Silastic band erosion in the bypassed stomach after Fobi-Pouch operation for obesity: Case report

Abstract Introduction Worldwide, one of the most commonly performed bariatric surgeries is the laparoscopic Roux-en-Y gastric bypass (LRYGP). Access to the bypassed stomach in patients who have undergone this procedure, for evaluation and/or management in different clinical situations remains a challenge for the physician. In order to facilitate the entrance to the gastric remnant, a silastic marker is left in place during the Fobi-Pouch operation, a modified laparoscopic gastric bypass surgery technique. Presentation of case We present the case of a 56-year old female who presented 10 years after a Fobi-pouch operation, complaining of severe upper gastrointestinal bleeding. An enteroscopy revealed several marginal ulcers and erosion of the silastic ring marker in the excluded stomach. A partial gastric sleeve resection including the silastic ring was performed without any complications, preventing further bleeding due to the eroded ring. Discussion Physicians must be familiarized with the different bariatric procedures in order to associate the patient’s symptomatology and possible surgery-related complications. Gastric ulceration and bleeding related to the presence of a foreign body have been previously described; however, to the best of our knowledge this is the first article reporting the concomitant erosion and bleeding of the silastic marker in the excluded stomach. Conclusion Silastic marker erosion in the bypassed stomach is a rare but possible complication not reported in the literature before. Different approaches for this complication are possible including laparoscopic management, with excellent results.
