  • 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).

  • Concurrent Origin of Right Gastroepiploic and Left Colic Arteries from Inferior Pancreaticoduodenal Artery: Rare Variation of Splanchnic Anastomosis
    DOI: 10.5958/2319-5886.2015.00142.3 International Journal of Medical Research & Health Sciences www.ijmrhs.com Volume 4 Issue 3 Coden: IJMRHS Copyright @2015 ISSN: 2319-5886 Received: 27th Apr 2015 Revised: 10th May 2015 Accepted: 25th May 2015 Case report CONCURRENT ORIGIN OF RIGHT GASTROEPIPLOIC AND LEFT COLIC ARTERIES FROM INFERIOR PANCREATICODUODENAL ARTERY: RARE VARIATION OF SPLANCHNIC ANASTOMOSIS *Mutalik Maitreyee M Assistant Professor, Department of Anatomy, MIMER Medical College, Talegaon Dabhade, Pune, India *Corresponding author email: [email protected] ABSTRACT In the present case, inferior pancreaticoduodenal artery, the first branch of superior mesenteric artery, was exceptionally giving rise to right gastroepiploic artery and left colic artery simultaneously. Right gastroepiploic artery is a branch of foregut artery, while left colic artery is a branch of hindgut artery. Concurrent origin of branches of foregut as well as hindgut arteries from a midgut artery i.e. superior mesenteric artery is very rare. Usual left colic artery from inferior mesenteric artery was also present but was supplying smaller area than usual. It can be explained as persistence of unusual channels and obliteration of usual ones along the dorsal splanchnic anastomosis during the embryonic development. The field of vascularization of superior mesenteric artery was extended beyond its usual boundaries both proximally as well as distally, which is clinically important as unawareness of the variations may lead to significant morbidity and mortality. Keywords: Bypass graft, Colic artery, Gastroepiploic artery, Pancreaticoduodenal artery, Splanchnic anastomosis, Mesenteric artery INTRODUCTION Fields of vascularization of celiac trunk (CT), gastroduodenal artery (GDA), arising from hepatic superior mesenteric artery (SMA), and inferior branch of CT (foregut artery).

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.

  • Variations in Right Colic Vascular Anatomy Observed During
    Wu et al. 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.

  • A Phylogenetic and Ontogenetic Perspective of the Unique Accumulation of Arterial Variations in One Human Anatomic Specimen
    medicina Article A Phylogenetic and Ontogenetic Perspective of the Unique Accumulation of Arterial Variations in One Human Anatomic Specimen Bettina Pretterklieber * and Michael L. Pretterklieber Division of Anatomy, Center for Anatomy and Cell Biology, Medical University of Vienna, A-1090 Vienna, Austria; [email protected] * Correspondence: [email protected] Received: 31 July 2020; Accepted: 1 September 2020; Published: 4 September 2020 Abstract: Background and objectives: Anatomical dissection is an indispensable means of acquiring knowledge about the variability of the human body. We detected the co-existence of several arterial variations within one female anatomic specimen during routine anatomical dissection. The aim of this study was to evaluate if this status is a regular pattern in any of other vertebrates. Materials and Methods: Besides of a meticulous anatomic dissection, we performed a literature review concerning the frequency, the phylogenesis, and ontogenesis of all of these variations. Results: Exceptionally, the middle colic artery arose from an extraordinarily divided celiac trunk. The kidneys received three polar arteries. On the left side, a corona mortis replaced the obturator artery. The aortic arch gave rise to a bicarotid trunk, and the right subclavian artery originated and coursed as a typical lusorial artery leading to a non-recurrent laryngeal nerve on the right side. Furthermore, variations of the branches of the thyrocervical trunk were found to be present. Extraordinarily, in their cervical portion both internal carotid arteries gave rise to two arteries each. All of these variations developed within two to three weeks, around the sixth week of gestation. It was not possible to ascribe all or even one of the variations to a singular species of vertebrates.

  • An Unusual Case of Colon Vascularization by the Inferior Mesenteric Artery Um Caso Incomum De Vascularização Do Cólon Pela Artéria Mesentérica Inferior
    CASE REPORT An unusual case of colon vascularization by the inferior mesenteric artery Um caso incomum de vascularização do cólon pela artéria mesentérica inferior 1 1 1 Serghei Covanțev *, Natalia Mazuruc , Olga Belic Abstract In this article we present a rare variant in which the large intestine was vascularized by the inferior mesenteric artery. It was encountered during macro and microscopic dissection of the cadaver of a 63-year-old woman at a university department of human anatomy. In this case, the ascending, transverse, descending, and sigmoid colon and rectum were vascularized by the inferior mesenteric artery, whereas the small intestine, cecum and appendix were supplied by the superior mesenteric artery. Keywords: inferior mesenteric artery variation; accessory middle colic artery; accessory left colic artery.
