RESUMEN
From January 2011 to December 2015, 70 consecutive patients underwent either laparoscopic surgery (LS) or robotic surgery (RS) total mesorectal excision (TME) for malignancy. Data were prospectically recorded in a dedicated local database including ASA score, age, operative time, conversion rate, re-operation rate, early complications, length of stay, and pathological results. We enrolled 70 consecutive patients, 35 treated with LS (18 M, 17 F), 35 treated with RS (23 M, 12 F). Median total operative time was 225 min in LS group (IQR 194-255) and 252.5 min for RS group (IQR 214-300). Median first flatus time was 2 days for LS group (IQR 1-3) and 1 day for RS group (IQR 1-2). Stool discharge time (median) was 4 days for LS group (IQR 2-5) and 2 days for RS group (IQR 1-3). Length of stay (median) was 8 days in LS group (IQR 7-10) and 7 days in RS group (IQR 5-8). It was not found any statistically significant difference between the two groups when we analyzed the number nodes harvested the postoperative complications. The 30 day mortality was 0% in both two groups. The conversion rate for LS group was 23% (8/35 pts) and that for RS group was 0% (0/35). The RS may overcome technical limitations of LS. In our experience, it is a feasible and safe technique, it achieves better clinical outcomes due to the lower conversion rate compared to LS, although with higher costs.

Robotic-assisted resections prove beneficial in overcoming potential limitation of laparoscopy, but clear evidences on patient's benefits are still lacking. We report our experience on 100 consecutive patients who underwent right colectomy with either robotic or laparoscopic approaches. Data were prospectively collected on a dedicated database (ASA score, age, operative time, conversion rate, re-operation rate, early complications, length of stay, and pathological results). Median total operative time was 160 min in LS group (IQR = 140-180) and 204 min for RS group (IQR = 180-230). Median time to first flatus was 2.5 days for LS group (IQR = 2 - 3) and 2 days for RS group (IQR = 1-2). Length of stay (median) was 8 days in LS group (IQR = 6-10) and 5 days in RS group (IQR = 5-7). No statistically significant difference was found between the 2 groups when the number of harvested nodes, the anastomotic leakage and the postoperative bleeding were analyzed. The 30-day mortality was 0% in LS and RS groups. Conversion rate for LS group was 14% (7/50 pts) and for RS group was 0% (0/50). Minimally invasive surgery is a feasible and safe technique. The RS may overcome some technical limitations of laparoscopic surgery and it achieves the same oncological results compared to LS but with higher costs. The lower conversion rate allows to expect better clinical outcomes and lower complication rate.

Through this single-center consecutive prospective study, we evaluated the results of a combined approach for L5-S1 isthmic spondylolisthesis, using a polyetheretherketone (PEEK) interbody lordotic cage during anterior approach and pedicle screw-based posterior fixation. Between 2010 and 2014, 27 adult patients were treated for L5-S1 isthmic spondylolisthesis (high and low grades) by a combined approach with a minimum follow-up of one year. Clinical outcome was assessed before surgical treatment and at four months and one year after surgery by: VAS, Oswestry Index (ODI) and Rolland-Morris scores. Two observers evaluated the following radiological parameters: pelvic incidence, pelvic tilt, lumbar lordosis, segmental lordosis L5-S1, anterior and posterior disc height, spinal vertical axis (SVA), SVA/sacro-femoral distance (SFD) ratio. Fusion was evaluated on the CT scan at one-year follow-up. Blood loss, surgery time and complications were also collected. The mean age was 47.7 years (±16.9). The VAS, ODI and Rolland-Morris scores were significantly improved postoperatively, decreased from 7.5 (±1.45); 48 (±19.25); 15.3 (±4.67) before the surgery to 3.8 (±2.55); 28.7 (±19.58) and 7.76 (±7.21) respectively at one year after the surgery (P=0.05). The mean follow-up was 3.3 years. Mean surgery time was 193.7min (±37). Fusion was obtained in 100% of cases. Segmental lordosis L5-S1, pelvic tilt, slippage, anterior and posterior L5-S1 disc height were significantly improved postoperatively, they passed from 20.1; 22.6; 35.3%; 26.4%; 17.9% to 29.5; 20.6; 20.3%; 64.4%; 36.3% respectively. Combined surgical procedure meets the required goals of surgery in the treatment of adults L5-S1 isthmic spondylolisthesis.

Hernia repair is the most common surgical procedure in general surgery in Italy and in the Lombardy region. In the last decade, the use of mesh, the concept of a tension-free technique, and the postoperative rate of recurrences after Bassini or Shouldice operations have completely changed the surgical approach to hernia repair. For this reason, we sent a questionnaire to 148 surgical departments in the Lombardy region to investigate about total hernia operations performed in 2000 in Lombardy, the surgical approach, the surgical techniques used, the type of anesthesia and the hospital stay. One hundred five out of 148 surgical departments returned the questionnaire, and we collected information on a total of 16,935 surgical operations for hernia: 16,494 were performed using tension-free techniques. The inguinal anterior approach is the one of choice for primary and recurrent inguinal hernia, whereas the open preperitoneal and laparoscopic approaches are limited to bilateral and recurrent hernias. The majority of cases were treated under locoregional anesthesia and with a hospital stay of two nights.

Traumatic diaphragmatic rupture is not an uncommon problem, particularly in the last few years because of the increasing number of road accidents, improved diagnostic techniques and resuscitation techniques after serious traumas. In a certain number of cases, post-traumatic diaphragmatic hernias may become clinically manifest only months or years after thoracic or abdominal trauma and are still a challenge to surgeons because of the vague clinical symptoms and the diagnostic difficulties involved. The Authors report a case of acute colon occlusion due to diaphragmatic hernia 24 months after thoraco-abdominal trauma. None of the radiological or endoscopic examinations demonstrated the presence of diaphragmatic hernia. Laparoscopy showed a diaphragmatic rupture with incarceration of the left colonic segment. The laparoscopic procedure was converted for technical reasons and the diaphragmatic defect was closed with a primary suture.

The true diverticula of the small bowell are a very rare observation in clinical practice; they have a malformative origin and, occasionally, are acquired, contrary to what observed in the colon, where they are frequently an acquired pathology. They can involve the small bowel as a single lesion (Meckel's diverticulum), or as a segmentary disease (duodenal diverticula), or as a diffused diverticulosis. Generally they are asymptomatic and rarely they produce a true pathology. The symptomatic disease is primarily found in pediatric age and it requires a surgical procedure. This makes even more rare the diverticular pathology in the adult. The authors report 1 case of intestinal occlusion due to ileoileo-colic invagination arising from a Meckel's diverticulum and 1 case of intestinal occlusion in presence of a severe and acute diffuse diverticulosis of the small bowell, both in adult patients.

One-hundred-eighty patients underwent emergency minimally invasive procedures (laparo and thoracoscopy) in the last two years. In twelve postoperative drawbacks another surgical procedure was performed. Laparoscopic or thoracoscopic exploration was undertaken in 8 cases while open surgery was done in 4. Complications and surgical overtiming rate was higher after endoscopic than open surgery. This approach allows us to correct very few and selected disease when a skilled surgical team is available especially during reoperations.

Regarding a case of rectal endometriosis, presenting with cyclic menstrual rectal bleeding, the authors discuss the clinical and treatment aspects of such a rare pathology. History was sufficient to indicate the diagnosis which was confirmed by the histological examination of the excised rectal tract. These observations underline the diagnostic difficulty; the surgical approach is the treatment of choice when medical treatment gives no success.

In the last three years (1992-1995) 130 stab (114) and gunshot (16) wounds were observed at and admitted to the Emergency Surgical Department of Fatebenefratelli Hospital of Milan. We observed a high incidence of non-EEC patients (62%). Imaging devices (US and CT scan) and surgical minimally invasive procedures have reduced open surgery rate with a remarkable reduction in drawbacks and mortality.

In the last two years 203 patients underwent minimally invasive surgery for thoracic and abdominal emergencies. Thoracic and abdominal surgical exploration was performed for acute disease and blunt traumas except gunshots. Early open surgery was performed to avoid intraoperative problems and to minimize anesthesiological overtime with a minimally invasive/open surgery ratio of 23% (46 patients). Bleeding, adhesions and visceral damage proved the most frequent causes of open surgery conversion. Nine patients underwent laparotomy for postoperative complications while in 4 patients another minimally invasive procedure was performed. Five patients showed spontaneous recovery of postoperative complications. Minimally invasive procedures are useful as diagnostic and therapeutic procedure in many acute diseases with a shorter hospitalization than open surgery.

Our study was carried out to determine the prevalence of chronic fatigue syndrome (CFS) within a selected population of patients suffering from persistent fatigue. We studied subjects with recurrent or persistent fatigue lasting 6 months and fulfilling at least four minor Center for Disease Control (CDC) criteria for the diagnosis of CFS. Evaluation included both clinical examination and laboratory testing. All subjects filled out a questionnaire specifically designed to gain information about the length and severity of symptoms, and patients with a previously diagnosed illness associated with fatigue were excluded. The study was carried out at the Fatigue Clinic of an internal medicine unit (Clinica Medica I) of the University of Rome "La Sapienza". Sixty-three subjects, residents of the Lazio region (central Italy), completed the diagnostic assessment. Alternative diagnoses were established in 37 (59%) of the 63 patients. A diagnosis of CFS based on the CDC criteria was established in only 6 cases. In 2 subjects, CFS had appeared following infectious mononucleosis, and no definitive diagnosis could be formulated for 18 patients. In Italy, CFS seems to be an infrequent cause of severe and persistent fatigue in a selected population. Numerous morbid conditions may be responsible for a clinical picture closely resembling CFS. We recommend that patients suffering from fatigue be thoroughly evaluated.

The aim of the study was the investigation of the ability of L-acetylcarnitine (Acn; 1.5 g daily oral route for 1 month) to enhance some performances requiring a high level of attention and reflex velocity. The sample includes 17 healthy subjects, 8 males and 9 females, 22 to 27 years old; 10 of the subjects practice sports at agonistic level, while 7 have a sedentary life style. Reflexes have been measured, baseline and after 17 and 30 days of Acn administration, through a purposely constructed reflex-meter able to determine the latency (csec) of the reaction to an auditory stimulus. The ability as well as the time of learning was determined, before and after treatment, as the time and the number of errors to get out of the maze of a videogame (the test was also carried out by an untreated control group). Acn seems to induce an enhancement of reflex velocity, with complete annulment of the difference between the dominant and the opposite hand, as well as a significant reduction (3 to 4 times superior to controls) of both the errors and the time with the maze test.

CEA and TPA were studied in sera and in histologic specimens of 200 patients with benign (77) or malignant (123) breast pathology. The frequency and expression of the two markers was different in benign and in cancer tissues. Histologic positivity and high levels of circulating markers were observed more frequently in cancer patients than in patients with benign disease. Tissue positivity for the two tumor markers did not always correlate with elevated levels of circulating markers. Positive CEA and TPA incidence was higher in tissue samples than in serum samples. In the breast cancer group, among 33 patients with histologic positivity for CEA, only 5 cases had circulating CEA levels higher than 5 ng/ml; among 91 patients with histologic positivity for TPA, only 45 cases showed circulating levels for TPA higher than 95 U/l. These findings confirm that tumor size, secretory characteristics and vascular supply are factors affecting the achievement of high circulating marker levels. Combined marker measurement in serum and tissues can provide more information about the presence of a given tumor marker. A limited evaluation of the prognostic meaning of the study of combined CEA and TPA in sera and in tissues was carried out during the follow-up of 60 evaluable patients. Only 5 patients had cancer relapses in the first 12 months from surgery; in 2 of 5 patients TPA was positive initially and at the time of recurrence, in serum as well as in tissues. Circulating CEA gave negative findings in all relapsed patients; 2 of them showed weak positivity only in the histologic staining at the time of presentation.

For many years pathologists have argued about the definition and the biologic reasons of what is "early", "minimal" and "occult" breast cancer. Whether these terms really identify entities which today can be meaningful to clinicians and whether the prognostic significance of breast cancer measuring 1 cm or less in diameter should have implications in the treatment decision making will form the subject of this review.

Patients with malignant and benign colon disease (59 colon cancer and 96 polyps) were studied by means of tissue polypeptide antigen (TPA) and carcinoembryonic antigen (CEA) tests. The evaluation of the circulating levels of the markers showed that the overall sensitivity for the TPA test was 57.6% and for the CEA test was 55.9%. Their specificities were 89.5% and 94.7%, respectively. The analysis of results indicated no considerable difference between CEA and TPA in detecting individuals with malignant diseases. There was only a slight difference in Dukes stages: in stages A and B, TPA sensitivity was higher than CEA sensitivity. On the contrary, in the group of patients with polyps, more false-positive results were obtained with the TPA test than with the CEA test. Immunohistochemical studies on the small group of patients (12 colon cancers) allowed us to evaluate the relationship between the staining positivity for the anti-TPA and anti-CEA antibodies and the circulating levels of the markers. The staining in some cases was not correlated either with the stage of cancer or the circulating TPA or CEA levels. This fact further shows the need to investigate the mechanism that determines the blood levels of many tumor markers. All the specimens examined were positive for TPA and CEA staining, but they were composed of varying proportion of positive and negative tumor cells. The degree of positivity was frequently variable not only between the specimens but also within the same specimen.
