PURPOSE: Femur fractures are among the most common fractures treated surgically, representing a significant challenge for the orthopedic surgeon. Peri-implant femoral fractures (PIFFs) represent a rare complication of the surgical treatment. It is necessary to pay attention during osteosynthesis, evaluating not only the fracture site but the entire femoral skeletal structure, the characteristics of the fracture, the health comorbidities, and the risk of malunion and pseudarthrosis. There are few studies on the incidence, treatment, and outcomes of PIFFs near osteosynthesis. This study aimed to investigate PIFF after osteosynthesis of femoral fractures and evaluate the mortality after surgery and the morbidity associated with these types of fractures. METHODS: A retrospective cohort study was carried out at the IRCCS Galeazzi Orthopedic Institute, Milan, Italy, between January, 2017 and December, 2022. Inclusion criteria were the presence of a femur fracture around an intramedullary nail to treat a previous fracture, follow-up ≥ 12 months, and patients aged ≥ 65 years. Exclusion criterion was intraoperative periprosthetic fractures. The data were expressed as frequency and percentage. Continuous variables were expressed as mean ± standard deviation or median and range. RESULTS: Overall, 25 patients were enrolled (88.0% female) and the mean age was 84.5 years (range of 70 - 92 years). There were 20 patients having type B PIFF and 5 having type C. In 22 patients, multiple comorbidities were found with an average Charlson comorbidity score of 5.5 and the mean time to peri-implant fracture was 38 months. After surgery, 1 patient (4.0%) presented renal failure, 1 (4.0%) needed removal surgery for their loosening, and 2 (8.0%) presented surgical site infection. Nine patients (36.0%) died within 1 year with a mortality rate of 20.0% at 30 days, 8.0% at 3 months, and 8.0% at 12 months. CONCLUSIONS PIFFs in elderly patients are associated with high short-term mortality and morbidity, so careful planning for primary fracture surgery and patient awareness to ensure prolonged compliance and a healthy lifestyle are essential for prevention.

To evaluate the early and mid-term results after surgical repair of thoracoabdominal aortic aneurysm(TAAA)in patients with DeBakey typeⅠor Ⅲ aortic dissection. The clinical data of 130 patients who underwent TAAA repair for chronic DeBakey typeⅠ(groupⅠ, =47)or type Ⅲ(group Ⅲ, =83)aortic dissections in our center between January 2009 and December 2017 were retrospectively analyzed.Early postoperative results,midterm survival,and re-interventions were compared between these two groups. The 30-day mortality rate was 6.9%(=9)in the overall cohort,with no statistic difference between groupⅠand group Ⅲ(10.6% 4.8%;=0.803, =0.370).The incidence of major adverse events(38.3% 51.8%;=2.199, =0.138),5-year actuarial survival rate [(81.7±5.9)% (87.2±4.2)%;=0.483, =0.487],and 5-year actuarial freedom from all reinterventions [(84.5±6.7)% (85.5±4.8)%;=0.010, =0.920] showed no significant differences between these two groups. The early and mid-term outcomes after surgical repair of TAAA are similar for DeBakey typeⅠ and type Ⅲ patients.However,studies with larger sample sizes are still required.

PURPOSE: The purpose of this study was to determine whether poor preoperative nutritional status in elderly patients exhibited a negative influence on postoperative clinical outcomes.METHODS: The medical records of 645 elderly patients were examined retrospectively. The patients had undergone major surgery between January 2017 and January 2018. Their nutritional status was measured using the Nutritional Risk Screening 2002. The data were analyzed using the chi-squared test, the Mann-Whitney U test, logistic regression, linear regression, Cox proportional hazards regression, and the Kaplan-Meier analysis.RESULTS: Preoperative malnutrition was found in 73 patients (11.3%). Poor preoperative nutritional status was significantly associated with pressure ulcers, length of hospitalization, discharge to patient care facilities rather than home, and mortality rate at three months.CONCLUSION: Preoperative malnutrition in elderly patients was associated with negative postoperative clinical outcomes. These results indicate that an effective nutritional program before surgery can lead to a more rapid postoperative recovery.

PURPOSE: The use of endovascular aneurysm repair (EVAR) for ruptured abdominal aortic aneurysms (r-AAA) is steadily increasing. We report early experiences of EVAR for r-AAA performed in two tertiary referral centers in Korea. METHODS: We retrospectively reviewed r-AAA patients treated by EVAR from May 2013 to December 2017. An EVAR-first strategy for r-AAA was adopted whenever feasible. The demographic information, anatomic characteristics, operative details, postoperative complications with special attention to abdominal compartment syndrome (ACS), and 30-day mortality were collected and analyzed. RESULTS: We identified 13 patients who underwent EVAR for r-AAA. Mean age was 74.2 years and mean AAA size was 74.2 mm. Two patients underwent cardiopulmonary resuscitation at initial presentation. Bifurcated stent grafts were used in 12 out of 13 cases and physician-modified endografts with fenestrated/chimney techniques were performed in 2 cases with short neck. Successful stent graft deployment was achieved in all cases. Three patients were suspected of having ACS and 2 of them underwent laparotomy for decompression. The 30-day mortality was 7.7% (1 of 13), the only mortality being a patient that refused decompressive laparotomy for suspected ACS. CONCLUSION: Despite the small numbers, the outcomes of EVAR for treatment of r-AAA were very promising, even in selected cases with unfavorable anatomy. These outcomes were achieved by a dedicated and well-trained team approach, and by use of high-end angiographic technology. Finally, ACS after EVAR is not uncommon, and requires a high index of suspicion as well as liberal use of decompressive surgery.

PURPOSE: To assess the feasibility of transanal total mesorectal excision in difficult cases including obese patients or patients with bulky tumors or threatened mesorectal fascias. METHODS: We performed laparoscopy-assisted transanal total mesorectal excision in patients with biopsy-proven rectal adenocarcinoma located 3–12 cm from the anal verge as part of a prospective, single arm, pilot trial. The primary endpoint was resection quality and circumferential resection margin involvement. Secondary endpoints included the number of harvested lymph nodes and 30-day postoperative complications. RESULTS: A total of 12 patients (9 men and 3 women) were enrolled: one obese patient, 7 with large tumors and 8 with threatened mesorectal fascias (4 patients had multiple indications). Tumors were located a median of 5.5 cm from the anal verge, and all patients received preoperative chemoradiotherapy. Median operating time was 191 minutes, and there were no intraoperative complications. One patient needed conversion to open surgery for ureterocystostomy after en bloc resection. Complete or near-complete excision and negative circumferential resection margins were achieved in all cases. The median number of harvested lymph nodes was 15.5. There was no postoperative mortality and 3 cases of postoperative morbidity (1 postoperative ileus, 1 wound problem near the stoma site, and 1 anastomotic dehiscence). CONCLUSION: This pilot study showed that transanal total mesorectal excision is also feasible in difficult laparoscopic cases such as in obese patients or those with bulky tumors or tumors threatening the mesorectal fascia. Additional larger studies are needed.

PURPOSE: The purpose of this study was to investigate whether the indicators of nutritional risk screening tool are associated with postoperative complications following pancreaticoduodenectomy (PD). METHODS: We investigated whether nutritional risk is associated with postoperative complications based on the medical records of 128 patients who underwent PD from 2010. The tool was composed of 6 risk factors: albumin, total lymphocyte count, body mass index, weight loss, dietary intake loss, and nutritional symptoms. The patients were divided into 2 groups: a nutritional risk group and a nonrisk group. The rates of general complications and postoperative pancreatic fistula (POPF) were investigated according to this nutritional status. RESULTS: There were 65 patients who did not have any risk factors. However, 63 patients had one risk factor or more. In the nonrisk group, the overall complication rate and serious complication rate were 30.8% and 15.4%, respectively. If there were one or more risk factors, the overall and serious complication rates were 59.5% and 41.3%, respectively (P = 0.001 and P = 0.001, respectively). The rate of clinically relevant POPF (grade B or C) was 9.2% in the nonrisk group. However, this rate was 23.8% in the NRS risk group (P = 0.029). In multivariate analysis, the NRS risk group was a significant factor of clinically relevant POPF (odds ratio, 9.878; 95% confidence interval, 1.527–63.914; P = 0.016). CONCLUSION: There were statistically significant associations between complications and nutritional indicators. A comprehensive analysis of nutritional parameters will help predict postoperative complications.

BACKGROUND: Pulmonary thromboembolism (PTE) is a life-threatening disease with high mortality. This study aimed to assess the outcomes of surgical embolectomy and to clarify the sustained long-term effects of surgery by comparing preoperative, postoperative, and long-term follow-up echocardiography outcomes. Of 22 survivors, 21 were followed up for a mean (median) period of 6.8±5.4 years (4.2 years). METHODS: We retrospectively reviewed 27 surgical embolectomy cases for massive or submassive acute PTE from 2003 to 2016. Immediate and long-term follow-up outcomes of surgical embolectomy were assessed on the basis of 30-day mortality, long-term mortality, postoperative complications, right ventricular systolic pressure, and tricuspid regurgitation grade. RESULTS: The 30-day and long-term mortality rates were 14.8% (4 of 27) and 4.3% (1 of 23), respectively. Three patients had major postoperative complications, including hypoxic brain damage, acute kidney injury, and endobronchial bleeding, respectively (3.7% each). Right ventricular systolic pressure (median [range], mm Hg) decreased from 62.0 (45.5–78.5) to 31.0 (25.7–37.0, p<0.001). The tricuspid valve regurgitation grade (median [range]) decreased from 1.5 (0.63–2.00) to 0.50 (0.50–1.00, p<0.05). The improvement lasted until the last echocardiographic follow-up. CONCLUSION: Surgical embolectomy revealed favorable mortality and morbidity rates in patients with acute massive or submassive PTE, with sustained long-term improvements in cardiac function.

BACKGROUND: The endovascular approach to aortic disease treatment has been increasingly utilized in the past 2 decades. This study aimed to determine the long-term results of using the Seal thoracic stent graft. METHODS: We retrospectively reviewed the outcomes of patients who underwent thoracic endovascular aortic repair or a hybrid procedure using the Seal thoracic stent graft (S&G Biotech, Seongnam, Korea) from January 2008 to July 2018 at a single institution. We investigated in-hospital mortality and the incidence of postoperative complications. We also investigated the mid-term survival rate and incidence of aorta-related complications. RESULTS: Among 72 patients with stent grafts, 15 patients underwent the hybrid procedure and 21 underwent emergency surgery. The mean follow-up period was 37.86±30.73 months (range, 0–124 months). Five patients (6.9%) died within 30 days. Two patients developed cerebrovascular accidents. Spinal cord injury occurred in 2 patients. Postoperative renal failure, postoperative extracorporeal membrane oxygenation support, and pneumonia were reported in 3, 1, and 6 patients, respectively. Stent-related aortic complications were observed in 5 patients (6.8%). The 1- and 5-year survival and freedom from stent-induced aortic event rates were 81.5% and 58.7%, and 97.0% and 89.1%, respectively. CONCLUSION: The use of the Seal thoracic stent graft yielded good mid-term results. Further studies are needed to examine the long-term outcomes of this device.

PURPOSE: There are several commercially approved stent grafts in Korea for the treatment of abdominal aortic aneurysms (AAAs). Each device has its advantages and disadvantages based on the patient’s anatomy and the clinical situation. The Zenith device allows accurate and precise endograft placement, whereas the Endurant device has improved flexibility and trackability. We reviewed 5 cases in which a combination of the Zenith main body and the Endurant iliac limb was used. MATERIALS AND METHODS: From January 2010 to February 2015, 90 patients with AAA underwent endovascular aneurysm repair (EVAR) using the Zenith body at Daegu Catholic University Hospital. Among them, 5 patients who underwent EVAR with the Zenith body and Endurant iliac limb were included in this study. RESULTS: The mean age of the patients was 74.20±3.35 years. All patients were men. The main reason for use of the Endurant iliac limb was aortoiliac angulation. Type III endoleak, stent migration, and stent kinking were not noted. Comparing 85 patients who received a Zenith endograft with 5 patients who received the hybrid endograft, there were no statistical differences in clinical characteristics, intraoperative details and post procedural complications. The mean admission duration was 19.00±13.60 days, and the mean follow-up duration was 1,018.11±925.34 days. In the hybrid endograft group, there was no mortality during the follow-up duration. CONCLUSION: Although the material, radial force, diameter, and length of the overlap zone differ between the two devices, EVAR with the hybrid endograft is safe and effective.
