B Lymphoblastic Lymphoma

B-lymphoblastic lymphoma is a neoplasm of immature B cells and is characterized by aggressive behavior and disease progression. Common sites of involvement are skin, lymph nodes, bone, soft tissues, breast, and the mediastinum. Gastrointestinal lesions are rarely encountered and therefore not fully described. We herein report the case of a 28-year-old male, who presented with abdominal pain and CT scan showed a tumor involving the small bowel and its mesentery. He underwent emergency laparotomy and enterectomy. Histopathology report revealed B-lymphoblastic lymphoma affecting the small bowel and the adjacent mesentery. This is the first documented case of a small bowel tumor diagnosed as B-lymphoblastic lymphoma in published literature.

Gastrointestinal Lesions

<b><i>Background:</i></b> Endoscopic resection of dysplastic lesions in early stages of cancer reduces mortality rates and is recommended by many national guidelines throughout the world. Snare polypectomy and endoscopic mucosal resection (EMR) are established techniques of polyp removal. The advantages of these methods are their relatively short procedure times and acceptable complication rates. The latter include delayed bleeding in 0.9% and a perforation risk of 0.4–1.3%, depending on the size and location of the resected lesion. EMR is a recent modification of endoscopic resection. A limited number of studies suggest that larger lesions can be removed en bloc with low complication rates and short procedure times. Novel techniques such as endoscopic submucosal dissection (ESD) are used to enhance en bloc resection rates for larger, flat, or sessile lesions. Endoscopic full-thickness resection (EFTR) is employed for non-lifting lesions or those not easily amenable to resection. Procedures such as ESD or EFTR are emerging standards for lesions inaccessible to EMR techniques. <b><i>Summary:</i></b> Endoscopic treatment is now regarded as first-line therapy for benign lesions. <b><i>Key Message:</i></b> Endoscopic resection of dysplastic lesions or early stages of cancer is recommended. A plethora of different techniques can be used dependent on the lesions.

Gastrointestinal Lesions

<b><i>Introduction:</i></b> Endoscopic submucosal dissection (ESD) is a well-established endoscopic technique for the treatment of gastrointestinal lesions. Colorectal ESD outcomes are less reported in the Western literature, and Portuguese data are still very scarce. Our aim was to describe our experience on colorectal ESD regarding its outcomes and safety profile. <b><i>Methods:</i></b> We conducted a retrospective evaluation of recorded data on ESDs performed between 2015 and 2020. Only ESDs performed on epithelial neoplastic lesions were selected for further analysis. <b><i>Results:</i></b> Of a total of 167 colorectal ESDs, 153 were included. Technical success was achieved in 147 procedures (96%). The lesions were located in the colon (<i>n</i> = 24) and rectum (<i>n</i> = 123). The en bloc resection rate was 92% and 97%, the R0 resection rate was 83% and 82%, and the curative resection rate was 79% and 78% for the colon and the rectum, respectively. The need for a hybrid technique was the only risk factor for piecemeal or R1 resection. We report a perforation rate of 3.4% and a 4.1% rate of delayed bleeding; all the adverse events were manageable endoscopically, without the need of blood transfusions or surgery. Most of the lesions were laterally spreading tumours of the granular mixed type (70%), and 20% of the lesions were malignant (12% submucosal and 8% intramucosal cancer). <b><i>Conclusion:</i></b> Our series on colorectal ESD reports a very good efficacy and safety profile. This technique can be applied by endoscopists experienced in ESD.
