RESUMO
Pediatric nasopharyngeal carcinoma is a rare malignancy strongly associated with Epstein-Barr virus infection. Patients typically present with non-specific symptoms of epistaxis or serous otitis from eustachian tube obstruction and therefore diagnosis is often delayed. We present a case of a previously healthy 17 year old female who initially complained of migraines which was resistant to oral medication. Symptoms progressed and she saw a dental surgeon for concern of a dental infection and was prescribed antibiotics with no relief. Her symptoms continued to progress until an otolaryngologist visualized a large mass along the floor of the left nasal cavity. Subsequent imaging showed a large mass in the posterior left nasal cavity and biopsy was consistent with nasopharyngeal carcinoma.
RESUMO
PURPOSE: While laparoscopic donor nephrectomy has encouraged living kidney donation, debate exists about the safest laparoscopic technique. We compared purely laparoscopic and hand assisted laparoscopic donor nephrectomies in terms of donor outcome, early graft function and long-term graft outcome. MATERIALS AND METHODS: We reviewed the records of consecutive laparoscopic and hand assisted laparoscopic donor nephrectomies performed by a single surgeon from 2002 to 2011. Donor operative time and perioperative morbidity were compared. Early graft function for kidneys procured by each technique was evaluated by rates of delayed graft function, need for dialysis and recipient discharge creatinine. Long-term outcomes were evaluated by graft function. RESULTS: A total of 152 laparoscopic donor nephrectomies were compared with 116 hand assisted laparoscopic donor nephrectomies. Hand assisted procedures were more often done for the right kidney (41.1% vs 17.1%, p <0.001) and in older donors (age 41.4 vs 37.5 years, p = 0.011). Warm ischemia time was shorter for hand assisted than for purely laparoscopic nephrectomy (120 seconds, IQR 50 vs 145, IQR 64, p <0.001). Median operative time was slightly shorter for the hand assisted than for the purely laparoscopic procedure (155 vs 165 minutes, p = 0.038). In each group 2 intraoperative complications required intervention (open conversion in 1 case each). Postoperatively complications developed after 5 purely laparoscopic and 5 hand assisted operations (1 Clavien 3b in each). Median length of stay was 2 days for each surgery. Postoperatively recipient outcomes were also similar. Delayed function occurred after 0% hand assisted vs 0.9% purely laparoscopic nephrectomies, dialysis was required in 0.9% vs 1.7% and rejection episodes developed in 9.7% vs 18.4% (p >0.05). At last followup the organ was nonfunctioning in 6.1% of hand assisted and 7.7% of purely laparoscopic cases (p >0.05). The recipient glomerular filtration rate at discharge home was similar in the 2 groups. CONCLUSIONS: Hand assisted laparoscopic donor nephrectomy had shorter warm ischemia time but perioperative donor morbidity and graft outcome were comparable. The choice of technique should be based on patient and surgeon preference.

PURPOSE: Open surgery after cystectomy can be a challenge. We report the incidence of postoperative urinary diversion-enteric fistula and ureteral strictures in patients undergoing radical cystectomy, and discuss the diagnosis and management of these complications, including our surgical approach to these patients. MATERIALS AND METHODS: We preformed a retrospective review of 553 patients undergoing radical cystectomy and urinary diversion for bladder cancer between April 1999 and January 2007. Patients in whom a ureteral stricture or fistula developed were identified by serial laboratory and imaging evaluations. A chart review was preformed to identify symptoms, time to stricture or fistula development, radiological findings, type of diversion, estimated blood loss and whether the original anastomosis was stented. Management and outcomes were assessed. RESULTS: Of 553 patients reviewed ureteral stricture developed in 41 (7.4%) with a mean followup of 20.2 months (range 1 to 98). Strictures developed in 11% (31 of 272) of the orthotopic ileal neobladder, 2.5% (6 of 236) of ileal conduit and 8% (4 of 45) of Indiana pouch cases. Open repair led to an overall success rate of 87%. Urinary diversion-enteric fistula developed in 12 (2.2%) of the 553 patients with a mean followup of 28.4 months (range 3 to 94), all of whom had undergone orthotopic neobladder diversion. No patient had recurrence after surgical repair of the fistula. CONCLUSIONS: Open revision remains the gold standard management for ureteral strictures and urinary diversion-enteric fistulas occurring after radical cystectomy. The addition of the chimney modification to the orthotopic neobladder facilitates surgical repair.
