  • Jejuno-Jejunal Intussusception after Roux-en-Y Gastric Bypass
    Obesity Surgery, 2020
    Co-Authors: Chys Brecht, Fierens Johan, Sohier Stefan, Van Krunckelsven Ludo, Dedrye Lieven
    Abstract:

    Introduction Roux-en-Y gastric bypass is the most common bariatric procedure in Belgium. Retrograde Intussusception is identified as a rare late complication. Methods Here we present two cases of retrograde jejuno-Jejunal Intussusception after Roux-en-Y gastric bypass. Results Women who experienced excellent weight loss appear most prone. Although ectopic pacemaking is suggested, the exact pathophysiologic mechanism remains unclear. Simple manual reduction seems to be insufficient as treatment. Lowest recurrence rates are noted after segmentectomy. Conclusion Retrograde Intussusception is a rare late complication after RYGB which is becoming more and more relevant due to increasing procedure volumes. Retrograde peristalsis by ectopic pacemakers could be identified as a cause. Segmentectomy appears to be the best treatment of choice.

  • Recurrent adult jejuno-Jejunal Intussusception due to inflammatory fibroid polyp – Vanek’s tumour: a case report
    Diagnostic Pathology, 2014
    Co-Authors: Kenneth M Joyce, Peadar S. Waters, Ronan Waldron, Iqbal Khan, Zolt S Orosz, Tamas Nemeth, Kevin Barry
    Abstract:

    Background: Adult Intussusception is a rare but challenging condition. Preoperative diagnosis is frequently missed or delayed because of nonspecific or sub-acute symptoms. Case presentation: We present the case of a sixty-two year old gentleman who initially presented with pseudo-obstruction. Computerised tomography displayed a jejuno-Jejunal Intussusception, which was treated by primary laparoscopic reduction. The patient re-presented with acute small bowel obstruction two weeks later. He underwent a laparotomy showing recurrent Intussusception and required a small bowel resection with primary anastomosis. Histological examination of the specimen revealed that the Intussusception lead point was due to an inflammatory fibroid polyp (Vanek’s tumour) causing double invagination. Conclusions: Adult Intussusception presents with a variety of acute, intermittent, and chronic symptoms, thus making its preoperative diagnosis difficult. Although computed tomography is useful in confirming an anatomical abnormality, final diagnosis requires histopathological analysis. Vanek’s tumours arising within the small bowel rarely present with obstruction or Intussusception. The optimal surgical management of adult small bowel Intussusception varies between reduction and resection. Reduction can be attempted in small bowel Intussusceptions provided that the segment involved is viable and malignancy is not suspected.
