Objective:
Laparoscopic ureteral surgery is becoming increasingly common; however, advanced laparoscopic skills are required due to the precise suturing involved. Because of the size of the ureter and need for careful mucosal apposition to prevent stricturing, there is less room for error than with larger lumens, as in pyeloplasty. We sought to identify whether the presence of a stent is beneficial or a hindrance in performing ureteroureterostomy both for the novice and more experienced laparoscopist.Materials and Methods:
Eight ureteroureteral anastomoses were performed on each ureter of a 50 kg female pig for a total of 16 anastomoses. Eight were performed with a stent in place, and 8 were performed without a stent. An equal number with and without a stent were performed by a novice and an experienced laparoscopist. Anastomoses were graded by time to complete and quality of the anastomosis. Quality was graded by the presence and size of defects and patency of the lumen.Results:
The overall times required for ureteral division and spatulation, initial stitch placement, completion of the anastomosis, and total time for the stented vs. nonstented procedures were 4.3 vs. 2.2 minutes (P=0.05), 4.2 vs. 4.4 minutes (P=0.16), 10.4 vs. 13.5 (P=0.22) minutes, and 18.3 vs. 20.1 minutes (P=0.49), respectively. For stented and nonstented ureters, 3 vs. 5 anastomoses were found to have no or very small gaps, 5 vs. 1 anastomosis were found to have large gaps, and 0 vs. 2 anastomoses were found to have occluded lumens, respectively.Conclusions:
For both the novice and experienced surgeon, presence of a stent did not affect the overall time to complete a ureteroureteral anastomosis despite the significantly longer time needed to divide and spatulate the ureter. There were no occlusions when the ureteral stent was placed prior to suturing, which may indicate a reduced risk of “back-walling” the ureter. 相似文献14.

Background
Tracheoesophageal fistula (TEF) is the most common congenital tracheal abnormality, frequently associated with esophageal atresia. Respiratory symptoms are associated with all types of TEF, even after surgical repair of the fistula. Gastroesophageal reflux (GER) with aspiration of gastric contents, structural instability of the airways (tracheomalacia), abnormal respiratory epithelium, abnormal esophageal motility, recurrent TEF, and esophageal stenosis contribute to postsurgical complications.Methods
We review 7 patients between 4 and 14 years of age with a history of TEF repair and persistent or worsening respiratory symptoms despite conventional airway clearance techniques and treatment of GER.Results
Bronchoscopic evaluation in all 7 patients revealed tracheomalacia and a diverticulum on the posterior wall of the trachea at the fistula repair site.Conclusion
We hypothesize that the diverticula impaired airway clearance and contributed to persistent respiratory symptoms. Possible mechanisms for the diverticulum contributing to poor airway clearance include facilitating the pooling of secretions and acting as a “barrier” to the lower airway clearance mechanism. The diagnosis of a diverticulum should be considered early in patients with persistent respiratory symptoms after management of GER and tracheomalacia. Early obliteration of tracheal diverticula might improve respiratory status in some patients. 相似文献19.
