The Comparison of Long-term Surgical Results for Sensory Exotropia and Comitant Exotropia

Purpose: To compare the long-term surgical outcomes of patients with sensory and concomitant exotropia and to define the factors associated with successful surgical outcomes in those with sensory exotropia.Methods: The medical records of patients with sensory exotropia who underwent operations and were followed-up for at least 2 years were retrospectively reviewed. We enrolled patients exhibiting only best-corrected visual acuities ≤ 20/100 of the operated eyes. Surgical success was defined as a final distance deviation < 10 prism diopters (PD) with the eye in the primary position. Twenty-eight patients operated upon to treat sensory exotropia and 28 who underwent operations to treat concomitant exotropia who did not differ in terms of the gaze deviation angle were matched in terms of age, sex, and the preoperative distance and near distributions; their surgical outcomes were compared. Factors affecting such outcomes were identified using a multivariate Cox’s proportional hazards model.Results: The mean follow-up times were 91.7 ± 45.8 months in the sensory and 42.6 ± 27.7 months in the concomitant exotropia groups. The cumulative probabilities of surgical success 2 years after surgery were 74.5% in the sensory and 74.4% in the intermittent exotropia groups, thus not significantly different (<i>p</i> = 0.988). The Cox’s proportional hazard model showed that a greater difference between the preoperative distant and near deviations was associated with recurrence (<i>p</i> = 0.091).Conclusions: The long-term surgical outcomes of patients with sensory and concomitant exotropia were comparable. A high-level near-distance disparity increased the risk of recurrence.

Long-term outcomes of functional single ventricles associated with heterotaxy syndrome†.

The goal of this study was to determine the long-term surgical outcomes of patients with functional single ventricles associated with heterotaxy syndrome, risk factors for mortality and factors associated with Fontan stage completion. Overall, 279 patients with a functional single ventricle associated with heterotaxy syndrome who underwent an initial surgical procedure at our institute between 1978 and 2021 were grouped into 4 "eras" based on the surgical year during which the initial procedure was performed: era 1 (1978-1989, n = 71), era 2 (1990-1999, n = 98), era 3 (2000-2009, n = 64) and era 4 (2010-2021, n = 46). Neonatal surgery was more frequent in eras 3 and 4 than in eras 1 and 2. Overall, 228 patients had right atrial isomerism; 120 patients (43.0%) had a total anomalous pulmonary venous connection; and 58 patients (20.8%) underwent an initial procedure as neonates. Overall survival rates at 10, 20 and 30 years after the initial procedure were 47.1%, 40.6% and 36.1%, respectively. Neonatal surgery (P < 0.001), total anomalous pulmonary venous connection repair at the initial procedure (P < 0.001) and early era (P < 0.001) were identified as risk factors for mortality, with the last 2 variables being negatively associated with Fontan stage completion (P < 0.001 for both). Although era had a favourable effect on survival, total anomalous pulmonary venous connection with intrinsic pulmonary vein obstruction was associated with both mortality and Fontan stage completion.

Time-of-day discrepancy for the long term surgical outcome of patients with aortic dissection.

It has been suggested that the time of day when cardiovascular surgery is performed may affect the surgery outcomes. This study investigated whether there was a difference in risk-adjusted mortality and morbidity outcomes between patients undergoing acute aortic dissection during the day or the night. Consecutive patients who had undergone Stanford A acute aortic dissection surgery were enrolled between 2016 and 2020. In the daytime group, surgery was performed between 08:00 and 20:00, and in the nighttime group between 20:00 and 8:00. The primary outcome was in-hospital overall mortality, and the secondary outcomes were overall mortality within a median follow-up time of 35.2 (17.0,53.5) months and the occurrence of re-entry tears and major bleeding. A total of 925 patients were enrolled. The primary outcome of in-hospital overall mortality did not differ significantly between patients who received daytime or nighttime surgery. Similarly, the secondary outcomes of overall mortality during the follow-up and incidence of re-entry tears and major bleeding did not differ significantly between the groups. Subgroup analysis was also performed according to the surgery type (modified triple-branched stent-graft implantation or frozen elephant trunk implantation), and surgical approach (partial upper sternotomy or full median sternotomy) confirming that the time of surgery did not significantly influence the outcomes. Cox regression analysis showed that time from onset to admission (P = 0.036), and time from the onset to surgery (P = 0.045) were significant risk factors for increased mortality during follow-up. The time of day when thoracotomy was performed did not significantly affect the clinical outcome and is therefore not a consideration for the improvement of outcome in Stanford A acute aortic dissection patients.

Long-Term Surgical Outcomes of Patients With Isomeric Right and Left Atrial Appendages.

Objectives: To compare the long-term outcomes of biventricular, univentricular, and so-called one-and-one-half ventricular repairs in patients with left and right isomerism. Methods: Surgical correction was undertaken, between 2000 and 2021, in 198 patients with right, and 233 with left isomerism. Results: The median age at operation was 24 days (interquartile range [IQR]: 18-45) and 60 days (IQR: 29-360) for those with right and left isomerism, respectively. Multidetector computed-tomographic angiocardiography demonstrated more than half of those with right isomerism had superior caval venous abnormalities, and one-third had a functionally univentricular heart. Almost four-fifths of those with left isomerism had an interrupted inferior caval vein, and one-third had complete atrioventricular septal defect. Biventricular repair was achieved in two-thirds of those with left isomerism, but under one-quarter with right isomerism (P < .001). Hazard regression for mortality revealed odds for prematurity at 5.5, pulmonary atresia at 2.81, atrioventricular septal defect with a common valvar orifice at 2.28, parachute mitral valve at 3.73, interrupted inferior caval vein at 0.53, and functionally univentricular heart with a totally anomalous pulmonary venous connection at 3.77. At a median follow-up of 124 months, the probability of survival was 87% for those with left, and 77% for those with right isomerism (P = .006). Conclusions: Multimodality imaging characterizes and delineates the relevant anatomical details, facilitating surgical management of individuals with isomeric atrial appendages. Continuing higher mortality despite surgical intervention in those with right isomerism points to the need for the reassessment of strategies for management.

Long-term outcomes and risk factors for mortality of patients with hypertrophic obstructive cardiomyopathy undergoing septal myectomy.

We aimed to evaluate the long-term surgical outcomes of patients with hypertrophic obstructive cardiomyopathy and explore the risk factors for mortality, especially those related to atrial fibrillation. We retrospectively reviewed 150 consecutive patients with hypertrophic obstructive cardiomyopathy who underwent surgical treatment between March 2003 and December 2020. Fifty (33.3%, age 53.7±16.1 years) patients underwent isolated septal myectomy (SM), 79 (52.7%, age 52.3±12.6 years) underwent SM with mitral valve intervention (SM + MVI), and 21 (14.0%, age 57.1±13.5 years) underwent SM with mitral valve replacement (SM + MVR). Overall peak left ventricular outflow tract pressure gradient at rest was significantly decreased from 91.9±43.2 to 13.3±13.0 mmHg (P<0.0001). Survival rates were 96.7%, 89.1%, and 81.5% at 30 days, 5 years, and 10 years, respectively. Patients in the SM + MVI group survived longer than those in SM + MVR or isolated SM groups (94.1% vs. 75.4% vs. 88.0%, respectively, at 5 years, P=0.05). Patients with preoperative atrial fibrillation had a worse 5-year survival rate than those without atrial fibrillation (73.4% vs. 92.8%, respectively, P<0.001). Preoperative atrial fibrillation was an independent risk factor for late mortality in multivariable analysis. Notably, those whose atrial fibrillation was successfully eradicated by surgical ablation had a better 5-year survival rate than other patients (87.7% vs. 28.6%, respectively, P<0.001). Surgical outcomes in hypertrophic obstructive cardiomyopathy are favorable in the long-term, except in patients with preoperative atrial fibrillation. Therefore, intraoperative ablation for preoperative atrial fibrillation in hypertrophic obstructive cardiomyopathy should be actively considered to improve patient outcomes.

No association of postoperative opioid usage with long-term surgery outcomes in patients with liver cancer: a population-based retrospective cohort study.

Hepatocellular carcinoma (HCC) is a fatal cancer worldwide, and surgical resection remains the standard treatment. Postoperative opioid prescription has been believed to affect cancer recurrence through complex biological pathways. We conducted a retrospective cohort study using the Longitudinal Health Insurance Database of Taiwan to evaluate the relationship between postoperative opioid use and long-term surgical outcomes of patients with HCC. This study had a retrospective cohort design. In total, 812 patients older than 20 years who underwent hepatectomy because of HCC were included. The exposure group comprised patients who used opioids during hospitalization postoperatively. The comparison group included those who never used opioids during hospitalization postoperatively. A Cox proportional hazards model was used to evaluate the overall survival or recurrence-free survival rate between the opioid group and the nonopioid group. A total of 530 patients received opioids postoperatively and 282 patients did not. The hazard ratios of overall survival and recurrence-free survival were 1.10 (95% confidence interval [CI], 0.85-1.41) and 1.15 (95% CI, 0.91-1.46), respectively. Total postoperative opioids were converted into oral morphine milligram equivalents and then divided into 3 equal subgroups: low dose, <40 mg; medium dose, 40 to 144 mg; and high dose, ≥145 mg. The hazard ratios of overall survival were 0.88 (95% CI, 0.63-1.24) for the low-dose group, 1.27 (95% CI, 0.92-1.74) for the medium-dose group, and 1.14 (95% CI, 0.83-1.58) for the high-dose group. Postoperative opioids do not affect overall and recurrence-free survival in patients undergoing hepatectomy or liver transplantation because of HCC. Cancer recurrence should not be a clinical concern regarding postoperative opioid prescription.

Long-term Surgical Outcomes in Patients of Centurion Syndrome: A Mystic Etiology of Epiphora in Young

ABSTRACT Aim To describe the clinical features and long-term outcomes of the medial canthal tendon (MCT) release procedure in patients with Centurion Syndrome (CS). Methods We performed a retrospective analysis of the diagnosed patients with CS from July 2013 to December 2019. CS was diagnosed clinically based on the anterior displacement of MCT, anterior dislocation of lacrimal punctum out of tear lake, prominent nasal bridge, beak sign, and synophyrs. All symptomatic patients were advised the anterior limb of MCT release with modified closure of the skin incision. The outcome measures were based on Munk’s score (subjective) and the fluorescein dye disappearance test (objective). A minimum postoperative follow-up of 12 months was an inclusion criterion. Results We studied 22 patients (44 eyes) having a median age of 14.5 years. Anteriorly displaced MCT and lacrimal punctum were noted in 44 eyes (100%), prominent nasal bridge in 20 patients (90.9%), beak sign in 36 eyes (81.8%), and synophyrs in 17 (77.3%) patients. All 44 eyes underwent MCT release with adjunctive punctoplasty (n = 6 eyes) or lower eyelid retractor plication (n = 4 eyes). At a mean follow-up of 12.6 months, 26 eyes (59.1%) showed complete response, i.e., negative FDDT and grade 0 Munk score. Partial response was noted in 14 (31.8%) eyes, i.e., delayed FDDT and reduction of ≥2 grades on Munk score. Conclusion Along with the classic features of CS, beak sign and synophyrs are important diagnostic ophthalmic-facial features of CS. The transverse closure of surgical wounds may provide effective long-term benefits in the medial canthal tendon release procedure.

Does Dysmenorrhea Affect Clinical Features and Long-Term Surgical Outcomes of Patients With Ovarian Endometriosis? A 12-Year Retrospective Observational Cohort Study.

BackgroundTo examine and compare the differences in clinical characteristics and long-term postoperative outcomes of ovarian endometriomas (OMA) patients with and without dysmenorrhea, including data from at least 8 years of postoperative follow-up examinations.MethodsRetrospective analysis of 334 OMA patients, including their demographic and clinical data. Long-term follow-up record was also collected. All laparoscopic cystectomy procedures were performed by the same surgeon at Peking Union Medical College Hospital between January 2009 and April 2013. Patients were divided into the dysmenorrhea and non-dysmenorrhea groups to perform the analysis of their preoperative characteristics, relevant surgical findings, and postoperative outcomes at the follow-up.ResultsOut of 334 OMA patients, 257 (76.9%) patients were allocated to the dysmenorrhea group, while the rest 77 (23.1%) patients were included in the non-dysmenorrhea group. Compared with the dysmenorrhea group, the non-dysmenorrhea group exhibited a reduced proportion of chronic pelvic pain (CPP) (P = 0.003), dyspareunia (P < 0.001), tenesmus (P < 0.001), concurrency of deep infiltrating endometriosis (DIE) (P < 0.001), and adenomyosis (P = 0.032). Preoperative infertility was significantly higher in the dysmenorrhea group (P = 0.001). The mean operating time in the dysmenorrhea vs. the non-dysmenorrhea group was 68.0 vs. 56.0 min (P < 0.001). According to the revised American Fertility Society (rAFS) scoring system, the mean scores of the two groups were 52.1 vs. 44.6 (P = 0.033). During follow-up, the dysmenorrhea group showed a higher rate of disease relapse (P < 0.001). A minimum postoperative follow-up period of 8 years was required to evaluate the pregnancy outcomes. Successful pregnancies were identified in 97/257 (37.7%) cases in the dysmenorrhea group and 36/77(46.8%) cases in the non-dysmenorrhea group (P = 0.157), respectively. Though the dysmenorrhea group had a higher rate of postoperative infertility, differences were not significant between the two groups.ConclusionsCompared with the dysmenorrhea group, OMA patients without dysmenorrhea exhibited lower proportions of CPP, dyspareunia, tenesmus, lower concurrency of DIE and adenomyosis, shorter mean operating time, lower mean rAFS scores, and lower infertility rates. During the long-term follow-up, a lower recurrence rate was observed in the non-dysmenorrhea group. Regarding fertility outcomes, non-dysmenorrhea patients had a higher likelihood of successful pregnancy after surgery. Postoperative management needs to be evaluated separately according to dysmenorrhea pathology.

A Comparison of the Long-Term Surgical Outcomes of Horizontal Strabismus Surgery between Resident Clinic and Private Clinic Patients

ABSTRACTPurposeTo compare the long-term surgical outcomes of patients with horizontal strabismus whose surgery was performed in an outpatient department (OPD) setting (by residents-in-training) to those whose surgery was performed in a private clinic (PC) setting (by staff-ophthalmologists) in the same operating room/institution.MethodsTwo hundred and forty-four patients’ charts who had horizontal strabismus surgeries from January 2007 to 2020 were reviewed retrospectively. A total of 92 patients were operated on by residents and followed in OPD, and 152 patients by staff-surgeons and followed in PC. Demographic data and eye exam parameters were collected. Distance and near deviation (in prism diopters, PD) were extracted and compared between groups at baseline and postoperatively (6 months and yearly for up to 6 years). Success was defined as a postoperative motor alignment of 10PD or less.ResultsThe mean age of the 244 patients was 10.5 ± 11.7 years, with no significant differences between groups. A longer follow-up duration was reported in the PC group (34.9 ± 24.3 months vs 25.3 ± 20.2 months). Patients had similar success rates in both groups in the early postoperative period (6 months and 1 year); however, a higher success rate was observed in the PC group compared to OPD at 3, 5 and 6 years with the following respective values: 72.2% vs 50% (p < .001), 75% vs. 66.7% (p = .02), and 68.6% vs. 66.7% (p = .03). The difference was more pronounced in the esotropia subgroup mostly at 3 years follow-up.ConclusionThis study showed a similar success rate of horizontal strabismus surgery performed in a PC setting by staff surgeons as compared to that performed in an OPD setting by residents at 6 months and 1 year. A significantly higher success rate was observed at long term follow-up (after 2 years) in the PC group compared to the OPD group, possibly related to the difference in compliance with post-operative follow-up management and not to surgery itself.

Long-Term Prognosis of Patients With Anti-N-Methyl-D-Aspartate Receptor Encephalitis Who Underwent Teratoma Removal: An Observational Study.

ObjectiveThis study aimed to evaluate the clinical characteristics and long-term surgical outcomes of patients with anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis with teratoma.MethodsPatients who were admitted to West China Hospital from June 2012 to June 2019 and diagnosed with anti-NMDAR encephalitis were enrolled in the study. Medical records were reviewed prospectively to gather clinical characteristic data. Patients were followed up at long-term every 3 months.ResultsThis study included 192 patients, among whom 21 (10.9%) were detected with having a teratoma. Patients included 20 women, with a mean age of 24.62 ± 7.61 years. Seizure and psychiatric symptoms were the most dominant symptoms in both groups, followed by memory deficits. Central hypoventilation (52.4 vs. 17%, p < 0.001) and decreased consciousness (71.4 vs. 31.3%, p = 0.002) were significantly more frequent in patients with teratoma than in those without. Moreover, the anti-NMDAR antibody titer was higher (p = 0.021) and the baseline modified Rankin scale score was lower (p = 0.004) in patients with teratoma than in those without. First-line immunotherapy was performed in 21 (100%) patients with teratoma and 167 (97.7%) patients without teratoma. All patients with teratoma had the tumor removed. During follow-up, two (9.5%) patients with teratoma and 11 (6.4%) patients without teratoma died, whereas 1 (4.8%) patient with teratoma and 37 (21.6%) patients without teratoma had relapses. Overall, 19 (90.5%) patients with teratoma and 151 (88.3%) patients without teratoma achieved favorable clinical outcomes at the final follow-up.ConclusionsWith early detection and removal of teratoma, most patients with anti-NMDAR encephalitis and teratoma achieved a favorable long-term prognosis.

Outcomes after Surgical Treatment of Metastatic Disease in the Adrenal Gland; Valuable for the Patient?

Simple SummaryAdrenal glands are common dissemination sites for metastases of various solid tumors. The rapid development of new treatment strategies, such as targeted therapy and immunotherapy for different cancer types, has led to increased metastatic adrenalectomies. Therefore, clear communication between oncologists and adrenal gland specialists has become increasingly important to outweigh surgical risks versus oncological advantages of adrenalectomies in these patients. This study assesses trends in diagnosis, type of surgery, and short-term and long-term surgical outcomes of patients who underwent metastatic adrenalectomy. We included a total of 95 patients with an adrenal metastasis of non-adrenal primary tumors, most often colorectal or lung cancer, who underwent (minimal invasive) adrenalectomy. 37.9% of the patients experienced one or more complications after adrenalectomy. Within our patient cohort, an increased demand for metastatic adrenalectomy was observed over the past years, which might be associated with the rise of targeted- and immunotherapy. Our data aims to assist multidisciplinary teams with weighing the pros and cons of resection of the metastasized adrenal gland of cancer patients.The adrenal glands are common dissemination sites for metastasis of various solid tumors. Surgical treatment is often recommended because targeted therapies and immunotherapy are frequently ineffective for adrenal metastasis. We report the experience with short-term and long-term surgical outcomes of patients undergoing surgery for adrenal metastasis in two hospitals. A retrospective, multicenter study was performed to analyze patient characteristics, tumor-related data, perioperative outcomes, and oncological outcomes. Postoperative complications that occurred within 30 days were scored according to the Clavien Dindo classification. Metastatic adrenalectomy was performed in 95 patients. We observed an increase from an average of 3 metastatic adrenalectomies per year between 2001–2005 to 10 between 2015–2019. The most frequent underlying malignancies were colorectal and lung cancer. In 55.8%, minimal invasive adrenalectomy was performed, including six conversions to open surgery. A total of 37.9% of patients had postoperative complications, of which ileus or gastroparesis, wound problems, pneumonia, and heart arrhythmias were the most occurring complications. Improved cancer care has led to an increased demand for metastatic adrenalectomy over the past years. Complication rates of 37.9% are significant and cannot be neglected. Therefore, multidisciplinary teams should weigh the decision to perform metastatic adrenalectomy for each patient individually, taking into account the drawbacks of the described morbidity versus the potential benefits.

Long-Term Surgical Outcomes of Liver Resection for Hepatocellular Carcinoma in Patients With HBV and HCV Co-Infection: A Multicenter Observational Study.

BackgroundHepatocellular carcinoma (HCC) is one of the most serious consequences of chronic hepatitis B virus (HBV) or hepatitis C virus (HCV) infection. This study sought to investigate long-term outcomes after liver resection for HCC among patients with HBV/HCV co-infection (HBV/HCV-HCC) compared with patients with HBV infection (HBV-HCC).MethodsPatients who underwent curative-intent liver resection for HCC were identified from a multicenter Chinese database. Using propensity score matching (PSM), patients with HBV/HCV-HCC were matched one-to-one to patients with HBV-HCC. Overall survival (OS) and recurrence-free survival (RFS) were compared between the two groups before and after PSM.ResultsAmong 2,467 patients identified, 93 (3.8%) and 2,374 (96.2%) patients had HBV/HCV-HCC and HBV-HCC, respectively. Compared with patients with HBV-HCC, patients with HBV/HCV-HCC were older, have poorer liver-related characteristics but better tumor-related characteristics. PSM created 88 pairs of patients with comparable liver- and tumor-related characteristics (all P > 0.2). In the PSM cohort, the 3- and 5-year RFS rates in patients with HBV/HCV-HCC were 48.3% and 38.9%, which were significantly poorer than patients with HBV-HCC (61.8% and 49.2%, P = 0.037). Meanwhile, the 3- and 5-year OS rates in patients with HBV/HCV-HCC were also poorer than patients with HBV-HCC (65.4% and 51.1% vs. 73.7% and 63.0%), with a difference close to be significant between them (P = 0.081).ConclusionComparing to patients with HBV-HCC, liver resection resulted in relatively poorer long-term surgical outcomes in patients with HBV/HCV-HCC.

Long-term surgical outcomes of liver resection for hepatocellular carcinoma in patients with hepatitis B virus and hepatitis C virus co-infection: A multicenter observational study

Hepatocellular carcinoma (HCC) is one of the most serious consequences of chronic hepatitis B virus (HBV) or hepatitis C virus (HCV) infection. This study sought to investigate long-term outcomes after liver resection for HCC among patients with HBV/HCV co-infection (HBV/HCV-HCC) compared with patients with HBV infection (HBV-HCC).

Long-term follow-up of surgical outcomes for patients with Wilms tumor and neuroblastoma.

There are minimal data on long-term surgical outcomes of patients who have undergone resection for Wilms tumor (WT) and neuroblastoma (NB). A retrospective review of patients in a long-term survivor clinic between the years 1967 and 2016 in a pediatric tertiary care hospital (>5 years posttreatment) was performed. Eighty-six survivors of WT and 86 survivors of NB who had ongoing follow-up in the survivors' clinic were identified. The median age at diagnosis was 2.5 years (range, 0.4-15.7 years) with a mean follow-up of 22.3 years (±10.4 years) for WT. The median age at diagnosis for patients with NB was 0.9 years (range, 0.1-8.6 months); mean follow-up of 21.7 years (±7.9 years). Twelve patients with WT (14.0%) had at least 1 repeat laparotomy, 11.1% for bowel obstruction, at a median of 3 months from initial surgery. Twelve patients (14.0%) with NB required laparotomy and 8.1% for bowel obstruction, at a median of 12 years after initial surgery. The incidence of hypertension in patients with WT who had undergone nephrectomy was not outside of population norms. Patients who underwent thoracotomy for a NB have a higher incidence of scoliosis and Horner syndrome. Small bowel obstruction requiring laparotomy is significantly higher than the literature norms for both tumor patient populations and typically occurs in the early postoperative period for patients with WT and remotely in patients with NB. The long-term surgical complications of patients who underwent resection for NB and WT clearly merit follow-up and patient education within multidisciplinary long-term survivorship clinics.

Necrotising Pancreatitis- A Cross-sectional Study on Surgical Outcomes of Pancreatic Necrosectomy

Introduction: Necrotising Pancreatitis (NP) is the severe form of acute pancreatitis accounting for significant mortality (15- 40%), morbidity (~25%) and has significant health costs. The traditional management of infected necrosis has centered on open surgical debridement which is accompanied by significant risk of stress, organ failure and complications. Short-term and long-term functional outcomes after operative treatment of NP have not been studied extensively. Aim: To evaluate the short-term and long-term surgical outcomes in patients undergoing surgery for NP. Materials and Methods: This was a cross-sectional study of patients who underwent surgery for NP conducted at Manipal Hospital, Bangalore between June 2009 to March 2016. The electronic records pertaining to such patients were retrieved. Various surgeries done were grouped. Surgical complications and short-term outcomes like new onset organ failure, Surgical Site Infection (SSIs), haemorrhage, bowel fistula, re-explorations, and requirement of additional procedures, hospital stay and the mortality were studied by hospital data. Long-term outcomes like endocrine/exocrine insufficiency, weight loss, recurrent pancreatitis, incision hernia were studied by prospective data collected from telephonic interview; questionnaires in addition to data collected as and when patient gets admitted and in Outpatient Department (OPD) during follow-up. A comparison with different surgical techniques like laparoscopy, open necrosectomy, Video assisted necrosectomy was made. Statistical analyses were performed by STATA 11.2 (College Station TX USA). Mann-Whitney test were used to find the significance difference between the length of stay and Intensive Care Unit (ICU) stay with the groups and it is expressed as mean and standard deviation, Chi-square test has been used to measure the association between different clinical variables. p&lt;0.05 was considered as statistically significance. Results: Forty six patients underwent surgical treatment during the study period. Patients’ age ranged from 25 to 75 years (median age- 44 years). Median postoperative ICU stay was 12 days (range of 01- 32 days). The mean follow-up was 3.5 years. The overall mortality rate was 26% (12 patients). The mortality rates between laparatomy (33%) and minimally invasive necrosectomy (23%) groups were not significantly different (p=0.436). Secondary diabetes mellitus was observed in 18 (40%) and exocrine insufficiency in 8 (18%) of patients. The other long-term complications were recurrent pancreatitis in 7 (15%), biliary stricture 3 (6%) and incisional hernia in 3 (6%). Conclusion: Mortality rate, organ failure rates and median ICU admission rate were similar across all surgical techniques though there was a trend of overall reduced complication rate. A long-term and close follow-up is advised in these patients for the late complications to be identified and treated.

Influences of Dementia on Long-Term Surgical Outcomes in Older Adults After Hip Fracture

Older adults with dementia are more prone to have adverse health outcomes following hip fracture surgery. However, individuals with dementia and hip fracture are older and have more co-morbidities; these baseline differences can bias estimates of the influence of dementia. This study aims to investigate how dementia influences disposition, mortality rates and readmission rates at 365 days after hip surgery in older adults over age 65, after accounting for baseline factors such as socioeconomic status, health behaviors, co-morbidities, and type of hip fracture repair. A cohort of 1172 patients who had hip fracture surgery between October 2015 and December 2018 was extracted from electronic health records; among those, 376 had a diagnosis of dementia. Inverse probability of treatment weighting using propensity scores method was used to reduce the influence of factors that may confound the relationship between dementia status and hip surgery outcomes. Logistic regression was applied to estimate influences on discharge disposition and Cox proportional hazards model for one-year mortality. To account for competing risk of death, a Fine and Gray regression model was used to calculate subdistribution hazard ratios of readmission. Disparities in long-term surgical outcomes in patients with dementia were found. Results show that dementia was a significant predictor for being discharged to facilities (OR=1.92, 95% CI 1.09, 3.39, p=.025), death (HR=1.98, 95% CI 1.50-2.62, p<.0001) and being readmitted within one year (HR=1.31, 95% CI 1.15-1.50, p<.0001). These findings call for more efforts in developing effective multidisciplinary perioperative assessments and rehabilitation for patients with dementia.

Viral elimination is essential for improving surgical outcomes of hepatitis C virus-related hepatocellular carcinoma: Multicenter retrospective analysis.

AimThe impact of sustained virologic response (SVR) on surgical outcomes for patients with hepatitis C virus (HCV)‐related hepatocellular carcinoma (HCC) remains controversial. This study aimed to evaluate the influence of SVR on long‐term surgical outcomes after hepatectomy.MethodsThis multicenter study included 504 patients who underwent curative resection for HCV‐related HCC. Patients with a history of HCC treatment, HBV infection, poor liver function, and tumor with major vascular invasion were excluded. Long‐term surgical outcomes (overall survival [OS] and recurrence‐free survival [RFS]) among patients who achieved SVR before hepatectomy (Pre‐SVR group: 58 patients), after hepatectomy (Post‐SVR group: 54 patients), and without SVR (Non‐SVR group: 186 patients) were compared after adjusting for 13 confounding factors. Using the surgically resected specimens, comparison of the pathological changes in liver fibrosis between the first and second hepatectomy were analyzed.ResultsPatients with SVR were younger, had better liver function, and less liver fibrosis compared to patients without SVR. Propensity score‐matched OS and RFS were significantly better in Pre‐SVR group than Non‐SVR group (P = .029 and P = .009, respectively). Inverse probability‐weighted OS and RFS were also significantly better in the Post‐SVR group (P = .001 and P = .021, respectively) than in the Non‐SVR group. Histopathological evaluation revealed that only the patients with SVR had regression of liver fibrosis (P < .05).ConclusionAchievement of SVR before or after hepatectomy is essential for improving long‐term surgical outcomes in patients with HCV‐related HCC.
