A 59-year-old woman underwent laparoscopic staging surgery for malignant uterine tumors and recovered well. However, nausea and vomiting occurred on the eighth day after operation, and her anal exhaust did not stop. A soft mass was found in the subcutaneous tissue of the left lower abdomen on physical examination. The “spring sign” was indicated on the plain film ( Fig. 1A). Ultrasound suggested that the weak echo area ( Figs. 1B– 3) was located in the muscular layer and connected to the abdominal cavity through a “channel” with an inner diameter of about 0.7 cm.

Abdominal computed tomography scan revealed a left lower abdominal wall hernia ( Figs. 1C and 4). The hernia was a local, small intestinal hernia. After consultation, the surgeon diagnosed an abdominal incisional hernia, which occurred in the 5-mm trocar puncture hole. Subsequently, the patient underwent surgery for abdominal wall repair and recovered well.
