Primary flap closure of perineal defects to avoid empty pelvis syndrome after pelvic exenteration in gynecologic malignancies: An old question to explore a new answer

Pelvic exenteration (PE) is a radical oncological surgical procedure proposed in patients with recurrent or persistent gynecological cancers. The radical alteration of pelvic anatomy and of pelvic floor integrity can cause major postoperative complications. Fortunately, PE can be combined with reconstructive procedures to decrease complications and functional and support problems of pelvic floor, reducing morbility and mortality and increasing quality of life. Many options for reconstructive surgery have been described, especially a wide spectrum of surgical flaps. Different selection criteria have been proposed to select patients for primary perineal defect flap closure without achieving any strict indication of the best option. The aim of this review is to focus on technical aspects and the advantages and disadvantages of each technique, providing an overview of those most frequently used for the treatment of pelvic floor defects after PE. Flaps based on the deep inferior epigastric artery, especially vertical rectus abdominis musculocutaneous (VRAM) flaps, and gracilis flaps, based on the gracilis muscle, are the most common reconstructive techniques used for pelvic floor and vaginal reconstruction. In our opinion, reconstructive surgery may be considered in case of total PE or type II/III PE and in patients submitted to prior pelvic irradiation. VRAM could be used to close extended defects at the time of PE, while gracilis flaps can be used in case of VRAM complications. Fortunately, numerous choices for reconstructive surgery have been devised. As these techniques continue to evolve, it is advisable to adopt an integrated, multi-disciplinary approach within a tertiary medical center.

Influence of uterine manipulator on oncological outcome in minimally invasive surgery of endometrial cancer: A systematic review and meta-analysis

AIM

The endoscopic approach for early-stage endometrial cancer (EC) treatment is considered gold standard. Some authors expressed their concern regarding uterine manipulator (UM) as a risk factor for tumor spillage and dissemination allowing peritoneal or lympho-vascular spaces invasion (LVSI). This meta-analysis aimed to evaluate the effect of UM on the presence of LVSI, recurrence rate and presence of atypical or malignant peritoneal cytology in patients with endometrial cancer.

METHODS

We searched electronic databases including PubMed, MEDLINE, Embase, Scopus, EBSCO, Google Scholar, and ClinicalTrials.gov. The pooled results were used to evaluate the association between the use of UM and oncological outcomes. This systematic review was reported according to PRISMA statement 2020. Statistical meta-analysis was performed using Review Manager software.

RESULTS

This systematic review included 18 studies (3 prospective studies, 13 retrospective studies, and 2 RCT). The pooled results showed no significant difference (RR: 0.86, 95% CI, 0.69 to 1.08) in the incidence of LVSI between manipulated hysterectomy and total abdominal hysterectomy (TAH) and between UM group and non-UM group in minimally invasive surgery (RR: 1.18, 95% CI, 0.76 to 1.85), no significant difference in the rate of recurrence (RR: 1.11, 95% CI, 0.71 to 1.74), in the incidence of positive peritoneal cytology between manipulated and non-manipulated hysterectomies in minimally invasive surgery (RR: 1.89, 95% CI, 0.74 to 4.83) and before and after the use of uterine manipulator (RR: 1.21, 95% CI, 0.68 to 2.16). We found a positive association between malignant cytology and hysterectomies in which a uterine manipulator had been used in a sub-group analysis where LH/LAVH were compared to TAH. (RR = 2.26, 95% CI, 1.08-4.71. P = 0.03).

CONCLUSIONS

This meta-analysis supports that the use of uterine manipulator for minimally invasive treatment of endometrial cancer does not increase the rate of recurrence and LVSI. Therefore, the opportunity of any other studies on its use in endometrial cancer women should be questioned.

Surgical outcomes of diaphragmatic resection during cytoreductive surgery for advanced gynecological ovarian neoplasia: A randomized single center clinical trial - DRAGON

INTRODUCTION

Ovarian cancer (OC) represent nearly 4% of gynecologic malignancies and it is often diagnosed at advanced stage. Diaphragmatic surgery, a fundamental step of advanced stage ovarian cancer (ASOC) debulking surgery, is associated with a high post-operative complication incidence, which is supposedly reduced with thoracostomy tube placement. We assessed the role of intra-operative thoracostomy tube placement, as a prevention measure for post-operative complications, after diaphragmatic resection.

METHODS

This was a single center prospective randomized trial. Ovarian cancer patients, who underwent mono-lateral diaphragmatic resection, were randomized 1:1 into two arms. Arm A included patients receiving intra-operative thoracostomy tube placement (TP); Arm B patients did not receive thoracostomy tube placement (NTP). After surgery, all patients underwent seriate chest x-ray and ultrasound to record thoracic complications. Statistical analysis included uni- and multivariable logistic regression model (proportional odds model).

RESULTS

Three hundred seventy-one patients were screened and 88 patients were enrolled: 44 in arm A and B, respectively. No statistically significant differences for intra-operative (p = 0.291) and any grade of post-operative complication (p = 0.072) were detected, while 6.8% of patients in arm A and 22.7% in arm B experienced severe respiratory symptoms (p = 0.035); 18.2% of patients in arm A had a moderate/large pleural effusion versus 65.9% in arm B (p < 0.0001). At multivariable analysis, results confirmed that the NTP-group had a higher risk to receive post-operative thoracostomy tube placement due to pleural effusion than the TP-group (odds ratio [95% Confidence Interval] = 14.5 [3.7-57.4]).

CONCLUSIONS

Thoracostomy intra-operative tube placement after diaphragmatic resection is effective to prevent post-operative thoracic complications. The extension of resection does not influence outcomes and the risk of post-operative thoracentesis or TP remain elevated.

Pharmacological and non-pharmacological pain relief for office hysteroscopy: an up-to-date review

In-office hysteroscopy is considered the standard technique for visualization of the uterine cavity and the diagnosis of intrauterine pathologies. Moreover, nowadays, it is possible to treat a vast number of intracavitary diseases in the office, without the need for the inpatient setting. However, in some cases, pain might occur, and this is the most common reason for not completing the procedure. Over the last 20 years, many efforts have been carried out to miniaturize the instrumentation and to improve the techniques in order to avoid discomfort. Nonetheless, hysteroscopy still provokes distress for many patients. For this reason, pharmacological and non-pharmacological treatments for intraoperative and postoperative pain relief have been widely used for in-office hysteroscopy, with different results in various groups of women. The purpose of this review was to analyze the current literature on pharmacological aids (non-steroidal anti inflammatory drugs, cyclooxygenase-2 inhibitors, antispasmodics, local anesthetics, prostaglandins, opioids) and non-pharmacological interventions (transcutaneous electrical nerve stimulation, uterine stretching, uterine pressure, warming of distension medium, hypnosis, music, vocal-local) and to evaluate their impact on the relief from pain experienced during in-office hysteroscopy.

Laparoscopic vs percutaneous hysterectomy in obese patients: a prospective evaluation

BACKGROUND

Treatment of obese female patients represents a real challenge. Indeed, obesity among women has reached epidemic levels not only elevating the cardiovascular and endocrinological risks, but also increasing the incidence of various gynecological pathologies (e.g. endometrial cancer and hyperplasia, uterine fibroids, genital prolapse) which commonly require hysterectomy as a surgical solution. In the last decade, minimally invasive surgery has emerged as an approach reducing the invasiveness of the standard laparoscopic surgical procedures while maintaining efficacy and feasibility. As such, in this study we aimed to evaluate the feasibility of percutaneous hysterectomy (PSS-H) approach in obese patients by reporting the first prospective comparison between the PSS-H to laparoscopic hysterectomy (LPS-H).

METHODS

In this multicentric comparative prospective study, 45 patients affected by benign and malignant gynecological conditions were considered eligible for minimally invasive surgery (MIS). Fifteen patients received PSS-H and 30 LPS-H. All patients enrolled received a total hysterectomy ± bilateral salpingo-oophorectomy, with or without lymph nodal staging.

RESULTS

No statistically significant differences were noted in operative time and estimated blood loss between the two groups. Four patients in PSS-H group and 3 in LPS-H group received lymph node staging. A multifunctional energy device was used in all PSS-H and 73.3% of LPS-H procedures (p=0.038). There were no conversions to laparotomy in either group and similarly there were no conversions to conventional laparoscopy in the PSS-H group. In the LPS-H group, there was one (3.3%) case of major bleeding( ≥ 500 mls). We recorded one vaginal cuff bleeding in PSS-H, whereas for LPS-H we reported 4 (13.3%) 30-days complications (p=0.651). No differences in visual analogue scale (VAS) score were recorded. A significant disparity was noted in cosmetic outcome at discharge (p=0.001), but not after 30 days.

CONCLUSION

We demonstrated for the first time, in a prospective comparison between PSS and LPS approaches, that PSS-H may represent a valid alternative to performing total hysterectomy in obese patients.

Robotic Single-Port Platform in General, Urologic, and Gynecologic Surgeries: A Systematic Review of the Literature and Meta-analysis

BACKGROUND

Robotic platforms have recently acquired progressive importance in different surgical fields, such as urology, gynecology, and general surgery. Through the years, new surgical robots have become available as single-port robotic platform. The study is aimed to value the single-port robotic platform characteristics in different surgical specialties.

METHODS

The terms "LESS" OR "single port" OR "single site" AND "robot" OR "robotic" were systematically used to search the PubMed and Scopus databases. A total of 57 studies were considered eligible for the present review. The articles included were divided according to the surgical field in which the study was conducted: General surgery (29 articles), Gynecology (18 articles), Urology (10 articles).

RESULTS

Most part of the articles showed the feasibility of robotic single-port surgical procedures and described advantages in terms of cosmetic, hospital stay, and in some series even cost reduction. A meta-analysis was conducted, showing a significant increment of complications using RSP if compared with SLPS and a trend (P = 0.008) when RSP was compared with LESS. The comparison of different techniques in terms of conversion to laparotomy did not show any significant difference.

CONCLUSION

Robotic single port potentially furnishes an important surgical and post-operatory improvement; however, some limits still prolong the surgical time and complication rate.

The Senhance™ surgical robotic system ("Senhance") for total hysterectomy in obese patients: a pilot study

This pilot study was aimed to value the feasibility and safety of Senhance Robotic Platform for hysterectomy in obese patients. Ten obese patients (30 < BMI < 40) underwent elective Senhance total extrafascial hysterectomy with bilateral salpingo-oophorectomy at the Division of Gynecologic Oncology of "Policlinico A. Gemelli" Foundation, Rome, Italy. Perioperative and postoperative outcomes data were recorded. The median age was 60 years (range 51-75) and the median BMI was 33.3 kg/m² (range 30.4-38.3). The median uterine weight was 112.5 g (range 77-225). Indication to total hysterectomy was early-stage (FIGO Stage IA) endometrial cancer in 100% of patients. The median operative time (OT) was 110 min (70-200). The median docking time was 10.5 min (5-25). The median estimated blood loss was 100 mL (50-200). No conversions to laparotomy were recorded. No intra- and 30-day postoperative complications were registered. The median ileus was 17 h (12-36) and the median time to discharge was 2 days (1-4). The median VAS scores registered at 2, 4, 12, and 24 h were, respectively, 2 (1-3), 2 (1-3), 4 (1-8), and 3 (1-5). Our study results suggest that Senhance platform could be safe for hysterectomy even in obese patients. More clinical data are needed to determine whether this approach would offer any additional benefits in a new middle line between standard laparoscopy and robotics.

Effects of nutraceuticals on quality of life and sexual function of perimenopausal women

PURPOSE

The aim of the study was to evaluate the effects of nutraceuticals containing Equol, Resveratrol, Quecitine and Passiflora (Zemiar^®, Avantgarde, Pomezia, Rome, Italy) on quality of life (QoL) and sexual function in perimenopausal women.

METHODS

Sixty perimenopausal women having vasomotor symptoms and being in the -1, +1a of the STRAW system (amenorrhea for longer than 60 days and FSH < 20 UI/L) were enrolled. The modified Kupperman Index (KI) was used to evaluate menopause symptoms. The Short Form-36 (SF-36), Female Sexual Function Index (FSFI) and the Female Sexual Distress Scale (FSDS) were used to assess QoL, sexual function and sexual distress, respectively. The study had two follow-ups at 3 and 6 months.

RESULTS

The women reported an improvement in the KI total score from the baseline (35 ± 4) to the 1st (21 ± 3, p < 0.05) and the 2nd (18 ± 2, p < 0.01) follow-ups. At the 1st follow-up, the women reported QoL improvements in some functions (p < 0.05); at the 2nd follow-up, they reported improvements in all categories (p < 0.001). At baseline, the total FSFI score was 23.1 ± 1.2 and the FSDS score was 18.1 ± 1.4, both indicating sexual dysfunction with sexual distress. FSFI and FSDS total scores did not change at the 1st follow-up (p = NS). On the contrary, at the 2nd follow-up, the FSFI score had risen to (27.6 ± 1.5) (p < 0.001) and the FSDS score had dropped to (11.3 ± 1.2) (p < 0.001).

CONCLUSIONS

Nutraceuticals can be effective in modulating the perimenopausal symptoms in women. The progressive reduction of the vasomotor symptoms reported by women over the nutraceutical usage could contribute to improve their QoL and sexual life.

Comparative, open-label prospective study on the quality of life and sexual function of women affected by endometriosis-associated pelvic pain on 2 mg dienogest/30 µg ethinyl estradiol continuous or 21/7 regimen oral contraceptive

PURPOSE

To evaluate the effects of a continuous regimen combined oral contraceptive (COC) containing 2 mg dienogest and 30 µg ethinyl estradiol (DNG/EE) compared to a 21/7 regimen on the quality of life (QoL) and sexual function in women affected by endometriosis-associated pelvic pain.

METHODS

Sixty-three women constituted the Study group treated with DNG/EE COC continuous regimen; 33 women were given DNG/EE COC in a 21/7 regimen. To define the endometriosis-associated pelvic pain, the Visual Analogic Scale was used. The Short Form-36, Female Sexual Function Index (FSFI) and the Female Sexual Distress Scale (FSDS) were used to assess QoL, sexual function and sexual distress, respectively. The study included two follow-ups.

RESULTS

At 3 and 6 months of treatment there was an improvement in pain of the Study group (p < 0.001). The Control group underwent pain improvement at the second follow-up (p < 0.05). At the first and the second follow-ups, the Study group reported QoL improvements in all categories (p < 0.001). The Control group reported QoL improvements in all categories at the second follow-up (p < 0.05). At the first and the second follow-ups of the Study group, the FSFI total score had risen (p < 0.001), and the FSDS score had dropped (p < 0.001). An improvement of the FSFI score and a reduction of the FSDS score of the Control group was observed at the second follow-up (p < 0.001), but not at the first follow-up (p = NS).

CONCLUSIONS

Women on DNG/EE COC continuous regimen reported a reduction of endometriosis-associated pelvic pain and there was an improvement of their sexual activity and their QoL that was better than the DNG/EE 21/7 conventional regimen.

Long-Term Survival for Platinum-Sensitive Recurrent Ovarian Cancer Patients Treated with Secondary Cytoreductive Surgery Plus Hyperthermic Intraperitoneal Chemotherapy (HIPEC)

BACKGROUND

To analyze the 5- and 7-year survival outcomes for women with platinum-sensitive recurrent epithelial ovarian cancer (REOC) who underwent secondary cytoreductive surgery (SCS) plus platinum-based hyperthermic intraperitoneal chemotherapy (HIPEC).

METHODS

From the electronic databases of the Department of Obstetrics and Gynecology at the Catholic University of the Sacred Heart of Rome and of the S. Orsola Hospital, University of Bologna, a consecutive series of REOC patients were selected using the following inclusion criteria: primary platinum-free interval (PFI-1) of 6 months or longer, completeness of secondary cytoreduction score (CC) of 1 or lower, minimum follow-up period of 48 months, Eastern Cooperative Group (ECOG) performance status at recurrence of 1 or less, and platinum-based HIPEC. Progression-free survival (PFS) and post-relapse survival (PRS) were calculated as the time between SCS + HIPEC and secondary recurrence or death, respectively.

RESULTS

The final study population included 70 women with platinum-sensitive REOC. The median follow-up time was 73 months (range 48-128 months), and the median PFI-1 was 19 months (range 6-100 months). At the time of recurrence, the median peritoneal cancer index was 7 (range 1-21), and a CC score of 0 was achieved for 62 patients (88.6 %). As the HIPEC drug, we used oxaliplatin in 17 cases (38.6 %) and cisplatin in 43 cases (61.4 %). No postoperative deaths were observed, and the complication rate for grades 3 and 4 disease was 8.6 %. The median PFS duration was 27 months (range 5-104 months), and the 5- and 7-year PRS rates were respectively 52.8 and 44.7 %, (median PRS 63 months).

CONCLUSIONS

The current study demonstrated favorable 5- and 7-year PRS rates for platinum-sensitive REOC patients undergoing SCS + HIPEC, which encourages the inclusion of patients in randomized clinical trials for definitive conclusions to be drawn.

Quality of life and sexual function of women affected by endometriosis-associated pelvic pain when treated with dienogest

PURPOSE

The aim of the study was to evaluate the effects of dienogest (DNG) on quality of life (QoL) and sexual function of women affected by endometriosis pain.

METHODS

Fifty-four women constituted the study group and were given 2 mg/daily DNG; 48 women were given non-steroidal anti-inflammatory drugs and constitut ed the control group. To define the endometriosis-associated pelvic pain, the Visual Analogic Scale (VAS) was used. The Short Form-36 (SF-36), the Female Sexual Function Index (FSFI) and the Female Sexual Distress Scale (FSDS) were used to assess the QoL, the sexual function and the sexual distress, respectively. The study included two follow-ups at 3 and 6 months.

RESULTS

Pain improvement was observed in the study group at 3 (p < 0.05) and 6 months (p < 0.001) of treatment. At the 1st follow-up, women reported QoL improvements in some functions (p < 0.05); at the 2nd follow-up, they reported improvement in all categories (p < 0.001). The FSFI score did not change at the 1st follow-up (p = NS). On the contrary, at the 2nd follow-up, it improved with respect to the baseline (p < 0.05). At the 2nd follow-up, the FSFI score had risen to 27.8 (p < 0.001) and the FSDS score had dropped to 11.3 (p < 0.001). No change was observed in the control group (p = NS).

CONCLUSIONS

The progressive reduction of the pain syndrome reported by women over the treatment period could contribute to improve the QoL and sexual life of women on DNG.

Beta-Thalassemia major and pregnancy

OBJECTIVE

It was studied the clinical management and the medical outcomes of 6 pregnancies in 5 women affected by Beta Thalassemia major, based on last guidelines and pharmacological treatments.

BACKGROUND

Paediatric Department and Department of Obstetrics and Gynaecology of the University of Catania.

METHODS

These patients were taken among a group of 116 women affected by beta-thalassemia major divided into three subgroups, according to the characteristics of their menstrual cycle: 1) women with primitive amenorrhoea, 2) women with secondary amenorrhoea and 3) women with normal menstruation. Only one woman, affected by primitive amenorrhoea, needed the induction of ovulation. An accurate and detailed pre-pregnancy assessment was effected before each conception. This was constituted by a series of essays, including checks for diabetes and hypothyroidism, for B and C hepatitis and for blood group antibodies. Moreover were evaluated: cardiac function, rubella immunity and transaminases. Other pregnancy monitoring, and cares during labour and delivery were effected according to usual obstetrics practice.

RESULTS

All the women were in labour when they were 38 week pregnant, and the outcome were six healthy babies born at term. There were no complications related to the pregnancy and to the immediate outcome after delivery.

CONCLUSIONS

The improvements of current treatments, especially in the management of iron deposits, the prolongation of survival rate, will result in a continuous increase of pregnancies in thalassemic women. Pregnancy is now a real possibility for women affected by such disease. Although numerous complications can occur, vigilant monitoring by both experienced obstetricians and hematologists can lead to successful pregnancy outcomes (Tab. 1, Fig. 1, Ref. 16).

Urethral sphincter innervation and clitoral blood flow after the transobturator (TOT) approach

INTRODUCTION AND HYPOTHESIS

The aim of the study was to exclude neurovascular damage due to prosthetic mini-invasive surgery using transobturator tape (TOT) by pre- and postoperative electromyography (EMG) of the striated urethral sphincter and a color Doppler ultrasonography evaluation of clitoral blood flow.

METHODS

A total of 25 women affected by clinical stress urinary incontinence (SUI) were enrolled. After undergoing urodynamic assessment, pelvic organ prolapse quantification, urine culture, Q-tip test, and stress test, each subject underwent color Doppler ultrasonography to record clitoral blood flow and EMG of the urethral sphincter with a needle electrode inserted through the mucosa into the muscle tissue before surgery. A single urogynecologist performed the TOT surgical technique for the treatment of all patients. Urogynecologic examination, EMG, and color Doppler ultrasound follow-up were performed at 1 and 6 months after surgery.

RESULTS

At the urogynecologic examination performed 1 and 6 months after the TOT approach the stress test was negative, urethral hypermobility was reduced, and sling exposure was not observed for each patient. There was no statistically significant difference in electromyographic values (p > 0.05) in both the follow-ups with regard to baseline values. Pulsatility index (PI), resistance index (RI), and peak systolic velocity (PSV) values increased during the first follow-up (p < 0.01); PI and RI values increased during the second follow-up with respect to baseline values (p < 0.01)

CONCLUSIONS

TOT prosthesis surgery, avoiding denervation and devascularization of pelvic structures, does not damage the urethral sphincter.

Female genital tissue concentrations of roxithromycin

A new macrolide, roxithromycin, appears to have some interesting pharmacokinetic characteristics dissimilar to those of erythromycin, e.g. it has the unusual property of a long serum half-life and the possibility of once daily dosing. Moreover tissue levels are higher than those obtained with other macrolides, and the drug is still present in the tissues up to 24 h. after dosing. The pharmacokinetics of roxithromycin were studied in 36 women undergoing gynecological surgery, and divided by means of the time of sampling into six different groups. Each group received an initial 300 mg dose followed by 8 successive doses of 150 mg at 12 h intervals. Blood and tissues samples were taken during surgery at 2, 6, 9, 12, 18 and 24 h after the last dose of roxithromycin and the patients were then allocated to one of the six groups by means of the sampling time. Tissue fragments were obtained from ovary, fallopian tubes, endometrium, myometrium, cervix and vagina immediately after the surgical resection of the organs. Tissue and serum concentrations were determined by the microbiological method using Sarcina lutea ATCC 9341; the lowest limit of detection was 0.01 microg/ml or 0.01 microg/g. Roxithromycin reached the highest concentration at the 9th hour after last administration and its tissue levels would encourage a wide use of this drug as a satisfactory alternative to tetracyclines for the therapy of some gynecological infections.

Serum IgA antibodies in HSV asymptomatic genital infections

Cervico-vaginal swabs and serum samples from 81 women without herpes-associated clinical symptoms were examined for virus isolation and for the presence of IgA antibodies to herpes simplex virus (HSV) using the indirect fluorescent antibody technique. Nineteen of the 81 women were followed up for 2 years. Blood samples and swabs from cutaneous lesions were obtained from another group of 20 women (medical staff) with herpes labialis. By analysing the specific anti-HSV IgA antibodies, a higher geometric mean titre (GMT) was found in women with positive HSV-2 isolation (GMT = 380.03), as opposed to the GMT observed in women with negative HSV-2 (GMT = 63.43) or positive HSV-1 isolation (GMT = 55.15). Results from the longitudinal study also demonstrated that positive virus isolation always correlated with a marked rise in serum IgA antibody to HSV.
