Researchers have introduced a new method for the minimally invasive removal of non-cancerous tumors located in the difficult posterior head of the pancreas (on the right side of the abdomen, nestled in the curve of the duodenum, which is the first part of the small intestine). The technique, known as the retro-laparoscopic approach, enables surgeons to remove these tumors safely and effectively without taking out healthy pancreatic tissue, thus preserving organ function. Insulinomas are an abnormal tumor, usually benign, that develop in the beta cells of the pancreas. Insulinomas produce excess insulin, more than the body needs. They can cause a range of symptoms.The removal of benign tumors located in the challenging posterior head of the pancreas (right side of abdomen, nestled in the curve of the duodenum) can cause hypoglycemia, or low blood sugar. Symptoms of low blood sugar include confusion, sweating, weakness, and even coma. Surgery is currently the only treatment for patients with insulinoma, but it is often associated with a longer recovery time and the loss of healthy pancreatic tissue, which can lead to diabetes. The new study in the Annals of Surgical Oncology describes a new technique for minimally invasive removal of these tumors.The retro-laparoscopic approach, also known as the technique, enables surgeons to remove tumors from the pancreas without harming the healthy tissue, thus maintaining organ function. This is a significant discovery as it provides a less invasive and potentially safer way to remove pancreatic tumors, leading to fewer complications and better patient recovery. Furthermore, this technique may also lower the risk of diabetes and pancreatic insufficiency by preserving most of the pancreas tissue. Eduardo Vega, MD, who is the corresponding author and an assistant professor of surgery at Boston University, elaborates on the potential benefits of this approach.Chobanian & Avedisian School of Medicine.
Vega, along with Fernando Rotellar, MD, PhD, from Navarra University Clinic, Pamplona, Spain, conducted a laparoscopic retroperitoneal surgery on a 13mm insulinoma situated in the back of the pancreas. This involved using a camera and special tools through small incisions (10 to 5 mm) on one side of the patient’s abdomen to accurately locate and remove the tumor.
The researchers believe that the technique outlined in the study could have wider implications for the use of minimally invasive surgeries for other types of pancreatic tumors. “Thi rnrnThe research suggests exciting possibilities for the future of minimally invasive surgery and its use in complex anatomical scenarios. It could lead to further advancements in surgical techniques that may be beneficial for patients with different types of tumors and medical conditions. It may also enable retroperitoneal robotic approaches for pancreatic surgery in the future,” Vega said.
