Para-anal lipoma as a rare consequence to perineal trauma. Case-report and review of the literature.

Introduction: Lipomas are the most common benign mesenchymal tumors which can be found in any part of the body. Nevertheless, their etiology and pathogenesis remain unknown. It is hypothesized that some of these lesions could result from an acute or chronic trauma. Patients and methods: We report a case of a 54-year-old man presenting a perineal lipoma which volume grew rapidly after he fell on his buttock, in the context of inaugural epileptic seizure. Pelvic MRI showed a voluminous fatty mass, measuring 6.6 × 5 × 9 cm without any signs of local invasion. Furthermore, we review the latest research on lipomas originating from traumatic lesion. Results: The mass was completely excised in one block under general anesthaesia, using an elliptical incision and a deep dissection. We did not close the skin incision in view of the cutaneous defect. Post-operative recovery was uneventful and the patient was discharged from hospital two days after the operation. Histopathology indicated a reorganised lipoma with no evidence of malignancy. Conclusion: Perineal lipomas are extremely rare, pathological examination of imaging guided biopsies are needed to exclude malignancy especially a well-differentiated liposarcoma. MRI remains the first option and radical surgical excision is the gold standard treatment.

Reconstruction of an abdominal wall defect with biologic mesh after resection of a desmoid tumor in a patient with a Gardner's syndrome.

INTRODUCTION: Desmoid tumors are rare proliferative and invasive benign lesions. They can be sporadic, but in most instances, desmoid tumors develop in the context of Gardner's syndrome with principal localization in the abdominal cavity and abdominal wall. CASE-REPORT: We report the case of a 24-year-old female presenting Gardner's syndrome with a symptomatic abdominal wall desmoid tumor. Lack of response to medical treatment led to surgical management consisting in a complete resection and parietal reconstruction with a biologic mesh. Postoperative course was uneventful and there was no evidence of recurrence at 12 months of follow-up. DISCUSSION: Conventional treatment of abdominal wall desmoid tumors consists in a wide and radical resection. However, complete resection is not always feasible because of difficulty to differentiate the desmoid tumor from adjacent tissues. The surgical approach may require different techniques to repair the parietal defect including prosthetic material such as synthetic or biologic meshes. Biological mesh is an ideal alternative to synthetic graft, mainly in case of infection. CONCLUSION: We have encountered a case of a symptomatic growing desmoid tumor of the abdominal wall in a young patient with Gardner's syndrome, successfully treated by complete resection and reconstruction with a biologic mesh to correct the parietal defect.

Digital postoperative follow-up after colorectal resection: a multi-center preliminary qualitative study on a patient reporting and monitoring application.

The development of minimally invasive colorectal surgery in the last decades led to a decrease in length of hospital stay. However, readmission and postoperative complications were still observed. Several studies have shown that close postoperative follow-up is required to decrease postoperative morbidity through patient education and by detecting early signs of complications. To help in this task, multiple monitoring programs have been set up to follow patients at home, allowing detection of several complications at an early stage. To evaluate acceptance, satisfaction, usability, compliance and safety of a mobile application following postoperative colorectal patients during the first 15 days post-discharge from hospital. A mobile application enabling the communication between the patient and medical staff during the recovery phase was developed and tested in four hospitals. Patients who underwent a colorectal resection were included in this prospective qualitative study. Questionnaires to assess satisfaction and usability were handed out to patients at the end of the test period. Overall, 118 patients (52% females, median age 52.5 years) were included. Median adherence-rate during 15 days was 89.6%. Satisfaction-rate for the application was 76% and usability was high. Overall, 1220 notifications were collected, of which 722 were orange, 466 red and 32 purple, colours used to rate the severeness of complaints. We analyzed the most common notifications, showing trends in different subgroups of the study with higher risks of complications (pain (409 notifications), abnormal stools (196 notifications), and wound problems (118 notifications)). A mobile application could be used to follow patients at home after colorectal resection. Future studies should evaluate whether these applications can detect complications and prevent readmission.
