Background: A Hartmann operation, which is the intervention by which the lower part of the sigmoid and the upper part of the rectum are resected with the closing of the rectal stump and end colostomy, has as its indications: advanced or complicated r...

Background/Objectives: Hartmann’s procedure is commonly employed to manage complications of acute sigmoid diverticulitis, such as perforation or abscess formation. However, determining the optimal timing for colostomy reversal remains a topic o...

Introduction: The objective of this study was to analyze and compare the outcomes of two surgical techniques in the emergency management of obstructed colorectal carcinoma. Methods: This is a retrospective analysis of patients’ data from a tert...

The restoration of bowel continuity following Hartmann’s Procedure (HP) has been reported hitherto with high morbidity and mortality rates. No clear guidelines exist about timing in Hartmann’s Reversal (HR), the literature data being conf...

Background and Objectives: Complicated left-sided colonic diverticulitis is one of the important causes of hospital admissions and emergency surgery in industrialized societies and requires serious clinical decision-making processes for patient manag...

Background: Several studies have suggested that laparoscopic peritoneal lavage for the treatment of diverticulitis might be associated with an increased event rate. The WSES (World Society of Emergency Surgery) guidelines recommend performing laparos...

Background and objectives: We present initial results from a small cohort series for a hospital protocol related to the emergency hospitalization decision-making process for acute diverticulitis. We performed a retrospective analysis of 53 patients w...

Objectives. The objectives of this study are to highlight the diagnostic and therapeutic difficulties in patients with complicated acute colonic diverticulosis. Methods. The study group comprised 40 patients hospitalized to the Second Surgical Clinic...

Background: The surgical management of remnant rectosigmoid after subtotal colectomy with end ileostomy for acute severe ulcerative colitis remains controversial with respect to the need to perform sigmoidostomy or Hartmann’s pouch. The aim of this r...

Purpose: Low back pain presents a serious challenge for numerous medical specialties. The purpose of this study was to assess disability due to low back pain in patients operated on due to colorectal cancer depending on the type of surgery performed....

Background: Acute diverticulitis (AD), an inflammatory complication of diverticulosis, affects around 4% of individuals with diverticulosis, with increased incidence in older populations. This study aims to assess the impact of sarcopenia, the age-re...

Background and Objectives: During the COVID-19 pandemic, many countries implemented lockdowns and social distancing measures, which may delay the early diagnosis of colorectal cancer (CRC). This study aims to review the impact of the pandemic on the...

The study was aimed at assessing the quality of sexual functioning in female patients having undergone surgical treatment for cancer depending on the type of surgery. The prospective cohort consisted of 48 female patients (23 patients with stoma [A2]...

This study constitutes a prospective, three-stage evaluation of quality of life among patients receiving surgical treatment for colorectal cancer depending on the type of surgery performed (open anterior resection, laparoscopic anterior resection, ab...

Background: The guidelines proposed by the World Society for Emergency Surgery (WSES) in 2020 for the management of Acute Diverticulitis (AD) emphasize the safety of non-operative management (NOM) in selected patients and recommend sigmoid resection...

Adaptive optics (AO) is employed for the continuous measurement and correction of ocular aberrations. Human eye refractive errors (lower-order aberrations such as myopia and astigmatism) are corrected with contact lenses and excimer laser surgery. Un...

The objective of this study was to analyze data on laparoscopic surgery for malignant diseases of the colon, rectum, and anus in Lithuania during the period of January 1, 2005, to February 15, 2008.

Material and methods. During the above-mentioned pe...

Background/Objectives: Ocular wavefront aberrations are clinically relevant for optimizing vision correction and predicting surgical outcomes. This study aimed to establish normative reference ranges for a Korean population by quantifying wavefront a...

Linear stability analysis of liquid metal flow driven by a constant pressure gradient in an insulating rectangular duct under an external uniform magnetic field was carried out. In the present analysis, since the Joule heating and induced magnetic fi...

In the existent study, combined magneto-convection heat exchange in a driven enclosure having vertical fin was analyzed numerically. The finite element system-based GWR procedure was utilized to determine the flow model’s governing equations. A param...

This research is engaged to explore biological peristaltic transport under the action of an externally applied magnetic field passing through an asymmetric channel which is saturated with porous media. The set of governing partial differential equati...

The wavefront aberrations (WAs) of a laser beam produced by an optical parametric oscillator (OPO) have been measured using a Hartmann–Shack sensor. The OPO tuning operation requires changes in the device that might affect the shape of the wave...

Virtual Shack–Hartmann wavefront sensing (vSHWS) can flexibly adjust parameters to meet different requirements without changing the system, and it is a promising means for aberration measurement. However, how to optimize its parameters to achieve the...

Atmospheric turbulence introduces distortions to the wavefront of propagating optical radiation. It causes image resolution degradation in astronomical telescopes and significantly reduces the power density of radiation on the target in focusing appl...

The laminar movement in an expanding and contracting permeable pipe or surface has recently attracted the attention of many scholars owing to its application in engineering and biological processes. The objective of the current study is to examine th...

(1) Introduction: Negative pressure wound therapy (NPWT) is a frequently applied open abdomen (OA) treatment. There are only a few experimental data supporting this method and describing the optimal settings and pressure distribution in the abdominal...

The present research examines the unsteady sensitivity analysis and entropy generation of blood-based silver–titanium dioxide flow in a tilted cylindrical W-shape symmetric stenosis artery. The study considers various factors such as the electr...

Background: The current use of endoscopic stenting as a bridge to surgery is not always accepted in standard clinical practice to treat neoplastic colonic obstructions. Objectives: The role of colonic self-expandable metal stent (SEMS) positioning as...
