Assessment of quality of life after laparoscopic GERD surgery in children: a prospective study.

The purpose of this study is to assess quality of life (QoL) after laparoscopic anti-reflux surgery (LARS) in children with gastroesophageal reflux disease (GERD) and to evaluate GERD symptoms and their impact on daily life and school. From June 2016 to June 2019, all children with GERD from 2 to 16 years of age, without neurologic impairment or malformation-related reflux, were prospectively included in a monocentric study. Patients (or their parents according to the age of the child) answered the Pediatric Questionnaire on Gastroesophageal Symptoms and QoL (PGSQ) before surgery and 3 and 12 months after surgery. Variables were compared by paired, bilateral Student t-test. Twenty-eight children (16 boys) were included. The median age at surgery was 77 months (IQR: 59.2-137) with median weight of 22 kg (IQR: 19.8-42.3). All had a laparoscopic Toupet fundoplication. Median duration of follow-up was 14.7 months (IQR: 12.3-22.5). One patient (4%) had a recurrence of GERD symptoms without abnormalities on follow-up examinations. Preoperative total PGSQ score was 1.42 (± 0.7) and decreased significantly 3 months (0.56 ± 0.6; p < 0.001) and 12 months after surgery (0.34 ± 0.4; p < 0.001). PGSQ subscale analysis revealed a significant decrease at 3 and 12 months for GERD symptoms (p < 0.001), impact on daily life (p < 0.001), and impact on school (p = 0.03). CONCLUSION: There was a significant improvement in symptoms and their frequency after LARS in children, as well as an improvement of QoL, in the short and medium term. The impact of GERD should be taken into consideration in the treatment decision, given that surgery clearly improves the QoL. WHAT IS KNOWN: • Laparoscopic anti-reflux surgery (LARS) is an established and effective treatment option in pediatric patients with severe GERD refractory to medical treatment. • Effect of LARS on the quality of life (QoL) has been mainly investigated in the adult population but there is very little data on the effect of LARS on the QoL in pediatric patients. WHAT IS NEW: • Our prospective study was the first to analyze the effect of LARS on QoL in pediatric patients without neurologic impairment using validated questionnaires at two postoperative time points with a significant improvement in postoperative QoL at 3 and 12 months. • Our study emphasizes the importance of evaluating QoL and impact of GERD on all the aspects of daily life and of taking these into consideration in the treatment decision.

Symptomatic Parapelvic Cysts in Children: Anatomical and Histological Features, Diagnostic Pitfalls and Urological Management.

BACKGROUND: Symptomatic parapelvic cysts (PPC) are rare entities. Our objective is to highlight specific features of PPC to avoid a misdiagnosis of UPJ obstruction. METHODS: We retrospectively reviewed the records of children managed between 2012-2017. RESULTS: All four patients (18 months-8 years) presented with acute renal colic with a large intra-sinusal liquid mass (42-85 mm) on ultrasound, evoking a diagnosis of UPJ obstruction. On preoperative renal scintigraphy (n = 3) there was no dilatation of the renal pelvis and ipsilateral differential function was impaired in 2. Diagnosis of PPC was suspected preoperatively in three children (CT scan (n = 1); MRI (n = 2)) and made peri-operatively (n = 1). Preoperative retrograde pyelography (n = 3) and a further intraoperative retrograde pyelography with methylene blue (n = 1) did not identify communication with the cyst. No renal pelvis was identified in two patients. De-roofing of the cyst was curative in all cases at 5 years mean follow-up (no leakage, cyst recurrence or loss of function) and all 4 patients became asymptomatic after surgery. Histology demonstrated a single flat epithelial cell layer. Renal function normalized in one patient but remained impaired in the other. CONCLUSION: In case of symptoms of UPJ obstruction with a medial renal liquid mass on ultrasound, PPC should be considered when no dilatated pelvis on renal scan is identified. In such cases, a complementary imaging work-up is mandatory prior to surgery.

Peritoneovenous Shunt for Intractable Ascites in Children: A Series of 4 Cases.

ABSTRACT: Intractable ascites is a rare condition in children mainly caused by cirrhosis or lymphatic disorders. Internal drainage may be considered as rescue therapy. In our department, 4 patients ages from 2 months to 15 years old underwent a peritoneovenous shunt (PVS) placement between 2010 and 2020. The surgically inserted device was a pumping device that enabled to drain ascites from the peritoneum into the venous system via the internal jugular vein (Denver shunt, BD Company, NJ). Immediate efficient drainage was achieved in all cases and lasted up to 9 years. Two major complications occurred: a postoperative fat embolism requiring urgent temporary ligation of the shunt and endocarditis shortly after inguinal hernia repair performed 16 months after placement of the shunt. Implementation of a PVS may be a useful procedure in patients with refractory ascites. Chylous ascites should be drained and washed totally before activating the device to avoid fat embolism. Antibiotic prophylaxis is required when abdominal surgery is planned while the device is in place.

Comprehensive Review of 3D Segmentation Software Tools for MRI Usable for Pelvic Surgery Planning.

Patient-specific 3D modeling is the first step towards image-guided surgery, the actual revolution in surgical care. Pediatric and adolescent patients with rare tumors and malformations should highly benefit from these latest technological innovations, allowing personalized tailored surgery. This study focused on the pelvic region, located at the crossroads of the urinary, digestive, and genital channels with important vascular and nervous structures. The aim of this study was to evaluate the performances of different software tools to obtain patient-specific 3D models, through segmentation of magnetic resonance images (MRI), the reference for pediatric pelvis examination. Twelve software tools freely available on the Internet and two commercial software tools were evaluated using T2-w MRI and diffusion-weighted MRI images. The software tools were rated according to eight criteria, evaluated by three different users: automatization degree, segmentation time, usability, 3D visualization, presence of image registration tools, tractography tools, supported OS, and potential extension (i.e., plugins). A ranking of software tools for 3D modeling of MRI medical images, according to the set of predefined criteria, was given. This ranking allowed us to elaborate guidelines for the choice of software tools for pelvic surgical planning in pediatric patients. The best-ranked software tools were Myrian Studio, ITK-SNAP, and 3D Slicer, the latter being especially appropriate if nerve fibers should be included in the 3D patient model. To conclude, this study proposed a comprehensive review of software tools for 3D modeling of the pelvis according to a set of eight criteria and delivered specific conclusions for pediatric and adolescent patients that can be directly applied to clinical practice.

Safety of laparoscopic fundoplication in children under 5 kg: a comparative study.

BACKGROUND: Laparoscopic fundoplication in children under 5 kg is still debated. Our objective was to evaluate the safety and efficacy of laparoscopic fundoplication (LF) in children under 5 kg. METHODS: We reviewed the cases of 96 children treated by laparoscopic fundoplication between 2005 and 2014. Thirty-five patients had a weight of 5 kg or less at the time of LF (Low Weight Group) and 61 patients had a weight between 5.1 and 10 kg (High Weight Group). The pre-operative, peri-operative, post-operative data regarding surgery and anesthesia were compared between groups. RESULTS: Mean weight was 3.9 ± 0.8 kg in the LWG and 7.8 ± 1.5 kg in the HWG. Children in the LWG were more prone to pre-operative respiratory management (40% mechanical ventilation and 42.9% oxygen therapy). The operating times (82 ± 28 min for LWG and 85 ± 31 min for HWG) and respiratory parameters during the procedure (PCO2) were comparable between groups. Post-operative complications were 1 gastric perforation with peritonitis and 1 small bowel obstruction in the LWG, 2 cases of gastric perforation with peritonitis in the HWG. Mean follow-up was 67 ± 44 months. Significant recurrence of GERD requiring a redo fundoplication was noted in 3 patients in the LWG and 1 patient in the HWG. CONCLUSION: Laparoscopic fundoplication is a safe procedure in infants ≤ 5 kg without increase of post-operative complications, recurrence, or mean operative time.

Low-Cost Training Simulator for Open Dismembered Pyeloplasty: Development and Face Validation.

PURPOSE: Surgical simulation has benefited from a surge in interest over the last decade because of the increasing need for a change in the traditional apprenticeship model of teaching surgery. Open surgery for ureteropelvic junction (UPJ) poses unique training challenges owing to smaller workspaces, and finer sutures used that require increased surgical dexterity when compared with adult analogues. We describe the development and face validation of a low-cost training simulator for open dismembered pyeloplasty. MATERIALS AND METHODS: The simulator is built with A4 Kraft envelopes, catheter tip syringe filled with 30mL of air, tape, 260 modeling balloon, and 11-in party balloon. Evaluation of the device is based on an evaluation form including 11 items on a 5-point Likert-type scale. Thirty-one departments of pediatric surgery in France were contacted and received a pack containing 4 to 10 devices, already set up and ready for use, a tutorial and an evaluation form. Candidates were stratified according to their level of expertise. RESULTS: A total of 180 devices were sent. Procedures on the device were performed 118 times (65%) by expert surgeons (n = 44), fellows (n = 25), and residents (n = 49). Statistically significant difference was noted for 4 items (anatomy, model exposition, UPJ resection, and difficulty) for the 3 levels of expertise. The global score evaluation for realistic items, face validity, and usability was 4.2 (range: 1-5). CONCLUSION: This low-cost model is evaluated as an efficient tool for UPJ teaching and training. It shows promise as an educational tool.

The Fisher Technique for Correction of Penile Torsion in Children: Who Are the Candidates?

OBJECTIVE: To report our experience in the treatment of penile torsion with a special reference to the Fisher technique. PATIENTS AND METHODS: We reviewed 30 cases of congenital penile torsion treated from 2009 to 2015 in a single center. Sixteen patients presented a moderate rotation of 45°-90° and 14 had a severe rotation with an angle greater than 90°. Chordee was present in 17 cases and distal glanular hypospadias in 15 cases. Median age at surgery was 10 months. In 14 cases, degloving along with skin realignment, alone, allowed correction of the torsion. In 16 cases, the Dartos flap (Fisher technique) was used. RESULTS: Out of the 30 patients, 29 had a good result, with a complete correction of the torsion. Only 1 patient had a residual torsion of 30°. Complications were minor and consisted of skin excess in 11 patients; 1 single case needed to be reoperated for that skin complication. The need for the Dartos flap procedure was significantly correlated to the degree of torsion (P = .001): it was used in 4 out of 16 patients (25%) with a torsion of less than 90°, and in 12 out of 14 patients (86%) with a torsion of 90° or more. CONCLUSION: Most of penile rotations less than 90° can be corrected by skin degloving and realignment. The Fisher technique is a simple and safe procedure for correction of persistent rotation after skin degloving; such cases have usually a penile rotation greater than 90°.

Adrenocortical tumor with precocious puberty in a 2-month-old girl.

Adrenocortical tumor is a rare childhood tumor with a median age at onset of 3.2 years. Virilization is the most common sign. Laparotomy is the reference treatment and has a favorable course. The diagnosis of adrenal tumor can be difficult. The main parameters of malignant tumors are size and metastasis. Analysis of TP53 mutation can facilitate final diagnosis. We report a case of virilizing adrenal tumor that developed in a 2-month-old girl, and which was treated with laparoscopic adrenalectomy.
