IFTT in children and adolescents-single-center experience and systematic review of literature.

PURPOSE: Isolated fallopian tube torsion (IFTT) is defined by rotation of the fallopian tube around itself without involving the ipsilateral ovary. It is a rare cause of acute lower abdominal pain in (adolescent) girls, but is commonly overlooked. Due to its rarity, literature is still scarce. Currently there is no generally accepted management and treatment. METHODS: A retrospective analysis of all IFTT cases treated in our institution was performed. In addition, a systematic literature research on pediatric IFTT was carried out on Medline/ PubMed database according to PRISMA principles using predefined search terms and inclusion criteria. Patient characteristics regarding age, clinical symptoms, diagnostic methods, treatment, and follow-up were analyzed. RESULTS: Three of our patients and fifty-nine reports totaling one hundred seventy girls were included in the analysis. Mean age was 13.0 years. Left tube was slightly more often affected (52.9%). Abdominal pain was present in 99.4% of cases accompanied with nausea in 57.1%. In only 16.4%, correct preoperative diagnosis was made. Salpingectomy was the most common treatment in 111 (66.9%) cases, 55 (33.1%) patients were treated with detorsion of the tube (organ-sparing management). Girls with symptoms longer than 1 day had a significant higher rate of salpingectomy (95% CI, P = 0.0323). CONCLUSION: When IFTT is suspected, emergency laparoscopy should be performed to possibly preserve future reproductive potential. In case of detorsion and reinstated blood supply, organ-preserving management should be performed with simultaneous addressment of concomitant pathology if possible. Sufficient long-term follow-up must be assured to get significant results to introduce guidelines for children and adolescents.

Salpingectomy for ectopic pregnancy reduces ovarian cancer risk-a nationwide study.

Recent studies propose fallopian tubes as the tissue origin for many ovarian epithelial cancers. To further support this paradigm, we assessed whether salpingectomy for treating ectopic pregnancy had a protective effect using the Taiwan Longitudinal National Health Research Database. We identified 316 882 women with surgical treatment for ectopic pregnancy and 3 168 820 age- and index-date-matched controls from 2000 to 2016. In a nested cohort, 91.5% of cases underwent unilateral salpingectomy, suggesting that most surgically managed patients have salpingectomy. Over a follow-up period of 17 years, the ovarian carcinoma incidence was 0.0069 (95% confidence interval [CI] = 0.0060 to 0.0079) and 0.0089 (95% CI = 0.0086 to 0.0092) in the ectopic pregnancy and the control groups, respectively (P < .001). After adjusting the events to per 100 person-years, the hazard ratio (HR) in the ectopic pregnancy group was 0.70 (95% CI = 0.61 to 0.80). The risk reduction occurred only in epithelial ovarian cancer (HR = 0.73, 95% CI = 0.63 to 0.86) and not in non-epithelial subtypes. These findings show a decrease in ovarian carcinoma incidence after salpingectomy for treating ectopic pregnancy.

Comparison of salpingectomy and tubal detorsion procedures after experimental ischemia-reperfusion injury in a rat fallopian tube model: biochemical and histopathological evaluation.

OBJECTIVE: To compare salpingectomy and detorsion procedures and investigate the biochemical and histopathological changes in the fallopian tubes in the experimentally isolated fallopian tube torsion model in rats. DESIGN: Experimental study. SETTING: Experimental surgery laboratory in a training and research hospital. ANIMAL(S): Twenty-seven Sprague-Dawley rats in the reproductive period. INTERVENTION(S): Group 1, control group (n = 6); group 2, bilateral total salpingectomy group after 4 hours of tubal ischemia (n = 7); group 3: 4 hours of bilateral tubal ischemia plus 1 week of reperfusion (n = 7); and group 4, 4-hour period of bilateral tubal ischemia plus 30 days of reperfusion (n = 7). A 22-gauge catheter was administered before and after surgery using methylene blue through the uterine horn of the rat to evaluate tubal patency. MAIN OUTCOME MEASURE(S): Preoperative and postoperative serum antimüllerian hormone (AMH) levels, histopathological examination of the rat tuba uterine and histopathological damage scores, antioxidant compounds (superoxide dismutase [SOD], catalase, and glutathione peroxidase [GSH-Px]), and oxidative stress end product levels (malondialdehyde [MDA] and 8-hydroxy-2'-deoxyguanosine [8-OHdG]). RESULT(S): Although a significant difference was observed in the tissue SOD, GSH-Px, MDA, and 8-OHdG values, no significant difference was observed between the groups in serum samples. The tissue SOD and tissue GSH-Px levels in group 2 significantly decreased, and a significant increase was observed in the tissue MDA and 8-OHdG values in group 2. Among the histopathological parameters, epithelial changes, vascular congestion, and the total fallopian tube mean damage score of 4 showed a significant decrease in group 4. When the methylene blue transitions before and after ischemia-reperfusion injury were compared, the values of the methylene blue transition after ischemia-reperfusion injury in groups 2-4 significantly decreased. When the serum AMH levels were analyzed, the postoperative AMH value in group 2 significantly increased. CONCLUSION(S): This study reveals that biochemical and histopathological improvement is observed in the fallopian tube tissues gradually when the detorsion procedure is performed for the necrotized tubal tissue instead of salpingectomy. Although there is restoration of epithelial integrity after reperfusion, tubal passage remains absent. CLINICAL TRIAL REGISTRATION NUMBER: This study was approved by the Local Ethics Committee for Animal Experiments of the Health Sciences University, Istanbul Hamidiye Medicine Faculty (approval number 27.05.2022-9269). The study followed the ethics standards recommended by the Declaration of Helsinki.

Isolated fallopian tube torsion: A systematic review of case reports.

OBJECTIVE: To combine all literature describing cases of isolated fallopian tube torsion in adult non pregnant patients in a systematic manner, to optimize knowledge and practice both for diagnosis and management. STUDY DESIGN: EMBASE and PubMed databases were searched for the terms 'tubal' OR 'fallopian tube' AND 'isolated' AND 'torsion' from the inception of these databases to July 5, 2023. All case reports or case series of adult patients (18 years or older) with isolated fallopian tube torsion were included. Exclusion criteria included: all other study types; cases involving children and adolescents (less than 18 years old); pregnant patients of all trimesters; tubo-ovarian torsion; studies not published in English; duplicates and those not available in text. Following the database search, two authors independently screened the studies and search results were subsequently reported in accordance with PRISMA guidelines. Data was extracted independently by two authors and analysed using Excel. All cases were assessed for bias using a modified version of the tool proposed by Murad et al. RESULTS: 92 unique articles enrolling 131 individual cases were included in this systematic review. Isolated fallopian tube torsion most commonly occurs during reproductive ages between 18 and 45 years. It is uncommon in postmenopausal women. The most common presenting symptoms include unilateral lower abdominal or pelvic pain along the affected side with nausea and vomiting. Risk factors can be intrinsic or extrinsic and can include conditions such as hydrosalpinx, sterilization, pelvic inflammatory disease or cysts. Ultrasound is the optimal imaging modality however Computed Tomography and Magnetic Resonance Imaging can also be used. Imaging in general has low sensitivity, however isolated fallopian tube torsion can be identified with appropriate expertise. The gold standard for isolated fallopian tube torsion management is laparoscopy and detorsion however currently, the most common intervention performed is salpingectomy. CONCLUSIONS: Isolated fallopian tube torsion is a rare but important gynaecological emergency with significant fertility implications. This study summarizes the most common presentations, investigation findings and surgical interventions in patients with isolated fallopian tube torsion. This study also emphasizes the importance of clinicians maintaining a high degree of suspicion and low threshold for early laparoscopic intervention to retain fertility.

Laparoscopic resection of a salpingectomy stump remnant during early pregnancy: the diagnostic challenge posed in diagnosing a heterotopic stump pregnancy.

In this report, we present a case of a woman admitted in her first trimester of pregnancy with significant intraperitoneal haemorrhage from a left tubal stump remnant occurring concurrent to a viable intrauterine pregnancy. The patient was resuscitated and treated successfully with laparoscopic removal of her stump remnant to achieve haemostasis. However, despite extensive investigation, the pathology of her haemorrhagic stump remained inconclusive. Stump ectopic pregnancy is an established phenomenon, although it presents a diagnostic challenge when occurring as a heterotopic pregnancy. Further, persisting trophoblastic tissue is a rare but established feature of incomplete removal of ectopic pregnancy post salpingectomy. Here, we discuss challenges of diagnosis in such cases and present a case report of a presumed stump remnant heterotopic pregnancy from spontaneous conception.

Gasless transvaginal natural orifice transluminal endoscopic surgery for hysterectomy and salpingectomy on a robot platform with flexible devices in a porcine model.

In this report, we described a new technique of gasless V-NOTES for hysterectomy and salpingectomy on a robotic platform with flexible devices in a porcine model. As a result, the gynecological procedures were successfully completed. The total operative time was 110 min, while the docking time was 10 min. The estimated blood loss was estimated to be 10 mL with no intraoperative complications. It revealed that gasless V-NOTES for hysterectomy and salpingectomy on a robotic platform with flexible devices appeared to be feasible and safe in the porcine model and has the potential for clinical use in human beings.

Giving birth after fertility-sparing treatment for primary leiomyosarcoma of the fallopian tube.

Primary leiomyosarcoma of the fallopian tube (PLFT) is an extremely rare gynecological malignancy that has only been described in case reports. Fertility-sparing treatment for PLFT has not been reported previously. A 24-year-old nulligravida woman was diagnosed with stage IC1 PLFT in the right fallopian tube after experiencing right lower quadrant pain for 2 weeks. She underwent laparoscopic right salpingectomy to preserve fertility followed by adjuvant chemotherapy with gemcitabine/docetaxel. She subsequently became pregnant spontaneously, delivering a term baby 27 months after treatment. This appears to be the only report of the use of fertility-preserving treatment for PLFT. The success of the treatment provides valuable information on the preservation of fertility in young women with PLFT.

Hysteroscopic Transillumination as a Guide for Laparoscopic Excision of Rudimentary Uterine Horn: A Winning Duo.

STUDY OBJECTIVE: Anatomic anomalies of the female reproductive genital tract affect approximately 5.5% of women [1]. The hemiuterus or class U4 by the European Society of Human Reproduction and Embryology / European Society for Gynaecological Endoscopy 2013 classification is a rare congenital malformation defined as a unilateral uterine development, with a contralateral part that could be either incompletely formed or absent. This class is divided into 2 subclasses depending on the presence or not of a functional rudimentary cavity (U4a/U4b) [2]. This work aimed to share our experience performing an hysteroscopic and laparoscopic combined technique to surgically manage this uterine malformation exploiting the hysteroscopic transillumination. DESIGN: A step-by-step explanation of surgical technique with narrated video footage. SETTING: Tertiary Level Academic Hospital "IRCCS Azienda Ospedaliero - Universitaria di Bologna" Bologna, Italy. INTERVENTIONS: A 32-year-old woman with a symptomatic (severe dysmenorrhea and chronic pelvic pain) suspected U4a uterine malformation diagnosed at our center was scheduled for laparoscopic removal of the right uterine horn and ipsilateral salpingectomy exploiting the contemporary hysteroscopic transillumination guidance. We selected this approach to avoid possible complications owing to the anatomic anomalies that are very common in these cases [3,4]. After coagulation and section of the right round ligament at the uterine angle and opening of the right broad ligament, access to the retroperitoneum was obtained to directly visualize the entire course of ureter and the uterine artery. The right uterine artery was coagulated and sectioned at the uterus. Then, the hysteroscope was introduced to the uterine fundus and the light source brightness was increased up to 100% to allow an adequate transmural visualization of the uterine defect from the laparoscope. Once the defect edge was well highlighted, the right uterine horn was isolated and removed using a monopolar hook, taking care to preserve an adequate amount of myometrium. A double layer running suture with barbed absorbable thread (V-Loc) for reconstructive purposes was performed. The specimen was retrieved inside an endobag to allow a safe extraction. Right salpingectomy was then performed. CONCLUSION: Considering the great anatomic variability of this condition, this type of surgery is not always simple. Indeed, the borders between the uterus and the rudimentary uterine horn are often not perfectly recognizable; this can lead to accidental removal of healthy myometrium and increase the risk of perioperative bleeding [5]. In our experience, the combined hysteroscopic and laparoscopic combined technique allows the surgeon to better delimit the borders of the hemiuterus, providing a more conservative and safer surgery. Hysteroscopic transillumination offers the possibility to modulate the radicality in the resection of the rudimentary horn and in the final treatment of dysmorphism.

Screening and prevention of ovarian cancer.

Ovarian cancer remains the most lethal gynaecological malignancy with 314 000 cases and 207 000 deaths annually worldwide. Ovarian cancer cases and deaths are predicted to increase in Australia by 42% and 55% respectively by 2040. Earlier detection and significant downstaging of ovarian cancer have been demonstrated with multimodal screening in the largest randomised controlled trial of ovarian cancer screening in women at average population risk. However, none of the randomised trials have demonstrated a mortality benefit. Therefore, ovarian cancer screening is not currently recommended in women at average population risk. More frequent surveillance for ovarian cancer every three to four months in women at high risk has shown good performance characteristics and significant downstaging, but there is no available information on a survival benefit. Population testing offers an emerging novel strategy to identify women at high risk who can benefit from ovarian cancer prevention. Novel multicancer early detection biomarker, longitudinal multiple marker strategies, and new biomarkers are being investigated and evaluated for ovarian cancer screening. Risk-reducing salpingo-oophorectomy (RRSO) decreases ovarian cancer incidence and mortality and is recommended for women at over a 4-5% lifetime risk of ovarian cancer. Pre-menopausal women without contraindications to hormone replacement therapy (HRT) undergoing RRSO should be offered HRT until 51 years of age to minimise the detrimental consequences of premature menopause. Currently risk-reducing early salpingectomy and delayed oophorectomy (RRESDO) should only be offered to women at increased risk of ovarian cancer within the context of a research trial. Pre-menopausal early salpingectomy is associated with fewer menopausal symptoms and better sexual function than bilateral salpingo-oophorectomy. A Sectioning and Extensively Examining the Fimbria (SEE-FIM) protocol should be used for histopathological assessment in women at high risk of ovarian cancer who are undergoing surgical prevention. Opportunistic salpingectomy may be offered at routine gynaecological surgery to all women who have completed their family. Long term prospective opportunistic salpingectomy studies are needed to determine the effect size of ovarian cancer risk reduction and the impact on menopause.

Methotrexate treatment for peritoneal trophoblastic implants after laparoscopic salpingectomy and secondary laparoscopic excision of ectopic pregnancy.

Ectopic pregnancy is a one of the primary causes of maternal mortality in first trimester. The most common site of ectopic pregnancy is the fallopian tube. Surgical management of tubal ectopic pregnancy includes salpingotomy or salpingectomy. Persistent ectopic pregnancy can happen after salpingotomy due to incomplete removal of ectopic tissue. However, it is very rare after salpingectomy. In our case, the patient had right-sided salpingectomy and histology confirmed right-sided tubal ectopic pregnancy. She presented 19 days' later with abdominal pain, haemoperitoneum and persistent high beta-HCG (B-HCG). A second laparoscopy was done and tissue implants were removed from the surface of the right ovary and the omentum, which were confirmed to be products of conception on histology. The pain settled postoperative. However, B-HCG remained high postoperative. Subsequently, methotrexate treatment was given leading to full resolution of the pregnancy with one dose.

Regret in the Modern Contraceptive Landscape: Evaluating Regret in Patients Undergoing Tubal Ligation or Bilateral Salpingectomy for Contraception.

OBJECTIVE: To estimate the prevalence of regret among Canadians undergoing tubal ligation or bilateral salpingectomy for contraception in the context of widely available, highly effective, and tolerable reversible contraceptive methods including long-acting reversible contraceptives. METHODS: We performed an online cross-sectional survey of regret following tubal sterilization using Qualtrics software. A convenience sample was used to recruit Canadian residents between the ages of 18 and 60 years who had undergone tubal ligation or salpingectomy for contraception. The online survey was advertised on 3 social media platforms: Facebook, Twitter, and Instagram. RESULTS: We obtained survey results for 844 Canadian residents. Regret was reported by 15.9% of respondents. Consistent with existing literature, factors associated with regret included younger age at the time of the procedure, a change in relationship status, and having the procedure performed at the time of a pregnancy. Surprisingly, 9.5% of respondents reported an element of coercion, 4.5% were unaware the procedure was considered permanent contraception, and 33.3% did not recall their provider discussing alternative forms of contraception with them prior to surgery. CONCLUSION: We found that the prevalence of regret following tubal sterilization has not changed with the widespread availability of highly effective reversible contraceptive methods. However, most patients choosing permanent contraception will be satisfied with their decision. Shared decision-making should respect the autonomy of each patient to make their own decisions regarding the most acceptable family planning method for their circumstances.

Contraception and sterilization selection at delivery among pregnant patients with malignancy.

INTRODUCTION: Since malignancy during pregnancy is uncommon, information regarding contraception selection or sterilization at delivery is limited. The objective of this study was to examine the type of long-acting reversible contraception or surgical sterilization procedure chosen by pregnant patients with malignancy at delivery. MATERIAL AND METHODS: This cross-sectional study queried the Healthcare Cost and Utilization Project's National Inpatient Sample in the USA. The study population was vaginal and cesarean deliveries in a hospital setting from January 2017 to December 2020. Pregnant patients with breast cancer (n = 1605), leukemia (n = 1190), lymphoma (n = 1120), thyroid cancer (n = 715), cervical cancer (n = 425) and melanoma (n = 400) were compared with 14 265 319 pregnant patients without malignancy. The main outcome measures were utilization of long-acting reversible contraception (subdermal implant or intrauterine device) and performance of permanent surgical sterilization (bilateral tubal ligation or bilateral salpingectomy) during the index hospital admission for delivery, assessed with a multinomial regression model controlling for clinical, pregnancy and delivery characteristics. RESULTS: When compared with pregnant patients without malignancy, pregnant patients with breast cancer were more likely to proceed with bilateral salpingectomy (adjusted odds ratio [aOR] 2.30) or intrauterine device (aOR 1.91); none received the subdermal implant. Pregnant patients with leukemia were more likely to choose a subdermal implant (aOR 2.22), whereas those with lymphoma were more likely to proceed with bilateral salpingectomy (aOR 1.93) and bilateral tubal ligation (aOR 1.76). Pregnant patients with thyroid cancer were more likely to proceed with bilateral tubal ligation (aOR 2.21) and none received the subdermal implant. No patients in the cervical cancer group selected long-acting reversible contraception, and they were more likely to proceed with bilateral salpingectomy (aOR 2.08). None in the melanoma group chose long-acting reversible contraception. Among pregnant patients aged <30, the odds of proceeding with bilateral salpingectomy were increased in patients with breast cancer (aOR 3.01), cervical cancer (aOR 2.26) or lymphoma (aOR 2.08). The odds of proceeding with bilateral tubal ligation in pregnant patients aged <30 with melanoma (aOR 5.36) was also increased. CONCLUSIONS: The results of this nationwide assessment in the United States suggest that among pregnant patients with malignancy, the preferred contraceptive option or method of sterilization at time of hospital delivery differs by malignancy type.

Bilateral salpingectomy as an option of permanent contraception at time of caesarean section: A survey of practice.

BACKGROUND: Opportunistic bilateral salpingectomy during benign gynaecologic surgery is advocated as a risk-reducing strategy due to the inverse association of epithelial ovarian cancers observed in epidemiological studies in a low-risk setting. Currently, no formal guidance exists for permanent surgical contraception at time of caesarean section in Australia. AIMS: Our aim was to survey Fellows of the Royal Australian and New Zealand College of Obstetricians and Gynaecologists (RANZCOG) regarding bilateral salpingectomy compared to other procedures offered for permanent contraception at the time of caesarean section. MATERIALS AND METHODS: An online survey was utilised to collect clinician demographics, opinions, barriers, and justifications in regard to options of permanent surgical contraception at time of caesarean section. RESULTS: Bilateral salpingectomy was identified as the most effective method of permanent contraception at time of caesarean section. However, only 62% of respondents offer the procedure as a method of permanent contraception. The two most common reasons for clinicians to offer bilateral salpingectomy at time of caesarean section were evidence suggesting a link between the fallopian tube and gynaecological cancer (80%) and efficacy as a permanent form of contraception (16%). The primary barrier identified by 51% of respondents was perceived increased risk of surgical complications, followed by reasoning that it would not allow the possibility of future tubal reversal. CONCLUSION: This study identifies diverse opinions on surgical approach to permanent contraception at time of caesarean section and offered by clinicians of RANZCOG. Further research is required to establish safety profiles and short- and long-term risks of bilateral salpingectomy.

Complications after opportunistic salpingectomy compared with tubal ligation at cesarean section: a retrospective cohort study.

OBJECTIVE: To compare perioperative and postoperative complications in patients who underwent opportunistic salpingectomy (OS) (removal of the fallopian tubes for ovarian cancer risk reduction during another surgery) at the time of cesarean section (C-section) with those in patients who underwent tubal ligation. DESIGN: A population-based, retrospective cohort study. SETTING: British Columbia, Canada. PATIENT(S): A total of 18,184 patients were included in this study, of whom 8,440 and 9,744 underwent OS and tubal ligation, respectively. INTERVENTION(S): Patients who underwent OS during a C-section were compared with those who underwent tubal ligation during a C-section. MAIN OUTCOME MEASURE(S): We examined the perioperative outcomes, including operating room time, length of hospital stay, surgical complications such as infections, anemia, incision complications, injury to a pelvic organ, or operating room return; postoperative complications, including physician visits for a postoperative infection or visits that resulted in ultrasound or laboratory examinations and hospital readmissions in the 6 weeks after discharge; and likelihood to fill a prescription for antibiotics or analgesics. RESULT(S): The OS group had decreased odds of perioperative complications compared with the tubal ligation group (adjusted odds ratio [aOR], 0.77; 95% confidence interval [CI], 0.61-0.99). Patients who underwent OS did not have increased risks of physician visits for surgical complications, such as infection, or hospital readmissions in the 6 weeks after hospital discharge. In addition, these patients had 18% and 23% increased odds of filling prescriptions for nonsteroidal anti-inflammatory drugs (aOR, 1.18; 95% CI, 1.07-1.28) and opioids (aOR, 1.23%; 95% CI, 1.12-1.35), respectively. CONCLUSION(S): In this population-based, real-world study of OS at C-section, we report decreased perioperative complications and no difference in postoperative complications between patients who underwent OS and those who underwent tubal ligation. Patients who underwent OS had an increased likelihood of filling a prescription for nonsteroidal anti-inflammatory drugs and opioids in the 6 weeks after hospital discharge. This result should be interpreted with caution because we did not have data on over-the-counter medication use and, thus, not all prescription analgesics were captured in our data. Our data suggest that OS after C-section is a safe way to provide effective contraception and ovarian cancer risk reduction.

Beyond Sterilization: A Comprehensive Review on the Safety and Efficacy of Opportunistic Salpingectomy as a Preventative Strategy for Ovarian Cancer.

Ovarian cancer (OC) is Canada's third most common gynecological cancer, with an estimated 3000 new cases and 1950 deaths projected in 2022. No effective screening has been found to identify OC, especially the most common subtype, high-grade serous carcinoma (HGSC), at an earlier, curable stage. In patients with hereditary predispositions such as BRCA mutations, the rates of HGSC are significantly elevated, leading to the use of risk-reducing salpingo-oophorectomy as the key preventative intervention. Although surgery has been shown to prevent HGSC in high-risk women, the associated premature menopause has adverse long-term sequelae and mortality due to non-cancer causes. The fact that 75% of HGSCs are sporadic means that most women diagnosed with HGSC will not have had the option to avail of either screening or prevention. Recent research suggests that the fimbrial distal fallopian tube is the most likely origin of HGSC. This has led to the development of a prevention plan for the general population: opportunistic salpingectomy, the removal of both fallopian tubes. This article aims to compile and review the studies evaluating the effect of opportunistic salpingectomy on surgical-related complications, ovarian reserve, cost, and OC incidence when performed along with hysterectomy or instead of tubal ligation in the general population.
