In-depth exploration of the radiation exposure to staff performing endoscopic retrograde cholangiopancreatography procedures (ERCP) through RANDO phantom and TLDs.

This study provides a comprehensive evaluation of the occupational radiation exposure faced by healthcare professionals during Endoscopic Retrograde Cholangiopancreatography (ERCP) procedures. Utilizing an anthropomorphic RANDO phantom equipped with Thermoluminescent Dosimeters (TLDs), we replicated ERCP scenarios to measure radiation doses received by medical staff. The study meticulously assessed radiation exposure in various corresponding body regions typically occupied by medical staff during ERCP, with a focus on eyes, thyroid, hands, and reproductive corresponding organ regions. The findings revealed significant variations in radiation doses across different body parts, highlighting areas of higher exposure and underscoring the need for improved protective measures and procedural adjustments. The effective radiation doses were calculated using standard protocols, considering the varying levels of protection offered by lead aprons and thyroid shields. The results demonstrate the substantial radiation exposure experienced by healthcare staff, particularly in regions not adequately shielded. This study emphasizes the necessity for enhanced radiation safety protocols in clinical settings, advocating for advanced protective equipment, training in radiation safety, and the exploration of alternative imaging modalities. The findings have crucial implications for both patient and staff safety, ensuring the continued efficacy and safety of ERCP and similar interventional procedures. This research contributes significantly to the field of occupational health and safety in interventional radiology, providing vital data for the development of safer medical practices.

The role of serum nesfatin-1 in a rat model of acute pancreatitis.

BACKGROUND: Acute pancreatitis (AP) is a disease that can still be fatal despite rapid advances in medicine. The relationship between serum nesfatin-1 levels and AP is still to be fully resolved. OBJECTIVES: To investigate the utility of serum nesfatin-1 levels in the diagnosis of AP. MATERIAL AND METHODS: Twenty-four male Sprague Dawley rats were divided into control, mild pancreatitis and severe pancreatitis groups (n = 8/group). Acute pancreatitis was induced by cerulein injection and the control group received saline injections. Then, the serum nesfatin-1, amylase, lipase, aspartate aminotransferase (AST), and alanine aminotransferase (ALT) levels were determined. A pathologist blinded to the study scored the severity of pancreatitis. RESULTS: There was a considerable decrease in serum nesfatin-1 levels in parallel to the severity of pancreatitis, though there was no statistically significant relationship observed between pancreatitis and nesfatin-1. In addition, there was no significant difference in AST or ALT levels among the groups. However, a strong positive correlation between amylase and lipase levels was observed (p < 0.05). The severe pancreatitis group (group 3) had a higher lipase level and pathology score than mild pancreatitis group (group 2), and this difference was statistically significant. CONCLUSIONS: Serum nesfatin-1 may be used as a diagnostic and severity marker in pancreatitis in the future.

Anogenital distance and anal position index in cadaveric human fetuses.

The aim of this study is to contribute to the determination of the normal values of human anogenital distance (AGD) and anal position index (API) in the antenatal period. 59 formalin-fixed human fetuses were examined. AGD was measured by the distance between the center of the anus and the posterior fourchette in females, and the distance between the center of the anus and the posterior scrotal raphe in males. API in female fetuses was determined with the formula API = fourchette-center of anus/fourchette-coccyx formula, and API = posterior scrotal raphe-center of anus/posterior scrotal raphe-coccyx in males. The mean AGDs of the female and male fetuses in the second trimester were 5.60 ± 1.60 mm and 9.64 ± 2.75 mm and 12.88 ± 4.14 mm and 17.26 ± 5.55 mm in the third trimester, respectively. The AGD values were found to be significantly higher in the males (p = 0.002). While the API values detected in the female and male fetuses were 0.43 ± 0.085 and 0.55 ± 0.072 in the second trimester, they were 0.46 ± 0.079 and 0.55 ± 0.058 in the third trimester. The API values were found to be significantly higher in the male fetuses (p < 0.001). When the distribution of API values of the fetuses in the second and third trimesters was examined, no significant difference was found (p = 0.499). In addition, no significant correlation was found between API and AGD values and percentile groups of fetuses (p Ëƒ 0.05). The AGD and API differed significantly between female and male fetuses starting from the antenatal second trimester, and the difference was preserved independently of the fetal percentile in the later stages of pregnancy.

Evaluation of gastroesophageal reflux in pediatric laparoscopic appendectomy procedures.

BACKGROUND: The increased intra-abdominal pressure during laparoscopic surgical procedures was reported to be a factor in the development of gastroesophageal reflux. This study evaluated the presence of gastroesophageal reflux and associated factors using 24-h pH monitoring in children undergoing laparoscopic appendectomy. METHODS: Children who underwent laparoscopic surgery for presumed acute appendicitis between June 2017 and June 2018 were included in the study. After pre-operative endotracheal intubation, pH catheters were placed for 24-h esophageal pH monitoring. Relationships between gastroesophageal reflux and procedure time, pre-operative fasting time, age, weight, and body mass index (BMI) were evaluated. RESULTS: A total of 60 pediatric patients were included in the study. Their mean (SD) age was 11.82 (3.71) years (range, 4-17 years). The mean (SD) body weight was 41.27 (16.72) kg (range, 15-90 kg) and the mean (SD) BMI were 17.96 (4.37). The mean pre-operative fasting time was 15.52 (12.1) h, while the mean operative time was 38.42 (17.96) min. Lower age and weight were significantly associated with the presence of post-operative gastroesophageal reflux (p<0.05). Mean procedure time, mean pre-operative fasting time, and BMI were not significantly associated with intra- or post-operative gastroesophageal reflux (p>0.05). CONCLUSION: The lack of a significant relationship between mean procedure time and gastroesophageal reflux suggests that the mean duration of the laparoscopic procedures performed in this study is safe in terms of gastroesophageal reflux. The results also indicate that young age and low weight should be considered risk factors for gastroesophageal reflux in pediatric patients undergoing laparoscopic appendectomy.

Cytokines the Etiology of Idiopathic Granulomatous Mastitis.

OBJECTIVE: To investigate the roles of cytokines in the etiopathogenesis of idiopathic granulomatous mastitis (IGM). DESIGN: Case-control study. PLACE AND DURATION OF STUDY: Istanbul Training and Research Hospital, Istanbul, Turkey, from September 2020 to January 2021. METHODOLOGY: Idiopathic Granulomatous Mastitis patients in active or remission who were admitted to the breast diseases outpatient clinic and healthy volunteers were included prospectively in the present study. The IL-1ß, IFN-α2, IFN-γ, TNF-α, MCP-1, IL-6, IL-8, IL-10, IL-12p (p70), IL-17A, IL-18, IL-23 and IL-33 values were measured with Flow Cytometry. The blood samples were taken before the treatment in the active IGM group. The ages, physical examination findings, menopausal and smoking conditions, and treatment methods were also evaluated. RESULTS: A total of 32 patients including 19 patients with active and 13 in remission, and 18 controls, were inducted making up a total of 50 subjects. The mean age was 37.18±7.15. The IL-1ß, TNF-α, IL-10, and IL-18 values were lower in patients with IGM than in the control group. Granulomatous Mastitis patients smoked more than the healthy participants. When the active patients, remission patients, and control group were evaluated together, no significant differences were detected in cytokine levels. CONCLUSION: The autoimmune and granulomatous reactions may not play a role in the etiopathogenesis of IGM because of the low levels of Th1 and Th17-related cytokines. However, some to baseline reference ranges were established. KEY WORDS: Idiopathic granulomatous mastitis, Cytokine, Autoimmunity, Smoking.

pH and specific gravity of corrosive agents as indicators in caustic injuries.

BACKGROUND: Video endoscopy, which remains the diagnostic gold standard after ingestion of a corrosive substance, is performed under general anesthesia in children, requires advanced technology, and is costly. Simple and accessible methods are therefore needed to determine the need for endoscopy. The aim of this study was to evaluate the role of the pH and specific gravity of ingested substance in determining endoscopy indications after corrosive ingestion. METHODS: This prospective study included pediatric patients who presented after ingesting a corrosive substance from June 2018 to June 2019. Relationships between the extent of damage detected by endoscopy and the patient's age, physical examination findings, and the pH and specific gravity of the causative substance were evaluated. RESULTS: The degree of damage detected on endoscopy was significantly milder for corrosive substances with a pH between 2 and 12 (P = 0.003). In addition, pH values between 2 and 12 were significantly more common among patients without physical examination findings (P = 0.029). Specific gravity less than 1,005 was associated with mild injury detected by video-endoscopy (P = 0.011). Patients in whom severe injury was detected by endoscopy had marked findings on physical examination (P < 0.001). There was no significant relationship between physical examination findings and the specific gravity of the substance involved (P = 0.087). CONCLUSIONS: The results of this study suggest that conservative treatment options can be used without performing endoscopy in patients who have no physical examination finding after corrosive ingestion and where the pH of the substances is between 2 and 12 and the specific gravity of the substances is less than 1,005.

The Potential Role of Model for End-Stage Liver Disease (MELD)-Sodium Score in Predicting the Severity of Acute Pancreatitis.

Background and aim Acute pancreatitis is a common inflammation of the pancreas which can be severe and even potentially mortal. High rates of mortality showed the importance of immediate identification of patients at high risk and led the clinicians to refer to various scoring systems. Our aim was to investigate a clinical predictive model using the Model for End-Stage Liver Disease-Sodium (MELD-sodium) scoring system, adapting it to acute pancreatitis patients referring to the systemic inflammatory nature of the disease and potential multi-organ failures in severe form. Methods Our multicenter study was designed retrospectively. The medical records were reviewed for the period of two years. Demographics, biochemical results, MELD-sodium scores and mortality rates were analysed. Results MELD-sodium score was found to be statistically correlated with both mortality and the severity of pancreatitis (p<0.001) and significant difference between both mild and severe (p<0.001), moderate and severe groups (p<0.001). Mortality was found to be significantly higher in patients with MELD-Na score when the cut-off value was accepted as '≥11'. Conclusion We found that MELD-sodium score was significantly associated with both severity of disease and mortality rates and also significantly effective between both mild/severe and moderate/severe groups which may be a guide for future multi-center reviews with larger patient and control groups, which can define the potential role of this non-invasive and easy-to-use predictive model in acute pancreatitis patients.

Are the cytokines and chemokines important for the early diagnosis of mesenteric ischemia?

BACKGROUND: Acute mesenteric ischemia (AMI) has very high mortality and morbidity rates, and the most important factor in the prognosis of AMI is the duration of ischemia. This study aims to evaluate the changes of these markers according to the ischemia duration and possible use of cytokines and chemokines in the early diagnosis of AMI. METHODS: Twenty-one male Sprague-Dawley rats were divided into three equal groups. The Superior Mesenteric Artery and Superior Mesenteric Vein were tied tightly and exposed to ischemia for 2 h for Group 1 and 6 h for Group 2. There was no intervention for Group 3, and it was selected as a control group. Intracardiac blood samples were collected after 2 h in Group 1 and 6 h in Groups 2 and 3. The IL-1α, 1ß, 6, 10, 12p70, 17A, 18, 33, CXCL1/KC, CCL2/MCP-1, GM-CSF, IFN-γ, and TNF-α were measured using flow cytometry. RESULTS: Significant differences were observed between the groups in IFN-γ, CXCL1, MCP1, TNF-α, and IL-6 parameters. In the correlation analyses performed according to the mesenteric ischemia time, a very strong correlation was observed in CXCL1, as well as a strong level for MCP-1, TNF-α, and IL-6. Furthermore, a moderate level of correlation was found in IFN-γ, IL-10, and IL-18. CONCLUSION: The increased levels of CXCL1, MCP-1, TNF-α, and IL-6, which had a high correlation with the duration of ischemia in patients with intestinal ischemia, may help clinicians with diagnoses and treatment decision-making.

Giant composite pheochromocytoma and gastrointestinal stromal tumor in a patient with neurofibromatosis: A case report.

A 54-year-old male was admitted to our department with neurofibromatosis and hypertension. During his examination, a mass was detected in the abdomen, and he was transferred to a surgical clinic. At the first examination of the patient, extensive café-au-lait spots and granulomas were detected on the body and the mass occupying right abdomen quadrant was palpable. The patient's medical history indicated that he had hypertension for almost a decade. The patient also stated that nodules on the body existed from his earliest recollection and he had relatives with neurofibromatosis. The patient was taken to a surgical operation. A mass with 30×23 cm in size was removed. The area of the nodular structure, with 0.5 cm in diameter, in the stomach serosa was also removed. The tumor was composed of phaeochromocytoma in the larger spaces and ganglioneuromas in the relatively narrow spaces. The nodular area removed in gastric serosa was reported as a very low-risk gastrointestinal stromal tumor. Apart from this rare combination, adrenal mass removed from the patient was considerably larger than the masses in the literature until now. Therefore, we aimed to present this rare case with a literature background.

Evaluation of Gastroesophageal Reflux in Children as a Risk for Post-operative Nausea and Vomiting: An Observational Study.

1Background: Anaesthesia is known to reduce gastric emptying and motility, which can cause gastroesophageal reflux (GER) in some patients. Monitoring pH is a reliable method for detecting reflux. In this study, we aimed to show whether GER is a risk factor for post-operative nausea and vomiting (PONV) with oesophageal reflux measures in paediatric patients undergoing laparoscopic appendectomy. METHODS: After obtaining approval from ethics committee, 55 paediatric patients were included. An oesophageal pH metre catheter was inserted through the nasal passage to 3 cm above the lower oesophageal sphincter. pH measurements were evaluated with DeMeester score. It was accepted as acid reflux if the score was >14.7. The patients' demographic data, history of GER and verbal descriptive scale (VDS) to assess PONV and pH values were analysed with Statistical Package for the Social Sciences (SPSS) version 21 (IBM SPSS Corp.; Armonk, NY, USA). RESULTS: Of the 55 patients, 41.8% were girls, 58.2% were boys, the mean age was 13.2 years, the mean fasting period was 7.47 hours and the mean operation time was 1.1 hours. Mean fasting and operation times did not differ statistically according to VDS. There was no significant association between VDS group and gender or pH. None of the patients had a history of GER. Thirteen patients had DeMeester score >14.7. CONCLUSION: This is the first study about the relationship between gastric pH and PONV in paediatric patients. Although some studies have shown an association between anaesthesia and reflux, we detected reflux in nine of our patients and reflux was not statistically associated with PONV in our study. Further studies with larger patient groups are needed to provide a clearer opinion.

May Nesfatin-1 be a Biomarker in Acute Mesenteric Ischemia?

OBJECTIVE: To investigate the diagnostic value of nesfatin-1 in cases of intestinal ischemia and ischemia/reperfusion. STUDY DESIGN: An experimental study. PLACE AND DURATION OF STUDY: The Experimental Animals Laboratory of Bezmialem University, in June 2018. METHODOLOGY: Twenty-one healthy male Sprague Dawley rats were randomly divided into three groups of 7 rats each. In group 1: 1-hour intestinal ischemia followed by 5-hour reperfusion was performed. In group 2: rats were subjected to 6-hour intestinal ischemia. In group 3: rats underwent laparotomy and closure without performing any further procedure. Changes in leukocyte count, amylase, blood sugar, LDH, SGOT, CRP, and nesfatin-1 levels were determined. For histopathological examination, a small intestinal sample was taken and preserved in 10% formaldehyde. RESULTS: Nesfatin-1 value in group 2 was significantly higher than that in group 1 and group 3 (p=0.005, and p <0.001 respectively). Nesfatin-1 value in group 1 was significantly higher than that in group 3. A significant (r = 0.864/p <0.001) positive correlation was observed between nesfatin-1 value and pathology score. The pathology score of group 2 was significantly higher than that of group 1 and group 3 (p <0.001). CONCLUSION: Serum nesfatin-1 can be a biomarker in acute mesenteric ischemia.

Analyzing the effect of laparoscopy duration time on peroperative gastroesophageal reflux

Background/aim: Intraabdominal pressure (IAP) is one of the main reasons for gastroesophageal reflux (GER). This study investigates whether IAP during laparoscopic surgery leads to GER in a time-dependent manner. Materials and methods: In a laparoscopy model, 15 mmHg IAP was created in 8 Wistar albino rats in the Trendelenburg position (TP). A 5 mm laparotomy was performed in the left lower abdominal region, and a 6 Fr catheter was placed intraabdominally. Air was insufflated into the abdominal cavity, and the pressure was kept constant at 15 mmHg. Esophageal pH alterations were measured by pH sticks for 4 h every 30 min. Results: The basal median esophageal pH value was 9 (8­10), the value after placing the catheter was 9 (7­10) (P = 0.47), and the median pH value after placing the subjects in TP was 9 (8­10) (P = 0.70). In our experimental model, esophageal pH values were found to decrease significantly at the 150th minute in TP and at 15 mmHg IAP (P < 0.05). Two rats died: one at the 120th minute and the other at the 240th minute (P > 0.05) Conclusion: Esophageal pH values decreased and continued to remain low following IAP increase and TP in this experimental rat model. Prolonged laparoscopic procedures can particularly lead to GER that requires instant recognition and rapid and appropriate intervention.

Morgagni's Hernia: Analysis of 21 Patients with Our Clinical Experience in Diagnosis and Treatment.

A Morgagni's hernia is a congenital defect found in the anterior aspect of the diaphragm between the costal and the sternal portions of this muscle. This defect is also referred to as the space of Larrey. It has been reported that 70% of patients with Morgagni's hernia are female, 90% of the hernias are right-sided, and 92% of the hernias have hernia sacs. This type of hernia is a rare clinical entity and accounts for 3% of all surgically treated diaphragmatic hernias. There are no large retrospective or prospective studies on this topic. This type of hernia is a rare type among adults without a well-described prevalence and without well-established definitive management strategies. There are also few clinical reports about this clinical entity and its surgical treatment. We treated 21 patients with Morgagni's hernia in a 12-year period, and we report our experience while discussing the surgical treatment of this disease. We performed a retrospective review of the 21 patients who were operated between 2003 and 2015. These patients had undergone surgical repair of Morgagni's hernia. For each subject, demographic data, symptoms of presentation, physical examination findings, preoperative imaging studies and diagnosis, and surgical procedures were documented. Location of the hernia sac and its contents, postoperative complications, and duration of hospital stay were recorded and evaluated. Twelve patients were females and nine were males. The mean age of patients was 63.85 years. Dyspnea was the most prominent symptom in our patients. Morgagni's hernias were located on the right side in 19 patients and on the left side in 2 patients. Chest X-ray in 10 patients and abdominal computerized tomography in 17 patients were the major diagnostic tools. Four patients were operated as emergency while others underwent elective surgery (17 patients). Twelve patients were operated with laparoscopy and the remaining nine were operated with the conventional open abdominal technique. Hernia sacs were observed in all of the patients and removed except in four of them. The omentum and the transverse colon were the most commonly seen organs in hernia sacs. Hernia defects were repaired with primary sutures in four patients (all open cases) and primary closure supported with mesh in six patients (four laparoscopic, two open cases). In the remaining 11 patients, hernia defects were closed with synthetic meshes (eight laparoscopic, three open cases). Mean postoperative hospital stay was 9.8 days. No recurrence was observed in any patients. Only one of our patients died during follow-up. In Morgagni's hernias, surgical intervention is necessary as the hernia may cause complications such as strangulation of the colon or intestines. A laparoscopic approach has increased its popularity in recent years because of the well-known advantages of laparoscopy.

The impact of surgical intervention on renal function in cystinuria.

INTRODUCTION: Cystinuria is an autosomal recessive disorder due to intestinal and renal transport defects in cystine and dibasic amino acids, which result in recurrent urolithiasis and surgical interventions. This study aimed to assess the impact of surgical interventions on renal function by analyzing estimated glomerular filtration rates. METHODS: Thirteen pediatric patients with cystinuria, who were followed-up in a single tertiary institution between 2004 and 2016, were included in the study. Medical records were reviewed to collect data on clinical presentation of patients, urine parameters, stone formation, medical treatment, surgical intervention, stone recurrence after surgical procedure, stone analysis, ultrasonography, 99m-technetium dimercaptosuccinic acid (99mTc-DMSA) radionuclide imaging results, and follow-up time. Creatinine clearances estimated by modified Schwartz (eGFR) formula before and after surgery were used to assess renal function and compared statistically. RESULTS: Nine patients (69.2%) had renal scarring which were detected with 99mTc-DMSA radionuclide imaging. In ten patients (76.9%), open surgical intervention for stones were needed during follow-up. Significant difference was not detected between eGFR before and after surgical intervention (mean 92 versus 106, p = 0.36). Nine of the patients (69.2%) were stone free in the last ultrasonographic examination. Relapses of stone after surgery were seen in 66.6% of patients who underwent surgical intervention. CONCLUSIONS: Surgical interventions for urinary stones are commonly required in patients with cystinuria. Renal scarring is a prevalent finding in cystinuric patients. Surgical interventions have no negative impact on eGFR in patients with cystinuria according to the present study.

Hybrid appendectomy with classic trocar on McBurney's point.

INTRODUCTION: Appendectomy is still the most commonly performed intra-abdominal operation worldwide. Interestingly, it has not reached the same popularity as other laparoscopic surgical procedures. Although multiple techniques have been described, a standard approach has not been described for the laparoscopic technique yet. AIM: To perform hybrid appendectomy for acute appendicitis on McBurney's point, aiming to perform an easier and quicker procedure while limiting the trauma to the abdominal wall by obtaining the advantages of both laparoscopic and open techniques. MATERIAL AND METHODS: We retrospectively evaluated the results of 24 patients on whom we had performed hybrid appendectomy with an optical trocar on McBurney's point for acute appendicitis in 1 year in terms of demographics, operative time, complications, hospital stay and cosmetic results. RESULTS: Twenty-one of the patients underwent hybrid appendectomy with a one-optic trocar on McBurney's point. The mean operative time was 21.4 ±6.2 min. We did not encounter any postoperative complications in any of the patients. The median hospital stay was 1.2 ±1.0 days. The postoperative scar was minimal. CONCLUSIONS: This technique is defined in the literature for the first time, and it is easy and feasible for the surgeons. It may reduce the operative time and costs when compared to the conventional laparoscopic technique, but prospective studies with more patients are needed for more certain results.

Effective predictors for surgical decision in antenatal hydronephrosis: a prospective multiparameter analysis.

OBJECTIVE: The majority of antenatal hydronephrosis disappears spontaneously. In our study, we have investigated the effective predictors for surgical decision in antenatal hydronephrosis. MATERIAL AND METHODS: Forty-four patients found to have renal pelvic anteroposterior (AP) diameter more than 10-mm on antenatal ultrasonograpy were followed after birth. The study groups were divided into two groups: follow-up and surgery group. On follow-up, longitudinal diameter of the kidney, parenchymal thickness of the kidney, AP diameter of renal pelvis, AP diameter of middle calyces on ultrasonograpy, and differential renal function, 20th minute clearance, half-life of radionuclide tracer (T1/2), Tmax, Tmax-T1/2, normalised residual activity (NORA) on diuretic renography were evaluated. Ultrasonograpy and diuretic renography measurements were compared in patients whose hydronephrosis resolve or proceeded to surgery. RESULTS: Forty-four patients were diagnosed as antenatal hydronephrosis, spontaneous resolution occurred in 23 (52%), and surgery was performed in 21 patients (48%). Mean age at operation was 8.5±6.5 months (3-24 months). Mean AP diameter of renal pelvis was 29.5±14.2 mm for surgery group, 13.6±4.2 mm for follow-up group (p<0.001). Univariate analyses showed significance for all ultrasonographic measurements and only the differential renal function by diuretic renography. Multivariate logistic regression analysis showed significance for AP diameter of renal pelvis (odds ratio 1.37; 95% Cl 1.13-1.66), and differential renal function (odds ratio 1.14; 95% Cl 1.01-1.29). CONCLUSION: AP diameter of renal pelvis and differential renal function were the most effective parameters for surgical decision. These parameters can be used for appropriate management of antenatal hydronephrosis.

Laparoscopic management and its outcomes in cases with nonpalpable testis.

OBJECTIVE: Diagnostic laparoscopy is the gold standard in the algorithm of nonpalpable testis. Testicular tissue is examined and treatment is planned accordingly. In this study we reviewed the place of diagnostic laparoscopy, and evaluated the results and effectiveness of laparoscopy in the diagnosis and management of nonpalpable testis. MATERIAL AND METHODS: Children who had diagnostic laparoscopy for nonpalpable testes were included in the study. Physical examination results, ultrasonography (USG) reports, age at surgery, laparoscopic and inguinal exploration findings, surgical procedures, orchiopexy results, early and late-term complications were evaluated. Follow-up visits were performed at 3-month intervals for the first, at 6-month intervals for the 2. year, then at yearly intervals. Testicular size and location was evaluated by during control examination. RESULTS: Overall 58 boys, and 68 testes (26 left: 44.8%; 22 right: 37.9%, and 10 bilateral: 17.2%) were included in the study. Mean age at surgery was 5.5 years (10 months-17 years). Diagnostic value of USG was 15.7%. Diagnostic laparoscopy findings were as follows: Group 1: blind-ended vessels, n=7 (10.2%); Group 2: intraabdominal testes, n=8 (11.7%); Group 3: vas and vessels entering internal ring, n=53 (77.9%). Overall 43 testes underwent orchiopexy, which were normal (n=8) or hypoplastic (n=35). Mean follow-up period was 19 months (1-12 years), and on an average 7 visits were performed (5-14). On follow-up, 5 testes were normal-sized and located in the scrotum, while 4 testes were atrophic and underwent orchiectomy. Two testes were found in the inguinal canal and redo orchiopexy was performed. Control USG revealed reduced testicular blood supply and volume. CONCLUSION: Laparoscopic surgery is safe and effective in the management of nonpalpable testes. In the majority, routine use of diagnostic laparoscopy in the algorithma does not confer any additional contributions in many patients.

Rare Endobronchial Inflammatory Myofibroblastic Tumor in Pediatric Patient Detected on PET/CT Imaging.

Inflammatory myofibroblastic tumor (IMT) can be seen in all age groups, although it is more common in children and adolescents. We report the FDG PET/CT findings in an 8-year-old boy with endobronchial IMT. Endobronchial IMT is more commonly seen in young adults.

Laparoscopic one-stage Fowler-Stephens orchiopexy preserving gubernaculum.

OBJECTIVE: To assess gubernaculum-sparing laparoscopic one-stage Fowler-Stephens orchiopexy (FSO), in the management of high intrapelvic testis. MATERIAL AND METHODS: Medical reports of boys who underwent laparoscopic one-stage FSO were retrospectively reviewed. High intrapelvic testis was defined as testis ≥3 cm away from ipsilateral internal ring. Testes were evaluated on physical examination at 3rd, 6th and 18th months after surgery. Children were evaluated as for their demographic data, operative findings, interventional details and outcomes. RESULTS: Seven patients met inclusion criteria of the study. Six of 7 testis were small and had abnormal appearance, compared with the contralateral testis. Average distance of the testes from the internal ring was 4.2±1.1 cm (3 to 6). Average age at surgery was 6.1±4.2 years (2 to 12). Average follow-up period was 14±5.8 months (8 to 20), and 5 testis (71.4%) were considered to be normal in volume and scrotal location. Two testes were relatively atrophic and underwent orchiectomy. CONCLUSION: Our preliminary results shows a good testicular survival rate for one-stage laparoscopic FSO. Sparing collateral vasculature of the gubernaculum is important.

Effectiveness of endoscopic balloon dilatation in grade 2a and 2b esophageal burns in children.

PURPOSE: To evaluate the predictability of the initial endoscopic evaluation of the effectiveness of endoscopic balloon dilatation (EBD) in childhood esophageal strictures caused by corrosive ingestion. MATERIAL AND METHODS: Medical records of 635 endoscopies caused by corrosive ingestion between January 2000 and December 2015 in children between the ages of 0 and 18 years were retrospectively analyzed. Among them, five children with grade 2a and 15 with grade 2 b who developed esophageal strictures were evaluated for the effectiveness of endoscopic balloon dilatation. RESULTS: The stricture rate was 5/136 (3.6%) in grade 2a and 17/25 (68%) in grade 2 b esophageal burns. Strictures with grade 2a burn had seven (1-10) EBD sessions, and grade 2 b had 8.8 (1-30) EBD sessions. For grade 2a burns, the treatment period was 15 months and 18.8 months for grade 2 b burns. Three patients with grade 2 b and two patients with grade 2a are still on the EBD program. CONCLUSION: Initial endoscopy for caustic ingestion and esophageal injury grading may help to provide healthcare givers with information about future stricture formation and management.
