RESUMO
OBJECTIVE: The aim of this review was to review the ethical and multidisciplinary clinical challenges facing trauma surgeons when resuscitating patients presenting with penetrating brain injury (PBI) and multicavitary trauma. BACKGROUND: While there is a significant gap in the literature on managing PBI in patients presenting with multisystem trauma, recent data demonstrate that resuscitation and prognostic features for such patients remains poorly described, with trauma guidelines out of date in this field. METHODS: We reviewed a combination of recent multidisciplinary evidence-informed guidelines for PBI and coupled this with expert opinion from trauma, neurosurgery, neurocritical care, pediatric and transplant surgery, surgical ethics and importantly our community partners. RESULTS: Traditional prognostic signs utilized in traumatic brain injury may not be applicable to PBI with a multidisciplinary team approach suggested on a case-by-case basis. Even with no role for neurosurgical intervention, neurocritical care, and neurointerventional support may be warranted, in parallel to multicavitary operative intervention. Special considerations should be afforded for pediatric PBI. Ethical considerations center on providing the patient with the best chance of survival. Consideration of organ donation should be considered as part of the continuum of patient, proxy and family-centric support and care. Community input is crucial in guiding decision making or protocol establishment on an institutional level. CONCLUSIONS: Support of the patient after multicavitary PBI can be complex and is best addressed in a multidisciplinary fashion with extensive community involvement.

With the rise of the coronavirus disease 2019 (COVID-19) respiratory pandemic, there has been an increased need to consider the use of extracorporeal membrane oxygenation (ECMO) technology. In the early phases of the pandemic, adults constituted most of the critically ill patients, and ECMO management strategies were developed for use in this population. During the course of the pandemic, there has been a rise in the number of critically ill children infected with COVID-19. Although ECMO has been used in the care of pediatric patients for more than half a century, it has been challenging to apply the lessons learned from adult patients with COVID-19 directly to critically ill children for whom ECMO is under consideration. This article reviews ECMO technology and highlights a number of important changes in pediatric ECMO regarding those patients infected with COVID-19. [Pediatr Ann. 2022;51(7):e281-e285.].

OBJECTIVE: To evaluate an institutional practice change from an extracorporeal life support (ECLS) anticoagulation monitoring strategy of activated clotting time (ACT) alone to a multimodal strategy including ACT, activated partial thrombin time, heparin anti-factor-Xa, and thromboelastography. METHODS: This was a retrospective review of patients younger than 18 years on ECLS and heparin between January 2014 and June 2020 at a single institution. RESULTS: Twenty-seven patients used an ACT-directed strategy and 25 used a multimodal strategy. The ACT-directed group was on ECLS for a shorter median duration than the multimodal group (136 versus 164 hours; p = 0.046). There was a non-significant increase in major hemorrhage (85.1% versus 60%; p = 0.061) and a significantly higher incidence of central nervous system (CNS) hemorrhage in the ACT-directed group (29.6% versus 0%; p = 0.004). Rates of thrombosis were similar, with a median of 3 circuit changes per group (p = 0.921). The ACT-directed group had larger median heparin doses (55 versus 34 units/kg/hr; p < 0.001), required more dose adjustments per day (3.8 versus 1.7; p < 0.001), and had higher rates of heparin doses >50 units/kg/hr (62.9% versus 16%; p = 0.001). More anticoagulation parameters were supratherapeutic (p = 0.015) and fewer were therapeutic (p < 0.001) in the ACT-directed group. CONCLUSIONS: Patients with a multimodal strategy for monitoring anticoagulation during ECLS had lower rates of CNS hemorrhage and decreased need for large heparin doses of >50 units/kg/hr without an increase in clotting complications, compared with ACT-directed anticoagulation. Multimodal anticoagulation monitoring appears superior to ACT-only strategies and may reduce heparin exposure and risk of hemorrhagic complications for pediatric patients on ECLS.
RESUMO
BACKGROUND: Shock index, pediatric age adjusted (SIPA), has been widely applied in pediatric trauma but has limited precision because of the reference ranges used in its derivation. We hypothesized that a pediatric shock index (PSI) equation based on age-based vital signs would outperform SIPA. METHODS: A retrospective cohort of trauma patients aged 1 to 18 years from Trauma Quality Programs - Participant Use File 2010 to 2018 was performed. A random 70% training subset was used to derive Youden index-optimizing shock index (SI) cutoffs by age for blood transfusion within 4 hours. We used linear regression to derive equations representing the PSI cutoff for children 12 years or younger and 13 years or older. For children 13 years or older, the well-established SI of 0.9 remained optimal, consistent with SIPA and other indices. For children 12 years or younger in the 30% validation subset, we compared our age-based PSI to SIPA as predictors of early transfusion, mortality, pediatric intensive care unit admission, and injury severity score of ≥25. For bedside use, a simplified "rapid" pediatric shock index (rPSI) equation was also derived and compared with SIPA. RESULTS: A total of 439,699 patients aged 1 to 12 years met the inclusion criteria with 2,718 (1.3% of those with available outcome data) requiring transfusion within 4 hours of presentation. In the validation set, positive predictive values for early transfusion were higher for PSI (8.3%; 95% confidence interval [CI], 7.5-9.1%) and rPSI (6.3%; 95% CI, 5.7-6.9%) than SIPA (4.3%; 95% CI, 3.9-4.7%). For early transfusion, negative predictive values for both PSI (99.3%; 95% CI, 99.2-99.3%) and rPSI (99.3%; 95% CI, 99.2-99.4%) were similar to SIPA (99.4%; 95% CI, 99.3-99.4%). CONCLUSION: We derived the PSI and rPSI for use in pediatric trauma using empiric, age-based SI cutoffs. The PSI and rPSI achieved higher positive predictive values and similar negative predictive values to SIPA in predicting the need for early blood transfusion and mortality. LEVEL OF EVIDENCE: Prognostic/Epidemiological; level III.

P-glycoprotein (Pgp), a product of the multi-drug resistance gene MDR1a, is a broad specificity efflux ATP cassette transmembrane transporter that is predominantly expressed in epithelial tissues. Because mdr1a(-/-) mice tend to develop spontaneous colitis in bacteria-dependent manner, Pgp is believed to have a role in protection of the intestinal epithelium from luminal bacteria. Here we demonstrate that levels of Pgp in the small intestine of newborn rodents dramatically increase during breastfeeding, but not during formula feeding (FF). In rats and mice, levels of intestinal Pgp peak on days 3-7 and 1-5 of breastfeeding, respectively. The mdr1a(-/-) neonatal mice subjected to FF, hypoxia, and hypothermia have significantly higher incidence and pathology, as well as significantly earlier onset of necrotizing enterocolitis (NEC) than congenic wild type mice. Breast-fed mdr1a(-/-) neonatal mice are also more susceptible to intestinal damage caused by the opportunistic pathogen Cronobacter sakazakii that has been associated with hospital outbreaks of NEC. Breast milk, but not formula, induces Pgp expression in enterocyte cell lines in a dose- and time-dependent manner. High levels of ectopically expressed Pgp protect epithelial cells in vitro from apoptosis induced by C. sakazakii. Taken together, these results show that breast milk-induced expression of Pgp may have a role in the protection of the neonatal intestinal epithelium from injury associated with nascent bacterial colonization.

In pediatric kidney transplantation, the effect of inadequate nephron dosing on graft survival remains undetermined. The aim of this study was to assess the use of D/R BSA, as a reliable indicator of adequate nephron dosing, and eventually a tool to optimize pediatric graft allocation. Following Institutional Review Board approval, we reviewed deceased donor pediatric kidney transplantation (N = 156). We divided patients into three groups, based on D/R BSA: A < or =0.8; B 0.81-1.19; C > or =1.2. Five-yr graft survival rates in the groups were: A 82.0%; B 94.9%; C 97.1% (p = 0.01). Group C had the lowest rate of acute rejection, suggesting a protective effect of increased D/R BSA (group A = 35.7%, group B = 38.9%, group C = 18.8%; p = 0.029). The logistic regression analysis showed that decreased D/R BSA ratio is a risk factor for loss of graft function, at one and five yr [i.e., group A OR 6 (95% CI 1.14-39.30, p = 0.015) and OR 4.49 (95% CI 1.46-13.79, p = 0.009), respectively]. We conclude that for pediatric recipients, D/R BSA is a valuable adjunct when determining long-term graft survival. Its utility may avoid an alloimmune-independent risk factor, increasing the long-term protective value of a good matching policy.

BACKGROUND: Choledochal cyst (CDC) is a rare biliary disorder. Surgical treatment consists of CDC excision and biliary-enteric reconstruction. Recently, some institutions have reported successful CDC excision by using minimally invasive techniques. In this study, we report our experience with the laparoscopic management of CDC, with a focus on key operative maneuvers that enhance the likelihood of successful excision. METHODS: Following institutional review board approval, we performed a retrospective review of patients who underwent the laparoscopic excision of CDC and Roux-en-Y hepaticojejunostomy. Between October 2003 and November 2007, we performed laparoscopic CDC excision in 9 patients (8 female and 1 male). Median age was 4 years (range, 8 months to 16 years). There were 7 type I and 2 type IV cysts, according to Todani's classification. Average cyst size was 4.4 cm (range, 1.3-8.5). The procedures were performed by utilizing four or five trochars. RESULTS: Six of 9 children presented with preoperative pancreatitis, 1 with abdominal pain, 1 with jaundice, and 1 was found incidentally. Three patients required the conversion to laparotomy due to dense adhesions, secondary to pancreatitis. Six patients underwent successful laparoscopic procedures, 5 had complete cyst excisions, and 1 underwent a proximal excision with distal mucosectomy. Of the 3 patients who required conversion, 2 underwent complete excisions; the other underwent a proximal excision, distal mucosectomy. There were no intraoperative complications. One patient had a postoperative bile leak that required an open hepaticojejunostomy revision. Eight patients had an uneventful recovery. Oral feedings were resumed within an average of 3.4 days (range, 2-9). Average time to discharge was 6.1 days (range, 5-12). Average follow-up time was 18 months (range, 4-48). No further laboratory abnormalities were detected in any of the patients. CONCLUSIONS: Laparoscopic resection of CDC and Roux-en-Y hepaticojejunostomy in children is an excellent treatment option. Preoperative pancreatitis may cause increased technical difficulty, necessitating a conversion. Proximal excision with distal mucosectomy

Severe caustic burns to the esophagus may necessitate esophagectomy with replacement, if stictures form which are not amenable to dilation. Traditionally, the operation is performed via open transabdominal and/or thoracic approaches. Here we describe our minimally invasive approach, combining laparoscopy and thoracoscopy for esophagectomy, stomach tubularization and a cervical esophagogastrotomy. We successfully performed the procedure in a 4-year-old boy. There were no intraoperative complications, and his initial esophagram showed good patency with no leaks. However, one week postoperatively he was noted to have a retained foreign body and a minor anastomotic leak, which was most likely caused by the foreign body. He underwent a neck re-exploration,removal of the foreign body, and repair of the anastomotic leak. His subsequent hospital course was uneventful. He tolerated feedings and was discharged home on an unrestricted diet. The minimally invasive approach to esophagectomy and esophageal replacement is feasible and is an excellent option in select patients.

Necrotizing enterocolitis (NEC) is the most common life-threatening gastrointestinal disease encountered in the premature infant. Although the inciting events leading to NEC remain elusive, various risk factors, including prematurity, hypoxemia, formula feeding, and intestinal ischemia, have been implicated in the pathogenesis of NEC. Data from our laboratory and others suggest that NEC evolves from disruption of the intestinal epithelial barrier, as a result of a combination of local and systemic insults. We postulate that nitric oxide (NO), an important second messenger and inflammatory mediator, plays a key role in intestinal barrier failure seen in NEC. Nitric oxide and its reactive nitrogen derivative, peroxynitrite, may affect gut barrier permeability by inducing enterocyte apoptosis (programmed cell death) and necrosis, or by altering tight junctions or gap junctions that normally play a key role in maintaining epithelial monolayer integrity. Intrinsic mechanisms that serve to restore monolayer integrity following epithelial injury include enterocyte proliferation, epithelial restitution via enterocyte migration, and re-establishment of cell contacts. This review focuses on the biology of NO and the mechanisms by which it promotes epithelial injury while concurrently disrupting the intrinsic repair mechanisms.

Necrotizing enterocolitis (NEC) is a devastating illness that predominantly affects premature neonates. The mortality associated with this disease has changed very little during the last two decades. Neonates with NEC fall into two categories: those who respond to medical management alone and those who require surgical treatment. The disease distribution may be focal, multifocal, or panintestinal. Surgical treatment should therefore be based on disease presentation. Recent studies have added significant insight into our understanding of the pathogenesis of NEC. Several groups have shown that upregulation of nitric oxide plays an integral role in the development of epithelial injury in NEC. As a result, some treatment strategies have been aimed at abrogating the toxic effects of nitric oxide. In addition, several investigators have reported the cytoprotective effect of epidermal growth factor, which is found in high levels in breast milk, on the intestinal epithelium. Thus, fortification of infant formula with specific growth factors could soon become a preferred strategy to accelerate intestinal maturation in the premature neonate to prevent the development of NEC. One of the most devastating complications of NEC is the development of short bowel syndrome (SBS). The current treatment of SBS involves intestinal lengthening procedures or bowel transplantation. A novel emerging method for treating SBS involves the use of tissue-engineered intestine. In laboratory animals, tissue-engineered small intestine has been shown to be successful in treating intestinal failure. This article examines recent data regarding surgical treatment options for NEC as well as emerging treatment modalities.

INTRODUCTION: The use of minimally invasive surgery (MIS) in the neonatal population is increasing. Thoracoscopic intervention for congenital diaphragmatic hernia (CDH) is no exception. In this report, we describe our initial experience with thoracoscopic repair of left-sided diaphragmatic defects in neonates. MATERIALS AND METHODS: We performed retrospective chart reviews on all neonates who underwent thoracoscopic repair of CDH between November 2004 and January 2008. Neonates that underwent thoracoscopic repair were physiologically stable with resolved pulmonary hypertension and minimal to moderate ventilatory support. They had no associated cardiac anomalies. RESULTS: We identified 15 neonates with CDH who underwent thoracoscopic repair during the study period. Ten neonates underwent primary repair of the diaphragmatic defect. Five neonates with large defects required closure with a synthetic patch, which was placed thoracoscopically. The average operating room time was 134 minutes. There were no instances of intraoperative respiratory or cardiac instability. Three patients had a recurrence. One recurrence was seen after thoracoscopic patch repair. Two recurrences occurred following primary repair of left diaphragmatic hernias. There were no deaths. Follow-up has been 4-40 months. CONCLUSIONS: Neonatal MIS for CDH should be limited to stable patients. The ideal candidate is the newborn without associated anomalies, not requiring extracorporeal membrane oxygenation, on minimal ventilatory support, and without evidence of pulmonary hypertension. It is technically possible to perform thoracoscopic repair with a patch.

Current evidence suggests that the majority of injured children are not treated in a pediatric trauma center. This review failed to provide a definitive answer to the question of whether injured children treated at children's hospitals or adult hospitals with a dedicated pediatric unit have better outcomes than those treated at adult hospitals. However, it identified areas that have been addressed, and more importantly, uncovered others that are largely unanswered. In lieu of a prospective randomized trial, the next best way to address these unsolved issues would be a prospective collection of data with careful attention to assessing injury severity, physiologic response to the injury, associated injuries and comorbidities, along with resuscitation techniques, hospital resources, and manpower training.

Injury to the solid abdominal organs-liver, spleen, kidney, and pancreas-is one of the most common injury patterns in pediatric blunt trauma. Pediatric trauma centers are becoming increasingly successful in managing these injuries without operative intervention. Well-validated guidelines have been established for liver and spleen injury management, and operative intervention is reserved for patients who show evidence of active bleeding after resuscitation. No such guidelines yet exist for the management of traumatic injury of the kidney or pancreas. Exploratory laparotomy remains the treatment of choice in patients suffering hemodynamic collapse, but interventional radiologic or endoscopic procedures are increasingly used to manage all but the most devastating solid organ injuries.

OBJECTIVE: The objective of this study was to examine factors associated with pediatric nurse practitioners (PNPs) reporting to work in the event of a disaster. METHODS: An anonymous national survey of PNPs was conducted. Several domains were explored, including demographics, personal preparedness plans, disaster training, prior disaster experience, and likelihood of responding in the event of a disaster. A logistic regression analysis was conducted to determine which factors were associated with the respondent's likelihood of responding in the event of a disaster. RESULTS: Factors associated with increased likelihood of responding included gender (being a male PNP), military experience, and disaster training. The most significant factor associated with an increased likelihood of responding to work during a disaster was having a specified role in the workplace disaster plan. PNPs with a specified role were three times more likely to respond than were those without a specified role. CONCLUSIONS: PNPs are health care workers with advanced skill sets. This untapped resource is available to provide care for a vulnerable population: our children. Disaster planners should explore the possibility of utilizing these highly skilled health care workers in their disaster plans.

BACKGROUND: Necrotizing enterocolitis (NEC) is the most common gastrointestinal emergency in premature neonates. The pathogenesis of NEC is characterized by an intestinal epithelial injury caused by perinatal insults, leading to the activation of the mucosal innate immune system and exacerbation of the epithelial barrier damage. Cytokines play an important role in mucosal immunity. Interleukin-10 (IL-10) is an anti-inflammatory cytokine that has been shown to play a role in epithelial integrity and modulation of the mucosal immune system. We hypothesized that IL-10 may protect against the development of experimental NEC by blunting the inflammatory response in the intestine. METHODS: Wild-type and IL-10 -/- mice underwent a NEC-inducing regimen of formula feeding in combination with hypoxia and hypothermia (FF+HH). Integrity of the gut barrier was assessed through measurement of epithelial apoptosis, tight junction disruption, and inducible nitric oxide synthase. A total of 5 µg of exogenous IL-10 was administered intraperitoneally to IL-10-/-mouse pups before the initiation of FF+HH to test dependence of gene knockout phenotype on IL-10. RESULTS: IL-10 -/- FF+HH showed more severe morphologic and histologic changes compared with controls as evidenced by increased epithelial apoptosis, decreased junctional adhesion molecule-1 localization, and increased intestinal inducible nitric oxide synthase expression. Administration of exogenous IL-10 alleviated the mucosal injury. CONCLUSIONS: We conclude that IL-10 plays a protective role in the pathogenesis of NEC by attenuating the degree of intestinal inflammation.

INTRODUCTION: Due to recent disasters, disaster planners increasingly are focusing on healthcare worker preparedness and response in the event of a disaster. In this study, factors associated with pediatric healthcare workers' willingness to respond are identified. HYPOTHESIS: It was hypothesized that personal factors may affect a pediatric healthcare worker's willingness to respond to work in the event of a disaster. METHODS: Employees of a tertiary, pediatric care hospital in Los Angeles were asked to complete a brief, 24-question online survey to determine their willingness to respond in the event of a disaster. Information on demographics, employment, disaster-related training, personal preparedness, and necessary resources was collected. A logistic regression model was performed to derive adjusted odds ratios (OR) and their corresponding 95% confidence intervals (95% CI). RESULTS: Eight hundred seventy-seven pediatric healthcare employees completed the survey (22% response rate). Almost 50% (n = 318) expressed willingness to respond in the event of a disaster. Men were more likely to be willing to respond to a disaster than were women (OR = 2.4; 95%CI = 1.6-3.6), and single/divorced/widowed employees were more willing to respond than married or partnered employees (OR = 1.5; 95%CI = 1.1-2.1). An inverse relationship was observed between number of dependents and willingness to respond (OR = 0.45; 95%CI = 0.25-0.80, ≥3 dependents compared to 0). An inverse dose response relationship between commuting distance and number of necessary resources (ptrend = 0.0485 and 0.0001, respectively) was observed. There was no association between previous disaster experience, disaster training, or personal preparedness and willingness to respond. CONCLUSIONS: Number of dependents and resources were major factors in willingness to respond. Healthcare facilities must clearly communicate their disaster plans as well as any provisions they may make for their employees' families in order to improve willingness among hospital employees.

OBJECTIVE: To describe the level of preparedness in performing medical procedures of medical students at one allopathic medical school and to determine the level of willingness to perform these procedures in the event of a disaster. DESIGN: Cross-sectional survey. SETTING: US allopathic medical school associated with a county hospital. PARTICIPANTS: All third- and fourth-year medical students (344) in the 2007-2008 academic year were invited to participate. One hundred ninety-five students participated in this study (response rate = 57.6 percent). MAIN OUTCOME MEASURES: Information on demographic characteristics, personal disaster experience, personal disaster preparedness, and overall preparedness level and willingness to perform various medical procedures was collected. Multiple regression analysis was used to identify the factors predicting procedural willingness during a disaster. RESULTS: Demographics and personal disaster preparedness were not statistically significant between third-year medical students (M3) and fourth-year medical students (M4). Although procedural preparedness was significantly higher in M4 than M3, willingness to perform these procedures in a disaster was not different. Fourth-year students, first receivers (students' anticipated field is in emergency medicine or surgery), not having had a personal disaster experience, and increased procedural preparedness independently impact procedural willingness in a disaster However, when controlled for the covariate effects in the regression model, only first receivers, no past personal disaster experience, and increased procedural preparedness predicted willingness to perform medical procedures during a disaster. CONCLUSIONS: Third- and fourth-year students possess skills that may prove useful in a disaster response. Further investigations are necessary to determine how medical students may be utilized during these events.

PURPOSE: Laparoscopic inversion herniotomy (LIH) is a method of inguinal hernia repair for female patients. In this article, we report our technique and outcomes for this procedure. We propose that LIH is a valid alternative to conventional open herniorraphy. METHODS: Following institutional review board approval, we reviewed the charts of patients who underwent LIH or open inguinal hernia repair (OIH) from 2004 to 2007. LIH was performed with three instrument sites and no groin incision. The diagnosis, operative time, and complications were reviewed. Follow-up ranged from 5 months to 4 years. RESULTS: We performed 79 LIH repairs (15 bilateral, 23 left, and 26 right) in 63 female children. We also performed 76 contemporaneous OIH repairs in girls. The age range was 1 month to 18 years (median, 3.8 years). Operative times for both the unilateral and bilateral LIH repairs were significantly shorter than those for OIH (P = 0.001). There were 2 recurrences after laparoscopic inguinal hernia repair, both within 5 months following repair early in our experience, compared to no hernia recurrences with OIH. The first recurrence was repaired conventionally via an open technique. The second case was repaired laparoscopically. CONCLUSIONS: LIH is an effective method for the repair of pediatric indirect inguinal hernia in female patients. The procedure allows the evaluation of the asymptomatic contralateral side without the necessity of a second long inguinal incision.

BACKGROUND: An academic surgeon's workweek is divided among patient care, administrative duties, education, and research. The time available for research activities may change as a surgeon's career evolves. We sought to determine involvement of academic surgeons in research and to assess how this research endeavor was affected by demographic and workplace characteristics. METHODS: We constructed a survey to explore the following 4 domains: demographics, time allotment, research activities, and effects of stressors. We distributed the survey to members of the Society of University Surgeons. In addition to performing descriptive statistics, we defined an active researcher as someone with a funding source who devoted 15% or more work hours to research. Using this definition, we performed statistical analyses to assess the significance of independent variables on research. Stress factors were evaluated on a Likert scale with responses ranging from 1 (not at all) to 5 (extremely). RESULTS: We received 314 completed surveys (response rate 23%). Of the respondents, 274 (87%) stated that they were involved in some kind of research activity; however, only 143 (46%) were active researchers. Using univariate logistic regression analysis, younger respondents and surgeons who practiced for more than 10 years were more likely to be active researchers (odds ratio [OR]: 1.93, confidence interval [CI]: 1.51-2.46 and OR: 2.06, CI: 1.64-2.59, respectively). Males were less likely than females to be active researchers (OR: 0.32, CI: 016-0.67); however, by multivariate analysis, we found that the "years in practice" of an active researcher was the most significant predictor of research activity, whereas age and sex were not. In regard to stress, most respondents reported scores of 1-3 for all 7 stressors, which is consistent with minimal to moderate stress. CONCLUSION: Academic surgeons are involved actively in research; however, this involvement decreases as other professional responsibilities increase. To optimize the surgical research environment, departments should invest time and resources in young investigators to prevent them from decreasing their research activities.

We have previously reported that fibroblast growth factor 10 (FGF10) is crucial for the survival and proliferation of progenitor cells during embryonic gastrointestinal development. We sought to characterize the potential role of FGF10 signaling in the adaptive response following small bowel resection. Adult wild-type and Fgf10(LacZ) mice underwent 50% small bowel resection (SBR) or sham operation. Tissues were harvested 24 or 48 hr after surgery for histology, immunohistochemistry, and in situ hybridization. After SBR, Fgf10 expression was demonstrated in the epithelium at the base of the crypts. Moreover, there was a statistically significant increase in proliferating cells and goblet cells after SBR. In vitro studies using rat intestinal epithelial crypt (IEC-6) cells exposed to medium with or without recombinant FGF10 showed increased proliferation and phosphorylation of Raf and AKT with the addition of FGF10. Our results suggest that FGF10 may play a therapeutic role in diseases involving intestinal failure.
