appendiceal abscess

The incidence of appendiceal stump leakage (ASL) is extremely low and heterogeneous, which has been reported to be approximately 0.5%-1.0%. It is a catastrophic complication with high mortality rate despite its low morbidity. Once it occurs, it will put the doctor in a passive position because dealing with the leakage is much more cumbersome than appendectomy. We extensively reviewed the literature on ASL, focusing on the management and prognosis. Unsurprisingly, all of the physicians advocated extended resection, which apparently gave them sufficient confidence...

BACKGROUND: This retrospective study aimed to combine the clinical signs, laboratory values, and ultrasound images of 199 children with acute appendicitis in order to create a new predictive score for complicated appendicitis in children. METHODS: The study included children who had clinical examination of abdominal pain (description of pain, anorexia, body temperature, nausea or vomiting, duration of symptoms), laboratory findings on admission (white blood cell, platelets, neutrophils, C-reactive protein), preoperative abdominal ultrasound, and histopathological report after an operation for appendicitis in their records during the period from January 2016 to February 2022...

PURPOSE: Appendiceal stump leak rate after laparoscopic appendectomy is extremely low. Various methods are used to close the appendiceal stump. This study aimed to compare the outcome of three appendiceal stump closure methods. METHODS: A retrospective study comparing stump closure methods and postoperative outcomes was conducted from January 2018 to June 2020. Patient data included demographics, pre-operative data, surgical technique, findings, and postoperative complications...

Amyand's hernia is a rare clinical entity, defined as an inguinal hernia containing the appendix. Giant inguinoscrotal hernia is also a rare clinical finding that presents major operative dilemmas due to the loss of abdominal domain. Here, we report a case of a 57-year-old male who presented with a giant irreducible right inguinoscrotal hernia and obstructive symptoms. The patient underwent an emergency open right inguinal hernia repair, where an Amyand's hernia was identified. The hernia contained an inflamed appendix and associated abscess, caecum, terminal ileum, and descending colon...

Background: Post-operative organ/space infection (OSI) is associated with prolonged hospital stay or re-admission. Here, we explore the predictors for OSI in pediatric patients after appendectomy. Patients and Methods: Among post-appendectomy pateints, the OSI was reviewed. A multicenter case control study was conducted to explore the risk factors for OSI among pediatric patients with appendicitis after appendectomy between January 2009 and December 2019. The potential risk factors associated with OSI were explored using multivariable logistic regression methods...

Bilioenteric fistulae are rare and difficult to manage complications of chronic cholecystitis. While cholecystoduodenal and cholecystocolic fistulae are more common, a cholecystoappendiceal fistula is an extremely rare finding. We report the presentation and operative management of a 59-year-old male with cholecystoappendiceal fistula and associated abscess in the gallbladder fossa. The patient was appropriately resuscitated, the abscess drained by interventional radiology, and after a complete workup, underwent a laparoscopic appendectomy and cholecystectomy...

Preoperative prediction of complicated appendicitis is challenging, and many clinical tools are developed to predict complicated appendicitis. This study evaluated whether a supervised learning method can recognize complicated appendicitis in emergency department (ED). Consecutive patients with acute appendicitis presenting to the ED were enrolled and included into training and testing datasets at a ratio of 70:30. The multilayer perceptron artificial neural network (ANN) models were trained to perform binary outcome classification between uncomplicated and complicated acute appendicitis...

BACKGROUND: During the Coronavirus disease 2019 (COVID-19) pandemic, a protocol was adopted by our department on antibiotics treatment for Acute Uncomplicated Appendicitis (AUA). Our study aimed to determine the feasibility and safety of non-operative treatment (NOT), compared to upfront laparoscopic appendectomy (LA), for AUA in children during the pandemic. METHOD: Our prospective comparative study was conducted from May 1, 2020 to January 31, 2021. Patient selection criteria included: age ≥5 years, abdominal pain duration ≤48 h, ultrasound (US)/Computered Tomography scan confirmation of AUA, US appendiceal diameter 6-11 mm with no features of perforation/abscess collection and no faecolith...

BACKGROUND: Gastric carcinoma is one of the most frequent malignancies worldwide. Gastric cancer metastasis to the appendix is uncommon in incidence, and has been rarely described in acute-appendicitis-related literature reviews. In this presented case, we have reported a rare case of appendiceal phlegmon, due to a diagnosis of metastatic gastric adenocarcinoma with uncommon symptoms. CASE PRESENTATION: A 79-year-old Caucasian male presented to the emergency department with history of weakness, anorexia, lethargy, and mood changes for 2 months...

Despite an uncommon condition, the clinical management of phlegmon appendicitis (retention of the intra-abdominal appendiceal abscess) is still controversial, and probiotics might be partly helpful. Then, the retained ligated cecal appendage (without gut obstruction) with or without oral Lacticaseibacillus rhamnosus dfa1 (started at 4 days prior to the surgery) was used as a representative model. At 5 days post-surgery, the cecal-ligated mice demonstrated weight loss, soft stool, gut barrier defect (leaky gut using FITC-dextran assay), fecal dysbiosis (increased Proteobacteria with reduced bacterial diversity), bacteremia, elevated serum cytokines, and spleen apoptosis without kidney and liver damage...

BACKGROUND: Seminal vesicle abscess (SVA) is the manifestation of a relatively rare urinary system infection. In response to urinary system inflammation, an abscess forms in special locations. However, acute diffuse peritonitis (ADP) induced by SVA is unusual. CASE SUMMARY: We report a case of a left SVA in a male patient complicated with pelvic abscess, ADP, multiple organ dysfunction syndrome, infectious shock, bacteremia, and acute appendiceal extraserous suppurative inflammation as a result of a long-term indwelling urinary catheter...

The appendix is a vermiform-like organ that extends from the cecum and has been thought of as having a rudimentary immunologic function. However, the appendix can become distended and mucus-filled, classifying it as a mucocele appendix. Mucoceles can be found in various locations in the body, including the colon and the appendix, and have malignancy potential. We report a case of a 48-year-old male that presented to the ED with a history of two days of abdominal pain. Upon arriving at the ED, he had a CT scan showing a 9...

A 70-year-old woman underwent conservative treatment for abscess-forming appendicitis. A contrast-enhanced abdominal computed tomography(CT)revealed a cystic lesion at the appendiceal base while the abscess had disappeared posttreatment. With the diagnosis of a low-grade appendiceal mucinous neoplasm(LAMN), a laparoscopic-assisted ileocolic resection was performed. The appendix was distended with mucus in the lumen. Histopathological examination showed that the tumor cells were more atypical than that of low-grade appendiceal mucinous neoplasm...

BACKGROUND: The distinction between complicated and uncomplicated appendicitis is very important for the selection of the treatment method. PURPOSE: To investigate the sensitivity and specificity of computed tomography (CT) in differentiating between complicated and uncomplicated appendicitis to demonstrate that false negativity in differentiating these cases can be reduced when CT findings are incorporated into the clinical evaluation of patients. MATERIAL AND METHODS: All patients aged ≥18 years who underwent appendectomy at Malatya Training and Research Hospital in 2020 and 2021 were retrospectively screened...

Background Appendicitis is a common reason for hospitalization. Rarely do people with acute appendicitis have an appendiceal mass called an abscesses or inflamed phlegmon. The goal of this study was to determine the prevalence of different appendiceal tumors including neuroendocrine tumors, adenocarcinoma, carcinoid, and mucinous and evaluate patient demographic data (e.g., age and gender) at a major tertiary care center in Riyadh, Saudi Arabia. Materials and methods We conducted a cross-sectional analytical review of patient records of 1513 patients who received an appendectomy and were diagnosed with acute appendicitis from 2015 to 2020 at King Abdulaziz Medical City, Riyadh, Saudi Arabia...

Acute appendicitis is a highly common cause of abdominal pain that presents with nausea and vomiting, characteristic physical exam findings, and imaging evidence of appendiceal inflammation. In the absence of these signs, diagnosis can be difficult. This case report demonstrates an uncommon presentation of appendicitis that led to a delay in diagnosis and aims to discuss the ways in which similar misdiagnoses can be avoided for clinicians in the future.

Background: Exploration of the risk factors of recurrent appendiceal abscess after initial non-surgical treatment without drainage in children with appendiceal abscess. Patients and Methods: The medical records of all children diagnosed with appendiceal abscess and who were treated conservatively in the Children's Hospital of Chongqing Medical University from June 2012 to June 2020 were collected. The collected cases were divided into the recurrent group and the non-recurrent group, and all clinical indicators were compared...

AIMS: Laparoscopic appendectomy (LA) for acute appendicitis (AA) is one of the most performed procedures. The effects of peritoneal lavage (PL) and the reasons to perform it have not been cleared and all meta-analyses didn't show a statistical advantage to prevent infectious complications. This study aims to investigate surgeons' perceptions during LA, comparing intraoperative findings with histological results, and exploring how surgeons' subjectivity influences the decision-making process on PL...
