Inguinal hernia repair: are ASA grades 3 and 4 patients suitable for day case hernia repair?

Outpatient Surgery and Unplanned Overnight Admission in Bilateral Inguinal Hernia Repair: A Population-based Study

PURPOSE

The use of outpatient surgery in inguinal hernia is heterogeneous despite clinical recommendations. This study aimed to analyze the utilization trend of outpatient surgery for bilateral inguinal hernia repair (BHIR) in Spain and identify the factors associated with outpatient surgery choice and unplanned overnight admission.

METHODS

A retrospective observational study of patients undergoing BIHR from 2016 to 2021 was conducted. The clinical-administrative database of the Spanish Ministry of Health RAE-CMBD was used. Patient characteristics undergoing outpatient and inpatient surgery were compared. A multivariable logistic regression analysis was performed to identify factors associated with outpatient surgery choice and unplanned overnight admission.

RESULTS

A total of 30,940 RHIBs were performed; 63% were inpatient surgery, and 37% were outpatient surgery. The rate of outpatient surgery increased from 30% in 2016 to 41% in 2021 (p < 0.001). Higher rates of outpatient surgery were observed across hospitals with a higher number of cases per year (p < 0.001). Factors associated with outpatient surgery choice were: age under 65 years (OR: 2.01, 95% CI: 1.92-2.11), hospital volume (OR: 1.59, 95% CI: 1.47-1.72), primary hernia (OR: 1.89, 95% CI: 1.71-2.08), and laparoscopic surgery (OR: 1.47, 95% CI: 1.39-1.56). Comorbidities were negatively associated with outpatient surgery. Open surgery was associated (OR: 1.26, 95% CI: 1.09-1.47) with unplanned overnight admission.

CONCLUSIONS

Outpatient surgery for BHIR has increased in recent years but is still low. Older age and comorbidities were associated with lower rates of outpatient surgery. However, the laparoscopic repair was associated with increased outpatient surgery and lower unplanned overnight admission.

Day-case and in-patient elective inguinal hernia repair surgery across England: an observational study of variation and outcomes

PURPOSE

Elective primary inguinal hernia repair surgery is increasingly being conducted as a day-case procedure. However, in England there is evidence of wide variation in day-case rates across hospitals. Reducing the extent of this variation has the potential to support more efficient use of resources (e.g., clinician time, hospital beds) and help the recovery of elective surgical activity following the COVID-19 pandemic. The aims of this study were to explore the extent of variation in day-case rates across healthcare providers in England and to evaluate the safety of day-case elective primary inguinal hernia repair surgery.

METHODS

This was an exploratory, retrospective analysis of observational data from the Hospital Episode Statistics data set for England. All patients aged ≥ 17 years undergoing a first elective inguinal hernia repair between 1st April 2014 and 31st March 2022 were identified. The exposure of interest was day-case or in-patient stay, and the primary outcome of interest was 30-day emergency readmission with an overnight stay. For reporting, providers were aggregated to an Integrated Care Board (ICB) level.

RESULTS

A total of 413,059 elective primary inguinal hernia repairs were identified over the 8-year study period. Of these, 326,833 (79.1%) were day-case procedures. During the most recent financial year (2021-22), the highest day-case rate for an ICB was 93.8% and the lowest 66.1%. After adjusting for covariates, day-case surgery was associated with significantly lower rates of 30-day emergency readmission (odds ratio (OR) 0.61, 95% confidence interval (CI) 0.58-0.64, p < 0.001) and for the secondary outcomes 180-day mortality and haemorrhage, infection and pain at 30-day post-discharge. Rates of 30-day emergency readmission were significantly lower in ICBs with high rates of day-case surgery (OR 0.84, 95% CI 0.74-0.96, p < 0.001) than in ICBs with low rates of day-case surgery, although rates of post-procedural haemorrhage within 30 days of discharge were significantly higher in trusts with high day-case rates (OR 1.20, 95% CI 1.04-1.40, p = 0.015).

CONCLUSIONS

For the outcomes studied, we found no consistent evidence that day-case elective inguinal hernia repair was unsafe for selected patients. Currently, there is substantial variation between ICBs in terms of delivering day-case surgery. Reducing this variability may help address the current pressures on the NHS in elective surgery.

The feasibility and safety of laparoscopic inguinal hernia repair as a 24-h day surgery for patients aged 80 years and older: a retrospective cohort study

INTRODUCTION

As the proportion of aging adults increases and inguinal hernia repair becomes increasingly popular as a day surgery, the demand for laparoscopic inguinal hernia repair as a day surgery is increasing among patients aged 80 years and older. Relevant research needs to be completed, so we aimed to evaluate laparoscopic inguinal hernia repair as a 24-h day surgery for this group of patients.

METHODS

In this retrospective cohort study, we utilized propensity score matching to analyze the data of patients who underwent laparoscopic inguinal hernia repair at a day surgery center between January 1, 2019, and March 1, 2022. Patients were divided into ≥ 80 years old and < 80 years old groups. We compared the perioperative laboratory results, perioperative outcomes, and 1-year complications between the two groups.

RESULT

A total of 554 patients were included in the study. After propensity score matching, 292 patients were included in the matched cohort (98 patients in the ≥ 80 years old group and 194 patients in the < 80 years old group). During hospitalization, there were significant differences in ASA classification, Caprini score, length of hospital stays, risk of thrombosis, and delayed discharge rate. No significant difference was found in the incidence of total postoperative complications between the two groups at the 1-year follow-up (HR: 0.96, 95% CI 0.36-2.54, P = 0.96).

CONCLUSION

In our study, LIHR as a 24-h day surgery was safe and effective for patients over 80 years old. However, to reduce the rate of delayed discharge, cautious perioperative evaluation is necessary.

Implementing an outpatient surgical management in moderated-high risk patients with groin hernia repair

PURPOSE

There is a growing trend to expand Ambulatory Surgery (AS) criteria in abdominal wall surgery. No Admission (NOADS) circuit. The present study aimed to assess the impact of classification criteria on postoperative results and hospital stays in a NOADS versus a conventional admission circuit to throw some light on surgical circuit inclusion.

METHODS

A retrospective analysis of a prospective;y maintained database was performed comparing groin hernia's interventions in a NOADS vs Admission circuit in our center in 2018-2021. A multiple regression predictive model followed by a retrospective retest were dessigned to assess the impact of each criterion on hospital stay. In total, 743 patients were included, 399 in the Admission circuit (ADC) and 344 in NOADS circuit (NOADS).

RESULTS

There were no statistical differences in complication or readmission rates (p = 0.343 and p = 0.563), nevertheless, a shorter hospital stay was observed in NOADS (p = 0.000). A hierarchical multiple regression predictive model proposed two opposite scenarios. The best scenario, not likely to need admission, was a female patient operated via the laparoscopic approach of a unilateral primary hernia (Estimated Postoperative Stay: 0.049 days). The worst scenario, likely to need admission, was a male patient operated via the open approach of a bilateral and recurrent hernia (Estimated Postoperative Stay: 1.505 Days).

CONCLUSION

Groin hernia patients could safely benefit from a No Admission (NOADS) circuit. Our model could be useful for surgical circuit decision-making, especially for best/worst scenarios.

[Inguinal hernia repair in TAPP technique in a day-case surgery setting - at what price?]

BACKGROUND

TAPP surgery can be considered as a gold standard in inguinal hernia repair. Patients benefit of a faster reconvalescence and less pain compared to other techniques. TAPP surgery in Germany is performed in an in-patient setting routinely. However, according to European guidelines, inguinal hernia surgery should be considered as day-case surgery whenever possible.

OBJECTIVES

The safety of day-case surgery was examined in relation to postoperative pain, complications, comorbidities, recurrent inguinal hernia and bilateral procedures.

MATERIAL AND METHODS

In a retrospective, monocentric study we analyzed 522 elective inguinal hernia repairs using TAPP technique in a specialized hernia center. Supplemental data from Herniamed registry is analyzed.

RESULTS

Parts of the procedures should be performed in an in-patient setting, whereas a much larger number of cases should be carried out as day-case surgeries. Logistic regression analyses show that "age", "bilateral procedures" and "comorbidities" affect the complication rate. "Age" and "recurrent inguinal hernia" are risk factors for an increased need for analgetic medication. Furthermore, we present an actual distribution of day-case vs. in-patient surgeries in inguinal hernia repair based on data from the Herniamed registry.

CONCLUSION

A much larger part of procedures could safely be carried out as day-case surgeries. Based on a false incentive there is an incorrect steering in the German health system. These procedures cannot be carried out covering the costs as day-surgery cases. If there is no reevaluation of the proceeds of these procedures in a day-case surgery setting, the reasonable quality in treatment is compromised especially in inguinal hernia surgery.

Factors of selection and failure of ambulatory incisional hernia repair: A cohort study of 1429 patients

BACKGROUND

Ambulatory surgery for incisional hernia repair (IHR) is not a widespread practice and is mainly performed for small incisional hernias.

AIM

To assess outpatient IHR practice in France and to identify predictive factors of selection and failure of ambulatory procedures.

METHOD

Surgeons of the French "Club Hernie" prospectively gathered data concerning IHR over a period of almost 5years within a nationwide database.

RESULTS

A number of patients (1429) were operated on during the period of the study. The mean age was 63.3 (22-97) years old. An ambulatory procedure was planned in 305 (21%) patients. Among these, 272 (89%) IHR were effectively performed as one-day procedures. Upon multivariate analysis, predictive factors influencing practitioners for not propose an ambulatory care were increasing age (OR 0.97, P<0.001), body mass index (OR 0.95, P<0.001), ASA grade≥III (OR 0.23, P<0.001), hernia width≥4cm (OR 0.44, P<0.001), recurrent hernia (OR 0.55, P=0.01) and a laparoscopic IHR (OR 0.54, P<0.001). A number of patients (1157) were not selected preoperatively for outpatient IHR mainly because of organizational issues or an ASA grade≥III. Medical or social reasons were the main causes of failure of initially planned ambulatory settings.

CONCLUSION

Ambulatory IHR is a safe and feasible practice subject to a good preoperative selection of the patients. Increasing age, body mass index, ASA grade≥III, hernia width≥4cm, recurrent hernia and a laparoscopic IHR were identified to be preoperative factors for not proposing an ambulatory care. One-day surgery for IHR could be systematically proposed for IHR of small incisional hernias (<4cm) in young patients with few comorbidities.

Inguinal hernia repair in day surgery: the role of MAC (Monitored Anesthesia Care) with remifentanil

BACKGROUND

The extension of indications for procedures in a Day Surgery (DS) setting has led to changes in the anesthetic and surgical treatment of Inguinal Hernias (IH). According to the recommendations of the European Hernia Society, the treatment of IH in DS units should be performed under Monitored Anesthesia Care (MAC).

PATIENTS AND METHODS

960 patients underwent IH repairs over a period of 24 months. The patients were randomly divided into two groups: R (remifentanil) and F (fentanyl); the group F was considered as a control group. The exclusion criteria in both group were: morbid obesity (BMI>40 or BMI>35 in association with high blood pressure or diabetes); coagulopathy; OSAS (obstructive sleep apnea syndrome) with AHI >10; cardiovascular, respiratory, renal, hepatic or metabolic disease; history of substances abuse; GERD-related esophagitis (gastro-esophageal reflux disease); chronic analgesic use; allergy to local anesthetic and ASA>III. Patients reported their level of pain on a verbal numeric scale (VNS), with scores ranging from 0 to 10. For each patient systolic and diastolic blood pressure (SBP and DBP), mean arterial pressure (MAP), heart rate (HR) and peripheral oxygen saturation (SpO2) were recorded. The results are presented as the mean value ± standard deviations; statistical analysis was performed using Student's t-test.

RESULTS

Amongst the 960 procedures, complications or side effects related to the anesthetic techniques didn't occur; no procedure-related complications requiring mechanical ventilation support were reported. Our research focused on evaluating remifentanil effectiveness in pain control and its impact on hemodynamic stability and respiratory function. There was a significant difference between the two groups with regard to the VNS.

CONCLUSIONS

Remifentanil, is an excellent drug for pain control during intra-operative procedures, that allows an optimal hemodynamic stability for IH repairs in a DS setting, due to its pharmacokinetic and pharmacodynamic properties and few adverse effects.

International guidelines for groin hernia management

INTRODUCTION

Worldwide, more than 20 million patients undergo groin hernia repair annually. The many different approaches, treatment indications and a significant array of techniques for groin hernia repair warrant guidelines to standardize care, minimize complications, and improve results. The main goal of these guidelines is to improve patient outcomes, specifically to decrease recurrence rates and reduce chronic pain, the most frequent problems following groin hernia repair. They have been endorsed by all five continental hernia societies, the International Endo Hernia Society and the European Association for Endoscopic Surgery.

METHODS

An expert group of international surgeons (the HerniaSurge Group) and one anesthesiologist pain expert was formed. The group consisted of members from all continents with specific experience in hernia-related research. Care was taken to include surgeons who perform different types of repair and had preferably performed research on groin hernia surgery. During the Group's first meeting, evidence-based medicine (EBM) training occurred and 166 key questions (KQ) were formulated. EBM rules were followed in complete literature searches (including a complete search by The Dutch Cochrane database) to January 1, 2015 and to July 1, 2015 for level 1 publications. The articles were scored by teams of two or three according to Oxford, SIGN and Grade methodologies. During five 2-day meetings, results were discussed with the working group members leading to 136 statements and 88 recommendations. Recommendations were graded as "strong" (recommendations) or "weak" (suggestions) and by consensus in some cases upgraded. In the Results and summary section below, the term "should" refers to a recommendation. The AGREE II instrument was used to validate the guidelines. An external review was performed by three international experts. They recommended the guidelines with high scores. The risk factors for inguinal hernia (IH) include: family history, previous contra-lateral hernia, male gender, age, abnormal collagen metabolism, prostatectomy, and low body mass index. Peri-operative risk factors for recurrence include poor surgical techniques, low surgical volumes, surgical inexperience and local anesthesia. These should be considered when treating IH patients. IH diagnosis can be confirmed by physical examination alone in the vast majority of patients with appropriate signs and symptoms. Rarely, ultrasound is necessary. Less commonly still, a dynamic MRI or CT scan or herniography may be needed. The EHS classification system is suggested to stratify IH patients for tailored treatment, research and audit. Symptomatic groin hernias should be treated surgically. Asymptomatic or minimally symptomatic male IH patients may be managed with "watchful waiting" since their risk of hernia-related emergencies is low. The majority of these individuals will eventually require surgery; therefore, surgical risks and the watchful waiting strategy should be discussed with patients. Surgical treatment should be tailored to the surgeon's expertise, patient- and hernia-related characteristics and local/national resources. Furthermore, patient health-related, life style and social factors should all influence the shared decision-making process leading up to hernia management. Mesh repair is recommended as first choice, either by an open procedure or a laparo-endoscopic repair technique. One standard repair technique for all groin hernias does not exist. It is recommended that surgeons/surgical services provide both anterior and posterior approach options. Lichtenstein and laparo-endoscopic repair are best evaluated. Many other techniques need further evaluation. Provided that resources and expertise are available, laparo-endoscopic techniques have faster recovery times, lower chronic pain risk and are cost effective. There is discussion concerning laparo-endoscopic management of potential bilateral hernias (occult hernia issue). After patient consent, during TAPP, the contra-lateral side should be inspected. This is not suggested during unilateral TEP repair. After appropriate discussions with patients concerning results tissue repair (first choice is the Shouldice technique) can be offered. Day surgery is recommended for the majority of groin hernia repair provided aftercare is organized. Surgeons should be aware of the intrinsic characteristics of the meshes they use. Use of so-called low-weight mesh may have slight short-term benefits like reduced postoperative pain and shorter convalescence, but are not associated with better longer-term outcomes like recurrence and chronic pain. Mesh selection on weight alone is not recommended. The incidence of erosion seems higher with plug versus flat mesh. It is suggested not to use plug repair techniques. The use of other implants to replace the standard flat mesh in the Lichtenstein technique is currently not recommended. In almost all cases, mesh fixation in TEP is unnecessary. In both TEP and TAPP it is recommended to fix mesh in M3 hernias (large medial) to reduce recurrence risk. Antibiotic prophylaxis in average-risk patients in low-risk environments is not recommended in open surgery. In laparo-endoscopic repair it is never recommended. Local anesthesia in open repair has many advantages, and its use is recommended provided the surgeon is experienced in this technique. General anesthesia is suggested over regional in patients aged 65 and older as it might be associated with fewer complications like myocardial infarction, pneumonia and thromboembolism. Perioperative field blocks and/or subfascial/subcutaneous infiltrations are recommended in all cases of open repair. Patients are recommended to resume normal activities without restrictions as soon as they feel comfortable. Provided expertise is available, it is suggested that women with groin hernias undergo laparo-endoscopic repair in order to decrease the risk of chronic pain and avoid missing a femoral hernia. Watchful waiting is suggested in pregnant women as groin swelling most often consists of self-limited round ligament varicosities. Timely mesh repair by a laparo-endoscopic approach is suggested for femoral hernias provided expertise is available. All complications of groin hernia management are discussed in an extensive chapter on the topic. Overall, the incidence of clinically significant chronic pain is in the 10-12% range, decreasing over time. Debilitating chronic pain affecting normal daily activities or work ranges from 0.5 to 6%. Chronic postoperative inguinal pain (CPIP) is defined as bothersome moderate pain impacting daily activities lasting at least 3 months postoperatively and decreasing over time. CPIP risk factors include: young age, female gender, high preoperative pain, early high postoperative pain, recurrent hernia and open repair. For CPIP the focus should be on nerve recognition in open surgery and, in selected cases, prophylactic pragmatic nerve resection (planned resection is not suggested). It is suggested that CPIP management be performed by multi-disciplinary teams. It is also suggested that CPIP be managed by a combination of pharmacological and interventional measures and, if this is unsuccessful, followed by, in selected cases (triple) neurectomy and (in selected cases) mesh removal. For recurrent hernia after anterior repair, posterior repair is recommended. If recurrence occurs after a posterior repair, an anterior repair is recommended. After a failed anterior and posterior approach, management by a specialist hernia surgeon is recommended. Risk factors for hernia incarceration/strangulation include: female gender, femoral hernia and a history of hospitalization related to groin hernia. It is suggested that treatment of emergencies be tailored according to patient- and hernia-related factors, local expertise and resources. Learning curves vary between different techniques. Probably about 100 supervised laparo-endoscopic repairs are needed to achieve the same results as open mesh surgery like Lichtenstein. It is suggested that case load per surgeon is more important than center volume. It is recommended that minimum requirements be developed to certify individuals as expert hernia surgeon. The same is true for the designation "Hernia Center". From a cost-effectiveness perspective, day-case laparoscopic IH repair with minimal use of disposables is recommended. The development and implementation of national groin hernia registries in every country (or region, in the case of small country populations) is suggested. They should include patient follow-up data and account for local healthcare structures. A dissemination and implementation plan of the guidelines will be developed by global (HerniaSurge), regional (international societies) and local (national chapters) initiatives through internet websites, social media and smartphone apps. An overarching plan to improve access to safe IH surgery in low-resource settings (LRSs) is needed. It is suggested that this plan contains simple guidelines and a sustainability strategy, independent of international aid. It is suggested that in LRSs the focus be on performing high-volume Lichtenstein repair under local anesthesia using low-cost mesh. Three chapters discuss future research, guidelines for general practitioners and guidelines for patients.

CONCLUSIONS

The HerniaSurge Group has developed these extensive and inclusive guidelines for the management of adult groin hernia patients. It is hoped that they will lead to better outcomes for groin hernia patients wherever they live. More knowledge, better training, national audit and specialization in groin hernia management will standardize care for these patients, lead to more effective and efficient healthcare and provide direction for future research.

Outpatient groin hernia repair: assessment of 9330 patients from the French "Club Hernie" database

BACKGROUND

Groin hernia repair (GHR) is one of the most frequent surgical interventions practiced worldwide. Outpatient surgery for GHR is known to be safe and effective.

AIM

To assess the outpatient practice for GHR in France and identify predictive factors of failure.

METHOD

Forty one surgeons of the French "Club Hernie" prospectively gathered data concerning successive GHR over a period of 4 years within a multicenter database.

RESULTS

A total of 9330 patients were operated on during the period of the study. Mean age was 61.8 (1-100) years old and 8245 patients (88.4%) were males. 6974 GHR (74.7%) were performed as outpatient procedures. In 262 patients (3.6%), the outpatient setting, previously selected, did not succeed. Upon multivariate analysis, predictive factors of ambulatory failure were ASA grade ≥ III (OR 0.42, p < 0.001), bilateral GHR (OR 0.47, p < 0.001), emergency surgery for incarcerated hernia (OR 0.10, p < 0.001), spinal anesthesia (OR 0.27, p < 0.001) and occurrence of an early post-operative complication (OR 0.07, p < 0.001). The more frequent complications were acute urinary retention and surgical site collections. 2094 patients (21.5%) were not selected preoperatively for 1-day surgery.

CONCLUSION

More than 74% of the patients benefited from outpatient surgery for GHR with a poor failure rate. Predictive factors of outpatient GHR failure were ASA grade ≥ III, bilateral GHR, emergency surgery for incarcerated hernia, spinal anesthesia and occurrence of an early post-operative complication. Ambulatory failures were often related to social issues or medical complications. Outpatient surgery criteria could become less restrictive in the future.

IS SAME-DAY INGUINAL HERNIA SURGERY POSSIBLE?

1-INTRODUCTION: The Lichtenstein hernia repair is associated with low recurrence rates and short operation times, and can be performed under local anaesthesia. Thus, this is among the most-preferred methods used in recent years. Our objective was to explore the same-day discharge rates, and the causes of delayed discharge and re-admission to hospital, of patients treated using the Lichtenstein repair method, to evaluate the feasibility of performing same-day hernia surgery in clinical practice. 2.

MATERIALS AND METHODS

. One hundredof a total of 236 patients diagnosed with unilateral inguinal or femoral hernias, who required surgical treatment, and who agreed with the conditions of the study, were prospectively included. All patients were treated using the Lichtenstein mesh repair method, under local anaesthesia between June 2006 and January 2008. We investigated the types and locations of hernias, duration of surgery, seniority of the surgeon, the feasibility of same-day surgery in subgroups stratified by ASA risk scores, and postoperative complication rates, in patients who underwent inguinal surgery under local anaesthesia 3. RESULTS , DISCUSSION AND CONCLUSIONS:. The rates of pain and post-operative complications were very low in hernia patients who underwent same-day surgery under local anaesthesia. The operation reduces the length of hospital stay and helps patients mobilise earlier. Both the literature, and our data, indicate that inguinal hernia repair under local anaesthesia is safe and effective, reducing anaesthesia-related complications and the length of hospital stay; is cost-effective; and is applicable in all patients.

Complications, Pain Control, and Patient Recovery After Local Versus General Anesthesia for Open Inguinal Hernia Repair in Adults—Systematic Review and Meta-analysis

The purpose of this systematic review is to provide an “up-to-date” evidence-based guideline and clarify the possible benefits as well as drawbacks of local anesthesia (LA) and general anesthesia (GA) in open inguinal hernia surgery in adults. Study method comprised randomized controlled trials. Primary outcome measures were complications, pain control, and patient recovery. Secondary outcome measures were patient satisfaction and hernia recurrence. A total of 14 randomized controlled trials contributed to the study. A total of 1677 patients were analyzed, with 953 in the LA group and 724 in the GA group. Complications were statistically less frequent in the LA group compared with the GA group [odds ratio (OR), 0.31; 95% confidence interval (95% CI), 0.15, 0.64). Supplemental intraoperative analgesia had a statistical significance in the LA group, with an OR of 28.93 (95% CI, 7.86, 106.47). Postoperative pain was statistically significantly lower in the LA group [standardized eman difference (SMD), −1.06; 95% CI, −1.64, −0.48)]. Length of stay was shorter for patients who underwent operation under LA compared with those receiving GA (OR, −1.21; 95% CI, −2.08, −0.33]). Time to full mobility was shorter in the LA group, without statistical significance (OR, 3.04; 95% CI, 0.19, 47.90), whereas measuring in SMD showed significance in comparison with GA (SMD, −1.74; 95% CI, −2.34, −1.14). Hernia recurrence was not noted. Patient satisfaction was greater in the LA group (SMD, 0.65; 95% CI, 0.15, 1.15). Compared with GA, LA showed superiority in terms of complications, postoperative pain, length of stay, time to full mobility, and patient satisfaction. Therefore, it appears to be a more appropriate anesthetic technique for open inguinal hernia repair in adults.

Short-term results of open inguinal hernia repair with self-gripping Parietex ProGrip mesh in China: A retrospective study of 90 cases

OBJECTIVES

This study investigated short-term outcomes of Lichtenstein hernia repair using self-gripping Parietex ProGrip mesh in Chinese patients with inguinal hernias.

METHODS

Retrospective analysis of patients undergoing Lichtenstein hernia repair using the Parietex ProGrip mesh at a single hospital in China between July 2012 and June 2013. All patients completed the EuroQol-five dimensions (EuroQoL-5D) and short form-36 questionnaires and were followed up at 1 day, 7 days, 1 month. and 6 months, postoperatively.

RESULTS

Ninety cases (66 males, 24 females) were studied. Mean ± standard deviation (SD) patient age was 48.7 ± 16.8 (range, 21-87) years. Most hernias were Gilbert's type II (23%) or III (31%). During 6 months of follow-up, none of the patients had recurrent hernia or systemic postoperative complications. The mean ± SD pain visual analog scale score decreased from 32 ± 10.6 at postoperative Day 1 to 0.67 ± 2.5 at 6 months. From postoperative Day 1 to 6 months, there were marked improvements in health and health-related quality of life; mean ± SD visual analog scale EuroQoL score increased from 55.3 ± 8 to 95.2 ± 3 and mean ± SD HR EuroQoL score from 0.31 ± 0.07 to 0.95 ± 0.02. At 6 months, mean scores in all eight dimensions of the short form-36 questionnaires had increased from baseline.

CONCLUSION

The use of self-fixating Parietex ProGrip mesh in open inguinal hernia repair is simple, rapid, effective, and safe, and is associated with low postoperative pain and improved quality life among patients.

Quality of life change in elderly patients undergoing open inguinal hernia repair

PURPOSE

A growing proportion of inguinal hernia patients are at least 65 years old. Assessing operational benefits versus risks in this group of elderly patients merits research.

METHODS

Patients in two prospective trials (1:n = 134, 89 elderly; 2:n = 398, 70 elderly) completed RAND-36 questionnaires preoperatively (response rate 100 and 98.5 %, respectively) and at 3 (98.5 %) or 12 months (89.6 %) after open inguinal hernia repair. In both groups, preoperative and postoperative quality of life data were statistically compared within age categories. Quality of life change was compared between age categories. Immediate complications were recorded.

RESULTS

The dimensions physical functioning and pain improved significantly in the elderly and under 65-year-olds. Role functioning/physical and social functioning showed improvement as well, but less constantly. No statistical difference in complication rates was found across age groups.

CONCLUSION

Inguinal hernia surgery improves physical and social dimensions of quality of life among elderly and under 65-year-olds similarly.

Local anesthetic hernia repair in overweight and obese patients

BACKGROUND

Inguinal hernia repair under local anesthesia (LA) has many advantages and is associated with high patient satisfaction. However, there are concerns of exceeding the maximum safe dose of LA agents in overweight and obese patients. The aim of the present study was to establish whether inguinal hernia repair could be safely performed under LA in overweight and obese patients.

METHODS

Patients who underwent elective LA hernia repair under a single consultant surgeon were studied retrospectively. Each patient received the same LA mixture developed at our hospital specifically for hernia repair. The mixture includes lignocaine and bupivocaine, both with adrenaline, made up to a volume of 100 ml with saline. Data were collected by case note review, and by postal and telephone surveys.

RESULTS

A total of 125 patients who underwent LA hernia repair, in whom body mass index (BMI) was measured, were studied. Based on the World Health Organization (WHO) classification, there were 35 (28%) normal weight patients and 63 (72%) overweight (BMI>or=25<30) or obese (BMI>or=30) patients. The median BMI was 27 (range 19-38). The mean volumes of LA mixture used for each group were 58 ml and 62 ml, respectively. High day case rates of 91% and 84% were obtained for the two groups, respectively. Complications included three wound hematomas and three simple wound infections, with no significant differences between groups. One patient developed a recurrent hernia (<1%).

CONCLUSIONS

Local anesthetic inguinal hernia repair in the obese is safe and well tolerated. Use of a large volume local anesthetic mixture is recommended in overweight and obese patients.

Day-case inguinal hernia repair in the elderly: a surgical priority

PURPOSE

To compare patients over 70 years old with those under 50 years old undergoing inguinal hernia repair.

PATIENTS AND METHODS

Fifty patients aged >70 years (group A) and 50 patients age <50 years (group B) underwent local anaesthetic mesh repair. The mean age for group A was 77.2 years (range 70-85) and for group B it was 40.2 years (range 17-49). There were 46 patients with comorbidities in group A and seven in group B. There were 30 patients with cardiac comorbidities in group A and two in group B.

RESULTS

There were no major complications, infections, haematomas or unplanned admissions in either group. Patients >70 years of age had less post-operative discomfort and recovered more quickly than patients aged <50 years. The number of days of analgesic use and time to return to normal activities was longer in the younger group, 6.0 versus 3.4 and 21 versus 13, respectively. There was no significant difference between the groups in patients having discomfort at 3 months post-operatively. More patients were satisfied in the older group, though the difference was not statistically significant.

CONCLUSION

Elective inguinal hernia repair under local anaesthetic in the elderly has a good outcome, even if there are significant comorbidities. Ambulatory surgery is feasible in this age group and age alone or co-existing disease should not be a barrier to elective day-case inguinal hernia repair.

Are there any benefits from minimizing fasting and optimization of nutrition and fluid management for patients undergoing day surgery?

PURPOSE OF REVIEW

As a result of advances in anaesthesia and surgery, an increasing number of surgical procedures are currently possible in the ambulatory setting. Nausea/vomiting and sedation/drowsiness are often associated with delayed discharge and readmission. These symptoms are also related to pharmacological treatment as well as dehydration and fasting. The evidence that preoperative fasting and dehydration not only reduces preoperative well being, but may also affect postoperative recovery is currently being reviewed.

RECENT FINDINGS

In association with minor surgical procedures, rehydration with approximately 1 l fluid, and in cases with a moderate degree of surgery, such as laparoscopic surgery, 1-3 l fluid, given perioperatively will improve postoperative well being and recovery. Administration of a carbohydrate-rich beverage not only provides fluid but also counteracts the negative effects of preoperative fasting, which in turn reduces preoperative hunger and improves well being. Postoperatively, this treatment reduces insulin resistance, which may be relevant in surgery with significant postoperative stress response. Two studies on laparoscopic cholecystectomy demonstrate different results regarding effects on postoperative outcome and nausea/vomiting and further evaluation is required.

SUMMARY

When preoperative dehydration is corrected, postoperative well being and clinical outcome improves. Avoiding preoperative fasting by administration of carbohydrate-rich beverages improves preoperative well being while effects on postoperative recovery in patients undergoing ambulatory surgery need to be further evaluated.

Inguinal hernia repair: local or general anaesthesia?

INTRODUCTION

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.

PATIENTS AND METHODS

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.

RESULTS

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.

CONCLUSIONS

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.

A survey of inguinal hernia repair in Wales with special emphasis on laparoscopic repair

BACKGROUND

The National Institute of Clinical Excellence (NICE) recently published its guidance on the use of laparoscopic repair for inguinal hernias. This study aimed to assess the likely uptake of laparoscopic surgery for inguinal hernias in Wales. In addition the current practice with regards to day case surgery, use of local anaesthesia, antibiotic prophylaxis, thromboembolic prophylaxis and advice regarding convalescence was assessed.

METHODS

A postal questionnaire survey of all consultant surgeons (n = 91) in Wales was performed.

RESULTS

There was a 70% (n = 67) response to the questionnaire. Fifteen percent of surgeons (n = 9) perform laparoscopic inguinal hernia repair in Wales; 10% of surgeons in Wales agreed with the NICE guidance. Lichtenstein hernia repair was the most commonly used the technique to repair primary inguinal hernias in Wales (82%). No surgeon currently is using a laparoscopic repair as the technique of choice for repair of primary inguinal hernias. Eighteen percent of surgeons perform all the procedures as day cases; 15% of surgeons perform more than 90% of the procedures under local anaesthesia; 44% of surgeons do not use any form of thromboprophylaxis for elective inguinal hernia repair, while 78% of the surgeons used routine antibiotic prophylaxis. Post-operative advice regarding return to sedentary work and driving was highly variable (1-4 weeks), as was advice regarding heavy work and sport (2-12 weeks).

CONCLUSIONS

The uptake of laparoscopic surgery for inguinal hernia repair in Wales is low. Only a minority of surgeons agree with the NICE guidance. Similarly the uptake of day case repair and the use of local anaesthesia are minimal. The use of antibiotic and thromboembolic prophylaxis is empirical and inconsistent. There is a need for evidence-based guidelines to standardise the antibiotic prophylaxis, TE prophylaxis and advice regarding post-operative advice.

Outcome of day-case inguinal hernia in elderly patients: how safe is it?

INTRODUCTION

Inguinal hernia repair is well established as a day-case procedure but little is reported about the outcome for elderly patients.

METHODS

A retrospective study was undertaken to compare a study group of patients aged 70 and above with a controlled group of patients aged less than 65 who had day-case inguinal hernia repair (Lichtenstein repair) between January 1996 and December 2004.

RESULTS

A total of 588 patients (282 in the elderly group and 306 in the control group) were studied. Although there were a larger number of higher-risk (ASA III) patients in the elderly group (P < 0.001), unplanned admission, postoperative symptoms, and satisfaction were comparable with those for the younger group.

CONCLUSION

Day-case inguinal hernia repair can be safely offered to patients aged 70 and above.
