The surgical options for achalasia remain controversial regarding the surgical access route, whether it be transthoracic or transabdominal, the need of, and the type of an added antireflux procedure following an esophagomyotomy. These questions were investigated in an experimental study that used 30 albino rabbits divided into six groups, as follows: transabdominal
Heller
's esophagomyotomy (TAHE), transthoracic
Heller
's esophagomyotomy (TTHE), TAHE and Nissen total fundoplication (NF), TAHE and partial fundoplication (PF), TAHE and modified fundoplication (MF), and a control group. Esophageal transit time (ETT) and
gastroesophageal reflux
(
GER
) were evaluated by scintigraphy on the seventh postoperative day. When an esophagomyotomy was performed either with a transabdominal or transthoracic approach, a significantly increased
GER
rate was found in comparison to the controls. All types of antireflux procedures performed prevented
GER
effectively. Although NF and PF groups showed a significant delay in ETT when compared to the control group (P < 0.001), no such finding was observed in the MF group. In conclusion, an antireflux procedure following an esophagomyotomy is recommended. A modified fundoplication was thus found to be as effective as the other techniques in preventing
GER
, and was even a safer method when obstructive findings following a total or partial fundoplication were considered.

Gastroesophageal reflux
(
GER
) can develop in patients with esophageal achalasia either before treatment or following pneumatic dilatation or
Heller
myotomy. In this study we assessed the value of pre- and postoperative pH monitoring in identifying
GER
in patients with esophageal achalasia. Ambulatory pH monitoring was performed preoperatively in 40 patients with achalasia (18 untreated patients and 22 patients after pneumatic dilatation), 27 (68%) of whom complained of heartburn in addition to dysphagia (group A), and postoperatively in 18 of 51 patients who underwent a thoracoscopic (n=30) or laparoscopic (n=21)
Heller
myotomy (group B). The DeMeester reflux score was abnormal in 14 patients in group A, 13 of whom had been treated previously by pneumatic dilatation. Two types of pH tracings were seen: (1)
GER
in eight patients (7 of whom had undergone dilatation) and (2) pseudo-
GER
in six patients (all 6 of whom had undergone dilatation). Therefore 7 (32%) of 22 patients had abnormal
GER
after pneumatic dilatation. Postoperatively (group B) seven patients had abnormal
GER
(6 after thoracoscopic and 1 after laparoscopic myotomy). Six of the seven patients were asymptomatic. These findings show that (1) approximately one third of patients treated by pneumatic dilatation had
GER
; (2) symptoms were an unreliable index of the presence of abnormal
GER
, so pH monitoring must be performed in order to make this diagnosis; and (3) the preoperative detection of
GER
in patients with achalasia is important because it influences the choice of operation.

Achalasia is a functional disorder of the alimentary tract due to decreased or absent peristalsis of the esophageal body and obstructive outlet of the esophagus. Surgical treatment, eg. esophagomyotomy of the lower esophageal sphincter (LES), was one choice for resolving the problem and its effect was affirmative from reviews of many internationally authorized articles. However, few reports have ever questioned the long-term effects of it. From January 1968 to May 1996, 159 esophageal achalasic patients, 90 males and 69 females, were admitted due to dysphagia or food regurgitation. One hundred and forty-five patients had received 158 operations related to this benign motor disorder. The majority of patients received either modified
Heller
esophagomyotomy (M) or M plus modified Belsy Mark IV antireflux procedure (M+W) for primary treatment of their esophageal disorder, while conditional selection with addition of esophageal resection as advanced procedures for failure of primary surgery. We retrospectively studied these patients, collected their preoperative and postoperative clinical results, analyzed the causes of recurrent symptoms, compared the long-term results in different surgical procedures and searched for the pathogenesis of their failure. The results disclosed that the overall success rate for both methods was 73.1% with 85.7% for patients receiving M+W (56) and 64.9% of M (77) only. Through long-term follow-up, we had an improvement rate of 97.4% at an early stage and 53.3% for M at a late stage and 98.4% and 55.6% for M+W, respectively. The postoperative natural course of achalasic patients could be seen and progressive deterioration of the operated patients with time was noted. Several factors might contribute to the causes of unsuccessful surgery. We summarized them as incomplete myotomy, fused or healed myotomy,
gastroesophageal reflux
(
GER
), mucosal hernia and co-combined antireflux procedure by hypercalibrated or floppy wrapping. Esophagomyotomy or myotomy plus antireflux procedure for the esophagus could be concluded to rather effective in the long-term but palliative treatments for achalasia chronic deterioration of the results could be found for both of them. Defective myotomy and
GER
may be the major causes for their failure. The choice of types of surgery between M and M+W was not the cause of the unsuccessful results whereas the operative strategy and procedures would have a certain significance on the long-term effect.

Incompetence of the lower esophageal sphincter mechanism leads to
gastroesophageal reflux
(
GER
), which is the most common indication for surgery of the gastroesophageal junction. Evaluation, diagnosis, and the modern surgical treatment of
GER
are discussed. Evaluation of patients with severe heartburn include upper endoscopy to evaluate the general condition of the esophagus, stomach, and duodenum; an upper gastrointestinal contrast study for a complete anatomic view of the esophagus and stomach; esophageal manometry to evaluate the function of the esophagus; 24-hour pH monitoring to determine esophageal acid exposure; and a gastric emptying study selectively to determine the presence of a motility disorder. These studies most often prove the diagnosis of
gastroesophageal reflux
, hiatal hernia, Barrett's esophagus, peptic esophageal stricture, paraesophageal hernia, or achalasia. The laparoscopic approach to treatments for these include Nissen fundoplication, Toupet fundoplication, Collis gastroplasty with fundoplication, modified
Heller
myotomy, esophageal diverticulectomy, and revisional operations. These procedures are described in detail. The results of these operations indicate that they are safe and effective and should be considered the new gold standard for correction of gastroesophageal pathology. Laparoscopic surgery has revolutionized many procedures traditionally performed through a laparotomy. Although they are technically more difficult and require a significant amount of time and practice for the surgeon to become proficient, it is becoming apparent that for functional surgery of the gastroesophageal junction laparoscopy is the access of choice.

Primary motor disorders of LES causing dysphagia consist in cardial achalasia and intermedius motor disorder (IMD), the last one different from achalasia because of normal motor pattern of the esophageal body. In this paper diagnostic and therapeutic procedures are examined according to an experience of 94 surgically treated cases (22 rioperations for surgical failures). Cardial dilatation as treatment of choice is recognized only for IMD in which a normal peristaltic behaviour of the esophagus can avoid the high danger of
GER
. Surgical procedure, now laparoscopically performed, consisting in
Heller
's myotomy + Dor partial fundoplication is to be preferred in cases of true achalasia.

For more than three decades experts have debated the relative merits of thoracoscopic
Heller
myotomy (no antireflux procedure) vs. laparoscopic
Heller
myotomy plus Dor fundoplication for treatment of achalasia. The aim of this study was to compare the results of these two methods with respect to (1) relief of dysphagia, (2) incidence of postoperative
gastroesophageal reflux
, and (3) hospital course. Sixty patients with esophageal achalasia were operated on between 1991 and 1996. Thirty underwent a thoracoscopic
Heller
myotomy and 30 had a laparoscopic
Heller
myotomy with a Dor fundoplication. The two groups were similar with respect to demographic characteristics, clinical findings, and extent of manometric abnormalities. Preoperative pH monitoring showed abnormal reflux in two patients in the laparoscopic group. Average hospital stay was 84 hours for the thoracoscopic group and 42 hours for the laparoscopic group. Excellent (no dysphagia) or good (dysphagia less than once a week) results were obtained in 87% of patients in the thoracoscopic group and in 90% of patients in the laparoscopic group. Postoperative pH monitoring showed abnormal reflux in 6 (60%) of 10 patients in the thoracoscopic group and in 1 (10%) of 10 patients in the laparoscopic group. The two patients in the laparoscopic group who had reflux preoperatively had normal reflux scores postoperatively. Laparoscopic
Heller
myotomy with Dor fundoplication was found to be superior to thoracoscopic
Heller
myotomy. Both operations relieved dysphagia, but the laparoscopic approach avoided postoperative reflux and even corrected reflux present preoperatively. In addition, the patients were more comfortable and left the hospital earlier following a laparoscopic myotomy. Whether it is truly possible to perform a
Heller
myotomy without an antireflux procedure in a way that relieves dysphagia and regularly avoids reflux remains questionable.

The Nissen fundoplication, and in particular the laparoscopic Nissen fundoplication, has received widespread acceptance as the most definitive therapy for
gastroesophageal reflux disease
. There remains, however, certain patients who do better with a less aggressive surgical augmentation of the lower esophageal sphincter. Partial fundoplications originated in the early 1960s as an alternative procedure to the Nissen, which was associated with moderately high rates of postoperative side effects. These "more physiologic" procedures have proved successful in the treatment of reflux disease in patients with poor or no esophageal motility. In particular, the use of partial fundoplications in association with
Heller
's myotomy for achalasia has been demonstrated to be well tolerated and to reduce the risk of late dysphasia resulting from uncontrolled
gastroesophageal reflux
(
GER
). The use of partial fundoplications in
GER
patients with normal motility, however, has been less successful. High recurrence rates are documented by many centers with the main cause appearing to be related to a less competent neo-lower esophageal sphincter and a higher rate of wrap herniation. This has led to the current practice of a "tailored approach" to reflux disease, in which all patients receive a thorough preoperative physiologic evaluation to determine the best antireflux procedure for the individual. This is generally a Nissen repair for those with normal motility and either an extrashort "floppy" Nissen or a partial wrap for those with impaired peristalsis.

In patients with achalasia, it has been suggested that pneumatic dilatation could make cardiomyotomy more difficult to perform, diminishing its efficacy and safety. Our aim was to evaluate the efficacy and safety of elective cardiomyotomy after failure of pneumatic dilatation in achalasia. During 14 years, 32 of 276 consecutive patients with achalasia have been operated on because of failure of dilatation therapy. Twenty patients have been followed-up for at least one year after surgery. After failure of dilatation,
Heller
's cardiomyotomy and 180 degrees anterior fundoplication were performed. Clinical status was evaluated before and after surgery. Lower esophageal sphincter pressure and esophageal body basal pressure were measured by manometry, esophageal diameter by barium meal, and
gastroesophageal reflux
by endoscopy and 24-hr esophageal pH monitoring. No technical difficulties were found during operation. Postoperative morbidity was infrequent and mortality was absent. Cardiomyotomy improved clinical status in 19 of 20 patients. The results of surgery were considered excellent or good in 16 patients (80%; CI: 56-94%). The pressure of the lower esophageal sphincter was significantly reduced, falling in most patients to under 10 mm Hg.
Gastroesophageal reflux
appeared after surgery in eight patients, four of them with endoscopic esophagitis, but it was controlled in all patients with medical therapy. In conclusion, cardiomyotomy is a safe and effective therapy in achalasia after failed pneumatic dilatation.

Oesophageal achalasia was treated with modified
Heller
's oesophagomyotomy in 51 patients (19 males, 32 females) via thoracotomy in 47 cases and thoracoscopy in 4 cases. A Belsey Mark IV antireflux procedure was added to transthoracic oesophagomyotomy in two cases, because of extended cardiomyotomy. There were no hospital deaths. The overall improvement rate was 93.5%, with excellent results in 80.6%. Postoperative follow-up averaged 7.4 years. In all four cases of thoracoscopic oesophagomyotomy, simultaneous oesophagoscopy was performed to facilitate the procedure. One patient required repeat surgery 2 months later because of inadequate myotomy. Thirty-one patients, including three with severe gastro-
oesophageal reflux
, received long-term medication. Barrett's oesophagus developed in two of the 31 patients (6.5%) 4.7 and 7.6 years, respectively, after myotomy and squamous cell carcinoma was diagnosed in a 44-year-old woman 2.2 years postoperatively. The study suggests that transthoracic oesophagomyotomy without antireflux procedure can provide excellent long-term relief of dysphagia in oesophageal achalasia and carries a low risk of serious postoperative complications.

During the last decade, minimally invasive surgery has replaced open surgery in the treatment of esophageal achalasia. This new approach, in fact, determines results similar to the open approach, but is associated to a shorter hospital stay, minimal postoperative discomfort, and faster return to regular activity. Between 1991 and 1998, 168 patients underwent a cardiomyotomy by minimally invasive techniques. Good or excellent results were obtained in 85% of patients after thoracoscopic myotomy, and 93% of patients after laparoscopic myotomy and partial fundoplication. The latter procedure was followed by a lower incidence of postoperative
gastroesophageal reflux
(60% versus 17%). Laparoscopic
Heller
myotomy and partial fundoplication has emerged as the procedure of choice for esophageal achalasia, and it should be considered today the primary form of treatment for this disease.
