Gastrointestinal perforation: ultrasonographic diagnosis.
2013
Abstract Gastrointestinal tract perforations can occur for various causes such as peptic ulcer, inflammatory disease, blunt or penetrating trauma, iatrogenic factors, foreign body or a neoplasm that require an early recognition and, often, a surgical treatment. Ultrasonography could be useful as an initial diagnostic test to determine, in various cases the presence and, sometimes, the cause of the pneumoperitoneum. The main sonographic sign of perforation is free intraperitoneal air, resulting in an increased echogenicity of a peritoneal stripe associated with multiple reflection artifacts and characteristic comet-tail appearance. It is best detected using linear probes in the right upper q…
Secretory effect of azodisalicylate (azodisal sodium) on the short circuited mucosa of the rat ileum in vitro.
1988
Azodisalicylate (ADS) is one of the newly developed substitutes of sulphasalazine consisting of two molecules of 5-amino-salicylic acid. Azodisalicylate caused diarrhoea in some patients, apparently caused by an antiabsorptive secretagogue action of this compound. The mechanism of this was studied in the short circuited isolated mucosa of the rat ileum. Mucosal addition of ADS increased the potential difference (PD) and short circuit current (Isc) at a concentration of 1.3.10(-4) mol/l (4 mg/dl) with maximal effects at 1.3.10(-3) mol/l (40 mg/dl). Epithelial resistance was only slightly decreased at the higher concentrations of 40 and 100 mg/dl. Serosal ADS had no effect on electrical param…
Long-term outcome after urinary diversion using the ileocecal segment in children and adolescents: Complications of the efferent segment.
2016
Long-term outcomes are of special concern in children after urinary diversion. In a single institution study we evaluated retrospectively the long-term outcomes of urinary diversion in children, in whom the ileocecal segment had been used, in respect to complications of the efferent segment.The Mainz pouch was used in 107 children for continent urinary diversion. Indications were neurogenic bladder (53%, 57/107), exstrophy-epispadias complex (25%, 27/107), malignancy (13%, 14/107), and others (9%, 9/107). Continent cutaneous diversion was performed in 95 patients, and 12 patients received bladder augmentation/substitution with a continent cutaneous stoma. As efferent segment, we used the in…
ORTHOTOPIC BLADDER SUBSTITUTION IN WOMEN: FUNCTIONAL EVALUATION
1999
AbstractPurpose: Orthotopic bladder substitution following cystectomy in women has recently been introduced at some specialized centers. Studies of such a procedure should consider the oncological and functional outcomes. We analyzed only the functional results of orthotopic bladder substitution since followup is too short (about 2 years) for a valid oncological assessment.Materials and Methods: From October 1994 to November 1997, 60 women with a mean age of 48.3 years underwent standard radical cystectomy and orthotopic diversion (ileal W-neobladder with subserous tunnel in 47 and hemi-Kock reservoir in 13). The oncological criterion was organ confined invasive bladder cancer.Results: Ther…
Continent diversion with the Mainz pouch.
1996
From 1983 until July 1994, 561 patients in 2 urology departments (Mainz and Wuppertal) underwent a Mainz pouch 1 procedure. The Mainz pouch 1 was used for bladder augmentation in 60 patients, for orthotopic bladder substitution in 61 patients, and for continent cutaneous urinary diversion in 440 patients. In the group of continent cutaneous urinary diversion, the continence mechanism applied was an ileal intussusception nipple in 270 patients, an appendix stoma in 146 patients, a submucosal seromuscular bowel-flap tube in 14 patients, and a submucosal full-thickness bowel-flap tube in 10 patients. Indications for urinary diversion were bladder cancer in 339 patients, anatomical or functiona…
Benefits and Side Effects of Bandage Soft Contact Lens Application after LASIK
2005
Purpose To evaluate benefits and side effects of bandage soft contact lens (BSCL) insertion after LASIK in relation to patients’ characteristics. Design Prospective, randomized, bicenter comparative investigational trial. Participants One hundred patients (200 eyes) with myopia and/or myopic astigmatism. Methods Each patient underwent consecutive (Marburg, Germany) or simultaneous (Mainz, Germany) bilateral LASIK. At the end of the procedure, the first treated eye received a drop of ofloxacin and dexamethasone, patch, and transparent protective shield for 2 to 4 hours. The fellow eye received in addition a BSCL, soaked in the same eyedrops for 20 to 24 hours. Main Outcome Measures Schirmer …
Die Ileozökalscheide
1987
In 3 patients with vaginal aplasia respectively traumatic vaginal loss a neovagina was created out of the separated ileocecal segment. Advantages of this technique are the excellent blood supply of the ileocecal region and the long vascular pedicle. The additional application of terminal ileum for prolongation of the cecal vaginoplasty allows the tensionless anastomosis between neovagina and vulva even in patients with difficult anatomical conditions. The present paper gives a detailed description of the operative technique and the indications of the ileocecal vaginoplasty. Furthermore the common techniques for vaginal replacement are reviewed and discussed.
Vitamin B12 Deficiency in Children after Continent Urinary Diversion by Mainz Pouch Technique
2010
Purpose MAINZ pouch I urinary diversion provides a high-capacity, low-pressure reservoir. The use of terminal ileum can cause a decrease of vitamin B12 levels. Symptoms caused by vitamin B12 deficiency are rare, but some are irreversible, therefore annual check-ups are recommended. In this study the vitamin B12 levels in the above patients were analyzed in retrospect. Material and Methods The ileocecal segment was used for urinary tract reconstruction in > 80 children ≤17 years of age. B12 levels were determined at various time points within up to 21 years after surgery in 63 patients (8 with ileocecal bladder substitution, 55 continent cutaneous diversion). B12 values below 200pg/ml were c…
Anatomical basis for the interposition of a gastric pouch between the ileum and the anus after total proctocolectomy.
2003
After a total proctocolectomy, ileoanal continuity is achieved by an ileal pouch–anal anastomosis. This anastomosis is not possible when the ileum cannot reach the anus. To avoid definitive ileostomy in this circumstance, we devised a gastric pouch, taken from the left half of the vertical portion of the stomach, vascularized by the right gastroepiploic pedicle, then interposed it between the ileum and the anus. The aim of this anatomical study on seven cadavers was to estimate the capacity of this gastric pouch to reach the anus. The distance between the caudal edge of the pubic symphysis and the apex of the pouch was measured. It is accepted that an ileal pouch always reaches the anus wit…
Dynamics of gut mucosal and systemic Th1/Th2 cytokine responses in interferon-gamma and interleukin-12p40 knock out mice during primary and challenge…
2009
Cryptosporidium parvum is an intracellular parasite causing enteritis which can become life-threatening in the immunocompromised host. CD4+ T cells and interferon (IFN)-gamma play dominant roles in host immune response to infection. However, effector mechanisms that are responsible for recovery from infection are poorly understood. In the present study we analyzed mice deficient in IFN-gamma or interleukin (IL)-12 in parallel to C57BL/6 wild type mice as models for murine cryptosporidiosis. Our results identified IFN-gamma as the key cytokine in the innate as well as adaptive immunity during primary and also challenge C. parvum infection. Furthermore, both Th1 and Th2 cytokines appear to co…
