Whereas for TEP the guidelines do not recommend mesh fixation on the basis of meta-analyses regardless of the defect size, for TAPP mesh fixation can be omitted only up to a defect size of 3 cm because of the paucity of studies on this topic. Hence, this study now seeks to explore this subject on the basis of prospective data from the Herniamed Hernia Registry. In the period September 01, 2009, to January 31, 2014, 11,228 male patients were operated on with the TAPP technique for a primary unilateral inguinal hernia and were followed up for 1 year. ⋯ For TAPP repair of an inguinal hernia, mesh fixation is not necessary in a significant number of patients. Patients with a medial and combined hernia are at higher risk of recurrence. In the patient series analyzed, it was possible to significantly reduce the recurrence rate with mesh fixation and larger mesh size for medial defects.

Case Reports
Spleen and splenic vessel preserving distal pancreatectomy for bifocal PNET in a young patient with MEN1.
MEN1 patients requiring resection of neuroendocrine tumors (pNET) are frequently young, active patients in whom a minimal access approach minimizes perioperative morbidity and splenic preservation decreases the risk of post-splenectomy sepsis. Laparoscopic spleen preserving distal pancreatectomy can be performed with removal (Warshaw's technique) or preservation of the splenic vessels, the later having a higher rate of successful splenic preservation. ⋯ Improvements in laparoscopic techniques and technology have enabled surgeons to preserve the major splenic vessels to avoid splenic infarcts, abscesses and re-operations, and minimize the risk of left-sided portal hypertension. Splenic preservation is particularly important in young MEN1 patients undergoing laparoscopic pancreatectomy for pNET due to the increased risk of overwhelming post-splenectomy sepsis.

Bacterial overgrowth is common complication of short bowel syndrome (SBS) and is a result of an impaired gut barrier function. Toll-like receptor 4 (TLR4) is crucial in maintaining intestinal epithelial homeostasis, participates in a vigorous signaling process and heightens inflammatory cytokine output. The objective of this study was to determine the effects of bowel resection on TLR4 signaling in intestinal mucosa in a rat model. ⋯ In a rat model of SBS, elevated intestinal BT is associated with a stimulated TLR4 signaling.

Review Meta Analysis
Revaluation of the efficacy of magnetic sphincter augmentation for treating gastroesophageal reflux disease.
Gastroesophageal reflux disease (GERD) is a prevalent disease which severely impacts the quality of life of the patients. The surgical options are limited to such patients who are not satisfied with medical therapies. Magnetic sphincter augmentation (MSA) is a new antireflux surgical technique for treating GERD, which could physiologically reinforce the lower esophageal sphincter by magnetic force. Many clinical and animal studies have focused on this new therapy. The purpose of this work was to review the feasibility, efficacy and safety of MSA as a new treatment for GERD. ⋯ MSA (or LINX) devices provide an alternative surgical option for the patients who had failed in medical therapy. This review of the current literatures demonstrates that MSA is as effective as the medical and conventional surgical therapies. In the future, MSA will play a more important role in the treatment of GERD because of its unique advantage.

Multicenter Study
Incidence, risk factors and consequences of bile leakage following laparoscopic major hepatectomy.
Bile leakage (BL) remains a common cause of major morbidity after open major liver resection but has only been poorly described in patients undergoing laparoscopic major hepatectomy (LMH). The present study aimed to determine the incidence, risk factors and consequences of BL following LMH. ⋯ After LMH, BL occurred in 13.5 % of the patients and was associated with significant morbidity. Patients with one or several risk factors for BL should benefit intra-operative drain placement.
