Background No previous study has compared the risk of surgical site infection (SSI) between intracorporeal anastomosis (IA) and extracorporeal anastomosis (EA) related to intra-abdominal infection in laparoscopic right hemicolectomy. Therefore, this study aimed to compare the risk of SSI in IA and EA in this context. Methods From July 2014 to March 2018, 101 consecutive (median age, 73 years; male, 54) patients underwent laparoscopic right hemicolectomy for colon cancer. The IA and EA groups consisted of 51 and 50 cases, respectively. After either IA or EA, lavage was performed with 100 mL of saline in the area surrounding the anastomosis, and a sample was collected for bacterial culture. The product of the virulence score and dose of bacterial contamination score called the risk of SSI score was evaluated in both groups, and short-term outcomes in both groups were analyzed retrospectively. Results No significant difference was found in patient characteristics between the 2 groups. The frequency of organ/space SSI in the IA group was significantly higher than that in the EA group (7.8% vs 0%, P = .04). The risk of SSI score was significantly higher in the IA group than in the EA group (median, 9 vs 1, P < .01). Conclusions Compared with EA, IA in laparoscopic right hemicolectomy increased organ/space SSI rates, signifying intra-abdominal infection. We strongly recommend prevention of intra-abdominal infection when performing an IA.

27 Background: A standard anastomotic configuration after right hemicolectomy is not well established, although short-term benefits of end-to-side anastomosis have been reported. This study was designed to assess the superiority of end-to-side anastomosis compared to side-to-side anastomosis after laparoscopic right hemicolectomy for colon cancer under an enhanced recovery program. Methods: Between September 2016 and August 2019, 130 patients (18–80 years) scheduled for laparoscopic right hemicolectomy were randomly assigned (1:1) to undergo end-to-side ( n = 65) or side-to-side ( n = 65) anastomosis. All patients underwent an enhanced recovery program with early diet and mobilization. The primary outcome was the cumulative recovery rate 7 days after surgery, defined as the percentage of patients who met all of the following recovery criteria: tolerated diet for 24h, analgesic-free, safe ambulation, and afebrile status without major complications. Results: The cumulative recovery rate did not differ between end-to-side (92.3%, 60/65) and side-to-side anastomosis (92.3%, 60/65) ( P = 1.000). Both approaches had similar cumulative recovery rates at 4, 5, and 6 days (end-to-side vs. side-to-side: 41.5% vs. 35.4%, P = 0.589; 73.8% vs. 63.1%, P = 0.257; 86.2% vs. 81.5%, P = 0.634; respectively) The median recovery time [interquartile range (IQR)] in the end-to-side and side-to-side groups was 105 [90-124] hours and 113 [84-139] hours, respectively ( P = 0.474), showing no significant difference. Length of stay [IQR] was similar in the end-to-side and side-to-side groups (5 [5–7] vs. 6 [5–7] days; P = 0.376). The 30-day complication rate (16.9% vs. 12.3%, P = 0.620), enhanced recovery program failure rate (10.8% vs. 7.7%, P = 0.763), and 30-day readmission rate (4.6% vs. 3.1%; P = 1.000) were not significantly different between the groups. Conclusions: This is the first randomized controlled trial showing that end-to-side anastomosis is not superior to side-to-side anastomosis in terms of short-term outcomes after laparoscopic right hemicolectomy. Clinical trial information: NCT02897531.

Abstract Background and objective Intra-corporeal delta-shaped anastomosis (IDA) is an important development in laparoscopic digestive-tract reconstruction. We applied it in laparoscopic right hemicolectomy for right colon cancer and compared the short-term outcomes between the patients treated with IDA and conventional extracorporeal anastomosis (EA). Methods Between 1 January 2016 and 1 October 2017, 36 and 50 patients who underwent IDA and EA, respectively, were included. Data on clinicopathological characteristics, surgical outcomes, post-operative recovery and complications were collected and compared between the two groups. Results Surgical outcomes and clinicopathological characteristics were similar between the two groups except the length of incision, which was significantly shorter in the IDA group than in the EA group (4.6 ± 0.6 vs 5.6 ± 0.7 cm, P < 0.001). The time to ground activities, fluid diet intake and post-operative hospitalization did not differ between the groups; however, the time to first flatus was significantly shorter in the IDA group than in the EA group (2.8 ± 0.5 vs 3.2 ± 0.8 days, P = 0.004). The post-operative visual analogue scale for pain was lower in the IDA group than in the EA group on post-operative Day 1 (4.0 ± 0.7 vs 4.5 ± 1.0, P = 0.002) and post-operative Day 3 (2.7 ± 0.6 vs 3.4 ± 0.6, P < 0.001). The surgical complication rates were 8.3 and 16.0% in the IDA and EA groups (P = 0.470), respectively. No complications such as anastomotic bleeding, stenosis and leakage occurred in any patient. Conclusions IDA is safe and feasible and shows more satisfactory short-term outcomes than EA.

Memory Register

Visual tracking is a challenging computer vision task due to the significant observation changes of the target. By contrast, the tracking task is relatively easy for humans. In this article, we propose a tracker inspired by the cognitive psychological memory mechanism, which decomposes the tracking task into sensory memory register, short-term memory tracker, and long-term memory tracker like humans. The sensory memory register captures information with three-dimensional perception; the short-term memory tracker builds the highly plastic observation model via memory rehearsal; the long-term memory tracker builds the highly stable observation model via memory encoding and retrieval. With the cooperative models, the tracker can easily handle various tracking scenarios. In addition, an appearance-shape learning method is proposed to update the two-dimensional appearance model and three-dimensional shape model appropriately. Extensive experimental results on a large-scale benchmark data set demonstrate that the proposed method outperforms the state-of-the-art two-dimensional and three-dimensional trackers in terms of efficiency, accuracy, and robustness.
