According to the WHO about 300 million people in the world are affected by obesity with an increasing trend. The aim of the present study was to assess our preliminary results with sleeve gastrectomy. Over the period from June 2006 to March 2008, 25 laparoscopic sleeve gastrectomy were performed at our Department of Surgery for morbid obesity by the same surgeon. The operation consists in resection of approximately three quarters of the stomach with the creation of a long slender gastric tube, dividing the stomach vertically in two parts and removing all the left side with the greater curvature and gastric fundus. The mean age of the patients was 38 +/- 9 years, and the mean BMI 48 +/- 3. The mean operative time was 110 minutes, and the mean hospital stay 6 days. Mean intraoperative bleeding was negligible (20 cc). In our study we observed just one case of gastric leakage from the staple line, treated by surgical drainage and by placement of an endoscopic stent. There were no cases of bleeding of the resection margin and no long-term stenosis; there was no mortality. The mean follow-up was 18 months. BMI showed a mean reduction of about 17 points. During postoperative visits all the patients reported marked reduction of hunger sensation, together with a sense of early satiety. On the basis of these preliminary results we can consider laparoscopic sleeve gastrectomy as a safe, functional and definitive procedure that constitutes a valid alternative in bariatric surgery, though it is as yet not completely standardised and requires a longer follow-up.

The preoperative diagnosis of polycystic liver is easily obtainable by ultrasound, while computed tomography is more sensitive for making the differential diagnosis versus other hepatic lesions. This report describes a case of polycystic liver with mass-related symptoms. A laparoscopic fenestration of the larger and superficial cysts was performed. At a three-years follow-up neither postoperative complications nor recurrent episodes were observed. A number of studies have shown that the rates of cyst and symptom recurrence are 9% and 4.5%, respectively, and that the reduction of liver volume is 12.5%. in our opinion the choice of adequate treatment must be based on an accurate evaluation of the patient's clinical aspects and on tthe characteristics of cystic lesions, such as number, size and location. In conclusion, laparoscopic fenestration of liver cysts is a safe, effective procedure for obtaining excellent outcomes in terms of absence of recurrence, as well as being a more sparing approach.

The aim of the study was to consider all the factors associated with the development of postoperative dysphagia which, in its transitory form, can be present in as many as 40 to 70% of cases. From 1996 to 2007, 302 Nissen fundoplications were performed at our department of surgery. We divided this series into two groups, the first consisting of 149 cases (from March 1996 to March 2004) where short gastric vessels were not dissected (nl-VGB) and the second of 153 cases (from April 2004 to December 2007) where short gastric vessels were dissected (I-VGB).The incidence of postoperative dysphagia was distinctly lower in I-VGB than in nl-VGB (4.5% vs 19.5%). One month after operation, the incidence of postoperative dysphagia in I-VGB and nl-VGB was 12% and 1,5%, respectively, while 3 months after surgery the percentages were 2% and 0.5%. Exclusion of cases performed during the learning curve period yielded similar results. At postoperative examinations we noticed a substantial reduction in gastro-oesophageal reflux disease symptoms in both groups, with no significant difference between the two. L-VGB patients appeared clearly more satisfied after operation than nl-VGB patients (97% vs 88%), even if the results were similar after 3 months. Our experience confirms the good results obtained with Nissen fundoplication with a distinct, rapid reduction in postoperative dysphagia.

Background: Among bariatric operations, laparoscopic adjustable gastric banding (LAGB) has been the preferred one in Europe and Australia, and has become recently popular in the USA. Like every surgical procedure, however, it is not devoid of specific complications, like slippage, band erosion, outlet obstruction and port problems. Assuming that the absence of the pouch may avoid postoperative slippage, we introduced the technique of esophago-gastric placement, instead of the original gastric banding technique. A further technical variant, introduced in June 2002, consists of suturing the gastric fundus to the left hemidiaphragm, using two non-resorbable sutures and pledgets., Methods: Between January 1999 and July 2005, 400 LAGBs have been placed in 90 males and 310 females, with the technical variants above. Mean age was 42 (range 17-69 years), and mean BMI was 44.8 kg/m(2) (range 33-67)., Results: Mean hospital stay was 2.5 days (range 1-17). Mortality has been zero. Major complications included: 16 slippages (after a range of 6-45 months), 5 outlet obstructions (immediately after the operation), and one intragastric migration (after 2 years). Minor complications included 18 port problems. Since the introduction of gastric fundus fixation to the diaphragm in 2002, gastric slippage has decreased from 8% to 0.9%. BMI has decreased from 44.8 to 32 kg/m(2) at 60 months., Conclusions: The technique herein presented is effective and useful to prevent postoperative gastric slippage. It does not induce pseudo-achalasia, if strictly controlled. In fact, it is avoided by the patient due to the immediate appearance of dysphagia, in the case of wrong food ingestion. Long-term clinico-radiological follow-up confirms that the technique is safe and effective in motivated patients with good compliance and willing to undergo periodic studies.

Background: Laparoscopic gastric banding is effective in surgical treatment of morbid obesity, but has had the drawback of specific complications, like slippage and gastric erosion. To prevent such complications, modifications have been used, including high retrogastric positioning above the bursa omentalis, complete anterior fixation by gastro-gastric stitches over the band, and reduction of the pouch volume to < or = 15 ml. These technical variants may induce dysphagia., Methods: We adopted a different technique, consisting of placement of the band (9.75 cm BioEnterics Lap-Band) around the esophagus just above the cardia, to induce an amplification of the dysphagic mechanism. No fixation stitches were used., Results: From January 1999 to March 2001, 80 consecutive patients (16 males, 64 females, mean age 41 years, average BMI 45) were operated this way. All operations were completed laparoscopically. However, in 1 patient the procedure had to be interrupted for bleeding from a large fatty liver injury by the retractor. Complications included 2 cases of slippage: an early one after 24 h, requiring surgical removal, and a late one after 9 months, treated by laparoscopic repositioning. The third complication, a reactive esophageal stenosis, occurred in a transsexual male on estrogen treatment, that needed replacement with a wider Swedish band. Band adjustment was required in 28 patients, one time in 22 cases and twice in the other 6. Mean BMI decreased from 45 to 38 after 6 months, remaining at 37 after 24 months, while excess weight was reduced by 50% at 24 months., Conclusions: The technique has a re-educational function, in that patients are induced to chew thoroughly, to introduce small morsels of food and to prolong the mastication time, in order to avoid dysphagia. Laparoscopic adjustable esophagogastric banding gave no problem if well positioned, and promoted new alimentary habits through a dysphagic mechanisms, inducing significant excess weight loss.

Background and Purpose: Twenty years after the first report of laparoscopic appendectomy (LA), its role in the treatment of appendicitis is still under debate. We report herein a retrospective analysis of our cases of LA in the last 5 years, during which we adopted a policy of an almost uniform laparoscopic approach on a rather selected population composed mainly of women with acute or recurrent lower quadrant abdominal pain., Patients and Methods: Laparoscopic appendectomy was performed on 33 male and 98 female patients. The mean age at operation was 25.7+/-11.4 years (range 11-59 years). Acute appendicitis with localized or diffuse peritonitis was present in 34 cases. In the remaining 97 patients, the operation was performed for acute or recurring symptoms of lower quadrant abdominal pain., Results: There were no conversions to open surgery. The operating time was 45+/-17 minutes (range 30-110 minutes). The pathology examination of the removed appendices showed acute appendicitis in 34 cases and chronic inflammation in the remaining 97 patients. In one case, histology revealed a coexisting mucinous carcinoid that extended to the perivisceral fat, and a completion right hemicolectomy was performed. Complications were minor in most cases. Reoperation for deep abdominal abscess or hematoma was required in three cases. The mean hospital stay was 2.59+/-1.58 days (range 24 hours-11 days)., Conclusion: In our hands, LA has proven to be safe and effective. The laparoscopic operation has significant advantages in terms of lower invasiveness and better diagnostic capability. It is especially useful in women of child-bearing age, in whom it may be considered the procedure of choice.
