A cumulative total of 89 h of pressure data was acquired from both sides of a left colonic anastomosis in 15 patients over a median period of 7 postoperative study days. Patients had a colonic ileus lasting 3-10 days and during this proximal and distal inactivity the intraluminal pressure remained within 6 mmHg of atmospheric pressure. After recovery of activity, pressures proximal to the anastomosis in excess of 10 mmHg occurred during less than 1 per cent of the recording time. Distal peak pressures were significantly elevated with respect to the proximal site (P less than 0.001). Two-thirds of the distal pressures recorded were between 10 and 20 mmHg and 98 per cent were less than 50 mmHg; the peak distal pressure was 90 mmHg. Four patients had distal repetitive tonic contractions creating a pressure difference across the anastomosis with a mean of 20 mmHg and a peak of 45 mmHg. Each contraction persisted for 15-20 min. Intraluminal pressures are unlikely to play a role in anastomotic dehiscence.
在术后中位研究期7天内,从15例患者左结肠吻合口两侧累计采集了89小时的压力数据。患者结肠麻痹持续3 - 10天,在此近端和远端无活动期间,腔内压力保持在大气压力的6 mmHg范围内。活动恢复后,吻合口近端压力超过10 mmHg的情况在记录时间中占比不到1%。远端峰值压力相对于近端部位显著升高(P小于0.001)。记录的远端压力中有三分之二在10至20 mmHg之间,98%小于50 mmHg;远端峰值压力为90 mmHg。4例患者出现远端重复性强直性收缩,在吻合口处产生平均20 mmHg、峰值45 mmHg的压力差。每次收缩持续15 - 20分钟。腔内压力不太可能在吻合口裂开中起作用。
