Intraoperative Ultrasound for Bowel Deep Infiltrating Endometriosis: A Preliminary Report.

The decision to perform either conservative surgery or segmental bowel resection for bowel deep infiltrating endometriosis (DIE) is made intraoperatively, after a preoperative assessment, based on the nodule's features. We introduce a technique to evaluate DIE bowel nodules using laparoscopic intraoperative ultrasound (US) during laparoscopic radical treatment of 9 cases of DIE invading the bowel. Once the bowel lesion was isolated, an intraoperative 12-4-MHz US transducer was placed on the surface of the nodules to study their US features and to gain measurements.

Laparoscopic Appendectomy Performed by junior SUrgeonS: impact of 3D visualization on surgical outcome. Randomized multicentre clinical trial. (LAPSUS TRIAL).

Background: The purpose of this study was to evaluate the effect of 3D visualization applied to laparoscopic appendectomy (LA) performed by young surgeons (YS). We considered both operative features and clinical outcomes, aiming to highlight the benefits that this technology could bring to novice surgeons and their laparoscopic training.

Methods: All the surgical procedures were performed by residents who had performed less than 20 appendectomies prior to the beginning of the study under the supervision of an expert surgeon.

Relationships between gastric development and anatomic bases of radical surgery for cancer.

The aim of this study was to determine with all possible accuracy the processes of embryologic development of the stomach and its lymphatics in order to confirm their supposed link with the modern anatomic bases of gastric cancer surgery. The knowledge of the anatomic behavior of the peritoneal folds and of the lymphatic drainage of the stomach is, in fact, considered the essential basis for the comprehension of the oncologic dissection of the stomach. The study was based on reconstruction of serial histologic sections of 9 human embryos and 8 human fetuses regarding the mesogastric area, as well as anatomic microdissection of 2 9-month fetuses.

The development of the suprarenal gland: surgical and anatomical considerations.

Background: Aim of this research is to study the situation and relationships of the adrenal gland in the first stage of development in order to give some contributes for the application of laparoscopic adrenalectomy; in the meantime we describe the series of the debate changes occurring in the constitution of the cortex and medulla.

Methods: Analysis of histologic slices of thoraco-abdominal and abdominal regions of human embryos and fetuses ranging from the fifth (12 mm CR) to the twentieth week (170 mm CR).

Results: At 12 mm CR an unique type of cells is present in the cortex; at 16 mm CR there are two different groups of cells.

Embryologic bases of extended radical resection in pancreatic cancer.

Objective: To analyze whether an embryologic "rationale" exists to the clinical and anatomicopathological data that suggest the execution of extended resections in patients with pancreatic cancer.

Methods: Reconstruction of serial histological sections of 18 human embryos and fetuses regarding the pancreatic region; anatomical microdissections of two 9-month fetuses.

Results: The ventral and dorsal pancreatic buds can be identified until the eighth week of development.
