Global geoepidemiology of gastrointestinal surgery rates in Crohn’s disease

BACKGROUND Data regarding the worldwide gastrointestinal surgery rates in patients with Crohn’s disease(CD)remains limited.AIM To systematically review the global variation in the rates of surgery in CD.METHODS A comprehensive search analysis was performed using multiple electronic databases from inception through July 1,2020,to identify all full text,randomized controlled trials and cohort studies pertaining to gastrointestinal surgery rates in adult patients with CD.Outcomes included continent based demographic data,CD surgery rates over time,as well as the geoepidemiologic variation in CD surgery rates.Statistical analyses were conducted using R.RESULTS Twenty-three studies spanning four continents were included.The median proportion of persons with CD who underwent gastrointestinal surgery in studies from North America,Europe,Asia,and Oceania were 30%(range:1.7%-62.0%),40%(range:0.6%-74.0%),17%(range:16.0%-43.0%),and 38%respectively.No clear association was found regarding the proportion of patients undergoing gastrointestinal surgery over time in North America(R^(2)=0.035)and Europe(R^(2)=0.100).A moderate,negative association was seen regarding the proportion of patients undergoing gastrointestinal surgery over time(R^(2)=0.520)in Asia.CONCLUSION There appears to be significant inter-continental variation regarding surgery rates in CD.Homogenous evidencebased guidelines accounting for the geographic differences in managing patients with CD is prudent.Moreover,as a paucity of data on surgery rates in CD exists outside the North American and European continents,future studies,particularly in less studied locales,are warranted.

Comparative observation of the effectiveness and safety of remimazolam besylate versus dexmedetomidine in gastrointestinal surgery in obese patients

BACKGROUND Surgery for obese patients carries a higher risk of anesthesia complications compared with surgery for nonobese patients.Thus,a safe and effective anesthesia strategy is necessary to improve the medical experience of such patients and ensure their safety.AIM To compared the effectiveness and safety of remimazolam besylate versus dexmedetomidine(DEX)in gastrointestinal surgery in obese patients.METHODS The study cohort included 60 obese patients undergoing gastrointestinal surgery between July 2021 and April 2023,comprising 30 patients who received DEX intervention(control group)and 30 patients who received remimazolam besylate intervention(research group).Heart rate(HR),respiratory rate(RR),mean arterial pressure(MAP),blood oxygen saturation(SpO_(2)),safety(nausea and vomiting,bradycardia,hypotension,and apnea),anesthesia and examination indices[induction time,anesthesia recovery time,and postanesthesia care unit(PACU)discharge time],sedation effect(Ramsay Sedation Scale),and postoperative pain visual analog scale were comparatively analyzed before anesthesia(T0),during anesthesia(T1),and after anesthesia(T2).RESULTS At T1,the research group showed significantly smaller changes in HR,RR,MAP,and SpO_(2) than the control group,with a significantly lower adverse reaction rate and shorter induction,anesthesia recovery,and PACU discharge times.Additionally,the intra-and postoperative Ramsay Sedation Scale scores were statistically higher in the research group than in the control group.CONCLUSION Remimazolam besylate was significantly more effective than DEX in gastrointestinal surgery in obese patients and had a higher safety profile and value in clinical promotion.

From the mathematical model to the patient: The scientific and human aspects of artificial intelligence in gastrointestinal surgery

Recent medical literature shows that the application of artificial intelligence(AI)models in gastrointestinal pathology is an exponentially growing field,with pro-mising models that show very high performances.Regarding inflammatory bowel disease(IBD),recent reviews demonstrate promising diagnostic and prognostic AI models.However,studies are generally at high risk of bias(especially in AI models that are image-based).The creation of specific AI models that improve diagnostic performance and allow the establishment of a general prognostic fo-recast in IBD is of great interest,as it may allow the stratification of patients into subgroups and,in turn,allow the creation of different diagnostic and therapeutic protocols for these patients.Regarding surgical models,predictive models of post-operative complications have shown great potential in large-scale studies.In this work,the authors present the development of a predictive algorithm for early post-surgical complications in Crohn's disease based on a Random Forest model with exceptional predictive ability for complications within the cohort.The pre-sent work,based on logical and reasoned,clinical,and applicable aspects,lays a solid foundation for future prospective work to further develop post-surgical prognostic tools for IBD.The next step is to develop in a prospective and mul-ticenter way,a collaborative path to optimize this line of research and make it applicable to our patients.

Remazolam combined with transversus abdominis plane block in gastrointestinal tumor surgery:Have we achieved better anesthetic effects?

Laparoscopic surgery is the main treatment method for patients with gastrointestinal malignant tumors.Although laparoscopic surgery is minimally invasive,its tool stimulation and pneumoperitoneum pressure often cause strong stress reactions in patients.On the other hand,gastrointestinal surgery can cause stronger pain in patients,compared to other surgeries.Transversus abdominis plane block(TAPB)can effectively inhibit the transmission of nerve impulses caused by surgical stimulation,alleviate patient pain,and thus alleviate stress reactions.Remazolam is an acting,safe,and effective sedative,which has little effect on hemodynamics and is suitable for most patients.TAPB combined with remazolam can reduce the dosage of total anesthetic drugs,reduce adverse reactions,reduce stress reactions,and facilitate the rapid postoperative recovery of patients.

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.

The effect of intraoperative goal-directed fluid therapy in patients under anesthesia for gastrointestinal surgery

BACKGROUND Intraoperative fluid management is an important aspect of anesthesia mana-gement in gastrointestinal surgery.Intraoperative goal-directed fluid therapy(GDFT)is a method for optimizing a patient's physiological state by monitoring and regulating fluid input in real-time.AIM To evaluate the efficacy of intraoperative GDFT in patients under anesthesia for gastrointestinal surgery.METHODS This study utilized a retrospective comparative study design and included 60 patients who underwent gastrointestinal surgery at a hospital.The experimental group(GDFT group)and the control group,each comprising 30 patients,received intraoperative GDFT and traditional fluid management strategies,respectively.The effect of GDFT was evaluated by comparing postoperative recovery,com-plication rates,hospitalization time,and other indicators between the two patient groups.RESULTS Intraoperative blood loss in the experimental and control groups was 296.64±46.71 mL and 470.05±73.26 mL(P<0.001),and urine volume was 415.13±96.72 mL and 239.15±94.69 mL(P<0.001),respectively.The postoperative recovery time was 5.44±1.1 days for the experimental group compared to 7.59±1.45 days(P<0.001)for the control group.Hospitalization time for the experimental group was 10.87±2.36 days vs 13.65±3 days for the control group(P<0.001).The visual analogue scale scores of the experimental and control groups at 24 h and 48 h INTRODUCTION Gastrointestinal surgery is one of the most common procedures in the field of general surgery[1],involving the stomach,intestines,liver,pancreas,spleen,and other internal abdominal organs[2,3].With advancements in surgical technology and anesthesia methods,the safety and success rates of surgery have significantly improved[4,5].However,intraop-erative fluid management remains a critical challenge[6].Traditional fluid management strategies often rely on experience and basic physiological parameters,which may lead to excessive or insufficient fluid input,thereby affecting postoperative recovery and complication rates.Intraoperative goal-directed fluid therapy(GDFT)is an emerging fluid management strategy that dynamically adjusts fluid input volume by monitoring the patient's hemodynamic parameters in real-time to optimize the patient's physiological state[7,8].GDFT has shown superiority in many surgical fields;however,its application in gastrointestinal surgery requires further research and verification[9,10].The application of intraoperative GDFT in clinical settings has gradually increased in recent years[11,12].Studies have demonstrated that GDFT can optimize tissue perfusion and oxygenation by precisely controlling fluid input and reducing the occurrence of postoperative complications[13,14].For example,in cardiac and major vascular surgeries,GDFT significantly reduced the incidence of postoperative acute kidney injury and cardiovascular events[15,16].Similarly,in abdominal surgery,GDFT effectively reduced postoperative infections and expedited recovery[17].However,studies on the utilization of GDFT in gastrointestinal surgery are relatively limited and they are confounded by contradictory findings[18].Traditional fluid management strategies typically rely on estimating fluid input volume based on the patient's weight,preoperative status,and basic physiological parameters[19].However,this method lacks real-time dynamic adjustment,which may result in either insufficient or excessive fluid input,consequently affecting postoperative recovery.Insufficient fluid input can lead to hypovolemia and inadequate tissue perfusion,whereas excessive fluid input can cause tissue edema and postoperative complications,such as pulmonary edema and heart failure.GDFT involves dynamically adjusting fluid input volume by monitoring the patient's hemodynamic parameters in real-time,such as cardiac output,pulse pressure variability,and central venous pressure.Commonly used monitoring equipment include esophageal Doppler and pulse wave profile analyzers[20].These devices provide real-time hemo-dynamic data to assist anesthesiologists in tailoring fluid therapy to a patient's specific condition.Firstly,the patient's volume responsiveness is assessed by preloading fluid;secondly,fluid input volume is dynamically adjusted based on real-time monitoring data;finally,vasoactive and inotropic drugs are administered in combination to further optimize the patient’s hemodynamic status.Through personalized fluid management,GDFT can more accurately maintain intraop-erative hemodynamic stability and reduce complications[21].Gastrointestinal surgery involves procedures on multiple organs,often requiring prolonged operative times and extensive tissue trauma,which presents challenges for intraop-erative fluid management.Surgical procedures can lead to significant bleeding and fluid loss,requiring prompt and effective fluid replenishment.In addition,the slow recovery of gastrointestinal function after surgery and susceptibility to complications such as intestinal obstruction and delayed gastric emptying elevate the necessity for postoperative fluid management.

Practical effect of different teaching modes in teaching gastrointestinal surgery nursing

BACKGROUND With the continuous development and progress of medical technology,the position of surgical nursing in the field of clinical medicine is becoming in-creasingly prominent.As an important branch of the surgical field,the nursing requirements and difficulty of gastrointestinal surgery are also increasing.In order to improve the teaching quality of nursing care in gastrointestinal surgery,many educators and researchers are actively exploring new teaching methods.Among them,the teaching method case-based learning(CBL),scene-simulated learning(SSL),task-based learning(TBL),combining self-evaluation and training mode is considered as an effective method.This method aims to help students to better master knowledge and skills and improve their comprehensive quality by cultivating their self-evaluation ability.AIM To explore the practical effect of CBL-SSL-TBL combined with training mode and student self-assessment in nursing teaching of gastrointestinal surgery.METHODS Seventy-one nursing interns in our hospital from December 2020 to December 2021 were selected.According to different teaching modes,they were divided into observation group CBL-SSL-TBL combined with training mode combined with student self-assessment and control group(conventional teaching mode),of which 36 were in observation group and 35 were in control group.The results of operational skills,theoretical knowledge,nursing students'satisfaction,learning effectiveness questionnaire and teaching effect were compared between the two groups.RESULTS Compared between the two groups,the operational skills and theoretical knowledge scores of the observation group were higher than those of the control group,and the difference was statistically significant(P<0.05).Compared between the two groups,the total satisfaction ratio of the observation group was higher than that of the control group,the difference was statistically significant(P<0.05).Compared between the two groups,the observation group was lower than the control group in the questionnaire results of learning efficacy,and the difference was statistically significant(P<0.05).Compared between the two groups,the proportion of thinking ability,subjective initiative and understanding of theoretical knowledge in the observation group was higher than that in the control group,the difference was statistically significant(P<0.05).CONCLUSION The use of CBL-SSL-TBL combined with training mode and student self-assessment in gastrointestinal surgery nursing teaching can improve the operational skills of nursing interns,theoretical knowledge and satisfaction scores of nursing students,improve the results of learning efficiency questionnaire and teaching effect,which can be popularized in clinical teaching.

Prognostic factors associated with gastrointestinal dysfunction after gastrointestinal tumor surgery:A meta-analysis

BACKGROUND Explore the risk factors of gastrointestinal dysfunction after gastrointestinal tumor surgery and to provide evidence for the prevention and intervention of gastrointestinal dysfunction in patients with gastrointestinal tumor surgery.AIM To investigate the potential risk factors for gastrointestinal dysfunction following gastrointestinal tumor surgery and to present information supporting the prevention and management of gastrointestinal dysfunction in surgery patients.METHODS Systematically searched the relevant literature from PubMed,Web of Science,Cochrane Library,Embase,CNKI,China Biomedical Database,Wanfang Database,and Weipu Chinese Journal Database self-established until October 1,2022.Review Manager 5.3 software was used for meta-analysis after two researchers independently screened literature,extracted data,and evaluated the risk of bias in the included studies.RESULTS A total of 23 pieces of literature were included,the quality of which was medium or above,and the total sample size was 43878.The results of meta-analysis showed that the patients were male(OR=1.58,95%CI:1.25-2.01,P=0.002)and≥60 years old(OR=2.60,95%CI:1.76-2.87,P<0.001),physical index≥25.3 kg/m2(OR=1.6,95%CI:1.00-1.12,P=0.040),smoking history(OR=1.89,95%CI:1.31-2.73,P<0.001),chronic obstructive pulmonary disease(OR=1.49,95%CI:1.22-1.83,P<0.001),enterostomy(OR=1.47,95%CI:1.26-1.70,P<0.001),history of abdominal surgery(OR=2.90,95%CI:1.67-5.03,P<0.001),surgical site(OR=1.2,95%CI:1.40-2.62,P<0.001),operation method(OR=1.68,95%CI:1.08-2.62,P=0.020),operation duration(OR=2.65,95%CI:1.92-3.67,P<0.001),abdominal adhesion grade(OR=2.52,95%CI:1.90-3.56,P<0.001),postoperative opioid history(OR=5.35,95%CI:3.29-8.71,P<0.001),tumor TNM staging(OR=2.58,95%CI:1.84-3.62,P<0.001),postoperative blood transfusion(OR=2.92,95%CI:0.88-9.73,P=0.010)is a risk factor for postoperative gastrointestinal dysfunction in patients with gastrointestinal tumors.CONCLUSION There are many factors affecting gastrointestinal dysfunction in gastrointestinal patients after surgery.Clinical staff should identify relevant risk factors early and implement targeted intervention measures on the basis of personalized assessment to improve the clinical prognosis of patients.

Role of artificial intelligence in gastrointestinal surgery

Artificial intelligence is rapidly evolving and its application is increasing day-byday in the medical field.The application of artificial intelligence is also valuable in gastrointestinal diseases,by calculating various scoring systems,evaluating radiological images,preoperative and intraoperative assistance,processing pathological slides,prognosticating,and in treatment responses.This field has a promising future and can have an impact on many management algorithms.In this minireview,we aimed to determine the basics of artificial intelligence,the role that artificial intelligence may play in gastrointestinal surgeries and malignancies,and the limitations thereof.

Safety of fast-track rehabilitation after gastrointestinal surgery:Systematic review and meta-analysis

Gastrointestinal metabolic surgery for the treatment of type 2 diabetes mellitus

Medical therapy for type 2 diabetes mellitus is ineffective in the long term due to the progressive nature of the disease, which requires increasing medication doses and polypharmacy. Conversely, bariatric surgery has emerged as a cost-effective strategy for obese diabetic individuals; it has low complication rates and results in durable weight loss, glycemic control and improvements in the quality of life, obesity-related co-morbidity and overall survival. The finding that glucose homeostasis can be achieved with a weight loss-independent mechanism immediately after bariatric surgery, especially gastric bypass, has led to the paradigm of metabolic surgery. However, the primary focus of metabolic surgery is the alteration of the physio-anatomy of the gastrointestinal tract to achieve glycemic control, metabolic control and cardio-metabolic risk reduction. To date, metabolic surgery is still not well defined, as it is used most frequently for less obese patients with poorly controlled diabetes. The mechanism of glycemic control is still incompletely understood. Published research findings on metabolic surgery are promising, but many aspects still need to be defined. This paper examines the proposed mechanism of diabetes remission, the efficacy of different types of metabolic procedures, the durability of glucose control, and the risks and complications associated with this procedure. We propose a tailored approach for the selection of the ideal metabolic procedure for different groups of patients, considering the indications and prognostic factors for diabetes remission.

Peritoneal adhesions after laparoscopic gastrointestinal surgery

Although laparoscopy has the potential to reduce peritoneal trauma and post-operative peritoneal adhesion formation, only one randomized controlled trial and a few comparative retrospective clinical studies have addressed this issue. Laparoscopy reduces de novo adhesion formation but has no efficacy in reducing adhesion reformation after adhesiolysis. Moreover, several studies have suggested that the reduction of de novo post-operative adhesions does not seem to have a significant clinical impact. Experimental data in animal models have suggested that CO2 pneumoperitoneum can cause acute peritoneal inflammation during laparoscopy depending on the insufflation pressure and the surgery duration. Broad peritoneal cavity protection by the insufflation of a low-temperature humidified gas mixture of CO2, N2O and O2 seems to represent the best approach for reducing peritoneal inflammation due to pneumoperitoneum. However, these experimental data have not had a significant impact on the modification of laparoscopic instrumentation. In contrast, surgeons should train themselves to perform laparoscopy quickly, and they should complete their learning curves before testing chemical anti-adhesive agents and anti-adhesion barriers. Chemical anti-adhesive agents have the potential to exert broad peritoneal cavity protection against adhesion formation, but when these agents are used alone, the concentrations needed to prevent adhesions are too high and could cause major post-operative side effects. Anti-adhesion barriers have been used mainly in open surgery, but some clinical data from laparoscopic surgeries are already available. Sprays, gels, and fluid barriers are easier to apply in laparoscopic surgery than solid barriers. Results have been encouraging with solid barriers, spray barriers, and gel barriers, but they have been ambiguous with fluid barriers. Moreover, when barriers have been used alone, the maximum protection against adhesion formation has been no greater than 60%. A recent small, randomized clinical trial suggested that the combination of broad peritoneal cavity protection with local application of a barrier could be almost 100% effective in preventing post-operative adhesion formation. Future studies should confirm the efficacy of this global strategy in preventing adhesion formation after laparoscopy by focusing on clinical end points, such as reduced incidences of bowel obstruction and abdominal pain and increased fertility.

Laparoscopic approach in gastrointestinal emergencies

This review focuses on the laparoscopic approach to gastrointestinal emergencies and its more recent indications. Laparoscopic surgery has a specific place in elective procedures, but that does not apply in emergency situations. In specific emergencies, there is a huge range of indications and different techniques to apply, and not all of them are equally settle. We consider that the most controversial points in minimally invasive procedures are indications in emergency situations due to technical difficulties. Some pathologies, such as oesophageal emergencies, obstruction due to colon cancer, abdominal hernias or incarcerated postsurgical hernias, are nearly always resolved by conventional surgery, that is, an open approach due to limited intraabdominal cavity space or due to the vulnerability of the bowel. These technical problems have been solved in many diseases, such as for perforated peptic ulcer or acute appendectomy for which a laparoscopic approach has become a wellknown and globally supported procedure. On the other hand, endoscopic procedures have acquired further indications, relegating surgical solutions to a second place; this happens in cholangitis or pancreatic abscess drainage. This endoluminal approach avoids the need for laparoscopic development in these diseases. Nevertheless, new instruments and new technologies could extend the laparoscopic approach to a broader array of potentials procedures. There remains, however, a long way to go.

Extracellular matrices for gastrointestinal surgery:Ex vivo testing and current applications

AIM:To assess the effects of bile and pancreatic juice on structural and mechanical resistance of extracellular matrices(ECMs) in vitro.METHODS:Small-intestinal submucosa(SIS),porcine dermal matrix(PDM),porcine pericardial matrix(PPM) and bovine pericardial matrix(BPM) were incubated in human bile and pancreatic juice in vitro.ECMs were examined by macroscopic observation,scanning electron microscopy(SEM) and testing of mechanical resistance.RESULTS:PDM dissolved within 4 d after exposure to bile or pancreatic juice.SIS,PPM and PDM retained their integrity for > 60 d when incubated in either digestive juice.The effect of bile was found to be far more detrimental to mechanical stability than pancreatic juice in all tested materials.In SIS,the loss of mechanical stability after incubation in either of the digestive secretions was less distinct than in PPM and BPM [mFmax 4.01/14.27 N(SIS) vs 2.08/5.23 N(PPM) vs 1.48/7.89 N(BPM)].In SIS,the extent of structural damage revealed by SEM was more evident in bile than in pancreatic juice.In PPM and BPM,structural damage was comparable in both media.CONCLUSION:PDM is less suitable for support of gastrointestinal healing.Besides SIS,PPM and BPM should also be evaluated experimentally for gastrointestinal indications.

Neutrophil-to-lymphocyte ratio predicts acute kidney injury occurrence after gastrointestinal and hepatobiliary surgery

BACKGROUND Postoperative acute kidney injury(AKI) is a complex pathological process involved intrarenal and systemic inflammation caused by renal hypoperfusion, nephrotoxic drugs and urinary obstruction. Neutrophil-to-lymphocyte ratio(NLR) is a marker of inflammation reflecting the progress of many diseases. However, whether NLR at admission can predict the occurrence of AKI after surgery in the intensive care unit(ICU) remains unknown.AIM To clarify the relationship between NLR and the occurrence of AKI in patients with gastrointestinal and hepatobiliary surgery in the ICU.METHODS A retrospective analysis of 282 patients receiving surgical ICU care after gastrointestinal and hepatobiliary surgery in our hospital from December 2014 to December 2018 was performed.RESULTS Postoperative AKI occurred in 84 patients(29.79%) in this cohort. NLR by the multivariate analysis was an independent risk factor for occurrence of postoperative AKI in patients with gastrointestinal and hepatobiliary surgery in the ICU. In this cohort, receiver operating characteristic curves of AKI occurrence showed that the optimal cut-off value of NLR was 8.380. NLR was found to be significantly correlated with the white blood cell count, neutrophil count, lymphocyte count, arterial lactate and dialysis(P < 0.05). Additionally, NLR value at admission was higher in AKI patients compared with the non-AKI patients and increased with the severity of AKI. Patients with NLR ≥ 8.380 exhibited significantly higher incidences of postoperative AKI and severe AKI than patients with NLR < 8.380(AKI: 38.12% vs 14.85%, P < 0.001;severe AKI: 14.36% vs 1.98%, P = 0.001).CONCLUSION NLR at admission is a predictor of AKI occurrence in patients with gastrointestinal and hepatobiliary surgery in ICU. NLR should be included in the routine assessment of AKI occurrence.

Gastrointestinal obstruction secondary to enteral nutrition bezoar: A case report

BACKGROUND Post-operative enteral nutrition via gastric or jejunal feeding tubes is a common and standard practice in managing the critically ill or post-surgical patient.It has its own set of complications,including obstruction,abscess formation,necrosis,and pancreatitis.We present here a case of small bowel obstruction caused by enteral nutrition bezoar.It is the second recorded incidence of this complication after pancreaticoduodenectomy in the medical literature.CASE SUMMARY The 70-year-old female presented to our institution for a pancreaticoduodenectomy(Whipple’s procedure)for pancreatic adenocarcinoma.On day 5 post-operative,having failed to progress and developing symptoms of small bowel obstruction,she underwent a computed tomography scan,which showed features of mechanical small bowel obstruction.Following this,she underwent an emergency laparotomy and small bowel decompression.The recovery was long and protracted but,ultimately,she was discharged home.A literature search of reports from 1966-2020 was conducted in the MEDLINE database.We identified eight articles describing a total of 14 cases of small bowel obstruction secondary to enteral feed bezoar.Of those 14 cases,all but 4 occurred after upper gastrointestinal surgery;all but 1 case required further surgical intervention for deteriorating clinical picture.The postulated causes for this include pH changes,a reduction in pancreatic enzymes and gastric motility,and the use of opioid medication.CONCLUSION Enteral feed bezoar is a complication of enteral feeding.Despite rare incidence,it can cause significant morbidity and potential mortality.

Indocyanine green dye and its application in gastrointestinal surgery:The future is bright green

Indocyanine green(ICG)is a water-soluble fluorescent dye that is minimally toxic and widely used in gastrointestinal surgery.ICG facilitates anatomical identi-fication of structures(e.g.,ureters),assessment of lymph nodes,biliary mapping,organ perfusion and anastomosis assessment,and aids in determining the adequacy of oncological margins.In addition,ICG can be conjugated to artificially created antibodies for tumour markers,such as carcinoembryonic antigen for colorectal,breast,lung,and gastric cancer,prostate-specific antigen for prostate cancer,and cancer antigen 125 for ovarian cancer.Although ICG has shown promising results,the optimization of patient factors,dye factors,equipment,and the method of assessing fluorescence intensity could further enhance its utility.This review summarizes the clinical application of ICG in gastrointestinal surgery and discusses the emergence of novel dyes such as ZW-800 and VM678 that have demonstrated appropriate pharmacokinetic properties and improved target-to-background ratios in animal studies.With the emergence of robotic technology and the increasing reporting of ICG utility,a comprehensive review of clinical application of ICG in gastrointestinal surgery is timely and this review serves that aim.

Bacterial translocation in patients undergoing major gastrointestinal surgery and its role in postoperative sepsis

Bacteria of the human intestinal microflora have a dual role.They promote digestion and are part of a defense mechanism against pathogens.These bacteria could become potential pathogens under certain circumstances.The term“bacterial translocation”describes the passage of bacteria of the gastrointestinal tract through the intestinal mucosa barrier to mesenteric lymph nodes and other organs.In some cases,the passage of bacteria and endotoxins could result in blood stream infections and in multiple organ failure.Open elective abdominal surgery more frequently results in malfunction of the intestinal barrier and subsequent bacterial translocation and blood stream infections than laparoscopic surgery.Postoperative sepsis is a common finding in patients who have undergone non-elective abdominal surgeries,including trauma patients treated with laparotomy.Postoperative sepsis is an emerging issue,as it changes the treatment plan in surgical patients and prolongs hospital stay.The association between bacterial translocation and postoperative sepsis could provide novel treatment options.

Paradigm shift in gastrointestinal surgery−combating sarcopenia with prehabilitation:Multimodal review of clinical and scientific data

A growing body of evidence has demonstrated the prognostic significance of sarcopenia in surgical patients as an independent predictor of postoperative complications and outcomes.These included an increased risk of total complications,major complications,re-admissions,infections,severe infections,30 d mortality,longer hospital stay and increased hospitalization expenditures.A program to enhance recovery after surgery was meant to address these complications;however,compliance to the program since its introduction has been less than ideal.Over the last decade,the concept of prehabilitation,or"pre-surgery rehabilitation",has been discussed.The presurgical period represents a window of opportunity to boost and optimize the health of an individual,providing a compensatory"buffer"for the imminent reduction in physiological reserve postsurgery.Initial results have been promising.We review the literature to critically review the utility of prehabilitation,not just in the clinical realm,but also in the scientific realm,with a resource management point-of-view.

Effects of an Omaha System-based follow-up regimen on self-care and quality of life in gastrointestinal surgery patients

BACKGROUND Currently,a variety of new nursing methods and routine nursing have been widely used in the nursing of gastrointestinal surgery patients.AIM To investigate the effect of follow-up protocol based on the Omaha System on self-care ability and quality of life of gastrointestinal surgery patients.METHODS A total of 128 patients with inflammatory bowel disease in gastrointestinal surgery in gastrointestinal surgery from March 2019 to August 2021 were divided into A(n=64)and B(n=64)groups according to different nursing methods.The group A received a follow-up program Omaha System-based intervention of the group B,whereas the group B received the routine nursing intervention.Medical Coping Modes Questionnaire,Crohn’s and Colitis Knowledge Score(CCKNOW),inflammatory bowel disease questionnaire(IBDQ),Exercise of Self-nursing Agency Scale(ESCA),The Modified Mayo Endoscopic Score,and Beliefs about Medicine Questionnaire(BMQ)were compared between the two groups.RESULTS Following the intervention,the group A were facing score significantly increased than group B,while the avoidance and yield scores dropped below of group B(all P<0.05);in group A,the level of health knowledge,personal care abilities,self-perception,self-awareness score and ESCA total score were more outstanding than group B(all P<0.05);in group A the frequency of defecation,hematochezia,endoscopic performance,the total evaluation score by physicians and the disease activity were lower than group B(all P<0.05);in the group A,the total scores of knowledge in general,diet,drug,and complication and CCKNOW were higher than group B(all P<0.05);in group A,the necessity of taking medicine,score of medicine concern and over-all score of BMQ were more significant than group B(all P<0.05);at last in the group A,the scores of systemic and intestinal symptoms,social and emotional function,and IBDQ in the group A were higher than group B(all P<0.05).CONCLUSION For gastrointestinal surgery patients,the Omaha System-based sequel protocol can improve disease awareness and intervention compliance,help them to face the disease positively,reduce disease activity,and improve patients’self-nursing ability and quality of life.
