Incarcerated paraesophageal hernia. A surgical emergency

Laparoscopic hiatal hernia repair: long-term outcome with the focus on the influence of mesh reinforcement

BACKGROUND

The recurrence rate after laparoscopic repair of hiatal hernias with paraesophageal involvement (LRHP) is reported to be high. Mesh reinforcement has been proposed with the objective of solving this problem. This study aimed to compare the outcome of LRHP before and after the introduction of mesh reinforcement.

METHODS

Between 1992 and 2003, 56 consecutive patients received LRHP including posterior crurorrhaphy and additional fundoplication. Of these 56 patients, 17 underwent a mesh-reinforced hiatoplasty. Perioperative outcome was assessed retrospectively, and follow-up assessment was performed according to protocol including a barium contrast swallow.

RESULTS

The follow-up period averaged 52 +/- 31 months (range, 9-117 months). The recurrence rate for hiatal hernia without mesh reinforcement was 19% (7/36). No recurrence (0/16) was observed in patients with mesh reinforcement. The intraoperative complication rate was 9%, and the perioperative morbidity rate was 14%. There were neither mesh-related complications nor operation-related deaths.

CONCLUSIONS

Although challenging, LRPH is a successful procedure. The high recurrence rate reported in the literature can be reduced by additional mesh reinforcement.

Laparoscopic repair of large hiatal hernias

BACKGROUND

The repair of large hiatal hernias can be technically challenging. Most series describing laparoscopic repair report only symptomatic outcomes and the true recurrence rate, including asymptomatic recurrence, is not well documented. This study evaluated the long-term outcome of laparoscopic repair of large hiatal hernias.

METHODS

All patients who had undergone laparoscopic repair of a large hiatus hernia (more than 50 per cent of the stomach in the hernia) with a minimum 2-year clinical follow-up were identified from a prospectively maintained database. A standardized questionnaire was used to assess symptoms and a barium swallow radiograph was performed to determine anatomy. Multivariate analysis was used to identify factors associated with recurrence.

RESULTS

Of 100 eligible patients, clinical follow-up was available in 96. Follow-up ranged from 2 to 8 (median 4) years. In patients with preoperative reflux symptoms, there were significant improvements in heartburn and dysphagia scores after surgery. Overall, 80 per cent of patients rated their outcome as good or excellent. Sixty patients underwent a postoperative barium meal examination that identified 14 radiological hernia recurrences (eight small, three medium and three large). Four other patients in this group of 60 had previously undergone reoperation for early and late recurrence (two of each), giving an overall recurrence rate of 18 of 60 (30 per cent). One third of patients with recurrence were totally asymptomatic and the presence of postoperative symptoms did not reliably predict the presence of anatomical recurrence. Younger age and increased weight at operation were independent risk factors contributing to recurrence.

CONCLUSIONS

Laparoscopic repair of large hiatal hernias yields good clinical outcome. Recurrence after laparoscopic repair seems to be more common than previously thought. Objective anatomical studies are required to determine the true recurrence rate. The majority of recurrences are not large and do not cause significant symptoms.

Management of Paraesophageal Hernias

A tailored approach to the management of patients who have para-esophageal herniation appears to be the best policy. No one approach can universally apply to this patient population if optimal therapy, quality of life, and overall survival are to be optimized.

Laparoscopic repair of paraesophageal hernia

Laparoscopic repair of paraesophageal hernias is rapidly replacing the traditional open approach. Regardless of the approach, certain aspects of repairing paraesophageal hernias have proven to be beneficial and others remain controversial. This article addresses the effectiveness of the laparoscopic approach, the accepted and controversial technical aspects of repair, and which patients should undergo surgical correction of the hernia.

Mid term analysis of safety and quality of life after the laparoscopic repair of paraesophageal hiatal hernia

BACKGROUND

Initial experience with the laparoscopic repair of paraesophageal and type III mixed hiatal hernias showed that it is safe and feasible, with excellent immediate and short-term results. However, after a longer follow-up, a recurrence rate of < or =40% has been demonstrated. Data related to the outcome of paraesophageal hernia repair and the recurrence rate are still lacking. Quality-of-life scores may offer a better means of assessing the impact of surgical treatment on the overall health status of patients. Therefore, we performed prospective evaluation of anatomic and/or symptomatic recurrences after paraesophageal or large hiatal hernia repair. In addition, we investigated the correlation between recurrence and the patient's quality of life.

METHODS

All patients after who had undergone repair of paraesophageal of mixed hiatal hernia were identified prospectively from a database consisting of all patients who had had laparoscopic operations for gastroesophageal pathology at our hospital between February 1998 and December 2002. The preoperative symptoms were taken from patients' clinical files. In March 2003, all patients with > or =6 months of follow-up had a barium swallow and were examined for radiological and clinical signs of recurrence. Thereafter, the patients' quality of life after surgery was evaluated using three standard questionnaires (Short Form 36 [SF-36], Glasgow Dyspepsia Severity Score [GDSS], and Gastrointestinal Quality of Life Index [GIQLI].

RESULT

During the study period, 46 patients had been operated on. The mean age was 63 years (range, 28-93). Thirty seven of them had a follow-up of > or =6 months. Eight patients (21%) had postoperative gastrointestinal symptoms. Barium swallow was performed in 30 patients (81%) and showed a recurrence in six of them (20%). According to SF-36 and GDSS, the patients' postoperative quality of life reached normal values and did not differ significantly from the standard values for the Spanish population of similar age and with similar comorbidities. Successfully operated patients reached a GIQLI value comparable to the standard population. However, symptomatic patients had significantly lower GIQLI scores than the asymptomatic or the Rx-recurrent group.

CONCLUSION

The laparoscopic treatment of large paraesophageal and mixed hiatal hernias is not only feasible and safe but also offers a good quality of life on a midterm basis. However, the anatomic and functional recurrence rate is high. The next step is to identify the subset of patients who are at risk of failure and to establish technical alternatives that would ensure the durability of the repair.

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 Student's 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.

Laparoscopic repair of paraesophageal hernia with selective use of mesh

The laparoscopic approach to PEH, in use for close to a decade, shows promising results. However, data on the long-term follow-up of patients who undergo this procedure are still lacking, and the use of mesh is debatable. We retrospectively investigated 33 patients who underwent this procedure over a 30-month period. In 10 patients, the repair was performed using a mesh prosthesis. There was one (3%) intraoperative and four (12%) early postoperative complications, with one mortality (3%). The average postoperative stay was 3 days. During a 58-month follow-up period, 18% of the patients developed small, sliding recurrent hernias, with a higher rate in the primary repair group (18% vs. 10%). Surgical outcome was scored good-to-excellent on a questionnaire by 84.5% of the patients. Laparoscopic repair of PEH is feasible and safe. While small recurrences do occur, functional results remain good. The use of mesh should be tailored to the specific patient.

Diaphragmatic herniation after transhiatal esophagectomy

Increasing experience with transhiatal esophagectomy (THE) has brought with it a good understanding of the advantages and disadvantages of the technique. As in our case, diaphragmatic hernias after THE may result from excess manipulation and extension of the hiatus during surgery. The varying nature of the clinical presentation may cause delay in diagnosis. We report our case and discuss how to diagnose and manage this complication under the sum of cases reported previously in English literature.

Laparoscopic paraesophageal hernia repair, a challenging operation: medium-term outcome of 116 patients

Laparoscopic paraesophageal hernia repairs performed in 116 patients between 1992 and 2001 were prospectively analyzed. Perioperative outcomes were assessed and follow-up was performed under protocol. There were 85 female and 31 male patients who had a mean (+/- SD) age of 65 +/- 13 years and an American Society of Anesthesiology score of 2.3 +/- 0.6. All but two patients underwent an antireflux procedure. Gastropexy was performed in 48 patients, an esophageal lengthening procedure in six patients, and prosthetic closure of the hiatus in six patients. Major complications occurred in five patients (4.3%) with two postoperative deaths (1.7%). Mean follow-up was 30 +/- 25 months; 96 patients (83%) have been followed for more than 6 months. Among these patients, 73 (76%) are asymptomatic, 11 (11%) have mild symptoms, and 12 (13%) take antacid medications. Protocol barium esophagograms were obtained in 69% of patients at 6 to 12 months' follow-up. Recurrence of hiatal hernia was documented in 21 patients (22% overall and in 32% of those undergoing contrast studies). Reoperation has been performed in three patients (3%). When only the patients with recurrent hiatal hernias are considered, 13 (62%) are symptomatic but only six (28%) require medication for symptoms. Laparoscopic paraesophageal hernia repair is generally safe, even in this high-risk group. This study confirms a relatively high incidence of recurrent hiatal abnormalities after paraesophageal hernia repair; however, most recurrent hiatal hernias are small and only 3% have required reoperation. Protocol esophagograms detect recurrences that are minimally symptomatic. Improved techniques must be devised to improve the long-term outcomes of laparoscopic paraesophageal hernia repair.

Results of laparoscopic repair of giant paraesophageal hernias: 200 consecutive patients

BACKGROUND

Giant paraesophageal hernias (GPEH) have traditionally required open operations. Increasingly, a laparoscopic approach is being applied to more complex esophageal surgery. Our objective was to update our growing experience with laparoscopic repair of GPEH.

METHODS

We performed a retrospective review at our institution of patients undergoing laparoscopic repair of GPEH from July 1995 to July 2001. The GPEH was defined as greater than one-third of the stomach in the chest.

RESULTS

Elective laparoscopic repair of a GPEH was attempted in 203 patients. Mean age was 67 years. The most common symptoms included heartburn (96 patients), dysphagia (72), epigastric pain (56), and vomiting (47 patients). Laparoscopic procedures included 69 Nissens, 112 Collis-Nissens, and 19 other procedures. There were three open conversions due to adhesions, but no intraoperative emergencies. Median length of stay was 3 days (range, 1 to 120 days). Minor or major complications occurred in 57 patients (28%). There were six postoperative esophageal leaks (3%), and 1 death. Median follow-up was 18 months. Five patients required reoperation for recurrent hiatal hernia. Excellent results were reported in 128 (84%) patients, 12 (8%) had a good result, 7 (5%) fair, and 5 (3%) poor (based on postoperative follow-up and GERD questionnaire). The mean postoperative GERD Health-related Quality of Life Score was 2.4 (scale 0 to 45; 0 = no symptoms, 45 = worst).

CONCLUSIONS

Laparoscopic repair of GPEH is possible in the majority of patients with acceptable morbidity, a median length of hospital stay of 3 days and excellent intermediate-term results in an experienced center.

Paraesophageal hernias: operation or observation?

OBJECTIVE

To examine the hypothesis that elective laparoscopic repair should be routinely performed on patients with asymptomatic or minimally symptomatic paraesophageal hernias.

SUMMARY BACKGROUND DATA

The management of asymptomatic paraesophageal hernias is a controversial issue. Most surgeons believe that all paraesophageal hernias should be corrected electively on diagnosis, irrespective of symptoms, to prevent the development of complications and avoid the risk of emergency surgery.

METHODS

A Markov Monte Carlo decision analytic model was developed to track a hypothetical cohort of patients with asymptomatic or minimally symptomatic paraesophageal hernia and reflect the possible clinical outcomes associated with two treatment strategies: elective laparoscopic paraesophageal hernia repair (ELHR) or watchful waiting (WW). The input variables for ELHR were estimated from a pooled analysis of 20 published studies, while those for WW and emergency surgery were derived from the 1997 HCUP-NIS database and surgical literature published from 1964 to 2000. Outcomes for the two strategies were expressed in quality-adjusted life-years (QALYs).

RESULTS

Analysis of the HCUP-NIS database showed that published studies overestimate the mortality of emergency surgery (17% vs. 5.4%). The mortality rate of ELHR was 1.4%. The annual probability of developing acute symptoms requiring emergency surgery with the WW strategy was 1.1%. For patients 65 years of age, ELHR resulted in reduction of 0.13 QALYs (10.78 vs. 10.65) compared with WW. The model predicted that WW was the optimal treatment strategy in 83% of patients and ELHR in the remaining 17%. The model was sensitive only to alterations of the mortality rates of ELHR and emergency surgery.

CONCLUSIONS

If ELHR is routinely recommended, it would be more beneficial than WW in fewer than one of five patients. WW is a reasonable alternative for the initial management of patients with asymptomatic or minimally symptomatic paraesophageal hernias, and even if an emergency operation is required, the burden of the procedure is not as severe as was thought in the past.

Mesh Crural Repair of Large Paraesophageal Hiatal Hernias

Surgical repair is indicated in patients with paraesophageal hernias but is associated with a high recurrence rate. Our objective was to assess the safety and efficacy of mesh reinforcement of the crural closure in laparoscopic paraesophageal hernia repair. We conducted a 7-year retrospective review of all patients undergoing laparoscopic paraesophageal hernia repair with or without use of mesh. The main outcome measures were use of mesh, reason for use, age, sex, preoperative symptoms, length of operation, length of hospital stay, postoperative complications, and long-term follow-up conducted by physician interview. Twelve patients were repaired with mesh (Group A) and 12 without (Group B). Age, sex, operating time, length of hospital stay, and postoperative complications were similar in both groups. In Group A two patients required an interposition graft and ten required mesh reinforcement of the crural closure. One Group A patient developed an early recurrence requiring a reoperation, and one Group B patient developed a gastric leak where the fundus was sutured to the crura. The remainder of the patients experienced resolution of their symptoms at 2 weeks follow-up. Long-term follow-up (average 37 months) showed one Group B patient with a recurrence of reflux symptoms, but an upper gastrointestinal study showed no recurrence of hernia. All others remained asymptomatic. We conclude that the use of mesh in laparoscopic repair of large paraesophageal hernias appears safe and may reduce recurrence.

Minimally invasive management of paraesophageal herniation in the high-risk surgical patient

BACKGROUND

Traditional management of symptomatic paraesophageal herniation involves hernia reduction, hiatal closure, and an antireflux procedure or gastropexy. Patients with significant comorbidities may not tolerate operative repair. A new technique, laparoscopic-assisted endoscopic reduction and fixation of the stomach, may provide a minimally invasive treatment alternative.

METHODS

Eleven elderly patients with symptomatic paraesophageal herniation were managed with flexible endoscopy and double percutaneous endoscopic gastrostomy (PEG) tube insertion with or without laparoscopic assistance.

RESULTS

All patients presented with a symptomatic paraesophageal hernia. Mean age was 78.3 years (range 72 to 84). Each was deemed at high risk for definitive repair due to preexisting coronary artery disease as well as at least two other serious comorbidities. Hernia reduction and intra-abdominal fixation of the stomach was achieved in each case using flexible endoscopy and double PEG insertion. Laparoscopic assistance for reduction and gastropexy was utilized in 9 cases. Mean operative time was 61 minutes (range 28 to 104). Average length of stay was 2.8 days (range 0 to 12). One minor and three major postoperative complications occurred. Over a mean follow-up of 4.1 months (range 2 to 7), all patients have resumed oral intake and achieved weight gain.

CONCLUSIONS

Patients with symptomatic paraesophageal herniation require intervention to alleviate symptoms and avoid the complications of gastric incarceration. For the high-risk patient, endoscopic reduction and PEG with laparoscopic assistance appears to provide effective treatment.

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 repair of chronic intrathoracic gastric volvulus

BACKGROUND

Totally intrathoracic gastric volvulus is an uncommon presentation of hiatal hernia, in which the stomach undergoes organoaxial torsion predisposing the herniated stomach to strangulation and necrosis. This may occur as a surgical emergency, but some patients present with only chronic, non-specific symptoms and can be treated electively. The aim of this study is to describe a comprehensive approach to laparoscopic repair of chronic intrathoracic gastric volvulus and to critically assess the pre-operative work-up.

METHODS

Eight patients (median age, 71 years) underwent complete laparoscopic repair of chronic intrathoracic gastric volvulus. Symptoms of epigastric pain and early satiety were universally present. Five patients had reflux symptoms. The diagnostic evaluation included a video esophagogram, upper endoscopy, 24-hour pH measurement, and esophageal manometry in all patients. Operative results and postoperative outcome were recorded and follow-up at 1 year included a barium swallow in all patients.

RESULTS

All patients had documented intrathoracic stomach. Five of 8 patients had a structurally normal lower esophageal sphincter. All 4 patients with reflux esophagitis on upper endoscopy had a positive 24-hour pH study, and 2 of these patients had a structurally defective lower esophageal sphincter on manometry. None of the patients had preoperative evidence of esophageal shortening. All procedures were completed laparoscopically. The procedure included reduction of the stomach into the abdomen, primary closure of the diaphragmatic defect, and the construction of a short, floppy Nissen fundoplication. There were no major complications. One patient required repair of a trocar site hernia 6 months postoperatively. At 1-year follow-up, there were no radiologic recurrences of the volvulus. One patient complained of temporary swallowing discomfort and another had recurrent gastroesophageal reflux disease (GERD) symptoms caused by a breakdown of the wrap. All other patients remained asymptomatic during follow-up.

CONCLUSIONS

The repair of chronic gastric volvulus can be accomplished successfully with a laparoscopic approach. A preoperative endoscopy and esophagogram are crucial to detect esophageal stricture or shortening, and manometry is needed to access esophageal motility; pH measurements do not affect operative strategy. The procedure should include a Nissen fundoplication to treat preoperative GERD, to prevent possible postoperative GERD, and to secure the stomach in the abdomen. The procedure is safe but technically challenging, requiring previous laparoscopic foregut surgical expertise.

Laparoscopic repair of giant paraesophageal hernia: 100 consecutive cases

OBJECTIVE

To summarize the authors' laparoscopic experience for paraesophageal hernia (PEH).

SUMMARY BACKGROUND DATA

Laparoscopic antireflux surgery and repair of small hiatal hernias are now routinely performed. Repair of a giant PEH is more complex and requires conventional surgery in most centers. Giant PEH accounts for approximately 5% of all hiatal hernias. Medical management may be associated with a 50% progression of symptoms and a significant death rate. Conventional open surgery has a low death rate, but complications are significant and return to routine activities is delayed in this frequently elderly population. Recently, short-term outcome studies have reported that minimally invasive approaches to PEH may be associated with a lower complication rate, a shorter hospital stay, and faster recovery.

METHODS

From July 1995 to February 2000, 100 patients (median age 68) underwent laparoscopic repair of a giant PEH. Follow-up included heartburn scores and quality of life measurements using the SF-12 physical component and mental component summary scores.

RESULTS

There were 8 type II hernias, 85 type III, and 7 type IV. Sac removal, crural repair, and antireflux procedures were performed (72 Nissen, 27 Collis-Nissen). The 30-day death rate was zero; there was one surgery-related death at 5 months from a perioperative stroke. Intraoperative complications included pneumothorax, esophageal perforation, and gastric perforation. There were three conversions to open surgery. Major postoperative complications included stroke, myocardial infarction, pulmonary emboli, adult respiratory distress syndrome, and repeat operations (two for abscess and one each for hematoma, repair leak, and recurrent hernia). Median length of stay was 2 days. Median follow-up at 12 months revealed resumption of proton pump inhibitors in 10 patients and one repeat operation for recurrence. The mean heartburn score was 2.3 (0, best; 45, worst); the satisfaction score was 91%; physical and mental component summary scores were 49 and 54, respectively (normal, 50).

CONCLUSION

This report represents the largest series to date of laparoscopic repair of giant PEH. In the authors' center with extensive experience in minimally invasive surgery, laparoscopic repair of giant PEH was successfully performed in 97% of patients, with a minimal complication rate, a 2-day length of stay, and good intermediate results.

A 32-year experience in 100 patients with giant paraesophageal hernia: the case for abdominal approach and selective antireflux repair

BACKGROUND

Giant paraesophageal hiatal hernia (GPEH) presents a risk of catastrophic complications that include massive bleeding, strangulation, and perforation and should be repaired. Controversy persists as to the surgical approach and whether an antireflux repair is required.

METHODS

This study reviews the experience with 100 patients with GPEH who underwent surgical repair between 1967 and 1999. Eighty patients underwent an elective operation, and 20 patients underwent an emergency procedure for complications of GPEH. The gastroesophageal junction was above the hiatus ("combined" hernia with sliding component) in 23 patients and in the abdomen in 77 patients, including 3 patients with a true parahiatal hernia.

RESULTS

A thoracic approach was used in 18 patients, mostly early in our experience; postoperative gastric volvulus requiring transabdominal repair developed in 2 patients. The remaining 82 patients underwent an abdominal repair, with temporary gastrostomy to prevent gastric displacement in 75 patients; the hernial sac was resected, and the hiatus was reconstructed in all of the patients. Thirty-five patients with reflux on preoperative work up underwent a fundoplication, with gastroplasty in 2 patients because of a short esophagus. No patient has experienced hernia recurrence. Whereas symptomatic relief was excellent in all patients with elective repair, mild reflux was present in 2 patients after emergency operation. There were no deaths among the patients who underwent elective operation; there were 2 hospital deaths among those patients who underwent emergency operation (10%).

CONCLUSIONS

GPEH should be repaired soon after recognition. Reflux should be evaluated before the operation, and if present, fundoplication should be part of the repair along with the reduction of the hernia, excision of the sac, gastropexy, and crural closure. These are best achieved with an abdominal approach.

Characterization and management of paraesophageal hernias in children after antireflux operation

PURPOSE

The aim of this study was to determine the important factors in the development and subsequent treatment of postoperative paraesophageal hernia (PPEH).

METHODS

A retrospective analysis was performed in 464 consecutive children (ages 3 days to 18 years) for PPEH after a primary antireflux operation performed at a Children's Hospital and University Hospital between 1985 and 1997. All operations included a crural repair, but the Nissen fundoplication was performed with (n = 162) and without (n = 70) plication of the esophagus to the crus at 3 points. Patients with and without PPEH were compared with respect to the type of antireflux operation, the patient's age at operation, and the preoperative and postoperative clinical courses. A preoperative corrected gastric emptying value was obtained from a radionuclide gastric emptying study in 289 patients. The treatment of PPEH also was examined.

RESULTS

The incidence of PPEH in our patients was 4.5% (21 of 464). Although there was a lower incidence of PPEH in patients with crural plication compared with patients without crural plication during Nissen fundoplication (5 of 162, 3% v 7 of 70, 10%; P = .035), 2 patients with crural plication had a postoperative esophageal leak. Patients with PPEH had a significantly increased prevalence of gagging before the initial antireflux operation compared with patients without PPEH (3 of 21, 14.3% v 7 of 443, 1.6%; P = .007). A higher prevalence of slow corrected gastric emptying preoperatively also was seen in patients with PPEH compared with patients without PPEH (8 of 15, 53% v 79 of 274, 29%; P = .046). The prevalences of central nervous system disease, young age (<6 months) at initial operation, and a particular type of antireflux operation were not higher in patients with PPEH. Nine patients with a small PPEH treated by simple observation alone subsequently had resolution of symptoms.

CONCLUSIONS

Patients who have gagging or slow corrected gastric emptying before an antireflux operation are at higher risk for a postoperative paraesophageal hernia. Patients with a small postoperative paraesophageal hernia can be treated nonoperatively. Crural plication of the esophagus during Nissen fundoplication reduces the occurrence of postoperative paraesophageal hernia, but also may result in significant morbidity.

Paraesophageal hernia in an elderly woman with vomiting

We describe the case of a 79-year-old woman who presented with resolved episodes of vomiting and was found to have a paraesophageal hernia. Her initial evaluation was unremarkable, and the diagnosis was established only by the use of screening chest radiography. Once the diagnosis was confirmed, the patient required urgent surgical repair. Paraesophageal hernia is a rare clinical entity with the potential for life-threatening complications, making the diagnosis itself an indication for surgery. This case illustrates the fact that significant pathology may be present with few, if any, physical findings in the elderly patient, and thorough evaluations are required for the diagnosis of such occult pathology.

Current concepts in the management of paraesophageal hiatal hernia

Herniation of a portion of the stomach through the esophageal hiatus into the posterior mediastinum is a common affliction of humans. The incidence of hiatal hernia is difficult to determine because of the absence of symptoms in a large number of patients. Upper gastrointestinal barium examinations in symptomatic patients identify some type of hiatal hernia in as many as 15% of patients.

Repair of paraesophageal hernias

BACKGROUND

Three years ago we proposed the use of laparoscopy and systematic addition of an antireflux procedure to repair paraesophageal hernias. We now present an analysis of the outcome on patients and the evolution of the technique proposed.

METHODS

Symptoms and esophageal function were prospectively collected and followed in 41 consecutive patients treated over a 4-year period. Indications for repair included chronic anemia in 15 patients, and previous incarceration in 8. Twenty-two patients had symptoms of reflux.

RESULTS

All operations were started laparoscopically, two were converted. Mean operating time was 210 minutes, and mean hospital stay was 4 days. Mean follow-up was 3 years. The operation was effective; all symptoms had improved significantly at last follow-up.

CONCLUSIONS

Laparoscopic repair of paraesophageal hernia with the addition of an antireflux procedure, although difficult, lengthy, and not totally without risk, improves symptoms substantially, resolves anemia, and prevents incarceration in nearly all patients.

Diaphragmatic herniation following oesophagectomy

BACKGROUND

Intrathoracic herniation of abdominal viscera is a potentially life-threatening condition, especially when diagnosis is delayed. The aim of this study was to estimate its incidence following oesophageal resection and to define contributing factors that might influence its occurrence.

METHODS

All radiographic studies of the chest that were made during follow-up in a series of 218 patients who underwent oesophagectomy between 1993 and 1997 were reviewed.

RESULTS

Herniation of bowel alongside the oesophageal substitute was detected in nine patients (4 per cent). Four hernias occurred within the first week after operation and five were detected at late follow-up. Surgical treatment was indicated in six patients. Analysis of predisposing factors revealed that extended incision and partial resection of the diaphragm were associated with an increased risk of postoperative hernia formation (four of 29 following extended enlargement versus five of 189 after routine opening of the oesophageal hiatus; P = 0.02).

CONCLUSION

Diaphragmatic herniation was found in 4 per cent of patients after oesophagectomy. After extended iatrogenic disruption of the normal hiatal anatomy, narrowing of the diaphragmatic opening may be indicated to avoid postoperative herniation of bowel into the chest. Awareness of its possible occurrence may help prevent the development of intestinal obstruction and strangulation.

Durability of laparoscopic repair of paraesophageal hernia

OBJECTIVES

To define a method of primary repair that would minimize hernia recurrence and to report medium-term follow-up of patients who underwent laparoscopic repair of paraesophageal hernia to verify durability of the repair and to assess the effect of inclusion of an antireflux procedure.

SUMMARY BACKGROUND DATA

Primary paraesophageal hernia repair was completed laparoscopically in 55 patients. There were five recurrences within 6 months when the sac was not excised (20%). After institution of a technique of total sac excision in 30 subsequent repairs, no early recurrences were observed.

METHODS

Inclusion of an antireflux procedure, incidence of subsequent hernia recurrence, dysphagia, and gastroesophageal reflux symptoms were recorded in clinical follow-up of patients who underwent a laparoscopic procedure.

RESULTS

Mean length of follow-up was 29 months. Forty-nine patients were available for follow-up, and one patient had died of lung cancer. Mean age at surgery was 68 years. The surgical morbidity rate in elderly patients was no greater than in younger patients. Eleven patients (22%) had symptoms of mild to moderate reflux, and 15 were taking acid-reduction medication for a variety of dyspeptic complaints. All but 2 of these 15 had undergone 360 degrees fundoplication at initial repair. Two patients (4%) had late recurrent hernia, each small, demonstrated by esophagram or endoscopy.

CONCLUSIONS

Laparoscopic repair in the medium term appeared durable. The incidence of postsurgical reflux symptoms was unrelated to inclusion of an antireflux procedure. In the absence of motility data, partial fundoplication was preferred, although dysphagia after floppy 360 degrees wrap was rare. With the low morbidity rate of this procedure, correction of symptomatic paraesophageal hernia appears indicated in patients regardless of age.

Laparoscopic treatment of large paraesophageal hernia with totally intrathoracic stomach

BACKGROUND

Once paraesophageal hernia has been diagnosed, it should be repaired immediately because of life-threatening complications such as bleeding, ischemia, and perforation when intrathoracic strangulation or volvulus occurs. We describe our surgical strategy for treating this rare type of hiatal hernia with regard to early and late postoperative complications.

STUDY DESIGN

This was a retrospective case series from a university hospital. Twelve patients (seven women and five men) with a mean age of 64 years (range, 50-76 years) and a completely intrathoracic stomach underwent laparoscopic paraesophageal hernia repair. Seven patients had a type 2 hernia, and five patients had a type 3 hernia. Additional organoaxial volvulus was present in three patients. All patients underwent reduction of the stomach and the greater omentum, excision of the hernia sac, closure of the hiatal defect, and a floppy Nissen fundoplication.

RESULTS

Because of severe adhesions, one patient needed an open stomach reduction (conversion rate, 8%). The mean operating time was 161 minutes (range, 110-200 minutes), blood loss was minimal, and the mean postoperative hospital stay was 6 days (range, 4-7 days). There were no intraoperative complications, but early postoperative complications occurred in three patients (25%; one with dysphagia, 1 reoperation due to organoaxial gastric rotation with gastroduodenal obstruction, and one with deep venous thrombosis). No deaths occurred. Followup in all patients is complete, with a mean followup time of 21 months (range, 3-40 months). The complication rate after long-term followup was 8%, and reflux esophagitis symptoms in one patient were completely relieved by medical therapy.

CONCLUSIONS

Laparoscopic paraesophageal hernia repair was feasible and safe with low morbidity and mortality rates in this elderly patient group. To achieve good long-term results, standard surgical treatment should include reduction of the stomach, complete excision of the hernia sac, closure of the hiatal defect, floppy Nissen fundoplication, and anterior gastropexy.

Oesophageal hiatal hernia-induced hydropneumothorax

The patient presented with acute and constant abdominal pain. He had had a lobectomy of the left lung three months before. On the 4th day in hospital the pain increased and he went into temporary shock. The next day a hydropneumothorax and incarcerated stomach were revealed by chest X-ray and computed tomography. He was transferred to the University Hospital immediately and underwent an operation. The diagnosis was an incarcerated para-oesophageal hernia with hydropneumothorax and perforation of the stomach. As a para-oesophageal hernia may be fatal, it is important to diagnose and treat it early.

Simple laparoscopic gastropexy as the initial treatment of paraoesophageal hiatal hernia

BACKGROUND

Paraoesophageal hiatal hernia is relatively rare compared with sliding hernia but it is associated with serious complications. Its clinical management presents a major challenge since many patients are elderly and unfit for a formal repair. This paper describes a laparoscopic method aimed at reducing the complications of open repair.

METHODS

Thirteen patients treated for symptomatic paraoesophageal hernia were included in the study. Eleven patients successfully underwent a simple laparoscopic modification of the Boerema anterior gastropexy. Two patients required an open anterior gastropexy through a minilaparotomy because of incomplete reduction of the hernia. A five-puncture technique was used. The stomach and any other contents of the sac were reduced into the abdomen and the stomach was firmly fixed to the fascia of the anterior abdominal wall with GORE-TEX sutures tied extracorporeally.

RESULTS

There was one postoperative death due to spontaneous intrathoracic perforation of the posterior aspect of the stomach in an elderly woman with severe cardiac disease. There was no postoperative morbidity. Eight of the ten patients who went home following laparoscopic gastropexy have remained asymptomatic on follow-up. In three patients, two in the laparoscopic group and one in the open group, symptoms recurred.

CONCLUSION

While anterior gastropexy has a significant incidence of recurrent herniation, the clinical results of this simple procedure in a high-risk population support its use as the initial surgical option.

Massive hiatus hernia: evaluation and surgical management

OBJECTIVE

Paraesophageal hernias represent advanced degrees of sliding hiatus hernia with intrathoracic displacement of the intraesophageal junction. Gastroesophageal reflux disease occurs in most cases, resulting in acquired short esophagus, which should influence the type of repair selected.

METHODS

Between 1960 and 1996, 94 patients with massive, incarcerated paraesophageal hiatus hernia were operated on at the Toronto General Hospital. The mean age was 64 years (39 to 85 years), with a female to male ratio of 1.8:1. Organoaxial volvulus was present in 50% of cases. Clinical presentation in these patients included postprandial pain in 56%, dysphagia in 48%, chronic iron deficiency anemia in 38%, and aspiration in 29%. Symptomatic reflux, either present or remote, was recorded in 83% of cases. All patients underwent endoscopy by the operating surgeon. In 91 of 94 patients, the esophagogastric junction was found to be above the diaphragmatic hiatus, denoting a sliding type of hiatus hernia. Gross, endoscopic peptic esophagitis was observed in 36% of patients: ulcerative esophagitis in 22% and peptic esophagitis with stricture in 14%. A complete preoperative esophageal motility study was obtained for 41 patients. The lower sphincter was hypotensive in 21 patients (51%), and the amplitude of peristalsis in the distal esophagus was diminished in 24 patients (59%). These abnormalities are both features of significant gastroesophageal reflux disease. In 13 recent, consecutive patients with paraesophageal hernia, the distance between the upper and lower esophageal sphincters was measured during manometry. The average distance was 15.4 +/- 2.33 cm (11 to 20 cm), which is consistent with acquired short esophagus. The normal distance is 20.4 cm +/- 1.9 (p < 0.0001).

RESULTS

All 94 patients were treated surgically: 97% had a transthoracic repair with fundoplication. A gastroplasty was added in 75 cases (80%) because of clearly defined or presumed short esophagus. There were two operative deaths, and two patients were never followed up. Among the 90 available patients, the mean follow-up was 94 months; median follow-up was 72 months. Seventy-two patients (80%) are free of symptoms (excellent result); 13 (13%) have inconsequential symptoms requiring no therapy (good result); and three patients (4%) are improved but have symptoms requiring medical therapy or interval dilatation (fair result). Two patients had poor results because of recurrent hernia and severe reflux. Both were successfully treated by reoperation with the addition of gastroplasty because of acquired shortening, which was not recognized at the first operation.

CONCLUSIONS

Most of these 94 patients had symptoms or endoscopic, manometric, and operative findings that were consistent with a sliding hiatus hernia. There was a high incidence of endoscopic reflux esophagitis and of acquired short esophagus. True paraesophageal hernia, with the esophagogastric junction in a normal abdominal location, appears rare. Our observations were supported by measurements obtained at preoperative endoscopy and manometry, and by findings at the time of surgical repair. These observations support the choice of a transthoracic approach for repair in most patients.

Laparoscopic treatment of gastric volvulus: a case report

A case report of laparoscopic treatment of gastric volvulus in an 85-year-old man is presented. The patient did not have intraoperative or postoperative complications, tolerated a diet in 48 hours, and was discharged home 4 days after surgery. A gastric volvulus can be safely treated using laparoscopic techniques.

Hiatal hernia with cameron ulcers and erosions

Cameron lesions are seen in 5.2% of patients with hiatal hernias who undergo EGD examinations. The prevalence of Cameron lesions seems to be dependent on the size of the hernia sac, with an increased prevalence the larger the hernia sac. In about two thirds of the cases, multiple Cameron lesions are noted rather than a solitary erosion or ulcer. Historically, Cameron lesions present clinically with chronic GI bleeding and associated iron deficiency anemia. With increased awareness of the existence of this lesion, however, it is now more frequently seen as an incidental finding during EGD. Cameron lesions can also present as acute upper GI bleeding, occasionally life-threatening, in up to one third of cases. Therefore, Cameron lesions should be considered in any patient in whom a hiatal hernia is noted during endoscopic examination. Concomitant acid-peptic diseases are seen in a majority of individuals, especially reflux esophagitis and its complications. Mechanical trauma, ischemia, and acid mucosal injury may play a role in the pathogenesis of Cameron lesions. The choice of therapy of Cameron lesions, medical or surgical, should be individualized for each patient. Of those patients who were treated with a spectrum of medical therapy and who have had long-term follow-up, about one third have had a recurrence of the lesion and 17% (8/48) have developed complications, most commonly either acute upper GI bleeding (6.3%) or persistent and recurrent iron deficiency anemia (8.3%).

Laparoscopic management of paraesophageal hernia: early results

The objective was to review our early results with laparoscopic repair of paraesophageal hernias to determine the safety, technical feasibility, and short-term outcome of the operation. Twelve patients with a mean age of 75 +/- 1 years underwent laparoscopic repair of a paraesophageal hernia. Principles of open repair, including sac excision, primary crural repair, and pexy, were accomplished laparoscopically in 83%, 83%, and 100% of patients, respectively. In two patients the diaphragmatic defect was closed with mesh. Fundoplication was also performed in seven patients with symptoms of reflux disease. No laparoscopic procedure was converted to an open repair; however, one patient required a postoperative celiotomy to control hemorrhage. Short-term evaluation of all patients postoperatively detected gastroesophageal reflux disease (GERD) in five patients (42%), four of whom did not undergo fundoplication. Two major complications were esophageal perforation and bleeding. Minor complications included atrial fibrillation in two patients, meat impaction in one patient, and a small asymptomatic recurrence in a single patient. Overall patient satisfaction was high. Laparoscopic repair of paraesophageal hernias was safe and technically feasible and warrants further investigation. The incidence of postoperative esophageal reflux, however, is high if an antireflux procedure is not performed. Extensive preoperative evaluation for reflux should objectively identify patients requiring fundoplication and decrease the incidence of postoperative GERD.

Systematic use of gastric fundoplication in laparoscopic repair of paraesophageal hernias

BACKGROUND

Early surgical treatment has been recommended in patients with paraesophageal hiatal hernias. Recently, the laparoscopic approach has emerged as an ideal way to perform the operation. But whether or not an antireflux procedure should be done remains controversial.

PATIENTS AND METHODS

Four patients with type II and eleven with type III hiatal hernias were treated. Twelve of them manifested symptoms of reflux preoperatively. The operative technique consisted of resection of the sac, closure of the crura and gastric fundoplication, anchored to the diaphragm.

RESULTS

All but two patients were completed laparoscopically. Mean operative time was 320 (+/-49 SD) minutes, and mean hospital stay was 3 (+/-1.2 SD) days. Early postoperative complications were subcutaneous emphysema (two patients) and atrial fibrillation (one patient). At one year all patients were asymptomatic without dysphagia, reflux, or recurrence of the hernia.

CONCLUSION

The addition of fundoplication to paraesophageal hernia repair restores competency of the sphincter in patients with reflux associated to the hernia and prevents postoperative gastroesophageal reflux that results from the extensive dissection required. In addition, it provides an ideal means of fixing the stomach in the subdiaphragmatic position, decreasing the long term-risk of recurrence.

Management of paraesophageal hernia with a selective approach to antireflux surgery

BACKGROUND

The role of an antireflux procedure in the management of paraesophageal hernia is controversial. To address this issue, we reviewed our experience with selective use of antireflux procedures in patients with pure paraesophageal hernia (type II; n = 26) and those with a partial sliding component (type III; n = 11).

PATIENTS AND METHODS

Surgical repair was performed on diagnosis in all 37 patients. Competency of the lower esophageal sphincter was evaluated on the basis of reflux symptoms, and objectively, with endoscopy in 21 patients and 24-hour esophageal pH studies in 17 patients. Repair included an antireflux procedure in 11 patients, as indicated by reflux disease.

RESULTS

Preoperatively, 80% of both type II and type III patients reported obstructive symptoms. Reflux symptoms were present in 27% of patients--19% of type II and 45% of type III patients. Endoscopy revealed esophagitis in 5 cases, and 24-hour pH studies indicated significant reflux in 3 of 17 patients. There were no operative deaths and 1 recurrence. Symptoms improved in 92% of patients after surgery. Medically manageable reflux was identified in 2 patients.

CONCLUSIONS

Frequent obstructive symptoms and the potential for gastric volvulus indicate elective repair of paraesophageal hernia on diagnosis. Significant gastroesophageal reflux is less common, especially in type II patients, and excellent symptomatic results are obtained with selective application of an antireflux procedure.

Strangulated parahiatal hernia: not just another paraesophageal hernia

Exploratory thoracotomy was necessary to establish the diagnosis of a rare incarcerated parahiatal hernia. Symptomatology, signs, and radiographic findings are compared with those of paraesophageal hernias.

Paraesophageal hiatal hernia: is an antireflux procedure necessary?

Between January 1970 and October 1992, 119 patients underwent 126 repairs of a paraesophageal hiatal hernia at the Lahey Clinic. Seven patients with a recurrent hernia required reoperation. Of the procedures, 19 (15%) included an antireflux procedure because of severe reflux symptoms and objective evidence of reflux demonstrated by grade 2 esophagitis on endoscopy, manometric evidence of a hypotensive lower esophageal sphincter pressure (< or = 10 mm Hg), positive results on 24-hour pH monitoring, or all three methods. Follow-up ranged from 6 months to 18 years with a median of 61.5 months, and the results of 115 operations were analyzed. Symptomatic results were good to excellent after 96 (83.5%) of these 115 operations. Thirteen symptomatic paraesophageal hernias recurred in 12 patients (one recurrence per 58 patient-years of follow-up). Severe reflux symptoms accompanied by endoscopic evidence of esophagitis developed in 2 patients who had not undergone an antireflux procedure at the time of repair of the hernia. We conclude that an antireflux procedure is rarely required in patients undergoing repair of a paraesophageal hiatal hernia and should be employed only when objective evidence of reflux is seen preoperatively.

Paraesophageal hernia in an elderly woman

We present a case of an elderly woman with a paraesophageal hernia. This is an uncommon type of hiatal hernia and may result in a surgical emergency if incarceration, obstruction, or strangulation is present. Our patient presented with a clinical picture consistent with myocardial ischemia. We discuss the differential diagnosis, the pathophysiology, complications, diagnostic studies, and treatment of this disease.

Congenital diaphragmatic hernia presenting due to gastrointestinal complications

Congenital diaphragmatic hernia (CDH) presents beyond the first hours of life in 10% to 20% of cases. Presenting symptoms may be quite nonspecific, and are often gastrointestinal rather than respiratory in origin. We have recently had experience with five such cases, one in a newborn and four in older children. All presented with symptoms related to gastrointestinal complications of their diaphragmatic defect. In the newborn, gastric perforation had occurred, a complication of this anomaly not previously reported. The chest radiograph showed loops of bowel in the chest in all cases, allowing correct preoperative diagnoses. Urgent operative intervention was undertaken in each case with good results and no long-term morbidity. The risk of intestinal strangulation in the late-presenting CDH patient warrants emergent surgical management, which should be rewarded by uniform survival with few complications. Although preoperative stabilization may decrease the severity of pulmonary vasospasm in the newborn with respiratory failure, delay may increase the risk of bowel infarction in the older child presenting with gastrointestinal symptoms.

Clinical spectrum of paraesophageal herniation

Paraesophageal herniation is a potentially devastating condition of the gastroesophageal hiatus commonly manifesting in patients of advanced age with other significant medical problems. Surgical treatment is generally indicated to avoid catastrophe related to gastric volvulus. The operative approach utilized should be individualized to the patient's pathophysiologic condition rather than attempting to apply a single repair for all patients with this heterogeneous clinical problem.

Surgical results of intrathoracic gastric volvulus complicating hiatal hernia

From 1981 to 1988, 138 patients with hiatal hernia were treated surgically at our centre. Twenty-one (mean age 76.6 years, 17 women, four men) had an associated intrathoracic gastric volvulus. Eleven patients (mean age 73.2 years), of whom eight were asymptomatic, had an elective procedure. Ten patients (mean age 80.3 years) had emergency surgery, six for acute complications of the volvulus (five cases of strangulation and one of perforated ulcer) and four because of other, unrelated causes of acute abdomen. There were four deaths after operation, all in the emergency surgery group. Four other patients had significant morbidity, all in the emergency group. In the elective cases, all hernias were easily reduced. In one emergency case a gastrotomy was necessary for decompression, and in another gastrectomy was necessary because of gastric gangrene. Our results indicate the need for elective intervention when intrathoracic gastric volvulus is first diagnosed.

Diaphragmatic hiatal hernias. Recognizing and treating the major types

The pathophysiology and treatment of herniations through the esophageal hiatus remain controversial. For the majority of patients with a sliding hiatal hernia, medical treatment is preferred. Antireflux surgical techniques are reserved for those who fail medical treatment or have specific complications. A paraesophageal hernia may be life-threatening and requires surgical correction when diagnosed. Definitive surgical treatment consists of reduction of the hernia, excision of the sac, and partial closure of the widened hiatus anterior to the esophagogastric junction. Temporary gastrostomy is also advisable. A few patients have mixtures of the two types of hernia, and only those with incompetence of the lower esophageal sphincter require an antireflux procedure.
