Comparison of percutaneous gallbladder aspiration with percutaneous cholecystostomy in acute cholecystostomy patients. Can gall bladder aspiration alone be sufficient?

BACKGROUND: The aim of this study is to compare the efficacy and complication rates of percutaneous gallbladder aspiration (PA) and percutaneous cholecystostomy (PC) in the management of AC and present the experiences of a single third-line center. METHODS: The results of 159 patients with AC who admitted to our hospital between 2015 and 2020, that underwent PA and PC procedures, because they did not respond to conservative treatment and LC could not be performed, were retrospectively analyzed. Clinical and laboratory data before and 3 days after PC and PA procedure, technical success, complications, response to treatment, duration of hospital stay, and reverse transcriptase-polymerase chain reaction (RT-PCR) test results were recorded. RESULTS: Out of 159 patients, 22 (8 men 14 women) underwent PA procedure and 137 (57 men 80 women) underwent PC. No significant difference was detected between the PA and PC groups in terms of clinical recovery (P: 0.532) and duration of hospital stay (P: 0.138) in 72 h. The technical success of both procedures was 100%. While 20 out of 22 patients with PA were having a noticable recovery, only one was treated with twice PA procedures and a complete recovery was observed (4.5%). Complication rates were low in both groups and were statistically insignificant (P: 1.00). CONCLUSION: In this pandemic period, PA and PC procedures are effective, reliable, and successful treatment method that can be applied at the bedside for critical patients with AC who are not compatible with surgery, which are safe for health workers and low-risk minimal invasive procedures for patients. In uncomplicated AC patients, PA should be performed, and if there is no response to treatment, PC should be reserved as a salvage procedure. The PC procedure should be performed in patients with AC who have developed complications and are not suitable for surgery.

A surprising culprit for delayed gastrointestinal bleeding after endoscopic ultrasound-guided cholecystoduodenostomy: the double-pigtail stent.

Endoscopic ultrasound-guided gallbladder drainage using a lumen-apposing metal stent has emerged as an accepted option for the treatment of acute cholecystitis in patients unfit for surgery. While metal stents carry a risk of intra- and post-procedural bleeding, the coaxial placement of a double-pigtail stents through lumen-apposing metal stents has been proposed to lower the bleeding risk by preventing tissue abrasion against the stent flanges. We present a case of an 83 year-old male who had previously undergone uncomplicated endoscopic ultrasound-guided cholecystoduodenostomy with this technique. Six months later, he presented with upper gastrointestinal bleeding due to a duodenal pressure ulcer from the coaxial 10-Fr double-pigtail stent originally employed to prevent such bleeding. The 10-Fr stent was replaced with two 7-Fr stents whose increased flexibility and distribution of pressure across multiple points of contact with the duodenal wall was theorized to reduce the likelihood of erosion or perforation. Following the procedure, the patient's clinical course improved significantly with complete resolution of his symptoms of choledocholithiasis and cholecystitis. While 10-Fr double-pigtail stents are generally preferred for this indication due to their stiffness that reduces out-migration, use of more flexible 7-Fr stents may be advisable in thin-walled structures such as the duodenum.

A Case of Pneumothorax Ex Vacuo Associated with COVID-19.

Pneumothorax is a known complication of coronavirus disease 2019 (COVID-19). The concept of pneumothorax ex vacuo has also been proposed to describe pneumothorax that occurs after malignant pleural effusion drainage. Herein, we present the case of a 67-year-old woman who had abdominal distension for 2 months. A detailed examination led to the suspicion of an ovarian tumor and revealed an accumulation of pleural effusion and ascitic fluid. Thoracentesis was performed, raising the suspicion of metastasis of high-grade serous carcinoma arising from the ovary. An ovarian biopsy was scheduled to select subsequent pharmacotherapy, and a drain was inserted preoperatively into the left thoracic cavity. Thereafter, a polymerase chain reaction analysis revealed that the patient was positive for COVID-19. Thus, the surgery was postponed. After the thoracic cavity drain was removed, pneumothorax occurred, and mediastinal and subcutaneous emphysema was observed. Thoracic cavity drains were then placed again. The patient's condition was conservatively relieved without surgery. This patient may have developed pneumothorax ex vacuo during the course of a COVID-19 infection. Since chronic inflammation in the thoracic cavity is involved in the onset of pneumothorax ex vacuo, careful consideration is required for the thoracic cavity drainage of malignant pleural effusion and other fluid retention.

Ventilatory Failure And Pulmonary Embolism In Covid-19 Requiring Enhanced Venous Drainage For Extracorporeal Membrane Oxygenation.

COVID-19 infection manifests as a spectrum of respiratory and vascular complications, including acute respiratory distress syndrome (ARDS) and pulmonary embolism. Herein, we describe a case of a healthy young male who presented with ARDS refractory to mechanical ventilation and concomitant bilateral pulmonary emboli managed with extracorporeal membrane oxygenation (ECMO) and embolectomy. The embolectomy and initial veno-venous ECMO configuration failed to correct the patient's hypoxemia despite maximal flows. This was thought to be due to a high-output state secondary to vasodilatory shock preventing adequate drainage from the existing single drainage ECMO cannulation, following which a second venous cannula was placed to form a unique veno-veno-venous ECMO circuit that resolved the persistent hypoxemia. The case underscores the importance of identifying embolic events and vasodilatory shock in COVID-19 patients, both of which need to be addressed simultaneously to avoid worsening right ventricular failure (via both mechanical and hypoxia-driven pathways) and the resulting veno-arterial ECMO along with its associated complications.

Inversed probability case-control analysis of operative burr hole evacuation versus subdural evacuating port system for chronic subdural hematomas: Clinical and economic outcomes.

INTRODUCTION: There are multiple treatments for a chronic subdural hematoma, a significant cause of neurosurgical morbidity that cost the healthcare system $5B in 2007, but few generalizable prospective studies. The purpose of this study was to examine outcomes of bedside Subdural Evacuation Port System (SEPS) placement as compared to operating room burr hole evacuation (BHE) to acquire data to support a randomized trial. METHODS: All procedures were performed in a single institution between 2011 and 2019. Patients were included if > 18 years of age, had chronic subdural hematoma, and were treated by SEPS or BHE. Patients with prior neurosurgical history, mass lesions or bilateral hematomas were excluded. Patients who met inclusion for SEPS (n = 55) or BHE (n = 105). Samples were propensity matched to account for variability. Non-inferiority tests compared outcomes. Cost data was obtained through billable charges. RESULTS: Patients with multiple comorbidities were more likely to undergo SEPS drainage. Noninferiority tests reported no statistically significant evidence to suggest SEPS drains were worse in reoperation-rate (18% vs 9%), post-operative seizure, or functional outcome. SEPS drain placement trended towards a faster time to procedure (3 h faster; p = 0.07) but the overall hospital stay was longer (4.23 vs 5.81, p = 0.01). SEPS drain placement costs are less than BHE, but these patients had 25% higher overall hospital costs (p = 0.01) due to comorbidities and increased hospital stay.

An Adolescent With a Retropharyngeal Swelling: To Drain or Not to Drain?: Keeping a Broad Vision During the COVID-19 Pandemic.

CASE PRESENTATION: An 18-year-old patient with a history of COVID-19 (1 month previously) was admitted with malaise and complaints of a stiff neck, a left-sided cervical mass, headache, and difficulty in swallowing and breathing, which had been present for 4 days. Two days after the onset of the first symptoms, a painless skin rash on the legs, arms, palms of both hands, and soles of both feet developed. Despite 2 days of treatment with antibiotics (amoxicillin/clavulanic acid, 500/125 mg three times daily orally), symptoms progressed. On presentation, the patient was alert and oriented, there were no neurologic disorders, and all symptoms related to the recent COVID-19 infection had subsided. His medical history was negative for sexually transmitted diseases, and the patient had received all vaccines except for meningococcus and COVID-19.

Percutaneous biopsy and drainage of the pancreas.

Percutaneous pancreatic interventions performed by abdominal radiologists play important diagnostic and therapeutic roles in the management of a wide range of pancreatic pathology. While often performed with endoscopy, pancreatic mass biopsy obtained via a percutaneous approach may serve as the only feasible option for diagnosis in patients with post-surgical anatomy, severe cardiopulmonary conditions, or prior non-diagnostic endoscopic attempts. Biopsy of pancreatic transplants are commonly performed percutaneously due to inaccessible location of the allograft by endoscopy, usually in the right lower quadrant or pelvis. Percutaneous drainage of collections in acute pancreatitis is primarily indicated for infection with clinical deterioration and may be performed alone or in combination with endoscopic drainage. Post-surgical pancreatic collections related to pancreatic duct fistula or leak also often warrant therapeutic percutaneous drainage. Knowledge of appropriate indications, strategies of approach, technique, and complications associated with these procedures is critical for a successful clinical practice.

Online Complex Decongestive Therapy (CDT) Initiation for Lymphoedema - A Case Study.

Lymphoedema is a chronic disease affecting millions. Standard treatment is Complex Decongestive Therapy (CDT) which entails physical interaction with a therapist to imitate the drainage of the edematous fluid along with training to continue self-care at home. We present a case study of initiating CDT totally online. The result showed that, though totally online lymphoedema care is possible, hurdles do exist. It can be an option to exercise even after the COVID period.

Modified safety techniques for transcatheter repair of superior sinus venosus defects with partial anomalous pulmonary venous drainage using a 100-mm Optimus-CVS® covered XXL stent.

We report the first use of a single 100-mm long custom-made version of the Optimus-CVS® balloon-expandable PTFE-covered XXL (15-Zig) stent (AndraTec, GmbH) to eliminate sinus venosus defect left-to-right shunt and redirect anomalous right pulmonary veins blood flow through a new walled channel to the left atrium. Anatomical feasibility and strategy decision were guided by ex-vivo procedure simulation on the patient-specific 3D printed heart model and in-vivo balloon interrogation. Modified procedural and implantation techniques are detailed. Immediate and one-month follow-up showed excellent outcomes.

Case of a Deep Neck Abscess During Treatment for COVID-19.

BACKGROUND COVID-19 is treated using antiviral and immunosuppressive drugs. Therefore, patients treated for COVID-19 may have an increased risk of secondary infection and a masked inflammatory response. We present a case of a deep neck abscess caused by pyogenic sternoclavicular arthritis during treatment for COVID-19. CASE REPORT A 55-year-old man with COVID-19 was admitted to the hospital with hypoxemia. He was then treated with remdesivir, tocilizumab, and dexamethasone and was placed in the prone position. When his condition stabilized, pain in the left shoulder appeared. There was no fever or elevation in inflammation markers, and he was administered analgesics. However, the pain worsened and redness of the left neck appeared. Plain computed tomography (CT) showed swelling of the left neck muscles. Because cellulitis was suspected, he was treated with antibiotics, but his symptoms did not improve. Three days after the plain CT, contrast-enhanced CT showed sternoclavicular arthritis, deep neck abscess, and mediastinal abscess. Therefore, an emergency incisional drainage was performed under general anesthesia. Wound cleaning and drainage were continued after surgery, and after drainage tubes were removed, the patient was discharged on postoperative day 17. CONCLUSIONS Cervical infections after COVID-19 treatment have been reported in a few cases. Particularly, deep neck abscesses require more attention since they could be fatal if not treated immediately. If a secondary infection is suspected in a patient treated with immunosuppressive drugs for COVID-19, a thorough physical examination should be performed to avoid misdiagnosis.

Abdominal drainage to prevent intra-peritoneal abscess after appendectomy for complicated appendicitis.

BACKGROUND: This is the second update of a Cochrane Review first published in 2015 and last updated in 2018. Appendectomy, the surgical removal of the appendix, is performed primarily for acute appendicitis. Patients who undergo appendectomy for complicated appendicitis, defined as gangrenous or perforated appendicitis, are more likely to suffer postoperative complications. The routine use of abdominal drainage to reduce postoperative complications after appendectomy for complicated appendicitis is controversial. OBJECTIVES: To assess the safety and efficacy of abdominal drainage to prevent intraperitoneal abscess after appendectomy (irrespective of open or laparoscopic) for complicated appendicitis; to compare the effects of different types of surgical drains; and to evaluate the optimal time for drain removal. SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (CENTRAL), Ovid MEDLINE, Ovid Embase, Web of Science, the World Health Organization International Trials Registry Platform, ClinicalTrials.gov, Chinese Biomedical Literature Database, and three trials registers on 24 February 2020, together with reference checking, citation searching, and contact with study authors to identify additional studies. SELECTION CRITERIA: We included all randomised controlled trials (RCTs) that compared abdominal drainage versus no drainage in people undergoing emergency open or laparoscopic appendectomy for complicated appendicitis. We also included RCTs that compared different types of drains and different schedules for drain removal in people undergoing appendectomy for complicated appendicitis. DATA COLLECTION AND ANALYSIS: We used standard methodological procedures expected by Cochrane. Two review authors independently identified the trials for inclusion, collected the data, and assessed the risk of bias. We used the GRADE approach to assess evidence certainty. We included intraperitoneal abscess as the primary outcome. Secondary outcomes were wound infection, morbidity, mortality, hospital stay, hospital costs, pain, and quality of life. MAIN RESULTS: Use of drain versus no drain We included six RCTs (521 participants) comparing abdominal drainage and no drainage in participants undergoing emergency open appendectomy for complicated appendicitis. The studies were conducted in North America, Asia, and Africa. The majority of participants had perforated appendicitis with local or general peritonitis. All participants received antibiotic regimens after open appendectomy. None of the trials was assessed as at low risk of bias. The evidence is very uncertain regarding the effects of abdominal drainage versus no drainage on intraperitoneal abscess at 30 days (risk ratio (RR) 1.23, 95% confidence interval (CI) 0.47 to 3.21; 5 RCTs; 453 participants; very low-certainty evidence) or wound infection at 30 days (RR 2.01, 95% CI 0.88 to 4.56; 5 RCTs; 478 participants; very low-certainty evidence). There were seven deaths in the drainage group (N = 183) compared to one in the no-drainage group (N = 180), equating to an increase in the risk of 30-day mortality from 0.6% to 2.7% (Peto odds ratio 4.88, 95% CI 1.18 to 20.09; 4 RCTs; 363 participants; low-certainty evidence). Abdominal drainage may increase 30-day overall complication rate (morbidity; RR 6.67, 95% CI 2.13 to 20.87; 1 RCT; 90 participants; low-certainty evidence) and hospital stay by 2.17 days (95% CI 1.76 to 2.58; 3 RCTs; 298 participants; low-certainty evidence) compared to no drainage. The outcomes hospital costs, pain, and quality of life were not reported in any of the included studies. There were no RCTs comparing the use of drain versus no drain in participants undergoing emergency laparoscopic appendectomy for complicated appendicitis. Open drain versus closed drain There were no RCTs comparing open drain versus closed drain for complicated appendicitis. Early versus late drain removal There were no RCTs comparing early versus late drain removal for complicated appendicitis. AUTHORS' CONCLUSIONS: The certainty of the currently available evidence is low to very low. The effect of abdominal drainage on the prevention of intraperitoneal abscess or wound infection after open appendectomy is uncertain for patients with complicated appendicitis. The increased rates for overall complication rate and hospital stay for the drainage group compared to the no-drainage group are based on low-certainty evidence. Consequently, there is no evidence for any clinical improvement with the use of abdominal drainage in patients undergoing open appendectomy for complicated appendicitis. The increased risk of mortality with drainage comes from eight deaths observed in just under 400 recruited participants. Larger studies are needed to more reliably determine the effects of drainage on morbidity and mortality outcomes.

Novel method for left ventricular unloading utilizing percutaneous pulmonary artery drainage in cardiorespiratory failure due to COVID-19 infection.

Left ventricular (LV) unloading is an important concept in patients undergoing peripheral venoarterial extracorporeal membrane oxygenation (VA-ECMO). We present a case of a 32-year-old male in acute cardiorespiratory collapse due to coronavirus disease (COVID-19) who underwent VA-ECMO cannulation in the setting of cardiogenic shock and acute respiratory distress syndrome. Due to inability to utilize percutaneous LV assist device (pLVAD) for LV unloading due to small end diastolic dimension, alternative strategies were explored. A traditionally utilized right ventricular support device, the ProTek Duo (TandemLife, Pittsburgh, PA), was utilized to drain the pulmonary artery, leading to improvement in parameters for cardiogenic shock. To our knowledge, this is the first case in which a ProTek Duo has been utilized in conjunction with VA-ECMO to provide LV unloading in support of a patient in cardiogenic shock. This method can be employed in future challenging situations where pLVAD is not feasible.

Gastrointestinal complications (gangrene or perforation) after corona virus disease 2019 - A series of ten patients.

During the recent second wave of corona virus disease 2019 (COVID-19) pandemic in India, we managed a series of gastrointestinal complications in patients with COVID-19. We aim to highlight the key presentation and clinical course and emphasize the lessons we learnt from our series of such patients. A case review of ten consecutive patients with either bowel gangrene or perforation who were managed at our centre from March 20, 2021 to June 10, 2021. Clinical-demographic details, possible etiology, radiological findings, management and outcomes have been described. Of the 10 patients, 2 presented with bowel gangrene and 8 with perforation. In our series, all these patients were diagnosed with the help of computed tomography (CT) abdomen during the 3rd week after diagnosis of COVID-19. All had received steroid medication. Both patients with bowel gangrene and 4 of 8 patients with perforation underwent surgery, while 4 were managed non-operatively. Barring one patient, all the operated patients succumbed within 5 days of surgery after rapid clinical deterioration. Non-operative management in selected patients with perforation including placement of percutaneous drains, bowel rest and antibiotics was successful. Emergency surgery for COVID-19 related intestinal gangrene or perforation was associated with high mortality in our series. Non-operative management which avoids the added stress of a major emergency surgery particularly in patients just recovering from COVID-19 may be considered in stable patients in whom perforation appears to be contained.

Effect of External Ventricular Drain Tunnel Length on Cerebrospinal Fluid Infection Rates-A Bayesian Network Meta-Analysis.

BACKGROUND: External ventricular drain (EVD)-associated cerebrospinal fluid infection (EACI) remains a major complication associated with EVD. Length of EVD tunnel, an overlooked but modifiable factor, can be associated with increased risk of EACI. The aim of this study is to find the tunnel length associated with least chances of EACI by performing a network meta-analysis. METHODS: A comprehensive search of different databases was performed to retrieve studies that studied the rates of EACI with different EVD tunnel lengths and a Bayesian network meta-analysis was performed. RESULTS: Six studies met the inclusion criteria and were included in the network meta-analysis. With 0 cm tunnel length as reference, the odds ratio (OR) for developing EACI was minimum for tunnel length 5-10 cm (OR, 0.027). It was followed by tunnel length of 5 cm (OR, 0.060) and 10 cm (OR, 0.075). The surface under the cumulative ranking curve plot showed that the probability of the tunnel length 5-10 cm (ranked first), 5 cm (ranked second), and 10 cm (ranked third) for being the best EVD tunnel length was found to be 86%, 64%, and 61%, respectively. CONCLUSIONS: The length for which an EVD is tunneled may have an impact on the rate of EACI. Our network meta-analyses showed that the tunnel length of 5-10 cm was associated with the lowest rates of EACI, with 86% probability of being the best EVD tunnel length. The probability of a patient with 5-10 cm EVD length developing EACI was 2.7% compared with zero tunnel length.

Indwelling Pleural Catheters for Malignant Pleural Effusion: A Time for Action.

Malignant pleural effusion (MPE) resulting from metastatic spread to the pleura frequently occurs in patients with primary lung, breast, hematological, gastrointestinal, and gynecological cancers. These effusions tend to reaccumulate quickly, and the patient requires increasingly frequent thoracentesis. An indwelling pleural catheter allows for dramatic improvement in quality of life as the patient has the power to ease her/his own suffering by draining the effusion at home when shortness of breath and/or chest pain intensifies. Patients with MPE need home healthcare support to address symptom management related to complications of advanced metastatic cancer and antineoplasm treatment regimens. The financial obstacles for the home healthcare agency are explored by using agency supply costs, per visit costs, and the patient-driven groupings reimbursement mode grouper to estimate reimbursement. Care for a home healthcare patient with MPE costs Medicare approximately $64.50 per day, markedly less than costs for hospitalization and outpatient thoracentesis. Unfortunately, agencies must absorb the cost of vacuum drainage bottles. Whereas a small positive balance of $291 was estimated for the first 30-day posthospital episode, losses were estimated at $1,185 to $1,633 for subsequent 30-day episodes. Absorbing these costs has become extremely difficult as home healthcare agencies are experiencing unprecedented COVID-19 infection control and staffing-related costs.

Recurrent appendicitis following successful drainage of appendicular abscess in adult without interval appendectomy during COVID-19. Prospective cohort study.

BACKGROUND: COVID-19 infection is a global pandemic that affected routine health services and made patients fear to consult for medical health problems, even acute abdominal pain. Subsequently, the incidence of complicated appendicitis increased during the Covid-19 pandemic. This study aimed to evaluate recurrent appendicitis after successful drainage of appendicular abscess during COVID-19. MATERIAL AND METHODS: A prospective cohort study conducted in the surgical emergency units of our Universities' Hospitals between March 15, 2020 to August 15, 2020 including patients who were admitted with the diagnosis of an appendicular abscess and who underwent open or radiological drainage. Main outcomes included incidence, severity, and risk factors of recurrent appendicitis in patients without interval appendectomy. RESULTS: A total of 316 patients were included for analysis. The mean age of the patients was 37 years (SD ± 13). About two-thirds of patients were males (60.1%). More than one-third (39.6%) had co-morbidities; type 2 diabetes mellitus (T2DM) (22.5%) and hypertension (17.1%) were the most frequent. Approximately one quarter (25.6%) had confirmed COVID 19 infection. About one-third of the patients (30.4%) had recurrent appendicitis. More than half of them (56.3%) showed recurrence after three months, and 43.8% of patients showed recurrence in the first three months. The most frequent grade was grade I (63.5%). Most patients (77.1%) underwent open surgery. Age, T2DM, hypertension, COVID-19 infection and abscess size >3 cm were significantly risking predictors for recurrent appendicitis. CONCLUSIONS: Interval appendectomy is suggested to prevent 56.3% of recurrent appendicitis that occurs after 3 months. We recommend performing interval appendectomy in older age, people with diabetes, COVID-19 infected, and abscesses more than 3 cm in diameter. RESEARCH QUESTION: Is interval appendectomy preventing a high incidence of recurrent appendicitis after successful drainage of appendicular abscess during COVID-19 pandemic?

Giant Idiopathic Lymphocele 18 Years After Kidney Transplantation, Treated Using Lymphatic Embolization With Lipiodol: Report of a Rare Case.

Kidney transplant is the best therapeutic option for patients with end-stage kidney disease. However, kidney transplant is not exempt from postoperative complications. One of the most frequent urological complications is lymphocele, which can appearin up to 20% of patients. Lymphocele most often appears during the first month after surgery. However, its appearance after the first yearis completely infrequent. Here, we report a case of a giant idiopathic lymphocele 18 years after kidney transplant and its resolution with lymphatic embolization.The patient, a 34-year-old man who received a deceased-donor kidney transplant in 2002, had presented with no complications until the lymphocele was diagnosed. The lymphocele presented as a voluminous organ-compressing mass. A percutaneous drainage was placed, and 3600 cm3 of lymphatic fluidwere drained.Afterthat, 800 cm3 continued to leak every day. An intranodal lymphography and lymphatic embolization with Lipiodol Ultra-Fluide (Guerbet Australia) were performed, owing to the high amount of leakage. At 50 days after embolization, an ultrasonograph showed no fluid collections, so the percutaneous catheter was removed. In most patients, the treatment ofthe lymphocele after kidney transplant is frequently conservative. However,for patients whose situation cannot be resolved spontaneously, there are few therapeutic choices. As described here, intranodal lymphatic embolization is a mini-invasive option, with a success rate of up to 80%, and should be offered as the first approach.
