BACKGROUND: Splenic flexure mobilization (SFM) is sometimes required for secure and tension-free anastomosis during laparoscopic colorectal surgery. Although several approaches have been used for laparoscopic SFM,1 it is still considered complicated and troublesome because of the lack of a standardized technique. We propose a three-step method for laparoscopic SFM, aimed at providing a simplified and standardized method, which is presented in the video. METHOD: First, the mesocolon of the transverse and descending colon is dissected from the retroperitoneal tissue using a medial approach...

BACKGROUND: The branching of the inferior mesenteric artery and vein varies among individuals. Three-dimensional CT angiography is a less invasive modality than traditional angiographic examination to assess the artery and vein. OBJECTIVE: We aimed to demonstrate the clinical applicability of CT angiography by evaluating bifurcations of the inferior mesenteric artery and the positional relationship between the inferior mesenteric artery and vein. DESIGN: This was a prospective observational study of patients undergoing preoperative CT angiography...

Anatomical resection of segment VIII (SVIII) is one of the most difficult hepatectomies to perform. Although it is the best choice of surgical treatment for tumors located at SVIII, its feasibility can be compromised when the right hepatic vein (RHV) must be resected en bloc with SVIII. Herein we describe a case of a cirrhotic patient that was submitted to segmentectomy VIII in bloc with the main trunk of the RHV, due to hepatocellular carcinoma. The resection could only be performed because a well developed inferior right hepatic vein (IRHV) was present...

PURPOSE: Recently, the radiological concept of retroperitoneal interfascial planes has been widely accepted to explain the extension of retroperitoneal pathologies. This study aimed to explore embryologically based corroborative evidence, which remains to be elucidated, for this concept. METHODS: Using serial or semi-serial transverse sections from 29 human fetuses at the 5th-25th week of fetal age, we microscopically observed the development of the retroperitoneal fasciae and other structures in the retroperitoneal connective tissue...

Although several studies have reported that the peritoneum does not contribute to the formation of a fascia between the urogenital organs and rectum, Denonvilliers' fascia (DF), a fascia between the mesorectum and prostate (or vagina) in adults, is believed to be a remnant of the peritoneum. Remnants of the peritoneum, however, were reportedly difficult to detect in other fusion fasciae of the abdominopelvic region in mid-term fetuses. To examine morphological changes of the pelvic cul-de-sac of the peritoneum, we examined 18 male and 6 female embryos and fetuses...
