RESUMEN
PURPOSE: The purpose of this study was to explore whether metabolic syndrome (MetS) affects the prognosis of colorectal cancer (CRC) patients after primary surgery and to analyze the effect of the specific components of MetS on CRC prognosis. METHODS: The PubMed, Embase and Cochrane Library databases were searched from inception to July 29, 2021. Overall survival (OS) and disease-free survival (DFS) were compared between the MetS group and the non-MetS group. RESULTS: The studies included in the meta-analysis included 4773 patients. All seven studies compared OS between the two groups, and after pooling all hazard ratios (HRs), no significant difference was found between the MetS group and the non-MetS group (HR = 1.17, 95% CI = 0.91 to 1.49, P = 0.21). Four studies compared DFS between the MetS group and the non-MetS group after pooling all the HRs, and there was no difference between the MetS group and the non-MetS group (HR = 1.05, 95% CI = 0.74 to 1.49, P = 0.21). Among the specific components of MetS, high fasting plasma glucose levels (HR = 1.25, 95% CI = 1.00 to 1.58, P = 0.05) had a marginally significant association with poor OS. CONCLUSION: MetS may not affect the prognosis of CRC after primary surgery. However, high fasting plasma glucose levels might contribute to poor OS.

The current study aimed to evaluate the effect of bilirubin on the outcomes of colorectal cancer (CRC) in patients who underwent radical CRC surgery. The levels of serum bilirubin, including total bilirubin (TBil), direct bilirubin (DBil) and indirect bilirubin (IBil), were divided into higher groups and lower groups according to the median. Multivariate logistic regression was performed to analyze the independent predictors for overall complications and major complications. For TBil, the hospitalization time of the higher TBil group was longer than that of the lower TBil group (p = 0.014 < 0.05). For DBil, the higher DBil group had longer operation times (p < 0.01), more intraoperative bleeding (p < 0.01), longer hospital stays (p < 0.01), and higher rates of overall complications (p < 0.01) and major complications (p = 0.021 < 0.05) than the lower DBil group. For the IBil group, blood loss during operation (p < 0.01) and hospital stays (p = 0.041 < 0.05) in the higher IBil group were lower than those in the lower IBil group. In terms of complications, we found that DBil was an independent predictor for overall complications (p < 0.01, OR = 1.036, 95% CI = 1.014-1.058) and major complications (p = 0.043, HR= 1.355, 95% CI= 1.009-1.820). Higher preoperative DBil increase the risk of complications after primary CRC surgery.

PURPOSE: The purpose of this study was to compare the short-term outcomes between laparoscopic Hartmann reversal (LHR) and open Hartmann reversal (OHR) in patients who had undergone Hartmann surgery for colorectal cancer (CRC). METHODS: The patients who underwent Hartmann reversal (HR) at the First Affiliated Hospital of Chongqing Medical University from Jun 2013 to Jun 2022 were retrospectively enrolled. The LHR group and the OHR group were compared using propensity score matching (PSM) analysis. RESULTS: A total of 89 patients who underwent Hartmann reversal (HR) were enrolled in this study. There were 48 (53.9%) patients in the LHR group and 41 (46.1%) patients in the OHR group. After 1:1 ratio PSM, no difference in baseline information remained (p > 0.05). There was no significant difference in operation time, blood loss, postoperative hospital stay, and postoperative complications (p > 0.05) before and after PSM. In the multivariable logistic regression analysis, pre-operative albumin < 42.0 g/L was an independent risk factor (p = 0.013 < 0.05, OR = 0.248, 95% CI = 0.083-0.741) for the HR-related complications; however, LHR/OHR was not a predictive risk factor (p = 0.663, OR = 1.250, 95% CI = 0.500-3.122). CONCLUSION: Based on the current evidence, although there was no difference in short-term prognosis, LHR still had some advantages considering that it was less invasive to the patient.

PURPOSE: The current study aimed to explore the efficacy and safety of Enhanced Recovery after surgery (ERAS) in older patients undergoing colorectal surgery. METHODS: Three databases including PubMed, Embase, Medline, and the Cochrane Library were used for searching eligible studies on Jun 8th,2022. To evaluate the effect of ERAS, we focused on the short-term outcomes including postoperative complications and recovery. Subgroup analysis was also conducted for patients undergoing colorectal cancer (CRC) surgery. All the data processing and analyses were carried out by Stata (V.16.0) software. RESULTS: Finally, there were fourteen studies involving 5961 patients enrolled in this study. As for surgical outcomes, we found that the older group had more overall complications (OR = 1.41, I2 = 36.59%, 95% CI = 1.20 to 1.65, P = 0.00), more obstruction (OR = 1.462, I2 = 0.00%, 95% CI = 1.037 to 2.061, P = 0.0304), more respiratory complications (OR = 1.721, I2 = 0.00%, 95% CI = 1.177 to 2.515, P = 0.0051), more cardiovascular complications (OR = 3.361, I2 = 57.72%, 95% CI = 1.072 to 10.542, P = 0.0377), more urinary complications (OR = 1.639, I2 = 37.63%, 95% CI = 1.168 to 2.299, P = 0.0043), less readmission (OR = 0.662, I2 = 44.48%, 95% CI = 0.484 to 0.906, P = 0.0100), higher mortality (OR = 0.662, I2 = 44.48%, 95% CI = 0.484 to 0.906, P = 0.0100), and longer overall survival (OS) (HR = 1.21, I2 = 0.00%, 95% CI = 0.566 to 1.859, P = 0.0002)). Subgroup analysis also found that older CRC patients had a higher risk of overall complications (OR = 1.37, I2 = 37.51%, 95% CI = 1.06 to 1.78, P < 0.05). CONCLUSION: Although ERAS could accelerate postoperative recovery and reduce postoperative complications, older patients who received ERAS still had higher complication incidence than younger patients. Although the proportion of re-hospitalizations was lower and the OS was better, doctors could not rely too much on ERAS. More measures were needed to improve the outcomes of colorectal surgery in older patients.

PURPOSE: The purpose of this study was to investigate the predictive value of advanced lung cancer inflammation index (ALI) for short-term outcomes and prognosis of colorectal cancer (CRC) patients who underwent radical surgery. METHODS: CRC patients who underwent radical resection were included from Jan 2011 to Jan 2020 in our single clinical centre. Short-term outcomes, overall survival (OS), and disease-free survival (DFS) were compared in different groups. Cox analysis was conducted to identify independent risk factors for OS and DFS. RESULTS: A total of 4010 patients who underwent radical CRC surgery were enrolled in the current study. As a result, the low ALI group had longer operation time (p = 0.02), more intra-operative blood loss (p < 0.01), longer postoperative hospital stay (p < 0.01), and more overall complications (p < 0.01). Moreover, ALI (p < 0.01, OR = 0.679, 95% CI = 0.578-0.798) was an independent risk factor for overall complications. As for survival, the low ALI group had worse OS in all TNM stages (p < 0.01), stage II (p < 0.01) and stage III (p < 0.01). Similarly, the low ALI group had worse DFS in all TNM stages (p < 0.01), stage II (p < 0.01), and stage III (p < 0.01). In Cox analysis, ALI was an independent risk factors for OS (p < 0.01, HR = 0.707, 95% CI = 0.589-0.849) and DFS (p < 0.01, HR = 0.732, 95% CI = 0.622-0.861). CONCLUSION: Lower ALI was associated with more postoperative complications, worse OS, and DFS for CRC patients who underwent radical surgery. Furthermore, ALI was an independent risk factor for overall complications, OS, and DFS. Surgeons should pay close attention to patients with low ALI before surgery and make clinical strategies cautiously.

BACKGROUND: The advanced lung cancer inflammation index (ALI) is a comprehensive assessment indicator that can reflect inflammation and nutrition conditions. However, there are some controversies about whether ALI is an independent prognostic factor for gastrointestinal cancer patients undergoing surgical resection. Thus, we aimed to clarify its prognostic value and explore the potential mechanisms. METHODS: Four databases including PubMed, Embase, the Cochrane Library, and CNKI were used for searching eligible studies from inception to June 28, 2022. All gastrointestinal cancers, including colorectal cancer (CRC), gastric cancer (GC), esophageal cancer (EC), liver cancer, cholangiocarcinoma, and pancreatic cancer were enrolled for analysis. We focused on prognosis most in the current meta-analysis. Survival indicators, including overall survival (OS), disease-free survival (DFS), and cancer-special survival (CSS) were compared between the high ALI group and the low ALI group. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist was submitted as a supplementary document. RESULTS: We finally included fourteen studies involving 5091 patients in this meta-analysis. After pooling the hazard ratios (HRs) and 95% confidence intervals (CIs), ALI was found to be an independent prognostic factor for both OS (HR = 2.09, I2 = 92%, 95% CI = 1.53 to 2.85, P < 0.01), DFS (HR = 1.48, I2 = 83%, 95% CI = 1.18 to 1.87, P < 0.01), and CSS (HR = 1.28, I2 = 1%, 95% CI = 1.02 to 1.60, P = 0.03) in gastrointestinal cancer. After subgroup analysis, we found that ALI was still closely related to OS for CRC (HR = 2.26, I2 = 93%, 95% CI = 1.53 to 3.32, P < 0.01) and GC (HR = 1.51, I2 = 40%, 95% CI = 1.13 to 2.04, P = 0.006) patients. As for DFS, ALI also has a predictive value on the prognosis of CRC (HR = 1.54, I2 = 85%, 95% CI = 1.14 to 2.07, P = 0.005) and GC (HR = 1.37, I2 = 0%, 95% CI = 1.09 to 1.73, P = 0.007) patients. CONCLUSION: ALI affected gastrointestinal cancer patients in terms of OS, DFS, and CSS. Meanwhile, ALI was a prognostic factor both for CRC and GC patients after subgroup analysis. Patients with low ALI had poorer prognoses. We recommended that surgeons should perform aggressive interventions in patients with low ALI before the operation.

BACKGROUND: Whether hypokalemia can affect the short-term outcomes of CRC patients after radical surgery remains unclear. The purpose of this study was to investigate the impact of preoperative hypokalemia on the short-term outcomes for colorectal cancer (CRC) patients who underwent radical CRC surgery using propensity score matching (PSM). METHODS: We retrospectively enrolled consecutive CRC patients from Jan 2011 to Dec 2021 in a single-center hospital. Hypokalemia was defined as a serum potassium concentration < 3.5 mmol/L. The short-term outcomes were compared between the hypokalemia group and the normal blood potassium group. In addition, univariate and multivariate logistic regression analyses were conducted to identify independent risk factors for overall complications. RESULTS: A total of 6183 CRC patients who underwent radical surgery were included in this study, of whom 390 (6.3%) patients were diagnosed with hypokalemia before surgery. After 1:1 ratio PSM, there were 390 patients in the hypokalemia group and in the normal potassium group. No significant difference was found between the two groups after PSM in terms of baseline information (p > 0.05). Regarding short-term outcomes, the hypokalemia group had a longer hospital stay (p = 0.028), a higher proportion of overall complications (p = 0.048) and a higher incidence of postoperative pneumonia (p = 0.008) after PSM. Moreover, hypokalemia (p = 0.036, OR = 1.291, 95% CI = 1.017-1.639) was an independent risk factor for overall complications. CONCLUSION: Preoperative hypokalemia could increase complications after CRC surgery and prolong the hospital stay. Moreover, preoperative hypokalemia was an independent risk factor for overall complications.

PURPOSE: The purpose of this study is to analyze the effect of body mass index (BMI) on patients with concurrent colorectal cancer (CRC) and type 2 diabetes mellitus (T2DM). METHODS: Patients who underwent primary radical CRC surgery from Jan 2011 to Jan 2020 were retrospectively collected. The perioperative information, overall survival (OS) and disease-free survival (DFS) were compared between the higher BMI group and the lower BMI group. RESULTS: A total of 574 patients with concurrent CRC and T2DM were included in this study. The higher BMI group had higher portion of hypertension (p < 0.01) and coronary heart disease (CHD) (p < 0.01). Furthermore, the higher BMI group had better OS (p = 0.016) and DFS (p = 0.040) than the lower BMI group in stage II CRC. In multivariate analysis, age (OS: p = 0.002, HR = 2.016, 95% CI = 1.307-3.109/ DFS: p = 0.003, HR = 1.847, 95% CI = 1.230-2.772), TNM stage (OS: p < 0.01, HR = 1.667, 95% CI = 1.281-2.169/ DFS: p = 0.001, HR = 1.545, 95% CI = 1.207-1.977), overall complications (OS: p = 0.004, HR = 1.837, 95% CI = 1.218-2.880/ DFS: p = 0.006, HR = 1.783, 95% CI = 1.184-2.686) and major complications (OS: p = 0.005, HR = 2.819, 95% CI = 1.376-5.774/ DFS: p = 0.014, HR = 2.414, 95% CI = 1.196-4.870) were independent factors of OS and DFS. Moreover, BMI (p = 0.019, HR = 0.413, 95% CI = 0.197-0.864) was an independent factor of OS in stage II CRC. CONCLUSION: Higher BMI was associated with better OS in diabetic patients with stage II CRC.

PURPOSE: The purpose of the current study is to analyze the difference of short-term and oncologic outcomes between younger and older colorectal cancer (CRC) patients who underwent primary CRC surgery using a propensity score matching (PSM) analysis. METHODS: We retrospectively collected CRC patients who underwent primary surgery in a single clinical database from Jan 2011 to Jan 2020. The short-term and oncologic outcomes were compared between younger aged group and older aged group. RESULTS: A total of 4599 patients were included in this study, and there were 4196 patients in older aged group and 403 patients in younger aged group. After 1:1 ratio PSM, there were 401 patients in each group. No significant difference was found in terms of baseline information after PSM (p>0.05). Younger aged group had larger retrieved lymph nodes before (p<0.001) and after PSM (p=0.001) than older aged group. In multivariate analysis, younger age was an independent predictor of better overall survival (OS) (p<0.001, HR=2.303, 95% CI=1.658-3.199) and disease-free survival (DFS) (p=0.008, HR=1.425, 95% CI=1.098-1.850). In terms of different tumor stage after PSM, younger aged group had better OS than older group in stage II (p<0.001) and stage IV (p=0.028) CRC, and younger aged group had better DFS than older group in stage II (p=0.016) CRC. CONCLUSION: Younger CRC patients had larger retrieved lymph nodes and better prognosis than older CRC patients after primary CRC surgery.

The purpose of this study was to evaluate the effect of colorectal cancer surgery on hypertension. Patients who underwent colorectal cancer surgery were retrospectively enrolled. Hypertension before and 1 year after colorectal cancer surgery was recorded. As a result, eighty patients had remission of hypertension, 307 patients had no remission 1 year after colorectal cancer surgery, and the remission rate was 20.7%. In conclusion, patients with concurrent colorectal cancer and hypertension had a 20.7% remission rate 1 year after colorectal cancer surgery. Age, but not the type of surgery, was a predictive factor for the remission of hypertension.

PURPOSE: The purpose of this study was to investigate the short-term outcomes and prognosis of elderly and very elderly colorectal cancer (CRC) patients after primary CRC surgery using propensity score matching (PSM). METHODS: This study retrospectively collected the medical records of CRC patients ≥ 65 years old undergoing primary CRC surgery from Jan 2011 to Jan 2020. Short-term outcomes, overall survival (OS) and disease-free survival (DFS) were compared between very elderly CRC patients (≥ 80 years old) and elderly CRC patients (65-79 years old). RESULTS: A total of 2084 patients were enrolled for analysis. After PSM, 331 very elderly patients were matched to 331 elderly patients. In terms of short-term outcomes, the very elderly patients had longer postoperative hospital stays (p = 0.007) after PSM. In terms of OS, it was found that age (p < 0.01, HR = 1.878, 95% CI 1.488-2.371), tumor stage (p < 0.01, HR = 1.865, 95% CI 1.603-2.170), overall complications (p < 0.01, HR = 1.514, 95% CI 1.224-1.872) and major complications (p = 0.001, HR = 2.012, 95% CI 1.319-3.069) were independent prognostic factors. For DFS, age (p < 0.01, HR = 1.816, 95% CI 1.579-2.088), tumor stage (p < 0.01, HR = 1.816, 95% CI 1.579-2.088), overall complications (p = 0.002, HR = 1.379, 95% CI 1.128-1.685) and major complications (p = 0.002, HR = 1.902, 95% CI 1.259-2.874) were found to be independent prognostic factors. Moreover, elderly patients had a better OS and DFS than very elderly patients. CONCLUSION: Very elderly patients had a poorer prognosis than elderly patients after primary CRC surgery. Surgeons should be cautious when treating very elderly CRC patients.

PURPOSE: The purpose of the current study is to identify the predictors of planned and unplanned admission to intensive care units (ICU) after colorectal cancer (CRC) surgery. METHODS: We retrospectively collected CRC patients' information from January 2016 to June 2021 in a single clinical center. The predictors of planned and unplanned admission to ICU after CRC surgery were analyzed. RESULTS: A total of 4263 patients were included in this study and there were 349 (8.2%) CRC patients who were admitted to ICU. There were 34 (9.7%) CRC patients in unplanned ICU admission group and 315 (90.3%) CRC patients in planned ICU admission group. Older age (p < 0.01, OR = 1.093, 95% CI = 1.079-1.108), male (p = 0.013, OR = 0.721, 95% CI = 0.557-0.933), lower body mass index (BMI) (p = 0.001, OR = 0.932, 95% CI = 0.896-0.971), type 2 diabetes mellitus (T2DM) (p = 0.035, OR = 1.422, 95% CI = 1.024-1.975), coronary heart disease (CHD) (p = 0.036, OR = 1.579, 95% CI = 1.031-2.420), colon cancer (p = 0.002, OR = 1.475, 95% CI = 1.149-1.894), advanced tumor stage (p = 0.003, OR = 1.265, 95% CI = 1.082-1.478), longer operation time (p = 0.005, OR = 1.002, 95% CI = 1.001-1.003), and larger blood loss (p < 0.01, OR = 1.002, 95% CI = 1.001-1.002) were independent predictors of planned ICU admission. Older age (p < 0.01, OR = 1.062, 95% CI = 1.029-1.097) and longer operation time (p = 0.003, OR = 1.004, 95% CI = 1.001-1.007) were independent predictors of unplanned ICU admission. CONCLUSION: Cautions should be paid for CRC patients with predictive factors to avoid unnecessary ICU admission.

PURPOSE: We introduced a novel colorectal anastomotic technique, double-angle anastomosis combined with the double stapling technique (DAA-DST), to simplify the anastomosis step during natural orifice specimen extraction surgery (NOSES) and compared its safety and effectiveness with purse string anastomosis combined with the double stapling technique (PSA-DST). METHODS: Between January 2018 and March 2021, 63 patients with colorectal cancer underwent NOSES with DAA-DST or PSA-DST. We compared the perioperative and oncological outcomes between the groups. RESULTS: There were no significant differences in the operation time, blood loss, time to first passage of flatus and excrement or hospital stay duration between PSA-DST and DAA-DST groups. The overall postoperative complication rates were similar (DAA-DST vs PSA-DST, 21.2% vs 26.7%, p = 0.78), including the rate of anastomotic leakage (6.1% vs 10%, p = 0.91). The rate of successful DAA-DST was higher than that of PSA-DST (100% vs 93.3%). The DAA-DST group had a lower rate of positive drain fluid culture than the PSA-DST group (18.2% vs 26.7% p = 0.61). Recurrence (3.01% vs 6.67%, p = 0.93) and metastasis rates (6.06% vs 6.67%, p = 0.98) were similar between the groups. CONCLUSION: DAA-DST is a safe and effective procedure and can simplify the procedure of NOSES.

PURPOSE: The purpose of the current study was to compare the outcomes of temporary stoma through the specimen extraction site (SSES) and stoma through a new site (SNS) after laparoscopic low anterior resection. METHODS: The rectal cancer patients who underwent laparoscopic low anterior resection plus temporary ileostomy were recruited in a single clinical database from Jun 2013 to Jun 2020. The SSES group and the SNS group were compared using propensity score matching (PSM) analysis. RESULTS: A total of 257 rectal cancer patients were included in this study, there were 162 patients in the SSES group and 95 patients in the SNS group. After 1:1 ratio PSM, there was no difference in baseline information (p > 0.05). The SSES group had smaller intraoperative blood loss (p = 0.016 < 0.05), shorter operation time (p < 0.01) and shorter post-operative hospital stay (p = 0.021 < 0.05) than the SNS group before PSM. However, the SSES group shorter operation time (p = 0.006 < 0.05) than the SNS group after PSM, moreover, there was no significant difference in stoma-related complications (p > 0.05). In the multivariate analysis, longer operation time was an independent factor (p = 0.019 < 0.05, OR = 1.006, 95% CI = 1.001-1.011) for the stoma-related complications. CONCLUSION: Based on the current evidence, the SSES group had smaller intraoperative blood loss, shorter operation time and shorter post-operative hospital stay before PSM, and shorter operation time after PSM. Therefore, SSES might be superior than SNS after laparoscopic low anterior resection for rectal cancer patients.

PURPOSE: The purpose of this meta-analysis was to evaluate the effect of liver cirrhosis (LC) on the short-term and long-term surgical outcomes of colorectal cancer (CRC). METHODS: The PubMed, Embase, and Cochrane Library databases were searched from inception to March 23, 2021. The Newcastle-Ottawa Scale (NOS) was used to assess the quality of enrolled studies, and RevMan 5.3 was used for data analysis in this meta-analysis. The registration ID of this current meta-analysis on PROSPERO is CRD42021238042. RESULTS: In total, five studies with 2485 patients were included in this meta-analysis. For the baseline information, no significant differences in age, sex, tumor location, or tumor T staging were noted. Regarding short-term outcomes, the cirrhotic group had more major complications (OR=5.15, 95% CI=1.62 to 16.37, p=0.005), a higher re-operation rate (OR=2.04, 95% CI=1.07 to 3.88, p=0.03), and a higher short-term mortality rate (OR=2.85, 95% CI=1.93 to 4.20, p<0.00001) than the non-cirrhotic group. However, no significant differences in minor complications (OR=1.54, 95% CI=0.78 to 3.02, p=0.21) or the rate of intensive care unit (ICU) admission (OR=0.76, 95% CI=0.10 to 5.99, p=0.80) were noted between the two groups. Moreover, the non-cirrhotic group exhibited a longer survival time than the cirrhotic group (HR=2.96, 95% CI=2.28 to 3.85, p<0.00001). CONCLUSION: Preexisting LC was associated with an increased postoperative major complication rate, a higher rate of re-operation, a higher short-term mortality rate, and poor overall survival following CRC surgery.

Background: Colorectal cancer (CRC) is one of the most common cancers worldwide. In the treatment of patients with CRC, oxaliplatin plays a pivotal role, with moderate side effects. Neurotoxicity, myelosuppression, ototoxicity, delayed hypersensitivity reactions, and rhabdomyolysis induced by oxaliplatin have been reported individually. However, the occurrence of oxaliplatin-induced ascites has not been reported previously. The objectives of this case report were to elaborate on the rare occurrence of ascites in a patient with CRC after oxaliplatin therapy and to explore its characteristics and causes. Case description: We report on a case of upper rectal cancer seen in a 65-year-old man who underwent robotic-assisted laparoscopic anterior rectal resection. The patient developed ascites during postoperative adjuvant therapy with oxaliplatin and capecitabine. We ruled out tumor recurrence by laparoscopy, intraoperative biopsy, and biochemistry of the ascites. The patient did not experience a recurrence of ascites after discontinuation of chemotherapy. Conclusion: This case suggests that chemotherapy with oxaliplatin might cause ascites. The mechanism of the oxaliplatin-induced liver injury was further discussed, which might have been the cause of ascite formation. When patients with CRC who underwent chemotherapy with oxaliplatin develop ascites, surgeons should actively determine whether this is a side effect of chemotherapy or is due to tumor recurrence in order to avoid unnecessary surgery.
RESUMEN
BACKGROUND: Robotic surgery (RS) is gaining popularity; however, evidence for abdominoperineal resection (APR) of rectal cancer (RC) is scarce. AIM: To compare the efficacy of RS and laparoscopic surgery (LS) in APR for RC. METHODS: We retrospectively identified patients with RC who underwent APR by RS or LS from April 2016 to June 2022. Data regarding short-term surgical outcomes were compared between the two groups. To reduce the effect of potential confounding factors, propensity score matching was used, with a 1:1 ratio between the RS and LS groups. A meta-analysis of seven trials was performed to compare the efficacy of robotic and laparoscopic APR for RC surgery. RESULTS: Of 133 patients, after propensity score matching, there were 42 patients in each group. The postoperative complication rate was significantly lower in the RS group (17/42, 40.5%) than in the LS group (27/42, 64.3%) (P = 0.029). There was no significant difference in operative time (P = 0.564), intraoperative transfusion (P = 0.314), reoperation rate (P = 0.314), lymph nodes harvested (P = 0.309), or circumferential resection margin (CRM) positive rate (P = 0.314) between the two groups. The meta-analysis showed patients in the RS group had fewer positive CRMs (P = 0.04), lesser estimated blood loss (P < 0.00001), shorter postoperative hospital stays (P = 0.02), and fewer postoperative complications (P = 0.002) than patients in the LS group. CONCLUSION: Our study shows that RS is a safe and effective approach for APR in RC and offers better short-term outcomes than LS.
RESUMEN
BACKGROUND: The CRC-VTE trial conducted in China revealed a significant occurrence of venous thromboembolism (VTE) in patients following colorectal cancer (CRC) surgery, raising concerns about implementing thromboprophylaxis measures. The present study aimed to identify and analyze inappropriate aspects of current thromboprophylaxis practices. METHODS: This study performed an analysis of the CRC-VTE trial, a prospective multicenter study that enrolled 1836 patients who underwent CRC surgery. The primary objective was to identify independent risk factors for VTE after CRC surgery using multivariate logistic regression analysis. Furthermore, among the cases in which VTE occurred, the appropriateness of thromboprophylaxis was assessed based on several factors, including pharmacologic prophylaxis, time to initiate prophylaxis, drug selection, drug dosage, and duration of pharmacologic prophylaxis. Based on the analysis of the current state of thromboprophylaxis and relevant clinical guidelines, a modified Delphi method was used to develop a clinical pathway for VTE prophylaxis after CRC surgery. RESULTS: In this analysis of 1836 patients, 205 (11.2%) were diagnosed with VTE during follow-up. The multifactorial analysis identified several independent risk factors for VTE, including age (≥70 years), female sex, varicose veins in the lower extremities, intraoperative blood transfusion, and the duration of immobilization exceeding 24 h. None of the patients diagnosed with VTE in the CRC trial received adequate thromboprophylaxis. The main reasons for this inappropriate practice were the omission of thromboprophylaxis, delayed initiation, and insufficient duration of thromboprophylaxis. We developed a specialized clinical pathway for thromboprophylaxis after CRC surgery to address these issues. CONCLUSIONS: This study offers a comprehensive nationwide evaluation of existing thromboprophylaxis practices in patients after CRC surgery in China. A specialized clinical pathway was developed to address the identified gaps and improve the quality of care. This clinical pathway incorporates explicit, tailored, detailed recommendations for thromboprophylaxis after CRC surgery.

PURPOSE: This study aims to introduce a new anastomotic technique-transanal pull-through combined with single stapling technique (PT-SST), and evaluate the value in the sphincter-preserving operation for lower rectal carcinoma. METHODS: Between January 2004 and September 2011, 131 consecutive patients had sphincter-preserving operations using PT-SST and double stapling technique (DST) for low colorectal anastomosis. The data was prospectively collected. RESULTS: There are 45 patients (male 26, median = 55 years) in PT-SST group and 86 (male 46, median = 55 years) in the DST group. Anastomotic leakage took place in three patients in DST group, while no anastomotic leakage happened in PT-SST group. There are recurrences in pelvic cavity for one patient (2.2 %), in anastomotic stoma for no patient, and hepatic metastasis for four patients (8.9 %) in PT-SST group; while there are recurrences in pelvic cavity for three patients (3.5 %), in anastomotic stoma for two patients (2.3 %), and hepatic metastasis for seven patients (8.1 %) in DST group. No significant difference was indicated in the terms of the recurrence and hepatic metastasis between the two groups. Patients were satisfied with functional results. CONCLUSIONS: This new technique can solve some technique problems of DST and has at least comparable outcomes compared with DST. It is a safe and feasible procedure for performing low anastomosis with high rate of sphincter preservation. It can be used especially for patients with small pelvis.

Introduction: The clinical utility of glutamine in patients undergoing colorectal cancer (CRC) surgery remains unclear. Therefore, we aimed to investigate the impact of postoperative treatment with glutamine on postoperative outcomes in patients undergoing CRC surgery. Methods: We included patients with CRC undergoing elective surgery between January 2014 and January 2021. Patients were divided into the glutamine and control groups. We retrospectively analyzed postoperative infections complications within 30 days and other outcomes using propensity score matching and performed between-group comparisons. Results: We included 1,004 patients who underwent CRC surgeries; among them, 660 received parenteral glutamine supplementation. After matching, there were 342 patients in each group. The overall incidence of postoperative complications was 14.9 and 36.8% in the glutamine and control groups, respectively, indicating that glutamine significantly reduced the incidence of postoperative complications [p < 0.001; risk ratio (RR) 0.41 [95% CI 0.30-0.54]]. Compared with the control group, the glutamine group had a significantly lower postoperative infection complications rate (10.5 vs. 28.9%; p < 0.001; RR 0.36 [95% CI 0.26-0.52]). Although there was no significant between-group difference in the time to first fluid diet (p = 0.052), the time to first defecation (p < 0.001), first exhaust (p < 0.001), and first solid diet (p < 0.001), as well as hospital stay (p < 0.001) were significantly shorter in the glutamine group than in the control group. Furthermore, glutamine supplementation significantly reduced the incidence of postoperative intestinal obstruction (p = 0.046). Moreover, glutamine supplementation alleviated the decrease in albumin (p < 0.001), total protein (p < 0.001), and prealbumin levels (p < 0.001). Conclusions: Taken together, postoperative parenteral glutamine supplementation can effectively reduce the incidence of postoperative complications, promote the recovery of intestinal function, and improve albumin levels in patients undergoing CRC surgery.
