Akabane S, Miyake K, Iwagami M, Tanabe K, Takagi T. Machine learning-based prediction of postoperative mortality in emergency colorectal surgery: A retrospective, multicenter cohort study using Tokushukai medical database. Heliyon 2023; 9:e19695. [PMID: 37810013 PMCID: PMC10558952 DOI: 10.1016/j.heliyon.2023.e19695] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2023] [Revised: 08/29/2023] [Accepted: 08/30/2023] [Indexed: 10/10/2023] Open
Abstract
Background Although prognostic factors associated with mortality in patients with emergency colorectal surgery have been identified, an accurate mortality risk assessment is still necessary to determine the range of therapeutic resources in accordance with the severity of patients. We established machine-learning models to predict in-hospital mortality for patients who had emergency colorectal surgery using clinical data at admission and attempted to identify prognostic factors associated with in-hospital mortality. Methods This retrospective cohort study included adult patients undergoing emergency colorectal surgery in 42 hospitals between 2012 and 2020. We employed logistic regression and three supervised machine-learning models: random forests, gradient-boosting decision trees (GBDT), and multilayer perceptron (MLP). The area under the receiver operating characteristics curve (AUROC) was calculated for each model. The Shapley additive explanations (SHAP) values are also calculated to identify the significant variables in GBDT. Results There were 8792 patients who underwent emergency colorectal surgery. As a result, the AUROC values of 0.742, 0.782, 0.814, and 0.768 were obtained for logistic regression, random forests, GBDT, and MLP. According to SHAP values, age, colorectal cancer, use of laparoscopy, and some laboratory variables, including serum lactate dehydrogenase serum albumin, and blood urea nitrogen, were significantly associated with in-hospital mortality. Conclusion We successfully generated a machine-learning prediction model, including GBDT, with the best prediction performance and exploited the potential for use in evaluating in-hospital mortality risk for patients who undergo emergency colorectal surgery.

Abstract
BACKGROUND The aim of this study was to assess risk factors of mortality after unplanned surgery following colorectal resection. METHODS All the consecutive patients who underwent colorectal resection between 2011 and 2020 in a French national cohort were retrospectively included. Perioperative data of the index colorectal resection (indication, surgical approach, pathological analysis, postoperative morbidity), and characteristics of unplanned surgery (indication, time to complication, time to surgical redo) were assessed in order to identify predictive factors of mortality. RESULTS Among 547 included patients, 54 patients died (10%; 32 men; mean age = 68 ± 18 years, range 34-94 years). Patients who died were significantly older (75 ± 11 vs 66 ± 12 years, p = 0.002), frailer (ASA score 3-4 = 65 vs 25%, p = 0.0001), initially operated through open approach (78 vs 41%, p = 0.0001), and without any anastomosis (17 vs 5%, p = 0.003) than those alive. The presence of colorectal cancer, the time to postoperative complication and the time to unplanned surgery were not significantly associated to the postoperative mortality. After multivariate analysis, 5 independent predictive factors of mortality were identified: old age (OR 1.038; IC 95% 1.006-1.072; p = 0.02), ASA score = 3 (OR 5.9, CI95% 1.2-28.5, p = 0.03), ASA score = 4 (OR 9.6; IC95% 1.5-63; p = 0.02), open approach for the index surgery (OR 2.7; IC95% 1.3-5.7; p = 0.01), and delayed management (OR 2.6; IC95% 1.3-5.3; p = 0.009). CONCLUSION After unplanned surgery following colorectal surgery, one out of 10 patients dies. The laparoscopic approach during the index surgery is associated with a good prognosis in the case of unplanned surgery.

Abstract
The aim of this study is to establish the feasibility of awake laparotomy under neuraxial anesthesia (NA) in a suburban hospital. A retrospective analysis of the results of a consecutive series of 70 patients undergoing awake abdominal surgery under NA at the Department of Surgery of our Hospital from February 11th, 2020 to October 20th, 2021 was conducted. The series includes 43 cases of urgent surgical care (2020) and 27 cases of elective abdominal surgery on frail patients (2021). Seventeen procedures (24.3%) required sedation to better control patient discomfort. Only in 4/70 (5.7%) cases, conversion to general anesthesia (GA) was necessary. Conversion to GA was not related to American Society of Anesthesiology (ASA) score or operative time. Only one of the four cases requiring conversion to GA was admitted to the Intensive Care Unit (ICU) postoperatively. Fifteen patients (21.4%) required postoperative ICU support. A statistically non-significant association was observed between conversion to GA and postoperative ICU admission. The mortality rate was 8.5% (6 patients). Five out of six deaths occurred while in the ICU. All six were frail patients. None of these deaths was related to a complication of NA. Awake laparotomy under NA has confirmed its feasibility and safety in times of scarcity of resources and therapeutic restrictions, even in the most frail patients. We believe that this approach should be considered as an useful asset, especially for suburban hospitals.

Abstract
OBJECTIVE This meta-analysis aimed to investigate the effects and safety of enhanced recovery after surgery (ERAS) for the management of pediatric colorectal surgery. METHODS We retrieved relevant studies from PubMed, EMBASE, the Cochrane Library, and China National Knowledgement Infrastructure (CNKI) from its inception until 20 May 2022. Meta-analysis was performed using RevMan 5.4, and power analysis was calculated using G∗Power 3.1. RESULTS Ten studies involving 1298 patients were included for meta-analysis. Meta-analysis suggested that ERAS protocol significantly lessened intraoperative fluids (mean difference [MD], -3.11; 95% confidence interval, -4.99 to -1.22) and postoperative opioid usage (MD, -0.58; 95% CI, -1.08 to -0.26), shortened time to bowel return (MD, -12.02; 95% CI, -20.03 to -4.02), first enteral nutrition (MD, -20.88; 95% CI, -28.34 to -13.42) and oral intake (MD, -1.40; 95% CI, -1.96 to -0.84), lowered readmission rate in 30 days (relative risk [RR], 0.61, 95% CI, 0.41 to 0.90), shortened length of hospital stay (MD, -1.50; 95% CI, -1.25 to -1.09), and reduced in-hospital costs (MD, -0.26; 95% CI, -0.34 to -0.18); however, there was a comparable rate of postoperative complications between the two groups. Sensitivity analysis significantly changed the result of the readmission rate in 30 days. The statistical power of all outcomes ranged from 26.84% to 99.44%. CONCLUSIONS Our findings demonstrate the beneficial role of the ERAS protocol in accelerating rehabilitation, shortening the length of hospital stay, and decreasing in-hospital costs among pediatric patients undergoing colorectal surgery.

Abstract
The concept of enhanced recovery in colorectal surgery is a multimodal and multidisciplinary programme aiming at reducing surgical stress through optimization of patient care in the pre-, intra-, and postoperative periods. It allows to reduce postoperative morbidity and the duration of the hospital stay. We describe the case of an elderly patient with multiple comorbidities who was scheduled for a sigmoidectomy in an enhanced rehabilitation programme, and emphasize the interest and specificity of such a rehabilitation protocol for the elderly.

Abstract
This article reports the results of a novel perioperative treatment implementing the gut microbiota to prevent anastomotic fistula and leakage (AL) in patients undergoing laparoscopic colorectal resections for cancer and represents the continuation of our pilot study on 60 cases. A series of 131 patients underwent elective colorectal surgery at the S. Eugenio Hospital (Rome-Italy) between December 1, 2020, and November 30, 2022, and received a perioperative preparation following the Microbiota Implementation to Reduce Anastomotic Colorectal Leaks (MIRACLe) protocol comprising oral antibiotics, mechanical bowel preparation and perioperative probiotics. The results obtained in the MIRACLe group (MG) were compared to those registered in a Control group (CG) of 500 patients operated on between March 2015 and November 30, 2020, who received a standard ERAS protocol. Propensity score-matching (PSM) analysis was performed to overcome patients' selection bias. Patients were categorised according to perioperative preparation (MIRACLe protocol vs standard ERAS protocol) into two groups: 118 patients were in post-matched MIRACLe group (pmMG) and 356 were in post-matched Control group (pmCG). In the pmMG, only 2 anastomotic leaks were registered, and the incidence of AL was just 1.7% vs. 6.5% in the pmCG (p = 0.044). The incidence of surgical site infections (1.7% vs. 3.1%; p = 0.536), reoperations (0.8% vs. 4.2%; p = 0.136) and postoperative mortality (0% vs. 2.0%; p = 0.200) was lower in pmMG. Additionally, the postoperative outcomes were better: the times to first flatus, to first stool and to oral feeding were shorter (1 vs. 2, 2 vs. 3 and 2 vs. 3 days, respectively; p < 0.001). The postoperative recovery was faster, with a shorter time to discharge (5 vs. 6 days; p < 0.001). The MIRACLe protocol was confirmed to be safe and significantly able to reduce anastomotic leaks in patients receiving elective laparoscopic colorectal surgery for cancer.

Abstract
BACKGROUND Intraoperative ureteral injury, a serious complication of abdominopelvic surgeries, can be avoided through ureter visualization. Near-infrared fluorescence imaging offers real-time anatomical visualization of ureters during surgery. Pudexacianinium (ASP5354) chloride is an indocyanine green derivative under investigation for intraoperative ureter visualization during colorectal or gynecologic surgery in adult and pediatric patients. METHODS In this phase 2 study (NCT04238481), adults undergoing laparoscopic colorectal surgery were randomized to receive one intravenous dose of pudexacianinium 0.3 mg, 1.0 mg, or 3.0 mg. The primary endpoint was successful intraoperative ureter visualization, defined as observation of ureter fluorescence 30 min after pudexacianinium administration and at end of surgery. Safety and pharmacokinetics were also assessed. RESULTS Participants received pudexacianinium 0.3 mg (n = 3), 1.0 mg (n = 6), or 3.0 mg (n = 3). Most participants were female (n = 10; 83.3%); median age was 54 years (range 24-69) and median BMI was 29.3 kg/m2 (range 18.7-38.1). Successful intraoperative ureter visualization occurred in 2/3, 5/6, and 3/3 participants who received pudexacianinium 0.3 mg, 1.0 mg, or 3.0 mg, respectively. Median intensity values per surgeon assessment were 1 (mild) with the 0.3-mg dose, 2 (moderate) with the 1.0-mg dose, and 3 (strong) with the 3.0-mg dose. A correlation was observed between qualitative (surgeon's recognition/identification of the ureter during surgery) and quantitative (video recordings of the surgeries after study completion) assessment of fluorescence intensity. Two participants experienced serious adverse events, none of which were drug-related toxicities. One adverse event (grade 1 proteinuria) was related to pudexacianinium. Plasma pudexacianinium concentrations were dose-dependent and the mean (± SD) percent excreted into urine during surgery was 22.3% ± 8.0% (0.3-mg dose), 15.6% ± 10.0% (1.0-mg dose), and 39.5% ± 12.4% (3.0-mg dose). CONCLUSIONS In this study, 1.0 and 3.0 mg pudexacianinium provided ureteral visualization for the duration of minimally invasive, laparoscopic colorectal procedures and was safe and well tolerated.

Abstract
INTRODUCTION Pelvic exenteration (PE) surgery represents the only potentially curative treatment option for patients with locally advanced or recurrent rectal cancer (LARRC). Given the potential morbidity, whether or not PE should be recommended for an individual patient presents a major decisional conflict. This study aims to identify the outcomes of PE for which there is consensus among patients, carers and clinicians regarding their importance in guiding treatment decision-making, and to develop a risk prediction tool which predicts these outcomes. METHODS AND ANALYSIS This study will be conducted at a specialist PE centre, and employ a mixed-methods study design, divided into three distinct phases. In phase 1, outcomes of PE will be identified through a comprehensive systematic review of the literature (phase 1a), followed by exploration of the experiences of individuals who have undergone PE for LARRC and their carers (phase 1b, target sample size 10-20 patients and 5-10 carers). In phase 2, a survey of patients, their carers and clinicians will be conducted using Delphi methodology to explore consensus around the outcomes of highest priority and the level of influence each outcome should have on treatment decision-making. In phase 3 a, risk prediction tool will be developed using data from a single PE referral centre (estimated sample size 500 patients) to predict priority outcomes using multivariate modelling, and externally validated using data from an international PE collaboration. ETHICS AND DISSEMINATION Ethical approval has been granted for phases 1 and 2 (X22-0422 and 2022/ETH02659) and for maintenance of the database used in phase 3 (X13-0283 and HREC/13/RPAH/504). Informed consent will be obtained from participants in phases 1b and 2; a waiver of consent for secondary use of data in phase 3 will be sought. Study results will be submitted for publication in international and/or national peer reviewed journals. PROSPERO REGISTRATION NUMBER CRD42022351909.

Abstract
BACKGROUND Robotic colorectal surgery is becoming the preferred surgical approach for colorectal cancer (CRC). It offers several technical advantages over conventional laparoscopy that could improve patient outcomes. In this retrospective cohort study, we compared robotic and laparoscopic surgery for CRC using a national cohort of patients. METHODS Using the colectomy-targeted ACS-NSQIP database (2015-2020), colorectal procedures for malignant etiologies were identified by CPT codes for right colectomy (RC), left colectomy (LC), and low anterior resection (LAR). Optimal pair matching was performed. "Textbook outcome" was defined as the absence of 30-day complications, readmission, or mortality and a length of stay < 5 days. RESULTS We included 53,209 out of 139,759 patients screened for eligibility. Laparoscopic-to-robotic matching of 2:1 was performed for RC and LC, and 1:1 for LAR. The largest standardized mean difference was 0.048 after matching. Robotic surgery was associated with an increased rate of textbook outcomes compared to laparoscopy in RC and LC, but not in LAR (71% vs. 64% in RC, 75% vs. 68% in LC; p < 0.001). Robotic LAR was associated with increased major morbidity (7.1% vs. 5.8%; p = 0.012). For all three procedures, the mean conversion rate of robotic surgery was lower than laparoscopy (4.3% vs. 9.2%; p < 0.001), while the mean operative time was higher for robotic (225 min vs. 177 min; p < 0.001). CONCLUSIONS Robotic surgery for CRC offers an advantage over conventional laparoscopy by improving textbook outcomes in RC and LC. This advantage was not found in robotic LAR, which also showed an increased risk of serious complications. The associations highlighted in our study should be considered in the discussion of the surgical management of patients with colorectal cancer.

Abstract
INTRODUCTION Identifying the optimal treatment for anal fistula has been challenging. Since first reported in 2007, the ligation of the intersphincteric fistula tract (LIFT) procedure has reported healing rates between 40% and 95% and is being increasingly adopted. The BioLIFT is an augmentation of the LIFT with an intersphincteric bioprosthetic mesh and has reported healing rates between 69% and 94%. Despite increased costs and potential complications associated with mesh, the evidence comparing healing rates between BioLIFT and LIFT is unknown. This study details the protocol for a systematic review and meta-analysis of BioLIFT and LIFT to compare outcomes associated with each procedure. METHODS AND ANALYSIS MEDLINE, EMBASE and the Cochrane Database will be searched from inception using a search strategy designed by an information specialist. Randomised controlled trials, prospective and retrospective cohort studies, consecutive series, cross-sectional studies and case series with more than five patients will be included. Both comparative and single group studies will be included. The eligible population will be adult patients undergoing BioLIFT or LIFT for trans-sphincteric anal fistula. The primary outcome will be primary healing rate. Secondary outcomes will capture secondary healing rate and complications. Abstract, full text and data extraction will be completed independently and in duplicate by two reviewers. Study risk of bias will be assessed using Risk of Bias In Non-randomized Studies - of Interventions and the Risk of Bias (RoB 2.0) tool. Quality of evidence for outcomes will be evaluated using Grading of Recommendations, Assessment, Development and Evaluations criteria. A meta-analysis will be performed using a random-effects inverse variance model. Subgroup and sensitivity analyses will be explored in relation to complex fistula characteristics and patients who have undergone previous LIFT. Heterogeneity will be assessed using the I2 statistic. ETHICS AND DISSEMINATION This review does not require research ethics board approval. This study will be completed in September 2022. The findings of this study will be disseminated through peer-reviewed international conferences and journals. PROSPERO REGISTRATION NUMBER CRD42020127996.

Abstract
PURPOSE Abdominoperineal resection (APR) remains a key procedure for the treatment of low rectal/anorectal cancers. However, perineal wound closure remains challenging, particularly in extralevator abdominoperineal resection (ELAPR) due to gapped tissue planes. Different approaches have been attempted to improve perineal wound repair. The aim of this study is to report our 6-year experience in perineal wound closure utilising biological mesh. METHODS We conducted a retrospective study using data from our prospectively maintained database, including patients who underwent APR with perineal mesh closure between 2016 and 2021. RESULTS 49 patients underwent APR with perineal mesh reconstruction for low rectal cancer during the 6-year period. Of these, 63% were males, with a mean age of 68 (± 11), and a mean BMI of 27.9 (± 13.7). 49% (24) of patients received neoadjuvant therapy. 88% (43) of patients underwent standard "S-APR" and only 12% (6) underwent ELAPR. Majority of procedures were laparoscopic (87.8%) with conversion rate of 6.9%. Mean length of stay was 11.7 (± 11.6). The perineal wound infection rate was 30% and only two patient required mesh removal due to entero-cutaneous perineal fistula and pelvic abscess. Perineal hernia was found in only two patients (4.1%). CRM was negative in 81.6% of the patients. Mean follow-up period was 29.2 (± 16.5) months, and disease recurrence occurred in 9 (18.3%) patients with average number of months for recurrence of 21 (± 7). Overall survival during the follow-up period was 91%. CONCLUSION Our series shows a favourable short- and medium-term outcome with routine insertion of mesh for perineal wound closure.

Abstract
INTRODUCTION In locally recurrent rectal cancer (LRRC), surgery is a standard treatment for resectable disease. However, short-term and long-term outcomes are unsatisfactory due to the invasive nature of surgical procedures and the high proportion of local recurrence. Consequently, the identification of reliable prognostic and predictive biomarkers to guide treatment decisions may improve outcomes. The presence of circulating tumour DNA (ctDNA) in plasma after surgery may signify the presence of minimal residual disease (MRD) in various cancers. Therefore, we have launched a multi-institutional prospective observational study of ctDNA for MRD detection in conjunction with JCOG1801, a randomised, controlled phase III trial evaluating the efficacy of preoperative chemoradiotherapy (pre-CRT) compared with up-front surgery for LRRC (jRCTs031190076, NCT04288999). METHODS AND ANALYSIS JCOG1801A1 is the first correlative study that assesses ctDNA in LRRC patients enrolled in JCOG1801. Patients randomised to up-front surgery will provide whole blood samples at three time points (prior to surgery, after surgery and after postoperative chemotherapy); those to pre-CRT will provide at five time points (prior to pre-CRT, after pre-CRT, prior to surgery, after surgery and after postoperative chemotherapy). Cell-free DNA will be extracted from plasma and analysed by Guardant Reveal, a tumour tissue-agnostic assay that assesses both genomic alterations and methylation patterns to determine the presence or absence of ctDNA. We will compare the prognosis and treatment response of patients according to their ctDNA status after surgery and at other time points. ETHICS AND DISSEMINATION The study protocol received approval from the Institutional Review Board of National Cancer Center Hospital East on behalf of the participating institutions in February 2023. The study is conducted in accordance with the precepts established in the Declaration of Helsinki and Ethical Guidelines for Medical and Biological Research Involving Human Subjects. Written informed consent will be obtained from all eligible patients prior to registration.

Surgical outcome improvement by shared decision-making: value of a preoperative multidisciplinary target clinic for the elderly in colorectal surgery. Langenbecks Arch Surg 2023; 408:316. [PMID: 37584868 DOI: 10.1007/s00423-023-03031-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2023] [Accepted: 07/24/2023] [Indexed: 08/17/2023]
Abstract
PURPOSE Frailty and comorbidities increase the risk of postoperative complications and raise treatment costs. Perioperative optimisation is shown to improve surgical outcomes for the elderly. The aim of this study was to assess the impact of introducing a multidisciplinary preoperative clinic for older patients (Colchester Older Persons' Evaluation for Surgery (COPES) clinic) undergoing major colorectal surgery. METHODS This 5-year single centre study included patients >65 years with ≥3 comorbidities undergoing major colorectal surgery. From October 2018, patients with these characteristics were evaluated and optimised in the COPES clinic by a geriatrician and an anaesthetist. Outcomes were compared to high-risk patients operated on prior to COPES (pre-COPES group). The primary outcomes were postoperative morbidity at discharge and 6 months measured by the Comprehensive Complication Index. Patients were matched on age and number of comorbidities. RESULTS A total of 54 patients were enrolled in the pre-COPES and 18 in the COPES group. After matching, the results were comparable for both groups. The length of stay was shorter in the COPES group and the recurrence rate was higher; however, it did not reach statistical significance in both findings. CONCLUSION This clinic intends to improve treatment quality, placing emphasis on shared decision-making. More focus should be put on patient-reported outcomes and experiences. Especially for elderly patients, quality of life and maintaining independence are often their priority. To determine the true value of a preoperative multidisciplinary clinic targeting elderly comorbid patients, a prospective study with larger cohort is needed, focusing not only on objective outcomes but also on patient-reported outcomes.

Abstract
Background The use of probiotics positively modifies the composition and function of the intestinal flora, decreasing inflammation, and these changes improve the quality of intestinal anastomosis. Therefore, the objective of this study was to evaluate the metagenomics of the microbial community after probiotic supplementation in rats subjected to intestinal anastomosis. Methods The probiotic chosen for this study was composed of the strains Lactobacillus paracasei LPC37, Bifidobacterium lactis HN0019, Lactobacillus rhamnosus HN001 and Lactobacillus acidophilus NCFM. Both groups underwent two colostomies, one in the right colon and the second in the rectosigmoid colon, followed by anastomosis with eight interrupted stitches. The rats were killed on the fifth day of PO. Changes in the intestinal microbiota were evaluated by means of a metagenomic study that evaluated bacterial alpha and beta diversity indices. Results Although there were no significant differences for any alpha diversity index, changes were observed for beta diversity indexes in the microbiota of rats. The group that received the probiotic preserved and even increased the abundance of beneficial bacterial genera and, at the same time, decreased the abundance of potentially pathogenic bacteria, promoting a favorable environment for anastomoses' healing. Conclusion The use of probiotics had a positive impact on the quality of the intestinal microbiota.

Tech Coloproctol 2023; 27:639-645. [PMID: 36264522 DOI: 10.1007/s10151-022-02716-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/21/2022] [Accepted: 10/11/2022] [Indexed: 10/24/2022]
Abstract
BACKGROUND Computed tomography (CT) scan with rectal contrast enema (RCE-CT) could increase the detection rate of anastomotic leaks (AL) in the early postoperative period following colorectal surgery, compared to CT scan without RCE. The aim of this study was to assess the benefit of RCE-CT for the early diagnosis of AL following colorectal surgery. METHODS Patients who had a RCE-CT for suspected AL in the early postoperative period following colorectal surgery with anastomosis between January 2012 and July 2019 at the Dijon University Hospital were retrospectively included. All images were reviewed by two independent observers who were blinded to the original report. The reviewers reported for each patient whether an AL was present or not in each imaging modality (CT scan, then RCE-CT). Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were then calculated to determine the diagnostic performance of each modality. RESULTS One hundred and thirty-nine patients were included. RCE-CT had an increased NPV compared to CT scan (82% vs 77% (p = 0.02) and 84% vs 68% (p < 0.0001) for observers 1 and 2, respectively). RCE-CT had an increased sensitivity compared to CT scan (79% vs 48% (p < 0.0001) for observer 2). RCE-CT had a significant lower false-negative rate for both observers: 18% vs 23% (p = 0.02) and 16% vs 32% (p < 0.0001). CONCLUSIONS RCE-CT improved the detection rates of AL in the early period following colorectal surgery. RCE-CT should be recommended when a CT scan is negative and AL is still suspected.

Abstract
BACKGROUND The aim of this study was to evaluate the influence of the institutional volume of abdominoperineal resections (APR) on the short-term outcomes and costs in the Brazilian Public Health system. METHODS This population-based study evaluated the number of APRs by institutions performed in the Brazilian Public Health system from January/2010 to July/2022. Data were extracted from a public domain from the Brazilian Public Health system. RESULTS Four hundred and twelve hospitals performed APRs and were included. Only 23 performed at least 5 APRs per year on average and were considered high-volume institutions. The linear regression model showed that the number of hospital admissions for APRs was negatively associated with in-hospital mortality (Coef. = - 0.001; p = 0.013) and length of stay in the intensive care unit (Coef. = - 0.006; p = 0.01). The number of hospital admissions was not significantly associated with personnel, hospital, and total costs. The in-hospital mortality in high-volume institutions was significantly lower than in low-volume institutions (2.5 vs. 5.9%; p: < 0.001). The mean length of stay in the intensive care unit was shorter in high-volume institutions (1.23 vs. 1.79 days; p = 0.021). In high-volume institutions, the personnel (R$ 952.23 [US$ 186.64] vs. R$ 11,129.04 [US$ 221.29]; p = 0.305), hospital (R$ 4078.39 [US$ 799.36] vs. R$ 4987.39 [US$ 977.53]; p = 0.111), and total costs (R$ 5030.63 [US$ 986.00] vs. R$ 6116.71 [US$ 1198.88]; p = 0.226) were lower. CONCLUSIONS Higher institutional APR volume is associated with lower in-hospital mortality and less demand for intensive care. The findings of this nationwide study may affect how Public Health manages APR care.

Selective Decontamination with Oral Antibiotics in Colorectal Surgery: 90-day Reintervention Rates and Long-term Oncological Follow-up. J Gastrointest Surg 2023; 27:1685-1693. [PMID: 37407901 DOI: 10.1007/s11605-023-05746-1] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/03/2023] [Accepted: 04/25/2023] [Indexed: 07/07/2023]
Abstract
BACKGROUND Oral antibiotics (OAB) in colorectal surgery have been shown to reduce surgical site infections (SSIs) and possibly anastomotic leakage. However, evidence on long-term follow-up, reintervention rates and 5-year oncological follow-up is lacking. The current study aims at elucidating this knowledge gap. METHODS This study evaluated the long-term effectiveness of perioperative 'Selective decontamination of the digestive tract' (SDD) in colorectal cancer surgery. The primary outcome was anastomotic leakage within 90 days, secondary outcomes included infectious complications, reinterventions, readmission, hospital stay, and 5-year overall and disease-free-survival. Statistical analysis including univariate and multivariate analysis was performed to identify predictors of 90-day outcomes, and Kaplan-Meier survival analysis was used for the 5-year survival outcomes. RESULTS In total 455 patients were analyzed, 228 participants in the SDD group and 227 in the control group. Anastomotic leakage rate was not statistically different between the SDD and control group (6.6% versus 9.7%). One or more infectious complications occurred in 15.4% of patients in the SDD group and in 28.2% in the control group (OR 0.46, 95% C.I. 0.29 - 0.73). In the SDD group 8,8% of patients required a reintervention compared to 16,3% of patients in the control group (OR 0.47, 95% C.I. 0.26 - 0.84). After multivariable analysis SDD remained significant in reducing both infectious complications and reinterventions after 90-days follow-up. There was no difference between SDD and control group in 5-year overall survival and disease-free-survival. CONCLUSION SDD as OAB is effective in reducing 90-days postoperative infectious complications and reinterventions. As such, SDD as standard OAB in elective colorectal surgery is highly recommended.

Abstract
PURPOSE Hemorrhoids are the most common benign anorectal diseases. Mucopexy strengthens the anal canal mucosa, which can be performed alone or in combination with Doppler-guided hemorrhoidal artery ligation (DG-HAL). In this study, we compared the postoperative complications between simple mucopexy plus HAL with and without a Doppler guide. METHODS This study was performed as a single-blinded randomized clinical trial. Patients referred to a tertiary colorectal referral clinic with grades 3 and 4 hemorrhoids who were candidates for surgical intervention entered the study. Thirty-six patients were randomly divided into 2 groups. Group A including 18 patients underwent mucopexy and DG-HAL and the other 18 patients (group B) underwent standard mucopexy and HAL without a Doppler guide. Postoperative pain score and the duration of oral analgesic consumption were recorded. Additionally, postoperative symptoms and complications were recorded and compared between the 2 methods. RESULTS There was no significant difference between the 2 groups in terms of pain score and the duration of postoperative analgesic consumption as well as the incidence of postoperative complications. Besides, the primary grade of hemorrhoids was not significantly associated with recurrence, but there was a significant association between body mass index and Wexner score (WS) with recurrence. The mean WS of patients showed a significant decrease in both groups postoperatively. However, the rate of WS reduction was not remarkably different between the 2 groups. CONCLUSION Simple mucopexy with blind HAL (without Doppler guide) might be considered for the treatment of grades 3 and 4 hemorrhoids effectively.

Abstract
Background The healthcare sector faces increasing pressure to improve environmental sustainability whilst continuing to meet the needs of patients. One strategy is to lower the avoidable demand on healthcare services, by reducing the number of surgical complications, such as anastomotic leak (AL). The aim of this study was to assess the environmental impact associated with the care pathway of AL. Methods An environmental impact assessment was performed according to the Sustainable Healthcare Coalition (SHC) guidelines. A care pathway, describing the typical steps involved in the diagnosis and treatment of AL was developed. Activity and emission data for each stage of the care pathway were used to calculate the climate, water and waste impact of the treatment of AL patients. Results The environmental impact assessment shows that AL is associated with an average climate, water and waste impact per patient of 1303 kg CO2-eq, 1803 m3 of water and 123 kg waste, respectively. Grade C leaks are associated with the greatest environmental impact, contributing to 89.3 %, 79.4 % and 97.9 % of each impact, respectively. A breakdown of the environmental impact of each activity shows that stoma home management is the largest contributor to the total climate (46.6 %) and waste (47.3 %) impact of AL patients, whilst in-patient hospital stay contributes greatest to the total water impact (46.7 %). Conclusions The treatment of AL is associated with a substantial environmental impact. This study is, to our knowledge, the first to assess the environmental impact associated with the treatment of AL.

Abstract
PURPOSE Previous studies have suggested that coffee may shorten the postoperative ileus period. We sought to evaluate the impact of both coffee and caffeine on shortening the return of postoperative bowel function following minimally invasive colectomy. METHODS This was a single-center, randomized controlled clinical trial conducted in a tertiary hospital. Patients undergoing an elective robotic or laparoscopic small or large bowel operation were included in this study. Patients were randomized into one of three groups: warm water, decaffeinated coffee, and caffeinated coffee. Subjects were assigned to drink a 4-oz cup three times daily starting on postoperative day one. The primary endpoint was time to first bowel movement. Secondary endpoints included time to first flatus, length of hospital stay, and postoperative morbidity. RESULTS A total of 99 patients were included in this study: 31 warm water, 31 decaffeinated coffee, and 37 caffeinated coffee. The groups were similar in age and sex (p = 0.51 and 0.91, respectively). Mean (SD) time to the first bowel movement in days was 2.94 (1.4), 2.58 (1.2), and 2.86 (1.3), respectively (p = 0.53). There were no significant differences observed in postoperative morbidity (p = 0.52) between groups. Multivariate linear regression analysis did not reveal a statistically significant association between any interventions and time to first bowel movement or length of hospital stay. CONCLUSIONS Coffee (caffeinated or decaffeinated) does not expedite the return of bowel function following minimally invasive operation. TRIAL REGISTRATION https://classic.

Abstract
BACKGROUND Technological development has offered laparoscopic colorectal surgeons new video systems to improve depth perception and perform difficult task in limited space. The aim of this study was to assess the cognitive burden and motion sickness for surgeons during 3D, 2D-4 K or 3D-4 K laparoscopic colorectal procedures and to report post-operative data with the different video systems employed. METHODS Patients were assigned to either 3D, 2D-4 K or 3D-4 K video and two questionnaires (Simulator Sickness Questionnaire-SSQ- and NASA Task Load Index -TLX) were used during elective laparoscopic colorectal resections (October 2020-August 2022) from two operating surgeons. Short-term results of the operations performed with the three different video systems were also analyzed. RESULTS A total of 113 consecutive patients were included: 41 (36%) in the 3D Group (A), 46 (41%) in the 3D-4 K Group and 26 (23%) in the 2D-4 K Group (C). Weighted and adjusted regression models showed no significant difference in cognitive load amongst the surgeons in the three groups of video systems when using the NASA-TLX. An increased risk for slight/moderate general discomfort and eyestrain in the 3D-4 K group compared with 2D-4 K group (OR = 3.5; p = 0.0057 and OR = 2.8; p = 0.0096, respectively) was observed. Further, slight/moderate difficulty focusing was lower in both 3D and 3D-4 K groups compared with 2D-4 K group (OR = 0.4; p = 0.0124 and OR = 0.5; p = 0.0341, respectively), and higher in the 3D-4 K group compared with 3D group (OR = 2.6; p = 0.0124). Patient population characteristics, operative time, post-operative staging, complication rate and length of stay were similar in the three groups of patients. CONCLUSIONS 3D and 3D-4 K systems, when compared with 2D-4 K video technology, have a higher risk for slight/moderate general discomfort and eyestrain, but show lower difficulty focusing. Short post-operative outcomes do not differ, whichever imaging system is used.

Abstract
Background Intraoperative ureteral injury (IUI) during colorectal surgery can have devastating consequences. This study aimed to assess the clinical and economic impact of pre-operative ureteral stenting in colorectal surgeries. Methods A retrospective cohort study was conducted using United States hospital data (October 2015 - December 2019). IUI incidence was examined across selected inpatient surgery types (elective colectomy, enterectomy, proctectomy, enterostomy, other colorectal procedures; emergency colectomy). Stenting effectiveness was evaluated as the difference in IUI and intraoperative detection rates between propensity score-matched groups. The additional hospital cost for stenting was also estimated considering the savings from IUIs that were potentially avoidable or detected by stenting. Results In total, 283,549 colorectal surgeries were analyzed. Across surgery types, stent use and IUI incidence ranged from 1.47% - 8.86% and from 0.91% - 2.90%, respectively. Stents were used in 6.75% of elective colectomy cases, where they were associated with an absolute reduction of 1.14 percentage points (95% CI: -1.85 to -1.03) in IUI rate and a 21.6 percentage point reduction in the intraoperative detection rate. Additional hospital costs for stenting ranged from $1,464 - $4,436 across surgery types. Additional results varied by case but were consistent with the colectomy example. Conclusions While effective in limited settings, the IUI reduction attributed to stenting and ability to shift IUI detection to the intraoperative setting could not offset the hospital cost of stent placement during colectomy (and colorectal surgery, in general). There thus remains an ongoing need in colorectal surgery for a universal, cost-effective solution to prevent IUI.

Abstract
PURPOSE The da Vinci SP® (dVSP) surgical system (Intuitive Surgical, Sunnyvale, CA, USA), a robotic platform designed for single-incision surgery, overcame the need for multiple ports in traditional robotic surgery and issues including triangulation and retraction in single-incision laparoscopic surgery. However, previous studies only included case reports or series with small sample sizes. The aim of this study was to assess the safety and performance of the dVSP surgical system and its instruments and accessories for colorectal procedures. METHODS The medical records of patients who had surgery with the dVSP from March 2019 to September 2021 at Ewha Womans University Seoul Hospital were investigated. The pathologic and follow-up data of patients who had malignant tumors were analyzed separately to evaluate oncological safety. RESULTS Fifty patients (26 male and 24 female) with a median age of 59 years (interquartile range 52.5-63.0 years) were enrolled. The procedures included low anterior resection with total mesorectal excision (n = 16), sigmoid colectomy with complete mesocolic excision and central vessel ligation (CME + CVL) (n = 14), right colectomy with CME + CVL (n = 9), left colectomy with CME + CVL (n = 4), right colectomy (n = 6), and sigmoid colectomy (n = 1). Operative time significantly decreased after 25 cases (early phase vs. late phase; operative time 295.0 min vs. 250.0 min, p = 0.015; docking time 16.0 min vs. 12.0 min, p = 0.001; console time 212.0 min vs. 190.0 min, p = 0.019). Planned procedures were successfully completed in all patients. Postoperative outcomes were acceptable with only six cases of mild adverse events through a 3-month follow-up. No local recurrence and only one case of systemic recurrence occurred within 1 year postoperatively. CONCLUSIONS This study demonstrated the surgical and oncological safety and feasibility of dVSP, which may be a novel surgical platform for colorectal surgery.

Abstract
PURPOSE Clinical experience shows complaints similar to LARS not only after rectal surgery, but even after other types of colorectal surgery. Our aim was to investigate the occurrence of LARS after several types of colorectal surgery and its impact on quality of life. METHODS We included adult patients who underwent colorectal surgery at our centre from January 2016 until March 2019, regardless of indication. A questionnaire was sent evaluating LARS and quality of life. RESULTS The questionnaire was answered by 119 patients. We noticed highest LARS-score after rectum surgery (26.1), but also surprisingly higher LARS-score after right-sided colectomy (21.0) compared to left-sided colectomy (16.4). We report lowest quality of life after rectal surgery, but higher quality of life in left colectomy compared to right colectomy. CONCLUSION LARS-score did not significantly correlate with type of procedure; however, higher LARS-scores were noted after right-sided colectomy compared to left-sided colectomy with similar impact on quality of life. We suggest CORS (colorectal resection syndrome) as a more suiting conceptual name instead of LARS to describe functional bowel complaints after colorectal surgery.

Abstract
INTRODUCTION Within the last two decades, major advances have been made in the surgical approach for patients with colorectal cancer. However, to this day we face considerable challenges in reducing surgery-related complications and improving long-term oncological outcomes. Unprecedented response rates have been achieved in studies investigating immunotherapy in patients with mismatch repair deficient (dMMR) colorectal cancer. This has raised the question of whether neoadjuvant immunotherapy may change the standard of care for localised dMMR colon cancer and pave the way for organ-sparing treatment. METHODS AND ANALYSIS This is an investigator-initiated, multicentre, prospective, single-arm, phase II study in patients with stage I-III dMMR colon cancer scheduled for intended curative surgery. Eighty-five patients will be treated with one dose of pembrolizumab (4 mg/kg) and within 5 weeks will undergo a re-evaluation with an endoscopy and a CT scan-to assess tumour response-before standard resection of the tumour. The primary endpoint is the number of patients with pathological complete response, and secondary endpoints include safety (number and severity of adverse events) and postoperative surgical complications. In addition, we aspire to identify predictive biomarkers that can point out patients that achieve pathological complete response. ETHICS AND DISSEMINATION The Regional Committee for Health Research and Ethics and the Danish Medicines Agency have approved this study. The study will be performed according to the Helsinki II declaration. Written informed consent will be obtained from all participants. The results of the study will be submitted to peer-reviewed journals for publication and presented at international congresses. TRIAL REGISTRATION NUMBER NCT05662527.

Abstract
PURPOSE OF THE STUDY To compare the relationships between two CT derived sarcopenia assessment methods, and compare their relationship with inter-rater and intrarater validations and colorectal surgical outcomes. STUDY DESIGN 157 CT scans were identified across Leeds Teaching Hospitals National Health Service Trust for patients undergoing colorectal cancer surgery. 107 had body mass index data available, required to determine sarcopenia status. This work explores the relationship between sarcopenia, as measured by both total cross sectional-area (TCSA) and psoas-area (PA) and surgical outcomes. All images were assessed for inter-rater and intrarater variability for both TCSA and PA methods of sarcopenia identification. The raters included a radiologist, an anatomist and two medical students. RESULTS Prevalence of sarcopenia was different when measured by PA (12.2%-22.4%) in comparison to TCSA (60.8%-70.1%). Strong correlation exists between muscle areas in both TCSA and PA measures, however, there were significant differences between methods after the application of method-specific cut-offs. There was substantial agreement for both intrarater and inter-rater comparisons for both TCSA and PA sarcopenia measures. Outcome data were available for 99/107 patients. Both TCSA and PA have poor association with adverse outcomes following colorectal surgery. CONCLUSIONS CT-determined sarcopenia can be identified by junior clinicians, those with anatomical understanding and radiologists. Our study identified sarcopenia to have a poor association with adverse surgical outcomes in a colorectal population. Published methods of identifying sarcopenia are not translatable to all clinical populations. Currently available cut-offs require refinement for potential confounding factors, to provide more valuable clinical information. WHAT IS ALREADY KNOWN ON THIS TOPIC? WHAT DOES THIS STUDY ADD? HOW MIGHT THIS STUDY AFFECT RESEARCH, PRACTICE OR POLICY?

Abstract
PURPOSE The growth of Singapore's geriatric population, coupled with the rise in colorectal cancer (CRC), has increased the number of colorectal surgeries performed on elderly patients. This study aimed to compare the clinical outcomes and costs of laparoscopic versus open elective colorectal resections in elderly CRC patients over 80 years. METHODS A retrospective cohort study using data from the American College of Surgeons National Surgery Quality Improvement Program (ACS-NSQIP) identified patients over 80 years undergoing elective colectomy and proctectomy between 2018 and 2021. Patient demographics, length of stay (LOS), 30-day postoperative complications, and mortality rates were analysed. Cost data in Singapore dollars were obtained from the finance database. Univariate and multivariate regression models were used to determine cost drivers. The 5-year overall survival (OS) for the entire octogenarian CRC cohort with and without postoperative complications was estimated using the Kaplan-Meier curves. RESULTS Of the 192 octogenarian CRC patients undergoing elective colorectal surgery between 2018 and 2021, 114 underwent laparoscopic resection (59.4%), while 78 underwent open surgery (40.6%). The proportion of proctectomy cases was similar between laparoscopic and open groups (24.6% vs. 23.1%, P = 0.949). Baseline characteristics, including Charlson Comorbidity Index, albumin level, and tumour staging, were comparable between both groups. Median operative duration was 52.5 min longer in the laparoscopic group (232.5 vs. 180.0 min, P < 0.001). Both groups had no significant differences in postoperative complications and 30-day and 1-year mortality rates. Median LOS was 6 days in the laparoscopic group compared to 9 days in the open group (P < 0.001). The mean total cost was 11.7% lower in the laparoscopic group (S$25,583.44 vs. S$28,970.85, P = 0.012). Proctectomy (P = 0.024), postoperative pneumonia (P < 0.001) and urinary tract infection (P < 0.001), and prolonged LOS > 6 days (P < 0.001) were factors contributing to increased costs in the entire cohort. The 5-year OS of octogenarians with minor or major postoperative complications was significantly lower than those without complications (P < 0.001). CONCLUSION Laparoscopic resection is associated with significantly reduced overall hospitalization costs and decreased LOS compared to open resection among octogenarian CRC patients, with comparable postoperative outcomes and 30-day and 1-year mortality rates. The extended operative time and higher consumables costs from laparoscopic resection were mitigated by the decrease in other inpatient hospitalization costs, including ward accommodation, daily treatment fees, investigation costs, and rehabilitation expenditures. Comprehensive perioperative care and optimised surgical approach to mitigate the impact of postoperative complications can improve survival in elderly patients undergoing CRC resection.

Abstract
Rectal prolapse is a circumferential, full-thickness protrusion of the rectum through the anus. It is a rare condition, and only affects 0.5% of the general population. Multiple treatment modalities have been described, which have changed significantly over time. Particularly in the last decade, laparoscopic and robotic surgical approaches with different mobilization techniques, combined with medical therapies, have been widely implemented. Because patients have presented with a wide range of complaints (ranging from abdominal discomfort to incomplete bowel evacuation, mucus discharge, constipation, diarrhea, and fecal incontinence), understanding the extent of complaints and ruling out differential diagnoses are essential for choosing a tailored surgical procedure. It is crucial to assess these additional symptoms and their severities using preoperative scoring systems. Additionally, radiological and physiological evaluations may explain some vague symptoms and reveal concomitant pelvic disorders. However, there is no consensus on or standardization of the optimal extent of dissection, type of procedure, and materials used for rectal fixation; this makes providing maximum benefits to patients with minimal complications difficult. Even recent publications and systematic reviews have not recommended the most appropriate treatment options. This review explains the appropriate diagnostic tools for different conditions and summarizes the current treatment approaches based on existing literature and expert opinions.

Abstract
Purpose The effect of prehabilitation in patients with frailty undergoing colorectal cancer surgery remains controversial. This meta-analysis aimed to assess the impact of prehabilitation before colorectal surgery on the functional outcomes and postoperative complications in patients with frailty undergoing colorectal cancer surgery. Methods PubMed, EMBASE, Cochrane Library, and Scopus databases were searched for articles published up to November 9, 2022. We included randomized and non-randomized trials in which the effects of prehabilitation in patients with frailty undergoing colorectal cancer surgery were investigated against a control group. Data extracted for our meta-analysis included the 6-minute walk test (6MWT), postoperative incidence of complications (Clavien-Dindo classification ≥IIIa), comprehensive complication index (CCI), and length of stay (LOS) in the hospital. Results Compared with the control group, we found a significant improvement in the incidence of postoperative complications and shorter LOS in the hospital in the prehabilitation group. However, the 6MWT and CCI results showed no significant differences between the 2 groups. Conclusion Prehabilitation in patients with frailty who underwent colorectal cancer surgery improved the incidence of postoperative complications and LOS in the hospital. Hence, clinicians should consider conducting or recommending prehabilitation exercises prior to colorectal cancer surgery in patients with frailty.

Abstract
Background Gender disparity and hidden discrimination remained in the surgical subspecialties. This study aimed to explore the authorship gender composition in four high-impact colorectal surgery journals over the past two decades. Method This cross-sectional study queried the Web of Science Core Collection database and PubMed (MEDLINE) for articles published in four high-impact colorectal surgery specialty journals between 2000 and 2021 (Database accessed at July 2022). Extracted data included authors' full names, institutions, year of publication and total citation numbers. Authors' genders were assigned via gendrize.io, a third-party name predictor tool. Results 100,325 authorship records were included in the final analysis. 21.8% of writers were identified as female, an increase from 11.4% (95% CI, 9.4%-13.3%) in 2000 to 26.5% (95% CI, 25.6%-27.4%) in 2021. Female authorship has risen in all authorship types, but women physicians were less likely to be the last authors than the first (OR, 0.63; 95%CI, 0.6-0.67) or middle authors (OR, 0.57; 95%CI, 0.55-0.60). Female authorship has also increased substantially in different document types, but female authorships were less likely in editorials than original articles (OR, 0.76; 95%CI, 0.7-0.83) and reviews (OR, 0.83; 95%CI, 0.74-0.94). Compared with male physicians, females were more likely to author in publications with reportable funding, either as first authors (OR, 1.46; 95%CI, 1.12-1.78) or last authors (OR, 1.51; 95%CI, 1.22-1.89). Authorship varied geographically, and countries with the highest female authorship percentage were mainly in Europe and North America. Conclusion Female authorship has grown substantially in colorectal surgery literature. However, female physicians were still underrepresented and less likely to assume senior or leading authorship roles.

Abstract
PURPOSE Surgical site infection (SSI) impacts 5-20% of patients after elective colorectal surgery. There are varying reports on the effectiveness of oral antibiotics (OAB) with preoperative mechanical bowel preparation (MBP) in preventing SSI. We aim to determine the role of OAB and MBP in preventing SSI after elective colorectal surgery. We also determine if a specific OAB regimen will be more effective than others. METHODS This study investigated the impact of OAB and MBP in patients undergoing elective colorectal surgery. PubMed, MEDLINE, Ovid, Cochrane Central Register of Controlled Trials, ACP Journal Club, and Embase databases were searched for randomized clinical trials (RCTs) published by June 2022. All RCTs comparing various preoperative bowel preparation regimens, including pairwise or multi-intervention comparisons, were included. To establish the role of OAB and MBP in preventing SSI, we conducted a Bayesian network meta-analysis on all RCTs. We further performed subgroup analysis to determine the most effective OAB regimen. RESULTS Among included 46 studies with a total of 12690 patients, patients in the MBP + OAB group were less likely to have SSI than those having MBP-only (OR 0.55, 95% CrI 0.39-0.76), and without MBP and OAB (OR 0.52, 95% CrI 0.32-0.84). OAB regimen C (kanamycin + metronidazole) and A (neomycin + metronidazole) demonstrated a significantly reduced incidence of SSI, compared to regimen B (neomycin + erythromycin) with OR 0.24 (95% CrI 0.07-0.79) and 0.26 (95% CrI 0.07-0.99) respectively. CONCLUSIONS OAB with MBP reduces the risk of SSI after elective colorectal surgery. Providing adequate aerobic and anaerobic coverage with OAB may confer better protection against SSI.

Abstract
Colorectal cancer (CRC) is one of the most common malignancies in the world. Despite significant improvements in surgical technique, postoperative complications still occur in a fair percentage of patients undergoing colorectal surgery. The most feared complication is anastomotic leakage. It negatively affects short-term prognosis, with increased post-operative morbidity and mortality, higher hospitalization time and costs. Moreover, it may require further surgery with the creation of a permanent or temporary stoma. While there is no doubt about the negative impact of anastomotic dehiscence on the short-term prognosis of patients operated on for CRC, still under discussion is its impact on the long-term prognosis. Some authors have described an association between leakage and reduced overall survival, disease-free survival, and increased recurrence, while other Authors have found no real impact of dehiscence on long term prognosis. The purpose of this paper is to review all the literature about the impact of anastomotic dehiscence on long-term prognosis after CRC surgery. The main risk factors of leakage and early detection markers are also summarized.

Abstract
The therapy of left-sided malignant colonic obstruction continues to be one of the largest problems in clinical practice. Numerous studies on colonic stenting for neoplastic colonic obstruction have been reported in the last decades. Thereby the role of self-expandable metal stents (SEMS) in the treatment of malignant colonic obstruction has become better defined. However, numerous prospective and retrospective investigations have highlighted serious concerns about a possible worse outcome after endoscopic colorectal stenting as a bridge to surgery, particularly in case of perforation. This review analyzes the most recent evidence in order to highlight pros and cons of SEMS placement in left-sided malignant colonic obstruction.

Abstract
BACKGROUND This study aimed to investigate the association between the drainage quantity of pelvic drains and postoperative complications in colorectal surgery. MATERIALS AND METHODS This retrospective single-center study enrolled 122 colorectal surgery patients between January 2017 and December 2020. After restorative proctectomy or proctocolectomy with gastrointestinal anastomosis, a continuous, low-pressure suction pelvic drain was placed and its contents measured. Removal ensued following the absence of turbidity and a drainage quantity of ≤ 150 mL/day. RESULTS Seventy-five patients (61.5%) and 47 patients (38.5%) underwent restorative proctectomy and proctocolectomy, respectively. Drainage quantity changes were observed on postoperative day (POD) 3, regardless of the surgical procedure or postoperative complications. The median (interquartile range) number of PODs before drain removal and organ-space surgical site infection (SSI) diagnosis were 3 (3‒5) and 7 (5‒8), respectively. Twenty-one patients developed organ-space SSIs. Drains were left in place in two patients after POD 3 owing to large drainage quantities. Drainage quality changes enabled diagnosis in two patients (1.6%). Four patients responded to therapeutic drains (3.3%). CONCLUSIONS The drainage quantity of negative-pressure closed suction drains diminishes shortly after surgery, regardless of the postoperative course. It is not an effective diagnostic or therapeutic drain for organ-space SSI. This supports early drain removal based on drainage quantity changes in actual clinical practice. TRIAL REGISTRATION The study protocol was retrospectively registered and carried out per the Declaration of Helsinki and approved by the Hiroshima University Institutional Review Board (approval number: E-2559).

Abstract
BACKGROUND Large-scale quality improvement interventions demand robust trial designs with flexibility for delivery in different contexts, particularly during a pandemic. We describe innovative features of a batched stepped wedge trial, ESCP sAfe Anastomosis proGramme in CoLorectal SurgEry (EAGLE), intended to reduce anastomotic leak following right colectomy, and reflect on lessons learned about the implementation of quality improvement programmes on an international scale. METHODS Surgical units were recruited and randomised in batches to receive a hospital-level education intervention designed to reduce anastomotic leak, either before, during, or following data collection. All consecutive patients undergoing right colectomy were included. Online learning, patient risk stratification and an in-theatre checklist constituted the intervention. The study was powered to detect an absolute risk reduction of anastomotic leak from 8.1 to 5.6%. Statistical efficiency was optimised using an incomplete stepped wedge trial design and study batches analysed separately then meta-analysed to calculate the intervention effect. An established collaborative group helped nurture strong working relationships between units/countries and a prospectively designed process evaluation will enable evaluation of both the intervention and its implementation. RESULTS The batched trial design allowed sequential entry of clusters, targeted research training and proved to be robust to pandemic interruptions. Staggered start times in the incomplete stepped wedge design with long lead-in times can reduce motivation and engagement and require careful administration. CONCLUSION EAGLE's robust but flexible study design allowed completion of the study across globally distributed geographical locations in spite of the pandemic. The primary outcome analysed in conjunction with the process evaluation will ensure a rich understanding of the intervention and the effects of the study design.

Abstract
BACKGROUND Anastomotic leakage has been reported to occur when the load on the anastomotic site exceeds the resistance created by sutures, staples, and early scars. It may be possible to avoid anastomotic leakage by covering and reinforcing the anastomotic site with a biocompatible material. The aim of this study was to evaluate the safety and feasibility of a novel external reinforcement device for gastrointestinal anastomosis in an experimental model. METHODS A single pig was used in this non-survival study, and end-to-end anastomoses were created in six small bowel loops by a single-stapling technique using a circular stapler. Three of the six anastomoses were covered with a novel external reinforcement device. Air was injected, a pressure test of each anastomosis was performed, and the bursting pressure was measured. RESULTS Reinforcement of the anastomotic site with the device was successfully performed in all anastomoses. The bursting pressure was 76.1 ± 5.7 mmHg in the control group, and 126.8 ± 6.8 mmHg in the device group, respectively. The bursting pressure in the device group was significantly higher than that in the control group (p = 0.0006). CONCLUSIONS The novel external reinforcement device was safe and feasible for reinforcing the anastomoses in the experimental model.

Abstract
BACKGROUND Alvimopan is a µ-opioid receptor antagonist associated with shorter time to gastrointestinal recovery in patients having open colorectal surgery. Data demonstrating the benefit of perioperative alvimopan for the minimally invasive surgical approach are inconsistent. The aim of this study is to determine colorectal surgery groups that benefit from perioperative alvimopan. METHODS This is a retrospective cohort analysis of colorectal surgery patients who had, and patients who did not have, perioperative alvimopan in the Michigan Surgical Quality Collaborative regional risk-adjusted database from 2018 through 2021. Main outcome measures were postoperative length of hospital stay, time to return of bowel function, and postoperative ileus. RESULTS There were 10,010 patients (30.3% open, 40.5% laparoscopic, 12.7% hand-assist laparoscopic, 43.5% robotic) who met inclusion criteria-4919 received alvimopan in the perioperative period and 5091 did not. When compared to those not receiving alvimopan, unadjusted outcomes showed that the alvimopan group had significantly shorter postoperative length of stay (4.75 days vs 5.5 days, p < 0.001), shorter time to return of bowel function (1.61 days vs 2.01 days, p < 0.001) and less postoperative ileus (5.45% vs 7.94%, p < 0.001). After adjustment, regression models confirmed that alvimopan was associated with an 9.6% reduction in hospital length of stay (p < 0.001), a 14.9% shorter time to return of bowel function (p < 0.001), and a 42.1% reduction in postoperative ileus (p < 0.001). Subgroup analysis showed significant benefit of alvimopan for all three outcomes in patients having the minimally invasive approach. CONCLUSIONS Alvimopan is associated with shorter hospital length of stay, shorter time to return of bowel function, and decreased postoperative ileus when administered to patients undergoing colorectal surgery. Benefit is not limited to the open approach and includes minimally invasive laparoscopic and robotic colorectal procedures.

Abstract
BACKGROUND Enhanced recovery after surgery (ERAS) programs are well-established, resulting in improved outcomes and shorter length of hospital stay (LOS). Same-day discharge (SDD), or "hyper-ERAS", is a natural progression of ERAS. This systematic review aims to compare the safety and efficacy of SDD against conventional ERAS in colorectal surgery. METHODS The protocol was prospectively registered in PROSPERO (394793). A systematic search was performed in major databases to identify relevant articles, and a narrative systematic review was performed. Primary outcomes were readmission rates and length of hospital stay (LOS). Secondary outcomes were operative time and blood loss, postoperative pain, morbidity, nausea or vomiting, and patient satisfaction. Risks of bias was assessed using the ROBINS-I tool. RESULTS Thirteen studies were included, with five single-arm and eight comparative studies, of which one was a randomised controlled trial. This comprised a total of 38,854 patients (SDD: 1622; ERAS: 37,232). Of the 1622 patients on the SDD pathway, 1590 patients (98%) were successfully discharged within 24 h of surgery. While most studies had an overall low risk of bias, there was considerable variability in inclusion criteria, types of surgery or anaesthesia, and discharge criteria. SDD resulted in a significantly reduced postoperative LOS, without increasing risk of 30-day readmission. Intraoperative blood loss and postoperative morbidity rates were comparable between both groups. Operative duration was shorter in the SDD group. Patient-reported satisfaction was high in the SDD cohort. CONCLUSION SDD protocols appear to be safe and feasible in selected patients undergoing major colorectal operations. Randomised controlled trials are necessary to further substantiate these findings.

Abstract
INTRODUCTION AND OBJECTIVES Enhanced Recovery After Surgery (ERAS) is a multimodal strategy designed to optimize postoperative recovery and reduce morbidity, length of hospital stay, and care costs. The aim of this study was to evaluate compliance and clinical outcomes 6 months of implementation of the program in scheduled colorectal surgery in a tertiary hospital. MATERIAL AND METHODS Data from 209 patients who underwent elective colorectal surgery were analysed. The first 102 patients (pre-ERAS group) who underwent surgery between January and May 2018, before the implementation of the program, were compared with the 107 patients treated between May and October 2019, after ERAS implementation. The main outcomes were patient education and counselling, use of intravenous fluids, early mobilization, incidence of postoperative nausea and vomiting, return of bowel function, length of stay, complications, mortality, and overall compliance. RESULTS The ERAS program was associated with a significant increase in patient education and counselling (p<0.001) and with a significant reduction in intra- and postoperative IV fluid administration (p=0.007 and p<0.001, respectively) and postoperative nausea or vomiting (17.6% vs 5.0%, p=0.007). Time to recovery of activities of daily living (5.29 vs 2.85 days; p<0.001), time to solid oral intake (6.21 vs 4.35 days; p<0.001), time to first flatus (2.41 vs 1.51 days; p<0.001) and defecation (3.35 vs 1.66 days; p<0.001) decreased with ERAS. There were no statistically significant differences in length of stay, complications, and mortality. CONCLUSION This study showed that the ERAS program improved perioperative outcomes and postoperative recovery in patients undergoing colorectal surgery in our hospital.

Abstract
BACKGROUND Some studies have suggested disparities in access to robotic colorectal surgery, however, it is unclear which factors are most meaningful in the determination of approach relative to laparoscopic or open surgery. This study aimed to identify the most influential factors contributing to robotic colorectal surgery utilization. METHODS We conducted a systematic review and random-effects meta-analysis of published studies that compared the utilization of robotic colorectal surgery versus laparoscopic or open surgery. Eligible studies were identified through PubMed, EMBASE, CINAHL, Cochrane CENTRAL, PsycINFO, and ProQuest Dissertations in September 2021. RESULTS Twenty-nine studies were included in the analysis. Patients were less likely to undergo robotic versus laparoscopic surgery if they were female (OR = 0.91, 0.84-0.98), older (OR = 1.61, 1.38-1.88), had Medicare (OR = 0.84, 0.71-0.99), or had comorbidities (OR = 0.83, 0.77-0.91). Non-academic hospitals had lower odds of conducting robotic versus laparoscopic surgery (OR = 0.73, 0.62-0.86). Additional disparities were observed when comparing robotic with open surgery for patients who were Black (OR = 0.78, 0.71-0.86), had lower income (OR = 0.67, 0.62-0.74), had Medicaid (OR = 0.58, 0.43-0.80), or were uninsured (OR = 0.29, 0.21-0.39). CONCLUSION When determining who undergoes robotic surgery, consideration of factors such as age and comorbid conditions may be clinically justified, while other factors seem less justifiable. Black patients and the underinsured were less likely to undergo robotic surgery. This study identifies nonclinical disparities in access to robotics that should be addressed to provide more equitable access to innovations in colorectal surgery.

Abstract
INTRODUCTION Preoperative immuno-nutrition has been associated with reductions in infectious complications and length of stay, but remains unstudied in the setting of an enhanced recovery protocol. The objective was to evaluate outcomes after elective colorectal surgery with the addition of a preoperative immuno-nutrition supplement. METHODS In October 2017, all major colorectal surgeries were given an arginine-based supplement prior to surgery. The control group consisted of cases within the same enhanced recovery protocol from three years prior. The primary outcome was a composite of overall morbidity. Secondary outcomes were infectious complications and length of stay with subgroup analysis based on degrees of malnutrition. RESULTS Of 826 patients, 514 were given immuno-nutrition prospectively and no differences in complication rates (21.5% versus 23.9%, P = 0.416) or surgical site infections (SSIs) (6.4% versus 6.9%, P = 0.801) were observed. Hospitalization was slightly shorter in the immuno-nutrition cohort (5.0 [3.0, 7.0], versus 5.5 days [3.6, 7.9], P = 0.002). There was a clinically insignificant difference in prognostic nutrition index scores between cohorts (35.2 ± 5.6 versus 36.1 ± 5.0, P = 0.021); however, subgroup analysis (< 33, 34-38 and > 38) failed to demonstrate an association with complications (P = 0.275) or SSIs (P = 0.640) and immuno-nutrition use. CONCLUSIONS Complication rates and SSIs were unchanged with the addition of immuno-nutrition before elective colorectal surgery. The association with length of stay is small and without clinical significance; therefore, the routine use of immuno-nutrition in this setting is of questionable benefit.

Abstract
Randomized research demonstrated that robotic surgery was oncologically safe and beneficial in the short term. We investigated whether older adults benefit from robotics more than younger adults do in terms of short-term outcomes. We identified all older (≥ 70 years old) and younger (≤ 70) adults with rectal cancer treated with resection between 2019 and 2022 from an institutional database. We assessed the short-term post-operative 90-day outcomes, which included the first bowel movement, length of hospital duration, sepsis, and harvested lymph node on an age-based differentiation. The key outcomes were complications and grades III-IV on the Clavien-Dindo scale. We identified 298 individuals treated with oncologic resection of rectal cancer: 108 (36.6%) were older adults, while 190 (63.4%) were younger adults. Older adults treated with robotic surgery include 45 (41.6%), whereas 63 (58.3%) older adults were treated with laparoscopic surgery, and 85 (44.7%) younger adults were treated with robotic surgery, while 105 (55.2%) younger adults were treated with laparoscopic surgery. The Clavien-Dindo grading system exposes a substantial P < 0.05 in younger group, whereas grade III-IV patients are seen more frequently in laparoscopic surgery than robotic surgery. Younger and older persons both benefited differently from robotic surgery when compared to laparoscopic surgery in terms of major post-operative complications.

Abstract
BACKGROUND Colorectal cancer is a leading cause of morbidity and mortality across U.S. racial/ethnic groups. Existing studies often focus on a particular race/ethnicity or single domain within the care continuum. Granular exploration of disparities among different racial/ethnic groups across the entire colon cancer care continuum is needed. We aimed to characterize differences in colon cancer outcomes by race/ethnicity across each stage of the care continuum. METHODS We used the 2010-2017 National Cancer Database to examine differences in outcomes by race/ethnicity across six domains: clinical stage at presentation; timing of surgery; access to minimally invasive surgery; post-operative outcomes; utilization of chemotherapy; and cumulative incidence of death. Analysis was via multivariable logistic or median regression, with select demographics, hospital factors, and treatment details as covariates. RESULTS 326,003 patients (49.6% female, 24.0% non-White, including 12.7% Black, 6.1% Hispanic/Spanish, 1.3% East Asian, 0.9% Southeast Asian, 0.4% South Asian, 0.3% AIAE, and 0.2% NHOPI) met inclusion criteria. Relative to non-Hispanic White patients: Southeast Asian (OR 1.39, p < 0.01), Hispanic/Spanish (OR 1.11 p < 0.01), and Black (OR 1.09, p < 0.01) patients had increased odds of presenting with advanced clinical stage. Southeast Asian (OR 1.37, p < 0.01), East Asian (OR 1.27, p = 0.05), Hispanic/Spanish (OR 1.05 p = 0.02), and Black (OR 1.05, p < 0.01) patients had increased odds of advanced pathologic stage. Black patients had increased odds of experiencing a surgical delay (OR 1.33, p < 0.01); receiving non-robotic surgery (OR 1.12, p < 0.01); having post-surgical complications (OR 1.29, p < 0.01); initiating chemotherapy more than 90 days post-surgery (OR 1.24, p < 0.01); and omitting chemotherapy altogether (OR 1.12, p = 0.05). Black patients had significantly higher cumulative incidence of death at every pathologic stage relative to non-Hispanic White patients when adjusting for non-modifiable patient factors (p < 0.05, all stages), but these differences were no longer statistically significant when also adjusting for modifiable factors such as insurance status and income. CONCLUSIONS Non-White patients disproportionately experience advanced stage at presentation. Disparities for Black patients are seen across the entire colon cancer care continuum. Targeted interventions may be appropriate for some groups; however, major system-level transformation is needed to address disparities experienced by Black patients.

Abstract
PURPOSE In Germany, colorectal robot-assisted surgery (RAS) has found its way and is currently used as primary technique in colorectal resections at our clinic. We investigated whether RAS can be extensively combined with enhanced recovery after surgery (ERAS®) in a large prospective patient group. METHODS Using the DaVinci Xi surgical robot, all colorectal RAS from 09/2020 to 01/2022 were incorporated into our ERAS® program. Perioperative data were prospectively recorded using a data documentation system. The extent of resection, duration of the operation, intraoperative blood loss, conversion rate, and postoperative short-term results were analyzed. We documented the postoperative duration of Intermediate Care Unit (IMC) stay and major and minor complications according to the Clavien-Dindo classification, anastomotic leak rate, reoperation rate, hospital-stay length, and ERAS® guideline adherence. RESULTS One hundred patients (65 colon and 35 rectal resections) were included (median age: 69 years). The median durations of surgery were 167 min (colon resection) and 246 min (rectal resection). Postoperatively, four patients were IMC-treated (median stay: 1 day). In 92.5% of the colon and 88.6% of the rectum resections, no or minor complications occurred postoperatively. The anastomotic leak rate was 3.1% in colon and 5.7% in rectal resection. The reoperation rate was 7.7% (colon resection) and 11.4% (rectal resection). The hospital stay length was 5 days (colon resection) and 6.5 days (rectal resection). The ERAS® guideline adherence rate was 88% (colon resection) and 82.6% (rectal resection). CONCLUSION Patient perioperative therapy per the multimodal ERAS® concept is possible without any problems in colorectal RAS, leading to low morbidity and short hospital stays.

Abstract
PURPOSE Even though minor, stoma-related complications significantly impact quality of life, they are often excluded from clinical analyses that compare short-term postoperative outcomes of loop ileostomy and loop colostomy. This study compares stoma-related complications between loop ileostomy and loop colostomy after rectal resection, including minor complications, and discusses the characteristics of diverting stoma types. METHODS A retrospective review was conducted in patients who underwent diverting stoma construction after rectal resection. Data on patient background and postoperative short-term outcomes, including stoma-related complications and morbidity after stoma closure, were collected and compared between loop ileostomy and loop colostomy groups. Morbidities of all severity grades were targeted for analysis. RESULTS A total of 47 patients (27 loop ileostomy, 20 loop colostomy) underwent diverting stoma construction following rectal resection. Overall stoma-related complications, incidence of skin irritation, high-output stoma, and outlet obstruction were significantly higher in the loop ileostomy group but high-output stoma and outlet obstruction were absent in the loop colostomy group. Regarding morbidity after stoma closure, operation times and surgical site infections were significantly higher in the loop colostomy group while anastomotic leakage after diverting stoma closure occurred (2 cases; 15%) in the loop colostomy group but not the loop ileostomy group. CONCLUSION Because stoma-related complications were significantly higher in the loop ileostomy group, and even these minor complications may impair QOL, early loop ileostomy closure is recommended. For loop colostomy, stoma-related morbidities are lower but post-closure leakage is a calculated risk.

Abstract
BACKGROUND The aim of this review was to explore the role of three-dimensional (3D) printing in colorectal surgical education and procedural simulation, and to assess the effectiveness of 3D-printed models in anatomic and operative education in colorectal surgery. METHODS A systematic review of the literature was performed following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines to identify relevant publications relating to the use of 3D-printed models in colorectal surgery in an educational context. The search encompassed OVID Medline, Web of Science and EMBASE including papers in English published from 1 January 1995 to 1 January 2023. A total of 1018 publications were screened, and 5 met the criteria for inclusion in this review. RESULTS Four distinct 3D models were described across five studies. Two models demonstrated objective benefits in the use of 3D-printed models in anatomical education in academic outcomes at all levels of learner medical experience and were well accepted by learners. One model utilised for preoperative visualisation demonstrated improved operative outcomes in complete mesocolic excision compared with preoperative imaging review, with a 22.1% reduction in operative time (p < 0.001), 9.2% reduction in surgical duration (p = 0.035) and 37.3% reduction in intraoperative bleeding volume amongst novice surgeons (p < 0.01). Technical simulation has been demonstrated in a feasibility context in one model but remains limited in scope and application on account of the characteristics of available printing materials. CONCLUSIONS 3D printing is well accepted and effective for anatomic education and preoperative procedural planning amongst colorectal surgeons, trainees and medical students but remains a technology in the early stages of its possible application. Technological advancements are required to improve the tissue realism of 3D-printed organ models to achieve greater fidelity and provide realistic colorectal surgical simulations.

Abstract
INTRODUCTION Emergent surgery for colorectal cancer (CRC) is associated with higher rates of morbidity and mortality and outcomes differ by surgical approach. METHODS Our study compares short-term surgical outcomes of patients undergoing emergent colectomy for CRC using the open vs minimally invasive (MIS) approach. We performed a four-year review (2012-2015) of the ACS-NSQIP Colectomy dataset and included all adult patients with CRC who underwent emergent surgical intervention. Patients were stratified into groups based on surgical approach: Open and MIS (including laparoscopic and robotic). RESULTS A total of 1855 (MIS: 279, Open: 1576) patients were included. Outcome measures were operative time, 30-day complications, 30-day readmission, and 30-day mortality. Multivariate Regression analysis was performed. Patients in the open group were more likely to be older (70y vs. 61y, p < 0.01), have higher ASA class, and were less likely to have received mechanical bowel preparation. On univariate analysis, patients in the MIS group had longer operative time (189 ± 41 min vs. 161 ± 69 min, p < 0.01). Patients in the open group had higher rates of mortality (6.7% vs. 3.8%, p < 0.01) and 30-day complications (28.1% vs. 16.7%, p < 0.01). On regression analysis, the open approach was independently associated with higher odds of 30-day mortality and 30-day complications. CONCLUSION Given the lower overall mortality and complications, MIS colectomy may be a safer approach in the emergent treatment of patients with colorectal cancer.

Abstract
In colorectal surgery, anastomotic leakage is a serious complication, leading to higher postoperative morbidity and mortality. The aim of this study was to evaluate the accuracy of serum and intraperitoneal C-reactive protein (CRP) in early diagnostics of anastomotic leakage on the first four postoperative days after colorectal surgery. From January to October 2019, fifty-nine patients with colorectal carcinoma were operated on, with formation of primary anastomosis. Anastomotic leakage was diagnosed in eight patients. Comparing the levels of serum and intraperitoneal CRP, our study showed that serum CRP was a better predictor of anastomotic leakage. Serum CRP levels lower than 121 mg/L on postoperative day 4 were predictive of good healing of anastomosis.

Abstract
PURPOSE This study compares the cost-effectiveness of open, laparoscopic (LAP), laparoscopic-assisted (LAPA), hand-assisted laparoscopic (HAL), and robotic colorectal surgery using a network meta-analysis. METHODS Randomized clinical trials (RCTs) evaluating the cost-effectiveness of comparing the five different approaches in colorectal surgery were included in a literature search until September 2022. Bayesian network meta-analysis was conducted, and surface under cumulative ranking area (SUCRA) values, odds ratio (OR), and 95% credible intervals (CrIs) were reported for total costs, surgical costs, operating time, length of stay (LOS), and postoperative outcomes. Cluster analysis was performed to examine the similarity and classification of surgical approaches into homogeneous clusters. The cophenetic correlation coefficient (cc) was evaluated to identify the most cost-effective clustering method. The primary outcomes assessed were: costs-morbidity, costs-mortality, and costs-efficacy, measuring total costs against postoperative complications, mortality rate, and LOS, respectively. RESULTS 22 RCTs with 4239 patients were included. Open surgery had the lowest total costs, surgical costs, and operating time but the longest LOS and most postoperative complications. LOS was significantly decreased in LAP compared to open surgery (OR 0.67, 95% CrI 0.46-0.96). Robotic surgery resulted in the highest total costs, surgical costs, and most extended operative duration but the shortest LOS and lowest mortality. LAPA and robotic surgery were superior in the costs-morbidity analysis. HAL was associated with the worst costs-mortality profile. LAP, LAPA, and HAL were better in terms of costs-efficacy. CONCLUSION Overall, LAP and LAPA are the most cost-effective approaches for colorectal surgery in terms of overall postoperative complications, mortality, and LOS.
