Intra-abdominal laparoscopic pudendal canal decompression - a feasibility study.

Background: Pudendal canal syndrome (PCS) is induced by the compression or the stretching of the pudendal nerve within Alcock's canal.

Methods: Considering the difficulty and possible complications involved in exposing the pudendal canal and nerve by either transperineal, transgluteal or transischiorectal approaches, an intra-abdominal laparoscopic pudendal canal decompression (ILPCD) was employed. For this technique, 30 male adult human cadavers were examined.

The clinical anatomy of the posterior gastric artery revisited.

A consensus concerning the incidence, course and distribution of the posterior gastric artery (PGA) has yet to be reached. Recent literature has explored and subsequently demonstrated the importance of the identification of this vessel in surgical procedures such as subtotal gastrectomy, splenectomy and pancreatic transplantation. The gross anatomy of the PGA was examined in 120 adult human cadavers.

Multiple variations of the hepatobiliary vasculature including double cystic arteries, accessory left hepatic artery and hepatosplenic trunk: a case report.

Anatomical variations in the origins and branching patterns of the hepatobiliary arterial system may be encountered during both conventional surgical and laparoscopic cholecystectomy. We report a rare case of double cystic arteries arising from both the right hepatic artery and the proximal part of the posterior superior pancreaticoduodenal artery. Additional variations consisting of an accessory left hepatic artery arising from a left gastric which in turn arose from the descending aorta superior to the origin of the celiac trunk and a small left hepatic artery arising from the hepatic proper artery were also noted.

Benign anatomical mistakes: "ampulla of Vater" and "papilla of Vater".

The anatomy of the ampullary termination of the bile and pancreatic ducts is complex; appropriate terminology for this area is confusing and inaccurate. We examine the terms "ampulla of Vater" and "papilla of Vater" for anatomical and historical correctness. The term "ampulla" refers to a dilated part of a duct or other channel.

The history of anatomy and surgery of the preperitoneal space.

Preperitoneal (properitoneal) space is the space between the peritoneum and transversalis fascia. Bogros (1786-1825) described a triangular space in the iliac region between the iliac fascia, transversalis fascia, and parietal peritoneum. In the modern concept, this space lies between the peritoneum and posterior lamina of the transversalis fascia.

Absence of the left inferior thyroid artery: clinical implications.

Dissection of an adult male cadaver revealed an absence of the left inferior thyroid artery; its usual area of distribution to the thyroid gland was supplied by the right inferior thyroid artery. Absence of the left inferior thyroid artery occurs in 1-6% of cases. The inferior thyroid artery arises commonly from the thyrocervical trunk, passes posterior to the carotid sheath and supplies the inferior pole of the corresponding lobe of the thyroid gland; its branches can course anterior or posterior to or between branches of the recurrent laryngeal nerve.
