A comparison of thromboembolic and bleeding events following laparoscopic gastric bypass in patients treated with prophylactic regimens of unfractionated heparin or enoxaparin
Introduction:
We prospectively evaluated 30-day thromboembolic and bleeding events in 2 groups of laparoscopic gastric bypass patients receiving different anticoagulation regimens.
Methods:
The first cohort of patients received enoxaparin 40 mg subcutaneously preoperatively, 40 mg subcutaneously on postoperative day 0, and twice daily until discharge. The second cohort of patients received unfractionated heparin 5,000 units subcutaneously preoperatively, nothing on postoperative day 0, and 5,000 units 3 times per day until discharge.
Results:
The incidence of deep venous thrombosis in both cohorts was 0. There was 1 pulmonary embolism in the heparin cohort (P =3D .999). Fourteen patients (5.9%) in the enoxaparin cohort required postoperative transfusions compared with 3 patients (1.3%) in the heparin cohort (P =3D .011). Four patients (1.7%) in the enoxaparin cohort required re-exploration for bleeding.
Conclusion:
Both enoxaparin and heparin are effective at preventing thromboembolic events following laparoscopic gastric bypass. Heparin is the preferred agent due to the excessive bleeding complications encountered with enoxaparin
Resolution of Fundic Gland Polyposis following Laparoscopic Magnetic Sphincter Augmentation and Subsequent Cessation of Proton Pump Inhibitors
Gastric polyps occur from a variety of sources and are found commonly on upper endoscopy. We present the case of a 49-year-old female who presented for evaluation for antireflux surgery with a history of fundic gland polyposis who required twice-daily proton pump inhibitors (PPIs) for control of her gastric reflux. After verifying that she met criteria for surgery, she underwent an uncomplicated laparoscopic magnetic sphincter augmentation placement. With the cessation of PPIs following surgery, the fundic gland polyposis resolved. Fundic gland polyps may occur sporadically or within certain syndromes, such as familial adenomatous polyposis. Multiple possible inciting factors exist, including the use of PPIs. This is the first reported case of the resolution of numerous fundic gland polyps following the completion of laparoscopic magnetic sphincter augmentation
American Society for Metabolic and Bariatric Surgery 2018 estimate of metabolic and bariatric procedures performed in the United States.
BACKGROUND: Metabolic and bariatric surgery, despite being the only effective durable treatment for obesity, remains underused as approximately 1% of all patients who qualify undergo surgery. The American Society for Metabolic and Bariatric Surgery created a Numbers Taskforce to specify annual rate of utilization for obesity treatment interventions and to determine if patients in need are receiving appropriate therapy.
OBJECTIVES: The objective of this study was to provide the best estimated number of metabolic and bariatric procedure performed in the United States in 2018.
SETTING: United States.
METHODS: We reviewed data from the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program, National Surgical Quality Improvement Program, Bariatric Outcomes Longitudinal Database, and Nationwide Inpatient Sample. In addition, data from industry and outpatient centers were used to estimate outpatient center activity. Data from 2018 were compared mainly with data from the previous 2 years.
RESULTS: Compared with 2017, the total number of metabolic and bariatric procedures performed in 2018 increased from approximately 228,000 to 252,000. The sleeve gastrectomy continues to be the most common procedure. The gastric bypass procedure trend remained relatively stable and the gastric band procedure trend continued to decline. The percentage of revision procedures and biliopancreatic diversion with duodenal switch procedures increased slightly. Finally, intragastric balloons placement continues as a significant contributor to the cumulative total number of procedures performed but declined from the previous year.
CONCLUSIONS: There was a 10.8% increase in the number of metabolic and bariatric procedures performed in 2018, compared with 2017, with an overall increase of approximately 60% since 2011. When taking into account primary procedures only, approximately 1.1% of patients who qualified for metabolic and bariatric surgery were treated with surgery in 2018
Validation that a 1-year fellowship in minimally invasive and bariatric surgery can eliminate the learning curve for laparoscopic gastric bypass
The 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.
We 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.
The 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.
Fellowship 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
