Rectal biopsy: is it really necessary in anorectal malformations?

AIM OF THE STUDY: The coexistence of Hirschsprung's disease (HD) with anorectal malformation (ARM) is rare but many surgeons still ask pathologists to look for ganglia in the terminal rectum or fistula. In this study, we aimed to highlight the rarity of this association and question the necessity of histological evaluation. METHODS: After obtaining board review approval, rectal specimens of ARM patients who underwent corrective surgery in the last 8 years were re-analyzed by two blinded pathologists for the presence and structure of ganglia. Clinical and radiological data of patients retrieved from center records and correlated with histopathologic findings. MAIN RESULTS: 67 patients with ARM were identified, distal rectal specimen was obtained in 47. The median age at the time of surgery was 11 months (2 days-59 months). A normal pattern of ganglia was present in 51.1% (24/47), 29.7% (14/47) had aganglionosis and 19.1% (9/47) were inconclusive due to insufficient material. None of the aganglionic specimens showed other histological findings of HD. Patients were followed up regularly in the outpatient colorectal clinic for a median of 87 months (42-117 m). Only 6 experienced severe constipation (3 ganglionic, 2 no biopsy, 1 aganglionic), all of whom responded to a bowel management program, and none developed other manifestations of HD (abdominal distension, failure to thrive or enterocolitis) or required additional surgery. CONCLUSIONS: Our results strongly suggest that the association of ARM and HD is extremely rare and the practice of searching for ganglia in the distal rectum or fistula of ARM patients should be discouraged to avoid potential misdiagnosis and overtreatment.

The Results of Pneumatic Balloon Dilatation Treatment in Children with Achalasia: A Single-Center Experience.

BACKGROUND/AIMS: Achalasia is a primary motility disorder characterized by a relaxation disorder of the lower esophageal sphincter. In pneumatic balloon dilatation, which is one of the treatment methods, the muscle fibers are torn with an endoscopically inflated balloon in the lower esophageal sphincter. This study aimed to evaluate the results of long-term pneumatic balloon dilatation treatment in our clinic for children diagnosed with achalasia. MATERIALS AND METHODS: Pediatric patients who underwent pneumatic balloon dilatation with a diagnosis of achalasia in our pediatric gastroenterology clinic between 2016 and 2021 were included in the study. Demographic data of the patients, clinical findings at diagnosis, and follow-up results were evaluated retrospectively. RESULTS: Ten patients who underwent 18 pneumatic balloon dilatation operations were included in the study. The mean follow-up period of the patients was 23.7 ± 14.1 months. It was observed that the procedure was performed once in 3 (30%) patients, twice in 2 (20%) patients, and 3 times in 3 (30%) patients. It is noteworthy that the diameter of the balloon used in the first procedure in patients who needed repeated operations was less than 30 mm. No complications were observed except for chest pain, which was detected in 1 patient. CONCLUSION: When the patients who needed recurrent dilatation were evaluated, it was noted that the diameter of the balloon in which the first procedure was performed in these patients was smaller. This study is an important contribution to the literature due to the scarcity of the pediatric achalasia data, in which long-term results related to pneumatic balloon dilatation are reported in Turkey.

Impact of Scoliosis Severity on Gastrostomy-Related Complications in Children.

OBJECTIVES: This study aimed to determine the relationship between scoliosis and risk of developing complications in patients who underwent gastrostomy. METHODS: Patients who underwent percutaneous endoscopic gastrostomy (PEG) or surgical gastrostomy (SG) between 2012 and 2022 were included. Leakage, discharge, granuloma, and hyperemia were considered minor complications, while visceral injury, ileus, and re-do surgery were considered major complications. The degree of scoliosis was calculated using the Cobb angle. The SG and PEG groups were compared by evaluating the complications and their correlation with scoliosis. RESULTS: A total of 104 patients with a mean age of 5.0 ± 5.3 were included; 58% of patients were treated with SG. Patients in the SG group were younger ( P < 0.001). Minor complications were significantly more common in the PEG group ( P = 0.018). There was no difference between the groups in terms of major complications ( P = 1.000). Scoliosis was observed in 32.7% of the patients (n = 34). In the SG group, no correlation was found between the Cobb angle and the frequency of minor ( P = 0.173) or major complications ( P = 0.305). There was no significant difference between the Cobb angles of patients with and without minor complications in the PEG group ( P = 0.478); the Cobb angles of patients with major complications (75°) were significantly higher than those without (36°) ( P = 0.030). CONCLUSION: Gastrostomy is important for weight gain and nutritional needs of children. This study showed that the risk of complications in SGs did not correlate with the degree of scoliosis and that the risk of major complications in PEGs increased in patients with a high degree of scoliosis.

Differentiating abdominal pain due to COVID-19 associated multisystem inflammatory syndrome from children with acute appendicitis: a score system.

PURPOSE: Differentiating abdominal pain due to coronavirus disease (COVID-19)-associated multisystem inflammatory syndrome (MIS-C) in children with acute appendicitis (AA) can cause diagnostic dilemmas. This study aimed to evaluate the efficacy of a previously described scoring system and improve its diagnostic ability in differentiating between these diseases. METHODS: This study was conducted between March 2020 and January 2022. Patients who had MIS-C with gastrointestinal system (GIS) involvement and patients who underwent surgery for appendicitis were included. First, all patients were evaluated using the new scoring system (NSS). The groups were compared by adding new MISC-specific parameters to NSS. The scoring system was evaluated using propensity score matching (PSM). RESULTS: A total of 35 patients with abdominal pain due to GIS involvement in MIS-C (group A) and 37 patients with AA who had ALT, PRC, and D-dimer results at their first admission (group B) were included in the study. The mean age of patients in group A was lower than that of patients in group B (p < 0.001). False NSS positivity was found in 45.7% of the patients with MIS-C. Lymphocyte (p = 0.021) and platelet counts (p = 0.036) were significantly lower in the blood count and serum D-dimer (p = 0.034), C-reactive protein (CRP) (p < 0.001), and procalcitonin (p < 0.001) were significantly higher in the MIS-C group. We created a scoring system called the Appendicitis-MISC Score (AMS) using the NSS and new parameters. The sensitivity and specificity of AMS diagnostic scores were 91.9% and 80%, respectively. CONCLUSION: MIS-C with GIS involvement may present as acute abdomen. It is difficult to differentiate this condition from acute appendicitis. AMS has been shown to be useful for this differentiation.

Hydatid Disease in Children from Diagnosis to Treatment: A 10-year Single Center Experience

Objective: Hydatid disease caused by Echinococcus granulosus is a parasitic zoonosis and is endemic in Turkey. Clinical manifestations vary and are related to the anatomical location. In this report, we shared the diagnosis, treatment and follow-up of hydatid disease in children with a 10-year experience. Methods: A total of fifty-seven children diagnosed with hydatid disease were analyzed retrospectively from hospital records. Diagnosis was based on clinical, serological and radiological findings. Treatment response was evaluated with clinical, radiological and serological findings. Results: The male/female ratio of 57 cases was 2.4:1 and the mean age was 113.6±45.9 months. The most common presenting complaint was abdominal pain (42.1%). While 22 (38.6%) of the cases had eosinophilia; indirect hemagglutination test positivity was detected in 27 cases (47.4%). Multiple organ involvement was present in 18 cases (31.6%). In patients with multiple organ involvement, the possibility of cysts being located in the abdomen was higher (p=0.005). Of the 50 cases (87.7%), 45 (78.9%) were operated with open surgery and 5 (8.8%) with percutaneous aspiration-injection-reaspiration method for treatment. There were 52 (91.2%) patients who were given albendazole in conservative treatment and the mean duration of treatment was 15.5±17.2 months. There were 10 cases (17.5%) who developed cyst rupture and the symptom duration was shorter than the cases without cyst rupture (p=0.017). Cyst rupture was more common in cases with dyspnea and fluid discharge from the mouth called rock water (p=0.001, p=0.005, respectively). Recurrence was observed in five cases (8.8%) during follow-up. Conclusion: In areas where the disease is endemic, despite prevention and control programs consisting of personal habits and health education, active transmission of hydatid disease is seen in children and continues to be an important public health problem. Hydatid disease should definitely be considered in the presence of suspicious radiological and clinical findings in endemic areas. Controlled clinical studies are required for diagnosis and treatment procedures.

Reassessment of a Decade of Experience on Testicular Torsion: Are We Making a Mistake?

INTRODUCTION: Testicular torsion is a serious surgical emergency of children. Prompt recognition and exclusion of other acute scrotal causes are essential for avoiding testicular loss. The aim of this study was to evaluate 10 years of experience with testicular torsion, point out our pitfalls in diagnosis and management, determine our likelihood of performing orchiectomy for potentially reversible injury. MATERIAL AND METHOD: Records of patients operated for testicular torsion in the last decade were reviewed retrospectively. Clinical findings, symptoms, type of surgery, accuracy of radiological evaluation, and the outcome were analyzed. Orchiectomy specimens were reevaluated and histologically graded to determine the existence of previously undetermined low-grade injury. RESULTS: In total, 107 children were operated for testicular torsion. Presentation included pain 96 (89.7%), scrotal swelling 48 (44.8%). Doppler ultrasonography was performed in 96 patients with false-negative results in 26 (27%). Testicular salvage occurred in 65 (60.7%) patients of which 6 (9.2%) developed subsequent testicular atrophy. Forty-two (33.9%) patients were treated with orchiectomy and histologic reevaluation, and grading of the specimens revealed 4 (9.7%) low-grade injury which indicates a potential of reversible injury. Seventeen (13.7%) patients had normal testicular anatomy in surgery. CONCLUSION: Surgical exploration is mandated in case of clinical suspicion for testicular torsion even with a normal flow Doppler ultrasound. Macroscopic evaluation does not always correlate with microscopic findings, and a decision according to it may result in excision of potentially viable testis. Further studies are required to determine the actual risk of contralateral autoimmune damage and increase the rate testicular salvageability after testicular torsion.

Irrigation of peritoneal cavity with cold atmospheric plasma treated solution effectively reduces microbial load in rat acute peritonitis model.

Accurate and timely diagnosis of appendicitis in children can be challenging, which leads to delayed admittance or misdiagnosis that may cause perforation. Surgical management involves the elimination of the focus (appendectomy) and the reduction of the contamination with peritoneal irrigation to prevent sepsis. However, the validity of conventional irrigation methods is being debated, and novel methods are needed. In the present study, the use of cold plasma treated saline solution as an intraperitoneal irrigation solution for the management of acute peritonitis was investigated. Chemical and in vitro microbiological assessments of the plasma-treated solution were performed to determine the appropriate plasma treatment time to be used in in-vivo experiments. To induce acute peritonitis in rats, the cecal ligation and perforation (CLP) model was used. Sixty rats were divided into six groups, namely, sham operation, plasma irrigation, CLP, dry cleaning after CLP, saline irrigation after CLP, and plasma-treated saline irrigation after CLP group. The total antioxidant and oxidant status, oxidative stress index, microbiological, and pathological evaluations were performed. Findings indicated that plasma-treated saline contains reactive species, and irrigation with plasma-treated saline can effectively inactivate intraperitoneal contamination and prevent sepsis with no short-term local and/or systemic toxicity.

Comparing the fecal continence scores of patients with anorectal malformation with anorectal manometric findings.

BACKGROUND: Patients undergoing surgery for anorectal malformation (ARM) may have defecation-related problems throughout their lives, even if they are perfect treated surgically. Assessment methods are needed to standardize the clinical outcomes of patients with ARM. The aim of this study was to compare the scoring systems (SS) with the anorectal manometry (AM) findings. METHODS: The data of patients operated on for ARM were examined. Holschneider's, Rintala's, Krickenbeck's and Peña's questionnaires were executed to the patients and AM was performed. RESULTS: Our study was completed with 23 patients. There was a statistically significant relationship between the anal resting pressure and Holschneider's questionnaire (HQ). There was a statistically significant relationship between the area under the curve in the maximum voluntary squeeze pressure-time graph (AUC) and the HQ and Rintala's questionnaire (RQ). A statistically significant difference was found between HQ and RQ scores and high type and low type of ARMs. CONCLUSION: In our study, based on AM data, it was found that the use of HQ and RQ from the four SS we compared could be more effective in patients' follow-up. It was concluded that Peña's questionnaire and Krickenbeck's questionnaire should be used to determine the bowel management program of the patients rather than patients' follow-up. LEVELS OF EVIDENCE: Level II.

The effect of probiotics on intestinal motility in an experimental short bowel model.

PURPOSE: To investigate the effect of probiotics on spontaneous contractions of smooth muscle isolated from jejunum and ileum of rat model. METHODS: Four rat groups were created (n=8, in each) including control (Group 1), control+probiotic (Group 2), short bowel (Group 3), and short bowel+probiotic (Group 4). Groups 1 and 2 underwent sham operation, Groups 3 and 4 underwent massive bowel resection. Bifidobacterium Lactis was administered in Groups 2 and 4 daily (P.O.) for three weeks. On postoperative week 3, rats were sacrificed, and jejunum and ileum smooth muscle were isolated for organ bath. Muscle contraction changes were analyzed before and after addition of antagonists. RESULTS: Short bowel group exhibited increased amplitude and frequency of spontaneous contractions. The addition of probiotics significantly decreased enhanced amplitude and frequency of bowel contraction in short bowel group and returned to control values. L-NNA increased amplitude and frequency of contractions in all groups. While indomethacin and nimesulide increased the amplitude in all groups, the frequency was only increased in jejunum. Hexamethonium and tetrodotoxin did not change the contraction characteristics in all groups. CONCLUSION: We suggest that early use of probiotics may significantly regulate bowel motility, and accordingly improve absorption of nutrients in short bowel syndrome.

Modified Leadbetter-Politano Ureteroneocystostomy: A Safer Procedure.

PURPOSE: Open surgical reimplantation of ureters is a highly successful procedure, with reported correction rates of 95 to 99 percent regardless of the severity of vesicoureteral reflux (VUR). Leadbetter-Politano ureteroneocystostomy is one of the most preffered technique for open ureteroneocystostomy.  The authors report the modified Politano-Leadbetter technique with extravesical mobilization and transection of the ureter at the level of ureterovesical junction and intravesical reimplantation. Materials and Methods: Fifty-seven children with unilateral VUR, underwent modified Leadbetter-Politano ureteral reimplantation with extravesical mobilization and transection of the ureter at the level of ureterovesical junction and intravesical reimplantation. Persistence of VUR despite endoscopic correction, breakthrough infections, complications due to antibiotics, progressive renal scarring, reflux nephropathy, and parental preference were indications for open reimplantation. Operations were done by two full-time pediatric surgeons. Operation time and hospital stay of the patients, reflux persistency, voiding dysfunction and complications were recorded.  Results: No ipsilateral VUR was detected postoperatively. Mean operation time was 76.54 min (±8.76 min; range, 70-86 min) Mean duration of the hospital stay is 82.31 h (±9.78 h; range, 71-93 h). Postoperative gross hematuria was not seen in any patients. No voiding dysfunction and no late complications was encountered.  Conclusions: Modified Leadbetter-Politano technique is a good option to treat VUR with success rate up to 100% without any major complicatons such as viscus perforation and ureteral obstruction. It is a rather simple technique that require less operative time.

Clinical features and treatment of ruptured pulmonary hydatid cyst in children.

Backgroud and objectives. Rupture is the main complication of the pulmonary hydatid cyst (HC). The aim of this study was to evaluate the clinical features and treatment of ruptured pulmonary HC. METHOD: The medical records of children who had undergone surgery between January 1999 and December 2017 for pulmonary HC were retrospectively evaluated. One hundred forty seven of these patients had ruptured HC at the time of diagnosis. The gender, age at the time of diagnosis, sociogeographic status (i.e., from urban or rural population group), symptoms, affected lung region, cyst dimensions, preoperative complications, medical treatment duration, and associated morbidities were evaluated. RESULTS: The study included 649 patients with pulmonary HC. Mean age was 9,8 (2-17) years. Three hundred forty four patients were male and 305 were female. The most common symptoms were, cough accompanying mucopurulent sputum, hydropthysis and dyspnea in patients with ruptured HC. The diagnosis of all the patients were established in the light of the findings obtained from two-sided chest x-ray and CT of the thorax. Simple cystotomy via posterolateral thoracotomy was the treatment of choice. Cappitonage was not performed in any patients. Lung resection was performed only if there was an irreversible and disseminated pulmonary destruction. CONCLUSION: Rupture of the pulmonary HC is the most common and also the most feared complication. Rupture may be either intrabronchial or intrapleural. Radiologic imaging is diagnostic. Rupture of the pulmonary HC must be considered as an emergent issue. Simple cystotomy amd removal of the laminated membranes are adequate treatment of choice. Meticulous closure of the bronchial openings is mandatory to avoid prolonged air leak. Cappitonage is unnecessary.

Diagnostic Value of Serum Urokinase-Type Plasminogen Activator Receptor in Children With Acute Appendicitis.

OBJECTIVES: Acute appendicitis (AA) is the most common surgical emergency in children. The accurate and timely diagnosis of AA in children can be challenging, and delayed diagnosis rates have been reported to range from 5.9% to 27.6%. Although combining clinical history and repeated physical examination with laboratory tests and radiographic imaging modalities help reach the diagnosis, novel biomarkers can support the surgeons' decision as well. The aims of this study were to evaluate a new plasma marker, urokinase-type plasminogen activator receptor (uPAR), to improve diagnostic accuracy in AA patients, and to determine a cutoff value of uPAR, which can safely include/exclude the diagnosis of AA. METHODS: We conducted a prospective study of children who underwent surgery for AA. Patients were categorized into the following 3 groups: group 1, controls consisted of 32 healthy volunteers; group 2, patients underwent surgery for nonperforated AA (n = 35); and group 3, patients underwent surgery for perforated AA (n = 21). Blood was sampled from group 1 at the admission and from group 2 and 3 before appendectomy. Serum uPAR, white blood cell count, absolute neutrophil count (ANC), and C-reactive protein concentrations were measured. RESULTS: Urokinase-type plasminogen activator receptor, ANC, and white blood cell count values were significantly higher in group 2 and 3 than group 1, but there was no significant difference between group 2 and 3. C-reactive protein values were significantly higher only in group 3 than other groups. The cutoff value for uPAR is 2.2 ng/mL with sensitivity of 85.7% and specificity of 84.3% and ANC is 5900 cells/mm with sensitivity of 91.1% and specificity of 96.9% to diagnose appendicitis. The specificity was 81.3% and sensitivity was raised to 98.2% when evaluated together. CONCLUSIONS: The incorporation of uPAR count and ANC could be a strong predictor of AA in children.

Hamartoma mesenquimal rabdomiomatoso en una ubicación inesperada / Rhabdomyomatous mesenchymal hamartoma developed at an unexpected location

El hamartoma mesenquimal rabdomiomatoso es una lesión cutánea rara descripta por primera vez en 1986 como "hamartoma de músculo estriado". En general, se presenta en la región de la cabeza y el cuello de los recién nacidos. En este artículo, describimos el caso de una niña de 38 días con un apéndice cutáneo congénito en la región perianal. En el examen físico, no se observaron anomalías congénitas ni otras lesiones cutáneas. En el examen histopatológico, se observó un hamartoma con fibras de músculo esquelético desorganizadas. El diagnóstico diferencial incluyó apéndice cutáneo, trago accesorio y fibroma péndulo. El hamartoma mesenquimal rabdomiomatoso se diferencia de las lesiones mencionadas debido al componente de músculo estriado. Dado que no conlleva el riesgo de recurrencia ni de transformación a neoplasia maligna, no es muy relevante diferenciarlo de estas lesiones. Sin embargo, es importante establecer el diagnóstico correcto porque aproximadamente un tercio de los casos se asocian con anomalías congénitas. Asimismo, es necesario un diagnóstico histopatológico en los niños con ubicación perianal debido a las manifestaciones clínicas similares al rabdomiosarcoma.

Rhabdomyomatous mesenchymal hamartoma is a rare dermal lesion which was first described in 1986 as "striated muscle hamartoma". It usually develops in the head and neck region of newborns. We report a 38-day-old girl with a congenital skin tag in the perianal region. Physical examination did not reveal any congenital abnormalities or other dermal lesions. Histopathological examination showed a hamartoma with disorganized skeletal muscle fibers. The differential diagnosis includes skin tag, accessory tragus and soft fibroma. Rhabdomyomatous mesenchymal hamartoma differs from the listed lesions with its striated muscle component. Since it does not carry the risk of recurrence and malignant transformation, it is not very important to distinguish it from these lesions. However, a correct diagnosis is important because approximately one third of the cases are associated with congenital anomalies. Also, histopathological diagnosis should be made in children with perianal localization due to similar clinical manifestation of rhabdomyosarcoma.

Case Report: Isolated Renal Hydatid Cyst in a Boy

Hydatic cyst is a crucial and prevalent parasitic disease in the developing countries in the Mediterranean region. Its diagnosis is sometimes problematic because of non-specific complaints and unavailability of any positive results in a routine laboratory analysis. Isolated renal hydatid cysts are very rare. In this study, a primary left renal hydatid cyst which was found in a 12-year-old boy was presented. He was referred by another hospital to our department with a flank pain and cystic mass in left kidney. Indirect haemagglutination test (IHA) for Echinococcus was negative. Nephrectomy was performed with the diagnosis of renal cyst hydatic. Renal cyst hydatid may present with various clinical findings ranging from asymptomatic clinical course to total loss in renal function. It will be beneficial to consider a renal hydatid cyst in patients with blurred flank pain, even if IHA is negative.

Secondary phimosis after circumcision.

OBJECTIVE: Male circumcision is one of the most common surgical procedures worldwide. Although it is widely performed because of health issues, in Muslim-majority countries, the primary motivation yielding to male circumcision is religious. It is a relatively safe procedure with a low overall complication rate. We herein report an underrated complication of circumcision that can be termed as "secondary phimosis." MATERIAL AND METHODS: The medical records of 25 boys with post-circumcision secondary phimosis were reviewed. Demographics of the patients, method of circumcision, type of provider, peroperative findings and comorbidities were recorded. RESULTS: Between January 2005 and December 2016, 25 boys with post-circumcision secondary phimosis were treated surgically. The median age of the patients was 3 (2-5) years. The majority of the patients were circumcised by the Gomco clamp or Plastibell method (n=16). Of the patients' circumcisions, six were performed by the freehand method, and three by the dorsal slit method. In 15 boys, circumcision was performed by a traditional provider. Of the boys, seven were circumcised by a physician, and three were circumcised by a pediatric surgeon. All the patients were re-circumcised. The common peroperative finding was the redundant mucosal inner layer of the prepucium. Excess suprapubic fat was present in 12 patients. CONCLUSION: Although circumcision is known as a minor surgical practice with low complication rate, it must be performed safely and especially by experienced physicians/surgeons. Secondary phimosis is a technical error that is caused by insufficient removal of the inner mucosal layer of the prepucium. Re-circumcision of the patient is inevitable, causing the patient second trauma.

Pentraxin-3: A strong novel biochemical marker for appendicitis in children.

INTRODUCTION: Appendicitis is the most common surgical disease evaluated by pediatric surgeons in the emergency department. Despite the history, physical examination, laboratory tests and imaging methods, the misdiagnosis may be observed often in children. Pentraxin-3 (PTX-3) is an acute phase protein which is produced directly in the inflammatory tissue. Our aim was to investigate the diagnostic value of PTX-3 levels in appendicitis in pediatric patients and compare it with the other serum parameters. METHODS: Eighty-eight patients (aged <18 years) were included in this study [Group 1 (n = 28) healthy volunteers, Group 2 (n = 28) patients with non-specific abdominal pain, Group 3 (n = 34) patients underwent appendectomy]. Serum white blood cell (WBC), absolute neutrophil count (ANC), neutrophil/lymphocyte ratio (NLR), C-reactive protein (CRP) and PTX-3 values were measured. RESULTS: Median serum levels of WBC were higher in Group 2 and 3 than Group 1. ANS, NLR, CRP and PTX-3 were higher in Group 2 than Group 1 and were higher in Group 3 than the other groups. The highest sensitivity was found in NLR >3.5 [94.1 (95% CI = 80.3-99.3)] and PTX-3 > 5.6 ng/mL [91.8 (95% CI = 76.3-98.1)]. PTX-3 has the highest specificity among all of the parameters [90.7 (95% CI = 79.7-96.9)]. The area under the ROC curve showed that the diagnostic value of PTX-3 was greater than any other parameter [0.979 (95% CI = 0.92-0.99)]. CONCLUSION: In this study, we have shown that PTX-3 is very useful with high sensitivity and specificity in the diagnosis of appendicitis compared to WBC, ANS, NLR and CRP as a first in the literature.

Assessment and outcome of pediatric intestinal pseudo-obstruction: A tertiary-care-center experience from Turkey.

BACKGROUND/AIMS: Pediatric intestinal pseudo-obstruction (PIPO) is a severe disorder of gut motility. In this rare and difficult-to-manage disease, complex treatment method, such as intestinal transplantation, is sometimes needed. This study evaluated the management and follow-up results of patients with PIPO who received treatment at our center. MATERIALS AND METHODS: The cases of 13 patients with PIPO were reviewed retrospectively. Demographic data, clinical features, etiologies, pharmacological and surgical treatments, nutritional support, anthropometric findings, small bowel transplantation (SBT), and survival rates were assessed. RESULTS: Two of the patients were diagnosed at 1 and 5 years of age, while other patients were diagnosed during neonatal period. The etiological cause could not be identified for 5 patients. Pharmacological treatment response was observed in 38.4% of patients. Post-pyloric feeding was applied in 4 patients, but no response was observed. Gastrostomy decreased the clinical symptoms in 3 patients during the abdominal distension period. Total oral nutrition was achieved in 38.4% of the total-parenteral-nutrition (TPN)-dependent patients. It was observed that anthropometric findings improved in patients with total oral nutrition. Liver cirrhosis developed in 1 patient. Venous thrombosis developed in 4 patients. The SBT was performed on 3 patients. One of these patients has been followed up for the last 4 years. CONCLUSION: Pediatric intestinal pseudo-obstruction is a rare disease that can present with a wide range of clinical symptoms. While some patients require intestinal transplantation, supportive care may be sufficient in others. For this reason, patients with PIPO should be managed individually.

Self-introduced intravesical magnets in a 3-year-old boy: Case report.

Özdemir T, Orhan G, Candan B, Köylüoglu G. Self-introduced intravesical magnets in a 3-year-old boy: Case report. Turk J Pediatr 2019; 61: 286-288. Self-introduced intravesical foreign bodies are commonly seen in adults and are rarely encountered in children. The underlying cause may be a psychiatric disorder for sexual gratification or inquisitiveness as in children. We herein report a 3-year-old boy who was presented with pathological lower urinary tract symptoms and a radiopaque, irregular shaped object in bladder detected by direct abdominal radiograph. Preoperative diagnosis was bladder calculus. Cystolithotomy was planned via Pfannenstiel approach. During operation, self-introduced small magnets and a metallic bead which stuck together were detected. Intravesical foreign bodies are important considerations in the differential diagnosis of pathological lower urinary tract symptoms. In this case, magnets that were stuck together and a metallic bead mimicked bladder calculus radiologically. However, irregular shape of the intravesical object may arouse a suspicion about the nature.

Effects of topical application of platelet-rich plasma on esophageal stricture and oxidative stress after caustic burn in rats: Is autologous treatment possible?

BACKGROUND: Caustic esophageal burn is still an important health problem in pediatric surgery. Although there are a number of experimental and clinical studies to increase the recovery of the esophagus and reduce the stenosis rate, there is no consensus on the treatment protocol. Platelet-rich plasma (PRP) is an autologous blood product, which has positive effects on wound healing, reepithelization and scar prevention. The aim of our study was to investigate the effects of PRP on stricture formation and oxidative status after caustic esophageal injury in rats. METHODS: Twenty-one rats were divided into three groups [Sham operation (n = 8), corrosive esophageal burn with 30% NaOH (n = 6), topical PRP application after corrosive burn (n = 7)]. On the postoperative 21st day, oxidative markers were measured in the serum, and collagen accumulation and stenosis index were measured histopathologically to assess the efficacy of PRP treatment. RESULTS: Postoperative weight was higher than preoperative weight in Sham and PRP groups, but lower in the Burn group (p < 0.05). No difference was observed between Sham and PRP groups at total antioxidant status and paraoxonase values, but a significant decrease was found in the Burn group. Group PRP had higher total oxidant status and arylesterase levels than Group Burn (p < 0.05). There was no difference in total thiol values between PRP and Sham group. Histopathological scoring for muscularis mucosa damage revealed a significant reduction in Group PRP, compared to Group Burn (p < 0.05). Esophageal wall thickness and SI were reduced, and luminal diameter was increased in Group PRP compared to Group Burn (p < 0.05). CONCLUSION: For the first time in the literature, these results indicate that topical PRP treatment after the experimental corrosive burn has a positive effect on oxidative stress, mucosal healing and decreased stricture development. PRP may be an alternative at the clinical treatment because it can be used during diagnostic esophagoscopy. TYPE OF STUDY: Treatment study Level I (randomized controlled trial).
