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.

Laparoscopic repair of paraesophageal hernia

Large paraesophageal hernias are generally repaired by reduction of the stomach into the abdomen, sac excision, crural closure, and gastropexy or fundoplication. After gaining experience performing laparoscopic repair of sliding hiatal hernias and Nissen fundoplication we combined laparoscopic access with traditional surgical technique in treating patients with complex paraesophageal hernias.Ten adults, six males and four females, with type III paraesophageal hernias underwent laparoscopic repair between February 1993 and April 1994. The average age of the patients was 60.4 years (range 38–81). Using five ports (three 10 mm and two 5 mm), the stomach was reduced into the abdomen, the hernia sac was resected, and the defect was closed with pledgeted horizontal mattress sutures. In addition, nine patients had a Nissen fundoplication performed and one patient had a diaphragmatic gastropexy.The procedure was completed laparoscopically in all ten cases and the median operating time was 282 min (range 165–430). Two complications occurred, an intraoperative gastric laceration, and a postoperative mediastinal seroma. All patients were discharged on the 2nd or 3rd postoperative day. Eight of nine patients were asymptomatic at last follow-up (mean 8.9 months postop). One patient has mild dysphagia and heartburn from partial migration of the fundoplication into the chest. One patient died 3 months postoperatively of unrelated causes. Paraesophageal hernia can be reduced and repaired safely with laparoscopic access using standard surgical techniques.Presented at the annual meeting of the Society of American Gastro-intestinal Endoscopic Surgeons (SAGES), Nashville, Tennessee, USA, 18–19 April 1994

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.     

Early robotic experience with paraesophageal hernia repair and Nissen fundoplication: short-term outcomes

The applications of robot-assisted surgery continue to expand. Several recent studies have examined the use of robotic Nissen fundoplication (RF) for treatment of gastroesophageal reflux disease (GERD). Our experience with RF has led us to introduce this technology for the treatment of paraesophageal hernias (PEH). There is little information about the short-term outcomes of patients undergoing robotic paraesophageal hernia repair (RPEH). The goal of our study was to summarize the short-term outcomes of patients who underwent either RF or RPEH. We conducted a retrospective review of all patients who underwent RPEH and RF by a single surgeon between June, 2005 and August, 2006. Data collected included age, gender, body mass index (BMI), co-morbidities and prior operations, and ASA class. Outcomes included operating times, length of stay, pain medication use, and perioperative complications. We performed a comparison of the two groups using the Mann–Whitney U test for statistical significance. Seven patients underwent RPEH, and 19 patients underwent RF alone. Four patients were excluded from the RF group. Patients in the RPEH group had a significantly higher BMI (33 vs. 26 kg/m², P = 0.007) and significantly more comorbidities (6 vs. 4, P = 0.004). There was no calculated statistical difference between the two groups in regards to age, ASA class, operating times, length of stay, or complications. Patients undergoing RPEH have similar short-term outcomes when compared to patients undergoing RF. The skills necessary for RF can be easily applied to RPEH, despite technical differences between the two operations. Similar morbidity can be anticipated between the two groups.

Laparoscopic management of neonatal paraesophageal hernia with intrathoracic gastric volvulus

Intrathoracic gastric volvulus associated with neonatal paraesophageal hernia is very rare in the newborn period. We report a case of a 3-week-old term infant who presented to the hospital with a history of non-bilious vomiting. Workup for hypertrophic pyloric stenosis eventually revealed the presence of a congenital hiatal hernia and intrathoracic gastric volvulus requiring urgent surgical management. The infant underwent successful laparoscopic repair. We discuss the diagnosis and management of this extremely rare surgical cause of neonatal nonbilious emesis.     

Laparoscopic management of large paraesophageal hiatal hernia

Background: Large paraesophageal hernias (POHs) predominantly occur in the elderly population. Early repair is recommended to avoid the risks associated with gastric volvulus. Methods: Data were collected prospectively during an 8-year period. Laparoscopic repair of POHs initially included circumcision of the sac and mesh hiatal repair. Sac excision and suture hiatal repair were later adopted. A fundoplication was also included, initially as a selective procedure. Results: Fifty-three patients with large POHs were treated by one surgeon. All had attempted laparoscopic repair, with four conversions to an open procedure. Symptomatic hernia recurrence occurred in five patients (9%). The 21 patients who had sac excision, hiatal repair, and fundoplication have remained free of symptomatic recurrence. The postoperative morbidity rate was 13%, with one death. Conclusions: Laparoscopic repair of large POHs remains feasible. We advocate complete sac excision, hiatal repair, fundoplication, and gastropexy to prevent early recurrence.     

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     

Recurrent paraesophageal hernia due to diaphragm rupture: a case report

A 58-year-old male patient was operated for complaints of dysphagia, anemia and retrosternal discomfort due to a type II hiatal hernia. A complete hernia sac excision and posterior crural repair was performed laparoscopically with support of the da Vinci™ robotic system. An antireflux procedure was not performed because of the absence of gastroesophageal reflux disease. Nine months after surgery the patient presented with recurrent complaints of dysphagia and retrosternal pain. Barium esophagram series revealed a recurrent paraesophageal hernia which was confirmed on esophagogastroscopy. A robot-assisted re-laparoscopy was performed. Left to the still intact hiatoplasty of the original operation a tear in the diaphragm, through which part of the stomach covered with peritoneum had herniated, was encountered. The hernia sac was excised, the diaphragmatic defect closed and reinforced with an expanded polytetrafluoroethylene strip of 5×8 cm. After surgery the patient recovered quickly, oral intake was resumed on the first postoperative day and the hospital stay was 3 days. The use of prosthetic mesh to reinforce the hiatoplasty and the addition of an antireflux procedure after hiatal hernia repair are ongoing controversial aspects of hiatal hernia repair. Reports on laparoscopic redo surgery for recurrent diaphragmatic hernia are limited and will be addressed in this case report, in perspective of the aforementioned controversial components.

Laparoscopic hiatal hernia repair: why they fail

Summary The incidence of laparoscopic hiatal hernia recurrence has recently been questioned. The results with open repair have been accepted, but increasingly there is interest in mesh reinforcement when performing laparoscopic surgery. Several small series of mesh repair suggest efficacy. Further study of the causes of failure after the laparoscopic approach is warranted and may assist in determining the place of prosthetic reinforcement.     

Use of absorbable meshes in laparoscopic paraesophageal hernia repair

Paraesophageal hernia(PEH) repair is one of the most challenging upper gastrointestinal operations. Its high rate of recurrence is due mostly to the low quality of the crura and size of the hiatal defect. In an attempt to diminish the recurrence rates, some clinical investigators have begun performing meshreinforced cruroplasty with nonabsorbable meshes like polypropylene or polytetrafluoroethylene. The main problem with these materials is the occurrence, in some patients, of serious mesh-related morbidities, such as erosions into the stomach and the esophagus, some of which necessitate subsequent esophagectomy or gastrectomy. Absorbable meshes can be synthetic or biological and were introduced in recent years for PEH repair with the intent of diminishing the recurrence rates observed after primary repair alone but,theoretically, without the risks of morbidities presented by the nonabsorbable meshes. The current role of absorbable meshes in PEH repair is still under debate,since there are few data regarding their long-term efficacy, particularly in terms of recurrence rates, morbidity, need for revision, and quality of life. In this opinion review, we analyze all the presently available evidence of reinforced cruroplasty for PEH repair using nonabsorbable meshes(synthetic or biological),focusing particularly on recurrence rates, mesh-related morbidity, and long-term quality of life.     

Histologic results 1 year after bioprosthetic repair of paraesophageal hernia in a canine model

Background The use of prosthetic materials for the repair of paraesophageal hiatal hernia (PEH) may lead to esophageal stricture and perforation. High recurrence rates after primary repair have led surgeons to explore other options, including various bioprostheses. However, the long-term effects of these newer materials when placed at the esophageal hiatus are unknown. This study assessed the anatomic and histologic characteristics 1 year after PEH repair using a U-shaped configuration of commercially available small intestinal submucosa (SIS) mesh in a canine model. Methods Six dogs underwent laparoscopic PEH repair with SIS mesh 4 weeks after thoracoscopic creation of PEH. When the six dogs were sacrificed 12 months later, endoscopy and barium x-ray were performed, and biopsies of the esophagus and crura were obtained. Results The mean weight of the dogs 1 year after surgery was identical to their entry weight. No dog had gross dysphagia, evidence of esophageal stricture, or reherniation. At sacrifice, the biomaterial was not identifiable grossly. Biopsies of the hiatal region showed fibrosis as well as muscle fiber proliferation and regeneration. No dog had erosion of the mesh into the esophagus. Conclusions This reproducible canine model of PEH formation and repair did not result in erosion of SIS mesh into the esophagus or in stricture formation. Native muscle ingrowth was noted 1 year after placement of the biomaterial. According to the findings, SIS may provide a scaffold for ingrowth of crural muscle and a durable repair of PEH over the long term.

Laparoscopic treatment of large paraesophageal hernias

Background: We set out to evaluate the results of the laparoscopic treatment of large paraesophageal hernias in 22 patients. Methods: Between 1993 and 1998, we operated on 22 consecutive patients. Preoperative assessment consisted of endoscopy, barium esophagogram, 24-h pH testing, manometry, and gastric emptying times. Results: In the first three patients, the sac was not excised and gastropexy was not performed. Because of recurrences, we decided to change the technique in an attempt to avoid further complications. During middle- to long-term follow-up, only three recurrences were seen in the subsequent 19 patients. There were no deaths in this series. Conclusions: Laparoscopic treatment of large paraesophageal hernias is feasible. Because recurrences may occur after successful laparoscopic treatment, both resection of the sac and some form of gastropexy are imperative.

Comparison of patient-centered outcomes after laparoscopic Nissen fundoplication for gastroesophageal reflux disease or paraesophageal hernia

Background Patients undergoing laparoscopic Nissen fundoplication (LNF) with paraesophageal hernias (PEH) are not only older and less healthy than those with gastroesophageal reflux disease (GERD), but in addition the repair is more complicated. We evaluated whether outcomes relating to GERD symptoms and quality of life (QOL) were impacted by the presence of PEH. Methods Prospectively entered data from 149 patients (109 GERD and 40 PEH) were evaluated prior to and one year after LNF with standardized and validated symptoms scores. Scores for heartburn, dysphagia, disease-specific QOL (GERD-HRQL), and general health-related QOL (SF-12 physical and mental component scores) were compared between patients undergoing LNF for PEH or for GERD alone, at baseline and one year after surgery. p < 0.05 was considered statistically significant. Results Preoperative data for GERD-HRQL, heartburn, and dysphagia were available for 134 patients, with 96% one-year follow-up. SF-12 data were collected for 98 patients with 100% follow-up. PEH patients were older and had greater comorbidity. Preoperative GERD-HRQL and heartburn were significantly worse in the GERD group. One year after surgery, both GERD and PEH patients showed significant improvement in GERD-HRQL, heartburn and dysphagia scores, with no difference in any of these disease or symptom measures between the two study groups. Postoperative PCS and MCS scores showed improvement in GERD patients, while PEH patient scores remained at or below the population mean. Conclusions LNF is equally effective as an antireflux procedure in both GERD and PEH patients, prevents symptoms of reflux in PEH patients that have none preoperatively, and does not increase dysphagia in either group. Despite the increased complexity of the procedure, LNF provides an effective control of reflux symptoms in patients undergoing PEH repair.

Single-stage sacral coccygectomy and repair using human acellular dermal matrix (AlloDerm®) with bilateral gluteus maximus flaps for hernia prophylaxis

Sacrococcygectomy is often necessary for the ablation of malignancies involving the sacrum and coccyx, and can result in deep posterior peritoneal defects with disruption of the pelvic floor. Such a radical procedure is frequently associated with significant morbidity, including sacral herniation. Numerous techniques for the closure of the surgical defect have been described, with varying degrees of success in avoiding future herniation. We report the first single-stage coccygectomy and partial sacrectomy with closure utilizing human acellular dermal matrix (HADM) (AlloDerm^®; LifeCell Corporation, Branchburg, NJ) and bilateral gluteus maximus transposition flaps.     

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).     

Laparoscopic repair of large paraesophageal hernia is associated with a low incidence of recurrence and reoperation

Background: Laparoscopic repair of paraesophageal hernia (LRPEH) is a feasible and effective technique. There have been some recent concerns regarding possible high recurrence rates following laparoscopic repair. Methods: We reviewed our experience with LRPEH from 5/1996 to 8/2002. Large paraesophageal hernia (PEH) was defined by the presence of more than one-third of the stomach in the thoracic cavity. Principles of repair included reduction of the hernia, excision of the sac, approximation of the crura, and fundoplication. Pre- and postoperative symptoms were evaluated utilizing visual analogue scores (VAS) on a scale ranging from 0 to 10. Patients were followed with VAS and barium esophagram studies. Statistical analysis was performed using two-tailed Students t-test. Results: A total of 166 patients with a mean age of 68 years underwent LRPEH. PEH were type II (n = 43), type III (n = 104), and type IV (n = 19). Mean operative time was 160 min. Fundoplications were Nissen (127), Toupet (23), Dor (1), and Nissen-Collis (1). Fourteen patients underwent a gastropexy. One patient required early reoperation to repair an esophageal leak. Mean hospital stay was 3.9 days. At 24 months postoperatively there was statistically significant improvement in the mean symptom scores: heartburn from 6.8 to 0.5, regurgitation from 5.9 to 0.3, dysphagia from 4.0 to 0.5, chest pain from 3.7 to 0.3. Radiographic surveillance was obtained in 120 patients (72%) at a mean of 15 months postoperatively. Six patients (5%) had radiographic evidence of a recurrent paraesophageal hernia (two required surgery), 24 patients (20%) had a sliding hernia (two required surgery), and four patients (3.3%) had wrap failure (all four required surgery). Reoperation was required in 10 patients (6%); two for symptomatic recurrent PEH (1.2%), four for recurrent reflux symptoms (2.4%), and four for dysphagia (2.4%). Patients with abnormal postoperative barium esophagram studies who did not require reoperation have remained asymptomatic at a mean follow up of 14 months. Conclusion: LPEHR is a safe and effective treatment for PEH. Postoperative radiographic abnormalities, such as a small sliding hernia, are often seen. The clinical importance of these findings is questionable, since only a small percentage of patients require reoperation. True PEH recurrences are uncommon and frequently asymptomatic.
