["Watch and wait" strategy after neoadjuvant therapy for rectal cancer: status survey of perceptions, attitudes and treatment selection in Chinese surgeons].
Objective: To understand the perceptions, attitudes and treatment selection of Chinese surgeons on the "watch and wait" strategy for rectal cancer patients after achieving a clinical complete response (cCR) following neoadjuvant chemoradiotherapy (nCRT). Methods: A cross-sectional survey was used in this study. Selection of subjects: (1) Domestic public grade III A (provincial and prefecture-level) oncology hospitals or general hospitals possessing the radiotherapy department and the diagnosis and treatment qualifications for colorectal cancer. (2) Surgeons of deputy chief physician or above. ⋯ Conclusions: Chinese surgeons seem to have inadequate knowledge of non-operative management for rectal cancer patients achieving cCR after nCRT and show relatively conservative attitudes toward the strategy. Chinese consensus needs to be formed to guide the non-operative management in selected patients. Chinese Watch & Wait Database (CWWD) is also needed to establish and provide more evidence for the use of alternative procedure after a cCR following nCRT.

[Analysis on prognosis and influencing factors of postoperative low anterior resection syndrome for rectal cancer patients undergoing laparoscopic anus-preserving radical resection].
Objective: To investigate the prognosis and influencing factors of postoperative low anterior resection syndrome (LARS) for rectal cancer patients undergoing laparoscopic sphincter-preserving radical resection. Methods: A retrospective case-control study was used in this study. Clinical data of 268 rectal cancer patients undergoing laparoscopic sphincter-preserving radical resection at Department of Gastrointestinal Surgery of The First Affiliated Hospital of Bengbu Medical College from January 2016 to January 2018 were retrospectively collected. ⋯ Conclusions: The incidence of LARS after laparoscopic sphincter-preserving radical resection decreases with time. The improvement rate within postoperative 1-year of severe LARS is lower than that of mild LARS. Low anastomotic position may lead to impaired improvement of LARS.

[Effect of preservation of left colic artery on postoperative anastomotic leakage of patients with rectal cancer after neoadjuvant therapy].
Objective: To evaluate the effect of preservation of left colic artery (LCA) on postoperative anastomotic leakage in patients with rectal cancer after neoadjuvant therapy. Methods: A retrospective cohort study was conducted to collect data of rectal cancer patients at Department of Gastrointestinal Surgery of Fujian Cancer Hospital from September 2014 to August 2017. Inclusion criteria: (1) age of 18 to 79 years; (2) rectal adenocarcinoma confirmed by postoperative pathology; (3) patients without preoperative serious cardiovascular and cerebrovascular disease receiving preoperative neoadjuvant radiotherapy or chemoradiotherapy; (4) laparoscopic-assisted anterior rectal resection and distal ileostomy were performed simultaneously; (5) complete clinical data. ⋯ Median follow-up time was 31 months (16 to 51 months), and no long-term complication was found. Local recurrence and distant metastasis were found in 1 case (1.8%) and 7 case (12.5%) in the retained LCA group, while those were found in 2 cases (2.9%) and 5 cases (7.2%) respectively, in the non-retained LCA group, whose differences were not statistically significant (P=1.000, P=0.321 respectively). Conclusion: Preservation of left colic artery not only can ensure radical lymph node dissection efficacy under the condition of similar operation time and blood loss, but also can effectively reduce the incidence of postoperative anastomotic leakage for rectal cancer patients after neoadjuvant therapy.
