Reduced hospitalization cost for patients with pectus excavatum treated using minimally invasive surgery.

BACKGROUND: Currently, few data exist regarding the relative costs associated with open and minimally invasive pectus excavatum repair. The aim of this study was to compare the surgical and hospitalization costs for these two surgical techniques and to identify factors responsible for cost differences. METHODS: A retrospective review of hospital charts, patient and parent questionnaires, and hospital accounting records was performed for 68 patients who underwent surgical correction of pectus excavatum between June 1996 and December 1999. RESULTS: In this series, 25 patients underwent open repair, whereas 43 patients underwent minimally invasive repair of pectus excavatum (MIRPE). The patient ages ranged from 4 to 19 years. The average ages for open repair (12 years) and MIRPE (11 years) did not differ significantly. As compared with open repair, MIRPE was associated with a 27% lower overall cost of hospitalization ( p < 0.05). The operating room costs were 12% higher for the patients who underwent MIRPE ( p < 0.05). The mean operative time for open repair was 3 h 15 min, whereas MIRPE required 1 h 10 min ( p < 0.001). The hospital stay for open repair averaged 4.4 days, as compared with 2.4 days for MIRPE ( p < 0.001). In contrast to other published series, the postoperative analgesia after MIRPE in this series consisted of narcotics, ketorolac, and methocarbamol. No patient received epidural analgesia, regardless of the repair technique selected. The postoperative complication rate was 4% in the open group and 14% in the MIRPE group. Most of the patients treated with either open or MIRPE reported postoperative oral narcotic usage for 2 weeks or less and returned to routine activities within 3 weeks. The patients and parents alike reported good to excellent overall outcomes in 85% or more of the open repair cases and 90% or more of the MIRPE cases. CONCLUSIONS: These data demonstrate for the first time that the use of an alternate pain management strategy including, narcotics, NSAIDs, and methocarbamol, but without epidural catheters, results in reduced hospital length of stay and decreased overall hospitalization costs for MIRPE, as compared with open pectus repair. This cost benefit was achieved without compromising pain management or patient satisfaction with surgical care.

Breast conservation in the treatment of breast cancer: community-based experience.

BACKGROUND: Results of large, randomized studies in the 1980s established wide excision and radiation as an accepted breast cancer treatment approach. We evaluated our initial results with this treatment in the community setting. METHODS: We evaluated the frequency and outcome of breast conservation treatment in 303 women with invasive ductal carcinoma from 1985 to 1995. RESULTS: The frequency of breast conservation treatment increased from 9% during 1985 to 1989 to 24% during 1990 to 1995. With a median follow-up of 4.7 years, there were 19 (6%) ipsilateral recurrences. Metastatic disease occurred in 23 patients (8%). Overall 5-year survival was 95%, and 5-year recurrence-free survival was 90%. Twelve patients died of breast cancer. CONCLUSIONS: Increased use of breast conservation in our community practice parallels the national trend, with similar treatment results. Our findings suggest the successful integration of research-proven innovations into community practice.

The April 8, 1998 tornado: assessment of the trauma system response and the resulting injuries.

BACKGROUND: On April 8, 1998, an F5 tornado touched down in two counties of Alabama producing a wide path of destruction. The presence of a regional trauma system in this area presents an opportunity to evaluate the effectiveness of the system in responding to the victims of this natural disaster. METHODS: Emergency room logs and the regional trauma system database were searched for all patients treated for injuries sustained from the tornado, and medical records were reviewed for demographic information, mode of transportation to hospital, injuries, treatment, and outcome. Fatalities were identified by means of the coroner's office. RESULTS: A total of 224 patients were evaluated at nine area hospitals, of whom 63 (28%) required admission. There were 32 deaths: 30 persons were dead at the scene, and 2 patients subsequently died at Level I trauma centers. Among patients with nonfatal injuries, 39% were managed at Level I facilities, 46% at Level III facilities, and 15% at nontrauma facilities. Forty patients (55%) seen at Level I facilities required admission compared with 15 patients (17%) at Level III facilities and 8 patients (29%) at nontrauma facilities; Level I facilities also had the highest Injury Severity Score. Of patients requiring admission, 83% were transported by emergency medical services; these patients also had the highest Injury Severity Score. CONCLUSION: The regional trauma system facilitated appropriate and efficient triage to system hospitals, routing the most severely injured patients to the Level I centers without overwhelming them with the more numerous, less severely injured patients.

Clinical information systems.

Clinical information systems are the computer and information systems used by health care personnel to facilitate patient care. These systems have evolved from financial systems to true patient care systems with variable levels of functionality. Early systems provided laboratory and radiology results, and modern systems now provide copies of the radiology images and decision support for therapeutic orders. The rapidly changing technological infrastructure has created barriers to implementation of the electronic medical record, while coding schemes continue to be refined to enable data access and aggregate data analysis. Further refinement of clinical information systems is required before the potential value of these systems is realized in the clinical management of patients.

Evidence-based practice in pediatric surgery.

BACKGROUND/PURPOSE: The current medical environment demands the provision of quality healthcare at an affordable cost. Both payors and regulators are committed to lowering cost through initiation of best practice strategies that include practice guidelines, clinical pathways, and standards of care. The only practical way to join this debate is through the use of objective, unbiased clinical data. This study was undertaken to review the current state of the pediatric surgery literature and its value in determining best clinical practice. METHODS: The National Library of Medicine Medline database was accessed using the Ovid Internet client software. All references, abstracts, and keyword indexes from the core pediatric surgery literature, the Journal of Pediatric Surgery, the European Journal of Pediatric Surgery, Pediatric Surgery International, Zeitschrift fur Kinderchirurgie, and Seminars in Pediatric Surgery were downloaded and reviewed. Search criteria were defined to identify prospective, randomized, controlled studies. References were then categorized as case reports; retrospective case series; prospective case series; randomized, controlled studies; laboratory studies; review articles; or miscellaneous studies. RESULTS: As of March 1, 1998, there are 9,373 references, excluding citations of letters or comments, contained in the core pediatric surgery literature, as provided through Medline. Of these, 485 were identified as studies for review, possible prospective case series or prospective, randomized, controlled studies. After review, 34 studies (0.3%) were classified as prospective, randomized, controlled studies, whereas 139 (1.48%) were classified as prospective studies. There were 3,241 (34.6%) case reports, 5,619 (59.9%) retrospective case series, 1,109 (11.8%) laboratory studies, 195 (2.1%) review articles, and 36 (0.3%) miscellaneous studies that did not fit into other categories. When analyzed by decade of publication, prospective studies and prospective, randomized, controlled studies (n = 173) numbered 103 in the 1990s, 63 in the 1980s, and seven in the 1970s. CONCLUSIONS: There is a paucity of scientifically rigorous data on which to base clinical practice in pediatric surgery. The increasing numbers of prospective, case-controlled studies or the more sound prospective, randomized, controlled trials in the 1990s suggests that pediatric surgeons are aware of the need to generate unbiased data to support current clinical practice and the development of practice guidelines. Limitations exist in conducting prospective, randomized, controlled trials because of the rare nature of many pediatric surgical conditions and the lack of clinical "equipoise" over available treatment options. The authors encourage the use of multiinstitutional trials and the prospective, randomized, controlled study methodology to develop data that can be used to guide clinical practice in our evolving healthcare environment.

Current surgical management of congenital diaphragmatic hernia: a report from the Congenital Diaphragmatic Hernia Study Group.

BACKGROUND: Repair of congenital diaphragmatic hernia (CDH) has changed from an emergent procedure to a delayed procedure in the last decade. Many other aspects of management have also evolved since the first successful repair. However, most reports are from single institutions. The lack of a large multicenter database has hampered progress in the management of congenital diaphragmatic hernia (CDH) and makes determination of the current standard difficult. METHODS: The CDH study group was formed in 1995 to collect data from multiple institutions in North America, Europe, and Australia. Participating centers completed a registry form on all live-born infants with CDH during 1995 and 1996. Demographic information, data about surgical management, and outcome were collected for all patients. RESULTS: Sixty-two centers participated, with 461 patients entered. Overall survival was 280 of 442 patients (63%) where survival was recorded. The defect was left-sided in 78%, right-sided in 21%, and bilateral in 1%. A subcostal approach was used in 91% of patients, with pleural drainage used in 76%. A patch of some kind was used in just over half (51%) of the patients, with polytetrafluoroethylene being the most commonly used material (81%) in those patients with a patch. The mean surgical time was 102 minutes, with an average blood loss of 14 mL (range, 0 to 500 mL). The overwhelming majority of patients underwent repair between 6:00 AM and 6:00 PM (289 of 329, 88%). Nineteen percent of patients had surgical repair on extracorporeal membrane oxygenation (ECMO) at a mean time of 170 hours into the ECMO course (range, 10 to 593 hours). The mean age at surgery in patients not treated with ECMO was 73 hours (range, 1 to 445 hours). CONCLUSIONS: The multicenter nature of this report makes it a snapshot of current management. The data would indicate that prosthetic patching of the defect has become common, that after-hours repair is infrequent, and that delayed surgical repair has become the preferred approach in many centers. Furthermore, the mean survival rate of 63% indicates that despite decades of individual effort, the CDH problem is far from solved. This highlights the need for a centralized database and cooperative multicenter studies in the future.

Gluteus maximus augmentation for the treatment of fecal incontinence.

Fecal incontinence is a devastating problem for school-aged children and adults. Medical and biofeedback therapies are unsuccessful in most patients who have severely defective internal and external sphincters. Continued fecal incontinence frequently leads to social isolation and withdrawal. Gluteus maximus augmentation of the sphincter mechanism is one surgical method for treating fecal incontinence. The authors present their results with gluteus maximus augmentation of the anal sphincter and describe patient selection criteria. From 1992 through 1996, seven patients underwent gluteus maximus augmentation of the anal sphincter for fecal incontinence. Six of these patients were children 5 to 6 years of age who had major deficiencies of their anorectal sphincter demonstrated by manometry. One patient was a 56-year-old adult woman who had acquired idiopathic fecal incontinence. Four of the six children (67%) had imperforate anus and two had cloacal anomalies (33%). The augmentation was performed in three stages. A sigmoid-end colostomy with a Hartman's pouch was followed 1 month later by rotation of a portion of the gluteus maximus for anorectal sphincter augmentation. A colostomy take down was performed 2 to 4 months later. All patients underwent dilatation after sphincter augmentation and were taught muscle exercises for using their neosphincter during the period before colostomy take down. Four of six children and the adult are continent postoperatively (71%). Both patients who remain incontinent are unable to sense rectal distention clinically or on anal manometric analysis but have excellent voluntary sphincter tone. Fecal incontinence can be successfully treated with gluteus maximus augmentation in carefully selected patients. Patients unable to sense rectal distension are unlikely to benefit from this procedure. The presence of a rectal reservoir and a skin-lined anal canal also appear to be important in attaining fecal continence.

Pediatric surgeons on the Internet: a multi-institutional experience.

An estimated 24 million people, or 11% of the North American population over 16 years of age, use the Internet. An estimated 40% of households have computers, and 37 million people have Internet access. The experience of three pediatric surgery Internet sites are reviewed to evaluate current practices and future potential of the Internet to practicing pediatric surgeons. The sites reviewed are the Pediatric Surgery Bulletin Board System (BBS), the Pediatric Surgery List Server, and the Pediatric Surgery Website. Statistics were collected at each site to characterize the number of users, traffic load, topics of interest, and times of peak use. There are currently 79 subscribers to the Pediatric Surgery BBS and 100 subscribers to the Pediatric Surgery List Server. The average user of the BBS is a young man who has placed an average of 52 calls to the BBS since joining. There have been 1413 Internet electronic mail messages sent. Twenty-five percent of the traffic has been related to clinical problems and 5% to research, teaching, and career issues. Traffic at this site has been increasing exponentially with most of the dialogue concentrated on clinical issues and problem cases. In a 3-month period the Pediatric Surgery Website received 16,270 hits. The most commonly accessed areas include an electronic mail directory, case studies, the job board, information on the pediatric surgical residency, and information on upcoming meetings. Pediatric surgeons are exploring the Internet and using available pediatric surgery resources. The scope of professional information available to pediatric surgeons on the Internet is still limited but is increasing rapidly. The Internet will impact the way physicians practice medicine through education and communication.

Pediatric cervical spine injury: a three-year experience.

BACKGROUND: Traumatic injuries of the cervical spine are uncommon in pediatrics. Children less than 8 years of age are reported to have "exclusively" upper cervical injuries. Recent experience at The Children's Hospital of Alabama (TCHA) challenged both of these notions. METHODS: A concurrent retrospective chart review of all cervical spine injuries treated at TCHA between January 1, 1992 and December 31, 1994 was performed. Data collected included patient demographics, date and time of injury, mechanism and site of injury, presence of associated injuries, clinical management, and outcome. RESULTS: Thirty-four patients with cervical spine injuries were seen at TCHA in the 36-month study period. The leading mechanism of injury was motor vehicle crashes (23/34 or 68%). Head injuries were associated with cervical spine injury in 53% of patients. Of the 20 patients aged 8 years or less, 10 (50%) had "low" cervical spine injuries (below C4). Overall mortality was 41% (14/34). Of the 15 vehicle occupants, 12 were unrestrained or inappropriately restrained. Two of those appropriately restrained were young school-aged children in lap-shoulder belts who sustained isolated cervical spine injuries. CONCLUSIONS: 1. The number of pediatric cervical spine injuries in our institution appears to be increasing. 2. Cervical spine injury in children less than 8 years of age are not exclusively confined to the region above C4. 3. Occurrence of cervical spine injuries despite lap-shoulder belt use suggests that efforts should be focused on refinement of motor vehicle restraint devices in young school-aged children.

Primary laparoscopic pull-through for Hirschsprung's disease in infants and children.

Between November 1993 and September 1994, 12 primary laparoscopic colon pull-through procedures were performed in infants and children. The patients' ages ranged from 3 days to 6 years. The primary diagnosis in all 12 patients was Hirschsprung's disease. All children had their operations without construction of preoperative or postoperative colostomy. Three 5-mm abdominal wall ports were used for access to the peritoneal cavity. The sigmoid colon and proximal rectum were mobilized laparoscopically. A submucosal sleeve was developed transanally to meet the dissection from above. The colon was then pulled down in continuity, divided above the transition zone, and secured to the anal mucosa 5 to 10 mm above the pectinate line. Mean postoperative stay was 4 days. Laparoscopic visualization provides clear delineation of pelvic structures even in small infants. Laparoscopic pull-through requires no more time than similar open procedures, averaging just over 2 hours. The morbidities associated with colostomy formation and closure and the inconvenience of colostomy care are avoided with a one-stage technique. These benefits combined with the advantages of minimally invasive surgery make primary laparoscopic pull-through a potential advance in the surgical treatment of Hirschsprung's disease.

Comparison of open and laparoscopic gastrostomy and fundoplication in 120 patients.

The rapid development and incorporation of minimally invasive surgical techniques has abruptly changed adult surgical practices. These minimally invasive procedures are now being successfully applied to pediatric surgical problems. The anticipated benefits of these techniques include less postoperative pain, quicker return of bowel function, shorter hospital stay, and lower hospital costs, with a quicker return to normal activity. This report compares the first 60 infants and children to undergo laparoscopic gastrostomy and/or fundoplication at our institution with the same number of patients that underwent these procedures in the traditional open fashion. The two groups were similar with respect to age, sex, concurrent illness, presenting symptoms, neurological status, and procedures performed. Patients in the laparoscopic group were found to have shorter mean hospital and postoperative stays and tolerated feeding earlier. The mean hospital stay was 13.8 days for the laparoscopic group versus 16.4 days in the open group. The mean postoperative stay was 6.8 days for the laparoscopic group versus 10.7 days for the open group. The mean postoperative day on which feeding was tolerated was 2.3 in the laparoscopic group versus 4.8 in the open group. Postoperative complications were similar between the two groups. These results seem to reflect the less traumatic nature of the laparoscopic procedures as compared with the open procedures. Laparoscopic fundoplication and gastrostomy is an attractive alternative to open fundoplication and gastrostomy in infants and children.

Sequential intestinal lengthening procedures for refractory short bowel syndrome.

Better understanding of the long-term delivery of parenteral nutrition (PN) in neonates and children has increased the survival for patients who have neonatal short bowel syndrome. Most infants with short bowel syndrome experience progressive enteral adaptation and are weaned from PN. This report describes the authors' clinical experience with nine infants and children who had refractory short bowel syndrome; single or sequential procedures were performed to lengthen the small bowel. Gut lengthening procedures used included a small bowel nipple valve constructed distally, to provide temporary partial obstruction and thereby induce dilatation and lengthening of the proximal small intestine (six patients). Bianchi's technique was used in three patients primarily and in six others after the bowel had been dilated and lengthened by the nipple valve. Kimura's gut lengthening technique was used in one patient after the small bowel had spontaneously become dilated subsequent to a Bianchi procedure. In all, 16 lengthening procedures were performed on the nine patients. Preoperatively, the nine patients tolerated less than 10% of their caloric intake enterally, with no evidence of improvement for a minimum of 6 months. Small bowel segments ranged from 6 to 92 cm originally and were increased an average of 2 1/2 times the original length. Two patients have been totally weaned from PN. For the patients whose lengthening procedure was performed more than 1 year ago, the percentage of enteral caloric intake averages 50%. One of the patients was profoundly impaired neurologically and was not resuscitated from an apneic episode. Another patient died in his sleep of unknown causes 1 year after intestinal lengthening.(ABSTRACT TRUNCATED AT 250 WORDS)

Predicting outcome following pulmonary resection in cystic fibrosis patients.

A small subset of cystic fibrosis (CF) patients develop pulmonary disease primarily limited to one lobe or lung segment requiring prolonged recurrent hospitalizations with intensive medical therapy. Although surgery has been advocated for patients who do not respond to medical therapy, very little is known about criteria for selection of patients who might benefit from resection of the involved parenchyma. In an attempt to further define criteria for pulmonary resection in these patients, we retrospectively reviewed our experience at Tulane Medical Center over the past 10 years. Fourteen patients with CF, ranging from 3 to 30 years of age, underwent 17 pulmonary resections. Indications for surgery were persistent lobar or pulmonary atelectasis and bronchiectasis requiring multiple hospitalizations and unresponsive to medical therapy (n = 13), bronchopleural fistula (n = 2), or hemoptysis not responding to medical therapy or selective embolization (n = 2). Thirteen lobectomies and four pneumonectomies were performed. Only two resections were on the left side and 11 right upper lobectomies were performed. Postoperative hospitalization ranged from 5 to 21 days (mean, 8.5 days). Preoperative pulmonary function tests showed widely divergent function in these patients. Forced expiratory volume (FEV1) ranged from 11% to 88% whereas forced vital capacity (FVC) ranged from 20% to 100% of predicted values. Oxygen saturation ranged from 86% to 99%. Although there was no significant difference in preoperative and postoperative FVC or O2 saturation, there was a significant (P less than .003) decrease in the postoperative FEV1. In the 12 surviving patients followed for at least 1 year, there was also a significant reduction (P less than .001) in the number of hospitalizations required due to pulmonary exacerbations from an average 2.2 admissions per year (range, 0.44 to 3.5 admissions per year) to 1.1 admissions per year (range, 0 to 8).(ABSTRACT TRUNCATED AT 250 WORDS)

Pseudocysts of the pancreas in children.

Sixteen children with pancreatic pseudocysts were treated from 1965-1988. Blunt trauma was the etiology of pseudocyst formation in 69 per cent of children with 50 per cent resulting from the abdomen impacting bicycle handlebars. Chronic pancreatitis is an uncommon cause of pseudocyst formation in children. Medical therapy is directed towards reduction of pancreatic stimulation and nutritional support, which are maintained through pseudocyst resolution or maturation. Pseudocysts spontaneously resolved in 25 per cent of patients. Complications occurred in 25 per cent during nonoperative management. Children may safely undergo internal drainage earlier than adults (3-4 weeks vs 6 weeks). Internal drainage by cystoenterostomy was curative in eight patients. Persistent fistula drainage developed for five weeks in one patient who had surgical external pseudocyst drainage. One patient required distal pancreatectomy for a transected pancreatic duct. Spontaneous resolution of psseudocysts while on medical therapy is more frequent in children than in adults, and major complications (abscess formation, hemorrhage, and fistula formation) are usually not encountered. Pseudocyst rupture is the major complication of conservative management. We had no pseudocyst recurrences and 11 of 12 children treated surgically were discharged home within ten days of operation.

Utility of the cervical spine radiograph in pediatric trauma.

To determine the utility of the routine cervical spine radiograph, we reviewed all cervical spine radiographs obtained in pediatric trauma patients over a 2 1/2-year period at the Childrens Hospital of Los Angeles. Records of patients admitted with a documented cervical spine injury over a 20-year period were also reviewed. One hundred eighty-seven children had at least one cervical spine radiograph. Forty-six patients (25 percent) required at least one repeat study in an attempt to see all 7 vertebrae. Thirty-eight children (20 percent) had a second radiograph and 8 patients had a third study, all of which showed no injury. There was only one fracture seen during the 2 1/2-year time period. Of the 16 children admitted over the 20-year period, only 3 sustained an injury below the fourth cervical vertebra (C4), and all were over 8 years of age. All patients with cervical spine injury were either comatose or had symptoms referable to the neck. We conclude that the routine cervical spine radiograph in pediatric trauma is a very low-yield test.

Percutaneous insertion of subclavian venous catheters in infants and children.

All attempts at subclavian venous catheterization by the Pediatric Surgery Service done during a one and one-half year period at the Children's Hospital of Los Angeles were prospectively studied. Catheterization was attempted in 107 patients with a mean age of 9.8 years. Cannulation of the vein was successful 89 times (71 per cent) with the major complications being arterial puncture (8.0 per cent), pneumothorax (2.4 per cent) and abnormal position (12.8 per cent). Fluoroscopy was a valuable adjunct when used, resulting in an 86 per cent success rate. The serious complication rate was similar between left and right-sided attempts, but more catheters were abnormally positioned during right-sided attempts (15.7 versus 5.2 per cent). Percutaneous insertion of subclavian venous catheters can be accomplished in infants and children with low morbidity. Cannulation of the left subclavian vein can be accomplished with a similar success rate and a lower malposition rate than the right side. Fluoroscopy is a useful tool to assist in the correct placement of the catheter.

Differentiation and treatment of hemangiomas and arteriovenous malformations.

Confusion exists about the differentiation of hemangiomas and other congenital vascular anomalies although they are the most common type of birth defect. During the past 10 years, these lesions have been reclassified on a pathophysiological basis which assists in defining their prognosis and treatment. Hemangiomas are broken down into three categories, those which affect the afferent capillary bed and may involute, efferent venous or lymphatic lesions which grow with the patient, and progressively growing vascular hamartomas which affect both venous and arterial limbs of the circulation and may threaten with limb loss or congestive heart failure. The afferent-efferent lesions require a multidisciplinary approach with close follow-up for their successful management.

Duplication of the hepatopancreatic bud presenting as pyloric stenosis.

Duplication of systemic organs is not a frequent finding. We report the occurrence of duplication of the hepatopancreatic bud with presence of mature hepatic and pancreatic tissue in a nine-day-old girl who presented with intestinal obstruction mimicking infantile hypertrophic pyloric stenosis.
