 30 days, and postoperative interventions were recorded. RESULTS: Four hundred and eighty-eight cases were reviewed: 240 in the pre-COVID-19 cohort and 248 in the extended surgical mask use cohort. Three SSIs were identified in the 2019 cohort, and two in the 2020 cohort. All postoperative infections were superficial and resolved within 1 month of diagnosis with oral antibiotics. There were no deep space infections, readmissions, or infections requiring re-operation. CONCLUSION: Extended surgical mask use was not associated with increased SSI in this series of pediatric general surgery cases and may be considered an effective and safe strategy for resource conservation with minimal clinical impact.

Evaluation of a fluid resuscitation protocol for patients with hypertrophic pyloric stenosis.

INTRODUCTION: We previously developed an institutional, evidence-based fluid resuscitation protocol for neonates with infantile hypertrophic pyloric stenosis (HPS) based on the severity of electrolyte derangement on presentation. We aim to evaluate this protocol to determine its efficacy in reducing the number of preoperative lab draws, time to electrolyte correction, and overall length of stay. METHODS: A single center, retrospective review of 319 infants with HPS presenting with electrolyte derangement from 2008 to 2020 was performed; 202 patients managed pre-protocol (2008-2014) and 117 patients managed per our institutional fluid resuscitation algorithm (2016-2020). The number of preoperative lab draws, time to electrolyte correction, and length of stay before and after protocol implementation was recorded. RESULTS: Use of a fluid resuscitation algorithm decreased the number of infants who required four or more preoperative lab draws (20% vs. 6%) (p < .01), decreased median time to electrolyte correction between the pre and post protocol cohorts (15.1 h [10.6, 22.3] vs. 11.9 h [8.5, 17.9]) (p < .01), and decreased total length of hospital stay (49.0 h [40.3, 70.7] vs. 45.7 h [34.3, 65.9]) (p < .05). CONCLUSION: Implementation of a fluid resuscitation algorithm for patients presenting with hypertrophic pyloric stenosis decreases the frequency of preoperative lab draws, time to electrolyte correction, and total length of hospital stay. Use of a fluid resuscitation protocol may decrease discomfort through fewer preoperative lab draws and shorter length of stay while setting clear expectations and planned intervention for parents. LEVEL OF EVIDENCE: III - Retrospective comparative study.

Review of Perioperative Prophylactic Antibiotic Use during Laparoscopic Cholecystectomy and Subsequent Surgical Site Infection Development at a Single Children's Hospital.

OBJECTIVES: With the rise of antibiotic resistance, the use of prophylactic preoperative antibiotics (PPA) has been questioned in cases with low rates of surgical site infection (SSI). We report PPA usage and SSI rates after elective laparoscopic cholecystectomy at our institution. MATERIALS AND METHODS: A retrospective review of children younger than 18 years who underwent elective outpatient laparoscopic cholecystectomy between July 2010 and August 2020 was performed. Demographic, preoperative work-up, antibiotic use, intraoperative characteristics, and SSI data were collected via chart review. SSI was defined as clinical signs of infection that required antibiotics within 30 days of surgery. RESULTS: A total of 502 patients met the inclusion criteria; 50% were preoperatively diagnosed with symptomatic cholelithiasis, 47% with biliary dyskinesia, 2% with hyperkinetic gallbladder, and 1% with gallbladder polyp(s). The majority were female (78%) and Caucasian (80%). In total, 60% (n = 301) of patients received PPA, while 40% (n = 201) did not; 1.3% (n = 4) of those who received PPA developed SSI, compared with 5.5% (n = 11) of those who did not receive PPA (p = 0.01). Though PPA use was associated with a 77% reduction in the risk of SSI in multivariate analysis (p = 0.01), all SSIs were superficial. One child required readmission for intravenous antibiotics, while the remainder were treated with outpatient antibiotics. Gender, age, body mass index, ethnicity, and preoperative diagnosis did not influence the likelihood of receiving PPA. CONCLUSION: Given the relatively low morbidity of the superficial SSI, conservative use of PPA is advised to avoid contributing to antibiotic resistance.

Umbilical access in laparoscopic surgery in infants less than 3 months: A single institution retrospective review.

INTRODUCTION: Umbilical access in laparoscopic surgery has been cited as a factor for increased complications in low-birth-weight infants and those less than three months old. In a previous series, 10.6% of pediatric surgeons reported complications in this population associated with umbilical access, citing carbon dioxide (CO2) embolism as the most common complication. To further examine the safety of this technique, we report our outcomes with blunt transumbilical laparoscopic access at our institution over four years. METHODS: A retrospective review was performed of patients less than three months of age who underwent laparoscopic pyloromyotomy or inguinal hernia repair from 2016 to 2019. Operative reports, anesthesia records, and postoperative documentation were reviewed for complications related to umbilical access. Complications included bowel injury, vascular injury, umbilical vein cannulation, CO2 embolism, umbilical surgical site infection (SSI), umbilical hernia requiring repair, and death. RESULTS: Of 365 patients, 246 underwent laparoscopic pyloromyotomy, and 119 underwent laparoscopic inguinal hernia repairs. Median age at operation was 5.9 weeks [4.3,8.8], and median weight was 3.9 kg [3.4,4.6]. Nine complications (2.5%) occurred: 5 umbilical SSIs (1.4%), 1 bowel injury upon entry requiring laparoscopic repair (0.2%), 1 incisional hernia repair 22 days postoperatively (0.2%), and 2 cases of hypotension and bradycardia upon insufflation that resolved with desufflation (0.5%). There were no intraoperative mortalities or signs/symptoms of CO2 embolism. CONCLUSION: In this series, umbilical access for laparoscopic surgery in neonates less than three months of age was safe, with minimal complications. Although concern for umbilical vessel injury, cannulation, and CO2 embolism exists, these complications are not exclusively associated with umbilical access technique.

A single institution experience with Laparoscopic Hernia repair in 791 children.

INTRODUCTION: There are many described technique to performing laparoscopic inguinal hernia repair in children. We describe our outcomes using a percutaneous internal ring suturing technique. METHODS: A retrospective review of patients under 18 years old who underwent repair between January 2014 - March 2019 was performed. A percutaneous internal ring suturing technique, involving hydro-dissection of the peritoneum, percutaneous suture passage, and cauterization of the peritoneum in the sac prior to high ligation, was used. p < 0.05 was considered significant during the analysis. RESULTS: 791 patients were included. The median age at operation was 1.9 years (IQR 0.37, 5.82). The median operative time for a unilateral repair was 21 min (IQR 16, 28), while the median time for a bilateral repair was 30.5 min (IQR 23, 41). In total, 3 patients required conversion to an open procedure (0.4%), 4 (0.6%) experienced post-operative bleeding, 9 (1.2%) developed a wound infection, and iatrogenic ascent of testis occurred in 10 (1.3%) patients. Twenty patients (2.5%) developed a recurrent hernia. All but two were re-repaired laparoscopically. CONCLUSIONS: The use of percutaneous internal ring suturing for laparoscopic repair of inguinal hernias in the pediatric population is safe and effective with a low rate of complications and recurrence.

Same-day discharge for pediatric laparoscopic gastrostomy.

BACKGROUND: Laparoscopic gastrostomy is a common procedure in children. We developed a same-day discharge (SDD) protocol for laparoscopic button gastrostomy. METHODS: We performed a prospective observational study of children undergoing laparoscopic button gastrostomy and were eligible for SDD from August 2017-September 2019. Patients were eligible if: 1) the family was comfortable with eliminating overnight admission and were suitable candidates for outpatient surgery (absence of major co-morbidities), 2) they were not undergoing additional procedures requiring admission, and 3) they received pre-operative education. RESULTS: Sixty-two patients who underwent laparoscopic button gastrostomy were eligible for SDD. The median age was 2.1 years [IQR 0.9-4.1], and the median weight was 10.5 kg [IQR 7.6-15.5]. Forty-one (66%) were previously nasogastric fed. The median operative time was 22 min [IQR 16-29]. The median time to initiation of feeds was 4.4 h [IQR 3.4-5.5]. Fifty-one (82%) were discharged the same day with a median length of stay of 9 h [IQR 7-10]. Eleven were admitted, most commonly for further teaching. Eleven SDD patients were seen in the emergency room <30 days at a median 5 days [IQR 3-12] post-operatively, primarily for mechanical complications. CONCLUSION: Same-day discharge following laparoscopic gastrostomy is safe and feasible for select pediatric patients who undergo pre-operative education. The SDD pathway results in a low admission rate and relatively low ER visits. TYPE OF STUDY: Prospective Observational Study. LEVEL OF EVIDENCE: Level II.

Inpatient management of Hirschsprung's associated enterocolitis treatment: the benefits of standardized care.

INTRODUCTION: Patients with Hirschsprung's disease (HSCR) remain at risk of developing Hirschsprung-associated enterocolitis (HAEC) after surgical intervention. As inpatient management remains variable, our institution implemented an algorithm directed at standardizing treatment practices. This study aimed to compare the outcomes of patients pre- and post-algorithm. METHODS: A retrospective review of patients admitted for HAEC was performed; January 2017-June 2018 encompassed the pre-implementation period, and October 2018-October 2019 was the post-implementation period. Demographics and outcomes were compared between the two groups. RESULTS: Sixty-two episodes of HAEC occurred in 27 patients during the entire study period. Sixteen patients (59%) had more than one episode. The most common levels of the transition zone were the rectosigmoid (50%) and descending colon (27%). Following algorithm implementation, the median length of stay (2 vs. 7 days, p < 0.001), TPN duration (0 vs. 5.5 days, p < 0.001), and days to full enteral diet (6 days vs. 2 days, p < 0.001) decreased significantly. Readmission rates for recurrent enterocolitis were similar pre- and post-algorithm implementation. CONCLUSION: The use of a standardized algorithm significantly decreases the length of stay and duration of intravenous antibiotic administration without increasing readmission rates, while still providing appropriate treatment for HAEC. LEVEL OF EVIDENCE: III level. TYPE OF STUDY: Retrospective comparative study.

Ligament of Treitz Release With Duodenal Lowering for Pediatric Superior Mesenteric Artery Syndrome.

BACKGROUND: Operative approaches for superior mesenteric artery syndrome (SMAS) vary from Roux-en-Y duodenojejunostomy to the more conservative division of the ligament of Treitz with inferior duodenal derotation known as the Strong procedure. We sought to examine outcomes following a modified version of Strong procedure where the duodenum is lowered as opposed to derotated for the management of SMAS. MATERIALS AND METHODS: We conducted a retrospective chart review of children who underwent surgical management of SMAS between January 2008 and December 2017. An online survey regarding symptom resolution, feeding practices, and the need for additional procedures was distributed. Data are reported as medians with interquartile range (IQR) and proportions as percentages. RESULTS: Seven patients with a median age of 15 y (IQR 8, 16) and median body mass index of 16.9 (IQR, 12.6, 22.1) were included. Presenting symptoms included pain (71%), nausea (57%), and vomiting (43%). Six patients initially underwent duodenal lowering, whereas one patient underwent duodenoduodenostomy. One patient underwent adhesiolysis for bowel obstruction in the early postoperative period. All patients had symptom resolution at a postoperative follow-up of 22 d (IQR, 15, 45). Two patients had symptom recurrence, and one patient required reoperation. Six patients completed the survey at a median of 2.3 y (IQR, 1.7, 3.2) postoperatively, of which four underwent duodenal lowering. Of these, 75% (n = 3) were asymptomatic. One patient with recurrence reported occasional nausea and emesis but has not required additional surgery. CONCLUSIONS: Release of the ligament of Treitz with duodenal lowering results in resolution of symptoms in 75% of patients. This operative approach may be considered before performing more complex operations for SMAS.

Analyzing a follow-up needs assessment: Increased use of internet-based APSA educational programs by pediatric surgeons.

PURPOSE: Needs assessment is a critical component of educational program design. Follow-up is important for improvement. Two electronic educational programs, Exam-based Pediatric surgery Educational Reference Tool (ExPERT) and Pediatric Surgery Not a Textbook (NaT), offered by the American Pediatric Surgical Association (APSA) have been functional for over three years, allowing for follow-up assessment. METHODS: A 22-question survey was distributed via email to APSA members. Questions included practice demographics, learning preferences and APSA material use. Mann-Whitney analysis was performed (p<0.05). RESULTS: 294 members responded. 43% were in academic practice with a pediatric surgery fellowship. Top preferences for obtaining/maintaining medical knowledge were national meetings (27%), ExPERT (24%), and the NaT (20%). Comparatively, in a 2014 assessment, electronic programs were less desired (16%). Cost was cited by >1/3 for not subscribing to ExPERT or NaT. Question discussions were often read regardless of response. >86% would subscribe to APSA resources if there were no CME requirement. The most frequently cited knowledge gap was fetal therapy (30%). CONCLUSIONS: This is the first publication documenting increased acceptance of electronic educational platforms for pediatric surgeons. Well-utilized and valued, the data justify and encourage continued development of electronic educational resources. Room for improvement exists in affordability, knowledge gaps, and individualizing curriculum development. LEVEL OF EVIDENCE: IV.

Postoperative pain control modalities for pectus excavatum repair: A prospective observational study of cryoablation compared to results of a randomized trial of epidural vs patient-controlled analgesia.

BACKGROUND: Pain following bar placement for pectus excavatum is the dominant factor post-operatively and determines length of stay (LOS). We recently adopted intercostal cryoablation as our preferred method of pain control following minimally invasive pectus excavatum repair. We compared the outcomes of cryoablation to results of a recently concluded trial of epidural (EPI) and patient-controlled analgesia (PCA) protocols. METHODS: We conducted a prospective observational study of patients undergoing bar placement for pectus excavatum using intercostal cryoablation. Results are reported and compared with those of a randomized trial comparing EPI with PCA. Comparisons of medians were performed using Kruskal-Wallis H tests with alpha 0.05. RESULTS: Thirty-five patients were treated with cryoablation compared to 32 epidural and 33 PCA patients from the trial. Cryoablation was associated with longer operating time (101 min, versus 58 and 57 min for epidural and PCA groups, p < 0.01), resulted in less time to pain control with oral medication (21 h, versus 72 and 67 h, p < 0.01), and decreased LOS (1 day, versus 4.3 and 4.2 days, p < 0.01). CONCLUSION: Intercostal cryoablation during minimally invasive pectus excavatum repair reduces LOS and perioperative opioid consumption compared with both EPI and PCA. LEVEL OF EVIDENCE: II.

Outcomes Following Dynamic Compression Bracing for Pectus Carinatum.

Introduction: Children with pectus carinatum (PC) are particularly vulnerable to psychosocial effects of poor body image, even though they may not experience physical symptoms. Nonoperative treatment with orthotic bracing is effective in PC correction. We describe our experience with dynamic compression bracing (DCB) for PC patients and their satisfaction with bracing. Materials and Methods: Prospective institutional data of patients undergoing DCB from July 2011 to June 2018 were reviewed and analyzed for those who entered the retainer mode after correction, defined by a correction pressure of <1 psi. A telephone survey was conducted regarding their bracing experience and satisfaction with the outcome on a scale of 1-10. Results: Of 460 PC patients, 144 reached the retainer mode. Median time to retainer mode was 5.5 months. There was no statistically significant relationship between initial correction pressure or carinatum height and time to retainer mode (P = .08 and P = .10, respectively). Fifty-seven percent were compliant with brace use, and median time to retainer mode in this subset was significantly shorter than noncompliant patients (3.5 months versus 10 months, P < .001). Fifty-three percent responded to the survey 13 months [interquartile ratios 3, 33] after the last clinic visit. The main barrier to compliance with wearing the brace was discomfort (37%), while the main motivation for compliance was appearance (58%). All endorsed bracing as worthwhile, with 94% reporting a satisfaction rating of 8 or greater for the correction outcome. Conclusion: DCB is effective in achieving correction of PC in compliant patients. Regardless of time to retainer mode, patients reported high satisfaction with bracing.
