Abstract
In some cases, laparoscopic cholecystectomy (LC) may be difficult to perform in patients with acute cholecystitis (AC) with severe inflammation and fibrosis. The Tokyo Guidelines 2018 (TG18) expand the indications for LC under difficult conditions for each level of severity of AC. As a result of expanding the indications for LC to treat AC, it is absolutely necessary to avoid any increase in bile duct injury (BDI), particularly vasculo-biliary injury (VBI), which is known to occur at a certain rate in LC. Since the Tokyo Guidelines 2013 (TG13), an attempt has been made to assess intraoperative findings as objective indicators of surgical difficulty; based on expert consensus on these difficulty indicators, bail-out procedures (including conversion to open cholecystectomy) have been indicated for cases in which LC for AC is difficult to perform. A bail-out procedure should be chosen if, when the Calot's triangle is appropriately retracted and used as a landmark, a critical view of safety (CVS) cannot be achieved because of the presence of nondissectable scarring or severe fibrosis. We propose standardized safe steps for LC to treat AC. To achieve a CVS, it is vital to dissect at a location above (on the ventral side of) the imaginary line connecting the base of the left medial section (Segment 4) and the roof of Rouvière's sulcus and to fulfill the three criteria of CVS before dividing any structures. Achieving a CVS prevents the misidentification of the cystic duct and the common bile duct, which are most commonly confused.

Abstract
OBJECTIVE To compare the outcomes between laparoendoscopic single-site (LESS) and a novel percutaneous externally assembled laparoscopic (PEAL) nephrectomy in an in vivo porcine model. MATERIALS AND METHODS Ten female farm pigs were randomized to LESS nephrectomy (5) or PEAL nephrectomy (5). Operative times, estimated blood loss, and intraoperative and postoperative complications were compared. The surgeons used a Likert scale to grade difficulty of peritoneal access, port placement, tool assembly, hilar dissection, closure, and overall difficulty of surgery. Scar assessment was performed by a blinded plastic surgeon using the Vancouver Scar Scale. Descriptive statistics were reported as median and range. The Mann-Whitney U test was used for continuous and ordinal variables. A p value <0.05 was considered significant. RESULTS Median operative time was significantly shorter in the PEAL group vs the LESS group (85 minutes vs 127 minutes, p = 0.03). Median Likert scores showed overall hilar dissection and nephrectomy to be significantly easier using PEAL compared with LESS (2 vs 9, p < 0.01 for both). The PEAL instruments left no visible scar at 5 feet in any animal, and only 1 out of 10 scars could be identified on physical examination. CONCLUSIONS The PEAL surgical paradigm demonstrates nearly scarless outcomes while providing shorter operative times and easier performance than LESS nephrectomy in a porcine model.

Abstract
BACKGROUND In conventional (standard) port laparoscopic cholecystectomy, four abdominal ports (two of 10 mm diameter and two of 5 mm diameter) are used. Recently, use of smaller ports, miniports, have been reported. OBJECTIVES To assess the benefits and harms of miniport (defined as ports smaller than the standard ports) laparoscopic cholecystectomy versus standard port laparoscopic cholecystectomy. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library, MEDLINE, EMBASE, and Science Citation Index Expanded until February 2013 to identify randomised clinical trials of relevance to this review. SELECTION CRITERIA Only randomised clinical trials (irrespective of language, blinding, or publication status) comparing miniport versus standard port laparoscopic cholecystectomy were considered for the review. DATA COLLECTION AND ANALYSIS Two review authors collected the data independently. We analysed the data with both fixed-effect and random-effects models using RevMan analysis. For each outcome we calculated the risk ratio (RR), mean difference (MD), or standardised mean difference (SMD) with 95% confidence intervals (CI). MAIN RESULTS We included 12 trials with 734 patients randomised to miniport laparoscopic cholecystectomy (380 patients) versus standard laparoscopic cholecystectomy (351 patients). Only one trial which included 70 patients was of low risk of bias. Miniport laparoscopic cholecystectomy could be completed successfully in more than 80% of patients in most trials. The remaining patients were mostly converted to standard port laparoscopic cholecystectomy but some were also converted to open cholecystectomy. These patients were included for the outcome conversion to open cholecystectomy but excluded from other outcomes. Accordingly, the results of the other outcomes are on 343 patients in the miniport laparoscopic cholecystectomy group and 351 patients in the standard port laparoscopic cholecystectomy group, and therefore the results have to be interpreted with extreme caution.There was no mortality in the seven trials that reported mortality (0/194 patients in miniport laparoscopic cholecystectomy versus 0/203 patients in standard port laparoscopic cholecystectomy). There were no significant differences between miniport laparoscopic cholecystectomy and standard laparoscopic cholecystectomy in the proportion of patients who developed serious adverse events (eight trials; 460 patients; RR 0.33; 95% CI 0.04 to 3.08) (miniport laparoscopic cholecystectomy: 1/226 (adjusted proportion 0.4%) versus standard laparoscopic cholecystectomy: 3/234 (1.3%); quality of life at 10 days after surgery (one trial; 70 patients; SMD -0.20; 95% CI -0.68 to 0.27); or in whom the laparoscopic operation had to be converted to open cholecystectomy (11 trials; 670 patients; RR 1.23; 95% CI 0.44 to 3.45) (miniport laparoscopic cholecystectomy: 8/351 (adjusted proportion 2.3%) versus standard laparoscopic cholecystectomy 6/319 (1.9%)). Miniport laparoscopic cholecystectomy took five minutes longer to complete than standard laparoscopic cholecystectomy (12 trials; 695 patients; MD 4.91 minutes; 95% CI 2.38 to 7.44). There were no significant differences between miniport laparoscopic cholecystectomy and standard laparoscopic cholecystectomy in the length of hospital stay (six trials; 351 patients; MD -0.00 days; 95% CI -0.12 to 0.11); the time taken to return to activity (one trial; 52 patients; MD 0.00 days; 95% CI -0.31 to 0.31); or in the time taken for the patient to return to work (two trials; 187 patients; MD 0.28 days; 95% CI -0.44 to 0.99) between the groups. There was no significant difference in the cosmesis scores at six months to 12 months after surgery between the two groups (two trials; 152 patients; SMD 0.13; 95% CI -0.19 to 0.46). AUTHORS' CONCLUSIONS Miniport laparoscopic cholecystectomy can be completed successfully in more than 80% of patients. There appears to be no advantage of miniport laparoscopic cholecystectomy in terms of decreasing mortality, morbidity, hospital stay, return to activity, return to work, or improving cosmesis. On the other hand, there is a modest increase in operating time after miniport laparoscopic cholecystectomy compared with standard port laparoscopic cholecystectomy and the safety of miniport laparoscopic cholecystectomy is yet to be established. Miniport laparoscopic cholecystectomy cannot be recommended routinely outside well-designed randomised clinical trials. Further trials of low risks of bias and low risks of random errors are necessary.
