Abdominal pain usually originates from the abdomen, but the lack of evidence of any abdominal disease suggests the pain originate from the thorax or have metabolic and neurogenic causes. Especially, neurogenic abdominal pain is recurrent and sustained causalgic pain, regardless of diet and without abdominal distension or rigidity, may be accompanied by signs of neurologic dysfunction. We have experienced a very rare case of abdominal pain arising from the intramedullary cavernous hemangioma of spinal cord. We report this case with a review of the literature.

BACKGROUND/AIMS: Adenosine is an endogenous modulator of nociception. Its role in visceral nociception, particularly in visceral hyperalgesia, has not been studied. The aim of this study was to determine the effects of adenosine receptor agonists in a model of visceral hyperalgesia. METHODS: The visceromotor response (VMR) in rats to colorectal distension (CRD; 80 mmHg, 20 seconds) was quantified by electromyographic recordings from the abdominal musculature. Three hours after the intracolonic administration of zymosan (25 mg/mL, 1 mL), VMRs to CRD were measured before and after either subcutaneous or intrathecal administration of an adenosine receptor agonist. RESULTS: Subcutaneous injection of 5'-N-ethylcarboxyamidoadenosine (NECA; an A1 and A2 receptor agonist), R(-)-N6-(2-phenylisopropyl)-adenosine (R-PIA; a selective A1 receptor agonist), or CGS-21680 hydrochloride (a selective A2a receptor agonist) dose-dependently (10-100 mg/kg) attenuated the VMR to CRD, although hindlimb weakness occurred at the higher doses tested. Intrathecal administration of NECA or R-PIA dose-dependently (0.1-1.0 microgram/kg) decreased the VMR, whereas CGS-21680 hydrochloride was ineffective over the same concentration range. Higher intrathecal doses of the A1/A2 receptor agonist NECA produced motor weakness. CONCLUSIONS: Adenosine receptor agonists are antihyperalgesic, but also produce motor weakness at high doses. However, activation of the spinal A1 receptor significantly attenuates the VMR to CRD without producing motor weakness.

PURPOSE: Billroth I and II reconstructions are commonly performed after a distal subtotal gastrectomy. However, both may cause duodenogastric and duodenogastroesophageal reflux, which are conditions reported to have carcinogenic potential. This study investigated which reconstructive procedure would be most effective in prevent bile reflux into the gastric remnant after a distal gastrectomy. METHODS: A group of 43 patients who underwent a curative distal gastrectomy for gastric cancer were assigned to three groups prospectively according to the reconstructive procedure undertaken: 14, Billroth I (B-I); 14, Billroth II with Braun anastomosis (B-II with Braun); and 15 Billroth II (B-II). The bile reflux period (percent time) for the gastric remnant was measured using a Bilitec 2000 under standardized conditions. The endoscopic findings for reflux gastritis were classified into four grades. RESULTS: The mean standard error time of bile reflux in B-I, B-II with Braun and the B-II groups was 30.9+/-3.9%, 32.8+/-5.1% , and 60.9+/-7.0%, respectively. The B-II group showed significantly higher levels of the % time of bile reflux than the B-I or B-II with Braun groups (P<0.001). Regarding the endoscopic classification for reflux gastritis, the remnant stomach after B-II showed significantly more severe and extensive gastritis than that after the B-I and B-II with Braun procedures (P=0.003). There was also a positive correlation between the degree of % time of bile reflux and the extent of gastritis in the gastric remnant (P<0.001). CONCLUSION: After a distal subtotal gastrectomy, a B-II reconstruction is associated with a high reflux of duodenal content, whereas a Braun enteroenterostomy after a B-II reconstruction minimized the reflux at the levels of a B-I reconstruction.

Patients, aged ≥ 50 years, with gastric neoplasm are reported to be at increased risk for colorectal neoplasia (CRN), while data regarding the risk of CRN in young patients, aged < 50 years with gastric neoplasm are limited. We aimed to investigate the risk of CRN according to the presence of gastric neoplasm in patients, aged < 50 years, and conducted a cross-sectional study on 131,888 asymptomatic examinees who underwent both esophagogastroduodenoscopy (EGD) and colonoscopy as part of a health screening program between 2010 and 2014. The prevalence of overall CRN (8.6% vs. 13.2%, P = 0.251) and advanced colorectal neoplasia (ACRN) (0.0% vs. 1.3%, P = 0.345) did not significantly differ according to the presence of gastric neoplasm in subjects, aged < 50 years. However, among subjects aged ≥ 50 years, patients with gastric neoplasm had a significantly higher proportion of overall CRN (48.2% vs. 31.7%, P < 0.001) and ACRN (12.5% vs. 4.5%, P < 0.001) compared with those without gastric neoplasm. Particularly, gastric neoplasm was an independent risk factor for ACRN after controlling for confounding factors among subjects, aged ≥ 50 years. In conclusion, gastric neoplasm was a risk factor for CRN in patients, aged ≥ 50 years, but not in patients, aged < 50 years. Young patients, aged < 50 years with gastric neoplasm do not need to undergo colonoscopy, whereas patients, aged ≥ 50 years with gastric neoplasm, should be considered a higher priority for colonoscopy.

Intravascular stents have been developed as an adjunct to balloon angioplasty to scaffold the inner vessel surface to improve patency of stenoses and occlusions of arteries and veins. Several types of stents have been described in the literature and have been used in animal experiments as well as in clinical studies, but the clinical application of venous stents is still rather limited and mostly restricted to arteries. We experienced one case of successful palliative treatment in a extrinsically compressed lilac vein by metastatic lymph node using a expandable metallic stent.
