Closure of Mesenteric Defects in Laparoscopic Roux-en-Y Gastric Bypass in order to prevent Internal Hernias

Small bowel obstruction due to internal hernia is the most common and potentially serious complication after laparoscopic Roux-en-Y gastric bypass [1,2,6,7].

Complete closure of mesenteric defects in laparoscopic Roux-en-Y gastric bypass results in a significant reduction in internal mesenteric hernias [3,5,7].

The reported risk of complication caused by closure of the mesenteric defects is low [4,7]. Primary closure of mesenteric defects can be performed safely and should be viewed as a routine part of that operation [2,7].

 

 

    Symptoms of internal hernia:

    • Vague colic pain
    • Mostly pain in left abdomen
    • Intermittant character

    Incidence of internal hernia [7]:

    • Non-closure: 11,7%
    • Closure: 2,5%

    In 2010, a new and simplified technique of closing the mesenteric defects was introduced using a stapler device [9]. Two aspects to consider with regards to the closure of the mesenteric defects is time consumption and ease of use [7]. Suturing may also entail increased risk for mesenteric hematomas and anatomical disturbances causing secondary kinking and bowel obstruction [2,4].Closing the mesenteric defects with a stapler device is technically unchallenging and adds only 4 minutes to the total operating time and can be applied in all patients without affecting complication rate [7].Please review the images below on how the EHMS of Novisurge can be used to close Petersen’s space and the jejunal mesenteric defect after laparoscopic Roux-en-Y gastric bypass to prevent internal hernias.

    On average a bariatric or metabolic surgeon will require 14-16 staples of the EHMS to close both mesenteric defects with a double-layer. Given the fact that the EHMS is preloaded with 20 titanium staples enables the bariatric or metabolic surgeon to close both defects without any instrument exchange and/or disruption of the surgical flow.

    MiniMIZER Gastric RING

    In banded gastric bypass and banded gastric sleeve a non-adjustable gastric ring should be used which should be easy to place. more
