Factors affecting fat myringoplasty in elderly patients with chronic otitis media: A case control study

BackgroundWe compared and analyzed the surgical results of fat myringoplasty between elderly and young adult patients with chronic otitis media. We also investigated whether underlying diseases and other factors impact the surgical outcome.MethodsWe retrospectively reviewed the data of 141 patients who underwent fat myringoplasty for chronic otitis media for five years. They were compared by age, sex, underlying disease, perforation size, pre- and postoperative pure tone audiometry, postoperative otorrhea, postoperative re-perforation, and cause of re-perforation.ResultPostoperative re-perforation was more common in the elderly group, albeit with no significant difference (p = 0.072). The factors affecting re-perforation were insufficient fat graft (44.4%), postoperative infection (33.3%), and nasal blowing (22.2%). Our findings revealed no significant association between preoperative perforation size and re-perforation (p = 0.391). Additionally, we found no significant relationship between hypertension and re-perforation (p > 0.99), nor between age group and postoperative infection (p = 0.488). Diabetes was also not significant (p = 0.640). Following surgery, both groups exhibited a significant improvement in hearing.ConclusionAlthough age and underlying conditions play significant roles in the healing process, our results suggest that external factors such as infection, nasal blowing, cough, and insufficient grafted fat tissue have a similarly significant impact on surgical outcomes in elderly patients with COM as they do in adults. In conclusion, the decision to perform surgery in elderly patients with COM should be based on a comprehensive assessment of the patient’s overall health status, hearing, use of hearing aids, and the indications for surgery.

Frailty Increases Morbidity and Mortality in Patients Undergoing Oncological Liver Resections: A Systematic Review and Meta-analysis

BackgroundConsidered to reflect a patients’ biological age, frailty is a new syndrome shown to predict surgical outcomes in elderly patients. In view of the increasing age at which patients are proposed oncological liver surgery and the morbidity associated with it, we attempted to perform a systematic review and meta-analysis to compare morbidity and mortality between frail and nonfrail patients after liver resections.MethodsThe study was registered with PROSPERO. A systematic search of PubMed and EMBASE databases was performed for all comparative studies examining surgical outcomes after liver resections between frail and nonfrail patients.ResultsTen studies were included based on the selection criteria with a total of 71,102 patients, split into two groups: frail (n = 17,167) and the control group (n = 53,928). There were more elderly patients with a lower preoperative albumin level in the frail group (p = 0.02, p = 0.001). Frail patients showed higher rates of morbidity with more major complications and a higher incidence of postoperative liver failure (p < 0.001). Mortality (p < 0.001) and readmission rate (p = 0.021) also was higher in frail patients.ConclusionsFrailty seems to be a solid predictive risk factor of morbidity and mortality after liver surgery and should be considered a selection criterion for liver surgery in at-risk patients.

Effects of ultrasound-guided lumbar plexus and sacral plexus block combined with general anesthesia on the anesthetic efficacy and surgical outcomes in elderly patients undergoing intertrochanteric fracture surgery: a randomized controlled trial

BackgroundSurgery for intertrochanteric fractures in elderly patients is challenging due to the risk of severe pain and significant stress responses. We investigated the effects of a combined approach of ultrasound-guided lumbar plexus and sacral plexus block with general anesthesia on anesthetic efficacy and surgical outcomes in these patients.MethodsA randomized controlled trial was conducted involving 150 elderly patients, divided into two groups: the combined anesthesia group (receiving ultrasound-guided lumbar plexus and sacral plexus block along with general anesthesia) and the general anesthesia alone group. Outcome measures included hemodynamic parameters, postoperative pain levels (VAS scores), postoperative recovery times, and incidence of adverse reactions.ResultsIn the combined anesthesia group, the patients had more stable intraoperative hemodynamics, lower postoperative VAS scores at 1, 3, and 6 h, and faster recovery times (eye-opening upon command and return of respiratory function) compared to the general anesthesia group. Furthermore, the incidence of adverse reactions was significantly lower in the combined anesthesia group.ConclusionsUltrasound-guided lumbar plexus and sacral plexus block combined with general anesthesia enhanced the anesthetic efficacy and improved surgical outcomes in elderly patients undergoing intertrochanteric fracture surgery.

Relevance of sarcopenia in elderly patients undergoing surgery for oral squamous cell carcinoma

In the elderly population there is increasing evidence that frailty predicts adverse outcomes better than chronological age. Sarcopenia is an important component of frailty. This study aimed to establish the relevance of sarcopenia in elderly patients with oral squamous cell carcinoma (OSCC) undergoing surgery. This retrospective, single-centre, cohort study included patients over the age of 75 years who were diagnosed with OSCC between 2007 and 2016. Cross-sectional imaging of the neck was used to predict the Skeletal Muscle Index (SMI) using validated equations. Based on established thresholds, patients were categorised as having either a normal or low SMI, indicative of sarcopenia. Sixty-nine patients met the inclusion criteria. Patients with a low SMI had a longer length of stay (16.9 days vs 9.8 days, p = 0.030); they had more severe complications, defined as Clavien-Dindo grade IIIb or higher (17.6% vs 4.0%, p = 0.042); and their mean Comprehensive Complication Index (CCI) was also higher (14.1 vs 4.7, p = 0.051). Furthermore, 2/34 patients in the low SMI group died within 30 days of surgery compared with none in the normal SMI group (5.9% vs 0%, p = 0.503). Whilst patients with a low SMI who underwent surgery had lower five-year overall survival, the difference was not statistically significant. This study shows that sarcopenia negatively influences surgical outcomes in elderly patients. Routine measurement of SMI could be an indication for a comprehensive geriatric assessment (CGA).

Effects of Bone Cross-Link Bridging on Fracture Mechanism and Surgical Outcomes in Elderly Patients with Spine Fractures.

This study adopted a cross-sectional study design. This study was designed to investigate the effects of bone cross-link bridging on fracture mechanism and surgical outcomes in vertebral fractures using the maximum number of vertebral bodies with bony bridges between adjacent vertebrae without interruption (maxVB). The complex interplay of bone density and bone bridging in the elderly can complicate vertebral fractures, necessitating a better understanding of fracture mechanics. We examined 242 patients (age >60 years) who underwent surgery for thoracic to lumbar spine fractures from 2010 to 2020. Subsequently, the maxVB was classified into three groups: maxVB (0), maxVB (2-8), and maxVB (9-18), and parameters, including fracture morphology (new Association of Osteosynthesis classification), fracture level, and neurological deficits were compared. In a sub-analysis, 146 patients with thoracolumbar spine fractures were classified into the three aforementioned groups based on the maxVB and compared to determine the optimal operative technique and evaluate surgical outcomes. Regarding the fracture morphology, the maxVB (0) group had more A3 and A4 fractures, whereas the maxVB (2-8) group had less A4 and more B1 and B2 fractures. The maxVB (9-18) group exhibited an increased frequency of B3 and C fractures. Regarding the fracture level, the maxVB (0) group tended to have more fractures in the thoracolumbar transition region. Furthermore, the maxVB (2-8) group had a higher fracture frequency in the lumbar spine area, whereas the maxVB (9-18) group had a higher fracture frequency in the thoracic spine area than the maxVB (0) group. The maxVB (9-18) group had fewer preoperative neurological deficits but a higher reoperation rate and postoperative mortality than the other groups. The maxVB was identified as a factor influencing fracture level, fracture type, and preoperative neurological deficits. Thus, understanding the maxVB could help elucidate fracture mechanics and assist in perioperative patient management.

Intraoperative pleth variability index-based fluid management therapy and gastrointestinal surgical outcomes in elderly patients: a randomised controlled trial

BackgroundIntraoperative goal-directed fluid therapy (GDFT) has been reported to reduce postoperative complications of patients undergoing major abdominal surgery. The clinical benefits of pleth variability index (PVI)-directed fluid management for gastrointestinal (GI) surgical patients remain unclear. Therefore, this study aimed to evaluate the impact of PVI-directed GDFT on GI surgical outcomes in elderly patients.MethodsThis randomised controlled trial was conducted in two university teaching hospitals from November 2017 to December 2020. In total, 220 older adults undergoing GI surgery were randomised to the GDFT or conventional fluid therapy (CFT) group (n = 110 each). The primary outcome was a composite of complications within 30 postoperative days. The secondary outcomes were cardiopulmonary complications, time to first flatus, postoperative nausea and vomiting, and postoperative length of stay.ResultsThe total volumes of fluid administered were less in the GDFT group than in the CFT group (2.075 L versus [vs.] 2.5 L, P = 0.008). In intention-to-treat analysis, there was no difference in overall complications between the CFT group (41.3%) and GDFT group (43.0%) (odds ratio [OR] = 0.935; 95% confidence interval [CI], 0.541–1.615; P = 0.809). The proportion of cardiopulmonary complications was higher in the CFT group than in the GDFT group (19.2% vs. 8.4%; OR = 2.593, 95% CI, 1.120–5.999; P = 0.022). No other differences were identified between the two groups.ConclusionsAmong elderly patients undergoing GI surgery, intraoperative GDFT based on the simple and non-invasive PVI did not reduce the occurrence of composite postoperative complications but was associated with a lower cardiopulmonary complication rate than usual fluid management.Trial registrationThis trial was registered with the Chinese Clinical Trial Registry (ChiCTR-TRC-17012220) on 1 August 2017.

Evaluation of surgical outcomes in elderly patients with rib fractures: A single-centre propensity score matching study.

Rib fractures are the most common injuries in chest trauma. Compared with younger patients, elderly patients with rib fracture have a higher incidence of complications and mortality. A retrospective study was conducted to investigate the effect of internal fixation compared with conservative treatment on the outcome of rib fracture in elderly patients. We used a 1:1 propensity score matching method to perform a retrospective analysis of 703 elderly patients with rib fractures treated in the Thoracic Surgery Department of Beijing Jishuitan Hospital between 2013 and 2020. After matching, the length of hospital stay, death, symptom relief and rib fracture healing were compared between the surgery and the control group. The study included 121 patients receiving SSRF in the surgery group and 121 patients receiving conservative treatment in the control group. The length of hospital stay in the surgery group was significantly longer than that in the conservative group (11.39d vs. 9.48d, p = 0.000). After 9 months of follow-up, the fracture healing rate in the surgery group was significantly higher than that in the control group (96.67% vs. 88.89%, p = 0.020). The fracture healing time (p = 0.000), improvement in pain score (p = 0.000) and duration of pain medication use (p = 0.000) were also significantly better in the surgery group than in the control group. Compared with conservative treatment, surgical treatment can prolong hospital stay to some extent. However, it has the advantages of more rapid healing and lessened pain. For rib fractures in elderly individuals, surgical treatment is a safe and effective option under strict surgical indications and is recommended.

Clinical and survival outcomes of colectomy for transverse colon cancer in elderly patients.

It remains controversial whether elderly patients with transverse colon cancer present worse prognoses. Our study utilized evidence from multi-center databases to evaluate the perioperative and oncology outcomes of radical resection of colon cancer in elderly and nonelderly patients. In this study, we analyzed 416 patients with transverse colon cancer who underwent radical surgery from January 2004 to May 2017, including 151 elderly (aged ≥ 65 years) and 265 nonelderly (aged < 65 years) patients. We retrospectively compared the perioperative and oncological outcomes between these 2 groups. The median follow-up in the elderly and nonelderly groups was 52 and 64 months, respectively. There were no significant differences in the overall survival (OS) (P = .300) and disease-free survival (DFS) (P = .380) between the elderly and nonelderly groups. However, the elderly group had longer hospital stays (P < .001), a higher complication rate (P = .027), and fewer lymph nodes harvested (P = .002). The N classification and differentiation were significantly associated with OS based on univariate analysis, and the N classification was an independent prognostic factor for OS based on multivariate analysis (P < .05). Similarly, the N classification and differentiation were significantly correlated with the DFS based on univariate analysis. However, multivariate analysis indicated that the N classification was an independent prognostic factor for DFS (P < .05). In conclusion, the survival and surgical outcomes in elderly patients were similar to nonelderly patients. The N classification was an independent factor for OS and DFS. Even though elderly patients with transverse colon cancer present a higher surgical risk than nonelderly patients, performing radical resection in elderly patients can be an appropriate choice for treatment.

Clinical characteristics, brain computerized tomography scan and surgical outcome in elderly patients with chronic subdural hematoma

Objective: To determine clinical characteristics, computer tomography brain imaging, and surgical outcome for elderly patients with chronic subdural hematoma (CSDH). Subject and method: A cross-sectional, descriptive, and retrospective study was conducted on 74 elderly patients diagnosed with CSDH and operated at 108 Military Central Hospital from June 2020 to June 2021. Result: Mean age was 75.2 years; male/female ratio was 3.93/1, the most common cause was traumatic brain injury (49%). The common presenting symptoms of CSDH were altered mental state (70.9%) and headache (68.9%), followed by cognitive impairment (54.1%), hemiparesis (21.6%), hematoma maximal thickness and midline shift were associated with a higher rate of hemiparesis in CSDH patients (p&lt;0.05); The percentage of patients with GCS score ≥ 13 was 90.5%. The portion of unilateral on the brain CT was 78.4%. The most common densities of CSDH obtained from CT imaging was isodense (accounting for 54.0%); followed by hypodense (20.3%), high-density (17.6%), and mixed-density (8.1%); The most common complication of burr hole technique was pneumocephalus (accounting for 8.1%); recurrence of CSDH (5.4%). The Glasgow outcome scale (GOS) 4-5 was 89.7% within 3 months. Conclusion: Chronic subdural hematoma was one of the most common diseases in neurosurgery. The burr hole drainage technique was safe and effective.

Среднесрочные результаты лечения тяжелой деформации переднего отдела стопы у пациентов пожилого возраста

Severe complex deformities of the forefoot in elderly patients with no rheumatoid arthritis result in the pronounced decrease in quality of life, chronic pain, reduced mobility, failure to get shoes for everyday use, exacerbation of the concomitant somatic diseases. The use of conventional joint preservation techniques in such patients often leads to the deformity relapse, persistent pain, and the need for revision surgery that is often impossible due to worsening of the patients' general somatic status and local functional status. The study was aimed to improve surgical outcomes in elderly patients with no rheumatoid arthritis who had severe forefoot deformities. The prospective cohort study that involved allocation to the retrospective group for comparison of surgical outcomes in 65 patients was carried out in 2016–2019. The results obtained before and after surgery were assessed using the FFI, AOFAS Hallux, and AOFAS Lesser Toes scores. The Maryland scores were used to assess the outcomes during the postoperative period. The study revealed significant differences in treatment outcomes based on the AOFAS Hallux (p = 0.0001), AOFAS Lesser Toes (p = 0.0001), FFI (p = 0.0001), and Maryland (p = 0.0001) scores. In view of the elderly patients' specific nature, the radical surgical techniques that do not ensure joint preservation may be considered as effective and predictable methods of correction aimed at reducing the rate of revision surgeries. These techniques represent a one-step method to improve the quality of life of elderly patients.

Analysis of the Surgical Outcomes in Elderly Patients with Hip Fractures Combined with Hemiplegia.

ObjectiveThis study aimed to investigate the surgical outcomes in elderly (age ≥65) patients with hip fractures combined with hemiplegia and compare them with the surgical outcomes in elderly patients with hip fractures but no hemiplegia.MethodsA total of 761 elderly patients with hip fractures who were treated between January 2013 and December 2019 were enrolled in this study using a retrospective study design. The patients were divided into two groups: a hemiplegia group (77 cases, 10.1%) and a non-hemiplegia group (684 cases, 89.9%). Length of hospital stay, postoperative complications, 30-day and one-year mortalities, and one-year functional status were compared between the two groups.ResultsThe average length of hospital stay in the hemiplegia group (13.51 ± 10.17 days) was longer than in the non-hemiplegia group (12.60 ± 7.83 days), but the difference was not statistically significant (P = 0.354). The incidence of postoperative complications in patients with hemiplegia (28.6%, 22/77) was higher than in patients without hemiplegia (15.4%, 105/684), and the difference was statistically significant (P = 0.003). The 30-day and one-year mortalities in the hemiplegia group were higher than in the non-hemiplegia group (30 days after surgery: 10.4%, 8/77 vs 4.5%, 31/684; one year after surgery: 29.9%, 23/77 vs 15.2%, 104/684), and the difference was statistically significant (30 days after surgery: P = 0.027; one year after surgery: P = 0.001). One year after surgery, the average activity of daily living score was 56.02 ± 9.63 in the hemiplegia group and 76.89 ± 8.40 in the non-hemiplegia group, and the difference was statistically significant (P = 0.000).ConclusionHemiplegia can increase the incidence of postoperative complications and 30-day and one-year mortalities in patients with hip fractures.

The Association Between Visceral Obesity and Postoperative Outcomes in Elderly Patients With Colorectal Cancer

BackgroundThe impact of visceral obesity on the postoperative complications of colorectal cancer in elderly patients has not been well studied. This study aims to explore the influence of visceral obesity on surgical outcomes in elderly patients who have accepted a radical surgery for colorectal cancer.MethodsPatients aged over 65 year who had undergone colorectal cancer resections from January 2015 to September 2020 were enrolled. Visceral obesity is typically evaluated based on visceral fat area (VFA) which is measured by computed tomography (CT) imaging. Univariate and multivariate analyses were performed to analyze parameters related to short-term outcomes.ResultsA total of 528 patients participated in this prospective study. Patients with visceral obesity exhibited the higher incidence of total (34.1% vs. 18.0%, P < 0.001), surgical (26.1% vs. 14.6%, P = 0.001) and medical (12.6% vs. 6.7%, P = 0.022) complications. Based on multivariate analysis, visceral obesity and preoperative poorly controlled hypoalbuminemia were considered as independent risk factors for postoperative complications in elderly patients after colorectal cancer surgery.ConclusionsVisceral obesity, evaluated by VFA, was a crucial clinical predictor of short-term outcomes after colorectal cancer surgery in elderly patients. More attentions should be paid to these elderly patients before surgery.

Central Sarcopenia, Frailty and Comorbidity as Predictor of Surgical Outcome in Elderly Patients with Degenerative Spine Disease.

ObjectivePeople are living longer and the elderly population continues to increase. The incidence of degenerative spinal diseases (DSDs) in the elderly population is quite high. Therefore, we are facing more cases of DSD and offering more surgical solutions in geriatric patients. Understanding the significance and association of frailty and central sarcopenia as risk factors for spinal surgery in elderly patients will be helpful in improving surgical outcomes. We conducted a retrospective cohort analysis of prospectively collected data to assess the impact of preoperative central sarcopenia, frailty, and comorbidity on surgical outcome in elderly patients with DSD. MethodsWe conducted a retrospective analysis of patients who underwent elective spinal surgery performed from January 1, 2019 to September 30, 2020 at our hospital. We included patients aged 65 and over who underwent surgery on the thoracic or lumbar spine and were diagnosed as DSD. Central sarcopenia was measured by the 50th percentile of psoas : L4 vertebral index (PLVI) using the cross-sectional area of the psoas muscle. We used the Korean version of the fatigue, resistance, ambulation, illnesses, and loss of weight (K-FRAIL) scale to measure frailty. Comorbidity was confirmed and scored using the Charlson Comorbidity Index (CCI). As a tool for measuring surgical outcome, we used the Clavien-Dindo (CD) classification for postoperative complications and the length of stay (LOS). ResultsThis study included 85 patients (35 males and 50 females). The mean age was 74.05±6.47 years. Using the K-FRAIL scale, four patients were scored as robust, 44 patients were pre-frail and 37 patients were frail. The mean PLVI was 0.61±0.19. According to the CD classification, 50 patients were classified as grade 1, 19 as grade 2, and four as grade 4. The mean LOS was 12.35±8.17 days. Multivariate stepwise regression analysis showed that postoperative complication was significantly associated with surgical invasiveness and K-FRAIL scale. LOS was significantly associated with surgical invasiveness and CCI. K-FRAIL scale showed a significant correlation with CCI and PLVI. ConclusionThe present study demonstrates that frailty, comorbidity, and surgical invasiveness are important risk factors for postoperative complications and LOS in elderly patients with DSD. Preoperative recognition of these factors may be useful for perioperative optimization, risk stratification, and patient counseling.

Physical activities and surgical outcomes in elderly patients with acute type A aortic dissection.

Although elderly patients undergoing surgery for acute type A aortic dissection (ATAAD) is increasing, their physical activities are not fully understood. We report the physical activities and surgical outcomes in elderly patients who underwent ATAAD. From 2009 to 2019, 103 consecutive patients underwent surgery for ATAAD at our institution. Surgical outcomes along with pre- and postoperative physical activities in 52 elderly patients (≥70 years old) were compared with those in 51 younger patients (<70 years old). Postoperative walking difficulty was defined as taking ≥30 days to regain the ability to walk 200 m postoperatively or as the inability to walk at discharge. It took longer for elderly patients to regain the ability to walk 100 or 200 m postoperatively. ROC analysis revealed the AUC of the duration for walking 200 m postoperatively as a prognostic indicator for late deaths was 0.878, with the highest accuracy at 30 days (sensitivity = 83.3%, specificity = 91.8%). Hospital mortality within 30 days was 3.8%, and 1-, 3-, and 5-years survival rates were 92%, 84.7%, 84.7%, respectively, for elderly patients, with no significant differences between groups. Cox proportional hazard analysis showed postoperative walking difficulty was an independent risk factor for late mortality in all cohorts (p = .017). Elderly patients undergoing surgical ATAAD repair showed acceptable surgical outcomes. However, they were more likely to decrease their physical activities postoperatively. Postoperative difficulty in walking was an independent risk factor for the late mortality in patients with ATAAD.

Post-operative deep vein thrombosis in patients over sixty years of age diagnosed with closed distal femur fractures undergoing open reduction internal fixation.

New-onset deep vein thrombosis (DVT) reportedly affects prognosis and surgical outcomes of elderly patients. However, its effect on distal femur fractures (DFFs) remains unclear. We aimed to address the epidemiological characteristics and the associated predictors for post-operative DVT in patients with closed DFFs over age 60 years old. We designed a prospective cohort trial at our hospital between October 2018 and June 2020 and recruited consecutive 140 patients over age 60 years diagnosed with closed DFFs. We examined location and prognosis of postoperative DVT and then conducted a three month follow-up. We used Duplex ultrasonography (DUS) to diagnose DVT in all patients and then classified the subjects into DVT and non-DVT groups. We further classified DVTs into proximal, distal, and mixed thromboses and then performed Whitney U test or t test, receiver operating characteristic (ROC) curve analysis, Chi-square test, and multiple logistic regression analysis to confirm the adjusted factors of post-operative DVT. We found a 35% (n = 49) overall incidence of post-operative DVTs, which occurred 5.7 days following open reduction internal fixation (ORIF). Among patients with post-operative DVTs, 53.1% (n = 26) and 10.2% (n = 5) were distal and proximal thromboses, respectively. Additionally, peroneal veins were the most common DVT sites (71.4%, n = 35). Multivariate analysis revealed that venous thrombosis at admission (odds ratio [OR], 4.619; 95% confidence interval [CI]: 2.072-10.299; P = 0.000), operation duration over 195 minutes (OR, 3.289; 95% CI, 1.155-9.370; P = 0.026), intra-operative blood loss over 325 mL (OR, 2.538; 95% CI, 1.047-6.155; P = 0.039) were the three independent risk factors of post-operative DVT. Unified antithrombotic agents after diagnosis showed that 16.3% (n = 8) of DVTs were completely recanalized, 12.6 days after first diagnosis. Our findings indicate a strong association between venous thrombosis at admission, the longer operation duration, and considerable intra-operative blood loss with high risk of post-operative DVTs in patients over age 60 years with closed DFFs. Preventive approaches for postoperative DVTs should seek to shorten operation duration and reduce intra-operative blood loss.

Risk factors of elderly patients with postoperative delirium following major abdominal surgery for cancer.

Postoperative delirium (POD) is a common complication in elderly patients after major abdominal surgery for cancer. Although POD is related with a poor outcome, there have not been many reports about POD after abdominal surgery in Korea. The aims of study were to analyze the characteristics and surgical outcomes of elderly patients with POD and to identify the risk factors of POD. From November 2016 to January 2019, we prospectively enrolled 63 patients who were aged ≥75 years and underwent major abdominal surgery for cancer. POD was daily assessed for up to 10 days postoperatively with the Confusion Assessment Method and a validated chart review. POD occurred in eight patients (12.7%). Univariate analysis showed that the occurrence of POD was related to sodium <135 mEq/L (P=0.037), combined resection (P=0.023), longer surgery/anesthesia time (P=0.023 and P=0.037, respectively), increased blood loss (P=0.004), postoperative admission to intensive care unit (ICU) (P=0.023), and duration of Foley catheter (P=0.011), however, multivariate analysis identified no significant risk factors of POD. There was no difference in postoperative outcomes such as hospital stay, mortality, reoperation, and morbidity between patients with POD and without POD. Elderly patients with hyponatremia, combined resection, longer operation/anesthesia time and admission to ICU had tendencies to develop POD after major abdominal surgery. Surgeons should pay more attention to prevent POD, and a large-scale prospective study is needed to identify the risk factors of POD.

Surgical outcomes of elderly patients aged more than 80\u2009years with distal radius fracture: comparison of external fixation and locking plate

BackgroundTo compare the outcomes after surgical intervention, including external fixation (EF) with the optional addition of K-pins or open reduction and internal fixation (ORIF) with a volar locking plate (VLP), in patients with distal radius fracture aged > 80 years.MethodsWe reviewed 69 patients with a distal radius fracture aged > 80 years who treated under surgical intervention from 2011 to 2017 retrospectively. Their demographic data and complications were recorded. Preoperative, postoperative, and last follow-up plain films were analyzed. The functional outcomes of wrist range of motion were also evaluated.Results41 patients were treated with EF with the optional addition of K-pins, while 28 patients were treated with ORIF with a VLP. The radiological parameters, including ulnar variance and radial inclination, at the last follow-up were significantly more acceptable in the VLP group (p = 0.01, p = 0.03, respectively). The forearm supination was significantly better in patients treated with VLP (p = 0.002). The overall incidence of complications was lower in the VLP group (p = 0.003).ConclusionVLP provides better radiological outcomes, wrist supination and lower complication rates than EF. Therefore, although EF is still widely used because of its acceptable results and easy application, we recommend VLP as a suitable treatment option for distal radius fracture in the geriatric population aged > 80 years.

Long-term outcomes of colorectal cancer surgery for elderly patients: a propensity score-matched analysis.

To investigate the effect of old age on the perioperative, short-term, and long-term surgical outcomes of elderly patients undergoing curative surgery for colorectal cancer (CRC). The subjects of this retrospective study were 526 patients who underwent curative resections for stage I-III CRC between March 2005 and March 2016. We divided the patients into a young group (< 75years old, n = 361) and an elderly group (≥ 75years old, n = 165) and compared the clinicopathological factors and prognoses of the two groups. We performed a propensity score-matched (PSM) analysis with inverse probability of treatment weighting (IPTW) to avoid confounding bias. The elderly group had more right-sided tumors and more comorbidities than the young group. After PSM, there were 148 patients in each group. Although the elderly group had significantly shorter overall survival than the young group, the two groups did not differ significantly in cancer-specific survival (CSS; P = 0.136) or recurrence rate (RR; P = 0.317). Multivariate analysis with IPTW also revealed no significant difference in CSS (P = 0.171) or RR (P = 0.284) between the young and elderly groups. Our findings were limited by the study's retrospective single-institute conditions, and the inclusion of only patients who underwent radical resections. Primary tumor resection is appropriate for elderly patients with CRC.

Outcome of Enhanced Recovery After Surgery (ERAS) for Colorectal Surgery in Early Elderly and Late Elderly Patients

This study aimed to determine the outcome of enhanced recovery after surgery (ERAS) programme in elderly colorectal surgery patients. Details and surgical outcomes of elderly patients undergoing elective colectomy and/or proctectomy according to ERAS protocol from 2011 to 2017 were retrospectively reviewed. Patients were divided into 2 groups: early elderly (EE, n = 107) aged 65-74 years old and late elderly (LE, n = 74) aged ≥75 years old. This study included 181 patients. The LE group had poorer baseline characteristics, but the operative details in both groups were comparable. Overall complication and severe complication rates were 28% and 3.3%, respectively. The LE group had a higher overall complication rate (38% vs 22%; P = 0.016) but comparable rate of severe complications (2.7% vs 3.7%; P = 1.00). Median postoperative stay was 4 days (interquartile range [IQR], 4-6 days) and it was not significantly different between both groups (5 days for LE vs 4 days for EE; P = 0.176). No difference was seen in time to gastrointestinal recovery and 30-day mortality or readmission between both groups. Overall compliance with ERAS protocol was 76% (IQR, 65-82%) and it did not vary significantly between the LE (71%) and EE (76%) groups (P = 0.301). However, the LE group had lower compliance with fluid management, nutrition therapy and use of multimodal analgesia. ERAS is a safe and effective protocol that can be used in EE and LE colorectal surgery patients.
