Improvement in gastroesophageal reflux disease symptoms after various bariatric procedures: Review of the Bariatric Outcomes Longitudinal Database☆

BACKGROUND The prevalence of gastroesophageal reflux disease (GERD) in the morbidly obese population is as high as 45%. The objective of this study was to compare the efficacy of various bariatric procedures in the improvement of GERD. METHODS The Bariatric Outcomes Longitudinal Database is a prospective database of patients who undergo bariatric surgery by a participant in the American Society of Metabolic and Bariatric Surgery Center of Excellence program. GERD is graded on a 6-point scale, from 0 (no history of GERD) to 5 (prior surgery for GERD). Patients with GERD severe enough to require medications (grades 2, 3, and 4) from June 2007 to December 2009 are identified; the resolution of GERD is noted based on 6-month follow-up. RESULTS Of a total of 116,136 patients, 36,938 patients had evidence of GERD preoperatively. After excluding patients undergoing concomitant hiatal hernia repair or fundoplication, there were 22,870 patients with 6-month follow-up. Mean age was 47.6±11.1 years, with an 82% female population. Mean BMI was 46.3±8.0 kg/m(2). Mean preoperative GERD score for patients with Roux-en-Y gastric bypass (RYGB) was 2.80±.56, and mean postoperative score was 1.33±1.41 (P<.0001). Similarly, adjustable gastric banding (AGB, 2.77±.57 to 1.63±1.37, P<.0001) and sleeve gastrectomy (SG, 2.82±.57 to 1.85±1.40, P<.0001) had significant improvement in GERD score. GERD score improvement was best in RYGB patients (56.5%; 7955 of 14,078) followed by AGB (46%; 3773 of 8207) and SG patients (41%; 240 of 585). CONCLUSION All common bariatric procedures improve GERD. Roux-en-Y gastric bypass is superior to adjustable gastric banding and sleeve gastrectomy in improving GERD. Also, the greater the loss in excess weight, the greater the improvement in GERD score.

Validation that a 1-year fellowship in minimally invasive and bariatric surgery can eliminate the learning curve for laparoscopic gastric bypass

BackgroundThe concept that advanced surgical training can reduce or eliminate the learning curve for complex procedures makes logical sense but is difficult to verify and has not been tested for laparoscopic Roux-en-Y gastric bypass (LRYGB). We sought to determine if minimally invasive/bariatric surgery fellowship graduates (FGs) would demonstrate complication-related outcomes (CRO) equivalent to the outcomes achieved during their training experience under the supervision of experienced bariatric surgeons.MethodsWe compared CRO for the first 100 consecutive LRYGBs performed in practice by five consecutive minimally invasive/bariatric fellows at new institutions (total 500 cases) to CRO for the 611 consecutive LRYGBs performed during their fellowship training experience under the supervision of three experienced bariatric surgeons at the host training institution.ResultsThe two patient groups did not differ demographically. The 18 types of major and minor complications identified after LRYGB did not differ among the five fellowship graduates. The mentors’ CRO were compatible with published benchmark data. As compared with the training institution data, the overall incidence of complications for the combined experience of fellowship graduates did not differ statistically from that of the mentors. The fellowship graduates’ early experience included zero nongastrojejunostomy leaks (0% versus 1.5%) and a low rate of anastomotic stricture (0.8% versus 3.0%), incisional hernia (1% versus 4.4%), bowel obstruction (0% versus 3%), wound infection (0.3% versus 3.1%), and gastrointestinal hemorrhage (0.2% versus 1.6%). The rate of gastrojejunostomy leak (1.8% versus 2.6%) and, most importantly, mortality (0.8% versus 0.7%) did not differ between the two groups.ConclusionsFellowship graduates achieved high-quality surgical outcomes from the very beginning of their postfellowship practices, which are comparable to those of their experienced mentors. These data validate the concept that advanced surgical training can eliminate the learning curve often associated with complex minimally invasive procedures, specifically LRYGB.

Differences in outcomes of laparoscopic gastric bypass

BACKGROUND Although several risk factors affecting weight loss outcomes with bariatric procedures have been identified, the effect of age, gender, race, and illness severity on postoperative outcomes of laparoscopic gastric bypass has not been extensively examined. METHODS The University HealthSystem Consortium database is an administrative and financial database that provides information on the inpatient stay. A retrospective analysis of patient outcomes was performed using 4-year discharge data from the University HealthSystem Consortium database. RESULTS A total of 37,765 patients underwent laparoscopic gastric bypass. The women exhibited significantly reduced mortality, morbidity, intensive care unit (ICU) admissions (9.87% male versus 6.73% female; P <.001), duration of hospitalization (2.72 ± 4.03 d for men versus 2.59 ± 2.88 d for women; P <.001), and hospital costs (

11,170 for women; P <.001). Blacks demonstrated significantly greater 30-day readmission rates, duration of hospitalization, and costs compared with whites. Hispanics had lower ICU admission and hospital costs compared with whites. With increasing age, an increased risk of overall morbidity, ICU admissions, duration of hospitalization, and costs was observed. Compared with the minor severity group, the major/extreme severity group had significantly greater observed mortality, overall morbidity, ICU admissions, duration of hospitalization, and hospital costs. CONCLUSION The present study identified gender, race, age, and illness severity as risk factors affecting postoperative outcomes after laparoscopic gastric bypass. Male gender and increasing age were overall associated with an increased risk of complications. Significant racial disparities in the outcome measures were observed with blacks having an increased risk of adverse events. Illness severity was shown to adversely affect the surgical outcomes in laparoscopic gastric bypass.

Primary and revisional laparoscopic adjustable gastric band placement in patients with hiatal hernia

BackgroundLaparoscopically assisted colon resection has evolved to be a viable option for the treatment of colorectal cancer. This study evaluates the efficacy of hand-assisted laparascopic surgery (HALS) as compared with totally laparoscopic surgery (LAP) for segmental oncologic colon resection with regard to lymph node harvest, operative times, intraoperative blood loss, pedicle length, incision length, and length of hospital stay in an attempt to help delineate the role of each in the treatment of colorectal cancer.MethodsPatient charts were retrospectively reviewed to acquire data for this evaluation. Between June 2001 and July 2005, 40 patients underwent elective oncologic segmental colon resection (22 HALS and 18 LAP). The main outcome measures included lymph node harvest, operative times, intraoperative blood loss, pedicle length, incision length, and length of hospital stay.ResultsThe two groups were comparable in terms of demographics. The tumor margins were clear in all the patients. The HALS resection resulted in a significantly higher lymph node yield than the LAP resection (HALS: 16 nodes; range, 5–35 nodes vs LAP: 8 nodes; range, 5–22 nodes; p < 0.05) and significantly shorter operative times (HALS: 120 min; range, 78–181 min vs LAP: 156 min; range, 74–300 min; p < 0.05). Both groups were comparable with regard to length of hospital stay, pedicle length, and intraoperative blood loss. However, the LAP group yielded a significantly smaller incision for specimen extraction (LAP: 7 cm; range, 6–8 cm vs HALS: 5.5 cm; range, 5–7 cm; p < 0.05).ConclusionThe findings suggest that hand-assisted laparoscopic oncologic segmental colonic resection is associated with shorter operative times, more lymph nodes harvested, and equivalent hospital stays, pedicle lengths, and intraoperative blood losses as compared with the totally laparoscopic approach. The totally laparoscopic technique was completed with a smaller incision. However, this less than 1 cm reduction in incision length has doubtful clinical significance.

The patterns and costs of the Da Vinci robotic surgery system in a large academic institution

BackgroundThe role of laparoscopic hiatal hernia repair (LHHR) at the time of laparoscopic Roux-en-y gastric bypass (LRYGB) is still debatable. This study aims to assess the safety of concomitant LHHR with LRYGB.MethodsThis study is a multi-center, retrospective analysis of a large administrative database. The University Health System Consortium (UHC) is a group of 112 academic medical centers and 256 of their affiliated hospitals. The UHC database was queried using International Classification of Diseases—9 codes and main outcome measures were analyzed.ResultsFrom October 2006 to January 2010, we found 33,717 patients who underwent LRYGB and did not have a hiatal hernia. In this same time period, 644 patients underwent concomitant LRYGB and LHHR, while 1,589 patients underwent LRYGB without repair of their hiatal hernias. On comparison of patients undergoing LRYGB with simultaneous LHHR with those who underwent LRYGB without a diagnosis of HH, there was no significant difference in mortality, morbidity, length of stay (LOS), 30-day readmission, or cost shown. On comparison of patients with HH who underwent LRYGB and simultaneous LHHR with those who had LRYGB without LHHR, no significant difference with regards to all the outcome measures was also shown.ConclusionsIn conclusion, concomitant hiatal hernia repair with LRYGB appears to be safe and feasible. These patients did not have any significant differences in morbidity, mortality, LOS, readmission rate, or cost. Randomized controlled studies should further look into the benefit of hiatal hernia repair in regards to reflux symptoms and weight loss for LRYGB patients.
