Economic analysis of the robotic approach to inguinal hernia versus laparoscopic: is it sustainable for the healthcare system?

INTRODUCTION: There has been a rapid proliferation of the robotic approach to inguinal hernia, mainly in the United States, as it has shown similar outcomes to the laparoscopic approach but with a significant increase in associated costs. Our objective is to conduct a cost analysis in our setting (Spanish National Health System). MATERIALS AND METHODS: A retrospective single-center comparative study on inguinal hernia repair using a robotic approach versus laparoscopic approach. RESULTS: A total of 98 patients who underwent either robotic or laparoscopic TAPP inguinal hernia repair between October 2021 and July 2023 were analyzed. Out of these 98 patients, 20 (20.4%) were treated with the robotic approach, while 78 (79.6%) underwent the laparoscopic approach. When comparing both approaches, no significant differences were found in terms of complications, recurrences, or readmissions. However, the robotic group exhibited a longer surgical time (86 ± 33.07 min vs. 40 ± 14.46 min, p < 0.001), an extended hospital stays (1.6 ± 0.503 days vs. 1.13 ± 0.727 days, p < 0.007), as well as higher procedural costs (2318.63 ± 205.15 € vs. 356.81 ± 110.14 €, p < 0.001) and total hospitalization costs (3272.48 ± 408.49 € vs. 1048.61 ± 460.06 €, p < 0.001). These results were consistent when performing subgroup analysis for unilateral and bilateral hernias. CONCLUSIONS: The benefits observed in terms of recurrence rates and post-surgical complications do not justify the additional costs incurred by the robotic approach to inguinal hernia within the national public healthcare system. Nevertheless, it represents a simpler way to initiate the robotic learning curve, justifying its use in a training context.

Implanted Closed-Loop Gastric Electrical Stimulation (CLGES) System with Sensor-Based Feedback Safely Limits Weight Regain at 24 Months.

BACKGROUND: Weight regain following bariatric surgery is not uncommon. Safe, effective weight loss treatment up to 1 year has been reported with the closed-loop gastric electrical stimulation (CLGES) system. Continuous recording of eating and activity behavior by onboard sensors is one of the novel features of this closed-loop electrical stimulation therapy, and may provide improved long-term weight maintenance by enhancing aftercare. METHODS: Four centers participating in a 12-month prospective multicenter randomized study monitored all implanted participants (n = 47) up to 24 months after laparoscopic implantation of a CLGES system. Weight loss, safety, quality of life (QOL), and cardiac risk factors were analyzed. RESULTS: Weight regain was limited in the 35 (74%) participants remaining enrolled at 24 months. Mean percent total body weight loss (%TBWL) changed by only 1.5% between 12 and 24 months, reported at 14.8% (95% CI 12.3 to 17.3) and 13.3% (95% CI 10.7 to 15.8), respectively. The only serious device-/procedure-related adverse events were two elective system replacements due to lead failure in the first 12 months, while improvements in QOL and cardiovascular risk factors were stable thru 24 months. CONCLUSION: During the 24 month follow-up, CLGES was shown to limit weight regain with strong safety outcomes, including no serious adverse events in the second year. We hypothesize that CLGES and objective sensor-based behavior data combined to produce behavior change. The study supports CLGES as a safe obesity treatment with potential for long-term health benefits. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT01448785.

A Na+ conducting hydrogel for protection of organic electrochemical transistors.

Organic electrochemical transistors (OECTs) are being intensively developed for applications in electronics and biological interfacing. These devices rely on ions injected in a polymer film from an aqueous liquid electrolyte for their operation. However, the development of solid or semi-solid electrolytes are needed for future integration of OECTs into flexible, printed or conformable bioelectronic devices. Here, we present a new polyethylene glycol hydrogel with high Na+ conductivity which is particularly suitable for OECTs. This novel hydrogel was synthesized using cost-effective photopolymerization of poly(ethylene glycol)-dimethacrylate and sodium acrylate. Due to the high water content (83% w/w) and the presence of free Na+, the hydrogel showed high ionic conductivity values at room temperature (10-2 S cm-1) as characterized by electrochemical impedance spectroscopy. OECTs made using this hydrogel as a source of ions showed performance that was equivalent to that of OECTs employing a liquid electrolyte. They also showed improved stability, with only a 3% drop in current after 6 h of operation. This hydrogel paves the way for the replacement of liquid electrolytes in high performance OECTs bringing about advantages in terms of device integration and protection.

Post-implant Analysis of Epidemiologic and Eating Behavior Data Related to Weight Loss Effectiveness in Obese Patients Treated with Gastric Electrical Stimulation.

OBJECTIVE: To determine possible preoperative predictors for obtaining clinically meaningful weight loss with gastric electrical stimulation (GES) using the "Three-Factor Eating Questionnaire" (TFEQ) as well as epidemiological data. METHODS: Ninety-seven obese participants in a prospective multicenter randomized study conducted in nine European centers were implanted laparoscopically with the abiliti® closed-loop GES system (CLGES). Five clinical variables and three preoperative TFEQ factor scores (F1-cognitive-restraint, F2-disinhibition, and F3-hunger) were analyzed in order to determine predictors of weight loss success defined as excess weight loss (EWL) > 30% and failure defined as EWL < 20% at 12 months post-surgery. RESULTS: The mean 12-month %EWL with CLGES was 35.1 ± 19.7%, with a success rate of 52% and a failure rate of 19%. Significant predictors of success were body mass index (BMI) < 40 kg/m2 and age ≥ 50 years, increasing probability of success by 22 and 29%, respectively. A low F1-cognitive-restraint score was a significant predictor of failure (p = 0.004). The best predictive model for success included F1-cognitive-restraint, F2-disinhibition, BMI < 40, and age ≥ 50 (p = 0.002). CONCLUSION: This retrospective analysis has shown that age, preoperative BMI, and F1-cognitive-restraint and F2-disinhibition scores from a preoperatively administered TFEQ are predictive of weight loss outcomes with CLGES and may be used for patient selection.

La deciduosis se denomina a la implantación de tejido decidual en distintos órganos. Dentro de la cavidad abdominal la deciduosis apendicular es una rara entidad que puede darse durante el periodo gestacional. La clínica derivada de esta puede ser desde procesos inflamatorios o hemorrágicos, como manifestaciones clínicas de abdomen agudo, hasta no asociarse clínica alguna. Informamos del caso de un cuadro de deciduosis con presentación de apendicitis aguda

Deciduosis is defined as implantation of decidual tissue in different organs. Inside the abdominal cavity, appendicular deciduosis is an unusual clinical entity during pregnancy. Clinical presentation may include inflammatory or hemorrhagic processes, which are manifestations of acute abdomen but sometimes symptoms are completely absent. We report a case of deciduosis presenting as acute appendicitis

[Comparison of two types of surgical gastrostomies, open and laparoscopic in home enteral nutrition]. / Comparación entre dos tipos de gastrostomías quirúrgicas, abierta y laparoscópica, en nutrición enteral domiciliaria.

AIM: Exposing the complications of surgical gastrostomies used as way of home enteral nutritional support (HEN) and detecting the differences between the two techniques used in our environment: Open Surgery vs Laparoscopic Surgery. MATERIAL AND METHODS: Retrospective descriptive observational study of the surgical gastrostomies performed between 1994 and 2009 followed up by our unit. Have been analyzed the complications detected in our practice during the follow-up of patients with HEN performed via open laparotomy vs. laparoscopic tecniques, assessing: leaks of gastric fluid to the exterior, abdominal wall irritation, presence of exudate, presence of exudate with positive culture that required antibiotical treatment, burning or loss of substance of the periostomic zone, breach of balloon, decubitus ulcer caused by the tube and formation of granuloma. RESULTS: Between 1994 and 2009, 57 surgical gastrostomies were performed: 47 using the conventional laparotomic (open) tecnique and 10 laparoscopies. The average age of the patients was 57.51 ± 17.29 years old. The most common cause for the performance of surgical gastrostomy was esophageal cancer (38.6%) followed by neurologic alterations (26.3%) and head and neck tumors (26.3%). 97.9% of the patients who underwent to surgical gastrostomy presented at least one complication, meaning that only 2.1% were free of complications; meanwhile, 50% of the patients were laparoscopic gastrostomy was performed had none of these complications. The most common complications were the presence of leaks of gastric fluid and abdominal wall irritation that appeared on 89.4% and 83% respectively of the laparotomic gastrostomies versus the presence of only 30% of both complications in laparoscopic gastrostomies being the difference statistically significant (p < 0.01). CONCLUSIONS: After the introduction of the laparoscopic technique in the performance of surgical gastrostomies has been observed a decrease of the complications occured during the home enteral nutritional support related to surgical gastrostomies.
