Videolaseroscopy and videolaparoscopy.

Laparoscopic surgery is not a new idea, but it has only recently found widespread acceptance. The introduction of technological advances such as improved light sources, lasers and video capability has made laparoscopy a surgical technique that offers many advantages to the patient and the surgeon. Because videolaseroscopy must be performed using a completely different set of skills, the only limit to the expansion of this type of surgery is training enough surgeons to meet the growing demands of the public. We believe that videolaseroscopy will become a larger part of the surgical operations performed in the future as technology becomes available to improve upon the instruments and methods.

Traumatic hypogastric artery bleeding controlled with bipolar desiccation during operative laparoscopy.

During multipuncture operative laparoscopy to excise peritoneal endometriosis involving the pelvic sidewall near the origin of the uterine artery, the lower portion of the hypogastric artery was perforated. The acute hemorrhage was controlled by immediately grasping the lacerated blood vessel with a 5-mm atraumatic grasping forceps. A Kleppinger bipolar forceps set at 25 W desiccated and sealed the artery successfully. As no further bleeding was noted, the procedure was terminated. The patient remained overnight for observation, and was discharged from the hospital the next day. She is doing well 18 months after the injury and repair.

Laparoscopic retropubic cystourethropexy.

STUDY OBJECTIVE: To evaluate the efficacy of laparoscopic retropubic urethrovesical suspension. DESIGN: Retrospective review of charts of 62 women over a follow-up period ranging from 8 to 30 months. SETTING: A suburban hospital in a major metropolitan area. PATIENTS: Sixty-two women, age 34 to 69 years, gravidity 0 to 8, and parity 0 to 7, with gynecologic abnormalities requiring surgical intervention and with pure genuine urinary stress incontinence. INTERVENTIONS: Each patient underwent a Burch or Marshall-Marchetti-Krantz procedure, modified to be performed at laparoscopy. MEASUREMENTS AND MAIN RESULTS: Success was measured subjectively and objectively. Subjective success, determined by the lack of need to wear pads, was 100%. Objective success was assessed using several criteria: comparison of preoperative and postoperative symptom diaries; questionnaires; urine characteristics by straight catheter (office dipstick for nitrate, leukocyte estrace, bacteria, and white cell blood count, if suspicious urine culture and sensitivity); postvoid residual volume (<100 ml was considered complete); urethrovesical junction angle as determined by catheter or Q-Tip placement (upward, downward, or straight); bladder support; and negative standing stress test. All women reported satisfactory relief of symptoms, with subjective and objective improvement. None have noted urinary leakage during activities similar to those preoperatively associated with this condition. CONCLUSION: To date, the outcomes have been acceptable, although the limited numbers and relatively short follow-up prohibit any definitive conclusions.

Life-threatening hypotension after vasopressin injection during operative laparoscopy, followed by uneventful repeat laparoscopy.

Vasopressin may be associated with systemic hemodynamic changes, including severe myocardial ischemia, even in healthy patients. A 36-year-old woman underwent laparoscopy for the treatment of a uterine leiomyoma. After intravascular injection of vasopressin, she experienced life-threatening hypotension, and the procedure was subsequently aborted. After she recovered, she underwent successful laparoscopy without the use of vasopressin, and no complications occurred. As endogenous vasopressin levels sometimes rise during laparoscopy, patients may become susceptible to the drug's effects, and appropriate precautions must be taken.

Laparoscopic repair of a vesicovaginal fistula: a case report.

BACKGROUND: Operative laparoscopy was performed for the management of ovarian remnant syndrome involving the bladder, bowel, vagina, and ureters, and requiring extensive dissection. A vesicovaginal fistula developed postoperatively. CASE: Because of the complexity and location of the fistula, a vaginal approach was not appropriate. Using techniques of videolaparoscopy, videocystoscopy, and operative laparoscopy, the fistula was repaired. CONCLUSION: In experienced hands, endoscopic management of complex vesicovaginal fistulas may be an alternative to the traditional abdominal approach.

Hospital cost comparison between abdominal, vaginal, and laparoscopy-assisted vaginal hysterectomies.

OBJECTIVE: To evaluate and compare the hospital charges for total abdominal hysterectomy (TAH), vaginal hysterectomy, and laparoscopy-assisted vaginal hysterectomy performed with the linear stapler. METHODS: Thirty cases of each of the three types of hysterectomies, performed at the same hospital by various surgeons, were selected at random. The authors did not participate in any of the cases evaluated. Operating room, postoperative hospitalization, and pharmacy costs were compared. Independent, two-tailed Student t test analysis was performed. RESULTS: The mean cost of performing laparoscopy-assisted vaginal hysterectomy with the linear stapler ($7161.66) was significantly higher (P < .05) than that of both vaginal hysterectomy ($4868.06) and TAH ($4926.80). The cost of vaginal hysterectomy was nonsignificantly lower (P > .05) than that of TAH. The mean operating room supplies and equipment charge for laparoscopy-assisted vaginal hysterectomy with the linear stapler ($2468.43) was, as expected, significantly higher (P < .05) than those for both abdominal ($716.65) and vaginal ($676.16) procedures. The average operating room time charge for laparoscopy-assisted vaginal hysterectomy ($1264.56) was also significantly higher (P < .05) than for the other two procedures (TAH $642.76, vaginal hysterectomy $955.66). The mean total pharmacy charges were similar for all groups ($1114.27 for laparoscopy-assisted vaginal hysterectomy, $1163.16 for vaginal hysterectomy, and $1098.71 for TAH). Reflecting the longer operating time for laparoscopy-assisted vaginal hysterectomy, the intraoperative pharmacy costs were significantly higher for this type ($417.00) than for the TAH patients ($290.62). The difference, however, was almost erased when postoperative pharmacy charges were included, reflecting the lower cost of a shorter hospital stay in the laparoscopy-assisted vaginal hysterectomy group. Some savings were realized by laparoscopy-assisted vaginal hysterectomy when postoperative hospitalization charges were considered. The average hospitalization time was 2.3 days for laparoscopy-assisted vaginal hysterectomy, 3.0 days for vaginal hysterectomy, and 3.3 for TAH. CONCLUSIONS: The cost savings expected with the advent of laparoscopy-assisted vaginal hysterectomy when performed with the linear stapler have not been realized at present. In most cost categories studied, the use of laparoscopy to perform a hysterectomy was associated with much higher costs. The predicted savings associated with the shorter hospital stay in these patients failed to offset the exorbitant intraoperative costs. However, when bipolar electrocoagulation with the CO2 laser and reusable instruments replace staplers and disposables, respectively, the projected savings are appreciated.

Laparoscopic amputation of a noncommunicating rudimentary horn after a hysteroscopic diagnosis: a case study.

This report describes the diagnosis and management of a noncommunicating rudimentary horn complicated by severe pelvic pain and associated endometriosis. This condition was diagnosed by simultaneous laparoscopic and hysteroscopic examinations. The hysteroscopic evaluation was significant in the diagnosis, as the noncommunicating horn was not recognized during a previous laparoscopy. The laparoscopic removal of the horn afforded complete long-term resolution of pain coupled with speedy postoperative recovery.

Laparoscopic Management of Genitourinary Endometriosis

We treated 17 patients with severe endometriosis involving the genitourinary tract. Eight women presented with persistent right or left flank pain, two presented with known ureteral obstruction, and five presented with urinary frequency and burning, and/or hematuria with their periods. Presented are the results of laparoscopic management in these patients. We performed segmental bladder resection in six patients and ureteral resection and reanastomosis in two. Nine additional patients underwent partial resection of the ureteral wall for complete removal of endometrial implants. The ureter was repaired with 4-0 PDS in seven patients and a stent was left in place for 4 to 6 weeks. Two required only a stent due to the small size of the ureterotomy. The postoperative course of these patients was uneventful. Following ureteral repair/reanastomosis, all women underwent an intravenous pyelogram at follow-up, and normal bilateral excretion was demonstrated. Cystoscopy revealed no abnormal findings in five patients who had undergone partial bladder resection. All patients reported significant pain relief or complete resolution of symptoms. Operative laparoscopy can be safely used to achieve relief from severe symptomatic endometriosis of the genitourinary tract.

Complications of 361 Laparoscopic Hysterectomies

We evaluated the results and complications of 361 hysterectomies performed at operative laparoscopy to treat a variety of benign gynecologic conditions. The hysterectomies were classified according to the number of steps performed endoscopically. There were no conversions to laparotomy for the hysterectomy, although one required laparotomy for rectosigmoid resection and anastomosis due to severe stricture of the rectosigmoid colon. There were no cases of mortality during the hospitalization nor during 42 postoperative days. The overall complication rate was 10.23 per 100 women. Intraoperative complications included three inferior epigastric vessel injuries, two hemorrhages requiring blood transfusion, one small bowel injury and one bladder injury. The overall complication rate in this series is lower than that reported for abdominal or vaginal hysterectomy. Laparoscopically assisted hysterectomy allows the surgeon to directly visualize uterine artery pedicles, to clearly delineate ureteral paths, to accomplish immediate and precise hemostasis, to use hydrostatic lavage and irrigation to continuously disperse microclots and tissue debris, and to operate with accuracy. While this procedure seems to offer several advantages such as reduced devitalized tissue, near elimination of the potential for suture reaction, and diminished inflammatory responses during the healing phase, complications can be encountered.

Adhesion formation after endoscopic posterior colpotomy.

Twenty-two women who had undergone laparoscopic posterior colpotomy at initial operative laparoscopy and later underwent a second laparoscopic procedure were evaluated for adhesion formation. Fifteen women (68%) had myomata removed, 3 (14%) had a dermoid cystectomy, 1 (5%) had a serous cystadenoma removed, and 3 (14%) who had large endometriomata and severe adhesions underwent salpingo-oophorectomy. Although filmy adhesions were noted in nine women, no adhesions were noted in the cul-de-sac. Based on our limited results, it does not appear that tissue removal via laparoscopic colpotomy predisposes reproductive-age women to postoperative adnexal adhesion formation.

Four ovarian cancers diagnosed during laparoscopic management of 1011 women with adnexal masses.

OBJECTIVES: This study was conducted to assess the value of laparoscopic management of adnexal masses. Two concerns we wish to address are the failure to diagnose early ovarian cancer at laparoscopy and worsening the prognosis of stage I cancer by spilling fluid during surgery. STUDY DESIGN: The setting is a predominantly referral-based, private subspecialty practice. All operations were preformed in the outpatient surgical suite of a large suburban hospital. After extensive patient screenings, which included history and physical examination, preoperative serum CA 125 levels (since 1988), and pelvic ultrasonography, 1209 adnexal masses were managed laparoscopically. RESULTS: Of 1011 patients with surgical management, ovarian cancer was discovered intraoperatively in four. CONCLUSIONS: Our findings indicate that with consistent use of frozen sections of all cyst walls and suspicious tissue, laparoscopic management did not alter the prognosis. Neither CA 125 level, pelvic ultrasonography, nor peritoneal cytologic testing had sufficient diagnostic specificity to predict malignancy. Experienced surgeons using intraoperative histologic sampling may safely evaluate adnexal mass laparoscopically.
