Secondary sclerosing cholangitis after long-term treatment in an intensive care unit: clinical presentation, endoscopic findings, treatment, and follow-up.

Background and study aims We present ten patients who developed secondary sclerosing cholangitis following long-term treatment in an intensive care unit (ICU) between 1999 and 2004. Patients and methods Ten consecutive patients who had no evidence suggestive of pre-existing hepatobiliary disease were admitted to an ICU because of trauma (n = 5), intracerebral hemorrhage (n = 3), or nonabdominal postsurgical complications (n = 2). All the patients had required treatment with long-term ventilation, catecholamines, total parenteral nutrition, and several antimicrobial agents. Results Cholestasis was first noted within 11 days after the initial insult. Endoscopic retrograde cholangiopancreatogr…

Confocal Laser Endomicroscopy for In Vivo Diagnosis of Early Squamous Cell Carcinoma in the Esophagus

Background & Aims: Confocal laser endomicroscopy has been shown to allow direct histologic imaging of gastrointestinal tumors in vivo. This study was designed to assess the potential of endomicroscopy for predicting histology in vivo during routine endoscopy in patients with early squamous cell cancer. Methods: Twenty-one consecutive patients with suspected early squamous cell cancer who had been referred for endoscopic therapy to a tertiary-care academic medical center were included in this prospective study. After staining with 0.5% Lugol's solution and injection of 500 mg fluorescein sodium, unstained mucosal areas were examined using confocal imaging. Images of each scanned lesion were …

Comparison of computed virtual chromoendoscopy and conventional chromoendoscopy with acetic acid for detection of neoplasia in Barrett's esophagus.

Background and study aims Computed virtual chromoendoscopy (CVC) is a new imaging technique that enhances mucosal surface contrast and highlights the vascular pattern without the need for dye-spraying as in conventional chromoendoscopy. The aim of this prospective randomized pilot study with a crossover design was to compare CVC with conventional chromoendoscopy with acetic acid (CAA) for the detection of high grade intraepithelial neoplasia (HGIN) or early cancer in patients with Barrett's esophagus. Patients and methods 57 patients with Barrett's esophagus (mean length 3.8 cm) and a history of HGIN/early cancer or suspected HGIN/early cancer were randomly allocated to undergo either CAA o…

Management of pre-malignant and malignant lesions by endoscopic resection

Endoscopic resection (ER) has gained more and more importance in the treatment of early gastrointestinal neoplasia over the last few years. The choice of the different available techniques depends on the site, the macroscopic type of the tumour and the personal experience of the endoscopist. The 'suck-and-cut' technique with ligation device or cap should be favoured to normal strip biopsy in the oesophagus because of the size of the resected specimen and its technical feasibility. A recently described method of ER in the stomach is the circumferential mucosal incision with a type of needle-knife and subsequent en-bloc resection following prior injection under the lesions. ER of high-grade i…

Prospective evaluation of the macroscopic types and location of early Barrett’s neoplasia in 380 lesions

The macroscopic appearance of early gastric cancers, classified according to the Japanese criteria, has been shown to be an important prognostic factor for local endoscopic therapy. No prospective data about the distribution of macroscopic types and their location in early Barrett's neoplasia are available, however. The present study was conducted to evaluate the clinical applicability of this macroscopic classification and to analyze the relative proportions of the different gross types in early Barrett's neoplasms and the correlation between the macroscopic classification and the stage or grade of differentiation.A total of 344 patients with 380 Barrett's neoplastic lesions who were refer…

Curative endoscopic therapy in patients with early esophageal squamous-cell carcinoma or high-grade intraepithelial neoplasia.

Background and study aims Endoscopic resection of esophageal squamous-cell neoplasia with curative intent is considered to be a safe and effective alternative treatment to radical surgery in cases where the neoplasia is intraepithelial or limited to the mucosal layer. These patients are at risk for recurrent malignancy in the preserved esophagus, however. We conducted a prospective study to evaluate the efficacy and safety of endoscopic resection and to analyze variables associated with recurrence in patients with mucosal or intraepithelial squamous-cell neoplasia. Patients and methods Between December 1997 and September 2005, 65 patients (mean age +/- standard deviation [SD] 62.9 +/- 9.5 y…

Invisible gastric carcinoma detected by random biopsy: long-term results after photodynamic therapy

Background and study aims Gastric cancer diagnosed from routine gastric biopsies without any evidence of a visible lesion and negative repeated biopsies is an infrequent but serious clinical problem for which gastrectomy has usually been recommended, even if operative specimens do not show cancer either. We report on a series of 22 such patients undergoing long-term follow-up after attempted treatment with photodynamic therapy (PDT). Patients and methods 22 patients with invisible gastric cancer (IGC) who presented during a 10-year period (10 men, mean age 56 +/- 15 years) were prospectively included. Initial histopathological findings confirmed by second opinion included 10 well-differenti…

Successful Endoscopic Resection of an Esophageal Metastasis from a Preceding Squamous-Cell Tonsillar Carcinoma

This report describes the case of a 62-year-old man with tonsillar carcinoma who had undergone esophagectomy due to an esophageal metastasis. Subsequently, a second metastasis occurred in the residual esophagus, and he presented for evaluation for local endoscopic therapy. The initial upper endoscopy revealed a type IIa - c lesion at 21 cm from the incisors, within a segment suspicious for Barrett's mucosa. As part of the complex treatment approach in this patient, endoscopic resection of the lesion was carried out using the suck-and-cut technique with ligation. Histology showed that the lesion was a metastasis from a squamous-cell carcinoma, with focal infiltration of the upper submucosal …
