OBJECTIVE
The aim of this work is to consider the mechanical complications of jejunoileal bypass for morbid obesity which can have a serious outcome because of the occult nature of the symptoms.
METHODS
The mechanical complications of jejunoileal bypass are mainly intussusception of the bypassed ileal segment, internal herniation of the ileal loops through the mesenteric defects and laparocele.
METHODS
A recent case is reported in which, most unusually, intussusception and volvulus were both present, with ischaemia and necrosis of the bypassed segment. Moreover, the general health of the patient remains normal despite the severity of the complication.
METHODS
Examination of blind loop with CT scan which showed an abdominal mass of uncertain interpretation.
METHODS
A laparotomy revealed a volvulus of bypassed ileal loops, probably caused by a simultaneous ileal intussusception and an adhesion. On account of the extensive nature of the process and the degree of advanced ischaemia and gangrene patches in the folds of the ileum, resection of the entire bypassed segment as far as the previous jejunoileal anastomosis was necessary.
CONCLUSIONS
The authors point out the occult nature of the manifestations of this type of complication: aspecific abdominal pains in all quadrants, fever, non vomiting, normal passing of faeces and gas and suggested that simultaneous diverticulitis of the colon (frequently found in the obese) can further complicate and delay diagnosis.
