“NOTES”
Case series of 6 horses who underwent transluminal endoscopy hybrid procedure for bilateral ovariectomy
-successful in all 6 mares with mean surgical time of 70 min
-complication: ovary dropped into abdomen during vaginotomy extraction, one mare developed an adhesion between the bladder and the vaginotomy site.
Surgical Details:
-standing in stocks
-ultrasound probe protected in a sterile rectal sleeve was introduced vaginally to assist visualization and surgical planning of vaginotomy. Doppler images were obtained to determine the location of the vaginal branch of the internal pudendal and uterine branch of the urogenital arteries
-Closed, straight Mayo scissors were used to penetrate the cranial left vaginal wall at approximately the 8–10 o’clock position 2 cm lateral to the cervix during laparo- scopic visualization. The vaginotomy was enlarged by ret- racting opened Mayo scissors from the abdominal space through the vaginal wall to create an approximately 4-cm long incision by blunt stretching. A 70-cm long esophageal foreign body forceps (Storz) (Figure 2) was introduced through the vaginotomy site, to grasp and stabilize the ovary while hemostasis and transection of the ovarian pedi- cle was achieved with a 10 mm, 37 cm length blunt tip vessel sealing device.
-vaginotomy incision was not closed
-Mares were stall-confined for 3 days postoperatively, then transferred to 23 square meter paddock turnout for 2 weeks.

“Standing lap scirrhous cord”
-complete resection of infected seprmatic cord achieved without intraoperative complications
-6 horses had intraabdominal adhesions involving ascending colon (4 cases) and descending colon (2 cases). Post op: minor incisional swelling (2/12) and emphysema (3/12) at the laparoscopic portals were observed.
-All horses survived to discharge
-At 3 months, wound had completely healed.

“CT foals, ribs”
-22 foals underwent surgical repair of rib fractures after preoperative CT
-21 foals had repair without CT
-Ultrasound and CT findings were different in number and location of fractured ribs in 76% of foals.
-More cranially positioned ribs were found as fractured with CT compared to ultrasound.
-Survival to discharge improved when foals underwent CT (91%) compared to no CT (60%)

“Ureteropyeloscopic removal of nephrolith”
*Hackett on paper
-The ureteropyeloscopic removal of a nephrolith from the left renal pelvis was completed. No complications were appreciated following the proce- dure, and the horse was able to return to athletic activity within 2 weeks.
-2 mm working channel diameter endoscope was passed through the PU into the bladder. The left ureteral opening was visible and a snare was advanced via the endoscopic working channel into the ureter as a guide for passage of the endoscope. Upon advancement of the endoscope, the nephrolith became visible within the renal pelvis.

“return to racing, repair of MCP/MCT condylar fxs”
-older horses, fillies, fractures of forelimbs, and complex, complete, displaced or fractures with concurrent proximal sesamoid bone fracture were negatively associated with a return to racing.
-Colts and geldings were 3 and 4 X more likely to race than fillies
-Hindlimb, incomplete or non propagating fractures were 4, 5, and 4 X more likely to race than those with a forelimb, complete or propagating fracture respectively.

“CT assessment, subchondral bone, lateral condylar fx”
“Computed tomographic assessment of fracture characteristics and subchondral bone injury in Thoroughbred racehorses with lateral condylar fractures and their relationship to outcome”
-66% of horses raced after surgery. Horses with sesamoid bone fractures, MC3/MT3 comminution, articular fragmentation were less likely to race post-operatively
-concurrent subchondral bone injury did not affect outcome
-Complete versus incomplete fractures and fillies less likely to race post-operatively

“3 treatments, SBC, TB”
-73% of TB raced post-operatively
-72% treated with arthroscopic debridement raced
-84% treated with intralesional MSC raced
-68% treated with intralesional corticosteroids raced
Sex, limb, and lesion size had no effect on ability to start a race. Slight trend toward increasing lesion size reducing probability of racing.

“hand scrub techniques prior to application of alcohol based hand rub”
Results:
-Two hours after surgery commenced, the participants of groups that performed a hand preparation had lower total CFUs than those that did not perform a hand preparation (P = .001).
-In particular, the number of CFUs was lower when ABHR (alcohol) was performed after application of pHN compared to direct ABHR (P = .001).

“survival and racing performance after surgical correction of rib fractures”
-seventy-three neonates underwent surgery for fractured ribs.
-Fifty- seven neonates (78%) survived to discharge from the hospital.
-Rib fractures were more commonly observed in colts and in the left hemithorax (61% and 57%, respectively).
-Sex, side affected, number of ribs fractured, co-morbidities, number of ribs repaired, and surgical technique did not affect the short- or long-term outcomes.
-Thirty-five of 57 (61%) foals treated surgically for rib fractures that survived to discharge started a race compared to 173 of 257 (67%) of maternal siblings that raced.

“loose bodies, cervical process joints”
-Surgery was performed on six APJs in five horses. Of the 14 LBs identified with CT, 13 were successfully removed from the C4/C5, C5/C6 and C6/C7 articulations.
-No surgical complications were encountered, and clinical signs of cervical dysfunction improved in all horses.
-All clinical cases returned to ridden work by 6 months post surgery.
-Histopathologic examination revealed the removed structures to be osteochondral or chondral loose bodies consisting of cartilaginous proliferation with or without ossification and central necrosis.

“beads”
-The GI TTT was shortened in the bit chewing group (median: 106.37 h, range: 70-171 h) compared to the no-bit group (median: 170.1 h, range: 149-186 h) at 80% bead passage
-Borborygmi (P = .8193), duodenal contractions (P = .2605), and 50% bead passage (P = .0781) showed no differences.

“suspensory size, plantar fasciotomy”
-The reliability of the ultrasonographic measurement of the PSL-CSA was excellent.
-Agreement between ultrasonographic assessment and MRI assessment of PSL-CSA was good.
-No difference was detected between preoperative (median, interquartile range; oblique-incidence, 2.07, 1.72-2.55; on-inci- dence, 2.23, 1.98-2.65) and postoperative (oblique-incidence, 2.08, 1.80-2.74; on-incidence, 2.28, 2.01-2.74) PSL-CSAs.

“lido/epi, median and ulnar nerve block”
VS=vector sum from lameness locator
-The reduction in the VS did not differ after nerve blocks with lido- caine/epinephrine or mepivacaine (P = .791).
-Mean time to VS <8.5 mm (n = 5) was 5 and 9.6 min for lidocaine/epinephrine and mepivacaine, respectively.
-For one horse, VS was not reduced to <8.5 mm with either treatment (this horse had the highest VS before treatments were administered).
-The decrease in VS to <8.5 mm lasted for 150 min in both treatment groups.

“parotid sialoadenectomy”
-removed salivary carcinoma
-Postoperative complications included right-sided facial nerve paralysis, difficulty with deglutition of fibrous feeds, and surgical site dehiscence.
-Wound healing was achieved by second intention. Partial improvement in nerve function was observed within the first 6 months. -At 12 months post- parotidectomy, no sign of tumor reoccurrence or metastatic disease was pre- sent, and the gelding returned to work.
Surgical Details:
-The lateral wall of the guttural pouch was excised with the mass and was reconstructed with a porcine small intestinal submucosal (SIS) sheet.
-Cisplatin beads were implanted in the wound bed prior to closure. Firocoxib (0.1 mg/kg orally, daily, every 24 h) treatment was initiated.
