A 2-year-old Standardbred colt was examined because of signs of abdominal pain of 12 hours' duration. Clinical signs of disease, including tachycardia and abdominal distention, and rectal palpation findings of distention and thickening of the ventral colon, were consistent with displacement or early strangulation obstruction of the large colon. Surgical exploration revealed volvulus of the large colon around an axis formed by the dorsal mesenteric attachment of the transverse colon. The cecum could be completely exteriorized and lacked the cecocolic ligament and dorsal mesenteric attachments. The dorsal mesenteric attachments of the right ventral and dorsal colons were also lacking. The viscera were repositioned, and the horse was discharged 13 days after surgery. The horse developed severe colic 6 months later and was euthanatized. Mesenteric volvulus and omental adhesions were found at necropsy. 相似文献

A young adult pregnant alpaca was presented with an acute episode of abdominal pain. Hematology revealed mild anemia, neutropenia with a degenerative left shift and moderate toxic changes in neutrophils, hyperfibrinogenemia, hypoproteinemia, and hypoalbuminemia. Abdominal ultrasound showed a small intestinal segment with severely increased wall thickness and collapsed lumen. Exploratory laparotomy revealed a markedly thickened 60 cm jejunal segment with reddened serosa from which a full-thickness biopsy and samples for bacterial culture were obtained. Histopathology revealed severe coccidian enteropathy with secondary bacterial enteritis. Anaerobic culture yielded Clostridium perfringens, while fecal sugar flotation yielded Eimeria macusaniensis and Eimeria punoensis. The alpaca was treated with broad-spectrum antimicrobial drugs, sulfadimethoxine, and anti-inflammatory drugs. The alpaca made a gradual recovery and had a term pregnancy. This communication demonstrates the potential pathogenicity of E. macusaniensis in adult alpacas. Coccidian enteropathy should be considered in adult alpacas with gastrointestinal signs including acute abdominal pain and hypoproteinemia. 相似文献

An 8-year-old potbellied pig was evaluated for anorexia, decreased fecal production, signs of depression, inappetence, and abdominal distension. During hospitalization, a tooth root impaction and abscess were diagnosed, and abdominal radiography revealed severely distended, gas-filled large and small intestines. Exploratory laparotomy revealed a stricture of the proximal centripetal loop of the spiral colon and megacolon of the proximal portion of the spiral colon and cecum. A side-to-side spiral colon anastomosis was performed to create a partial bypass of the spiral colon. The success of this procedure suggests that spiral colon bypass is a treatment option for spiral colon stricture formation in potbellied pigs. Spiral colon stricture formation should be considered as a differential diagnosis in geriatric potbellied pigs that are anorectic, have abdominal distension, and have decreased fecal production. 相似文献

An adult alpaca was presented because of abdominal pain and was diagnosed with an intestinal obstruction. The putative diagnosis at surgery was an intestinal obstruction caused by peritonitis and intra-abdominal adhesions. The cause of the inflammation was not determined at that time. The alpaca died soon after surgery from post-surgical complications and a peritoneopericardial diaphragmatic hernia that was not diagnosed until necropsy. 相似文献

A large granulosa cell tumor was believed to be responsible for causing obstruction and subsequent rupture of the small colon in a 10-year-old Quarter Horse mare. Two months earlier, a mass, tentatively diagnosed as granulosa cell tumor of the left ovary, had been identified by means of rectal palpation and ultrasonography. The mare was evaluated for clinical signs of acute, severe, abdominal pain, increased heart rate, cyanotic mucous membranes, clinical dehydration, with high PCV, leukopenia, and extreme abdominal distension. A large soft tissue mass and taut band that constricted the lumen of the small colon were palpable per rectum. Septic peritonitis was diagnosed on the basis of results of abdominocentesis. Exploratory surgery revealed extensive fecal contamination of the abdominal viscera, and the mare was euthanatized because of the resultant poor prognosis. At necropsy, the small colon was occluded by a taut, left broad ligament and the ovarian mass that was proved to be a granulosa cell tumor. The occlusion had caused impaction of the small colon, with subsequent perforation at the level of the broad ligament. 相似文献

The medical records of 13 horses with strangulated umbilical hernias were reviewed. Typical history included increased swelling, warmth, and firmness of the hernial sac. Enterocutaneous fistulas had developed in 2 horses. Four horses had signs of abdominal pain. Surgery was performed on all horses, and the hernia was reduced by an open reduction technique. Incarcerated tissue included omentum (1 horse), jejunum (5), ileum (4), cecum (1), and ventral colon (2). All horses survived and were discharged from the hospital. Follow-up information on 9 horses (5 to 52 months after discharge) revealed no complications in 6 horses. Of the remaining 3 horses, one horse was euthanatized 5 months after discharge because of laminitis. One horse had persistent drainage from the skin incision requiring removal of nonabsorbable suture material 8 months after discharge. One foal required a second surgery because of signs of abdominal pain 17 days after the initial surgery. The foal was euthanatized during surgery because of severe peritonitis secondary to anastomotic leakage. 相似文献

A 45‐day‐old foal was presented for abdominal pain. Examination revealed the presence of haemoabdomen. An exploratory celiotomy was performed that revealed a large tear on the visceral surface of the spleen. A splenectomy was performed without rib resection. An abdominal wall hernia and leucocytosis had developed by 6 weeks post surgery. A second celiotomy to repair the hernia and explore the cause of the leucocytosis was performed 10 weeks after the first surgery. A portion of the caecum and colon had become adhered to the body wall at the site of the hernia; these areas were resected and the hernia repaired with a polypropylene mesh. The filly made a good recovery and is currently in training. Splenic rupture should be considered in any horse showing signs of abdominal pain with ultrasonographic findings consistent with haemoabdomen. 相似文献

A 9-year-old pregnant Standardbred broodmare was evaluated for signs of mild abdominal pain, failure to defecate, and mild abdominal distention. Rectal examination revealed the leading edge of a small colon intussusception, and peritoneal fluid analysis indicated suppurative peritonitis. Surgical management, including reduction of the intussusception and small colon resection with end-to-end anastomosis, resulted in successful outcome (1-year follow-up evaluation). Postoperative complications including dehiscence of the ventral midline surgical incision and simple obstruction at the anastomosis site necessitated a second surgical procedure. Small colon intussusception is an uncommon cause of signs of abdominal pain and is similar to type-IV rectal prolapse. 相似文献

Four horses operated on for left dorsal displacement of the large colon (LDDLC) had major intraoperative or postoperative complications. One horse was euthanatized during surgery because of extensive necrosis of the large colon. Three horses that were discharged after surgical correction of LDDLC were readmitted with signs of abdominal pain between 5 weeks and 13 months after surgery. Two horses had recurrence of LDDLC, and the third horse had an omental adhesion attached to and obstructing the pelvic flexure. The displacements were corrected, the adhesion was broken down, and the horses were discharged. One horse was readmitted a third time 16 months after the second surgery and required a third surgical correction of LDDLC. 相似文献

This report describes the clinical course and the surgical findings in a 7‐day‐old foal referred for signs of abdominal pain. The foal underwent abdominal celiotomy due to the degree of pain unresponsive to medical treatment and, upon exploration, an ovarian pedicle was found to be wrapped around the small colon. The lesion was corrected, the foal recovered well from anaesthesia, and a 4 month follow‐up revealed no other signs of abdominal pain or complications. 相似文献

This paper describes the clinical signs and surgical treatment of 2 cases of dorsal displacement of the left ventral and dorsal colon. The condition, in which the colon becomes enclosed in the space bounded by the base of the spleen, the dorsal aspect of the suspensory ligament of the spleen (phrenicosplenic ligament), the left kidney and the adjacent body wall, is characterised by moderate to severe pain, minimal signs of shock, no response to medical therapy and a tendency for a ventral midline abdominal paracentesis to enter the spleen. Both horses recovered after surgical replacement of the colon, one case requiring a second laparotomy because of a recurrence of the displacement. 相似文献

Colopexy of the left ventral colon to the abdominal wall was performed in 4 horses with recurrence of large-colon displacement or volvulus. Horses were discharged between 5 and 27 days after surgery. At follow-up evaluation (mean, 10.5 months; range, 7 to 13 months) of the horses, none had recurrence of signs of abdominal pain, and all had normal body weight. Three horses were exercised regularly; signs of abdominal pain were not observed. 相似文献

During a 28 month period, 82 horses with clinical signs of abdominal pain were examined for left dorsal displacement of the large colon (LDDLC) using percutaneous ultrasound. Left dorsal displacement of the large colon was diagnosed when a gas echo dorsal to the spleen obliterated the dorsal splenic border, or when the colon was observed lateral to the spleen. In 42 horses, ultrasound confirmed a diagnosis of LDDLC and 40 horses had no evidence of LDDLC. There were five false negative results and no false positives. In four horses with LDDLC, the colon was displaced between the spleen and body wall; three of these colic episodes resolved with medical therapy and the fourth required a celiotomy to relieve a sand impaction. The remaining 38 horses had a renosplenic entrapment; surgical correction was elected in 4 horses, 21 horses were corrected by a nonsurgical rolling procedure, 12 were corrected at surgery after an unsuccessful rolling attempt, and one was corrected by rolling but required surgery later because of an additional lesion. Percutaneous abdominal ultrasound was a valuable aid in the diagnosis of LDDLC and in confirming correction of the displacement after a nonsurgical rolling procedure. 相似文献

Malignant neoplasia in 4 alpacas was characterized by acute onset of clinical signs and rapidly deteriorating condition. Postmortem examination revealed metastatic or multicentric neoplasia in the abdominal organs of alpacas 1, 3, and 4 and an extensive thoracic mass in alpaca 2. Immunohistochemical stains supported a diagnosis of B-cell lymphosarcoma in alpacas 1-3 and a neuroendocrine neoplasm in alpaca 4. 相似文献

A one‐day‐old Thoroughbred colt foal was presented for assessment of abdominal pain and reduced urine output. Physical examination of the foal revealed marked abdominal distension, mild tachycardia, tachypnoea and congested mucous membranes. A marked anechoic peritoneal effusion, intestinal hypomotility and mural thickening of the large colon were detected sonographically. Serosanguinous fluid was obtained by abdominocentesis. After haemodynamic stabilisation, the foal underwent general anaesthesia and exploratory laparotomy and a 720° volvulus of the large colon at the sternal and diaphragmatic flexures was identified. After correction of the volvulus, the intraoperative findings were consistent with nonviability of the affected portion of the colon. The owner declined partial colon resection and elected for euthanasia of the foal. Although rare in neonatal foals, large colon volvulus should be considered in foals with signs of abdominal pain, abdominal distension and ultrasonographic findings of colonic mural thickening and luminal distension. 相似文献

A seven-month-old male alpaca (Lama pacos) with signs of abdominal straining was examined. A fluid-filled structure was palpable in the mid-abdominal region, and ultrasonography revealed a hydronephrosis of the right kidney, with an associated mega-ureter. The affected kidney was removed and the clinical signs resolved. Histological examination of the kidney revealed the unusual congenital abnormality of ureteral duplication. It is suggested that the hydronephrosis developed as a result of this underlying condition. 相似文献

This report describes caecal intussusception in two young half-sibling Standardbred horses. Both horses presented showing signs of low-grade abdominal pain. The horses remained haemodynamically stable despite signs of abdominal pain and associated tachycardia. Exploratory celiotomy was undertaken in both horses due to persistent abdominal pain and a poor response to administration of analgesic medications. Exploration of the abdomen revealed caeco-caecal intussusception in one horse and caeco-colic intussusception in the other horse. An underlying cause for caecal dysfunction and subsequent intussusception was not identified in either patient. Manual reduction of the intussusception was successful in both cases. The horses recovered uneventfully from surgery. 相似文献

Four miniature foals admitted with signs of progressive nonresponsive abdominal pain and no fecal production had fecalith impaction of the small colon. Duration of clinical signs ranged from 10 hours to 5 days. Removal of the fecalith via small colon enterotomy was a successful treatment in all 4 cases. Miniature foals may be predisposed to fecalith impaction of the small colon. If a miniature foal has signs of progressive nonresponsive abdominal pain, fecalith impaction needs to be considered. Surgical correction may be required. 相似文献

A 1-month-old cria (Lama pacos) was presented because of depression, anorexia, and diarrhea for 3 days. Although treated for enteritis (intravenous fluids and antibiotics), the cria's condition deteriorated. An abdominal radiograph revealed radiodense materials in the 3rd compartment and intestines. The cria died due to sand impaction of the spiral colon. 相似文献

CASE DESCRIPTION: A 1-month-old female alpaca was examined because of progressive clinical signs consistent with an intracranial lesion. CLINICAL FINDINGS: Clinical signs included signs of depression, lethargy, tetraparesis, and neck weakness. Two large isointense intracranial masses could be seen on T1-weighted magnetic resonance images. On T2-weighted images, the masses contained concentric rings of hypointense and hyperintense material. TREATMENT AND OUTCOME: 2 abscesses were removed via a craniotomy that incorporated removal of the sagittal crest and surrounding skull and transection of the sagittal sinus. The bony deficit was replaced with polypropylene mesh. The alpaca recovered within 2 weeks and was fully integrated into the herd within 1 month after surgery. CLINICAL RELEVANCE: Findings indicated that surgical removal is a feasible means of successfully treating intracranial abscesses in juvenile alpacas. 相似文献
