- Single-stage Abdominoplasty Using Groin Flaps Without Osteotomies: Management of Exstrophy-epispadias Complex(2018) GIRON, Amilcar Martins; MELLO, Marcos Figueiredo; BERJEAUT, Ricardo Haidar; MACHADO, Marcos Giannetti; SILVA, Gabriel Carvalho dos Anjos; CEZARINO, Bruno Nicolino; OLIVEIRA, Lorena Marcalo; LOPES, Roberto Iglesias; DENES, Francisco TiborBACKGROUND The optimal treatment for children born with exstrophy-epispadia complex is still a matter of AND OBJECTIVE debate.(1,2,3) We demonstrate the Single-Stage Abdominoplasty using Groin Flap technique to close the abdominal wall of children with classic bladder exstrophy (CBE) without osteotomy neither radical soft tissue mobilization. Advantages over current techniques are less risk of penile tissue loss and avoidance of osteotomies. MATERIAL AND METHODS Abdominal wall repair consists in using the hypogastric skin, rectus, and obliquus externus abdom inalis muscle fascial flaps. These groin flaps are rotated medially resulting in a very strong abdominal wall support. Groin flaps are made of rectus anterior fascia rotated medially, flipped over, and sutured with Prolene sutures to close the defect. By rotating the fascial flaps medially, complete reinforcement of the abdominal wall to the level of the pubic bone is achieved. This permits abdominal closure maintenance without tension. RESULTS Groin flap was applied to 128 patients with CBE referenced from all over the country. Most of these patients returned to their home areas making difficult their follow up. However, we have 44 cases that have regular clinical visits. Mean follow-up was 10.3 4.5 years (2 years 8 months-16 years). Successful closure was achieved in 43 patients (97.7%) as a single procedure; one patient had a complete wound dehiscence and needed another reconstruction (2.2%). Four patients (9.1%) presented abdominal hernias that needed surgical management. When continence is evaluated, we present similar literature rates (60%).(4) CONCLUSION Abdominal reconstruction using Groin flaps has advantages over the traditional approaches to CBE. It reduces the surgical steps and facilitates the closure of the abdominal wall without the need of osteotomies and consequent immobilization during the postoperative period. It is feasible at any age and can be also very useful as a salvage technique even after previous failed procedures. Finally, it minimizes the number of surgeries. (C) 2018 Elsevier Inc.
bookPart Escroto agudo(2019) CEZARINO, Bruno Nicolino; OLIVEIRA, Lorena Marçalo; MESQUITA, José Luis Borges- Diagnostic work-up and laparoscopic correction of an ectopic ureter(2015) CEZARINO, B. N.; LOPES, R. I.; OLIVEIRA, L. M.; DENES, F. T.; SROUGI, M.Introduction A duplex renal collecting system is a common congenital anomaly in children. Continuous dribbling (especially if after the toilet-training period) should raise suspicion of the presence of an ectopic ureter, which is most often associated with ureteral duplication. This video will demonstrate the complete diagnostic work-up necessary in these cases. Case report A 10-year-old girl presented with continuous dribbling. Ultrasonography and computerized tomography depicted a duplex system on the left side, with the upper pole ureter ectopically inserting into the vaginal cavity and good upper pole renal parenchyma. A careful urethrocystoscopy showed a topic right ureteral orifice and a topic lower pole left ureteral orifice. Retrograde pyelography was performed and displayed normal left lower pole anatomy. A vaginography was performed, which showed reflux to the ectopic ureter. Vaginoscopy clearly identified the ectopic ureteral orifice. A guide wire was introduced through this meatus and retrograde contrast injection confirmed the diagnosis of an ectopic ureter. Results At laparoscopy, a larger upper pole ureter and a normal lower pole ureter on the left side were identified. A termino-lateral ureteroureteral anastomosis was performed. After the procedure, the child reported immediate resolution of urinary dribbling. Conclusion In order to optimize its surgical correction, efforts should be made to appropriate localization of the ectopic ureter.
- Reoperative Laparoscopic Ureteropelvic Junction Obstruction Repair in Children: Safety and Efficacy of the Technique(2017) MOSCARDI, Paulo Renato Marcelo; BARBOSA, Joao Arthur Brunhara Alves; ANDRADE, Hiury Silva; MELLO, Marcos Figueiredo; CEZARINO, Bruno Nicolino; OLIVEIRA, Lorena Marcalo; SROUGI, Miguel; DENES, Francisco Tibor; LOPES, Roberto IglesiasPurpose: Failure after pyeloplasty for ureteropelvic junction obstruction in children may occur in up to 10% of cases. Therapeutic options include Double-J (R) stent placement, endoscopic treatment and reoperation. Laparoscopic and robotic reoperative modalities seem safe and efficacious, although pediatric series are limited in the literature. We report the largest known series of reoperative laparoscopic ureteropelvic junction obstruction repair in children and compare this approach to primary laparoscopic pyeloplasty. Materials and Methods: We reviewed all children undergoing laparoscopic pyeloplasty at a single institution from 2004 to 2015. Reoperative laparoscopic ureteropelvic junction obstruction repair was compared to primary pyeloplasty. Groups were analyzed regarding demographics, operative time, complications, length of hospital stay and success, defined by improvement of symptoms, ultrasound and renogram. Results: We identified 11 cases of reoperation (8 redo pyeloplasties and 3 ureterocalycostomies) and 71 primary pyeloplasties. Groups were not different in age, gender or weight. Median followup was 37 months. Median time between primary pyeloplasty and reoperation was 34 months. Median operative time was 205 minutes for the reoperative group and 200 for primary pyeloplasty (p = 0.98). Length of stay was longer in the reoperative group (p = 0.049), although no major complications were recorded in this group. All reoperative cases and 96% of primary pyeloplasty cases remained asymptomatic following surgery (p = 0.99). Postoperative improvement was similar for both groups on ultrasound (90% for reoperation vs 92% for primary pyeloplasty, p = 0.99) and renogram (80% vs 88%, p = 0.6). Conclusions: Laparoscopy seems to be safe and effective for management of failed pyeloplasty in children. Based on our data, reoperation is as safe and effective as primary pyeloplasty.
