【Abstract】Objective To explore the relation between the expression of telomerase and DNA ploidy with biliarypancreatic system cancer, so as to find a better way to diagnose and distinguish jaundice between malignance and benign disease.Methods Endoscopic retrograde cholangiopancreatography (ERCP) were performed before operation in patients with obstructive jaundice. The bile and pancreatice juice were collected before ERCP. Biopsy specimens from part of patients were obtained during ERCP. All cancer specimens were possessed once again during operation and were assessed by the activity of telomerase and DNA ploidy. Results ① Telomerase positive rate 〔87.50%(56/64)〕 of tissue specimens in malignant obstructive jaundice were higher than that in benign obstructive jaundice 〔3.33%(2/60)〕，P=0.000. ② Telomerase positive rate〔71.88%(46/64)〕of Bile and pancreatice juice in malignant obstructive jaundice were higher than that in benign obstructive jaundice 〔3.33%(2/60)〕， P=0.000, tissue specimens obtained by endoscopy with malignant obstructive jaundice had detectable telomerase activity, positive rate was 83.33%（20/24）. ③ The rate of DNA heteroploid with malignant obstructive jaundice was 62.50%（40/64）, that of diploid can be seen in all patients with benign obstructive jaundice, the difference was statistically significant (P=0.000). ④ The rate of telomerase positive and DNA heteroploid in high differentiation tumor were significantly lower than in middlelow differentiation tumor （P=0.028，P=0.001）.Conclusion Applying the duodenoscope we collected the bile and pancreatic fluid before operation and obtain biopsy specimens whose telomerase activity and DNA ploid were detected. This is simple, safe, quick method which can identify the malignant and benign obstructive jaundice.

目的 探讨腹腔镜粘连松解术治疗粘连性肠梗阻的应用价值。方法 对我院2005年7月至2011年9月期间采用腹腔镜进行肠粘连松解术的27例患者的临床资料进行回顾性分析。结果 27例患者中除2例因术中探查发现小肠坏死而中转开腹行肠切除外，其余25例均手术成功，手术时间（65±15） min （40～115min）。27例均获随访，随访时间（14±6）个月（8个月～2年），1例患者于术后1个月时有阵发性腹痛，经保守治疗缓解，其余病例均无腹胀、腹痛等症状发生。结论 腹腔镜粘连松解术治疗粘连性肠梗阻具有创伤小、恢复快的优点，是较理想的治疗术后肠粘连的手段。
目的 探讨预防左半结肠癌伴梗阻Ⅰ期切除吻合术后吻合口漏发生的新方法。方法 将215例左半结肠癌伴梗阻接受术中结肠灌洗和Ⅰ期切除吻合等处理的患者分为两组。双管引流组术中经肛门放置肠腔内双管引流；扩肛组术中不放置肠腔内引流管，术后定时扩肛。对两组患者术后腹腔脓肿和吻合口漏发生率进行对比分析。结果 腹腔脓肿和吻合口漏发生率双管引流组分别为3.1%(4/130)和3.8%(5/130)，扩肛组分别为10.6%(9/85)和12.9%(11/85)，两组腹腔脓肿和吻合口漏发生率之差异均有显著性意义(P＜0.05)。结论 肠腔内双管引流法具有预防性结肠“内造瘘”、减压减张、冲洗洁净和持续性扩肛作用，能有效地预防和减少左半结肠癌伴梗阻I期切除吻合术后吻合口漏的发生。
目的 探讨股疝的发病特点、诊断注意事项、误诊分析及治疗方法。方法 回顾性分析我院1993年1月至2008年1月期间38例股疝患者的临床资料。结果 38例患者年龄均在40岁以上，全部行手术治疗，1例术后3 d因心肌梗死死亡，1例因肠坏死、多器官功能衰竭死亡，余36例均痊愈出院，术后平均随访72个月无复发。结论 股疝容易嵌顿，中老年患者多见,临床上易被误诊，应尽早确诊，及时手术。
【Abstract】Objective To study the expression of serum soluble interleukin-2 receptor (sIL-2R) level in perioperative period of patients with obstructive jaundice and its clinical significance. Methods Serum sIL-2R was measured during perioperative period in 30 patients with obstructive jaundice by using a sandwich enzyme linked immunosorbent assay (ELISA). Results The preoperative serum sIL-2R level in patients with obstructive jaundice was increased obviously. The expression of serum sIL-2R level in them was correlated with the degree and duration of obstructive jaundice and nutritional status respectively (r=0.734, P＜0.01; r=0.646, P＜0.01; r=0.594, P＜0.05). The serum sIL-2R in the patients with malignant obstructive jaundice was significantly higher than that with benign obstructive jaundice (P＜0.05). Among the patients with malignant obstructive jaundice, the serum sIL-2R level in the patients with metastasis was higher than in those without metastasis (P＜0.05). The immunologic function underwent a process from temporary suppression to gradual recovery during perioperative period. On the 21th day after operation the sIL-2R was recovered to normal level in patients with benign obstructive jaundice while it only recovered to preoperative level in patients with malignant obstructive. Conclusion Depressed immunity is observed in patients with obstructive jaundice. The abnormal expression of sIL-2R is related to the type, degree and duration of obstructive jaundice and the nutritional status and metastasis. The result that preoperative sIL-2R might be used to evaluate the state of immunity, clinical condition, and treatment and prognosis of patients with obstructive jaundice.
Objective To compare the therapeutic effect of percutaneous transhepatic cholangial drainage (PTCD) and operation drainage for the patients with inoperable malignant obstructive jaundice. Methods A total of 131 patients with inoperable malignant obstructive jaundice were treated in this hospital, in which 102 patients had PTCD by placement of metallic stent and (or) plastic tubes to remove obstruction of bile duct (interventional treatment group). Simultaneously 29 patients were selected for operation by intraexternal drainage (operation drainage group). The patients were followed up for comparison of the serum level of total bilirubin, postoperative complications, average length of hospitalization and average cost between the two groups. Results PTCD was successfully performed in all the patients of the interventional treatment group. There were no significant differences of 50% decrease period of average total bilirubin level or postoperative complications between the two groups (Pgt;0.05). The average length of hospitalization and average cost of interventional treatment group were less than those of operation drainage group (Plt;0.05). Conclusions Compare with operation drainage, interventional treatment can reduce average length of hospitalization and average cost, without increase of postoperative complications, which is a main chance of treatment for malignant obstructive jaundice.
Different types of bowel obstruction,including strangulated loop,mesenteric venous occlusions,mesenteric arterial occlusions and simple obstruction, were induced in rabbits.After induction of occlusion, imaging agent of 99mTc-pyrophosphate was injected intravenously.Thirty minutes later,abdominal plain image was successively taken with a single photon emission computed tomography (SPECT).At the same time,the uptake ratio of region of interest was determined.The results revealed that animals in strangulated loop group and mesenteric venous occlusion group had high radioactive concentration in the area of ischemic bowel. Uptake ratio of region of interest of imaging area in the two experimental group was higher than that in simple obstruction and control group.Whereas the mesenteric arterial occlusion group did not appearantly present the changes mentioned above.These showed that there was an accumulation of agent in strangulated ischemic bowel segment in strangulated loop group and mesenteric venous occlusion group.All results suggest that radionuclide visualization with SPECT could be a valuable method for early diagnosis of acute intestinal strangulation of strangulated loop type and mesenteric venous occlusion type.
