Laparoscopically assisted vaginal hysterectomy using 3-trocar method through the previous operation scar for large uterus weighing 300 g or more / 대한산부인과학회지

OBJECTIVE: The purpose of this study is to examine the feasibility and safety of laparoscopically assisted vaginal hysterectomy (LAVH) using 3-trocar method through the previous operation scar for uterus weighing 300 g or more in the management of gynecologic disease. METHODS: This retrospective study was peformed in 51 cases of LAVH with uterus weighing 300 g or more and with symptomatic benign gynecologic diseases (leiomyoma or adenomyosis). LAVH was performed through 3-trocar method (one trocar below the umbilicus, and two trocars at the point about 2 cm above and medial side of each anterior superior iliac spine, or at the bilateral edges of the previous operation scar). RESULTS: Previous operation history was found in 17 cases (33.3%) and cesarean section was the most common. There was no difference in the age, body mass index, parity, length of operation, amount of blood loss, hemoglobin change, length of gas out, and hospital stay, rate of transfusion and complication between two groups divided by history of operation (P>0.05). Uterine weight in the group having operation history was lighter than that in group having not operation history (519.91+/-220.53 g and 381.24+/-70.63 g, respectively, P<0.05). CONCLUSION: LAVH for large uterus weighing 300 g or more using 3-trocar method through previous operation scar is safe and effective operation method, and may be an alternative to abdominal hysterectomy in selected patients.

Evaluation of 110 cases of single-port access laparoscopically assisted vaginal hysterectomy (SPA-LAVH) and comparison with multi-port access / 대한산부인과학회지

OBJECTIVE: To evaluate the safety and feasibility of single-port access laparoscopically assisted vaginal hysterectomy (SPA-LAVH) using conventional laparoscopic instruments compared to multi-port access laparoscopically assisted vaginal hysterectomy (MPA-LAVH). METHODS: We reviewed the medical records of 220 patients with uterine leiomyoma or adenomyosis who underwent 110 SPA-LAVH and 110 MPA-LAVH in Incheon St. Mary's Hospital between April 2007 and November 2009. We performed SPA-LAVH with conventional rigid straight laparoscopic instruments in all cases. We also performed a new vaginal cuff closure method, Kim's Vaginal Vault Suspension Method, named after the operator (Kim, YW) in both SPA-LAVH and MPA-LAVH. RESULTS: There was no significant difference in patients' age, operating time, uterine weight, hemoglobin change, frequency of blood transfusion, and incidence of postoperative fever between the two groups. The patients' mean age was 46.1+/-7.0 years (SPA-LAVH) and 45.5+/-6.3 years (MPA-LAVH). The mean operating time was 87.2+/-21.0 minutes (SPA-LAVH) and 83.3+/-20.3 minutes (MPA-LAVH). The mean uterine weight was 261.4+/-139.7 g (SPA-LAVH) and 257.8+/-132.9 g (MPA-LAVH). The mean hemoglobin change was 1.1+/-0.7 g/dL (SPA-LAVH) and 1.2+/-0.6 g/dL (MPA-LAVH). Neither bowel injury nor urinary tract injury occurred during the operation in the two groups. One of the SPA-LAVH and one of the MPA-LAVH cases were converted to abdominal total hysterectomy. The mean hospital stay time was shorter with SPA-LAVH (2.6+/-0.6 days [SPA-LAVH] and 3.3+/-0.7 days [MPA-LAVH], P<0.05). CONCLUSION: SPA-LAVH using conventional rigid straight laparoscopic instruments can be offered as a safe and feasible alternative to MPA-LAVH.

Clinical comparisons of laparoscopically assisted vaginal hysterectomy and total vaginal hysterectomy / 대한산부인과학회지

OBJECTIVE: To compare the clinical results between laparoscopically assisted vaginal hysterectomy (LAVH) and total vaginal hysterectomy (TVH). METHODS: We reviewed the medical records of patients who underwent LAVH and TVH from January 2002 to December 2004 in 00 university hospital without the history of uterine prolapse or pelvic relaxation. We evaluated age, parity, previous abdominal operations, indication of hysterectomy, size of the uterus, operation time, hemoglobin change, hospital day, the degree of postoperative pain and initiation of diet and postoperative complications. RESULTS: The age and parity of the patients in both groups were not different statistically. There were history of previous abdominal operations in 20.8% of LAVH group and 25.3% of TVH group which didn't have statistic significance. Major indications of the operation were uterine myomas in both groups. The average weight of the extracted uterus were 272.9+/-114.5 gm and 225.6+/-87.0 gm in the LAVH group and the TVH group respectively which had significance, and the operation time were 81.1+/-23.4 minutes and 71.1+/-37.8 minutes respectively which had significance. There were no difference in the hemoglobin drop of the postoperative day 1, but the hemoglobin drop of the postoperative day 4 was larger in the LAVH group. Postoperative complications occurred more often in the TVH group (15.2%) than LAVH group (11.9%) but didn't have significance, and the complications were treated by conservative managements and observation of the progress. And also the hospital day, the degree of postoperative pain and initiation of diet had no significance. CONCLUSION: Both LAVH and TVH had no statistic difference in the postoperative morbidity and recuperation. Moreover the indications of operation for both surgeries had no statistic difference, but LAVH had a preference for the larger size of uterus. Furthermore in order to increase the satisfactions of patients and remedy the weak points of procedures, research on the indications and contra-indications between the operative approaches and training on the operative procedures are required.

Comparison study on results of LAVH according to prior abdominal surgery / 대한산부인과학회지

OBJECTIVE: To evaluate the result of laparoscopically assisted vaginal hysterectomy (LAVH) according to history of prior abdominal surgery. METHODS: From January, 2003 to June, 2005, a total of 504 patients were performed LAVH at our Hospital. The patients were divided into 2 groups: Group of non prior abdominal surgery (Op. Hx(-) group) included 262 cases and group of prior abdominal surgery (Op. Hx(+) group) had 242 cases. We reviewed medical records and analyzed these cases regarding age, parity, weight, height, operation indication, operation outcome, duration of hospitalization and complication. RESULTS: There were no differences in terms of patients' mean age, parity, weight and height, and indications for surgery between the two groups. Mean operation time of Op. Hx(+) group (86.9+/-28.2 min) was longer than Op. Hx(-) group (80.7+/-20.0 min). There was no statistical difference on mean postoperative hemoglobin drop and mean uterine weight between the 2 groups. Mean hospital stay of Op. Hx(+) group (4.6+/-1.7 days) was longer than Op. Hx(-) group (4.3+/-0.9 days). The incidence of major surgical complications was higher in Op. Hx(+) group (10 cases - 4.1%) than Op. Hx(-) group (3 cases - 1.2%). In case of blader injury, Op. Hx(+) group (5 cases) was higher than Op. Hx(-) group (0 case). Op. Hx(+) group had 2 ureteral injuries and 1 rectal injury but there were no statistical differences. In case of trocar site bleeding, both group had 2 cases trocar site bleeding respectively. Op. Hx(-) group had 1 inferior vena cava injury but there was no statistical difference. CONCLUSION: At the time of LAVH, the incidence of bladder injury was higher in group of patients with history of prior abdominal surgery. So special attention should be paid to prevent bladder injury.

Effects of a Crystalloid Preload on Hemodynamics after Pneumoperitoneum in Laparoscopically-Assisted Vaginal Hysterectomy (LAVH) / 대한마취과학회지

BACKGROUND: Pneumoperitoneum and head-down tilt during a laparoscopic hysterectomy causes significant alterations in the hemodynamics including decreased cardiac output. The aim of this study was to evaluate the effects of a crystalloid preload on the hemodynamics after a hysterectomy (LAVH). METHODS: The patients were randomized to receive either no crystalloid fluid preload (control group: 29 women) or 10 ml/kg of a crystalloid fluid preload over 10 min (preloading group: 30 women) before the pneumoperitoneum. The hemodynamic parameters were measured before inducing anesthesia, immediately after the tracheal intubation, before the skin incision, and 2, 5, 10, 20, and 30 min after the pneumoperitoneum with CO2 with noninvasive cardiac output measurements using the partial CO2 rebreathing method. RESULTS: The cardiac index (CI) was reduced 2 and 5 min after the pneumoperitoneum, and then returned to normal. There were no significant differences in the CI after the pneumoperitoneum between the two groups (P<0.05). CONCLUSIONS: The administration of a 10 ml/kg crystalloid preload did not attenuate the decrease in the CI after pneumoperitoneum.

Correlations between Mean Arterial Blood Pressure, Cardiac Index, and Systemic Vascular Resistance Index in Laparoscopically-assisted Vaginal Hysterectomy (LAVH) / 대한마취과학회지

BACKGROUND: The purpose of this study was to evaluate the correlations between mean blood pressure (MBP), cardiac index (CI), and systemic vascular resistance index (SVRI) in patients undergoing laparoscopically-assisted vaginal hysterectomy (LAVH). METHODS: The authors enrolled 47-female patients prior to a LAVH. Hemodynamic parameters were measured before anesthetic induction, just after tracheal intubation, before skin incision, and 2, 5, 10, 20, and 30 min after pneumoperitoneum with CO2 by noninvasive cardiac output measurement using the partial carbon dioxide rebreathing method. RESULTS: CI was significantly reduced 2 and 5 min after pneumoperitoneum (2.6 +/- 0.7 L/min/m2, and 2.5 +/- 0.7 L/min/m2, respectively), and then returned to the pre-skin incision level. SVRI increased significantly after pneumoperitoneum and was then restored to that measured pre-skin incision at 20 min after pneumoperitoneum. MBP before anesthetic induction was found to be correlated with CI at 20 and 30 min after pneumoperitoneum (R = 0.37, P = 0.022, R = 0.37, P = 0.036, respectively). A moderate correlation was observed between MBP before anesthetic induction and SVRI at 2, 5, 10, 20, and 30 min after pneumoperitoneum (R = 0.39 0.60, P < 0.05). CONCLUSIONS: MBP before anesthetic induction correlated with CI at 20, and 30 min after pneumoperitoneum and with SVRI at 2, 5, 10, 20, and 30 min after pneumoperitoneum. Howerer, reduced CI at 2, 5, and 10 min after pneumoperitoneum was not correlated with MBP before anesthetic induction.

Clinical Evaluation on 154 Cases of Laparoscopically Assisted Vaginal Hysterectomy (LAVH) / 대한산부인과학회잡지

OBJECTIVE: To evaluate the indications, advantages and complications of laparoscopically assisted vaginal hysterectomy (LAVH), retrospectively. METHODS: From Mar. 2003 to Feb. 2004, clinical trials of LAVH (n=154) were performed in the Department of Obstetrics and Gynecology, Kangbuk Samsung Medical Center, School of Medicine, University of Sungkyunkwan, Seoul, Korea. Medical records of patients who underwent LAVH were reviewed. The results were evaluated according to characteristics of patients, history of previous abdominal surgery, preoperative surgical indications, postoperative diagnosis, mean operation times, weight of uterus, change of hemoglobin, hospital stay, associated diseases, concomitant procedures and complications. RESULTS: The mean age was 46.09 +/- 6.67 years. The mean parity was 2.08 +/- 0.94. Tubal ligation, vaginal bleeding, leiomyoma was the most common previous abdominal surgery, preoperative surgical indication, and postoperative diagnosis, respectively. The mean operation time was 130.66 +/- 67.68 minutes. The mean uterine weight was 259.27 +/- 123.48 gm. The mean hemoglobin change was 1.61 +/- 1.12 g/dL. The mean hospital stay was 3.44 +/- 1.83 days. The complication rate was 3.2% (5 cases); bladder injury (3 cases) being the most common complication. CONCLUSION: LAVH appears to be beneficial in many aspects. The further development of laparoscopic instruments and skills will reduce limitations and complications of LAVH and will hopefully allow the utilization of this technique to expand to include other clinical indications and concomitant procedures.

Clinical Consideration on the Method of Hysterectomy / 대한산부인과학회잡지

OBJECTIVE: The most common operation in gynecology is hysterectomy. To compare the indications, patient characteristics and clinical outcome, complication between total abdominal hysterectomy (TAH) and vaginal total hysterectomy (TVH), laparoscopically assisted vaginal hysterectomy (LAVH). METHODS: This study was designed to analyze 147 patients of TAH (Group I) from January 2003 to September 2003, 48 patients of TVH (Group II), 108 patients of LAVH (Group III) at Eulji medical center of obstetrics and gynecology from January 2002 to September 2003. We analyzed the result with patient characteristics, parity, medical disease, history of previous operation, indication of hysterectomy, uterine weight, concurrent surgical procedure, operation time, bleeding amount, complication and length of hospital stay. Uterine prolapse was excluded in the analysis of this study. RESULTS: Patient characteristics, parity, medical disease were no differences. Number of previous operation were 63 cases (42.9%) in TAH group, 10 cases (20.8%) in TVH group, 43 cases (39.8%) in LAVH group, and the most common of operation was tubal ligation in three gropups. Most common indication of hysterectomy was uterine leiomyoma. The mean uterine weight was 374.31 +/- 250.26 gm in TAH group, 187.70 +/- 109.62 gm in TVH group and 203.26 +/- 94.92 gm in LAVH group. The mean operation time was 89.61 +/- 25.24 min in TAH group, 73.39 +/- 21.80 min in TVH group and 96.18 +/- 27.98 min in LAVH group. Postoperative complication was observed 60 cases (40.8%) in TAH group, 8 cases (16.7%) in TVH group, 19 cases (17.6%) in LAVH group. Most common complication was bleeding and required transfusion (TAH 32 cases (21.8%), TVH 3 cases (6.3%), LAVH 10 cases (9.3%)). CONCLUSION: LAVH and TVH present superior result in terms of complication when compared with TAH. LAVH and TVH have advantage of lower morbidity, less pain, shorter hospital stay and convalescence. LAVH should be considered when the vaginal approach is unfeasible, showing clear advantages over abdominal hysterectomy.

A Clinical Analysis of Laparoscopically Assisted Vaginal Hysterectomy (LAVH) / 대한산부인과학회잡지

OBJECTIVE: To report our experience with laparoscopically assisted vaginal hysterectomy (LAVH) and evaluate the advantages of LAVH. This is a retrospective study. METHODS: From Jan. 2001 to Aug. 2002, 204 LAVHs were performed at the Department of Obstetrics and Gynecology, Our Lady of Mercy Hospital, The Catholic University of Korea. We studied the results with regard to the age, parity, previous abdominal surgery, surgical indications, operation time, weight of uterus, change of hemoglobin, hospital stay, concomitant procedures, and complications. RESULTS: The mean age was 43.9+/-6.4 years. The mean parity was 2.1+/-1.3. Tubal ligation was most common previous abdominal surgery. As a surgical indication, leiomyoma (52.9%) and adenomyosis (33.3%) were more common indications than any other gynecological problem. The mean operation time was 85.7+/-22.4 minutes. The mean uterine weight was 206.2+/-103.7 g. The mean hemoglobin change was 1.2+/-0.7 g/dl. The mean hospital stay was 3.3+/-0.8 days. Unilateral salpingoophorectomy was most common operation as concomitant procedure. Surgical complication rate was 3.4%. CONCLUSION: LAVH is a safe and effective alternative to abdominal hysterectomy with advanced technologic development in laparoscopic instruments and skills.

Comparison study of VTH and LAVH for the indications other than uterine prolapse / 대한산부인과학회잡지

OBJECTIVE: To compare the advantages and disadvantages between total vaginal hysterectomy (VTH) and laparoscopically assisted vaginal hysterectomy (LAVH) including the indications and safety. METHODS: We reviewed the medical records of patients who underwent VTH from July 1998 to December 1999 and those who underwent LAVH from January 2000 to April 2002. We evaluated age, parity, previous abdominal operations, indications for hysterectomy, combined operations, operation time, bleeding amount, hemoglobin change, weight of uterus, and postoperative complications. RESULTS: 1. Age was not a notable factor but parity was significantly lower in LAVH group. 2. In VTH group, 48% of patients had previous operations compared with 46% in LAVH group. 3. The most common indication for hysterectomy of both group was uterine myoma. 4. The weight of hysterectomized specimen was 256 g in VTH group and 237 g in LAVH group. 5. In VTH group, 38% received concurrent surgical procedures of which colporrhaphy was the most common (14 cases). In LAVH group, 72.5% received concurrent surgical procedures of which salpingoo- phorectomy was most common. 6. The operation time showed a notable difference; 78.6 min. in VTH group and 105.4 min. in LAVH. 7. There was no significant difference in bleeding amount and hemoglobin change. 8. Postoperative complication was higher in VTH group (14%) than LAVH group (7.5%). However all the patients recovered with conservative treatment and close observation. CONCLUSION: Both VTH and LAVH had the following advantages compared with abdominal hysterectomy: less pain, shorter hospital stay, cosmetic advantages, lower prevalence. In this study we found out that in VTH, the procedure could be done safely even if the uterus was big or with previous abdominal operations. Limited operation field and the fact that we couldn't check the abdominal cavity were some disadvantages. In comparison, LAVH offered a view of the abdominal cavity which make easy adnexal operation but because of expensive operative tools, cost was a problem. In order to satisfy the patient and lower the cost, appropriate study on the indications and training on procedures will be necessary.

The Effect of Preoperative Clonidine in a Laparoscopically-Assisted Vaginal Hysterectomy / 대한마취과학회지

BACKGROUND: Laparoscopic surgery is a technique with cosmetic advantage, reduction of hospital days, postoperative pain and morbidity. However, in terms of anesthetic care, increase of airway pressure and blood pressure, decrease of ventilatory capacities, and hypercarbia have been problematic issues. The purpose of this study was to evaluate the effect of preoperative administration of clonidine for controlling blood pressure during laparoscopic surgery. METHODS: Forty patients who underwent a laparoscopically-assisted vaginal hysterectomy were randomly allocated into clonidine administered group (group C) or a control group (group N) before the operation. Clonidine 0.15 mg was given intravenously for group C patients, then induction was started. Blood pressure and pulse rates were measured at times of entering the operating room, intubation, post-intubation 1, 3, and 5 minutes, post-insulfflation 10 minutes, and postoperatively 1 hour. Blood sugar was checked at post-insulfflation 10 minutes and postoperatively 1 hour. RESULTS: In both groups blood pressure and pulse rate increased significantly compared to the control value after intubation and this feature continued to post-intubation 1 minute in group N. There was significant increase of blood pressure in the postoperative 1 hour period only in group N. Blood sugar also increased significantly at post-insufflation 10 minutes in group N and 1 hour in both groups. Comparing the two groups, blood pressure values of group N at postintubation 1, 3, and 5 minutes were significantly higher than group C, and pulse rate at postinsuflation 1 hour was significantly higher than group C. In addition, the blood sugar in group N was significantly higher than group C at postinsufflation 10 minutes. CONCLUSIONS: Preoperative clonidine administration is an effective and convenient method to control hypertension and the blood sugar level during laparoscopic surgery.
