RESUMEN

BACKGROUND: Infantile hypertrophic pyloric stenosis (IHPS) is a condition whose etiology is not clear, but it is characterized by progressive hypertrophy of the circular muscles of the pylorus with consequent obstruction of the gastric outflow, mostly in neonates and infants under the age of one year. OBJECTIVES: To assess the treatment outcome and associated factors of infantile pyloric sphincter stenosis among paediatric patients admitted to HFCSUH and JUSHYRH. METHODOLOGY: A retrospective patient record review with 78 participants was studied consecutively using a structured questionnaire. The data was processed and analyzed using Epi Info 7 and SPSS version 24. Descriptive analysis was done, and then associated factors to the outcome were assessed using logistic regression analysis. The association's significance was determined using an odds ratio with a 95% confidence interval and a P-value less than 0.05. The study period was from November 1st to 30th, 2022. RESULTS: The magnitude of unfavorable IHPS was 17.1% with a 95% confidence interval of 16.7-23.9%. Hypokalemia (AOR = 2.3, CI = 3.015-19.54), severe dehydration (AOR = 30.9, CI = 2.89-31.75), and delayed presentation (AOR = 7.37, CI = 2.761-12.08) were independent predictors. CONCLUSIONS: The study found a highly unfavorable treatment outcome with delayed presentation; dehydration and electrolyte disturbance were the main predictors of poor outcome. It is recommended to increase community awareness about non-bilious vomiting in infants and ensure high suspicion among healthcare providers. Moreover, following guidelines to correct fluid and electrolyte disturbances and managing these patients in the pediatric ICU postoperatively.

RESUMEN

A 16-year-old girl with down syndrome came to our attention for recurrent postprandial vomiting and significant weight loss (>5 kgs). Diagnostic assessment (barium swallow study, ultrasonography, and CT) confirmed hypertrophic pyloric stenosis (HPS). Initial attempt with endoscopic dilation was not successful. The patient underwent Heineke-Mikulicz pyloroplasty. Full oral feeding was achieved by Day 7 postoperatively. At 6-month follow-up, the patient reported relief of symptoms, normal feeding habits and substantial weight gain. HPS should be considered in the differential diagnosis of recurrent vomiting, regardless of age. A comprehensive diagnostic work-up, including ultrasonography, endoscopy, and CT, is recommended to confirm the diagnosis.

RESUMEN

Eosinophilic gastritis, a rare variant of gastritis, presents with inflammation of the stomach lining due to eosinophil infiltration. This case report describes a complex presentation of eosinophilic gastritis in a 12-year-old boy, highlighting the challenges encountered in management. A 12-year-old male presented with symptoms consistent with gastritis, including abdominal pain, nausea, and vomiting. Despite extensive medical workup to identify potential etiologies (parasitic infections, autoimmune conditions), the diagnosis of eosinophilic gastritis was established. Unfortunately, the patient exhibited persistent symptoms despite aggressive medical management. The case was further complicated by pyloric stenosis, a narrowing of the stomach outlet. Laparoscopic intervention, a minimally invasive surgical approach, was initially attempted but deemed challenging due to the patient's specific condition. The presence of metabolic abnormalities added further complexity. Alternative approaches, such as endoscopic dilatation, were considered but ultimately deemed unsuitable due to the severity of the stenosis and the desire for a minimally invasive solution compared to laparotomy. This case exemplifies the challenges associated with managing rare gastrointestinal conditions like eosinophilic gastritis, particularly in pediatric patients. The report emphasizes the importance of a multidisciplinary approach, involving collaboration between gastroenterologists, surgeons, and potentially other specialists depending on the specific complications, to achieve optimal outcomes. This case highlights the complexities in managing this patient, especially when accompanied by complications like pyloric stenosis. It underscores the crucial role of a multidisciplinary team in navigating challenging presentations and exploring minimally invasive surgical options when feasible.

RESUMEN

Cytomegalovirus (CMV) has been extensively researched in immunocompromised people, causing conditions such as colitis, retinitis, esophagitis, encephalitis, and pneumonitis. However, there are limited data on how the disease presents itself in immunocompetent hosts, apart from a self-limited mononucleosis-like syndrome. This case report presents CMV gastroenteritis causing gastroduodenal obstruction in an immunocompetent woman. It is important to consider CMV as a potential cause of various gastric pathologies in immunocompetent people. Further research is necessary to establish guidelines for diagnosing and treating this pathogen.

RESUMEN

Infantile hypertrophic pyloric stenosis (IHPS) is a condition whereby there is a thickening of the pyloric muscle, leading to obstruction of the gastric outflow. Typically present within three to five weeks of life, it presents as postprandial non-bilious projectile vomiting. Commonly, a pyloromyotomy is the gold standard to relieve the obstruction. However, in a subset of patients not amenable to undergo surgery or anesthesia, or for postoperative persistent or recurrent obstruction, atropine may offer an alternative treatment. A retrospective review was performed on pediatric patients with hypertrophic pyloric stenosis utilizing the electronic medical record. Data included were demographics, workup data, treatment, outcomes, and symptom resolution. Approval was obtained by the institutional review board of the host institution. Five pediatric patients, with an average age of 2.1 months, received atropine treatment for IHPS. The average time to reach full feeds since the initiation of atropine was approximately four days. Three of the five patients were successfully managed with IV atropine, which was then transitioned to oral atropine and tapered off as outpatients, leading to the resolution of symptoms. The remaining two patients were considered failures of medical management and subsequently required surgery. Atropine use as an alternative treatment for IHPS may be considered when patients are not able to undergo surgery or anesthesia or have recurrent or persistent obstructive symptoms postoperatively. In this limited study, atropine was found to be safe and effective. Randomized controlled studies may lend additional merit to this therapy in the future.

RESUMEN

INTRODUCTION: We sought to determine the effectiveness and utility of two-dimensional shear-wave sonoelastography (2D-SW-SE) in the diagnosis and postoperative follow-up of infantile hypertrophic pyloric stenosis (IHPS). MATERIALS AND METHODS: Twenty-three infants were included in the study, 13 in the IHPS group and 10 in the control group (CG). Preoperative B-mode ultrasonography measurements (longitudinal length and single-wall thickness of the pylorus) and 2D-SW-SE measurements (pylorus tissue stiffness and shear-wave propagation speed) were compared between the groups. The infants with IHPS then underwent Ramstedt pyloromyotomy and were invited for follow-ups on the tenth day and the first, third, and sixth months postoperatively. Measurements taken at the follow-ups were compared with the preoperative values. RESULTS: No differences were found between the groups regarding age, gender, body weight, or week of birth. The pyloric lengths in the IHPS group were longer than in the CG (p < 0.001), and the single-wall thicknesses were thicker (p < 0.001). The pylorus in the IHPS group was four times stiffer than in the CG (27.4 kPa versus 7.66 kPa), and the shear-wave propagation speed in the tissue was higher (1.34 m/s versus 2.69 m/s; p < 0.001). Both values decreased over time in the IHPS group and were normal by the third postoperative month. CONCLUSIONS: 2D-SW-SE can be used as an assistive imaging tool alongside B-mode ultrasound for diagnosing IHPS. It can also be used to identify inadequate surgery by detecting whether the pyloric tissue has softened at follow-up.

RESUMEN

We present a rare neurocutaneous genetic disorder where patients develop a combination of cerebral dysgenesis, neuropathy, ichthyosis, and keratoderma, commonly known as CEDNIK syndrome. It is an autosomal recessive inheritance involving the SNAP29 protein, mapped to the 22q11.2 gene. Phenotypic variation is seen with this disease, with clinical manifestation of developmental milestone delays ranging in severity. With only a handful of documented cases, available research, management of the syndrome, and prognosis are not well established. As CEDNIK syndrome has systemic implications, care coordination between specialists is essential in improving patient outcomes. Particularly important is preventing patients from meeting the criteria of failure to thrive, a commonly reported issue. In this case, we present a four-month-old male with a past medical history of pyloric stenosis status/post pyloromyotomy who has failure to thrive, gastroesophageal reflux disease, profound hypotonia, and delayed progression of developmental milestones. Additionally, the case is complicated by idiopathic pyloric stenosis, further contributing to the patient's failure to thrive. We aim to discuss the pathophysiology of this syndrome, explore the timeline of disease progression, as well as compare our case to the current literature.

RESUMEN

The aim of this study was to compare the operative parameters and complication rates between the umbilical (UMB) and right upper quadrant (RUQ) skin incisions for Ramstedt's pyloromyotomy for the treatment of infantile hypertrophic pyloric stenosis (IHPS). PubMed, EMBASE, Web of Science and Scopus databases were systematically searched. The studies where any one of the main outcomes of interest, i.e., operative time, wound infection rate, mucosal perforation rate were reported were eligible for inclusion. The statistical analysis was performed using a random-effects model. The methodological quality of the studies was assessed utilizing the Newcastle-Ottawa Scale. Fifteen studies comprising 2964 infants were included. As compared to the UMB group, the RUQ group showed a significantly lower mean operative time (p = 0.0004), wound infection rate (p < 0.0001) and mucosal perforation rate (p = 0.02). Although UMB incision produces an almost undetectable scar, this approach results in significantly more complications. Therefore, the risks and benefits must be weighed and discussed with the caregivers in deciding the surgical approach in patients with IHPS. However, due to a poor methodological quality of nine out of fifteen studies, further studies need to be conducted for an optimal comparison between the two groups.

RESUMEN

The inflammatory status of patients is closely related to their nutritional status, and the impact of inflammatory status on patients with pyloric stenosis remains unclear. The present study aimed to investigate the impact of inflammatory status on the prognosis of patients with gastric cancer with early pyloric stenosis who underwent radical resection. A retrospective analysis included 242 patients with gastric cancer who underwent radical resection at the Affiliated Hospital of Southwest Medical University between July 2016 and December 2020. All patients were diagnosed with early pyloric stenosis. Correlation analysis was used to assess variations among different factors, and survival analysis was conducted to evaluate differences in overall survival (OS). To identify independent prognostic indicators, both univariate and multivariate Cox regression analyses were performed, addressing potential multicollinearity using Lasso analysis. Propensity score matching (PSM) was employed to eliminate potential confounding factors. Additionally, a prognostic risk model and nomogram based on inflammatory indicators were developed to comprehensively explore their impact on prognosis. Initial survival analysis revealed significant associations between neutrophil-to-lymphocyte ratio (NLR; χ2=10.522, P<0.001), systemic immune-inflammation index (SII; χ2=6.733, P=0.025), systemic inflammation response index (SIRI; χ2=15.490, P<0.001) and OS of the patients, while there was no significant survival difference among patients with different platelet-to-lymphocyte ratio (PLR; χ2=2.561, P=0.050). SIRI not only had the highest area under the curve but was also found to be an independent prognostic indicator (hazard ratio=1.851, P=0.046) in the present study. Following PSM on SIRI, a total of 174 patients were included in the subsequent analysis. Time-receiver operating characteristic and survival curves for SIRI after PSM consistently demonstrated its robust prognostic predictive capability. Furthermore, the prognostic risk model based on SIRI and the nomogram incorporating SIRI both exhibited high prognostic value. Inflammatory status was significantly associated with the prognosis of patients with gastric cancer with early pyloric stenosis who underwent radical resection. The NLR, SII and SIRI could all predict patient outcomes. Moreover, SIRI exhibited the highest prognostic value among the inflammatory indices and has been identified as an independent prognostic factor in the present study.

RESUMEN

INTRODUCTION: Laparoscopic pyloromyotomy (LP) for the treatment of infantile hypertrophic pyloric stenosis (IHPS) is a clean case with low expected rates of postoperative surgical site infection (SSI). Previous studies have shown a low risk of SSI following LP but also large variations in the utilization of prophylactic antibiotics. The goal of this study was to review the use of preoperative antibiotics for LP and to compare this with SSI incidence. METHODS: We performed a retrospective single-center analysis of patients undergoing LP for infantile hypertrophic pyloric stenosis at a large quaternary children's hospital from January 2017 to June 2020. Subjects were <4 mo old. Exclusion criteria were those lost to follow-up within 30 d postoperatively and those who required open conversion intraoperatively. Statistical analysis was performed using Fisher's exact test, two-tailed independent t-tests, and descriptive statistics. RESULTS: Two-hundred twenty-seven patients were included, mean population age was 5.7 wk, and 81.1% were male. Preoperative antibiotics were administered in 39% of patients. Only 1.3% (n = 3) of all patients developed an SSI within 30 d of their operation. Analysis between patients who received preoperative antibiotics and those who did not revealed no difference in age (5.72 wk versus 5.72 wk, t (225) = 0.38, P = 0.70), sex (41% of males versus 32% of females, P = 0.39), length of stay (t(225) = -0.94, P = 0.35), or postoperative SSI (1.1% versus 1.4%, P > 0.999). Large variability was noted in antibiotic utilization by surgeon. CONCLUSIONS: In patients undergoing LP, there was no difference in SSI rates whether or not patients received preoperative antibiotics and, there is large variation in utilization. Measures are needed to decrease usage of prophylactic antibiotics before LP.

RESUMEN

Pyloric stenosis commonly affects infants and rarely causes gastric outlet obstruction in adolescents and older children. We present the case of an 11-year-old girl with a 2-month history of recurrent postprandial vomiting and weight loss. On physical examination, the patient presented with abdominal distension. Upper gastrointestinal endoscopy revealed a very small pyloric orifice through which the endoscope could not be advanced. Abdominal ultrasonography and a computed tomography confirmed pylorus thickening. She underwent Heineke-Mikulicz pyloroplasty with symptom resolution.

RESUMEN

PURPOSE: Infantile hypertrophic pyloric stenosis (IHPS) is suspected to have worse outcomes when length of illness prior to presentation is prolonged. Our objective was to evaluate how social determinants of health influence medical care and outcomes for babies with IHPS. METHODS: A retrospective review was performed over 10 years. Census data were used as proxy for socioeconomic status via Geo-Identification codes and correlated with food access and social vulnerability variables. The cohort was subdivided to understand the impact of Medicaid Managed Care (MMC). RESULTS: The cohort (279 cases) was divided into two groups; early group from 2011 to 2015 and late from 2016 to 2021. Cases in the late group were older at the time of presentation (41.5 vs. 36.5 days; p = 0.022) and presented later in the disease course (12.8 vs. 8.9 days; p = 0.021). There was no difference in race (p = 0.282), gender (p = 0.874), or length of stay. CONCLUSIONS: Patients who presented with IHPS after implementation of phased MMC were older, had a longer symptomatic course, and shorter pylorus measurements. Patients with public insurance after the implementation of MMC were more likely to follow-up with an outpatient pediatrician within a month of hospitalization. These results suggest that MMC may have improved access to care for infants with IHPS.

RESUMEN

Gastric peroral endoscopic myotomy (G-POME) is an emerging minimally invasive endoscopic technique involving the establishment of a submucosal tunnel around the pyloric sphincter. In 2013, Khashab et al used G-POME for the first time in the treatment of gastroparesis with enhanced therapeutic efficacy, providing a new direction for the treatment of gastroparesis. With the recent and rapid development of G-POME therapy technology, progress has been made in the treatment of gastroparesis and other upper digestive tract diseases, such as congenital hypertrophic pyloric stenosis and gastric sleeve stricture, with G-POME. This article reviews the research progress and future prospects of G-POME for the treatment of upper digestive tract gastrointestinal diseases.

RESUMEN

Purpose: Infantile hypertrophic pyloric stenosis (IHPS) is a common gastrointestinal disease in neonates and hypochloremia metabolic alkalosis is a typical laboratory finding in affected patients. This study aimed to analyze the clinical characteristics of infants with IHPS and evaluate the association of clinical and laboratory parameters with ultrasonographic findings. Methods: Infants diagnosed with IHPS between January 2017 and July 2022 were retrospectively evaluated. Results: A total of 67 patients were included in the study. The mean age at diagnosis was 40.5±19.59 days, and the mean symptom duration was 11.97±9.91 days. The mean pyloric muscle thickness and pyloric canal length were 4.87±1.05 mm and 19.6±3.46 mm, respectively. Hyponatremia and metabolic alkalosis were observed in five (7.5%) and 36 (53.7%) patients, respectively. Serum sodium (p=0.011), potassium (p=0.023), and chloride levels (p=0.015) were significantly lower in patients with high bicarbonate levels (≥30 mmol/L). Furthermore, pyloric canal length was significantly higher in patients with high bicarbonate levels (p=0.015). To assess metabolic alkalosis in IHPS patients, the area under the receiver operating characteristic curve of pyloric canal length was 0.910 and the optimal cutoff value of the pyloric canal length was 23.5 mm. Conclusion: We found a close association between laboratory and ultrasonographic findings of IHPS. Clinicians should give special consideration to patients with pyloric lengths exceeding 23.5 mm and appropriate fluid rehydration should be given to these patients.

RESUMEN

Eosinophilic gastritis is a gastrointestinal disorder characterized by eosinophilic infiltration in the gastric wall. We present a rare case of critical pyloric stenosis secondary to eosinophilic gastritis in a 16-year-old adolescent girl who presented with nausea, vomiting, early satiety, and abdominal pain. Abdominal computed tomography and subsequent esophagogastroduodenoscopy confirmed the anatomical diagnosis, but histological confirmation of the eosinophilic etiology was challenging. After an unsuccessful trial of high-dose systemic corticosteroids, a laparoscopic gastrojejunostomy was performed and long-term immunosuppression with mycophenolate mofetil was commenced.

RESUMEN

Pylorospasm is an elusive diagnosis that can mimic the presentation of pyloric stenosis. There is limited discussion regarding its management in neonates with few case reports describing the use of antispasmodic agents. The following case reviews this management in a unique neonate. A 2-month-old female presented with persistent nonbilious, nonbloody emesis and failure-to-thrive. A thorough workup was performed due to its pronounced persistence while inpatient. Pyloric ultrasounds remained negative for pyloric stenosis; however, an upper gastrointestinal (GI) study was significant for pylorospasm. The workup also revealed hypothyroidism. Antispasmodic therapy with atropine was pursued as she was not a surgical candidate. Patient tolerated IV atropine therapy well with quick resolution of emesis and successfully transitioned to oral atropine therapy, displaying continued weight gain with exclusive oral feeds. This case displays a unique presentation of pylorospasm with successful management utilizing IV and oral atropine therapy in a neonate with failure-to-thrive and concomitant hypothyroidism.

RESUMEN

BACKGROUND: Definitive surgical care is often delayed in hypertrophic pyloric stenosis (HPS). Our aim is to evaluate the effect modifiable factors in preoperative HPS management have on efficiency of care. METHODS: A retrospective review of all patients undergoing pyloromyotomy for HPS at two US children's hospitals between 2008 and 2018 was performed. RESULTS: 406 patients were included in the study. The majority (310, 76 â€‹%) were adequately resuscitated and ready for surgery upon diagnosis in the ER. However, only 133 patients (43 â€‹%) had surgery on the day of admission. Patients diagnosed between 12pm and 6pm were more likely to have surgery the next day than those diagnosed before noon (67 â€‹% vs 33 â€‹%, p â€‹< â€‹.001), which correlated with a longer length of stay (32 vs 47 â€‹h, p â€‹< â€‹.001). CONCLUSION: The majority of patients presenting with HPS can safely undergo same day surgery. Delaying surgery due to an afternoon diagnosis is common, and leads to a modifiable increased total length of stay.

RESUMEN

BACKGROUND: Ultrasound is the modality of choice for the diagnosis of hypertrophic pyloric stenosis (HPS). The evolution of high-frequency transducers in ultrasound has led to inconsistent ways of measuring the pylorus. OBJECTIVE: To standardize the measurements and evaluate the appearance of the normal and hypertrophied pylorus with high-frequency transducers. MATERIALS AND METHODS: We retrospectively analyzed abdominal ultrasounds of infants with suspected HPS from January 2019-December 2020. We classified the layers of the pylorus while assessing the stratified appearance. Two pediatric radiologists measured the muscle thickness of the pylorus independently by two methods for interrater agreement. Measurement (a) includes the muscularis propria and muscularis mucosa. Measurement (b) includes only the muscularis propria. We also evaluated the echogenicity of the muscularis propria. The interrater agreement, mean, range of the muscle thickness, and the diagnostic accuracy of the two sets of measurements were calculated. RESULTS: We included 300 infants (114 F:186 M), 59 with HPS and 241 normal cases. There was a strong agreement between the readers assessed in the first 100 cases, and ICC was 0.99 (95% CI, 0.98-0.99). Measurement (a), median thickness is 2.4 mm in normal cases and 4.8 mm in HPS. Measurement (b), median thickness is 1.4 mm in normal cases and 4.0 mm in HPS. Measurement (a) has an accuracy of 89.7% (95% CI, 85.7-92.8%) with 98.3% sensitivity and 87.6% specificity. Measurement (b) has an accuracy of 98.0% (95% CI, 95.7-99.3%) with 89.8% sensitivity and 100.0% specificity. The pylorus stratification is preserved in all normal cases and 31/59 (52.5%) cases of HPS. There was complete/partial loss of stratification in 28/59 (47.5%) cases of HPS. In all HPS cases, the muscularis propria was echogenic. CONCLUSION: Measuring the muscularis propria solely has a better diagnostic accuracy, decreasing the overlap of negative and positive cases. The loss of pyloric wall stratification and echogenic muscularis propria is only seen in HPS.

RESUMEN

Infantile hypertrophic pyloric stenosis is a common surgical disease in infants, with an incidence of 2 to 5 cases per 1000 live births. It often presents with nonbilious projectile vomiting after feeding and a mid-epigastric mass in infants between the third and eighth weeks of life. Ramstedt pyloromyotomy remains the gold standard of treatment. Postoperative emesis is common; however, further evaluation for incomplete pyloromyotomy and recurrent pyloric stenosis should be conducted with prolonged, or new-onset postoperative emesis. While repeat pyloromyotomy is the standard of care for infants presenting with incomplete pyloric stenosis, treatment for the rare development of recurrent pyloric stenosis is not clearly outlined. Here, we report a successful balloon dilation procedure in an 8-week-old female with recurrent pyloric stenosis three and a half weeks after the initial laparoscopic pyloromyotomy.

RESUMEN

Introducción: La hipertrofia del esfínter pilórico (EHP) es una condición que se caracteriza por la obstrucción del vaciamiento gástrico fisiológico y se considera una patología de resolución quirúrgica. Objetivo: Realizar la caracterización de los pacientes con hipertrofia congenita del píloro atendidos en el Hospital Regional de la Orinoquía entre 2010 y 2020. Metodología: Estudio observacional, descriptivo y retrospectivo en el cual se incluyeron los pacientes que consultaron al Hospital Regional de la Orinoquía entre el 01 de enero del 2010 y el 31 de diciembre del 2020 y que presentaron diagnóstico de hipertrofia congenita del píloro, identificados mediante los códigos CIE 10. Resultados: En total, se incluyeron 18 pacientes que cumplían con los criterios de selección. El promedio de edad de los participantes fue de 24,3 días de edad. La mayoría eran varones, asimismo, dos pacientes presentaban sobrepeso al nacer. El síntoma predominante fue la emesis posprandial en un 100 %. El diagnóstico se realizó mediante las medidas del píloro con ecografía abdominal y a la totalidad de los pacientes se les realizó piloromiotomía, de los cuales uno solo requirió una reintervención, sin embargo, ningún paciente falleció. Conclusiones: La hipertrofia congenita del píloro es una entidad patológica poco común, su síntoma clínico cardinal es la emesis postprandial. El método diagnóstico por excelencia es el estudio ecográfico. A pesar de su complejidad, esta entidad patológica tiene un buen pronóstico a corto y largo plazo.

Introduction: Hypertrophic pyloric stenosis (HPS) is a condition that is characterized by the obstruction of physiological gastric emptying and is considered a surgically-resolved pathology. Objective: To characterize patients with congenital hypertrophy of the pylorus treated at the Regional Hospital of Orinoquía between 2010 and 2020. Methods: Observational, descriptive and retrospective study of patients who were admitted at the Orinoquía Regional Hospital between January of 2010 and December of 2020. The patients that were included had a diagnosis of hypertrophic pyloric stenosis identified by the ICD-10 codes. Results: A total of patients were included by selection criteria. The average age of participants was 24.3 days old. Most of them were males and 2 patients were overweight at birth. The most common symptom was postprandial emesis in 100%. The diagnosis was made through measurements of pylorus measured with abdominal ultrasound. All the patients performed pyloromyotomy, and only one required a surgical reintervention, however, the mortality was 0. Conclusions: Congenital hypertrophy of pylorus is an uncommon pathology, whose cardinal symptom is postprandial emesis. The ideal diagnostic method is an ultrasound study. Despite its complexity, this pathology has a good short and long-term prognosis.
