RESUMEN

A 45-year-old man who presented with progressive dysphagia of five months duration was diagnosed as a case of oesophageal epiphrenic diverticulum after endoscopic and imaging investigations. He underwent laparoscopic cardiomyotomy with Dor's fundoplication. Myotomy was done from the base of the diverticulum up to 2 cm distal to the gastroesophageal junction. Intraoperative endoscopy was done to check the adequacy of myotomy. Diverticulectomy was not done. Yet the patient had complete relief of symptoms and is well and asymptomatic after two years. Cardiomyotomy with anti-reflux procedures is effective in treating the epiphrenic diverticulum without the need for resection of the diverticulum, which also provides a better prognosis and less morbidity to the patient.

RESUMEN

A 14-year-old girl with a history of asthma was hospitalized because of sudden-onset back pain around her thoracic region that spread to her chest and abdomen. She had been experiencing dysphagia and breathing difficulties for two years, especially after overeating, which often resulted in vomiting undigested food. CT imaging revealed a severely dilated esophagus narrowing at the gastroesophageal junction, suggestive of type 1 achalasia. Further testing confirmed the diagnosis, with an esophageal manometry showing a lack of esophageal contractions and sphincter relaxation. She then underwent a laparoscopic Heller myotomy with relief to her symptoms. This case underscores the rarity of pediatric-onset achalasia with significant esophageal dilation and secondary airway compression, presenting with unusual musculoskeletal and respiratory symptoms. Timely diagnosis and treatment are crucial to prevent worsening and complications.

RESUMEN

BACKGROUND: Systemic inflammatory response is significant prognostic indicator in patients with various diseases. The relationship between prognostic scoring systems based on the modified Glasgow Prognostic Score (mGPS) and achalasia in patients treated with laparoscopic Heller­myotomy with Dor­fundoplication (LHD) remains uninvestigated. This study aimed to examine the role of mGPS in patients with achalasia. METHODS: 457 patients with achalasia who underwent LHD as the primary surgery between September 2005 and December 2020 were included. We divided patients into the mGPS 0 and mGPS 1 or 2 groups and compared the patients' background, pathophysiology, symptoms, surgical outcomes, and postoperative course. RESULTS: mGPS was 0 in 379 patients and 1 or 2 in 78 patients. Preoperative vomiting and pneumonia were more common in patients with mGPS of 1 or 2. There were no differences in surgical outcomes. Postoperative upper gastrointestinal endoscopy revealed that severe esophagitis was more frequently observed in patients with mGPS of 1 or 2 (P < 0.01). The clinical success was 91% and 99% in the mGPS 0 and mGPS 1 or 2 groups, respectively (P < 0.01). CONCLUSIONS: Although severe reflux esophagitis was more common in patients with achalasia with a high mGPS, good clinical success was obtained regardless of the preoperative mGPS.

RESUMEN

BACKGROUND: Video-assisted laparoscopic Heller myotomy (LHM) has become the standard treatment option for achalasia. While robotic surgery offering some specific advantages such as better three-dimensional (3D) stereoscopic vision, hand-eye consistency, and flexibility and stability with the endowrist is expected to be shorter in learning curve than that of LHM for surgeons who are proficient in LHM. The aim of this study was to describe a single surgeon's experience related to the transition from video-assisted laparoscopic to robotic Heller myotomy with Dor fundoplication. METHODS: We conducted a retrospective observational study based on the recorded data of the first 66 Heller myotomy performed with laparoscopic Heller myotomy with Dor fundoplication (LHMD, 26 cases) and with the robotic Heller myotomy with Dor fundoplication (RHMD, 40 cases) by the same surgeon in Department of Thoracic Surgery of The First Affiliated Hospital of Nanchang University in China. The operation time and intraoperative blood loss were analyzed using the cumulative sum (CUSUM) method. Corresponding statistical tests were used to compare outcomes of both serials of cases. RESULTS: The median operation time was shorter in the RHMD group compared to the LHMD group (130 [IQR 123-141] minutes vs. 163 [IQR 153-169]) minutes, p < 0.001). In the RHMD group, one patient (2.5%) experienced mucosal perforation, whereas, in the LHMD group, the incidence of this complication was significantly higher at 19.2% (5 patients) (p = 0.031). Based on cumulative sum analyses, operation time decreased starting with case 20 in the LHMD group and with case 18 in the RHMD group. Intraoperative blood loss tended to decline starting with case 19 in the LHMD group and with case 16 in the RHMD group. CONCLUSIONS: Both RHMD and LHMD are effective surgical procedures for symptom relief of achalasia patients. RHMD demonstrates superior outcomes in terms of operation time and mucosal perforation during surgery compared to LHMD. Proficiency with RHMD can be achieved after approximately 16-18 cases, while that of LHMD can be obtained after around 19-20 cases.

RESUMEN

Approaches to achalasia include non-operative and operative techniques with Heller Myotomy and Per-Oral Endoscopic Myotomy (POEM) at the forefront of palliative strategies. Given the diverse subtypes and the time-dependent failure pattern for achalasia, there is no standard approach. We elect for a POEM for type III achalasia, poor functional status, hostile abdomen, and salvage after the previous myotomy. A Heller myotomy is elected over a POEM for type II achalasia, presence of diverticulum, and hiatal hernia. As long-term outcomes become available, an optimal customized strategy will become clearer.

RESUMEN

Background Heller myotomy (HM) with partial fundoplication is the standard of care for achalasia cardia. However, the choice of partial fundoplication is controversial. In this study, we compared both types of fundoplication concerning subjective and objective parameters. Methodology This prospective comparative study comprised a total of 30 consecutive patients who underwent laparoscopic/robotic HM with either Dor fundoplication (DF) (n = 15) or Toupet fundoplication (TF) (n = 15). Preoperative baseline characteristics, intraoperative details, and postoperative complications were recorded. Patients were followed with Eckardt score, quality of life-related scores, 24-hour pH study, and high-resolution manometry (HRM) at the one-year follow-up. Results There was no significant difference between the two groups regarding preoperative baseline parameters, length of hospital stay, and postoperative complications. The HM+DF group had four (27%) patients with recurrence/failure with none in the HM+TF, but it was not significant (p = 0.79). Symptom scores were similar between the groups at six and 12 months of follow-up. One patient in the HM+DF group and two in the HM+TF group had significant pathological acid reflux (p = 0.483). On HRM, HM+TF showed a trend toward significance in terms of esophagogastric junction (EGJ) relaxation (p = 0.058) with a non-significant difference in median integrated relaxation pressure (p = 0.081). Conclusions The study showed a trend toward lower failure rates and improved EGJ relaxation with similar reflux rates in patients who underwent HM+TF compared to HM+DF. However, long-term follow-up is required to validate our findings with well-defined subjective and objective criteria.

RESUMEN

Diagnosis of spontaneous rupture of the esophagus (Boerhaave syndrome) followed by purulent mediastinitis and pleural empyema has now been greatly simplified due to CT. The main thing is to suspect this syndrome in a timely manner. Methods of surgical treatment of this disease are still being discussed. We present successful laparoscopic treatment of spontaneous rupture of the esophagus.

RESUMEN

Objective: Laparoscopic Heller myotomy and Dor fundoplication has become the gold standard in treating esophageal achalasia and robotic surgical platform represents its natural evolution. The objective of our study was to assess durable long-term clinical outcomes in our cohort. Methods and Procedures: Between June 1, 1999 and June 30, 2019, 111 patients underwent minimally invasive treatment for achalasia (96 laparoscopically and 15 robotically). Fifty-two were males. Mean age was 49 years (20 - 96). Esophageal manometry confirmed the diagnosis. Fifty patients underwent pH monitoring study, with pathologic reflux in 18. Preoperative esophageal dilation was performed in 76 patients and 21 patients received botulin injection. Dysphagia was universally present, and mean duration was 96 months (5 - 480). Results: Median operative time was 144 minutes (90 - 200). One patient required conversion to open approach. Four mucosal perforations occurred in the laparoscopic group and were repaired intraoperatively. Seven patients underwent completion esophageal myotomy and added Dor fundoplication. Upper gastrointestinal series was performed before discharge. Median hospital stay was 39 hours (24 - 312). Median follow up was 157 months (6 - 240), and dysphagia was resolved in 94% of patients. Seven patients required postoperative esophageal dilation. Conclusions: Minimally invasive Heller myotomy and Dor fundoplication are feasible. The operation is challenging, but excellent results hinge on the operative techniques and experience. The high dexterity, three-dimensional view, and the ergonomic movements of robotic surgery allow application of all the technical elements, achieving the best durable outcome for the patient. Robotic surgery is the natural evolution of minimally invasive treatment of esophageal achalasia.

RESUMEN

OBJECTIVE: To evaluate the early and long-term postoperative outcomes in patients with recurrent achalasia, as well as the main features of surgical treatment. MATERIAL AND METHODS: There were 7 patients (4 men and 3 women) with recurrent achalasia. Mean age of patients was 42.3±13.5 years, body mass index - 22.7±3.3 kg/m2. Physiological status ASA grade 1-3 was observed in all patients. Concomitant diseases were diagnosed in 5 (71.4%) cases. Six (85.7%) patients underwent laparoscopic Heller cardiomyotomy with Dor fundoplication. Peroral endoscopic myotomy (POEM) was performed in 1 (14.3%) patient. Mean preoperative Eckardt score was 10.7±1.4 points, mean GERD-HRQL score - 42.7±6.4 points. According to preoperative radiography, 5 (71.4%) patients had achalasia stage III, 2 (28.6%) ones - stage IV. RESULTS: All patients underwent laparoscopic Heller esophagocardiomyotomy with anterior Dor fundoplication and posterior partial fundoplication with posterior cruroraphy. Intraoperative complications (perforation of esophageal mucosa) occurred in 3 (42.9%) patients. Mean surgery time was 130±56 min, mean blood loss - 37 ml (35-205 ml), mean hospital-stay - 11.3±7.7 days. Postoperative complications Clavien-Dindo grade 3-4 were detected in 1 (14.3%) patient.

RESUMEN

The surgical management of achalasia with sigmoid esophagus involves multiple significant challenges due to the difficulty in endoscopic assessment, esophageal motility disorders, and potential complication and recurrence rates. We report a 34-year-old female with worsening dysphagia and malnourishment due to advanced achalasia. An esophagogastroduodenoscopy (EGD) revealed an esophageal dilation, tortuosity, and distal blockage with undigested food. Esophagram demonstrated the typical bird beak appearance with a tortuous dilated esophagus. She underwent a laparoscopic Heller myotomy with Dor fundoplication with no complications. She was discharged on the second postoperative day, tolerating clear liquids, and then a normal diet within six weeks. Several treatment options exist for the surgical management of a sigmoid esophagus with achalasia, but there is no clear gold standard. In our case, Heller myotomy with Dor fundoplication provided favorable results, but treatment should be individualized for each case.

RESUMEN

Diagnosis of esophageal disorders is well ahead of available treatment options. With HRM, for example, one can identify numerous conditions and their variants, which may lose meaning if the clinical and therapeutic implications of these subclassifications are limited. We report an exemplary case of a patient with hiatal hernia complaining of reflux, dysphagia, and chest pain refractory to medical treatment. Jackhammer esophagus was diagnosed and a hybrid approach consisting of POEM and concomitant crural repair and Dor fundoplication is proposed.

RESUMEN

BACKGROUND: Manometry is the gold standard diagnostic test for achalasia. However, there are incidences where manometry cannot be obtained preoperatively, or the results of manometry is inconsistent with the patient's symptomatology. We aim to determine if intraoperative use of EndoFLIP can provide a diagnosis of achalasia and provide objective information during Heller myotomy and Dor fundoplication. METHODS: To determine the intraoperative diagnostic EndoFLIP values for patients with achalasia, we determined the optimal cut-off points of the distensibility index (DI) between patients with a diagnosis of achalasia and patients with a diagnosis of hiatal hernia. To evaluate the usefulness of EndoFLIP values during Heller myotomy and Dor fundoplication, we obtained a cohort of patients with EndoFLIP values obtained after Heller myotomy and after Dor fundoplication as well as Eckardt score before and after surgery. RESULTS: Our analysis of 169 patients (133 hiatal hernia and 36 achalasia) showed that patients with DI < 0.8 have a >99% probability of having achalasia, while DI > 2.3 have a >99% probability of having hiatal hernia. Patients with a DI 0.8-1.3 have a 95% probability of having achalasia, and patients with a DI of 1.4-2.2 have a 94% probability of having a hiatal hernia. There were 40 patients in the cohort to determine objective data during Heller myotomy and Dor fundoplication. The DI increased from a median of 0.7 to 3.2 after myotomy and decreased to 2.2 after Dor fundoplication (p < 0.001). The median Eckardt score went down from a median of 4.5 to 0 (p < 0.001). CONCLUSIONS: Our study shows that intraoperative use of EndoFLIP can facilitate the diagnosis of achalasia and is used as an adjunct to diagnose achalasia when symptoms are inconsistent. The routine use of EndoFLIP during Heller myotomy and Dor fundoplication provides objective data during the operation in a group of patients with excellent short-term outcomes.

RESUMEN

BACKGROUND: Laparoscopic Heller-myotomy with Dor-fundoplication (LHD) is the standard surgical treatment for achalasia; however, surgical outcomes over a period greater than 10 years have not been well-explored. The objective of this study was to evaluate the long-term outcomes of LHD for achalasia based on a single-center experience. METHODS: Patients who underwent LHD between 1994 and 2019 were included. Of these, we excluded patients who had undergone foregut surgery or whose follow-up data were unavailable. Esophagogastroduodenoscopy (EGD) findings and postoperative persistent and/or recurrent symptoms had been assessed annually. Disease-free rates were calculated using Kaplan-Meier analysis. RESULTS: A total of 530 patients (mean age 45.0 years with 267 men) were included. The median follow-up period was 50.5 months. More than 10 years' data were available in 78 patients (14.7%). The cumulative rates of freedom from dysphagia, vomiting, chest pain, and Eckardt score > 3 at 10 years after LHD were 80.1%, 97.5%, 96.3%, and 73.5%, respectively. Probability of esophagitis during 10 years after surgery was 34.4% of patients based on Kaplan-Meier estimation. Approximately 3/4th of patients who had post-LHD esophagitis showed mild esophagitis of Los Angeles classification grade A. Fifteen patients (2.8%) were required a revision of primary LHD. Six patients (1.2%) developed esophageal cancer with an incidence was as high as 219.8/100,000 person-year. All patients with esophageal cancer were found to have early stage tumors that were successfully resected. CONCLUSIONS: Symptomatic relief post-LHD lasted for over 10 years. The incidence rate of esophageal cancer was high. Regular EGD surveillance seems to be helpful for early detection of esophageal cancer early.

RESUMEN

PURPOSE: Esophageal dysmotility and disorders of the lower esophageal sphincter are well documented in morbidly obese patients. Esophageal achalasia has been reported in up to 1% of obese patients but the development of such esophageal motility disorder after laparoscopic sleeve gastrectomy (LSG) is extremely rare. The purpose of this video was to demonstrate the management of a type II esophageal achalasia diagnosed in a 46-year-old female patient 4-year after LSG. MATERIALS AND METHODS: An intraoperative video has been anonymized and edited to demonstrate the feasibility of laparoscopic Heller myotomy and anterior Dor fundoplication on the mentioned patient. RESULTS: The operation started with the section of the perigastric adhesions. Proceeding in a clockwise direction, the esophagogastric junction, the anterior esophageal wall, and the His angle were freed. A residual slightly dilated fundus was found and isolated. After mobilization of the distal esophagus and identification of the anterior vagus nerve, a "hockey stick" myotomy was carried out for 6 cm on the esophagus and for 2 cm on the gastric side. An anterior Dor fundoplication was fashioned using the residual gastric fundus. CONCLUSION: Esophageal achalasia in patients that previously underwent LSG is exceptional but should always be suspected in case of pathognomonic symptoms onset. In tertiary referral centers, laparoscopic Heller myotomy and, if technically feasible, an anterior Dor fundoplication seem safe and effective to relieve gastroesophageal outflow obstruction and prevent gastroesophageal reflux.

RESUMEN

BACKGROUND: Achalasia is a chronic motility disorder which may require surgical interventions to effectively manage patients' symptoms and improve functional status. In late stage achalasia, patients may present with sigmoid-shaped esophagus which complicates traditional treatment approaches for achalasia as the esophagus is massively dilated and dysfunctional with delicate tissue integrity. Severe Achalasia with sigmoid esophagus imposes significant challenge to surgeons and treating physicians. Various assessment modalities and treatment approaches have been tried. Surgical treatment continues to be controversial. Some have argued that a less aggressive approach similar to that in early Achalasia results in satisfactory outcomes. Others have argued a more aggressive approach of esophagectomy is necessary. We present a review of the challenges encountered in each approach with recommendation for selecting the right treatment for the individual cases. CONCLUSIONS: Different treatment options for sigmoid type achalasia are available with ongoing controversy among the options. Heller myotomy with Dor fundoplication can provide satisfactory symptoms improvement and treatment outcomes.

RESUMEN

Esophageal achalasia is a primary esophageal motility disorder characterized by lack of peristalsis and by incomplete or absent relaxation of the lower esophageal sphincter in response to swallowing. The cause of the disease is unknown. The goal of treatment is to eliminate the functional outflow obstruction at the level of the gastroesophageal junction, therefore allowing emptying of the esophagus into the stomach. They include the laparoscopic Heller myotomy with partial fundoplication, pneumatic dilatation, and peroral endoscopic myotomy. Esophagectomy is considered as a last resort for patients who have failed prior therapeutic attempts. In this evidence and experience-based review, we will illustrate the technique and results of the surgical treatment of esophageal achalasia and compare it to the other available treatment modalities.

RESUMEN

BACKGROUND: Noncardiac chest pain often coexists with dysphagia in patients diagnosed with achalasia. The current standard treatment for achalasia, laparoscopic Heller myotomy with Dor fundoplication, has an insufficient effect on noncardiac chest pain. The aim of this study is to investigate the efficacy of circumferential Heller myotomy on esophageal chest pain in patients with achalasia. METHODS: Twenty patients diagnosed with achalasia who complained of noncardiac chest pain were recruited and underwent circumferential Heller myotomy. Using an institutional achalasia database, we randomly selected 60 patients who underwent standard laparoscopic Heller myotomy with Dor fundoplication, based on a 3-to-1 propensity score-matching analysis. We compared surgical outcomes between the circumferential Heller myotomy and the laparoscopic Heller myotomy with Dor fundoplication groups. RESULTS: Patients undergoing circumferential Heller myotomy had a higher rate of postoperative noncardiac chest pain relief than the laparoscopic Heller myotomy with Dor fundoplication group [95% (19/20) vs. 75% (45/60), p = 0.045]. No differences in dysphagia and vomiting were found between groups (p = 0.783 and p = 0.645, respectively). Patients in the circumferential Heller myotomy group had significantly better esophageal clearance. The prevalence of reflux endoscopic esophagitis was higher in the circumferential Heller myotomy group than in the control group [35.0% (7/20) vs. 10.0% (6/60), p = 0.015]. CONCLUSIONS: There is promising early evidence that circumferential Heller myotomy may be effective in the treatment of achalasia-related chest pain. Further research, including larger randomized studies with long-term follow-up, is warranted.

RESUMEN

Achalasia is a primary esophageal motility disorder characterized by lack of esophageal peristalsis and partial or absent relaxation of the lower esophageal sphincter in response to swallowing. Available treatment modalities are not curative but rather intend to relieve patient' symptoms. A laparoscopic Heller myotomy with Dor fundoplication is associated with high clinical success rates and low incidence of postoperative reflux. A properly executed operation following critical surgical steps is key for the success of the operation.

RESUMEN

Laparoscopic Heller Myotomy (LHM) with partial fundoplication has become the treatment of choice for esophageal achalasia. However, the choice of the partial fundoplication is debated. The aim of this study was to compare outcomes for Dor and Toupet fundoplication after LHM. A systematic search of randomized controlled trials comparing Dor and Toupet fundoplication was performed using PubMed, EMBASE and Web of Science. Three studies met the inclusion criteria. Overall, 174 patients were included in the analysis. The postoperative abnormal acid reflux [pooled Risk Ratio 0.98 (95% HPD 0.54-1.80)] and dysphagia [pooled Risk Ratio 1.03 (95% HPD 0.51-2.05)] were similar comparing Dor and Toupet fundoplication. The % total time pH ≤ 4 [estimated pooled mean difference -0.08 (95% HPD -1.04-0.90)] and DeMeester score [estimated pooled mean difference 0.51 (95% HPD -0.90-1.94)] were comparable. Additionally, the operative time [estimated pooled mean difference 0.02 (95% HPD -0.53-0.52)] and iatrogenic esophageal perforation [pooled Risk Ratio 1.05 (95% HPD 0.52-2.10)] were similar in the two groups. Dor and Toupet fundoplication after laparoscopic Heller myotomy seem comparable in term of postoperative abnormal acid exposure and dysphagia. The choice of the partial fundoplication should be left to surgeon experience and tailored on each patient.
