Clinical Utility of Laser Speckle Contrast Imaging and Real-Time Quantification of Bowel Perfusion in Minimally Invasive Left-Sided Colorectal Resections.

BACKGROUND: Left-sided colorectal surgery demonstrates high anastomotic leak rates, with tissue ischemia thought to influence outcomes. Indocyanine green is commonly used for perfusion assessment, but evidence remains mixed for whether it reduces colorectal anastomotic leaks. Laser speckle contrast imaging provides dye-free perfusion assessment in real-time through perfusion heat maps and quantification. OBJECTIVE: This study investigates the efficacy of advanced visualization (indocyanine green versus laser speckle contrast imaging), perfusion assessment, and utility of laser speckle perfusion quantification in determining ischemic margins. DESIGN: Prospective intervention group using advanced visualization with case-matched, retrospective control group. SETTINGS: Single academic medical center. PATIENTS: Forty adult patients undergoing elective, minimally invasive, left-sided colorectal surgery. INTERVENTIONS: Intraoperative perfusion assessment using white light imaging and advanced visualization at 3 time points: T1-proximal colon after devascularization, before transection, T2-proximal/distal colon before anastomosis, and T3-completed anastomosis. MAIN OUTCOME MEASURES: Intraoperative indication of ischemic line of demarcation before resection under each visualization method, surgical decision change using advanced visualization, post hoc laser speckle perfusion quantification of colorectal tissue, and 30-day postoperative outcomes. RESULTS: Advanced visualization changed surgical decision-making in 17.5% of cases. For cases in which surgeons changed a decision, the average discordance between the line of demarcation in white light imaging and advanced visualization was 3.7 cm, compared to 0.41 cm ( p = 0.01) for cases without decision changes. There was no statistical difference between the line of ischemic demarcation using laser speckle versus indocyanine green ( p = 0.16). Laser speckle quantified lower perfusion values for tissues beyond the line of ischemic demarcation while suggesting an additional 1 cm of perfused tissue beyond this line. One (2.5%) anastomotic leak occurred in the intervention group. LIMITATIONS: This study was not powered to detect differences in anastomotic leak rates. CONCLUSIONS: Advanced visualization using laser speckle and indocyanine green provides valuable perfusion information that impacts surgical decision-making in minimally invasive left-sided colorectal surgeries.

UTILIDAD CLNICA DE LAS IMGENES DE CONTRASTE MOTEADO CON LSER Y LA CUANTIFICACIN EN TIEMPO REAL DE LA PERFUSIN INTESTINAL EN RESECCIONES COLORRECTALES DEL LADO IZQUIERDO MNIMAMENTE INVASIVAS: ANTECEDENTES:La cirugía colorrectal del lado izquierdo demuestra altas tasas de fuga anastomótica, y se cree que la isquemia tisular influye en los resultados. El verde de indocianina se utiliza habitualmente para evaluar la perfusión, pero la evidencia sobre si reduce las fugas anastomóticas colorrectales sigue siendo contradictoria. Las imágenes de contraste moteado con láser proporcionan una evaluación de la perfusión sin colorantes en tiempo real a través de mapas de calor de perfusión y cuantificación.OBJETIVO:Este estudio investiga la eficacia de la evaluación de la perfusión mediante visualización avanzada (verde de indocianina versus imágenes de contraste moteado con láser) y la utilidad de la cuantificación de la perfusión con moteado láser para determinar los márgenes isquémicos.DISEÑO:Grupo de intervención prospectivo que utiliza visualización avanzada con un grupo de control retrospectivo de casos emparejados.LUGARES:Centro médico académico único.PACIENTES:Cuarenta pacientes adultos sometidos a cirugía colorrectal electiva, mínimamente invasiva, del lado izquierdo.INTERVENCIONES:Evaluación de la perfusión intraoperatoria mediante imágenes con luz blanca y visualización avanzada en tres puntos temporales: T1-colon proximal después de la devascularización, antes de la transección; T2-colon proximal/distal antes de la anastomosis; y T3-anastomosis completa.PRINCIPALES MEDIDAS DE VALORACIÓN:Indicación intraoperatoria de la línea de demarcación isquémica antes de la resección bajo cada método de visualización, cambio de decisión quirúrgica mediante visualización avanzada, cuantificación post-hoc de la perfusión con láser moteado del tejido colorrectal y resultados posoperatorios a los 30 días.RESULTADOS:La visualización avanzada cambió la toma de decisiones quirúrgicas en el 17,5% de los casos. Para los casos en los que los cirujanos cambiaron una decisión, la discordancia promedio entre la línea de demarcación en las imágenes con luz blanca y la visualización avanzada fue de 3,7 cm, en comparación con 0,41 cm (p = 0,01) para los casos sin cambios de decisión. No hubo diferencias estadísticas entre la línea de demarcación isquémica utilizando láser moteado versus verde de indocianina (p = 0,16). El moteado con láser cuantificó valores de perfusión más bajos para los tejidos más allá de la línea de demarcación isquémica y al mismo tiempo sugirió 1 cm adicional de tejido perfundido más allá de esta línea. Se produjo una fuga anastomótica (2,5%) en el grupo de intervención.LIMITACIONES:Este estudio no tuvo el poder estadístico suficiente para detectar diferencias en las tasas de fuga anastomótica.CONCLUSIONES:La visualización avanzada utilizando moteado láser y verde de indocianina proporciona información valiosa sobre la perfusión que impacta la toma de decisiones quirúrgicas en cirugías colorrectales mínimamente invasivas del lado izquierdo.

Outcomes of children with constipation and autism spectrum disorder treated with antegrade continence enemas.

BACKGROUND: Treatment of functional constipation (FC) in children with autism spectrum disorder (ASD) is challenging due to sensory and behavioral issues. We aimed to understand whether antegrade continence enemas (ACEs) are successful in the treatment of FC in children with ASD. METHODS: A single-institution retrospective review was performed in children diagnosed with ASD and FC who underwent appendicostomy or cecostomy placement from 2007 to 2019. Descriptive statistics regarding soiling and complications were calculated. RESULTS: There were 33 patients included, with a median age of 9.7 years at the time of ACE initiation. The average intelligence quotient was 63.6 (SD = 18.0, n = 12), the average behavioral adaptive score was 59.9 (SD = 11.1, n = 13), and the average total Child Behavioral Checklist score was 72.5 (SD = 7.1, n = 10). Soiling rates were significantly lower following ACE initiation (42.3% vs. 14.8%, p = 0.04). Behavioral issues only prevented 1 patient (3.0%) from proper ACE use. Eleven patients (36.6%) were able to transition to laxatives. There were significant improvements in patient-reported outcomes measures and quality of life. CONCLUSION: Placement of an appendicostomy or cecostomy for management of FC in children with severe ASD was successful in treating constipation and improving quality of life.

Impact of Neurodevelopmental Disorders on Bowel Management Outcomes in Children with Functional Constipation.

OBJECTIVES: Patients experiencing functional constipation (FC) can participate in structured bowel management programs (BMPs) to manage constipation or fecal incontinence when standard management fails. We sought to evaluate the efficacy of BMPs for children with FC with and without neurodevelopmental disorders. METHODS: We performed a retrospective review of children with FC who participated in our BMP from 2014 to 2021. Stool/urinary continence, bowel regimen, surgical history, parent-reported outcomes measures (PROMs: Cleveland Clinic Constipation Score, Baylor Continence Scale, Vancouver Symptom Score for Dysfunctional Elimination), and Pediatric Quality of Life Inventory (PedsQL) were assessed pre- and at least 9 months post-BMP. RESULTS: The cohort included 156 patients with a median age of 9 years and follow-up of 627 days (IQR: 389-808 days). Two sub-cohorts included patients with FC only (69%) and FC plus a neurodevelopmental disorder (31%): 59% attention-deficit/hyperactivity disorder, 33% autism spectrum disorder, and 8% obsessive-compulsive disorder. Both groups had significantly improved follow-up bowel movement frequency and continence (39%-90% neurodevelopmental, 44%-82% FC only, P < 0.001) and urinary continence (65%-90% neurodevelopmental, 69%-91% FC only, P < 0.02). There was a significant improvement in most of the PROMs at follow-up. Both groups experienced a clinically meaningful improvement in overall PedsQL scores (pre- and postBMP difference of >4.5). CONCLUSIONS: Patients with FC with and without a neurodevelopmental disorder had significant improvement in stool and urinary continence after undergoing a BMP. Further studies are needed to see if this improvement is durable over a longer period of time in this challenging cohort.

Disparate Use of Chemoradiation in Elderly Patients With Localized Anal Cancer.

BACKGROUND: The incidence of squamous cell carcinoma of the anus (SCCA) is increasing, particularly among the elderly (age ≥65 years). We sought to compare patterns of care for the treatment of SCCA in elderly versus nonelderly patients. METHODS: Data for patients with stages I-III SCCA diagnosed from 2004 through 2015 were obtained from the National Cancer Database. Patients were categorized as having received standard-of-care (SOC) chemoradiation (CRT) with multiagent chemotherapy, non-SOC therapy, palliative therapy, or no treatment. Differences in treatment groups were tested using the chi-square test. We used logistic regression to identify predictors of SOC CRT and multiagent versus single-agent chemotherapy in patients receiving CRT. Propensity score matching was used to compare overall survival (OS) in elderly patients receiving multiagent versus single-agent chemotherapy for those receiving CRT. RESULTS: We identified 9,156 elderly and 17,640 nonelderly patients. A lower proportion of elderly versus nonelderly patients (54.5% vs 65.0%; P<.0001) received SOC CRT than other treatments or no treatment. In multivariate analysis, elderly patients were 38% less likely than nonelderly patients to receive SOC CRT (odds ratio, 0.62; 95% CI, 0.58-0.65; P<.0001). A higher proportion of the elderly were treated with single-agent versus multiagent chemotherapy (16.9% vs 11.8%; P<.0001), which resulted in a >1.5-fold increase in the likelihood of elderly patients receiving single-agent chemotherapy (odds ratio, 1.52; 95% CI, 1.39-1.66) in multivariate analysis. After propensity score matching, 3-year OS was higher in elderly patients who received CRT with multiagent versus single-agent chemotherapy (77.1% vs 67.5%; hazard ratio, 0.78; 95% CI, 0.68-0.89; P=.0002). CONCLUSIONS: In this comprehensive study of patients with stages I-III SCCA, elderly patients were less likely than nonelderly patients to receive SOC CRT. The low proportion of elderly patients receiving SOC CRT with multiagent chemotherapy for localized anal cancer suggests that the optimal treatment approach for this vulnerable population remains undefined.

Evaluation and Management of Persistent Problems After Surgery for Hirschsprung Disease in a Child.

PURPOSE OF REVIEW: Ideally, after operative intervention, a child born with Hirschsprung disease (HD) should thrive, achieve fecal continence, and avoid recurrent episodes of abdominal distention and enterocolitis. However, a significant number of patients continue to struggle following their pull-through procedure. The purpose of this review is to present an organized and practical approach to the evaluation and management of the symptomatic patient post pull-through operation for HD. RECENT FINDINGS: Children diagnosed with HD who are not doing well after their initial operation can be categorized in three distinct groups: (1) those that have fecal incontinence, (2) those with obstructive symptoms, and (3) those with recurrent episodes of enterocolitis. It is important to have a systematic diagnostic approach for these patients based on a comprehensive protocol. All three of these patient groups can be treated with a combination of either medical management, reoperation when a specific anatomic or pathologic etiology is identified, or botulinum toxin for non-relaxing sphincters contributing to the obstructive symptoms or recurrent enterocolitis. For patients not doing well after their initial pull-through, a systematic workup should be employed to determine the etiology. Once identified, a multidisciplinary and organized approach to management of the symptomatic patients can alleviate most post pull-through symptoms.

Hirschsprung Disease: The Rise of Structured Transition and Long-term Care.

Hirschsprung disease, like most surgically correctable congenital anomalies, is now survivable well into adulthood. Patients are, therefore, presenting later in life with problems that were previously infrequently encountered by colorectal surgeons or gastroenterologists. The goals of our review are to describe the current state of care transition for this patient population, identify the specific needs for these patients, and propose guidelines which could inform a future model of transition from the pediatric to adult setting. This is a review of the current state of care transition and long-term outcomes for patients with Hirschsprung disease. Although these patients report a generally good quality of life, the majority suffer from some degree of lifelong gastrointestinal complication, regardless of the type of operative repair. A more formalized transition of care will provide a guide for pediatric surgeons and patients, alleviate colorectal surgeon and gastroenterologist concerns, and provide better long-term care for these patients.

Transcending Dimensions: a Comparative Analysis of Cloaca Imaging in Advancing the Surgeon's Understanding of Complex Anatomy.

Surgeons have a steep learning capacity to understand 2-D images provided by conventional cloacagrams. Imaging advances now allow for 3-D reconstruction and 3-D models; but no evaluation of the value of these techniques exists in the literature. Therefore, we sought to determine if advances in 3-D imaging would benefit surgeons, lead to accelerated learning, and improve understanding for operative planning of a cloaca reconstruction. Questionnaires were used to assess the understanding of 2-D and 3-D images by pediatric surgical faculty and trainees. For the same case of a cloacal malformation, a 2D contrast study cloacagram, a 3D model rotatable CT scan reconstruction, a software enhanced 3D video animation (which allowed the observer to manipulate the structure in any orientation), and a printed physical 3D cloaca model that could be held in the observer's hand were employed. Logistic mixed effect models assessed whether the proportion of questions about the case that were answered correctly differed by imaging modality, and whether the proportion answered correctly differed between trainee and attending surgeons for any particular modality. Twenty-nine pediatric surgery trainees (27 pediatric general surgery and 2 pediatric urology surgery trainees) and 30 pediatric surgery and urology faculty participated. For trainees, the percentage of questions answered correctly was: 2-D 10.5%, 3-D PACS 46.7%, 3-D Enhanced 67.1%, and 3-D Printed 73.8%. For faculty, the total percentage of questions answered correctly was: 2-D 22.2%, 3-D PACS 54.8%, 3D Enhanced 66.2%, and 3-D printed 74.0%. The differences in rates of correctness across all four modalities were significant in both fellows and attendings (p < 0.001), with performance being lowest for the 2-D modality, and with increasing percentage of correct answers with each subsequent modality. The difference between trainees and attendings in correctness rate was significant only for the 2-D modality, with attendings answering correctly more often. The 2-D cloacagram, as the least complex model, was the most difficult to interpret. The more complex the modality, the more correct were the responses obtained from both groups. Trainees and attendings had similar levels of correct answers and understanding of the cloacagram for the more advanced modalities. Mental visualization skills of anatomy and complex 3-D spatial arrangements traditionally have taken years of experience to master. Now with novel surgical education resources of a 3-D cloacagram, a more quickly advancing skill is possible.

Challenges in Transition of Care for Patients With Anorectal Malformations: A Systematic Review and Recommendations for Comprehensive Care.

BACKGROUND: Anorectal malformations are one of the most common congenital intestinal anomalies affecting newborns. Despite advances in neonatal care and surgical techniques, many patients with a history of anorectal malformations are affected by long-term challenges involving bowel and bladder dysfunction, sexual dysfunction, and psychosocial issues. These outcomes or challenges are additionally exacerbated by the lack of a structured transition of care from the pediatric to the adult setting. OBJECTIVE: The purpose of this review is to describe the long-term outcomes affecting patients with a history of anorectal malformations, review the current literature on transition of care, and make recommendations for developing a standardized program for transitioning care for a select group of colorectal surgical patients. DATA SOURCES: An extensive PubMed review of articles in English was performed to evaluate current best practices for chronic illnesses of childhood with residual symptoms or need for medical care into adulthood. STUDY SELECTION: Meta-Analysis of Observational Studies in Epidemiology group guidelines were followed. MAIN OUTCOME MEASURES: The primary outcome for this review was the existence of transitional services for patients with a history of anorectal malformations and evaluations of long-term outcomes affecting patients with a history of anorectal malformations. RESULTS: Systematic review revealed improved results in transition programs as determined by patient follow-up, medication adherence, and patient and family satisfaction through the use of multidisciplinary teams. Standardized tools for assessing all aspects of patient outcomes and quality of life are essential for describing the burden of disease affecting a transitioning population. LIMITATIONS: This is a retrospective review of the current status of a complex and rapidly evolving field of delivery of care. More work is needed to apply uniform approaches and assess the impact, patient outcomes, and quality of life. CONCLUSIONS: Patients who undergo childhood procedures for anorectal malformations often experience chronic symptoms related to the bowel, bladder, and reproductive organs, as well as psychosocial disturbances. This population will benefit from appropriate engagement in transitional care plans. See Video Abstract at http://links.lww.com/DCR/A543.

Unusual Management of Fecal Impaction in an Adult With Functional Constipation: A Urological Adventure.

A 27-year-old male with a history of functional constipation presented for ileostomy closure. He had a 12-cm impacted rectal stool ball precluding safe ileostomy takedown. He underwent multiple unsuccessful attempts at removal, including colotomy, antegrade and retrograde enemas, and manual disimpaction. The urological team suggested a novel approach using lithotripsy. A 26-French rigid nephroscope and the Olympus ShockPulse SE ultrasonic lithotripter were utilized transanally to break up the impacted stool ball. The patient was discharged the same day without complication. Ultrasonic lithotripsy is an unusual yet effective modality for prolonged fecal impaction. By employing a unique, multidisciplinary technique, operative morbidity was avoided.

Pregnancy in Medical Training: A Survey of Physician Moms on Their Experiences During Residency and Fellowship.

OBJECTIVE: Resident physicians undergo physically and emotionally rigorous training; this is particularly difficult for the pregnant resident and affects their unborn child. This study aims to elucidate pregnant residents' perspectives regarding their prenatal and postnatal experiences, across all specialties, with a focus on pregnancy complications, postpartum health, and policy execution. DESIGN: This is a nationwide cross-sectional survey study developed to characterize resident and fellow perceptions about work schedules while pregnant, perceived discrimination, complications during pregnancy, lactation and lactation support, marital distress, parental leave policy, and overall satisfaction with the parental leave period. Descriptive statistics were used to characterize survey responses. SETTING/PARTICIPANTS: The experiences of physician mothers in online Facebook support groups: Physician Mom Group, Surgeon Mom Group, and Dr Mothers Interested in Lactation Knowledge, were queried by an electronic survey distributed using Qualtrics XM. Physicians who had children during their U.S. residency training were eligible to participate and 1,690 physician mothers from all specialties completed the survey. RESULTS: One thousand six hundred and ninety responses from members of the Facebook support groups were analyzed. Most surveyed physicians (1353/1519, 89.1%) were required to work until delivery and 63.6% (993/1561) of women took in-house calls during the last month of pregnancy. Half (820/1560, 52.6%) thought that the physical demands of their jobs compromised their own health and safety, or that of their child, and 1259 complications were reported among 1690 respondents, an average of three complications for every four respondents. Twenty-nine percent (442/1519, 29.1%) of physician mothers suffered from postpartum depression. Ninety-two percent (1479/1602, 92.3%) of respondents breastfed, but only one-third (483/1456, 33.2%) breastfed for more than 12 months and 52.7% (769/1458) would have liked to breastfeed longer. Marital distress was reported by nearly half (756/1650, 45.8%) of respondents during pregnancy and/or the first year of their child's life due to parental leave policies. The majority (957/1688, 56.7%) did not have a parental leave policy at their institution. Nearly two-thirds (946/1518, 62.3%) of respondents took 6 or fewer weeks off, and 79.7% (1211/1520) felt their duration of time off was inadequate. Nearly 30% (457/1593, 28.7%) stated they would recommend against a female medical student going into their field of medicine based upon their own experiences during pregnancy. CONCLUSIONS: Many mothers experienced discrimination from colleagues and worked until delivery despite concerns about the health and safety of themselves or their unborn children, and many reported experiencing a pregnancy-related complication. Most did not have a parental leave policy, which likely contributed to the disproportionately higher rates of postpartum depression among physician mothers compared to the general public. Residency training parental leave policies should be more accommodating to improve mental health, career satisfaction, and retention of the next generation of physician mothers.

Development of a Standardized Process for Transition to Adult Care in a Pediatric Colorectal Surgery Clinic.

BACKGROUND: As pediatric patients with colorectal diseases grow, it is important to address transition to adult practice. We aim to describe our center's transition process and early outcomes. METHODS: We developed a standardized process for transition to adult practice. An annual survey is given to parents and caregivers starting at age 12 that assesses knowledge of disease, independence with healthcare tasks, and confidence and interest regarding transition. After multidisciplinary review, those eligible are recommended for transition. Those not referred are provided with tools to help with areas of weakness. Outcomes were analyzed with descriptive and regression analyses (significance at p ≤ 0.05). RESULTS: A total of 116 patients were evaluated, with 80 patients (69.0%) recommended for transition. Median age at survey was 15.5 years [IQR: 13.7-18.1], and those recommended were older (16.6 years [IQR: 14.7-19.4] vs 13.5 years [IQR: 12.5-14.9], p < 0.001)). Primary diagnosis and gender were not associated with recommendation for transition. Overall, a minority (18.1%) were able to complete healthcare tasks; this correlated strongly with transition recommendation (26.3% vs 0.0%, p < 0.0001). On regression controlling for age, diagnosis, knowledge, and confidence, age (aOR 1.98, 95% CI 1.44-2.71) and confidence (aOR 3.78, 95% CI 1.29-11.11) independently predicted transition recommendation. CONCLUSION: A standardized approach may be effective in transitioning patients from pediatric to adult colorectal surgery practice. Patients who transition are more confident and can perform healthcare tasks independently; however, these skills are not essential prior to a recommendation of transition. LEVEL OF EVIDENCE: III.

Laxative Weaning Protocol for Patients With Functional Constipation: A Pilot Study.

BACKGROUND: Children with functional constipation require prolonged laxative administration for proper emptying. Whether these laxatives can be weaned after better functioning is achieved is unknown. We aim to describe a standardized protocol for stimulant laxative weaning and its early outcomes. METHODS: Patients were candidates for weaning if they had been on a stable laxative dose for six months, defined as one bowel movement per day with no soiling, impaction, or enemas. Laxative dose was decreased by 10-25% with re-evaluation every two weeks. If patients remained well without constipation, dose was weaned further by 10-25%. If there were worsening of symptoms, lower dose was maintained for 3-6 months until re-evaluation. RESULTS: There were a total of sixteen patients evaluated. Median age was 12.7 years [IQR: 11.7-15.3] with laxative duration of 8.0 years [IQR: 5.4-10.7]. All patients were on senna; some were on fiber. Median starting senna dose was 71.3 mg [IQR: 54.3-75.0] and median fiber dose was 5.5 g [IQR: 4.0-6.0]. As of most recent follow up, nine patients (56.3%) had weaned off laxatives in 3.7 months [IQR: 1.3-11.6]. For those still on laxatives, median reduction in dose was 41.4 mg [30.0-75.0], and over half weaned their dose by >50%. Almost all (90.9%) of those on high doses were able to wean. CONCLUSION: A standardized laxative weaning process can be successful in patients with functional constipation, especially on high doses. Further prospective studies will be necessary to confirm the success of this protocol. LEVEL OF EVIDENCE: III.

Social Determinants of Health Are Associated with Failed Bowel Management for Children with Anorectal Malformations.

INTRODUCTION: Children with anorectal malformations (ARMs) benefit from bowel management programs (BMPs) to manage constipation or fecal incontinence. We aimed to understand the role of social determinants of health (SDOH) in outcomes following BMPs in this population. MATERIALS AND METHODS: A single-institution, institutional review board (IRB) approved, retrospective review was performed in children with ARM who underwent BMP from 2014 to 2021. Clinical, surgical, and SDOH data were collected. Children were stratified as clean or not clean per the Rome IV criteria at the completion of BMP. Descriptive statistics were computed. Categorical variables were analyzed via Fisher's exact tests and continuous variables with Mood's median tests. RESULTS: In total, 239 patients who underwent BMP were identified; their median age was 6.62 years (interquartile range [IQR]: 4.78-9.83). Of these, 81 (34%) were not clean after completing BMP. Children with prior history of antegrade enema procedures had a higher rate of failure. Children who held public insurance, lived within driving distance, had unmarried parents, lived with extended family, and lacked formal support systems had a significant association with BMP failure (p < 0.05 for all). Type of ARM, age at repair, type of repair, age at BMP, and type of BMP regimen were not significantly associated with failure. CONCLUSIONS: There is a significant correlation of failure of BMPs with several SDOH elements in patients with ARM. Attention to SDOH may help identify high-risk patients in whom additional care may lead improved outcomes following BMP.

Development of a Standardized Algorithm for Management of Newly Diagnosed Anorectal Malformations.

Neonates with a new diagnosis of anorectal malformation (ARM) present a unique challenge to the clinical team. ARM is strongly associated with additional midline malformations, such as those observed in the VACTERL sequence, including vertebral, cardiac, and renal malformations. Timely assessment is necessary to identify anomalies requiring intervention and to prevent undue stress and delayed treatment. We utilized a multidisciplinary team to develop an algorithm guiding the midline workup of patients newly diagnosed with ARM. Patients were included if born in or transferred to our neonatal intensive care unit (NICU), or if seen in clinic within one month of life. Complete imaging was defined as an echocardiogram, renal ultrasound, and spinal magnetic resonance imaging or ultrasound within the first month of life. We compared three periods: prior to implementation (2010-2014), adoption period (2015), and delayed implementation (2022); p ≤ 0.05 was considered significant. Rates of complete imaging significantly improved from pre-implementation to delayed implementation (65.2% vs. 50.0% vs. 97.0%, p = 0.0003); the most growth was observed in spinal imaging (71.0% vs. 90.0% vs. 100.0%, p = 0.001). While there were no differences in the rates of identified anomalies, there were fewer missed diagnoses with the algorithm (10.0% vs. 47.6%, p = 0.05). We demonstrate that the implementation of a standardized algorithm can significantly increase appropriate screening for anomalies associated with a new diagnosis of ARM and can decrease delayed diagnosis. Further qualitative studies will help to refine and optimize the algorithm moving forward.

Inflammatory bowel disease-associated colorectal cancer negatively affects surgery outcomes and health care costs.

BACKGROUND: Inflammatory bowel disease may affect the pathogenesis and clinicopathologic course of colorectal cancer. We sought to characterize the impact of inflammatory bowel disease on outcomes after colectomy and/or proctectomy for a malignant indication. METHODS: Patients diagnosed with colorectal cancer as well as a pre-existing comorbid diagnosis of Crohn's disease or ulcerative colitis between 2018 and 2021 were identified from Medicare claims data. The postoperative textbook outcome was defined as the absence of complications, as well as no extended hospital stay, 90-day readmission, or mortality. Postdischarge disposition and expenditures were also examined. RESULTS: Among 191,684 patients with colorectal cancer, 4,770 (2.5%) had a pre-existing diagnosis of inflammatory bowel disease. Patients with inflammatory bowel disease-associated colorectal cancer were less likely to undergo surgical resection (no inflammatory bowel disease: 47.6% vs inflammatory bowel disease: 42.1%; P < .001). Among patients who did undergo colorectal surgery, individuals with inflammatory bowel disease were less likely to achieve a textbook outcome (odds ratio 0.64 [95% confidence interval 0.58-0.70]). In particular, patients with inflammatory bowel disease had higher odds of postoperative complications (odds ratio 1.24 [1.12-1.38]), extended hospital stay (odds ratio 1.41 [1.27-1.58]), and readmission within 90 days (odds ratio 1.56 [1.42-1.72]) (all P < .05). Patients with inflammatory bowel disease-associated colorectal cancer were less likely to be discharged to their home under independent care (odds ratio 0.77 [0.68-0.87]) and had 12.2% higher expenditures, which correlated with whether the patient had a postoperative textbook outcome. CONCLUSION: One in 40 patients with colorectal cancer had concomitant inflammatory bowel disease. Inflammatory bowel disease was associated with a lower probability of achieving ideal postoperative outcomes, higher postdischarge expenditure, as well as worse long-term survival after colorectal cancer resection.

Laparoscopic-Assisted Colonic Derotation in Patients With Hirschsprung Disease.

BACKGROUND: Children with Hirschsprung disease (HSCR) proximal to the splenic flexure or those needing a redo pull-through (PT) are at risk for tension and ischemia of the PT which could result in leak, stricture, or loss of ganglionated bowel. Colonic derotation is a technique used to minimize tension and avoid duodenal obstruction. The aim of this study was to describe this technique and outcomes in a series of patients requiring this intervention. METHODS: All patients underwent initial diversion and colonic mapping. The derotation procedure involves mobilization of the remaining colon, counterclockwise rotation via the stoma closure site, placement of the pull through (the right colon) lying on the right of the pelvis, and ligation of the middle colic artery with preservation of the marginal branch running from the ileocolic artery. This maneuver prevents compression of the duodenum by the mesenteric vessels and allows for an isoperistaltic, tension-free anastomosis. Intraoperative indocyanine green fluorescence angiography (ICG-FA) was utilized in many of the cases to map the blood supply of the pull-through colon. We reviewed outcomes for all children with HSCR who underwent colonic derotation from 2014 to 2023. Descriptive statistics were performed. RESULTS: There were 37 children included. Most were male (67.5%) with the original transition zone proximal to the rectosigmoid (81.1%). The median age at PT was 9.3 months [6.1-39.7]. Median operative time was 6.6 h [4.9-7.4] and 19 cases (51.4%) used ICG-FA. Most children had no 30-day postoperative complications (67.6%); in those who did develop complications, readmissions for electrolyte imbalance was most common (50.0%). There were zero cases of anastomotic leak at PT anastomosis. At long-term follow up, median 4.4 years [2.3-7.0], three children (8.1%) developed an anastomotic stricture, all were amenable to anal dilation, and five experienced episodes of enterocolitis (14.7%). Most children had between 1 and 4 stools per day (58.8%). CONCLUSION: Colonic derotation is a useful strategy to ensure well-perfused colonic length, protect the marginal artery blood supply, avoid duodenal compression, and ensure a tension-free anastomosis with minimal complications. TYPE OF STUDY: Original research, retrospective cohort. LEVEL OF EVIDENCE: III.

Long-term patient perception of pain control experience after participating in a trial between patient-controlled analgesia and epidural after pectus excavatum repair with bar placement.

BACKGROUND: Pain control is the dominant management issue after bar placement for pectus excavatum. We previously conducted a prospective, randomized trial comparing patient-controlled analgesia (PCA) to thoracic epidural (EPI) documenting similar objective outcomes. Our impression is that the subjective cognitive experience differs between the groups, which impacts trial results interpretation. Therefore, we conducted a survey to ascertain patient recollection and impression of their experience. METHODS: By telephone questionnaire, yes/no questions included early course recall, anxiety, if they would choose the same arm, do the operation again, or recommend it to friends. Qualitative questions included description, location, and time of peak pain. The graded question addressed severity of pain (1-5). RESULTS: We contacted 27 EPI and 38 PCA patients with a median follow-up of 3.2 y. The majority (~/= 85%) of both groups remembered the first 2 d. Mean pain severity was 3.0 in both groups (3 = bad, but tolerable). Description, location, and time of peak pain responses did not differ. Anxiety was reported by 30% of EPI group and 18% of PCA group (P = 0.37). Approximately 15% of both groups still think about the pain. No differences were seen in nausea, emesis, constipation, itching, or sleepiness. Most patients would choose the same group (87% PCA, 81% EPI, P = 0.73), have the operation again (87% PCA, 74% EPI, P = 0.21), and recommend the operation to friends (100% PCA, 96% EPI, P = 0.42). CONCLUSIONS: Long-term recall after repair of pectus excavatum with bar placement does not substantially differ between those managed with an epidural or PCA.

Need for subsequent fundoplication after gastrostomy based on patient characteristics.

BACKGROUND: Gastrostomy tube placement is common in children. Many of the conditions associated with need for gastrostomy are also associated with gastroesophageal reflux. It is not clear how many patients without complicated reflux will subsequently require a fundoplication or which conditions increase this risk. Therefore, we performed a two-center review to determine the disease-specific propensity for fundoplication after gastrostomy tube placement. METHODS: The data set was retrospectively collected from two centers from 2000 to 2008. All patients underwent gastrostomy tube placement without fundoplication owing to the surgeon's discernment that fundoplication was not needed at the time. Pearson's correlation was used to evaluate the influence of patient variables and operative approach against the subsequent need for fundoplication. Significance was defined as two-tailed P ≤ 0.01. Logistic regression analysis was used to evaluate independence. RESULTS: A total of 684 patients underwent gastrostomy tube placement only, of which 124 were open, 282 laparoscopic, and 278 endoscopic (percutaneous endoscopic gastrostomy). The mean patient age was 2.9 years. Subsequent fundoplication was performed in 62 patients (9.1%). The mean interval to fundoplication was 20.7 months. Cerebral palsy and anoxic brain injury had the most significant correlation with subsequent fundoplication. These were also independent predictors. The laparoscopic approach had a negative correlation with the subsequent need for fundoplication. CONCLUSIONS: The low incidence of subsequent fundoplication in children who undergo gastrostomy tube placement justifies conservative use of fundoplication in the absence of complicated reflux. Those with cerebral palsy and anoxic brain injury appeared to have the greatest risk of the need for subsequent fundoplication.

Ghost publications in the pediatric surgery match.

INTRODUCTION: Pediatric surgery fellowship is considered one of the most competitive subspecialties in medicine. With fierce competition increasing the stakes, publications and first authorship are paramount to the success rate of matching. We analyzed Electronic Residency Application Service applications for verification of authorship to determine rate of misrepresentation. METHODS: After institutional review board approval, the bibliographies of fellowship applications from 2007-2009 were reviewed to allow time for publication. Only peer-reviewed journal articles were evaluated. A Medline search was conducted for the article, by author or by title. If the article could not be found, other authors and journal were used as search parameters. If the article was still not found, the website for the journal was searched for abstract or manuscript. Finally, an experienced medical sciences librarian was consulted for remaining unidentified articles. Differences between misrepresented and accurate applications were analyzed, including: age, gender, medical and undergraduate school parameters, advanced degrees, other fellowships, number of publications, first author publications, American Board of Surgery In-Training Examination scores, and match success. RESULTS: There were 147 applications reviewed. Evidence of misrepresentation was found in 17.6% of the applicants (24/136), with 34 instances in 785 manuscripts (4.3%). Manuscripts classified as published were verified 96.7% of the time, were not found in 1.4%, and had incorrect authors or journal in less than 1% each. "In press" manuscripts were verified 88.3% of the time, 6.4% could not be found, and 4.3% had an incorrect journal listing. Number of publications (P = 0.026) and first author publications (P = 0.037) correlated with misrepresentation. None of the remaining variables was significant. CONCLUSIONS: The pediatric surgical pool has a very low incidence of suspicious citations; however, authorship claims should be verified.
