Ultra-effective modified clinoptilolite adsorbent for selective thorium removal from radioactive residue.

This study investigated the efficacy of using phosphate-modified zeolite (PZ) as an adsorbent for removing thorium from aqueous solutions. The effects of various factors such as contact time, adsorbent mass, initial thorium concentration, and pH value of the solution on the removal efficiency were analyzed using the batch technique to obtain optimum adsorption condition. The results revealed that the optimal conditions for thorium adsorption were a contact time of 24 h, 0.

Post-cholecystectomy syndrome: A cohort study from a single private tertiary center.

Objectives: Although post-cholecystectomy syndrome (PCS) is a well-recognized complication, there are few reports arising from KSA. The effect of sleeve gastrectomy or endoscopic retrograde cholangiopancreatography (ERCP) stenting on the development of PCS is unknown. We aimed to measure the possible factors affecting the development of PCS, such as symptom duration, comorbidities, previous bariatric surgery, ERCP stent insertion, surgical intervention, conversion to open surgery and complication rate.

Gallbladder wall thickness adversely impacts the surgical outcome.

Backgrounds/aims: To evaluate surgical outcomes of patients with gallbladder wall thickness (GBWT) > 5 mm.

Methods: Patients who underwent cholecystectomy were classified into two groups according to their GBWT status (GBWT+ vs. GBWT-).

Modification of Clinoptilolite as a Robust Adsorbent for Highly-Efficient Removal of Thorium (IV) from Aqueous Solutions.

The natural zeolite has been modified with sulphate and phosphate. The adsorption of thorium from the aqueous solutions by using the natural and modified zeolites has been investigated via a batch method. The adsorbent samples were characterized by X-ray Diffraction (XRD), N adsorption-desorption (BET), Fourier transform infrared (FTIR), field emission scanning electron microscopy (FESEM), and energy dispersive X-ray spectroscopy (EDX).

The incidental finding of xanthogranulomatous cholecystitis: a report of 10 cases.

There is insufficient clinical knowledge about xanthogranulomatous cholecystitis (XGC) due to biased reporting. This study aims to investigate the incidence of XGC and evaluate the clinical outcome regarding operative time, rate of conversion and intraoperative or postoperative complications. We included 1141 patients who underwent surgery for gallbladder disease between January 2019 and December 2021.

Complicated appendicitis increases the hospital length of stay.

Background: There are insufficient data from Saudi Arabia regarding appendectomy outcomes and hospital length of stay. Further, there is a need to compare the length of stay of Saudi patients and the literature. The purpose is to evaluate the surgical outcomes and hospital length of stay for complicated appendicitis and simple appendicitis.

Analysis of 190 Female Patients after Appendectomy.

This study is a retrospective cohort review carried out at a single, private tertiary center. We included 190 female patients who underwent surgery for acute appendicitis between January 2016 and December 2018. Two groups of patients were analyzed based on the pregnancy.

Omental infarction present with right upper quadrant pain, case report.

Omental infarction is a rare cause of pain and must be considered in the differential diagnosis of acute abdomen. It arises in any quadrant that contains omentum when a compromised blood supply takes place. We report a morbid obese 45-year-old male with Diabetes mellitus, dyslipidemia and coronavirus-disease-related pneumonia 2 months prior to his emergency presentation with acute epigastric and right upper quadrant pain.

Case Report: Ectopic Liver (Choristoma) Discovered During Laparoscopic Cholecystectomy.

BACKGROUND Ectopic liver (EL) is liver tissue that is not attached to the mother liver, and is also known as choristoma and hepar succenturiatum. According to Watanabe's 1060-patient series, it has an incidence rate of less than 1% (0.47%).

Robot-assisted intersphincteric resection facilitates an efficient sphincter-saving in patients with low rectal cancer.

Purpose: Few investigations of robot-assisted intersphincteric resection (ISR) are presently available to support this procedure as a safe and efficient procedure. We aimed to evaluate the utility of robot-assisted ISR by comparison between ISR and abdominoperineal resection (APR) using both robot-assisted and open approaches.

Methods: The 558 patients with lower rectal cancer (LRC) who underwent curative operation was enrolled between July 2010 and June 2015 to perform either by robot-assisted (ISR vs.

Prognostic and Oncologic Significance of Perineural Invasion in Sporadic Colorectal Cancer.

Background: The presence of perineural invasion (PNI) in colorectal cancer (CRC) indicates a more aggressive phenotype, resulting in a poor prognosis. The aims of this study were to evaluate the oncologic outcome of PNI+ tumors and to investigate whether PNI status affects patient survival.

Methods: The study retrospectively enrolled 3807 patients from a single institution who underwent surgery for colorectal adenocarcinoma between January 2006 and December 2010.

Utility of indocyanine-green fluorescent imaging during robot-assisted sphincter-saving surgery on rectal cancer patients.

Background: There have been few studies describing the use of indocyanine green (ICG) fluorescent imaging during robot-assisted (RA) sphincter-saving operations (SSOs) and assessing its potential role in reducing anastomotic leak (AL).

Methods: A consecutive cohort of 436 rectal cancer patients who underwent curative RA SSOs were prospectively enrolled during 2010-2014, including 123 patients with ICG imaging (ICG group) and 313 patients without ICG imaging (ICG group).

Results: ICG imaging appeared to be helpful in identifying competent perfusion of the bowel adjacent to the anastomosis in 13 patients (10.
