Acute appendicitis represents one of the common causes of admission to the emergency department. In rare cases, patients with appendicitis can suffer complications such as intestinal obstruction. These particular cases of occlusive appendicitis with a periappendicular abscess usually occur in elderly patients and can develop in an aggressive form, nonetheless with a favorable evolution. We present a case of an 80-year-old male patient, reporting symptoms similar to an occlusive digestive pathology: abdominal pain, intestinal transit disorders, and fecal vomiting. A computerized tomography scan suggested a mechanical bowel obstruction. The patient had an exploratory laparotomy indication to find the cause of the obstruction. The peritoneal cavity inspection revealed an occlusive form of acute gangrenous appendicitis with a periappendicular abscess. An appendectomy was performed. In conclusion, as surgeons, we must always take into consideration that acute appendicitis can represent a cause of intestinal obstruction, especially in elderly patients.

Primary colorectal squamous cell carcinoma (SCC) is an extremely rare subtype of colon cancer, with an incidence of less than 1% of colorectal malignancies. We report a case of a 40-year-old male patient admitted to the emergency department with symptoms of acute intestinal obstruction. Histopathological evaluation of colonoscopic biopsies revealed squamous cell carcinoma. A sigmoidectomy was performed. In order to enrich the medical literature, we add our case to the collection of colorectal squamous cell carcinoma cases by analyzing and summarizing the clinical, pathological, and therapeutic features of this rare entity.

UNASSIGNED: This is the first case of idiopathic giant pancreatic pseudocyst (IGPP) causing intestinal occlusion, intra-abdominal hypertension (IAH) and abdominal compartment syndrome (ACS) reported in the literature. Diagnosis of IGPP in emergency is a challenge because of its rarity and the absence of a history of pancreatitis or pancreatic trauma and specific clinical presentation. Abdominal contrast-enhanced computed tomography (CECT) represents the gold standard in diagnosing of pancreatic cyst (PP). Different types of treatment of PP are reported in the literature.
METHODS: A 52-year-old Caucasian female was admitted to the Emergency Department with a three-day history of abdominal pain, inability to pass gas or stool, nausea and vomiting, oliguria and a seven-day history of abdominal swelling and swollen legs. Physical examination revealed abdominal distention, abdominal pain, swelling in the legs. CECT showed a voluminous cystic pancreatic mass suspected of neoplasm. Laboratory tests reported high serum levels of BUN, creatinine and C-reactive protein and neutrophilic leukocytosis. After preoperative diagnosis of ACS, the patient was taken to the operating room for pancreatic resection. The postoperative course was uneventful. Diagnosis of IGPP was made by histopathological examination.
UNASSIGNED: IGPP is difficult to diagnose in emergency. Although different types of drainage of IGPP are described in the literature, pancreatic resection represents the treatment of choice when a cystic pancreatic neoplasm cannot be excluded.
CONCLUSIONS: IGPP is a rare disease that may cause intestinal occlusion, IAH and ACS. Pancreatic resection if necessary is safe and therapeutic with acceptable morbidity and mortality.

UNASSIGNED: Gallstone ileus (GI) represents a rare cause of mechanical intestinal occlusion, which is caused by the impaction of a gallstones at the gastrointestinal tract, being most frequently the terminal ileum; its etiology is due to the passage of a calculum through a biliary-enteric fistula. Due to its low incidence, diagnostic suspicion and adequate initial surgical treatment are essential for an adequate clinical evolution.
UNASSIGNED: A bibliographic review on the current surgical management of GI was carried out and exemplified by the presentation a clinical case.
UNASSIGNED: 78-year-old male with bowel obstruction, upon undergoing a CT scan, a gallstone at the level of distal ileum is displayed, therefore, an exploratory laparotomy (ex lap) is performed with enterotomy and extraction of the calculus. The patient bestowed adequate postoperative clinical evolution, and the presence of a cholecystoduodenal fistula is documented by an upper endoscopy.
UNASSIGNED: GI represents an uncommon pathology, however, there is discrepancy in the literature regarding the initial surgical management, especially in whether or not a biliary procedure should be associated with emergency enterolithotomy.
UNASSIGNED: GI is associated with complications secondary to diagnostic delay and its late surgical resolution, although the initial treatment is aimed at resolving the intestinal obstruction through enterotomy and gallstone extraction, there is controversy regarding the preferred time for cholecystectomy and repair of biliary-enteric fistula, being the two-stage surgery the surgical procedure of choice, especially in patients with a high risk of complications.
UNASSIGNED: El íleo biliar (IB) es una causa poco frecuente de oclusión intestinal mecánica, causado por la impactación de un cálculo biliar en el tubo digestivo, siendo la localización más frecuente el íleon terminal; se debe al paso de un cálculo a través de una fístula bilioentérica. Debido a su baja incidencia, la sospecha diagnóstica y el tratamiento quirúrgico inicial adecuado son de gran importancia para la evolución clínica.
UNASSIGNED: Realizar una revisión bibliográfica sobre el manejo quirúrgico actual del IB y ejemplificarlo mediante la presentación de un caso clínico.
UNASSIGNED: Varón de 78 años con cuadro de oclusión intestinal, con presencia de cálculo biliar en el íleon distal por tomografía. Se realiza laparotomía exploradora con enterotomía y extracción del cálculo. Cursa con adecuada evolución posquirúrgica, documentándose fístula colecistoduodenal por panendoscopia.
UNASSIGNED: El IB es una patología poco común, por lo cual existe discrepancia en cuanto al tipo de manejo quirúrgico ideal, sobre todo en si se debe o no asociar un procedimiento biliar a la enterolitotomía de urgencia.
UNASSIGNED: El IB se asocia a complicaciones secundarias al retraso diagnóstico y a una mala elección de la técnica quirúrgica inicial. Si bien el tratamiento está encaminado a resolver la obstrucción intestinal mediante enterotomía y extracción del cálculo biliar, existe controversia en cuanto al tiempo preferido para realizar la colecistectomía y la reparación de la fístula bilioentérica, siendo la cirugía en dos tiempos el procedimiento quirúrgico de elección, sobre todo en pacientes con alto riesgo de complicaciones.

BACKGROUND: Renal cell carcinoma is the most frequent malignant neoplasia of the kidney accounting for 90 % of all renal solid tumors. Metastases from renal cell carcinoma are rarely located in the small bowel and generally their clinical presentation includes bleeding and obstruction. Intussusception in adults is an extremely rare pathological condition and only 30 to 35 % of small bowel intussusceptions are derived from malignant lesions.
METHODS: We report here a clinical case of a 75-year-old white man hospitalized for anemia and subocclusion. An abdominal ultrasound and computed tomography showed a small bowel intussusception. During a surgical exploration, a polypoid lesion was found to be the lead point of the intussusception. His small intestine was resected and a functional side-to-side anastomosis was performed. The histological features of the surgical specimen confirmed the diagnosis of metastatic renal cell carcinoma.
CONCLUSIONS: Small bowel intussusception from renal cell carcinoma metastasis should always be considered in the setting of unexplained intestinal subocclusion in patients with a history of renal cell carcinoma.
