The meta-analysis and systematic review of prevalence and clinical anatomy of the arc of Buhler.

The arc of Buhler (AOB) is a direct anastomosis of the celiac axis and superior mesenteric artery. This paper reviews the literature on the AOB and provides accurate and up-to-date data on its prevalence, anatomy, and clinical significance. The main scholarly online databases were carefully searched for relevant studies related to the AOB. Information was gathered and formed the basis of the analysis of this study. In total, 11 studies were used in this meta-study, consisting of 3685 total patients tested and 50 cases of the AOB presented. The pooled prevalence estimate of the AOB was determined to be 1.7% (95% CI 0.9, 2.9). By imaging type, the prevalence of the AOB was 1.8% for radiological studies (n = 3485; 95% CI 0.9, 3.0), 1.4% for computed tomography (CT) studies (n = 1417; 95% CI 0.4, 3.0), and 1.9% for angiography studies (n = 2068; 95% CI 0.5, 4.0). The AOB is sufficiently significant and should be considered when planning surgeries or radiological procedures involving the abdomen.

On the border of medical specialties: ovarian metastasis from colorectal cancer.

The colon cancer (CC) is the fourth most common cancer in the world. It is associated with metastatic spread in 50% of cases in the course of the disease. Common sites for synchronous metastases from colorectal cancer are the lung, liver, peritoneum, bone and brain. The frequency of ovarian metastasis from CC varies widely from 1.6 to 7.4%. This type of metastasis is difficult to distinguish clinically from primary ovarian neoplasms. We present a case of a 49-years old woman admitted to the Department of General Surgery at the 5th Military Clinical Hospital in Cracow for elective surgery for metastatic obstructive sigmoid cancer. Computed tomography (CT) showed a large tumor in the right ovarian field. Brief recommendations regarding that issue based on the available literature has been summarized as well.
