Laparoscopic repair of large hiatal hernia with teres ligament: midterm follow-up

Background Although laparoscopic repair of large, mostly paraesophageal hiatal hernias is widely applied, there is a great concern regarding the higher recurrence rate associated with this procedure. In order to reduce this high recurrence rate, several techniques have been developed, mostly applying a mesh prosthesis for hiatal reinforcement. Methods We have recently introduced a new laparoscopic technique in which the hiatal closure is reinforced with the teres ligament. To date 26 patients have been entered into this ongoing prospective study. After the operation patients were called back on a regular basis for symptom evaluation and barium swallow. All 26 patients agreed to undergo barium swallow, with a mean follow-up of 35 months. Results The mean operative time was 115 min. Perioperative morbidity was 11.5%, and conversion to an open procedure was performed in six cases. No mortality was registered. Anatomic recurrence, investigated by barium swallows was observed in four patients (15.3%). Of those four, only one (3.85%) had a symptomatic recurrent paraesophageal hernia; the other three had asymptomtic sliding hernias. In three of the four patients with anatomic recurrence, the diameter of the hiatal hernia was greater than 9 cm at the original operation, and the fourth patient underwent reoperation for recurrent hiatal hernia. No symptomatic recurrence was found in patients with diameter of hiatal hernia between 6 and 9 cm. Conclusions Laparoscopic reinforcement of the hiatal closure with the ligamentum teres is safe and effective treatment for large hiatal hernias. However, it appears that patients with extremely large hiatal hernias are at greater risk of recurrence, and therefore large hernias are not suitable for this new technique.     

Laparoscopic repair of large paraesophageal hiatal hernia

BACKGROUND: The objective of this study was to analyze our initial results after laparoscopic repair of large paraesophageal hiatal hernias. METHODS: Between October 1997 and May 2000, 37 patients (23 women, 14 men) underwent laparoscopic repair of a large type II (pure paraesophageal) or type III (combined sliding and paraesophageal) hiatal hernia with more than 50% of the stomach herniated into the chest. Median age was 72 years (range 52 to 92 years). Data related to patient demographics, esophageal function, operative techniques, postoperative symptomatology, and complications were analyzed. RESULTS: Laparoscopic hernia repair and Nissen fundoplication was possible in 35 of 37 patients (95.0%). Median hospitalization was 4 days (range 2 to 20 days). Intraoperative complications occurred in 6 patients (16.2%) and included pneumothorax in 3 patients, splenic injury in 2, and crural tear in 1. Early postoperative complications occurred in 5 patients (13.5%) and included esophageal leak in 2, severe bloating in 2, and a small bowel obstruction in 1. Two patients died within 30 days (5.4%), 1 from delayed splenic bleeding and 1 from adult respiratory distress syndrome secondary to a recurrent strangulated hiatal hernia. Follow-up was complete in 31 patients (94.0%) and ranged from 3 to 34 months (median 15 months). Twenty-seven patients (87.1%) were improved. Four patients (12.9%) required early postoperative dilatation. Recurrent paraesophageal hiatal hernia occurred in 4 patients (12.9%). Functional results were classified as excellent in 17 patients (54.9%), good in 9 (29.0%), fair in 1 (3.2%), and poor in 4 (12.9%). CONCLUSIONS: Laparoscopic repair of large paraesophageal hiatal hernias is a challenging operation associated with significant morbidity and mortality. More experience, longer follow-up, and further refinement of the operative technique is indicated before it can be recommended as the standard approach.     

Prosthetic mesh repair of large and recurrent diaphragmatic hernias

Background Laparoscopic repair of large paraesophageal hernias (PEH) is associated with significant recurrence rates. Use of prosthetic mesh to complete tension-free repair of the hiatus has been suggested to decrease the recurrence rate. Methods Fifty-nine patients with large (n = 44) or recurrent (n = 15) PEH were operated on via the laparoscopic approach with the use of prosthetic mesh. Patients were followed with office visits and phone interviews. All patients were referred for barium studies. Data analysis included all patients, including conversions, on an intention-to-treat basis. Results Followup was completed in 56 (95%) patients. Mean followup time was 28.4 months. Forty patients (74%) had significant relief of all symptoms. Barium studies were performed in 45 patients (80.3%), including all symptomatic patients. Fifteen patients (33%) had a small sliding hernia, six (13.3%) had recurrent PEH, and four (8.8%) had narrowing of the gastroesophageal junction. Most patients with small hiatal hernias were symptomatic (60%). All responded to medical treatment. Conclusions Laparoscopic repair of large PEH with reinforcement mesh is feasible and safe with excellent short-term results. Long-term followup shows a low PEH recurrence requiring reoperation, but a significant number of patients develop symptomatic recurrent small hiatal hernias that can be managed nonoperatively.

Simultaneous laparoscopic paraesophageal hernia repair and sleeve gastrectomy in the morbidly obese

BackgroundMorbid obesity is associated with increased rates of hiatal and paraesophageal hernias. Although laparoscopic sleeve gastrectomy is gaining popularity as the procedure of choice for morbid obesity, there is little data regarding the management of paraesophageal hernias found intraoperatively. The aim of this study was to evaluate the feasibility and benefits of a combined sleeve gastrectomy and paraesophageal hernia repair in morbidly obese patients.MethodsFrom May 2011 to February 2013, 23 patients underwent laparoscopic sleeve gastrectomy combined with the repair of a paraesophageal hernia. Only 4 patients had a large hiatal hernia documented preoperatively on esophagogastroduodenoscopy (EGD). The body mass index (BMI), operative time, length of stay, and complications were evaluated.ResultsThe average operative time was 165 minutes (115–240 minutes) and length of stay was 2.83 days (2–6 days). All patients were female except for one, with an average age of 53.4 years and a BMI of 41.9 kg/m². There were no complications during the procedures. Mean follow-up was 6.16 months (1–19 months), and mean excess weight loss was 39%. The average cost of admission for a combined procedure ($10,056), was slightly higher than a laparoscopic sleeve gastrectomy ($8905) or laparoscopic paraesophageal hernia repair ($8954) done separately.ConclusionsLaparoscopic sleeve gastrectomy combined with a paraesophageal hernia repair is well-tolerated and feasible in morbidly obese patients. Surgeons should be aware that preoperative EGD is not effective at diagnosing large hiatal or paraesophageal hernias. Surgeons with the skill set to repair paraesophageal hernias should do a combined procedure because it is well-tolerated, feasible, and can reduce the cost of multiple hospital admissions.     

Laparoscopic repair of incarcerated paraesophageal hernias

Paraesophageal hernias comprise only 2–5% of all hiatal hernias, yet unlike the more common sliding hiatal hernia, paraesophageal hernias are prone to undergo volvulus, with obstruction, ischemia, and gangrenous perforation. Due to their propensity toward calamitous complications, they must be recognized and repaired as expeditiously as possible. Traditionally these hernias have been repaired by either an open transabdominal or an open transthoracic approach. Laparoscopic repair with Nissen fundoplication has already been successfully applied to the repair of the more common sliding hiatal hernia. Described here is the laparoscopic repair of two paraesophageal hernias. The merit of an anti-reflux procedure as part of this repair is discussed.     

Laparoscopic Hiatal Hernia Repair with Falciform Ligament Buttress

Background

Using synthetic mesh to buttress the crural repair during laparoscopic hiatal hernia repair may be associated with dysphagia and esophageal erosions, while a biologic mesh is expensive and does not decrease long-term recurrence rates. This study documents outcomes of laparoscopic paraesophageal hernia repairs using the falciform ligament to reinforce the crural repair.

Methods

This is a prospective study of laparoscopic paraesophageal hernia repairs with a falciform ligament buttress. Preoperatively and at 6 and 12 months postoperatively, medications, radiologic studies, and symptom severity and frequency scores were recorded. Patients with a hiatal defect greater than 5 cm were included, while patients with recurrent hiatal hernia repairs or prior gastric surgery were excluded. Symptom scores were compared pre- and postoperatively with a p?<?0.05 considered significant.

Results

One hundred four patients were included with a mean age of 62.4 years, and 57 patients underwent an upper gastrointestinal series at least 12 months from the initial operation with a mean follow-up of 20.6 months. The mean symptom severity score decreased from 14.32?±?0.93 to 4.75?±?0.97 (p?<?0.001), mean symptom frequency score decreased from 14.99?±?0.97 to 5.25?±?0.99 (p?<?0.001), and mean total symptom score decreased from 29.31?±?1.88 to 10.00?±?1.95 (p?<?0.001). Five patients developed recurrent hiatal hernias on upper gastrointestinal series, but only three required operative intervention.

Conclusions

Laparoscopic paraesophageal hernia repair with a falciform ligament buttress is a viable option for a durable closure. Ongoing follow-up will continue to illuminate the value of this approach to decrease morbidity and recurrence rates for hiatal hernia repair.

     

Laparoscopic management of giant paraesophageal herniation

BACKGROUND: Many surgeons have found laparoscopic fundoplication effective management of medically recalcitrant gastroesophageal reflux disease (GERD) associated with sliding type I hiatal hernias. The anatomic distortion and technical difficulty inherent with repair has limited the use of laparoscopy for repair of "giant" paraesophageal hernias (gPH). METHODS: Since July 1993, we have accomplished laparoscopic repair of paraesophageal hiatal hernias in 54 of 60 (90%) patients. Five patients had classic type II hernias with total intrathoracic stomachs, and 53 patients had large sliding/paraesophageal type III herniation. Two patients had true parahiatal hernias. None had gastric incarceration. Median age was 53 years and 28 of 60 (47%) were women. Chest pain and dysphagia were primary complaints from 39 of 60 (65%). Heartburn with or without regurgitation was present in 52 of 60 (85%). Preoperative manometry and prolonged pH testing were obtained on 43 of 60 (72%) and 44 of 60 (73%) patients, respectively. Principles of repair included reduction of the hernia, excision of the sac, crural approximation, and fundoplication over a 54F bougie (Nissen, 41; Dor, 1; Toupet, 18) to "pexy" the stomach within the abdomen and to control postoperative reflux. RESULTS: Mean operative time was 202+/-81 minutes. Conversion to "open" repair was required in 6 patients (iatrogenic esophageal injury in 2 patients and difficult hernia sac dissection in 4 patients). One postoperative mortality occurred as a result of sepsis and multiorgan failure after an intraoperative esophageal perforation. Follow-up barium swallow performed in 44 of 60 patients demonstrated recurrent hiatal hernias in 3 patients. Preoperative symptoms have been relieved in all but 3 patients. Reoperation for recurrent paraesophageal herniation has been required in these latter 3 patients. CONCLUSIONS: Although technically challenging, laparoscopic repair of paraesophageal hiatal hernias is a viable alternative to "open" surgical approaches. Control of the herniation and the patient's symptoms are equivalent and hospitalization and return to full activity are shorter.     

Laparoscopic mesh-augmented hiatoplasty without fundoplication as a method to treat large hiatal hernias

Purpose

Laparoscopic hiatal hernia repair with additional fundoplication is a commonly recommended standard surgical treatment for symptomatic large hiatal hernias with paraesophageal involvement (PEH). However, due to the risk of persistent side effects, this method remains controversial. Laparoscopic mesh-augmented hiatoplasty without fundoplication (LMAH), which combines hiatal repair and mesh reinforcement, might therefore be an alternative.

Methods

In this retrospective study of 55 (25 male, 30 female) consecutive PEH patients, the perioperative course and symptomatic outcomes were analyzed after a mean follow-up of 72 months.

Results

The mean DeMeester symptom score decreased from 5.1 to 1.8 (P < 0.001) and the gas bloating value decreased from 1.2 to 0.5 (P = 0.001). The dysphagia value was 0.7 before surgery and 0.6 (P = 0.379) after surgery. The majority of the patients were able to belch and vomit (96 and 92 %, respectively). Acid-suppressive therapy on a regular basis was discontinued in 68 % of patients. In 4 % of patients, reoperation was necessary due to recurrent or persistent reflux. A mesh-related stenosis that required endoscopic dilatation occurred in 2 % of patients.

Conclusions

LMAH is feasible, safe and provides an anti-reflux effect, even without fundoplication. As operation-related side effects seem to be rare, LMAH is a potential treatment option for large hiatal hernias with paraesophageal involvement.     

Clinical and radiologic assessment of laparoscopic paraesophageal hernia repair

Background: Unlike sliding hiatal hernias, paraesophageal hiatal hernias (PEH) present a risk of catastrophic complications and should be repaired. To assess laparoscopic repair of PEH, we prospectively evaluated the outcome of 38 consecutive patients with type II (20 patients) or III (18 patients) PEH treated laparoscopically. Methods: With the use of 5 or 6 ports, laparoscopic PEH reduction and repair was attempted. One patient (3%) was converted to an open procedure. In the first 12 patients, the hiatus was closed using varying techniques including the placement of prothestic mesh in 6 patients, and the hernia sac was not routinely excised. In the next 25 patients, the hernia sac always was excised and the hiatus routinely sutured posteriorly to the esophagus. Twenty-nine patients also underwent either a Nissen (n= 27) or Toupet (n= 2) fundoplication, which is now performed routinely. Sutured anterior gastropexy was performed selectively in 10 of the first 20 patients, then routinely, using T-fasteners in the last 17 patients. Barium swallow studies were performed on all patients at 3 to 5 months postoperatively. Results: Mean ± standard error of the mean (SEM) age was 67 ± 2 year (range, 39–92 years; 11 men, 27 women), and the American Society of Anesthesia (ASA) score was 2.5 ± 0.1. The operating time was 195 ± 10 min: 244 ± 15 min in the first 12 patients and 170 ± 11 min in the last 25 patients (p < 0.001). There were three (8%) intraoperation complications, which were treated without sequelae, and four (11%) grade II postoperation morbidities. Median discharge was 3 days, and return to full activity was 14 days. Two patients (5%) died of cardiovascular disease after discharge. Barium swallow revealed 2/35 (6%) PEH recurrences (1 reoperated), 3 (9%) intrathoracic wraps, and 3 (9%) small sliding hiatal hernias. At follow-up of 1 year or more, 6/28 (21%) patients noted mild symptoms of reflux or bloating, but only 1 patient (4%) required medication for these symptoms. Conclusions: Laparoscopic PEH repair offers a reasonable alternative to traditional surgery, especially for high-risk patients. Rapid recovery is achieved with acceptable morbidity and early outcome. Barium x-rays revealed hiatal abnormalities in a significant fraction of patients, many of whom were asymptomatic. Longer follow-up will be required to determine the ideal strategy for management of these patients. Received: 4 April 1998/Accepted: 9 December 1998     

Laparoscopic Repair of Paraesophageal Hernias

Background and Objectives:

Laparoscopy has quickly become the standard surgical approach to repair paraesophageal hernias. Although many centers routinely perform this procedure, relatively high recurrence rates have led many surgeons to question this approach. We sought to evaluate outcomes in our cohort of patients with an emphasis on recurrence rates and symptom improvement and their correlation with true radiologic recurrence seen on contrast imaging.

Methods:

We retrospectively identified 126 consecutive patients who underwent laparoscopic repair of a large paraesophageal hernia between 2000 and 2010. Clinical outcomes were reviewed, and data were collected regarding operative details, perioperative and postoperative complications, symptoms, and follow-up imaging. Radiologic evidence of any size hiatal hernia was considered to indicate a recurrence.

Results:

There were 95 female and 31 male patients with a mean age (± standard deviation) of 71 ± 14 years. Laparoscopic repair was completed successfully in 120 of 126 patients, with 6 operations converted to open procedures. Crural reinforcement with mesh was performed in 79% of patients, and 11% underwent a Collis gastroplasty. Fundoplications were performed in 90% of patients: Nissen (112), Dor (1), and Toupet (1). Radiographic surveillance, obtained at a mean time interval of 23 months postoperatively, was available in 89 of 126 patients (71%). Radiographic evidence of a recurrence was present in 19 patients (21%). Reoperation was necessary in 6 patients (5%): 5 for symptomatic recurrence (4%) and 1 for dysphagia (1%). The median length of stay was 4 days.

Conclusion:

Laparoscopic paraesophageal hernia repair results in an excellent outcome with a short length of stay when performed at an experienced center. Radiologic recurrence is observed relatively frequently with routine surveillance; however, many of these recurrences are small, and few patients require correction of the recurrence. Furthermore, these small recurrent hernias are often asymptomatic and do not seem to be associated with the same risk of severe complications developing as the initial paraesophageal hernia.     

The Impact of Scoliosis Among Patients with Giant Paraesophageal Hernia

Background

Kyphoscoliosis is seen in approximately 1.4?C15% of the octogenarian population of the US. We hypothesized that patients with kyphoscoliosis are affected with a reduced intra-abdominal volume and progressive laxity of the diaphragmatic hiatal sling musculature leading to an increased risk of hiatal hernia formation and progression over time.

Methods

We retrospectively reviewed the clinical history and roentgenographic data of 320 paraesophageal hernia patients from 2003 to 2007. The prevalence of kyphoscoliosis among this patient cohort and the outcomes of surgical management were compared to paraesophageal hernia patients without kyphoscoliosis.

Results

Ninety-three of the 320 patients (29.1%) were found to have significant K/S (mean age 74; 83% female). Laparoscopic repair of paraesophageal hernia with fundoplication was performed in 91% of these patients. There was one death (1.1%; aspiration pneumonia) and 17.2% major postoperative morbidity. Mean length of hospital stay was 8 days (median?=?4; range 2?C71). Prolonged stays were related mainly to marginal pulmonary status. Kyphoscoliosis was associated with increased peri-operative pulmonary morbidity (16.1%) compared to patients without kyphoscoliosis (7.0%, p?=?0.02).

Conclusion

Kyphoscoliosis may contribute to the development and progression of paraesophageal hernias. Surgeons approaching paraesophageal hernia repair should be aware of the increased pulmonary morbidity and the postoperative care required in managing these patients.     

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     

The use of small intestine submucosa in the repair of paraesophageal hernias: initial observations of a new technique

BACKGROUND: Recent reports suggest that when laparoscopy is used to repair paraesophageal hernias recurrence rates reach 20% to 40%. Tension-free hernia closure with synthetic mesh reduces recurrence but occasionally results in esophageal injury. We hypothesized that reinforcement of the hiatal closure with small intestine submucosa (SIS) mesh, in some unusually large hernias, might reduce recurrence rates without causing injury to the esophagus. METHODS: From January 2001 to March 2002 we treated 18 large paraesophageal hernias via a laparoscopic approach. In 9 of the largest hernias (one type II and 8 type III, of which 1 was recurrent) the repair was reinforced with SIS mesh (Surgisis, Cook Surgical) and represent the subjects of this study. Nissen fundoplication with gastropexy was performed in all patients. Clinical follow-up ranged from 3 to 16 months (median 8). Every patient was evaluated with barium esophagram or endoscopy or both 1 to 8 months (median 2) postoperatively. RESULTS: The presenting symptoms were postprandial pain/fullness (9 of 9), heartburn (4 of 9), anemia (4 of 9), dysphagia (3 of 9), regurgitation (3 of 9), and chest pain (3 of 9). One patient died of a hemorrhagic stroke within 30 days of the operation. Postoperatively, presenting symptoms resolved (83%) or improved (17%) in each of the remaining 8 patients. One patient required endoscopic dilation for mild dysphagia. Seven of 8 patients had a normal barium esophagram without evidence of hernia. One morbidly obese (body mass index = 47) patient had a small (2 cm) sliding hiatal hernia postoperatively. There were no other complications, and specifically no perforations or mesh erosions. CONCLUSIONS: These observations suggest that the use of SIS in the repair of paraesophageal hernias is safe and may reduce recurrence. Longer follow-up and a randomized study are needed to validate these results.     

Treatment of giant hiatal hernia by laparoscopic Roux-en-Y gastric bypass

IntroductionObesity is a risk factor for hiatal hernia. In addition, much higher recurrence rates are reported after standard surgical treatment of hiatal hernia in morbidly obese patients. Laparoscopic Roux-en-Y gastric bypass (LRYGB) is an effective surgical treatment for morbid obesity and is known to effectively control symptoms of gastroesophageal reflux (GERD).Case presentationTwo patients suffering from giant hiatal hernias where a combined LRYGB and hiatal hernia repair (HHR) with mesh was performed are presented in this paper. There were no postoperative complications and at 1 year follow-up, there was no sign of recurrence of the hernia.DiscussionThe gold standard for all symptomatic reflux patients is still surgical correction of the paraesophageal hernia, including complete reduction of the hernia sac, resection of the sac, hiatal closure and fundoplication. However, HHR outcome is adversely affected by higher BMI levels, leading to increased HH recurrence rates in the obese.ConclusionConcomitant giant hiatal hernia repair with LRYGB appears to be safe and feasible. Moreover, LRYGB plus HHR appears to be a good alternative for HH patients suffering from morbid obesity as well than antireflux surgery alone because of the additional benefit of significant weight loss and improvement of obesity related co-morbidity.     

Allograft dermal matrix hiatoplasty during laparoscopic primary fundoplication, paraesophageal hernia repair, and reoperation for failed hiatal hernia repair

Background

Hiatal repair failure is the nemesis of laparoscopic paraesophageal hernia repair as well as the major cause of failure of primary fundoplication and reoperation on the hiatus. Biologic prosthetics offer the promise of reinforcing the repair without risks associated with permanent prosthetics.

Design

Retrospective evaluation of safety and relative efficacy of laparoscopic hiatal hernia repair using an allograft (acellular dermal matrix) onlay. Patients with symptomatic failures underwent endoscopic or radiographic assessment of hiatal status.

Results

Greater than 6-month follow-up was available for 252 of 450 consecutive patients undergoing laparoscopic allograft-reinforced hiatal hernia repair between January 2007 and March 2011. No erosions, strictures, or persisting dysphagia were encountered. Adhesions were minimal in cases where reoperation was required. Failure of the hiatal repair at median 18 months (6–51 months) was significantly (p < 0.005) different between groups: group A (primary fundoplication with axial hernia ≤ 2 cm), 3.7 %; group B (primary fundoplication with axial hernia 2–5 cm), 7.1 %; group G (giant/paraesophageal), 8.8 %; group R (reoperative), 23.4 %. Additionally, mean time to failure was significantly shorter in group R (247 days) compared with the other groups (462–489 days).

Conclusions

Use of allograft reinforcement to the hiatus is safe at 18 months median follow-up. Reoperations had a significantly higher failure rate and shorter time to failure than the other groups despite allograft, suggesting that primary repairs require utmost attention and that additional techniques may be needed in reoperations. Patients with hiatal hernias >2 cm axially had a recurrence rate equal to that of patients undergoing paraesophageal hiatal hernia repair, and should be treated similarly.     

Importance of dissection of the hernial sac in laparoscopic surgery for large hiatal hernias.

HYPOTHESIS: Laparoscopic repair of large hiatal hernia is an appropriate management strategy. DESIGN: A prospective patient series. SETTING: A university teaching hospital. PATIENTS: All patients with hiatal hernias 10 cm or greater in diameter repaired laparoscopically between February 1, 1992, and September 30, 1998. INTERVENTIONS: Two operative strategies were used for laparoscopic repair: the first, which was used until early 1996, entailed initial esophageal dissection while leaving the sac in the mediastinum. The second involved preliminary dissection of the hernial sac from the mediastinum before dissecting the esophagus. MAIN OUTCOME MEASURES: Successful completion of the procedure using a laparoscopic technique, postoperative complication rate, reoperation rate, and clinical outcome. RESULTS: Eighty-six patients with a large hiatal hernia underwent attempted repair using laparoscopic methods. The median age was 63 years (range, 30-91 years), and 45 patients (52%) were women. There were 30 sliding, 10 rolling, and 46 mixed hiatal hernias. Operating times ranged from 48 to 240 minutes (median, 90 minutes), and 20 procedures (23%) were converted to an open operation. Conversion was significantly more common in the first half of our experience (16 [40%] of 40 patients vs 4 [9%] of 46 patients) before the operative strategy was changed. Esophageal-lengthening procedures were not carried out for any patient. At follow-up of a median of 2 years, 1 patient has moderate dysphagia, 4 patients have reflux symptoms, and 1 patient has undergone further surgery for a recurrent paraesophageal hernia. An overall satisfactory outcome was achieved in 81 patients (94%). CONCLUSIONS: Large hiatal hernias can be treated effectively laparoscopically. Dissecting the sac fully from the mediastinum before dissecting the esophagus helps to safely mobilize the esophagus, and we think changing to this strategy is the main reason for the improved laparoscopic success rate reported in the latter half of this series.     

Laparoscopic paraesophageal hernia repair with acellular dermal matrix cruroplasty

Background:

Laparoscopic paraesophageal hernia repair (LPEHR) has been shown to be both safe and efficacious. Compulsory operative steps include reduction of the stomach from the mediastinum, resection of the mediastinal hernia sac, ensuring an appropriate intraabdominal esophageal length, and crural closure. The use of mesh materials in the repair of hiatal hernias remains controversial. Synthetic mesh may reduce hernia recurrences, but may increase postoperative dysphagia and result in esophageal erosion. Human acellular dermal matrix (HADM) may reduce the incidence of hernia recurrence with reduced complications compared with synthetic mesh.

Methods:

A retrospective review of all cases of laparoscopic hiatal hernia repair using HADM from December 2008 through March 2010 at a single institution was performed evaluating demographic information, BMI, operative times, length of stay, and complications.

Discussion:

Forty-six LPEHRs with HADM were identified. The mean age of patients was 60.3 years (±13.9); BMI 30.3 (±5.3); operative time 182 minutes (±56); and length of stay 2.6 days (±1.9). Nine of 46 (19.6%) patients experienced perioperative complications, including subcutaneous emphysema without pneumothorax (n=2), urinary retention (n=1), COPD exacerbation (n=2), early dysphagia resolving before discharge (n=1), esophageal perforation (n=1), delayed gastric perforation occurring 30 days postoperatively associated with gas bloat syndrome (n=1), and PEG site abscess (n=1). There were 2 clinically recurrent hernias (4.3%). Radiographic recurrences occurred in 2 of 26 patients (7.7%). Six of 46 (13%) patients reported persistent dysphagia.

Conclusion:

LPEHR with HADM crural reinforcement is an effective method of repairing symptomatic paraesophageal hernias with low perioperative morbidity. Recurrences occur infrequently with this technique. No mesh-related complications were seen in this series.     

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 paraesophageal hiatal hernias

The advent of minimally invasive techniques has brought about a shift in the operative approach of patients with paraesophageal hiatal hernia. Today, the laparoscopic repair of a paraesophageal hiatal hernia has almost completely replaced the open approach through either a laparotomy or a left thoracotomy. The laparoscopic repair of paraesophageal hiatal hernias is a technically challenging operation; however, it is technically feasible and safe, and it is associated with a positive relief of symptoms, decreased postoperative pain, and a rapid return to normal activities (1, 2). This paper describes, step by step, our approach to the laparoscopic repair of a paraesophageal hiatal hernia.     

Laparoscopic paraesophageal hernia repair has an acceptable recurrence rate

Recent literature has reported as high as a 42 per cent recurrence rate after laparoscopic paraesophageal hernia repair (LPEHR). We report long-term follow-up in a cohort of patients undergoing LPEHR at Vanderbilt University. Thirty-one patients underwent attempted LPEHR between September 1993 and May 2000. Six of 31 patients (19%) were converted to an open procedure and were excluded from the study. All patients had complete excision of the sac, primary closure of the crura, and an antireflux procedure. An Institutional Review Board-approved follow-up barium esophagram was performed at a mean of 25 months postoperatively. Three experienced laparoscopic surgeons (K.S., M.H., and W.R.) collectively reviewed the esophagrams for evidence of recurrence. The mean age of patients was 61 years (range 41-92). There were six males and 19 females. Fifteen of 25 patients (60%) returned for an esophagram. Only one of 15 patients (7%) had a recurrent paraesophageal hernia. However, five of 15 patients (33%) had herniated an intact wrap 2 to 4 cm above the diaphragm. The patient with a true paraesophageal hernia recurrence returned with symptoms of dysphagia. Two of the five patients (40%) with a herniated wrap complained of heartburn, which was controlled with a proton pump inhibitor. All other patients were asymptomatic. Our recurrence rate of true paraesophageal hernias after LPEHR is low (7%) and compares with that reported in the literature for open repairs. However, 33 per cent of the patients in this study were found to have a herniated wrap. Because there is no risk of strangulation we have not operated on any of these patients. LPEHR is our procedure of choice for Type II and III hiatal hernias with good symptom relief and a low true recurrence rate.
