Body contouring surgery following massive weight loss positively affects a patient's quality of life. However, the procedure is prone to complications. Herein, we stratified complications timewise. Furthermore, we examined whether the weight loss method -bariatric surgery or lifestyle changes -affected the frequency or severity of complications. In this single-centre retrospective analysis, we included 158 patients with massive weight loss undergoing body contouring surgery between 2009 and 2015. We recorded 96 complications in 80 patients, with an overall rate of 51%. Most complications (80.2%) were minor (Clavien-Dindo grades 1 and 2) and superficial wound infections. Immediate complications (0-24 hours postoperation) affected 8.3% of patients, with early complications (1-7 post-operative days) affecting 16.7% of them and late complications (8-30 post-operative days) affecting 58.3% of them. We found no statistical difference in complication rates when comparing bariatric and nonbariatric patients. Older age (p = 0.042) at operation is associated with an increased risk for immediate haematoma or bleeding requiring surgery. Among early complications, a high maximum weight (p = 0.035) and a high preoperative weight (p = 0.0053) significantly correlated with a haematoma or bleeding requiring surgery. For late complications, seroma correlated with older age (p = 0.0061). Complications are primarily minor and non-life threatening after body contouring surgery because of frequent massive weight loss. Here, no particular subgroup of massive weight loss patients appeared more prone to complications. Thus, for each patient, the risks associated with body contouring surgery following massive weight loss should be considered individually.

Purpose Overweight and obesity are major risk factors for perinatal morbidity and mortality, and the need for bariatric surgery (BS) among fertile-aged women is increasing. This study evaluates the outcome of post-BS pregnancies and deliveries. Methods All 20–45-year-old patients delivering between 2004 and 2016 in Finland were included. Patients with previous BS were identified from the hospital discharge register, and the medical birth register was queried for data on pregnancies, deliveries, and perinatal outcomes. The data were matched using personal identification codes, and the outcomes of women with previous BS were compared with those of other pregnancies. Results Women with previous BS (n = 314) constituted the bariatric group. When compared with the non-bariatric group (n = 750,019), they were older (p < 0.001), heavier (p < 0.001) and had more previous pregnancies (p < 0.001). The overall incidence of pregnancy-induced hypertension (p = 0.002), gestational diabetes (GDM) (p = 0.018), pre-term contractions (p = 0.023), pre-term delivery (p = 0.003), labour induction (p < 0.001), planned (p = 0.001) and unplanned (p = 0.036) caesarean sections and low birthweight infants (p < 0.001) were significantly higher in the bariatric group. When compared with body mass index–specific categories, the main outcomes were increased incidence of GDM and small for gestational age (SGA) newborns in the bariatric group. Conclusion BS can be considered a safe and advisable treatment for obesity among fertile-aged women. The pregnancy outcome is associated with post-BS weight, but the risk for GDM and small for gestational-age newborns is increased.

Massive weight loss might lead to excess skin folds causing functional, physical, and psychosocial discomfort. Following bariatric procedures, an increasing number of patients are seeking lower body contouring surgery (LBCS). The proportion of bariatric patients who undergo LBCS is largely unknown. The aim of this current study was to analyse the incidence and realization of LBCS in bariatric patients in Finland. National retrospective register linkage study including all adult patients who received bariatric surgery in Finland during 1998-2016. The data were obtained from the Finnish national health registers maintained by the Finnish Institute for Health and Welfare. Altogether 1089 (14.1%) of 7703 bariatric patients underwent LBCS during the study period. The majority of the LBCS procedures were abdominoplasty (89%). Median latency between bariatric surgery and LBCS was 31 months. The patients with LBCS were younger (p < 0.001) and received sleeve gastrectomy (p < 0.001). We revealed an annual correlation between LBCS and bariatric procedures (r ¼ 0.683). With a two-year latency between the bariatric and post-bariatric operations, the correlation co-efficiency was strong (r ¼ 0.927). LBCS operations ranged from 5 to 215 per hospital district. Most LBCSs (97.3%) were performed in public hospitals, and some (41%) were performed in university hospitals. This study shows that only 14.1% of bariatric patients undergo LBCS. There is a correlation between bariatric procedures and succeeding plastic surgical reconstructive procedures.
