Impact of capsule endoscopy on prevention of postoperative recurrence of Crohn's disease.

Background And Aims: Capsule endoscopy (CE) can detect lesions outside the scope of ileocolonoscopy in postoperative patients with Crohn's disease (CD). However, the impact of such findings on patient outcomes remains unknown. This study is intended to evaluate the impact of CE findings on clinical management and outcomes in asymptomatic patients with CD without pharmacologic prophylaxis after ileocolonic resection.

Sedation With Propofol Has No Effect on Capsule Endoscopy Completion Rates: A Prospective Single-Center Study.

Patients who need both capsule endoscopy (CE) and colonoscopy often undergo both examinations on the same day to avoid repeated bowel preparation and fasting. Sedation can relieve pain and is commonly used for colonoscopies but may influence the CE completion rate.To determine whether sedation with propofol influences the completion rate and small-bowel transit time (SBTT) of CE.

Double balloon enteroscopy in the old: experience from China.

Aim: To evaluate the safety, efficacy and management of double balloon enteroscopy (DBE) carried out in those aged individuals with suspicious small intestine diseases.

Methods: DBE is a wonderful invention of the past decade and is widely used as an examination tool for the gastrointestinal tract. From January 2003 to July 2011, data from patients who were ≥ 65 years old and underwent DBE examination in the Nanfang Hospital were included in a retrospective analysis.

[Pit pattern and endoscopic mucosal resection in diagnosis and treatment of colorectal tumors].

Objective: To explore the effective methods to diagnose and treat colorectal cancer in its early stage.

Methods: 1 205 patients were examined by colonoscopy and mucosa staining with indigocarmine. The pit patterns were observed with magnifying endoscope and stereomicroscope according to the Kudo classification.

[The diagnosis and treatment of 25 cases of laterally spreading tumor of the large intestine].

Laterally spreading tumor (LST) originates from the large intestine mucosa with prominent lesions that mainly extend laterally other than vertically. The pathological morphology and evolvement of this disease distinguish itself from other adenomas, and its close association with colorectal cancer has been noted. Up till now, no report on LST involving the large intestine has been available in China, therefore we presently report our experience in the diagnoses and treatment of 25 LST patients (26 lesions) identified with conventional endoscopy and mucosa staining during the period from Nov, 2000 to Oct, 2001.

[Construction and application of colorectal polyp database].

Objective: To study the construction and application of computerized database of colorectal polyp in the clinical management and research of this disease.

Method: A colorectal polyp database and its management system was constructed on the basis of Microsoft Access 2000. Clinical, endoscopic and pathological data, which went through standardized and elemental processing, of 2 627 cases (4 850 records) of colorectal polyp collected from 1990 to 2000 in Nanfang Hospital was entered into this database.

[Endoscopic diagnosis and treatment of the early-stage malignant colorectal polyp and follow-up study].

In the past 20 years we have performed endoscopic removal of colorectal polyps in 4 000 cases, and thorough histological examination of the removed polyps identified 121 cases of early-stage malignant polyp. According to the depth of malignant invasion and whether malignant remnants were present after the initial surgical removal, conservative treatment or radical operation was implemented. During the follow-up study, endoscopy was performed once each year in all the patients with malignancies.

[Serrated adenoma of large intestine: report of 7 cases].

From December 2000 to April 2001, 859 patients were examined with coloscopy in our endoscopy centre and 188 cases of adenoma were diagnosed. Among the 188 patients, 7 were found with serrated adenoma that had been confirmed pathologically, including 6 male and 1 female patients, aged 32 to 53 with an average of 44.7 years.

[Comparison of curative effect for colon flat lesion between mucosa resection and fulguration with high frequency current after mucosa staining under magnifying endoscope].

Objective: To observe the relationship between the pit patterns and pathology and compare the curative effect for colon flat lesion between endoscopic mucosa resection (EMR) and fulguration with high frequency current (FHFC).

Methods: They were divided to two groups. There were 37 cases for FHFC in group A, and 34 cases for EMR in Group B.
