B‐Mode ultrasonography of the paranasal sinuses compared with CT findings
1992
Ultrasound as a diagnostic aid in the evaluation of the sinuses has been a controversial issue. Sensitivities have been reported from 29% to 100% and specificities from 55% to 99%. These wide variations in results from previous studies may have resulted from technical differences. However, the "gold standard" most often used for comparison has been a Water's view radiograph, which has been shown to correlate poorly with intraoperative and CT scan findings. To our knowledge, no one in the English language literature has evaluated sonography of the sinuses with computed tomography as the gold standard. In addition, evaluation of the ethmoid sinus has been neglected by previous studies that ha…
100 cases of Mainz pouch: continuing experience and evolution.
1988
The surgical technique for creation of the Mainz pouch uses 10 to 15 cm. of cecum and ascending colon and 2 ileal loops of the same length for construction of a urinary reservoir. Initial applications of the Mainz pouch were for bladder augmentation after subtotal cystectomy and for continent urinary diversion. Current indications have been extended to complete bladder substitution after radical cystoprostatectomy with anastomosis of the pouch to the membranous urethra. For cosmetic reasons the umbilicus is used as a stomal site for continent urinary diversion, and the technique of intussuscepting the continence nipple has been modified accordingly. A total of 100 patients underwent a Mainz…
Long-term follow-up of submucosal tunnel and serosa-lined extramural tunnel ureter implantation in ileocaecal continent cutaneous urinary diversion (…
2007
Authors from Mainz, Germany present the long-term follow-up of submucosal tunnel and serosa-lined extramural tunnel ureter implantation in the ileocaecal continent cutaneous urinary diversion first described in that department, called the Mainz-Pouch I. OBJECTIVE To assess upper urinary tract complications and renal function in patients with a submucosal tunnel and serosa-lined extramural tunnel ureter implantation during the long-term follow-up of ileocaecal continent cutaneous urinary diversion (Mainz pouch I). PATIENTS AND METHODS In all, 458 patients who had diversion with the ileocaecal pouch were analysed in a retrospective follow-up study. Uretero-intestinal implantation was done usi…
Non-Invasive Assessment of Coronary Artery Bypass Grafts and Native Coronary Arteries Using 64-Slice Computed Tomography: Comparison With Invasive Co…
2010
Introduction and objectives Although the diagnostic accuracy of CT in the non-invasive assessment of coronary arteries and grafts is known to be high, only a few studies have investigated the technique's reliability for the combined assessment of native coronary arteries, grafts, and vessels lying distal to anastomoses. The aim of this study was to evaluate the diagnostic accuracy of 64-slice CT for assessing coronary grafts and native coronary arteries. Methods In the study, 64-slice CT was used to evaluate 36 patients who had undergone coronary artery bypass graft surgery and had a clinical indication for angiographic graft assessment. The diagnostic accuracy of CT for identifying signifi…
Anastomotic leakage after colon cancer resection: does the individual surgeon matter?
2016
Aim Anastomotic leakage is one of the most feared complications after colonic resection. Many risk factors for anastomotic leakage have been reported, but the impact of an individual surgeon as a risk factor has scarcely been reported. The aim of this study was to assess if the individual surgeon is an independent risk factor for anastomotic leakage in colonic cancer surgery. Method This was a retrospective analysis of prospectively collected data from patients who underwent elective resection for colon cancer with anastomosis at a specialized colorectal unit from January 1993 to December 2010. Anastomotic leaks were diagnosed according to standardized criteria. Patient and tumour character…
Pyelotransverse pyelocolostomy: an alternative method for high urinary diversion in patients with extended bilateral ureter damage.
1991
After previous radiation due to pelvic malignoma or after multiple operations, the ileal conduit as well as sigmoid conduit are associated with an increased rate of complications. In these patients, the middle and distal ureter often cannot be considered for reimplantation due to fibrosis. High anastomosis to a bowel segment which is undamaged proves favorable. The transverse colon, conveniently situated in the cranial abdomen, is close enough to the kidneys for such a high anastomosis and is mostly spared from irradiation. In cases where severely damaged ureters forbid connection to a normal transverse conduit, we performed a pyelotransverse pyelocolostomy with high anastomosis of the bowe…
Permanent Stoma After Low Anterior Resection for Rectal Cancer
2010
BACKGROUND AND OBJECTIVES: A low anterior resection procedure for removing a rectal tumor aims to preserve the sphincter and avoid a permanent stoma. Permanent stomas are primarily necessary in cases of poor anorectal function and local recurrence. The aim of this study was to clarify whether anastomosis-related complications and local recurrence influenced the rate of permanent stomas in a long-term follow-up. METHODS: Of 1032 consecutive patients with rectal cancer, 397 were treated by low anterior resection (R0 and R1 resections) between 1985 and 2007 at the Department of General and Abdominal Surgery of the University Hospital, Mainz (Germany). All patient data were collected prospectiv…
Three-dimensional images contribute to the diagnosis of mucous retention cyst in maxillary sinus
2011
Objective: To evaluate the detection of mucous retention cyst of maxillary sinus (MRCMS) using panoramic radiography and cone beam computed tomography (CBCT). Study Design: A digital database with 6,000 panoramic radiographs was reviewed for MRCMS. Suggestive images of MRCMS were detected on 185 radiographs, and patients were located and invited to return for follow-up. Thirty patients returned, and control panoramic radiographs were obtained 6 to 46 months after the initial radiograph. When MRCMS was found on control radiographs, CBCT scans were obtained. Cysts were measured and compared on radiographs and scans. The Wilcoxon, Spearman and Kolmorogov-Smirnov tests were used for statistical…
Carcinoma of the hypopharynx and the cervical oesophagus: a surgical challenge.
1999
To report our results after reconstruction of the upper digestive tract for locally advanced carcinoma of the hypopharynx and cervical oesophagus.Open study.Teaching University hospital, Germany.Of the 517 patients who presented with carcinoma of the oesophagus between September 1985 and March 1997, 16 had a locally advanced tumour of the hypopharynx and 25 of the cervical oesophagus.Free jejunal grafts were used after circular resection in all patients with carcinoma of the hypopharynx, and for the 3 with oesophageal carcinoma in whom we obtained adequate resection margins. In the remainder stomach was used in 21 and colon in 1.Morbidity and mortality.After jejunal grafting 1 patient died …
Use of Bichat's buccal fat pad for the sealing of orosinusal communications. A presentation of 8 cases.
2011
Objectives: To determine the efficacy of the pediculate flap with the buccal fat pad in the sealing of orosinusal communications, describe the surgical technique used, and report the main complications. Patients and method: A retrospective study was made of 8 patients seen in the Service of Oral Surgery of the University of Barcelona Dental Clinic (Spain) for the treatment of orosinusal communications between the years 2007 and 2009. In all cases a pediculate flap with the buccal fat pad was used to solve the problem. Results: All of the orosinusal communications were successfully resolved with this technique. The immediate postoperative complications were pain (37.5%), inflammation (37.5%)…
