Our short-term experience with LESS TEP inguinal hernia repair has shown that in experienced hands, inguinal hernia repair via the LESS TEP technique is as safe as the standard TEP technique. However, based on our evidence, we currently believe that the LESS TEP technique is not an efficacious surgical alternative to the standard TEP technique for inguinal hernias.

Primary aldosteronism (PA) is a common form of secondary hypertension and has significant cardiovascular consequences. Mutated channelopathy due to the activation of calcium channels has been recently described in aldosterone-producing adenoma (APA). The study involved 148 consecutive PA patients, (66 males; aged 56.3 ± 12.3years) who received adrenalectomy, and were collected from the Taiwan PA investigator (TAIPAI) group. A high rate of somatic mutation in APA was found (n = 91, 61.5%); including mutations in KCNJ5 (n = 88, 59.5%), ATP1A1 (n = 2, 1.4%), and ATP2B3 (n = 1, 0.7%); however, no mutations in CACNA1D were identified. Mutation-carriers were younger (<0.001), had lower Cyst C (p = 0.042), pulse wave velocity (p = 0.027), C-reactive protein (p = 0.042) and a lower rate of proteinuria (p = 0.031) than non-carriers. After multivariate adjustment, mutation carriers had lower serum CRP levels than non-carriers (p = 0.031. Patients with mutation also had a greater chance of recovery from hypertension after operation (p = 0.005). A high incidence of somatic mutations in APA was identified in the Taiwanese population. Mutation-carriers had lower CRP levels and a higher rate of cure of hypertension after adrenalectomy. This raises the possibility of using mutation screening as a tool in predicting long-term outcome after adrenalectomy.

This homemade transumbilical port offers a safe, reliable, flexible, and cost-effective access for LESS procedures. This technique may be an alternative for current specialized port systems.

The clinical characteristics and outcomes in patients with clinical aldosterone-producing adenomas harboring KCNJ5 mutations with or without subclinical hypercortisolism remain unclear. This prospective study is aimed at determining factors associated with subclinical hypercortisolism in patients with clinical aldosterone-producing adenomas. Totally, 82 patients were recruited from November 2016 to March 2018 and underwent unilateral laparoscopic adrenalectomy with at least a 12-month follow-up postoperatively. Standard subclinical hypercortisolism (defined as cortisol >1.8 μg/dL after 1 mg dexamethasone suppression test [DST]) was detected in 22 (26.8%) of the 82 patients. Intriguingly, a generalized additive model identified the clinical aldosterone-producing adenoma patients with 1 mg DST>1.5 μg/dL had significantly larger tumors ( P =0.02) than those with 1 mg DST<1.5 μg/dL. Multivariable logistic regression showed that the presence of KCNJ5 mutations (odds ratio, 0.22, P =0.010) and body mass index (odds ratio, 0.87, P =0.046) were negatively associated with 1 mg DST>1.5 μg/dL, whereas tumor size was positively associated with it (odds ratio, 2.85, P =0.014). Immunohistochemistry revealed a higher degree of immunoreactivity for CYP11B1 in adenomas with wild-type KCNJ5 ( P =0.018), whereas CYP11B2 was more commonly detected in adenomas with KCNJ5 mutation ( P =0.007). Patients with wild-type KCNJ5 and 1 mg DST>1.5 μg/dL exhibited the lowest complete clinical success rate (36.8%) after adrenalectomy. In conclusion, subclinical hypercortisolism is common in clinical aldosterone-producing adenoma patients without KCNJ5 mutation or with a relatively larger adrenal tumor. The presence of serum cortisol levels >1.5 μg/dL after 1 mg DST may be linked to a lower clinical complete success rate.

Minilaparoscopic herniorrhaphy was superior to open repair with regard to prevention of contralateral hernia occurrence and overall satisfaction.

Minilaparoscopic herniorrhaphy with hernia sac transaction is a safe and effective technique in children and young adults with indirect inguinal hernias.

The preliminary results show that LESS retroperitoneal adrenalectomy is a safe and feasible procedure for functional adrenal tumors using standard laparoscopic instruments.
