An innovative reconstruction of an enbloc resected composite giant chest and abdominal wall chondrosarcoma with 3D-composite mesh

BACKGROUND

Chest wall chondrosarcomas, although common, pose unique challenges due to their aggressive nature, rarity of abdominal wall involvement, and propensity for recurrence. We highlight the critical role of meticulous surgical planning, multidisciplinary collaboration, and innovative reconstruction techniques in achieving optimal outcomes for patients with composite giant chest and abdominal wall chondrosarcoma.

CASE PRESENTATION

A 38-year-old female patient presented with progressive left chest and abdominal wall swelling for two years; on evaluation had a large lobulated lytic lesion arising from the left ninth rib, scalloping eighth and tenth ribs measuring 13.34 × 8.92 × 10.71 cm (anteroposterior/transverse/craniocaudal diameter) diagnosed with chondrosarcoma grade 2. A three-dimensional (3D) composite mesh was designed based on computed tomography using virtual surgical planning and computer-assisted design and manufacturing technology. She underwent wide local excision and reconstruction of the chest and abdominal wall with 3D-composite mesh under general anesthesia. The postoperative condition was uneventful, with no recurrence at 12 months follow-up.

CONCLUSION

A 3D-composite mesh facilitates patient-specific, durable, and cost-effective chest and abdominal wall reconstruction.

Update in Transvaginal Grafts: The Role of Lightweight Meshes, Biologics, and Hybrid Grafts in Pelvic Organ Prolapse Surgery

Transvaginal mesh/grafts have been popularized over the past 20 years in an attempt to improve the longevity of traditional vaginal pelvic organ prolapse (POP) surgery. Several national bodies have concluded that the proposed benefits of mesh/graft implantation are outweighed by the significant increase in surgery complications related to these products. As a consequence mesh products for vaginal POP surgery have been withdrawn from use in many countries. This article is a narrative review of newer mesh and graft products including lightweight polypropylene mesh products, biological grafts, hybrid grafts, and tissue engineered grafts.

Complex giant incisional hernia repair with intraperitoneal mesh: A case report

Introduction and importance

An incisional hernia is one of the most frequent complications after abdominal surgery, with an estimated incidence of 2-20% after midline laparotomy. They are often caused by poor wound healing. We present the case of a complex giant incisional hernia that was repaired by implanting an intraperitoneal mesh.

Case presentation

A 63-year-old man with obesity, hypertension, and multiple previous laparotomies, who developed a complex giant incisional hernia (xipho-pubic > 10 cm wide). An open technique repair was decided with the introduction of a large mesh (Parietex ™ Composite) in an intraperitoneal position, covering a 25 × 16 cm hernial ring. After two years, the patient continues to be followed due to a low-output distal enterocutaneous fistula.

Clinical discussion

Currently, there is no technique or approach that has become a gold standard for ventral incisional hernia repair. The introduction of an intraperitoneal mesh with two surfaces by laparotomy is recommended when there are contraindications for laparoscopic surgery, for example in obese patients, and patients with multiple previous laparotomies. However, it has been reported to be a complex technique with an enterocutaneous fistula rate of 0.3-4%.

Conclusion

The introduction of a composite mesh represents an alternative surgical technique for the repair of giant incisional hernias.

Complete migration of a composite mesh into small bowel incidentally found during laparotomy for colectomy in an asymptomatic patient: a case report

Background

Composite meshes are used for incisional hernia repair because they enable intraperitoneal mesh placement due to their dorsal surface, which is made of inert material. We report, for the first time, to our knowledge, a case of composite mesh migration detected incidentally during a laparotomy for colon cancer in an asymptomatic patient.

Case presentation

Our patient was a 71-year-old South Asian man who underwent ventral mesh repair following a postoperative complication after right hemicolectomy for colon cancer. The patient was diagnosed with a metachronous sigmoid cancer 5 years later, for which he underwent laparotomy. During laparotomy, a migrated mesh was incidentally found and extracted from his proximal ileum without any evidence of abscess or fistula formation.

Conclusion

To our knowledge, this is the first report of an incidentally found migrated composite mesh from a bowel lumen in an asymptomatic patient.

Case report of traumatic intrapericardial diaphragmatic hernia: Laparoscopic composite mesh repair and literature review

•

Post-traumatic rupture of the diaphragm with herniation of abdominal viscera into the pericardium is a rare injury.

•

Delayed diagnosis of Intrapericardial diaphragmatic hernia does not preclude laparoscopic repair.

•

Repair of large defect with composite mesh reduces the risk of adhesions, infection and erosion of nearby viscera.

Introduction

Traumatic rupture of the diaphragm with herniation of abdominal viscera into the pericardium is a rare injury. We present a case of intrapericardial diaphragmatic hernia after one year of thoracoabdominal trauma. This case is the 106th in the literature and only the fifth treated by the laparoscopic approach including this case. After case presentation, we will discuss post-traumatic intrapericardial diaphragmatic hernias by reviewing the literature.

Case presentation

A 48-year-old male presented to our outpatient clinic with a history of thoracoabdominal trauma due to a motor vehicle accident one year ago. The patient complained from abdominal pain and constipation over the last year. After a thorough history and physical examination, thoracoabdominal computed tomography (CT) was performed. The CT scan revealed herniation of the transverse colon and omentum through a large anterior diaphragmatic defect into the pericardial sac. Laparoscopic composite mesh repair was done. The patient had an uneventful postoperative course and was discharged home on the second postoperative day. The patient was asymptomatic at regular follow-up six months postoperatively.

Conclusion

Late presentation of intrapericardial diaphragmatic hernia is rare. Chest computed tomography is the most useful diagnostic tool. Delayed diagnosis of Intrapericardial diaphragmatic hernia does not preclude laparoscopic repair by primary closure or with mesh according to the size of the defect.

Hybrid: Evolving techniques in laparoscopic ventral hernia mesh repair

Introduction

Laparoscopic repair is now the treatment of choice for most cases of ventral/incisional hernia. Although the technique has undergone many refinements, there is no standard technique for difficult or complicated hernias.

Aim

The aim of this study was to show the different innovative methods used to treat difficult ventral hernia through hybrid techniques.

Materials and Methods

A total of 75 (n = 75) patients underwent Laparoscopic Ventral Hernia Hybrid Mesh Repair (LVHHMR) by our surgical unit between January 2014 and December 2016. Three different techniques of repairing the defects were used. Mesh fixation time, post-operative pain score (visual analogue score) and follow-up for pain and recurrence (at 6 months, 12 months and 24 months) were recorded and analysed.

Results

Out of 75 patients (20 men and 55 women), the median age was 45 years and body mass index of the patients was 25-35. Types of hernias operated were paraumbilical hernias, incisional and recurrent hernias. The techniques used were (1) laparoscopic adhesiolysis, open sac excision with closure of defect and laparoscopic mesh placement, (2) laparoscopic adhesiolysis, omphalectomy with closure of defect and laparoscopic mesh placement and (3) open adhesiolysis, sac excision with closure of defect and laparoscopic mesh placement. Five patients required analgesics for 48 h. No patients complained of pain at follow-ups (1 month, 6 months, 12 months and 24 months). Mean hospital stay postoperatively was 2-3 days.

Conclusion

LVHHMR is safe and feasible approach for complicated/difficult ventral hernias. However, further larger studies are required to establish these methods as gold standard.

Laparoscopic Mesh Repair for Perineal Hernia after En Bloc Resection of an Aggressive Angiomyxoma Using a Modified Sacral Colpopexy Technique

STUDY OBJECTIVE

To demonstrate laparoscopic mesh repair of perineal hernia (PH) by a modified sacral colpopexy technique.

DESIGN

Step-by-step demonstration of the technique used for the surgical repair of PH after gynecologic surgery.

SETTING

PH is defined as a pelvic floor defect through which the intra-abdominal viscera may protrude [1]. The reported incidence of PH ranges from 0.6% to 3%, and it generally occurs after rectal or prostate surgery [2]. Owing to its low incidence, there is no standard procedure to treat PH [3]. Herein, we demonstrate a successful case of PH treatment with a composite mesh (Dual Mesh; W. L. Gore & Associates, Newark, DE) after gynecologic surgery by a modified laparoscopic sacral colpopexy technique, which was approved by our institutional review board.

INTERVENTIONS

The patient had undergone extralevator abdominoperineal excision for an aggressive angiomyxoma and developed a sigmoid colon-protrudent PH after the surgery [4]. The patient suffered from defecatory dysfunction and dysmenorrhea. A total laparoscopic hysterectomy, bilateral salpingo-oophorectomy, and mesh repair of the PH were performed at 2 years after the primary surgery, and they were successful without any intra- or postoperative complications. Because the pelvic floor defect was too large to secure the mesh by a simple placement, we applied the modified sacral colpopexy technique using 2-0 proline (ETHICON, Tokyo, Japan) to cover and support this defect. At 12 months after the second surgery, there was no sign of recurrence of PH and aggressive angiomyxoma, and the preoperative symptoms had diminished.

CONCLUSION

Laparoscopic mesh repair by the modified sacral colpopexy technique is safe and effective to manage PH.

Long-term clinical experience with laparoscopic ventral hernia repair using a ParietexTM composite mesh in severely obese and non-severe obese patients: a single center cohort study

Background: The treatment of incisional and ventral hernias is associated with significant complications and recurrences, especially in severely obese patients. Recent studies have shown a reduced rate of surgical site infections and length of hospital stay in severely obese patients undergoing a laparoscopic ventral hernia repair.Aim: This study aims to describe the clinical experience in terms of efficacy and safety with laparoscopic ventral hernia repair using the ParietexTM Composite mesh (Covidien Sofradim Production, Trevoux, France) in severely obese patients (body mass index ≥35) compared with non-severe obese patients in a seven-year single-center cohort.Material and methods: All patients with a primary ventral or incisional hernia admitted to our hospital from 2006 until December 2012 who underwent a laparoscopic repair with the Parietex Composite mesh were included in this study. Pain scores using a numeric rating were collected prospectively 24-48 hours postoperatively. Patient data were retrospectively collected.Results: A total number of 210 patients were included; 173 with a BMI <35 and 37 with a BMI ≥35. Mean follow-up was 31 months. No statistically significant differences were found with regard to operation time, hospital stay, use of analgesics and postoperative complications. The long-term follow up recurrence rate in non-severely obese patients was 13% compared to 16% in severely obese patients (p = .60).Conclusion: Laparoscopic ventral and incisional hernia repair using the Parietex Composite mesh is feasible and safe in severely obese patients compared to non-severely obese patients.

Sirolimus-coated, poly(L-lactic acid)-modified polypropylene mesh with minimal intra-peritoneal adhesion formation in a rat model

PURPOSE

This study evaluated the manufacturing method and anti-adhesion properties of a new composite mesh in the rat model, which was made from sirolimus (SRL) grafts on a poly(L-lactic acid) (PLLA)-modified polypropylene (PP) hernia mesh.

METHODS

PLLA was first grafted onto argon-plasma-treated native PP mesh through catalysis of stannous chloride. SRL was grafted onto the surface of PP-PLLA meshes using catalysis of 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (EDC) and 4-dimethylaminopyridine (DMAP) in a CH₂Cl₂ solvent. Sprague-Dawley female rats received either SRL-coated meshes, PP-PLLA meshes, or native PP meshes to repair abdominal wall defects. At different intervals, rats were euthanized by a lethal dose of chloral hydrate and adhesion area and tenacity were evaluated. Sections of the mesh with adjacent tissues were assessed histologically.

RESULTS

Attenuated total reflection Fourier transformed infrared (ATR-FTIR) spectroscopy indicated the existence of a C=O group absorption peak (1724.1 cm^-1), and scanning electron microscope morphological analysis indicated that the surface of the PP mesh was covered with SRL. Compared to the native PP meshes and PP-PLLA meshes, SRL-coated meshes demonstrated the greatest ability to decrease the formation of adhesions (P < 0.05) and inflammation.

CONCLUSIONS

The SRL-coated composite mesh showed minimal formation of intra-abdominal adhesions in a rat model of abdominal wall defect repair.

[Effects of flap or myocutaneous flap combined with fascia lata or composite mesh on repairing severe high-voltage electrical burn wounds in abdomen of patients]

Objective: To investigate the effects of flap or myocutaneous flap combined with fascia lata or composite mesh on repairing wounds in abdomen of patients with severe high-voltage electrical burn. Methods: From January 2010 to May 2017, 11 patients with severe high-voltage electrical burn in abdomen were hospitalized in our burn wards. In 3 hours to 7 days after burn, operation was performed when patients were in stable condition. After debridement, intestines with necrosis or perforation in 4 patients with peritoneal defects were resected and intestinal anastomosis was performed. The size of abdominal wounds after debridement ranged from 13 cm×9 cm to 41 cm×32 cm. Five patients were treated with rectus abdominis myocutaneous flap and size of which ranged from 14 cm×10 cm to 30 cm×17 cm. Among the above 5 patients, 4 patients with peritoneal defects used composite mesh of 25 cm×20 cm to enhance abdominal wall. Three patients were treated with tensor fascia lata myocutaneous flap, and size of the flap ranged from 24 cm×10 cm to 27 cm×13 cm. Three patients were treated with anterolateral thigh flap with fascia lata, and one of them was treated with the lobulated flap; size of the flap ranged from 18 cm×13 cm to 25 cm×15 cm. The later 6 patients used fascia lata of flap to enhance abdominal wall. The donor sites were sutured directly or repaired with intermediate split-thickness skin graft of thigh. Results: After operation, flaps or myocutaneous flaps of patients were survived, and strength of abdominal wall recovered. During follow-up of 6 month to 1 year, flaps or myocutaneous flaps were in good appearance, with no ankylenteron or abdominal wall hernia. Conclusions: Flap or myocutaneous flap combined with fascia lata or composite mesh can achieve good effects on repairing severe high-voltage electrical burn wounds in abdomen.

Mesh erosion to urinary bladder causing fistulation to abdominal wall resulting in necrotizing fasciitis: A case report of late complication of incisional hernia

•

Incisional hernia is not an uncommon complication after abdominal operation.

•

Mesh migration and erosion causing vesico-cutaneous fistula and subsequent necrotizing fasciitis is uncommon.

•

We hereby report a case of abdominal wall necrotizing fasciitis 21 months after laparoscopic incisional hernia repair in lower midline with dual mesh, due to mesh migration and erosion into urinary bladder, resulting in fistulation between bladder and abdominal wall.

•

Mesh erosion to viscera can cause severe complication. Its risk should be balanced and discussed with patient with full consent.

Introduction

Incisional hernia is not an uncommon complication after abdominal operation, and laparoscopic ventral hernia repair with mesh is commonly performed nowadays. It is thought to have less complication compare to the traditional open repair, yet late complication is still observed occasionally and can be disastrous.

Case report

We hereby report a case of abdominal wall necrotizing fasciitis 21 months after laparoscopic incisional hernia repair in lower midline with dual mesh, due to mesh migration and erosion into urinary bladder, resulting in fistulation between bladder and abdominal wall. Repeated debridement and removal of mesh was required for sepsis control and the patient required intensive care support due to multi-organ failure. Subsequent repair of urinary bladder and abdominoplasty was performed after condition stabilized.

Conclusion

This case was the first reported incident with bladder erosion by dual mesh causing vesico-cutaneous fistula complicated with necrotizing fasciitis. Although dual mesh theoretically reduces the risk of mesh erosion, mesh erosion to viscera can still happen and cause severe complication. Its risk should be balanced and discussed with patient with full consent.

Resection and reconstruction following recurrent malignant phyllodes-Case report and review of literature

INTRODUCTION

Phyllodes tumors are uncommon biphasic fibroepithelial neoplasms of the breast of varying malignant potential occurring in middle aged women. They exhibit diverse biological behavior. Margin free excision is the mainstay of treatment.

CASE PRESENTATION

A 27 year-old lady was referred with a painless ulceroproliferative right breast lesion which had rapidly progressed over six months. Three years back, she had been diagnosed with a borderline phyllodes tumor and underwent a wide local excision followed by a right mastectomy for recurrence. The resection margins were positive hence she underwent postoperative radiation. We performed a radical resection of the chest wall and reconstruction using a composite mesh (inner PTFE and outer vypro), pedicled latissimus dorsi flap and a split skin graft for the recurrent malignant tumor. She recovered uneventfully thereafter.

DISCUSSION

Malignant phyllodes tumor is uncommon and treatment principles are from case reports and retrospective studies. Aggressive resection of the lesion and reconstruction of the chest wall with bone cement and two meshes-a composite mesh (inner layer -polytetrafluroethylene and outer layer of polypropylene) and a Vypro mesh is a possibility. This case highlights the challenges encountered in managing these patients and presents a radical solution.

CONCLUSION

Treatment of phyllodes tumor necessitates adequate excision of the tumor and adjacent tissues to ensure tumor free margins. Pathological evolution from intermediate to malignant histology may be exhibited. A full-thickness chest wall resection and reconstruction although radical is a feasible option as these tumors rarely respond to other modalities of cancer management.

Composite mesh and gluteal fasciocutaneous rotation flap for perineal hernia repair after abdominoperineal resection: a novel technique

Perineal hernia is an uncommon complication following abdominoperineal rectum resection. Several surgical procedures have been proposed for perineal hernia repair, including perineal, laparoscopic and abdominal approaches. Repair techniques can be classified into primary suture techniques, mesh placements and repairs with autogenous tissue. We report a 68-year-old man with a perineal hernia, who underwent a pelvic floor reconstruction with a transperineal composite mesh and a gluteal fasciocutaneous rotation flap. We conclude that a combined approach with transperineal mesh reconstruction and gluteal fasciocutaneous flap could be an alternative choice in perineal hernia repair after abdominoperineal resection.

Surgical treatment of large incisional hernias with intraperitoneal composite mesh: a cohort study

PURPOSE

Patients with large incisional hernias have significant morbidity and their management is a challenge for the surgical team because of the large abdominal wall involvement. The choice of surgical technique is still controversial. The purpose of this study is to analyze the predictive factors for recurrence after intraperitoneal mesh repair in patients with large incisional hernias.

METHODS

A retrospective cohort observational study with a prospectively collected database was performed in the Hospital Clinico San Carlos (Madrid, Spain). All consecutive patients operated on from January 2009 to December 2014 with incisional hernia of 10 or more centimeters in its transverse diameter were included. An intraperitoneal repair with a composite mesh fixed with discontinuous absorbable suture and fibrin sealant was performed. Demographic data, comorbidities, and early and long term outcomes were analyzed. The primary outcome was the presence of recurrence.

RESULTS

One hundred and twenty patients were included. Mean age was 63.3 years (SD 12.9) and sex ratio was 1.4:1. Seventy-two patients (60%) were ASA III-IV. Forty-five patients (37.5%) had recurrent ventral hernias. Mean defect size was 14.7 cm (SD 3.21) of width. Overall postoperative morbidity rate was 25%. Median hospital stay was 6 days (IQR 4-8). Recurrence rate was 8.3%, after a median follow-up of 16 months (IQR 10-25). Multivariate analysis showed significant association between ASA III-IV, use of Composix Kugel™ mesh, superficial surgical site infection, and the presence of recurrence.

CONCLUSIONS

The recurrence rate after intraperitoneal mesh repair in patients with large incisional hernias might be associated with ASA III-IV, use of Composix Kugel™ mesh, and superficial surgical site infection.

Polypropylene-based composite mesh versus standard polypropylene mesh in the reconstruction of complicated large abdominal wall hernias: a prospective randomized study

PURPOSE

To compare polypropylene mesh positioned onlay supported by omentum and/or peritoneum versus inlay implantation of polypropylene-based composite mesh in patients with complicated wide-defect ventral hernias.

METHODS

This was a prospective randomized study carried out on 60 patients presenting with complicated large ventral hernia in the period from January 2012 to January 2016 in the department of Gastrointestinal Surgery unit and Surgical Emergency of the Main Alexandria University Hospital, Egypt. Large hernia had an abdominal wall defect that could not be closed. Patients were divided into two groups of 30 patients according to the type of mesh used to deal with the large abdominal wall defect.

RESULTS

The study included 38 women (63.3 %) and 22 men (37.7 %); their mean age was 46.5 years (range, 25-70). Complicated incisional hernia was the commonest presentation (56.7 %).The operative and mesh fixation times were longer in the polypropylene group. Seven wound infections and two recurrences were encountered in the propylene group. Mean follow-up was 28.7 months (2-48 months).

CONCLUSIONS

Composite mesh provided, in one session, satisfactory results in patients with complicated large ventral hernia. The procedure is safe and effective in lowering operative time with a trend of low wound complication and recurrence rates.

Rapid reperitonealization and wound healing in a preclinical model of abdominal trauma repair with a composite mesh

PURPOSE

Peritoneal tissue healing is characterized by the simultaneous repopulation of mesothelial cells and the formation of neoperitoneum. Despite the common use of mesh products for abdominal wall repair, there are few investigations of how these materials may impact the peritoneal healing process. Here, we utilized an animal model of abdominal trauma to specifically investigate the peritoneal healing process in conjunction with a composite (poliglecaprone 25-coated polypropylene) mesh.

METHODS

Abdominal wall injury was simulated in New Zealand White rabbits and peritoneal tissue was covered with composite mesh and fixed with peripheral sutures. Animals were sacrificed at regular intervals (up to 28 days) for macroscopic and microscopic evaluation.

RESULTS

Mesothelial cells were consistently identified on the surface of the central areas of the implanted mesh as early as 3-5 days after implantation. From day 7 onward, the entire mesh surface was covered by neoperitoneum which matured over the remaining study intervals. Fibroblast ingrowth of the mesh was apparent by day 5 and increased over time, concurrent with fragmentation of the film on the composite mesh.

CONCLUSIONS

These results suggest that composite mesh products used for abdominal wall repair do not significantly delay mesothelial repopulation. Study results also support the hypothesis that mesothelial cells involved in healing are derived, at least in part in this model, from free-floating precursor cells located within the peritoneal cavity.

Laparoscopic repair of Morgagni hernia with composite mesh in an elderly woman: Report of a case

A 78-year-old woman was admitted to another hospital with vomiting. Chest X-ray showed an abnormal shadow in the lower right lung field, and CT indicated a Morgagni hernia containing the stomach and transverse colon. The patient was transferred to our hospital and underwent laparoscopic surgery. After the hernia contents were repositioned into the abdominal cavity, we repaired the hernia orifice with a prosthetic mesh to achieve a tension-free repair. There were no complications after the surgery, and there has been no recurrence. The patient has remained free of clinical symptoms since 10 months after the surgery. Laparoscopic repair with a prosthetic mesh for Morgagni hernia is a simple and safety procedure for elderly patients.

Tissue integration and inflammatory reaction in full-thickness abdominal wall repair using an innovative composite mesh

PURPOSE

When composite meshes are used in abdominal wall repair, seroma formation may persist and delay the desired integration leading to recurrence. This study compares tissue integration and inflammatory response in abdominal wall repair with composites with different absorbable synthetic barriers.

METHODS

Full-thickness defects created in the abdominal wall of rabbits were repaired using polypropylene prosthesis or the following composites: Physiomesh™ (Phy); Ventralight™ (Vent) and "new composite mesh" (Ncm) not yet used clinically in humans. The collected seroma was evaluated for IFN-γ/IL-4 by ELISA. Tissue integration, anti- (IL-13/TGFβ-1/IL-10/IL-4) and pro-inflammatory (TNF-α/IL-6/IFN-γ/VEGF) cytokine mRNA expression and TGFβ/VEGF immunolabeling were evaluated at 14 and 90 days post-implant.

RESULTS

Seroma was observed in 10 of 12 Phy/Vent and 4 of 12 Ncm. Wound fluid IFN-γ showed a time-dependent significant increase in Vent and tendency to decrease in Ncm, while all composites exhibited IL-4 upward trend. Prostheses were fully infiltrated by an organized connective tissue at end time although the area had shown prior seroma. A stable mesothelium was developed, except in adhesion areas. Vent/Phy displayed a significant increase in TNF-α/IFN-γ-mRNA over time. Significant decrease in VEGF mRNA was observed in Phy/Ncm, while a significant increase of TGFβ-1 mRNA was evident in all composites over time. Ncm exhibited the highest TGFβ protein expression area at short term and the greatest percentage of VEGF positive vessels at end time.

CONCLUSION

Ncm could be an appropriate candidate to improve clinical outcome showing the lower development of seroma and optimal tissue integration with minimal pro-inflammatory cytokine response over time and consistent pro-wound healing cytokine expression.

Laparoscopic mesh repair of parahiatal hernia: a case report

We report a case of a primary parahiatal hernia that was repaired laparoscopically with a composite mesh. A 51-year-old woman presented with vomiting and epigastric pain. CT scan showed a giant paraesophageal hernia with intrathoracic gastric volvulus. Intraoperatively, a diaphragmatic muscular defect was found lateral to an attenuated left crus of the diaphragm, distinct from the normal esophageal hiatus. The defect ring was fibrotic, making a tension-free primary repair difficult. A laparoscopic mesh repair was performed with a composite mesh, which was covered with the hernia sac to prevent potential erosion into the esophagus or stomach. Recovery was uneventful and the patient was discharged on the 5 days postoperatively. She remained asymptomatic at subsequent follow-up. Laparoscopic repair of parahiatal hernia can be safely performed. In circumstances where a large or fibrotic defect prevents a tension-free primary repair, the use of a composite mesh can provide effective repair of the hernia.

Intra Peritoneal Polypropylene Mesh and Newer Meshes in Ventral Hernia Repair: What EBM Says?

Incisional hernias and other ventral hernias are common surgical problems. It is estimated that incisional hernia complicates about 2 % to 10 % of laparotomies. Ventral and incisional hernia repairs are among the common surgeries done by a general surgeon. It is proven beyond any doubt that suture repair of these hernias should not be done as recurrence rates are unacceptably high, some series reporting as high as 54 % on long-term follow-up. A prosthetic mesh should always be used in ventral hernia repair (VHR). Now, the polypropylene mesh (PPM) has become the prosthetic mesh of choice in the repair of hernias, including inguinal hernia. However, with the advent of laparoscopic repair where the mesh is placed intraperitoneally, concerns regarding safety of PPM are raised. Newer meshes are introduced, claiming lesser complication rate. Many types of newer meshes are available now. Newer meshes are invariably costlier than PPM by 15-20 times. Is this extra cost worth? We looked in to available literature for an answer.
