The postoperative transit times of radioopaque markers through the gastrointestinal tract where measured in 6 patients after gastric surgery, in 13 patients after cholecystectomy, in 10 patients after appendicectomy and in 7 other patients who underwent general anesthesia without laparotomy. After ingestion of 20 markers, overall and segmental transit times were calculated according to their distribution on serial plain films of the abdomen taken 6 and 24 h after the operation, and every 24 h thereafter until complete evacuation of the markers. Overall transit times of the 3 groups of patients with laparotomy (171, 130 and 113 h respectively) were greater than overall transit times of patients without laparotomy (25 h). Overall transit times of patients with gastric operations were greater than overall transit times of patients with cholecystectomy (p less than 0.05) or appendicectomy (p less than 0.01). The increase in overall transit time was mainly due to an increased gastric transit time in patients after gastric surgery and an increased transit time through the right colon in patients who underwent cholecystectomy and appendicectomy. Once markers began to be defecated, their disappearance rate was the same in the 4 groups of patients. These results show that an increased overall transit time may be the consequence either of an increased transit time through the stomach or through the right colon, depending on the type of operation. As well, when digestive propulsive activity returns, it is de novo normal.
对6例胃手术后患者、13例胆囊切除术后患者、10例阑尾切除术后患者以及7例接受非剖腹全身麻醉的其他患者，测量不透X线标志物在胃肠道的术后通过时间。摄入20个标志物后，根据术后6小时和24小时以及此后每24小时拍摄的腹部连续平片上标志物的分布情况，计算总体和分段通过时间，直至标志物完全排出。三组接受剖腹手术患者的总体通过时间（分别为171、130和113小时）长于未接受剖腹手术患者的总体通过时间（25小时）。胃手术患者的总体通过时间长于胆囊切除术患者（p<0.05）或阑尾切除术患者（p<0.01）。总体通过时间增加主要是由于胃手术后患者胃通过时间增加，以及胆囊切除术和阑尾切除术患者右结肠通过时间增加。一旦标志物开始排出，四组患者中其消失率相同。这些结果表明，总体通过时间增加可能是胃或右结肠通过时间增加的结果，具体取决于手术类型。同样，当消化推进活动恢复时，其是重新恢复正常的。
