There are some limits and irrationality in practical application of the clause 3.1, 3.2, 4.4.2, 4.5.2, 4.9.1 of YY 0672.1-2008 as the industry standard for laparoscopic trocar. This paper puts forward some opinion and advice.

Caudate lobectomy is still a great challenge for surgeons due to unique anatomy of caudate lobe.A 38-year-old male patient with a huge recurrent hepatic cancer (diameter =16 cm) in caudate lobe received caudate lobectomy with portal triad and inferior vena cava clamping.The operation was paused due to hemorrhage (volume of blood loss =1000 ml).After heat preservation and blood transfusion,the caudate lobectomy was completely removed with inferior vena cava clamping.The patient gradually recovered,and no tumor recurrence was detected during the follow up (14 months).Caudate lobectomy could be safely carried out under the condition of accurate preoperational estimation,clear indication for surgery and precise hepatectomy.

ObjectiveTo investigate the clinical features of borderline ovarian tumor (BOT).MethodThe clinical features, clinical stage, malignant potential, pathological type, the positive rate of serum CA125 were analyzed in 60 patients with pathological diagnosis of BOT. ResultsSerous cystadenoma was the main pathological type, accounted for 60.0％ (36/60). The occurrence of focal canceration in serous cystadenoma[22.2％ (8/36)]was higher than that in mucinous cystadenoma[5.3％(1/19)](P＜ 0.05). The positive rate of CA125 was 51.7％(31/60). The positive rate of CA125 in BOT with　micro-dip or focal canceration[65.0％(13/20) and 81.8％(9/11)]was higher than that in simple BOT [31.0％(9/29)](P＜O.05),but there was no significant difference between BOT with micro-dip and BOT with focal canceration (P＞ 0.05 ). ConclusionsBOT is low malignant potential and preoperative diagnosis is difficult because of the typical clinical symptoms. CA125 is not sensitive to pure BOT. Women of childbearing age should regularly check for ovarian tumor by ultrasonography and preoperative serum CA125 test can be combined with micro-dip on the BOT and those made with preoperative focal predict cancer diagnosis. Aggressive surgical treatment is necessarily as soon as possible and rapid intraoperative pathological examination to reduce cancer risk.

Objective To seek the least damage to tooth structure and method of treatment to obtain the minimal microleakage.Methods 600 posterior teeth in vitro constant,according to the random number table method,were divided into 6 groups:A,B,C,D,E,F,l00 cases in each group.The pigmentation of deep pit and fissure or pit and fissure caries of the suspicious isolated human premolar were selected as observation objects,respectively.a Er:YAG laser,a high-speed diamond bur and clean cup brush were used to prepare for isolated anterior molar occlusal pit and fissure.And the performance of each sample was filled with light curing composite resin and fluid,Six different filling conditions of filling body and fissure between microleakage and bonding interface were observed by dye penetration method and scanning electron microscopy.Results The efficiency of F group was 99％,which was significantly higher than 87％ of C group (χ2 =5.84,P ＜0.05),55％ of D group(χ2 =7.21,P ＜0.05) and 87％ of E group (χ2 =11.65,P ＜ 0.05).The efficiency of C group was 87％,which was significandy higher than 43％ of A group (χ2 =3.97,P ＜ 0.05) and 61％ of B group (χ2 =8.35,P ＜ 0.05).The efficiency of B group was 61％,which was significantly higher than 43％ of A group (χ2 =6.25,P ＜ 0.05).Conclusion Er:YAG laser with fluid resin filling is the most effective way for the clinical treatment of pit and fissure deep narrow,already susPicious pit and fissure caries pit and fissure sealant failed teeth.

Biliary cystic tumors (BCTs) are rare cystic tumors and are accounted for less than 5％ of liver cysts.BCTs are very common in middle-aged and elderly women,and depend on diagnosis of imaging including papillary projection or multilocular cystic liver mass.BCTs are frequently misdiagnosed due to the absence of specific diagnostic indicators,which should differentiate from diagnosis of hepatic cystic.Complete surgical resection is the first choice for BCTs with a good out-come,in addition to low recurrence.Once recurrence was identified in follow-up,BCTs can be treated by reoperation with a good outcome.
