With advancements in implant materials and design, this procedure has seen rapid adoption and widespread use in ophthalmology clinics in recent years. However, the changes in surgical techniques and the occurrence of postoperative complications have raised safety concerns that require significant attention in clinical practice. This paper aims to address the key factors influencing the safety of posterior chamber phakic intraocular lens implantation, exploring relevant characteristics, mechanisms, and current challenges. By emphasizing the importance of this surgery and proposing effective measures, it aims to provide guidance for clinical practice, enhance the safety of posterior chamber phakic intraocular lens implantation, and foster the healthy advancement of this surgical technique.

[Efficacy of alternate mucosa-submucosa clip closure in preventing postoperative complications for patients with gastric mucosal lesions after endoscopic submucosal dissection].

Objective: To analyze the efficacy of alternate titanium clip closure in preventing postoperative complications for patients with gastric mucosal lesions after endoscopic submucosal dissection (ESD). Methods: Clinical data of patients with gastric mucosal lesions who underwent ESD in the Department of Gastroenterology, Zhongda Hospital, Southeast University, were retrospectively collected from January 1, 2013 to August 31, 2023. According to the postoperative wound closure status, the patients were divided into completely closed group (complete closure of ESD wounds using alternate titanium clip closure), partially closed group (partial closure of ESD wounds), and unclosed group (without use of clips for treatment of ESD wounds). The incidence of postoperative complications as well as wound healing at 1 month and 3 months after surgery were compared among three groups, and the factors related to delayed bleeding after ESD for gastric mucosal lesions were analyzed through multiple logistic regression analysis. Results: A total of 846 patients were included, 430 cases in the completely closed group, including 300 males and 130 females, age [M (Q1, Q3)] was 65(56, 72) years old; one hundred and nine cases in unclosed group, including 78 males and 31 females, aged 66 (60, 71) years; and 307 cases in the partially closed group, including 214 males and 93 females, aged 66 (59, 71) years. The difference in the rate of delayed postoperative bleeding between the completely closed group [2.1% (9/430)] and the unclosed group [5.5% (6/109)] was not statistically significant (P=0.072), but both were lower than that of the partially closed group [9.4% (29/307), P<0.05)]. Further stratified analysis showed that, for the lesions located in the lower 1/3 of the stomach, the rate of postoperative bleeding was lower in the completely closed group than in the partially closed and unclosed groups [0.9% (2/222) vs 11.4% (4/35) vs 9.5% (7/74), respectively, P<0.001]. For lesions≥50 mm in length, the rate of postoperative bleeding was lower in the completely closed group than that in the partially closed and unclosed group[0 vs 11.8% (2/17) vs 20.5% (15/73), respectively, P=0.004]. The incidence of postoperative abdominal pain in the completely closed group [84.2% (363/430)] was lower than that in the unclosed group [97.2% (106/109)] and the partially closed group [95.4% (293/307), both P<0.001)]. The score of postoperative abdominal pain in the completely closed group [0 (0, 1)], was lower than that in the unclosed group [3 (2, 3)], and that in the partially closed group [2 (1, 3)] (both P<0.001). The wound healing rate of the completely closed group [80% (176/220)] was higher than that of the unclosed group [52.3% (33/63)] and the partially closed group [52.2% (83/159)] at 1 month postoperatively (both P<0.001); the healing rate of all three groups reached 100% at 3 months postoperatively. Multiple logistic regression analysis showed that the presence of ulcers or scars on the surface of the lesion (OR=2.930, 95%CI:1.503-5.712, P=0.002), and the diameter (OR=1.031, 95%CI:1.015-1.047,P<0.001) were related factors for postoperative bleeding. Conclusions: The alternate titanium clip closure surgery can reduce postoperative abdominal pain and shorten wound healing time in patients with gastric mucosal lesions after ESD surgery. The risk of postoperative bleeding can be reduced for lesions with a diameter≥50 mm and located in the lower 1/3 of the stomach.

Delayed epistaxis after endoscopic transnasal pituitary tumor resection: clinical characteristics, risk factors, treatment and prevention.

BACKGROUND: Delayed epistaxis after endoscopic transnasal pituitary tumor resection (ETPTR) is a critical complication, tending to cause aspiration or hemorrhagic shock. This study assessed clinical characteristics, risk factors, and provide treatment and prevention advice of this complication. METHODS: This was a retrospective monocentric analysis of 862 patients who underwent ETPTR. Statistical analyses of clinical data revealed the incidence, sources and onset time of delayed epistaxis. Univariate analysis and binary logistic regression were used to identify risk factors. RESULTS: The incidence of delayed epistaxis was 2.78% (24/862), with an average onset time of 20.71 ± 7.39 days. The bleeding sources were: posterior nasal septal artery branch of sphenopalatine artery (12/24), multiple inflammatory mucosae (8/24), sphenopalatine artery trunk (3/24) and sphenoid sinus bone (1/24). Univariate analysis and binary logistic regression analysis confirmed that hypertension, nasal septum deviation, chronic rhinosinusitis and growth hormone pituitary tumor subtype were independent risk factors for delayed epistaxis. Sex, age, history of diabetes, tumor size, tumor invasion and operation time were not associated with delayed epistaxis. All patients with delayed epistaxis were successfully managed through endoscopic transnasal hemostasis without recurrence. CONCLUSIONS: Delayed epistaxis after ETPTR tends to have specific onset periods and risk factors. Prevention of these characteristics may reduce the occurrence of delayed epistaxis. Endoscopic transnasal hemostasis is recommended as the preferred treatment for delayed epistaxis.

Probiotic use in pediatric kidney transplant recipients: What are current practices, and are they evidence-based? A pediatric nephrology research consortium study.

BACKGROUND: Probiotics are living microorganisms that may confer health benefits to their host if administered in sufficient quantities. However, data on the use of probiotics in transplant recipients are scarce. METHOD: This multi-center survey of pediatric nephrologists aimed to examine variations in practice regarding the use of probiotics in pediatric kidney transplant recipients. The survey was conducted via a 10-item questionnaire (developed in Survey Monkey) administered to pediatric nephrologists participating in the Pediatric Nephrology Research Consortium meeting in April 2023. RESULTS: Sixty-four pediatric nephrologists completed the survey. Twenty-seven (42.2%) respondents reported having prescribed probiotics to pediatric kidney transplant recipients. The primary reason for probiotic use was the treatment of antibiotic-associated diarrhea (n = 20), with other reasons including recurrent Clostridium difficile infection (n = 15), general gut health promotion (n = 12), recurrent urinary tract infections (n = 8), and parental request (n = 1). Of those who prescribed probiotics, 48.1% held them during periods of neutropenia and 14.8% during central venous line use. Of the 64 respondents, 20 reported the lack of safety data as a concern for using probiotics in kidney transplant recipients. CONCLUSION: Pediatric nephrologists are increasingly prescribing probiotics to pediatric kidney transplant recipients; nevertheless, substantial practice variations exist. The paucity of safety data is a significant deterrent to probiotic use in this population.

Evaluation of clopidogrel, hypercoagulability, and platelet count in dogs undergoing splenectomy for splenic masses.

Dogs that had splenectomy are predisposed to fatal thrombotic conditions, and thrombocytosis is a risk factor for post-splenectomy hypercoagulability. However, in veterinary medicine, there are no specific therapeutic approaches for managing this hypercoagulability. This study aimed to determine the preventive effect of clopidogrel on post-operative hypercoagulability during the first 2 weeks post-splenectomy in dogs with splenic masses. This study included 12 dogs that had splenectomy. Seven dogs received no treatment (group A), and five were treated with clopidogrel (group B). Clopidogrel was loaded at 10 mg/kg on day 2 and continued at 2 mg/kg until day 14. Blood samples were collected on the day of surgery and 2, 7, and 14 days after splenectomy in both groups. In group B, thromboelastography (TEG) was performed on the same days. In group A, there was significant elevation of platelet counts on days 7 (p = 0.007) and 14 (p = 0.001) compared to day 0. In group B, the platelet counts were significantly elevated on day 7 (p = 0.032) but no significant difference was found on day 14 compared to day 0. Platelet counts on day 14 were significantly higher in group A than in group B (p = 0.03). The lower platelet counts were correlated with alterations in TEG parameters, and no significant differences were found in the K and α-angle values at all postoperative assessment points compared to day 0. Our study suggests that clopidogrel may reduce post-operative thrombocytosis and hypercoagulability in dogs that undergo splenectomy for splenic masses.

A Comparison Between Fondaparinux Sodium and Low-Molecular-Weight Heparin in Preventing Patients Undergoing Hip Replacement from Deep Vein Thrombosis.

OBJECTIVES: Total hip arthroplasty (THA) is a highly successful and effective surgery for improving hip functions and relieving pain. However, the lower extremities are prone to deep vein thrombosis (DVT) and swelling after surgery, thereby delaying recovery. In this study, we investigated the preventive effects of fondaparinux sodium (FS) and low-molecular-weight heparin (LMWH) on DVT of the lower extremity after THA. METHODS: Firstly, 60 patients who underwent THA at the First Affiliated Hospital of Wannan Medical College from March 2020 to December 2020 were included. Next, the patients were randomly divided into an LMWH group (n = 30) and an FS group (n = 30). Then, the indexes related to DVT were compared between both groups. RESULTS: Specifically, the differences in baseline data, such as age, gender and body mass index (BMI), between the two groups were not statistically significant. The postoperative weight bearing time of patients in the FS group was much shorter than that in the LMWH group. CONCLUSION: Subcutaneous injection of FS not only exhibits superior effects to LMWH in preventing DVT after THA but also has a correlation with reducing the risk of thrombosis and improving patient symptoms.

Pelvic Floor Functional Exercise Improves Lower Urinary Tract Symptoms after Uterine Fibroid Surgery.

BACKGROUND: This study aims to determine the effect of pelvic floor function exercise on the improvement of lower urinary tract symptoms in patients with uterine fibroid surgery. METHODS: The clinical data of 188 patients who underwent uterine fibroid surgery in our hospital from February 2020 to December 2022 were retrospectively analysed. The patients were divided into a control group and an observation group according to the nursing methods recorded in the data. The observation group received targeted nursing combined with pelvic floor function exercise based on routine intervention. General demographic data, disease and surgery-related characteristics of the patients were collected. Propensity score matching was used to balance the baseline data of the two groups. Lower urinary tract symptoms, pelvic floor function, pelvic floor muscle strength and quality of life were compared between the two groups after matching. RESULTS: A total of 130 patients were included in the two groups, and their baseline data were not statistically significant. At 3 months after the operation, the total incidence of lower urinary tract symptoms in the observation group (10.77%) was lower than that in the control group (30.77%, p < 0.05). Before the intervention, the pelvic floor function, pelvic floor muscle strength and quality of life scores of the two groups were basically the same (p > 0.05). At 3 months after the operation, the pelvic floor function score of the observation group was lower than that of the control group, but the pelvic floor muscle strength index and quality of life score of the observation group were higher than those of the control group (p < 0.05). CONCLUSIONS: Targeted nursing combined with pelvic floor function exercise for patients with uterine fibroids surgery can prevent the occurrence of lower urinary tract symptoms and improve the pelvic floor function, pelvic floor muscle strength and quality of life of patients and is thus worthy of promotion.

Improvement of Mental Health and Quality of Life of Patients after Radical Prostatectomy through Continuous Nursing Based on Internet Technology: A Retrospective Study.

OBJECTIVE: Radical prostatectomy (RP) is one of the most effective methods used to cure localised prostate cancer, but the risk of postoperative biochemical recurrence persists. This study aims to analyse the effect of continuous nursing based on Internet technology on mental health and quality of life in patients undergoing RP. METHODS: The medical records of patients undergoing RP in our hospital from February 2021 to February 2023 were retrospectively analysed. From February 2021 to January 2022, 89 patients received routine postoperative nursing, and 85 cases were included in the reference group after excluding 4 patients who had missing clinical data. From February 2022 to February 2023, 86 patients received continuous nursing based on Internet technology, and 80 patients were classified as the observation group after 6 patients (5 patients with incomplete clinical data and 1 patient with cognitive impairment) were excluded. The Hospital Anxiety and Depression Scale (HADS) data were collected, and urinary control, incidence of complications, nursing satisfaction and 36-item short-form health survey (SF-36) were compared between the two groups. RESULTS: After management, patients in the observation group had lower Hospital Anxiety and Depression Scale-Anxiety (HADS-A) score, Hospital Anxiety and Depression Scale-Depression (HADS-D) score and postvoid residual (PVR) and higher maximum flow rate (Qmax) and detrusor pressure at the maximum flow rate (Pdet-Qmax) (p < 0.001) than those in the reference group. The observation group also had significantly lower incidence of complications (p < 0.05), higher scores of physiological function, physiological role, physical pain, general health, vitality, social function, emotional function and mental health (p < 0.01) and significantly higher total nursing satisfaction (p < 0.05). Prostate specific antigen (PSA) level was not significantly different between the two groups after management (p > 0.05). CONCLUSIONS: Continuous nursing based on Internet technology improves the psychological status and quality of life, reduces the occurrence of postoperative complications and obtains high clinical satisfaction for patients receiving RP.

Effect of Pelvic Floor Function Exercises Based on the ERAS Concept on Lower Urinary Tract Symptoms after Radical Hysterectomy for Cervical Cancer: A Retrospective Cohort Study.

OBJECTIVE: This study aimed to analyse the effect of pelvic floor function exercises based on the enhanced recovery after surgery (ERAS) concept on lower urinary tract symptoms after radical hysterectomy for cervical cancer. METHODS: The retrospective study was conducted using clinical data of patients admitted to our hospital from January 2021 to December 2022 and underwent radical hysterectomy for cervical cancer. In accordance with the nursing method, the patients were divided into the routine group (conventional care) and the ERAS pelvic floor function exercise group, for which ERAS concept-based pelvic floor function exercises were carried out on the basis of the former group. The confounders between the two groups were matched by propensity score, and the scores of urination, pelvic floor muscle strength, lower urinary tract symptoms and quality of life (QoL) were compared between the two groups after matching. RESULTS: A total of 180 patients were included in the study, of whom 60 patients were identified after propensity score matching, consisting of 30 patients each in the ERAS and routine groups. The baseline characteristics of the two groups were balanced, and the difference was not statistically significant (p > 0.05). Compared with the routine group, the observation group showed significantly shorter first spontaneous urination time, greater first urination volume (p < 0.05), better pelvic floor muscle strength, considerably lower urinary tract symptoms and better QoL at discharge and 3 months after discharge (p < 0.05). CONCLUSIONS: Pelvic floor function exercises based on the ERAS concept can relieve lower urinary tract symptoms, accelerate urination and improve pelvic floor muscle strength and QoL after radical hysterectomy for cervical cancer.

High-Degree Heart Block During Noncardiac Surgery Soon After Transcatheter Aortic Valve Replacement: A Case Report.

Patients undergoing transcatheter aortic valve replacement (TAVR) as a bridge to noncardiac surgery have improved outcomes. Older clinical trials concluded no increased risk of performing noncardiac surgery within 30 days of the TAVR procedure. Emerging evidence suggests patients with preexisting conduction abnormalities may require additional intervention to proceed safely with noncardiac surgery. More data are needed to clarify this clinical situation, especially for the anesthesiologist whose job is to mitigate risk for these patients. We present a patient who received a TAVR and suffered associated complications during subsequent surgery. We further discuss preventative measures and perioperative considerations for this patient population.

Epicardial placement of human placental membrane allografts in coronary artery bypass graft surgery is associated with reduced postoperative atrial fibrillation: a pilot study for a future multi-center randomized controlled trial.

BACKGROUND: Post-operative atrial fibrillation (POAF) occurs in up to 40% of patients following coronary artery bypass grafting (CABG) and is associated with a higher risk of stroke and mortality. This study investigates how POAF may be mitigated by epicardial placement of aseptically processed human placental membrane allografts (HPMAs) before pericardial closure in CABG surgery. This study was conducted as a pilot feasibility study to collect preliminary for a forthcoming multi-center randomized controlled trial. METHODS: This retrospective observational study of patients undergoing CABG surgery excluded patients with pre-operative heart failure, chronic kidney disease, or a history of atrial fibrillation. The "treatment" group (n = 24) had three HPMAs placed epicardially following cardiopulmonary bypass decannulation but before partial pericardial approximation and chest closure. The only difference in clinical protocol for the control group (n = 54) was that they did not receive HPMA. RESULTS: HPMA-treated patients saw a significant, greater than four-fold reduction in POAF incidence compared to controls (35.2-8.3%, p = 0.0136). Univariate analysis demonstrated that HPMA treatment was associated with an 83% reduction in POAF (OR = 0.17, p = 0.0248). Multivariable analysis yielded similar results (OR = 0.07, p = 0.0156) after controlling for other covariates. Overall length of stay (LOS) between groups was similar, but ICU LOS trended lower with HPMA treatment (p = 0.0677). Post-operative inotrope and vasopressor requirements were similar among groups. There was no new-onset post-operative heart failure, stroke, or death reported up to thirty days in either group. CONCLUSIONS: Epicardial HPMA placement can be a simple intervention at the end of CABG surgery that may provide a new approach to reduce post-operative atrial fibrillation by modulating local inflammation, possibly reducing ICU and hospital stay, and ultimately improving patient outcomes.

Effect of liver transplants with retrograde reperfusion on early postoperative recovery of liver function and its risk factors.

BACKGROUND: The purpose of this study was to investigate effect of liver Transplants (LT) with retrograde reperfusion on early postoperative recovery of liver function and its risk factors. METHODS: We conducted a retrospective analysis of clinical data from 136 liver transplantation (LT) patients at the 900th Hospital of the Chinese People's Liberation Army Joint Support Army, covering the period from January 2015 to January 2021. All participants provided informed consent, adhering to medical ethics guidelines. Patients were stratified into two groups based on the liver perfusion technique used: retrograde reperfusion (RTR, n = 108) and initial portal reperfusion (IPR, n = 28). Our study focused on a subset of 23 patients from each group to compare postoperative liver function recovery. The final analysis included 86 RTR and 28 IPR cases after excluding 8 RTR patients who underwent initial hepatic artery reperfusion and 14 who received simultaneous hepatic artery and portal vein reperfusion. Further subdivision within the RTR group identified 19 patients with early hepatic allograft dysfunction (EAD) and 67 without, allowing for an assessment of the influence of preoperative and intraoperative parameters, as well as perfusion methods, on EAD incidence post-LT. RESULTS: Alanine aminotransferase (ALT) was 329 (211 ~ 548) and 176 (98 ~ 282) U/L on the 3rd and 7th day after RTR, respectively, which was significantly lower than 451 (288 ~ 918) and 251 (147 ~ 430) U/L in the IPR group (Z =-1.979, -2.299, P = 0.048, 0.021). Aspartate aminotransferase (AST) on postoperative days 3, 5, and 7 was 252 (193, 522), 105 (79, 163), and 93 (41, 135) U/L in the RTR group, respectively; it was also significantly lower than 328 (251, 724), 179 (129, 306), and 150 (91, 200)U/L in the IPR group (Z=-2.212, -3.221, -2.979; P = 0.027, 0.001, 0.003). Logistic regression analysis showed that MELD score was an independent risk factor for EAD after LT. CONCLUSION: RTR LT is more favorable for patients' early postoperative liver function recovery. For patients undergoing LT for RTR, preoperative MELD score was an independent risk factor for their postoperative development of EAD.

Dexmedetomidine Attenuates Inflammation in Elderly Patients Following Major Hepatobiliary and Pancreatic Surgery: A Randomized Clinical Trial.

Background: Dexmedetomidine (Dex) may have anti-inflammatory properties and potentially reduce the incidence of postoperative organ injury. Objective: To investigate whether Dex protects pulmonary and renal function via its anti-inflammatory effects in elderly patients undergoing prolonged major hepatobiliary and pancreatic surgery. Design and Setting: Between October 2019 and December 2020, this randomized controlled trial was carried out at a tertiary hospital in Chongqing, China. Patients: 86 patients aged 60-75 who underwent long-duration (> 4 hrs) hepatobiliary and pancreatic surgery without significant comorbidities were enrolled and randomly assigned into two groups at a 1:1 ratio. Interventions: Patients were given either Dex or an equivalent volume of 0.9% saline (Placebo) with a loading dose of 1 µg kg-1 for 10 min, followed by 0.5 µg kg-1 hr-1 for maintenance until the end of surgery. Main Outcome Measures: The changes in serum concentrations of interleukin-6 (IL-6) and tumour necrosis factor-α (TNF-α) were primary outcomes. Results: At one hour postoperatively, serum IL-6 displayed a nine-fold increase (P<0.05) in the Placebo group. Administration of Dex decreased IL-6 to 278.09 ± 45.43 pg/mL (95% CI: 187.75 to 368.43) compared to the Placebo group (P=0.019; 432.16 ± 45.43 pg/mL, 95% CI: 341.82 to 522.50). However, no significant differences in TNF-α were observed between the two groups. The incidence of postoperative acute kidney injury was twice as high in the Placebo group (9.30%) compared to the Dex group (4.65%), and the incidence of postoperative acute lung injury was 23.26% in the Dex group, lower than that in the Placebo group (30.23%), although there was no statistical significance between the two groups. Conclusion: Dex administration in elderly patients undergoing major hepatobiliary and pancreatic surgery reduces inflammation and potentially protects kidneys and lungs.

Opioid-free anaesthesia with dexmedetomidine and lidocaine versus remifentanil-based anaesthesia in cardiac surgery: study protocol of a French randomised, multicentre and single-blinded OFACS trial.

INTRODUCTION: Intraoperative opioids have been used for decades to reduce negative responses to nociception. However, opioids may have several, and sometimes serious, adverse effects. Cardiac surgery exposes patients to a high risk of postoperative complications, some of which are common to those caused by opioids: acute respiratory failure, postoperative cognitive dysfunction, postoperative ileus (POI) or death. An opioid-free anaesthesia (OFA) strategy, based on the use of dexmedetomidine and lidocaine, may limit these adverse effects, but no randomised trials on this issue have been published in cardiac surgery.We hypothesised that OFA versus opioid-based anaesthesia (OBA) may reduce the incidence of major opioid-related complications after cardiac surgery. METHODS AND ANALYSIS: Multicentre, randomised, parallel and single-blinded clinical trial in four cardiac surgical centres in France, including 268 patients scheduled for coronary artery bypass grafting under cardiac bypass, with or without aortic valve replacement. Patients will be randomised to either a control OBA protocol using remifentanil or an OFA protocol using dexmedetomidine/lidocaine. The primary composite endpoint is the occurrence of at least one of the following: (1) postoperative cognitive disorder evaluated by the Confusion Assessment Method for the Intensive Care Unit test, (2) POI, (3) acute respiratory distress or (4) death within the first 48 postoperative hours. Secondary endpoints are postoperative pain, morphine consumption, nausea-vomiting, shock, acute kidney injury, atrioventricular block, pneumonia and length of hospital stay. ETHICS AND DISSEMINATION: This trial has been approved by an independent ethics committee (Comité de Protection des Personnes Ouest III-Angers on 23 February 2021). Results will be submitted in international journals for peer reviewing. TRIAL REGISTRATION NUMBER: NCT04940689, EudraCT 2020-002126-90.

Risk factors for postoperative urinary retention in fragility hip fracture patients: a prospective study.

BACKGROUND: Postoperative urinary retention (POUR) among older patients with hip fractures is common and may result in delayed ambulation, prolonged hospital stays, and urinary tract infections. Although preoperative urinary catheter indwelling and early postoperative removal can prevent perioperative urinary retention, this condition may occur in some patients after catheter removal, which requires urinary catheter re-indwelling or intermittent catheterization. Therefore, this study aims to identify risk factors and develop a screening tool for postoperative urinary retention in patients who have undergone operative treatment for fragility hip fractures subsequent to urinary catheter removal. METHODS: A prospective cohort study of 145 fragility hip fracture in older patients who were operatively treated between September 2020 and May 2022 was conducted. All patients were evaluated for urine retention after urinary catheter removal using a bladder scan. In addition, factors related to urinary retention were collected and utilized for screening tool development. RESULTS: Of the included patients, 22 (15.2%) were diagnosed with POUR. A multivariable logistic regression model using a stepwise backward elimination algorithm identified the current use of drugs with anticholinergic effect (OR = 11.9, p = 0.012), international prostate symptom score (IPSS) ≥ 8 (OR = 9.3, p < 0.001), and inability to independently get out of bed within 24 h postoperatively (OR = 6.5, p = 0.051) as risk factors of POUR. The screening tool that has been developed revealed an excellent performance (AuROC = 0.85, 95%CI 0.75 to 0.91) with good calibration and minimal optimism. CONCLUSIONS: Current use of drugs with anticholinergic effects, IPSS ≥ 8, and inability to independently get out of bed within 24 h postoperatively are significant variables of POUR. For additional external validation, a proposed scoring system for POUR screening was developed. TRIAL REGISTRATION: The study protocol was retrospectively registered in The Thai Clinical Trials Registry (TCTR20220502001: 2 May 2022).

Robotic partial nephrectomy is associated with a significantly decreased rate of postoperative pseudoaneurysm compared to open and laparoscopic partial nephrectomy.

While partial nephrectomy offers oncologic efficacy and preserves renal function for T1 renal tumors, renal artery pseudoaneurysm (RAP) remains a rare but potentially life-threatening complication. This study compared RAP incidence across robotic-assisted (RAPN), laparoscopic (LPN), and open (OPN) partial nephrectomies in a large tertiary oncological center. This retrospective study analyzed 785 patients undergoing partial nephrectomy between 2012 and 2022 (398 RAPN, 122 LPN, 265 OPN). Data included demographics, tumor size/location, surgical type, clinical presentation, treatment, and post-operative outcomes. The primary outcome was RAP incidence, with secondary outcomes including presentation, treatment efficacy, and renal function. Seventeen patients (2.1%) developed RAP, presenting with massive hematuria (100%), hemorrhagic shock (5.8%), and clot retention (23%). The median onset was 12 days postoperatively. RAP occurred in 4 (1%), 4 (3.3%), and 9 (3.4%) patients following RAPN, LPN, and OPN, respectively (p = 0.04). Only operative length and surgical approach were independently associated with RAP. Selective embolization achieved immediate bleeding control in 94%, with one patient requiring a second embolization. No additional surgery or nephrectomy was needed. Estimated GFR at one year was similar across both groups (p = 0.53). RAPN demonstrated a significantly lower RAP incidence compared to LPN and OPN (p = 0.04). Emergency angiographic embolization proved effective, with no long-term renal function impact. This retrospective study lacked randomization and long-term follow-up. Further research with larger datasets and longer follow-ups is warranted. This study suggests that robotic-assisted partial nephrectomy is associated with a significantly lower risk of RAP compared to traditional approaches. Emergency embolization effectively treats RAP without compromising long-term renal function.

Effect of different anesthetic modalities on postoperative delirium in elderly hip fractures: A meta-analysis.

BACKGROUND: Previous findings on the effect of general versus spinal anesthesia on postoperative delirium in elderly people with hip fractures are somewhat controversial. This article included the latest randomized controlled study for meta-analysis to evaluate the effect of general anesthesia (GA) and spinal anesthesia (SA) on delirium after hip fracture surgery in the elderly, so as to guide the clinical. METHODS: Cochrane Library, PubMed, Web Of Science, and Embase were searched from inception up to January 16, 2024. Randomized controlled trial (RCT) was included to evaluate the postoperative results of GA and SA in elderly patients (≥50 years old) undergoing hip fracture surgery. Two researchers independently screened for inclusion in the study and extracted data. Heterogeneity was assessed by the I²and Chi-square tests, and P < .1 or I² ≥ 50% indicated marked heterogeneity among studies. The Mantel-Haenszel method was used to estimate the combined relative risk ratio (RR) and the corresponding 95% confidence interval (CI) for the binary variables. RESULTS: Nine randomized controlled trials were included. There was no significant difference (RR = 0.93, 95% CI = 0.774-1.111, P > .05) in the incidence of postoperative delirium between the GA group and the SA group. In intraoperative blood transfusion (RR = 1.0, 95% CI = 0.77-1.28, Z = 0.04, P = .971), pulmonary embolism (RR = 0.795, 95% CI = 0.332-1.904, Z = 0.59, P = .606), pneumonia (RR = 1.47, 95% CI = 0.75-2.87, P = .675), myocardial infarction (RR = 0.97, 95% CI = 0.24-3.86, Z = 0.05, P = .961), heart failure (RR = 0.80, 95% CI = 0.26-2.42, Z = 0.40, P = .961), urinary retention (RR = 1.42, 95% CI = 0.77-2.61, Z = 1.11, P = .267) were similar between the 2 anesthetic techniques. CONCLUSION: There is no significant difference in the effect of GA and SA on postoperative delirium in elderly patients with hip fracture, and their effects on postoperative complications are similar.

Pycnogenol® supplementation to relieve symptoms after hemorrhoidectomy.

BACKGROUND: Hemorrhoids are a common problem associated with symptoms, like swelling, local thrombosis and generally with a decreased quality of life, often in otherwise healthy subjects. Hemorrhoids can be classified by grades (I to IV) according to their severity. In this registry study subjects treated with excisional hemorrhoidectomy (EH) for the first time, were included. After surgery, edema tends to complicate surgical areas causing relevant symptoms. Most hemorrhoids symptoms are related to alterations in bowel habits. Increase in diet fibers to avoid constipation, exercise, and limiting straining reduce recurrence after surgery. METHODS: The aim of the registry study was to evaluate the effects of Pycnogenol® (Horphag Research, Geneva, Switzerland) on relieving postoperative symptoms following hemorrhoidectomy. Pycnogenol® 150 mg/day was used between one month before surgery up to one month after surgery. The main postoperative symptoms were scored. RESULTS: Thirty-eight subjects completed the 60-day supplement registry study. Eighteen subjects were supplemented with Pycnogenol® in addition to the standard management (SM) and 20 subjects only received SM and were considered as controls. The two groups were comparable for age, sex and main symptoms distribution and for their clinical characteristics at inclusion. No other disease was present. The scores for pain, discomfort, and constipation were significantly lower with the supplement compared to controls (P<0.05) 10 and 30 days after surgery. In addition, the quality-of-life score was higher with Pycnogenol® (P<0.05) while bleeding (minimal, not clinically evaluable) and a possible residual anal stenosis (requiring a longer period of observation) were barely observed. A satisfactory return to activity was observed 30 days after surgery in the 18 subjects using Pycnogenol®, and in only 15 out of 20 patients (75%) in the control group (P<0.05). All Pycnogenol® subjects were able to drive and perform daily tasks in comparison with 14 out of 20 subjects in the control group. The proportion of patients that took pain medication from day 10 to 30 post-surgery was significantly lower in the Pycnogenol® group than in controls (P<0.05). CONCLUSIONS: In this post-surgical pilot, registry study, Pycnogenol® was effective in preventing and controlling postoperative symptoms after hemorrhoidectomy. To confirm the results, more cases are needed, including different surgical methods and clinical conditions. Mucosal and cutaneous edema and perianal swelling - generally seen after surgery - seem to be clearly reduced with Pycnogenol® and the supplement intake was associated with a more regular and pain-controlled convalescence and healing.
