    ABSTRACT: BACKGROUND: Single-incision laparoscopic cholecystectomy (SILC) is gaining popularity. It is not evident whether the benefits of this procedure overcome the potential increased risk. We performed a systematic review and meta-analysis to compare SILC with conventional multi-incision laparoscopic cholecystectomy (MILC). METHODS: Data from randomized, controlled trials published up to December 2011 and comparing SILC versus MILC were extracted. The primary end point was overall morbidity. A fixed-effect model was applied to summarize the study outcomes in the meta-analysis, and a random-effect model was used in the sensitivity analysis. The outcome measures were relative risk (RR) and mean difference (MD); a RR of <1.0 or a negative MD indicated a more favorable outcome after SILC. Publication bias was assessed by a funnel plot, and heterogeneity was tested by the I (2) measure and subgroup analyses. RESULTS: A total of 12 trials (996 patients) were included. Mortality was nil in both treatment groups; the overall RR for morbidity was 1.36 (p = 0.098). The mean operating time was 47.2 min for MILC and 58.1 min for SILC (MD 9.47 min; p < 0.001). The visual analog scale pain score at 24 h after surgery was 2.96 in MILC and 2.34 in SILC (MD -0.64; p = 0.058), but sensitivity analysis of the four studies deemed at low risk of bias for pain assessment, according to blinding and postoperative analgesic protocols, showed significance at -0.43 points (95 % confidence interval -0.87 to 0.00; p = 0.049). Cosmetic outcome scored better in the SILC group, with its standardized MD being equal to 1.16 (95 % confidence interval 0.57 to 1.75; p < 0.001). CONCLUSIONS: In selected patients, SILC has similar overall morbidity compared with MILC; further, it results in better cosmetic satisfaction and reduced postoperative pain despite longer operative time.

    ABSTRACT: BACKGROUND: The ideal management of cholelithiasis and common bile duct stones still is controversial. Although the two-stage sequential approach remains the prevalent management, several trials have concluded that the so-called laparoendoscopic rendezvous (LERV) technique offers some advantages, such as a reduced risk of post-ERCP (endoscopic retrograde cholangiopancreatography) pancreatitis. This study aimed to compare the single-stage LERV technique with the two-stage endoscopic sphincterotomy followed by laparoscopic cholecystectomy. METHODS: A search for randomized controlled trials (RCTs) comparing LERV and the two-stage sequential approach was conducted. The outcomes considered were overall complications and pancreatitis. Medline, EMBASE, and the Cochrane Central Register of Controlled Trials (CENTRAL) were searched from 1998 to July 2012. Odds ratios (ORs) were extracted and pooled using a fixed or random-effect model depending on I (2) used as a heterogeneity measure. RESULTS: Four RCTs, including a total of 430 patients, met the inclusion criteria. The incidence of overall complications was lower in the LERV group (11.2 %) than in the two-stage intervention group (18.1 %) (OR, 0.56; 95 % confidence interval [CI], 0.32-0.99; P = 0.04; I (2) = 45 %). The findings showed that LERV was associated with less clinical pancreatitis (2.4 %) than the two-stage technique (8.4 %) (OR, 0.33; 95 % CI, 0.12-0.91; P = 0.03; I (2) = 33 %). CONCLUSIONS: Despite the limitation of a small number of studies completed, the evidence of RCTs shows that LERV is superior to two-stage treatment due to a reduction in overall complications, particularly pancreatitis.

    ABSTRACT: BACKGROUND: Peritoneal perforation (PP) is frequently reported as a complication of transanal endoscopic microsurgery (TEM). Nevertheless, these concerns have only rarely been addressed in the literature, with no mention of the long-term oncologic consequences of PP. METHODS: A prospective database was analyzed with the intent to evaluate the influence of PP on the short- and long-term outcomes for patients undergoing TEM. RESULTS: Peritoneal perforation occurred in 28 (5.8 %) of 481 patients who underwent TEM for a rectal neoplasm. The conversion rate to abdominal surgery was 10.7 % (3/28). All the conversions occurred during the first 100 TEM procedures (3/100 vs 0/381; p = 0.007). The postoperative morbidity rate was 3.6 % (1/28), and the 30-day mortality was nil. Compared with the group of patients who had no peritoneal perforation, the PP group showed a significantly longer operating time (120 vs 60 min; p < 0.001) and a significantly longer hospital stay (6 vs 4 days; p = 0.003). Nevertheless, the global morbidity rate and the type of complications according to Dindo's classification were similar. In the multivariate analysis, the only independent predictor of PP was tumor distance from the anal verge (p = 0.010). During a median follow-up period of 48 months (range, 12-150 months), no liver or peritoneal metastases were detected in 13 patients with rectal cancer. CONCLUSIONS: Peritoneal perforation does not seem to affect short-term or oncologic outcomes for patients submitted to TEM with full-thickness resection for upper rectum neoplasms. The use of TEM to resect rectal lesions involving the intraperitoneal rectum may therefore represent an intermediate step toward the development of transrectal natural orifice translumenal endoscopic surgery (NOTES) techniques.

    ABSTRACT: Transanal endoscopic microsurgery (TEM) has revolutionized the technique and outcome of transanal surgery, becoming the standard of treatment for large sessile rectal adenomas. Nevertheless, only a few studies have evaluated the risk factors for local recurrence in order to recommend a "tailored" approach. The aim of this study was to identify predictor variables for recurrence after TEM to treat rectal adenoma. This study is a retrospective analysis of a prospective database of patients treated for large sessile rectal adenomas by TEM at our institution, with a minimum follow-up of 12 months. Age, gender, tumor diameter, distance from the anal verge, degree of dysplasia, histology, and margin involvement were investigated. Between January 1993 and July 2010, 293 patients with a rectal adenoma ≥3 cm underwent TEM. Postoperative morbidity rate was 7.2 % (21/293) and there was no 30-day mortality. Over a median follow-up period of 110 (range = 12-216) months, 13 patients (5.6 %) were diagnosed with local recurrence. The median time to recurrence was 10 (range = 4-33) months, with 76.9 % of recurrences detected within 12 months after TEM. At univariate analysis, tumor diameter (p = 0.007), and positive margins (p < 0.001) were shown to be significant risk factors, while multivariate analysis indicated the presence of positive margins as the only independent predictor of recurrence (p = 0.003). TEM provides excellent oncological outcomes in the treatment of large sessile benign rectal lesions, assuring a minimal risk of resection margin infiltration at pathology examination, which represents the only risk factor for recurrence.

    ABSTRACT: Surgical techniques and technologies are rapidly evolving. In the field of colorectal surgery the transanal video-assisted approach was introduced by Buess, 30 years ago, with transanal endoscopic microsurgery (TEM). In more recent years different techniques and technologies have been proposed, including natural orifice specimen extraction (NOSE), natural orifice transluminal endoscopic surgery (NOTES) and single-access surgery. Furthermore, a better understanding of the prognostic and risk factors of rectal cancer has allowed TEM to expand its indications to local resection of selected tumours, and more recently there have been proposals for sentinel node biopsy in colon and rectal cancer.

    ABSTRACT: To evaluate the long-term results of laparoscopic vertical banded gastroplasty (VBG) for morbid obesity. Laparoscopic VBG, a safe and straightforward bariatric procedure characterized by good short-term results, has been progressively replaced by other more complex procedures on the basis of a presumed high rate of long-term failure. Nevertheless, some authors have recently reported long-term efficacy in selected patients. All patients who underwent laparoscopic VBG were included in a prospective database. Patients reaching 10-year follow-up received a complete evaluation including clinical, endoscopic, and biochemical examinations. Between January 1996 and March 1999, 266 morbidly obese patients underwent bariatric procedures. Among them, 213 were selected for laparoscopic VBG; exclusion criteria were as follows: contraindications to pneumoperitoneum, gastroesophageal reflux disease, and psychological contraindications to restrictive procedures. Mean age, preoperative weight, and body mass index were 36.9 years, 123.6 kg, and 45.4 kg/m, respectively. Intraoperative complication rate and conversion rate were 0.9% and 0.9%, respectively. Early postoperative complication rate was 4.2% and early reoperation rate was 0.5%. Mean hospital length of stay was 6.3 days. Mortality was nil. The 10-year follow-up rate was 70.4% (150 patients). Late postoperative complication rate was 14.7%, and 10-year revisional surgery rate was 10.0%. The excess weight loss percentages at 3, 5, and 10 years were 65.0%, 59.9%, and 59.8%, respectively. The resolution and/or improvement rate for comorbidity were 47.5% for hypertension, 55.6% for diabetes, 75% for sleep apnea, and 47.4% for arthritis. Mean Moorehead-Ardelt Quality of Life Questionnaire and BAROS values were 1.4 and 3.8, respectively. The present study demonstrates that laparoscopic VBG in carefully selected patients leads to long-term results comparable with more complex and invasive procedures. Given the low postoperative morbidity for laparoscopic VBG, its present clinical role should be, in our opinion, reevaluated.

    ABSTRACT: Since its first description in 1991, laparoscopic Heller myotomy has been associated with better short-term outcomes and shorter recovery time, compared to open operation and it is now generally accepted as the procedure of choice for achalasia. Despite the well-known short-term benefits of laparoscopy, esophageal perforation still occurs. Robotic technology has recently been introduced into laparoscopic clinical practice with the aim of improving surgical performance and excellent results have been described with robotically assisted Heller myotomy in patients with achalasia. The 3-D visualization, the very steady operative view and, above all, the articulated arms of the da Vinci Robotic Surgical System allow the surgeon to visualize and divide each individual muscolar fiber, easily identifying the submucosal plane at the GE junction. However, no high-quality studies are available in literature. Moreover, from an economic point of wiew, the use of the robotic technology may increase both the costs and the volume of surgeries performed. Achalasia, Robotically assisted myotomy.
