Background:  Surgical wound dehiscence (SWD) in neonates is a life-threatening complication. The aim was to define risk factors of postoperative incision dehiscence in this population.

Methods:  Data of 144 patients from 2010 to 2020 were analyzed retrospectively. All full-term newborns or preterm newborns up to 42 weeks of amenorrhea (adjusted) who had a laparotomy within 30 days were included. Descriptive patient information and perioperative data were collected. SWD was defined as any separation of cutaneous edges of postoperative wounds.

Results:  Overall, SWD occurred in 16/144 (11%) patients, with a significantly increased incidence in preterm newborns (13/59, 22%) compared with full-term newborns (3/85, 4%; p < 0.001). SWD was significantly associated with exposure to postnatal steroids (60% vs. 4%, p < 0.001) and nonsteroidal anti-inflammatory drugs (25% vs. 4%, p < 0.01), invasive ventilation duration before surgery (median at 10 vs. 0 days, p < 0.001), preoperative low hemoglobin concentration (115 vs. 147 g/L, p < 0.001) and platelet counts (127 vs. 295 G/L, p < 0.001), nonabsorbable suture material (43% vs. 8%, p < 0.001), the presence of ostomies (69% vs. 18%, p < 0.001), positive bacteriological wound cultures (50% vs. 6%, p < 0.001), and relaparotomy (25% vs. 3%, p < 0.01). Thirteen of 16 patients with SWD presented necrotizing enterocolitis/intestinal perforations (81%, p < 0.001).

Conclusion:  This study identified prematurity and a number of other factors linked to the child's general condition as risk factors for SWD. Some of these can help physicians recognize and respond to at-risk patients and provide better counseling for parents.

Objective:  Heterotopic pancreas (HP) is a condition in which there is well-differentiated pancreatic tissue that lacks any anatomic or vascular contact with the pancreatic gland. It normally arises from the stomach but can be found in other locations. Although it is usually asymptomatic, obstructive symptoms, bleeding, or malignant degeneration can occur. The incidence is very low, but it is significantly more common in patients with esophageal atresia (EA). The aim of this study is to evaluate the incidence of HP in patients with and without EA and to compare the results in both groups.

Material and methods:  We conducted a 2-year prospective study in pediatric patients who benefited from an upper gastrointestinal endoscopy. Patients were divided into two groups: group "A" comprised patients with EA and group "B" those without EA. The variables analyzed were the clinical presentation, presence of HP, location, associated malformations, genetic disorders, and management.

Results:  A total of 192 consecutive patients were included in the study: 51 (26.6%) in group A and 141 (73.4%) in group B. Indications for endoscopy in group B were eosinophilic esophagitis in 37 (19.2%) patients, celiac disease in 23 (11.95%) patients, and other disorders in 81 (42.2%) patients. Gastric HP was found in seven patients, all of them in group A. All lesions were hosted in the prepyloric antrum. The prevalence of HP in groups A and B was 13.7 and 0%, respectively (p < 0.05). Female gender was predominant in patients with AE and HP, this result being statistically significant (p = 0.044). No other associated malformation or genetic syndrome studied showed association with HP. Only one patient debuted with upper gastrointestinal (GI) bleeding and required excision, while six patients were asymptomatic. The mean follow-up was 54 months (range: 45-78 months).

Conclusion:  The incidence of gastric HP is more common in patients with EA, with the female gender being a risk factor for their association. Active search and follow-up is recommended as it may become symptomatic anytime and need resection.

Treatment of pilonidal sinus disease with conventional excision techniques is associated with recurrence up to 20 to 30% (primary closure) or with prolonged healing that might last months (closure by secondary intention). Endoscopic pilonidal sinus treatment (EPSiT) is gaining increasing popularity. This systematic review aims to summarize and evaluate the reported outcomes of pediatric EPSiT (PEPSiT) to date. Systematic search was performed for all studies on PEPSiT in patients younger than 18 years, pertaining to demographics, technique, and outcomes. Fisher's test was used to assess the associations between success/recurrence rates and different approaches (fistuloscope vs. cystoscope, different wound care protocols). A total of 320 patients (9 studies, 2018-2022) with a weighted mean age of 15.7 years and follow-up duration of 13.5 months were included. PEPSiT was successful in 290 patients (90.9%) with weighted mean time to healing of 4.1 weeks. Recurrence was reported in 29 patients (9.1%) with weighted mean time to recurrence of 4.6 months. Outcomes were not significantly altered by the use of fistuloscope versus pediatric cystoscope (p = 1.0), or with perioperative laser epilation (p = 0.06), or postoperative regular shaving, depilatory creams, light pulse, or laser (p = 0.31). The weighted mean operative time was 38 minutes and hospital stay was 16 hours. Summary of available evidence confirms that PEPSiT is safe and effective. Added to its noninvasiveness, PEPSiT's pooled outcomes appear superior to those of numerous conventional techniques. Comparison with conventional techniques, particularly off-midline flap and semi-closure procedures, is, however, lacking. The superiority of PEPSiT needs to be confirmed in future comparative studies, including cost-benefit analysis.

Introduction:  Conventional postoperative pain management, with an intravenous patient-controlled approach or thoracic epidural analgesia, has proved suboptimal following a minimally invasive repair of pectus excavatum. Considering its postulated mechanism of action, we encouraged cryoanalgesia as an effective method for postrepair pain management and a possibly superior alternative.

Methods:  A randomized, single-blind clinical trial was tested on patients undergoing pectus excavatum (PE) repair in March and December 2022. Among 101 patients, consenting study participants were randomly assigned to one of two groups: cryoanalgesia (group C, n = 24) or noncryoanalgesia (group N, n = 24). Group N received conventional pain management. Comparing the results, pain levels were measured using the visual analog scale (VAS-R for resting and VAS-D for dynamic) and the total rescue analgesic consumption was determined. Intrathoracic cryoablation was performed bilaterally on the fourth and seventh intercostal nerves using a cryoprobe at -80°C for 2 minutes.

Results:  The two groups had similar baseline-patient characteristics; however, group C had a longer mean operative time (159 vs. 125 minutes, p < 0.01) and experienced significantly less pain throughout the postoperative course, with VAS at 6 hours (5.38 vs. 7.04, p < 0.01) and 48 hours (3.17 vs. 5.67, p < 0.01).

Conclusion:  Cryoanalgesia improved postoperative pain control at rest and during movement following PE repair. However, the outcome was less favorable than expected because the VAS was greater than 4 (moderate pain), although after a day or two, it decreased to lower levels (VAS < 4) in the cyro group. Considering its extra invasiveness and instrumentation, a routine cryoanalgesia procedure for pectus surgery is yet to be determined.

Introduction:  Pigtail catheter (PGC) insertion due to spontaneous pneumothorax (SPT) in the pediatric population has increased markedly in the last years. However, only few studies examined its efficacy in terms of length of hospitalization, rate of complications, and especially pain management comparing to large bore catheter (LBC) insertion. We sought to compare analgetic drug consumption, efficacy, and complication rate between PGC and LBC in children with SPT.

Materials and methods:  This is a single-center retrospective study of pediatric patients that were admitted to the Schneider Children's Medical Center between 2013 and 2021 with a diagnosis of SPT. The following data were collected: type of drainage (PGC or LBC), duration of drainage, length of hospitalization, number of X-rays, complication rate, surgery during hospitalization, readmission due to SPT, and pain management.

Results:  Seventeen PGC and 23 LBC were inserted in our study. No differences were noted in terms of hospitalization length, tube reposition or replacement, and recurrence of SPT between the groups. Patients with PGC underwent less X-rays comparing to the LBC group (3 X-rays vs. 5, median, p < 0.005). Oral analgesic use in terms of length of therapy was significantly lower in the PGC group than in the LBC group (1 vs. 3+ days, median, p < 0.05). There was no major complication in this cohort.

Conclusion:  PGC is an effective, safe, and less painful alternative compared with a LBC for the drainage of SPT in children.

Introduction:  Posterior tracheopexy (PT) directly addresses the posterior trachealis membrane intrusion in severe tracheomalacia. During PT, the esophagus is mobilized and membranous trachea is sutured to the prevertebral fascia. Although dysphagia has been reported as a possible complication of PT, in the literature there are no data investigating postoperative esophageal anatomy and digestive symptoms. Our aim was to study clinical and radiological consequences of PT on esophagus.

Methods:  Patients with symptomatic tracheobronchomalacia scheduled for PT between May 2019 and November 2022 underwent pre- and postoperative esophagogram. For each patient, we analyzed radiological images and measured esophageal deviation providing new radiological parameters.

Results:  All 12 patients underwent thoracoscopic PT (n = 3) or robot-assisted thoracoscopic PT (n = 9). For all patients, the postoperative esophagogram showed a right dislocation of the thoracic esophagus (median postoperative deviation = 27.5 mm). We report an esophageal perforation at postoperative day 7 in a patient affected by esophageal atresia, who underwent several surgical procedures before. A stent was placed and esophagus healed. Another patient with severe right dislocation referred transient dysphagia to solids, which resolved gradually in the first postoperative year. All the other patients did not present any esophageal symptoms.

Conclusion:  For the first time, we demonstrate the right dislocation of the esophagus after PT and we propose an objective method to measure it. In most patients, PT is a procedure not affecting esophageal function, but dysphagia can occur if dislocation is important. Esophagus mobilization during PT should be cautious, especially in patients who underwent previous thoracic procedures.

Background:  Thoracoscopic repair of esophageal atresia (EA) with tracheoesophageal fistula (TEF) is becoming an increasingly widespread technique; there is still controversy about its indication in certain patients. Our objective is to analyze if potential risk factors such as major congenital heart disease (CHD) or low birth weight (LBW) are a limitation to this approach.

Methods:  Retrospective study (2017-2021) of patients with EA and distal TEF who underwent thoracoscopic repair were included. Patients with LBW less than 2,000 g or major CHD were compared with the rest.

Results:  Twenty-five patients underwent thoracoscopic surgery. Nine patients (36%) had major CHD. Five of them (20%) were LBW less than 2,000 g, and only 8% (2/25) presented both risk factors. There were no differences in terms of operative time, conversion rate, tolerance evaluated with gasometric parameters (pO₂, pCO₂, pH) or complications (anastomotic leak and stricture, both early or during follow-up) in patients with major CHD and LBW (1,473 ± 319 vs. 2,664 ± 402 g). One conversion to thoracotomy was performed in a neonate weighing 1,050 g due to anesthetic intolerance. There was no recurrence of TEF. One patient died at the age of 9 months, due to major uncorrectable heart disease.

Conclusion:  Thoracoscopic repair of EA/TEF is feasible technique in patients with CHD or LBW, with similar results to other patients. The complexity of this technique warrants individualizing the indication in each case.

Background:  Pectus excavatum deformities are usually repaired with a minimally invasive approach in which a metal bar is used to correct the chest wall abnormality. We aimed to evaluate long-term outcomes and patient satisfaction after surgical correction.

Methods:  Patients who underwent pectus excavatum repair and subsequent bar removal at a single tertiary care center from January 2000 to December 2020 were identified. A retrospective chart review was performed, and a telephone survey was conducted to evaluate perceived inward chest movement, need for surgeon reevaluation, surgical reintervention, and overall satisfaction. Data are presented as medians with interquartile ranges (IQRs) and frequencies with percentages.

Results:  A total of 583 patients were included. The survey response rate was 26.2% (n = 153). The respondents were predominantly male (80.4%, n = 123) with a median age at surgical correction of 14.9 years (IQR 12.9, 16.1) and a median Haller index (HI) of 3.8 (IQR 3.4, 4.5). Median time to bar removal was 2.9 years (IQR 2.5, 3.0) with a median age at removal of 17.7 years (IQR 15.5, 19.0). Median time from surgery to survey follow-up was 9.6 years (IRQ 5.0, 11.4) with respondents having a median age at follow-up of 25 years (IQR 22.0, 28.4). The satisfaction rate was 96.7% (n = 148) with a reintervention rate of 2.0% (n = 3). The perceived inward chest movement was 30.7% (n = 47) with 12.8% (n = 6) of those requesting surgical reevaluation.

Conclusion:  There is a high level of satisfaction many years after correction of pectus excavatum and bar removal. With the advent of cryoablative therapy since 2017, patient satisfaction improved by experience of less postoperative pain. Reintervention rate is low despite some patients reporting a perceived chest wall inward movement.
