[Laparoscopic treatment for incidental gallbladder cancer: a retrospective 10 years study from a single institution].
Objective: To explore the feasibility of laparoscopic treatment for incidental gallbladder cancer(IGBCA) and analyze the factors influencing prognosis. Methods: A retrospective study of 71 patients with IGBCA received laparoscopic treatment at Department of General Surgery, Peking University Third Hospital from January 2007 to December 2016 was conducted,the clinicopathological data and prognosis were analyzed. There were 18 males and 53 females,aged 23 to 81 years. ⋯ Univariate analysis demonstrated that T stage, lymph node metastasis, G grade, lymphovascular invasion, neural invasion, acute cholecystectomy, bile spillage, gallbladder mass and preoperative CA19-9/CEA were the most important prognostic factors(P<0.05). Conclusions: Laparoscopic treatment for IGBCA is feasible, especially for those with intraluminal gallbladder mass. The accuracy of frozen section examination in evaluating T stage is low.

Comparative Study[Comparison of three different posterior cervical approaches for treating cervical spine trauma with ossification of posterior longitudinal ligament].
Objective: To investigate the clinical application value of using laminoplasty combine with short-segment pedicle screw fixation in the treatment of cervical spine trauma patients with ossification of posterior longitudinal ligament (OPLL). Methods: Fifty-four cervical spine trauma patients with OPLL from June 2014 to June 2016 were retrospectively analyzed of Department of Spine Surgery, Changzheng Hospital, Naval Military Medical University. There were 31 males and 23 females, aging (68.4±4.3) years (rang: 46 to 82 years). ⋯ The overall mobility of cervical vertebrae in group B was significantly lower than that before surgery (P=0.013). Conclusions: For cervical spine trauma patients with OPLL, laminoplasty combined short-segment pedicle screw fixation can increase cervical segmental stability while extensive decompression of cervical spinal cord compression. At the same time, to some extent, the complications of postoperative axial symptoms caused by posterior cervical laminectomy and pedicle screw fixation were avoided.

Comparative Study[Robotic versus laparoscopic distal pancreatectomy: a retrospective single-center study].
Objective: To compare the short-term clinical outcomes and cost differences of robotic distal pancreatectomy (RDP) versus laparoscopic distal pancreatectomy (LDP). Methods: The retrospective descriptive study was adopted. The clinical data of 158 patients underwent minimally invasive distal pancreatectomy who were admitted to Fujian Medical University Union Hospital between January 2016 and July 2018 were collected. ⋯ Total cost of RDP group was higher than that of LDP group ((80 563.7±10 641.8) yuan vs. (57 792.8±8 943.0) yuan, t=4.515, P<0.01). Conclusions: Both RDP and LDP are safe and feasible procedures. RDP is more expensive, but RDP is associated with significantly less blood loss and higher spleen-preserving rate, which is more suitable for the non-malignant diseases of pancreatic body and tail with an expectation of splenic preservation.

[High definition MRI rectal lymph node aided diagnostic system based on deep neural network].
Objective: To investigate the clinical significance of high definition (HD) MRI rectal lymph node aided diagnostic system based on deep neural network. Methods: The research selected 301 patients with rectal cancer who underwent pelvic HD MRI and reported pelvic lymph node metastasis from July 2016 to December 2017 in Affiliated Hospital of Qingdao University. According to the chronological order, the first 201 cases were used as learning group. ⋯ There were 772 images having identical diagnostic results of lymph node location and number of metastases with the two methods. Compared with manual diagnosis, the AUC of the intelligent platform was 0.886 2, the diagnostic time of a single case was 10 s, but the average diagnostic time of doctors was 600 s. Conclusion: The HD MRI lymph node automatic recognition system based on deep neural network has high accuracy and high efficiency, and has the clinical significance of auxiliary diagnosis.
