Indwelling catheter and conservative measures in the treatment of abdominal compartment syndrome in fulminant acute pancreatitis

AIM： To study the effect of combined indwelling catheter, hemofiltration, respiration support and traditional Chinese medicine （e.g. Dahuang） in treating abdominal compartment syndrome of fulminant acute pancreatitis. METHODS： Patients with fulminant acute pancreatitis were divided randomly into 2 groups of combined indwelling catheter celiac drainage and intra-abdominal pressure monitoring and routine conservative measures group （group 1） and control group （group 2）. Routine non-operative conservative treatments including hemofiltration, respiration support, gastrointestinal TCM ablution were also applied in control group patients. Effectiveness of the two groups was observed, and APACHE Ⅱ scores were applied for analysis. RESULTS： On the second and fifth days after treatment, APACHE Ⅱ scores of group 1 and 2 patients were significantly different. Comparison of effectiveness （abdominalgia and burbulence relief time, hospitalization time） between groups 1 and 2 showed significant difference, as well as incidence rates of cysts formation. Mortality rates of groups 1 and 2 were 10.0% and 20.7%, respectively. For patients in group 1, celiac drainage quantity and intra-abdominal pressure, and hospitalization time were positively correlated （r = 0.552, 0.748, 0.923, P 〈 0.01） with APACHE Ⅱ scores. CONCLUSION： Combined indwelling catheter celiac drainage and intra-abdominal pressure monitoring, short veno-venous hemofiltration （SVVH）, gastrointestinal TCM ablution, respiration support have preventive and treatment effects on abdominal compartment syndrome of fulminant acute pancreatitis.

Management of recurrent malignant pleural effusions with a tunneled indwelling pleural catheter

In this review, we report on the use of indwelling pleural catheters in the treatment of malignant pleural effusions. We describe the most commonly used catheter. Also, treatment with indwelling pleuralcatheters as compared to talc pleurodesis is reviewed. A comparison of efficacy, costs, effects on quality of life, and complications is made. Only one randomized controlled trial comparing the two is available up to date, but several are underway. We conclude that treatment for malignant pleural effusions with indwelling pleural catheters is a save, cost-effective, and patientfriendly method, with low complication rates.

New cannulation method for pancreatic duct cannulationbile duct guidewire-indwelling method

The patient was a 58-year-old male with symptomatic alcoholic chronic pancreatitis.Since a 10 mm calculus was observed in the pancreatic body and abdominal pain occurred due to congestion of pancreatic juice,endoscopic retrograde cholangiopancreatography was conducted for assessment of the pancreatic duct and treatment of pancreatic calculus.Pancreatogram was slightly and insuff iciently obtained by injecting the contrast media via the common channel of the duodenal main papilla.We tried to cannulate selectively into the pancreatic duct for a clear image.However,the selective cannulation of the pancreatic duct was difficult because of instability of the papilla.On the other hand,selective cannulation of the bile duct was relatively easily achieved.Therefore,after the imaging of the bile duct,a guidewire was retained in the bile duct to immobilize the duodenal papilla and cannulation of the pancreatic duct was attempted.As a result,selective pancreatic duct cannulation became possible.It is considered that the bile duct guidewire-indwelling method may serve as one of the useful techniques for cases whose selective pancreatic duct cannulation is diff icult("selective pancreatic duct diff icult cannulation case").

Application of Modified Gastric Tube Placement in Patients with Indwelling Gastric Tube

Objective:To explore the effect of modified nasogastric tube placement and Rehabilitation New Liquid Spray in patients with indwelling gastric tube.Methods:Eighty-six cases with indwelling gastric tube in our hospital from January 2020 to May 2021 were randomly selected and divided into the reference group and the research group.The reference group was treated by modified gastric tube placement,and the research group was given the Rehabilitation New Liquid Spray intervention.The effect of the interventions on two groups was observed.Results:The incidence of nasal mucosal injury in the research group was lower than that in the reference group,and the incidence of pharyngeal mucosal injury in the research group was lower than that in the reference group(P<0.05).The pain score of the study group was lower than that of the reference group at 8 h,12 h and 24 h after replacement,and the incidence of hoarseness,swallowing discomfort and dry oropharynx was lower than that of the reference group(P<0.05).Conclusion:The application of modified gastric tube placement and Rehabilitation New Liquid Spray intervention in patients with indwelling gastric tube can effectively reduce the nasopharyngeal injury and improve the pain of catheterization.

Development and validation of a risk prediction model for repeated indwelling urinary catheterization in patients with cervical cancer after surgery

Objective:To study the factors influencing secondary indwelling catheterisation after cervical cancer surgery and to develop a predictive risk model.Methods:A total of 260 patients in a tertiary hospital in Chongqing were selected from January 2020 to December 2021 via convenience sampling.Relevant information of patients was recorded,including age;body mass index;history of hypertension and diabetes,bladder dysfunction,postoperative urinary retention,and postoperative urinary tract infection;Histology;staging;surgical approach;Operation time;Time of first remove of catheter;indwelling catheter days;Hospitalization days.Least absolute shrinkage and selection operator was used to reduce dimensionality and select patient characteristics,and multivariate analysis was performed based on the selected variables.Based on the outcome of analysis,a line chart model was developed for predicting the risk of secondary catheterization in patients with indwelling catheterization after radical cervical cancer surgery.The coefficient of conformity index(C-index)and calibration curves were used to evaluate the accuracy and fit.The model was internally validated via bootstrapping(1000 random samples),and the clinical utility of the model was assessed via decision curve analysis(DCA).Results:Four characteristic variables were selected,including preoperative bladder function,postoperative urinary tract infection,surgical approach,and Time of first remove of catheter.They are independent risk factors affecting urinary tract.The risk prediction model exhibited good discrimination performance with a C-index of 0.722(95%CI,0.661-0.783)and was well calibrated.The C-index was 0.708 in internal validation analysis.DCA showed that the risk model was clinically useful for predicting secondary catheterization,and clinical benefits were observed at the decision threshold of≥11%.Conclusion:A novel model was developed to predict the risk of secondary catheterization.The model was based on preoperative bladder dysfunction,postoperative urinary tract infection,surgical approach,and number of days since the removal of the primary catheter.

Indwelling Pleural Catheter Insertion Following Inefficient Thoracoscopic Decortication in Postpneumonic Empyema: Beneficial or Contraindicated?

Video assisted thoracic surgery in advanced stage postpneumonic empyema aims for thorough debridement and washout of the pleural space followed by an attempt to release the entrapped lung (decortication). When the latter isn’t successful, and the patient is in a poor performance status, applying tube thoracostomy is the usual routine, to avoid conversion to thoracotomy and open decortication. Tube thoracostomy, however, is associated with complications necessitating further surgery, needs long term follow up and also entails quality of life distorting issues. To overcome these disadvantages, we instead inserted a PleurX&reg indwelling pleural catheter in four patients in the above situation. The method brought success (lung re-expansion and complete or partial pleurodesis) without the need for further surgery or quality of life problems in either patient. Although the use of the indwelling pleural catheter in infected pleural space is not recommended by manufacturers, we noted no complications.

T-tube vs no T-tube for biliary tract reconstruction in adult orthotopic liver transplantation:An updated systematic review and metaanalysis

BACKGROUND Whether to use a T-tube for biliary anastomosis during orthotopic liver transplantation(OLT)remains a debatable question.Some surgeons chose to use a T-tube because they believed that it reduces the incidence of biliary strictures.Advances in surgical techniques during the last decades have significantly decreased the overall incidence of postoperative biliary complications.Whether using a T-tube during OLT is still associated with the reduced incidence of biliary strictures needs to be re-evaluated.AIM To provide an updated systematic review and meta-analysis on using a T-tube during adult OLT.METHODS In the electronic databases MEDLINE,PubMed,Scopus,ClinicalTrials.gov,the Cochrane Library,the Cochrane Hepato-Biliary Group Controlled Trails Register,and the Cochrane Central Register of Controlled Trials,we identified 17 studies(eight randomized controlled trials and nine comparative studies)from January 1995 to October 2020.The data of the studies before and after 2010 were separately extracted.We chose the overall biliary complications,bile leaks or fistulas,biliary strictures(anastomotic or non-anastomotic),and cholangitis as outcomes.Odds ratios(ORs)with 95%confidence intervals(CIs)were calculated to describe the results of the outcomes.Furthermore,the test for overall effect(Z)was used to test the difference between OR and 1,where P≤0.05 indicated a significant difference between OR value and 1.RESULTS A total of 1053 subjects before 2010 and 1346 subjects after 2010 were included in this meta-analysis.The pooled results showed that using a T-tube reduced the incidence of postoperative biliary strictures in studies before 2010(P=0.012,OR=0.62,95%CI:0.42-0.90),while the same benefit was not seen in studies after 2010(P=0.60,OR=0.76,95%CI:0.27-2.12).No significant difference in the incidence of overall biliary complications(P=0.37,OR=1.41,95%CI:0.66-2.98),bile leaks(P=0.89,OR=1.04,95%CI:0.63-1.70),and cholangitis(P=0.27,OR=2.00,95%CI:0.59-6.84)was observed between using and not using a T-tube before 2010.However,using a T-tube appeared to increase the incidence of overall biliary complications(P=0.049,OR=1.49,95%CI:1.00-2.22),bile leaks(P=0.048,OR=1.91,95%CI:1.01-3.64),and cholangitis(P=0.02,OR=7.21,95%CI:1.37-38.00)after 2010.A random-effects model was used in biliary strictures(after 2010),overall biliary complications(before 2010),and cholangitis(before 2010)due to their heterogeneity(I2=62.3%,85.4%,and 53.6%,respectively).In the sensitivity analysis(only RCTs included),bile leak(P=0.66)lost the significance after 2010 and a random-effects model was used in overall biliary complications(before 2010),cholangitis(before 2010),bile leaks(after 2010),and biliary strictures(after 2010)because of their heterogeneity(I2=92.2%,65.6%,50.9%,and 80.3%,respectively).CONCLUSION In conclusion,the evidence gathered in our updated meta-analysis showed that the studies published in the last decade did not provide enough evidence to support the routine use of T-tube in adults during OLT.

Pediatric T-tube in adult liver transplantation:Technical refinements of insertion and removal

BACKGROUND With the increasing use of extended-criteria donor organs,the interest around Ttubes in liver transplantation(LT)was restored whilst concerns regarding T-tuberelated complications persist.AIM To describe insertion and removal protocols implemented at our institution to safely use pediatric rubber 5-French T-tubes and subsequent outcomes in a consecutive series of adult patients.METHODS Data of consecutive adult LT patients from brain-dead donors,treated from March 2017 to December 2019,were collected(i.e.,biliary complications,adverse events,treatment after T-Tube removal).Patients with upfront hepaticojejunostomy,endoscopically removed T-tubes,those who died or received retransplantation before T-tube removal were excluded.RESULTS Seventy-two patients were included in this study;T-tubes were removed 158 d(median;IQR 128-206 d)after LT.In four(5.6%)patients accidental T-tube removal occurred requiring monitoring only;in 68(94.4%)patients Nelaton drain insertion was performed according to our protocol,resulting in 18(25%)patients with a biliary output,subsequently removed after 2 d(median;IQR 1-4 d).Three(4%)patients required endoscopic retrograde cholangiopancreatography(ERCP)due to persistent Nelaton drain output.Three(4%)patients developed suspected biliary peritonitis,requiring ERCP with sphincterotomy and nasobiliary drain insertion(only one revealing contrast extravasation);no patient required percutaneous drainage or emergency surgery.CONCLUSION The use of pediatric rubber 5-French T-tubes in LT proved safe in our series after insertion and removal procedure refinements.

Results of Montgomery T-Tube in Primary Treatment of Laryngotracheal Stenosis

Introduction: For tracheal stenosis, tracheal resection and anastomosis is widely considered the treatment of choice. However, this surgical approach is not feasible when the glottis and subglottis are involved or in patients with a poor general condition and tracheal stents are a plausible means of providing a permanent or temporary airway opening. Objectives: Evaluate the features and the results of patients with Montgomery T-tube in tracheal stenosis. Methods: Fifteen patients with Myer-Cotton grades 2-3 circular cicatricial tracheal stenosis who received a Montgomery T-tube between 2002-2011 were analyzed in terms of age, gender, etiology, duration of intubation, location and size of the stenotic segment on computed tomography(CT), follow-up time with the T-tube, the complications that occurred after T-tube removed and additional tracheal surgery. Conclusion: A T-tube can be applied in tracheal stenosis at the first treatment before attempting surgery. The patients should be closely followed-up due to the possibility of re-stenosis and other complications.
