OBJECTIVES: To observe the effect of transcutaneous electrical acupoint stimulation (TEAS) on postoperative urinary function in elderly patients undergoing total hip arthroplasty (THA). METHODS: One hundred and eighty elderly patients undergoing unilateral THA without indwelling urinary catheters were randomly assigned to a TEAS group (90 cases, 3 cases dropped out, 4 cases were eliminated) and a sham TEAS group (90 cases, 1 case dropped out, 4 cases were eliminated). Both groups received fascia iliac block and subarachnoid block anesthesia under ultrasound guidance. The patients in the TEAS group were treated with TEAS at Zhongji (CV 3), Guanyuan (CV 4), and bilateral Huiyang (BL 35), Ciliao (BL 32) 30 minutes before anesthesia initiation, with dissperse-dense wave, frequency of 2 Hz/100 Hz, until 30 minutes after surgery. The patients in the sham TEAS group underwent the same procedure with the device applied at the same acupoints but without electrical stimulation. The incidence of postoperative urinary retention (POUR), time to first void, voiding threshold, urinary adenosine triphosphate (ATP) level, postoperative abnormal voiding status (bladder residual volume, re-catheterization rate, nocturia occurrence), and postoperative incidence of urinary tract infection (UTI) and prosthetic joint infection (PJI) were observed in both groups. RESULTS: The incidence of POUR in the TEAS group was lower than that in the sham TEAS group (P<0.05); the time to first void in the TEAS group was shorter than that in the sham TEAS group (P<0.05); the voiding threshold in the TEAS group was lower than that in the sham TEAS group (P<0.05); the urinary ATP level in the TEAS group was higher than that in the sham TEAS group (P<0.05); the bladder residual volume in the TEAS group was lower than that in the sham TEAS group (P<0.05); the nocturia occurrence in the TEAS group was lower than that in the sham TEAS group (P<0.05). However, there was no statistically significant difference in re-catheterization rate, incidence of UTI, and incidence of PJI between the two groups (P>0.05). CONCLUSIONS: TEAS could effectively reduce the occurrence of postoperative urinary retention and improve the postoperative urinary function in elderly patients undergoing THA, which might be related with increasing the urinary ATP level.

[Phytoprophylaxis of complications after extracorporeal lithotrips].

AIM: To evaluate the efficiency of the drug phytolysin (capsules) in the prevention of complications after extracorporeal lithotripsy. MATERIALS AND METHODS: A total of 15 patients diagnosed with urolithiasis and chronic pyelonephritis in the latent phase were treated. The predominant localization of radiopaque stones no larger than 20 mm in size was the collecting system. The piezoelectric lithotripsy (1-2 sessions) was performed, followed by the administration of the herbal drug Phytolysin in the dosage form of a capsule. The follow-up was carried out after 14- and 30-days using laboratory, ultrasound and x-ray methods. RESULTS: In the postoperative period, there were no cases of the pyelonephritis, which may result from a short-term disturbance of the upper urinary tract urodynamics due to the passage of stone fragments. The antibacterial, antispasmodic, diuretic and anti-inflammatory effects of Phytolysin ensured positive changes in laboratory and bacteriological tests, contributed to the prevention of postoperative complications after extracorporeal lithotripsy (renal colic, pyelonephritis), and contributed to maintaining renal blood flow within normal limits and significantly reduced the time to stone-free status. CONCLUSIONS: Our results justify the feasibility of using phytolysin in capsules in patients with urolithiasis after extracorporeal lithotripsy. The dosage form in capsules eliminates the undesirable effects associated with the specific smell and taste, that patients noted when using phytolysin in the form of a paste.

Prediction models for postoperative recurrence of non-lactating mastitis based on machine learning.

OBJECTIVES: This study aims to build a machine learning (ML) model to predict the recurrence probability for postoperative non-lactating mastitis (NLM) by Random Forest (RF) and XGBoost algorithms. It can provide the ability to identify the risk of NLM recurrence and guidance in clinical treatment plan. METHODS: This study was conducted on inpatients who were admitted to the Mammary Department of Shuguang Hospital affiliated to Shanghai University of Traditional Chinese Medicine between July 2019 to December 2021. Inpatient data follow-up has been completed until December 2022. Ten features were selected in this study to build the ML model: age, body mass index (BMI), number of abortions, presence of inverted nipples, extent of breast mass, white blood cell count (WBC), neutrophil to lymphocyte ratio (NLR), albumin-globulin ratio (AGR) and triglyceride (TG) and presence of intraoperative discharge. We used two ML approaches (RF and XGBoost) to build models and predict the NLM recurrence risk of female patients. Totally 258 patients were randomly divided into a training set and a test set according to a 75%-25% proportion. The model performance was evaluated based on Accuracy, Precision, Recall, F1-score and AUC. The Shapley Additive Explanations (SHAP) method was used to interpret the model. RESULTS: There were 48 (18.6%) NLM patients who experienced recurrence during the follow-up period. Ten features were selected in this study to build the ML model. For the RF model, BMI is the most important influence factor and for the XGBoost model is intraoperative discharge. The results of tenfold cross-validation suggest that both the RF model and the XGBoost model have good predictive performance, but the XGBoost model has a better performance than the RF model in our study. The trends of SHAP values of all features in our models are consistent with the trends of these features' clinical presentation. The inclusion of these ten features in the model is necessary to build practical prediction models for recurrence. CONCLUSIONS: The results of tenfold cross-validation and SHAP values suggest that the models have predictive ability. The trend of SHAP value provides auxiliary validation in our models and makes it have more clinical significance.

Effect of Enoxaparin and Daikenchuto Coadministration on Hepatic Disorder Markers in Gynecological Cancer Patients after Abdominal Surgery.

Enoxaparin and daikenchuto are commonly administered to prevent venous thromboembolism and intestinal obstruction after gynecological malignancy surgery. However, the effects of their combined use on hepatic function are not well studied. This study aimed to clarify the effects of the coadministration of enoxaparin and daikenchuto on hepatic function. First, Japanese Adverse Drug Event Report (JADER) data were analyzed to identify signals of hepatic disorders. Second, a retrospective observational study of patients who underwent surgery for gynecological malignancies was conducted. This study defined hepatic disorders as an increase in aspartate aminotransferase (AST) or alanine aminotransaminase (ALT) levels above the reference values, using 1-h postoperative values as the baseline. The analysis of JADER data revealed an increased risk for hepatic disorders with the coadministration of enoxaparin and daikenchuto. An observational study also showed higher odds ratios (95% confidence intervals) for the occurrence of hepatic disorders in the coadministration group (4.27; 2.11-8.64) and enoxaparin alone group (2.48; 1.31-4.69) than in the daikenchuto alone group. The median increase in the ALT level was also higher in the coadministration group (34; 15-59) than in the enoxaparin alone (19; 6-38) and daikenchuto alone groups (8; 3-33). In conclusion, our study suggests that compared with the use of enoxaparin or daikenchuto alone, enoxaparin and daikenchuto coadministration increases the risk of hepatic disorders, with more significant increases in AST and ALT levels. Healthcare workers need to be aware of these potential side effects when combining these drugs after surgery for gynecological malignancies.

Efficacy of selenium on patients undergoing cardiac surgery: a meta-analysis of randomized controlled trials.

INTRODUCTION: Postoperative complications pose significant challenges in cardiac surgery and with the evolution of selenium as a potential anti-inflammatory agent, some studies reported its inefficiency. Thus, we conducted our meta-analysis to evaluate the impact of selenium supplementation on cardiac surgery patients. METHODS: Different databases such as PubMed, Embase, and Cochrane Library from inception till January 2024 were searched identifying a total of seven randomized-controlled trials involving selenium supplementation after cardiac surgery. Risk ratio (RR) and Mean difference (MD) were calculated with a 95% confidence interval (CI). RESULTS: The selenium intervention significantly raised the incidence of Acute Kidney injury (RR 0.76; 95% CI: 0.59, 0.98; P = 0.04) while significantly reducing the duration of hospital stay (MD -1.33; 95% CI: -2.51, -0.16; P = 0.03) and postoperative CRP levels (SMD -0.18; 95% CI: -0.34, -0.02; P = 0.03). The effect of selenium intervention on days spent in ICU (MD -0.01; 95% CI: -0.28, 0.25; P = 0.92), mortality (RR 1.07; 95% CI: 0.84, 1.37; P = 0.57) and incidence of hospital acquired infections (RR 0.98; 95% CI: 0.76, 1.26; P = 0.88) is insignificant. CONCLUSION: Selenium supplementation did not significantly reduce major postoperative complications in cardiac surgery patients. However, its ability to modulate inflammation, as reflected in decreased C-reactive protein levels, highlights its potential role in managing the inflammatory response. Future investigations should focus on optimized selenium supplementation strategies in conjunction with other antioxidants to enhance its benefits.

Multimodality Imaging of Postmastectomy Breast Reconstruction Techniques, Complications, and Tumor Recurrence.

For women undergoing mastectomy, breast reconstruction can be performed by using implants or autologous tissue flaps. Mastectomy options include skin- and nipple-sparing techniques. Implant-based reconstruction can be performed with saline or silicone implants. Various autologous pedicled or free tissue flap reconstruction methods based on different tissue donor sites are available. The aesthetic outcomes of implant- and flap-based reconstructions can be improved with oncoplastic surgery, including autologous fat graft placement and nipple-areolar complex reconstruction. The authors provide an update on recent advances in implant reconstruction techniques and contemporary expanded options for autologous tissue flap reconstruction as it relates to imaging modalities. As breast cancer screening is not routinely performed in this clinical setting, tumor recurrence after mastectomy and reconstruction is often detected by palpation at physical examination. Most local recurrences occur within the skin and subcutaneous tissue. Diagnostic breast imaging continues to have a critical role in confirmation of disease recurrence. Knowledge of the spectrum of benign and abnormal imaging appearances in the reconstructed breast is important for postoperative evaluation of patients, including recognition of early and late postsurgical complications and breast cancer recurrence. The authors provide an overview of multimodality imaging of the postmastectomy reconstructed breast, as well as an update on screening guidelines and recommendations for this unique patient population. ©RSNA, 2024 Test Your Knowledge questions for this article are available in the supplemental material.

The role of traditional Chinese medicine in postoperative wound complications of gastric cancer.

Due to the high risks of postoperative complications brought on by gastric cancer, traditional Chinese medicine (TCM) as a commonly used therapy, has exerted its vital role in postoperative recovery care. In this sense, this meta-analysis was conducted to explore the related documents about TCM's impact on gastric cancer postoperative recovery. During the research, we explored a total of 1549 results from databases PubMed, China National Knowledge Infrastructure (CNKI), Embase, Cochrane Library and Web of Science (WoS). Thirty-two clinical randomized trials (RCTs) were then selected and analysed for this meta-analysis by using the software RevMan 5.4 (under PRISMA 2020 regulations), with a population of 3178 patients. Data prove that TCM therapy reduced the risks for postoperative complications exposure by an estimated average of 19% (95% CI). Among the complications, TCM therapy suppressed the risks of wound infection and incisional infections by 53% and 48% respectively. Meanwhile, the patient's wound healing duration exhibited a significant reduction compared to those without TCM treatment, with a difference at around 0.74 days (95% CI). TCM also exerted its potential to strengthen the patient's immune and health conditions, leading to a significantly promoted gastrointestinal function in the patients with a shorter duration to release first exhaustion and defecation compared to those with no TCM therapy. In addition, similar promoted phenomena also exist in those patients with TCM therapy in terms of their immunity and nutritional conditions. These facts all indicate a positive impact of TCM therapy in clinical applications.

[A prospective comparative study on effectiveness of single versus continuous adductor canal block combined with local infiltration anesthesia in unicompartmental knee arthroplasty].

Objective: To compare the early analgesic effects and the impact on knee joint function recovery after unicompartmental knee arthroplasty (UKA) between single adductor canal block (SACB) and continuous adductor canal block (CACB) combined with local infiltration anesthesia (LIA) using a prospective study. Methods: The patients with knee osteoarthritis admitted between April 2022 and December 2023 were enrolled as a subject. Among them, 60 patients met the selection criteria and were enrolled in the study. They were randomly assigned to the SACB group or CACB group in a ratio of 1:1 using a random number table method. There was no significant difference between the two groups ( P>0.05) in terms of age, gender, height, body mass, body mass index, affected side, and preoperative resting visual analogue scale (VAS) score and active VAS score, Oxford knee score (OKS), and American Hospital of Special Surgery (HSS) score. All patients received multimodal analgesia management using LIA combined with SACB or CACB. The operation time, pain related indicators (resting and activity VAS scores, number and timing of breakthrough pain, opioid consumption), joint function related indicators (quadriceps muscle strength, knee range of motion, OKS score, and HSS score), as well as postoperative block complications and adverse events were recorded and compared between the two groups. Results: There was no significant difference in the operation time between the two groups ( P<0.05). All patients in the two groups were followed up with a follow-up time of (9.70±4.93) months in the SACB group and (12.23±5.05) months in the CACB group, and the difference was not significant ( P>0.05). The CACB group had a significant lower resting VAS score at 24 hours after operation compared to the SACB group ( P<0.05). There was no significant difference in resting and active VAS scores between the two groups at other time points ( P>0.05). The CACB group had a significantly lower incidence of breakthrough pain compared to the SACB group [9 cases (30.00%) vs. 17 cases (56.67%); P<0.05). However, there was no significant difference in the timing of breakthrough pain occurrence and opioid consumption between the two groups ( P>0.05). Four cases in the SACB group and 7 cases in the CACB group experienced adverse events, with no significant difference in the incidence of adverse events between the two groups ( P>0.05). The CACB group had significantly better knee joint mobility than the SACB group at 1 and 2 days after operation ( P<0.05). There was no significant difference between the two groups in knee joint mobility on 0 day after operation and quadriceps muscle strength and OKS and HSS scores at different time points ( P>0.05). Conclusion: In UKA, the analgesic effects and knee joint function recovery are similar when compared between LIA combined with SACB and LIA combined with CACB. However, SACB is simpler to perform and can avoid adverse events such as catheter displacement and dislocation. Therefore, SACB may be a better choice.

Transurethral bipolar enucleation using a TUEB loop for large benign prostatic hyperplasia: a retrospective cohort study.

PURPOSE: We aimed to assess the efficacy and safety of transurethral enucleation with bipolar system (TUEB) regardless of the prostate size using a specially developed TUEB loop. METHODS: A total of 251 patients who underwent TUEB were categorized into two groups depending on the prostate volume (PV): small-PV (≤ 80 mL) group, 133 patients; large-PV (> 80 mL) group, 118 patients. Comparisons of background information and treatment outcomes were performed between the groups. RESULTS: Operation (113.5 vs 166.4 min), enucleation (49.4 vs 68.1 min), and morcellation (11.4 vs 26.4 min) times were longer and hemoglobin decreased significantly (0.84 vs 1.30 g/dL) in the large PV group. However, the enucleation efficiency (enucleated weight per enucleation time; 0.71 vs 0.97 g/min) and prostate-specific antigen reduction rate (24.6% vs 16.1%) were significantly better in the large-PV group, with similar enucleation rates (enucleated weight per transitional zone volume; 82% vs 81%). The International Prostate Symptom Score, uroflowmetry maximum flow rate, and post-void residual urine in both groups improved at 3, 6, and 12 months compared with baseline. No patient underwent blood transfusion. There were no differences in the frequency of postoperative clot retention, urethral stricture, or stress incontinence at 3, 6, and 12 months. CONCLUSION: TUEB using a TUEB loop resulted in high levels of satisfaction regarding the enucleation efficiency, efficacy, and safety for BPH surgery regardless of the prostate size. TUEB should be considered one of the best treatment options for large BPH that is uncontrollable with medication.

Electroacupuncture alleviates intestinal inflammation via a distinct neuro-immune signal pathway in the treatment of postoperative ileus.

BACKGROUND: The induction of intestinal inflammation as a result of abdominal surgery is an essential factor in postoperative ileus (POI) development. Electroacupuncture (EA) at ST36 has been demonstrated to relieve intestinal inflammation and restore gastrointestinal dysmotility in POI. This study aims to elucidate the neuroimmune pathway involved in the anti-inflammatory properties of EA in POI. METHODS: After intestinal manipulation (IM) was performed to induce POI, intestinal inflammation and motility were assessed 24 h post-IM, by evaluating gastrointestinal transit (GIT), cytokines expression, and leukocyte infiltration. Experimental surgery, pharmacological intervention, and genetic knockout mice were used to elucidate the neuroimmune mechanisms of EA. RESULTS: EA at ST36 significantly improved GIT and reduced the expression of pro-inflammatory cytokines and leukocyte infiltration in the intestinal muscularis following IM in mice. The anti-inflammatory effectiveness of EA treatment was abolished by sub-diaphragmatic vagotomy, whereas splenectomy did not hinder the anti-inflammatory benefits of EA treatment. The hexamethonium chloride (HEX) administration contributes to a notable reduction in the EA capacity to suppress inflammation and enhance motility dysfunction, and EA is ineffective in α7 nicotinic acetylcholine receptor (α7nAChR) knockout mice. CONCLUSIONS: EA at ST36 prevents intestinal inflammation and dysmotility through a neural circuit that requires vagal innervation but is independent of the spleen. Further findings revealed that the process involves enteric neurons mediating the vagal signal and requires the presence of α7nAChR. These findings suggest that utilizing EA at ST36 may represent a possible therapeutic approach for POI and other immune-related gastrointestinal diseases.

The Influence of High-Dose Parenteral Vitamin C on the Incidence and Severity of Postoperative Pulmonary Complications in Cardiac Surgery with Extracorporeal Circulation: A Randomized Controlled Trial.

Cardiac surgery (CS) with extracorporeal circulation (ECC), induces intense oxidative stress (OS) and systemic inflammatory response (SIR), which may seriously affect postoperative lung function. We aimed to test if high parenteral (200 mg/kg/24 h) daily doses of Vitamin C (VitC), given within 48 h after the beginning of the operation, may reduce the incidence and severity of postoperative pulmonary complications (PPCs) in CS patients. This single-center, prospective, randomized, single-blinded, interventional trial included 150 patients, assigned to control Group A (n = 75) and interventional Group B (n = 75). Group B intraoperatively received one-fourth (i.e., 50 mg/kg) of the planned daily Vit C dose, divided into three equal parts and diluted in 10 mL of normal saline, while Group A received an equal volume of normal saline at the same time frames (i.e., the induction of anesthesia, aortic cross-clamp release, and sternal closure). After 6 h from the first intraoperative dose, the following regimen was applied: Group B: 50 mg/kg, 30 min i.v. infusion of VitC in 50 mL of normal saline, every 6 h, for the next 48 h, and Group A: 30 min i.v. infusion of an equal volume of normal saline every 6 h, for the next 48 h. Modified Kroenke's score was used to determine the incidence and severity of PPCs. The overall incidence of PPCs was 36.7% and was significantly lower in Group B (13.3% vs. 60.0%, p < 0.001). The PPCs severity score was also significantly lower in Group B (1 vs. 3, p < 0.001). In addition, patients from Group B had significantly less damaged lungs, better postoperative renal function, shorter ICU stays, fewer ICU re-admissions, and lower hospital mortality. No VitC-related adverse effects were recorded. High parenteral daily VitC doses given within 48 h after the beginning of CS are safe and effective in reducing the incidence and severity of PPCs. A multicenter RCT is needed to confirm these results.

Exploring the Efficacy of the Paula Method of Muscle Exercises in Managing Low Anterior Resection Syndrome Using an Integrative Approach: A Preliminary Study.

Background: Low anterior resection syndrome (LARS) is a post-proctectomy consequence characterized by variable and unpredictable bowel function, including clustering, urgency, and incontinence, which significantly impacts the quality of life. Currently, there is no established gold-standard therapy for LARS. Primary Study Objective: This study aimed to evaluate the effectiveness of the Paula method of exercise as part of an integrative treatment approach for patients with LARS. Design: This preliminary study utilized a single-arm pretest-posttest design. Setting: The study was conducted at a tertiary care medical center. Participants: Five patients diagnosed with LARS completed the study. Intervention: Participants underwent twelve weeks of individualized Paula method exercise sessions. Two questionnaires were employed to assess the severity of LARS and quality of life. Primary Outcome Measures: (1) Low Anterior Resection Syndrome (LARS) Score; (2) Memorial Sloan Kettering Cancer Bowel Function Instrument (MSK-BFI); (3) Global Quality-of-Life (QOLS) Score . Results: All participants completing the 12-week Paula exercise regimen reported no difficulty in engaging with the exercises. Statistically significant improvements were observed in both the LARS score and MSK-BFI (P = .039 and P = .043, respectively, Wilcoxon Rank Sum test). While there were improvements in the global quality-of-life score and functional scales of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire, these improvements did not reach statistical significance. Conclusions: This preliminary study suggests that patients with LARS can successfully complete a 12-week exercise program using the Paula method, resulting in improved LARS scores. However, further investigation through larger, multicenter, randomized controlled trials is necessary to establish the efficacy of these exercises as a treatment for LARS.

Preoperative serum selenium predicts acute kidney injury after adult cardiac surgery.

BACKGROUND: The relationship between serum selenium (Se) and acute kidney injury after adult cardiac surgery (CSA-AKI) remains controversial. This study aimed to investigate the association of preoperative Se level with incident CSA-AKI. METHOD AND RESULTS: A retrospective cohort study was conducted on patients who underwent cardiac surgery. The primary outcome was incident CSA-AKI. Multivariable logistic regression models and natural cubic splines were used to estimate the association of Se levels and primary outcome. A total of 453 patient with a mean age of 62.97 years were included. Among all patients, 159 (35.1%) incident cases of CSA-AKI were identified. The level of preoperative Se concentration in patients with CSA-AKI was significant lower than that in patients without CSA-AKI. The higher preoperative Se level was significantly associated with decreased risk of CSA-AKI (adjusted OR 0.91, 95% CI: 0.87-0.99). Dose-response relationship curve revealed a nearly L-shape correlation between serum Se selenium levels and incident CSA-AKI. CONCLUSION: Our study suggested that a higher level of serum Se was significantly associated with lower risk of CSA-AKI. Further prospective studies are needed to clarify the causal relationship between serum Se level and incident CSA-AKI.

The application of autofluorescence system contributes to the preservation of parathyroid function during thyroid surgery.

PURPOSE: The purpose of this study was to investigate the impact of autofluorescence technology on postoperative parathyroid function and short-term outcomes in patients undergoing thyroid surgery. METHODS: A total of 546 patients were included in the study, with 287 in the conventional treatment group and 259 in the autofluorescence group. Both groups underwent central lymph node dissection, which is known to affect parathyroid function. Short-term outcomes, including rates of postoperative hypocalcemia and parathyroid dysfunction, serum calcium and PTH levels on the first postoperative day, as well as the need for calcium supplementation, were analyzed. A multivariable analysis was also conducted to assess the impact of autofluorescence on postoperative parathyroid dysfunction, considering factors such as age, BMI, and preoperative calcium levels. RESULTS: The autofluorescence group demonstrated significantly lower rates of postoperative hypocalcemia and parathyroid dysfunction compared to the conventional treatment group. The autofluorescence group also had better serum calcium and PTH levels on the first postoperative day, and a reduced need for calcium supplementation. Surprisingly, the use of autofluorescence technology did not prolong surgical time; instead, it led to a shorter hospitalization duration. The multivariable analysis showed that autofluorescence significantly reduced the risk of postoperative parathyroid dysfunction, while factors such as age, BMI, and preoperative calcium levels did not show a significant correlation. CONCLUSION: This study provides evidence that autofluorescence technology can improve the preservation of parathyroid function during thyroid surgery, leading to better short-term outcomes and reduced postoperative complications. The findings highlight the potential of autofluorescence as a valuable tool in the management of parathyroid hypofunction. Further research and validation are needed to establish the routine use of autofluorescence technology in the thyroid.

Clinical outcome and safety of holmium laser prostate enucleation after transrectal prostate biopsies for benign prostatic hyperplasia.

PURPOSE: This study aimed to assess the clinical outcome and safety of holmium laser enucleation of the prostate (HoLEP) following transrectal ultrasound-guided prostate biopsy (TR biopsy) in the treatment of benign prostate hyperplasia. MATERIALS AND METHODS: We retrospectively analyzed data from 556 patients who underwent HoLEP between 2014 and 2021. The patients were categorized into six groups: Group 1-A (n=45) underwent HoLEP within four months post TR biopsy. Group 1-B (n=94) underwent HoLEP more than four months post TR biopsy. Group 1-C (n=120) underwent HoLEP after a single TR biopsy. Group 1-D (n=19) underwent HoLEP after two or more TR biopsies. Group 1-total (n=139, group 1-A+group 1-B or group 1-C+group 1-D) underwent HoLEP post TR biopsy. Group 2 (control group, n=417) underwent HoLEP without prior TR biopsy. We examined perioperative parameters, safety, and functional outcomes. RESULTS: The age, body mass index, International Prostate Symptom Score (IPSS), uroflowmetry, and comorbid diseases between group 1-total and group 2 were comparable. However, group 1-total exhibited significantly elevated prostate-specific antigen levels and larger prostate volumes (p<0.01). Perioperative factors like enucleation time, enucleation weight, and catheterization duration were notably higher in group 1-total (p<0.01). All groups showed significant improvements in IPSS, postvoid residual urine, and maximum flow rate during the 1-year postoperative period (p<0.05). The rates of postoperative complications were similar between group 1-total and group 2. CONCLUSIONS: Enucleation time and catheterization duration were significantly longer in the TR biopsy group. However, postoperative complications were not significantly different between TR biopsy and non-TR biopsy groups.

Impact of Perioperative Immunonutrition on Postoperative Outcomes in Patients with Upper Gastrointestinal Cancer: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

There is no consensus on the efficacy of perioperative immunonutrition in patients with upper gastrointestinal (GI) cancer surgery. We clarified the impact of perioperative immunonutrition on postoperative outcomes in patients with upper GI cancers. We searched MEDLINE (PubMed), MEDLINE (OVID), EMBASE, Cochrane Central Register of Controlled Trials, Web of Science Core Selection, and Emcare from 1981-2022 using search terms related to immunonutrition and upper GI cancer. We included randomized controlled trials. Intervention was defined as immunonutritional therapy, including arginine, n-3 omega fatty acids, or glutamine during the perioperative period. The control was defined as standard nutritional therapy. The primary outcomes were infectious complications, defined as events with a Clavien-Dindo classification grade ≥ II that occurred within 30 days after surgery. After screening, 23 studies were included in the qualitative synthesis and in the quantitative synthesis. The meta-analysis showed that immunonutrition reduced infectious complications (relative risk ratio: 0.72; 95% confidence interval: 0.57-0.92; certainty of evidence: Moderate) compared with standard nutritional therapy. In conclusion, nutritional intervention with perioperative immunonutrition in patients with upper GI cancers significantly reduced infectious complications. The effect of immunonutrition for upper GI cancers in reducing the risk of infectious complications was about 30%.

Multimodal prehabilitation in elective oncological colorectal surgery enhances preoperative physical fitness: a single center prospective real-world data analysis.

BACKGROUND: Surgery can lead to curation in colorectal cancer (CRC) but is associated with significant morbidity. Prehabilitation plays an important role in increasing preoperative physical fitness to reduce morbidity risk; however, data from real-world practice is scarce. This study aimed to evaluate the change in preoperative physical fitness and to evaluate which patients benefit most from prehabilitation. MATERIALS AND METHODS: In this single-arm prospective cohort study, consecutive patients undergoing elective colorectal oncological surgery were offered a 3- to 4-week multimodal prehabilitation program (supervised physical exercise training, dietary consultation, protein and vitamin supplementation, smoking cessation, and psychological support). The primary outcome was the change in preoperative aerobic fitness (steep ramp test (SRT)). Secondary outcomes were the change in functional walking capacity (6-minute walk test (6MWT)), and muscle strength (one-repetition maximum (1RM) for various muscle groups). To evaluate who benefit most from prehabilitation, participants were divided in quartiles (Q1, Q2, Q3, and Q4) based on baseline performance. RESULTS: In total, 101 patients participated (51.4% male, aged 69.7 ± 12.7 years). The preoperative change in SRT was +28.3 W, +0.36 W/kg, +16.7% (P<0.001). Patients in all quartiles improved at the group level; however, the relative improvement decreased from Q1-Q2, Q2-Q3, and Q3-Q4 (P=0.049). Change in 6MWT was +37.5 m, +7.7% (P<0.001) and 1RM improved with 5.6-33.2 kg, 16.1-32.5% for the various muscle groups (P<0.001). CONCLUSION: Prehabilitation in elective oncological colorectal surgery is associated with enhanced preoperative physical fitness regardless of baseline performance. Improvements were relatively larger in less fit patients.

Abdominal massage to prevent ileus after colorectal surgery. A single-center, prospective, randomized clinical trial: the MATRAC Trial.

BACKGROUND: There is scarce literature on the effect of mechanical abdominal massage on the duration of ileus after colectomy, particularly in the era of enhanced recovery after surgery (ERAS). The aim of this study was to determine whether abdominal massage after colorectal surgery with anastomosis and no stoma helps toward a faster return of intestinal transit. METHODS: This study was a superiority trial and designed as a prospective open-label, single-center, randomized controlled clinical trial with two parallel groups. Patients scheduled to undergo intestinal resection and follow an ERAS protocol were randomly assigned to either the standard ERAS group or the ERAS plus massage group. The primary endpoint was the return of intestinal transit, defined as the first passage of flatus following the operation. Secondary endpoints included time of the first bowel motion, maximal pain, 30 day complications, complications due to massage, anxiety score given by the Hospital Anxiety and Depression (HAD) questionnaire, and quality of life assessed by the EQ-5D-3L questionnaire. RESULTS: Between July 2020 and June 2021, 36 patients were randomly assigned to the ERAS group or the ERAS plus massage group (n = 19). Patients characteristics were comparable. There was no significant difference in time to passage of the first flatus between the ERAS group and the ERAS plus abdominal massage group (1065 versus 1389 min, p = 0.274). No statistically significant intergroup difference was noted for the secondary endpoints. CONCLUSION: Our study, despite its limitations, failed to demonstrate any advantage of abdominal massage to prevent or even reduce symptoms of postoperative ileus after colorectal surgery.

Treatment of the infected sacral nerve stimulator: A scoping review.

BACKGROUND: Sacral nerve stimulators (SNSs) are a widely accepted, efficacious surgical option to treat patients who have failed conservative management for overactive bladder, nonobstructive urinary retention, fecal incontinence, or pelvic pain. As with all implanted devices, there are associated risks for surgical site and implant infections. There are currently no clear published data or guidelines regarding treating such infections. AIMS: We present a scoping review aiming to examine the existing literature on the treatment approaches of infected SNSs. METHODS: A scoping review was conducted using Preferred Reporting Items for Systematic Review and Meta-Analysis. The search strategy focused on "sacral modulation," and "infection," and "explantation," and conservative management methods such as "antibiotics." A search was conducted on medical databases, and a grey literature search was performed. RESULTS: Thirty articles were included for data extraction. Articles were published between 2006 and 2022. Outcomes were reported for 7446 patients. Two hundred and seventy-four infection events were reported, giving an overall 3.7% infection rate. Most infection events were treated with explantation, although there is some discussion on the role of conservative management using oral and intravenous antibiotics in the literature. Articles also discussed considerations for future reimplantation after explantation of SNS. CONCLUSIONS: There are currently no treatment protocols in the literature to help guide whether a patient is suited to conservative or surgical management. There is future scope for developing treatment algorithms to guide clinicians for optimal treatment of infected sacral neuromodulation devices.

Outcome Heterogeneity in Prehabilitation Trials-Are We Comparing Apples and Oranges?

INTRODUCTION: Over the last decade, the number of prehabilitation randomised controlled trials (RCTs) has increased significantly. Therefore, this review aimed to describe the outcomes reported in prehabilitation RCTs in patients undergoing cancer surgery. METHODS: A search was conducted in Embase, Allied and Complementary Medicine Database, The Cochrane Library, PsycINFO, MEDLINE, and Cumulated Index to Nursing and Allied Health Literature from inception to July 2021. We included RCTs evaluating the effectiveness of preoperative exercise, nutrition, and psychological interventions on postoperative complications and length of hospital stay in adult oncology patients who underwent thoracic and gastrointestinal cancer surgery. The verbatim outcomes reported in each article were extracted, and each outcome was assessed to determine whether it was defined and measured using a validated tool. Verbatim outcomes were grouped into standardized outcomes and categorized into domains. The quality of outcome reporting in each identified article was assessed using the Harman tool (score range 0-6, where 0 indicated the poorest quality). RESULTS: A total of 74 RCTs were included, from which 601 verbatim outcomes were extracted. Only 110 (18.3%) of the verbatim outcomes were defined and 270 (44.9%) were labeled as either "primary" or "secondary" outcomes. Verbatim outcomes were categorized into 119 standardized outcomes and assigned into one of five domains (patient-reported outcomes, surgical outcomes, physical/functional outcomes, disease activity, and intervention delivery). Surgical outcomes were the most common outcomes reported (n = 71 trials, 95.9%). The overall quality of the reported outcomes was poor across trials (median score: 2.0 [IQR = 0.00-3.75]). CONCLUSIONS: Prehabilitation RCTs display considerable heterogeneity in outcome reporting, and low outcome reporting quality. The development of standardized core outcome sets may help improve article quality and enhance the clinical utility of prehabilitation following cancer surgery.
