PURPOSE: Effective myocardial reperfusion after primary PCI for an AMI in lesions with a thrombus is limited by distal embolization and the slow/no reflow phenomenon. We evaluated the efficacy of a thrombus reduction technique using an export aspiration catheter for thrombosuction during primary PCI. MATERIALS AND METHODS: We analyzed 62 patients with AMIs who underwent primary PCI and had a thrombi burden during thrombosuction using an EAC (EAC group; n=31) or without thrombosuction (control group; n=31). RESULTS: Thrombosuction with an EAC was performed safely in all the patients in EAC group without any complications. After the PCI, restoration to a TIMI flow grade 3 was significantly more frequent in the EAC group (26/31 vs. 20/31, p < 0.05). However, the TIMI perfusion grade did not differ between the two groups. Further, the corrected TIMI frame counts were lower in the EAC group (23.9 ± 15.1 vs. 34.8 ± 22.5, p < 0.05). Although there was no statistical significance, a greater incidence of distal embolization was observed in the control group (16.1%, 5/31) as compared to the EAC group (0/31) (p= 0.056). However, the incidence of major adverse cardiac events at 1 and 6 months did not differ between the two groups. CONCLUSION: For AMIs, thrombosuction with an EAC before or during PCI is a safe and potentially effective method for restoration of the coronary flow.

BACKGROUNDLaparoscopic surgery is advantageous for minimal invasiveness and rapid postoperative recovery. Since the use of laparoscopic hepatectomy in liver resection in the 1990s, it has been performed in a few institutions worldwide. Lack of efficient and safe techniques for liver transaction is the major obstacle preventing from its further development. We developed a new technique for laparoscopic hepatectomy by curettage and aspiration in 1998. In this paper we analyze the clinical outcomes of this technique after 7 years of practice.

METHODSAltogether 59 consecutive patients underwent laparoscopic hepatectomy by curettage and aspiration from August 1998 to January 2005 at our institution. These patients included 33 males and 26 females, with a mean age of 47 years. For liver transection laparoscopic Peng's multifunctional operative dissector (LPMOD) was used. Lesions included malignant liver tumors in 19 patients, benign liver tumors in 17, intrahepatic calculus in 18, and other liver lesions in 5. Procedures included local resections in 30 patients, left lateral segmentectomy in 28, and right hemihepatectomy in 1.

RESULTSLaparoscopic operation was completed in 57 patients. Two patients (3.4%) had the operation converted to laparotomy. The mean operating time was 143 minutes and the mean intraoperative blood loss was 456 ml. The mean length of postoperative hospital stay was 7 days. Complications occurred in 2 patients (3.4%), and there was no perioperative death.

CONCLUSIONLaparoscopic hepatectomy by curettage and aspiration is efficient and safe for liver resection.

AIMTo discuss the merits of "tubes treatment" for esophageal fistula (EF).

METHODSA 66-year-old female who suffered from a bronchoesophageal and esophagothoratic fistula underwent a successful "three tubes treatment" (close chest drainage, negative pressure suction at the leak, and nasojejunal feeding tube), combination of antibiotics, antacid drugs and nutritional support. Another 55-year-old male patient developed an esophagopleural fistula (EPF) after esophageal carcinoma operation. He too was treated conservatively with the three tubes strategy as mentioned above towards a favorable outcome.

RESULTSThe two patients recovered with the tubes treatment, felt well and became able to eat and drink, presenting no complaint.

CONCLUSIONTubes treatment is an effective basic way for EF. It may be an alternative treatment option.

PURPOSE: Glass particle contamination of the contents of single-dose glass ampules can occur upon opening. Different aspiration techniques, different sizes of needles, different sizes of ampules, and different cutting methods were studied to determine if they had any effect on glass particle contamination. METHOD: Different aspiration techniques(with filter, without filter), different sizes of needles(18G, 25G), different sizes of ampules(2ml, 20ml), and different cutting methods(with cotton, without cotton) were evaluated. METHOD: Twenty ampules were randomly assigned in each group. Three slides containing glass particles for each ampule were made and counted under a microscope by 3 study blind persons. RESULT: The number of glass particle contamination is much less when using a filter rather than without a filter. The number of glass particle contamination is much less when using a 25G needle rather than on 18G needle. The number of glass particle contamination is much less when using 2ml ampules rather than 20ml ampules. The number of glass particle contamination is much less when using cotton rather than without cotton. CONCLUSION: It was shown that using a filter, a small size needle, smaller sized ampules and using cotton when cutting the ampule will decrease the risk of parenteral injection of glass particles.

BACKGROUNDDifferent feasible and safe thrombectomy and distal protection devices have been used in clinical practice. The efficiency and safety of adjunct thrombectomy using Diver CE device (Invatec, Italy) versus Guardwire Plus device (Medtronic, USA) before percutaneous coronary intervention (PCI) were compared in patients with acute inferior ST-segment-elevation myocardial infarction (STEMI) for less than 12 hours, thrombolysis in myocardial infarction (TIMI) flow grade 0 to 1, and total occlusion of the proximal right coronary artery (= 3 mm in diameter) in a prospective randomized single-center study.

METHODSThe primary end point was the magnitude of ST-segment resolution (STR) (> 70%) measured immediately, 90 minutes and 6 hours after PCI, myocardial blush grade and slow flow or no-reflow. Secondary end points were left ventricular end-diastolic volume (LVEDV), left ventricle ejection fraction (LVEF) and major adverse cardiac events (MACEs) including death, myocardial infarction, target vessel revascularization and stroke at 30 days.

RESULTSA total of 122 patients were equally divided into Diver CE group and Guardwire Plus group, which were comparable by age ((60 +/- 14) years vs (60 +/- 13) years), male (82% vs 84%), diabetes (31% vs 28%), previous coronary artery disease (25% vs 23%), onset-to-angiogram ((350 +/- 185) min vs (345 +/- 180) min), and use of glycoprotein IIb/IIIa inhibitor (11% vs 13%). The magnitude of ST-segment resolution was similar in the two groups as ST-segment resolution > 70% (57% vs 59%; P > 0.05). Similar slow flow/no-reflow rates were observed in the Diver CE group (8%) and the Guardwire Plus group (7%). TIMI flow grade 3 was obtained in 95% vs 97% patients, respectively (P > 0.05). Myocardial blush grade 3 was similar (70% vs 72%; P > 0.05). Thirty-day clinical outcome was comparable (LVEF, 0.54 +/- 0.12 vs 0.53 +/- 0.11; death, 3% vs 3%; myocardial infarction, 2% vs 0%; and target vessel revascularization, 2% vs 2%; P > 0.05, respectively).

CONCLUSIONSRemoval of thrombus burden with the Diver CE catheter before stenting leads to similar improvement of myocardial reperfusion in patients with inferior STEMI and total occlusion of the proximal right coronary artery (= 3 mm in diameter) compared with the Guardwire Plus device, as illustrated by a reduced risk of distal embolization and improved ST-segment resolution.

OBJECTIVE: To compare the diagnostic value of sterility sputum aspirating tube with bronchoalveolar lavage in mechanically ventilated patients with lower respiratory infection. METHODS: Sixty-four mechanically ventilated patients with lower respiratory infection were selected to collect respiratory passage secretion to analyze the etiology and to evaluate the diagnostic value by using sterility tube aspirate sputum and bronchoalveolar lavage. RESULTS: The positive rate of sterility tube aspirate sputum and bronchoalveolar lavage was 71.88% and 78.13%, respectively, with no statistical difference between the 2 groups (P>0.05). The consistency rate was 81.25% for the 2 methods. CONCLUSION Sterility sputum aspirating tube can not only acquire accurate pathogen, provide evidence to select sensitive antibiotics in clinical practice, but also is a simple practice, safe and economical method for patients with lower respiratory tract infection and mechanical ventilation.
