The risk factors for incisional SSI in emergency colorectal surgery were incision contamination and obesity. Moreover, the incidence of incisional SSI among the incision class IV operations increased significantly with increasing extents of contamination. As a tactic for management of dirty abdominal wounds, we suggest that primary skin closure is suitable in cases of perforation of a prepared colon or colon perforation with localized contamination. On the other hand, in cases of colon perforation with generalized contamination, delayed primary skin closure or leaving an incision open to heal by secondary intention should be considered.
In patients with an elevated preoperative STB level, it is very likely that the inflammation is severe and that the disease has progressed to a severe condition histopathologically; therefore, meticulous attention should be paid to the selection of the surgical procedure, as well as to the postoperative clinical course.
Large vessel invasion is a serious factor determining whether an operation for pancreatic body cancer is feasible. The Appleby operation is a radical operation for the treatment of pancreatic body cancer that has infiltrated the celiac axis. Since this procedure includes a total gastrectomy, the operation is associated with a high morbidity, mortality, and deteriorating postoperative quality of life (QOL). We experienced two cases in which radical operations consisting of a stomach-preserving distal pancreatectomy with en bloc resection of the celiac, common hepatic, and left gastric artery were performed. The use of adjuvant chemotherapy in these cases led to a good postoperative QOL.
An 80-year-old man presented at our hospital with chest oppression and vomiting. An endoscopic examination revealed a tumor in the lower portion of the esophagus, and the patient was diagnosed as possibly having esophageal carcinosarcoma based on a histological examination of endoscopic biopsy specimens. During the initial medical examination, the patient had a high leukocyte count and a high level of serum granulocyte-colony stimulating factor (G-CSF). Moreover, immunohistochemical examination revealed cells that were positive for antibodies against G-CSF. Therefore, we diagnosed the patient as possibly having a G-CSF-producing esophageal carcinosarcoma. The patient died of tumor 4 months after the initial diagnosis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
