Case Competition 2023 Case 5 Giant Panniculectomy in schizophrenic patient
Authors: Sahar Vanessa Amiri, Resident, Herlev Hospital, Denmark
A 47-year-old male, with known schizophrenia, severe adiposities and hypertension and who lives in a protected home was referred to the department of plastic surgery in October 2021. The patient had lost in total 39 kgs on Saxenda and calorie reduced diet to a weight of 167 kg (BMI 54) pre-operatively, over a period of one year. He had physical difficulties mobilizing (for example turning in bed which effected his sleeping), hygiene problems, multiple skin ulcers and had previously been admitted with erysipelas. He had psycho-social disturbances affecting his daily life, he isolated himself in his home and couldn’t participate in communal activities. He had to discontinue smoking (smoked around 30 cigarettes daily) and maintain the weight loss. He was approved for surgery in November 2021, however the operation got postponed because of covid-19 and delayed proper diagnostic imaging of the patient pre-operatively. An MRI from February 2022 was inadequate, therefore a CT- abdomen was done in March 2023, that showed minimal herniation of the umbilicus but no defects on the abdominal wall or intraabdominal pathology. Planned operation in 2022 was postponed because the patient had covid-19 infection. The patient had gained weight up to 190 kilograms (BMI 62) pre-operatively. However, he was motivated to lose weight again if the giant pannus could be removed, he had still managed to maintain cessation of smoking.
