腹腔镜胆囊切除术后气腹存留时限的X线观察

An X-ray observation about the duration of pneumoperitoneum following laparoscopic cholecystectomy

目的 观察腹腔镜胆囊切除术后气腹存留时限。 方法 对我院 2 0 0 2年 4月～ 2 0 0 2年 12月 6 9例腹腔镜胆囊切除术 (laparoscopiccholecystectomy ,LC)术后进行连续胸部X线平片观察膈下游离气体。 结果 LC术后气腹存留时限为(1 8± 1 1)d ,6d内完全吸收。lg气腹存留时限 与术后 2 4h膈下残气量呈正相关 (r=0 6 16 ,P =0 0 0 0 ) ,与气腹时间呈负相关(r=- 0 2 2 8,P =0 0 14 ) ,与年龄、体重、身高、手术时间及所用气体量无相关性。 结论 术毕尽量将腹腔内CO2 气体排净可缩短术后气腹吸收时间。

Objective To observe the length of duration of free gas presence in abdomen after laparoscopic cholecystectomy (LC). Methods A Series of chest X-ray examinations following LC in 69 patients in this hospital from April 2002 to December 2002 were taken to review the condition of subphrenic free gas. Results Gas was detected on (1.8±1.1) days following LC and was completely absorbed within 6 days after LC. The logarithm of the length of duration of pneumoperitoneum had a parallel relationship with the subphrenic residual gas volume within 24 postoperative hours ( r =0.616, P =0.000), bore a negative relationship with the pneumoperitoneum time ( r =-0.228, P =0.014), and was not correlated with age, body weight, height, operation time and consumption of CO 2. Conclusions Clearing intraabdominal CO 2 gas away so far as possible can shorten the length of duration of gas presence in abdomen.
