Conservative Treatment of Splenic Haematoma After Colonoscopy: A Case Report
2020
Colonoscopy is a routine procedure performed worldwide, nevertheless, a small risk of splenic injury, often under-estimated, is still present. As a matter of fact, the diagnosis may be delayed, leading to a rising risk of morbidity and mortality. This paper describes a case of conservative treatment of colonoscopy-associated splenic injury. A 57-year-old woman presented with worsening pain in the upper left abdominal quadrant; she had radiation therapy to the ipsilateral subscapular region, and a diagnostic colonoscopy 18 hours earlier. The computed tomography (CT) scan revealed splenic laceration without signs of hemoperitoneum. Because of the hemodynamic stability of the patient, successf…
Three-dimensional hysterosonography for the study of endometrial tumors: comparison with conventional transvaginal sonography, hysterosalpingography,…
1997
We studied endometrial thickness and homogeneity in 36 patients with postmenopausal bleeding using three-dimensional ultrasound following distention of the uterine cavity with a sterile saline solution (3D-SHSG). Results with 3D-SHSG were compared with findings using transvaginal sonography, transvaginal sonohysterography, transvaginal color Doppler, and hysteroscopy. Sixteen patients (including three on tamoxifen) were undergoing hormone therapy at the time when they were studied. Visualization of the uterine cavity and of endometrial thickness was better with 3D-SHSG than with any of the other ultrasound techniques. The results with 3D-SHSG corresponded to the findings observed with hyste…
Ureteral injury during left colectomy for cancer: Laparoscopic management. A case report
2020
Abstract Introduction Iatrogenic ureteral lesions may occur after any abdominal and pelvic surgery. They are severe and can affect renal function and even vital prognosis. This study aimed to determine the clinical aspects and the therapeutic approaches of a lower third injury of the ureter during a laparoscopic left colectomy. Presentation of case An 81 year-old-man with left-sided colon cancer underwent laparoscopic left colectomy. During surgery there was a continuous full-thickness solution of the left ureter for which an end-to-end ureteral anastomosis was performed. In the postoperative period the patient underwent multiple urological and radiological interventional procedures due to …
Alterations in 18F-FDG accumulation into neck-related muscles after neck dissection for patients with oral cancers
2015
Background: 18 F-fluoro-2-deoxy-D-glucose ( 18 F-FDG) accumulations are commonly seen in the neck-related muscles of the surgical and non-surgical sides after surgery with neck dissection (ND) for oral cancers, which leads to radiologists having difficulty in diagnosing the lesions. To examine the alterations in 18 F-FDG accumulation in neck-related muscles of patients after ND for oral cancer. Material and Methods: 18 F-FDG accumulations on positron emission tomography (PET)-computed tomography (CT) in neck-related muscles were retrospectively analyzed after surgical dissection of cervical lymph nodes in oral cancers. Results: According to the extent of ND of cervical lymph nodes, the rate…
Massive glosso-cervical arteriovenous malformation: The rationale for a challenging surgical resection
2014
Massive arterivenous malformations (AVM) in the cervico-facial area are rare but potentially life-threatening. Treatment protocols are not well-established. A 41-year old man presented large painless rubber-like mass within the entire neck, which also extended intraorally through the floor of the mouth, showing a slow growing pattern for 5 years. Angiography diagnosed it as cervicofacial AVM. Treatment approach consisted on the embolization of the right upper thyroid, lingual and facial arteries under intravenous sedation. Three days later, bilateral radical neck dissection and subtotal glossectomy was performed. A musculo-cutaneous pectoralis major pedicled flap was harvested to reconstruc…
Robotic Versus Laparoscopic Staging for Early Ovarian Cancer: A Case-Matched Control Study.
2017
Abstract Study Objective To evaluate the feasibility, surgical outcome, and oncologic results observed after robotic staging compared with conventional laparoscopic staging for patients with early-stage ovarian cancer patients. Design A retrospective cohort study (Canadian Task Force classification II-2). Setting Catholic University of the Sacred Heart, Rome, Italy. Patients Ninety-six patients underwent minimally invasive staging for presumed stage I ovarian cancer; 32 underwent the robotic approach (cases), and 64 underwent the laparoscopic approach (controls). Measurements and Main Results There was no statistically significant difference between the 2 approaches with regard to final Fed…
Small bowel obstruction after caesarean section: Laparoscopic management. Two case reports
2020
Abstract Introduction Caesarean section is the most common abdominal surgery performed on women worldwide. Adhesions represent a severe complication of cesarean section and can cause different degrees of bowel obstruction. Case reports We report two unusual cases of small bowel obstruction treated with laparoscopic approach after caesarean section performed for gynecological pathologies. In the first one small bowel obstruction was due to volvulus caused by a severe pelvic adhesion syndrome; in the second one, occlusive picture was related to presence of multiple adhesion phenomena between the sigmoid colon and the right ovary as result of abdominal hysterectomy. Discussion The incidence of…
The European multicenter cohort study on cyanoacrylate embolization of refluxing great saphenous veins
2014
ObjectiveCyanoacrylate (CA) embolization of refluxing great saphenous veins (GSVs) has been previously described. The outcomes from a multicenter study are still lacking.MethodsA prospective multicenter study was conducted in seven centers in four European countries to abolish GSV reflux by endovenous CA embolization. Neither tumescent anesthesia nor postinterventional compression stockings were used. Varicose tributaries remained untreated until at least 3 months after the index treatment. Clinical examination, quality of life assessment, and duplex ultrasound evaluation were performed at 2 days and after 1, 3, 6, and 12 months.ResultsIn 70 patients, of whom 68 (97.1%) were available for 1…
Clinical and radiological outcome of arthrocentesis followed by autologous blood injection for treatment of chronic recurrent temporomandibular joint…
2017
Background This study was conducted to evaluate the functional outcome and MRI findings of arthrocentsis followed by autologous blood injection (ABI) into the joint space for management of chronic recurrent TMJ dislocation. Material and methods Total ten patients with bilateral chronic recurrent condylar dislocation were included in the study. Arthrocentesis of both TMJ was performed on each patient, followed by the injection of 2 ml of autologous blood into the superior joint compartment and 1 ml onto the outer surface of the joint capsule. Preoperative and postoperative assessment included; thorough history, clinical examination of TMJ, maximal mouth opening, frequency of dislocation, TMJ…
Cholesterol as stabilizer of the oxytocin receptor
2002
AbstractThe function of the oxytocin receptor system is strongly dependent on steroids as demonstrated by several physiological studies. One key element of this dependence on steroids may be the interaction of cholesterol and the oxytocin receptor. In this study, we show that cholesterol stabilizes the solubilized human oxytocin receptor against thermal inactivation and proteolytic degradation. In the absence of additional cholesterol, the soluble receptor inactivates within minutes. Maximal stabilization of the oxytocin receptor requires a continuous supply with cholesterol from a cholesterol-rich environment. A structure–activity analysis of various cholesterol analogues and their effect …
