Failure of the Nissen fundoplication can be secondary to disruption of the wrap or slippage of the stomach upward within the wrap. A modification of the Nissen fundoplication was devised and implemented between 1982 and 1995 to eliminate these complications. This report describes the modification and the results. Commonly, the Nissen fundoplication uses a single anterior row of sutures securing the wrapped stomach to the esophagus. This modification reinforces the wrap with two additional rows of suture, one right lateral and one left lateral, each further anchoring the wrapped stomach to the esophagus. This retrospective analysis compares the Nissen and modified Nissen fundoplications performed at our institution. Fundoplication operations were considered a failure if they required a reoperation secondary to wrap disruption or stomach slippage. Data were analyzed using the χ2 method. A total of 948 fundoplication procedures were performed; 326 Nissen and 622 modified Nissen. Follow-up ranged from 0.5 to 13 years (mean, 6 years). Thirteen wrap disruptions and six stomach slippages occurred in the Nissen group (5.8%); 10 wrap failures and no stomach slippages occurred in the modified Nissen group (1.6%), P < .05. The authors conclude that this modification of the Nissen fundoplication significantly reduces wrap disruptions and stomach slippages.

Data from 505 patients (1976 through 1995) who underwent anterior spinal exposure were retrospectively analyzed. There were 222 boys and 283 girls with a mean age of 14.5 years; 166 had thoracic exposure (T), 300 thoracoabdominal (TA), 44 retroperitoneal (R), and 7 transperitoneal (TP); 17 had repeat exposure (5 had initial exposure elsewhere); 70% had scoliosis, 25% kyphosis, 27% a neuromuscular disorder (NMD) and 6.7% a tumor. Average intensive-care-unit stay was 2.5 days, 6.2 days for NMD (P < .05); average ileus was 3.4 days, 4.1 days for NMD (P < .05); and average length of stay was 15.4 days for all patients, 19.3 days for NMD (P < .05). Mechanical ventilation over 96 hours was required in 31 patients, 66% had an NMD (P < .05). The morbidity rate was 9.8%, 10.1% for NMD; the morbidity rate was zero for tumor and repeat exposures. Mortality was zero. Over half of the vessel injuries (57%) and the urinary tract infections (60%) occurred in NMD patients. Differences between the 1976 through 1985 period and the 1986 through 1995 period were a shorter length of stay and a majority of one-stage combined exposures in the latter period. The authors conclude that anterior exposure of spinal deformities is well tolerated by most pediatric patients, and that this technique is easily adaptable to the resection of retroperitoneal and thoracolumbar tumors.

The risk of fatal hemorrhage may limit the completeness of resection in hepatic malignancies and in vascular extensions of Wilms' tumors. We have used Ein's technique of deep hypothermia (average 17 degrees C) with cardiac arrest (average 39 minutes) and exsanguination in performing five hepatic and two intravenous Wilms' tumor resections. The initial hepatic resection takes less than 15 minutes to perform in a bloodless field and the specimen is immediately examined by frozen section for determination of adequacy of margin. Additional resection is easily performed. Of four trisegmentectomies and one left lobectomy, two required additional resections. Mattress sutures were used to control hemorrhage during recirculation. One patient died from bleeding and cardiac decompensation and another from recurrence of tumor. The Wilms' tumors extended from the iliac vein into the right atrium in one child and from the right renal vein to the right atrium with extensions into the hepatic and lumbar veins in another. After nephrectomy, the atria and inferior vena cava were opened and the tumor extracted under direct vision. Both patients are well.

From 1976 to 1986 inclusive, 122 patients were cared for with Hirschsprung's disease. Sixteen of these were treated for total colonic aganglionosis, with or without small bowel involvement. The male to female ratio was 2.2:1. Two children died prior to definitive surgical therapy and two others were transferred following initial therapy. Twelve children underwent Martin's procedure with a 0% mortality rate and an 81.8% morbidity rate. This study would indicate, as do others, that even though the Martin procedure can safely be performed, the long-term results require close scrutiny. A re-evaluation of this procedure and its alternatives is necessary in order to improve long-term results.

Only a small number of ingested foreign bodies perforate the esophagus and even a smaller fraction migrate extraluminally with no symptoms. Both of these events are even rarer after coin ingestion. Between 1972 and 1984, three children (16 months to 5 years), who had unabating upper respiratory symptoms, were found to have ingested coins. In only one child could the time interval between ingestion and appearance of symptoms (3 years) be established, and in this child the diagnosis was delayed because of failure to x-ray the chest after an ingestion episode. Surgical evaluation included chest/neck films: tracheal and esophageal shadows were separated by the object and a soft tissue mass; esphagogram: deviation of the esophagus, irregularity of the lumen, and no leak or tracheoesophageal fistula (TEF) and esophagoscopy: mucosa was intact with no direct visualization of the coin. Treatment consisted of exploration: cervical, one; thoracic, two; localization: coin in extraluminal granulomatous soft tissue; removal: without resection of the soft tissue mass or esophagus, and drainage: penrose, one; chest tube, two. There was no morbidity or mortality from 1 to 13 years later. Though generally harmless, ingested coins are capable of penetrating the esophagus. Sporadic literature reports confirm that the clinical findings and operative results are typical of this seemingly intermediate stage between perforation with mediastinitis and perforation with TEF.

Primary hyperparathyroidism in the mother during pregnancy is known to result in a high rate of fetal complications; spontaneous abortions, still births, and neonatal tetany occur in excessive incidence. To understand the pathophysiology of neonatal hypocalcemia that accompanies this disorder, transplacental calcium dynamics were studied in female sheep during the last trimester of pregnancy and in their fetal lambs after hysterotomy. Calcium ion was shown to move rapidly across the placenta. However, this organ blocked the passage of both parathyroid hormone and calcitonin from the maternal and to the fetal circulations. Our studies support the hypothesis that in primary hyperparathyroidism maternal hypercalcemia results in fetal hypercalcemia, which leads to suppression of fetal parathyroid gland function. In such a situation, neonatal hypocalcemia would occur after birth when maternal calcium flow is interrupted. Parathyroidectomy performed in the mother, especially during the second trimester of pregnancy when operation is safest, would break this cycle and permit normal serum calcium homeostasis in the fetus.

In the 6-year period between 1977 and 1982 inclusive, 75 newborn infants with congenital diaphragmatic hernia of Bochdelek underwent corrective surgery during the first 24 hours of life. A total of 40 infants (53%) survived. Beginning in January 1980, a standardized approach to care including early use of mechanical ventilation and paralysis with pancuronium as well as dopamine use prior to any Priscoline infusion, was instituted. To determine whether these approaches improved outcome, term infants without malformations from the years 1977 to 1979 were compared with a similar group treated after institution of standardized care between 1980 and 1982 inclusive. The infants were comparable in all respects, but survival improved from 45% to 82% between the two periods (P less than 0.03). There was an associated decrease in the incidence of pneumothorax (45% in first period; 14% in second period) paralleled by a concomitant increase in pancuronium use (18% and 85%, respectively). Although factors responsible for the improved survival are multifactorial these data indicate the detrimental effect of pneumothorax on outcome and the beneficial effect of a standardized approach to care using conventional intensive care techniques.

Surgical treatment for pulmonary interstitial emphysema (PIE) has been reported with increasing frequency. We have done pulmonary lobectomies in 14 neonates with the localized form of PIE. This type of treatment was successful in 11 patients. Two patients expired in the hospital and one showed no improvement. Another six very compromised patients with diffuse PIE were treated during the same period with multiple visceral pleurotomies. Only one survived. Infants with diffuse PIE are usually poor surgical candidates, while those with acquired lobar emphysema (ALE) have been treated successfully with lobectomies.

A study was designed and carried out to determine if the canine model of hypertrophic pyloric stenosis is applicable to other species and to demonstrate the transplacental passage of gastrin. Results of the study show that (1) pentagastrin does not induce hypertrophic pyloric stenosis in the rabbit; (2) human gastrin does not cross the canine placenta, and (3) gastrin has no documented and little inferred role in the etiology of CHPS.

Fasting serum gastrin concentrations were determined by radioimmunoassay for 124 infants and children free of gastrointestinal disease. Values for the entire group ranged from 1.1 to 167.9 pg/ml (mean, 32.3 pg/ml). Mean serum gastrin levels for children who fasted eight or more hours were 22.5+/-23.9 pg/ml while the mean serum gastrin levels for children who fasted four to eight hours ranged from 42.4+/-33.9 pg/ml to 59.2+/-49.6 pg/ml. The mean serum gastrin levels varied inversely with body surface area among children who fasted the same length of time.

Ten consecutive children with clinical evidence of splenic rupture underwent surgical exploration. In eight patients, all or part of the spleen could be preserved. The two patients requiring splenectomy had associated injury to the tail of the pancreas. Surgical techniques employed to preserve the injured spleen were those in common use to repair equivalent hepatic or renal injuries. There was no morbidity or mortality associated with the procedure. Splenic salvage protects the child from increased susceptibility to sepsis associated with splenectomy.

Examination of the records of 378 children with intussusception at our institution revealed that 29 cases were caused by an identifiable intestinal lesion. A Meckel's diverticulum was the causative agent in 21 children, all of whom were under 2 yr of age. A previously undiagnosed ileal lymphosarcoma produced the intussusception in six other children, all between 6 1/2 and 9 yr of age. Our experience indicates that any child over 6 yr of age with the clinical findings of colicky abdominal pain, bloody stools, and a palpable mass plus the radiographic evidence of intussusception must be considered to have ileal lymphosarcoma until proven otherwise. Hydrostatic reduction of the intussusception must be accompanied by extensive small bowel reflux of barium in order to effectively rule out a small intestinal lesion. If this is not accomplished, surgery should be planned with the suspicion that a malignancy may be present. If this suspicion is confirmed by frozen section, the operation procedure should include wide surgical excision of the lesion along with the regional lymph nodes.
