RESUMO

BACKGROUND: The Internet has become a central source of information on health-related issues. The aim of this study is to assess the quality and readability of online information present on the Whipple surgical procedure by applying recognized scoring tools. METHODS: A search using the top three online search engines (Google, Bing and Yahoo) was conducted in July 2020. Websites were classified as academic, physician, commercial or unspecified. The quality of information was assessed using the JAMA and DISCERN assessment instruments and presence of a HONcode seal. Readability was assessed using the Flesch Reading Ease Score (FRES). RESULTS: A total of 34 unique sources were included in our study. The average JAMA and DISCERN scores of all websites were 2.22 ± 0.48 and 47.28 ± 1.17, respectively, with a median of 1.9 (range 0-4) and 47 (range 18-71), respectively. Website classification distribution was 38% academic, 18% commercial, 9% unspecified, and 1% from physician-based websites. Physician websites had the highest JAMA score with a mean of 3 ± 0.46. Unspecified websites had the highest DISCERN score with a mean of 54.60 ± 1.09. Only 3 websites had the HONcode seal. Physician websites had a significantly higher JAMA mean score than academic websites (p-value = 0.004). Readability was difficult and is on the level of university students. CONCLUSION: The results of this study show a poor quality of online information present on the Whipple surgery. Academic and physician websites need to improve the quality of their websites on the procedure. More HONcode-certified websites are needed as they are the best source for information on this operation.

RESUMO

BACKGROUND: Hepatic epithelioid hemangioendothelioma (HEH) is a rare tumor that can affect multiple organs. Little is known about the pathophysiology, clinical course and management of this disease. The aim of this study is to determine survival rates and elucidate the role of various prognostic factors and therapeutic modalities as compared to surgery on patients with HEH. METHODS: A retrospective analysis on patients diagnosed with HEH between 2004 and 2016 was performed utilizing the SEER database. Kaplan-Meier curves were constructed to determine overall and cancer-specific survival, and the log-rank test was used to compare between groups. To explore prognostic factors and treatment outcomes, univariable and multivariable Cox proportional hazard models were developed. RESULTS: A total of 353 patients with HEH (median age: 50.4 years) were identified. The most common surgery performed was liver resection (90.8%). One-year OS in the surgical group and non-surgical group was 86.6% and 61.0%, respectively, while 5-year OS was 75.2% and 37.4%, respectively. On multivariable analysis, surgery emerged as a favorable prognostic factor [HR (95%CI): 0.404 (0.215-0.758) p value = 0.005]. Age > 65 years [HR (95%CI): 2.548 (1.442-4.506) p value = 0.001] and tumor size > 10 cm [HR (95%CI): 2.401 (1.319-4.37) p value = 0.004] were shown to be poor survival prognostic factors. CONCLUSION: HEH is a rare disease that is poorly understood. Surgical intervention is associated with improved survival rates. Multicenter prospective collaborations are needed to improve our limited knowledge about this neoplasm and determine the optimal treatment strategy.

RESUMO

BACKGROUND/AIM: Distal pancreatectomy (DP) accounts for 25% of all pancreatic resections. Complications following DP occur in around 40% of the cases. Our aim is to analyze short-term surgical outcomes of DP based on whether the indication for resection was benign or malignant pathology, as well as the effect of the surgical approach, open versus laparoscopic on morbidity and mortality. METHODS: We studied all patients undergoing DP from the National Surgery Quality Improvement Program (NSQIP) targeted pancreatectomy participant use file from 2014 to 2016. The patients were divided into 2 groups, those who underwent DP for benign diseases (DP-B) and those who underwent DP for malignant diseases (DP-M). We performed multivariate logistic regression to evaluate the association between benign or malignant distal pancreatectomies and 30-day outcomes. We included clinically and/or statistically significant confounders into the models. We also conducted the same analysis in the subgroups of open and laparoscopic DP. RESULTS: Three thousand five hundred and seventy-nine patients underwent distal pancreatectomy. The most common indication for surgery was malignant disease in 1894 (53%). Thirty-day mortality occurred in 0.4% of DP-B compared to 1.3% DP-M. On multivariate analysis, no significant difference was found in mortality or in the risk of pancreatic fistula between the 2 groups. Bleeding (p = 0.002) and composite morbidity (p = 0.01) were significantly higher in the DP-M group. Among composite morbidities, thromboembolism was significantly associated with DP-M (OR 2.1, p = 0.0004) only when performed with an open approach. CONCLUSION: DP-M is associated with a significantly higher risk of post-operative bleeding, thromboembolism, and sepsis compared to DP-B but no significant increase in mortality. When further analyzing the impact of the operative approach on morbidity, there was an increased rate of post-operative thromboembolic in the DP-M group when the surgery was performed in an open manner and this increased risk was no longer statistically significant if the DP-M was performed using a minimally invasive approach.

RESUMO

BACKGROUND: The debate regarding the merits of routine use of intraoperative cholangiography (IOC) during laparoscopic cholecystectomy (LC) continues to rage. We aim to analyze the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) database to identify patterns of utilization of cholangiography during LC as well as its impact on patient outcomes. STUDY DESIGN: This is a retrospective cohort study of patients undergoing LC with or without IOC in the 2012 and 2013 ACS NSQIP database. Only patients without any preoperative biochemical evidence of the CBD stone were included in the analysis. Comparison between two groups and data analysis focused on the following primary outcomes: 30-day mortality, readmission, return to operating room and NSQIP collected morbidity. RESULTS: Twenty-one percentage of patients undergoing LC without any biochemical abnormality are undergoing IOC. There were no statistically significant differences in thirty-day outcomes between two patient populations with regard to mortality, morbidity, cardiac, central nervous system, wound, deep vein thrombosis, sepsis, respiratory and urinary tract complications. Patients undergoing LC plus IOC were found to have statistically significant reduction in the rate of readmission related to the first operation (adjusted odds ratio 0.80, 95 % CI 0.70-0.92; P value = 0.002). Readmissions related to biliary complications including retained CBD following cholecystectomy were 1.61 times more likely in patients who underwent LC without cholangiography. CONCLUSION: The use of IOC at the time of LC appears to be associated with a statistically significant decrease in re-admission rates, especially readmissions related to biliary complications.

RESUMO

BACKGROUND: The literature is sparse regarding the association between pneumonia and venous thrombosis in surgical patients. The aim of this study was to investigate the risk of postoperative venous thrombosis in patients who fit the criteria for preoperative pneumonia using data from the ongoing American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) database while adjusting for potential confounders. METHODS: This is a cohort study using data from the ACS NSQIP database participating sites from 2008 (211 sites) and 2009 (237 sites). 427,656 patients undergoing major general surgery were included. The 30-day risk of postoperative venous thrombosis including deep vein thrombosis (DVT) and pulmonary embolism (PE) was evaluated in patients with preoperative pneumonia diagnosed before undergoing major general surgery. RESULTS: Patients with preoperative pneumonia had a higher incidence of both 30-day DVT and PE than patients without preoperative pneumonia. After adjusting for all potential confounders, the effect estimates for the association between preoperative pneumonia and venous thrombosis were DVT, OR: 1.67 (95% CI 1.32-2.11) and PE, OR: 2.18 (95% CI 1.48-3.22). CONCLUSIONS: A large, multicenter database of surgical patients showed that preoperative pneumonia may increase risk for developing venous thrombosis. This adds to our understanding of risk factors for venous thrombosis and suggests a potential benefit of diagnosing preoperative pneumonia in patients undergoing major general surgery.

RESUMO

OBJECTIVE: To evaluate 30-day postoperative outcomes in laparoscopic (LS) versus open splenectomy (OS). SUMMARY BACKGROUND DATA: LS has generally been associated with lower rates of postoperative complications than OS. However, evidence mainly comes from small studies that failed to adjust for the confounding effects of the underlying indication or clinical condition that may have favored the use of one technique over the other. METHODS: A retrospective cohort study of patients undergoing splenectomy in 2008 and 2009 using data from the American College of Surgeons National Surgical Quality Improvement Program database (n = 1781). Retrieved data included 30-day mortality and morbidity (cardiac, respiratory, central nervous system, renal, wound, sepsis, venous thromboembolism, and major bleeding outcomes), demographics, indication, and preoperative risk factors. We used multivariate logistic regression to assess the adjusted effect of the splenectomy technique on outcomes. RESULTS: A total of 874 (49.1%) cases had LS and 907 (50.9%) had OS. After adjusting for all potential confounders including the indication and preoperative risk factors, LS was associated with decreased 30-day mortality [OR (odds ratio): 0.39, 95% CI: 0.18-0.84] and postoperative respiratory occurrences (OR: 0.46, 95% CI: 0.27-0.76), wound occurrences (OR: 0.37, 95% CI: 0.11-0.79), and sepsis (OR: 0.52, 95% CI: 0.26-0.89) when compared with OS. Patients who underwent LS also had a significantly shorter total length of hospital stay and were less likely to receive intraoperative transfusions compared with patients who underwent OS. CONCLUSIONS: LS is associated with more favorable postoperative outcomes than OS, irrespective of the indication for splenectomy or the patient's clinical status.

RESUMO

BACKGROUND: Preoperative anaemia is associated with adverse outcomes after cardiac surgery but outcomes after non-cardiac surgery are not well established. We aimed to assess the effect of preoperative anaemia on 30-day postoperative morbidity and mortality in patients undergoing major non-cardiac surgery. METHODS: We analysed data for patients undergoing major non-cardiac surgery in 2008 from The American College of Surgeons' National Surgical Quality Improvement Program database (a prospective validated outcomes registry from 211 hospitals worldwide in 2008). We obtained anonymised data for 30-day mortality and morbidity (cardiac, respiratory, CNS, urinary tract, wound, sepsis, and venous thromboembolism outcomes), demographics, and preoperative and perioperative risk factors. We used multivariate logistic regression to assess the adjusted and modified (nine predefined risk factor subgroups) effect of anaemia, which was defined as mild (haematocrit concentration >29-<39% in men and >29-<36% in women) or moderate-to-severe (≤29% in men and women) on postoperative outcomes. FINDINGS: We obtained data for 227,425 patients, of whom 69,229 (30·44%) had preoperative anaemia. After adjustment, postoperative mortality at 30 days was higher in patients with anaemia than in those without anaemia (odds ratio [OR] 1·42, 95% CI 1·31-1·54); this difference was consistent in mild anaemia (1·41, 1·30-1·53) and moderate-to-severe anaemia (1·44, 1·29-1·60). Composite postoperative morbidity at 30 days was also higher in patients with anaemia than in those without anaemia (adjusted OR 1·35, 1·30-1·40), again consistent in patients with mild anaemia (1·31, 1·26-1·36) and moderate-to-severe anaemia (1·56, 1·47-1·66). When compared with patients without anaemia or a defined risk factor, patients with anaemia and most risk factors had a higher adjusted OR for 30-day mortality and morbidity than did patients with either anaemia or the risk factor alone. INTERPRETATION: Preoperative anaemia, even to a mild degree, is independently associated with an increased risk of 30-day morbidity and mortality in patients undergoing major non-cardiac surgery.

RESUMO

BACKGROUND: The two approaches for performing cholecystectomy are open and laparoscopic ones. This study aims to characterize national trends of cholecystectomies in the United States (US) and determine differences by approach, age group, primary payer, teaching status and location of healthcare center. METHODS: Retrospective analysis of patients undergoing cholecystectomy was done using the US National Inpatient Sample from 1997 to 2011. Trends in open and laparoscopic cholecystectomy were analyzed, as well as comparison between age groups, primary payer, location and teaching status of hospitals operations were performed at. RESULTS: Around 6 million cholecystectomies performed from 1997 to 2011. The laparoscopic approach was significantly more common than the open (P<0.001). A significant decrease in open cholecystectomies is seen since 1997. Age group of 65-84 had significantly the most cases in the open approach (P<0.001), while in laparoscopic the 18-44 age group had the significantly highest amount (P<0.001). Medicare covered the most cases for open, while private insurance covered the most in the laparoscopic approach. Most cases were performed in urban, private non-profit, non-teaching hospitals in both groups. In the laparoscopic group the South had a significantly higher (P<0.001) number of cases compared to all other US regions. CONCLUSIONS: Cholecystectomies remained constant from 1997 to 2011. The number of open cholecystectomies decreased over time in favor of laparoscopic ones. More funding should be given to private non-teaching hospitals as they perform the majority of cholecystectomies nationwide. Better management of cholecystectomy risk factors is needed in the South.

RESUMO

BACKGROUND: Hepatopancreaticobiliary (HPB) diseases carry high morbidity despite efforts aimed at their reduction. An assessment of their trial characteristics is paramount to determine trial design adequacy and highlight areas for improvement. As such, the aim of this study is to assess HPB surgery trial characteristics, summarize logistic, financial, and practical reasons behind early discontinuation, and propose potential interventions to prevent this in the future. METHODS: All clinical trials investigating HPB surgery registered on ClinicalTrials.gov from October 1st, 2007 (inclusive), to April 20th, 2021 (inclusive), were examined. Trial characteristics were collected including, but not limited to, study phase, duration, patient enrollment size, location, and study design. Peer-reviewed publications associated with the selected trials were also assessed to determine outcome reporting. RESULTS: A total of 1776 clinical trials conducted in 43 countries were identified, the majority of which were conducted in the USA. Of these trials, 32% were reported as "completed" whereas 12% were "discontinued." The most common cause of trial discontinuation was low accrual, which was reported in 37% of terminated studies. These resulted in 413 published studies. Most trials had multiple assignment, randomized, or open-label designs. Treatment was the most common study objective (73%) with pharmacological therapy being the most commonly studied intervention. CONCLUSIONS: The main reasons for early discontinuation of clinical trials in HPB surgery are poor patient recruitment and inadequate funding. Improved trial design, recruitment strategies and increased funding are needed to prevent trial discontinuation and increase publication rates of HPB surgery clinical trials.

RESUMO

The use robotics in surgery is gaining momentum. This approach holds substantial promise in pancreas surgery. Robotic surgery for pancreatic lesions and malignancies has become well accepted and is expanding to more and more center annually. The number of centers using robotics in pancreatic surgery is rapidly increasing. The most studied robotic pancreas surgeries are pancreaticoduodenectomy and distal pancreatectomy. Most studies are in their early phases, but they report that robotic pancreas surgery is safe feasible. Robotic pancreas surgery offers several advantages over open and laparoscopic techniques. Data regarding costs of robotics versus conventional techniques is still lacking. Robotic pancreas surgery is still in its early stages. It holds promise to become the new surgical standard for pancreatic resections in the future, however, more research is still needed to establish its safety, cost effectiveness and efficacy in providing the best outcomes.

RESUMO

BACKGROUND: The use of ACS-NSQIP has increased in pancreatic surgery (PS) research. The aim of this study is to critically appraise the methodological reporting of PS publications utilizing the ACS-NSQIP database. STUDY DESIGN: PubMed was queried for all PS studies employing the ACS-NSQIP database published between 2004 and 2021. Critical appraisal was performed using the JAMA-Surgery Checklist, STROBE Statement, and RECORD Statement. RESULTS: A total of 86 studies were included. Median scores for number of fulfilled criteria for the JAMA-Surgery Checklist, STROBE Statement, and RECORD Statement were 6, 20, and 6 respectively. The most commonly unfulfilled criteria were those relating to discussion of missed data, compliance with IRB, unadjusted and adjusted outcomes, providing supplementary/raw information, and performing subgroup analyses. CONCLUSION: An overall satisfactory reporting of methodology is present among PS studies utilizing the ACS-NSQIP database. Areas for improved adherence include discussing missed data, providing supplementary information, and performing subgroup analysis. Due to the increasing role of large-scale databases, enhanced adherence to reporting guidelines may advance PS research.

RESUMO

BACKGROUND: The Model End-Stage Liver Disease (MELD) has been widely used to predict the mortality and morbidity of various surgical procedures. We aimed to assess the impact of preoperative MELD score on adverse 30-day postoperative outcomes following gastrectomy. METHODS: Patients who underwent elective, non-emergent gastrectomy were identified from the ACS NSQIP 2014-2019 database. Patients were categorized according to a calculated MELD score. The primary outcomes of this study were the 30-day overall complications and major complication rates following gastrectomy. RESULTS: Compared to MELD <11, patients with MELD ≥11 had significantly higher rates of mortality, any complication, and major complication. MELD score ≥11 was significantly associated with any complication (OR 1.73, p = 0.011) and major complications (1.85, p = 0.014) on multivariate analysis. CONCLUSIONS: MELD score ≥11 was associated with poorer outcomes in patients undergoing gastrectomy compared to lower MELD scores.

RESUMO

BACKGROUND: International medical graduates (IMGs) have been a critical part of the USA healthcare in the past 30 years, especially in small rural and poor counties. However, little to no publications are present on the distribution of these IMGs across general surgery residency programs. METHODS: All freely accessible information on current residents in accredited general surgery residency programs within the USA with at least a 5-year history was explored for IMGs in the current roster using the AMA residency and fellowship database in 2020. Demographic and geographic data were summarized. RESULTS: A total of 230 general surgery residency program were included. Programs were distributed among 46 (92%) states. Of a total 6304 categorical general surgery residents, 573 (9%) were IMGs. Florida (USA) had the highest total number of current IMG general surgery residents with 64. The highest percentage of current IMG residents was found in Maryland (USA) with 31%. IMGs obtained their medical degrees from 76 different countries worldwide. Grenada was the country with the highest origin of IMGs with 77 residents. Central/North America had the highest origin of IMGs with 217 (38%). CONCLUSIONS: IMGs make up a small portion of current general surgery residents in USA programs. Some states host more IMGs than others. Particular countries have contributed more IMGs than others. More research is needed to the challenges facing IMGs and come up with novel solutions for them.

RESUMO

ABSTRACT: Locally advanced and borderline resectable pancreatic cancers are being increasingly recognized as a result of significant improvements in imaging modalities. The main tools used in diagnosis of these tumors include endoscopic ultrasound, computed tomography, magnetic resonance imaging, and diagnostic laparoscopy. The definition of what constitutes a locally advanced or borderline resectable tumor is still controversial to this day. Borderline resectable tumors have been treated with neoadjuvant therapy approaches that aim at reducing tumor size, thus improving the chances of an R0 resection. Both chemotherapy and radiotherapy (solo or in combination) have been used in this setting. The main chemotherapy agents that have shown to increase resectability and survival are FOLFORINOX (a combination of folinic acid, fluorouracil, irinotecan, and oxaliplatin) and gemcitabine-nab-paclitaxel. Surgery on these tumors remains a significantly challenging task for pancreatic surgeons. More studies are needed to determine the best agents to be used in the neoadjuvant and adjuvant settings, biologic markers for prognostic and operative predictions, and validation of previously published retrospective results.

RESUMO

BACKGROUND: Gastric cancer (GC) is the third most common cause of malignancy associated mortality globally. The cornerstone of curative treatment involves surgical gastrectomy. In this study, we explore clinical trials involving gastrectomy for GC, highlighting inadequacies and underlining promising surgical interventions and strategies. MATERIALS AND METHODS: On 1 May 2020, ClinicalTrials.gov was explored for interventional trials related to gastrectomy for GC, without adding limitations for location or date. All data pertaining to the trials were collected. Characteristics such as phase, duration, enrolment size, location, treatment allocation, masking and primary endpoint were analysed. RESULTS: One hundred thirty-eight clinical trials met the search criteria. Clinical trials were performed in only 14 countries; most of them occurring in China. Most trials (33%) were still in the recruiting phase. On average, the length of trials was 3.9 years. Most trials had parallel assignment, were randomised and masked. The primary endpoint which was mostly commonly studied was overall survival (33%). The most common intervention studied is laparoscopic gastrectomy in 43 (31%) trials. CONCLUSIONS: Our study exposed a small number of trials, publication rate, absence of geographic variety in clinical trials involving gastrectomy for GC. Adequate management of trial design can help decrease duration and increase validity of results. More trials comparing different surgical techniques are needed to update the surgical practice of gastrectomy for GC.

RESUMO

The aim of this study is to identify the optimal timing for cholecystectomy for acute cholecystitis. Patients undergoing cholecystectomy for acute cholecystitis from the National Surgery Quality Improvement Program database between 2014 and 2016 were included. The patients were divided into 4 groups, those who underwent surgery at days 0, 1, 2, or 3+ days. The primary outcome was short-term surgical morbidity and mortality. A total of 21,392 patients were included. After adjusting for confounders, compared to day 0 patients, those who underwent surgery at day 1 and day 2 had lower composite morbidity rate, while day 3+ patients had significantly higher bleeding and mortality rate. Subgroup analysis shows this trend to be more significant in the elderly and in diabetic patients who were delayed. Delay in cholecystectomy for over 72 h from admission is associated with statistically significant increase in bleeding and mortality.

RESUMO

BACKGROUND: The status of the axillary lymph nodes in nonmetastatic lymph node-positive breast cancer (BC) patients remains the single most important determinant of overall survival (OS). Although the absolute number of nodes involved with cancer is important for prognosis, the role of the total number of excised nodes has received less emphasis. Thus, several studies have focused on the utility of the axillary lymph node ratio (ALNR) as an independent prognostic indicator of OS. However, most studies suffered from shortcomings, such as including patients who received neoadjuvant therapy or failing to consider the use of adjuvant therapy and tumor receptor status in their analysis. METHODS: We conducted a single-center retrospective review of 669 patients with nonmetastatic lymph node-positive BC. Data collected included patient demographics; breast cancer risk factors; tumor size, histopathological, receptor, and lymph node status; and treatment modalities used. Patients were subdivided into four groups according to ALNR value (< .25, .25-.49, .50-.74, .75-1.00). Study parameters were compared at the univariate and multivariate levels for their effect on OS. RESULTS: On univariate analysis, both the absolute number of positive lymph nodes and the ALNR were significant predictors of OS. On multivariate analysis, only the ALNR remained an independent predictor of OS, with a 2.5-fold increased risk of dying at an ALNR of >or= .25. CONCLUSIONS: Our study demonstrates that ALNR is a stronger factor in predicting OS than the absolute number of positive axillary lymph nodes.

RESUMO

Post-transplantation lymphoproliferative disorders (PTLDs) are well recognized complications of solid organ transplantation. The vast majority of early PTLDs are B-cell non-Hodgkin lymphomas. PTLDs of T-cell origin occur much less frequently and account for only a minority of cases. T-cell PTLDs have been reported to occur primarily at extranodal sites, commonly affecting bone marrow or splenic tissues. The small bowel is an uncommon site of origin of these tumors with only seven cases of primary intestinal post-transplant T-cell lymphomas reported in the literature. We hereby report a new case of primary intestinal post-transplant T-cell lymphoma, arising 18 years following renal transplantation, along with a literature review of all published cases.

RESUMO

Gastro-bronchial fistula (GBF) is an unusual complication of Nissen fundoplication, particularly when performed via a transabdominal approach. The mechanism of such fistula is thought to be related to a previously untreated ulcer in the mucosa of the wall of the gastric wrap or to a subclinical injury to the gastric wall during the process of division of the short gastric vessels and gastric mobilization. This process is greatly aided by herniation of the wrap into the chest in the postoperative period, placing the stomach in intimate contact with the bronchial tree. The diagnosis of GBF is often difficult to establish and requires a high index of suspicion. Most investigative studies tend to be unrevealing. Historically, an upper gastrointestinal series was the recommended study of choice in the literature. Newer reports, however, highlight the value and importance of upper endoscopy as a diagnostic tool in this condition. The majority of GBF were reported in the era of transthoracic Nissen fundoplication. The incidence of this complication seems to have markedly decreased after the widespread adoption of the transabdominal approach to the treatment of GERD. We are reporting the second case in the literature of a GBF developing after a laparoscopic Nissen fundoplication in a 28-year-old male patient. This case report should serve to increase awareness of this uncommon complication that should be considered in the differential diagnosis of patients with recurrent pneumonia or refractory hemoptysis after major upper gastrointestinal surgical procedures.
