A questionnaire was used to study the choice and use of gastric function tests by members of the British Society of Gastroenterology.Pentagastrin has largely replaced older drugs as the stimulant of choice for evoking maximal acid secretion. Insulin tests are being used in situations where they are unlikely to provide useful clinical information. Fewer physicians than surgeons measure gastric secretion, and they use tests less often. The reluctance of physicians to test patients with uninvestigated dyspepsia or gastric ulcer seems justified, but in patients having dyspepsia with negative x-ray films, or after gastrectomy or vagotomy, the greater investigative keenness of surgeons seems commendable. Only half the surgeons ever try to assess the completeness of their vagotomies, and in only one-third of this half is it their usual practice. Criticism is made of the practice of routine measurement of acid in patients with duodenal ulcer, and of the use of acid measurements to decide whether a patient should have surgery or which type of operation should be performed.
采用问卷调查的方式，对英国胃肠病学会成员选择和使用胃功能检查的情况进行了研究。五肽胃泌素已在很大程度上取代了旧药，成为激发最大胃酸分泌的首选刺激剂。胰岛素试验正在一些不太可能提供有用临床信息的情况下使用。测量胃分泌功能的内科医生比外科医生少，而且他们使用检查的频率也较低。内科医生不愿对未经调查的消化不良或胃溃疡患者进行检查似乎有其道理，但对于X线片检查阴性的消化不良患者，或胃切除术后或迷走神经切断术后的患者，外科医生更积极的检查热情似乎值得称赞。只有一半的外科医生曾试图评估他们所做迷走神经切断术的彻底性，而且在这一半医生中，只有三分之一的人将此作为常规做法。文中对十二指肠溃疡患者常规测量胃酸的做法，以及利用胃酸测量结果来决定患者是否应该接受手术或应进行何种手术的做法提出了批评。
