RESUMO
BACKGROUND: Laparoscopy has rapidly emerged as the preferred surgical approach for a number of different diseases because it allows for a correct diagnosis and proper treatment. However, it is not being applied in a widespread manner for the management of benign or malignant colorectal disease. Its natural evolution seems to be the development of mini-instruments and optics (diameter, =5 mm). This study aimed to illustrate retrospectively the results of an initial minilaparoscopic colorectal surgery experience at two different institutions. METHODS: Between January 2001 and December 2006, a total of 517 patients underwent a laparoscopic colon procedure. Among them, 161 (31.1%) underwent surgery with mini-instruments. The primary end point was the feasibility rate for minilaparoscopic colon resection. The secondary end points were safety and the impact of the technique on the duration of laparoscopy. RESULTS: No conversion to classical laparoscopy and eight cases converted to the open approach were registered. The rate for major complications was 3.1%, whereas the rate for minor complications ranged as high as 11.8%. CONCLUSIONS: Even if limited by its retrospective design, the reported experience shows that minilaparoscopic surgery may be a safe and effective approach to colon pathology. The described features make minilaparoscopy a challenging alternative to laparoscopy for colon disease. If proven to be cost effective without undue risk, as long as adequate training is obtained and proper preparation is observed, minilaparoscopy may become a standard surgical approach for selected patients.

BACKGROUND: The management of patients with colorectal cancer (CRC) and synchronous liver metastases (SLM) depends on the primitive tumor, resectability of the metastatic disseminations and the patient's comorbid condition(s). Considering all patients with potentially resectable primary CRC and SLM, curative resection (R0) will be possible in some patients, although in others surgery will never be performed. The purpose of our study was to identify factors of failure of the curative schedule in these patients. METHODS: We reviewed the data of patients with CRC and SLM between January 2002 and March 2007. Two groups were defined: group R0 when complete metastatic and primary tumor resection was finally achieved after one and more surgical stages and group R2 when curative resection was not possible at the end of the schedule. Clinical, pathologic and outcome data were retrospectively analyzed as well as preoperative management of SLM (chemotherapy, radiofrequency, portal vein embolization). RESULTS: Forty-five patients were included. Curative resection (group R0) was performed in 31 patients (69%) with 48% undergoing major hepatic resection. Mortality of hepatic resection was 0% although it was 9% for primitive tumor. Portal vein embolization was performed preoperatively in eight patients and radiofrequency ablation in 13. Median follow-up was 21 months. Overall survival was 86% at one year and 39% at three years. Survival in group 1 was 97 and 57% at one and three years respectively. Disease-free survival was 87 and 40% at one and three years. Tumor recurrence was noted in 61% of resected patients. At multivariate analysis, number of hepatic metastases superior than three and complicated initial presentation of primitive tumor were found to be significant and predictors of failure of hepatic resection. CONCLUSION: Aggressive management with curative resection of SLM may enable long-term survival. More than three SLM and complicated initial presentation of primitive tumor are factors predictive of failure of the curative schedule.

Interleukin-1 is an anorexigenic cytokine, and is involved in the pathogenesis of cancer anorexia. Interleukin-1 induced anorexia is mediated by direct action within the hypothalamus, and by peripheral mechanism(s) yet to be determined. Here we present evidence showing that in an animal model the peripheral injection of interleukin-1 is followed by a significant rise in brain tryptophan concentrations. Tryptophan is the precursor of the neurotransmitter serotonin, known to mediate the onset of satiety under normal and pathological conditions. By inference, we conclude that interleukin-1 induced anorexia is mediated by at least two different mechanism: i) interleukin-1 direct action within the hypothalamus; ii) increased brain serotonergic activity, secondary to interleukin-1 induced increased brain availability of the serotonin precursor, tryptophan.

The authors report the complex case of a 51 year-old man admitted to his local hospital for gallbladder and common bile duct lithiasis, 1 year before admission to our hospital. There, he was treated by cholecystectomy and transduodenal biliary sphincteroplasty. He was readmitted after 3 months because of a painful episode and was discharged with the diagnosis of "relapsing acute pancreatitis in chronic pancreatitis." At our hospital, he underwent laparotomy and revision of the previous transduodenal biliary sphincteroplasty. Pancreatic sphincteroplasty and septectomy were also performed. The night after surgery, the patient suffered from acute post-operative pancreatitis complicated by severe hemorrhage due to erosion of the superior pancreaticoduodenal arteries, treated with gastroduodenal artery embolization by tungsten coils. Three months later, the patient suffered from another acute episode. An endoscopic retrograde colangio pancreatography (ERCP) showed the complete patency of the sphincteroplasties but clearly identified the persistence of a severe cephalic stricture. Therefore, the patient was readmitted to our hospital and underwent another laparotomy. A pylorus-preserving pancreaticoduodenectomy (PPPD) was performed. The post-operative course was uneventful and at 14 months follow-up the patient was in good health. The discussion focuses on the surgical treatment of chronic pancreatitis with cephalic Wirsung duct stenosis, stressing the increasing role of PPPD as a first-choice option.

Blind insertion of the Veress needle and of the first trocar is a significant cause of laparoscopic surgery complications. Despite this risk, the closed technique is still more popular than the open one. The authors retrospectively evaluated 1006 consecutive laparoscopic operations in which Hasson's technique was routinely performed. The overall complication rate was 2.2%, but the vast majority of complications occurred during the first 50 cases (6% vs. 1.9%). They conclude that after a learning phase of about 50 cases, Hasson's technique is a quick and safe procedure.

Blind insertion of the Veress needle and/or the first trocar is one of the most frequent causes of laparoscopic surgery complications. Nevertheless, the closed technique is still more preferred than the open one. The Authors retrospectively analyzed 1006 consecutive laparoscopic procedures in which Hasson's technique was routinely utilized. The overall complication rate was 2.2%, but the vast majority of complications occurred during the learning curve (6% vs. 1.9%). The Authors conclude that after the first 50 cases the open technique is a quick and safe procedure.

This retrospective study compares recurrence and postoperative complication rates after isthmo-lobectomy and subtotal thyroidectomy (group I) vs near-total and total thyroidectomy (group II) for benign thyroid disease. Seven hundred and forty-three patients were operated on for thyroid diseases over the period from 1977 to 1998. We considered 202 patients operated on for benign thyroid disease from 1988 to 1998. The follow-up ranged from 1 to 10 years (mean: 3.4 yrs). One hundred and thirty-two patients (65.3%) were operated on for bilateral nodular goitre, 35 (17.3%) for unilateral nodular goitre, 14 (6.9%) for toxic goitre and 21 (10.4%) for thyroiditis. Over the period 1988-1992, 19 patients underwent isthmo-lobectomy and 71 subtotal thyroidectomy (group I). From 1993 to 1998, 39 patients underwent near-total thyroidectomy and 61 total thyroidectomy (group II). The relapse rate was 14.4% in group I, while there were no recurrences in group II (p = 0.000064). Temporary hypocalcaemia was significantly higher (p = 0.000001) in group II (29%) than in group I (2.2%). Within group II, the rate was significantly higher (p = 0.0013) after total thyroidectomy (37.7%) than after near-total thyroidectomy (15.4%). In our experience, near-total and total thyroidectomy are an appropriate approach for preventing recurrence in patients with benign thyroid disease despite the fact that the risk of temporary hypocalcaemia is higher than after less radical surgery. Near-total thyroidectomy and the exercise of all due care in the surgical technique may help to reduce its incidence.

Lymphangiomatosis confined to the spleen is a very are condition. The authors in this article describes one new case and briefly reviews the literature. In this case, after the exclusion of an hydatidosis of the spleen, a total splenectomy was performed. The histologic findings confirmed the lymphangiomatosis of the spleen. The authors emphasize the surgical strategy in splenic lymphangiomyomatosis, infact the total splenectomy is mandatory, because the splenic parenchyma is nearly completely substitute by the cysts. For this reason is preferably, before surgery, to perform the antibateric profilaxis against the OPSI.

Despite advances in surgery including new prosthetic materials and the advent of laparoscopy, the treatment of parastomal hernias remains a challenge for the surgeon. This is mainly due to the very high recurrence rate. Adequate management requires preoperative multidisciplinary consultation to offer the most appropriate surgical solution to each patient. We propose a review of current knowledge about this complication.
