ABSTRACT
A patient presenting to the emergency room with abdominal pain due to acidic cleaner ingestion, whether accidentally or intentionally, should undergo contrast-enhanced computed tomography (CT). If no abnormalities are noted on CT early after ingestion, the patient should be reviewed with a repeat CT within 3-6 h.
ABSTRACT
Portal venous gas (PVG) generally suggests critically ill conditions such as severe bowel ischemia. We herein report a rare case of gallbladder torsion with PVG. An 88-year-old woman complained of right hypogastric pain. Ultrasonography (US) showed diffuse wall thickening of her gallbladder and mobile echogenic foci moving inside the portal venous branches. Computed tomography showed a thickened wall of the gallbladder with poor enhancement and tiny pockets of air in the portal venous branches (segments 4 and 5). There was no evidence of other visceral ischemia. She was diagnosed with necrotic cholecystitis and immediately underwent an emergency operation. We found a gangrenous gallbladder with 180° clockwise rotation along the longitudinal axis and performed cholecystectomy. We confirmed the disappearance of PVG with US after the operation. Her postoperative course was uneventful. Gallbladder diseases can produce PVG, and US might be a useful diagnostic modality to evaluate changes in PVG.
ABSTRACT
The patient was a 64-year-old woman who stabbed her neck with a kitchen knife in an attempt to commit suicide. The tip of the knife was chipped and lodged into the first thoracic vertebra. It was removed using a drill.
ABSTRACT
Arteriovenous malformation (AVM) of the small bowel is a rare disease and can be sometimes difficult to treat due to the diagnostic difficulty. We herein report a case of small intestinal bleeding of AVM successfully treated with double-balloon enteroscopy (DBE) and laparoscope-assisted resection. A 44-year-old man complained of hematochezia and visited the previous doctor. He underwent gastroscopy and colonoscopy, but no bleeding site was detected. However, he rebled 2 days later and became hypotensive. Abdominal computed tomography revealed a hypervascular nodule in the jejunum. He was transferred to our institution for further treatment. DBE was performed and revealed a small pulsatile lesion with a tiny mucosal break. We then injected a marking tattoo. Two days later, he underwent an operation. We were able to easily locate the tattooed lesion laparoscopically and performed jejunal partial resection. His postoperative course was uneventful. DBE enabled a precise diagnosis and minimal invasive surgery.
ABSTRACT
BACKGROUND: An oral combined fluoropyrimidine anticancer drug, tegafur/gimeracil/oteracil potassium (S-1), has recently been used alone or in combination for colon cancer. CASE PRESENTATION: The patient was a 42-year-old man with sigmoid colon cancer with direct invasion of the urinary bladder and multiple costal metastases. A diagnosis of T4, M1, stage IV sigmoid colon cancer was made, and curative resection was considered impossible. S-1 at 50 mg/m2 was administered by oral route from day 1 to day 14. Irinotecan (CPT-11) at 40 mg/m2 was administered by intravenous day 1 and 15. This treatment was followed by 2 weeks absent period, and repeated every 4 weeks. Six cycles of administration were performed in total. Following this treatment, the multiple costal metastases resolved. Down-staging to T3, M0, stage IIA was achieved, and curative resection was judged to be possible. CONCLUSION: Occasional cases in which S-1/CPT-11 therapy was effective have been recently reported. The patient's tumor became resectable despite the discovery of colon cancer associated with bone metastasis at the initial examination, offering hope for cancer patients.
