A 72-year-old male was transported to our hospital with complaints of heart palpitations and dyspnea since a month earlier and was immobile. Blood examination showed severe anemia, and colonoscopy revealed circumferential tumors in the rectum and the sigmoid colon. Histopathologic examination revealed the tumors as squamous cell carcinoma of the rectum and adenocarcinoma of the sigmoid colon.

Case Presentation: The patient was a 62-year-old Asian male with a history of endoscopic colorectal adenoma resection and a spontaneous pneumothorax. The patient had no history of a laparotomy.

We investigated 36 patients with Stage Ⅳ rectal cancer who underwent primary resection in our department between November 2015 and June 2020. Tumor localization was upper in 20 cases and lower in 16 cases. Six patients had the cT4b stage at initial diagnosis, and lateral lymph node metastases were detected in 6 cases.

We planned to treat the AML first, and then the colorectal cancer. After completion of 1 course of CAG therapy(cytarabine, aclarubicin, G‒CSF), his white blood cell count increased sufficiently, so he underwent a robot‒assisted Hartmann operation in October.

However, there have been some reports on such issues as an increase in the incidence of postoperative complications and an increase in postoperative hospital stay in patients who underwent neoadjuvant chemotherapy(NAC); thus, we summarized and are reporting the short-term results of our experience in patients seen in our department to date. A total of 76 patients with rectal cancer who underwent robot-assisted surgery, and short-term postoperative results were compared between patients who underwent neoadjuvant chemotherapy (NAC group)and those who did not undergo neoadjuvant chemotherapy(non-NAC group).

The aim of the present study was to clarify the advantages of robotic-assisted laparoscopic lateral lymph node dissection (RALLD), comparing its short-term outcomes with those of laparoscopic lateral lymph node dissection (LLLD). There are some retrospective reports comparing RALLD or LLLD and open lateral lymph node dissection (OLLD), but few reports comparing RALLD and LLND to each other.

The patient was an 80s man who was referred to the department of gastroenterology of our hospital for earlystage esophageal cancer by a local physician. ESD was performed for a lesion(Lt, 0-Ⅱa+Ⅱc, cT1N0M0, StageⅠ)located 35- 38 cm from the incisors.

In addition, because laparoscopic lateral lymph node dissection(LLND)in positive cases of metastasis to the lateral lymph nodes is difficult, it has not been commonly used. Here, we report the treatment results of neoadjuvant chemotherapy(NAC)and subsequent laparoscopic total mesorectal excision(TME)plus LLND in cases of lower rectal cancer with metastasis to the lateral lymph nodes.

In the latest Japanese gastric cancer treatment guidelines, PAM plus paclitaxel(PTX)was positioned as a second-line chemotherapy for advanced gastric cancer. We report a case of advanced gastric cancer with peritoneal dissemination after gastrectomy effectively treated with RAM plus PTX.
