Carotid stump syndrome (CSS) is known to be one of the causes of recurrent ipsilateral ischemic stroke following the occlusion of the internal carotid artery (ICA). The present study describes a case of left CSS in a 50-year-old patient presenting with a central retinal artery embolism following internal carotid and middle cerebral artery occlusion. The central retinal artery embolism was belie...

Left upper lobectomy may be followed by complications such as thrombus formation in a stump of the left superior pulmonary vein (LSPV), which may cause systemic embolization. We have encountered four such cases, which account for 3.4% of all left upper lobectomies performed at our institution. Right renal infarction was observed in one of these four cases; the remaining cases were asymptomatic,...

We investigated the use of direct lengthening of the distal stump of a peripheral nerve to compare the results of nerve regeneration using the direct lengthening method with simple end-to-end suture and autografting in rats. A segment 10 mm long was resected from the rat sciatic nerve (n=18 in each group). The distal nerve stump was fixed to a ring and pulled at a rate of 1 mm/day for 20 days u...

When dealing with gastric cancer with duodenal invasion, gastrectomy with distal resection of the duodenum is necessary to achieve negative distal margin. However, rupture of an ultralow duodenal stump necessitates advanced surgical skills and close postoperative observation. The present study reports a case of an early duodenal stump rupture after subtotal gastrectomy with resection of the who...

BACKGROUND Gastric stump carcinoma is an exceptional and poorly known long-term complication after pancreaticoduodenectomy. CASES PRESENTATION Two patients developed gastric stump carcinoma 19 and 10 years after pancreaticoduodenectomy for malignant ampulloma and total pancreaticoduodenectomy for pancreatic adenocarcinoma, respectively. Both patients had pT4 signet-ring cell carcinoma involvi...

Electrical currents near regenerating newt limbs were measured with a recently developed vibrating probe. Steady currents with local surface densities of 10 to 100 muA/cm2 or more leave the end of the stump during the first 5-10 days after amputation and are balanced by currents with densities of only 1-3 muA/cm2 that enter the intact skin around the stump. They are immediately dependent upon t...

This research was designed to determine whether or not a normal stump musculature is required for normal morphogenesis of muscle within the regenerating amphibian limb. Limbs of adult axolotls were amputated proximal to the elbow, and approximately 99% of the skeletal muscle was removed from the limb stump. The early stages of regeneration and blastema formation followed a relatively normal mor...

Stump appendicitis is an acute inflammation of the residual appendix and is a rare complication after appendectomy. The physician should be aware of the possibility of stump appendicitis in patients with right lower abdominal pain after appendectomy so that delayed diagnosis and treatment can be prevented. Stump appendicitis is usually treated by surgical resection, and endoscopic treatment has...

Background: Herein we present a rare case of metastatic tumor in transverse colon originating from an asymptomatic gastric stump cancer. Case presentation: A 55-year-old woman underwent partial gastrectomy and pyloroplasty for the gastrointestinal stromal tumor in the stomach in 2006. She developed abdominal fullness and a reduced appetite in April 2015. Colonoscopy and computerized tomography ...

The timing of morphogenetic events in the regenerating forelimb of the axolotl was investigated by rotation of limb coverings at well-defined stages in the regenerative process. Both the skin covering the stump and the epidermis covering the regenerate were manipulated independently and together as a unit. The results show that the transmission of morphogenetic information covers a broad range ...
