Abstract
Unplanned conversion (UPC) is considered to be a predictor of poor postoperative outcomes. However, the effects of UPC on the survival of patients with hepatocellular carcinoma (HCC) remain controversial. The aim of this study is to compare the outcomes between patients who underwent laparoscopic liver resection (LLR) and those who underwent UPC for HCC. Among 1029 patients with HCC who underwent hepatectomy between 2004 and 2021, 251 were eligible for the study. Of 251 patients who underwent hepatectomy for HCC in PS segments, 29 (26.0%) required UPC, and 222 underwent LLR. After 1:5 PSM, 25 patients were selected for the UPC group and 125 for the LLR group. Blood loss, transfusion rate, hospital stay, and postoperative complication were higher in the UPC group. Regarding oncologic outcomes, although the 5-year overall survival rate was similar in both groups (p = 0.544), the recurrence-free survival rate was lower in the UPC group (p < 0.001). UPC was associated with poor short-term as well as inferior long-term outcomes compared with LLR for HCC in PS segments. Therefore, surgeons must carefully select patients and consider early conversion if unexpected bleeding occurs to maintain safety and oncologic outcomes.

Abstract
Introduction: Laparoscopic appendectomy is the most preferred surgical method in the treatment of acute appendicitis. In our study, we aim to determine the clinical and radiological factors affecting conversion from laparoscopic appendectomy to open surgery. Materials and Methods: All patients older than 18 years, who were operated on with the diagnosis of acute appendicitis in the General Surgery clinic of Prof. Dr. İlhan Varank Training and Research hospital between January 2020 and January 2022, were included in the study. The data consisting of clinical, laboratory, and radiological (computed tomography) findings of the patients were evaluated retrospectively. The patients were divided into two groups as those whose surgery was completed laparoscopically (Group 1) and those converted from laparoscopic appendectomy to open surgery (Group 2). The risk of conversion to open surgery was analyzed by binary logistic regression analysis as univariate and multivariate models. Results: Appendectomy was performed in 831 patients within the specified period. The surgery of 31 (3.73%) patients started laparoscopically; however, they were completed by converting to open surgery. Multivariable analysis showed that the risk of conversion to open surgery increased with leukocyte count, Alvarado score and with the presence of periappendiceal fluid and lymphadenopathy on CT. Conclusion: Our study shows that patients with high risk of returning to open surgery can be identified preoperatively with the risk analysis method in which clinical, laboratory, and radiological findings are evaluated together. We conclude that, starting the operation of these patients with the open technique from the beginning will prevent unnecessary expenditures and reduce morbidities.

Abstract
Background: Study aims to demonstrate single-institution two decades experience with lateral transperitoneal laparoscopic adrenalectomies. Methods: Retrospective study involved 991 operations grouped into 4 cohorts. Data was collected on the patients’ age, sex, side and size of the lesion, histopathological type, hormonal activity, conversion to open adrenalectomy, operating time, length of hospital stay, perioperative complications. Results: The operations were right-sided (n = 550), left-sided (n = 422), bilateral (n = 19). Mean tumor size was 41.9 mm. Histopathological examination revealed 442 adenomas, 191 nodular hyperplasias, 218 pheochromocytomas, 33 malignancies and 126 other lesions. 541 patients had hormonally active tumors. Mean operating time for unilateral laparoscopic adrenalectomy was 141 min. Mean length of hospital stay was 5.27 days. Intraoperative complications rate was 2.3%. Conversion rate was 1.5%. 54 of patients had 70 postoperative complications. Reoperation rate was 1%. Mortality rate was 0.1%. Statistically significant differences were found in all factors, apart from age, sex, side and size of the lesion, reoperations rate (p > 0.05). Conversions rate, complications rates, length of hospital stay were highest in the first group (p < 0.05). Operating time shortened in the first decade. Conclusions: Laparoscopic adrenalectomy is a safe procedure with negligible mortality. Conversions rate, perioperative complications rate, and length of hospital stay, significantly decreased over time.

Abstract
BACKGROUND The benefits of pure laparoscopic and robot-assisted liver resections (LLR and RALR) are known in comparison to open surgery. The aim of the present retrospective comparative study is to investigate the role of RALR and LLR according to different levels of difficulty. METHODS The institutional databases of six high-volume hepatobiliary centers were retrospectively reviewed. The study population was divided in two groups: LLR and RALR. The procedures were stratified for difficulty levels accordingly to three classifications. A propensity score matching was implemented to mitigate selection bias. Short-term outcomes were the object of comparison. RESULTS Nine hundred and thirty-six LLR and 403 RALR were collected. RALR exhibited fewer cases of intraoperative blood loss, lower transfusion and conversion rates (especially for oncological radicality) than LLR in the setting of highly difficult operations, whereas LLR had lower postoperative morbidity and fewer low-grade complications. For intermediate and low-difficulty resections, the intraoperative advantages of RALR gradually decreased to nonsignificant results and LLR remained associated with lower postoperative morbidity. CONCLUSION Robot-assisted liver resections do not show operative nor clinically significant benefits over LLR for low- and intermediate-difficulty resections. By reducing conversion rates, RALR can favour the operative feasibility of difficult resections possibly extending the indications of minimally invasive approaches for liver resection.

Abstract
Objective To investigate the incidence of surgical site infection(SSI)following conversion from laparoscopic to open cholecystectomy and to analyze the related risk factors. Methods The clinical data of 179 patients who had experienced conversion from laparoscopic to open cholecystectomy in Peking Union Medical College Hospital from January 2014 to August 2019 were analyzed retrospectively.Univariate and multivariate logistic regression analyses were performed to evaluate the associations between clinical variables and SSI. Results The incidence of SSI was 19.0%(34/179)after conversion from laparoscopic to open cholecystectomy.The multivariable analysis demonstrated that preoperative endoscopic retrograde cholangiopancreatography(ERCP)(OR=4.208,95% CI:1.590-11.135,P=0.004)was the only independent risk factor of SSI. Conclusions The incidence of SSI after conversion from laparoscopic to open cholecystectomy increased remarkably,especially in those who had preoperative ERCP.Preventive interventions should be taken to reduce the incidence of SSI.

Abstract
Introduction: Minimally invasive surgery (MIS) in pediatric surgery is now the standard of care for various surgical conditions. We have seen an increase in MIS with some of the procedures requiring intraoperative conversion to open surgery. Materials and Methods: This is a single-institution retrospective study of patients who underwent MIS between 2009 and 2017 requiring conversion to open surgery. Preoperative characteristics, cause of conversion, and postoperative factors were recorded. Results: A total of 154 patients had converted to MIS, 89.6% underwent laparoscopic procedures. Mean age was 8.5 years, 53.9% were male. Primary cause leading to surgery was not oncologic (89.6%), dirty contaminated wound was found in 49.35%, inflammatory response markers were altered, and 38.9% of our patients were American Society of Anesthesiologists physical status classification 3. Principal causes of conversion were failure in progression (53.25%) and loss of anatomic reference (24.5%). A total of 44.16% of the patients required postoperative pediatric intensive care unit admission, 29.2% required reintervention, and mortality rate was 0.65%. We detailed data regarding thoracoscopic, appendectomy, and laparoscopic procedures. Conclusion: Conversion to MIS is a decision the surgeon must make in different scenarios. This study allowed us to characterize our population regarding converted MIS procedures. Male gender, age group, altered inflammatory markers, not oncologic pathology, and dirty wound were frequently found, but we cannot establish any of them as risk factors. Main cause for conversion to open surgery was failure in the progression of the procedure in our study according to reported literature. We intend to develop further studies to determine risk factors.

Abstract
BACKGROUND Biliary pancreatitis (BP) constitutes 30-55% of all cases of acute pancreatitis. Laparoscopic cholecystectomy (LC) has become the gold standard for the surgical treatment of gallbladder disease. We aimed to compare and evaluate the relation between the timing of LC and the rates and reasons of conversion to open surgery (OS) after BP. METHODS Data were collected of patients who presented for the first time with acute BP and underwent LC. The patients were divided into two groups: early cholecystectomy (Group 1), patients who underwent cholecystectomy during the first pancreatitis attack upon admission and before discharge from hospital (1-3 days); and late cholecystectomy (Group 2), patients who received medical treatment during their first pancreatitis episode and underwent surgery after 4-10 weeks. Sex, Ranson scores, American Society of Anesthesiology scores, and conversion reasons were compared. RESULTS Group 1 and Group 2 included 75 patients (20 men, 55 women) and 87 patients (25 men, 62 women), respectively. The mean age was 44.7 years (range, 21-82 years). Obscure anatomy with adhesions was detected in 16 patients (5 in Group 1, 11 in Group 2) as the leading cause of conversion to OS, but it was not statistically significant (p=0.054). Acute inflammation with empyema and peripancreatic liquid collection was observed in 14 patients (12 in Group 1, 2 in Group 2), and conversion to OS was statistically significantly higher in Group 1 (p=0.016). CONCLUSION Timing of LC does not influence the conversion rates to OS after BP.

Abstract
PURPOSE We sought to identify the preoperative factors associated with conversion from robotic partial nephrectomy to radical nephrectomy. We report the incidence of this event. MATERIALS AND METHODS Using our institutional review board approved database, we abstracted data on 1,023 robotic partial nephrectomies performed at our center between 2010 and 2015. Standard and converted cases were compared in terms of patients and tumor characteristics, and perioperative, functional and oncologic outcomes. Logistic regression analysis was done to identify predictors of radical conversion. RESULTS The overall conversion rate was 3.1% (32 of 1,023 cases). The most common reasons for conversion were tumor involvement of hilar structures (8 cases or 25%), failure to achieve negative margins on frozen section (7 or 21.8%), suspicion of advanced disease (5 or 15.6%) and failure to progress (5 or 15.6%). Patients requiring conversion were older and had a higher Charlson score (both p <0.01), including an increased prevalence of chronic kidney disease (p = 0.02). Increasing tumor size (5 vs 3.1 cm, p <0.01) and R.E.N.A.L. (radius, exophytic/endophytic properties, nearness of tumor to collecting system or sinus, anterior/posterior, location relative to polar lines and hilar location) score (9 vs 8, p <0.01) were also associated with an increased risk of conversion. Worse baseline renal function (OR 0.98, 95% CI 0.96-0.99, p = 0.04), large tumor size (OR 1.44, 95% CI 1.22-1.7, p <0.01) and increasing R.E.N.A.L. score (p = 0.02) were independent predictors of conversion. Compared to converted cases, at latest followup standard robotic partial nephrectomy cases had similar short-term oncologic outcomes but better renal functional preservation (p <0.01). CONCLUSIONS At a high volume center the rate of robotic partial nephrectomy conversion to radical nephrectomy was 3.1%, including 2.2% of preoperatively anticipated nephrectomy cases. Increasing tumor size and complexity, and poor preoperative renal function are the main predictors of conversion.

Abstract
AIM The aim of this study was to prospectively assess the outcome of early laparoscopic cholecystectomy (LC) in patients with acute cholecystitis. MATERIALS AND METHODS Between July 2005 and December 2012, of 623 patients who had symptoms of acute cholecystitis during the first 72 h of hospital admission and who did not respond to non-operative treatment, 302 underwent surgical treatment. After initial treatment, all patients were followed up for 21 months on average (range: 5-27 months). The clinical, biochemical, radiological, and operative data of the 302 consecutive patients with acute cholecystitis were recorded and analyzed prospectively. RESULTS Of the 302 patients who underwent LC for acute cholecystitis, 169 were females and 133 males. Their mean ages were 47.8 years (range: 17-79 years) and 53.3 years (range: 27-90 years) respectively. Conversion to open surgery was required in 32 patients (10.5%). The mean postoperative length of hospital stay was 2 days (range: 1-3 days) in the LC group and 3 days (range: 2-6 days) in the conversion group. Significant differences between the successful LC group and the conversion group were evident terms of the length of postoperative hospitalization and gallbladder wall thickness (P=0.023). Factors associated with conversion were male gender, pericholecystic collection observed via ultrasound, gangrenous cholecystitis, and gallbladder wall thickness >1 cm. We experienced two minor bile duct injury complications that were treated via T tube placement. No mortality occurred. Ten patients suffered infections at the incisional locations, and eight patients developed lung infections. CONCLUSION Early LC is safe in patients with acute cholecystitis. Male gender, pericholecystic collection determined via ultrasound, gangrenous cholecystitis, and gallbladder wall thickness >1 cm are associated with a higher risk of conversion to open surgery.

Abstract
BACKGROUND Colorectal cancer including rectal cancer is the third most common cause of cancer deaths in the western world. For colon carcinoma, laparoscopic surgery is proven to result in faster postoperative recovery, fewer complications and better cosmetic results with equal oncologic results. These short-term benefits are expected to be similar for laparoscopic rectal cancer surgery. However, the oncological safety of laparoscopic surgery for rectal cancer remained controversial due to the lack of definitive long-term results. Thus, the expected short-term benefits can only be of interest when oncological results are at least equal. OBJECTIVES To evaluate the differences in short- and long-term results after elective laparoscopic total mesorectal excision (LTME) for the resection of rectal cancer compared with open total mesorectal excision (OTME). SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library 2013, Issue 2), MEDLINE (January 1990 to February 2013), EMBASE (January 1990 to February 2013), ClinicalTrials.gov (February 2013) and Current Controlled Trials (February 2013). We handsearched the reference lists of the included articles for missed studies. SELECTION CRITERIA Only randomised controlled trials (RCTs) comparing LTME and OTME, reporting at least one of our outcome measures, was considered for inclusion. DATA COLLECTION AND ANALYSIS Two authors independently assessed study quality according to the CONSORT statement, and resolved disagreements by discussion. We rated the quality of the evidence using GRADE methods. MAIN RESULTS We identified 45 references out of 953 search results, of which 14 studies met the inclusion criteria involving 3528 rectal cancer patients. We did not consider the risk of bias of the included studies to have impacted on the quality of the evidence. Data were analysed according to an intention-to-treat principle with a mean conversion rate of 14.5% (range 0% to 35%) in the laparoscopic group.There was moderate quality evidence that laparoscopic and open TME had similar effects on five-year disease-free survival (OR 1.02; 95% CI 0.76 to1.38, 4 studies, N = 943). The estimated effects of laparoscopic and open TME on local recurrence and overall survival were similar, although confidence intervals were wide, both with moderate quality evidence (local recurrence: OR 0.89; 95% CI 0.57 to1.39 and overall survival rate: OR 1.15; 95% CI 0.87 to1.52). There was moderate to high quality evidence that the number of resected lymph nodes and surgical margins were similar between the two groups.For the short-term results, length of hospital stay was reduced by two days (95% CI -3.22 to -1.10), moderate quality evidence), and the time to first defecation was shorter in the LTME group (-0.86 days; 95% CI -1.17 to -0.54). There was moderate quality evidence that 30 days morbidity were similar in both groups (OR 0.94; 95% CI 0.8 to 1.1). There were fewer wound infections (OR 0.68; 95% CI 0.50 to 0.93) and fewer bleeding complications (OR 0.30; 95% CI 0.10 to 0.93) in the LTME group.There was no clear evidence of any differences in quality of life after LTME or OTME regarding functional recovery, bladder and sexual function. The costs were higher for LTME with differences up to GBP 2000 for direct costs only. AUTHORS' CONCLUSIONS We have found moderate quality evidence that laparoscopic total mesorectal excision (TME) has similar effects to open TME on long term survival outcomes for the treatment of rectal cancer. The quality of the evidence was downgraded due to imprecision and further research could impact on our confidence in this result. There is moderate quality evidence that it leads to better short-term post-surgical outcomes in terms of recovery for non-locally advanced rectal cancer. Currently results are consistent in showing a similar disease-free survival and overall survival, and for recurrences after at least three years and up to 10 years, although due to imprecision we cannot rule out superiority of either approach. We await long-term data from a number of ongoing and recently completed studies to contribute to a more robust analysis of long-term disease free, overall survival and local recurrence.

Abstract
BACKGROUND A pneumoperitoneum of 12 to 16 mm Hg is used for laparoscopic cholecystectomy. Lower pressures are claimed to be safe and effective in decreasing cardiopulmonary complications and pain. OBJECTIVES To assess the benefits and harms of low pressure pneumoperitoneum compared with standard pressure pneumoperitoneum in people undergoing 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 trials,using search strategies. SELECTION CRITERIA We considered only randomised clinical trials, irrespective of language, blinding, or publication status for inclusion in the review. DATA COLLECTION AND ANALYSIS Two review authors independently identified trials and independently extracted data. We calculated the risk ratio (RR), mean difference (MD), or standardised mean difference (SMD) with 95% confidence intervals (CI) using both fixed-effect and random-effects models with RevMan 5 based on available case analysis. MAIN RESULTS A total of 1092 participants randomly assigned to the low pressure group (509 participants) and the standard pressure group (583 participants) in 21 trials provided information for this review on one or more outcomes. Three additional trials comparing low pressure pneumoperitoneum with standard pressure pneumoperitoneum (including 179 participants) provided no information for this review. Most of the trials included low anaesthetic risk participants undergoing elective laparoscopic cholecystectomy. One trial including 140 participants was at low risk of bias. The remaining 20 trials were at high risk of bias. The overall quality of evidence was low or very low. No mortality was reported in either the low pressure group (0/199; 0%) or the standard pressure group (0/235; 0%) in eight trials that reported mortality. One participant experienced the outcome of serious adverse events (low pressure group 1/179, 0.6%; standard pressure group 0/215, 0%; seven trials; 394 participants; RR 3.00; 95% CI 0.14 to 65.90; very low quality evidence). Quality of life, return to normal activity, and return to work were not reported in any of the trials. The difference between groups in the conversion to open cholecystectomy was imprecise (low pressure group 2/269, adjusted proportion 0.8%; standard pressure group 2/287, 0.7%; 10 trials; 556 participants; RR 1.18; 95% CI 0.29 to 4.72; very low quality evidence) and was compatible with an increase, a decrease, or no difference in the proportion of conversion to open cholecystectomy due to low pressure pneumoperitoneum. No difference in the length of hospital stay was reported between the groups (five trials; 415 participants; MD -0.30 days; 95% CI -0.63 to 0.02; low quality evidence). Operating time was about two minutes longer in the low pressure group than in the standard pressure group (19 trials; 990 participants; MD 1.51 minutes; 95% CI 0.07 to 2.94; very low quality evidence). AUTHORS' CONCLUSIONS Laparoscopic cholecystectomy can be completed successfully using low pressure in approximately 90% of people undergoing laparoscopic cholecystectomy. However, no evidence is currently available to support the use of low pressure pneumoperitoneum in low anaesthetic risk patients undergoing elective laparoscopic cholecystectomy. The safety of low pressure pneumoperitoneum has to be established. Further well-designed trials are necessary, particularly in people with cardiopulmonary disorders who undergo laparoscopic cholecystectomy.

Abstract
OBJECTIVES Although laparoscopic cholecystectomy has become the standard treatment for symptomatic gallbladder diseases, conversion to open surgery is required in a substantial proportion of patients. In this study, we attempted to clarify whether male sex carries an increased risk for conversion to open surgery during laparoscopic cholecystectomy. METHODS This study comprised 80 patients (41 females, 39 males) with symptomatic gallbladder stones. Average age was 39.2 years, and all female patients were of reproductive age. Patients were excluded from the study if they had acute cholecystitis, previous abdominal surgery, systemic or connective tissue diseases, or were using tobacco, alcohol, or medications that affect wound healing or inflammation. Tissue samples were obtained from the same sites in each gallbladder wall and pericholecystic tissue for the measurement of tissue hydroxyproline (HP) and collagen. Samples were examined under light microscopy for histopathology. Findings in male and female patients were compared by using the Student t test. RESULTS All patients except 3 males received laparoscopic cholecystectomy. Conversion to open cholecystectomy was necessary in those 3 because of intense pericholecystic fibrosis. In male patient samples, macrophages were twice as numerous as in female samples, whereas mast cells in the men were 4 times more numerous, and eosinophils were 6 times more numerous (P<0.01). In men, HP levels in the gallbladder wall and pericholecystic tissue were 23.4+/-14.9 microg/mg dry tissue and 25.2+/-13.1 microg/mg dry tissue, respectively. The corresponding values in women were 13.1+/-9.4 microg/mg dry tissue and 14.5+/-8.1 microg/mg dry tissue. This higher level of tissue HP in men was statistically significant (P<0.015). Tissue collagen levels both in the submucosal area of the gallbladder wall and in pericholecystic tissue were significantly higher in men than in women (P<0.05). CONCLUSION Our data suggest that in the context of symptomatic gallbladder stones, inflammation and fibrosis are more extensive in men than in women. These findings may help explain why the rate of conversion to open surgery is higher in men than in women.
