Intestinal Dialysis Research Progress and the Early Treatment of a NonDiabetic Patient with Symptomatic Uremia and Fatty Liver with Intestinal Dialysis: The Practice of Evidence-Based Medicine

Background: Chronic renal failure results from a variety of pathophysiological mechanisms and etiologies, and is associated with progressive and irreversible damage and loss of the kidneys’ tissue leading to failure of the kidneys to excrete waste products, and also failure to perform some other functions. Many patients with chronic renal failure in a country like Iraq has been reported to be reluctant to accept dialysis therapies because of the wide spread notion of its association with high mortality. The lack of effective, convenient, and affordable therapy for chronic renal failure in many regions of the world should not mean should that the patients with advanced chronic renal failure are left without other suitable, convenient and acceptable care. The aim of this paper is to describe the early treatment of a patient with symptomatic uremia with intestinal dialysis. Patients and Methods: A 60-year non-diabetic male patient was experiencing progressive symptomatic uremia. On the 18th of November, 2023, blood urea was elevated at 217 mg/dL, serum creatine was 5.2 mg/dL, and he had symptomatic uremia with nausea, vomiting, fatigue, pruritus and anemia. The patient was treated with intestinal dialysis (Acacia gum supplementation plus conservative dietary and pharmacological management of chronic renal failure) which was prescribed according to the latest published guidelines. It was necessary during the first week of treatment to eliminate almost all dietary protein, and his diet was consisting mainly of high calorie juices, grapes, and water melon. Results: When the patient was seen on the 2nd of December, 2023, treatment was associated with marked symptomatic and laboratory improvements. Blood urea was 115 mg /dL, serum creatine was 3.6 mg /dL However, and serum calcium was 5.3 mg/dL (Normal ranges: 8-10.5 mg/dL). Therefore, oral alphacalcidol was added in a dose of 1 microgram daily. Conclusion: Intestinal dialysis will continue to be used to improve the management of chronic renal failure and symptomatic uremia as long as there is no convenient and affordable therapy for chronic renal failure in many regions of the world.

Comparing and Analyzing the Physical and Functional Concerns of Post Breast Cancer Surgery Patients Who Received Physical Therapy for Lymphedema After Surgery to Those Who Did Not Receive Physical Therapy After Surgery

Objective: This pilot research project examined the physical and functional concerns of patients who had breast cancer surgery followed by receiving skilled physical therapy or lymphedema therapy services for more than or less than three months. Methods: This research study utilized the Qualtrics system to create a survey for the participants to complete. After completing the survey, the researchers divided the participants into two groups. The researchers analyzed the data using SPSS to run independent sample t-tests. Results: The study results show no significant difference in limb size and self-care activities between the two groups who received physical therapy.

The impact of anastomotic leakage on the quality of life of patients after surgery for rectal cancer

AIM: to assess the impact of colorectal anastomotic leakage on the severity of low anterior rectal resection syndrome and the quality of life.PATIENTS AND METHODS: the results of 375 patients with rectal tumors were analyzed. In 26 patients, surgery was complicated by anastomosis failure. For a assessment of the quality of life of patients with anastomotic leakage, each patient was matched with a pair from the group of respondents with an uncomplicated postoperative period. The quality of life was assessed in all patients using the EORTC QLQ-C30 questionnaire with the Cr-29 module.RESULTS: patients with anastomosis leakage have more severe low anterior rectal resection syndrome — 29 (17;34), versus 20 (9;28) points (p = 0.03) and a lower global score (p = 0.01), physical (p = 0.01) and social (p = 0.04) functioning. The symptom scales of the EORTC QLQ-C30 questionnaire, supplemented by the Cr-29 module, had significant differences between groups on the scales of body image (p = 0.01), fecal incontinence (p = 0.04) and embarrassment (p = 0.01).CONCLUSION: colorectal anastomosis leakage negatively affects the quality of life of patients.

Evaluation of the First Approach Skills Training (FAST) Integrated Pediatric Primary Care Program: Implementation and Clinical Effectiveness

ABSTRACT The current study evaluated the clinical effectiveness and implementation of a brief integrated pediatric primary care program, First Approach Skills Training (FAST). We analyzed clinical retrospective data during the first year of implementation of FAST. Patients and parents completed symptom measures as part of standard clinical care. Integrated behavioral health providers completed measures regarding the FAST program's usability, feasibility, effectiveness, and cultural responsiveness. Patients and parents reported significant improvement in anxiety symptoms, depression symptoms, and disruptive behaviors. Clinicians rated FAST as highly usable, feasible, effective, and culturally responsive. The FAST program demonstrates preliminary clinical effectiveness for common youth mental health problems in pediatric primary care.

Paediatric pulmonary hypertension due to congenital heart disease in non-cardiac surgery: Anaesthetic implications

Paediatric patients with pulmonary hypertension associated with Congenital Heart Disease (PH-CHD) are frequently encountered in non-cardiac surgical settings. Although the pharmacological and surgical management of the underlying CHD in the group has improved yet its management remains challenging due to associated high morbidity and mortality. The dilemma prevails more so because of the dearth of adequate literature describing its pathophysiology and management in non-cardiac surgical settings. There are no specific guidelines pertaining to paediatric PH-CHD care, and the precepts have been extrapolated from adult studies and guidelines. This review article intends to apprise the pathophysiology of PH-CHD, its management, and its perioperative care with special emphasis on pulmonary vascular hypertensive crisis in these patients posted for non-cardiac procedures.

Kidney-sparing surgery has equivalent oncological outcomes to radical nephroureterectomy for ureteral urothelial carcinoma.

Kidney-sparing surgery (KSS) for upper tract urothelial cancer (UTUC) has gained increasing interest recently. However, there is limited contemporary data regarding the role of KSS in ureteral urothelial carcinoma. Therefore, we investigated the survival outcomes of ureteral urothelial carcinoma after KSS from a large prospective international UTUC registry. The Clinical Research Office of the Endourology Society-Urothelial Carcinomas of the Upper Tract (CROES-UTUC) Registry included UTUC patients who received KSS or radical nephroureterectomy (RNU) between 2014 and 2019. In this study, we included patients with ureteral UTUC only. Study outcomes included overall survival (OS), cancer-specific survival (CSS), upper tract recurrence-free survival (RFS), intravesical RFS, progression-free survival (PFS), and metastasis-free survival (MFS). Propensity score matching (PSM) was performed to balance the tumour features' differences between groups. Of 391 patients with ureteral UTUC, 309 (79.0%) received RNU, and 82 (21.0%) received KSS by ureteroscopy with laser ablation (n=28) or segmental resection (n=54). After PSM, there were no differences in OS (p=0.525), CSS (p=0.487), upper tract RFS (p=0.147), intravesical RFS (p=0.989), PFS (p=0.617), and MFS (p=0.336) between KSS and RNU. Both ureteroscopic ablation and segmental resection had similar OS, CSS, intravesical RFS, PFS, and MFS with RNU. Proximal ureteral UTUC had worse OS and CSS outcomes than other tumour locations following segmental resection. In patients with ureteral UTUC, no significant differences in long-term survival outcomes were observed between KSS and RNU. Proximal ureteral UTUC had worse survival outcomes over other tumour locations following segmental resection.

Advances in Point-of-Care Ultrasound in Pediatric Acute Care Medicine.

Pediatric point-of-care ultrasonography (POCUS) has grown in utilization and is now an integral part of pediatric acute care. Applications within the pediatric critical care, neonatology and pediatric emergency were once limited to evaluation of undifferentiated shock states, abdominal free fluid assessments in trauma resuscitation and procedural guidance. The body of pediatric POCUS literature is ever expanding and recently published international consensus guidelines are available to guide implementation into clinical practice. The authors present a review of emerging applications and controversies within thoracic, hemodynamic, neurologic, and ocular POCUS in pediatric acute care medicine.

Pediatric Pharmacology for the Primary Care Provider: Advances and Limitations.

Despite >1 in 5 children taking prescription drugs in the United States, off-label drug use is common. To increase the study of drugs in children, regulatory bodies have enacted legislation to incentivize and require pediatric drug studies. As a result of this legislation, novel trial approaches, and an increase in personnel with pediatric expertise, there have been numerous advancements in pediatric drug development. With this review, we aim to highlight developments in pediatric pharmacology over the past 6 years for the most common disease processes that may be treated pharmacologically by the pediatric primary care provider. Using information extracted from label changes between 2018 and 2023, the published literature, and Clinicaltrials.gov, we discuss advances across multiple therapeutic areas relevant to the pediatric primary care provider, including asthma, obesity and related disorders, mental health disorders, infections, and dermatologic conditions. We highlight instances in which new drugs have been developed on the basis of a deeper mechanistic understanding of illness and instances in which labels have been expanded in older drugs on the basis of newly available data. We then consider additional factors that affect pediatric drug use, including cost and nonpharmacologic therapies. Although there is work to be done, efforts focused on pediatric-specific drug development will increase the availability of evidence-based, labeled guidance for commonly prescribed drugs and improve outcomes through the safe and effective use of drugs in children.

Development of a plant-based surgical training model for fluorescence-guided cancer surgery.

Fluorescence-guided surgery (FGS) can help surgeons to discriminate tumor tissue from adjacent normal tissues using fluorescent tracers. We developed a surgical training model, manufactured using sustainable vegetable organic material with indocyanine green (ICG)-containing "tumor." Surgeons evaluated the model with both the closed-field and endoscopic fluorescence imaging devices and assessed its efficacy to identify residual tumor after enucleation using electrocautery. Strong correlations of fluorescence were obtained at all working distance (3, 5, 7, and 10 cm), showing the robustness of fluorescence signal for the closed-field and endoscopic fluorescence imaging devices. The higher fluorescence signals were obtained in the wound bed in the closed-field fluorescence imaging device and the residual tumor could be clearly identified by fluorescence endoscopy. Our FGS training model may provide experience for surgeons unfamiliar with optical surgery and subsequent tissue interactions. The model seemed particularly helpful in teaching surgeons the principles of FGS.

Dynamic Covalent Chemistry of Enamine-ones: Exploring Tunable Reactivity in Vitrimeric Polymers and Covalent Organic Frameworks.

Dynamic covalent chemistry (DCC) has revolutionized the field of polymer science by offering new opportunities for the synthesis, processability, and recyclability of polymers as well as in the development of new materials with interesting properties such as vitrimers and covalent organic frameworks (COFs). Many DCC linkages have been explored for this purpose, but recently, enamine-ones have proven to be promising dynamic linkages because of their facile reversible transamination reactions under thermodynamic control. Their high stability, stimuli-responsive properties, and tunable kinetics make them promising dynamic cross-linkers in network polymers. Given the rapid developments in the field in recent years, this review provides a critical and up-to-date overview of recent developments in enamine-one chemistry, including factors that control their dynamics. The focus of the review will be on the utility of enamine-ones in designing a variety of processable and self-healable polymers with important applications in vitrimers and recyclable closed-loop polymers. The use of enamine-one linkages in crystalline polymers, known as COFs and their applications are also summarized. Finally, we provide an outlook for future developments in this field.

An Age-Stratified Analysis of Early Postoperative Mortality Among Medicare-Eligible Patients With Common Gastrointestinal and Hepato-pancreato-biliary Malignancies.

Background: The frequency of major cancer surgery in the elderly (≥80years) has increased concomitantly with the rise in average age of the population. We assessed early postoperative mortality following hepato-pancreato-biliary (HPB) and gastrointestinal (GI) procedures for common malignancies stratified by age. Methods: The National Cancer Database (2004-2017) was queried for patients who underwent resection for GI (gastroesophageal and colorectal) or HPB (pancreatic adenocarcinoma, biliary tract, and primary liver) cancers. We compared early postoperative mortality (30d and 90d) stratified by age (65-79 vs ≥80years) and procedure, and compared survival outcomes by age and operative vs nonoperative management. Results: A total of 709,358 patients were included. The 30-day mortality ranged from 1.8% to 5.8% among patients 65-79years and from 3.2% to 12.4% among patients ≥80years depending on procedure. The 90-day mortality ranged from 3.6% to 10.6% in patients 65-79years compared to 8.4%-21.0% among patients ≥80years. The overall 90-day mortality was 5.2% for patients 65-79years and 12.0% for patients ≥80years (P < .001). Age ≥80 was associated with worse survival among operatively managed patients with each upper GI, HPB, and lower GI malignancy relative to younger patients on multivariable analysis. However, operative management of patients ≥80years was associated with improved survival relative to nonoperative management. Discussion: Elderly patients suffer higher postoperative mortality after major GI and HPB cancer surgery, but operative management is associated with improved survival among patients ≥80years as compared to nonoperative management. These data are important to contextualize when counseling elderly patients on their treatment options for localized GI and HPB cancers.

Palliative care progress in Benin: a situation analysis using the WHO development indicators

ContextPalliative care (PC) in most African countries remains under-assessed. Benin has piloted the implementation of a set of indicators proposed by the WHO to measure PC development.ObjectivesTo examine the current status of PC in Benin.MethodsA workshop with stakeholders was organized to assess the WHO indicators in the Beninese context. Indicators were rated based on relevance and feasibility, data sources were agreed upon, and a survey was adapted. Data were collected between March and May 2023.ResultsThere is emerging community involvement in PC through the presence of patients’ rights promoters, as well as a political commitment expressed in the National PC strategy, the inclusion of PC services in the list of basic health services, and an assigned national authority –within the Ministry of Health–responsible for PC. Although no PC-oriented research has been documented, the celebration of the National PC Conference represents the first step to ground PC delivery in evidence. The reported annual consumption of opioids is 0.18 (ME) milligrams per capita, 34% of healthcare establishments have essential medicines for pain and PC, and 16.5% of patients with palliative needs have access to oral morphine. To date, no medical or paramedical schools offer PC training, and there is no official specialization in palliative medicine for doctors. PC is provided by 11 specialist teams (0.08/100,000 inhabitants), none of which provides pediatric care.ConclusionDespite growing political, professional, and community commitments to palliative care, there are challenges in education, research, essential medicines, and access to PC services.

Successful R0 resection after chemotherapy, including nivolumab, for gastric cancer with liver metastases: three case reports

BackgroundAdvances in chemotherapy have increased clinical experience with conversion surgery for inoperable advanced gastric cancer. This report describes three patients with unresectable gastric cancer accompanied by multiple liver metastases. In all three patients, nivolumab resolved the liver metastases and subsequent conversion surgery achieved a pathological complete response.Case presentationIn Case 1, a 68-year-old man with clinical Stage IVB gastric cancer and multiple liver metastases initiated first-line therapy with SOX plus nivolumab. The patient completed 13 cycles; however, only nivolumab was continued for 3 cycles because of adverse events. Distal gastrectomy and partial hepatic resection were performed because of a significant reduction in the size of the liver metastases as observed on magnetic resonance imaging (MRI). In Case 2, a 72-year-old man with clinical Stage IVB gastric cancer and multiple liver metastases initiated first-line therapy with SOX. Because of the subsequent emergence of new liver metastases, the patient transitioned to ramucirumab plus paclitaxel as second-line therapy. Third-line therapy with nivolumab was initiated because of side effects. MRI revealed necrosis within the liver metastasis, and the patient underwent proximal gastrectomy and partial hepatectomy. In Case 3, a 51-year-old woman with clinical Stage IVB gastric cancer accompanied by multiple metastases of the liver and para-aortic lymph nodes began first-line therapy with SOX plus nivolumab. The patient completed 10 cycles; however, only nivolumab was continued for 5 cycles because of adverse events. Computed tomography showed a significant decrease in the size of the para-aortic lymph nodes, while MRI indicated the presence of a singular liver metastasis. Distal gastrectomy and partial hepatic resection were subsequently performed. In all three cases, MRI revealed the presence of liver metastases; however, pathological examination showed no viable tumor cells.ConclusionsWe herein present three cases in which chemotherapy, including nivolumab, elicited a response in patients with multiple unresectable liver metastases, ultimately culminating in R0 resection through conversion surgery. Although MRI showed liver metastases, pathological analysis revealed no cancer, underscoring the beneficial impact of chemotherapy.

Potential Survival Benefit of Upfront Surgery for Lung Tumors Unconfirmed but Highly Suspicious for Stage I Lung Cancer.

Patients with early-stage lung tumors that are highly suspicious for malignancy typically undergo a preoperative diagnostic workup, primarily through bronchoscopy or transthoracic biopsy. Those without a preoperative diagnosis may alternatively be treated with upfront surgery, contingent upon the potential for intraoperative diagnosis. Previous studies have yielded conflicting results regarding the impact of upfront surgery on the survival of these patients. Our study aimed to elucidate the effect of upfront surgery on the survival outcomes of patients undergoing surgery for early-stage lung cancer without a preoperative diagnosis. We analyzed the survival rate of 158 consecutive patients who underwent pulmonary resection for stage I lung cancer, either with or without a preoperative diagnosis. A total of 86 patients (54%) underwent upfront surgery. This approach positively impacted both disease-free survival (p=0.031) and overall survival (p=0.017). However, no significant differences were observed across subgroups based on sex, smoking status, forced expiratory volume in 1 second, histologic tumor size, or histologic subtype. Univariate analysis identified upfront surgery (p=0.020), age (p=0.002), maximum standardized uptake value (SUVmax) exceeding 7 (p=0.001), and histological tumor size greater than 20 mm (p=0.009) as independent predictors. However, multivariate analysis indicated that only SUVmax greater than 7 (p=0.011) was a significant predictor of unfavorable survival. Upfront surgery does not appear to confer a survival advantage in patients with stage I lung cancer undergoing surgical intervention.

The impact of previous abdominal surgery on colorectal cancer patients undergoing laparoscopic surgery.

The current study aimed to investigate whether previous abdominal surgery (PAS) could affect the outcomes of colorectal cancer (CRC) surgery. We conducted the search strategy in three databases (PubMed, Embase, and the Cochrane Library) from inception to May 26, 2022. The short-term and long-term outcomes were compared between the PAS group and the non-PAS group. Odds ratios (ORs) and 95% confidence intervals (CIs) were pooled up. Stata (V.16.0) software was used for data analysis. We included 34,827 patients from 14 studies in the current study. After pooling up all the data, we found that there were higher proportions of overall complications (OR = 1.12, I2 = 4.65%, 95% CI 1.03 to 1.23, P = 0.01), ileus (OR = 1.96, I2 = 59.74%, 95% CI 1.12 to 3.44, P = 0.02) and mortality (OR = 1.26, I2 = 0.00%, 95% CI 1.11 to 1.42, P = 0.00) in the PAS group than the non-PAS group. Patients with a history of PAS had higher risks of overall complications and death following CRC surgery. However, it did not appear to significantly affect the short-term outcomes apart from ileus. Surgeons should raise awareness of patients with a history of PAS, and take steps to reduce postoperative complications and mortality.

Accelerating Innovation in Primary Care to Support Adolescent Health Discussions.

Adolescent strengths and risks are not routinely captured in systematized and actionable ways in pediatric primary care. To address this problem, we developed a comprehensive adolescent health questionnaire (AHQ) integrated within the electronic health record and evaluated the AHQ's impact on collection of information on prioritized health-related domains. We developed and pilot tested the AHQ. We then scaled and assessed the AHQ's impact on data collection. AHQ development used innovation methods and measured feasibility and acceptability outcomes. Scaling and postscaling outcomes included Reach, Effectiveness, Adoption, Implementation, Maintenance and Sustainability measures: Reach (total questionnaires completed), Effectiveness (capture of key information across health domains pre- vs post-AHQ scaling), Adoption (proportion of practices that adopted the AHQ), Implementation (proportion of eligible adolescents who completed the AHQ), and Maintenance (monthly completion rates). AHQ development led to a tool that was feasible and acceptable for use. During scaling (October 2020-December 2021), 22 147 questionnaires were completed by 20 749 unique adolescents aged 13 to 21 years at their preventive visit. Comparing pre- versus post-AHQ scaling data, use of the AHQ increased collection of information across domains, especially for strengths, gun safety, substance use, sexual activity, sexual orientation, and gender identity, from ranges of 0%-25% to 92%-95%. All 31 practices adopted the AHQ with completion at 88.7% of visits (n = 24 968). Two years postscaling, completion rates were >91% per month. We successfully developed, scaled, and maintained an AHQ in a widely-used electronic health record system, a model for improving adolescent care and foundation for developing future interventions.

Transient stabilization of human cardiovascular progenitor cells from hPSCs in vitro reflects stage-specific heart development in vivo.

Understanding the molecular identity of human pluripotent stem cell (hPSC)-derived cardiac progenitors and mechanisms controlling their proliferation and differentiation, is valuable for developmental biology and regenerative medicine. Here we show that chemical modulation of Histone Acetyl Transferases (HATs; by IQ-1) and WNT (by CHIR99021), synergistically enable the transient and reversible block of directed cardiac differentiation progression on hPSCs. The resulting stabilized cardiovascular progenitors (SCPs) are characterized by ISL1pos/KI-67pos/NKX2-5neg expression. In the presence of the chemical inhibitors, SCPs maintain a proliferation quiescent state. Upon small molecules removal SCPs resume proliferation and concomitant NKX2-5 upregulation triggers cell-autonomous differentiation into cardiomyocytes. Directed differentiation of SCPs into the endothelial and smooth muscle lineages confirms their full developmental potential typical of bona fide cardiovascular progenitors. Single-cell RNAseq-based transcriptional profiling of our in vitro generated human SCPs notably reflects the dynamic cellular composition of E8.25-E9.25 posterior second heart field (pSHF) of mouse hearts, hallmarked by NR2F2 expression. Investigating molecular mechanisms of SCP stabilization, we found that the cell-autonomously regulated Retinoic Acid (RA) and BMP signaling is governing SCPs transition from quiescence towards proliferation and cell-autonomous differentiation, reminiscent of a niche-like behavior. The chemically defined and reversible nature our stabilization approach provides an unprecedented opportunity to dissect mechanisms of cardiovascular progenitors' specification and reveal their cellular and molecular properties.

Undercounting diagnoses in Australian general practice: a data quality study with implications for population health reporting

BackgroundDiagnosis can often be recorded in electronic medical records (EMRs) as free-text or using a term with a diagnosis code. Researchers, governments, and agencies, including organisations that deliver incentivised primary care quality improvement programs, frequently utilise coded data only and often ignore free-text entries. Diagnosis data are reported for population healthcare planning including resource allocation for patient care. This study sought to determine if diagnosis counts based on coded diagnosis data only, led to under-reporting of disease prevalence and if so, to what extent for six common or important chronic diseases.MethodsThis cross-sectional data quality study used de-identified EMR data from 84 general practices in Victoria, Australia. Data represented 456,125 patients who attended one of the general practices three or more times in two years between January 2021 and December 2022. We reviewed the percentage and proportional difference between patient counts of coded diagnosis entries alone and patient counts of clinically validated free-text entries for asthma, chronic kidney disease, chronic obstructive pulmonary disease, dementia, type 1 diabetes and type 2 diabetes.ResultsUndercounts were evident in all six diagnoses when using coded diagnoses alone (2.57–36.72% undercount), of these, five were statistically significant. Overall, 26.4% of all patient diagnoses had not been coded. There was high variation between practices in recording of coded diagnoses, but coding for type 2 diabetes was well captured by most practices.ConclusionIn Australia clinical decision support and the reporting of aggregated patient diagnosis data to government that relies on coded diagnoses can lead to significant underreporting of diagnoses compared to counts that also incorporate clinically validated free-text diagnoses. Diagnosis underreporting can impact on population health, healthcare planning, resource allocation, and patient care. We propose the use of phenotypes derived from clinically validated text entries to enhance the accuracy of diagnosis and disease reporting. There are existing technologies and collaborations from which to build trusted mechanisms to provide greater reliability of general practice EMR data used for secondary purposes.

Multicenter prospective study on anastomotic leakage after right‐sided colon cancer surgery with laparoscopic intracorporeal overlap anastomosis (KYCC 2101)

AbstractAimIntracorporeal anastomosis (IA) is becoming increasingly popular and replacing extracorporeal anastomosis (EA) for reconstruction in laparoscopic and robotic surgery for right‐sided colon cancer (LSRCC). Intracorporeal overlap anastomosis (IOA) is the most widely used IA technique. This study aimed to examine the safety of IOA by investigating its short‐term results during the implementation phase.MethodsThis multicenter prospective cohort study was conducted by the Kanagawa Yokohama Colorectal Cancer (KYCC) Study Group. Patients with stage 1–3 colon cancer who planned to undergo LSRCC with IOA reconstruction were eligible. The incidence of anastomotic leakage (AL) of Clavien–Dindo (C–D) grade ≥3 was evaluated as the primary endpoint, and other surgical outcomes and postoperative complications of C–D grades ≥2 were the secondary endpoints.ResultsA total of 127 patients were enrolled, of whom 120 were finally analyzed. The incidence of C–D grade ≥2 complications was 8.3%. The incidence of C–D grade ≥3 AL was 0.8%. This trend was lower than that reported in previous randomized controlled trials (RCTs) and acceptable. Additionally, 1.7% of the patients developed abdominal abscesses, and no cases of anastomotic stenosis were observed. The median operative time was 257 min, and the reconstruction procedure required 32 min. Stapler closure of the enterotomy and facility experience of more than 30 cases were associated with a shorter reconstruction time during IOA.ConclusionIOA is feasible and can be safely performed during the implementation phase in patients undergoing LSRCC.
