is preoperative weight loss a reliable predictor of postoperative weight loss?

Summary Background Data—With preoperative risk-adjustment now well-developed, the role of intraoperative performance in surgical outcomes may be considered.

Data were collected on 45 preoperative and intraoperative variables.

Preoperative psychological health also plays an important role.

We retrospectively analyzed the charts of 78 patients (32.5%) with confirmed locally advanced disease for further information on preoperative staging, complications and mid-term oncological follow-up.

In this population, the score is predictive of morbidity and mortality, even after controlling for preoperative patient factors.6,8,9 We hypothesized that this score would be predictive of operative complications and deaths in diverse clinical environments and across a wider range of operations, and thus be of potential use in clinical care and in quality improvement initiatives to monitor and decrease operative morbidity and mortality throughout the world.

Patients with substantial coronary sten­ osis (>50%) on the preoperative angiogram were excluded.

For example, in patients undergoing ligament repair, higher preoperative catastrophizing scores predicted more severe postoperative pain over the course of the first postsurgical week (17).

This technique has a considerable advantage over navigation based on preoperative CT data, especially for the deformable organs and when the patient is positioned differently than during CT acquisition.

Periapical radiographs were obtained using the long-cone paralleling technique with the aid of regular film holders (RVG 6000, Carestream Dental) to estimate the preoperative vertical ridge dimension.

Although approximately 50% of patients who undergo cardiac surgery will develop HIT antibodies, only 1% to 2% will develop clinical HIT (thrombocytopenia with or without thrombosis).14 In general, the platelet count falls by approximately 38% immediately after CPB (and continues to decline for the first 1-2 postoperative days before rising in a continuous fashion to a level above the preoperative Table 2—[Overview of HIT] Incidence of HIT According to Patient Population and Type of Heparin Exposure Patient Population (Minimum of 4-d Exposure) Postoperative patients Heparin, prophylactic dose3,4,14,25 Heparin, therapeutic dose26 Heparin, flushesa LMWH, prophylactic or therapeutic dose14,25 Cardiac surgery patients14,27,28,29 Medical Patients with cancer24,30.31 Heparin, prophylactic or therapeutic dose24 LMWH, prophylactic or therapeutic dose26,30 Intensive care patients32 Heparin, flushes33 Obstetrics patients21,22,34,35 Incidence of HIT, % 1-5 1-5 0.1-1 0.1-1 1-3 1 0.1-1 0.6 0.4 , 0.1 , 0.1 See Table 1 legend for expansion of abbreviations.

Improvements in body image and affective disorders tend to occur in the first 1-2 years following bariatric surgery, but then may revert to preoperative levels by 3 years, despite sustained weight loss.39 Case reports detailing forensic and medical characteristics of completed suicide following bariatric surgery further illustrate this paradox.51 It may be possible that presurgical psychological distress, whether diagnosed or not, could be exacerbated if the results of surgery were disappointing or failed to yield hoped-for improvements in quality of life.

In a preoperative evaluation of 288 subjects seeking bariatric surgery, 42% had a lifetime history of major depressive disorder.41 In a review, Wadden et al42 estimate the prevalence of depression to be 25% to 30% in bariatric surgery patients.
