Since our first successful trial, spleen-preserving distal pancreatectomy with conservation of the splenic artery and vein for tumors of the pancreas and chronic pancreatitis has been performed more frequently. The technique for spleenpreserving distal pancreatectomy with conservation of the splenic artery and vein are outlined. The splenic vein is identified behind the pancreas and within the thin connective tissue membrane. The connective tissue membrane is cut longitudinally above the splenic vein. An important issue is to remove the splenic vein from the body of the pancreas toward the spleen, since a different approach may be very difficult. The pancreas is preferably removed from the splenic artery toward the head of the pancreas itself. This procedure is much easier than removing the pancreas from the vein side. One patient had undergone distal gastrectomy for duodenal ulcer, with reconstruction by Billroth Ⅱ tehcnique. If distal pancreatectomy with splenectomy had been performed for the lesion of the distal pancreas at the time, the residual stomach would also have to be resected. The potential damage done to the patient by reconstruction of the gastrointestinal tract in combination with distal pancreatectomy and splenectomy would have been much greater than with distal pancreatectomy only with preservation of the spleen and residual stomach. Benign lesions as well as low-grade malignancy of the body and tail of the pancreas may be a possible indication for this procedure.展开更多

METHODS: Pancreas and spleen involvement was retrospectively reviewed among 439 cases of resectable carcinoma of the gastric cardia, gastric corpus and total stomach. During gastric surgery, 2 ml of methylene blue was injected into the subserosal space of the gastric cardia or corpus to observe the spread of lymphatic flow in 54 cases of gastric carcinoma. The metastatic rate of LNs in splenic hillus and along the trunk of the splenic artery (No10, No11), postoperative complications and survival rates were investigated in 63 gastric carcinoma patients that had received gastrectomy with pancreas and spleen preservation (PSP). These were compared with the pancreas preservation (PP) group and pancreas and spleen combined resection (PSR) group. RESULTS: Among these 439 cases, only 25 cases were observed with direct invasion to the pancreas (5.7%), and 10 cases with direct invasion to the spleen (2.3%). After pathological examination of the pancreatic body and tail, we found 22 cases with pancreas and spleen combined resection, 4 cases (18.2%, 4/22) with direct invasion of the capsule and 2 with invasion to the superficial parenchyma (9.1%, 2/22), without metastasis to the lymph nodes within the pancreas and spleen. The metastatic rate of No10, No11 lymph nodes were 17.5% (11/63) and 19.1% (12/63) in the PSP group, 20.8% (45/216) and 25% (54/216) in the PP group, and 20% (6/30) and 23.3% (7/30) in the PSR group. There were no statistically significant differences (P > 0.05). Injection of methylene blue into the subserosal space of the stomach did not diffuse into the spleen or pancreatic parenchyma. Postoperative complications, diabetes and mortality in PSP (0%, 0%, 0%) were lower than in PP (4.2%, 0.9%, 0.9%) or PSR (40%, 10%, 3.3%). The 5-year survival rate (5-YSR) and 10-YSR in PSP (57.5%, 52.0%) were higher than in PSR (37.5%, 30.0%). Those patients with stage II and III(a) treated by PSP, improved markedly. CONCLUSIONS: The surgical procedure of pancreas and spleen preservation for gastric cancer is a safe and organ function protected method. Postoperative complications were lower and survival rates were higher, the radicality was not reduced. These results indicate that PSP is preferred in patients with gastric carcinoma of stage II or III(a).展开更多
