ABSTRACT
BACKGROUND: Despite obesity being well known to be associated with several pituitary hormone imbalances, pituitary appearance in magnetic resonance imaging (MRI) in patients with obesity is understudied. OBJECTIVE: To evaluate the pituitary volume and signal intensity at MRI in patients with obesity. METHODS: This is a prospective study performed in an endocrine Italian referral center (ClinicalTrial.gov Identifier: NCT03458533). Sixty-nine patients with obesity (BMI > 30 kg/m2) and twenty-five subjects without obesity were enrolled. Thirty-three patients with obesity were re-evaluated after 3 years of diet and lifestyle changes, of whom 17 (51.5%) achieved a > 5% loss of their initial body weight, whereas the remaining 16 (48.5%) had maintained or gained weight. Evaluations included metabolic and hormone assessments, DEXA scan, and pituitary MRI. Pituitary signal intensity was quantified by measuring the pixel density using ImageJ software. RESULTS: At baseline, no difference in pituitary volume was observed between the obese and non-obese cohorts. At the 3-year follow-up, pituitary volume was significantly reduced (p = 0.011) only in participants with stable-increased body weight. Furthermore, a significant difference was noted in the mean pituitary intensity of T1-weighted plain and contrast-enhanced sequences between the obese and non-obese cohorts at baseline (p = 0.006; p = 0.002), and a significant decrease in signal intensity was observed in the subgroup of participants who had not lost weight (p = 0.012; p = 0.017). Insulin-like growth factor-1 levels, following correction for BMI, were correlated with pituitary volume (p = 0.001) and intensity (p = 0.049), whereas morning cortisol levels were correlated with pituitary intensity (p = 0.007). The T1-weighted pituitary intensity was negatively correlated with truncal fat (p = 0.006) and fibrinogen (p = 0.018). CONCLUSIONS: The CHIASM study describes a quantitative reduction in pituitary intensity in T1-weighted sequences in patients with obesity. These alterations could be explained by changes in the pituitary stromal tissue, correlated with low-grade inflammation.

AIM: The choice of whether to perform protective ileostomy (PI) after anterior resection (AR) is mainly guided by risk factors (RFs) responsible for the development of anastomotic leakage (AL). However, clear guidelines about PI creation are still lacking in the literature and this is often decided according to the surgeon's preferences, experiences or feelings. This qualitative study aims to investigate, by an open-ended question survey, the individual surgeon's decision-making process regarding PI creation after elective AR. METHOD: Fifty four colorectal surgeons took part in an electronic survey to answer the questions and describe what usually led their decision to perform PI. A content analysis was used to code the answers. To classify answers, five dichotomous categories (In favour/Against PI, Listed/Unlisted RFs, Typical/Atypical, Emotions/Non-emotions, Personal experience/No personal experience) have been developed. RESULTS: Overall, 76% of surgeons were in favour of PI creation and 88% considered listed RFs in the question of whether to perform PI. Atypical answers were reported in 10% of cases. Emotions and personal experience influenced surgeons' decision-making process in 22% and 49% of cases, respectively. The most frequently considered RFs were the distance of the anastomosis from the anal verge (96%), neoadjuvant chemoradiotherapy (88%), a positive intraoperative leak test (65%), blood loss (37%) and immunosuppression therapy (35%). CONCLUSION: The indications to perform PI following rectal cancer surgery lack standardization and evidence-based guidelines are required to inform practice. Until then, expert opinion can be helpful to assist the decision-making process in patients who have undergone AR for adenocarcinoma.

BACKGROUND: The identification of metastatic lymph nodes is one of the most important prognostic factors in gastrointestinal (GI) cancers. Near-infrared fluorescence (NIRF) imaging has been successfully used in GI tumors to detect the lymphatic pathway and the sentinel lymph node (SLN), facilitating fluorescence image-guided surgery (FIGS) with the purpose to achieve a correct nodal staging. The aim of this study was to analyze the current results of NIRF SLN navigation and lymphography through data collected in the EURO-FIGS registry. METHODS: Prospectively collected data regarding patients and ICG-guided lymphadenectomies were analyzed. Additional analyses were performed to identify predictors of metastatic SLN and determinants of fluorescence positivity and nodal metastases outside the boundaries of standard lymphadenectomies. RESULTS: Overall, 188 patients were included by 18 surgeons from 10 different centers. Colorectal cancer was the most reported pathology (77.7%), followed by gastric (19.1%) and esophageal tumors (3.2%). ICG was injected with higher doses (p < 0.001) via extraparietal side (63.3%), and with higher volumes (p < 0.001) via endoluminal side (36.7%). Overall, NIRF SLN navigation was positive in 75.5% of all cases and 95.5% of positive SLNs were retrieved, with a metastatic rate of 14.7%. NIRF identification of lymph nodes outside standard lymphatic stations occurred in 52.1% of all cases, 43.8% of which were positive for metastatic involvement. Positive NIRF SLN identification was an independent predictor of metastasis outside standard lymphatic stations (OR = 4.392, p = 0.029), while BMI independently predicted metastasis in retrieved SLNs (OR = 1.187, p = 0.013). Lower doses of ICG were protective against NIRF identification outside standard of care lymphadenectomy (OR = 0.596, p = 0.006), while higher volumes of ICG were predictive of metastatic involvement outside standard of care lymphadenectomy (OR = 1.597, p = 0.001). CONCLUSIONS: SLN mapping helps identifying potentially metastatic lymph nodes outside the boundaries of standard lymphadenectomies. The EURO-FIGS registry is a valuable tool to share and analyze European surgeons' practices.

BACKGROUND: Some authors consider adrenal lesions size of less than 4 cm as a positive cut-off limit to set the indications for minimally invasive surgery due to a lower risk of malignancy. Aim of this study is to report the risk of cancer for adrenal lesions measuring 4 cm or more in diameter, assessed as benign at preoperative workup (primary outcome), and to evaluate the feasibility and safety of laparoscopic adrenalectomy (LA) in these cases (secondary outcome). METHODS: From January 1994 to February 2019, 579 patients underwent adrenalectomy. Fifty patients with a preoperative diagnosis of primary adrenal cancer or metastases were excluded. The remaining 529 patients were included and divided in five subgroups based on adrenal lesion size at definitive histology: group A, 4-5.9 cm (137 patients); group B, 6-7.9 cm (64 patients); group C, 8-9.9 cm (13 patients); group D, ≥ 10 cm (11 patients); group E, < 4 cm (304 patients). Each group was further divided based on diagnosis of benign or malignant lesions at definitive histology. RESULTS: Four (2.9%) malignant lesions were observed in group A, 5 (7.8%) in group B, 2 (15.4%) in Groups C and D (18.2%) and 13 (4.3%) in Group E. Comparing the cancer risk among the groups, no statistically significant differences were observed. Operative time increased with increasing lesion size. However, no statistically significant differences were observed between benign and malignant lesions in each group comparing operative time, conversion and complication rates, postoperative hospital stay and mortality rate. CONCLUSIONS: Adrenal lesions measuring 4 cm or more in diameter are not a contraindication for LA neither in terms of cancer risk nor of conversion and morbidity rates, even if the operative time increases with increasing adrenal lesion diameter. Further prospective studies with a larger number of patients are required to draw definitive conclusions.

BACKGROUND: A difficulty score for laparoscopic adrenalectomy (LA) is lacking in the literature. A retrospective cohort study was designed to develop a preoperative "difficulty score" for LA. METHODS: A multicenter study was conducted involving four Italian tertiary centers for adrenal disease. The population was randomly divided into two subsets: training group and validation one. A multicenter study was undertaken, including 964 patients. Patient, adrenal lesion, surgeon's characteristics, and the type of procedure were studied as potential predictors of target events. The operative time (pOT), conversion rate (cLA), or both were used as indicators of the difficulty in three multivariate models. All models were developed in a training cohort (70% of the sample) and validated using 30% of patients. For all models, the ability to predict complicated postoperative course was reported describing the area under the curve (AUCs). Logistic regression, reporting odds ratio (OR) with p-value, was used. RESULTS: In model A, gender (OR 2.04, p = 0.001), BMI (OR 1.07, p = 0.002), previous surgery (OR 1.29, p = 0.048), site (OR 21.8, p < 0.001) and size of the lesion (OR 1.16, p = 0.002), cumulative sum of procedures (OR 0.99, p < 0.001), extended (OR 26.72, p < 0.001) or associated procedures (OR 4.32, p = 0.015) increased the pOT. In model B, ASA (OR 2.86, p = 0.001), lesion size (OR 1.20, p = 0.005), and extended resection (OR 8.85, p = 0.007) increased the cLA risk. Model C had similar results to model A. All scores obtained predicted the target events in validation cohort (OR 1.99, p < 0.001; OR 1.37, p = 0.007; OR 1.70, p < 0.001, score A, B, and C, respectively). The AUCs in predicting complications were 0.740, 0.686, and 0.763 for model A, B, and C, respectively. CONCLUSION: A difficulty score based on both pOT and cLA (Model C) was developed using 70% of the sample. The score was validated using a second cohort. Finally, the score was tested, and its results are able to predict a complicated postoperative course.

BACKGROUND: To evaluate the impact of laparoscopic sleeve gastrectomy (LSG) and gastric bypass (LGB) on gastroesophageal reflux disease (GERD). METHODS: GERD was evaluated by the Modified Italian Gastroesophageal reflux disease-Health-Related Quality of Life (MI-GERD-HRQL) questionnaire, pH-manometry, endoscopy, and Rx-esophagogram, before and 12 months after surgery. Based on these exams, patients without GERD underwent LSG, and patients with GERD underwent LGB. RESULTS: Thirteen and six patients underwent LSG and LGB, respectively. After LSG, the only statistically significant difference observed at pH-manometry was the median DeMeester score, from 5.7 to 22.7 (P = .0026). De novo GERD occurred in 6 patients (46.2%), with erosive esophagitis in one. The median MI-GERD-HRQL score improved from 3 to 0. Overall, nine patients underwent LGB, but three were lost to follow-up. Preoperative pH-manometry changed the surgical indication from LSG to LGB in 7 out of 9 patients (77.8%). Six patients who underwent LGB completed the study, and at pH-manometry, statistically significant differences were observed in the percentage of total acid exposure time, with the number of reflux episodes lasting >5 minutes and DeMeester score (P = .009). The median MI-GERD-HRQL score improved from 6.5 to 0. Statistically significant differences were not observed at endoscopy and Rx-esophagogram findings in both groups. CONCLUSIONS: LSG has a negative impact on GERD, even in patients without preoperative GERD. LGB confirmed to be the intervention of choice in patients with GERD. Preoperative pH-manometry may identify patients with silent GERD, to candidate them to LGB rather than LSG. pH-manometry should be used more liberally to establish the correct surgical indication on objective grounds.

BACKGROUND: Anastomotic leakage (AL) is one of the dreaded complications following surgery in the digestive tract. Near-infrared fluorescence (NIRF) imaging is a means to intraoperatively visualize anastomotic perfusion, facilitating fluorescence image-guided surgery (FIGS) with the purpose to reduce the incidence of AL. The aim of this study was to analyze the current practices and results of NIRF imaging of the anastomosis in digestive tract surgery through the EURO-FIGS registry. METHODS: Analysis of data prospectively collected by the registry members provided patient and procedural data along with the ICG dose, timing, and consequences of NIRF imaging. Among the included upper-GI, colorectal, and bariatric surgeries, subgroup analysis was performed to identify risk factors associated with complications. RESULTS: A total of 1240 patients were included in the study. The included patients, 74.8% of whom were operated on for cancer, originated from 8 European countries and 30 hospitals. A total of 54 surgeons performed the procedures. In 83.8% of cases, a pre-anastomotic ICG dose was administered, and in 60.1% of cases, a post-anastomotic ICG dose was administered. A significant difference (p < 0.001) was found in the ICG dose given in the four pathology groups registered (range: 0.013-0.89 mg/kg) and a significant (p < 0.001) negative correlation was found between the ICG dose and BMI. In 27.3% of the procedures, the choice of the anastomotic level was guided by means of NIRF imaging which means that in these cases NIRF imaging changed the level of anastomosis which was first decided based on visual findings in conventional white light imaging. In 98.7% of the procedures, the use of ICG partly or strongly provided a sense of confidence about the anastomosis. A total of 133 complications occurred, without any statistical significance in the incidence of complications in the anastomoses, whether they were ICG-guided or not. CONCLUSION: The EURO-FIGS registry provides an insight into the current clinical practice across Europe with respect to NIRF imaging of anastomotic perfusion during digestive tract surgery.

PURPOSE: Aim of this systematic review is to assess the changes in esophageal motility and acid exposure of the esophagus through esophageal manometry and 24-hours pH-monitoring before and after laparoscopic sleeve gastrectomy (LSG). METHODS: Articles in which all patients included underwent manometry and/or 24-hours pH-metry or both, before and after LSG, were included. The search was carried out in the PubMed, Embase, Cochrane, and Web of Science databases, revealing overall 13,769 articles. Of these, 9702 were eliminated because they have been found more than once between the searches. Of the remaining 4067 articles, further 4030 were excluded after screening the title and abstract because they did not meet the inclusion criteria. Thirty-seven articles were fully analyzed, and of these, 21 further articles were excluded, finally including 16 articles. RESULTS: Fourteen and twelve studies reported manometric and pH-metric data from 402 and 547 patients, respectively. At manometry, a decrease of the lower esophageal sphincter resting pressure after surgery was observed in six articles. At 24-hours pH-metry, a worsening of the DeMeester score and/or of the acid exposure time was observed in nine articles and the de novo gastroesophageal reflux disease (GERD) rate that ranged between 17.8 and 69%. A meta-analysis was not performed due to the heterogeneity of data. CONCLUSIONS: After LSG a worsening of GERD evaluated by instrumental exams was observed such as high prevalence of de novo GERD. However, to understand the clinical impact of LSG and the burden of GERD over time further long-term studies are necessary.

BACKGROUND & AIMS: Patients with non-alcoholic fatty liver disease (NAFLD) are at increased chance for cardiovascular events (CVEs). Severity of liver fibrosis is used to determine prognoses for patients with NAFLD, but little is known about the relationship between liver fibrosis and CVEs in the real world. METHODS: We analyzed data from the prospective observational progression of liver damage and cardiometabolic disorders in non-alcoholic fatty liver disease study, comprising 898 consecutive outpatients (mean age, 56.4 ± 12.7 years; 37.5% women) screened for liver steatosis by ultrasound according to Hamagughi criteria. Liver fibrosis was defined as FIB-4 score greater than 2.67 and NAFLD fibrosis score greater than 0.676. After enrolment, patients were interviewed by phone every 6 months and examined every 12 months in the outpatient clinic, and CVEs were recorded (fatal or nonfatal ischemic stroke and myocardial infarction, cardiac or peripheral revascularization, new-onset arterial fibrillation and cardiovascular death). The primary outcomes were incidence rate of CVEs in patients with vs without NAFLD and factors associated with CVEs in patients with NAFLD. RESULTS: Over a median follow-up time of 41.4 months (3044.4 patient-years), 58 CVEs (1.9%/year) were registered. The rate of CVEs was higher in patients with (n = 643, 2.1%/year) vs without NAFLD (n = 255, 1.0%/year) (P = .066). In multivariable Cox proportional regression analysis, NAFLD increased risk for CVEs (hazard ratio [HR], 2.41; 95% CI, 1.06-5.47; P = .036), after adjustment for metabolic syndrome. Among patients with NAFLD, male sex, previous CVEs, metabolic syndrome and FIB-4 scores greater than 2.67 (HR, 4.02; 95% CI, 1.21-13.38; P = .023) were independently associated with risk of incident CVEs. NFS scores greater than 0.676 were also independently associated with risk of incident CVEs (HR, 2.35; 95% CI, 1.05-5.27; P = .038). CONCLUSIONS: In an analysis of data from a study of patients screened for NAFLD and followed, individuals with NAFLD had more than a 2-fold increase in risk of CVEs, and those with liver fibrosis had a 4-fold increase in risk. In patients with NAFLD, liver fibrosis indexes were independently associated with risk of incident CVEs. ClinicalTrials.gov no:NCT04036357.

BACKGROUND: The aim is to evaluate safety and efficacy of near infra-red (NIR) indocyanine green (ICG) fluorescence structural imaging during laparoscopic cholecystectomy (LC) (Group A) and to compare perioperative data, including operative time, with a series of patients who underwent LC with routine traditional intraoperative cholangiography (IOC) (Group B). METHODS: Forty-four patients with acute or chronic cholecystitis underwent NIR-ICG fluorescent cholangiography during LC. ICG was administered intravenously at different time intervals or by direct gallbladder injection during surgery. Fluorescence intensity and anatomy identification were scored according to a visual analogue scale between 1 (least accurate) and 5 (most accurate). Group B patients (n = 44) were chosen from a prospectively maintained database of patients who underwent LC with routine IOC, matched for age, sex, body mass index, and diagnosis with group A patients. RESULTS: No adverse reactions were recorded. In group A, mean time between intravenous administration of ICG and surgery was 10.7 ± 8.2 (range 2-52) h. Administered doses ranged from 3.5 to 13.5 mg. Fluorescence was present in all cases, scoring ≥ 3 in 41 patients. Mean operative time was 86.9 ± 36.9 (30-180) min in group A and 117.9 ± 43.4 (40-220) min in group B (p = 0.0006). No conversion to open surgery nor bile duct injuries were observed in either group. CONCLUSIONS: LC with NIR-ICG fluorescent cholangiography is safe and effective for early recognition of anatomical landmarks, reducing operative time as compared to LC with IOC, even when residents were the main operator. NIR-ICG fluorescent cholangiography was effective in patients with acute cholecystitis and in the obese. Data collection into large registries on the results of NIR-ICG fluorescent cholangiography during LC should be encouraged to establish whether this technique might set a new safety standard for LC.

INTRODUCTION: Near-infrared fluorescence cholangiography (NIRF-C) is a popular application of fluorescence image-guided surgery (FIGS). NIRF-C requires near-infrared optimized laparoscopes and the injection of a fluorophore, most frequently Indocyanine Green (ICG), to highlight the biliary anatomy. It is investigated as a tool to increase safety during cholecystectomy. The European registry on FIGS (EURO-FIGS: www.euro-figs.eu ) aims to obtain a snapshot of the current practices of FIGS across Europe. Data on NIRF-C are presented. METHODS: EURO-FIGS is a secured online database which collects anonymized data on surgical procedures performed using FIGS. Data collected for NIRF-C include gender, age, Body Mass Index (BMI), pathology, NIR device, ICG dose, ICG timing of administration before intraoperative visualization, visualization (Y/N) of biliary structures such as the cystic duct (CD), the common bile duct (CBD), the CD-CBD junction, the common hepatic duct (CHD), Visualization scores, adverse reactions to ICG, operative time, and surgical complications. RESULTS: Fifteen surgeons (12 European surgical centers) uploaded 314 cases of NIRF-C during cholecystectomy (cholelithiasis n = 249, cholecystitis n = 58, polyps n = 7), using 4 different NIR devices. ICG doses (mg/kg) varied largely (mean 0.28 ± 0.17, median 0.3, range: 0.02-0.62). Similarly, injection-to-visualization timing (minutes) varied largely (mean 217 ± 357; median 57), ranging from 1 min (direct intragallbladder injection in 2 cases) to 3120 min (n = 2 cases). Visualization scores before dissection were significantly correlated, at univariate analysis, with ICG timing (all structures), ICG dose (CD-CBD), device (CD and CD-CBD), surgeon (CD and CD-CBD), and pathology (CD and CD-CBD). BMI was not correlated. At multivariate analysis, pathology and timing remained significant factors affecting the visualization scores of all three structures, whereas ICG dose remained correlated with HD visualization only. CONCLUSIONS: The EURO-FIGS registry has confirmed a wide disparity in ICG dose and timing in NIRF-C. EURO-FIGS can represent a valuable tool to promote and monitor FIGS-related educational and consensus activities in Europe.

BACKGROUND: The aim of this case-control study is to compare the surgical outcomes of laparoscopic adrenalectomy (LA) for lesions measuring ≥6 cm versus ≤5.9 cm in diameter. METHODS: Eighty-one patients with adrenal gland lesions ≥6 cm in diameter (intervention group) were identified. Patients were matched to 81 patients with adrenal gland ≤5.9 cm in diameter (control group) based on disease (Conn-Cushing syndrome, pheochromocytoma, primary or secondary adrenal cancer or other disease), lesion side (right, left), surgical technique (anterior transperitoneal approach for right and left LA or anterior transperitoneal submesocolic for left LA) and body mass index class (18-24.9, 25-29.9, 30-34.9, 35-39.9, ≥40 kg/m2). Surgical outcomes were compared between the intervention and control groups. RESULTS: Mean operative time was statistically significantly longer in the interventional arm (101.4 ± 52.4 vs. and 85 ± 31.6 min, p = 0.0174). Eight conversions were observed in the intervention group (9.8%) compared to four in the control group (4.9%) (p = 0.3690). Five (6.1%) and three (3.7%) postoperative complications were observed in the intervention and control groups, respectively (p = 0.7196). Mean postoperative hospital stay was 4.6 ± 2.4 and 4.1 ± 2.3 days in the intervention and control groups, respectively (p = 0.1957). CONCLUSIONS: Operative time was statistically significantly longer in adrenal gland lesions ≥6 cm in diameter (vs. ≤5.9 cm). Conversion and complication rates were also higher, but the difference was not statistically significant. Based on the present data, adrenal gland lesions ≥6 cm in diameter are not an absolute contraindication to the laparoscopic approach.

BACKGROUND: The aim of the present study is to report and to compare the results of three different laparoscopic transperitoneal surgical approaches [lateral transperitoneal (LT), anterior transperitoneal (AT) and anterior transperitoneal submesocolic (ATS)] for the treatment of Conn's and Cushing's syndrome from left adrenal disease. METHODS: This study is a retrospective analysis of prospectively collected data. From 1994 to 2017, 535 laparoscopic adrenalectomies (LA) were performed. One hundred and sixty-four patients with Conn's or Cushing's syndrome underwent left LA. Patients were divided in three groups based on the approach: LT (Group A), AT (Group B) and ATS (Group C). RESULTS: The diagnosis was Conn's and Cushing's syndrome in 99 and 65 patients, respectively. LT was used in 13 cases, AT in 55 and ATS in 96. No significant differences in patient's gender, age and BMI were observed. Mean operative time was 117.6 ± 33.7, 107.6 ± 40.3 and 96.2 ± 47.5 min for Groups A, B and C, respectively. Conversion to open surgery was observed in 4 Group C patients (4.1%). Morbidity occurred in 2 Group B (2%) and in 5 Group C patients (5.2%). CONCLUSIONS: In case of Conn's or Cushing's syndrome, left LA with ATS approach is equally safe and effective as compared to the LT and AT approaches. Early control of the adrenal vein with minimal gland manipulation and limited surgical dissection are the major advantages of the submesocolic approach. Even if statistically significant differences are not observed, postoperative results are the same as those reported in the literature with other approaches.

BACKGROUND: The aim of this study is to evaluate the feasibility, safety, advantages and surgical outcomes of laparoscopic bilateral adrenalectomy (LBA) by an anterior transperitoneal approach. METHODS: From 1994 to 2018, 552 patients underwent laparoscopic adrenalectomy, unilateral in 531 and bilateral in 21 patients (9 females and 12 males). All patients who underwent LBA were approached via a transperitoneal anterior route and form our study population. Indications included: Cushing's disease (n = 11), pheochromocytoma (n = 6), Conn's disease (n = 3) and adrenal cysts (n = 1). RESULTS: Mean operative time was 195 ± 86.2 min (range 55-360 min). Conversion was necessary in one case for bleeding. Three patients underwent concurrent laparoscopic cholecystectomy with laparoscopic common bile duct exploration and ductal stone extraction in one. Three postoperative complications occurred in one patient each: subhepatic fluid collection, intestinal ileus and pleural effusion. Mean hospital stay was 6.1 ± 4.7 days (range 2-18 days). CONCLUSIONS: In our experience, transperitoneal anterior LBA was feasible and safe. Based on our results, we believe that this approach leads to prompt recognition of anatomical landmarks with early division of the main adrenal vein prior to any gland manipulation, with a low risk of bleeding and without the need to change patient position. Unlike the lateral approach, there is no need to mobilize the spleno-pancreatic complex on the left or the liver on the right. The ability to perform associated intraperitoneal procedures, if required, is an added benefit.

Introduction: The combination of Cushing's syndrome and obesity, one of the most common manifestations of the syndrome itself, may be associated with the worsening of post-operative outcomes in case of laparoscopic adrenalectomy. This study focused on the laparoscopic treatment of Cushing's syndrome with the purpose to identify any relevant difference between morbidly obese, mildly obese and non-obese patients.Material and methods: Patients were retrospectively divided into three groups according to their Body Mass Index (BMI). Demographic characteristics, operative and post-operative data were collected. Data about different hemostatic devices were also collected and compared. Differences were analyzed with the Fisher's exact test for categorical variables, and the Mann-Whitney test for continuous variables.Results: No differences were found in operative time (101.5 ± 50.9 min; p = .919), conversion rate (2.6%; p = .655) or length of stay (4.3 ± 2.9 days; p = .886). Complication rate was 3% (p = .32), without any mortality. 95% of patients showed a complete resolution of hypercotisolyism-related symptoms, and a mean BMI reduction of 5 ± 3.2 kg/m2 (follow up = 6.3 ± 4.2 years). Conclusions: Laparoscopic adrenalectomy is safe and feasible in obese patients affected with Cushing's disease and it can lead to the resolution of the related symptoms.

BACKGROUND: Laparoscopic common bile duct exploration (LCBDE) during laparoscopic cholecystectomy (LC) is as effective as two-stage endo-laparoscopic treatment, but with shorter hospital stay, lower cost and recurrent stone rate. Aim of this paper was to report the authors' experience with LCBDE during LC. METHODS: A retrospective analysis of patients who underwent LCBDE for ductal stones was performed. Recurrent stones were defined as CBD stones detected beyond 6 months from the procedure. Postoperative biliary stricture was defined as a symptomatic reduction of CBD diameter. RESULTS: Out of 3444 patients who underwent LC, 384 (11%) had CBD stones treated by trans-cystic duct exploration [214 (6%) patients, TCD-CBDE] or choledochotomy [170 (5%) patients, C-CBDE]. For TCD-CBDE and C-CBDE, mean operative time was 127 ± 69 and 191 ± 74 min, respectively. Major morbidity rate was 3% (n = 6) in TCD-CBDE and 6% (n = 11) in C-CBDE. The incidence of residual stones was 5% (n = 20) and complete ductal clearance rate was 95% (n = 364). After long-term follow-up (mean 189 ± 105 months) the recurrent stone rate was 2%. DISCUSSION: In expert centers, LCBDE during LC is safe and effective with low short and long term morbidity rates.

BACKGROUND: In selected patients with N0 rectal cancer, endoluminal loco-regional resection (ELRR) by transanal endoscopic microsurgery (TEM) may be an alternative treatment option to laparoscopic total mesorectal excision (LTME). Aim of this study is to evaluate the short- and medium-term quality of life (QoL) from a retrospective analysis of prospectively collected data in patients with iT2-iT3 N0-N+ rectal cancer, who underwent ELRR by TEM or LTME after neoadjuvant radio-chemotherapy (n-RCT). METHODS: Thirty patients with iT2-iT3 rectal cancer who underwent ELRR by TEM (n = 15) or LTME (n = 15) were enrolled in this study. The choice for one operation or the other was made on the basis of predefined criteria. QoL was evaluated by EORTC QLQ-C30 and QLQ-CR38 questionnaires at admission, after n-RCT and 1, 6, and 12 months after surgery. RESULTS: No statistically significant differences in QoL evaluation were observed between the two groups, both at admission and after n-RCT. At 1 month after surgery, significantly better results in the ELRR group were observed by QLQ-C30 in: Nausea/Vomiting (p = 0.05), Appetite Loss (p = 0.003), Constipation (p = 0.05), and by QLQ-CR38 in: Body Image (p = 0.05), Sexual Functioning (p = 0.03), Future Perspective (p = 0.05) and Weight Loss (p = 0.036). At 6 months after surgery, a statistically significant worse impact after LTME was observed by QLQ-C30 in: Global Health Status (p = 0.05), Emotional Functioning (p = 0.021), Dyspnea (p = 0.008), Insomnia (p = 0.012), Appetite Loss (p = 0.014) and by QLQ-CR38 in Body Image (p = 0.05) and Defecation Problems (p = 0.001). At 1 year, the two groups were homogenous as assessed by QLQ-C30, whereas the QLQ-CR38 still showed better results of ELRR versus LTME in Body Image (p = 0.006), Defecation Problems (p = 0.01), and Weight Loss (p = 0.005). CONCLUSIONS: Based on the present series, in selected patients, earlier restoration of patients' functions is observed after ELRR by TEM than after LTME.
