Robotic Myotomy and Partial Fundoplication for Achalasia
Published on: August 11, 2023
[Functional changes in the cardioesophageal region following laparoscopic fundoplication]
Unlabelled:
Functional changes of antireflux mechanisms after laparoscopic fundpolication.
Aim:
To examine manometry and pH-study in evaluation of the changes in measurable features of antireflux mechanisms after fundoplication for gastro-oesophageal reflux disease.
Methods:
Laparoscopic Nissen-Rossetti fundoplications with hiatorhaphy were performed in patients with gastroesophageal reflux disease. Preoperative and postoperative manometry and pH-study were compared in set of twenty satisfied orjerated without any complaints after surgery who agreed with preoperative and postoperative examinations.
Results:
Higher length of lower esophageal sphincter following antireflux fundoplication (P = 0.0003), increased tone of lower esophageal sphincter with antireflux fundoplication (P = 0.0001) and lower value of pH-study after fundoplication (P = 0.0001) were observed.
Conclusion:
Postoperative manometry and pH-study effectively evaluated gastro-oesophageal reflux changes following fundoplication for gastro-oesophageal reflux disease.
