Objective To discuss the technical keypoints of the second-phase diaplasis treatment after Hartmann operation. Methods Twenty-one cases of the second-phase diaplasis operation of Hartmann operation in this hospital from January 2003 to December 2007 were analysed retrospectively. Results In this group, stapler technique was used in 15 cases, anastomotic ring was used in 3 cases, and one-layer suture was used in 3 cases. The time of these operations was between 118 min and 240 min (mean 164 min). Neither stomal leak nor stomal stenosis occurred, acute ileus occurred in 2 cases, and both recovered after the treatments of gastrointestinal decompression, inhibition of secretion digestive juice and reoperation. Acute retension of urine occurred in 1 case after urine catheter removed. The symptoms disappeared after excises of bladder function. These cases were followed up for 3-36 months (mean 20 months). All the patients recovered to normal function of defecation. Conclusion The technical keypoints of the second-phase diaplasis treatment after Hartmann operation are how to find and liberate the end of the distal colon. It will affect the prognosis and the occurrence of complications after this operation.
【摘要】目的 探讨腹腔镜辅助下小肠切除术的治疗价值。 方法 回顾性分析我院2001年7月至2004年9月期间实施腹腔镜辅助下小肠切除术10例患者的临床资料。 结果 除1例中转开腹外，余 9例均实施腹腔镜辅助下小肠切除。平均手术时间(70.2±18.3) min （60～120 min），术中平均出血量(30.3±12.6) ml （15～50 ml），平均住院时间(6.5±1.6) d （5～8 d）。所有患者均在术后24 h开始下床活动，48 h内恢复胃肠功能。术后无一例使用止痛剂。全组手术无病灶遗漏,无并发症和手术死亡发生。 结论 腹腔镜辅助下小肠切除术安全、经济并具有良好的治疗效果。
目的 探讨十二指肠球后溃疡穿孔临床上正确的围手术期处理办法。方法回顾性分析我院1998年5月至2004年11月6例十二指肠球后溃疡穿孔的临床症状、穿孔部位、手术方式、治疗结果和随访情况。结果6例患者均为溃疡穿孔，分别行急诊手术，术后1例死亡，1例转院，4例完全治愈。结论术中根据患者条件选择合理的手术方式，重视术后引流，早期肠内营养是改善患者预后的关键。
Objective To investigate the impact of conversion to open in laparoscopic rectal cancer radical resection (LRR) on postoperative recovery. Methods The data from Feb. 2003 to Feb. 2007 of 176 cases who were given LRR and 32 cases receiving conversion in LRR (CRR) were analyzed retrospectively, and were compared about operation time, hospitalization time, hospitalization expenses, intraoperative blood loss, recovery time of bowel movement and postoperative complications with 59 cases of open rectal cancer radical resection (ORR). Results There were no differences among LRR, CRR and ORR about operation time, hospitalization time, intraoperative blood loss and recovery time of bowel movement (Pgt;0.05). The hospitalization expenses of LRR and CRR were higher than that of ORR (P=0.001, P=0.001), there was no difference between CRR and LRR (P=0.843). But the postoperative complications rate of ORR was higher than those of LRR and CRR （P=0.023,P=0.004）. Conclusion Compared with ORR, LRR has relatively conversion rate, and then increases the hospitalization expenses.
A new cool-tip radiofrequency (RF) ablation therapeutic instrument based on impedance control algorithm is introduced in this paper. The equipment is composed of hardware system and software system. The RF power output and real time data acquisition are completed by the hardware system, while the software is used mainly to finish the control of the ablation range, the core of which is impedance control algorithm, and it also used to complete the display of the real time data in the course of the experiment. The impedance algorithm has solved the problem of impedance increased rapidly during the RF ablation, which has also expanded the scope of ablation. The pig liver experiments showed that the impedance control algorithm had strong adaptability. It also obtained a result of ablation range up to 3.5~4.5 cm single needle. It has the high clinical practical value of one-time inactivation of 3~5 cm tumor.
Objective To analyze the risk factors inducing tumor cells exfoliating during radical resection of rectal cancer. Methods Sixty patients who were diagnosed as rectal cancer from May 2006 to November 2007 and given radical operations were assigned prospectively in this study. Before cutting the rectal stump below the tumor, saline was instilled into rectum to irrigate the stump. Collected irrigating fluids were sent to pathology laboratory, and the exfoliated malignant cells were tested by HE （haematoxylin and eosin） dyeing and common smear technique. The results of examines were collected and statistical analysis, including a Logistic regression model, was performed. Results Exfoliated malignant cells were found in 27 samples. By univariate analysis, the statistically significant factors defining a high risk of exfoliating were age, tumor size, TNM stage, operation time and operation method (Plt;0.05). Only TNM stage， operation time and operation method were confirmed by Logistic regression analysis to independently result in a statistically significant increased risk of exfoliating. Conclusion Irrigating the rectal stump before cutting down the tumor is essential to avoid local recurrence. The effects of TNM stage, tumor size and operation time are important. Although the laparoscopic surgery is more predominant than conventional surgery for non-neoplasma technology, irrigating is an important process.
