A prospective randomized comparative study on the use of ventral subcutaneous flap to prevent fistulas in the Snodgrass repair for distal hypospadias.
No full textWe evaluated the importance of urethral coverage using vascularized subcutaneous ventral flaps for the prevention of fistulas in patients undergoing distal hypospadias repair. Our prospective study included 130 patients, aged 9 months to 12 years, who underwent distal hypospadias repair using tubularized incised plate urethroplasty (TIPU), from January 2001 through January 2006. Patients were assigned to one of two groups by a computer-generated random selection: 65 patients underwent non-covered urethroplasty (NCU group); another group of 65 patients underwent covered urethroplasty (CU group) with a vascularized subcutaneous ventral flap. The results were evaluated by two pediatric surgeons unaware of the type of treatment each patient had undergone. Successful results were achieved in 99/130 patients (76.2%). We recorded 31 (23.8%) post-operative complications: 20 patients presented with a urethrocutaneous fistula (15 patients in the NCU group and 5 in the CU group); five with urethral stenosis (3 in the NCU and 2 in the CU group); and six with skin dehiscence of the preputioplasty (3 patients in each group). We analyzed the results using the chi2 test and the only statistically significant difference between the two groups (p < 0.05) was in terms of incidence of fistulas. Urethrocutaneous fistulas seem to be the most frequent complication of distal hypospadias after TIPU repair. Urethral coverage should be part of the Snodgrass procedure because it significantly reduces the formation of fistulas. A well-vascularized subcutaneous ventral flap represents, in our experience, a simple and optimal choice for the prevention of fistulas
The efficacy of laparoscopy in detecting and treating associated congenital malformations in children
No full textOne of the main advantages of laparoscopy in children is the fact that it enables a magnified
view and the possibility to explore the whole abdominal cavity. This case report clearly
shows these advantages. We report the case of a 3-yr-old girl, suffering from severe GERD
and right inguinal inguinal hernia, who had already been operated at birth for esophageal
atresia. We performed a laparoscopic fundoplication according to Nissen and, at the end of
procedure, we decided to turn the optic down to control the right inguinal region to confirm
the presence of an inguinal hernia. To our great surprise we found a right oblique external
hernia as well as a direct inguinal hernia on the same side. Both hernias was treated
successfully in laparoscopy. At a 1-year follow-up, the patient presented no reflux and no
recurrence of the inguinal hernias. The laparoscopy in this case permitted operation on two
different pathologies involving the upper and lower parts of the abdominal cavity using the
same ports and without enlarging the incision, as would happen in laparotomy. The main
relevance of this case is that laparoscopy allowed the detection of an associated pathology
like a direct inguinal hernia that would have been certainly overlooked in open surgery and
could have caused a recurrent hernia if operated via open surgery
