Introduction And Importance: Primary inflammatory myofibroblastic tumor is a rare subgroup of mesenchymal tumors. Gastric localization is extremely rare, and patients may present with abdominal pain and a palpable abdominal mass. Here, we present a case of gastric inflammatory myofibroblastic tumor revealed by abdominal pain, which was treated with wide local excision.

Introduction And Importance: Mantle cell lymphoma is a rare type of non-Hodgkin's lymphoma which accounts for 5 % of all cases. Patients present with an advanced form of the disease. We present here a case of ileocolic intussusception secondary to mantle cell lymphoma which was revealed by abdominal pain and vomiting that was treated by surgical resection followed by chemotherapy.

Unlabelled: Gastrointestinal metastasis of pleomorphic lung cancer presents with nonspecific manifestations, leading to delayed diagnosis. Herein, the authors report the case of a 56-year-old patient who presented with gastrointestinal bleeding due to pleomorphic lung carcinoma.

Case Presentation: A 56-year-old patient presented to the emergency department with melena.

Introduction And Importance: Gallstone ileus (GI) is defined as the occlusion of the intestinal lumen due to the impaction of one or more gallstones. The optimal management of GI is not consensual. We report a rare case of GI with a successful surgical treatment for a 65 year-old-female.

The present letter to the editor is related to the work entitled "Large leiomyoma of lower esophagus diagnosed by endoscopic ultrasonography-fine needle aspiration: A case report." Although endoscopic ultrasonography seems necessary in a suspected leiomyoma of the esophagus, the performance of biopsies fine needle aspiration is controversial as it increases the risk of complications such as bleeding, infection, and intraoperative perforations. Laparoscopy is the best treatment strategy for small tumors.

Introduction And Importance: A pancreatic pseudocyst is a known complication of acute and chronic pancreatitis. A pseudocyst rupture into the abdomen causes peritonitis, which can be fatal if surgical treatment is delayed. Here in we report the case of a 46-year-old woman presenting with a pancreatic pseudocyst doubly complicated with infection and rupture causing sepsis shock.

Unlabelled: Anaplastic thyroid carcinoma (ATC) is a rare malignancy with a poor prognosis. It is characterized by abrupt development with local and distant metastases. Metastases are essentially present in the lung.

Collision tumor of the appendix is an extremely rare entity, defined as the coexistence of two independent tumors located in the same site without transitional changes. We describe in this report the case of a 75-year-old man who presented with an acute abdominal pain, nausea and vomiting. Physical examination revealed an abdominal distension with a hypogastric mass.

Introduction: Myxofibrosarcoma (MFS) is a subtype of soft tissue sarcoma characterized by diffuse infiltration patterns. Myxofibrosarcoma arises often in extremities. Its occurrence in the abdominal wall is extremely rare.

Introduction: The aim of this study was to compare the accuracy of 5-mFI (modified frailty index) to ASA score (American Society of Anesthesiologists score) in predicting postoperative mortality in patients with rectal cancer.

Materials And Methods: The ability of each parameter to predict postoperative mortality was attested in 2 ways: Area under the curve (AUC) was determined using ROC curves analysis. A comparison of AUC was performed using Delong test and Henley-McNeil test.

Introduction: Gastrointestinal stromal tumors (GIST) represent the most common mesenchymal tumors of the gastrointestinal tract. In rare cases, these tumors do not develop in the gastrointestinal tract and are defined as extra-gastro-intestinal stromal tumors (EGISTs). Pancreatic EGIST is extremely rare.

Background: Small bowel volvulus (SBV) is an aberrant rotation of the small bowel segment along the axis of its mesentery.Secondary SBV is the most frequent situation. Postoperative adhesions represent the main cause.

Several syndromic forms of digestive cancers are known to predispose to early-onset gastric tumors such as Hereditary Diffuse Gastric Cancer (HDGC) and Lynch Syndrome (LS). LSII is an extracolonic cancer syndrome characterized by a tumor spectrum including gastric cancer (GC). In the current work, our main aim was to identify the mutational spectrum underlying the genetic predisposition to diffuse gastric tumors occurring in a Tunisian family suspected of both HDGC and LS II syndromes.

Introduction: Malignant tumors of the small bowel are rare. The jejunum, ileum, and duodenum represent the most common sites of intestinal leiomyosarcoma (LMS). Herein, we present a case of a 65-year-old patient having ileal LMS successfully treated with surgical resection.

Introduction And Importance: Malignant lymphoma occurs in all the systemic organs. Rarely, large B-cell lymphoma is located in the spleen, making the diagnosis difficult. Herein, we report a patient presenting with massive splenomegaly due to LBCL.

Purpose: Intestinal ischemia (II) is the most critical factor to determine in patients with incarcerated groin hernia (IGH) because II could be reversible, and it is considered as a "time sensitive condition." Although predictive factors of II were identified in several previous studies, preoperative diagnosis of II cannot be reliably made or excluded by any known parameter. The aims of this study were: to devise and to validate a clinic-biologic score, with a strong discriminatory power, for predicting the risk of II in patients with IGH.

To our knowledge, this is one of the rare literature reports of an ileal GIST complicated with mesenteric gangrene. We reported successful surgical treatment. Infection of GIST is an extremely rare complication that should be treated with no delays to avoid rupture and peritonitis.

Introduction: Benign tumors represent less than 1% of esophageal neoplasms. Esophageal leiomyoma is a very rare tumor that arises from mesenchymal tissue. We present here a case of leiomyoma of the esophagus which was revealed by dysphagia and vomiting that was treated by surgical enucleation.

Background: Gastric and colorectal cancers are the most common malignant tumours, leading to a significant number of cancer-related deaths worldwide. Recently, increasing evidence has demonstrated that cancer cells exhibit a differential expression of potassium channels and this can contribute to cancer progression. However, their expression and localisation at the somatic level remains uncertain.

Background: Gangrenous cholecystitis (GC) is a particularly severe form of acute cholecystitis (AC) and is associated with an increased risk of postoperative morbidity and mortality. Recent reports show that surgeons are remarkably unsuccessful in diagnosing GC.

Methods: We conducted a retrospective study involving 587 patients with AC.

Background/aims: Intestinal ischaemia (II) is the most critical factor to determine in patients with adhesive small bowel obstruction (ASBO) because intestinal ischaemia could be reversible. The aim of this study was to create a clinicoradiological score to predict II in patients with ASBO.

Methods: We conducted a retrospective study including 124 patients with ASBO.
