Vagotomy, antrectomy, and Roux-en-Y diversion for complex reoperative gastroesophageal reflux disease.
OBJECTIVE: Failure of conventional surgical therapy for treatment of patients with gastroesophageal reflux disease (GERD) taxes the ingenuity of the esophageal surgeon. This study defines the role of vagotomy, antrectomy, and Roux-en-Y diversion coupled, when necessary, with resection of the esophagogastric junction as an alternative to other surgical procedures currently employed for these complicated cases. SUMMARY BACKGROUND DATA: Currently, the operation in question rarely is performed in the United States. Other procedures, such as interposition of short or long segments of intestine and total esophagectomy with gastric pull-up, are preferred. However, surgeons from Scandinavia, Great Britain, and Europe have published widely on the subject, some even preferring its use as a primary procedure in GERD. METHODS: This report reviews the indications and results of the operation in 36 patients who underwent operation between January 1970 and January 1994. Follow-up evaluation was available for review in 33 patients observed from 1 to 20 years postoperatively (average, 6 2/3 years). Of these patients, 32 had undergone 66 previous operative procedures on the distal esophagus and stomach ranging from 1 to 6 per patient. There were no hospital deaths, but complications developed in nine patients (25%); only half of these complications were major. Of patients available for follow-up, 85% were improved by the operation, 24 of the 33 having excellent or good results. CONCLUSIONS: The operation of vagotomy, antrectomy, and Roux-en-Y diversion, embodying the principles of acid suppression and alkaline diversion, has proved to be a successful alternative to other operative procedures currently favored in the United States for the treatment of the complex reoperative patient with GERD.

Oesophagomyotomy for achalasia: a 22-year experience.
To determine the clinical results in achalasia, particularly as regards postoperative gastro-oesophageal reflux, a 22-year personal experience with transthoracic short oesophagomyotomy without an antireflux procedure was analysed. A total of 185 such procedures were performed, of which 179 (97 per cent) were available for analysis. There was an overall improvement rate of 89 per cent over a mean postoperative interval of 9 years. Primary procedures were followed by a 93 per cent rate of improvement. Twenty patients, nine of whom had previously undergone one or more oesophageal operations, were considered as having a poor result. Marked gastro-oesophageal reflux accounted for a poor outcome in nine patients. Although the overall rate of postoperative improvement did not deteriorate significantly with time, the level of improvement did, the proportion of excellent results declining from 54 to 32 per cent (P = 0.02) at 10-20 years after operation. These findings substantiate the view that a short transthoracic oesophagomyotomy without an antireflux procedure provides excellent long-term relief of dysphagia for the patient with oesophageal achalasia and is accompanied by an extremely low risk of serious postoperative gastro-oesophageal reflux.

Staging of carcinoma of the esophagus and cardia: a comparison of different staging criteria.
The third edition [1988] of the Manual for Staging of Cancer of the American Joint Committee on Cancer (AJCC) was developed to permit finer discrimination between stages than was true of the previous edition [1983]. This study was designed to determine whether or not this goal was achieved. Pathologic staging of the specimens removed from 265 patients with carcinoma of the esophagus or cardia undergoing esophagogastrectomy between 1970 and 1988 was performed according to criteria published in the second and third editions and their survival data compared. The new staging criteria of the AJCC provides no better discrimination of stages according to survival than was true of the earlier version, the 5-year survival of stage IIA patients being similar to that of stage I patients (37.5 +/- 6.7% vs. 50.8 +/- 17.7%), and the survival of stage IIB patients being similar to that of stage III patients (16.2 +/- 8.1% vs. 13.6 +/- 3.7%). However, depth of wall penetration and extent of lymph node involvement were reliable independent predictors of survival. We propose a modified version of the Skinner WNM staging plan that provides a modest increase in staging fragmentation.

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.

Endoscopic surveillance of Barrett's esophagus. Does it help?
Patients with Barrett's esophagus are recognized as having a high risk of development of adenocarcinoma. Although endoscopic surveillance of these patients is commonly practiced, its benefits have not been proved. This study was undertaken to examine the effect of endoscopic surveillance on the stage of resected carcinoma arising in Barrett's esophagus and the effect on postoperative survival. Between 1973 and 1991, 77 patients with adenocarcinoma were seen by us, and 19 of them were under endoscopic surveillance. The 19 patients underwent endoscopic biopsies at 1-month to 4-year intervals (median 6 months). All but one patient underwent esophagogastrectomy when severe dysplasia or invasive carcinoma was detected. The stages of the resected carcinomas in the group under surveillance compared with the group not under surveillance were significantly different, 58% of the patients under surveillance having stages 0 and I disease and 21% having stage III disease compared with 17% of the patients not under surveillance having stages 0 and I disease and 47% having stage III disease (p = 0.006). The 5-year actuarial survival of patients undergoing routine surveillance was 62% and of patients not under surveillance, 20% (p = 0.007). Endoscopic surveillance of patients with benign Barrett's esophagus permits detection of carcinoma at an early stage and improves long-term survival after resection for severe dysplasia and invasive carcinoma.

Esophagomyotomy for noncardiac chest pain resulting from diffuse esophageal spasm and related disorders.
Esophagomyotomy was performed in 42 patients with chest pain resulting from diffuse esophageal spasm and related disorders. The procedure used restricted the myotomy to the diseased portion of the esophagus, as demonstrated manometrically. More than half of the patients also required myotomy of the lower esophageal sphincter. Some patients required other surgical procedures. Overall results were excellent; the overall improvement rate was 70% at a median follow up of 5 years, 8 months. Postoperatively, 5 patients had recurrent or persistent pain. Esophagomyotomy is recommended for selected patients with clinically significant chest pain and/or dysphagia.

Selective use of myotomy for treatment of epiphrenic diverticula. Manometric and clinical analysis.
The pathogenesis and treatment of epiphrenic diverticula remain controversial subjects. Most surgeons recommend esophagomyotomy in association with diverticulectomy in every patient. We believe that selective use of myotomy, based on manometry, should be used. From 1960 to 1990, 16 patients underwent surgical treatment for epiphrenic diverticulum at the Lahey Clinic Medical Center, Burlington, Mass. Six patients, three of whom underwent diverticulectomy alone and three who underwent an associated long myotomy, had the lower esophageal sphincter left intact; long-term results were good in all patients. The remaining 10 patients underwent myotomy of the lower esophageal sphincter. Reflux esophagitis developed in two of these patients who had a normal lower esophageal sphincter. Clinical results support the selective use of esophagomyotomy applied to areas of demonstrated dysmotility. A normal lower esophageal sphincter should be left intact to prevent reflux complications.

The Nissen fundoplication.
The most commonly employed antireflux operation is the Nissen fundoplication. However, its origin and subsequent modifications are rarely defined. These aspects of the operation are reviewed in this article as are the results currently obtainable with the modern version of the operative procedure.

Current concepts concerning the nature and treatment of Barrett's esophagus and its complications.
Current concepts regarding the nature and the treatment of Barrett's esophagus and its complications are reviewed. The columnar-lined lower esophagus is being increasingly recognized as an acquired condition caused by gastroesophageal reflux. Many patients are asymptomatic. Barrett's esophagus occurs in about 10% to 15% of patients with reflux esophagitis. The diagnosis depends on endoscopy and biopsy. Complications are common and include ulceration, stricture, dysplasia, and adenocarcinoma. Esophagitis, ulceration, and stricture can usually be treated medically. Surgical approaches are discussed for patients whose condition is refractory to medical therapy. The premalignant nature of Barrett's epithelium is well recognized, and strategies for surveillance and resection are discussed. Survival after resection of adenocarcinoma in Barrett's esophagus is not appreciably different from that of other carcinomas. Surveillance with endoscopy offers the best chance for early detection and cure.

Ten to 20-year clinical results after short esophagomyotomy without an antireflux procedure (modified Heller operation) for esophageal achalasia.
To determine the long-term clinical results after modified esophagomyotomy without an antireflux procedure for esophageal achalasia, the status of all patients undergoing this operation with a minimum follow-up time of 10 years was reviewed; 81 such patients were operated on between January 1970 and January 1981. Thirteen patients were lost to follow-up review permitting clinical evaluation during the past year of 68 patients (84%) observed for a median of 13.6 years. Fifty-nine patients (87%) were improved by operation; 90% of the patients who underwent a primary procedure were improved, whereas only 73% of patients undergoing reoperation benefited. Kaplan-Meier analysis of the results of all 81 patients disclosed an improvement rate of 98.5% at 5 years, 95.6% at 10 years, 85.8% at 15 years, and 67.3% at 20 years. When the level of improvement or lack thereof was analyzed, the percentage of excellent results decreased from 54% to 32% (P = 0.02). The percentage of good results remained the same, whereas fair or poor results together increased from 20% to 37% (P = 0.05). Neither age, sex, esophageal caliber, duration of symptoms, or previous therapy appeared to influence these results. We conclude that limited esophagomyotomy without an antireflux procedure results in persistent long-term improvement for the patient with esophageal achalasia. The level of improvement, however, decreases with the passage of time, presumably because of persistent disease in the body of the esophagus leading to impaired esophageal emptying in some patients and late reflux esophagitis in other patients owing to poor esophageal clearance.

Pulmonary venous infarction.
Pulmonary venous infarction, although rare, can develop in patients with the various pathologic conditions outlined. The triad of cough, dyspnea, and hemoptysis should raise clinical suspicion. The venous phase of pulmonary arteriography is the best way to document pulmonary venous obstruction, although MR imaging may also prove useful in the future. Treatment of patients with pulmonary venous infarction should be determined on the basis of the obstructing pathologic findings. Antibiotic therapy is important, as evidenced by the early experimental experience with this condition. It may be the only treatment available to patients with idiopathic fibrosing mediastinitis. Pulmonary resection, however, can be accomplished when a localized obstructing lesion is identified.

Pulmonary venous infarction secondary to squamous cell carcinoma.
This type of pulmonary venous infarction has not been previously reported, namely: pulmonary vein obstruction from squamous cell carcinoma. Furthermore, this case is unique in that the characteristic pathologic vascular changes observed with pulmonary venous infarction were contrasted with a noninfarcted upper lobe that was removed from the same patient one year later.

Barrett's ulcer: a surgical disease?
Between 1973 and 1990, 285 patients with Barrett's esophagus were treated at the Lahey Clinic. Of these patients, 73 had adenocarcinoma in Barrett's esophagus either when first seen or while under surveillance. Of the remaining 212 patients with benign Barrett's esophagus, 30 had endoscopic evidence of a Barrett's ulcer, for a prevalence of 14%. Initial treatment consisted of aggressive medical therapy, including H2 antagonists and antacids as well as the usual dietary and antireflux measures. In 2 to 4 months, 27 patients underwent repeat endoscopy. Continued endoscopic evaluation in this group totaled 109 patient-years, with a range of 2 months to 13 years (median 2.3 years). Complete healing occurred in 23 of the 27 patients (85%) in 2 to 14 months (median 4 months). Recurrent ulcers developed in seven patients, and these ulcers healed with further medical therapy in five patients. Antireflux procedures were performed in four of six patients with nonhealing Barrett's ulcers, 1 to 1.5 cm in size, and all healed. Two patients refused to have an operation. In our experience, the majority of Barrett's ulcers heal with medical therapy. We reserve surgical intervention for otherwise suitable candidates for operation when no evidence of healing is found within 4 months of medical therapy or for the complications of Barrett's ulcer, namely, perforation, uncontrollable hemorrhage, or malignant degeneration, which were not encountered in this series.

Barrett's esophagus. Prevalence and incidence of adenocarcinoma.
Between January 1973 and January 1989, 241 patients with Barrett's esophagus were treated at the Lahey Clinic Medical Center, Burlington, Mass. Of these patients, 65 presented with adenocarcinoma in Barrett's esophagus for a prevalence rate of 27%. Of 176 patients followed up for a total of 497 patient-years, adenocarcinoma developed in five patients for an incidence of one per 99 patient-years. The development of adenocarcinoma during endoscopic surveillance 1, 2, 2, 4, and 10 years after the initial diagnosis of Barrett's esophagus emphasizes the importance of long-term endoscopic and histologic surveillance. All five patients had severe dysplasia before adenocarcinoma developed. Yearly endoscopic follow-up examination is recommended for all patients with Barrett's esophagus unless mild dysplastic changes are found, in which case surveillance should be increased. Patients with severe dysplasia who are otherwise acceptable candidates for operation should be advised to have esophageal resection.

Barrett's esophagus. A continuing conundrum.
Barrett's esophagus, a condition in which the distal esophagus is lined by columnar epithelium, is almost always caused by gastroesophageal reflux and often occurs in conjunction with a sliding hiatal hernia. Patients are typically white men in their 50s who smoke and drink, and they present with complaints of regurgitation, heartburn, and/or dysphagia. Endoscopic biopsies are required to confirm the diagnosis. Complications, such as stricture, ulcer, dysplasia, and malignant degeneration, occur in many cases. Adenocarcinoma is the most serious complication. Medical treatment, including life-style changes as well as pharmacologic therapy, usually relieves symptoms and heals esophagitis, but when it fails, antireflux surgery is indicated. Patients without evidence of dysplasia should undergo endoscopy yearly; those with mild dysplasia require more frequent surveillance. If biopsies disclose severe dysplasia, esophagogastrectomy should be performed.
