Surgery for patients with endometrioid-type endometrial cancer: is lymphadenectomy above the inferior mesenteric artery necessary?

Objective: The primary objective of this study was to identify the risk of metastasis to lymph nodes above the inferior mesenteric artery (IMA) in endometrioid-type endometrial cancer (EC) and the factors that influence metastasis.

Methods: The study included patients who had been operated on for endometrioid-type EC in three gynecological oncology centers between 2007 and 2023. The supramesenteric lymph node (SM-LN) is the region between the left renal vein and the IMA, whereas the inframesenteric lymph node (IM-LN) is the region between the IMA and the aortic bifurcation, as determined by the level of the IMA.

Metastatic SMARCA4-deficient undifferentiated tumor in the small mesentery: case report.

Background: SMARCA4-deficient undifferentiated tumor (SMARCA4-UT) is a rare and highly malignant primary tumor characterized by the loss of SMARCA4 expression. Despite advancements in oncology, diagnosing and treating SMARCA4-UT remain significant clinical challenges.

Case Demonstration: A 67-year-old male with a history of smoking presented to the hospital with complaints of abdominal distention and pain lasting for more than four days.

Case Report: Acute intussusception in a 2-year-old male patient: a rare case of Burkitt's lymphoma coexisting with Meckel's diverticulum.

In children, 90% cases of intussusception are idiopathic and the remaining 10% are attributed to underlying diseases (most commonly due to Meckel's diverticulum, polyps then either duplication cyst or mesentery cysts, and rarely due to Burkitt's lymphoma). The occurrence of acute intestinal intussusception caused by Burkitt's lymphoma in children under the age of 5 is exceedingly rare. Burkitt's lymphoma presents with diverse clinical manifestations, often leading to the identification of an abdominal tumor in pediatric patients.

A Novel In Vivo Rat Mesentery Model for Studying Tumor Spheroid-Induced Microvascular Remodeling.

Introduction: The tumor microenvironment is comprised of neoplastic cells and a variety of host cell types. Investigation of cell dynamics within this environment has motivated in vitro and ex vivo biomimetic model development. Our lab recently introduced the tumor spheroid-rat mesentery model to investigate cancer-induced lymphatic/blood vessel remodeling.

A rare case of sclerosing angiomatoid nodular transformation of spleen: A case report.

Introduction And Importance: Sclerosing angiomatoid nodular transformation of the spleen is a rare benign vascular lesion arising from red pulp of spleen with unknown etiopathogenesis. It is a non-neoplastic condition that affects the spleen only; not described in other sites except one case reported in adrenal gland. Epidemiologically it has slight female predilection.

A Case of Parasitic Leiomyoma in the Sigmoid Mesentery Following Total Laparoscopic Hysterectomy.

Parasitic leiomyoma (PL) develops when fragments of a morcellated uterine leiomyoma, during procedures such as laparoscopic myomectomy (LM) or total laparoscopic hysterectomy (TLH), adhere to other tissues. We recently encountered a case where PL developed in the mesentery of the sigmoid colon following TLH. A 51-year-old woman had previously undergone TLH with in-abdominal morcellation.

Type 1a Duodenojejunal Tubular Duplication Cyst with Complex Rotational Anomaly Masquerading as Chronic Anemia.

Enteric duplication cysts and reversed intestinal rotation (RIR) are rare congenital anomalies, with their coexistence being exceptionally uncommon. We report a 4-year-old girl who presented with chronic anemia and intermittent abdominal symptoms since infancy. Detailed workup for medical causes of anemia was inconclusive.

Streamline Flow of the Portal Vein Affects the Distribution of Colorectal Cancer Metastases: Clinical Reality or Just a Belief? A Systematic Review and Meta-Analysis.

The "streamline flow" of the portal vein (PV) is a controversial yet well-known theory presented almost 125 years ago. It states that blood from the superior mesenteric vein (SMV) goes preferentially to the right liver lobe, while splenic and inferior mesenteric veins divert blood predominantly to the left lobe, affecting this way the metastatic distribution of colorectal cancer (CRC). The aim of this systematic review is to assess its validity by examining and combining all the relevant literature with a critical eye.

Temozolomide and capecitabine regimen as first-line treatment in advanced gastroenteropancreatic neuroendocrine tumors at a Latin American reference center.

Background: Numerous studies have indicated that the temozolomide and capecitabine regimen (TEMCAP) exhibits a certain level of efficacy in treating advanced, well-differentiated gastroenteropancreatic neuroendocrine tumors (GEP-NET). However, published data from Peru are limited. We hypothesize that this regimen could be a viable therapeutic option for advanced GEP-NET in the Peruvian population.

Signet-ring cell carcinoma of the transverse colon in a 10-year-old girl: A case report.

Background: Signet-ring cell carcinoma (SRCC) is a rare subtype of colorectal cancer. The incidence of primary colonic SRCC is relatively rare in pediatric patients, with a limited number of reported cases currently available. The prognosis for this specific tumor type is unfavorable, and the preoperative diagnosis presents challenges, potentially leading to misdiagnosis.

Disseminated Abdominal Cystic Echinococcosis After Blunt Abdominal Trauma: A Case Report.

Rupture of a hydatid cyst can lead to the development of a disseminated form of intra-abdominal cystic echinococcosis if not diagnosed and treated promptly. Anaphylactic shock is a definite indication of cyst rupture. The presented clinical case was a young athlete with a disseminated form of cystic echinococcosis, which was investigated in 2023 at the Syzganov National Scientific Center for Surgery of Kazakhstan.

A rare case of numerous parasitic myomas after laparoscopic myomectomy.

Parasitic myoma is a relatively rare disease in which one or more leiomyomas form outside the uterus; however, the detailed causes are unknown. Few sporadic reports are available, and per our research, the maximum number of parasitic myomas reported to date was 26, and almost all cases were treated by surgical resection. We report a rare case of numerous parasitic myomas in the abdominal cavity, possibly including an intrathoracic lesion, which could not be resected completely.

Laparoscopic excision of a spontaneously infected mesenteric duplication cyst.

Mesenteric cysts are rare intra-abdominal masses which can occur at any point in the gastrointestinal tract from the duodenum to the rectum. These cysts may remain asymptomatic or may present with an abdominal mass, abdominal pain, or fever. Management may be conservative, percutaneous, or surgical excision.

Up-regulated fatty acid-binding protein 4 promoted cardiac injury during open colorectal surgery in elderly patients.

Background: Fatty acid binding protein 4 (FABP4) has been shown to increase cardiovascular disease. The FABP4 levels in serum and adipose tissue and the possible regulatory mechanisms during colorectal cancer surgery in elderly patients remain unknown.

Methods: Four hundred elderly patients with colorectal cancer were recruited, 200 underwent laparoscopic surgery (LS) and 200 underwent open surgery (OS).

First report of acute, visceral, fatal toxoplasmosis in a naturally infected calf (Bos taurus).

Cattle are considered resistant to clinical toxoplasmosis and viable Toxoplasma gondii is rarely isolated from bovine tissues. Currently, there is no histologically confirmed case of clinical toxoplasmosis in cattle. Here, the first confirmed case of acute toxoplasmosis in cattle is reported.

Stapled Arterial Divestment in Surgery for Locally Advanced Pancreatic Cancer.

Background: Pancreatic adenocarcinoma has a predisposition to invade the neural tissue surrounding the superior mesenteric artery (SMA). Before the advent of neoadjuvant chemotherapy (NAC), any invasion of this tissue was often considered as unresectable disease. Currently, patients who respond favourably to NAC have potentially resectable disease.

Effects of mesenteric artery ligation level on patients with locally advanced rectal cancer after neoadjuvant chemoradiotherapy: a retrospective cohort study.

Background: There is currently limited research on the optimal level of inferior mesenteric artery (IMA) ligation during surgery for patients with locally advanced rectal cancer (LARC) undergoing neoadjuvant chemoradiotherapy (nCRT). We carried out a retrospective cohort study to analyze the impact of IMA ligation level on surgical outcomes and long-term patient prognosis.

Methods: The data originated from a multicenter randomized controlled trial conducted across six tertiary referral hospitals in Beijing, involving patients with LARC undergoing nCRT followed by radical surgery.

Unraveling a Rare Case of Pediatric Solid Pseudopapillary Neoplasm With a Replaced Common Hepatic Artery Arising From the Superior Mesenteric Artery.

Pancreatic solid pseudopapillary epithelial neoplasm (SPEN) is a rare pancreatic tumor with low-grade malignant potential. They often present in young women in their second and third decade of life, with only a small minority concerning children. It has a good prognosis, with a five-year survival rate of up to 97%.

Mesenteric desmoid tumor in its cystic form: Case report of a very rare variant.

Desmoid tumors, also known as deep fibromatosis or desmoid-type fibromatosis, represent a rare subset of deep fibromatoses. It is a locally aggressive tumor, with no specific symptoms, and no metastatic potential. We report a case of a 38-year-old male patient with an abdominal mass.

Protein-losing enteropathy as the first presentation of systemic lupus erythematosus the first case reported in Palestine with systemic review.

Introduction: Systemic lupus erythematosus is a chronic inflammatory disease affecting women, causing gastrointestinal issues like acute pancreatitis, esophagitis, and protein-losing enteropathy. Protein loss is uncommon, but a case study shows protein-losing enteropathy as a first sign.

Importance: Protein-losing enteropathy (PLE) is a rare gastrointestinal manifestation of SLE, often seen years before diagnosis.

Predictive model of the surgical difficulty of robot-assisted total mesorectal excision for rectal cancer: a multicenter, retrospective study.

Rectal cancer robotic surgery is becoming more and more common, but evidence for predicting surgical difficulty is scarce. Our goal was to look at the elements that influence the complexity of robot-assisted total mesorectal excision (R-TME) in the medical care of middle and low rectal cancer as well as to establish and validate a predictive model on the basis of these factors. Within this multicenter retrospective investigation, 166 consecutive patients receiving R-TME between January 2021 and December 2022 with middle and low rectal cancer were included and categorized according to the median operation time.
