Reconstruction of the phreno-esophageal ligament (R-PEL) prevents the intrathoracic migration (ITM) after concomitant sleeve gastrectomy and hiatal hernia repair.

BACKGROUND: Laparoscopic Sleeve Gastrectomy (LSG) is the most attractive bariatric procedure, but the postoperative intrathoracic gastric migration (ITM) and "de novo" GERD are major concerns. The main objective of our study was to evaluate the efficiency of the concomitant HHR with or without partial reconstruction of phreno-esophageal ligament (R-PEL) to prevent ITM after LSG. The secondary objectives focused on procedure's metabolic and GERD-related outcomes. PATIENTS AND METHOD: Consecutive patients who underwent primary LSG and concomitant HHR were included in a single-center prospective study. According to the HHR surgical technique, two groups were analyzed and compared: Group A included patients receiving crura approximation only and Group B patients with R-PEL. The patients' evolution of co-morbidities, GERD symptoms, radiologic, and endoscopic details were prospectively analyzed. RESULTS: Two hundred seventy-three patients undergoing concurrent HHR and LSG were included in the study (Group A and B, 146 and 127 patients) The mean age and BMI were 42.6 ± 11.3 and 43.4 ± 6.8 kg/m2. The 12-month postoperative ITM was radiologically found in more than half of the patients in Group A, while in group B, the GEJ's position appeared normal in 91.3% of the patients, meaning that R-PEL reduced 7 times the rate of ITM. The percentage of no-improvement and "de novo" severe esophagitis (Los Angeles C) was 4 times higher in group A 3.4% vs. 0.8% with statistical significance, and correlated to ITM. The GERD symptoms were less frequent in Group B vs Group A, 21.3% vs 37%, with statistical significance. No Barrett's esophagus and no complication were recorded in any of the patients. CONCLUSION: Concurrent LSG and HHR by crura approximation only has a very high rate of ITM in the first postoperative year (over 50%). R-PEL is an innovative technique which proved to be very efficient in preventing the ITM after HHR.

Laparoscopic repair of very large hiatus hernia with sutures versus absorbable mesh versus nonabsorbable mesh: a randomized controlled trial.

OBJECTIVE: Determine whether absorbable or nonabsorbable mesh in repair of large hiatus hernias reduces the risk of recurrence, compared with suture repair. BACKGROUND: Repair of large hiatus hernia is associated with radiological recurrence rates of up to 30%, and to improve outcomes mesh repair has been recommended. Previous trials have shown less short-term recurrence with mesh, but adverse outcomes limit mesh use. METHODS: Multicentre prospective double blind randomized controlled trial of 3 methods of repair: sutures versus absorbable mesh versus nonabsorbable mesh. Primary outcome-hernia recurrence assessed by barium meal radiology and endoscopy at 6 months. Secondary outcomes-clinical symptom scores at 1, 3, 6, and 12 months. RESULTS: A total of 126 patients enrolled: 43 sutures, 41 absorbable mesh, and 42 nonabsorbable mesh. Among them, 96.0% were followed up to 12 months, with objective follow-up data in 92.9%. A recurrent hernia (any size) was identified in 23.1% after suture repair, 30.8% after absorbable mesh, and 12.8% after nonabsorbable mesh (P = 0.161). Clinical outcomes were similar, except less heartburn at 3 and 6 months and less bloating at 12 months with nonabsorbable mesh; more heartburn at 3 months, odynophagia at 1 month, nausea at 3 and 12 months, wheezing at 6 months; and inability to belch at 12 months after absorbable mesh. The magnitudes of the clinical differences were small. CONCLUSIONS: No significant differences were seen for recurrent hiatus hernia, and the clinical differences were unlikely to be clinically significant. Overall outcomes after sutured repair were similar to mesh repair.

Initial outcomes of laparoscopic paraesophageal hiatal hernia repair with mesh.

The use of mesh in laparoscopic paraesophageal hiatal hernia repair (LHR) may reduce the risk of late hernia recurrence. The aim of this study was to evaluate initial outcomes and recurrence rate of 92 patients who underwent LHR reinforced with a synthetic bioabsorbable mesh. Surgical approaches included LHR and Nissen fundoplication (n = 64), LHR without fundoplication (n = 10), reoperative LHR (n = 9), LHR with a bariatric operation (n = 6), and emergent LHR (n = 3). The mean length of hospital stay was 2 ± 3 days (range, 1 to 30 days). There were no conversions to open laparotomy and no intraoperative complications. One of 92 patients (1.1%) required intensive care unit stay. The 90-day mortality was zero. Minor complications occurred in 3.3 per cent, major complications in 2.2 per cent, and late complications in 5.5 per cent of patients. There were no perforations or early hernia recurrence. The 30-day reoperation rate was 1.1 per cent. For patients with available 1-year follow-up, the overall recurrence rate was 18.5 per cent with a mean follow-up of 30 months (range, 12 to 51 months). LHR repair with mesh is associated with low perioperative morbidity and no mortality. The use of bioabsorbable mesh appears to be safe with no early hiatal hernia recurrence or late mesh erosion. Longer follow-up is needed to determine the long-term rate of hernia recurrence associated with LHR with mesh.

Laparoscopic prosthetic hiatal reinforcement for large hiatal hernia repair.

BACKGROUND: 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. PATIENTS AND METHODS: 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. RESULTS: 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. CONCLUSION: The addition of mesh reinforcement to surgical repair of large hiatal defects is safe and beneficial in terms of quality of life.

Hiatal hernias: a review of the pathophysiologic theories and implication for research.

BACKGROUND: The pathophysiology of hiatal hernias is incompletely understood. This study systematically reviewed the literature of hiatal hernias to provide an evidence-based explanation of the pathogenetic theories and to identify any risk factors at the molecular and cellular levels. METHODS: A systematic search of the Medline and Pubmed databases on the pathophysiology of hiatal hernias was performed to identify English-language citations from the database inception to December 2010. RESULTS: Although few studies have examined the relationship of molecular and cellular changes of the diaphragm to the pathogenesis of hiatal hernias, there appear to be three dominant pathogenic theories: (1) increased intraabdominal pressure forces the gastroesophageal junction (GEJ) into the thorax; (2) esophageal shortening due to fibrosis or excessive vagal nerve stimulation displaces the GEJ into the thorax; and (3) GEJ migrates into the chest secondary to a widening of the diaphragmatic hiatus in response to congenital or acquired molecular and cellular changes, such as the abnormalities of collagen type 3 alpha 1. CONCLUSIONS: The pathogenesis of hiatal hernias at the molecular and cellular levels is poorly described. To date, no single theory has proved to be the definitive explanation for hiatal hernia formation, and its pathogenesis appears to be multifactorial.

Hiatal hernia repair with the use of biologic meshes: a literature review.

During the past few years, biologic meshes, primarily evolved for routine and complex cases of abdominal wall reconstruction, have been evaluated in clinical cases and experimental models. Although there is published experience on the use of small intestine submucosa and human cadaveric dermis in hiatal hernia repair with encouraging results, porcine dermal collagen (PDC) matrix has not been subject of study to date in this patient population. A systematic review of the literature was conducted, aiming at evaluating the biomechanical characteristics of cross-linked PDC in comparison to synthetic and biologic meshes. Evidence shows that cross-linked PDC is superior to synthetic meshes in terms of incorporation, adhesion formation, and mesh fibrosis; their biodynamic and biotechnical characteristics do not seem to be superior to other bioprosthetic materials according to current data. The clinical and experimental results of cross-linked PDC implants justify their pilot clinical evaluation in hiatal hernia patients.

Postoperative incidence of incarcerated hiatal hernia and its prevention after robotic transhiatal esophagectomy.

BACKGROUND: Transhiatal robot-assisted total esophagectomy (RE) has gained acceptance as a minimally invasive procedure with several clinical benefits. In this report, the authors describe their experience with the incidence of incarcerated hiatal hernia after RE. METHODS: Between March 2007 and July 2009, 36 patients underwent RE at the authors' institution. A retrospective chart review was performed, and data were abstracted including gender, age, weight at surgery, presenting symptoms, pathologic diagnosis, operative time, estimated blood loss, mortality, and postoperative complications. RESULTS: The study cohort consisted of 28 men and 8 women undergoing RE. Their average age was 65.4±10.5 years, and their mean body weight was 86.2±24.8 kg at surgery. A review of medical records indicated that 7 (19.4%) of the 36 patients had postoperative incarcerated hiatal hernias. Two of these patients had experienced two episodes of incarceration, which required reoperation. One patient died of complications related to hernia repair. Six (85.7%) of 7 patients had a preexisting diagnosis of hiatus hernia which was significantly higher in comparison to the incidence of this complication within the group of 29 patients without post-operative hernia incarcerations (11 of 29, 37.9%; Fisher's exact p=0.04). CONCLUSIONS: The results indicate that postoperative incarcerated hiatal hernia after RE is an infrequently reported, albeit serious, complication. A preexisting hiatal hernia may put patients at a higher risk of incarceration. According to the authors' experience, a primary closure and reinforcement with mesh sutured to the gastric wall is recommended as a preventive measure. Diligent follow-up evaluation with regular computed tomography (CT) scans investigating likelihoods for incarceration is advisable, especially for patients with preexisting hernias.

Repair of the giant hiatal hernia.

The repair of hiatal hernias, specifically giant hiatal hernias, is technically challenging and controversial. The approach to repair has shifted from thoracic to open abdominal to laparoscopic, which appears to be the current standard. High recurrence rates have been reported with laparoscopic procedures, but these are anatomic recurrences that are largely asymptomatic. Symptomatic recurrences with laparoscopic procedures appear to be similar to those seen with open abdominal procedures, but without the additional morbidity conferred by laparotomy. In the last decade, several studies have reported improved rates of recurrence using prosthetic meshes that have decreased even radiologic recurrence rates to below 5%. However, this has come at the price of rare but serious complications such as erosion and fibrosis. Mesh repair appears to be associated with a higher perioperative rate of dysphagia, which tends to resolve within the intervening months. Biologic meshes have been implemented in an attempt to obtain the buttressing effect of prosthetic meshes without the complications of erosion or infection. Early results have not proven biologic meshes to be as effective in reducing recurrence rates as prosthetic meshes, but there are currently no reports of erosion. Continued research is needed to elicit the optimal type of repair and mesh.

Laparoscopic Nissen fundoplication combined with posterior gastropexy in surgical treatment of GERD.

BACKGROUND: Laparoscopic Nissen fundoplication (LNF) has become established as the procedure of choice in the surgical management of the majority of patients suffering from gastroesophageal reflux disease (GERD). Postoperative paraesophageal herniation has an incidence range up to 7% in the immediate postoperative period. AIM: A prospective randomized trial was scheduled to study the role of posterior gastropexy, in combination with LNF, in prevention of paraesophageal herniation and improvement of postoperative results in surgical treatment of GERD. PATIENTS AND METHODS: Eighty-two patients with GERD were randomized to LNF combined with (group A, n = 40) or without (group B, n = 42) posterior gastropexy. Subjective evaluation using disease-specific and generic questionnaires and structured interviews, and objective evaluation by endoscopy, esophageal manometry, and 24-h pH monitoring, were performed before operation, at 2 and 12 months after surgery, and then every year. Crura approximation was performed by stitches if the diameter was less than 6 cm, or with a patch to reinforce the conventional crural closure or by tension-free technique to close the hiatus. Posterior gastropexy (group A) was performed with one stitch between the posterior wall of the wrap and the crura near the arcuate ligament. RESULTS: Sixteen patients of group A and 15 patients of group B with concomitant abdominal diseases had simultaneous procedures [cholecystectomy 25, vagotomy 2, ventral hernia repair 1, gastric polypectomy 1, gastric fundus diverticulectomy 1, gastrointestinal stromal tumor (GIST) wedge resection 1]. In mean follow-up of 48 +/- 26 months (range 7-94 months), one patient of group B presented with paraesophageal herniation in the first postoperative month (reoperation), while recurrent gastroesophageal reflux (Visick III or IV), successfully treated by medication, was noted in three patients of group B and in one patient of group A. Only mild dysphagia, during the first two postoperative months, was noted in nine patients of group A and eight patients of group B. Six patients of each group with Barrett's esophagus had endoscopic improvement after the second postoperative month. Visick score in groups A/B was I in 26/11 (P < 0.0001), II in 13/27 (P = 0.037), III in 1/2 (not significant, NS), and IV in 0/2. Generally, Visick score was I or II in 39/38 in groups A/B (97.5%/90.5%, NS) and III or IV in 1/4 (2.5%/9.5%, P < 0.0001). CONCLUSIONS: LNF combined with posterior gastropexy may prevent postoperative paraesophageal or sliding herniation in surgical treatment of GERD, providing better early and long-term postoperative results.

Laparoscopic total esophagogastric dissociation.

The total esophagogastric dissociation (Bianchi's procedure) is used to control the severe gastroesophageal reflux in patients after failure of the fundoplication techniques. The laparoscopic approach can be usefully performed in patients with impaired respiratory function. We report here 2 patients in whom the total esophagogastric dissociation has been entirely performed by laparoscopy. The laparoscopic examination of the proximal esojejunal anastomosis is made feasible using an intestinal clamp placed to avoid the esophageal retraction up into the posterior mediastinum. The principal complication after this surgery is the risk of internal hernia.

Laparoscopic revisional fundoplication with circular hiatal mesh prosthesis: the long-term results.

BACKGROUND: Failure of hiatal closure has proven to be the most frequent complication leading to revisional surgery after primary failed open or laparoscopic antireflux surgery. To prevent hiatal hernia recurrence some authors recommend the use of prosthetic meshes for reinforcement of the hiatal crura. The aim of the present prospective study was to evaluate the safety and effectiveness of a circular hiatal onlay mesh prosthesis applied during laparoscopic refundoplication after primary failed antireflux surgery with intrathoracic wrap migration. The follow-up period was 5 years. METHODS: A total of 33 patients underwent laparoscopic refundoplication for recurrent symptoms of gastroesophageal reflux disease after primary failed laparoscopic or open antireflux surgery. The underlying morphological complication for symptom recurrence in all patients was hiatal hernia recurrence with intrathoracic migration of the fundoplication. During revisional surgery, after breakdown of the former fundoplication, the esophageal hiatus was thoroughly revised and a circular polypropylene mesh was used to buttress the primarily simple sutured hiatal crura. Additionally, in all patients a refundoplication was performed. Recurrences, complications, functional data, esophagogastroduodenoscopy, and cinematographic X-ray results, as well as quality of life data, were evaluated for the 60-month follow-up period. RESULTS: All reoperations were successfully completed laparoscopically. Twenty-one patients underwent laparoscopic 360 degrees "floppy" Nissen refundoplication, and 12 patients underwent laparoscopic 270 degrees Toupet refundoplication. Hiatal closure was performed by placing a circular polypropylene sheet that had a 3-4 cm keyhole for the esophageal body. Of 24 patients who underwent redo-surgery before May 2000, no patient developed a recurrent hiatal hernia during the first 12 postoperative months. All 33 patients were re-evaluated and underwent complete diagnostic work-up over a follow-up period of 60 months postoperatively. During the long-term follow-up, a new recurrent hiatal hernia with intrathoracic wrap migration developed in 2 patients (6%). In both cases, slippage occurred anteriorly to the esophagus. Both patients were scheduled for repeat refundoplication. In all other patients no recurrence occurred for the complete follow-up period, and no mesh-related complications developed. CONCLUSIONS: Laparoscopic refundoplication for primary failed hiatal closure with the use of a circular mesh prosthesis is a safe and effective procedure to prevent hiatal hernia recurrence for short- and mid-term follow-up. However, for long-term follow-up, even with the placement of prosthetic mesh, re-recurrence occurs in some patients, leading to repeated surgery.

Can recurrent reflux disease after fundoplication be circumvented by adding a vagotomy?

Gastro-esophageal reflux disease (GORD) is caused by a weak lower esophageal sphincter. Open Nissen fundoplication has been the most common surgical treatment of GORD and hiatus hernia. This paper describes the symptomatic result and quantifies the endoscopic improvement achieved by open Nissen fundoplication alone and when combined with truncal vagotomy in a series of 21 cases and studies whether the added vagotomy confers any additional benefits. From the results, it was concluded that, compared with fundoplication alone, an additional vagotomy does seem to prevent recurrent reflux disease. Therefore, in the absence of any contraindication, it is strongly recommended to combine a vagotomy(and if necessary a drainage procedure) with a Nissen fundoplication for the surgical treatment of GORD and hiatus hernia.

Risk factors for aspiration pneumonia after percutaneous endoscopic gastrostomy.

BACKGROUND: Percutaneous endoscopic gastrostomy (PEG) is generally used for long-term enteral nutrition. Patients who require PEG placement are often very sick, and postoperative complications, especially aspiration pneumonia, can be fatal. OBJECTIVE: In this study we investigated the risk factors for aspiration pneumonia after PEG using a simple two-step swallowing provocation test (S-SPT), as reported in 1999 by Teramoto et al. METHODS: The study included 29 patients (10 men, 19 women; mean age 84.6 years) who underwent S-SPT before PEG. We evaluated the presence of reflux esophagitis (RE) and esophageal hiatal hernia (EHH) with PEG. According to the S-SPT results, a normal response to the 1st step S-SPT was given a score of 0, a normal response to the 2nd step S-SPT was given a score of 1, and an abnormal response to the 2nd step S-SPT was given a score of 3. In addition to S-SPT, the presence of RE was given a score of 3, the absence of RE was given a score of 0, the presence of EHH was given a score of 2, and the absence of EHH was given a score of 0. We evaluated the association between the presence of aspiration pneumonia, as an early and critical complication, up to 1 month after PEG and determined the total risk score (score of S-SPT+ score of RE+ score of EHH). RESULTS: The group with an abnormal response to the 2nd step S-SPT and the group with RE both exhibited aspiration pneumonia. The patients with aspiration pneumonia all achieved total scores > or =3, and 8 of 13 patients without aspiration pneumonia achieved scores < or =2. CONCLUSIONS: S-SPT is particularly useful in PEG patients. The scores provided by S-SPT and endoscopic examination can be very useful for aspiration pneumonia after PEG. The patients with scores < or =2 appear to be at very low risk for aspiration pneumonia, and patients with the scores > or =3 should be carefully followed up.

Biologic prosthesis reduces recurrence after laparoscopic paraesophageal hernia repair: a multicenter, prospective, randomized trial.

OBJECTIVE: Laparoscopic paraesophageal hernia repair (LPEHR) is associated with a high recurrence rate. Repair with synthetic mesh lowers recurrence but can cause dysphagia and visceral erosions. This trial was designed to study the value of a biologic prosthesis, small intestinal submucosa (SIS), in LPEHR. METHODS: Patients undergoing LPEHR (n = 108) at 4 institutions were randomized to primary repair -1 degrees (n = 57) or primary repair buttressed with SIS (n = 51) using a standardized technique. The primary outcome measure was evidence of recurrent hernia (> or =2 cm) on UGI, read by a study radiologist blinded to the randomization status, 6 months after operation. RESULTS: At 6 months, 99 (93%) patients completed clinical symptomatic follow-up and 95 (90%) patients had an UGI. The groups had similar clinical presentations (symptom profile, quality of life, type and size of hernia, esophageal length, and BMI). Operative times (SIS 202 minutes vs. 1 degrees 183 minutes, P = 0.15) and perioperative complications did not differ. There were no operations for recurrent hernia nor mesh-related complications. At 6 months, 4 patients (9%) developed a recurrent hernia >2 cm in the SIS group and 12 patients (24%) in the 1 degrees group (P = 0.04). Both groups experienced a significant reduction in all measured symptoms (heartburn, regurgitation, dysphagia, chest pain, early satiety, and postprandial pain) and improved QOL (SF-36) after operation. There was no difference between groups in either pre or postoperative symptom severity. Patients with a recurrent hernia had more chest pain (2.7 vs. 1.0, P = 0.03) and early satiety (2.8 vs. 1.3, P = 0.02) and worse physical functioning (63 vs. 72, P = 0.03 per SF-36). CONCLUSIONS: Adding a biologic prosthesis during LPEHR reduces the likelihood of recurrence at 6 months, without mesh-related complications or side effects.

Prevention of recurrence by reinforcement of hiatal closure using ligamentum teres in laparoscopic repair of large hiatal hernias.

UNLABELLED: BACKGROUND. Several attempts were made to develop an effective technique to reduce the high recurrence rate associated with the repair of large hiatal hernias. METHODS: A new laparoscopic technique was introduced to reinforce hiatal closure with the ligamentum teres. Its feasibility, safety, and efficacy were evaluated. Four patients with gastroesophageal reflux disease and large hiatal hernia (>6 cm) entered the study. After closure of the diaphragmatic crura the teres ligament was dissected, brought behind the esophagus, and sutured to the crura. A fundoplication was also added. Patients were followed with barium swallow at 3 months postoperatively. RESULTS: The mean operation time was 109.5 min. No intraoperative complications, perioperative morbidity, or mortality were registered. At the follow-up, barium swallows revealed no recurrence. CONCLUSION: On the basis of these preliminary results laparoscopic reinforcement of the hiatal closure with the ligamentum teres seems feasible and safe; therefore this promising technique should be considered as an option for the treatment of large hiatal hernias.

Anterior gastropexy may reduce the recurrence rate after laparoscopic paraesophageal hernia repair.

BACKGROUND: Although laparoscopic repair of type 3 paraesophageal hernias is safe and results in symptomatic relief, recent data have questioned the anatomic integrity of the laparoscopic approach. The reports document an asymptomatic recurrence rate as high as 42% with radiologic follow-up evaluation for type 3 paraesophageal hernias repaired laparoscopically. This disturbingly high recurrence rate has prompted the addition of an anterior gastropexy to our standard laparoscopic paraesophageal hernia repair. METHODS: A prospective series of 28 patients underwent laparoscopic repair of large type 3 hiatal hernias between July 2000 and January 2002 at the Cleveland Clinic Foundation by one surgeon. All the patients underwent reduction of the hernia, sac excision, crural repair, antireflux procedure, and anterior gastropexy. They all had a video esophagram 24 h after surgery, then at 3-, 6-, and 12-month follow-up visits and annually thereafter. Symptomatic outcomes were assessed with a standard questionnaire at each follow-up visit. RESULTS: In this study, 21 women and 7 men with a mean age of 67 years (range, 35-82 years) underwent successful laparoscopic paraesophageal hernia repair. The mean operative time was 146 min (range, 101-186 min), and the average blood loss was 71 ml (range, 10-200 ml). One intraoperative complication occurred: A small esophageal mucosal tear occurred during esophageal dissection and was repaired laparoscopically. At 24 h, upper gastrointestinal examination identified no leaks. At this writing, all the patients have undergone video esophagram at a 3-month follow-up visit. All were asymptomatic and all examinations were normal. Of the 28 patients, 27 have undergone follow-up assessment at 6 months. At this writing, all the patients have undergone video esophagram at 3, 6, and 12 months follow up visits. All were asymptomatic and all examinations were normal. Ten patients have completed 2 year follow up barium swallows with no recurrences. CONCLUSIONS: With up to 2 years of follow-up evaluation, the addition of an anterior gastropexy to the laparoscopic repair of type 3 hiatal hernias resulted in no recurrences. These encouraging results necessitate further follow-up evaluation to document the long-term effects of anterior gastropexy in reducing postoperative recurrence after laparoscopic repair of paraesophageal hernias.

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.
