ABSTRACT
<p><b>OBJECTIVES</b>To investigate the value of colonoscopy for the diagnosis and preoperative staging of colorectal cancer, and evaluate the significance of correct preoperative staging in guiding treatment.</p><p><b>METHODS</b>28 patients with colorectal cancer were examined by general colonoscopy, magnifying endoscopy and endoscopic ultrasonography before operation. Preoperative staging, and proper treatment protocols were made.</p><p><b>RESULTS</b>Endoscopy revealed that 15 of the 28 patients had early colorectal cancer and 13 advanced colorectal cancer. The correct diagnosis rate for preoperative staging was 100%; the accuracy of penetrating depth was 89% (25/28). In the early cases, tumour invasion was confined to mucosal layer in 11 patients and submucosal layer in 4. Six patients with early cancers 6 cm from the anus were treated by endoscopic mucosa resection (EMR) or EMR combined with open surgery. No postoperative recurrence was found by endoscopy during the period of follow-up for 12 - 40 months.</p><p><b>CONCLUSION</b>Correct preoperative staging for colorectal cancer is of important significance in guiding treatment, especially in early staging cases. In order to improve the quality of life for colorectal cancer patients, we should treat them with individualized operation based on curative resection.</p>

Objective To summarize the experience of the use of drainage after radical resection for rectal carcinoma.Methods 87 cases of patients who underwent radical resection for rectal carcinoma from May 1996 to May 2000 were reviwed retrospectively.Results Among 40 cases who underwent abdominoperineal resection(APR),perineal wounds were healed at one stage in 37 case,perineal wound infections occurred in 3 case,bleeding in one case and bowel obstruction in one case.among the other 47 cases who underwent low anterior resection(LAR),intrapelvic infection occurred in one case,anastomosis leakage occurred in one case.Conclusions The use of drainage after radical resection for rectal carcinoma is a very important method to reduce the occurrence of local complications.
ABSTRACT
Objective To assess the effect of fetal islet transplantation for the treatment of Type Ⅰ diabetes. Methods The pancreatic islets from human aborted embryos were cultured and implanted into the greater omentum and omental bursa of 26 patients with type Ⅰ diabetes. The function of transplanted islets was evaluated. Results After transplantation, the exogenous insulin requirement significantly decreased (P
