Laparoendoscopic single-site extraperitoneal inguinal hernia repair: initial experience in 10 patients

Comparison of transumbilical single-incision laparoscopic TAPP versus conventional laparoscopic TAPP in the elderly: A retrospective analysis

BACKGROUND

To analyze and compare the clinical efficacy of transumbilical single-incision laparoscopic surgery TAPP(SILS-TAPP) and conventional laparoscopic TAPP(CL-TAPP) in the treatment of senile inguinal hernia.

METHODS

From January 2019 to June 2021, a total of 221 elderly patients (≥60 years old) with inguinal hernia received SILS-TAPP and CL-TAPP in General Surgery Department of Affiliated Hospital of Nantong University. The perioperative indicators, postoperative complications and follow-up of the two groups were compared to explore the feasibility and superiority of SILS-TAPP in the treatment of inguinal hernia in the elderly.

RESULTS

There was no difference in demographic characteristics between the two groups. The mean operation time (28.6 ± 4.2 min vs 28.2 ± 5.3 min) in the SILS-TAPP group was not significantly different from that in the CL-TAPP group (Ρ = 0.623), and there was no significant increase in hospital costs(Ρ = 0.748). The intraoperative blood loss (7.4 ± 3.4 ml), VAS score on the postoperative day (2.2 ± 0.7), mean time of resuming activity (8.2 ± 1.9 h) and mean postoperative hospital stay (0.8 ± 0.2 d) in the SILS-TAPP group were better than those in the CL-TAPP group (Ρ < 0. 05).There was no statistical difference in the overall incidence of intraoperative (Ρ = 0.128) and postoperative complications (Ρ = 0.125) between the two groups.

CONCLUSION

Single-incision laparoscopic surgery TAPP (SILS-TAPP) is feasible and effective in elderly patients, providing a new alternative surgical method for patients who can tolerate general anesthesia.

ROBOTIC ASSISTED SINGLE SITE FOR BILATERAL INGUINAL HERNIA REPAIR

Background:

The inguinal hernia is one of the most frequent surgical diseases, being frequent procedure and surgeon´s everyday practice.

Aim:

To present technical details in making hernioplasty using robotic equipment on bilateral inguinal hernia repair with single port and preliminary results with the method.

Method:

The bilateral inguinal hernia repair was performed by using the Single-Site^(c) Da Vinci Surgical Access Platform to the abdominal cavity and the placement of clamps.

Results:

This technique proved to be effective for inguinal hernia and have more aesthetic result when compared to other techniques.

Conclusions:

Inguinal hernia repair robot-assisted with single-trocar is feasible and effective. However, still has higher costs needing surgical team special training.

Risk factors for perioperative complications in inguinal hernia repair - a systematic review

The current literature suggests that perioperative complications occur in 8%–10% of all inguinal hernia repairs. However, the clinical relevance of these complications is currently unknown. In our review, based on 571,445 hernia repairs reported in 39 publications, we identified the following potential risk factors: patient age, ASA score, diabetes, smoking, mode of admission (emergency vs. elective surgery), surgery in low resource settings, type of anesthesia, and (in men) bilateral and sliding hernias. The most commonly reported complications are bleeding (0.9%), wound infection (0.5%), and pulmonary and cardiovascular complications (0.2%). In 3.9% of the included publications, a reliable grading of the reported complications according to Clavien-Dindo classification was possible. Using this classification retrospectively, we could show that, in patients with complications, these are clinically relevant for about 22% of these patients (Clavien-Dindo grade ≥IIIa). About 78% of all patients suffered from complications needing only minor (meaning mostly medical) intervention (Clavien-Dindo grade <III). Especially with regard to the low incidence of complications in inguinal hernia repair, future studies should use the Clavien-Dindo classification to achieve better comparability between studies, thus enabling better correlation with potential risk factors.

A systematic review comparing single-incision versus multi-incision laparoscopic surgery for inguinal hernia repair with mesh

OBJECTIVE

The objective of this article is to evaluate whether the surgical outcomes differ between single incision laparoscopic surgery (SILS) versus multi-incision laparoscopic surgery (MILS) for the repair of inguinal hernia.

METHODS

A systematic review of the literature on published studies reporting the surgical outcomes following SILS versus MILS for inguinal hernia repair was undertaken using the principles of meta-analysis.

RESULTS

Fifteen comparative studies on 1651 patients evaluating the surgical outcomes in patients undergoing SILS versus MILS for inguinal hernia repair were systematically analysed. The post-operative recovery time was significantly quicker [odds ratio, -0.35 (CI, -0.57 - 0.14), p = 0.001] following SILS compared to MILS procedure. However, the statistical equivalence was seen in outcomes of length of hospital stay, operative time both for unilateral and bilateral hernias, post-operative pain score, one-week pain score, hernia recurrence [odds ratio, 1.24 (CI, 0.47-3.23), p = 0.66], conversion [odds ratio, 1.07 (CI, 0.37-3.12), p = 0.90], and post-operative complications [odds ratio, 0.95 (CI, 0.66-1.36, p = 0.78] between two approaches. The sub-group analysis of four included randomized, controlled trials showed similarities between outcomes following SILS and MILS except slightly higher postoperative pain score in MILS group.

CONCLUSIONS

Both SILS and MILS approaches of inguinal hernia repair are feasible, safe and can be offered to patients depending upon the availability of expertise and resources.

Single-port versus conventional laparoscopic total extra-peritoneal inguinal hernia repair: a prospective, randomized, controlled clinical trial

BACKGROUND

The advantage of single-port total extra-peritoneal (TEP) inguinal hernia repair over the conventional technique is still debatable. Our objective was to compare the outcomes of TEP inguinal hernia repair using either a single-port or conventional surgical technique, in two blind randomized groups of patients.

METHODS

In this prospective, randomized, double-blind, controlled clinical trial, 100 patients undergoing surgery for unilateral inguinal hernia were randomized into two groups: One group underwent conventional laparoscopic TEP inguinal hernia repair, while the other was selected for single-port TEP repair. Primary endpoint is postoperative pain (VAS), while secondary endpoints are recurrence, chronic pain and complications.

RESULTS

From 100 patients, 49 underwent single-port hernia TEP repair, 50 had conventional three-port TEP hernia repair, and one patient declined to participate after randomization. The two groups were comparable in terms of patient demographics and operative findings. Mean operative time was 49.1(±13.8) min in the conventional group and 54.1(±14.4) min in the single-port group (p = 0.08). Mean hospital stay was 19.7(±5.8) h in the conventional group and 20.5(±6.4) h in the single-port group (p = 0.489). No major complications and no recurrence reported at 11-month follow-up. No statistically significant difference noted in postoperative pain between the two groups at regular intervals.

CONCLUSIONS

The outcomes after laparoscopic TEP inguinal hernia repair with a single-port device are similar but not superior to the conventional technique.

Single site and conventional totally extraperitoneal techniques for uncomplicated inguinal hernia repair: A comparative study

OBJECTIVE:

To demonstrate the feasibility of endoscopic extraperitoneal single site (EESS) inguinal hernia repair and compare it outcomes with the conventional totally extraperitoneal (TEP) technique.

BACKGROUND:

TEP inguinal hernia repair is a widely accepted alternative to conventional open technique with several perioperative advantages. Transumbilical laparoendoscopic singlesite surgery (LESS) is an emerging approach and has been reported for a number of surgical procedures with superior aesthetic results but other advantages need to be proven.

PATIENTS AND METHODS:

Thirty-eight uncomplicated inguinal hernias were repaired by EESS approach between January 2010 and January 2011. All procedures were performed through a 25 cm infraumbilical incision using the Alexis wound retractor attached to a surgical glove and three trocars. Body mass index, age, operative time, blood loss, complications, conversion rate, analgesia requirement, hospital stay, return to normal activities and patient satisfaction with aesthetic results were analysed and compared with the last 38 matched-pair group of patients who underwent a conventional TEP inguinal hernia repair by the same surgeon.

RESULTS:

All procedures were performed successfully with no conversion. In both unilateral and bilateral EESS inguinal repairs, the mean operative time was longer than conventional TEP (55± 20 vs. 40± 15 min, P = 0.049 and 70± 15 vs. 55± 10 min, P = 0.014). Aesthetic result was superior in the EESS group (2.88± 0.43 vs. 2.79± 0.51, P = 0.042). There was no difference between the two approaches regarding blood loss, complications, hospital stay, time until returns to normal activities and analgesic requirement.

CONCLUSION:

EESS inguinal hernia repair is safe and effective, with superior cosmetic results in the treatment of uncomplicated inguinal hernias. Other advantages of this new technique still need to be proven.

The role of the laparoendoscopic single site totally extraperitoneal approach to inguinal hernia repairs: a review and meta-analysis of the literature

BACKGROUND

Laparoendoscopic single site (LESS) surgery may have perceived benefits of reduced visible scarring compared to conventional laparoscopic (LAP) totally extraperitoneal (TEP) hernia repairs. We reviewed the literature to compare LESS TEP inguinal hernia repairs with LAP TEP repairs.

METHODS

We searched electronic databases for research published between January 2008 and January 2012.

RESULTS

A total of 13 studies reported on 325 patients. The duration of surgery was 40-98 minutes for unilateral hernia and 41-121 minutes for bilateral repairs. Three studies involving 287 patients compared LESS TEP (n = 128) with LAP TEP (n = 159). There were no significant differences in operative duration for unilateral hernias (p = 0.63) or bilateral repairs (p = 0.29), and there were no significant differences in hospital stay (p > 0.99), intraoperative complications (p = 0.82) or early recurrence rates (p = 0.82). There was a trend toward earlier return to activity in the LESS TEP group (p = 0.07).

CONCLUSION

Laparoendoscopic single site surgery TEP hernia repair is a relatively new technique and appears to be safe and effective. Advantages, such as less visible scarring, mean patients may opt for LESS TEP over LAP TEP. Further studies with clear definitions of outcome measures and robust follow-up to assess patient satisfaction, return to normal daily activities and recurrence are needed to strengthen the evidence.

Single port laparoscopic totally extraperitoneal hernioplasty: a comparative study of short-term outcome with conventional laparoscopic totally extraperitoneal hernioplasty

BACKGROUND

Recently, single port laparoscopic surgery has begun to develop as an extension of minimally invasive surgery, but there have been only a few reports of single port laparoscopic totally extraperitoneal (SPLTEP) hernioplasty. In addition, there are few comparative studies with conventional laparoscopic totally extraperitoneal (CLTEP) hernioplasty. The aim of the present study was to report our experience with SPLTEP hernioplasty and to compare short-term outcomes for SPLTEP hernioplasty with CLTEP hernioplasty.

METHODS

Data were prospectively collected for all patients undergoing SPLTEP hernioplasty for inguinal hernia at Incheon St. Mary's Hospital, Incheon, Korea. Data for the SPLTEP group (n = 76 patients enrolled between June 2010 and May 2011) were compared retrospectively with data for the CLTEP group (n = 93 patients enrolled between June 2009 and May 2010).

RESULTS

There were no significant differences in patient demographics. This study showed no significant difference in terms of operative time between the two groups (SPLTEP group 54.0 min vs. CLTEP group 47.8 min; p = 0.07). There were no conversions to conventional TEP hernioplasty or transabdominal preperitoneal hernioplasty or open surgery in SPLTEP hernioplasty. Morbidity rates were 7.9 % (n = 6) in the SPLTEP group and 10.8 % (n = 10) in the CLTEP group, and the difference was not significant.

CONCLUSIONS

Single port laparoscopic totally extraperitoneal hernioplasty is technically feasible and the short-term operative outcome is comparable to that of CLTEP hernioplasty. Future large-scale prospective controlled studies and long-term analysis are needed to establish the cosmetic outcomes, quality of life, long-term recurrence rate, and long-term complication rate of SPLTEP hernioplasty.

[Hernia surgery in urology: part 1: inguinal, femoral and umbilical hernias - fundamentals of clinical diagnostics and treatment]

Hernias are a common occurrence with correspondingly huge clinical and economic impacts on the healthcare system. The most common forms of hernia which need to be diagnosed and treated in routine urological work are inguinal and umbilical hernias. With the objective of reconstructing and stabilizing the inguinal canal there are the possibilities of open and minimally invasive surgery and both methods can be performed with suture or mesh repair. Indications for surgery of umbilical hernias are infrequent although this is possible with little effort under local anesthesia. This article presents an overview of the epidemiology, pathogenesis, clinical symptoms, diagnostics and therapy of inguinal, femoral and umbilical hernias.
