From the Research
During laparoscopic oophorectomy in a patient with a previous hernia repair, the umbilical port should be placed away from and not through the previous hernia repair site. This approach minimizes the risk of damaging the mesh or compromising the integrity of the previous repair. Alternative port placement options include using a left upper quadrant (Palmer's point) entry or selecting a site lateral to the previous repair. When planning port placement, surgeons should carefully review previous operative reports and consider preoperative imaging to identify the exact location and extent of the mesh. The concern with placing a port through a previous hernia repair site is twofold: it may damage the prosthetic mesh material, potentially leading to hernia recurrence, and it could create difficulties with obtaining adequate pneumoperitoneum due to air leakage around the port. Additionally, scar tissue at the repair site may increase the risk of visceral or vascular injury during trocar insertion. If absolutely necessary to place a port near a previous repair site, using an open (Hasson) technique rather than a blind Veress needle insertion is recommended to minimize these risks.
The most recent and highest quality study, 1, which reported on the outcomes of laparoscopic-assisted, open umbilical hernia repair, did not directly address the question of port placement during laparoscopic oophorectomy. However, it highlighted the importance of careful planning and technique in hernia repair to minimize complications. Another study, 2, which compared laparoscopic and open umbilical hernia repair, found that laparoscopic repair was associated with a lower risk of wound infection, wound dehiscence, and recurrence. While these studies do not provide direct evidence for port placement, they emphasize the need for careful consideration of the previous hernia repair site during laparoscopic procedures.
Key considerations for port placement include:
- Avoiding damage to the mesh or compromising the integrity of the previous repair
- Minimizing the risk of hernia recurrence
- Preventing difficulties with obtaining adequate pneumoperitoneum
- Reducing the risk of visceral or vascular injury during trocar insertion
- Using alternative port placement options, such as the left upper quadrant (Palmer's point) entry or a site lateral to the previous repair.
In the absence of direct evidence, the recommendation is based on the principles of minimizing risk and ensuring the integrity of the previous repair, as supported by studies such as 3, which highlighted the importance of careful technique in laparoscopic surgery to avoid complications.
