Outcome of Cataract Surgery in Patients With Retinitis Pigmentosa

To assess the visual outcome of cataract surgery in patients with retinitis pigmentosa (RP). Retrospective, noncomparative clinical study. Preoperative, intraoperative, and postoperative data of patients with RP who were undergoing cataract surgery were collected from several expertise centers across Europe. In total, 295 eyes of 225 patients were included in the study. The mean age at surgery of the first eye was 56.1 ± 17.9 years. Following surgery, best-corrected visual acuity (BCVA) improved significantly from 1.03 to 0.81 logMAR (ie, 20/214 to 20/129 Snellen) in the first treated eye (-0.22 logMAR; 95% CI=-0.31 to -0.13; P < .001) and from 0.80 to 0.56 logMAR (ie, 20/126 to 20/73 Snellen) in the second treated eye (-0.24 logMAR; 95% CI=-0.32 to -0.15; P < .001). Marked BCVA improvements (postoperative change in BCVA of ≥0.3 logMAR) were observed in 87 of 226 patients (39%). Greater odds for marked visual improvements were observed in patients with moderate visual impairment or worse. The most common complications were zonular dialysis (n=15; 5%) and (exacerbation of) cystoid macular edema (n=14; 5%), respectively. Postoperative posterior capsular opacifications were present in 111 of 295 eyes (38%). Significant improvements in BCVA are observed in most patients with RP following cataract surgery. Baseline BCVA is a predictor of visual outcome. Preoperative evaluation should include the assessment of potential zonular insufficiency and the presence of CME, as they are relatively common and may increase the risk of complications.

Identifying the long-term survival beneficiary of chemotherapy for stage N1c sigmoid colon cancer

Sigmoid colon cancer often has an unsatisfactory prognosis. This study explored the effect of tumor deposits (TDs) on survival, and whether their presence/absence influence individualized treatment. Data of postoperative patients with sigmoid colon cancer were extracted from the Surveillance, Epidemiology, and End Results database. Overall survival (OS) was calculated using the Kaplan–Meier method and prognostic factors were identified using Cox regression analysis and random forest (RF). The nomogram's discrimination performance was evaluated using a concordance index (C-index), integrated discrimination improvement (IDI), calibration curves, and decision-curve analysis. The N1c group showed a worse prognosis than the N0 group. For N1c patients, a combination of surgery and chemotherapy prolonged survival, compared to surgery alone; however, the chemotherapy-surgery combination did not affect the OS of patients younger than 70 years, in stage T1–2, and/or of black race. Multivariable analysis and RF presented Age, T stage, and N stage were the most important predictors for OS. The novel nomogram had superiority to the TNM staging system with improved C-index and IDI, as well as good consistency and higher clinical benefit. TDs are associated with poor survival from sigmoid colon cancer, and considering TDs can inform the formulation of individual treatment regimens. The nomogram shows satisfactory prediction ability for OS.

Feasible management of median arcuate ligament syndrome in orthotopic liver transplantation recipients.

BACKGROUNDIn orthotopic liver transplantation (OLT) recipients, median arcuate ligament syndrome (MALS) is considered a risk factor for hepatic arterial thrombosis (HAT), which is dreadful for OLT recipients. Different alternative surgical procedures have been proposed to overcome the impact of MALS on transplantation, but clinical evidence is still scarce. AIMTo evaluate the feasible surgical management of MALS to reduce complications in OLT patients.METHODSData for 288 consecutive patients who underwent OLT at The First Hospital of Jilin University between January 2017 and July 2020 were retrospectively reviewed. The surgical management of median arcuate ligament (MAL) and modifications to the arterial anastomosis were recorded. The perioperative and long-term prognosis of MALS recipients were noted. Detailed preoperative and postoperative data of patients were analyzed in a descriptive manner.RESULTSEight patients with MALS were included in this study. The first patient with MALS received no intervention during the primary surgery and developed postoperative HAT. Salvage liver transplantation with MAL division was successfully performed. Gastroduodenal artery (GDA) preservation with splenic artery ligation was performed on three patients, only GDA preservation was performed on two patients, and no intervention was performed on two patients. No patient developed HAT after surgery and postoperative recovery was satisfactory. CONCLUSIONThe preservation of collateral circulation between the superior mesenteric artery and celiac trunk via the GDA with or without splenic artery ligation is a safe and feasible alternative to MAL division.

EP05.02-005 Is Immunotherapy Safer Than Radiotherapy in Combination With Chemotherapy in Neoadjuvant Therapy?

Surgery in locally advanced lung cancer can be performed safely with neoadjuvant treatment preparation. Perioperative and postoperative characteristics and survival data of patients differ with changing parameters in neoadjuvant treatment modalities. We aimed to analyze the pathological response, complication and survival data with different combinations of neoadjuvant therapy.

Predictive role of shock index in the early formation of cerebral infarction in patients with TBI and cerebral herniation.

Background and purposeTraumatic brain injury (TBI) with brain herniation predisposes to posttraumatic cerebral infarction (PTCI), which in turn seriously affects the prognosis of patients. At present, there is a lack of effective indicators that can accurately predict the occurrence of PTCI. We aimed to find possible risk factors for the development of PTCI by comparing the preoperative and postoperative clinical data of TBI patients with brain herniation.MethodsThe clinical data of 120 patients with craniocerebral trauma and brain herniation were retrospectively analyzed. Among them, 54 patients had cerebral infarction within 3–7 days after injury. The two groups of patients were compared through univariate and multivariate logistic regression analysis, and a classification tree model and a nomogram model were constructed. Finally, receiver operating characteristic curve analysis and decision curve analysis were conducted to analyze the clinical utility of the prediction model.ResultsLogistic regression analysis showed that factors like the Glasgow Coma Scale (GCS) score (P = 0.002), subarachnoid hemorrhage (SAH) (P = 0.005), aspiration pneumonia (P < 0.001), decompressive craniectomy (P < 0.05), intracranial pressure (ICP) monitoring (P = 0.006), the shock index (SI) (P < 0.001), the mean arterial pressure (MAP) (P = 0.005), and blood glucose (GLU) (P < 0.011) appeared to show a significant statistical correlation with the occurrence of infarction (P < 0.05), while age, sex, body temperature (T), D-dimer levels, and coagulation tests were not significantly correlated with PTCI after cerebral herniation. Combined with the above factors, Classification and Regression Tree was established, and the recognition accuracy rate reached 76.67%.ConclusionsGCS score at admission, no decompressive craniectomy, no ICP monitoring, combined SAH, combined aspiration pneumonia, SI, MAP, and high GLU were risk factors for infarction, of which SI was the primary predictor of PTCI in TBI with an area under the curve of 0.775 (95% CI = 0.689–0.861). Further large-scale studies are needed to confirm these results.

Central and mixed sleep apnea related to patients treated with maxillomandibular advancement for obstructive sleep apnea: A retrospective cohort study

The aim of this study was to evaluate the clinical efficacy of maxillomandibular advancement (MMA) for obstructive sleep apnea (OSA) patients with a percentage of central and mixed apnea index in the total apnea−hypopnea index (CMAI%) ≧25%.Patients treated with MMA for OSA were retrospectively evaluated for baseline and postoperative patient data and polysomnographic results. The pre- and postoperative obstructive, central and mixed apnea parameters were compared.Of the included 78 patients, 21 patients (27%) presented with CMAI% ≧25% (median CMAI%, 49.1%; 35.9–63.8) prior to MMA. In 67% of these cases, MMA resulted in CMAI% <25 (median CMAI%, 6.1%; 2.1–8.9) and significantly improved the apnea−hypopnea index (AHI) (p < 0.001), the lowest oxyhemoglobin saturation (p < 0.001), central and mixed apnea index (p < 0.001), percentage of central and mixed apneas of total AHI (p = 0.004), central apnea index (p < 0.001), and mixed apnea index (p < 0.001). CMAI% ≧25% emerged in 25% of patients after MMA (median CMAI%, 49.1%; 35.9–63.8).Within the undeniable limitations of the study, it seems that the presence of CMAI% ≧25% should not be regarded as a contraindication for MMA in OSA patients.

A New Safe and Ergonomic Manipulation Tool for the Flank-Free Supine Position: "U-Pad".

Introduction: One of the most important problems in the supine percutaneous approach to the kidney is the narrow surgical surface area (SSA) in the lumbar region. Herein, the spatial and angular geometric advantages of the U-shaped lumbar pad (U-Pad) used as a new positioning tool for safety and ergonomics in the supine percutaneous approach have been revealed. Materials and Methods: Data of patients who underwent endoscopic combined intrarenal surgery (ECIRS) using the U-Pad for kidney stones between March and September 2021 were prospectively collected. The demographic, preoperative, operative, and postoperative data of patients have been saved. The patients were positioned first with the standard gel pad (group 1) and then with the U-Pad (group 2). Both SSA (X and X+Y, cm2) and angular degree (α and β,°) calculations were compared. Fluoroscopy images with the same settings (97 kV/3.00 mA) were visually compared. In geometric data, trapezoidal area formula [(upper base + lower base) × height/2] and goniometer were used to compare with paired t-test. Results: ECIRS was performed on 17 patients, 13 men and 4 women, with a median age of 39 (range 32-47). The median body mass index was 26.2 (23.5-29.1). Stone localization and features were recorded. The median SSA was calculated as 35.7 cm2 in group 1 and 97.3 cm2 in group 2, and it was calculated that the total SSA increased to 272.5% with a median of 61.6 cm2 extra surgical area. Similarly, the downward manipulation angle was 32° (α°) in group 1, whereas it was 60.6° (β°) in group 2, and the median extra motion angle was calculated as 28.6° (89.3%). Conclusion: The U-Pad is a safe and rapid tool in the supine percutaneous approach to the kidney, providing at least two times the extra SSA and manipulation angle.

Comparison of retroperitoneal and transperitoneal surgical routes in laparoscopic nodal staging for locally advanced cervical cancers (FIGO IB3-IVA)

BackgroundThis study compares morbidity and mortality associated with retroperitoneal and transperitoneal para-aortic lymphadenectomy (PAAL) for pretherapeutic nodal staging of locally advanced cervical cancers (FIGO IB3–IVA). MethodsPre-, per- and postoperative data of patients treated for locally advanced stage cervical cancer between 1999 and 2018 in 12 French referral centers (FRANCOGYN Study Group) were retrospectively collected. ResultsThe study was conducted using a sample of 448 patients, of whom 223 (49,8%) underwent retroperitoneal (group 1) and 225 (50,2%) had transperitoneal PAAL (group 2). No differences were noted concerning clinical and histological characteristics between the two groups. Among these 448 patients, 23 (5,1%) had an intraoperative complication (9 (2,0%) in group 1 and 14 (3,1%) in group 2, p = 0.28) and 47 (10,5%) had a postoperative complication (22 (4,9%) in group 1 and 25 (5,6%) in group 2, p = 0.44), only one of which required revision surgery but the patient died. The length of hospital stay was significantly shorter in group 1 than in group 2 (3.97 versus 4.88 days, p < 0.001). There was no significant difference in mortality between the two groups; 34 of 223 patients in group 1 (15.3%) and 40 of 225 patients in group 2 (15.6%) died (HR = 0.968, 95% CI [0.591–1.585]). There was no significant difference in recurrence-free or overall survival between the two groups. ConclusionRetroperitoneal PAAL appears as a valuable and safety surgical route for nodal staging in locally advanced cervical cancer compared with standard transperitoneal PAAL.

A novel four-gene signature for predicting the prognosis of hepatocellular carcinoma

Objective To identify and utilize gene signatures for the prognostic evaluation of postoperative patients with hepatocellular carcinoma (HCC). Methods The gene mRNA expression profiles and corresponding clinicopathological data of postoperative patients with HCC were downloaded from The Cancer Genome Atlas (TCGA) database. Highly differentially expressed genes (DEGs) in tumor tissues compared to adjacent tissues were identified, and their associations with the overall survival (OS) of HCC patients were analyzed. The strongly associated genes were used to develop a prognostic score for the survival stratification of HCC, and the underlying mechanisms were analyzed using bioinformatics. Results A total of 376 DEGs were identified and four DEGs (ADH4, COL15A1, RET and KCNJ16) were independently associated with OS. A prognostic score derived from the four genes could effectively stratify HCC patients with different OS outcomes, independent of clinical parameters. Patients with high scores exhibited poorer OS than patients with low scores (HR 5.526, 95% CI: 2.451–12.461, p < .001). The four genes were involved in cancer-related biological processes and were independent of each other in bioinformatics analyses. Conclusion Four genes strongly associated with the prognosis of postoperative patients with HCC were identified, and the derived prognostic score was simple and valuable for overall survival prediction.

Effect of 3D-printed hearts used in left ventricular outflow tract obstruction: a multicenter study

ObjectiveThe purpose of this research was to explore the application value of a three-dimensional (3D)-printed heart in surgery for left ventricular outflow tract (LVOT) obstruction.MethodsFrom August 2019 to October 2021, 46 patients with LVOT obstruction underwent surgical treatment at our institution. According to the treatment method, 22 and 24 patients were allocated to the experimental and control groups, respectively. In the experimental group, each patient’s 3D-printed heart model was used for simulated preoperative surgery, and then the Morrow operation was performed. In the control group, only the Morrow operation was performed, without simulated preoperative surgery using a 3D-printed heart model. The intraoperative and postoperative data of patients in the two groups were recorded, and the clinical data of patients were compared between the two groups.ResultsThe operation time, cardiopulmonary bypass time, intraoperative blood loss, hospitalization time, LVOT pressure difference (LVP), postoperative interventricular septal thickness (IST), aortic regurgitation (AR), systolic anterior motion (SAM), and postoperative left ventricular flow velocity (LVFV) were significantly lower in the experimental group than in the control group (P < 0.05). The inner diameter of the left ventricular outflow tract (IDLV) was larger in the experimental group than in the control group (P < 0.05). There was no significant difference in the postoperative ejection fraction, atrioventricular block rate or complication rate between the two groups (P > 0.05).ConclusionA 3D-printed heart model for simulated surgery in vitro is conducive to formulating a more reasonable surgical plan and reducing the trauma and duration of surgery, thereby promoting the recovery and maintenance of the heart.

Ivy sign: a diagnostic and prognostic biomarker for pediatric moyamoya.

Ivy sign is a radiographic finding on FLAIR MRI sequences and is associated with slow cortical blood flow in moyamoya. Limited data exist on the utility of the ivy sign as a diagnostic and prognostic tool in pediatric patients, particularly outside of Asian populations. The authors aimed to investigate a modified grading scale with which to characterize the prevalence and extent of the ivy sign in children with moyamoya and evaluate its efficacy as a biomarker in predicting postoperative outcomes, including stroke risk. Pre- and postoperative clinical and radiographic data of all pediatric patients (21 years of age or younger) who underwent surgery for moyamoya disease or moyamoya syndrome at two major tertiary referral centers in the US and Israel, between July 2009 and August 2019, were retrospectively reviewed. Ivy sign scores were correlated to Suzuki stage, Matsushima grade, and postoperative stroke rate to quantify the diagnostic and prognostic utility of ivy sign. A total of 171 hemispheres in 107 patients were included. The median age at the time of surgery was 9 years (range 3 months-21 years). The ivy sign was most frequently encountered in association with Suzuki stage III or IV disease in all vascular territories, including the anterior cerebral artery (53.7%), middle cerebral artery (56.3%), and posterior cerebral artery (47.5%) territories. Following surgical revascularization, 85% of hemispheres with Matsushima grade A demonstrated a concomitant, statistically significant reduction in ivy sign scores (OR 5.3, 95% CI 1.4-20.0; p = 0.013). Postoperatively, revascularized hemispheres that exhibited ivy sign score decreases had significantly lower rates of postoperative stroke (3.4%) compared with hemispheres that demonstrated no reversal of the ivy sign (16.1%) (OR 5.5, 95% CI 1.5-21.0; p = 0.008). This is the largest study to date that focuses on the role of the ivy sign in pediatric moyamoya. These data demonstrate that the ivy sign was present in approximately half the pediatric patients with moyamoya with Suzuki stage III or IV disease, when blood flow was most unstable. The authors found that reversal of the ivy sign provided both radiographic and clinical utility as a prognostic biomarker postoperatively, given the statistically significant association with both better Matsushima grades and a fivefold reduction in postoperative stroke rates. These findings can help inform clinical decision-making, and they have particular value in the pediatric population, as the ability to minimize additional radiographic evaluations and tailor radiographic surveillance is requisite.

The Effects of Thyroid Gland Volume and Weight on Surgical Approach Selection and Anesthesia Management in Retrosternal Goiter

Background: Retrosternal goiter surgery is a technically challenging procedure. Selecting the appropriate surgical approach is critical in preventing surgical and anesthesia complications. Objectives: This retrospective clinical study aimed to investigate the role of thyroid volume and weight in the development of retrosternal goiter and the importance of special anesthesia management in patients with retrosternal goiter, which is a potentially difficult airway candidate. Methods: Retrosternal goiter was detected in 125 patients through ultrasonography. Patients were divided into cervical surgery (CA) and sternotomy (ECA) groups. Volumetric measurements were performed ultrasonographically. Patients' demographics, preoperative thyroid ultrasonography features, American Society of Anesthesiologists (ASA) classifications, Mallampati classifications, intubation characteristics, perioperative and postoperative patient data, and postoperative thyroid specimen weights were recorded. Results: A total of 106 patients (32 male and 74 female) were operated on for bilateral total thyroidectomy. Total thyroidectomy was performed with CA in 98 (92.5%) patients and with ECA in 8 (7.5%) patients. Malignancy was detected in 4 (3%) of 106 operated cases. All of the malignant cases were seen in patients with a cervical approach. When the volumetric measurements of both groups were compared, the volume values were significantly higher in the ECA group (P=0.032). 67 patients were ASA I and 39 patients were ASA II. 64 patients were defined as Mallampati Class I, 36 patients as Mallampati Class II, and 6 patients as Mallampati Class III. Intubation was performed on the third attempt for 5 patients and 8 patients with Mallampati I and Mallampati II, respectively. The rate of difficult intubation was statistically significant in the ECA group (P=0.019). Conclusion: Predicting ECA requirement in the preoperative period is closely related to the preoperative volumetric analysis of the thyroid gland with three-dimensional ultrasonography. In addition, since anesthesia management is difficult in patients who need ECA, volumetric analysis has become even more critical.

Postoperative nonsteroidal anti-inflammatory drugs in relation to recurrence, survival and anastomotic leakage after surgery for colorectal cancer.

AimThe aim of this work was to investigate whether nonsteroidal anti‐inflammatory drugs (NSAIDs) could be beneficial or harmful when used perioperatively for colorectal cancer patients, as inflammation may affect occult disease and anastomotic healing.MethodThis is a protocol‐based retrospective cohort study on colorectal cancer patients operated on between 2007 and 2012 at 21 hospitals in Sweden. NSAID exposure was retrieved from postoperative analgesia protocols, while outcomes and patient data were retrieved from the Swedish Colorectal Cancer Registry. Older or severely comorbid patients, as well as those with disseminated or nonradically operated tumours were excluded. Multivariable regression with adjustment for confounders was performed, estimating hazard ratios (HRs) for long‐term outcomes and odds ratios (ORs) for short‐term outcomes, including 95% confidence intervals (CIs).ResultsSome 6945 patients remained after exclusion, of whom 3996 were treated at hospitals where a NSAID protocol was in place. No association was seen between NSAIDs and recurrence‐free survival (HR 0.97, 95% CI 0.87–1.09). However, a reduction in cancer recurrence was detected (HR 0.83, 95% CI 0.72–0.95), which remained significant when stratifying into locoregional (HR 0.68, 95% CI 0.48–0.97) and distant recurrences (HR 0.85, 95% CI 0.74–0.98). Anastomotic leakage was less frequent (HR 0.69%, 95% CI 0.51–0.94) in the NSAID‐exposed, mainly due to a risk reduction in colo‐rectal and ileo‐rectal anastomoses (HR 0.47, 95% CI 0.33–0.68).ConclusionThere was no association between NSAID exposure and recurrence‐free survival, but an association with reduced cancer recurrence and the rate of anastomotic leakage was detected, which may depend on tumour site and anastomotic location.

Abstract TMP80: Intraoperative Blood Flow Changes Predict Angiographic Outcomes After Direct Cerebral Revascularization For Moyamoya Disease

Introduction: Moyamoya Disease (MMD) is a progressive steno-occlusive vasculopathy of the large intracranial vessels precipitating ischemic and hemorrhagic events. Cerebral revascularization is the mainstay of treatment in MMD. Intraoperative measurements of cerebral blood flow following direct intracranial bypass may be performed to quantitatively assess the anastomosis. Objectives: To correlate intraoperative flow parameters in direct cerebral bypass for moyamoya disease to postoperative angiographic and clinical outcomes. Methods: Consecutive patients undergoing direct superficial temporal artery (STA) to middle cerebral artery (MCA) bypass were retrospectively analyzed. Preoperative and 6-month postoperative patient data was collected including presenting symptoms, MRI and angiographic findings, neurological complications, and functional outcome. Intraoperative cerebral blood flow was measured from the donor and recipient arteries using a micro flow probe pre- and post-anastomosis. Results: A total of 50 direct revascularization procedures in 39 patients were analyzed, of which 40 were in females (80%). The mean flow prior to anastomosis in the M4 MCA was +2.2 ± 6.1 ml/minute and +26.8 ± 19.0 ml/min in the STA. Post-anastomosis, the mean flow was -10.9 ± 14.8 ml/min (towards the Sylvian Fissure) in the proximal M4 and +7.9 ± 9.2 ml/min in the distal M4. At 6-month follow-up angiography, the graft was patent in all cases, with 98% demonstrating direct supply. A component of indirect supply was observed in 56% of grafts. Matsushima grade A, B, and C revascularization were obtained in 64%, 20%, and 16% of cases, respectively. Amongst Matsushima grade A patients, low flow was observed in the M4 (mean 1.7 ± 4.8 ml/min) prior to bypass, which became retrograde following bypass, measuring -13.5 ± 16.0 ml/min. Lower post bypass flow was observed in grade B and C patients, with -6.8 ± 13.1 ml/min and -5.6 ± 10.3 ml/min, respectively. Postoperative stroke occurred in one patient, who had a Matsushima grade C. Conclusions: Greater intraoperative retrograde flow in the recipient MCA immediately following anastomosis was observed in patients achieving a higher Matsushima grade.

Prediction of the transsphenoidal endoscopic adenomectomy results in patients with cushing’s disease

Introduction. Transsphenoidal adenomectomy (TSA) is the method of choice in the treatment of Cushing’s disease (CD), but remission of hypercorticism cannot be achieved in all patients. The search for predictors of CD remission after TSA remains to be an important challenge in the endocrinology today.Aim. To study the preoperative and postoperative data of patients with CD to identify the predictors of hypercorticism remission after TSA.Materials and methods. 101 patients with confirmed CD after TSA were included. One year after operation all patients were examined for the presence of hypercorticism remission and divided into two groups: with CD remission and its absence. In both groups’ preoperative pituitary magnetic resonance imaging (MRI) data, the results of preoperative high dose dexamethasone suppression test (HDDST) and the results of serum cortisol collected in the morning 2–3 days after surgery were compared.Results. One year after TSA, CD remission was confirmed in 63 patients (62.4%), whereas in 38 patients (37.6%) hypercortisolism persisted. Favorable predictors of CD remission were: the adenoma size &gt; 3 mm without the invasive growth according to pituitary MRI (specificity 82.4%, sensitivity 82.8%), serum cortisol suppression ≥ 74% in preoperative HDDST (specificity 81.5%, sensitivity 86.3%), morning serum cortisol level in 2–3 days after surgery ≤ 388 nmol/l (specificity 79.3%, sensitivity 97.4%).Conclusions. Pituitary MRI data, the results of preoperative HDDST and morning serum cortisol in the 2–3 days after surgery can be used as predictors of CD remission.

Surgical Outcomes of Vaginal or Cervical Melanoma.

Objective: To evaluate the effectiveness of radical resection compared with non-radical resection for vaginal or cervical melanoma.Methods: We retrospectively analysed the clinical data of post-operative patients with primary lower genital tract melanoma hospitalised at Peking University Cancer Hospital between Jan 2014 and Dec 2020. The study endpoints were recurrence-free survival (RFS) and overall survival (OS). Kaplan–Meier method-plotted survival curves and univariate and multivariate Cox proportional hazards regression models were used to identify the factors associated with RFS and OS, and to calculate hazard ratios (HRs) and associated 95% confidence intervals (95% CIs).Results: A total of 80 patients were included. Thirty-one patients had received non-radical resection, and 49 patients had received radical resection. The median patient age was 55.5 (IQR 45.3–60.0) years. Sixty-two (77.5%) patients had vaginal melanoma. Sixty-four patients (80.0%) had received post-operative adjuvant therapy. The median follow-up time was 36.0 months (95% CI 10.1–62.1 months). Sixty-four patients developed recurrence, and 44 patients died. The median RFS (mRFS) was 6.0 months (95% CI 3.4–8.6 m), and the RFS for the radical resection group was longer than that for the non-radical resection group (9.5 vs. 5.3 m), with no significant difference (P > 0.05). The median OS (mOS) was 25.9 months (95% CI 14.4–37.4 m). The mOS was 24.6 months (95% CI 10.3–38.9 m) and 25.9 months (95% CI 10.9–40.9 m) in the non-radical resection group and the radical resection group, respectively. Multivariate Cox regression analysis showed that surgical approach, infiltration depth of the tumour, lymph node metastasis, and post-operative adjuvant therapy were independent risk factors for RFS and that post-operative adjuvant therapy was an independent risk factor for OS.Conclusion: By performing multivariate analysis, which corrected for potential confounding factors, we identified surgical procedures that were associated with RFS, and we found that RFS and OS in patients with vaginal melanoma and cervical melanoma benefitted from post-operative adjuvant therapy.

Early warning model of recurrence site for breast cancer rehabilitation patients based on adaptive mesh optimization XGBoost

Objective: Breast cancer is a malignant disease with a high mortality rate. Using postoperative rehabilitation data of breast cancer patients, this study explored the effects of immune, tumor, microenvironmental, psychological, nutritional, aerobic exercise and advanced work indexes on the rehabilitation of breast cancer patients. To determine the weight of the impact of different indications on cancer recovery. By combining the adaptive grid optimization algorithm with the XGBoost (Extreme Gradient Boosting) algorithm, an intelligent prediction model for breast cancer rehabilitation was constructed using patients indexes as input and the recurrence location as the output. Our results showed that the model constructed in this study could effectively predict cancer cell metastasis during breast cancer recurrence in recovered patients. Compared with artificial intelligence algorithm models such as neural network algorithm, support vector machine algorithm, gradient boosting tree algorithm and Adaboost, the model demonstrated a forecast accuracy rate of &gt;93%. The model established in this study could effectively predict the recurrence position of breast cancer and provide an auxiliary reference for doctors to treat breast cancer patients more effectively.

Pure vs Pancreatic Fistula-Associated Biliary Leak after Pancreaticoduodenectomy: Different Twins

Introduction: Biliary leak (BL) after pancreatoduodenectomy (PD) is a rare complication, with variable severity. We sought to evaluate the range of possible treatment strategies and outcomes for BL, according to the presence of an associated postoperative pancreatic fistula (POPF). Methods: Postoperative data of patients undergoing PD at the Verona and the Karolinska University Hospitals between 2011 and 2020 were retrospectively reviewed, including: BL incidence, grading and outcomes; BL time of onset and resolution; the presence of associated postoperative pancreatic fistula (POPF); BL-specific treatments and their timing. Results: A BL occurred in 153 out of 2715 patients undergoing PD (6%). Ten patients with BL were excluded due to missing postoperative data. Of the remaining 143, 67 (47%) had an associated POPF (POPF-BL) while 76 (53%) had a pure BL. Pancreas-specific morbidity and in-hospital mortality (19% vs 4%; P< 0.01) were higher in the POPF-BL group. Time of BL onset was similar between the groups, while BL closure occurred earlier in pure BL (12 vs 23 days; P< 0.01). Conservative treatment was more frequent in the pure BL group (55 vs 15%; P< 0.01), while the rate of percutaneous and/or trans-hepatic drain placement was similar. Relaparotomy was more common in the POPF-BL group (42% VS 17%; P< 0.01) but occurred earlier in case of pure BL (2 vs 10 days; P= 0.02). Conclusions: The association with POPF is a negative prognostic factor for BL after PD. Pure BL represents a more benign entity, which is managed conservatively in half of the cases.

The Implementation of Modified ERAS Protocol in Laparoscopic Radical Cystectomy: An Outcome at Universitas Gadjah Mada Urological Institute

Background: Enhanced recovery after surgery (ERAS) protocol is multimodal perioperative care designed to achieve enhanced postoperative outcomes. Unfortunately, all these elements are not always fully applied due to each center’s limitations. In this study, the ERAS protocol was modified and implemented in patients with bladder cancer who underwent laparoscopic radical cystectomy (LRC). This study aimed to evaluate the outcomes of the modified ERAS protocol in LRC surgery. Methods: The retrospective study design was used to evaluate 35 patients (27 males and 8 females) who underwent LRC with the application of the perioperative modified ERAS protocol. All information relating to perioperative, intraoperative, and postoperative patient data was obtained from medical records. All complications that occurred were classified according to the Clavien-Dindo classification.Results: The mean age in this study was 58.3 ± 9.2, and the most common pathological finding was urothelial carcinoma. Intraoperative blood loss was 318.5 ± 112.5 cc with those requiring intraoperative blood transfusion of 4.8 ± 2.0 patients. The mean first diet was 2.1 ± 1.2 days. For bowel activities, the first flatulence was 1.6 ± 0.8 days. The mean mobilization with first sitting was 1.8 ± 0.9 days. Seventeen percent of patients experienced intraoperative complications and postoperative complications were encountered in 28.6% of patients. According to the ClavienDindo classification, most complications were grades 1-2 (17.1%). There was no incidence of mortality in this study.Conclusions: These promising results, including the postoperative recovery and complications rates, require validation with multi-center and randomized studies to confirm the benefits of the modified ERAS protocol in minimally invasive procedures, especially LRC surgery

Younger age is a significant factor for poorer adherence in fracture patients who received low-intensity pulsed ultrasound: A retrospective study

BackgroundThe factors for poor adherence to therapy in patients with postoperative fracture who are treated with low-intensity pulsed ultrasound remain unknown. Therefore, we designed a retrospective cohort study to determine the various factors for poorer adherence to therapy in patients with postoperative fracture who were treated with low-intensity pulsed ultrasound therapy. MethodsWe retrospectively analyzed the data of postoperative patients who underwent low-intensity pulsed ultrasound after fracture surgery from January 2010 to May 2019. The patients were categorized into two groups as follows: group G, including those with a good adherence rate (>72%), and group P, including those with a poor adherence rate (<72%). Factors, such as age, sex, how the rental cost of low-intensity pulsed ultrasound was paid (by the patients themselves or by the insurance company), living (alone or with someone), insurance claim item (fractures within 3 weeks after osteosynthesis or delayed or non-union fractures), low-intensity pulsed ultrasound device-type (earlier- or next-generation), duration of low-intensity pulsed ultrasound use, fracture site (upper or lower limb), frequency of hospital visits (regular or irregular), and employment status (employed/unemployed) were compared between groups G and P. ResultsIn total, 96 patients (74 and 22 patients in groups G and P, respectively) who underwent low-intensity pulsed ultrasound were included in the study. Univariate analysis revealed that younger patients (P < 0.001) and patients who did not regularly visit the hospital (P = 0.024) were more likely to have poorer adherence to therapy. Multiple logistic regression analysis revealed that age was the only independent, pertinent factor for poorer adherence to therapy (odds ratio, 8.570; 95% confidence interval, 2.770–26.50; P < 0.001), with a cutoff value of 41 years. ConclusionsYounger age is a significant factor for poorer adherence in patients undergoing low-intensity pulsed ultrasound therapy.
