Obesity poses no barrier to effective antireflux surgery outcomes.

In a study of 2,388 patients, those with BMI ≥35 had similar symptom improvement (GERD-HRQL scores: 10.7 vs. 10.1) and satisfaction rates (81.6% vs. 83.3%) post-operation compared to non-obese patients.
Five-year anatomic integrity (75.8% vs. 78.2%) and revision rates (4.5% vs. 5.3%) were also comparable.
However, obese patients had lower rates of pH normalization in the magnetic sphincter augmentation group (48.1% vs. 71.0%).

These findings support considering obese patients for antireflux surgery without BMI being the sole factor in candidate selection.

Uniportal esophagectomy linked to fewer pneumonias

In nine comparative studies of minimally invasive esophagectomy for esophageal cancer, uniportal VATS was associated with less pneumonia and a shorter stay than multiportal VATS—but the evidence is not strong enough to establish a preferred approach.
