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.

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.

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.

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.

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.

OBJECTIVE: To determine the clinical value of laparoscopic cystogastrostomy in the treatment of pancreatic pseudocyst. METHODS: Twenty-one patients with pancreatic pseudocyst received total laparoscopic cystogastrostomy. The data on intra-operative bleeding, operative time, post-operative time to get out of bed, time of first flatus/bowel motion, complication and duration of hospital stay were observed and analyzed retrospective1y. RESULTS: Twenty-one patients were successfully carried out the laparoscopic surgery. The average operation time was 90(62-120) min. The blood loss was less than 100 mL in all patients. The average time of hospital stay was 8 d. After 12-18 month follow-up, all patients recovered smoothly without any complication. CONCLUSION Total laparoscopic cystogastrostomy with the posterior approach is a feasible, safe and minimal invasive procedure for pancreatic pseudocyst, which can be recommended to the clinical application.

BACKGROUND AND OBJECTIVES: Recently, canal down mastoidectomy tends to be more frequently selected for complete eradication of the lesion and prevention of recurrence. Therefore, the problems attendant to the open mastoid continue to be of concern. Although various techniques have been used to solve the cavity problems, no single procedure has yet been devised that entirely accomplished this purpose. We evaluated the effects of partial mastoid obliteration using inferior based musculoperiosteal flap and autogenous conchal cartilage chips. MATERIALS AND METHODS: Twenty four cases were performed with mastoid obliteration using inferior based musculoperiosteal flap and autogenous conchal cartilage chips obtained from meatoplasty. There were 11 cases for control which were performed with canal down mastoidectomy without obliteration. We compared these two groups in the duration of epithelialization, accumulation of debris, presence or absence of drainage, shape of remodeled canal and caloric response and evaluated survival or atrophy of flap and absorption of cartilage chips. RESULTS: Obliteration group showed more rapid healing and epithelialization and less accumulated epithelial debris. Atrophy of flap or absorption of cartilage was not observed. There was no draining ear but vertigo with nystagmus on caloric stimulation developed in both groups. CONCLUSION: This partial mastoid obliteration technique used easy and quick application instead of complete restoration of canal wall, and it may be also valuable in providing rapid epithelialization and reducing mastoid bowl volume with relatively round canal shape. Furthermore, epitympanic obliteration using cartilage chips may be an effective method to prevent formation of attic retraction pocket.

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.
