Multiple diverticulosis of jejunum represents an uncommon pathology of the small bowel. The disease is usually asymptomatic and must be taken into consideration in cases of unexplained malabsorption, anemia, chronic abdominal pain or discomfort. Related complications such as diverticulitis, perforation, bleeding or intestinal obstruction appear in 10-30% of the patients increasing morbidity and mortality rates. We herein report a case of a 55 year-old man presented at the emergency department with acute abdominal pain, vomiting and fever. Preoperative radiological examination followed by laparotomy revealed multiple giant jejunal diverticula causing intestinal obstruction. We also review the literature for this uncommon disease. © 2011 Falidas et al; licensee BioMed Central Ltd.

Background: Primary retroperitoneal mucinous cystadenoma of borderline malignancy represents a rare tumor, with unclear histogenesis, concerning almost exclusively women. Only two cases concerning male patients have been reported.Case report: We herein report a case of a 37 year old man undergone laparotomy for a sizable retroperitoneal tumor resulting after the histological examination to a primary retroperitoneal mucinous cystadenoma of borderline malignancy.Conclusion: This is the third case of primary retroperitoneal mucinous cystadenoma of borderline malignancy in a male patient reported in the literature. The preoperative diagnosis is impossible. Laparotomy constitutes the only diagnostic and curative approach. © 2011 Falidas et al; licensee BioMed Central Ltd.

Sclerosing mesenteritis (SM) is a rare pathological condition affecting the mesentery. It is a benign, non-specific inflammation of the adipose tissue of the mesentery of the small intestine and colon. It is characterized by a variable amount of chronic fibrosis. Its etiology is unknown, the pathogenesis is obscure, while the pathological characteristics of the disease are unspecific. The initial clinical presentation varies from typically asymptomatic to that of an acute abdomen. The diagnosis is suggested by computed tomography but is usually confirmed by surgical biopsies. Treatment is largely empirical; it is decided upon on the basis of the clinical condition of the patient, and usually a few specific drugs are used. Surgical resection is sometimes attempted for definitive therapy, although the surgical approach is often limited. We will present five cases of SM as well as a review of the available literature in order to state and compare a variety of clinical presentations, diverse possible etiologies and dissimilar treatment options. © 2011 Vlachos et al; licensee BioMed Central Ltd.

Purpose: Colorectal carcinomas that arise proximal (right) or distal (left) to the splenic flexure exhibit different clinical and biological characteristics. Although various hypotheses have been proposed to explain these differences, their origin remains unclear. In this study we investigated the clinicopathologic differences between left and right colon tumors and comment on the possible explanatory theories behind them. Methods: This study included a total of 388 retrospectively collected cases of colorectal cancer, surgically treated from 1999 to 2004. Differences of patients 'demographic data and tumor micro- and macroscopic characteristics between left and right-sided tumors were investigated and analysed. Results: Patients with right-sided colon cancer were significantly older (mean age 70 vs. 68 years; p <0.05) and had more lymph nodes examined than patients with left colon tumors (mean number of nodes 18.9 vs. 12.6; p <0.05). There was a lower proportion of T1 stage right-sided tumors (3.1 vs. 5%) and a higher proportion of stage T2-4 (96.9 vs. 95%) compared with left-sided tumors (p <0.001 for χ2 test of all T stages). Furthermore, right-sided tumors had a higher mean width and depth (4.3 vs. 3.8 cm and 1.8 vs. 1.6 cm, respectively; p <0.05). Finally, there was a higher percentage of poorly differentiated right colon tumors (41.4 vs. 17.5%; p <0.001). Conclusion: Right-sided colon tumors affect older patients and are diagnosed at more advanced disease stages. The underlying mechanisms that provoke these differences remain unclear. Further studies are needed in order to better understand the true nature of these differences and their possible clinical implications. © 2010 Zerbinis Medical Publications.

INTRODUCTION: Intra-abdominal drains have been widely used in order to prevent intra-abdominal fluid accumulation and detection of anastomotic leakage. PRESENTATION OF CASE: We herein report a case of small bowel herniation followed by strangulation in an 82 year old woman who had undergone sigmoidectomy for colorectal cancer. DISCUSSION: Although several complications related to drain usage such as drainsite infection, hemorrhage and intestinal perforation may occur, intestinal incarceration through drain site is rarely reported. CONCLUSION: Drains must be used with caution and only if indicated. Careful insertion, regular postoperative or post-removal inspection is strongly recommended. © 2011 Surgical Associates Ltd.
