Safety and efficacy of frameless stereotactic robot-assisted intraparenchymal brain lesion biopsies versus image-guided biopsies: a bicentric comparative study.

Purpose: User-friendly robotic assistance and image-guided tools have been developed in the past decades for intraparenchymal brain lesion biopsy. These two methods are gradually becoming well accepted and are performed at the discretion of the neurosurgical teams. However, only a few data comparing their effectiveness and safety are available.

Radiographic growth rate as a predictor of aggressiveness of diffuse gliomas without 1p19q codeletion.

Objective: The 2021 WHO classification of CNS tumors has refined the definition of adult-type diffuse gliomas without 1p19q codeletion. Nevertheless, the aggressiveness of gliomas is based exclusively on histomolecular criteria performed on a limited sample of the tumor. The authors aimed to assess whether the spontaneous radiographic tumor growth rate is associated with tumor aggressiveness and allows preoperative identification of malignancy grade of adult-type diffuse gliomas without 1p19q codeletion.

Presentation and Management of Cerebral Venous Sinus Thrombosis After Supratentorial Craniotomy.

Background And Objectives: Cerebral venous sinus thrombosis (CVST) after supratentorial craniotomy is a poorly studied complication, for which there are no management guidelines. This study assessed the incidence, associated risk factors, and management of postoperative CVST after awake craniotomy.

Methods: This is an observational, retrospective, monocentric analysis of patients who underwent a supratentorial awake craniotomy.

Schwannomatosis: a Realm Reborn: year one.

Purpose Of Review: In 2022, an international consensus recommendation revised the nomenclature for neurofibromatosis type 2 ( NF2 ) and Schwannomatosis (SWN), now grouped under the umbrella term Schwannomatosis, and defined new diagnostic criteria.

Recent Findings: This review describes the molecular criteria for diagnosis of schwannomatosis and the subsequent diagnosis strategy, while setting out the most recent advances in our understanding of the natural history, pathology, molecular biology and treatment of schwannomatosis-associated tumors, including schwannomas, meningiomas and ependymomas.

Summary: Somatic mutation screening should become a new standard for the diagnosis of NF2 -, LTZTR1 -, SMARCB1 - and 22q-schwannomatosis to discriminate those conditions.

Predictors of postoperative epidural hematomas after custom-made porous hydroxyapatite cranioplasty: a single-center experience of 194 consecutive cases.

Cranioplasty is important for improving cosmesis and functional recovery after decompressive craniectomy. We assessed the incidence and predictors of post-cranioplasty epidural hematomas requiring surgical evacuation. A single-institution, retrospective study enrolled 194 consecutive patients who underwent a cranioplasty using custom-made hydroxyapatite between February 2008 and April 2022.

A Preoperative Scoring System to Predict Function-Based Resection Limitation Due to Insufficient Participation During Awake Surgery.

Background: Failure in achieving a function-based resection related to the insufficient patient's participation is a drawback of awake surgery.

Objective: To assess preoperative parameters predicting the risk of patient insufficient intraoperative cooperation leading to the arrest of the awake resection.

Methods: Observational, retrospective, multicentric cohort analysis enrolling 384 (experimental dataset) and 100 (external validation dataset) awake surgeries.

[Fibro-urothelial polyp in a horseshoe kidney in the case of Turner syndrome].

The authors report a case of fibro-epithelial polyp in a young woman with Turner syndrome with features of a right ureteropelvic junction syndrome in a horseshoe kidney. The patient presented a history of chronic low back pain associated with macroscopic haematuria leading to various complementary investigations including ureteroscopy. The endoscopic appearance of the tumour suggested the diagnosis despite the presence of atypical renal pelvis cytology.

Prosthetic reinforcement of varicose saphenous vein grafts for infrainguinal bypass.

Use of varicose saphenous veins for infrainguinal bypass is often contraindicated because of the risk of immediate rupture or long-term aneurysm. In this report we describe four cases in which prosthetic reinforcement allowed successful femoropopliteal bypass grafting using highly varicose saphenous veins while preserving normal endothelium. No thrombosis or any other complication was observed after a mean follow-up of 41 months.

[Malignant neuroendocrine tumor of the bladder: an entity not to be unrecognized].

The authors report a case of primary malignant neuroendocrine bladder tumour. This rare bladder tumour presents the morphological and immunohistochemical characteristic common to all neuroendocrine tumours observed in other organs. The urologist must recognise this histological entity, which requires multidisciplinary management.

[Recurrent febrile infections of the urinary tract and diverticulum of the urachus].

The urachus can present a partial or complete obliteration defect. If the defect is situated in its vesical extremity, it then forms a diverticulum. The authors report a case of diverticulum of the urachus in a young adult, responsible for recurrent febrile urinary tract infections since the beginning of adolescence.

[Percutaneous colposuspension with fixation to the suprapubic fibrous tissues].

Objectives: The authors conducted a long-term evaluation of a modification of the Peyrera-Raz procedure by creation of a fixed point in the suprapubic fibrous tissue.

Material And Methods: The authors report a series of 38 patients who, despite pelvi-perineal rehabilitation, presented urinary stress incontinence corrected by Bonney's manoeuvre. Treatment consisted of Peyrera-Raz percutaneous colposuspension modified by superior anchoring of the sutures to the suprapubic fibrous plane.

[Intradiverticular bladder tumors. Five case reports].

Objective: To define the diagnostic and therapeutic approach to intradiverticular bladder tumour.

Methods: Five cases are reported in which initial diverticulectomy was followed by cystectomy in one case, systemic MVAC chemotherapy in 2 cases and concomitant radiotherapy-chemotherapy (CRC) in 2 cases.

Results: One patient has died (MVAC), one patient is in partial remission (MVAC) and three patients are in complete remission (1 cystectomy and 2 CRC).

New experimental model of ureteropelvic junction obstruction allowing easy access for percutaneous surgery.

To assess the usefulness of an experimental model of ureteropelvic junction (UPJ) obstruction designed to facilitate subsequent percutaneous surgery, a right UPJ obstruction was created in 10 pigs by an open retroperitoneal surgical approach. With the pig in the left lateral decubitus position, a 0.038-inch Terumo guidewire was inserted via a 1-cm longitudinal upper-third ureterotomy and advanced up and down so as to bridge the UPJ from the flank to the urogenital opening.

[Dissecting aneurysm of the external iliac artery. An unusual course of endofibrosis in an athlete].

A 42-year-old man was consulted because of a pain in his left leg. He was a highly trained biker since 20 years. The echo-Doppler and arteriography evidenced a stenosis, probably due to endofibrosis of the external iliac artery.

Eversion of the rectum. A simplified technical approach to ileoanal anastomosis.

Eversion of the rectum allows complete excision of the rectum. Here, we describe a modification of the stapling technique of ileoanal anastomosis, which leads to a safer anastomosis.

[Hypothyroidism and immunotherapy using interferon or interleukin for metastatic renal adenocarcinoma].

The authors report a case of hypothyroidism occurring during cytokine treatment of metastatic renal cancer. This is a relatively rare complication of immunotherapy, whose aetiopathogenesis remains unclear. Possible hypotheses include an autoimmune process or direct toxicity.

[Laparoscopic drainage of a lymphocele after radical prostatectomy].

A laparoscopic procedure used to achieve transperitoneal drainage of a lymphocele that developed three months after radical prostatectomy for prostate cancer is described. The lymphocele wall was resected through a peritoneal opening. After drainage of the lymphocele, a corner of the omentum was inserted into the cavity.
