Background: Robotic-assisted surgery (RAS) holds many theoretical advantages, especially in pediatric surgical procedures. However, most robotic systems are dedicated to adult surgery and are less suitable for smaller children. The Senhance^® Surgical System (SSS^®), providing 3 mm and 5 mm instruments, focuses on making RAS technically feasible for smaller children. This prospective observational study aims to assess whether RAS in pediatric patients using the SSS^® is safe and feasible. Methods and Results: A total of 42 children (aged 0–17 years, weight ≥ 10 kg) underwent a RAS procedure on the abdominal area using the SSS^® between 2020 and 2023. The study group consisted of 20 male and 22 female individuals. The mean age was 10.7 years (range 0.8 to 17.8 years), with a mean body weight of 40.7 kg (range 10.1 to 117.3 kg). The 3-mm-sized instruments of the SSS^® were used in 12 of the 42 children who underwent RAS. The RAS procedures were successfully completed in 90% of cases. The conversion rate to conventional laparoscopy was low (10%), and there were no conversions to open surgery. One of the 42 cases (2%) experienced intraoperative complications, whereas six children (14%) suffered from a postoperative complication. Overall, 86% of the patients had an uncomplicated postoperative course. Conclusions: The results of the current observational study demonstrate the safety and feasibility of utilizing the SSS^® for abdominal pediatric RAS procedures. The study provides new fundamental information supporting the implementation of the SSS^® in clinical practice in pediatric surgery.

Background: The effect of pediatric inguinal hernia repair (IHR) on testicular vascularization remains unclear. Manipulating the spermatic cord during surgery may reduce blood flow due to edema and vasoconstriction. This can lead to testicular atrophy. The study aims to review current knowledge of testicular vascular impairment following IHR in children. Methods: A systematic literature search was conducted in PubMed/Medline, Embase, Cochrane Library, and Web of Science. Methodological quality was assessed using validated tools. Data were extracted, and a pooled data analysis was performed. Results: Ten studies were included in the systematic review. Six of these studies were eligible for meta-analysis. This revealed a significant decrease in testicular vascularization during the short-term follow-up (1 day–1 week) after IHR using the open surgical approach. This decrease was not present after laparoscopic intervention. There was no more increased resistance in the vessels at long-term follow-up (1 month–6 months), suggesting that the impaired vascularity is only temporary. Conclusions: There seems to be a short-term transient vascular impairment of the testis after open IHR in children. This might be of clinical relevance to prefer the laparoscopic approach for IHR in children, even though the open approach is the gold standard, in contrast to adult IHR. The impact on testicular function and sperm quality later in life remains unclear. Comparative studies of both techniques are needed to determine if there is a significant difference in testicular vascularity. Long-term studies are necessary to assess the impact of transiently reduced vascularity on sperm quality and fertility later in life.

Background: Nissen Fundoplication (NF) is a frequently performed procedure in children. Robotic-assisted Nissen Fundoplication (RNF), with the utilization of the Senhance^® Surgical System (SSS^®) (Asensus Surgical^® Inc., Durham, NC, USA) featuring 3 mm instruments, aims to improve precision and safety in pediatric surgery. This matched cohort study assesses the safety and feasibility of RNF in children using the SSS^®, comparing it with Laparoscopic Nissen Fundoplication (LNF). Methods and Results: Twenty children underwent RNF with the SSS^® between 2020 to 2023 and were 1:1 matched with twenty LNF cases retrospectively selected from 2014 to 2023. Both groups were similar regarding male/female ratio, age, and weight. Two of the twenty RNF cases (10%) experienced intraoperative complications, whereas three in the LNF group of whom two required reinterventions. The observed percentage of postoperative complications was 5% in the RNF group compared to 15% in the LNF group (p = 0.625). The operative times in the RNF group significantly dropped towards the second study period (p = 0.024). Conclusions: Utilizing SSS^® for NF procedures in children is safe and feasible. Observational results may tentatively suggest that growing experiences and continued development will lead to better outcomes based on more accurate and safe surgery for children.

Introduction: Inguinal hernia repair (IHR) is one of the most common procedures in pediatric surgery. In children, the application of robotic surgery is limited, meaning safety and efficacy is still to be assessed. This report is the first one worldwide that describes inguinal hernia repair in children using the Senhance^® Surgical System (SSS^®). The aim of this matched cohort study is to assess safety and feasibility of robot-assisted IHR (RIHR) in children, compared to conventional laparoscopic IHR (LIHR). Patients and methods: This pilot study included 26 consecutive patients between 3 months and 8 years old who underwent RIHR (31 IH’s) with the SSS^® between 2020 and 2024. These cases were matched based on gender, age, and unilateral or bilateral IH, with 26 patients (32 IH’s) who underwent conventional LIHR. Results: There was a significant difference in total anesthesia time, which is most likely due to the extra time needed to dock the robot in the RIHR cases. No significant difference was seen in surgical time. One recurrence (3.2%) was diagnosed in both groups. One patient in the LIHR group was readmitted on the day of discharge due to a hemorrhage. No intervention was necessary, and the patient was discharged 1 day later. Discussion: In this pilot study, the use of the robotic system was safe and feasible. More experience, further improvement of the system for use in very small children, and investigation in a larger sample size with long-term follow-up is necessary to evaluate efficacy.

Low rectal surgery remains challenging. New surgical stapler devices have been developed to counteract problems of impaired visibility and inability to get low into the pelvis. One of them is the Radial Reload (RR) with Tri-staple(™) Technology (Covidien, New Haven, CT, USA). The aim of this study was to assess the first impressions and experiences regarding handling of this new stapler device in low anterior resection procedures in living humans. A questionnaire, consisting of 27 statements concerning accessibility, maneuverability and visibility, was sent to 35 surgeons worldwide. A total of 85 rectal surgical procedures, both open and laparoscopic, were assessed by 31 surgeons. In 97% of the procedures the surgeons agreed that the RR stapler device facilitated access in the low pelvis. The first stapler device firing achieved complete transection in 54% of the procedures. According to the surgeons' assessments, in 91% percent of the procedures the RR stapler device enabled creation of adequate margins. Visualization of the pelvic floor was reported in 93% of the procedures. In the surgeons' opinion, the RR stapler device was considered clinically acceptable in 93% of the procedures. In 79% of the procedures the surgeon preferred the RR stapler device over the stapler device they normally used. This study showed that the first experiences with the RR stapler device of 33 surgeons in 85 low rectal procedures are positive. It facilitates low stapling in both open and laparoscopic procedures. Good visibility, maneuverability and the possibility to create adequate distal margins were reported.

Surgical esophageal atresia (EA) repair is a complex operation with high risk of perioperative complications. Infants born with very low or extreme low birth weight (VLBW or ELBW) might be even at higher risk for developing perioperative complications. However, studies about this specific patient group are scarce, resulting in a knowledge gap on the outcomes of these infants. This hampers identifying the optimal treatment strategy, but also good counselling of parents. The aim of this study was to evaluate the mortality and surgery-related complication rates of VLBW and ELBW infants with EA after surgical esophageal repair in a multi-center cohort. A multi-center retrospective cohort study was performed in five academic hospitals in the Netherlands. Data was extracted from the medical record of patients born with EA and birthweight 1000-1500 g (VLBW) or <1000 g (ELBW) between 2000 and 2019. The main outcomes were overall mortality and specific surgery-related morbidity 90 days postoperative. Only descriptive analyses were performed. In total, 44 children were born with EA and VLBW/ELBW, of which 39 were included who underwent EA repair, 10 ELBW and 29 VLBW. Of the 39 infants, 25 had additional congenital anomalies. Six out of 29 VLBW infants and three out of 10 ELBW infants deceased. Complications occurred in 17 VLBW and two ELBW infants. Anastomotic stricture was the most frequent complications (VLBW n = 12, ELBW n = 1), others were anastomotic leakage (VLBW n = 5, ELBW n = 0), pneumothorax (VLBW n = 5, ELBW n = 0), surgical site infection (VLBW n = 1, ELBW n = 1) and recurrent fistula (VLBW n = 0, ELBW n = 1). Mortality and surgery-related complication rates in VLBW/ELBW infants after surgical EA repair in this large cohort are in line with previous studies. However, outcomes after surgical repair of EA are worse compared to infants born with a normal birthweight. This information is important to consider during parent counseling and multidisciplinary consultation.
