Effects of pneumoperitoneum and position changes on blood pressure variability and heart rate variability during laparoscopy-assisted vaginal hysterectomy / 대한마취과학회지

BACKGROUND: This study was designed to assess the effects of pneumoperitoneum and positional changes on the autonomic nervous system (ANS) in laparoscopy-assisted vaginal hysterectomy (LAVH) patients. METHODS: Systolic blood pressures and R-R interval were recorded for 5 minutes in 22 patients, and then power spectral analyses were conducted to evaluate the ANS. The following variables were measured at various positions: preinduction (BASE), prepneumoperitoneum (PREPP), pneumoperitoneum at head-down (PP), normoperitoneum at supine (POSTPP). RESULTS: High frequency of heart rate variability (HRVHF), Low frequency of heart rate variability (HRVLF), Low frequency of blood pressure variability (BPVLF), LF/HF ratios of HRV (LFHFr) were significantly lower than that of BASE at PREPP. HRVHF, HRVLF, BPVLF were significantly lower than that of BASE at PP. At PP, normalized HF of HRV (nuHF) is significantly lower than that of BASE and normalized LF of HRV (nuLF) is significantly higher than that of BASE and PREPP (P < 0.05). LFHFr was significantly lower than that of BASE and significantly higher than that of PREPP at PP. At POSTPP, HRVHF, HRVLF, BPVLF were significantly lower than that of BASE. But, BPVLF at POSTPP was higher than that of PP. CONCLUSIONS: We conclude that the pneumoperitoneum and trendelenburg positions caused sympathetic activation in LAVH patients.

Two Cases of Extrapelvic endometriosis following Laparoscopy-assisted vaginal hysterectomy and Cesarean section / 영남의대학술지

Extrapelvic endometriosis is a rare disease. The majority of extrapelvic endometriosis cases involve scar tissue following obstetric and gynecologic procedures. We have treated two cases of extrapelvic incisional endometriosis. A 39 year old female patient with cyclic vaginal spotting after laparoscopic assisted vaginal hysterectomy due to uterine myoma and a 35 year old female patient with a painful palpable abdominal mass after cesarean section. Both underwent complete excision and were proven to have endometriosis by pathology. Here we report on both cases and review the medical literatures.

A Clinical Study on 570 Cases of Laparoscopy Assisted Vaginal Hysterectomy (LAVH) / 대한산부인과학회잡지

OBJECTIVE: To evaluate the clinical outcome and characteristics of laparoscopy assisted vaginal hysterectomy (LAVH) in gynecologic patients. METHODS: From September, 2001 to February, 2004, total 570 cases of patients were performed LAVH at Gacheon medical school Ghil Hospital. We reviewed medical records and analyzed these cases about age, parity, weight, previous surgery history, operation indication, operation outcome, duration of hospitalization and complication. RESULTS: The results of this study summarized as follows. The mean age of patients was 46.4 +/- 7.2 years old. Average parity of patients was 2.4 +/- 1.4. Average weight of patients was 63.4 +/- 8.2 kg. Previous operation history was 195 cases (34.2%). Most common operation indication was uterine leiomyoma, followed by adenomyosis, combination of leiomyoma and adenomyosis and endometriosis. The mean operation time was 72 +/- 20.6 minutes. The mean duration of hospitalization was 4.5 +/- 0.6 days. The major complication of operation was trocar site bleeding, followed by bladder injury, bowel injury, and ureteral injury. CONCLUSION: LAVH is safe and useful. So it is recommendable to gynecologic patients.

Endoscopic management of uterine myoma

This study was undertaken to evaluate the various gynecologic endoscopic surgical techniques including resectoscopic myomectomy, laparoscopic myomectomy, and laparoscopy assisted vaginal hysterectomy (LAVH) used in the treatment of uterine myomas. The medical records of 136 cases of uterine myomas treated using one or more of the gynecologic endoscopic surgical techniques in the Department of Obstetrics and Gynecology at Yonsei University were retrospectively reviewed from March 1997 to September 1998. Of the 136 cases reviewed, there were 40 submucosal myomas and 96 intramural and subserosal myomas. For statistical analysis, Student's t-test was used. Submucosal myomectomy using the resectosope was performed in 35 cases (mean age: 39 +/- 1.5 years), laparoscopic myomecotmy in 35 cases (mean age: 36 +/- 1.9 years), and LAVH in 66 cases (mean age: 42 +/- 1.1 years). In cases of huge myomas, the GnRH agonist was used prior to surgery, and in cases of heavy uterine bleeding, angioblock of the uterine artery was undertaken before the endoscopic procedures. The mean operating time was significantly shorter in resectoscopic myomectomy (41 +/- 12 min), followed by laparoscopic myomectomy (85.0 +/- 10.3 min) and LAVH (123 +/- 5.3 min). The mean hospital stay for resectoscopic myomectomy, laparoscopic myomectomy, and LAVH was 1.9 +/- 0.5, 2.5 +/- 0.5, and 3.4 +/- 0.8 days (p < 0.001), respectively. There were 3 cases of complications including pulmonary edema and uterine perforation in the resectoscopic myomectomy group, and 4 cases of complications including bladder, ureter, and epigastric vessel injury in the LAVH group. In conclusion, the therapeutic effect of various gynecologic endoscopic surgical techniques can be maximized in terms of shorter operation time, shorter hospital stay, faster recovery, and less blood loss by the appropriate management of uterine myoma in well-chosen patients.
