[The split notochord syndrome. A report of 2 cases].

Split notochord syndrome has been described in several previous case reports; however, we recently treated two patients with a previous undescribed variant of this syndrome. A 2,800 g male baby was admitted to the neonatal patients room with a non covered mass on the lumbo-sacral region, and a portion of intestine, with meconium being passed attached to it the legs were equine-varus and the anus was absent. Radiographs were consistent with a double spine defect (lumbar and sacral split notochord), and the patient was taken to the operating room for closure. A 2,600 g male baby was first seen in other hospital, and was admitted with a circular defect in the mid-line of the lumbosacral region. This defect was conformed by knee, leg, ankle and fingers. Radiographs showed bony structures consistent with incomplete lower extremity. During surgery, the skin overlying the mass was excised, showing a wide spine defect including stomach, duodenum, jejunum, ileum and colon, covered by a peritoneal membrane; there was not communication between this structure and the normal digestive tract.

[Bochdalek hernia with late manifestation. Relevant clinico-surgical features].

INTRODUCTION: Congenital diaphragmatic hernia presents after the first hours of life in 5 to 25% of cases. Presenting symptoms may be quite non-specific, and gastrointestinal rather than respiratory in origin. Bochdalek hernia should be considered when an infant has respiratory distress, vomiting and abdominal pain. MATERIAL AND METHOD: Five-year retrospective study was made of children with congenital posterolateral (Bochdalek) hernia presenting more than 10 days after birth. The records are of 17 patients. The group was divided in two subgroups. The first, was made up of four patients who had digestive emergencies and complications such as colon and gastric perforation. One infant of this group had a left sided defect and inflammatory hepatic-pulmonary fusion. The second group was made up of 13 patients between 2 weeks and four years og age. Main complaints were vomiting, abdominal pain, and respiratory distress. Ten patients were female and 10 had a left-side defect. Herniated viscerae were small bowel, stomach, spleen, and colon. There were six deaths. CONCLUSIONS: Bochdalek hernia in children after the newborn period is a common entity. Frequent digestive and respiratory signs are present. Complications such as colon and gastric perforation are common.

[Traumatic perforation of the small intestine in childhood].

INTRODUCTION: Traumatic perforation of the small bowel occurs in approximately 1 percent of children with either blunt or penetrating trauma to the abdomen. Difficulty in recognition of initial subtle signs of hollow viscus injury can lead to delay in both diagnosis and operative intervention. MATERIAL AND METHOD: Medical records for patients discharged with traumatic small bowel perforation from the General Surgery Department between 1991 and 1999 were reviewed. RESULTS: Bowel injuries were noted in 41 children. Blunt trauma (battered child syndrome, bike injuries, etc.), was responsible for 37 cases and penetrating wounds in three (firearm wounds and bike pedal accidents). There were 32 boys and a mean age of 6.8 years. The site of perforation was duodenal in four cases, jejunum in 21, and ileum in sixteen. Associated injuries occurred in 11 patients, including stomach, pancreas, liver, spleen, bladder, and ureter. Twenty-nine had simple closure, while seven were resected. Four children died. CONCLUSIONS: These injuries require prompt surgical intervention and are in general curable with excellent prognosis if one is alert to the possibility of their occurrence, if one is familiar with the approaches to prompt and accurate diagnosis, and if associated injuries are not serious.

[Interstitial gastric emphysema in children].

UNLABELLED: Gastric pneumatosis is an unusual clinical finding in infants and children and it appears in the three following similar conditions: pneumatosis cystoides; emphysematous gastritis, and gastric emphysema. MATERIALS METHODS AND RESULTS: The clinical pictures and radiographic appearance of this association are described in four patients in whom the clinical course made suspect interstitial gastric emphysema. Two patients had hypertrophic pyloric stenosis and two, unspecific erosive gastritis. In the first two patients, a Fredet-Ramstedt procedure was performed. All patients survived. Differential diagnostic considerations, the importance of correct radiological diagnosis, and the results of proper therapy are discussed. CONCLUSIONS: Pyloric and duodenal obstruction in infants is the main etiologic factor in gastric emphysema.

[Gunshot injuries in the pediatric area].

Gunshot and air weapon wounds in children have become a significant source of morbidity and mortality in our community in the last four years. Ninety five children, 15 years of age and younger, were admitted to the Pediatric Surgical Service for gunshot and air mechanism wounds during this period. Review of the circumstances of injury revealed that more than 50% were accidental 71% were male patients, and 65% were caused by gunshots and outside of the home. Thoracic region was affected in 42%; abdomen, 20%; skull, face and neck, 13.4%; lower extremities, 13.4%; upper extremities 9%; genitalia, 2.0%; and perineal region, 0.8%. Rapid resuscitation and triage of major injury allowed us a survival of 97%. Social service intervention and educational task can offer significant benefit to these children but, ultimately gun control laws with strict enforcement are needed to stop this type of violence toward children.
