AI Article Synopsis
- This study details a successful laparoscopic vasectomy technique performed on 14 African elephants, focusing on their anesthesia and surgical methods in a field setting.
- The procedure involved removing a segment of the ductus deferens while keeping the elephants in a modified standing position, and their recovery showed no significant behavioral issues.
- Despite some surgical complications in a few elephants, overall results indicate that laparoscopic vasectomy can be safely performed in free-ranging elephants.
Article Abstract
Objective: To describe a surgical technique for, and outcome after, laparoscopic vasectomy of free-ranging elephants.
Study Design: Case series.
Animals: African elephants (Loxodonta africana; n = 14).
Methods: Male elephants (12-35 years old) were anesthetized with etorphine and supported in a sling in a modified standing position, and positive pressure ventilated with oxygen. Anesthesia was maintained with IV etorphine. Vasectomy was performed under field conditions by bilateral, open-approach, flank laparoscopy with the abdomen insufflated with filtered ambient air. A 4-cm segment of each ductus deferens was excised. Behavior and incision healing were recorded for 8 months postoperatively.
Results: Successful bilateral vasectomy (surgical time, 57-125 minutes) was confirmed by histologic examination of excised tissue. Recovery was uneventful without signs of abnormal behavior. Large intestine lacerations (3 elephants; 1 full and 2 partial thickness) were sutured extracorporeally. One elephant found dead at 6 weeks, had no prior abnormal signs. Skin incisions healed without complication.
Conclusions: Laparoscopic vasectomy can be performed in African elephants in their natural environment.

Article Synopsis
- Vasectomy is a common family planning procedure, typically done through a scrotal method, but laparoscopic vasectomy is less common and may have advantages in reducing risks and costs during concurrent surgeries like hernia repair.
- A scoping review analyzed six peer-reviewed studies focusing on laparoscopic vasectomy, primarily involving patients who needed surgery for conditions like inguinal hernia in the 1990s and early 2000s, with no recorded complications.
- The review indicates that synchronous laparoscopic vasectomy can enhance surgical efficiency by reducing anaesthetic and operative times, but also acknowledges the limitations and lack of extensive evidence on its safety and effectiveness due to the few cases available in the literature.

Article Synopsis
- Duplication of the vas deferens is a rare condition often found during surgeries like inguinal hernia repair and vasectomy.
- Proper identification of this condition during surgery is essential to prevent damage and complications.
- The text reports a specific case involving a patient with both duplicated vas deferens and an incarcerated urinary bladder during a laparoscopic surgery.

Vasectomy damage is a common complication of open nonmesh hernia repair. This study was a retrospective analysis of the characteristics and possible causes of vas deferens injuries in patients exhibiting unilateral or bilateral vasal obstruction caused by open nonmesh inguinal herniorrhaphy. The site of the obstructed vas deferens was intraoperatively confirmed.
