Successful new treatment for intractable cervical esophageal stenosis of a jejunal segment transpositioned with a vascular anastomosis: report of a case.

Strictures of the alimentary tract are conventionally treated by fluoroscopically guided bouginage and endoscopic balloon dilation, which is often very effective. However, severe and recurrent stenosis associated with ischemic injury in a jejunal segment transpositioned with a vascular anastomosis after reconstruction for cervical esophageal cancer is an intractable problem. We describe a new method using a Steno-Cutter to successfully treat a patient with this type of stricture following surgery for cervical esophageal cancer. The positive results achieved in this case suggest that our new method could represent a promising option of treatment for strictures when conventional modalities fail.

BGP expression in gastric biopsies may predict the development of new lesions after local treatment for early gastric cancer.

BACKGROUND: Our previous studies have demonstrated the significant role of the generative cells of intestinal metaplasia (IM) expressing brain (fetal)-type glycogen phosphorylase (BGP) (BGP-IM) as a premalignant lesion of intestinal-type adenocarcinoma. The aims of the present study were to investigate the incidence of BGP-IM in gastric biopsy specimens and to establish BGP-IM as a predictor of the coexistence of accessory carcinoma and/or metachronous cancers before and after local treatment for early gastric carcinoma. METHODS: We studied the incidence of BGP-IM in eight endoscopic biopsy specimens of methylene blue-positive mucosa of the stomach obtained from patients with multiple gastric carcinomas (n = 14), a single carcinoma (n = 25), and atrophic gastritis (n = 20). RESULTS: BGP positivity was 93.3% in the multiple carcinomas and 80.0% in the single carcinomas. The incidences of BGP-IM (mean percentage +/- SD) in the stomachs with multiple carcinomas, single carcinoma, and atrophic gastritis were 83.2% +/- 22.8%, 36.5% +/- 41.3%, and 7.1% +/- 18.0%, respectively. The incidence was significantly higher in the stomachs with multiple carcinomas than in those with a single carcinoma or those with atrophic gastritis (P < 0.001). CONCLUSION: It is suggested that the frequent appearance of BGP-IM reflects the high potential of carcinogenesis of intestinal-type gastric cancer, and that the involvement of BGP-IM in more than 50% of the eight biopsies may be a predictor of the coexistence of accessory and/or metachronous carcinoma before and after local treatment for early gastric carcinoma.

Extensive intraoperative peritoneal lavage and chemotherapy for gastric cancer patients with peritoneal free cancer cells.

The effects of extensive intraoperative peritoneal lavage (EIPL) for gastric cancer patients with peritoneal free cancer cells were investigated. This study was based on 22 consecutive patients with peritoneal free cancer cells, among 663 patients who underwent curative surgical treatment for advanced gastric cancer. The 22 patients were followed up for 2 years or until death. These patients were divided into three groups: group 1, patients with no additional intraoperative therapy (from 1989 to 1992; n = 8); group 2, patients with intraoperative intraperitoneal chemotherapy alone (from 1992 to 1995; n = 7); and group 3, patients with EIPL followed by intraoperative intraperitoneal chemotherapy (from 1996 to 1999; n = 7). Reverse transcriptase-polymerase chain reaction (RT-PCR) analysis showed that viable cancer cells were not detected after the eighth EIPL in a gastric cancer patient with numerous intraperitoneal free cancer cells. In group 3, 4 of the 7 patients survived for more than 2 years, including 3 with cancer-free status, whereas no patient survived cancer-free in groups 1 and 2. The peritoneal recurrence rates and cancer-specific 2-year survival rates in groups 1, 2, and 3 were 100%, 85.7% and 42.9%; and 0%, 14.3%, and 57.1%, respectively. The 2-year survival rate of group 3 was significantly higher than that of group 1 (P = 0.017) and that of group 2 (P = 0.025). In a subset analysis, patients with peritoneal free gastric cancer cells but no macroscopic dissemination showed a statistically significant improvement in survival those treated with EIPL compared with those not treated with EIPL.
