The Impact of Ineffective Esophageal Motility on Patients Undergoing Magnetic Sphincter Augmentation.

OBJECTIVE: To evaluate and characterize outcomes of MSA in patients with IEM. SUMMARY BACKGROUND DATA: MSA improves patients with gastroesophageal reflux and normal motility. However, many patients have IEM, which could impact the outcomes of MSA and discourage use. METHODS: An international, multi-institutional case control study of IEM patients undergoing MSA matched to normal patients was performed. Primary outcomes were new onset dysphagia and need for postoperative interventions. RESULTS: A total of 105 IEM patients underwent MSA with matching controls. At 1 year after MSA: GERD-Health Related Quality of Life was similar; DeMeester scores in IEM patients improved to 15.7 and 8.5 in controls ( P = 0.021); and normalization of the DeMeester score for IEM = 61.7% and controls = 73.1% ( P = 0.079).In IEM patients, 10/12 (83%) with preop dysphagia had resolution; 11/66 (17%) had new onset dysphagia and 55/66 (83%) never had dysphagia. Comparatively, in non-IEM patients, 22/24 (92%) had dysphagia resolve; 2/24 (8%) had persistent dysphagia; 7/69 (10%) had new onset dysphagia, and 62/69 (90%) never had dysphagia.Overall, 19 (18%) IEM patients were dilated after MSA, whereas 12 (11%) non-IEM patients underwent dilation ( P = 0.151). Nine (9%) patients in both groups had their device explanted. CONCLUSIONS: Patients with IEM undergoing MSA demonstrate improved quality of life and reduction in acid exposure. Key differences in IEM patients include lower rates of objective GERD resolution, lower resolution of existing dysphagia, higher rates of new onset dysphagia and need for dilation. GERD patients with IEM should be counselled about these possibilities.

The Nissen-Hill Hybrid Repair: Experience With the First 500.

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.

Morbidity and mortality after antireflux and hiatal hernia surgery across a spectrum of ages.

BACKGROUND: Antireflux surgery (ARS) and hiatal hernia repair (HHR) are common surgical procedures with modest morbidity. Increasing age is a risk factor for complications; however, details regarding acute morbidity are lacking. This study aimed to describe the incidence rates and types of morbidities across the spectrum of ages. METHODS: A total of 2342 consecutive cases were retrospectively reviewed from 2003 to 2020 for 30-day complications. All complications were assessed using the Clavien-Dindo (CD) grading system. Patients were divided into 5 age groups: ≤59, 60 to 69, 70 to 79, 80 to 89, and ≥90 years. RESULTS: The numbers per age group were 1100 patients aged ≤59 years, 684 patients aged 60 to 69 years, 458 patients aged 70 to 79 years, 458 patients aged 80 to 89 years, and 6 patients aged ≥90 years. A total of 427 complications (18.2%) occurred, including 2 mortalities, each in the 60- to 69-year age group and the 70- to 79-year age group, for a mortality rate of 0.2%. The complication rate increased from 13.5% (149) in patients aged ≤59 years to 35.0% (35) in patients aged ≥80 years (P = .006), with CD grades I and II accounting for >70% of complications, except in patients aged ≥80 years (57.1%). CD grades IIIa and IIIb were higher in patients aged ≥80 years (26.5% [P = .001] and 11.8% [P = .021], respectively). CD grade IVa and IVb complications were rare overall. CONCLUSION: There is a modest rate of morbidity that increases as patients age, regardless of hernia type, elective or primary surgery, with most being minor complications (CD grade≤II). Our data should help patients, referring physicians, and surgeons counsel patients regarding the effect of increasing age in ARS and HHR.

Choledochal cysts: Similarities and differences between Asian and Western countries.

Choledochal cysts (CCs) are rare bile duct dilatations, intra-and/or extrahepatic, and have higher prevalence in the Asian population compared to Western populations. Most of the current literature on CC disease originates from Asia where these entities are most prevalent. They are thought to arise from an anomalous pancreaticobiliary junction, which are congenital anomalies between pancreatic and bile ducts. Some similarities in presentation between Eastern and Western patients exist such as female predominance, however, contemporary studies suggest that Asian patients may be more symptomatic on presentation. Even though CC disease presents with an increased malignant risk reported to be more than 10% after the second decade of life in Asian patients, this risk may be overstated in Western populations. Despite this difference in cancer risk, management guidelines for all patients with CC are based predominantly on observations reported from Asia where it is recommended that all CCs should be excised out of concern for the presence or development of biliary tract cancer.
