Weight loss and clinical outcomes following primary versus secondary Roux-en-Y gastric bypass: a multi-institutional experience.

BACKGROUND: Revisional bariatric surgeries are increasing for weight recurrence and return of co-morbidities. Herein, we compare weight loss and clinical outcomes following primary Roux-en-Y Gastric Bypass (P-RYGB), adjustable gastric banding to RYGB (B-RYGB), and sleeve gastrectomy to RYGB (S-RYGB) to determine if primary versus secondary RYGB offer comparable benefits. METHODS: Participating institutions' EMRs and MBSAQIP databases were used to identify adult patients who underwent P-/B-/S-RYGB from 2013 to 2019 with a minimum one-year follow-up. Weight loss and clinical outcomes were assessed at 30 days, 1 year, and 5 years. Our multivariable model controlled for year, institution, patient and procedure characteristics, and excess body weight (EBW). RESULTS: 768 patients underwent RYGB: P-RYGB n = 581 [75.7%]; B-RYGB n = 106 [13.7%]; S-RYGB n = 81 [10.5%]. The number of secondary RYGB procedures increased in recent years. The most common indications for B-RYGB and S-RYGB were weight recurrence/nonresponse (59.8%) and GERD (65.4%), respectively. Mean time from index operation to B-RYGB or S-RYGB was 8.9 and 3.9 years, respectively. After adjusting for EBW, 1 year %TWL (total weight loss) and %EWL (excess weight loss) were greater after P-RYGB (30.4%, 56.7%) versus B-RYGB (26.2%, 49.4%) or S-RYGB (15.6%, 37%). Overall comorbidity resolution was comparable. Secondary RYGB patients had a longer adjusted mean length of stay (OR 1.17, p = 0.071) and a higher risk of pre-discharge complications or 30-day reoperation. CONCLUSION: Primary RYGB offers superior short-term weight loss outcomes compared to secondary RYGB, with decreased risk of 30-day reoperation.

Perioperative use of bispectral (BIS) monitor for a pressure ulcer patient with locked-in syndrome (LIS).

The bispectral (BIS) monitor uses brain electroencephalographic data to measure the depth of sedation and pharmacological response during anaesthetic procedures. In this case, the BIS monitor was used for another purpose, to demonstrate postoperatively to the nursing staff that a patient with history of locked-in syndrome (LIS), who underwent pressure ulcer debridement, had periods of wakefulness and apparent sensation, even with his eyes closed. Furthermore, as patients with LIS can feel pain, despite being unable to move, local block or general anaesthesia should be provided for sharp surgical debridement and other painful procedures. This use of the BIS has shown that as a general rule, the staff should treat the patient as though he might be awake and sensate even if he does not open his eyes or move his limbs. The goal of this study was to continuously monitor pain level and communicate these findings to the entire wound team, i.e. anaesthesiologists, surgeons and nurses.

Regional anaesthesia with sedation protocol to safely debride sacral pressure ulcers.

A treatment challenge for patients with sacral pressure ulcers is balancing the need for adequate surgical debridement with appropriate anaesthesia management. We are functioning under the hypothesis that regional anaesthesia has advantages over general anaesthesia. We describe our regional anaesthesia protocol for perioperative and postoperative management.

Arthroscopic Treatment of Traumatic Hip Dislocation.

Traumatic hip dislocations are high-energy injuries that often result in considerable morbidity. Although appropriate management improves outcomes, associated hip pathology may complicate the recovery and lead to future disability and pain. Historically, open reduction has been the standard of care for treating hip dislocations that require surgical intervention. The use of hip arthroscopy to treat the sequelae and symptoms resulting from traumatic hip dislocations recently has increased, however. When used appropriately, hip arthroscopy is a safe, effective, and minimally invasive treatment option for intra-articular pathology secondary to traumatic hip dislocation.
