Postoperative-treatment following open incisional hernia repair: A survey and a review of literature

Non-operative considerations in relation to groin and ventral hernia repair: local consensus recommendations from the Danish Hernia Database

BACKGROUND

While operative technique is central to hernia repair, non-operative factors such as postoperative activity guidance and the use of abdominal binders significantly influence recovery, quality of life, and long-term outcomes. These considerations are variably addressed in clinical practice and are underrepresented in the literature.

METHODS

This narrative review examines key non-operative aspects of hernia surgery, focusing on groin and ventral hernias. For each type, we discuss postoperative physical activity recommendations, the use and effectiveness of abdominal binders or support binders, and other relevant factors that typically concern the patient during the preoperative visit. As this is a non-systematic review, the recommendations are based on the available literature and consensus discussions within the steering committee of the Danish Hernia Database.

RESULTS

Groin hernia repair typically allows for early mobilization and rarely warrants binder use, although anecdotal evidence supports the use of inguinal binders to prevent seromas in large inguinoscrotal hernias. Some patients may feel subjective comfort wearing such binders for a few weeks after surgery. In ventral hernia repair, individualized guidance and use of support binders may be more effective than in groin hernia repair; decreasing postoperative pain and possibly seroma formation. Despite widespread clinical practices, evidence supporting specific activity restriction recommendations remains limited, and considerable variation exists between surgeons and institutions. After consensus discussions, we recommend the immediate resumption of normal daily activities, whereas sports and heavy lifting should wait 2-4 weeks after the operation.

CONCLUSION

Non-operative considerations are important for the patient and often serve as central discussion points during the preoperative visit. A stronger evidence base, improved standardization, and broader implementation of patient-centered tools could enhance recovery, reduce complications, and better align surgical success with patient well-being and satisfaction.

Retromuscular, periprosthetic drainage after hernioplasty with sublay mesh reinforcement in ventral hernias results in less retromuscular fluid collections but longer hospital stay and analgetic use with unclear effect on clinical outcome - a randomized controlled trial

PURPOSE

To determine whether periprosthetic drain insertion for hernioplasty using sublay mesh augmentation influences retromuscular fluid collections (RFC) and the clinical course.

METHODS

Forty-two patients with open repair of midline hernias (M2-4, W1, European Hernia Society classification) were allocated to groups with or without retromuscular drains. Subcutaneous drainages were used in both groups to avoid confounding from surgical site occurrences due to superficial, subcutaneous fluid collections. The participants underwent clinical and ultrasound assessments on postoperative days (POD) 14 and 30 to detect RFC, subcutaneous seromas, and wound complications. The sample size was estimated using the RFC of a test cohort with drainage; the assumed relevant volume (5 ml) was calculated comprising 84% (mean + 1 SD) of these patients.

RESULTS

In the retromuscular drainage group, the RFC median volume was reduced by 75.2% on POD 14, and by POD 30, no RFC were found [0.2 vs. 25.8 (p < 0.001) and 0 vs. 4.0 (p = 0.02) on PODs 14 and 30, respectively]. The number of patients with RFC ≥ 5 mL was also significantly lower in the drainage group [4 vs. 12 (p = 0.02) and 1 vs. 8 (p = 0.02) on PODs 14 and 30, respectively]. No surgical site infections occurred in either group, but retromuscular hematoseroma led to one revision surgery and one needle aspiration in the group without drainage. In the drainage group, a significantly longer hospital stay (6.5 days vs. 4 days; p = 0.01) and longer regular analgetic intake (6 vs. 3 days; p = 0.03) were observed. Multivariable regression revealed that retromuscular drainage usage was the only independent predictor of the RFC volume.

CONCLUSION

We found that the use of retromuscular drains after hernioplasty with sublay hernia repair reduced periprosthetic fluid collections in our population but prolonged hospital stay. Whether the reduction of RFC can prevent SSO or revision surgery cannot be determined from our data, the relevance is therefore not assessable. Hence, further larger studies are required to determine the clinical relevance of drains.

Is There a Clinical Benefit of Abdominal Binders After Abdominal Surgery: A Systematic Literature Review

Background

The incidence of incisional hernia following laparotomy varies between 2% and 30%. It is well-established that the need to control several risk factors prior to surgery exists (weight loss before surgery, diabetes control). Postoperative abdominal binder (AB) is often recommended by surgeons, yet evidence on this topic is lacking. The aim of this review was to present current evidence on the use of abdominal binders after abdominal surgery.

Material and Methods

A comprehensive literature review between January and May 2024 was conducted using a range of search engines, including PubMed, Science Direct, EMBASE, Google Scholar, and Google. The following keywords were used: "abdominal binder," "abdominal support," "hernia," "girdle and hernia," "compression belt and hernia," and "abdominal support and hernia."

Results

Sixteen articles were selected for further analysis (7 RCTs, 6 non-RCTs and 3 meta-analyses). None of the studies reported a reduction in the incidence of abdominal dehiscence or incisional hernia. Postoperative use of the AB has been shown to reduce postoperative discomfort and pain for a limited period of up to 48-72 h. There was no discernible difference in the incidence of surgical site complications.

Conclusion

The current evidence indicates that the use of AB following abdominal surgery is safe, although no benefit has been established (except 48 h after surgery). AB may enhance comfort in select patients; however, further studies are necessary to justify their routine use, with a particular focus on the medical and economic implications.

Outcomes of elective and emergency surgical repair of incisional hernia: a comparative observational study

PURPOSE

Incisional hernia (IH) is a common complication following abdominal surgery. Surgical repair of IH is associated with the alleviation of symptoms and improvement of quality of life. Operative intervention can pose a significant burden to the patient and healthcare facilities. This study aims to describe and compare outcomes of elective and emergency surgical repair of IH.

METHODS

This study is a single-centre comparative retrospective study including patients who had repair of IH. Patients were divided into Group I (Emergency) and Group II (Elective), and a comparison was conducted between them.

RESULTS

Two hundred sixty-two patients were identified with a mean age of 61.8 ± 14.2 years, of which 152 (58%) were females. The mean BMI was 31.6 ± 7.2 kg/m2. More than 58% had at least one comorbidity. 169 (64.5%) patients had an elective repair, and 93 (35.5%) had an emergency repair. Patients undergoing emergency repair were significantly older and had higher BMI, p = 0.031 and p = 0.002, respectively. The significant complication rate (Clavien-Dindo III and IV) was 9.54%. 30 and 90-day mortality rates were 2.3% (n = 6) and 2.68% (n = 7), respectively. In the emergency group, the overall complications, 30-day and 90-day mortality rates were significantly higher than in the elective group, p ≤ 0.001, 0.002 and 0.001, respectively. Overall, 42 (16.1%) developed wound complications, 25 (9.6%) experienced a recurrence, and 41 (15.71%) were readmitted within 90 days, without significant differences between the two groups.

CONCLUSION

Patients who underwent emergency repair were significantly older and had a higher BMI than the elective cases. Emergency IH repair is associated with higher complication rates and mortality than elective repair.

[Physical Strain after Abdominal Surgery - Results of a Patient Survey]

INTRODUCTION

Incision hernias are common complications after abdominal surgery and affect the recommendations on postoperative physical strain, as it is thought that excessively early strain causes incisional hernias. However, there is no evidence to justify this. This study evaluates the effect of postoperative strain on the risk of incisional hernia.

MATERIALS AND METHODS

Patients with a laparoscopy (LS) or laparotomy (LT) were asked to complete a questionnaire on postoperative strain, complaints and quality of life. Patients with hernia surgery, or open abdomen therapy for complicated courses (Clavien-Dindo > III) were excluded.

RESULTS

393 patients completed the questionnaire (43.6%). 274 were LS and 128 LT. The incidence of incisional hernias was 5.2% (LS) and 18.0% (LT, p = 0.001). Incisional hernia patients were younger and more commonly males. 30.5% of incisional hernia patients did not return to normal physical strain postoperatively. Abdominal binders did not affect the hernia rate. The incisional hernia patients showed decreased quality of life scores in both mental and physical domains.

CONCLUSION

Early postoperative physical strain was not a risk factor for incisional hernia development in this study. However, prospective studies are needed to create necessary evidence to recommend earlier postoperative return to normal physical strain.

Incisional Hernia: A Surgical Complication or Medical Disease?

Incisional hernia (IH) is a frequent complication following abdominal surgery. The development of IH could be more sophisticated than a simple anatomical failure of the abdominal wall. Reported IH incidence varies among studies. This review presented an overview of definitions, molecular basis, risk factors, incidence, clinical presentation, surgical techniques, postoperative care, cost, risk prediction tools, and proposed preventative measures. A literature search of PubMed was conducted to include high-quality studies on IH. The incidence of IH depends on the primary surgical pathology, incision site and extent, associated medical comorbidities, and risk factors. The review highlighted inherent and modifiable risk factors. The disorganisation of the extracellular matrix, defective fibroblast functions, and ratio variations of different collagen types are implicated in molecular mechanisms. Elective repair of IH alleviates symptoms, prevents complications, and improves the quality of life (QOL). Recent studies introduced risk prediction tools to implement preventative measures, including suture line reinforcement or prophylactic mesh application in high-risk groups. Elective repair improves QOL and prevents sinister outcomes associated with emergency IH repair. The watchful wait strategy should be reviewed, and options should be discussed thoroughly during patients' counselling. Risk stratification tools for predicting IH would help adopt prophylactic measures.

The effect of an abdominal binder on postoperative outcome after open incisional hernia repair in sublay technique: a multicenter, randomized pilot trial (ABIHR-II)

INTRODUCTION

Although the evidence is minimal, an abdominal binder is commonly prescribed after open incisional hernia repair (IHR) to reduce pain. This study aimed to investigate this common postoperative treatment.

METHODS

The ABIHR-II trial was a national prospective, randomized, multicenter non-AMG/MPG pilot study with two groups of patients (wearing an abdominal binder (AB) for 2 weeks during daytime vs. not wearing an AB following open IHR with the sublay technique). Patient enrollment took place from July 2020 to February 2022. The primary endpoint was pain at rest on the 14th postoperative day (POD) using the visual analog scale (VAS). The use of analgesics was not systematically recorded. Mixed-effects linear regression models were used.

RESULTS

A total of 51 individuals were recruited (25 women, 26 men; mean age 61.4 years; mean body mass index 30.65 kg/m2). The per-protocol analysis included 40 cases (AB group, n = 21; No-AB group, n = 19). Neither group showed a significant difference in terms of pain at rest, limited mobility, general well-being, and seroma formation and rate. Patients among the AB group had a significantly lower rate of surgical site infection (SSI) on the 14th POD (AB group 4.8% (n = 1) vs. No-AB group 27.8% (n = 5), p = 0.004).

CONCLUSION

Wearing an AB did not have an impact on pain and seroma formation rate but it may reduce the rate of postoperative SSI within the first 14 days after surgery. Further trials are mandatory to confirm these findings.

Do surgical drains reduce surgical site occurrence and infection after incisional hernia repair with sublay mesh? A non-randomised pilot study

INTRODUCTION

Surgical site occurrence (SSO) and surgical site infection (SSI) are common concerns with incisional hernia repair. Intraoperative drain placement is a common practice aiming to reduce SSO and SSI rates. However, literature on the matter is very poor. The aim of this study is to investigate the role of subcutaneous and periprosthetic drain placement on postoperative outcomes and SSO and SSI rates with incisional hernia repair.

METHODS

A non-randomised pilot study was performed between January 2018 and December 2020 and included patients with elective midline or lateral incisional hernia repair with sublay mesh placement. Patients were prospectively included, followed for 1 month and divided into three groups: group 1 without drainage, group 2 with subcutaneous drainage, and group 3 with subcutaneous and periprosthetic drains. Drains were placed at surgeon's discretion. All patients were included in the enhanced recovery program.

RESULTS

One hundred and four patients were included. Twenty-four patients (23.1%) did not have drains (group 1), 60 patients (57.7%) had a subcutaneous drain (group 2) and 20 patients (19.2%) had both a subcutaneous and a periprosthetic drains (group 3). SSO rates were significantly different between the 3 groups: 20.8% in group 1, 20.7% in group 2 and 50% in group 3 (p = 0.03). There was no significant difference in deep and superficial SSI rates between the 3 groups. Subgroup analysis revealed that adding a drain in direct contact with the mesh significantly increased SSO rate but did not influence SSI rate. Length of stay was also significantly increased by the presence of a drain, 3.1 ± 1.9 days for group 1; 5.9 ± 4.8 for group 2 and 5.9 ± 2.5 days for group 3 (p < 0.005).

CONCLUSION

Drain placement in direct contact with the mesh might increase SSO rate. More studies are necessary to evaluate the actual benefits of drainage after incisional hernia repair.

Full duodenal rupture after direct abdominal trauma in soccer: a case report of an elite soccer player with follow up and return to play protocol

Severe traumatic abdominal injuries and duodenal ruptures are relatively rare in soccer and can be easily missed and turn into a life-threatening condition. All team physicians need to be familiar with the warning sign in these situations. This report aims to report a case, discuss the diagnostic and treatment process and the return to play protocol.During a professional female soccer team training session, the injury occurred while the player's epigastrium was hit hardly by the opponent's knee. In the first evaluation, there was only mild epigastrium pain without any other sign. Eventually, pain exacerbated, nausea and vomiting were added. All the initial evaluation (Physical examination, abdominal X-ray, ultrasonography, blood tests) were normal. Eventually, she developed abdominal guarding and underwent abdominopelvic computed tomography with intravenous contrast where Duodenal rupture becomes evident. She underwent laparotomy and full duodenal repair and discharged from the hospital in good health.For the return to play determination in such injuries, the abdomen should not be imposed on any trauma for about 6 months, so while the player can start a self-training session firstly without a ball and then with a ball, she is not allowed to play or train with others for 6 months.

Biomechanical Influences on Mesh-Related Complications in Incisional Hernia Repair

Aim: Hernia repair strengthens the abdominal wall with a textile mesh. Recurrence and pain indicate weak bonds between mesh and tissue. It remains a question which biomechanical factors strengthen the mesh-tissue interface, and whether surgeons can enhance the bond between mesh and tissue. Material and Methods: This study assessed the strength of the mesh-tissue interface by dynamic loads. A self-built bench test delivered dynamic impacts. The test simulated coughing. Porcine and bovine tissue were used for the bench test. Tissue quality, mesh adhesiveness, and fixation intensity influenced the retention power. The influences were condensed in a formula to assess the durability of the repair. The formula was applied to clinical work. The relative strength of reconstruction was related to the individual human abdominal wall. From computerized tomography at rest and during Valsalva's Maneuver, the tissue quality of the individual patient was determined before surgery. Results: The results showed that biomechanical parameters observed in porcine, bovine, and human tissue were in the same range. Tissues failed in distinct patterns. Sutures slackened or burst at vulnerable points. Both the load duration and the peak load increased destruction. Stress concentrations elevated failure rates. Regional areas of force contortions increased stress concentrations. Hernia repair improved strain levels. Measures for improvement included the closure of the defect, use of higher dynamic intermittent strain (DIS) class meshes, increased mesh overlap, and additional fixation. Surgeons chose the safety margin of the reconstruction as desired. Conclusion: The tissue quality has now been introduced into the concept of a critical and a gained resistance toward pressure-related impacts. A durable hernia repair could be designed from available coefficients. Using biomechanical principles, surgeons could minimize pain levels. Mesh-related complications such as hernia recurrence can potentially be avoided in incisional hernia repair.

Recommendations on Postoperative Activities After Abdominal Operations and Incisional Hernia Repair-A National and International Survey

Background: There is no conclusive data on postoperative recommendations after abdominal and hernia surgery, and there is significant variation in the literature on that question. Thus, this study evaluates the status quo of recommendations of postoperative activity restriction after abdominal surgery. Materials and Methods: A national (German) and international survey of general surgeons on postoperative recommendations after abdominal and hernia surgery was pooled and analyzed. Results: A total of 74.6% recommended postoperative reduced activity for 2 weeks or less after laparoscopy. For midline laparotomy, 48.8% considered a reduced activity of 4 weeks or less to be sufficient. A majority from the national survey recommended more than 4 weeks instead (60.2%), whereas only 31.5% from the international survey did so (p = 0.000). In the pooled analysis, 258 of 450 (57.3%) rated 4 weeks or less suitable. However, the recommendations differed significantly between the surveys (4 weeks or less: a national survey, 47.1% vs. international survey, 64.6%; p = 0.000). Conclusion: There was substantial variation in the given recommendations. However, we found no evidence against immediate mobilization, reduced physical activity, and lifting for up to 2 weeks after laparoscopic surgery and for up to 4 weeks after open abdominal surgery and open incisional/ventral hernia repair in uncomplicated and standard cases. There might be individual and socioeconomic benefits to allow patients to return to their whole personal level of activity and work without putting them at risk of complications. Due to lack of evidence, both retrospective and prospective, controlled studies are in need to develop reliable recommendations.

The Effect of an Abdominal Binder on Postoperative Pain after Laparoscopic Incisional Hernia Repair-A Multicenter, Randomized Pilot Trial (ABIHR-I) of the Intraperitoneal Onlay-Mesh Technique

BACKGROUND

Incisional hernias with apertures measuring less than 7 cm can generally be treated adequately with the laparoscopic intraperitoneal onlay-mesh (IPOM) technique. The wearing of an abdominal binder after surgery is often recommended in order to promote wound healing and prevent recurrent herniation. We carried out a multicenter, randomized pilot trial to evaluate the utility of abdominal binders.

METHODS

The trial was conducted from May 2019 to December 2020. Persons treated for an incisional hernia with a laparoscopic IPOM procedure were included in the trial and randomized preoperatively into two equal-sized groups: the patients in one group wore an abdominal binder during the daytime for 14 days after surgery, while those in the other group wore no binder. The primary endpoint was pain at rest on postoperative days 1, 2, and 14, as measured on a visual analog scale. The secondary endpoints were overall subjective wellbeing, the rates of wound infection and recurrence, the complication rate, mobility, and the rate and size of postoperative wound seroma formation (on postoperative days 1, 2, and 14).

RESULTS

40 patients were included in the pilot trial. Three had to be excluded because of intraoperative conversion to an open surgical technique. The binder and no-binder groups (18 and 19 patients, respectively) did not differ in their biometric and perioperative data to any statistically significant extent. The patients in the binder group had significantly less postoperative pain (F [dfn, dfd] 4.44, 95% confidence interval [1; 35], p = 0.042).The patients in the binder group also had better overall subjective well-being and a higher rate of postoperative wound seroma formation than those in the no-binder group, but these differences did not reach statistical significance. The patients in the binder group had less limitation of mobility than those in the other group; this difference did not reach statistical significance, either.

CONCLUSION

A postoperatively worn abdominal binder may reduce pain after incisional hernia repair with the IPOM technique. The postoperative use of analgesic medication was not measured.

Postoperative Work and Activity Restrictions After Abdominal Surgery: A Systematic Review

OBJECTIVE

This systematic review aims to assess what is known about convalescence following abdominal surgery. Through a review of the basic science and clinical literature, we explored the effect of physical activity on the healing fascia and the optimal timing for postoperative activity.

BACKGROUND

Abdominal surgery confers a 30% risk of incisional hernia development. To mitigate this, surgeons often impose postoperative activity restrictions. However, it is unclear whether this is effective or potentially harmful in preventing hernias.

METHODS

We conducted 2 separate systematic reviews using Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The first assessed available basic science literature on fascial healing. The second assessed available clinical literature on activity after abdominal surgery.

RESULTS

Seven articles met inclusion criteria for the basic science review and 22 for the clinical studies review. The basic science data demonstrated variability in maximal tensile strength and time for fascial healing, in part due to differences in layer of abdominal wall measured. Some animal studies indicated a positive effect of physical activity on the healing wound. Most clinical studies were qualitative, with only 3 randomized controlled trials on this topic. Variability was reported on clinician recommendations, time to return to activity, and factors that influence return to activity. Interventions designed to shorten convalescence demonstrated improvements only in patient-reported symptoms. None reported an association between activity and complications, such as incisional hernia.

CONCLUSIONS

This systematic review identified gaps in our understanding of what is best for patients recovering from abdominal surgery. Randomized controlled trials are crucial in safely optimizing the recovery period.

Lack of Standardized Advice on Physical Strain Following Abdominal Surgery

BACKGROUND

In Germany as elsewhere, standardized recommendations are lacking on the avoidance of physical exertion to protect the abdom - inal wall in patients who have recently undergone abdominal surgery. It is unclear how much stress the abdominal wall can withstand and how long the patient should be exempted from work. The goal of this review is to determine whether there are any standardized, evidence-based recommendations for postoperative care from which valid recommendations for Germany can be derived.

METHODS

We systematically searched the literature for evidence-based recommendations on exertion avoidance after abdominal surgery, as well as for information on the extent to which postoperative abdominal wall stress contributes to incisional hernia formation. We then created a questionnaire on recommendation practices and sent it to all of the chiefs of general and visceral surgery services that were listed in the German hospital registry (1078 chiefs of service as of June 2016).

RESULTS

All 16 of the included studies on postoperative exertion avoidance contained low-level evidence that could only be used to formulate weak recommendations ("can," rather than "should" or "must"). Some 50 000 incisional hernia repair procedures are performed in Germany each year, with a reported incidence of 12.8% in the first two years after surgery. The scientifically documented risk factors for incisional herniation are related to techniques of wound closure, the suture materials used, wound infections, and the patient risk profile. From the biological point of view, the abdominal wall regains full, normal resistance to exertional stress 30 days after a laparotomy with uncomplicated healing. Most incisional hernias (>50%) arise 18 months or more after surgery; they are more common in patients who have avoided exertion for longer periods of time (more than 8 weeks). Our questionnaire was returned by 386 surgical clinics. The responses showed that 78% of recommendations were based on personal experience only. The recommendations varied widely; exertion avoidance was recommended for as long as 6 months.

CONCLUSION

The dilemma of a deficient evidence base for postoperative exertion avoidance to protect the abdominal wall should be resolved with the much higher-quality evidence available from hernia research, which concerns the patient population with the biologically least favorable starting conditions. Based on our analysis of the available literature in light of the biomechanical principles of abdominal wall healing, we propose a new set of recommendations on postoperative exertion avoidance after abdominal surgery, with the goal of eliminating excessively protracted exertion avoidance and enabling a timely return to work.

Comparison of different durations of physical activity restrictions following incisional hernia repair in sublay technique, the 3N6 trial: A prospective clinical trial

BACKGROUND

Incisional hernias (IH) occur in 4 to 20% of cases following abdominal surgeries, often after laparotomies. In the US, there are 4 to 5 million laparotomies performed per year, which could lead to 400.000 to 1.000.000 IHs. Therefore, this disease accounts as an important social-economic factor. Furthermore, these hernias can lead to bowel incarcerations, chronic pain, and a decrease in quality of life. To guarantee sufficient wound healing and decrease the recurrence rate, physical activity restrictions (PAR) are recommended. The standard recommendations for PAR seem to vary from 0 to 12 weeks, but the evidence remains low due to a lack of clinical trials. Conducting the study at hand, we aim to provide more evidence on this topic.

METHODS

The 3N6 trial will be conducted as a national multicenter prospective trial with two study groups (n = 90), where the goal is to find matched pairs within the two groups. Patients who underwent open incisional hernia repair (IHR) in sublay technique will be enrolled. A patient in the 3-week PAR group will be matched to a patient in the 6-week PAR group based on heavy lifting, male gender, BMI > 30, and large hernia >7 cm. The primary endpoint is the duration of sick leave that patients require to return to work, by comparing PAR of 6 weeks with PAR of 3 weeks. The secondary endpoints are the recurrence rate, seroma formation, and chronic pain one year after surgery and postoperative complications within 30 days using Clavien-Dindo-classification.

DISSEMINATION

The findings will be published in a peer-reviewed journal. We may also present the findings at local and/or national conferences.

Drain tube use in incisional hernia repair: a national survey

PURPOSE

There is debate regarding the use of drain tubes in incisional hernia repair. This has become topical in Australia, with a court judge suggesting that drain tubes are mandatory. There continues to be a lack of evidence to support generalised decision-making regarding the use of drain tubes.

METHODS

The general surgeon membership of General Surgeons Australia (GSA) were surveyed regarding incisional hernia repair, their use of drains, and the decision-making behind their use.

RESULTS

A total of 196 surgeons' survey responses were analysed. Most surgeons perform less than 20 incisional hernia repairs per year (78%), prefer an open approach (78%), and preferably perform a pre-peritoneal (sub-lay) repair (53%). There was a variety of approaches to leaving a drain, with the most common answer being "sometimes" (31.28%) and an equal number of surgeons claiming to always or never leaving a drain (11.79% each). There was also no consensus in the duration the drain should stay in, with most surgeons averaging less than 5 days. Interestingly, there was a range of views on the effects of drain tubes, with some surgeons believing drains decreased infections and more believing they increased infections. Most surgeons felt seromas were decreased, but there was increased post-operative pain. The majority of surgeons agreed there was no evidence to support their beliefs.

CONCLUSION

Placement of drain tubes is not universally practiced by the general surgeons who participated in the survey. The lack of evidence is reflected by a varied approach to incisional hernia repair and the use of drain tubes.

Patient reported outcome following incisional hernia repair: A survey on 163 patients at two maximum care hospitals

Introduction

Incisional hernias of the abdominal wall are frequent complications after laparotomy (9–20%) and often need incisional hernia repair (IHR). In order to ensure wound healing and to therefore prevent postoperative short and long term morbidity carrying an abdominal binder (AB) and physical rest is frequently advised. However, there is a lack of evidence concerning clinical effects regarding these recommendations. Hence, we conducted a survey to analyze the patient reported outcome following IHR.

Methods

From December 2017 to May 2018, we conducted a survey among 270 patients who underwent open and laparoscopic IHR at two maximum care hospitals. They were interviewed about their type of operation, postoperative treatment, recommendations, and outcome.

Results

163 patients replied to the questionnaire. The average age was 63.2 ± 12 years. 74 patients were female and 89 were male. 32.6% of the patients reported an AB-induced immobility and 71.2% reported that the AB reduced pain after IHR. A prolonged period of physical rest and the use of an AB had no statistical significance on postoperative morbidity.

Conclusions

Due to our findings we assume that the AB may induce immobility and reduce postoperative pain. A prolonged period of physical rest and wearing an AB does not seem to have an impact on the postoperative outcome following IHR. Therefore, a shortened duration of physical rest and wearing an AB following IHR should be taken under consideration. To reveal more evidence on this topic further clinical trials are essential.

•

The use of an abdominal binder may reduce pain following incisional hernia repair.

•

On third of the questioned patients reported, that the AB induced immobility.

•

A prolonged period of physical rest and carrying an abdominal binder may not prevent recurrences.
