The durability of laparoscopic Nissen fundoplication: 11-year outcomes.

Laparoscopic Nissen fundoplication (LNF) has become the most commonly performed antireflux procedure since its introduction in 1991. There are few studies with greater than 5-year outcomes. Herein we report a series of 312 consecutive patients who underwent primary LNF before 1996. Follow-up of more than 6 years was available in 166 patients, and the mean follow-up was 11 years (median 11.1 years, range 6.1-13.3 years). Prospective data collection included preoperative and current symptom scores (scale 0 = none to 3 = severe), as well as the level of patient satisfaction and use of antireflux medications. Total symptom score for each patient was summed from seven symptoms for a maximum value of 21. Heartburn and regurgitation were the most improved symptoms; however, all symptoms were significantly improved (P < 0.01). The total symptom score at follow-up was 2.6 down from 7.5 at baseline, with a mean difference of -4.9 (range -12 to 3). The percentage of patients stating they would have the procedure again was 93.3%, and 70% were off daily antireflux medications. Outcomes at a mean of 11 years after LNF are excellent, and the majority of patients had their symptoms resolved or significantly improved and are satisfied with their results.

Delayed gastric emptying in patients undergoing antireflux surgery: analysis of a treatment algorithm.

PURPOSE: Controversy remains about the treatment of patients with mild delayed gastric emptying (90 min < emptying half-time [T(1/2)] < 180 min) who undergo antireflux surgery. This retrospective, nonrandomized study reviewed the records of patients treated from January 1996 through October 2003, during which time we applied two treatment algorithms for patients with mild delayed gastric emptying. The goal of this study was to determine whether the most recent treatment algorithm was effective in reducing the need for a concomitant gastric drainage procedure, pyloroplasty. MATERIALS AND METHODS: Eighteen patients with mild delayed gastric emptying underwent antireflux surgery plus pyloroplasty (group A) before 2001, and 13 patients with mild delayed gastric emptying underwent antireflux surgery plus gastric decompression with percutaneous endoscopic gastrostomy placement (group B) starting in 2001. We reviewed indications for the procedure, complications, and outcomes. Primary outcome measures for this study were recurrence of gastroparesis symptoms and need for pyloroplasty. RESULTS: The average T(1/2) was similar for both groups A and B: 129 min and 123 min, respectively. Eleven of 13 patients (85%) in group B experienced resolution of gastroparesis symptoms, improved gastric emptying times, or both; only 1 patient (8%) underwent subsequent pyloroplasty for treatment failure. Only one serious percutaneous endoscopic gastrostomy-related event occurred (tube migration), and no patients died. Significantly fewer patients in group B required total pyloroplasty (8% vs. 56% in group A; P < 0.008), and significantly fewer required pyloroplasty for symptomatic control (15% vs. 56% in group A; P < 0.03). CONCLUSION: A treatment algorithm incorporating percutaneous endoscopic gastrostomy tube placement at the time of antireflux surgery for gastric decompression successfully managed antireflux surgery patients with mild delayed gastric emptying. This approach allows for a more selective use of pyloroplasty.

Disparity between symptomatic and physiologic outcomes following esophageal lengthening procedures for antireflux surgery.

Although esophageal lengthening procedures (Collis gastroplasty) have been recommended as an adjunct to antireflux surgery in patients with shortened esophagus, there are few data on physiologic outcomes in these patients. This study details the long-term outcomes in patients who underwent antireflux surgery with Collis gastroplasty. All patients undergoing esophagogastric fundoplication (EGF) with a Collis gastroplasty for the management of gastroesophageal reflux disease or paraesophageal hernia were identified from a prospectively maintained database. Symptom questionnaires were used during follow-up to assess symptomatic outcomes. Barium esophogram, upper endoscopy with biopsy, and catheterless esophageal acid monitoring (BRAVO system) were recommended for all patients. Patients with abnormal results of physiologic studies underwent further treatment based on a standardized algorithm. Between 1996 and 2002, a total of 68 patients underwent EGF with Collis gastroplasty. Twenty-seven (40%) had a large paraesophageal hernia, and 20 (30%) had undergone a prior EGF. Fifty-six (82%) of the procedures were performed laparoscopically. Mean follow-up time was 30 months, with 10 (15%) patients lost to latest follow-up. Symptomatic outcome data were available for 85% of patients, with significant improvements reported for heartburn (86%), chest pain (90%), dysphagia (89%), and regurgitation (91%). Most patients (84%) were off medications. Physiologic data were completed in 37% of the patients. Of those undergoing physiologic follow-up studies, 17% had recurrent hiatal hernia, and 80% had endoscopically identified esophagitis and pathologic esophageal acid exposure on pH testing. Despite this, 65% of the patients with objectively identified abnormalities reported significant symptomatic improvement compared to their preoperative symptoms. Two patients developed changes associated with Barrett's esophagus that were not present preoperatively. Distal esophageal injury can persist after EGF with Collis gastroplasty, despite significant symptomatic improvements. Appropriate follow-up in these patients requires objective surveillance, which should eventuate in further treatment if esophageal acid is not completely controlled. Although the Collis gastroplasty is conceptually appealing, these results call into question the liberal application of this technique during EGF.

Pregnancy and delivery after antireflux surgery.

BACKGROUND: Concerns have been raised that subsequent pregnancy after antireflux surgery (ARS) may predispose to wrap disruption or herniation and adversely affect outcomes. Some surgeons withhold ARS in women of childbearing age for fear of this, but outcomes in this population have not been reported. METHODS: All childbearing-age women who underwent ARS for gastroesophageal reflux disease (GERD) between January 1991 and July 2000 were asked to complete a detailed questionnaire. Patients with subsequent pregnancies (SP) after ARS were compared with patients without subsequent pregnancies (NP). RESULTS: Ninety-five of the 118 patients (81%) completed the questionnaire at a mean follow-up of 4.9 years. Fifteen patients had 19 subsequent pregnancies after undergoing ARS, and retching and/or vomiting were reported during 13 of the pregnancies (69%). Preoperative incidence of complicated-GERD including strictures (11% vs. 20%), Barrett's esophagus (19% vs. 13%), esophagitis (36% vs. 33%), and ulceration (4% vs. 0%)-were similar between the nonpregnant and pregnant groups. Incidence of postoperative moderate to severe esophageal (7% vs. 8%) and extraesophageal symptoms (0% vs. 6%) were similar between the SP and NP groups. Postoperative prevalence of antisecretory medications was similar in SP and NP groups (13% and 23%, respectively). The incidence of fundoplications redone did not reach statistical difference between the NP (11%) and SP (0%) groups. Long-term outcomes and failure rates were similar in both groups, except the SP group reported greater overall satisfaction with ARS. CONCLUSIONS: Women of childbearing age have a high incidence of complicated GERD, which may contribute to higher-than-expected rates of symptomatic and anatomic fundoplication failures than first-time ARS. Subsequent pregnancies do not adversely affect outcomes after ARS.

Endoluminal full-thickness plication and radiofrequency treatments for GERD: an outcomes comparison.

HYPOTHESIS: Endoluminal therapies have emerged as adjuncts for the treatment of gastroesophageal reflux disease (GERD) in select patients. OBJECTIVE: To compare the effectiveness of endoscopic full-thickness plication and endoscopic radiofrequency treatments for patients with GERD. PATIENTS: A total of 126 patients who underwent either endoscopic full-thickness plication (FTP) of the gastric cardia or endoscopic radiofrequency (RF) treatment of the esophagogastric junction during a 4-year period were included (68 underwent RF and 58 underwent FTP). INTERVENTIONS: Follow-up data was obtained for 51% of patients (mean follow-up, 6 months). MAIN OUTCOME MEASURES: Comparison of medication use, symptom scores, and pH values at baseline and follow-up. RESULTS: In the RF group, patients with moderate to severe heartburn decreased from 55% to 22% (P < .01), and proton pump inhibitor (PPI) use decreased from 84% to 50% (P = .01). Decreases were also seen for dysphagia, voice symptoms, and cough. Percentage of time the pH was less than 4 was unchanged. In the FTP group, patients with moderate to severe heartburn decreased from 53% to 43% (P = .3), and PPI use decreased from 95% to 43% (P = .01). Percentage of time the pH was less than 4 decreased from 10.0% to 6.1% (P = .05). Decreases were also seen for regurgitation, voice symptoms, and dysphagia. There was no change in scores for chest pain or asthma in either group. CONCLUSIONS: For patients with GERD, RF and FTP both resulted in a decrease in both PPI use and in scores for voice symptoms and dysphagia. In addition, RF resulted in decreased heartburn and cough, while FTP resulted in the most dramatic reduction in regurgitation. Our experience indicates that both procedures are effective, providing symptomatic relief and reduction in PPI use. For patients whose chief complaint is regurgitation, FTP may be the preferred procedure.

Endoscopic therapy for achalasia before Heller myotomy results in worse outcomes than heller myotomy alone.

OBJECTIVE: Heller myotomy has been shown to be an effective primary treatment of achalasia. However, many physicians treating patients with achalasia continue to offer endoscopic therapies before recommending operative myotomy. Herein we report outcomes in 209 patients undergoing Heller myotomy with the majority (74%) undergoing myotomy as secondary treatment of achalasia. METHODS: Data on all patients undergoing operative management of achalasia are collected prospectively. Over a 9-year period (1994-2003), 209 patients underwent Heller myotomy for achalasia. Of these, 154 had undergone either Botox injection and/or pneumatic dilation preoperatively. Preoperative, operative, and long-term outcome data were analyzed. Statistical analysis was performed with multiple chi and Mann-Whitney U analyses, as well as ANOVA. RESULTS: Among the 209 patients undergoing Heller myotomy for achalasia, 154 received endoscopic therapy before being referred for surgery (100 dilation only, 33 Botox only, 21 both). The groups were matched for preoperative demographics and symptom scores for dysphagia, regurgitation, and chest pain. Intraoperative complications were more common in the endoscopically treated group with GI perforations being the most common complication (9.7% versus 3.6%). Postoperative complications, primarily severe dysphagia, and pulmonary complications were more common after endoscopic treatment (10.4% versus 5.4%). Failure of myotomy as defined by persistent or recurrent severe symptoms, or need for additionally therapy including redo myotomy or esophagectomy was higher in the endoscopically treated group (19.5% versus 10.1%). CONCLUSION: Use of preoperative endoscopic therapy remains common and has resulted in more intraoperative complications, primarily perforation, more postoperative complications, and a higher rate of failure than when no preoperative therapy was used. Endoscopic therapy for achalasia should not be used unless patients are not candidates for surgery.
