ZAMARIN M, Jaime; COURT R, Ismael; BRAVO L, Jorge  y  CONTRERAS P, Juan Eduardo. Petersen's space hernia: late complication of laparoscopic gastric bypass. Rev Chil Cir [online]. 2014, vol.66, n.6, pp.536-542. ISSN 0718-4026.  http://dx.doi.org/10.4067/S0718-40262014000600005.

Introduction: Petersen's Space Hernia is a protrusion of intestinal loops through a defect between the alimentary loop and the transverse mesocolon that occur as a late complication of Gastric Bypass. Objective: To present our experience in the management of this entity, making emphasis on the difficulty of clinical diagnosis, the typical CT Scan findings and to suggest prevention and management strategies. Method: Case series study of patients with Petersen's Space Hernia after Laparoscopic Gastric Bypass. Clinical presentation, CT Scan findings and surgical results were analyzed. Results: 8 patients. Mean age 43 years. All presented al least 12 months after primary surgery, with unspecific abdominal pain. CT Scan most frequent findings were: Swirled mesentery, engorgement of mesentery vessels and the mushroom sign. Surgery was performed laparoscopically in the 8 patients. No bowel ischemia was found. In all cases, once reduced the protruded loops, complete closure of the defect with a running non absorbable suture was done. Conclusion: In patients with Gastric Bypass, presenting with abdominal pain, a high degree of suspicion must be kept about this entity. Clinical findings are unspecific and radiological study is crucial. When diagnosed on time bowel necrosis is avoided and the main surgical goal is to achieve a complete closure of the defect with non absorbable suture.
