An analysis of the factors which may predispose towards postoperative vomiting after pyloromyotomy for hypertrophic pyloric stenosis was carried out in 72 infants at this hospital. 26 (36%) infants experienced moderate to severe postoperative vomiting of sufficient intensity to cause the postoperative feeding regimen to be modified or interrupted. Only two parameters were found to be of statistical significance. These were the state of the oesophageal mucous membrane on endoscopical examination and the presence of haematemesis in the preoperative period. No evidence for a gastric mucosal lesion could be found. An advanced oesophageal mucosal lesion was found in 30% of patients, and this was the source of the haemorrhage in all 11 in whom haematemesis was noted postoperatively. The stay in hospital was prolonged (8 days) in those infants with troublesome vomiting postoperatively compared with those with lesser problems (3 days).
本院对72例肥厚性幽门狭窄行幽门肌切开术后可能导致术后呕吐的因素进行了分析。26例（36%）婴儿出现中度至重度术后呕吐，严重程度足以导致术后喂养方案改变或中断。仅发现两个参数具有统计学意义。这些参数是内镜检查时食管黏膜的状态以及术前是否存在呕血。未发现胃黏膜病变的证据。30%的患者发现有进展期食管黏膜病变，这是所有11例术后出现呕血患者的出血来源。与呕吐问题较轻的婴儿（3天）相比，术后呕吐严重的婴儿住院时间延长（8天）。
