Bilateral Inguinal Hernia Repair: Laparoscopic Totally Extraperitoneal Versus Open Lichtenstein

ABSTRACTObjectives:Laparoscopic total extraperitoneal (TEP) hernia repair is one of the widely used surgical methods for symptomatic inguinal hernia. Although laparoscopic procedures provide advantages on postoperative complications and shorter convalescence, there is currently no global consensus on the timing for returning to work following laparoscopic hernia repair. This study compared the outcomes of early and late return to work after laparoscopic TEP inguinal hernia repair.Materials and Methods:Between March 2008 and December 2019, we reviewed 506 cases of laparoendoscopic TEP hernia repair. Among these, 231 cases where patients returned to work within 1 week postsurgery were classified as the early group, while 275 cases of patients either unemployed or returning to work after more than 1 week were classified as the late group. The primary endpoint was inguinal hernia recurrence. The secondary endpoints included postoperative chronic inguinal pain (defined as persistent pain 6 months postoperation), seroma formation, and the physical function domain of SF-36 v2.Results:The two groups had similar baseline characteristics, except that the early return-to-work group was younger (51 ± 13.1 vs. 58.2 ± 15.9, P < 0.001) and had a lower risk of constipation before the operation (10.0% vs. 18.5%, P = 0.006). The early group did not exhibit an increased rate of inguinal hernia recurrence (1.7% vs. 2.9%, P = 0.386). In addition, the early group experienced significantly less chronic pain (4.8% vs. 11.6%, P = 0.006). There were no differences in postoperative seroma formation or scores of the physical function domain of SF-36 v2 between the early and late groups.Conclusion:Patients who underwent laparoscopic TEP hernia repair and returned to work within 1 week did not show increased hernia recurrence rates or complications. In addition, early return to work was associated with significantly less chronic pain. Returning to work early after TEP repair is both safe and feasible. Patients are encouraged to resume work early following TEP repair.

Modification of standard laparoscopic total extra peritoneal hernia repair technique: Methods to improve feasibility in the UK health service

PurposeIn the early 1990's laparoscopic hernioplasty gained popularity worldwide. Thereafter, laparoscopic surgeons have attempted to improve cosmesis using single port surgery. This study aims to introduce and assess the safety and feasibility of single port laparoscopic total extraperitoneal (TEP) hernia repair with a nearly-scarless umbilical incision.MethodsSixty three single port laparoscopic TEP hernia repairs were performed in sixty patients from June 2010 to March 2011 at Incheon St. Mary's Hospital, with the use of a glove single-port device and standard laparoscopic instruments. Demographic and clinical data, intraoperative findings, and postoperative course were reviewed.ResultsOf the 63 hernias treated, 31 were right inguinal hernias, 26 were left inguinal hernias and 3 were both inguinal hernias. There was one conversion to conventional three port laparoscopic transabdominal preperitoneal hernioplasty. Mean operative time was 62 minutes (range, 32 to 150 minutes). There were no intraoperative complications. Postoperative complications occurred in two cases (wound seroma and urinary retension) and were successfully treated conservatively. Mean hospital stay was 2.15 days.ConclusionSingleport laparoscopic TEP hernia repair is safe and feasible. Umbilical incision provides an excellent cosmetic outcome. Prospective randomized studies comparing single port and conventional three port laparoscopic TEP repairs with short-term outcome and long-term recurrence rate are needed for confirmation.

To compare institutional costs for open versus laparoscopic inguinal hernia repair and its relationship to reimbursement in an ambulatory surgery center in the United States. Analysis of institutional costs in US$ of 2006 for all nonreusables used in a laparoscopic total extraperitoneal (TEP) hernia repair using a polyester mesh compared with open hernia repair using polypropylene mesh. A comparison of the institution's disposable costs related to reimbursement at an ambulatory surgery center in Southeastern United States was performed to identify the most cost-effective procedure for the outpatient facility. As fixed and indirect costs of the ambulatory surgery center are similar for both procedures, a cost difference can only be found in direct disposable costs with that being US$ 235.57 for the procedure-specific disposables in the laparoscopic hernia repair as compared with US$ 117.15 for the open hernia repair. Cost for identical disposables used in both procedures amounted to US$ 32.57. Laparoscopic TEP hernia repair has a higher cost for procedure related disposables versus the open hernia repair at +US$ 118.42 mainly being due to the more costly polyester mesh. A flat rate reimbursement of US$ 1800 for a laparoscopic procedure compared with only US$ 950 for the open procedure minus all disposable cost results in a higher institutional income of +US&$ 731.58 (US$ 1531.86 vs. US$ 800.28), from which other institutional costs can be paid. Despite marginally higher procedure-related disposable costs for laparoscopic TEP hernia repair, the institutional income is remarkably higher owing to a better reimbursement for this procedure in ambulatory surgery centers. From the institution's point of view, laparoscopic hernia repair is by far the more cost-effective procedure when compared with an open hernia procedure at the present time.

To compare the results, feasibility, and effectiveness of laparoscopic total extraperitoneal (TEP) hernia repair made using anatomical hydrophilic mesh and polypropylene mesh. Descriptive study. Department of General Surgery, Recepc Tayyip Erdoğan University Training and Research Hospital, Rize, Turkey and Department of General Surgery, Ondokuz Mayıs University Medical Faculty, Samsun, Turkey from January 2017 to October 2020. Comparative analysis on patient who had TEP for inguinal hernia. Group 1 included repairs using hydrophilic anatomical mesh, Group 2 included repairs using polypropylene mesh. Both were compared for operation times, complications, and return to work. There were 34 patients in Group 1 and 31 patients in Group 2. The average operation time was shorter in Group 1 (p = 0.001). Postoperative complications, were significantly less common in Group 1 (p = 0.045). Patients were able to return to their work-life earlier in Group 1 after surgery (p = 0.001). Both anatomic mesh and polypropylene mesh can be used in TEP hernia repair. These two materials stand out with their different properties. Whereas anatomical mesh shortens the operation time, decreases the rate of postoperative complications, and enables the early return to work, polypropylene mesh is cost-effective and easily accessible.

Background: Hernias of the abdominal wall constitute an important public health problem. Laparoscopic inguinal hernia repair (TEP) is a minimal access surgical procedure as compared to open hernia repair. The objective of the study was to compare open and laparoscopic hernia repair in terms of safety, complications, morbidity, recurrence, post-op pain and hospital stay.Methods: This was a prospective observational comparative study. Total 50 patients were taken in this study; out of them 25 patients subjected to group A (open repair of inguinal hernia) and 25 patients subjected to group B (laparoscopic repair of inguinal hernia). Postoperatively patients were observed for any complications and followed up one year.Results: Present study shows high incidence of inguinal hernia in males. Mean operative time for open hernia repair group was less than laparoscopic hernia repair group. Time to return to normal work, duration of hospital stay and postoperative pain were less in laparoscopic hernia repair group than open hernia repair group. Out of 25 patients in laparoscopic hernia repair (TEP) 1 patient had recurrence but in open hernia repair group there was no recurrence.Conclusions: Laparoscopic hernia repair is quite safe; it has definite advantages in bilateral and recurrent cases, postoperative pain, early return to normal activities, less postoperative hospital stay and better cosmetic results although it has its own disadvantages in terms of recurrence rate, operative time and cost effectiveness.

Although laparoscopic hernia repair has been shown to be associated with less postoperative pain and an earlier recovery, there is still controversy about its role in hernia surgery. In general, laparoscopy produces less trauma to tissues than open surgery. This has been reflected by the reduced acute phase inflammatory response observed after laparoscopic surgery compared to open surgery in various settings, such as cholecystectomy or hysterectomy. The aim of this study was to evaluate the acute phase response after bilateral hernia repair by comparing the open Stoppa procedure with the laparoscopic totally extraperitoneal prosthetic repair (TEPP). Patients were randomly allocated to either technique after written informed consent was obtained. Measurements were made of complete blood count, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), interleukin-1b (IL-1b), IL-6, and tumor necrosis factor-a (TNF-a) preoperatively and 4, 24, and 48 h postoperatively. VAS pain scores, consumption of analgesics, and delay before resumption of normal activities were also recorded. All the procedures were performed under general anesthesia by or in the presence of the same surgeon. Thirty-nine patients were included: 19 underwent the Stoppa procedure and 20 had a laparoscopic repair. The two groups were well matched for age, sex, ASA score, and preoperative values. The operation took longer (p <0.001) in the group undergoing TEPP. Patients resumed their normal activities earlier (p <0.05) after laparoscopy. In the open group, there was a larger decrease of the lymphocyte count after 4 (p <0.01) and 24 h (p = 0.04); an increased elevation of ESR after 48 h (p = 0.02); a larger increase of IL-6 after 4 (p = 0.05), 24 (p = 0.003), and 48 h (p <0.001); and a larger increase in CRP after 24 (p = 0.05) and 48 h (p = 0.01). There was no morbidity. There was no difference in postoperative IL-1b, TNF-a, total white blood cell count, polymorphonuclear count, VAS for pain, or need for analgesics between the two groups, except on the operative day. The acute phase inflammatory response in clearly more active after the open Stoppa procedure than after TEPP, indicating that the former is associated with increased tissue trauma. This may play a role in the earlier recovery seen after the TEPP procedure.

PurposeHernia repair after recurrence is a challenging procedure, and many approaches have been suggested for it. Total extraperitoneal (TEP) hernia repair should be considered in recurrent hernia. This study was conducted for the purpose of investigating the clinical usefulness of laparoscopic TEP hernia repair for recurrent inguinal hernia.MethodsAmong the 191patients who underwent TEP hernia repair at these authors' center from June 2006 to January 2010, the bilateral-hernia cases and the patients with a history of previous pelvic surgery were excluded. A total of 19 patients (12.5%) were enrolled in the recurrent-inguinal-hernia group (group R), and 133 patients (87.5%) in the primary-hernia group (group P). Data were investigated retrospectively, based on the medical records.ResultsThe mean operation time was 97 minutes in group R and 99 minutes in group P (>0.05). In group R, no operation modality change occurred, and temporary urinary retention was developed in four patients (21.1%). In group P, on the other hand, operation modality change from TEP to the transabdominal preperitoneal approach was necessary in four patients (3%). Additionally, in group P, 30 patients (22.6%) had temporary urinary retention and six (4.5%) had testicular edema. No recurrence was identified during the follow-up period in both groups (mean follow-up period: 15.8 months for group R and 18.0 months for group P).ConclusionLaparoscopic TEP hernia repair seems to be a safe and useful method for correcting recurrent inguinal hernia.

Objective To explore the causes and managements of peritoneal laceration in the laparoscopic totally extraperitoneal (TEP) hernia repair during learning curve. Methods The retrospective cross-sectional study was conducted. The clinical data of 120 patients with inguinal hernia who underwent laparoscopic TEP hernia repair in the Third Affiliated Hospital of Anhui Medical University (98 patients) and Anhui Provincial Hospital (22 patients) during surgeons′ learning curve between February 2012 and January 2017 were collected. Patients underwent laparoscopic TEP hernia repair, meshes were intraoperatively placed and then fixed by medical glue. Observation indicators: (1) intraoperative situations: surgical procedure, operation time, using of mesh, intra-operative peritoneal laceration; (2) postoperative situations: time to anal exsufflation, time for fluid diet intake, occurrence of complications, duration of hospital stay; (3) follow-up: number of patients receiving follow-up, follow-up time, recurrence of hernia during follow-up, pain in inguinal region, intestinal adhesion and obstruction induced abdominal pain, incisional infection. Follow-up using outpatient examination and telephone interview within 10 days postoperatively and using telephone interview at 10 days postoperatively was performed to detect the recurrence of inguinal hernia, pain in inguinal region, intestinal adhesion and obstruction induced abdominal pain and incisional infection up to May 2017. Measurement data with normal distribution were represented as ±s. Results (1) Intraoperative situations: of 120 patients, 112 underwent laparoscopic TEP hernia repair, 5 converted to laparoscopic transabdominal preperitoneal hernia repair and 3 converted to open surgery due to adhesion between hernial sac and surrounding tissues induced bleeding of separation. Total operation time of 120 patients was (71±13)minutes, including (63±7)minutes in 106 patients with unilateral hernia and (79±11)minutes in 14 patients with bilateral hernia. All the patients used intraoperatively meshes of 10.0 cm×15.0 cm and 16.0 cm×10.8 cm. Forty-eight patients had intraoperative peritoneal laceration, peritoneal laceration occurred for reconstruction of preperitoneal space in 10 patients, separation of anterolateral preperitoneal space in 11 patients and improperly operating equipment or hernial sac in 27 patients. Of 48 patients with peritoneal laceration, 40 continued to finish operation through acupuncturing into the abdominal cavity for exsufflation and then received peritoneal suture and repair, including 5 with recurrence of indirect inguinal hernia (receiving tissue repair) undergoing peritoneal repair through opening hernial sac, and 8 intraoperatively converted to other or open surgery. (2) Postoperative situations: time to anal exsufflation and time for fluid diet intake in 120 patients were (18±4)hours and (15±6)hours. Of 120 patients, 14 had postoperative complications, scrotal emphysema of 6 patients disappeared in 24 hours and inguinal and scrotal seroma of 8 patients disappeared after puncture treatment. All the patients were discharged from hospital in 2 days postoperatively. (3) Follow-up: 112 of 120 patients were followed up for 3-65 months, with a median time of 31 months. During follow-up, there was no occurrence of recurrence of hernia, pain in inguinal region, intestinal adhesion and obstruction induced abdominal pain and incisional infection. Conclusion During surgeons′ learning curve, identifying anatomy of the groin clearly, a right way to treat the hernia sac and broken peritoneum in the operation can ensure the smooth completion of the laparoscopic TEP hernia repair.

The need for general anesthesia and the cost and pain due to metal staples required for fixing the mesh are the major reported disadvantages of laparoscopic total extraperitoneal (TEP) hernia repair. We studied the feasibility and results of TEP done under spinal anesthesia with non-fixation of the mesh (SA-NF). This group was compared to TEP done under general anesthesia with non-fixation of the mesh (GA-NF) and repairs done under SA with fixation of the mesh (SA-F). A retrospective analysis was carried out in 675 patients (1,289 hernias) in whom TEP was performed. The recurrence rate, pain scores at 24 h and 1 week, hospital stay, days to resume normal activities, seroma formation, and urinary retention rates were noted. A total of 1,289 TEP repairs (675 patients) were analyzed, with 636 patients (1,220 hernias) in the SA-NF group, 16 patients (27 hernias) in the GA-NF group, and 23 patients (42 hernias) in the SA-F group. Follow up ranged from 13 to 45 months. The recurrence rates, conversion rates, and complications were similar in all three groups. The mean hospital stay, days to resume normal activities, and pain scores were significantly higher in the mesh fixation (SA-F) group. TEP, done under SA and without fixation of the mesh, is safe, feasible, and associated with low recurrence rates. Since this procedure does not have the disadvantages usually attributed to TEP, it can be possibly recommended as a first-line procedure, even for unilateral inguinal hernias. Further studies are needed to substantiate this.

Background: Many different studies have compared open and laparoscopic-endoscopic inguinal hernia repair techniques according to intraoperative and postoperative complications, recurrence rates, postoperative inguinal chronic pain, quality of life, and costs. Most of the researchers have compared these different inguinal hernia repair techniques using a visual analog scale, a short-form survey instrument, or patients’ return-to-normal-activity time, but there is a lack of objective data concerning pelvic function recovery after these procedures. Aim: To evaluate and compare real hip and leg function recovery times after the application of different inguinal hernia repair techniques using hip and leg mobility, strength, and stability testing for the first time. Patients and Methods: This prospective nonrandomized clinical study included 33 male patients aged 18–75 years hospitalized for primary inguinal hernia repair surgery. The patients were divided into two groups: group 1 (Lichtenstein hernia repair) and group 2 (laparoscopic-endoscopic transabdominal preperitoneal/totally extraperitoneal hernia repair). The two groups were compared in terms of intraoperative and postoperative complications, postoperative recovery time, and hip and leg mobility, strength, and stability functional analysis on the first postoperative day as well as 1, 2, and 4 weeks after surgery. Results: A total of 33 patients were included in the study: 13 in the open hernia repair group and 20 in the minimally invasive hernia repair group. There was no significant difference in early and late postoperative complications and recurrence rates. The surgery time and hospital stay were significantly shorter in the laparoscopic-endoscopic hernia repair group. All pelvic functions in the patients who underwent laparoscopic-endoscopic hernia repair recovered 2 or 3 weeks faster than after Lichtenstein repair. Conclusions: Hip and leg mobility, strength, and stability tests are useful to evaluate the recovery time after inguinal hernia repair and could be used as objective tools for estimating recovery after the application of other inguinal hernia repair techniques. Hip and leg mobility, strength, and stability recover faster after minimally invasive inguinal hernia repair. There is no significant difference between the groups in early and late postoperative complications or recurrence rates.

Objectives: Inguinal hernia is the most common hernia and inguinal hernia repair is the most frequently performed operation in gerenal surgery. Hernioplasty by laparoscopy was gradually the standard method for inguinal hernia repair all over the world. The objective of this study is to demonstrate the effectness and safeness of laparoscopic totally extraperitoneal (TEP) hernia repair. Materials and methods: A prospective analysis of patients, admitted for groin hernia and operated by laparoscopic TEP hernia repair, performed between June 2010 and December 2011. Data were collected regarding general characteristics, complication rates, length of hospital stay and the recurrence rate postoperative of this laparoscopic method. Results: 35 patients underwent laparoscopic totally extraperitoneal (TEP) hernia repair with an average age of 51.3±13.8 years (range 31 – 72 years); 5.7% of the inguinal hernias were operated bilaterally, peritoneal laceration was noticed during dissection in 14.3%, there was no injury of the inferior epigastric vessels during dissection. Unilateral hernia had an operative time of 66.52 ± 17.4 minutes (range 45 – 115 minutes) and bilateral hernia took 107.5 minutes (range 95 – 120 minutes). All of these patients in the study were controlled, 5.7% had seroma at the time 3 months postoperative, there were no recurrences during follow-up ranging from 3 – 18 months (average 9.6 months). Conclusions: The laparoscopic (TEP) repair of inguinal hernia is safe and effective. That laparoscopy method should be the gold standard technique in treatment for the repair of inguinal hernias.

Laparoscopic total extraperitoneal (TEP) hernia repair has been confirmed as an effective procedure in several studies but is considered technically demanding. Separating the hernial sac and spermatic cord is difficult when a large sac inguinal hernia is encountered. This study aimed to investigate the feasibility and effectiveness of a combined open and laparoscopic TEP repair of large sac inguinal hernias. From June 2012 to May 2015, laparoscopic TEP (112 cases) and combined open and laparoscopic TEP (COL-TEP) (44 cases) were performed in patients with large sac hernia. There was no clear definition of large sac inguinal hernia; therefore, we defined a large sac as one with the sac base cranial to or over outer ring that could not be easily resected laparoscopically. Using this definition, the laparoscopic TEP group was divided into a small sac TEP (SS-TEP) group (68 cases) and a large sac TEP (LS-TEP) group (44 cases). Direct hernias were included in the SS-TEP group because the hernial sac was easily dissected laparoscopically. The patient demographics, perioperative parameters, complications, and recurrence were compared between the three groups. No significant differences were found between the groups in mean age, gender, body mass index, comorbidities, number of previous laparotomies, or recurrence rate. Compared with the LS-TEP group, both the SS-TEP and COL-TEP groups had a significantly lower surgical duration (51.4±10.9 vs. 32.8±13.1 and 36.2±11.2min, respectively), conversion rate (13.6 vs. 0 and 0%, respectively), and total complication rate (27.3 vs. 13.2 and 11.3%, respectively). The combined technique was safe and effective for repair of large sac inguinal hernias. The combined technique was associated with decreased technical difficulty, surgical duration, and conversion and total complication rates.

Purpose: Laparoendoscopic single-site (LESS) surgery has flourished in several fields of surgery and is viewed as a challenging surgery technique.1 Peritoneal tear during total extraperitoneal (TEP) hernia repair brings longer operation time and higher rate of conversion.2 Although there were several studies published to discuss the efficiency of LESS TEP hernia repair, they did not share the experience in the management and the result in LESS TEP hernia repair while the peritoneal tear happened.3–12 Here, we demonstrate and share our experience in management of the peritoneal tear while performing LESS TEP hernia repair. Materials and Methods: We demonstrate a 64-year-old male without history of operation who was diagnosed with bilateral inguinal hernia and admitted for scheduled LESS TEP hernia repair. A peritoneal tear was found while using the balloon dilator to create the preperitoneal space. The surgical technique is prescribed and explained in detail in the video. From January 2014 to August 2014, there were 30 patients receiving LESS TEP in our study and all are reviewed in this study. Patients were divided into two groups based on the peritoneal tear or not during the LESS TEP hernia repair. Preoperative, intraoperative, and postoperative factors were all recorded. The patients were interviewed at outpatient clinics 1 week after discharge. Results: The total operation time was 90 minutes and there was no recurrence/seroma/hematoma noted during the outpatient clinics follow-up (first week and 3 months after operation). In the retrospective study, demographic data were comparable between the two groups. Eleven of the 30 enrolled patients had a peritoneal injury during operation. The mean operation time was longer in the peritoneal tear group (71.8 ± 27.0 minutes) than in the nonperitoneal tear group (56.2 ± 9.6 minutes) (p = 0.0485). There was no conversion to conventional laparoscopic surgery or open surgery in either group. Postoperative results were comparable between both groups in terms of analgesic requirement, pain score, complications, wound length, and hospital stay. Conclusions: The LESS technique is a feasible and safe technique when peritoneal tear happens during inguinal hernia repair in experienced hands. Although the peritoneal tear usually leads to longer operation time, it did not impair patient's convalescence. No competing financial interests exist. Runtime of video: 6 mins 48 secs

Introduction: Laparoscopic inguinal hernia repair frequently is performed with mechanical fixation of a flat polypropylene mesh. Mechanical fixation is associated with pain syndromes and mesh migration may occur without fixation of flat protheses. An anatomically contoured mesh 3D-Max (3DMAX Mesh/Bard-Davol, France) using no fixation would avoid these problems. The objective of this study is to demonstrate the effectiveness and safeness of laparoscopic totally extraperitoneal (TEP) hernia repair with nonfixation of three-dimensional mesh. Materials and methods: A prospective analysis of patients, admitted for groin hernia type direct and operated by laparoscopic TEP hernia repair with nonfixation of 3D mesh (3DMAX Mesh), performed between June 2010 and June 2015. Data were collected regarding general characteristics, complication rates, length of hospital stay and the recurrence rate postoperative of this method. Results: 36 patients/42 hernias type direct underwent laparoscopic totally extraperitoneal (TEP) repair with nonfixation of 3D mesh. The results show with an average age of 59,5±13,2 years (range 36–85 years); peritoneal laceration was noticed during dissection in 7,1%, there was no injury of the inferior epigastric vessels during dissection. Unilateral hernia had an operative time of 54,5±18,1 minutes (range 30–115 minutes), bilateral hernia was 88,3±24,6 (range 65-120 minutes). All of these patients in the study were controlled with 2,4% had pain post-op at 3 months follow-up postoperative, but at 12 months and 24 months follow-up, there were no complication, no recurrences. Conclusions: The laparoscopic (TEP) repair of inguinal hernia with nonfixation of three-dimensional mesh is safe and effective. Keywords: groin hernia – TEP hernioplasty - laparoscopy
