Prognostic value of pre-treatment human papilloma virus DNA status in cervical cancer.

OBJECTIVE: Although the relationship between human papilloma virus (HPV) and cervical cancer is well established, the prognostic value of HPV status has not been determined, largely because previous studies have yielded conflicting results. This study aimed to investigate the prognostic value of pre-treatment HPV DNA for predicting tumor recurrence in cervical cancer. METHODS: The study included 248 eligible patients who provided cervical cell specimens for HPV genotyping before surgery or concurrent chemoradiotherapy (CCRT). Of these 248 patients, 108 were treated with radical hysterectomy for International Federation of Gynecology and Obstetrics (FIGO) stage IB1-IIA cervical cancer, and 140 were treated with CCRT for FIGO stage IB2-IV cervical cancer. RESULTS: HPV 16 and 18 were the two most common HPV types detected, with prevalence rates of 52.4% and 12.5%, respectively. The pre-treatment HPV DNA test showed that 18.5% of cervical cancers were HPV negative. Multivariate analysis showed that HPV negativity was associated with poorer disease-free survival (DFS) than HPV-positive status (hazard ratio [HR], 3.97; 95% confidence interval [CI], 1.84-8.58; p=0.0005), and patients with HPV 16-positive cancers had better DFS (HR, 0.41; 95% CI, 0.23-0.72; p=0.0019). In the surgery group, only HPV 16 positivity was significantly correlated with DFS (HR, 0.34; 95% CI, 0.12-0.96; p=0.0416). In the CCRT group, only HPV negativity was significantly correlated with DFS (HR, 3.75; 95% CI, 1.78-7.90; p=0.0005). CONCLUSIONS: Pre-treatment HPV DNA status may be a useful prognostic biomarker in cervical cancer. The presence of HPV 16 DNA was associated with better DFS, and HPV negativity was associated with worse DFS. However, larger sample sizes and more comprehensive studies are required to verify our findings.

Conservative Treatment for Patients with Carcinoma in Situ-Positive Margins After a Loop Electroexcisional Procedure: Is It Safe?

OBJECTIVE: To investigate the clinical significance of and appropriate treatments for carcinoma in situ (CIS)-positive margin after a loop electroexcisional procedure (LEEP) in the management of squamous carcinoma in situ (SCIS), adenocarcinoma in situ (ACIS), and microinvasive carcinoma (MIC). STUDY DESIGN: We analyzed 232 patients who underwent a hysterectomy for CIS-positive margin. We investigated the relationship between residual lesions after hysterectomy and clinical parameters, including age, LEEP method, histologic grade of conized cervix, location of the positive margin after LEEP, results of endocervical curettage (ECC), and size of the conized specimen. RESULTS: Age, LEEP method, proximal endocervical margin positivity, and ECC positivity differed significantly between patients with residual lesions and those with no residual lesions. In a comparison between groups with residual disease of a higher or lower grade than MIC, age, LEEP method, ECC positivity, and histologic grade of conized cervix were significantly different. Age, histologic grade of conized cervix, and ECC positivity were clinical parameters significantly contributing to invasive residual lesion in multivariate regression analysis. There were no residual invasive (MIC or advanced invasive cancer) lesions observed in women <50 years old who had SCIS conized lesions after hysterectomy. CONCLUSION: Conservative treatment with close follow-up or reconization for women <50 years old who have conized SCIS lesions without ECC positivity is acceptable. However, this study does not present sufficient evidence for the conservative treatment of conized ACIS or MIC lesions with CIS-positive margins.

Long-Term Efficacy of Laparoscopic or Robotic Adenomyomectomy with or without Medical Treatment for Severely Symptomatic Adenomyosis.

BACKGROUND/AIMS: To determine the long-term efficacy of laparoscopic or robotic adenomyomectomy with or without gonadotropin-releasing hormone (GnRH) for the treatment of severely symptomatic adenomyosis. METHODS: Between August 2008 and May 2011, we prospectively observed 33 patients who underwent laparoscopic or robotic adenomyomectomy with uterine artery ligation for the treatment of symptomatic adenomyosis. Seventeen patients (52%) received 3-course GnRH agonist treatment after the adenomyomectomy. RESULTS: The mean operating time was 147.4 ± 52.0 min, and the mean blood loss was 36.1 ± 37.4 ml. Postoperative complications occurred in 5 patients, including 4 cases of febrile morbidity, 1 case of ileus and 1 case of pelvic abscess. Patients had statistically significant symptom relief during the 3-year follow-up period. Four of the 33 patients (12%) showed symptom relapse; 3 patients showed a relapse with dysmenorrhea and 1 patient showed a relapse with menorrhagia. There were no significant differences in terms of therapeutic outcomes between surgical-only and surgical-medical treatment. CONCLUSION: Laparoscopic or robotic adenomyomectomy was feasible and safe for women with severely symptomatic adenomyosis who requested uterine preservation. Moreover, this procedure provided long-term symptom control, regardless of postoperative GnRH agonist administration.

Total vaginal and single-port total laparoscopic hysterectomy for uterine benign diseases.

OBJECTIVE: This study aimed to review the surgical outcomes and health-related quality of life (HRQOL) of total vaginal (TVH) and single-port total laparoscopic hysterectomy (SP-TLH) for uterine benign diseases. STUDY DESIGN: This study included 121 patients who had undergone TVH or SP-TLH for uterine benign diseases between April 2011 and July 2012. Surgical outcomes, complications, and HRQOL were reviewed in the two groups. Preoperative and postoperative HRQOL data from the 36-item Short Form questionnaire (SF-36) were recorded for all patients. RESULTS: TVH was performed more often for the patients who had fewer previous operations (p = 0.32). In the TVH, there were fewer combined surgical procedures (p < 0.01), shorter operation times (p < 0.01), shorter vaginal stump suture times (p = 0.03) and lower complication rates (p < 0.01) than in SP-TLH. Overall, all SF-36 scales improved after surgery, except for the Social Functioning scale. There was no significant difference in any of the scales between the two groups. CONCLUSIONS: TVH has equivalent effects on HRQOL as SP-TLH. SP-TLH is preferred for the cases with complicated and combined procedures.

Role of SUVmax and GLUT-1 Expression in Determining Tumor Aggressiveness in Patients With Clinical Stage I Endometrioid Endometrial Cancer.

OBJECTIVE: The aim of this study was to determine the role of (18)F-fluorodeoxyglucose positron emission tomography/computed tomography in estimating tumor aggressiveness in patients with clinical stage I endometrial cancer and the correlation between aggressiveness and expression of glucose transporter 1 (GLUT-1). METHODS: F-fluorodeoxyglucose positron emission tomography/computed tomography was performed on 43 patients with clinical stage I endometrioid endometrial cancer. (18)F-fluorodeoxyglucose uptake was quantified by calculating the maximum standardized uptake value (SUV(max)) and GLUT-1 expression status based on immunohistochemistry. RESULTS: The mean (SD) SUV(max) of the primary tumor was 8.55 (5.04). The mean SUV(max) and GLUT-1 expression in stage IB and stage IC were significantly higher than that in stage IA (P = 0.001; P = 0.003). The mean (SD) SUV(max) was 6.81 (4.55) in grade 1, 10.92 (4.61) in grade 2, and 15.35 (1.34) in grade 3 (grade 1 vs grade 2 and 3; P = 0.005). The mean (SD) GLUT-1 expression was 1.17 (0.94) in grade 1, 2.00 (0.94) in grade 2, and 3.00 (0.00) in grade 3 (grade 1 vs grade 2 and 3; P = 0.017). CONCLUSIONS: Tumor aggressiveness, such as myometrial invasion or tumor grade, had a positive correlation with the SUV(max) and GLUT-1 expression in patients with clinical stage I endometrioid endometrial cancer.

Is Laparoscopic Incidental Appendectomy in Gynecological Diseases Related to Postoperative Intraabdominal Infection and Complications?

OBJECTIVE: To establish whether laparoscopic incidental appendectomy in gynecological diseases is related to postoperative intraabdominal infection and complications. STUDY DESIGN: This study was performed prospectively in 443 patients who underwent laparoscopic surgery without appendectomy (n = 222) or with appendectomy (n = 221). On postoperative day 1, drain fluid was cultured in all patients. All data were compared using Student's t test and χ2 test. RESULTS: Bacteria grew in cultures of 93 patients (21.0%): 38 (17.1%) in the nonappendectomy group and 55 (24.9%) in the appendectomy group (p < 0.01). There were statistical differences in the incidence of bacterial growth, postoperative complications, and post-operative laboratory changes for percentage of neutrophils (p < 0.01) and C-reactive protein (p < 0.01). Thirteen genera of bacteria grew in the drain culture. The 9 commensal organisms of the human intestine were identified in all patients, each 8 genera of bacteria in both groups. The surgical type did not affect the postoperative drain culture results. CONCLUSION: Postoperative bacterial growth and complications were increased in the laparoscopic incidental appendectomy group. Infections with bacteria from the intestine in both groups were also related to contamination during surgery and postoperative care.

Unabsorbed polylactide adhesion barrier mimicking recurrence of gynecologic malignant diseases with increased ¹8F-FDG uptake on PET/CT.

PURPOSE: To evaluate the incidence and characteristics of the unabsorbed polylactide adhesion barrier with increased (18)F-fluorodeoxyglucose ((18)F-FDG) uptake after surgeries for gynecologic malignancies. METHODS: Between September 2006 and November 2009, we reviewed the charts of 75 patients who were provided a polylactide adhesion barrier after surgery for gynecologic malignant diseases. We surveyed the cases of increased (18)F-FDG uptake on positron emission tomography/computed tomography (PET/CT), and evaluated the effectiveness of polylactide adhesion barrier using an adhesion scoring system. RESULTS: Ten patients (13.3 %) had a solitary pelvic mass with increased (18)F-FDG uptake in the follow up PET/CT. The characteristics of patients and tumors are described below. The median age was 48 years (range 19-66 years). The median tumor size was 1.9 cm (range 1.0-2.3 cm), and the median SUVmax of the pelvic mass was 5.1 (range 3.7-7.9). The median time between initial operations and second operation was 13.5 months (range 8-23 months). We performed laparoscopic excision of the pelvic mass, and the biopsy revealed foreign body reactions with the exception of 1 case, which contained tumor cells under the unabsorbed polylactide adhesion barrier. The median adhesion grade was 1 (range 0-2). CONCLUSIONS: A solitary pelvic mass found in the PET/CT with increased (18)F-FDG uptake after usage of a polylactide adhesion barrier may be an unabsorbed remnant. The adhesion barrier should be used with caution in patients with gynecologic malignant diseases.

Anatomical variations of the internal iliac veins in the presacral area: Clinical implications during sacral colpopepxy or extended pelvic lymphadenectomy.

The purpose of this study was to classify anatomical variations of the internal iliac vein (IIV) in relation to robotic or laparoscopic extended lymphadenectomy. Between March 2011 and July 2012, 60 consecutive patients underwent robotic or laparoscopic extended lymphadenectomy. We retrospectively reviewed surgical video clips and analyzed the pattern of the IIVs in the presacral area. IIV variations were classified into seven types: Type A, normal (n = 39, 65.0%); Type A with a dilated middle sacral vein (n = 5, 8.3%); Type B, left IIV connecting centrally to the left external iliac vein (n = 5, 8.3%); Type C, a separated trunk of the left IIV draining into the left central common iliac vein (CIV; n = 1, 1.7%); Type D, a separated trunk of the right IIV draining into the left central CIV (n = 8, 13.3%); Type E, a separated trunk of the right IIV draining into the right central CIV (n = 0, 0%); and Type F, separated trunks of the bilateral IIV connecting with each other before draining into the left central CIV (n = 2, 3.3%). The prevalence of IIV anomalies was 26.7%; the incidence of separated IIV trunks was 18.3%. To prevent life-threatening IIV injury during extended lymphadenectomy or sacral colpopexy, the anatomical variations of the IIVs should be known exactly.

Robot-assisted total preservation of the pelvic autonomic nerve with extended systematic lymphadenectomy as part of nerve-sparing radical hysterectomy for cervical cancer.

OBJECTIVE: To evaluate our short-term clinical outcomes of robot-assisted autonomic nerve-sparing extended systematic lymphadenectomy as part of nerve-sparing radical hysterectomy. METHODS: Between March 2011 and June 2012, we observed prospectively 28 consecutive patients who underwent robot-assisted autonomic nerve-sparing extended systematic lymphadenectomy, including the superior and inferior gluteal, presacral (subaortic), common iliac, and lower para-aortic nodes. RESULTS: The predominant International Federation of Gynecology and Obstetrics stage was IB1 (15 patients), followed by IB2 (5 patients), IA2 (3 patients), IIA1 (3 patients), and IIA2 (2 patients). The mean ± SD total operating time was 308.8 ± 54.9 minutes, and the mean ± SD console time was 280.0 ± 46.0 minutes. The mean ± SD blood loss was 102.7 ± 153.8 mL. The mean ± SD acquired pelvic lymph node was 27.1 ± 9.3, the mean ± SD extended lymph node was 19.2 ± 9.6, and the mean ± SD total lymph node was 46.3 ± 14.5. A total of 10 patients (35.7%) had nodal metastasis; among them, 6 patients (21.4%) had single pelvic nodal metastasis, 3 patients (10.7%) had concurrent pelvic and extended nodal metastasis, and one patient (3.6%) had single extended nodal metastasis. No intraoperative complications that required treatment occurred; however, ureterovaginal fistula was identified in 4 patients (14.3%) and ureter stricture in 4 patients (14.3%) after radiotherapy. After a median follow-up of 10 months (range, 1-16 months), there was no pelvic recurrence; however, one patient had recurrence at transposition site of ovary. CONCLUSIONS: With the advantage of delicate movement of robot instrument, robot-assisted systematic extended lymphadenectomy with total preservation of pelvic autonomic nerves did not compromise the radicality, and its surgical technique was feasible and safe. By using this approach, we could harvest more lymph nodes and have a high rate of metastatic nodes without disturbing voiding function; however, there was increased rate of urological complications. Moreover, long-term survival benefit after an extended systematic lymphadenectomy must be evaluated.

Robot versus laparoscopic nerve-sparing radical hysterectomy for cervical cancer: a comparison of the intraoperative and perioperative results of a single surgeon's initial experience.

OBJECTIVE: The aim of the study was to compare the initial surgical outcomes and learning curve of nerve-sparing robotic radical hysterectomy (RRH) with nerve-sparing total laparoscopic radical hysterectomy (TLRH) for the treatment of early-stage cervical cancer in the first 50 cases. METHODS: Between January 2008 and March 2012, 50 consecutive patients underwent nerve-sparing RRH. These patients were compared with a historic cohort of the first 50 consecutive patients who underwent nerve-sparing TLRH. RESULTS: Both groups were similar with respect to patients and tumor characteristics. The mean operating time in the RRH group was significantly longer than that in the TLRH group (230.1 ± 35.8 vs 211.2 ± 46.7 minutes; P = 0.025). The mean blood loss for the robotic group was significantly lower compared with the laparoscopic group (54.9 ± 31.5 vs 201.9 ± 148.4 mL; P < 0.001). There was no significant difference in the mean pelvic lymph nodes between the 2 groups (25.0 ± 9.9 vs 23.1 ± 10.4; P = 0.361). The mean days to normal residual urine were 9.6 ± 6.4 in RRH and 11.0 ± 6.2 in TLRH (P = 0.291). The incidence of intraoperative complication was profoundly lower in RRH compared with that of TLRH (0% vs 8%; P = 0.041). Moreover, no intraoperative transfusion was required in RRH, whereas 4 (8%) were required in TLRH (P = 0.041). In both groups, we found no evidence of a learning effect during the first 50 cases. CONCLUSIONS: During the first 50 cases, surgical outcomes and complication rates of nerve-sparing RRH were found to be comparable to those of nerve-sparing TLRH. Moreover, the mean blood loss and intraoperative complication rate in the robotic group were significantly lower than those in the laparoscopic group. Surgical skills for nerve-sparing TLRH easily and safely translated to nerve-sparing RRH in case of experienced laparoscopic surgeon.

Oncologic results and surgical morbidity of laparoscopic nerve-sparing radical hysterectomy in the treatment of FIGO stage IB cervical cancer: long-term follow-up.

OBJECTIVES: The aim of this study was to evaluate a long-term follow-up data for oncologic results and surgical morbidity of a laparoscopic nerve-sparing radical hysterectomy (NSRH) in the treatment of FIGO stage IB cervical cancer. METHODS: This was a retrospective study that comprised consecutive 125 patients with cervical cancer stage IB1 (n = 105) and IB2 (n = 20) who underwent a laparoscopic NSRH (Piver type III) by a gynecologic oncologist without selecting patients from January 1999 to December 2007. RESULTS: In regression analysis, the operating time (R linear = 0.311, P < 0.001) and estimated blood loss (R linear = 0.261, P < 0.001) were decreased, whereas the number of harvested pelvic lymph nodes (R linear = 0.250, P < 0.001) was increased. Seventeen patients (13.6%, 17/125) were found to have pelvic node metastasis. Para-aortic node metastasis had occurred in 2 patients (5.1%, 2/39). There were high urological complications (13/125, 10.4%) related to radical surgery. Forty-one patients (33%) needed transfusions. Positive surgical margins did not exist. Patients were able to self-void at a mean of 10.3 days postoperatively. The return rates to normal voiding function at postoperative 14 and 21 days were 92.0% and 95.2%, respectively. Thirteen patients (IB1 n = 9, IB2 n = 4) experienced a recurrence postoperatively. Six patients (IB1 n = 3, IB2 n = 3) died of recurrent disease. Five-year disease-free survival rates of cervical cancer IB1 and IB2 were 92% and 78%, respectively (P = 0.1772). Five-year overall survival rates of cervical cancer IB1 and IB2 were 96% and 83%, respectively (P = 0.0437). CONCLUSIONS: A laparoscopic NSRH for FIGO stage IB cervical cancer was comparable to open NSRH in terms of early recovery of bladder function. It did not compromise surgical radicality, but revealed high urological complications, long operating time, and much blood loss, compared with conventional radical hysterectomy. However, these surgical morbidities were corrected with increase in experiences.

Robotic uterine artery preservation and nerve-sparing radical trachelectomy with bilateral pelvic lymphadenectomy in early-stage cervical cancer.

OBJECTIVE: The aim of the study was to evaluate the safety and feasibility of robotic uterine artery preservation and nerve-sparing radical trachelectomy with pelvic lymphadenectomy using the da Vinci surgical system. METHODS: Three patients who were diagnosed with early-stage cervical cancer underwent robotic uterine artery preservation and nerve-sparing radical trachelectomy with bilateral lymphadenectomy from January 2010 to March 2010. The data were compared with those of 4 cases of total laparoscopic nerve-sparing radical trachelectomy that were performed from July 2004 to May 2005 and were previously reported. RESULTS: In the robotic group, the mean console time was 275 minutes (range, 240-305 minutes). The mean postoperative hemoglobin change was 0.4 g/dL (range, 0.2-0.6 g/dL). The mean estimated blood loss was 23 mL (range, 15-40 mL), which is less than that of the laparoscopic group. There were no metastases detected in any of the cases, and the resection margins were negative in both groups. CONCLUSIONS: The robotic uterine artery preservation and nerve-sparing radical trachelectomy with pelvic lymphadenectomy were efficient in reducing blood loss and feasible methods such as other approaches.

A case of uterine pseudoaneurysm combined with gestational trophoblastic disease in a 30-year-old woman.

Uterine artery pseudoaneurysm is a rare disease and it can be diagnosed using conventional doppler ultrasongraphy. Damaged uterine arteries from cesarean section, myomectomy, dilatation & curettage, etc. are known as causes of the disease. Massive bleeding in the rupture can cause fatal result. We observed an increase in ß-hCG and uterine artery pseudoaneurysm a year after the performance of dilatation & curettage for hydatidiform mole and treated it with arterial embolization and chemotherapy. We report the case and give a brief review of the literature.

Laparoscopic second look operation for ovarian cancer: single center experiences.

We compared the clinical outcomes of laparoscopic surgery with those of laparotomy in second-look operations for ovarian cancer. We retrospectively reviewed the medical records of 35 patients treated between January 2000 and December 2005. They were categorized into two groups: Laparoscopy versus laparotomy group. Among 35 patients, 18 patients (51.4%) were treated with laparoscopy, and 17 patients (48.6%) were treated with laparotomy. There were no statistically significant differences except for hospital stay (laparoscopy vs. laparotomy five days vs. nine days, p < 0.05). Eight patients (44.4%) in the laparoscopy group and six (35.3%) in the laparotomy group were found to be pathologically positive after the second look operation. There were two recurrences (20.0%) in the laparoscopy group and four (36.4%) in the laparotomy group pathologically negative in the second-look operation (p = 0.557). There were no differences in disease-free survival rates (p = 0.705) between the two groups. The second look operation is an ideal method for histologic comfirmation of recurrent or persistent ovarian cancer. Laparoscopic surgery seems a safe and accurate method for the second-look examination, and can also reduce patient discomfort, hospital stay and morbidity associated with laparotomy.

Vaginal evisceration after total laparoscopic radical hysterectomy in cervical cancer.

A 50-year-old woman came to the emergency department with vaginal evisceration that occurred 7 months after a total laparoscopic radical hysterectomy. Vaginal evisceration was repaired by a laparoscopic-vaginal approach without a laparotomy. This is the first report of vaginal evisceration after a total laparoscopic radical hysterectomy.

The effect of nonperitonization and laparoscopic lymphadenectomy for minimizing the incidence of lymphocyst formation after radical hysterectomy for cervical cancer.

OBJECTIVES: To determine the clinical effect of nonperitonization and laparoscopic lymphadenectomy using bipolar electrocautery after radical hysterectomy for cervical cancer compared with peritonization and open lymphadenectomy using monopolar electrocautery. MATERIALS AND METHODS: This was a retrospective study of 180 patients who underwent a radical hysterectomy and pelvic lymph node dissection (PLND) for cervical cancer from August 1998 to August 2007. The patients were composed of the Peritonization + Laparotomy group (group A; n = 98, 196 PLND) and the Nonperitonization + Laparoscopy group (group B; n = 82, 164 PLND). Group B left the peritoneum in front of the PLND open. Two closed-suction drains were placed at each side of the PLND. RESULTS: Group B statistically showed a lesser total amount of lymphatic drainage (P = 0.001), shorter duration of inserted drains (P < 0.001), and shorter length of hospital stay (P < 0.001), compared with group A. The formation of lymphocysts occurred in 30 patients (41 lymphocysts) of group A and 5 patients (5 lymphocysts) of group B. Lymphocyst formation of group B had a statistically lower incidence than that of group A (P < 0.001). Lymphocyst formation was associated with an increase in the total amount of lymphatic drainage in group A (P = 0.090) and group B (P = 0.041) and a pathologic type of adenocarcinoma in group B (P = 0.016). Surgical experiences were not correlated with lymphocyst formation. CONCLUSIONS: The omission of peritonization and laparoscopic lymphadenectomy using bipolar electrocautery in early-stage cervical cancer were more effective than peritonization and open lymphadenectomy using monopolar electrocautery in minimizing the incidence of lymphocyst formation.

Immunohistochemical expression of YKL-40 in peritoneal endometriosis.

AIMS: To evaluate the relationship between the immunohistochemical expression of YKL-40 and peritoneal endometriosis by using paraffinized peritoneal tissue blocks. METHODS AND MATERIALS: We retrospectively collected data from 27 patients whose pathologic reports indicated invasion of the peritoneum by endometriosis. A conventional peroxidase staining technique was performed using rabbit polyclonal antibody (Quidel corporation, Santa Clara, CA) on peritoneal tissue blocks; their histology was then reviewed by a pathologist, and data were analyzed by nonparametric and Mann-Whitney tests. RESULTS: YKL-40 was detected immunohistochemically in 17 (63%) of 27 cases. The number of biopsies which were invaded by endometriosis (P = 0.015), with a score based on the revised classification of endometriosis (American Society for Reproductive Medicine) had statistical significance (P = 0.001). The obstetric history, age, body mass index, severity, and occurrence of dysmenorrhea, menstrual phase, preoperative CA 125, erythrocyte sedimentation rate, and white blood cell count had no statistical significance. YKL-40 immunoreactivity was recognized as brown staining, localized to the cytoplasm of epithelial cells of endometrial gland in peritoneal endometriosis. There was no positive staining on endometrial stromal cells or smooth muscle cells. CONCLUSIONS: YKL-40 is related to severity of peritoneal endometriosis. However why a different expression level of immunohistochemical staining should occur is not known and needs further investigation.

Clinical significance of serum albumin level in pregnancy-related hypertension.

AIM: To evaluate the usefulness of serum albumin level as a marker of severity in pregnancy-related hypertension. METHODS: Of 454 patients with pregnancy-related hypertension who were admitted to Kyungpook National University Hospital between May 1999 and April 2008, the medical records and laboratory tests of 354 patients who met the inclusion criteria for the current study were reviewed. A comparison of the characteristics of each hypertension group and the correlation between serum albumin levels and the time to delivery, 24-h urine protein, and/or pregnancy outcomes were statistically analyzed using SPSS 12.0 (SPSS Korea, Korea). RESULTS: Serum albumin level had a negative correlation with 24-h urine protein (Pearson's correlation coefficient = -0.481) and a positive correlation with time to delivery (= 0.389). Serum albumin ≤3.0 g/dL was highly associated with severe proteinuria (>2 g/day). There were significant differences in maternal or perinatal morbidity as a function of serum albumin level. If serum albumin level fell below 2.5 g/dL, the risks of ascites, hemolysis elevated liver enzyme low platelet (HELLP) syndrome and perinatal mortality significantly increased (odds ratio [OR] and 95% confidence interval [CI]: 3.5 [1.5-8.1], 12 [3.1-45], and 6.1 [1.7-22], respectively). CONCLUSION: Serum albumin level in pregnancy-related hypertension is a significant determinant of disease severity and may be considered as a useful marker for predicting time to delivery, severe proteinuria, and pregnancy outcomes.

Laparoscopic pelvic anatomy of nerve-sparing radical hysterectomy.

Many reports regarding nerve-sparing radical hysterectomy have been published. However, most reports have been based on systematic descriptions via laparotomy or cadaver dissection. The aim of this work was to describe the pelvic anatomy of nerve-sparing radical hysterectomy via laparoscopy, with specific focus on the inferior hypogastric plexus. This study is based on 125 patients with FIGO stage IB cervical cancer who had undergone laparoscopic nerve-sparing radical hysterectomies since 1999. The inferior hypogastric plexus was demonstrated via laparoscopy and was comprised of afferent fibers from the sacral root (S2, S3, and S4), sacral sympathetic ganglion, and hypogastric nerve, and efferent fibers forming its vesical, uterovaginal, and rectal branches. During the dissection of the posterior leaf of the vesicouterine ligament, various vesical veins were identified. If the cut edge of an inferior vesical vein was pulled medially with upward traction, the vesical branches of the inferior hypogastric plexus were exposed and these were divided into medial and lateral branches. The magnified view of laparoscopy made it possible to dissect nerves and vessels meticulously and to secure a clear resection margin during the dissection of the deep part of the cardinal ligament, uterosacral ligament, and posterior leaf of the vesicouterine ligament.

Learning curve of laparoscopic radical hysterectomy with pelvic and/or para-aortic lymphadenectomy in the early and locally advanced cervical cancer: comparison of the first 50 and second 50 cases.

BACKGROUND: To compare the surgical and oncological outcomes and morbidity of the first 50 cases treated by laparoscopic radical hysterectomy with those of the second 50 cases. METHODS: Between October 1994 and January 2004, we retrospectively reviewed the charts of 100 consecutive patients (International Federation of Gynecology and Obstetrics stages IA2 [n = 12], IB1 [n = 56], IB2 [n = 15], IIA [n = 15], and IIB [n = 2]) who underwent laparoscopic radical hysterectomy with pelvic and/or para-aortic lymphadenectomy. One hundred patients were divided into the first 50 cases (group 1) and second 50 cases (group 2). RESULTS: Operating time, length of hospital stay, time to normal residual urine, and transfusion rate significantly decreased, and the acquired number of pelvic nodes significantly increased when comparing group 1 with group 2. The intraoperative and postoperative complication rates profoundly decreased in group 2 as compared with group 1. After a median follow-up of 66.5 months, 10 patients had a recurrence, 9 of whom died. The 5-year overall survival rates were 96% in group 1 and 90% in group 2, and 5-year disease-free survival rates were 92% in group 1 and 90% in group 2. CONCLUSIONS: Laparoscopic radical hysterectomy is a feasible and safe treatment modality in early and even locally advanced cervical cancer without decreasing survival. Surgical outcome was improved with experience, and the complication rate related to operation of group 1 was higher than that of group 2. There was no significant difference in survival between the 2 groups.
