Sammanfattning

How best to surgically treat GERD is an unresolved issue. To increase our insights into the fundoplication procedures, functional consequences for the gastroesophageal junction of an anterior or a posterior partial fundoplication were studied by manometry. Patients were randomly selected from a larger study in a randomised comparison between posterior and anterior partial fundoplications. The manometric studies were done 12 months after respective procedures in 24 patients. The motor characteristics of the esophagus and lower esophageal sphincter (LES) function were determined by use of sleeve catheter manometry. The manometric characteristics of the esophageal body were similar in the study groups except for the ramp pressure. This was significantly higher in patients with posterior partial fundoplications. The posterior group had significantly longer total length (P < 0.02) as well as longer intra-abdominal portions (P = 0.07) of the LES while the basal tone, albeit numerically higher, did not reach statistical significance. Water-swallow induced LES relaxations reached lower nadir values in the anterior group (1.7 vs 2.7 mmHg). Gas distension triggered few transient LES relaxations in both study groups while common cavities were more frequently observed in those having an anterior partial wrap (P < 0.01). A posterior partial fundoplication is followed by manometric characteristics suggesting a well functioning antireflux barrier with some obstruction to bolus passage as well as restricted venting of air from the stomach. The manometric mechanisms behind the inferior reflux control achieved by a Watson type of anterior partial wrap has now been further elucidated.
