Urogenital neoplasms spreading to the inguinal lymph nodes are penile carcinoma (the most frequent), urethral and scrotum cancers, tumors of the testis with scrotal violation. Penile carcinoma is an uncommon malignant disease and accounts for as many 0.4-0.6% of male cancers. Most patients are elder...ly. It rarely occurs in men under age 60 and its incidence increases progressively until it reaches a peak in the eighth decade 1. The risk of a lymph node invasion is greater with high grade and high stage tumors 2. Some investigators have reported the inaccuracy of the sentinel node biopsy 3, 4, described by Cabanas 5. Patients with metastatic lymph node penis cancer have a very poor prognosis if penectomy only is performed. Ilioinguinal lymphadenectomy is basically carried out as a treatment modality and not only as a staging act. Patients with lymph node invasion have a 30-40% cure rate. Ilioinguinal lymphadenectomy should be also performed in patients with disseminated neoplasms for the local control of the disease. The 5 years survival rate of patients with clinically negative lymph nodes treated with a modified inguinal lymphadenectomy is 88% versus 38% in patients not initially treated with lymphadenectomy 6. This video-tape clearly shows a therapeutic algorithm, the anatomy of the inguinal lymph nodes, according to Rouviere 7 and Daseler 8, the radical ilioinguinal node dissection with transposition of the sartorius muscle and the modified inguinal lymphadenectomy proposed by Catalona 9.

Laparoscopy in acute bowel obstruction following previous surgery is a difficult procedure and avoided by most of the surgeons due to the difficulty in obtaining pneumoperitoneum, port placement, lack of working space, adhesions and risk of bowel injury.
Here is a patient who had a previous laparotomy for trauma with a midline incision from xyphysternum to pubis; after unsuccessful conservative management he underwent a laparoscopy; a prior CT scan showed adhesions in the left side and a distal-mid small bowel obstruction. The pneumoperitoneum was obtained with the Visiport placed in the right lower quadrant; although the abdomen was grossly distended, under significant tension and distended loops of small bowel were occupying most the peritoneal cavity, with muscle relaxation there is usually enough space to perform a thorough inspection of the abdominal cavity. Port placement has to be done with special care as there is no room to push and usually a blunt trocar directed away from the bowel is employed in my practice. The collapsed loops of small bowel point quickly to the site of obstruction -- it is better to avoid manipulating the distended bowel as it is heavy, oedematous and prone to be lacerated with the instruments; once the pathology is identified, in this case the obstructive band, light packing is performed in order to expose the working space and protect the bowel from instruments like scissors or diathermy. In this case the band adhesion was slightly more difficult to separate from the bowel and required a combination of sharp and gentle blunt dissection.
Once the obstruction is release and the transit of contents is confirmed in the collapsed bowel the procedure is terminated. No abdominal drainage is usually necessary.

The gold standard treatment for bladder outlet obstruction.This is an endoscopic procedure in which a resectoscope is placed transurethrally and the obstructing lobes of the prostate are removed as chips of tissue. TURP results in improvement of flow rate, and symptom scores are superior to that of other minimally invasive therapies
