Intestinal evisceration injuries are devastating occasions due to trauma or dehiscence of surgical incisions. Often if the occasion is not known and also treated immediately, exposed intestines are severely contaminated and also damaged from trauma or self–mutilation by the patient. Although many kind of of these patients cannot be conserved because of huge devitalization of bowel, additional injuries and/or financial constraints, some of these patients are treatable and also have the right to make it through with the aid of aggressive clinical and surgical management and committed owners.
Tenets of therapy include:Emergency triage—Treatment for shock, assessment and also administration of additional injuries, security of the exposed abdominal organs, and initiation of antimicrobial treatment.Wound decontamination—Convariation of the dirty wound into a clean contaminated wound and also momentary clocertain of the abdoguys for surgical prep.Surgical exploration—Identification and also definitive treatment of lesions affecting the abdominal organs, abdominal lavage, society sampling, and also placement of closed suction drains, if applicable.Post–operative management—Broad spectrum antimicrobial treatment tailored by culture results, abdominal drainage and/or lavage, liquid and also colloid support, pain monitoring, and also early on refeeding.
Chance, a 4 ½ year old male neutered border collie was referred to DoveLewis for emergency review and therapy of an intestinal evisceration injury that had arisen when the dog fell 15 feet from a cliff to a ledge while on a pilgrimage in the Columbia Gorge area. Chance might not walk and was hoisted to safety and security with a rope. At that allude, evisceration of intestines was noticeable. Luckily several vets were at the website and also able to immediately cover the contaminated segments so that Chance might be transported to a regional hospital.Emergency triage and stabilization
Chance obtained emergency stabilization treatments at Alpine Veterinary Hospital consisting of rebandaging, IV catheter and also resuscitative fluids, pain drugs, corticosteroids and antibiotics. He was then transferred to DoveLewis for definitive review and treatment. On admission to DoveLewis, Chance was responsive, yet recumbent. He did not show up to have any type of musculoskeletal or neurologic injuries. Vital indicators were relatively secure, many thanks to aggressive initial stabilization by the referring DVMs. The bandage was rerelocated and also brief inspection revealed evisceration of multiple loops of small intestine from the caudal abdoguys. The bowel was dark red, slightly dry and also extended via dirt and also plant debris. The bowel was spanned via wet lap pads, and also the abdoguys rewrapped to await surgical procedure.
Initial diagnostics contained CBC and also chemistry. Urinalysis might not be performed due to the place of the injury and also eviscerated intestines. Blood tests revealed Chance was anemic, leukopenic, thrombocytopenic and panhypoproteinemic. He was mildly hypocalcemic (ionized and also corrected for low TP) and also hypokalemic. Thoracic radiographs were within normal boundaries.
Initial treatment contained fluid and electrolyte resuscitation, antibiotic administration, colloid assistance, and pain regulate via fentanyl CRI. He was placed on consistent ECG, blood push and also pulse oximetry monitoring and was blood typed and cross matched.Wound decontamination
Chance was moved to surgical prep, preoxygenated, and then anesthetized with etomidate. The fentanyl CRI was ongoing at an correct surgical price to minimize use of inhalant anesthesia. A double lumen central venous catheter was placed to allow administration of fluids (crystalloids and also colloids), blood transfusions, medications and to allow for intraoperative venous sampling. At the exact same time, the abdominal bandage was rerelocated and also surgical preparation began.
Multiple loops of jejunum were herniated via a 4–5 cm midline, Z shaped body wall rent simply rostral to the prepuce. A main flap of skin was strangulating one 38 cm loop of bowel, and a number of other smaller segments (9 cm and also 6 cm) were avulsed from their blood supply. The exposed omentum, bowel, and also surrounding skin were extremely contaminated through dirt, plant debris, and hair. The bowel and also neighboring skin were rinsed via 2 L heat saline to remove loose debris. The abdominal haircoat was shaved. The strangulating area of skin was reduced to release the bowel. The three necrotic sections of bowel were double clamped then double ligated/transsolved and also the segments removed. Segment ends were trimmed of exposed mucosa to preclude the need for invariation of each finish, and also therefore decrease operative time.
Where blood vessels were still undamaged, they were ligated. The exposed, contaminated omentum was exteriorized a secondary 3 cm then the omentum separated, clamped, ligated via 2–0 maxon, and also the contaminated percentage removed. The remaining exposed bowel and omentum were lavaged via an additional 2.5 L saline and debris manually debrided with moistened lap sponges. The decontaminated healthy and balanced bowel and omentum were then returned to the abdomales and the rent closed with skin staples to permit for surgical preparation of the abdominal skin. A urinary catheter through closed collection system was inserted aseptically and also a sample conserved for urinalysis. A stormy prep was performed via chlorhexidine scrub/solution and the patient moved to the operating room.
Staples were removed from the body wall rent and also a midline abdominal incision was made founding at the body wall rent and also extfinishing to the xyphoid. It showed up that Chance had actually been impaled during his autumn dvery own the cliff, causing the rent in the body wall and also damages to retroperitoneal tworries and caudal abdominal structures. Tright here was a 5–6 cm rent in the retroperitoneal room just caudal to the left kidney, through hematoma formation approximately the kidney. The ureteral mesentery was torn however the ureter showed up intact. The kidney was normal in size and also color, yet pulses were not digitally palpable. The colonic mesentery was torn in the mid–descfinishing colon approximately 15 cm from the junction via the transverse colon. One vein was actively bleeding and also numerous others were avulsed however the colon color was normal. The actively hemorrhaging vein was in close applace through the staying arterial branch of the left colic artery providing the damaged segment. It was ligated with 6–0 prolene taking treatment not to damage the artery. The 3 locations of bowel wright here segments of contaminated and also necrotic bowel were formerly removed were inspected. In addition, an additional 18 cm of jejunum/proximal ileum showed up devitalized. The formerly exposed bowel and also omentum were markedly erythematous however the remainder of the abdomales was normal in shade. Gross contamination of the abdominal cavity was reasonably minimal. Chance’s owners were contacted intraoperatively and also informed of the require for substantial tiny intestinal rearea (about 65%) and also warned of potential complications consisting of short bowel syndrome. They chosen to proceed with treatment.
The bowel was exteriorized and examined for potential anastamosis sites. The distal 15 cm of jejunum and 2 cm of ileum were devitalized. There were several brief segments of formerly contaminated and also erythematous bowel in in between the already resected locations, yet in order to limit the number of anastamoses and remove as much grossly contaminated tproblem as feasible, the resection was extfinished aborally to the ileum and orally 64 cm from the junction with the duodenum and also a single finish to finish jejunoileal anastamosis percreated (The colonic mesenteric rent was closed. The abdoguys was lavaged via 2.5 L heat saline then gloves, instruments and also drapes were adjusted.
The abdoguys was lavaged via an additional 3 liters of warm saline and also a swab taken for culture and also sensitivity. Two fenestrated, closed suction, Jackson Pratt drains were inserted through the body wall into the cranial and also caudal aspects of the abdomales and also secured with purse string and Chinese finger trap sutures. The skin and body wall rent were sharply debrided then the incision closed consistently. The entire procedure took 3 hours and 45 minutes.Post–operative management
At the moment of this report, Chance was 10 weeks post–op. He is bright and alert and also ago to normal task He has loose feces, presumably because of considerable tiny bowel resection, but is maintaining his weight conveniently. His owners report that they are incredibly satisfied via the outcome. Many patients that undergo considerable tiny bowel resection take numerous months to adjust to shortened bowel size and also some call for chronic administration with a low fat low residue diet. According to a recent study, the percentage of bowel resected (from 50 to 90 percent), does not substantially affect outcome and a lot of patients have actually a satismanufacturing facility outcome.

Ideal triage at the event website, immediate treatment at the neighborhood hospital, then aggressive stabilization, decontamination and also repair steps at DoveLewis (combined through one incredibly difficult dog!) all functioned together to effect a great outcome in this case. We would certainly choose to say thanks to the veterinarians at Alpine Veterinary Hospital for the referral of this extremely challenging situation.
