“…According to the results in Figure , we suggested that the CUSUM of OT decreased gradually after 33 cases as the surgeon's experience expanded. However, OT alone can‐not accurately assess the LC because in addition to an adequate surgical technique competent, there are many other factors that indicate the surgical quality, such as short‐term morbidity, mortality, conversion and oncologic outcomes . Additionally, factors that reflect the pathologic outcomes, such as tumor diameter, harvested number of lymph nodes, proximal and distal margins, and local recurrence, should be considered for cancer surgery.…”

“…Additionally, factors that reflect the pathologic outcomes, such as tumor diameter, harvested number of lymph nodes, proximal and distal margins, and local recurrence, should be considered for cancer surgery. Previous studies used some parameters to define surgical failure, such as, conversion to open procedure, microscopic margins, postsurgical morbidity within 30 days, harvested lymph node count <12, and local recurrence. We combined the characteristics of sigmoid colon and upper rectal cancer and used RA‐CUSUM with four parameters of conversion, postoperative complication of grade III, lymph nodes less than 12 and local recurrence to define surgical failure to assess the LC more accurately.…”

Laparoscopic-assisted rectal resection (LAR) has been widely used to treat rectal cancer. However, it has a steep learning curve. In this study, we aimed to investigate the effects of the learning curve on the outcomes of LAR. All consecutive patients with rectal cancer undergoing LAR or open resection (OR) between 2010 and 2015 were included in this retrospective analysis. The learning curve was determined, and patients were divided into 2 phases: the learning curve and the expert period. The short-term perioperative data in the 2 phases and the long-term survival in the learning phase were compared between the LAR and OR groups. A total of 491 patients were included in this study. Inflection of the learning curve based on the operation time of LAR was at the 40th case. A total of 233 patients underwent surgery (112 LAR and 121 OR) during the learning period. In this period, LAR had a longer operation time, less blood loss, and a higher total cost (all P < .05). The 3-year overall survival rates between the LAR and OR groups were similar (69.74% vs 75%; P = .32). A total of 258 patients underwent surgery (169 LAR and 89 OR) during the expert period. Significant differences in total cost, estimated blood loss, postoperative hospital stay, and recovery of bladder and bowel functions were identified in this period (all P < .05). LAR during the learning period has fewer benefits in terms of postoperative recovery than OR. However, the long-term outcomes are equivalent.

“…and has since gained great popularity among colorectal surgeons [75]. The learning curve for SILS colectomy spans between 30 and 60 cases, according to various reports [76, 77]. As surgeons have accumulated more experience with the SILS platform, operating times have shortened and became comparable with CML [78].…”

Throughout history, surgeons have been on a quest to refine the surgical treatment options for their patients and to minimize operative trauma. During the last three decades, there have been tremendous advances in the field of minimally invasive colorectal surgery, with an explosion of different technologies and approaches offered to treat well-known diseases. Laparoscopic surgery has been shown to be equal or superior to open surgery. The boundaries of laparoscopy have been pushed further, in the form of single-incision laparoscopy, natural-orifice transluminal endoscopic surgery and robotics. This paper critically reviews the pathway of development of minimally invasive surgery, and appraises the different minimally invasive colorectal surgical approaches available to date.
