Heller's myotomy with partial fundoplication

Successful treatment of esophageal achalasia with laparoscopic Heller myotomy and Toupet fundoplication

BACKGROUND

Recently, investigators have reported the use of endoscopic myotomy in the treatment of esophageal achalasia. As with the open operation, considerable disagreement exists regarding the appropriate length of the myotomy and the need for a concomitant antireflux procedure.

METHODS

Patients presenting with symptomatic achalasia between 1993 and 1997 were included in this prospective study. Preoperative studies included barium upper gastrointestinal study, endoscopy, and esophageal manometry. Laparoscopic myotomy was completed in all 20 patients; 18 had concomitant Toupet fundoplication.

RESULTS

Operative times ranged from 95 to 345 minutes (mean 216). Blood loss ranged from 50 to 300 cc (mean 100 cc). There were 7 minor complications (5 mucosal injuries repaired laparoscopically, 1 bile leak and 1 splenic capsular tear). Nine patients began a liquid diet on the first day postoperatively; 19 were tolerating liquids by postoperative day 3. Hospital stay ranged from 2 to 20 days (mean 5). Eighteen patients had complete relief of dysphagia, with less than one reflux episode per month. One individual continues to have mild persistent solid food dysphagia. Another patient initially did well but subsequently developed mild recurrent dysphagia and reflux. One patient required laparoscopic take-down of the wrap because of recurrent dysphagia and now has no problems swallowing, but does complain of mild reflux. Two other patients also have mild reflux, 1 of whom did not undergo fundoplication.

CONCLUSIONS

Laparoscopic Heller myotomy can be performed safely with excellent results in patients with achalasia. Adding a partial fundoplication appears to help control postoperative symptoms of reflux. This procedure should be considered the procedure of choice in patients with symptomatic esophageal achalasia.

Laparoscopic management of achalasia

Cardiomyotomy for achalasia is one of the ideal procedures for the video endoscopic approach. Magnification of the operative field during laparoscopic surgery allows precise division of the muscle fibers with excellent results. The number of reports on cardiomyotomy performed with laparoscopic (and thoracoscopic) access is growing. They all show the same excellent results as for conventional (open) myotomy, with minimal morbidity, short hospital stay, and early return to routine activity.

Laparoscopic esophagomyotomy for achalasia

Results of an ongoing clinical study treating achalasia patients with a transabdominal laparoscopic Heller myotomy and Toupet partial fundoplication are presented. Twelve patients underwent surgery between January 1992 and October 1993. All patients had barium esophagograms, preoperative endoscopy, esophageal manometry, 24-h pH studies, and extensive GI history preoperatively. Surgical complications included two perforations of the mucosa at the gastroesophageal junction repaired laparoscopically. There were no surgical mortalities and the average hospital stay was 39 h. Postoperatively all patients at follow-up had a repeat GI history, esophagogastroscopy, 24-h pH testing, and esophageal manometry. This follow-up showed good-to-excellent relief of dysphagia in all 12 patients with one patient complaining of heartburn documented to be from reflux postoperatively. Manometry showed a mean decrease in the lower esophageal sphincter pressure from 33.4 mmHg preoperatively to 19.3 mmHg postoperatively; 24-hour pH testing showed no significant reflux in the nine patients who had Heller myotomy plus a Toupet fundoplication. However, two of three patients who had Heller myotomy alone demonstrated abnormal 24-h pH testing. One of these patients was symptomatic and was found to have mild esophagitis by biopsy on postoperative endoscopy. These good results have persisted for mean follow-up of 16 months.

The surgical management of motility disorders

Surgical treatment is either the therapy of choice or a facultative procedure in various types of esophageal motility disorders. In achalasia, cardiomyotomy, frequently combined with fundoplasty, achieves good or excellent results in > 80% of cases, and is, therefore, advised in cases when pneumostatic dilatation fails. Diverticulectomy and myotomy of the upper or lower esophageal sphincter are proven procedures to treat cervical and epiphrenic diverticula, leading to good/excellent results or at least an improvement in more than 95%. If, exceptionally, parabronchial diverticula require therapy, they should be excised transthoracically. Cervical myotomy is indicated in cases of cervical achalasia, when sufficient pharyngeal propulsion is preserved. In systemic diseases like scleroderma reflux induced complications may require surgical intervention in medically intractable cases. In these rather few cases, subtotal gastrectomy with a Roux-en-Y anastomosis is advised. In patients suffering from diffuse esophageal spasm or symptomatic "nutcracker" esophagus, extended esophageal myotomy can relieve symptoms. If a clear diagnosis is provided, about 75% of patients will have an improvement of symptoms.

The spectrum of laparoscopic surgery

Laparoscopic procedures have begun to replace many conventional operations because of the avoidance of major surgery and the rapid recovery of the patient. The majority of these traditional operations will be performed laparoscopically in the future. For example, patients who suffer from achalasia will be able to undergo laparoscopic cardiomyotomy and patients with non-cardiac chest pain of esophageal origin will be able to undergo thoracoscopic myotomy. Likewise, a viable alternative to long-term medication with H2 blockers or omeprazole will be laparoscopic posterior vagotomy and anterior lesser curve seromyotomy. As methods are developed to deal with the extraction of large specimens, many ablative procedures will be undertaken by the laparoscopic route. Extraction techniques must not compromise the need for histopathological examination of the resected specimen in cancer resections. The ultimate spectrum of laparoscopic surgery will be determined by the progress in remote handling technology, overcoming the manipulative restrictions inherent in the current instrumentation. Research evaluating the efficacy of new methods will be essential.

Surgery for achalasia of the cardia in children: the Dor-Gavriliu procedure

The Dor-Gavriliu procedure was utilized in six children with achalasia of the cardia from 1983 to 1991. Four boys and two girls (mean age, 10.1 years; range, 3 months to 16 years) presented with symptoms of weight loss (83%), emesis (83%), dysphagia (67%), recurrent respiratory infections (67%), and nocturnal regurgitation (33%). The diagnosis of achalasia was established by barium swallow in all patients; esophageal manometry was used in four patients to confirm the diagnosis. Follow-up ranged from 10 months to 8 years (mean, 3.5 years). Four neurologically normal patients had excellent results with complete resolution of their preoperative symptoms. Two neurologically impaired children, both afflicted with Down's syndrome, had less than excellent results. One moderately impaired child had a good result (required three postoperative bougie dilations over 8 years without demonstration of gastroesophageal reflux); the second, more severely impaired child, had only a fair result (persistent failure to thrive with the development of grade II gastroesophageal reflux). The Dor-Gavriliu procedure uses a transabdominal, anterior esophageal myotomy with incorporation of an effective, nonobstructing, antireflux mechanism that should prevent myotomy reapposition.
