Abstract: The main purpose of this study was to convey a more precise explanation of the arterial supply of the intestinal tract of the goat. Fifteen adult healthy goats were used. Immediately after slaughtering of the goat, the thoracic part of the aorta (just prior to its passage through the hiatus aorticus of the diaphragm) was injected with gum milk latex (colored red) with carmine. The results showed that the duodenum was supplied by the cranial pancreaticoduodenal and caudal duodenal arteries. The jejunum was supplied by the jejunal arteries. The ileum was supplied by the ileal; mesenteric ileal and antimesenteric ileal arteries. The cecum was supplied by the cecal artery. The ascending colon was supplied by the colic branches and right colic arteries. The transverse colon was supplied by the middle colic artery. The descending colon was supplied by the middle and left colic arteries. The sigmoid colon was supplied by the sigmoid arteries. The rectum was supplied by the cranial; middle and caudal rectal arteries. Keywords: Anatomy,Arteries, Goat, Intestine I. Introduction Goats characterized by their high fertility rate and are of great economic value; being a cheap meat, milk and some industrial substances. -

Colon Operative Standards
282 SECTION IV | COLON F G E F FIGURE 16-7 (Continued). patients with hereditary nonpolyposis colon cancer, as they have a higher incidence of synchronous and metachronous colonic tumors than do patients with sporadic colorectal cancer. As calculated by life table analysis, the risk for metachronous cancer among patients with hereditary nonpolyposis is as high as 40% at 10 years. Simi- larly, for colon cancer patients with familial adenomatous polyposis, surgical resec- tion should consist of either total abdominal colectomy or total proctocolectomy. The choice between these two operations depends on the burden of polypoid disease in the rectum and the patient’s preference for close surveillance. 7,8,9 Finally, individuals who develop colon cancer in the setting of long-standing ulcerative colitis require a total proctocolectomy. The oncologic principles of colon cancer surgery as outlined in this chapter, including the attention to surgical margins and the need for proximal vascular ligation, should be adhered to bilaterally, not just for the portion of colon in which the tumor has been identifi ed.10,11 3. PROXIMAL VASCULAR LIGATION AND REGIONAL LYMPHADENECTOMY Recommendation: Resection of the tumor-bearing bowel segment and radical lymphadenectomy should be performed en bloc with proximal vascular ligation at the origin of the primary feeding vessel(s).

Mukka, Mangalore E-mail: [email protected], Ph: 0091 08904390833 ABSTRACT: The surgical procedures like appendicectomy, demands a precise knowledge of vascular anatomy of ileocolic region. The aim of this study is to study the arterial supply of the appendix, findings of which may reveal more anatomical facts about the arteries of appendix and their variations. Total 52 specimens of caecum and appendix with their arteries intact were collected, cleaned and dissected. The ileocolic artery and its branches to the appendix were traced carefully and observations were recorded. The ileocolic artery arises independently from superior mesenteric artery in 96.88% of cases and ends by dividing into superior and inferior division in 93.76% of cases. The appendicular artery arises from inferior division in 46.88%, ileal branch 28.13%, ileocolic artery 18.75% and from arterial arcade in 6.25% of cases. 21.87% of cases showed additional appendicular artery. KEYWORDS: Caecum, appendix, ileocolic artery, appendicular artery. INTRODUCTION: Vascular anomalies always pose a great challenge to the anatomists and surgeons. The surgical trauma to the sustaining blood vessels is irreparable and lead to fatal necrosis of the part involved. Surgical procedures like appendicectomy, which is one of the common surgical procedures in case of appendicitis, appendicular carcinoid tumors etc. -

Abstract: Background and Objectives: Knowledge of arterial variations of the intestines is of great importance in visceral surgery and interventional radiology. Materials and Methods: An unusual variation in the blood supply of the descending colon was observed in a Caucasian female body donor. Results: In this case, the left colic artery that regularly derives from the inferior mesenteric artery supplying the descending colon was instead a branch of the common hepatic artery. Conclusions: Here, we describe the very rare case of an aberrant left colic artery arising from the common hepatic artery in a dissection study.

The Blood Supply of the Vermiform Appendix in Nigerians
J. Anat. (1968), 102, 2, pp. 353-361 353 With 6 figures Printed in Great Britain The blood supply of the vermiform appendix in Nigerians TORIOLA F. SOLANKE Department of Surgery, University College Hospiral, lbadan, Nigeria There is no general agreement in the literature about the arterial blood supply of the vermiform appendix. Published papers and standard text-books contain differing statements about the number of arteries which supply this organ and also about the immediate derivation of these vessels (Table 1). Some authoritative sources such as Koster & Weintrob (1928), Bruce, Walmsley & Ross (1964), and Grant & Basmajian (1965) state that the appendix is supplied by only one artery; but other workers (Shah & Shah, 1946; and Wakeley, Harmer & Taylor, 1960) claim that it is supplied by more than one vessel. Little information is available in the literature about the distribution and pattern of branching of the appendicular arteries. In view of the discrepancies in the literature about the anatomy ofthe vascular supply ofthe appendix and the apparent rarity of appendicitis among Africans (Short, 1946; Kerr, 1957; Bailey & Love, 1965), this investigation was undertaken to determine the origin, patterns of branching and anastomoses of the appendicular arteries in Nigerians. Previous studies on the blood supply of the appendix were carried out either as part of routine dissections of injected cadavers or by the direct injection of dye into the main appendicular artery. With these methods of study there might be difficulty in defining clearly the exact origin of the main appendicular artery, and accessory vessels to the appendix might be missed. In this study, the arterial supply of the appendix was demonstrated by injecting a suspension of barium sulphate into the superior mesenteric artery, and the pattern of distribution was studied by radiological and histological examinations. -

World Journal of Surgical Oncology (2019) 17:16 https://doi.org/10.1186/s12957-019-1561-4 RESEARCH Open Access Variations in right colic vascular anatomy observed during laparoscopic right colectomy Chuying Wu†, Kai Ye*†, Yiyang Wu, Qiwei Chen, Jianhua Xu, Jianan Lin and Wengui Kang Abstract Background: This study aimed to analyze right colonic vascular variability. Methods: The study included 60 consecutive patients who underwent laparoscopic radical right colectomy and D3 lymph node dissection for malignant colonic cancer on the ileocecal valve, ascending colon or hepatic flexure (March 2013 to October 2016). The videos of the 60 surgical procedures were collected. Variations of right colonic vascular anatomy were retrospectively analyzed based on 60 high-resolution surgical videos of laparoscopic surgery. Results: The superior mesenteric artery and vein were present in all cases; 95.0% (57/60) had the superior mesenteric artery on the left side of the superior mesenteric vein. The ileocolic artery and vein occurred in 96.7% (58/60) and 100% (60/60) of cases, respectively; 50.0% (29/58) had the ileocolic artery passing the superior mesenteric vein anteriorly. Thirty-three (55.0%) cases had a right colic artery, and 2 (3.33%) had a double right colic artery; 90.9% (30/36) had the right colic vein passing anterior to the superior mesenteric artery. Fifty-six (93.3%) cases had a right colic vein; 7 (12.5%) had a right colic vein accompanied by a right colic artery, 66.1% (37/56) had the right colic vein draining into the gastrocolic trunk of Henle, 23.2% (13/56) had the right colic vein directly draining into superior mesenteric vein, and 10.7% (6/56) had one right colic vein draining into the superior mesenteric vein and the other into the gastrocolic trunk of Henle. -
Arteries of the Abdomen
Arteries of the Abdomen Arteries that supply the abdominal organs and abdominal wall structures originate from the abdominal aorta. About half of resting cardiac output flows through these vessels. The abdominal arteries are all in pairs, except for the superior and inferior mesenteric arteries, the celiac trunk, and the median sacral artery. Major Arteries of the Abdomen Artery Area Supplied Description Inferior Inferior surface of Arise from the aorta just below the diaphragm phrenic diaphragm arteries Celiac trunk Branches supply Large unpaired artery divides into common hepatic, splenic, and various abdominal left gastric arteries; A branch of the common hepatic artery, the organs gastroduodenal artery, becomes the hepatic artery proper, whose branches supply the liver; Gastroduodenal and splenic arteries give rise to the right and left gastroepiploic arteries, respectively, that supply the greater curvature of the stomach Superior Branches supply the Large unpaired artery; Branches: intestinal arteries (supply most of mesenteric duodenum, pancreas, small intestine), ileocolic artery (appendix, cecum, and ascending artery and parts of the colon), right and middle colic arteries (part of transverse colon) small and large intestines Middle Adrenal glands Adrenal glands are supplied by the middle suprarenal arteries, as suprarenal well as the superior suprarenal branches of the inferior phrenic arteries arteries and the inferior suprarenal branches of the renal arteries Renal Kidneys The left renal artery is shorter than the right arteries -

ABSTRACT The vermiform appendix is a part of large intestine, situated in right iliac fossa. It is a vestigeal organ in humans. This study was done 50 adult cadavers and spontaneously aborted fetal specimens. The anatomical variations were photographed, tabulated and compared with previous studies. Bacterial infection of appendix known as appendicitis is an emergency condition in all age groups. This is treated by removal of it known as appendicectomy. Detailed knowledge about the normal and variant anatomy is important for the surgeons during the surgery. The anatomical knowledge is also useful to the radiologist for diagnosing the appendicular artery in angiograms. KEY WORDS: Vermiform Appendix, Vestigial, Appendicectomy.
