The aim was to explore factors associated with intestinal tissue levels of anti-TNF alpha (anti-TNF), anti-TNF antibodies, and cytokines in pediatric patients with Crohn Disease (CD). In a prospective exploratory study of CD patients undergoing ileocecal resection or colonoscopy between 6/2020 and 1/2023, we analysed tissue levels of anti-TNF, anti-TNF antibodies, and cytokines (TNF-α, IL-17, IL-1β, IFN-γ) from intestinal biopsies. Mixed-effects regression models, adjusted for potential confounders, were used. Data from 27 CD patients (18 females, 66.7%) were analysed. Fourteen (52%) received adalimumab (ADA) and thirteen received infliximab (IFX), with a median therapy duration of 17 (IQR 4.5-41.5) months. Higher levels of free anti-TNF were found in macroscopically inflamed tissue compared to non-inflamed tissue (β = 3.42, 95% CI 1.05-6.10). No significant association was found between serum and tissue anti-TNF levels (β= -0.06, 95% CI - 0.70-0.58). Patients treated longer with anti-TNF had increased IL-17 levels (β = 0.19, 95% CI 0.05-0.33), independent of disease duration and age. IFN-γ levels were linked with both follow-up duration and anti-TNF length. Our study shows significantly higher free drug levels in inflamed tissue. Long-term anti-TNF treatment has been linked to increased IL-17 levels, suggesting a possible impact on the cytokine response pathway. We did not observe a relationship between serum and tissue anti-TNF levels.

INTRODUCTION: Postoperative constipation (PC) in patients with imperforate anus and perineal fistula (PF) has been reported in up to 60%. Histological studies of PF revealed innervation anomalies which seem to be one of the reasons for PC. Perioperative histologically controlled fistula resection (PHCFR) allows appropriate resection of PF and pull-down normoganglionic rectum at the time of posterior sagittal anorectoplasty (PSARP). MATERIALS AND METHODS: A total of 665 patients with anorectal malformations underwent surgery between 1991 and 2021. Of these, 364 presented PF; 92 out of them (41 F) were studied. Patients with sacral and spinal cord anomalies, neurological disorders, and cut-back anoplasty were excluded. PSARP was done on all patients. Hematoxylin-eosin staining and NADH Tetrazolium-reductase histochemical method were used. Four and more ganglion cells in the myenteric plexus represented a sufficient length of the resection. The continence was scored according to the modified Krickenbeck scoring system. Final scores ranged from 1 to 7 points. Values are given as median. RESULTS: A total of 65 (70.7%) patients presented an aganglionic segment in PF, and 27 patients presented hypoganglionosis. The median length of the resected fistula was 25 mm (interquartile range [IQR]: 20-30). The median total continence score was 7 (IQR: 6-7). Post-op constipation was observed in 6/92 (6.5%) patients. CONCLUSION: PHCFR diminished PC to 6.5% of patients.

PURPOSE: Children diagnosed with Crohn's disease (CD) often undergo ileocecal resection (ICR) during childhood. Anastomotic recurrence is a frequent finding following this procedure. Data addressing the effect of the anastomosis type on disease recurrence are scarce in the pediatric population. The Kono-S anastomosis has shown promise in reducing endoscopic, clinical, and surgical recurrence rates in adults. We aimed to report our experience with Kono-S anastomosis in children, focusing on its feasibility and postoperative complications. METHODS: We retrospectively analyzed pediatric CD patients who underwent ICR with Kono-S anastomosis between August 2022 and May 2023. Data on demographics, clinical characteristics, surgery, hospitalization, and follow-up including colonoscopy were collected. Complications were classified using the Clavien-Dindo classification. RESULTS: Twelve patients (7 females, 58.3%) were included. Six (50%) of the patients had the B3 luminal form of the disease (according to Paris classification). Median surgery duration was 174 (interquartile range [IQR] 161-216) minutes. Anastomosis creation took a median of 62 (IQR, 54.5-71) minutes. Median hospitalization length was 6 (IQR 4-7) days. No short- or mid-term complications were observed. Median follow-up duration was 9.5 (IQR 6.8-12) months. CONCLUSION: According to our results, Kono-S anastomosis is safe and feasible in pediatric CD patients, with no observed postoperative complications. These findings support the potential benefit of using Kono-S anastomosis as a treatment approach in children with CD.

BACKGROUND: In recent decades, magnetic resonance imaging (MRI) has gained prominence as a standard diagnostic method for preoperative assessment in patients with anorectal malformations and a colostomy, with the potential to replace the classic fluoroscopic distal pressure colostogram (FDPC). Three MRI techniques are available: MRI-distal pressure colostogram with gadolinium (MRI-DPCG) or saline (MRI-DPCS) instillation into the colostomy and native MRI without colostomy instillation. OBJECTIVE: To evaluate and compare the diagnostic accuracy of MRI (native MRI, MRI-DPCG and MRI-DPCS) in the preoperative workup of boys with an anorectal malformation and a colostomy and to compare it to FDPC. MATERIALS AND METHODS: Sixty-two boys with preoperative MRI using one of the three approaches and 43 with FDPC met the inclusion criteria for this retrospective study. The presence and localization of rectal fistulas according to the Krickenbeck classification were evaluated and compared with intraoperative findings. RESULTS: The accuracy of fistula detection for MRI in general (regardless of the technique), MRI-DPCS, MRI-DPCG, native MRI and FDPC was 95% (59/62, P<0.001), 100% (12/12, P=0.03), 100% (30/30, P<0.001), 85% (17/20, P=0.41) and 72% (31/43, P=0.82), respectively. The accuracy of describing fistula type in patients with a correctly detected fistula using these methods was 96% (45/47, P<0.001), 100% (9/9, P<0.001), 100% (23/23, P<0.001), 87% (13/15, P<0.001) and 67% (13/21, P=0.002), respectively. CONCLUSION: MRI is a reliable method for detecting and classifying fistulas in boys with an anorectal malformation and a colostomy and can be considered the modality of first choice for preoperative workup.

AIM: Detection of possible predictive factors of endoscopic recurrence after ileocecal resection in Crohn's disease could be very beneficial for the individual adjustment of postoperative therapy. The aim of this study was to verify, whether immunohistochemical detection of calprotectin in resection margins is useful in diagnostics of endoscopic recurrence. METHODS: In this study we included pediatric patients with Crohn's disease who underwent ileocecal resection, regardless of pre-operative or post-operative therapy (n=48). We collected laboratory, clinical, surgical, endoscopic and histopathological data at the time of surgery and at 6 months after surgery. The immunohistochemical staining of calprotectin antigen was performed on all paraffin blocks from the resection margins. RESULTS: Out of 48 patients 52% had endoscopic recurrence in the anastomosis (defined by Rutgeerts score) within 6 months after surgery. The number of cells positive for calprotectin in the proximal resection margin was negatively associated with recurrence (P=0.008), as was the elevated level of total calprotectin (from both resection margins). There was no correlation of calprotectin in distal resection margin and endoscopic recurrence. Fecal calprotectin over 100 ug/g (P=0.0005) and high CRP (P<0.001) at 6 months after ileocecal resection and peritonitis (P=0.048) were associated with endoscopic recurrence. CONCLUSION: Approximately half of the patients developed endoscopic recurrence within 6 months after ileocecal resection. The predictive value of tissue calprotectin is questionable, as it is negatively associated with endoscopic recurrence. There are other potentially useful predictors, such as CRP and fecal calprotectin at 6 months after resection and the presence of peritonitis.

OBJECTIVE: To investigate sexual function and subjective attitudes towards surgery in adult women after feminizing genitoplasty (FG) for congenital adrenal hyperplasia (CAH). MATERIALS AND METHODS: We retrospectively reviewed the medical files of patients who underwent FG from 1996 to 2018. Of those, patients older than 16 years of age were asked to answer non-standardized questions aiming at the awareness of genital surgery and standardized questionnaire evaluating sexual function (GRISS). The anonymized answers were compared to a control group of 50 healthy females. Student's t-test, Pearson's χ2 test, Fisher's exact test and Spearman's rank correlation coefficient were performed. A P-value less than 0.05 was considered significant. RESULTS: Out of 106 patients who underwent FG, 64 were included, 55 successfully contacted and 32, aged 17-40 years (median 25.5), answered the questionnaires (58% response rate). In all, 11 patients underwent historical clitorectomy in early childhood by a pediatric gynecologist before 1996 and pull-through vaginoplasty at puberty. A total of 21 patients underwent modern one- or two-staged FG. There were statistically significant differences between the CAH group and controls as to the proportion living in committed partnerships (28% and 84%, respectively; p = 0.0000), having sexual intercourse (41% and 92%, respectively; p = 0.0000) and having their own children (13% and 36%, respectively; p = 0.0369). The median overall GRISS score was 4 (range 1-7) in the CAH group compared to 1 (range 1-9) in the control group, with infrequency and vaginismus representing the least favorable subscales (median 5). In all, 81% of the women operated on for CAH would recommend such an operation to any other individual with CAH and 66% of them suggested the surgery should be performed in early childhood. DISCUSSION: By this study we have contributed to the debate over suggestions that FG may cause adverse effects on sexual life of the patients in adulthood, beside already published effects on their mental well-being and LUTS. Despite possible selection bias due to only 58% response rate the comparison with control group shows only a moderate sexual dysfunction and more significant impact on long-term partnership that might be caused by other factors related to CAH beside FG itself. CONCLUSIONS: Partnership, offspring, sexual frequency and function were impaired in adult females with CAH after FG. However, the median GRISS score was below the pathological level of 5.

PURPOSE: We investigated quality of life, long-term lower urinary tract symptoms, sexual function and subjective attitudes toward surgery in adult women after feminizing genitoplasty for congenital adrenal hyperplasia. MATERIALS AND METHODS: We retrospectively reviewed the medical files of all patients with congenital adrenal hyperplasia who underwent feminizing genitoplasty from 1996 to 2018 in our tertiary center. Of those, patients older than 16 years of age were asked to answer 1 nonvalidated and 3 standardized and validated questionnaires evaluating their current mental well-being (WHO-5 Well-Being Index), lower urinary tract symptoms (ICIQ-FLUTS) and sexual function (GRISS). The anonymized answers of this cross-sectional study were compared to a control group of 50 healthy females. Student's t-test, Pearson's χ2 test, Fisher's exact test and Spearman's rank correlation coefficient were performed. A p-value less than 0.05 was considered significant. RESULTS: Out of 106 patients who underwent feminizing genitoplasty, 64 patients were included and 32 patients, aged 17 to 40 years (median 25.5 years), answered the questionnaires (50% response rate). The difference between congenital adrenal hyperplasia and control group mental well-being was not statistically significant (WHO-5 median score 60 and 64, respectively; p=0.82). We found no significant difference in the lower urinary tract symptoms subscales of filling, voiding or incontinence, nor in the overall lower urinary tract symptoms score (ICIQ-FLUTS overall median score 3.5 and 3, respectively; p=0.43). CONCLUSIONS: We found in our group no abnormal mental well-being or prevalence of long-term symptoms of lower urinary tract dysfunction in adult female patients with congenital adrenal hyperplasia following feminizing genitoplasty.

INTRODUCTION: The incidence of Crohn's disease (CD) within the pediatric population is increasing worldwide. Despite a growing number of these patients receiving anti-tumor necrosis factor α therapy (anti-TNF-α), one-third of them still require surgery. There is limited data as to whether anti-TNF-α influences postoperative complications. We evaluated postoperative complications in patients who were or were not exposed to anti-TNF-α therapy in our institutional cohort. MATERIALS AND METHODS: A retrospective review of CD patients who underwent abdominal surgery between September 2013 and September 2018 was performed. The patients were divided into two groups based on whether they were treated with anti-TNF-α within 90 days before surgery. Thirty-day postoperative complications were assessed using Clavien-Dindo classification (D-C); this examination included surgical site infections (SSIs), stoma complications, intra-abdominal septic complications, non-SSIs, bleeding, ileus, readmission rate, and return to the operating room. Mann-Whitney U-test, Fisher's exact test, and multivariate logistic regression analyses were used for statistical analysis. RESULTS: Sixty-five patients (41 males) with a median age of 16 years (range: 7-19) at the time of operation were identified. The most common surgery was ileocecal resection in 49 (75%) patients. Forty-three (66.2%) patients were treated with anti-TNF-α preoperatively. Seven patients (11%) experienced postoperative complications. There was no statistically significant difference in postoperative complication in patients who did or did not receive anti-TNF-α before surgery (D-C minor 2.3% vs. 4.6%, p = 1; D-C major 7% vs. 9.1%, p = 1). CONCLUSION: The use of anti-TNF-α in pediatric CD patients within the 90 days prior to their abdominal surgery was not associated with an increased risk of 30-day postoperative complications.

OBJECTIVES: Intestinal surgery is an important part of Crohn disease (CD) treatment in children. The aim of the present study was to compare the rate of endoscopic recurrence at the sixth month after ileocecal resection (ICR) in children with CD treated with azathioprine between patients who received prior antitumor necrosis factor alpha (anti-TNF-α) therapy and those who were not administered this therapy. Moreover, we tried to identify the potential risk factors for disease recurrence and describe the schedule of long-term follow-up after surgery. METHODS: We prospectively collected data from pediatric patients with CD, who underwent ICR between October 2011 and June 2015 at our hospital and were treated with azathioprine monotherapy after ICR. We evaluated the endoscopic recurrence (Rutgeerts score) at the sixth month after ICR in all included patients. RESULTS: Among 21 included patients, 13 achieved endoscopic remission (Rutgeerts score < i2) at the sixth month after ICR. No difference was found between patients who received prior anti-TNF-α therapy and those who did not. We did not find any clinically relevant factors associated with endoscopic recurrence rate at the sixth month. CONCLUSIONS: Prior anti-TNF-α therapy does not seem to be a strong risk factor for endoscopic recurrence within 6 months after ICR. Further studies on large sample of patients are needed to identify potential predictors of disease recurrence.

AIM: The aim of this study was to analyze complications and outcomes of end-to-end urethral anastomosis performed for posttraumatic bulbar strictures or posterior urethral injuries in pediatric patients. METHODS: The records of 15 boys, age 18 years and below, admitted to our tertiary trauma center with urethral injuries from 1989 to 2014 were reviewed retrospectively. Out of these 15 boys, 7 were excluded (2 for iatrogenic trauma, 2 for minor straddle injuries who were not operated on, 2 for incomplete records, and 1 lost to follow-up) and 8 analyzed patients were operated for bulbar or posterior urethral injury. The mean follow-up after the operation was 4.5 years (range 0.5-10). To obtain up-to-date follow-up information, all the analyzed patients were contacted by a letter and telephone in January 2015 and asked about lower urinary tract or erectile dysfunction (ED) using the International Index of Erectile Function-5 questionnaire. RESULTS: Mean age at the time of injury was 12.3 years (range 5-17). Four patients with pelvic fracture had complete posterior urethra disruption, three patients after straddle injury developed obliterating stricture of the bulbar urethra and one patient had torn his bulbar urethra apart by a sharp hook. Except for the immediate exploration of the open perineal wound, all patients were operated via perineal approach 1 to 6 months after initial suprapubic catheter insertion. Five patients needed a cystotomy to identify the proximal urethral stump by a probe, and two patients had partial pubectomy to gain urethral length. Postoperative complications included stricture in anastomosis in six patients (all reoperated, four more than once including attempts of endoscopic internal urethrotomy). Six days after surgery, one patient developed massive external bleeding around a permanent urinary catheter due to a posttraumatic ruptured arterial aneurysm that was later stopped by urgent angiography and coil insertion. After discharge, three patients had transient stress incontinence. All patients had uroflowmetry maximum flow above 20 mL/s on their last follow-up except for two (12 and 15 mL/s). None have any lower urinary tract dysfunction symptoms in adulthood; one suffers from mild ED and two report moderate ED due to penile shortening. CONCLUSION: Delayed end-to-end anastomosis for pediatric urethral injury is a safe operational option. However, high rate of short-term complications and reoperations should be expected. Penile shortening is one of the most severe long-term complications.
