Laparoscopic Sugarbaker repair is the main operation method of parastomal hernia, and mesh fixation is the key technical link. This study develops a novel mesh fixation method and discusses its clinical application effect.

From June 2017 to June 2019, 66 cases with parastomal hernia undergoing laparoscopic Sugarbaker repair in the Sixth Affiliated Hospital of Sun Yat-sen University were analyzed retrospectively. The patients were divided into trial group and control group according to different methods of mesh fixation, with 41 cases in the trial group by "contraposition and alignment" mesh fixation, and 25 cases in the control group by traditional double loop hernia nail fixation. The clinical data and outcome of the two groups were compared.

There were no significant differences in gender, age, body mass index, course of disease and classification of parastomal hernia between the two groups. The mesh fixation time in the trial group was shorter than that in the control group [(32.6±9.0) min vs (38.7±11.0) min, P<0.05]. There were no significant differences between the two groups in terms of the number of hernia nail, seroma, mesh infection, and postoperative hospital stay. Cases were followed up for (37.6±14.8) months in the trial group, for (38.8±15.2) months in the control group, with no significant difference (P=0.687). The recurrence rate of parastomal hernia in the trial group was 2.4%, which was lower than 20.0% in the control group (P<0.05). There was no significant difference in the incidence of postoperative chronic pain between the two groups (24.2% vs 24.0%, P=0.971).

The "contraposition and alignment" mesh fixation represents a valid method to shorten the time of mesh fixation and reduce the recurrence of parastomal hernia in laparoscopic Sugarbaker repair. It can be popularized in clinical treatment for parastomal hernia.
