Diagnostic performance of a modified O-RADS classification system for adnexal lesions incorporating clinical features.

PURPOSE: To compare the diagnostic efficacy of the Ovarian-Adnexal Reporting and Data System (O-RADS) MRI score with that of the modified O-RADS score on the basis of a simplified contrast-enhanced (CE) MRI protocol in characterizing adnexal masses with solid tissue. The added value of clinical features was evaluated to improve the ability of the scoring system to classify adnexal masses. METHODS: A total of 124 patients with 124 adnexal lesions containing solid tissue were included in this two-center retrospective study. Among them, there were 40 benign lesions (40/124, 32.3%) and 84 were malignant lesions (84/124, 67.7%). Three radiologists independently reviewed the images and assigned the O-RADS MRI score and the modified O-RADS score for each adnexal mass. Histopathology was used as the reference standard. The diagnostic efficacy of the two scoring methods was compared. Univariate and multivariate logistic regression were performed to evaluate the value of significant features in the prediction of malignant tumors. RESULTS: The O-RADS MRI score and modified O-RADS score showed sensitivity at 100.0% (95% CI, 95.7-100.0%) and 71.4% (95% CI, 60.5-80.8%), specificity at 12.5% (95% CI, 4.2-26.8%) and 75.0% (95% CI, 58.8-87.3%), respectively. The area under the curve of the modified O-RADS score was higher than the O-RADS score (0.732 [95% CI, 0.645-0.808] vs 0.575 [95% CI, 0.483-0.663]; p < 0.001). Multivariate analysis showed that the modified O-RADS score 4b or 5 combined with patient age > 38.5 years, nullipara, maximum diameter > 40.5 mm and HE4 > 78.9 pmol/L significantly improved the diagnostic efficacy up to 0.954 (95% CI, 0.901-0.984) (p < 0.001). CONCLUSION: A modified O-RADS score combined with certain clinical features can significantly improve the diagnostic efficacy in predicting malignant tumors.

Is It Possible to Prevent Nontherapeutic Laparotomies in Breast Cancer Patients With Isolated Adnexal Masses?

Introduction: The risk of ovarian malignancy is increasing in patients with a history of breast cancer. Thus, well-defined predictors of ovarian malignancy should be identified to determine surgical or conservative management of adnexal masses in women with breast cancer. This study aimed to clarify the predictors of malignant ovarian tumors in patients with breast cancer with an isolated adnexal mass. Methods: Breast cancer patients diagnosed with an adnexal mass who underwent surgery between 2010 and 2021 at a tertiary cancer center were included in the study. Patients with suspected extra ovarian metastases were excluded. Results: A total of 40 breast cancer patients who underwent surgery for ovarian masses were identified. 23 (57.5%) women had benign ovarian tumors and 17 (42.5%) had malignant ovarian tumors. Among the malignant ovarian tumors, there were three (17.6%) metastatic breast cancers in the ovary and 14 (82.4%) primary ovarian cancers. In univariate analyses, the risk of malignant ovarian tumors increased in women with age >52 years (P = .012), postmenopausal status (P = .023), CA 125 ≥ 35 IU/ml (P = .001), CA 15-3 ≥ 32 IU/ml (P = .002), and complex ovarian masses (P < .001). Ovarian malignancies were observed in 82.4% of patients who had complex ovarian masses. Conclusion: Ovarian malignancies were diagnosed in 82.4% of the breast cancers who had complex ovarian mass on USG examination. Therefore, surgery is recommended in women with complex ovarian masses. Postmenopausal status, age >52 years, CA 125 ≥ 35 IU/ml, and CA 15-3 ≥ 32 were other risk factors for ovarian malignancy.

Do we more often opt for conservative management of ovarian tumors after changing the Dutch national guideline on enlarged ovaries? A nationwide cohort study.

INTRODUCTION: Increasing evidence shows that conservative management of ovarian tumors classified as benign, based on ultrasound assessment, is safe. Therefore, conservative management has been adopted as the preferred strategy for certain ovarian tumors assessed as benign in the Dutch national guideline on enlarged ovaries in 2013. The aim of this study was to examine whether implementation of this guideline has led to changes in the number of women/100 000 women undergoing surgery for an ovarian tumor in the Netherlands. MATERIAL AND METHODS: Histopathology reports were requested for all examinations of ovarian and fallopian tube specimens (including cyst enucleations) registered in Palga, the Dutch nationwide pathology databank, from 2011 (before guideline adaptation) and 2019 (after guideline adaptation). Reports on prophylactically removed adnexa, removal for other primary tumors (e.g., endometrial carcinoma), and for patients under 18 years of age, were excluded from the analysis. Interobserver agreement for the inclusion and classification of reports was assessed using Cohen's Kappa analysis. RESULTS: A total of 34 932 reports were retrieved, 13 917 of which were included in the analysis. In 2011 and 2019, respectively, 96.3/100 000 versus 68.8/100 000 women aged ≥18 underwent surgery for benign ovarian tumors, and 19.6/100 000 versus 18.3/100 000 for borderline and malignant tumors combined. The number of women/100 000 who had surgery for a benign ovarian tumor per 100 000 women declined by 28.5% (p < 0.001) between 2011 and 2019. The largest difference between 2011 and 2019 was observed in the number of women per 100 000 women who underwent surgery for a serous cystadenoma (-40.7%; 20.8/100 000 vs. 12.3/100 000), followed by endometrioma (-33.2%; 14.7/100 000 vs. 9.8/100 000), simple epithelial cyst (-57.3%; 8.4/100 000 vs. 3.6/100 000), and corpus luteum cyst (-57.0%; 4.0/100 000 vs. 1.7/100 000). Cohen's Kappa for the interobserver agreement was 0.96. CONCLUSIONS: The number of women/100 000 undergoing surgery for a benign ovarian tumor has substantially decreased in the Netherlands when comparing data before and after implementation of the national guideline in 2013, while the number of women/100 000 undergoing surgery for a malignant or borderline tumor remained the same. These findings suggest successful implementation of the updated guideline, and a measurable effect on increased adoption of conservative management for benign-looking ovarian tumors.

Prospective external validation of IOTA methods for classifying adnexal masses and retrospective assessment of two-step strategy using benign descriptors and ADNEX: a Portuguese multicenter study.

OBJECTIVE: This study aimed to externally and prospectively validate the International Ovarian Tumor Analysis (IOTA) Simple Rules (SRs), Logistic Regression model 2 (LR2) and Assessment of Different NEoplasias in the adneXa (ADNEX) in a Portuguese population, comparing them with operator subjective assessment (SA), Risk-of-Malignancy Index (RMI), as well as with each other. This study also aimed to retrospectively validate IOTA two-step strategy, using modified benign descriptors (MBDs) followed by the application of ADNEX in cases where MBDs were not applicable (MBDs + ADNEX). METHODS: In this multicenter diagnostic accuracy study, conducted between January 2016 and December 2021, three tertiary referral centers prospectively included consecutive patients with ultrasound diagnosis of at least one adnexal tumor who underwent surgery. All ultrasound assessments were performed by level II or III sonologists with IOTA certification. Patient clinical data and serum cancer antigen (CA125) levels were collected from the hospital databases. Each adnexal mass was classified as benign or malignant using SA, RMI, IOTA SRs, LR2 and ADNEX (with and without CA125). The reference standard was histopathological diagnosis. In the second phase, all adnexal tumors were retrospectively classified using the two-step strategy (MBDs + ADNEX). The sensitivity, specificity, positive (PPV) and negative predictive value (NPV), positive (LR+) and negative likelihood ratio (LR-) as well as overall accuracy were determined for SA, RMI, IOTA SRs, LR2, ADNEX and two-step strategy (MBDs + ADNEX). Receiver-operator characteristic curves were constructed and corresponding areas under the curve (AUC) determined for RMI, LR2 and ADNEX and two-step strategy (MBDs + ADNEX). The ADNEX calibration plots were constructed and estimated by LOESS smoother. RESULTS: Of the 571 included patients, 428 had benign disease, 42 borderline ovarian tumors, 93 primary invasive adnexal cancers and 8 metastatic tumors in adnexa (malignancy prevalence: 25.0%). The operator SA had an overall sensitivity of 97.9% and a specificity of 83.6% for distinguishing between benign and malignant lesions. RMI showed high specificity (95.6%) but very low sensitivity (58.7%), with an AUC of 0.913. The IOTA SRs were applicable in 80.0% of patients, with a sensitivity of 94.8% and a specificity of 98.6%. LR2 revealed a sensitivity of 84.6%, a specificity of 86.9% and an AUC of 0.939, at the malignancy risk cut-off of 10%. At the same cut-off, ADNEX with and without CA125 had a sensitivity of 95.8% and 98.6%, respectively, and a specificity of 82.5% and 79.7%, respectively. The AUC of ADNEX with vs. without CA125 was 0.962 vs. 0.960. The ADNEX model provided heterogeneous results in distinguishing between benign and different subtypes of malignancy, with the highest AUC (0.991) for discriminating benign masses from primary adnexal cancer stage II-IV, and the lowest AUC (0.696) for distinguishing primary adnexal cancer stage I and metastatic lesion in adnexa. The ADNEX calibration plots suggested an underestimation of the predicted risk in relation with the observed proportion of malignancies. The MBDs were applicable in 26.3% of cases (150/571 tumors, none of which were malignant). Similar to the ADNEX model applied in all patients, the two-step strategy using ADNEX in the second step only, with and without CA125, had an AUC of 0.964 and 0.961, respectively. CONCLUSIONS: Our results showed a good to excellent performance of the IOTA methods in the studied Portuguese population, outperforming RMI. ADNEX was superior in accuracy, but interpretation of its ability to distinguish malignant subtypes was fundamentally limited not only by sample size but also by large differences in the prevalence of tumor subtypes. The IOTA MBDs have been shown to be reliable in identifying benign disease. The two-step strategy based on the application of MBDs, followed by the ADNEX model if MBDs are not applicable, has proven to be suitable for daily practice circumventing the need to use electronic support in all patients.

Effect of two different laparoscopic techniques on post-operative wound complications in patients with benign gynaecological diseases: A meta-analysis.

Single-port laparoscopy (SPL) has existed for several years. This meta-analysis was conducted to evaluate the efficacy of SPL compared with conventional laparoscopy (CL) in the treatment of benign gynecologic adnexal lesions. The purpose of this meta-analysis is to evaluate the superiority of SPL versus CL in the treatment of post-operative wound pain. The study looked for English-language publications from PubMed, Embase, Cochrane Library and the Web of Science until June 2023. The main result was the visual analogue scale (VAS) after 2, 4, 6, 8, 12, 24 and 48 h after operation. The paper contains 10 related papers by means of e-search. Of these, 4 were randomized controlled trials (RCTs), while 6 were non-RCTs. The results indicated that SPL and CL were significantly different after 2, 24 and 48 h after operation. SPL had lower post-operative pain after 2 h compared with CL (MD, -0.6; 95% CI, -0.98, -0.21; p = 0.002). After the operation, SPL also had a lower incidence of post-operative pain after 24 h compared with CL (MD, -0.59; 95% CI, -1.12, -0.06; p = 0.03). And the difference in pain was at 48 h after the most significant (MD, -0.49; 95% CI, -0.75, -0.23; p = 0.0002). But after 6, 8 and 12 h after operation, there was no significant difference in the degree of pain. Thus, SPL operations may result in a lower degree of pain than CL in both the post-operative and far post-operative phase.

Efficacy of a continuous wound infiltration system for postoperative pain management in gynecologic patients who underwent single-port access laparoscopy for adnexal disease.

Introduction: Single-port access (SPA) laparoscopy requires only one incision, unlike conventional laparoscopy. However, its umbilical incision is larger than that of conventional laparoscopy and can be vulnerable to postoperative pain. This study aimed to evaluate whether simultaneous use of a continuous wound infiltration (CWI) system and intravenous patient-controlled analgesia (IV PCA) effectively decreases surgical site pain in patients who underwent SPA laparoscopy due to gynecologic adnexal disease. Methods: A total of 371 patients who underwent SPA laparoscopy and who received IV PCA or CWI was retrospectively reviewed (combined group [CWI + IV PCA, n = 159] vs. PCA group [IV PCA only, n = 212]). To evaluate postoperative pain management, the numeric rating scale (NRS) pain score after surgery, total amount of fentanyl administered via IV PCA, and additional pain killer consumption were collected. Results: The NRS scores at 12 h (1.90 ± 1.11 vs. 2.70 ± 1.08, p < 0.001) and 24 h (1.82 ± 0.82 vs. 2.11 ± 1.44, p = 0.026) after surgery were significantly lower in the combined group than in the PCA group. The total amount of PCA fentanyl was significantly smaller in the combined group than in the PCA group (p < 0.001). The total quantity of rescue analgesics was smaller in the combined group than in the PCA group (p < 0.05). Conclusion: Combined use of the CWI system and IV PCA is an effective postoperative pain management strategy in patient who underwent SPA laparoscopy for adnexal disease.

Clinical Significance of the Combination of Serum HE4 Levels, Hemoglobin-to-Red Cell Distribution Width Ratio, and CT Imaging for the Pretreatment Assessment of Adnexal Masses.

Background: This study aimed to determine the optimal combination of biomarkers that can predict epithelial ovarian cancer (EOC) and compare the combination with the risk of ovarian malignancy algorithm (ROMA) or Copenhagen index (CPH-I). Methods: Data from 66 patients with EOC and 599 patients with benign ovarian masses who underwent definitive tissue diagnosis of adnexal masses between January 2017 and March 2021 were analyzed. The Mann-Whitney U test or Kruskal-Wallis test was used for between-group comparisons of medians. Logistic regression was used to establish an EOC predictor model. Area under the curve (AUC) comparisons between models were performed using the Delong nonparametric approach. Results: The median age of the patients was 43 years. Twenty-nine (43.9%) patients had early-stage disease (stages I-II) and 37 (56.1%) patients had advanced-stage disease (stages III-IV). The median age, body mass index, white blood cell count, hemoglobin-to-red cell distribution width ratio (HRR), platelet count, platelet-to-lymphocyte ratio, lymphocyte-to-monocyte ratio, serum albumin level, cancer antigen 125, human epididymal secretory protein 4 (HE4), ROMA, and CPH-I were significantly different between the stage I-IV EOC and benign ovarian mass groups. Multivariate logistic regression analysis revealed that HE4, HRR, and computed tomography (CT) imaging were significant predictors of both stages I-IV and I-II EOC. Using these covariates, an interim model (IM) (consisting of HE4 and HRR) and a full model (FM) (consisting of HE4, HRR, and CT imaging) were constructed. When predicting stage I-IV EOC, the AUC of IM was comparable to that of ROMA or CPH-I, whereas the AUC of FM outperformed ROMA or CPH-I. In predicting stage I-II EOC, the AUC of IM was comparable to that of CPH-I but higher than that of ROMA, and the AUC of FM outperformed ROMA or CPH-I. Conclusion: FM outperformed ROMA or CPH-I in predicting stage I-IV EOC and stage I-II EOC. Therefore, FM could be a promising model for improving preoperative prediction of EOC at an early stage. However, further prospective studies are required to validate these results.

Diagnostic imaging of adnexal masses in pregnancy.

Adnexal masses detected during pregnancy require a prompt and accurate diagnosis to ensure fetal safety and good oncological outcomes. Computed tomography is the most common and useful diagnostic imaging modality for diagnosing adnexal masses; however, it is contraindicated in pregnant women because of the teratogenic effect of radiation on the fetus. Therefore, ultrasonography (US) is commonly used as the main alternative for the differential diagnosis of adnexal masses during pregnancy. Additionally, magnetic resonance imaging (MRI) can assist in the diagnosis when US findings are inconclusive. As each disease has characteristic US and MRI findings, understanding these features is important for the initial diagnosis and subsequent treatment. Thus, we thoroughly reviewed the literature and summarized the key findings of US and MRI to apply these in real-world clinical practice for various adnexal masses detected during pregnancy.

How to improve O-RADS MRI score for rating adnexal masses with cystic component?

OBJECTIVES: To test the performance of the Ovarian-Adnexal Reporting Data System (O-RADS) MRI in characterizing adnexal masses with cystic components and to test new specific MRI features related to cystic components to improve the ability of the O-RADS MRI score to stratify lesions according to their risk of malignancy. METHODS: The EURopean ADnexal study (EURAD) database was retrospectively queried to identify adnexal masses with a cystic component. One junior and 13 radiologists independently reviewed cases blinded to the pathological diagnosis. For each lesion, the size of the whole lesion, morphological appearance, number of loculi, presence of a thickened wall, thickened septae, signal intensity of the cystic components on T1-weighted/T2-weighted/diffusion weighted, mean value of the apparent diffusion coefficient, and O-RADS MRI score were reported. Univariate and multivariate logistic regression analysis was performed to determine significant features to predict malignancy. RESULTS: The final cohort consisted of 585 patients with 779 pelvic masses who underwent pelvic MRI to characterize an adnexal mass(es). Histology served as the standard of reference. The diagnostic performance of the O-RADS MRI score was 0.944, 95%CI [0.922-0.961]. Significant criteria associated with malignancy included an O-RADS MRI score ≥ 4, ADCmean of cystic component > 1.69, number of loculi > 3, lesion size > 75 mm, the presence of a thick wall, and a low T1-weighted, a high T2-weighted, and a low diffusion-weighted signal intensity of the cystic component. Multivariate analysis demonstrated that an O-RADS MRI score ≥ combined with an ADC mean of the cystic component > 1.69, size > 75 mm, and low diffusion-weighted signal of the cystic component significantly improved the diagnostic performance up to 0.958, 95%CI [0.938-0.973]. CONCLUSION: Cystic component analysis may improve the diagnosis performance of the O-RADS MRI score in adnexal cystic masses. KEY POINTS: • O-RADS MRI score combined with specific cystic features (area under the receiving operating curve, AUROC = 0.958) improves the diagnostic performance of the O-RADS MRI score (AUROC = 0.944) for predicting malignancy in this cohort. • Cystic features that improve the prediction of malignancy are ADC mean > 1.69 (OR = 7); number of loculi ≥ 3 (OR = 5.16); lesion size > 75 mm (OR = 4.40); the presence of a thick wall (OR = 3.59); a high T2-weighted signal intensity score 4 or 5 (OR = 3.30); a low T1-weighted signal intensity score 1, 2, or 3 (OR = 3.45); and a low diffusion-weighted signal intensity (OR = 2.12). • An adnexal lesion with a cystic component rated O-RADS MRI score 4 and an ADC value of the cystic component < 1.69 associated with a low diffusion-weighted signal, has virtually a 0% risk of malignancy.

Variations in the management of adolescent adnexal torsion at a single institution and the creation of a unified care pathway.

PURPOSE: Adnexal torsion is a gynecologic emergency, requiring intervention for tissue preservation. At our institution, torsion is managed by pediatric surgeons or gynecologists. We evaluated differences between specialties to streamline evaluation for children with gynecological emergencies, develop a clinical pathway, and prevent care delays. METHODS: A retrospective review of adolescents undergoing intervention for adnexal torsion from 2004-2018 was performed. Differences in time to intervention, operation duration, the procedure performed, and length of stay (LOS) between the specialties were analyzed. RESULTS: Eighty-six patients underwent 94 operations for presumed adnexal torsion with 87 positive cases. Pediatric surgeons performed 60 operations and 34 cases were performed by gynecologists. Preservation of fertility was the goal in both cohorts and the rate of oophoropexy, cystectomy, and oophorectomy were similar between the cohorts (p = 0.14, p = 1.0, p = 0.39, respectively). There was no difference in intra-operative time (p = 0.69). LOS was shorter in the gynecology cohort (median 1 day [1-2] vs. 2 days [2-3], p > 0.001). CONCLUSIONS: Adnexal torsion is a time-sensitive diagnosis requiring prompt intervention for ovarian or fallopian tube preservation. A multidisciplinary institutional care pathway should be developed and implemented.

Can preoperative complete blood count parameters be used in the diagnosis of patients with adnexal torsion: a case-control study.

OBJECTIVE: To determine whether there is a relationship between complete blood count parameters at adnexal torsion and to investigate the clinical utility of these parameters in preoperative diagnosis. METHODS: The retrospective, case-control study was conducted at a tertiary care hospital in Turkey and comprised data of patients who underwent adnexal torsion surgery from 2007 to 2017. Medical records of healthy controls who underwent various gynaecological surgeries during the period were used as the control group. Demographic characteristics and preoperative complete blood count parameters were retrieved from the medical records, and factors influencing adnexal torsion diagnosis were evaluated. Data was analysed using SPSS 21. RESULTS: Of the 296 subjects, 73(24.7%) were adnexal torsion cases and 223(75.3%) were controls. Demographic characteristics did not differ between the groups (p>0.05). Leukocytosis was present in 38(52%) cases. Mean white blood cell, neutrophil, and platelet counts and neutrophil-to-lymphocyte and platelet-to-lymphocyte ratios were significantly higher, and mean platelet volume was significantly lower in the cases compared to controls (p<0.05). Logistic regression analysis identified an independent association between a low mean platelet volume and adnexal torsion (p<0.05). The optimal cutoff value was 10.35fL, with 77.4% sensitivity and 74.2% specificity. CONCLUSIONS: There was found to be a significant relationship between adnexal torsion and certain parameters of the complete blood count. Low mean platelet volume could be considered a useful additional tool for the preoperative diagnosis.

Effect of bupivacaine versus lidocaine local anesthesia on postoperative pain reduction in single-port access laparoscopic adnexal surgery using propensity score matching.

OBJECTIVE: The umbilicus is a single, painful incisional site on the abdomen during trans-umbilical single-port access laparoscopic surgery. Previously, we found that periumbilical lidocaine could reduce postoperative pain. This study aimed to compare the efficacy of bupivacaine and lidocaine in reducing pain. METHODS: We performed a retrospective analysis in a study group (Bupivacaine group, 100 patients who received periumbilical infiltration of bupivacaine before their incisional site repair completion) and control group (Lidocaine group, 100 patients who received lidocaine at their incisional site repair completion). We compared postoperative pain based on the numerical rating scale (NRS) between propensity score-matched Bupivacaine-treated (n=50) and Lidocaine-treated (n=50) patients. RESULTS: The postoperative pain scores based on the NRS were not significantly different between the 2 groups until 12 hours post-operation. However, 24 hours post-operation, the Bupivacaine group showed significantly lower pain than the Lidocaine group (24 hours, 1.76±1.07 vs. 2.53±1.11 NRS, P<0.001; 48 hours, 0.84±0.85 vs. 2.16±0.85 NRS, P<0.001). CONCLUSION: Periumbilical infiltration of bupivacaine has a longer acting efficacy on reducing postoperative surgical pain than that of lidocaine.

Hybrid Laparoendoscopic Single-Site Surgery Using a 2-mm Mini-Laparoscopic Instrument versus Conventional Three-Port Laparoscopy for Gynecologic Adnexal Diseases: A Prospective Randomized Trial.

BACKGROUND: Despite the advantages of laparoendoscopic single-site surgery (LESS), it has certain limitations that include longer surgical time, larger incision, and instrument collision. OBJECTIVE: To overcome these limitations, we incorporated a suprapubic 2-mm needle forceps into our hybridized LESS (hLESS) and evaluated its efficacy for benign adnexal disease in comparison with three-port laparoscopy (TPL). METHODS: This prospective study included 61 women randomly assigned in a 1:1 ratio. Incisions of 12 and 2 mm were made, respectively, at the umbilicus and suprapubic areas for hLESS. The length of surgery was compared. Postoperative pain was evaluated using a visual analog scale score, and consumption of analgesics. Cosmetic outcomes were assessed using a modified Vancouver Scar Scale and a body image questionnaire. RESULTS: The length of surgery was found to be similar. The pain score 2-h postoperatively was significantly less in the hLESS group. The scar impact from the hLESS was significantly more favorable compared to that from the TPL. The patients in the hLESS group had a significantly better perception of their body image. CONCLUSION: Despite the reduced umbilical incision size and the absence of specialized instruments required in LESS, the hLESS revealed a similar surgical time, lower postoperative pain, and a better cosmetic outcome compared to TPL.

Periumbilical infiltration of lidocaine with epinephrine for postoperative pain reduction in single-port laparoscopic adnexal surgery.

An efficient and simple approach to control postoperative pain in transumbilical single-port laparoscopic surgery appears necessary. We conducted a retrospective analysis in a study group (80 patients who received periumbilical infiltration of lidocaine with epinephrine before their incisional site repair completion) and control group (80 patients who received no analgesic at their incisional site repair completion) matched for their age, body mass index and their frequency of previous abdominal surgery. The pain scores based on the numerical rating scale (NRS) and the analgesic use frequency during the postoperative period were evaluated. The postoperative pain scores based on the NRS were significantly lower in the study group than in the control group immediately after the operation and at postoperative 6 hours. The postoperative analgesic use frequency during the hospital stay and the pain scores at 24 and 48 hours were not significantly different between the two groups. Periumbilical infiltration of lidocaine with epinephrine can reduce surgical pain until 6 hours, postoperatively. Impact statement What is already known on this subject? No consensus on whether single port laparoscopic surgery significantly reduces postoperative pain, as compared to conventional laparoscopy exists, and the immediate postoperative pain seems to be severe even with the SPL surgery. What do the results of this study add? The periumbilical infiltration of lidocaine with epinephrine can alleviate surgical pain until 6 hours, postoperatively. What are the implications of these findings for clinical practice and/or further research? Our result may provide an efficient and simple approach to control postoperative pain in a single port laparoscopic surgery.

Giant multiple and bilateral presacral Tarlov cysts mimicking adnexal mass - imaging features.

Perineural or Tarlov cysts (TCs) are nerve root cysts. They are usually incidental findings on MRI and are most frequently observed in the sacral spine. A 49-year-old woman presented with lower abdominal discomfort for several months. Physical examination demonstrated a cyst-like mass. An ultrasonographic examination revealed a cystic mass near the right ovary. MRI (3-Tesla unit) showed multiple, bilateral, and almost symmetric giant TCs with presacral space and endopelvic extension and minime scalloping. TCs originated from the right and left L5, S1, S2, and S3 nerve root sleeves entered the presacral space and extended into the pelvis.

Single-Port Laparoscopy vs Conventional Laparoscopy in Benign Adnexal Diseases: A Systematic Review and Meta-Analysis.

Single-port laparoscopy (SPL) was developed approximately 30 years ago in minimally invasive surgery. Literature comparing SPL with conventional laparoscopy (CL) for adnexal surgery (i.e., cystectomy and adnexectomy) is inconsistent. The objective of this systematic review and meta-analysis was to evaluate the advantage of SPL over CL for adnexal surgery. PubMed, Embase, and MEDLINE were searched for publications in English and in French published between 1975 and November 2015 using the following key words: (((single port) or (single site) or (one port) or (single-port access laparoscopy) or (single-site laparoscopy) or (laparoscopic single-site surgery)) and ((adnexal disease) or (ovarian cystectomy) or (ovariectomy) or (adnexectomy))) not (pregnancy). The primary outcome was postoperative pain assessed at 24 hours postsurgery. The secondary outcomes were postoperative pain at 6 and 48 hours postsurgery, analgesic consumption, operative time, blood loss, laparotomy conversion rate, mean hospital stay, and cosmetic results at 1 month. Sixteen relevant articles were identified by electronic search. The pooled analysis of randomized trials showed no significant difference between SPL and CL in terms of postoperative pain at 6 and 24 hours, blood loss, mean length of hospital stay, cosmetic results, and laparotomy conversion rate; however, operative time was longer for SPL (p = .03). The pooled analysis including all the selected studies showed no significant difference for all of these outcomes. This review and meta-analysis found no significant difference between SPL and CL for adnexal surgery, except for operative time. Further large-scale randomized trials should be conducted to investigate the potential advantages of SPL over CL before this laparoscopic approach can be recommended.

Simple descriptors and simple rules of the International Ovarian Tumor Analysis (IOTA) Group: a prospective study of combined use for the description of adnexal masses.

OBJECTIVE: External validation of the IOTA group's three-step diagnostic model (Strategy 1) and comparison with assessment by an expert sonographer (Strategy 2). STUDY DESIGN: Prospective study in patients with persistent adnexal masses, in which an inexperienced sonographer performed transvaginal ultrasound applying simple descriptors (SD) and rules (SR) for classifying as benign or malignant. Any non-classifiable mass was then submitted to an expert examiner for subjective assessment (SA). RESULTS: Eighty-one patients (mean age, 43; 27.2% postmenopausal) were included in this prospective study. Surgery was performed for 30 (8 malignant and 22 benign) masses; 51 masses were considered as benign and managed expectantly (they were assumed to be benign for statistical purposes). Diagnostic performance for Strategy 1 (SD+SR+SA) was sensitivity (SN): 87.5% (7/8, 95% CI, 47.3-99.7%) and specificity (SP): 100% (73/73, 95% CI, 95.1-100%). For Strategy 2 (SA only) it was SN 87.5% (7/8, 95% CI, 47.3-99.7%), SP 98.6% (72/73, 95% CI, 92.6-100%). CONCLUSIONS: The three-step diagnostic strategy designed by the IOTA group for adnexal masses has a diagnostic performance comparable to that of subjective expert assessment and could be used as a triage method by nonexpert sonographers.

Laparoscopic Outcomes for Pelvic Pathology in Children and Adolescents among Patients Presenting to the Pediatric and Adolescent Gynecology Service.

STUDY OBJECTIVE: The aim of this study was to evaluate surgical indications, outcomes, and common pelvic pathologies presenting to the Pediatric and Adolescent Gynecology service in premenarcheal (PMF) and menarcheal females (MF) undergoing laparoscopic surgery. DESIGN: A retrospective chart review. SETTING: An academic children's hospital. PARTICIPANTS: Females under 21 years of age, excluding pregnant patients, who underwent laparoscopic surgery for a gynecologic indication presenting to the Pediatric and Adolescent Gynecology service at a single children's hospital between July 2007 and January 2012, identified by CPT codes. MAIN OUTCOME MEASURES: Pertinent patient demographics, indication for surgery, anesthesia time, estimated blood loss, surgical instruments used, intra-operative findings, surgical pathology, complications, length of stay, and concerns at follow-up appointment. Descriptive statistics and chi-square analyses of data were performed using SAS 9.3. RESULTS: Of 158 cases meeting inclusion criteria, 33 patients were PMF (mean age 8.6 ± 3.2 years) and 125 patients were MF (mean age 14.7 ± 2.3 years). Acute abdominal pain was the most common surgical indication in both groups, but was significantly more likely to be the surgical indication in the PMF group (62.7% vs. 52.8%, P = .006). Adnexal torsion was more likely to be present in the PMF group than in the MF group (66.7% vs. 27.2%, P < .0001). No complications were reported in the PMF group. Two minor complications were reported in the MF group. CONCLUSION: Minimally invasive surgical techniques represent a safe and well-tolerated method for treating a wide variety of pelvic pathology in both younger children and older adolescent females. For physicians evaluating premenarcheal females with acute-onset abdominal pain, adnexal torsion should be prominent among the differential diagnoses.
