[Richter's hernia: a clinical case and the clinico-therapeutic considerations]. Fornaro R, Terrizzi A, Davini MD, Canaletti M, Baldi E, Bonfante P, Sticchi C, Cavaliere D, Ferraris R. The authors report a case of Richter's hernia. They underline main clinical and therapeutic patterns, emphasizing the need of an early diagnosis and surgery. This is a hernia of abdominal wall with partial entrapment of bowel wall (antimesenteric site) through a small ring. The incidence increased in the last years because of diffusion of laparoscopic techniques. Richter's hernia could be asymptomatic for a long time or show vanish sign. Sometimes this hernia can be diagnosed during surgery. The clinical signs are conclamated if hernia is complicated by strangulation. High mortality is justified by performing too late diagnosis and operation.
