Pneumoperitoneum and Pneumatosis cystoides intestinalis, a dangerous mixture. A case report.

BACKGROUND: Pneumatosis cystoides intestinalis (PCI) is a rare condition characterized by gas infiltration into the intestine wall. When gas is seen in the intestinal wall, it is usually a sign of bowel wall infarction and a surgical emergency; therefore, an adequate differentiation of benign and urgent conditions of pneumatosis intestinalis is necessary to prevent misdiagnosis and inadequate therapies. CASE PRESENTATION: We present the case of a 79-year-old male with past medical history of Alzheimer's, cholecystectomy, and umbilical hernia. PCI was identified, and conservative therapy was started. Since the patient's pain persisted, a complication was suspected, and surgery was decided. After successful treatment, the patient completely recovered. CONCLUSION: There are many benign and life-threatening causes of pneumatosis intestinalis, the imaging appearance of both may look very similar. Therefore, clinical history, physical examination, and laboratory test results are the best indicators of whether it is due to a benign or life-threatening cause. PCI must be managed with a multidisciplinary team of clinicians, radiologists, and surgeons to achieve better results for our patients.

Giant ovarian cystadenocarcinoma in an adult patient, a rare finding in modern times.

Ovarian cancer (OC) is one of the most commonly diagnosed cancers among women. Regretfully due to its a broad spectrum of clinical behavior and challenging diagnosis most cases are diagnosed at a late stage. On rare occasions, these tumors can grow to massive sizes if left untreated, worsening the prognosis of the patient. Thanks to the advancement of medicine and diagnostic techniques, these rare cases are less frequent. Timely detection and surgery could avoid all these potentially troublesome scenarios. We report the case of a 64-year-old female with a giant 13 kg high-grade papillary serous ovarian cystadenocarcinoma, the tumor grew during a four year period and was adequately treated with surgery and is under close follow up with the oncologist. To our knowledge, this is the first case of a giant ovarian cystadenocarcinoma ever reported in Ecuador.

Subcapsular liver hematoma after extracorporeal shock wave lithotripsy, a rare complication.

Extracorporeal shock wave lithotripsy (ESLW) is a common and relatively safe procedure, with a high success rate and low adverse effects. Complications of this procedure are usually limited to the kidneys and almost always resolve spontaneously. However, on rare occasions, a frightening complication, as a hematoma of a parenchymatous organ, such as the liver can appear. Abdominal pain is usually the only manifestation when a liver hematoma develops, and should always be investigated, as this dreaded complication can put the patient's life at risk. Conservative treatment is usually the treatment of choice, nevertheless, on severe cases that do not respond to conservative measures, surgery or embolization is necessary. We report the case of a 38-year-old male who underwent ESWL, 12 h after the procedure he presented to the emergency room with severe abdominal pain, after complementary exams a liver hematoma was detected. Following conservative management, the patient fully recovered.

Colonic perforation due to amebiasis, a rare and lethal complication.

Amebiasis is still a major healthcare concern, especially in developing countries like Ecuador. The lack of sanitary control and hygiene measures make parasites infections still a burden for patients and physicians. Despite infections due to this parasites are usually mild, severe infections and fatal outcomes although rare still occur. Bowel perforation is a rare complication of amebiasis, and unfortunately, it continues to be almost fatal. We present a case of an Ecuadorian patient who presented to the emergency room with an acute abdomen, despite adequate surgery and critical care, the patient regrettably died. Bowel perforation due to Entamoeba histolytica was the final diagnosis.

Massive retroperitoneal dedifferentiated liposarcoma in a young patient.

Liposarcomas are rare malignant tumors that mostly develop in the retroperitoneum. They have a broad behavioral spectrum, from small masses of tissue to highly aggressive tumors. The dedifferentiation process occurs in up to 10% and it's most likely to occur in the retroperitoneum, a process that not only changes its components but also its prognosis. These tumors can grow to a massive size since most of them do not give any symptoms until they invade the adjacent structures. Timely detection and surgery could avoid all these potentially lethal scenarios. We present a case of a 34-year-old patient, who reported a growing mass in her abdomen that reached massive proportions but remained untreated due to lack of sufficient access to healthcare facilities in her geographic location. After complete removal of the mass the patient underwent complete recovery, dedifferentiated liposarcoma was the final diagnosis.

Laparoscopic approach to non-communicating intestinal duplication cyst in adult.

Intestinal duplication is rare congenital pathology generally diagnosed in infancy or early childhood. Presentation in adults is extremely rare. We present a case of a 36-year-old otherwise healthy female patient without any past medical history. She presented with a month of lower abdominal pain, clinical examination revealed pain and a palpable mass in the lower abdomen. CT scan confirmed a cystic mass dependent of the cecum wall and colonoscopy showed an extrinsic compression of the lateral wall of the ascending colon. However, the mucosa and the rest of the colon appeared normal. Since pain became more intense laparoscopy was performed and a cystic mass dependent on the cecum was discovered. Laparoscopic hemicolectomy was performed. Patient underwent full recovery. On follow up controls, pathology described intestinal cystic duplication of the colonic wall.
