Hepatopathy Associated With Type 1 Diabetes: Distinguishing Non-alcoholic Fatty Liver Disease From Glycogenic Hepatopathy

Autoimmune destruction of pancreatic β-cells results in the permanent loss of insulin production in type 1 diabetes (T1D). The daily necessity to inject exogenous insulin to treat hyperglycemia leads to a relative portal vein insulin deficiency and potentiates hypoglycemia which can induce weight gain, while daily fluctuations of blood sugar levels affect the hepatic glycogen storage and overall metabolic control. These, among others, fundamental characteristics of T1D are associated with the development of two distinct, but in part clinically similar hepatopathies, namely non-alcoholic fatty liver disease (NAFLD) and glycogen hepatopathy (GlyH). Recent studies suggest that NAFLD may be increasingly common in T1D because more people with T1D present with overweight and/or obesity, linked to the metabolic syndrome. GlyH is a rare but underdiagnosed complication hallmarked by extremely brittle metabolic control in, often young, individuals with T1D. Both hepatopathies share clinical similarities, troubling both diagnosis and differentiation. Since NAFLD is increasingly associated with cardiovascular and chronic kidney disease, whereas GlyH is considered self-limiting, awareness and differentiation between both condition is important in clinical care. The exact pathogenesis of both hepatopathies remains obscure, hence licensed pharmaceutical therapy is lacking and general awareness amongst physicians is low. This article aims to review the factors potentially contributing to fatty liver disease or glycogen storage disruption in T1D. It ends with a proposal for clinicians to approach patients with T1D and potential hepatopathy.

Spigelian hernia: current approaches to surgical treatment-a review

BACKGROUND

Spigelian hernias (SpH) belong to the group of eponymous abdominal wall hernias. Major reasons for diagnostic difficulties are its low incidence reaching maximum 2% of abdominal wall hernias, a specific anatomical localization with intact external oblique aponeurosis covering the hernia sac and non-constant clinical presentation.

METHODS

A literature review was completed to summarize current knowledge on surgical treatment options and results.

RESULTS

SpH presents a high incarceration risk and therefore should be operated upon even if the patient is asymptomatic. Both laparoscopic and open repair approaches are validated by current guidelines with lesser postoperative complications and shorter hospital stay in favour of minimally invasive surgery, regardless of the technique used. Overall recurrence rate is very low.

CONCLUSION

All diagnosed SpH should be planned for elective operation to prevent strangulated hernia and, therefore emergency surgery. Both open and laparoscopic SpH treatment can be safely performed, depending on surgeon's experience. In most cases, a mesh repair is generally advised.
