Use of esophagocrural sutures and minimal esophageal dissection reduces the incidence of postoperative transmigration of laparoscopic Nissen fundoplication wrap.

OBJECTIVES: Herniation of the fundoplication wrap through the esophageal hiatus is a common reason for surgical failure in children who have undergone laparoscopic Nissen fundoplication. Extensive mobilization of the gastroesophageal junction in combination with decreased adhesions after laparoscopy may contribute to the development of this complication. In an attempt to decrease the incidence of wrap migration, we changed our technique to minimal mobilization of the intraabdominal esophagus and to placement of esophageal-crural sutures. In this study, we investigate the impact of these modifications on outcome. METHODS: A retrospective analysis was performed on all patients undergoing laparoscopic fundoplication by the senior author (GWH) from January 2000 through December 2004. Those undergoing operation with extensive esophageal mobilization and without esophagocrural sutures (January 2000 to March 2002) (group I) were compared with those in whom there was minimal esophageal dissection with placement of these esophagocrural sutures (April 2002 to December 2004) (group II). RESULTS: Two hundred forty-nine patients underwent laparoscopic Nissen fundoplication during the study period. One hundred thirty patients were in group I, and 119 patients were in group II. The rate of transmigration decreased from 12% in group I to 5% in group II (P = .072). The relative risk of transmigration with extensive esophageal mobilization and without the esophagocrural sutures was 2.29. CONCLUSIONS: This retrospective study has shown that placement of esophagocrural sutures and minimization of the dissection around the esophagus results in a more than 2-fold reduction in the risk of wrap transmigration after laparoscopic Nissen fundoplication.

Relative value units correlate with pediatric surgeons' operating time: when perceived myth becomes reality.

PURPOSE: In 1992, the Congress implemented a Medicare payment system based on relative value units (RVUs). Today, RVUs are increasingly used to determine surgeon reimbursement from Medicare, Medicaid, and private third-party payers. We questioned whether current RVU assignments accurately reflect the quantity of time that surgeons spend operating. METHODS: Over a 12-month period, 59 common pediatric operations were identified and classified as general surgery (n = 34), urology (n = 13), or minimally invasive (n = 10). Only operations performed as an outpatient or requiring less than one inpatient day of direct surgeon involvement were included. By regression analysis, correlation coefficients were generated comparing average operating time per procedure to the corresponding RVU generated. RESULTS: Of 59 specific operations, a total of 744 general surgery cases, 1155 urological cases, and 370 minimally invasive cases were performed. RVU efficiency was greatest in general surgery (1 RVU = 5.18 operating minutes), followed by minimally invasive operations (1 RVU = 6.80 minutes) and urological operations (1 RVU = 8.59 minutes). Regression analysis proved minimally invasive operations to correlate best with RVUs with R2 = 0.8376, followed by urology at R2 = 0.6753, and then general surgery at R2 = 0.649. CONCLUSIONS: The RVU has emerged as the most dominant factor influencing reimbursement of practicing pediatric surgeons. Despite common surgeon bias, RVUs do correlate with current operating times. These data prove important as surgeons analyze cost, negotiate contracts, and strategically plan for fiscal success.

A simple and more cost-effective antibiotic regimen for perforated appendicitis.

OBJECTIVE: Appendicitis is the most common abdominal emergency in children. When perforation is encountered, postoperative management is grounded upon the use of intravenous antibiotics. The 3-drug regimen of ampicillin, gentamicin, and clindamycin has long been the accepted standard by pediatric surgeons. Although effective and seemingly inexpensive, this regimen produces a cumbersome dosing schedule, which has inspired the search for a simpler regimen that does not compromise efficacy or expense. To this end, we have introduced a 2-drug regimen of ceftriaxone and Flagyl (Pharmacia Corporation, Chicago, Ill) with once-a-day dosing. METHODS: A retrospective review was conducted of the most recent 250 patients treated at our institution with perforated appendicitis. Patients treated since the implementation of this 2-drug regimen were compared with the recent historical cohort treated with triple antibiotic coverage. Parameters analyzed between the 2 groups included temperature curves for the first 5 postoperative days, abscess rate, length of hospitalization, length of intravenous antibiotic treatment, and medication charges. RESULTS: The 2-drug regimen was used in 57 patients (group 1) compared with 193 patients treated with triple antibiotic coverage (group 2). Maximum recorded temperature between the 2 groups was similar upon admission, but the mean maximum temperature in group 1 became significantly lower than group 2 from postoperative day 1 onward (P < .001). Postoperatively, an abscess developed in 8.8% of group 1 compared with 14.2% of group 2, which was not significantly different (P = .37). Mean length of stay was 6.8 days in group 1 and 7.8 days in group 2 (P = .03). Medication charges to the patient were 81.32 dollars per day in group 1 compared with 318.53 dollars per day in group 2, translating to 1186.05 dollars savings for 5 days. CONCLUSIONS: Once-a-day dosing with ceftriaxone and Flagyl provides adequate antibiotic coverage for the postoperative management of perforated appendicitis in children. This regimen allows patients to more rapidly defervesce compared with traditional triple antibiotic coverage; moreover, this simple regimen provides substantial advantages for administration and expense.

Esophageal foreign bodies in the pediatric population: our first 500 cases.

BACKGROUND: Children with esophageal foreign bodies are frequently seen by pediatric surgeons. Choking and dysphagia are common presentations; however, esophageal perforation has been reported. Historically, rigid esophagoscopy with extraction of the foreign body has been the recommended treatment. Alternatively, Foley balloon extraction is a safe and effective approach. METHODS: Over a 16-year period, 555 children presented with an esophageal foreign body. Retrospective analysis of the medical record was undertaken. Statistics were by univariate analysis. RESULTS: Two hundred ninety-eight boys and 257 girls presented with a mean age of 3.24 years. Dysphagia (37%) and drooling (31%) were the most common symptoms. Foreign bodies were lodged in the superior esophagus in 73%, and 88% of the objects were coins. Balloon extraction with fluoroscopy was performed in 468 children. Eighty percent of the objects were successfully removed with a mean fluoroscopy time of 2.2 min, and 8% were advanced into the stomach. The overall success rate was 88%, with failures necessitating rigid esophagoscopy under general anesthesia. Children younger than 1 year were the most likely to fail (25% failure rate). Airway aspiration never occurred. Significant savings in patient charges were observed with this approach. CONCLUSIONS: Balloon extraction of pediatric esophageal foreign bodies is a safe and cost-effective procedure. This technique is applicable for infants, children, and adolescents. Experienced practitioners should be able to achieve greater than 80% success rate.

Gallbladder wall inflammatory cells in pediatric patients with biliary dyskinesia and cholelithiasis: a pilot study.

BACKGROUND/PURPOSE: Inflammation has been implicated in functional gastrointestinal disorders, including functional dyspepsia and irritable bowel syndrome. This study was undertaken to evaluate gallbladder wall inflammatory cells in children with abdominal pain related to gallstones and biliary dyskinesia to determine the candidate cell types that may be contributing to the pathophysiology of these entities. METHODS: Gallbladder specimens from 20 patients with cholelithiasis, 20 biliary patients with dyskinesia, and 12 autopsy controls were evaluated in a blinded fashion. Eosinophil, tryptase-positive, and CD3+ cell densities were determined for the lamina propria and muscularis mucosa layers and compared between groups. RESULTS: Patients with biliary dyskinesia and cholelithiasis had a 9- to 12-fold increase in mean and peak mast cell densities, respectively, in both layers as compared with controls. Peak (13.7 vs 8.4) and mean (9.2 vs 5.2) CD3+ cell densities were increased in the muscularis mucosae of cholelithiasis specimens as compared with biliary dyskinesia specimens. CONCLUSION: Gallbladder wall inflammatory cell densities, particularly mast cells, differ between children with cholelithiasis, children with biliary dyskinesia, and controls. Future studies are warranted to define the roles for specific inflammatory cell types.

Open versus laparoscopic pyloromyotomy for pyloric stenosis: a prospective, randomized trial.

BACKGROUND: Pyloric stenosis, the most common surgical condition of infants, is treated by longitudinal myotomy of the pylorus. Comparative studies to date between open and laparoscopic pyloromyotomy have been retrospective and report conflicting results. To scientifically compare the 2 techniques, we conducted the first large prospective, randomized trial between the 2 approaches. METHODS: After obtaining IRB approval, subjects with ultrasound-proven pyloric stenosis were randomized to either open or laparoscopic pyloromyotomy. Postoperative pain management, feeding schedule, and discharge criteria were identical for both groups. Operating time, postoperative emesis, analgesia requirements, time to full feeding, length of hospitalization after operation, and complications were compared. RESULTS: From April 2003 through March 2006, 200 patients were enrolled in the study. There were no significant differences in operating time, time to full feeding, or length of stay. There were significantly fewer number of emesis episodes and doses of analgesia given in the laparoscopic group. One mucosal perforation and one incisional hernia occurred in the open group. Late in the study, 1 patient in the laparoscopic group was converted to the open operation. A wound infection occurred in 4 of the open patients compared with 2 of the laparoscopic patients (P = 0.68). CONCLUSIONS: There is no difference in operating time or length of recovery between open and laparoscopic pyloromyotomy. However, the laparoscopic approach results in less postoperative pain and reduced postoperative emesis. In addition, there was a fewer number of complications in the laparoscopic group. Finally, patients approached laparoscopically will likely display superior cosmetic outcomes with long-term follow-up.

Hernia uterus inguinale: a proposed algorithm using the laparoscopic approach.

The authors present a case of hernia uteri inguinale, or the presence of Mullerian duct structures in an inguinal hernia. This entity presents in phenotypic males presumably secondary to defects in the action of the Mullerian inhibiting substance and presents a pediatric surgeon with management dilemmas. The long-term complications associated with the gonads if left intact include the risk of malignancy and infertility. We describe the use of the laparoscopic technique in the management of this condition and propose an algorithm for the management of this condition.

Cost considerations and applicant characteristics for the Pediatric Surgery Match.

BACKGROUND/PURPOSE: Formal training in pediatric surgery is highly competitive. The limited number of accredited positions has historically favored applicants with basic science experience, numerous publications, national presentations, and exposure to well-known pediatric surgeons. This review analyzes characteristics of successful applicants and cost associated with the Match. METHODS: A survey was e-mailed to 45 applicants after the 2003 Match. Geographic provenance, demographics, qualifications, costs, and valued program characteristics were assessed. Statistics were formulated by chi2 and Student's t test. RESULTS: Thirty-six applicants (80%) responded. Successful characteristics for matched vs unmatched included number of publications, 11.2 vs 5.7 (P < .01); first-author designation, 6.4 vs 3.1 (P = .02); basic science papers, 5.7 vs 1.7 (P < .01); national presentations, 5.8 vs 2.4 (P = .02); and presentations at pediatric surgical meetings, 2.0 vs 0.6 (P = .04). Ninety percent of matched applicants took time off to perform basic science research (P < .01). Average candidate expense was $6974, which represented 14% of pretax salary. Forty-one percent of applicants noted that cost limited the number of interviews taken. Fifty percent preferred a regional interview process to limit expense. Candidates ranked case diversity, volume, and mentor's advice as the most valued program characteristics. Successful applicants matched at their fifth rank on average. Eighty-six percent of unsuccessful applicants will reapply. CONCLUSIONS: Results of this study are important to those interested in the future of pediatric surgery. Successful applicants were shown to have several national presentations and multiple scientific publications, especially in basic sciences. Applicant costs are high, totaling more than $236,000 for survey respondents.

Management of postoperative infections after the minimally invasive pectus excavatum repair.

PURPOSE: Pectus excavatum is frequently repaired using the minimally invasive placement of a substernal bar (Nuss procedure). Infectious complications after the Nuss procedure are potentially devastating. To date, the management of postoperative infectious complications has not been well described. METHODS: A retrospective review of all patients (N = 168) who underwent the Nuss procedure from January 1, 1997, to October 1, 2003, at our institution was performed. Six patients (4%) had postoperative infections, and their medical records were reviewed. RESULTS: Of the 6 patients, 5 underwent operative drainage for wound abscesses that developed 2 to 76 weeks postoperatively. The other patient developed cellulitis 12 months postoperatively and was treated effectively with antibiotics alone. Recurrent infections were treated in 3 of 6 patients, one of whom eventually required removal of the bar resulting in a mild, residual pectus excavatum defect. One of 6 patients has had the substernal bar removed electively. The remaining 4 continue to be without clinically apparent infection at this time and are over 1 year removed from their infection. CONCLUSIONS: Although uncommon, infectious complications after the Nuss procedure require complex management strategies. Despite recurrent infection in some cases, most infectious complications occurring after the minimally invasive repair can be effectively treated without having to remove the substernal bar.

Laparoscopic patch repair of diaphragmatic hernias with Surgisis.

BACKGROUND: Laparoscopic repair of congenital diaphragmatic hernias has been sparsely reported. Moreover, each report has primarily been a single operative case. In most of the reports, prosthetic mesh has not been used, and when used, it has been nonabsorbable in nature. Most of these case reports have documented only a few months of clinical follow-up. METHODS: After institutional review board approval (No. 01-12-115X), the clinical course and outcome of 3 patients undergoing laparoscopic repair of foramen of Morgagni and Bochdalek hernias using 4-ply Surgisis soft tissue graft (Cook Inc, Bloomington, Ind) were reviewed to determine if this approach is appropriate. RESULTS: In 2001, 2 patients, ages 9 months and 14 years, underwent laparoscopic foramen of Morgagni repair and one 5-day-old underwent laparoscopic foramen of Bochdalek repair using Surgisis soft tissue graft as a patch to close the diaphragmatic defects because there was too much tension with primary repair. In each case, the prosthesis was secured to the rim of the defect using interrupted silk sutures tied intracorporally. The mean operative time for repair of the Morgagni defects was 230 minutes with a postoperative discharge of 1 and 2 days. For the foramen of Bochdalek repair, the operative time was 204 minutes, and the patient was discharged at 3 weeks. No complications have occurred during or after any of the procedures, but the oldest patient underwent diagnostic laparoscopy 3 months postoperatively for a radiographic finding of suspected recurrence. At laparoscopy, the patch was intact, and no diaphragmatic hernia was noted. CONCLUSIONS: Laparoscopic repair of congenital diaphragmatic defects using prosthetic material is possible although the operative time required is around 3.5 hours. Because of the brief postoperative course, the laparoscopic approach appears justified in the nonneonatal patients. Whether this approach is appropriate for repair of neonatal Bochdalek hernias remains unclear.

Urachal anomalies in children: the vanishing relevance of the preoperative voiding cystourethrogram.

PURPOSE: Children with a wet, draining, or infected umbilicus are often referred to pediatric surgeons. Unfortunately, uniform guidelines regarding diagnostic imaging are lacking. Historically, the persistence of the urachus was attributed to intrauterine distal urinary obstruction. Today, many surgeons continue to advocate preoperative voiding cystourethrogram (VCUG). METHODS: Records of children with urachal abnormalities over the past 10 years were reviewed. Demographics, presentation, imaging, genitourinary anomalies, operations, length of stay, and complications were recorded. Statistical evaluation was by descriptive analysis. RESULTS: Fifty-six children were diagnosed with urachal anomalies. Age at operation was 2.5 years (1 day-13 years). Fifty percent of patients were less than 1 year. Ultrasound was used in 88% of cases. Voiding cystourethrogram (34%) and computed tomography (14%) were also used. Average hospitalization was 1.9 (0-13) days. Thirty-two percent underwent operations as outpatients. Seven percent developed wound infections. Eight children (14%) had genitourinary anomalies. However, no VCUG examination (n = 19) documented an obstructive process. CONCLUSIONS: The current study represents the largest reported series of symptomatic urachal anomalies in children. Disorders of the urachus are variable in presentation with the diagnosis reliably made by history and ultrasound alone. Further testing, including VCUG, is not warranted, adding additional cost, an invasive procedure, and inconvenience to the child.

Thoracoscopic repair of esophageal atresia and tracheoesophageal fistula: a multi-institutional analysis.

OBJECTIVES: For the past 60 years, successful repair of esophageal atresia (EA) and distal tracheoesophageal fistula (TEF) has been performed via a thoracotomy. However, a number of reports have described adverse musculoskeletal sequelae following thoracotomy in infants and young children. Until now, only a few scattered case reports have detailed an individual surgeon's success with thoracoscopic repair of EA/TEF. This multi-institutional review represents the largest experience describing the results with this approach. METHODS: A cohort of international pediatric surgeons from centers that perform advanced laparoscopic and thoracoscopic operations in infants and children retrospectively reviewed their data on primary thoracoscopic repair in 104 newborns with EA/TEF. Newborns with EA without a distal TEF or those with an isolated TEF without EA were excluded. RESULTS: In these 104 patients, the mean age at operation was 1.2 days (+/-1.1), the mean weight was 2.6 kg (+/-0.5), the mean operative time was 129.9 minutes (+/-55.5), the mean days of mechanical ventilation were 3.6 (+/-5.8), and the mean days of total hospitalization were 18.1 (+/-18.6). Twelve (11.5%) infants developed an early leak or stricture at the anastomosis and 33 (31.7%) required esophageal dilatation at least once. Five operations (4.8%) were converted to an open thoracotomy and one was staged due to a long gap between the 2 esophageal segments. Twenty-five newborns (24.0%) later required a laparoscopic fundoplication. A recurrent fistula between the esophagus and trachea developed in 2 infants (1.9%). A number of other operations were required in these patients, including imperforate anus repair in 10 patients (7 high, 3 low), aortopexy (7), laparoscopic duodenal atresia repair (4), and various major cardiac operations (5). Three patients died, one related to the EA/TEF on the 20th postoperative day. CONCLUSIONS: The thoracoscopic repair of EA/TEF represents a natural evolution in the operative correction of this complicated congenital anomaly and can be safely performed by experienced endoscopic surgeons. The results presented are comparable to previous reports of babies undergoing repair through a thoracotomy. Based on the associated musculoskeletal problems following thoracotomy, there will likely be long-term benefits for babies with this anomaly undergoing the thoracoscopic repair.

Thyroglossal duct infections and surgical outcomes.

PURPOSE: Thyroglossal duct cysts (TGDC) are the most common head and neck congenital anomalies in children and often present as infected neck masses. The authors reviewed their experience with TGDC to determine if preoperative infection was related to postoperative complications, including recurrence and postoperative infection. METHODS: The medical records of 99 patients undergoing excision of TGDC from January 1991 to July 2002 were reviewed. Factors thought to be associated with recurrence (age, history of infection, drainage, abscess, and operative procedure) were analyzed. RESULTS: Ninety-nine patients made up the study group. The mean age at operation was 5.0 years (range, 6 months to 16 years) with a male to female ratio of 1.6:1. TGDC recurred in 12.1% (12 of 99) of these patients. There was no gender difference for those with and without recurrence. The presence of an abscess or cellulitis preoperatively (22 of 99 patients) did not correlate with recurrence (NS). In addition, postoperative infection occurred in 13 of 99 patients and also was independent of preoperative infection. However, postoperative infection clearly was associated with an increased risk of TGDC recurrence. Seven of 87 patients without recurrence had a postoperative infection, whereas 6 of 12 of those who had a recurrence had a postoperative infection (P <.001). The mean follow-up was 3.7 years and was comparable for the 2 groups (recurrence v. resolution). Twelve patients successfully underwent a second procedure for recurrence. CONCLUSIONS: In this large series of TGDC, preoperative infection occurred in approximately 1 of 5 patients and was not predictive of recurrence. Although postoperative infection did not correlate with the presence of preoperative infection, it was clearly associated with a statistically significant incidence of recurrent disease.

The parental perspective regarding the contralateral inguinal region in a child with a known unilateral inguinal hernia.

PURPOSE: The management of the contralateral region in a child with a known inguinal hernia has been debated by surgeons for more than 50 years. However, the perspective of the child's parents has not been sought, and this study was designed to evaluate parental views on this topic. METHODS: After IRB approval, all patients less than 10 years of age with a unilateral inguinal hernia seen by the senior surgeon were studied prospectively from November 2001 through February 2003. A study sheet was given to the parents about the nature of an inguinal hernia, the incidence of 20% to 40% of a contralateral patent processus vaginalis (CPPV), and the possible surgical options (perform repair of the unilateral inguinal hernia only, repair the unilateral inguinal hernia with contralateral exploration and repair if indicated, or unilateral inguinal hernia repair with laparoscopy through the ipsilateral hernia sac and repair of a CPPV if discovered). The parents of the last 113 patients requesting contralateral inspection were asked their motives (convenience or anesthesia concerns) regarding their decision. RESULTS: One hundred sixty-seven patients comprise the study group. Twelve parents chose unilateral repair alone, 13 chose bilateral incisions with contralateral repair if a CPPV was found, and 142 chose unilateral hernia repair with laparoscopic contralateral inspection followed by repair if needed. Regarding their motives, 90 of the last 113 parents requesting contralateral inspection indicated that convenience was the primary motive. Surprisingly, only 21 exhibited concerns about their child undergoing a second anesthesia. CONCLUSIONS: When presented options regarding management of a unilateral inguinal hernia, parents preferred laparoscopic inspection and repair of the contralateral region, if needed, more for convenience than for concerns about a second procedure and anesthesia.

An effective pyloromyotomy length in infants undergoing laparoscopic pyloromyotomy.

BACKGROUND: Traditional management of pyloric stenosis has consisted of open pyloromyotomy during which the surgeon is able to palpate and determine whether the hypertrophied pylorus has been completely divided. During the last decade, laparoscopic pyloromyotomy has become an increasingly popular approach for this condition. The purpose of this study was to determine whether there is an effective pyloromyotomy length that will allow the surgeon to feel confident that a complete pyloromyotomy was performed with the laparoscopic approach. METHODS: All infants undergoing laparoscopic pyloromyotomy from October 1999 through October 2003 at a single institution were retrospectively studied. Clinical variables collected included the patient's age, gender, electrolyte status on admission, the elapsed time from admission to operation, ultrasonographic dimensions of the hypertrophied pylorus, operative time, the length of the pyloromyotomy performed, the time to initial and to full feedings, and the duration of the postoperative hospitalization. RESULTS: One hundred seventy-one patients comprised the study group. The age (mean +/- standard deviation) at the time of operation was 5.2 +/- 2.8 weeks. The mean preoperative ultrasonic measurements for both pyloric thickness and pyloric length were 4.3 +/- 0.7 mm and 19.5 +/- 2.8 mm, respectively. The average pyloromyotomy incision length for this entire group was 1.9 +/- 0.21 cm. The mean operative time was 23.5 +/- 8.3 minutes. There were no mucosal perforations, no conversions to an open procedure, and no evidence for an incomplete pyloromyotomy. CONCLUSIONS: Laparoscopic pyloromyotomy is a safe and effective technique for infants with pyloric stenosis. A pyloromyotomy incision length of approximately 2 cm appears to be an effective measure of a complete pyloromyotomy.

The use of stab incisions for instrument access in laparoscopic urological procedures.

PURPOSE: Traditional laparoscopic procedures use expensive cannulas to facilitate the insertion and removal of laparoscopic instruments. We report our experience with limited access stab incisions for the insertion of instruments into the peritoneal cavity during laparoscopic urological procedures to minimize the use of disposable cannulas. MATERIALS AND METHODS: All patients undergoing laparoscopic urologic procedures using stab incisions, as performed by us, from November 1999 through March 2003 were included. Procedures included nephrectomy, partial nephrectomy, varicocelectomy, nephroureterectomy, orchiopexy and adrenal procedures. A single cannula was used for telescope access. In select cases additional cannulas were used for unique instruments or specimen manipulation/extraction. Abdominal wall stab incisions were used for the remaining instruments. Stab incisions were closed with a Steri-Strip (3M Healthcare, St. Paul, Minnesota) at the skin level only. RESULTS: A total of 53 procedures were performed during the study period. Pneumoperitoneum was maintained in all cases. There were no complications associated with the use of stab incisions. A total of 105 cannulas were saved using our technique. At a cost to the patient of dollars 140 per cannula the overall cost saving was dollars 14,700 with an average saving of dollars 277 per case. CONCLUSIONS: Laparoscopic urological procedures can be performed effectively and safely with stab incisions for instrument access. There are significant cost savings related to the elimination of cannulas. We believe that our technique of stab incisions for instrument access is equivalent to the traditional cannula approach and should be used when possible.

The use of stab incisions for instrument access in laparoscopic operations.

BACKGROUND/PURPOSE: Traditional laparoscopic approaches require cannulas for instrument access to the abdominal cavity. This study reports the authors' experience using minimal access (MA) stab incisions, rather than cannulas, for insertion of laparoscopic instruments into the peritoneal cavity. METHODS: All patients undergoing MA procedures by the authors from November 1999 through March 2003 were included. Procedures included foregut, biliary, adrenal, splenic, colonic, and genitourinary operations. A single cannula was used for insertion of the telescope. In select cases, a second cannula was needed for unique instruments (staplers/ultrasonic shears). Abdominal wall stab incisions (SI) were used for introduction of the remaining instruments. RESULTS: A total of 511 MA procedures were performed during the study period. Pneumoperitoneum was maintained in all cases. There were no complications associated with creation of the SI. A single-Step reposable (partially reusable, partially disposable) cannula and expandable sheath were used in 308 cases, whereas a second-Step reposable cannula and sheath were needed in 203 children. In total, 1,337 cannulas were saved using this MA technique. The cost to the patient was 140 dollars/Step cannula and sheath; overall cost savings were 187,180 dollars. CONCLUSIONS: MA procedures can be performed safely and effectively with a single or, occasionally, 2 cannulas. The cosmetic result is superior, and there are significant cost savings related to the elimination of accessory cannulas. The authors believe this technique of SI for instrument access is superior to the traditional cannula approach and can be utilized in most laparoscopic operations.
