title: Blood flow evaluation using PINPOINT® in a case of incarcerated inguinal hernia: A case report.
abstract: Indocyanine green (ICG) fluorescence for intestinal blood flow has been reported, but application during laparoscopic surgery for incarcerated inguinal hernia has not been reported. Here, we report the case of a patient with an incarcerated inguinal hernia in whom the bowel was preserved after evaluation of intestinal blood flow with ICG fluorescence using PINPOINT®, a brightfield full-color, near-infrared fluorescence camera. A man in his 80s was diagnosed with incarcerated inguinal hernia and underwent laparoscopic surgery. The ascending colon and mesentery showed deep red discoloration on gross evaluation. However, intravenous injection of ICG revealed uniform fluorescence of the mesentery and bowel wall, indicating the absence of irreversible ischemic changes of the bowel. As such, no resection was performed, and transabdominal preperitoneal patch plasty was completed. The patient had a good postoperative course. In this case, ICG fluorescence with the PINPOINT was useful to avoid bowel resection during laparoscopic surgery.
