Mistakes in bariatric surgery and how to avoid them

Francesco Saverio Papadia, Gianni Camerini

Summary

AI Generated

This material discusses common mistakes in managing bariatric surgery patients across preoperative, perioperative, and postoperative periods, acknowledging that high-level evidence is lacking for many aspects of surgical bariatric care.

Bariatric surgery is accepted as a safe and effective treatment for morbid obesity and has gained widespread popularity over the past two decades.
Advancements in surgical techniques, perioperative care, and fellowship-based training have substantially reduced morbidity and mortality rates.
Several controversial aspects of surgical treatments for morbidly obese patients remain to be considered.
The discussion is based on clinical experience rather than high-level evidence, which is lacking for many aspects of surgical bariatric care.
This content would benefit clinicians involved in the care of bariatric surgery candidates and postoperative patients.

Abstract

Nowadays, obesity represents an immense burden for global healthcare. The number of overweight or obese cases has exceeded that of underweight individuals.1 Bariatric surgery is accepted as a safe and effective treatment for patients with morbid obesity and has gained widespread popularity in the past two decades. Advancements in surgical techniques, perioperative care, and fellowship-based bariatric surgery training have substantially reduced morbidity and mortality rates. Nevertheless, several controversial aspects of surgical treatments of morbidly obese patients are still to be considered. Here we discuss the mistakes made when managing patients who are candidates for or have been submitted to bariatric surgery in the preoperative, perioperative, and postoperative periods. As high-level evidence is lacking for many aspects of surgical bariatric care, the discussion is based on our long-standing clinical experience.

Abstract

Abdominal distension and bloating are among the most frequently misunderstood complaints in gastroenterology. They are often used as interchangeable terms, a conceptual mistake that continues to drive diagnostic errors and ineffective treatment. According to Rome IV, bloating and distension may represent either a primary disorder of gut–brain interaction (DGBI) or occur as symptoms with other DGBIs, such as irritable bowel syndrome (IBS), functional dyspepsia (FD) or functional constipation (FC).

Abstract

The coordination of smooth muscle and nerve function in the gastrointestinal tract is crucial for digestion and waste disposal. Disorders in this process can lead to chronic intestinal pseudo-obstruction (CIPO), a severe condition where the intestines fail to propel contents. Managing CIPO involves improving intestinal motility, maintaining nutrition, treating complications, managing exacerbations, and carefully considering invasive procedures. This article focuses on common mistakes in CIPO diagnosis and management, offering evidence-based insights and clinical experience.

Abstract

Ostomy management refers to the care and maintenance of an ostomy and involves various aspects to ensure the individual’s health, comfort, and quality of life. This should involve the patient, a close support system (family and/or friends), and a healthcare team, including ostomy nurses and healthcare professionals specialising in ostomy care.

Abstract

Biological therapy has revolutionised the treatment of moderate to severe inflammatory bowel disease (IBD), namely Crohn’s disease (CD) and ulcerative colitis (UC). However, up to one-third of patients with IBD are primary non-responders, and up to half can lose response over time.These unwanted outcomes can be explained by either pharmacodynamic (mechanistic failure) or pharmacokinetic (PK) issues with or without the development of anti-drug antibodies (ADA), so-called immunogenicity.1 Reactive therapeutic drug monitoring (TDM), defined as the measurement of drug concentrations and anti-drug antibody (ADA) levels in the setting of primary non-response (PNR) or secondary loss of response (SLR), can help to explain better and manage these unwanted outcomes. However, it would make sense to try to prevent PNR and SLR by routinely measuring drug concentrations and ADA to achieve and maintain a targeted therapeutic drug concentration, the so-called proactive TDM. Here we discuss some common mistakes and significant errors to avoid when utilising TDM of biologics in patients with IBD. The discussion is based on evidence, whenever possible, and our clinical experience and perception of the field.
