Effects of Fibrinogen Concentrate Supplementation on Postoperative Bleeding in Infants Undergoing Complex Cardiac Surgery.

The use of allogeneic blood products to restore hemostasis during pediatric cardiac surgery is associated with major risks. Consequently, there has been a growing interest in new patient blood management strategies, such as those based on the use of fibrinogen concentrate (FC). Accumulating evidence has shown FC supplementation to be safe and effective. Nevertheless, no guidelines are available on using FC in the pediatric setting, and few objective evaluations have been provided in clinical practice. The endpoint of this monocenter retrospective study was the hemostatic effect of additional FC in infants undergoing complex cardiac surgery with cardiopulmonary bypass to manage persistent clinically relevant bleeding. After weaning from cardiopulmonary bypass and after protamine administration, patients were transfused with conventional allogeneic products such as packed red blood cells, fresh frozen plasma (FFP), and platelets. In the case of redo surgery, according to the institutional protocol, patients also received tranexamic acid. In case of clinically persistent relevant bleeding, according to the anesthesiologist's judgment and thromboelastography, patients received FC supplementation (group with FC) or further FFP transfusions without receiving FC supplementation (group without FC). The primary endpoint was the hemostatic effects of FC. Secondary endpoints were the functional hypofibrinogenemia threshold value (expressed as maximum amplitude fibrinogen, MA-Fib) and postoperative MA-Fib, fibrinogenemia, intraoperative transfusions, and adverse events (AEs). In total, 139 patients who underwent cardiac surgery with CPB and aged less than 2 years were enrolled: 70 patients received allogeneic blood products and FC supplementation (group FC); 69 patients received allogeneic products without FC supplementation (group without FC). Patients that received FC supplementation were characterized by a significantly longer time of extracorporeal circulation (p < 0.001) and aortic cross-clamping (p < 0.001), a significantly lower minimum temperature (p = 0.011), increased use of concentrated prothrombin complex (p = 0.016) and tranexamic acid (p = 0.010), and a significantly higher amount of packed red blood cells, platelets (p < 0.001) and fresh frozen plasma (p = 0.03). Postoperative bleeding and severe bleeding were not statistically different between patients treated with FC and those not treated with FC supplementation (p = 0.786 and p = 0.695, respectively); after adjustment, a trend toward reduced bleeding can be observed with FC (p = 0.064). Overall, 88% of patients with severe bleeding had MA-Fib < 10 mm; a moderate association between severe bleeding and MA-Fib (odds ratio 1.7, 95% CI 0.5-6.5, p = 0.425) was found. Increased MA-Fib and postoperative fibrinogen were higher in the FC group (p = 0.003 and p < 0.001, respectively) than in FFP. AEs in the FC group were comparable to those observed in less complicated surgeries. Our results suggest a potential role of FC in complex surgery in maintaining postoperative bleeding at a level comparable to less complicated surgical procedures and favoring the increase in postoperative MA-Fib and fibrinogen.

Use of intensive care, intracranial pressure monitoring, and external ventricular drainage devises in patients with bacterial meningitis, a cohort study.

BACKGROUND: Bacterial meningitis can cause a life-threatening increase in intracranial pressure (ICP). ICP-targeted treatment including an ICP monitoring device and external ventricular drainage (EVD) may improve outcomes but is also associated with the risk of complications. The frequency of use and complications related to ICP monitoring devices and EVDs among patients with bacterial meningitis remain unknown. We aimed to investigate the use of ICP monitoring devices and EVDs in patients with bacterial meningitis including frequency of increased ICP, drainage of cerebrospinal fluid (CSF), and complications associated with the insertion of ICP monitoring and external ventricular drain (EVD) in patients with bacterial meningitis. METHOD: In a single-center prospective cohort study (2017-2021), we examined the frequency of use and complications of ICP-monitoring devices and EVDs in adult patients with bacterial meningitis. RESULTS: We identified 108 patients with bacterial meningitis admitted during the study period. Of these, 60 were admitted to the intensive care unit (ICU), and 47 received an intracranial device (only ICP monitoring device N = 16; EVD N = 31). An ICP > 20 mmHg was observed in 8 patients at insertion, and in 21 patients (44%) at any time in the ICU. Cerebrospinal fluid (CSF) was drained in 24 cases (51%). Severe complications (intracranial hemorrhage) related to the device occurred in two patients, but one had a relative contraindication to receiving a device. CONCLUSIONS: Approximately half of the patients with bacterial meningitis needed intensive care and 47 had an intracranial device inserted. While some had conservatively correctable ICP, the majority needed CSF drainage. However, two patients experienced serious adverse events related to the device, potentially contributing to death. Our study highlights that the incremental value of ICP measurement and EVD in managing of bacterial meningitis requires further research.

Longitudinal impact of multi-segment spinal fixation surgery on mobility status and clinical outcomes in adult spinal deformity: a multicenter retrospective study.

PURPOSE: To investigate changes in postoperative mobility status in patients with ASD, and the determining factors that influence these changes and their impact on clinical outcomes, including the rate of home discharge and long-term mobility. METHODS: A total of 299 patients with ASD who underwent multi-segment posterior spinal fusion were registered in a multi-center database were investigated. Patient mobility status was assessed using walking aids and classified into five levels (1: independent, 2: cane, 3: walker, 4: assisted, and 5: wheelchair) preoperatively, at discharge, and after 2 years. We determined improvements or declines in the patient's mobility based on changes in the classification levels. The analysis focused on the factors contributing to the deterioration of postoperative mobility. RESULTS: Two years postoperatively, 87% of patients maintained or improved mobility. However, 27% showed decreased mobility status at discharge, associated with a lower rate of home discharge (49% vs. 80% in the maintained mobility group) and limited improvement in mobility status (35% vs. 5%) after 2 years. Notably, postoperative increases in thoracic kyphosis (7.0 ± 12.1 vs. 2.0 ± 12.4°, p = 0.002) and lower lumbar lordosis (4.2 ± 13.1 vs. 1.8 ± 12.6°, p = 0.050) were substantial factors in mobility decline. CONCLUSION: Postoperative mobility often temporarily decreases but generally improves after 2 years. However, an overcorrection in sagittal alignment, evidenced by increased TK, could detrimentally affect patients' mobility status. Transient mobility decline associated with overcorrection may require further rehabilitation or hospitalization. Further studies are required to determine the biomechanical effects of surgical correction on mobility.

Bile duct diffusion-weighted image hyperintensity predicts intrahepatic biliary complications after ABO-incompatible liver transplantation.

OBJECTIVES: We assessed the value of the diffusion-weighted image (DWI) for predicting intrahepatic biliary complications (IHBC) after ABO-incompatible liver transplantation (ABOi-LT), potentially leading to refractory cholangitis. MATERIALS AND METHODS: In this retrospective study at a single center, 56 patients who underwent ABOi-LT from March 2021 to January 2023 were analyzed. All received magnetic resonance cholangiopancreatography (MRCP) and DWI during the postoperative hospitalization. MRCP findings, including bile duct DWI hyperintensity, were assessed. Participants suspected of having a biliary infection or obstructive jaundice underwent endoscopic retrograde cholangiopancreatography (ERCP) or percutaneous transhepatic biliary drainage (PTBD) during the follow-up. Non-anastomotic biliary strictures on cholangiography were classified as IHBC, as either perihilar or diffuse form. DWI hyperintensity was compared between groups with and without IHBC. Logistic regression analysis was performed to identify independent risk factors for IHBC. RESULTS: Of the 55 participants (median age 55 years, 39 males), IHBC was diagnosed in eight patients over a median follow-up of 15.9 months (range 5.6-31.1). Bile duct DWI hyperintensity was observed in 18 patients. Those with DWI hyperintensity exhibited a higher IHBC incidence (6/18, 33.3% vs. 2/36, 5.6%; p = 0.01), and more frequently developed the diffuse type IHBC (4/18, 22.2% vs. 1/36, 2.8%; p = 0.04). Regression analysis indicated that bile duct DWI hyperintensity is an independent risk factor for IHBC (odds ratio (OR) 10.1; 95% confidence interval (CI) 1.4, 71.2; p = 0.02) and its diffuse form (OR 15.3; 95% CI 1.2, 187.8; p = 0.03). CONCLUSION: Postoperative DWI hyperintensity of bile ducts can serve as a biomarker predicting IHBC after ABOi-LT. CLINICAL RELEVANCE STATEMENT: Postoperative diffusion-weighted image hyperintensity of the bile duct can be used as a biomarker to predict intrahepatic biliary complications and aid in identifying candidates who may benefit from additional management for antibody-mediated rejection. KEY POINTS: Intrahepatic biliary complications following ABO-incompatible liver transplantation can cause biliary stricture and biloma formation. Bile duct hyperintensity on early postoperative diffusion-weighted imaging was associated with increased intrahepatic biliary complication risk. This marker is an additional method for identifying individuals who require intensive management to prevent complications.

[Secondary defect coverage and functional reconstruction]. / Sekundäre Defektdeckung und funktionelle Rekonstruktion.

Secondary reconstruction in trauma surgery is crucial for restoring both functional and esthetic results in patients with complex defects. Established reconstructive techniques in plastic surgery offer a wide range of options for an effective treatment. This applies not only to covering large defects with free flaps but especially also for the functional reconstruction of bony, neural and musculotendinous impairments. Advances in the fields of microsurgery and 3D printing show innovative approaches to further improve the therapeutic options. A multidisciplinary approach, requiring close collaboration between trauma and plastic surgeons, is necessary to optimize treatment plans and outcomes. The effective management of complications and qualified postoperative care are essential for the success of reconstructive measures.

Current advances in the use of artificial intelligence in predicting and managing urological complications.

BACKGROUND: Artificial intelligence (AI) has emerged as a promising avenue for improving patient care and surgical outcomes in urological surgery. However, the extent of AI's impact in predicting and managing complications is not fully elucidated. OBJECTIVES: We review the application of AI to foresee and manage complications in urological surgery, assess its efficacy, and discuss challenges to its use. METHODS AND MATERIALS: A targeted non-systematic literature search was conducted using the PubMed and Google Scholar databases to identify studies on AI in urological surgery and its complications. Evidence from the studies was synthesised. RESULTS: Incorporating AI into various facets of urological surgery has shown promising advancements. From preoperative planning to intraoperative guidance, AI is revolutionising the field, demonstrating remarkable proficiency in tasks such as image analysis, decision-making support, and complication prediction. Studies show that AI programmes are highly accurate, increase surgical precision and efficiency, and reduce complications. However, implementation challenges exist in AI errors, human errors, and ethical issues. CONCLUSION: AI has great potential in predicting and managing surgical complications of urological surgery. Advancements have been made, but challenges and ethical considerations must be addressed before widespread AI implementation.

The effect of BIS-guided anaesthesia on the incidence of postoperative nausea and vomiting in children: a prospective randomized double-blind study.

BACKGROUND: Postoperative nausea and vomiting (PONV) is a significant problem following paediatric surgery, and volatile anaesthetics are an important cause of this phenomenon. BIS-guided anaesthesia, by reducing the consumption of anaesthetics, leads to a decrease in PONV in adult patients. STUDY OBJECTIVE: Evaluate the role of BIS-guided anaesthesia in reducing the incidence of paediatric PONV. DESIGN: Prospective, randomized, double-blind study. SETTING: A single center study in university hospital in Czech republic, from June 2021 to November 2022. PATIENTS: A total of 163 children, aged 3-8 years with ASA I-II who underwent endoscopic adenoidectomy under general anaesthesia were included. INTERVENTIONS: In the intervention group, the depth of anaesthesia was maintained to values between 40 and 60 of BIS. MAIN OUTCOME MEASURE: The primary outcome was the incidence of postoperative nausea and vomiting during 24 h after surgery. RESULTS: The use of BIS-guided anaesthesia led to a significant decrease in the incidence of nausea and vomiting compared to the control group [17% vs. 53%; RR (95%CI) 0.48 (0.27-0.86); p < 0.001and 16% vs. 34%; RR (95%CI) 0.33 (0.20-0.54); p = 0.01, respectively]. CONCLUSIONS: BIS-guided anaesthesia decreases the incidence of postoperative nausea and vomiting in children undergoing adenoidectomy. TRIAL REGISTRATION: Clinicaltrials.gov identifier: NCT04466579.

Clinical Efficacy and Safety Meta-Analysis of Different Surgical Approaches for Female Stress Urinary Incontinence.

OBJECTIVE: Meta-analysis was conducted to compare and evaluate the efficacy and safety of tension-free vaginal tape (TVT), outside-in trans-obturator tape (TOT), inside-out tension-free vaginal tape-obturator (TVT-O) and transvaginal tension-free urethral sling surgery (TVT-S) in the treatment of female stress urinary incontinence (SUI). METHODS: A computer-based systematic search of the PubMed, The Cochrane Library, Medline, Embase, Web of Science and ScienceDirect databases for randomised controlled trials (RCTs) comparing TVT, TOT, TVT-O and TVT-S for the treatment of SUI was performed from the time of library construction to November 2023. Two investigators performed data extraction and quality evaluation of the included RCTs, extracting information including the follows: First author, time of publication, intervention, sample size, age, duration of follow-up and objective cure rate, subjective cure rate, dyspareunia, vaginal mucosal perforation, urinary tract infection, sling exposure and postoperative thigh pain/groin pain. Review Manager (RevMan) 5.4 was used for data processing. RESULTS: A total of 14 RCTs with 2665 patients were included. Meta-analysis showed no statistically significant differences in objective cure rate, urinary tract infection, sling exposure and postoperative thigh pain/groin pain. The subjective cure rate of TVT was higher than that of TOT (odds ratio (OR), 95% confidence interval (CI) = 1.37 (1.02, 1.84), p = 0.03); The incidence of TVT-O voiding difficulty was lower than that of TVT (OR, 95% CI = 2.94 (1.20, 7.20), p = 0.02); And the incidence of vaginal mucosal perforation of TOT was lower than that of TVT (OR, 95% CI = 0.11 (0.02, 0.61), p = 0.01). CONCLUSIONS: The four surgical procedures, TVT, TOT, TVT-O and TVT-S, were relatively similar in terms of SUI outcomes. TVT had a higher subjective cure rate than TOT and a higher incidence of postoperative dyspareunia and vaginal mucosal perforation.

Differences in Clinical Outcomes between One-Stage and Staged Flexible Ureteroscopy for the Treatment of Upper Urinary Tract Stones.

OBJECTIVE: Upper urinary tract stones (UUTSs) are among the most common types of urinary stones, and their incidence rate has been increasing annually in recent years, seriously affecting the daily lives of patients. This study aimed to compare the treatment efficacy of one-stage and staged flexible ureteroscopic lithotripsy (FURL) for UUTSs. METHODS: A total of 142 patients with UUTSs admitted to our hospital between December 2019 and March 2023 were selected for retrospective analysis, including 76 patients who received staged FURL (control group) and 66 patients who received one-stage FURL (observation group). The duration of surgery, length of stay, stone clearance rate, incidence of postoperative complications (from postsurgery to discharge), and total hospitalization cost were analyzed in both groups. The visual analog scale (VAS) score and activities of daily living (ADL) score were assessed before surgery (T0), 3 days after surgery (T1), and 7 days after surgery (T2). Patients were followed up for 1 month after surgery, and their quality of life was assessed using the MOS Item Short Form Health Survey (SF-36). RESULTS: There was no difference in the stone clearance rate or incidence of postoperative complications between the two groups (p > 0.05). The operation time, hospitalization time and hospitalization cost in the observation group were 75.58 ± 15.91 min, 4.20 ± 1.24 days and 14312.62 ± 1078.89 yuan, respectively, which were lower than those in the control group (p < 0.05). In addition, the VAS score at T3 was decreased to 1.49 ± 0.70, while the ADL and SF-36 scores were higher in the observation group (p < 0.05). CONCLUSIONS: One-stage FURL shortens the duration of surgery and length of stay, reduces hospitalization costs, and improves the quality of life of patients with UUTSs.

Diaphragmatic dysfunction is associated with postoperative pulmonary complications in the aged patients underwent radical resection of esophageal cancer: a prospective observational study.

Background: Diaphragmatic dysfunction escalates the susceptibility to postoperative pulmonary complications (PPCs). Currently, no study reports the occurrence of diaphragmatic dysfunction correlated with PPCs following radical resection of esophageal cancer in aged patients. We aimed to diagnose diaphragmatic dysfunction via ultrasonography and analyze diaphragmatic dysfunction's relation with PPCs after radical resection of esophageal cancer surgery in aged patients. Methods: This prospective observational study comprised 86 aged patients undergoing radical resection of esophageal cancer. Patient characteristics data and intraoperative details were collected. Ultrasonography was performed before (preoperative) and after (first, third, and fifth day postoperatively) surgery. Outcome measures included PPCs within seven days postoperative, occurrence of diaphragmatic dysfunction, and short-term prognosis. Results: After excluding 14 patients, we finally analyzed clinical data from 72 patients. The prevalence of PPCs was higher in the patients with diaphragmatic dysfunction than those without (19 of 23, 83% vs. 21 of 49, 43%, P=0.004). Postoperative diaphragmatic dysfunction was positively correlated with PPCs in patients who underwent elective radical esophageal cancer surgery (r=0.37, P=0.001). Persistent diaphragmatic dysfunction, furthermore, was positively correlated with the development of multiple PPCs (r=0.43, P<0.001). The logistic regression analysis revealed that age, total open procedure, and postoperative diaphragmatic dysfunction were identified as significant risk factors for PPCs, while total open procedure was an independent risk factor for diaphragmatic dysfunction. Conclusions: Postoperative diaphragmatic dysfunction positively correlates with developing PPCs. Continuous monitoring of postoperative diaphragmatic function can screen high-risk patients with PPCs, which has specific clinical significance. Age, total open procedure, and diaphragmatic dysfunction are identified as risk factors for developing PPCs, while total open procedure specifically increases the risk for postoperative diaphragmatic dysfunction.

Construction and validation of a risk prediction model for postoperative delirium in patients with off­pump coronary artery bypass grafting.

Background: Compared with cardiopulmonary bypass surgery, off-pump coronary artery bypass grafting (OPCABG) reduces trauma to the body. However, there is still a risk of neurological complications, including postoperative delirium (POD). To date, few studies have been conducted on the risk of POD in OPCABG patients, and no standardized prediction model has been established. Thus, this study sought to analyze the factors influencing POD in OPCABG patients and to construct a risk prediction model. Methods: A total of 1,258 patients with OPCABG were enrolled and divided into the training set for model construction (944 cases) and the test set for model validation (314 cases). A risk prediction model for POD in OPCABG patients was established by least absolute shrinkage and selection operator (LASSO) regression and multivariate logistic regression, and a nomogram was drawn. The discrimination and calibration degree of the model was evaluated by the receiver operator characteristic (ROC) curve and calibration curve. Results: Eight variables [i.e., age, tissue oxygen saturation, mean arterial pressure (MAP), carotid stenosis, the anterior-posterior diameter of the aortic sinus, ventricular septum thickness, left ventricular ejection fraction (LVEF), and Mini-Mental State Examination (MMSE) scores] were screen out by the LASSO regression and multivariate logistic regression, and the model was constructed. The area under the ROC curve of the training set was 0.702 [95% confidence interval (CI): 0.662-0.743], and that of the test set was 0.658 (95% CI: 0.585-0.730). The results of the Hosmer-Lemeshow goodness-of-fit test showed that the predicted POD risk of OPCABG patients in the training and test sets was consistent with the actual POD risk (χ2=5.154, P=0.74). Conclusions: The occurrence of POD in OPCABG patients is related to age, tissue oxygen saturation, MAP, carotid artery stenosis, the anterior-posterior diameter of aortic sinus, ventricular septal thickness, LVEF, and MMSE scores. The prediction model constructed with the above variables had high predictive performance, and thus may be helpful in the early identification of such patients.

Prognostic significance of immunotherapy in postoperative recurrent non-small cell lung cancer without EGFR mutations or ALK rearrangements.

Background: Limited reports exist regarding postoperative recurrent non-small cell lung cancer (NSCLC) without major driver mutations [epidermal growth factor receptor (EGFR) mutations or anaplastic lymphoma kinase (ALK) rearrangements] treated with immune checkpoint inhibitors (ICIs) when programmed cell death ligand 1 (PD-L1) is expressed in a real-world setting. The aim of this study was to evaluate the effect of ICIs for those NSCLC. Methods: We enrolled 255 patients with postoperative recurrent NSCLC lacking EGFR mutations or ALK rearrangements who underwent lobectomy or more extensive resection between 2012 and 2021. Factors associated with post-recurrence survival (PRS) were determined using the Cox proportional hazards model. PRS was analyzed using Kaplan-Meier curves and compared using the log-rank test. Results: Multivariable analysis demonstrated that squamous cell carcinoma, pathological stage III, and an Eastern Cooperative Oncology Group (ECOG) performance status ≥2 were significantly associated with worse PRS. Conversely, ICI use at first line was associated with improved PRS. Patients who used ICIs during the first line and subsequent therapies had better PRS than those who received chemotherapy alone. Among patients who used ICIs, there was no significant difference in response rate at the first line, nor in PRS among those with PD-L1 expression ≥50%, 1-49%, and <1% in surgically resected specimens. Conclusions: ICI use at any treatment line improved the PRS of NSCLC patients without major driver mutations, irrespective of PD-L1 expression, in a real-world setting.

Preoperative respiratory assessment predicts post-operative survival in stage IA non-small cell lung cancer.

Background: Respiratory impairment can lead to pulmonary complications after surgery; therefore, it should be considered when determining the choice of surgical procedure. Several studies have examined the relationship between preoperative respiratory function and postoperative mortality and morbidity after lung resection; however, there are no indicators for limited surgical procedure selection. The aim of this study was to examine the association between preoperative respiratory function and postoperative early and late complications, recurrence-free survival (RFS), and overall survival (OS) in patients undergoing pulmonary resection for stage I lung cancer. Methods: We performed a retrospective analysis of data from 192 patients undergoing pulmonary resection for primary pathological stage IA non-small cell lung cancer (NSCLC) at the Iwakuni Clinical Center in Japan between 2012 and 2015. We reviewed clinicopathological characteristics including preoperative pulmonary function and elucidated the relationship between them and postoperative survival. Results: Obstructive ventilatory impairment was present in 55 patients (28.6%), and restrictive ventilatory impairment was present in 31 patients (16.1%). Seven patients (3.6%) had both ventilatory impairment. Obstructive ventilatory impairment did not affect the 5-year RFS (P=0.08) or OS (P=0.21). However, restrictive ventilatory impairment reduced the 5-year RFS (P=0.002) and OS (P=0.009). The rates of early and late complications were not significantly different based on the preoperative respiratory function. Conclusions: In patients with preoperative restrictive ventilatory impairment in whom lobectomy or segmentectomy cannot be performed, careful consideration is needed for surgical indications.

Influence of reduced-port laparoscopic surgery on perioperative indicators, postoperative recovery, and serum inflammation in patients with colorectal carcinoma.

BACKGROUND: Conventional five-port laparoscopic surgery, the current standard treatment for colorectal carcinoma (CRC), has many disadvantages. AIM: To assess the influence of reduced-port laparoscopic surgery (RPLS) on perioperative indicators, postoperative recovery, and serum inflammation indexes in patients with CRC. METHODS: The study included 115 patients with CRC admitted between December 2019 and May 2023, 52 of whom underwent conventional five-port laparoscopic surgery (control group) and 63 of whom underwent RPLS (research group). Comparative analyses were performed on the following dimensions: Perioperative indicators [operation time (OT), incision length, intraoperative blood loss (IBL), and rate of conversion to laparotomy], postoperative recovery (first postoperative exhaust, bowel movement and oral food intake, and bowel sound recovery time), serum inflammation indexes [high-sensitivity C-reactive protein (hs-CRP), tumor necrosis factor-α (TNF-α), and interleukin-6 (IL-6)], postoperative complications (anastomotic leakage, incisional infection, bleeding, ileus), and therapeutic efficacy. RESULTS: The two groups had comparable OTs and IBL volumes. However, the research group had a smaller incision length; lower rates of conversion to laparotomy and postoperative total complication; and shorter time of first postoperative exhaust, bowel movement, oral food intake, and bowel sound recovery; all of which were significant. Furthermore, hs-CRP, IL-6, and TNF-α levels in the research group were significantly lower than the baseline and those of the control group, and the total effective rate was higher. CONCLUSION: RPLS exhibited significant therapeutic efficacy in CRC, resulting in a shorter incision length and a lower conversion rate to laparotomy, while also promoting postoperative recovery, effectively inhibiting the inflammatory response, and reducing the risk of postoperative complications.

Endoscopic ultrasound-guided biliary drainage vs percutaneous transhepatic bile duct drainage in the management of malignant obstructive jaundice.

BACKGROUND: Malignant obstructive jaundice (MOJ) is a condition characterized by varying degrees of bile duct stenosis and obstruction, accompanied by the progressive development of malignant tumors, leading to high morbidity and mortality rates. Currently, the two most commonly employed methods for its management are percutaneous transhepatic bile duct drainage (PTBD) and endoscopic ultrasound-guided biliary drainage (EUS-BD). While both methods have demonstrated favorable outcomes, additional research needs to be performed to determine their relative efficacy. AIM: To compare the therapeutic effectiveness of EUS-BD and PTBD in treating MOJ. METHODS: This retrospective analysis, conducted between September 2015 and April 2023 at The Third Affiliated Hospital of Soochow University (The First People's Hospital of Changzhou), involved 68 patients with MOJ. The patients were divided into two groups on the basis of surgical procedure received: EUS-BD subgroup (n = 33) and PTBD subgroup (n = 35). Variables such as general data, preoperative and postoperative indices, blood routine, liver function indices, myocardial function indices, operative success rate, clinical effectiveness, and complication rate were analyzed and compared between the subgroups. RESULTS: In the EUS-BD subgroup, hospital stay duration, bile drainage volume, effective catheter time, and clinical effectiveness rate were superior to those in the PTBD subgroup, although the differences were not statistically significant (P > 0.05). The puncture time for the EUS-BD subgroup was shorter than that for the PTBD subgroup (P < 0.05). Postoperative blood routine, liver function index, and myocardial function index in the EUS-BD subgroup were significantly lower than those in the PTBD subgroup (P < 0.05). Additionally, the complication rate in the EUS-BD subgroup was lower than in the PTBD subgroup (P < 0.05). CONCLUSION: EUS-BD may reduce the number of punctures, improve liver and myocardial functions, alleviate traumatic stress, and decrease complication rates in MOJ treatment.

Correlation between postoperative chemotherapy regimen and survival in patients with resectable gastric adenocarcinoma accompanied with vascular cancer thrombus.

BACKGROUND: Patients with resectable gastric adenocarcinoma accompanied by vascular cancer thrombus (RGAVCT) have a poor prognosis, with a 5-year survival rate ranging from 18.42%-53.57%. These patients need a reasonable postoperative treatment plan to improve their prognosis. AIM: To determine the most effective postoperative chemotherapy regimen for patients with RGAVCT. METHODS: We retrospectively collected the clinicopathological data of 530 patients who underwent radical resection for gastric cancer between January 2017 and January 2022 and who were pathologically diagnosed with gastric adenocarcinoma with a choroidal cancer embolus. Furthermore, we identified the high-risk variables that can influence the prognosis of patients with RGAVCT by assessing the clinical and pathological features of the patients who met the inclusion criteria. We also assessed the significance of survival outcomes using Mantel-Cox univariate and multivariate analyses. The subgroups of patients with stages I, II, and III disease who received single-, dual-, or triple-drug regimens following surgery were analyzed using SPSS 25.0 and the ggplot2 package in R 4.3.0. RESULTS: In all, 530 eligible individuals with RGAVCT were enrolled in this study. The median overall survival (OS) of patients with RGAVCT was 24 months, and the survival rates were 80.2%, 62.5%, and 42.3% at 12, 24, and 59 months, respectively. Preoperative complications, tumor size, T stage, and postoperative chemotherapy were identified as independent factors that influenced OS in patients with RGAVCT according to the Cox multivariate analysis model. A Kaplan-Meier analysis revealed that chemotherapy had no effect on OS of patients with stage I or II RGAVCT; however, chemotherapy did have an effect on OS of stage III patients. Stage III patients who were treated with chemotherapy consisting of dual- or triple-agent regimens had better survival than those treated with single-agent regimens, and no significant difference was observed in the survival of patients treated with chemotherapy consisting of dual- or triple-agent regimens. CONCLUSION: For patients with stage III RGAVCT, a dual-agent regimen of postoperative chemotherapy should be recommended rather than a triple-agent treatment, as the latter is associated with increased frequency of adverse events.

Sarcopenia adversely impacts clinical outcomes in patients undergoing pancreaticoduodenectomy: A systematic review and meta-analysis.

BACKGROUND: Sarcopenia is a syndrome marked by a gradual and widespread reduction in skeletal muscle mass and strength, as well as a decline in functional ability, which is associated with malnutrition, hormonal changes, chronic inflammation, disturbance of intestinal flora, and exercise quality. Pancreatoduodenectomy is a commonly employed clinical intervention for conditions such as pancreatic head cancer, ampulla of Vater cancer, and cholangiocarcinoma, among others, with a notably high rate of postoperative complications. Sarcopenia is frequent in patients undergoing pancreatoduodenectomy. However, data regarding the effects of sarcopenia in patients undergoing pancreaticoduodenectomy (PD) are both limited and inconsistent. AIM: To assess the influence of sarcopenia on outcomes in patients undergoing PD. METHODS: The PubMed, Cochrane Library, Web of Science, and Embase databases were screened for studies published from the time of database inception to June 2023 that described the effects of sarcopenia on the outcomes and complications of PD. Two researchers independently assessed the quality of the data extracted from the studies that met the inclusion criteria. Meta-analysis using RevMan 5.3.5 and Stata 14.0 software was conducted. Forest and funnel plots were used, respectively, to demonstrate the outcomes of the sarcopenia group vs the non-sarcopenia group after PD and to evaluate potential publication bias. RESULTS: Sixteen studies encompassing 2381 patients were included in the meta-analysis. The patients in the sarcopenia group (n = 833) had higher overall postoperative complication rates [odds ratio (OR) = 3.42, 95% confidence interval (CI): 1.95-5.99, P < 0.0001], higher Clavien-Dindo class ≥ III major complication rates (OR = 1.41, 95%CI: 1.04-1.90, P = 0.03), higher bacteremia rates (OR = 4.46, 95%CI: 1.42-13.98, P = 0.01), higher pneumonia rates (OR = 2.10, 95%CI: 1.34-3.27, P = 0.001), higher pancreatic fistula rates (OR = 1.42, 95%CI: 1.12-1.79, P = 0.003), longer hospital stays (OR = 2.86, 95%CI: 0.44-5.28, P = 0.02), higher mortality rates (OR = 3.17, 95%CI: 1.55-6.50, P = 0.002), and worse overall survival (hazard ratio = 2.81, 95%CI: 1.45-5.45, P = 0.002) than those in the non-sarcopenia group (n = 1548). However, no significant inter-group differences were observed regarding wound infections, urinary tract infections, biliary fistulas, or postoperative digestive bleeding. CONCLUSION: Sarcopenia is a common comorbidity in patients undergoing PD. Patients with preoperative sarcopenia have increased rates of complications and mortality, in addition to a poorer overall survival rate and longer hospital stays after PD.

A retrospective study on the efficacy of the ERAS protocol in patients who underwent laparoscopic left and right colectomy surgeries.

Objective: Retrospective analysis and comparison of the effects of Enhanced Recovery After Surgery (ERAS) protocol for patients having left and right colectomy surgeries. Method: Out of the patients admitted to Chengdu Shang Jin Nan Fu Hospital and West China Hospital from December 2019 to December 2022, a total of 498 who met the inclusion criteria were selected, 255 with right colectomy(RC) and 243 with left colectomy (LC). Under the conditions of strict compliance with ERAS protocol, the relevant physical indexes of RC and LC, including postoperative rehabilitation (especially median post-operative stay) and complications (especially prolonged postoperative ileus, PPOI), were statistically analyzed and compared. Results: In terms of intraoperative variables, fluid doses were higher in the LC group than in the RC group (P < 0.05), and there was no significant difference between them in terms of operative time, blood loss, need for open surgery, peritoneal contamination, epidural catheter placement, or opioid use (P > 0.05). Compared with the RC group, the LC group had a higher intake of oral liquid at the second postoperative day (POD), and faster first flatulence (P < 0.05). 30 (11.76%) RC patients required nasogastric tube insertion, while only 3 (1.23%) patients in the LC group required the same (P < 0.05). Prolonged postoperative ileus (PPOI) occurred in 48 (18.82%) and 29 (11.93%) patients in the RC and LC groups, respectively (P < 0.05). No significant differences in terms of postoperative complications or length of hospital stay (LoS). stay were observed. Conclusion: As the location of colon cancer changes, the effectiveness of ERAS also varies. More personalized and precise ERAS protocols can reduce the incidence of postoperative complications and promote rapid recovery after surgery.

Postoperative outcomes of third-generation shoulder hemiarthroplasties for three-and four-part proximal humeral fractures: A systematic review of published studies from 2012 to 2022.

Background: The aim of this study was to provide up-to-date evidence on the outcomes for hemiarthroplasties (HAs) that were performed using modern third-generation prostheses (post-2004) for isolated (excluding head-splits and fracture-dislocations) three-and four-part proximal humerus fractures (PHFs). Methods: PubMed, Medline, Embase and the Cochrane register were searched from January 1, 2012, to November 15, 2022, conforming to the PRISMA guidelines. The outcome measures were the complication rates, revision rates, surgery-related postoperative mortality, post-operative clinical outcome scores and radiological outcomes. Results: 432 hemiarthroplasties in 432 patients were performed across the 11 eligible studies (two prospective and 9 retrospective). Three studies compared HA versus reverse shoulder replacement (RSR); one study compared HA with locking plate fixation (LPF) and RSR; one study compared HA with LPF. 61.1 % and 19.4 % of hemiarthroplasties were performed using cemented and uncemented techniques respectively, while cementing data was ill-defined in 19.4 % of shoulders. The results for the outcome measures have been derived directly from the included studies and no statistical pooling was performed, due to heterogeneity in the different study designs and outcomes. Descriptive data synthesis from the included studies showed that third generation HAs have higher overall postoperative complication rates, with similar revision and mortality rates when compared to RSR and LPF for three-and four-part PHFs. RSR and LPF showed better statistically significant improvements than HA for the Constant-Murley score, Quick DASH, forward flexion and abduction. Mixed results were observed for the DASH score, ASES score and internal rotation ROM between RSR/LPF versus HA. Conclusion: Low to moderate quality evidence from this review showed that even third-generation HA prostheses provided worse overall outcomes than RSR and LPF for three-and four-part PHFs.
