Ocular injuries in children after major trauma.

OBJECTIVE: To determine the variety of ocular injuries sustained by children during major trauma. SUBJECTS AND METHODS: The pediatric trauma registry of The Children's Hospital in Denver, Colorado, was surveyed for children with ocular injuries and an Injury Severity Score higher than 15. The injuries were tabulated and correlated with mechanisms of injury to determine identifiable injury patterns. RESULTS: In a pediatric trauma center, ocular injuries were nearly twice as frequent among children with major trauma (Injury Severity Score > 15). Two-thirds of the children with an Injury Severity Score higher than 15 had been involved in a mishap with a motorized or a nonmotorized vehicle. Ocular injuries in children with an Injury Severity Score higher than 15 were characterized by fracture of the surrounding bony structures and contusions. Children with an Injury Severity Score higher than 15 had 50% to 80% fewer open wounds of the ocular adnexa and eyeball than did children with an Injury Severity Score of 15 or lower. The one optic nerve injury and two-thirds of the other ocular cranial nerve injuries occurred in children with an Injury Severity Score higher than 15. CONCLUSIONS: Serious ocular injury should be suspected in children involved in a motor vehicle accident who have an Injury Severity Score higher than 15 and fractures of the surrounding bony structures, contusions, or both. Absence of an open wound of the ocular adnexa or eyeball does not eliminate the possibility of serious ocular injury.

Delayed near-fatal hemorrhage after Nuss bar displacement.

A novel case of Nuss bar displacement with near-fatal hemorrhage 3 months after insertion and 3 weeks after unreported bar movement is presented. Salient features of presentation, evaluation, and treatment are described including how to divide the bar from an intrathoracic approach.

Spectrum of ocular injuries in children with major trauma.

BACKGROUND: Few studies document the variety of ocular injuries encountered in children after major trauma. This study was performed to determine the type and frequency of ocular injuries in a large population of children with major trauma. METHODS: All children with ocular and adnexal injuries (n = 7497) among 96,879 children registered in the National Pediatric Trauma Registry (NPTR) were analyzed. Children were stratified for Injury Severity Score (ISS is a method for categorizing patients with multiple injuries in which an ISS > 15 is considered major trauma), age, sex, injury, protective restraint, vision threatening injury, and basilar skull fracture. RESULTS: Nearly 8% of the children in the NPTR sustained an ocular injury. These children had one or more injuries to one or both eyes and/or the ocular adnexa for an average of 1.3 ocular injuries per child. Three-fourths (75%) of the children with an ocular injury had an ISS < or = 15 and one-fourth (25%) had an ISS > 15. Among children with an ISS > 15 the most common injuries were orbital wall fracture (59%) and contusion of the eye and ocular adnexa (18%). Among these same children with an ISS > 15, the percent of orbital wall fractures, injuries to the optic nerve, and injuries to the other ocular cranial nerves doubled while the percent of basilar skull fractures tripled when compared with children with an ISS < or = 15. Penetrating injuries of the globe were significantly lower in children with an ISS > 15 than in children with an ISS < or = 15. Over 70% of the children with an eye injury and an ISS > 15 sustained injury in an accident involving a motorized or non motorized vehicle, and over 75% of those who could have been restrained, were not restrained. CONCLUSIONS: Children with an ocular injury sustained during major trauma (ISS > 15) are more likely to have a basilar skull fracture, orbital wall fracture, and a contusion of the eye and/or the ocular adnexa as compared with children with ISS < or = 15. Children with any of these injuries sustained during major trauma should be afforded prompt ophthalmologic evaluation to uncover injury to components of the visual system.

Efficacy of left thoracoscopy and blunt mediastinal dissection during the Nuss procedure for pectus excavatum.

BACKGROUND/PURPOSE: The minimally invasive Nuss procedure is emerging as the preferred technique for repair of pectus excavatum. Original methods of pectus bar placement have been modified to improve safety and efficacy and avoid cardiothoracic complications. The currently reported modifications to facilitate retrosternal pectus bar placement include routine use of right thoracoscopy or a subxiphoid incision. The purpose of this article is to describe additional modifications of the Nuss procedure to improve safety and efficacy. METHODS: A retrospective analysis was performed on 51 patients who have had a thoracoscopic-assisted Nuss procedure at The Children's Hospital, Denver, Colo, between 1999 and 2002. Technical modifications included patient positioning, routine use of left thoracoscopy, and an Endo-kittner. RESULTS: Fifty-one patients have successfully undergone the Nuss procedure using the new modifications. Surgical time ranged from 45 to 120 minutes. There have been no intraoperative or postoperative bleeding complications. There have been 2 large pneumothoraces requiring needle thoracenteses in the operating room before extubation. No chest tubes were required postoperatively. Subjectively, all patients have been satisfied with their surgical correction. Average length of hospital stay was 4 to 6 days. CONCLUSIONS: By using left chest thoracoscopy and Endo-kittner dissectors, the risk of cardiothoracic injury can be eliminated. Moreover, other methods to ensure safe substernal dissection are unnecessary.

Are patients who have had a tracheoesophageal fistula repair during infancy at risk for esophageal adenocarcinoma during adulthood?

The authors present a case of a 46-year-old woman who had esophageal adenocarcinoma after having had a tracheoesophageal fistula (TEF) repair as an infant. A Medline search, which identified 2 other patients in the world literature who developed esophageal cancer (squamous cell carcinoma [J Pediatr Surg 36(4) (2001) 629-630] and adenocarcinoma [J Pediatr Surg 24(8) (1989) 741-744]) after TEF repair, was performed. As such patients reach middle age, it is possible that they are at increased risk for the development of esophageal cancer. Practitioners should be aware of the possibility of increased risk in this population and perhaps the need for a study to screen patients who have had a TEF repair to assess the incidence of cancer.

Gastrostomy revision: incidence and indications.

BACKGROUND/PURPOSE: Although quite reliable, gastrostomy may require revision. However, there are no reports in the literature specifically delineating identifiable risk factors or circumstances that lead to gastrostomy revision in children with gastrostomy. The purpose of this report was to determine the rate of revision and correlate any factors that may lead to revision. METHODS: A retrospective chart review was performed on 1,042 children who underwent gastrostomy at The Children's Hospital, Denver, Colorado, between 1992 and 2002. Charts of children who underwent gastrostomy were reviewed for pertinent clinical factors and compared with those who required gastrostomy revision. RESULTS: Of the 1,042 children, who had gastrostomies, 67 revisions were required in 61 children (6%). Of the many possible factors that could have had an influence on the revision rate, only fundoplication, percutaneous endoscopic gastrostomy (PEG), migration of the gastrostomy site, and time correlated with the need for gastrostomy revision. CONCLUSIONS: Parents should be made aware that there is a 6% chance that their child's gastrostomy may need revision and that the need for revision may increase with PEG, initial construction before 18 months of age, and the advancing age of the gastrostomy. Surgeons should avoid placing the gastrostomy near the costal margin, making a large gastrostomy exit tract through the abdominal wall and inserting a gastrostomy into the nutritionally depleted pulmonary stressed neurologically challenged child without first attempting to improve the child's nutritional status.

Analysis of factors affecting the spontaneous closure of a gastrocutaneous fistula.

BACKGROUND/PURPOSE: Few reports have documented the rate of persistence of a gastrocutaneous fistula (GCF) after gastrostomy removal or the reason for the persistence of a GCF. The purpose of this report was to analyze a large group of pediatric patients with a persistent GCF to determine the rate of persistence and any factors that correlate with the persistence of a GCF. METHODS: This was a retrospective review of 1,042 children from The Children's Hospital, Denver, Colorado who had a gastrostomy constructed between 1992 and 2002. The charts of all children with a persistent GCF after gastrostomy catheter removal were analyzed for correlation between 13 clinical parameters and the persistence of a GCF. RESULTS: There were 150 children with a persistent GCF for an incidence of 34%. Time elapsed between the creation of the GCF and removal of the gastrostomy appliance (< or =8 months versus >8 months) was the only parameter that showed any correlation with persistence of a GCF (P <.05). None of the other parameters studied showed any conclusive correlation with persistence of a GCF. CONCLUSIONS: Time was the only factor that determined whether a surgically created GCF would persist after removal of a gastrostomy appliance.

Percutaneous central access in patients younger than 5 years: size does matter.

PURPOSE: The purpose of this study was to determine, in a pediatric population less than 5 years of age, which size catheter is ideal for central venous access via the subclavian and internal jugular vein based on the children's age, weight, and height. METHODS: This was a retrospective chart review of children less than 5 years of age at The Children's Hospital in Denver, Colorado who underwent subclavian or internal jugular central venous catheter placement from January 1, 1998 through December 31, 2001. Age, height, weight, primary disease, access site, type of central venous catheter, size of central venous catheter, and complications were recorded. Age, weight, and height were stratified and compared with catheter size to determine any correlation between age, weight, height, and complications. RESULTS: There were 430 central venous catheters placed via the subclavian or internal jugular vein in 331 patients less than 5 years old. One hundred ninety-five catheters (45.4%) were less than 6F in size, and 235 (54.6%) catheters were > or =6F in size. Children, who were between 0.5 and 0.99 years old, 5 to 7.49 kg in weight, 7.5 to 9.99 kg in weight, and 60 to 74.9 cm in height had higher complication rates (P <.05) when catheters > or =6F were inserted. Children who were greater than 1 year of age, greater than 10 kg in weight, and longer than 75 cm in height did not experience a significant difference (P >.05) in complications versus catheter size. CONCLUSIONS: The choice of central venous catheter size should be predicated, not only on the primary disease, but also on the child's age, weight, and height. Insertion of central venous catheters larger than 6F in children less than 1 year of age, less than 10 kg in weight, or less than 75 cm in height, was associated with higher complications compared with other settings.

Gastric prolapse through a gastrostomy tract.

BACKGROUND/PURPOSE: Few reports have documented the incidence or the characteristics of children with gastric prolapse through a gastrostomy tract. The purpose of this report was to determine the incidence of gastric prolapse through a gastrostomy tract and to identify the salient features associated with gastric prolapse. METHODS: This was a retrospective review of 1,042 children from The Children's Hospital, Denver, CO who had a gastrostomy constructed for enteral access between 1992 and 2002. The charts of children who had gastric prolapse through the gastrostomy tract were scrutinized to obtain a profile of the children who had prolapse, and 14 parameters were analyzed for correlation with the incidence of this complication. RESULTS: Thirteen children had gastric prolapse through the gastrostomy tract for an incidence of gastric prolapse of 1.2%; 5 children had recurrent gastric prolapse through a gastrostomy tract for an incidence of recurrent gastric prolapse of 0.5%. Gastric prolapse occurred more often in children with ventilator dependence (31%), poor nutrition (54%), and neurologic disorders (58%). Gastrostomy devices with both ends fixed and rigid were associated with gastric prolapse (2.7%) more often than devices with only 1 end fixed and rigid (0.6%). Laparoscopic gastrostomy was associated with gastric prolapse and recurrent gastric prolapse more often than other gastrostomy construction techniques. CONCLUSIONS: Children with poor nutrition, ventilator dependence, a neurologic disorder, a gastrostomy device with both ends fixed and rigid, and/or a laparoscopic gastrostomy, were prone to gastric prolapse.

Recurrent inflammatory pseudotumors in children.

BACKGROUND/PURPOSE: pulmonary (PPT) and extrapulmonary pseudotumors (EPPT) are uncommon benign tumors, which, in general, do not recur after complete resection. Recurrence rates for both types of pseudotumors are undocumented in a large population of children, and the salient features of potential recurrences are unspecified. METHODS: This is a report of 15 children with PPT and EPPT; 3 children had a recurrence. These pseudotumors recurred despite adequate primary resection of all gross disease at first presentation. The literature was reviewed to determine rate of recurrence for PPT and EPPT and also to document features common to recurrent pseudotumors. RESULTS: Overall recurrence rate for pseudotumors was 14%. PPT and EPPT, which were not confined to a single organ, had a high chance of recurrence (46% and 30%, respectively) compared with PPT and EPPT, which were confined to a single organ (1.5% and 8%, respectively). Recurrences have appeared between 3 months and 7 years. Intraabdominal EPPT accounts for more than 75% of the EPPT recurrences. CONCLUSIONS: PPT and EPPT recur more frequently than anticipated. All pseudotumors, which on initial presentation extend beyond the confines of a single organ, have a high chance of recurrence despite what appears to be adequate resection. Children with pseudotumors that extend beyond a single organ, require frequent postoperative evaluation for recurrence and may be candidates for chemotherapy or radiotherapy at the time of initial resection.

Management of giant omphalocele in a premature low-birth-weight neonate utilizing a bedside sequential clamping technique without prosthesis.

Management of giant omphalocele in a full-term neonate is a challenging clinical situation. Even more challenging is giant omphalocele in a premature low-birth-weight infant. The authors describe a successful staged noninvasive technique for the management of giant omphalocele in a premature, low-birth-weight neonate without the use of prosthetic material until delayed primary closure could be attempted.

Is a routine chest x-ray necessary for children after fluoroscopically assisted central venous access?

PURPOSE: The aim of this study was to determine in a pediatric population whether a routine chest x-ray after central venous access is necessary when the central venous catheter is placed with intraoperative fluoroscopy. METHODS: This was a retrospective review of the charts of all patients at Children's Hospital in Denver, Colorado who underwent subclavian or internal jugular central venous catheter placement from January 1, 1998 through December 31, 2001. Age, sex, primary reason for access, access site, number of venipuncture attempts, type of catheter, intraoperative fluoroscopy results, chest x-ray results, location of the tip of the catheter, and complications were analyzed. RESULTS: There were 1,039 central venous catheters placed in 824 patients, 92.6% in the subclavian vein and 7.4% in the internal jugular vein. There were 604 (58.1%) children who had both fluoroscopy and a postprocedure chest x-ray, there were 308 (29.6%) who had only fluoroscopy, there were 117 (11.3%) who had only a postprocedure chest x-ray, and there were 10 (1.0%) who had neither fluoroscopy nor chest x-ray. On completion of the procedure, there were 12 (1.1%) children with misplaced central venous catheters, only 1 (0.1%) when intraoperative fluoroscopy was used. There were 17 (1.6%) complications; 9 (0.9%) were pulmonary (pneumothorax, hemothorax, or an effusion). All children with pulmonary complications experienced clinical signs and symptoms suggestive of the complication after their central venous catheter insertion but before their postprocedure chest x-ray. CONCLUSIONS: The number of complications encountered in children who had central venous access of the subclavian vein or internal jugular central vein with intraoperative fluoroscopy was infrequent, the number of misplaced catheters was minimized with intraoperative fluoroscopy, and all children with pulmonary complications showed clinical signs suggestive of pulmonary complications before postoperative chest x-ray. Therefore, children who have had central venous access of the subclavian and internal jugular vein with intraoperative fluoroscopy do not appear to require a routine chest x-ray after catheter placement unless clinical suspicion of a complication exists.

Spectrum of anorectal anomalies in pygopagus twins.

BACKGROUND/PURPOSE: The literature lacks a concise description of the anorectal anomalies encountered in pygopagus twins. METHODS: This is a retrospective literature review of 34 pygopagus twins highlighting their anorectal malformations. RESULTS: Overall pygopagus twins represent 17% of all conjoined twins. Live-birth pygopagus twins are more commonly female (86%), whereas stillborns are commonly male (80%). Half of the twins had nonfused rectums, and half had fused rectums. The nonfused had 2 rectums (80%) or one rectum and one rectovaginal fistula (20%). The fused had high (46%) or low (54%) rectal junctions. All reported living male pygopagus twins have had nonfused rectums. All can be managed applying the principles of posterior sagittal anorectoplasty. CONCLUSIONS: In general, live-born male pygopagus twins are likely to survive with a nonfused rectum and good bowel function, whereas live-born female pygopagus twins have a good chance of surviving with a fused rectum (high or low), which requires appropriate operative reconstruction.

Increased CT scan utilization does not improve the diagnostic accuracy of appendicitis in children.

BACKGROUND/PURPOSE: Appendicitis continues to present a diagnostic dilemma in children of all ages leading to increased utilization of radiographic studies. Focused computed tomography (CT) scanning has become the diagnostic test of choice in many hospitals. The purpose of this study was to critically evaluate the use of radiographic studies for the evaluation of acute appendicitis in children and to determine if diagnostic accuracy has improved. METHODS: Children undergoing appendectomy for acute appendicitis were reviewed from 1997 to 2001. Diagnostic workup (CT scan, ultrasound [US], or no radiographic study) was recorded as were the final pathology results. RESULTS: Six hundred sixteen appendectomies were performed. Mean age was 10.4 +/- 4.1 years, and 60% were boys. Overall, 184 children (30%) underwent CT scanning, 104 (17%) had US performed, and 310 (50%) had no radiographic study (18 patients had both CT and US performed). A pathologically normal appendix was removed in 7% (14 of 202) of CT patients, 11% (14 of 122) of US patients, and 8% (26 of 310) of patients without a study. The frequency of CT scanning increased from 1.3% of all children in 1997 to 58% in 2001, whereas utilization of US decreased from 40% to 7%. Over the same period, the overall negative appendectomy rate did not change significantly from 8% to 7%. CONCLUSIONS: With increased utilization of focused CT scanning, the negative appendectomy rate has remained unchanged. History and physical examination by an experienced surgeon is as accurate as CT in correctly diagnosing acute appendicitis in children.

Magill forceps extraction of upper esophageal coins.

BACKGROUND/PURPOSE: This study demonstrates a minimally invasive technique for upper esophageal coin extraction. METHODS: A retrospective review was conducted of 36 children who had upper esophageal coins extracted using a Magill forceps. RESULTS: All coins were removed without complication in approximately 45 seconds (33 on the first attempt, 3 on the second attempt). CONCLUSIONS: This technique minimizes instrumentation of the esophagus and is highly successful at removing coins lodged at or immediately below the level of the cricipharyngeus muscle.

Is hypotension a reliable indicator of blood loss from traumatic injury in children?

BACKGROUND: Traditional surgical teaching stresses that hypotension is an indicator of loss of circulating blood volume. The purpose of this study is to critically evaluate hypotensive injured children for evidence of a hemorrhagic insult. METHODS: Over a 2-year period, data were collected prospectively from children injured via a blunt mechanism. Systolic blood pressure (SBP) was recorded in the field and on arrival to the emergency department. RESULTS: In all, 194 injured children were identified as hypotensive. Only 82 (42%) had identifiable injuries to account for significant volume loss. Children 0 to 5 years old had a 61% incidence of isolated head injury (46 of 76) and only a 34% incidence of hemorrhagic insult (26 of 76). Children 6 to 12 years old had a 31% incidence of isolated head injury (22 of 72) and a 52% incidence of hemorrhagic insult (38 of 72). Finally, patients more than 12 years old had a 33% incidence of isolated head injury (15 of 46) and a 39% incidence of hemorrhagic insult (18 of 46). CONCLUSIONS: Hypotension should not be viewed only as a potential marker of loss of circulating volume, but also as a possible indicator of head injury in young trauma victims.
