Objective To investigate the curative effects of laparocopic treatment for cystiduodenal internal fistula. Methods All procedures were conducted under laparoscope. After the exposure of the cholecystic base, trans-cholecystic cholangiography was performed to detect the relations between the cholecyst and neighboring organs. Once the internal fistula was confirmed, the orifice of fistula was closed laparoscopically. Then abdominal drainage, gastrointestinal decompression, and administration of somatostatin were routinely employed. Results In a series of 327 cases of laparoscopic cholecystectomy (LC) with intraoperative cholangiography, a total of 6 cases of cystiduodenal internal fistula were detected, all of which were anatomized and closed successfully under laparoscope. No postoperative hemorrhage or duodenal bile leakage occurred. Conclusions Routine intraoperative cholangiography during LC is beneficial to the detection of the cystiduodenal internal fistula.Effective and reliable management rests upon skillful laparoscopic techniques of dissection and fistula closure, as well as the supportive treatment.

Objective To investigate the effect of sufentanil and midazolam assisted epidural anesthesia for cholecystectomy on sedative effects,visceral pulling reaction and the functions of respiratory and circulatory system.MethodsFourty patients underwent cholecystectomy received informed consent, were randomly allocated to two groups:group A and group B( n =20 each). When the level of epidural block is appropriate,auxiliary medicine infusion was given 5min before the skin incision. In group A,first injection was sufentanil 0. lμg · kg-1 and midazolam 0. 02mg · kg-1 in 1-2 min, then continuous infusion of sufentanil and midazolam was given at the rate of 0. 2μg ·kg-1 · h-1 and 0. 04μg · kg-1 · h-1 respectively,and the infusion was stopped at the time of wound closure. Group B received slow intravenous injection of pethidine 1mg · kg-1 and droperidol 0. 5mg · kg-1. We recorded the differences of SBP、DBP、SpO2 、HR、Ransay score and visceral pulling reaction classification. Results SBP、DBP、HR after anesthesis,were decreased in different degree in the above groups,but there was no statistically significant difference( P >0. 05). According to Ramsay score,in group A there were 3 cases in grade Ⅱ、8 cases in Ⅲ and 9 cases in Ⅳ ,while in group B there were respectively 4 cases in Ⅱ、13 cases in Ⅲ and 3 cases inⅣ. By comparision,the differences had statistical significance ( u = 3.75, P < 0. 05 ); Group A according to visceral pulling reaction classification (0- Ⅲ ), were 9 cases in grade 0,9 cases in Ⅰ , 1 cases in Ⅱ and 1 cases in Ⅲ, while in group B there were respectively 4,5,7 and 4 cases. By comparision, the differences had statistical significance(u = 4. 01,P < 0. 01 ). Conclusion In the cholecystectomy,sufentanil and midazolam assisted epidural anesthesia,could improve the level of sedation ,prevent visceral pulling reaction ,and had a minor interference to respiratory and circulatory function.

Objective To compare the clinical outcomes of percutaneous cannulated lag screws versus posterior buttress plate in the fixation for posterior malleolar fractures.Methods We reviewed the 167 patients who had been treated between January 2010 and December 2014 for ankle fracture involving larger than 25% of the articular surface of the posterior malleolus.They received posterior malleolus fixation with percutaneous cannulated lag screws or with a buttress plate.In the cannulated screw group (84 patients),there were 47 males and 37 females,aged from 23 to 72 years (average,49.7 ±9.1 years),and 39 cases of type B and 45 ones of type C according to the Dennis-Webber classification.In the buttress plate group (83 patients),there were 38 males and 45 females,aged from 31 to 69 years (average,52.3 ± 8.3 years),and 45 cases of type B and 38 ones of type C according to the Dennis-Webber classification.At 6 and 12 months postoperation and the final follow-up,the ankle motion was evaluated using American Orthopaedic Foot and Ankle Society (AOFAS) score and range of motion (ROM).Results The average operation time for the cannulated screw group was significantly shorter than for the buttress plate group (Z =-9.145,P < 0.001).No fracture nonunion,reduction loss or incision infection happened in either group.In the cannulated screw group,we detected malunion with a step-off beyond 2 mm in 5 patients,and penetration of one cannulated lag screw into the tibiofibular syndesmosis in 3 patients.In the buttress plate group,we detected toe flexion contracture in 4 patients,and uncomfortable feeling in ankle motion in 7 patients.At the final follow-up,X-rays and CT scans in the 2 groups showed no obvious post-traumatic osteoarthritis of the ankle.There were no significant differences between the 2 groups regarding the AOFAS scores at 6 and 12 months postoperation and the final follow-up(P > 0.05);the AOFAS scores at the final follow-up for all the patients were significantly different from those at 6 and 12 months postoperation (P < 0.05).At the final follow-up,there were no significant differences between the 2 groups regarding ROMs of dorsal flexion,plantar flexion,varus or valgus (P > 0.05).Conclusions As there are no significant differences between the percutaneous cannulated lag screws and posterior buttress plate in AOFAS score and ROM of the ankle after fixation for posterior malleolar fractures,the 2 fixation methods can both achieve good clinical outcomes.Fixation with cannulated lag screws has advantages of indirect reduction and minimal invasion but also a disadvantage of uncertain quality of reduction;fixation with buttress plates has an advantage of anatomical reduction under direct vision but also shortcomings of relatively large invasion and high cost.
