目的 观察左侧结肠癌伴急性肠梗阻一期手术的疗效，探讨理想的手术治疗方法。方法 回顾性分析四川大学华西医院2007年1月至2009年11月期间收治的46例左侧结肠癌伴急性肠梗阻患者一期手术切除吻合的临床资料。结果 46例均未实施术中结肠灌洗，而行彻底的无污染肠减压法。其中行根治性切除一期吻合35例，姑息性切除一期吻合11例。术后发生吻合口漏3例，切口感染6例，肺部感染2例，盆腔积液1例，均经非手术方法治愈。全组手术无死亡病例。结论 左侧结肠癌伴急性肠梗阻一期切除吻合，用彻底的无污染肠减压法替代结肠灌洗是安全、可行的。
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。
Objective To compare the clinical effects of one-stage anastomosis on patients with middle and lower rectum carcinoma and intestinal obstruction and the ones without intestinal obstruction, and to evaluate the safety and feasibility of patients with middle and lower rectum carcinoma and intestinal obstruction undergoing one-stage anastomosis. Methods The data of patients diagnosed definitely by pathology as middle and lower rectum carcinoma underwent one-stage anastomosis in West China Hospital of Sichuan University between January 2007 and December 2008 was retrospectively analyzed. The clinical effects were compared between intestinal obstruction group and non-intestinal obstruction group. Results During this period, 525 patients were included into intestinal obstruction group (n=87) and non-intestinal obstruction group (n=438). Among the patients included, there were 307 males and 218 females. Ages were from 25 to 85 years, and the average age was 60 years old. According to tumor histology, there were 487 cases of adenocarcinoma, 29 of mucinous adenocarcinoma and 9 of other types. According to the degree of tumor differentiation, there were 140 cases of low differentiation, 372 of middle differentiation and 13 of high differentiation. According to TNM stage, there were 4 cases of stage 0, 93 of stageⅠ, 189 of stage Ⅱ, 202 of stage Ⅲ and 37 of stage Ⅳ. Constituent ratio of gender, distributions of distances from tumor to anus, TNM stages and differentiation degrees of tumor were significantly different between intestinal obstruction group and non-intestinal obstruction group (Plt;0.05); and there was no statistical difference in the age, pathological types， significant internal medical complications and operative types between the two groups (Pgt;0.05). There was no statistical diffe rence in operative duration and intraoperative blood loss between the two groups (Pgt;0.05). There was no statistical difference in postoperative time of first defecation, first out-of-bed activity and first oral feeding, and postoperative hospital stay between the two groups (Pgt;0.05); while time of first aerofluxus was earlier in intestinal obstruction group than that in non-intestinal obstruction group (Plt;0.05). There was no statistical significance in the disease incidence of postoperative complications between the two groups (Pgt;0.05). Conclusions Comparing with patients with non-intestinal obstruction, there is no significant evidence shows that one-stage anastomosis will affect the rehabilitation and increase the risk of complications in patients with middle and lower rectum carcinoma and intestinal obstruction. It is considered that it would be safe and feasible for patients with middle and lower rectum carcinoma and intestinal obstruction to have one-stage anastomosis; however, it is necessary for us to have more researches to evaluate the long-term clinical effect.
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.
Objective To investigate the surgical techniques for management of left colon carcinoma obstruction. MethodsThe techniques used in left colon carcinoma obstruction and the corresponding efficiencies reported in foreign literatures were reviewed. ResultsThe surgical techniques for management of left colon carcinoma obstruction involve palliative operation, staged operation and onestage operation. These methods had their own virtues as well as shortages. But on all accounts, onestage operation was favorable for both the patients and docters. ConclusionDifferent methods for management of left colon carcinoma obstruction have different adaptation index, first you must ensure safety, then you should try your best to do onestage operation.
