[Preventive gastrectomies before kidney transplantations]

Area of Science:

• Nephrology
• Gastroenterology
• Surgical Oncology

Background:

• Gastroduodenal bleeding or perforation is a serious complication in renal transplant patients, with high mortality rates.
• Identifying patients at risk for gastroduodenal complications is crucial for effective management.
• Chronic hemodialysis patients awaiting renal transplantation represent a population where prophylactic measures may be beneficial.

Purpose of the Study:

• To evaluate the safety and efficacy of prophylactic gastric surgery in renal transplant candidates with identified gastroduodenal risk factors.
• To assess the outcomes of different surgical procedures in managing high-risk and low-risk patients.

Main Methods:

• A retrospective review of 61 patients undergoing chronic hemodialysis and preparation for renal transplantation since 1974.
• Identification of gastroduodenal risk factors including history, ulcer disease, or hyperchlorhydria.
• Surgical intervention in 20 patients with identified risk factors, categorized into high-risk (selective gastric vagotomy + hemigastrectomy) and low-risk (selective proximal vagotomy or truncal vagotomy + drainage) groups.

Main Results:

• No serious postoperative complications were observed in patients who underwent prophylactic gastric surgery.
• No mortality was recorded in the surgically treated group.
• The study included 12 high-risk and 8 low-risk patients who received specific surgical interventions.

Conclusions:

• Prophylactic gastric surgery appears to be a safe and effective strategy in renal transplant candidates with gastroduodenal risk factors.
• This surgical approach may mitigate the risk of severe gastroduodenal complications and associated mortality in this vulnerable patient population.
• Further research could explore long-term outcomes and cost-effectiveness of this prophylactic measure.
