Ambulatory hemorrhoidectomy with CO2 laser.

Center, Valhalla, New York, USA.
PURPOSE: This study was undertaken to evaluate ambulatory hemorrhoidectomy
using the CO2 laser. METHODS: Ninety consecutive patients (50 males,
40 females), 80 percent of whom had second or third degree hemorrhoids,
had ambulatory hemorrhoidectomy performed with a CO2 laser in the left
lateral Sims position under local anesthesia and intravenous sedation.
Dissection was entirely performed with the CO2 laser using an open technique.
RESULTS: One patient with polycythemia vera was admitted subsequently
for secondary hemorrhage. All but three patients had healed within four
weeks. No long-term sequelae were encountered. CONCLUSION: These results
compare favorably with those obtained by others and show that ambulatory
laser hemorrhoidectomy may simplify management in selected patients.

[Outpatient hemorrhoidectomy using the CO2 laser]
In the free standing center of ambulatory surgery of Nice, proctology
with carbon dioxide laser is a basic activity. Among 177 cases of
proctology operated during 1989, we find 91 hemorrhoidectomies realized
with CO2 laser in strictly ambulatory surgery (no hospitalization).
This work's interet is demonstrating adaptation to the laser makes many
advantages to the classic operation of Milligan and Morgan: simplification
of the surgical technique easy post-operative course, no hospitalization
and quicker return to work, leading to a lower cost of this pathology.
Complications are rare and excellent results noted.

The role of lasers in hemorrhoidectomy.

Abstract: Laser hemorrhoidectomy patients had less pain, less constipation,
less urinary retention, and spent less time in the hospital than traditional
Eighty-eight patients who received treatment for hemorrhoids were randomized
into two groups. Group A received the Nd-YAG laser phototherapy for
internal hemorrhoid combined with the CO2 laser for external hemorrhoid.
Group B was treated with closed Ferguson hemorrhoidectomy. The need
of narcotic injections for pain relief was 11 percent in group A vs.
56 percent in group B (P less than 0.001). The incidence of postoperative
urinary retention was 7 percent in group A, vs. 39 percent in group
B (P less than 0.05). No enema was required postoperatively in group
A, vs. 9 percent in group B; 84 percent of the patients in group A were
discharged on the second postoperative day, vs. 83 percent of the patients
in group B discharged on the fifth postoperative day. The cost was 20
percent less in the former group.

The laser treatment of hemorrhoids: results of a study on 1816 patients.

Laser is an effective, simple and harmless clinical procedure used
for the treatment of hemorrhoids, as an alternative to medical therapy
or surgery. In this report, we describe our experience of applying carbon
dioxide laser to hemorrhoids in a total 1816 consecutive patients. The
results lead us to conclude that the laser treatment of hemorrhoids
is effective in pain alleviation from the first session and that
patients so treated have a much more comfortable postoperative course.

Skobelkin OK, Tolstykh PI, Derbenev VA, Ste'nko VG, Kochurkov NV.
Results of the surgical treatment of 556 patients with different
diseases of the anorectal area with the help of CO2 laser are presented.
Functional results were good, the amount of postoperative complications
was 1.5 times less, recurrences were half less, the time of intrahospital
treatment was 1.5 day shorter, the period of ambulatory rehabilitation
3.8 days shorter.

CO2 laser haemorrhoidectomy--does it alter anorectal function or decrease
pain compared to conventional haemorrhoidectomy?

Carbon dioxide (CO2) laser haemorrhoidectomy is feasible and safe provided
it is used with care. It is associated with a reduced requirement
for post-operative analgesia. The CO2 laser caused no significant
alteration in anorectal physiology.
Dr. Gerald Kirshenbaum, Aurora, CO and Dr. Allen Snyder, Pittsburgh,
It is a simple, rapid, and remarkably effective procedure. These doctors
report that the procedure is significantly shorter with the Contact
Laser technique, taking approximately 20 minutes for one large hemorrhoid
and about 45 minutes for three. Following cold knife, electrocautery,
or non-contact laser hemorrhoidectomy, patients typically remain in
the hospital for 3-5 days and leave in considerable discomfort. Following
Contact Laser hemorrhoidectomy, the typical patient will return home
the same day, by 3 or 4 days they are moving their bowels without
undue pain or difficulty, and they can return to their normal routine
by 7-10 days post-operatively.
Both physicians find a marked difference in pain compared to traditional
techniques. Though it is not clear which aspects of the procedure
are responsible for this reduction in post-surgical symptoms, the total
procedure using this technique appears to have a positive impact on
the patient's recovery. There is less tissue damage and muscle
stimulation than with other methods, the laser seals lymphatics so that
there is markedly less edema, and there is some belief that the
laser energy may also seal nerve endings
