The effectiveness of double dorsal dartos flap for urethroplasty coverage in distal hypospadias repair: A single surgeon approach to preventing urethrocutaneous fistula.

PURPOSE: The concept of interposing double dorsal preputial flaps to cover the urethroplasty was introduced in 2005 to reduce the risk of urethrocutaneous fistula (UCF). Our study aims to compare the postoperative outcomes of urethroplasty for distal hypospadias between two groups: one receiving single preputial flap coverage and another receiving double flap coverage. MATERIALS AND METHODS: We conducted a retrospective analysis study of boys with primary distal hypospadias who underwent surgery by the same experienced surgeon, at our department between 2010 and 2021. The study population was divided into two groups: Group A, which underwent urethroplasty coverage with single dorsal preputial flap, and Group B, which underwent coverage with double flap. Postoperative complications were compared between the two groups. RESULTS: We collected 105 cases, comprising 51 in Group A and 54 cases in Group B. The mean age at surgery was 29 months in Group A and 24 months in Group B. Post-operative follow-up period ranged from 6 months to 8 years. Functional and cosmetic outcomes were judged excellent in 88.7%. Only 10 boys experienced complications requiring reoperation. UCF occurred in 5 patients from Group A, while no cases were reported in Group B (p = 0.024). Meatal stenosis was identified in three patients in Group A and in two patients in Group B (p = 1). No other complications, such as glans dehiscence or penile torsion, were noted. CONCLUSION: Double dorsal dartos flap is an effective method for covering the new urethra and can be recommended in the treatment of patients with virgin distal hypospadias.

Phenotypic variability and management of patients with mosaic monosomy X and Y chromosome material: a case series.

BACKGROUND: we aim to discuss the origin and the differences of the phenotypic features and the management care of rare form of disorder of sex development due to Mosaic monosomy X and Y chromosome materiel. METHODS: We report our experience with patients harboring mosaic monosomy X and Y chromosome material diagnosed by blood cells karyotypes and cared for in our department from 2005 to 2022. RESULTS: We have included five infants in our study. The current average age was 8 years. In four cases, the diagnosis was still after born and it was at the age of 15 years in one case. Physical examination revealed a variable degree of virilization, ranging from a normal male phallus with unilateral ectopic gonad to ambiguous with a genital tubercle and bilateral not palpable gonads in four cases and normal female external genitalia in patient 5. Karyotype found 45, X/46, XY mosaicism in patient 1 and 2 and 45, X/46, X, der (Y) mosaicism in patient 3, 4 and 5. Three cases were assigned to male gender and two cases were assigned to female. After radiologic and histologic exploration, four patients had been explored by laparoscopy to perform gonadectomy in two cases and Mullerian derivative resection in the other. Urethroplasty was done in two cases of posterior hypospadias. Gender identity was concordant with the sex of assignment at birth in only 3 cases. CONCLUSION: Because of the phenotypic heterogeneity of this sexual disorders and the variability of its management care, then the decision should rely on a multidisciplinary team approach.

Outcomes of pneumatic dilation in pediatric caustic esophageal strictures: a descriptive and analytic study from a developing country.

OBJECTIVES: Corrosive substance ingestion in children represents a significant public health issue due to its long-term health sequelae. Esophageal stricture, main complication of this dangerous condition, is treated by pneumatic dilation and eventually by esophageal replacement. We aimed, through this study, to report the outcomes of esophageal pneumatic dilation complicating corrosive substance ingestion in children in a developing country. METHODS: This cross-sectional study was performed on the population of pediatric patients with caustic esophageal stenosis between January 2005 and December 2020. All patients underwent pneumatic balloon dilation. A logistic regression model was built to predict the probability of the occurrence of the event (success/failure) of the dilation. The ROC curve is used to evaluate the performance of the logistic regression model to discriminate between positive and negative values of the dependent variable. RESULTS: The success rate of pneumatic balloon dilation was 80.4%. The median duration of overall management was 11 months. The severity of caustic stricture observed during endoscopy was significantly linked to worse outcomes (p = 0.001). Multivariate analysis indicated that the severity of stenosis and the number of dilation sessions were independent risk factors for failure of dilation. ROC curve analysis showed that the area under the curve was 71.7%. A Cut-Off point value of 7 provided the best sensitivity and specificity. CONCLUSION: Pneumatic balloon dilation has been proven to be efficacious in infants with caustic esophageal stricture. Pediatric surgeons should take into account factors to promptly switch to replacement surgery and avoid unnecessary and time-consuming serial dilations.

Management of trichobezoar: About 6 cases.

BACKGROUND: Trichobezoar is an uncommon clinical entity in which ingested hair mass accumulates within the digestive tract. It is generally observed in children and young females with psychological disorders. It can either be found as an isolated mass in the stomach or may extend into the intestine. Untreated cases may lead to grave complications. MATERIAL AND METHODS: We retrospectively analyzed the clinical data of six patients treated for trichobezoar in Monastir pediatric surgery department during 16-year-period between 2004 and 2019. Imaging (abdominal computed tomography and upper gastroduodenal opacification) and gastroduodenal endoscopy were tools of diagnosis. RESULTS: Our study involved 6 girls aged 4 to 12. Symptoms were epigastric pain associated with vomiting of recently ingested food in 3 cases and weight loss in one case. Physical examination found a hard epigastric mass in all cases. The trichobezoar was confined to the stomach in 4 cases. An extension into the jejunum was observed in 2 cases. Surgery was indicated in all patients. In two cases, the attempt of endoscopic extraction failed and patients were then operated on. All patients had gastrotomy to extract the whole bezoar even those with jejunal extension. Psychiatric follow-up was indicated in all cases. The six girls have evolved well and did not present any recurrence. CONCLUSION: open surgery still plays a crucial role in Trichobezoard management . After successful treatment, psychiatric consultation is imperative to prevent reccurrence and improve long term prognosis.

Femoral hernia in children: How to avoid misdiagnosis?

BACKGROUND: Femoral hernias are an uncommon groin pathology among pediatric patients. Therefore, they are frequently misdiagnosed. In the present study, we review our experience with this rare surgical entity during the past 25 years. METHODS: The medical records of 19 patients who underwent 22 femoral hernia repairs between January 1994 and December 2019 were retrospectively analysed. RESULTS: Patients' age ranged from 2 to 12 years (mean age was 5. 5 years) with an approximately equal sex ratio (10 girls/9 boys). There were three bilateral cases identified separately. They were discovered and managed at different times. All the children were referred with a groin lump, but the correct pre-operative diagnosis was made in only 13 cases (59%). In the remaining cases, four were identified intraoperatively following negative exploration for a supposed inguinal hernia. The other five were found to have a femoral hernia 1 month to 12 months after ipsilateral inguinal hernia repair. All patients underwent elective surgery. The femoral canal was closed using either Lytle or McVay procedure. Recurrence occurred in only one patient 2 months after initial repair. CONCLUSION: Femoral hernias are often misdiagnosed. Pre-operative diagnosis can be obtained through careful clinical assessment. In equivocal cases, ultrasonography and laparoscopy could be useful. A correct pre-operative diagnosis will lead to suitable treatment, thus avoiding unnecessary reoperations and their related complications.
