Prevalence of Surgical Repair for Athletic Pubalgia and Impact on Performance in Football Athletes Participating in the National Football League Combine.

PURPOSE: To examine the prevalence and impact of athletic pubalgia (AP) surgery in elite American football athletes participating in the National Football League (NFL) Combine. METHODS: Results from 1,311 athletes participating in the Combine from 2012 to 2015 were evaluated. Athletes with a history of AP repair were identified using the NFL Combine Database. Athlete history and available imaging was reviewed. NFL performance based on draft status, games played, games started, and current status in the NFL was gathered using publicly available databases. Statistical analysis was performed to detect for significant associations between athlete history and NFL performance in the presence of AP repair and pelvic pathology on postsurgical magnetic resonance imaging (MRI). RESULTS: AP repair was identified in 4.2% (n = 55) of athletes. MRI was performed in 35% (n = 19 of 55) with AP repair, of which 53% (n = 10 of 19) had positive pathology. Athletes with repair were not at risk of playing (P = .87) or starting (P = .45) fewer regular season games, going undrafted (P = .27), or not being on an active NFL roster (P = .51). Compared with athletes with negative imaging findings, positive pathology on MRI did not have a significant impact on games played (P = .74), games started (P = .48), draft status (P = .26), or being on an active roster (P = .74). Offensive linemen (P = .005) and athletes with a history of repair within 1 year of the Combine (P = .03) had a significantly higher risk of possessing positive pathology on MRI. CONCLUSIONS: Athletes with a history of successful AP surgery invited to the NFL Combine and those with persistent pathology on MRI are not at increased risk for diminished performance in the NFL. Offensive linemen and athletes less than 1 year out from surgery have a higher risk for positive MRI findings at the pubic symphysis. LEVEL OF EVIDENCE: Level IV, prognostic study-case series.

Convalescence after laparoscopic inguinal hernia repair: a qualitative systematic review.

BACKGROUND: Duration of convalescence after inguinal hernia repair is of major socio-economic interest and an often reported outcome measure. The primary aim was to perform a critical analysis of duration of convalescence from work and activity and secondary to identify risk factors for unexpected prolonged convalescence after laparoscopic inguinal hernia repair. METHODS: A qualitative systematic review was conducted. PubMed, Embase and the Cochrane database were searched for trials reporting convalescence after laparoscopic inguinal hernia repair in the period from January 1990 to January 2016. Furthermore, snowball search was performed in reference lists of identified articles. Randomized controlled trials and prospective comparative or non-comparative trials of high quality were included. Trials with ≥100 patients, >18 years of age and manuscripts in English were included. Scoring systems were used for assessment of quality. RESULTS: The literature search identified 1039 papers. Thirty-four trials were included in the final review including 14,273 patients. There was overall a large variation in duration of convalescence. Trials using non-restrictive recommendations of 1-2 days or "as soon as possible to return to all activities" reported overall a shorter duration of convalescence compared with trials not using recommendations for convalescence. Strenuous physical activity at work, strenuous leisure activity and patients with expectations of a prolonged period of convalescence may be risk factors for prolonged convalescence extending more than a few days after laparoscopic inguinal hernia repair. CONCLUSIONS: Patients should be recommended a duration of 1-2 days of convalescence after laparoscopic inguinal hernia repair. Short and non-restrictive recommendations may reduce duration of convalescence without increasing risk of pain, complications or recurrence rate.

[LAPAROSCOPIC HERNIOPLASTY IN INCARCERATED INGUINAL HERNIAS].

The results of laparoscopic hernioplasty, using TAPP method and operation of Lichtenstein in 80 patients, suffering incarcerated inguinal hernia, were analyzed. While achievement of similar good and excellent immediate and late results, laparoscopic procedure has several advantages and may be used as a method of choice for treatment of inguinal hernia.

Meta-analysis of randomized controlled trials comparing Lichtenstein and totally extraperitoneal laparoscopic hernioplasty in treatment of inguinal hernias.

BACKGROUND: Finding the optimal approach to repair an inguinal hernia is controversial. Therefore, for the scientific evaluation of the total extraperitoneal (TEP) and Lichtenstein mesh techniques for the repair of inguinal hernia, meta-analyses of randomized controlled trials are necessary. METHODS: A complete literature search was conducted in the Cochrane Controlled Trials Register Databases, Pubmed, Embase, International Scientific Institute databases, and Chinese Biomedical Literature Database in various languages. RESULTS: Randomized controlled trials (13), including 3279 patients, were retrieved from the electronic databases. The Lichtenstein group was associated with a shorter operating time; however, results show that TEP repair enabled patients a shorter time to return to work, less chronic pain compared with Lichtenstein operation. There was no significant difference in seromas, wound infections, or neuralgia. There are no statistically significant difference in terms of hernia recurrence when the follow-up time is ≤3 y. When follow-up time is >3 y, TEP repair shows a higher recurrence rate compared with Lichtenstein repairs. CONCLUSIONS: There was insufficient evidence to determine the greater effectiveness between TEP and Lichtenstein mesh techniques. In future research, it is necessary for subgroup analyses of unilateral primary hernias, recurrent hernias, and simultaneous bilateral repair to be conducted to define the indications for the TEP approach.

Assessing the performance of the EQ-VAS in the NHS PROMs programme.

OBJECTIVES: The study aims to increase knowledge about the performance of the EuroQol-visual analogue scales (EQ-VAS) in the UK NHS patient-reported outcome measures (PROMs) programme, which covers groin hernia, hip and knee replacement and varicose vein surgery, and make suggestions for improved collection, coding and analysis of data. METHODS: Four hundred scanned images of matched before-and-after EQ-VAS PROMs responses were selected at random. These were classified according to the different ways in which they were completed. Patient-level PROMs programme data linked to Hospital Episode Statistics for all patients from April 2009 to February 2011 were used to analyse the relationship between the EQ-VAS and the EQ-5D profile, index-weighted profile and condition-specific instruments. The linked PROMs and HES data comprise 331,951 anonymised patient records. RESULTS: A large majority (95 %) of EQ-VAS responses were completed in an unambiguous way, but only a minority (45 %) conformed strictly to the instructions given, posing challenges for data coding. The EQ-VAS data have a predictable and consistent relationship with the EQ-5D profile, although the correlations between the EQ-VAS and other measures of patient-reported health, both before and after surgery and in the change between them, are weak. CONCLUSIONS: EQ-VAS data might be improved by providing better guidance on collection and coding. It is argued that the observed differences in results from EQ-VAS and other measures of health reflect the fact that it measures a broader underlying construct of health, arguably providing a means of summarising overall health that is closer to the patient's perspective.

Radially expanding laparoscopic trocar ports significantly reduce postoperative pain in all age groups.

BACKGROUND: Trocar entry points have been identified as a significant source of pain after laparoscopic surgery. This is particularly true of the larger 12-mm ports that require deep fascial closure to avoid port-site herniation. We investigated whether using radially expanding trocars not requiring fascial closure compared to conventional cutting trocars for the 12-mm port in transabdominal preperitoneal (TAPP) hernia repairs had any effect on postoperative analgesic requirements and return to work or normal activity. METHODS: The number of days analgesia was required postoperatively and the number of days taken to return to normal activity was recorded for 143 consecutive patients who underwent TAPP hernia repair by a single experienced laparoscopic surgeon. Exactly the same operative technique was used in these patients with the exception of the 12-mm port site entry. In group 1 (104 patients), a conventional cutting trocar was used requiring deep fascial closure. In group 2 (39 patients), a radially expanding trocar was used and the fascial defect was not closed. RESULTS: Analgesia was required for an average of 10.5 days in group 1 and 2.4 days in group 2 (P < 0.001). The average time to return to work or to normal activity was 23.4 days in group 1 and 15.6 days in group 2 (P = 0.004). There was no significant difference between the two groups with respect to the patients' age, sex, or operating time. CONCLUSION: Using the laparoscopic TAPP hernia repair as a standardised operation, changing from 12-mm fascial port closure to a technique that uses port dilation (not requiring a potentially "tight" deeper fascial closure) in a similar group of patients shows that there is a significant reduction in postoperative analgesic requirement and an earlier return to productive work or normal lifestyle. Perhaps dilating ports should replace those larger 10-, 12-, and 15-mm ports that require deeper sutures in all laparoscopic surgical operations.

Digital evaluation of the muscle functions of the lower extremities among inguinal hernia patients treated using three different surgical techniques: a prospective randomized study.

PURPOSE: An inguinal hernia is a common pathology that can be treated using several different surgical procedures. Although there have been many studies comparing the clinical results of these techniques, there has so far been no digital analysis of the alterations developing secondary to pain with regard to the muscle functions of the lower extremities. This prospective randomized trial was designed to compare this aspect for subjects treated using the laparoscopic techniques and those treated using the conventional method. METHODS: A total of 75 patients, 25 of whom who had undergone hernia repair using the total extraperitoneal technique, 25 of whom who had undergone repair using the transabdominal preperitoneal technique, and 25 who had undergone repair using the Prolene mesh graft technique, were evaluated preoperatively and on the third postoperative day by isometric and isokinetic measurements, the visual analog score (VAS), the necessity of postoperative analgesia, complications, and the time that had elapsed before returning to work, and these results were recorded. RESULTS: Hernia repair using the conventional method led to an average of 3 times more muscle function loss compared with the laparoscopic techniques, and this difference was shown to be statistically significant. The VAS, postoperative complications, and time elapsed before returning to work were lower for laparoscopic surgeries and also were compatible with the findings described in the previous literature. CONCLUSIONS: Use of a digital environment with numerical parameters and measurements recorded using a dynamometer demonstrated that in the early postoperative period and on the third postoperative day, open surgery causes more functional loss in the lower extremities than laparoscopic methods. Therefore, surgeons should use laparoscopic methods whenever possible to reduce both pain and loss of muscle function.

Validity, reliability and responsiveness of patient-reported outcome questionnaires when assessing hip and groin disability: a systematic review.

BACKGROUND: Novel treatment interventions are advancing rapidly in the management of hip and groin disability in the physically active young to middle-aged population. OBJECTIVE: To recommend the most suitable patient-reported outcome (PRO) questionnaires for the assessment of hip and groin disability based on a systematic review of evidence of validity, reliability and responsiveness of these instruments. METHODS: MEDLINE, EMBASE, CINAHL, Cochrane Central Register of Controlled Trials, PsycINFO, SportsDiscus and Web of Science were all searched up to January 2009. Two reviewers independently rated measurement properties of the PRO questionnaires in the included studies, according to a standardised criteria list. RESULTS: The computerised search identified 2737 publications. Forty-one publications investigating measurement properties of PRO questionnaires assessing hip or groin disability were included in the study. Twelve different questionnaires designed for patients with hip disability and one questionnaire for patients with groin disability were identified. Hip dysfunction and Osteoarthritis Outcome Score (HOOS) contains adequate measurement qualities to evaluate patients with hip osteoarthritis (OA) or total hip replacement (THR). Hip Outcome Score (HOS) is the best available questionnaire for evaluating hip arthroscopy, but the Inguinal Pain Questionnaire, the only identified questionnaire evaluating groin disability, does not contain adequate measurement qualities. CONCLUSIONS: HOOS is recommended for evaluating patients with hip OA undergoing non-surgical treatment and surgical interventions such as THR. HOS is recommended for evaluating patients undergoing hip arthroscopy. Current and new PRO questionnaires should also be evaluated in younger patients (age <50) with hip and/or groin disability, including surgical and non-surgical patients.

Analysis of exercise tolerance on the basis of six-minute walk test - 6MWT and Borg RPE scale in men with inguinal hernia before and after Lichtenstein repair.

<b>Introduction:</b> Assessment of exercise tolerance (ET) plays an important role in qualifications for treatment and rehabilitation. <br><b>Aim: </b>The aim of the study was to assess ET in patients before and after inguinal hernia operations with Lichtenstein method. <br><b>Material and methods:</b> The cohort study included men with inguinal hernia divided into the study group (SG) (n = 50) and control (CG) (n = 50) undergone the Lichtenstein surgery. Patients from the SG met the criterion of coexistence of cardiovascular and respiratory diseases. Day before and on the second day after surgery, patients performed 6MWT and subjectively rate the exertion according to Borg- RPE- Scale (before, immediately after and 10 minutes after the test). 6MWT distance, Borg scale ratings were analysed. On the second day after surgery 66% of patients from the SG and 58% from the CG did not complete the test. Patients from the SG before (500,07 ± 40,38 m) and on the second day after surgery (243,46 ± 18,18 m) achieved shorter distances compared to the CG (565,93 ± 20,41 m; 249,47 ± 26,66 m), p < 0,001 i p = 0,481. A statistically significant negative correlation between 6MWT distance before surgery and age of the patients was confirmed. Patients who did not develop complications achieved significantly longer distances on admission (p = 0,003 for SG, p = 0,004 for CG). For 6MWT before surgery and 2 days after surgery, patients from the SG showed a significantly higher level of fatigue compared to the CG after the test (before: p = 0,001, after: p = 0,001). Patients form the SG often discontinued 6MWT and less tolerated effort compared to the CG. Hence, 6MWT is useful tool for ascertaining physical capacity and ET.

Sports hernias: a systematic literature review.

This review summarises the existing knowledge about pathogenesis, differential diagnosis, conservative treatment, surgery and post-surgical rehabilitation of sports hernias. Sports hernias occur more often in men, usually during athletic activities that involve cutting, pivoting, kicking and sharp turns, such as those that occur during soccer, ice hockey or football. Sports hernias generally present an insidious onset, but with focused questioning a specific inciting incident may be identified. The likely causative factor is posterior inguinal wall weakening from excessive or high repetition shear forces applied through the pelvic attachments of poorly balanced hip adductor and abdominal muscle activation. There is currently no consensus as to what specifically constitutes this diagnosis. As it can be difficult to make a definitive diagnosis based on conventional physical examination, other methods, such as MRI and diagnostic ultrasonography are often used, primarily to exclude other conditions. Surgery seems to be more effective than conservative treatment, and laparoscopic techniques generally enable a quicker recovery time than open repair. However, in addition to better descriptions of surgical anatomy and procedures and conservative and post-surgical rehabilitation, well-designed research studies are needed, which include more detailed serial patient outcome measurements in addition to basing success solely on return to sports activity timing. Only with this information will we better understand sports hernia pathogenesis, verify superior surgical approaches, develop evidence-based screening and prevention strategies, and more effectively direct both conservative and post-surgical rehabilitation.

Proposed algorithm for the management of athletes with athletic pubalgia (sports hernia): a case series.

STUDY DESIGN: A case series of 6 athletes with a suspected sports hernia. BACKGROUND: Groin pain in athletes is common, and 1 source of groin pain is athletic pubalgia, or a sports hernia. Description of this condition and its management is scarce in the physical therapy literature. The purpose of this case series is to describe a conservative approach to treating athletes with a likely sports hernia and to provide physical therapists with an algorithm for managing athletes with this dysfunction. CASE DESCRIPTION: Six collegiate athletes (age range, 19-22 years; 4 males, 2 females) with a physician diagnosis of groin pain secondary to possible/probable sports hernia were referred to physical therapy. A method of evaluation was constructed and a cluster of 5 key findings indicative of a sports hernia is presented. The athletes were managed according to a proposed algorithm and received physical therapy consisting of soft tissue and joint mobilization/manipulation, neuromuscular re-education, manual stretching, and therapeutic exercise. OUTCOMES: Three of the athletes received conservative intervention and were able to fully return to sport after a mean of 7.7 sessions of physical therapy. The other 3 athletes reached this outcome after surgical repair and a mean of 6.7 sessions of physical therapy. DISCUSSION: Conservative management including manual therapy appears to be a viable option in the management of athletes with a sports hernia. Follow-up randomized clinical trials should be performed to further investigate the effectiveness of conservative rehabilitation compared to a homogeneous group of patients undergoing surgical repair for this condition. LEVEL OF EVIDENCE: Therapy, level 4.

Postoperative Rehabilitation May Reduce the Risk of Readmission After Groin Hernia Repair.

Thirty-day readmission after surgery has been proposed as a quality-of-care indicator. We explored the effect of postoperative rehabilitation on readmission risk after groin hernia repair. We used the French National Discharge Database to identify all index hospitalizations for groin hernia repair in 2011. Readmissions within 30 days of discharge were clinically classified in terms of their relationship to the index stay. We used logistic regression to adjust the risk of readmission for patient, procedure and hospital factors. Among 122,952 index hospitalizations for inguinal hernia repair, 3,357 (2.7%) related 30-day readmissions were recorded. Reiterated analyses indicated that readmission risk was consistently associated with patient complexity: age (per year after 60 years, OR 1.03, 95% CI 1.02-1.03, P < 0.001), hospitalization within the previous year (OR 1.56, 95% CI 1.44-1.69, P < 0.001), and increasing severity and combination of co-morbidities. Postoperative rehabilitation was identified as a protective factor (OR 0.56, 95% CI 0.46-0.69, P < 0.001). Older patients and those with greater comorbidity are at elevated risk of readmission after inguinal hernia repair. Postoperative rehabilitation may reduce this risk. Further studies are warranted to confirm the protective effect of postoperative rehabilitation.

Dispositional pessimism predicts delayed return to normal activities after inguinal hernia operation.

BACKGROUND: The traditional outcome measure to assess effectiveness of inguinal hernia operation was recurrence. Open mesh repair has reduced recurrence rates and attention is now turning to outcomes other than recurrence. The factors influencing the large variation in reported times of resumption of normal activities after inguinal hernia repair are many and diverse. The human factors influencing resumption of normal activity are rarely reported. METHODS: We undertook a prospective study of 206 patients undergoing primary inguinal hernia repair in an ambulatory setting in a public hospital to ascertain whether dispositional outlook on life affected resumption of normal activity after hernia repair. Outlook on life was assessed using the life orientation test. An independent observer assessed the patients preoperatively and determined timing of resumption of normal activities. RESULTS: Regression analysis showed a highly significant relationship between delayed return to normal activity and dispositional pessimism (P =.0004). DISCUSSION: Dispositional pessimism correlates strongly with delayed return to normal activities. Further studies of this kind will help to elucidate the human factors that affect recovery after operation. Studies which use return to normal activities as a measure of the outcome of a surgical technique should include an assessment of the patient's preoperative outlook on life. Surgeons should consider the personality of the patient presenting for groin hernia repair and may wish to tailor their counseling accordingly.

Return to work after inguinal hernia repair.

BACKGROUND: There is much variation in the time when a patient returns to work after inguinal hernia repair. Most surgical research has focused on the type of operation performed, but other factors may be equally or more important. This study attempted to identify these factors. METHODS: We prospectively studied the return to work after inguinal hernia repair in a convenience sample of 235 patients who were operated on by one surgical group. Ninety-three of these subjects, who were working and had complete data, were included in this analysis. Data were gathered through personal interviews, written surveys, and medical record reviews. The main outcome measures were actual and expected return to work. RESULTS: Primary tissue repair was done in 94% of the patients. The mean age was 49 years; 90% were male. The expected return to work was 10 days; the actual mean return to work after operation was 12 days (median, 7 days; range, 2 to 60 days) and was unrelated to preoperative functional status. Bivariate analysis showed that age, educational level, income level, occupation, symptoms of depression, and the expected return to work accounted for 61% of the variation in actual return to work. CONCLUSIONS: Factors other than operative technique, including patient expectations, are strongly associated with return to work after inguinal hernia repair. Depression significantly delayed return to work. More research is needed to understand how expectations are formed and how decisions are made regarding return to work, and whether these can and/or should be influenced by surgeons, employers, or others to promote earlier return to work.

Laparoscopic or open inguinal herniorrhaphy? A randomized prospective trial.

OBJECTIVE: To determine whether transabdominal preperitoneal laparoscopic hernia repair can equal or surpass an established open method at an acceptable cost. DESIGN: A randomized, prospective comparison with a follow-up of 7 to 18 months (median, 10 months; planned, 5 years). SETTING: Health maintenance organization hospital. PATIENTS: One hundred patients between 20 and 70 years of age were randomized. No patient withdrew from the study after randomization. INTERVENTIONS: Transabdominal preperitoneal laparoscopic and open tension-free repairs using a polypropylene mesh. MAIN OUTCOME MEASURES: Operative and discharge times, costs, recovery, and morbidity. "Return to work" was supplemented by a performance assessment using a panel of exercises. RESULTS: Operative and hospitalization times were not significantly different between the two types of repair. Patients with laparoscopic unilateral repairs returned to work faster (9 vs 17 days). At 1 week postoperatively, performance of straight-leg raises correlated well with time to return to work for patients with strenuous jobs. The laparoscopic repair was more expensive than the open approach ($3093 vs $2494). CONCLUSIONS: Laparoscopic transabdominal preperitoneal hernia repair can be accomplished with operative and hospitalization times and a short-term recurrence rate similar to those of an established open technique. Perioperative exercise testing may be an important adjunct to return to work in the comparison of methods.

Postoperative course after inguinal herniorrhaphy. A case-controlled comparison of patients receiving workers' compensation vs patients with commercial insurance.

OBJECTIVE: To confirm our observation that patients with work-related hernias, when compared with self-employed patients, had longer recovery times and prolonged pain after hernia repairs, we reviewed our recent experience in a series of patients undergoing inguinal hernia repairs. DESIGN: The study design was matched retrospective case-control. Each patient receiving workers' compensation was age and sex matched with a control patient with commercial insurance whose repair was done during the same year. SETTING: All inguinal herniorrhaphies were performed at a single clinic by one of seven surgeons. PATIENTS: Twenty-two consecutive patients receiving workers' compensation and 22 patients with commercial insurance were studied. MAIN OUTCOME MEASURES: The postoperative courses in 22 consecutive patients with workers' compensation were compared with those in 22 control patients with commercial insurance. The principal factors compared were indications for surgery, type of hernia, surgical repair performed, the duration of postoperative pain, and the number of days off daily work. RESULTS: The average age in both groups was 46 years. Hernias in the workers' compensation group were more frequently symptomatic. The duration of postoperative pain (mean +/- SE) was 111.0 +/- 42.2 days for patients with workers' compensation and 17.8 +/- 7.9 days for patients with commercial insurance (P < .05). The number of days off work (mean +/- SE) was 33.5 +/- 4.6 days for patients receiving workers' compensation and 12.6 +/- 2.3 days for patients with commercial insurance (P < .001). CONCLUSIONS: We believe our results confirm the observation that type of insurance coverage influences post-operative recovery time after inguinal herniorrhaphy. Other studies measuring a patient's outcome after surgical procedures such as herniorrhaphy should include type of insurance coverage as a factor that might affect early return to work. Using multivariate analysis, the only variable independently affecting the duration of pain after hernia repair was the type of insurance coverage (P < .005).

Short-term outcomes in open vs. laparoscopic herniorrhaphy: confounding impact of worker's compensation on convalescence.

Over a 28-month period, 123 patients with a unilateral inguinal hernia were recruited into a randomized controlled trial comparing open herniorrhaphy (OH) to laparoscopic inguinal herniorrhaphy (LH). The primary end point was duration of convalescence. Sixty-five patients underwent OH and 58 underwent LH. Both groups were well matched for all baseline parameters, although LH patients anticipated a shorter convalescence than OH patients (14.3 +/- 9.4 days vs. 18.5 +/- 10.8 days; P = 0.021). The median duration of hospital stay was one day in both groups. No difference was observed in the duration of convalescence (LH 9.8 +/- 7.4 days; OH 11.6 +/- 7. 7 days) across groups. However, when the data were analyzed after removing patients receiving disability ("worker's") compensation (21 patients), patients undergoing LH recovered on average 3 days faster (LH 7.8 +/- 5.6 days; OH 10.9 +/- 7.5 days; P = 0.02). Patients not receiving worker's compensation appear to have a shorter convalescence after LH compared to OH. Disability compensation is a major confounding variable in determining convalescence and needs to be controlled for in any future trial design.

Occupational rehabilitation following open mesh surgical repair of an inguinal hernia.

BACKGROUND AND PURPOSE: The purpose of this case report is to describe an occupational rehabilitation program for a person whose work-related inguinal hernia was surgically repaired. CASE DESCRIPTION: A 35-year-old baggage service attendant acquired an inguinal hernia while lifting at work. Postoperatively, the patient had discomfort in the groin, weakness of the lower extremities and trunk, limited ability to walk, and a decreased ability to work due to impaired lifting tolerance. OUTCOMES: Following postoperative rehabilitation, the patient was able to return to full-time, full-duty work. DISCUSSION: This case report describes occupational rehabilitation as a method to treat patients with work-related inguinal hernias following surgical repair.

Laparoscopic hernia repair enhances early return of physical work capacity.

Several researchers have documented less postoperative pain and a quicker return to daily activities after laparoscopic herniorrhaphy. However, little objective data that validates this hypothesis exists. This study compares the rate of postoperative physical work capacity with return to preoperative levels, which is measured by a standard treadmill test in patients who underwent laparoscopic and conventional open hernia repair. Patients completed a 6-minute walking test preoperatively and 1 week postoperatively using a nonmotorized treadmill. The distance walked was recorded. If the distance that a patient achieved at 1 week was not within 0.02 miles of the preoperative values of the patient, the patient was asked to return at 1 month for repeat testing. Patients were enrolled prospectively in this study from October 1997 to February 1999. Sixty-six patients participated in the study (27 laparoscopic herniorrhaphies and 39 open herniorrhaphies were performed). There was no significant difference in age, body mass index, or preoperative distance achieved among the two groups. At 1 week, patients who underwent laparoscopic repair demonstrated a mean increase of 18 meters from preoperative distance (P = 0.07). In the open group, patients demonstrated a mean decrease of 90 meters at 1 week (P = 0.001). The change in distance at 1 week between the laparoscopic and the open groups was statistically significant (P = 0.001). However, at 1 month, there was no significant difference among the two groups. Measured using treadmill walking, laparoscopic hernia repair seems to offer an early advantage to open repair in return-to-physical-work capacity.

A prospective study of bilateral inguinal hernia repair.

A prospective study of outcome after inguinal hernia repair in patients undergoing simultaneous repair of bilateral hernias (n = 31), sequential repair of bilateral hernias (n = 5), and unilateral hernia repair (n = 75) is reported. There were no differences in wound complications, post-operative respiratory complications, or other adverse effects in the three groups. Operating time was similar in the unilateral and bilateral simultaneous repairs (median 55 min), but was longer (100 min) for the combination of two sequential repairs. Hospital stay was shortest for patients undergoing unilateral repair (2 days) but was less with bilateral simultaneous repair (4 days) than after two sequential repairs (total of 6 days). There were 12 (11%) wound complications of which five (5%) were infections. There was no difference in complication rate between unilateral and bilateral hernia repair. Postoperative recovery was assessed prospectively and was recorded at 1 month. There was no difference between unilateral and bilateral simultaneous repairs in the number of days before the patient was able to climb stairs easily, drive a car or return to work. The duration of the requirement for analgesia was similar in each group. We conclude that bilateral simultaneous hernia repair can be carried out with no greater morbidity than a unilateral repair, and the return to normal activity is as rapid. Bilateral hernias should be repaired simultaneously rather than sequentially.
