A prospective study of 595 patients treated by the Thoracic Surgical Unit (TSU) at the University College Hospital (UCH), Ibadan between July 1975 and December 1977 was carried out to determine the pattern of thoracic surgical diseases in Nigeria and to prove or disprove the rarity of certain cardiopulmonary diseases in tropical Africa. This review shows that pyogenic infections of the lung and pleura constitute the largest percentage (38.5) of the thoracic surgical diseases in Nigeria. Although pulmonary tuberculosis accounts for only 23.4 percent of our total inpatient load, it constitutes about 60 percent of our outpatient clinic practice. Cardiovascular diseases form 12.9 percent, notably congenital and acquired valvular heart diseases. An interesting finding was the occasional association of pyomyositis with pyogenic pericarditis and empyema thoracis. This triad is being investigated. Chest trauma was the most common thoracic surgical emergency accounting for 9.2 percent of the total thoracic surgical pathology. The most common causes of dysphagia are strictures from corrosive esophagitis, achalasia, and carcinoma of the esophagus. Present experience confirms the rarity of hiatus hernia, reflux esophagitis, atherosclerotic cardiovascular disease, and, perhaps, carcinoma of the lung among Nigerians.

The indication for the non-resecting combination method arises if the presence of genuine ulcer disease is confirmed by complete diagnostic measures (history, roentgenologic examination, endoscopy, secretion analysis and possibly psychic testing). An extended indication exists for erosive gastritis with hypersecretion, for hiatal hernia with reflux esophagitis (Berman's syndrome), for cardiospasm and prophylaxis of hemorrhage. The technique yields permanent curative results if a complete selective proximal vagotomy is combined with a pyloroplasty suitable in form and function. This is also true for duodenal ulcer. In 22% of cases of gastric ulcer, selective vagotomy with antrectomy is necessary.

The treatment of achalasia at the present time is far from being ideal. The results of pneumatic dilatation have not always been impressive and the risk of esophageal perforation is real. Modified Heller operation has succeded in relieving obstructive symptoms in the majority of patients with achalasia. However, the reported incidence of reflux esophagitis following Heller myotomy is four to 37 per cent. In 25 patients with achalasia followed up to 10 years after Heller myotomy, nine patients had symptomatic reflux and three patients developed esophageal strictures. We believe the addition of an anti-reflux operation should be considered in all patients undergoing operation for achalasia and especially those patients with preoperative symptoms of reflux.

From 1978 to 1983, 17 patients had an esophagocardiomyotomy with an added short total fundoplication as an antireflux procedure. Thirteen had achalasia and 4, diffuse esophageal spasm. All patients initially had the usual symptoms of these motor disorders. Early after the operation all became asymptomatic, but over the years of follow-up, symptoms reappeared in 14 of 17 patients, and 5 required reoperation. The distal esophageal transverse diameter showed progressive dilatation from 3.9 cm preoperatively to more than 6 cm after 10 years of evolution. Over the same period, deterioration in the esophageal emptying capacity caused esophageal stasis to increase from 32% to 75%. Manometric changes were significant after the operation: resting pressures in the esophageal body decreased from 10.5 to 4.4 mm Hg (p < 0.001) proximally and from 12.2 to 4.6 mm Hg distally (p < 0.001). Peak contraction pressures became significantly weaker: 38 to 30 mm Hg in the proximal esophagus (p < 0.001) and from 49.2 to 28.1 in the distal esophagus (p < 0.001). Tertiary contractions were unchanged distally, but peristalsis reappeared in more than 30% of all swallows in the proximal half of the esophageal body. The resting pressure gradient in the lower esophageal sphincter area was reduced from 25.5 to 7.4 mm Hg by the operation. This gradient remained stable over 10 years of follow-up. No significant acid exposure was documented in 8 patients undergoing 24-hour pH recordings after their operation. Endoscopy revealed dilatation and retention without evidence of reflux esophagitis damage. Total fundoplication when associated with esophageal myotomy results in improved symptoms in the early postoperative phase.(ABSTRACT TRUNCATED AT 250 WORDS)

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.

Pneumatic dilatation of the cardia is an effective procedure to treat patients suffering from achalasia. Eighty percent of these patients can be expected to have excellent or good results for 6 years after the first dilatation. A repeat dilatation should be performed as soon as the patient has recurrent symptoms, usually every 2 years. Calcium channel blockers (nifedipine and verapamil) or nitrates (isosorbide dinitrate) decrease LES pressure but do little to the clinical symptomatology of patients with achalasia; however such drug therapy may be tried as an adjunct in patients who remain symptomatic after pneumatic dilatations or myotomy. Pneumatic dilatation and surgical myotomy both reduce LES pressure; with pneumatic dilatation, enough residual LES pressure is retained to prevent gastroesophageal reflux. Indeed, reflux esophagitis seems to occur more often after surgery than after forceful dilatations. We think that pneumatic dilatation should be performed as the primary therapy and surgery reserved for the failures of this procedure.

Surgical therapy for achalasia of the esophagus gives good results in only 80-90% of cases. Several reasons could be responsible for this 10-20% failure; the most frequent causes are inadequate cardiomyotomy and reflux esophagitis. We report our experience and our procedure in the management of recurrent achalasia. The most important controversies are also discussed.

Between 1967 and 1989, 60 patients underwent pneumatic dilation of the cardia at our institution. Of these, 33 had not undergone any previous treatment (group 1), whereas 27 presented with recurrent dysphagia after a failure of surgical treatment (group 2). In this series there was no procedure-related mortality and a perforation occurred only in 1 patient who was treated conservatively. The mean follow-up was similar in both groups (44 and 49 months, respectively). The results of pneumatic dilation were either excellent or good in 61% of group 1 patients, and in 76% of group 2 patients. Reflux oesophagitis requiring medical therapy occurred in 1 group 2 patient. We conclude that pneumatic dilation is a safe and relatively effective procedure in patients with achalasia. Patients with a failed Heller myotomy seem to respond better than patients without previous surgery. However, the risk of gastro-oesophageal reflux after pneumatic dilation should not be underestimated.

From 1985 to 1990, 62 patients have undergone pneumatic dilatation with the modified Gruntzig (Levine) dilator in the treatment of achalasia. A single dilatation with a 30-mm balloon dilator was successful in 85% of the patients. Nine patients required additional procedures. One elected for operative surgical repair, and eight patients underwent a second dilatation with a 35-mm balloon dilator. One patient required a third procedure with a 40-mm dilator. Two patients developed dysphagia for solids after pneumatic dilatation, and did not demonstrate delay or obstruction to the passage of technetium on follow up study. We have described this syndrome as dysfunctional dysphagia, and believe that it is related to the rapid ingestion of a food bolus, and is relieved by eating smaller portions at a slower rate. This is to be differentiated from reflux esophagitis and/or stricture secondary to reflux. One patient required bougie dilatation of a stricture, and three other patients were treated with omeprazole, ranitidine, or antacids with relief of reflux symptoms. The safety and efficacy of the procedure of pneumatic dilatation under direct endoscopic control with the modified Gruntzig dilator has been demonstrated in patients from 8 to 93 yr old, and in patients who have had prior Heller myotomy.

Esophageal disease has been reported in 70% to 90% of patients with scleroderma, of whom nearly 50% will have reflux esophagitis. The combined motility disorder of low LES pressure and aperistalsis of the esophageal body makes scleroderma patients especially susceptible to severe gastroesophageal reflux disease (GERD). Symptomatic GERD is a common problem in pregnancy, affecting 30% to 50% of women. Hormonal effects of estrogen and progesterone likely promote GERD by compromising LES function. Fortunately, the problem is usually relieved with delivery of the baby. Although difficult to quantitate, the reflux of both acid and especially alkaline material may be a common sequela of many types of gastric surgery. Medical therapy binding bile salts usually does not bring relief. The Rouxen-Y biliary diversion operation is the best solution for this problem. GERD complicates the treatment of achalasia after 10% of Heller myotomies and 2% of pneumatic dilatations. Nearly 50% of patients with the Zollinger-Ellison syndrome have esophagitis, which may be more difficult to treat than their ulcer disease.
