Objective: Our objective was to determine the rate of complications in endoscopic sinus surgery (ESS) and associated risk factors.
Methods: We prospectively studied 1,382 subjects undergoing ESS for rhinosinusitis and cystic sinus disease at 16 hospitals during 2007 and 2008. Surgeons provided information on peri-and postoperative complication occurrence.
Result: Results of complications were seen in 80 subjects (5.8%), the most frequent was perioperative lamina papyracea injury. Analysis showed the complication rate to be linked to gender, and anesthesia type, but not the grade of surgeon.
Conclusions: While care should be taken to avoid them, complications should be identified and treated in a timely and accurate manner.

Many reports suggest tonsillectomy efficacy in subjects with early-stage IgA nephropathy (IgAN). Post-renal-transplant treatment in recurrent IgAN must, however, be assessed carefully. Recent reports show that tonsillectomy to also be effective in such recurrent cases. We studied 13 subjects with recurrence diagnosed histopathologically in allogenic kidney transplantation involving tonsillectomy from March 2008 to March 2010. Tonsillectomy was done on average of 74 months (15-180 months) after transplantation. Subjects averaged 44.8 years of age (29-67 years old). Buried tonsil was most common and 12 of 13 involved pus. One subject suffered slight bleeding 1 week after tonsillectomy, manageable conservatively. Steroid pulse therapy was added in 1 case after tonsillectomy due to histopathological renal biopsy suggesting severe renal injury. In most cases, serum creatinine (SCr) and urinary findings improved after tonsillectomy, which is thus expected to be effective in subjects with recurrent early-stage IgAN following renal transplantation, not only in those with IgAN.
