ABSTRACT
Hypertrophic pyloric stenosis [HPS] is a common cause of gastric outlet obstruction [GOO] in infants. Prolonged GOO is believed to result in acid and electrolyte disturbances, gastric atony, and delayed postoperative recovery. We studied the impact of prolonged vomiting as an indicator of GOO symptoms on the post-operative outcomes in HPS. A retrospective chart review of all patients who underwent pyloromyotomy at a tertiary care center between February 1997 and February 2009. The duration of pre-operative vomiting was correlated with presenting electrolytes and acid-base balances, postoperative time to full feed, postoperative morbidity and duration of hospitalization. Forty-seven patients were identified. At presentation, the median [range] for duration of symptoms was 14 [3-60] days, and surgeries were performed at 2 [0-6] days after admission. Apart from one case of postoperative wound infection, all patients had an unremarkable recovery. The unusually prolonged duration of vomiting in our cohort did not correlate with the mean [SD] preoperative chloride level of 93.9 [8.8] mEq/L, mean [SD] pH level of 7.5 [0.9], mean postoperative time to full feeding of 31 [15.1] hours, or mean duration of hospitalization of 5.1 [2.2] days. Duration of vomiting in HPS at presentation does not seem to have a significant impact on the postoperative outcomes

La heterotopia pancreática (HP) es una lesión relativamente infrecuente, observada con mayor frecuencia en el estómago. En la mayoría de los casos laHP es asintomática, pero puede ocasionalmente acompañarse de dispepsia y hemorragia gastrointestinal superior. Se describe el caso de un hombre de 40 años de edad con obstrucción del vaciamiento gástrico, secundario a HP en el antro.
Heterotopic pancreas (HP) is a relatively infrequent lesion most often found in the stomach. In the majority of cases, HP does not cause symptoms, but it can occasionally present as dyspepsia and upper gastrointestinal bleeding. This report describes the case of a 40-year-old man with gastric outlet obstruction resulting from HP in gastric antrum.
