In this letter-to-editor, we hypothesize that there is a link between hemorrhoidal disease and hiatal hernia. We underline common risk factors for both and present a cross-sectional patient data. Therefore, we emphasize the necessity of new studies to clarify this coincidence. Clinical benefit of establishment of this link is to delay or prevent development of hiatal hernia as a result of appropriate preventive measures. Accordingly, postoperative period of hiatal hernia operations may also be relieved or recurrence risk may also be decreased with this precautions.

During routine dissections on a 65-year-old male cadaver, we encountered double piriformis, double gemelli superior and inferior, double quadratus femoris muscles in the left gluteal region. The sciatic nerve passed between the lower piriformis and the upper superior gemelli muscles infrapiriform foramen as usual. No other variation was found in the region. This rare variation may be of importance in the radiology and surgery of this region.
