Finding carcinoid tumor before bariatric surgery. Is preoperative endoscopy necessary? Case report

Menetrier's disease in a morbid obese patient undergoing bariatric surgery: A case report

Introduction and importance

Menetrier's disease is a rare type of hypertrophic gastropathy characterized by the atrophy of the gastric parietal cells and dilatation of mucus releasing glands. Hereby, we present a morbid obese patient who has undergone laparoscopic sleeve gastrectomy (LSG) and he has also diagnosed with Menetrier's disease.

Case presentation

A 67-year-old male patient whose body mass index (BMI) was 39 kg/m². Preoperative endoscopy was done. There were no pathologies except increased gastric mucosal folds. LSG was done. During the surgery it was noticed that gastric tissue was abnormally thick. After LSG completed, it was observed that there was an abnormal bleeding from the staple line. The staple line was oversewed with 3.0 V-Loc™ and bleeding was stopped. Pathology report was compatible with menetrier's disease.

Clinical discussion

Hypoalbuminemia and H. pylori take an important place in diagnosis of Menetrier's disease, but H. pylori was not detected and albumin level was normal in our patient. For certain diagnosis full-thickness gastric biopsy is needed. The routine use of preoperative endoscopy in patients scheduled for bariatric surgery was still controversial until recently.

Conclusion

This is the first case with menetrier's disease that has undergone LSG. Preoperative endoscopic evaluation before bariatric surgery is crucial. As in this case, it will be effective in terms performing additional intraoperative precautions when necessary and preventing possible complications.

Incidental finding after laparoscopic gastric sleeve, the value of pathology

Gastric neuroendocrine tumors (NET) are rare tumors with a broad spectrum of symptoms; in recent years, the number of cases has increased due to the growing number of upper endoscopies. Obesity has become a worldwide epidemic and bariatric surgery one of the most effective therapies to control this illness. As more surgeries are performed, the number of histopathological samples will also increase. Incidental discoveries on these histopathological specimens are difficult situations to encounter as medical plans, prognosis and therapy will have to change accordingly. We present the case of a 43-year-old patient who underwent a laparoscopic gastric sleeve. On pathology, a NET was detected, and additional surgery was required. On follow-ups, the patient is doing well.
