Do patch procedures prevent complications of the Mathieu technique?

PURPOSE: The effects of V-incision sutured (MAVIS) and dartos patch reinforcement techniques in reducing side effects and complications of the Mathieu procedure and improving the appearance of the meatus are evaluated. MATERIALS AND METHODS: A total of 74 patients with distal shaft hypospadias without chordee or with minimal chordee were operated on by a single surgeon using Mathieu's technique. While only the classic Mathieu repair was performed in group 1, MAVIS and dorsal dartos patch reinforcement was included with the procedure in group 2. A silicone urethral catheter and foam silicone dressing were used in both patient groups. RESULTS: There were 32 cases in group 1 and 42 in group 2. Median patient age at operation was 3.2 and 3.4 years in groups 1 and 2, respectively. Mean postoperative period for the silicone catheter was 4.9 days in both groups. Followup ranged from 52 to 128 months (mean 76) for group 1 and 13 to 43 months (25.4) for group 2. Five fistulas and 1 meatal stricture developed in group 1 and all the children in this group required meatal calibration with dilatation in some. Neither fistula nor stricture occurred in group 2 and there was no need for calibration. A slit-like meatus was achieved in all children in group 2 but in only 12 in group 1. CONCLUSIONS: The MAVIS technique and dorsal dartos patch reinforcement may prevent complications of the classic Mathieu procedure. A slit-like meatus was obtained in all cases with this approach.

Pyloric atresia: 15-year review from a single institution.

BACKGROUND: Pyloric atresia (PA) is a rare pathology. Calder presented the first pyloric atresia case in 1749 and Touroff, Sussman, Meltz, and their colleagues presented the first successful operation in 1940. PA has 3 types of anatomic variations: (1) type A, pyloric membrane or web; (2) type B, the pyloric channel is a solid cord; and (3) type C, in which there is a gap between the stomach and duodenum. Associated anomalies also have been described. Epidermolysis bullosa (EB) and intestinal anomalies occur most often with this condition. METHODS: Charts of 16 cases of congenital PA, aged 1 to 30 days and admitted to our department between 1986 and 2001, were studied retrospectively in regard to sex, prenatal diagnosis, presence of polyhydramnios, time of admission, pathology, type of operation, associated anomalies, and mortality rate. RESULTS: In the study group, the male to female ratio was 5:3, the mean birth weight was 2,312 g and the mean age of admission was 6.5 days. The distribution of the anatomic variations was type A in 9 (56.3%) and type B in 7 (43.7%) of cases. Associated anomalies were present in 7 cases (43.8%). Familial occurrence was a prominent feature of our series. Seven of 16 cases occurred in 3 families. We performed 9 web excisions together with Heineke Mikulicz (H-M) pyloroplasty, 5 atresia excisions and gastro-duodenostomy, and 2 H-M pyloroplasties alone. Stamm gastrostomy was supplemented in 3 cases. The overall mortality rate (n = 9) was 56.3%. CONCLUSIONS: Pyloric atresia can be managed successfully if it is diagnosed early. In this group of patients, congenital anomalies or septicemia are the main causes of mortality.

Esophageal variceal bleeding secondary to portal hypertension: endoscopic sclerotherapy as the first-step treatment.

BACKGROUND: Variceal bleeding from the esophagus is an important cause of mortality and morbidity in children with portal hypertension (PHT). PATIENTS AND METHODS: A series of 69 PHT cases (41 intrahepatic, 28 extrahepatic) have been evaluated in our department since 1990. According to the Child-Pugh classification, 49 cases were in class A, 16 cases were in class B, and 4 cases were in class C at admission. In our protocol, endoscopic sclerotherapy is performed in all patients, and the diagnosis is achieved directly by diagnostic laparoscopy and fine-needle liver biopsy. The procedure is applied under general anesthesia, and 1% aethoxysclerol (polidocanol) is injected paravariceally and intravariceally with the use of a flexible endoscope. RESULTS: The Sugiura procedure was performed in nine patients who presented with recurrent bleeding episodes despite the strict sclerotherapy protocol. Liver transplantation was performed in two patients who were in Child class C. The total mortality rate in this series was 7% (5/69). CONCLUSION: Endoscopic sclerotherapy, as presented herein, decreases the need for additional surgical interventions in children with PHT.

Arterial carbon dioxide markedly increases during diagnostic laparoscopy in portal hypertensive children.

UNLABELLED: Several factors are responsible for hypercarbia during laparoscopic procedures. This study was undertaken because we observed a sudden increase in PaCO(2) in children with portal hypertension (PHT), which was unusual in healthy children undergoing laparoscopic procedures. Fifty-seven children underwent laparoscopic procedures under general anesthesia and were mechanically ventilated. Arterial blood samples were obtained 5 min after intubation (T(0)), 15 min and 30 min after CO(2) pneumoperitoneum (T(15) and T(30)), 5 min after desufflation (T(end)), and 10 min after extubation (T(ext)) for blood gas analysis. The changes in PaCO(2), pH, and ETCO(2) were statistically significant during the study periods in both groups (P < 0.05). The percentage of PaCO(2) increase between T(0) and T(15) was 11.5% and 20.1%, respectively, in the control group and the PHT group (P < 0.05). This increase reached 36.8% at T(30) in the PHT group, whereas the control group had a 17.2% increase (P < 0.05). ETCO(2) presented similar changes. The variability in base excess, bicarbonate, PaO(2), arterial oxygen saturation, and SpO(2) was not significant in either group (P > 0.05). The PaCO(2) increased remarkably in children with PHT undergoing laparoscopy, with no difference in intrahepatic or extrahepatic origin. Limiting the duration of CO(2) pneumoperitoneum and intraabdominal pressure and adjusting ventilatory variables to accommodate hypercarbia are of the utmost importance for such cases. IMPLICATIONS: We compared children with portal hypertension with systemically healthy children during laparoscopy. The increase in arterial and end-tidal CO(2) was remarkable in children with portal hypertension, regardless of bicarbonate changes. Managing ventilation to accommodate hypercarbia is of the utmost importance for such cases.

Nonsurgical diagnosis and management of an inflammatory pseudotumor of the spleen in a child.

Primary splenic tumors in children are rare and usually benign. We report the case of a 7-year-old boy with a splenic mass that initially resembled an infectious process. Histopathologic examination of a specimen obtained using sonographically guided Tru-cut needle biopsy, performed after angiography, revealed an inflammatory pseudotumor of the spleen, an extremely rare benign lesion. The lesion has been managed conservatively with clinical and sonographic follow-up. This case shows that benign lesions of the spleen can easily be diagnosed using current radiologic and histopathologic techniques without the need for surgery, thus allowing total or even partial splenectomy to be reserved for patients in whom a mass cannot be diagnosed or in whom clinical progression is evident.
