Aim: Natural orifice specimen extraction surgery (NOSES) has gained significant importance in treating cancers. The current study is a meta-analysis that aimed to assess the short-term efficacy and long-term prognostic impact of NOSES and conventional laparoscopic (CL) surgery in the treatment of colorectal cancer (CRC).

Method: Published reports in several medical databases up to February 2024 were searched and information pertinent to outcomes of NOSES and CL in retrospective and randomized studies to treat CRC was collected.

Background: Laparoscopic approaches and robot-assisted operations are used for colorectal cancer surgery because of their minimal invasiveness. 1 However, changes in intra-abdominal pressure during laparoscopy can lead to cardiovascular complications in compromised patients; 2 obesity and intraabdominal adhesions may further interfere with laparoscopic procedures. The retroperitoneal approach may facilitate minimally invasive surgery, even in patients with comorbidities.

Article Synopsis
  • Ferroptosis leads to significant changes in mitochondria, impacting their function and contributing to specific types of cell death tied to iron levels and oxidative stress.
  • Recent research highlights the role of iron metabolism and how mitochondrial dynamics connect to ferroptosis, especially in cancer, pointing toward new therapeutic avenues.
  • Understanding how anastasis interacts with ferroptosis and resistance to chemotherapeutics may help design better cancer treatments by targeting molecular pathways that could inhibit cell survival pathways while inducing cell death.

Article Synopsis
  • - This case study highlights a rare instance of colorectal cancer spreading to the fallopian tube and uterus in a 61-year-old woman, who initially underwent surgery for stage pT3N0M0 colorectal cancer.
  • - After a six-month follow-up without issues, she experienced a recurrence and started chemoradiotherapy, leading to a full response.
  • - Eventually, pelvic pain led to imaging that revealed a mass in her fallopian tube and uterus, resulting in surgery that confirmed the metastasis of her rectal cancer.

Background: Pelvic malignancies consistently pose significant global health challenges, adversely affecting the well-being of the male population. It is anticipated that clinicians will continue to confront these cancers in their practice. Nanomedicine offers promising strategies that revolutionize the treatment of male pelvic malignancies by providing precise delivery methods that aim to improve the efficacy of therapeutic outcomes while minimizing side effects.

Background: Colorectal cancer is among the most common cancers in the world, and splenic flexure colon cancer accounts for about 2-5% of them. There is still no consensus on the surgical treatment of splenic flexure colon cancer (SFCC), and the extent of surgical resection and lymph node dissection for SFCC is still controversial.

Aim: To compare the postoperative and long-term oncologic outcomes of extended right colectomy (ERC), segmental colectomy (SC) and left colectomy (LC) for SFCC.

In recent years, the incidence of colorectal cancer (CRC) and breast cancer (BC) has increased worldwide and caused a higher mortality rate due to the lack of selective anti-tumor therapies. Current chemotherapies and surgical interventions are significantly preferred modalities to treat CRC or BC in advanced stages but the prognosis for patients with advanced CRC and BC remains dismal. The immunotherapy technique of chimeric antigen receptor (CAR)-T cells has resulted in significant clinical outcomes when treating hematologic malignancies.

Colorectal cancer (CRC) is the second most common cause of cancer-related death among both men and women worldwide and the third most common cancer overall. About 20% of patients diagnosed with CRC were discovered to have distant metastatic lesions, the majority of which were located in the liver. For the optimum treatment of CRC patients with hepatic metastases, interventional radiologists, medical oncologists, and surgeons must all collaborate.

Objectives: Radical surgery for sigmoid colon cancer is commonly performed with complete mesocolic excision (CME) and apical lymph node dissection, reached by central vascular ligation (CVL) of the inferior mesenteric artery (IMA) and associated extended left colon resection. However, IMA branches can be ligated selectively according to tumor location with D3 lymph node dissection (LND), economic segmental colon resection and tumorspecific mesocolon excision (TSME) if IMA is skeletonized. This study aimed to compare left hemicolectomy with CME and CVL and segmental colon resection with selective vascular ligation (SVL) and D3 LND.

Article Synopsis
  • The incidence of early-onset colorectal cancer (diagnosed in individuals under 50) is on the rise globally, with distinct clinical and molecular characteristics compared to late-onset cases.
  • Factors contributing to this increase may include diet, obesity, antibiotic use, and changes in gut microbiome, with most cases occurring sporadically rather than being genetically inherited.
  • There is a need for tailored preventive and therapeutic approaches for early-onset colorectal cancer, as younger patients often present with more severe disease stages but similar outcomes to older patients after treatment.

Purpose Of Review: To investigate the possible effects of severe acute respiratory syndrome-related coronavirus 2 (SARS-CoV-2) on kidney function and assess the rate of viral ribonucleic acid (RNA) shedding/detection in urine.

Recent Findings: Most of the research on the topic suggests that for the moment our ability to estimate whether SARS-CoV-2 is a direct causative agent in acute kidney injury (AKI) or whether it has a cytokine storm effect is limited. During our prospective assessment of 333 patients with COronaVIrus Disease 2019 (COVID-19) it was found that frequency of AKI of 9.

Background: In a surgical setting, COVID-19 patients may trigger in-hospital outbreaks and have worse postoperative outcomes. Despite these risks, there have been no consistent statements on surgical guidelines regarding the perioperative screening or management of COVID-19 patients, and we do not have objective global data that describe the current conditions surrounding this issue. This study aimed to clarify the current global surgical practice including COVID-19 screening, preventive measures and in-hospital infection under the COVID-19 pandemic, and to clarify the international gaps on infection control policies among countries worldwide.

Subtotal and extended left colectomies with ileocecal junction preservation represent preferable alternatives in cases of massive involvement of the colon in the pathological process. However, these approaches might be challenging in terms of reconstructive steps. Antiperistaltic cecorectal anastomosis is one of the possible techniques.
