Association between recovery from desaturation after stair climbing and postoperative complications in lung resection.

OBJECTIVE: The stair-climbing test (SCT) is used as a surrogate for cardiopulmonary exercise testing, which measures maximal oxygen uptake, and considered a useful method for assessing exercise capacity in thoracic surgery. This study aims to investigate whether the recovery time of percutaneous oxygen saturation (SpO2) after stair climbing is a predictor of postoperative complications after lobectomy. METHODS: We retrospectively identified 54 patients who performed SCT and underwent lobectomy between January 2015 and February 2023 at Shizuoka Cancer Center. The SpO2 recovery time was defined as the time required to recover from the minimum to resting value after stair climbing. The association between SpO2 recovery time and early postoperative pulmonary complications within 30 days after surgery was analyzed. RESULTS: Eleven patients (20.4%) had postoperative pulmonary complications (≥ Clavien-Dindo Classification Grade 2). The cutoff value of SpO2 recovery time obtained from the receiver operating characteristic curve analysis was 90 s [sensitivity, 81.8%; specificity, 72.1%; AUC, 0.77 (95% confidence interval, 0.64-0.90)]. The occurrence of postoperative pulmonary complications was 42.9% in the delayed recovery time (DRT; SpO2 recovery time ≥ 90 s) group and 6.1% in the non-DRT (SpO2 recovery time < 90 s) group (p = 0.002). DRT was a predictor of postoperative pulmonary complications (odds ratio, 11.60; 95% CI 2.19-61.80). CONCLUSIONS: DRT of SpO2 after stair climbing is a predictor of postoperative pulmonary complications following lobectomy in borderline patients who require exercise capacity assessment. SpO2 monitoring after stair climbing may be useful as one of the preoperative assessments in patients undergoing lobectomy.

Postoperative Adverse Events Following Neoadjuvant Therapy and Surgery for Borderline Resectable Pancreatic Cancer in a Phase 2 Clinical Trial (Alliance A021501).

BACKGROUND: Postoperative adverse events (AEs) in patients with borderline resectable pancreatic ductal adenocarcinoma (BR-PC) treated with neoadjuvant therapy and pancreatectomy in the national cooperative group setting have not been previously characterized. We conducted a preplanned secondary analysis of patients enrolled on the Alliance A021501 clinical trial to quantify perioperative AE rates. METHODS: The A021501 phase 2 trial randomized patients with BR-PC to receive 8 doses of mFOLFIRINOX (Arm 1) or 7 doses of mFOLFIRINOX and hypofractionated radiotherapy (Arm 2), followed by pancreatectomy (December 31, 2016 to May 31, 2019). Adverse events were assessed 90 days after pancreatectomy. RESULTS: Of 126 enrolled patients, 51 (40%) underwent pancreatectomy (n = 32, Arm 1; n = 19, Arm 2) at 28 institutions. Five (10%) patients required reoperation within 90 days; 56% of patients (n = 27/48) experienced at least one grade 3 or higher AE (50% vs. 67%, p = 0.37). Ninety-day mortality was 2.0%. Readmission was less frequent in Arm 1 (16% vs. 42%, p = 0.05), but there were no differences between study arms in rates of reoperation (13% vs. 5%), pancreatic fistula or intra-abdominal abscess requiring drainage (9% vs. 16%), or wound infection (6% vs. 16%). Pancreatic fistula or intra-abdominal abscess requiring drainage was associated with receipt of adjuvant therapy (p = 0.012). No difference in overall survival was observed based on occurrence of postoperative AEs (hazard ratio = 1.1; 95% confidence interval 0.5-2.6). CONCLUSIONS: In this multicenter study, rates of postoperative AEs were consistent with those previously reported. Multimodality trials of preoperative therapy for BR-PC may be performed in the cooperative group setting with careful quality assurance and safety monitoring.

Short- and Long-Term Advantages of Laparoscopic Gastrectomy for Elderly Patients with Locally Advanced Cancer.

Minimally invasive surgery has provided several clinical advantages in locally advanced gastric cancer (LAGC) care, although a consensus on its application criteria remains unclear. Surgery remains a careful choice in elderly patients, who frequently present with frailty, comorbidities, and other disabling diseases. This study aims to assess the possible advantages of laparoscopic gastric resections in elderly patients presenting with LAGC. This retrospective study analyzed a single-center series of elderly patients (≥75 years) undergoing curative resections for LAGC between 2015 and 2020. A comparative analysis of open versus laparoscopic approaches was conducted, focusing on postoperative complications, length of hospital stay (LOS), and long-term survival. A total of 62 patients underwent gastrectomy through an open or a laparoscopic approach (31 pts each). The study population did not show statistically significant differences in demographics, operative risk, and neoadjuvant chemotherapy. The laparoscopic group reported significantly minimized overall complications (45.2 vs. 71%, p = 0.039) and pulmonary complications (0 vs. 9.7%, p = 0.038) as well as a shorter LOS (8 vs. 12 days, p = 0.007). Lymph node harvest was equal between the groups, although long-term overall survival presented significantly better after laparoscopic gastrectomy (p = 0.048), without a relevant difference in terms of disease-free and disease-specific survivals. Laparoscopic gastrectomy proves effective in elderly LAGC patients, offering substantial short- and long-term postoperative benefits.

Safety and Effectiveness of Bone Allografts for Mastoid Obliteration After Mastoidectomy: A Pilot Study.

Background and Objectives: : Various materials are used to perform post-mastoidectomy mastoid obliteration (MO) to reduce the risk of recurrent infections, stasis of secretions, or caloric dizziness. Autologous materials used as fillers for MO tend to be insufficient owing to shrinkage over time or inadequate volume of these substances. Synthetic materials are unsatisfactory for MO because of the risk of rejection and extrusion. We investigated the safety and effectiveness of bone allografts for post-mastoidectomy MO. Subjects and Methods: : We reviewed the medical records of patients who underwent mastoidectomy with MO between January 2013 and January 2021. In the MO group, bone allografts were additionally used to fill the residual mastoid cavity. In the canal wall down (CWD) group, all patients underwent CWD mastoidectomy with use of additional inferiorly based mucoperiosteal flaps. Results: : The study included the MO group (23 ears) and the CWD group (53 ears). In the MO group, compared with the preoperative status, we observed a decrease in the tendency of the air-bone gap postoperatively. Compared with the CWD group, the total complication rate showed a decreasing tendency in the MO group. Conclusions: : No patient showed post-MO shrinkage of the grafted bone allograft or otorrhea. Further large-scale studies are warranted to confirm the advantages of bone allografts for MO, including maintenance with time and sufficient amount.

[Robotic Colorectal Surgery: Analysis of the First Three Years of Activity in a Hospital of the Portuguese National Health Service]. / Cirurgia Robótica em Patologia Colorretal: Análise dos Primeiros Três Anos de Atividade num Hospital do Serviço Nacional de Saúde em Portugal.

INTRODUCTION: Minimally invasive surgery has been increasingly accepted and used in colorectal surgery. Several studies report that robotic surgery may provide advantages over 'conventional' laparoscopy, namely in rectal surgery. This paper provides an account of the first three years of experience with robotic surgery in the Unidade de Patologia Colorretal of the Unidade Local de Saúde S. José. METHODS: Variables were defined to develop a prospective database containing the data of consecutive patients operated by three internationally certified colorectal surgeons using the Da Vinci Xi® system between November 2019 and October 2022. The database was converted into an anonymized version that was used for this study. The analysis was performed on the data of all the patients operated during this period. RESULTS: Eighty patients were included, 47 male, median age 70 years, and median BMI 26 kg/m2 . ASA score was II in 53.7% and III in 41.3% of pa- tients. Of the total, 97.6% had malignant or potentially malignant disease. Operative procedures consisted of 34 colectomies proximal to the splenic flexure, 20 distal colectomies and 26 anterior resections. There were two synchronous resections of liver metastases. Early perioperative outcomes and histopathological results were analyzed: median operative time: 300 minutes; median estimated blood loss: 50 mL; conversion rate: 2.5%; median days until first bowel movement: three days; median length of hospital stay: six days; complication rate: 20%, of which 5% were Clavien III and 0% Clavien IV/V; anastomotic leak rate: 2.5%; 30-day readmission rate: 1.3%; median lymph nodes resected: 20; R0 resection rate: 100%; mesorectal integrity rate: 95,8% complete/near complete. CONCLUSION: Our results show that the adoption of robotic colorectal surgery in our center was safe and resulted in similar or improved short-term clinical outcomes and histopathological results when compared to those described in the literature.

Introdução: A utilização da cirurgia minimamente invasiva no tratamento da patologia colorretal é hoje cientificamente aceite e o seu uso na prática clí- nica diária tem vindo a aumentar de forma sustentada. Diversos estudos indicam que a abordagem robótica pode trazer vantagens sobre a laparoscopia 'convencional', especialmente na cirurgia do reto. Este trabalho descreve e analisa os resultados dos primeiros três anos de cirurgia robótica na Unidade de Patologia Colorretal da Unidade Local de Saúde S. José. Métodos: Foram definidas as variáveis a analisar e construída uma base de dados prospetiva com os dados referentes aos doentes operados conse- cutivamente por três cirurgiões colorretais, acreditados internacionalmente na utilização do sistema Da Vinci Xi®, entre novembro de 2019 e outubro de 2022. A base de dados foi convertida numa versão anonimizada e foi sobre essa mesma que se procedeu à análise de dados. Foram analisados os dados de todos doentes operados nesse período. Resultados: Foram incluídos 80 doentes, 47 homens, mediana de idade de 70 anos e de IMC de 26 kg/m2 . O score ASA era II em 53,7% e III em 41,3% dos doentes. Do total, 97,6% apresentavam doença maligna ou potencialmente maligna. Realizaram-se 34 colectomias proximais ao ângulo esplénico, 20 distais e 26 ressecções anteriores do reto. Houve ressecção síncrona de metástases hepáticas em dois casos. Foram analisados os resultados peri-operatórios a curto prazo e histopatológicos: duração (mediana): 300 minutos; perda hemática estimada (mediana): 50 mL; taxa de conversão: 2,5%; dias até retomar trânsito intestinal (mediana): três dias; dias de internamento (mediana): seis dias; taxa de complicações pós-operatórias: 20%, das quais 5% Clavien III e 0% Clavien IV/V; taxa de deiscência anastomótica: 2,5%; taxa de reintervenção: 2,5%; taxa de readmissão pós-alta: 1,3%; gânglios linfáticos ressecados (mediana): 20; taxa de ressecção R0: 100%; taxa de integridade mesorretal: 95,8% completo/quase completo. Conclusão: Os nossos resultados mostram que a introdução da cirurgia colorretal robótica no nosso centro foi segura e garantiu resultados clínicos a curto prazo e histopatológicos semelhantes ou favoráveis face aos descritos na literatura.

Human umbilical cord allograft associated with higher pediatric urethrocutaneous fistula repair success rates.

BACKGROUND: Urethrocutaneous fistula (UCF) formation is a known complication following hypospadias repair, affecting between 5 and 70% of cases. Moreover, approximately 30% of patients experience refistulization after UCF repair. The use of extracellular matrices, such as AmnioCord, a dehydrated human umbilical cord allograft manufactured by MiMedx®, may mitigate high rates of refistulization. OBJECTIVE: To determine whether the use of AmnioCord during UCF repair is associated with reduced incidence of subsequent UCFs among pediatric patients. DESIGN, SETTING, AND PARTICIPANTS: Electronic medical records were retrospectively reviewed among 60 patients who underwent at least one UCF repair at a pediatric hospital in a large urban setting in the U.S. between January 2012-June 2018. Patients were followed through January 2024. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Adjusted generalized estimating equation regression models were used to assess the association between AmnioCord use and rates of refistulization, while controlling for confounding variables. RESULTS: The number of fistula presentations per patient ranged from one to four; 53.3% had one fistula, 30.0% had two, and 16.6% had three or more. Overall fistula repair success rate was 56.8% but significantly differed by AmnioCord use in adjusted modelling; 69.4% of cases that received AmnioCord were successfully repaired, compared to 47.2% of cases that did not receive AmnioCord. In adjusted models, patients who received AmnioCord had 2.66 times greater odds of surgical success than patients who did not receive AmnioCord (95% CI:1.13-6.24; p = 0.02). CONCLUSIONS: This study demonstrates a positive association between AmnioCord use and successful UCF closure among pediatric patients.

Robotic-assisted total knee arthroplasty reduces postoperative complications and length of stay without increased cost compared to navigation-guided techniques: A national analysis.

INTRODUCTION: This study compares postoperative outcomes of robotic-assisted total knee arthroplasty (RA-TKA) versus navigation-guided total knee arthroplasty (NG-TKA). Using Nationwide Inpatient Sample (NIS) data, it provides an analysis of postoperative complications, mortality, hospital costs and duration of stay. METHODS: The study analysed 217,715 patients (81,830 RA-TKA; 135,885 NG-TKA) using NIS data from 2016 to 2019. Elective TKA patients were identified through the International Classification of Diseases, 10th Revision codes. Statistical analyses, including logistic regression modelling, were performed using Statistical Package for the Social Sciences and MATLAB. RESULTS: RA-TKA patients were younger (66.1 vs. 67.1 years, p < 0.0001) and had similar mortality rates (0.024% vs. 0.018%, p = 0.342) but shorter length of stay (LOS) (1.89 vs. 2.1 days, p < 0.0001). Mean total charges were comparable between RA-TKA ($66,180) and NG-TKA ($66,251, p = 0.669). RA-TKA demonstrated lower incidences of blood-related complications (11.67% vs. 14.19%, p < 0.0001), pulmonary oedema (0.0306% vs. 0.066%, p < 0.0001), deep vein thrombosis (0.196% vs. 0.254%, p = 0.006) and acute kidney injury (AKI) (1.356% vs. 1.483%, p = 0.016). CONCLUSION: RA-TKA reduces postoperative complications and LOS without increasing costs, highlighting the relevance of this technology in patient care. LEVEL OF EVIDENCE: Level III.

Urolithiasis diagnosed with endovaginal ultrasound after vaginal prolapse repair surgery using mesh: A case report.

Pain after vaginal prolapse repair surgery with mesh is generally attributed to the mesh fixation, particularly to mesh erosion, dislocation or the development of hematoma. However, once all the causes have been excluded, the urinary system, bladder and ureters should be accurately examined by means of endovaginal ultrasound. This report concerns the case of a 72-year-old woman who had undergone mesh-supported prolapse surgery 3 months prior, with no other relevant diseases, who visited the emergency department complaining of dull, right-sided colic pain. The endovaginal ultrasound examination revealed a prevesical ureteral calculus on the right side with consequent dilatation of the proximal ureter. Computed tomography of the abdomen and pelvis confirmed the calculus in the distal right ureter and revealed a right renal lower pole calculus. The patient underwent treatment via an operative ureterorenoscopy with removal of stones and placement of a double-J-stent. Two months later, a second ureterorenoscopy was performed with double-J-stent removal and concomitant stone extraction. It appears that no similar cases have been reported in the literature. This is why, during the urogynecological postoperative follow-up, it is of paramount importance to examine the entire urogenital system with endovaginal ultrasound. This case report highlights how, through a simple, non-invasive, radiation-free examination, like ultrasound, most of the post-operative complications of vaginal prolapse repair surgery using mesh, including urolithiasis, can be excluded.

Comparison of the effect of combined usage of povidone-iodine irrigation and topical vancomycin powder to the use of povidone-iodine irrigation alone on the periprosthetic joint infection incidence rate in patients undergoing primary total hip and knee arthroplasty: a protocol for multicenter prospective randomized clinical trial.

BACKGROUND: With the increasing number of joint replacement surgeries, periprosthetic joint infection (PJI) has become a significant concern in orthopedic practice, making research on PJI prevention paramount. Therefore, the study will aim to compare the effect of combined usage of povidone-iodine and topical vancomycin powder to the use of povidone-iodine alone on the PJI incidence rate in patients undergoing primary total hip (THA) and total knee arthroplasty (TKA). METHODS: The prospective randomized clinical trial will be conducted in two independent voivodeship hospitals with extensive experience in lower limb arthroplasties. The studied material will comprise 840 patients referred to hospitals for primary THA or TKA. The patients will be randomly allocated to two equal groups, receiving two different interventions during joint replacement. In group I, povidone-iodine irrigation and consecutively topical vancomycin powder will be used before wound closure. In group II, only povidone-iodine lavage irrigation will be used before wound closure. The primary outcome will be the incidence rate of PJI based on the number of patients with PJI occurrence within 90 days after arthroplasty. The occurrence will be determined using a combined approach, including reviewing hospital records for readmissions and follow-up phone interviews with patients. The infection will be diagnosed based on Musculoskeletal Infection Society criteria. The chi-square test will be used to compare the infection rates between the two studied groups. Risk and odds ratios for the between-groups comparison purposes will also be estimated. Medical cost analysis will also be performed. DISCUSSION: A randomized clinical trial comparing the effect of combined usage of povidone-iodine irrigation and vancomycin powder to the use of povidone-iodine irrigation alone in preventing PJIs after primary arthroplasty is crucial to advancing knowledge in orthopedic surgery, improving patient outcomes, and guiding evidence-based clinical practices.

Risk Analysis Index Frailty Score as a Predictor of Otolaryngology Surgical Outcomes.

OBJECTIVE: The Risk Analysis Index (RAI) score is a screening tool to assess patient frailty. It has been shown to be predictive of postoperative outcomes and mortality in orthopedic, urologic, and neurosurgical patient populations. We sought to evaluate the predictive ability of RAI score for surgical outcomes in an otolaryngology patient population. STUDY DESIGN: Retrospective study. SETTING: Academic tertiary medical center. METHODS: A retrospective study was conducted of adult patients undergoing otolaryngology surgery at a tertiary medical care center over 21 months. Patients were sent electronic RAI survey questionnaires via direct messaging, which was completed prior to surgery. Endpoint data were analyzed, including demographics, RAI score, and patient outcome data. Univariate analysis, ROC curves, and predictive modeling were utilized. RESULTS: A total of 517 patients responded to the RAI questionnaire, resulting in a 59.6% response rate. Mean RAI score was 21.38 ± 11.83. Higher RAI scores were associated with increased 30-day readmissions (P < .0015), postoperative complications (P < .001), hospital length of stay (P < .001), and discharge with home health (P < .001). Predictive models for RAI score and postoperative outcomes were created, and a cutoff score of RAI = 30 was established to identify frail patients. CONCLUSION: We evaluated if RAI scoring predicted postoperative complications in an otolaryngology patient population. Increased RAI score is significantly associated with poorer surgical outcomes, including increased hospital length of stay, 30-day readmissions, and postoperative complications. We propose a predictive model with suggested RAI cutoff scoring for use in the otolaryngology surgical population.

Endoscopic ultrasound-guided biliary drainage vs percutaneous transhepatic bile duct drainage in the management of malignant obstructive jaundice.

BACKGROUND: Malignant obstructive jaundice (MOJ) is a condition characterized by varying degrees of bile duct stenosis and obstruction, accompanied by the progressive development of malignant tumors, leading to high morbidity and mortality rates. Currently, the two most commonly employed methods for its management are percutaneous transhepatic bile duct drainage (PTBD) and endoscopic ultrasound-guided biliary drainage (EUS-BD). While both methods have demonstrated favorable outcomes, additional research needs to be performed to determine their relative efficacy. AIM: To compare the therapeutic effectiveness of EUS-BD and PTBD in treating MOJ. METHODS: This retrospective analysis, conducted between September 2015 and April 2023 at The Third Affiliated Hospital of Soochow University (The First People's Hospital of Changzhou), involved 68 patients with MOJ. The patients were divided into two groups on the basis of surgical procedure received: EUS-BD subgroup (n = 33) and PTBD subgroup (n = 35). Variables such as general data, preoperative and postoperative indices, blood routine, liver function indices, myocardial function indices, operative success rate, clinical effectiveness, and complication rate were analyzed and compared between the subgroups. RESULTS: In the EUS-BD subgroup, hospital stay duration, bile drainage volume, effective catheter time, and clinical effectiveness rate were superior to those in the PTBD subgroup, although the differences were not statistically significant (P > 0.05). The puncture time for the EUS-BD subgroup was shorter than that for the PTBD subgroup (P < 0.05). Postoperative blood routine, liver function index, and myocardial function index in the EUS-BD subgroup were significantly lower than those in the PTBD subgroup (P < 0.05). Additionally, the complication rate in the EUS-BD subgroup was lower than in the PTBD subgroup (P < 0.05). CONCLUSION: EUS-BD may reduce the number of punctures, improve liver and myocardial functions, alleviate traumatic stress, and decrease complication rates in MOJ treatment.

Sarcopenia adversely impacts clinical outcomes in patients undergoing pancreaticoduodenectomy: A systematic review and meta-analysis.

BACKGROUND: Sarcopenia is a syndrome marked by a gradual and widespread reduction in skeletal muscle mass and strength, as well as a decline in functional ability, which is associated with malnutrition, hormonal changes, chronic inflammation, disturbance of intestinal flora, and exercise quality. Pancreatoduodenectomy is a commonly employed clinical intervention for conditions such as pancreatic head cancer, ampulla of Vater cancer, and cholangiocarcinoma, among others, with a notably high rate of postoperative complications. Sarcopenia is frequent in patients undergoing pancreatoduodenectomy. However, data regarding the effects of sarcopenia in patients undergoing pancreaticoduodenectomy (PD) are both limited and inconsistent. AIM: To assess the influence of sarcopenia on outcomes in patients undergoing PD. METHODS: The PubMed, Cochrane Library, Web of Science, and Embase databases were screened for studies published from the time of database inception to June 2023 that described the effects of sarcopenia on the outcomes and complications of PD. Two researchers independently assessed the quality of the data extracted from the studies that met the inclusion criteria. Meta-analysis using RevMan 5.3.5 and Stata 14.0 software was conducted. Forest and funnel plots were used, respectively, to demonstrate the outcomes of the sarcopenia group vs the non-sarcopenia group after PD and to evaluate potential publication bias. RESULTS: Sixteen studies encompassing 2381 patients were included in the meta-analysis. The patients in the sarcopenia group (n = 833) had higher overall postoperative complication rates [odds ratio (OR) = 3.42, 95% confidence interval (CI): 1.95-5.99, P < 0.0001], higher Clavien-Dindo class ≥ III major complication rates (OR = 1.41, 95%CI: 1.04-1.90, P = 0.03), higher bacteremia rates (OR = 4.46, 95%CI: 1.42-13.98, P = 0.01), higher pneumonia rates (OR = 2.10, 95%CI: 1.34-3.27, P = 0.001), higher pancreatic fistula rates (OR = 1.42, 95%CI: 1.12-1.79, P = 0.003), longer hospital stays (OR = 2.86, 95%CI: 0.44-5.28, P = 0.02), higher mortality rates (OR = 3.17, 95%CI: 1.55-6.50, P = 0.002), and worse overall survival (hazard ratio = 2.81, 95%CI: 1.45-5.45, P = 0.002) than those in the non-sarcopenia group (n = 1548). However, no significant inter-group differences were observed regarding wound infections, urinary tract infections, biliary fistulas, or postoperative digestive bleeding. CONCLUSION: Sarcopenia is a common comorbidity in patients undergoing PD. Patients with preoperative sarcopenia have increased rates of complications and mortality, in addition to a poorer overall survival rate and longer hospital stays after PD.

A retrospective study on the efficacy of the ERAS protocol in patients who underwent laparoscopic left and right colectomy surgeries.

Objective: Retrospective analysis and comparison of the effects of Enhanced Recovery After Surgery (ERAS) protocol for patients having left and right colectomy surgeries. Method: Out of the patients admitted to Chengdu Shang Jin Nan Fu Hospital and West China Hospital from December 2019 to December 2022, a total of 498 who met the inclusion criteria were selected, 255 with right colectomy(RC) and 243 with left colectomy (LC). Under the conditions of strict compliance with ERAS protocol, the relevant physical indexes of RC and LC, including postoperative rehabilitation (especially median post-operative stay) and complications (especially prolonged postoperative ileus, PPOI), were statistically analyzed and compared. Results: In terms of intraoperative variables, fluid doses were higher in the LC group than in the RC group (P < 0.05), and there was no significant difference between them in terms of operative time, blood loss, need for open surgery, peritoneal contamination, epidural catheter placement, or opioid use (P > 0.05). Compared with the RC group, the LC group had a higher intake of oral liquid at the second postoperative day (POD), and faster first flatulence (P < 0.05). 30 (11.76%) RC patients required nasogastric tube insertion, while only 3 (1.23%) patients in the LC group required the same (P < 0.05). Prolonged postoperative ileus (PPOI) occurred in 48 (18.82%) and 29 (11.93%) patients in the RC and LC groups, respectively (P < 0.05). No significant differences in terms of postoperative complications or length of hospital stay (LoS). stay were observed. Conclusion: As the location of colon cancer changes, the effectiveness of ERAS also varies. More personalized and precise ERAS protocols can reduce the incidence of postoperative complications and promote rapid recovery after surgery.

Revision Total Hip Arthroplasty: Evaluating the Utility of the Geriatric Nutritional Risk Index as a Risk Stratification Tool.

Background: This study investigates the association between the Geriatric Nutritional Risk Index (GNRI), a measure of malnutrition risk, and 30-day postoperative complications following revision total hip arthroplasty (rTHA). Methods: The American College of Surgeons National Surgical Quality Improvement Program database was queried for all patients ≥65 who underwent aseptic rTHA between 2015 and 2021. The final study population (n = 7119) was divided into 3 groups based on preoperative GNRI: normal/reference (GNRI >98) (n = 4342), moderate malnutrition (92 ≤ GNRI ≤98) (n = 1367), and severe malnutrition (GNRI <92) (n = 1410). Multivariate logistic regression analysis was conducted to investigate the association between preoperative GNRI and 30-day postoperative complications. Results: After controlling for significant covariates, the risk of experiencing any postoperative complications was significantly higher with both moderate (odds ratio [OR] 2.08, P < .001) and severe malnutrition (OR 8.79, P < .001). Specifically, moderate malnutrition was independently and significantly associated with deep vein thrombosis (OR 1.01, P = .044), blood transfusions (OR 1.78, P < .001), nonhome discharge (OR 1.83, P < .001), readmission (OR 1.27, P = .035), length of stay >2 days (OR 1.98, P < .001), and periprosthetic fracture (OR 1.54, P = .020). Severe malnutrition was independently and significantly associated with sepsis (OR 3.67, P < .001), septic shock (OR 3.75, P = .002), pneumonia (OR 2.73, P < .001), urinary tract infection (OR 2.04, P = .002), deep vein thrombosis (OR 1.01, P = .001), pulmonary embolism (OR 2.47, P = .019), acute renal failure (OR 8.44, P = .011), blood transfusions (OR 2.78, P < .001), surgical site infection (OR 2.59, P < .001), nonhome discharge (OR 3.36, P < .001), readmission (OR 1.69, P < .001), unplanned reoperation (OR 1.97, P < .001), length of stay >2 days (OR 5.41, P < .001), periprosthetic fractures (OR 1.61, P = .015), and mortality (OR 2.63, P < .001). Conclusions: Malnutrition has strong predictive value for short-term postoperative complications and has potential as an adjunctive risk stratification tool for geriatric patients undergoing rTHA.

Non-Tobacco Nicotine dependence associated with increased Postoperative Complications following Intramedullary Nailing for Intertrochanteric Femur Fractures.

Objectives: Nicotine usage is known to increase postoperative complications; however, studies show that the general population believes that non-tobacco nicotine delivery devices are a safer option compared to tobacco-based nicotine products. This study evaluates postoperative complications between non-tobacco nicotine dependent and non-nicotine dependent patients for intramedullary nailing in intertrochanteric femur fractures. Methods: Utilizing the TriNetX database, we retrospectively examined postoperative outcomes in patients aged 18 to 90 who underwent intramedullary nailing for intertrochanteric femur fractures between November 21, 2013, and November 21, 2023. Two cohorts were analyzed: Cohort A comprised nicotine-dependent patients without tobacco product usage (e.g. cigarettes or chewing tobacco) and Cohort B consisted of patients without any nicotine dependence. Propensity matching was performed for BMI, type 2 diabetes, alcohol/substance abuse, socioeconomic status, and demographic factors. Outcomes assessed included mortality, sepsis, pneumonia, revision, dehiscence, pulmonary embolism, nonunion, and deep vein thrombosis within 1 day to 6 months post-treatment. Results: A total of 2,041 non-tobacco nicotine dependent patients were matched with 22,872 non-nicotine dependent patients. Non-tobacco nicotine dependent patients experienced higher associated risk for numerous postoperative complications compared to non-nicotine dependent patients including increased risk for mortality within 6 months postoperatively (RR 1.386, 10.7% vs 7.7%, P = 0.001), sepsis (RR 1.459, 4.4% vs 3.0%, P = 0.027), and pneumonia (RR 1.751, 5.8% vs 3.3%, P = 0.001). Conclusions: Non-tobacco nicotine dependence increases postoperative complications for patients undergoing intramedullary nailing for intertrochanteric femur fractures. Our findings support the need for development of perioperative nicotine cessation guidelines for non-tobacco nicotine users. Level of evidence: Level III, Prognostic.

Effective Oral Indicators With Medical and Dental Collaboration in Open Heart Surgery: A Representative Survey.

Purpose Postoperative infections pose an important problem for patients with cardiac disease. Moreover, oral health status is associated with the risk of longer hospital stays. Therefore, the oral health status of patients was assessed before open-heart surgery. This study aimed to determine the relationship between oral health status and postoperative status. Methods The study included 25 patients who underwent open-heart surgery at our university hospital in 2020. Upon admission, dentists conducted an oral examination and assessed the oral health status of the patients, also using the Japanese version of the Oral Health Assessment Tool (OHAT-J), Revised Oral Assessment Guide (ROAG), oral moisture level, oral bacteria, and other relevant factors. The study investigated the association with postoperative status. Findings Significant postoperative infections were found in patients aged ≥70 years, with an OHAT-J score of ≥5, OHAT-J lip score of ≥1, Streptococcus γ count of 1.0 × 10^6 or higher (CFU/mL), and increased Streptococcus γ before and after surgery. The duration of hospitalization correlated with the OHAT-J, OHAT-J gum and tissue, and ROAG scores. The duration of intensive care unit (ICU) stays correlated with the OHAT-J score. Conclusions The study demonstrates that OHAT-J scores are linked with predicting not just postoperative infection but also the length of hospitalization and ICU stay. As OHAT-J scores do not necessitate specialized dental instruments, they are straightforward and beneficial for healthcare professionals outside of dentistry.

Home-Based Trimodal Prehabilitation in Patients with Peritoneal Carcinomatosis Undergoing Cytoreductive Surgery: Effect on Functional Walking Capacity and Skeletal Muscle Mass.

BACKGROUND: Patients with peritoneal carcinomatosis often suffer from loss of skeletal muscle mass and require extensive surgery. Multimodal prehabilitation may improve physical status but its benefits for these specific patients remain unknown. This study aimed to evaluate the effect of prehabilitation on functional walking capacity and skeletal muscle mass, as well as its association with postoperative complications. PATIENTS AND METHODS: A prospective study of patients with peritoneal carcinomatosis following a home-based trimodal prehabilitation program was carried out. Functional walking capacity was assessed with the 6-min walk test (T6MWT), and by the appendicular skeletal muscle index (ASMI) estimated by bioelectrical impedance analysis. Data were collected at the first medical appointment and on the day before surgery. A 90-day postoperative morbidity was registered according to the Clavien-Dindo classification. RESULTS: A total of 62 patients were included in the analysis. Women were more prevalent (77.4%) and peritoneal metastasis from ovarian origin accounted for 48.4%. Clavien II-V grades occurred in 30 (57.7%) patients. After prehabilitation, functional walking capacity improved by 42.2 m (39.62-44.72 m) compared with baseline data (p < 0.001), but no improvement was observed in the ASMI (p = 0.301). Patients able to walk at least 360 m after prehabilitation suffered fewer Clavien-Dindo II-V postoperative complications (p = 0.016). A T6MWT of less than 360 m was identified as an independent risk factor in the multivariable analysis (OR 3.99; 1.01-15.79 p = 0.048). CONCLUSIONS: This home-based trimodal prehabilitation program improved functional walking capacity but not ASMI scores in patients with peritoneal metastasis before surgery. A T6MWT of less than 360 m was found to be a risk factor for postoperative complications.

Evaluation of postoperative results after a presurgical optimisation programme.

BACKGROUND: Presurgical optimisation programmes decrease the risk of postoperative complications, reduce hospital stays and speed up patient recovery. They usually involve a multidisciplinary team addressing physical, nutritional and psychosocial issues. The objective of this study was to assess the results of implementing a presurgical optimisation programme led by a liaison nurse in patients undergoing major surgery in a primary general hospital. METHODS: An observational, retrospective, descriptive, cross-sectional, comparative study based on the revision of patients' health records undergoing major surgery between January 2019 and December 2022. Patients entering the presurgical optimisation programme (intervention group) were compared with patients receiving usual medical care (control group). The presurgical optimisation programme consisted of oral nutritional supplementation, physical exercise, strengthening of lung capacity and psychological and emotional support. Frequency (%) of surgery complications and use of healthcare resources (duration of hospitalisation, time spent in the intensive care unit (ICU), and readmission) at day 30 were recorded. Descriptive statistics were applied. RESULTS: Two hundred eleven patients (58.5% men, mean age: 65.76 years (SD 11.5), 75.2%. non-smokers; mean body mass index (BMI): 28.32 (SD 5.38); mean Nutritional Risk Score (NRS) 3.71 (SD 1.35; oncology diagnosis: 88.6%) were included: 135 in the intervention group, and 76 in the control group. The average duration of the presurgical optimisation programme was 20 days (SD 5). Frequency of postoperative complications was 25% (n = 33) in the intervention group and 52.6% (n = 40) in the control group (p < 0.001) [odds ratio (OR) = 3.4; 95% confidence interval (CI) (1.8; 6.2)]. 14.5% (n = 19) of patients in the intervention group and 34.2% (n = 26) in the control group had remote postoperative complications [OR = 3.1; 95% CI (1.6; 6.2)]. Patients in the intervention group spent fewer days in the hospital [mean 8.34 (SD 6.70) vs 11.63 (SD 10.63)], and there were fewer readmissions at 30 days (7.6% vs 19.7%) compared with the control group. CONCLUSIONS: A presurgical optimisation programme led by a liaison nurse decreases the rate of immediate and late surgical complications and reduces hospital stays and readmissions in patients undergoing major surgery.

Instrumentless liver suspension for liver retraction in robotic pancreatoduodenectomy.

The popularity of robotic pancreatoduodenectomy (RPD) is increasing, yet it remains a complex procedure. Outcomes are influenced by various factors, including patient-specific variables, disease characteristics, and surgical technique. Numerous and intricate details contribute to the technical success of RPD. In this study, our focus is on achieving effective and "gentle" liver retraction. The use of liver retractors has been associated with the risk of retractor-related liver injury (RRLI), which can have serious consequences. Here, we introduce a refined technique for instrumentless liver retraction in RPD, developed progressively through a series of over 300 procedures. The core concept of this technique involves suspending the liver to the diaphragmatic dome. This is accomplished by securing the round ligament to the anterior abdominal wall using transparietal sutures and attaching the fundus of the gallbladder and the anterior margin of liver segment number 3 to the diaphragm. Our consecutive series of over 300 RPDs demonstrates the feasibility and safety of this approach, with no clinically relevant RRLI observed. Instrumentless liver retraction offers a valuable refinement in RPD, streamlining the procedure while reducing potential complications associated with dedicated retractors.
