Artificial conduits, including ureteral stents and catheters, are used widely as drainage tools in the urinary system. However, various bacteria in the urine and long duration of insertion can arouse the biofilm formation on the pipeline surface, which calls for effective antibacterial strategy. In this article, the mechanism of Catheter Associated Urinary Tract Infections (CAUTI) is explained from the perspective of etiology. Then, the biofilm formation conditions and the features of urine are analyzed, the antibacterial agents and approaches suitable for ureteral stents and catheters are introduced and their pros and cons are discussed respectively.

BACKGROUND: Surgical site infection is one of the common postoperative complications of thoracic surgery, and its harm is related to infection degree and location. Light causes local pain, prolonged hospitalization and increased cost. Severe infection can lead to severe infection, even septic shock and life-threatening. Therefore, proper treatment of incision infection can help to promote recovery, reduce the burden of disease and lay a good foundation for further treatment. The traditional surgical treatment of wound infection includes thorough drainage, intensive dressing change and antibiotic use. There are many shortcomings such as long treatment process, ineffective treatment effect and so on. The experience of using vacuum sealing drainage (VSD) in 6 cases of postoperative infection patients in our department is summarized in order to improve the traditional treatment of postoperative infection in patients after thoracic surgery. METHODS: The clinical data of patients with postoperative incision infection or fistula after thoracic surgery in our department were reviewed and summarized. 6 patients treated with VSD material for postoperative infection. The process and final clinical results of them were summarized and discussed. RESULTS: In this study, fever and wound exudation disappeared within 6 h-10 h after VSD use, 5 cases of wound infection were obviously improved, the secretion disappeared and the granulation tissue grew well at the cutting edge of the operation, the second stage operation was performed to close the chest and skin. One patient was seriously infected, and the secretion was still more after VSD removal, reposition VSD device next time, the VSD device was removed 7 d later. The wound infection were obviously improved, the secretion disappeared and the granulation tissue grew well, close the chest and skin second stage. In all 6 patients, the symptoms were relieved, the symptoms improved and the surgical incision healed well. In 2 patients with esophageal cancer, the average operation time was 427.5 min, the average hospitalization time was 40 d, the average number of times of dressing change was 8.5, the average total cost during hospitalization was 111,893.47 yuan patients with chronic empyema, the average operation time was 192.5 min. The average hospital stay was 27.75 days, the average number of times of dressing change was 5.5, and the average total expenditure during hospitalization was 48,237.71 yuan. CONCLUSIONS VSD has a good effect on the treatment of postoperative incision infection patients in thoracic surgery. It can reduce the pain and burden of patients and ensure the quality of life of postoperative infected patients.

OBJECTIVETo explore the efficacy of over-the-scope clip (OTSC) in the treatment of gastrointestinal fistula.

METHODSClinical data of 12 gastrointestinal fistula patients, including 3 internal fistula and 9 external fistula treated with OTSC in our institute from March 2015 to May 2016 were retrospectively analyzed. OTSC was performed when pus was drained thoroughly and intra-abdominal infection around gastrointestinal fistula was controlled, and each patient received one clip to close fistula.

RESULTSThere were 6 female and 6 male patients with mean age of (50.1±12.6) years. The successful rate of endoscopic closure was 100% without complications including bleeding and intestinal obstruction during and after OTSC treatment. According to comprehensive evaluation, including drainage without digestive juices, no recurrence of intra-abdominal infection, no overflow of contrast medium during digestive tract radiography, and CT examination without intra-abdominal abscess, clinical gastrointestinal fistula closure was 91.7%(11/12). There was no recurrence of gastrointestinal fistula during 3 months of follow-up in 11 patients. In the remaining 1 case, the gastric fistula after laparoscopic sleeve gastrectomy recurred one week after OTSC treatment because of intra-abdominal infection surrounding fistula, and was cured by surgery finally.

CONCLUSIONThe endoscopic closure treatment of OTSC for gastrointestinal fistula is successful and effective, and control of intra-abdominal infection around fistula with adequate drainage is the key point.

Eight patients with femoral osteomyelitis were admitted in Lanzhou General Hospital of PLA between July 2012 and July 2015. During the operation the femur was fixed with non-contact locking plate after thorough debridement. Iliac morselized cancellous bones without cortical bone were filled in the bone defect after debridement. The locking plates were placed in the lateral subcutaneous interface superficial to the vastus lateralis muscle. Drainage tubes were routinely placed postoperatively. The surgery was completed successfully in all patients, and the average operation time was (130±10) min (120-150 min). Intravenous antibiotics were administrated for 2 weeks and followed by 4 week-oral antibiotics after the operation in all 8 cases. Drainage tubes remained in situ about 8 days. All patients were followed up for 12-48 months, with an average of (19±7) months. Postoperative X-ray examination showed bone union in 7 cases with an average healing time of (16±5) weeks. One patient failed with relapsed infection, and was later treated with Ilizarov apparatus after secondary debridement. No plate and screw fracture, loose and fixation failure were observed in all 8 cases.

Enhanced recovery after surgery (ERAS) is a patient-centered, surgeon-led system combining anesthesia, nursing, nutrition and psychology. It aims to minimize surgical stress and maintain physiological function in perioperative care, thereby expediting recovery. ERAS theory has been clinically applied for nearly 20 years and it is firstly used in colorectal surgery, then widely used in other surgical fields. However, ERAS is not used commonly in esophagectomy because of its surgical complexity and high morbidity of postoperative complications, which limits the application of ERAS in the field of esophagectomy. In recent years, with the increasing maturation of minimally invasive esophagectomy, attention to tissue and organ protection concept, improvement of making gastric tube, breakthrough of anastomosis technique, and the presentation and application of new concepts, ERAS has made great progress in the field of esophagectomy. This article summarizes some ERAS measures in the treatment of esophageal cancer based on evidence-based medicine, and performs an effective ERAS mode for clinical application of esophagectomy. During preoperative preparation and evaluation, we propose preoperative education and nutrition evaluation without regular intestinal preparation, and advocate preemptive analgesia without preanesthetic medication. During intra-operative management, anesthesia scheme should be optimized, fluid transfusion should be controlled properly, suitable operation mode should be chosen, and intraoperative hypothermia should be avoided. During postoperative management, sufficient analgesia should be administered with non-opioid analgesics, drainage tube placement must be decreased and removed earlier, urinary catheter and gastrointestinal decompression tube should be removed earlier, and oral intake and ambulation should be resumed as early as possible. "Received surgery yesterday, oral intake today, discharged home 5-7 days", ERAS program based on "non tube no fasting" has been applied in some medical centers and becomes more and more maturation. In the future, we will rely on the increasing improvement and systemic training of ERAS mode in order to promote such application in more medical centers. With the multi-center clinical trials, based on constant enrichments and improvements, a general expert consensus will be made finally.

PURPOSE: We explored the performance of and pressure elevation caused by small-diameter microtubes used to reduce overfiltration. METHODS: Using a syringe pump-driven constant-flow setting (2 µL/min), pressures were measured for polytetrafluoroethylene (PTFE) microtubes 5 mm in length with inner diameters of 51, 64, and 76 µm and for polyether block amide (PEBAX) microtubes with an inner diameter of 76 µm. Experiments (using microtubes only) were initially performed in air, water, and enucleated pig eyes and were repeated under the same conditions using intraluminal 9/0 nylon stents. RESULTS: The pressures measured in air in 51-, 64-, and 76-µm-diameter PTFE microtubes differed significantly (22.1, 16.9, and 12.2 mmHg, respectively; p < 0.001), and that of the 76-µm-diameter PEBAX microtube was 15.8 mmHg (p < 0.001 compared to the 12.2 mmHg of the 76-µm-diameter PTFE microtube). The pressures measured in water also differed significantly among the three microtubes at 3.9, 3.0, and 1.4 mmHg, respectively, while that in the PEBAX microtube was 2.6 mmHg (all p < 0.001). Using the intraluminal stent, the pressure in water of the three different PTFE microtubes increased to 22.6, 18.0, and 4.1 mmHg, respectively, and that in the PEBAX microtube increased to 10.5 mmHg (all p < 0.001). Similar trends were evident when measurements were performed in pig eyes. CONCLUSIONS: Although microtubes of smaller diameter experienced higher pressure in air, reduction of the inner diameter to 51 µm did not adequately increase the pressure attained in water or pig eyes. Insertion of an intraluminal stent effectively elevated the latter pressures. PEBAX microtubes created higher pressures than did PTFE microtubes.

Since its initial introduction in 1976, percutaneous nephrolithotomy (PCNL) has been widely performed for the management of large renal stones and currently is recommended for staghorn calculi, kidney stones larger than 2 cm, and shock wave lithotripsy-resistant lower pole stones greater than 1 cm. However, except for open and laparoscopic surgery, PCNL is the most invasive of the minimally invasive stone surgery techniques. Over the years, technical and instrumental advances have been made in PCNL to reduce morbidity and improve effectiveness. A thorough review of the recent literature identified five major areas of progress for the advancement of PCNL: patient positioning, method of percutaneous access, development of lithotriptors, miniaturized access tracts, and postoperative nephrostomy tube management. This review provides an overview of recent advancements in PCNL and the outcomes of each area of progress and notes how much we achieve with less invasive PCNL. This information may allow us to consider the future role and future developments of PCNL.

OBJECTIVETo compare the advantages and disadvantages of the Foley catheter draining method versus the urethral stent plus gastric tube draining method for urine drainage following urethroplasty for hypospadias.

METHODSWe retrospectively analyzed the clinical data of 361 cases of hypospadias treated by urethroplasty. After operation, 91 of the cases received urine drainage with the Foley catheter (group A) and 270 with a urethral stent plus a gastric tube (group B). We compared the incidence rates of bladder irritation, fistula, urethral stricture, and urethral diverticulum between the two groups of patients.

RESULTSNo statistically significant differences were found between groups A and B in the incidences of bladder irritation (9.89% vs 10.70%, P > 0.05) and urethral diverticulum (1.09% vs 2.22%, P > 0.05). The incidence rate of fistula was markedly higher in group A than in B (20.80% vs 13.30%, P < 0.05), and so was that of urethral stricture (10.90% vs 5.55%, P < 0.05).

CONCLUSIONThe urethral stent plus gastric tube draining method is more effective than the Foley catheter draining method for urine drainage following urethroplasty.

OBJECTIVETo summarize the clinical effect of avulsed skin replantation of hand and foot via vacuum sealing drainage (VSD) combing low temperature technique.

METHODSFrom March 2012 to October 2013,13 cases with avulsed skin replantation of hand foot using combined technique included 8 males and 5 females with an average age of 32 years old ranging from 18 to 62 years. The time from injury to hospital was 1 to 4 hours (2.4 hour in average). The reasons of injury included machine injury in 7 cases and rolling over by cars in 6 cases. The parts of injuried involved finger in 2 cases,back of the hand in 5 cases and dorsum of foot in 6 cases. The area of avulsed skin was 5 cm x 6 cm to 12 cm x 16 cm,tendon and bone exposure was found in 4 cases. VSD was operated in all patients and the avulsed skin was refrigerated in the temperature of -4 °C or -80 °C. After 4 days, the skin stored in the -4 °C was replanted to the wounded place in 5 cases and in 3 cases the skin was planted to the donor site of flap. The skin stored in the -80 °C was replanted in 4 cases after 7 or 8 days, 1 case after 45 days.

RESULTSOf the 13 cases, 1 case of degloved injury from lower leg to dorsal foot,the replanted skin was necrosis completely; 1 case of degloving injury with fourth finger,the skin which replanted after 45 days survived approximately 30%,cured after skin-graft many times. In the other cases, the survival area of replanted skin was more than 85%, all cured after dressing. According to the standard of skin survival area evaluation by Jia et al, 11 cases showed excellent, 1 showed medium and 1 showed inferior. There were no complication about grafted skin rupture after the skin survived in 11 patients,after 4 to 22 months follow-up, the resiliency of grafted skin showed good. Sensation recovery was measured by BMRC standard: 3 cases of S3, 5 cases of S3, 3 cases of S2.

CONCLUSIONVSD combining lower temperature technique in skin replantation provides time and space for wound preparation and treatment plan for the patients who need second surgery, especially for the large area skin degloving,this method could utilize the degloved skin efficiently, decrease the donor site area, alleviate the pain and financial burden,reduce the scar formation of donor site and impediment.

Hilar cholangiocarcinoma has an extremely poor prognosis and is usually diagnosed at an advanced stage. Palliative management plays an important role in the treatment of patients with inoperable hilar cholangiocarcinoma. Surgical, percutaneous, and endoscopic biliary drainage are three modalities available to resolve obstructive jaundice. Plastic stents were widely used in the past; however, self-expanding metal stents (SEMS) have become popular recently due to their long patency and reduced risk of side branch obstruction, and SEMS are now the accepted treatment of choice for hilar cholangiocarcinoma. Bilateral drainage provides more normal and physiological biliary flow through the biliary ductal system than that of unilateral drainage. Unilateral drainage was preferred until recently because of its technical simplicity. But, with advancements in technology, bilateral drainage now achieves a high success rate and is the preferred treatment modality in many centers. However, the choice of unilateral or bilateral drainage is still controversial, and more studies are needed. This review focuses on the endoscopic method and discusses stent materials and types of procedures for patients with a hilar cholangiocarcinoma.
