For management of the afferent loop syndrome, surgical revision such as jejunojejunostomy or Roux-en-Y conversion is the established procedure. Percutaneous transhepatic catheter drainage was used as a method of palliative treatment of the obstructed afferent loop in a patient with extensive mesenteric and peritoneal dissemination of gastric cancer. There were no procedural-related complications, but severe bacterial cholangitis and septicemia occurred later. Our limited experience indicates that this procedure may be risky, and that an additional drainage catheter of the bile duct may be needed when biliary stasis is present.

Gianturco self-expanding metallic stents (GSs) were placed across an esophagojejunostomy which had become strictured secondary to recurrent anastomotic gastric cancer. Placement of the GS enabled the patient to take liquid food and swallow saliva, though only for a short period of time. One month after placement, the stented lumen restrictured with a markedly irregular contour. The patient's clinical status deteriorated with eventual occlusion of the stented anastomosis. The patient died of renal insufficiency 80 days after placement of the stent. There are some questions concerning the stability of applying the Gianturco-type bare stent to the digestive tract. In the future, more suitable stents will have to be developed.

We placed a Gianturco self-expanding metallic stent across the recurrent stricture of an esophagojejunostomy in a patient with gastric cancer. Though excellent passage of food resulted, intractable reflux occurred. Two months later the patient succumbed to recurrent tumor. At autopsy, the stent was patent and was partially covered by esophageal mucosa. There were narrow but deep ulcers around the stent hooks. The Gianturco metallic stent may provide an additional option for treating recurrent enteric strictures after other methods fail. Further refinements of the technique appear necessary.

Recent studies have revealed that endothelin-1 (ET-1) may be produced by human cancer cell lines and have suggested that in vivo the peptide might play a modulatory role in the growth of stromal cells surrounding tumor cells and/or in the growth of the cancer cells themselves, through paracrine or autocrine mechanisms. Therefore, we investigated whether ET-1 and ET receptors could be expressed in the human gastric cancer cell line HGT-1. By applying the reverse transcriptase polymerase chain reaction (RT-PCR) to total RNA extracted from the cells, using oligonucleotides synthesized from the sequence of the prepro-ET-1 mRNA, we have amplified a cDNA at the expected size (453 bp), which hybridized with a labeled ET-1-specific probe. In addition, RT-PCR was carried out to test whether HGT-1 cells expressed mRNA for ETA and/or ETB receptor subtypes. The amplified products of cDNA were at the size predicted for the ETA receptor (368 bp), whereas no ETB receptor mRNA could be detected.

To determine the operative outcome of coronary artery bypass graft surgery (CABG) for severe coronary artery disease in long-term hemodialysis patients, we analyzed a group of 16 patients who underwent CABG over a ten-year period in our institution. Hospital mortality was 12.5% (2 of 16 patients). These two patients died of ischemic colitis and perioperative myocardial infarction, respectively. There were five late deaths: one patient died from myocardial infarction, one from uremia, one from gastro-intestinal bleeding, one from gastric cancer and one from unknown cause. There were four significant postoperative complications (morbidity 25%), consisted of one pulmonary tuberculosis, one sternal dehiscence secondary to mediastinitis, one mediastinal hematoma secondary to late bleeding from the LITA dissection area and one A-V shunt trouble. Graft patency rate within the first two months was 93% (30 to 42 in 13 patients). Hospital survivors experienced complete relief from angina. Actuarial survival was 68.8% at 3 years, 57.3% at 5 years and 28.6% at 7 years. This rate is not significantly different from the survival of all dialysis patients, but seems to be better than that of dialysis patients with not operated coronary artery disease. We concluded that CABG in dialysis patients can be accomplished with acceptable morbidity and mortality and effective relief of symptoms.

A 51-year-old man suffered from bleeding esophageal varices. He had undergone partial gastrectomy for gastric cancer 1 year before. An extrahepatic arterioportal fistula and resultant portal hypertension were found. We successfully performed transarterial embolization of the fistula using stainless steel coils. Portal hypertension improved dramatically.

A 71-year-old man developed pyloric stenosis caused by gastric cancer. Vomiting and nausea resolved after the insertion of an uncovered Ultraflex stent (length 10 cm, inner diameter 18-23 mm) through a 7-cm-long stenosis, and the patient was able to eat a soft diet. After 6 weeks, stent occlusion occurred due to tumor ingrowth and accumulation of food residue. Endoscopic observation showed a very narrow residual lumen. A covered Ultraflex stent (length 10 cm, inner diameter 18-23 mm) was inserted through the first stent and expanded to its maximum diameter over the next 2 days. The patient's vomiting and nausea improved rapidly. He died 6 months after the second stenting procedure, from metastatic tumor spread, having remained free of nausea and vomiting. In this case, a covered metallic stent prevented tumor ingrowth and maintained gastrointestinal patency.

We present a patient with disseminated stomach cancer who presented with symptoms of acute obstruction of the splenic flexure of the colon caused by tumor spread. During a first attempt to insert a colon stent through the anus under endoscopic guidance as final palliative therapy, it was not possible to reach the region of the stricture, and iatrogenic perforation of the descending colon occurred, which resolved favorably under conservative management. A second attempt to insert a stent was made via percutaneous puncture of the transverse colon, approaching the region of the stricture by a descending route. The procedure was completed without complications and the patient's symptoms improved. Stent placement via percutaneous puncture of the colon has not previously been described in the literature. It may be an alternate route in cases of proximal strictures in which access through the anus has been unsuccessful even with the aid of endoscopic guidance.

A 38-year-old man, who had undergone surgery for gastric cancer one year previously, was found to have two pulmonary nodules (PNs: 10 mm in diameter) on chest radiography. Computed tomography (CT) revealed one of these nodules to be located near the B6b in the right lung hilus, while the other was located in the superficial region of the left lower lobe. Video-assisted thoracic surgery (VATS) was performed, for both diagnostic and therapeutic purposes. In this procedure, after preoperative CT-guided marking, simultaneous subsegmental resection of the right S6b and VATS wedge resection of the left lower lobe were performed successfully with adequate surgical margin. Histological diagnosis was compatible with metastatic pulmonary tumor from a gastric carcinoma primary. This case demonstrates that preoperative CT-guided localization can facilitate safe VATS subsegmental resection of a small deep pulmonary nodule.

We recently encountered a rare case where gastric cancer developed in the long-term postoperative stage after coronary artery bypass grafting (CABG) using the right gastroepiploic artery (RGEA) and distal partial gastrectomy was performed to treat the cancer. The patient was a 64-year-old man. In November 2001, he underwent three-vessel CABG, involving bypassing between the right coronary artery (RCA) and the RGEA, to treat an old myocardial infarction. In May 2003, he was admitted to our hospital because of exacerbation of diabetes mellitus and anemia. Gastric endoscopy revealed gastric cancer affecting the pylorus. Preoperative abdominal angiography showed the RGEA graft remained well patent. In June 2003, he underwent distal partial gastrectomy and regional lymph node dissection. Because the RGEA had been freed adequately to the point of bifurcation of the gastroduodenal artery during the previous CABG, the RGEA graft was preserved during distal partial gastrectomy. When the RGEA is used for CABG, it seems advisable to free the RGEA adequately to a point of bifurcation of the gastroduodenal artery. If done so, regional lymph node dissection around the RGEA is easier to perform when gastric cancer has occurred in these cases, eventually reducing the risk for injury of the graft. Following CABG with the RGEA, it seems essential to perform periodical checks for gastric cancer to facilitate early detection of gastric cancer. The necessity of close follow-up of these cases is endorsed by the fact that healing of gastric cancer by endoscopic mucosal resection (EMR) is highly probable if the cancer is detected at early stages.
