Single Port Laparoscopic Gastrostomy: description of a technique and initial experience.

Introduction: Since the first classic descriptions of surgical gastrostomies for feeding by supra-umbilical medial incisions, patients were operated under general anesthesia, with prolonged time of surgery; these were patients in poor health status, undernourished due to inadequate intake or to neurological or tumor involvement, with prolonged hospitalization, both for the recovery of the intestinal motility as well as for the recovery of post-surgical wounds. Therefore, we describe a new minimally invasive technique as an alternative to the percutaneous or endoscopic gastrostomy, in patients where we are not allowed to place a nasogastric tube to insufflate the stomach. This is mostly seen in patients with tumors, which cause obstruction.

Material and methods: Between July 2012 and June 2013, 8 patients underwent a single port laparoscopic gastrostomy. Five were females, mean age: 77 years (range: 67-87). In all the patients, it was impossible to place a nasogastric tube, due to obstructive tumor.

Results: The mean time of the procedure was 45 minutes. Seven patients underwent tolerance of dextrose 10% through the catheter after 12 hours and one 24 hours after the procedures. Enteral feeding was indicated after the dextrose 10% tolerance was performed. No complications related to the procedure were observed.

Discussion: Currently, the gold standard technique to perform a gastrostomy is the percutaneous or endoscopic approach. In patients with head and neck tumors, when it is not possible to insert a nasogastric tube to insufflate the stomach, a laparoscopic gastrostomy would be indicated. We describe a new technique, step by step, to perform less invasive laparoscopic surgery by a single port laparoscopic gastrostomy.

Conclusion: The diameter created is the same as the one performed with an open technique, but in this case, with a minimally invasive approach, that allows us to start feeding the patient with a high quality of feeding, because of the wider lumen.
