Proliferative and anti-apoptotic activity of esophageal mucosa in gastroesophageal reflux disease is not affected by fundoplication: a 4-year follow-up study.

BACKGROUND: The role of fundoplication in the prevention of esophageal adenocarcinoma is controversial. Development of cancer is associated with proliferation and anti-apoptosis, for which little data exist regarding their response to fundoplication. METHODS: Ki-67 and Bcl-2 expression was assessed in the esophagogastric junction (EGJ) and the distal and proximal esophagus of 20 patients with gastroesophageal reflux disease (GERD) treated by fundoplication and in 7 controls. Endoscopy was performed preoperatively and 6 (20 patients) and 48 months (16 patients) postoperatively. RESULTS: There were positive correlations between Ki-67 and Bcl-2 levels in the EGJ (p > 0.001) and in the distal (p = 0.001) and proximal esophagus (p = 0.013). Compared to the preoperative level, Ki-67 expression was elevated in the distal (p = 0.012) and proximal (p = 0.007) esophagus at 48 months. In addition, compared to control values, Ki-67 expression was lower at the 6-month follow-up in the EGJ (p = 0.037) and the proximal esophagus (p = 0.003), and higher at the 48-month follow-up in the distal esophagus (p = 0.002). Compared to control values, Bcl-2 was lower at 6 months in the EGJ (p = 0.038). CONCLUSIONS: Proliferative activity after fundoplication increased in the long term in the distal esophagus despite a normal fundic wrap and healing of GERD.

Clinical significance of esophageal histologic findings after antireflux surgery.

HYPOTHESIS: Only limited and controversial information exists regarding the histologic effect of successful antireflux surgery on esophageal mucosa and its clinical significance. DESIGN AND SETTINGS: A randomized, blinded follow-up study conducted in a university hospital between January 1, 1992, and December 31, 1997, with a mean follow-up of 8 months. PATIENTS: Forty patients with severe symptomatic gastroesophageal reflux disease (24 men and 16 women; mean age, 50 years). MAIN OUTCOME MEASURES: Microscopic signs and severity of esophagitis analyzed by 2 blinded histopathologists. RESULTS: Histopathologist 1 interpreted 22 (69%) of 32 postoperative biopsy specimens as normal; 7 (22%), as showing mild changes; 1 (3%), moderate changes; and 2 (6%), severe changes of reflux esophagitis. Histopathologist 2 interpreted 25 (78%) of 32 postoperative biopsy specimens as normal (P =.001); 1 (3%), as showing mild changes (P =.003); 4 (13%), moderate changes; and 2 (6%), severe changes. Between histopathologist 1 (90.6%) and histopathologist 2 (81%), the absence of esophageal mucosal inflammation correlated best with normalized pH monitoring. CONCLUSIONS: These findings suggest that, if other findings such as those from fundic wrap at endoscopy and 24-hour pH monitoring are normal, the clinical significance of routine esophageal histologic examination after successful fundoplication is limited.

Fatal and life-threatening complications in antireflux surgery: analysis of 5,502 operations.

BACKGROUND: There have been few comprehensive studies relating to the life-threatening or fatal complications of antireflux surgery. METHODS: Some 5502 antireflux operations were performed in Finland between January 1987 and January 1996 (population approximately 5 million); 3993 procedures (72.6 per cent) were open fundoplications, 1162 (21.1 per cent) laparoscopic fundoplications and 347 (6.3 per cent) other anti-reflux procedures. RESULTS: There were 43 fatal or life-threatening complications (prevalence 0.8 per cent). Twenty-two followed primary open fundoplication (prevalence 0.6 per cent), 15 laparoscopic fundoplication (prevalence 1.3 per cent) (P < 0.05), one refundoplication and five other antireflux procedures. The overall mortality rate was 0.3 per cent. Nine patients (0.2 per cent) died after open fundoplication, one (0.1 per cent) following laparoscopic fundoplication (P = 0.43), one following refundoplication and four after other antireflux procedures. Laparoscopic fundoplication was followed by 14 non-fatal life-threatening complications (prevalence 1.2 per cent), open fundoplication by 13 (prevalence 0.3 per cent) (P < 0.01) and other antireflux procedures by one life-threatening complication (0.3 per cent). CONCLUSION: Laparoscopic fundoplication was associated with more life-threatening complications than open fundoplication. This may compromise the advantages of the laparoscopic technique.

The long term results of open antireflux surgery in a community-based health care center.

OBJECTIVE: There is no previous study concerning long term results of open Nissen fundoplication performed by general surgeons in a nonspecialized unit. METHODS: Of 45 consecutive patients in a general provincial center, 39 were available for follow-up after a mean period of 78 months. All patients were interviewed using a standard questionnaire, and 35 of them consented to undergo endoscopy. RESULTS: Of the patients, 85% had no or only mild reflux symptoms. The figures for dysphagia, flatulence, and bloating were 31%, 67%, and 46%, respectively. Endoscopy showed defective fundic wrap in 37% of the patients and erosive esophagitis in 29%. Five patients (13%) with recurrent esophagitis were referred for H2-blocker or omeprazole medication, and five others (13%) were scheduled for repeat antireflux surgery. CONCLUSIONS: The results were somewhat worse in regard to prevalence of defective fundic wrap and recurrent esophagitis than in other reports, which were from specialized units.

Gastroesophageal reflux disease as a cause of death: analysis of fatal cases under conservative treatment.

BACKGROUND: Treatment of gastroesophageal reflux disease (GERD) with modern acid-suppressive agents is supposed to be effective and safe. However, there have been only a few studies on the mortality in GERD today. In the 1960s the mortality was 0.10-0.17/100,000 per year. METHODS: From 1990 to 1995, according to Statistics Finland, 78 official death certificates were issued in which GERD was stated to have been the immediate or a primary cause of death. RESULTS: On completion of analysis data on 52 patients were included in the study. The annual death rate was 0.20/100,000. The causes were hemorrhagic reflux esophagitis in 51.9%, aspiration pneumonia in 34.6%, perforation of esophageal ulcer in 9.6%, and spontaneous esophageal rupture with reflux esophagitis in 3.9%. Thirty-eight patients had been treated with omeprazole or an H2 antagonist, and 44 patients (85%) had severe concomitant disease. CONCLUSION: The mortality in conservatively treated GERD has not decreased. Patients with mental disorder, heart disease, or alcoholism constitute the group in which risk of death from conservatively treated GERD is likely to be greatest.

Functional outcome after laparoscopic or open Nissen fundoplication: a follow-up study.

OBJECTIVE: To compare the results of open and laparoscopic fundoplication. DESIGN: Nonrandomized controlled study with a 3-year follow-up. PATIENTS AND METHODS: Fifty-seven consecutive patients with erosive reflux esophagitis underwent laparoscopic (30 patients) or open (27 patients) fundoplication. INTERVENTIONS: Interview by an independent person. In addition, 52 patients (91%) underwent postoperative endoscopy, and 38 patients (67%) underwent esophageal 24-hour pH recording. RESULTS: Temporary dysphagia was reported by 20 patients (67%) after laparoscopic and by 11 (41%) after open fundoplication (P = .05). There were no differences between groups concerning incidence of persistent dysphagia (20% vs 18%, respectively) and mild to no reflux symptoms (97% vs 100%, respectively). In addition, bloating (50% vs 63%, respectively) and increased flatus (77% vs 78%, respectively) were equally common. Visual analog scale scores for dysphagia, bloating, and increased flatus were 0.6, 2.4, and 4.3, respectively, in the laparoscopic and 0.6, 3.5, and 3.4, respectively, in the open groups. Normal belching ability was reported by 12 patients (40%) after laparoscopic and by 20 (74%) after open fundoplication (P = .01). Visick grade 1 or 2 was reported by 21 patients (70%) after laparoscopic and by 24 (89%) after open fundoplication (P = .08). Defective fundic wrap was detected in 4 patients (13%) in the laparoscopic and in none in the open group. In addition, abnormal results of 24-hour pH recording were found in 4 patients (22%) after laparoscopic and in 2 (10.5%) after open fundoplication. CONCLUSION: From a functional point of view, both techniques were equally effective except concerning belching ability and temporary dysphagia.
