RESUMO
Background/Objectives: Despite the increased incidence of esophageal cancer (EC) in elderly people, there are no clear guidelines for its treatment in these patients. The aim of this study was to compare the outcomes of patients ≥ 75 years with resectable EC, receiving either upfront esophagectomy or neoadjuvant treatment. Methods: We retrospectively identified 127 patients with resectable EC ≥ 75 years who underwent esophagectomy between January 2000 and December 2022 at our Clinic in the University Hospital of Padova. The included patients were stratified into two groups: patients undergoing upfront esophagectomy (SURG group) and patients receiving neoadjuvant treatment (NAT group). Results: There were no statistically significant differences in OS (p = 0.7708), DFS (p = 0.7827) and cancer-related survival (p = 0.0827) between the SURG and the NAT group, except for the OS of EAC with stage III-IV, where the NAT group experienced a significant benefit in OS (p = 0.0263). When comparing the two groups, patients receiving neoadjuvant treatment experienced a significantly higher rate of postoperative complications (p = 0.0266). At univariate analysis, neoadjuvant therapy was the only variable strongly associated with postoperative morbidity (p = 0.026). Conclusions: Considering the unique characteristics of elderly patients, the choice of a multimodal approach should be tailored to each case in a multidisciplinary setting and balanced with a potential higher risk of postoperative complications, as well as potential toxicity related to chemoradiation and reduced life expectancy.
RESUMO
BACKGROUND: The treatment of patients with end-stage achalasia with a sigmoid-shaped esophagus is particularly challenging. A modified technique (pull-down technique) has been developed to straighten the esophageal axis, but only a limited number of studies on this topic are available in the literature. This study aimed to compare the outcome of patients who underwent the pull-down technique with that of patients who had a classical laparoscopic Heller-Dor (CLHD) myotomy. METHODS: All patients with a radiologic diagnosis of end-stage achalasia who underwent an LHD myotomy between 1995 and 2022 were considered eligible for the study. All patients underwent symptom score, barium swallow, endoscopy, and manometry tests before and after the procedure was performed. Treatment failure was defined as the persistence or reoccurrence of an Eckardt score (ES) of >3 or the need for retreatment. RESULTS: Of the 94 patients who were diagnosed with end-stage achalasia (male-to-female ratio of 52:42), 60 were treated with CLHD myotomy, and 34 were treated with the pull-down technique. Of note, 2 patients (2.1%), both belonging to the CLHD myotomy group, developed a squamous cell carcinoma during the follow-up. The overall success of LHD myotomy was seen in 76 of 92 patients (82.6%). All patients in both groups achieved a lower ES after surgery. The failure rates were 27.6% (16/58) in the CLHD myotomy group and 5.9% (2/34) in the pull-down technique group (P < .01). CONCLUSION: Our findings confirm that LHD myotomy is an effective treatment of end-stage achalasia and that the pull-down technique further improves the outcome in patients with end-stage achalasia who are difficult to treat.
RESUMO
BACKGROUND: In the last two decades the development of high-resolution manometry (HRM) has changed and revolutionized the diagnostic assessment of patients complain foregut symptoms. The role of HRM before and after antireflux procedure remains unclear, especially in surgical practice, where a clear understanding of esophageal physiology and hiatus anatomy is essential for optimal outcome of antireflux surgery (ARS). Surgeons and gastroenterologists (GIs) agree that assessing patients following antireflux procedures can be challenging. Although endoscopy and barium-swallow can reveal anatomic abnormalities, physiologic information on HRM allowing insight into the cause of eventually recurrent symptoms could be key to clinical decision making. METHOD: A multi-disciplinary international working group (14 surgeons and 15 GIs) collaborated to develop consensus on the role of HRM pre- and post- ARS, and to develop a postoperative classification to interpret HRM findings. The method utilized was detailed literature review to develop statements, and the RAND/University of California, Los Angeles Appropriateness Methodology (RAM) to assess agreement with the statements. Only statements with an approval rate >80% or a final ranking with a median score of 7 were accepted in the consensus. The working groups evaluated the role of HRM prior to ARS and the role of HRM following ARS. CONCLUSION: This international initiative developed by surgeons and GIs together, summarizes the state of our knowledge of the use of HRM pre- and post-ARS. The Padova Classification was developed to facilitate the interpretation of HRM studies of patients underwent ARS.
RESUMO
In recent years, new translational evidence, diagnostic techniques, and innovative therapies have shed new light on esophageal achalasia and revamped the attention on this relatively rare motility disorder. This narrative review aims to highlight the most recent progress and the areas where further research is needed. The four senior authors identified five topics commonly discussed in achalasia management: i.e. pathogenesis, role of functional lumen imaging probe in the diagnostic flow chart of achalasia, how to define the outcome of achalasia treatments, how to manage persistent chest pain after the treatment, and if achalasia patients' may benefit from a regular follow-up. We searched the bibliographic databases to identify systematic reviews, meta-analyses, randomized control trials, and original research articles in English up to December 2023. We provide a summary with the most recent findings in each of the five topics and the critical points where to address future research, such as the immune-genetic patterns of achalasia that might explain the transition among the different phenotypes, the need for a validated clinical definition of treatment success, the use of neuromodulators to manage chest pain, and the need for identifying achalasia patients at risk for cancer and who may benefit of long-term follow-up. Although undoubtedly, progress has been made on the definition and management of achalasia, unmet needs remain. Debated aspects range from mechanistic insights, symptoms, objective measure relationships, and accurate clinical responses to therapeutic interventions. Translational research is eagerly awaited to answer these unresolved questions.

BACKGROUND: The pathophysiological and clinical value of performing High-Resolution Manometry (HRM) after laparoscopic fundoplication (LF) for gastroesophageal reflux disease (GERD) is still unclear and debated. OBJECTIVE: We sought to establish the HRM parameters indicative of functioning fundoplications, and whether HRM could distinguish them from tight or defective ones. METHODS: The study involved patients with GERD who underwent laparoscopic Nissen (LN) or Toupet (LT) fundoplication between 2010 and 2022. HRM and 24-h pH monitoring were performed before and 6 months after surgery. The study population was divided into 5 groups: LN and LT patients with normal 24h-pH findings (LNpH- and LTpH-, respectively); LN and LT patients with pathological 24h-pH findings (LNpH+ and LTpH + groups, respectively); and patients with a postoperative dysphagia intensity score >2 (Dysphagia group). The novel Hiatal Morphology (HM) classification was applied, envisaging 3 different subtypes: HM1 (normal), HM2 (intrathoracic fundoplication), and HM3 (slipped fundoplication). RESULTS: Among the 132 patients recruited during the study period, 46 were in the LNpH- group, 51 in the LTpH- group, 15 in the LNpH + group, 7 in the LTpH + group, and 5 in the Dysphagia group. In multivariate analysis, postoperative abdominal lower esophageal sphincter length (p = 0.001) and HM2 (p < 0.001) were both independently associated with surgical failure. Integrated relaxation pressure was significantly higher in the Dysphagia group than in the LNpH- group. CONCLUSION: This study generated reference HRM values for an effective LF, and confirms that using HRM to assess the neo-sphincter and HM improves the clinical assessment in cases of symptom recurrence.

OBJECTIVE: As achalasia is a chronic disorder, long-term follow-up data comparing different treatments are essential to select optimal clinical management. Here, we report on the 10-year follow-up of the European Achalasia Trial comparing endoscopic pneumodilation (PD) with laparoscopic Heller myotomy (LHM). DESIGN: A total of 201 newly diagnosed patients with achalasia were randomised to either a series of PDs (n=96) or LHM (n=105). Patients completed symptom (Eckardt score) and quality-of-life questionnaires, underwent functional tests and upper endoscopy. Primary outcome was therapeutic success defined as Eckardt score <3 at yearly follow-up. Secondary outcomes were the need for retreatment, lower oesophageal sphincter pressure, oesophageal emptying, gastro-oesophageal reflux and the rate of complications. RESULTS: After 10 years of follow-up, LHM (n=40) and PD (n=36) were equally effective in both the full analysis set (74% vs 74%, p=0.84) and the per protocol set (74% vs 86%, respectively, p=0.07). Subgroup analysis revealed that PD was superior to LHM for type 2 achalasia (p=0.03) while there was a trend, although not significant (p=0.05), that LHM performed better for type 3 achalasia. Barium column height after 5 min at timed barium oesophagram was significantly higher for patients treated with PD compared with LHM, while other parameters, including gastro-oesophageal reflux, were not different. CONCLUSIONS: PD and LHM are equally effective even after 10 years of follow-up with limited risk to develop gastro-oesophageal reflux. Based on these data, we conclude that PD and LHM can both be proposed as initial treatment of achalasia.

This study aimed to investigate changes and perioperative mortality over a 6-year period within the Italian Hospital Information System among patients with gastric cancer (GC) who underwent gastrectomies and to identify risk factors associated with 90-day mortality. Additionally, nationwide differences between high and low-volume hospitals were evaluated. A nationwide retrospective study was conducted using patient hospital discharge records (HDRs) based on the International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) classification. The HDRs were linked to the National Tax Registry records using deterministic record linkage. The data were obtained from the Italian National Outcomes Evaluation Programme (PNE). Multivariate logistic regression was used to examine risk factors for 90-day mortality among patients with GC who underwent partial or total gastrectomies over the period from 2018 to 2020 with adjustment for comorbidities. Overall, the number of patients with GC who underwent total or partial gastrectomies steadily decreased in Italy from 5765 in 2015 to 4291 in 2020 (p < 0.001). The use of the laparoscopic approach more than doubled from 2015 (10.8%) to 2020 (26.3%), with a concomitant conversion rate from laparoscopy to open surgery decreasing from 7.7 to 5.8%. The 30 and 90-day mortality rates remained stable over time (p > 0.05). Low-volume hospitals had higher inpatient, early, and late mortality compared to high-volume hospitals (5.9% vs 3.8%, 6.3% vs 3.8%, and 11.8% vs 7.9%, respectively; p < 0.001). Multivariate logistic regression analysis showed that an advanced age (adjusted odds ratio: 3.72; 95% [CI]: 3.15-4.39; p < 0.001), an open approach (adjusted-OR: 1.69, 95% CI: 1.43-1.99, p < 0.001) and a total gastrectomy (adjusted-OR: 1.44, 95% CI: 1.27-1.64, p < 0.001) were independent risk factors for 90-day mortality. Additionally, patients with GC who referred to high-volume hospitals were 26% less likely to die within 90 days after a gastrectomy than those who underwent surgery in low-volume hospitals. During the 6-year period, surgeons implemented a minimally invasive approach to reduce the conversion over time. Centralisation was associated with better outcomes while advanced age, an open approach, and total gastrectomy were identified as risk factors for 90-day mortality.

Introduction: Several studies reported the advantages of minimally invasive esophagectomy over the conventional open approach, particularly in terms of postoperative morbidity and mortality. The literature regarding the elderly population is however scarce and it is still not clear whether elderly patients may benefit from a minimally invasive approach as the general population. We sought to evaluate whether thoracoscopic/ laparoscopic (MIE) or fully robotic (RAMIE) Ivor-Lewis esophagectomy significantly reduces postoperative morbidity in the elderly population. Methods: We analyzed data of patients who underwent open esophagectomy or MIE/RAMIE at Mainz University Hospital and at Padova University Hospital between 2016 and 2021. Elderly patients were defined as those ≥ 75 years old. Clinical characteristics and the postoperative outcomes were compared between elderly patients who underwent open esophagectomy or MIE/RAMIE. A 1-to-1 matched comparison was also performed. Patients < 75 years old were evaluated as a control group. Results: Among elderly patients MIE/RAMIE were associated with a lower overall morbidity (39.7% vs. 62.7%, p=0.005), less pulmonary complications (32.8 vs. 56.9%, p=0.003) and a shorter hospital stay (13 vs. 18 days, p=0.03). Comparable findings were obtained after matching. Similarly, among < 75 years-old patients, a reduced morbidity (31.2% vs. 43.5%, p=0.01) and less pulmonary complications (22% vs. 36%, p=0.001) were detected in the minimally invasive group. Discussion: Minimally invasive esophagectomy improves the postoperative course of elderly patients reducing the overall incidence of postoperative complications, particularly of pulmonary complications.
RESUMO
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.

Symptoms of Zenker diverticulum can recur whatever the type of primary treatment administered. A modified transoral stapler-assisted septotomy (TS) was introduced in clinical practice a few years ago to improve the results of this mini-invasive technique. The aim of this prospective, controlled study was to assess the outcome of TS in patients with recurrent Zenker diverticulum (RZD), as compared with patients with treatment-naïve Zenker diverticulum (NZD). Patients diagnosed with NZD or RZD, and treated with TS between 2015 and 2021 were compared. Symptoms were recorded and scored using a detailed questionnaire. Barium swallow and endoscopy were performed before and after the TS procedure. In sum, 89 patients were enrolled during the study period: 68 had NZD and 21 had RZD. The patients' demographic and clinical data were similar in the two groups. Three mucosal lesions were detected intra-operatively, and one came to light at post-operative radiological assessment in the NZD group. No mucosal lesions were detected in the RZD group. The median follow-up was 36 months (interquartile range 23-60). The treatment was successful in 97% NZD patients and 95% of RZD patients (P = 0.56). This is the first comparative study based on prospectively collected data to assess the outcome of TS in patients with RZD. Traction on the septum during the procedure proved effective in the treatment of RZD, achieving a success rate that was excellent, and comparable with the outcome in treating NZD.

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.

A precise diagnosis is key to the successful treatment of achalasia. Barium swallow, upper endoscopy and high-resolution manometry provide the necessary information about a patient's anatomy, absence of other diseases, and type of achalasia (I, II, III). High-resolution manometry also has prognostic value, the best results of treatment being obtained in type II achalasia according to the Chicago classification. Abdominal CT scanning and endoscopic ultrasound might be warranted if an underlying malignancy is suspected.

PURPOSE: Radiation-induced esophageal cancer (RIEC) is a rare but severe late consequence of radiotherapy. The literature regarding this topic is predominately limited in describing the risk of this disease. Tumor behavior, treatment strategies, and prognosis of this cancer remain poorly defined. PATIENTS AND METHODS: We collected data of patients who were referred to our unit between 2000 and 2020 for RIEC. After tumor board discussion, upfront surgery or neoadjuvant therapy and surgery were indicated as the main treatment. Preoperative characteristics, long-term and short-term postoperative outcomes of RIEC patients were compared with a 1:1 clustering-matched cohort of patients affected by primary esophageal cancer (PEC). RESULTS: At pre-matching, 54 RIEC and 936 PEC patients were enrolled. The median time between primary irradiation and diagnosis of RIEC was 13.5 years, and the median primary radiation dose was 60 Gy. Compared to the unmatched cohort of PECs, RIEC patients were more frequently female (p = 0.0007), had earlier detection of disease (p = 0.03) and presented more frequently with upper esophageal cancers (p < 0.0001). Neoadjuvant treatment was used less frequently in RIEC patients (p < 0.0001). After matching, the 51 RIEC and 50 PEC patients showed comparable results in terms of exposure to neoadjuvant treatment, surgical radicality and survival outcomes. RIEC patients had more severe postoperative complications (p = 0.04) and a higher proportion of pulmonary complications (p = 0.04). CONCLUSIONS: Curative treatments are feasible for RIEC. Neoadjuvant chemotherapy or chemoradiation can be used in this subgroup, treatment response and long-term outcomes are comparable to those of PEC. The risk of postoperative complications is probably related to the detrimental effect of primary irradiation on lung function.

BACKGROUND: Esophageal perforation (EP) is characterized by high morbidity and mortality. The Pittsburgh Severity Score (PSS) is a scoring system based on clinical factors at the time of EP presentation, intended to guide treatment. The aim of the study is to verify PSS usefulness in stratifying EP severity and in guiding clinical decisions. METHODS: All patients referred to our unit for EP between January 2005 and January 2020 were enrolled. Patients were stratified according to their PSS into three groups (PSS ≤ 2, 3-5, and >5): the postoperative outcomes were compared. The predictive value of the PSS was evaluated by simple linear and logistic regression for the following outcomes: need for surgery, complications, in-hospital mortality, intensive care unit (ICU) and hospital stay, time to refeeding, and need for reintervention. RESULTS: Seventy-three patients were referred for EP (male/female, 46/27). Perforations were more frequently iatrogenic (41.1%) or spontaneous (38.3%). The median PSS was 4 (interquartile range, 2-6). Surgery was required in 60.3% of cases. Pittsburgh Severity Score was associated with ICU admission, hospital stay, need for surgery and reintervention, postperforation complications and mortality. After regression analysis, PSS was significantly predictive of postperforation complications (p < 0.01), in-hospital mortality (p = 0.01), ICU admission (p < 0.01), need for surgical treatment (p < 0.01), and need for reintervention (p = 0.02). CONCLUSION: Pittsburgh Severity Score is useful in stratifying patients in risk groups with different morbidity and mortality. It is also useful in guiding the therapeutic conduct, selecting patients for nonoperative management. Prospective studies are needed to confirm the role of the PSS in the treatment of esophageal perforation. LEVEL OF EVIDENCE: Management, Therapeutic/Care; level IV.

STUDY DESIGN: Case series and systematic review of the Literature. OBJECTIVES: Pharyngo-esophageal perforation (PEP) is a rare, life-threatening complication of anterior cervical spine surgery (ACSS). Best management of these patients remains poorly defined. The aim of this study is to present our experience with this entity and to perform a systematic Literature review to better clarify the appropriate treatment of these patients. METHODS: Patients referred to our center for PEP following ACSS (January 2002-December 2018) were identified from our database. Moreover, an extensive review of the English Literature was conducted according to the 2009 PRISMA guidelines. RESULTS: Twelve patients were referred to our Institution for PEP following ACSS. Indications for ACSS were trauma (n = 10), vertebral metastases (n = 1) and disc herniation (n = 1). All patients underwent hardware placement at the time of ACSS. There were 6 early and 6 delayed PEP. Surgical treatment was performed in 11 patients with total or partial removal of spine fixation devices, autologous bone graft insertion or plate/cage replacement, anatomical suture of the fistula and suture line reinforcement with myoplasty. Complete resolution of PEP was observed in 6 patients. Five patients experienced PEP persistence, requiring further surgical management in 2 cases. At a median follow-up of 18.8 months, all patients exhibited permanent resolution of the perforation. CONCLUSIONS: PEP following ACSS is a rare but dreadful complication. Partial or total removal of the fixation devices, direct suture of the esophageal defect and coverage with tissue flaps seems to be an effective surgical approach in these patients.
RESUMO
Esophageal manometry represents the gold standard technique for the diagnosis of esophageal achalasia because it can detect both the lack of lower esophageal sphincter (LES) relaxation and abnormal peristalsis. From the manometric standpoint, cases of achalasia can be segregated on the grounds of three clinically relevant patterns according to the Chicago Classification v3.0. It is currently unclear whether they represent distinct entities or are part of a disease continuum with the possibility of transition from a pattern to another one. The four cases described in the present report could provide further insights on this topic because the manometric pattern changed from type III to type II in all patients-without any invasive treatment. The cases described here support the hypothesis that the different manometric patterns of achalasia represent different stages in the evolution of the same disease, type III being the early stage, type II an intermediate stage, and type I probably the end stage of achalasia.
RESUMO
BACKGROUND: Staging is inaccurate for cT2N0 esophageal cancer, and patients often are clinically mis-staged. This study aimed to evaluate the outcome after upfront surgery or neoadjuvant therapy, considering the impact of clinical "mis-staging." METHODS: This study reviewed patients with squamous cell carcinoma (SCC) or adenocarcinoma (ADK) of the esophagus who underwent upfront surgery (S group) or neoadjuvant treatment (chemoradiotherapy [CRT] group) for cT2N0 cancer. Overall survival (OS), disease-free survival (DFS), morbidity, and mortality were evaluated. Correctly staged (cTNM = pTNM), understaged (cTNM < pTNM), and overstaged (cTNM > pTNM) patients in the S group and the CRT group were analyzed. Risk factors for unexpected lymph-node involvement were identified in the S group and for cancer-related death in the whole study cohort. RESULTS: The study enrolled 229 patients with cT2N0 esophageal cancer. The 5-year OS rate was 34.2% in the S group versus 55.7% in the CRT group (p = 0.0088). The DFS also was significantly higher (p = 0.01). The morbidity and mortality rates were similar. In the S group, the cTNM was correctly staged for 21.4% and understaged for 63.4% of the patients, with 48.7% of the patients showing unexpected nodal involvement. A tumor length of 3 cm or more was an independent predictor of nodal metastases in SCC (p = 0.03), as was lymphovascular invasion (LVI) in ADK (p < 0.01). Cancer-related mortality was independently associated with lymph-node metastases (p = 0.03) and treatment by upfront surgery (p = 0.01). CONCLUSION: Given the high rate of understaged patients in this study (63.4%), the authors advocate for combining the induction therapy with surgery in cT2N0, achieving better survival with similar morbidity and mortality.

BACKGROUND: Laparoscopic Heller myotomy (HM) has gained acceptance as the gold standard of treatment for achalasia. However, 10-20% of the patients will experience symptom recurrence, thus requiring further treatment including pneumodilations (PD) or revisional surgery. The aim of our study was to assess the long-term outcome of laparoscopic redo HM. METHODS: Patients who underwent redo HM at our center between 2000 and 2019 were enrolled. Postoperative outcomes of redo HM patients (redo group) were compared with that of patients who underwent primary laparoscopic HM in the same time span (control group). For the control group, we randomly selected patients matched for age, sex, FU time, Eckardt score (ES), previous PD, and radiological stage. Failure was defined as an Eckardt score > 3 or the need for re-treatment. RESULTS: Forty-nine patients underwent laparoscopic redo HM after failed primary HM. A new myotomy on the right lateral wall of the EGJ was the procedure of choice in the majority of patients (83.7%). In 36 patients (73.5%) an anti-reflux procedure was deemed necessary. Postoperative outcomes were somewhat less satisfactory, albeit comparable to the control group; the incidence of postoperative GERD was higher in the redo group (p < 0.01). At a median 5-year FU time, a good outcome was obtained in 71.4% of patients in the redo group; further 5 patients (10.2%) obtained a long-term symptom control after complementary PD, thus bringing the overall success rate to 81.6%. Stage IV disease at presentation was independently associated with a poor outcome of revisional LHD (p = 0.003). CONCLUSIONS: This study reports the largest case series of laparoscopic redo HM to date. The procedure, albeit difficult, is safe and effective in relieving symptoms in this group of patients with a highly refractory disease. The failure rate, albeit not significantly, and the post-operative reflux are higher than after primary HM. Patients with stage IV disease are at high risk of esophagectomy.
