RESUMO
AIM: This survey analyzed techniques in laparoscopic inguinal hernia repair (LIHR) across pediatric age groups. MATERIALS AND METHODS: Data were collected through an online survey for pediatric surgeons, comprising of 38 questions, conducted by the European Pediatric Surgeons' Association (EUPSA) Trainees of European Pediatric Surgery (TEPS) LIHR Working Group. RESULTS: The survey was completed by 183 surgeons from 22 countries. Seventy-seven percent of respondents had performed LIHR at least once. Regarding preferences about the patient's gender, 7% respondents perform LIHR only in selected females, 9% routinely in females, 15% in both genders with age/weight restrictions, 24% routinely in both genders, 31% in selected cases, and 14% never perform LIHR. Percutaneous internal ring suturing (PIRS) was the preferred technique in all age groups, with totally extraperitoneal and transabdominal preperitoneal repairs preferred by 9% in adolescents. The majority (59%) repaired a contralateral patent processus vaginalis if present. Hydro-dissection (21%) and additional intra-abdominal instruments (42%) were preferred more often for male patients. The distal hernia sac was left intact by most respondents (92%). Responses regarding recurrence rates varied: 40% responded that LIHR had recurrence rates comparable to open surgery, whereas 10% reported increased recurrences and hence limited its use, and 10% consider that slightly increased recurrences are outweighed by lower complication rates associated with laparoscopic methods and thus continue LIHR. CONCLUSIONS: PIRS is the preferred choice for pediatric LIHR. Surgical techniques vary and are influenced by patient gender and age. The survey gives insights into demographics, case selection, and approaches among pediatric surgeons with regard to LIHR.
RESUMO
BACKGROUND: Axillary vein in the brachial tract or Basilic vein in the proximal third of the arm usually present a diameter wide enough to receive a catheter of 5 Fr. Therefore, a peripherally inserted central catheters with port (PICC-Ports) cannot be positioned in these areas. Pseudo-tunneling procedure allows the positioning of the Port in the middle part of the arm without using tunnelers during insertion of PICC with Port in patients who present deep veins of the arm too small to receive a PICC-Port catheter. The aim of this study was to present our experience with pseudo-tunneling procedure during the positioning of the PICC-Port, while using a particular variation of the technique already described for PICCs and midline. METHODS: From January to December 2023, 103 PICC-Ports were placed in adult patients. Ninety catheters were tunneled from the puncture of the axillary vein at the proximal arm point, while we used this new technique in 42 patients by the same trained team of Vascular Access Unit at ASST Spedali Civili Hospital of Brescia. RESULTS: All procedures were successfully performed at the first attempt. No insertion related complications were observed. CONCLUSIONS: Our data suggest pseudo-tunnelling is a safe and effective technique for PICC-Ports insertion avoiding central venous catheterization, even in patient with small vein at the arms.
RESUMO
Congenital internal jugular phlebectasia (CIJP) is a rare condition characterized by congenital dilatation of the vein without tortuosity that becomes more evident during straining as a lateral neck mass. CIJP often remains undiagnosed from a few months to several years after the onset of the swelling. It is frequently asymptomatic although symptomatic cases have been occasionally reported. We present the case of a healthy 7-year-old boy with a lateral neck mass, triggered by the Valsalva maneuver. Neck ultrasound (US) showed right internal jugular axial ectasia, increasing during the Valsalva maneuver; contrast computed tomography (CT) scan confirmed a fusiform dilatation of the right internal jugular vein. Due to the lack of symptoms, we treated our patient conservatively. At 5 years of follow-up, the patient is still asymptomatic, with no evidence of complications or thrombosis. Due to its self-limiting nature, treatment for asymptomatic cases of CIJP should be conservative, providing a follow-up with both clinical and US annual evaluations.
RESUMO
BACKGROUND: Pediatric renal cancer survivors have higher rate of chronic renal disease and hypertension. These patients have similar survival rates when treated according to either Children's Oncology Group (COG) or International Society of Pediatric Oncology (SIOP) protocols. We aimed to compare the late outcome of these two approaches. METHODS: We performed a meta-analysis of all studies from 2000 to 2021; database search using keywords: long-term outcomes OR late effects, nephrectomy, pediatric renal cancer. For each protocol, data were collected, and the "pooled" outcomes were compared. Continuous and dichotomous variables were obtained with a 95% odds ratio. RESULTS: Sixteen studies with a total of 715 pediatric renal cancer survivors were analyzed. The mean follow-up time was 17.4 (standard deviation 5.6) years. Reduced renal function and hypertension were the most encountered long-term complications. The mean estimated glomerular filtration rate was similar in both protocols (101.62 vs. 101.70 mL/min/1.73 m2), while the prevalence of hypertension was 23% in COG and 10% in SIOP. The prevalence of secondary malignancy was 1.1% in COG and 6.7% in SIOP (1.1% vs. 6.7%, p ≤ 0.001). Chronic kidney disease was similar in both groups. CONCLUSION: A high prevalence of hypertension was observed among pediatric renal cancer survivors, as well as an increased risk of a secondary tumor. These results emphasize the importance of long-term follow-up into adulthood, to promptly diagnose any long-term side effects of the treatment. Thanks to the increased overall survival, future protocols will pay attention to the reduction of long-term sequelae.

Aim: Video-assisted thoracoscopic surgery (VATS) has been widely used in the last decades. Nevertheless, the pros and cons of thoracoscopy vs. open surgery in pediatric oncology are still under debate. In literature, VATS has been applied for both diagnostic and ablative surgery to treat neurogenic tumors, thymic neoplasms, lung tumors and metastases, germ cell tumors, lymphoproliferative diseases, and other rare tumors. Recent reviews described excellent outcomes in pediatric oncology as well as in the treatment of adult lung cancer, with a significantly higher rate of mortality and complication in thoracotomy compared to VATS. We reviewed our experience on thoracoscopy in pediatric malignancy and compared it to the literature. Materials and Methods: This was a retrospective cohort-study of pediatric oncological patients who underwent VATS at our institution from 2007 to 2020, and a review of the recent literature on the topic. Results: A total of 43 procedures were performed on 38 oncological patients (18 males, 20 females). Median age was years 7.72 (0.35-18.6). Diagnosis: 10 neurogenic tumors, nine hematological diseases, five metastases, four lypoblastomas, three thymic pathologies, three germ cell tumors, two pleuropneumoblastomas, two myofibroblastic tumors, one myoepithelial carcinoma, one liposarcoma, and three suspected oncological mass. In three cases, a 3D model was elaborated to better plan the surgical approach. Diagnostic biopsies were 22 (51.1%), and ablative surgeries, 21 (48.9%). One neurogenic tumor was resected with the Da Vinci Robot. Median operative time was 120 min (30-420). A drain was left in place in 20 (46.5%) for a median of 4 days. Median length of hospitalization was 5 days (1-18). One case (2.3%) was converted (intraoperative bleeding). There were three post-operative complications (7.0%): one pneumonia, one pleural effusion, and one diaphragmatic paralysis (need for plication). Results were compared to recent literature, and morbidity and conversion rate were comparable to reviewed publications. Conclusion: VATS represents a valuable tool for diagnostic and therapeutic procedures in pediatric oncology. Nonetheless, it is a challenging technique that should be performed by expert surgeons on oncological and mini-invasive surgery. Three-dimensional reconstruction can optimize the pre-operative planning and guarantee a safer and more targeted treatment. Finally, the advent of robotics-assisted surgery represents a new challenge that may further implement the advantages of VATS.
RESUMO
Background: Lymphangiomas represent 5% of all benign pediatric tumors. Abdominal lymphangiomas (ALs) are extremely rare. Therapy includes surgery, sclerotherapy, or pharmacological treatment. Laparoscopic resection (LR) has been already described, but mainly as case reports. The aim of this study is to present our series of ALs LR. Materials and Methods: From 2007 to 2020, 10 cases of ALs were electively treated by LR. Patients' age ranged from 4 months to 14 years. Preoperative diagnosis was achieved by ultrasonography and magnetic resonance images. In all cases LR was performed with four trocars: a 10 mm transumbilical trocar for camera and extraction and three 3-5 mm operative trocars. Results: Lymphangiomas arise from mesocolon in 5 giant cases, ileal mesentery in 3 and right adrenal gland in 2. LR was achieved without intraoperative complications and need of conversion in all cases. Two giant cases needed a percutaneous puncture under laparoscopic view to gain working space. A minimal ileal resection by video-assisted procedure was carried out in 2. Median hospital length was 4 days; no recurrence of disease at serial ultrasound examinations was seen at median follow-up of 5.9 years. Discussion: Several approaches have been proposed for AL treatment. The main challenges are the huge dimensions, the difficulty to achieve a complete resection, and the risk of recurrence. In this series, elective LR of ALs resulted as feasible and effective, and we consider it the standard surgical therapy.

AIM: The use of robotics-assisted surgery in oncology has been proved effective and safe in adults. Despite these results, the use of robotics has been rarely reported for pediatric oncology. Our review aims to evaluate the safety and feasibility of robotics-assisted surgery in this field, analyzing our experience and performing a systematic review of the most recent studies. METHODS: We reviewed all patients affected by an oncological disease who underwent a robotics-assisted procedure at our institute. We performed a systematic review of the literature from 2012 to 2021 on the subjects. FINDINGS: A total of 14 patients underwent robotics-assisted tumor resection. Eleven procedures (median age 13.2-years old) were carried out in children with adnexal lesions (seven tumor excision and four ovariectomies). Histological diagnosis was mature teratoma (six), serous papillary cystadenofibromas of the fallopian tube (two), ovarian serous cystadenoma (one), ovarian mucinous cystadenoma (one), and ovarian seromucinous cystadenoma. The median length of stay was 2 days. No recurrences or complications at a median follow-up of 2.1-years were observed. A 5-year-old girl underwent a complete posterior resection of a type 3 sacrococcygeal tumor with a robotics-assisted approach for the dissection of a possible intraabdominal residual component of the lesion. No intra- and postoperative complications were recorded. Complete excision of a recurrent differentiating neuroblastoma of the left para-renal region was performed on a 9-year-old girl. An idiopathic anaphylactic shock occurred 1 day after the procedure. At 9 months' follow-up, no local recurrences of the lesion were observed. Overall, we reported no conversion to open surgery. Lastly, a robotic excision of a growing left superior mediastinal intermixed ganglioneuroblastoma was performed on an 8-year-old girl with no postoperative complications. Follow-up was uneventful (7 months). In the literature, the rate of complications ranges from 0 to 28%, mainly related to difficult dissection and impaired anatomy. Conversion is reported in 5% of all oncological procedures, due to more invading tumors and altered anatomical features. No robotics-related complications were reported. CONCLUSION: Robotics-assisted surgery in pediatric oncology has proven to be feasible. Nevertheless, its use should be limited to selected cases and performed by highly trained oncological surgeons. Preparation and patient positioning, alongside a correct port placement, are crucial to carrying out these procedures. Further innovations in robotics may allow a wider application of this technology in pediatric oncology.
