Percutaneous Retroperitoneoscopic Drainage of Complex Extraperitoneal Abscesses Using Flexible Endoscopy: Description of Technique and Perioperative Care.

The treatment of primary psoas abscesses usually is performed by a combination of prolongued antiobiotic therapy and drainage with interventional radiology techniques. However, although this combination is usually adequate for the treatment of solitary extraperitoneal collections, the presence of multi-loculated complex abscesses requires usually multiple procedures and feruently mandates open surgery. Herein, we describe an alternative tehnique of percutaneous retroperitoneoscopic drainage of multiple extensive primary psoas abscesses using flexible endoscopy, which can enable treatment these cases as one-stop proedure in a minimally invasive manner.

Visceral Pseudoaneurysm Embolisation Using 'Ping-Pong' Technique: Importance of Dual Arterial Catheterisation to Prevent Rupture.

Supracolic peri-pancreatic visceral pseudoaneurysms combine the challenges of difficult location for open surgical repair with unpredictable risk of fatal exsanguination. Endovascular embolisation is a well-established method of safely decompressing these lesions using a variety of thrombogenic agents. A single catheter technique is commonly employed to achieve this outcome.

Spontaneous, isolated caecal necrosis: report of a case, review of the literature, and updated classification.

Isolated necrosis of the caecum is a rare cause of abdominal pain. In the absence of occlusive vascular disease it has a number of well documented associations, the commonest of which is patients' receiving haemodialysis for endstage renal failure. It has also been associated with shock states, cardiac failure, ischaemic heart disease, diabetes and drugs such as cocaine, thiopentone and cytotoxic agents.

Verrucous carcinoma--an embarrassing problem?

Human papillomaviruses (HPVs) types 6 and 11 are usually associated with benign genital condylomata, but here we describe an extreme case of verrucous carcinoma associated with HPV 6 in a patient too embarrassed to seek early medical advice.

Rapid flow carbon dioxide laparoscopy disperses cancer cells into the peritoneal cavity but not the port sites in a new rat model.

Background: The role of carbon dioxide (CO2) in the pathogenesis of tumor recurrence after laparoscopy remains controversial. Using a new rat model, we studied the effect of different CO2 flow rates on the dispersal of free cancer cells.

Methods: A novel model of desufflation without trocar was developed, and 55 Fischer rats were randomized into three flow groups: group A (rapid, 0.
