PURPOSE: Inguinal herniorrhaphy is the most common general surgical procedure. It is associated with frequent complications such as recurrence (1.9% with mesh), post-operative hematoma (4.5%), reduced sensation (0 - 42.8%), chronic post-operative pain (5.1%), vasal injury (0.1 - 0.53%) and infection (3 - 6%)1-5. Drawing on our experience utilizing the operating microscope for varicocelectomy, vasectomy reversal and repair of iatrogenic vasal obstruction from hernia repair, we employed it for inguinal hernia repair. This paper describes the rationale, technique and outcomes of microsurgically assisted inguinal hernia repair. MATERIALS AND METHODS: 291 microsurgically assisted inguinal hernia repairs were performed on 253 men by the same urologist (MG). Simultaneous microsurgical varicocelectomy or other testicular procedures were performed in 83% of cases. All were open repairs through an inguinal incision with the vas deferens, ilioinguinal nerve, genital branch of the genitofemoral nerve and spermatic vasculature identified and preserved. Median follow up was 8.6 months, and outcomes were assessed through examination, pain reporting and pathology reports. RESULTS: Chronic postoperative pain, sensory loss, infection, hematoma, vasal injury and recurrence were assessed. The incidence of hematoma was 0.85%. No hernia recurrences, chronic postoperative pain, sensory loss, infection or vasal injury was reported. CONCLUSIONS: Using an operating microscope, complications of inguinal hernia repair such as vasal obstruction, testicular atrophy, recurrence, infection, hematoma, chronic postoperative pain and loss of sensation are minimized. Microsurgically assisted hernia repair is a promising technique, especially when employed by a urologist performing simultaneous microsurgical varicocelectomy or procedures involving spermatic cord structures or testis.

OBJECTIVE: Examine oral complications 6 months after modern radiation therapy (RT) for head and neck cancer (HNC). METHODS: Prospective multi-center cohort study of HNC patients receiving Intensity-Modulated Radiation Therapy (IMRT) or more advanced RT. Stimulated whole salivary flow, maximal mouth opening, oral mucositis, oral pain, oral health-related quality of life (OH-QOL), and oral hygiene practices, were measured in 372 subjects pre-RT and 216 at 6 months from start of RT. RESULTS: Mean stimulated whole salivary flow declined from 1.09 ml/min to 0.47 ml/min at 6 months (p < 0.0001). Mean maximal mouth opening reduced from 45.58 mm to 42.53 mm at 6 months (p < 0.0001). 8.1% of subjects had some oral mucositis at 6 months, including 3.8% with oral ulceration. Mean overall pain score was unchanged. OH-QOL was reduced at 6 months, with changes related to dry mouth, sticky saliva, swallowing solid foods, and sense of taste (p
