Background:
The incidence of perforated peptic ulcers has decreased during the last decades but
the optimal treatment for these patients remains controversial. At the same time, a
laparoscopic approach to this condition has been adopted by an increased number of
surgeons.
Therefore, this study wants to evaluate the postoperative results of the laparoscopic
treatment of perforated peptic ulcer performed in one Italian center with extensive
experience in laparoscopic surgery.

Abstract
BACKGROUND AND OBJECTIVE:
 Lumbar spinal stenosis (LSS) is a common degenerative condition that occurs in the spine with increasing age. Clinically, LSS causes a progressive reduction in walking autonomy, resulting in a poor quality of life and impaired functional capacity. The aim of this study was to evaluate the clinical outcome and quality of life of elderly patients presenting with LSS and associated comorbidities after a 5-year follow-up who were treated with an interspinous process device (IPD).

Over the last few decades, many surgical techniques for lumbar interbody fusion have been reported. The anterior-to-psoas (ATP) approach is theoretically supposed to benefit from the advantages of both anterior and lateral approaches with similar complication rates, even in L5-S1. At this segment, the anterior lumbar interbody fusion (ALIF) requires retroperitoneal dissection and retraction of major vessels, whereas the iliac crest does not allow the lateral transpsoas approach.

in the last three decades, minimally invasive techniques have progressively gained acceptance, as
shown by the numerous studies published in the literature. Before the 1990s, video-assisted thoracoscopic
surgery (VATS) was considered feasible almost exclusively for the diagnosis of pleural diseases. The
availability of better instruments and endoscopic stapling devices allowed thoracoscopy to evolve into a new
“therapeutic era”. Nowadays, VATS is considered the approach of choice for the treatment of pneumothorax

Primary hyperparathyroidism is an endocrine disorder characterized by autonomous production of parathyroid hormone. Patients with the symptomatic disease should be referred for parathyroidectomy. However, the distinction between the pathological condition and the benign one is very challenging in the surgical setting; therefore, accurate recognition is important to ensure success during minimally invasive surgery. At present, all intraoperative techniques significantly increase surgical time and, consequently, cost.

Today, an ever-increasing number of diseases requiring a surgical solution are treated by means of minimally invasive procedures [1]. When possible, these procedures are suggested instead of traditional approaches because they decrease both the surgical risk and postsurgery hospitalization. The growing technological advances in terms of imaging techniques (i.e., visualization of organs and tissues) and handling of the minimally invasive instruments (e.g., endoscopes) play a key role in improving the qualitative aspects of the interventions [2].

BACKGROUND:
Laparoscopic surgery for gastric tumor is considered a demanding procedure because of lymph node dissection and reconstruction. Billroth-I (B-I) reconstruction after laparoscopic distal gastrectomy is commonly performed extracorporeally because of the complexity of an intracorporeal procedure. Robotic surgery overcomes some limitations of laparoscopy, allowing to reproduce the basic maneuvers of open surgery. We describe a new technique to perform robotic B-I anastomosis.
