Single-incision laparoscopic transabdominal preperitoneal repair in the treatment of adult female patients with inguinal hernia.

BACKGROUND: Women have a 3% lifetime chance of developing an inguinal hernia, which is not as common in men. Due to its cosmetic benefits, single-incision laparoscopic transabdominal preperitoneal (SIL-TAPP) inguinal hernia repair is becoming increasingly popular in the management of inguinal hernia in women. However, there are no studies comparing the safety and applicability of SIL-TAPP repair with conventional laparoscopic transabdominal preperitoneal (CL-TAPP) inguinal hernia repair for the treatment of inguinal hernia in women. AIM: To compare the outcomes of SIL-TAPP and CL-TAPP repair in adult female patients with inguinal hernia and to estimate the safety and applicability of SIL-TAPP repair in adult female inguinal hernia patients. METHODS: We retrospectively compared the clinical information and follow-up data of female inguinal hernia patients who underwent SIL-TAPP inguinal hernia repair and those who underwent CL-TAPP inguinal hernia repair at the Affiliated Hospital of Nantong University from February 2018 to December 2020 and assessed the long-term and short-term outcomes of both cohorts. RESULTS: This study included 123 patients, with 71 undergoing SIL-TAPP repair and 52 undergoing CL-TAPP repair. The two cohorts of patients and inguinal hernia characteristics were similar, with no statistically meaningful difference. The rate of intraoperative inferior epigastric vessel injury was lower in patients in the SIL-TAPP cohort (0, 0%) than in patients in the CL-TAPP cohort (4, 7.7%) and was significantly different (P < 0.05). In addition, the median [interquartile range (IQR)] total hospitalization costs were significantly lower in patients in the SIL-TAPP cohort [$3287 (3218-3325)] than in patients in the CL-TAPP cohort [$3511 (3491-3599)]. Postoperatively, the occurrence rate of trocar site hernia was lower in the SIL-TAPP cohort (0, 0%) than in the CL-TAPP cohort (4, 7.7%), and the median (IQR) cosmetic score was significantly higher in the SIL-TAPP cohort [10 (10-10)] than in the CL-TAPP cohort [9 (9-10)]. CONCLUSION: SIL-TAPP repair did not increase the incidence of intraoperative and postoperative complications in female inguinal hernia patients. Moreover, female inguinal hernia patients who underwent SIL-TAPP repair had a lower probability of trocar site hernia and inferior epigastric vessel injury than female inguinal hernia patients who underwent CL-TAPP repair. In addition, female inguinal hernia patients who underwent SIL-TAPP repair reported a more aesthetically pleasing postoperative abdominal incision. Therefore, SIL-TAPP repair is a better option for the treatment of inguinal hernias in women.

Effects of intraoperative fixation of residual hernia sac on postoperative seroma in laparoscopic transabdominal preperitoneal inguinal hernia repair: a prospective randomized controlled trial.

The study was aimed to evaluate a prospective randomized controlled trial (RCT) In laparoscopic transabdominal preperitoneal inguinal hernia repair (TAPP), whether fixation of the residual sac after transecting the hernia sac can reduce the severity of postoperative seroma. A total of 252 male patients with a primary unilateral indirect inguinal hernia who underwent TAPP from September 2018 to November 2022 were recruited. Patients were randomized to the control group (CG)and the experimental group (EG). In the experimental group, after the hernia sac was transected, the residual sac was fixed to the lower edge of the rectus abdominis, while it was left in the preperitoneal space in the control group. Close follow-up was arranged to observe the incidence of seroma and other postoperative complications. All 214 patients were discharged successfully. 106 patients were randomly assigned to the control group, and 108 patients were assigned to the experimental group. There was no significant difference in the incidence of postoperative fluid extraction between the experimental group and the control group (11.1% VS.10.4%, p = 0.862), but the patients with seroma after the operation had fewer repeated extraction (0% VS. 45.5%, P = 0.033). The incidences of other postoperative complications were comparable in the two groups. In the treatment of indirect inguinal hernia with TAPP, after transecting the hernia sac, suturing and fixing the residual sac to the inferior edge of the rectus abdominis can reduce the incidence of repeated aspiration.

Inguinal tumorous mass - an uncommon late manifestation of chronic organized hematoma after laparoscopic transabdominal preperitoneal inguinal hernia repair: Two cases report.

BACKGROUND: Hematoma is a common complication following inguinal hernia repair. It is usually diagnosed early after surgical procedure and is spontaneously, or after evacuation, resorbed. Chronic organized hematoma is rare surgery complication, there is no relevant article after laparoscopic hernia repair in literature. CASES PRESENTATION: 62- and 54-year-old men presented a groin palpable tumorous mass several month after uncomplicated laparoscopic transabdominal preperitoneal inguinal hernia repair. Their dominant complaints were mechanical restrictions. The ultrasound showed a solid formation subcutaneously. The removal and histopathology examination confirmed a chronic organized hematoma and at the same time, this ended the patients 'problems. CONCLUSION: Both patients represent uncommon cases of late postoperative difficulties, uncharacteristic localization of chronic organized hematoma and the need for surgical reintervention to exclude neoplasm.

Nationwide Results on Chronic Pain After Bilateral Transabdominal Preperitoneal Inguinal Hernia Repair.

BACKGROUND: Majority of studies on chronic postoperative inguinal pain has described the occurrence after unilateral inguinal hernia repair. Endo-laparoscopic repair, for example, laparoscopic transabdominal preperitoneal inguinal hernia repair, has been recommended for primary bilateral symptomatic inguinal hernias, although the literature on chronic postoperative inguinal pain among this type of patients is limited. The present study analyzed chronic postoperative inguinal pain following bilateral transabdominal preperitoneal inguinal hernia repair. METHODS: Nationwide consecutive patients who underwent bilateral transabdominal preperitoneal inguinal hernia repair (July 2012-June 2013) were recruited from the Danish Inguinal Hernia Database and cross-checked with hospital files and the National Patient Registry. A prospective follow-up was performed with a standardized postal questionnaire including questions on functional performance status assessed by a modified version of the Activity Assessment Scale. The primary outcome was incidence of chronic postoperative inguinal pain defined as moderate to severe pain-related impairment of everyday activities. Pain was registered according to the two individual groin areas. Furthermore, the overall incidence of chronic postoperative inguinal pain per operated inguinal hernia was calculated. Intensity of experienced pain (Activity Assessment Scale score) was compared between patients reporting pain from one versus both groin areas. RESULTS: In total, 209 patients (418 hernia repairs) were analyzed (questionnaire response rate 83%). The median follow-up time was 27 months (22-34 months). In total, 27 of 209 patients (13%) complained of chronic postoperative inguinal pain from either one (n = 17) or both (n = 10) groin areas after bilateral transabdominal preperitoneal inguinal hernia repair. The incidence of chronic inguinal pain per operated hernia was 9%. The intensity of impairment due to pain (Activity Assessment Scale score) did not differ significantly between patients with chronic postoperative inguinal pain in one (19%) versus both sides (30%), p = 0.056. CONCLUSION: Bilateral transabdominal preperitoneal inguinal hernia repair for symptomatic inguinal hernias was related to a high incidence (13%) of chronic postoperative inguinal pain and decreased functional performance status.

Comparison of peritoneal closure techniques in laparoscopic transabdominal preperitoneal inguinal hernia repair: a prospective randomized study.

PURPOSE: We aimed to compare tacker and suture techniques for peritoneal closure with respect to patient outcomes. METHODS: A total of 64 patients were included in the study, 32 being in the tacker group and 32 in the suture group. All patients underwent laparoscopic TAPP inguinal hernia repair. Both groups were compared with respect to age, sex, duration of peritoneal closure and the operation, hernia type, the number of tackers used for mesh fixation, postoperative complication rate, visual analogue scale (VAS) scores on 1st, 7th, and 30th days, duration of follow-up, and recurrence rates. RESULTS: Duration of peritoneal closure and the operation was significantly shorter in the tacker group compared to the suture group (p < 0.001, p = 0.008, respectively). Statistical analysis with the two-way analysis of variance method revealed that mesh fixation with one or two tackers did not influence postoperative pain. VAS 1 was significantly lower in patients with peritoneal closure with suture compared to the patients undergoing peritoneal closure with tacker (p = 0.027). VAS 7 and VAS 30 were lower for peritoneal closure with suture versus tacker, although the difference did not reach statistical significance (p = 0.064, p = 0.294, respectively). We observed no recurrence at an average of 21-month follow-up. CONCLUSIONS: Tacker and suture appeared to have a comparable safety for peritoneal closure in laparoscopic TAPP inguinal hernia operation. It can be suggested that peritoneal closure with tacker increased short-term pain, independent of the number of tackers used for mesh fixation. Long-term pain was similar in both groups.

Transabdominal preperitoneal versus totally extraperitoneal repair of inguinal hernia: a meta-analysis of randomized studies.

BACKGROUND: The aim of the present study was to comparatively evaluate the outcomes of laparoscopic transabdominal preperitoneal inguinal hernia repair and totally extraperitoneal repair. METHODS: The electronic databases of Medline, EMBASE, and the Cochrane Central Register of Controlled Trials were searched, and a meta-analysis of randomized clinical trials was undertaken. RESULTS: Seven studies comprising 516 patients with 538 inguinal hernia defects were identified. A shorter recovery time (P = .02) was found for totally extraperitoneal repair in comparison with transabdominal preperitoneal inguinal hernia repair (weighted mean difference = -.29; 95% confidence interval [CI], -.71 to .07) although the length of hospitalization (P = .89) was similar in the 2 treatment arms (weighted mean difference = .01; 95% CI, -.13 to .15). Operative morbidity (P = .004) was higher for the preperitoneal approach (odds ratio = 2.15; 95% CI, 1.29 to 3.61). No differences were found with regard to the incidence of recurrence, long-term neuralgia, and operative time. CONCLUSIONS: Current evidence suggests similar operative results for endoscopic and laparoscopic inguinal hernia repair, with a trend toward higher morbidity for the preperitoneal approach. Randomized trials with a longer-term follow-up are needed in order to assess the effect of each approach on the prevention of recurrence.
