RESUMO

Conventional jejunal reconstruction procedures for large duodenal defects include jejunal serosal patch repair and duodenojejunostomy and have some risks of postoperative complications. The pedicled jejunal flap is used for reconstruction following laryngopharyngectomy, esophagectomy and other gastrointestinal surgeries. We report two cases of successful closure of duodenal defects after partial duodenectomies by pedicled jejunal flap reconstruction. Case 1: A 72-year-old man was diagnosed with gastrointestinal stromal tumor by esophagogastroduodenoscopy (EGD), endoscopic ultrasound-guided fine needle aspiration biopsy and computed tomography (CT). Case 2: A 63-year-old woman was diagnosed with early duodenal cancer using EGD and CT. Partial duodenectomy and pedicled jejunal flap reconstruction were performed in both patients. A part of the jejunum was formed into a pedicled flap to fit the duodenal defect and duodenojejunal anastomosis was performed. The patients did not report any postoperative gastrointestinal symptoms or abnormal findings during follow-up EGD or upper gastrointestinal radiography.

RESUMO

BACKGROUND Strangulation ileus is caused by external obstruction to the small bowel, which results in ischemia and loss of bowel peristalsis. Low-grade appendiceal mucinous neoplasm (LAMN) is a low-grade adenocarcinoma that arises in the appendix. LAMN is usually asymptomatic but can present with appendiceal rupture and pseudomyxoma peritonei (PMP). This report is of a rare presentation of LAMN with strangulation ileus in a 92-year-old man. CASE REPORT A 92-year-old man was admitted to the emergency room with sudden onset of lower abdominal pain and abdominal distension. Laboratory investigations showed a leukocytosis with a white blood cell (WBC) count of 14.6×10³/µL with 85.5% neutrophils, blood urea nitrogen (BUN) of 26.6 mg/dL, and serum creatinine of 2.6 mg/dL, consistent with acute renal failure. Arterial blood gas analysis showed lactic acidosis (pH of 7.11) with a base excess of -20.8 mmol/L and lactate of 13.7 mmol/L. Abdominal computed tomography (CT) showed ascites and a dilated obstructed closed loop of the distal ileum associated with an external mass (3.9×2.8 cm). An initial diagnosis was of strangulation ileus due to Meckel's diverticulum. Emergency ileocecal resection was performed. Histopathology showed a low-grade mucinous tumor arising from the mucosa of the appendix, consistent with LAMN. At a 13-month follow-up, the patient was well with no tumor recurrence. CONCLUSIONS This report is of a rare case of LAMN that presented as a surgical emergency with strangulation ileus.
