“…Finally, these data are completed by a recent Japanese study which reported on a significant association between large tumor size (Ͼ5 cm) and presence of direct tumor invasion of urinary organs by sigmoid and rectal cancers. 25 Tumor size was also significantly associated with tumor grade in our analysis. Similar data have been reported by Takeuchi et al 26 who showed that the maximal size of poorly differentiated tumors was significantly larger (72.3 mm) than that of well (42.2 mm) or moderately (52.2 mm) differentiated tumors.…”

“…Previous reports have demonstrated this; even in cases of local advanced colorectal cancer with a colovesical fistula, extended surgery with en-bloc bladder resection contributes to local control and improvement of survival [11,12]. In short, the prognosis depends on the negative surgical margin and the status of the nodal metastasis with or without a colovesical fistula [13,14].…”

Sigmoid colon cancer arising in a diverticulum of the colon with involvement of the urinary bladder: a case report and review of the literature

BackgroundColon cancer can arise from the mucosa in a colonic diverticulum. Although colon diverticulum is a common disease, few cases have been previously reported on colon cancer associated with a diverticulum. We report a rare case of sigmoid colon cancer arising in a diverticulum with involvement of the urinary bladder, which presented characteristic radiographic images.Case presentationA 73-year-old man was admitted to our hospital for macroscopic hematuria. Computed tomography and magnetic resonance imaging revealed a sigmoid colon tumor that protruded into the urinary bladder lumen. The radiographs showed a tumor with a characteristic dumbbell-shaped appearance. Colonoscopy showed a type 1 cancer and multiple diverticula in the sigmoid colon. A diagnosis of sigmoid colon cancer with involvement of the urinary bladder was made based on the pathological findings of the biopsied specimens. We performed sigmoidectomy and total resection of the urinary bladder with colostomy and urinary tract diversion. Histopathological findings showed the presence of a colovesical fistula due to extramurally growing colon cancer. Around the colon cancer, the normal colon mucosa was depressed sharply with lack of the muscular layer, suggesting that the colon cancer was arising from a colon diverticulum.ConclusionThe present case is the first report of sigmoid colon cancer arising in a diverticulum with involvement of the urinary bladder. Due to an accurate preoperative radiological diagnosis, we were able to successfully perform a curative resection for sigmoid colon cancer arising in a diverticulum with involvement of the urinary bladder.

Urinary tract resection is the only procedure that can cure colorectal cancer that directly invades the ureter. In these cases, open surgery is commonly used. Here, we describe our experience of a case of sigmoidectomy following Boari flap construction with single-incision laparoscopic surgery (SILS) for advanced colon cancer with ureteric invasion. A 68-year-old woman was referred to our hospital with left flank pain. Left hydroureteronephrosis was detected on ultrasonography. Computed tomography revealed a solid mass in the sigmoid colon and hydroureteronephrosis due to swelling of a mesenteric lymph node. Computed tomography detected no signs of distant metastasis. Colonoscopy revealed an ulcerated, bleeding, and stricturing lesion in the sigmoid colon, which was identified as an adenocarcinoma with a moderate degree of differentiation at histological examination. Under general anesthesia, the patient was placed in the Trendelenburg semi-right lateral position. An umbilical incision was made for the insertion of a single multichannel port for SILS. Sigmoidectomy and Boari flap reconstruction were performed. There were no perioperative complications. The total operating time was 572 minutes (including Boari flap procedure of 174 minutes), and estimated blood loss was 200 mL. Single-incision laparoscopic sigmoidectomy with Boari flap construction is technically feasible with sigmoid cancer and ureteral invasion.
