RESUMO
INTRODUCTION: Laparoscopic paraesophageal hernia (PEH) repair has a high hernia recurrence rate. The aim of this study was to assess the 5-year hernia recurrence rate after PEH repair using a combination of bioresorbable mesh and advanced surgical techniques to address tension as needed in a prospective group of patients. METHODS: In 2016 a prospective database was established for 50 patients undergoing primary, elective PEH repair with a new bioresorbable mesh (Phasix-ST). Intra-operatively, tension was addressed with Collis gastroplasty and / or diaphragm relaxing incisions as needed. All 50 patients from the initial study were tracked and asked to return for objective follow-up. Recurrence was considered present for any hernia > 2 cm in size. RESULTS: Objective follow-up was obtained in 27 of the original 50 patients (54%) at a median of 5.25 years after their PEH repair. Prior to the 5-year follow-up, 5 patients had a known recurrent hernia. Objective evaluation at 5 years identified an additional 3 recurrences, for a total recurrence rate of 25% (8/32 patients). The hernia recurrence rate in patients with a Collis gastroplasty was significantly lower compared to those without a Collis (7% vs 54%, p=0.008). Two patients underwent re-operation for hernia recurrence. No patient had a mesh infection or mesh erosion. CONCLUSION: The combination of Phasix-ST mesh and tension reducing techniques during PEH repair led to a 25% hernia recurrence rate at 5 years. The addition of a Collis gastroplasty led to significantly fewer hernia recurrences and is indicative of the potential for esophageal shortening in many patients with a PEH. The long-term safety and efficacy of Phasix-ST mesh in combination with surgical technique for PEH repair is confirmed.
RESUMO
INTRODUCTION: Screening colonoscopy (SC) is widely accepted and has been shown to decrease the rate of colorectal cancer death. Guidelines and acceptance of screening for Barrett's esophagus (BE) are less established despite the fact that esophageal adenocarcinoma (EA) remains the fastest increasing cancer in the USA. The aim of this study was to assess the timing and frequency of SC in patients ultimately found to have EA and to evaluate the presence of symptoms and risk factors that might have prompted an esophagogastroduodenoscopy (EGD) and potentially earlier diagnosis of the EA. METHODS: A retrospective chart review was performed to identify all patients who were referred to a single center with esophageal cancer between July 2016 and November 2022. Patients with any histology other than adenocarcinoma were excluded. RESULTS: There were 221 patients referred with EA. Of these, a SC had been done prior to the diagnosis of EA in 108 patients (49%): 96 men and 12 women. A total of 203 SC had been done (range 1-7 per patient), and 47% of patients had more than 1 SC. The median interval from the last SC to the diagnosis of EA was 2.9 years. At the time of SC, gastroesophageal reflux disease (GERD) symptoms or chronic acid suppression medication use was reported by 81% of patients, and 80% had an American Society of Gastrointestinal Endoscopy (ASGE) indication for a screening EGD. Only 19 patients (18%) that had a SC had an EGD at any time prior to the diagnosis of EA, and in these patients, 74% had erosive esophagitis or BE. The EA in most patients was stage III or IV and associated with lymph node metastases. CONCLUSIONS: Nearly one-half of patients ultimately diagnosed with EA had one or more SCs, and most of these patients had GERD symptoms, were using acid suppression medications or had an ASGE indication for a screening EGD. Despite this, only 18% had an EGD prior to the EA diagnosis. The addition of an EGD at the time of SC in these patients may have allowed the detection of BE or EA at an early, endoscopically curable stage and represents a missed opportunity to intervene in the natural history of this disease.

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: The aim was to evaluate the clinical significance of multiple rapid swallows (MRS) during high-resolution manometry (HRM) prior to fundoplication. Despite pre-operative HRM, up to 38% of patients report post-fundoplication dysphagia. Suggestion that MRS improves prediction of dysphagia after fundoplication has not been investigated when using a tailored approach. We hypothesize response to MRS is predictive of dysphagia after tailored fundoplication. METHODS: A retrospective cohort study was performed on patients undergoing HRM with MRS provocation 5/2019-7/2021 at a single institution. Patients who underwent subsequent index laparoscopic fundoplication, without peptic stricture or achalasia, were included. After performing standard 10-swallow HRM, MRS provocation was performed. Patient-reported dysphagia frequency scores were collected at initial consultation and post-operative follow-up. At least weekly symptoms were considered clinically significant. Normal MRS response was defined as adequate deglutitive inhibition and MRS contractile response. Fundoplications were tailored based on standard HRM values. RESULTS: HRM was performed in 1201 patients, 220 met inclusion criteria. Clinically significant pre-operative dysphagia was reported by 85 (38.6%). Patients undergoing partial fundoplication (n = 123, 55.9%) had lower mean distal contractile integer, distal esophageal contraction amplitude, and percent peristalsis (p < 0.005). Post-operatively, 120 (54.5%) were without dysphagia, 59 (26.8%) had improved dysphagia, 26 (11.8%) had unchanged dysphagia, and 15 (6.8%) reported new dysphagia. There was no statistical difference in early or late dysphagia outcome between tailored fundoplication groups (p = 0.69). On univariate and multivariate analysis, neither MRS response, nor standard HRM metrics were significantly associated with post-operative dysphagia. Younger age (OR 0.96, 95% CI 0.94-0.986, p = 0.042) and the presence of pre-operative dysphagia (OR 2.54, 95% CI 1.17-5.65, p = 0.015) were significant predictors of post-operative dysphagia. CONCLUSION: The risk of clinically significant dysphagia post-fundoplication is low when using a tailored approach based on standard HRM metrics. Additional data provided by MRS does not add to surgical decision-making using the investigated approach.

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.

BACKGROUND: Post-operative pain control and narcotic over-utilization are challenging issues for surgeons in all fields. While virtual reality (VR) has been increasingly applied in various fields, its feasibility and efficacy in the peri-operative period has not been evaluated. The aim of this study was to examine the experience of an integrated VR protocol in the perioperative setting. METHODS: Patients undergoing minimally invasive foregut surgery at a single institution were randomized to receive a series of VR meditation/mindfulness sessions (VR) or to standard care after surgery (non-VR). Post-operative pain levels, narcotic utilization and patient satisfaction were tracked. RESULTS: Fifty-two patients were enrolled with 26 in each arm. Post-operative pain scores, total narcotic utilization, and overall satisfaction scores were not significantly different between the two groups. For patients in the VR arm, sessions were able to be incorporated into the perioperative routine with little disruption. Most (73.9 %) were able complete all six VR sessions and reported low pain, anxiety, and nausea scores while using the device. A high proportion responded that they would use VR again (76.2 %) or would like a VR program designed for pain (62.0 %). There were no complications from device usage. CONCLUSION: VR is a safe and simple intervention that is associated with high patient satisfaction and is feasible to implement in the perioperative setting. While the current study is underpowered to detect difference in narcotic utilization, this device holds promise as an adjuvant tool in multimodal pain and anxiety control in the peri-operative period.

INTRODUCTION: Laparoscopic paraesophageal hernia (PEH) is associated with a low morbidity and mortality but an objective hernia recurrence rate in excess of 50% at 5 years. Biologic mesh has not been shown to reduce hernia recurrence rates. Recently, a new bioresorbable mesh made with poly-4-hydroxybutyrate with a Sepra-Technology coating on one side (Phasix-ST mesh) has become available. The aim of this study was to evaluate the feasibility, safety, and short-term efficacy of Phasix-ST mesh for reinforcement of the primary crural closure in patients undergoing elective, laparoscopic PEH repair. METHODS: A prospective database was initiated and maintained for all patients undergoing PEH repair with the use of Phasix-ST mesh. We retrospectively reviewed the records of consecutive patients who had an elective, first-time laparoscopic PEH repair with Phasix-ST mesh and who completed their 1-year objective follow-up study. Patients having a reoperation, non-laparoscopic repair, or who failed to comply with the objective follow-up were excluded. RESULTS: To achieve the desired 50 patients with 1-year objective follow-up, we reviewed the records of 90 consecutive PEH patients. In the final cohort of 50 patients, there were 32 females (64%) and 18 males. The median age of the patients at surgery was 67 years (range 44-84). The operation was PEH repair with fundoplication alone in 29 patients (58%) and PEH repair with Collis gastroplasty and fundoplication in 21 patients (42%). Phasix-ST mesh was used for crural reinforcement in all patients, and there were no intraoperative issues with the mesh or any difficulty placing or fixating the mesh at the hiatus. A diaphragm relaxing incision was performed in 2 patients (4%). The mean length of hospital stay was 2.8 days, and there was no major morbidity or mortality. On the 1-year objective follow-up study (median 12 months) a recurrent hernia was found in 4 patients (8%). No patient that had a Collis gastroplasty or a relaxing incision had a recurrent hernia. No patient had a reoperation. No patient had a mesh infection or mesh erosion. CONCLUSIONS: Phasix-ST mesh reinforcement of the crural closure during laparoscopic primary, elective PEH repair was associated with no adverse mesh-related events such as infection or erosion. Phasix-ST crural reinforcement in combination with tension-reduction techniques when necessary resulted in a very low (8%) objective hernia recurrence rate at a median follow-up of 1 year. These results demonstrate the safety of Phasix-ST mesh for use at the hiatus for crural reinforcement. This safety, along with the encouraging short-term efficacy for reducing hernia recurrence, should encourage further studies using the combination of resorbable biosynthetic mesh crural reinforcement and tension-reducing techniques during repair of paraesophageal hernias.

INTRODUCTION: Impedance-pH testing (MII-pH) while patients are on acid suppression medications is frequently used to evaluate persistent reflux symptoms. The aim of this study was to determine whether MII-pH on medications can reliably identify patients with gastroesophageal reflux disease (GERD) as defined by pathologic esophageal acid exposure off medications, and to determine if there is a threshold of total reflux episodes on medications where pH testing off medications may be unnecessary. METHODS: A retrospective review identified all patients between 1/2010 and 4/2017 who underwent MII-pH testing on PPI medications and subsequently had pH testing off medications. GERD was defined on pH testing off medications by an abnormal DeMeester Score (DMS) and on MII-pH on medications by ≥ 48 total reflux episodes. Patients with an abnormal DMS by MII-pH on medications were excluded. RESULTS: There were 71 patients, (22 males; 49 females), with a median age of 52 years. Based on ≥ 48 total reflux episodes by MII-pH testing on medications, 42 patients (59%) had GERD. When tested off medications, an abnormal DMS was present in 44 patients (62%). Among those with GERD based on impedance testing on medications, 31% did not have GERD based on pH testing off medications. Further, in the 29 patients with ≤ 48 total reflux episodes on MII-pH (normal test), 15 patients (52%) had pathologic acid exposure off medications. When there were > 73 reflux events with MII-pH on medications, all 15 patients in our series had pathologic acid exposure on pH testing off medications. CONCLUSION: MII-pH testing on medications in patients with refractory GERD symptoms does not reliably correlate with a diagnosis of GERD as defined by pathologic esophageal acid exposure off medications. The commonly used abnormal MII-pH test value of ≥ 48 total reflux episodes is not validated and should not be used. However, in our series, patients with > 73 total reflux episodes had a high likelihood of having pathologic acid exposure off medications. Overall, the preferred strategy to evaluate patients with persistent GERD symptoms on acid suppression therapy should be pH testing off 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.

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: 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.

BACKGROUND: Giant fibrovascular esophageal polyps are rare benign intraluminal tumors that originate from the submucosa of the cervical esophagus [Owens et al. (JAMA 103: 838-842, 1994), Totten et al. (JAMA 25:606-622, 1953)]. Due to their indolent course, these tumors tend to reach enormous proportions before patients develop symptoms. Accurately diagnosing these tumors is difficult, as endoscopy may miss 25% of these lesions because these polyps exhibit normal intact esophageal mucosa [Levine et al. (JAMA 166: 781-787, 1996)]. METHODS: Surgical resection has been the treatment of choice. We present a video that illustrates the feasibility of an endoscopic approach. TECHNIQUE/CASE: A 62-year-old man presented to our clinic with a pedunculated esophageal mass. During this time, he developed progressive dysphagia to solid foods. A complete workup confirmed the presence of a giant polyp and endoscopic resection under general anesthesia was planned. Using an endoscopic snare-technique, a 16 cm × 3 cm polyp was amputated and retracted out of the oropharynx. Upon repeat endoscopy a second 7 cm × 3 cm polyp was discovered originating proximal to the larger polyp. Again, removal of this polyp was attempted using a snare-technique. Following amputation of the polyp, a broad-based component of the polyp remained. Given its proximal location in the esophagus, we were able to use a snare to pull the broad base of the remaining polyp into the oropharynx and remove it at its origin. Postoperative endoscopy and endoscopic ultrasound confirmed that the polyps were completely removed and the muscular resection bed was hemostatic. Clinically, the patient's symptoms resolved and he encountered no adverse sequela as a result of the operation. CONCLUSION: Giant fibrovascular esophageal polyps are rare benign intraluminal tumors that can lead to obstructive symptoms. Surgical resection is the treatment of choice, and may be possible with an endoscopic approach. An endoscopic snare technique can be used to resect these lesions while minimizing patient morbidity.

BACKGROUND AND AIMS: Per-oral endoscopic myotomy (POEM) has become an accepted treatment for patients with achalasia. Despite its excellent efficacy rate of greater than 80%, a small percentage of patients remain symptomatic after the procedure. Limited data exist as to the best management for recurrence of symptoms after POEM. We present the first international, multicenter experience on the efficacy and safety of a repeat POEM in the management of achalasia. METHODS: Patients who underwent a redo POEM from 15 centers in 9 countries were included in a dedicated registry. Technical success was defined as successful completion of a second myotomy. Clinical success was defined as an Eckardt score of less than or equal to 3 after the second myotomy. Adverse events including anesthesia-related, operative, and postoperative adverse events were recorded. RESULTS: Forty-six patients were included in the study. The average age was 49.3 ± 16.78 years. Twenty (45%) patients were male. The mean pre-redo-POEM Eckardt score was 4.3 ± 2.48. Technical success was achieved in 46 (100%) patients. Clinical success was achieved in 41 patients (85%). The average post-POEM Eckardt score was 1.64 ± 1.67, with a significant difference of 2.58 (P < .00001). Eight patients (17%) had adverse events consisting of procedural bleeding, all managed endoscopically. There were no deaths. No POEMs were aborted or required surgical conversion or assistance. DISCUSSION: For patients with persistent symptoms after POEM, repeat POEM appears to be an efficacious and safe technique. Further randomized trials comparing redo POEM versus Heller should be considered. (Clinical trial registration number: NCT02162589.).

INTRODUCTION: Feeding jejunostomies (J tubes) provide enteral nutrition when oral and gastric routes are not options. Despite their prevalence, there is a paucity of literature regarding their efficacy and clinical burden. METHODS: All laparoscopic J tubes placed over a 5-year period were retrospectively reviewed. Clinical burden was measured by number of clinical contact events (tube-related clinic visits, phone calls, ED visits) and morbidity (dislodgement, clogging, tube fracture, infection, other). Tube replacements were also recorded. RESULTS: One hundred fifty-one patients were included. Fifty-nine percent had associated malignancy, and 35 % were placed for nutritional prophylaxis. Mean time to J tube removal was 146 days. J tubes were expected to be temporary in >90 % but only 50 % had sufficient oral intake for removal. Tubes were removed prematurely due to patient intolerance in 8 %. Mortality was 0 %. Morbidity was 51 % and included clogging (12 %), tube fracture (16 %), dislodgement (25 %), infection (18 %) and "other" (leaking, erosion, etc.) in 17 %. The median number of adverse events per J tube was 2(0-8). Mean number of clinic phone calls was 2.5(0-22), ED visits 0.5(0-7), and clinic visits 1.4(0-13), with 82 % requiring more than one J tube-related clinic visit. Unplanned replacements occurred in 40 %. CONCLUSION: While necessary for some patients, J tubes are associated with high clinical burden.

INTRODUCTION: Zenker's diverticulum (ZD) is a rare upper esophageal pathology that is most prevalent in the sixth and seventh decade. Three different therapeutical options are available: (1) open trans-cervical approach, (2) rigid endoscopy and (3) flexible endoscopy. Our hypothesis is that a flexible endoscopic cricomyotomy represents a safe and effective treatment of ZD as well as cricopharyngeal spasm. METHODS: A retrospective analysis of all patients that underwent a flexible endoscopic cricomyotomy at our institution between October 2008 and May 2014 was performed. Preoperative and postoperative (1 month and long-term follow-up) symptom scores and clinical outcomes were collected. Briefly, the ZD is carefully identified endoscopically and the common wall is divided using needle knife cautery with the help of an endoscopic cap. Clips are used to close the mucosal defect starting with the apex. RESULTS: Twenty-six patients underwent a flexible endoscopic myotomy for a ZD. Of 26 patients, five (19.2 %) had a history of previous open or stapled trans-oral myotomy and four (15.4 %) underwent a concomitant foregut procedure. Mean length of stay was 1.5 days (range 1-11). Mean operative time was 68 min (range 28-149). One patient presented with a postoperative leak, and one patient presented with a retained clip. Both were treated endoscopically. Recurrent weekly dysphagia was present in 3/26 (11.5 %). One patient (3.8 %) underwent an endoscopic bougie dilatation postoperatively. With regard to clinical outcomes, there was a statistically significant improvement in both short-term (1 month) and long-term (median follow-up 21.8 months; range 1-68.2 months) dysphagia (p < 0.001; p < 0.001), regurgitation (p = 0.001; p = 0.017), cough (p = 0.006; p = 0.025) and aspiration (p = 0.013; p = 0.013). CONCLUSION: Flexible endoscopic cricomyotomy offers durable relief of dysphagia, regurgitation, cough and aspiration in ZD patients. It appears to have a good safety profile with symptomatic recurrence occurring in up to 11.5 % of cases.

INTRODUCTION: Surgical options for symptomatic delayed gastric emptying include gastric stimulator implantation, subtotal gastrectomy, and pyloroplasty. Pyloroplasty has been shown to improve gastric emptying yet is seldom described as a primary treatment for gastroparesis. We present a single-institution experience of laparoscopic Heineke-Mikulicz pyloroplasty (LP) as treatment for gastroparesis. METHODS AND PROCEDURES: A prospective foregut surgery database was queried for LP over a 5-year period. Charts were reviewed for indications, complications, symptom score, and outcomes. Gastroparesis was defined by (1) abnormal gastric emptying study, (2) endoscopic visualization of retained food after prolonged NPO status, or (3) clinical symptoms suspicious of vagal nerve injury following complex re-operative foregut surgery. Results were analyzed using a paired T test and single-factor ANOVA. RESULTS: One hundred and seventy-seven LP patients were identified and reviewed. One hundred and five had a concurrent fundoplication for objective reflux. There were no intraoperative complications or conversions to laparotomy. Overall morbidity rate was 6.8% with four return to OR and two confirmed leaks (1.1% leak rate). Average length of stay was 3.5 days, and readmission rate was 7%. Eighty-six percent had improvement in GES with normalization in 77%. Gastric emptying half-time decreased from 175 ± 94 to 91 ± 45 min. Nineteen patients (10.7%) had subsequent surgical interventions: gastric stimulator implantation (12), feeding jejunostomy and/or gastrostomy tube (6), or subtotal gastrectomy (4). Symptom severity scores for nausea, vomiting, bloating, abdominal pain, and early satiety decreased significantly at 3 months. CONCLUSION: Laparoscopic pyloroplasty improves or normalizes gastric emptying in nearly 90% of gastroparesis patients with very low morbidity. It significantly improves symptoms of nausea, vomiting, bloating, and abdominal pain. Some patients may go on to another surgical treatment for GP, but it remains a safe and less invasive alternative to a subtotal gastrectomy in these clinically challenging patients.

INTRODUCTION: Obtaining an adequate mucosal closure is one of the crucial steps in per-oral endoscopic myotomy (POEM). Thus far, there have been no objective data comparing the various available closure techniques. This case-controlled study attempts to compare the application of endoscopic clips versus endoscopic suturing for mucosotomy closure during POEM cases. METHODS: A retrospective review of our prospective POEM database was performed. All cases in which endoscopic suturing was used to close the mucosotomy were matched to cases in which standard endoclips were used. Overall complication rate, closure time and mucosal closure costs between the two groups were compared. RESULTS: Both techniques offer good clinical results with good mucosal closure and the absence of postoperative leak. Closure time was significantly shorter (p = 0.044) with endoscopic clips (16 ± 12 min) when compared to endoscopic suturing (33 ± 11 min). Overall, the total closure cost analysis showed a trend toward lower cost with clips (1502 ± 849 USD) versus endoscopic suturing (2521 ± 575 USD) without reaching statistical significance (p = 0.073). CONCLUSION: The use of endoscopic suturing seems to be a safe method for mucosal closure in POEM cases. Closure time is longer with suturing than conventional closure with clips, and there is a trend toward higher overall cost. Endoscopic suturing is likely most cost-effective for difficult cases where conventional closure methods fail.

BACKGROUND: Roux-en-Y gastric bypass (RYGB) is considered to be an optimal surgical treatment option for GERD in the morbidly obese patient. Nevertheless, a subgroup of patients suffer from recurrent or persistent GERD after their gastric bypass. Unfortunately, limited treatment options are available in these patients. Fundoplication via mobilization of the remnant stomach and radiofrequency treatment of the lower esophageal sphincter have been described with some success. Our objective is to illustrate a safe and durable surgical option in the treatment of patients with medically refractory GERD post-RYGB. METHODS: After placing five trocars in the usual position for a foregut laparoscopic surgery, a lysis of adhesions and standard dissection of the hiatus is performed. The anterior and posterior vagal nerves associated phrenoesophageal tissue bundles are identified. A primary crural repair with interrupted nonabsorbable sutures is performed. Four full-length nonabsorbable sutures are placed sequentially through the anterior and posterior phrenoesophageal bundle, posterior fundus and finally through the pre-aortic fascia. The repair is calibrated on a 44 French bougie. The sutures are tied from medial to lateral in the order of their placement under endoscopic guidance. RESULTS: No peri-procedural complications were encountered. Standard post-antireflux surgery clinical follow-up with the patient completing a validated GERD clinical questionnaire at 1 and 6 months after the surgery demonstrated excellent GERD symptom control without any dysphagia. A pH study and EGD performed at 6 months post-Hill procedure show the absence of pathological reflux with an intact Hill mechanism. CONCLUSION: The Hill procedure is a valid treatment for the post-bariatric surgical patient with GERD in which the gastric fundus is absent or inaccessible thus eliminating standard fundoplication as a reasonable option. This also represents a safe and durable treatment of GERD in this uniquely challenging patient population.
