Online informational bariatric seminars: increasing access to bariatric surgery or widening a divide?

BACKGROUND: Historically our institution has required prospective bariatric patients attend an in-person introductory seminar prior to their first clinic visit. Utilization of the internet has increased dramatically over the last 10 years and in 2016, we added an online seminar. With the emergence of COVID-19 and new rules regarding social distancing, we are currently relying exclusively on web-based orientation. Research suggests there are racial and socioeconomic disparities in the utilization of internet health resources in the general population. To our knowledge this has not been studied in regard to the bariatric population. METHODS: A retrospective chart review was performed on patients who attended online (OS) and in-person seminars (IPS). Our primary endpoint was to compare the percentage of patients who underwent surgery. Secondary outcomes included differences in demographic and clinical characteristics between the patients who attended the OS versus the IPS. RESULTS: Of the 1152 patients who attended a bariatric orientation, 71.2% scheduled an office visit. The IPS patients had a higher rate of office visits and shorter time between orientation and first visit. Of patients eligible for surgery, there was a higher percentage of Caucasians in the OS group while the IPS group had higher rates of Hispanic and African Americans. Patients from the OS group had higher rates of marriage and employment, and lower rates of medical co-morbidities. When controlling for age, sex, race/ethnicity, marital status, employment status and medical co-morbidities, there was no significant impact of type of orientation on progression to surgery. CONCLUSION: We found that there was no difference in progression to surgery between the two orientation groups. Importantly, however, we detected marked demographic and clinical differences between the two patient populations. There is an urgent need to address these disparities as we are now heavily relying on patient outreach and education via the internet.

Wandering spleen in a geriatric patient - a rare presentation of gastric volvulus.

We report atypical gastric outlet obstruction in a geriatric patient caused by acute mesenteroaxial gastric volvulus precipitated by a wandering spleen.

Efficacy of pre-operative nasal staphylococcus aureus screening and chlorhexidine chest scrub in decreasing the incidence of post-resection empyema.

BACKGROUND: We evaluated the efficacy of pre-operative Staphylococcus aureus (SA) screening and chlorhexidine chest scrub in decreasing the incidence of empyema after major pulmonary resections. METHODS: For two years, a strategy aimed at decreasing post-resection empyema was instituted. This entailed pre-operative screening for nasal SA and chlorhexidine chest scrub the night before surgery (Group Swab-Scrub, n=192). Patients screened positive for SA, methicillin-resistant (MRSA) and methicillin-sensitive (MSSA), received 5 d of nasal mupirocin. Group Swab-Scrub was compared with patients two years earlier, who did not receive this pre-operative maneuver (Group Control, n=173). The extent of resection considered was lobectomy or greater. All patients received cefazolin (or clindamycin if allergic) prior to incision and 24 h postoperatively, except for patient in Group Swab-Scrub screening positive for MRSA, who received vancomycin. All patients had povidone-iodine skin preparation. RESULTS: In Group Swab-Scrub, prevalence of nasal SA was 8.9% (17/192) two with MRSA and 15 with MSSA. There was no difference in patient demographics or operative characteristics between the Group Swab-Scrub and Group Control. There was also no difference in prolonged air-leak, empyema, wound infection, pneumonia, or mortality rates between the two groups. When stratifying for the extent of procedure, there was no difference in the incidence of empyema after lobectomy (Group Swab-Scrub, 3.9% [7/177] versus Group Control, 2.0% [3/151]; p=0.352) or pneumonectomy (Group Swab-Scrub, 6.7% [1/15] versus Group Control, 13.6% [3/22]; p=0.633). In both univariate and multivariable analysis, prolonged air-leak and pneumonectomy were significant risk factors for empyema. CONCLUSIONS: Preoperative screening for nasal SA and chlorhexidine chest scrub does not seem to decrease empyema rates after major pulmonary resection. Prolonged air-leak and pneumonectomy continue to be significant risk factors for developing empyema. The number of patients undergoing pneumonectomy in this study is small and further studies are needed for this patient population.

A randomized comparison of different ventilator strategies during thoracotomy for pulmonary resection.

OBJECTIVE: Protective lung ventilation is reported to benefit patients with acute respiratory distress syndrome. It is not known whether protective lung ventilation is also beneficial to patients undergoing single-lung ventilation for elective pulmonary resection. METHODS: In an institutional review board-approved prospective randomized trial, 34 patients undergoing elective pulmonary resection requiring single-lung ventilation were enrolled. Informed consent was obtained. Patients were randomized to 1 of 2 groups: (1) high tidal volume (Hi-TV) of 10 mL/kg, rate of 7 breaths/min, and zero positive end-expiratory pressure or (2) low tidal volume (Lo-TV) of 5 mL/kg, rate of 14 breaths/min, and 5 cmH2O positive end-expiratory pressure. Ventilator settings were continued during both double- and single-lung ventilation. Pulmonary functions, hemodynamics, and postoperative outcomes were recorded. RESULTS: Patient demographics, operative characteristics, intraoperative hemodynamics, and postoperative pain and sedation scores were similar between the 2 groups. During most time periods, airway pressures (peak and plateau) were significantly higher in the Hi-TV group; however, plateau pressures remained less than 30 cmH2O at all times for all patients. The Hi-TV group had significantly lower arterial carbon dioxide tension, less arterial carbon dioxide tension-end-tidal carbon dioxide gradient, lower alveolar dead space ratio, and higher dynamic pulmonary compliance. There were no differences in postoperative morbidity and hospital days between the 2 groups, but atelectasis scores on postoperative days 1 and 2 were lower in the Hi-TV group. CONCLUSIONS: The use of Hi-TV during single-lung ventilation for pulmonary resection resulted in no increase in morbidity and was associated with less hypercarbia, less dead space ventilation, better dynamic compliance, and less postoperative atelectasis.
