Learning curve of laparoscopic low anterior resection in terms of local recurrence

Abstract

Local recurrence rates decreased with increasing surgeon experience, as did other short-term outcomes, especially in advanced disease cases.

Nomogram Prediction of Anastomotic Leakage and Determination of an Effective Surgical Strategy for Reducing Anastomotic Leakage after Laparoscopic Rectal Cancer Surgery

“…In addition, these factors might be associated with the surgeon's laparoscopic experience. The cut-off points of the learning curve for laparoscopic rectal cancer surgery have been shown to be based on the mean operative time (range, 50–90 cases) [25, 32, 33]. In our previous study, we demonstrated that the mean operative time was 240 min after performing 90 cases [25].…”

“…The cut-off points of the learning curve for laparoscopic rectal cancer surgery have been shown to be based on the mean operative time (range, 50–90 cases) [25, 32, 33]. In our previous study, we demonstrated that the mean operative time was 240 min after performing 90 cases [25]. Some investigators have insisted that operative time alone is insufficient as a surrogate marker for laparoscopic surgery [34].…”

“…This study was reviewed and approved by the institutional review board of our hospital. The surgical technique of laparoscopic surgery for rectal cancer has been described previously [25]. Briefly, all patients first underwent mechanical bowel preparation.…”

“…We used RA-CUSUM analysis on the basis of individual risk derived from the logistic regression model. The statistical principles were adapted from the tutorial by Steiner et al [27] and our previous study [25]. CUSUM is calculated as follows: Sn = ( X i − p0 i ), where X i = 0 for success (absence of AL) and 1 for failure (presence of AL), and p0 i denotes the predicted probability of failure for operation i.…”

Pathologic stage following preoperative chemoradiotherapy underestimates the risk of developing distant metastasis in rectal cancer: A comparison to staging without preoperative chemoradiotherapy

“…All patients underwent radical proctectomy, including high ligation of the inferior mesenteric artery, total mesorectal excision, and en bloc resection of the adjacent involved organs . The interval between preoperative CRT and surgery was 6–8 weeks.…”
