Efficacy of Pancreatic Dissection With a Triple-row Stapler in Laparoscopic Distal Pancreatectomy: A Retrospective Observational Study.

Postoperative pancreatic fistulas (POPFs) occur after 20% to 30% of laparoscopic distal pancreatectomies. This study aimed to evaluate the clinical efficacy of laparoscopic distal pancreatectomy using triple-row staplers in preventing POPFs. Between April 2016 and May 2023, 59 patients underwent complete laparoscopic distal pancreatectomies. There were more females (n=34, 57.6%) than males (n=25, 42.4%). The median age of the patients was 68.9 years. The patients were divided into slow-compression (n=19) and no-compression (n=40) groups and examined for pancreatic leakage. Both groups were examined with respect to age, sex, body mass index (BMI), pancreatic thickness at the pancreatic dissection site, pancreatic texture, diagnosis, operative time, blood loss, presence of POPF, date of drain removal, and length of hospital stay. In addition, risk factors for POPF were examined in a multivariate analysis. Grade B POPFs were found in 9 patients (15.3%). Using univariate analysis, the operative time, blood loss, postoperative pancreatic fluid leakage, day of drain removal, and hospital stay were shorter in the no-compression group than in the slow-compression group. Using multivariate analysis, the absence of POPFs was significantly more frequent in the no-compression group (odds ratio, 5.69; 95% CI, 1.241-26.109; P=0.025). The no-compression pancreatic dissection method was a simple method for reducing POPF incidence. The method of quickly dissecting the pancreas without compression yielded better results than the method of slowly dissecting the pancreas with slow compression. This quick dissection without compression was a simple and safe method that minimized postoperative pancreatic fluid leakage, shortened the operative time and length of hospital stay, and reduced medical costs. Therefore, this method might be a clinically successful option.

Corkscrew Technique for Extraction of Premolars and Molars in Standing Sedated Horses: Cadaveric Study and Clinical Cases

Several tooth extraction techniques are described in equine literature, and oral extraction techniques in standing sedated horses are popular among equine practitioners. The objectives of this study were to develop the corkscrew technique for cheek tooth extraction (CSET) in equine cadaver heads and evaluate this technique in clinical cases. We hypothesized that the CSET could be performed safely to extract cheek teeth in standing sedated horses. First, the CSET was attempted and developed in eight equine cadaver heads. Second, the CSET was performed in clinical cases between 2016 and 2020, and the following information was recorded: diagnosis, affected tooth, procedure duration, intraoperative difficulties, tooth size, postoperative complications, medication, hospitalization time, and 1-year follow-up. Sixteen CSET procedures were performed in eight equine skulls with a 75% success rate. In 24 clinical cases, 25 CSET procedures were attempted to extract 22 superior and 3 inferior cheek teeth. CSET was successful in 76% of procedures. Fractures of the tooth and stripping of screw threads were the major complications that led to the failure of CSET. CSET is a viable and safe technique to extract cheek teeth in standing sedated horses. Longitudinal drilling is a must for this technique to be successful.

Retrospective evaluation of the prevalence and risk factors associated with red blood cell transfusions in cats with urethral obstruction (2009-2019): 575 cases.

To evaluate the prevalence of red blood cell (RBC) transfusions and factors associated with the need for transfusion in cases of feline urethral obstruction (FUO). Secondarily, to compare survival to discharge in cats receiving an RBC transfusion versus those that did not. Retrospective, multi-institutional study from 2009 to 2019. Four university teaching hospitals. Six hundred twenty-two total occurrences of FUO in 575 cats. None. Medical records were retrospectively reviewed for pertinent information. The overall prevalence of severe anemia (PCV<0.20L/L [<20%]) at presentation was 1.0% (6/622). The prevalence of RBC transfusions during hospitalization was 2.1% (13/622). Cats that received an RBC transfusion weighed significantly less than those that did not (4.9 vs 5.8kg; P=0.034) and had a lower PCV at presentation (0.30L/L [30%] vs 0.41L/L [41%]; P<0.001). Hospitalization time (240 vs 72h) and indwelling urinary catheter time (168 vs 48h) were significantly longer in cats receiving a transfusion compared with those that did not (P<0.001). Creatinine concentrations were not significantly associated with transfusion administration, while BUN was higher in cats receiving a transfusion (15.35mmol/L [43mg/dL] vs. 11.78mmol/L [33mg/dL]; P=0.043). Transfusion rates were significantly higher in cats undergoing perineal urethrostomy (5.5%) compared with those that did not undergo surgery (0.97%; P<0.001). The overall survival to discharge rate was 96%. Cats not receiving an RBC transfusion were significantly more likely to survive to discharge than those that did (odds ratio: 14.7, 95% confidence interval: 1.8-37; P<0.001). FUO is rarely associated with severe anemia and the need for RBC transfusions. In this study, cats receiving an RBC transfusion were less likely to survive to discharge; therefore, requiring a blood transfusion may be associated with a worse prognosis. In addition, the need for surgical intervention was associated with a higher prevalence of RBC transfusions.

Suture passer combined with two-hole laparoscopic peritoneal dialysis catheterization in patients undergoing peritoneal dialysis

Background Laparoscopic techniques are being widely applied for peritoneal dialysis (PD) catheter (PDC) placement. The suture passer is a novel fixation tool that aims to reduce catheter migration. We compared the clinical value of the suture passer combined with two-hole laparoscopic PDC placement to open surgical placement by evaluating preoperative and postoperative conditions, as well as the onset of complications in both groups. Methods A retrospective study was conducted including 169 patients who underwent PDC placement surgery from January 2021 to May 2023. Based on the method employed, patients were divided into two groups: the suture passer combined with a two-hole laparoscopy group (SLG) and the open surgical group (SG). Comprehensive patient information, including general data, preoperative and postoperative indicators, peritoneal function after surgery, and the incidence rate of complications, were collected and analyzed. Results The SLG showed a statistically significant decrease in operative time, intraoperative blood loss, and 6-month postoperative drift rate compared to the SG (p < 0.05). No statistically significant differences were observed between the two groups in terms of sex, age, primary disease, hospitalization time, hospitalization costs, preoperative and postoperative examination indicators, peritonitis, and omental wrapping. Conclusions Suture passer combined with two-hole laparoscopic PDC placement, characterized by simplicity and facilitating secure catheter fixation, was deemed safe and effective for patients undergoing PD. It reduces the catheter migration rate and improved surgical comfort. Overall, this technique demonstrates favorable outcomes in clinical practice.

Female Surgeons in Cardiac Surgery: Does the Surgeon's Gender Affect the Outcome of Routine Coronary Artery Bypass Graft and Isolated Aortic Valve Surgery?

The increasing presence of female doctors in the field of cardiac surgery has raised questions about their surgical quality compared to their male colleagues. Despite their success, female surgeons are still underrepresented in leadership positions, and biases and concerns regarding their performance persist. This study aims to examine whether female surgeons perform worse, equally well, or better than their male counterparts in commonly performed procedures that have a significant number of female patients. A retrospective cohort of patients from 2011 to 2020 who underwent isolated coronary artery bypass graft (CABG) and aortic valve surgery was studied. To compare the surgical quality of men and women, a 1:1 propensity score matching (two groups of 680 patients operated by men and women, respectively, factors: age, logarithm of EuroSCORE (ES), elective, urgent or emergent surgery, isolated aortic valve, or isolated CABG) was performed. Procedure time, bypass time, x-clamp time, hospital stay, and early mortality were compared. After propensity score matching between surgeons of both sexes, patients operated by males (PoM) did not differ from patients operated by females (PoF) in mean age (PoM: 66.72 ± 9.33, PoF: 67.24 ± 9.19 years, p = 0.346), log. ES (PoM: 5.58 ± 7.35, PoF: 5.53 ± 7.26, p = 0.507), or urgency of operation (PoM: 43.09% elective, 48.97% urgent, 7.94% emergency, PoF: 40.88% elective, 55.29% urgent, 3.83% emergency, p = 0.556). This was also the case for male and female patients separately. Female surgeons had higher procedure time (PoM: 224.35 ± 110.54 min; PoF: 265.41 ± 53.60 min), bypass time (PoM: 107.46 ± 45.09 min, PoF: 122.42 ± 36.18 min), and x-clamp time (PoM: 61.45 ± 24.77 min; PoF: 72.76 ± 24.43 min). Hospitalization time (PoM: 15.96 ± 8.12, PoF: 15.98 ± 6.91 days, p = 0,172) as well as early mortality (PoM: 2.21%, PoF: 3.09%, p = 0.328) did not differ significantly. This was also the case for male and female patients separately. Our study reveals that in routine heart surgery, the gender of the surgeon does not impact the success of the operation or the early outcome of patients. Despite taking more time to perform procedures, female surgeons demonstrated comparable surgical outcomes to their male counterparts. It is possible that women's inclination for thoroughness contributes to the longer duration of procedures, while male surgeons may prioritize efficiency. Nevertheless, this difference in duration did not translate into significant differences in primary outcomes following routine cardiac surgery. These findings highlight the importance of recognizing the equal competence of female surgeons and dispelling biases regarding their surgical performance.

Should We Operate Nonagenarians with Symptomatic Giant Paraesophageal Hernias?

Introduction: Hiatal hernia (HH) is a common disorder of the upper gastrointestinal (UGI) tract that general surgeons encounter. Giant paraesophageal is a subtype of HH in which more than 30% of the stomach is located in the chest. It can cause symptoms such as dysphagia, UGI bleeding, gastroesophageal reflux disease, and vomiting. As the life expectancy of the general population increases, the incidence of giant HH increases and can cause morbidity, including recurrent admissions and prolonged length of hospitalization. In this article, we describe a cohort of nonagenarian patients with HH who were admitted to our institution and were treated either surgically or medically. Methods: We retrospectively reviewed our prospectively maintained database of all nonagenarians who were admitted to our center between 2018 and 2022 with the diagnosis of HH. We compared the demographic data, clinical data, and outcomes between patients undergoing operative and nonoperative management. Results: Twenty patients of age over 90 years were hospitalized with HH-related symptoms. Six underwent surgery, whereas 14 received medical management. Surgical patients had fewer overall hospitalization days, shorter length of stay, and less blood product requirements. Notably two cases of in-hospital mortality occurred in the nonoperative group, whereas none occurred in the operative group. All surgical procedures were performed laparoscopically, with two minor perioperative complications. Conclusion: In selected nonagenarian patients, laparoscopic HH repair is safe and should be considered favorably. It can reduce hospitalization time and can mitigate morbidity.

Detrimental Impact of Atrial Fibrillation among Patients Hospitalized for Acute Exacerbation of COPD: Results of a Population-Based Study in Spain from 2016 to 2021

Background/Objectives: To analyze changes in the prevalence of atrial fibrillation (AF) in patients hospitalized for acute exacerbation of chronic obstructive pulmonary disease (AE-COPD); to evaluate hospital outcomes according to AF status, assessing sex differences; to identify factors associated with AF presence; and to analyze variables associated with in-hospital mortality (IHM) in AE-COPD patients with AF. Methods: We used data from the Registry of Specialized Care Activity-Basic Minimum Data Set (RAE-CMBD) to select patients aged ≥40 years with COPD in Spain (2016–2021). We stratified the study population according to AF presence and sex. The propensity score matching (PSM) methodology was employed to create comparable groups based on age, admission year, and comorbidities at the time of hospitalization. Results: We identified 399,196 hospitalizations that met the inclusion criteria. Among them, 20.58% had AF. The prevalence of AF rose from 2016 to 2021 (18.26% to 20.95%), though the increase was only significant in men. The median length of hospital stay (LOHS) and IHM were significantly higher in patients with AF than in those without AF. After PSM, IHM remained significantly higher for man and women with AF. Older age, male sex, and several comorbidities were factors associated with AF. Additionally, older age, male sex, different comorbidities including COVID-19, hospitalization in the year 2020, mechanical ventilation, and intensive care unit (ICU) admission were associated with higher IHM in patients with AE-COPD and AF. Conclusions: AF prevalence was high in patients hospitalized for AE-COPD, was higher in men than in women, and increased over time. AF presence was associated with worse outcomes. The variables associated with IHM in hospitalized AE-COPD patients with AF were older age, male sex, different comorbidities including COVID-19 presence, hospitalization in the year 2020, need of mechanical ventilation, and ICU admission.

Features of nutritional support for dysphagia. The role of a speech therapist

Neurogenic oropharyngeal dysphagia remains a widespread complication of neurological diseases. Its prevalence in stroke patients reaches 50%, among patients with multiple sclerosis — 44%, with amyotrophic lateral sclerosis — 60%, after brain injury — 50%, with Parkinson’s disease — 84%. Neurogenic oropharyngeal dysphagia can lead to a decrease in food intake, development of malnutrition and dehydration, and can also be complicated by the development of aspiration pneumonia, followed by death. Currently, the detection of dysphagia in hospitalized patients is often carried out late or outside the algorithm, which significantly increases the risk of nutritional deficiency, decreased quality of life, and other complications when eating. A clinical study of the swallowing function at the earliest possible time of hospitalization avoids delays in diagnosis and timely determines the feeding tactics of a patient with neurogenic dysphagia. The assessment of the swallowing function should be carried out in the first hours of the patient’s hospitalization, and the main conclusion to be drawn from the results of a clinical study of the swallowing function is whether the patient can receive food through the mouth to satisfy nutritional needs. Despite the urgency of the problem of the development of nutritional deficiency in patients with dysphagia, there are few specific recommendations in the Russian literature on the stages of diagnosis, medical rehabilitation and nutritional support for this category of patients. This review is devoted to the analysis of the need for correct diagnosis and rehabilitation of patients with dysphagia and the impact of dysphagia on the quality of life and nutritional status of the patients.

Perioperative, Oncological, and Functional Outcomes Between Robot-Assisted Laparoscopic Prostatectomy and Open Radical Retropubic Prostatectomy: A Randomized Clinical Trial.

Limited high-quality studies have compared robot-assisted laparoscopic prostatectomy (RALP) vs open retropubic radical prostatectomy. We sought to compare their postoperative outcomes in a randomized setting. In a single center, 354 men with newly diagnosed prostate cancer were assessed for eligibility; 342 were randomized (1:1). The primary outcome was 90-day complication rates. Functional outcomes and quality of life were assessed over 18 months, and oncological outcomes, biochemical recurrence-free survival, and additional treatment over 36 months. From 2014 to 18, 327 patients underwent surgery (retropubic radical prostatectomy = 156, RALP = 171). Complications occurred in 27 (17.3%) vs 19 (11.1%; P = .107). Patients undergoing RALP experienced lower median bleeding (250.0 vs 719.5 mL; P < .001) and shorter hospitalization time. Urinary EPIC (Expanded Prostate Cancer Index Composite) median scores were better for RALP over 18 months, with higher continence rate at 3 months (80.5% vs 64.7%; P = .002), 6 months (90.1% vs 81.6%; P = .036) and 18 months (95.4% vs 78.8%; P < .001). Sexual EPIC and Sexual Health Inventory for Men median scores were higher with RALP up to 12 months, while the potency rate was superior at 3 months (23.9% vs 5.3%; P = .001) and 6 months (30.6% vs 6.9%; P < .001). Quality of life over the 18 months and oncological outcomes over 36 months were not significantly different between arms. Complications at 90 days were similar. RALP showed superior sexual outcomes at 1 year, improved urinary outcomes at 18 months, and comparable oncological outcomes at 36 months.

The Effect of Reusable Flexible Ureteroscope Aging on the Efficacy and Safety of Retrograde Intrarenal Surgery.

Purpose: Reusable flexible ureteroscopes may lose their mechanical functionality through overuse, which is known as "aging of the flexible ureteroscope." Although mechanical deterioration has been shown in several studies, the data about the effect of this situation on the efficacy and safety of retrograde intrarenal surgery (RIRS) are missing. The aim of our study was to evaluate the effect of the aging of flexible ureteroscopes on the efficacy and safety of RIRS. Methods: Patients who had undergone RIRS between 2017 and 2021 at a single center were retrospectively included in the study. Serial surgeries were performed using the same reusable flexible ureteroscope (Storz X2) until it was broken or malfunctioned because of the aging process. Group 1 was formed by the first 10 cases on whom the flexible ureteroscopes were used, representing the youngest period of the instruments, whereas group 2 was composed of the last 10 cases on whom the flexible ureteroscopes were used, representing the oldest phase of the instruments. The operative and postoperative data-including the operation time, hospitalization time, intraoperative complications, postoperative complications, and stone-free rates-were compared between the two groups. Results: A total of five flexible ureteroscopes were included in the study. The number of cases for each flexible ureteroscope ranged between 87 and 133, with a median number of 107 cases. The demographic and clinical properties of patients in both groups were similar. The operation time, lasering time, and total laser pulse were similar between the groups. The stone-free rates in group 1 and group 2 were 82.0% and 78.0%, respectively (p = 0.304). The complication rates were also similar between the groups (p = 0.591). Conclusion: The aging of reusable flexible ureteroscopes did not negatively affect the efficacy and safety of RIRS. Therefore, surgeons may use the reusable types of flexible ureteroscopes until they are totally broken.

Single-port-plus-one robot-assisted laparoscopic Lich–Gregoir direct nipple ureteral extravesical reimplantation in pediatric primary obstructive megaureter, comparing to laparoscopic cohen

PurposeTo compare the effects of a single-port-plus-one robotic laparoscopic-modified Lich–Gregoir direct nipple approach and traditional laparoscopic Cohen in treating pediatric primary obstructive megaureter.Materials and methodsThe clinical data of 24 children with primary obstructive megaureter from January 2021 to November 2021 were analyzed retrospectively. Among them, 12 children (8 boys and 4 girls, the average age were 17.17 ± 6.31 months) treated with the laparoscopic Cohen method were defined as group C. The remaining 12 children (7 boys and 5 girls, the average age was 17.33 ± 6.99 months) underwent single-port-plus-one robotic laparoscopic-modified Lich–Gregoir direct nipple ureteral extravesical reimplantation were defined as group L. The parameters of pre-operation, intraoperative and postoperative were compared.ResultsThere were no differences in the patient characteristics and average follow-up time between the two groups (P > 0.05).The obstruction resolution rate was 100% in both groups. The total operation time in group L is slightly longer than that in group C(P < 0.001),but the intraperitoneal operation time of the two groups was comparable(P > 0.05). The postoperative parameters included blood loss, gross haematuria time, indwelling catheterization time and hospitalization time in group L is shorter than group C(P < 0.05). One year post-operation, decreasing in ureteral diameter and APRPD, and increasing in DRF were remarkably observed in both two groups(P < 0.05). Ureteral diameter, APRPD, and DRF were not significantly different both in pre-operation and post-operation between Group L and Group C(P > 0.05).ConclusionSingle-port-plus-one robot-assisted laparoscopic-modified Lich–Gregoir direct nipple approach and traditional laparoscopic Cohen are both dependable techniques for ureteral reimplantation in the treatment of pediatric primary obstructive megaureter. Since Lich–Gregoir can preserve the physiological direction of the ureter and direct nipple reimplantation enhances the effect of anti-refluxing, this technique is favorable for being promoted and applied in robot surgery.

Prophylactic central lymph node dissection in cN0 papillary thyroid cancer: a comparative study of via breast and transoral approach versus via breast approach alone

BackgroundPapillary thyroid cancer (PTC) progresses slowly and has a good prognosis, while the prognosis is worse if combined with central neck lymph node metastasis at an early stage. The different endoscope approaches may affect the thoroughness of lymph node dissection. This study aimed to compare the clinical efficacy and safety of prophylactic central lymph node dissection(CLND) for cN0 PTC performed via breast and transoral approach versus via breast approach alone.Materials and methodsA retrospective analysis of the surgical data of 136 patients with stage cN0 PTC was performed from August 2020 to December 2022. Among them, 64 underwent the breast and transoral approach (combined approach group), and 72 underwent the breast approach alone (breast approach group). The relevant indexes of surgery, the number of lymph nodes dissected, the occurrence of postoperative complications, and the cosmetic satisfaction of incision were statistically compared between the two groups.ResultsThe operation time of the combined approach group was 156.4 ± 29.8 min, significantly longer than that of the breast approach group, 119.6 ± 55.9 min, and the difference was statistically significant (P&amp;lt;0.05). The two groups of patients were compared in terms of intraoperative bleeding, postoperative drainage, hospitalization time, incision cosmetic satisfaction, and the occurrence of postoperative complications, and the differences were not statistically significant (P&amp;gt;0.05). The total number of lymph nodes retrieved in the central area (10.6 ± 7.1) and the number of positive lymph nodes (4.6 ± 4.9) in the combined approach group were significantly more than those in the breast approach group (7.4 ± 4.8, 1.6 ± 2.7), and the difference was statistically significant (P&amp;lt;0.05). The difference between the two groups in terms of the number of negative lymph nodes was not statistically significant (P&amp;gt;0.05).ConclusionsThe study demonstrated that choosing the breast combined transoral approach for prophylactic CLND of cN0 PTC could more thoroughly clear the central area lymph nodes, especially the positive lymph nodes, which could help in the evaluation of the disease and the guidance of the treatment, while not increasing the postoperative complications. It provides a reference for clinicians to choose the appropriate surgical approach and also provides new ideas and methods for prophylactic CLND in patients with cN0 PTC.

Laparoscopic-assisted microwave ablation in treatment of small hepatocellular carcinoma: safety and efficacy in comparison with laparoscopic hepatectomy

Laparoscopic-assisted microwave ablation (LAMWA), as one of the locoregional therapies, has been employed to treat hepatocellular carcinoma (HCC). This study aims to compare the efficacy and safety of LAMWA and laparoscopic hepatectomy in the treatment of small HCC.This study included 140 patients who met the inclusion criteria. Among them, 68 patients received LAMWA and 72 patients underwent laparoscopic hepatectomy. The perioperative condition, liver function recovery, the alpha fetoprotein (AFP) level, morbidities, hospitalization time, overall survival (OS), disease-free survival (DFS) and recurrence rate between the two groups were compared. The rate of complete elimination of tumor tissue was 100% and the AFP level was returned to normal within 3 months after surgery in both groups (P > 0.05). The mean alanine transaminase (ALT) and aspartate transaminase (AST) peak in the LAMWA group was lower than that in the laparoscopic hepatectomy group (259.51 ± 188.75 VS 388.9 ± 173.65, P = 0.000) and (267.34 ± 190.65 VS 393.1 ± 185.67, P = 0.000), respectively. The mean operation time in the LAMWA group was shorter than that in the laparoscopic hepatectomy group (89 ± 31 min VS 259 ± 48 min, P = 0.000). The blood loss in the LAMWA group was less than that in the laparoscopic hepatectomy group (58.4 ± 64.0 ml VS 213.0 ± 108.2 ml, P = 0.000). Compared with the laparoscopic hepatectomy group, patients in the LAMWA group had lower mean hospital stay (4.8 ± 1.2d VS 11.5 ± 2.9d, P = 0.000). The morbidities of the LAMWA group and the hepatectomy group were 14.7%(10/68) and 34.7%(25/72), respectively (P = 0.006). The one-, three-, and five-year OS rates were 88.2%, 69.9%, 45.6% for the LAMWA group and 86.1%, 72.9%, 51.4% for the laparoscopic hepatectomy group (P = 0.693). The corresponding DFS rates for the two groups were 76.3%, 48.1%, 27.9% and 73.2%, 56.7%, 32.0% (P = 0.958). Laparoscopic-assisted microwave ablation is a safe and effective therapeutic option for selected small HCC.

Minimum energy laser pilonidotomy (MELPi): a multicenter study of a novel method in pilonidal disease.

Laser surgery, a minimally invasive procedure for the definitive approach to pilonidal disease (PD), has been frequently studied in recent years. This study aims to describe a new pilonidotomy method using minimal laser energy and evaluate its initial results. This is a retrospective multicenter study. We included 47 consecutive patients who underwent 50 "minimal energy pilonidotomies (MELPi)" between 2019 and 2023 in four centers in Brazil. Age, BMI, gender, smoking, diabetes, Guner classification, duration of illness, energy, hospitalization time, complications, recurrence, wound closure, pain, and return to activities were analyzed. The median age was 27; 61.7% were men, and 38.3% were women. The median BMI was 25.7. Smoking was evident in 14.9%, and diabetes in 2.1%. The average duration of the disease was 3years. Most operations (36%) were performed on stage R disease. The median hospitalization time was 6h, and the median healing time was 15days. The average energy used in procedures was 433J. The median postoperative pain was 2. Secretion occurred in 14% on the 60th day. Complications (cellulitis) occurred in 4% of cases. The median time to return to work was 7days. The average following time was 12months; recurrence occurred in 5 (10%)-in 3 patients, a second MELPi procedure was performed and was effective. MELPi shows promising initial results: low pain, low complication rates, and a fast activity return. It is a good option in recidivate cases and can be done more than once if necessary.

The Integration of Virtual Development into the Organizational Complexity of Healthcare

The development of the computer system in a hospital environment improves patients’ quality of life and allows healthcare management to evolve into the greatest virtual and functional techniques. Considering state-of-the-art devices as an aid in various highly complex surgical procedures, this gives society confidence in the services available, with continuous and rehabilitation treatments being the ones that have a greater number of technological devices helping in their favor. The contextualization aims to analyse that the inclusion of digitalization linked to virtual realities with different aspects and robotics helps to reduce hospitalization time. Methodologically, a bibliographic review was used, recommending the topic with articles that reference clinically successful research, and a Capes database was used in the search for the retrospective review. It is considered that the production describes the quality and reliability of virtual techniques and the scope of health improvement, which thus corroborates the benefits of organizational understanding in economic and care terms.

Low-grade epilepsy-associated tumors: Epilepsy outcome and antiseizure medication discontinuation after lesionectomies as first-line surgical approach in pediatric population.

This study aimed to evaluate epilepsy outcome and antiseizure medication (ASM) discontinuation after lesionectomies as first surgical approach in pediatric population diagnosed with low-grade epilepsy-associated neuroepithelial tumors (LEATs). We conducted a retrospective study. Thirty-six consecutive patients with histological diagnoses of LEATs who underwent surgery between 2018 and 2021 at our institution were included. The clinical and surgical data were retrospectively analyzed. Thirty (83.3%) of 36 patients are free of disabling seizures (Engel class I) and 19 (63,4%) of them are classified as Engel Ia. In 17 (47.2%) patients, ASM could be discontinued. The mean age at surgery was 8.6 years (±4.04) and the mean age at onset of epilepsy was 7.2 years (±3.8), whereas the mean duration of epilepsy in months at the time of surgery was 21.3 months (±23.7). The epileptogenic tumor was in the temporal lobe in 20 (55.5%) patients. Because of seizure persistence, a second or a third surgery was necessary for six patients (16.7%) and four of them had residual lesions (three in temporal and one in extratemporal site). No perioperative complications were recorded, including acute seizures, with a median hospitalization time of 7 days. Shorter epilepsy duration at time of surgery as long as a single ASM was significantly correlated with an Engel class I outcome (p-value = .01 and p-value = .016, respectively). Focal seizure semeiology was associated with an increased probability of antiseizure medication discontinuation (p-value = .042). Our findings confirm that shorter epilepsy disease duration, monotherapy before surgery, and seizure semeiology are determinant factors for a positive seizure outcome and medication discontinuation, also with less invasive surgical approaches such as lesionectomies. However, considering the intrinsic multifactorial epileptogenic nature of LEATs, a tailored surgical approach should be considered to optimize clinical and seizure outcome, especially for lesions located in the temporal lobe.

Acute coronary syndrome in elderly and senile diabetic patients

Acute coronary syndrome (ACS) remains a common cause of hospitalization in diabetes mellitus (DM) patients. It is believed that diabetic neuropathy patients have a high atypical course incidence of acute coronary syndrome, because of the frequent neuropathy development in diabetes patients, but the data on this are quite contradictory. Aim: The study aimed to determine the features of the pain syndrome and its severity in ACS and concomitant diabetes patients. Materials and Methods: The study involved 36 diabetes patients (22 men and 14 women) aged 62-86 years, hospitalized urgently for ACS. Pain syndrome was assessed during hospitalization and immediately after coronary artery revascularization using the following criteria: visual analogue scale (VAS), Numerical Rating Scale (NRS), clinical data, and biochemical markers. Results: Most of the patients (91.67%) complained of chest pain at the time of hospitalization, the rest were not bothered by any pain. Patients described pain as “burning” (30.56 %), “squeezing” (30.56 %), “tightness” (25.0 %), and “tingling” (5.56 %). There were also complaints of difficulty breathing (13.89 %), shortness of breath (11.1 %), and palpitations (41.67 %). The appearance of excessive sweating was noticed by 16.67% of patients. There was no statistically significant difference between the results of VAS and NRS pain scores (p &gt; 0.1). The mean blood glucose level at hospitalization was 8.19±3.45 mmol/l (in men – 8.17±3.61 mmol/l, in women – 8.28±3.13 mmol/L). Glycemia level higher than 10.0 mmol/l was detected in 8 patients, which accounted for 22.22% of all patients. Severe pain syndrome patients dominated in this category (62.5 %). Conclusions: In patients with myocardial infarction and diabetes, the typical clinical picture of ACS prevailed (91.67% of patients) over the painless form. Before revascularization, moderate to severe pain occurred with equal frequency; there were no statistical differences between blood pressure, heart rate, and blood glucose level (p&gt; 0.1) in patients with severe and moderate pain. Hyperglycemia (≥10.0 mmol/l) was detected in 22.22% of patients, among whom severe pain syndrome patients prevailed. _________________________________________________________________________________________ Keywords: elderly patients; diabetes mellitus; acute coronary syndrome; pain syndrome

Abstract PO5-03-01: Clinical outcomes of breast-conserving surgery under local anesthesia versus general anesthesia for breast malignancies

Abstract Clinical outcomes of breast-conserving surgery under local anesthesia versus general anesthesia for breast malignancies Hwajeong Lee, Hyunjong Jo, Eunhye Kang, Ji-Jung Jung, Ik Beom Shin, Jin Young Byeon, Changjin Lim, Hong-Kyu Kim, Hyeong-Gon Moon, Wonshik Han, Han-Byoel Lee Purpose With the increase in the incidence and proportion of stage I and in situ breast cancer, there is a growing trend for de-escalation of surgery. Several ongoing trials are evaluating the omission of sentinel lymph node biopsy (SLNB), including the SOUND trial, which showed no difference in disease-free survival. Breast-conserving surgery (BCS) under local anesthesia (LA) could be performed when no axillary surgery is necessary and could potentially reduce the physical and psychological burden on patients caused by surgery compared to BCS under general anesthesia (GA). We aim to compare the clinical outcomes between BCS under LA versus GA in patients who did not require SLNB. Methods We retrospectively collected and analyzed data from 116 patients who received BCS under LA from January 2021 to June 2023 and 260 patients who received BCS under GA in 2022. Clinical tumor size, pathologic tumor size (both including in situ carcinoma), surgical specimen volume, resection margin (RM) positivity, re-excision rate, operation time, and length of hospital stay were compared. Result There was no difference between LA and GA in terms of age, BMI, and proportion of in situ cancer. The LA group had a higher proportion of tumors with clinical tumor size ≤ 2cm. The LA group had a higher RM positive rate (11.2 vs. 5.4%, p=0.043) and re-excision rate (12.9 vs 3.5%, p &amp;lt; 0.001). According to tumor size, the higher RM positivity was only observed in clinical tumor size &amp;gt;1cm &amp; ≤ 2cm group (p=0.039). In patients whose clinical tumor size ≤ 2cm was upgraded to pathologic tumor size &amp;gt; 2cm, there was no difference in RM positivity between the two groups (5/18 [27.8%] vs. 4/34 [11.8%], p=0.247). A smaller surgical specimen volume was excised under LA (22.01 ± 14.11 vs 65.67 ± 48.43 cm3, p &amp;lt; 0.001). The overall operation time (64±16 vs 73±22 min, p &amp;lt; 0.001) and hospital stay (1 ± 0 vs 4 ± 1 days, p &amp;lt; 0.001) was shorter in the LA group Conclusion Breast-conserving surgery under LA showed a higher RM positive rate, of which most were in patients with discordance in clinical and pathologic tumor size. Although this resulted in a higher re-excision rate, the smaller surgical specimen volume, shorter operation time, and hospital stay for BCS under LA could positively impact patient recovery and quality of life. The benefits of LA should be considered when evaluating the de-escalation of surgery for breast malignancies.

Comparison of supine-prone percutaneous nephrolithotomy methods in the treatment of kidney stones in pediatric patients: prospective randomized study.

Mini-PCNL is one of the most effective surgical methods in the treatment of kidney stones in pediatric patients. In this study, we aimed to compare PCNL in the supine-prone position in pediatric patients (especially operation time, postop complications, hospital stay and stone-free rates).We conducted our study in a randomized and prospective manner. Patients with lower pole stones larger than 1cm, stones larger than 1.5cm in the pelvis, upper pole, midpole or multiple locations, and patients who did not respond to ESWL or whose family that preferred mini-PCNL to be the primary treatment were included in the study. Patients with any previous kidney stone surgery, patients with coagulation disorders and patients with retrorenal colon were excluded from the study. Between 2021 and 2023, a total of 144 patients underwent PCNL. 68 of these patients had supine PCNL and 76 prone PCNL. Postoperative Clavien grade1 complication occurred in a total of 7 patients in the prone position; Clavien grade1 complication occurred in 1 patient in the supine position. The mean operation time for prone PCNL was 119.88 ± 28.32min, and the mean operative time for supine PCNL was 98.12 ± 14.97 the mean hospitalization time in prone PCNL was 3.56 ± 1.12days, and 3.00 ± 0.85days in supine PCNL. In conclusion, supine PCNL is a safe and effective method in the treatment of pediatric kidney stones and postoperative complications were observed to be less; the operation time and hospital stay were shorter in supine PCNL.

Effect of Pretransplant Dialysis Method and Vintage on Early Clinical Outcomes of Kidney Transplantation

Pre-transplantation dialysis duration and modality may affect patients' long-term (mortality and graft failure) and short-term (delayed graft function) outcomes after kidney transplantation. We aimed to assess the impact of the method and duration of dialysis therapy on the graft function in the first 6 months post-transplant. The analysis included 122 kidney transplant patients (109 from a deceased donor and 13 from a living donor). Before transplantation, 91 were on hemodialysis (HD), 19 were on peritoneal dialysis (PD), and 9 received preemptive transplants. The incidence of delayed graft function (DGF) and creatinine levels at discharge and 6 months after transplantation were assessed. PD and HD patients did not differ in age, number of mismatches, and cold ischemia time (CIT), but they had a significantly shorter dialysis vintage (18.3 ± 25.7 vs 39.6 ± 34.3 months, P = .01) and a lower incidence of DGF (5% vs 37%, P = .006). The duration of hospitalization and creatinine concentration at discharge and after 6 months were similar. Preemptively transplanted patients had a significantly shorter CIT (ND vs DO - 576 ± 362 vs 1113 ± 574, P = .01; ND vs HD - 576 ± 362 vs 1025 ± 585 minutes, P = .01). DGF did not occur in any of the patients transplanted preemptively. They had slightly shorter hospitalization times and, compared to HD, better graft function at discharge. After 6 months, creatinine levels were comparable to HD and PD. Patients dialyzed for less than 12 months, regardless of the method, had a lower incidence of DGF. Peritoneal dialysis and a short duration of pre-transplant dialysis may improve the early results of kidney transplantation.
