hypertrophic pyloric stenosis, pyloromyotomy, remote consequencesAbstract
Hypertrophic pylorostenosis is one of the most frequent causes of vomiting in newborns requiring surgical intervention. While the intraoperative complications and immediate results of pyloromyotomy are widely reported in the literature, the remote consequences of this intervention, especially depending on the method of correction, are not well understood and contain contradictory results.
Purpose - to study the remote consequences of pyloromyotomy depending on the method of surgical correction - open (OMPT) or laparoscopic pyloromyotomy (LMPT).
Materials and methods. The primary assessment of long-term outcomes was performed by analysing the answers to the questions of the Diagnostic Questionnaire for Paediatric Functional Gastrointestinal Disorders, which was sent to 246 patients and their parents; responses were received from 169 (68.7%) respondents, who were included in the study. Re-hospitalisation was required in 57 (33.7%) children who underwent X-ray examination, fibrogastroscopy and ultrasonography.
Statistical processing of the study results was performed using the software StatPlus: mac, AnalystSoft Inc. (version v8).
Results. The average age of patients involved in the study was 8.5±0.3 years (range of fluctuations - from 2 to 18 years old). Among the respondents, 132 (78.1%) children underwent OPMT, and 37 (21.9%) children underwent LPMT. No complaints were expressed by 102 (60.4%) children, including 81 (61.4%) children after OPMT and 21 (56.8%) after LPMT (p=0.6152).
The main complaint in children after pyloromyotomy, which required re-hospitalisation, was chronic abdominal pain, as indicated by 38 (22.5%) of the respondents. There was no correlation between the occurrence of chronic abdominal pain and the age at which hypertrophic pylorostenosis was diagnosed (R=0.183, p=0.2588), the duration of the disease (R=0.079, p=0.6275) and the child's body weight at the time of the intervention (R=0.048, p=0.768). Functional disorders of the digestive tract were diagnosed in 15 (8.9%) children. In 24 (14.2%) children, a slowdown in barium passage through the intestine was detected, which, in combination with periodic pain, indicated chronic adhesive disease.
Fibrogastroscopy revealed duodenogastric reflux in 18 (10.7%) children, which in 5 (2.96%) patients was combined with pylorus insufficiency and in 12 (7.1%) with gastritis, and in 17 (10.1%) children gastroesophageal reflux was diagnosed.
Conclusions. Thus, in the long term after pyloromyotomy, 33.7% of children required re-hospitalisation due to various pathologies of the gastrointestinal tract. Duodenogastric and gastroesophageal reflux and chronic adhesive disease were most often detected in the long term after pyloromyotomy, and the frequency of their occurrence did not depend on the method of surgical intervention.
The research was carried out in accordance with the principles of the Helsinki Declaration. The study protocol was approved by the Local Ethics Committee of the institution mentioned in the paper. The informed consent of the patient was obtained for conducting the studies.
No conflict of interests was declared by the authors.
