Laparoscopic Revisional Surgery After Failed Heller Myotomy for Esophageal Achalasia: Long-Term Outcome at a Single Tertiary Center

Robotic Heller's cardiomyotomy for achalasia: early outcomes for a high-volume UK centre

INTRODUCTION

Heller's cardiomyotomy (HCM) is the gold standard treatment for achalasia. Laparoscopic HCM has been shown to be effective with low rates of symptom recurrence, though oesophageal mucosal perforation rates remain high. The aim of this prospective case series is to assess the short-term complication rates and perioperative outcomes for the first cohort of patients undergoing robotic-assisted HCM for achalasia in a single high-volume UK centre.

METHODS

Data were collected from a prospective cohort of patients who underwent robotic HCM at a single high-volume UK centre. Outcomes were assessed using the Eckhard score, which was calculated after their routine postoperative clinic appointments.

RESULTS

Thirteen patients underwent robotic HCM during the study period; this is the second largest reported case series in the European literature. There were no intraoperative oesophageal perforations. Six patients were discharged as day cases, six patients were discharged on the first postoperative day and one patient's hospital stay was two nights. There was a single perioperative complication of urinary retention. All patients reported improvement of symptoms following their operation, and all had a postoperative Eckhard score of less than 3, indicating their achalasia was in remission.

CONCLUSIONS

This cohort has demonstrated that robotic HCM has an exceptional safety profile and results in high levels of symptom resolution, even early in the learning curve. The robotic approach may be superior to laparoscopy as it allows more precise identification and dissection of the oesophageal muscle fibres, which likely reduces the risk of inadvertent mucosal damage or incomplete myotomy.

Laparoscopic Heller-Dor is an effective long-term treatment for end-stage achalasia

BACKGROUND

The end-stage achalasia is a difficult condition to treat, for the esophageal diameter and conformation of the gullet, that may progress to a sigmoid shape. The aim of this study was to examine the outcome of Laparoscopic Heller-Dor in patients with end-stage achalasia, comparing them with patients who had mega-esophagus without a sigmoid shape.

METHODS

From 1992 to 2020, patients with a diagnosis of sigmoid esophagus, or radiological stage IV achalasia (the SE group), and patients with a straight esophagus larger than 6 cm in diameter, or radiological stage III achalasia (the NSE group), were all treated with LHD. The two groups were compared in terms of patients' symptoms, based on the Eckardt score, and on barium swallow, endoscopy and manometry performed before and after the treatment. The failure of the treatment was defined as an Eckardt score > 3, or the need for further treatment.

RESULTS

The study involved 164 patients: 73 in the SE group and 91 in the NSE group. No intra- or postoperative mortality was recorded. The median follow-up was 51 months (IQR 25-107). The outcome was satisfactory in 71.2% of patients in the SE group, and in 89% of those in the NSE group (p = 0.005).

CONCLUSIONS

SE is certainly the worst condition of the disease and the final outcome of LHD, in term of symptom control, is inferior compared to NSE. Despite this, almost 3/4 of the SE patients experienced a significant relieve in symptoms after LHD, which may therefore still be the first surgical option to offer to these patients, before considering esophagectomy.

From laparoscopic to robotic-assisted Heller myotomy for achalasia in a single high-volume visceral surgery center: postoperative outcomes and quality of life

Background

Laparoscopic (LSC) Heller myotomy (HM) is considered the standard procedure for the treatment of achalasia. Robotic platforms, established over the last years, provide important advantages to surgeons, such as binocular 3-dimensional vision and improvement of fine motor control. However, whether perioperative outcomes and long-term results of robotic-assisted laparoscopic (RAL) HM are similar or even superior to LSC technique, especially concerning long-term follow-up, is still debated. Therefore, the aim of the present study was to evaluate intra- and postoperative results as well as long-term quality of life after RAL compared to LSC surgery for achalasia in a single high-volume visceral surgery center.

Methods

Between August 2007 and April 2020, 43 patients undergoing minimally invasive HM for achalasia in a single high-volume Swiss visceral surgery center, were included in the present study. Intra- and postoperative outcome parameters were collected and evaluated, and a long-term follow-up was performed using the gastroesophageal-reflux disease health-related quality of life (GERD-Hr-QuoL) questionnaire.

Results

A total of 11 patients undergoing RAL and 32 undergoing LSC HM were analyzed. Baseline demographics and clinical characteristics were similar. A trend (p = 0.052) towards a higher number of patients with ASA III score treated with RAL was detectable. Operation time was marginally, but significantly, shorter in LSC (140 min, IQR: 136–150) than in RAL (150 min, IQR: 150–187, p = 0.047). Postoperative complications graded Clavien-Dindo ≥ 3 were only observed in one patient in each group. Length of hospital stay was similar in both groups (LSC: 11 days, IQR: 10–13 vs. RAL: 11 days, IQR: 10–14, p = 0.712). Long-term follow-up (LSC: median 89 months, vs. RAL: median 28 months, p = 0.001) showed comparable results and patients from both groups expressed similar levels of satisfaction (p = 0.181).

Conclusions

LSC and RAL HM show similar peri- and postoperative results and a high quality of life, even in long-term (> 24 months) follow-up. Prospective, randomized, controlled multicenter trials are needed to overcome difficulties associated to small sample sizes in a rare condition and to confirm the equality or demonstrate the superiority of robotic-assisted procedures for achalasia. Meanwhile, the choice of the treatment technique could be left to the operating surgeon’s preferences.

Recurrent dysphagia after myotomy for achalasia: pneumatic dilation or POEM? : Which modality offers superior outcomes?

INTRODUCTION

Myotomy is the gold standard treatment for achalasia, yet long-term failure rates approach 15%. Treatment options for recurrent dysphagia include pneumatic dilation (PD), laparoscopic redo myotomy, per oral endoscopic myotomy (POEM), or esophagectomy. We employ both PD and POEM as first-line treatment for these patients. We evaluated operative success and patient reported outcomes for patients who underwent PD or POEM for recurrent dysphagia after myotomy.

METHODS

We identified patients with achalasia who underwent PD or POEM for recurrent dysphagia after previous myotomy within a foregut database at our institution between 2013 and 2021. Gastroesophageal Reflux Disease-Health-Related quality of Life (GERD-HRQL) and Eckardt scores, and overall change in each were compared across PD and POEM groups. Successful treatment of dysphagia was defined by Eckardt scores ≤ 3.

RESULTS

103 patients underwent myotomy for achalasia. Of these, 19 (18%) had either PD or POEM for recurrent dysphagia. Nine were treated with PD and 10 with POEM. The mean change in Eckardt and GERD-HRQL scores did not differ between groups. 50% of the PD group and 67% of the POEM group had resolution of their dysphagia symptoms (p = 0.65). Mean procedure length was greater in the POEM group (267 vs 72 min, p < 0.01) as was mean length of stay (1.56 vs 0.3 days, p < 0.01). There was one adverse event after PD and three adverse events after POEM. After PD, 7 patients (70%) required additional procedures compared to four patients (44%) in the POEM group, consisting mostly of repeat PD.

CONCLUSION

Patients undergoing PD or POEM for recurrent dysphagia after myotomy have similar rates of dysphagia resolution and reflux symptoms. Patients undergoing PD enjoy a shorter length of stay and shorter procedure time but may require more subsequent procedures.

Esophageal Achalasia: Pros and Cons of the Treatment Options

Achalasia is a primary esophageal motility disorder of unknown origin. The goal of treatment is to reduce the resistance caused by a lower esophageal sphincter that fails to relax and is frequently hypertensive. Many treatment options are available to achieve this goal. In this review, we discuss the pros and cons of each therapeutic approach.

Esophageal Achalasia: Evaluation and Treatment of Recurrent Symptoms

BACKGROUND

Esophageal achalasia is a primary esophageal motility disorder of unknown origin. Treatment is palliative and its goal is to decrease the resistance posed by a non-relaxing and often hypertensive lower esophageal sphincter. This goal can be accomplished by different treatment modalities such as pneumatic dilatation, laparoscopic myotomy or peroral endoscopic myotomy. In some patients, however, symptoms tend to recur overtime.

METHODS

A comprehensive literature search was performed on PubMed focused on the management of recurrent achalasia.

RESULTS

The available treatment modalities can be used, alone or in combination. The goal of treatment is to resolve/improve symptoms, avoiding an esophagectomy, an operation linked to significant morbidity.

CONCLUSIONS

The treatment of these patients is often very challenging, and the best results are obtained in centers where a multidisciplinary team-radiologists, gastroenterologists, and surgeons-is present.
