Strategies for surgical remediation of the multi-fundoplication failure patient.

BACKGROUND: Outcomes are not well studied in patients undergoing remediation for multi-fundoplication failure, that is, two or more prior failed fundoplications. Re-operation must balance reflux control and restoration of the ability to eat with the challenge of reconstructing a distorted hiatus and GE junction. The purpose of this study is to present our experience with surgical remediation for multi-fundoplication failure. METHODS: Medical records were retrospectively reviewed of 91 patients who underwent third time or more esophagogastric operation for fundoplication failure at a single institution from 2007 to 2016. Dysphagia was present in 56% and heartburn in 51%. Median number of prior operations was 2 with range up to 6. Anatomic failure consisted of slipped wrap in 26 cases, wrap herniation in 23, hiatal stenosis in 24, hiatal mesh complication in 8, and wrap dehiscence in 10. Operative approaches generally followed an institutional algorithm and consisted of hiatal hernia repair with: re-do fundoplication in 55%, takedown of fundoplication alone in 24%, Roux-en-Y gastrojejunostomy in 14%, and GE junction resection in 7%. Laparoscopic approach was successful in 81%. RESULTS: Mean duration of operations was 217 min and median length of stay was 3 days. The complication rate was 13%, with 7% undergoing unplanned early re-operation. Patients were followed for mean 11 months, and recurrent hiatal hernia was detected in 13%. Late re-operation was performed in 6% for recurrent hiatal hernia. Recurrent reflux symptomatology resolved in 93%. Dysphagia resolved in 84%. There were no significant differences in outcomes with regard to number of prior operations, operative approach, BMI, or age. CONCLUSIONS: There is no single best approach to remediation in the multi-fundoplication failure patient. Re-do fundoplication is appropriate in over half of patients. Reoperation for multi-fundoplication failure can be performed via minimally invasive approach with excellent remediation of symptoms, low morbidity, and low recurrence rates.

Laparoscopic repair of giant paraesophageal hernia: are there factors associated with anatomic recurrence?

BACKGROUND: Repair of giant paraesophageal hernia (PEH) is associated with a favorably high rate of symptom improvement; however, rates of recurrence by objective measures remain high. Herein we analyze our experience with laparoscopic giant PEH repair to determine what factors if any can predict anatomic recurrence. METHODS: We prospectively collected data on PEH characteristics, variations in operative techniques, and surgeon factors for 595 patients undergoing laparoscopic PEH repair from 2008 to 2015. Upper GI study was performed at 6 months postoperatively and selectively thereafter-any supra-diaphragmatic stomach was considered hiatal hernia recurrence. Exclusion criteria included revisional operation (22.4%), size <5 cm (17.6%), inadequate follow-up (17.8%), and confounding concurrent operations (6.9%). Inclusion criteria were met by 202 patients (31% male, median age 71 years, and median BMI 28.7). RESULTS: At a median follow-up of 6 months (IQR 6-12), overall anatomic recurrence rate was 34.2%. Symptom recurrence rate was 9.9% and revisional operation was required in ten patients (4.9%). Neither patient demographics nor PEH characteristics (size, presence of Cameron erosions, esophagitis, or Barrett's) correlated with anatomic recurrence. Technical factors at operation (mobilized intra-abdominal length of esophagus, Collis gastroplasty, number of anterior/posterior stitches, use of crural buttress, use of pledgeted or mattress sutures, or gastrostomy) were also not correlated with recurrence. Regarding surgeon factors, annual volume of fewer than ten cases per year was associated with increased risk of anatomic failure (54 vs 33%, P = 0.02). Multivariate analysis identified surgeon experience (<10 cases per year) as an independent factor associated with early hiatal hernia recurrence (OR 3.7, 95% CI 1.34-10.9). CONCLUSIONS: Laparoscopic repair of giant PEH is associated with high anatomic recurrence rate but excellent symptom control. PEH characteristics and technical operative variables do not appear to significantly affect rates of recurrence. In contrast, surgeon volume does appear to contribute significantly to durability of repair.

Feasibility of implementing a virtual reality program as an adjuvant tool for peri-operative pain control; Results of a randomized controlled trial in minimally invasive foregut surgery.

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.

Short-Term Outcomes Predict Long-Term Satisfaction in Patients Undergoing Laparoscopic Magnetic Sphincter Augmentation.

INTRODUCTION: Laparoscopic magnetic sphincter augmentation (MSA) has been shown to be efficacious therapy for gastroesophageal reflux disease (GERD) refractory to maximal medical management. Herein, we present our experience with this procedure and an analysis of our outcomes. MATERIALS AND METHODS: Medical records were retrospectively reviewed of 98 patients who underwent laparoscopic MSA for GERD at a single institution from 2012 to 2016. Symptoms were assessed with gastroesophageal reflux disease-health-related quality of life (GERD-HRQL) questionnaire. Objective testing included pH testing, manometry, endoscopy, and upper GI series. Postimplantation interventions were recorded. Median follow-up was 46 months. RESULTS: Median preoperative DeMeester score was 32 (interquartile range 21-46). Esophagitis was present in 18%. Hiatal hernia was present in 59%. Operation required full hiatal dissection in 16%. There were no intraoperative complications. Mean hospital stay postimplantation was 18 hours. Reoperative intervention with device explant was necessary in 5 cases, one of which was for intraluminal device erosion. Median GERD-HRQL scores were 25 preoperatively, 8 in short-term follow-up at median 1 month, and 5 in long-term follow-up at median 46 months. Improvement in GERD-HRQL scores was statistically significant with both short and long term compared with preoperative (P < .05), but no different between short- and long-term follow-up. Daily bothersome dysphagia was present in 19 patients preoperatively and in 9 at long-term follow-up. CONCLUSIONS: Laparoscopic MSA is associated with excellent outcomes with decrease in GERD-HRQL scores in short term that are durable to longer term follow-up, and with low rates of new-onset dysphagia.

Examination of unplanned 30-day readmissions to a comprehensive cancer hospital.

PURPOSE: The Centers for Medicare and Medicaid Services (CMS), under the Hospitals Readmissions Reductions Program, may withhold regular reimbursements for excessive 30-day readmissions for select diagnoses. Such penalties imply that some readmissions reflect poor clinical decision making or care during the initial hospitalization. We examined factors related to potentially preventable readmissions in CMS patients at a tertiary cancer hospital. METHODS: The medical records of all CMS patients with unplanned readmissions within 30 days of index admission were reviewed over 6 months (October 15, 2011-April 15, 2012). Each readmission was classified as not preventable or potentially preventable. Factors associated with potentially preventable readmissions were sought. RESULTS: Of 2,531 inpatient admissions in CMS patients over 6 months, 185 patients experienced at least one readmission for 282 total readmissions (11%). Median time to readmission was 9 days (range, 0 to 30 days). The most common causes for first readmission were new diagnoses not present at first admission (n = 43, 23%), new or worsening symptoms due to cancer progression (n = 40, 21%) and complications of procedures (n = 25, 13%). There were 38 (21%) initial readmissions classified as potentially preventable. Use of total parenteral nutrition at the time of discharge was associated with potentially preventable readmission (P = .028). CONCLUSION: Most unplanned readmissions to a tertiary cancer hospital are related to progression of disease, new diagnoses, and procedure complications. Minimizing readmissions in complex cancer patients is challenging. Larger multi-institutional datasets are needed to determine a reasonable standard for expected readmission rates.

Evaluation of a new 240-µm single-use holmium:YAG optical fiber for flexible ureteroscopy.

BACKGROUND AND PURPOSE: Numerous holmium:yttrium-aluminum-garnet laser fibers are available for flexible ureteroscopy. Performance and durability of fibers can vary widely among different manufacturers and their product lines with differences within a single product line have been reported. We sought to evaluate a newly developed nontapered, single-use 240-µm fiber, Flexiva™ 200 (Boston Scientific, Natick, MA), during clinical use and in a bench-testing model. MATERIALS AND METHODS: A total of 100 new fibers were tested after their use in 100 consecutive flexible ureteroscopic lithotripsy procedures by a single surgeon (B.K.). Prospectively recorded clinical parameters were laser pulse energy and frequency settings, total energy delivered and fibers failure. Subsequently, each fiber was bench-tested using an established protocol. Parameters evaluated for were fibers true diameter, flexibility, tip degradation, energy transmission in straight and 180° bend configuration and fibers failure threshold with stress testing. RESULTS: The mean total energy delivered was 2.20 kJ (range 0-18.24 kJ) and most common laser settings used were 0.8 J at 8 Hz, 0.2 J at 50 Hz, and 1.0 J at 10 Hz, respectively. No fiber fractured during clinical procedures. The true fiber diameter was 450 µm. Fiber tips burnt back an average of 1.664 mm, but were highly variable. With laser setting of 400 mJ at 5 Hz, the mean energy transmitted was 451 and 441 mJ in straight and 180° bend configuration, respectively. Thirteen percent of fibers fractured at the bend radius of 0.5 cm with a positive correlation to the total energy transmitted during clinical use identified. CONCLUSION: Fiber performance was consistent in terms of energy transmission and resistance to fracture when activated in bent configuration. Fiber failure during stress testing showed significant correlation with the total energy delivered during the clinical procedure. The lack of fiber fracture during clinical use may reduce the risk of flexible endoscope damage due to fiber failure.
