RESUMEN
BACKGROUND: Treatment of high cryptorchidism can be challenging, often with frustrating results. We report 25 years of experience in the treatment of the cryptorchidism with very short spermatic vessels using an original two-stage orchiopexy that preserves the spermatic vessels. METHODS: We reviewed the clinical charts of children affected by cryptorchidism with very short spermatic vessels treated through our original surgical approach in tree Institutes of Pediatric Surgery. The first stage of the procedure started with an inguinal incision and a standard orchiopexy with a deep mobilization in the retroperitoneum to straighten the spermatic vessels that are entirely preserved. After realizing intraoperatively that such maximal retroperitoneal mobilization cannot ensure a satisfactory scrotal position of the testis, the spermatic cord is wrapped in a thin sheet of polytetrafluoroethylene (PTFE) shaped as a conduit. The testis is fixed to the bottom of the scrotum which remains invaginated due to the tension. [Fig. A - scheme of the operation]. This first stage can also be performed in laparoscopy, with a video-assisted positioning of the PTFE conduit [Fig. B - laparoscopic view with vessels and vas respectively marked by black and white arrows]. The second surgical stage is scheduled after 6-12 months to remove the PTFE conduit. RESULTS: A group of 100 children affected by cryptorchidism and very short spermatic vessels (9 bilateral, 86 intra-abdominal, 23 "peeping" at the internal ring) for a total of 109 testes underwent surgery with a two-stage procedure. From the first to the second stage, a progressive lowering of each testis towards the scrotum was observed. During the second stage, after removal of the PTFE sheet, the preserved cord was loose in the inguinal canal and all the testes were located in the scrotum: 68 testes were found correctly located with no further care needed, while 41 were still in a high scrotal position. However, the latter were easily detached from the scrotal bottom and re-fixed in a more satisfactory location. At 1-9 years follow-up all the testes but one (99%) were in the correct scrotal position with stable or increased testicular volume [Fig. C], while 1 testis vanished. No complications were observed all along the follow-up. CONCLUSIONS: This long term 25-year review indicates that our original surgical technique guarantees a high rate of success with neither evident contraindications nor drawbacks for patients affected by undescended testes with spermatic vessels so short to be untreatable through a standard orchiopexy.
RESUMEN
Pancreatic fluid collections (PFCs) are a well-known complication of pancreatitis. PFCs operative management includes percutaneous, endoscopic or surgical drainage. Even if in adult patients, endoscopic drainage is a well-established treatment, few data are available in pediatric setting. We report our single-center experience of EUS-guided cystogastrostomy and lumen-apposing metal stent (LAMS) positioning in children with PFCs; this, at the best of our knowledge, has never been reported before. All consecutive children with PFCs between April 2020 and November 2022 were enrolled in this retrospective study. PFCs were preoperatively evaluated with MRI or CT scan. All the procedures were performed under general anesthesia. A LAMS Hot-AxiosTM 10 × 15 mm was placed in all patients. We evaluated technical feasibility and clinical outcomes, including complications and recurrence rates. Follow-up included clinical observation, blood tests and US. EUS-guided cystogastrostomy was performed in 3 children (2 males; median age 13.2 years). Median maximum cyst diameter was 14.7 cm (range 10-22 cm). Technical and clinical success rates were 100%. No intra or post-operative complications occurred. Our experience suggests that this can be considered a safe and feasible treatment of PCFs even in the pediatric population, as long as the procedure is performed by an expert Endoscopist in a pediatric tertiary-level Center.
RESUMEN
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.
RESUMEN
BACKGROUND: Silicone Cuffed Centrally Inserted Central venous catheters (CICCs) were a type of catheters that have been used for a long time especially in cancer patients. Recently, thanks to biomedic research progresses, polyurethane catheters have resulted in higher surgical performances compared to classical silicone ones. Indeed, the inferior calibers of these new catheters lead to an extremely faster infusion rate. The presence of a valve at the tip of the catheter could suggest an impossible replacement procedure over a Seldinger guidewire. METHOD: The aim of this article is to explain our replacement technique over guidewire of silicone cuffed and valved tunneled CICCs with a power injectable polyurethane cuffed tunneled CICC. The casistic presented was evaluated at the Vascular Access Unit of ASST Spedali Civili in Brescia, Italy. The study involved 35 successful catheter replacement over guidewire, meanwhile cases where patients presented sepsis, exit site infection, or catheter damage were premeditatedly excluded. RESULTS: The maneuver was always conducted following the same procedure without noticing particular complications associated with CICC insertion. Indeed, the operation was quick, feasible, and safe. Septic, thromboembolic, or hemorrhagic complications also related to patients presenting dysfunctional coagulation cascade were not encountered. CONCLUSIONS: Our experience regarding the replacement technique of silicone cuffed and valved catheters over guidewire was considered feasible, accurate, and efficient for all patients treated, even in those presenting thrombocytopenia or a dysfunctional coagulation cascade.
