A 91-year-old woman was brought to our hospital with altered consciousness. Blood tests showed an increased ammonia level of 468 μg/dL and a normal liver function. Chest computed tomography showed massive right pleural effusion with loculation. We immediately performed chest drainage using two drainage tubes. The pleural effusate pH was 8.5. We diagnosed her with right empyema leading to hyperammonemia and initiated ampicillin/sulbactam therapy. However, she developed progressive renal failure and died on the third day. Empyema caused by urease-producing bacteria can lead to hyperammonemia. This is the first report of hyperammonemia due to empyema in the English literature.

Randomized Controlled Trial
IMPORTANCE
Intraventricular lavage has been proposed as a minimally invasive method to evacuate intraventricular hemorrhage. There is little evidence to support its use.
OBJECTIVE
To evaluate the safety and potential efficacy of intraventricular lavage treatment of intraventricular hemorrhage.
DESIGN, SETTING, AND PARTICIPANTS
This single-blinded, controlled, investigator-initiated 1:1 randomized clinical trial was conducted at Aarhus University Hospital and Odense University Hospital in Denmark from January 13, 2022, to November 24, 2022. Follow-up duration was 90 days. The trial was set to include 58 patients with intraventricular hemorrhage. Prespecified interim analysis was performed for the first 20 participants. Data were analyzed from February to April 2023.
INTERVENTIONS
Participants were randomized to receive either intraventricular lavage or standard drainage.
MAIN OUTCOMES AND MEASURES
The main outcome was risk of catheter occlusions. Additional safety outcomes were catheter-related infections and procedure time, length of stay at the intensive care unit, duration of treatment, and 30-day mortality. The main outcome of the prespecified interim analysis was risk of severe adverse events. Efficacy outcomes were hematoma clearance, functional outcome, overall survival, and shunt dependency.
RESULTS
A total of 21 participants (median [IQR] age, 67 [59-82] years; 14 [66%] male) were enrolled, with 11 participants randomized to intraventricular lavage and 10 participants randomized to standard drainage; 20 participants (95%) had secondary intraventricular hemorrhage. The median (IQR) Graeb score was 9 (5-11), and the median (IQR) Glasgow Coma Scale score was 6.5 (4-8). The study was terminated early due to a significantly increased risk of severe adverse events associated with intraventricular lavage at interim analysis (risk difference for control vs intervention, 0.43; 95% CI, 0.06-0.81; P = .04; incidence rate ratio for control vs intervention, 6.0; 95% CI, 1.38-26.1; P = .01). The rate of catheter occlusion was higher for intraventricular lavage compared with drainage (6 of 16 patients [38%] vs 2 of 13 patients [7%]; hazard ratio, 4.4 [95% CI, 0.6-31.2]; P = .14), which met the prespecified α = .20 level. Median (IQR) procedure time for catheter placement was 53.5 (33-75) minutes for intraventricular lavage vs 12 (4-20) minutes for control (P < .001).
CONCLUSIONS AND RELEVANCE
This randomized clinical trial of intraventricular lavage vs standard drainage found that intraventricular lavage was encumbered with a significantly increased number of severe adverse events. Caution is recommended when using the device to ensure patient safety.

Meta-Analysis Review
Chronic subdural hematoma (cSDH) is a common neurosurgical condition that can cause severe morbidity and mortality. cSDH recurs after surgical evacuation in 5-30% of patients, but drains may help reduce this risk. We aimed to investigate the effect of drainage versus no drainage on the rates of recurrence and mortality, as well as the clinical outcomes of cSDH. Following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, we searched four electronic databases (PubMed, Cochrane Library, Scopus, and Web of Science) to identify eligible studies reported up to June 2022. Using Review Manager software, we reported four primary outcomes as odds ratios (ORs) and confidence intervals (CIs). The meta-analysis included a total of 10 studies with 1961 patients. The use of drainage was found to be significantly more effective than non-drainage in reducing the "mortality rate" (OR = 0.65, 95% CI 0.43 to 0.97; P = 0.04), the "recurrence rate" (OR = 0.39, 95% CI 0.28 to 0.55; P < 0.00001), and occurrence of "gross focal neurological deficit" (OR = 0.58, 95% CI 0.37 to 0.89; P = 0.01). No significant difference was found in the occurrence of a Glasgow Coma Scale score of 15 (OR = 1.21, 95% CI 0.84 to 1.76; P = 0.30). The use of drains after burr-hole irrigation reduces the recurrence, mortality, and gross focal neurological deficit rates of chronic subdural hematomas.

Meta-Analysis
Safety and efficacy of lumen-apposing metal stents and double-pigtail plastic stents for endoscopic ultrasound-guided drainage of walled-off necrosis; a systematic review and meta-analysis.
BACKGROUND
Patients with walled-off necrosis (WON) are still challenging to treat safely and effectively. Recently, double-pigtail plastic stents (DPS), bi-flanged metallic stents (BFMS), and lumen-apposing metal stents (LAMS) have been employed with endoscopic ultrasound-guided (EUS-guided) drainage. However, there is little solid evidence to support the effectiveness and safety of using stents. This study aims to compare the outcomes of the LAMS and the PS.
METHOD
Till July 2022, a thorough database search was done, and studies that met the criteria were chosen. By using the RevMan software, the technical and clinical success and other secondary outcomes were calculated. Subgroup analysis was performed between the LAMS and the BFMS.
RESULTS
Fifteen studies (two randomized controlled trials and thirteen observational) with 687 patients receiving metal stents and 771 patients receiving plastic stents were selected for final analysis. There was no significant risk of bias or publication bias. The odds ratios (OR) for technical and clinical success were 0.36 (95% confidence interval (95% CI) 0.08, 1.52) and 2.26 (95%CI 1.62, 3.15), respectively. The OR for overall adverse events was 0.74 (95% CI 0.41, 1.34). In subgroup analysis, the LAMS and the BFMS showed the same outcomes.
CONCLUSION
Compared to DPS, LAMS had better clinical outcomes and fewer side effects when treating patients with WON.

BACKGROUND
Anastomotic leakage and postoperative pancreatic fistula (POPF) may occur after pancreatic head resection, also in the setting of pancreato-gastric reconstruction. For adequate complication management, a variety of non-standardized treatments are available. Still, data on clinical evaluation of endoscopic methods remain scarce. Based on our interdisciplinary experience on endoscopic treatment of retro-gastric fluid collections after left-sided pancreatectomies, we developed an innovative endoscopic concept with internal peri-anastomotic stent placement for patients with anastomotic leakage and/or peri-anastomotic fluid collection.
METHODS
Over the period of 6 years (2015-2020) we retrospectively evaluated 531 patients after pancreatic head resections at the Department of Surgery, Charité-Unversitätsmedizin Berlin. Of these, 403 received reconstruction via pancreatogastrostomy. We identified 110 patients (27.3%) with anastomotic leakage and/or peri-anastomotic fluid collection and could define four treatment groups which received either conservative treatment (C), percutaneous drainage (PD), endoscopic drainage (ED), and/or re-operation (OP). Patients were grouped in a step-up approach for descriptive analyses and in a stratified, decision-based algorithm for comparative analyses. The study's primary endpoints were hospitalization (length of hospital stay) and clinical success (treatment success rate, primary/secondary resolution).
RESULTS
We characterized an institutional, post-operative cohort with heterogenous complication management following pancreato-gastric reconstruction. The majority of patients needed interventional treatments (n = 92, 83.6%). Of these, close to one-third (n = 32, 29.1%) were treated with endoscopy-guided, peri-anastomotic pigtail stents for internal drainage as either primary, secondary and/or tertiary treatment modality. Following a decision-based algorithm, we could discriminate superior primary-(77,8% vs 53.7%) and secondary success rates (85.7% vs 68.4%) as well as earlier primary resolutions (11.4 days, 95%CI (5.75-17.13) vs 37.4 days, 95%CI (27.2-47.5)] in patients receiving an endoscopic compared to percutaneous management.
CONCLUSION
This study underscores the importance of endoscopy-guided approaches for adequate treatment of anastomotic leakage and/or peri-anastomotic fluid collections after pancreatoduodenectomy. We herein report a novel, interdisciplinary concept for internal drainage in the setting of pancreato-gastric reconstruction.

BACKGROUND
Perianal abscesses require immediate incision and drainage (I&D). However, prompt bedside drainage is controversial as it may compromise exposure and thorough anal examination.
OBJECTIVES
To examine outcomes of bedside I&D of perianal abscesses in the emergency department (ED) vs. the operating room (OR).
METHODS
We conducted a retrospective review of all patients presented to the ED with a perianal abscesses between January 2018 and March 2020. Patients with Crohn's disease, horseshoe or recurrent abscesses were excluded.
RESULTS
The study comprised 248 patients; 151 (60.89%) underwent I&D in the OR and 97 (39.11%) in the ED. Patients elected to bedside I&D had smaller abscess sizes (P = 0.01), presented with no fever, and had lower rates of inflammatory markers. The interval time from diagnosis to intervention was significantly shorter among the bedside I&D group 2.13 ± 2.34 hours vs. 10.41 ± 8.48 hours (P < 0.001). Of patients who underwent I&D in the OR, 7.3% had synchronous fistulas, whereas none at bedside had (P = 0.007). At median follow-up of 24 months, recurrence rate of abscess and fistula formation in patients treated in the ED were 11.3% and 6.2%, respectively, vs. 19.9% and 15.23% (P = 0.023, 0.006). Fever (OR 5.71, P = 0.005) and abscess size (OR 1.7, P = 0.026) at initial presentation were risk factors for late fistula formation.
CONCLUSIONS
Bedside I&D significantly shortens waiting time and does not increase the rates of long-term complications in patients with small primary perianal abscesses.

INTRODUCTION-AIM
Tuberculous pneumothorax (TP) is a serious complication of cavitary pulmonary tuberculosis. The aim of this study was to identify TP drainage characteristics and difficulties.
METHODS
This was a retrospective multicenter study of patients hospitalized for TP between 1999 and 2021 in three hospitals from Tunis (Tunisia): Abderahmen Mami, La Rabta, and Charles Nicolle. Clinical, biological, radiological, therapeutic and evolutionary data were collected.
RESULTS
Seventy-three patients were enrolled. The mean±standard-deviation (SD) of age was 37±17 years. The sex ratio was 3.3. TP was isolated in 39 patients (53.4%) and was associated with a purulent effusion in 34 patients (46.6%). It was bilateral in three patients (4.1%). Chest drainage was indicated in 67 patients (91.7%). It was performed with a chest drain in 61 cases, with a pleuro-catheter in one case, and with a pleuro-catheter then a chest drain in five cases. The mean±SD (ranges) duration of drainage was 43±39 (3-175) days. Drainage was prolonged in 36 cases (53.7%). The duration of drainage for pyopneumothorax was significantly longer than for isolated TP (p=0.04). The mean±SD (ranges) number of drains inserted in each patient was 2.02 ±1 (1-7) drains. Spontaneous drain fall was observed in 13 patients. Drainage failure was observed in 16 patients, and was more frequent in cases of pyopneumothorax (p=0.039). Recurrence of pneumothorax was noted in nine patients (13.4%).
CONCLUSION
The drainage of TP is often extended and requires the use of multiple drains. It is associated with several complications. Failure of thoracic drainage is not negligible.

Review
BACKGROUND
Peritonsillar abscess is a localised infection in the peritonsillar space. Pus from the abscess can contain anaerobes. Many clinicians prescribe metronidazole in addition to penicillin, but evidence to support this is limited. This review assessed the evidence of benefit of metronidazole for the treatment of peritonsillar abscess.
METHODS
A systematic review was conducted of the literature and databases including Ovid Medline, Ovid Embase, PubMed and Cochrane library. Search terms included all variations of peritonsillar abscess, penicillin and metronidazole.
RESULTS
Three randomised, control trials were included. All studies assessed the clinical outcomes after treatment for peritonsillar abscess, including recurrence rate, length of hospital stay and symptom improvement. There was no evidence to suggest additional benefit with metronidazole, with studies suggesting increased side effects.
CONCLUSION
Evidence does not support the addition of metronidazole in first-line management of peritonsillar abscess. Further trials to establish optimum dose and duration schedules of oral phenoxymethylpenicillin would benefit clinical practice.

BACKGROUND
The aim of this multicentre prospective audit was to describe the current practice in the management of mastitis and breast abscesses in the UK and Ireland, with a specific focus on rates of surgical intervention.
METHODS
This audit was conducted in two phases from August 2020 to August 2021; a phase 1 practice survey and a phase 2 prospective audit. Primary outcome measurements for phase 2 included patient management pathway characteristics and treatment type (medical/radiological/surgical).
RESULTS
A total of 69 hospitals participated in phase 2 (1312 patients). The key findings were a high overall rate of incision and drainage (21.0 per cent) and a lower than anticipated proportion of ultrasound-guided aspiration of breast abscesses (61.0 per cent). Significant variations were observed regarding the rate of incision and drainage (range 0-100 per cent; P < 0.001) and the rate of needle aspiration (range 12.5-100 per cent; P < 0.001) between individual units. Overall, 22.5 per cent of patients were admitted for inpatient treatment, out of whom which 72.9 per cent were commenced on intravenous antibiotics. The odds of undergoing incision and drainage for a breast abscess or being admitted for inpatient treatment were significantly higher if patients presented at the weekend compared with a weekday (P ≤ 0.023). Breast specialists reviewed 40.9 per cent of all patients directly, despite the majority of patients (74.2 per cent) presenting within working hours on weekdays.
CONCLUSIONS
Variation in practice exists in the management of mastitis and breast abscesses, with high rates of incision and drainage in certain regions of the UK. There is an urgent need for a national best-practice toolbox to minimize practice variation and standardize patient care.

Meta-Analysis
BACKGROUND
Breast abscess is a common and intractable clinical condition and the use of needle aspiration (NA) or incision and drainage (ID) in treatment is controversial. This meta-analysis aimed to systematically compare the clinical effectiveness of NA and ID in treating breast abscesses.
METHODS
The Web of Science, ScienceDirect, PubMed, Cochrane Library, EMBASE, China National Knowledge Infrastructure, and Wanfang Data were searched for randomized controlled trials (RCTs) published from inception to January 7, 2022. The ROB-2 tool assessed risk of bias; the GRADE methodology rated certainty in outcomes; and Stata 16.0 performed data analyses.
RESULTS
Nine RCTs were included, including 703 patients. The results showed there was no significant difference in cure rate between the two groups (relative risk [RR] = 0.96, 95% confidence interval [CI] [0.86, 1.07]; = .469), and after subgroup analysis, we found that it was not related to the use of ultrasound guidance or not. There was no significant difference in the recurrence rate (RR = 0.68, 95% CI [0.35, 1.30]; = .241). Furthermore, the NA group was associated with shorter healing time (weighted mean differences = -11.02, 95% CI [-15.14, -6.90]; < .001), lower incidence of breast fistula (RR = 0.21, 95% CI [0.06, 0.72]; = .013), lower interrupted breastfeeding rate (RR = 0.28, 95% CI [0.20, 0.39]; < .001), and higher satisfaction rate of appearance (RR = 1.51, 95% CI [1.03-2.21]; = .035).
CONCLUSION
NA has better advantages in terms of healing time, avoidance of breast fistula, continuous breastfeeding, and patient satisfaction. Although NA and ID have similar cure and recurrence rates, NA, with or without ultrasound guidance, could be used as a first-line treatment for breast abscesses. Patients with large volumes, multicompartmental abscesses, or those who have been ineffective against multiple NA, should be considered for ID.KEY MESSAGESBreast abscess is a common and intractable clinical condition in general surgery.Compared with ID for breast abscesses, NA has better advantages in terms of healing time, avoidance of breast fistula, continuous breastfeeding, and patient satisfaction and could be used as a first-line treatment for breast abscesses.Patients with large volumes, multicompartmental abscesses, or those who have been ineffective against multiple NA, should be considered for ID.
