Objective: The authors present their experience in the management of pediatric patients with Herlyn–Werner–Wunderlich syndrome (HWWS) considering clinical classification and anatomical characteristics of the malformation. Methods: All the data of the patient presented at our Pediatric Surgery Unit from February 2010 to August 2015 were collected. According to the type of malformations, patients were divided in 3 groups: A (completely obstructed hemivagina), B (incompletely obstructed hemivagina), and C (communication between the duplicated cervices). Results: Six patients were treated in the study period. The mean age was 9 years (2 months–15 years). According to the characteristics of the HWWS, we had 5 patients in group A, 1 in group B, and none in group C. One-stage surgical treatment was performed in all cases of complete obstruction, but in one case a second look was necessary for a better resection of the septum. At a mean follow-up of 18 months all patients were symptoms free. Conclusions: Prognosis of this malformation is good in case of early diagnosis and treatment. We suggest that when a renal agenesia is diagnosed, the patient needs an ultrasonographic follow-up of the contralateral kidney but also of the genital tract to find each minimal abnormalities, furthermore, a MRI scanning before the onset of menstruation can be necessary.

Fetal intestinal volvulus is a rare condition that can lead to hemorrhage, bowel necrosis, and urgent surgical treatment after birth. Thus, prompt diagnosis and treatment are essential to avoiding fetal or neonatal demise. Prenatal ultrasound is a keystone tool in the diagnostic course. However, sonographic findings tend to be non-specific, with limited understanding of the pathophysiology behind their atypical presentation. With a literature review and a case series, we aim to optimize the antenatal diagnosis and management of this rare but life-threatening condition. Six cases from our institution were retrospectively analyzed over 12 years. A literature review was conducted until December 2022. A total of 300 articles matched the keyword “Fetal volvulus”, and 52 studies were eligible for the review. Our 6 cases are added to the 107 cases reported in the literature of fetal intestinal volvulus with antenatal ultrasound assessment and without associated gastroschisis or omphalocele. Several prenatal symptoms and ultrasound markers, even if not specific, were more frequently reported. Different experiences of management were described regarding follow-up, the timing of delivery, the mode of delivery, and surgery outcomes. This paper highlights the importance of suspecting and assessing fetal volvulus at routine ultrasound scans, describing the most frequent antenatal presentations and management in order to improve fetal and neonatal outcomes.

Background: Robot-assisted pyeloplasty is widely used in pediatric surgery because of its well-known advantages over open or laparoscopic surgery. The aim is to explore our experience and evaluate the achievements we have made. Methods: We evaluated patients undergoing robotic pyeloplasty from January 2016 to November 2021, including those who presented with a ureteropelvic junction obstruction associated with other anomalies of the kidney. The parameters examined were: age, weight, associated renal malformations, conversion rate, operative time, and intra- and postoperative complications. Results: Of 39 patients, 7 (20%) were included, of whom 5 (71%) were male and 2 (29%) were female. The mean age at surgery was 84 months (range 36–180 months), and the mean weight at surgery was 24.4 kg (range 11–40 kg). In five (71%) patients the ureteropelvic junction obstruction (UPJO) was left-sided and in two (29%) it was right-sided. In four (57%) cases, UPJO was associated with a horseshoe kidney, right-sided in one (25%) patient, and left-sided in the other three (75%). A 180° rotation of the kidney was present in one (14%) patient. Nephrolithiasis was present in two (29%) patients. The mean operative time was 160 min (range 140–240 min). The average bladder catheter dwell time was 1 day (range 2–3 days), while the average abdominal drainage dwell time was 2 days (range 2–4 days). The mean hospitalization time was 4 days (range 3–9 days). On average, after 45 days (range 30–65) the JJ ureteral stent was removed cystoscopically. No intraoperative complications were reported, while one case of persistent macrohematuria with anemia requiring blood transfusion occurred postoperatively. Conclusions: Ureteropelvic junction obstruction might be associated with other congenital urinary tract anomalies such as a duplicated collecting system, horseshoe kidney, or pelvic kidney. These kinds of malformations can complicate surgery and require more attention and accuracy from the surgeon. Our experience shows that, with regards to the robotic learning curve required for pyeloplasty, the treatment of the ureteropelvic junction in these situations does not present insurmountable difficulties nor is burdened by complications. The application of robot-assisted surgery in pediatric urology makes difficult pyeloplasties easier.

Introduction: Robotic surgery has shown explicit benefits and advantages in adults, but it is not yet strongly established in the pediatric population, even though its popularity is increasing, especially in the urologic field. Materials and methods: In this article we present our experience with the Da Vinci System (SI first and XI nowadays) at our pediatric institution in order to analyze our progress over the years. We considered all patients from the start of the robotic surgery program in 2016 until the end of 2021, dividing them into general abdominal surgery and genitourinary surgery. Analyzed data were the patient’s demographic, details of surgery, and intra and post-operative complications. Results: The total number of patients (pts) included in this study was 76, of whom 40 (52%) were male and 36 (48%) were female. The mean age at surgery was 90.9 months (range 10–207 months), and the mean weight at surgery was 29.3 kg (range 9.5–68 kg). There were 18 general abdominal robotic surgeries and 58 genitourinary robotic surgeries performed. The most performed surgeries in these two categories were fundoplication for gastro-oesophageal reflux disease (11%) and Anderson–Hynes pyeloureteroplasty. The mean operative time was 224.2 min (range 72–530 min): the mean times in the two groups (general abdominal surgery and genitourinary surgery) were 165 min (range 84–204 min) and 194 min (range 95–360 min), respectively. A total of four (5%) minor complications were reported. The total conversions were two (2.6%) and the mortality rate was 0%. Conclusions: Pediatric robotic surgery is a field of considerable interest and it is rapidly expanding. In our experience, it is evident how the learning curve has increased gradually, but steadily, allowing us to advance from standardized surgery, such as fundoplication and pieloplasty, towards a more technically complex one, achieving the same good results. We believe that robotic surgery is very respectful of tissues and feasible, especially for reconstructive surgery. For these reasons, it could become of common use also in the pediatric population, overcoming impediments such as excessive cost and the lack of pediatric instruments, in order to be able to treat children with a progressively lower age and weight.

Laparoscopic Appendectomy (LPSA) is the first choice for appendectomy in pediatric surgery. Trans-Umbilical Laparoscopic Assisted Appendicectomy (TULAA) is another used technique. We compared both these procedures used for the treatment of acute appendicitis. The study was conducted between January 2019 to December 2020. Patients were divided into two groups: LPSA and TULAA groups. The collected data were: operative time, number of conversions, time of canalization and hospital stay. A total of 181 patients were included: 73 were kept in the LPSA and 108 in the TULAA group. Mean operative time was 70.9 minutes (range 45-130 min) for LPS and 56.4 (30-145 min) for TULAA group (p <0.0001). Complications rate showed no statistically significant difference between both the two groups. However, conversions showed a statistically significant difference (p=0.04). Both techniques showed similar results. TULAA technique takes a significantly shorter operating time. The selection between LPSA and TULAA techniques depends on the experience of the surgeon’s work and the personal laparoscopic learning curve. In our experience LPSA was a useful technique to improve the laparoscopic skill of the pediatric surgery residents.
