The objective of this study was to determine whether the size of the pyloric mass is one of the factors in the surgeon's ability to palpate the pyloric "olive".
The ultrasonographic images and medical records of 60 infants with surgically confirmed hypertrophic pyloric stenosis (HPS) were reviewed. The pyloric diameter (PD) and pyloric length (PL) were measured and the pyloric volume (PV) was calculated using the equation PV = 1/4pi x (PD)2 x PL. Based on the pediatric surgeon's physical examination the infants were divided into two groups: those with and those without palpable pyloric masses.
Infants with a palpable pyloric mass had an average pyloric volume of 3.33 +/- 1.76 mm3, which was statistically larger than those whose hypertrophied pylorus could not be palpated (average volume 2.59 +/- 2.07 mm3, P < 0.01). There was no statistically significant age difference between the two groups.
Clinical skill of the examiner and other clinical aspects (patient cooperation, etc.) determine palpability of the pylorus in HPS. The size of the hypertrophied pylorus is also an important factor affecting the clinician's ability to palpate the pyloric mass.
本研究的目的是确定幽门肿块的大小是否是影响外科医生触诊幽门“橄榄样肿物”能力的因素之一。
回顾了60例经手术证实为肥厚性幽门狭窄（HPS）婴儿的超声图像和病历。测量幽门直径（PD）和幽门长度（PL），并使用公式PV = 1/4π×(PD)²×PL计算幽门体积（PV）。根据儿科外科医生的体格检查，将婴儿分为两组：可触及幽门肿块的婴儿和不可触及幽门肿块的婴儿。
可触及幽门肿块的婴儿幽门平均体积为3.33±1.76 mm³，在统计学上大于肥厚性幽门不可触及的婴儿（平均体积2.59±2.07 mm³，P < 0.01）。两组之间在年龄上无统计学显著差异。
检查者的临床技能和其他临床因素（患者配合等）决定了HPS中幽门的可触知性。肥厚性幽门的大小也是影响临床医生触诊幽门肿块能力的一个重要因素。
