OBJECTIVES/OBJECTIVE:To evaluate outcomes after surgical ligation (SL) of patent ductus arteriosus (PDA) in premature, extremely low birth weight (ELBW) infants. BACKGROUND:Optimal management of PDA in this specialized population remains undefined. Currently, surgical therapy is largely reserved for infants failing medical management. To date, a large-scale, risk-matched population-based study has not been performed to evaluate differences in mortality and resource utilization. METHODS:Data on identified premature (<37 weeks) and ELBW (<1000  g) infants with PDA (International Classification of Diseases, 9th revision, Clinical Modification, 747.0) and respiratory distress (769) were obtained from Kids' Inpatient Database (2003-2009). RESULTS:Overall, 12,470 cases were identified, with 3008 undergoing SL. Propensity score-matched analysis of 1620 SL versus 1584 non-SL found reduced mortality (15% vs 26%) and more routine disposition (48% vs 41%) for SL (P < 0.001). SL had longer length of stay and higher total cost (P < 0.001). On multivariate analysis, SL mortality predictors were necrotizing enterocolitis (NEC; surgical odds ratio, 5.95; medical odds ratio, 4.42) and sepsis (3.43) (P < 0.006). Length of stay increased with bronchopulmonary dysplasia (BPD; 1.77), whereas total cost increased with surgical NEC (1.82) and sepsis (1.26) (P < 0.04). Non-SL mortality predictors were NEC (surgical, 76.3; medical, 6.17), sepsis (2.66), and intraventricular hemorrhage (1.97) (P < 0.005). Length of stay increased with BPD (2.92) and NEC (surgical, 2.04; medical, 1.28) (P < 0.03). Total cost increased with surgical NEC (2.06), medical NEC (1.57), sepsis (1.43), and BPD (1.30) (P < 0.001). CONCLUSIONS:Propensity score-matched analysis demonstrates reduced mortality in premature/ELBW infants with SL for PDA. NEC and sepsis are predictors of mortality and resource utilization.

OBJECTIVE:The use of laparoscopic sleeve gastrectomy (LSG) has risen steadily as a treatment for adolescents with obesity. This study determined whether obstructive biliary complications after rapid, LSG-related weight loss occur similarly in adolescents compared with adults. METHODS:Between 2010 and 2019, 309 patients underwent LSG. Demographics and clinical factors, including pre- and perioperative BMI and weight changes, were included. RESULTS:. Preoperative excess BMI loss was 7.1% (SD 11.3%). An ultrasound revealed gallstones (71%) and sludge or crystals (12%). Eighteen patients underwent cholecystectomy between 4 weeks and 29 months after LSG. CONCLUSIONS:Pediatric patients present with BD at a similar rate after LSG compared with adults. The majority of adolescents, however, manifest with AP. Thus, pancreatitis should be high on the differential diagnosis list when evaluating post-LSG abdominal symptoms. Additional studies are warranted to elucidate the pathophysiology of post-LSG AP for prevention in the future because its etiology may or may not be solely related to BD.

BACKGROUND:To evaluate peritoneal drainage (PD) and laparotomy ± resection/ostomy (LAP) as initial approaches to the surgical management of necrotizing enterocolitis (NEC) in premature, extremely low birth weight (ELBW) infants. METHODS:Kids' Inpatient Database (2003-2012) was searched for cases of NEC (International Classification of Diseases, ninth revision, Clinical Modification [ICD-9-CM] 777.5x) in premature (<37 weeks), extremely low birth weight (<1000 g) infants. Infants were admitted at <28 days of life. Propensity score (PS)-matched analyses were performed, using end points of hospital mortality, length of stay (LOS), and cost of hospitalization. Cases were matched 1:1 on 48 confounding variables (demographic, clinical, and hospital characteristics and 39 comorbidities). RESULTS:On PS-matched comparison, PD had higher survival versus LAP, P = 0.0009. LOS and cost were higher for PD versus LAP, P < 0.003. Survival rates did not differ between PD + LAP and PD-only treatments. LOS and cost were higher for PD + LAP versus PD-only, P < 0.02. PD + LAP infants had higher survival versus LAP, P = 0.0193. LOS and cost were higher for PD + LAP, P < 0.005. CONCLUSIONS:A risk-adjusted PS-matched analysis of operative management in premature, ELBW infants with NEC found higher survival rates associated with PD placement versus LAP, whether PD was used as definitive treatment or with subsequent LAP even after controlling for potential contributors to selection bias (i.e., stability influencing management preference).

BACKGROUND:Body contouring surgery (BCS) is a common postoperative trajectory for adults following bariatric surgery, yet research on its application to adolescents is lacking. This scoping review aimed to map the available literature on quality of life (QoL) and potential for BCS in adolescents after bariatric surgery. METHODS:This review followed the Joanna Briggs Institute (JBI) guidance for scoping reviews and is reported in accordance with the PRISMA extension for Scoping Reviews (PRISMA-ScR). Three electronic databases were queried for studies regarding QoL and BCS in adolescents following bariatric surgery within the last 20 years. A descriptive and thematic analysis was conducted. RESULTS:Twenty-three studies met inclusion criteria. A total of 19 (82.6%) evaluated QoL and 4 (17.4%) explored the role of BCS in adolescents following bariatric surgery. The most common method of data collection was prospective study (65.2%). Two themes were described: QoL after bariatric surgery, which expressed improvement in several domains within 6 months, and role for BCS, which showed high interest in addressing residual excess skin and appearance. Gaps in the literature were identified, including a need for studies exploring mediators of QoL, predictors of compliance, and outcomes of BCS. CONCLUSIONS:Studies describing residual symptoms and BCS in adolescents following bariatric surgery are lacking. BCS may complement bariatric surgery, but further research must be conducted to assess its safety in adolescents. By addressing the research gaps described in this review, physicians may have a better understanding of the needs of this population and how to counsel them.

BACKGROUND:Management of infant perianal disease, including perianal abscess and fistula-in- ano (FIA), remains controversial. There is lack of consensus regarding the risks and benefits of operative and non-operative approaches. METHODS:The American Pediatric Surgical Association Outcomes and Evidence Based Practice Committee created a priori consensus-based questions regarding the various approaches to management of perianal abscess and FIA in infants. A comprehensive search strategy was created, and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were used to identify and review relevant articles and answer the established questions. RESULTS:Over 2460 titles and abstracts were screened to identify 31 manuscripts describing the expected course of perianal disease when managed with nonoperative management (NOM) strategies (such as hygiene, sitz baths, and systemic antibiotics), operative intervention for abscess only (incision and drainage (I&D)) or direct surgical management of the FIA (e.g. upfront fistulotomy). Initial failure of NOM is approximately 37.5 %. Recurrence rate after initial success with NOM or I&D is approximately 21 % and 24 %, respectively. The rate of FIA development is approximately 21 % after NOM and 20 % after I&D. Recurrence after operative management of FIA, regardless of approach, is 7 %. Time to complete resolution varies widely and does not appear to differ based on treatment strategy. CONCLUSIONS:Both operative and non-operative approaches can be safely used in the management of perianal abscess and FIA but recurrence is common regardless of approach. Risks and benefits of each approach should be considered on a case-by-case basis. TYPE OF STUDY/METHODS:Systematic Review of level 3-4 studies. LEVEL OF EVIDENCE/METHODS:Level 4.

OBJECTIVE:Consensus on functional outcomes for anorectal malformations (ARM) is hindered by the heterogeneity of the available literature. Optimal patient counseling includes discussion of short- and long-term outcomes for bowel and urinary continence, sexual and psychosocial function, transitional care, and quality of life. This systematic review examines and summarizes the current literature available related to functional outcomes for children with ARM. METHODS:The American Pediatric Surgical Association Outcomes and Evidence Based Practice Committee drafted consensus-based questions regarding anorectal malformations. Pertinent articles from 1985 to 2021 were reviewed. RESULTS:More than 10,843 publications were reviewed with 109 being included in the final recommendations. Recommendations are primarily based on C-D levels of evidence. Continence and constipation rates were higher in patients with perineal fistula and rectovestibular fistula, although symptoms tended to improve as patients got older. Urological anomalies are common and longer term urologic surveillance protocols for patients with ARM need to be further outlined. Sexual and psychosocial issues are common, but ARM patients can have a good quality of life when gastrointestinal symptoms are minimized. Many of the problems associated with ARM can persist into adulthood, supporting structured care plans as patients transition to adult care. CONCLUSIONS:Evidence to support best practices and achieve optimal outcomes for patients with ARM is lacking for many aspects of care. Multi-institutional registries have begun to address management and prognosis for these patients. Prospective and comparative studies are needed to improve care and provide consensus guidelines for this complex patient population.

OBJECTIVE:Treatment of neonates with anorectal malformations (ARMs) can be challenging due to variability in anatomic definitions, multiple approaches to surgical management, and heterogeneity of reported outcomes. The purpose of this systematic review is to summarize existing evidence, identify treatment controversies, and provide guidelines for perioperative care. METHODS:The American Pediatric Surgical Association Outcomes and Evidence Based Practice Committee (OEBP) drafted five consensus-based questions regarding management of children with ARMs. These questions were related to categorization of ARMs and optimal methods and timing of surgical management. A comprehensive search strategy was performed, and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were used to perform the systematic review to attempt to answer five questions related to surgical care of ARM. RESULTS:A total of 10,843 publications were reviewed, of which 90 were included in final recommendations, and some publications addressed more than one question (question: 1 n = 6, 2 n = 63, n = 15, 4 n = 44). Studies contained largely heterogenous groups of ARMs, making direct comparison for each subtype challenging and therefore, no specific recommendation for optimal surgical approach based on outcomes can be made. Both loop and divided colostomy may be acceptable methods of fecal diversion for patients with a diagnosis of anorectal malformation, however, loop colostomies have higher rates of prolapse in the literature reviewed. In terms of timing of repair, there did not appear to be significant differences in outcomes between early and late repair groups. Clear and uniform definitions are needed in order to ensure similar populations of patients are compared moving forward. Recommendations are provided based primarily on A-D levels of evidence. CONCLUSIONS:Evidence-based best practices for ARMs are lacking for many aspects of care. Multi-institutional registries have made progress to address some of these gaps. Further prospective and comparative studies are needed to improve care and provide consensus guidelines for this complex patient population.

BACKGROUND:Significant variation in management strategies for lymphatic malformations (LMs) in children persists. The goal of this systematic review is to summarize outcomes for medical therapy, sclerotherapy, and surgery, and to provide evidence-based recommendations regarding the treatment. METHODS:Three questions regarding LM management were generated according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Publicly available databases were queried to identify articles published from January 1, 1990, to December 31, 2021. A consensus statement of recommendations was generated in response to each question. RESULTS:The initial search identified 9326 abstracts, each reviewed by two authors. A total of 600 abstracts met selection criteria for full manuscript review with 202 subsequently utilized for extraction of data. Medical therapy, such as sirolimus, can be used as an adjunct with percutaneous treatments or surgery, or for extensive LM. Sclerotherapy can achieve partial or complete response in over 90% of patients and is most effective for macrocystic lesions. Depending on the size, extent, and location of the malformation, surgery can be considered. CONCLUSION/CONCLUSIONS:Evidence supporting best practices for the safety and effectiveness of management for LMs is currently of moderate quality. Many patients benefit from multi-modal treatment determined by the extent and type of LM. A multidisciplinary approach is recommended to determine the optimal individualized treatment for each patient.

INTRODUCTION/BACKGROUND:The diagnosis and management of biliary dyskinesia in children and adolescents remains variable and controversial. The American Pediatric Surgical Association Outcomes and Evidence-Based Practice Committee (APSA OEBP) performed a systematic review of the literature to develop evidence-based recommendations. METHODS:Through an iterative process, the membership of the APSA OEBP developed five a priori questions focused on diagnostic criteria, indications for cholecystectomy, short and long-term outcomes, predictors of success/benefit, and outcomes of medical management. A systematic review was conducted, and articles were selected for review following Preferred Reporting Items for Systematic Review and Meta-analyses (PRISMA) guidelines. Risk of bias was assessed using Methodologic Index for Non-Randomized Studies (MINORS) criteria. The Oxford Levels of Evidence and Grades of Recommendation were utilized. RESULTS:The diagnostic criteria for biliary dyskinesia in children and adolescents are not clearly defined. Cholecystectomy may provide long-term partial or complete relief in some patients; however, there are no reliable predictors of symptom relief. Some patients may experience resolution of symptoms with non-operative management. CONCLUSIONS:Pediatric biliary dyskinesia remains an ill-defined clinical entity. Pediatric-specific guidelines are necessary to better characterize the condition, guide work-up, and provide management recommendations. Prospective studies are necessary to more reliably identify patients who may benefit from cholecystectomy. LEVEL OF EVIDENCE/METHODS:Level 3-4.

BACKGROUND:Adolescent obesity is multifactorial, but parental history is the most significant risk factor. Laparoscopic sleeve gastrectomy (LSG) is part of the multidisciplinary approach to adolescent weight loss. OBJECTIVE:We aimed to evaluate the effects of parental history of bariatric surgery, as well as age at time of operation, on adolescents who underwent LSG at our institution. METHODS:We performed a retrospective review of patients, aged 10 to 19 years, who underwent LSG from January 2010 to December 2019. The adolescent bariatric surgical dataset maintained by our group was used to obtain patient demographics, weight, body mass index (BMI), and parental history of bariatric surgery. RESULTS:Among 328 patients, 76 (23.2%) had parents who had previously undergone bariatric surgery. These patients were significantly heavier by weight (p = 0.012) at the time of operation but had no difference in postoperative weight loss. When all patients were compared by age at operation (< 16 years, n = 102, ≥ 16 years, n = 226), there were few differences in outcomes. CONCLUSIONS:LSG is an effective approach to surgical weight loss in adolescents. Patient age should not be a barrier to weight loss surgery, especially among patients with a parental history of obesity. By intervening at a younger age, the metabolic sequelae of obesity may be reduced.
