RESUMO
BACKGROUND: Bariatric surgery can improve renal function in patients with comorbid chronic kidney disease (CKD) and obesity. Additionally, bariatric surgery can enhance outcomes following renal transplantation. The safety of bariatric surgery in patients with CKD has been debated in the literature. This study evaluates the frequency of perioperative complications associated with CKD. METHODS: The Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database was queried from 2015-2019. Patients were included if they had a vertical sleeve gastrectomy (VSG) or Roux-en-Y gastric bypass (RYGB) and were stratified based on CKD status. An unmatched and propensity-matched analysis was performed comparing 30-day perioperative outcomes between the groups. RESULTS: A total of 717,809 patients included in this study, 5817(0.8%) had CKD, of whom 2266(0.3%) were on dialysis. 74.3% of patients with CKD underwent VSG with 25.7% underwent RYGB. Comparing RYGB to VSG, patients who underwent RYGB had a higher rate of deep organ space infection (0.7%vs.0.1%,p = 0.021) and re-intervention (5.0% vs. 2.2%,p < 0.001). Within the VSG cohort, a matched analysis was performed for those with CKD and without CKD. The CKD cohort had higher risk of complications such as bleeding (2.1%vs. 0.9%,p < 0.001), readmission (9.3%vs.4.9%,p < 0.001), reoperation (2.7%vs.1.3%,p < 0.001), and need for reintervention (2.2%vs.1.3%,p < 0.001). Notably, patients with CKD also had a higher mortality (0.6%vs.0.2%,p = 0.003). No difference was seen between patients with renal insufficiency and patients on dialysis. CONCLUSION: VSG has been the operation of choice in patients with CKD. Our results showed it is the safer option for patients with CKD compared to RYGB. Although this patient population does have an increased risk of adverse perioperative events, dialysis didn't affect the outcome. Bariatric surgeons who operate on patients with CKD should be well informed and remain vigilant given the increased perioperative risk. The risk is still considerably low, and the potential benefit on renal function and improvement in candidacy for renal transplant outweigh the risk. They should be considered as surgical candidates.

BACKGROUND: Vertical sleeve gastrectomy (VSG) has demonstrated to be safe; however, controversy remains on how to decrease major complications, particularly bleeding and leaks. There are variations in staple-line reinforcement techniques, including no reinforcement, oversewing, and buttressing. We sought to evaluate the effect of those methods on post-operative complications using the Metabolic and Bariatric Surgery Accreditation Quality Initiative Program (MBSAQIP) database. METHODS: The MBSAQIP was queried for patients who underwent VSG during 2015-2019. A propensity-matched analysis was performed between different staple-line reinforcement (SLR) methods, specifically No reinforcement (NR), Oversewing (OS), and Buttressing (BR). The primary outcome of interest was complications within 30 days. RESULTS: A total of 513,354 VSG cases were analyzed. The cohort was majority female (79.0%), with mean (SD) age of 44.2 ± 11.9 years and mean BMI of 45 ± 7.8 kg/m2. Frequency of SLR methods used was 54%BR, 25.6%NR, 10.8% BR + OS, and 9.8%OS. There were no differences in rate of leaks among SLR methods. Compared to NR, BR was associated with decreased rate of reoperations, overall bleeding, and major bleeding (p < 0.05) but prolonged operative time and length of stay (LOS) (p < 0.05). OS was associated with decreased overall bleeding (p < 0.05) but prolonged operative times and length of stay (p < 0.05) compared to NR. Compared to BR, OS was associated with increased operative times, LOS, and rates of post-operative ventilator use, pneumonia, and venous thrombosis (p < 0.05). Patients with bleeding were associated with lower rate of BR (56% vs 61%) and higher rate of NR (34% vs 28%) compared to patients with no bleeding. Bleeding was associated with a greater frequency of leaks (4.4% vs 0.3%), along with higher morbidity and mortality (p < 0.05). CONCLUSIONS: Of the reinforcement methods evaluated, BR and OS were both associated with decreased bleeding despite longer operative times. No method was found to significantly reduce incidence of leaks; however, bleeding was associated with increased incidence of leaks, morbidity, and mortality. The liberal use of SLR techniques is recommended for further optimization of patient outcomes after VSG.

BACKGROUND: Paraesophageal hernias (PEH) have a higher incidence in patients with obesity. Roux-en-Y gastric bypass (RYGB) with concomitant PEH repair is established as a valid surgical option for PEH management in patients with obesity. The safety and feasibility of this approach in the elderly population are not well elucidated. METHODS: We performed a multicenter retrospective cohort study of patients aged 65 years and older who underwent simultaneous PEH repair and RYGB from 2008 to 2022. Patient demographics, hernia characteristics, postoperative complications, and weight loss data were collected. Obesity-related medical conditions' resolution rates were evaluated at the last follow-up. A matched paired t-test and Pearson's test were used to assess continuous and categorical parameters, respectively. RESULTS: A total of 40 patients (82.5% female; age, 69.2 ± 3.6 years; BMI, 39.4 ± 4.7 kg/m2) with a mean follow-up of 32.3 months were included. The average hernia size was 5.8 cm. Most cases did not require mesh use during surgery (92.5%) with only 3 (7.5%) hernial recurrences. Postoperative complications (17.5%) and mortality rates (2.5%), as well as readmission (2.5%), reoperation (2.5%), and reintervention (0%) rates at 30-day follow-up were reported. There was a statistically significant resolution in gastroesophageal reflux disease (p < 0.001), hypertension (p = 0.019), and sleep apnea (p = 0.014). CONCLUSIONS: The safety and effectiveness of simultaneous PEH repair and RYGB are adequate for the elderly population. Patient selection is crucial to reduce postoperative complications. Further studies with larger cohorts are needed to fully assess the impact of this surgery on elderly patients with obesity.

Neuroleptic malignant syndrome (NMS) is described in the medical literature but rarely seen among acutely ill trauma patients. A 44-year-old man with burns to the hands and back after a chemical explosion was transported to an outside facility where he received treatment for presumed acute coronary syndrome after developing ventricular tachycardia and elevated serum troponins after the exposure. His cardiac catheterization was unremarkable, but an echocardiogram revealed severe cardiomyopathy, and he was also in multisystem organ failure. He was transferred to our facility after hospital day 2 for treatment of his multisystem organ failure and 2% total body surface area burns. His laboratory results were remarkable for a creatine kinase of >100 000 units/L, and he required 14 g of intravenous calcium. Upon further investigation, the patient reported taking ziprasidone for his bipolar disorder, and he had a core temperature of 103.5 °F on his initial presentation to the outside facility. As he convalesced, the unifying diagnosis was NMS. NMS is a side effect of antipsychotic therapy and is manifested by hyperpyrexia, rigidity, autonomic instability, and altered consciousness. An elevated creatine kinase >100 000 units/L is almost pathognomonic for NMS. Patients can also present with leukocytosis, organ failure, and electrolyte disturbances including hypocalcemia. We hypothesized that dehydration, the warm environmental conditions at our patient's job, and immense stress resulting in a catecholamine surge following his trauma were inciting triggers to this event. This case highlights the importance of considering alternate diagnoses in patients whose clinical presentation does not fit the most "obvious cause."

Teratomas are a common form of non-seminomatous germ cell tumor histologically composed of tissues derived from multiple cell lines of the primary embryonic germ cell layers. There are few cases reported in the literature that describe multiple locations with recurrence of benign teratomas, none of which describe an elevated AFP. We describe a case of metachronous bilateral recurrent ovarian and mediastinal teratomas with a curiously elevated α-fetoprotein. We may be describing a novel syndrome of recurrent metachronous teratomas. Because of the uncertainty of this case, the patient will require close follow-up over the next several years.

BACKGROUND: Healthcare disparities have afflicted the healthcare industry for decades and there have been many campaigns in recent years to identify and eliminate disparities. The purpose of this study was to identify disparities in the lung cancer population of a single community cancer center and to report the results in accordance with industry goals. METHODS: This was a retrospective cohort study of data on non-small cell lung cancer patients recorded in the Christiana Care Tumor Registry (CCTR) in Delaware. Gender, age, race, socioeconomic status and insurance status were used as potential variables in identifying disparities. RESULTS: We found no significant disparities between sexes, race or patients who were classified as having socioeconomic status 1-3. There was a lower survival rate associated with having the poorest socioeconomic status and in patients who used Medicare. Uninsured patients had the best survival outcomes and patients with Medicare had the poorest survival outcomes. CONCLUSION: Although we have closed the gap on sex and racial disparities, there remains a difference in survival outcomes across socioeconomic classes and insurance types.
