  　概要を見る

  In May 2023, the Hugo RAS system obtained pharmaceutical approval for use in gastroenterological surgery in Japan. It is expected to be particularly effective in rectal cancer surgery, which require the manipulation of the deep pelvic cavity and communication with surgeons operating from the intraperitoneal and anal approaches. A 68-year-old woman presented to our hospital with bloody stools and was diagnosed with cStage I (cT2N0M0) rectal cancer and underwent abdominoperineal resection employing the Hugo RAS system. Two arm carts were placed on the left and right lateral sides with an interleg space, and trocars were placed in a straight line between the right superior iliac spine and umbilicus. Herein, we report the first abdominoperineal resection for rectal cancer using the Hugo RAS system.

  BACKGROUND: The da Vinci SP robotic surgical system received regulatory approval for use in colorectal cancer surgery in Japan in April 2023. Given the advantages of the precision of a robot and the postoperative cosmesis of single-site surgery, the system is expected to be further utilized for minimally invasive surgeries, in addition to the curative and safety-assured laparoscopic technique. CASE PRESENTATION: A 73-year-old man presented at our hospital with positive fecal occult blood. He was diagnosed with cT2N0M0 (Stage I) ascending colon cancer and underwent a right hemicolectomy, which was performed with the da Vinci SP system. The operation was performed safely, and the patient was discharged without complications. Pathology findings showed that complete mesocolic excision was achieved. CONCLUSIONS: Herein, we report the first colorectal cancer surgery performed using the da Vinci SP system in Japan. The use of this robotic surgical system with access forms for right hemicolectomy is safe and oncologically appropriate.

  BACKGROUND: The hinotori™ Surgical Robot System was approved for use in colorectal cancer surgery in Japan in 2022. This robot has advantages, such as an operation arm with eight axes, an adjustable arm base, and a flexible three-dimensional viewer, and is expected to be utilized in rectal cancer surgery. Herein, we report the world's first surgery for rectal cancer using the hinotori™ Surgical Robot System. CASE PRESENTATION: A 71-year-old woman presented to our hospital with bloody stools. A colonoscopy revealed type 2 advanced cancer in the rectum, and a histological examination exposed a well-differentiated adenocarcinoma. Abdominal enhanced computed tomography divulged rectal wall thickening without significant swelling of the lymph nodes or distant metastasis. Pelvic magnetic resonance imaging showed tumor invasion beyond the intrinsic rectal muscle layer. The patient was diagnosed with cStage IIa (cT3N0M0) rectal cancer and underwent low anterior resection using the hinotori™ Surgical Robot System. Based on an adequate simulation, surgery was safely performed with appropriate port placement and arm base-angle adjustment. The operating time was 262 min, with a cockpit time of 134 min. Subsequently, the patient was discharged 10 days postoperatively without complications. The pathological diagnosis was pStage IIA (cT3N0M0) and the circumferential resection margin was 6 mm. CONCLUSIONS: We report the first case of low anterior resection for rectal cancer using the hinotori™ Surgical Robot System, in which a safe and appropriate oncological surgery was performed.

  PURPOSE: The low anterior resection syndrome (LARS) score (LS) has been widely validated and has become an international tool for evaluating postoperative bowel dysfunction. However, many physicians still use the conventional incontinence scores in LARS treatment. Moreover, interpretation of LS and its relationship with conventional incontinence scores are not yet well understood. Here we compared the LS with the Cleveland Clinic Incontinence Score (CCIS) to clarify the clinical utility and characteristics of the LARS score. METHODS: We performed a multicentre observational study, recruiting 246 rectal cancer patients following sphincter-preserving surgery. Patients completed the LS, CCIS, and SF36 questionnaires. RESULTS: The response rate was 76.4%, and a total of 180 patients were analysed. The LS was strongly correlated with the CCIS (P < 0.001, rs = 0.727). However, among 116 patients determined to not have incontinence (CCIS 0-5), 51 (44%) were diagnosed with LARS (29 with minor LARS and 22 with major LARS). Among 68 patients without LARS, only 3 were diagnosed as having incontinence (CCIS > 6). In comparison with background factors, aging and elapsed time were associated with only LS. High LS and CCIS both showed significant quality-of-life impairment as assessed by the SF-36. CONCLUSION: This is the first study to determine the difference in the numeric values between the CCIS and LS. The LS can be a convenient tool for LARS screening, identifying a wide range of patients with LARS, including those with incontinence evaluated by CCIS. Assessment using the CCIS may often underestimate LARS.

  A 72-year-old man was diagnosed with tumors outside of the stomach and mesentery of the small intestine on abdominal computed tomography. Histopathological examination of an endoscopic ultrasound-guided fine-needle aspiration biopsy specimen confirmed the diagnosis of lymph node metastasis of a neuroendocrine tumor (NET). Gastroscopy, colonoscopy, small bowel capsule endoscopy, somatostatin receptor scintigraphy, and 18F-fluorodeoxyglucose positron emission tomography were performed. However, the primary lesion could not be diagnosed. The patient underwent surgery, and an ileal submucosal tumor, which was not identified preoperatively in addition to the aforementioned abdominal tumors, was detected. All tumors were diagnosed as NET, and the ileal tumor was considered the primary lesion. The patient has shown no recurrence postoperatively. The current study presents a case of an ileal NET with lymph node metastases in a patient in whom the primary lesion remained preoperatively undiagnosed.
