Two feared complications of laparoscopic sleeve gastrectomy (LSG) are bleeding and gastric staple line leak. The aim of this study was to evaluate the safety and efficacy of complete gastric staple line bioabsorbable reinforcement to minimize surgical complications in patients undergoing LSG. Data from consecutive patients undergoing LSG were prospectively collected and retrospectively analyzed.

Robotic sleeve gastrectomy (RSG) is gaining place among surgeons. In our initial RSG practice, we noticed that gastric staple line intraoperative bleeding is more frequent and more important compared to the conventional laparoscopic approach. Any technique that could reduce the likelihood of intraoperative bleeding in RSG would be of tremendous benefit.

Artificial intelligence (AI) is transforming the landscape of medicine, including surgical science and practice. The evolution of AI from rule-based systems to advanced machine learning and deep learning algorithms has opened new avenues for its application in metabolic and bariatric surgery (MBS). AI has the potential to enhance various aspects of MBS, including education and training, decision-making, procedure planning, cost and time efficiency, optimization of surgical techniques, outcome and complication prediction, patient education, and access to care.

The worldwide prevalence of type 2 diabetes mellitus (T2DM) is increasing in parallel with obesity. One anastomosis gastric bypass (OAGB) is considered effective to treat both T2DM and obesity. The aim of this study was to evaluate the efficacy of OAGB versus sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB) for treatment of T2DM, analyzing data exclusively from randomized control trials (RCTs).

Background: Obesity is a well-established risk factor for cancer. Laparoscopic sleeve gastrectomy (LSG) is established as a safe procedure providing accelerated weight loss and comorbidity improvement or remission. Additionally, it is approved as a bridging procedure for various non-oncologic surgeries, with very limited data for oncologic procedures.

Background: Gastric staple line leak treatment after laparoscopic sleeve gastrectomy (LSG) remains challenging. Regenerative medicine is gaining place in the accelerated treatment of damaged tissues. This study presents the first series of gastric leak treatment after LSG using endoscopic intragastric administration of combined autologous mesenchymal stem cells (MSC) and platelet-rich plasma (PRP).

Article Synopsis
  • Recent advancements like OpenAI's ChatGPT-4 are being explored for their potential use in bariatric surgery decision-making as obesity rates rise.
  • The study involved a survey of thirty bariatric surgeons who assessed ten patient scenarios, comparing their recommendations with those provided by ChatGPT-4.
  • Results showed that ChatGPT-4 aligned with expert opinions 30% of the time, highlighting inconsistencies and the necessity for human expertise in effective treatment decisions.

This systematic review evaluates the safety and efficacy of Roux-en-Y gastric bypass (RYGB) on weight loss and anti-reflux outcomes when used as a revisional bariatric surgical procedure after failed anti-reflux surgery. A systematic literature search next to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines was performed for articles published by 30 Mar 2022. After examining 416 papers, 23 studies were included (n = 874 patients).

Background: The Essential Surgical Skills Course (ESSC) is a multi-specialty induction "boot camp" style course that has been run successfully for five years. The aim of the current paper is to create an accurate guide for the replication of the course by other teams and assess the course's fitness for purpose, through the survey feedback provided by trainees.

Methods: The course's fitness for purpose was assessed through cumulative five-year survey feedback from trainees.

Background: The most common postoperative complication of laparoscopic sleeve gastrectomy (LSG) is staple-line leak. Even if its rate following LSG has been recently reduced, management of chronic leaks remains challenging.

Objective: To present a series of patients treated with laparoscopic Roux-en-Y fistulojejunostomy (LRYFJ) for chronic gastric leak (>12 wk) post-LSG.

Purpose: Obesity is an independent risk factor for renal injury. A more favorable metabolic environment following weight loss may theoretically lead to improved renal function. We aimed to evaluate the evolution of renal function one year after sleeve gastrectomy in a large prospective cohort of patients with morbid obesity and assess the influence of fat-free mass (FFM) changes.

Introduction: Nonoperative treatment can be attempted for uncomplicated adhesive small bowel obstruction (ASBO), but carries a risk of delayed surgery. Highlighting initial parameters predicting risk of failure of nonoperative management would be of great interest.

Methods: Patients initially managed conservatively for uncomplicated ASBO were retrospectively analyzed.
