Purpose: The aim of this study was to evaluate the effectiveness of local anesthesia compared to spinal anesthesia and the usefulness of pentothal induction before infiltration of a local anesthetic agent. Methods: A concurrent non-randomized prospective study was conducted on 52 patients who underwent a hemorrhoidectomy. For the spinal anesthesia (SA) group (n=29), 0.5% heavy bupivacaine (MarcaineⓇ), 5 mg (1 ml), was used, and for the local anesthesia (LA) group (n=23), pentothal, 3.3 mg/kg, was administrated intravenously prior to infiltration of a mixture of local anesthetics (2% lidocaine, 14 ml, with 0.5% bupivacaine, 7 ml). Results: There were no differences between the two groups in terms of operating time, postoperative pain, headache, urinary difficulty, nausea or vomiting, pain-free interval after operation, analgesic requirements, and patient's or surgeon's satisfaction. Postoperative ambulation was earlier in the LA group than in the SA group. Conclusions: Local anesthesia after pentothal induction can be used effectively for a hemorrhoidectomy and may be a safe alternative to spinal anesthesia.

Purpose: Hemorrhoidal tissues are normal anatomic structures present in every individual, and they act as cushions and are anchored to the internal anal sphincter by a connective tissue system. When the anchoring connective tissues undergo bears degenerative changes, the hemorrhoids not only bulge but also descend into the lumen of the anal canal. The veins also become distended. The previous hemorrhoidectomy methods (excision and ligation methods) tend to remove excessive amounts of hemorrhoidal tissues, possibly causing incontinence or stenosis. This study introduces a modified hemorrhoidectomy method. Methods: A retrospective study was done with 650 patients (358 males, 292 females) who underwent hemorroidectomies from Jan. 1997 to Jan. 2000. Under saddle-block anesthesia, the patient was placed in a prone jack-knife position. After narrow incisions on the mucosa of the selected pile, a bilateral submucosal dissection was performed. The pedicle was ligated by transfixing sutures 2 or 3 times with 2-0 chromic catgut to lift up the mucosa. Results: The mean operation time per hemorrhoidal pile was 12.7 minutes, and the mean hospital-stay was 4.3 days. Acute and delayed postoperative anal bleeding occurred in 7 (1.1%) and 3 (0.5%) patients, respectively. The symptoms of both subsided spontaneously. Ninety-three (93) patients (14.3%) reguired nelaton catheterization for voiding difficulty, and one patient (0.2%) showed mild anal stenosis. The most frequent complaint was skin-tag formation (148 cases, 22.8%). In 140 cases, the skin tag was removed under local anesthesia. Conclusions: It is desirable to keep the normal structure of the anal canal by removing as little of the cushions as possible. Our 'lift-up submucosal hemorrhoidectomy' shows good results and is an easy operative method when compared with Parks’ original method.
