Same-day discharge after a cholecystectomy is a common practice in the adult population and has been demonstrated as safe and viable for children as well. However, there is a lack of comprehensive teaching models for pediatric cholecystectomy. Drawing inspiration from standardized outpatient procedures, this study aimed to assess the clinical outcomes and feasibility of teaching programs and an Enhanced Recovery After Surgery (ERAS) protocol following ambulatory laparoscopic cholecystectomy in pediatric patients.In 2015, an ERAS pathway for laparoscopic cholecystectomy (LC) was implemented, focusing on admission procedures, surgery timing, anesthetic choices, analgesia, postoperative feeding, mobilization, and pain assessment. Day-case surgery was not applicable for acute cholecystitis, choledochal lithiasis, sickle cell disease, and hereditary spherocytosis cases. The protocol was employed for a group of attending surgeons and fellows, as well as a group of residents under the supervision of experienced surgeons. A retrospective analysis was conducted to evaluate the feasibility and effectiveness of ambulatory cholecystectomy in children and its utilization in training pediatric surgical trainees.Between 2015 and 2020, a total of 33 patients were included from a cohort of 162 children who underwent LC, with 15 children operated on by senior surgeons and 18 by young surgeons. The primary diagnoses were symptomatic gallbladder lithiasis (n = 32) and biliary dyskinesia (n = 1). The median age at the time of surgery was 11.3 years (interquartile range (IQR) 4.9-18), and the median duration of surgery was 54 min (IQR 13-145). One intraoperative complication occurred, involving gallbladder rupture and the dissemination of lithiasis into the peritoneal cavity. Three patients (9%) required an overnight stay, while no postoperative complications or readmissions within 30 days were observed. ERAS was successfully implemented in 30 patients (91%). No significant differences in surgical outcomes were noted between senior and young surgeons. At an average follow-up of 55 months, no long-term sequelae were identified.These findings align with the current trend of increasing use of outpatient laparoscopic cholecystectomy and underscore its feasibility in the pediatric population. The application of a structured ERAS protocol appears viable and practical for training the next generation of pediatric surgeons.Level III.
Background/Objective: Thoracoscopic repair of esophageal atresia (EA) is gaining popularity, but it is a highly technically demanding procedure. The aim of our study is to evaluate our outcomes in the management of type C EA comparing the thoracoscopic and the open (thoracotomy) approaches. Methods: This is a retrospective bicentric study of two major pediatric surgery centers, reviewing all the patients operated for EA with distal tracheoesophageal fistula. Only patients who underwent primary anastomosis were included. From 2008 to 2018, 187 patients were included. Results: Forty-seven patients were operated thoracoscopically (TS group) and 140 by the open approach (TT group). Mean gestational age was 38 ± 2.4 weeks in TS group and 36.4 ± 3.3 weeks in TT group (P = .005) with a mean birth weight of 2785 ± 654 g and 2404.9 ± 651 g in TS and TT groups, respectively (P = .003). The mean operative time was 127.6 ± 35 minutes in TS group and 105.7 ± 23 minutes in TT group (P = .0005). The mean postoperative ventilation time and the mean length of stay were significantly shorter in the thoracoscopic group (P = .004 and P < .0001, respectively). The incidence of anastomotic leak was 8.9% in TS group versus 16.4% in TT group (P = .33). Anastomotic stenosis occurred in 33.3% of TS group and in 22.4% of TT group (P = .17). Conclusions: Surgical outcome of thoracoscopic repair of EA is comparable to the open repair with no higher complication rate with the expected skeletal and cosmetic benefits. However, possible bias regarding prematurity, weight at surgery, and associated anomalies must be taken into consideration.
Congenital pulmonary airway malformation (CPAM) is the most common pulmonary malformation. It can be managed via thoracoscopic lobectomy, which is safe and advantageous over thoracotomy. Some authors advocate the need for early resection to get an advantage over lung growth. Our study aimed to evaluate and compare the pulmonary function in patients who underwent thoracoscopic lobectomy for CPAM before and after 5 months of age.This retrospective study was conducted between 2007 and 2014. Patients younger than 5 months were assigned to group 1 and those over 5 months of age were assigned to group 2. Pulmonary function tests (PFT) were requested for all the included patients. For patients who could not undergo full PFT, the function residual capacity (FRC) was evaluated by the helium dilution technique. The parameters evaluated in full PFT were forced expiratory volume in one second (FEV1), forced vital capacity (FVC), total lung capacity (TLC), and FEV1 to FVC ratio (FEV1/FVC). The Mann Whitney U test was used to compare both groups of patients.Seventy patients underwent thoracoscopic lobectomy during this period, 40 of which had CPAM. Twenty-seven patients tolerated and underwent PFT (group 1: 12 patients; group 2: 15 patients). Among them, 16 patients underwent full PFT and 11 patients had FRC measurement. FRC was similar in both groups (91% vs. 88.2%). FEV1 (83.9% vs. 86.4%), FVC (86.8% vs. 92.6%) and TLC (86.5% vs. 87.8%) were also similar between both groups. FEV1/FVC was slightly higher in group 1 (97.9% vs. 89.4%) but the difference was not statistically significant.PFT for patients who underwent thoracoscopic lobectomy for CPAM before or after 5 months of age is normal and comparable between both groups. Surgical resection of CPAM can be performed safely early in life without any consequences for pulmonary function or more complications when older children undergo surgery.
Introduction: The interest in laparoscopy in the treatment of ureteropelvic junction obstruction (UPJO) in children under 12 months of age remains controversial. The aim of this study is to evaluate feasibility and benefits of retroperitoneal laparoscopy (RL) compared to open surgery in this age group. Materials and Methods: Between January 2012 and May 2017, we performed 222 pyeloplasties: 144 by laparoscopy and 78 by open surgery. From 2012, the choice of operative technique was decided according to the laparoscopic experience of the surgeon; two surgeons operated laparoscopically on all children <12 months of age, while others operated using posterior lumbotomy (PL). The RL is standardized and performed by 3 trocars (5, 3, 3). Pre, per and postoperative parameters were analyzed retrospectively. Statistical tests: Pearson, Fisher, Student and Mann-Whitney. Results: During this 5-year period, 24 RL and 53 PL were included with a median follow-up of 27 months (5-63). In the LR group, postoperative drainage was performed by JJ (13 cases) and external stent (11 cases). No conversion has been listed in this group. In each group there was one failure that needed redo pyeloplasty. Duration of hospitalization and intravenous acetaminophen use were significantly lower in the RL group (2.8 vs. 2.3 days, p = 0.02, respectively) while operating time was significantly longer (163 vs. 85.8 min, p = 0.001). The postoperative complication rate was statistically identical in each group (urinary tract infection, wall hematoma, hematuria…). Conclusion: RL is feasible in children under 1 year of age in the hands of well-experienced surgeons with longer operative time but without added morbidity. Subject to the retrospective nature of our study, the RL seems to offer a benefit regarding duration of hospitalization and analgesics consumption.
Purpose. To determine the feasibility and effectiveness of redo laparoscopic pyeloplasty among patients with failed previous pyeloplasty, specifically examining rates of success and complications. Materials and Methods. We retrospectively reviewed the charts of all patients, who underwent redo laparoscopic pyeloplasty from 2006 to 2017. This included patients who underwent primary pyeloplasty at our institution and those referred for failures. Analysis included demographics, operative time, complications, length of hospital stay, complications, and success. Success was defined as improvement of symptoms and hydronephrosis and/or improvement in drainage demonstrated by diuretic renogram, especially in those with persistent hydronephrosis. Descriptive statistics are presented. Results. We identified 22 patients who underwent redo laparoscopic pyeloplasty. All had Anderson-Hynes technique except two cases in which ureterocalicostomy was performed. Median (IQR) follow-up was 29 (2-120) months, median time between primary pyeloplasty and redo laparoscopic pyeloplasty was 12 (7-49) months. The median operative time was 200 (50-250) minutes, and median length of hospital stay was 3 (2-10) days. The procedure was feasible in all cases without conversion. During follow-up, all but two patients demonstrated an improvement in the symptoms and the degree of hydronephrosis. 91% of patients experienced success and no major complications were noted. Conclusions. Redo laparoscopic pyeloplasty is feasible and effective with a high success rate and low complication rate.
Obstructive nephropathy constitutes a major cause of pediatric renal progressive disease. The mechanisms leading to disease progression are still poorly understood. Kidney fibrotic lesions are reproduced by a model of partial unilateral ureteral obstruction (pUUO) in newborn mice. Based on data showing significant mast cell (MC) infiltration in patients, we investigated the role of MC and murine MCPT4, a MC-released chymase, in pUUO using MC- (Wsh/sh), MCPT4-deficient (Mcpt4-/-) and wild-type (WT) mice. Measurement of kidney length and volume by magnetic resonance imaging (MRI) as well as post-mortem kidney weight revealed hypotrophy of operated right kidneys (RK) and compensatory hypertrophy of left kidneys (LK). Differences between kidneys were major for WT, minimal for Wsh/sh and intermediate for Mcpt4-/-mice. Fibrosis development was focal and increased only in WT-obstructed kidneys. No differences were noticed for local inflammatory responses, but serum CCL2 was significantly higher in WT versus Mcpt4-/- and Wsh/sh mice. Alpha-smooth muscle actin (αSMA) expression, a marker of epithelial myofibroblast transformation (EMT), was high in WT, minimal for Wsh/sh and intermediate for Mcpt4-/- RK. Supernatants of activated MC induced αSMA in co-culture experiments with proximal tubular epithelial cells. Our results support a role of MC in EMT and parenchyma lesions after pUUO involving, at least partly, MCPT4 chymase. They confirm the importance of morphologic impairment evaluation by MRI in pUUO.
