[Our experience on the treatment of epigastric hernia]. / Nostra esperienza sul trattamento dell'ernia epigastrica.

The epigastric hernia represents a rare surgical affection, sometimes insidious, whose pathogenesis has been discussed for a long time, revealing, in the course of the years, multiple predisposing and responsible factors of its appearance. From our experience and the data reported in the literature, it is clear that a standard surgery does not exist for this pathology, and it is often necessary to perform preliminary uncommon diagnostic exams. Our retrospective study consists in the analysis of the surgical treatments executed, from 2003 to 2006, on 37 patients suffered from epigastric hernia, for everyone of which, on the basis of the clinical features, of the preoperative diagnostic results and of the characteristics of the hernia defect, it has been encouraged a personalized surgical procedure,obtaining therefore, for the same pathology, different treatment protocols (open or laparoscopic procedures, ordinary hospital stay or day-surgery, prosthetic or not surgical repair).

Obese teenagers treated by Lap-Band System: the Italian experience.

BACKGROUND: Little is known about obesity surgery in young and adolescent patients. The aim of this study is to evaluate results of laparoscopic adjustable gastric banding in obese teenagers. METHODS: Patients < or = 19 years old selected from the database of the Italian Collaborative Study Group for Lap-Band were analyzed according to mortality, comorbidities, laparotomic conversion, intra- and postoperative complications, body mass index (BMI), and % excess weight loss (EWL) at different times of follow-up. Data were expressed as mean +/- SD. RESULTS: Fifty-eight (1.5%) of 3813 patients who underwent operation with the Lap-Band System were < or = 19 years old: 47F/11M; mean age, 17.96 +/- 0.99 years (range, 15-19); mean BMI, 46.1 +/- 6.31 Kg/m2 (range, 34.9 - 69.25); mean % excess weight, 86.4 +/- 27.1 (range, 34 - 226.53). Sixteen (27.5%) of the 58 patients were superobese (BMI > or = 50). In 27/58 (46.5%) patients, 1 or more comorbidities were diagnosed. Mortality was absent. Laparotomic conversion was necessary in 1 patient with gastric perforation on the anterior wall. Overall postoperative complications occurred in 6/58 (10.3%). The band was removed in 6/58 (10.3%) patients for gastric erosion (3 patients), psychologic, intolerance (2 patients), and in the remaining patient was converted 2 years after surgery (BMI 31) to gastric bypass or gastric pouch dilatation. Patient follow-up at 1, 3, 5, and 7 years was 48/52 (92.3%), 37/42 (88.1%), 25/33 (75.7%), and 10/10, respectively. At these times, mean BMI was 35.9 +/- 8.4, 37.8 +/- 11.27, 34.9 +/- 12.2, and 29.7 +/- 5.2 Kg/m2. Mean %EWL at the same time was 45.6 +/- 29.6, 39.7 +/- 29.8, 43.7 +/- 38.1, and 55.6 +/- 29.2. Five/25 (20%) patients had < or = 25% EWL at 5 years follow-up, while none of the 10 patients subject to follow-up at 7 years had < or = 25% EWL. CONCLUSIONS: Lap-Band System is an interesting option for teenagers suffering obesity and its related comorbidities, which deserves further investigation.

Insulin/insulin-like growth factor I hybrid receptors overexpression is not an early defect in insulin-resistant subjects.

Hybrid receptors (HRs), insulin receptor (IR)/insulin-like growth factor I receptor (IGF-I-R) heterodimers have been reported increased in skeletal muscle of obese and type 2 diabetic patients and to contribute to the patient insulin resistance. To investigate whether or not the increased expression of hybrid receptors is an early defect (probably genetic) of insulin resistance, we measured by specific enzyme-linked immunosorbent assays both IR, IGF-I-R, and HR content in skeletal muscle of healthy nonobese, nondiabetic subjects either insulin sensitive or insulin resistant, and also in patients with moderate obesity. IR content was significantly reduced in insulin-resistant subjects both nonobese and obese, compared with insulin-sensitive subjects (2.32+/-0.26, 2.36+/-0.18, and 3.45+/-0.42 ng/mg protein, respectively, P = 0.002). In contrast, IGF-I-R content was similar in the three groups. Muscle HR content was not different in insulin-sensitive vs. insulin-resistant subjects (both nonobese and obese) (4.90+/-0.46, 4.69+/-0.29, and 4.91+/-0.25 ng/mg protein, respectively, P = not significant). These studies indicate that, in insulin-resistant subjects without diabetes or severe obesity, muscle IR content but not IGF-I-R or HR content is reduced. They do not suggest, therefore, a primary (genetic) role of increased HR as a cause of IR decrease and insulin resistance.

Italian Group for Lap-Band System: results of multicenter study on patients with BMI < or =35 kg/m2.

BACKGROUND: The Lap-Band System is the most common bariatric operation world-wide. Current selection criteria do not include patients with BMI < or = 35. We report the Italian multicentre experience with BMI < or = 35 kg/m(2) over the last 5 years. PATIENTS AND METHODS: Data were obtained from 27 centres involved in the Italian Collaborative Study Group for Lap-Band System. Detailed information was collected on a specially created electronic data sheet (MS Access 2000) on patients operated in Italy since January 1996. Items regarding patients with BMI < or = 35 were selected. Data were expressed as mean +/- SD except as otherwise indicated. RESULTS: 225 (6.8%) out of 3,319 Lap-Band patients were recruited from the data-base. 15 patients, previously submitted to another bariatric procedure (BIB =14; VBG= 1) were excluded. 210 patients were eligible for study (34M/176F, mean age 38.19+/-11.8, range 17-66 years, mean BMI 33.9+/-1.1, range 25.1-35 kg/m(2), mean excess weight 29.5+/-7.1, range 8-41). 199 comorbidities were diagnosed preoperatively in 55/210 patients (26.2%). 1 patient (0.4%) (35 F) died 20 months postoperatively from sepsis following perforation of dilated gastric pouch. There were no conversions to laparotomy. Postoperative complications presented in 17/210 patients (8.1%). Follow-up was obtained at 6, 12, 24, 36, 48 and 60 months. At these time periods, mean BMI was 31.1+/-2.15, 29.7+/-2.19, 28.7+/-3.8, 26.7+/-4.3, 27.9+/-3.2, and 28.2+/-0.9 kg/m(2) respectively. Co-morbidities completely resolved 1 year postoperatively in 49/55 patients (89.1%). At 60 months follow-up, only 1 patient (0.4%) has a BMI >30. CONCLUSIONS: Although surgical indications for BMI < or = 35 remain questionable, the Lap-Band in this study demonstrated that all but 1 patient achieved normal weight, and most lost their co-morbidities with a very low mortality rate.

Laparoscopic Italian experience with the Lap-Band.

BACKGROUND: An increasing number of surgeons with different levels of experience with laparoscopic surgery and open obesity surgery have started to perform laparoscopic implantation of the Lap-Band. METHODS: An electronic patient data sheet was created and was mailed and e-mailed to all surgeons performing laparoscopic adjustable silicone gastric banding (LASGB) in Italy. Patients were recruited since January 1996. Data on 1,265 Lap-Band System operated patients (258 M/1,007 F; mean BMI 44.1, range 27.0-78.1; mean age 38, range 17-74 years) were collected from 23 surgeons performing this operation. RESULTS: Intra-operative mortality was absent. Post-operative mortality was 0.55% (7 patients) for causes not specifically related to LASGB implantation. The laparotomic conversion rate was 1.7% (22 patients). LASGB related complications occurred in 143 patients (11.3%). Pouch dilatation was diagnosed in 65 (5.2%), and 28 (2.2%) of these underwent re-operation. Band erosion was observed in 24 patients (1.9%). Port or connecting tube-port complications occurred in 54 patients (4.2%), 12 of whom required revision under general anesthesia. Follow-up was obtained at 6, 12, 18, 24, 36 and 48 months, and mean BMI was respectively 38.4, 35.1, 33.1, 30.2, 32.1 and 31.5. The percentage of patients observed at each follow-up was > 60%. There was no intra-operative mortality and no complication-related mortality, with acceptable weight loss. CONCLUSION: The LASGB operation is safe and effective, and deserves wider use for treatment of morbid obesity.

Results of the Italian multicenter study on 239 super-obese patients treated by adjustable gastric banding.

BACKGROUND: Laparoscopic adjustable gastric banding (LAGB) is the most common bariatric operation. This study is a retrospective analysis of the multicenter Italian experience in patients with BMI > 50 over the last 4 years. METHODS: An electronic data sheet made for LAGB-operated patients since January 1996, was mailed and e-mailed to all surgeons involved in this kind of procedure in Italy. Items regarding patients with BMI > 50 were selected. Analysis used Fisher's exact test and logarithmic regression analysis (P < 0.05 significant). Data were expressed as mean +/- SD. RESULTS: 239 patients (13.3%), out of 1,797 Lap-Band operated patients entered the study (179F / 60M), with mean age 37.6 +/- 11.3 years (19-69) and mean BMI 54.6 +/- 4.8 (50.1-83.6). Laparotomic conversion rate was 5.4% (44/239). Postoperative complications occurred in 24 / 239 patients (9.0%). Follow-up was obtained in 218 / 218, 198 / 198, 121 /147, 75 / 93, 30 / 38 LAGB patients at 6,12, 24, 36, and 48 months respectively. At these time periods, mean BMI was 46.7, 43.9, 42.2, 41.9, and 39.3 kg/m2. At the same intervals, mean %EWL was 24.1, 34.1, 38.8, 38.9, and 52.9%. The number of patients with < 25% EWL at 12, 24, 36, and 48 months follow-up were 34, 10, 4, and 0. Serious co-morbidities (189 in 124 of 239, 57%) had completely resolved 1 year postoperatively in 74 / 124 of the patients (59.6%). CONCLUSION: Although super-obese patients following the LAGB remain obese with BMI > 35, in the short-term most lose their co-morbidities, with a very low morbidity and mortality rate.

Lap Band adjustable gastric banding system: the Italian experience with 1863 patients operated on 6 years.

BACKGROUND: The Lap Band system procedure is currently the most common bariatric surgical procedure worldwide. This is an interim report of the experience of the 27 Italian centers participating in the national collaborative study group for Lap Band (GILB). METHODS: An electronic database was specifically created. It was mailed and e-mailed to all of the surgeons now performing the laparoscopic gastric banding operation in Italy. RESULTS: Beginning in January 1996, 1893 patients were recruited for the study. There were 1534 women and 359 men with a mean body mass index (BMI) of (range 30.4-83.6) and a mean age of 37.8 +/- 10.9 years (range; 17-74). The mortality rate has been 0.53% (n = 10), mainly due to cardiovascular complications (myocardial infarction, pulmonary embolism). The laparotomic conversion rate has been 3.1% (59/1893) and was higher in superobese patients (BMI>50) than in to morbidly obese patients (BMI <50) (p <0.05). Postoperative complications occurred in 193 patients (10.2%), including tube port failure (n = 79; 40.9%), gastric pouch dilation (GPD) (n = 93; 48.9%), and gastric erosion (n = 21, 10.8%). Most GPD (65.5%) occurred during the first 50 patients treated at each center. The incidence of GPD decreased as the surgeons acquired more experience. Surgery for complications was often performed by laparoscopic access, rarely via laparotomy. No death was recorded as a consequence of surgery to treat complications. Weight loss has been evaluated at the following intervals: 6, 12, 24, 36, 48, 60, and 72 months, with BMI 37.9, 33.7, 34.8, 34.1, 32.7, 34.8, and 32. CONCLUSIONS: The Lap Band system procedure has a very low mortality rate and a low morbidity rate and it yields satisfactory weight loss. Surgery for complications can be performed safely via laparoscopic access.

The Italian Group for LAP-BAND: predictive value of initial body mass index for weight loss after 5 years of follow-up.

BACKGROUND: Laparoscopic of the LAP-BAND System placement stage of obesity is a safe operation, but its indication in terms of stage of obesity is controversial. The aim of this study was to evaluate the 5 years stage of obesity results for weight loss in patients with varying preoperative ranges of body mass index (BMI). METHODS: Data were obtained from the Italian Collaborative Study Group for LAP-BAND System (GILB) registry. Detailed information was collected on a specifically created database (MS Access 2000) for patients operated on in Italy from January 1996 to 2003. Patients operated on between January 1996 and December 1997 were allocated to four groups according to preoperative BMI range: 30-39.9 kg/m(2) (group A), 40-49.9 kg/m(2) (group B), 50-59.9 kg/m(2) (group C), and =60 kg/m(2) (group D) percent estimated weight loss respectively. Postoperative complications, mortality, BMI, BMI loss, and (%EWL) were considered in each group. Data are expressed as mean +/- SD, except as otherwise indicated. Statistical analysis was done by means of Fisher's exact test, and p < 0.05 was considered significant. RESULTS: After 5 years from LAP-BAND System surgery, 573 of 3,562 patients were eligible for the study. One hundred fifty-five of 573 (27.0%) were lost to follow-up, 24 of 418 (5.7%) underwent band removal due to complications (gastric pouch dilation, band erosion), eight of 418 (1.9%) were converted to other bariatric procedures, five of 418 (1.2%) died of causes not related to the operation or the band, and 381 of 573 (66.5%) were available for follow-up. Based on 96, 214, 64, and seven patients their preoperative BMI, Were allocated to groups A, B, C, and D, respectively. At time of follow-up mean BMI was 27.5 +/- 5.2 in group A, 31.6 +/- 4.7 in group B, 37.6 +/- 17.3 in group C, and 41.4 +/- 6.9 kg/m(2) in group D. Mean BMI loss was 9.8 +/- 5.4, 12.9 +/- 5.2, 15.8 +/- 8.1, and 23.2 +/- 4.9 kg/m(2), respectively, in groups A, B, C, and D. Mean %EWL at the same time was 54.6 +/- 32.3 in group A, 54.1 +/- 17.2 in group B, 51.6 +/- 35 in group C, and 59.l +/- 17.1 in group D. CONCLUSION: Initial BMI in this series did not correlate with %EWL 5 years after the operation. In fact %EWL was almost the same in each group, independent of preoperative weight. Initial BMI was an accurate indicator of the results obtained 5 years after LAP-BAND in group C (50-59.9 kg/m(2)) and D (=60 kg/m(2)) patients, who remained morbidly obese despite their %EWL.

[Popliteal artery entrapment syndrome]. / La sindrome da intrappolamento dell'arteria poplitea.

Trapped popliteal artery syndrome is relatively uncommon: the literature reports some 60 cases. The clinical picture is linked to compression of the popliteal artery by the gastrocnemius as it contracts, thus distorting the arterial route. The result is an interruption in the blood flow distally to the area involved due to stenosis of the blood vessel that is at first functional but becomes organic.

Long-term results after a low anterior resection with mucosectomy and colo-anal sleeve anastomosis for a diffuse cavernous haemangioma of the rectum.

Diffuse cavernous hemangioma of the rectum is an unusual lesion. We reporting the case of an 18-year-old man with a rectal cavernous hemangioma in whom recurrent rectal bleeding and marked anemia were thought to be caused by his co-existing internal hemorrhoids. This resulted in a 2-year delay in reaching the correct diagnosis. Digital rectal examination revealed a walnut-sized, wide-based, elastic, soft mass 3 cm proximal to the anal verge. Colonoscopy revealed a bluish, submucosal lesion with superficial capillary dilatation at the same site. Arteriography demonstrated vascular tumours in the territory of the right hypogastric artery and the superior rectal artery. In 1972, Parks and co-workers described resection and colo-anal sleeve anastomosis as an alternative operation in the treatment of this rare malformation. We will describe the clinical presentation, diagnosis, and long-term results in a patient with this condition managed with this surgical technique. The patient has done well without any recurrence of rectal bleeding for over 10 years since his operation. Resection with a colo-anal sleeve anastomosis offers major advantages such as a lower risk of intraoperative bleeding, no risk of damaging the pelvic nerves, sparing of continence and avoidance of a permanent colostomy. It should therefore be considered the treatment of choice for this uncommon condition.

Malignant schwannoma of the rectum: a clinical and pathological contribution.

Schwannomas of the rectum are uncommon and incompletely characterized tumours, and only a limited number of cases have been reported. On the basis of a case of rectal schwannoma and a review of the literature on this rare condition, we stress the importance of the clinical features, diagnostic difficulties and surgical indications for the various therapeutic approaches. The basis for radical operation, due to the tendency of such tumours to recur locally and the real possibility of malignant degeneration, is discussed. We also emphasize the difficulty of making a benign diagnosis with histological certainty.

[Systemic neoadjuvant chemotherapy in locally advanced gastric carcinoma: phase II study with 5-fluorouracil, epirubicin and etoposide]. / Chemioterapia neoadiuvante sistemica nel carcinoma gastrico localmente avanzato: studio in fase II con 5-fluorouracile, epirubicina ed etoposide.

Locally advanced gastric adenocarcinomas have a poor prognosis, particularly when the tumours are bulky, located in the cardia or when they present local/regional lymph node involvement. Neoadjuvant chemotherapy for locally advanced gastric cancer is an experimental treatment strategy that may increase resectability and improve survival in patients suffering from an almost uniformly fatal neoplasm. At our institution 11 patients younger than 70 years of age in good physical and mental condition with non-resectable adenocarcinomas of the stomach as determined by endoscopy, computed tomography scans and pathology examinations, were treated with combination chemotherapy [5-fluorouracil (375 mg/m2 i.v. for 5 days, epirubicin (60 mg/m2 i.v. on day 1), etoposide 80 mg/m2 on days 1, 2 and 3, leucovorin 100 mg/m2 for 5 days] every 4 weeks as neoadjuvant chemotherapy. The response to chemotherapy was evaluated after three courses. After three courses, we had one complete response, 8 partial responses or stable disease, and no response in two cases. One patient was still alive 36 months postoperatively. These preliminary results suggest that this protocol is an effective form of neoadjuvant chemotherapy for locally advanced gastric carcinoma.

[Ogilvie's syndrome]. / La sindrome di Ogilvie.

Ogilvie's Syndrome is defined as acute distension of the colon without any mechanical obstruction. We reported two new cases who underwent surgical treatment and the revision of the literature. Four hundred eight-six cases are described until now. The physiopathology is unknown. The diagnosis is done with abdominal x-ray, barium enema must be used with attention. The more frequent symptoms are nausea, vomiting, diarrhea, and abdominal pain. The perforation of the colon is possible with a diameter of 9-12 cm. The mortality was 11.3% in two hundred ninety patients (59.6%) who underwent conservative treatment. In one hundred ninety-six patients who underwent surgical treatment the mortality was 28.5%. The treatment is conservative, medical or endoscopic. The best surgical treatment is the tube cecostomy.

[Abdominal wall metastasis of pancreatic adenocarcinoma following laparoscopy]. / Metastasi della parete addominale da adenocarcinoma del pancreas in seguito a laparoscopia.

Wound recurrence after oncologic surgery is known since 1885, but nowadays we deal with a new problem after the rapid diffusion of laparoscopically assisted surgery and the 22 cases of trocar site metastases already reported in literature. Aim of this paper is to present a case of cutaneous seeding of adenocarcinoma of the pancreas, in two trocar sites, after laparoscopy for lithiasis of the gallbladder. Diagnosis of neoplasia was made intraoperatively for the presence of peritoneal and omental carcinomatosis; no cholecystectomy was performed and after biopsy and postoperative TC-scan a chemotherapeutic treatment was started. Five months after the operation parietal seeding was evident and treated with local radiotherapy; the patient died one month later for further dissemination of the disease. The etiopathogenesis of tumor recurrence in the abdominal scar tissue is still unknown, local (trauma) and general (decreased immunologic defences) factors could be responsible. The apparent higher incidence after laparoscopic surgery could presuppose the presence of further specific risks: more tissue manipulation (increased cellular exfoliation), contact between trocar and abdominal wall for the whole operative period (malignant cell carrier), pneumoperitoneum. In conclusion, as 50% of the patients with cutaneous metastases die within 6 months after the operation and almost nobody is still alive after 4 years, it is necessary to establish if a real additional risk, due to the laparoscopic procedure, exists to contrast eventual benefits of the mini-invasive procedure.

Hepatobiliary anatomy in patients with transposition of the gallbladder: implications for safe laparoscopic cholecystectomy.

The surgical anatomy of six patients with sinistroposition of the gallbladder is described. Five of these were encountered in a consecutive series of 1764 patients undergoing laparoscopic cholecystectomy for symptomatic gallstone disease in two hospitals between 1989 and 1994, a prevalence of 0.3 per cent in patients undergoing this operation. Despite the left-sided transposition of the gallbladder, the biliary pain experienced by these patients was always on the right side. Preoperative diagnosis of this anomaly was made in only one of six patients despite routine preoperative external ultrasonography and selective preoperative cholangiography. In sinistroposition the cystic artery always crosses in front of the common bile duct from right to left. The cystic duct may open on the left or right side of the common hepatic duct. The anomaly does not preclude safe laparoscopic cholecystectomy but modifications of the port sites and use of the falciform lift facilitate the procedure in these cases. The anatomical features of the sixth case encountered in a patient undergoing resection of hilar cholangiocarcinoma indicate that sinistroposition of the gallbladder may be due to failure of development of segment IV of the liver.
