The feasibility and safety of single-incision totally extraperitoneal inguinal hernia repair after previous lower abdominal surgery: 350 procedures at a single center

Risk of conversion after intended total extraperitoneal hernia repair for inguinal hernia depends on type of previous abdominal surgery

PURPOSE

Risk of total extraperitoneal hernia repair (TEP) in patients with previous lower abdominal surgery (PLAS) is still debated. The present study was designed to assess the rate of conversion in TEP for inguinal hernia stratified by type of PLAS.

METHODS

Variables on patients undergoing TEP inguinal hernia repair at our center were prospectively collected between July 2012 and May 2018. Patients with PLAS were compared to patients without PLAS. Furthermore, the most frequent subtypes of PLAS were defined and TEP conversion rate was stratified according to type of PLAS.

RESULTS

A total of 1589 patients with TEP inguinal hernia repair were identified including 152 (9.6%) patients with PLAS. Operative time was increased in patients with PLAS (70 vs. 60 min, p < 0.001). Conversion from TEP to transabdominal preperitoneal patch plasty (TAPP) or Lichtenstein open inguinal hernia repair was eight-times more frequent after PLAS (8% vs. 1%, p < 0.001). Considering type of PLAS, open appendectomy was most frequently encountered, followed by multiple PLAS and surgery to the bladder and prostate (53%, 11% and 10%). After stratification for type of PLAS, conversions were most frequently found after previous surgery to the bladder or prostate and after multiple PLAS (conversion rate of 20% and 24%, p < 0.001). In contrast, conversion rate after open appendectomy was not increased.

CONCLUSION

PLAS to the bladder and prostate is associated with TEP conversion. Selected patients might profit from a different operative approach for inguinal hernia repair.

TPP (totally preperitoneal) making single incision laparoscopic inguinal hernia repair more feasible: a comparison with single incision laparoscopic totally extraperitoneal hernioplasty (SIL-TEP)

BACKGROUND

Totally preperitoneal hernioplasty (TPP) is a concept which was introduced for distinguishing with totally extraperitoneal (TEP). There is few evidence reflecting the single incision laparoscopic totally preperitoneal (SIL-TPP) characteristic. The aim of study is to demonstrate the feasibility of single incision laparoscopic totally preperitoneal hernioplasty (SIL-TPP) and compare the outcomes with the single incision laparoscopic totally extraperitoneal hernioplasty (SIL-TEP) technique.

METHODS

During August 2018 and July 2022, 200 inguinal hernia patients received SIL-TPP and 56 patients received SIL-TEP in the First hospital of Ningbo university. The demographics, clinical characteristics, intraoperative and postoperative parameters were retrospectively analysed.

RESULTS

SIL-TPP and SIL-TEP hernia repair were successfully conducted in all patients. There was no conversation happened in two group. Patients' demographics were comparable when compared between the two groups adding the comparison initial 52 cases analysis (P > 0.05). The mean unilateral hernia operative time was significant shorter in the SIL-TPP group than SIL-TEP group (unilateral: 81.38 ± 25.32 vs. 95.96 ± 28.54, P: 0.001). Further study of unilateral hernia operative time revealed the mean indirect hernia operative time was significant shorter in the SIL-TPP group than SIL-TEP group (indirect: 81.38 ± 25.33 vs. 95.87 ± 28.54, P: 0.001). The unilateral hernia operation time trend of initial 52 cases of two group analysis revealed the operation time of SIL-TPP reduced faster than SIL-TEP along with treating number increasing (Figs. 2 and 3). The comparison of initial equal quantity unilateral hernia patient mean operative time revealed the SIL-TPP group was significant shorter than SIL-TEP group (85.77 ± 22.76 vs. 95.87 ± 28.54, P: 0.049). The rate of peritoneum tearing of SIL-TPP group was significant high than SIL-TEP (P = 0.005).

CONCLUSION

SIL-TPP hernia repair is a superior procedure and possess its own distinguished advantages. We recommend it rather than SIL-TEP for treating inguinal hernia, especially for indirect hernia. However, large-scale randomized controlled trials comparing SIL-TPP and SIL-TEP are needed to confirm these results.

Single incision laparoscopic totally preperitoneal hernioplasty (SIL-TPP): Lessons learned from 102 procedures and initial experience

BACKGROUND

The abdominal wall in groin area is conventionally considered that it was comprised by 9 layers. Single incision laparoscopy totally extraperitoneal hernioplasty (SIL-TEP) reported before were operated through the front of the posterior rectus sheath.

METHOD

102 SIL-TPP were conducted from October 2018 to October 2020 at The Affiliated Hospital of Medical School of Ningbo University using a self-made single-port device and standard laparoscopic instruments. Clinical data, demographic and intraoperative findings, and short-term postoperative outcomes were analyzed.

RESULTS

Of the 102 hernias treated, 46 were right inguinal hernias, 33 were left inguinal hernias and 23 were double-side inguinal hernias. All patients received the SIL-TPP and no conversion happened. The mean left-side and right-side hernia operative time was almost same. The left-side and right-side operative time were 75.48 ± 26.95 and 76.24 ± 26.09 minutes, respectively. The mean operative time was 75.92 ± 26.45 (range, 29-170 minutes) in unilateral inguinal hernia. Mean operative time was 104.17 ± 28.58 minutes (range, 67-180 minutes) in double-side inguinal hernia. The intraoperative complications rate was 21.57 (22/102) and all the complications were Peritoneum or sac tearing. Postoperative complications occurred in 3 cases (1 case wound seroma, 1 case urinary retension and 1 case upper respiratory infection) and were successfully treated conservatively. The mean hospital stay was 2.8646 ± 1.38 days. The 24 hours Visual analogue scale score was 2.28 ± 0.77. During follow-up to June 2022, no recurrence case occurred.

CONCLUSION

SIL-TPP is safe and feasible. SIL-TPP has its unique skills and advantages to treat inguinal hernia. Large-scale randomized controlled trials comparing SIL-TPP inguinal hernia repair with conventional single port and conventional three port laparoscopic totally extraperitoneal hernioplasty with short-term outcome and long-term recurrence rate are needed to confirm these results.

Laparoscopic mesh removal for mesh infection related to pararectal incision of previous appendectomy after laparoscopic total extraperitoneal inguinal hernia repair: A case report

A 67-year-old man with a history of appendectomy 40 years ago underwent single-incision laparoscopic surgery for total extraperitoneal inguinal hernia repair. Postoperatively, the pararectal incisional scar obtained from the appendectomy was infected; thus, antibiotic therapy and drainage were performed. However, the infection persisted. After 5 postoperative months, the mesh was laparoscopically removed at a sufficient distance from the infected site. No enterocutaneous fistula was observed. After 1 year and 10 months, no recurrence of hernia or infection was observed. Thus, laparoscopic mesh removal is feasible. Infection of a 40-year-old incision rarely results in mesh infection. Therefore, in pararectal incision, the extent of mesh coverage should be considered; if the overlap is large, changing the technique by not covering the incision may be necessary.

Long-term outcomes of single-incision versus multiport laparoscopic totally extra-peritoneal inguinal hernia repair: a single-institution experience of 186 consecutive cases

PURPOSE

This retrospective study was conducted to compare the long-term outcomes of single-incision totally extraperitoneal (S-TEP) inguinal hernia repair and conventional multiport totally extraperitoneal (M-TEP) inguinal hernia repair.

METHODS

The study population included 186 consecutive patients (S-TEP, n = 149; M-TEP, n = 37) who underwent elective surgery for inguinal hernia at Osaka Police Hospital between 2011 and 2013.

RESULTS

No significant between-group difference was found in patient or hernia characteristics or in perioperative outcomes, with the exception of age (S-TEP group vs. M-TEP group: median 69 [IQR 60-75] years vs. 64 [55-69] years, respectively; P = 0.019). Furthermore, no significant between-group difference was found in follow-up time (5.5 [3.0-5.8] vs. 5.4 [3.1-5.7] years, P = 0.839), recurrence rate (0.6 vs. 2.4%, P = 0.358), chronic pain (1.2 vs. 0%, P = 1.000), feeling the mesh (2.3 vs. 7.1%, P = 0.142), or movement limitation (0.6 vs. 0%, P = 1.000). All chronic symptoms were "mild but not bothersome." A metachronous contralateral inguinal hernia developed in 8.1% of patients.

CONCLUSION

The long-term outcomes of S-TEP repair were comparable to those of M-TEP, with rates of recurrence, chronic pain, feeling the mesh, and movement limitation falling within acceptable limits.

Single-incision laparoscopic totally extraperitoneal inguinal hernia repair with tumescent local anesthesia: report of more than 2000 procedures at a day-surgery clinic

PURPOSE

The purpose of this study was to evaluate the feasibility and safety of single-incision laparoscopic surgery for totally extraperitoneal inguinal hernia repair (SILS-TEP) with tumescent local anesthesia (TLA) at a day-surgery clinic.

METHODS

We analyzed, retrospectively, 2148 patients who underwent SILS-TEP under general anesthesia with TLA between April, 2015 and March, 2020 at Gi surgical clinic, to evaluate their operative outcomes. The TLA agent, consisting of normal saline and lidocaine with epinephrine and ropivacaine, was injected during surgery.

RESULTS

The median operative times for unilateral and bilateral hernia were 50 min and 75 min, respectively. Blood loss was minimal in all patients. Conversion to the Lichtenstein method was required in 4% (91/2148) of patients. The median recovery room stay was 125 min and no analgesics were required in the recovery room by 75% (1613/2148) of the patients. All the patients left the clinic on the day of surgery. Complications developed in 6.5% (139/2148) of the patients, as seromas in 6% (125/2148), wound infections in 0.4% (8/2148), and hematomas in 0.2% (4/2148), respectively. Bowel injury and obstruction each occurred in 0.05% (1/2148) of the patients. There were no hernia recurrences.

CONCLUSION

SILS-TEP with TLA can be performed safely at a day-surgery clinic.

Tips for operation of inguinal hernia after implantation of artificial urinary sphincter following radical prostatectomy: report of two cases

Urinary incontinence is one of the common complications after radical prostatectomy along with inguinal hernia. Artificial urethral sphincter implantation is widely accepted as a treatment option. We report two surgical cases of inguinal hernia after artificial urethral sphincter implantation for urinary incontinence following radical prostatectomy. In Case 1, since the device went through the inguinal canal, adhesion around the pubis was extremely hard. In Case 2, the device was placed on the ventral side of the rectus abdominis muscle, so it was operable almost as normal. In each case, the surgical procedure was considered carefully after confirming the location of the device by preoperative computed tomography and ultrasonography. Hernia repair was successfully performed using the Lichtenstein method. There are few reports regarding surgical repair of inguinal hernia following artificial urinary sphincter implantation. Preoperative image and appropriate choice of approach could facilitate safe and secure surgery.

Single-incision laparoscopic totally extraperitoneal repair for bilateral inguinal hernias after femoral-femoral artery bypass in a patient on antiplatelet therapy: A case report

A 77-year-old man visited our hospital due to bilateral painful inguinal swellings. He had a history of femoral-femoral artery bypass surgery for peripheral artery disease and took ethyl icosapentate. Additionally, he had a previous history of open left colectomy for descending colon cancer and had a median incision reaching the lower abdomen. With a diagnosis of bilateral direct inguinal hernias after femoral-femoral artery bypass surgery, he underwent single-incision laparoscopic surgery for totally extraperitoneal repair, continuing on ethyl icosapentate. During surgery, the preperitoneal space was safely and easily dissected, avoiding a subcutaneous vascular graft. No perioperative complications or hernia recurrence have been observed at 3 months follow-up.

Meta-analysis of totally extraperitoneal inguinal hernia repair in patients with previous lower abdominal surgery

BACKGROUND

Previous lower abdominal surgery is considered a relative contraindication to laparoscopic totally extraperitoneal (TEP) inguinal hernia repair. This was a meta-analysis of studies comparing the feasibility and safety of TEP repair between patients with (PS), and without (NS) a history of lower abdominal surgery.

METHODS

A systematic literature search was undertaken for studies comparing the outcome of TEP inguinal hernia repair in patients with, and without previous lower abdominal surgery. Data on postoperative outcomes were extracted and compared by meta-analysis. Odds ratios (ORs) and mean differences with 95 per cent confidence intervals were calculated.

RESULTS

Seven comparative cohort studies were identified, involving a total of 1657 procedures (PS 326, NS 1331). There was a statistically significant difference between PS and NS favouring the NS group with regard to both primary outcomes: intraoperative morbidity (OR 2·85, 95 per cent c.i. 1·19 to 6·80; P = 0·02; 7 studies; I²  = 33 per cent), and postoperative morbidity in the multiport subgroup (OR 2·14, 1·28 to 3·58; P = 0·004; 5 studies; I²  = 0 per cent). For the secondary endpoints conversion rate, peritoneal tears, major intraoperative bleeding, postoperative haematoseroma and delay in return to normal activities, there was a statistically significant difference favouring the NS group.

CONCLUSION

This study suggests that patients with previous lower abdominal surgery who need hernia repair get less benefit from TEP repair than those with no history of surgery.
