Vasculitis of the bladder: An extremely rare case report

AbstractINTRODUCTIONIsolated vasculitis of the bladder is extremely rare. The main causes of which are auto-immune diseases and occasionally infections. Corticosteroid therapy plays a central role in treatment in the majority of cases.PRESENTATION OF CASEWe report a case of gross hematuria associated with irritative low urinary tract symptoms (LUTS) and an increase of biological parameters of inflammation. Radiologic studies suspected a pelvic tumor process. We performed a cystoscopy with multiple biopsies. The pathological findings of the chips were in favor of a thrombotic nongranulomatous vasculitis of small and medium caliber. In view of these findings, all systemic diseases and inflammatory diseases such as cryoglobulinemia, the anti-phospholipid syndrome, Crohn's disease were eliminated. The symptoms regressed completely under antibiotics and anticoagulants.DISCUSSIONOur treatment options were based on the extent of the acute phase reaction and the pelvic venous thrombosis. A few similar cases have been reported in the literature, particularly a case of isolated necrotizing vasculitis of the bladder involving small vessels with a mild laboratory acute phase reaction which was treated with corticosteroids and cyclophosphamide.CONCLUSIONIt is important to differentiate this rare pathological feature of the bladder from other bladder tumors as the treatment is medical rather than surgical

Pneumatosis cystoidis intestinalis presenting as bowel perforation, a rare entity

AbstractIntroductionPneumatosis cystoides intestinalis (PCI) is an uncommon condition. This following article describes a case of primary PCI presenting as acute abdomen due to perforation of a small bowel cyst.Presentation of caseThis following article describes the case of an 88 year-old woman admitted at the hospital with peritonitis and consequently operated for a presumed bowel ischemia and perforation. However surgical exploration revealed perforated PCI.DiscussionThe pathophysiology of secondary PCI is poorly understood. Gas produced by Gas-forming bacteria may enter the mucosal barrier due and consequently this gas accumulates within the bowel wall. Also malnutrition can prevent the digestion of carbohydrates, which leads to increased bacterial fermentation, and production of large volumes of gas leading to distention and ischemia and subsequently the submucosal dissection of gas. Colonoscopy is helpful in excluding other colonic lesions and it shows the submucosal cysts that have a typical dual appearance: multiple white small cysts coupled to a sub-atrophic mucosa or larger cysts (up to 3cm) with a reddened overlying mucosa.ConclusionThe treatment unless complicated should be conservative even in the presence of pneumoperitoneum, after excluding complications

An analysis of surgical anatomy of the gastric fundus in bariatric surgery: Why the gastric pouch expands? A point of technique

AbstractIn bariatric surgery, it is essential to completely release the Fundus in order to create a narrow gastric pouch. The upper part of the fundus is located above the omental bursa and is therefore retro-peritoneal. In order to release this completely, not only does the arterial supply to the fundus need to be divided to visualise the left diaphragmatic pillar, but the right attachment beginning at the left diaphragmatic pillar and running towards the fundus needs to be divided. This minimal dissection is compensated by further dissection at the level of the left diaphragmatic pillar and traction on the stomach from right to left during the final division stapling division process. The surgeon still has the impression of having released the posterior aspect of the Fundus, exposing the pillar of the diaphragm, although in fact part of the Fundus still remains adherent to the diaphragm and is therefore not released

First Characterization with Ultrasound Contrast Agent of a Fibrovascular Polyp Before Its Endoscopic Resection: A Case Report (with Videos)

We described for the first time the contrast enhancement of a giant fibrovascular esophageal polyp using ultrasound contrast agent, Sonovue® (Bracco, Milan, Italy) during echoendoscopy. Fine Doppler was unsuccessful in showing vascularization due to the mobile characteristic of the tumor. In contrast, via Sonovue®, tissue microcirculation was highlighted inside the entire head of the polyp, leading to better appreciate the risk of bleeding related to its resection. In a second part, we showed the feasibility of classic polypectomy for this giant polyp (5×5 cm) without complication and results of control endoscopy at 3 months. The present case is summarized in a video

Postoperative Pancreatic Fistula. Is Minimally Invasive Surgery Better than Open? A Systematic Review and Meta-analysis

Background/Aim: Minimally invasive pancreatico-duodenectomy (PD) is gaining popularity. The aim of this study was to compare the incidence of postoperative pancreatic fistula (POPF) after minimally invasive versus open procedures. Materials and Methods: Following the PRISMA statement, literature research was conducted focusing on papers comparing the incidence of POPF after open pancreaticoduodenectomy (OPD) versus minimally invasive pancreaticoduodenectomy (MIPD). Results: Twenty-one papers were included in this meta -analysis, for a total of 4,448 patients. A total of 2,456 patients (55.2%) underwent OPD, while 1,992 (44.8%) underwent MIPD. Age, ASA score III patients, incidence of pancreatic ductal adenocarcinoma and duct diameter were significantly lower in the MIPD group. No statistically significant differences were found between the OPD and MIPD regarding the incidence of major complications (15.6% vs. 17.0%, respectively, p=0.55), mortality (3.7% vs. 2.4%, p=0.81), and POPF rate (14.3% vs. 12.9%, p=0.25). Conclusion: MIPD and OPD had comparable rates of postoperative complications, postoperative mortality, and POPF

Brain alterations associated with overweight evaluated by body mass index or body fat index in an elderly population: the PROOF study

Background/objectivesObesity is a complex health issue in which the brain plays a role yet to be determined, especially in the elderly. Indeed, in the ageing population, the balance between fat and lean mass is different; thus, the co-influence between the brain and obesity may differ between the elderly and younger subjects. Our main goal is thus to explore the relationship between the brain and obesity using two different approaches to measure obesity: body mass index (BMI) and an index centred on fat mass, the body fat index (BFI).Subjects/methodsAmong the 1,011 subjects of the PROOF population, 273 subjects aged 75 years underwent 3D magnetic resonance imaging as well as dual-energy X-ray absorptiometry to assess fat mass. Voxel-based morphometry was used to explore the local differences in brain volume with obesity.ResultsHigher BMI and BFI were associated with higher grey matter (GM) volume in the left cerebellum. Higher BMI and BFI were mainly associated with higher white matter volume in the left and right cerebellum and near the right medial orbital gyrus. Higher BMI was also associated with higher GM volume in the brainstem, whereas higher BFI was associated with higher GM volume in the left middle temporal gyrus. No decrease in white matter was associated with BMI or BFI.ConclusionIn the elderly, the relationship between the brain and obesity does not depend on the marker of obesity. Supra-tentorial brain structures seem to be slightly associated with obesity, whereas the cerebellum seems to be one of the key structures related to obesity

Best practice approach for redo-surgeries after sleeve gastrectomy, an expert's modified Delphi consensus

Background: Sleeve gastrectomy (SG) is the most common metabolic and bariatric surgical (MBS) procedure worldwide. Despite the desired effect of SG on weight loss and remission of obesity-associated medical problems, there are some concerns regarding the need to do revisional/conversional surgeries after SG. This study aims to make an algorithmic clinical approach based on an expert-modified Delphi consensus regarding redo-surgeries after SG, to give bariatric and metabolic surgeons a guideline that might help for the best clinical decision. Methods: Forty-six recognized bariatric and metabolic surgeons from 25 different countries participated in this Delphi consensus study in two rounds to develop a consensus on redo-surgeries after SG. An agreement/disagreement ≥ 70.0% on statements was considered to indicate a consensus. Results: Consensus was reached for 62 of 72 statements and experts did not achieve consensus on 10 statements after two rounds of online voting. Most of the experts believed that multi-disciplinary team evaluation should be done in all redo-procedures after SG and there should be at least 12 months of medical and supportive management before performing redo-surgeries after SG for insufficient weight loss, weight regain, and gastroesophageal reflux disease (GERD). Also, experts agreed that in case of symptomatic GERD in the presence of adequate weight loss, medical treatment for at least 1 to 2 years is an acceptable option and agreed that Roux-en Y gastric bypass is an appropriate option in this situation. There was disagreement consensus on efficacy of omentopexy in rotation and efficacy of fundoplication in the presence of a dilated fundus and GERD. Conclusion: Redo-surgeries after SG is still an important issue among bariatric and metabolic surgeons. The proper time and procedure selection for redo-surgery need careful considerations. Although multi-disciplinary team evaluation plays a key role to evaluate best options in these situations, an algorithmic clinical approach based on the expert's consensus as a guideline can help for the best clinical decision-making.info:eu-repo/semantics/publishedVersio
