    The use of minimally invasive surgery in colon cancers is becoming widespread and developing day by day Laparoscopic right hemicolectomy (LRHC) with complete mesocolic excision is gradually becoming the standard oncological surgical principle for right hemicolectomy. The aim of our study was to evaluate the safety and efficacy of laparoscopic right hemicolectomy in a small-volume center. METHODS: Clinical outcomes were analyzed in a study comparing laparoscopic right hemicolectomy with conventional right hemicolectomy. By standardizing laparoscopic right hemicolectomy in our center, data on patient characteristics, surgical details, tumor, lymph node, and metastasis stage (TNM), postoperative recovery, and survival were retrieved and analyzed from retrospective databases. RESULTS: Patients underwent open (n. 63) and laparoscopic (n. 51) right hemicolectomies in our units. In the laparoscopic group, the rate of conversion to open was 5.8%, and there was no mortality for 30 days. In the open group, the first-month mortality was 6.3%, and the rate of complications was 15.9%. The mean age of the patients in the laparoscopic group (65.7 +/- 13.46) was statistically significantly higher than that of the open group 60.49 +/- 12.67) (p=0.042). Operation time was 147.53 +/- 57 minutes in the laparoscopic group and 132.84 +/- 34 minutes in the open batch, and there was no statistically significant difference between them. Significant correlations were found between stage and cancer subgroup information (p=0.001). Adenocarcinoma (42%) and mucinous (43.8%) type cancers were found more frequently in patients with stage III, while signet ring cancers were more common (100%) in stage IV patients. CONCLUSIONS: LRHC and laparoscopic conventional right hemicolectomy offered similar oncologic outcomes for right colon cancers in small volume centers. LRHC can be performed safely, and sufficient laparoscopic experience is essential for it to be considered the gold standard procedure. With an improved standard technique and systematic learning method, patient safety and surgical results can be achieved as successfully as in the open surgical approach.

    Treatment of Hepatic Hydatid Disease: Role of Surgery, ERCP, and Percutaneous Drainage: A Retrospective Study

    Introduction: Failure to follow the World Health Organization's Informal Working Group on Echinococcosis guidance or having limited experience in the management of cystic echinococcosis (CE) in endemic or nonendemic areas of the world may lead to risky unnecessary procedures. Materials and Methods: Medical records of all patients undergoing surgery for hepatic hydatid disease at the gastroenterologic surgery and general surgery departments of our hospital between December 2014 and October 2019 were collected and reviewed retrospectively. Demographic characteristics, the size and number of the cysts preoperative liver function tests, surgical treatment, endoscopic retrograde cholangiopancreatography (ERCP), percutaneous drainage (PD), morbidity, and treatment outcomes were reviewed. Results: Of 122 patients included in the study, 77 (63, 1%) were female and 45 (36, 9%) were male individuals and their mean age was 44.95 years. CE1 was identified in 13 patients (10.6%) CE2 in 66 patients (54.1%), CE3a in 7 patients (5.8%), CE3b in 28 patients (22.9%), and CE4 in 8 patients (6.6%). Twenty patients (16.4%) with a cystobiliary fistula in the liver, obstructive jaundice, and postoperative bile leak underwent ERCP. PD was performed in patients with fluid in the hepatic hydatid cyst pouch, increased pouch size because of bile collection, and clinical symptoms postoperatively. Patients presenting with persistent bile leak despite PD underwent ERCP and were treated with endoscopic sphincterotomy and stent placement. Patients with PD were followed by keeping the percutaneous drain open and closed for a while to create pressure difference in the cyst pouch after ERCP. The percutaneous drain was removed in the next 14 to 21 days after checking the pouch size, whereas the common bile duct stents were removed 2 months later after performing a follow-up cholangiography. Conclusions: ERCP should be the primary method for the diagnosis and treatment for hepatic hydatid cysts ruptured into the ducts. In some cases, high-flow hydatid cysts with rupture into the bile ducts or persistent biliary fistulas can be treated with ERCP and endoscopic sphincterotomy, biliary stent, PD, and nasobiliary drainage without the need for surgical intervention.
