Laparoscopic cholecystectomy (LC) is the standard technique for treatment of gallbladder disease. In case of acute cholecystitis we can identify preoperative factors associated with an increased risk of conversion and intraoperative complications. The aim of our study was to detect preoperative laboratory and radiological findings predictive of difficult LC with potential advantages for both the surgeons and patients in terms of options for management. We designed a retrospective case–control study to compare preoperative predictive factors of difficult LC in patients treated in emergency setting between January 2015 and December 2019. We included in the difficult LC group the surgeries with operative time > 2 h, need for conversion to open, significant bleeding and/or use of synthetic hemostats, vascular and/or biliary injuries and additional operative procedures. We collected 86 patients with inclusion criteria and difficult LC. In the control group, we selected 86 patients with inclusion criteria, but with no operative signs of difficult LC. The analysis of the collected data showed that there was a statistically significant association between WBC count and fibrinogen level and difficult LC. No association were seen with ALP, ALT and bilirubin values. Regarding radiological findings significant differences were noted among the two groups for irregular or absent wall, pericholecystic fluid, fat hyperdensity, thickening of wall > 4 mm and hydrops. The preoperative identification of difficult laparoscopic cholecystectomy provides an important advantage not only for the surgeon who has to perform the surgery, but also for the organization of the operating block and technical resources. In patients with clinical and laboratory parameters of acute cholecystitis, therefore, it would be advisable to carry out a preoperative abdominal CT scan with evaluation of features that can be easily assessed also by the surgeon.

The aim of this prospective clinical study is compare short-term outcome of laparoscopic right hemicolectomy using the Complete Mesocolic Excision (CME group) with patients who underwent conventional right-sided colonic resection (NCME group). Summary Background Data: Although CME with central vascular ligation in laparoscopic righthemicolectomy is associated with a significant decrease in local recurrence rates and improvements in cancerrelated 5-year survival, there may be additional risks associated with this technique because of increased surgical complications. As a result, there is controversy surrounding its use. Methods:In this randomized controlled trial, several primary endpoints (operative time, intraoperative blood loss, other complications, conversion rate, and anastomotic leak) and secondary endpoints (overall postoperative complications) were evaluated. In addition, we evaluated histopathologic data, including specimen length and the number of lymph nodes harvested, as objective signs of the quality of CME, related to oncological outcomes. Results:The CME group had a significantly longer mean operative time than the NCME group (216.3 min versus 191.5 min, p=0.005). However, the CME group had a higher number of lymph nodes (23.8 versus 16.6; p<0.001) and larger surgical specimens (34.3 cm versus 29.3 cm; p=0002). No differences were reported with respect to intraoperative blood loss, conversion rate, leakage, or other postoperative complications. Conclusions:In this study laparoscopic CME were a safe and feasible technique with improvement in lymph nodes harvesting and length of surgical specimens with no increase of surgical intraoperative and postoperative complications.

Highlights Abdominal pain due to acute appendicitis in one of the most causes of access to Emergency Room requiring surgical consult and treatment. The occurrence of anatomical anomalies should be considered especially when clinical and imaging features are misleading. In these cases laparoscopic surgery can be a safe tool in order to confirm uncertain diagnosis. We report a case of acute appendicitis in a 23-year-old Caucasian men with situs viscerum inversus detected on radiological investigation. Laparoscopic approach was used to confirm the diagnosis and to perform appendectomy. Trocars placement was tailored for this peculiar case. Situs viscerum inversus and midgut malrotation should be taken into consideration in patients with findings of the physical examination suspicious for left-sided acute appendicitis.

Highlights Melanoma is one of the most aggressive and one of the fastest growing types of cancer. The gallbladder envolvement from a metastatic cutaneous malignant melanoma is a highly uncommon finding, usually associated with diffuse metastatic disease and observed during autopsy. We report a case of a 35-years old Caucasian woman with isolated metastasis of gallbladder form cutaneous primary malignant melanoma underwent to laparoscopic cholecystectomy. Malignant cutaneous melanoma is a skin cancer characterized by the highest mortality. Isolated metastasis of gallbladder are barely described and mostly present in a widespread metastatic disease. Surgical treatment is indicated considering the extension of the disease and the clinical status of the patient.

IntroductionKlippel–Trenaunay syndrome (KTS) is a rare vascular congenital disorder characterized by the classical triad of port-wine stains, abnormal growth of soft tissues and bones, and vascular malformations. The involvement of the genitourinary tract and of the uterus in particular is extremely infrequent but relevant for possible consequences.MethodsWe performed an extensive review of the literature using the Pubmed, Scopus and ISI web of knowledge database to identify all cases of KTS with uterine involvement. The search was done using the MeSH term “Klippel–Trenaunay syndrome” AND “uterine” OR “uterus.” We considered publications only in the English language with no limits of time. We selected a total of 11 records of KTS with uterine involvement, including those affecting pregnant women.ResultsKlippel–Trenaunay syndrome was described for the first time in the year 1900 in two patients with hemangiomatous lesions of the skin associated with varicose veins and asymmetric soft tissue and bone hypertrophy. Uterine involvement is a rare condition and can cause severe menorrhagia. Diagnosis is based on physical signs and symptoms. CT scans and MRI are first-choice test procedures to evaluate both the extension of the lesion and the infiltration of deeper tissues before treatment. The management of Klippel–Trenaunay syndrome should be personalized using careful diagnosis, prevention and treatment of complications.ConclusionKlippel–Trenaunay syndrome is a rare vascular malformation with a wide variability of manifestations. There are no univocal and clear guidelines that suggest the most adequate monitoring of the possible complications of the disease. Treatment is generally conservative, but in case of recurrent bleeding, surgery may be needed.
