Abstract

OBJECTIVE

To describe cryptorchidectomy performed with a paramedian or inguinal approach in domestic pigs and compare findings for commercial-breed pigs with those for pot-bellied pigs.

ANIMALS

47 client-owned (33 commercial-breed and 14 pot-bellied) pigs.

PROCEDURES

Medical records were searched to identify pigs that underwent surgical treatment for cryptorchidism from 2000 to 2018. Signalment, location of retained testes, surgeon, surgical approach, surgery time, anesthesia time, and postoperative complications were recorded. Complications were assessed with long-term follow-up. Age and surgical variables were compared between commercial-breed pigs and pot-bellied pigs.

RESULTS

Retained testes were most commonly located in the abdomen (27/47 [57%] left-sided, 15/47 [32%] right-sided, and 2/47 [4%] bilateral); 2 pigs each had 1 retained testis in the inguinal region, and 1 pig had 1 retained testis in the abdomen and 1 in the inguinal region. Forty-four pigs with abdominally retained testes were treated successfully with a paramedian surgical approach, including 3 for which an inguinal approach was attempted first. An inguinal approach was successful for 3 pigs with inguinally retained testes and 1 with an abdominally retained testis. Standard castration techniques were used for normally descended and inguinally retained testes. Long-term follow-up was available for 34 pigs; minor complications were reported for 3 (9%). Pot-bellied pigs were significantly older than commercial-breed pigs. No other intergroup differences were found.

CONCLUSIONS AND CLINICAL RELEVANCE

The paramedian surgical approach was successfully used for removal of abdominally retained testes in all pigs that underwent the procedure. The overall complication rate for cryptorchidectomy in the study sample was low.

SUMMARY

Sixteen horses were allotted to 4 groups of 4 horses each to evaluate the effect of tendon sheath lavage with 4 solutions (balanced electrolyte solution, 0.1% povidone-iodine, 0.5% povidone-iodine, and 0.5% chlorhexidine). The synovitis caused by 0.1% povidone-iodine lavage was not appreciably worse than that caused by balanced electrolyte solution lavage, but the 0.5% povidone-iodine and chlorhexidine lavages caused severe synovitis, and, therefore, should not be used for tendon sheath lavage.

Summary

During a 5-year period, renosplenic entrapment of the large colon was diagnosed in 57 horses referred to the Texas Veterinary Medical Center. The signalment of and clinical signs of disease in these horses were compared with such variables in 200 horses referred for other types of colic. Findings did not support a male gender predilection for this disease, as was previously reported. The case survival rate was 93% for this group of horses. Fourteen of the horses were treated nonsurgically by rolling them clockwise while they were under general anesthesia. Data supported the safety and efficacy of nonsurgical treatment.

Summary

From 1980 to 1989, 8 cesarean sections were performed on an elective basis in 5 mares. Four mares had partially obstructed pelvic canals; 2 of these mares had previously lost foals because of dystocia. Cervical adhesions that might obstruct passage of the fetus through the pelvic canal was suspected in the fifth mare. Cesarean section was performed prior to mares entering the first stage of labor. Readiness for birth was estimated by development of the mare's mammary gland and the presence of colostrum in the udder. A ventral midline celiotomy provided excellent exposure and healed without complications in all instances. Eight viable foals were produced. One foal developed bacterial pneumonia and septicemia after surgery and died. Follow-up evaluation of the 7 foals discharged from the hospital failed to reveal complications associated with elective cesarean section.

All mares survived the procedure. Fetal membranes were retained for up to 72 hours following surgery; however, systemic complications secondary to retained placenta did not develop. Three mares were bred subsequent to elective cesarean sections, with each mare conceiving the year following surgery. Three foals were produced by 1 mare and 2 foals have been produced by another mare by elective cesarean sections.
