Factors Associated with Urgent Amputation Status and Its Impact on Mortality

ObjectivesThirty-day mortality is higher after urgent major lower extremity amputations compared to elective lower extremity amputations. This study aims to identify factors associated with urgent amputations and to examine their impact on perioperative outcomes and long-term mortality. MethodsPatients undergoing major lower limb amputation from 2013-2020 in the Vascular Quality Initiative (VQI) were included. Urgent amputation was defined as occurring within 72 hours of admission. Associations with sociodemographic characteristics, comorbidities, and outcomes including postoperative complication, inpatient death, and long-term survival were compared using univariable tests and multivariable logistic regression. Long-term survival between groups was compared using Kaplan-Meier analysis. ResultsOf the 12,874 patients included, 4,850 (37.7%) had urgent and 8,024 (62.3%) had elective amputations. Nonwhite patients required urgent amputation more often than white patients (39.8% vs 37.9%, P=0.03). A higher proportion of Medicaid and self-pay patients presented urgently (Medicaid:13.0% vs 11.0%; self-pay: 3.4% vs 2.5%, P< 0.001). Patients requiring urgent amputation were less often taking aspirin (55.6% vs 60.1%, P<0.001) or statin (62.2% vs 67.2%, P<0.001), had fewer prior revascularization procedures (41.0% vs 48.8%, P<0.001), and were of higher ASA class 4-5 (50.9% vs 40.1%, P<0.001). Urgent amputations were more commonly for uncontrolled infection (48.1% vs 29.4%, P< 0.001) or acute limb ischemia (14.3% vs 6.2%, P<0.001). Post-operative complications were higher after urgent amputations (34.7% vs 16.6%, P<0.001), including need for return to operating room (23.8% vs 8.4%, P< 0.001) and need for higher revision (15.2% vs 4.5%, P<0.001). Inpatient mortality was higher after urgent amputation (8.9% vs 5.4%, P<0.001). Multivariable analysis revealed non-white race, self-pay, homelessness, current smoking, ASA class 4-5, and amputations for uncontrolled infection or acute limb ischemia were associated with urgent status, whereas living in a nursing home or prior revascularization were protective. Further, urgent amputation was associated with an increased odds of postoperative complication or death (OR 1.86 [1.69-2.04], P<0.001) as well as long-term mortality (OR: 1.24 [1.13-1.35], P<0.001). Kaplan-Meier analysis corroborated that elective status was associated with improvement of long-term survival. ConclusionsPatients requiring urgent amputations are more often nonwhite, uninsured, and less frequently had prior revascularization procedures, revealing disparities in access to care. Urgency was associated with a higher post-operative complication rate, as well as increased long-term mortality. Efforts should be directed towards reducing these disparities to improve outcomes following amputation.

Urological outcomes following pelvic exenteration for non-urological malignancies

BackgroundPelvic exenteration (PE) is a major surgical procedure used as a salvage therapy for patients with locally advanced or recurrent pelvic malignancies. Urinary reconstruction is a major part of PE and is often associated with high rates of post-operative complications. In the current study we evaluate the short and long-term urological outcomes following PE for Colo-Rectal (CR) and gyneco-oncological (GO) malignancies. MethodsStudy included 22 patients who underwent PE for recurrent or locally advanced CR and GO malignancies in our institution between the years 2010–2018. The endpoint was post-operative freedom from urological complications. ResultsOf 22 patients included, 13 (59 %) and 9 (41 %) underwent PE for CR and GO malignancies respectively. The mean age of the patients was 54 years. The median follow-up was 19 months. Seven (78 %) patients with GO malignancy and 11 (85 %) with CR malignancy underwent PE for local recurrence. Hydronephrosis prior to surgery existed in 8 (36.3 %) patients, of which, 5 patients required kidney drainage via nephrostomy tube. Two patients underwent posterior pelvic exenteration (PPE) with bladder preservation whereas the remaining 20 underwent cystectomy with urinary diversion by ileal conduit. Hydronephrosis post PE developed in 13 patients (59 %). eight (36 %) patients needed kidney drainage by nephrostomy tubes post PE, of these, 6 (75 %) had disease recurrence. The 2 years freedom from kidney drainage was 68 %, however the median time for kidney drainage was 0.5 months. The median overall survival was 12.5 months. ConclusionThe rate of urological complications following PE is relatively high and associated with disease recurrence.

Triplane technique for breast reconstruction after breast cancer surgery: A case series report.

Implant-based breast reconstruction is an important method for post-mastectomy breast reconstruction. Currently, the most commonly used technique is the biplane technique. However, the high rate of postoperative complications, the inability of pockets to accommodate larger implants, and the expensive costs of biological mesh make the development of new surgical methods urgent. The triplane technique for breast reconstruction is an ideal candidate method. The main local symptoms were breast lump, abnormal breast skin, nipple discharge, and abnormal nipple or areola in 24 patients. The study included 24 female patients who underwent breast reconstruction using the triplane technique after radical breast cancer surgery. The surgical procedure involved measuring the dimensions of the breast, designing the incision, and creating a pocket for the implant using the triplane technique, which includes the pectoralis major muscle, the pectoralis major fascia continuing to the rectus abdominis fascia, and the latissimus dorsa muscle fascia continuing to the rectus abdominis fascia. Postoperative follow-up included regular assessments of pain and evaluation of breast appearance. No cases of postoperative infection were observed in all patients. During the 1-year follow-up period after surgery, 5 patients (20.8%) who needed radiotherapy after mastectomy for cancer showed slight darkening of skin flap pigment after using the triplane technique implant. No cases of exposure or infection of the expanders were reported, and 1 patient underwent expander replacement with a permanent prosthesis. All patients expressed satisfaction with the reconstructed breast shape. The 10 patients (41.7%) experiencing postoperative swelling and pain. However, the pain gradually subsided during the postoperative recovery period. No cases of local recurrence or distant metastasis of breast cancer were observed during the 1-year-follow-up period. The triplane technique for breast reconstruction after breast cancer surgery provides good implant coverage, reduces the risk of complications, and is cost-effective.

National clinical and financial outcomes associated with acute kidney injury following esophagectomy for cancer.

Esophagectomy is a complex oncologic operation associated with high rates of postoperative complications. While respiratory and septic complications have been well-defined, the implications of acute kidney injury (AKI) remain unclear. Using a nationally representative database, we aimed to characterize the association of AKI with mortality, resource use, and 30-day readmission. All adults undergoing elective esophagectomy with a diagnosis of esophageal or gastric cancer were identified in the 2010-2019 Nationwide Readmissions Database. Study cohorts were stratified based on presence of AKI. Multivariable regressions and Royston-Parmar survival analysis were used to evaluate the independent association between AKI and outcomes of interest. Of an estimated 40,438 patients, 3,210 (7.9%) developed AKI. Over the 10-year study period, the incidence of AKI increased from 6.4% to 9.7%. Prior radiation/chemotherapy and minimally invasive operations were associated with reduced odds of AKI, whereas public insurance coverage and concurrent infectious and respiratory complications had greater risk of AKI. After risk adjustment, AKI remained independently associated with greater odds of in-hospital mortality (AOR: 4.59, 95% CI: 3.62-5.83) and had significantly increased attributable costs ($112,000 vs $54,000) and length of stay (25.7 vs 13.3 days) compared to patients without AKI. Furthermore, AKI demonstrated significantly increased hazard of 30-day readmission (hazard ratio: 1.16, 95% CI: 1.01-1.32). AKI after esophagectomy is associated with greater risk of mortality, hospitalization costs, and 30-day readmission. Given the significant adverse consequences of AKI, careful perioperative management to mitigate this complication may improve quality of esophageal surgical care at the national level.

The Effect of Hospital-Based Liquid Diet and Commercial Formulas on Laboratory Parameters and Postoperative Complications in Patients with Head and Neck Cancer.

Background: Patients with head and neck cancer (HNC) are at high risk of malnutrition. The aim of this study was to compare the effect of polymeric formulas available commercially and a high-protein liquid diet prepared in the hospital on laboratory parameters and postoperative complications in patients undergoing surgery for HNC. Methods: This single-center retrospective study included 149 patients who underwent surgery for HNC between 2008 and 2017. The following data were collected: patient and tumor characteristics, postoperative complications, and laboratory parameters measured at baseline and after surgery, including creatinine, alanine transaminase (ALT), aspartate transaminase (AST), and blood glucose levels. Correlations between the duration of enteral nutrition and blood parameters were assessed. Results: After surgery, patients receiving commercial formulas had lower creatinine and blood glucose levels and higher ALT and ASP levels than those on the hospital-based diet. The longer duration of feeding with commercial formulas before surgery was associated with enhanced preoperative levels of ALT and ASP and with lower postoperative blood glucose. Patients on the hospital-based diet had a higher rate of postoperative complications than those receiving commercial formulas (16.1% vs. 3.3%). Conclusions: There were no clinically important differences in blood parameters among patients with HNC depending on the type of preparations used for enteral feeding. However, increased levels of liver enzymes in patients fed with commercial formulas were notable. The early initiation of enteral nutrition before surgery helped achieve normal blood glucose levels after surgery. The use of commercial preparations contributed to reducing the number and incidence of postoperative complications.

Comparison of abdominal adipose tissue versus body mass index (BMI) as a predictor of complications and survival in liver transplantation

IntroductionBecause of the obesity epidemic, more obese patients are on liver transplant (LT) waiting lists. The diseases associated with obesity may increase complications and limit survival after LT. However, there is no established measure or cut-off point to determine this impact and aid decision making. The aim of the present study is to evaluate obesity in patients undergoing LT via BMI and CT-based measurement of adipose tissue (AAT). These parameters will be used to predict the risk of postoperative complications and 5-year survival. MethodsA retrospective, single-center study was carried out at a tertiary Spanish hospital, including all patients who received LT between January 2012 and July 2019 (n = 164).The patients were adults who underwent LT using the ‘piggyback’ technique, preserving the recipient vena cava. Visceral adipose tissue (VAT) and BMI were calculated to examine correlations with postoperative complications and 5-year survival. ResultsNo significant association was found between postoperative complications by Comprehensive Complication Index, BMI, AAT/height, subcutaneous fat/height and VAT/height.Kaplan-Meier curves for 5-year survival compared LT recipients with BMI < 30.45 versus ≥30.45, with an estimated survival of 58.97 months versus 43.11 months, respectively (P < .001) (Fig. 3) and for LT recipients with an AAT/height <27.35 mm versus ≥27.35 mm, with an estimated survival of 57.69 months versus 46.34 months (P = .001). ConclusionsThis study does not show a higher rate of postoperative complications in obese patients. There is a significantly lower long-term survival in patients with AAT/height ≥27.35 mm and BMI ≥ 30.45. BMI is a valid estimate of obesity and is predictive of survival.

Impact of sarcopenia on the short-term and long-term outcomes of intrahepatic cholangiocarcinoma undergoing hepatectomy: A multi-center study

BackgroundSarcopenia is associated with adverse prognosis of intrahepatic cholangiocarcinoma (iCCA) after surgery. Methods321 patients with iCCA undergoing surgery were retrospectively recruited and assigned to training and validation cohort. Skeletal muscle index (SMI) was assessed to define sarcopenia. Logistic regression and cox regression analysis were used to identify risk factors. A novel sarcopenia-based nomogram was constructed and validated by ROC curves, calibration curves, and DCA curves. Results260 patients were included for analysis. The median age was 63.0 years and 161 patients (61.9%) were diagnosed with sarcopenia. Patients with sarcopenia exhibited a higher rate of postoperative complications, a worse OS and RFS than patients without sarcopenia. Sarcopenia, low albumin and intraoperative blood transfusion were independent risk factors of postoperative complications, while sarcopenia and low albumin were risk factors of high CCI≥26.2. Sarcopenia, high PS score, low-undifferentiated differentiation, perineural invasion, TNM stage III-IV were risk factors of OS, and a novel nomogram based on these five factors was built to predict the 12-, 24-, and 36-months OS, with the mean AUC > 0.6. ConclusionSarcopenia is negatively associated with both postoperative complications and survival prognosis of iCCA undergoing hepatectomy.

Comparison of the transarterial, transvenous, and superior ophthalmic vein approaches in the treatment of indirect carotid-cavernous fistulas.

Indirect carotid-cavernous fistulas (CCFs) are abnormal arteriovenous shunting lesions with a highly variable clinical presentation that depends on the drainage pattern. Based on venous drainage, treatment can be either transarterial (TA) or transvenous (TV). The aim of this study was to compare the outcomes of indirect CCF embolization via the TA, TV, and direct superior ophthalmic vein (SOV) approaches. The authors conducted a retrospective analysis of 74 patients admitted to their institution from 2010 to 2023 with the diagnosis of 77 indirect CCFs as confirmed on digital subtraction angiography. A total of 74 patients with 77 indirect CCFs were included in this study. Embolization was performed via the TA approach in 4 cases, the TV approach in 50 cases, and the SOV in 23 cases. At the end of the procedure, complete occlusion was achieved in 76 (98.7%) cases. The rate of complete occlusion at the end of the procedure and at last radiological follow-up was significantly higher in the SOV and TV cohorts than in the TA cohort. The rate of recurrence was highest in the TA cohort (25% for TA vs 5.3% for TV vs 0% for SOV, p = 0.68). The rate of immediate complete occlusion was higher in the TV and SOV cohorts than in the TA cohort while the rate of complete occlusion at final follow-up was highest in the SOV cohort. The SOV approach was significantly associated with higher rates of postoperative complications. Indirect CCFs require careful examination of the fistulous point and the venous drainage to provide the most effective patient-tailored approach.

The intersection of pediatric anesthesiology and social determinants of health.

There is increasing evidence of racial and ethnic disparities in pediatric perioperative care, which indicates a need to identify factors driving disparities. Social determinants of health (SDOH) play a fundamental role in pediatric health and are recognized as key underlying mechanisms of healthcare inequities. This article summarizes recent research exploring the influence of SDOH on pediatric perioperative outcomes. Despite the scarcity of research exploring SDOH and pediatric perioperative outcomes, recent work demonstrates an association between SDOH and multiple outcomes across the perioperative care continuum. Measures of social disadvantage were associated with preoperative symptom severity, longer hospital stays, and higher rates of postoperative complications and mortality. In some studies, these adverse effects of social disadvantage persisted even when controlling for medical comorbidities and clinical severity. The existing literature offers compelling evidence of the impact of SDOH on perioperative outcomes in children and reveals a critical area in pediatric anesthesia that necessitates further exploration and action. To improve outcomes and address care inequities, future efforts should prioritize the integration of SDOH assessment into pediatric perioperative research and practice.

Refining Bacteriuria as a Risk Factor for Complications After Urethroplasty: Identifying the Culprit

To determine which bacteria are associated with an increased risk of 90-day complications after urethroplasty. Preoperative bacteriuria is associated with an increased risk of complications after urethroplasty. However, it remains unclear which specific micro-organisms are the primary drivers of this morbidity. A single-institution, 2-surgeon retrospective review was performed on patients undergoing urethroplasty from 08/2003 to 06/2021. Preoperative bacteriuria was considered significant when the patient had a mixed culture with ≥108 CFU/L or an identifiable micro-organism with ≥106 CFU/L. Descriptive statistics were used to summarize the results and chi-square was used to determine the association between 90-day complications (Clavien ≥2) and clinical characteristics/bacteria. Out of 1611 patients, 23.2% (373) had significant preoperative bacteriuria. The most common pathogens included coagulase-negative staphylococcus 18.5% (69), mixed growth 15.8% (59), Escherichia coli 10.7% (40), and Enterococcus 14.2% (53). 7.9% (128/1611) experienced a significant 90-day complication (Clavien-Dindo ≥2). Gram-negative bacilli including E coli, Pseudomonas sp, Klebsiella sp, Serratia sp, Citrobacter sp, Achromobacter sp, Stenotrophomonas sp, and Morganella sp were associated with higher rates of postoperative complications (14.2%; P=.01) as well as Enterococcus sp (15.1%; P=.03). However, gram-positive cocci (7.9%; P=.97), gram-positive bacilli (11.8%; P=.47), mixed growth (5.1%; P=.54) and Candida (16.7%; P=.27) were not. Neither escalating concentrations of bacteria (P=.44) or number of strains (P=.08) were associated with increased risk of complications. The main driver of bacteriuria-related complications after urethroplasty are gram-negative bacilli and Enterococcus sp. Patients with bacteriuria related to other micro-organisms can likely proceed with urethroplasty without increased risk of postoperative complications.

P433 Short-term outcomes of surgical treatment in primary ileocecal Crohn’s disease patients. Results of Crohn’s(urg) study, multicenter, retrospective, comparative analysis between indications for luminal and complicated phenotype

Abstract Background Recent evidence challenges the current standard of offering surgery to patients with ileocecal Crohn’s disease only when they present complications of the disease. Methods A retrospective, multicenter comparative analysis was performed including patients operated for primary ileocecal CD at 12 referral centers. Patients were divided in 2 groups, according to indication of surgery for inflammatory (ICD) or complicated (CCD) phenotype. Short-term results were compared. Patients operated on for primary isolated ileocaecal CD (last 50 cm of the terminal ileum and cecum), either for predominantly inflammatory phenotype or for complications of the disease (stricturing or fistulizing pattern), between January 2012 - December 2021 were considered eligible to participate in this study. Patients with previous abdominal procedures for CD, and patients who had activity of the disease in other intestinal segments other than the ileocaecal region at the time of surgery, were excluded from the study. Results 2013 patients were included, 291 (14.5%) in the ICD group. No differences were found between groups in time from diagnosis to surgery or in the levels of exposure to biologic drugs before indication of surgery. CCD patients had higher rates of low BMI, anemia (40.9 vs. 27%, p: &amp;lt; 0.001), and low albumin (11.3 vs. 2.6%, p: &amp;lt; 0.001). CCD patients had longer operations, lower rates of laparoscopic approach (84.3 vs. 93.1%, p: 0.001), and higher conversion rates (9.3 vs. 1.9%, p: &amp;lt; 0.001). CCD had longer hospital stay and higher postoperative complication rates (26.1 vs. 21.3%, p: 0.083). Anastomotic leakage and reoperations were also more frequent in this group. More patients in the CCD group required an extended bowel resection (14.1 vs. 8.3%, p: 0.017). In multivariate analysis, CCD was associated with prolonged surgeries (OR: 3.44, p: 0.001) and requirements of multiple intraoperative procedures (OR: 8.39, p: 0.030). Conclusion Indication of surgery in patients who present an inflammatory phenotype of CD was associated with better outcomes when compared to patients operated on for complications of the disease, without a difference between groups in time from diagnosis to surgery.

Outcomes of elderly patients with node-positive colon cancer: A multi-center population-based cohort study.

33 Background: Patients with stage III colon cancer are at high risk of recurrent disease. In this large population based cohort study we examined prognostic significance of chemotherapy and other clinical, pathological &amp; contextual variables that are associated with inferior outcomes in elderly patients with stage III colon cancer. Methods: Patients ≥ 70 years with stage III colon cancer diagnosed in Saskatchewan, a Canadian province, and underwent resection of the primary tumor during 2012-2018 were evaluated. A Cox proportional multivariate survival analysis was performed to determine factors correlated with overall survival (OS) and disease-free survival (DFS). Results: 404 eligible patients with median age of 79 yrs &amp; M:F of 1:1 were identified. 48% were ≥80 years, 60% were rural resident, 66% had ≥ 1 major comorbid illness, 34% had WHO performance status &gt;1, 14% has an ostomy formation, 46% had a T4 or N2 high-risk disease, and 50% had node positive to node harvested (NPNH) ratio of &gt;0.1. 43% patients received adjuvant chemotherapy. Median time to start chemo was 9 weeks. Patients who did not receive adjuvant chemotherapy were significantly older, had low performance status or experienced high rate of post-operative complications, high serum creatinine, low albumin, anemia, elevated WBC count and platelets. Median OS of all patients was 51 months (95%CI: 42.4-59.6), with estimated 5 &amp; 10-yr OS of 45% and 30%. Median DFS of entire cohort was 32 months (26.3-37.7) with 5 &amp; 10-yr DFS of 34% and 20%. Patients who received adjuvant chemotherapy had median OS of 106 months (83.8-128.5) vs. 30 months (23.4-36.6), p&lt;0.001 with 5 &amp; 10-yr OS of 64% and 49% vs. 31% and 19% (p&lt;0.001). Patients who received adjuvant chemotherapy had median DFS of 56 months (28.2-83.9) vs. 22 months (16.5-27.5), p&lt;0.001 with 5 &amp; 10-yr DFS of was 49% and 30% vs. 24% and 13% (p=&lt;0.001). The Cox-multivariate analysis revealed a past history of cancer, HR, 1.32 (1.03-1.72); ostomy, HR, 1.33 (1.02-1.74); NPNH ratio &gt;0.1, 1.34 (1.04-1.78); grade III tumor, 1.36 (1.04-1.78); WHO performance status &gt;1, HR, 1.38 (1.05-1.82); no adjuvant chemo, HR, 1.38 (1.03-1.85); high-risk stage III disease, HR, 1.39 (1.10-1.79), and baseline CEA &gt;5, HR, 1.75 (1.34-2.29), were independently correlated with DFS whereas past history of cancer, HR, 1.47 (1.12-1.94); ostomy, HR, 1.53 (1.16-2.03); NPNH ratio &gt;0.1, 1.51 (1.15-1.98); grade III tumor, 1.54 (1.16-2.04); WHO performance status &gt;1, HR, 1.42 (1.06-1.90); no adjuvant chemo, HR, 1.82 (1.32-2.50); high-risk stage III disease, HR, 1.60 (1.22-2.11), and CEA &gt;5, HR, 1.98 (1.50-2.61) were independently correlated with OS. Conclusions: In elderly patients with stage III colon cancer lack of adjuvant chemotherapy, poor performance status, T4 or N2 disease, grade III tumor, elevated baseline CEA, past history of a secondary cancer, elevate NPNH ratio &gt;0.1 and an ostomy formation correlate with inferior outcomes.

What is the Ideal Surgical Approach for Perforated Gastro-Duodenal Ulcer?

This is a single-center, non-randomized retrospective study that compares various clinical and evolutionary aspects of patients with perforated gastro-duodenal ulcers in order to determine the best surgical approach. The study included 35 patients who underwent surgical treatment for a perforated gastro-duodenal ulcer at Brașov County Emergency Clinical Hospital (SCJU BV) between January 2021 and January 2023. They were then divided into two groups based on whether the surgery was laparoscopic or traditional. A variety of clinical and paraclinical data were collected and compared. There were no variations in gender distribution, age, or site of the ulcer perforation across the groups. Patients who underwent a laparoscopic procedure had a smaller ulcer perforation, a faster resumption of intestinal transit, and a shorter hospital stay than those who underwent a standard procedure. At 3 days postoperatively, the Neutrophil-to-Lymphocyte Ratio (NLR) and the Systemic Inflammation Response Index (SIRI) were significantly lower in the laparoscopic group. Patients who underwent traditional surgery had a higher Boey score, needed more complex interventions, and had a higher rate of postoperative complications and mortality. In perforated gastro-duodenal ulcer cases, the laparoscopic approach is a viable option with numerous advantages, particularly in patients with a low Boey score. Meanwhile, the traditional approach may be reserved for cases with a high Boey score and complex surgical interventions.

Incidents of Complications after Reconstruction of Neglected Achilles Tendon Injury by Baker's Procedure

Introduction: Neglected Achilles tendon ruptures present a significant challenge in orthopedic surgery, with varied outcomes and complications. This study aims to evaluate the effectiveness of Baker's Procedure in the reconstruction of neglected Achilles tendon ruptures and to analyze the associated postoperative outcomes and complications. Methods: This prospective interventional study was conducted from January 1, 2012, to May 31, 2013, at multiple centers in Dhaka, Bangladesh. It included 42 patients aged 18 to 60 years with neglected Tendo-Achilles ruptures, defined as injuries untreated for over 4 weeks. Baker's Procedure, involving gastrocnemius aponeurosis advancement, was employed for reconstruction. Result: Of the 42 participants, 71.43% were male, with a mean age of 30.7 years. Injuries predominantly occurred in the right Achilles tendon (57.14%) and were mainly caused by sharp-metal objects (57.14%) and toilet-pan accidents (35.71%). Postoperative complications included stitch or wound infections (21.43%), pain (14.29%), stiffness (28.57%), and calf-muscle weakness (35.71%). Excellent, good, and fair outcomes were achieved in 64.29%, 21.43%, and 14.29% of patients, respectively. Conclusion: Baker’s Procedure is effective in reconstructing neglected Achilles tendon ruptures, with a majority of patients achieving excellent or good outcomes. However, the relatively high rate of postoperative complications, particularly infections, calf muscle weakness and stiffness, highlights the need for improved surgical and postoperative strategies. These findings underscore the importance of tailored.

Evaluation of Factors That Contribute to Intraoperative and Postoperative Complications Following Colorectal Cancer Surgeries at King Abdulaziz University Hospital, Jeddah, Saudi Arabia.

Colorectal cancer (CRC) is a major contributor to cancer-related mortality and morbidity due to its high prevalence. Surgery remains the curative option. Colorectal cancer patients come to our institute at an advanced stage due to the lack of adequate national screening programs in developing countries. This carries a particularly high risk of morbidity and mortality. In this study, we aim to provide an overview of the complications of colorectal cancer surgery and to describe the preoperative and intraoperative factors associated with it. This retrospective record review was done at King Abdulaziz University Hospital (KAUH), a tertiary center in Jeddah, Saudi Arabia. It included all patients aged 18 and older who have undergone colorectal cancer surgeries from January 2017 until August 2022. In our sample of 195 patients, 52.3% of the patients were males. The mean age of our sample was 59.32 ± 13.21. We found that 19 (9.7%) patients had an intraoperative complication (IOC). The most frequent IOC was bleeding reported in seven patients (3.6%), followed by intestinal injury in three (1.2%), bladder injury in three (1.2%), and ureter injury in three (1.2%). Regarding preoperative lab tests, patients who had low blood albumin levels (P = 0.004) and high preoperative white blood cell count (WBC; P = 0.015) were more likely to experience IOC. There was a statistically significant relationship between the patient's ASA score and IOC (P = 0.011).Postoperative complications (POC) occurred in 58 patients (29.7%). The most frequent POC was surgical site infection (SSI; 16.4%), followed by urinary tract infections (UTI) (6.7%) and prolonged postoperative ileus (5.6%). Patients who initially presented with vomiting (P = 0.015), had free air on a preoperative abdominal computed tomography (CT) scan (P = 0.028), required intraoperative blood transfusions (P = 0.033), were diagnosed with transverse colon tumors (P = 0.045), and required longer hospital stays (P = 0.011) were found to have a higher rate of POC. The incidence of colorectal cancer is increasing, and surgery is a successful treatment option. However, complications from surgery may result in morbidities and prolonged hospital stays. The risk of IOC is increased by preoperative variables such as high WBC levels, low albumin, and ASA scores. Patients with initial obstruction signs, free air on CT scans, intraoperative blood transfusions, transverse colon tumors, and longer hospital stays have a higher rate of POC. Patient monitoring and the provision of standardized clinical tools enhance general survival and quality of life.

Association between preoperative frailty and surgical Apgar score in abdominal cancer surgery: a secondary analysis of a prospective observational study

IntroductionThe surgical Apgar score is useful for predicting postoperative morbidity and mortality. However, its applicability in frail patients with minimal hemodynamic variation remains unknown. This study aimed to investigate the association between frailty and surgical Apgar score.MethodsThis secondary analysis included 210 patients ≥ 65 years of age undergoing elective major abdominal surgery for cancer. Frailty was assessed using the Fried Frailty Phenotype Questionnaire and defined as a total score of ≥ 3. The surgical Apgar score (range, 0−10; including mean blood pressure, heart rate, and blood loss volume) was compared between patients with or without frailty using the Mann–Whitney U test. Postoperative severe complications and length of postoperative stay were compared between patients with surgical Apgar scores ≤ 7 and > 7.ResultsAmong the included patients, 45 were classified as frail. The median [1st quartile, 3rd quartile] surgical Apgar scores in patients with and without frailty were 7.0 [7.0, 8.0] and 8.0 [7.0, 8.0], respectively (P = 0.03). Patients with surgical Apgar score ≤7 had a higher incidence of serious postoperative complications (P = 0.03) and longer hospital stays (P < 0.001) compared with patients with surgical Apgar score >7.ConclusionFrail patients have lower SAS, and patients with lower SAS have higher postoperative complication rates and longer hospital stays in patients who underwent cancer surgery.

Transhiatal bilateral cervical approach for mediastinoscopy-assisted esophagectomy: A retrospective cohort study.

The McKeown minimally invasive esophagectomy (McMIE) procedure has various limitations, including surgical contraindications and a high rate of postoperative pulmonary complications. A novel mediastinoscopic esophagectomy procedure was described in this study by using esophageal invagination and a transhiatal and bilateral cervical approach (EITHBC). According to the mode of operation, a total of 259 patients were divided into two groups, among which 106 underwent EITHBC and 153 underwent McMIE. The number of lymph nodes dissected, intraoperative outcomes, and postoperative outcomes were compared between the two groups of patients. The results revealed that the average number of resected lymph node in the EITHBC group was significantly higher in the recL106 and TbL106 stations (recL106: 1.75 vs. 1.51, p=0.016, TbL106: 1.53 vs. 1.19, p=0.016) and significantly lower in the 107 stations (1. 74 vs. 2. 07, p < 0.001) than in the McMIE group. The intraoperative blood loss in the EITHBC group was significantly lower than that in the McMIE group (63.30 vs. 80.45mL, p<0.001). The incidence of postoperative pulmonary complications in the EITHBC group was lower than that in the McMIE group (14.15% vs. 27.45%, p=0.008). The incidence of recurrent laryngeal nerve paralysis in the EITHBC group was significantly higher than that in the McMIE group (26.41% vs. 10.46%, p=0.003). Compared with the McMIE procedure, the EITHBC procedure has advantages in terms of removing the upper mediastinal lymph nodes and reducing postoperative pulmonary complications.

Predictive factors of surgical complications after pelvic exenteration for gynecological malignancies: a large single-institution experience.

To evaluate pre-operative predictors of early (<30 days) severe complications (grade Dindo 3+) in patients with gynecological malignancy submitted to pelvic exenteration (PE). We retrospectively analyzed 129 patients submitted to surgery at Fondazione Policlinico Gemelli between 2010 and 2019. We included patients affected by primary or recurrent/persistent cervical, endometrial, or vulvar/vaginal cancers. Post-operative complications were graded according to the Dindo classification. Logistic regression was used to analyze potential predictors of complications. We performed 63 anterior PE, 10 posterior PE, and 56 total PE. The incidence of early severe post-operative complications was 27.9% (n=36), and the early mortality rate was 2.3% (n=3). More frequent complications were related to the urinary diversion and intestinal surgery. In univariable analysis, hemoglobin ≤10 g/dL (odds ratio [OR]=4.2; 95% confidence interval [CI]=1.65-10.7; p=0.003), low albumin levels (OR=3.9; 95% CI=1.27-12.11; p=0.025), diabetes (OR=4.15; 95% CI=1.22-14.1; p=0.022), 2+ comorbidities at presentation (OR=5.18; 95% CI=1.49-17.93; p=0.012) were predictors of early severe complications. In multivariable analysis, only low hemoglobin and comorbidities at presentation were independent predictors of complications. Pelvic exenteration is an aggressive surgery characterized by a high rate of post-operative complications. Pre-operative assessment of comorbidities and patient health status are crucial to better select the right candidate for this type of surgery.

Efficiency of the estimation of physiologic ability and surgical stress (E-PASS) score in predicting postoperative complications after robot-assisted radical prostatectomy.

Robot-Assisted Radical Prostatectomy (RARP) is increasingly becoming the standard surgical treatment for prostate cancer. While some risk factors for postoperative complications of RARP have been identified, no scoring model that incorporates both preoperative physical status of the patient and intraoperative risk factors has been developed. The Estimation of Physiologic Ability and Surgical Stress (E-PASS) score was initially described to predict postoperative complications after gastrointestinal surgical procedures. This study aims to assess the effectiveness of the E-PASS score in predicting postoperative complications of RARP. A retrospective evaluation was conducted on 204 patients who underwent RARP between 2019 and 2022. Demographic data, parameters indicating patients' preoperative physical condition, and intraoperative risk factors were analyzed. The E-PASS score and subscores were calculated for each patient. Of the patients, 164 (80.4%) were discharged without any postoperative complications (Group 1), and 40 (19.6%) experienced various degrees of complications (Group 2). Patients in Group 2 had higher rates of previous abdominal surgery, elevated Eastern Cooperative Oncology Group (ECOG) performance scores, longer surgical durations, and higher E-PASS scores. To assess the effectiveness of the Comprehensive Risk Score (CRS) as a predictive factor for postoperative complications, a receiver operating characteristic (ROC) curve was constructed with a 95% confidence interval (CI), and a cut-off value was established. The cut-off value for CRS was determined to be -0.0345 (area under the curve [AUC]=0.783, CI: 0.713-0.853; p<0.001). Patients with a CRS higher than the cut-off value had a 16.4 times higher rate of postoperative complications after RARP (95% CI: 5.58-48.5). The E-PASS scoring model successfully predicts postoperative complications in patients undergoing RARP by using preoperative data about the physical status of the patient and surgical risk factors. The E-PASS score and its subscores could be utilized as objective criteria to determine the risk of postoperative complications before and immediately after surgery.

Surgical treatment of feline intracranial meningiomas: a retrospective study of 26 cases.

Surgical excision is the treatment of choice for feline intracranial meningioma. To report clinical findings, complications, and outcomes following surgery for feline intracranial meningioma. Medical records (01/2000-01/2017) of cats that underwent surgical excision of an intracranial meningioma at our institution were reviewed. Patient data included signalment, clinical signs, surgical technique, complications, histopathologic diagnosis, survival time, and owners' answers to a satisfaction questionnaire. Survival was assessed using the Kaplan-Meier method and log-rank test. Twenty-six cats were included in this study. The exact cause of death was known in 17 cases and was not related to meningioma in 9/17 cases. Overall median survival time was 881 days (95% confidence interval 518; 1248). The age of the cat did not influence survival (p = 0.94) or the occurrence of complications (p = 0.051). Complications occurred in 13/24 cats, including dramatic complications in 4/24 cats. Most complications appeared in the first 24 hours post-surgery (12/13). Males had more postoperative complications (p = 0.042), including more seizures (p = 0.016). Cats with cranioplasty had fewer complications (p = 0.021). Clinical recurrence was confirmed in 3 out of 17 cats. Recurrence-free survival time was 826 days. Most owners (12/14) were satisfied with the outcome. Surgical treatment of intracranial meningioma in cats was associated with a long median survival time but also with a high rate of minor and major postoperative complications, including early postoperative seizures. Cranioplasty may reduce complications. Age at the time of surgery had no effect on outcomes.
