Conjunctival congestion after laparoscopic operation in children: A retrospective case series in a single-centre children's medical centre

Abstract

Objective: In the present study, we report a retrospective analysis of 23 cases of conjunctival congestion after laparoscopic operation in children and try to explore the causes and intervention measures. Methods and Results: This is a retrospective, single-centre and observational study, and all patients with conjunctival congestion after laparoscopic operation admitted to our institution between August 2021 and December 2021 were included in this study. Records of 23 patients including 16 male patients and 7 female patients were retrospectively analysed. These patients were in the age group of 2–12 years. Their primary symptom was different degrees of conjunctival congestion, and the symptom onset was between 2 and 7 days after laparoscopic operation, including laparoscopic inguinal hernia repair, laparoscopic appendectomies, laparoscopic Meckel's diverticulectomy, laparoscopic removal of foreign body ingestions and laparoscopic choledochal cystectomy, and the duration of operations varies from 20 min to 255 min. The symptom disappeared from 5 to 21 days after the operation, and the duration of the symptom ranged from 2 to 14 days. A total of 1718 operations were performed, of which 461 were laparoscopic and 1257 were general operations, the incidence of conjunctival congestion after laparoscopic surgery was 23/461, and compared with 0/1257 after ordinary surgery, there was a significant difference between them. Of these 23 patients, 5 patients received no treatment and the other 18 patients were intervened with steroid-containing eye drops. Although eye drops containing steroids can significantly relieve eye discomfort, the duration of conjunctival congestion between the two groups (i.e. steroid-containing eye drop treated vs. non-steroid-containing eye drop treated) did not differ significantly. All patients recovered well. In the follow-up till the end of February 2022, no serious complications had occurred. Conclusion: Conjunctival congestion after laparoscopic operation is extremely rare in children, and the underlying causes are still unclear. We speculate that the pressure of pneumoperitoneum may be the main cause of this phenomenon. Symptoms may be self-limiting, and steroid-containing eye drops can relieve effectively the discomfort.
