Comparison of laparoscopic common bile duct exploration plus cholecystectomy and endoscopic retrograde cholangiopancreatography followed by laparoscopic cholecystectomy for elderly patients with common bile duct stones and gallbladder stones.

BACKGROUND: Common bile duct (CBD) stones commonly occur in cholecystectomy cases. The management options include laparoscopic CBD exploration (LCBDE) or endoscopic retrograde cholangiopancreatography (ERCP) followed by laparoscopic cholecystectomy (LC). Although ERCP is fully developed, it has complications, and LCBDE is a proven alternative. This study aimed to evaluate the safety and efficacy of these treatments in elderly individuals aged ≥70 years. METHODS: A retrospective study between January 2015 and July 2022 included 160 elderly patients (aged ≥70 years) diagnosed with cholelithiasis and choledocholithiasis. The patients were divided into 1-stage (LCBDE [n = 80]) or 2-stage (ERCP followed by LC [n = 80]) treatment groups. Data collected encompassed comorbidities, symptoms, bile duct clearance, postoperative complications, and long-term outcomes for systematic analysis. RESULTS: This study analyzed 160 patients treated for CBD stones, comparing 1-stage and 2-stage groups. The 1-stage group had more female patients than the 2-stage group (57.5% vs 37.5%, respectively). The 1-stage group had a mean age of 80.55 ± 7.00 years, which was higher than the mean age in the 2-stage group. American Society of Anesthesiologists classification, Charlson Comorbidity Index, and laboratory findings were similar. Pancreatitis and cholangitis occurred after ERCP in the 2-stage group. Stone clearance rates (92.35% [1-stage group] vs 95.00% [2-stage group]) and biliary leakage incidence (7.5% [1-stage group] vs 3.0% [2-stage group]) were similar, as were postoperative complications and long-term recurrence rates (13.0% [1-stage group] vs 12.5% [2-stage group]). CONCLUSION: Our research indicates that both the combination of LCBDE and LC and the sequence of ERCP followed by LC are equally efficient and secure when treating CBD stones in elderly patients. Consequently, the 1-stage procedure may be considered the preferred treatment approach for this demographic.

Risk factors for postoperative vocal fold fibrosis following microlaryngeal surgery.

Objective: To analyze the risk factors for postoperative vocal fold fibrosis (PVF) in patients undergoing microlaryngeal surgery (MLS) for benign vocal fold lesions. Study Design: Retrospective study. Methods: We retrospectively included patients who had undergone MLS for vocal polyps, nodules, mucus retention cysts, fibrous mass, or Reinke's edema. Data on the patients' clinicodemographic characteristics and intraoperative findings were obtained by reviewing their clinical records. PVF was defined by the presence of an adynamic segment of membranous vocal folds or a marked reduction in mucosal wave amplitude on post-MLS (6 weeks) videolaryngostroboscopy. The risk factors for PVF were analyzed through univariate and multivariate logistic regressions. Results: This study included 89 patients, of whom 16 (18%) were given a diagnosis of PVF. A significantly increased incidence of PVF was noted in patients with fibrous mass (p < .01). The univariate analysis indicated that lesion attachment to the vocal ligament, prolonged surgical duration (>60 min), and symptom duration (>12 months) were significantly correlated with PVF (p < .05). The multivariate analysis confirmed that diagnosis of fibrous masses, lesion attachment to the vocal ligament and symptom duration are significant risk factors for PVF. Conclusion: PVF is more common in patients with fibrous masses. Lesions attachment to the vocal ligament and prolonged symptom duration appear to be other significant risk factors for PVF. Level of Evidence: 4.

Moderating Effects of Religious Tourism Activities on Environmental Risk, Leisure Satisfaction, Physical and Mental Health and Well-Being among the Elderly in the Context of COVID-19.

The purpose of this study is to explore whether religious tourism activities can create a safe leisure environment and improve the well-being of the elderly during the COVID-19 pandemic, with the participants in the Baishatun Mazu pilgrimage in Taiwan as the subjects of this study. A mixed research method was used. First, statistical software and the Pearson product-moment correlation coefficient were used to analyze the data. Then the respondents' opinions were collected. Finally, a multivariate analysis method was used to discuss the results of analysis. The findings showed that the elderly respondents thought that the epidemic prevention information and leisure space planning for the pilgrimage made them feel secure. The elderly believed the scenery, religious atmosphere, and commodities en route could reduce the perception of environmental risks to tourists, relieve pressure on the brain, and increase social opportunities. Therefore, the friendlier the leisure environment around the pilgrimage, the greater the leisure satisfaction among the elderly respondents. The happier the elderly felt, the less they considered the concentration of airborne contaminants, including viruses. The better their physical and mental health was, the less likely they were to want to ask for religious goods.

Incorporating sperm DNA fragmentation index with computer-assisted semen morphokinematic parameters as a better window to male fertility.

This study aimed to assess (1) the reproducibility of three sperm chromatin dispersion (SCD) assays for sperm DNA fragmentation, i.e., LensHooke R10® (R10), Halosperm G2® (G2), and BASO® (BA); (2) the correlation between computer-assisted semen analyzer (CASA) morphokinematic parameters and sperm DNA fragmentation index (DFI), and (3) the diagnostic value for male reproduction by combining semen morphokinematic parameters and DFI. Total 50 male participants were recruited, and all collected semen samples underwent semen analyses and SCD assays. Intra- and inter-observer variability of DFI data from different SCD measures was tested. In addition, the predictive ability of CASA parameters and DFI (with different cutoffs, i.e., 15% and 20%) for infertility was assessed using receiver operating characteristic curve analysis. We found that the G2 and R10 produced satisfactory variance coefficients (5.53%, 5.67%) compared to BA (14.8%). The DFI data from the R10 had lower intra-observer variability, in terms of higher intra-class coefficient (0.9615), than that of the G2 (0.8847) or BA (0.8824). Inter-observer variability of three SCD kits in scoring the DFI was comparable and satisfactory (concordance correlation coefficients ranging 0.9895-0.9630). The CASA parameters (i.e., total motility [r = -0.57], progression motility [r = -0.55], and rapidly progressive motility [r = -0.55]) were significantly correlated with DFI (P < 0.001). The predictive ability of the 15%-cutoff DFI data was better than that of the 20%-cutoff or continuous DFI data. The model comprising the CASA parameters, 15%-cutoff DFI, and 4%-cutoff normal morphology had the highest area under curve (0.8125) for infertility. For SCD assay, the R10 was the most reliable SCD assay to detect sperm DNA fragmentation. Combining the sperm DFI with CASA parameters might be a better diagnostic tool for male reproduction.

FOXM1-CD44 Signaling Is Critical for the Acquisition of Regorafenib Resistance in Human Liver Cancer Cells.

Regorafenib is a multikinase inhibitor that was approved by the US Food and Drug administration in 2017. Cancer stem cells (CSCs) are a small subset of cancer-initiating cells that are thought to contribute to therapeutic resistance. The forkhead box protein M1 (FOXM1) plays an important role in the regulation of the stemness of CSCs and mediates resistance to chemotherapy. However, the relationship between FOXM1 and regorafenib resistance in liver cancer cells remains unknown. We found that regorafenib-resistant HepG2 clones overexpressed FOXM1 and various markers of CSCs. Patients with hepatocellular carcinoma also exhibited an upregulation of FOXM1 and resistance to regorafenib, which were correlated with a poor survival rate. We identified a close relationship between FOXM1 expression and regorafenib resistance, which was correlated with the survival of patients with hepatocellular carcinoma. Thus, a strategy that antagonizes FOXM1-CD44 signaling would enhance the therapeutic efficacy of regorafenib in these patients.

Single-incision versus four-incision laparoscopic transfistulous bile duct exploration for Mirizzi syndrome type II.

BACKGROUND: We developed laparoscopic transfistulous bile duct exploration (LTBDE) for Mirizzi syndrome (MS) McSherry type II in September 2011. Then, single-incision LTBDE (SILTBDE) was adopted as a preferred technique since August 2013. This retrospective study aims to analyze the outcome of LTBDE in 7.7 years and to compare SILTBDE with four-incision LTBDE (4ILTBDE). METHODS: Seventeen consecutive patients underwent LTBDE for MS McSherry type II from September 2011 to May 2019. Transfistulous removal of the impacted stone(s), choledochoscopic bile duct exploration, and primary closure of the gallbladder remnant were performed without biliary drainage. RESULTS: The sex ratio is 12:5 (male: female) with an average age of 39.4 ± 10.3 (24-56) years. Ten patients (58.8%) had their diagnoses of MS established by preoperative imaging. According to the Csendes classification, three type II (17.6%), nine type III (52.9%), and five type IV (29.4%) were identified. The operative time was 264.8 ± 60.3 min (156-358 min). The stone clearance rate was 100%. The postoperative hospital stay was 4.7 ± 1.9 (2-10) days. No procedure was converted to an open operation. Two postoperative transient hyperamylasemia (11.8%) and one superficial wound infection (5.9%) occurred and all recovered well under conservative treatment (Clavien-Dindo grade I). During an average 2.2-year follow-up period, no biliary stricture or stone recurrence occurred. No significant difference exists between the SILTBDE and 4ILTBDE groups. Nevertheless, an insignificant trend of shorter postoperative hospital stay was observed in the former. A diagnosis of MS Csendes type IV implicates prolonged total and postoperative hospital stays (p < 0.01). CONCLUSIONS: LTBDE is safe and efficacious for MS McSherry type II. It provides a simple solution for various types of MS and avoids undesirable complications following bilioenteric anastomosis. SILTBDE is comparable to 4ILTBDE for selected patients. Patients with MS Csendes type IV need more time to recover after surgery.

Transoral Endoscopic-Assisted Retrieval of Extraluminal Parapharyngeal Foreign Body.

The ingested fish bone (FB) is a common presentation for otolaryngologists in Asia. For FBs which could be identified by examinations with or without nasopharyngoscopy, direct removal would be an appropriate management. However, an ingested FB could occasionally perforate pharyngeal mucosa and migrate extraluminally. Otolaryngologists should be extremely careful while evaluation and management of extraluminal FBs to prevent life-threatening condition. In this case report, we present a patient with a parapharyngeal extraluminal FB for 2 days which was detected by computed tomography scan of the neck. A transoral endoscopic-assisted retrieval of fish bone was performed after right tonsillectomy.

Galvanic vestibular-evoked myogenic potentials in evaluating damaged sites of vestibular neuritis.

Objectives: To test the possibility of pure otolithic organ deficits and validate the histopathological evidence of retrovestibular neural impairment in vestibular neuritis (VN), the authors adopted a topographic survey combining cervical vestibular-evoked myogenic potential (cVEMP) and ocular vestibular-evoked myogenic potential (oVEMP) using various stimulation modes and caloric tests. Methods: Forty patients with VN were enrolled in this study. All patients underwent pure tone audiometry, acoustic cVEMP, galvanic cVEMP, vibratory oVEMP, galvanic oVEMP, and caloric tests. Different combinations of vestibular tests were further compared and analyzed. Results: According to vestibular test results in affected VN ears, the proportion (10%) of pure saccular dysfunction was significantly less than that (52.5%) of saccular nerve deficit. The proportion (2.5%) of pure utricular dysfunction was significantly less than that (37.5%) of utricular nerve deficit. The percentage (82.5%) of VN involving the ampullar vestibulo-ocular reflex (VOR) pathway was significantly higher than that (40%) involving the utriculo-ocular reflex (UOR) pathway. The superior, inferior, and total VN percentages were 37.5%, 17.5%, and 45%, respectively. The proportion of inferior VN was significantly less than that of VN involving the superior vestibular nerve. Conclusion: There were significantly fewer cases of pure otolithic organ dysfunction than vestibular nerve involvement in VN patients. The damage to the ampullar VOR pathway was more significant than that to the UOR pathway, and both pathways might be independent of each other. In addition, the incidence of isolated inferior VN was significantly less than that of VN involving the superior vestibular nerve. Level of Evidence: Level 3.

The experience of use of percutaneous transhepatic biliary drainages for early biliary complications after liver transplantation.

This study aimed to describe our experience and discuss the results, controversies, and the use of percutaneous transhepatic biliary drainage (PTBD) in patients with biliary complications after liver transplantation (LT). Between November 2009 and August 2020, 76 consecutive patients who underwent 77 LTs (44 deceased donor LTs and 33 living donor LTs [LDLT]) were enrolled retrospectively. Endoscopic therapy as initial approach and PTBD as rescue therapy were used for patients with biliary complications. There were 31 patients (31/76, 40.8%) with biliary complications, and two of them died (2/31, 6.5%). Clinical success rate of endoscopic therapy alone was 71.0% (22/31). The remaining nine patients received salvage PTBD and their clinical results were observed according to whether their intrahepatic bile ducts (IHBDs) was dilated (group A, n = 5) or not (group B, n = 4). In group A, the technical and long-term clinical success rates of PTBD were 100% and 20%, respectively. These five patients received PTBD ranging from 75 to 732 days after their LTs, and no procedure-related complications were encountered. In group B, the technical and long-term clinical success rates of PTBD were 50% and 25%, respectively. Three group B patients (75%) underwent PTBD within 30 days after LDLT and had lethal complications. One patient had graft laceration and survived after receiving timely re-transplantation. The other two patients died of sepsis due to PTBD-related bilioportal fistula or multiple liver abscesses. Our experience showed salvage PTBD played a limited role in biliary complications without dilated IHBDs within 1 month after LT.

Evaluation of retrootolithic function using galvanic vestibular-evoked myogenic potentials in patients with benign paroxysmal positional vertigo.

PURPOSE: The purpose is to investigate possible vestibulopathy in patients with benign paroxysmal positional vertigo (BPPV), inner ear tests, including cervical and ocular vestibular-evoked myogenic potentials (cVEMPs and oVEMPs) via various stimulation modes, were adopted. METHODS: Fifty BPPV patients were enrolled in this study. All patients underwent pure tone audiometry, cVEMPs, oVEMPs, and caloric tests. The recurrence status, abnormal rates of inner ear tests, and the characteristic parameters of VEMPs, such as wave latencies and amplitudes, were analyzed. RESULTS: In affected ears, the abnormal rates of acoustic cVEMPs, vibratory oVEMPs, galvanic cVEMPs, and galvanic oVEMPs were 62%, 28%, 36%, and 14%, respectively. The abnormalities of acoustic cVEMPs were significantly larger than those of vibratory oVEMPs, and acoustic/vibratory VEMPs had significantly higher abnormal rates than the corresponding galvanic VEMPs. CONCLUSION: BPPV patients may have both otolithic and neural dysfunctions. Otolithic organ damage occurs more frequently than retrootolithic neural degeneration, and the saccular macula might have a greater extent of damage than the utricular macula.

Efficacy of Povidone-Iodine Nasal Irrigation Solution After Sinonasal Surgery: A Randomized Controlled Study.

OBJECTIVES/HYPOTHESIS: To evaluate the efficacy of postoperative nasal irrigation with povidone-iodine (PVP-I) solution in patients undergoing sinonasal surgery. STUDY DESIGN: Single-blind, randomized controlled study. METHODS: This is a prospective, single-blind, randomized controlled study. Patients with chronic rhinosinusitis (CRS) and hypertrophic inferior turbinates who underwent endoscopic sinus surgery (ESS) and inferior turbinate reduction were enrolled in the study. Patients were evaluated using the Taiwanese version of the 22-item Sino-Nasal Outcome Test (TWSNOT-22), rhinomanometry, endoscopic examination, and bacterial cultures. One week after the operation, patients were randomly assigned to either a 0.1% PVP-I nasal irrigation group or a control (normal saline) irrigation group. We then compared the two groups' results to illustrate the effects of nasal irrigation with PVP-I solution following sinonasal surgery. RESULTS: Of the 55 patients that completed the study, 27 patients were in the PVP-I group and 28 were in the control group. In both groups, the TWSNOT-22 scores, Lund-Kennedy endoscopic scores, and total nasal resistance (TNR) all revealed significant improvements at 3 months postoperatively compared with preoperative measurements (all, P < .05). However, there were no significant differences between the two groups in TWSNOT-22, endoscopic, or TNR scores 3 months after the operation (all, P > .05). CONCLUSIONS: A dilute 0.1% PVP-I nasal irrigation as a postoperative care modality after sinonasal surgery did not provide additional benefit compared with normal saline irrigation.

The association between oral health status and the clinical outcome of cirrhotic patients on the waiting list for liver transplantation.

Liver transplantation (LT) candidates often present with poor oral hygiene, which could potentially lead to systemic infections and sepsis owing to their cirrhotic state. In this study, we investigated the oral health status of LT candidates and propose guidance for the detection and treatment of encountered oral lesions among these patients. The decayed, missing, and filled teeth (DMFT) index was determined through oral examination. The presence of dental calculus was detected using panoramic radiography and defined by the radiopaque dental calculus (RDC). From January 2011 to August 2018, 56 LT candidates were enrolled with a median follow-up of 39 months. The overall mean numbers of decayed, missing, and filled teeth among these patients were 2.7 ± 2.8, 10.9 ± 8.3, and 5.4 ± 4.5, respectively. Eighteen patients (32.1%) had RDC. The 5-year survival rates of all 56 patients was 57.7%, while that of those who either received LT (23 patients) or not were 82.1% and 39.8%, respectively. A Cox regression model revealed better overall survival of patients after LT (adjusted hazard ratio [aHR] = 0.067, p = 0.001), worse survival among patients with RDC (aHR = 3.468, p = 0.010), at Child-Pugh stages B and C (aHR for stage B = 11.889, p = 0.028; aHR for stage C = 19.257, p = 0.013) compared to patients at Child-Pugh stage A, and those with a model for end-stage liver disease (MELD) score ≥25 (aHR = 13.721, p = 0.018). This study demonstrates that RDC was associated with worse prognosis in LT candidates. We therefore recommend that interprofessional collaboration should be a routine preoperative procedure for the evaluation of oral hygiene among LT candidates.
