Purpose: Low anterior resection syndrome (LARS) has had many impacts on the lives of patients and substantial differences in emotional and social functions. The aim of this study was to investigate the correlation analysis of different personality traits in rectal cancer patients with LARS after undergoing curative surgery. Methods: This study was designed as a prospective cohort study. The inclusion criteria included (1) participants diagnosed with rectal cancer who underwent surgical resection of malignant tumors and (2) ECOG 0–1. The primary outcome was the correlation between different personality traits and low anterior resection syndrome in rectal cancer patients after radical surgery. Low anterior resection syndrome incidence rates were estimated by questionnaires and personality groups by the Type A and Type D Scale‐14 Personality Inventory. Results: For all 161 participants in this study, the presence of a tumor at the lower anal verge and the receipt of neoadjuvant CCRT had a statistically significant positive correlation with the LARS score at 1 month, 6 months, and 1 year (Pearson correlation coefficient = −0.283, −0.374, and − 0.205, respectively), with a p value of less than 0.05. Personalities with Type A, Type D, and Type D‐SI scores had a statistically significant positive correlation with LARS score at 1 month (Pearson correlation coefficient = 0.172, 0.162, and 0,164, p value = 0.03, 0.04, and 0.04). Conclusion: Type A and Type D personalities are highly linked to LARS. Personalized support approaches can ultimately assist rectal cancer patients in overcoming difficulties after surgery and recovery and enhance their functional outcomes. [ABSTRACT FROM AUTHOR]

Background: Although a temporary stoma can mitigate the severity of anastomotic leakage, some rectal cancer patients retain a permanent stoma after sphincter-preserving surgery. Therefore, this study aimed to identify independent preoperative risk factors for permanent stoma and establish a prediction model for mid-and low-rectal cancer patients who underwent sphincter-preserving surgery and temporary stoma. Methods: We retrospectively reviewed consecutive patients with non-metastatic rectal cancer between 2000 and 2015. The risk factors for permanent stomas were collected and analyzed. Results: A total of 1020 rectal cancer patients with temporary stoma were included. The overall rate of permanent stoma was 17.5% (n = 179). Cancer progression and anastomotic complications are major causes of permanent stomas. Multivariate analysis showed that preoperative risk factors such as advanced age, male sex, preoperative CEA ≥ 10 ng/ml, T4 stage, N stage, low rectal tumor, and ASA ≥ III were independent preoperative risk factors after adjustment. The ROC curve of the risk factors and permanent stoma showed an AUC of 0.689, a cut-off value of 2.5, a sensitivity of 0.689, and a specificity of 0.622. The permanent stoma rates were significantly higher between risk scores ≤ 2 and > 2 (29.9% vs. 11.3%, p < 0.001). Conclusion: Preoperative CEA ≥ 10 ng/ml, T4 stage, N stage, low rectal tumor, advanced age, ASA ≥ III, and male sex were independent preoperative prognostic factors for a permanent stoma. The risk was higher with a score greater than two. Therefore, the risk of subsequent permanent stoma should be evaluated and informed to the patient prior to the primary surgery.

Purpose: Although cigarette smoking is a well-known risk factor for anastomotic leakage during rectal surgery, the proper duration of smoking cessation that can decrease anastomotic leakage in patients undergoing sphincter-preserving surgery is unclear. This study aimed to investigate the optimal duration of smoking cessation that can reduce this complication. Methods: Between January 1, 2000, and December 31, 2012, we enrolled 1246 consecutive patients who underwent curative-intent sphincter-preserving surgery without preventive stoma at the Division of Colorectal Surgery of a tertiary referral center in Taiwan. Questionnaires were used to record their pre-surgical smoking status. The receiver operating characteristic (ROC) curve was used to determine the optimal cut-off duration of smoking cessation. Multivariate analysis was used to verify the effect of cigarette cessation on anastomotic leakage. Results: The ROC curve showed a cut-off value of 10.5 years of cessation duration. Therefore, the former-smoker group was further divided using a cessation duration of 10 years. The overall anastomotic leakage rate was 5.29%. However, the anastomotic leakage rate in current smokers (9.3%) and in those who quit for < 10 years (12.9%) was significantly higher than that in non-smokers (3.3%) and those who quit for ≥ 10 years (4.5%). On multivariate analysis, current smokers (p = 0.022), former smokers with < 10 years of smoking cessation (OR 2.725; p = 0.029), male sex (p = 0.015), and low rectal cancer (p < 0.001) were all independently related to the development of anastomotic leakage. Conclusion: Smoking cessation for < 10 years remains a risk factor for anastomotic leakage in patients with mid-to-low rectal cancer undergoing sphincter-preserving surgery. [ABSTRACT FROM AUTHOR]

Aim: Laparoscopic anterior resection with natural orifice specimen extraction (NOSE) has favourable short-term outcomes. However, NOSE is rarely adopted for left hemicolectomy procedures. This study aimed to review the feasibility, safety and short-term outcomes of transrectal NOSE in patients undergoing laparoscopic left hemicolectomy. Method: All consecutive patients who underwent laparoscopic left hemicolectomy surgery with transrectal NOSE in a single institution between January 2018 and December 2020 were reviewed. Transrectal NOSE was performed with an enterotomy at the upper rectum. The specimen was brought out via a transanal endoscopic microsurgery scope inserted through the anus. A supplementary video demonstrates this technique. Surgical outcomes, including complications, postoperative short-term recovery and the level of pain intensity, are presented. Results: Twenty patients were reviewed. There were no immediate postoperative complications and no wound infections in these patients. The average time to tolerate a soft diet was 3.6 days, and the average postoperative hospital stay was 4.5 days. The average score on the numerical rating scale of postoperative pain was 3.0 on postoperative day 1. The median follow-up time was 23.5 months. Conclusion: Laparoscopic left hemicolectomy with transrectal NOSE is a safe and feasible procedure that leads to early postoperative recovery and a short hospital stay. [ABSTRACT FROM AUTHOR]

Background: Laparoscopic surgery has achieved significant results in elderly patients with colorectal cancer (CRC). In this study, we compared the short-term and long-term outcomes of open surgery and laparoscopic surgery in patients with CRC aged above 75 years at a single tertiary medical center.Methods: We analyzed 967 patients who underwent curative resection for primary colorectal adenocarcinoma without distant metastasis between January 2009 and December 2015, in a single institution. Of the enrolled patients, 305 underwent laparoscopic surgery, and 662 received open laparotomy surgery.Results: Compared to the patients who underwent open surgery, those who received laparoscopic surgery had significantly shorter postoperative stay (10.3 vs. 13.5 days p < 0.001) and similar postoperative morbidity (p = 0.354) and mortality (p = 0.082). In the laparoscopy cohort, six of 305 patients were converted to open surgery and one died. The long-term overall survival, cancer-specific survival, and recurrence rate were similar between both cohorts in each stage.Conclusions: Laparoscopic surgery is suitable for elderly patients owing to shorter postoperative stay, similar long-term outcomes with open surgery, and acceptable low conversion rates. For long-term overall and oncological outcomes, the results of laparoscopic surgery were similar to that of open surgery in each TNM stage. [ABSTRACT FROM AUTHOR]

Background: Local excision (LE) is a feasible treatment approach for rectal cancers in stage pT1 and presents low pathological risk, whereas total mesorectal excision (TME) is a reasonable treatment for more advanced cancers. On the basis of the pathology findings, surgeons may suggest TME for patients receiving LE. This study compared the survival outcomes between LE with/without chemoradiation and TME in mid and low rectal cancer patients in stage pT1/pT2, with highly selective intermediate pathological risk. Methods: This retrospective study included 134 patients who received TME and 39 patients who underwent LE for the treatment of intermediate risk (pT1 with poor differentiation, lymphovascular invasion, perineural invasion, relatively large tumor, or small-sized pT2 tumor) rectal cancer between 1998 and 2016. Results: Overall survival (OS), disease-free survival (DFS), and cumulative recurrence rate (CRR) were similar between the LE (3-year DFS 92%) and TME (3-year DFS 91%) groups. Following subgrouping into an LE with adjuvant therapy group and a TME without adjuvant therapy group, the compared survival outcomes (OS, DFS, and CRR) were found not to be statistically different. The temporary and permanent ostomy rates were higher in the TME group than in the LE group (p < 0.001). Rates of early and late morbidity following surgery were higher in the TME group (p = 0.005), and LE had similar survival compared with TME. Conclusion: For patients who had mid and low rectal cancer in stage pT1/pT2 and intermediate pathological risk, LE with chemoradiation presents an alternative treatment option for selected patients.
