Malrotation volvulus in a neonate: a novel surgical approach.

A newborn presented with bilious vomiting secondary to a malrotation and presumed perinatal-onset volvulus. Laparotomy was performed at 20 h of age at which the volvulus was derotated. Nevertheless the small but not the large bowel appeared to be completely ischaemic and non-viable. A second-look laparotomy was performed 24 h later with no significant improvement. In a new approach to the problem, nothing further was done and the child was left alone on parenteral nutrition and naso-gastric aspiration for 11 weeks. Further exploration showed that 40 cm of small bowel had survived intact and restorative surgery was carried out. Parenteral nutrition was discontinued after 9 months and the child, now aged 3.5 years, is thriving.

Distal hypospadias: which repair?

OBJECTIVE: To compare the function, complications and cosmesis after a modified Thiersch-Duplay and Mathieu unstented urethroplasty. PATIENTS AND METHODS: Over a 5-year period 381 consecutive patients (not randomized) with distal hypospadias were evaluated. A modified Thiersch-Duplay with dorsal incised urethral plate tubularization (group A) was undertaken in 170 (45%) and a parameatal based flip-flap Mathieu hypospadias repair (group B) in 211 (55%). No urinary diversion or stent was used in any of the 381 patients. RESULTS: In both groups the mean (sd) follow-up was 3.1 (1.4) years. All 381 patients voided spontaneously after surgery and none developed urinary retention needing catheterization. In groups A and B, respectively, the overall late complications were 12 (7.1%) and 32 (15.2%) (P=0.001), with urethrocutaneous fistula in six (3.5%) and 26 (12.3%; P=0.001); secondary surgery for fistula repair was successful in all boys in A and 89% in B. The glanular meatus was a vertical slit in all in group A and 86% in B (P=0.02). In both groups, 71% of the children who are now toilet-trained and standing to void have a good calibre, single and straight urinary stream in a forward direction. CONCLUSIONS: Stenting or urinary diversion is unnecessary after distal hypospadias surgery. The functional results were good in those standing to void. A more natural vertical slit-like glanular meatus was easily created using the modified Thiersch-Duplay urethroplasty, with a lower fistula rate.

Staged proximal hypospadias repair: Modified thiersch duplay with midline incision in urethral plate followed by Mathieu urethroplasty.

PURPOSE: Functional results, complications, cosmesis, operating time, and hospital stay were analyzed after staged urethroplasty for proximal hypospadias. METHODS: Seventeen consecutive boys, mean age 17.7 +/- 1.6 months underwent a staged urethroplasty in the past 5 years. Urethral plate was tubularized and proximal hypospadias converted to distal. Hooded dorsal prepuce was buttonholed and transposed ventrally to cover the neo-urethra. Subsequently, a parameatal based flip flap urethroplasty completed the urethral reconstruction at mean age of 26.7 +/- 4.1 months. RESULTS: Mean follow-up time was 2.8 +/- 1.7 years. Eighty-eight percent of boys who are now toilet trained and standing to void have a good caliber straight single stream of urine in a forward direction. Urethrocutaneous fistula was seen in 1 child (6%), and a simple fistulectomy with double layered closure was successful at first attempt of fistula closure. Cosmetic appearance of a natural vertical slit glanular meatus situated at normal position on the glans was achieved in all patients. Total mean operating time was 193.5 +/- 42.9 minutes and total mean duration of hospital stay was 3.4 +/- 0.6 days. CONCLUSION: Staged urethroplasty for proximal hypospadias results in a normal penis with good function, minimal complications, and excellent cosmesis.

Xanthogranulomatous pyelonephritis in childhood.

PURPOSE: Demographic data, clinical presentation, associated abnormalities, and radiologic findings were evaluated to outline diagnostic criteria that may lead to the diagnosis of xanthogranulomatous pyelonephritis in children. METHODS: Eleven boys and 8 girls with a mean age of 3.4 +/- 1.7 years were classified into obstructive xanthogranulomatous pyelonephritis (n = 13), which was associated with nephrolithiasis and nonobstructive (n = 6), which mimicked Wilms' tumor. RESULTS: Twelve children with obstructive diffuse involvement of the renal parenchyma, 1 with left-sided obstructive focal involvement in a horseshoe kidney (group 1), and 6 with nonobstructive diffuse xanthogranulomatous pyelonephritis (group 2) showed a male to female ratio of 1.2:1 and 2:1, respectively. Mean age was 4.1 +/- 1.2 years in group 1 versus 1.8 +/- 1.5 years in group 2; P =.001. The common features were renal mass, hematuria, and anemia (100%; P =.07) and leucocytosis (77% v 83%; P =.097). Main differences between the 2 groups were acute inflammatory syndrome (0 v 33%; P =.01), recurrent urinary infection (54% v 17%; P =.05), isolation of Proteus mirabilis as a pathogen (69% v 0; P =.001), and renal stones (100% v 0; P =.001). Preoperative diagnosis was accurate in all 13 (100%) children with obstructive xanthogranulomatous pyelonephritis. Radiologic features that were not consistent with Wilms' tumor in group 2 were absence of sharp definition and encapsulation of the mass, ill-defined margins with inflammatory infiltration of the perinephric fat and focal inflammatory tissue destruction. Nephrectomy was technically difficult because of extensive adhesions to the retroperitoneum, psoas muscle, and surrounding structures in both groups. CONCLUSIONS: Xanthogranulomatous pyelonephritis must be considered in the differential diagnosis of a child presenting with a renal mass, anemia, and elevated inflammatory markers. Treatment by nephrectomy is curative. J Pediatr Surg 36:598-601.

Proximal hypospadias. Comparative evaluation of staged urethroplasty (modified Thiersch Duplay followed by Mathieu) and single stage on-lay island flap repair.

OBJECTIVES: Comparative analysis of functional results, complications, cosmesis, operative time and hospital stay between staged urethroplasty and single-stage on-lay island flap for proximal hypospadias. MATERIALS AND METHODS: Non-randomised single observer study of two groups of patients over a 5-year period with proximal hypospadias. Group 1 had 17 patients (mean age 17.7+/-1.6 months) who underwent a staged urethroplasty. Urethral plate was tubularised and proximal hypospadias converted to a distal hypospadias. Hooded dorsal prepuce was buttonholed and transposed ventrally to cover the neo-urethra. Subsequently a parameatal based flip flap urethroplasty completed urethral reconstruction. Group 2 had 17 patients (mean age 18.2+/-2.2 months) with a single stage inner preputial on-lay island flap based on superficial dorsal vessels. RESULTS: Mean period of follow-up has been 2.8+/-1.7 years in group 1 vs. 3.2+/-1.6 years in group 2 (p = 0.2). In both groups (34), 79% of the children who are now toilet trained and standing to void have a good calibre straight single stream of urine in a forward direction (p = 1.00). Main complication seen in both groups was urethrocutaneous fistulae: 6% (1/17) in group 1 vs. 59% (10/17) in group 2 (p = 0.0002). In both groups (34) cosmetic appearance of a natural vertical slit glanular meatus situated at the normal position on the glans was achieved (p = 1.00). Total mean duration of operative time in group 1 was 193.5+/-42.9 vs. 203+/-27.6 min in group 2 (p = 0.24). Total mean duration of hospital stay in group 1 was 3.4+/-0.6 vs. 9.2+/-2.9 days in group 2 (p = 0.0001). Total mean cost of the procedure in group 1 was 2,347.3 pounds +/- 220 vs. 3,753.5 pounds +/- 75 in group 2 (p = 0.002). CONCLUSION: Staged urethroplasty for proximal hypospadias results in a normal penis with good function, minimal complications and excellent cosmesis. Hospital stay was shorter and overall cost lower than a single stage on-lay island flap urethroplasty.

Volvulus of the transverse and sigmoid colon.

A case of transverse and sigmoid-colon volvulus and a discussion of the probable mechanism of large-bowel volvulus (LBV) in children and its management is presented. A 5-year-old male with cerebral palsy presented with transverse-colon and subsequently sigmoid volvulus. The child underwent resection of the involved segments with primary colocolic and colorectal anastomosis, respectively. The recovery was uneventful. LBV in children is due to congenital anomalous or absent ligamentous fixation of the colon. Constipation is probably the result of the volvulus. Resection of the involved segment and primary anastomosis is the definitive treatment.

Large bowel volvulus in childhood.

BACKGROUND: Large bowel volvulus is extremely uncommon in children. The probable pathogenesis, predisposing factors and management of large bowel volvulus in children are debatable. METHODS: Seven consecutive cases of large bowel volvulus occurring over a 6-year period are reported. RESULTS: Two patients with caecal volvulus, one with transverse and subsequent sigmoid volvulus, one with transverse colon volvulus and three children with sigmoid volvulus are reported. Four girls and one boy with cerebral palsy, one female with Moya Moya disease and spastic paraplegia and an otherwise healthy boy presented at a mean age of 8.3 years (range: 3-15 years). The common presentation was abdominal distension (n = 6), tenderness (n = 6), constipation (n = 7) and bloody mucoid discharge per rectum (n = 6). Plain abdominal X-ray and barium enema were diagnostic. Resection with primary ileocolic, colocolic or colorectal anastomosis was performed in all cases. The mean follow-up was 3.4 years (range: 1-6 years) and there was no mortality. CONCLUSIONS: Large bowel volvulus in children may be due to congenital anomalous or absent ligamentous fixation of the large bowel, and abnormal mesocolon or a common ileocolo-mesentery. Large bowel obstruction due to volvulus must be considered in the differential diagnosis in a child presenting with constipation associated with bloody mucoid discharge per rectum. Resection of the involved segment and primary anastomosis is the definitive treatment for large bowel volvulus in children.

Preputial intussusception or acquired megaprepuce.

Preputial intussusception, or acquired megaprepuce, is a clinical condition whose incidence is increasing. It results from infolding of the outer preputial skin, obstruction of urinary flow, and the development of a phimosis. With time the process continues, resulting in a distinctive clinical picture. Treatment by early circumcision cures the problem and allows resolution of the sequelae.
