发现与治疗消化道病变,一直是内镜医师关注的焦点.1973年Dehle等[1]发明注射生理盐水切除结肠无蒂息肉的方法,1984年多田正弘等[2]首次将该技术用于诊治早期胃癌,并将之命名为“剥脱活检(Strip Biopsy)”,又称“内镜黏膜切除术( EndoscoMucosal Resection,EMR)”.此后,随着内镜技术的改进与器械的发明,EMR技术得到不断发展与创新,透明帽法、套扎器法、黏膜分片切除术等内镜下手术方式相继问世.但EMR切除病变的局限性和不完整性,促使着人们思考更新的技术去剥离更大、更完整的组织.1994年,Takeoshi等[3]发明了尖端带有陶瓷绝缘头的新型(Insulatedtip Knife,IT)电刀,它使医生对更大的胃肠道黏膜病变进行一次性完整切除成为可能. 相似文献

In patients with proliferative and mixed forms of total polyposis of the digestive tract the intestinal polyps are mainly localized in the duodenum, with hamartomal polyposis--in the jejunum and ileus. The endoscopic polypectomy from the small intestine may be performed intraoperatively and during endoscopy under narcosis. 174 polyps with the diameter of 0.5-5 cm were removed in 27 patients. There were 3 complications (bleedings) after polypectomy. 相似文献

Establishing a flexible sigmoidoscopy/colonoscopy program for surgical residents. The University of Illinois experience 总被引:2,自引:0,他引:2
The clinical value of lower gastrointestinal endoscopy and the requirement of the American Board of Surgery for endoscopic training mandate establishing a program in flexible sigmoidoscopy and colonoscopy for all surgical residents. In a 12-month period, the surgical residents at the authors' institution performed 599 flexible sigmoidoscopic and 116 total colonoscopic examinations under the supervision of two attending colorectal surgeons, with no mortality and a 0.03 per cent morbidity. There was an average of 42 endoscopic examinations per resident for the 3-week training period. Three hundred seventy (62%) of the flexible sigmoidoscopic examinations were for screening and 229 (38%) were for the evaluation of symptomatic patients. Colorectal polyps were identified in 68 patients (11.4%) and carcinoma in 14 patients (1.9%). Forty-nine per cent of the colonoscopic examinations were for endoscopic polypectomy. Sixty-four per cent of patients with more than one adenomatous polyp harbored polyps in different surgical segments of the colon. Every resident was able to perform flexible sigmoidoscopy safely by the end of the 3-week training period, and in addition, the residents rated their endoscopic experience as a valuable part of their surgical training. 相似文献

The article analyses experience in the treatment of 81 patients with diffuse polyposis who underwent subtotal resection of the colon with abdominoanal resection of the rectum and downward displacement of the right parts into the anal canal. It is shown that growth of the remaining occasional polyps and appearance of new polyps are encountered in the maintained parts of the colon and upper parts of the gastrointestinal tract in the postoperative period. The authors found that endoscopic polypectomy allows the right colon to be preserved in 92.6% of cases and the upper digestive tract in 97.5% of cases at a minimum risk of a surgical intervention. 相似文献

We have managed four cases of Peutz-Jeghers syndrome (PJS) in children. Fathers of three of these patients had PJS. There was also a family history of cancer in three cases, with pancreatic cancer in a father, colonic and laryngeal cancers in a grandfather, and hepatic and gastric cancers in a grandmother. It is presumed that in each of the cases, the largest polyp was responsible for initial symptoms. Preoperative examination revealed additional small polyps in the whole alimentary tract except for the oesophagus. Patients underwent laparotomy to remove the largest polyps and subsequent intraoperative endoscopic polypectomy for other small polyps, to minimize intestinal resection. Follow-up gastrointestinal examinations, including upper gastrointestinal series, small intestinal contrast study, and barium enema, were repeated about once a year. Three of four cases showed recurrent small intestinal polyps, and one required a second laparotomy because of recurrent abdominal pain. In conclusion, patients with PJS occurring in childhood have a strong hereditary family history of cancer and a high incidence of recurrence. Careful follow-up examination is mandatory for the gastrointestinal tract, as well as other solid organs that are susceptible to malignant change, throughout a patient's life. 相似文献

Background: Large colonic polyps present a particular challenge to endoscopists because of the risks of significant haemorrhage, perforation, inadequate polypectomy, or trying to snare an unrecognized cancer. The alternative to endoscopic therapy of large polyps is surgical resection and although minimally invasive techniques are available, risks are significant. Although neither surgery nor endoscopy is a perfect way of treating large colonic polyps, endoscopic resection is usually tried first. Most series of endoscopic polypectomies are small, include both rectal and colonic polyps and have varying size and shape criteria. The purpose of the present study is to describe a large consecutive series of colonic polyps evaluated endoscopically, to determine the chances of performing a safe, effective endoscopic polypectomy. Methods: All colonic polyps>20 mm in maximum dimension assessed during colonoscopy from 1989 to 2002 were reviewed. Rectal polyps were excluded. Demographic data for the patients were abstracted, as were data regarding the outcomes of polyp assessment and treatment. Primary end‐points were: the need for surgical resection, the incidence of postpolypectomy complications and the persistence of the index polyp at follow up. Independent variables included the endoscopically assessed size of the polyps, the year in which the polypectomy took place, the shape of the polyps and their location within the colon. Results: During the period under review 311 large polyps were removed from 252 different patients. Of these, 263 polyps were removed endoscopically and 48 polyps were removed surgically. An additional 18 endoscopically removed polyps ultimately needed surgery for recurrence or malignancy. There were no deaths but 19 complications of endoscopic polypectomy (17 late haemorrhage and two postpolypectomy syndrome). At first follow up, 22% of polyps had persisted, this decreased to 14% at second follow up and 7% at third. Complications were more common in right sided polyps and in flat or sessile lesions. Pedunculated polyps never persisted or recurred and had the lowest rate of surgery. Larger polyps had higher rates of advanced histology, complications, polyp persistence and the need for surgery. Conclusions: Polyp size, location and shape influence the results of endoscopic resection of large colonic polyps. Polyps>30 mm in maximum diameter are significantly more advanced histologically but also significantly more difficult to treat successfully than those <30 mm. However, size alone is rarely a contraindication to endoscopic resection. 相似文献

OBJECTIVE: Endoscopic treatment of large, sessile or awkward localized polyps, especially in the colon sigmoideum or the coecum holds the risk of colonic perforation. For these cases the combined colonoscopic-laparoscopic approach is described in this publication as an alternative procedure. PATIENTS AND METHODS: Since 1995 23 patients (male 11, female 12, age 70.7 +/- 12.0 years) were treated by laparoscopic-assisted colonoscopic polypectomy. Thirteen polyps were localized in the colon descendens or sigmoideum, seven in the cecum and one in the right respectively the left colonic flecture. Under general anesthesia and modified lithotomy position laparoscopy with occlusion of the colon or terminal ileum was followed by colonoscopy. After endoscopic localization the polyp was removed under laparoscopic visualization. During this procedure the colonic wall was stabilized, interfering adhesions were cut and coagulation- induced lesions of the wall were laparoscopically sutured if needed. RESULTS: In 17 patients the endoscopic polypectomy could be performed laparoscopically-assisted. In two patients the polypectomy was done by colotomy and in two others by segmental colonic resection due to the volume of the polyp. In two patients with histologically verified carcinoma laparoscopic-assisted left hemicolectomy was performed secondarily. Intra- or perioperative complications did not occur. CONCLUSION: Laparoscopic-assisted colonoscopic polypectomy is a new minimal-invasive therapeutical approach in selected cases with large, sessile or arkward localized polyps. The endoscopic procedure is possible also in polyps which should be treated by colotomy or segmental resection in the past. The additional discomfort for the patients due to laparoscopy is minimal. 相似文献
