RESUMEN

BACKGROUND: The standard surgery for proximal advanced gastric cancer (PAGC) is total gastrectomy with D2 lymph node dissection (LND). Although prophylactic splenectomy for splenic hilar LND (No. 10) is not recommended due to any survival advantage, prophylactic LND (No. 10) without splenectomy remains controversial. Thus, we aimed to evaluate whether No. 10 LND is essential for patients' survival benefit in PAGC. METHODS: We conducted a retrospective study of 1038 patients with PAGC who underwent total gastrectomy without splenectomy. After adjusting for confounders and propensity score matching (PSM), patients were grouped into Group 1 (D2 LND without splenic hilar LN; n = 288) or Group 2 (D2 LND with splenic hilar LN; n = 288). Variables between the two groups (5-year overall survival [OS] and disease-free survival [DFS]) were compared, as well as in patients with tumors located in the greater curvature and those with Borrmann type IV disease. RESULTS: The 5-year OS and DFS rates after PSM were not significantly different between Groups 1 and 2 (57.3% vs. 62.1%, p = 0.300; 52.8% vs. 59.7%, p = 0.100, respectively). Furthermore, the 5-year OS and DFS rates in patients with greater curvature involvement (54.4% vs. 61.9%, p = 0.500; 50.0% vs. 57.6%, p = 0.400, respectively) and Borrmann type IV disease (23.8% vs. 38.6%, p = 0.400; 16.7% vs. 33.9%, p = 0.200, respectively) after PSM were also not significantly different between the two groups. CONCLUSIONS: Prophylactic splenic hilar LND without splenectomy does not improve long-term survival in PAGC. Therefore, this procedure might not be essential for patients with PAGC as well greater curvature involvement and Borrmann type IV disease.

RESUMEN

The present study investigated the relationship between type of calcaneal fractures and subluxation or dislocation of peroneal tendon. Also, we investigated clinical outcomes of patients with both calcaneal fractures and dislocations or subluxations of peroneal tendons in early surgical treatments (at the time of surgery for calcaneal fractures) and delayed surgical treatment (at the time of surgery for calcaneal plate removal) for dislocations or subluxations of peroneal tendons. We included 151 patients with calcaneal fractures who were followed for ≥2 years after surgery. Among them, 21 cases (13.9%) required reduction for peroneal tendon subluxation or dislocation. Reductions of peroneal tendons were performed at the time of surgery for calcaneal fractures in 11 cases, whereas the other 10 cases were performed during surgery for calcaneal implant removal. As classified by Essex-Lopresti, 94 cases (62.3%) were joint depression type and 17 (18.1%) were accompanied by dislocations or subluxations of peroneal tendons, whereas 57 (37.7%) were tongue type and 4 (7.0%) were accompanied by dislocations or subluxations of peroneal tendons. As classified by the Sanders system, 96 cases (63.6%) were Sanders A fracture lines, and 18 (18.8%) were accompanied by dislocations or subluxations of peroneal tendons. In 55 cases (36.4%) without Sanders A fracture lines, 3 (5.5%) were accompanied by dislocations or subluxations of peroneal tendons. In conclusion, calcaneal fractures with peroneal tendon dislocations are more common in joint depression type and Sander A type. Also, after a ≥2-year follow-up period, there were no significant differences in visual analog scale or foot and ankle outcome score whether reduction of peroneal tendons was done with reduction of fracture or removal of implant of calcaneus.

RESUMEN

BACKGROUND: There is limited information describing the presenting characteristics and dynamic clinical changes in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection diagnosed in the early phase of illness. This study is a case series of patients with coronavirus disease 2019 (COVID-19) admitted to 11 hospitals in Korea. METHODS: Patients with confirmed SARS-CoV-2 infection by positive polymerase chain reaction (PCR) testing of respiratory specimens by active surveillance that were finally discharged between February 20 and April 30, 2020 were included. Patients were classified into mild and non-mild groups on initial admission according to oxygen demand and Sequential Organ Failure Assessment score, and the mild group was followed up and subgrouped into non-aggravation and aggravation groups. RESULTS: A total of 161 patients with SARS-CoV2 infection were enrolled. Among the mild group of 136 patients, 11.7% of patients experienced clinical aggravation during hospitalization, but there was no initial clinical parameter on admission predicting their aggravation. Fever (odds ratio [OR], 4.56), thrombocytopenia (OR, 12.87), fever (OR, 27.22) and lactate dehydrogenase (LDH) > 300 U/L (OR, 18.35), and CRP > 1 mg/dL (OR, 11.31) significantly indicated aggravation in the 1st, 2nd, 3rd, and 4th 5-day periods, respectively. PCR positivity lasted for a median of 22 days and 32 days after the onset of illness in the non-aggravation and aggravation groups, respectively. CONCLUSION: Old age was associated with early severe presentation. Clinical aggravation among asymptomatic or mild patients could not be predicted initially but was heralded by fever and several laboratory markers during the clinical course.

RESUMEN

BACKGROUND: This study was aimed at evaluating the food intake and nutritional status of patients who underwent gastrectomy for gastric cancer based on a large-scale gastric cancer cohort. METHODS: An observational prospective cohort study for gastric cancer has been conducted since 2010. From the cohort data, we selected the data for patients who completed at least 2 days of 3-day diet diaries and who underwent subtotal gastrectomy (STG) or total gastrectomy (TG). As a control group, patients who underwent endoscopic submucosal dissection were also included. The collected diet data were converted to macro- and micronutrients using computerized software, and the nutrient intakes were compared. RESULTS: Among 6,556 patients who participated in the cohort study from 2011 to 2016, 1,289 patients who completed at least 2 days of 3-day diet diaries were included in this study. During the postoperative 3-month period, body weight was significantly decreased in the and TG groups. However, there was no difference in nutrient intake among the 3 groups except vitamin D and calcium intake. Similar results were observed during the postoperative 12 months period. CONCLUSIONS: Postoperative body weight loss and anemia might originate from altered absorptive function and metabolic change after gastrectomy rather than decreased nutrient intake.

RESUMEN

OBJECTIVE: Laparoscopic gastrectomy has been established as a standard treatment for early gastric cancer, and its use is increasing recently. Compared with the conventional laparoscopy-assisted distal gastrectomy (LADG), totally laparoscopic distal gastrectomy (TLDG) involves intracorporeal reconstruction, which can avoid the additional incision, resulting in pain reduction and early recovery. This study aimed to compare the short-term postoperative outcomes of TLDG vs. LADG in gastric cancer in a high-volume center. METHODS: A retrospective cohort study was conducted on 1,322 patients who underwent laparoscopic distal gastrectomy from June 2012 to June 2017 at the National Cancer Center, Korea. LADG was performed in the early period before July 2015, and TLDG was applied in the later period. Postoperative short-term outcomes were compared in terms of complication and clinical course between the two groups. Pain score was measured by rating the pain intensity from 0 to 10 points on postoperative day (POD) 1 and 3. RESULTS: A total of 667 patients underwent LADG and 655 patients underwent TLDG. Clinicopathologic characteristics were not different in both groups. Intraoperative estimated blood loss (EBL) was significantly lower in the TLDG group (P<0.001). Postoperative pain scores were significantly lower in the TLDG group than in the LADG group on POD 1 (5.1±1.5vs. 4.8±1.4, P=0.015). First flatus passage after operation was significantly earlier in the TLDG group (3.4±0.8 d vs. 3.2±0.6 d, P<0.001). There were no differences in postoperative complications and hospital stay between the two groups. CONCLUSIONS: Based on the reported short-term postoperative outcomes, TLDG is safe and feasible as well as LADG. Moreover, compared with LADG, TLDG can reduce intraoperative EBL and postoperative pain and enhance the bowel motility in gastric cancer surgery.

RESUMEN

Coronary artery disease (CAD) is a major determinant of long-term prognosis in patients with peripheral artery disease (PAD). We investigated the predictors of CAD in patients with lower extremity PAD.A total of 107 patients with PAD who underwent peripheral and simultaneous coronary angiography were reviewed. PAD was defined as (≥ 50%) stenosis associated with claudication or critical limb ischemia. PAD was divided into proximal and distal lesions. CAD was defined as angiographically significant (≥ 50%) stenosis of coronary arteries.The prevalence of CAD in patients with PAD was 62% (67/107), and of this 62%, only 13% (9/67) had angina and 72% (48/67) had multi-vessel disease. Diabetes significantly increased the risk of CAD in patients with PAD and the odds ratio of having multi-vessel CAD was 2.5 (1.1-5.9, P = 0.037) in multivariate regression analysis. The patients with multi-vessel CAD had more cardiovascular risk factors than those with normal, minimal and single CAD (P = 0.032). Interestingly, the prevalence of proximal PAD was higher in the normal or single CAD group than the multi-vessel CAD group, whereas both proximal and distal involvement of PAD was higher in the multi-vessel CAD group.Diabetes, multi-cardiovascular risk factors, and involvement of both proximal and distal lesions significantly increased the risk of multi-vessel CAD. Therefore, simultaneous CAD evaluation should be considered in patients with lower extremity PAD having diabetes, multi-cardiovascular risk factors, or multi-level disease.

RESUMEN

BACKGROUND: Lymphatic invasion (LI) is a potent risk factor for lymph node metastasis (LNM) in early gastric cancer (EGC) after endoscopic submucosal dissection (ESD). However, there are also other risk factors for LNM. Hence, to identify the need for additional surgery in some case of EGC without LI, the present study aimed to identify the risk factors for LNM in patients with EGC without LI. METHODS: Data from 2284 patients diagnosed with EGC who underwent curative surgery at National Cancer Center in Korea from January 2012 to May 2019 were collected. The clinicopathological characteristics of patients with EGC without LI were compared on the basis of LNM status. RESULTS: There were 339 (17.1%) and 1648 (82.9%) patients with and without LI respectively. Among these patients with and without LI, 118 (34.8%) and 91 (5.5%) patients presented with LNM, respectively. In patients with EGC without LI, tumor size larger than 3 cm (OR = 2.12, 95% CI = 1.22-3.68; p = 0.007), submucosal invasion (OR = 4.14, 95% CI = 2.57-6.65; p < 0.001), and undifferentiated histologic type (OR = 2.33, 95% CI = 1.45-3.76; p < 0.001) were significant risk factors for LNM. Rates of LNM in patients meeting absolute, expanded, and beyond expanded criteria without LI were 0%, 1.5% (OR = 3.27, 95% CI = 0.18-59.41; p = 0.423), and 7.3% respectively. When the expanded criteria were divided into four subtypes patients with EGC, without LI within each subtype did not show significant risk of incidence of LNM compared to the absolute criteria. CONCLUSIONS: The current expanded criteria for endoscopic resection (ER) are tolerable in cases without LI, even though minimal risk LNM exists. Therefore, additional surgery may not be needed for patients meeting expanded criteria for ER.

RESUMEN

BACKGROUND: Use of appropriate antibiotics for the treatment of pneumonia is integral in patients admitted to intensive care units (ICUs). Although it is recommended that empirical treatment regimens should be based on the local distribution of pathogens in patients with suspected hospital-acquired pneumonia, few studies observe patients admitted to ICUs with nursing home-acquired pneumonia (NHAP). We found factors associated with the use of inappropriate antibiotics in patients with pneumonia admitted to the ICU via the emergency room (ER). METHODS: We performed a retrospective cohort study of 83 pneumonia patients with confirmed causative bacteria admitted to ICUs via ER March 2015-May 2017. We compared clinical parameters, between patients who received appropriate or inappropriate antibiotics using the Mann-Whitney U, Pearson's chi-square, and Fisher's exact tests. We investigated independent factors associated with inappropriate antibiotic use in patients using multivariate logistic regression. RESULTS: Among 83 patients, 30 patients (36.1%) received inappropriate antibiotics. NHAP patients were more frequently treated with inappropriate antibiotics than with appropriate antibiotics (47.2% vs. 96.7%, p<0.001). Methicillin-resistant Staphylococcus aureus was more frequently isolated from individuals in the inappropriate antibiotics-treated group than in the appropriate antibiotics-treated group (7.5% vs. 70.0%, p<0.001). In multivariate analysis, NHAP was independently associated with the use of inappropriate antibiotics in patients with pneumonia admitted to the ICU via ER. CONCLUSION: NHAP is a risk factor associated with the use of inappropriate antibiotics in patients with pneumonia admitted to the ICU via the ER.

RESUMEN

Purpose: Pylorus-preserving gastrectomy (PPG) is known to have both nutritional and functional advantages over distal gastrectomy for the treatment of early gastric cancer. Although laparoscopic surgery is a popular choice, intracorporeal anastomosis is a newly developed technique that is gaining popularity. This study aimed to determine any differences in the oncological, surgical, and functional outcomes of intracorporeal and extracorporeal anastomosis after PPG. Methods: A retrospective analysis was performed on 90 patients for cT1N0 gastric cancer who underwent laparoscopic pylorus preserving gastrectomy from January 2015 to June 2017 at the OOO, Korea; 38 patients underwent intracorporeal (TLPPG) and 52 underwent extracorporeal (LAPPG) anastomosis. The postoperative oncological, surgical, and functional outcomes were compared between the two groups. In order to compare the outcomes in obese patients, the postoperative and functional outcomes in patients with a BMI of ≥25, and in those with abdominal wall thickness measuring ≥28 mm, were evaluated. Results: The TLPPG group showed a significantly reduced wound size (4 cm (3~4) vs 5 cm (5~6), p<0.001) and had fewer wound complaints than the LAPPG group (0.0% vs 15.4%, p=0.01). Postoperative complications were not significantly different between the two groups. In the BMI ≥25 subgroup, the first flatus time after operation was shorter in the TLPPG group (2.9±0.5 vs 3.5±0.8 days, p=0.04). Conclusion: The study demonstrates that both TLPPG and LAPPG are safe and feasible, and that there is a potential benefit for obese patients.

RESUMEN

BACKGROUND: Pulmonary complications including pneumonia and pulmonary edema frequently develop in critically ill surgical patients. Lung ultrasound (LUS) is increasingly used as a powerful diagnostic tool for pulmonary complications. The purpose of this study was to report how LUS is used in a surgical intensive care unit (ICU). METHODS: This study retrospectively reviewed the medical records of 67 patients who underwent LUS in surgical ICU between May 2016 and December 2016. RESULTS: The indication for LUS included hypoxemia (n = 44, 65.7%), abnormal chest radiographs without hypoxemia (n = 17, 25.4%), fever without both hypoxemia and abnormal chest radiographs (n = 4, 6.0%), and difficult weaning (n = 2, 3.0%). Among 67 patients, 55 patients were diagnosed with pulmonary edema (n = 27, 41.8%), pneumonia (n = 20, 29.9%), diffuse interstitial pattern with anterior consolidation (n = 6, 10.9%), pneumothorax with effusion (n = 1, 1.5%), and diaphragm dysfunction (n = 1, 1.5%), respectively, via LUS. LUS results did not indicate lung complications for 12 patients. Based on the location of space opacification on the chest radiographs, among 45 patients with bilateral abnormality and normal findings, three (6.7%) and two (4.4%) patients were finally diagnosed with pneumonia and atelectasis, respectively. Furthermore, among 34 patients with unilateral abnormality and normal findings, two patients (5.9%) were finally diagnosed with pulmonary edema. There were 27 patients who were initially diagnosed with pulmonary edema via LUS. This diagnosis was later confirmed by other tests. There were 20 patients who were initially diagnosed with pneumonia via LUS. Among them, 16 and 4 patients were finally diagnosed with pneumonia and atelectasis, respectively. CONCLUSIONS: LUS is useful to detect pulmonary complications including pulmonary edema and pneumonia in surgically ill patients.

RESUMEN

BACKGROUND: Nitroglycerin (NTG) challenge during head-up tilt-table testing (HUTT) is often utilized to determine the etiology of unexplained vascular syncope. However, conflicting results concerning nitrate-induced hemodynamic changes during HUTT have been reported. The purpose of this study was to assess the determinants of presyncopal symptoms during NTG-stimulated HUTT. METHODS: We evaluated 40 patients with suspected vasovagal syncope. Beat-to-beat changes in blood pressure, heart rate (HR), cardiac index (CI), and systemic vascular resistance (SVR) during HUTT were measured with thoracic impedance cardiography and a plethysmographic finger arterial pressure monitoring device. RESULTS: None of the 40 patients complained of presyncopal symptoms during passive HUTT. However, after the administration of NTG 28 patients showed presyncopal symptoms (NTG+ group) and the remaining 12 patients did not (NTG- group). HR, CI, and the stroke index did not significantly differ between the two groups, whereas mean arterial pressure and SVR were significantly lower in the NTG+ group. CONCLUSIONS: Presyncopal symptoms during NTG-stimulated HUTT are SVR mediated, not cardiac output mediated. This study challenges the conventional idea of a decrease in cardiac output mediated by NTG as the overriding cause of presyncopal symptoms during HUTT.

RESUMEN

BACKGROUND: Failure to achieve optimal stent expansion poses a risk of treatment failure in percutaneous coronary intervention (PCI). Although intravascular ultrasound provides useful information for suboptimal stent expansion, a substantial portion of PCIs are currently being performed under angiographic guidance only. AIM: In order to evaluate the adequacy of stent expansion of four widely used drug-eluting stents in angiography-guided PCI, we performed a retrospective analysis of lesions undergoing PCI using quantitative coronary angiography. METHODS: A total of 112 de novo lesions were analysed. Minimal lumen diameter (MLD) was measured at peak pressure during stent deployment (MLD1), after stent deployment (MLD2), and after postdilatation (MLD3). Stent underexpansion, stent elastic recoil, and stent deficit were calculated. Optimal stent deployment was defined as final MLD ≥ 90% of predicted diameter. RESULTS: For deploying a stent balloon, higher than nominal pressure was used in 83% of cases (93/112). However, optimal deployment was observed in only 32% (36/112). Adjuvant post-dilatation was performed in 59% (45/76) of lesions with suboptimal expansion, which increased the optimal deployment rate by 60% (27/45). Final optimal stent deployment rate was achieved in 56% (63/112). We found that the MLD1 (p = 0.04), MLD3 (p = 0.02), final MLD (p = 0.04), and optimal stent deployment rate (p = 0.036) were significantly reduced in longer stent deployment lesions (≥ 20 mm) compared to shorter lesions (< 20 mm). CONCLUSIONS: Stent length may be a contributing factor of suboptimal stent expansion in angiography-guided PCI.

RESUMEN

Basaloid squamous cell carcinoma is a rare and aggressive variant of squamous cell carcinoma, which mostly occurs in the upper aerodigestive tracts. Basaloid squamous cell carcinoma also typically arises in the anal canal, but is extremely rare in the lower gastrointestinal tract. A 70-year-old man presented with loose stool and intermittent hematochezia 2 months ago. Colonoscopy showed an ulceroinfiltrative mass on the rectosigmoid colon from 16 cm to 18 cm above the anal verge. Conventional colonoscope could not pass through the lesion but it was possible with pediatric colonoscope. Abdominal CT scan showed 1.6 cm sized wall thickening with circumferential luminal narrowing in the rectosigmoid colon and multiple ill-defined low density masses in both lobes of the liver. Therefore, colon cancer with liver metastasis was suspected. However, basaloid cells were noted on histologic examination, and they were weakly positive for synaptophysin on immunohistochemical study. After palliative lower anterior resection, histologic examination of the resected specimen revealed basaloid differentiation with keratin pearls, and tumor cells were positively stained with high molecular weighted cytokeratin (34BE12) and CK 5/6. Thus, the patient was finally diagnosed with basaloid squamous cell carcinoma of rectosigmoid colon with distant metastases.
