Abstract
Sclerosing encapsulating peritonitis (SEP) is a rare clinical condition characterized by the formation of a thick, fibrous membrane encasing the intestines, which may lead to intestinal obstruction. The pathogenesis is not completely understood, but various risk factors are well established. However, there are only few reported cases of SEP associated with peritoneal carcinomatosis. Herein, we report a case of a 69-year-old male patient who presented clinically with acute intestinal obstruction 2 years after undergoing a resection procedure for gastric cancer. An abdominal computed tomography revealed findings typical of SEP. Consequently, the patient underwent exploratory laparoscopy, which confirmed the diagnosis of SEP and established the etiology as peritoneal metastases. The patient was managed conservatively, and his symptoms showed some improvement. The patient was at an advanced stage of the disease, and thus remained on palliative care and passed away 1 month later. Although very rare, physicians should consider SEP in their differential diagnoses of intestinal obstruction in patients, particularly in those with a history of intra-abdominal malignancies.
