The identification and treatment of intestinal malrotation in older children.

PURPOSE: Intestinal malrotation is often diagnosed in infancy. The true incidence of malrotation outside of this age is unknown. These patients can present atypically or be asymptomatic and diagnosed incidentally. We evaluate the incidence, clinical presentation, ideal imaging, and intra-operative findings of patients with malrotation over 1 year of age. METHODS: Retrospective review was conducted in patients older than 1 year, treated for malrotation at a single pediatric tertiary care center from 2000 to 2015. Data analyzed included demographics, presentation, imaging, intraoperative findings, and follow-up. Patients predisposed to malrotation were excluded. RESULTS: 246 patients were diagnosed with malrotation, of which 77 patients were older than 1 year of age. The most common presenting symptoms were vomiting (68%) and abdominal pain (57%). The most common method of diagnosis was UGI (61%). In 88%, the UGI revealed malrotation. 73 of 75 were confirmed to have malrotation at surgery. Intra-operatively, 60% were found to have a malrotated intestinal orientation and 33% with a non-rotated orientation. Obstruction was present in 22% with 12% having volvulus. Of those with follow-up, 58% reported alleviation of symptoms. CONCLUSION: Despite age malrotation should be on the differential given a variable clinical presentation. UGI should be conducted to allow for prompt diagnosis and surgical intervention.

Delaying Appendectomy Does Not Lead to Higher Rates of Surgical Site Infections: A Multi-institutional Analysis of Children With Appendicitis.

OBJECTIVES: To investigate the association between time to appendectomy and the risk of surgical site infections (SSIs) in children with appendicitis across multiple NSQIP-Pediatrics institutions. BACKGROUND: Several recently published single institution retrospective studies have reported conflicting relationships between delaying appendectomy and the risk of increasing surgical site infections (SSI) in both children and adults. This study combines data from NSQIP-Pediatrics with institutional data to perform a multi-institutional analysis to examine the effects of delaying appendectomy on surgical site infections. METHODS: Data from NSQIP-Pediatrics between January 2010 and June 2012 for cases of appendectomy for appendicitis at 6 institutions (preoperative characteristics, time of operation, and postoperative occurrences) were combined with data from medical record review (length of symptoms; times of initial presentation, emergency department (ED) triage, and admission; and diagnosis as simple appendicitis (SA, acute) or complicated appendicitis (CA, gangrenous/ruptured)). Cochran-Armitage tests for trend and multivariable logistic regression models were used to evaluate associations between time to appendectomy and SSI. RESULTS: Of the 1338 patients included, 70% had SA and 30% had CA. Postoperative SSIs were more common in CA (5.7% vs 1.2%, P < 0.001). SSI rates did not differ significantly across hospitals (P = 0.17). Compared with patients who did not develop an SSI, patients who developed an SSI had similar times between ED triage and appendectomy (median (interquartile range) 11.5 hours (6.4-14.7) versus 9.7 hours (5.8-15.6, P = 0.36), and similar times from admission to appendectomy (5.5 hours (1.9-10.2) versus 4.3 hours (1.4-9.9), P = 0.36). Independent risk factors for SSI were CA (Odds Ratio (95% CI): 3.46 (1.48-8.10), P = 0.004), longer symptom duration (OR for a 10-hour increase: 1.05 (1.01-1.10), P = 0.02), and presence of sepsis/septic shock (2.70 (1.17-6.28), P = 0.02). CONCLUSIONS: A 16-hour delay from ED presentation or a 12-hour delay from hospital admission to appendectomy was not associated with an increased risk for SSI.

Understanding parental refusal of permission for child participation in surgical prospective trials.

PURPOSE: The success of prospective randomized trials relies on voluntary participation, which has been perceived as a barrier for successful trials in children who rely on parental permission. We sought to identify the reasons parents decline child participation to understand potential limitations in the consent process. METHODS: A prospective observational study was conducted in 92 patients asked to participate in prospective randomized trials between 2012 and 2015. Parental reasons for refusal were documented. RESULTS: The 92 refusals were distributed between studies investigating the management of circumcision, gastroschisis, pectus excavatum, appendicitis, pyloric stenosis, undescended testicles, abdominal abscess and gastroesophageal reflux. Reasons for refusal included preference of treatment path (37 %), inability to follow up (21 %), unspecified resistance to participate in research (18 %), preference to maintain independent surgeon decision (16 %), and desire for historically standard treatment (8 %). Of the families who opted to pursue a specific treatment arm rather than randomization, 35 % had prior experience with that treatment, 32 % had researched the procedure, 18 % wished to pursue the minimal intervention and 15 % did not specify. CONCLUSIONS: Parental preference of therapy is the most common reason for refusal of study participation. This variable could be influenced with more effective explanation of study rationale and existing equipoise.

Radiation exposure from head computed tomography scans in pediatric trauma.

BACKGROUND: We have previously reported that children receive significantly less radiation exposure after abdominal and/or pelvis computed tomography (CT) scanning for acute appendicitis when performed at our children's hospital (CH) rather than at outside hospitals (OH). In this study, we compare the amount of radiation children receive from head CTs for trauma done at OH versus those at our CH. METHODS: A retrospective chart review was performed on all children transferred to our hospital after receiving a head CT for trauma at an OH between July 2012 and December 2012. These children were then blindly case matched based on date, age, and gender to children at our CH. RESULTS: There were 50 children who underwent head CT scans for trauma at 28 OH. There were 21 females and 29 males in each group. Average age was 7.01 ± 0.5 y at the OH and 7.14 ± 6.07 at our CH (P = 0.92). Average weight was 30.81 ± 4.69 kg at the OH and 32.69 ± 27.21 kg at our CH (P = 0.81). Radiation measures included dose length product (671.21 ± 22.6 mGycm at OH versus 786.28 ± 246.3 mGycm at CH, P = 0.11) and CT dose index (53.4 ± 2.26 mGy at OH versus 49.2 ± 12.94 mGy at CH, P = 0.56). CONCLUSIONS: There is no significant difference between radiation exposure secondary to head CTs for traumatic injuries performed at OH and those at a dedicated CH.

Ceftriaxone-induced pseudolithiasis in children treated for perforated appendicitis.

PURPOSE: Ceftriaxone has been associated with development of pseudolithiasis. In our institution, it is used for treatment of perforated appendicitis in children. This study evaluated the occurrence of ceftriaxone-related pseudolithiasis in this population. METHODS: After obtaining IRB approval, we performed a retrospective chart review over 51 months. We included patients undergoing laparoscopic appendectomy for perforated appendicitis. All patients were treated with ceftriaxone post-operatively. Patients without initial or post-treatment gallbladder imaging available for review were excluded. RESULTS: There were 71 patients who met inclusion criteria with a mean (±SD) age of 10.8 ± 3.8 years. Of these, 14 % (n = 10) developed stones or sludge in the gallbladder. The mean duration of ceftriaxone therapy was 8.7 ± 3.8 days. The average time to post-antibiotic imaging was 11.5 ± 10.3 days from initiation of antibiotics. There was no significant difference in duration of ceftriaxone therapy in the children that developed pseudolithiasis or sludge (10.0 ± 4.9 days) compared to those that did not (8.5 ± 3.6, p = 0.26). One child (10 %) with pseudolithiasis went on to become symptomatic, requiring a laparoscopic cholecystectomy. CONCLUSIONS: In our experience, ceftriaxone use for perforated appendicitis is associated with a significant incidence of biliary pseudolithiasis, and is unrelated to duration of ceftriaxone therapy.

Need for subsequent fundoplication after gastrostomy based on patient characteristics.

BACKGROUND: Gastrostomy tube placement is common in children. Many of the conditions associated with need for gastrostomy are also associated with gastroesophageal reflux. It is not clear how many patients without complicated reflux will subsequently require a fundoplication or which conditions increase this risk. Therefore, we performed a two-center review to determine the disease-specific propensity for fundoplication after gastrostomy tube placement. METHODS: The data set was retrospectively collected from two centers from 2000 to 2008. All patients underwent gastrostomy tube placement without fundoplication owing to the surgeon's discernment that fundoplication was not needed at the time. Pearson's correlation was used to evaluate the influence of patient variables and operative approach against the subsequent need for fundoplication. Significance was defined as two-tailed P ≤ 0.01. Logistic regression analysis was used to evaluate independence. RESULTS: A total of 684 patients underwent gastrostomy tube placement only, of which 124 were open, 282 laparoscopic, and 278 endoscopic (percutaneous endoscopic gastrostomy). The mean patient age was 2.9 years. Subsequent fundoplication was performed in 62 patients (9.1%). The mean interval to fundoplication was 20.7 months. Cerebral palsy and anoxic brain injury had the most significant correlation with subsequent fundoplication. These were also independent predictors. The laparoscopic approach had a negative correlation with the subsequent need for fundoplication. CONCLUSIONS: The low incidence of subsequent fundoplication in children who undergo gastrostomy tube placement justifies conservative use of fundoplication in the absence of complicated reflux. Those with cerebral palsy and anoxic brain injury appeared to have the greatest risk of the need for subsequent fundoplication.

Predictive factors for successful balloon catheter extraction of esophageal foreign bodies.

INTRODUCTION: Foreign bodies in the esophagus are common in children. Time from ingestion to presentation is variable, and may not be known. Our center usually performs Foley catheter balloon extraction under fluoroscopy as the first step to attempt removal to prevent all patients from going to the operating room. The efficacy of this procedure has been reported. However, information is lacking about the relationship between presentation variables and the likelihood of success. METHODS: After IRB approval, we performed a retrospective single-center review from January 1988 to August 2011 of children with an esophageal foreign body. Pearson's correlation was used to evaluate the relationship between variables and successful balloon extraction for P < 0.05. A logistic regression was done to evaluate for independence. RESULTS: 819 patients presented with esophageal foreign bodies, with a mean age of 3.3 years. 572 patients underwent balloon extraction, 83 % successful. Mean ingestion duration was 16.6 h with fluoroscopy time of 2.3 min and mean number of attempts was 1.5. Successful balloon extraction had a negative correlation with refusal to eat, respiratory distress, cough, wheeze, upper respiratory infection symptoms, stridor, fever, duration of ingestion >1 day, unwitnessed ingestion, fluoroscopy time and number of balloon catheter attempts. There was a positive correlation between success and both age and duration of ingestion <1 day. Independent predictive factors were number of balloon catheter attempts. CONCLUSIONS: Patients with longer duration of ingestion, symptoms from the foreign body and increased number of removal attempts have a decreased likelihood of success with balloon catheter extraction and should not undergo prolonged efforts of removal.

Irrigation versus suction alone during laparoscopic appendectomy for perforated appendicitis: a prospective randomized trial.

BACKGROUND: The efficacy of irrigating the peritoneal cavity during appendectomy for perforated appendicitis has been debated extensively. To date, prospective comparative data are lacking. Therefore, we conducted a prospective, randomized trial comparing peritoneal irrigation to suction alone during laparoscopic appendectomy in children. METHODS: Children younger than 18 years with perforated appendicitis were randomized to peritoneal irrigation with a minimum of 500 mL normal saline, or suction only during laparoscopic appendectomy. Perforation was defined as a hole in the appendix or fecalith in the abdomen. The primary outcome variable was postoperative abscess. Using a power of 0.8 and alpha of 0.05, a sample size of 220 patients was calculated. A battery-powered laparoscopic suction/irrigator was used in all cases. Pre- and postoperative management was controlled. Data were analyzed on an intention-to-treat basis. RESULTS: A total of 220 patients were enrolled between December 2008 and July 2011. There were no differences in patient characteristics at presentation. There was no difference in abscess rate, which was 19.1% with suction only and 18.3% with irrigation (P = 1.0). Duration of hospitalization was 5.5 ± 3.0 with suction only and 5.4 ± 2.7 days with group (P = 0.93). Mean hospital charges was $48.1K in both groups (P = 0.97). Mean operative time was 38.7 ± 14.9 minutes with suction only and 42.8 ± 16.7 minutes with irrigation (P = 0.056). Irrigation was felt to be necessary in one case (0.9%) randomized to suction only. In the patients who developed an abscess, there was no difference in duration of hospitalization, days of intravenous antibiotics, duration of home health care, or abscess-related charges. CONCLUSIONS: There is no advantage to irrigation of the peritoneal cavity over suction alone during laparoscopic appendectomy for perforated appendicitis. The study was registered with clinicaltrials.gov at the inception of enrollment (NCT00981136).

Operative findings in antenatal abdominal masses of unknown etiology in females.

BACKGROUND: Perinatal findings of abdominal masses pose a diagnostic challenge to clinicians. This study presents the operative findings of patients who underwent exploration for perinatally identified abdominal masses of unknown etiology. METHODS: Retrospective review of all patients with abdominal masses of unknown etiology identified in the antenatal period was conducted from January 1, 2000 to July 1, 2010. Patient demographics were collected. Preoperative radiographic studies, operative findings, and pathologic evaluation were reviewed. RESULTS: There were 17 patients identified within the study period. The median age was 30 d at the time of operation (range 0-287 d). The median height was 51 cm (range 45-77 cm), and the median weight was 4.0 kg (range 2.6-10.4 kg). All patients were asymptomatic. After birth, ultrasound identified abdominal masses in 14 patients, and computed tomography scan was used in four patients where one patient had both an ultrasound and a computed tomography scan. Mass resection was performed using laparoscopy in 15 patients, whereas two patients underwent open resection. At the time of surgery, 11 patients were diagnosed with ovarian cysts, four patients with ovarian torsion with an associated cyst, and two patients with an enteric duplication cyst. On final pathology, eight patients had benign ovarian cysts, seven patients had hemorrhagic ovarian necrosis, and two patients had duplication cysts. CONCLUSION: Females with antenatally identified abdominal masses of unknown etiology appear to be benign in nature. In this series, a benign ovarian cyst is the most common diagnosis, and these lesions can be approached laparoscopically.

Interval appendectomy after perforated appendicitis: what are the operative risks and luminal patency rates?

BACKGROUND: The need for interval appendectomy after nonoperative management of a perforated appendicitis is being questioned owing to recent studies that estimated recurrence rates as low as 5% because of obliteration of the appendiceal lumen. We review our experience with interval appendectomy in this subset of patients to determine the postoperative outcomes and luminal patency rates. METHODS: A retrospective review was conducted of all children treated nonoperatively for a perforated appendicitis followed by elective interval appendectomy during the past 10 years. The data collected included initial hospitalization, convalescence period, perioperative course, and luminal patency rates. RESULTS: A total of 128 patients were identified, of whom 55% were male. Their mean ± SD age was 9.1 ± 4.2 years. The mean interval from the initial presentation to appendectomy was 65.9 ± 20.3 d. All but 2 of the patients underwent laparoscopic appendectomy with 3 conversions to open surgery. The mean operative time was 43.6 ± 19.2 min. The complication rate was 9%, including 1 postoperative abscess, 1 reoperation for bleeding, and 1 readmission for Clostridium difficile infection. Six patients had a superficial wound infection, and 2 patients underwent outpatient procedures for suture granuloma. No risk factors for complications were identified. Of the specimens, 16% had obliterated lumens. CONCLUSIONS: Major postoperative morbidity for interval appendectomy after a perforated appendicitis is low and should not be a deterrent in offering interval appendectomy to this subset of patients.

Single incision versus standard 3-port laparoscopic appendectomy: a prospective randomized trial.

BACKGROUND: Laparoscopic appendectomy through a single umbilical incision is an emerging approach supported by several case series. However, to date, prospective comparative data are lacking. Therefore, we conducted a prospective, randomized trial comparing single site umbilical laparoscopic appendectomy to 3-port laparoscopic appendectomy. METHODS: After Internal Review Board approval, patients were randomized to laparoscopic appendectomy via a single umbilical incision or standard 3-port access. The primary outcome variable was postoperative wound infection. Using a power of 0.9 and an alpha of 0.05, 180 patients were calculated for each arm. Patients with perforated appendicitis were excluded. The technique of ligation/division of the appendix and mesoappendix was left to the surgeon's discretion. There were 7 participating surgeons dictated by the call schedule. All patients received the same preoperative antibiotics and postoperative management was controlled. RESULTS: There were 360 patients were enrolled between August 2009 and November 2010. There were no differences in patient characteristics at presentation. There was no difference in wound infection rate, time to regular diet, length of hospitalization, or time to return to full activity. Operative time, doses of narcotics, surgical difficultly and hospital charges were greater with the single site approach. Also, the mean operative time was 5 minutes longer for the single site group. CONCLUSION: The single site umbilical laparoscopic approach to appendectomy produces longer operative times resulting in greater charges. However, these small differences are likely of marginal clinical relevance. The study was registered with clinicaltrials.gov at the inception of enrollment (NCT00981136).

The impact of postoperative abscess formation in perforated appendicitis.

BACKGROUND: Abscess after appendectomy for perforated appendicitis is the most common complication. We have completed three prospective trials and are conducting a fourth in which the included patients had either a hole in the appendix or a fecalith in the abdomen identified at the time of operation. The abscess rate in each of these trials was 20%. Multiple publications have focused on prevention and management of this postoperative complication but the total impact of an abscess on the hospital course has not been well documented. Therefore, we reviewed our experience with patients who developed a postoperative abscess to evaluate the total care received compared with those who recovered uneventfully. METHODS: Data from patients with abscess who have been enrolled in our prospective trials from April 2005 to December 2009 were utilized. Patients who recovered without complications in the most recent trial served as a comparison group, as this protocol offers the minimal length of stay without a predetermined length of stay. Data comparison included patient demographics, admission lab values, hospital length of stay, and hospital charges. RESULTS: There were 63 patients with a postoperative abscess and 61 patients without an abscess identified. Patients with an abscess were older (11.0 versus 9.7 y, P = 0.04) and had a higher mean body mass index (22.4 versus 19.5, P = 0.03). Total hospital length of stay was significantly longer in the abscess group (11.6 d versus 5.1 d, P ≤ 0.001). Total hospital charges doubled for patients who developed an abscess ($82,000 versus $40,000 P < 0.001). CONCLUSION: A postoperative abscess after appendectomy for perforated appendicitis translates into an average of an extra week in hospital care with double the total hospital cost.

The predictive value of Haller index in patients undergoing pectus bar repair for pectus excavatum.

BACKGROUND: The Haller index (HI) remains the standard metric to quantify the severity of pectus excavatum deformity. However, little data exist to determine how well this parameter correlates with the difficulty or early outcomes of repair. METHODS: The study population was comprised of all patients who underwent pectus bar repair for pectus excavatum on whom adequate preoperative images on computed tomography allowed for Haller index calculation, from December 1999 to February 2010. Patients with two bars placed for repair were excluded. All images were reviewed blinded to outcome and Haller index was calculated. Pearson's correlation was used to evaluate the relationship between age, length of operation, postoperative complications, and length of hospitalization. The correlations were performed on the entire population and then individual age groups analyzed: 5-11 y, 12-16 y, and over 17 y. Two-tailed P values were determined from the correlation coefficient and significance was defined as P ≤ 0.05. RESULTS: HI was available for 262 patients. There were 66 patients aged 5-11 y, 165 patients aged 12-16 years, and 30 patients over 17 y. The population was 80% male. In the entire population, there was a small correlation between postoperative pneumothorax and HI (R = 0.131, P = 0.05). There was no correlation between age, operative time, postoperative bar infection, or length of stay. No significant correlations existed in any of the individual age groups. CONCLUSION: The Haller index holds no correlation with age, operative time, postoperative bar infection, or length of stay.

The lack of efficacy for oral contrast in the diagnosis of appendicitis by computed tomography.

BACKGROUND: Oral contrast is often used with computed tomography (CT) for the diagnosis of appendicitis. This adjunct adds time to evaluation, not all patients can tolerate enteric bolus, and the diagnostic advantages have not been well defined. Therefore, we reviewed our experience to evaluate the impact of oral contrast on diagnostic efficiency and its impact on the patient. METHODS: After obtaining IRB approval, a retrospective review was conducted on patients who underwent CT with oral contrast for the indication of appendicitis over the last 4 years. Data recorded included demographics, CT results, emergency room course, operative findings, and pathology interpretation. All images were reviewed to identify presence/absence of contrast at or beyond the terminal ileum. RESULTS: There were 1561 patients, of whom, 652 (41.8%) were diagnosed with appendicitis and 909 (58.2%) were not (non-appendicitis). Contrast was identified at least to the level of the terminal ileum in 72.4% of the entire population. The contrast was present in 76.2% of the non-appendicitis patients and 67.0% of the appendicitis patients (P = 0.01). Mean time from oral contrast administration to CT imaging was 105.5 min, which was longer in patients with appendicitis (112.2 min) compared with non-appendicitis patients (100.9 min) (P = 0.01). Emesis of the contrast occurred in 19.3% of those with appendicitis and 12.9% of those without appendicitis (P = 0.001). Nasogastric tubes were placed in 5.8% of those with appendicitis and 5.1% of those without (P = 0.37). Appendicitis was confirmed at operation in 94.3% of those with contrast in the area and 94.4% of those without (P = 1.0). Pathology confirmed appendicitis in 90.6% of those with contrast in the area and 94.0% of those without (P = 0.17). CONCLUSION: Nearly 30% of patients receiving oral contrast for the CT diagnosis of appendicitis do not have contrast in the point of interest at the expense of emesis, nasogastric tube placement, and diagnostic delay. These detriments are amplified in patients who have appendicitis. Further, there appears to be no diagnostic compromise in those without contrast in the terminal ileum.

The role of laparoscopy in the management of malrotation.

BACKGROUND: Malrotation is currently treated via the Ladd's procedure. Many surgeons feel this operation should be performed using the open approach to facilitate adhesion development, thus decreasing the risk for volvulus. However, little comparative data exist on the relative merits of laparoscopy for this operation. Therefore, we have analyzed our experience with the open and laparoscopic Ladd's procedure. METHODS: A retrospective analysis of our most recent 13-y experience with the Ladd's procedure was performed. Demographics, approach, diagnosis, hospital course, and outcomes were measured. Data are expressed as mean +/- standard deviation. Comparative analysis was performed using a t-test. RESULTS: A total of 284 Ladd's procedures were performed during this time, of which 43 were approached laparoscopically. Conversion rate was 33%, usually due to concern for volvulus/orientation. Volvulus after Ladd's procedure occurred in six patients, all of whom underwent an open approach (2.4%). Recovery data excluding patients who underwent bowel resection are displayed in Table 1. CONCLUSIONS: A laparoscopic Ladd's procedure should be the initial approach in patients with malrotation in the absence of volvulus. We encourage a low threshold for conversion to an open approach if there is any concern about volvulus/orientation. This may decrease morbidity for patients who are found at operation to have a low risk of recurrent volvulus.

Laparoscopic management of intussusception in pediatric patients.

INTRODUCTION: Minimally invasive approaches are beginning to be employed in the management of pediatric patients with intussusception who fail radiographic reduction. Successful laparoscopic reduction has been demonstrated, but the utility of laparoscopy, for more complex cases, is less well documented. Therefore, we reviewed our experience with laparoscopy in patients with radiographically irreducible intussusception to document the safety and effectiveness of this approach. METHODS: We conducted a retrospective review of all of the patients who had a radiographically irreducible intussusception treated via the laparoscopic approach at a single institution from 1998 to 2008. Means are expressed +/- standard deviation. RESULTS: A total of 22 patients were identified, with an average age of 2.9 +/- 3.0 years. Average length of stay was 2.67 +/- 1.5 days (median, 2). Sixteen (73%) of the 22 patients were male. There were 19 ileocecal and 3 small bowel intussusceptions. Twenty patients (91%) were able to be managed entirely laparoscopically or via extension of the umbilical incision, while 2 necessitated conversion, using a right-lower quadrant incision. Nine patients had an extension of the umbilical incision; 7 of these underwent a bowel resection. Ten patients (46%) had a bowel resection, of which 5 were an ileocecectomy and 5 were segmental small bowel resection. There were a total of 9 patients with a pathologic lead point, 5 patients with lymphoid hyperplasia, and 4 with Meckel's diverticula. CONCLUSION: We conclude that laparoscopy is a reasonable approach to pediatric intussusception, even in the event when bowel resection is necessary.

Short-term natural history of the standard approaches for gastrostomy tube placement in the pediatric patient.

INTRODUCTION: Gastrostomy placement is a common procedure in the pediatric population. Standard approaches of tube placement include open, laparoscopic, and percutaneous endoscopic methods. Placement of the gastrostomy in relation to the fundus and the anterior abdominal wall is crucial to ensure adequate comfort and functionality. Misplacement may require repositioning of the gastrostomy, the rate of which has not been well documented. We, therefore, have reviewed a multi-institutional experience with gastrostomy tube placement to determine the short-term natural history of placement, based on approach, and to establish a cohort to determine the long-term natural history. METHODS: We conducted a retrospective review of all pediatric patients who underwent percutaneous endoscopic, laparoscopic, or open gastrostomy placement at two institutions from 2000 to 2008. RESULTS: There were a total of 1534 patients who underwent gastrostomy tube placement during this time period. The most common procedure was fundoplication with gastrostomy (N = 832), followed by gastrostomy alone (N = 420), and then percutaneous endoscopic gastrostomy (PEG) (N = 285). There were 4 (0.3%) gastrostomy tubes that required repositioning to a new site due to encroachment upon the rib margin. Two were open and 2 were PEG (P > 0.99). Twenty of 39 patients who had an open fundoplication following gastrostomy had the gastrostomy taken down during the procedure, compared to 5 of 31 patients (P = 0.03), who underwent laparoscopic fundoplication following gastrostomy. CONCLUSIONS: These data demonstrate that the need for gastrostomy tube repositioning is rare in the short term, regardless of approach, although a takedown of the gastrostomy is more likely when an open fundoplication is performed.

Current application of thoracoscopy in children.

BACKGROUND: The safety and efficacy of thoracoscopy for thoracic lesions and conditions in children is evolving. Our experience with thoracoscopy has expanded in recent years. Therefore, we reviewed our most recent 7-year experience to examine the current applications for thoracoscopy in children. METHODS: A retrospective review of all patients undergoing a thoracoscopic operation at Children's Mercy Hospital (Kansas City, MO) between January 1, 2000, and June 18, 2007, was performed. Data points reviewed included patient demographics, type of operation, final diagnosis, complications, and recovery. RESULTS: During the study period, 230 children underwent 231 thoracoscopic procedures. The mean age was 9.6 +/- 6.1 years with a mean weight of 36.6 +/- 24.1 kg. Fifty percent of the patients were male. The thoracoscopic approach was used for decortication and debridement for empyema in 79 patients, wedge resection for lung lesions in 37, exposure for correction of scoliosis in 26, excision or biopsy of an extrapulmonary mass in 26, operation for spontaneous pneumothorax in 25, lung biopsy for a diffuse parenchymal process in 15, lobectomy in 9, repair of esophageal atresia with a tracheoesophageal fistula (EA-TEF) in 8, clearance of the pleural space for hemothorax or effusion in 3, diagnosis for trauma in 1, and repair of bronchopleural fistula in 1. Conversion was required in 3 patients, all of whom were undergoing a lobectomy. Two of these were right upper lobectomies and the other was a left lower lobectomy with severe infection and inflammation. The mean time of chest tube drainage (excluding scoliosis and EA-TEF patients) was 2.9 +/- 2.0 days. There were no major intraoperative thoracoscopic complications. A correct diagnosis was rendered in all patients undergoing a biopsy. One patient required a second thoracoscopic biopsy to better define a mediastinal mass. Two patients developed postoperative atelectasis after scoliosis procedures. One patient had a small persistent pneumothorax after a bleb resection for a spontaneous pneumothorax. This subsequently resolved. CONCLUSIONS: In pediatric patients with thoracic pathology, thoracoscopy is highly effective for attaining the goal of the operation, with a low rate of conversion and complications.

The risk of developing a symptomatic inguinal hernia in children with an asymptomatic patent processus vaginalis.

BACKGROUND: Children with a symptomatic indirect inguinal hernia have a patent processus vaginalis (PPV). However, the reverse is unknown, as the natural history of PPV is unclear. Currently, there are little data regarding the incidence and time frame for developing a symptomatic hernia with a known asymptomatic PPV. METHODS: A retrospective chart review was conducted in children who were evaluated for a PPV during nonhernia laparoscopic surgery by a single pediatric surgeon (GWH) from 2000 to 2014. Those patients with intraoperative findings of PPV were followed up by chart review and phone inquiry. RESULTS: 1548 children underwent a laparoscopic operation, with 308 having an asymptomatic PPV. Phone contact was successful in 125 (43%) of these patients at a median of 8.1years (range 4.8-12.7) after the initial laparoscopic operation. Nineteen (13%) patients returned with a symptomatic hernia at a median age of 17months (range: 5-74) and a median presentation of 9months (range: 1-66) after the initial laparoscopy. Ten hernia repairs were unilateral and 9 bilateral. None of those who were contacted via phone inquiry reported hernia symptoms or hernia repair. CONCLUSIONS: These data suggest that the risk of developing a symptomatic hernia during childhood in the presence of a known PPV is relatively low. LEVEL OF EVIDENCE: Level 3; type of study: retrospective study.

Parental and Volunteer Perception of Pyloromyotomy Scars: Comparing Laparoscopic, Open, and Nonsurgical Volunteers.

INTRODUCTION: Despite evidence from prospective trials and meta-analyses supporting laparoscopic pyloromyotomy (LP) over open pyloromyotomy (OP), the open technique is still utilized by some surgeons on the premise that there is minimal clinical benefit to LP over OP. Although the potential cosmetic benefit of LP over OP is often cited in reports, it has never been objectively evaluated. METHODS: After internal review board approval, the parents of patients from a previous prospective trial who had undergone LP (n = 9) and OP (n = 10) were contacted. After consent was obtained, the parents and patients were asked to complete a validated scar scoring questionnaire that was compared between groups. Standardized photos were taken of study subjects and controls with no abdominal procedures. Blinded volunteers were recruited to view the photos, identify if scars were present, and complete questions if a scar(s) was seen. Volunteers were also asked about the degree of satisfaction if their child had similar scars on a four-point scale from happy to unacceptable. RESULTS: Mean age was 7 years in both groups. Parental scar assessment scores were superior in the LP group in every category. Blinded volunteers detected abdominal scars significantly more often in the OP group (98%) vs. the LP group (28%; P < .001). The volunteers detected a scar in 16% of the controls, comparable to the 28% detected in the LP group (P = .17). The degree of satisfaction estimate by volunteers was 1.78 for OP and 1.02 for LP and controls, generating a Cohen's d effect size of 5.1 standard deviation units comparing OP to either LP or controls (very large ≥1.3). CONCLUSIONS: Parents of children scored LP scars superior to OP scars. Surgical scars are almost always identifiable with OP while the surgical scars associated with LP approach invisibility to the observer, appearing similar to patients with no prior abdominal operation.
