ABSTRACT Objective To compare maternal and neonatal adverse outcomes between women who are English proficient (EP) and those who have limited English proficiency (LEP). Design Retrospective cohort study. Setting Single US academic medical centre with interpreter services. Population All pregnant women with deliveries during the study period. Methods We retrospectively identified EP and LEP individuals (categorised by self‐report) who delivered at Mayo Clinic, Rochester, Minnesota, USA, from 2015 to 2019. Overall composite adverse outcomes, as well as maternal and neonatal composite outcomes, were measured with generalised linear models and logistic regression, reporting estimates and 95% CIs. Multivariable logistic regression analysis was used to assess associations between language proficiency and outcome measures while controlling for other clinical factors. Main Outcome Measures Composite overall, maternal and neonatal adverse outcomes. Results Among 10 427 EP and 900 LEP participants, the LEP group had a higher incidence of gestational diabetes, unplanned intensive care unit admission, uterine rupture, postpartum haemorrhage with transfusion, neonatal death and 5‐min Apgar score less than 7. The composite overall, maternal and neonatal adverse outcomes were more prevalent in the LEP group than the EP group in unadjusted analysis. Of these, the composite adverse outcome remained significant when the model was adjusted (odds ratio, 1.40; 95% CI, 1.03–1.90). Conclusions Pregnant women with LEP had increased incidence of adverse delivery outcomes, even in a setting with universal availability of medical interpreters.

Objective: Postoperative nausea and vomiting (PONV) is a frequent adverse event after bariatric surgery and is associated with patient dissatisfaction and increased health care burden. Aggressive multimodal antiemetic prophylaxis and the use of propofol infusion during anesthesia are associated with the reduction of PONV. In this study, we examined the use of rescue antiemetics following bariatric surgery performed with 3 different anesthetic strategies designed to reduce PONV: (1) primary volatile (VOL) anesthetic and propofol (PROP) infusion (VOL+PROP), (2) volatile anesthetic with propofol and dexmedetomidine (DEX) infusions (VOL+PROP+DEX), or (3) opioid-sparing total intravenous anesthesia (PROP+DEX). Methods: In this retrospective observational study, we included patients undergoing bariatric surgery from 2018-2022 who received 1 of 3 anesthetics: (1) VOL+PROP, (2) VOL+PROP+DEX, or (3) opioid-sparing PROP+DEX without a VOL. Inverse probability of treatment weighting analysis determined the association between the need for rescue-antiemetics in the postanesthesia care unit (PACU) and following PACU discharge. Results: Three hundred thirty-two patients received VOL+PROP, 354 VOL+PROP+DEX, and 166 PROP+DEX, and all received prophylactic antiemetics during surgery. After surgery, the PROP+DEX patients received fewer rescue antiemetics in the PACU compared with VOL+PROP (11% vs. 24%, P=0.002), and VOL+PROP+DEX fewer compared with VOL+PROP (16% vs. 24%, P=0.023). This differential antinausea effect was limited to PACU stay only. Rescue antiemetic use increased across all anesthetic management groups following PACU discharge until midnight on the day of surgery (ranging from 38% to 46% across groups, P=0.71) and through the first postoperative day (ranging from 47% to 57% across groups, P=0.20). Conclusions: The benefit associated with anesthetic strategies designed to reduce PONV was present but did not persist past PACU discharge. This finding suggests that aggressive perioperative multimodal antiemetic prophylaxis combined with anesthetic strategies designed to prevent PONV after bariatric surgery have only a short-lived effect, thus health care staff in hospital wards may expect to encounter high rates of PONV in these patients. There is a need for the development of novel antinausea treatments to reduce the rate of this frequent postoperative complication.

Background Short-term outcomes after pancreatoduodenectomy (PD) are well-studied, but long-term reoperation rates and their indications remain poorly characterized. Methods A single-center retrospective chart review was performed on patients who underwent PD for pancreatic adenocarcinoma between 1/2011 and 12/2021. Reoperations occurring >90 days after PD were dichotomized to being related or unrelated to the index PD or pancreatic adenocarcinoma. The Kaplan-Meier analysis estimated the incidence of long-term reoperation at 1 and 5 years postoperatively. Results Six-hundred twenty-eight patients were included. The 5-year incidence of any additional operation >90 days after PD was 30.0% (95% CI 23.2-36.2%), and the 5-year incidence of any long-term related reoperation was 21.2% (95% CI 15.0-26.8%). The most common indications for reoperations by 5-year incidence were cancer recurrence (12.8%, 95% CI 7.6-17.7%), incisional hernia (6.2%, 95% CI 2.6-9.7%), small bowel obstruction (1.3%, 95% CI 0.2-2.4%), and leak, fistula, or infection (1.0%, 95% CI 0.1-2.0%). Of the examined risk factors, only 90-day reoperation was found to be predictive of long-term related reoperations ( P = 0.02). Additionally, the 5-year incidence of endoscopic or interventional radiology procedures was 20.2% (95% CI 14.5-25.4%). However, 40.9% (95% CI 33.6-47.3%) of patients required additional surgery or procedures of any kind between 90 days and 5 years after PD. Discussion Within 5 years of PD, one in three patients required additional surgery, and one in five had operations for related indications. Related reoperative indications included recurrence, hernia, PD-specific complications, and small bowel obstruction. However, the rates of each of these reoperations were relatively low.

Abstract Background Postoperative nausea and vomiting (PONV) is frequent after bariatric surgery. We hypothesized that when compared with a volatile-based technique incorporating propofol infusions, the need for rescue antiemetics would be reduced by the use of two strategies: 1) the addition of dexmedetomidine infusions, and 2) the avoidance of opioid and volatile anesthetics, and that this reduction would be observed in the PACU following PACU discharge. Methods In this retrospective observational study we included patients undergoing bariatric surgery from 2018–2022 who received one of three anesthetic strategies: 1) volatile anesthetic and propofol infusion (VOL + PROP), 2) VOL + PROP with the addition of dexmedetomidine (DEX), or 3) opioid-sparing total intravenous anesthesia (PROP + DEX). Inverse probability of treatment weighting analysis determined the association between the need for rescue-antiemetics in the PACU following PACU discharge. Results 332 patients received VOL + PROP, 354 VOL + PROP + DEX, and 166 PROP + DEX. PROP + DEX received fewer rescue antiemetics in PACU compared to VOL + PROP (11% vs 24%, P = 0.002), and VOL + PROP + DEX fewer compared to VOL + PROP (16% vs 24%, P = 0.023). This differential effect was limited to PACU stay; antiemetic use increased across all groups following PACU discharge until midnight (ranging from 38–46% across groups, P = 0.71) and through the first postoperative day (ranging from 47–57%, P = 0.20). Conclusions The benefit associated with two PONV prevention strategies, the addition of dexmedetomidine infusion or avoidance of opioid and volatile anesthetics, did not persist after PACU discharge. These findings highlight the challenge of PONV on postoperative wards, and the need for a novel multimodal team approach to mitigate this complication.

BACKGROUND: Roux-en-Y gastric bypass (RYGB) demonstrates high rates of type 2 diabetes mellitus (T2DM) remission, a phenomenon hypothesized to be mediated mainly by weight loss. Compared with procedures that do not bypass the proximal small intestines, such as sleeve gastrectomy (SG), RYGB exhibits weight loss–independent intestinal mechanisms conducive to T2DM remission. We investigated continued diabetes remission (CDR) rates despite weight recurrence (WR) after RYGB compared with an SG cohort. STUDY DESIGN: A retrospective review of patients who underwent successful primary RYGB or SG with a BMI value of 35 kg/m 2 or more and a preoperative diagnosis of T2DM was performed. Patients with less than 5 years of follow-up, absence of WR, or lack of T2DM remission at nadir weight were excluded. After selecting the optimal procedure for glycemic control, rates of CDR were then stratified into WR quartiles and compared. RESULTS: A total of 224 RYGB and 46 SG patients were analyzed. The overall rate of CDR was significantly higher in the RYGB group (75%) compared with the SG group (34.8%; p < 0.001). The odds of T2DM recurrence were 5.5 times higher after SG compared with RYGB. Rates of CDR were stratified into WR quartiles (85.5%, <25%; 81.7%, 25% to 44.9%; 63.2%, 45% to 74.9%; and 60%, >75%). Baseline insulin use, higher preoperative glycosylated hemoglobin, and longer preoperative duration of T2DM were associated with T2DM recurrence, whereas WR was not. CONCLUSIONS: T2DM remission rates after RYGB are maintained despite WR, arguing for a concurrent weight loss–independent metabolic benefit likely facilitated by bypassing the proximal small intestine.

ImportanceLimited literature exists on surgical outcomes after selective deep lobe parotidectomy (SDLP) with preservation of superficial lobe for patients with benign deep lobe tumors.ObjectiveTo compare the following factors for SDLP vs total parotidectomy for patients with benign tumors in the deep lobe: postoperative complications, including facial nerve paresis or paralysis, Frey syndrome, first bite syndrome, cosmetic defect, sialocele formation, and wound infection; and tumor control and recurrence.Design, Setting, and ParticipantsThis case series included 273 adults who underwent SDLP (n = 177) or total parotidectomy (n = 96) at a single tertiary care institution for benign parotid tumors located in the deep lobe or deep lobe and parapharynx from January 1, 2000, to December 31, 2020.ExposureSelective deep lobe parotidectomy vs total parotidectomy.Main Outcomes and MeasuresIncidence of postoperative complications and tumor recurrence.ResultsAmong 273 patients (SDLP, 177 [65%]; 122 women [69%]; median age at surgery, 58 years [IQR, 46-67 years]; total parotidectomy, 96 [35%]; 57 women [59%]; median age at surgery, 59 years [IQR, 40-68 years]), the most common tumor was pleomorphic adenoma (SDLP, 128 of 177 [72%]; total parotidectomy, 62 of 96 [65%]). An abdominal dermal fat graft was less commonly performed for patients who underwent SDLP than those who underwent total parotidectomy (2 of 177 [1%] vs 20 of 96 [21%]; difference, −20% [95% CI, −28% to −11%]). The rate of great auricular nerve preservation was higher in the SDLP group than in the total parotidectomy group (84 of 102 [82%] vs 20 of 34 [59%]; difference, 24% [95% CI, 5%-42%]). No meaningful difference in length of hospital stay was found. The percentage of patients with House-Brackmann grade I immediately after surgery was 48% (85 of 177) in the SDLP group and 21% (20 of 96) in the total parotidectomy group (difference, 28% [95% CI, 16%-40%]). There were no clinically meaningful differences in rates of hematoma, sialocele, seroma, ear numbness, wound infection, or unplanned return to emergency department or operating room. The SDLP group reported a lower rate of Frey syndrome than the total parotidectomy group (1 of 137 [1%] vs 12 of 78 [15%]; difference, −15% [95% CI, −23% to −7%]), as well as a lower rate of facial contour defect (28 of 162 [17%] vs 25 of 84 [30%]; difference, −13% [95% CI, −24% to −1%]) and a higher rate of first bite syndrome (34 of 148 [23%] vs 7 of 78 [9%]; difference, 14% [95% CI, 5%-23%]). The percentage of patients with House-Brackmann grade I at their first follow-up visit was 67% (118 of 177) in the SDLP group compared with 49% (47 of 96) in the total parotidectomy group (difference, 17% [95% CI, 4%-30%]). There was no clinically meaningful difference in House-Brackmann grade after 1 year.Conclusions and RelevanceFindings of this case series study suggest that SDLP can be considered an effective and even superior technique for management of benign tumors in the deep parotid lobe. Advantages associated with SDLP include reduction in need for reconstruction for facial contour defect and reduction in complications, such as immediate facial nerve weakness and Frey syndrome. The incidence of first bite syndrome was higher in the SDLP group. Tumor control was not compromised by SLDP.

ObjectiveFailure to recognize symptoms of non‐human papillomavirus‐associated oropharyngeal squamous cell carcinoma (HPV(−)OPSCC) at presentation can delay diagnosis and treatment. We aim to identify patient factors and provider practice patterns that delay presentation and care in HPV(−)OPSCC.MethodsRetrospective review at a tertiary care center. Patients with HPV(−)OPSCC receiving treatment from 2006 to 2016. Patients were excluded if their date of symptom onset or diagnosis was unknown after thorough review of the electronic medical record or their tissue was not tested for HPV or p16. Clinical data, workup, and care timelines were abstracted. Univariate and multivariable linear regressions were performed to determine associations between patient and provider factors and delays in care.ResultsOf 70 included patients, 52 (74%) were male and mean age was 60.5 (SD = 9.0). Median time to diagnosis was 69 days (IQR = 32–127 days), with a median latency of 30 days (IQR = 12–61 days) from symptom onset to first presentation and 19.5 days (IQR = 4–46 days) from the first presentation to diagnosis. Most patients visited at least 2 providers (n = 52, 74%) before diagnosis. Evaluation by 3 or more providers prior to diagnosis was associated with significant delays in diagnosis of nearly a year (357.7 days, p < 0.001) and being treated or prescribed analgesia prior to diagnosis was significantly associated with delays in diagnosis (p = 0.004) on univariate regression analysis.ConclusionsDelays in care related to evaluations by multiple providers and misdiagnosis prolonged time to diagnosis in HPV(−)OPSCC. Improved patient and provider education is necessary to expedite the diagnosis of HPV(−)OPSCC.Level of Evidence4 Laryngoscope, 133:1394–1401, 2023
