Surgical management of patients with bowel obstructions secondary to gastric cancer

Figure 1 The treatment decision-making process. PET/CT: Positron emission tomography/computed tomography; SBO: Small-bowel obstruction.

Figure 2 Patients who had had gastric cancer resection underwent positron emission tomography/computed tomography because of small-bowel obstruction. A: A 68-year-men who had had gastric cancer resection 2 years previously underwent positron emission tomography (PET)/computed tomography because of small-bowel obstruction. Whole body PET projection image and axial PET image showed no focal hypermetabolic activity; B: A 38-year-female who had had gastric cancer resection 1 years previously underwent positron emission tomography/computed tomography because of small-bowel obstruction. Whole body PET projection image and axial PET image showed the remnant stomach (white arrow) and lymph-node (black arrow) focal hypermetabolic activity.

Figure 3 1-year survival curves. A: With respect to no tumor recurrence and tumor recurrence group in positron emission tomography/computed tomography. There was significant difference between two subgroups (P = 0.00). The 1-year survival rate in positron emission tomography/computed tomography (PET/CT) tumor recurrence group is 8.8%, while 93.5% in no tumor recurrence group; B: With respect to exploratory laparotomy and nonoperative treatment group. There was no difference in 1-year survival based on type of surgical vs nonsurgical management (P = 0.72); C: With respect to tumor recurrence group in positron emission tomography/computed tomography. The 1-year survival rates for patients in each subgroup were, respectively, 0.0% for tumor nonoperative treatment, and 20% for exploratory laparotomy group. There is also no significant difference between two subgroups (P = 0.71).
