RESUMO

The 'Basket-in-Catheter' (BIC) technique facilitates basket-only laparoscopic transcystic exploration (LTCE), increasing its success rate. Using the cholangiography catheter as a sheath is easier and safer than inserting the wire basket-alone. This study evaluates its benefits in confirmed and suspected ductal stones. Retrospective analysis of prospectively collected data on patients with pre-operative or operative suspicion of bile duct stones or with positive and equivocal intraoperative cholangiographies (IOC) who had LTCE attempted using blind basket trawling, without choledochoscopy, were reviewed. The incidence and outcomes of blind basket LTCEs attempted before and after introducing the BIC technique, whether or not stones were retrieved, were analysed. Blind basket LTCE was attempted in 732 patients. Of 377 (51.5%) patients undergoing successful stone retrieval, only 62% had pre-operative clinical and radiological risk factors for ductal stones, 25% had operative risk factors and 13% had silent stones discovered on IOC. Another 355 patients (48.5%) had negative trawling, although one half had pre-operative risk factors for ductal stones and 47.6% had operative risk factors, e.g. cystic duct stones or dilatation. This cohort had equivocal cholangiography in 25.9%. Following basket trawling, repeat IOC confirmed resolution of abnormalities. As no stones were retrieved, these were not considered duct explorations. The BIC technique facilitates safe and speedy bile duct clearance when stones are confirmed, avoiding choledochotomies, without significant complications. BIC duct trawling is also beneficial in patients with suspected ductal stones, helping to resolve equivocal IOCs. It helps surgeons to acquire and consolidate ductal exploration skills.

RESUMO

BACKGROUND: A gap remains between the mounting evidence for single session management of bile duct stones and the adoption of this approach. Laparoscopic bile duct exploration (LBDE) is limited by the scarcity of training opportunities and adequate equipment and by the perception that the technique requires a high skill-set. The aim of this study was to create a new classification of difficulty based on operative characteristics and to stratify postoperative outcomes of easy vs. difficult LBDE irrespective of the surgeon's experience. METHODS: A cohort of 1335 LBDEs was classified according to the location, number and size of ductal stones, the retrieval technique, utilisation of choledochoscopy and specific biliary pathologies encountered. A combination of features indicated easy (Grades I and II A & B) or difficult (Grades III A and B, IV and V) transcystic or transcholedochal explorations. RESULTS: 78.3% of patients with acute cholecystitis or pancreatitis, 37% with jaundice and 46% with cholangitis had easy explorations. Difficult explorations were more likely to present as emergencies, with obstructive jaundice, previous sphincterotomy and dilated bile ducts on ultrasound scans. 77.7% of easy explorations were transcystic and 62.3% of difficult explorations transductal. Choledochoscopy was utilised in 23.4% of easy vs. 98% of difficult explorations. The use of biliary drains, open conversions, median operative time, biliary-related complications, hospital stay, readmissions, and retained stones increased with the difficulty grade. Grades I and II patients had 2 or more hospital episodes in 26.5% vs. 41.2% for grades III to V. There were 2 deaths in difficulty Grade V and one in Grade IIB. CONCLUSION: Difficulty grading of LBDE is useful in predicting outcomes and facilitating comparison between studies. It ensures fair structuring and assessment of training and progress of the learning curve. LBDEs were easy in 72% with 77% completed transcystically. This may encourage more units to adopt this approach.

RESUMO

BACKGROUND: The physiological changes of pregnancy increase the risk of gallstone formation and choledocholithiasis. Traditionally, endoscopic retrograde cholangiopancreatography (ERCP) has been the main approach for managing choledocholithiasis during pregnancy, but recent progress in laparoscopic bile duct exploration (LBDE) has demonstrated this technique as a safe and effective alternative option. METHODS: A retrospective multicenter study of all patients who underwent LBDE during pregnancy from five centers with proven experience in LBDE between January 2010 and June 2020 was performed. The primary endpoint was to analyze the role of LBDE during pregnancy and to further characterize its position as a safe and effective alternative for the management of choledocholithiasis. A systematic review of the published literature relating to LBDE during pregnancy until February 2022 was also performed. RESULTS: Five institutions reported performing LBDE during pregnancy in 8 patients. Median surgical time was 75 min (range: 60-140 min). The bile duct was cleared successfully in all patients, and the median hospital stay was 2 days (range: 1-3 days). The literature review identified a total of 7 patients with a successful CBD clearance rate of 86%. There were no major maternal, fetal, or pregnancy-related complications in any of the total 15 patients included. The symptomatic common bile duct lithiasis with deranged liver function tests was the most frequent indication (n=7). CONCLUSION: LBDE during pregnancy appears to be safe and effective. More evidence reporting outcomes of LBDE during pregnancy is needed before any strong recommendations can be made.

RESUMO

OBJECTIVE: This study aims to examine the indications, techniques, and outcomes of choledochoscopy during laparoscopic bile duct exploration and evaluate the results of the wiper blade maneuver (WBM) for transcystic intrahepatic choledochoscopy. SUMMARY OF BACKGROUND DATA: Choledochoscopy has traditionally been integral to bile duct explorations. However, laparoscopic era studies have reported wide variations in choledochoscopy availability and use, particularly with the increasing role of transcystic exploration. METHODS: The indications, techniques, and operative and postoperative data on choledochoscopy collected prospectively during transcystic and choledo- chotomy explorations were analyzed. The success rates of the WBM were evaluated for the 3 mm and 5 mm choledochoscopes. RESULTS: Of 935 choledochoscopies, 4 were performed during laparoscopic cholecystectomies and 931 during 1320 bile duct explorations (70.5%); 486 transcystic choledochoscopies (52%) and 445 through choledochotomies (48%). Transcystic choledochoscopy was utilized more often than blind exploration (55.7%% vs 44.3%) in patients with emergency admissions, jaundice, dilated bile ducts on preoperative imaging, wide cystic ducts, and large, numerous or impacted bile duct stones. Intrahepatic choledochoscopy was successful in 70% using the 3 mm scope and 81% with the 5 mm scope. Choledochoscopy was necessary in all 124 explorations for impacted stones. Twenty retained stones (2.1%) were encountered but no choledochoscopy related complications. CONCLUSIONS: Choledochoscopy should always be performed during a chol- edochotomy, particularly with multiple and intrahepatic stones, reducing the incidence of retained stones. Transcystic choledochoscopy was utilized in over 50% of explorations, increasing their rate of success. When attempted, the transcystic WBM achieves intrahepatic access in 70%-80%. It should be part of the training curriculum.

RESUMO

PURPOSE: This study sought to investigate the acceptance rate and associated factors of COVID-19 vaccines among dentists and dental students in seven countries. MATERIAL AND METHODS: A structured questionnaire prepared and guided by the report of the SAGE Working Group on Vaccine Hesitancy was distributed among groups of dentists and dental students in seven countries across four continents. RESULTS: A total of 1527 subjects (850 dentists and 677 dental students) participated in this survey. Although 72.5% of the respondents reported their intention to accept COVID-19 vaccines (dentists: 74.4%, dental students: 70.2%), there was a significant difference in agreement between dentists/dental students across countries; generally, respondents in upper-middle-, and high-income countries (UM-HICs) showed significantly higher acceptance rates compared to those in low- and lower-middle income countries (L-LMICs). Potential predictors of higher vaccine acceptance included being a dentist, being free of comorbidity, being well-informed about COVID-19 vaccines, having better knowledge about COVID-19 complications, having anxiety about COVID-19 infection, having no concerns about the side effects of the produced vaccines and being a resident of an UM-HIC. CONCLUSION: The results of our survey indicate a relatively good acceptance rate of COVID-19 among the surveyed dentists and dental students. However, dentists and dental students in L-LMICs showed significantly lower vaccine acceptance rates and trust in COVID-19 vaccines compared to their counterparts in UM-HICs. Our results provide important information to policymakers, highlighting the need for implementation of country-specific vaccine promotion strategies, with special focus on L-LMICs.

RESUMO

Several studies support the notion that inflammation plays a role in the pathophysiology and treatment approaches of psychiatric illnesses, particularly mood disorders. Congruently, classic anti-inflammatory drugs were found efficacious in randomized clinical trials of patients with mood disorders. Moreover, accumulating data indicate that psychotropic drugs exhibit some anti-inflammatory effects. This study was undertaken to examine the efficacy of dexamethasone (a potent corticosteroid) and pentoxifylline (a methylxanthine drug with proven anti-tumor necrosis factor-α inhibitory activity) in behavioral models in rats, which were treated intraperitoneally with either dexamethasone or pentoxifylline for two weeks and then subjected to a battery of behavioral tests. Treatment with pentoxifylline, but not dexamethasone, was associated with antidepressant-like and anti-manic-like effects. The beneficial behavioral effects of pentoxifylline were accompanied by a prominent reduction in pro-inflammatory mediator levels in the brain. For the first time, the current work proves the efficacy of pentoxifylline against both mania-like and depressive-like behaviors. These results suggest that pentoxifylline may be a promising therapeutic intervention for patients with mood disorders. Taking into account the excellent tolerability profile of pentoxifylline in humans, it is warranted to conduct randomized clinical trials to investigate its therapeutic efficacy in patients with psychiatric disorders.

RESUMO

Background: Accumulative data links inflammation and immune dysregulation to the pathophysiology of mental disorders; little is known regarding leukotrienes' (LTs) involvement in this process. Circumstantial evidence suggests that treatment with leukotriene modifying agents (LTMAs) such as montelukast (MTK) may induce adverse neuropsychiatric events. Further methodic evaluation is warranted. Objective: This study aims to examine behavioral effects, as well as inflammatory mediator levels of chronic MTK treatment in male and female rats. Methods: Depression-like phenotypes were induced by exposing male and female rats to a chronic unpredictable mild stress (CUMS) protocol for four weeks. Thereafter, rats were treated (intraperitoneally) once daily, for two weeks, with either vehicle (dimethyl sulfoxide 0.2 ml/rat) or 20 mg/kg MTK. Following treatment protocols, behavioral tests were conducted and brain regions were evaluated for inflammatory mediators including tumor necrosis factor (TNF)-α, interleukin (IL)-6 and prostaglandin (PG) E2. Results: Overall, MTK did not invoke negative behavioral phenotypes (except for an aggression-inducing effect in males). Numerous positive behavioral outcomes were observed, including reduction in aggressive behavior in females and reduced manic/hyperactive-like behavior and increased sucrose consumption (suggestive of antidepressant-like effect) in males. Furthermore, in control males, MTK increased IL-6 levels in the hypothalamus and TNF-α in the frontal cortex, while in control females it generated a robust anti-inflammatory effect. In females that were subjected to CUMS, MTK caused a prominent reduction in TNF-α and IL-6 in brain regions, whereas in CUMS-subjected males its effects were inconsistent. Conclusion: Contrary to prior postulations, MTK may be associated with select beneficial behavioral outcomes. Additionally, MTK differentially affects male vs. female rats in respect to brain inflammatory mediators, plausibly explaining the dissimilar behavioral phenotypes of sexes under MTK treatment.

RESUMO

OBJECTIVES: The challenges posed by laparoscopic cholecystectomy (LC) in obese patients and the methods of overcoming them have been addressed by many studies. However, no objective tool of reporting operative difficulty was used to adjust the outcomes and compare studies. The aim of this study was to establish whether obesity adds to the difficulty of LC and laparoscopic common bile duct exploration (LCBDE) and affects their outcomes on a specialist biliary unit with a high emergency workload. METHODS: A prospectively maintained database of 4699 LCs and LCBDEs performed over 19 years was analysed. Data of patients with body mass index (BMI) ≥ 35, defined as grossly obese, was extracted and compared to a control group. RESULTS: A total of 683 patients (14.5%) had a mean BMI of 39.9 (35-63), of which 63.4% met the definition of morbidly obese. They had significantly more females and significantly higher ASA II classifications. They had equal proportions of emergency admissions, similar incidence of operative difficulty grades 4 or 5 and no open conversions and were less likely to undergo LCBDE than non-obese patients. There were no significant differences in median operative times, morbidity, readmission or mortality rates. CONCLUSIONS: This study, the first to classify gall stone surgery in obese patients according to operative difficulty grading, showed no difference in complexity when compared to the non-obese. Refining access and closure techniques is key to avoiding difficulties. Index admission surgery for biliary emergencies prevents multiple admissions with potential complications and should not be denied due to obesity.

RESUMO

BACKGROUND: The timing of laparoscopic cholecystectomy (LC) for emergency biliary admissions remains inconsistent with national and international guidelines. The perception that LC is difficult in acute cholecystitis and the popularity of the two-session approach to pancreatitis and suspected choledocholithiasis result in delayed management. METHODS: Analysis of prospectively maintained data in a unit adopting a policy of "intention to treat" during the index admission. The aim was to study the incidence of previous biliary admissions and compare the operative difficulty, complications and postoperative outcomes with patients who underwent index admission LC. RESULTS: Of the 5750 LC performed, 20.8% had previous biliary episodes resulting in one admission in 93% and two or more in 7%. Most presented with biliary colic (39.6%) and acute cholecystitis (27.6%). A previous biliary history was associated with increased operative difficulty (p < 0.001), longer operating times (86.9 vs. 68.1 min, p < 0.001), more postoperative complications (7.8% vs. 5.4%, p = 0.002) and longer hospital stay (8.1 vs. 5.5 days, p < 0.001) and presentation to resolution intervals. However, conversion and mortality rates showed no significant differences. CONCLUSION: Index admission LC is superior to interval cholecystectomy and should be offered to all patients fit for general anaesthesia regardless of the presenting complaints. Subspecialisation should be encouraged as a major factor in optimising resource utilisation and postoperative outcomes of biliary emergencies.

RESUMO

BACKGROUND: Recently there has been a growing interest in the laparoscopic management of common bile duct stones with gallbladder in situ (LBDE), which is favoring the expansion of this technique. Our study identified the standardization factors of LBDE and its implementation in the single-stage management of choledocholithiasis. METHODS: A retrospective multi-institutional study among 17 centers with proven experience in LBDE was performed. A cross-sectional survey consisting of a semi-structured pretested questionnaire was distributed covering the main aspects on the use of LBDE in the management of choledocholithiasis. RESULTS: A total of 3950 LBDEs were analyzed. The most frequent indication was jaundice (58.8%). LBDEs were performed after failed ERCP in 15.2%. The most common approach used was the transcystic (63.11%). The overall series failure rate of LBDE was 4% and the median rate for each center was 6% (IQR, 4.5-12.5). Median operative time ranged between 60-120 min (70.6%). Overall morbidity rate was 14.6%, with a postoperative bile leak and complications ≥3a rate of 4.5% and 2.5%, respectively. The operative time decreased with experience (P = .03) and length of hospital stay was longer in the presence of a biliary leak (P = .04). Current training of LBDE was defined as poor or very poor by 82.4%. CONCLUSION: Based on this multicenter survey, LBDE is a safe and effective approach when performed by experienced teams. The generalization of LBDE will be based on developing training programs.

RESUMO

BACKGROUND: Complications following laparoscopic cholecystectomy (LC) and common bile duct exploration (CBDE) for the management of gallstones or choledocholithiasis impact negatively on patients' quality of life and may lead to reinterventions. This study aims to evaluate the causes and types of reintervention following index admission LC with or without CBDE. METHODS: A prospectively maintained database of LC and CBDE performed by a single surgeon was analysed. Preoperative factors, difficulty grading and perioperative complications requiring reintervention and readmissions were examined. RESULTS: Reinterventions were required in 112 of 5740 patients (2.0%), 89 (1.6%) being subsequent to complications. The reintervention cohort had a median age of 64 years, were more likely to be females (p < 0.0023) and to be emergency admissions (67.9%, p < 0.00001) with obstructive jaundice (35.7%, p < 0.00001). 46.4% of the reintervention cohort had a LC operative difficulty grade IV or V and 65.2% underwent a CBDE. Open conversion was predictive of the potential for reintervention (p < 0.00001). The most common single cause of reintervention was retained stones (0.5%) requiring ERCP followed by bile leakage (0.3%) requiring percutaneous drainage, ERCP and relaparoscopy. Relaparoscopy was necessary in 17 patients and open surgery in 13, 6 of whom not resulting from complications. There were 5 deaths. CONCLUSION: This large series had a low incidence of reinterventions resulting from complications in spite of a high workload of index admission surgery for biliary emergencies and bile duct stones. Surgical or endoscopic reinterventions following LC alone occurred in only 0.8%. The most common form of reintervention was ERCP for retained CBD stones. This important outcome parameter of laparoscopic biliary surgery can be optimised through early diagnosis and timely reintervention for complications.

RESUMO

PURPOSE: The main sources of post-cholecystectomy bile leakage (PCBL) not involving major duct injuries are the cystic duct and subvesical/hepatocystic ducts. Of the many studies on the diagnosis and management of PCBL, few addressed measures to avoid this serious complication. The aim of this study was to examine the causes and mechanisms leading to PCBL and to evaluate the effects of specific preventative strategies. METHODS: A prospectively maintained database of 5675 consecutive laparoscopic cholecystectomies was analysed. Risk factors for post-cholecystectomy bile leakage were identified and documented and technical modifications and strategies were adopted to prevent this complication. The incidence, causes and management of patients who suffered bile leaks were studied and their preoperative characteristics, operative data and postoperative outcomes were compared with patients where potential risks were identified and PCBL avoided and with the rest of the series. RESULTS: Twenty-five patients (0.4%) had PCBL (7 expected and less than half requiring reintervention): 11 from cystic ducts (0.2%), 3 from subvesical ducts (0.05%) and 11 from unconfirmed sources (0.2%). The incidence of cystic duct leakage was significantly lower with ties (0.15%) than with clips (0.7%). Fifty-two percent had difficulty grades IV or V, 36% had empyema or acute cholecystitis and 16% had contracted gallbladders. Twelve patients required 17 reinterventions before PCBL resolved; 7 percutaneous drainage, 6 ERCP and 4 relaparoscopy. The median hospital stay was 17 days with no mortality. Hepatocystic ducts were encountered in 72 patients (1.3%) and were secured with loops (54.2%), ties (25%) or sutures (20.8%) with no PCBL. Eighteen sectoral ducts were identified and secured. CONCLUSION: Ligation of the cystic duct reduces the incidence of PCBL resulting from dislodged endoclips. Careful blunt dissection in the proper anatomical planes avoiding direct or thermal injury to subvesical and sectoral ducts and a policy of actively searching for hepatocystic ducts during gallbladder separation to identify and secure them can reduce bile leakage from such ducts.

RESUMO

BACKGROUND: Open conversion rates during laparoscopic cholecystectomy vary depending on many factors. Surgeon experience and operative difficulty influence the decision to convert on the grounds of patient safety but occasionally due to technical factors. We aim to evaluate the difficulties leading to conversion, the strategies used to minimise this event and how subspecialisation influenced conversion rates over time. METHODS: Prospectively collected data from 5738 laparoscopic cholecystectomies performed by a single surgeon over 28 years was analysed. Routine intraoperative cholangiography and common bile duct exploration when indicated are utilised. Patients undergoing conversion, fundus first dissection or subtotal cholecystectomy were identified and the causes and outcomes compared to those in the literature. RESULTS: 28 patients underwent conversion to open cholecystectomy (0.49%). Morbidity was relatively high (33%). 16 of the 28 patients (57%) had undergone bile duct exploration. The most common causes of conversion in our series were dense adhesions (9/28, 32%) and impacted bile duct stones (7/28, 25%). 173 patients underwent fundus first cholecystectomy (FFC) (3%) and 6 subtotal cholecystectomy (0.1%). Morbidity was 17.3% for the FFC and no complications were encountered in the subtotal cholecystectomy patients. These salvage techniques have reduced our conversion rate from a potential 3.5% to 0.49%. CONCLUSION: Although open conversion should not be seen as a failure, it carries a high morbidity and should only be performed when other strategies have failed. Subspecialisation and a high emergency case volume together with FFC and subtotal cholecystectomy as salvage strategies can reduce conversion and its morbidity in difficult cholecystectomies.

RESUMO

OBJECTIVE: The primary aim of this study was to describe the service model of one-session management, with a limited role for preoperative endoscopic clearance. The secondary aim was to review the outcomes and long term follow up in comparison to available studies on LCBDE. BACKGROUND: The laparoscopic era brought about a decline in the conventional surgical management of common bile duct stones. Preoperative endoscopic removal became the primary method of managing choledocholithiasis. Although LCBDE deals with gallstones and ductal stones in onw session, the limited availability of such an advanced procedure perpetuated the reliance on the endoscopic approach. METHODS: Prospective data was entered into a single surgeon's database containing 5739 laparoscopic cholecystectomy over 28 years and analyzed. RESULTS: One thousand eighteen consecutive LCBDE were included (23% of the series). Intraoperative cholangiography was performed in 1292 (98.0%). The median age was 60 years, male to female ratio 1:2 and 75% were emergency admissions. Most patients (43.4%) presented with jaundice. 66% had transcystic explorations and one third through a choledochotomy with 2.1% retained stones, 1.2% conversion, 18.7% morbidity, and 0.2% mortality. Postoperative ERCPs were needed in 3.1%. Recurrent stones occurred in 3%. CONCLUSIONS: One stage LCBDE is a safe and cost-effective treatment where the expertise and equipment are available. Endoscopic treatment has a role for specific indications but remains the first-line treatment in most units. This study demonstrates that establishing specialist services through training and logistic support can optimize the outcomes of managing common bile duct stones.

RESUMO

Despite established efficacy in bipolar disorder patients, lithium (Li) therapy has serious side effects, particularly chronic kidney disease. We examined the safety and behavioral effects of combined chronic low-dose aspirin plus low-dose Li in rats to explore the toxicity and therapeutic potential of this treatment. Rats were fed regular or Li-containing food (0.1% [low-dose, LLD-Li] or 0.2% [standard-dose, STD-Li]) for six weeks. Low-dose aspirin (1 mg/kg) was administered alone or together with Li. Renal function and gastric mucosal integrity were assessed. The effects of the combination treatment were evaluated in depression-like and anxiety-like behavioral models. Co-treatment with aspirin did not alter plasma Li levels. Chronic STD-Li treatment resulted in significant polyuria and polydipsia, elevated blood levels of creatinine and cystatin C, and increased levels of kidney nephrin and podocin-all suggestive of impaired renal function. Aspirin co-treatment significantly damped STD-Li-induced impairments in kidney parameters. There were no gastric ulcers or blood loss in any treatment group. Combined aspirin and LLD-Li resulted in a significant increase in sucrose consumption, and in the time spent in the open arms of an elevated plus-maze compared with the LLD-Li only group, suggestive of antidepressant-like and anxiolytic-like effects, respectively. Thus, we demonstrate that low-dose aspirin mitigated the typical renal side effects of STD-Li dose and enhanced the beneficial behavioral effects of LLD-Li therapy without aggravating its toxicity.

RESUMO

Children with epilepsy are at risk for impaired social cognition and autism. We aimed at evaluating the utility of the social responsiveness scale (SRS) for assessment of social impairment in these children. Prospective study; the SRS was applied to a group of children with epilepsy and a healthy control group. Intellectual disability in the epilepsy group was assessed utilizing adapted versions of the Wechsler Intelligence and adaptive behavior scales. One hundred and one children with epilepsy and 92 healthy children were included. The majority of children in both groups had normal SRS scores. Significant differences were identified in children with high total scores indicating significant deficiencies in reciprocal social behavior; high scores were found in 16% of children with epilepsy versus 7% of normal children, p < .05, particularly involving social communication, p < .05. Intellectual disability was identified in 42% of children with epilepsy, particularly processing speed index, p < .001. Intellectual disability had a significant effect on total scores, p = .016. Children with epilepsy have increased risk of social impairments. Social impairments are more likely in the presence of intellectual disability. The SRS is a quick identification tool that can be employed in the outpatient setting.

RESUMO

OBJECTIVES: Published discrepancy rates between emergency department (ED) and hospital discharge (HD) diagnoses vary widely (from 6.5 to 75.6%). The goal of this study was to determine the extent of diagnostic discrepancy and its impact on length of hospital stay (LOS), up-triage to the intensive care unit (ICU) and in-hospital mortality. METHODS: A retrospective chart review of adult patients admitted from the ED to a hospitalist service at a tertiary hospital was performed. The ED and HD diagnoses were compared and classified as concordant, discordant, or symptom diagnoses according to predefined criteria. Logistic regression analysis was conducted to examine the associations of diagnostic discordance with in-hospital mortality and up-triage to the ICU. A linear regression model was used for the length of stay. RESULTS: Of the 636 patients whose records were reviewed, 418 (217 [51.9%] women, with a mean age of 64.1 years) were included. Overall, 318 patients (76%) had concordant diagnoses, while 91 (21.77%) had discordant diagnoses. Only 9 patients (2.15%) had symptom diagnoses. A discordant diagnosis was associated with increased mortality (OR: 3.64; 95% CI: 1.026-12.91; p=0.045) and up-triage to the ICU (OR: 5.51; 95% CI: 2.43-12.5; p<0.001). The median LOS was significantly greater for patients with discordant diagnoses (7 days) than for those with concordant diagnoses (4.7 days) (p=0.004). Symptom diagnosis did not affect the mortality or ICU up-triage. CONCLUSIONS: One in five hospitalized patients had discordant HD and admission diagnoses. This diagnostic discrepancy was associated with significant impacts on patient morbidity and mortality.

RESUMO

AIM: This study aims to evaluate the incidence, indications, management, and long term follow up of cholecystectomy in patients with no gallstones, other than acalculous acute cholecystitis. METHODS: Prospectively collected data of 5675 patients undergoing laparoscopic cholecystectomy (LC) over 28 years was extracted and analyzed. Patients with biliary symptoms, no stones on ultrasound scans and abnormal hepatobiliary iminodiacetic acid scans, and those with confirmed gallbladder polyps (GBP) were included. RESULTS: Two percent of cholecystectomies were performed in patients with acalculous pathology [1.3% functional gallbladder disorder (FGBD) and 0.7% GBP]. The 114 patients were younger, had lower American Society of Anesthesiologists classification, and had fewer previous biliary admissions than those with gallstones (5560). The clinical presentations of FGBD were chronic biliary symptoms (93.1%) and acute biliary pain (6.9%). GBP patients presented with chronic biliary symptoms. LC in 98.6% FGBD and 92.8% GBP were significantly easier than those for gall stones (P < 0.0001). They were significantly (P < 0.0001 FGBD and P < 0.001 GBP) less likely to have adhesions to the gallbladder. This ease was reflected in shorter operation times and lower utilization of abdominal drains. Polyp numbers ranged from 1 to 30 and sizes from 1 mm to 11 mm. No malignant polyps were encountered. In 95.8% FGBD and 95% GBP, patients had a good symptomatic response to LC. CONCLUSIONS: FGBD and GBP are uncommon in patients undergoing LC. FGBD should be considered during evaluation of right upper quadrant pain with no gall stones. Laparoscopic cholecystectomy may be considered as it achieves long term symptomatic relief in most patients with FGBD and GBP.

RESUMO

Bacterial coinfections which are infections present early in the course of coronavirus disease 2019 (COVID-19) infections before hospitalizations during the 2020 pandemic are rare. A 66-year-old male presented to the ED with a two-week history of subjective fever, dyspnea, and productive cough. He was diagnosed with coinfection of severe COVID-19 pneumonia and pneumococcal infection. He recovered from both infections and was discharged home. This report presents the features of this case and reviews the literature of similar cases of coinfection of COVID-19 pneumonia and pneumococcal infection.
