We report an extremely rare case of acute acalculous cholecystitis on a COVID-19 patient. In our knowledge, this is the first report of laparoscopic cholecystectomy performed on a COVID-19 patient.

Desmoids are rare mesenchimal tumors that may originate also inside the abdomen or in the abdominal wall. These tumors are biologically characterized by a tendency to local growth, and only rarely are they able to develop distant metastases. Surgical excision usually is the best treatment with a chance of a cure. In the few reports on intraabdominal or abdominal wall desmoids, open surgery always was performed. The first case of successful laparoscopic resection of a symptomatic anterior wall desmoid tumor with intraabdominal growth is reported. During the procedure, it was difficult to mobilize and grasp the mass using the common laparoscopic instruments, but with the help of the “marionette trick,” modified suture traction technique, the tumor could be removed easily using only three trocars. With four traction sutures minimizing the wall trauma, the trick made it possible to mobilize the mass in at least, seven directions, according to the principles of physical forces and vectors. This simple trick can be helpful for other common laparoscopic procedures, avoiding the insertion of sometimes ineffective instruments through more traumatic trocars.
