Protein-losing enteropathy secondary to nonocclusive mesenteric ischemia: A case report.

Abstract：

RATIONALE:Nonocclusive mesenteric ischemia (NOMI) is a life-threatening disorder; prompt diagnosis is vital. Surgical treatment is often required, but some cases can be treated conservatively. We herein report an extremely rare case wherein protein-losing enteropathy (PLE) developed after conservative treatment of NOMI. PATIENT CONCERNS:The patient was a 66-year-old man. He underwent laparoscopic super low anterior resection and temporary ileostomy for sigmoid colon cancer and rectum cancer. During the postoperative course, he developed ileus. Subsequently, he developed shock. On examination, the possibility of NOMI could not be denied, but intestinal necrosis was absent. Conservative treatment was initiated. His general condition improved, but the ileus persisted. Therefore, we performed a stoma closure. Ten days after stoma closure, he developed continuous unexplained diarrhea. The serum albumin and total protein levels were low. The symptoms improved after administration of an antidiarrheal drug, but the root cause was yet untreated. DIAGNOSIS:The patient's alpha-1 antitrypsin clearance was increased. A CT scan revealed an enhanced hypertrophied wall of the short segment of the small intestine, and 99m Tc-labeled human serum albumin scintigraphy revealed protein leakage into the thickened wall of the small intestine. We arrived at a definitive diagnosis of PLE secondary to NOMI. INTERVENTIONS:Partial resection of the affected small intestine was performed. OUTCOMES:The patient recovered uneventfully and was discharged on the 30th postoperative day. LESSONS:NOMI has a high mortality rate, often requiring intestinal resection immediately after onset. To our knowledge, there is no report of PLE developing after conservative treatment, as in our case. Further study of cases is necessary to determine the reversibility of the condition, which will influence the therapeutic plan. We herein present an extremely rare case of PLE after conservative treatment for NOMI. The possibility of PLE also needs to be considered when hypoalbuminemia occurs after conservative treatment of NOMI.
