Outcomes Of Inguinal Hernia Repair Research Articles

Short-term outcomes of inguinal hernia repair in octogenarians and nonagenarians

The objective of this study is to report the 30-day outcomes following inguinal hernia repair in octogenarians (80-89 years of age) and nonagenarians (≥90 years) using a large, prospective, multi-institutional database and to identify the individual risk factors associated with increased morbidity and mortality. Patients aged 80 and above undergoing inguinal hernia repair were identified from the American College of Surgeons' National Surgical Quality Improvement Program (2007-2008). Univariate analysis was performed using chi square, Fisher's exact test and t test. Multivariate logistic regression analysis was carried out to assess factors associated with increased postoperative complications and mortality. Of 2,377 patients above 80 years of age, 226 (9.5 %) were nonagenarians. Men accounted for 81.4 % (1,936) of patients. There were significantly more female patients in the nonagenarian group (29.2 vs. 17.4 %, p < 0.0001). Laparoscopic repair was performed in 210 (9.9 %) patients. Emergency repair was more frequent in nonagenarians than octogenarians (12 vs. 4.4 %, p < 0.0001). The 30-day overall complication rate was significantly increased in nonagenarians compared to octogenarians (6.1 vs. 3.2 %, p = 0.03). Mortality is increased tenfold in elective inguinal hernia repair in nonagenarians compared to octogenarians (3 vs. 0.3 %, p < 0.0005). On multivariate analysis, preoperative variables found to be significantly associated with morbidity included totally dependent functional status, congestive heart failure and emergent nature of procedure, while higher age, emergency repair and open wound are associated with increased mortality. Elective inguinal hernia repair can be safely performed in octogenarians with low morbidity and mortality but is increased in nonagenarians. More vigilant postoperative care is required after emergent hernia repairs due to the increased risk of morbidity and mortality, and effort should be made to electively repair inguinal hernias early in this elderly population.

Laparoscopic inguinal hernia repair in a developing nation: Short-term outcomes in 103 consecutive procedures

Background:There are no published data on the outcomes of inguinal hernia repair from the Anglophone Caribbean. To the best of our knowledge, this is the first report of a series of laparoscopic inguinal hernia repairs from the region.Materials and Methods:Data was extracted from a prospectively maintained database of consecutive trans abdominal pre-peritoneal (TAPP) repairs done between June 1, 2005 and May 30, 2012. Perioperative data collected included patient demographics, hernia type, operative technique, duration of surgery, intra-operative details, morbidity, analgesia requirements, and duration of hospitalization. A telephone survey was also performed to identify late recurrences and complications. Descriptive statistics were generated using Statistical Package for Social Sciences (SPSS) Ver 12.0.Results:There were 103 consecutive TAPP procedures in 88 patients at an average age of 35.4 years ± 12.9 (standard deviation; SD) and average body mass index (BMI) of 28.9 Kg/m2 ± 2.23 (SD). The indications were bilateral (30), recurrent unilateral (24), and primary unilateral (49) inguinal hernias. The mean duration of operation was 68.5 minutes (SD ± 10.4; Range: 55-95; Median 65; Mode 65) minutes for unilateral TAPP and 89 minutes (SD ± 7.61; Range: 80-105; Median 90; Mode 90) for bilateral repairs. Post-operatively, 65/70 patients required ≤1 dose of parenteral opioid analgesia and 74 (84.1%) patients discontinued oral analgesia within 48 hours of operation. Complications were recorded in six (5.8%) cases and a recurrence in one (0.97%) case after a mean follow-up period of 3.2 years (SD ± 1.8; Range: 0.5-7).Conclusion:Laparoscopic inguinal hernia repair is a safe and effective operation in this setting.

Participation of Surgical Residents Does Not Adversely Affect the Outcome of Inguinal Hernia Repair in an Integrated Teaching Program

The Lichtenstein inguinal hernia repair is commonly performed and suitable for teaching basic surgical skills. The objective of this study is to evaluate the feasibility of this procedure for surgical training, particularly in regard to patient outcomes. Retrospective case review after introduction of an integrated teaching program. University teaching hospital. The Lichtenstein inguinal hernia repair is the standard procedure for adult primary unilateral inguinal hernia since 2003 at Jichi Medical University. We introduced an integrated teaching system of lectures, skill training. and videos to teach the skills for Lichtenstein inguinal hernia repair to residents and junior faculty in 2003. Cases were retrospectively divided into 4 groups based on the experience of the operating surgeon; junior residents (PGY 1-2, group A), senior residents (PGY 3-5, group B), junior faculty (PGY 6-10, group C), and senior faculty (PGY 11 or more, group D). Background, perioperative factors, and outcomes were evaluated among the groups. A total of 246 elective inguinal hernia repairs (group A: 136, group B: 49, group C: 42, group D: 19) were performed. There was a significant difference in the frequency of concomitant diseases (p = 0.012) and anticoagulant therapy (p = 0.031). Average operating time was 80.7 ± 24.9, 72.6 ± 20.8, 63.5 ± 22.0, and 54.7 ± 27.9 (min ± SD) in groups A, B, C, and D, respectively, with a significant difference between groups A and D (p < 0.001). No significant differences were observed in estimated blood loss (p = 0.216) or morbidity (p = 0.294). The Lichtenstein inguinal hernia repair can be safely performed by residents and junior faculty with the appropriate supervision of senior faculty without any disadvantage to patients. This integrated teaching program for Lichtenstein inguinal hernia repair is effective and feasible for training residents and junior faculty.

Five-year results of inguinal hernia treatment with the Prolene Hernia System in a regional training hospital

Long-term results of inguinal hernia repair with the Prolene Hernia System (PHS) in our regional training hospital were retrospectively analysed. Research was conducted in an identical cohort of patients previously investigated for short-term results. One-hundred and fifty-eight patients (217 inguinal hernias) treated with the PHS were traced and included. Patients were invited to visit the outpatient clinic for a brief history, physical examination and ultrasound. A quality of life questionnaire was completed by all patients. The primary endpoint was recurrence rate. Testis atrophy, chronic pain and hypaesthesia were secondary endpoints. The mean age of the population (n = 187) was 62.2 years (range 28-92), with a male:female ratio of 15:1 (175:12). The median follow-up was 5.5 years (range 3.9-6.8). One-hundred and forty-five patients visited the outpatient clinic, while 13 patients were included by telephone interview. Twenty-one patients died during follow-up and eight others were lost to follow-up. The resulting follow-up rate was 85% (158/187). In our initial study, we found four recurrences (1.8%) and seven patients with persisting pain (3.2%) after 32 months. During current follow-up, five patients were diagnosed with recurrent herniation (2.3%, 5/217) and only four patients (1.8%) suffered from persisting pain. Three patients (1.4%) were diagnosed with testicular atrophy, while ten patients (4.4%) experienced hypaesthesia. In a regional training hospital, the recurrence rate and long-term complications of patients treated for inguinal hernia with the PHS are acceptable after a follow-up of 5.5 years. The number of patients experiencing persistent pain seems to decrease over time.

Inguinal Hernia Repair: Local or General Anaesthesia?

Specialist hernia centres and public hospitals with a dedicated hernia service (Plymouth Hernia Service) have achieved remarkable results for inguinal hernia repair with the use of local anaesthesia and set the standards for groin hernia surgery. There is minimal data in the literature as to whether such results are reproducible in the National Health Service in the UK. A retrospective analysis of all inguinal hernia repairs performed in one district general hospital over a 9-year period was performed. The outcome measures were type of anaesthesia used, early and late postoperative complications and recurrence. A postal questionnaire survey was conducted to obtain satisfaction rates. In addition, a postal questionnaire survey of consultant surgeons in Wales was performed to determine the use of local anaesthesia and day-case rates for inguinal hernia repair. A total of 577 hernia repairs were performed during the study period. Of these, 369 (64%) repairs were performed under local anaesthesia (LA) and 208 (36%) under general anaesthesia (GA). Day-case repair was achieved in 70% (400) of cases. The day-case rates were significantly higher under LA compared to GA (82.6% versus 42.6%; P < 0.05). Patients operated under LA had lower postoperative analgesic requirements and lower incidence of urinary retention compared with the GA group (P < 0.05). There were 7 (1.2%) recurrences at a median follow-up of 5.1 years (range, 10.3-2.5 years). Postal questionnaire revealed higher satisfaction rates with LA compared to GA repair. Only 15% of surgeons in Wales offer the majority of their patients local anaesthetic repair. The use of LA results in increased day-case rates, lesser postoperative analgesic requirements and fewer micturition problems. The excellent results obtained by specialist hernia centres can be reproduced by district general hospitals by increasing the use of LA to repair inguinal hernias.

Outcome of inguinal hernia repair at two rural hospitals in northern Scotland

Audit of inguinal hernia repair is important in view of the magnitude of the problem and the fact that it is a common operation often performed by surgical trainees. Due to the disparity of the results of various workers with regard to the rate of complications, individual surgeons have been advised to audit their patients' outcomes. Retrospective audit was performed, of all the inguinal hernias repaired between 1997 and 2003 inclusive, at two rural hospitals in northern Scotland, under a single consultant. Data were gathered from a hospital database and by means of postal questionnaire specifically aimed at wound complications, recurrence and chronic groin pain. One hundred and sixty-three inguinal hernias were repaired during this period. One hundred and fifty-eight questionnaires were sent to patients ascertained to be living at the time of audit initiation with a response from 129 (86%). At a mean follow-up of 4.34 years, no recurrences were noted and eight patients complained of chronic groin pain of whom only three (1.5%) were experiencing moderate to severe pain. The results achieved by senior house officers were comparable to those obtained by the senior surgeon. The incidence of recurrence of hernia after open mesh repair of inguinal hernias is very low. Excellent outcomes can be obtained for inguinal hernia even at remote and rural hospitals in the hands of both experienced and trainee surgeons

Does Resident Post Graduate Year Influence the Outcomes of Inguinal Hernia Repair?

We evaluated the effect of the postgraduate medical education level (PGY) of surgery residents on recurrence of inguinal hernia, complications, and operative time. Post hoc analysis was performed on prospectively collected data from a multicenter Veterans Affairs (VA) cooperative study. Men were randomly assigned to open or laparoscopic inguinal hernia repairs with mesh. Surgery residents performed repairs with designated attending surgeons present throughout all procedures. PGY level of the resident was recorded for each procedure. All patients were followed for 2 years for hernia recurrence and complications. PGY levels were grouped as follows: group I = PGY 1 and 2; group II = PGY 3; group III = PGY >/= 4; rates of recurrence, complications and mean operative time were compared. A total of 1983 patients underwent hernia repair. group III residents had significantly lower recurrence rates for open repairs when compared with group I (adjusted odds ratio = 0.24, 95% confidence interval [CI], 0.06, 0.997). The recurrence rate was similar among the groups for laparoscopic repair (P > 0.05) Complication rates were not different for either repair (P > 0.05). Mean operative time was significantly shorter for group III compared with group I for both open (-6.6 minutes; 95% CI, -11.7, -1.5) and laparoscopic repairs (-12.9 minutes; 95% CI, -19.8, -6.0) and between group II and group I for laparoscopic repair (-15.0; 95% CI, -24.3, -5.7). Despite the presence of an attending surgeon, open hernia repairs performed by junior residents were associated with higher recurrence rates than those repaired by senior residents. Lower resident level was associated with increased operative time for both open and laparoscopic repair.

Inguinal hernia repair in Hospital Authority hospitals: The role of laparoscopic hernioplasty

Objective: Two major changes have occurred in inguinal hernia repair during the last two decades: (i) the use of tension‐free mesh repair; and (ii) the application of laparoscopic technique for repair. The aims of the present study were to study: (i) how inguinal hernia repair was carried out; and (ii) the outcome of inguinal hernia repair in Hospital Authority (HA) hospitals.Methodology: This was a retrospective analysis on 8311 elective inguinal hernia repairs performed in 16 HA hospitals from January 2001 to December 2003. The mean age was 63.9 ± 14.2 years, and the male to female ratio was 22.0 : 1.0. Among these, 869 (10.5%) repairs were performed with the laparoscopic approach and 7442 (89.5%) repairs with the open approach. The proportion of laparoscopic hernia repair increased from 8.7% to 12.6%.Results: For open repair, 39% of cases were carried out with regional anaesthesia, 32% with general anaesthesia and 29% with local anaesthesia (LA). Furthermore, mesh repair was used in 88% of the patients. For laparosocpic repair, 98.4% of cases were carried out under general anaesthesia, and all patients had mesh repair using the totally extraperitoneal approach. A significantly higher proportion of bilateral repair and recurrent hernia repair was performed with the laparoscopic approach (P = 0.000). For primary unilateral repair, there was no significant difference in the postoperative length of stay (LOS) and the total LOS between the laparoscopic and the open surgery groups. No difference in LOS was found in recurrent hernia repair between the two groups. With respect to bilateral repair, both the preoperative LOS (P = 0.036) and total LOS (P = 0.039) were shorter in the laparoscopic group. Furthermore, a significantly higher proportion of day‐surgery patients was observed in the laparoscopic group than the open surgery group (21.3%vs 16.9%, P = 0.001). Nevertheless, when only the results of 2003 were analyzed, the postoperative LOS (P = 0.000) and total LOS (P = 0.000) were significantly shorter in the laparoscopic group than the open surgery group. The LOS parameters were significantly shorter in the open surgery LA subgroup compared with the non‐LA subgroup (P = 0.000), and they were not different from those in the laparoscopic group.Conclusions: The open mesh repair is the predominant approach for inguinal hernia repair in HA hospitals. The originally described local anaesthetic approach was under utilized, although it resulted in good outcome. The use of laparoscopic hernia repair is increasing and a learning curve was recently observed with improved outcome.

Protrusion of prosthetic meshes in repair of inguinal hernias

Background Although techniques with prosthetic meshes have improved results of inguinal hernia repair, the problem of recurrence remains. In addition to patient- and surgeon-related causes, protrusion of prosthetic mesh through the hernia defect can be considered as a factor of recurrence. Methods To simulate inguinal hernia, porcine tissue with standardized defects (3, 4, and 5 cm) was used. Nine different meshes (9 cm diameter) were positioned on the defects. In a pressure chamber the depth of protrusion through the defect was assessed. Both sides of each mesh were measured. Protrusion at a pressure representing Valsalva pressure was used for statistical analysis. Results Protrusion, including the incidence of collapse, increased with larger defect sizes. Significant protrusion differences were found between different meshes and occasionally between the 2 sides of the same mesh. Conclusions The differences between the effects of the various meshes emphasize the importance of material characteristics when developing new surgical techniques. The 3 meshes showing least protrusion are considered especially suitable when repairing large defects or when preferring a small mesh when repairing inguinal hernias with a preperitoneal sublay approach.

Lichtenstein inguinal hernia repair in a primary healthcare setting.

Given the generally accepted poor outcome of inguinal hernia repair when using nylon darn, and the recent interest in low-tension mesh repair, an attempt was made to demonstrate the feasibility, outcome and patient perception of providing Lichtenstein inguinal hernia repair, using local anaesthesia, wholly within the primary healthcare sector. A prospective study reviewed clinical outcome and patient perception in 100 adults referred with inguinal hernia only. No selection was made regarding age, sex, American Society of Anesthesiologists status or previous repairs. Recurrence, pain, infection, return to full function and associated complications were assessed at 24 h, 1 and 6 weeks, and 1 year. Local Community Health Councils assessed patient perception. In the first 100 patients (age range 21-83 (mean(s.d.) 60(14.7)) years; 58 of employable age; 92 men; ten recurrent hernias), no recurrences have occurred at 1 year. Infection rate was 3 per cent. Pain was maximal in the first 24-48 h (median visual analogue scale 5, range 0-10) and reduced rapidly (median 1) at 1 week. Mean time to return to work or full normal activity was 8 days. Some 85 operations were performed within 1 month of diagnosis. In all, 86 patients returned the patient satisfaction questionnaire and 98 per cent of these were 'very pleased' with the service. In highly motivated primary healthcare centres, inguinal hernia repair can be undertaken effectively, providing high patient satisfaction, minimal complications and low recurrence rates using the Lichtenstein technique.

Inguinal hernia repair: incidence of elective and emergency surgery, readmission and mortality.

Inguinal hemia repair is one of the most common operations undertaken in routine surgical practice. It generally carries a very low risk of major adverse sequelae. We analysed profiles, separately, for elective and emergency operations to report on the incidence and major adverse outcomes of inguinal hernia repair in a geographically defined population. Age- and sex-specific hospital admission rates, emergency readmission rates within 30 days of discharge, and mortality rates, separately for elective and emergency operations, were calculated for the period 1976-1986 in the Oxford Record Linkage Study (ORLS) area. In all, 30,675 inguinal hernia repairs were performed in the area, an all-ages annual incidence of 13 per 10,000 population. Some 9% of patients underwent operation in an emergency admission. Elective operation rates remained constant over time. Emergency repairs decreased significantly over time in males. Patients who underwent emergency repair were older, had higher emergency readmission rates than those undergoing elective repair, and had significantly elevated postoperative mortality rates. In those who died it was uncommon for inguinal hernia to be recorded on their death certificates. Of the operations, 91% were undertaken on males; age-specific rates were highest in infants and the elderly; and emergency operation rates rose exponentially with age in people > 50 years. The lifetime 'risk' of inguinal hernia repair is high: at currently prevailing rates we estimate it at 27% for men and 3% for women. There is significant elevation of mortality after emergency operations. Elective repair of inguinal hernia should be undertaken soon after the diagnosis is made to minimize the risk of adverse outcomes.
