Internal Hernia After Laparoscopic Gastric Bypass

2014-08-27 03:13:10 | BioPortfolio


To see if closing the mesenteric defects created at a Laparoscopic Gastric Bypass is better than leaving them open.


When the patients who has undergone a Laparoscopic Gastric Bypass lose weight, the mesenteric defects that are inevitable to cause, gets bigger and can cause an internal hernia (IH). This study will observe whether it is better to close the defects or leave them open. The patients will be randomized into two groups. One, where the defects are closed with sutures and one where the defects are left alone. The primary endpoint of the study is the prevalence of surgery for obstruction. Information about this will be gathered through the national register for obesity surgery in Sweden, SOReg. Each arm in the study will include 1200 patients and the follow up period will be three years. Since the register mentioned above is an ongoing register, the results can be studied over a longer period if wanted. The national hospital registry will further improve the follow-up.

Medical and Biotech [MESH] Definitions

DUODENAL OBSTRUCTION by the superior mesenteric artery (MESENTERIC ARTERY, SUPERIOR) which travels in the root of the MESENTERY and crosses over the DUODENUM. The syndrome is characterized by the dilated proximal duodenum and STOMACH, bloating, ABDOMINAL CRAMPS, and VOMITING. Often it is observed in patient with body casts after spinal surgery.

Ischemic tissue injury produced by insufficient perfusion of intestinal tissue by the MESENTERIC CIRCULATION (i.e., CELIAC ARTERY; SUPERIOR MESENTERIC ARTERY; INFERERIOR MESENTERIC ARTERY; and MESENTERIC VEINS). It can progress from ISCHEMIA; EDEMA; and GANGRENE of the bowel wall to PERITONITIS and cardiovascular collapse.

Functional obstruction of the COLON leading to MEGACOLON in the absence of obvious COLONIC DISEASES or mechanical obstruction. When this condition is acquired, acute, and coexisting with another medical condition (trauma, surgery, serious injuries or illness, or medication), it is called Ogilvie's syndrome.

Occlusion of the outflow tract in either the LEFT VENTRICLE or the RIGHT VENTRICLE of the heart. This may result from CONGENITAL HEART DEFECTS, predisposing heart diseases, complications of surgery, or HEART NEOPLASMS.

Endoscopic examination, therapy or surgery of the gastrointestinal tract.
