ObjectiveTo explore the effects of CO2 pneumoperitoneum and posture on circulation function for elderly patients with rectal cancer during laparoscopic operation. MethodsRetrospective analysis of clinical data of 48 elderly patients with rectal cancer was performed, and the data included the heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), cardiac output (CO), cardiac index (CI), central venous pressure (CVP), pH, partial pressure of oxygen (PaO2), and partial pressure of carbon dioxide (PaCO2) at before anesthesia (T1), after anesthesia (T2), after the establishment of CO2 pneumoperitoneum (T3), placement in trendelenburg position after operation (T4), 30 minutes after operation (T5), 60 minutes after operation (T6), 90 minutes after operation (T7), and 120 minutes after operation (T8). ResultsThe levels of HR, SBP, DBP, MAP, CO, CI, pH, PaO2, and PaCO2 at 8 time points didn't statistically differed with each other (P>0.05), but the levels of CVP at T7 and T8 time point were significantly higher than those of T1 and T2 time point (P<0.05). ConclusionsDuring laparoscopic operation period for the elderly patients with rectal cancer, the CVP will gradually increase. If the preoperative assessment and administration are done well during peri-operation period, laparoscopic operation is safe for the elderly patients with rectal cancer.
目的比較腹腔鏡膽囊切除聯合膽總管探查術（LC＋LCBDE）與內鏡下Oddi括約肌切開取石聯合腹腔鏡膽囊切除術（EST＋LC）治療膽囊結石合并肝外膽管結石的臨床療效。 方法回顧性分析45例行LC＋LCBDE及60例行EST＋LC患者的臨床資料，觀察2組在單次結石清除率、中轉手術率、手術并發癥、住院時間等指標方面的效果。 結果2組患者的基線資料相近，無手術死亡病例；2組術后并發癥發生情況的差異無統計學意義（P＞0.05）；LC＋LCBDE組單次治療成功率高于EST＋LC組，而住院時間及中轉手術率則短于或低于EST＋LC組（P＜0.05）。 結論LC＋LCBDE是治療膽囊結石合并肝外膽管結石患者安全有效的方法。
