Laparoscopic hernia repair remains controversial, and its position in current hernia surgery remains in flux. In this article we attempt to put the laparoscopic approach in perspective by describing the rationale for its development. We summarize studies comparing it with open repairs, including recent publications, meta-analyses, and systematic reviews; and we then contrast the data with recent findings of the United States Veterans Affairs Cooperative study 456. We discuss the current and future status of the laparoscopic approach to inguinal hernia repair and present an update of our own laparoscopic totally extraperitoneal technique without mesh fixation. From 1994 to 2004 we performed 314 hernia repairs on 224 patients with no intraoperative complications, no conversions to an open procedure, and no mortality. Thirty (14%) minor postoperative complications occurred. There were three herniated lipomas (preperitoneal fat) but no true peritoneal reherniations. We evaluate critical points of laparoscopic hernia repair including extensive preperitoneal dissection, mesh configuration, size and fixation, cost reduction, and the learning curve.

Although the PPV of abnormal HIDA EF is high, it is not much better than the clinical impression. The sensitivity and specificity are marginal. The NPV is poor. Based on the review of these 93 patients, HIDA EF is not reliable for identifying CAC. We recommend that patients with normal HIDA EF have additional testing or consultation before ruling out CAC. HIDA EF does not predict SOH.

Isolated microscopic haematuria is a common finding in the genitourinary clinic. The conventional approach to investigation includes urological referral for cystourethroscopy if renal imaging is normal. However the diagnostic yield is very low; in particular urothelial malignancy at age < 40 years is rare. Glomerular disease is increasingly recognized as a common cause of microscopic haematuria. In this study 50 patients with persistent microscopic haematuria detected at a genitourinary clinic underwent renal biopsy. Twelve (24%) had an abnormal biopsy--IgA nephropathy 6 (12%), thin membrane nephropathy 3 (6%), other glomerulonephritis 3 (6%). In 7 others no abnormality was found but information was incomplete as electron microscopy was unavailable. It is important to establish these diagnoses since some patients will develop progressive renal disease. In this clinical setting renal biopsy will give diagnostic and prognostic information, protects from repeated urological investigation, and allows reassurance if renal histology is normal. Renal biopsy is recommended for patients age < 40 years with persistent microscopic haematuria. An algorithm for the investigation of microscopic haematuria is presented.
