RESUMEN

BACKGROUND: Cancer susceptibility germline mutations are associated with pancreatic ductal adenocarcinoma (PDAC). However, the hereditary status of PDAC and its impact on survival is largely unknown in the Asian population. METHODS: Exome sequencing was performed on 527 blood samples from PDAC individuals and analyzed for mutations in 80 oncogenic genes. Pathogenic and likely pathogenic (P/LP) germline variants were diagnosed according to the ACMG variant classification categories. The association between germline homologous recombination gene mutations (gHRmut, including BAP1, BRCA1, BRCA2, PALB2, ATM, BLM, BRIP1, CHEK2, NBN, MUTYH, FANCA and FANCC) and the treatment outcomes was explored in patients with stage III/IV diseases treated with first-line (1L) platinum-based versus platinum-free chemotherapy. RESULTS: Overall, 104 of 527 (19.7%) patients carried germline P/LP variants. The most common mutated genes were BRCA2 (3.60%), followed by ATR (2.66%) and ATM (1.9%). After a median follow-up duration of 38.3-months (95% confidence interval, 95% CI 35.0-43.7), the median overall survival (OS) was not significantly different among patients with gHRmut, non-HR germline mutations, or no mutation (P = 0.43). Among the 320 patients with stage III/IV disease who received 1L combination chemotherapy, 32 (10%) had gHRmut. Of them, patients receiving 1L platinum-based chemotherapy exhibited a significantly longer median OS compared to those with platinum-free chemotherapy, 26.1 months (95% CI 12.7-33.7) versus 9.6 months (95% CI 5.9-17.6), P = 0.001. However, the median OS of patients without gHRmut was 14.5 months (95% CI 13.2-16.9) and 12.6 months (95% CI 10.8-14.7) for patients receiving 1L platinum-based and platinum-free chemotherapy, respectively (P = 0.22). These results were consistent after adjusting for potential confounding factors including age, tumor stage, performance status, and baseline CA 19.9 in the multivariate Cox regression analysis. CONCLUSIONS: Our study showed that nearly 20% of Taiwanese PDAC patients carried germline P/LP variants. The longer survival observed in gHRmut patients treated with 1L platinum-based chemotherapy highlights the importance of germline testing for all patients with advanced PDAC at diagnosis.

RESUMEN

BACKGROUND/PURPOSE: Encapsulating peritoneal sclerosis (EPS) is a rare and potential lethal complication of peritoneal dialysis characterized by bowel obstruction. Surgical enterolysis is the only curative therapy. Currently, there are no tools for predicting postsurgical prognosis. This study aimed to identify a computed tomography (CT) scoring system that could predict mortality after surgery in patients with severe EPS. METHODS: This retrospective study enrolled patients with severe EPS who underwent surgical enterolysis in a tertiary referral medical center. The association of CT score with surgical outcomes including mortality, blood loss, and bowel perforation was analyzed. RESULTS: Thirty-four patients who underwent 37 procedures were recruited and divided into a survivor and non-survivor group. The survivor group had higher body mass indices (BMIs, 18.1 vs. 16.7 kg/m2, p = 0.035) and lower CT scores (11 vs. 17, p < 0.001) than the non-survivor group. The receiver operating characteristic curve revealed that a CT score of ≥15 could be considered a cutoff point to predict surgical mortality, with an area under the curve of 0.93, sensitivity of 88.9%, and specificity of 82.1%. Compared with the group with CT scores of <15, the group with CT scores of ≥15 had a lower BMI (19.7 vs. 16.2 kg/m2, p = 0.004), higher mortality (4.2% vs. 61.5%, p < 0.001), greater blood loss (50 vs. 400 mL, p = 0.007), and higher incidence of bowel perforation (12.5% vs. 61.5%, p = 0.006). CONCLUSION: The CT scoring system could be useful in predicting surgical risk in patients with severe EPS receiving enterolysis.

RESUMEN

BACKGROUND: Obesity increases surgical risks in various abdominal surgeries and its impact on open pancreaticoduodenectomy (OPD) and minimally invasive pancreaticoduodenectomy (MIPD) remains unknown. This study aimed to compare the surgical outcomes of OPD and MIPD in obese and non-obese patients by propensity score matching (PSM) analysis during the implementation of MIPD. METHODS: We retrospectively reviewed all pancreaticoduodenectomies from December 2014 to May 2021. Obesity was defined as body mass index > 25 kg/m2 according to World Health Organization International Obesity Task Force. PSM was used to minimize the selection bias of MIPD. RESULTS: Among 462 pancreaticoduodenectomies (339 OPDs, 123 MIPDs), there were 313 patients in the non-obese group (MIPD: 78, OPD: 235) and 149 patients in the obese group (MIPD: 45, OPD: 104). After PSM, there were 70 MIPD/106 OPD patients in the non-obese group and 38 MIPD/54 OPD patients in the obese group. The obese MIPD patients had more fluid collection (36.8% vs 9.8%, p = 0.002), a higher Clavien-Dindo (CD) grade (p = 0.007), more major complications (42.1% vs 14.8%, p = 0.004), and longer operative times (306 min vs 264 min, p < 0.001) than the obese OPD patients. The non-obese MIPD patients had lower CD grades (p = 0.02), longer operative times (294 vs 264 min, p < 0.001), and less blood loss (100 mL vs 200 mL) than the non-obese OPD patients. MIPD was a strong predictor of major complication (CD ≥ 3) in obese patients (odds ratio 3.11, 95% CI: 1.40-6.95, p = 0.005). CONCLUSIONS: Minimally invasive approaches deteriorate the CD grade, fluid collection, and major complications in obese patients undergoing pancreaticoduodenectomy during the initial development period. Non-obese patients may benefit from MIPD over OPD in terms of less blood loss and lower CD grades. The impact of BMI on MIPD should be considered when assessing the surgical risks.

RESUMEN

BACKGROUND: Sorafenib (SOR) is the first line treatment for advanced hepatocellular carcinoma (HCC), but resistance develops frequently. Tumor-associated macrophages (TAMs) have been reported to affect the progression of HCC. We therefore aimed to study the role of TAMs in promoting SOR resistance. METHODS: Immunofluorescence staining for the M2 marker CD204 and the cancer stem cell (CSC) markers CD44 and CD133 was performed in paired HCC and adjacent noncancerous tissues and HCC tissues stratified by response of SOR treatment. HCC/U937 coculture system and cytokines were used to induce M2 polarization for studying the effects of M2 TAMs on CSC properties and apoptotic death of HCC cells after SOR treatment. RESULTS: Higher expression of CD204, CD44, and CD133 was observed in patients with SOR nonresponse (SNR) than in those with SOR response (SR), suggesting that SNR is positively correlated to levels of CSCs and M2 TAMs. After coculture, M2 TAMs could increase the level of CSCs but decrease SOR-induced apoptosis. Incubation of HCC cells with coculture conditioned medium increased the formation of spheres that were resistant to SOR. Furthermore, CXCL1 and CXCL2 were found to be the potential paracrine factors released by M2 TAMs to upregulate SOR resistance in HCC cells. Treatment with CXCL1 and CXCL2 could increase HCC CSC activity but decrease SOR-induced apoptosis by affecting BCL-2 family gene expression. Using pharmacological inhibitors, CXCR2/ERK signaling was found to be critical to CXCL1- and CXCL2-mediated SOR resistance. CONCLUSION: This study identified CXCL1, CXCL2, and their downstream CXCR2/ERK signaling as potential therapeutic targets to overcome SOR resistance in HCC.

RESUMEN

BACKGROUND: Undertriage of major trauma patients is unavoidable, especially in the trauma system of rural areas. Timely stabilization and transfer of critical trauma patients remains a great challenge for hospitals with limited resources. No definitive measure has been proven to improve the outcomes of patients transferred with major trauma. The current study hypothesized that regular feedback on inter-hospital transfer of patients with major trauma can improve quality of care and clinical outcomes. METHOD: This retrospective cohort study retrieved data of transferred major trauma patients with an injury severity score (ISS) > 15 between January 2010 and December 2018 from the trauma registry databank of a tertiary medical center. Regular monthly feedback on inter-hospital transfers was initiated in 2014. The patients were divided into a without-feedback group and a with-feedback group. Demographic data, management before transfer, and outcomes after transfer were collected and analyzed. RESULTS: A total of 178 patients were included: 69 patients in the without-feedback group and 109 in the with-feedback group. The with-feedback group had a higher ISS (25 vs. 27; p = 0.049), more patients requiring massive transfusion (14.49% vs. 29.36%, p = 0.036), and less patients with Glasgow Coma Scale ≤8 (30.43% vs. 23.85%, p <  0.001). After adjusting for confounding factors, the with-feedback group was associated with a higher rate of blood transfusion before transfer (adjusted odds ratio [aOR]: 2.75; 95% confidence interval [CI]: 1.01-7.52; p = 0.049), shorter time span before blood transfusion (- 31.80 ± 15.14; p = 0.038), and marginally decreased mortality risk (aOR: 0.43; 95% CI: 0.17-1.09; p = 0.076). CONCLUSION: This study revealed that regular feedback on inter-hospital transfer improved the quality of blood transfusion.

RESUMEN

BACKGROUND: Trauma is one of the leading causes of death in Taiwan, and its medical expenditure escalated drastically. This study aimed to explore the effectiveness of trauma team, which was established in September 2010, on medical resource utilization and quality of care among major trauma patients. METHODS: This was a retrospective study, using trauma registry data bank and inpatient medical service charge databases. Study subjects were major trauma patients admitted to a medical center in Tainan during 2009 and 2013, and was divided into case group (from January, 2011 to August, 2013) and comparison group (from January, 2009 to August, 2010). RESULTS: Significant reductions in several items of medical resource utilization were identified after the establishment of trauma team. In the sub-group of patients who survived to discharge, examination, radiology and operation charges declined significantly. The radiation and examination charges reduced significantly in the subcategories of ISS = 16 ~ 24 and ISS > 24 respectively. However, no significant effectiveness on quality of care was identified. CONCLUSIONS: The establishment of trauma team is effective in containing medical resource utilization. In order to verify the effectiveness on quality of care, extended time frame and extra study subjects are needed.

RESUMEN

BACKGROUND: Osteopontin (OPN) can recruit macrophages to the site of inflammation and promote tumorigenesis. M2 tumor-associated macrophages (M2-TAMs) also play an important role in cancer progression. This study aimed to clarify the role of OPN and M2-TAMs co-existence in gastric cancer. METHODS: The levels of OPN and M2-TAMs were evaluated by immunohistochemical staining in 170 resected gastric cancer specimens that were collected from 1998 to 2012. M2-TAMs were identified by staining for an M2 marker, CD204. The prognostic significance and correlation between OPN and CD204 expression were analyzed. A co-culture system of OPN+-AGS and U937 cells was designed to study the effect of OPN on the skewing of macrophages toward M2-TAMs for gastric cancer progression in vitro and in vivo. RESULTS: Patients with high expression (>50%) of OPN or CD204 exhibited poor 5-year overall survival rates (48.61%, p = 0.0055, and 52.14%, p = 0.0498, respectively). A positive correlation was observed between OPN and CD204 expression and high co-expression of OPN and CD204 demonstrated poor 5-year overall survival rates (48.90%, p = 0.0131). In the co-culture study, OPN was able to attract U937 cells and skew them toward M2-TAMs through paracrine action. The M2-TAMs could increase the invasiveness of OPN+-AGS cells and the growth rate of xenograft of a mixture of co-cultured OPN+-AGS and U937 cells. CONCLUSION: OPN can skew macrophages toward M2-TAMs during gastric cancer progression. The co-existence of OPN and infiltrating M2-TAMs correlates with disease progression and poor survival and thus can serve as a prognostic marker in gastric cancer.

RESUMEN

The present systematic review and meta-analysis aimed to compare long-term survival after proximal gastrectomy (PG) and total gastrectomy (TG) for locally advanced proximal gastric cancer (GC). The PubMed, EMBASE and Cochrane CENTRAL databases were searched from their inception to May 2023. Only published two-arm prospective or retrospective studies were included. The selected studies included patients with locally advanced GC who underwent PG or TG and reported quantitative survival outcomes. The primary outcome was overall survival (OS) after gastrectomy. Three studies involving a total of 4,815 patients met the inclusion criteria. The age of the patients ranged from 57.03-64.46 years and 78.80% were male. The estimated 5-year OS probability after TG varied from 30.14 to 72.0%, and from 42.06 to 74.9% after PG. Results of the meta-analyses revealed a significant association between PG and improved OS compared with that of TG, with a pooled hazard ratio of 1.15 (95% CI, 1.05-1.25). No heterogeneity was observed in the included studies (I2=0%). Overall, in managing locally advanced GC, PG demonstrated comparable or marginally improved OS compared with TG during postoperative follow-up; however, further meta-analyses are required to provide stronger evidence.

RESUMEN

BACKGROUND: Suturing is a crucial clinical skill for nurse practitioners (NPs), but the effectiveness of traditional training methods (e.g., physical suture kits combined with video content) is low. OBJECTIVE: This study compared the effectiveness and usability of a mobile-based web app (MoWa) developed for NPs to learn simple suturing skills with those of traditional instructional video-based training. METHODS: The MoWa system utilizes mobile devices to simulate hands-on suturing and provides learning guidance and feedback to support self-learning with a physical suturing kit. Fifty-four suturing novices (NPs) were recruited as participants, divided into an experimental group (EG: 28 participants) and a control group (CG: 26 participants), and instructed to self-learn for 3 weeks. Learning effectiveness and system usability were evaluated through a pretest and posttest. RESULTS: The EG exhibited significant improvements in learning outcomes, self-confidence, self-efficacy, and learning anxiety and expressed satisfaction with the MoWa system. Furthermore, the EG also considerably enhanced learning outcomes, self-efficacy, and learning anxiety compared to the CG, with no significant difference in self-confidence. CONCLUSION: The MoWa system combined with deliberate practice is an effective strategy for supporting suturing skills training.

RESUMEN

High-grade liver laceration is a common injury with bleeding as the main cause of death. Timely resuscitation and hemostasis are keys to the successful management. The impact of in-hospital trauma system on the quality of resuscitation and management in patients with traumatic high-grade liver laceration, however, was rarely reported. We retrospectively reviewed the impact of team-based approach on the quality and outcomes of high-grade traumatic liver laceration in our hospital. Patients with traumatic liver laceration between 2002 and 2020 were enrolled in this retrospective study. Inverse probability of treatment weighting (IPTW)-adjusted analysis using the propensity score were performed. Outcomes before the trauma team establishment (PTTE) and after the trauma team establishment (TTE) were compared. A total of 270 patients with liver trauma were included. After IPTW adjustment, interval between emergency department arrival and managements was shortened in the TTE group with a median of 11 min (p < 0.001) and 28 min (p < 0.001) in blood test reports and duration to CT scan, respectively. Duration to hemostatic treatments in the TTE group was also shorter by a median of 94 min in patients receiving embolization (p = 0.012) and 50 min in those undergoing surgery (p = 0.021). The TTE group had longer ICU-free days to day 28 (0.0 vs. 19.0 days, p = 0.010). In our study, trauma team approach had a survival benefit for traumatic high-grade liver injury patients with 65% reduction of risk of death within 72 h (Odds ratio (OR) = 0.35, 95% CI = 0.14-0.86) and 55% reduction of risk of in-hospital mortality (OR = 0.45, 95% CI = 0.23-0.87). A team-based approach might contribute to the survival benefit in patients with traumatic high-grade liver laceration by facilitating patient transfer from outside the hospital, through the diagnostic examination, and to the definitive hemostatic procedures.

RESUMEN

BACKGROUND: Upfront resection (UR) followed by adjuvant chemotherapy remains the standard treatment for resectable pancreatic cancer. There is increasing evidence suggesting favourable outcomes toward neoadjuvant chemotherapy (NAC) followed by surgery. METHODS: All clinical staging with resectable pancreatic cancer patients treated at a tertiary medical centre from 2013 to 2020 were identified. The baseline characteristics, treatment course, surgery outcome and survival results of UR or NAC were compared. RESULTS: Finally, in 159 resectable patients, 46 patients (29%) underwent NAC and 113 patients (71%) received UR. In NAC, 11 patients (24%) did not receive resection, 4 (36.4%) for comorbidity, 2 (18.2%) for patient refusal and 2 (18.2%) for disease progression. In UR, 13 patients (12%) were unresectable intraoperatively; 6 (46.2%) for locally advanced and 5 (38.5%) for distant metastasis. Overall, 97% of patients in NAC and 58% of patients in UR completed adjuvant chemotherapy. As of data cut-off, 24 patients (69%) in NAC and 42 patients (29%) in UR were still tumour free. The median recurrence-free survival in NAC, UR with adjuvant chemotherapy and without adjuvant chemotherapy were 31.3 months (95% CI, 14.4-not estimable), 10.6 months (95% CI, 9.0-14.3) and 8.5 months (95% CI, 5.8-11.8), P =0.036; and the median overall survival in each group were not reached (95% CI, 29.7-not estimable), 25.9 months (95% CI, 21.1-40.5) and 21.7 months (12.0-32.8), P =0.0053. Based on initial clinical staging, the median overall survival of NAC was not significantly different from UR with a tumour less than or equal to 2 cm, P =0.29. NAC patients had a higher R0 resection rate (83% versus 53%), lower recurrence rate (31% versus 71%) and harvested median number lymph node (23 versus 15). CONCLUSION: This study demonstrates that NAC is superior to UR in resectable pancreatic cancer with better survival.

RESUMEN

INTRODUCTION: Early definite treatment for orthopedic patients is strongly advocated. However, a consensus has not been reached on the optimal timing of long bone fracture fixation for patients with associated mild traumatic brain injury (TBI). Surgeons lack evidence on the basis on which they should decide on the operation timing. METHODS: We retrospectively reviewed the data of patients with mild TBI and lower extremity long bone fractures from 2010 to 2020. The patients receiving internal fixation within and after 24 h were defined as the early- and delayed-fixation groups. We compared the discharge Glasgow Coma Scale (GCS) scores, lengths of stay, and in-hospital complications. Propensity score matching (PSM) with multiple adjusted variables and a 1:1 matching ratio was applied to reduce selection bias. RESULTS: In total, 181 patients were enrolled; 78 (43.1%) and 103 (56.9%) patients received early and delayed fracture fixation, respectively. After matching, each group had 61 participants and were statistically identical. The delayed group did not have better discharge GCS scores (early vs. delayed: 15.0 ± 0 vs. 15.0 ± 0.1; p = 0.158). The groups did not differ in their lengths of hospital stay (15.3 ± 10.6 vs. 14.8 ± 7.9; p = 0.789), intensive care unit stay (2.7 ± 4.3 vs. 2.7 ± 3.8; p = 0.947), or incidence of complications (23.0% vs. 16.4%; p = 0.494). CONCLUSIONS: Delayed fixation for patients with lower extremity long bone fractures concurrent with mild TBI does not result in fewer complications or improved neurologic outcomes compared with early fixation. Delaying fixation may not be necessary to prevent the second hit phenomenon and has not demonstrated any clear benefits.

RESUMEN

Laparoscopic (LPD) and robotic pancreaticoduodenectomy (RPD) are both challenging procedures. The feasibility and safety of simultaneously developing LPD and RPD remain unreported. We retrospectively reviewed the data of patients undergoing LPD or RPD between 2014 and 2021. A total of 114 patients underwent minimally invasive pancreaticoduodenectomy (MIPD): 39 LPDs and 75 RPDs. The learning process of LPD and RPD were similar. The cutoff points of the learning curve were LPD, 13th patient (the 27th patient of MIPD), and RPD, 18th patient (the 31st patient of MIPD) according the cumulative sum analysis of operative time. A decrease in the operative time was associated with the case sequence (p < 0.001) but not with the surgical approach (p = 0.36). The overall surgical outcomes were comparable between both the LPD and RPD groups. When evaluating the learning curve impact on MIPD, LPD had higher major complication (≧ Clavien-Dindo grade III), bile leak and wound infection rates in the pre-learning curve phase than those in the after-learning curve phase, while RPD had similar surgical outcomes between two phases. Simultaneous development of LPD and RPD is feasible and safe for experienced surgeons, with similar learning process and comparable surgical outcomes.

RESUMEN

BACKGROUND: The aim of this study is to design a simple, secure, and safe technique of intracorporeal Pringle's maneuver to facilitate safer laparoscopic liver resection. METHODS: A self-designed six-loop catheter was made using 20-French T-tube and 10-French nelaton urethral catheter. The cross head and stem of the T-tube were trimmed to 1 cm, respectively. The nelaton was shortened to 12-cm-long tube from the round tip, and the cut end was inserted and sutured to the stem of the T-tube. After establishment of pneumoperitoneum, the T-tube with nelaton was placed into the abdomen. The round end of the nelaton was inserted into the lesser sac and pulled through the foramen of Winslow, and the end of nelaton was then inserted into one end of the T-tube and pulled through the other end, forming a six-loop. The nelaton was pulled to occlude the hepatic inflow and temporarily fixed with 1-0 Vicryl on a curved round needle on the other end of the T-tube. The protocol of Pringle's maneuver was 15-min clamp and 5-min release periods. The liver parenchymal transection was performed using Harmonic scalpel. RESULTS: From November 2009 to August 2011, 20 patients received laparoscopic liver resection using the six-loop Pringle's maneuver. During operation, 17 patients were positioned supine, 2 patients in left decubitus, and 1 patient in supine followed by left decubitus position. There were 9 anatomical resections and 11 nonanatomical resections (18 patients for single lesion, 1 for two lesions, and 1 for three lesions). The average times of liver resection and Pringle's maneuver were 33.1 and 36.2 min, respectively. Mean blood loss was 102.5 ml. The postoperative course was uneventful, and average hospital stay was 4.4 days. CONCLUSION: Our self-designed six-loop intracorporeal Pringle's maneuver can facilitate safer laparoscopic liver resection.

RESUMEN

Riedel's thyroiditis, known as invasive fibrous thyroiditis, is a very rare form of chronic thyroiditis. It is hard to make the diagnosis without surgical biopsy. We present a case of Riedel's thyroiditis in a 52-year-old female with past history of Hashimoto's thyroiditis. She suffered from bilateral neck pain, which radiated to both lower jaws. The erythrocyte sedimentation rate was 125 mm/hour. Subacute thyroiditis superimposed on Hashimoto's thyroiditis was diagnosed and treated with steroid. However the response was poor and she had a history of severe peptic ulcer. To avoid inducing the peptic ulcer by steroid, she received bilateral subtotal thyroidectomy. During surgery, the thyroid had severe adhesion to surrounding soft tissue and the pathology showed Riedel's thyroiditis. The neck pain improved after thyroidectomy. Tamoxifen has been given for 8 months and the size of remnant thyroid decreased to 8 mm. We concluded that combined thyroidectomy and tamoxifen successfully cured a patient with Riedel's thyroiditis.

RESUMEN

BACKGROUND: Maxillofacial fractures can lead to massive oronasal bleeding; however, surgical hemostasis and packing procedures can be challenging owing to complex facial anatomy. Only a few studies investigated maxillofacial fractures with massive oronasal hemorrhage. However, thus far, no studies have reported a protocolized management approach for maxillofacial trauma from a single center. This study aimed to evaluate the effectiveness of protocolized management for maxillofacial fractures with oronasal bleeding. METHODS: Patients were identified from the National Cheng University Hospital trauma registry from 2010 to 2020. We included patients with a face Abbreviated Injury Scale (AIS) score of > 3 and active oronasal bleeding. Patients' characteristics were compared between the angiography and non-angiography groups and between survivors and nonsurvivors. RESULTS: Forty-nine patients were included. Among them, 34 (69%) underwent angiography, of whom 21 received arterial embolization. Forty-seven patients (96%) successfully achieved hemostasis by adhering to the treatment protocol at our institution. Compared with the non-angiography group, the angiography group had significantly more patients requiring oral intubation (97% vs. 53%, P < 0.001), Glasgow Coma Scale < 9 (GCS; 79% vs. 27%, P < 0.001), head AIS > 3 (65% vs. 13%, P = 0.001), higher Injury Severity Score (ISS; 43 [33-50] vs. 22 [18-27], P < 0.001), higher incidence of cardiopulmonary resuscitation (CPR; 41% vs. 0%, P = 0.002), higher mortality rate (35% vs. 7%, P = 0.043), and more units of packed red blood cells (PRBC) transfused within 24 h (12 [6-20] vs. 2 [0-4], P < 0.001). The nonsurvivor group had significantly more patients with hypotension (62% vs. 8%; P < 0.001), higher need for CPR (85% vs. 8%; P < 0.001), head AIS > 3 (92% vs. 33%; P < 0.001), skull base fracture (100% vs. 64%; P = 0.011), GCS score < 9 (100% vs. 50%; P = 0.003), higher ISS (50 [43-57] vs. 29 [19-48]; P < 0.001), and more units of PRBC transfused within 24 h (18 [13-22] vs. 6 [2-12]; P = 0.001) than the survivor group. More patients underwent angiography in the nonsurvivor group than in the survivor group (92% vs. 61%; P = 0.043). Among embolized vessels, the internal maxillary artery (65%) was the most common bleeding site. Hypoxic encephalopathy accounted for 92% of deaths. CONCLUSIONS: Protocol-guided management effectively optimizes outcomes in patients with maxillofacial bleeding.

RESUMEN

BACKGROUND: Patients sustaining multiple rib fractures have a significant risk of developing morbidity and mortality. More evidence is emerging that the indication of surgical stabilization of rib fractures (SSRF) should expand beyond flail chest. Nevertheless, little is known about factors associated with poor outcomes after surgical fixation. We reviewed patients with rib fractures to further explore the role of SSRF; we matched two groups by propensity score (PS). METHOD: A comparison of patients with blunt thoracic trauma treated with SSRF between 2010 and 2020 was compared with those who received conservative treatment for rib fractures. Risk factors for poor outcomes were analyzed by multivariate regression analysis. RESULTS: After tailored SSRF, the number of fractured ribs was not associated with longer ventilator days (p = 0.617), ICU stay (p = 0.478), hospital stay (p = 0.706), and increased nonprocedure-related pulmonary complications (NPRCs) (p = 0.226) despite having experienced much more severe trauma. In the multivariate regression models, lower GCS, delayed surgery, thoracotomy, and flail chest requiring mechanical ventilation were factors associated with prolonged ventilator days. Lower GCS, higher ISS, delayed surgery, and flail chest requiring mechanical ventilation were factors associated with longer ICU stays. Lower GCS and older age were factors associated with increased NPRCs. In the PS model, NPRCs risk was reduced by SSRF. CONCLUSIONS: The risk of NPRCs was reduced once ribs were surgically fixed through an algorithmic approach, and poor consciousness and aging were independent risk factors for NPRCs.

RESUMEN

Delayed bleeding is a major issue in patients with high-grade splenic injuries who receive non-operative management (NOM). While only few studies addressed the clinical manifestations of delayed bleeding in these patients. We reviewed the patients with high-grade splenic injuries presented with delayed bleeding, defined as the need for salvage procedures following NOM. There were 138 patients received NOM in study period. Fourteen of 107 patients in the SAE group and 3 of 31 patients in the non-embolization group had delayed bleeding. Among the 17 delayed bleeding episodes, 6 and 11 patients were salvaged by splenectomy and SAE, respectively. Ten (58.9%, 10/17) patients experienced bleeding episodes in the intensive care unit (ICU), whereas seven (41.1%, 7/17) experienced those in the ward or at home. The clinical manifestations of delayed bleeding were a decline in haemoglobin levels (47.1%, 8/17), hypotension (35.3%, 6/17), tachycardia (47.1%, 8/17), new abdominal pain (29.4%, 5/17), and worsening abdominal pain (17.6%, 3/17). For the bleeding episodes detected in the ICU, a decline in haemoglobin (60%, 6/10) was the main manifestation. New abdominal pain (71.43%, 5/7) was the main presentation when the patients left the ICU. In conclusion, abdominal pain was the main early clinical presentation of delayed bleeding following discharge from the ICU or hospital.

RESUMEN

Pancreatic cancer (PC) has the highest frequency of developing cancer cachexia (CC)-sarcopenia (SC) syndrome, which negatively influences patients' outcome, quality of life, and tolerance/response to treatments. However, the clinical impacts of CC, SC, and their associated factors on outcomes for advanced PC has yet to be fully investigated. A total of 232 patients were enrolled in this study for the retrospective review of their clinical information and the measurement of skeletal muscle areas at the third lumber vertebra by computed tomography scan to identify CC or SC. The association and concurrent occurrence of clinicopathological features in each patient, prevalence rates, and prognosis with the CC or SC were calculated. CC and SC were observed in 83.6% (n = 194) and 49.1% (n = 114) of PC patients, respectively. Low hemoglobin levels more often occurred in CC patients than in non-CC patients (p = 0.014). Older age (p = 0.000), female gender (p = 0.024), low body mass index (BMI) values (p = 0.004), low hemoglobin levels (p = 0.036), and low albumin levels (p = 0.001) were more often found in SC patients than in non-SC patients. Univariate and multivariate analyses showed that CC was an independent poor prognostic factor of overall survival (OS) and progression-free survival for all patients, the chemotherapy (C/T) subgroup, and the high BMI subgroup. Meanwhile, SC was an independent predictor of poor OS for the subgroups of C/T or high BMI but not for all patients. These findings reveal the clinical differences for CC and SC and provide useful information for predicting the prognosis of advanced PC patients and conducting personalized medicine.

RESUMEN

Both efficacy and tolerability are critical issues in choosing neoadjuvant chemotherapy in patients with unresectable locally advanced pancreatic cancer (LAPC). The optimal regimen and the impact of conversion surgery on patient survival remains insufficiently reported in Asain population. Therefore, we conducted a retrospective study aiming to evaluate the resection rate after different induction chemotherapy regimen and its impact toward survival. All patients with pancreatic cancer treated in our institute from 2013 to 2020, a total of 730 patients, were reviewed and 131 patients with LAPC were identified. For cohort homogeneity, 14 patients receiving induction concurrent chemoradiotherapy initially were excluded and 117 patients receiving induction chemotherapy were included in the study. Most patients (90 of 117, 77%) received triplet induction chemotherapy, including the combination of S1, leucovorin, oxaliplatin and gemcitabine (SLOG) in 48, modified FOLFIRINOX in 21 and the combination of gemcitabine, oxaliplatin, fluorouracil and leucovorin (GOFL) in 21. The tumor response rate (19%-33%), the surgical exploration rate (38%-52%) and the mOS (15.4-23.0 months) were not significantly different among the three triplets. Both GOFL and SLOG regimen had comparable efficacy and less neutropenia as compared to mFOLFIRINOX. Conversion surgery was performed in 34 of 117 (29%) patients after induction chemotherapy. The median overall survival (mOS) in patients with and without conversion surgery were 29.1 and 14.1 months, respectively (P<0.0001). Radiological response alone was not a reliable indicator of successful conversion surgery. Patients who underwent conversion surgery had significantly better survival and thus highlighted the importance of surgical exploration in all patients who did not have progressive disease after induction chemotherapy.
