Objective To investigate the best management in treating relapsed biliary calculi after endoscopic sphincterotomy (EST).Methods The clinical data of 96 patients with relapsed biliary calculi after EST in our hospital from February 1999 to February 2009 were retrospectively analysed. The patients were grouped into two groups by the size of calculi under magnetic resonance cholangiopancreatography: surgical group (the size of calculi was bigger than 1.0 cm) in 79 cases and non-surgical group (the size of stone was smaller than 1.0 cm and the patients were performed EST again) in 17 cases. The relapsed biliary calculi rate between two groups were compared. Results In the surgical group, the 79 patients (82.29%) were performed common bile duct exploration, transected common bile duct and choledochojejunostomy with Roux-en-Y anastomosis. In the non-surgical group, the 17 patients (17.17%) were performed EST again. The relapsed biliary calculi rate was 2.63% in the surgical group, 70.59% in the non-surgical group. There was marked difference in the relapsed biliary calculi rate between surgical group and non-surgical group (Plt;0.05). Conclusion The operation treatment is the best way for relapsed biliary calculi after EST, and has good curative effect. The best manner of operation treatment is common bile duct exploration, transected common bile duct and choledochojejunostomy with Roux-en-Y anastomosis.

an easy and safe technique, liver transection by curettage and aspiration (LTCA), using an efficient instrument, Peng’s multifunction operative dissector (PMOD) is described in this article. A comparison brtween two groups of patients undergonig hapatectomy were made. One group were operated on with LTCA; the other group with forceps crush method (FCM). Results: the amount of blood loss with LTCA was only half of that with FCM. The time needed for liver transection with OTCA was 40 percent shorter than that with FCM. After comparision of a variety of currently available techniiques and surgical instruments, it is concluded that LTCA is superior to all other techniques, while PMOD is superior to CUSA.
Objective To study the clinical feasibility of invasive mechanical ventilation with bilevel positive airway pressure（BiPAP） non-invasive ventilator in the stable patients needing prolonged mechanical ventilation.Methods Eleven patients with respiratory failure admitted in intensive care unit（ICU）of our department，who needed prolonged mechanical ventilation，between Jun 2004 and Nov 2007 were enrolled in the study and followed until death or Jan 2008.The arterial blood gas analysis data，length of stay(LOS)，LOS after changing to BiPAP non-invasive ventilator（Synchrony，Harmony，RESPIRONICS，VPAP III ST-A，RESMED），survival time after discharge(or fulfilled the discharge standards) were reviewed retrospectively.Results The settings of inspiratory pressure，expiratory pressure and respiratory rate of non-invasive ventilation were 21.3 (16-26) cm H2O，4 cm H2O，and 16 min-1，respectively.The LOS (or up to the discharge standard) was (91.5±50.2) days.The LOS (or up to the discharge standard) after changing to BiPAP ventilator was (23.5±12.2) days.The mean survival time after discharge (or up to the discharge standard) was (353.1±296.5) days.Four patients were still alive up to the end of the study.The arterial pH，PaCO2，PaO2，and SaO2 were not significant different before and after changing to BiPAP ventilator.Conclusion The mechanical ventilation with BiPAP non-invasive ventilator via tracheotomy tube is an alternative choice for stable patients needing prolonged mechanical ventilation.
Objective To compare the efficacy and safety of different airway humidification methods in patients with tracheotomy in weaning process. Methods Twelve patients with tracheotomy in the medical intensive care unit ( MICU) of the First Affiliated Hospital of Sue Yat-sen University fromSeptember 2008 to August 2009 were enrolled in which 45 case /times weaning tests in three different humidification ways were performed( 15 cases in each group) . Wet square gauze method was used in group A and traditional intermittent wet fluid drip method was used in group B. In group C, MR850 humidifier device, RT200 Venturi tube and T tube device were used to perform humidification. Comparisons were carried out between the three groups on sputum viscosity, comfort of patients before and after humidification, length of weaning time, frequencies of irritating coughs and phlegm formation during test period. Sputum viscosity was evaluated by airway secretion score ( AWSS) .Results There was no significant difference of sputum viscosity assessed by AWSS in group A before and after humidification( P gt; 0. 05 ) while AWSS was significantly increased in group B and group C ( P lt;0. 01) , implied that sputum viscosity was significantly lower than that of group A ( P lt;0. 05) . The scores of patients’comfortwere 3. 0 ±0. 4, 5. 0 ±1. 2, and 8. 0 ±1. 7 in groups A, B, and C respectively which mean that the patients in group C felt more comfortable than those in group A and group B ( P lt;0. 01) . Cough frequencies of groups A, B and C per hour were 0. 8,2. 6,and 0. 4 times/hour respectively in which the frequency of group B was significantly higher than those of group A and group C ( P lt;0. 01) . The frequency of phlegm formation in group A was 7 times in 15-times offline record, which was significantly higher than those in group B and group C ( P lt;0. 01) . Conclusions For the patients with tracheotomy in weaning process, MR850 humidifier device, RT200 Venturi tube and T tube device for humidification is superior in reducing sputum viscosity and phlegm formation, improving patient comfort, and reducing the occurrence of irritating cough.

Abstract： Objective To find out goodness and weakness by comparing totally thoracoscopic surgery （TTS）and median sternotomy （MS）with cardiopulmonary bypass for pediatric open heart operation. Methods One hundred and fortyseven patients with ventricular septal defect(VSD) and atrial septal defect(ASD) were randomly divided into two groups according to operative methods, TTS group: patients were operated by totally thoracoscopy; MS group: patients were operated by median sternotomy with cardiopulmonary bypass. The clinical records from two groups were compared on operative effect, complications, hospitalization, ventilation time,variations of main data of blood routine test, drainage of pleura cavity, blood loss and transfusion, and pulmonary function. Results There were no death in two groups. There was VSD residual leak the same day after operation which was cured by TTS in one patient of TTS group. There was one case which bleeding was stopped by second operation in MS group. Followup visit were made to 41 patients for 3 months, no heart murmur was detected. The ultrasonic cardiography (UCG) showed that correcting of VSD and ASD were good and had no residual leak. The hospitalization,aortic clampping time, ventilation time and variations of main data of blood routine test, drainage of pleura cavity, blood transfusion and blood loss in TTS group had no significant difference to those in MS group (Pgt;0.05). Operating times was longer in TTS group than that in MS group, while stays in the intensive care unit were shorter in TTS group than that in MS group (Plt;0.01). Preoperative and 3 months postoperative pulmonary function of both teams had no statistically significant difference in two groups (Pgt;0.05). Conclusion TTS is a safe and effective method to pediatric VSD and ASD as MS is.
