Background: Identifying the risks related to the complications of electrical cardioversion (ECV) can alert the determinaton of rhythm control in patients with atrial fibrillation (AF). Methods: We retrospectively reviewed 1,058 patients who underwent ECV for persistent or long-standing persistent AF/atrial flutter (AFL) from multiple centers. Patients were classified into the no-complication (1,023 patients) and complication (35 patients) groups based on the following major complications: stroke and/or systemic embolism (SSE), myocardial infarction, major bleeding, implantation of cardiac implantable electronic devices, ventricular tachycardia/fibrillation, and death at 1 year follow-up after ECV. Results: Compared with the no-complication group, the complication group exhibited a higher proportion of female patients (37% vs. 22%), as well as a higher proportion of patients with older age (67 ± 11 vs. 61 ± 10 years), diabetes mellitus (DM) (49% vs. 24%), heart failure (HF) (49% vs. 30%), SSE (23% vs. 9%), high CHA 2 DS 2 -VASc (CV) score (3.6 ± 1.8 vs.2.2 ± 1.4), low left ventricular ejection fraction (LVEF) (50 ± 16% vs. 58 ± 21%), and high left atrial volume index (LAVI) (51 ± 26 vs. 40 ± 20 mL/m 2 ). Class I and III antiarrhythmics were less prescribed in the complication group than in the no-complication group (57% vs.76%). Univariate analysis for complications revealed age (≥ 65 years), female sex, DM, HF, SSE, LVEF (< 50%), LAVI (≥ 40 mL/m 2 ), CV score (≥ 3), bradycardia on Holter (< 60/min), and no antiarrhythmics as risk factors. Among these, multivariate analysis revealed clinical significance of female sex and SSE. Conclusion Female sex and a history of SSE were the most important risk factors of complications in patients with persistent or long-standing persistent AF/AFL who underwent ECV.

Background: Volar plate fixation for distal radial fractures is the most common cause of closed rupture of the flexor pollicis longus tendon (FPL). For treating a closed FPL rupture, transferring the fourth flexor digitorum superficialis or a tendon graft from the palmaris longus (PL) can be performed. This study reports the results of tendon grafting using the PL in closed FPL rupture and discusses the provision of optimal tendon tension. Methods: This retrospective study included 11 out of 20 patients who underwent PL tendon graft for closed FPL rupture between 2013 and 2022, with a follow-up period of more than 12 months. There were 4 men and 7 women, with an average age of 62 years. The average period from the date of rupture to surgery was 39 days. Ruptures occurred due to volar plate fixation in 7 cases, without a specific cause in 2 cases, and after a steroid injection for trigger thumb in 2 cases. The rupture site was in zone 2 in 4 cases and zone 5 in 7 cases. The mean follow-up period was 59 months. Optimal tension for the grafted tendon was determined by comparing the intraoperative angles of the interphalangeal (IP) and metacarpophalangeal (MCP) joints with the angles of the same joints at the final follow-up. Results: At the final follow-up, the mean IP joint motion was 61.0°, which was 81.5% of the contralateral side. The average range of motion of the MCP joint was 43.6°, which was 80.0% of the contralateral side. The pinch power was 90.8% of the contralateral side. Cases with > 70° IP joint motion were those in which the IP joint angle was > 45° during surgery. Moreover, the greater the flexion of the IP and MCP joints intraoperatively, the better the range of motion of the IP joints. Conclusions Tendon grafting using the PL is recommended as an effective surgical method to achieve 81.5% of contralateral IP joint motion in cases of closed FPL tendon rupture. Over-tensioning of the tendon graft with IP Joint flexion more than 45° during surgery is recommended.

Purpose: Commonly used surgical approaches for internal plate fixation of transcondylar distal humeral fractures may require ulnar nerve release or anterior transposition, and extensive surgical dissection can cause triceps weakness. This study reports the surgical technique and clinical outcomes of a medial and lateral approach for dual-plate fixation of transcondylar distal humeral fractures without ulnar nerve release or extensive surgical dissection. Methods: Sixteen patients (mean age, 81.25 years; range, 70–95 years) who underwent plate fixation using a medial and lateral approach for distal humeral transcondylar fractures were retrospectively reviewed. An anatomical distal humerus parallel or orthogonal locking plate was used for internal fixation. Ulnar nerve release was not performed in any patients. Surgical outcomes were evaluated 1 year postoperatively based on the level of pain, elbow range of motion, the Mayo elbow performance score, and postoperative complications. Results: The mean visual analog scale score was 0.47. The mean range of motion of the elbow joint was 13.8° for extension and 131.8° for flexion. The Mayo Elbow Performance Score was excellent in nine patients and good in seven. Bone union was achieved in all patients. There were no complications such as ulnar neuropathy, heterotopic ossification, or infection. Conclusion In transcondylar distal humeral fracture in older adults, a medial and lateral approach with dual anatomical locking plate fixation is recommended as a surgical technique that has the advantage of enabling rigid fixation without necessitating ulnar nerve release and extensive surgical dissection. Nonetheless, further research should be conducted.

Since its development, the use of endoscopic ultrasonography (EUS) in the pancreas and the biliary tract has become increasingly important. The accuracy of EUS varies depending on the experience of the endoscopist. Hence, quality control measures using appropriate indicators are required to reduce these variations. American Society for Gastrointestinal Endoscopy and European Society of Gastrointestinal Endoscopy have announced the EUS quality indicators. Here, we reviewed the quality indicators of the EUS procedure in the current published guidelines.

Purpose: Outcome analysis of urachal cancer (UraC) is limited due to the scarcity of cases and different staging methods compared to urothelial bladder cancer (UroBC). We attempted to assess survival outcomes of UraC and compare to UroBC after stage-matched analyses. Materials and Methods: Total 203 UraC patients from a multicenter database and 373 UroBC patients in single institution from 2000 to 2018 were enrolled (median follow-up, 32 months). Sheldon stage conversion to corresponding TNM staging for UraC was conducted for head-to-head comparison to UroBC. Perioperative clinical variables and pathological results were recorded. Stage-matched analyses for survival by stage were conducted. Results: UraC patients were younger (mean age, 54 vs. 67 years; p < 0.001), with 163 patients (80.3%) receiving partial cystectomy and 23 patients (11.3%) radical cystectomy. UraC was more likely to harbor ≥ pT3a tumors (78.8% vs. 41.8%). While 5-year recurrence-free survival, cancer-specific survival (CSS) and overall survival were comparable between two groups (63.4%, 67%, and 62.1% in UraC and 61.5%, 75.9%, and 67.8% in UroBC, respectively), generally favorable prognosis for UraC in lower stages (pT1-2) but unfavorable outcomes in higher stages (pT4) compared to UroBC was observed, although only 5-year CSS in ≥ pT4 showed statistical significance (p=0.028). Body mass index (hazard ratio [HR], 0.929), diabetes mellitus (HR, 1.921), pathologic T category (HR, 3.846), and lymphovascular invasion (HR, 1.993) were predictors of CSS for all patients. Conclusion Despite differing histology, UraC has comparable prognosis to UroBC with relatively favorable outcome in low stages but worse prognosis in higher stages. The presented system may be useful for future grading and risk stratification of UraC.
