The accuracy of flexible spectral imaging colour enhancement for the diagnosis of gastric intestinal metaplasia
2014
Background Targeting biopsies on the basis of visual recognition of mucosal changes in the stomach instead of the currently accepted random biopsy sampling may be attractive. Aim The aim of this study was to evaluate the accuracy of endoscopic findings using flexible spectral imaging colour enhancement (FICE) for intestinal metaplasia (IM) in the gastric mucosa. Methods A consecutive cohort of 126 individuals aged over 50 years (27% men) was subjected to upper endoscopy using FICE. Histological assessment (per patient and per biopsy) was considered the gold standard to accuracy estimates. Results Histological assessment revealed IM in 50% of the individuals [OLGIM (operative link on gastric…
Unexplained neoplastic anastomotic recurrence after right hemicolectomy: a case report
2020
Abstract Background Anastomotic recurrences of the colon are postulated to arise due to inadequate margins, tumor implantation by exfoliated cells, altered biological properties of bowel anastomosis, and missed synchronous lesions. In this paper, a case of unexpected early local recurrence after surgery for colon cancer is presented. Case presentation A 68-year-old Caucasian man underwent right hemicolectomy for invasive G2 adenocarcinoma. Two months later, endoscopy revealed a wide and well-functioning anastomosis with a hyperemic, hard, and thickened mucosal area of about 2 cm in diameter. Biopsies showed the presence of an adenocarcinoma with the same grading of the previous lesion. Ten …
The Clinical Picture of Uncomplicated Versus Complicated Diverticulitis of the Colon
2007
Purpose There is no consensus about the correct definition of uncomplicated diverticulitis (UD) in clinical practice. We evaluated therefore whether clinical picture of UD differs from complicated diverticulitis (CD). Fifty consecutive eligible patients (21 males, 29 females, mean age 63.6 years, range 47–75 years) were studied. Symptoms, the inflammatory indices, and Computerized Tomography (CT) scan of the abdomen were assessed at the time of admission. Results Thirty-nine patients classified were affected by UD and 11 patients by CD. CD patients showed more severe clinical picture than UD and required urgent Hospital admission. Conversely, most of the patients affected by UD were treated…
Endoscopic Intracranial Craniofacial and Monobloc Osteotomies with the Aid of a Malleable High-Speed Pneumatic Drill: A Cadaveric and Clinical Study
2000
Endoscopic techniques are now an accepted part of the surgical armamentarium and are used routinely in a number of aesthetic and reconstructive procedures. Endoscopic techniques are now being used commonly by plastic surgeons in forehead and face lifts. In both craniofacial surgery and in neurosurgery, the application of endoscopy potentially allows the surgical team to perform wide dissection of the dura mater in a minimally invasive fashion, thereby potentially reducing the risk of dural and brain injury. Also reduced by this surgical approach is potential injury to the major venous structures, such as the sagittal sinus, along with overall reduced bleeding. After an extensive laboratory …
Endoscopic carpal tunnel release: results with special consideration to possible complications.
2000
Single-portal endoscopic carpal tunnel release (Agee technique) was carried out in 148 patients. Of these, 100 were examined clinically and electrophysiologically 1 day before surgery and 1 and 3 months thereafter. Ten patients experienced transient ulnar neuropraxia and two patients complained postoperatively of intense pain in the middle and ring fingers. Three patients suffered residual symptoms. In one of these an incomplete release of the distal portion of the retinaculum flexorum was suspected and later confirmed by magnetic resonance imaging. Another patient had applied for pension due to problems associated with a vertebral fracture in addition to his carpal tunnel symptoms. A third…

Endoscopic stenting for postoperative biliary strictures due to hepatic hydatid disease: effectiveness and long-term outcome.
2003
Background Postoperative strictures due to hepatic hydatid disease caused by Echinococcus surgery is considered to be a rare cause of benign bile duct strictures, especially in the Western world. Goals The aim of this retrospective study is to demonstrate possible characteristics of the strictures as well as the effectiveness of long-term endoscopic stenting. Study Between 1994 and 2001, we treated 10 of these cases in our clinic. All patients had surgery for hepatic Echinococcus disease one or more times. These types of benign biliary strictures, secondary to surgery of hepatic hydatid disease, were multiple and located in the proximal common bile duct. Endoscopic stent therapy was carried…
Minimally Invasive Management of Spontaneous Supratentorial Intracerebral Lobar Hemorrhages by a “Homemade” Endoscopic Strategy: The Evangelical Doct…
2019
Background Although the incidence of intracerebral hemorrhage (ICH) has appeared to be increasing over the years, its prognosis remains dismal. No consensus has yet been reached regarding the management of ICH; however, minimally invasive surgery should limit, if not avoid, intraoperative parenchymal damage. Therefore, we have presented a novel, modified “homemade” approach aimed to shorten the operative time and minimize the corticectomy and brain manipulation. Methods From 2008 to 2017, 53 patients (32 men and 21 women; mean age, 63.8 years) were admitted to our neurosurgery department and surgically treated for a lobar ICH. A modified suction tube, coupled with the endoscope light source…
Direct transnasal cholangioscopy with ultraslim endoscopes: a one-step intraductal balloon-guided approach.
2011
Background Direct cholangioscopy using an ultraslim endoscope is an attractive alternative to the conventional mother–baby endoscope system because it provides a single-operator platform and high-resolution image quality and allows advanced therapeutic interventions. However, biliary access is cumbersome and usually requires previous guidewire placement via retrograde cholangiography. Objective To evaluate the feasibility of a 1-step transnasal cholangioscopy (TNC) technique using an ultraslim endoscope with an intraductal balloon to maintain access without previous guidewire placement. Design Prospective, observational clinical feasibility study. Setting Single tertiary referral center. Ma…
Endoscopic dissection of dura and craniotomy with minimal trephines: a preliminary series.
1998
The first nine clinical cases using endoscopic dissection of dura and craniotomy with minimal trephines were performed from June to August 1997 after trial dissection of 19 fresh cadavers conducted at the University of Brno's Pathology Institute in the Czech Republic. These procedures involved the refinement of craniofacial and intracranial surgical techniques using the endoscope and prototype instruments. These dissections demonstrated that intracranial structures can be explored using an endoscope without encumbrance, and that major craniofacial surgeries may also be performed with minor incisions and minimal craniotomies. Furthermore, we seek to illustrate that use of the endoscope in cr…
