Abstract:
Park's method of submucosal hemorrhoidectomy has not gained widespread clinical use despite its minimally invasive nature. However, combining this technique with modern bipolar technology LigaSure™ offers a promising approach to surgical treatment of hemorrhoidal disease. A patient with stage III hemorrhoidal disease underwent surgery under subarachnoid anesthesia in the Lloyd Davis position. The procedure involved lifting external hemorrhoids with an Allis clamp to expose internal hemorrhoids. Using monopolar coagulation, a linear incision was made in the distal skin covering left lateral external hemorrhoids. The surgeon carefully separated varicose veins from sphincter fibers. The LigaSure™ device was then used to dissect hemorrhoidal tissue in the submucosal layer toward the hemorrhoidal artery origin. The artery was ligated 1 cm above the dentate line using bipolar technology while preserving the mucosa. Similar techniques were applied to remove right posterior and anterior hemorrhoidal tissue. The result showed three small incisions on the anoderm with complete preservation of the anal canal mucosa. The modified technique allows excision of hemorrhoidal tissue and ligation of arteries without sutures, preserving the lining of the anal canal. This approach potentially results in shorter hospital stays, less postoperative pain, and promotes rapid recovery.
