Robot-assisted laparoscopic total and partial gastric resection with D2 lymph node dissection for adenocarcinoma.

Background: Lymph node dissection and esophageal anastomosis, considered the more demanding steps of laparoscopic gastrectomy for gastric adenocarcinoma, can be performed with the use of a remote-controlled robot.

Methods: Thirteen patients with a histologically proved gastric cancer (six stage I, six stage II, and one stage III) were enrolled in a prospective study to assess feasibility and safety of the Da Vinci surgical system in total and partial gastrectomy with extended lymph node dissection. Outcome measures were conversion rate, intra- and postoperative morbidity and mortality, operative time, blood loss, number of lymph nodes harvested, and macroscopic and microscopic evaluation of resection margins.

[Laparoscopic repair of incisional and umbilical hernias. Our experience].

Background: Incisional hernia is a frequent complication of abdominal surgery (2-20% of all cases). Recurrence rate after simple repair without mesh is very high. The use of prosthetic materials has reduced the recurrences.

A modified umbilical incision for specimen extraction after laparoscopic abdominal surgery.

Background: One advantage of laparoscopic surgery over open surgery is the absence of laparotomic incisions. This advantage is reduced when an auxiliary incision is performed to remove surgical specimens larger than the trocar.

Methods: A special incision was performed at umbilical trocar level that enabled removal of a large surgical specimen as in right hemicolectomy (colic), gastric resection, and splenic surgery.

Comparing fibrin sealant with staples for mesh fixation in laparoscopic transabdominal hernia repair: a case control-study.

Background: Laparoscopic hernia repair is not as popular as cholecystectomy. We have performed more than 3,000 laparoscopic herniorrhaphies using the trans-abdominal (TAPP) technique. To prevent recurrences we fix the polypropylene mesh with staples.

The biliopancreatic diversion. A comparison of laparoscopic and laparotomic techniques.

Aim: Morbid obesity has increased its frequency in the last 20 years in association with the increase of a country's richness. Bariatric surgery has developed a role which is becoming more and more important. The aim of this study, after 10 years of experience with the biliopancreatic diversion, is to compare the laparoscopic versus open technique

Methods: From March 1993 to December 2004, 150 patients were operated by biliopancreatic diversion.

[Laparoscopic colon-sigmoid resection with mesenteric artery preservation for diverticular disease].

Aim: About 2/3 of the Western population over the age of 80 years are affected by colic diverticulosis; 25% will develop diverticular disease with or without complications: fistula, obstruction, pericolic abscess, free perforation or hemorrhage. Laparoscopic approach for benign diseases of the colon such as diverticulosis, Chrohn's disease, etc. is unanimously considered as a very effective procedure.

[Non palpable lesions of the breast: the Mammotome-biopsy in the preoperative management of breast cancer].

Background: Breast tumour takes first place for frequency in women in Western Countries and is in constant increase. The diagnosis of the so-called non palpable lesions is increased remarkably above all due to the diffusion of mammographic screening and to a greater awareness of the problem. Furthermore it is helped by an important development of mininvasive diagnostic methods: the traditonal cytology with fine needle is supported by various trans-skin bioptic procedures (micro-histological examination).

[Neoplastic residues in the trocar tract in oncologic laparoscopic surgery].

Aim: The laparoscopic approach to malignant diseases runs up against both old and new problems: respect for the principles of radicality, operating times, the postoperative course and surgical complications, long-term oncological results in terms of survival and recurrence of the disease. One of the problems which has received most attention regards the onset of a metastasis on a trocar scar or a mini-laparotomy recurrence. Trocar site tumor recurrences have been described in the literature following laparoscopic surgery in almost all abdominal malignant pathologies (colorectal, gynaecological, pancreatic, etc.

[Laparoscopic right hemicolectomy with intracorporeal anastomosis. Technical aspects and personal experience].

Background: Laparoscopic colo-rectal surgery has gained wide acceptance as a treatment in a variety of benign and malignant diseases. The reproducibility and safety of all the principal colo-rectal procedures has been demonstrated, but some indications are still controversial. A great part of surgeons perform right hemicolectomy by laparo-assisted technique and consider it more difficult than left hemicolectomy.

[Laparoscopic approach versus laparotomy for suspected acute appendicitis].

Acute appendicitis is one of the most common surgical disease but, in spite of the progression diagnostic imaging, a definite diagnosis is frequently difficult and often is based in essentially clinical grounds. The Authors retrospectively analyze the results of conventional laparotomic appendectomy (CLA) and videolaparascopic appendectomy (VLA) as performed by two teams of their Department of Surgery. Between January 2000 and November 2001, 156 patients, age ranging from 3 to 67 yrs, underwent surgery because suspected acute appendicitis; 96 patients underwent VLA and 60 patients underwent CLA; a diagnosis of acute appendicitis was confirmed in 142 cases (91%).

[Varicocele. Ligation of the internal spermatic vein using laparoscopic approach].

It is now unquestionable that varicocele represents one of the main causes of male infertility, and thus requires appropriate surgical treatment. Inguinal and retroperitoneal methods have for some time been the most widely used. However, a significant postoperative morbidity and relatively long convalescence have prompted the search for alternative surgical techniques, such as percutaneous sclero-embolisation and microsurgery.
