Porta- caval anastomosis is the communication between tributaries of portal vein and systemic veins. These communications form important routes of collateral circulation in portal obstruction. In the rectal region the superior rectal vein (portal) anastomoses with the middle and inferior rectal veins (systemic).Haemorrhoid is a pathological condition where rectal veins become dilated and tortuous as a result of portal hypertension. Arshas mentioned in our classics is a condition where in there is formation of mamsaankura and raktasrava from the gudamarga. This arshas may be compared with haemorrhoids where there is tissue prolapse and bleeding per rectum. This paper discusses about the importance of porta-caval anastomosis and its role in a pathological condition of haemorrhoid and its comparison with arsha, mentioned in Samhitas.

The most common cause for this is pathological condition may cause arsha. the pressure exerted on the rectal veins. During defecation when person puts pressure, the dilated rectal veins burst and start bleeding. This bleeding per rectum is similar to the raktasrava in arsha as mentioned by acharya Charaka. Also explaining about samprapti of arshas acharya Sushruta mentioned that, vitiated vatadi dosha either single or along with other doshas or along with rakta takes ashraya in main dhamani of shareera and through these dhamani moves towards guda and produces mamsaankura.

  • Magnetic Anastomosis Rings to Create Portacaval Shunt in a Canine Model of Portal Hypertension
    Journal of Gastrointestinal Surgery (2019) 23:218 4–2192 https://doi.org/10.1007/s11605-018-3888-5 ORIGINAL ARTICLE Magnetic Anastomosis Rings to Create Portacaval Shunt in a Canine Model of Portal Hypertension Hao-Hua Wang1,2,3 & Jia Ma4 & Shan-Pei Wang1,2,3 & Feng Ma2,3 & Jian-Wen Lu1,2,3 & Xiang-Hua Xu1,2,3 & Yi Lv1,2,3 & Xiao-Peng Yan 1,2,3 Received: 16 May 2018 /Accepted: 15 July 2018/Published online: 21Aug ust2018 # 2018 The Society for Surgery of the Alimentary Tract Abstract Purpose This study evaluated a novel magnetic compression technique (magnamosis) for creating a portacaval shunt in a canine model of portal hypertension, relative to traditional manual suture. Methods Portal hypertension was induced in 18 dogs by partial ligation of the portal vein (baseline). Six weeks later, extrahepatic portacaval shunt implantation was performed with either magnetic anastomosis rings, or traditional manual suture (n =9,each). The two groups were compared for operative time, portal vein pressure, and serum biochemical indices. Twenty-four weeks post- implantation, the established anastomoses were evaluated by color Doppler imaging, venography, and gross and microscopic histological examinations. Results Anastomotic leakage did not occur in either group. The operative time to complete the anastomosis for magnamosis (4.12 ± 1.04 min) was significantly less than that needed for manual suture (24.47 ± 4.89 min, P < 0.01). The portal vein pressure in the magnamosis group was more stable than that in the manual suture group. The blood ammonia level at the end of the 24- week post-implantation observation period was significantly lower in the magnamosis group than in the manual suture group.

  • Thrombosis of the Portal Vein with Recanalization in Hepatic Cirrhosis
    THROMBOSIS OF THE PORTAL VEIN WITH RECANALIZATION IN HEPATIC CIRRHOSIS CHARLES H. BROWN, M.D., Department of Gastroenterology RICHARD C. BRITTON, M.D.,* Department of General Surgery FRED F. WHITCOMB, JR., M.D.,f and RASIM TURKSEL, M.D.t Department of Gastroenterology CUTE thrombosis of the portal vein has been reported as a complication il occurring in from 10 to 20 per cent of patients with cirrhosis of the liver.1"9 Symptoms and findings vary in relation to the type of onset of thrombosis and to the stage of hepatic disease. Although the complication is relatively rare, the true incidence is difficult to determine because diagnosis usually is not made with certainty before the death of the patient. The dual purpose of this paper is to report thè case of a patient with hepatic cirrhosis in whom an acute portal vein thrombosis developed, proved by means of splenoportography both before and after recanalization, and to describe the nature of the symptoms that initially led us to suspect this diagnosis. Report of a Case A 39-year-old man was admitted to the hospital in November, 1959, because of anorexia, bloating, and intermittent cramping in the region of the umbilicus, of one year's duration. The abdominal pain had increased during the month before admission, having been so severe as to have awakened the patient at night several times. Three weeks before admission, jaundice without itching, tremulousness, and abdominal distention developed, and the urine became dark. The patient reported having consumed five or six highballs daily during the past 10 years, but there was no previous history of jaundice, hepatic disease, or ingestion of chlorpromazine hydrochloride.

T- 2:638-640 (Sept. 15) 1979. Five hundred four patients who had had hospital examinations were interviewed to find out how much information they had been given about the tests; their reactions before, during, and after the test; and any after effects. In 74% of cases the tests had been satisfactorily explained. Patients were told more about complicated procedures, such as cardiac catheterization, than about routine ones, such as venepuncture or barium meal examinations. The comments physicians made while performing the examinations were generally reassuring. About one half of the patients had pain or discomfort during the tests, and more complained of after effects. Only 5% said they would refuse the test again, though 36% said they would agree reluctantly. Hospitals might consider issuing information sheets to support the physician's explanation and to dispel myths. Localization of Gastrinomas by Transhepatic Portal Catheterization and Gastrin Assay.

Gastrinomas were localized by concurrent blood sampling in the hepatic vein and portal vein tributaries in ten of 12 patients with Zollinger-EIlison syndrome. Six patients were subsequently operated on: five had pancreatoduodenal resection and one had laparotomy at which metastases were found. Four of the resections were probably curative as the patients have done well without treatment since surgery, with concentrations of gastrin in serum near zero.
