Percutaneous segmental dilatation of portal stenosis after paediatric liver transplantation to avoid or postpone surgery: two cases and literature review.

PURPOSE: The authors retrospectively reviewed the results obtained with percutaneous treatment of portal stenosis. MATERIALS AND METHODS: In November 2005 and March 2008, two patients, 15 and 32 months old, underwent portal vein angioplasty at our centre. Both procedures were performed after ultrasound-guided portal vein puncture and measurement of pre- and postanastomotic pressure gradients. The diameters of the angioplasty catheters ranged from 5 to 10 mm and no stents were used. RESULTS: In both cases, it was possible to cross the stenoses, perform angioplasty and obtain an immediate reduction of the pressure gradients. There were no major complications after the procedure. In the first patient, percutaneous treatment allowed us to postpone surgical revision of the anastomosis; in the second case, angioplasty had to be repeated twice over a period of 4 years to finally achieve regular patency of the anastomosis and function of the graft. CONCLUSIONS: Percutaneous treatment of portal stenosis after paediatric liver transplantation is a safe and feasible treatment; if balloon dilatation does not guarantee functional recovery of the organ, it allows surgical revision to be postponed to a later date when the clinical condition is more stable.

Penile injection of aedile silicone: A dangerous shortcut.

INTRODUCTION: The size of penis can cause concern in patients, even if the organ is clinically normal. Additionally, the cost of phosphodiesterase 5 inhibitors (iPDE5) and long waiting lists to access penile prosthesis placement can lead patients to resort to non-medical and potentially dangerous alternatives. One of these dangerous alternatives is the injection of building silicone at the level of the subcutis of the penis or the corpora cavernosa causing the formation of a granuloma that increases the girth and consistency of the penis. CASE REPORT: The article describes the case of a 43-year-old patient who self-injected aedile silicone at the level of his penis in an attempt to achieve greater penile size and greater rigidity. The patient reported that he could not economically afford the iPDE5.The persistence of severe pain in the penis forced the patient to go to a urological examination. The patient subsequently underwent the penile granuloma exeresis procedure and skin reconstruction with scrotal flap. CONCLUSION: The pursuit of sexual well-being can lead some patients to rely on unconventional and potentially harmful techniques. The role of the andrologist and of the scientific society should be to dissuade the patient from using these dangerous methods and to provide valid alternatives accessible to the patient. The economic difficulty in purchasing drugs that facilitate erection or the long waiting lists for the placement of penile prostheses can favor dangerous methods such as penile injection of silicon. There is therefore a clear need to facilitate access to drugs and surgical techniques that favor the patient's sexual well-being.

Cholangioscopic management of intrahepatic papillomatosis unsuitable for surgical treatment.

INTRODUCTION: Biliary papillomatosis can arise in any tract of the biliary three and is characterized by multiple papillary proliferation of the epithelial cells. CASE REPORT: A 65 year old woman was diagnosed been affected by biliary papillomatosis after many recurrent cholangitis episodes. Liver transplantation was excluded because of neoplastic degeneration with systemic involvement. After a percutaneous drainage and with palliative intent we performed an Argon plasma coagulation of the papillary lesions. DISCUSSION: Clinical behaviour consists of recurrent cholangitis episodes and obstructive jaundice. There aren't specific radiological features, only mucobilia observed during an ERCP is pathognomonic. Biliary papillomatosis grow according to the sequence adenoma-carcinoma with malignant transformation and poor prognosis due to multifocality and high recurrence rate. Radical surgery and liver transplantation represents the gold standard. Among palliative procedures must be considered percutaneous management with drainage and stenting, and intraluminal brachytherapy with I 192. CONCLUSION: We propose a palliative treatment with cholangioscopic Argon plasma coagulation of the biliary lesions that can be performed during a surgical exploration or a percutaneous management.
