Postoperative Dysphagia Following Esophagogastric Fundoplication: Does the Timing to First Dilation Matter?

Background Postoperative dysphagia after anti-reflux surgery typically resolves in a few weeks. However, even after the initial swelling has resolved at 6 weeks, dysphagia can persist in 30% of patients necessitating esophageal dilation. The purpose of this study was to investigate the effect of esophageal dilation on postoperative dysphagia, the recurrence of reflux symptoms, and the efficacy of pneumatic dilations on postoperative dysphagia. Methods A prospectively collected database was reviewed for patients who underwent partial/complete fundoplication with/without paraesophageal hernia repair between 2006 and 2014. Patient age, sex, BMI, DeMeester score, procedure type, procedure duration, length of stay, postoperative dysphagia, time to first pneumatic dilation, number of dilations, and the need for reoperations were collected. Results The study included 902 consecutive patients, 71.3% females, with a mean age of 57.8 ± 14.7 years. Postoperative dysphagia was noted in 26.3% of patients, of whom 89% had complete fundoplication (p < 0.01). Endoscopic dilation was performed in 93 patients (10.3%) with 59 (63.4%) demonstrating persistent dysphagia. Recurrent reflux symptoms occurred in 35 (37.6%) patients who underwent endoscopic dilation. Patients who underwent a dilation for symptoms of dysphagia were less likely to require a revisional surgery later than patients who had dysphagia but did not undergo a dilation before revisional surgery (17.2% vs 41.7%, respectively, p < 0.001) in the 4-year follow-up period. The duration of initial dilation from surgery was inversely related to the need for revisional surgery (p = 0.047), while more than one dilation was not associated with additive benefit. Conclusion One attempt at endoscopic dilation of the esophagogastric fundoplication may provide relief in patients with postoperative dysphagia and can be used as a predictive factor for the need of revision. However, there is an increased risk for recurrent reflux symptoms and revisional surgery may ultimately be indicated for control of symptoms

High Rates of Nicotine Use Relapse and Ulcer Development Following Roux-en-Y Gastric Bypass

PURPOSE: Given that smoking is known to contribute to gastrojejunal anastomotic (GJA) ulcers, cessation is recommended prior to laparoscopic Roux-en-Y gastric bypass (LRYGB). However, smoking relapse rates and the exact ulcer risk remain unknown. This study aimed to define smoking relapse, risk of GJA ulceration, and complications after LRYGB. MATERIALS AND METHODS: We performed a retrospective cohort study of patients who underwent primary LRYGB during 2011-2015. Initially, three patient categories were identified: lifetime non-smokers, patients who were smoking during the initial visit at the bariatric clinic or within the prior year (recent smokers), and patients who had ceased smoking more than a year prior to their initial clinic visit (former smokers). Smoking relapse, GJA ulcer occurrences, reinterventions, and reoperations were recorded and compared. RESULTS: A total of 766 patients were included in the analysis. After surgery, 53 (64.6%) recent smokers had resumed smoking. Out of these relapsed smokers, 51% developed GJA ulcers compared with 14.8% in non-relapsed recent smokers, 16.1% in former smokers, and 6% in lifetime nonsmokers (p < 0.001). Furthermore, relapsed smokers required more frequently endoscopic reinterventions (60.4%) compared with non-relapsed smokers (20.8%, p < 0.001), former smokers (20.7%, p < 0.001), and lifetime non-smokers (15.4%, p < 0.001). Additionally, relapsed smokers required a reoperation (18.9%) more often than non-relapsed recent smokers (5.7%, p < 0.001) and lifetime non-smokers (1.3%, p < 0.001). CONCLUSION: Smokers relapse frequently after LRYGB, and the majority experience GJA complications. They should be counseled about this risk preoperatively and directed towards less ulcerogenic procedures when possible. Alternatively, longer periods of preoperative smoking abstinence might be needed

How are Bariatric Patients Coping During the COVID-19 Pandemic? Analysis of Factors Known to Cause Weight Regain Among Postoperative Bariatric Patients

Background The global coronavirus disease 2019 (COVID-19) pandemic is wreaking havoc on society. Bariatric patients are more prone to severe infection due to their high body mass index (BMI) and are more vulnerable to the effects of isolation, such as depression or disruption of their health habits. Objectives To quantify the impact of self-quarantine on bariatric patients and self-quarantine’s relationship with weight gain. Setting Academic hospital, United States. Methods A 30-item survey examining several known contributors to weight regain was distributed among the postoperative bariatric patients of our clinic. Changes in eating habits, exercise, depression, social support, loneliness, and anxiety were studied, among others. Results A total of 208 patients completed the survey (29.3% response rate). A large percentage of patients reported increases in their depression (44.2%), loneliness (36.2%), nervousness (54.7%), snacking (62.6%), loss of control when eating (48.2%), and binge eating (19.5%) and decreases in their social support (23.2%), healthy food eating (45.5%), and activity (55.2%). Difficulty in accessing vitamins was reported by 13%. Patients more than 18 months out of surgery regained more than 2 kg during an average of 47 days. Risk factors for weight regain were found to be loss of control when eating, increases in snacking and binge eating, reduced consumption of healthy food, and reduced physical activity. Conclusion Bariatric patients are negatively affected by the COVID-19 pandemic and subsequent social isolation on many levels. This patient population is vulnerable to crisis situations; thus, additional intervention is needed to address behaviors that lead to weight regain

What delays your case start? Exploring operating room inefficiencies

Introduction Improving operating room (OR) inefficiencies benefits the OR team, hospital, and patients alike but the available literature is limited. Our goal was, using a novel surgical application, to identify any OR incidents that cause delays from the time the patient enters the OR till procedure start (preparatory phase). Materials and methods We conducted an IRB approved, prospective, observational study between July 2018 and January 2019. Using a novel surgical application (ExplORer Surgical) three observers recorded disrupting incidents and their duration during the preparatory phase of a variety of general surgery cases. Specifically, the number and duration of anesthesia delays, unnecessary/distracting conversations, missing items, and other delays were recorded from the moment they started until they stopped affecting the normal workflow. Results Ninety-six OR cases were assessed. 20 incidents occurred in 18 (19%) of those cases. The average preparatory duration for all the cases was 20.7 ± 8.6 min. Cases without incidents lasted 19.5 ± 7.4 min while cases with incidents lasted 25.9 ± 11.2 min, p = 0.03. The average incident lasted 3.7 min, approximately 18% of the preparatory phase duration. Conclusion The use of the ExplORer Surgical app allowed us to accurately record the incidents happening during the preparatory phase of various general surgery operations. Such incidents significantly prolonged the preparatory duration. The identification of those inefficiencies is the first step to targeted interventions that may eventually optimize the efficiency of preoperative preparation

Surgical Outcomes in Syndromic Tetralogy of Fallot: A Systematic Review and Evidence Quality Assessment

Tetralogy of Fallot (ToF) is one of the most common cyanotic congenital heart defects. We sought to summarize all available data regarding the epidemiology and perioperative outcomes of syndromic ToF patients. A PRISMA-compliant systematic literature review of PubMed and Cochrane Library was performed. Twelve original studies were included. The incidence of syndromic ToF was 15.3% (n = 549/3597). The most prevalent genetic syndromes were 22q11.2 deletion (47.8%; 95% CI 43.4–52.2) and trisomy 21 (41.9%; 95% CI 37.7–46.3). Complete surgical repair was performed in 75.2% of the patients (n = 161/214; 95% CI 69.0–80.1) and staged repair in 24.8% (n = 53/214; 95 CI 19.4–30.9). Relief of RVOT obstruction was performed with transannular patch in 64.7% (n = 79/122; 95% CI 55.9–72.7) of the patients, pulmonary valve-sparing technique in 17.2% (n = 21/122; 95% CI 11.5–24.9), and RV-PA conduit in 18.0% (n = 22/122; 95% CI 12.1–25.9). Pleural effusions were the most common postoperative complications (n = 28/549; 5.1%; 95% CI 3.5–7.3). Reoperations were performed in 4.4% (n = 24/549; 95% CI 2.9–6.4) of the patients. All-cause mortality rate was 9.8% (n = 51/521; 95% CI 7.5–12.7). Genetic syndromes are seen in approximately 15% of ToF patients. Long-term survival exceeds 90%, suggesting that surgical management should be dictated by anatomy regardless of genetics

Chylous ascites in the setting of internal hernia: a reassuring sign

BACKGROUND: Chylous ascites is often reported in cases with lymphatic obstruction or after lymphatic injuries such as intraabdominal malignancies or lymphadenectomies. However, chylous ascites is also frequently encountered in operations for internal hernias. We sought to characterize the frequency and conditions when chylous ascites is encountered in general surgery patients. METHODS: Data from patients who underwent operations for CPT codes related to open and laparoscopic abdominal and gastrointestinal surgery in our tertiary hospital from 2010 to 2019 were reviewed. Patients with the postoperative diagnosis of internal hernia were identified and categorized into three groups: Internal Hernia with chylous ascites, non-chylous ascites, and no ascites. Demographics, prior surgical history, CT findings, source of internal hernia, open or laparoscopic surgery, and preoperative labs were recorded and compared. RESULTS: Fifty-six patients were found to have internal hernias and were included in our study. 80.3% were female and 86% had a previous Roux-en-Y gastric bypass procedure (RYGBP). Laparoscopy was the main approach for all groups. Ascites was present in 46% of the cases. Specifically, chylous ascites was observed in 27% of the total operations and was exclusively (100%) found in patients with gastric-bypass history. Furthermore, it was more commonly associated with Petersen's defect (p < 0.001), while the non-chylous fluid group was associated with herniation through the mesenteric defect (p < 0.001). CONCLUSIONS: Chylous ascites is a common finding during internal hernia operations. Unlike other more morbid conditions, identification of chylous ascites during an internal hernia operation appears innocuous. However, in the context of a patient with a history of RYGBP, the presence of chylous fluid signifies the associated small bowel obstruction is likely related to an internal hernia through a patent Petersen's defect

How resilient is your team? Exploring healthcare providers’ well-being during the COVID-19 pandemic

Background: The global COVID-19 pandemic has placed tremendous physical and mental strain on the US healthcare system. Studies examining the effects of outbreaks have demonstrated both an increased prevalence and long-term development of Post-Traumatic Stress Disorder (PTSD) symptoms in healthcare providers. We sought to assess the impact of the COVID-19 pandemic on the psychological well-being of medical providers, medical trainees, and administrators at a large academic center to identify stressors and moderators to guide future mental health and hospital-system interventions. Methods: A 42-item survey examining specific stressors, grit, and resilience was widely distributed to physicians, residents, fellows, and administrators a large academic institution for departmental distribution. Survey results were analyzed using descriptive statistics, ANOVA, and multivariate linear regressions. A p-value <0.05 was considered statistically significant. Results: A total of 785 participants completed the survey. The majority of respondents rated their stress to be significantly increased during the pandemic. Respondents’ fear of transmitting the virus to their family members was a significant stressor. Higher resilience was associated with lower stress, anxiety, fatigue, and sleep disturbances. Overall, respondents felt supported by their departments and institution and felt contingency plans and personal protective equipment were adequate. Conclusions: Healthcare workers have increased resilience in the face of heightened stress during a pandemic. Higher resilience and grit were protective factors in managing personal and system-level stressors at the peak of the COVID-19 pandemic in our institution. Implementing an intervention designed to enhance healthcare workers’ resilience in response to the COVID-19 pandemic is warranted

Evaluation of the Efficacy and Synergistic Effect of α- and δ-Tocopherol as Natural Antioxidants in the Stabilization of Sunflower Oil and Olive Pomace Oil during Storage Conditions

Tocopherols are natural bioactive compounds with several health benefits. This study evaluated the effect of different ratios of α- and δ- tocopherol homologs to protect sunflower oil (SO) and olive pomace oil (OPO) against oxidation. A synergistic effect was recorded when the two tocopherols were combined at a ratio of 7:1 (α-T/δ-T). The oil samples were exposed to accelerated oxidation conditions using a Rancimat (90 °C and airflow of 15 L/h for 24 h) and protection from tocopherols was compared with that from butylated hydroxytoluene (BHT). Assessment of oil stability was examined using well-known parameters such as peroxide value (PV), thiobarbituric acid reactive substances (TBARS), p-anisidine value (p-AV), conjugated dienes (CD) and trienes (CT), and total oxidation (Totox) value, which were all significantly reduced when tocopherols were added at a ratio of 7:1 α-T/δ-T. Primary oxidative compounds measured according to PV were only reduced in SO samples (6.11%). Off-flavor compounds measured via TBARS assay in SO samples were reduced by above 20%, while p-AV was also reduced. CDvalue was correlated with PV in SO samples, while the 7:1 mixture was more effective than BHT for CTvalue. Total oxidation values in SO samples and OPO samples were reduced by 6.02% and 12.62%, respectively. These values in SO samples also provided a remarkable correlation (R2 > 0.95) with incubation time. Moreover, the synergistic effect was not only effective in reducing the oxidation values of oil samples, but also in lowering the degradation rate of tocopherols. Protective effects from tocopherols were mainly observed in SO samples, as OPO samples were more resistant to oxidation processes. This effect was even observed in fatty acid analysis, where the 7:1 mixture provided better results than BHT-spiked samples. Thus, it is suggested that tocopherol mixtures might be used as a natural preservative in the food industry to restrain lipid oxidation processes

Post-thyroidectomy Hypocalcemia in Patients With History of Bariatric Operations: Current Evidence and Management Options

BACKGROUND/AIM: Both bariatric and thyroid surgeries promote calcium and vitamin D deficiency. The correlation, however, of hypocalcemia after thyroidectomy in patients with previous bariatric surgery has been poorly described. This review aimed to investigate the relationship between history of bariatric operations and post-thyroidectomy hypocalcemia, as well as suggested management options. MATERIALS AND METHODS: MEDLINE and Cochrane databases were searched for relevant publications regarding post-thyroidectomy hypocalcemia in patients with previous bariatric surgery. RESULTS: A total of 17 publications reporting on 126 patients met the inclusion criteria. These included 13 publications about Roux-en-Y gastric bypass (RYGB), 2 regarding biliopancreatic diversion (BPD), 1 about sleeve gastrectomy (SG) and 1 compared three bariatric procedures: SG, RYGB, laparoscopic adjustable gastric band (LAGB). Post-thyroidectomy hypocalcemia was found to be more prevalent in patients with previous RYGB and BPD, but not in previous LAGB and SG. CONCLUSION: Patients with previous bariatric surgery are at high risk of post-thyroidectomy hypocalcemia that sometimes leads to higher length of hospital stay and demands more invasive solutions. There is a need, however, for additional studies and further investigation in order to reach more conclusive results
