Contemporary Trends in Laparoscopy and Ovarian Sparing Surgery for Ovarian Torsion in the Pediatric Population.

PURPOSE: Although total oophorectomy (TO) was historically performed in cases of nonviable-appearing ovaries, considerable evidence has demonstrated equivalent outcomes after ovarian sparing surgery (OSS) as well as long-term fertility preservation benefits. This study sought to compare outcomes of OSS and TO for patients with ovarian torsion. METHODS: Females <21 years old admitted for ovarian torsion were identified from the Nationwide Readmissions Database (2016-2018) and stratified by OSS or TO. Propensity score-matched analysis (PSMA) utilizing >50 covariates (demographics, medical comorbidities, ovarian diagnoses, etc.) was constructed between those receiving TO and OSS. RESULTS: There were 3,161 females (median 15 [12-18] years) with ovarian torsion, and concomitant pathologies included cysts (42%), benign masses (25%), and malignant masses (<1%). Open approaches were more common (52% vs. 48% laparoscopic), and ovarian resection (OSS or TO) was performed in 87% (39% OSS and 48% TO). OSS was more commonly performed with laparoscopic detorsions (60% vs. 40% TO), while TO was more frequent in open operations (59% vs. 41% TO; both p < 0.001). No differences in overall readmissions (7% OSS vs. 8% TO) or readmissions for recurrent torsion (<1% overall) and ovarian masses (<1%) were observed (both groups <1%; p = 0.612). After PSMA, laparoscopy was still utilized less frequently with TO (39% vs. 53%; p < 0.001) despite similar rates of malignant masses. CONCLUSIONS: Overall, these data offer additional support for the current practice guidelines that give preference to OSS as the primary method of treatment for pediatric ovarian torsion in the majority of cases. LEVEL OF EVIDENCE: III. TYPE OF STUDY: Retrospective Comparative Study.

Clinical characteristics of adnexal torsion and role of ovarian sparing surgery: a clinical retrospective analysis.

OBJECTIVES: To analyze the clinical characteristics and risk factors related to necrosis of adnexal torsion (AT) and improve the application of ovarian-sparing surgery (OSS). MATERIAL AND METHODS: Data of 142 patients with 144 surgically confirmed AT lesions between October 2011 and December 2021 were retrospectively analyzed. RESULTS: The risk of torsion caused by tumors was higher than that caused by tumor-like lesions (p = 0.003). The incidence of right adnexal necrosis was higher than that of left adnexal necrosis (p = 0.03). There were no significant differences in adnexal necrosis or onset time (p = 0.29) between groups. The main risk factor for adnexal necrosis was the degree of torsion with a threshold of 510°. The size of adnexal mass and the degree of torsion increased linearly with age. The OSS rate was 59.7% for all patients, and 71.6% in the premenopausal women. No serious complications occurred in any of the patients. CONCLUSIONS: Age, histopathological type, adnexal size, degree of torsion, and pelvic anatomical structure are risk factors for AT and adnexal necrosis. There is no infinite correlation between adnexal necrosis and onset time. Adnexal size is the main risk factor for AT, and along with the risk of adnexal necrosis, increases with age. The degree of torsion is the main risk factor for adnexal necrosis, and torsional severity increases with age. OSS is safe and does not increase the incidence of postoperative complications.

Subtrochanteric osteotomy in the management of femoral maltorsion results in anteroposterior malcorrection of the greater trochanter: computed simulations of 3D surface models of 100 cadavers.

AIM: The purpose of this study was to investigate the greater trochanter's (GT) behaviour in simulated subtrochanteric osteotomy. MATERIALS AND METHODS: Measurement of functional and anatomical femoral torsion, and position of the GT and lesser trochanter was performed using 3-dimensional (3D) surface models of 100 cadaveric femora. Femoral torsion between 2° and 22° was defined as normal, femora with <2° and >22° of femoral torsion were assigned to the low- and high-torsion group. Subtrochanteric osteotomy was simulated to normalise torsional deformities to 12°. RESULTS: With subtrochanteric osteotomy, functional torsion was simultaneously corrected while adjusting anatomical torsion (R2 = 0.866, p < 0.001). Compared to the normal-torsion group, an anteroposterior (AP) overcorrection of ±0.5 centimetres (range 0.02-1.1 cm) of the GT resulted in the high- and low-torsion group, respectively (p < 0.001): Mean AP GT distance to a standardised coronal plane was 2.1 ± 0.3 cm (range 12-30 cm) in the normal-torsion group compared to 1.61 ± 0.1 cm (range 1.4-1.71 cm) and 2.6 ± 0.6 cm (range 1.8-3.6 cm) for the corrected high and low-torsion groups, respectively. The extent of the GT shift in AP direction correlated strongly with the extent to which anatomical femoral torsion was corrected (R2 = 0.946; p < 0.001). CONCLUSIONS: Subtrochanteric osteotomy for femoral maltorsion reliably adjusts anatomical and functional torsion, but also results in a ±1 cm AP shift of the GT per 10° of torsional correction. However, this effect of the procedure is most likely not clinically relevant in relation to hip abductor performance.

The protective effect of erythropoietin on ischemia- reperfusion injury caused by ovarian torsion-detorsion in the experimental rat model.

Ovarian torsion is one of the most dangerous gynecological emergencies requiring surgery. A total of 50%-90% ovarian torsion cases are caused by physiological cysts, endometriosis, and other benign or malignant ovarian neoplasms. The aim of the study was to investigate the effects of erythropoietin (EPO) treatment on ischemia/reperfusion (IR) injury caused by ovarian torsion/detorsion (T/D) injury. Thirty female Wistar albino rats were divided into five groups as follows: Group I: Control; Group II: Torsion (T); Group III: Torsion/Detorsion(T/D); Group IV: Torsion/Detorsion (T/D) + EPO; Group V: EPO. Sections of the ovaries were evaluated for histopathological changes with hematoxylin and eosin stain, a immunohistochemical assay for caspase 3 expression, and the TUNEL assay for apoptosis. Ovarian sections from torsion/detorsion and torsion groups showed more hemorrhage, vascular congestion, edema, degenerative granulosa, and stromal cells. Fewer histopathological changes were found in EPO and T/D + EPO groups. Caspase 3 and TUNEL positive cells were significantly increased in the torsion/detorsion group as compared with the other groups (p < 0.05). Treatment with erythropoietin decreased the number of caspase 3 and TUNEL positive cells. The results of the study showed that erythropoietin administration is effective for recovery from degenerative changes in the ovary induced by the torsion-detorsion injury.

Characteristics of ovarian necrosis in the neonatal ovarian tumor: a single-center retrospective study and review of literature.

To analyze the characteristics of ovarian necrosis in the neonatal ovarian tumor, and review treatments for ovarian torsion in neonates. Neonates with ovarian tumors undergoing surgery in Fujian Maternal and Child Health Hospital (Fujian Children's Hospital) from February 2016 to August 2021 were analyzed retrospectively. Patients were divided into the ovarian necrosis group and control group (without necrosis). Demographic characteristics, prenatal and postnatal examination, operation, and pathological findings were compared and the relevant factors of ovarian necrosis were discussed. 26 neonates were included, 12 in necrosis group and 14 in control group. The maximum diameter of the tumor in necrosis group was smaller than that in control group (P < 0.01). The preoperative CRP in necrosis group was significantly higher than that in control group (P < 0.05). There were no significant differences between two groups in the timeliness of surgery, pathological types, and length of postoperative hospital stay. About 26% of neonatal ovarian torsion could be rescued. Neonatal ovarian necrosis is characterized by a smaller tumor size and a higher preoperative CRP level. Timely surgery after birth might not change the ovarian outcome, but ovarian detorsion could be attempted in neonates to save residual ovarian function.

Rethinking ovary preservation by adnexal torsion reversal in adolescents: a case of delayed diagnosis.

BACKGROUND: This article discusses the management of an adolescent woman with a delayed diagnosis of adnexal torsion (AT) whose ovaries were successfully preserved. CASE PRESENTATION: The patient was a 14-year-old female teen admitted with the chief complaint of lower abdominal pain for 3 days and worsening pain for 2 days. Magnetic resonance imaging suggested a high possibility of torsion in the anterosuperior uterine mass and was accompanied by severe ovarian edema, bleeding, and enlargement. Intraoperatively, the left fallopian tube was characterized by thickening and torsion and appeared blackish purple. The left fallopian tube paraovarian cyst was about 20 cm in size, and the left adnexa was twisted 1080° along the left infundibulopelvic ligament (suspensory ligament of the left ovary). The left ovary appeared blackish purple, with an enlarged diameter of about 10 cm. At the request and with the informed consent of the patient's parents, we preserved the left ovary and removed the left fallopian tube. The results of the endocrine, ultrasound, and tumor marker tests were normal 1 month after surgery. Follicles and blood flow signals seen in ultrasound examinations indirectly proved the successful preservation of the left ovary in the follow-up. CONCLUSIONS: Our attempt to preserve the ovaries in an adolescent with a delayed diagnosis of AT was successful.

Omental torsion at the time of COVID-19 in Northern Italy: a case report of conservative management with a review of the pertinent literature.

BACKGROUND AND AIM: In middle-aged men, omental torsion (OT) can be a cause of acute abdomen.The right side of the omentum is longer, heavier and more mobile than the left one and, as a consequence, it can twist more easily on its vascular axis. Consequently, OT localization in the lower right quadrant is more frequent, and therefore it can mimic acute appendicitis clinical onset.In most cases, OT is defined as "primary" in the absence of any other underlying pathologies, or,  rarely, "secondary", when caused by other intra-abdominal diseases such as inguinal hernia, tumors, cysts or post-surgical scarring. To date, clinical diagnosis of OT still remains a challenging one in a preoperative setting and most cases are diagnosed intraoperatively. If diagnosis is correctly achieved preoperatively by adequate imaging examinations, most patients presenting with OT do not undergo surgery anymore. Such considerations gain importance at the time of COVID 19 pandemic, where a conservative management and an early discharge may be preferred owing to in-hospital morbidity after abdominal surgery whenever surgery may be avoided. METHODS AND RESULTS: We present a case of an OT successfully treated in a non-operative manner during COVID-19 outbreak in Norhern Italy and offer a review of the literature that supports such a clinical attitude.  Conclusions:  OT preoperative diagnosis is challenging and is usually achieved by abdominal CT-scan. The suggested OT initial management is conservative, leaving a surgical approach, preferably by laparoscopy, for the 15% of cases not improving with a non-surgical approach.

[Osteotomy in patellofemoral malalignment]. / Relevanz und Versorgung von Beinachsen- und Torsionsabweichungen bei chronischer Patellainstabilität.

Anterior knee pain and patellofemoral instability are the two major symptoms of patellofemoral dysbalance. Various pathologies can cause these symptoms. In recent years, axis deviations have been increasingly discussed as a cause of patellofemoral dysbalance. In the frontal axis, valgus deformities are a major risk factor, but torsional deformities may be a cause as well. Increased femoral internal rotation or increased tibial external rotation are the key pathologies. Osteotomy is the treatment of choice. Valgus deformities require varisation osteotomy, which is either performed on the femur or tibia depending on the location of the deformity. Torsional deformities are treated by external femoral or internal tibial torsional osteotomy. Femoral osteotomies are located above the femoral condyles, tibial osteotomies above the tibial tuberosity. Tibial internal torsional correction must not exceed 15° because this would jeopardise structures such as the peroneal nerve. Rehabilitation includes partial weight-bearing for four to six weeks. Hardware removal can be performed half a year after osteotomy. The relevance of axis deviations and treatment by osteotomy in patellofemoral dysbalance has been highlighted in recent reviews. Several publications report promising results after osteotomy, including significant pain relief and achievement of patellofemoral stability.

Asymptomatic autoamputation of ovary and fallopian tube in a 2 days newborn: a case report.

Automatic amputation of the ovary represents a rather uncommon condition. Especially asymptomatic autoamputation is an even more unusual laparoscopic finding. We hereby present a case of a 2-days´-old infant with a prenatal ultrasound (US) diagnosis of a cystic mass, laparoscopically proved as an amputated right adnexa. The female infant was asymptomatic and had normal laboratory exams, including hormone levels, according to her age. The infant was managed surgically, as the size of the cystic lesion, both prenatally and postnatally was indicative of surgical intervention. Careful monitoring is critical for the management of cystic lesions diagnosed prenatally. Although rare, the suspicion of an auto-amputated ovary has to be risen during diagnostic approach of infants with adnexal cysts, especially when these lesions are supposed to "wander" during imaging examinations, and also taking into account the size of the lesion in order for a final approach and management to be established.

Hepatic lobe torsion in 3 dromedary camels.

Hepatic lobe torsion is a rare condition in domestic animals. Clinical signs are variable, with some cases remaining subclinical and others resulting in death. Most cases are diagnosed either by laparotomy or during postmortem examination. During postmortem inspection of 670 slaughtered dromedary camels, hepatic lobe torsion of the quadrate lobe was detected in 3 adult female camels. Clinical signs had not been noted on antemortem veterinary inspection, and hepatic lobe torsion was likely an incidental finding. Histologically, the affected liver lobe exhibited severe hepatocellular loss with replacement by fibrous connective tissue. When investigating abdominal pain in camels, veterinarians should include hepatic lobe torsion in the list of differential diagnoses.

Estimating umbilical cord flow resistance from measurements of the whole cord.

Measuring umbilical blood pressure in utero is challenging and for this reason non-invasive methods are required. However, the total vessel blood pressure drop can be estimated using numerical and empirical results by studying the mechanics of fluids in coiled and straight tubes. Two key findings emerge from such an analysis. Firstly, the total pressure drop along a vessel at a given blood flow-rate depends on both the tightness of the coils and the total cord length. Relatively short and straight cords exhibit low pressure, while long, tightly coiled cords with large width exhibit high pressure. It follows that an estimate of the pressure requires three measurements: the full cord length, its average width and number of coils. Using this result we propose two prototype indices for clinical testing that estimate umbilical cord flow resistance. The umbilical pressure index (PX) and flow index (QX) quantify the deviation of a cord geometry from defined typical conditions by considering the steady pressure drop and flow-rate, respectively. These indices can be quickly calculated, and require only a single additional measurement to the conventional umbilical coiling index (UCI); namely the cord coiling width. Unlike the UCI, these indices are derived from blood-flow properties and provide a measure of the relative flow-resistance inherent to a cord geometry. Furthermore, the pressure index can be applied to irregularities, including loose true knots, which we show must be accounted for.

Management of adnexal masses' torsion during pregnancy.

With the increased use and quality of ultrasound in pregnancy, adnexal masses are being encountered with greater frequency. Most of the time such masses are asymptomatic. It can be discovered in an emergency. Surgical intervention may cause risks to the mother and her fetus, while observation without intervention may also lead to unfavorable complications, such as ovarian torsion or the development of a tumor. Therefore, the management requires a balance between the maternal and fetal risks. We report two cases of torsion of adnexal masses during pregnancy, and we provide a brief literature review on the management and prognosis of this condition in pregnancy.

Distal femoral morphological dysplasia is correlated with increased femoral torsion in patients with trochlear dysplasia and patellar instability.

AIMS: The purpose of this study was to explore the correlation between femoral torsion and morphology of the distal femoral condyle in patients with trochlear dysplasia and lateral patellar instability. METHODS: A total of 90 patients (64 female, 26 male; mean age 22.1 years (SD 7.2)) with lateral patellar dislocation and trochlear dysplasia who were awaiting surgical treatment between January 2015 and June 2019 were retrospectively analyzed. All patients underwent CT scans of the lower limb to assess the femoral torsion and morphology of the distal femur. The femoral torsion at various levels was assessed using the a) femoral anteversion angle (FAA), b) proximal and distal anteversion angle, c) angle of the proximal femoral axis-anatomical epicondylar axis (PFA-AEA), and d) angle of the AEA-posterior condylar line (AEA-PCL). Representative measurements of distal condylar length were taken and parameters using the ratios of the bianterior condyle, biposterior condyle, bicondyle, anterolateral condyle, and anteromedial condyle were calculated and correlated with reference to the AEA, using the Pearson Correlation coefficient. RESULTS: The femoral torsion had a strong correlation with distal condylar morphology. The FAA was significantly correlated with the ratio of the bianterior condyle (r = 0.355; p = 0.009), the AEA-PCL angle (r = 0.340; p = 0.001) and the ratio of the anterolateral condyle and lateral condyle (ALC-LC) (r = 0.309; p = 0.014). The PFA-AEA angle was also significantly correlated with the ratio of the bianterior condyle (r = 0.319; p = 0.008), the AEA-PCL angle (r = 0.231; p = 0.031), and the ratio of ALC-LC (r = 0.261; p = 0.034). In addition, the bianterior condyle ratio showed a significant correlation with the biposterior condyle ratio (r = -0.324; p = 0.027) and the AEA-PCL angle (r = 0.342; p = 0.021). CONCLUSION: Increased femoral torsion correlated with a prominent anterolateral condyle and a shorter posterolateral condyle compared with the medial condyle. The deformities of the anterior and posterior condyles are combined deformities rather than being isolated and individual deformities in patients with trochlear dysplasia and patella instability.

Susceptibility-weighted MR sequence for the evaluation of ovarian masses with torsion.

OBJECTIVE: Adnexal torsion is a rare gynecologic emergency caused by twisting of an adnexal mass. Twisted vascular pedicle is the most specific imaging finding for adnexal torsion, however, identification of twisted vascular pedicle can be challenging. The purpose of this study is to evaluate the feasibility of susceptibility-weighted MR sequence (SWS) for the diagnosis of adnexal torsion. METHODS: MR imaging including SWS (SWAN: susceptibility-weighted angiography) of surgically proven four benign ovarian masses with torsion (one acute and three subacute to chronic torsions) were retrospectively evaluated. Three cystic masses and one solid mass were included in this study. RESULTS: High signal intensity venous thrombus within the twisted vascular pedicle on T1-weighted imaging (T1WI) was detected in three lesions with subacute to chronic torsion (75%) but not in one lesion with acute torsion, whereas susceptibility-induced signal voids within the twisted vascular pedicle on SWAN were detected in all four lesions (100%). CONCLUSION: The demonstration of venous thrombus in the twisted vascular pedicle by SWS may be diagnostic for adnexal torsion. ADVANCES IN KNOWLEDGE: SWS can detect blood products sensitively and can reveal venous thrombus in the twisted vascular pedicle, which may be helpful for the diagnosis of adnexal torsion.

Internal tibial torsion is related to syndesmosis injury in a large osteological collection.

BACKGROUND: The long-term consequences of tibial torsion remain unclear. This study evaluated whether syndesmotic injuries are associated with tibial torsion. METHODS: A collection of over 3000 cadaveric skeletons was screened for irregular bony prominence along the lateral distal tibia, consistent with previous syndesmosis injury. Tibial torsion was measured and compared to 1034 control cadaveric tibiae. RESULTS: Mean torsion of 236 specimens with syndesmotic injury was 6.2±8.9 degrees, while that of control specimens was 7.9±8.8 degrees (P = 0.008). Multiple regression analysis showed a non-statistically significant trend toward internal torsion and syndesmotic injury (standardized beta=-0.051, P=0.059). Syndesmosis injury was present in 48/200 specimens (24.0%) with internal torsion and 31/199 specimens (15.6%) with external torsion (P=0.035). CONCLUSION: This association between internal tibial torsion and syndesmotic injury suggests that internal tibial torsion might not be an entirely benign condition and merits further study.

Umbilical cord hypercoiling in two rhesus macaques (Macaca mulatta).

Obstruction of umbilical blood flow is a common cause of death in fetal nonhuman primates, but cord accidents have not been reported in the macaque. We describe two cases of cord accident in rhesus macaques (Macaca mulatta) resulting in fetal death at approximately 110 and 50 days of gestation, respectively.

CT findings in five dogs with surgically confirmed colonic torsion.

Colonic torsion is a life-threatening condition that results in colonic ischemia, necrosis, perforation, sepsis, and eventual death. The aim of this multicenter, retrospective case series study was to describe the CT findings in dogs with surgically confirmed colonic torsion. Medical records were searched for dogs with surgically confirmed colonic torsion following abdominal CT. Five dogs met the inclusion criteria. Three had a history of chronic intermittent diarrhea prior to presentation. Two dogs presented with acute vomiting, diarrhea, and abdominal pain and one dog presented with acute vomiting and lethargy. Computed tomographic findings in all dogs with surgically confirmed colonic torsion include: "whirl sign," displacement and distension of the cecum and colon, focal narrowing of the colon, and distension of the mesenteric vasculature in all dogs (5/5); streaky peritoneal fat and peritoneal effusion (4/5), pneumatosis coli (2/5), small intestinal distension (2/5), portal vein thrombosis (1/5), and reduced colonic wall contrast enhancement (1/5). In all dogs (5/5), the torsion site was the descending colon and demonstrated an anticlockwise rotation. At surgery, three of the five dogs had a partial colonic torsion with hyperemia at the site of obstruction and two of the five dogs had a complete torsion with marked necrosis of the colonic wall. Displacement of the colon and cecum, segmental distension and focal narrowing of the colon, the presence of a "whirl sign" and distension of the mesenteric vasculature are CT findings highly suggestive of colonic torsion.

Protective effect of dipeptidyl peptidase-4 inhibitors in testicular torsion/detorsion in rats: a possible role of HIF-1α and nitric oxide.

Spermatic cord torsion is a serious and common urologic emergency. It requires early diagnosis for prevention of subfertility and testicular necrosis. Vildagliptin and sitagliptin are anti-diabetic drugs of the dipeptidyl peptidase-4 (DPP-4) inhibitors that have a protective role against cerebral ischemic stroke and cardiac ischemia reperfusion. This study aimed to investigate the role and mechanism of action of vildagliptin and sitagliptin in a model of testicular ischemia/reperfusion injury by testicular torsion/detorsion (T/D). Testicular T/D was done and vildagliptin and sitagliptin were administered either alone or in combination with nitric oxide synthase (NOS) inhibitor. Serum total cholesterol and testosterone were measured, while in testicular tissue testosterone, malondialdehyde (MDA) level, total antioxidant capacity (TAC), nitric oxide level, caspase-3, superoxide dismutase (SOD), hypoxia-inducible factor-1α (HIF-1α), tumor necrosis factor-α (TNF-α) and endothelial NOS (eNOS), and inducible NOS (iNOS) and neuronal NOS (nNOS) were measured. Histopathology of testicular tissue was done. Vildagliptin and sitagliptin increased serum testosterone, expression, and activity of SOD and testicular TAC. It also reduced total serum cholesterol, testicular MDA, caspase-3, HIF-1α, TNF-α, and expression of eNOS, iNOS, and nNOS. Vildagliptin and sitagliptin also improved histopathological picture of testicular tissue. NOS inhibitor produced similar result to DDP-4 inhibitors; however, its co-administration augmented the effect of vildagliptin and sitagliptin on these parameters. DPP-4 inhibitors, vildagliptin, and sitagliptin were protective against testicular T/D-induced injury mostly by anti-oxidative stress, and anti-apoptotic and anti-inflammatory actions that was augmented by NOS inhibition with a possible role for HIF-1α expression.

Adnexal Torsion in Pregnancy Managed by Laparoscopy Is Associated with Favorable Obstetric Outcomes.

STUDY OBJECTIVE: Most cases of adnexal torsion in pregnancy are currently managed by laparoscopy, which may be associated with increased risks for spontaneous abortion and preterm delivery. We sought to evaluate the obstetric outcomes of these women, with emphasis on their live birth rate and gestational age at delivery. DESIGN: Retrospective cohort study and telephone questionnaire. SETTING: University-affiliated obstetrics and gynecology department. PATIENTS: All pregnant women who underwent laparoscopy for adnexal torsion between 2007 and 2017. Their obstetric outcomes were obtained by retrospective review of medical records and a telephone questionnaire. INTERVENTIONS: Laparoscopy for adnexal detorsion, with or without cyst drainage or cystectomy. MEASUREMENTS AND MAIN RESULTS: The study cohort included 94 women. Most torsion cases (71, 75.5%) were diagnosed in the first trimester of pregnancy, whereas 21 (22.3%) cases and 2 (2.1%) cases were diagnosed in the second and third trimesters, respectively. Conception was achieved by in vitro fertilization or by ovulation induction in 45 (47.9%) cases. The information on pregnancy outcomes was available for 93 women. Of those, live birth was reported for 86 (92.5%) pregnancies, while 6 (6.5%) women had a spontaneous abortion, and 1 woman experienced an intrauterine fetal death. Five cases of spontaneous abortion were diagnosed in the first trimester, all within 3 weeks of surgery. Preterm delivery before 37 gestational weeks was reported for 18 (19.4%) pregnancies and was significantly associated with twin pregnancy (p = .002) and with conception following in vitro fertilization and ovulation induction (p = .03). On logistic regression analysis, preterm delivery was only associated with twin vs singleton gestation (odds ratio, 6.7; 95% confidence interval, 1.3-34.8; p = .02). CONCLUSION: The obstetric outcomes of pregnant women who underwent laparoscopy for adnexal torsion are generally favorable. However, there is a risk for preterm delivery, which is primarily associated with multiple gestations.
