Experience of Minimally Invasive Surgery in Neonates with Congenital Malformations in a Tertiary Care Pediatric Hospital.

Aim:The aim of this study is to report the experience with minimally invasive surgery (MIS) in neonates with congenital malformations in a tertiary care pediatric hospital.Materials and Methods:Design: descriptive study. All neonates undergoing MIS from 2013 to 2018 were included in the study. Perinatal data, characteristics of surgery, type and duration of analgesia, postoperative mechanical ventilation duration, postoperative hospitalization, and postoperative morbidity and mortality surgery-related rates were recorded.Results:Seventy-one neonates were included. Gestational age and weight at surgery ranged from 24 to 41 weeks and from 1350 g to 4830 g, respectively. Procedures performed were esophageal atresia/tracheoesophageal fistula repair, congenital diaphragmatic hernia repair, diaphragmatic plication, fundoplication/gastrostomy, intestinal atresia repair, and pancreatectomy. The median follow-up period was 14 months. Five neonates (7%) were converted to open, for surgical difficulties. Nine (12.6%) neonates had intraoperative complications, with decreased oxygen saturation as the most common complication. The median duration of analgesia and postoperative mechanical ventilation was 3 days in most procedures. The morbidity and mortality rates were 36.6% and 2.8%, respectively.Conclusions:In this first experience with MIS in neonates, the duration of analgesia and hospitalization was shorter for some procedures. However, intraoperative and postoperative complications were still high, which was possibly attributed to the learning curve. Thus, it is expected that the frequency of the complications presented in this study will be reduced in future.

Are Cardiac Anomalies and Persistent Fetal Circulation a Risk Factor for Cardiovascular Events During Minimally Invasive Surgery in Neonates?

Introduction: Minimally invasive surgery (MIS) in neonates is progressively performed. The aim of this study was to evaluate the risk for cardiovascular events during endoscopic surgery in neonates and to analyze the influence of persistent fetal circulation and/or cardiac anomalies. Materials and Methods: This is a retrospective single institution study including all neonates undergoing MIS. The charts were reviewed for intraoperative cardiovascular events and operative procedure was performed. Special attention was paid to cardiac anomalies and persistent fetal circulation. In addition, a review of the literature was performed. Results: Between January 2004 and December 2012, 108 neonates underwent MIS at our institution. Laparoscopic surgery was performed in 91 (84.3%) and thoracoscopy in 17 (15.7%) babies. None of these 108 patients developed a cardiovascular event during endoscopic surgery (0.0%). Persistent fetal circulation and/or cardiac anomalies were evaluated in 50 of 108 (46.3%) neonates. In the additionally performed review of the literature, four single case reports were identified. All 4 authors published a major cardiovascular event during laparoscopic surgery in neonates. In all 4 patients, gas embolism through a patent umbilical vein was assumed to be responsible for the cardiovascular event. Conclusions: In our opinion, the main risk factor for the development of a major cardiovascular event during MIS in neonates is vascular injury of a persistent umbilical vein. Persistent fetal circulation and/or cardiac anomalies seem to be less important. In case of injury of a persistent umbilical vein, the risk of gas embolism has to be respected and conversion to the open approach has to be considered.

Minimally invasive surgery in neonates

3-Dimensional (3D) laparoscopy improves operating time in small spaces without impact on hemodynamics and psychomental stress parameters of the surgeon.

Three-dimensional (3D) imaging, a recent technical innovation in laparoscopic surgery, has been postulated to enhance depth perception and facilitate operations. However, it has never been evaluated in conditions where the focus is close to the optical system. Thus, it is unclear whether 3D cameras can improve laparoscopic surgical performance in neonates and infants. We tested 3D versus two-dimensional (2D) vision during laparoscopic surgery in rabbits, mimicking the size of a neonatal patient. Cadaver New Zealand white rabbits (mean weight 2,755 g) were operated by two surgeons experienced in 2D laparoscopic surgery and two surgical residents (with basic skills in 2D laparoscopy). All surgeons had never performed 3D laparoscopic surgery. Animals underwent six operations: Nissen fundoplication, small bowel anastomosis, and closure of a diaphragmatic defect using either 2D or 3D. Primary endpoint was cumulative operating time and operating time of each operation. Secondary endpoints included the hemodynamic response and psychomental stress level of the surgeons. Finally, subjective data on depth perception were assessed by questionnaires. Cumulative operating time of all three types of operations was significantly shorter with 3D laparoscopy in experts (3D: 23.01 ± 5.65 min vs 2D: 29.51 ± 7.51 min, p < 0.01) and residents (3D: 27.95 ± 3.69 min vs 2D: 33.95 ± 6.21 min, p < 0.05). This effect could be shown for each operation in the expert group and the Nissen fundoplication in the resident group. There were no differences in the hemodynamic response as well as the psychomental stress level between 2D and 3D imaging. 3D provided better depth perception. 3D laparoscopy in small spaces is associated with a significant shorter operating time. It induces no additional physical or psychomental stress in surgeons naive to 3D imaging. 3D may therefore facilitate minimal invasive surgery in neonates and infants.

Minimally invasive surgery in neonates and infants

Minimally invasive surgery (MIS) has significantly improved the field of surgery, with benefits including shorter operating time, improved recovery time, minimizing stress and pain due to smaller incisions, and even improving mortality. MIS procedures, including their indications, impact, limitations, and possible future evolution in neonates and infants, are discussed in this article.

Feasibility of complex minimally invasive surgery in neonates

The aim of this study was to assess the feasibility of complex minimally invasive surgery in neonates (and infants <5 kg). A systematic search of databases was performed. Inguinal herniotomy and pyloromyotomy were specifically excluded. Various operations were assessed for operative times, conversion rates, complications and centres performing the procedures. From 479 abstracts, 50 papers were identified describing 1,215 patients. Common operations performed were fundoplication (n = 473), operations for ovarian pathology (n = 151) and oesophageal atresia repair (n = 123). Other not-so-common operations included Kasai procedure (n = 61), Ladd's procedure (n = 55), bowel atresia surgery (n = 45) and congenital diaphragmatic hernia repair (n = 41). Mean operation times varied from 43 min for fundoplication to 209 min for Kasai procedure, with other operation times falling in between the two extremes. Likewise, conversion rates varied from 0.2% for fundoplication to 15% for congenital diaphragmatic hernia, with other conversion rates falling in between. Complications ranged from 0 to 67%. About 70-94% of the cases were performed in six pioneering centres. Fundoplication and operations for ovarian pathology have low complication and conversion rates and appear to be well suited to the average-trained paediatric laparoscopic surgeon. More complex procedures are feasible and safe, but technically demanding and need further expertise.

Minimally Invasive Neonatal Surgery

Minimally invasive surgery is now an option to patients as light as 1.2 kg, extending the benefits of small incisions, faster recoveries, decreased pain, and more precise procedures in critically ill neonates. This article provides a review of the historical development of minimally invasive surgery and an overview of the equipment involved, identifies the roles of the neonatal and perioperative nurse, and briefly describes several minimally invasive surgery procedures currently performed in the neonatal population.

Minimally Invasive Surgery in Neonates: Ten Years' Experience

Background: This study reviews ten years' experience in our institution with minimally invasive surgery in infants. It evaluates the feasibility, safety, and efficacy of performing advanced endoscopic procedures in infants under 5 kg. Methods: From October 1992 through October 2002, 846 infants weighing 1.1 to 5.0 kg underwent 881 procedures using minimally invasive techniques. The majority of the procedures were performed using 3 mm instruments and 2.7 or 4 mm scopes. Procedures include Nissen fundoplication, pyloromyotomy, colon pull-through, patent ductus arteriosus (PDA) closure, Ladd's procedure, colon resection, congenital diaphragmatic hernia repair, tracheoesophageal fistula repair, and exploration. Results: Ninety-eight percent of procedures were completed successfully endoscopically. There were two intraoperative complications and no mortality. Days to discharge for patients admitted for their specific procedure were Nissen 1.1, PDA 1.3, pyloromyotomy 1, pull-through 2.6. Conclusions: This study...

Minimally invasive surgery in neonates

Minimally invasive surgery (MIS) has been one of the most important developments in surgery in the last century. By reducing the incision to small puncture wounds, morbidity, pain, adhesions and scarring are reduced. Due to their small size, neonates have not benefited from the advances in endoscopic surgery as rapidly as their adult counterparts. In the last 5 years, miniaturization of instruments and the development of sophisticated new techniques have enabled paediatric surgeons to apply endoscopic surgery to neonates. MIS is now being performed in both the neonatal chest and abdomen. This article reviews these new developments and discusses the potential for even further improvements in neonatal surgery in the future.

Thoracoscopic repair of tracheoesophageal fistula in newborns

Background: Advancements in minimally invasive surgery in neonates have allowed even the most complex neonatal procedures to be approached using these techniques. Methods: During a period of 15 months, 8 patients born with a proximal esophageal atresia and a distal tracheoesophageal fistula underwent repair thoracoscopically. Weights ranged from 2.1 to 3.4 kg and operating times ranged from 55 to 120 minutes. Results: All procedures were completed successfully thoracoscopically, and there were no operative complications. One patient had a small leak on day 4 that resolved spontaneously on day 8. All other patients were shown to have a patent anastomosis with no leak by Barium swallow on day 5. Conclusion: This initial report shows that esophageal repair in the neonate is technically feasible and may provide advantages in terms of exposure and esophageal length, as well as the recognized advantages of avoiding a thoracotomy.
