Insights into Colorectal Cancer Screening Awareness: A Study in the Community of Taif City.

Colorectal cancer (CRC) is highly prevalent among Saudi males and females. Understanding its symptoms, risk factors, and screening is vital. This study aims to gauge CRC awareness in Taif City, Saudi Arabia, based on demographics.

Sigmoid Volvulus as a Clinical Manifestation of Acquired Colonic Hypoganglionosis: A Case Report.

A reduced and limited number of myenteric ganglia and low acetylcholinesterase activity in the lamina propria characterizes an unusual form of intestinal innervation disorder known as acquired or adult-onset hypoganglionosis. Only a few cases have been observed in adults, while the majority are diagnosed in infancy or youth. We report a rare case of colonic hypoganglionosis that presented as sigmoid volvulus in a 25-year-old female brought in to the ER.

The Effect of High Altitude on Short-Term Outcomes of Post-hemorrhoidectomy.

Background Hemorrhoids are caused by the distal displacement of the hemorrhoidal cushions and venous distention. Hemorrhoidal illness is still a prevalent issue. Hemorrhoidal symptoms affect 5% of the general population and 50% of people over the age of 50.

Relationship Between ABO Blood Group and the Risk of Colorectal Cancer: A Retrospective Multicenter Study.

Background: Colorectal cancer (CRC) is the fourth deadliest cancer, with approximately 900,000 deaths annually. CRC is a multifactorial disease in which a set of factors, including environmental, hereditary, and genetic factors, are integrated into cancer development. Studies have suggested an association between hereditary antigens in the human blood group system and the risk of different cancers.

Wound Irrigation Using Wet Gauze May Reduce Surgical Site Infection Following Laparoscopic Appendectomy.

Purpose: This study aimed to compare the perioperative outcomes of wet gauze and conventional irrigation after laparoscopic appendectomy to determine whether wet gauze irrigation can help reduce surgical site infection (SSI).

Methods: A total of 308 patients undergoing laparoscopic appendectomy were included in this study between December 2018 and May 2020. Of these, 132 (42.

Clinical effect of rectus sheath block compared to intrathecal morphine injection for minimally invasive colorectal cancer surgery: a propensity score-matched study.

Purpose: To evaluate the postoperative outcomes of a multimodal perioperative pain management protocol with rectus sheath blocks (RSBs) or intrathecal morphine (ITM) injection for minimally invasive colorectal cancer surgery.

Methods: A total of 112 patients underwent minimally invasive colorectal surgery. Forty-one patients underwent RSB (group 1), whereas 71 patients underwent ITM (group 2) in addition to multimodal pain management using enhanced recovery after the surgery protocol.

Short- and long-term outcomes of local excision with adjuvant radiotherapy in high-risk T1 rectal cancer patients.

Purpose: The standard of care for early rectal cancer is radical surgery; however, it carries high postoperative morbidity. This study aimed to assess the short-term and oncological outcomes of local excision and adjuvant radiotherapy in patients with high-risk pathological stage (p) T1 rectal cancer.

Methods: Fifty-five patients underwent local excision with adjuvant radiotherapy or radical resection for high-risk T1 rectal cancer.

Comparison of Vascular Invasion With Lymph Node Metastasis as a Prognostic Factor in Stage I-III Colon Cancer: An Observational Cohort Study.

This study aimed to evaluate the prognostic impact of vascular invasion (VI) in comparison with that of lymph node metastasis (LNM) in non-metastatic colon cancer. Patients who underwent curative surgery for stage I-III colon cancer were divided into four groups depending on the status of VI and LNM (Group I: VI-/LNM-; Group II: VI+/LNM-; Group III: VI-/LNM+; Group IV: VI+/LNM+). Group III was subdivided according to the nodal (N) stage (Group IIIA: VI-/N1; Group IIIB: VI-/N2).

Use of ascitic CEA levels as a predictive value for distant metastasis in high-risk stage II and III colorectal cancer.

Purpose: This study aimed to analyze the effect of ascitic carcinoembryonic antigen (CEA) levels on the long-term oncologic outcomes of colorectal cancer (CRC) following curative treatment.

Methods: A total of 191 patients with stage II/III CRC were included. CEA was analyzed on the peritoneal fluid samples taken at the start of each surgery.

High incidence of late anastomosis leakage in patients for rectal cancer after neoadjuvant chemoradiotherapy: A comparative study.

Purpose: The purpose of this study was to investigate the clinical features and risk factors of late anastomotic leakage (AL) in a homogeneous cohort with elective sphincter-sparing surgery (SSS) with ileostomy after neoadjuvant chemoradiotherapy (nCRT) for rectal cancer.

Methods: Data from a total of 359 patients who underwent elective rectal cancer surgery between Jan 2017 and May 2020 were retrospectively reviewed. Patients were classified into early and late AL groups, referring to onset of AL occurring within or after 30 post-operative days, respectively.

The additional analgesic effects of transverse abdominis plane block in patients receiving low-dose intrathecal morphine for minimally invasive colorectal surgery: a randomized, single-blinded study.

Purpose: Intrathecal analgesia (ITA) and transverse abdominis plane block (TAPB) are effective pain control methods in abdominal surgery. However, there is still no gold standard for postoperative pain control in minimally invasive colorectal surgery. This study aimed to investigate whether the analgesic effect could be increased when TAPB, which can further reduce wound somatic pain, was administered in low-dose morphine ITA patients.

Serial measurements of body composition using bioelectrical impedance and clinical usefulness of phase angle in colorectal cancer.

Background: Although body composition (BC) can be measured easily using bioelectrical impedance analysis (BIA), there are few studies of serial BC measurements in colorectal cancer (CRC). The purpose of the present study was to observe the serial change of BC in patients with CRC surgery from the initiation to the end of chemotherapy and to evaluate its clinical usefulness.

Methods: From July 2018 to November 2019, patients undergoing elective CRC surgery were enrolled.

Quantitative evaluation of colon perfusion after high versus low ligation in rectal surgery by indocyanine green: a pilot study.

Background: In the field of rectal cancer surgery, there remains ongoing debate on the merits of high ligation (HL) and low ligation (LL) of the inferior mesenteric artery (IMA) in terms of perfusion and anastomosis leakage. Recently, infrared fluorescence of indocyanine green (ICG) imaging has been used to evaluate perfusion status during colorectal surgery.

Objective: The purpose of this study is to compare the changes in perfusion status between HL and LL through quantitative evaluation of ICG.

Natural anticoagulants can be useful predictors of severity in chronic liver disease.

Protein S (PS), protein C (PC), and antithrombin (AT) are produced by the liver, and their levels were previously shown to be reduced in chronic as well as acute liver disease. The aim of this study was to determine whether measurement of PS, PC, and AT levels in patients would be as good as the commonly used clinical and histological parameters of liver disease in discriminating early and advanced hepatocyte dysfunction. A total of 154 patients were recruited and categorized into five groups: hepatitis B inactive carriers in group 1 (n = 29), nonalcoholic steatohepatitis patients in group 2 (n = 30), chronic hepatitis B patients with elevated liver enzymes in group 3 (n = 29), chronic hepatitis C patients with elevated liver enzymes in group 4 (n = 30), liver cirrhosis patients in group 5 (n = 36).
