Advanced gastric cancer Borrmann type IV can be difficult to find. It is especially true after subtotal gastrectomy. Remnant stomach is difficult to see clearly. Mucosa of the remnant stomach is usually edematous, and covered with bile-tinged fluid. Subtle mucosal changes, which are critical for the diagnosis of Borrmann type IV, cannot be noticed in this setting. As a result, Borrmann type IV of the remnant stomach is usually found in far advanced stages. Curative resection is possible only in very selected cases.

In this lady, subtle ill-defined erosive lesion was found in the lesser curvature side of the remnant stomach, and the biopsy was signet ring cell carcinoma. Surgery was done, and the tumor was 11cm in diameter. Most of the remnant stomach was infiltrated by undifferentiated-type of gastric cancer.

(2015, F/60)
Left: AGC, signet ring cell carcinoma, T2N0 (proper muscle invasion)
Middle: There was no evidence of recurrence in the follow up endoscopy after surgery ( 1 year before final diagnosis of remnant gastric cancer)
Right: Remnant gastric cancer, Borrmann type IV, poorly cohesive differentiated, 11x8cm

It has been reported that RGC has unique patterns of lymph node metastasis compared with PPGC. In PPGC, the main lymphatic flow drains to the lymph nodes along the celiac artery through the lymph nodes at the lesser curvature, the left gastric artery, and the right side of the cardia. In RGC, it has been considered that the characteristics of lymph node metastases are different from PPGC because abnormal lymphatic formation is induced as a result of cutting off these lymphatic pathways at the initial surgery. Furthermore, Tokunaga et al mentioned that altered lymphatic drainage after DG may affect the long-term survival of RGC patients with advanced stage disease. Previous studies have investigated the incidence of lymph node metastasis focusing on around the splenic artery, in the splenic hilum, at the lower mediastinum, and in the jejunal mesentery. Some authors demonstrated a higher incidence of lymph node metastasis around the splenic artery, in the splenic hilum, and at the lower mediastinum in RGC; therefore, lymphadenectomy of these regions is recommended for curative surgery. In patients with previous B-II reconstruction, the rate of lymph node metastases in the jejunal mesentery has been reported to be 10.0%-67%. Thorban et al reported that RGC patients with lymph node metastases in the jejunal mesentery had a poor prognosis, with a median survival time (MST) of 13.2 mo. Similarly, Leo et al reported that RGC patients with lymph node metastases in the jejunal mesentery had worse outcomes than those with metastases in other lymph node stations. Therefore, jejunal mesentery lymph node dissection including the origins of each involved jejunal artery is recommended for RGC patients with previous B-II reconstruction. However, the details of the spread of lymph node metastases in RGC patients are still uncertain, because the number of patients examined in these studies was too small. (Ohira. WJG 2016)

The mean interval between previous gastrectomy and diagnosis of remnant primary gastric cancer was 18.8 years for patients who had undergone their first gastrectomy for malignant disease (n = 13) and 28.6 years for patients with benign disease (n = 25). Patients with remnant primary gastric cancer showed a greater male predominance compared with patients having upper one-third cancer (92.1% vs 65.5%, respectively, P = .001). Patient distribution according to operative curability, tumor size, stage, and histology showed no significant differences between the 2 groups. Overall 5-year survival rates of patients with remnant primary gastric cancer and those with upper one-third cancer were 53.7% and 62.9% (P = .346), respectively. Differences in the 5-year survival rates at each stage between the groups were not statistically significant.

Results: Two-thirds of the lesions were located on the body, and half were located on the suture line. En bloc resection, R0 resection, and en bloc with R0 resection rates were 88.9%, 100%, and 88.9%, respectively. Curative resection rate for EGC was 91.7%. Perforation occurred in one patient (5.6%) and was successfully managed by endoscopic closure with metallic clips and conservative management. There was no significant bleeding after ESD. During a median follow-up of 47.5 months, no local, metachronous, or extragastric recurrence was seen for either EGC or adenoma lesions.

(B) Chromoendoscopy with indigo carmine dye. (C) Dissection of the submucosal layer after circumferential incision of the mucosa. Staples (arrowhead) and severe fibrosis are observed around the suture line. (D) The tumor is completely removed by en bloc resection.
