The improvements in the duration of surgery and visual outcome noted after about 50 endoscopic procedures would favor the existence of an operative learning curve for these parameters. This further highlights the benefits of subspecialization in pituitary surgery.

Colorectal cancer in Egypt has no age predilection and more than one-third of tumors affects a young population. The high prevalence in young people can neither be explained on a hereditary basis nor can it be attributed to bilharziasis. The disease usually presents at an advanced stage, and predisposing adenomas are rare. Similarity of the data from different centers suggests that this is the picture of colorectal cancer typical of Egypt.

The double urethra is a diverse spectrum comprising different pathologies. Our proposed classification system of duplicated urethras is clinically relevant as it guides surgical management and allows prognostication of outcome.

The characteristics of large bowel cancer in young Egyptian patients do not differ significantly from those in older patients. Despite the high incidence of large bowel cancer in young Egyptian patients, family history and pathologic features of tumors do not support a hereditary origin of colorectal cancer in this age group in Egypt.

Abstract:Objective: The objective of this study was to describe a modification for skin closure combined with tubularized incised plate (TIP) urethroplasty in the repair of proximal and mid-penile hypospadias. Patients and methods:The study included 47 patients with nondistal hypospadias who underwent a primary TIP procedure from September 2007 to May 2010. Meatal position was mid-shaft (n = 20), penoscrotal (n = 20), and scrotal (n = 7). The patients in the study were divided into two groups according to a modification in the technique of skin closure, which involved incising the prepuce vertically into two halves, then harvesting the dartos flap for covering the repair from one half, leaving the other preputial half to reconstruct the ventral skin without compromising its blood supply. Results: In the standard procedure (n = 19 patients), complications included glanular dehiscence (10.5%), glanular fistula (5%), urethrocutaneous fistula (10.5%), and skin complications (21%). In the modified procedure (n = 28 patients), complications included glanular dehiscence (7%) and glanular fistula (3.6%), but no skin complications or urethrocutaneous fistulae occurred. Conclusion:The modified Byars' flaps is a useful alternative for skin closure during proximal and mid-shaft TIP urethroplasty, with fewer complications and acceptable cosmetic outcome.
