Splenic infarction following conventional open gastrectomy in patients with gastric malignancy: a CT-based study.

PURPOSE

The aim of this CT-based study was to investigate the frequency of splenic infarction (SI) following conventional open gastrectomy performed for gastric malignant neoplasms.

METHODS

20 patients who underwent subtotal or total gastrectomy, omentectomy, and D2 lymph node dissections preserving the spleen for gastric malignant neoplasms were retrospectively reviewed. Patients with postoperative CT scans within 3 months were enrolled in this study. CT imaging was performed with a 64-row multidetector CT scanner. Abdominal CT scan with precontrast and postcontrast portal phase images was performed on 19 of the patients, while pulmonary CT angiography was performed on 1 patient for chest pain. Second postoperative control abdominal CT images were also present for 3 of the 5 patients with SI. These examinations were also reviewed for the evolution of the SI's.

RESULTS

SI was detected in 5 of the patients (25%) at a postoperative early stage. A single infarct area was detected in 4 of the 5 patients while two distinct infarct areas were present in one patient. The infarct areas in two patients disappeared on the second postoperative control CT. A decrease in the size of the SI area in 1 patient was also detected on the second postoperative control CT scan.

CONCLUSION

The frequency of SI as a complication of abdominal surgeries tends to increase in CT-based studies. We have detected the highest frequency in the literature and suggest that SI, especially when accompanying D2 lymphadenectomy, should be included in the list of early stage gastrectomy complications.
