Predelivery uterine arteries embolization in patients affected by placental implant anomalies.

PURPOSE: The aim of this study is to report on a single center experience of managing patients affected by placenta previa major and/or accretism by embolizing uterine arteries immediately before the cesarean delivery to reduce blood loss and secondary the rate of hysterectomies. MATERIALS AND METHODS: Sixty-nine patients have been prospectively enrolled. Inclusion criteria were radiological diagnosis of placenta anomalies and risk factors for peri/postpartum hemorrhage. The delivery was electively scheduled between the 35th week and the 36th week of pregnancy. The embolization procedure was performed in the gynecological operating room with a mobile C-arm by injecting calibrated microparticles 500-700 µm. A contrast-enhanced MRI was acquired in a subgroup of 10 patients 6 months after the delivery to evaluate the uterine wall status. RESULTS: Hysterectomy had been performed in 43.5%; 52.2% did not require blood transfusions; 1.2 blood units per patient had been meanly transfused. The mean fluoroscopy beam-on time was 195 s per patient. The mean uterine dose was 26.75 mGy. No pH anomalies were measured from the umbilical cord blood; the Apgar score at 5 min was ≥8. The analysis of the neuro-developmental milestones showed normal cognitive development in all children at 6 months. The uterine wall enhancement evaluated with contrast-enhanced MRI 6 months after the embolization procedure showed preserved myometrial perfusion without area of necrosis. CONCLUSIONS: In this series of patients, the predelivery uterine arteries' embolization was a safe and effective procedure; this may represent a technical alternative that interventional radiologists can consider when facing this challenging scenario.

Atraumatic splenic rupture in COVID-19 era: case report and systematic literature review.

Atraumatic splenic rupture is a rare but life-threatening condition. The Coronavirus disease 2019 (COVID-19) is still a mysterious infection, often associated with spontaneous bleeding and coagulation disorders. Among them, a rare presentation is the atraumatic splenic rupture during SARS-CoV-2 infection. We reported the case of a COVID-19 patient that underwent splenectomy for a spontaneous splenic rupture without splenomegaly or any hematological disorders. Moreover, we reviewed the literature about this matter focusing on the hypothetical etiopathogenesis of this condition in COVID-19 patients. Twelve cases of atraumatic splenic rupture without splenomegaly were reported in ten papers. Coughing, respiratory tract infections and anticoagulant treatment were postulated as the main risk factors for the spontaneous splenic rupture. COVID-19 is still a not well-known disease with multiple clinical presentations. The spontaneous splenic rupture is uncommon in general population but this event should not be neglected in this particular subset of patients.

It is really time to retire laparoscopic gastric banding? Positive outcomes after long-term follow-up: the management is the key.

After the initial widespread diffusion, laparoscopic adjustable gastric banding (LAGB) has been progressively abandoned and laparoscopic sleeve gastrectomy (LSG) has become the worldwide most adopted procedure. Nevertheless, recent reports raised concerns about the long-term weight regain after different bariatric techniques. Considering the large LAGB series recorded in our multicentric bariatric database, we analysed the anthropometric and surgical outcomes of obese patients underwent LAGB at a long-term follow-up, focusing on LAGB management. Between January 2008 to January 2018, demographics, anthropometric and post-operative data of obese patients undergone LAGB were retrospectively evaluated. To compare the postoperative outcomes, the cohort was divided in two groups according to the quantity of band filling (QBF): low band filling group (Group 1) with at most 3 ml of QBF, and patients in the high band filling group (Group 2) with at least 4 ml. 699 obese patients were considered in the analysis (351 in Group 1 and 348 in Group 2). Patients in Group 1 resulted significantly associated (p < 0.05) to higher % EWL and quality of life score (BAROS Score), 49.1 ± 11.3 vs 38.2 ± 14.2 and 5.9 ± 1.8 vs 3.8 ± 2.5, respectively. Moreover, patients with lower band filling (Group 1) complained less episodes of vomiting, epigastric pain and post-prandial reflux and significantly decreased slippage and migration rate (p < 0.001 for all parameters). LAGB is a safe and reversible procedure, whose efficacy is primarily related to correct postoperative handling. Low band filling and strict follow-up seem the success' key of this technique, which deserves full consideration among bariatric procedures.

The importance of patient selection in bariatric surgery: One not fit for all. Case report of a preventable double severe complication after Laparoscopic gastric banding positioning.

INTRODUCTION: Laparoscopic adjustable gastric banding (LAGB) is a minimal invasive, effective and reversible procedure, even if it is burdened by life threatening complications. PRESENTATION OF THE CASE: A 39 years-old female patient was admitted to our emergency department for abdominal pain and ileus and underwent an explorative laparoscopy. The LAGB was wrapped around the proximal portion of the stomach determining the erosion and ischemia of the great curvature region. It was removed and a large gastric resection of the great curvature was performed. Subsequently, a gastric leak with pleural abscess occurred with the beginning of the oral diet. It was successfully treated with fasting, intravenous antibiotics and a thoracic tube. DISCUSSION: LAGB is a restrictive procedure that compartmentalizes the upper stomach by placing a tight adjustable band around it. However severe and multiple complications can also occur. Slippage is one of the most frequent and dangerous complication. Partial gastric resection (comparable to sleeve gastrectomy) or total/subtotal gastrectomy on the limit of the scarring tissue is use requested in the latter case, with a high risk of postoperative leak. A strict postoperative follow-up is mandatory in order to early recognize any severe complications. CONCLUSION: Strict follow-up in this special subset of patients, the bariatric ones, is mandatory in order to early identify and correct any postoperative complications, avoiding severe sequelae.

Gastric perforation by intragastric balloon: Laparoscopic gastric wedge resection can be a strategy?

INTRODUCTION: IGB (Intragastric Balloon) is acknowledged to be a safe and secure device, whose outcomes in terms of weight loss are widely discussed. Bariatric community has soon noted tolerance and benefit of this tool, considered a first and easy step before bariatric surgery. Nevertheless, some authors have described a series of complications that, although rare, could be life threatening and hard to manage, as a gastric perforation. PRESENTATION OF CASE: We reported a case of a 55-year-old obese woman, undergone placement of IGB device heisting in a gastric perforation. In the same day of surgery, we performed an emergency, applying a combined endoscopic and laparoscopic approach, to remove the balloon and to close perforation by a gastric resection. DISCUSSION: Short term outcome was satisfactory, and the patient had a successful further follow up and weight loss. CONCLUSION: IGB is a valuable tool among bariatric procedure, nevertheless the surgeon has to consider the possible and life-threatening complications and to provide a multidisciplinary equip to face this occurrence.

The urokinase receptor-derived cyclic peptide [SRSRY] suppresses neovascularization and intravasation of osteosarcoma and chondrosarcoma cells.

The receptor for the urokinase-type plasminogen activator (uPAR) is a widely recognized master regulator of cell migration and uPAR88-92 is the minimal sequence required to induce cell motility and angiogenesis by interacting with the formyl peptide receptor type 1 (FPR1). In this study, we present evidence that the cyclization of the uPAR88-92 sequence generates a new potent inhibitor of migration, and extracellular matrix invasion of human osteosarcoma and chondrosarcoma cells expressing comparable levels of FPR1 on cell surface. In vitro, the cyclized peptide [SRSRY] prevents formation of capillary-like tubes by endothelial cells co-cultured with chondrosarcoma cells and trans-endothelial migration of osteosarcoma and chondrosarcoma cells. When chondrosarcoma cells were subcutaneously injected in nude mice, tumor size, intra-tumoral microvessel density and circulating tumor cells in blood samples collected before the sacrifice, were significantly reduced in animals treated daily with i.p-administration of 6 mg/Kg [SRSRY] as compared to animals treated with vehicle only. Our findings indicate that [SRSRY] prevents three key events occurring during the metastatic process of osteosarcoma and chondrosarcoma cells: the extracellular matrix invasion, the formation of a capillary network and the entry into bloodstream.

Incidence and pathological characteristics of prostate cancer in Italy: a contribution to the screening debate.

BACKGROUND: The scientific, social and financial aspects of prostate cancer (PC) organized or opportunistic screening to identify early PC are hotly debated. The incidence of prostate cancer is lower in Italy than in America and North Europe and data on PC incidence and pathological characteristics are scarce. METHODS: To determine PC incidence and whether screening would be beneficial, we studied 1008 consecutive symptomatic patients from the Southern Italy who underwent transrectal ultrasonography; 170 of them (age range: 48-93 years; median: 70 years) were at risk and underwent transrectal biopsy. RESULTS: Adenomatous hyperplasia was detected in 105 patients (62%), PC in 51 (30%), prostate intraepithelial neoplasia (PIN) in 5 (3%) and inflammatory disease in 5 (3%). The median age of patients with PC was 73.5 and tumors were generally well to moderately differentiated (76%, Gleason score < or =7). Prostate cancer (or PIN) was more frequent in patients over 70 (p<0.0001). The Gleason score also increased with age: >7 in 92% and 8% of patients aged >70 and < or =70, respectively (p<0.05). CONCLUSIONS: On the basis of our results organized or opportunistic PC screening of elderly men does not appear justified because: invasive carcinoma is detected in less than 1/3 of symptomatic "healthy" men; patients became symptomatic when their life expectancy is often less than 10 years; and PC is more frequent and more aggressive after 70 years.
