[Risk factors affecting the surgical outcome of severe tracheal stenosis]

Objective:To investigate the risk factors affecting the surgical outcome of severe tracheal stenosis. Methods:The data of 36 patients with severe tracheal stenosis were analyzed retrospectively. All patients underwent tracheal stenosis resection with primary end-to-end anastomosis.Six factors including the location of tracheal stenosis, the length of resected trachea, the degree of stenosis, scar constitution, diabetes and gastroesophageal reflux disease were analyzed by univariate analysis and multivariate Logistic regression analysis. Results:Finally, 23 cases were extubated,including 19 cases with successful extubation and 4 cases with granulation tissue removed by bracing laryngoscope.Univariate analysis showed that the location of tracheal stenosis, the length of resected trachea,scar constitution, diabetes and gastroesophageal reflux disease were the risk factors affecting the surgical efficacy of severe tracheal stenosis.The multivariate Logistic regression coefficients of each factor were 2.857, 1.761, 3.123, -1.066, 3.545 respectively. Conclution: The risk factors affecting the outcome of severe tracheal decannulation rate were the location of tracheal stenosis, the length of resected trachea, scar constitution, diabetes and gastroesophageal reflux disease. Among them, the stenosis position, the length of the resected trachea, scar constitution and gastroesophageal reflux disease had more significant effects on the prognosis of the operation, and the comprehensive evaluation of these risk factors before operation was conducive to improve the surgical effect.

[Efficacy analysis of T type tube dilatation in adult cervical tracheal stenosis]

Objective:To investigate the efficacy, recurrence and strategy of T silicone tube dilatation for cicatricial stenosis of cervical trachea in adults.Method:Cinical data of 37 cases with the cervical tracheal stenosis were retrospectively analyzed, who were firstly treated by T shape silicone tube dilation for at least 10 months, from Jun 2006 to Jun 2016.Result:In 37 adult patients with cicatricial stenosis of the trachea, 29 cases were caused by tracheal intubation or incision, 6 cases were traumatic, and 2 cases were multiple osteochondritis. Twentythree cases were experienced one time surgery and extubated successfully, 8 cases were experienced 2 times and more than 2 times surgery (sternohyoid muscle flap pedicled hyoid bone with T tube expansion in 3 cases, tracheal endoscopic dilatation in 2 cases, T tube dilatation in 3 cases), extubation success rate of 83.7%. Among the 6 cases with failure of extubation, 2 cases were multiple osteochondritis, 3 cases had severe scar constitution, 1 cases were lost of follow-up.Conclusion:T type silicon tube expansion for the treatment of adult cervical tracheal stenosis can be achieved relatively high decannulation rate. For recurrent stenosis, we can consider to use various methods of expansion, and improve the decannulation rate. Intratracheal granulation tissuextubation after exbation should be observed for at least 1 month. For concurrent with polychondritis and severe scar the constitution, the operation should be carefully chosen.

Appropriate Patient Selection Is Essential for the Success of Primary Closure After Laparoscopic Common Bile Duct Exploration

BACKGROUND

Laparoscopic common bile duct exploration (LCBDE) is being increasingly used for management of common bile duct (CBD) stones. Primary CBD closure has been reported to have better short-term outcomes compared to T-tube placement. However, primary CBD closure cannot be performed in all patients.

AIM

This study aims to evaluate the short- and long-term outcomes of LCBDE with primary CBD closure in appropriately selected patients and compare them with T-tube drainage.

METHODS

Retrospective analysis of patients undergoing LCBDE in our department from June 2011 to October 2014 was performed. Primary closure was performed in 52 patients (group A), and a T-tube was placed in 33 patients (group B). Patient demographics, intraoperative findings, postoperative stay, complications, and long-term follow-up data were recorded and compared.

RESULTS

The mean operating time was much longer in group A compared to group B (113.92 vs. 95.92 min, p = 0.032). The overall complication rate (9.6 vs. 6.3%, p = 0.701) and hospital stay (4 vs. 5.11 days, p = 0.088) were similar in both groups. No patient required conversion to the open procedure. Bile leakage was more frequent in group A (5.78 vs. 0%, p = 0.279), but this was not statistically significant. All three patients with bile leakage were treated successfully by conservative measures and gradual drain withdrawal. On long-term follow-up, recurrent stones were detected in two patients in group A. No patient was found to develop CBD stricture.

CONCLUSION

LCBDE and primary CBD closure has excellent short- and long-term outcomes when performed in appropriately selected patients.

Design and clinical application of a double lumen T tube

AIM: To design a double lumen T tube, investigate its hydrodynamic characteristics, and assess its clinical application.

METHODS: A retrospective study was carried out to analyze the data of patients who underwent biliary tract operations with placement of a double lumen T tube from March 1989 to March 2015 at the Department of Hepatobiliary Surgery of Binzhou Medical University Hospital. This study introduced the design, placement and operational method of the double lumen T tube, investigated its hydrodynamic characteristics, analyzed the complications, and assessed its clinical application in biliary tract irrigation, bile culture, cholangiography and enteral nutrition.

RESULTS: Based on the function of double lumen T tube, it was divided into two types: Ⅰ (for biliary irrigation) and type Ⅱ (for enteral nutrition). For type Ⅰ double lumen T tube, the short arm was placed in the extrahepatic bile duct, and the long arm was brought out through the abdominal wall; the inner tube was placed in left or right secondary or tertiary intrahepatic bile duct, with the end outside the body connected to saline for flushing. For type Ⅱ double lumen T tube, the short arm was placed in the extrahepatic bile duct, and the long arm was brought out through the abdominal wall; the inner tube was placed into the duodenum or jejunum through the duodenal papilla or anastomotic stoma, with the end outside the body connected to nutrition solution for enteral nutrition. A total of 1020 patients underwent placement of the double lumen T tube, including 660 who used type Ⅰ and 360 who used type Ⅱ tube. T tube placement time was 5-92 d, with an average value of 23.5 d. Complications included T tube dislocation (2 cases, 0.20%), lumen blockage (12 cases, 1.18%), infection around T tube (23 cases, 2.26%), hemobilia (2 cases, 0.2%), difficulty in removing (1 case, 0.10%), biliary fistula (11 cases, 1.08%), and peritonitis after T tube removal (2 cases, 0.20%). Moreover, 665 cases underwent biliary tract irrigation, and bile culture was performed in 343 cases; the positive rate of bacteria culture was lower than that observed in patients using conventional T tube. In 657 cases who underwent cholangiography, the rate of satisfaction was 98.2%. 358 cases accepted enteral nutrition with type Ⅱ double lumen T tube, and 314 cases underwent simultaneous bile external drainage and pancreatic juice reinfusion.

CONCLUSION: The double lumen T tube is easily made and convenient to use with lower complications. It can be safely used for biliary flushing, bile culture, cholangiography and enteral nutrition after biliary tract operations.

The difficult hepaticojejunostomy after pancreatic head resection: reconstruction with a T tube

BACKGROUND

After pancreatic head resection, bile leaks from a difficult hepaticojejunostomy secondary to a small or fragile common hepatic duct may be reduced by a T tube at the side of the anastomosis.

METHODS

A retrospective analysis of patients who underwent a difficult hepaticojejunostomy without or with a T tube was performed.

RESULTS

In 48% (55/114) of patients, a T tube was placed at the side of the hepaticojejunostomy; 52% (59/114) did not have a T tube. Bile leaks occurred in 12% (14/114) (9% [5/55] in patients with a T tube vs 15% [9/59] without a T tube, P = .316). Bile leaks were associated with mortality, abscess formation, hemorrhage, and sepsis. Seven percent (8/114) of patients required revisional laparotomy (2% [1/55] with a T tube vs 12% [7/59] without a T tube, P = .036). Mortality was not different between the groups. Minor T-tube-associated complications occurred in 15% (8/55) without major complications.

CONCLUSIONS

Augmentation of anastomosis with a T tube cannot prevent biliary leakage but does reduce the severity of bile leaks, resulting in less reoperations.

Closure of the Common Duct -Endonasobiliary Drainage Tubes vs. T Tube: A Comparative Study

For the last century T tube drainage of the bile duct has remained standard practice following choledochlithotomy. It vents the biliary tree, provides route for cholangiography and management of residual stones. However, T tubes are associated with significant complications. This retrospective study compared the use of Endonasobiliary drainage tubes and the T tube in 66 patients who underwent open choledocholithotomy for effectiveness and complications. Both groups were statistically comparable. Only 15.15% patients in the Endonasobiliary drainage group, while 45.45% patients in the T tube group developed complications. Severe complications such as biliary peritonitis and intraperitoneal collections were noted only in the T tube group. The Endonasobiliary drainage tube was removed significantly earlier and patients from this group were discharged earlier as compared to those in the T tube. The Endonasobiliary drainage tube is as effective as the T tube in postoperative biliary drainage and allows cholangiograms to be performed. Its use is associated with less complications and it can be removed safely earlier than the T tube. Thus patients have a shorter time with tubes and can be discharged home earlier.

Spontaneous common bile duct perforation presenting as acute abdomen

Spontaneous common bile duct (CBD) perforation is an unusual cause of acute abdomen. It is rarely suspected or correctly diagnosed preoperatively. Clinical presentation is as biliary peritonitis. The common causes are CBD calculus disease, tumors of the bile duct, choledochal cyst and sometimes idiopathic. Treatment is surgical and consists of CBD exploration and repair over a T tube.
