Laparoscopic versus open repair of parastomal hernias: an ACS-NSQIP analysis of short-term outcomes

Repair of Parastomal Hernias

Parastomal hernias are an inevitable consequence of ostomy formation and their repairs remain a challenge to many surgeons. With multiple systems of classification and a multitude of techniques for hernia repair ranging from suture to mesh repair, the literature remains sparse with regards to the optimal method of repair. The authors describe the most commonly adopted techniques, discuss preventative measures, and review the current literature in the context of perioperative outcomes and hernia recurrence.

Management of adult intestinal stomas: The 2023 French guidelines

AIM

Digestive stoma are frequently performed. The last French guidelines have been published twenty years ago. Our aim was to update French clinical practice guidelines for the perioperative management of digestive stoma and stoma-related complications.

METHODS

A systematic literature review of French and English articles published between January 2000 and May 2022 was performed. Only digestive stoma for fecal evacuation in adults were considered. Stoma in children, urinary stoma, digestive stoma for enteral nutrition, and rare stoma (Koch, perineal) were not included.

RESULTS

Guidelines include the surgical landmarks to create digestive stoma (ideal location, mucocutaneous anastomosis, utility of support rods, use of prophylactic mesh), the perioperative clinical practice guidelines (patient education, preoperative ostomy site marking, postoperative equipment, prescriptions, and follow-up), the management of early stoma-related complications (difficulties for nursing, high output, stoma necrosis, retraction, abscess and peristomal skin complications), and the management of late stoma-related complications (stoma prolapse, parastomal hernia, stoma stenosis, late stoma retraction). A level of evidence was assigned to each statement.

CONCLUSION

These guidelines will be very useful in clinical practice, and allow to delete some outdated dogma.

Laparoscopic treatment of ventral hernias: the Italian national guidelines

Primary and incisional ventral hernias are significant public health issues for their prevalence, variability of professional practices, and high costs associated with the treatment In 2019, the Board of Directors of the Italian Society for Endoscopic Surgery (SICE) promoted the development of new guidelines on the laparoscopic treatment of ventral hernias, according to the new national regulation. In 2022, the guideline was accepted by the government agency, and it was published, in Italian, on the SNLG website. Here, we report the adopted methodology and the guideline's recommendations, as established in its diffusion policy. This guideline is produced according to the methodology indicated by the SNGL and applying the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) methodology. Fifteen recommendations were produced as a result of 4 PICO questions. The level of recommendation was conditional for 12 of them and conditional to moderate for one. This guideline's strengths include relying on an extensive systematic review of the literature and applying a rigorous GRADE method. It also has several limitations. The literature on the topic is continuously and rapidly evolving; our results are based on findings that need constant re-appraisal. It is focused only on minimally invasive techniques and cannot consider broader issues (e.g., diagnostics, indication for surgery, pre-habilitation).

Contemporary Outcomes of Elective Parastomal Hernia Repair in Older Adults

Importance

Parastomal hernia is a challenging complication following ostomy creation; however, the incidence and long-term outcomes after elective parastomal hernia repair are poorly characterized.

Objective

To describe the incidence and long-term outcomes after elective parastomal hernia repair.

Design, Setting, and Participants

Using 100% Medicare claims, a retrospective cohort study of adult patients who underwent elective parastomal hernia repair between January 1, 2007, and December 31, 2015, was performed. Logistic regression and Cox proportional hazards models were used to evaluate mortality, complications, readmission, and reoperation after surgery. Analysis took place between February and May 2022.

Exposures

Parastomal hernia repair without ostomy resiting, parastomal hernia repair with ostomy resiting, and parastomal hernia repair with ostomy reversal.

Main Outcomes and Measures

Mortality, complications, and readmission within 30 days of surgery and reoperation for recurrence (parastomal or incisional hernia repair) up to 5 years after surgery.

Results

A total of 17 625 patients underwent elective parastomal hernia repair (mean [SD] age, 73.3 [9.1] years; 10 059 female individuals [57.1%]). Overall, 7315 patients (41.5%) underwent parastomal hernia repair without ostomy resiting, 2744 (15.6%) underwent parastomal hernia repair with ostomy resiting, and 7566 (42.9%) underwent parastomal hernia repair with ostomy reversal. In the 30 days after surgery, 676 patients (3.8%) died, 7088 (40.2%) had a complication, and 1740 (9.9%) were readmitted. The overall adjusted 5-year cumulative incidence of reoperation was 21.1% and was highest for patients who underwent parastomal hernia repair with ostomy resiting (25.3% [95% CI, 25.2%-25.4%]) compared with patients who underwent parastomal hernia repair with ostomy reversal (18.8% [95% CI, 18.7%-18.8%]). Among patients whose ostomy was not reversed, the hazard of repeat parastomal hernia repair was the same for patients whose ostomy was resited vs those whose ostomy was not resited (adjusted hazard ratio, 0.93 [95% CI, 0.81-1.06]).

Conclusions and Relevance

In this study, more than 1 in 5 patients underwent another parastomal or incisional hernia repair within 5 years of surgery. Although this was lowest for patients who underwent ostomy reversal at their index operation, ostomy resiting was not superior to local repair. Understanding the long-term outcomes of this common elective operation may help inform decision-making between patients and surgeons regarding appropriate operative approach and timing of surgery.

Parastomal hernia repair: a five-year experience from a single centre in the UK

Parastomal hernias can affect significantly quality of life in patients who often had underwent major operations. The incidence and recurrence is still high although many techniques have been introduced to improve outcomes. Hence, there is still no agreement on what procedure has better results when it comes to repairing a parostomal hernia. Our aim is to compare outcomes of laparoscopic and open parastomal hernia repair in terms of recurrence, reoperations, post-operative complications and length of stay. Sixty-three parastomal hernia repairs were performed in a single Colorectal Centre over a period of 4 years. Eighteen procedures were performed laparoscopically and 45 open. All the 7 emergency procedures were approached open. Both the techniques showed to be safe with post-operative major complication rate (Clavien-Dindo III or above) of 9.52%. The laparoscopic group was found to have a shorter length of stay (p = 0.04) and earlier start of stoma function (p = 0.01), more uneventful recoveries (0.02) and less minor post-operative complications (Clavien-Dindo I or II-p = 0.01,) but similar recurrence rate (p = 0.41). In the open group, the placement of a mesh showed to reduce the rate of recurrence (p = 0.0001). However, this was not found in the laparoscopic approach. In conclusion, the laparoscopic approach showed do give less post-operative complications and a shorter length of stay, with no benefit in the recurrence rate. Considering the open technique, the use of a mesh seemed to reduce the rate of recurrence.

Feasibility of using a tailored mesh in laparoscopic Sugarbaker parastomal hernia repair

BACKGROUND

In parastomal hernia (PH) repair, laparoscopic Sugarbaker technique (LS) is considered the best practice; however, meshes specific for LS repairs ceased to be available.

PURPOSE

The aim of the study was to evaluate feasibility of using a physician-modified mesh (tailored mesh: TM) in LS.

METHODS

Thirty-three patients who underwent LS for PH between June 2012 and September 2021 were examined to compare surgical outcomes between LS with TM (n = 11) and with a ready-made specific mesh (SM, n = 22). All meshes were coated plastic meshes. Statistical analysis was performed with the Mann-Whitney U test and Fisher's exact test. P < .05 was considered to be statistically significant.

RESULTS

We compared the outcomes of TM with SM in LS for similar hernia types during median follow-up periods of 23 (range, 2-29) and 74 (range, 36-110) months (P < .0001), respectively. The median operation times were 146 (range, 45-423) for TM and 193 (range, 65-386) minutes for SM (P = .2301). Perioperative complications were observed in one TM patient (9%) and two SM patients (9%) (P = 1.0000). The lengths of postoperative stay were similar. Recurrence was observed in two cases in the SM group (9%) within 1 year after the operation.

CONCLUSION

In LS, TM seems to be a feasible mesh comparable to SM within short- and mid-term follow-up.

A keyhole approach gives a sound repair for ileal conduit parastomal hernia

PURPOSE

The purpose of this study was to report and evaluate a laparoscopic surgical technique for the treatment of parastomal hernia (PSH) after ileal conduit urinary diversion aiming to minimize PSH recurrence and perioperative complications.

METHODS

We retrospectively evaluated all patients who underwent a PSH (after ileal conduit urinary diversion) repair at Addenbrookes Hospital, Cambridge. As a surgical approach, a laparoscopic repair with mesh was utilized in all cases. Subsequently, we performed a voluntary follow-up of the patients to evaluate long-term recurrence and complication rates. In addition, we conducted a reassessment of the cross-sectional imaging available.

RESULTS

Between November 2008 and December 2019, 27 patients underwent hernia repair due to a clinically significant hernia. Out of those patients, one suffered from a post-operative wound infection. In total 23 patients participated in the follow-up with a median follow-up period of 91 months. Follow-up examination revealed two cases of recurrent PSH (8.7% of patients followed up), four patients suffered from minor complications (14.8%).

CONCLUSION

Repair of PSH associated with ileal conduit is particularly scarce. Our surgical approach presents the only laparoscopic case series of an effective method for treating a PSH from an ileal conduit with a low complication and recurrence rate.

Parastomal Hernia Repair Using a Silo Biologic Mesh

BACKGROUND

A parastomal hernia (PSH) is an enlargement of the stoma's original opening through the abdominal wall's musculature around a colostomy, ileostomy, or urostomy. Its incidence can be up to 48%. The described methods for its repair have high recurrence rate.This article presents a 3-dimensional silo technique for PSH repair (PSH-R). The aims of this technique are to enhance the structural strength of the tunnel wall, to reinforce both the sidewalls and the fascia above and below the muscular opening, and to maintain a stable stoma opening.

METHODS

All consecutive patients undergoing PSH-R with the silo technique between January 2009 and May 2018 by 2 plastic surgeons were included. The outcome parameters of interest were hernia recurrence and wound-related complications.

RESULTS

This study reports 22 patients (9 male, 13 female) with a mean age of 66.7 years and an average body mass index of 29.2. The variety of ostomy types included 10 colostomies, 7 ileostomies, and 5 urostomies. Postoperatively, there were 3 surgical site infections, 1 seroma, and 2 wound healing delays. Six patients were readmitted, 3 of those because of small bowel obstruction. These 3 cases all required reoperation, in addition to 1 operative revision for stoma retraction. During our average follow-up of 19.9 months, 3 cases of PSH recurrence were diagnosed for a recurrence rate of 13.6%.

CONCLUSIONS

This silo technique is associated with favorable complication and low recurrence rates compared with the available techniques in surgical literature. In our practice, it has established itself as a new and safe technique for complex or recurrent PSHs and should be considered in a surgeon's armamentarium. This technique has become our standard for treatment of recurrent PSHs.

Robotic Assisted Repair of Post-Ileal Conduit Parastomal Hernia: Technique and Outcomes

OBJECTIVE

To describe a novel method of robotic assisted laparoscopic parastomal hernia repair (RAL-PHR), including the evolving use of the Da Vinci Single Port (SP) robotic system.

METHODS

Demographic, intraoperative, and postoperative variables were collected for patients who underwent RAL-PHR. The technique for RAL-PHR utilizes a 3 cm incision in the contralateral upper quadrant for the robotic trocar and a 12 mm assistant port. The hernia sac is freed from the fascial defect. Dual Surface Mesh is approximated to the fascial edges with a portion excised to tailor the conduit.

RESULTS

Four patients underwent RAL-PHR and three utilized the SP robot. Median age was 74.4 (range: 69.0-76.9) and median BMI 28.6 (26.5-43.2). All patients underwent cystectomy for bladder cancer and median time from index operation to parastomal hernia repair was 47.3 (40.4-11.48) months. Concurrent operations to hernia repair included ureteroenteric stricture repair, panniculectomy, abdominal wall reconstruction, stoma revision, and incisional hernia repair. Median operative time was 3.9 (2.6-8.7) hours including concurrent operations, median EBL was 50 (10-100) cc, mesh used in 3 cases, with no intraoperative complications reported. Median length of stay was 1 day and 1 post-operative complication greater than Clavien 2 reported. At median follow up of 18.3 (3.63-38.3) months, no recurrences were reported and 1 patient had undergone stoma dilation in the OR.

CONCLUSION

RAL-PHR using the SP system maximizes advantages of laparoscopic repair while allowing for flexibility to perform concurrent procedures and safer takedown of adhesions through just two incisions. RAL-PHR is a safe and effective alternative to open and laparoscopic parastomal hernia repair with several additional benefits.

The Role of Mesh Implants in Surgical Treatment of Parastomal Hernia

A parastomal hernia is a common complication following stoma surgery. Due to the large number of hernial relapses and other complications, such as infections, adhesion to the intestines, or the formation of adhesions, the treatment of hernias is still a surgical challenge. The current standard for the preventive and causal treatment of parastomal hernias is to perform a procedure with the use of a mesh implant. Researchers are currently focusing on the analysis of many relevant options, including the type of mesh (synthetic, composite, or biological), the available surgical techniques (Sugarbaker’s, “keyhole”, or “sandwich”), the surgical approach used (open or laparoscopic), and the implant position (onlay, sublay, or intraperitoneal onlay mesh). Current surface modification methods and combinations of different materials are actively explored areas for the creation of biocompatible mesh implants with different properties on the visceral and parietal peritoneal side. It has been shown that placing the implant in the sublay and intraperitoneal onlay mesh positions and the use of a specially developed implant with a 3D structure are associated with a lower frequency of recurrences. It has been shown that the prophylactic use of a mesh during stoma formation significantly reduces the incidence of parastomal hernias and is becoming a standard method in medical practice.

Emergency laparoscopic treatment of complicated parastomal hernias

Parastomal hernia is not a rare event. Being by definition a complication of ostomy creation, a parastomal hernia also carries the risk of becoming symptomatic and complicated. At present, there are not enough solid data in literature to allow an evidence-based approach to this condition and to its possible complications, especially in the emergency setting. The aim of this paper is to describe through a narrative review of the literature the different surgical approaches concerning parastomal hernias. In order to exemplify the emergency complications we also present two cases in which the watchful waiting approach eventually led to the necessity of urgent surgical treatment, due to bowel incarceration into the parastomal hernia. We chose to tailor the surgical plan on the patient's anatomic and clinical condition, pursuing the laparoscopic approach with two different surgical technique (Sugarbaker and keyhole), each time estimated by the operating surgeon to be the more suitable option for the patient. We acknowledge that laparoscopy can be an optimal choice for the emergency and elective treatment of parastomal hernias, whenever an appropriate know-how is present.

From keyhole to sandwich: change in laparoscopic repair of parastomal hernias at a single centre

BACKGROUND

Nearly 50% of patients with an ostomy will develop a parastomal hernia (PSH). Its repair remains a surgical challenge. Both laparoscopic "modified Sugarbaker" (SB) and Keyhole (KH) repair are currently in use, frequently with unsatisfactory results.''Sandwich Repair'' (SR) may be an alternative to reduce recurrence rates. We present the change of our technique from KH to SR.

METHODS

We collected data from all consecutive laparoscopic PSH repairs at our institution from 2004 until now (from 2004 to 2013 treated with KH, from 2014 with SR) and compared the results of the two groups. Primary endpoint was recurrence rate at 1 year. Secondary outcomes were operative time, PO length of hospital stay (LOS), and short and long-term complications.

RESULTS

13 patients underwent SR. Main changes in surgical technique concerned primary defect closure, no stay sutures, use of glue for first mesh fixation, and partial lateral covering of the underlying mesh with a peritoneal flap. Early postoperative course after SR was uneventful and no recurrence at 1 year was recorded. In the KH group (19 patients), short-term complications occurred in two cases (10%), with one parietal hematoma and one case of intensive pain; we had four recurrences at 1 year (21%). LOS was shorter in the SR group (mean 4 days vs 6, p = 0.004). The KH group had 2 (10%) occurrences of chronic seroma and one bowel perforation (5%), while the SR group had one (8%) occurrence of chronic pain. Median follow-up was 26 months (range 13-78) for the SR group and 47 months (12-105) for the KH group.

CONCLUSION

SR is safe and effective in expert hands and provides promising preliminary results.

Laparoscopic parastomal hernia repair delays recurrence relative to open repair

BACKGROUND

Mesh repair of parastomal hernia is widely accepted as superior to non-mesh repair, yet the most favorable surgical approach is a subject of continued debate. The aim of this study was to compare the clinical outcomes of open versus laparoscopic parastomal hernia repair.

METHODS

An IRB-approved retrospective review was conducted comparing laparoscopic (LPHR) or open (OPHR) parastomal hernia repair performed between 2009 and 2017 at our facilities. Patient demographics, preoperative characteristics, operative details, and clinical outcomes were compared by surgical approach. Subgroup analysis was performed by location of mesh placement. Repair longevity was measured using Kaplan-Meier method and Cox proportional hazards regression. Intention to treat analysis was used for this study based on initial approach to the repair.

RESULTS

Sixty-two patients (average age of 61 years) underwent repair (31 LPHR, 31 OPHR). Patient age, gender, BMI, ASA Class, and comorbidity status were similar between OPHR and LPHR. Stoma relocation was more common in OPHR (32% vs 7%, p = .022). Open sublay subgroup was similar to LPHR in terms of wound class and relocation. Open "Other" and Sublay subgroups resulted in more wound complications compared to LPHR (70% and 48% vs 27%, p = .036). Operative duration and hospital length of stay were less with LPHR (p < .001). After adjustment for prior hernia repair, risk of recurrence was higher for OPHR (p = .022) and Open Sublay and Other subgroups compared to LPHR (p = .005 and p = .027, respectively).

CONCLUSIONS

Laparoscopic repair of parastomal hernias is associated with shorter operative duration, decreased length of stay, fewer short-term wound complications, and increased longevity of repair compared to open repairs. Direct comparison of repair longevity between LPHR and OPHR with mesh using Kaplan-Meier estimate is unique to this study. Further study is warranted to better understand methods of parastomal hernia repair associated with fewer complications and increased durability.

Improved tissue integration of a new elastic intraperitoneal stoma mesh prosthesis

Parastomal herniation is a frequent complication in colorectal surgery, occurring with a prevalence of 30-80%. The aim of the study was to create a new intraperitoneal colostoma mesh prosthesis (IPST) with enhanced elastic properties made with thermoplastic polyurethane (TPU) monofilaments. We performed open terminal sigmoid colostomies reinforced with either a 10 cm by 10 cm polyvinylidene fluoride (PVDF) or a new TPU/PVDF composite mesh in a total of 10 minipigs. Colostoma was placed paramedian in the left lower abdomen and IPST meshes were fixed intraperitoneal. After 8 weeks, the animals were euthanized after laparoscopic exploration and specimen were explanted for histological investigations. Implantation of a new IPST-mesh with enhanced elastic properties was feasible in a minipig model within an observation period of 8 weeks. Immunohistochemically, Collagen I/III ratio as a marker of tissue integration was significantly higher in TPU-group versus PVDF group (9.4 ± 0.5 vs. 8.1 ± 0.5, p = 0.002) with a significantly lower inflammatory reaction measured by a smaller inner granuloma at mesh-colon interface (17.6 ± 3.3 μm vs. 23 ± 5 μm, p < 0.001). A new TPU/PVDF composite mesh with enhanced elastic properties as IPST was created. Stoma surgery and especially the evaluation of the new stoma mesh prosthesis are feasible with reproducible results in an animal model. Tissue integration expressed by Collagen I/III ratio seems to be improved in comparison to standard-elastic PVDF-IPST meshes.

Use of Prophylactic Mesh When Creating a Colostomy Does Not Prevent Parastomal Hernia: A Randomized Controlled Trial-STOMAMESH

OBJECTIVE

The aim of this study was to determine whether parastomal hernia (PSH) rate can be reduced by using synthetic mesh in the sublay position when constructing permanent end colostomy. The secondary aim was to investigate possible side-effects of the mesh.

BACKGROUND

Prevention of PSH is important as it often causes discomfort and leakage from stoma dressing. Different methods of prevention have been tried, including several mesh techniques. The incidence of PSH is high; up to 78%.

METHODS

Randomized controlled double-blinded multicenter trial. Patients undergoing open colorectal surgery, including creation of a permanent end colostomy, were randomized into 2 groups, with and without mesh. A lightweight polypropylene mesh was placed around the colostomy in the sublay position. Follow up after 1 month and 1 year. Computerized tomography and clinical examination were used to detect PSH at the 1-year follow up. Data were analyzed on an intention-to-treat basis.

RESULTS

After 1 year, 211 of 232 patients underwent clinical examination and 198 radiologic assessments. Operation time was 36 minutes longer in the mesh arm. No difference in rate of PSH was revealed in the analyses of clinical (P = 0.866) and radiologic (P = 0.748) data. There was no significant difference in perioperative complications.

CONCLUSIONS

The use of reinforcing mesh does not alter the rate of PSH. No difference in complication rate was seen between the 2 arms. Based on these results, the prophylactic use of mesh to prevent PSH cannot be recommended.

Patients Undergoing Parastomal Hernia Repair Using the Americas Hernia Society Quality Collaborative: A Prospective Cohort Study

BACKGROUND

Parastomal hernia is the most common complication after stoma creation. It can create significant morbidity and is associated with a lower quality of life. Current parastomal hernia repair techniques and outcomes are not well characterized. We aimed to describe patient characteristics, operative techniques, and outcomes of patients undergoing parastomal hernia repair.

STUDY DESIGN

Patients in the Americas Hernia Society Quality Collaborative (AHSQC) ≥18 years old, who underwent parastomal hernia repair were identified. Descriptive statistics were performed for patient demographics, preoperative characteristics, operative details, 30-day follow-up, and patient-reported outcomes. The surgical techniques used in parastomal hernia repair and postoperative outcomes were described, and predictors of open vs minimally invasive surgery (MIS) and type of mesh used were analyzed.

RESULTS

We identified 672 patients in the AHSQC who underwent parastomal hernia repair between 2013 and Nov 2017. Almost all operations were elective, 22% of patents had their stoma reversed, and 94% of repairs used mesh. Elective status and surgeon practice type were associated with use of synthetic mesh. A surgeon's preference for MIS, defect size, and age were associated with use of an MIS approach. Quality of life scores improved for patients who completed a postoperative questionnaire.

CONCLUSIONS

This is the first multi-institutional report of parastomal hernia repair using prospective data complete with operative details. Parastomal hernia repair remains a difficult operation without a clear best practice. Multiple factors appear to influence operative approach. Surgical treatment may improve quality of life at 6 to 12 months postoperatively.

Prosthetic mesh placement for the prevention of parastomal herniation

BACKGROUND

Parastomal herniation is a common problem following formation of a stoma after both elective and emergency abdominal surgery. Symptomatic hernias give rise to a significant amount of patient morbidity, and in some cases mortality, and therefore may necessitate surgical treatment to repair the hernial defect and/or re-site the stoma. In an effort to reduce this complication, recent research has focused on the application of a synthetic or biological mesh, inserted during stoma formation to help strengthen the abdominal wall.

OBJECTIVES

The primary objective was to evaluate whether mesh reinforcement during stoma formation reduces the incidence of parastomal herniation. Secondary objectives included the safety or potential harms or both of mesh placement in terms of stoma-related infections, mesh-related infections, patient-reported symptoms/postoperative quality of life, and re-hospitalisation/ambulatory visits.

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials (CENTRAL; the Cochrane Library 2018, Issue 1), Ovid MEDLINE (1970 to 11 January 2018), Ovid Embase (1974 to 11 January 2018), and Science Citation Index Expanded (1970 to 11 January 2018). To identify ongoing studies, we also searched the metaRegister of Controlled Trials (mRCT) on 11 January 2018.

SELECTION CRITERIA

We considered for inclusion all randomised controlled trials (RCTs) of prosthetic mesh (including biological/composite mesh) placement versus a control group (no mesh) for the prevention of parastomal hernia.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed the studies identified by the literature search for potential eligibility. We obtained the full articles for all studies that potentially met the inclusion criteria and included all those that met the criteria. Any differences in opinion between review authors were resolved by consensus. We pooled study data into a meta-analysis. We assessed heterogeneity by calculation of I2 and expressed results for each variable as a risk ratio (RR) with corresponding 95% confidence intervals (CI). We expressed continous outcomes as mean difference (MD) with corresponding 95% CIs.

MAIN RESULTS

We included 10 RCTs involving a total of 844 participants. The primary outcome was overall incidence of parastomal herniation. Secondary outcomes were rate of reoperation at 12 months, operative time, postoperative length of hospital stay, stoma-related infections, mesh-related infections, quality of life, and rehospitalisation rate. We judged the risk of bias across all domains to be low in six trials. We judged four trials to have an overall high risk of bias.The overall incidence of parastomal hernia was less in participants receiving a prophylactic mesh compared to those who had a standard ostomy formation (RR 0.53, 95% CI 0.43 to 0.66; 10 studies, 771 participants; I2 = 69%; low-quality evidence). In absolute numbers, the incidence of parastomal hernia was 22 per 100 participants (18 to 27) receiving prophylactic mesh compared to 41 per 100 participants having a standard ostomy formation.There were no differences in the need for reoperation (RR 0.90, 95% CI 0.50 to 1.64; 9 studies, 757 participants; I2 = 0%; low-quality evidence); operative time (MD -6.50 (min), 95% CI -18.24 to 5.24; 6 studies, 671 participants; low-quality evidence); postoperative length of hospital stay (MD -0.95 (days), 95% CI -2.03 to 0.70; 4 studies, 500 participants; moderate-quality evidence); or stoma-related infections (RR 0.89, 95% CI 0.32 to 2.50; 6 studies, 472 participants; I2 = 0%; low-quality evidence) between the two groups.We were unable to analyse mesh-related infections, quality of life, and rehospitalisation rate due to sparse data or because the outcome was not reported in the included studies.

AUTHORS' CONCLUSIONS

This Cochrane Review included 10 RCTs with a total of 844 participants. The review demonstrated a reduction in the incidence of parastomal hernia in people who had a prophylactic synthetic mesh placed at the time of the index operation compared to a standard ostomy formation. However, our confidence in this estimate is low due to the presence of a large degree of clinical heterogeneity, as well as high variability in follow-up duration and technique of parastomal herniation detection. We found the rate of stoma-related infection to be similar in both the intervention and control groups.

Laparoscopic repair for parastomal hernia with ongoing barbed suture followed by sandwich-technique: 'Sandwich-plus-technique'

The incidence of parastomal hernias after a permanent stoma is between 50% and 80% depending on the type of stoma, the definition of the hernia (clinical or radiological), and the length of the follow-up. Surgical therapy is complex and involves several techniques with different recurrence rates. We present three cases where we have closed the hernia gap with continuous, non-resorbable, self-retaining sutures with subsequent use of the sandwich technique (’Sandwich-plus-technique’). There were pronounced parastomal hernias in three female patients (mean age was 72 years and the range was 63–78 years) with permanent colostomata. After laparoscopic adhesiolysis, the closure of the hernia defect was completed with ongoing, barbed non-resorbable 1-0 sutures (polybutester) followed by the sandwich technique. There were no intraoperative complications and currently no clinical or radiological evidence for recurrences of the parastomal hernia. Closure of the hernia gap leads to the additional reconstruction of the lateral abdominal wall, resulting in a larger contact surface for integration of the keyhole mesh and thus prior to implantation of the Sugarbaker mesh. The laparoscopic augmentation of large parastomal hernias using the ‘Sandwich-plus-technique’ is technically complex but achieves very good results in our case series. Further studies and long-term results should prove that the low recurrence rate of the sandwich technique can be further reduced.

Clinical outcomes after parastomal hernia repair with a polyester monofilament composite mesh: a cohort study of 79 consecutive patients

PURPOSE

Different techniques and mesh materials are used in parastomal hernia repair with recently reported recurrence rates ranging from 10 to 28%. The aim of this cohort study was to examine the risk of recurrence and chronic pain after Sugarbaker or keyhole parastomal hernia repair with intraperitoneal placement of a polyester monofilament macroporous composite mesh.

METHODS

Data on all patients undergoing parastomal hernia repair with Parietex™ Composite Parastomal Mesh at our institution during a 4-year period were examined. Patients with urostomy were excluded. A team of three experienced surgeons performed all repairs. Follow-up including physical examination was done after 10 days, 6 and 12 months, and hereafter as annual structured telephone interviews. Patients suspected of hernia recurrence were offered computed tomography scan. Chronic pain was defined as pain requiring out-patient visit(s) and/or regular use of analgesics.

RESULTS

79 patients (Sugarbaker, n = 69; keyhole, n = 10) were included. Of those, 72 procedures were performed laparoscopically and seven by open technique. Two patients were reoperated within 30 days with removal of the mesh. In total, seven (9%) patients had parastomal hernia recurrence (reoperation, n = 3; conservative management, n = 4) during follow-up of median 12 months (range 0-49 months). In univariable logistic analyses, type of stoma was associated with recurrence (ileostomy 28% vs colostomy 3%, p = 0.007). Three patients (4%) reported chronic pain.

CONCLUSION

In this study, we found low rates of recurrence and chronic pain following parastomal hernia repair using intraperitoneal reinforcement with a polyester monofilament composite mesh.

European Hernia Society guidelines on prevention and treatment of parastomal hernias

BACKGROUND

International guidelines on the prevention and treatment of parastomal hernias are lacking. The European Hernia Society therefore implemented a Clinical Practice Guideline development project.

METHODS

The guidelines development group consisted of general, hernia and colorectal surgeons, a biostatistician and a biologist, from 14 European countries. These guidelines conformed to the AGREE II standards and the GRADE methodology. The databases of MEDLINE, CINAHL, CENTRAL and the gray literature through OpenGrey were searched. Quality assessment was performed using Scottish Intercollegiate Guidelines Network checklists. The guidelines were presented at the 38th European Hernia Society Congress and each key question was evaluated in a consensus voting of congress participants.

RESULTS

End colostomy is associated with a higher incidence of parastomal hernia, compared to other types of stomas. Clinical examination is necessary for the diagnosis of parastomal hernia, whereas computed tomography scan or ultrasonography may be performed in cases of diagnostic uncertainty. Currently available classifications are not validated; however, we suggest the use of the European Hernia Society classification for uniform research reporting. There is insufficient evidence on the policy of watchful waiting, the route and location of stoma construction, and the size of the aperture. The use of a prophylactic synthetic non-absorbable mesh upon construction of an end colostomy is strongly recommended. No such recommendation can be made for other types of stomas at present. It is strongly recommended to avoid performing a suture repair for elective parastomal hernia. So far, there is no sufficient comparative evidence on specific techniques, open or laparoscopic surgery and specific mesh types. However, a mesh without a hole is suggested in preference to a keyhole mesh when laparoscopic repair is performed.

CONCLUSION

An evidence-based approach to the diagnosis and management of parastomal hernias reveals the lack of evidence on several topics, which need to be addressed by multicenter trials. Parastomal hernia prevention using a prophylactic mesh for end colostomies reduces parastomal herniation. Clinical outcomes should be audited and adverse events must be reported.

Open Retromuscular Repair of Parastomal Hernias with Synthetic Mesh

Parastomal hernias (PHs) cause significant morbidity in patients with permanent ostomies, and several laparoscopic and open repair techniques have been described. We report our experience with open retromuscular repair of PHs using permanent synthetic mesh. A prospectively maintained database was retrospectively reviewed to identify patients undergoing PH repair. Primary outcomes are surgical site occurrence, surgical site infection (SSI), and hernia recurrence. Variables were analyzed using Pearson's χ2 test or Fisher's exact test. Values of P < 0.05 were considered significant. Forty-six patients underwent retromuscular PH repair with permanent synthetic mesh. There were 26 patients with colostomies and 20 with ileostomies. All the patients were repaired using a keyhole retromuscular technique and direct passage of stoma through mesh. Transversus abdominis release was performed in 65.2 per cent of cases. Permanent synthetic polypropylene mesh was used in all cases. Surgical site occurrence occurred in 47.8 per cent of patients, SSI in 17.4 per cent, and hernia recurrence in 21.7 per cent. Resiting the stoma yielded the highest rate of SSI (40%) compared with leaving the stoma in situ (11.8%) or rematuring the stoma (0%; P = 0.011). Open keyhole retromuscular PH repair of PH with permanent synthetic mesh is safe, effective, and durable.

Laparoscopic repair of parastomal hernia

Parastomal hernia is one of the most common long-term complications after abdominal ostomy. Surgical treatment for parastomal hernia is the only cure but a fairly difficult field because of the problems of infection, effects, complications and recurrence. Laparoscopic repair operations are good choices for Parastomal hernia because of their mini-invasive nature and confirmed effects. There are several major laparoscopic procedures for parastomal hernioplasty. The indications, technical details and complications of them will be introduced and discussed in this article.

Parastomal Hernia: Avoidance and Treatment in the 21st Century

Despite medical and surgical advances leading to increased ability to restore or preserve gastrointestinal continuity, creation of stomas remains a common surgical procedure. Every ostomy results in a risk for subsequent parastomal herniation, which in turn may reduce quality of life and increase health care expenditures. Recent evidence-supported practices such as utilization of prophylactic reinforcement, attention to stoma placement, and laparoscopic-based stoma repairs with mesh provide opportunities to both prevent and successfully treat parastomal hernias.

Laparoscopic repair for recurrent parastomal hernia of an end stoma using the sandwich technique while preserving an ileal conduit: A case report

•

This is a quite rare case report of laparoscopic repair for recurrent parastomal hernia in a patient with an ileal conduit.

•

Laparoscopic sandwich technique is to combine the keyhole and Sugarbaker techniques.

•

Laparoscopic sandwich technique can be useful for parastomal hernia.

Introduction

Parastomal hernia is a common complication following stoma creation. The surgical approaches included local repair by suture, stoma relocation and mesh-based techniques; but none has been able to provide satisfactory results.

Presentation of case

A 60-year-old asian female was referred complaining of abdominal pain and constipation caused by recurrent parastomal hernia of an end stoma. She had undergone total cystectomy with creation of an ileal conduit at the age of 53 years, and laparoscopic sigmoid colostomy at the age of 55 years. Parastomal hernia of an end stoma had developed postoperatively, and she had undergone recreation of colostomy at the same place with fasciorrhaphy at the age of 59 years, but parastomal hernia recurred 6 months later because of split fascia sutures. Laparoscopic repair for recurrent parastomal hernia was conducted using the sandwich technique while preserving an ileal conduit. The patient has been followed postoperatively for more than 3 years without any sign of recurrence.

Discussion

Although further cases are required to get definitive conclusions, we suppose that the laparoscopic sandwich technique can be useful for parastomal hernia.

Conclusion

We herein report a case of recurrent parastomal hernia treated laparoscopically while preserving an ileal conduit using the sandwich technique which combines the keyhole and Sugarbaker techniques. This is a quite rare case report of laparoscopic repair for recurrent parastomal hernia in a patient with an ileal conduit.

Single-port parastomal hernia repair by using 3-D textile implants

Background:

Parastomal hernias (PSHs) are a frequent complication and remain a surgical challenge. We present a new option for single-port PSH repair with equilateral stoma relocation using preshaped, prosthetic 3-dimensional implants and flat mesh insertion in intraperitoneal onlay placement for additional augmentation of the abdominal wall.

Methods:

We describe our novel technique in detail and performed an analysis of prospectively collected data from patients who underwent single-port PSH repair, focusing on feasibility, conversions, and complications.

Results:

From September 2013 to January 2014, 9 patients with symptomatic PSHs were included. Two conversions to reduced-port laparoscopy using a second 3-mm trocar were required because of difficult adhesiolysis, dissection, and reduction of the hernia sac content. No major intra- or postoperative complications or reoperations were encountered. One patient incurred a peristomal wound healing defect that could be treated conservatively.

Conclusion:

We found that single-port PSH repair using preshaped, elastic 3-dimensional devices and additional flat mesh repair of the abdominal wall is feasible, safe, and beneficial, relating to optimal coverage of unstable stoma edges with wide overlap to all sides and simultaneous augmentation of the midline in the IPOM technique. The stoma relocation enables prolapse treatment and prevention. The features of a modular and rotatable multichannel port system offer benefits in clear dissection ongoing from a single port. Long-term follow-up data on an adequate number of patients are awaited to examine efficacy.

Parastomal hernia: a growing problem with new solutions

Parastomal hernia is one of the most common complications following stoma creation and its prevalence is only expected to increase. It often leads to a decrease in the quality of life for patients due to discomfort, pain, frequent ostomy appliance leakage, or peristomal skin irritation and can result in significantly increased healthcare costs. Surgical technique for parastomal hernia repair has evolved significantly over the past two decades with the introduction of new types of mesh and laparoscopic procedures. The use of prophylactic mesh in high-risk patients at the time of stoma creation has gained attention in lieu of several promising studies that have emerged in the recent days. This review will attempt to demonstrate the burden that parastomal hernias present to patients, surgeons, and the healthcare system and also provide an overview of the current management and surgical techniques at both preventing and treating parastomal hernias.

Parastomal hernia repair and reinforcement: the role of biologic and synthetic materials

Parastomal hernia is a prevalent problem and treatment can pose difficulties due to significant rates of recurrence and morbidities of the repair. The current standard of care is to perform parastomal hernia repair with mesh whenever possible. There exist multiple options for mesh reinforcement (biologic and synthetic) as well as surgical techniques, to include type of repair (keyhole and Sugarbaker) and position of mesh placement (onlay, sublay, or intraperitoneal). The sublay and intraperitoneal positions have been shown to be superior with a lower incidence of recurrence. This procedure may be performed open or laparoscopically, both having similar recurrence and morbidity results. Prophylactic mesh placement at the time of stoma formation has been shown to significantly decrease the rates of parastomal hernia formation.
