The CT scan is most useful in making the diagnosis of intussusception. Colonic lesions should be resected without reduction. Small bowel lesions should be reduced only in patients in whom a benign diagnosis has been strongly suggested preoperatively or in patients in whom resection may result in short gut syndrome.

We present a case of a 32-year-old diabetic woman with Prader–Willi syndrome who developed severe ketoacidosis caused by a sodium-glucose cotransporter 2 (SGLT2) inhibitor, a novel class of antihyperglycemic agents, during a strict low-carbohydrate diet. At admission, a serum glucose level of 191 mg/dL was relatively low, though laboratory evaluations showed severe ketoacidosis. This is the first report of ketoacidosis caused by a SGLT2 inhibitor. It is necessary to not only pay attention when using a SGLT2 inhibitor in patients following a low-carbohydrate diet, but also to start a low-carbohydrate diet in patients treated with a SGLT2 inhibitor because of a high risk for developing ketoacidosis.

Staple closure by means of a Powered Multifire Endo GIA 60 is a simple, quick and safe alternative to the standard suture closure technique, as it reduces the incidence of pancreatic fistula.

When painless, massive, fresh rectal bleeding occurs in elderly and bed-ridden patients, it is important to carefully examine the lower rectum, as there is a strong possibility of AHRU.
