Mini-Laparoscopically Guided Percutaneous Gastrostomy and Jejunostomy
2003
Abstract Background: Percutaneous endoscopic tube placement can be problematic under certain circumstances: absence of transillumination of the abdominal wall, percutaneous jejunostomy in patients with a PEG tube and recurrent aspiration, enteral feeding access after gastrectomy, and obstruction of the upper GI tract. As an alternative in these problematic situations, a technique was developed for placing feeding tubes under visual control by using mini-laparoscopy. Methods: Placement of a feeding tube with mini-laparoscopy with the patient under conscious sedation was considered for 17 patients in whom standard PEG placement was impossible. Techniques used were the following: combined mini…
Prospective, cross-over, single-center trial comparing oral double-balloon enteroscopy and oral spiral enteroscopy in patients with suspected small-b…
2011
BACKGROUND AND STUDY AIMS: Spiral enteroscopy is a new, promising rapid enteroscopy technique. A prospective cross-over study was carried out to compare this new method with the established technique of double-balloon enteroscopy (DBE). PATIENTS AND METHODS: From an initial group of 18 patients with suspected mid-gastrointestinal bleeding due to vascular malformations but no previous history of small-bowel or colonic surgery, 10 patients (mean age 69 years) completed the study. Patients underwent both enteroscopy techniques with an oral approach, in a randomized sequence. The deepest point reached during advancement in the first enteroscopy was marked with India ink. The primary end point o…
Double-balloon enteroscopy (push-and-pull enteroscopy) of the small bowel: feasibility and diagnostic and therapeutic yield in patients with suspecte…
2005
Background Double-balloon enteroscopy (push-and-pull enteroscopy) is a new method that allows complete visualization, biopsy, and treatment in the small bowel. This study evaluated the feasibility and the diagnostic and the therapeutic yield of double-balloon enteroscopy (push-and-pull enteroscopy) in comparison with current imaging methods. Methods Between March 2003 and November 2004, 248 consecutive double-balloon enteroscopies (push-and-pull enteroscopies) were performed in a prospective study in 137 patients with suspected small-bowel disease (60 women, 77 men; mean age 56.6 ± 17.8 years), most with chronic GI bleeding (66%). The examinations were carried out after negative evaluations…
Hiatal hernia, gastro-oesophageal reflux and oesophagitis: videofluorographic, endoscopic and histopathological correlation
2004
The aim of the study was to evaluate the correlation between hiatal hernia and gastro-oesophageal reflux and related histological abnormalities in patients without endoscopic oesophagitis. A consecutive series of 78 patients with a history of gastro-oesophageal reflux symptoms and hiatal hernia, as defined by videofluorography combined with a water siphon test, underwent oesophagogastroduodenoscopy and multiple biopsies. Hiatal hernia was confirmed endoscopically in 99% of cases. The water siphon test was positive for reflux in 72% of cases. At endoscopy 42% of patients had oesophagitis and/or Barrett's oesophagus and 58% had no lesions. In the group without endoscopic lesions, at histology…
The supraorbital endoscopic approach for aneurysms.
2013
Objective To review our surgical experience in minimally invasive transcranial endoscope-assisted microsurgical treatment of intracranial aneurysms, using the supraorbital keyhole craniotomy. Methods The supraorbital keyhole approach was performed through an eyebrow skin incision in 793 cases for treatment of 989 intracranial aneurysms. Of patients, 474 were operated on after subarachnoid hemorrhage, and 319 were operated on under elective conditions. After lateral frontobasal burr hole trephination, a limited subfrontal craniotomy was created. To achieve adequate intraoperative exposure through the limited approach, endoscopes were used routinely. Surgical outcome was assessed using the mo…
P-POSSUM score: a prognostic instrument for postoperative complications in Crohn's disease
2018
The purpose of this work is to demonstrate the correlation between the p-POSSUM score and the severity of Crohn's Disease (CD) postoperative complications, evaluated by using the Clavien-Dindo score.We have selected data of 22 patients (11 males, 11 females) that had been recovered in the Operative Unit of General Surgery of the University of Palermo General Hospital and undergone surgery for CD from 2010 to 2017.Patients who underwent surgery for complicated CD was divided in three different group on the base of Clavien Dindo score, C1 (Clavien-Dindo ≤ 1), C2 (Clavien Dindo = 2), and C3 (Clavien Dindo ≥ 3). ANOVA one way statistic analysis was used to investigate the presence of statistic …
Endoluminal therapy of GERD with a new endoscopic suturing device
2005
Background Endoscopic, endoluminal therapy might be an alternative treatment option in light of the costs of proton pump inhibitor therapy and possible complications after laparoscopic surgery. The aim of the current study was to assess the efficacy and the safety of a new endoluminal suture device (ESD) in pig models and humans. Secondly, 3 and 6 months' follow-ups were performed, and possible complications and their management were evaluated. Methods In the preclinical phase of the study, suturing procedures were practiced and evaluated in 8 pig models (Erlanger Endo Trainer). In the clinical phase, 20 patients with mild esophagitis, small or no hiatal hernia, and signs of abnormal acid e…
Vocal function following laser and conventional surgery of small malignant vocal fold tumours
1996
AbstractIn the disecribed study, 26 patients after conventional, and 27 patients after laser cordectomy were examined six months or more after the operation. Videolarybogstroboscopy revealed that patients after laser cordectomy more often phonate on a purely glottic level (81 per cent) in comparison to patienbts after conventional cordectomy (19 per cent). Webs were more frequent and more extended after conventional cordectomy compared to endoscopic laser surgery. The maximal phonation time showed a very wide range with a mean value of 9 to 10 sec; there was no statistical difference between the groups of patients. Using yanagihara's classification of sonograms, a better voice quality was m…
[A gastric polypoid signet ring cell carcinoma]
2007
The authors signal a case of gastric polypoid signet ring cell carcinoma, of particular interest for its rarity like show from the review of the literature, which is the first to have been described after Tabaru's citation.The study has been carried out at the Department of Surgical and Oncological Sciences of the University of Palermo. It has been based on 2000 cases analysed from June 2001 to December 2003.The authors advance some and emphasizes the diagnostic flow chart and therapeutic choices adopted.We agree that the endoscopic polypectomy is surgical procedure of first approach, but modifying the therapeutic guideline in relation to histologic examination, like happened in the case in…
Endoscopic Neurosurgery and Endoscope-assisted Microneurosurgery for the Treatment of Intracranial Cysts
1998
Objective Different endoscopic techniques have been introduced into neurosurgery, but accepted terminology and definitions are still missing. We propose a terminology based on whether the endoscope is used alone or in conjunction with an operating microscope and on whether the route of surgical manipulations is through or outside the endoscope. Accordingly, procedures are categorized into endoscopic neurosurgery (EN), endoscope-assisted microneurosurgery (EAM), and endoscope-controlled microneurosurgery (ECM). Methods We treated 36 patients with intracranial arachnoid cysts (ACs) and intraventricular cysts endoscopically. The patients ranged in age from 4 months to 69 years (mean age, 31 yr…
