Male sex, low anastomosis, preoperative chemoradiation, advanced tumor stage, perioperative bleeding, and multiple firings of the linear stapler increased the risk of AL after laparoscopic surgery for rectal cancer. A diverting stoma might be mandatory in patients with 2 or more of the risk factors identified in this analysis.

In this paper, a novel three-pole coupled-line bandpass filter with a microstrip configuration is presented. Presented bandpass filters use defected ground structure (DGS) sections to simultaneously realize a resonator and an inverter. The proposed coupled-line bandpass filter provides compact size with low insertion-loss characteristic. Furthermore, a DGS shape for a microstrip line is newly proposed. The proposed DGS unit structure has a resonance characteristic in some frequency band. The pro

Preoperative MRI was moderately accurate for the prediction of mesorectal lymph node metastasis. Moreover, preoperative MRI was insufficient for detecting small lymph nodes (<3 mm) with metastasis.

In patients with middle or low rectal cancer, robotic-assisted surgery did not significantly improve the TME quality compared with conventional laparoscopic surgery (ClinicalTrial.gov ID: NCT01042743).

Laparoscopic ISR can be performed safely and offers a minimally invasive sphincter-sparing alternative. The oncological adequacy of laparoscopic ISR requires long-term follow-up data, but the intermediate-term outcomes seem equivalent to those achieved with OS.

In this paper, a novel equivalent circuit and modeling method for a defected ground structure is proposed to design an optimized DGS lowpass filter circuit. The equivalent circuit presented in this paper has parallel capacitance to explain the fringing fields due to the defects on the metallic ground plane. Several comparisons between the EM-simulations on the DGS circuits and circuit simulations on its equivalent circuits are demonstrated to show the validity of the proposed model. Optimization

In selected cases, totally laparoscopic colectomy with transvaginal anastomosis and extraction of specimen is feasible and reproducible and may be an alternative technique for treatment of women with right colon cancer. This approach may provide both an attractive way to increase patient comfort and a bridge to "pure" natural orifice colon surgery.

In our experience, NOSE for mid- and upper rectal cancer had acceptable long-term oncologic outcomes comparable to those of conventional minimal invasive surgery and seems to be a safe alternative to reduce access trauma.

On-device machine learning is critical for mobile products as it enables real-time applications (e.g. AI-powered camera applications), which need to be responsive, always available (i.e. do not require network connectivity) and privacy preserving. The platforms used in such situations have limited computing resources, power, and memory bandwidth. Enabling such on-device machine learning has triggered wide development of efficient neural-network accelerators that promise high energy and area effi
