Successful pregnancy with in vitro fertilization after vaginal radical trachelectomy and pelvic lymphadenectomy in stage IB1 cervical cancer.

OBJECTIVE: To present a case of successful pregnancy after undergoing vaginal radical trachelectomy (VRT) and pelvic lymph node dissection (PLND) for early-stage cervical cancer. CASE REPORT: A 37-year-old female patient has been diagnosed with stage IB1 cervical cancer and underwent VRT and PLND. Two years after the surgery, the patient successfully conceived and delivered a healthy baby through a cesarean section. CONCLUSION: This case report demonstrates that pregnancy after VRT and PLND for stage IB1 cervical cancer is possible and can result in a successful outcome. This report provides valuable information for patients and physicians who are considering these surgical options.

Emergent cesarean section in a preterm pregnant woman with severe COVID-19 pneumonia in Taiwan: A case report.

OBJECTIVE: The pandemic Coronavirus Disease 2019 (COVID-19) is a global public health crisis. Many maternity units worldwide are currently establishing the management protocols for these patients. CASE REPORT: We report the first critically ill pregnant woman with COVID-19-induced respiratory failure undergoing emergent caesarean delivery at 32 weeks of gestation, in the setting of a positive pressure operating room (OR) with negative pressure anteroom in Taiwan. CONCLUSION: Multidisciplinary planning and collaboration are necessary to achieve satisfactory clinical outcomes in pregnancies with critical COVID-19 pneumonia. The combinations of comprehensive evaluation, timely treatment as well as establishment of rigorous protocol and safe environment for the emergent delivery are important.

Laparoendoscopic two-site myomectomy (LETS-M) using conventional laparoscopic instruments and the glove-port technique.

PURPOSE: To evaluate the perioperative outcome of laparoendoscopic two-site myomectomy (LETS-M). METHODS: The medical records of 204 women receiving LETS-M in a tertiary referral center, including 183 surgeries performed by the experienced surgeon and 21 surgeries performed by 3 well-supervised trainees were retrospectively reviewed. RESULTS: The age of the participants was 39.3 ± 6.4 years. The mean diameter of the largest myoma and the mean number of myomas were 8.5 ± 2.2 cm and 1.7 ± 1.1, respectively. Thirty-one (15%) operations removed more than 2 myomas larger than 5 cm in diameter. The mean weight of the myomas was 281.1 ± 183.1 g. The operation time was 97.6 ± 40.2 min, and the intraoperative blood loss was 99.3 ± 115.2 mL. There were 3 (1%) cases of excessive blood loss (more than 500 mL) and 2 (1%) of postoperative hematoma. The only significant difference between the experienced surgeon and trainees was the operation time (92.3 ± 32.2 min vs. 141.2 ± 54 min, p < .001), while the myoma number, myoma diameter, myoma weight, and intraoperative blood loss were not significantly different. The operation time did not differ among different myoma locations. In multivariate analysis, virginity, myoma number, more than 2 large myomas, and myoma size were independent variables for longer operation times. No patient experienced any major complications. CONCLUSION: LETS-M using conventional laparoscopic equipment is a minimally invasive surgical method that is safe, effective, and easy to learn for managing uterine myoma. It is useful to achieve a favorable perioperative outcome with acceptable operation time.

Effect of Early Supplemental Formula Intervention on Body Weight and Hyperbilirubinemia in Neonates During 72 h After Birth.

Background: The full breastfeeding may lead to insufficient milk intake of newborns and increase the rate of body weight loss (BWL). Severe BWL was generally believed as a cause of significant hyperbilirubinemia in newborn babies. The study aimed to investigate the effect if early supplemental feeding in newborns with birth weight loss at the first 3 days after birth could decrease the rate of hyperbilirubinemia 72 h of birth. Methods: A total of 395 neonates with gestational age >37 weeks and birth body weight >2500g were prospectively collected between 2016 and 2018. We analyzed 280 neonates with BWL rate reaching the predictive value (4.5%, 7.5%, and 8% on the first, second, third day after birth, respectively) for subsequent hyperbilirubinemia after 72 hours after birth. The enrolled cases were divided into four subgroups as interventional consecutive milk supplement for 0, 1, 2, and 3 days after birth for further analysis Results: For newborns with BWL reaching the predictive value on the first day after birth, the serum bilirubin levels were lower in the experimental group than those in the non-involved control group (p < 0.05). For newborns with three consecutive days of interventional milk supplementation, the serum bilirubin levels at the 72 h after birth showed the lowest levels compared with the other sub-groups with two consecutive days and one consecutive day of interventional milk supplementation (p < 0.05). Moreover, there was a significantly decreasing trend in the consecutive days of interventional milk supplementation (p < 0.05). Conclusion: Newborns with BWL over 4.5% on the first day after birth receiving early intervention milk supplementation could significantly reduce serum bilirubin levels at the 72 h after birth. The more days of consecutive milk supplementation after birth may lead to the lower the 72 h serum bilirubin levels. It is recommended to early and consecutive milk supplementation after birth to be an effective way in reducing serum bilirubin levels.

Comparison of uterine scarring between robot-assisted laparoscopic myomectomy and conventional laparoscopic myomectomy.

This study compared uterine wound healing after robot-assisted laparoscopic myomectomy (RM) and laparoscopic myomectomy (LM). Ultrasound was used to evaluate the scar repair of uterine wounds at 1, 3, and 6 months postoperatively. Ninety-three RM and 110 LM patients were enrolled. More myomas excised using RM were type 1∼type 3(51.1%) and more myomas excised using LM were type 4∼type 6(54.2%), p < .001. Both groups had myomas of similar size (RM vs. LM, 9.0 vs. 8.4 cm, p = .115) and weight (RM vs. LM, 322 vs. 274 g, p = .102). The mean myoma number was significantly larger in RM patients than LM patients (RM vs. LM, 3.3 vs. 1.8, p < .001). Significantly more patients were found to have haematomas in the LM than the RM group (RM vs. LM, 0 vs. 6, p = .032); two in type 3, two in type 4 and two in type 8 myomas. Four small haematomas spontaneously resolved at the 3rd month, and a large one resolved at the 9th month postoperatively. One haematoma caused pelvic infection and a 7-cm peritoneal inclusion cyst during sonographic follow up. RM resulted in fewer postoperative haematomas and may result in superior uterine repair relative to LM after excision of symptomatic type 3, type 4 and type 8 myomas. RM is suggested for these patients, especially those considering future pregnancy.IMPACT STATEMENTWhat is already known on this subject? Reconstructive suturing and uterine wound healing are the main challenges when performing laparoscopic myomectomy (LM), and spontaneous uterine rupture during pregnancy following LM has been reported because of its limitations in multilayer closure of the myoma bed. Robot-assisted laparoscopic myomectomy (RM) has improved visualisation and EndoWrist movements resulted in adequate multilayered suturing, which may overcome the technical limitations of reconstructive suturing in conventional LM.What do the results of this study add? We evaluated postoperative uterine scarring after RM and LM using ultrasound and found RM resulted in fewer postoperative haematomas, which result in superior uterine wound repair, relative to LM after excision of symptomatic type 3, type 4 and type 8 myomas.What are the implications of these findings for clinical practice and/or further research? RM is suggested for symptomatic type 3, type 4 and type 8 myomas because of superior uterine wound repair, especially those considering future pregnancy.

Anti-NMDAR encephalitis with ovarian teratomas: Review of the literature and two case reports.

OBJECTIVE: Anti-N-methyl-d-aspartate receptor (anti-NMDAR) encephalitis is a paraneoplastic syndrome associated with ovarian teratomas. Anti-NMDAR encephalitis patients typically present with prominent psychiatric symptoms, seizures, and involuntary movements; further, they rapidly progress to unresponsiveness with central hypoventilation and dysautonomia. CASE REPORT: This paper presents two anti-NMDAR encephalitis cases with ovarian teratomas and reviews 13 anti-NMDAR encephalitis clinical case reports in Taiwan, of which six involved ovarian tumors, five being mature teratomas. Patients presented with acute onset of psychiatric symptoms and subsequently developed coma within a few days. Anti-NMDAR encephalitis usually occurs in young women and is often associated with ovarian tumors, specifically teratomas. Ovarian cystectomy or oophorectomy was performed, which markedly improved cognitive function. CONCLUSION: Paraneoplastic neurological conditions associated with ovarian teratomas represent a fascinating disease process. Identifying the gynecological cause of a neurological condition, particularly in young women, followed by prompt treatment can remarkably improve clinical conditions and, thus, be lifesaving.

Epithelial-Mesenchymal Transition with Malignant Transformation Leading Multiple Metastasis from Disseminated Peritoneal Leiomyomatosis.

Disseminated peritoneal leiomyomatosis (DPL) is a rare condition that is characterized by the presence of multiple subperitoneal or peritoneal smooth muscle nodules of varying sizes on the omentum and peritoneal surfaces, grossly mimicking disseminated carcinoma. DPL usually develops in premenopausal women with a benign course, and it is often found incidentally during abdominal surgery. Malignant transformation is a rare clinical course of DPL. Only a few studies have focused on DPL transformation into a leiomyosarcoma. Herein, we describe the case of a 61-year-old woman with a history of recurrent leiomyoma of the uterus who presented with intermittent progressive abdominal pain. The imaging study revealed a huge heterogeneous density mass in the pelvic region with pulmonary and hepatic metastases. Exploratory laparotomy and debulking surgery were performed, and showed the coexistence of DPL and leiomyosarcoma. She died approximately one month after the diagnosis because of rapid progression of pleural effusion due to malignancy. This case highlights the clinical features of DPL and its malignant transformation and metastasis so physicians can make an early diagnosis and provide timely management.

Uncommon cause of voiding dysfunction in a female patient-vaginal abscess: A case report.

BACKGROUND: Vaginal abscess is a treatable disease and should be considered in female patients with voiding difficulties and perineal tenderness. There are no reported cases of vaginal abscess causing voiding dysfunction in the absence of a previous surgery. Early diagnosis and drainage of vaginal abscesses may lead to excellent outcomes. CASE SUMMARY: We presented a case of vaginal abscess that caused voiding dysfunction without surgery history. A 64-year-old woman had a past history of type 2 diabetes mellitus. She came to our clinic following urinary difficulty with perineal tenderness. Bladder ultrasonography revealed a pelvic cystic lesion with a mass effect on the bladder. The presence of a vaginal abscess was suspected following pelvic examination and transvaginal ultrasound. After transvaginal drainage of the vaginal abscess and a full course of antibiotic treatment, she recovered well without any urination symptoms. CONCLUSION: Voiding dysfunction caused by vaginal abscess is rare but should be considered in female patients with perineal tenderness.

Laparoendoscopic single-site myomectomy using conventional laparoscopic instruments and glove port technique: Four years experience in 109 cases.

OBJECTIVE: To report a single surgeon's experience with 109 laparoendoscopic single-site myomectomy (LESS-M) using conventional laparoscopic instruments and a homemade glove port system. MATERIALS AND METHODS: A total of 109 consecutive women who underwent LESS-M between March 2011 and April 2015 were reviewed. RESULTS: The mean age and body mass index were 38.3 ± 6.5 years and 22.1 ± 3.0 kg/m2. The mean diameter of the largest myoma and the mean number of myomas were 8.1 ± 2.4 cm and 1.6 ± 0.7. The mean weight of the myomas was 223.2 ± 159.7 g. The most common type of myoma was intramural (61%), followed by subserosal (23%), submucosal (9%), and intraligamental (7%). The most common site of the myomas was anterior (39%), followed by posterior (38%), lateral (15%), and fundal (9%). The mean operative time and estimated blood loss were 138.5 ± 43.8 min and 104.9 ± 270.1 mL. Two patients (1.8%) required intraoperative transfusion. The mean hospital stay was 2.5 ± 0.6days. There were no conversions to laparotomy, but three patients(2.8%) were converted to two-port laparoscopic myomectomy. No patient experienced any major complication, including bowel, ureter, bladder injuries, or incisional hernia. Six women became pregnant after the operation, and five of these patients delivered their babies at full term by cesarean section. One patient delivered her baby at a gestational age at 32 weeks due to idiopathic polyhydramnios by cesarean section. One patient had the second pregnancy and delivery after LESS-M. Fourteen patients (12.8%) had small recurrent myomas that did not require treatment. CONCLUSION: LESS-M is a feasible alternative for patients with symptomatic myomas, and this technique can provide cosmetic advantages compared to conventional laparoscopic surgery.

Radical trachelectomy for early stage cervical cancer: A case series and literature review.

OBJECTIVE: Radical trachelectomy (RT) is an alternative treatment for preserving fertility in patients with cervical cancer. Because women with operable cervical cancer opting for fertility preservation are scarce, few cases have been reported in Taiwan. Here we report our cases series. MATERIALS AND METHODS: We retrospectively evaluated seven patients who underwent vaginal RT and three patients who underwent abdominal RT in a single medical institute for a median follow-up period of 5 years. RESULTS: The oncological outcome was highly satisfactory. All patients survived and are currently disease-free, except for two who had recurrence and received additional concurrent chemoradiation therapy. Other complications included urinary tract infection, cervical stenosis, and unilateral hydronephrosis. All complications were manageable with little long-term effects. However, no pregnancy was observed during the 5-year follow-up period. CONCLUSION: RT is considered a complicated surgical procedure among gynecological operations. Here we review the literature and describe several factors associated with higher pregnancy rates.

Intraligamental Myomectomy Strategy Using Laparoscopy.

UNLABELLED: STUDY OBJECTIVE: Intraligamental myomas (IMs) represent 6% to 10% of all uterine myomas. An IM growing from the lateral uterine wall into the broad ligament often presents as a large pelvic mass without symptoms. Removing a large IM can be difficult because of the limited operative field and poses challenges during conventional laparoscopic surgical approaches. The risk of injury to the ureter and uterine artery during myomectomy is greater than that during other types of myoma. DESIGN: Retrospective study (Canadian Task Force classification III). SETTING: University-affiliated hospital. PATIENTS: IM was classified into 3 types according to the location: (1) anterior intraligamental myoma (AIM), (2) posterior intraligamental myoma (PIM), and (3) lateral intraligamental myoma (LIM). From April 2007 to July 2015, 83 consecutive patients with IM underwent laparoscopic myomectomy at National Taiwan University Hospital, Taipei, Taiwan, including 23 AIM, 27 PIM, and 33 LIM. INTERVENTIONS: Several techniques are described, and videos are supplied for performing laparoscopic myomectomy safely and easily in different types of IM. MEASUREMENTS AND MAIN RESULTS: Urinary frequency (31%) and a palpable abdominal mass (31%) were the 2 most common presenting symptoms. Most of the lesions were 33 LIM (40%) followed by 27 PIM (32%) and 23 AIM (28%). The mean myoma sizes were 11.0, 8.0, and 7.8 cm; the mean myoma weights were 478, 279, and 309 g; the mean operative times were 134, 108, and 104 minutes; and the mean blood loss during surgery was 224, 94, and 107 mL for LIM, PIM, and AIM, respectively. LIMs had relatively more blood loss because they were heavier and commonly rested alongside the uterine artery. The only complication was late postoperative hemorrhage in 1 case of LIM. Histopathology showed leiomyoma in all cases. Three patients were spontaneously conceived after myomectomy, and each had a successful pregnancy and cesarean delivery. CONCLUSION: Surgical treatment of IM is empirically difficult. It is important to use an approach that considers the location, size, and shape of the myoma. All types of IM presented with similar symptoms, and the highest blood loss occurred during laparoscopic myomectomy of a LIM.

Cepharanthine alleviates liver injury in a rodent model of limb ischemia-reperfusion.

OBJECTIVES: Limb ischemia-reperfusion (I/R) causes remote organ injury (e.g., liver injury). Oxidation and inflammation are crucial mechanisms. We investigated the effects of cepharanthine, a potent antioxidative and anti-inflammatory drug, on alleviating liver injury induced by limb I/R. METHODS: Twenty-four adult male Sprague-Dawley rats were randomized to receive sham operation (Sham), Sham plus cepharanthine, I/R, or I/R plus cepharanthine and designated as the Sham, Sham+Cep, I/R, or I/R+Cep group, respectively (n = 6 in each group). I/R was induced by applying rubber band tourniquets high around each hind limb for 3 hours followed by reperfusion for 24 hours. RESULTS: The plasma levels of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) of the Sham and Sham+Cep groups were low, and the levels of AST and ALT of the I/R group were significantly higher than those of the Sham group (both p<0.001). By contrast, the AST and ALT of the I/R+Cep group were significantly lower than those of the I/R group (both p<0.001). The hepatic levels of nitric oxide (NO), malondialdehyde (MDA), macrophage inflammatory protein 2 (MIP-2), interleukin-6 (IL-6), and cyclooxygenase-2 (COX-2)/prostaglandin E2 (PGE2) of the Sham and Sham+Cep groups were also low. As expected, the NO, MDA, MIP-2, IL-6, and COX-2/PGE2 of the I/R group were significantly higher than those of the Sham group (all p<0.001). By contrast, the NO, MDA, MIP-2, IL-6, and COX-2/PGE2 of the I/R+Cep group were significantly lower than those of the I/R group (all p<0.05). CONCLUSION: Cepharanthine alleviates liver injury in a rodent model of limb I/R. The mechanisms may involve reducing oxidation and inflammation.

Regulatory T Cells Suppress Natural Killer Cell Immunity in Patients With Human Cervical Carcinoma.

OBJECTIVE: To determine the functional attributes of CD4 CD25 regulatory T (Treg) cells by suppressing natural killer (NK) cell activity in human cervical cancer (CC). METHODS: Triple-color flow cytometry was used to study the phenotypic expression of CD4 CD25 Treg cells and NK cells in the peripheral blood lymphocytes (PBLs) and tumor-infiltrating lymphocytes (TILs). In vitro coculture assays were performed to illustrate the cytokine immunoregulations between Treg cells and NK cells. RESULTS: Significantly lower expression ratio of NK cells and higher expression ratio of Treg cells in TILs than PBLs were found. The NK cells displayed significantly higher expression ratio of inhibitory NK receptors (CD158a, CD158b, and NKG2A) and lower expression ratio of activating NK receptors (NKG2D, NKp46, and NKp30) as well as perforin in TILs than PBLs, suggesting the suppressed cytotoxicity of the NK cells in the CC tumor milieu. The expression ratio of transforming growth factor-ß1 (TGF-ß1) on Treg cells as well as TGF-ßRII on Treg cells and NK cells was significantly higher in TILs than PBLs. Further functional in vitro assays demonstrated that NK cell function was suppressed by Treg cells, mimicking the inhibition of TGF-ß on NK cells, and interleukin-2/interleukin-15 stimulation was able to restore the NK cell activity. CONCLUSIONS: These findings indicate that Treg cells in TILs may abrogate NK cell cytotoxicity through TGF-ß pathway, and therefore, Treg cell elimination may enhance NK cell activity and be a novel therapeutic strategy for CC.

Comparison of Laparoscopic Myomectomy in Large Myomas With and Without Leuprolide Acetate.

STUDY OBJECTIVE: To evaluate the efficacy of gonadotropin-releasing hormone analogue (GnRHa) use before laparoscopic myomectomy (LM) in large myomas. DESIGN: Prospective study (Canadian Task Force classification II-1). SETTING: University-affiliated hospital. PATIENTS: Ninety-one women with large myomas (≥10 cm) or more than 2 myomas ≥ 5 cm underwent LM between July 2011 and March 2014. INTERVENTIONS: Forty patients underwent LM after GnRHa use (group A) and 51 underwent LM only (group B). GnRHa was used for 3 doses every 4 weeks before LM in group A. MEASUREMENTS AND MAIN RESULTS: Group A had a significantly smaller maximum diameter of the largest myoma than group B (8.5 ± 2.1 vs 10.7 ± 2.4, p < .001) and fewer patients with myomas larger than 10 cm after GnRHa administration (33% vs 67%, p = .001). In group A, there was a decrease in 2 or more myomas ≥ 5 cm (20% vs 50%) after GnRHa use. Group A also had significantly smaller mean myoma weight (448 vs 567 g, p = .045) and significantly shorter mean operative time (129 ± 30 vs 152 ± 34 minutes, p = .001). Most patients in group A (40%) had an operative time < 119 minutes, whereas most patients in group B (37%) had an operative time between 150 and 179 minutes. Group A also had less intraoperative blood loss (84 ± 53 vs 137 ± 166 mL, p < .001), drop in hemoglobin (1.5 ± 0.8 vs 3.0 ± 1.7 g/dl, p < .001), excessive bleeding (5% vs 33%, p = .001), postoperative hematoma (2.5% vs 9.8%, p = .168), and blood transfusion (7.5% vs 35%, p = .001). CONCLUSION: GnRHa before LM in large myomas may be an effective adjuvant treatment for women with large and multiple myomas. This method is beneficial in decreasing operative time, intraoperative bleeding, postoperative hemorrhage, and need of blood transfusion.

Iatrogenic parasitic myoma: a case report and review of the literature.

OBJECTIVE: To investigate the possible causes of iatrogenic parasitic myoma and methods to prevent its occurrence. CASE REPORT: A 27-year-old nulliparous unmarried patient underwent laparoscopic myomectomy with morcellation for a submucosal myoma at the National Taiwan University Hospital (Taipei, Taiwan). Seven years later, an asymptomatic pelvic tumor was noted during a regular annual follow up. Two pelvic tumors were detected and excised by laparoscopic surgery. The masses were confirmed by histopathology to be cellular leiomyomas. CONCLUSION: In the past 7 years, the incidence of iatrogenic parasitic myomas has increased because of the increased use of minimally invasive surgery using a morcellator. Forty-one cases of iatrogenic parasitic myoma were reviewed from 23 published studies. Parasitic myoma frequently occurs in the dependent part of the abdominal cavity, which suggests seeding of myometrial tissues during morcellation. In situ morcellation and vigorous irrigation with concomitant changes in position may decrease the incidence of retained myoma tissue in the abdomen during surgery.

Comparison of laparoscopic myomectomy using in situ morcellation with and without uterine artery ligation for treatment of symptomatic myomas.

STUDY OBJECTIVE: To evaluate the efficacy of laparoscopic uterine artery ligation (LUAL) before in situ morcellation (ISM) compared with ISM alone. DESIGN: Prospective study (Canadian Task Force classification II-1). SETTING: University-affiliated hospital. PATIENTS: One hundred forty-four women with symptomatic uterine myomas, of whom 45 underwent LUAL and ISM and 99 underwent ISM only, from August 2007 through August 2009. INTERVENTIONS: Ligation or no ligation of the uterine arteries before ISM. MEASUREMENTS AND MAIN RESULTS: In the LUAL+ISM group compared with the ISM group, mean (SD) operative time was significantly longer (107 [34] minutes vs 93 [35] minutes; p = .03), and there was less intraoperative blood loss (84 [53] mL vs 137 [166] mL; p < .001). Eight patients in the ISM group (8.1%) required a blood transfusion, including 4 (4.0%) with excessive intraoperative bleeding and 4 (4.0%) with postoperative hematomas. Although myomas in the LUAL+ISM group weighed more (p < .001), none of the patients in that group had excessive intraoperative bleeding, postoperative hematomas, or required blood transfusion (p = .046). At 2 years of follow-up, in the LUAL+ISM group compared with the ISM group, the myoma recurrence rate was 7% vs 24%, and symptom improvement was reported by 98% of patients vs 86% (statistically significant). CONCLUSION: Laparoscopic myomectomy using an ISM technique with or without simultaneous LUAL may be used in the management of symptomatic uterine myomas; however, LUAL+ISM may result in a better surgical outcome.

Activation of regulatory T cells instigates functional down-regulation of cytotoxic T lymphocytes in human breast cancer.

Regulatory T (Treg) cells are a subpopulation of T cells with the ability to control the responses of both CD4+ and CD8+ T cells. A case-control study was conducted in order to determine the functional attributes of Treg cells within the breast cancer milieu. Triple-color flow cytometry was utilized to study the phenotype expression of CD4+CD25+ Treg cells and CD8+ T cells in autologous tumor-infiltrating lymphocytes (TILs) and peripheral blood lymphocytes (PBLs) derived from 33 patients with stage I-III breast cancer. The prevalence of CD4+CD25+ T cells was significantly higher in TILs than in PBLs. The expressions of FOXP3 and GITR in CD4+CD25+ Treg cells were lower in PBLs than in TILs. Functional studies showed that both granzyme B and perforin were barely expressed in peripheral Treg cells but were highly expressed in Treg cells in the tumor microenvironment. On the contrary, down-regulation of both granzyme B and perforin expressed in the CD8+ cytotoxic T lymphocytes was significantly lower in TILs than in PBLs. Further functional assays demonstrated that Th1 cytokines and cytotoxic molecules were synchronously up-regulated in CD8+ cytotoxic T cells. The in vitro kinetic study showed that adequate activation of TILs derived from breast cancer tissue could restore the appropriate antitumor immune response.

Operating time and blood loss during laparoscopic-assisted vaginal hysterectomy with in situ morcellation.

OBJECTIVE: To develop a regression-based prediction equation for operative time and estimated blood loss in laparoscopically assisted vaginal hysterectomy (LAVH) for large uteri, as required, by combined laparoscopic in situ and vaginal morcellation. DESIGN: Prospective study (Canadian Task Force classification II-1). SETTING: University-affiliated hospitals. SAMPLE: Fifty-six patients who underwent LAVH. Methods. Evaluation of all patients who had LAVH with laparoscopic in situ morcellation and vaginal morcellation during a 2-year period. MAIN OUTCOME MEASURES: Operative time, estimated blood loss, total uterine weight by laparoscopic or vaginal morcellation, complications and length of hospital stay. RESULTS: Mean operative time was 133 ± 22 minutes, and mean blood loss 133 ± 101 ml. Mean uterine weight was 383 ± 187 g by laparoscopic and 251 ± 103 g by vaginal morcellation. Greater total uterine weight and morcellation were associated with longer operative times. Blood loss correlated with uterine weight when vaginal morcellation was also used. A regression equation is presented for estimating the likely operating time and blood loss. CONCLUSIONS: An increase in the operative time and a higher blood loss can be expected as the uterine weight increases and can be predicted taking morcellation methods into account.

Simultaneous laparoscopic uterine artery ligation and laparoscopic myomectomy for symptomatic uterine myomas with and without in situ morcellation.

BACKGROUND: To determine the optimal surgical approach for laparoscopic uterine artery ligation (LUAL) combined with myomectomy in the management of women with symptomatic uterine fibroids. METHODS: This is a prospective study. One hundred and six women with symptomatic uterine myomas underwent LUAL + laparoscopic morcellation after enucleation (enucleation group) (n = 51) or LUAL + laparoscopic in situ morcellation (ISM group) (n = 55). The outcome was measured by comparing surgical techniques, symptom control, recurrence and pregnancy during a 3-year follow-up in both groups. RESULTS: General characteristics of the patients were similar in both groups, except the myomas were larger in the ISM group. The operative time (mean ± SD) was significantly shorter in the ISM group than the enucleation group (107 ± 30 min versus 128 ± 49 min, P = 0.009). There were no differences in the therapeutic outcomes of the two groups at the 3-year follow-up, with low recurrence rates and good symptom control rates. Of the sexually active patients without contraception, the pregnancy and live birth rates were 87.5 and 100% in the ISM group and 66.7 and 83.3% in the enucleation group (all NS). CONCLUSIONS: The LUAL + myomectomy, either by enucleation or ISM, is acceptable in the management of symptomatic uterine fibroids. However, the LUAL + ISM technique might be more feasible, as it requires less operative time.

An easy new approach to the laparoscopic treatment of large adnexal cysts.

We describe a technique for laparoscopically assisted extracorporeal cystectomy or adnexectomy of large adnexal cysts without spillage of the cyst contents. At open laparoscopy, a suction tube decompressed the adnexal cyst from the 2-cm umbilical incision and the puncture hole was closed by the purse string tie, which was followed by extra-corporeal excision of the cyst. With this method, we prevent cyst spillage in three ways. Firstly, the cyst is aspirated extracorporeally. Secondly, when the cyst is totally collapsed, the puncture point is closed with a 1-o Vicryl purse suture and pulled to the umbilicus. Thirdly, as soon as a part of the mass is delivered from the abdomen, it is lined with moist gauze. This method provides excellent visualization and control of the penetration site during aspiration, and minimizes the chances of the cyst contents leaking into the peritoneal cavity. This method was successfully used with 12 patients, including four cystadenomas, one serous cystadenoma, three dermoid cysts (with one pregnant woman who successfully spontaneously delivered a normal baby at term), two low malignant potential ovarian tumors and one grade I endometrioid adenocarcinoma. The cancer patient has shown no recurrence after a follow-up of three years.
