Laparoscopic wedge resection (LWR) for intraluminal gastrointestinal stromal tumor (GIST) leads to excessive resection of normal gastric wall. We report a case of GIST around the cardia successfully treated with full-thickness partial resection using a hybrid approach of laparoscopic surgery and single-incision intragastric surgery (SIIGS). A 69-year-old woman had a 5 cm intraluminal GIST at the posterior wall around the cardia. Submucosal injection of glycerin and indigo carmine was performed with transoral endoscopy. Circumferential seromuscular incision followed by placement of seromuscular sutures to invert the lesion into the stomach was performed under laparoscopy. By SIIGS, resection of the inverted mucosa and retrieval of the tumor were completed. A hybrid approach consisting of laparoscopic wall-inversion surgery and SIIGS was useful for intraluminal GIST and may expand the indications for laparoscopic wall-inversion surgery by removing size limitations. 相似文献

Background/Purpose: Endoscopic lithotomy is a useful medical procedure for treating choledocholithiasis. Although this procedure is commonly
performed, complications such as pancreatitis and cholangitis are recognized as major and serious problems. The obstruction
of bile and pancreatic juice flow caused by papillary edema or spasm is thought to be responsible for such complications.
We have developed a new bent-type tube stent that can drain bile and pancreatic juice simultaneously.
Methods: From June to November 2001, temporary implantation of the new bent-type tube stent was performed in four patients (two women,
two men; mean age, 73.3 years) with choledocholithiasis, for the drainage of bile and pancreatic juice simultaneously after
endoscopic lithotomy by endoscopic sphincterotomy or endoscopic balloon sphincter dilatation.
Results: Immediately after the implantation of the new type of tube stent, bile and pancreatic juice flow from the respective ducts
was recognized under endoscopic observation. Neither pancreatitis nor cholangitis occurred after these procedures.
Conclusions: This procedure may be a helpful means to prevent pancreatitis and cholangitis after endoscopic lithotomy.

Recent research has focused on the effects of ambient particulate pollution and much evidence has indicated that particulate pollution is associated with the onset of asthma and allergy; however, the effect of diesel exhaust particles (DEP) on the development of allergen-induced airway remodeling has not been fully investigated in vivo. In the present study, we examined the effects of DEP on Dermatophagoides farinae allergens (Der f)–induced asthma-like phenotypes in mice. Mice were administered i.t. 8 times with Der f. DEP were injected i.t. with Der f 4 times throughout the experiment or twice at the sensitization period. In both cases, DEP aggravated Der f–induced increases in airway responsiveness to acetylcholine, the number of eosinophils and neutrophils in the bronchoalveolar lavage fluid (BALF), serum Der f–specific IgG1 levels, Th2 cytokines and transforming growth factor-β 1 levels in BALF, and amount of hydroxyproline in the right lungs. Furthermore, goblet cell hyperplasia and subepithelial fibrosis were also markedly aggravated. These findings indicate that DEP can potentiate airway remodeling induced by repeated allergen challenge as well as Th2-drived airway hyperresponsiveness, eosinophilic inflammation, and IgG1 production and that DEP can exhibit adjuvant activity for airway remodeling, probably due to the enhancement of allergen sensitization and/or of Th2 polarizing pathways. 相似文献

We report on a 22-year-old man with congenital hypogammaglobulinemia who developed multiple colorectal neoplasms. An immunodeficiency had been diagnosed in the patient since two years of age, and this time many tumors of the sigmoid colon and rectum were detected by barium enema and fiberscopy. Abdominoperineal resection was performed, and the resected specimen revealed 29 polyps, including 9 adenocarcinomas and 20 adenomas. The carcinomas, measuring 0.8 to 11.0 cm in size, showed various depths of invasion, and the adenomas, measuring 0.2 to 1.5 cm in size, showed various degrees of epithelial atypia. DNA analysis demonstrated that the tumors were heterogeneous, showing different DNA index and ploidy patterns. The pathogenetic relation between malignancy and immunodeficiency is also reviewed. 相似文献

To examine whether donor-derived cells could exist in nonhematopoietic tissues of recipients after allogeneic hematopoietic stem-cell transplantation, we examined the patterns of the short tandem repeat (STR) of DNA extracted from fingernail clippings of recipients so that the contamination of blood cells was excluded. All 21 patients reached donor-derived hematopoiesis after transplantation and 20 of them were in remission of the primary diseases at the time of sampling. Compared with the STRs of donor cells, among 9 of 21 patients, DNA extracted from fingernail samples showed coexistence of the donor pattern of the STRs, sharing from 8.9% to 72.9% of total STR areas. Time from transplantation to sampling was from 305 to 2399 days among positive cases. These results demonstrate for the first time the existence of stable contribution of donor cells in fingernails among recipients of allogeneic hematopoietic stem cells. 相似文献

An appropriate trigger for BCR-ABL1 mutation analysis has not yet been established in unselected cohorts of chronic-phase chronic myelogenous leukemia patients. We examined 92 patients after 12 months of tyrosine kinase inhibitor (TKI) treatment in Nagasaki Prefecture, Japan. Univariate analysis revealed that significant factors associated with not attaining a major molecular response (MMR) were the presence of the minor BCR-ABL1 fusion gene, a low daily dose of TKI, and the emergence of BCR-ABL1 kinase domain mutations conferring resistance to imatinib. Factors associated with the loss of sustained MMR were a low daily dose of TKI and the emergence of alternatively spliced BCR-ABL1 mRNA with a 35-nucleotide insertion. Taken together, our results suggest that the search for BCR-ABL1 mutations should be initiated if patients have not achieved MMR following 12 months of TKI treatment. 相似文献

A 60-year-old woman was pointed out a tumor, 2.6 cm in diameter, at the pancreas body, by screening ultrasonography examination. Jaundice and anemia were absent and no abdominal mass was palpable on physical examination. Enhanced CT revealed the tumor directly invaded to splenic vein, but lymph node metastases were not detected. ERCP showed a pancreatic duct was obstructed by the tumor, accompanied with dilatation of the peripheral pancreas duct. Because we cannot rule out the malignancy tumor, pancreatoduodenectomy and lymphadenectomy was done. The tumor was very hard and serosal invasion was suspicious in the operative findings. Histopathological study showed that the tumor was occupied with colloid differentiation, in which free mucinous epithelial malignant cells were floating. Then we diagnosed the tumor to be pancreatic mucinous carcinoma. Extra pancreatic extension such as vascular involvement was not proved microscopically. However, ten months after the resection, CT scan showed a recurrent tumor sized 4 cm diameter, at the middle abdominal cavity, which suspected to be disseminated diseases. Mucinous carcinoma occurs relatively rare in pancreas, of which the incidence is 1 .4% in pancreatic adenocarcinomas. We report herein the pancreatic mucinous carcinoma case with a calcificated region, which resulted in early recurrence with abdominal seeding. 相似文献
