[A Case of Sigmoid Colon Cancer with Liver Metastasis and Gastric Infiltration for Which Ileus Surgery Was the Impetus for Surgery].

The case is a woman in her 60s. Sigmoid colon cancer surgery, liver metastasis surgery, and adjuvant chemotherapy were performed at another hospital 2 years ago. Later, she developed a metastasis in her liver and was recommended surgery, but she refused treatment and was transferred. Her liver metastasis had invaded the stomach and formed a giant gastric ulcer. This time she had an adhesive ileus and underwent laparoscopic surgery at our hospital. At that time, we observed the state of liver metastasis and gastric infiltration by laparoscopy, so we thought that palliative surgery was possible and recommended it. Although she initially refused treatment, the relative ease with which her ileus surgery was performed encouraged her to undergo palliative surgery. Laparoscopic-assisted gastrectomy and partial hepatectomy were performed, and she was discharged on hospital day 13 after surgery. She subsequently developed liver metastases and died 8 months after palliative surgery, although she was able to eat and maintain her ADL until the end of life. By staying close to the patient, we were able to lead the patient from refusal of surgery to palliative surgery, and we felt that we were able to make the patient reach a favorable end.

Acute intestinal necrosis due to multiple thrombosis in COVID-19 patient. Report of a case.

BACKGROUND: While thrombosis is a well-known complication of coronavirus disease 2019 (COVID-19) infection, reports on intestinal necrosis due to intestinal ischemia caused by thrombosis are extremely rare. We herein report a case of intestinal necrosis due to multiple thrombosis in a COVID-19 patient. CASE PRESENTATION: The patient was a 64-year-old man. He was admitted to hospital after being diagnosed with COVID-19, the severity was classified as moderate II. Nasal High Flow™ management was conducted along with treatment with tocilizumab, remdesivir, and dexamethasone. Heparin was also administered due to high D-dimer values. As abdominal pain appeared from the 6th day of hospitalization, contrast-enhanced CT was performed, which confirmed multiple thrombosis in the aorta. However, no obvious intestinal ischemia was found. On the 10th day of hospitalization, the patient's abdominal pain was exacerbated. Upon re-evaluation by CT, he was diagnosed with perforative peritonitis due to ileal ischemic necrosis and emergency surgery was performed. Intraoperative examination revealed perforation due to necrosis at multiple sites in the ileum; thus, partial ileectomy was carried out. Pathological findings also revealed discontinuous multiple intestinal necrosis due to the frequent occurrence of thrombosis. Following surgery, the patient recuperated and was discharged after ventilator management and multimodal therapy at the ICU. CONCLUSIONS: Thrombosis due to COVID-19 complications is rare in the intestinal tract, but also occur. Its initial symptoms might not be captured by CT images, therefore caution is required.

A case of ileus surgery using the water pressure method against ileus caused by incarceration into the inverted bladder diverticulum.

BACKGROUND: Ileus is quite a common disease, but is associated with various causes. As far as we know, there have only been one case of ileus due to inverted bladder diverticulum, which is extremely rare. CASE PRESENTATION: The patient was a 53-year-old male. He made an emergency visit to our hospital with a chief complaint of left lower quadrant pain. He underwent right inguinal hernia surgery at 2 years of age with no history of laparotomy. An abdominal enhanced CT revealed inversion of the bladder left side wall where part of enlarged small intestine was found. Ascites were also found between the incarcerated small intestine and the bladder, leading to a diagnosis of strangulation ileus due to internal hernia and subsequent emergency surgery. A laparotomy revealed incarceration of the small intestine in the bladder left wall as a Richter type. The incarceration was rigid. We believed it would be difficult to pull out by extraction. Therefore, we inserted a Nelaton catheter between the incarcerated small intestine and the bladder and carried out the water pressure method to release the ileus. We did not perform an enterectomy since no manifest necrosis or perforation of the small intestine was found. The inverted bladder wall was a partial depression. We interpreted it to be a bladder diverticulum. We made a suture for occlusion with the bladder diverticulum inverted. Ileus arising from inverted bladder diverticulum is a very rare disease state. We hereinafter report on this case along with bibliographical considerations. CONCLUSIONS: We experienced a case of small intestine ileus due to inverted bladder diverticulum, which is very rare. In terms of preservation of the bowel, we believed the water pressure method to release the ileus was useful.
