Published: January 2021

Introduction After extensive mediastinal dissection fails to achieve adequate intra-abdominal esophageal length, a Collis gastroplasty(CG) is recommended to decrease axial tension and reduce hiatal hernia recurrence. However, concerns exist about staple line leak, and long-term symptoms of heartburn and dysphagia due to the acid-producing neoesophagus which lacks peristaltic activity. This study aimed to assess long-term satisfaction and GERD-related quality of life after robotic fundoplication with CG (wedge fundectomy technique) and to compare outcomes to patients who underwent fundoplication without CG. Outcomes studied included patient satisfaction, resumption of proton pump inhibitors (PPI), length of surgery (LOS), hospital stay, and reintervention. Methods This was a single-center retrospective analysis of patients from January 2017 through December 2018 undergoing elective robotic hiatal hernia repair and fundoplication. 61 patients were contacted for follow-up, of which 20 responded. Of those 20 patients, 7 had a CG performed during surgery while 13 did not. There was no significant difference in size and type of hiatal hernias in the 2 groups. These patients agreed to give their feedback via a GERD health-related quality of life (GERD HRQL) questionnaire. Their medical records were reviewed for LOS, length of hospital stay (LOH), and reintervention needed. Statistical analysis was performed using SPSS v 25. Satisfaction and need for PPIs were compared between the treatment and control groups using the chi-square test of independence. Results Statistical analysis showed that satisfaction with outcome and PPI resumption was not significantly different between both groups ( P > .05). There was a significant difference in the average ranks between the 2 groups for the question on postoperative dysphagia on the follow-up GERD HRQL questionnaire, with the group with CG reporting no dysphagia. There were no significant differences in the average ranks between the 2 groups for the remaining 15 questions ( P > .05). The median LOS was longer in patients who had a CG compared to patients who did not (250 vs. 148 min) ( P = .01). The LOH stay was not significantly different ( P > .05) with a median length of stay of 2 days observed in both groups. There were no leaks in the Collis group and no reoperations, conversions, or blood transfusions needed in either group. Conclusion Collis gastroplasty is a safe option to utilize for short esophagus noted despite extensive mediastinal mobilization and does not adversely affect the LOH stay, need for reoperation, or patient long-term satisfaction.

Published: January 2021

Background Recurrent laryngeal nerve (RLN) injury and postoperative hypocalcemia are potential complications of thyroidectomy, particularly in malignancy. Intraoperative nerve monitoring (IONM) remains controversial. We sought to evaluate the impact of IONM on these complications using a national data set. Methods The American College of Surgeons National Surgical Quality Improvement Program thyroidectomy-targeted data set was queried for patients who underwent thyroidectomies from 2016 to 2017. Patients were grouped according to IONM use. Logistic regression models were constructed to evaluate associations of variables with 30-day hypocalcemic events (HCEs) and RLN injury. Associations were expressed as odds ratios (ORs) with 95% confidence intervals (95% CIs). A subgroup analysis was performed of patients with malignancy. Results A total of 9527 patients were identified; 5969 (62.7%) underwent thyroidectomy with IONM and 3558 (37.3%) without. By multivariable analysis, IONM had protective associations with HCE (OR = .81, 95% CI = .68-.96; P = .013) and RLN injury (OR = .83, 95% CI = .69-.98; P = .033). Malignancy increased risk of HCE (OR = 1.21, 95% CI=1.01-1.45; P = .038) and RLN injury (OR = 1.22, 95% CI = 1.02-1.46; P = .034). A large proportion (5943/9527, 62.4%) of patients had malignancy; 3646 (61.3%) underwent thyroidectomy with IONM and 2297 (38.7%) without. In the subgroup analysis, IONM had stronger protective associations with HCE (OR = .73, 95% CI = .60-.90; P = .003) and RLN injury (OR = .76, 95% CI = .62-.94; P = .012). Discussion Malignancy was associated with increased risk of HCE and RLN injury. Intraoperative nerve monitoring had a protective association with HCE and RLN injury, both overall, and in the malignant subgroup. Intraoperative nerve monitoring was correlated with improved thyroidectomy outcomes, especially if the indication was malignancy. This warrants further study to clarify cause and effect.

Published: January 2021

Background Although pilonidal sinus disease is common, development of associated malignancy is very rare. After surgical treatment, most surgeons send the excision material for a histopathological examination. The aim of this study was to examine whether it is necessary to routinely send the pilonidal sinus surgical excision material for this examination. Method The data of 3146 patients were retrospectively screened, and 2486 patients with available histopathological reports of the excision material were included in the study. Results Of the 2486 patients included in the study, 2165 were men and 321 were women, and 94.7% of the patients were under the age of 50 years while 5.3% were 50 years or above. The rate of patients who underwent surgery due to recurrence was 1.2%. No malignancy was detected in any patient after the histopathological examination. Discussion In this study, none of the pathology results was reported as malignant. This confirms that it is necessary to ask the question whether we should routinely send the surgical excision material for a histopathological examination.

Published: January 2021

Introduction Congestive heart failure (CHF) is a known risk factor for increased postoperative morbidity. However, the safety in patients with CHF has not been well established. The objective of this study was to assess the safety of surgery in patients with a history of CHF undergoing bariatric surgical procedures. Methods Retrospective review of a prospectively maintained Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) Center of Excellence database. Patients with known CHF undergoing bariatric procedures over an 11-year period were reviewed. Results Over the 11-year period, 4470 total bariatric surgeries were performed, of which 41 (.92%) patients had known CHF. Twenty-one patients were men (51.2%) with a mean age of 55.8 years and mean body mass index (BMI) of 51.9. Comorbidities included hypertension (87.8%), obstructive sleep apnea (80.5%), osteoarthritis (63.4%), gastroesophageal reflux disease (56%), and diabetes (53.7%). Surgical procedures included 16 sleeve gastrectomies (SGs) (39%), 11 Roux-en-Y gastric bypasses (RYGBs) (26.8%), 10 laparoscopic adjustable gastric bands (LAGBs) (24.4%), 1 removal of a gastric band and conversion to SG (2.4%), 1 removal of a gastric band to RYGB (2.4%), 1 gastric band over RYGB pouch (2.4%), and 1 gastric band replacement (2.4%). All cases were performed minimally invasively (73.2% laparoscopic and 26.8% robotic). Mean LOS was 2.53 days. Thirty-day complications included 2 readmissions (4.9% [1 small bowel obstruction and 1 pulmonary edema]), 1 reoperation (2.4% [small bowel obstruction]), and 1 mortality (2.4%) on postoperative day 30 unrelated to the surgery. Conclusions Bariatric surgery can be performed safely in patients with CHF.

Published: January 2021

Background Sternal and rib fractures are common concomitant injuries. However, the impact of concurrent sternal fractures on clinical outcomes of patients with rib fractures is unclear. We aimed to unveil the pulmonary morbidity and mortality impact of concomitant sternal fractures among patients with rib fractures. Methods We identified adult patients admitted with traumatic rib fractures with vs. without concomitant sternal fractures using the 2012-2014 National Inpatient Sample (NIS). After 2:1 propensity score matching and adjustment for residual imbalances, we compared risk of pulmonary morbidity and mortality between patients with vs. without concomitant sternal fractures. Subgroup analysis in patients with flail chest assessed whether sternal fractures modify the association between undergoing surgical stabilization of rib fractures (SSRF) and pulmonary morbidity or mortality. Results Of 475 710 encounters of adults admitted with rib fractures, 24 594 (5%) had concomitant sternal fractures. After 2:1 propensity score matching, patients with concomitant sternal fractures had 70% higher risk (95% CI: 50-90% higher, P < 0.001) of undergoing tracheostomy, 40% higher risk (30-50% higher, P <.001) of undergoing intubation, and 20% higher risk of respiratory failure (10-30% higher, P <.001) and mortality (10-40% higher, P =.007). Subgroup analysis of 8600 patients with flail chest showed concomitant sternal fractures did not impact the association between undergoing SSRF and any pulmonary morbidity or mortality. Conclusion Concomitant sternal fractures are associated with increased risk for pulmonary morbidity and mortality among patients with rib fractures. However, our findings are limited by a binary definition of sternal fractures, which encompasses heterogeneous injury patterns with likely variable clinical relevance.
Nighttime Calls, Pages, and Interruptions to the On-Call Surgery Resident
Authors: Parrado Raphael H. , Notrica David M , Molitor Mark S. 
Published: January 2021

Background Communication is a keystone to good medical practice. At night, as physician numbers decrease, frequent, nonurgent interruptions have shown to disrupt patient care and impact resident/physician wellness. Potentially, interruptions can lead to an increase in medical errors. The frequency and activities interrupted during night calls have not been fully described. Methods For a period of 44 days (August through September), all calls and pages received during the 12-hour night call session were documented. Calls were analyzed by caller, urgency, need for intervention, and resident interrupted by the communication. Results A total of 494 communications were identified with a mean of 10 calls per shift (IQR 7-14). Communications lasted a mean of 2.7 +/− 2.9 minutes. Direct calls occurred in 78% and pages in 22% of the cases. From the non-ED calls (n = 335), most of them came from nursing staff (85%), followed by other specialties (12%). Five percent of the calls were directed to the wrong service. Communications occurred during charting (41%), patient assessment (33%), interrupted resident’s sleep (12%), or during a surgical procedure (6%). Communication required no action in 47% of the cases. A physician order was needed in 41%, while bedside clinical assessment was required in 12% of the calls. Conclusions Communications are common at night, but most did not require clinical assessment. A large portion of communications interrupted direct patient care. An opportunity exists to eliminate nonproductive communications and improve the quality of medical education.

Published: January 2021

Background In Jan 2018, we began routinely obtaining neck ultrasound (US) with 123I/99Tc-sestamibi (MIBI) for parathyroid gland localization and to identify thyroid pathology in the setting of primary hyperparathyroidism (1HPT). The aim of this study is to assess if routine neck US is a useful adjunct to 123I/99Tc-MIBI in 1HPT. Methods Patients undergoing surgery for 1HPT with both 123I/99Tc-MIBI and US at our institution after implementation of routine US were reviewed. Biopsy and surgical management of thyroid pathology was evaluated. 123I/99Tc-MIBI and US results were compared to intraoperative findings to determine sensitivity and positive predictive value (PPV) for parathyroid localization. Results From January 2018 to September 2019, there were 423 patients (mean, 61 years) that met inclusion criteria (80% women). Thyroid nodules were found on US in 57%, mean size 1.3 + 0.8 cm. Fine needle aspiration (FNA) was performed in 87 patients with nodules (36%). 35 patients (8.5%) required total or partial thyroidectomy for diagnoses/treatment. Papillary thyroid cancer (PTC) was found in 3.5% of the cohort with micro-PTC 53% and PTC 1-2 cm 40%. A successful parathyroid operation for 1HPT was achieved in 98.6% of patients. Positive predictive value for localization of abnormal parathyroid glands was 97% when US and 123I/99Tc-MIBI had concordant findings. Discussion Routine use of US in 1HPT commonly identifies nodules that are benign or low-risk PTC. Ultrasound is less sensitive for parathyroid localization but when used with 123I/99Tc-MIBI, concordant imaging has a high PPV.
Giant haemorrhagic hepatic cyst with flame-like morphology in a patient with polycystic kidney and liver disease
Authors: Brusic Ana , Oo June , Stella Damien L , Simkin Paul M , Loveday Benjamin PT 
Published: January 2021

Introduction Intracystic haemorrhage is a rare complication of hepatic cysts, and is often mistaken for a malignant lesion. Case Report A 55-year-old female with a history of polycystic kidney and liver disease presented with a six-month history of abdominal distension, abdominal pain, early satiety, shortness of breath and 5 kg of weight loss. Imaging revealed a 20 cm mixed solid-cystic hepatic lesion containing peripheral avascular mobile echogenic material with a flame-like morphology. After experiencing symptomatic relief from ultrasound-guided aspiration, the patient underwent cyst fenestration for more definitive treatment. Discussion Haemorrhagic hepatic cysts are uncommon and may present on imaging as having lace-like retractile clot, internal layering or shading of separating blood products or avascular mobile flame-like excrescences. The presence of avascular mobile flame-like excrescences appears to be a unique feature of haemorrhagic hepatic cysts. Conclusion While haemorrhagic hepatic cysts are rare and commonly mistaken for biliary cystadenomas or adenocarcinomas, the identification of particular features on high-resolution magnetic resonance imaging and contrast-enhanced ultrasound can lead to the correct diagnosis.

AbstractBackgroundFluid overload is related to the development and prognosis of cardiac surgery-associated acute kidney injury (CSA-AKI). The study is to investigate the influence of serum creatinine (SCr) corrected by fluid balance on the prognosis of patients with cardiac surgery.MethodsA retrospective study was conducted in 1334 patients who underwent elective cardiac surgery from January 1 to December 31, 2015. Kidney Disease: Improving Global Outcomes (KDIGO) criteria for AKI were applied to identify CSA-AKI. SCr was measured every 24 h during ICU period and was accordingly adjusted for cumulative fluid balance. Changes in SCr, defined as ∆Crea, were determined by difference between before and after adjustment for cumulative fluid balance. All patients were then divided into three groups: underestimation group (∆Crea ≥ P75), normal group (P25 < ∆Crea < P75) and overestimation group (∆Crea ≤ P25).ResultsThe incidence of AKI increased from 29.5% to 31.8% after adjustment for fluid balance. Patients in underestimation group showed prolonged length of ICU stay compared with normal group and overestimation group (3.2 [1.0–4.0] vs 2.1 [1.0–3.0] d,P < 0.001; 3.2 [1.0–4.0] vs 2.3 [1.0–3.0] d,P < 0.001). Length of hospital stay and mechanical ventilation dependent days in underestimation group were significantly longer than normal group (P < 0.001). Multivariate analysis showed age, baseline SCr and left ventricular ejection fraction were independently associated with underestimation of creatinine.ConclusionsCumulative fluid balance after cardiac surgery disturbs accurate measurement of serum creatinine. Patients with underestimation of SCr were associated with poor prognosis.

AbstractBackgroundOlder people are often admitted for rehabilitation to improve walking, yet not everyone improves. The aim of this study was to determine key factors associated with a positive response to hospital-based rehabilitation in older people.MethodsThis was a secondary data analysis from a multisite randomized controlled trial. Older people (n= 198, median age 80.9 years, IQR 76.6- 87.2) who were admitted to geriatric rehabilitation wards with a goal to improve walking were recruited. Participants were randomized to receive additional daily physical therapy focused on mobility (n = 99), or additional social activities (n = 99). Self-selected gait speed was measured on admission and discharge. Four participants withdrew. People who changed gait speed ≥0.1 m/s were classified as ‘responders’ (n = 130); those that changed <0.1m/s were classified as ‘non-responders’ (n = 64). Multivariable logistic regression explored the association of six pre-selected participant factors (age, baseline ambulation status, frailty, co-morbidities, cognition, depression) and two therapy factors (daily supervised upright activity time, rehabilitation days) and response.ResultsResponding to rehabilitation was associated with the number of days in rehabilitation (OR 1.04; 95% CI 1.00 to 1.08; p = .039) and higher Mini Mental State Examination scores (OR 1.07, 95% CI 1.00 – 1.14; p = .048). No other factors were found to have association with responding to rehabilitation.ConclusionIn older people with complex health problems or multi-morbidities, better cognition and a longer stay in rehabilitation were associated with a positive improvement in walking speed. Further research to explore who best responds to hospital-based rehabilitation and what interventions improve rehabilitation outcomes is warranted.Trial registrationAustralian New Zealand Clinical Trials Registry ACTRN12613000884707; ClinicalTrials.gov IdentifierNCT01910740.
Life after falls prevention exercise – experiences of older people taking part in a clinical trial: a phenomenological study
Authors: Finnegan Susanne , Bruce Julie , Seers Kate 
Published: January 2021

Abstract
Background
There is little evidence about the lived experience of older people who have completed a falls prevention exercise programme and their life beyond their intervention.

Method
A phenomenological interview study with 23 participants (12 females), mean age 81 years (range 74–93 years), residing in their own homes across England, who had participated in a falls prevention exercise intervention within the Prevention of Falls Injury Trial (PreFIT). The aims were to explore their experiences of:

being in a clinical trial involving exercise.

exercise once their falls prevention intervention had finished.

Interpretative data analysis was informed by van Manen’s (1997) framework for phenomenological data.

Results
Analysis of interviews about experiences of participating in PreFIT and what happened once the falls intervention ended identified five themes: Happy to help; Exercise behaviours; “It keeps me going”; “It wasn’t a real fall”; and Loss. Participants did not continue their specific exercises after they had completed the intervention. They preferred walking as their main exercise, and none reported preventing falls as a motivator to continue exercising. Participant experiences suggest that they have their own ideas about what constitutes a fall and there is disparity between their interpretation and the definition used by healthcare professionals and researchers.

Conclusion
Despite good intentions and perceived benefits, on-going participation in falls prevention exercises beyond a structured, supervised intervention was not a priority for these older people. Promoting continuation of falls prevention exercises post-intervention is just as challenging as promoting uptake to and adherence during exercise programmes.
Post-transplant manifestation of ankylosing spondylitis: a case report and review of literature
Authors: Zawiasa-Bryszewska Anna , Brzezińska Olga , Kurnatowska Ilona , Makowska Joanna 
Published: January 2021

Abstract
Background
Ankylosing spondylitis (AS) is an insidiously progressive and debilitating form of arthritis involving the axial skeleton, characterized by chronic back pain and progressive spinal stiffness, and lessening of pain and stiffness with exercise. Due to subsequent manifestation in different organs, AS causes reduction in life expectancy, so early diagnosis and treatment are of great importance. No AS cases have been reported in solid-organ transplant recipients yet.

Case presentation
A 58-year-old woman with end-stage renal disease due to chronic glomerulonephritis, after allogenic kidney transplantation 25 years earlier, with stable, good graft function, treated with chronic immunosuppressive therapy based on cyclosporine A, mycophenolate mofetil, and prednisone, with no previous history of a connective tissue disease presented fever up to 39 °C accompanied by pain localized in sacroiliac region radiating to the left lower limb. Detailed diagnostic procedures and x-rays of the lumbar spine and of the targeted sacroiliac joints revealed lesions characteristic of AS. Sulphasalazine was added to standard immunosuppression regimen with good clinical results.

Conclusions
We report an adult kidney transplant recipient with a new onset of AS. The risk of relapse or new onset of inflammatory disease in transplant recipients is extremely low due to immunosuppressive therapy following transplantation. However, when it occurs, the clinical presentation is commonly atypical, often leading to delayed diagnosis.
