Colon cancer incidentally diagnosed after intestinal obstruction caused by ingested beef bones

We report a case of the incidental diagnosis of an ascending colon cancer following intestinal obstruction due to ingestion of beef bones. A 75-year-old man visited the emergency room with abdominal distension and vomiting for 5 days. He had a history of consuming Korean beef bone soup seven days previously. An abdominal computed tomography scan revealed an ascending colon cancer with an impacted foreign body that was causing intestinal obstruction. On the 11th day after admission, right hemicolectomy was performed. Two bone-like materials were shown in the ascending colon and were pathologically confirmed as cortical bone fragments. The ascending colon cancer was a moderately differentiated adenocarcinoma (pT3N0M0). Surgeons should consider the possibility that colorectal cancer could be the cause of intestinal obstruction when the patient has a history of ingesting a foreign body and the foreign body lodges in the colon and rectum.

Purpose: This study investigated the relationship between the visceral fat area (VFA) and clinico-pathological outcomes in patients with colorectal cancer (CRC). Methods: This retrospective study included 204 patients who underwent anthropometric measurement by bioelectrical impedance analysis (BIA) before surgical treatment for CRC between January 2016 and June 2020. Results: According to the average value of the visceral fat area, 119 (58.3%) patients had a low visceral fat area, and 85 (59.1%) patients had a high visceral fat area. Patients with visceral obesity showed a higher BMI compared to patients without visceral obesity, (21.8±1.9 vs. 25.7±2.5, P<0.001). There was no significant difference in the overall perioperative outcomes including total operation time, time to gas out, sips of water, soft diet, hospital stay, and morbidity between patients in the low and high VFA groups. We divided patients into two subgroups according to the degree of cancer progression and more advanced cases with low VFA showed significantly more total and positive retrieved lymph nodes (LNs) (20.9±10.3 vs. 16.1±7.1, P=0.021 and 3.3±2.9 vs. 2.2±2.3, P=0.019, respectively) and a higher proportion of more than 12 retrieved LNs compared to patients with a high VFA (95.1% vs. 90.0%, P=0.047). Body composition analysis showed that phase angle, muscle composition, and body fluid composition were not statistically different between the two groups. However, body fat mass was statistically higher in the high VFA group (22.0±4.6 vs. 12.8±3.1, P<0.001). Conclusion: Visceral obesity measured by BIA showed lower total and positive retrieved LNs and was not associated with adverse peri-operative outcomes, inflammatory and nutritional, and pathologic outcomes for CRC.
