Optimal interval for delayed retrieval surgery with reciprocating morcellators after enucleation of giant prostatic hyperplasia in holmium laser enucleation of the prostate

Objective:The aim of this research was to evaluate the efficiency of reciprocating morcellation for removing giant benign prostatic hyperplasia during holmium laser enucleation of the prostate,investigate whether performing morcellation as a two-stage procedure improves tissue retrieval efficiency,and seek to determine the optimal interval between the two surgeries.Methods:This study included nine cases of holmium laser enucleation of the prostate with an enucleated prostate weight exceeding 200 g,indicative of substantial prostate enlargement.Morcellation was performed on Day 0(n=4),Day 4(n=1),Day 6(n=1),and Day 7(n=3).The intervals were compared regarding the morcellation efficiency,beach ball presence,and pathology.Results:The mean estimated prostate volume was 383(range 330e528)mL;the median enucleation weight was 252(interquartile range[IQR]222,342)g;and the median enucleation time was 83(IQR 62,100)min.The mean morcellation efficiency was 1.44(SD 0.55)g/min on Day 0 and 13.69(SD 2.46)g/min on day 7.The morcellation efficiency was 4.15 g/min and 10.50 g/min on Day 4 and Day 6,respectively,with significantly higher in the two-stage group compared to one-stage group(11.0 g/min vs.1.5 g/min;p=0.014).Efficiency was strongly correlated with intervals(p<0.001);the incidences of beach balls were 100%(4/4)and 60%(3/5)in the immediate and two-stage surgery groups,respectively.Conclusion:The efficiency of two-stage morcellation with reciprocating morcellators was highly related to the postoperative interval,with the maximum efficiency reached on Day 7.

Diagnostic delay in inflammatory bowel disease increases the risk of intestinal surgery

AIM To investigate the factors affecting diagnostic delay and outcomes of diagnostic delay in inflammatory bowel disease(IBD) METHODS We retrospectively studied 165 patients with Crohn's disease(CD) and 130 patients with ulcerative colitis(UC) who were diagnosed and had follow up durations > 6 mo at Korea University Ansan Hospital from January 2000 to December 2015. A diagnostic delay was defined as the time interval between the first symptom onset and IBD diagnosis in which the 76^(th) to 100^(th) percentiles of patients were diagnosed.RESULTS The median diagnostic time interval was 6.2 and 2.4 mo in the patients with CD and UC, respectively. Among the initial symptoms, perianal discomfort before diagnosis(OR = 10.2, 95%CI: 1.93-54.3, P = 0.006) was associated with diagnostic delays in patients with CD; however, no clinical factor was associated with diagnostic delays in patients with UC. Diagnostic delays, stricturing type, and penetrating type were associated with increased intestinal surgery risks in CD(OR = 2.54, 95%CI: 1.06-6.09; OR = 4.44, 95%CI: 1.67-11.8; OR = 3.79, 95%CI: 1.14-12.6, respectively). In UC, a diagnostic delay was the only factor associated increased intestinal surgery risks(OR = 6.81, 95%CI: 1.12-41.4).CONCLUSION A diagnostic delay was associated with poor outcomes, such as increased intestinal surgery risks in patients with CD and UC.

Effect of Nalmefene on Delayed Neurocognitive Recovery in Elderly Patients Undergoing Video-assisted Thoracic Surgery with One Lung Ventilation

The intravenous use of nalmefene has been found to exert neuroprotective effect in patients with severe traumatic brain injury and acute cerebral infarction;nonetheless,it is unknown whether nalmefene alleviates delayed neurocognitive recovery.Our purpose of the current research was to clarify the impact of nalmefene on delayed neurocognitive recovery in aged patients experiencing video-assisted thoracic surgery(VATS)with intraoperative use of one lung ventilation(OLV).The present study involved 120 paticents undergoing selective VATS,randomized to accept low-dose nalmefene(N1 group,n=40),high-dose nalmefene(N2 group,1n=40)or equal volume of physiologic saline(control group,1=40).A battery of neuropsychological tests were used to estimate cognitive function I day before surgery(o)and 10 days after surgery or before discharge(t).Regional cerebral oxygen saturation(rSO2)was detected 5 min before induction(t),5 min after induction(1),15 and 60 min after onset of OLV(62 and 13),and 15 min after termination of OLV(4).The plasma values of interleukin(IL)-1β,IL-6,tumor necrosis factor(TNF)-a1 and adiponectin(ADP)were also detected prior to induction of anesthesia(T0),1 h,2 h and 6 h after surgery(TI,T2,T3).On 1,delayed neurocognitive recovery occurred in 5/40(12.5%)patients of NI group,in 5/40(12.5%)patients of N2 group and in 13/40(32.5%)patients of control group(P<0.05).There were no statistical differences in rSO2 among three groups at different time points.At Tl,T2 and T3,IL-1β,IL-6 and TNF-a values significantly increased and ADP value significantly decreased(P<0.05)in control group.In contrast,at TI,T2 and T3,IL-1β,IL-6 and TNF-a values decreased and ADP value decreased less in N1 and N2 groups(P<0.05).At TI,T2 and T3,IL-1β,IL-6 and TNF-a concentrations presented a trend of N2 group<N1 group<control group and ADP presented a trend of N2 group>Nl group>control group(P<0.05).The result of our present research supports the hypothesis that the perioperative intravenous treatment with nalmefene to VATS with OLV ameliorates postoperative cognitive function and decreases the incidence of delayed neurocognitive recovery,most likely by suppression of inflammatory responses.

Impact of surgical delay on outcomes in elderly patients undergoing emergency surgery: A single center experience

AIM: To determine predisposing factors leading to surgical delay in elderly patients with acute abdominal conditions and its impact on surgical outcomes.METHODS: A retrospective review of a total of 144 patients aged 60 years and older who had undergone emergency abdominal surgery between 2010 and 2013 at a regional general hospital was analysed. The operations analysed were limited to perforated or gangrenous viscus and strangulated hernia. Patient demographic features, time taken to obtain a computed tomography scan, time taken to surgery and the impact on postoperative morbidity and mortality were analysed.RESULTS: The mean age was 70.5 ± 9.1 years and median time taken to surgery was 9 h. The overall mortality and complication rates(Clavien Dindo 3 and above) were 9% and 13.1% respectively. Diabetes mellitus was a significant predisposing factor which had an impact on surgical delays. Delays in surgery more than 24 h led to higher complication rates at 38.9%(P = 0.003), with multivariate analysis confirming it as an independent factor. Delays in obtaining a computed tomography(CT) scan was also shown to result in higher complication rates(Clavien Dindo 3 and above).CONCLUSION: Delays in performing emergency surgery in elderly lead to higher complication rates. Obtaining CT scans early also may facilitate prompt diagnosis of certain abdominal emergencies where presentation is more equivocal and this may lead to improved surgical outcomes.

Risk factors for postoperative delayed gastric emptying in ovarian cancer treated with cytoreductive surgery and hyperthermic intraperitoneal chemotherapy

BACKGROUND Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy(CRSHIPEC)has shown promising results in improving the survival of ovarian cancer patients.Although the safety profiles of CRS-HIPEC exist,more attention should be paid to gastrointestinal complications,as the procedure involves a considerable proportion of bowel resection and anastomosis.AIM To identify the risk factors for delayed gastric emptying in ovarian cancer treated with CRS-HIPEC.METHODS A cross-sectional study was conducted.According to the inclusion and exclusion criteria,we retrospectively analyzed 77 patients admitted between March 2014 and April 2018 with advanced and recurrent ovarian cancer treated with CRSHIPEC in Beijing Shijitan Hospital of Capital Medical University.Risk factors for delayed gastric emptying were analyzed using univariate analysis.All of the statistically significant variables in the univariate analysis were entered into the multivariable logistic regression model to determine factors independently associated with delayed gastric emptying.RESULTS Among the 77 included patients,36.4%(28/77)had delayed gastric emptying after CRS-HIPEC.The median age and body mass index of all patients were 59 years and 22.83 kg/m^(2),respectively.Preoperative chemotherapy was administered in 55 patients(71%).Sixty-two patients(81%)had a history of at least one previous pelvic surgery.The median operation time and intraoperative hemorrhage volume were 630 min and 600 mL,respectively.Omentectomy was performed in 32 cases of primary ovarian cancer and 24 cases of recurrence.The median peritoneal cancer index was 16.The risk factors for delayed gastric emptying from the univariate analysis were body mass index<23 kg/m2(X2=5.059,P=0.025),history of pelvic surgery(X^(2)=4.498,P=0.034),history of chemotherapy(X^(2)=4.334,P=0.037),operation time≥7 h(X2=4.827,P=0.047),and intraoperative hemorrhage≥800 mL(X^(2)=7.112,P=0.008).Multivariable analysis revealed that age≥70 years(HR=7.127;95%CI 1.122-45.264;P=0.037)and intraoperative hemorrhage≥800 mL(HR=3.416;95%CI 1.067-10.939;P=0.039)were independently associated with postoperative delayed gastric emptying after CRS-HIPEC.CONCLUSION Postoperative gastrointestinal management,including prolonged nasogastric intubation,should be promoted for patients over 70 years or those with intraoperative bleeding exceeding 800 mL.

Enhanced recovery after surgery pathway: The use of fascia iliaca blocks causes delayed ambulation after total hip arthroplasty

BACKGROUND Fascia iliaca compartment blocks(FIBs) have been used to provide postoperative analgesia after total hip arthroplasty(THA). However, evidence of their efficacy remains limited. While pain control appears to be satisfactory, quadriceps weakness may be an untoward consequence of the block. Prior studies have shown femoral nerve blocks and fascia iliaca blocks as being superior for pain control and ambulation following THA when compared to standard therapy of parenteral pain control. However, most studies allowed patients to ambulate on post-operative day(POD) 2-3, whereas new guidelines suggest ambulation on POD 0 is beneficial.AIM To determine the effect of FIB after THA in patients participating in an enhanced recovery after surgery(ERAS) program.METHODS We conducted a retrospective analysis of patients undergoing THA with or without FICBs and their ability to ambulate on POD 0 in accordance with ERAS protocol. Perioperative data was collected on 39 patients who underwent THA.Demographic data, anesthesia data, and ambulatory outcomes were compared.RESULTS Twenty patients had FIBs placed at the conclusion of the procedure, while 19 did not receive a block. Of the 20 patients with FIB, only 1 patient was able to ambulate. Of the 19 patients without FIB blocks, 17 were able to ambulate. All patients worked with physical therapy 2 h after arriving in the post-anesthesia care unit on POD 0.CONCLUSION Our data suggests an association between FIB and delayed ambulation in the immediate post-operative period.

Surgery for Crohn's disease in the era of biologicals:A reduced need or delayed verdict?

Crohn's disease(CD) is a chronic inflammatory bowel disease that can affect the entire gastrointestinal tract.Ultimately,up to 70% of all patients will need surgery,despite optimized medical therapy.Moreover,about half of the patients will need redo-surgery because of disease recurrence.The introduction of anti-tumor necrosis factor(TNF) drugs(Infliximab in 1998) revolutionized the treatment of CD.Different randomized trials assessed the efficacy of anti-TNF treatment not only to induce,but also to maintain,steroid-free remission.Furthermore,these agents can rapidly lead to mucosal healing.This aspect is important,as it is a major predictor for long-term disease control.Subgroup analyses of responding patients seemed to suggest a reduction in the need for surgery at median-term follow up(1-3 years).However if one looks at population surveys,one does not observe any decline in the need for surgery since the introduction of Infliximab in 1998.The short follow-up term and the exclusion of patients with imminent surgical need in the randomized trials could bias the results.Only 60% of patients respond to induction of anti-TNF therapy,moreover,some patients will actually develop resistance to biologicals.Many patients are diagnosed when stenosing disease has already occurred,obviating the need for biological therapy.In a further attempt to change the actual course of the disease,top down strategies have been progressively implemented.Whether this will indeed obviate surgery for a substantial group of patients remains unclear.For the time being,surgery will still play a pivotal role in the treatment of CD.

Interventional treatment options for management of delayed arterial hemorrhage after major hepato-pancreatic-biliary surgery

Hilar cholangiocarcinoma is a biliary malignancy arising from the perihilar biliary tree,which is associated with poor oncological outcomes due to its aggressive biology,chemo-resistance and insidious onset[1].As stated by Di Martino et al.,the standard of care is radical resection,and during the last decades,there have been great efforts to improve survival of potentially resectable hilar cholangiocarcinoma,with surgery being the treatment associated with longer survival[2].However,radical resection still represents a challenging operation with high risk of intraoperative and postoperative complications.

The International Study Group of Pancreatic Surgery definition of delayed gastric emptying and the effects of various surgical modifications on the occurrence of delayed gastric emptying after pancreatoduodenectomy

BACKGROUND:A number of definitions have been used for delayed gastric emptying(DGE) after pancreatoduodenectomy and the reported rates varied widely.The International Study Group of Pancreatic Surgery(ISGPS) definition is the current standard but it is not used universally.In this comprehensive review,we aimed to determine the acceptance rate of ISGPS definition of DGE,the incidence of DGE after pancreatoduodenectomy and the effect of various technical modifications on its incidence.DATA SOURCE:We searched PubM ed for studies regarding DGE after pancreatoduodenectomy that were published from 1 January 1980 to 1 July 2015 and extracted data on DGE definition,DGE rates and comparison of DGE rates among different technical modifications from all of the relevant articles.RESULTS:Out of 435 search results,178 were selected for data extraction.The ISGPS definition was used in 80% of the studies published since 2010 and the average rates of DGE and clinically relevant DGE were 27.7%(range:0-100%;median:18.7%) and 14.3%(range:1.8%-58.2%;median:13.6%),respectively.Pylorus preservation or retrocolic reconstruction were not associated with increased DGE rates.Although pyloric dilatation,Braun’s entero-enterostomy and Billroth Ⅱ reconstruction were associated with significantly lower DGE rates,pyloric ring resection appears to be most promising with favorable results in 7 out of 10 studies.CONCLUSIONS:ISGPS definition of DGE has been used in majority of studies published after 2010.Clinically relevant DGE rates remain high at 14.3% despite a number of proposed surgical modifications.Pyloric ring resection seems to offer the most promising solution to reduce the occurrence of DGE.

Indocyanine green:The guide to safer and more effective surgery

In this editorial we comment on the article by Kalayarasan and co-workers published in the recent issue of the World Journal of Gastrointestinal Surgery.The authors present an interesting review on the use of indocyanine green fluo-rescence in different aspects of abdominal surgery.They also highlight future perspectives of the use of indocyanine green in mini-invasive surgery.Indo-cyanine green,used for fluorescence imaging,has been approved by the Food and Drug Administration and is safe for use in humans.It can be administered in-travenously or intra-arterially.Since its advent,there have been several advance-ments in the applications of indocyanine green,especially in the surgical field,such as intraoperative mapping and biopsy of sentinel lymph node,measurement of hepatic function prior to resection,in neurosurgical cases to detect vascular anomalies,in cardiovascular cases for patency and assessment of vascular ab-normalities,in predicting healing following amputations,in helping visualization of hepatobiliary anatomy and blood vessels,in reconstructive surgery,to assess flap viability and for the evaluation of tissue perfusion following major trauma and burns.For these reasons,the intraoperative use of indocyanine green has become common in a variety of surgical specialties and transplant surgery.Co-lorectal surgery has just lately begun to adopt this technique,particularly for perfusion visualization to prevent anastomotic leakage.The regular use of in-docyanine green coupled with fluorescence angiography has recently been pro-posed as a feasible tool to help improve patient outcomes.Using the best available data,it has been shown that routine use of indocyanine green in colorectal surgery reduces the rates of anastomotic leak.The use of indocyanine green is proven to be safe,feasible,and effective in both elective and emergency scenarios.However,additional robust evidence from larger-scale,high-quality studies is essential before incorporating indocyanine green guided surgery into standard practice.

New direction for surgery:Super minimally invasive surgery

The top goal of modern medicine is treating disease without destroying organ structures and making patients as healthy as they were before their sickness.Minimally invasive surgery(MIS)has dominated the surgical realm because of its lesser invasiveness.However,changes in anatomical structures of the body and reconstruction of internal organs or different organs are common after traditional surgery or MIS,decreasing the quality of life of patients post-operation.Thus,I propose a new treatment mode,super MIS(SMIS),which is defined as“curing a disease or lesion which used to be treated by MIS while preserving the integrity of the organs”.In this study,I describe the origin,definition,operative channels,advantages,and future perspectives of SMIS.

Pulmonary embolism after shoulder surgery:Is it a real threat?

Pulmonary embolism(PE)is a rare but devastating complication of shoulder surgery.Apart from increased morbidity and mortality rates,it may significantly impair postoperative recovery and functional outcome.Its frequency accounts for up to 5.7%of all shoulder surgery procedures with a higher occurrence in women and patients older than 70 years.It is most commonly associated with thrombophilia,diabetes mellitus,obesity,smoking,hypertension,and a history of malignancy.PE usually occurs secondary to upper or lower-extremity deep vein thrombosis(DVT).However,in rare cases,the source of the thrombi cannot be determined.Prophylaxis for PE following shoulder surgery remains a topic of debate,and the standard of care does not routinely require prophylactic medication for DVT prophylaxis.Early ambulation and elastic stockings are important preventative measures for DVT of the lower extremity and medical agents such as aspirin,low-molecular-weight heparin,and vitamin K antagonists are indicated for high-risk patients,long-lasting operations,or concomitant severe acute respiratory syndrome coronavirus 2 infection.The most common symptoms of PE include chest pain and shortness of breath,but PE can also be asymptomatic in patients with intrinsic tolerance of hypoxia.Patients with DVT may also present with swelling and pain of the respective extremity.The treatment of PE includes inpatient or outpatient anticoagulant therapy if the patient is hemodynamically unstable or stable,respectively.Hemodynamic instability may require transfer to the intensive care unit,and cardiovascular arrest can be implicated in fatal events.An important issue for patients with PE in the postoperative period after shoulder surgery is residual stiffness due to a delay in rehabilitation and a prolonged hospital stay.Early physiotherapy and range-of-motion exercises do not adversely affect the prognosis of PE and are highly recommended to preserve shoulder mobility and function.

Managerial perspectives of scaling up robotic-assisted surgery in healthcare systems:A systematic literature review

Objectives Robotic-assisted surgery(RAS)is a minimally invasive technique practiced in multiple specialties.Standard training is essential for the acquisition of RAS skills.The cost of RAS is considered to be high,which makes it a burden for institutes and unaffordable for patients.This systematic literature review(SLR)focused on the various RAS training methods applied in different surgical specialties,as well as the cost elements of RAS,and was to summarize the opportunities and challenges associated with scaling up RAS.Methods An SLR was carried out based on the Preferred Reporting Items for Systematic reviews and Meta-Analyses reporting guidelines.The PubMed,EBSCO,and Scopus databases were searched for reports from January 2018 through January 2024.Full-text reviews and research articles in the English language from Asia-Pacific countries were included.Articles that outlined training and costs associated with RAS were chosen.Results The most common training system is the da Vinci system.The simulation technique,which includes dry-lab,wet-lab,and virtual reality training,was found to be a common and important practice.The cost of RAS encompasses the installation and maintenance costs of the robotic system,the operation theatre rent,personnel cost,surgical instrument and material cost,and other miscellaneous charges.The synthesis of SLR revealed the challenges and opportunities regarding RAS training and cost.Conclusions The results of this SLR will help stakeholders such as decision-makers,influencers,and end users of RAS to understand the significance of training and cost in scaling up RAS from a managerial perspective.For any healthcare innovation to reach a vast population,cost-effectiveness and standard training are crucial.

Attosecond ionization time delays in strong-field physics

Electronic processes within atoms and molecules reside on the timescale of attoseconds. Recent advances in the laserbased pump-probe interrogation techniques have made possible the temporal resolution of ultrafast electronic processes on the attosecond timescale, including photoionization and tunneling ionization. These interrogation techniques include the attosecond streak camera, the reconstruction of attosecond beating by interference of two-photon transitions, and the attoclock. While the former two are usually employed to study photoionization processes, the latter is typically used to investigate tunneling ionization. In this review, we briefly overview these timing techniques towards an attosecond temporal resolution of ionization processes in atoms and molecules under intense laser fields. In particular, we review the backpropagation method, which is a novel hybrid quantum-classical approach towards the full characterization of tunneling ionization dynamics. Continued advances in the interrogation techniques promise to pave the pathway towards the exploration of ever faster dynamical processes on an ever shorter timescale.

Safety and feasibility of enhanced recovery after surgery-based management model for ambulatory pediatric surgical procedures

BACKGROUND There is still some room for optimizing ambulatory pediatric surgical procedures,and the preoperative and postoperative management quality for pediatric patients needs to be improved.AIM To discuss the safety and feasibility of the enhanced recovery after surgery(ERAS)-based management model for ambulatory pediatric surgical procedures.METHODS We selected 320 pediatric patients undergoing ambulatory surgery from June 2023 to January 2024 at The First People’s Hospital of Liangshan Yi Autonomous Prefecture.Of these,220 received ERAS-based management(research group)and 100 received routine management(control group).General information,postoperative ambulation activities,surgical outcomes(operation time,postoperative gastro-intestinal ventilation time,and hospital stay),postoperative pain visual analogue scale,postoperative complications(incision infection,abdominal distension,fever,nausea,and vomiting),and family satisfaction were compared.RESULTS The general information of the research group(sex,age,disease type,single parent,family history,etc.)was comparable to that of the control group(P>0.05),but the rate of postoperative(2 h,4 h,and 6 h after surgery)ambulation activities was statistically higher(P<0.01),and operation time,postoperative gastrointestinal ventilation time,and hospital stay were markedly shorter(P<0.05).The research group had lower visual analogue scale scores(P<0.01)at 12 h and 24 h after surgery and a lower incidence of total postoperative complications than the control group(P=0.001).The research group had higher family satisfaction than the control group(P=0.007).CONCLUSION The ERAS-based management model was safe and feasible in ambulatory pediatric surgical procedures and worthy of clinical promotion.

Trend of robot-assisted surgery system in gastrointestinal and liver surgery: A bibliometric analysis

BACKGROUND Robot-assisted gastrointestinal and liver surgery has been an important development direction in the field of surgery in recent years and it is also one of the fastest developing and most concerning fields in surgical operations.AIM To illustrate the major areas of research and forward-looking directions over the past twenty-six years.METHODS Using the Web of Science Core Collection database,a comprehensive review of scholarly articles pertaining to robot-assisted gastrointestinal and liver surgery was researched out between 2000 and 2023.We used Citespace(Version 6.2.4)and Bibliometrix package(Version 4.3.0)to visualize the analysis of all publications including country,institutional affiliations,authors,and keywords.RESULTS In total,346 articles were retrieved.Surgical Endoscopy had with the largest number of publications and was cited in this field.The United States was a core research country in this field.Yonsei University was the most productive institution.The current focus of this field is on rectal surgery,long-term prognosis,perioperative management,previous surgical experience,and the learning curve.CONCLUSION The scientific interest in robot-assisted gastrointestinal and liver surgery has experienced a significant rise since 1997.This study provides new perspectives and ideas for future research in this field.

Does enhanced recovery after surgery programs improve clinical outcomes in liver cancer surgery?

Enhanced recovery after surgery(ERAS)programs have been widely applied in liver surgery since the publication of the first ERAS guidelines in 2016 and the new recommendations in 2022.Liver surgery is usually performed in oncological patients(liver metastasis,hepatocellular carcinoma,cholangiocarcinoma,etc.),but the real impact of liver surgery ERAS programs in oncological outcomes is not clearly defined.Theoretical advantages of ERAS programs are:ERAS decreases postoperative complication rates and has been demonstrated a clear relationship between complications and oncological outcomes;a better and faster posto-perative recovery should let oncologic teams begin chemotherapeutic regimens on time;prehabilitation and nutrition actions before surgery should also improve the performance status of the patients receiving chemotherapy.So,ERAS could be another way to improve our oncological results.We will discuss the literature about liver surgery ERAS focusing on its oncological implications and future investigations projects.

Exploring the landscape of minimally invasive pancreatic surgery: Progress, challenges, and future directions

Minimally invasive surgery(MI)has become the standard of care for many surgical procedures aimed at reducing the burden on patients.However,its adoption in pancreatic surgery(PS)has been limited by the pancreas’s unique location and the complexity of the dissection and reconstruction phases.These factors continue to contribute to PS having one of the highest morbidity and mortality rates in general surgery.Despite a rough start,MIPS has gained widespread acceptance in clinical practice recently.Robust evidence supports MI distal pancreatectomy safety,even in oncological cases,indicating its potential superiority over open surgery.However,definitive evidence of MI pancre-aticoduodenectomy(MIPD)feasibility and safety,particularly for malignant lesions,is still lacking.Nonetheless,reports from high-volume centers are emer-ging,suggesting outcomes comparable to those of the open approach.The robotic PS increasing adoption,facilitated by the wider availability of robotic platforms,may further facilitate the transition to MIPD by overcoming the technical con-straints associated with laparoscopy and accelerating the learning curve.Alth-ough the MIPS implementation process cannot be stopped in this evolving world,ensuring patient safety through strict outcome monitoring is critical.Investing in younger surgeons with structured and recognized training programs can promote safe expansion.

Transurethral prostate surgery in prostate cancer patients: A population-based comparative analysis of complication and mortality rates

Objective:Prostate cancer(PCa)patients might experience lower urinary tract symptoms as those diagnosed with benign prostatic hyperplasia(BPH).Some of them might be treated for their lower urinary tract symptoms instead of PCa.We aimed to test the effect of PCa versus BPH on surgical outcomes after transurethral prostate surgery,namely complication and mortality rates.Methods:Within the American College of Surgeons National Surgical Quality Improvement Program database(2011-2016),we identified patients who underwent transurethral resection of the prostate,photoselective vaporization,or laser enucleation.Patients were stratified according to postoperative diagnosis(PCa vs.BPH).Univariable and multivariable logistic regression models evaluated the predictors of perioperative morbidity and mortality.A formal test of interaction between diagnosis and surgical technique used was performed.Results:Overall,34542 patients were included.Of all,2008(5.8%)had a diagnosis of PCa.The multivariable logistic regression model failed to show statistically significant higher rates of postoperative complications in PCa patients(odds ratio:0.9,95%confidence interval:0.7-1.1;p=0.252).Moreover,similar rates of perioperative mortality(p=0.255),major acute cardiovascular events(p=0.581),transfusions(p=0.933),and length of stay of more than or equal to 30 days(p=0.174)were found.Additionally,all tests failed to show an interaction between post-operative diagnosis and surgical technique used.Conclusion:Patients diagnosed with PCa do not experience higher perioperative morbidity or mortality after transurethral prostate surgery when compared to their BPH counterparts.Moreover,the diagnosis seems to not influence surgical technique outcomes.

Impact of fast-track surgery on perioperative care in patients undergoing hepatobiliary surgery

BACKGROUND Fast-track surgery(FTS)is a modern nursing approach that has gained popularity in the perioperative phase of surgery.AIM To investigate the impact of FTS on perioperative care for hepatobiliary surgery.METHODS A retrospective analysis was performed on 98 patients who underwent hepato-biliary surgery and were admitted to our hospital from August 2021 to October 2023.They were divided into an observation group and a control group with 49 patients in each group according to different nursing directions.The control group was treated with standard nursing and the observation group was treated with FTS concept nursing.The length of hospital stay,visual analog scale(VAS)score,wound complications,nursing satisfaction,self-rating scale(SAS)score,and SF-36 quality of life(QoL)score were compared between the two groups before and after care.RESULTS The duration of hospitalization,hospitalization cost,operation time,first im-plantation time,exhaust time,and first defecation time were shorter than the observation group(P<0.05).Additionally,the observation group showed a sig-nificant difference between the VAS and SAS scores on days 1,3,and 7(P<0.05).The complication rate in the observation group was 4.05%was significantly lower than the 18.36%in the control group,and the comparison groups were statistically significant(χ2=5.018,P=0.025).The observation group had a significantly higher level of nurse satisfaction(94.92%)than the control group(79.59%;χ2=6.078,P=0.014).Both groups showed higher QoL scores after nursing care,with higher scores in the observation group than in the control group(P=0.032).CONCLUSION FTS in patients undergoing hepatobiliary surgery can effectively improve negative mood,QoL,and nursing sa-tisfaction;reduce wound complications;and accelerate patient rehabilitation.
