Item Metadata only Appendiceal wall thickness and Alvarado score are predictive of acute appendicitis in the patients with equivocal computed tomography findings(2023-12-01) Krisem M.; Jenjitranant P.; Thampongsa T.; Wongwaisayawan S.; Mahidol UniversityAround 8–13% of the patients who underwent CT scan for diagnosis of appendicitis had equivocal CT results. About one-third of these patients had acute appendicitis and this caused diagnostic challenge to the clinicians. This study was conducted... to identify clinical and imaging features that were predictive of acute appendicitis in patients who had equivocal CT findings. During January 2015 to June 2021, we retrospectively included 103 consecutive CT scans of adult patients (22 men and 81 women; meanItem Metadata only CT of appendicoliths in adult appendicitis: clinical significance and characteristics of overlooked cases(2023-01-01) Kaewlai R.; Wongveerasin P.; Lekanamongkol W.; Wongsaengchan D.; Teerasamit W.; Tongsai S.; Khamman P.; Chatkaewpaisal A.; Noppakunsomboon N.; Apisarnthanarak P.; Mahidol UniversityObjectives: Accurate computed tomography (CT) identification of appendicoliths in adults with acute appendicitis is crucial as it may preclude nonoperative management due to high risk of failure and complications. This investigation aimed... to identify the significance of appendicoliths in acute appendicitis and to evaluate the performance of portovenous-phase (PVP) CT and the consequences of overlooked appendicoliths. Methods: CT examinations of 324 consecutive patients (mean age 51.9 years, 112Publication Metadata only Predictive ability of CT findings in the differentiation of complicated and uncomplicated appendicitis: a retrospective investigation of 201 patients undergone appendectomy at initial admission(2021-12-01) Jidapa Iamwat; Wanwarang Teerasamit; Piyaporn Apisarnthanarak; Napakadol Noppakunsomboon; Rathachai Kaewlai; Siriraj HospitalBackground: Paradigm shift toward nonoperative management (NOM) of adult appendicitis has made computed tomography (CT) more important than ever, particularly in differentiating complicated from uncomplicated disease. Complete surgical... and pathological data of appendicitis in a place where appendectomy at initial admission is a standard of care would allow retrospective review of preoperative CT for performance and predictive ability in identifying those that may benefit from NOM in the futurePublication Metadata only Fungal appendicitis: a case series and review of the literature.(2013-07-04) Noppadol Larbcharoensub; Paisarn Boonsakan; Wasana Kanoksil; Duangkamol Wattanatranon; Sith Phongkitkarun; Sani Molagool; Siriorn P. Watcharananan; Mahidol UniversityAppendicitis is a condition characterized by inflammation of the vermiform appendix, which is commonly caused by bacterial infections and rarely caused by fungal organisms. In the present study, we reviewed the prevalence, clinicopathological... features, and therapeutic management of fungal appendicitis. During July 2010 to June 2011, the pathology of 262 resected vermiform appendices was reviewed. Fungal appendicitis occurred in 1.15%, including two cases of Candida spp and one caseItem Metadata only Efficacy and cost-utility of antibiotic uses and surgical treatments in uncomplicated acute appendicitis(Mahidol University. Mahidol University Library and Knowledge Center, 2024) Napaphat Poprom; Ammarin Thakkinstian; Sasivimol Rattanasiri; Chumpon Wilasrusmee; Oraluck PattanaprateepAppendicitis is the most common abdominal urgent condition in general surgical practice. Although appendectomy was a gold standard treatment management, its procedure was associated with post-operative complications and new instruments... and technologies have been launched over times. Recently, conservative treatments with antibiotics have been studied and considered as an alternative choice for uncomplicated appendicitis and individual antibiotics might have more cost-utility than appendectomyPublication Metadata only Eosinophilic appendicitis caused by schistosoma japonicum: A case report and review of the literature(2010-09-01) Wasana Kanoksil; Noppadol Larbcharoensub; Pannathat Soontrapa; Sith Phongkitkarun; Suthus Sriphojanart; Prawat Nitiyanant; Mahidol UniversityParasitic appendicitis is uncommon. The authors reviewed the pathology of 4,130 appendices resected over the past 10 years (2000 to 2009). Only one case of eosinophilic appendicitis caused by Schistosoma japonicum was identified. The overall... prevalence of schistosomal appendicitis was 0.024%. The case was a 61-year-old woman who presented with right lower quadrant abdominal pain. She had been a farmer in Chumphon and Surat Thani Provinces, which are endemic for schistosomiasis in ThailandItem Metadata only Validation of scoring systems for the prediction of complicated appendicitis in adults using clinical and computed tomographic findings(2023-12-01) Kaewlai R.; Tongsai S.; Teerasamit W.; Wongsaengchan D.; Noppakunsomboon N.; Khamman P.; Chatkaewpaisal A.; Apisarnthanarak P.; Mahidol UniversityObjectives: The study aimed to evaluate scoring systems for predicting complicated appendicitis in adults diagnosed with acute appendicitis on computed tomography. Methods: Three hundred twenty-five consecutive adult patients (mean age 51.9 ± 19....6 years, 212 women) diagnosed with acute appendicitis on computed tomography were retrospectively included. Clinical and imaging findings were compared between patients with and without complicated appendicitis, and independent associations were identifiedPublication Metadata only Diagnostic performance of CT findings in differentiation of perforated from nonperforated appendicitis(2010-12-01) Wanwarang Suthikeeree; Lassanun Lertdomrongdej; Apinya Charoensak; Mahidol UniversityObjective: To assess performance of CT finding in differentiation of perforated from non-perforated appendicitis in Siriraj hospital, Bangkok, Thailand and evaluate accuracy of each finding by using multidetector row computer tomography (MDCT...). Material and Method: Between June 2006 and May 2009, all adult patients (age more than 15 years) who had a diagnosis of acute appendicitis in Siriraj Hospital that was confirmed by pathology or surgical records and received a CT scan whole abdomen or lowerItem Metadata only Low-keV virtual monoenergetic images with rapid kilovoltage-switching DECT for differentiating complicated from uncomplicated appendicitis in adults(2025-01-01) Wongsaengchan D.; Chatpuwaphat J.; Thiravit S.; Tongsai S.; Noppakunsomboon N.; Kaewlai R.; Wongsaengchan D.; Mahidol UniversityObjectives: Low-keV virtual monoenergetic images on dual-energy CT (DECT) enhance iodine attenuation in inflamed appendiceal walls, but the role in differentiating complicated from uncomplicated appendicitis remains unclear. This is particularly... relevant given the shift toward nonoperative management of uncomplicated appendicitis. Methods: Consecutive adult patients with pathologically confirmed acute appendicitis who underwent preoperative rapid-kVP-switching DECT and appendectomy within 24 h wereItem Metadata only Low-Dose Abdominal CT for Evaluating Suspected Appendicitis in Adolescents and Young Adults: Review of Evidence(2022-05-01) Park J.H.; Salminen P.; Tannaphai P.; Lee K.H.; Mahidol UniversityDue to its excellent diagnostic performance, CT is the mainstay of diagnostic test in adults with suspected acute appendicitis in many countries. Although debatable, extensive epidemiological studies have suggested that CT radiation is carcinogenic..., at least in children and adolescents. Setting aside the debate over the carcinogenic risk of CT radiation, the value of judicious use of CT radiation cannot be overstated for the diagnosis of appendicitis, considering that appendicitis is a very common
