Paraesophageal hernia: surgery problems in emergency

CASE REPORT: It has been demonstrated that paraesophageal hiatal hernia surgical repair can be performed by endoscopic means, but the procedure is not standardized and results have not been evaluated systematically so far. The Authors report a case of strangulated paraesophageal hiatal hernia occurred in a elderly man and treated with open approach. Eighteen months later, follow up has demonstrated the effectiveness of the repair and the total remission of the symptoms. Recurrences after paraesophageal hiatal hernias repair may decrease with usage of mesh in the hiatus; however uniform criteria for this procedure are lacking. After review of the literature inheriting this uncommon pathology, that present about 5% of the hiatal hernias, no conclusions could be drawn regarding the reliability of the laparoscopic procedure and the necessity for an additional antireflux repair. Moreover, uniform specific indications for the need of an esophageal lengthening procedure or preoperative assessment methods for shortened esophagus cases could not be detected. CONCLUSIONS: Treatment based on standardized protocols for preoperative assessment and postoperative follow-up is required to clarify the current controversies inherent surgery indications and approach.     

Laparoscopic repair of a paraesophageal hiatus hernia without fundoplication

We treated a case of paraesophageal hiatus hernia by laparoscopic repair. The procedure included a reduction of the gastric fundus and duodenal bulbus, closure of the diaphragmatic defect, mesh wrapping of the closure, gastropexy to the diaphragm, and a gastrostomy. Preoperative monitoring of the pH for 24h showed no reflux. Intraoperative intraluminal manometry of the esophagus after hernia reduction showed the pressure of the lower esophageal sphincter to be normal, and thus an antireflux procedure was not deemed to be necessary. The patient was put on a soft diet from postoperative day 2. A postoperative upper gastrointestinal series showed no gastroesophageal reflux. No complications or recurrence of the hiatus hernia have been observed in the 12 months since the operation. Laparoscopic repair of a paraesophageal hiatus hernia with normal pressure of the lower esophageal sphincter, so that fundoplication is not needed, is thus considered to be possible.     

Fatal cardiac tamponade after emergency tension-free repair of a large paraesophageal hernia

Paraesophageal hernia is an unusual disorder of the esophageal hiatus that may be associated with life-threatening mechanical problems. We report a case of a large paraesophageal hernia that presented with acute thoracic herniation and incarceration of the stomach. The patient underwent laparoscopic operation, including reduction of an intrathoracic stomach, hernial sac removal, and tension-free repair of the hiatus with polytetrafluoroethylene (PTFE) mesh. The mesh was fixed with a straight hernia stapler. Postoperatively the patient developed a fatal cardiac tamponade secondary to a coronary vein laceration due to fixation of the mesh with the stapler. Different operative techniques and possibilities for prevention of the complication are discussed.     

Laparoscopic paraesophageal hernia repair

The term paraesophageal hernia is described as a herniation of the gastric fundus through the open hiatus into the thoracic cavity while the lower esophageal sphincter (LES) remains in its normal anatomic position. This is considered a rolling esophageal hernia (Type II), and it is the least commonly encountered hiatal hernia. A more commonly encountered herniation of the fundus of the stomach is the Type III hernia, in which both the LES and the fundus herniate into the chest. This has also been classified as a paraesophageal hernia. The most common hiatal hernia is a sliding hiatal hernia (Type I), which consists of herniation of the stomach through the esophageal hiatus, causing the LES and gastric cardia to lie in the thoracic cavity. There are several controversial issues involved in paraesophageal hernia repair, including indications for surgery, the most appropriate surgical approach, and the need for a concomitant antireflux procedure. The increasing popularity of laparoscopic paraesophageal hernia repair has dramatically altered the approach to these patients and has allowed patients at higher risk to better tolerate this procedure with a decrease in morbidity and mortality. However, they remain difficult surgical procedures.     

Laparoscopic Repair of a Giant Hiatus Hernia—How I Do It

The laparoscopic approach is now the technique of choice for the repair of large hiatus hernia. It is associated with a low risk of complications. However, controversy exists as to the optimal technique for laparoscopic repair. In this paper, we describe our approach. This entails full dissection of the hernia sac from the mediastinum, hiatal repair with posteriorly placed sutures, and then construction of an appropriate fundoplication. Whether the use of mesh for hiatal repair will reduce the risk of subsequent reintervention and not add any new risks is, however, unclear. For this reason, we believe that the mesh should only be used in appropriately designed clinical trials, and for now, the standard approach to laparoscopic repair of a large hiatus hernia is sutured repair.     

Prosthetic closure of the esophageal hiatus in large hiatal hernia repair and laparoscopic antireflux surgery

BACKGROUND: Laparoscopy has become the standard surgical approach to both surgery for gastroesophageal reflux disease and large/paraesophageal hiatal hernia repair with excellent long-term results and high patient satisfaction. However, several studies have shown that laparoscopic hiatal hernia repair is associated with high recurrence rates. Therefore, some authors recommend the use of prosthetic meshes for either laparoscopic large hiatal hernia repair or laparoscopic antireflux surgery. The aim of this article was to review available studies regarding the evolution, different techniques, results, and future perspectives concerning the use of prosthetic materials for closure of the esophageal hiatus. METHODS: A search of electronic databases, including Medline and Embase, was performed to identify available articles regarding prosthetic hiatal closure for large hiatal or paraesophageal hernia repair and/or laparoscopic antireflux surgery. Techniques and results as well as recurrence rates and complications related to the use of prosthetics for hiatal closure were reviewed and compared. Additionally, recent experiences and recommendations of experienced experts in this field were collected. RESULTS: The results of 42 studies were analyzed in this review. Some techniques of mesh hiatal closure were evaluated; however, most authors prefer posterior mesh cruroplasty. The type and shape of hiatal meshes vary from small angular meshes to A-shaped, V-shaped, or complete circular meshes. The most frequently utilized materials are polypropylene, polytetrafluoroethylene, or dual meshes. All studies show a low rate of postoperative hernia recurrence, with no mortality and low morbidity. In particular, comparative studies including two prospective randomized trials comparing simple sutured hiatal closure to prosthetic hiatal closure show a significantly lower rate of postoperative hiatal hernia recurrence and/or intrathoracic wrap migration in patients who underwent prosthetic hiatal closure. CONCLUSIONS: 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. The type of mesh, particularly the size and shape, is still controversial and is a matter for future research in this field.     

The influence of esophageal length on outcomes after laparoscopic fundoplication

BACKGROUND: It has been suggested that laparoscopic antireflux surgery has been associated with an increased incidence of postoperative paraesophageal hiatus herniation, and that this comes (at least in part) from not performing an esophageal lengthening procedure in patients with preoperative esophageal shortening. This study was undertaken to determine whether patients with esophageal shortening have an increased risk of reoperation after laparoscopic antireflux surgery. STUDY DESIGN: All patients who underwent a laparoscopic fundoplication between December 1991 and March 1999, and who had undergone preoperative esophageal manometry in our department were included in this study. Preoperative, operative, and followup data were collected prospectively, and original manometry recordings were reviewed to determine the length of the esophagus (the distance between the midpoints of the upper and lower esophageal sphincters). An index of esophageal length versus height was also calculated by dividing esophageal length by height. Esophageal length and the index were then compared with clinical outcomes. In addition, outcomes for the 50 patients with the shortest index was compared with outcomes of the 50 patients with the longest index. RESULTS: This study included 484 patients from an overall experience of 774 laparoscopic antireflux procedures. Postoperative followup ranged from 3 months to 5 years (median 2 years). Mean esophageal length was 23 cm (range 14 to 30 cm). There was a significant correlation between height and esophageal length (r = 0.44, p < 0.0001). Although patients with large hiatus hernias tended to have a shorter esophagus, preoperative endoscopic esophagitis grading did not influence length. Esophageal length did not influence the overall requirement for further surgical reintervention, although an analysis of esophageal length in patients who developed specific complications demonstrated that postoperative paraesophageal herniation was more likely in patients with a shorter esophagus, and reoperation for a tight esophageal hiatus was less likely in patients with a short esophagus. The incidence of paraesophageal hernia in the 50 patients with the shortest index was 8% versus 2% in the 50 patients with the longest index (p = 0.36). CONCLUSIONS: Although the overall reoperation rate after laparoscopic fundoplication was not influenced by esophageal length, this study did demonstrate an association between esophageal shortening and postoperative paraesophageal herniation. But the increased risk of this problem is small, and for this reason a case cannot be made for patients with a manometrically short esophagus to routinely undergo an esophageal lengthening procedure.     

Laparoscopic hiatal hernia repair in patients with poor esophageal motility or paraesophageal herniation

Laparoscopic repair for gastroesophageal reflux disease is now an accepted therapy. However, controversy exists with regard to the choice of operation between complete 360-degree Nissen fundoplication versus partial 270-degree Toupe fundoplication. In addition there is some controversy with regard to the proper choice of operation in patients with poor esophageal motility. Another class of hiatal hernia patients are those patients with paraesophageal herniation. Questions regarding the approach to these patients include whether or not to use a reflux procedure at the time of repair and the role of mesh in repair of these large hernias. This retrospective study was undertaken to compare the results of laparoscopic Nissen fundoplication and Toupe fundoplication in patients with both normal and abnormal esophageal motility. In addition the subset of patients with paraesophageal herniation was studied in an effort to ascertain the best surgical approach in these patients. In this study a retrospective analysis was performed on 188 consecutive patients during the period 1995 to 2001. All patients who presented with hiatal hernia surgical problems during this period were included. Endoscopy was performed in all patients with esophageal reflux. Manometry was performed in all patients except those presenting as emergency incarcerations. pH probe testing was performed in those patients in whom it was deemed necessary to establish the diagnosis. Upper gastrointestinal radiographs were used to define anatomy in paraesophageal hernia patients when possible. All patients with esophageal reflux were first treated with a trial of medical therapy. Patients with esophageal reflux and normal esophageal motility underwent 360-degree Nissen fundoplication. Those patients with poor esophageal motility (less than 65 mm of mercury) underwent laparoscopic 270-degree Toupe fundoplication. Patients presenting with paraesophageal herniation underwent laparoscopic repair. When possible esophageal manometry was performed on these patients preoperatively and if normal peristalsis was documented a Nissen fundoplication was performed. If poor esophageal motility was documented before surgery a Toupe fundoplication was performed. Mesh reinforcement of the diaphragmatic hiatus was used if necessary to complete a repair without tension. Patients were followed both by their primary gastroenterologist and their surgeon. Follow-up studies including endoscopy, pH probe, and upper gastrointestinal series were used as necessary in the postoperative period to document any problems as they occurred. Of the 188 patients in the study 141 patients underwent Nissen fundoplication, 21 patients underwent Nissen fundoplication and repair of paraesophageal hernia, 15 underwent Toupe fundoplication, seven underwent Toupe and paraesophageal hernia repair, and four paraesophageal hernia repair alone. One hundred eighty-three patients underwent a laparoscopic operation. Five patients of the 188 underwent an initial open operation-two of these patients because of the size of their paraesophageal hernia. Three of these patients had reoperations of remote operations done years before at other institutions. Twenty-two patients with poor esophageal motility (11.7 %) were included in the study. Fifteen patients required Toupe fundoplication whereas seven patients required Toupe fundoplication and repair of paraesophageal hernias. Mesh repair of paraesophageal hernias was accomplished in ten patients. Patients undergoing Toupe fundoplication had a 13 per cent dysphagia rate less than 4 weeks postoperatively and a 0% dysphagia rate greater than four weeks postoperatively. Patients undergoing Nissen fundoplication had a 16 per cent dysphagia rate less than 4 weeks postoperatively, 2 per cent dysphagia rate greater than 4 weeks postoperatively and no dysphagia at 6 weeks postoperatively. Recurrent symptomatic reflux occurred in 1.4 per cent of Nissen fundoplications and 6.7 per cent of Toupe fundoplications. Of Nissen and paraesophageal repairs 14.2 per cent had reflux and 14.3 per cent of Toupe and paraesophageal repairs had recurrent symptomatic reflux. Overall, complication rate was low. Use of mesh to repair large paraesophageal hernias resulted in a recurrence rate of 0 per cent. There was no instance of infection or bowel fistulization related to the use of mesh. We conclude that laparoscopic Nissen fundoplication in patients with normal esophageal motility is associated with a low rate of dysphagia and a low rate of recurrent reflux. Toupe fundoplication when used in reflux patients with poor esophageal motility is associated with a low rate of dysphagia and an acceptable rate of recurrent reflux. Laparoscop     

Complications of laparoscopic paraesophageal hernia repair

The complications of laparoscopic paraesophageal hernia repair at two institutions were reviewed to determine the rate and type of complications. A total of 76 patients underwent laparoscopic paraesophageal hernia repair between December 1992 and April 1996. Seventy-one of them had fundoplication (6 required a Collis-Nissen procedure). Five patients underwent hernia reduction and gastropexy only. There was one conversion to laparotomy. Traumatic visceral injury occurred in eight patients (11%) (gastric lacerations in 3, esophageal lacerations in 2, and bougie dilator perforations in 3). All lacerations were repaired intraoperatively except for one that was not recognized until postoperative day 2. Vagus nerve injuries occurred in at least three patients. Three delayed perforations occurred in the postoperative period (4%) (2 gastric and 1 esophageal). Two patients had pulmonary complications, two had gastroparesis, and one had fever of unknown origin. Seven patients required reoperation for gastroparesis (n=2), dysphagia after mesh hiatal closure of the hiatus (n=1), or recurrent herniation (n=4). There were two deaths (3%): one from septic complications and one from myocardial infarction. Paraesophageal hernia repair took significantly longer (3.7 hours) than standard fundoplication (2.5 hours) in a concurrent series (P<0.05). Laparoscopic paraesophageal hernia repair is feasible but challenging. The overall complication rate, although significant, is lower than that for nonsurgically managed paraesophageal hernia.

Paraesophageal hernias: open, laparoscopic, or thoracic repair?

The only treatment currently available for paraesophageal hernia is surgery, which is effective in most cases if the principles of operative therapy are followed. These principles include reducing the stomach, resecting the hernia sac, effectively closing the hiatus, and achieving sufficient gastropexy. The authors believe that a laparoscopic approach to paraesophageal hernias is safe and effective, allowing excellent visualization of the hiatus and superior esophageal mobilization, with significantly less physiologic insult to the debilitated patients in this population. Two questions remain, hoever. First, is an antireflux procedure necessary? The authors believe it is, because of the high rate of postoperative reflux. Additionally, the procedure does not add significant time to the overall operation and provides an excellent anchoring mechanism. Second, is there a higher rate of recurrence with laparoscopic repair? This concern, introduced by Hashemi et al, has not been raised by other authors. The authors have had few recurrences but currently are studying all of their asymptomatic patients for confirmation. For now, the authors consider laparoscopic paraesophageal hernia repair with Nissen fundoplication the procedure of choice for this difficult problem.     

Laparoscopic tension-free repair of large paraesophageal hernias

The paraesophageal hernia is an unusual disorder of the esophageal hiatus that may be associated with life-threatening mechanical problems. Elective repair is recommended at the time the condition is diagnosed, and open surgery can be accomplished with a low incidence of complications. The option of performing these repairs through a laparoscopic approach may further reduce morbidity and recovery time associated with surgical intervention. The purpose of this report was to review available options for laparoscopic repair and to present our experience with a tension-free technique for large paraesophageal hernias. Three patients with large diaphragmatic defects had laparoscopic repairs using an expanded polytetrafluorethylene (PTFE) patch secured with intracorporeal suturing techniques. One of these patients also underwent laparoscopic Toupet fundoplication in conjunction with repair of the hernia. In the other two patients, the fundus was secured to the right diaphragmatic crus to reduce the potential for recurrence and minimize postoperative reflux symptoms. All patients underwent successful repair without perioperative complications and had excellent long-term results. Laparoscopic repair of paraesophageal hernias can be accomplished by a number of different reported techniques. The use of a tension-free repair with PTFE may be particularly suitable for large diaphragmatic defects. An antireflux operation may be added selectively depending on clinical circumstances.     

Early results of the use of acellular dermal allograft in type III paraesophageal hernia repair.

BACKGROUND: Type III paraesophageal hernias are diaphragmatic defects with the risk of serious complications. High recurrence rates associated with primary suture repair are significantly improved with the use of a tension-free repair with prosthetic mesh. However, mesh in the hiatus is associated with multiple complications. A bio-engineered material from donated human tissue offers an attractive alternative material for hernia repair. This report is on the first series of laparoscopic type III paraesophageal hernia repairs with acellular dermal allografts (Allo-Derm, Lifecell Corporation, Branchburg, NJ) in 11 patients with follow-up evaluation. METHODS: From August 2003 to June 2004, 11 patients underwent laparoscopic repair of type III paraesophageal hernias with acellular dermal allografts. Patients were evaluated postoperatively with a symptoms questionnaire and barium esophagram. RESULTS: All patients were available for follow-up; however, 2 refused a barium esophagram. Average length of hospital stay was 3 days. Follow-up evaluation was at a mean interval of 1 year. Postoperatively, 9 of 11 patients reported no symptoms. Barium esophagram revealed one recurrence in an asymptomatic patient. CONCLUSION: Type III paraesophageal hernia can be laparoscopically repaired successfully with acellular dermal allografts.     

Giant paraesophageal hernia repair: Technical pearls

The optimal operative management of giant paraesophageal hiatal hernias continues to evolve, with recent series reporting promising results with minimally invasive approaches. The laparoscopic repair of a giant paraesophageal hernia is one of the more challenging cases a minimally invasive surgeon may perform. Our technical approach to this procedure involves a consistent emphasis on several key operative points: circumferential sac dissection with maintenance of crural integrity; extensive mediastinal esophageal dissection; crural closure with pledgeted sutures; wedge Collis gastroplasty for shortened esophagus; 3-stitch fundoplication incorporating esophageal tissue with each bite; additional sutures securing the top of the fundoplication to the crura; and biologic mesh buttressing. We believe that diligence paid toward these key steps permits laparoscopic giant paraesophageal hiatal hernia repair to be performed with similar outcomes as the open approach while avoiding the morbidity of thoracotomy or laparotomy.

Surgical repair of type II paraesophageal hernia: our experience

Type II paraesophageal hiatal hernia is a rare entity that is rarely discussed in the literature. This report is intended to depict the clinical profile of the disease and to discuss several controversial issues involved in the repair, including indications for surgery, the most appropriate surgical approach, and the need for a concomitant antireflux procedure. This study retrospectively reviews the experience with 12 patients affected by paraesophageal hernia who underwent a surgical repair between 1973 and 2001. Ten were women and two were men, with a mean age of 56.8 years. Clinical features and diagnostic assessment, as well as operative findings, are presented. Nine patients underwent an elective operation, and three patients underwent an emergency procedure for hernia complications. A thoracic approach was used in one patient, whereas the remaining 11 patients underwent an abdominal repair; the hernia sac was resected, and the hiatus was reconstructed in all of the patients. No postoperative deaths occurred; complications occurred in one patient, and only one recurrence was observed. Type II paraesophageal hernia seems to be a rare primary diaphragmatic defect. Its surgical repair is mandatory, because paraesophageal hernia is a potentially life-threatening disease because of the risk of severe complications; an elective repair should be performed wherever possible, even in asymptomatic patients. The main problems of the management are the choice of the surgical approach and the usefulness of an associated antireflux procedure to the hiatoplasty; in our opinion, a fundoplication should be added to all repairs.     

Laparoscopic management of large hiatus hernia with mesh cruroplasty

Purpose  

Laparoscopy has become the standard surgical approach to surgery for gastrooesophageal reflux disease (GERD) and hiatal hernia repair with excellent long-term results and high patient satisfaction. However several studies have shown that hiatal hernia repair, especially large hiatus are associated with high recurrence rate. Mesh reinforcement has been proposed for repair of large hiatus hernia. The objective of this study was to evaluate the role of mesh cruroplasty in management of large hiatus hernia (> 5 cm).     

Controversies in paraesophageal hernia repair; a review of literature

Background The surgical repair of paraesophageal hiatal hernias (PHH) can be performed by endoscopic means, but the procedure is not standardized and results have not been evaluated systematically so far. The aim of this review article was to clarify controversial subjects on the surgical approach and technique, i.e., recurrence rate after conventional versus laparoscopic PHH treatment, results of mesh reinforcement of the cruroplasty, the necessity for additional antireflux surgery, and indications for an esophageal lengthening procedure. Methods An electronic Medline search was performed to identify all publications reporting on laparoscopic and conventional PHH surgery. The computer search was followed by additional hand searches in books, journals, and related articles. All types of publications were evaluated because of a lack of high-level evidence studies such as randomized controlled trials. Critical analysis followed for all articles describing a study population of >10 patients and those reporting postoperative outcome. Results A total of 32 publications were reviewed. Randomized controlled trials comparing laparoscopic and open techniques could not be identified. Nineteen of the publications described the results of retrospective series. Therefore, most of the studies retrieved were low in hierarchy of evidence (level II-c or lower). The overall median hospital time as published was 3 days for patients operated laparoscopically and 10 days in the conventional group. Postoperative complications, such as pneumonia, thrombosis, hemorrhage, and urinary and wound tract infections, appeared to be more frequent after conventional surgery. Follow-up was longer for conventional surgery (median 45 months versus 17.5 months after the laparoscopic technique). Recurrence rates reported were higher in patients operated conventionally (median 9.1% versus 7.0% for patients operated laparoscopically). Recurrences after PHH repair may decrease with usage of mesh in the hiatus, although uniform criteria for this procedure are lacking. No conclusions could be drawn regarding the necessity for an additional antireflux procedure. Furthermore, uniform specific indications for the need of an esophageal lengthening procedure or preoperative assessment methods for shortened esophagus could not be detected. Conclusion Treatment based on standardized protocols for preoperative assessment and postoperative follow-up is required to clarify the current controversies.     

Preoperative determinants of an esophageal lengtheningprocedure in laparoscopic antireflux surgery

BACKGROUND: In a minority of patients undergoing antireflux surgery, an esophageal lengthening procedure is required to reduce the gastroesophageal junction (GEJ) below the esophageal hiatus. We evaluated risk factors associated with an irreducible GEJ to identify clinical features that were predictive of the need for a Collis gastroplasty in patients undergoing laparoscopic antireflux surgery. METHODS: Patients who required a Collis gastroplasty during a laparoscopic antireflux procedure (defined as the inability to reduce the GEJ > 2.5 cm below the esophageal hiatus despite extensive mobilization of the mediastinal esophagus) were compared to a random sample of patients who did not have a Collis gastroplasty. Predictors of the need for an esophageal lengthening procedure were identified using logistic regression modeling. Risks were expressed as odds ratios (OR) and 95% confidence intervals (CI). RESULTS: Twenty patients who had a Collis gastroplasty were compared to 133 patients who had adequate esophageal length. The presence of a stricture (OR 3.0; 95% CI 1.0, 9.7), paraesophageal hernia (OR 3.5; 95% CI 1.3, 9.6), Barrett's esophagus (OR 3.7, 95% CI 1.3, 10.7), and re-do antireflux surgery (OR 6.4; 95% CI 2.0, 20.7) were associated with the need for gastroplasty. Patients with none of these factors were extremely unlikely to require a gastroplasty (OR 0.08; 95% CI 0.02, 0.34). CONCLUSION: Patients undergoing laparoscopic antireflux surgery who are at high risk of needing an esophageal lengthening procedure can be easily identified preoperatively using simple clinical characteristics.     

Transthoracic repair of an incarcerated diaphragmatic hernia using hexamethylene diisocyanate cross-linked porcine dermal collagen (Permacol)

It is the general surgeon who commonly repairs paraesophageal hernias nowadays, and they are repaired laparoscopically, making the performance of thoracotomy relatively rare. Whether to use prosthetic materials to repair the hiatus is still under debate, as is the question of which material to use, if any. We report a case of a 38-year-old man who had a large, incarcerated paraesophageal hernia. He had a past history of extensive abdominal surgery for exomphalos, which rendered any abdominal surgical approach a high-risk procedure. We therefore decided to proceed with thoracotomy and repair of the hiatus with hexamethylene diisocyanate (HMDI) cross-linked porcine dermal collagen. He made a good recovery with no complications.     

Tension-free repair of hiatal hernia during laparoscopic fundoplication: a ten-year experience

Background: The breakdown of a hiatal hernia repair can lead to clinical failure. The use of prosthetic material at the esophageal hiatus to strengthen the crural repair is relatively new and questions remain. This report examines the safety and efficacy of a tension-free crural repair with mesh.Patients and methods: Since 1993, 135 consecutive patients (19–86) [9 re-do] completed laparoscopic tension-free hiatal hernia repair prior to Nissen wrap. Esophageal hiatus was patched with a PTFE mesh (first 112 patients) or a PTFE/ePTFE composite (23 patients) secured across the defect with staples to each crura. 130 patients completed a phone questionnaire during 2003/2004 (mean f/u 64 months).Results: There have been no short-term nor long-term infections related to the PTFE mesh. Symptoms were resolved or improved and resolved with meds in 122/130 (94%). Early re-herniation occurred in one patient after vigorous exercise.Conclusions: Mesh repair/patch of the esophageal hiatus can be done without infection, with results similar to standard crural repair and consistent with surgical principles of non-tension.
