目的评估PK刀在腹腔镜阑尾切除（LA）中的应用价值。方法回顾性分析广西桂东人民医院2009年6月至2010年6月期间68例行LA患者的临床资料，其中PK刀组34例，高频电凝钩组34例，比较2组患者的手术时间、术中出血量、术后肠道功能恢复时间及住院时间。结果所有手术均获成功，无中转开腹及术后大出血等并发症发生，PK刀组较高频电凝钩组的手术时间明显缩短(Plt;0.05)、术中出血量明显减少(Plt;0.05)及术后肠道功能恢复时间更快(Plt;0.05)； 住院时间2组间差异无统计学意义(Pgt;0.05)。结论PK刀具有凝固均匀、完全、热损伤少、止血效果好、操作简单等优点，可选择性地应用于LA。
ObjectiveTo explore the effect of partial splenic embolization on splenectomy plus devascularization of esophageal and gastric vein. MethodsTwenty three cirrhosis patients with portal hypertension combined the hypersplenism (partial splenic embolization group), who received partial splenic embolization in our hospital from June 2010 to June 2015, as well as 30 cirrhosis patients with portal hypertension combined the hypersplenism without undergoing partial splenic embolization in the same period (non-partial splenic embolization group), were collected retrospectively. All patients underwent splenectomy plus devascularization of esophageal and gastric vein. Comparison of operation time, intraoperative blood loss, intraoperative blood transfusion volume, postoperative total flow of abdominal drainage tube, postoperative gastrointestinal function recovery time, hospital stay, and the incidence of complication was performed. ResultsThe operation time[(3.56±0.70) h vs. (1.78±0.28) h], intraoperative blood loss (900 mL vs. 250 mL), intraoperative blood transfusion volume (800 mL vs. 200 mL), postoperative total flow of abdominal drainage tube (450 mL vs. 150 mL), postoperative gastrointestinal function recovery time[(43.38±18.68) h vs. (27.60±12.39) h], hospital stay (12 d vs. 7 d), and incidence of incision infection[34.8% (8/23) vs. 10.0% (3/30)] of partial splenic embolization group were all higher or longer than those corresponding indexes of non-partial splenic embolization group (P < 0.05). All patients of 2 groups were followed up by telephone visit for 6-58 months, and the median was 28-month. There was no recurrence of gastrointestinal hemorrhage during the follow-up period. ConclusionsSplenectomy is more difficult, and maybe has more intraoperative blood loss and complications for cirrhosis patients with portal hypertension combined the hypersplenism, who received partial splenic embolization ever. For these patents, the recovery time is longer. We should make choice of partial splenic embolization or splenectomy directly according to the patients' situation, to implement individualized treatment, so we can make the biggest benefit for patients.
