Multimodal approach utilising a weight management programme prior to bariatric surgery in patients with BMI ≥50 kg/m2: A propensity score matching retrospective cohort study.

We evaluated preoperative weight loss and days from initial consult to surgery in patients with BMI ≥50 kg/m2 who were and were not enrolled in medical weight management (MWM) prior to laparoscopic sleeve gastrectomy. We retrospectively identified patients with BMI ≥50 kg/m2 who had primary sleeve gastrectomy between 2014 and 2019 at two bariatric surgery centres in our healthcare system. Patients presenting after 2017 that received preoperative MWM (n = 28) were compared to a historical cohort of non-MWM patients (n = 118) presenting prior to programme initiation in 2017 on preoperative percent total body weight loss (%TBWL) and days from initial consult to surgery. A total of 151 patients (MWM, 33; non-MWM, 118) met inclusion criteria. BMI was significantly greater in MWM versus non-MWM (p = .018). After propensity score matching, median BMI at initial consult in non-MWM versus MWM no longer differed (p = .922) neither were differences observed on the basis of weight, age, sex, race or ethnicity. After PSM, MWM had significantly lower BMI at surgery (p = .018), lost significantly more weight from consult to surgery (p < .001) and achieved significantly greater median %TBWL from consult to surgery (p < .001). We noted no difference between groups on 6-month weight loss (p = .533). Days from initial consult to surgery did not differ between groups (p < .863). A preoperative MWM programme integrated into multimodal treatment for obesity in patients with a BMI ≥50 kg/m2 resulted in clinically significant weight loss without prolonging time to surgery.

Five-year outcomes of revisional bariatric surgery: gastric band to sleeve gastrectomy or to Roux-en-Y gastric bypass.

BACKGROUND: Revisional bariatric surgery after an index adjustable gastric band (AGB) may be indicated to remedy weight relapse or band-related complications. We examined outcomes five years following revision from AGB to laparoscopic sleeve gastrectomy (AGB-LSG) or to Roux-en-Y gastric bypass (AGB-RYGB). METHODS: We conducted a retrospective review to identify patients (men and women, age 18-80) who underwent one revisional bariatric procedure with AGB as the index procedure at two medical centers in our healthcare system between January 2012 and February 2017. We only included patients with a pre-revision BMI > 30 kg/m2 for whom 5-year follow-up data were available. We compared 5-year weight loss and remission of comorbidities in patients undergoing AGB-LSG and AGB-RYGB conversion. RESULTS: A total of 114 patients met inclusion criteria (65 AGB-LSG, 49 AGB-RYGB). At 5-year post-revision, percent total weight loss (3.4% vs 19.9%; p < 0.001), percent excess weight loss (7.0% vs 50.8%; p < 0.001) and decrease in BMI (1.5 vs 8.8; p < 0.001) was greater in AGB-RYGB vs. AGB-LSG. No significant difference in remission or development of new comorbidities was observed. CONCLUSION: Conversion of AGB to RYGB is associated with superior intermediate-term weight loss compared to conversion of AGB to LSG. Future multicenter studies with larger sample sizes are necessary to further describe the intermediate-term outcomes of revisional bariatric surgery.

Fifty-five consecutive laparoscopic appendectomy procedures without conversion.

BACKGROUND: In patients with suspected appendicitis, laparoscopic appendectomy is gaining increasing acceptance primarily because it is associated with less postoperative pain and a shorter hospital stay. Experience with 55 consecutive laparoscopic appendectomies, performed without conversion by the same surgeon, is herein examined and analyzed. METHODS: The medical records of 55 consecutive patients with suspected appendicitis who underwent laparoscopic exploration (from 2000 to 2002) were analyzed for demographic information, clinical findings, laboratory/computed tomography scan results, intraoperative diagnosis, clinicopathologic correlation, complications, incidental findings, and operative time. RESULTS: Twenty-six males (47%) and 24 females (53%) underwent surgery. Mean age was 25.2 years (range, 6 years to 67 years). Computerized tomography scans obtained in 37 cases (74%) had a sensitivity of 86.7% and a specificity of 62.5%. Average length of stay was 2.3 days (median, 1 day). Average operating room time was 69 minutes (range, 40 to 173 minutes). Five patients experienced postoperative complications: 2 had intraperitoneal abscesses, 1 had urinary retention, and 2 had postoperative ileus. No operative conversions or postoperative wound infections occurred. CONCLUSION: Laparoscopy confirmed the clinical diagnosis of acute appendicitis and allowed the safe, effective treatment of both complicated and uncomplicated appendicitis with minimal hospitalization, recovery and convalescent times, and zero open conversion and wound infections. Laparoscopic appendectomy is advocated as the procedure of choice for patients with clinically suspected appendicitis.

Vein Harvest: Minimally Invasive Techniques and Reduction in Complications.

Revascularization of the coronary or lower extremity circulation ideally requires an autologous conduit. The saphenous vein is the most commonly used graft. Minimally invasive surgical techniques for harvesting of the greater saphenous vein (GSV) are gaining popularity. With better instruments, critical evaluation of techniques and longer follow-up of patients, the outcome of such vein harvesting is improving. An increasing number of authors are reporting a variety of techniques with reduction in wound complications compared to conventional surgery.
