Abdominal surgical emergencies in infants and young children

Complicated appendicitis wrongly diagnosed as nonspecific diarrhea: ways to decrease this continuous threat

BACKGROUND

The diagnostic assessment of right lower quadrant pain in children and adolescents is still a challenge. The aim of this study was to analyze the cases of complicated appendicitis wrongly diagnosed as nonspecific diarrhea, and based on the information obtained suggest a clear and simple policy in order to decrease misdiagnosis in the future.

METHODS

Three groups of patients were analyzed: children who underwent appendectomy (group 1); those with gastroenteritis (group 2), and those who underwent appendectomy following hospitalization under the wrong diagnosis of gastroenteritis (group 3).

RESULTS

Group 3 presented a more prolonged and complicated clinical course, higher fever, diffuse abdominal pain, repeat vomiting, higher C-reactive protein values, longer surgery duration and recovery.

CONCLUSIONS

When the etiology of right lower quadrant abdominal pain is not immediately evident and associated with atypical diarrhea, high fever, repeat vomiting, and significantly increased CRP values, early surgical consultation is required. If the clinical findings are unclear, an abdominal US should be performed as soon as possible. A limited abdominal computed tomography scan CT should follow those cases not resolved by history, physical examination, blood tests, and abdominal ultrasound.

Can Neutrophil-Lymphocyte Ratio in Complete Blood Count Help in the Differential Diagnosis Between Acute Appendicitis and Right Ureteral Stones in Pediatric Age Groups?

Background and objective

Abdominal pain is one of the most common problems in children presenting to the pediatric emergency departments and is often a diagnostic challenge for the physician. Clinical studies have been carried out on adult patients to differentiate between ureteral stones and acute appendicitis (AA) in which neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) were analyzed in the complete blood count, and it was found that NLR and PLR could help in the differential diagnosis. In this study, we investigated whether complete blood count parameters in pediatric patients could be helpful in the differential diagnosis between AA and right ureteral stones.

Methods

The files of pediatric patients who were followed up and treated for AA and right ureteral stones between January 2019 and March 2021 were reviewed retrospectively. The demographic characteristics of the patients and their WBC, NLR, PLR, and red cell distribution width (RDW) values were evaluated to determine whether there was a difference between the two groups.

Results

In this study, 77 patients with AA and 48 patients with right ureteral stones were included. Univariate regression analysis revealed that age, gender, WBC, PLR, and NLR were factors likely responsible for AA. As per multivariate linear regression analysis, NLR level (odds ratio: 0.407; 95% CI: 0.293-0.566; p<0.001) was an independent predictor of AA.

Conclusion

Based on our findings, NLR can help in establishing the diagnosis in pediatric patients who present to the emergency department with right lower quadrant pain, and in whom physical examination, routine laboratory tests, and imaging methods cannot help distinguish between AA and ureteral stones.

Same-day discharge vs. observation after laparoscopic pediatric appendectomy: a prospective cohort study

Background

Through 2015, the practice at our university based free-standing children's hospital was to admit uncomplicated appendicitis patients for overnight observation post-operatively. Given the increasing body of evidence suggesting the safety and feasibility of same-day discharge after appendectomy for uncomplicated appendicitis, we elected to perform a prospective study evaluating the complication rates of same-day discharge compared to overnight observation at our institution, given our large volume of appendicitis.

Methods

Pediatric patients who underwent laparoscopic appendectomies for uncomplicated appendicitis in 2016 were analyzed. Data regarding demographics, admission, and discharge times and outcomes of complications, as well as readmissions, return to the emergency department, and nonscheduled clinic visits were collected and analyzing using chi-square and multivariate regression. Cost of stay data was obtained and analyzed using Mann-Whitney U test to compare non-parametric variables.

Results

Eight hundred and forty-nine laparoscopic appendectomies were performed for uncomplicated appendicitis during the study period, of which 382 resulted in same-day discharge and 467 in an admission for observation. Univariate analysis revealed no statistical difference between readmission rates for same day vs. observation (2 vs. 6 patients; P=0.21) or in emergency department visits within 30 days (22 vs. 27 patients; P=0.98). There was no difference in the number of surgical site infections or extra clinic visits. There was a significantly lower median cost of stay for patients discharged home the same day at 29,150 dollars (25,644, 32,276, IQR) compared to a median of 34,827 dollars (31,154, 39,457, IQR) (P<0.0001).

Conclusions

Same-day discharge for laparoscopic uncomplicated appendectomy should be the new standard of care. This study found no differences in outcomes between the timing of discharge, with a significantly lower cost of stay for patients discharged home the same day.

Concurrent COVID-19 infection in children with acute appendicitis: A report of three cases

Literature describing patients with concomitant COVID-19 infection with acute appendicitis in pediatric patients is growing, and understanding the clinical picture of such patients is relevant in their treatment. We report 3 male children who were surgically treated for acute appendicitis and had concomitant SARS-CoV-2 infection. Our first patient was a 12-year-old male who presented with symptoms indicative of appendicitis but no respiratory symptoms associated with COVID-19 (eg cough, shortness of breath). Laboratory evaluation revealed leukopenia and an elevated C-reactive protein; imaging was consistent with acute appendicitis and an acute pulmonary viral infection. Though he lacked diffuse peritonitis on physical examination or a leukocytosis, he was found to have perforated appendicitis in the operating room. Our second patient was another 12-year-old male whose suspected appendicitis was confirmed via ultrasound and surgery. He tested positive for COVID-19 1 month prior and he continued to test positive for infection on admission without any associated respiratory symptoms. Our third patient was a 13-year-old patient who also presented with symptomatic acute appendicitis without apparent COVID-19 manifestations. These cases provide further examples of pediatric patients with concomitant acute appendicitis and COVID-19 infection, namely an unusual presentation of perforated appendicitis with asymptomatic COVID-19-related pulmonary infection and the more common acute appendicitis with asymptomatic COVID-19 infection.

Ileocolic Intussusception Accompanied with Inflamed Appendix: 2 Case Reports

Intussusception and acute appendicitis are common emergency conditions in children. They should be promptly differentiated in pediatric patients presenting with suggestive symptoms. However, both diseases may occur simultaneously. Herein, we present two cases of intussusception of the appendix accompanied with appendicitis.

Parental satisfaction with same-day discharge after laparoscopic appendectomy for uncomplicated appendicitis

Objectives

Recent studies suggest that same-day discharge is safe for the paediatric population after various laparoscopic procedures. Same-day discharge is increasingly common after laparoscopic surgery for uncomplicated appendicitis although it is not standard practice. This prospective study aims to assess parental satisfaction with same-day discharge after laparoscopic appendectomy for uncomplicated appendicitis.

Methods

At our institution, 849 patients with uncomplicated acute appendicitis underwent laparoscopic appendectomy in 2016; of which, 382 were discharged on the same calendar day. Postdischarge surveys assessing parental satisfaction were administered by telephone at the 2-week follow-up.

Results

Approximately 65% of 185 total parental responses reported initial satisfaction with same-day discharge. About 30% were nervous at that time, and 5% did not feel ready to go home yet. Upon reflection, a higher proportion of parents (81.6%) felt same-day discharge was the appropriate course of action, 11.4% were unsure, and 7.0% would not do it again. Some parents cited concerns regarding pain control and incongruous expectations from conversations with staff or surgical experiences of their own.

Conclusions

The majority of parents recalled being happy at discharge, with an increase to 82% retrospectively. Only 7% of parents would not elect to go home on the same day again. Opportunities for improvement include a unified plan from all providers with expectations of same-day discharge if appendicitis is intraoperatively confirmed to be uncomplicated and better analgesic instructions at discharge.

Characteristics of intussusception among children in Korea: a nationwide epidemiological study

Background

Intussusception is a gastrointestinal condition in which early treatment is critical. Although its epidemiology and comorbidities have been studied, few studies have included the entire pediatric population of a country. Therefore, we aimed to analyze the epidemiologic features of pediatric intussusception patients and identify comorbidities associated with intussusception in South Korea, using the public health database.

Methods

We analyzed the data of children below 18 years of age, from the national database of South Korea, who were diagnosed with intussusception and managed such as air reduction or surgical methods from 2008 to 2016. Patients were categorized into six groups based on the comorbid diseases. Patients with structural lesion in gastrointestinal tract were divided diagnosis or diagnosis code.

Results

The number of patients diagnosed with intussusception were 25,023 (16,024 males, 64.0%). Of them, the highest percentage was patients aged between 2 and 36 months (20,703; 82.7%). The incidence per 100,000 individuals aged up to 2 years was 196.7. The number of males were 16,024 (64.0%) and were almost twice the number of 8999 (36.0%) female patients. The maximum number of cases (n = 2517; 10.1%) were seen in September, followed by July (n = 2469; 9.9%). In February, the number of cases was lowest at 1448 (5.8%) patients (P < 0.001). The number of patients with structural lesions of the gastrointestinal tract that could lead to intussusception was 1207 (4.8%), while patients with acute gastrointestinal infectious disease were 4541 (18.1%). Among the structural lesions of the gastrointestinal tract that could be the leading cause of intussusception, lymphadenopathy was the most common, seen in 462 (56.6%) patients and an appendix-related condition was seen in 260 (31.9%) patients. Infectious diseases were more common in the younger children, while systemic diseases were more common in the older.

Conclusion

We confirmed that pediatric intussusception in South Korea shows a seasonal tendency, which is age-dependent and is associated with an exposure to infectious agents. Some infectious pathogens and underlying diseases might play an important role in the pathophysiology of intussusception.

Clinical and Ultrasonographic Diagnosis of Acute Appendicitis

Appendicitis is one of the most common acute abdominal conditions encountered in the Emergency Department. It is a surgical condition that can affect any person of any age and often with varying clinical presentations. In the majority of cases, the diagnosis is straightforward. However in some, the diagnosis requires a heightened clinical suspicion. The application of adjuvant laboratory tests and diagnostic imaging helps to reduce the associated complications, morbidity and mortality of delayed diagnosis.

A Case of Intussusception with Acute Appendicitis

In children presenting to hospital with gastrointestinal symptoms, diseases such as intussusception and acute appendicitis require particular attention and careful examination. Early diagnosis and proper treatment are important because of possible severe complications such as peritonitis and death. Intussusception and appendicitis share similar clinical manifestations. More importantly, the presence of acute appendicitis together with intussusception in children is very rare. We describe an interesting case of a 38-month-old boy who presented with abdominal pain in the right lower quadrant. His vital signs were stable and laboratory test findings showed no specific alterations. We detected tenderness in the right lower quadrant. A computed tomography scan showed an ileocolic intussusception with no strangulation and diffuse wall thickening of the appendix trapped within the intussusception. The patient underwent an appendectomy and manual reduction.

Intra-abdominal sepsis--epidemiology, aetiology and management

Peritonitis is a progressive disease leading inexorably from local peritoneal irritation to overwhelming sepsis and death unless this trajectory is interrupted by timely and effective therapy. In children peritonitis is usually secondary to intraperitoneal disease, the nature of which varies around the world. In rich countries, appendicitis is the principal cause whilst in poor countries diseases such as typhoid must be considered in the differential diagnosis. Where resources are limited, the clinical diagnosis of peritonitis mandates laparotomy for diagnosis and source control. In regions with unlimited resources, radiological investigation, ultrasound, CT scan or MRI may be used to select patients for non-operative management. For patients with appendicitis, laparoscopic surgery has achieved results comparable to open operation; however, in many centres open operation remains the standard. In complicated peritonitis "damage control surgery" may be appropriate wherein source control is undertaken as an emergency with definitive repair or reconstruction awaiting improvement in the patient's general condition. Awareness of abdominal compartment syndrome is essential. Primary peritonitis in rich countries is seen in high-risk groups, such as steroid-dependent nephrotic syndrome patients, whilst in poor countries the at-risk population is less well defined and the diagnosis is often made at surgery.

Clinical signs and symptoms associated with intussusception in young children undergoing ultrasound in the emergency room

OBJECTIVE

The purpose of this study was to evaluate all patients suspected of having intussusception and identify which signs and symptoms were associated with the disease.

METHODS

We performed a retrospective review of 553 charts from 2006 to 2010 of patients' age 2 months to 5 years who had an abdominal ultrasound obtained to evaluate for intussusception. Charts were reviewed for signs and symptoms previously shown to be associated with intussusception.

RESULTS

There were 452 patients (mean age, 21.5 months, 43% female) evaluated and 101 (22.3%) were found to have intussusception. Of the 18 signs and symptoms, crying (adjusted odds ratio [OR], 3.3; 95% confidence interval [95% CI], 1.3-8.1), abdominal mass (adjusted OR, 15.7; 95% CI, 4.4-55.3), pallor (adjusted OR, 6.5; 95% CI, 1.8-23.5), and vomiting (adjusted OR, 3.1; 95% CI, 1.4-6.5) were associated with disease confirmation in logistic regression analysis. The presence of all 4 clinical signs/symptoms together resulted in a 95% probability of intussusception. Intussusception was unlikely if all 4 clinical indicators were absent (probability = 1.6%).

CONCLUSIONS

The presence of crying, abdominal mass, pallor, and vomiting were clinical indicators of intussusception. Individually, none of these variables were helpful in confirming the diagnosis but in the presence of all 4, there is a 95% probability of having the disease. The absence of all 4 of these made the likelihood of having the disease very low.

Critical urologic skills and procedures in the emergency department

The evaluation and management of genitourinary emergencies is a fundamental component of the training and practice of emergency physicians. Urologic procedures are common in the emergency room. Emergency physicians play a vital role in the initial evaluation and treatment because delays in management can lead to permanent damage. This article discusses the most common urologic procedures in which emergency physicians must be proficient for rapid intervention to preserve function and avoid complications. An overview of each procedure is discussed as well as indications, contraindications, equipment, technique, and potential complications.

Transmesenteric hernia due to double-loop formation in the small intestine: a fatal case involving a toddler

We report a unique case of transmesenteric hernia resulting in death, which went undiagnosed during a recent hospital visit. The victim was a 2.5-year-old girl who - with the exception of chronic constipation - had no medical history. One night she complained of abdominal pains and was taken to a pediatric hospital where doctors performed an abdominal X-ray and echography. No significant findings suggesting bowel obstruction (e.g. air-fluid levels or dilation of the bowel) were obtained on examinations and bloody feces were not observed in this particular episode. As her abdominal pain gradually attenuated, the doctor allowed her to return home. A few hours later, she lost consciousness and expired despite resuscitation efforts attempted at an emergency hospital. A subsequent autopsy revealed that the small bowel had herniated through a defect in the mesentery resulting in two consecutive and inversely forming loops, in which each loop protruded on either side of the mesentery. This rare morphological anatomy seems to have progressed in a two-step process. The girl's mild abdominal pain was likely induced by herniation and formation of the first intestinal loop, followed by severe shock occurring when the subsequent intestinal segment invaginated into the same defect forming the second loop on the opposite side of the mesentery. This case illustrates the difficulty of diagnosing transmesenteric hernia due to the presentation of unspecific symptoms; especially in infants and toddlers. Furthermore, this report demonstrates the value of a complete autopsy in cases of sudden and unexpected deaths involving children.

Systemic causes of abdominal pain

A variety of systemic and extra-abdominal diseases can cause symptoms within the abdominal cavity. Systemic and extra-abdominal diseases may include abdominal symptoms caused by several mechanisms. This article discusses the most important and common of these causes, namely the metabolic/endocrine causes, hematologic causes, inflammatory causes, infectious causes, functional causes, and the neurogenic causes.

Abdominal pain in children

Abdominal pain is one of the most common reasons pediatric patients seek emergency care. The emergency physician must be able to distinguish diagnoses requiring immediate attention from self-limiting processes. Pediatric patients can be challenging, particularly those who are preverbal, and therefore, the clinician must rely on a detailed history from a parent or caregiver as well as a careful physical examination in order to narrow the differential diagnosis. This article highlights several pediatric diagnoses presenting as abdominal pain, including surgical emergencies, nonsurgical diagnoses, and extraabdominal processes, and reviews the clinical presentation, diagnostic evaluation, and management of each.

Internal hernia associated with Meckel's diverticulum in 2 pediatric patients

We report 2 pediatric cases of small bowel obstruction due to a Meckel's diverticulum complicated with internal hernia. Abdominal multidetector computed tomograms with multiple planar reconstructions revealed a bridge-like lesion with inconspicuous mucosal folds in the right lower quadrant formed by adhesion of the tip of Meckel's diverticulum with the adjacent mesentery, with ileal loops converging at the "bridge" and engorged mesenteric vessels. These 2 cases highlight the feasibility of multidetector computed tomography, especially in the ED, in revealing this unusual etiology of small bowel obstruction.

A Rare but Serious Complication of Ladd's Procedure: Recurrent Midgut Volvulus

An eighteen-month-old boy who had undergone a Ladd's procedure for malrotation in the newborn period presented with acute onset of nausea, vomiting, rectal bleeding, and confusion. Laparotomy revealed midgut volvulus, mesenteric lymphadenopathy and massive chylous ascites. Recurrent midgut volvulus following Ladd's procedure is extremely rare but should be borne in mind in cases of persistent or recurrent gastrointestinal symptoms. Timely surgery is necessary to avoid intestinal gangrene and decrease morbidity and mortality related to consequences of midgut volvulus.

Testicular Torsion

Testicular torsion is described as the twisting of the spermatic cord resulting in acute pain and ischemia. This has a tendency to occur more frequently during adolescence and its cause is unknown. The most common signs and symptoms include red, swollen scrotum and acutely painful testicle, often in the absence of trauma. Nausea and vomiting are common. The most common conditions in the differential diagnosis include epididymitis, strangulated inguinal hernia, traumatic hematoma, testicular tumor, or testicular fracture. Physical examination techniques such as scrotal elevation can be helpful in differentiating between epididymitis and testicular torsion, but emergent imaging with Doppler ultrasound seems to be the most helpful in confirming the diagnosis. Radionuclide testicular scintigraphy with 99mTc is helpful when past the acute phase (the first 12 hours) and vascular compromise has prolonged. The clinician may attempt to manually reduce the torsion, but many need to be immediately referred to a urologist for a surgical exploration. Long-term prognosis for a functional, nonatrophied testicle is improved the sooner the torsion is diagnosed and treated.

Emergency management of collapsed infants

Infants have a limited repertoire of clinical signs in severe illness. Lethargy, respiratory distress, apnoea and poor perfusion can result from a wide spectrum of disorders. Fortunately for the emergency physician, the resuscitation of infants with respiratory and/or circulatory collapse remains universal for all aetiologies (Table 1). Investigations can be initiated during the stabilization of the child that will narrow the differential diagnosis. This article will discuss the resuscitation of collapsed infants, the causative disorders in the first few weeks of life, their early investigation and management.
