RESUMEN
This video vignette illustrates the application of the da Vinci Xi® robotic platform for robotic left colectomy and intracorporeal overlap anastomosis in a 51-year-old patient diagnosed with sigmoid-descending colon junction cancer. Emphasizing the advantages of robotic surgery in colorectal procedures, the video showcases a complete mesocolic excision, involving steps such as medial-to-lateral dissection, mobilization of the splenic flexure, ligation of the left colic and sigmoid arteries, and resection of an abdominal wall nodule. The presentation highlights the surgical precision and efficiency achieved, including minimal blood loss and no complications, with an operation time of 190 min. The postoperative outcome was favorable, with the patient discharged on the eighth day and subsequent management involving chemotherapy and hyperthermic intraperitoneal chemotherapy (HIPEC) for stage pT4bN1aM1c moderately differentiated adenocarcinoma. This case underscores the enhanced capabilities of robotic platforms in complex colorectal surgeries, particularly in achieving cytoreductive surgery (CRS) and ensuring anastomosis safety with improved R0 resection rates.

PURPOSE: Performing intracorporeal anastomoses in minimally invasive colon surgery appears to provide better short-term outcomes for patients with colon cancer. The aim of the study is to compare surgical aspects and short-term outcomes between intracorporeal and extracorporeal techniques in left colectomies with both laparoscopic and robotic approaches and evaluate advantages and disadvantages of intracorporeal anastomosis according to IDEAL framework (Exploration, stage 2b). METHODS: This is a single center, ambispective cohort study comparing total intracorporeal anastomosis (TIA) and standard surgery with extracorporeal anastomosis (EA). Patients with colon cancer treated by left colectomy, sigmoidectomy and high anterior resection by total intracorporeal anastomosis between May 2020 and January 2023 without exclusion criteria were prospectively included in a standardized database. Short-term outcomes in the group undergoing TIA were compared with a historical EA cohort. The main assessment outcomes were intraoperative complications, postoperative morbidity according to the Clavien-Dindo scale and the comparison of pathological. We conducted a preliminary comparative study within the TIA group between approaches, a primary analysis between the two anastomotic techniques, and a propensity score matched analysis including only the laparoscopic approach, between both anastomotic techniques. RESULTS: Two hundred and forty-six patients were included: 103 who underwent TIA, 35 of them with laparoscopic approach and 68 with robotic approach, and a comparison group comprising another 103 eligible consecutive patients who underwent laparoscopic EA. There were no statistically significant differences between the two groups in terms of demographic variables. No statistically significant differences were observed in anastomotic dehiscence. Intraoperative complications are fewer in the TIA group, with a higher C-Reactive Protein levels. Relevant anastomotic bleeding and the number of retrieved lymph nodes were higher in EA group. Nevertheless, no differences were observed in terms of overall morbidity. CONCLUSION: Minimally invasive left colectomy with intracorporeal resection and anastomosis is technically feasible and safe suing either a laparoscopic or a robotic approach. Clinical data from this cohort demonstrate outcomes comparable to those achieved through the conventional EA procedure in relation to postoperative morbidity and oncological efficacy, with indications suggesting that the utilization of robotic-assisted techniques may play a contributing role in enhancing overall treatment outcomes.

PURPOSE: Since the literature currently provides controversial data on the postoperative outcomes following right and left hemicolectomies, we carried out this study to examine the short- and long-term treatment outcomes. METHODS: This study included consecutive patients who underwent right or left-sided colonic resections from year 2014 to 2018 and then they were followed up. The short-term outcomes such as postoperative morbidity and mortality according to Clavien-Dindo score, duration of hospital stay, and 90-day readmission rate were evaluated as well as long-term outcomes of overall survival and disease-free survival. Multivariable Cox regression analysis was performed of overall and progression-free survival. RESULTS: In total, 1107 patients with colon tumors were included in the study, 525 patients with right-sided tumors (RCC) and 582 cases with tumors in the left part of the colon (LCC). RCC group patients were older (P < 0.001), with a higher ASA score (P < 0.001), and with more cardiovascular comorbidities (P < 0.001). No differences were observed between groups in terms of postoperative outcomes such as morbidity and mortality, except 90-day readmission which was more frequent in the RCC group. Upon histopathological analysis, the RCC group's patients had more removed lymph nodes (29 ± 14 vs 20 ± 11, P = 0.001) and more locally progressed (pT3-4) tumors (85.4% versus 73.4%, P = 0.001). Significantly greater 5-year overall survival and disease-free survival (P = 0.001) were observed for patients in the LCC group, according to univariate Kaplan-Meier analysis. CONCLUSIONS: Patients with right-sided colon cancer were older and had more advanced disease. Short-term surgical outcomes were similar, but patients in the LCC group resulted in better long-term outcomes.

AIM: The use of robot-assisted surgery for left-sided colon cancer is increasing in Denmark; however, it is yet to be established if the robotic approach results in improved clinical outcomes compared with the corresponding laparoscopic approach. The aim of this study was to compare the intraoperative and short-term postoperative outcomes of robot-assisted surgery with laparoscopic surgery for left-sided colon cancer at a national level. METHOD: The study is a nationwide database study based on data from the Danish Colorectal Cancer Group database. Patients from all colorectal centres in Denmark treated with surgery with curative intent in an elective setting with either robotic or laparoscopic left colectomy or sigmoidectomy during the period 2014-2019 were included. To adjust for confounding, propensity score matching (PSM) was performed and the groups were compared for age, sex, body mass index, American Society of Anesthesiologists classification, performance score, year of diagnosis, neoadjuvant chemotherapy, left colectomy or sigmoidectomy, tumour localization, use of stoma or stenting and pathological T (pT) category. RESULTS: A total of 5532 patients were available for analysis, and after PSM in a ratio of 2:1, 1392 laparoscopic and 696 robotic cases were identified. After matching we found a lower conversion rate and a higher lymph node yield in the robotic group compared with the laparoscopic group (5.8% vs. 11%, p < 0.001 and 27 vs. 24, p < 0.001, respectively). Further, we found a higher proportion of patients with a lymph node yield of 12 or more in the robotic group (97% vs. 94.8%, p = 0.02). Plane of dissection, radicality and pathological disease stages did not differ between the two groups. We found no difference in either overall surgical (13% vs. 11.1%, p = 0.23) or medical (5.6% vs. 6.5%, p = 0.49) postoperative complications and no difference in 30-day (p = 0.369) or 90-day mortality (p = 0.08). CONCLUSION: Robot-assisted surgery for left-sided colon cancer was associated with a significantly lower conversion rate and a significantly higher lymph node yield than the laparoscopic approach. Postoperative morbidity and mortality were similar in the two groups.

PURPOSE: The purpose of this study was to investigate the effect of laparoscopic left colectomy (LLC) and laparoscopic sigmoidectomy (LSD) on short-term outcomes and prognosis of sigmoid colon cancer (SCC) patients using propensity score matching (PSM). METHODS: In this retrospective study, the SCC patients who underwent LLC or LSD surgery were collected from a single clinical center from Jan 2011 to Dec 2019. Short-term outcomes and prognosis were compared between patients who received LSD surgery and LLC surgery. RESULTS: A total of 356 patients were included in this study. After 1:1 PSM analysis, there were 50 patients who underwent LLC surgery and 50 patients who underwent LSD surgery left in this study. No significant difference was found in baseline characteristics after PSM (P > .05). In comparison with the LLC surgery group, the LSD surgery group had shorter operation time (P = .003) after PSM. Moreover, the surgical procedure was not an independent predictor for overall survival (OS) (P = .918, 95% CI = .333-2.688) and disease-free survival DFS (P = .730, 95% CI = .335-2.150), but age (OS: P = .009, 95% CI = 1.010-1.075; DFS: P = .014, 95% CI = 1.007-1.061) and tumor stage (OS: P = .004, 95% CI = 1.302-3.844; DFS: P < .01, 95% CI = 1.572-4.171) were the independent risk factors for OS and DFS in SCC patients. CONCLUSION: There was no significant difference between the two surgical procedures for prognosis of SCC patients. However, the possible reasons for changing the surgical procedures should be cautious by surgeons.

PURPOSE: The primary aim was to investigate the operative outcomes of intracorporeal (IA) and extracorporeal (EA) anastomosis in left-sided minimally-invasive colectomy. METHODS: A comprehensive literature search was conducted for studies comparing operative outcomes and follow-up data of IA versus EA in minimally-invasive left colectomy. Studies that investigated recto-sigmoid resections using transanal circular staplers were excluded. Data from eligible studies were extracted, qualitatively assessed, and included in a meta-analysis. Odds ratios (ORs) and mean differences with 95 per cent confidence intervals were calculated. RESULTS: Eight studies with a total of 750 patients were included (IA n = 335 versus EA n = 415). IA was associated with significantly lower overall morbidity (OR 0.40, 95% CI 0.26-0.61, p < 0.0001) and less frequent surgical site infection (SSI) (OR 0.27, 95% CI 0.12-0.61, p = 0.002) as primary outcomes compared to EA. Of the secondary outcomes, length of incision (SMD -2.51, 95% CI -4.21 to -0.81, p = 0.004), time to first oral diet intake (SMD -0.49, 95% CI -0.76 to -0.22, p = 0. 0004) and time to first bowel movement (SMD -0.40, 95% CI -0.71 to -0.09, p = 0.01) were significantly in favor of IA, while operative time was significantly shorter in the EA group (SMD 0.36, 95% CI 0.14-0.59, p = 0.001). CONCLUSIONS: IA proves to be a safe and feasible option as it demonstrates benefits in terms of lower overall morbidity, fewer rates of SSI, smaller incision length, and faster postoperative gastrointestinal recovery despite a longer operative time compared to EA.

Introducción: El sangrado digestivo intraluminal postoperatorio es una entidad poco frecuente y su manifestación clínica no difiere de la hemorragia digestiva baja de otra etiología. A pesar de que su presentación más habitual es la hematoquecia autolimitada en la primera deposición, en un discreto porcentaje puede requerir transfusiones, tratamiento endoscópico, hemodinámico, o incluso cirugía. Objetivo: Analizar los pacientes con sangrado digestivo intraluminal postoperatorio tratados en un centro de alta complejidad y realizar una revisión bibliográfica del tema. Diseño: Estudio retrospectivo, descriptivo. Material y métodos: Pacientes con sangrado anastomótico durante el post operatorio inmediato de una colectomía izquierda, operados en el Servicio de Cirugía General y Coloproctología desde enero del 2017 a diciembre del 2021. Las variables estudiadas fueron edad, sexo, anticoagulación y su causa, descenso de hemoglobina, cirugía realizada y su indicación, vía de abordaje, configuración de la anastomosis, electividad de la cirugía, complicaciones, días de internación y manejo terapéutico. Resultados: Se incluyeron 4 pacientes con una edad media de 72 (rango 54-87) años y una distribución por sexo de 1:1. En todos la colectomía izquierda fue programada y en 3 el abordaje fue laparoscópico. La anastomosis fue termino-terminal con sutura mecánica circular. Todos los pacientes presentaron sangrado en las primeras 24 horas postoperatorias. El tratamiento fue decidido de acuerdo a la condición hemodinámica: en los 2 pacientes con estabilidad hemodinámica fue suficiente el tratamiento conservador con reanimación y transfusiones. Los otros 2 que presentaron inestabilidad hemodinámica requirieron manejo intervencionista con endoscopía rígida, videocolonoscopía y cirugía. Conclusión: El sangrado intraluminal es una complicación poco frecuente de la anastomosis colorrectal que requiere manejo intervencionista solo en los pacientes que presentan inestabilidad hemodinámica.

Introduction: Postoperative intraluminal gastrointestinal bleeding is a rare entity and its clinical manifestation does not differ from lower gastro-intestinal bleeding of another etiology. Despite the fact that its most common presentation is self-limited hematochezia at the first stool, in a small percentage it may require transfusions, endoscopic or hemodynamic management, or even surgery. Aim: To analyze the patients with postoperative intraluminal gastrointestinal bleeding treated in a tertiary center and to carry out a bibliographic review of the subject. Design: Retrospective descriptive study. Material and methods: Patients with immediate postoperative anastomotic bleeding from a left colectomy, operated on at the General Surgery and Coloproctology Service from January 2017 to December 2021 were included. The variables recorded were age, sex, anticoagulation and its cause, decrease in hemoglobin, procedure performed and its indication, surgical approach, type of anastomosis, electiveness of surgery, complications, hospital stay and management. Results: Four patients with a mean age of 72 (range 54-87) years and a 1:1 gender distribution were included. All procedures were elective and 3 laparoscopic. All anastomoses were performed end-to-end with a circular stapler. All patients presented bleeding in the first 24 postoperative hours. The treatment was decided according to the hemodynamic condition; patients with hemodynamic stability (2) received medical treatment while those with hemodynamic instability (2) required interventional management with rigid endoscopy, colonoscopy and surgery. Conclusion: Intraluminal bleeding is a rare complication of colorectal anastomosis that requires interventional management only in patients with hemodynamic instability. (AU)

Vascular approach during elective laparoscopic left colectomy impacts post-operative outcomes. The aim of our study was to evaluate how different approaches impact positively defecatory, urinary and sexual functions and quality of life during elective laparoscopic left colectomy. A prospective non-randomized controlled trial at two tertiary center was conducted. All patients who underwent elective laparoscopic left colonic resection from January 2019 to July 2022 were analyzed. They were divided into two groups based on Inferior Mesenteric Artery (IMA) preservation with distal ligation of sigmoid branches close to a colonic wall for complicated diverticular disease and IMA high tie ligation for oncological disease. Patients were asked to fulfil standardized, validated questionnaires to evaluate pre and post-operative defecatory, urinary and sexual functions and quality of life. Defecatory disorders were assessed by high-resolution anorectal manometry preoperatively and six months after surgery. A total of 122 patients were included in the study. The 62 patients with IMA preservation showed a lower incidence of defecatory disorders also confirmed by manometer data, minor incontinence and less lifestyle alteration than the 60 patients with IMA high tie ligation. No urinary disorders such as incomplete emptying, frequency, intermittence or urgency were highlighted after surgery in the IMA preservation group. Evidence of any sexual disorders remained controversial. The IMA-preserving vascular approach seems to be an effective strategy to prevent postoperative functional disorders. It is a safe and feasible technique especially for diverticular disease. New prospective randomized and highly probative studies are needed to confirm the effectiveness in specific clinical situations.

Previous studies comparing right and left colectomies have shown variable short-term outcomes. Despite the rapid adoption of robotics in colorectal operations, few studies have addressed outcome differences between robotic right (RRC) and left (RLC) colectomies. Therefore, we sought to compare the short-term outcomes of RRC and RLC for neoplasia. This is a systematic review and meta-analysis of articles published from the time of inception of the datasets to May 1, 2022. The electronic databases included English publications in Ovid MEDLINE In-Process and Other Non-Indexed Citations, Ovid MEDLINE, Ovid EMBASE, and Scopus. A total of 13,514 patients with colon neoplasia enrolled in 9 comparative studies were included. The overall mean age was 64.1 years (standard deviation [SD] ± 9.8), and there was a minor female predominance (52% female vs. 48% male). 8656 (64.0%) underwent RRC and 4858 (36.0%) underwent RLC. The ASA score 1 of - 2 in the LRC group was 37% vs. 21% in the R. Whereas the ASA score 3-4 was 62% in the LRC vs. 76% in RRC. Moreover, the mean of the Charlson Comorbidity Score in the LRC was 4.3 (SD 1.9) vs. 3.1 (SD 2.3) in the RRC. Meta-analysis revealed a significantly higher rate of ileus in RRC (10%) compared to RLC (7%) (OR 1.46, 95% CI 1.27-1.67). Additionally, operative time was significantly shorter by 22.6 min in RRC versus LRC (95% CI - 37.4-7.8; p < 0.001). There were no statistically significant differences between RRC and RLC in conversion to open operation, estimated blood loss, wound infection, anastomotic leak, reoperation, readmission, and hospital length of stay. In this only meta-analysis comparing RRC and LRC for colon neoplasia, we found that RRC was independently associated with a shorter operative time but increased risk of ileus.

BACKGROUND: Intracorporeal anastomosis (IA) is associated with reduced surgical site infection (SSI) and other postoperative complications in laparoscopic right colectomy (LRC). However, evidence is inadequate for IA in laparoscopic left colectomy (LLC). This study aimed to determine the effect of IA and extracorporeal anastomosis (EA) on SSI and other short-term postoperative complications in LLC. METHODS: In this retrospective multicenter propensity score-matched (PSM) cohort study, we enrolled consecutive patients who underwent LLC with IA (TLLC/IA) and laparoscopic-assisted left colectomy with EA (LALC/EA) at two medical centers between January 2015 and September 2021. Propensity score matching with a 1:2 ratio was employed. The primary outcome was SSI occurrence. Secondary outcomes were operating time, intraoperative hemorrhage, other postoperative complications, and pathological outcomes. RESULTS: Overall, 574 and 99 patients received LALC/EA and TLLC/IA, respectively. After PSM, 84 patients with TLLC/IA were matched with 141 patients with LALC/EA. Thirty patients (13.3%) patients experienced SSI (17.0% in LALC/EA vs 7.1% in TLLC/IA). IA was associated with a reduced risk of overall SSI and superficial/deep SSI compared with EA after PSM, with OR of 0.375 (95% CI, 0.147-0.959, P = 0.041). and 0.148 (95% CI, 0.034-0.648, P = 0.011), respectively. Multivariate analysis of unmatched patients indicated similar results. In the analysis of secondary outcomes, LALC/EA may have a shorter operating time (absolute mean difference - 13.41 [95% CI, - 23.76 to - 3.06], P = 0.002) and a higher risk of intraoperative hemorrhage (absolute risk difference 4.96 [95% CI, - 0.09 to 9.89], P = 0.048). CONCLUSIONS: IA in LLC is associated with a reduced risk of overall SSI and superficial/deep SSI. However, it may require a longer operating time.

PURPOSE: Robotic surgery for right-sided colon and rectal cancer has rapidly increased; however, there is limited evidence in the literature of advantages of robotic left colectomy (RLC) for left-sided colon cancer. The purpose of this study was to compare the outcomes of RLC versus laparoscopic left colectomy (LLC) with complete mesocolic excision (CME) for left-sided colon cancer. METHODS: Patients who had RLC or LLC with CME for left-sided colon cancer at five hospitals in China between January 2014 and April 2022 were included. A one-to-one propensity score matched analysis was performed to decrease confounding. The primary outcome was postoperative complications occurring within 30 days of surgery. Secondary outcomes were disease-free survival, overall survival and the number of harvested lymph nodes. RESULTS: A total of 292 patients (187 male; median age 61.0 [20.0-85.0] years) were eligible for this study, and propensity score matching yielded 102 patients in each group. The clinicopathological characteristics were well-matched between groups. The two groups did not differ in estimated blood loss, conversion to open rate, time to first flatus, reoperation rate, or postoperative length of hospital stay (p > 0.05). RLC was associated with a longer operation time (192.9 ± 53.2 vs. 168.9 ± 52.8 min, p = 0.001). The incidence of postoperative complications did not differ between the RLC and LLC groups (18.6% vs. 17.6%, p = 0.856). The total number of lymph nodes harvested in the RLC group was higher than that in the LLC group (15.7 ± 8.3 vs. 12.1 ± 5.9, p < 0.001). There were no significant differences in 3-year and 5-year overall survival or 3-year and 5-year disease-free survival. CONCLUSION: Compared to laparoscopic surgery, RLC with CME for left-sided colon cancer was found to be associated with higher numbers of lymph nodes harvested and similar postoperative complications and long-term survival outcomes.

The diffusion of robotic surgery is rapidly and constantly growing in different surgical specialties. Recently, novel robotic platforms have entered into the market. To date, however, most of the reports on their clinical use have specifically focused on gynecological and urological surgery. In this study, we present the first three robotic-assisted colectomies performed with the new Hugo RAS system (Medtronic, Minneapolis, MN, USA). The surgical team had previous robotic experience and completed simulation training and an official 2-day cadaver laboratory session. Operating room setting and trocar layout were planned and two full cadaver procedures were carried out (right and left colectomy). Onsite dry-run sessions were performed before tackling clinical cases. Three patients underwent robotic-assisted colectomies: one left colectomy, two right colectomies with complete mesocolic excision (CME) and high vascular ligation (HVL) at our Institution. Preoperative diagnosis was colonic adenocarcinoma in all cases. A description of the operative room setup, robotic arm configuration and docking angles is provided. Mean docking time and console time were 8 and 259 min, respectively. All the surgical steps were completed without critical surgical errors or high-priority alarms. Neither intraoperative complications nor conversions to open surgery were recorded. Postoperative courses were uneventful with a mean length of stay of 5 days. Further clinical data and experience are required for procedural standardization and potential integration of the system into robotic general surgery and colorectal programs.

BACKGROUND: As one of the 8 Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) Masters Program clinical pathways, the Colorectal Pathway aims to deliver educational content for the general surgeon organized along 3 levels of performance (competency, proficiency and mastery) each represented by an anchoring procedure. In this article, the SAGES Colorectal Task Force presents focused summaries of the top 10 seminal articles selected for laparoscopic left/sigmoid colectomy for uncomplicated disease. METHODS: Using a systematic literature search of Web of Science, the most cited articles on laparoscopic left and sigmoid colectomy were identified, reviewed, and ranked by members of the SAGES Colorectal Task Force. Additional articles not identified in the literature search were included if deemed impactful by expert consensus. The top 10 ranked articles were then summarized, including their findings, strengths and limitations with emphasis on relevance and impact in the field. RESULTS: The top 10 articles selected focus on variations in minimally invasive surgical techniques, video demonstrations, stratified approaches for benign and malignant disease as well as assessments of the learning curve. CONCLUSIONS: The selected top 10 seminal articles for laparoscopic left and sigmoid colectomy in uncomplicated disease are considered by the SAGES colorectal task force to be fundamental to the knowledge base of minimally invasive surgeons as they progress to mastery in these procedures.

BACKGROUND: The SAGES University Colorectal Masters Program is a structured educational curriculum that is designed to aid practicing surgeons develop and maintain knowledge and technical skills for laparoscopic colorectal surgery. The Colorectal Pathway is based on three anchoring procedures (laparoscopic right colectomy, laparoscopic left and sigmoid colectomy for uncomplicated and complex disease, and intracorporeal anastomosis for minimally invasive right colectomy) corresponding to three levels of performance (competency, proficiency and mastery). This manuscript presents focused summaries of the top 10 seminal articles selected for laparoscopic left and sigmoid colectomy for complex benign and malignant disease. METHODS: A systematic literature search of Web of Science for the most cited articles on the topic of laparoscopic complex left/sigmoid colectomy yielded 30 citations. These articles were reviewed and ranked by the SAGES Colorectal Task Force and invited subject experts according to their citation index. The top 10 ranked articles were then reviewed and summarized, with emphasis on relevance and impact in the field, study findings, strength and limitations and conclusions. RESULTS: The top 10 seminal articles selected for the laparoscopic left/sigmoid colectomy for complex disease anchoring procedure include advanced procedures such as minimally invasive splenic flexure mobilization techniques, laparoscopic surgery for complicated and/or diverticulitis, splenic flexure tumors, complete mesocolic excision, and other techniques (e.g., Deloyers or colonic transposition in cases with limited colonic reach after extended left-sided resection). CONCLUSIONS: The SAGES Colorectal Masters Program top 10 seminal articles selected for laparoscopic left and sigmoid colectomy for complex benign and malignant disease anchoring procedure are presented. These procedures were the most essential in the armamentarium of practicing surgeons that perform minimally invasive surgery for complex left and sigmoid colon pathology.

BACKGROUND: The optimal surgical treatment approach for splenic flexure colon cancers remains controversial regarding the type of resection. METHODS: We hypothesized that both extended and segmental resections have similar surgical and oncologic outcomes. A retrospective review of prospectively collected database was performed on all patients who had colectomy for splenic flexure colon cancer between 1996 and 2018. RESULTS: Of 142 patients, 119 underwent extended resection; therefore, this group was compared with the group which underwent segmental resection (n = 23). The groups were similar in age, sex, ASA scores, operative times, estimated blood loss, hospital length of stay, and postoperative complication rates (p > 0.05). Median follow-up was 9.58 years (IQR:5.46-16.48). Multivariable regression models demonstrated no significant association between resection approach and disease-free survival (HR 1.63 [95%CI:0.91-2.92]), as well as overall survival (HR 1.80 [95%CI:0.97; 3.36]). CONCLUSION: In the treatment of splenic flexure colon cancer, segmental colon resections have similar oncologic outcomes when compared to extended colectomies.

BACKGROUND: Hartmann's reversal (HR) is associated with significant technical complexity and morbidity. The decision to perform HR is difficult and up to 50% of patients with colostomies do not undergo a reversal. To better guide surgeons and patients with this decision, we sought to assess the surgical risks and outcomes of HR as compared to elective left colectomy (LC). METHODS: We conducted a retrospective analysis of a prospective database at a tertiary medical center. Patients undergoing elective Hartmann's reversal and left colectomy between January 2014 and November 2021 were identified. We compared preoperative variables, intraoperative events, and short-term postoperative outcomes. RESULTS: 135 patients were identified: 30 HR and 105 LC. There were no significant differences in demographics or preoperative comorbidities between HR and LC. There were more open and fewer robotic cases in HR (23.3% vs 2.9%, P < .0001; 46.6% vs 76.0%, P < .01). Total operative time was significantly longer in HR than LC (261.8 vs 211.7 minutes, P = .02). There was a significantly higher percentage of intraoperative complications in HR (13.3% vs 1.9%, P < .01). There was a significantly higher rate of minor postoperative complications in HR than LC (46.7% vs 26.7%, P = .04), but not major (6.7% vs 5.8%, P = .85). Time to first flatus/bowel movement was significantly longer in HR than LC (3.6 vs 2.5 days, P < .001). CONCLUSION: Hartmann's reversal is a more technically challenging operation than elective left colectomy and is associated with significantly higher rates of intraoperative and minor postoperative complications. Future studies should focus on mitigating these risk factors to optimize patient outcomes.

BACKGROUND: Robotic surgery has been widely used in the radical treatment of colonic cancer. However, it is unclear what advantages the robotic approach offers over other approaches in left colectomy. This study aims to explore the advantage of robotic surgery in left colectomy by comparing open, laparoscopic, and robotic surgery. METHODS: A retrospective analysis was performed on the clinical data of patients with radical left colectomy for colon cancer who were admitted to the Department of General Surgery, The First Affiliated Hospital of Nanchang University, from November 2012 to November 2017. Two hundred eleven patients included were divided into the open surgery group (OS, n=49), laparoscopic surgery group (LS, n=92), and robotic surgery group (RS, n=70) according to surgical techniques. The clinicopathologic data were collected for clinical outcome assessment. Finally, the clinical value of RS in radical left colectomy was further evaluated by propensity score matching (PSM) analysis. RESULTS: Three groups were similar in demographics and clinical characteristics. Compared with OS, LS and RS groups had better intraoperative and perioperative clinical outcomes. Moreover, the RS group exhibited the minimum operative times, length of stay (LOS), and evaluated blood loss. LS and RS also exhibited less perioperative and postoperative long-term complications. Three groups showed similar postoperative pathological outcomes. The overall survival and disease-free survival were also similar among the three groups (all P > 0.05). Cox regression analysis showed surgical approach was not a prognostic factor for overall survival (P = 0.671) and disease-free survival (P = 0.776). PSM analysis of RS and LS by clinical characteristics showed RS showed shorter operation time (P < 0.001) and LOS for patients without complications (P = 0.005). However, no significant differences were found in perioperative and long-term postoperative complications, pathological outcomes, overall survival, and disease-free survival. CONCLUSIONS: Among three techniques for radical left colectomy, LS and RS had significant advantages over OS in short-term clinical outcomes, and no significant differences were found in overall, disease-free survival, local recurrence, and distant metastasis incidence. Moreover, RS shows better perioperative clinical outcomes but without compromising survival compared with LS.

BACKGROUND: Hartmann's reversal (HR) is associated with significant technical difficulty and morbidity. Using the ACS-NSQIP database, we assessed the outcomes of HR as compared to elective left colectomy (LC). METHODS: The 2016-2019 ACS-NSQIP datasets were queried to identify patients undergoing HR and elective LC. Patients' demographics, comorbidities, and short-term surgical outcomes were evaluated using both univariable and multivariable methods. RESULTS: The study included 7,632 HR cases and 29,162 LC cases. The HR group had more patients with ASA grade III (50% vs. 42.4%). HR had more open-operative cases (69.4 vs. 18.5%) and longer mean operative times (213 vs. 191 min) than LC. Postoperatively, the HR group had a longer mean hospital stay (5.5 vs. 4.1 days) and higher complication rate (18.3% vs. 10.3%). HR was associated with increased odds of having a concurrent ileostomy (OR 2.11), deep space/organ infection (OR 1.55), and at least one complication (OR 1.56). CONCLUSION: HR is a more challenging operation with patients who fared worse than their LC counterparts. Consideration should be given to alternatives of the index Hartmann's procedure.
