Limited data on laparoscopic and robotic total pelvic exenteration (TPE) for gynecologic, urologic, and rectal malignancies have been published in the literature. Single-incision laparoscopic surgery (SILS) has been successfully introduced for colon cancer. Here, we describe our experience of TPE with SILS þ 1 port (SILSþ1) for advanced rectal cancer. A 64-year-old man was referred to our hospital with anemia. Computed tomography (CT) revealed a rectal tumor that was contiguous with the seminal vesicle and bladder. Rectoscopy revealed an ulcerated, bleeding, and stricturing lesion in the rectum, which was defined as an adenocarcinoma with a moderate degree of differentiation on histologic examination. The patient received neoadjuvant chemotherapy using capecitabine, oxaliplatin, and bevacizumab. After 3 courses of chemotherapy, a rectovesical fistula was suspected from examination of CT images. CT demonstrated intramural gas in the urinary bladder, which suggested a diagnosis of emphysematous cystitis. Thus, we constructed a transverse loop colostomy. Two months after the last administration of chemotherapy, we performed SILSþ1 TPE. The procedure involved a 35-mm incision in the right side of the umbilicus for the insertion of a single multichannel port, and insertion of a 12-mm port into the right lower quadrant. Total operating time was 751 minutes, and estimated blood loss was 1100 mL (including urine).

Key words: Single-incision laparoscopic total pelvic exenteration -Rectal cancer -Reduced port surgery S ingle-incision laparoscopic surgery (SILS) has been successfully introduced for colectomy. [1][2][3][4][5] Total pelvic exenteration (TPE) is the only curative procedure for T4 rectal cancer that directly invades the urinary or gynecologic tract. 6 Cases of laparoscopic and robotic TPE for urologic or gynecologic malignancies have been reported, [7][8][9][10] and multiport laparoscopic TPE for advanced rectal cancer has been reported.11 However, SILS plus 1 port (SILSþ1) TPE for advanced primary rectal cancer has not been examined. In this report, we describe the SILSþ1 TPE for advanced primary rectal cancer.
Patient and MethodsA 64-year-old man was referred to our hospital with anemia. Physical examination and urine and blood tests revealed hemoglobin of 5.7 g/dL. Computed tomography (CT) revealed a rectal tumor (Fig. 1a) that was contiguous with the seminal vesicle and bladder (Fig. 1b). Rectoscopy revealed an ulcerated, bleeding, and stricturing lesion in the rectum with 9 cm from anal verge, which was defined as an adenocarcinoma with a moderate degree of differentiation on histologic examination (Fig. 2). The level of carcinoembryonic antigen (CEA) was 25 ng/mL. The patient received neoadjuvant chemotherapy using capecitabine, oxaliplatin, and bevacizumab without radiotherapy. After 3 courses of chemotherapy, the patient had fecaluria. A rectovesical fistula was suspected from examination of CT i...
