Association of Intercostal Nerve Cryoablation During Nuss Procedure With Complications and Costs.

BACKGROUND: Intercostal nerve cryoablation with the Nuss procedure has been shown to decrease opioid requirements and hospital length of stay; however, few studies have evaluated the impact on complications and hospital costs. METHODS: A retrospective cohort study was performed for all Nuss procedures at our institution from 2016 through 2020. Outcomes were compared across 4 pain modalities: cryoablation with standardized pain regimen (n = 98), patient-controlled analgesia (PCA; n = 96), epidural (n = 36), and PCA with peripheral nerve block (PNB; n = 35). Outcomes collected included length of stay, opioid use, variable direct costs, and postoperative complications. Univariate and multivariate hierarchical regression analysis was used to compare outcomes between the pain modalities. RESULTS: Cryoablation was associated with increased total hospital cost compared with PCA (cryoablation, $11 145; PCA, $8975; P < .01), but not when compared with epidural ($9678) or PCA with PNB ($10 303). The primary driver for increased costs was operating room supplies (PCA, $2741; epidural, $2767; PCA with PNB, $3157; and cryoablation, $5938; P < .01). With multivariate analysis, cryoablation was associated with decreased length of stay (-1.94; 95% CI, -2.30 to -1.57), opioid use during hospitalization (-3.54; 95% CI, -4.81 to -2.28), and urinary retention (0.13; 95% CI, 0.05-0.35). CONCLUSIONS: Cryoablation significantly reduces opioid requirements and length of stay relative to alternative modalities, but it was associated with an increase in total hospital costs relative to PCA, but not epidural or PCA with PNB. Cryoablation was not associated with allodynia or slipped bars requiring reoperation.

Variations in Nuss Procedure Operative Techniques and Complications: A Retrospective Review.

INTRODUCTION: The Nuss procedure is the most common and preferred operative correction of pectus excavatum. Surgeon preference and patient factors can result in variations in Nuss procedure technique. We hypothesize that certain techniques are associated with increased risk of complications. MATERIALS AND METHODS: We performed a single-center retrospective review of Nuss operations from 2016 to 2020. Variations in intraoperative techniques included sternal elevator (SE) use, number of bars placed, and usage of bilateral stabilizing sutures. Patient demographics, intraoperative data, and postoperative outcomes were reported as median with interquartile ranges or percentages. Statistical significance (p < 0.05) was determined with Wilcoxon's rank-sum and chi-square tests. Multivariate analysis was performed to control for introduction of intercostal nerve cryoablation and surgeon volume, and reported as odds ratio with 95% confidence interval. RESULTS: Two hundred and sixty-five patients were identified. Patients repaired with two bars were older with a larger Haller index (HI). Patient demographics were not significantly different for SE or stabilizing suture use. Placement of two bars was associated with significantly increased risk of readmission. Similarly, SE use was associated with increased risk of pleural effusion and readmission. Finally, the use of bilateral stabilizing sutures resulted in less frequent slipped bars without statistical significance. CONCLUSION: Older patients with a larger HI were more likely to need two bars placed to repair pectus excavatum. Placement of multiple bars and SE use are associated with significantly higher odds of certain complications.

Mycobacterium simiae cervical lymphadenitis.

Mycobacterium simiae, a multidrug-resistant, opportunistic acid-fast bacillus, usually causes infection in immunocompromised hosts. We describe a previously healthy child with M. simiae necrotizing granulomatous cervical lymphadenitis. Cure was achieved with excision of the affected nodes and adjunctive antimicrobial therapy.

Outcomes after peritoneal dialysis catheter placement.

BACKGROUND: The purpose of this study was to review surgical outcomes after elective placement of peritoneal dialysis (PD) catheters in children with end-stage renal disease. METHODS: Children with PD catheters placed between February 2002 and July 2014 were retrospectively reviewed. Outcomes were catheter life, late (>30days post-op) complications (catheter malfunction, catheter malposition, infection), and re-operation rates. Comparison groups included laparoscopic versus open placement, age<2, and weight<10kg. Univariate and multivariate analysis were performed. RESULTS: One hundred sixteen patients had 173 catheters placed (122 open, 51 laparoscopic) with an average patient age of 9.7±6.3years. Mean catheter life was similar in the laparoscopic and open groups (581±539days versus 574±487days, p=0.938). The late complication rate was higher for open procedures (57% versus 37%, p=0.013). Children age<2 or weight<10kg had higher re-operation rates (64% versus 42%, p=0.014 and 73% versus 40%, p=0.001, respectively). Adjusted for age and weight, open technique remained a risk factor for late complications (OR 2.44, 95% CI 1.20-4.95) but not re-operation. DISCUSSION: Laparoscopic placement appears to reduce the rate of late complications in children who require PD dialysis catheters. Children <2years age or <10kg remain at risk for complications regardless of technique.

Traumatic hepatic artery laceration managed by transarterial embolization in a pediatric patient.

While blunt abdominal trauma with associated liver injury is a common finding in pediatric trauma patients, hepatic artery transection with subsequent treatment by transarterial embolization has rarely been reported. We present a case of a child who suffered from a hepatic artery injury which was successfully managed by supraselective transarterial microcoil embolization, discuss management strategies in these patients, and provide a review of currently available literature.

Video-assisted thorascopic repair of a subarachnoid-pleural fistula in a child after thoracic tumor resection: technical note.

STUDY DESIGN: Technical report. OBJECTIVE: To describe a minimally invasive surgical approach for the obliteration of a subarachnoid-pleural fistula in a 4-year-old child after resection of an intrathoracic ganglioneuroma. SUMMARY OF BACKGROUND DATA: Development of a subarachnoid-pleural fistula has been reported after thoracotomy for lung, chest wall, and spinal tumors, when an iatrogenic meningeal laceration results in establishing communication between the spinal subarachnoid space and the pleural cavity. METHODS: Review of a single case in which video-assisted thorascopic surgery (VATS) was used to deposit fibrin glue and to suture a pleural allograft. Literature review was performed to document other options to treat subarachnoid-pleural cerebrospinal fluid (CSF) fistula. RESULTS: At 10 months after VATS repair, the CSF fistula has remained closed. CONCLUSION: VATS technique should be considered for a safe, efficacious, and durable CSF leak repair and as an alternative to open thoracotomy in the pediatric age group.

Surgery for peptic ulcer disease in children in the post-histamine2-blocker era.

BACKGROUND/PURPOSE: The aim of this study was to determine the presentation, treatment, and outcome of children requiring surgery for peptic ulcer disease (PUD) in the post-histamine 2 -blocker era. METHODS: The charts of all children undergoing surgery for PUD in our institution since 1980 were retrospectively reviewed. Data were collected regarding clinical presentation, operative details, postoperative course, and outcome. RESULTS: Twenty-nine children (7.2 +/- 7.5 years) required surgery for complications of PUD. Indications for operation were bleeding (n = 11), pneumoperitoneum (n = 13), peritonitis (n = 3), and gastric outlet obstruction refractory to medical therapy (n = 2). For those children with bleeding, 8 had simple oversew of the bleeding ulcer(s), 2 had oversew with vagotomy and pyloroplasty, and 1 required vagotomy and antrectomy. All patients with perforation (n = 16) were treated with simple closure with or without omental patch. One child with gastric outlet obstruction underwent vagotomy and antrectomy and 1 had vagotomy and pyloroplasty. Preoperative risk factors or comorbidities were present in 27 of 29 patients and included steroid or nonsteroidal antiinflammatory drug medications in 13 children (only 3 of whom were receiving antiulcer prophylaxis). Postoperative complications occurred in 11 of 29 patients. Three (10%) children required reoperation for persistent or recurrent ulcer disease and 4 children died. CONCLUSIONS: PUD remains a highly morbid and mortal condition in children despite the availability of effective acid-reducing medications. Effective prophylaxis of children receiving steroids and nonsteroidal antiinflammatory drugs may play a role in decreasing the risk of PUD.

Sonographic diagnosis of multiple small-bowel intussusceptions in Peutz-Jeghers syndrome: a case report.

Peutz-Jeghers syndrome (PJS) is a rare, though well-described, hereditary polyposis syndrome associated with mucocutaneous pigmentation that typically presents in the second decade of life with complications related to intestinal polyps. We present two cases of teenaged girls presenting with small-bowel intussusceptions within a 3-month period. Sonographic examinations readily revealed small-bowel intussusceptions with secondary small-bowel obstruction. In both the symptoms were less severe than one would expect given the underlying pathology found at subsequent surgery. Sonographic imaging with pathologic correlation is provided.
