Improving Nausea and Vomiting Post-Elipse Balloon: a Novel Single-Dose Regimen of 300 mg Netupitant/0.5 mg Palonosetron Hydrochloride

Impact of body weight-based dosing of palonosetron and ondansetron on postoperative nausea and vomiting following laparoscopic sleeve gastrectomy: a randomized, double-blind study

BACKGROUND

Postoperative nausea and vomiting (PONV) is a frequent adverse effect following laparoscopic sleeve gastrectomy. Palonosetron with a standard dosing (75 μg) schedule has been questioned due to its low efficiency in obese patients. This study aimed to investigate the effectiveness and safety of the body weight-based dosing of palonosetron in managing PONV following laparoscopic sleeve gastrectomy.

METHODS

A single-center, prospective, double-blinded randomized study was conducted between August 2021 and December 2021. Patients who underwent laparoscopic sleeve gastrectomy were prospectively recruited in the study. One hundred patients were randomly divided into palonosetron (Group P) and ondansetron (Group O). The demographic and clinical variables were recorded. The primary outcome of the study was the incidence of PONV between the two groups during the hospitalization. The secondary outcomes were the number of rescue anti-emetic and analgesic medications and the Functional Living Index-Emesis scores.

RESULTS

There were 50 patients in each group (Group P and Group O). There were significant differences in the scores of POVN, nausea, and vomiting favoring Group P. In Group P, the rate of patients using rescue anti-emetics was significantly lower. The incidence of complete response and proportion of patients with higher Functional Living Index-Emesis scores were significantly higher in patients using palonosetron.

CONCLUSIONS

The use of palonosetron significantly reduced the incidence of PONV following laparoscopic sleeve gastrectomy. There was a significant improvement in the scores of Functional Living Index-Emesis in patients using palonosetron.

Safety and Efficacy of 12-Month Intra-gastric Balloon-Series of over 1100 Patients

BACKGROUND

Intra-gastric balloons (IGB) are a mainstay of endoscopic treatment of overweight and obesity. In recent years, an IGB which can remain in situ for 12 months has been developed. The current study aimed to analyse the safety and efficacy of this 12-month IGB.

METHODS

Consecutive patients receiving the Orbera 365TM IGB (Apollo Endosurgery, TX, USA) between September 2017 and August 2021 were included in a prospective database. Patients received regular follow-up consultations followed by endoscopic removal at 12 months. Demographic data along with weight loss data were collected. All adverse events were recorded.

RESULTS

In total, 1149 patients were included in the study. A majority of the patients were female (87.13%). Median body mass index (BMI) prior to insertion was 36.30 kg/m2 (IQR 32.60-40.00 kg/m2). Median absolute weight loss for all patients was 11.36 kg (IQR 6.70-16.82 kg). There was ongoing sustained weight loss until device removal at week 52. For patients with a weight recording at point of IGB removal, median weight loss was greater (15.88 kg, IQR 10.43-21.72) with percentage total body weight loss of 15.38% (IQR 10.99-21.77) and excess weight loss of 53.99% (IQR 32.44-76.30). Increased patient engagement with post-procedural follow-up was associated with increased weight loss (p<0.001). There were 60 total complications (5.22%). Fifty patients required balloon removal due to intolerance. There were eight cases of balloon rupture. There were only two severe complications (0.17%).

CONCLUSION

The current study has confirmed safety of this IGB at 12 months with adverse events comparable to published literature. Weight loss increased up until the point of removal at 12 months.

Endoscopic Procedures for Weight Loss

PURPOSE OF REVIEW

To provide updated evidence on the endoscopic procedures for weight loss and to bring personal insights on the future of endobariatrics.

RECENT FINDINGS

Intragastric balloons promote significant improvement in histologic and radiologic aspects of non-alcoholic steatohepatitis; the endoscopic sleeve gastroplasty is effective up to 5 years and seems particularly beneficial to patients with BMI≤40kg/m²; distal POSE is a promising technique but still lacks adequate clinical data; aspiration therapy triggers remarkable weight loss, but data on weight trends after removal of the device are still lacking; the satiety-inducing device, the sleeveballoon, the gastric mucosal devitalization, and the endoscopic magnetic partial jejunal diversion are promising procedures still under study and refinements. Several therapeutic options are necessary during obesity's natural history. Therefore, endobariatrics should act in harmony with lifestyle interventions, diet modification, psychological treatment, pharmacotherapy, and bariatric surgery seeking the best outcome in the long term.

Risk factors of postoperative nausea and vomiting after total hip arthroplasty or total knee arthroplasty: a retrospective study

Background

Postoperative nausea and vomiting (PONV) is a common complication after total hip/knee arthroplasty (THA/TKA) that affects patient satisfaction and postoperative recovery. It has been reported that patients undergoing THA/TKA experience PONV at a frequency of 20–83%. This study investigates the occurrence of PONV in patients and analyzes the risk factors.

Methods

Patients undergoing primary THA/TKA under general anesthesia from October 1, 2017, to May 1, 2018, were included. Data on patient-related factors were collected before THA/TKA. Anesthesia- and surgery-related factors were recorded postoperatively. Risk factors were analyzed using binary logistic regression.

Results

A stronger association of motion sickness and PONV was found at six hours after bilateral THA/TKA [nausea: odds ratio (OR) =14.648, 3.939–54.470; vomiting: OR =8.405, 2.482–28.466]. At 6–24 hours after bilateral THA/TKA, patients who had a history of migraines tended to experience nausea (OR =12.589, 1.978–80.105). Patients with lower body mass index (BMI) were more likely to experience PONV at 24–72 hours (nausea: OR =0.767, 0.616–0.954; vomiting: OR =0.666, 0.450–0.983) after bilateral THA/TKA.

Conclusions

The incidence of PONV after primary bilateral THA/TKA was higher than that after unilateral THA/TKA. The risk factors vary at different time points after surgery, and a history of motion sickness is the most critical factor affecting PONV.

Efficacy of Intragastric Balloon Placement and Botulinum Toxin Injection in Bariatric Endoscopy

BACKGROUND

To evaluate the results obtained from the combination of intragastric botulinum toxin A (IGBTA), intragastric balloon (IGB), and IGBTA(+)IGB in the treatment of obesity.

MATERIALS AND METHODS

Three separate treatment groups were set up. IGBTA, IGB, and IGBTA(+)IGB were administered to Group 1, 2, and 3, respectively. The body mass indexes (BMI) of patients were measured before and 6 months after the treatment. The intragroup and intergroup treatment results have been evaluated. P<0.05 was considered significant.

RESULTS

The mean BMI decreased by 1.6 kg/m in 40 patients who received IGBTA in group 1 (P<0.001), 3.95 kg/m in 42 patients who received IGB in group 2 (P<0.001), and 4.9 kg/m in 39 patients who received IGBTA and IGB in group 3 (P<0.001) after 6 months of treatment. The intolerance because of the application was the highest in group 3, followed by group 2.

CONCLUSION

The treatment was most successful in group 3 followed by group 2 and group 1, respectively. The authors recommend the group 3 treatment, provided that nausea, vomiting, and flatulence have a high index of probability in such a treatment. However, when deciding between group 1 and group 2 treatments, the authors recommend opting for group 2 treatment that shows to be more efficient.
