JOURNAL FREE ACCESSHuman esophageal squamous cell carcinoma(Es4). transplanted in subcutaneous tissue of nude mice, were treated with photodynamic therapy utilizing new photosensitizer, ATX-S10, and an excimer pumped dye laser. Five weeks later when the tumor grew up to a diameter of 7mm, ATX-S10 was injected intraperitoneally at a dose of 25mg per kg body weight to tumor-bearing mice.
Four hours later, the tumors were irradiated for 5 or 10 minutes with an excimer laser light (wavelength: 670nm). at conditions of 4.0mJ per pulse and 40Hz. Forty-eight hours later, mice were killed to investigate a tumor tissue. The histological findings of tumor, treated with PDT, showed massive necrosis with hemorrhage. The 7 days' observation of tumor, treated with PDT, revealed that all tumors were completely disappeared.View full abstractDownload PDF (1839K) -

JOURNAL FREE ACCESSThe main advantage of laser laparoscopic surgery is that it allows fertility surgeons to perform operative surgery by the minimally invasive approach with minimal adhesion, This article reviews the different tissue effects of different wavelength lasers and their applications in infertility surgery, especially in operative surgery for ectopic pregnancy and polycystic ovarian syndrome.View full abstractDownload PDF (898K) -

JOURNAL FREE ACCESSLaparoscopic surgery in gynecology is getting more popular in Japan with the clear recognition of many prognostic merits with these techniques, including less adhesions, short stay in hospital, and fast return to work. Another stimulating factor is the blooming effects to the society by broadcasting the Video recordings visualizing the remote controlled manipulations in the abdominal cavities with the aids of fascinating instruments such as 3-D CCD camera, glass-fiber, laser instruments, and image processing techniques. On the other hand, further clinical studies should be enhanced with the exact information on the side effects, complications, prognostic comparisons with those of traditional procedures. Another efforts should be focussed on the technical education of the doctors and pacemedics.View full abstractDownload PDF (320K) -

JOURNAL FREE ACCESSLaser have been applied to laparoscopic surgery in our institute since 1990. The methods for treating ovarian cysts are shown in this paper. Benign ovarian cysts diagnosed by careful preoperative examination including CT, ultrasound and tumor marker evaluation should be indications for laparoscopic surgery. Practically, 3-4 punctures are placed on the abdominal wall. Two basic methods, cystectomy and adnexectomy, are applied for ovarian cysts. For cystectomy, the capsule of the cyst is incised using laser after aspiration of the content, followed by separation of the cyst from the capsule with forceps. Laser coagulation is effectively used to stop minimal bleeding from the internal surface of the capsule after the separation procedure. The emptied capsule can be reformed to almost normal shape of ovary using fibrin glue. For adnexectomy, several methods have been introduced and used. The pedicle of the cyst can be severed to remove the adnex either by laser after ligation with loop sutures or by using Endo GIA. The other method is the coagulation of the mesoovarium and ovarianband followed by cutting with laser to remove the ovary.
Currently we use KTP/YAG laser which can generate two different kind of laser beams suitable for cutting and coagulation, making the operation procedure easy, safe and sure. Application of laser for laparoscopic surgery may be extended in future.View full abstractDownload PDF (581K) -

JOURNAL FREE ACCESSLaparoscopy has become an effective and precise diagnostic and treatment procedure in gynecology. It is particularly important to divide and separate tissues precisely and accurately without bleeding in laparoscopic surgery, The lasers such as KTP cut and coagulate simultaneously and can divide many tissues in the pelvis without bleeding. We have applied laparoscopic surgery with KTP laser for various gynecologic operations especially for the treatment of endometriosis: Laparoscopically assisted vaginal hysterectomy (LAVH) and cystectomy of chocolate cyst with laparoscopic adhesiolysis. In cases of LAVH for endometriosis, blood loss was significantly smaller compared with that for abdominal hysterectomy and the patients were discharged earlier after the surgery. Cystectomy for endometrial cyst takes significantly longer time but little blood loss compared with that of laparotomy. The results were at least equal or better compared with laparotomy for patients with stage-matched endometriosis. The procedure can not only minimize the amount of surgery for the patient. but also lead to a more rapid postoperative recovery while attaining the same objective as laparotomy. Thus, operative laparoscopy using KTP laser may be the treatment of choice for woman with endometriosis who need surgery.View full abstractDownload PDF (547K) -

JOURNAL FREE ACCESSSeventy cases with gynecological benign disease were treated with laparoscopy. Laser equipments (Nd: YAG, KTP/YAG, Ho: YAG), electrocautery (monopolar, bipolar, Argon beam coagulator) and Harmonic scalpel were used. For the treatment of ovarian tumor, drainage, ethanol fixation, ablation of lining, stripping of lining and adnexectomy were performed on them. For adhesion, lysis and/or TUSL (Transection of Utero Sacral Ligament) were underwent. For myoma and adenomyosis with adhesion, LAVH (Laparoscopically Assisted Vaginal Hysterectomy) was carried out.
In the study of dysmenorrhea, 67.4% (29 of 43) reported over 50% relief and 18.6% (8 of 43) reported no pain from menstrual pain after the surgery. Recurrent endometrioma was found in 55.0% (11 of 20) and residual cyst were found in 14.3% (1 of 6). Almost all of them were drained. All patients had no complaint after the LAVH. Their complications during and after the operation were minimal.
Our operative laparoscopy was suggested to be an effective treatment as a minimally invasive surgery.View full abstractDownload PDF (734K) -

JOURNAL FREE ACCESSOperations employing laser beams in the field of gynecology have been mainly performed under laparoscope. Since laparoscopic surgery is done in the closed and wet space with limited numbers of accessibilities. characteristics being needed for the laser beam are 1) to pass through water with limitied diminution. 2) to possess both cutting and coagulating abilities, and 3) not to require cooling of the tips, if used. For these reasons we have used a KTP laser. and have found its usefulness in the laparoscopic operations for endometriosis. ectopic pregnancy, and intraabdominal adhesion. KTP is effective not only in laparoscopic surgery but also in ordinary gynecologic operations such as vaginal hysterectomy. We describe the operation procedues employing KTP, discuss its advantages and disadvantages, and finally show the results of the operations.View full abstractDownload PDF (850K) -
