To investigate the effect of laparoscopy on the diagnosis and treatment of closed abdominal injury. A total of 26 patients with closed abdominal injury admitted to our hospital from January 2016 to January 2019 were searched. All patients were treated by laparoscopy. All patient reports were made with the informed consent of the patients. All patients were diagnosed clearly during operation. Among them, there were 3 cases of gastric perforation, 2 cases of liver rupture, 13 cases of spleen rupture, 3 cases of small intestine rupture, 1 case of liver round ligament laceration, 2 cases of small mesenteric vascular laceration, 1 case of colon liver mesenteric laceration, and 1 case of retroperitoneal hematoma. Of the 26 patients in this group, 23 (88.5%) completed laparoscopically or laparoscopically assisted; 5 cases (19.3%) only performed laparoscopic exploration without special treatment, and 3 cases (11.5%) switched to laparotomy. The blood loss was 50-2000 ml (mean 500 ml), and the operative time was 60-180min (mean 128min). The length of hospital stay was 3-21 d (mean 9 d). There were no complications or deaths related to laparoscopy in the whole group. Conclusion Laparoscopic technique has the advantages of less trauma, high diagnosis rate and fast recovery. It can also be used for surgical treatment in the diagnosis and treatment of closed abdominal injury, so as to achieve the purpose of comprehensive diagnosis and treatment. The limitations of laparoscopy should also be noted.
