Emergency laparoscopic intervention for fibrous band-induced intestinal obstruction and ischemia associated with Meckel's diverticulum: A case report.

INTRODUCTION AND IMPORTANCE: Meckel's diverticulum (MD) is a common congenital malformation of the digestive tract, often asymptomatic but occasionally leading to complications such as bowel obstruction and ischemia. Timely recognition and treatment of these complications are crucial. PRESENTATION OF CASE: We report the case of a 27-year-old male patient presenting with complete intestinal obstruction and ischemia of the ileum due to a fibrous band associated with MD. The patient presented with severe abdominal pain lasting for 10 h. Physical examination revealed a distended abdomen, antalgic position, and positive decompression. Laboratory tests showed leukocytosis and elevated lactic acid levels. Computed tomography revealed dilated small bowel loops with signs of intestinal ischemia. Emergency exploratory laparoscopy confirmed a complete ileum with ischemia and identified a fibrous band originating from the mesentery, strangulating the affected loop. The fibrous band was dissected and sectioned, confirming its association with the MD, which was resected with subsequent recovery of peristalsis and vascularization of the compromised segment. The patient had a favorable postoperative recovery without complications. DISCUSSION: MD is a rare cause of bowel obstruction, requiring a high index of suspicion for diagnosis. Despite the challenges in preoperative identification, early surgical intervention is crucial to prevent adverse outcomes. This case emphasizes the importance of promptly recognizing and managing MD-related complications to optimize patient outcomes. CONCLUSION: MD should be considered in cases of acute occlusive abdomen, despite its infrequent occurrence. Early diagnosis and timely surgical intervention are essential to minimize morbidity and mortality associated with MD-related complications.

Laparoscopic right adrenalectomy in a patient with Carney syndrome: A case report.

INTRODUCTION AND IMPORTANCE: Carney complex (CNC) is an extremely infrequent multiple endocrine neoplasia syndrome characterized by distinctive pigmented skin and mucosal lesions, cardiac and noncardiac myxomatous tumors, and multiple endocrine tumors. We herein report a case of CNC and surgical and history of laparoscopic left adrenalectomy complicated with a primary pigmented nodular adrenocortical disease (PPNAD). PRESENTATION OF CASE: We present the case of a 38-year-old woman with a previous diagnosis of CNC and history of laparoscopic left adrenalectomy who consulted for severe depression refractory to medical treatment. In the laboratory tests performed, altered ACTH, prolactin, Somatomedin C-IGF-1 and estradiol. An abdomen and pelvis C/T scan was requested, where an 8 mm lesion was found at the level of the right adrenal gland. Laparoscopic right adrenalectomy was performed. Histopathology of the surgical resection specimen revealed PPNAD. DISCUSSION: CNC is an infrequent syndrome with autosomal dominant inheritance and genetically heterogeneous. PPNAD is a consistent feature in CNC patients, however, reports of Cushing's syndrome in the literature indicate that only 25-45 % of CNC patients have PPNAD. CONCLUSION: PPNAD can be present in patients with Carney complex, with surgical adrenalectomy history. With an adequate selection of patients, laparoscopic adrenalectomy with subsequent hormone replacement therapy should be performed.

Surgical resection of a presacral solitary fibrous tumor with extension to iliac vessels using Karakousis's abdominoinguinal approach: Report of a rare case.

INTRODUCTION AND IMPORTANCE: The solitary fibrous tumor (SFT) is a rare tumor of mesenchymal origin, with a reported incidence of 2.8 cases per 100,000 tumors and with distinctive histopathological and immunohistochemical characteristics. It was initially described as a pleural lesion and subsequently, it was found in different organs and tissues. The abdominoinguinal incision described by Karakousis allows a safe and radical approach for lower quadrants abdominopelvic tumors. CASE PRESENTATION: A 47-year-old man was referred to us with a 5-months history of lower backache radiating to the left lower limb. MRI and CT revealed a retroperitoneal mass of 10 cm extending to left iliac vessels. The initial diagnosis corresponded to a sarcomatous retroperitoneal tumor. It was decided to perform an abdominal exploration using Karakousis's approach for surgical resection. The immunohistochemistry and histopathological study revealed neoplasia compatible with a SFT. It was categorized as low risk for developing metastasis and death from disease, according to the new malignancy criteria. Currently, the patient is asymptomatic and disease-free at 19 months after surgery. CLINICAL DISCUSSION: Most patients with SFTs present symptoms derived from the tumor growth and the compression on adjacent structures with clinical manifestations that are frequently insidious and precede the tumor discovery. The diagnosis is based on histopathological studies. Nonetheless, when they present an extrathoracic location, they represent a diagnostic challenge, due to their variable histological characteristics. CONCLUSION: Presacral SFT is a rare entity, with a scant incidence reported regarding this location and long-term treatment. Surgical resection is needed as the immediate treatment.

Ileocecal intussusception as the initial presentation of endometriosis: case report.

Cecal endometriosis is a rare entity that can present as nonspecific acute abdominal pain and can be complicated by ileocolic intussusception, which is extremely infrequent. We present the case of a 33-year-old woman with no relevant pathological antecedents who consulted for abdominal pain for 5 days, associated with rebound tenderness and abdominal guarding on the right lower quadrant and a palpable mass during the physical examination. Computed tomography was realized and emergency surgery performed due to suspected ileocolic intussusception. The laparoscopic examination identified an ileocolic intussusception associated with a tumor. Conversion to open surgery was needed, and an oncological right hemicolectomy with ileotransverse anastomosis was carried out. Histopathological study reported ileocolic intussusception and a focus of cecal endometriosis. Currently, the patient does not have recurrences. Ileocolic intussusception secondary to deep endometriosis requires great diagnostic presumption in women of childbearing age with acute abdomen diagnosis.

La utilización de la técnica estándar multipuerto en HDLS no se ha descripto previamente. Material y métodos: entre enero y agosto del año 2018 fueron intervenidos 4 pacientes, 3 mujeres y 1 hombre, con mediana de 64 años de edad y diagnóstico de adenocarcinoma de colon derecho. Resultados: el procedimiento se realizó exitosamente en todos los pacientes, con una mediana de tiempo operatorio de 210 minutos (r:170-240). Ningún paciente tuvo complicaciones y fueron dados de alta en una mediana de 4 días (r:3-5). Todas las piezas quirúrgicas tuvieron márgenes negativos y un recuento ganglionar > 12 ganglios. A 7, 5, 4 y 2 meses del seguimiento, los pacientes se hallan vivos y libres de enfermedad. Conclusión: la técnica de HDLS multipuerto es una alternativa sencilla, factible y segura para el tratamiento del cáncer de colon en pacientes seleccionados, con un resultado funcional, estético y oncológico favorable.

Background: The suprapubic approach for laparoscopic right hemicolectomy has been reported with robotic surgery or single incision laparoscopy. The use of the suprapubic approach for standard multiport laparoscopic right hemicolectomy has not been previously described. Material and methods: Between January and September 2018, four consecutive patients (three women and one man; median age: 64 years) with right-sided colon cancer underwent laparoscopic right hemicolectomy using the suprapubic multiport approach. Results: The procedure was successful in all the patients and mean operative time was 210 minutes (IQR: 170-240). There were no complications and were discharged on postoperative day 4 (IQR: 3-5). All the surgical specimens had negative margins and lymph node count was > 12 lymph nodes. All the patients are alive and free from disease at 7, 5, 4 and 2 months of follow-up. Conclusion: The suprapubic approach for standard multiport laparoscopic right hemicolectomy is an easy, feasible and safe alternative for the treatment of colon cancer in selected patients, with a favorable functional, esthetic and oncological result.
