OBJECTIVE: To explore the diagnostic role of computed tomographic dacryocystography (CTDCG) in lacrimal path damage and provide operative approach guidance for the endoscopic transnasal dacryocystorhinostomy (DCR). METHOD: Twenty-eight cases with lacrimal path damage underwent CTDCG. The following reconstruction techniques including volume rendering (VR), multiple planar reconstruction (MPR), maximum intensity projection (MIP) and three-dimensional reconstruction (3-d R) were done on the real-time workstation. The morphology of dacryocyst, displacement fracture of the lacrimal fossa (FS) and the relationship between the uncinate process (UP) and the FS were observed. The thickness of inner walls of anterosuperior and posteroinferior aspects of lacrimal fossa was measured. RESULT: The morphology of dacryocyst, the displacement fracture of the lacrimal fossa and the block site of the lacrimal passage could be displayed clearly by CTDCG with the following reconstruction techniques including VR, MPR, MIP and 3-d R, 6 cases of canaliculus obstruction, 14 cases of lacrimal sac obstruction, 8 cases of lacrimonasal duct obstruction were showed. Meanwhile the relationship between the UP and the FS could also be showed clear. The average bony thickness of the anterosuperior part of FS was (2.96 +/- 0.30) mm, while the bony thickness of the posteroinferior half was (0.02 +/- 0.005) mm, and the distance between the top and bottom of dacryocyst to the operculum of the middle turbinated (OMT) are (6.80 +/- 1.50) mm, (4.00 +/- 1.80) mm respectively (P < 0.05). CONCLUSION The morphology of dacryocyst, the displacement fracture of the lacrimal fossa, block site of the lacrimal passage and the relationship between the UP and FS can be clearly displayed by CTDCG, which provide operative approach guidance for the endoscopic transnasal dacryocystorhinostomy.

ObjectiveTo investigate the influences of routine-dose loratadine on the positive patch test reaction to nickel sulfate.MethodsA double-blind,controlled and randomized study was carried out.A total of 121 patients with a positive patch test reaction to nickel sulfate were divided into two groups to receive loratadine 10 mg (experimental group,n =61 ) or placebo (control group,n =60) once daily for 14 days.The patch testing of nickel sulfate was performed on day 11,and clinical evaluation of the test was carried out on day 14 after the start of treatment.The intention to treat population was used for data analysis.ResultsNo changes were observed in the intensity of patch test reaction to nickel sulfate in 55 patients in the experimental group or 53 patients in the control group,and there was no significant difference between the two groups in the percentage of patients showing changes in the intensity of patch test reaction(9.8％ vs.11.7％,x2 =0.11,P ＞ 0.05).ConclusionThe routine-dose loratadine has no inhibitory effect on the intensity of skin patch test reaction to nickel sulfate.

Objective To evaluate the feasibility and efficacy of laparoscopic treatment of hepatic hemangioma. Methods The clinical data of 27 patients who received laparoscopic treatment of hepatic hemangioma from November 2003 to October 2009 were retrospectively analyzed. The hepatic inflow to the liver or to a hemiliver was temporarily blocked using a Pringle manoeuvre with a self-invented laparoscopic blocker at the porta hepatis or at the pedicle to the relevant hemiliver. The Electriccautery and ultracision were used for liver transaction. Results Laparoscopic treatment of hepatic hemangioma was successfully performed in 25 patients. Conversion to laparotomy was required in two (8%) patients for uncontrollable bleeding. There were no major postoperative complications and no mortality. The mean tumor diameter was (6.34±2. 17) cm. The operating time was ( 105.21 ±72.76)min. The time of hepatic inflow block was (10. 17±12. 21)min. The blood loss was (115. 5±212.14)ml. The volume of blood transfusion was (0. 87 ± 1.45)U. The volume of postoperative drainage was (112.60±201.03)ml. The time taken to return to normal activity was (2. 0±0. 8) days.The length of postoperative hospital stay was (5.5±2.4) days. The length of total hospital stay was (12. 5 ±5.3) days. The total cost was RMB10041.6±8678. 7. Conclusion In selected patients, laparoscopic treatment of hepatic hemangioma was safe and feasible.

Objective To study the feasibility and safety of laparoscopic anatomical liver lobectomy for liver tumor. Methods The feasibility and therapeutic effect of laparoscopic anatomical liver resection on 67 patients were analyzed in our hospital from January 2005 to February 2010. Results Laparoscopic anatomical liver lobectomy was carried out successfully on all the patients. The operative time was 50.6± 16.2 min and the blood loss was 220. 8±76.5 ml. We did not use Pringle's manoeuvre. There was no postoperative complication. The patients were able to be ambulated out of bed within 24 hours and they started to take in food 1-3 days after surgery. The mean hospital stay was 5-7 days after surgery (mean 6.6±1.1 d). The total hospital cost was 30767.4±150. 1 Yuan. Conclusions Laparoscopic anatomical liver resection is feasible and safe. It has the advantages of minimal trauma and quick recovery for tumors located superficially, in the left liver, and in the inferior part of the right liver. Clinically, it should be used more widely.

Objective To compare the feasibility and safety of laparoscopic versus open hepatectomy.Methods The data of 165 patients who underwent laparoscopic hepatectomy were compared with 170 patients who underwent open hepatectomy in our hospital from November 2002 to December 2010.Results Laparoscopic hepatectomy was successfully carried out in 159 patients and 6 patients were converted to open operation because of intra-operative hemorrhage.The 170 patients in the open operative group had open hepatectomy successfully carried out.The hospital stay and cost in the laparoscopic group(7.6±1.3 d,31767.4±220.1(￥))were less than the open operation group(14.6±3.3 d,35127.3±392.2(￥))(t=-12.657,P＜0.001; t=-78.859,P＜0.001).There was no significant difference in Pringle's manoeuvre time,blood loss and postoperative complications(20.6 ±8.5vs.18.6±6.5 min,t=2.108,P=0.068),(420.8±76.5 vs.395.9±96.1 ml,t=2.157,P=0.063),(0 vs.4 cases,t=2.011,P=0.156))between the 2 groups.The operative time in the laparoscopic group was significantly longer than the open group(59.6 ± 12.2 vs.42.7 ± 22.6 min)(t=6.941,P＜0.001).Conclusions Laparoscopic hepatectomy is feasible and safe.It has the advantages of having less trauma and quicker recovery for tumors which were located superficially in the left liver and in the inferior part of the right liver.The operative time was longer than open hepatectomy,but there was no significant difference between the 2 groups in Pringle's manoeuvre time,blood loss and postoperative complications.The hospital stay and total hospital cost in the open operation group were higher than the laparoscopic hepatectomy group.
