OBJECTIVETo investigate the traditional VSD from one-way improvement to two-way suction drainage, meet the needs of clinical treatment, and prevent bung tube.

METHODSOne-way multi-side hole drainage tube of the traditional VSD was modified for bi-directional multi-side hole drainage, seaweed salt hydration alcohol polyethylene foam, Semipermeable membrane paste of Polyurethane and acrylic remains the same with that of the traditional VSD.

RESULTSThe applications of bi-directional multi-side hole drainage pipe can reduce the rate of plugging, rinse the complex and infection wound, create a physiological moist healing environment, and promote wound healing.

CONCLUSIONSThe improved VSD can reduce the failure rate and increase the therapeutic effect.

Percutaneous drainage of 4 pancreatic abscesses and 5 pancreatic pseudocysts was performed under the guidance of ultrasonography or fluoroscopy. Clinical inprovement following the percutaneous drainage enabled surgical procedure in 2 of 4 pationts with pancreatic abscesses and obviated surgery in the other 2. In patients with pancreatic pseudocysts, recurrence have nat been observed for the last 3 years. Percutaneous drainage is a safe and effective procedure and could be the method of choice in the management of pancreatic pseudocyst that is symptomatic and enlarging. Percutaneous drainage could play a significant role in the management of the patients with pancreatic abscess.

Percutaenous transhepatic biliary drainage (PTBD) is widely used to control cholangitis, sepsis, or jaundice caused by biliary tree obstruction. The PTBD tract can be used in percutaneous biliary stone extraction in pre-or post-operative state when ERCP is failed or operation is contraindicated. We performed 16 cases of percutaneous transhepatic biliary stone removal. Locations of biliay stones are combined intrahepatic and extrahepatic in 8 cases (50%), only extrahepati in 7 cases (44%), and only intrahepatic in 1 case (6%). The number of stones was single in 6 cases and multiple in 10 cases. Over all success rate was 81% (13/16), 93% (14/15) in extrahepatic stones and 78% (7/9) in intrahepatic stones. In 5 of 6 cases, complete stone removal was impossible due to marked tortuosity of T-tube tract or peripherally located stones, complete removal of biliary stones was achieved via a new PTBD tract. No significant pre-or post-procedure complication was occured. Percutaneous removal of biliary stones via PTBD tract is an effective and safe alternative method in difficult cases in the menagement of biliary tract stones.

OBJECTIVETo compare and evaluate the effectiveness of two kinds of medical drainage bag.

METHODS206 patients were randomly divided into two groups each of which consisted of 103 patients. All the data including four indices, such as the time required to replace the drainage bags, the incidence of the bags detached, draining fluid splashing rates during the replacement of the bags, patient and medical staff satisfaction, were collected and analyzed statistically.

RESULTSThe time required to replace the drainage bags, the incidence of the bags detached and draining fluid splashing rates during the replacement of the bags of the experimental group were significantly lower than those of the control group (P < 0.05), while the patient and medical staff satisfaction were significantly higher than those of the control group (P < 0.05).

CONCLUSIONIt is convenient, quick and time and effort saving to use the neotype medical drainage bags. Hence, the use of neotype medical drainage bags could help to improve the work efficiency, effectively prevent occupational injuries and protect health care workers.

OBJECTIVETo assess the efficacy and safety of bilateral versus unilateral biliary drainage in malignant hilar obstruction.

METHODSTopically relevant studies,regardless of randomized or observational design, were searched for in PubMed, EmBase and the Cochrane Library database. Risk ratios (RRs) with 95% confidence intervals (CIs) were calculated to compare the effect of the two treatments.

RESULTSThree randomized trials and 7 observational studies were included, involving 894 patients with malignant hilar obstruction. The meta-analysis assessment of primary outcomes showed that the stent patency rate was better in bilateral drainage than in unilateral drainage (Rr=2.03,95% CI [1.16-3.56], P=0.01), but there were no significant differences in successful drainage rate (Rr=1.07,95% CI [0.97-1.18], P=0.20) and patient survival rate (Rr=-0.16,95% CI [-0.40-0.08], P=0.20). In the analysis of secondary outcomes,there were also no significant differences in the technical success rate (Rr=1.05,95% CI [0.98-1.17], P=0.34),the early complication rate (Rr=1.15, 95% CI [0.75-1.76], P=0.52), late complication rate (Rr=1.09,95% CI [0.75-1.60], P=0.60) and 30-day mortality rate (Rr=0.68,95% CI [0.38-1.23], P=0.20).

CONCLUSIONAlthough the cumulative stent patency was better for the bilateral than the unilateral drainage approach, based on the available data, there is not enough data to support bilateral drainage for malignant hilar obstruction. Well-designed randomized controlled trials are necessary to confirm it.

Many difficult problems are encountered in the treatrnent of infected nonunion of long bone. To solve these difficult fractures, authors adopted an active approach-thorough debridement of the infected and necrotic soft tissue and bone, rigid internal fixation with autogenous cancellous bone graft and opening of the wound to ensure continuous drainage until union of the fracture. Authors treated 28 cases of infected nonunions with this method from Mar. 1980 to Feb. 1989, and the results are as follows ;1. Femur(54%) and tibia(43%) were most frequently involved sites. 2. Most of the cases(86%) were treated by rigid internal fixation and cancellous bone graft. 3. In most cases(64%), infection was controlled spontaneously by the time of bony union, but in 5 cases which showed persistent drainage, implant removal controlled the problem, and residual soft tissue and bony defect were solved by Papineau's technique or musculocutaneous flap. 4. Revision was required in 5 cases(18%) because of insercure fixation. 5. Union could be obtained in average 4.8 months, and infection could be controlled in all except 1 case.

Percutaneous transhepatic biliary drainage was successfully made 20 times on 17 patients of obstructivejaundice for recent 1 year since June 1981 at department of radiology in Seoul National University Hospital. Thecauses of obstructive jaundice was CBD Ca in 13 cases, metastasis in 2 cases, pancreatic cancer in 1 case and CBDstone in 1 case. Percutaneous transhepatic biliary drainage is a relatively easy, safe and effective method whichcan be done after PTC by radiologist. It is expected that percutaneous transhepatic biliary drainage should bedone as an essential procedure for transient or permanent palliation of obstructive jaundice.

Endoscopic transpapillary biliary drainage is the current standard of care for unresectable hilar malignant biliary obstruction (MBO) and bilateral metal stent placement is shown to have longer patency. However, technical and clinical failure is possible and percutaneous transhepatic biliary drainage (PTBD) is sometimes necessary. Endoscopic ultrasound-guided biliary drainage (EUS-BD) is increasingly being reported as an alternative rescue procedure to PTBD. EUS-BD has a potential advantage of not traversing the biliary stricture and internal drainage can be completed in a single session. Some approaches to bilateral biliary drainage for hilar MBO under EUS-guidance include a bridging method, hepaticoduodenostomy, and a combination of EUS-BD and transpapillary biliary drainage. The aim of this review is to summarize data on EUS-BD for hilar MBO and to clarify its advantages over the conventional approaches such as endoscopic transpapillary biliary drainage and PTBD.
