RESUMEN
BACKGROUND: Men with high-risk prostate cancer undergoing surgery likely recur due to failure to completely excise regional and/or local disease. OBJECTIVE: The first-in-human evaluation of safety, pharmacokinetics, and exploratory efficacy of IS-002, a novel near-infrared prostate-specific membrane antigen (PSMA)-targeted fluorescence imaging agent, designed for intraoperative prostate cancer visualization. DESIGN, SETTING, AND PARTICIPANTS: A phase 1, single-center, dose-escalation study was conducted in 24 men with high-risk prostate cancer scheduled for robotic-assisted radical prostatectomy with (extended) pelvic lymph node dissection using the da Vinci surgical system. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Adverse events (AEs), vital signs, complete blood count, complete metabolic panel, urinalysis, and electrocardiogram were assessed over a 14-d period and compared with baseline. The pharmacokinetic profile of IS-002 was determined. Diagnostic accuracy was assessed for exploratory efficacy. RESULTS AND LIMITATIONS: AEs predominantly included discoloration of urine (n = 22/24; expected, related, grade 1). There were no grade ≥2 AEs. IS-002 Cmax and area under the curve increased with increasing dose. Plasma concentrations declined rapidly in a biphasic manner, with the median terminal half-lives ranging from 5.0 to 7.6 h, independent of dose and renal function. At 25 µg/kg, the exploratory efficacy readouts for the negative and positive predictive values were, 97% and 45% for lymph nodes, and 100% and 80% for residual/locoregional disease detection, respectively. CONCLUSIONS: IS-002 is safe and well tolerated, and has the potential to enable intraoperative tumor detection that could not be identified using standard imaging. PATIENT SUMMARY: IS-002 is a new imaging agent that specifically targets the prostate-specific membrane antigen receptor. In this study, we tested IS-002 for the first time in men with high-risk prostate cancer undergoing surgery and found that IS-002 is safe, is cleared from the body quickly, and potentially allows identification of prostate cancer in areas that would not be identified by conventional white light imaging.

BACKGROUND: The omental flap has numerous extraperitoneal applications in reconstruction and revascularization given its favorable immunologic and angiogenic properties. In patients with Moyamoya disease, cerebral revascularization using a pedicled omental flap has proven to be a viable option following direct revascularization procedures. Historically, harvesting omentum involved laparotomy with the associated risk of complications; herein we describe outcomes from a 10-year experience of laparoscopic harvesting of pedicled omental flap for cerebral revascularization in Moyamoya patients. METHODS: A retrospective chart review was performed of all patients with Moyamoya disease who underwent laparoscopic omental cerebral transposition between 2011 and 2021. Intraoperative and postoperative complications, length of stay (LOS), and outcomes at follow-up were analyzed. RESULTS: Twenty-one patients underwent the procedure during the study period. Three intraoperative complications occurred (one segmental transverse colectomy for mesenteric injury, one converted to omental free flap, and one requiring micro anastomosis). Average overall LOS was 6 ± 6 days, with 3 ± 3.5 days in the ICU (mean±SD). Following discharge, complications included epigastric incisional hernia at the graft fascial exit site, recurrent neck pain at subcutaneous tunneling site, and partial scalp necrosis. One patient required subsequent direct bypass seven months after the initial procedure owing to the progression of the disease. All other patients had partial or complete resolution of symptoms. CONCLUSION: Our retrospective observational study indicates that laparoscopic pedicled omental flap mobilization and transposition is a safe and effective method of indirect cerebral revascularization in patients with Moyamoya disease. LEVEL OF EVIDENCE: N/A.

RESUMEN
BACKGROUND: Total colonic and small bowel aganglionosis (TCSA) occurs in less than 1% of all Hirschsprung's disease patients. Currently, the mainstay of treatment is surgery. However, in patients with TCSA, functional outcomes are often poor. A characteristic transition zone in TCSA can be difficult to identify which may complicate surgery and may often require multiple operations. CASE PRESENTATION: We present the case of a male infant who was diagnosed with biopsy-proven total colonic aganglionosis with extensive small bowel involvement as a neonate. The patient was diverted at one month of age based on leveling biopsies at 10 cm from the Ligament of Treitz. At 7 months of age, during stoma revision for a prolapsed stoma, intra-operative peristalsis was observed in nearly the entire length of the previously aganglionic bowel, and subsequent biopsies demonstrated the appearance of mature ganglion cells in a previously aganglionic segment. CONCLUSIONS: TCSA remains a major challenge for pediatric surgeons. Our case introduces new controversy to our understanding of aganglionosis. Our observations warrant further research into the possibility of post-natal ganglion maturation and encourage surgeons to consider a more conservative surgical approach.

PURPOSE: Benign masses of the eyebrow and forehead are common in pediatric patients and can result in facial asymmetry, discomfort, or super-infection. Excision is classically conducted via an incision directly over the mass, which can produce sub-optimal cosmesis. Recently, an endoscopic approach using pediatric brow-lift equipment has been adopted. We reviewed our center's experience with endoscopic removal of benign facial lesions and compared these cases with an equivalent series of open cases. MATERIALS AND METHODS: A retrospective chart review was conducted to identify pediatric cases of endoscopic and open removal of benign eyebrow or forehead lesions at our institution from 2009 to 2016. Clinical and cosmetic outcomes were reviewed. RESULTS: A total of 40 endoscopic and 25 open cases of excision of benign facial lesions in children were identified. For the patients who underwent endoscopic excision, the majority (85%) presented with a cyst located at the eyebrow. Histologic examination revealed 36 dermoid cysts (90%), 2 epidermal cysts, and 2 pilomatrixomas. Of the 36 cases with post-operative follow-up, 32 patients (89%) had an uncomplicated recovery with good cosmesis. Two patients had an eyebrow droop that resolved without intervention. One patient had localized numbness overlying the site, but no motor deficits. One patient presented with a recurrent dermoid cyst that required open resection. For the patients who underwent open excision, the majority (52%) had dermoid cysts located at the eyebrow. Of the 22 cases with follow-up, 20 of the patients had an uncomplicated recovery (90%). Comparing the rate of complications, there was no statistically significant difference between the two groups (P = 1.0). CONCLUSION: Endoscopic excision of benign forehead and eyebrow lesions in pediatric patients is feasible and yields excellent cosmetic results. When compared with open excision, complication rates are similar between both approaches and a facial scar can be avoided with an endoscopic approach.

BACKGROUND: Sutureless gastroschisis repair involves covering the abdominal wall defect with the umbilical cord or a synthetic dressing to allow closure by secondary intention. No randomized studies have described the outcomes of this technique. Our objective was to prospectively compare short-term outcomes of sutureless vs sutured closure in a randomized fashion. STUDY DESIGN: We recruited patients who presented with gastroschisis between 2009 and 2014 and were randomized into either sutureless or sutured treatment groups. Patients with complicated gastroschisis (stricture, perforation, and ischemia) were excluded. Predefined ventilation, feeding, and dressing change protocols were instituted. Primary outcomes were time to extubation and time to full feeds. Secondary outcomes included time to discharge and rate of complications. Data were analyzed using Fisher's exact or t-tests using a p value ≤ 0.05. Factors associated with increased time to discharge were estimated using multivariate analyses. RESULTS: Thirty-nine patients were enrolled, 19 to sutureless and 20 to sutured repair. There was no statistical difference in time to extubation (sutureless 1.89 vs sutured 3.15 days; p = 0.061). The sutureless group had a significant increase in mean time to full feeds (45.1 vs 27.8 days; p = 0.031) and mean time to discharge (49.3 vs 31.4 days; p = 0.016). Complication rates were similar in both groups. Multivariate regression modeling showed that an increase in time to discharge was independently associated with sutureless repair, feeding complications, and sepsis. CONCLUSIONS: Sutureless repair of uncomplicated gastroschisis can be performed safely, however, it is associated with a significant increase in time to full feeds and time to discharge.

Background. The objective of this study was to determine whether female surgical residents underestimate their surgical abilities relative to males on a standardized test of laparoscopic skill. Methods. Twenty-six male and female general surgery residents and 25 female obstetrics and gynecology residents at two academic centers were asked to predict their score prior to undergoing the Fundamentals of Laparoscopic Surgery standardized skills exam. Actual and predicted score as well as delta values (predicted score minus actual score) were compared between residents. Multivariate linear regression was used to determine variables associated with predicted score, actual score, and delta scores. Results. There was no difference in actual score based on residency or gender. Predicted scores, however, were significantly lower in female versus male general surgery residents (25.8 ± 13.3 versus 56.0 ± 16.0; p < 0.01) and in female obstetrics and gynecology residents versus male general surgery residents (mean difference 20.9, 95% CI 11.6-34.8; p < 0.01). Male residents more accurately predicted their scores while female residents significantly underestimated their scores. Conclusion. Gender differences in estimating surgical ability exist that do not reflect actual differences in performance. This finding needs to be considered when structuring mentorship in surgical training programs.
RESUMEN
INTRODUCTION: An abundance of angiogenic and immunologic factors makes the omentum an ideal tissue for reconstruction and revascularization of a variety of extraperitoneal wounds and defects. Omental harvesting was historically performed through a large laparotomy and subcutaneous tunneling to the site of disease. Several complications of the open procedure including abdominal wound infection, fascial dehiscence, ventral hernia, and postoperative ileus have been described. The use of laparoscopy to harvest the omentum has the potential to reduce such complications. We describe the surgical technique and outcomes of a series of patients undergoing laparoscopic pedicled omental flap mobilization for cerebral revascularization in moyamoya disease. METHODS: A retrospective chart review of all patients undergoing laparoscopic omental cerebral transposition for moyamoya disease between 2011 and 2014 was performed. Clinical indication, surgical technique, operative times, complications, and outcomes at follow-up were reviewed. RESULTS: A total of 7 children underwent the procedure. The general surgery team performed laparoscopic omental mobilization, extraperitonealization, and subcutaneous tunneling, while the neurosurgical team performed craniotomy and cerebral application of the graft. The patients were followed postoperatively with clinic visits and angiography. There was one intraoperative complication (colon injury) and one postoperative complication (intermittent omental hernia at fascial defect for pedicle). All patients had partial to complete symptomatic resolution and demonstrated adequate intracranial revascularization on angiography. CONCLUSION: Laparoscopic omental pedicle flap mobilization and subcutaneous transposition is feasible in children who require salvage cerebral revascularization for moyamoya disease. The procedure should be considered for other conditions requiring extraperitoneal revascularization.

PURPOSE: The purpose of this study was to define the hematologic response to total splenectomy (TS) or partial splenectomy (PS) in children with hereditary spherocytosis (HS) or sickle cell disease (SCD). METHODS: The Splenectomy in Congenital Hemolytic Anemia (SICHA) consortium registry collected hematologic outcomes of children with CHA undergoing TS or PS to 1 year after surgery. Using random effects mixed modeling, we evaluated the association of operative type with change in hemoglobin, reticulocyte counts, and bilirubin. We also compared laparoscopic to open splenectomy. RESULTS: The analysis included 130 children, with 62.3% (n=81) undergoing TS. For children with HS, all hematologic measures improved after TS, including a 4.1g/dl increase in hemoglobin. Hematologic parameters also improved after PS, although the response was less robust (hemoglobin increase 2.4 g/dl, p<0.001). For children with SCD, there was no change in hemoglobin. Laparoscopy was not associated with differences in hematologic outcomes compared to open. TS and laparoscopy were associated with shorter length of stay. CONCLUSION: Children with HS have an excellent hematologic response after TS or PS, although the hematologic response is more robust following TS. Children with SCD have smaller changes in their hematologic parameters. These data offer guidance to families and clinicians considering TS or PS.

BACKGROUND: Laparoscopic transcutaneous inguinal hernia repair in children may reduce postoperative pain, improve cosmesis, allow for less manipulation of the cord structures, and offer easy access to the contralateral groin. However, there is concern for unacceptably high recurrence rates when the procedure is generalized. To address this increase in recurrence, in 2011 we described in this journal a modification of the laparoscopic transcutaneous technique that replicates high transfixation ligature of the hernia sac with the aim of inducing more secure healing, preventing suture slippage, and distributing tension across two suture passes. We now describe our long-term follow-up of this novel repair. METHODS: After obtaining IRB approval, a retrospective chart review and phone follow-up were performed on all patients who underwent laparoscopic transfixation ligature hernia repair between October 2009 and August 2014 (including further follow-up of the 21 patients reviewed in the 2011 report of this technique). Data collection included demographics, laterality of hernia, evidence of recurrence, complications, and time to follow-up. RESULTS: Median follow-up was 24 months (range 2-52 months). Three pediatric surgeons performed 216 laparoscopic transfixation ligature repairs on 166 patients. DEMOGRAPHICS: mean age 29.5 months (range 1-192 months); male 67.2% and female 32.8%; 4.2% of patients were premature at operation. Repairs were bilateral in 42% of patients, right sided in 34%, and left sided in 24%. Three patients together experienced 4 recurrences, for an overall recurrence rate of 1.8%. Two of the recurrences occurred in a 2-month old syndromic patient with severe congenital heart disease who recurred twice after laparoscopic transfixation ligature repair then subsequently failed an attempt at open repair. Excluding this one outlier patient, the recurrence rate was 0.9%. The complication rate was 1.7% (3 hydroceles and 1 inguinal hematoma; all resolved spontaneously). CONCLUSION: Laparoscopic high transfixation ligature hernia repair can be adopted by surgeons with basic laparoscopic skills, and result in excellent outcomes with acceptable recurrence rates.

BACKGROUND AND OBJECTIVES: Although several standardized definitions for AKI have been developed, no consensus exists regarding which to use in children. This study applied the Pediatric RIFLE (pRIFLE), AKI Network (AKIN), and Kidney Disease Improving Global Outcomes (KDIGO) criteria to an anonymized cohort of hospitalizations extracted from the electronic medical record to compare AKI incidence and outcomes in intensive care unit (ICU) and non-ICU pediatric populations. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: Observational, electronic medical record-enabled study of 14,795 hospitalizations at the Lucile Packard Children's Hospital between 2006 and 2010. AKI and AKI severity stage were defined by the pRIFLE, AKIN, and KDIGO definitions according to creatinine change criteria; urine output criteria were not used. The incidences of AKI and each AKI stage were calculated for each classification system. All-cause, in-hospital mortality and total hospital length of stay (LOS) were compared at each subsequent AKI stage by Fisher exact and Kolmogorov-Smirnov tests, respectively. RESULTS: AKI incidences across the cohort according to pRIFLE, AKIN, and KDIGO were 51.1%, 37.3%, and 40.3%. Mortality was higher among patients with AKI across all definitions (pRIFLE, 2.3%; AKIN, 2.7%; KDIGO, 2.5%; P<0.001 versus no AKI [0.8%-1.0%]). Within the ICU, pRIFLE, AKIN, and KDIGO demonstrated progressively higher mortality at each AKI severity stage; AKI was not associated with mortality outside the ICU by any definition. Both in and outside the ICU, AKI was associated with significantly higher LOS at each AKI severity stage across all three definitions (P<0.001). Definitions resulted in differences in diagnosis and staging of AKI; staging agreement ranged from 76.7% to 92.5%. CONCLUSIONS: Application of the three definitions led to differences in AKI incidence and staging. AKI was associated with greater mortality and LOS in the ICU and greater LOS outside the ICU. All three definitions demonstrated excellent interstage discrimination. While each definition offers advantages, these results underscore the need to adopt a single, universal AKI definition.

PURPOSE: To compare fixation stability and fixation loss between the Humphrey Field Analyzer (HVF, static fixation target) and the RareBit computer-based perimeter (RBP, kinetic fixation target) during visual field testing. METHODS: Fourteen healthy volunteer subjects wore an ASL Mobile Gaze Tracker as they completed HVF 10-2 and RareBit central field tests in a random order. Fixation stability, defined as the average distance from the fixation target to the subject's gaze location, was calculated using data from the processed video capture. Fixation loss, defined as eye closure or a deviation of >20 degrees from the fixation target, was also measured. All subjects were surveyed regarding test preference. RESULTS: Use of the RBP kinetic target was associated with 18% improved fixation stability compared with the HVF static target (P=0.02). Nine of 14 study subjects demonstrated better fixation with RBP compared with HVF. Subjects demonstrated decreased fixation loss during RBP (0.9 s) compared with HVF (10.0 s) (P=0.002). Eighty-six percent of study subjects preferred RBP over HVF. CONCLUSIONS: Use of the RBP kinetic fixation target is associated with consistent fixation stability and decreased fixation loss compared with the HVF static target. This improvement in fixation stability may result from decreased perception interference (Ganzfeld, Troxler, and binocular rivalry effects), and may help account for the greater comfort reported with RBP compared with HVF.

The outcomes of children with congenital hemolytic anemia (CHA) undergoing total splenectomy (TS) or partial splenectomy (PS) remain unclear. In this study, we collected data from 100 children with CHA who underwent TS or PS from 2005 to 2013 at 16 sites in the Splenectomy in Congenital Hemolytic Anemia (SICHA) consortium using a patient registry. We analyzed demographics and baseline clinical status, operative details, and outcomes at 4, 24, and 52 weeks after surgery. Results were summarized as hematologic outcomes, short-term adverse events (AEs) (≤30 days after surgery), and long-term AEs (31-365 days after surgery). For children with hereditary spherocytosis, after surgery there was an increase in hemoglobin (baseline 10.1 ± 1.8 g/dl, 52 week 12.8 ± 1.6 g/dl; mean ± SD), decrease in reticulocyte and bilirubin as well as control of symptoms. Children with sickle cell disease had control of clinical symptoms after surgery, but had no change in hematologic parameters. There was an 11% rate of short-term AEs and 11% rate of long-term AEs. As we accumulate more subjects and longer follow-up, use of a patient registry should enhance our capacity for clinical trials and engage all stakeholders in the decision-making process.

CONTEXT: Birth and immediate postpartum period pose many challenges for the newborn. The neonatal mortality rates are high in India, whereas the breastfeeding rates are still low. Hence, need exists for a simple and easily applicable intervention, which may counter these challenges. AIMS: The present study was undertaken to evaluate the effects of very early skin-to-skin contact (SSC), in term babies with their mothers, on success of breastfeeding and neonatal well-being. SETTINGS AND DESIGN: Randomized control trial conducted over 2 years' period in a tertiary care hospital. MATERIALS AND METHODS: Healthy babies delivered normally were included. Very early SSC between mothers and their newborns was initiated in the study group. We studied effective suckling (using modified infant breastfeeding assessment tool [IBFAT]), breastfeeding status at 6 weeks, maternal satisfaction, thermal regulation, baby's weight and morbidity. STATISTICAL ANALYSIS: T-test, Pearson Chi-square test and non-parametric Mann-Whitney test were used through relevant Windows SPSS software version 16.0. RESULTS: We observed that SSC contributed to better suckling competence as measured by IBFAT score (P < 0.0001). More babies in the SSC group were exclusively breastfed at first follow-up visit (P = 0.002) and at 6 weeks (P < 0.0001). SSC led to higher maternal satisfaction rates, better temperature gain in immediate post-partum period, lesser weight loss was at discharge and at first follow-up (all P < 0.0001) and lesser morbidity than the study group (P = 0.006). CONCLUSION: Very early SSC is an effective intervention that improves baby's suckling competence, maternal satisfaction, breastfeeding rates and temperature control and weight patterns.

BACKGROUND: Patients with moyamoya disease and progressive neurological deterioration despite previous revascularization pose a major treatment challenge. Many have exhausted typical sources for bypass or have ischemia in areas that are difficult to reach with an indirect pedicled flap. Omental-cranial transposition has been an effective, but sparingly used technique because of its associated morbidity. OBJECTIVE: We have refined a laparoscopic method of harvesting an omental flap that preserves its gastroepiploic arterial supply. METHODS: The pedicled omentum can be lengthened as needed by dividing it between the vascular arcades. It is transposed to the brain via skip incisions. The flap can be trimmed or stretched to cover ischemic areas of the brain. The cranial exposure is performed in parallel with pediatric surgeons. We performed this technique in 3 pediatric patients with moyamoya disease (aged 5-12 years) with previous superficial temporal artery to middle cerebral artery bypasses and progressive ischemic symptoms. In 1 patient, we transposed omentum to both hemispheres. RESULTS: Blood loss ranged from 75 to 250 mL. After surgery, patients immediately tolerated a diet and were discharged in 3 to 5 days. The ischemic symptoms of all 3 children resolved within 3 months postoperatively. Magnetic resonance imaging at 1 year showed improved perfusion and no new infarcts. Angiography showed excellent revascularization of targeted areas and patency of the donor gastroepiploic artery. CONCLUSION: Laparoscopic omental harvest for cranial-omental transposition can be performed efficiently and safely. Patients with moyamoya disease appear to tolerate this technique much better than laparotomy. With this method, we can achieve excellent angiographic revascularization and resolution of ischemic symptoms.

BACKGROUND: The purpose of this prospective randomized study was to compare landmark- to ultrasound-guided central venous access when performed by pediatric surgeons. The American College of Surgeons advocates for use of ultrasound in central venous catheter placement; however, this is not universally embraced by pediatric surgeons. Complication risk correlates positively with number of venous cannulation attempts. STUDY DESIGN: With IRB approval, a randomized prospective study of children under 18 years of age undergoing tunneled central venous catheter placement was performed. Patient accrual was based on power analysis. Exclusion criteria included known nonpatency of a central vein or coagulopathy. After randomization, the patients were assigned to either ultrasound-guided internal jugular vein access or landmark-guided subclavian/internal jugular vein access. The primary outcomes measure was number of attempts at venous cannulation. Secondary outcomes measures included: access times, number of arterial punctures, and other complications. Continuous variables were compared using 2-tailed Student's t-test. Discrete variables were analyzed with chi-square. Significance was defined as p < 0.05. RESULTS: There were 150 patients enrolled between April 2008 and September 2011. There was no difference when comparing demographic data. Success at first attempt was achieved in 65% of patients in the ultrasound group vs 45% in the landmark group (p = 0.021). Success within 3 attempts was achieved in 95% of ultrasound group vs 74% of landmark group (p = 0.0001). CONCLUSIONS: Ultrasound reduced the number of cannulation attempts necessary for venous access. This indicates a potential to reduce complications when ultrasound is used by pediatric surgeons.

BACKGROUND/PURPOSE: Chest wall reconstruction in children is typically accomplished with either primary tissue repair or synthetic mesh prostheses. Primary tissue repair has been associated with high rates of scoliosis, whereas synthetic prostheses necessitate the placement of a permanent foreign body in growing children. This report describes the use of biologic mesh (Permacol; Covidien, Mansfield, MA) as an alternative to both tissue repair and synthetic prostheses in pediatric chest wall reconstruction. METHODS: A retrospective chart review was performed identifying patients undergoing chest wall reconstruction with biologic mesh at our tertiary referral children's hospital between 2007 and 2011. Data collection included patient demographics, indication for chest wall resection, number of ribs resected, the administration of postoperative radiation, length of follow-up, postoperative complications, and the degree of spinal angulation (preoperatively and at most recent follow-up). RESULTS: Five patients (age, 9.0-21.7 years; mean, 15.4 years) underwent resection for primary chest wall malignancy followed by reconstruction with biologic mesh (Permacol) during the study period. There were no postoperative mesh-related complications, and none of the patients developed clinically significant scoliosis (follow-up, 1.1-2.6 years; mean 1.9 years). CONCLUSION: Biologic mesh offers a safe and dependable alternative to both primary tissue repair and synthetic mesh in pediatric patients undergoing chest wall reconstruction.

BACKGROUND: Intestinal malrotation in the newborn is usually diagnosed after signs of intestinal obstruction, such as bilious emesis, and corrected with the Ladd procedure. OBJECTIVES: The objective of this report is to describe the presentation of severe cases of midgut volvulus presenting in infancy, and to discuss the characteristics of these cases. CASE REPORT: We performed a 7-year review at our institution and present two cases of catastrophic midgut volvulus presenting in the post-neonatal period, ending in death soon after the onset of symptoms. These two patients also had significant laboratory abnormalities compared to patients with more typical presentations resulting in favorable outcomes. CONCLUSIONS: Although most cases of intestinal malrotation in infancy can be treated successfully, in some circumstances, patients' symptoms may not be detected early enough for effective treatment, and therefore may result in catastrophic midgut volvulus and death.

Laparoscopic splenectomy was first described in children in 1993. Since then, it has become a commonly performed procedure in children because of reduced discomfort and hospitalization and significantly improved cosmesis compared with the open approach. With the advent of single-site laparoscopic surgery, it is only natural that this approach be used for splenectomy. This article will describe the reasons that the single-site approach might be useful for splenectomy and also the technique used at the author's institution. Moreover, a brief review of the current literature in children will be presented.
