Laparoscopic management of hiatal hernia and gastroesophageal reflux

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

Purpose

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

Methods

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

Results

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

Conclusions

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

Impact of laparoscopic Nissen fundoplication on non-complicated Barrett's esophagus

BACKGROUND/AIM

Laparoscopic fundoplication can alter the natural course of Barrett's esophagus (BE). This study was undertaken to assess this role in patients with non-complicated BE.

MATERIALS AND METHODS

From October 2004 to October 2009, 43 patients with BE (32 men and 11 women) underwent laparoscopic Nissen fundoplication surgery in the Department of Surgery at Minia University Hospital. The median age of these patients was 46 years (range: 22-68 years). Patients with high-grade dysplasia, invasive cancer, or previous antireflux surgery were excluded. All 43 patients had gastroesophageal reflux symptoms. Heartburn was present in all patients, regurgitation in 41 (95.3%), dysphagia in 8 (18.6%), retrosternal pain in 30 (69.8%), upper gastrointestinal hemorrhage in 6 (13.9%), and respiratory symptoms in 19 (44.2%). Nissen fundoplication was performed in all patients. Thirty-four patients (79.1%) had concomitant hiatal hernia and nine patients (20.9%) had low-grade dysplasia.

RESULTS

The median follow-up period was 25.6 months. There was significant improvement of symptoms after surgery (P<0.05). Eight (18.6%) of those with short-segment BE had total regression and four (9.3%) of those with long-segment BE had a decrease in total length. Among the nine patients with preoperative low-grade dysplasia, dysplasia disappeared in seven, remained unchanged in one, and progressed to in situ adenocarcinoma in one patient.

CONCLUSIONS

laparoscopic fundoplication succeeded in controlling symptoms but had unpredictable effect on dysplasia and regression of BE. Laparoscopic fundoplication does not eliminate the risk of developing esophageal adenocarcinoma and therefore, endoscopic follow-up should be continued in these patients.

Collagen type I:III ratio of the gastroesophageal junction in patients with paraesophageal hernias

BACKGROUND

The purpose of this study was to examine the biological environment of the esophageal hiatus through analysis of the collagen content within the gastrohepatic ligament (GHL), gastrophrenic ligament (GPL), and phrenoesophageal ligament (PEL) in patients with type I hiatal hernias (HH) and type III paraesophageal hernias (PEH).

METHODS

A control group (N=10) and patients with type I HH (N=10) and type III PEH (N=10) were included in the analysis. Specimens of the GHL, PEL, and GPL were collected intraoperatively. Slides stained with sirius red/fast green were created and ten photos at 400×magnification were taken of each specimen. Axiovision 4.7 (Zeiss) photo analysis software was employed for quantification of collagen I (red) and III (green) by calculating color area (μm2). Statistical significance (p<0.05) was determined using a one-way ANOVA and Fisher's LSD post-test.

RESULTS

Cross-polarization microscopy revealed that the collagen I content was similar in the three study groups for the GHL, greater in the type III PEH group and in the control group compared to the type I HH group for the PEL, and greater in the type III PEH group compared to control group for the GPL. Collagen III quantity was greater in the control group than in the type I HH group for each ligament, and greater in the GHL and PEL when compared to the type III PEH group. Type III PEH patients had greater collagen III quantity than did type I HH patients for each ligament. Collagen type I:III ratio of the GHL was greater in both hernia groups compared to the control group. Type III PEH patients contained a higher I:III ratio than both the control and type I HH groups with respect to the PEL. There was no difference in the ratio with evaluation of the GPL for the three groups.

CONCLUSION

Evaluation of the esophageal hiatus revealed that patients with PEH have a different biological environment with regard to collagen content compared to control patients. The collagen I:III ratio of the study groups was equal to or greater than the control group. Collagen deficiency in the GE junction supporting ligaments does not appear to be an etiology of PEH formation.

Antireflux transoral incisionless fundoplication using EsophyX: 12-month results of a prospective multicenter study

Background

A novel transoral incisionless fundoplication (TIF) procedure using the EsophyX system with SerosaFuse fasteners was designed to reconstruct a full-thickness valve at the gastroesophageal junction through tailored delivery of multiple fasteners during a single-device insertion. The safety and efficacy of TIF for treating gastroesophageal reflux disease (GERD) were evaluated in a prospective multicenter trial.

Methods

Patients (n = 86) with chronic GERD treated with proton pump inhibitors (PPIs) were enrolled. Exclusion criteria included an irreducible hiatal hernia > 2 cm.

Results

The TIF procedure (n = 84) reduced all hiatal hernias (n = 49) and constructed valves measuring 4 cm (2–6 cm) and 230° (160°–300°). Serious adverse events consisted of two esophageal perforations upon device insertion and one case of postoperative intraluminal bleeding. Other adverse events were mild and transient. At 12 months, aggregate (n = 79) and stratified Hill grade I tight (n = 21) results showed 73% and 86% of patients with ≥50% improvement in GERD health-related quality of life (HRQL) scores, 85% discontinuation of daily PPI use, and 81% complete cessation of PPIs; 37% and 48% normalization of esophageal acid exposure; 60% and 89% hiatal hernia reduction; and 62% and 80% esophagitis reduction, respectively. More than 50% of patients with Hill grade I tight valves had a normalized cardia circumference. Resting pressure of the lower esophageal sphincter (LES) was improved significantly (p < 0.001), by 53%. EsophyX-TIF cured GERD in 56% of patients based on their symptom reduction and PPI discontinuation.

Conclusion

The 12-month results showed that EsophyX-TIF was safe and effective in improving quality of life and for reducing symptoms, PPI use, hiatal hernia, and esophagitis, as well as increasing the LES resting pressure and normalizing esophageal pH and cardia circumference in chronic GERD patients.

Laparoscopic mesh-augmented hiatoplasty as a treatment of gastroesophageal reflux disease and hiatal hernias-preliminary clinical and functional results of a prospective case series

BACKGROUND

Because fundoplication-related side effects are frequent, we evaluated laparoscopic mesh-augemented hiatoplasty (LMAH) as a potential treatment option for gastroesophageal reflux disease and/or symptomatic hiatal herania. LMAH aims to prevent reflux solely by mesh-reinforced narrowing of the hiatus and lengthening of the intra-abdominal esophagus.

METHODS

Twenty-two consecutive patients with LMAH were evaluated prospectively using a modified Gastrointestinal Symptom Rating Scale questionnaire, pH measurement, manometry, and endoscopy. Follow-up was scheduled at 3 and 12 months after surgery.

RESULTS

Total reflux decreased from 16.3% before surgery to 3.5% 3 months after surgery (P = .001). The reflux score decreased from 3.8 before surgery to 2.1 1 year after surgery (P = .001). The respective values of the indigestion score were 3.4 and 2.0 (P < .001). After surgery, all patients were able to belch. Vomiting was impossible only for 2 patients, and 90% of patients assessed their results as good to excellent.

CONCLUSIONS

LMAH seems to be feasible, safe, and has no significant side effects.

Laparoscopic mesh repair antireflux surgery for treatment of large hiatal hernia

One of the most frequently occurring anatomic failures after laparoscopic fundoplication is migration of the wrap into the chest, with or without disruption. This so-called 'slipped' Nissen fundoplication may be the result of inadequate closure of the diaphragmatic crura or rupture of the sutures or disruption of the muscle fibers approached. From January 2000 to December 2002, a total of seven patients (four male) with a mean age of 56 years (range 22-72 years), were considered for laparoscopic antireflux procedure using DACRON mash to reinforce the crural hiatal closure. The patients were operated under general anesthesia; laparoscopy was performed by classical approach with five trocars. The mean operative time was 120 minutes (range 40-240 min). There were no deaths. The average of postoperative hospital stay was 3.5 days (range, 3-5). Patients returned to normal activities usually on postoperative day 10 (range, 7-15). The follow-up time was at least 2 years. There was only one late complication related to the use of DACRON mesh at the hiatus, due to migration of the mesh into the esophageal lumen causing disphagia. In conclusion the mesh repair antireflux surgery is a good alternative for closing the diaphragmatic defect in large hiatal hernias or to correct this problem in case of recurrence or Barrett's esophagus.

Evidence-based appraisal of antireflux fundoplication

OBJECTIVE

To highlight the current available evidence in antireflux surgery through a systematic review of randomized controlled trials (RCTs).

SUMMARY BACKGROUND DATA

Laparoscopic fundoplication is currently suggested as the gold standard for the surgical treatment of gastroesophageal reflux disease, but many controversies are still open concerning the influence of some technical details on its results.

METHODS

Papers related to RCTs identified via a systematic literature search were evaluated according to standard criteria. Data regarding the patient sample, study methods, and outcomes were abstracted and summarized across studies. Defined outcomes were examined for 41 papers published from 1974 to 2002 related to 25 RCTs. A meta-analysis was performed pooling the results as odds ratios (OR), rate differences (RD), and number needed to treat (NNT). Data given as mean and/or median values were pooled as a mean +/- SD (SD).

RESULTS

No perioperative deaths were found in any of the RCTs. Immediate results showed a significantly lower operative morbidity rate (10.3% versus 26.7%, OR 0.33, RD -12%, NNT 8), shorter postoperative stay (3.1 versus 5.2 days, P = 0.03), and shorter sick leave (20.1 versus 35.8 days, P = 0.03) for laparoscopic versus open fundoplication. No significant differences were found regarding the incidence of recurrence, dysphagia, bloating, and reoperation for failure at midterm follow-up. No significant differences in operative morbidity (13.1% versus 9.4%) and in operative time (90.2 versus 84.2 minutes) were found in partial versus total fundoplication. A significantly lower incidence of reoperation for failure (1.6% versus 9.6%, OR 0.21, RD -7%, NNT 14) was found after partial fundoplication, with no significant differences regarding the incidence of recurrence and/or dysphagia. Routine division of short gastric vessels during total fundoplication showed no significant advantages regarding the incidence of postoperative dysphagia and recurrence when compared with no division. The use of ultrasonic scalpel compared with clips or bipolar cautery for the division of short gastric vessels showed no significant effect on operative time, postoperative complications, and costs.

CONCLUSIONS

Laparoscopic antireflux surgery is at least as safe and as effective as its open counterpart, with reduced morbidity, shortened postoperative stay, and sick leave. Partial fundoplication significantly reduces the risk of reoperations for failure over total fundoplication. Routine versus no division of short gastric vessels showed no significant advantages. A word of caution is needed when implementing these results derived from RCTs performed in specialized centers into everyday clinical practice, where experience and skills may be suboptimal.

Efficacy of laparoscopic antireflux surgery in patients with Barrett's esophagus

BACKGROUND

Laparoscopic antireflux surgery (LARS) corrects significant physiologic and anatomic abnormalities in patients with gastroesophageal reflux disease (GERD); however, debate exists whether LARS prevents recurrent symptoms and malignant transformation in patients with Barrett's esophagus (BE). This study compared clinical outcomes after LARS in patients with and without BE.

METHODS

From 1994 to 2001, 448 patients who underwent LARS were studied. Of these, 68 (15%) had preoperative evidence of BE with low-grade dysplasia in 3 (4%), and 380 (85%) were without BE. Mean postoperative follow-up was more than 30 months in each group.

RESULTS

After LARS, there was equivalent reduction in acid reduction medication use and typical GERD symptoms in both groups. Anatomic failures developed in 12% of patients with BE and in 5% of those without BE (P = 0.05). Upper endoscopy with biopsies was obtained in 50 of 68 patients (74%) with BE at 37 +/- 22 months postoperatively. Intestinal metaplasia was no longer present in 7 of 50 (14%) BE patients, and low-grade dysplasia regressed to nondysplastic Barrett's in 2 of 3 patients. New low-grade dysplasia developed in 1 BE patient (2%) at postoperative endoscopic surveillance. No BE patients developed high-grade dysplasia or adenocarcinoma.

CONCLUSIONS

After LARS, patients with BE have symptomatic relief and reduction in medication use equivalent to non-BE patients. Regression of intestinal metaplasia and the absence of progression to high-grade dysplasia or adenocarcinoma suggest that LARS is an effective approach for the management of patients with Barrett's esophagus. The higher failure rate of LARS in BE is of concern and mandates ongoing follow-up of these patients.

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.

Short esophagus: literature incidence

There are controversies regarding existence and incidence of short esophagus. The authors reviewed the literature incidence of short esophagus among operated patients due to gastroesophageal reflux disease in the last 3 years. The overall incidence of short esophagus was 1.53%. The proposed risk factors (paraesophageal hernia, Barrett's esophagus, reoperation, esophageal strictures and access route) do have a higher incidence of short esophagus, with the exception of the Barrett's esophagus. Although several biases can be associated with the review, the authors identified the short esophagus incidence in the literature.

Clinical outcomes after laparoscopic antireflux surgery in patients with and without preoperative endoscopic esophagitis

A wide spectrum of endoscopic findings exists in patients with gastroesophageal reflux disease (GERD). This study compared clinical outcomes after laparoscopic antireflux surgery (LARS) in patients who had GERD with and without preoperative endoscopic esophagitis. From 1992 to 2001, a total of 414 patients who underwent LARS with 6 months or more of follow-up were prospectively entered into a database. Among these patients, 84 (20%) had no endoscopic evidence of esophagitis on preoperative endoscopy (group 1), whereas 330 (80%) did have esophagitis (group 2). Perioperative outcomes, GERD symptom relief, and the use of acid-reducing medication were assessed. Preoperative DeMeester scores in groups 1 and 2 were 44 +/- 29 and 61 +/- 62 (P < 0.05) and mean esophageal peristaltic amplitude was 86 +/- 32 mm Hg vs. 60 +/- 42 mm Hg, respectively (P < 0.05). Although procedure time was significantly shorter in group 1, other perioperative outcomes were similar. At postoperative follow-up, the use of proton pump inhibitors was reduced in both groups (86% to < or =14%). With the exception of postoperative dysphagia, there was no difference in GERD symptom relief between groups 1 and 2. The presence or absence of preoperative esophagitis has minimal effect on favorable symptomatic outcomes after LARS. Thus LARS is an effective treatment option for patients, irrespective of endoscopic evidence of esophagitis, leading to excellent symptom relief and a marked reduction in the use of proton pump inhibitors.

Laparoscopic repair of large paraesophageal hiatal hernia

BACKGROUND

The objective of this study was to analyze our initial results after laparoscopic repair of large paraesophageal hiatal hernias.

METHODS

Between October 1997 and May 2000, 37 patients (23 women, 14 men) underwent laparoscopic repair of a large type II (pure paraesophageal) or type III (combined sliding and paraesophageal) hiatal hernia with more than 50% of the stomach herniated into the chest. Median age was 72 years (range 52 to 92 years). Data related to patient demographics, esophageal function, operative techniques, postoperative symptomatology, and complications were analyzed.

RESULTS

Laparoscopic hernia repair and Nissen fundoplication was possible in 35 of 37 patients (95.0%). Median hospitalization was 4 days (range 2 to 20 days). Intraoperative complications occurred in 6 patients (16.2%) and included pneumothorax in 3 patients, splenic injury in 2, and crural tear in 1. Early postoperative complications occurred in 5 patients (13.5%) and included esophageal leak in 2, severe bloating in 2, and a small bowel obstruction in 1. Two patients died within 30 days (5.4%), 1 from delayed splenic bleeding and 1 from adult respiratory distress syndrome secondary to a recurrent strangulated hiatal hernia. Follow-up was complete in 31 patients (94.0%) and ranged from 3 to 34 months (median 15 months). Twenty-seven patients (87.1%) were improved. Four patients (12.9%) required early postoperative dilatation. Recurrent paraesophageal hiatal hernia occurred in 4 patients (12.9%). Functional results were classified as excellent in 17 patients (54.9%), good in 9 (29.0%), fair in 1 (3.2%), and poor in 4 (12.9%).

CONCLUSIONS

Laparoscopic repair of large paraesophageal hiatal hernias is a challenging operation associated with significant morbidity and mortality. More experience, longer follow-up, and further refinement of the operative technique is indicated before it can be recommended as the standard approach.
