Fibrovascular polyp is a rare non-epithelial esophageal tumor arising from submucosal layer and consisting of connective and adipose tissue, as well large number of vessels. Large tumors can cause dysphagia, vomiting, chest pain, shortness of breath and/or asthma, while giant neoplasms are potentially life threatening. Despite active introduction of minimally invasive treatment of patients with non-epithelial gastrointestinal tumors, there are still difficulties in surgical treatment of fibrovascular polyps. The patient with a giant fibrovascular esophageal polyp presented with cough, discomfort in the throat, impaired swallowing and episode of tumor migration into oropharynx. Examination confirmed giant highly vascularized esophageal fibrovascular polyp. A novel hybrid surgical technique (endoscopic submucosal dissection with laparoscopic removal of tumor) was applied. Eight-month follow-up revealed no complications. Favorable clinical result was achieved. A hybrid laparo-endoscopic approach in the treatment of patients with large fibrovascular polyps minimizes perioperative risks and improves postoperative outcomes.

Background and Aims: Endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD) are complementary techniques for large (≥20 mm) nonpedunculated rectal polyps (LNPRPs). A mechanism for appropriate technique selection has not been described., Methods: We evaluated the performance of a selective resection algorithm (SRA) (August 2017 to April 2021) compared with a universal EMR algorithm (UEA) (July 2008 to July 2017) for LNPRPs within a prospective observational study. In the SRA, LNPRPs with features of superficial submucosal invasive cancer (SMIC) (<1000 μm; Kudo pit pattern Vi), or with an increased risk of SMIC (Paris 0-Is or 0-IIa+Is nongranular, 0-IIa+Is granular with a dominant nodule ≥10 mm) underwent ESD. The remaining LNPRPs underwent EMR. Algorithm performance was evaluated by SMIC identified after EMR, curative oncologic resection (R0 resection, superficial SMIC, absence of negative histologic features), technical success, adverse events, and recurrence at first surveillance colonoscopy., Results: A total of 480 LNPRPs were evaluated (290 UEA, 190 SRA). Median lesion size was 40 (interquartile range, 30-60) mm. SMIC was identified in 56 (11.7%) LNPRPs. Significant differences in SMIC after EMR (SRA 1 [1.0%] vs UEA 35 [12.1%]; P = .001) and curative oncologic resection (SRA n = 7 [33.3%] vs UEA n = 2 [5.7%]; P = .010) were identified. No significant differences in technical success or adverse events were identified (all P > .137). Among LNPRPs with SMIC amenable to curative oncologic resection and which underwent ESD, 100% (n = 7 of 7) were cured., Conclusions: A rectum-specific SRA optimizes oncologic outcomes for LNPRPs and mitigates the risk of piecemeal resection of cancers., (Copyright © 2023 AGA Institute.

Background: It is important to identify gallbladder polyps (GPs) with malignant potential and avoid unnecessary cholecystectomy by constructing prediction model. The aim of the study is to develop a Bayesian network (BN) prediction model for GPs with malignant potential in a long diameter of 8-15 mm based on preoperative ultrasound., Methods: The independent risk factors for GPs with malignant potential were screened by χ 2 test and Logistic regression model. Prediction model was established and validated using data from 1296 patients with GPs who underwent cholecystectomy from January 2015 to December 2019 at 11 tertiary hospitals in China. A BN model was established based on the independent risk variables., Results: Independent risk factors for GPs with malignant potential included age, number of polyps, polyp size (long diameter), polyp size (short diameter), and fundus. The BN prediction model identified relationships between polyp size (long diameter) and three other variables [polyp size (short diameter), fundus and number of polyps]. Each variable was assigned scores under different status and the probabilities of GPs with malignant potential were classified as [0-0.2), [0.2-0.5), [0.5-0.8) and [0.8-1] according to the total points of [- 337, - 234], [- 197, - 145], [- 123, - 108], and [- 62,500], respectively. The AUC was 77.38% and 75.13%, and the model accuracy was 75.58% and 80.47% for the BN model in the training set and testing set, respectively., Conclusion: A BN prediction model was accurate and practical for predicting GPs with malignant potential patients in a long diameter of 8-15 mm undergoing cholecystectomy based on preoperative ultrasound., (© 2022.

Background: The identification of gastric polyps incidentally in endoscopies of the upper digestive tract has increased its incidence, varying between 0.5% and 23%. 10% of these polyps have symptoms, 40% are hyperplastic. We allow ourselves to propose a laparoscopic technique for the management of giant hyperplastic polyps associated with a pyloric syndrome, not susceptible to endoscopic resection., Method: A series of patients approached by laparoscopic transgastric polypectomy due to the giant gastric polyps associated with pyloric syndrome, in Bogotá, Colombia, from January 2015 to December 2018., Results: Seven patients, 85% female, with an average age of 51 years, who were admitted for pyloric syndrome and were taken to laparoscopic management, with an average surgical time of 42 min, intraoperative bleeding 7-8 cc, tolerance to the oral route 24 hours, no conversion, without mortality., Conclusions: Transgastric polypectomy for the management of benign giant gastric polyps that cannot be resected endoscopically turns out to be a feasible method, with a low rate of complications and without mortality., (Copyright: © 2023 Permanyer.)

Although uncommon, vaginal fibroepithelial polyps can present as prolapsing vaginal tissue, causing discomfort and anxiety. Surgical excision of the polyps can provide a minimally invasive solution. In this case, we describe a nulliparous female in late adolescence who presented for evaluation of tissue protruding through the vagina. On exam, a 5×4 cm fibroepithelial polyp was extending from the distal posterior vagina on a broad stalk. Successful transperineal surgical excision was performed. Fibroepithelial polyps, although uncommon, can be a cause for prolapsing vaginal tissue and should be part of the differential diagnosis, especially in patients who have no risk factors for pelvic organ prolapse. They can be excised vaginally, alleviating symptoms and distress. Because they sometimes recur, continued surveillance with gynaecological exams is recommended., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2022.

Background: Cervical polyps removed during pregnancy have been reported to be associated with preterm birth; however, the association between unremoved cervical polyps and preterm birth has not been elucidated., Objective: This study aimed to clarify the relationship between cervical polyps detected before 12 weeks of gestation managed expectantly and spontaneous preterm birth., Study Design: This retrospective cohort study included pregnant women who visited a tertiary perinatal center before 12 weeks of gestation between January 2015 and December 2019. The exclusion criteria were as follows: multiple gestations, loss or termination of pregnancy before 12 weeks of gestation, major fetal anomalies, fetal chromosomal abnormalities, fetal demise, having undergone removal of cervical polyps before the first visit to our hospital, and moving to other hospitals before delivery. A vaginal speculum examination was routinely performed during a prenatal visit before 12 weeks of gestation. When a cervical polyp was detected on speculum examination, it was managed expectantly, unless gynecologic malignancy was suspected. Relationships between cervical polyps and spontaneous preterm birth before 34 weeks of gestation were evaluated using logistic regression analysis and Cox proportional-hazards analysis adjusted for known confounders for spontaneous preterm birth., Results: A total of 4172 pregnant women were included, of whom 92 (2.2%) had a cervical polyp detected before 12 weeks of gestation. None of the women underwent polypectomy during pregnancy. The incidence of spontaneous preterm birth before 34 weeks of gestation was higher in pregnant women with cervical polyps than in those without them (5.4% vs 0.7%; P<.01). Logistic regression analysis revealed that cervical polyps were an independent risk factor for spontaneous preterm birth before 34 weeks of gestation (adjusted odds ratio, 4.09; 95% confidence interval, 1.70-9.81; P<.01). The adjusted hazard ratio for spontaneous preterm birth before 34 weeks of gestation among women with vs without cervical polyps was 2.95 (95% confidence interval, 1.32-6.62; P<.01)., Conclusion: Cervical polyps detected before 12 weeks of gestation managed expectantly are a significant risk factor for spontaneous preterm birth before 34 weeks of gestation., (Copyright © 2022 Elsevier Inc.

Background: To assess the efficacy of dysdrogesterone in the treatment of chronic endometritis (CE) treated with antibiotic in premenopausal women with endometrial polyps (EPs)., Methods: Routine detection of endometrium was simultaneously conducted to determine whether there was CE by syndecan-1 (CD138), while women underwent hysteroscopic polypectomy in our hospital. Antibiotic was given for the treatment of CE. A total of 235 premenopausal women with CE who underwent hysteroscopic polypectomy were enrolled in the retrospective observational study. In the control group, single antibiotic was given for the treatment of CE form January 2016 to December 2018, and in the treatment group additional dydrogesterone was used from January 2019 to November 2020. Comparison of cure rates of CE with different treatment regimens was performed., Results: The cure rates of CE in dydrogesterone and antibiotic combination group and the single antibiotic group were 85.2% and 74.3%, respectively, with overall cure rate of 80.0% (188/235). The combination group showed better effects regarding the cure rate of CE (P &lt; .05). Multivariate analysis confirmed that the cure rate of CE was not affected by age, body mass index, number of EPs, the status of estrogen receptor and the status of progesterone receptor. Conversely, dydrogesterone and endometrial scratching were beneficial factors for cure rate increase with antibiotic treatment., Conclusion: Combination of dydrogesterone and antibiotic was more effective for cure rate of CE than antibiotic alone in premenopausal women after hysteroscopic polypectomy. Endometrial scratching also contributed to the cure rate increase with antibiotic treatment., (© 2022. The Author(s).)

Objectives: To discover patterns of phonotraumatic lesions in singers and investigate factors that differentiate those who underwent surgery from those who did not. We hypothesized that 1) lesion type distribution differs by age, sex, singer classification (professional/amateur), and history of formal voice training; 2) the likelihood of surgery is associated with singer classification and voice training., Study Design: Retrospective., Methods: Retrospective review of 438 singers with phonotraumatic lesions over a 9-year period. Lesion type distribution was analyzed with respect to sex, age, singer classification, and voice training. The association of eventual surgery with these factors was also analyzed., Results: Nodules accounted for over half of the cohort (58%), followed by pseudocysts (20%), polyps (14%), and cysts (4%). Nearly two of every three injured female singers, but fewer than one out of every three injured male singers, had nodules. In contrast, over half of the injured males had polyps, whereas only 6% of injured females had polyps. In females, polyps occurred at a later age, and in males, nodules occurred at a younger age compared to other lesion types. Only 14% of the total cohort eventually underwent surgery. Professional singers without formal voice training were almost eight times more likely to have undergone surgery than amateur singers with voice training., Conclusions: Professional singers were more likely to undergo surgery than amateurs, and formal voice training was associated with a lower likelihood of surgery. The observation that polyps tended to occur in older women may have implications for the pathogenesis of vocal fold polyps., Level of Evidence: 4 Laryngoscope, 132:2180-2186, 2022., (© 2022 The American Laryngological, Rhinological and Otological Society, Inc.)

Introduction: Rectal malignant polyps can be managed by use of trans-anal resections (TAR). Traditional techniques of resection have been replaced by use of platforms such as trans-anal minimally invasive surgery (TAMIS) or trans-anal endoscopic microsurgery (TEM). This study reviewed the management of rectal malignant polyps, in particular focussing on when clinicians used TAR., Methods: A population wide cohort study of all malignant rectal polyps diagnosed in Queensland, Australia from 2011 to 2018 was undertaken. Patient and pathological factors were compared across the management strategies of polypectomy, TAR and rectal resection., Results: Overall 430 patients were diagnosed with a malignant rectal polyp during the study period, with 103 undergoing a TAR. There was increasing use of TAR across the study period as a management strategy (P < 0.001). Polypectomy alone was more likely to be the management strategy over TAR or rectal resection if there were clear margins (P < 0.001). The distance to the closest polypectomy margin was also significantly higher in the polypectomy group with mean clearance 2.09 mm in polypectomy group versus 0.86 mm in TAR group and 0.99 mm in resection group (P < 0.001). Rectal resection was more likely to be the management strategy over TAR if there was LVI (P < 0.001), depth of invasion was deeper (P < 0.001) and there was tumour budding (P = 0.001)., Conclusion: TAR is an effective management strategy for rectal polyps and is utilized particularly in rectal malignant polyps when there are close or involved margins. Future guideline development should consider incorporation of TAR given the advances in techniques afforded by TAMIS or TEM platforms., (© 2022 The Authors.

Aim: To evaluate the risk factors of miscarriage in patients attempted cervical polypectomy during the first and second trimester pregnancy., Methods: Pregnant women with singleton infants who underwent cervical polypectomy during the first and second trimester between January 2013 and May 2019 were investigated. The study retrospectively reviewed the clinical features and pregnancy outcomes after cervical polypectomy. A multivariable regression was performed to predict the risk factors of miscarriage., Results: A total of 307 pregnant females were eventually included in our study. Twenty-seven patients (8.8%, 27/307) had a miscarriage before 28 weeks, 37 patients (12.1%, 37/307) had a preterm delivery. After univariate analysis, we found that the presence of decidual polyps and vaginal bleeding after polypectomy were the risk factors for miscarriage. Moreover, the incidence of miscarriage was significantly higher in the patients with decidual polyps than in those with endocervical polyps (14.9% vs. 5.6%, p = 0.010)., Conclusions: The most suitable hemostasis method should be taken in the cervical polypectomy during pregnancy. The risk of miscarriage associated with polypectomy during pregnancy is higher in females with decidual polyps. If decidual polyps are highly suspected and they do not cause excessive vaginal bleeding and can be ruled out the possibility of malignancy, conservative treatment may lead to a better outcome., (© 2022 Japan Society of Obstetrics and Gynecology.)

Objective: To compare the safety and efficiency of hysteroscopic laser vaporesection and hysteroscopic resection in the treatment of endometrial polyps. Methods: The literatures in databases were searched comprehensively, the literatures that met the inclusion criteria were screened out and the data were extracted. The data were combined with Stata12.0 statistical software., Results: 4 literatures were included with a total sample size of 334. Meta-analysis showed that intraoperative blood loss in laser group was less than that in electrosurgical group [-3.043, 95% CI (-4.09, -2.00), P < 0.001]. Length of stay in the laser group was shorter than that in the electrotomy group [-1.013, 95% CI (-1.37, -0.65), P < 0.001]. The recurrence rate [0.275, 95%CI (0.135,0.563), P < 0.001] and complication rate [0.148, 95%CI (0.07,0.32), P < 0.001] in the laser group were lower than those in the electrotomy group. There was no significant difference in operative time between hysteroscopy combined with 2 μm laser and hysteroscopic electrotomy for endometrial polyps [-0.38, 95% CI (-1.34, 0.58), P = 0.441 > 0.05]., Conclusion: Hysteroscopic 2 μm laser vaporesection for the treatment of endometrial polyps has better safety and clinical efficacy. Compared with hysteroscopic electroresection, hysteroscopic laser vaporesection in the treatment of endometrial polyps may be safer and more effective. Given the potential limitations, we need larger, well-designed randomized controlled trials to verify our findings.

Background and Aim: gastric inflammatory fibroid polyps constitute only 0.1 % of all gastric polyps. They are usually amenable to resection by snare polypectomy. However, on rare occasions, these lesions may require resection by endoscopic submucosal dissection. This study aimed to evaluate the effectiveness and safety of endoscopic submucosal dissection in the management of gastric inflammatory fibroid polyps not amenable to resection with snare polypectomy., Methods: a retrospective observational study of all consecutive patients who underwent endoscopic submucosal dissection for gastric inflammatory fibroid polyps between January 2011 and December 2020 was performed., Results: there were nine cases of gastric inflammatory fibroid polyps resected by endoscopic submucosal dissection. Most patients were female (7/9) with a mean age of 62.2 years. All gastric inflammatory fibroid polyps were described as solitary antral subepithelial lesions with a mean diameter of 16.7 mm, which appeared well-circumscribed and homogeneous lesions located at muscularis mucosa and submucosa without deeper invasion on endoscopic ultrasound. All lesions were successfully resected by en bloc and complete resection with free margins obtained in 8/9 specimens. Adverse events were reported in 2/9 cases including one intra-procedural bleeding successfully controlled with hemostatic clips and one aspiration pneumonia that evolved favorably. Mean follow-up duration was 33.7 months and no delayed complications or cases of recurrence were reported., Conclusions: endoscopic submucosal dissection appears safe and effective for the resection of gastric inflammatory fibroid polyps that present as large subepithelial lesions, if performed by experienced endoscopists after adequate characterization by endoscopic ultrasound, with high rates of technical success and low recurrence rates.

Background: Gallbladder polyps are rare lesions protruding into the gallbladder lumen with variable clinical presentation. No standard treatment algorithm has been developed for pediatric gallbladders, and the malignant potential of the gallbladder is not clear in children. Therefore, a retrospective study was performed to evaluate the clinical features and treatment options of gallbladder polyps in children., Methods: Between 2014 and 2020, children diagnosed with gallbladder polyps were evaluated for age, gender, clinical features, results of follow-up with ultrasound findings, and treatment options retrospectively., Results: The records of 15 patients with a mean age of 13.2 years (2-20 years) were included. The male: female ratio was 7 : 8. Gallbladder polyps was detected incidentally in 73.3% (n = 11) of the patients. Four (20%) of the patients were symptomatic (26.7%) and complained about abdominal pain. Laboratory tests were normal except in 3 patients who showed slightly increased liver function tests. Two of the patients had 3 polyps on admission. The polyps were 2-10 mm in size. The size of the polyp increased in 5 patients (33.3%) and disappeared in 4 patients (26.6%) in follow-up ultrasound examinations. Five of the patients underwent cholecystectomy and 1 of them was scheduled for surgery. Five of the asymptomatic patients who have polyps less than 10 mm in size are still on follow-up. In patients with cholecystectomy, the histopathology of gallbladders revealed cholesterol polyps (n = 2) and hyperplastic polyps (n = 2). One of the patients with cholecystectomy showed no polyps in histopathological evaluation., Conclusion: Despite the lack of a standardized algorithm, our data suggested that multiple polyps, polyps with increased in size or greater than 10 mm, and the presence of symptoms might require cholecystectomy in children. Asymptomatic patients with small-sized polyps can be identified using ultrasound, and the polyps may disappear during the subsequent follow-up.

Objective: Ultrasonography (US) is the most commonly used radiological method in the diagnosis of gallbladder polyps (GBPs). Patients diagnosed with GBPs on US are operated on with risk factors that do not have a high level of evidence. Our aim in this study is to determine the sensitivity of US in diagnosis GBPs, to define risk factors for neoplastic (NP) polyps, and to develop the risk scoring system., Materials and Methods: Between July 2011 and July 2021, 173 patients who were found to have GBPs in the pathology specimens after cholecystectomy were included in the study. Patients were divided into two groups: nonneoplastic and NP groups., Results: GBPs in patients who underwent abdominal US for any reason was 4.5%. The sensitivity of US in the diagnosis of GBPs was 56.6%. Comparison between groups, age ≥50, presence of symptoms, polyp size >12.5mm, single polyp, concomitant gallstones, and gallbladder wall thickness ≥4mm were statistically in the NP group. A risk scoring system was developed using these values. If the risk score was <4, 0.6% of GBPs was NP polyps. If the risk score was ≥4, 63.2% of GBPs were NP polyps., Conclusion: Our risk scoring system can prevent unnecessary choelcystectomy. Because the incidence of NP polyps in low-risk patients (risk score <4) is extremely rare., (© 2022. The Society for Surgery of the Alimentary Tract.)

Objective: To identify the prevalence of and risk factors for chronic endometritis (CE) in patients with intrauterine disorders and the therapeutic efficacy of hysteroscopic surgery in the treatment of CE without antibiotic therapy., Design: Prospective cohort study., Setting: Hospital specializing in reproductive medicine., Patient(s): The study population consisted of 350 women with infertility, of whom 337 were recruited, who underwent hysteroscopic surgery between November 2018 and June 2021. Eighty-nine consecutive patients without intrauterine disorders were also recruited as controls., Intervention(s): Endometrial samples were collected during the surgery for CD138 immunostaining for the diagnosis of CE. In women diagnosed with CE, endometrial biopsy was performed without antibiotic use in the subsequent menstrual cycle., Main Outcome Measure(s): Prevalence of and risk factors for CE in intrauterine disorders and therapeutic effects of hysteroscopic surgery on CE., Result(s): The prevalence of CE with ≥5 CD138-positive cells in women with no intrauterine disorder and with endometrial polyps, myomas, intrauterine adhesions (IUAs), and septate uterus was 15.7%, 85.7%, 69.0%, 78.9%, and 46.2%, respectively. A multivariate analysis revealed that CE was diagnosed significantly more often in the endometrial polyp (odds ratio, 27.69; 95% confidence interval, 15.01-51.08) and IUA groups (odds ratio, 8.85; 95% confidence interval, 3.26-24.05). The rate of recovery from CE with surgery in women with endometrial polyps, myomas, IUA, and septate uterus was 89.7%, 100%, 92.8%, and 83.3%, respectively., Conclusion(s): Endometrial polyp and IUA were risk factors for CE. Most CE cases with intrauterine disorders were cured with hysteroscopic surgery without antibiotic therapy, regardless of the type of intrauterine abnormalities., (Copyright © 2022 American Society for Reproductive Medicine.

Long-term voice abuse or sudden vocal fold microvascular disruption may lead to injury and subsequent repair/remodeling in the vocal fold mucosa. Periostin is known to be involved in airway remodeling and also in various otolaryngological diseases. The aim of this article was to investigate the expression and the role of periostin in the formation of vocal fold polyps. The expression patterns of periostin in 59 surgical specimens of vocal fold polyps from 54 patients were investigated immunohistochemically. Normal vocal fold mucosa specimens from 5 patients who had undergone total laryngectomy were used as the control group. Retrospective study with planned data collection was conducted at Tohoku Medical and Pharmaceutical University. Expression of periostin was detected in 43 (72.9%) samples and four patterns of periostin expression were observed in vocal fold polyps: negative type, superficial type, infiltrative type, and diffuse type. An association was observed between periostin expression patterns and the histological subtypes of vocal fold polyps. The infiltrative pattern of periostin expression was significantly dominant in vascular-hyaline types. Expression of transforming growth factor-β (TGF-β) was also detected in the vocal fold polyps. Our results confirmed that periostin might be involved in certain pathological changes in vocal fold polyps, such as extracellular matrix accumulation, local fibrosis, and formation and development of vocal fold polyps.

Inflammatory fibroid polyp (IFP) is a rare, usually solitary and intraluminal polypoid benign tumour that can affect any part of the gastrointestinal (GI) tract. Its aetiology is unknown and clinical presentation depends on the site of involvement. We present the case of a 12-month-old girl with IFP and review all reported cases of IFP in children and adolescents <18 years. A 12-month-old girl presented with rectal bleeding. The patient underwent colonoscopy which revealed an anus polyp. Surgical resection was performed and histopathological examination of the specimen showed features of IFP. A literature review of 20 cases (including ours) between 1966 and January 2022 is also presented. To our knowledge, this is the youngest reported patient with IFP and the first in the anal area., (© 2022 Paediatrics and Child Health Division (The Royal Australasian College of Physicians).)

Objective: To evaluate the possibility of referring women with uterine polyps larger than 1.5 cm directly to surgical hysteroscopy., Methods: This retrospective cohort study included all women referred to a university-affiliated tertiary medical center for hysteroscopy, with the diagnosis of endometrial polyp, from 01/2013 to 05/2016. Women were referred for surgical hysteroscopy based on TVUS findings. PPV of TVUS for detecting intrauterine polyps was evaluated relating to pathology as gold standard, with sub-group analysis relating to polyp size and other parameters., Results: We selected 1.5 cm as a cutoff size for subgroup analysis of endometrial polyps. PPV of TVUS for the entire cohort of 295 cases eligible for analysis, was 79.3%. TVUS describing polyps ≥1.5 cm had PPV of 92.1%, higher than the PPV for smaller polyps. Among post-menopausal women in this group, PPV was as high as 96.2%. Use of doppler or saline was found to improve PPV in the entire cohort. Indication for performing TVUS did not affect the PPV., Conclusion: TVUS describing polyps ≥1.5 cm may suffice for direct referral of women to surgical hysteroscopy. A personalized approach based on the initial diagnosis may avoid unnecessary invasive procedures for patients., (© 2021 International Federation of Gynecology and Obstetrics.)

Background and Aim: Gallbladder polyps (GBPs) are relatively common. Many studies have attempted to distinguish between benign and neoplastic GBPs to identify early-stage gallbladder carcinoma. We have established an accurate neoplastic predictive model and evaluated the effectiveness of radiomics in predicting malignancy in patients with GBPs., Methods: A total of 503 patients confirmed through postoperative pathology were included in this retrospective study. Clinical information and ultrasonographic findings were retrospectively analyzed. The model was constructed from independent risk factors using Spearman correlation and logistic regression analysis of a training cohort of 250 GBP patients, and its efficacy was verified using an internal validation group of 253 consecutive patients through the receiver operating characteristic curve (ROC). The area of GBPs was delimited manually, and the texture features of ultrasound images were analyzed using correlation and ROC analysis., Results: Independent predictors, including age, gallstones, carcinoembryonic antigen, polyp size, and sessile shape, were incorporated into the nomogram model for the neoplastic potential of GBPs. Compared with other proposed prediction methods, the established nomogram model showed good discrimination ability in the training group (area under the curve [AUC]: 0.865) and validation group (AUC: 0.845). Regarding ultrasonic radiomics, the minimum caliper diameter was identified as the only independent predictor (AUC: 0.841)., Conclusions: Our preoperative nomogram model can successfully evaluate the neoplastic potential of GBPs using simple clinical data, and our study verified the use of radiomics in GBP identification, which may be valuable for avoiding unnecessary surgery in patients., (© 2022 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.)

Background: Fibrovascular polyps (FVPs) with hypopharyngeal pedicles (hFVPs) are the rare intraluminal benign tumours of the upper aerodigestive tract, and their accurate diagnosis and optimal management are challenging. Purpose: The present retrospective study attempted to explore the optimal diagnosis and treatment of hFVPs. Research Design: The clinical records of 2 patients with giant, irregularly shaped hFVPs, who underwent several failed surgical procedures after inaccurate diagnosis, were reviewed. Finally, the patients were correctly diagnosed and successfully treated at Capital Medical University Beijing Friendship Hospital in different years, 2018 and 2020. Results: Case 1 was of a 43-year-old woman with 2 months of progressive dysphagia. Gastroenterologists overlooked the origin of her FVP, and decided to sever its narrowest point in the oesophagus through endoscopy. However, upon unsuccessful removal of the mass, a gastrotomy procedure was performed to extract the mass 7 days later. Symptoms recurred 3 months after the treatment, and a fibreoptic laryngoscopy confirmed hFVP in the patient at our department. A transcervical approach was used to sever the hypopharyngeal pedicle, achieve haemostasis and remove the oesophageal tumour. No recurrence was detected during the 2-year follow-up period after the treatment. Case 2 was of a 32-year-old man with dysphagia who had previously undergone transthoracic and transcervical oesophagotomy procedures within a gap of 3 months for the removal of FVP causing dysphagia. The hypopharyngeal pedicle was not diagnosed in the patient. The symptoms of dysphagia recurred 4 years after the treatment, and a fibreoptic laryngoscope confirmed hFVP at our department. The tumour was removed successfully through the transcervical approach. No recurrence was detected during the 6-months follow-up after surgery. Conclusion: In conclusion, the transcervical approach is suitable for achieving haemostasis and removing giant, irregularly shaped hFVPs.

Background: The risk of neoplasia in gallbladder polyps seems to be low, but the evidence from populations at high-risk of gallbladder cancer is limited. We aimed to estimate the risk and to identify the factors associated with neoplastic polyps in a high-risk Hispanic population., Methods: A retrospective cohort was recruited between January 2010 and December 2019 at a Chilean university center. Multivariate survival analyses were conducted. Fine-Gray models were fitted to account for competing risks. Covariate adjustment was conducted using propensity scores. The main outcome was the development of gallbladder adenomas or adenocarcinoma., Results: Overall, 748 patients were included, 59.6% underwent cholecystectomy. The median follow-up of patients not subjected to cholecystectomy was 54.7 months (12-128.6 months). Seventeen patients (2.27%) developed the outcome. After adjustment by age, sex, intralesional blood flow, lithiasis and gallbladder wall thickening, only polyp size (≥10 mm, adjusted-HR: 15.01, 95%CI: 5.4-48.2) and number of polyps (≥3 polyps, adjusted-HR: 0.11, 95%CI: 0.01-0.55) were associated with neoplasia., Conclusion: In a Hispanic population at high-risk for gallbladder cancer, gallbladder polyps seem to have a low risk of neoplasia. Polyp size was the main risk factor, while having multiple polyps was associated with an underlying benign condition., Competing Interests: Conflict of interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2021.

Objective: To evaluate the clinical importance of endometrial polyp size measured using saline infusion sonohysterography (SIS) before performing a hysteroscopic resection in predicting premalignant/malignant lesions., Methods: A retrospective observational study analysis was conducted of 365 patients, who underwent SIS, in a reference hospital. The longest plane of the polyp size was taken as base. Polyps were classified as benign, premalignant, or malignant., Results: The rates of premalignant and malignant lesions were 7.4% and 0.9%, respectively. The mean polyp size was 17.7 ± 0.5 mm in benign patients and 23.7 ± 1.8 mm in premalignant/malignant individuals (P < 0.001). In the group of polyps that were 0-10, 10-20, 20-30, and >30 mm, premalignancy/malignancy rates were 0.0%, 4.8%, 13.3%, and 18.8%, respectively. The cut-off value for polyp size to be able to predict lesions was calculated as 22.5 mm (sensitivity: 63%, specificity: 80%) on receiver operating characteristics curve analysis (P = 0.001, area under the curve 0.732). The power of the study was calculated as 90.86%., Conclusion: During the female reproductive years, endometrial polyps smaller than 10 mm, as measured in SIS, can be followed. However, when the polyp size is 22.5 mm or more, especially in postmenopausal women, treatment should be planned., (© 2021 International Federation of Gynecology and Obstetrics.)

A 55-year-old woman was seen at an oral and maxillofacial surgery department because of a large oral swelling and complaints about difficulty eating, nasal speech and fatigue. She had full dentures in her upper jaw. Intraorally, a pain-free, pedunculated, combined solid-elastic and bone-hard tumour was found in the left maxillary tubercle region. A large, fibroepithelial polyp was diagnosed based on clinical and histopathological findings. Six weeks post-operatively, the complaints had disappeared. Chronic irritation of the oral mucosa can result in an oral fibroepithelial polyp that can be distinguished from peripheral ossifying fibroma or giant cell fibroma after histopathological examination. Such a polyp can grow to a large size if the source of irritation is not removed.

Background and Aims: Cholecystectomy is performed for most gallbladder polyps (GPs). However, cholecystectomy results concerning complications in some patients. For benign GPs, adoption of gallbladder-preserving surgery is worth to recommend. We describe our experiences performing gallbladder-preserving polypectomy for GPs by embryonic-natural orifice transumbilical endoscopic surgery (E-NOTES) with a gastric endoscopy., Methods: This is a retrospective study of patients with GPs who underwent gallbladder-preserving polypectomy by E-NOTES with a gastric endoscopy from April 2018 to September 2019 in our hospital. The operative time, intraoperative hemorrhage, intraoperative and postoperative complications, gallbladder emptying function were obtained and analyzed., Results: The procedure was performed successfully in all 12 patients with 5 cases of single polyp and 7 cases of multiple polyps. The range of GPs size was 2 mm to 15 mm. The mean operation time was (95.33 ± 23.08) minutes (55-135 min). There were no adverse events including heavy bleeding, mortality and conversion to open surgery during operation. All patients were discharged in 4-5 days after surgery without postoperative complications such as delayed bleeding, fever, peritonitis, intra-abdominal abscess and abdominal wall incisional hernia. All patients were followed up at 1, 3, 6, and 12 months postoperation who had almost no visible incision on the umbilical region, no recurrent GPs. The gallbladder emptying function decreased one month after surgery, and gradually improved 3, 6 and 12 months after surgery., Conclusion: E-NOTES gallbladder-preserving polypectomy is a safe and effective option for patients with GPs and is close to scar-free surgery which can be performed in routine clinical practice., (© 2022.

We evaluated resectoscopic surgery for definitive diagnosis and long-term therapy in 16 symptomatic tamoxifen-treated women with breast cancer who presented with abnormal uterine bleeding and/or intrauterine anomalies. Seven pre-menopausal women had benign pre- and post-operative endometrial biopsy, and 4 had benign polyps. At a median of 7 years of follow-up (range 2-8 y), all remained amenorrheic. Of 9 post-menopausal women, pre-operative biopsy was inadequate in 4, benign endometrium was found in 4, and non-atypical endometrial hyperplasia was found in 1. Post-operatively, all had benign pathology, 8 having polyp and 1 leiomyoma. At a median follow-up of 7 years (range 2-13 y), all were amenorrheic, with no recurrence of breast cancer or uterine pathology., (Copyright © 2021 The Society of Obstetricians and Gynaecologists of Canada/La Société des obstétriciens et gynécologues du Canada.
