Impact of Laparoscopic Banded Gastric Bypass on Weight Loss Surgery Outcomes: 5 Years' Experience.

OBJECTIVE: Evaluate 5-year outcomes of banded gastric bypass (BRYGB) as a primary and conversion bariatric procedure. METHODS: Retrospective review of BRYGB between January 2011and March 2013. Outcomes included percentage of total weight loss (%TWL), weight loss maintenance, and band-related complications. RESULTS: One hundred forty-two patients underwent BRYGB, 106 primary and 36 conversions. Indications for conversion to BRYGB were complications of the primary procedure (n = 19), insufficient weight loss (n = 5), and weight regain (n = 12). In the primary group, mean preoperative BMI was 44.8 kg/m2 (± 6.9 kg/m2). Compared with preoperative weight, mean %TWL was 33.9% (n = 95), 34.1% (n = 82), 34.0% (n = 70), 33.9% (n = 62), and 31.8% (n = 75) after 1, 2, 3, 4, and 5 years, respectively. In conversions secondary to failed primary procedure (insufficient WL and weight regain), mean preoperative BMI was 40.8 kg/m2 (± 6.01 kg/m2). Despite one patient gaining weight, mean %TWL was 25.7% (n = 13), 28% (n = 11), 23.9% (n = 8), 18.3% (n = 8), and 15.1% (n = 12) after 1, 2, 3, 4, and 5 years, respectively. In conversions secondary to primary procedure complications (n = 19), mean preoperative BMI was 28.4 kg/m2 (± 3.5 kg/m2). After 1, 2, 3, 4, and 5 years, mean BMI was 28.1 (n = 15), 29 (n = 10), 29.8 (n = 9), 30.6 (n = 10), and 30.9 (n = 12) kg/m2, respectively. Band-related complications after 5 years: three erosion and five patients complained of persistent dysphagia. One band needed reposition. Perioperative surgical complications: two bleeding, one leakage, one port-site hernia, and one food impaction. CONCLUSION: Banded gastric bypass has good results in terms of weight loss and weight loss maintenance in both primary and conversional bariatric procedures with acceptable incidence of band-related complications.

Fast Track Program in Conversion Bariatric Surgery, as Safe as in Primary Bariatric Surgery?

OBJECTIVES: Evaluate the safety of fast track (FT) surgery program in patients undergoing primary and revisional bariatric surgery (conversion from one procedure to another); identify limiting factors for early discharge and predictive factors for readmission. METHODS: This is a retrospective review of 730 consecutive morbidly obese patients who underwent bariatric surgery between January 2016 and December 2017. Fast track protocol was applied on all patients. Target discharge was after one-night stay. The primary end point is length of stay. The secondary end point is frequency of hospital contact after discharge, readmissions and reinterventions within 30 days. RESULTS: Primary procedures (n = 633) were banded Roux-en-Y gastric bypass (BRYGB, 79.3%), sleeve gastrectomy (10.7%), gastric band (4.7%) and others (5.3%). Mean age (± SD) was 44.32 ± 11.26 years, and mean BMI (± SD) was 43.58 ± 6.12 kg/m2. Conversion procedures (n = 97) were gastric band to BRYGB (40.2%), or to adjustable BRYGB (39.2%), Mason to BRYGB (11.3%), sleeve to BRYGB (4.1%) and others (5.2%). Mean age (± SD) was 47.22 ± 9.1 years, and mean BMI (± SD) was 37.9 ± 7.27 kg/m2. Mean LOS in primary patients was 1.3 ± 0.99, and that in conversion patients was 1.5 ± 1.4. Successful discharge at one night or less was achieved in 650 cases (573 primary and 77 conversion). After one-night discharge, incidence of contact to the hospital, readmission and reintervention was 23.9%, 5.9% and 1.9%, in the primary group and 31.2%, 13% and 5.2% in the conversion group. CONCLUSION: One-night discharge in FT managed conversion procedures is safe, compared to primary procedures. It is associated with higher readmission rates; however, the postdischarge hospital contacts and surgical complications were not statistically significant different.
