RESUMEN
BACKGROUND: Robotics has been proposed as a tool to improve laparoscopic Nissen fundoplication. However, a clear benefit of this technology for minimally invasive antireflux surgery has not been demonstrated. MATERIALS AND METHODS: A retrospective review of a prospective database was used to compare the intraoperative and postoperative outcome of 137 patients who underwent conventional laparoscopic fundoplication (CLF) and 45 patients who underwent laparoscopic robot-assisted fundoplication (LRF). Intraoperative outcome measures were: operative time, blood loss and complications. Length of hospital stay, functional results and patient satisfaction were used to compare postoperative outcome. RESULTS: Operative time was significantly shorter in the LRF group (65 min) compared to the CLF group (85 min) (p < 0.0001). The overall complication rate was comparable between the two techniques, even though a higher incidence of liver tears was encountered in the CLF group (p < 0.05). Hospital stay, symptom relief and patient satisfaction did not differ between the groups. CONCLUSION: Robotics improves surgeon dexterity and maneuverability during laparoscopic Nissen fundoplication, but this does not correspond to a better postoperative outcome. LRF should be used only for complex cases and training.

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. We have performed a retrospective analysis of 9 years with laparoscopic approach of the diverticular disease. The purpose of this study was to determine the feasibility, safety and benefits of laparoscopic approach. METHODS: From May 1994 to November 2002, 69 patients affected by non-complicated diverticular disease, were treated laparoscopically, at the Mininvasive Surgery Department of Spoleto. In the same period other 213 patients suffering from cancer of the colon-rectum were operated through laparoscopic surgery. A colosigmoid resection with mesenteric inferior artery preservation was performed in 46 cases (67%). RESULTS: We have performed only a laparoscopic colectomy technique (no hand-assisted procedures); the convertion rate was of 7.2%, the mean operative time was 145 min, no intraoperative complications were observed and finally the mean hospital stay was of 7.4 days (6-9). The postoperative complications were 1 case of infection of the umbilical scar and 1 case of pleural effusion with bronchopneumonia. CONCLUSIONS: Elective laparoscopic colectomy for diverticular disease is feasible, safe and gives very good results: minimum postoperative discomfort, rapid recovery, low mobility and postoperative stay, rapid return to normal activities. However, in some cases, this procedure can be extremely difficult because of previous inflammatory complications (adhesions, fistulas or stenosis), therefore, high surgical skills in laparoscopic-colic surgery are required.

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). This methods almost always replaces the surgical excisional biopsy and frozen intraoperative examination, still used but reserved for particular cases. PATIENTS AND METHODS: In our Department of General and Mininvasive Surgery, from December 1999 to September 2004, we carried out 214 biopsies, with the collaboration of the radiological Service, under echographic guidance using vacuum--assisted biopsy (Mammotome) with 11-Gauge needle. The results are examined and discussed here in this report with regard to diagnostic accuracy, quantity and quality of information, significant for subsequent surgical management. RESULTS: Of 214 biopsies carried out with Mammotome technique, 89.3% of the cases are clinically non palpable lesions, with a average diameter of 8 mm. The average age of patients was 57.6 years (range 31-88). There are 90 cases of positive malignant pathology (42%). In the atypical ductal iperplasia and radial scar cases (6%) surgical removal of lesion was carried out which confirmed the previous bioptic diagnosis in 100% of cases. The 19% of patients submitted to a Mammotome biopsy was subject previously to cytology with fine needle. Comparing the results of both methods the diagnostic reliability of Mammotome was significantly superior (p < 0.05) as also the amount of information obtained (histotype, invasivity, grading, estrogen receptor, etc.); discomfort linked to the procedure, valued as pain (VAS), resulted inferior to the discomfort of biopsy with fine needle. The only complication of Mammotome biopsy is represented by haematoma in the biopsy site (8% of cases). The number of false negatives was one case due to incorrect targeting. CONCLUSION: In the present situation, the choice of method is conditioned by the degree of radiological suspicion, taking into account the information obtained thereby, in order to ensure the appropriate surgise management. Mammotome biopsy of non palpable lesions of the breast, in our experience, is preferable if suspicion of malignancy is high. In this way a correct preoperative strategy can be prepared. Including the sentinel lymphnode method. Consequently a decision regarding the type of surgery can be taken (generally conservative), as well as making easier the intraoperative localisation of lesion by positioning the metallic clips during biopsy.

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. METHODS: A retrospective analysis of a series of 180 laparoscopic colon resections performed between 1994 and 2001 is presented. Surgical indications were: 46 cases of benign disorders and 134 colonic malignancy. The right hemicolectomy were 27 (15%): 2 benign and 25 malignant diseases. The technical aspects of completely laparoscopic right hemicolectomy is described in details. A completely mechanical intra-corporeal anastomosis is always performed. To remove the bowel specimen from the abdominal cavity it is put it in a large bag and pull it out of a 3-4 cm enlargement of a trocar-site (in the umbilical scar). RESULTS: Data of the 27 laparoscopic right hemicolectomy were analysed: there was 1 conversion to open surgery; no intra-operative complications were observed; the postoperative period was complicated by 1 anastomotic fistula. The median operative time was of 150 minutes. No case of port-site recurrence was observed. CONCLUSIONS: The laparoscopic colo-rectal surgery can reproduce in selected patients, the techniques performed in open surgery with minimally invasive treatment. It is possible to perform a completely laparoscopic right hemicolectomy after an adequate training in advanced laparoscopy, anyway there are many advantages: less postoperative pain, short-term postoperative ileus, earlier return to daily activity.

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%). The patients who had a confirmed diagnosis of acute appendicitis were grouped according to clinical-pathologic criteria into follicular, gangrenous and complicated appendicitisi; operating time, complications and length of hospital stay were compared among the three groups. VLA resulted superior to CLA in terms of diagnostic performance: among the patients with suspected acute appendicitis, VLA allowed to establish a different diagnosis in 41% as compared to 13% with CLA. In two cases (2.08%) VLA was turned into CLA. There were non differences between VLA and CLA in terms of surgical operating time and hospital stay. A significantly higher incidence of surgical complications, such as wound infections and pelvic abscesses, was observed in the CLA group as compared to VLA. The Authors conclude that VLA allows a complete exploration of the abdomen, a better localization of the appendix and an easier diagnosis of unexpected conditions or pathologic processes associated with the clinical appendicitis; further, VLA is gravated by fewer complications.

The Authors report two cases of ectopic gastric pancreas, one of them causing a massive upper gastrointestinal hemorrhage, representing an infrequent complication of the disease. A literature review on the subject was then performed, and the importance of a differential diagnosis of the ectopy versus gastric malignancies, with relevant prognostical and management implications was assessed.

From January 1989 to December 1992, in the Institute of Clinical Surgery of the University of Perugia, 102 patients were admitted for thoracic trauma. Two patients with an open thoracic trauma, both presenting multiple shot-wounds, underwent an explorative thoracotomy. One of them died on the operating-table from hemorrhage, while the other was saved by a wedge-resection. A 3rd explorative thoracotomy was successfully performed on a patient with internal thoracic trauma and severe hemothorax. Among the 100 patients with an internal thoracic trauma, mortality was 6%, but only one of the 6 deceased, had no lesions other than a fail chest. As a matter of fact 38 patients presented lesions in other parts of the body. Simple and complicated multiple costal fractures, found in 84 cases, were the most frequent lesions observed. Seventeen of the 38 patients with pneumothorax and/or pleural effusion had a chest tube applied. Three patients were operated for a diaphragmatic hernia with a positive outcome. Only 75 patients received medical treatment without surgery. Six of the patients with multiple costal fractures presented flail chest. One of them (mentioned above) died almost immediately after his admission and therefore received no more than the initial medical treatment. Four others, aged over 65, successfully underwent a costal osteosyntesis, while the 6th patient received medical therapy with a positive outcome. In the case of a critical flail chest with severe patho-physiological consequences, if the fractures are in technically favourable sites, the Authors believe it is better to immediately stabilize the thorax, since the operating trauma is minimum and in many cases the patient is already intubated and curarized.
