RESUMO
PURPOSE: This research aimed to clarify the metastatic patterns of subcarinal, right and left recurrent laryngeal nerve lymph nodes in thoracic esophageal squamous cell carcinoma and to investigate appropriate strategies for lymph node dissection. METHODS: Patients with thoracic esophageal squamous cell carcinoma receiving esophagectomy from December 2020 to April 2024 were retrospectively analyzed. Risk factors for subcarinal, right and left recurrent laryngeal nerve lymph nodes metastasis were determined by chi-square test and multivariate logistic regression analysis. We visualized the metastasis rates of these specific lymph nodes based on the different clinicopathological characteristics. Correlation between subcarinal, right and left recurrent laryngeal lymph nodes metastasis and postoperative complications were also analyzed. RESULTS: A total of 503 thoracic esophageal squamous carcinoma patients who underwent esophagectomy were enrolled. The metastasis rates of subcarinal, right and left recurrent laryngeal nerve lymph nodes were 10.3%, 10.3%, and 10.9%, respectively. The lymphovascular invasion status and tumor location were the significant predictors for subcarinal and right recurrent laryngeal nerve lymph nodes metastasis, respectively (P < 0.001 and P = 0.013). For left recurrent laryngeal nerve lymph node metastasis, younger age (P = 0.020) and presence of lymphovascular invasion (P = 0.009) were significant risk factors. Additionally, pulmonary infection is the most frequent postoperative complication in patients with dissection of subcarinal, right and left recurrent laryngeal lymph nodes. There was no significant difference in the incidence of anastomotic leakage (P = 0.872), pulmonary infection (P = 0.139), chylothorax (P = 0.702), and hoarseness (P = 0.179) between the subcarinal lymph node dissection cohort and the reservation cohort. The incidence of hoarseness significantly increased in both right (P = 0.042) and left (P = 0.010) recurrent laryngeal nerve lymph nodes dissection cohorts compared by the reservation cohorts, with incidence rates of 5.9% and 6.7%, respectively. CONCLUSIONS: The metastasis rates of subcarinal, right and left recurrent laryngeal nerve lymph nodes in thoracic esophageal squamous cell carcinoma were all over 10%. The dissection of subcarinal lymph nodes does not increase postoperative complications risk, while recurrent laryngeal nerve lymph nodes dissection significantly increases the incidence of hoarseness. Thus, lymph node dissection of subcarinal lymph nodes should be conducted routinely, while recurrent laryngeal nerve lymph nodes dissection may be selectively performed in specific patients.

PURPOSE: Postoperative delirium (POD) is one of the most frequent complications after surgery which is closely associated with many adverse outcomes, including high mortality and low quality of life. This study aims to carry out a bibliometric analysis of POD and its risk factors from 2012 to 2022 to reveal the research status and hot spots. DESIGN: This study is a bibliometric and visualized analysis. METHODS: Relevant publications between 2012 and 2022 were extracted from the Web of Science Core Collection database. CiteSpace software (v6.1. R2, Drexel University), VOSviewer software (v1.6.18, Leiden University), and the Online Analysis Platform of Literature Metrology were used to analyze research attributes. These publications were used to analyze research attributes, including countries, journals, institutions, authors, keywords, and burst detection, to predict trends and hot spots. FINDINGS: We included a total of 1,324 related documents from 2012 to 2022. The literature on POD has increased significantly since 2016. The United States and Harvard University were the leading literature publishing country (436/1324, 32.9%) and institution (112/1324, 8.5%). Anesthesia and Analgesia was the most frequently published journal. Keywords analysis with VOSviewer revealed that the keywords could be divided into five clusters, including anesthesia techniques, cardiac surgery, risk factors, intraoperative anesthesia monitoring, and postoperative cognitive dysfunction. We included a total of 198 POD risk factors documents, and the literature on POD risk factors increased. The People's Republic of China and Harvard University were the leading literature publishing country (53/198, 26.8%) and institution (12/198, 6.1%). Elderly, hip surgery, frailty, postoperative pain, cardiac surgery, dementia, and depression are keywords that are risk factors for POD. CONCLUSIONS: The number of literature on POD in the field of anesthesia has increased significantly. Risk factors and anesthesia techniques are still key areas of research. Encephalogram, the use of sedatives, and perioperative nursing may be the new research focus. Older adults, hip fractures, cardiac surgery, liver transplants, dementia, and depression are hot words in the field of POD risk factors.
RESUMO
BACKGROUND: This study aimed to assess the impact of peritoneal drainage and its type on prognosis, encompassing postoperative recovery and complications, in pediatric patients (≤ 16 years old) following appendectomy based on the grade of appendicitis. METHODS: In this retrospective study, we analyzed pediatric patients (≤ 16 years old) with appendicitis who met the inclusion and exclusion criteria in our center from January 2017 to January 2024 and classified them into grade I-V based on the grade of appendicitis, with V representing the most serious cases. The patients were grouped according to drainage status and type. The main clinical outcomes included postoperative rehabilitation indexes such as time to resume a soft diet, time to remove the drain, duration of postoperative antibiotic use and length of hospitalization (LOH), as well as postoperative complications including intra-abdominal abscess (IAA), ileus and wound infection (WI), and readmission within 30 days after surgery. RESULTS: A total of 385 pediatric patients with appendicitis were included in the study and divided into No-drainage (ND) group (n = 74), Passive drainage (PD) group (n = 246) and Active drainage (AD) group (n = 65) according to drainage status and type. Compared to the other two groups, the ND group had a significantly shorter time to resume a soft diet, duration of postoperative antibiotic use and LOH, and these differences were statistically significant. Similar findings were observed in grade I patients too (P < 0.05). In all cases examined here, the AD group had a significantly shorter time for drain removal compared to the PD group (3.04 [1-12] vs 2.74 [1-15], P = 0.049); this difference was also evident among grade I patients (2.80 [1-6] vs 2.47 [1-9], P = 0.019). Furthermore, within the same grade, only in grade IV did the AD group exhibit a shorter duration of postoperative antibiotic use compared to the PD group (4.75 [4-5] vs 8.33 [5-15], P = 0.009). Additionally, the LOH in the AD group was longer than that in the PD group (8.00 [4-13] vs 4.75 [4-5], P = 0.025). Among all cases, the ND group exhibited significantly lower incidences of overall complications and WI compared to the other two groups (P < 0.05). Additionally, the incidence of IAA in the ND group was significantly lower than that in the PD group (0% vs 5.3%, P = 0.008 < 0.0167). Furthermore, although there were no statistically significant differences in the incidence of overall complications, IAA, ileus, and WI between the PD and AD groups during grade ≥ II analysis (P > 0.05), a higher readmission rate within 30 days was observed in the PD group compared to the AD group; however, these differences were not statistically significant (P > 0.05). Moreover, multivariate analysis revealed that a higher grade of appendicitis was associated with an increased risk of overall complications and IAA as well as a longer duration of postoperative antibiotic use and LOH. CONCLUSION: The appendicitis grade is a crucial indicator for predicting postoperative IAA and LOH. In patients with grade I appendicitis, peritoneal drainage, even if active drainage, is not recommended; For patients with grade ≥ II appendicitis, active drainage may be more effective than passive drainage in reducing the duration of postoperative antibiotic use and LOH.

OBJECTIVE: Interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) are inflammatory cytokines produced in response to biological invasion or infection. Their levels are elevated in the blood and locally. We examined whether measuring IL-6 and TNF-α levels in serum or drainage fluid on postoperative day (POD) 1 could detect infectious complications after minimally invasive surgery for gastric cancer. METHODS: This cohort study included 205 consecutive patients who underwent laparoscopic or robot-assisted gastrectomy for gastric cancer between November 2020 and July 2023. We measured serum and drainage fluid IL-6 and TNF-α levels on POD 1 after gastrectomy. Receiver operating characteristic (ROC) curves were created to compare the diagnostic values of each cytokine and serum C-reactive protein levels for detecting postoperative infectious complications. RESULTS: IL-6 and TNF-α levels in the serum or drainage fluid were significantly higher in patients with an infectious complication. In addition, drainage fluid IL-6 levels were significantly different in patients with versus without intra-abdominal abscess. In the ROC curve analysis, serum and drainage fluid IL-6 had the highest AUC values for any infectious complication and intra-abdominal abscess, respectively. POD 1 serum IL-6 level above 47 pg/mL could detect any infectious complication with sensitivity of 74.1 % and specificity of 71.8 %. POD 1 drainage fluid IL-6 level above 14,750 pg/mL had 100 % sensitivity for detecting intra-abdominal abscess with specificity of 56.0 %. CONCLUSIONS: Measurement of IL-6 levels in blood and drainage fluid on POD 1 is valuable for early detection of postoperative infectious complications or intra-abdominal abscess after gastric cancer surgery.
RESUMO
INTRODUCTION: Acute care surgeons are experts in trauma treatment, emergency surgery, and critical surgical care. Here, we analyzed the association of acute care surgeons on postoperative outcomes of emergency general surgery. METHODS: This retrospective study included 92 patients who underwent emergency general surgery at our institution between January 2020 and September 2021. Propensity score matching was used to analyze postoperative outcomes. The primary outcome was postoperative complications, while secondary outcomes included perioperative management and surgery-related and postoperative complications. Logistic regression analysis was used to estimate the odds ratios for all complications. In this study, acute care surgeons were defined as acute care surgery (ACS)-certified surgeons by the Japanese Society for Acute Care Surgery. RESULTS: Overall, 30 patients were treated by an acute care surgeon and general surgeons (ACS group), and 62 patients were treated by general surgeons (non-ACS group), respectively. Propensity score matching identified 30 patients with balanced baseline covariates, in each group. The ACS group had lower complication rates (Clavien-Dindo classification ≥2) than the non-ACS group (17% versus 40%, P = 0.08). The ACS group had a significantly shorter surgery duration than the non-ACS group (75 min versus 96 min, P = 0.014). In the logistic analysis, acute care surgeon involvement was identified as an independent predictor for the decrease in all complications (odds ratio, 0.15; 95% confidence interval, 0.02-0.64). CONCLUSIONS: It was suggested that the involvement of acute care surgeons may reduce the overall complication rate in emergency general surgery.
RESUMO
OBJECTIVE: Changes in glucolipid metabolism parameters in patients undergoing renal transplantation (RT) and their influences on the incidence of postoperative complications were analysed. The objective was to provide a reference for clinical practice and reliable and safe implementation of RT. METHODS: A total of 131 patients treated with RT at our institution from January 2019 to March 2024 were selected for retrospective analysis: 71 patients who developed postoperative complications (research group) and 60 patients who did not (control group). Differences in fasting plasma glucose (FPG), glycosylated haemoglobin (HbA1c), total cholesterol (TC) and triglyceride (TG) levels before and three days after surgery were compared, and their predictive value for postoperative complications was analysed. In addition, relevant factors influencing complications after RT were identified. RESULTS: HbA1c level changed significantly in neither group after surgery (p > 0.05), but FPG, TG and TC levels increased in both groups (p < 0.05). Differences in FPG and TC levels before and after surgery were larger than those in the control group (p < 0.05). The receiver operating characteristic curve revealed the excellent diagnostic value of differences in FPG and TC levels for postoperative complications, and logistic regression analysis indicated that such differences were independent risk factors for complications after RT (p < 0.05). CONCLUSIONS: The early evaluation of postoperative complications can be achieved by monitoring differences in FPG and TC levels before and after RT, allowing for the timely formulation and implementation of interventions.

Objective: This study aimed to provide a comprehensive overview of the complications unique to ureteral reconstruction in adults, emphasizing their presentation, diagnosis, and management in the treatment of ureteral structure disease. Methods: This review involves an in-depth analysis of existing literature and case studies pertaining to ureteral reconstruction, with a focus on examining the range of complications that can arise post-surgery. Special attention is given to the presentation of each complication, the diagnostic process involved, and the subsequent management strategies. Results: Ureteral reconstruction can treat ureteral stricture disease with low morbidity; however, complications, although uncommon, can have severe consequences. The most notable complications include urinary extravasation, stricture recurrence, urinary tract infections, compartment syndrome, symptomatic vesicoureteral reflux, and Boari flap necrosis. Each complication presents unique diagnostic challenges and requires specific management approaches. Conclusion: Ureteral reconstruction is a highly effective treatment for ureteral stricture disease. Having a strong understanding of the potential complications that patients may experience following ureteral reconstruction is not only critical to adequately counsel patients but also facilitate prompt diagnosis and management of complications when they arise.
RESUMO
BACKGROUND: Although sublobar resection (wedge resection [Wed] or segmentectomy [Seg]) has become a standard operative procedure for clinical stages IA1 and IA2 non-small cell lung cancer (NSCLC) in Japan, the impact of this procedure on the prognosis and postoperative complications in real-world clinical practice is unknown. METHODS: This study retrospectively analyzed risk factors for a poor prognosis and postoperative complications of 470 patients with clinical stage ≤ IA2 NSCLC who underwent surgery from 2012 to 2021. RESULTS: Among the patients with a consolidation-to-tumor ratio (CTR) higher than 0.5, the 5-year relapse-free survival (RFS) rate was significantly lower in the Wed group (72.1%) than in the Seg (85.8%) and Lob (86.8%) groups (p < 0.01), but the difference between the Seg and Lob groups was not significant. Among patients with a CTR of 0.5 or lower, the 5-year RFS rate did not differ significantly among the three groups. Multivariable analysis of RFS showed that the prognosis was significantly worse in the Wed group than in the Lob group (hazard ratio, 2.83; p < 0.01), but the difference between the Wed and Seg groups or the between Seg and Lob groups was not significant. Multivariable analysis of postoperative complications showed a significantly lower risk in the Wed group than in the Seg group (odds ratio, 0.31; p < 0.01). CONCLUSIONS: Seg could become the standard operative procedure for clinical stages IA1 and IA2 NSCLC patients. Wed is suggested to be an option for patients with a CTR of 0.5 or lower and has the advantage of avoiding postoperative complications.
RESUMO
PURPOSE OF REVIEW: The purpose of this review article is to provide a contemporary overview of benign uretero-enteric anastomotic stricture (UAS) management and outcomes. RECENT FINDINGS: In this article, we will review the most recent studies investigating UAS and evaluate etiology, potential risk factors, presentation, diagnosis, and management options, along with personal insight gained from our experience with managing this challenging reconstructive complication. Benign UAS is a relatively common long-term complication of intestinal urinary diversion, affecting approximately 1 in 10 patients. It is thought to be caused by ureteral tissue ischemia and fibrosis at the anastomotic site. Risk factors appear to include any that increase the likelihood of leak or ischemia; it is not clear if anastomotic approach impacts risk for stricture as well. Management options are varied and include endourologic, open, and robotic approaches. Endoscopic approaches may be less morbid but are considerably less effective than reconstruction performed after a period of ureteral rest.
RESUMO
Background: There are no standard guidelines regarding the number and size of chest tubes that should be selected after thoracic surgery. This study aimed to evaluate the effects of adopting a drainage strategy with bi-pigtail catheters (BPCs) on patients undergoing lobectomy by uniportal video-assisted thoracic surgery (VATS). Methods: A retrospective study was performed of patients undergoing uniportal lobectomy at the Department of Thoracic Surgery of the Cancer Hospital of Dalian University of Technology between August 2021 and August 2022. The patients were divided into the following two groups according to the drainage strategy adopted: (I) a traditional chest tube (TCT) group; and (II) a BPC group. The outcomes measured included postoperative complications, as measured by the Clavien-Dindo method, and the visual analogue scale (VAS) pain scores of the patients after surgery. Results: In total, 868 patients underwent lung resection during the study period, after exclusion, the data of 470 patients who underwent uniport lobectomy were reviewed (235 in the TCT group, and 235 in the BPC group). There were no statistically significant differences between the two groups in terms of baseline data (P>0.05). The incidence of postoperative complications (7.7% vs. 19.1%) and postoperative VAS pain scores at 7-24 hours (3.3±1.0 vs. 3.7±1.5) and 25-48 hours (3.1±0.8 vs. 3.6±1.5) were significantly lower in the BPC group than the TCT group (all P<0.001). Additionally, the postoperative length of stay (4.6±1.5 vs. 5.4±4.5 days) and the collapse rate of the residual lung (19.2%±9.1% vs. 20.9%±9.6%) of the BPC group were better than those of the TCT group (P<0.05). The results of univariable and multivariable analyses showed that a drainage strategy with a TCT was an independent risk factor for decreased postoperative complications, and reduced moderate or severe pain scores at 7-24 and 25-48 hours after surgery. Conclusions: Our drainage strategy with BPCs decreased the incidence of postoperative complications and alleviated the postoperative pain of patients undergoing lobectomy by uniportal VATS and is safe and feasible.
RESUMO
Introduction: The combination of neoadjuvant immunotherapy and chemotherapy (NICT) has become a common treatment regimen for locally advanced gastric cancer (LAGC). However, the safety and efficacy of radical gastrectomy following NICT (NICT-G) remain controversial. This study aimed to analyze the risk factors influencing postoperative complications (POCs) after NICT-G. Additionally, it aimed to construct a nomogram to provide a clinical reference for predicting POCs. Methods: This study included 177 patients who received NICT-G at the Chinese PLA General Hospital First Medical Center from January 2020 to January 2024. Univariable and multivariable logistic regression models were used to evaluate the risk factors influencing POCs, and a nomogram model was constructed. To evaluate the discrimination and accuracy of the nomogram model, the area under the receiver operating characteristic curve (AUC) and the calibration curve were measured. Results: In 177 patients who received NICT-G, the pathological complete response and major pathological response rates were 15.8% and 45.2%, respectively, whereas the rates of the overall and severe treatment-related adverse events were 71.8% and 15.8%, respectively. In addition, 43 (24.3%) patients developed overall POCs (Clavien-Dindo classification ≥ II). Univariable and multivariable logistic analyses showed that age ≥70 years, greater estimated blood loss, platelet/lymphocyte ratio (PLR) ≤196, neutrophil/lymphocyte ratio (NLR) >1.33, non-R0 resection, and body mass index (BMI) < 18.5 kg/m2 were independent risk factors for overall POCs (p < 0.05). The nomogram model developed using the abovementioned variables showed that the AUC (95% confidence interval [CI]) was 0.808 (95% CI): 0.731-0.885 in predicting the POC risk. The calibration curves showed that the prediction curve of the nomogram was a good fit for the actual POCs (Hosmer-Lemeshow test: χ2 = 5.76, P = 0.451). Conclusion: The independent risk factors for overall POCs in the NICT-G were age ≥ 70 years, greater estimated blood loss, PLR ≤ 196, NLR > 1.33, non-R0 resection, and BMI < 18.5 kg/m2. The nomogram model developed based on the abovementioned indicators showed better accuracy in predicting the POC risk.
RESUMO
Splenic artery aneurysm (SAA) is the most common visceral artery aneurysm and can lead to severe outcomes if ruptured. This report presents the case of a 71-year-old female who experienced a sudden and severe gastrointestinal hemorrhage 19 years after undergoing pancreaticoduodenectomy for pancreatic head cancer. The patient arrived at the hospital with signs of shock, and imaging revealed an SAA rupture with associated gastric perforation. Emergency treatment involved endovascular techniques, which stabilized the patient and controlled the bleeding. This case highlights the importance of rapid diagnosis and the effectiveness of endovascular therapy in managing SAA rupture, particularly in patients with complex surgical histories.
RESUMO
BACKGROUND: The relationship between risk factors of common postoperative complications after pulmonary resection, such as air leakage, atelectasis, and arrhythmia, and patient characteristics, including nutritional status or perioperative factors, has not been sufficiently elucidated. METHODS: One thousand one hundred thirty-nine non-small cell lung cancer patients who underwent pulmonary resection were retrospectively analyzed for risk factors of common postoperative complications. RESULTS: In a multivariate analysis, male sex (P = 0.01), age ≥ 65 years (P < 0.01), coexistence of chronic obstructive pulmonary disease (COPD) (P < 0.01), upper lobe (P < 0.01), surgery time ≥ 155 min (P < 0.01), and presence of lymphatic invasion (P = 0.01) were significant factors for postoperative complication. Male sex (P < 0.01), age ≥ 65 years (P = 0.02), body mass index (BMI) < 21.68 (P < 0.01), coexistence of COPD (P = 0.02), and surgery time ≥ 155 min (P = 0.01) were significant factors for severe postoperative complication. Male sex (P = 0.01), BMI < 21.68 (P < 0.01), thoracoscopic surgery (P < 0.01), and surgery time ≥ 155 min (P < 0.01) were significant risk factors for postoperative air leakage. Coexistence of COPD (P = 0.01) and coexistence of asthma (P < 0.01) were significant risk factors for postoperative atelectasis. Prognostic nutrition index (PNI) < 45.52 (P < 0.01), lobectomy or extended resection more than lobectomy (P = 0.01), and surgery time ≥ 155 min (P < 0.01) were significant risk factors for postoperative arrhythmia. CONCLUSION: Low BMI, thoracoscopic surgery, and longer surgery time were significant risk factors for postoperative air leakage. Coexistence of COPD and coexistence of asthma were significant risk factors for postoperative atelectasis. PNI, surgery time, and surgical procedure were revealed as risk factors of postoperative arrhythmia. Patients with these factors should be monitored for postoperative complication. TRIAL REGISTRATION: The Institutional Review Board of Kanazawa Medical University approved the protocol of this retrospective study (approval number: I392), and written informed consent was obtained from all patients.

Background: Recent investigations have suggested that-sidedness is associated with the prognosis of colon cancer patients. However, the role of sidedness in surgical outcome is unclear. In this study, we tried to demonstrate the real role of sidedness in postoperative results for colon cancer patients receiving surgical intervention. Methods: This is a propensity score matching study using the database of the American College of Surgeons-National Surgical Quality Improvement Program (ACS-NSQIP) from 2009 to 2013. Sidedness groups including right-sided and left-sided colon cancer were created according to the associated diagnosis and procedure codes. Postoperative 30-day mortality, morbidity, overall complications, and total length of hospital stay were analyzed after performing propensity score matching. Results: Out of a total of 24,436 colon cancer patients who received associated operations, 15,945 patients had right-sided cancer and 8941 patients had left-sided cancer. Right-sided colon cancer patients were accompanied by more preoperative comorbidities including old age, female sex, hypertension, dyspnea, anemia, hypoalbuminemia, and a high American Society of Anesthesiologists grade (SMD > 0.1). Postoperative mortality, morbidities including re-intubation, bleeding, urinary tract infection and deep vein thrombosis, postoperative overall complications, and total length of hospital stay were significantly associated with right-sided cancer (p < 0.05). After 1:1 propensity score matching, postoperative mortality was not significantly different between right-sided cancer (2.3%) and left-sided cancer (2.4%) patients. The patients with left-sided colon cancer had significantly more postoperative morbidities, more overall complications, and longer total length of hospital stay. Conclusions: Poor clinical characteristics and postoperative outcomes were noted in right-sided cancer patients. After propensity score matching, left-sided cancer patients had worse postoperative outcomes than those with right-sided cancer.
RESUMO
OBJECTIVE: We would like to investigate the prognostic utility of the previously described factors and offer a new parameter called neutrophil-to-C-reactive protein ratio (NCR) as a predictor of post-operative complications of pancreas cancer. METHODS: 92 patients underwent pancreaticoduodenectomy for the pancreatic head tumor were enrolled in this study. Receiver operating curve analysis was performed to detect the cutoff values, and logistic regression analyses were performed to identify the independent risk factors of complications. RESULTS: In univariate analysis, complications were observed in lymphocyte-to-C-reactive protein ratio levels below 0.06 (Odds Ratio [OR]: 3.92, 95% confidence interval [CI] = 1.08-14.21, p = 0.037). In multivariate analysis, albumin < 3.6 (OR: 3.25, 95% CI: 1.16-9.06, p = 0.024) and NCR < 0.28 (OR: 2.81, 95 % CI: 1.07-7.63, p = 0.042) were the independent and significant predictors of the overall survival. DISCUSSION: Quantification of preoperative NCR and albumin may help surgeons to settle an effective perioperative management, take extra caution, and be aware of post-operative complications of pancreatic cancer patients.
OBJETIVO: Se investigó la proporción de neutrófilos a proteína C reactiva (NCR) como predictor de complicaciones posoperatorias del cáncer de páncreas. MATERIAL Y MÉTODOS: 92 pacientes fueron sometidos a pancreaticoduodenectomía (PD) por el tumor de la cabeza del páncreas incluidos en este estudio. Se realizaron análisis de curva operativa del receptor (ROC) y análisis de regresión logística para detectar los valores de corte y los factores de riesgo independientes de complicaciones. RESULTADOS: En análisis univariado; se observaron complicaciones en niveles de LCR por debajo de 0,06 (OR: 3.92, IC 95%: 1.08-14.21, p = 0.037). En análisis multivariado; albúmina < 3.6 (OR: 3.25, IC 95 %: 1.16-9.06, p = 0.024), NCR < 0.28 (OR: 2.81, IC 95 %: 1.07-7.63, p = 0.042) fueron los predictores independientes y significativos de la supervivencia. CONCLUSIÓN: La cuantificación de la NCR y la albúmina preoperatorias puede ayudar a los cirujanos a establecer un manejo perioperatorio efectivo, tomar precauciones adicionales y estar atentos a las complicaciones posoperatorias.

Segmental maxillary osteotomy, a surgical technique used in orthognathic surgery, involves the risk of palatal mucosa tearing, which can lead to severe complications. Herein, we report the case of a woman with Angle class II malocclusion who underwent multiple elective segmental maxillary osteotomy and augmentation genioplasty procedures for the correction of her malocclusion and the enhancement of her facial profile. A week after surgery, the patient developed a palatal ulcer. We adopted a comprehensive treatment approach involving 14-day hyperbaric oxygen therapy and conventional modalities; this approach resulted in favorable outcomes. Our case underscores the importance of immediate intervention and the synergistic potential of the comprehensive approach against oronasal fistula formation. Our findings indicate that hyperbaric oxygen therapy promotes wound healing, particularly in patients with complications arising from maxillofacial surgery.
RESUMO
BACKGROUND: We aimed to investigate the incidence and risk factors of postoperative acute pancreatitis (PAP) following thoracic aortic surgery with circulatory arrest. METHODS: One hundred fifty-two patients who underwent thoracic aortic surgery with circulatory arrest between February 2015 and March 2023 were retrospectively reviewed. Postoperative acute pancreatitis was defined as the presence of two or more of the following criteria: (1) abdominal pain, (2) postoperative amylase or lipase levels greater than three times the upper limit of normal, and (3) evidence of pancreatitis on postoperative computed tomography (CT) scan. Univariate and multivariate analyses were performed to find risk factors for PAP. RESULTS: Nine patients (5.9%) developed PAP without mortality. All of the nine patients had elevated pancreatic enzymes and evidence of pancreatitis on CT. They improved with conservative therapy. In multivariate analysis, only cross-clamp time was found to be a significant risk factor for PAP (adjusted odds ratio, 1.04; 95% confidence interval, 1-1.08; p = 0.042). CONCLUSION: The incidence of PAP after thoracic aortic surgery with circulatory arrest was 5.9%, and cross-clamp time is an independent risk factor for PAP.
RESUMO
Robotic esophagectomy has improved early outcomes and enhanced the quality of lymphadenectomy for esophageal cancer surgery. This study aimed to determine risk factors for long-term survival following robotic esophagectomy and the causes of long-term mortality. We included patients who underwent robotic esophagectomy at our institute between 2010 and 2022. Robotic esophagectomy was defined as a surgical procedure performed robotically in both the abdomen and thorax. Robotic esophagectomy was performed in patients at all stages, including advanced stages, even in patients with stage IV and supraclavicular lymph node metastasis. A total of 340 patients underwent robotic esophagectomy during the study period. Ivor-Lewis operation and McKeown operation were performed on 153 (45.0%) and 187 (55.0%) patients, respectively. The five-year survival rates based on clinical stages were as follows: 85.2% in stage I, 62.0% in stage II, 54.5% in stage III, and 40.3% in stage IV. Risk factors for long-term survival included body mass index, Charlson comorbidity index, clinical stages, and postoperative complications of grade 4 or higher. Among the cases of long-term mortality, recurrence accounted for 42 patients (61.7%), while non-cancer-related death occurred in 26 patients (38.2%). The most common cause of non-cancer-related death was malnutrition and poor general condition, observed in 11 patients (16.2%). Robotic esophagectomy has demonstrated the ability to achieve acceptable long-term survival rates, even in patients with cervical lymph node metastasis. However, addressing high-grade postoperative complications and long-term malnutrition remains crucial for further improving the long-term survival outcomes of patients with esophageal cancer.
RESUMO
Background: Application of hemihepatic inflow occlusion (HIO) and total hepatic inflow occlusion (TIO) are two common approaches for hepatectomy. However, their efficacy and safety remain controversial. Methods: Randomized control trials (RCTs) published before 15t January 2023 were included by a systematic literature search, which compared the clinical outcomes between HIO and TIO. The primary outcome was the estimated blood loss (EBL). Three independent authors screened and extracted the data and resolved disagreements by consensus. The ROB2.0 tool was used for evaluating the risk of bias. Results: A total of 1026 patients (511 TIO and 515 HIO) from 9 studies were analyzed in the meta-analyses. The EBL between TIO and HIO group was similar, while HIO was associated with a lower proportion of patients required transfusion (P=0.002), less units of blood transferred (P<0.001) and a lower overall complication rate (P=0.008). There were no significant differences between TIO and HIO in mortality (P=0.37), length of stay (P=0.97), bile leak rate (P=0.58), liver failure rate (P=0.96), reoperation rate (P=0.48), postoperative haemorrhage rate (P=0.93) and incidence of postoperative ascites (P=0.96). The operative time of HIO was usually no more than 15 min longer than that of TIO (P<0.001). Conclusions: Comparing with the TIO, HIO increased the operative time and failed to further reduce the EBL in patients with liver surgery. However, despite the complexity of the operation, HIO was recommended due to the similar effect on the consumption of blood products and the postoperative complications.
