Effect of complete reduction of hernia sac and transection of hernia sac during laparoscopic indirect inguinal hernia repair on seroma

Introduction

This study investigated the effect of complete reduction and transection of the hernia sac during laparoscopic indirect inguinal hernia repair on seroma.

Methods

Retrospective analysis was performed on 1763 cases undergoing laparoscopic indirect inguinal hernia repair in three centers from January 2017 to September 2019, among them, 311 patients with transection of hernia sac and 1452 patients with reduction of hernia sac, the data of the two groups were tested by t-test. Logistic univariate analysis was performed on 233 cases of postoperative seroma, and variables p < 0.05 in univariate analysis were included for multivariate analysis. Then, the transection group and the reduction group were matched with 1:1 propensity score matching, and the caliper value was set at 0.05. Finally, 274 patients matched in each group were analyzed by univariate analysis again to evaluate whether the transection of hernia sac had an impact on postoperative seroma.

Results

The results of univariate analysis of 233 patients with postoperative seroma showed that: ASA-3 p = 0.031, classification-L3 p < 0.001, surgery-TEP p < 0.001, transect group p = 0.005. The results of multivariate analysis show that: ASA-3 p < 0.001, classification-L3 p < 0.001, surgery-TEP p < 0.001, transect group p = 0.020. The results of univariate analysis after propensity score matching showed that transection of the hernia sac is significant for postoperative seroma (p < 0.001).

Conclusion

Transection of the hernia sac during laparoscopic indirect inguinal hernia repair can significantly lead to postoperative seroma.

Porcine Small Intestinal Submucosa Mesh to Treat Inguinal Hernia in Young Adults Using Laparoscopic Inguinal Hernia Repair: A Retrospective Controlled Study

BACKGROUND

The authors evaluated the effects and clinical value of small intestinal submucosa (SIS) mesh to treat inguinal hernia in young adults by the laparoscopic method.

METHODS

The clinical data of 357 cases with inguinal hernia using SIS mesh in our hospital were analyzed retrospectively from June 2014 to June 2018. All cases were divided into 2 groups according to the surgical method. Operation time, hospital stay, cost, postoperative complications, and complications during follow-up were analyzed.

RESULTS

Of the 357 patients, 202 (56.6%) underwent Lichtenstein repair and 155 (43.4%) underwent transabdominal preperitoneal (TAPP) repair. Operation time and hospital costs of the Lichtenstein group were significantly lower compared with the TAPP group (P<0.05). The incidence of seroma in the Lichtenstein group was lower than that in the TAPP group at 1 week, 1 month, and 3 months postoperatively with significant differences (P<0.05). Perioperative pain scores in the Lichtenstein group were higher than the TAPP group (P<0.05). No statistical difference was observed for hospital stay between 2 groups (P>0.05). In the Lichtenstein group, 1 case recurred during the follow-up period (0.5%). No intestinal obstruction or intestinal fistula occurred in any patient during the follow-up period.

CONCLUSION

The effect of SIS mesh was positive whether the patient underwent a Lichtenstein or TAPP method. Seroma was more common in the TAPP method that may cause lower postoperative pain. Therefore, we recommend individualized treatment.

Clinical value of the laparoscopic transabdominal preperitoneal technique in recurrent inguinal hernia repair

OBJECTIVE

To assess the clinical value of the laparoscopic transabdominal preperitoneal (TAPP) technique in recurrent inguinal hernia repair.

METHODS

The clinical data of 354 patients with recurrent inguinal hernia who underwent TAPP surgery from June 2010 to June 2016 at the Department of Hernia and Abdominal Wall Surgery, Beijing Chaoyang Hospital, Capital Medical University, were retrospectively analyzed.

RESULTS

Laparoscopic surgery was successfully completed in all 360 patients. Among them TAPP were finished in 354 patients, while TAPP repair were attempted but finally converted to open or TAPE repair in 6 patients. The mean operation time was 54.7 ± 19.4 min (range 30-90 min), mean duration of hospitalization was 4.7 ± 2.1 days (range 2-14 days), and mean duration of follow-up was 37.7 ± 12.4 months (range 12-60 months). The rate of intraoperative injury was 4.5% (16/354), and the rate of postoperative complications was 13.6% (48/354). No patient developed a foreign body sensation, wound infection, intestinal obstruction, mesh infection, or chronic pain. Two patients (0.6%) developed re-recurrence requiring reoperation, with no further recurrence.

CONCLUSION

When performed by an experienced surgeon with excellent technique, the TAPP technique is safe and effective for recurrent hernia after surgical treatment via the anterior repair, and maybe a good alternative for recurrent hernia after surgical treatment via the posterior repair.

Application of shaft method assisted biological mesh in laparoscopic inguinal hernia repair

To compare the feasibility and advantage of traditional tiling method and shaft method to place biological mesh following laparoscopic repair of inguinal hernia.Sixty cases from January 2013 to January 2014 treated with laparoscopic inguinal hernia neoplasty with biological patches were included. All the cases were randomly divided into control group and observation group. Observation group was treated with shaft method to place biological mesh, while control group was treated with traditional tiling method. The length of the operation, hospital fees, and rate of occurrence of surgical complications were compared.All 60 cases were successfully treated with laparoscope inguinal hernia repair. None were converted to open operations. Total operation times for the observation group and control group were 54 ± 4.5 and 71 ± 7.2 minutes, respectively (P < .05). The hospital fees of the observation group and control group were 21,280 ± 365 RenMinBi Yuan (RMB) and 24,280 ± 428 RMB, respectively (P < .05). The rates of occurrence of surgical complications were 3.33% (1/30) and 16.7% (5/30), respectively (P < .05).The shaft method can be applied in laparoscopic inguinal hernia repair with biological mesh. Compared with the traditional method, the shaft method has apparent advantages, fewer complications during and after the operation.
