Bowel ultrasonography in acute abdomen: beyond acute appendicitis.
2021
Acute abdomen is a common reason for consultation in the emergency department. A broad spectrum of entities, including diverse diseases of the gastrointestinal tract, can cause acute abdomen. Although computed tomography is the technique most widely used to evaluate acute abdomen in the emergency department, abdominal ultrasound is often performed first and allows bowel disease to be suspected. This article describes the ultrasound features of diverse bowel diseases that can cause acute abdomen, such as acute diverticulitis, bowel obstruction, gastrointestinal perforation, bowel ischemia, intraabdominal fat necrosis, and miscellaneous processes such as endometriosis, foreign bodies, or vasc…
Long-Term Efficacy of Radiofrequency Treatment of Turbinate Hypertrophy: A Patient Based Point of View
2010
Nasal turbinate hypertrophy is a major cause of nasal airway obstruction that affects up to 20% of the European general population. This study aims to determine the efficacy of radiofrequency treatment as perceived by patients during a 2-years period. From 2007 to 2009, an observational study was conducted on 36 patients who consecutively underwent temperature-controlled radiofrequency tissue volume reduction. A questionnaire was administered to each patient in order to collect demographic data, lifestyle habits, health status and visual analogue scale (VAS) score of perceived symptoms. Mean VAS scores of nasal obstruction, headache, rhinorrhoea and anosmia after treatment were significantl…
Oropharyngeal Hairy Polyp: A Case of Respiratory Failure in a Newborn
2020
Hairy polyps, also known as dermoid polyps (DPs), are rare benign cystic lesions of bigerminal origin that may occur in several head and neck regions, including the oropharynx. Despite their benign histopathological nature, DPs may be life threatening, due to their upper airway location, and DPs represent one of the most unusual causes of respiratory distress during the neonatal period. In this paper, we describe a case of respiratory failure in a newborn with an oropharyngeal mass that was accidentally found during difficult intubation. Magnetic resonance imaging (MRI) detected a well-defined soft tissue pedunculated mass, arising from the left oropharynx wall, consistent with an oropharyn…
Detection of Subpubic Tumor Causing Bladder Outlet Obstruction by 3D Perineal Ultrasound
2015
This case report shows that 3D perineal ultrasound can be superior to clinical examination and routine 2D perineal ultrasound in the detection of an unusual subpubic tumor. A 73-year-old female patient was referred to our urogynecological outpatient unit complaining of over-active bladder symptoms and voiding dysfunction for 3 years. Gynecological examination found no signs of pelvic organ prolapse or abnormality in the vaginal cavity. Routine 2D perineal ultrasound showed substantial residual urine (ca. 300 ml on catheter) and limited bladder neck mobility, but no signs of pelvic organ prolapse. Use of standardized 3D perineal ultrasound revealed a 24 × 26 × 32 mm spherical, hypoechoic tum…
Effects of a low-power He-Ne laser on the healing of experimental colon anastomoses: our experience
1992
Despite technical advances, the incidence of anastomotic leaks in elective colorectal surgery remains around 14%. Recent studies suggest that the use of low-energy lasers may enhance wound healing in different tissues in a selective, nondestructive manner. Based on these findings we have attempted to provide experimental background on the effects of a He-Ne laser during the early stages of healing in 155 colonic anastomoses performed on rats. The irradiation (external or endoscopical) ofthe anastomoses by repeated doses below 4 J/cm 2 suggest (1) the laser-induced enhancement of anastomotic healing can be obtained in both healthy colons or in situations in which anastomotic breakdown is mor…
Evaluation von Nierenarterienstenosen: Vergleich von Angiographie mit invasiver Blutdruckmessung und Doppler-Sonographie
2000
Ziel: Der bei einer Nierenarterien-Angioplastie angiographisch gemessene Stenosegrad soll mit dem transstenotischen Blutdruck-Gradienten und dem prainterventionellen dopplersonographischen Befund verglichen werden. Methoden: Anhand von insgesamt 46 Nierenarterienstenosen bei 35 Patienten mit renovaskularer Hypertonie werden die angiographisch-morphologischen Befunde („linearer”, „geometrischer” und „densitometrischer” Stenosegrad) mit der invasiven transstenotischen Blutdruckmessung und den prainterventionellen Doppler-Befunden verglichen. Ergebnisse: Alle angiographisch bestimmten Stenosegrade korrelieren - masig - mit den transstenotischen Druckgradienten (Korrelationskoeffizienten: 0,67 …
Airway assessment by four-phase rhinomanometry in septal surgery
2011
PURPOSE OF REVIEW This article updates the state of the art in functional ventilation tests of the nasal airway. Multidisciplinary international cooperation has led within the last years to the development of four-phase rhinomanometry (4PR) by eradicating the errors of the 'classic' rhinomanometry. RECENT FINDINGS Physical experiments, mathematical models and comprehensive statistical analyses implicate that the nasal breath consists of four phases of different diagnostic importance. Presuming the motility of the nasal entrance, it is necessary to depict the elastic behavior within the rhinomanometric curve, as well as to use new parameters for the clinical evaluation of the nasal obstructi…
Medical treatment for inoperable malignant bowel obstruction: a qualitative systematic review.
2007
The use of symptomatic agents has greatly improved the medical treatment of advanced cancer patients with inoperable bowel obstruction. A systematic review of studies of the most popular drugs used in the medical management of inoperable malignant bowel obstruction was performed to assess the effectiveness of these treatments and provide some lines of evidence. Randomized trials that involved patients with a clinical diagnosis of intestinal obstruction due to advanced cancer treated with these drugs were reviewed. Five reports fulfilled inclusion criteria. Three studies compared octreotide (OC) and hyoscine butylbromide (HB), and two studies compared corticosteroids (CSs) and placebo. Globa…
Small bowel volvulus due to a large intestinal lipoma: A rare case report
2020
Highlights • These are rare, benign, slow-growing mesenchymal tumors originating from adipose tissue in the bowel wall. Lipomas of mesentery, mesocolon, and antimesenteric side of intestine are extremely rare. • We describe a case of small bowel obstruction secondary to volvulus due to an antimesenteric ileal lipoma. • Mesenteric lipomas are rare clinical entity, with less than 50 cases described in English language literature. CT scan is the gold standard imaging modality for diagnosis of mesenteric lipoma and other lipomatous abdominal masses. • It shows homogenous tumor of adipose tissue, gives information about features of the small bowel and if there is evidence of ischemia and can dem…
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…
