There are some modifiable and non-modifiable risk factors for SSI. IRI and age are non-modifiable, whereas the timing of surgery and diabetes can be modulated by trying to defer some emergency procedures to elective ones and normalizing the glycemia of diabetic patients.
Sigmoidectomy reduces concerns about diverticulitis and behavioral changes due to the disease. Quality of life should be considered when referring patients with uncomplicated diverticulitis to surgery. Prospective studies are required to confirm this result.
Five-year survival was 70.6 percent in patients with no lymph node involvement, 68.2 percent in patients with pararectal lymph nodes N+, 25 percent in patients with involvement of intermediate lymph nodes, and 30 percent in patients with involvement of lumboaortic lymph nodes. In no case was there involvement of the hypogastric lymph nodes. On the basis of our experience and from results in the literature, we consider an upward extended lymphadenectomy with high ligation of the inferior mesenteric artery is warranted since it enables the tumor to be staged accurately and may lead to survival even in cases of advanced lymph node involvement.
LE for rectal carcinoma might only be successfully performed in selected patients with correct preoperative staging. In the LE cases reported five-year overall survival, local recurrence, and in-hospital mortality were similar to APR and SSR, while there was a statistically significant difference following LE in terms of specific morbidity.
16 splenic grafts and 24 accessory spleens were evaluated with ultrasound, colour Doppler and power Doppler imaging, in order to compare the features of splenic grafts and accessory spleens. 12 splenic grafts (11 surgically implanted, 1 islet of splenosis) were detected in eight patients following splenectomy 6-12 months previously. Four of the surgically implanted splenic grafts were found in three patients following splenectomy 16-18 days previously. 21 accessory spleens were incidentally detected in 20 subjects who had not been operated upon, whereas three enlarged accessory spleens were found in 10 patients who underwent splenectomy 6-12 months previously. The size, shape, rim features, echogenicity, acoustic enhancement and vascularization of the splenic grafts and accessory spleens were evaluated. The splenic grafts were oval with lobulated margins, an inhomogeneous pattern in 36% and acoustic enhancement in 64%. Multiple feeding vessels arising from the surrounding tissue entered the periphery of 10 splenic grafts in the eight patients operated on 6-12 months previously, whereas no vascular signals were detected in the four splenic grafts of the three patients operated on 16-18 days ago. Accessory spleens were round with smooth echogenic margins and a vascular hilum arising from the splenic vessels. In conclusion colour Doppler and power Doppler allow differentiation between accessory spleens and splenic grafts basing on their shape and vascular supply.
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.
