Objective To investigate the applicetion value of combined ultrasonic scalpel in laparoscopic cholecystectomy(LC).Methods 140 patients with acute and chronic cholecystitis,gallbladder stone patients,received intraoperative ultrasound combined electrosurgical knife,suction devices auxiliary red line LC.The clinical effects were observed.Results 138 cases were completed cholecystectomy.Blood loss ( 8.16 ± 1.85 ) ml,operation time(38.13 ±4.35) min,Postoperative hospital stay(3.25 ± 1.18)d,4 cases of intraoperative rupture of the gallbladder,Hepatobiliary burns in 1 case,2 cases because of dense adhesions around the gallbladder and gallbladder more extensive anatomical triangle unclear laparotomy.Conclusion The rational use of combined high-frequency ultrasonic scalpel knife,suction devices auxiliary red laparoscopic cholecystectomy,surgical conditions that meet medicalrecords,are safe and reliable,quicker recovery can be achieved by minimally invasive medical treatments.

Objective To explore the surgical techniques and clinical indication of laparoscopic splenectomy combined with cholecystectomy.Methods The clinical data from two patients underwent laparoscopic splenectomy combined with cholecystectomy were retrospectively analyzed.Results Two patients have been performed splenectomy with cholecystectomy successfully under laparoscopy.The operation time of laparoscopic splenectomy was 90 min and 100min.Blood loss was 700ml and 800ml.Two patients were discharged 5 days postoperatively without any complications of bleeding,infection,pancreatic leakage.Conclusion The key surgical technique in the laparoscopic splenectomy combined with cholecystectomy was to control the splenic artery and vein according 1o different spleen anatomy.Non-acute inflammatory gallstone with surgical splenic diseases was considerel the clinical indications and the aseptic techniques and the sequence should be taken seriously during LS + LC.

Objective To investigate the feasibility and clinical results under laparoscopic resection of colorectal cancer.Methods Clinical data of 17 colorectal cancer patients with laparoscopic resection from October 2009 to September 2011 were analyzed.Results There were 16 cases of successful completion of laparoscopic surgery,conversion to open surgery in 1 case.Postoperative of incomplete intestinal obstruction and rectal vaginal fistula are each 1 case.Oncology did not occur metastasis through puncture holes in postoperative follow-up up to 2 years.Conclusion Laparoscopic resection of colorectal cancer should be widely applied,and it had more advantages such as less trauma,safety,recover quickly,consistent with the effect of laparotomy.

Objective:To evaluate the value of the preoperative T staging of laryngeal and hypopharyngeal cancers by MRI at high field strength(1.5T).Methods:The MRI data of 36 cases of primary laryngeal or hypopharyngeal cancers were retrospectively staged,and compared with the clinical and postsurgical pathologic staging.Results:The accuracy of staging in each T stage of laryngeal and hypopharyngeal cancers was:T1:92%;T2:86%;T386%;T4:100% by MRI vs.T1:100%;T286%;T3:57%;T4:22% by clinic/laryngoscope.The total accuracy of MRI and clinic/laryngoscope respectively was 92% vs 69%.P＜0.05.Conclusion:MRI can correctly depict the original tumors site and invasion extension of laryngeal and hypopharyngeal cancers by comparing T1WI and T2WI with multiplanar,consequently improve the accuracy for staging significantly.
