junction for annular adenocarcinoma in two dogs Sydney Endoscopic mucosal snare polypectomy for treatment of a colorectal polypoid adenoma in a dog Coleman (Berent/ Weiss) AMC JAVMA 2014 2-cm-diameter sessile polypoid mass was located approximately 6 cm orad to the anus infused saline under the base of the polyp because of the sessile, rather than pedunculated, base. The entire polyp was successfully removed with endoscopic guidance. clinical signs resolved immediately serial rectal ex- aminations were performed over the following 36 months with no palpable evidence of recurrence.

A Novel Surgical Stapling Technique for Rectal Mass Retrospective Analysis Swiderski (Withrow) Colorado 2009 7 dogs with up to 4cm masses with a 3mm vascular TA. Mostly carcinomas Only two masses were identified with clean margins; 6/6 free of clinical signs at a mean time of 498 days. Four of these six dogs had a digital rectal examination performed by the referring veteri- narian at a mean of 564±174 days; no recurrence of rectal masses was noted. Lower clean margin rate than Danova, but aimed for lesser margins. No tenesmus/ bleeding compared with 6/23 from Danova Predisposing Factors for Colonic Torsion/Volvulus in Dogs: A Retrospective Study of Six Cases Gagnon Guelph JAAHA 2013 6 dog restrospective history, clinical signs, and physical examination findings in the current study were not specific to colonic torsion. Abdominal effusion was not reported Three of six dogs had entrapment and strangulation around the gastropexy site at the time of surgery and a 4th (euthed)dog had also had a gastropexy. All operated dogs survived to discharge (3/5 had colopexy) is better than previouslyreported and accredited to rapid ex lap. Prelimerinary clinical observations on the use of piroxicam in the management of rectal tubulopapillary polyps Knottenbelt Dick JSAP 2000 Authors previously identified Cox expression by many rectal tumours. 8 dogs with histologically benign rectal masses treated with tenesmus and faecal mucus production was reduced in all cases rectal mass appeared to have reduced in size at follow-up endoscopy after four to six weeks of
piroxicam suppositories. Reassessed with colooscopy piroxicam therapy in all dogs. Subtotal colectomy with surgical stapling instraments via a trans caecal approach for treatment of acquired megacolon in cats Kudish (Pavletic) Tuffts/ Angell Vet Surg 1993 15 cats clinical for megacolon treated with EEA placed via caecum and caecum closed with TA stapler. 2 cats had bleeding requiring transfusion Diarrhoea and tenesmus lasting up to one month No long term complications Subtotal colectomy by rectal for treatment of idiopathic megacolon in 2 cats Barnes (Furneaux) Bishop’s Stortford Veterinary Hospital, CVJ 2012 2 Cat case report of combined abdominal approach and pull through via anal intussusception as per swensons No follow-up provided Comparison of a Biofragmentable Intestinal Anastomosis Ring With Appositional Suturing for Subtotal Colectomy in Normal Cats Huss Missouri Vet Surg 1994 6 rings Vs 6 sutured colectomies in healthy cats Rings = 87.5% polyglycolic acid polymer and 12.5%barium sulfate Histo at 30 days anastomosis rings fragmented 12. days after implantation and passed in the stool 4 days later without clinical signs in five of six cats. There were no statistically significant differences in postmortem gross anastomosis grades, or percent of lumenal stricture. Histologically, there was an increased muscular inversion in the anastomoses performed using the frag- mentable ring and an increased muscular eversion in the sutured anastomoses 11/12 started passing a formed stool by the end of the 30-day study period
Laparoscopic Colopexy in Dogs Zhang China JVetMedSci 2013 eight healthy mixed-breed dogs Colopexy was accomplished by use of a laparoscopic technique without major intra- operative and postoperative complications. A permanent adhesion between the colon and the abdominal wall was observed. Rectal lymphoma in 11 dogs – a retrospective study Van den Steen AHT JSAP 2012 Heterogenous treatments with surgery/ chemo Median survival time was not reached, and there was an overall mean survival time of 1697 days chemotherapy lived significantly longer than dogs that did not receive chemotherapy (2352 Vs 70 days) All tested were “B” which may contribute to better prognosis. A Review of 18 Cases of Feline Colonic Adenocarcinoma Treated with Subtotal Colectomies and Adjuvant Carboplatin Arteaga Pacific (ca) JAVMA 2012 THe outcome of subtotal colectomy and adjuvant carboplatin in 18 client-owned cats for colonic adenocarcinoma Surgical margins were complete in all 18 cases. Cats without distant metastasis survived 340 days and cats with distant metastasis lived 200 days. 269 days overall.
