Role of Mesh in the Reinforcement of the Primary Repair of Large Hiatal Hernia

Abstract Background The incidence of hiatal hernias increases with age. Approximately 55%-60% of individuals over the age of 50 have a hiatal hernia. However, only about 9% have symptoms, and it depends on the type and competency of the lower esophageal sphincter. Aim of the Work In our study, an objective observational study was made regarding post operative short term mesh related complications possible to develop in patients underwent hiatal repair of large hiatal hernia with mesh rienforcement. Patients and Methods An observational cohort (retrospective and prospective) study regarding the post operative mesh related complications in patients who underwent Large diaphragmatic hernia repair with mesh application. The study was conducted at Ain Shams University Hospitals, Al-Demerdash, Department of General surgery. Approval of the research ethics Committee of medicine and general surgery department at faculty of medicine, Ain Shams University as well as a written informed consent from all participants was obtained. The study was conducted on 15 patients over a period of six months, starting from date of approval of the protocol by the faculty and the university committee at 10/7/2021. Results Five patients (33.3%) complained about dysphagia postoperatively. In one case, the symptoms declined spontaneously within 6 months was grade 1. Another patient successfully underwent esophageal dilatation of a stenosis 2 months postoperatively was grade 2. Up to this date, two patients (13.3%) still report mild dysphagia but maintain normal body weight were grade 3. Three cases report persistent intraabdominal discomfort without weight loss described as bloating. Two patients experienced heartburn, while another patient reported respiratory compromise in the form dyspnea due to already huge hiatal defect with lung collapse present preoperatively. Conclusion Laparoscopic large hiatal/paraesophageal hernia repair with prosthetic meshes as well as laparoscopic antireflux surgery with prosthetic hiatal closure are safe and effective procedures to prevent hiatal hernia recurrence and/or postoperative intrathoracic wrap migration, with low complication rates and mesh fixation is indicated in patients with large hiatal hernial defect > 5 cm.

TU1.9 Oesophageal manometry and ambulatory pH monitoring prior to laparoscopic anti-reflux surgery – is it a necessity? An evaluation of a newly established anti-reflux surgery service at a district general hospital

Abstract Background Laparoscopic fundoplication is an effective surgical option for patients with symptoms of reflux refractory to proton-pump inhibitor (PPI) use. Oesophageal manometry and ambulatory pH monitoring are typically advocated as part of the evaluation of gastro-oesophgeal reflux disease, when anti-reflux surgery is considered. However, the requirement for these as a mandatory procedure remains controversial, particularly in the context of large hiatus hernia or presence of endoscopic reflux oesophagitis. Methods A retrospective review of all cases performed since the inception of the anti-reflux service at a single-centre district general hospital was undertaken. All patients who underwent an elective laparoscopic anti-reflux operation were included. Data pertaining to preoperative symptoms, preoperative investigations and postoperative outcomes (resolution of symptoms and PPI cessation) was collected. Results Over the three-year period, 22 anti-reflux operations were performed, of which 17 were followed up. The mean length of follow-up was 9.5 months. Most patients (91%) had typical reflux symptoms with a large hiatus hernia or endoscopic reflux oesophagitis. Only 4 (18.2%) patients underwent oesophageal manometry and ambulatory pH monitoring—each of these had either a normal preoperative OGD or barium swallow, or atypical symptoms. Alleviation of symptoms was achieved in 14 (82.3%) patients; 9 (52.9%) of which achieved complete resolution. PPI cessation was achieved in 12 (70.1%) patients, comparable with current literature. Conclusion Anti-reflux surgery can safely be performed without routine oesophageal manometry and ambulatory pH monitoring in the context of typical symptoms, a large hiatal defect or evidence of endoscopic reflux oesophagitis, as exemplified in our newly established anti-reflux service.

Diaphragm Relaxing Incisions in Repair of Hiatal Defects—When to Relax and How to Achieve Closure

The operative challenges presented by large hiatal defects require that surgeons have an expansive armamentarium of tools with which to approach the crural closure. When crural closure cannot be achieved primarily, our experience suggests that use of diaphragm relaxing incisions can facilitate primary crural closure, contributing to decreasing the risk of recurrence following hiatal or paraesophageal hernia repair. Here, we present our method for identifying patients who would benefit from a diaphragm relaxing incision, as well as the technique for performing both a right and left diaphragm relaxing incision.

OV07 LAPAROSCOPIC HIATAL HERNIA MESH-SUTURE REPAIR

Abstract Aim “A new original laparoscopic operative technique was used to suture paraesophageal hernia (PEH) with the strips of mesh. Material and Methods The Mercilen (MercilenTM) mesh suture was used to close large hiatal hernia. The strips of mesh, instead of normal thread, were applied to close the gap between diaphragm’s crura in 12 patients with hernia defect more than 5 cm. Mesh suture were tighten as a simple laparoscopic intracorporeal knot. The surgical technique and surgical outcomes are presented. Results 12 patients underwent a laparoscopic PEH suturing with Mercilen strips of mesh. We recorded no recurrence or dysphagia at 6 and 12 months follow-up. Conclusions Mesh-sutured repairs of diaphragm’s hernia support the concepts of force distribution and resistance to suture pull through. The new original technique avoids using the sheet of mesh and enables to reduce the amount of dangerous complications connected with mesh and its fixation. Mesh-sutured closures of hiatal hernias seem to be safe and effective in tension closure of large hiatal defects. Further investigations are needed to evaluate the results. Using the mesh suture technique for the closure of large PEH, we protect the cruras from being cutting through. Besides, the mesh stripes and its knots produce tissue scarring around the esophagus making the suture line stronger.

Extraperitoneal high vaginal cuff suspension at the time of vaginal hysterectomy for advanced uterovaginal prolapse: Results of a modified McCall technique from a longitudinal clinical study.

Women with high-grade uterovaginal prolapse have a greater risk of recurrent prolapse after pelvic organ prolapse surgery. Royal College of Obstetricians and Gynaecologists guidelines have recommended sacrospinous suspension (sacrospinous fixation) at the time of vaginal hysterectomy, whenever there is a marked uterovaginal prolapse. We have modified the McCall culdoplasty by placing sutures extraperitoneally, higher and more lateral into the uterosacral/cardinal ligaments to re-support the vaginal cuff at the time of a vaginal hysterectomy. To evaluate the results of a modified technique of McCall high culdoplasty and native tissue repair at time of vaginal hysterectomy in women with advanced uterovaginal prolapse. Longitudinal clinical follow-up conducted between 2000-2018, in a tertiary urogynaecology centre for patients presenting with stage 3-4 uterovaginal prolapse, who underwent vaginal hysterectomy and modified McCall vault suspension. There were 176 cases meeting the inclusion criteria. Mean follow-up was 19.35months. There were 25 recurrences (14%) of ≥stage 2 (76% not symptomatic). Twelve of these recurrences (48%) occurred in anterior compartment, six (25%) posterior, three (12%) combined anterior/posterior, two (8%) combined posterior/central and one case had recurrence in all compartments. Only six cases (3%) required another surgical procedure for symptomatic prolapse, all with an enterocele recurrence. Our described modified McCall technique incorporates high extraperitoneal approach to apical resuspension along with closure of any existing large hiatal defects of the levator plate at the time of vaginal hysterectomy for advanced uterine prolapse has excellent outcomes and extremely low complication rates and avoids the need for sacrospinous fixation.

Preoperative Computer-Assisted Laparoscopy Planning for the Minimally Invasive Surgical Repair of Hiatal Hernia.

Minimal invasive surgical procedures such as laparoscopy are preferred over open surgery due to faster postoperative recovery, less trauma and inflammatory response, and less scarring. Laparoscopic repairs of hiatal hernias require pre-procedure planning to ensure appropriate exposure and positioning of the surgical ports for triangulation, ergonomics, instrument length and operational angles to avoid the fulcrum effect of the long and rigid instruments. We developed a novel surgical planning and navigation software, iMTECH to determine the optimal location of the skin incision and surgical instrument placement depth and angles during laparoscopic surgery. We tested the software on five cases of human hiatal hernia to assess the feasibility of the stereotactic reconstruction of anatomy and surgical planning. A whole-body CT investigation was performed for each patient, and abdominal 3D virtual models were reconstructed from the CT scans. The optical trocar access point was placed on the xipho-umbilical line. The distance on the skin between the insertion point of the optical trocar and the xiphoid process was 159.6, 155.7, 143.1, 158.3, and 149.1 mm, respectively, at a 40° elevation angle. Following the pre-procedure planning, all patients underwent successful surgical laparoscopic procedures. The user feedback was that planning software significantly improved the ergonomics, was easy to use, and particularly useful in obese patients with large hiatal defects where the insertion points could not be placed in the traditional positions. Future studies will assess the benefits of the planning system over the conventional, empirical trocar positioning method in more patients with other surgical challenges.

The use of biosynthetic mesh in giant hiatal hernia repair: is there a rationale? A 3-year single-center experience.

Reinforced prosthetic crural repair is particularly indicated for giant hiatal hernias. The rationale is to reduce the recurrence rate in the long term. The aim of our study is to evaluate the outcomes of laparoscopic giant hiatal hernia repair using a biosynthetic mesh. We retrospectively analyzed 44 patients who underwent laparoscopic mesh-reinforced hiatal closure and fundoplication using a biosynthetic material. Inclusion criterion was large hiatal defects (> 5cm). Follow-up was scheduled at 6, 12 and 36months after surgery. 44 patients (29F) with a mean age of 62years (range 14-85) and mean of BMI 24.5kg/m2 (range 21-29) underwent successful laparoscopic repair. Twenty-six (59.1%) patients had Nissen-Rossetti fundoplication, whereas 18 (40.9%) had Toupet fundoplication. Six-month questionnaire for the evaluation of symptoms was available for 43 patients (97.7%) and for 40 (90.9%) patients at 12 and 36months. Mean preoperative symptoms score analysis was 1.68 ± 0.73. Mean scores at each follow-up time were significantly improved compared to baseline (p > 0.05). Barium swallow was available in 37 patients (84.1%) at 1year after surgery. Radiologic recurrence was observed in two patients (4.5%). No patient had symptoms attributable to recurrence or required revisional surgery. There were no mesh-related complications at 3years follow-up. The use of biosynthetic mesh for crural reinforcement is associated with a low incidence of mesh-related complications and with a reasonably low recurrence rate (4.5%) at 36months. However, additional data with longer follow-up are needed to determine long-term safety and efficacy.

Laparoscopic mesh-suture hiatal hernia repair

BACKGROUND: A new original laparoscopic operative technique was used to suture paraesophageal hernia (PEH) with the strips of mesh. METHODS: The Mercilen (MercilenTM) mesh suture was used to close large hiatal hernia. The strips of mesh, instead of normal thread, were applied to close the gap between diaphragm's crura in four patients with hernia defect more than 5 cm. Mesh suture were tighten as a simple laparoscopic intracorporeal knot. The surgical technique and surgical outcomes are presented. RESULTS: Four patients underwent a laparoscopic PEH suturing with Mercilen strips of mesh. We recorded no recurrence or dysphagia at 6 and 12 months follow-up. CONCLUSIONS: Mesh-sutured repairs of diaphragm's hernia support the concepts of force distribution and resistance to suture pull through. The new original technique avoids using the sheet of mesh and enables to reduce the amount of dangerous complications connected with mesh and its fixation. Mesh-sutured closures of hiatal hernias seem to be safe and effective in tension closure of large hiatal defects. Further investigations are needed to evaluate the results.

Laparoscopic gastric fundus tamponade: a novel adaptation of the Toupet fundoplication for large paraesophageal hernia repair.

Laparoscopic repair of large paraesophageal hiatal hernia with defects too large to close primarily or greater than 8cm is technically challenging. The ideal repair remains unclear and is often debated. Utilizing the gastric fundus as an autologous patch to obliterate and tamponade large hiatal defects may offer a new solution. The aim of this study was to evaluate the short-term outcomes following partial posterior fundoplication with gastric fundus tamponade. Retrospective chart review and prospective patient follow up was conducted on patients who underwent laparoscopic hiatal hernia repair between 2015 and 2019 by a single surgeon. Basic demographics, pre-operative diagnoses, operative technique, and clinical outcomes were recorded. Fifteen patients underwent the described technique for repair of large paraesophageal hiatal hernia. All procedures were completed laparoscopically with a short post-operative length of stay (mean of 3days) and no 30-day readmissions. The majority of patients reported resolution of their pre-operative symptoms. Only one patient required surgery for emergent indications and the same patient was the only mortality in the study, which was secondary to respiratory failure, necrotizing pneumonia, and sepsis as a result of gastric volvulus and obstruction. Utilizing the gastric fundus as an autologous patch to repair large hiatal hernia may be a safe and efficacious solution with good short-term outcomes. However, further studies should be conducted to elucidate long-term results.

The use of autologous fascia lata graft in the laparoscopic reinforcement of large hiatal defect: initial observations of the surgical technique.

BackgroundEven though there is no consensus, many authors believe that in the cases of large hiatal defects, structurally altered crura and/or absence of peritoneal lining, a crural reinforcement should be performed. Reinforcement could be performed with different techniques and different type of mesh, either synthetic or biologic. The disadvantages of mesh repair include the possibility of serious complications and increased costs especially in the usage of composite or biologic mesh.MethodsThe study includes 10 cases of reinforced primary suture line of the pillars with autologous fascia lata, in elective laparoscopic repair of the giant PEH with a large hiatal defect and friable crura. After intraopreative confirmation of the large hiatal defect (hiatal surface area of more than 8 cm2) and friable crura, an autologous fascia lata graft was harvested in the usual manner and placed in on-lay fashion to reinforce the pillar suture line. We analyzed surgical technique, complications, and initial follow-up of the patients.ResultsAverage hiatal surface area (HSA) in our series was 10.6 cm2 (range 8.1 to 14.4 cm2). The average duration of operation was 203.9 min/3.4 hours (range 160–250 min). Except for a mild hematoma in the harvesting region that resolved spontaneously, there were no procedure related complications and 30 days mortality rate was zero. The average postoperative length of stay was 6.5 days (5–8 days). Out of 10 patients, 5 completed the annual follow-up visit, while 8 completed a 6- month follow-up visit. So far there is no hernia recurrence and/or problems with swallowing function. However, one patient has felt a mild discomfort in the harvested region that does not influence normal daily activities.ConclusionsAutologous fascia lata graft hiatal reinforcement represents a technically feasible, easy, and available option for the on-lay reinforcement of large hiatal defects with friable crura in the laparoscopic repair of giant PEHs.

Short-term results for laparoscopic repair of large paraesophageal hiatal hernias with Gore Bio A® mesh

BackgroundThe application of mesh-reinforced hiatal closure has resulted in a significant reduction in recurrence rates in comparison with primary suture repair. One of the most debated issues is the risk of complications related to the use of the prosthesis, such as esophageal erosion and postoperative dysphagia. The aim of this study is to present our short-terms results in the treatment of laparoscopic paraesophageal hiatal hernia (LPHH) with a synthetic polyglycolic acid:trimethylene carbonate mesh (Gore Bio A®). MethodsFrom January 2011 to December 2012, 10 patients with large paraesophageal hiatal hernias and hiatal defect over 5 cm were included. Primary simple suture of the crura and additional reinforcement with a Gore Bio A® mesh was performed. Hiatal hernia or gastroesophageal reflux disease (GERD) symptoms recurrence, dysphagia and mesh-related complications were investigated. ResultsOf the 10 patients undergoing mesh repair, there were 7 women and 3 men with a mean age of 65.5 years. All operations were completed laparoscopically. Median postoperative stay was 3 days. After a median follow-up of 20.3 months, one patient developed a recurrent hiatal hernia (10%). There were no mesh-related complications. ConclusionsThe use of Gore Bio A® mesh for the laparoscopic repair of large paraesophageal hiatal hernias is safe and with a reasonably low recurrence rate in this short-term study. Additional long-term studies with ample numbers carried out for years will be necessary to see if this synthetic mesh is not only safe but also successful in the prevention of recurrences.

Postoperative Dysphagia in Laparoscopic Paraesophageal Hernia Repair

Dysphagia following laparoscopic paraesophageal hernia repair is an uncommon but difficult problem that may be due to technical factors. We looked for an association between esophageal angulation after posterior crural repair and postoperative dysphagia. Patients undergoing paraesophageal hiatus hernia repair were identified from a prospectively maintained dedicated database. All patients underwent a standardized laparoscopic repair. Essentially the hernia sac was dissected from the mediastinum, a posterior hiatal repair was carried out with interrupted polyester sutures, and augmented with mesh on lay. A partial posterior fundoplication was then carried out. We used the number of posterior sutures as a proxy for anterior esophageal angulation. Quality-of-life data and dysphagia scores were recorded preoperatively, at 6 weeks postoperatively and 12 months postoperatively using validated instruments. Between November 2004 and September 2010, 114 consecutive patients underwent paraesophageal hiatus hernia repair. There was 1 postoperative death in the series. Median age was 67 years (interquartile range, 59 to 77 y) and 90 (79%) were female. Median hospital stay was 3 days (interquartile range, 2 to 5 y). Follow-up data were available in 87 (76%) of patients at 6 weeks and 94 (82%) of patients at 12 months postoperation. Overall, there was a significant improvement in quality of life that was sustained out to 12 months (P<0.001). Dakkak dysphagia scores were significantly improved postoperatively. Improvement was sustained out to 12 months (P<0.001). Three patients underwent endoscopic esophageal dilation for dysphagia following surgery. There was no significant correlation between the number of posterior sutures used and dysphagia outcome. Specifically there was no association with overall Dakkak scores or change in Dakkak score. Anterior angulation due to posterior hiatal repair does not result in worsening dysphagia, even in patients with large hiatal defects. A posterior repair should therefore remain the standard approach for hiatal closure.

Predictability of hiatal hernia/defect size: is there a correlation between pre- and intraoperative findings?

Closure of the esophageal hiatus is an important step during laparoscopic antireflux surgery and hiatal hernia surgery. The aim of this study was to investigate the correlation between the preoperatively determined hiatal hernia size and the intraoperative size of the esophageal hiatus. One hundred patients with documented chronic gastroesophageal reflux disease underwent laparoscopic fundoplication. All patients had been subjected to barium studies before surgery, specifically to measure the presence and size of hiatal hernia. The size of the esophageal hiatus was measured during surgery by calculating the hiatal surface area (HSA). HSA size >5cm(2) was defined as large hiatal defect. Patients were grouped according to radiologic criteria: no visible hernia (n=42), hernia size between 2 and 5cm (n=52), and >5cm (n=6). A retrospective correlation analysis between hiatal hernia size and intraoperative HSA size was undertaken. The mean radiologically predicted size of hiatal hernias was 1.81cm (range 0-6.20cm), while the interoperative measurement was 3.86cm(2) (range 1.51-12.38cm(2)). No correlation (p<0.05) was found between HSA and hiatal hernia size for all patients, and in the single radiologic groups, 11.9% (5/42) of the patients who had no hernia on preoperative X-ray study had a large hiatal defect, and 66.6% (4/6) patients with giant hiatal hernia had a HSA size <5cm(2). The study clearly demonstrates that a surgeon cannot rely on preoperative findings from the barium swallow examination, because the sensitivity of a preoperative swallow is very poor.

Acellular Dermal Graft Reinforcement at the Hiatus

The ideal technique to repair large hiatal and diaphragmatic defects remains controversial. Due to high recurrence rates with primary repair alone, attempts at crural reinforcement with various products has been investigated. Initial evaluation of synthetic mesh at the hiatus in retrospective studies led to the conclusion that there were too many serious complications with these products. The next step was to see how biologic grafts fared in this location. Beginning with porcine intestine submucosa in a laminated array and progressing through human and porcine acellular dermal matrices, multiple, retrospective studies looked at the efficacy and safety of these products. Unfortunately, most of these studies evaluated a small sample size with a relatively short follow-up period. The one study followed out to 5 years failed to show any benefit using the biologic (porcine intestinal submucosa) compared with the primary repair alone. Additional, prospective, randomized studies with ample numbers carried out for years will be necessary to see which biologic graft is not only safe but also successful in preventing recurrent herniations.

Intrathoracic gastric perforation: a late complication of an unknown postpartum recurrent hiatal hernia

Diaphragmatic hernias occurring during pregnancy are an uncommon event. In very rare occasions, the clinical situation can suddenly worsen due to obstruction, torsion or infarction of the herniated viscera. Here, we describe a challenging case of a post-partum diaphragmatic hiatus hernia complicated by intrathoracic gastric perforation. A 23-year old woman was admitted at our hospital with a syndrome characterized by epigastralgy, dyspnoea and fever. She had previously undergone a laparoscopic antireflux surgery for hiatus hernia (6 years before) and a recent (4 months) unremarkable vaginal delivery. Due to the persistence of a pelvic pain after the delivery, she had been taking pain-killers as a self-administered medication. A CT scan showed a massive left pleural effusion and a complete herniation of the stomach into the left hemithorax. After placing a chest drainage and removing up to 3000ml of brownish purulent fluid, a repeat CT scan (with water soluble contrast swallow) showed a leak at the level of the stomach. At surgery, we observed a complete intrathoracic herniation through a large diaphragmatic hiatal defect and a small well-defined gastric ulcer. A primary repair of both the stomach and the diaphragm was performed. We take the opportunity presented by this report to briefly discuss the patho-physiological mechanisms underlying this unusual complication.

Laparoscopic prosthetic hiatal reinforcement for large hiatal hernia repair

Large hiatal hernia (LHH) is defined by a hiatal defect larger than 6cm; repair is indicated whenever it becomes symptomatic. As the risk of recurrence after most techniques is relatively high, laparoscopic repair with prosthetic reinforcement of the hiatus has been proposed to reduce the recurrence rate. Our technique and outcomes are reported. Laparoscopic prosthetic hiatal reinforcement was performed in 58 patients between August 1997 and October 2009. Prolene(®), Mersilene(®), Goretex(®), and Parietex(®) were the four types of prosthetic material used. Since January 2004, the double-sided V shaped Crurasoft(®) mesh was introduced. Surgical evaluation was based on anatomical and functional criteria: the anatomical results included the presence of recurrent hiatal hernia or esophageal stricture as evaluated by an upper gastrointestinal (UGI) series; functional evaluation was based on a questionnaire concerning long-term patient satisfaction according to the Visick score. Median follow-up was 51 months. Postoperative UGI series were performed during the initial hospitalization in 37 patients: results were judged to be satisfactory. A routine follow-up UGI series was obtained at 8 months and one year in 46 patients. Two patients underwent reoperation for lower esophageal stricture at 6 months and 16 months. Forty-five patients (77.6%) were reevaluated. Of these, 29 patients (64.4%) were free of symptoms with a good quality of life, eight patients (17.7%) complained of moderate dysphagia and two patients (4.4%) had severe dysphagia. Four patients (8.9%) had moderate pyrosis while severe pyrosis requiring long term PPI treatment was observed in three patients (6.7%). No prosthesis-induced ulceration or perforation was noted. Late follow-up UGI series, performed in 21 patients, showed two patients with severe stricture and a single case of recurrence, but neither of these patients required surgical management. The addition of mesh reinforcement to surgical repair of large hiatal defects is safe and beneficial in terms of quality of life.

Laparoscopic Mesh Repair for Hiatal Hernia

We reviewed the literature to evaluate the current status of hiatal mesh repair in Western countries and introduce our procedure using ParietexTM composite mesh. Faced with large hiatal defects and a high recurrence rate, some early surgeons advocated the use of artificial material for closure of the defect. The first report of the use of a prosthetic material to reinforce crural repair was in 1960. Thereafter, some surgeons reported that mesh prosthesis-reinforced hiatus hernia repair was effective and appeared to have a low recurrence rate. Mesh hernia repair is the standard procedure to treat giant hiatal hernia in Western countries. However, this procedure is less common in Japan, and indications for mesh use have not been established. We determined the indication at our institution as follows: 1) type III hiatal hernia, 2) hiatal defect size > 5cm, and 3) weak crus that tears easily with crural repair. During the operation, we insert and use 5 trocars and return the stomach to its normal position. The hernia sac should be removed as far as possible to prevent hernia recurrence. We suture the crus and place mesh to reinforce the hiatal defect. The mesh was anchored with tacks, which allow the mesh to be easily placed. ParietexTM composite mesh, the first mesh for hiatal hernia repair introduced in Japan, is coated on 1 side with a protective collagen-based barrier to help prevent tissue attachment. The mesh is created in the shape of the hiatus to buttress the primary repair by reinforcing the approximation of the crus on either side of the esophagus. We are satisfied with this mesh because it makes hiatal repair a safe and simple procedure. In conclusion, mesh replacement in hiatal hernia repair should be promoted, and the operative indications for hiatal mesh repair should be determined in Japan.

Laparoscopic anterior hemifundoplication and hiatoplasty for the treatment of upside-down stomach: mid- and long-term results after 40 patients

Treatment of type 4 hiatal hernia using a minimally invasive approach is challenging and requires good familiarity with this technique. From October 1992 to August 2010, 40 patients with a median age of 68 years underwent laparoscopic anterior hemifundoplication surgery for upside-down stomach and were included in our prospective study. The median symptoms duration was 5 years. The leading clinical symptoms were postprandial, epigastric, or retrosternal pain (80%), heartburn (78%), regurgitation (80%), dysphagia (53%), and anemia (48%). Preoperative evaluation included blood test, chest X-ray, upper endoscopy, and barium swallow. In some patients an esophageal 24-h pH study and esophageal manometry were performed. The median follow-up was 46 months using a standardized questionnaire, including Smiley score, modified Visick score, gastrointestinal quality-of-life index (GQLI), and specific reflux symptoms score. Surgery was finished laparoscopically in 39 patients (97%). One patient had to be converted to an open procedure because of severe adhesions. Mesh hiatoplasty had to be performed in one patient due to a large hiatal defect. Median operative time was 160 min (range=90-275) and median blood loss was 5 ml (range=0-300). Seven patients (18%) presented with acute symptoms. Intraoperative technical complications occurred in four patients (10%) and nontechnical complications in two cases (5%). Median postoperative hospital stay was 5 days (range=2-17). Postoperative complications occurred in two patients (5%): one pleural effusion and one surgical emphysema. There was no mortality or symptomatic recurrence. All scores showed significant improvement and patient satisfaction. Laparoscopic treatment of type 4 hiatal hernia is safe. With respect to the quality of life, anterior hemifundoplication is highly effective.

The Evolution and Long-Term Results of Laparoscopic Antireflux Surgery for the Treatment of Gastroesophageal Reflux Disease

For nearly 2 decades, the laparoscopic correction of gastroesophageal reflux disease (GERD) has demonstrated its utility. However, the surgical technique has evolved over time, with mixed long-term results. We briefly review the evolution of antireflux surgery for the treatment of GERD, provide an update specific to the long-term efficacy of laparoscopic antireflux surgery (LARS), and analyze the factors predictive of a desirable outcome. PubMed and Medline database searches were performed to identify articles regarding the laparoscopic treatment of GERD. Emphasis was placed on randomized control trials (RCTs) and reports with follow-up >1 year. Specific parameters addressed included operative technique, resolution of symptoms, complications, quality of life, division of short gastric vessels (SGVs), mesh repair, and approximation of the crura. Those studies specifically addressing follow-up of <1 year, the pediatric or elderly population, redo fundoplication, and repair of paraesophageal hernia and short esophagus were excluded. LARS has varied in technical approach through the years. Not until recently have more long-term, objective studies become available to allow for evidenced-based appraisals. Our review of the literature found no long-term difference in the rates of heartburn, gas-bloat, antacid use, or patient satisfaction between laparoscopic Nissen and Toupet fundoplication. In addition, several studies have shown that more patients had an abnormal pH profile following laparoscopic partial as opposed to total fundoplication. Conversely, dysphagia was more common following laparoscopic total versus partial fundoplication in 50% of RCTs at 12-month follow-up, though this resolved over time, being present in only 20% with follow-up >24 months. We confirmed that preoperative factors, such as hiatal hernia, atypical symptoms, poor antacid response, body mass index (BMI), and postoperative vomiting, are potential predictors of an unsatisfactory long-term outcome. Last, no trial disfavored division of the short gastric vessels (SGVs), closure of the crura, or mesh repair for hiatal defects. LARS has significantly evolved over time. The laparoscopic total fundoplication appears to provide more durable long-term results than the partial approach, as long as the technical elements of the operation are respected. Division of the SGVs, closure of the crura, and the use of mesh for large hiatal defects positively impacts long-term outcome. Hiatal hernia, atypical symptoms, poor antacid response, body mass index (BMI), and postoperative vomiting are potential predictors of failure in LARS.

Erosion of a Composite PTFE/ePTFE Mesh After Hiatal Hernia Repair

Primary repair of large hiatal defects is associated with higher than acceptable recurrence rates. This has led to the increased use of fascial prostheses for reinforcement of the hiatal repair. We report a case of intraluminal mesh erosion after repair of a recurrent paraesophageal hernia with a composite polytetrafluoroethylene/expanded polytetrafluoroethylene prosthesis in an 80-year-old woman. Mesh erosion is a rarely reported complication after hiatal hernia repair, and because many cases will go unreported, their true incidence is unknown. Besides the durability of mesh repair, the ongoing clinical trials investigating laparoscopic correction of hiatal hernias should also focus on the risk of complications associated with the use of prosthetic materials and the mode of fixation.
