Outcome of incisional hernia repair in patients 80 years and older: results from the Herniamed-Registry

IntroductionMore and more often complex abdominal surgeries are performed in the elderly. Together with the ageing population these patients are at risk for incisional hernias. We aimed on assessing outcomes following incisional hernia surgery in patients 80 years and older.Material and methodsUsing the Herniamed-Registry, a prospective multi-institutional database, data on patients undergoing surgery for incisional hernias were retrospectively assessed. 46,040 patients were included and divided by age. Intraoperative-, general-, and postoperative complications as well as 1-year follow-up outcomes were assessed and compared between patients 80 years and older vs younger than 80 years.ResultsIntra- (2.3% vs 1.5%; p < 0.001) and postoperative (8.6% vs 7.2%; p = 0.001) complications, general complications (5.5% vs 3.0%; p < 0.001), as well as reoperations (3.8% vs 3.0%; p = 0.007) were more likely to occur in elderly patients. By contrast, recurrences (3.6% vs 4.5%; p = 0.007), pain at rest (7.3% vs 10.1%; p < 0.001) and on exertion (11.3% vs 18.3%; p < 0.001), as well as pain requiring treatment (5.4% vs 7.7%; p < 0.001) was less likely in the group of patients aged ≥ 80 years.ConclusionIncisional hernia repair in patients 80 years and older is associated with a slightly higher complication risk but is quite acceptable and also have improved pain scores. The recurrence difference is also clinically unimportant.

Robotic Versus Open Incisional Ventral Hernia Repair with Sublay Mesh in Overweight Patients: A Case-Control Analysis of Clinical Outcomes and Costs

Abstract Background Robotic incisional hernia repair (RIHR) with sublay mesh is gaining traction as a minimally-invasive alternative to open retro-rectus reconstruction (OIHR). Obesity is a known risk factor for complications following hernia repair. Aims The objective of this study is to compare the clinical outcomes and costs of RIHR versus OIHR with sublay mesh in overweight patients. Methods Patients with a body mass index (BMI) of 25-35 kg/m2 who underwent OIHR or RIHR with sublay mesh over a 2 years’ period were included. Recurrent hernias after mesh repair were excluded. The main outcome was length of hospital stay (LOS). Secondary outcomes included surgical site complications (SSC), visual analog pain score (VAS), analgesic methods, and general complications. Results Ninety patients were included, 45 in each group. The mean length of stay (LOS) was significantly shorter in RIHR (6.8 days ± 4.6 vs. 2.3 days ± 2, p &amp;lt; 0.001), as were VAS at day 0 (3.0 ± 2.7 vs. 1.7 ± 1.8, p = 0.005) and day 1 (4.2 ± 2.2 vs. 2.4 ± 1.8, p &amp;lt; 0.001), with a significant reduction in morphine consumption and epidural analgesia. The mean operative time was 163 min. ± 65 in OIHR and 191 min. ± 94 in RIHR (p = 0.06), despite a higher proportion of component separation in the robotic group (18% vs 33.3%, p = 0.005). The open group had higher rates of SSC (20% vs 2.2%, p = 0.015) and general complications (40% vs 13.3%, p = 0.004). General costs per diagnosis showed a mean reduction of 4797 CHF in the robotic group, mostly due to reduced hospitalization costs (9364 CHF vs. 3472 CHF). Conclusions The robotic approach improved post-operative outcomes of incisional hernia repair with sublay mesh compared to the open approach in overweight patients, without significantly increasing operative time and costs.

O45 OUTCOMES OF INCISIONAL HERNIA REPAIR SURGERY AFTER MULTIPLE RE-RECURRENCES: A PROPENSITY SCORE MATCHED ANALYSIS

Abstract Aim Patients with a re-recurrent hernia may account for up to 20% of all incisional hernia (IH) patients. IH repair in this population may be complex due to an altered anatomical and biological situation as a result of previous procedures and outcomes of IH repair in this population have not been thoroughly assessed. This study aims to assess outcomes of IH repair by dedicated hernia surgeons in patients who have already had two or more re-recurrences. Material and Methods A propensity score matched analysis was performed using a registry-based, prospective cohort. Patients who underwent IH repair after ≥ 2 re-recurrences operated between 2011 and 2018 and who fulfilled 1 year follow-up visit were included. Patients with similar follow-up who underwent primary IH repair were propensity score matched (1:3) and served as control group. Patient baseline characteristics, surgical and functional outcomes were analyzed and compared between both groups. Results Seventy-three patients operated on after ≥ 2 IH re-recurrences were matched to 219 patients undergoing primary IH repair. After propensity score matching, no significant differences in patient baseline characteristics were present between groups. The incidence of re-recurrence was similar between groups (≥ 2 re-recurrences: 25% versus control 24%, p = 0.811). The incidence of complications, as well as long-term pain, was similar between both groups. Conclusions IH repair in patients who have experienced multiple re-recurrences results in outcomes comparable to patients operated for a primary IH with a similar risk profile. Further surgery in patients who have already experienced multiple hernia re-recurrences is justifiable when performed by a dedicated hernia surgeon.

Short-term quality of life comparison of laparoscopic, open, and robotic incisional hernia repairs.

Outcomes of incisional hernia repair (IHR) include recurrence and quality of life (QOL). Operative approaches include laparoscopic, open, and robotic approaches. Data regarding comparative QOL outcomes among these repair types are unknown. Our study evaluates quality of life after three approaches to IHR. Patients undergoing open (OHR), laparoscopic (LIHR), and robotic extra-peritoneal (RIHR) at a single institution from 2009 to 2019 were reviewed from a prospectively managed quality database. Short-term QOL was compared among the three procedures using the Surgical Outcomes Measurement System (SOMS) and Carolinas Comfort Scale (CCS), objective pain scores and postoperative narcotic use. Data regarding length of stay (LOS), emergency department (ED) visits, readmission, reoperations and surgical site infection (SSI) were also collected. A total of 795 patients undergoing IHR were analyzed (418 open, 300 laparoscopic and 77 robotic). Patient were similar in age, gender and co-morbidities. LIHR patients had higher BMI and RIHR patients had larger hernia and mesh size. LOS was longer and rate of SSI was higher for OIHR compared to laparoscopic and RIHR. Patients undergoing LIHR reported increased narcotic use, Visual Analogue Scale (VAS) and CCS pain scores compared to open and robotic repair. Return to daily activity was 4days shorter for robotic than open and laparoscopic repair; ED visits, readmissions, reoperations, and other QOL domains were similar. Our data suggests that short-term quality of life after robotic extra-peritoneal IHR is improved compared to open and laparoscopic repair. Additional follow up is required to determine differences in long-term QOL after IHR.

Hernia Repair Strength Enhanced With Antioxidants

BackgroundIncisional hernia is one of the most common complications of abdominal surgery, and repairs are associated with significant recurrence rates. Mesh repairs are associated with the best outcomes, but failures are not uncommon. Doxycycline has been demonstrated to enhance mesh hernia repair outcomes with associated increases in collagen deposition and improved tensiometric strength. This study compares the outcomes of incisional hernia repair with doxycycline administration and the antioxidant tempol. Materials and methodsTwenty-eight male Sprague Dawley rats underwent a midline hernia creation and an intraabdominal polypropylene mesh repair. The animals were administered saline, doxycycline, tempol, or both, daily for 8 wk. The abdominal wall was harvested at 8 wk and tensiometric strength and biochemical analysis was performed. ResultsThe tensiometric strength of the repair was increased in all experimental groups. Collagen type 1 deposition was increased, and collagen type 3 deposition was decreased in each of the experimental groups relative to control. There was no difference in MMP-2 and MMP-9 levels between control and experimental groups. ConclusionsThe hernia repair strength is equally enhanced with the administration of doxycycline or tempol. Dual therapy provided no benefit over treatment with either single agent. All treatment groups had an increase in collagen type 1:3 ratios, but the mechanism is not well understood. The benefits of antioxidant treatment following hernia repair are similar to treatment with doxycycline. Given the high frequency of incisional hernia repair failures, this study has implications for improving outcomes following ventral hernia repair through the use of either doxycycline or antioxidant therapy.

P185 INCISIONAL HERNIA REPAIR COMPLICATING INFLAMMATORY BOWEL DISEASE

The incidence of incisional hernia (IH) in inflammatory bowel disease (IBD) ranges from 4-20% due to risk factors such as multiple surgeries, immunosuppressives and nutritional issues. However, little is known about the outcome of IH repair in IBD patients. A 56 year old Caucasian female with Crohn’s disease (CD) of the small and large intestine diagnosed 17 years ago presented with abdominal pain and diarrhea. She has secondary loss of response to infliximab, adverse reaction to adalimumab and certolizumab. She had ileocecal resection 10 years ago and small bowel resection with IH repair 6 years ago. She was maintained on vedolizumab (VDZ) every 4 weeks with partial clinical response. Ileo-colonoscopy was normal and MR enterography showed mild enhancement of distal small bowel. Since this did not correlate with her symptoms and biomarker elevation, after a patency capsule confirmed passage, video capsule endoscopy (VCE) was performed showed active inflammation in small bowel. Retained VCE was noted on imaging. Ustekinumab was added for worsening pain and elevated CRP. Due to worsening obstructive symptoms, surgery was performed which showed adherence of intestines to the mesh and capsule was not removed as removal would involve significant small bowel resection and injury to major vasculature. Her capsule eventually passed but later developed intra-abdominal abscess which required surgical debridement. Follow up imaging showed improvement in abscess and she is tolerating regular diet. Higher rates of IH recurrence are seen in CD with post-operative complications like adhesions, wound infections and development of entero-cutaneous fistulas are higher with intra-peritoneal mesh hernia repair compared to pre-peritoneal mesh. This case warrants caution performing IH repair with mesh in IBD patients who may need future surgeries as the mesh poses difficulty to access intra-peritoneal contents with significant post-operative morbidity.

Outcome of incisional hernia repair in patients with Inflammatory Bowel Disease

BackgroundIncisional Hernia (IH) repair in patients with Inflammatory Bowel Disease (IBD) has not been well studied. MethodsOutcomes of 170 patients with IBD who underwent IH repair were included in the study. ResultsThe incidence of recurrence after IH repair in IBD is 27%. Patients with Crohn's disease (CD) had larger defects at the time of repair, higher proportion of bowel resection and a longer postoperative stay when compared to Ulcerative colitis (UC). The only significant predictor of recurrence after IH repair was the number of previous bowel resections prior to hernia repair (HR 1.59, p < 0.01). Three cases (10%) of late onset enterocutaneous fistulas were identified in patients who underwent IH repair with synthetic mesh inlay. ConclusionSurgical repair results in a recurrence of IH in 27% of patients with IBD. The number of previous bowel resections is the only factor that correlates with development of recurrent IH in IBD.

Early outcome of incisional hernia repair using polypropylene mesh: A preliminary report.

Background:The use of prosthetics for open repair of incisional hernia is very recent in our practice. We highlight our experience repairing incisional hernias with polypropylene mesh.Patients and Methods:Patients presenting with incisional hernia >5 cm in length or width received open polypropylene mesh repair and were followed for two years. Data obtained included age, sex, primary surgery causing the hernia, the length of the fascial defect and previous attempts at repair. Post-operative wound complications were recorded. The integrity of the scar and patient satisfaction or concerns with the repair was assessed at each visit.Results:Nineteen females with a mean age of 35 years (range 30-54) underwent repair; most arising from obstetric or gynaecological procedures. Sixteen (82.2%) had midline, 2 (10.5) transverse and 1 (5.3) Pfannenstiel scars. One patient had no previous repair (R0), 7 had undergone one repair (R1), 9 had undergone two repairs (R2) and 1 had three previous repairs (R3). The length of fascial defects ranged from 8 to 18 cm and seroma collection and stitch sinus were the common problems encountered. Two (10.5%) recurrences were recorded in two years.Conclusion:Open mesh repair of incisional hernia carries a low risk of infection and recurrence in two years.

Agreement between patient survey and medical chart: Pitfalls in measurement strategies for hernia recurrence

Little information is available on agreement between patient-reported outcomes and data collected from medical chart abstraction (MCA) for recurring events. Recurring conditions pose a risk of misclassification, especially when events occur relatively close together in time. We examined agreement, predictors of agreement, and relative accuracy of patient survey and MCA for assessment of outcomes of incisional hernia repair (IHR). Surveys to assess hernia outcomes were mailed to 1,124 living patients who underwent ≥ 1 IHR during 1998-2002 at 16 Veteran's Affairs Medical Center study sites. Patients were asked if they developed a recurrence or an infection at their hernia site. Physician-abstracted data from the medical chart were compared with patient response. Chi-square tests were used to assess significance. Of 487 (43.3%) individuals responding to the survey, 33 (6.8%) with >1 re-repair during 1998-2002 and 98 (20.5%) with a repair before the 1998-2002 period were excluded from the analysis. Although recurrence rates derived from self-reported data and data abstracted from the medical chart were similar (29.3% and 26.1%, respectively), overall concordance was low. Only 49% (n = 54) of self-reported recurrences were confirmed by data abstracted from the medical chart. In addition, 16 (8.3%) recurrences abstracted from the medical chart were not reported by the patient. Factors associated with discordance were high reported pain intensity (P = .02), poorer general health (P = .03), and poorer perceived repair results (P < .0001). Multiple recurrences and subsequent operations across the study period complicate the interpretation of both patient response and data abstracted from the medical chart when referring to a hernia repair. Further study on how best to assess treatment outcomes for recurring conditions is warranted.

Comparable results with 3-year follow-up for large-pore versus small-pore meshes in open incisional hernia repair

Decreasing the amount of polypropylene by increasing pore size produces a lighter weight mesh that may improve tissue ingrowth and, functional properties of the abdominal wall and diminish mesh-related complications. It was the aim of this prospective observational cohort study to analyze the outcome of incisional hernia repair using small-pore versus large-pore meshes and using a standardized, open, retromuscular surgical technique. Across a 6-year period we analyzed 205 patients treated with a heavyweight mesh (group I) and 235 patients treated with a large-pore mesh (group II) for incisional hernias. Patients with a body mass index greater than 40 kg/m(2) and patients with hernias with a transverse diameter of more than 10 cm were not treated by a retromuscular mesh repair and are not included in this analysis. Recurrent incisional hernias also were not included. Both groups had 3 years of follow-up. Patients were evaluated for pain, discomfort, feeling of foreign material, and recurrences. Pre-operative characteristics were comparable between the groups, including body mass index, diabetes, and smoking. The mean total hernia surface was 56 cm(2) for group I versus 48 cm(2) in group II. The mesh surface area was 448 cm(2) for group I and 425 cm(2) for group II. Considering pain scores, there was only a minor difference between the 2 groups at 1-month follow-up, at which time, the Visual Analogue Scale was 5.8 in group I and 4.9 in group II (P = .16). All other scores were comparable between the groups. In group I, 7 recurrences (3.4%) were recorded after 3 years, of which 6 were already apparent 1 year after initial repair. In group II, 9 recurrences (3.8%) were diagnosed, again 6 within the first year after repair. Large-pore meshes can be used safely for open primary incisional hernia repair with an equal outcome compared with small-pore meshes in nonobese patients with defects smaller than 10 cm in width, in regard to both recurrence rates and chronic discomfort.

Intraperitoneal polypropylene mesh repair of incisional hernia is not associated with enterocutaneous fistula.

Incisional hernia repair with prosthetic material is followed by fewer recurrences than primary repair. Polypropylene is the most commonly used prosthetic material but may cause entero- cutaneous fistulas. The aim of this study was to determine whether enterocutaneous fistulas developed after incisional hernia repair with polypropylene mesh and to evaluate clinical outcome after incisional hernia repair. A retrospective analysis of the outcome of incisional hernia repair with polypropylene mesh between 1982 and 1998 was conducted. Follow-up data were obtained from medical records and questionnaires. Polypropylene incisional hernia repair was performed in 136 patients. Median follow-up was 34 months. No enterocutaneous fistulas developed. Wound infection occurred in 6 per cent. Wound sinus formation occurred in two patients. No mesh was removed because of infection and no persisting infection of the mesh occurred. Enterocutaneous fistula formation appears to be very rare after incisional hernia repair with polypropylene mesh, regardless of intraperitoneal placement, omental coverage or closing of the peritoneum.
