We modified our leak-proof puncture technique for the aspiration of giant ovarian cyst contents while strengthening the punctured cyst wall. After making the minilaparotomy incision, we lined a sterile gauze with the cyst surface, applied instant cyanoacrylate glue, and attached a plastic wrap over a wound retractor. The adhesion side was reinforced by the gauze and was difficult to split when aspirating the cyst contents. We then drew the cyst outside the body and performed cystectomy or oophorectomy under a narrow field of direct vision. This technique is easy and cost effective for the resection of giant ovarian cystic tumors.
