Extraperitoneal kidney transplantation: a comparison between children weighting ≤15 kg and >15 kg. Experience of a single institution.

Extraperitoneal approach is sometimes recommended for kidney transplantation (KT) in children weighting <15 kg. We hypothesized that this approach might be as successful as in patients with normal weight. Data of all consecutive KTs performed between 2013 and 2019 were retrospectively reviewed. Early outcomes and surgical complications were compared between children weighing ≤15 kg (low-weight (LW) group) and those weighing >15 kg (Normal-weight (NW) group). All the 108 KTs were performed through an extraperitoneal approach. The LW group included 31 patients (mean age 3.5 ± 1.4 years), whose mean weight was 11.1 ± 2.0 kg. In the LW group,-a primary graft nonfunction (PNGF) occurred in one patient (3.2%), surgical complications occurred in nine (29%), with four venous thrombosis. In the NW group, PNGF occurred in one case (1.3%), delayed graft function (DGF) in eight (10%), surgical complications in 11 (14%) with only one case of venous thrombosis. In both groups, no need for patch during wound closure and no wound dehiscence were reported. The extraperitoneal approach can be effectively used in LW children. No differences were observed in the overall complication rate (P = 0.10), except for the occurrence of venous thrombosis (P = 0.02). This might be related to patients' characteristics of the LW group.

Pyogenic granuloma arising within capillary malformations in children: A case report and literature review.

Pyogenic granuloma (PG) is an acquired benign vascular hyperplasia. Even though PG is not so rare, its etiology is still unclear. Assuredly, an association between vascular anomalies and PG is an extremely rare finding, and a proper management of these cases is not well standardized to date. Herein, we report our experience with a giant PG arising spontaneously within a port-wine stain of the thorax. Previous cases reported in the pediatric literature and strategies of treatment are also discussed.

"Rendezvous" Procedure in Children with Cholecysto-Choledocholithiasis.

Introduction: Cholecysto-choledocolithiasis is a rare entity in children and its management is still challenging and controversial. The laparoendoscopic rendezvous (LERV) procedure, consisting of laparoscopic cholecystectomy and simultaneous endoscopic retrograde cholangiopancreatography for the management of symptomatic choledocholithiasis is well described in adult patients. However, in the literature, few reports about its application in the pediatric population have been recorded. Aim of the Study: The aim of the present study is to report our first successful cases of symptomatic cholecysto-choledocholithiasis LERV treatment. Methods: Two girls suffering of hemolytic disease presented to our third referral center with acute abdominal pain due to cholecysto-choledocholithiasis. Preoperative, perioperative, and postoperative data were retrospectively reviewed. Results: Surgery was performed without complications. The girls were dismissed once re-alimentation and re-canalization were achieved and had no other episodes of biliary cholic. Reported advantages of LERV include: a shorter in-hospital stay, a reduction in the number of procedures and anesthesia, and a reduced overall risk of complications. Conclusions: The promising result with our 2 cases suggest that, when performed in highly specialized centers, LERV is a safe procedure, which leads to considerable benefits, despite logistic and organizational difficulties.
