ABSTRACT

BACKGROUND AND AIMS: Endoscopic polypectomy can prevent colorectal cancer. Adequate surgical field visualization is crucial to complete resection. To prevent visual field loss caused by intestinal peristalsis, we investigated the efficacy and safety of topical lidocaine spraying during the endoscopic sigmoid polypectomy (ESP).

METHODS: Retrospective analysis was performed on 100 ESP patients admitted from July 2021 to October 2021, among which 50 patients received lidocaine (case group) and other 50 patients received normal saline (control group). Lidocaine or saline was sprayed on the colonic mucosa within 5 cm above and below the polyps before polypectomy. The en-bloc resection rate (EBRR) and complete resection rate (CRR) were primarily evaluated. Secondary outcomes included EBRR for polyps located in the 5-11 o’clock position, sigmoid colon peristalsis frequency, degree of exposure to the surgical field, operative times, and adverse events.

RESULTS: There were no significant differences in the basic demographic characteristics between the two groups. EBRR and CRR in the case group were 72.9% and 95.8%, and in the control group were 53.3% and 91.1%, respectively. The EBRR of sigmoid polyps located at the 5-11 o’clock positions was significantly higher in the case group (82.8%) than in the control group (56.7%) (P = 0.03). Sigmoid colonic peristalsis was significantly inhibited after lidocaine spraying (P < 0.01). There was no statistical difference in the operative times and adverse event rates between the two groups.

CONCLUSION: Topical spraying lidocaine around polyps can safely and effectively reduce intestinal peristalsis, thus improving the EBRR of sigmoid polypectomy.

ABSTRACT

BACKGROUND: This study aimed to investigate the efficacy and safety of transjugular intrahepatic portosystemic shunt (TIPS) in the treatment of patients with pyrrolidine alkaloids-induced hepatic sinusoidal obstruction syndrome (PA-HSOS).

METHODS: Patients diagnosed with PA-HSOS and treated in Ningbo No.2 Hospital between November 2017 and October 2022 were enlisted in this retrospective cohort study.

RESULTS: This cohort comprised a total of 22 patients with PA-HSOS, of which 12 patients received TIPS treatment and 10 patients experienced conservative treatment. The median follow-up duration was 10.5 months. Baseline characteristics existed with no significant difference between the two groups. No operation failures or any TIPS-associated intraoperative complications were observed after TIPS. In the TIPS group, the portal venous pressure was substantially decreased from 25.3 ± 6.3 mmHg to 14.4 ± 3.5 mmHg after TIPS (P = 0.002). Compared with preoperative, the ascites after TIPS were significantly subsided (P = 0.001) and there existed a considerable decrease in Child-Pugh score. At the end of follow-up, 5 patients died, involving 1 in the TIPS group and 4 in the conservative treatment group. The median survival time was 13 (3-28) months in the TIPS group and 6.5 (1-49) months in the conservative treatment group, respectively. The survival analysis demonstrated that the total survival time of TIPS group was longer than that of the conservative treatment group, no statistical significance was observed (P = 0.08).

CONCLUSION: TIPS may be a secure and effective therapeutic strategy for PA-HSOS patients who do not respond to conservative treatment.

ABSTRACT

BACKGROUND AND AIMS: In endoscopic ultrasound (EUS)-fine-needle biopsy (FNB) of solid pancreatic mass lesions, the number of times the needle moves back and forth within the lesion might affect the collection of the sample and the subsequent diagnostic accuracy. Thus, this study was designed to compare the diagnostic adequacy between different numbers of back-and-forth movements in EUS-FNB.

METHODS: Fifty-five patients with solid pancreatic masses underwent EUS-FNB sampling with the needle (22-gauge) moved 20 times (MTT) and 40 times (MFT) randomly and sequentially for a total of four alternating passes. We compared the acquisition rate of appropriate and adequate specimens for histologic assessment and diagnostic accuracy.

RESULTS: Finally, 55 patients (35 men and 20 women) were included in the study. We found that 56.4% (31/55) and 60% (33/55) of the specimens obtained using MTT and MFT, respectively, could be adequately diagnosed histologically (P = 0.815, McNemar test). The diagnostic accuracy of MTT and MFT was 72.7% (40/55) and 80% (44/55), respectively (P = 0.289, McNemar test). The overall diagnostic accuracy was 89.1%.

CONCLUSION: There was no significant statistical difference between the histopathological diagnostic samples obtained in MTT and those obtained in MFT. Therefore, a large number of back-and-forth movements of the needle should be avoided during EUS-FNB, which can help reduce the operation time and may reduce the risk of intraoperative and postoperative complications (Clinical trial registration number: ChiCTR2000031106).

ABSTRACT

OBJECTIVE: Harmfulness of foreign body ingestion and food bolus impaction (FBIs) varies according to geographical area, population, habits, and diet. Therefore, studies may not draw generalizable conclusions. Furthermore, data regarding FBIs management in Europe are limited and outdated. This study aimed to analyze the endoscopic management and outcomes of FBIs in an Italian tertiary care hospital to identify risk factors for endoscopic failure.

METHODS: We retrospectively reviewed patients who underwent upper gastrointestinal endoscopy for FBIs between 2007 and 2017. Baseline, clinical, FBIs, and endoscopic characteristics and outcomes were collected and reported using descriptive statistics and logistic regression analyses.

RESULTS: Of the 381 endoscopies for FBIs, 288 (75.5%) were emergent endoscopy and 135 (35,4%) included underlying upper gastrointestinal conditions. The study population included 44 pediatric patients (11.5%), 54 prisoners (15.8%), and 283 adults (74.2%). The most common type and location of FBIs were food boluses (52.9%) and upper esophagus (36.5%), respectively. While eight patients (2.1%) developed major adverse events requiring hospital admission, the remainder (97.9%) were discharged after observation. No mortality occurred. Endoscopic success was achieved in 263 of 286 (91.9%) verified FBIs endoscopies. Endoscopic failure (8.04%) was associated with age, bone, disk battery, intentional ingestion, razor blade, prisoners, and stomach in the univariate analysis. Multivariate logistic regression revealed that intentional ingestion was associated with endoscopic failure (odds ratio: 7.31; 95% confidence interval = 2.06-25.99; P = 0.002).

CONCLUSION: Endoscopy for FBIs is safe and successful, with low hospital admission rate in children, prisoners, and adults. Intentional ingestion is a risk factor of endoscopic failure.

ABSTRACT

BACKGROUND: The effectiveness of arthroscopic treatment for knee osteoarthritis (OA) has been controversial. This study compares the clinical outcomes of the arthroscopic cartilage regeneration facilitating procedure (ACRFP) and conservative treatment.

METHODS: During the year of 2016, 524 patients (882 knees) who were older than 40 years of age and diagnosed with different stages of knee OA were scheduled for ACRFP under the protocol of knee health promotion option (KHPO) for knee OA. Of those, 259 patients (413 knees) eventually received ACRFP (the ACRFP group), and 265 patients (469 knees) didn’t receive ACRFP but received conservative treatment (the non-ACRFP group). A telephone questionnaire was used to evaluate the subjective satisfaction and the incidence of receiving arthroplasty for these patients.

RESULTS: After the mean follow-up period of 61.6 months (SD 4.5), there were 220 patients (374 knees, 90.6%) in the ACRFP group and 246 patients (431 knees, 90.0%) in the non-ACRFP group completed the outcome study. The satisfactory rate was statistically higher for the ACRFP group (90.64%) than for the non-ACRFP group (70.3%) and the difference in subjective satisfaction was more obvious in patients with more advanced knee OA. As for the incidence of patients having subsequently received arthroplasty, it was higher (13.46%) in the non-ACRFP group than in the ACRFP group (4.28%).

CONCLUSION: Compared with conservative treatment, ACRFP could satisfy more patients with knee OA and modify their natural course by decreasing the incidence of subsequent arthroplasty.

ABSTRACT

OBJECTIVE: To investigate the association between body composition and prognosis in patients with advanced hepatocellular carcinoma treated with atezolizumab plus bevacizumab.

METHODS: This cohort study analysed 119 patients who received atezolizumab plus bevacizumab for unresectable hepatocellular carcinoma. We investigated the association between body composition and progression-free survival and overall survival. Body composition was quantified by the visceral fat index, subcutaneous fat index, and skeletal muscle index. A high or low index score was defined as that above or below the median of these indices.

RESULTS: Poor prognosis was observed in the low visceral fat index and low subcutaneous fat index groups. The mean progression-free survival in the low visceral fat index and low subcutaneous fat index groups vs. the other groups were 194 and 270 days, respectively [95% confidence interval (CI), 153-236 and 230-311 days, respectively; P = 0.015], while the mean overall survival was 349 vs. 422 days, respectively (95% CI, 302-396 and 387-458 days, respectively; P = 0.027). In the multivariate analysis, both a low subcutaneous fat index and low visceral fat index were statistically associated with lower progression-free and overall survival rates [hazard ratio (HR) 1.721; 95% CI, 1.101-2.688; P = 0.017; and HR 2.214; 95% CI, 1.207-4.184; P = 0.011, respectively].

CONCLUSION: Low visceral fat index and subcutaneous fat index scores were independent predictors of poor prognosis in patients with unresectable hepatocellular carcinoma treated with atezolizumab plus bevacizumab.

ABSTRACT

OBJECTIVE: To determine the effects of propofol (P) alone and in combination with ketamine (KP) at ratios of 1:1, 1:2, and 1:3 on intraocular pressure (IOP) in unpremedicated dogs.

ANIMALS STUDIED: A total of 28 cross-bred healthy dogs.

PROCEDURES: Dogs were randomly assigned to one of four groups (n = 7 per group) to receive intravenous P or KP at 1:1, 1:2, and 1:3 ratios, respectively. The infusion was administered at 0.6 mg/kg/min for 60 min. IOP, cardiorespiratory variables, rectal temperature (RT), and pedal reflex were recorded every 5 min for 60 min, starting from baseline (BL).

RESULTS: There was a statistically significant increase in IOP in all groups: P (p = .011), KP 1:1 (p = .003), KP 1:2 (p = .023), and KP 1:3 (p = .008). The IOP increase was less pronounced in the KP 1:2 group and was only significant (p = .023) at T45 compared with BL. A significant correlation was observed between IOP and SpO₂ in P (r = -.215, p = .02), KP 1:2 (r = -.579, p < .01), and KP 1:3 (r = -.402, p < .01) groups. IOP significantly increased due to decreased SpO₂ below 86.5% (p < .05).

CONCLUSIONS: Propofol alone and in combination with ketamine may increase preexisting IOP in unpremedicated dogs. SpO₂ levels below 86.5% may trigger an increase in IOP. Administering KP in a 1:2 ratio at an infusion rate of 0.6 mg/kg/min does not significantly alter IOP for under 45 min in unpremedicated dogs with sufficient oxygenation.

ABSTRACT

BACKGROUND: Anterior cruciate ligament (ACL) injuries are among the most common injuries in adolescent athletes and result in significant financial and physical morbidity. Evidence-based programs designed to prevent ACL injury are effective. However, their adoption remains low. We sought to evaluate the awareness, evidence-based implementation, and barriers to implementation of ACL injury prevention programs (ACL-IPP) among youth athletic coaches.

HYPOTHESIS: Higher education level of the coach, higher level of training, number of teams coached, and coaching female teams would be associated with ACL-IPP implementation.

STUDY DESIGN: Cross-sectional survey.

LEVEL OF EVIDENCE: Level 4.

METHODS: We conducted an email survey sent to all 63 school districts within Section VI of the New York State Public High School Athletic Association. We employed descriptive statistics and tests of correlation to identify factors associated with ACL-IPP implementation.

RESULTS: A total of 73% of coaches said they were aware of ACL-IPP, and only 12% of coaches implemented ACL-IPP according to best evidence. Coaches of higher competitive levels were more likely to adopt ACL-IPP (P = 0.01), more likely to use them multiple times per week (P = 0.03), and for ≥1 seasons (P = 0.02). Coaches of multiple teams were more likely to adopt ACL-IPP (P = 0.01). There were no differences in evidence-based implementation of ACL-IPP with gender coached or level of education of the coach.

CONCLUSION: Overall awareness, adoption, and evidence-based implementation of ACL-IPP remain low. These results suggest that coaches at higher levels of play and multiple teams tend to use ACL-IPP more often. Gender coached and level of education do not appear to be associated with awareness or implementation.

CLINICAL RELEVANCE: Evidence-based ACL-IPP implementation remains low. Targeting coaches of younger athletes and fewer teams with local outreach programs and ACL-IPP may increase the implementation of ACL-IPP.

ABSTRACT

BACKGROUND: Primary cardiac sarcomas are rare and their clinicopathologic features are heterogeneous. Among them, particularly intimal sarcoma is a diagnostic challenge due to nonspecific histologic features. Recently, MDM2 amplification reported to be a characteristic genetic event in the intimal sarcoma. In this study, we aimed to identify the types and incidence of primary cardiac sarcomas that occurred over 25 years in tertiary medical institutions, and to find clinicopatholgical significance through reclassification of diagnoses using additional immunohistochemistry (IHC).

METHODS: We reviewed the primary cardiac sarcoma cases between January 1993 and June 2018 at Asan Medical Center, South Korea, with their clinicopathologic findings, and reclassified the subtypes, especially using IHC for MDM2 and then, analyzed the significance of prognosis.

RESULTS: Forty-eight (6.8%) cases of a primary cardiac sarcoma were retrieved. The tumors most frequently involved the right atrium (n = 25, 52.1%), and the most frequent tumor subtype was angiosarcoma (n = 23, 47.9%). Seven cases (53.8%) were newly reclassified as an intimal sarcoma by IHC for MDM2. Twenty-nine (60.4%) patients died of disease (mean, 19.8 months). Four patients underwent a heart transplantation and had a median survival of 26.8 months. This transplantation group tended to show good clinical outcomes in the earlier stages, but this was not statistically significant (p = 0.318). MDM2 positive intimal sarcoma showed the better overall survival (p = 0.003) than undifferentiated pleomorphic sarcoma. Adjuvant treatment is beneficial for patient survival (p < 0.001), particularly in angiosarcoma (p < 0.001), but not in intimal sarcoma (p = 0.154).

CONCLUSION: Our study supports the use of adjuvant treatment in primary cardiac sarcoma, as it was associated with a significantly better overall survival rate. Further consideration of tumor histology may be important in determining the optimal use of adjuvant treatment for different types of sarcomas. Therefore, accurate diagnosis by MDM2 test is important condsidering patient’s prognosis and treatment.
