RESUMEN
OBJECTIVE: The aim of this study was to perform an updated Markov analysis to determine the optimal management strategy for patients with an asymptomatic paraesophageal hernia (PEH): elective laparoscopic hernia repair (ELHR) versus watchful waiting (WW). BACKGROUND: Currently, it is recommended that patients with an asymptomatic PEH not undergo repair based on a 20-year-old Markov analysis. The current recommendation might lead to preventable hospitalizations for acute PEH-related complications and compromised survival. METHODS: A Markov model with updated variables was used to compare life-years (L-Ys) gained with ELHR versus WW in patients with a PEH. One-way sensitivity analyses evaluated the robustness of the analysis to alternative data inputs, while probabilistic sensitivity analysis quantified the level of confidence in the results in relation to the uncertainty across all model inputs. RESULTS: At age 40 to 90, ELHR led to greater life expectancy than WW, particularly in women. The gain in L-Ys (2.6) was greatest in a 40-year-old woman and diminished with increasing age. Sensitivity analysis showed that alternative values resulted in modest changes in the difference in L-Ys, but ELHR remained the preferred strategy. Probabilistic analysis showed that ELHR was the preferred strategy in 100% of 10,000 simulations for age 65, 98% for age 80, 90% for age 85, and 59% of simulations in 90-year-old women. CONCLUSIONS: This updated analysis showed that ELHR leads to an increase in L-Ys over WW in healthy patients aged 40 to 90 years with an asymptomatic PEH. In this new paradigm, all patients with a PEH, regardless of symptoms, should be referred for the consideration of elective repair to maximize their life expectancy.

BACKGROUND: Tension is an important factor in hernia repairs. Relaxing incisions to reduce tension are common with ventral hernia repairs, and techniques for relaxing incisions also exist for the hiatus. The aim of this study was to update our original experience with a diaphragm relaxing incision (DRI) in a larger group of patients with longer follow-up. METHODS: A retrospective chart review was performed to identify all patients who had a DRI between August 2016 and September 2021 during hiatal hernia repair. All DRI defects were repaired with permanent mesh remote from the esophagus. Objective follow-up was with chest x-ray, upper GI series (UGI) or both. RESULTS: Seventy-three patients had a total of 79 DRI (right in 63, left in 4, and bilateral in 6 patients), during a primary (n = 52) or redo (n = 21) hiatal hernia repair. Concomitant Collis gastroplasty was used in 38 patients (52%). A single intra-operative complication occurred where the right crus tore during a right DRI. At a median of 15 months, 78% of patients had objective follow-up. There was one hernia through a repaired right DRI (1.2%). No patient had evidence of diaphragm paralysis and there were no mesh infections. The 1-year hernia recurrence rate in these patients was 3.9%. CONCLUSIONS: A DRI can be done safely with minimal risk of intra- or post-operative complications. There was a low rate of herniation through the defect when repaired with permanent mesh. No patient developed a mesh infection despite concomitant Collis gastroplasty in 52% of patients, and there was no evidence of diaphragm paralysis on imaging studies. Further, the low rate of hiatal hernia recurrence suggests efficacy of a DRI to reduce crural closure tension. These excellent outcomes should encourage use of a DRI in patients with a difficult hiatus during hernia repair.

INTRODUCTION: A new repair for gastroesophageal reflux and hiatal hernia, the Nissen-Hill hybrid repair, was developed to combine the relative strengths of its component repairs with the aim of improved durability. In several small series, it has been shown to be safe, effective, and durable for paraesophageal hernia, Barrett esophagus, and gastroesophageal reflux disease. This study represents our experience with the first 500 consecutive repairs for all indications. METHODS: Retrospective study of prospectively collected data for the first 500 consecutive Nissen-Hill hybrid repairs from March 2006 to December 2016, including all indications for surgery. Three quality of life metrics, manometry, radiographic imaging, and pH testing were administered before and at defined intervals after repair. RESULTS: Five hundred patients were included, with a median follow-up of 6.1 years. Indications for surgery were gastroesophageal reflux disease in 231 (46.2%), paraesophageal hernia in 202 (40.4%), and reoperative repair in 67 (13.4%). The mean age was 59, with body mass index of 30 and 63% female. A minimally invasive approach was used in 492 (98%). Thirty-day operative mortality was 1 (0.2%), with a 4% major complication rate and a median length of stay of 2 days. Preoperative to postoperative pH testing was available for 390 patients at a median follow-up of 7.3 months, with the median DeMeester score improving from 45.9 to 2.7. At long-term follow-up (229 responses), all median quality of life scores improved: Quality Of Life in Reflux And Dyspepsia 4 to 6.9, Gastroesophageal Reflux Disease-Health Related Quality of Life 22 to 3, and Swallowing 37.5 to 45 and proton pump inhibitor use dropped from 460 (92%) to 50 (10%). Fourteen (2.8%) underwent reoperation for failure. CONCLUSION: The combined Nissen-Hill hybrid repair is safe and effective in achieving excellent symptomatic and objective outcomes and low recurrence rates beyond 5 years.

OBJECTIVE: The aim of this study was to provide a full HRM data set in patients with a normal functioning fundoplication. BACKGROUND: The Chicago classification was devised to correlate HRM values to the clinical status of patients with swallowing disorder. However, it is unclear whether those values are applicable after fundoplication as the literature is sparse. METHODS: We identified patients with pre- and postoperative HRM who had a normal functioning primary fundoplication as defined by (1) resolution of preoperative symptoms without significant postoperative side effects, (2) no dysphagia reported on a standardized questionnaire given on the day of the postoperative HRM and (3) normal acid exposure determined objectively by esophageal pH-testing. RESULTS: Fifty patients met inclusion criteria for the study. Thirty-three patients (66%) underwent complete fundoplication and 17 patients (34%) underwent posterior partial fundoplication. Postoperative HRM was performed at a median of 12 months after primary surgery. Lower esophageal sphincter (LES) values significantly increased with the addition of a fundoplication. Median integrated relaxation pressure (IRP) was 14 mm Hg ( P = 0.0001), median resting pressure 19.5 mm Hg ( P = 0.0263), and median total length LES was 3.95 cm ( P = 0.0098). The 95th percentile for IRP in a complete fundoplication was 29 versus 23 mm Hg in a partial fundoplication ( P = 0.3667). CONCLUSION: We offer a new standard manometric profile for a normally functioning fundoplication which provides a necessary benchmark for analyzing postoperative problems with a fundoplication. The previously acceptedupper limit defining esophageal outflow obstruction (IRP >20 mm Hg) is not clinically applicable after fundoplication as the majority of patients in this dysphagia-free cohort exceeded this value. Interestingly, there does not seem to be a significant difference in HRM LES values between complete and partial fundoplication.

BACKGROUND: The short-term success of peroral endoscopic myotomy (POEM) is well documented but the durability of the operation is questioned. The aim of this study was to evaluate the clinical outcomes of the POEM procedure for esophageal motility disorders in a large cohort in which all patients had at least 5 years of follow-up. METHODS: All patients from a single center who underwent a POEM between October 2010 and September 2014 were followed for long-term clinical outcomes. Postoperative Eckardt symptom scores of short term and ≥ 5 years were collected through phone interview. Clinical success was defined as an Eckardt score < 3. Overall success was defined as Eckardt score < 3 and freedom from additional interventions. RESULTS: Of 138 patients, 100 patients were available for follow-up (mean age 56, 52% male). The indication for operation was achalasia in 94. The mean follow-up duration was 75 months (range: 60-106 months). Dysphagia was improved in 91% of patients. Long-term overall success was achieved in 79% of patients (80% of achalasia patients, 67% of DES patients). Preoperative mean Eckardt score was 6. At 6 months, it was 1, and at 75 months, it was 2 (p = 0.204). Five-year freedom from intervention was 96%. Overall, 7 patients had additional treatments: 1 balloon dilation (35 mm), 4 laparoscopic Heller myotomy, and 2 redo POEM at a mean of 51 months post-POEM. Ninety-three percent expressed complete satisfaction with POEM. CONCLUSION: A multitude of studies has shown the early benefits of POEM. Here, we show that nearly 80% of patients report clinical success with no significant decrement in symptom scores between their short- and long-term follow-up. Clearly POEM is an effective option for achalasia with durable long-term treatment efficacy.

BACKGROUND: The magnetic sphincter augmentation device (MSA) provides effective relief of gastroesophageal reflux symptoms. Dysphagia after MSA implantation sometimes prompts endoscopic dilation. The manufacturer's instructions are that it be performed 6 or more weeks after implantation under fluoroscopic guidance to not more than 15 mm keeping 3 or more beads closed. The purpose of this study was to assess adherence to these recommendations and explore the techniques used and outcomes after MSA dilation. METHODS AND PROCEDURES: We conducted a multicenter retrospective review of patients undergoing dilation for dysphagia after MSA placement from 2012 to 2018. RESULTS: A total of 144 patients underwent 245 dilations. The median size of MSA placed was 14 beads (range 12-17) and the median time to dilation was 175 days. A second dilation was performed in 67 patients, 22 patients had a third dilation and 7 patients underwent 4 or more dilations. In total, 17 devices (11.8%) were eventually explanted. The majority of dilations were performed with a balloon dilator (81%). The median dilator size was 18 mm and 73.4% were done with a dilator larger than 15 mm. There was no association between dilator size and need for subsequent dilation. Fluoroscopy was used in 28% of cases. There were no perforations or device erosions related to dilation. DISCUSSION: There is no clinical credence to the manufacturer's recommendation for the use of fluoroscopy and limitation to 15 mm when dilating a patient for dysphagia after MSA implantation. Use of a larger size dilator was not associated with perforation or device erosion, but also did not reduce the need for repeat dilation. Given this, we would recommend that the initial dilation for any size MSA device be done using a 15 mm through-the-scope balloon dilator. Dysphagia prompting dilation after MSA implantation is associated with nearly a 12% risk of device explantation.

OBJECTIVE: To review the workload, type and frequency of recurrence, long-term quality of life (QOL), and late oncologic outcomes with endoscopic therapy. BACKGROUND: The short-term oncologic efficacy of endoscopic resection (ER) and ablation for patients with high-grade dysplasia (HGD) or intramucosal adenocarcinoma (IMC) is well-established in the literature. METHODS: A retrospective chart review was performed of the initial 40 patients who had endoscopic therapy from 2001 to 2010 at 1 center by 1 physician. RESULTS: Initial pathology was HGD in 22 and IMC in 18 patients, but 9 patients (41%) with HGD progressed to invasive cancer during endotherapy. The median follow-up was 82 months. Four patients had an esophagectomy, and in the remaining 36 patients, 70 ERs and 111 ablations were performed. The median number of endoscopic sessions was 4 in patients with short segment compared with 7 in patients with long-segment Barrett's. Complete resolution of intestinal metaplasia (CRIM) was achieved in 30 patients (83%) at a median of 21 months. In 18 patients (60%), CRIM was maintained, whereas 12 patients developed recurrence at a median of 14 months. Additional endotherapy (n = 11) led to CRIM again in 10 patients (83%). There were no cancer deaths when CRIM was achieved. Overall survival with endotherapy was 73% at 5 years and 67% at 10 years. Quality of life (QOL) was below population means in 4 of 8 areas, but alimentary satisfaction was good after endotherapy. CONCLUSIONS: Endotherapy is successful in most patients, but multiple sessions are usually required and disease progression can occur. Once CRIM is achieved, recurrence is common and mandates continued endoscopic follow-up. QOL is impaired with endotherapy, but alimentary satisfaction and oncologic outcomes support esophageal preservation with endotherapy for patients with HGD or IMC.

INTRODUCTION AND DESIGN: Node dissection during esophagectomy is an important aspect of esophageal cancer staging. Controversy remains as to how many nodes need to be resected in order to properly stage a patient and whether the removal of more nodes carries a stage-independent survival benefit. A review of the literature performed by a group of experts in the subject may help define a minimum accepted number of lymph nodes to be resected in both primary surgery and post-induction therapy scenarios. RESULTS AND CONCLUSIONS: The existing evidence generally supports the goal of obtaining a minimum of 15 lymph nodes for pathological examination in both primary surgery and post-induction therapy scenarios.

Typical reflux symptoms that respond well to proton pump inhibitor (PPI) therapy are key factors predictive of an excellent outcome with antireflux surgery for gastroesophageal reflux disease (GERD). Our aim was to evaluate whether poor preoperative heartburn (HB) relief with PPIs was associated with a worse outcome after Nissen fundoplication. Patients with a main symptom of HB and a positive pH-test who had a laparoscopic Nissen fundoplication between January 2008 and December 2014 were included. Prior to surgery, patients graded how effectively their HB symptoms were relieved by PPIs. Three groups were defined: good response (76-100% relief), partial response (26-75% relief) and poor response (0-25% relief). Outcomes and satisfaction were assessed at a minimum of 1 year after fundoplication. There were 129 patients who met inclusion criteria and 75 agreed to participate. The median follow-up was 48 months. Prior to Nissen fundoplication 13 patients had a good HB response to PPI-therapy, 36 had a partial response and 26 had a poor response. All patients were satisfied with their HB relief after fundoplication (mean satisfaction score: 9.5/10) and there was no difference in satisfaction score or heartburn relief between groups. Heartburn symptoms that respond poorly to PPI therapy are reliably relieved with a Nissen fundoplication in patients with objectively confirmed GERD. Patient satisfaction after Nissen fundoplication was excellent and was similar in patients with poor versus excellent HB relief with preoperative PPI therapy. Therefore, antireflux surgery is an option for patients with HB and confirmed GERD regardless of the degree of relief of HB symptoms provided by PPI medications.

BACKGROUND: Optimal treatment for symptomatic patients with non-achalasia motility disorders (NAD) such as diffuse esophageal spasm, esophagogastric junction outlet obstruction, and hypercontractile disorder is not well established. POEM has been offered to these patients since it is a less invasive and less morbid procedure but long-term outcomes remain undetermined. The aim of this study was to assess long-term outcomes of POEM for patients with NAD. METHODS: Records of 40 consecutive patients undergoing POEM for NAD from May 2011 to January 2016 at a single center were retrospectively reviewed. Preoperative and 6-month postoperative symptom scores, high-resolution manometry, pH testing, and timed barium swallow (TBS) data were collected. Patients were contacted by phone to obtain long-term symptom assessment. Symptoms were assessed using a standardized symptom questionnaire with scores for symptoms graded according to frequency and the Eckardt score. RESULTS: Ten percent had minor complications with no postoperative sequelae. 90% of patients had significant improvement in their mean Eckardt scores (5.02 vs. 1.12, p < 0.001) at early follow-up. Improvements in chest pain (1.02-0.36, p = 0.001) and dysphagia (2.20 vs. 0.40, p = 0.001) were seen. Significant improvements in manometric pressures and esophageal emptying on TBS were observed across groups. 38% (10/26) of patients had a postoperative pH score > 14.72. Long-term (median 48 months) symptom scores were obtained from 29 (72.5%) patients. 82% of patients (24/29) had sustained symptom improvement. A small increase in the dysphagia scores was reported in the long-term follow-up compared to the immediate postoperative period (0.36-0.89, p = 0.046). CONCLUSIONS: Chest pain and dysphagia are effectively palliated with POEM in patients with non-achalasia disorders of the esophagus. Significant improvements are durable in long-term follow-up. Despite earlier reports by our group suggesting possible inferior outcomes from POEM for this difficult group of patients, this study is far more encouraging. POEM should be considered in the treatment of patients with non-achalasia disorders of the esophagus.

BACKGROUND: Dysphagia after Nissen fundoplication is challenging for patients. High-resolution manometry (HRM) has rarely been studied preoperatively to determine whether manometry values correlated with postoperative dysphagia after fundoplication. We aim to determine whether HRM criteria could predict dysphagia after Nissen fundoplication. METHODS: A retrospective review of single-institution laparoscopic Nissen fundoplications (LNF) from 2013 to 2015 was completed. Dysphagia was graded using a standard scale. Four groups were: those with new postoperative dysphagia (ND), never had dysphagia (NV), continued dysphagia (CD), and resolved dysphagia (RD). Manometry criteria included distal contractile integral (DCI), contraction front velocity (CFV), distal latency (DL), integrated relaxation pressure (IRP), percent peristalsis (PP), and distal esophageal contraction amplitude (DECA). Statistical bootstrapping was used to power sample sizes for ANOVA analysis. RESULTS: Ninety-four patients were included in the original cohort. Statistical bootstrapping sample size was 2992 patients. Among patients who did not have dysphagia prior to LNF, no HRM metric was associated with developing new dysphagia. Among those with dysphagia prior to LNF, a higher DCI, CFV, DL, PP, and DECA were associated with resolution of dysphagia. The RD group was 2.77 times more likely to have a DCI ≥ 1000 mmHg-s-cm compared with the CD group. CONCLUSIONS: HRM criteria could not predict the development of postoperative dysphagia. However, in those with preoperative dysphagia and strong manometry criteria, dysphagia is more likely to resolve after Nissen fundoplication. Meanwhile, in those with preoperative dysphagia and weak manometry, dysphagia may persist and these patients may be better served with a partial fundoplication.

OBJECTIVE: The aim of this study was to determine the accuracy of clinical staging, to assess survival with surgical resection alone, and to determine factors associated with understaging in patients with esophageal adenocarcinoma thought to have limited local-regional disease. BACKGROUND: Primary surgical resection is the preferred treatment in patients with esophageal adenocarcinoma clinically staged to have limited nodal disease. This approach requires reliable clinical staging. METHODS: A retrospective chart review was performed of all patients who had primary esophagectomy for clinical stage T1-3 N0-1 adenocarcinoma (seventh edition AJCC) from January 2002 to May 2013. Clinical and pathologic stages were compared and overall survival was analyzed. RESULTS: There were 88 patients who met inclusion criteria. Final pathology confirmed appropriate clinical staging (≤T3N1) in 76% of patients (67/88). There were 21 patients who were understaged (>T3N1), and in all cases, understaging was based on the presence of advanced nodal (N2 or N3) disease. Factors independently associated with understaging were the presence of dysphagia, tumor length >3âcm, and poor differentiation. At a median follow-up of 35 months, 63% of all patients (55/88) remain alive. The 5-year survival in correctly staged patients was 67%, compared with 33% for those who were understaged (P < 0.0001). CONCLUSIONS: Modern clinical staging will accurately identify the majority of patients with esophageal adenocarcinoma and limited local-regional disease (≤pT3N1). Survival with surgery alone in correctly staged patients was excellent and unlikely to be improved with neoadjuvant therapy. A combination of dysphagia, poor differentiation, and tumor length >3âcm was associated with understaging in 92% of patients. Patients with these factors are likely to have more advanced disease than clinically suspected and may benefit from neoadjuvant therapy before resection.

BACKGROUND: Peroral endoscopic myotomy (POEM) is a novel operation for the treatment of achalasia and other esophageal motility disorders. While POEM has shown excellent short-term safety and efficacy, the long-term symptomatic outcomes after the procedure are unknown. METHODS: Patients from a single center that underwent POEM for treatment of esophageal motility orders and were greater than 5 years removed from their operation were studied. Patients were contacted to assess current symptoms and encouraged to undergo repeat endoscopy for objective follow-up. RESULTS: Thirty-six patients underwent POEM from October, 2010 to February, 2012 and current symptom scores were obtained from 29 patients at median 65-month follow-up. In the 23 patients with achalasia, Eckardt scores were significantly improved from preoperative baseline (mean current 1.7 vs. preoperative 6.4, p < 0.001). Nineteen patients (83%) with achalasia had a symptomatic success (Eckardt ≤3) and none required retreatment for symptoms. Eckardt scores were dramatically improved at 6 months and maintained at 2 years; however, there was a small but significant worsening of symptoms between 2 and 5-years. Of the five patients with EGJ outflow obstruction, all had current Eckardt scores ≤3 but two needed reintervention for persistent or recurrent symptoms, one with a laparoscopic Heller myotomy and another with an endoscopic cricomyotomy and proximal esophageal myotomy extension. At 6-month follow-up, repeat manometry showed decreased EGJ relaxation pressures and esophagram demonstrated improved emptying. 24-h pH monitoring showed abnormal distal esophageal acid exposure in 38% of patients. Fifteen patients underwent endoscopy at 5-years, revealing erosive esophagitis in two (13%), new hiatal hernia in two, and new non-dysplastic Barrett's esophagus in one. The patient with Barrett's underwent a subsequent laparoscopic hiatal hernia repair and Toupet fundoplication. CONCLUSIONS: POEM resulted in a successful palliation of symptoms in the majority of patients after 5 years, though these results emphasize the importance of long-term follow-up in all patients.

INTRODUCTION: The gold standard for the objective diagnosis of gastroesophageal reflux disease (GERD) is ambulatory-pH monitoring off medications. Increasingly, impedance-pH (MII-pH) monitoring on medications is being used to evaluate refractory symptoms. The aim of this study was to determine whether an MII-pH test on medications can reliably detect the presence of GERD. METHODS: Patients referred for persistent reflux symptoms despite pH confirmed adequate acid suppression (DeMeester score ≤14.7) were reviewed retrospectively. All patients who originally had MII-pH testing on medications were re-evaluated with an off medication Bravo-pH study. Acid exposure results (defined by off medication Bravo) were compared to the original on medication MII-pH. RESULTS: There were 49 patients who met study criteria (median age 51). Patients had normal acid exposure during their MII-pH test on medications (average DMS 4.35). Impedance was abnormal (normal ≤47) in 25 of the 49 patients (51%). On subsequent Bravo-pH off medications, 37 patients (75.7%) showed increased esophageal acid exposure (average DMS 36.4). Bravo-pH testing was abnormal in 84% of patients with abnormal MII testing and in 67% with normal MII testing. The sensitivity and specificity of an abnormal MII-pH on medications for increased esophageal acid exposure off medications was 56.8 and 66.7%, respectively. The positive predictive value of confirming GERD from an abnormal MII-pH on medications is 84%, while the negative predictive value is 33.3%. A receiver operating characteristic (ROC) curve was generated and the area under the curve was 0.71, indicating that MII-pH on medications is a fair test (0.7-0.8) in diagnosing pathologic GERD. CONCLUSION: Compared to the gold standard, MII-pH on medications does not reliably confirm the presence of GERD. Excellent outcomes with antireflux surgery are dependent on the presence of GERD; thus, patients should not be offered antireflux surgery until GERD is confirmed with pH testing off medications.

BACKGROUND: Intramucosal esophageal adenocarcinoma can be reliably treated endoscopically. Controversy exists about the use of endotherapy versus esophagectomy for submucosal tumors. Increasingly endotherapy is considered for submucosal tumors in part because of the presumed high mortality with esophagectomy and the perceived poor prognosis in patients with nodal disease. This study was designed to assess survival following primary en bloc esophagectomy (EBE) in patients with submucosal esophageal adenocarcinoma (EAC). METHODS: This is a retrospective review of all patients who underwent EBE for submucosal EAC between 1998 and 2015. No patient had neoadjuvant therapy. RESULTS: There were 32 patients (28M/4F; median age 64 years). The median tumor size was 1.5 cm (0.4-8.0), and the median number of resected nodes was 48 (23-85). There was one perioperative death. Lymph node metastases were present in 7 patients (22%). There was one involved node in four patients and 2, 3, and 31 nodes in one patient each. The one N3 patient received adjuvant therapy. The median follow-up was 87 months. Overall survival at 5 and 10 years was 84 and 70% respectively. Disease-specific survival at 10 years was 90%. Eight patients died, but only three deaths (9%) were related to EAC. Disease-specific survival at 10 years in node-positive patients was 71%. CONCLUSIONS: Survival after primary en bloc esophagectomy for submucosal adenocarcinoma was excellent even in node-positive patients. Mortality with esophagectomy was low and far less than the 22% risk of node metastases in patients with submucosal tumor invasion.

OBJECTIVE: The use of robotic-assisted surgery (RS) has rapidly increased, but public perceptions about RS are largely unknown. The aim of this study was to gain insight into public perceptions about RS, hospitals that have robots, and surgeons that use them. METHODS: A Web-based survey was distributed worldwide. Surveys were collected from July to September 2014, and those with 50% or greater completion were used for analysis. RESULTS: There were 789 surveys, and 747 (95%) were used for analysis. The mean age of respondents was 38.5 years. Most (94%) were from the USA. Over half (53%) had a background in health care, and 13% were physicians. The majority of respondents (86%) had previously heard of RS, but almost 25% indicated that RS was like open, laser, or scarless surgery. Over 20% of respondents indicated that the robot had some degree of autonomy during surgery. Most respondents (72%) indicated that RS was safer, faster, and less painful or offered better results, but when asked if they would choose to have RS, 55% would prefer to have conventional minimally invasive surgery. Hospitals with a robot were thought to be better hospitals by 53% of the respondents. Fewer physicians perceived advantages to RS (30% physicians vs 78% non-physicians p < 0.001), and fewer physicians would prefer RS if they needed surgery (30 vs 49% p = 0.001). One-half of respondents would prefer remote RS by a renowned expert they had never met over having RS by a local non-expert surgeon. CONCLUSIONS: Most respondents perceived benefits to RS, but still preferred conventional minimally invasive surgery if necessary. Misperceptions about the robot indicate a need for patient education prior to RS. Interest by 50% of respondents in remote surgery might allow expert surgeons to do complex procedures without necessitating regionalization of care. Issues identified in this survey merit further exploration.

OBJECTIVE: The aim of the study was to evaluate laser-assisted fluorescent-dye angiography (LAA) to assess perfusion in the gastric graft and to correlate perfusion with subsequent anastomotic leak. BACKGROUND: Anastomotic leaks are a major source of morbidity after esophagectomy with gastric pull-up (GPU). In large part, they occur as a consequence of poor perfusion in the gastric graft. METHODS: Real-time intraoperative perfusion was assessed using LAA before bringing the graft up through the mediastinum. When there was a transition from rapid and bright to slow and less robust perfusion, this site was marked with a suture. The location of the anastomosis relative to the suture was noted and the outcome of the anastomosis ascertained by retrospective record review. RESULTS: Intraoperative LAA was used to assess graft perfusion in 150 consecutive patients undergoing esophagectomy with planned GPU reconstruction. An esophagogastric anastomosis was performed in 144 patients. A leak was found in 24 patients (16.7%) and were significantly less likely when the anastomosis was placed in an area of good perfusion compared with when the anastomosis was placed in an area of less robust perfusion by LAA (2% vs 45%, P < 0.0001). By multivariate analysis perfusion at the site of the anastomosis was the only significant factor associated with a leak. CONCLUSIONS: Intraoperative real-time assessment of perfusion with LAA correlated with the likelihood of an anastomotic leak and confirmed the critical relationship between good perfusion and anastomotic healing. The use of LAA may contribute to reduced anastomotic morbidity.
