Main Recommendations: 1. Primary investigation of polypoid lesions of the gallbladder should be with abdominal ultrasound. Routine use of other imaging modalities is not recommended presently, but further research is needed. In centres with appropriate expertise and resources, alternative imaging modalities (such as contrast-enhanced and endoscopic ultrasound) may be useful to aid decision-making in difficult cases. Strong recommendation, low-moderate quality evidence. 2. Cholecystectomy is recommended in patients with polypoid lesions of the gallbladder measuring 10 mm or more, providing the patient is fit for, and accepts, surgery. Multidisciplinary discussion may be employed to assess perceived individual risk of malignancy. Strong recommendation, low-quality evidence. 3. Cholecystectomy is suggested for patients with a polypoid lesion and symptoms potentially attributable to the gallbladder if no alternative cause for the patient's symptoms is demonstrated and the patient is fit for, and accepts, surgery. The patient should be counselled regarding the benefit of cholecystectomy versus the risk of persistent symptoms. Strong recommendation, low-quality evidence. 4. If the patient has a 6-9 mm polypoid lesion of the gallbladder and one or more risk factors for malignancy, cholecystectomy is recommended if the patient is fit for, and accepts, surgery. These risk factors are as follows: age more than 60 years, history of primary sclerosing cholangitis (PSC), Asian ethnicity, sessile polypoid lesion (including focal gallbladder wall thickening > 4 mm). Strong recommendation, low-moderate quality evidence. 5. If the patient has either no risk factors for malignancy and a gallbladder polypoid lesion of 6-9 mm, or risk factors for malignancy and a gallbladder polypoid lesion 5 mm or less, follow-up ultrasound of the gallbladder is recommended at 6 months, 1 year and 2 years. Follow-up should be discontinued after 2 years in the absence of growth. Moderate strength recommendation, moderate-quality evidence. 6. If the patient has no risk factors for malignancy, and a gallbladder polypoid lesion of 5 mm or less, follow-up is not required. Strong recommendation, moderate-quality evidence. 7. If during follow-up the gallbladder polypoid lesion grows to 10 mm, then cholecystectomy is advised. If the polypoid lesion grows by 2 mm or more within the 2-year follow-up period, then the current size of the polypoid lesion should be considered along with patient risk factors. Multidisciplinary discussion may be employed to decide whether continuation of monitoring, or cholecystectomy, is necessary. Moderate strength recommendation, moderate-quality evidence. 8. If during follow-up the gallbladder polypoid lesion disappears, then monitoring can be discontinued. Strong recommendation, moderate-quality evidence., Source and Scope: These guidelines are an update of the 2017 recommendations developed between the European Society of Gastrointestinal and Abdominal Radiology (ESGAR), European Association for Endoscopic Surgery and other Interventional Techniques (EAES), International Society of Digestive Surgery-European Federation (EFISDS) and European Society of Gastrointestinal Endoscopy (ESGE). A targeted literature search was performed to discover recent evidence concerning the management and follow-up of gallbladder polyps. The changes within these updated guidelines were formulated after consideration of the latest evidence by a group of international experts. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) system was adopted to define the strength of recommendations and the quality of evidence., Key Point: • These recommendations update the 2017 European guidelines regarding the management and follow-up of gallbladder polyps., (© 2021.

Objective: To investigate the effect of hysteroscopy surgery combined with Mirena on postoperative adverse reactions and recurrence rate of endometrial polyps (EP)., Methods: A total of 312 patients who underwent hysteroscopic polypectomy of EP in our hospital from June 2017 to November 2020 were enrolled retrospectively. Among them, 42 patients did not take any treatment after the operation (control group), 156 patients were treated with levonorgestrel intrauterine birth control system (Mirena group), and 114 patients were treated with oral spironolone ethinylestradiol tablets (oral group). The clinical data of 312 patients were recorded and followed up regularly. All patients were followed up through an outpatient clinic or telephone to 12 months after the operation. The patients' age, disease course, number of pregnancies, clinical manifestations, endometrial thickness before the operation, duration of operation, amount of bleeding during the operation, and number and size of polyps were analyzed. The recurrence and postoperative side effects of EP in the three groups were followed up within 12 months after the operation., Results: There was no significant difference in endometrial thickness among the three groups before treatment ( P > 0.05). After 3 months, 6 months, and 12 months of treatment, the endometrial thickness of the three groups decreased, while the decrease in the Mirena group and the oral group was better compared to the control ( P < 0.05). The decrease in the Mirena group was better than that in the oral group ( P < 0.05). There was no significant difference in hemoglobin levels among the three groups before treatment ( P > 0.05). After 3, 6, and 12 months of treatment, the hemoglobin levels of the three groups increased to varying degrees, while the levels of the Mirena group and oral group were better compared to the control ( P < 0.05). Three months after the operation, the improvement of clinical symptoms was similar in the three groups, and there was no significant difference among the three groups ( P > 0.05). At 6 and 12 months after the operation, the improvement of clinical symptoms in the oral group and Mirena group was better compared to the control group ( P < 0.05), but there was no significant difference between the oral group and Mirena group ( P > 0.05). After the operation, some patients had complications such as lower abdominal pain, breast distension pain, irregular vaginal bleeding, and abnormal liver function. There was no significant difference in the number of complications among the three groups ( P > 0.05). During the follow-up to 12 months after the operation, the recurrence rate in the oral group and Mirena group was lower compared to the control ( P < 0.05), and the recurrence rate in the Mirena group was lower than that in the oral group ( P < 0.05)., Conclusion: Placing Mirena immediately after hysteroscopic polypectomy of EP can reduce the recurrence rate of endometrial polyps, increase the level of hemoglobin, and reduce the thickness of the endometrium, which can be employed and popularized according to the condition of patients in clinical work., Competing Interests: The authors declare that they have no conflicts of interest., (Copyright © 2022 Yanli Shen et al.)

Background: The overall clinical significance of the finding of endometrial abnormalities in predicting premalignant/malignant endometrial lesions is still incompletely determined. For this reason the management, surgical or expectant, of women in which an endometrial abnormality has been detected is debated., Methods: This retrospective study was carried out on 1020 consecutive women, 403 premenopausal and 617 postmenopausal, who underwent operative hysteroscopy in a University Hospital for suspected endometrial abnormalities, which were detected by transvaginal ultrasound (TVS) and/or office hysteroscopy. In these women, the clinical characteristics and findings at TVS and hysteroscopy were evaluated in relation to the presence/absence of premalignant/malignant endometrial lesions at pathology report., Results: The clinical characteristics considered were significantly different when the study women were compared according to their menopausal status. Premalignant/malignant lesions were found in 34/1020 (3.33%) women. Complex hyperplasia with atypia and endometrial cancer were detected in 22 (2.15%) and 12 (1.17%) cases, respectively. The postmenopausal women had a significantly higher risk of premalignant/malignant lesions than premenopausal women (O.R. = 5.098 [95% C.I.: 1.782-14.582], P < 0.005). This risk was even higher when abnormal uterine bleeding (AUB) was present (O.R. = 5.20 [95% C.I.: 2.38-11.35], P < 0.0001). The most significant associations with premalignant/malignant endometrial lesions were BMI, AUB in postmenopause, overall polyp size, atypical aspect of endometrial polyps at hysteroscopy, postmenopausal status, diabetes mellitus and patient age., Conclusions: The results of the present study suggest that the proper, aggressive or expectant, management of endometrial abnormalities should take into account both ultrasonographic and hysteroscopic findings together with the specific clinical characteristics of the patients., (© 2022.

Introduction: This study was designed to evaluate the feasibility and effectiveness of hysteroscopy in the management of symptoms related to endometrial polyps and submucous leiomyomas in women using a levonorgestrel-releasing intrauterine system (LNG-IUS)., Material and Methods: Twenty-three LNG-IUS users presenting with endometrial polyps and/or submucous leiomyomas and irregular uterine bleeding were recruited for hysteroscopic examination and surgery. Intrauterine pathology was investigated and treated by hysteroscopic resection with the LNG-IUS in situ , and the effect of the procedure on symptoms was evaluated after three to six months., Results: Intrauterine pathology was successfully resected by hysteroscopy in 23 (100.0%) out of 23 cases. Following hysteroscopy, 18 (78.3%) women reported amenorrhea, one (4.3%) regular spotting, three (13.0%) irregular spotting and one (4.3%) patient resumed normal menstrual cycle. We conclude that 19 (82.6%) patients were postoperatively asymptomatic. All procedures were uncomplicated and 4 (17.4%) were carried out without general anesthesia as office procedures., Conclusion: Endometrial polyps and submucous leiomyomas can develop in LNG-IUS users, and this can cause irregular uterine bleeding. Hysteroscopic resection of these pathologies is a feasible method in the clinical management of symptoms.

Background: With the increasing realization of the importance of gallbladder function, choledochoscopic gallbladder-preserving surgery has been advocated for benign gallbladder diseases. However, limited information is available regarding the use of endoscopic gallbladder-preserving surgery (EGPS) for patients with benign gallbladder diseases. The aim of this study was to evaluate the feasibility of EGPS for benign gallbladder diseases., Methods: Between June 2020 and January 2021, 22 patients with gallbladder stones and/or gallbladder polyps were treated with EGPS. The main outcome measures included the rate of complications, residual gallbladder stones, and gallbladder stone recurrence., Results: In this study, transgastric EGPS was successfully performed in 22 patients (13 female, 9 male) with benign gallbladder diseases, and included 8 cases of multiple gallstones, 4 cases of gallbladder polyps with gallstones, 6 cases of multiple gallbladder polyps, 2 cases of single gallstone, and 2 case of singe gallbladder polyp. The median time of transgastric EGPS was 118 min. During hospitalization, 4 patients suffered localized peritonitis (4/22, 18.2%), and these patients successfully recovered after conservative medical treatment. None of the patients experienced massive bleeding, delayed bleeding, diffuse peritonitis, or any other serious complications. During the median follow-up of 4 months, 1 patient suffered residual gallstone, while no gallstone recurrence or deaths related to transgastric EGPS occurred in any patients., Conclusions: Transgastric EGPS appears to be a feasible treatment method in selected patients with benign gallbladder diseases. However, as it is a new technique, further studies are needed to explore the long-term effectiveness of transgastric EGPS., (© 2022.

Background: Atypical polypoid adenomyoma (APA) is a rare intrauterine polypoid lesion that occurs predominantly in premenopausal women. Although APA was previously considered a benign lesion and treated conservatively, an increasing number of cases show that APA has a high rate of recurrence or residual disease and that it precedes the development of carcinoma. The clinical management of APA remains to be established. The aim of this study was to analyse the clinicopathological features of APA and discuss its diagnosis and prognosis., Methods: Forty-four patients with APA were admitted to Beijing Obstetrics and Gynecology Hospital from 2005 to 2019, and their clinical and histopathologic features were evaluated. B-ultrasound was performed, and all the patients (n = 44) underwent hysteroscopy. Endometrium excision was performed by means of the four-step diagnosis and treatment method. Hysteroscopic transcervical resection (TCR) was performed in 5 patients with APA-H and 11 with APA-L. Except for one patient who underwent transcervical endometrial resection, all the patients underwent hysterectomy and salpingectomy or salpingo-oophorectomy. Data from a median follow-up of 42 months (ranging from 3 to 174 months) were available for these patients., Results: Pathological diagnosis were made according to the degree of abnormality of the APA surface glands, resulting in APA-L in 36 patients and APA-H in 8 patients. Among these patients, 28 (25 APA-L and 3 APA-H) were treated conservatively. The effect of the four-step diagnosis and treatment method as an APA therapy was excellent. During the follow-up, no evidence of recurrence was found., Conclusions: For patients with intracavitary lesions > 1 cm, the hysteroscopic four-step diagnosis and treatment method and pathological diagnosis are the basis of clinical treatment. More than 30% of APA surface glands have complex structures characterized by branching and budding or other high-risk factors, such as endometrial hyperplasia, which are indications for hysterectomy. For patients who desire to become pregnant or to preserve the uterus, hysteroscopy with complete excision of the lesions should be the preferred treatment method. The patients should be treated and followed up closely with regular hysteroscopy and endometrial biopsy., (© 2022. The Author(s).)

The RNA-binding protein LIN28B is an important factor for cell proliferation. Because LIN28B polymorphisms have been shown to be relative with the recurrence of some hyperplastic diseases, we hypothesized that genetic variants of LIN28B gene were associated with postoperative recurrence risk in reproductive-age women with endometrial polyps (EP). In a hospital-based cohort of 351 reproductive female patients underwent hysteroscopic polypectomies between May 2018 and Jan 2020, we genotyped two common polymorphisms in LIN28B gene (rs369065 C > T and rs314280 A > G) and analyzed their associations with the risk of postoperative recurrence in multiple Cox regression model. When followed up to Jun 2021, carries of rs369065 TT genotype had an increased risk of polyp recurrence (adjusting hazard ratio [HR] = 1.883, 95% confidence interval [CI] = 1.033 - 3.434) and had a shorter time to recurrence (median time 352 vs. 342 days, log-rank P < 0.01), compared to the CC/CT genotype. Further stratification analysis showed that the increased risk of rs369065 TT genotype was more evident in patients who were older than 33 years (adjusted HR = 2.597, 95%CI = 1.037 - 6.505), had a single polyp (adjusted HR = 2.545, 95%CI = 1.059 - 6.113), and had smaller polyps (<1.2 cm, adjusted HR = 2.708, 95%CI = 1.042 - 7.043). However, no significant association between rs314280 A > G polymorphism and the risk of polyp recurrence was found. Our study suggests that rs369065 TT genotype of LIN28B gene is associated with an increased postoperative recurrence risk in EP patients, especially in those with fewer and smaller polyps. These findings implicate a precise choice of clinical counseling and decision making. Larger studies in different ethnic populations are warranted., Competing Interests: The authors declare that there are no conflicts of interest regarding the publication of this paper., (Copyright © 2022 Mei-Yin Lu et al.)

Background/aims: Gastric polyps (GPs) are usually asymptomatic lesions of the upper gastrointestinal tract observed in 1-3% of esophagogastroduodenoscopies (EGD). Most GPs are benign. The aim of this study was to precise the frequency of different types of gastric polyps in our population, and to analyze their possible association with other factors., Materials and Methods: A total of 18,496 consecutive patients undergoing EGD over a 10-year period (between 2007 and 2018) in a tertiary hospital were retrospectively reviewed. Eighty-six patients diagnosed with gastric polyps were analysed. Demographics, medical history of the patients, and indication for gastroscopy were collected. Morphological, histological characteristics of polyps, and therapeutic management data were also collected., Results: GPs were found in 86 out of 18,496 (0.46%) reviewed EGD, corresponding to a total of 141 polyps. There were 64 female (74.4%) and 22 male patients (25.6%) with a sex ratio (M/F) of 0.34. The average age was 58.1 years. One hundred and forty one polyps were included, and histopathology was obtained on 127 GPs. The most common location was the fundus (59.6%) and 48.9% were smaller than 5 mm. The polyp was unique in 75.6% of cases. According to Paris classification, 80% of the polyps were sessile (Is). Hyperplastic polyps were the most common (55.9%), followed by sporadic fundic gland polyps observed in 23 patients (18.1%), 7 (5.5%) were adenomas and 4 (3.1%) were neuroendocrine tumors type 1. The following factors were associated with hyperplastic polyps: anemia (p = 0.022), single polyp (p = 0.025) and size ≥ 5 mm (p = 0.048). Comparing hyperplastic polyps' biopsies to resected polyps, no difference was found in the evolutionary profile of the 2 groups. A size less than 10 mm (p = 0.013) was associated with fundic gland polyps. Sixty polyps (47.2%) were treated by cold forceps, 19 (15%) treated by a mucosal resection and 15 (11.8%) with diathermic snare. Five procedural bleeding incidents were observed (3.9%). Only the use of anticoagulant treatment was associated with a high bleeding risk (p = 0.005). The comparative histological study between specimens of biopsied GPs and endoscopic polypectomy led to an overall agreement of 95.3%., Conclusion: In our study, the GPs frequency was 0.36%. Hyperplastic polyps and fundic gland are the most common in our country. The high frequency of Helicobacter pylori infection in our patients and in our area may explain the high frequency of HP., (© 2022. The Author(s).)

Thanks to the progress of science, it is now understood that a successful implantation not only depends on the quality of the embryo, but also on having a receptive endometrium. During the years, several authors have reviewed the important role of the uterine factor, ranging from the congenital anomalies, such as uterine septa and subsepta, and acquired conditions such as endometrial polyps and submucous myomas. Currently, hysteroscopy has proved to be a powerful and accurate tool for visualizing the uterine cavity and treating intrauterine pathologies. This review of the literature aims to report the current available data on the effects of the two most common endouterine pathologies (i.e. endometrial polyps and submucous myomas) and the impact of hysteroscopic removal on fertility outcomes. To date, the low number of randomized controlled trials available does not yet make it possible to give a definitive answer on what are the reproductive outcomes following treatment of endometrial polyps and leiomyomas. Nevertheless, existing evidence points to a benefit of removal of these two pathologies in infertile women, mostly when they have a history of recurrent pregnancy loss. Further studies are needed to demonstrate that surgical treatments of endometrial polyps and myomas could improve not only the morphology but also the function of the uterine cavity before undergoing any assisted fertility treatment.

Here, we report a unique case in which a fibroepithelial polyp was found in the cartilaginous part of the external auditory canal of a 2-year-old child. The polyp was successfully treated by excision using an endaural approach and healed without complications. This is the very first report of a fibroepithelial polyp in the external auditory canal in the pediatric population. Although fibroepithelial polyp is an extremely rare diagnosis, it should be considered in the differential diagnosis of a child's external auditory canal polyp.

Background: Current management guidelines for gallbladder polyps (GBPs) focus on a diameter more than 1 cm as an indication for cholecystectomy. Since most GBPs are not malignant, unnecessary cholecystectomies can lead to unnecessary complications and costs. We developed a score to identify true polyps focusing on their cross-sectional area (CSA)., Methods: We retrospectively analyzed the demographic, clinical, laboratory, and sonographic characteristics of 522 patients with GBPs who had undergone cholecystectomy at our hospital between January 2010 and July 2020 (reference group). We used univariate analysis to compare these parameters between 88 true polyps and 434 pseudopolyps and multivariate logistic regression analysis to identify parameters to include in our scoring model. Receiver operating characteristics and area under the curve were used to identify cut-off values. The model was tested on a validation group of 98 patients., Results: In the multivariate analysis, a CSA >123 mm 2 , positive blood flow signal, age >55.5 years, alanine aminotransferase (ALT) levels > 50 U/L, and an ALT/aspartate aminotransferase ratio > 0.77 were significantly associated with true polyps (odds ratio 6.528, 2.377, 2.617, 2.445, and -0.372, respectively). A prediction model based on cut-off values was used to distinguish a low-risk and high-risk GBP group; true polyps accounted for 6.54% and 58.72%, respectively (p < 0.001). In the low-risk and high-risk validation groups, true polyps comprised 12.35% and 82.35%, respectively (p < 0.001)., Conclusions: Our scoring system shows high accuracy and specificity in identifying true polyps and helps determine the need for surgical resection., Competing Interests: Declaration of competing interest The authors report no proprietary or commercial interest in any product mentioned or concept discussed in this article., (Copyright © 2021.

Gall bladder polyp is a lesion which is often an incidentally reported finding on ultrasonography. Such patients may or may not have symptoms of gall bladder disease. Although majority of polyps are cholesterol polyps, some are malignant. The challenge is early detection of malignant polyp and cholecystectomy before it becomes invasive or if invasive to carry out adequately wide surgical excision; while avoiding surgery in asymptomatic patients with benign disease. Following are the characteristics suggestive of malignancy in polyp: - size more than 10 mm, solitary lesions, increase in size over time, adenomatous polyps, sessile lesions and associated gallbladder wall thickening. Incidence of malignancy is higher in patients with Indian ethnicity, age more than 50 years, associated primary sclerosing cholangitis or gall stone disease. Pre-operative tissue diagnosis is difficult to obtain and review ultrasonography, contrast enhanced CT scan, endo sonography and a regular follow-up can help the surgeon take the appropriate decision., (© Journal of the Association of Physicians of India 2011.)

Introduction: Controversy remains about the classification, differential diagnosis, and treatment strategy for gallbladder polypoid lesions (GPLs). This study sought to explore the individualized treatment strategy for GPLs., Methods: We retrospectively studied 642 consecutive patients with GPLs from January 2015 to May 2020. Univariate and multivariable analyses were performed to explore the potential risk factors for neoplastic polyps. The outcome of laparoscopic gallbladder-preserving polypectomy (GPP) was evaluated and compared with that of laparoscopic cholecystectomy (LC)., Results: Of 642 enrolled patients, 572 underwent LC, and 70 underwent GPP. Pathologically, the majority of GPLs were cholesterol polyps (68.4%), followed by adenomyomatosis (19.9%), benign adenoma (7.3%), adenocarcinoma (3.6%), and rare pathological types (0.8%). Additionally, 66.3% (379/572) of the LC cases were classified as non-neoplastic, and 33.7% (193/572) neoplastic polyps. Multivariate analysis demonstrated that single polyps (OR 1.956, 95% CI: 1.121-3.412; p = 0.018), polyps located at the gallbladder fundus (OR 4.326, 95% CI: 2.179-8.591; p < 0.001), polyps not less than 14 mm (OR 2.833, 95% CI: 1.614-4.973; p < 0.001), and polyps with a broad base (OR 4.173, 95% CI: 1.743-9.990; p = 0.001) were independent risk factors for neoplastic polyps. The 5-year prospective results after GPP showed that the 1-year and 3-year polyp recurrence rates were 13.2% and 23.4%, respectively., Conclusion: The majority of GPLs are cholesterol or other benign lesions without malignant potential. LC is the main treatment procedure for GPLs with a high neoplastic risk. GPP is potentially feasible and could be an alternative management strategy for a group of GPLs patients who meet the selection criteria., (© 2023 S. Karger AG, Basel.)

Objective: To investigate the effect of tissue pepsin expression of vocal polyps on the postoperative curative effect. Methods: Retrospectively analyze the data of 112 patients diagnosed with vocal cord polyps and undergone surgery from June 2019 to March 2021. The cases were divided into positive group and negative group according to the immunohistochemical pepsin expression. The preoperative reflux symptom index （RSI） and the reflux finding score （RFS） were compared, and the recovery of the voice acoustic function and postoperative vocal cord morphology were analyzed. Results: Among the postoperative specimens of 112 patients,76 cases were positive for pepsin staining, accounting for 67.9%, and 36 cases were negative, accounting for 32.1%. In the pepsin-positive group, 48 cases of vocal cord morphology returned to normal, and 20 cases remained scar or edema in the operation area, 8 cases of polyps relapsed; in the pepsin-negative group, a total of 32 cases of vocal cord morphology returned to normal, 4 cases of remained scar or edema in the operation area, no relapsed cases, the difference in vocal cord morphology recovery was significant （χ²=8.689, P =0.013）. The symptoms of hoarseness improved after 12 weeks. The differences between pre and post operative of G grade, VHI, MPT, fundamental frequency perturbation and amplitude perturbation assessed by GRBAS were significant （ P <0.05）; postoperative G grade, VHI, MPT, fundamental frequency perturbation and amplitude perturbation were compared between the pepsin-positive group and the pepsin-negative group, and the differences were significant （all P <0.05）. Conclusion: The expression of pepsin in vocal polyps is a significant clinical indicator that affects the acoustic effect and morphological recovery of vocal cords after surgery. For patients with positive expression, acid suppression treatment should be strengthened after surgery., Competing Interests: The authors of this article and the planning committee members and staff have no relevant financial relationships with commercial interests to disclose., (Copyright© by the Editorial Department of Journal of Clinical Otorhinolaryngology Head and Neck Surgery.)

Background: Polypoid lesion of gallbladder (PLG) size larger than 10 mm is considered to be one of the surgical indications, but the final pathological results are mostly non-neoplastic polyps. The aim of the study was to define the risk factors to discriminate neoplastic PLG and create more precise criteria for surgical indications., Methods: A large scale, case-series study based on 2704 patients who underwent cholecystectomy for PLG was designed. Logistic regression analysis and receiver operating characteristic curve (ROC) was adopted to identify risk factors and the optimal size criteria for predicting neoplastic PLG., Results: Patients in the neoplastic group were significantly older than those in the non-neoplastic group and the average PLG size is much larger in the neoplastic group (18.5 ± 4.7 mm vs 12.6 ± 3.6 mm). Neoplastic PLGs are prone to be single and non-neoplastic polyps are usually multiple. On Multivariate logistic regression analysis, PLG size larger than 15 mm and age older than 43 years were found to be the independent risk factors to discriminate neoplastic PLG （Odds ratio 3.546 and 2.77 respectively）. The ROC curve showed that 12 mm might be the more reasonable PLG size threshold for the surgical suggestion., Conclusions: Considering its moderate diagnostic accuracy, the size of gallbladder polyp larger than 10 mm is insufficient to indicate surgical therapy for PLG and 12 mm should be the more optimal polyp's size threshold. Patients older than 43 years have a higher risk of having neoplastic polyps., Competing Interests: Declaration of competing interest The authors declare that there are no conflicts of interest in this study., (Copyright © 2021.

Introduction: Polypoidal choroidal vasculopathy (PCV) is a vascular disease of the choroid. Diagnosis is mainly based on polypoidal aneurysm-like lesions seen in indocyanine green (ICG) angiography. Various therapeutic options have been proposed., Methods: Outcomes of 10 cases with extrafoveal PCV and consecutive macular edema treated with thermal laser are reported. Diagnosis of PCV was confirmed by ICG angiography., Results: Upon successful occlusion of the polyps in 10 eyes after thermal laser treatment demonstrated in ICG angiography, a regression of central foveal edema was seen in optical coherence tomography and color fundus photography. Visual acuity improved from logMAR 0.8 to logMAR 0.3. Follow-up ranged from 4 months to 15 years, with a median of 1 year. Two eyes had a recurrence of exudative maculopathy 5 and 7 years after laser treatment, respectively., Conclusion: A careful differentiation between various subforms of exudative maculopathy using fluorescein and ICG angiography can identify certain selected patients with extrafoveal PCV, for whom thermal laser monotherapy can be a therapeutic option., Competing Interests: The authors declare that they have no conflict of interest., (Thieme.

Introduction: To determine the prevalence of malignant lesions in endometrial polyps by hysteroscopic polypectomy, and risk factors for malignant transformation. The secondary aim was to evaluate background endometrium of atypical hyperplasia in endometrial polyps, and the risk of coexisting endometrial carcinoma after hysterectomy., Methods: This retrospective study included women who underwent hysteroscopic polypectomy between January 2015 and December 2019. Demographic characteristics, hysteroscopic findings, and histopathology results of the polyp and the uterus, in the case of a hysterectomy, were collected., Results: In all, 946 women were included in the study. Endometrial carcinoma in a polyp was found in 10 women (1.06%), and atypical hyperplasia was found in 11 women (1.16%). At the multivariate logistic regression model of risk factors, old age (P = 0.022) and obesity (P = 0.011) were significantly associated with (pre-)malignant polyp. Five of the ten women (50%) with atypical hyperplasia confined to a polyp had coexisting endometrial carcinoma in the hysterectomy specimen., Conclusion: Women with risk factors should be offered hysteroscopic polypectomy to allow a reliable histologic evaluation. Furthermore, hysterectomy is recommended in women with atypical hyperplasia in endometrial polyps even after complete resection., (© 2021 International Federation of Gynecology and Obstetrics.)

Background and Study Aims: Sporadic fundic gland polyps (FGP) are the most common type of gastric polyp, reported in 0.8%-1.9% of patients undergoing Esophagogastroduodenoscopy (EGD). Data on long-term outcomes of large FGP is limited. We aim to study the natural history of sporadic large (≥ 10 mm) FGPs., Patients and Methods: All adults who underwent EGD for any indication from April 2014 to December 2019 at a tertiary care center were retrospectively assessed, and patients with FGP (≥10mm) were identified. Data on baseline characteristics and long-term outcomes were recorded. Follow-up data were recorded for patients who underwent repeat endoscopy to evaluate for rates of dysplasia and cancer., Results: A total of 4,000 patients with a diagnosis of FGP were screened and 132 large, biopsy-proven FGPs were included in the final analysis. The most common indication for EGD was gastroesophageal reflux disease (61%). During a follow-up period of 3.2 years, the rate of dysplasia, was 4.0%. Subgroup analysis based on size (10-19 mm and ≥ 20 mm) showed no significant difference in overall outcomes., Conclusion: Repeat EGDs for surveillance should not be routinely performed since large (≥10 mm) sporadic FGPs are mostly benign without significant malignant potential.

Goals: Assess neoplasia and polypectomy-related adverse event (AE) rates in gastric hyperplastic polyps (GHPs)., Background: GHPs carry a risk of neoplastic transformation. The rate of neoplastic transformation and the risk of polypectomy-related bleeding are unclear in the West, as data are derived from Asian or small studies. The authors aimed to determine the rate of dysplasia and intraprocedural AEs in GHP polypectomies in a western cohort., Study: A retrospective study of 591 GHPs >1 cm resected in 491 patients in a single referral center on the occurrence of neoplasia and intraprocedural AEs., Results: The mean age was 74.9±11.1 years, 57% female individuals. The mean polyp size was 2±0.8 cm. There were 11 neoplastic polyps (1.9%) with low-grade dysplasia, high-grade dysplasia, and cancer in 7 (1.3%), 2 (0.3%), and 2 (0.3%), respectively. Neoplasia was associated with age [9 (3.2%) for more than 75 years vs. 2 (0.7%) for less than 75 years; P=0.035], but not with polyp size or gender. Fifty patients (8.5%) had intraprocedural bleeding (IPB) requiring endoscopic intervention, with 3 hospitalizations. There were no perforations or procedure-related deaths. IPB was associated with polyp size and neoplasia. The adjusted odds ratio (95% confidence interval) for IPB was 1.63 (1.2-2.2) for a 1 cm increase in polyp size, and 7.4 (1.9-29.6) for the presence of neoplasia., Conclusions: The neoplasia rate in GHPs was 1.9%, lower than most previous reports, with no major intraprocedural AEs. Physicians may consider biopsy and follow-up in frail elderly patients, but the safety of this strategy needs further confirmation., (Copyright © 2020 Wolters Kluwer Health, Inc.

Background: Currently, determining the postoperative recurrence of endometrial polyps is an unresolved issue, so we screened the risk factors to establish a nomogram for clinical practice., Methods: From January 2012 to June 2020, 133 patients who underwent hysteroscopic endometrial polypectomy and diagnostic curettage due to suspicious endometrial polyps for the first time and were pathologically diagnosed as endometrial polyps after surgery. All patients were followed up for more than 12 months, and 9 (6.77%) cases were lost to follow-up. Logistic regression analysis of clinical factors was performed to screen independent risk factors and construct a column chart to predict the probability of adverse events. The fitting curve was used to validate the line graph., Results: The ratio of patients with body mass index (BMI) <28 kg/m2 in the recurrence group was lower than in the non-recurrence group (P=0.028), as was the proportion of patients with polyp <2 cm (recurrence group vs. non-recurrence group, P=0.027) and the proportion of patients in the recurrence group treated with progesterone after surgery compared with non-recurrence group (P=0.003). However, the proportion of endometrial thickening in the recurrence group was higher than in the non-recurrence group (P=0.006). Age, BMI, polyp size, and endometrial thickening were independent risk factors for recurrence after endometrial polypectomy [odds ratio (OR) >1, P<0.05]. Progesterone therapy after surgery was an independent protective factor for recurrence after endometrial polypectomy (OR <1, P<0.05). Our nomogram was based on age, BMI, polyp size, endometrial thickening, and postoperative progesterone treatment. The maximum offset between the predicted curve and the ideal curve was 0.083, and the minimum offset between the model and the ideal model was 0.021. The height of the linear curve was close to that of the ideal curve. The U test showed P=0.898, greater than 0.05, indicating that the nomogram model passed the calibration test. The receiver operating characteristic curve was 0.886., Conclusions: Our nomogram based on age, BMI, polyp size, progesterone treatment, and endometrial thickening accurately predicted the risk of polyp recurrence after endometrial polypectomy and can be applied in clinical practice.

Purpose: To retrospectively review the multicenter outcome of patients with ureteral fibroepithelial polyps (UFPs) after endoscopic management with thulium laser. Materials and Methods: A total of 21 adult patients with UFPs were treated in three medical centers between May 2007 and June 2018. We performed ureteroscopy operation and resected the polyps with thulium laser. The Double-J stent was removed 6 weeks after surgery during the 11-year follow-up period. Thereafter, we conducted computed tomography urography (CTU) or ultrasonic checks every 3-6 months. Results: All patients had UFPs resected with thulium laser. The mean length of the UFPs was 3.4 ± 1.43 cm (range 1.8-6.9). They included 12 men and 9 women with a mean age of 41.91 ± 13.56 years. Unilateral polyps were observed in 20 patients (left: n  = 13; right: n  = 7), whereas 1 patient had bilateral polyps. Back pain was the main symptom (12, 57.14%) identified. The amount of bleeding and the mean surgery time was 8.43 ± 4.02 mL and 42.43 ± 13.53 minutes, respectively. The average length of stay was 4 days (a range of 3-6 days). Notably, no patient exhibited ureteral perforation. We did not observe an increase in hydronephrosis during the follow-up period, ultrasonography showed that it was attenuated 6 weeks later. Besides, 3 months later, CTU revealed favorable recovery without recurrence or ureterostenosis. Conclusions: Ureteroscopy operation combined with thulium laser resection is a minimally invasive and effective method for treating UFPs. Based on our limited multicenter research findings, thulium laser achieves favorable outcomes in restoring drainage from the kidney and reduces recurrence.

Objectives/hypothesis: To examine patterns of recurrence of benign phonotraumatic vocal fold lesions over time for insights into pathophysiology., Study Design: Case series with mathematical modeling., Methods: Medical records and stroboscopic exams of adults who underwent microlaryngoscopic resection of phonotraumatic vocal fold lesions over a 13-year period were reviewed for time to recurrence after surgery. Uniform and log-normal probability distributions were fitted to the time to recurrence curves for vocal fold polyps, midfold masses, and pseudocysts. Model fits were compared using the Akaike information criterion corrected, a standard measure of the goodness of fit. Stochastic simulations were used to verify that the mechanistic hypotheses were concordant with the selected probability distributions and empiric data., Results: Of 567 patients who underwent microlaryngoscopic resection, 65 had a recurrence (16 polyps, 14 midfold masses, and 35 pseudocysts). Midfold mass and pseudocyst recurrences were predominantly seen in younger women. Polyps were best fit by a uniform distribution rather than log-normal, whereas midfold masses and pseudocysts were better fit by log-normal rather than uniform. Stochastic simulations suggest that polyps recur sporadically according to a paroxysmal-developmental model, whereas midfold mass and pseudocyst recurrences follow a force-multiplication, damage-accumulation process., Conclusions: Vocal fold polyps are acute lesions evenly distributed by age and gender that recur uniformly over time, suggesting they arise from sudden tissue reactions to phonotraumatic stress. Pseudocysts and midfold fibrous masses are chronic lesions predominantly found in young women that recur with log-normal distribution over time, suggesting gradual damage accumulation in larynges predisposed to enhanced phonotrauma., Level of Evidence: 4 Laryngoscope, 131:2523-2529, 2021., (© 2021 The American Laryngological, Rhinological and Otological Society, Inc.)

Introduction and Aim: Endometrial polyps (EPs) are a common gynecologic condition, associated with abnormal uterine bleeding (AUB), infertility, and premalignant and malignant conditions. Technologies for diagnosis and treatment of EPs are constantly evolving. We aim to provide an updated review on diagnosis and management options for patients with EPs., Material and Methods: We conducted an electronic search in databases including MEDLINE, PubMed, Cochrane Central Register and others. We included 68 publications regarding EPs, their clinical burden, diagnostic modalities, treatment options and new technologies., Results: Transvaginal ultrasound (TVS) is the common modality for EP detection and color doppler increases its diagnostic accuracy. Dilation and curettage (D&C) should be avoided for diagnosis and treatment of EPs. Hysteroscopy shows high diagnostic value in EPs and allows for both histological diagnosis and effective treatment. Office hysteroscopy and see and treat hysteroscopy without anesthesia is feasible and safe for EP diagnosis and treatment, gaining more trained surgeons globally. Effective and safe technological tools for EP resection include Laser, resectoscopes, morcellators, MyoSure, Truclear and scissors\graspers., Conclusions: EPs are safely and effectively diagnosed and treated with the hysteroscopic tools reviewed in this article. More research is needed to define the best treatment modality.

There are different types of gallbladder polyps having variable morphology and nature. Symptoms are vague and mostly diagnosed incidentally on abdominal ultrasound. Risk factors are many. Indications of surgery are not clearly understood due to lack of clinical evidence. This study was carried out to analyze the management of gallbladder polyp in our settings and review of available evidence. Patients who underwent clip less mini laparoscopic cholecystectomy for gallbladder polyp were included. Clinical data including short history, age, gender, parity, lab tests, ultrasound report and macroscopy were recorded during surgery. Histopathology reports collected later. Total of 112 patients with mean age 42.6 years (range 22-82), 74 of whom were female. Most of them (46.42%) were asymptomatic. Single polyp was in 69, multiple in 32 and polyp with stone in 8 patients. Sessile polyp was 74.10%. Average polyp size was 7.6mm. Cholesterol polyp was in 82 patients. Four out of 5 malignant polyps were single and sessile. Abdominal ultrasound is the mainstay of diagnosis of gallbladder polyp but size, location, morphology, number and presence of associated gallstone has to be mentioned. Symptomatic gallbladder polyp benefited from surgery. Polyps more than 6mm, single and sessile morphology above the age 50 should undergo cholecystectomy.

Background: Fibroepithelial polyps located in the ureter constitute 2-6% of all benign tumors in the urinary system. Distinguishing these lesions from transitional cell carcinoma is essential to avoid unnecessary nephroureterectomy., Case Presentation: A 59-year-old asymptomatic caucasian male patient was enrolled in follow-up for Ta low-grade transitional cell bladder cancer 4 years ago in our clinic. A suspicious, solid, contrast-enhancing mass 15 × 9 mm in diameter in the anteromedial mid-section of the left kidney, which was causing minimal washout and largely located in the parenchyma, was reported as renal cell carcinoma on computed tomography during routine controls. In the excretory phase, soft-tissue densities of approximately 30 mm in length, which were located in the distal part of the left ureter at a distance of 40 mm from the ureterovesical junction, extending towards the lumen suggested a urethral carcinoma. Urothelial lesion was reported as fibroepithelial polyp after histopathological examination. Partial nephrectomy for the mass, which was reported as renal cell carcinoma in the left kidney, was performed in the first postoperative month. Histopathological examination revealed Fuhrman grade 1 papillary type renal cell carcinoma. No recurrence was observed in the first year after treatment., Conclusions: Although our patient had a bladder transitional cell carcinoma and a suspicious renal cell carcinoma mass of 15 mm in the ipsilateral kidney, the patient was safeguarded from unnecessary nephroureterectomy early on by cross-sectional and endoscopic imaging of the ureter., (© 2021.

Background: Regular membrane peeling vitrectomy for epiretinal membrane (ERM) patients seldom causes large pigment epithelial detachment (PED). We presented an unusual case of the activation of quiescent polypoidal choroidal vasculopathy (PCV) after membrane peeling vitrectomy for ERM, with an uneven therapeutic process., Case Presentation: A 75-year-old female patient complained of metamorphopsia in her left eye for 2 years. Her best-corrected visual acuity was 20/160 with a moderate nuclear cataract. An irregular ERM and slight PED were shown in optical coherence tomography (OCT). No obvious orange-red lesion was detected. The patient underwent vitrectomy + ERM peeling + cataract surgery. After the operation, large PED emerged, and indocyanine green angiography (ICGA) confirmed PCV. Four monthly injections of intravitreal ranibizumab were administered, but PED persisted. After focal laser therapy targeted to the polyps combined with ranibizumab treatment, PED was absorbed., Conclusions: Careful evaluation for PCV before membrane peeling vitrectomy for ERM is important, as indolent PCV may be activated postoperatively. Anti-VEGF therapy accompanied by laser photocoagulation may be more effective for PCV polyps located away from the fovea., (© 2021. The Author(s).)

Vocal fold polyp (VFP) is an exophytic gelatinous lesion with an atrophic epithelium. After behavioral and conservative management, phonomicrosurgery is the treatment of choice for VFPs with excellent outcomes in terms of lesion resolution and postoperative vocal function. Office-based potassium titanyl phosphate (KTP) laser ablation is a new treatment modality for VFPs but its efficacy for professional singers has yet to be validated. Reported is a consecutive series of six professional singers (with seven episodes of VFP) who, based on patient and provider preference, underwent in-office KTP laser ablation of VFP. Two polyps required two ablation procedures; otherwise, a single treatment was successful in resolution of VFP at a mean resolution time of 44 days. Singing voice handicap index 10 improved from a mean of 30.8 (range 4-40) to 6.0 (range 0-22). All patients resumed their professional singing careers without vocal limitations. Posttreatment videos were reviewed by three blinded fellowship trained laryngologists, who were not able to accurately predict the laterality of the polyp (52% correct, p = 0.99)., (Copyright © 2020 The Voice Foundation.

Background: Gallbladder polyps are relatively common. Although most gallbladder polyps are benign, some are malignant. Current guidelines state that malignancy should be suspected for polyps ≥ 10 mm in diameter. We clarified the cancer detection rates in accordance with the size distribution of gallbladder polyps, and evaluated the effectiveness of the reported risk factors in predicting malignancy., Methods: In this retrospective case-control study, our institutional database was searched to identify patients who underwent laparoscopic cholecystectomy for benign or malignant gallbladder polyps at Sada Hospital, Japan. The chi-squared test was used to analyze the risk factors for malignancy., Results: There were 227 protruding gallbladder lesions. The 206 benign polyps had a diameter of 2-21 mm, while the 21 malignant polyps were 7-60 mm. The cancer detection rates were 16.4% for lesions ≥ 10 mm, 55.9% for lesions ≥ 15 mm, and 94.1% for lesions ≥ 20 mm. Of the benign lesions, cholesterol polyps were the most frequent (50-100%) in all size ranges, even in large lesions (≥ 15 mm). The sessile lesion morphology was significantly more frequent in malignant (60%) than benign lesions (3.4%, p < 0.00001). Multiple polyps were frequently diagnosed not only as cholesterol polyps (81.1%), but also as adenomas (60%); adenomas were found as a single adenoma within other types of polyps. There were two cases of malignant small gallbladder polyps (< 10 mm); these lesions met the surgical indications of a size increase during observation or a sessile morphology., Conclusions: The cancer detection rate increased significantly with an increase in the lesion size. Risk factors such as a sessile polyp morphology or an increase in lesion size were effective in predicting malignancy for small gallbladder polyps. It might be difficult to accurately predict the pathologic diagnoses of gallbladder polyps preoperatively, as cholesterol polyps were most frequent, even in the large size range., (© 2020.

Background: Surgical indications for the treatment of gallbladder polyps are controversial. Evaluation of gallbladder polyps with malignant tendency and indications for cholecystectomy in patients with long diameter polyps of 10 to 15 mm require further analysis and discussion. In this study, our objective was to re-evaluate indications for the surgical resection of gallbladder polyps and construct a nomogram model for the prediction of gallbladder polyps with malignant tendency., Methods: Clinicopathologic data of 2,272 patients who had undergone cholecystectomy for gallbladder polyps were collected from 11 medical centers in China. Risk factor analyses and nomogram prediction model for gallbladder polyps with malignant tendency were conducted., Results: Excluding 311 patients with cholelithiasis and 488 patients with long diameter polyps ≤5 and >15 mm, factors that differed significantly among patients with gallbladder polyps having a long diameter of 6 to 9 mm (885 cases) and 10 to 15 mm (588 cases) were polyp detection time, CEA and CA19-9 levels, number of polyps, fundus, echogenicity, gallbladder wall thickness and postoperative pathologic features (P < .05). Among 588 patients with gallbladder polyps with a long diameter of 10 of 15 mm, multivariate analysis indicated the following independent risk factors of gallbladder polyps with malignant tendency: single polyps (OR = 0.286/P < .001), polyps with broad base (OR = 2.644/P = .001), polyps with medium/low echogenicity (OR = 2.387/P = .003), and polyps with short diameter of 7 to 9 or 10 to 15 mm (OR = 3.820/P = .005; OR = 2.220/P = .048, respectively). The C-index of the nomogram model and internal validation were .778 and .768, respectively. In addition, a sample online calculator for the nomogram prediction model had been created (https://docliqi.shinyapps.io/dynnom/)., Conclusion: Indications for cholecystectomy in patients with gallbladder polyps with a long diameter of 10 to 15 mm should be assessed by combining the information on short diameter, number of polyps, fundus, and echogenicity. The nomogram model can be used to predict the risk for the development of gallbladder polyps with malignant tendency., (Copyright © 2021 Elsevier Inc. All rights reserved.)
