Item Current status of laparoscopic surgery usage in Turkiye: A middle-income country(2022) Esmer, Ahmet Cem; Colak, Tahsin; Edizsoy, Akay; Tazeoglu, Deniz; Karaca, Ahmet Serdar; 36875273Objective: This study aimed to determine the usage status of laparoscopic procedures in general surgical practice in Turkiye, which is a sample of middle-income countries. Material and Methods: The questionnaire was sent to general surgeons, gastrointestinal surgeons, and surgical oncologists who have completed their residency training and are actively working in university, public or private hospitals. Demographic data, laparoscopy training and the period of education, the rate of laparoscopy use, the type and volume of laparoscopic surgical procedures, their views on the advantages and disadvantages of laparoscopic surgery, and the reasons for preferring laparoscopy were determined with a 30-item questionnaire. Results: Two hundred and forty-four questionnaires from 55 different cities of Turkiye were evaluated. The responders were mainly males, younger surgeons (F/M=11.1/88.9 % and 30-39 y/o), and graduated from the university hospital residence program (56.6%). Laparoscopic training was frequently taken during residency (77.5%) in the younger age group, while the elderly participants mostly received additional training after specialization (91.7%). Laparoscopic surgery was mostly not available in public hospitals for advanced procedures (p< 0.0001) but was available for cholecystectomy and appendectomy operations (p=NS). However, participants working in university hospitals mostly stated that the laparoscopic approach was the first choice for advanced procedures. Conclusion: The results of this study showed that the surgeons working in MICs spent strong effort to use laparoscopy in daily practice, especially in university and high-volume hospitals. However, inappropriate education, cost of laparoscopic equipment, healthcare policies, and some cultural and social barriers might have negatively impacted the widespread use of laparoscopic surgery and its usage in daily practice in MICs such as Turkiye.Item Polymeric Clips for Stump Closure in Laparoscopic Appendectomy(2017) Parlakgumus, Alper; Ezer, Ali; 0000-0002-3834-9924; 29056133; AAJ-8558-2021Many different techniques are used to perform laparoscopic appendectomy in terms of locations of trocars and closure of the appendiceal stump. They include mechanical endostaplers, endoligature, metal clips, bipolar endocoagulation, polymeric clips and intracorporeal sutures. The method of choice for appendiceal stump closure should be inexpensive and easy to perform. Non-absorbable polymer clips is an acceptable option for this purpose. Polymeric clips provide considerable cost savings as compared with endoscopic staplers, and are easy to apply in comparison to suture ligature techniques. In this study, we aimed to investigate outcomes of appendectomy carried out by using polymeric clips in 123 patients without any intraabdominal collection of pus or abscess. As such, the authors found polymeric clips to be safe, cheap and effective for stump closure in laparoscopic appendectomy.Item Single-port Hysterectomy: Robotic Versus Laparoscopic(2018) Gungor, Mete; Kahraman, Korhan; Dursun, Polat; Ozbasli, Esra; Genim, Canan; 28429119This study evaluated the feasibility and safety of robotic single port hysterectomy and laparoscopic single port hysterectomy, and to compare the perioperative parameters of the two systems. Twenty patients underwent robotic single port hysterectomy and 25 patients underwent laparoscopic single port hysterectomy. All hysterectomies were successfully performed via a single port and there were no conversions to conventional multi-port laparoscopy, multi-port robotic, open surgery, or vaginal surgery. The median operative time and hysterectomy time in robotic and laparoscopic groups were 90 vs. 90 min (P 0.74), 57.5 vs. 60 min (P 0.17), respectively. The median estimated blood loss was 40 ml in the robotic group and 50 ml in the laparoscopic group (P 0.77). No operative and post-operative complications were observed in the two groups. The median time to discharge from the hospital was one day for both techniques (P 0.17). Robotic and laparoscopic single port systems are feasible and safe for hysterectomy operation in terms of operative time, conversion to laparotomy or multiport laparoscopy/robotic rates, complication rates, and postoperative results in the hands of experienced surgeons. The possible benefits of robotic single port surgery compared with conventional laparoscopy should be evaluated in further randomized controlled studies.Item Importance of Laparoscopy in Predicting Complete Cytoreduction at Advanced Stage Ovarian Cancer(2022) Durdag, Gulsen Dogan; Alemdaroglu, Songul; Baran, Safak Yilmaz; Serbetcioglu, Gonca Coban; Ozmete, Ozlem; Ezer, Ali; Celik, Husnu; https://orcid.org/0000-0003-4335-6659Purpose Laparoscopy has been used in evaluation of ovarian cancer to assess the extent and surgical resectability of the disease, and to avoid futile laparotomy, where primary cytoreduction is not suitable. Aim of this study is to investigate the contribution of laparoscopy in predicting 'no gross residue' in advanced stage ovarian cancer. Methods Data of advanced stage ovarian cancer patients, who underwent diagnostic laparoscopy for prediction of complete cytoreduction due to an alternative model, are analyzed retrospectively. Accordingly, in the absence of obvious mesenteric retraction or extensive tumoral implants on small intestine in laparoscopic assessment, cases were deemed surgically resectable, and the operation was continued with laparotomy to achieve complete cytoreduction. Clinical features of the patients, surgical details, complete and optimal cytoreduction rates, and perioperative complications were evaluated. Results Out of 243 patients with advanced stage ovarian/tubal/peritoneal cancer, laparoscopy was performed at 93 patients, 77 of whom underwent primary cytoreduction subsequently. Complete cytoreduction (no gross residue) and optimal cytoreduction (< 1 cm residual tumor) rates were 75.3 and 100%, respectively. None of the patients had suboptimal surgery. Morbidity and mortality rates were acceptable. Conclusion Laparoscopic evaluation prior to cytoreductive surgery can highly contribute to prediction of complete or optimal cytoreduction in suitable patients. However, experience and skills of the surgeon, as well as technical equipment of the center, may affect surgery; therefore, the model to predict residual tumor should be individualized according to the set up and the surgical team of each center.Item Laparoscopic para-aortic lymphadenectomy: Technique and surgical outcomes(2021) Durda, Gulsen Dogan; Alemdaroglu, Songul; Baran, Safak Yilmaz; Yaginc, Didem Alkas; Simsek, Seda Yuksel; Celik, Husnu; 0000-0003-4335-6659; 0000-0001-5874-7324; 0000-0001-8309-3537; 0000-0003-1185-9227; 32961327; AAI-8400-2021; AAK-2461-2021; AAL-1923-2021Objective: Pelvic and para-aortic lymph node dissection is an important part of staging surgery. Aim of this study is to evaluate perioperative outcomes of patients, who underwent laparoscopic para-aortic lymphadenectomy for gynecological cancer in a single center over a period of 7 years, based on body mass index (BMI), and to present the surgical technique in steps. Methods: Data of patients who underwent para-aortic lymphadenectomy at gynecological oncology department of a tertiary center in between March 2013 and July 2020 were analyzed retrospectively. Patients were evaluated in two groups according to their BMI (< 30 kg/m(2) as non-obese and >= 30 kg/m(2) as obese groups). Surgical technique is described in steps. Perioperative outcomes of the two groups were evaluated. Results: A total of 230 patients were included in the study. BMI was >= 30 at 58.46 % of the patients. Perioperative features were not significantly affected by the patient's BMI with the presented surgical technique, however, collected para-aortic lymph node numbers were higher in the group with BMI <30, though sufficient number of lymph nodes were achieved in both groups. Conclusion: Although some technical difficulties may be encountered, laparoscopic para-aortic lymphadenectomy is feasable in gynecologic oncological surgery independent of BMI. However, surgical experience is important. (C) 2020 Elsevier Masson SAS.

We report our experience with gallbladder cancer that was incidentally diagnosed during or after laparoscopic cholecystectomy performed for gallstone disease. Methods: This study included all laparoscopic cholecystectomies due to gallstone disease undertaken from January 2010 to April 2015. Exclusion criteria were suspicion of malignancy and/or existence of gallbladder polyps detected with ultrasonography preoperatively. Patients with incidentally diagnosed gallbladder cancer were recorded, and the clinical and demographic characteristics of these patients were reviewed. Results: Of 6,114 patients in whom laparoscopic cholecystectomy was attempted, 5.948 were included in this study. Incidental gallbladder cancer was found in thirty-six patients, with a mean age of 64.08 years. The histological tumor stages were adenocarcinoma in situ in seven patient, pT1b in nine patient, pT2 in eleven patient, and pT3 in nine patients. Sixteen patients who underwent laparoscopic cholecystectomy alone underwent no additional surgery because of the low stage of the tumors. The twenty remaining patients, whose laparoscopic cholecystectomies were converted to open surgeries, underwent cholecystectomy, excision of the liver bed and lymph node dissection. The overall median survival time was 28 months. Conclusions: The incidence of incidental gallbladder cancer has been reported to vary, up to 2.85%. In this single-center study, the rate of incidental gallbladder cancer was found to be 0.60%. Female gender and advanced age are demographic risk factors for gallbladder carcinoma. Although gallbladder cancer is well known for its poor prognosis, tumors that are incidentally diagnosed are often found at an early stage and have a better prognosis.Item Surgical and interventional management of complications caused by acute pancreatitis(2014) Karakayali, Feza Y.; 25309073Acute pancreatitis is one of the most common gastrointestinal disorders worldwide. It requires acute hospitalization, with a reported annual incidence of 13 to 45 cases per 100000 persons. In severe cases there is persistent organ failure and a mortality rate of 15% to 30%, whereas mortality of mild pancreatitis is only 0% to 1%. Treatment principles of necrotizing pancreatitis and the role of surgery are still controversial. Despite surgery being effective for infected pancreatic necrosis, it carries the risk of long-term endocrine and exocrine deficiency and a morbidity and mortality rate of between 10% to 40%. Considering high morbidity and mortality rates of operative necrosectomy, minimally invasive strategies are being explored by gastrointestinal surgeons, radiologists, and gastroenterologists. Since 1999, several other minimally invasive surgical, endoscopic, and radiologic approaches to drain and debride pancreatic necrosis have been described. In patients who do not improve after technically adequate drainage, necrosectomy should be performed. When minimal invasive management is unsuccessful or necrosis has spread to locations not accessible by endoscopy, open abdominal surgery is recommended. Additionally, surgery is recognized as a major determinant of outcomes for acute pancreatitis, and there is general agreement that patients should undergo surgery in the late phase of the disease. It is important to consider multidisciplinary management, considering the clinical situation and the comorbidity of the patient, as well as the surgeons experience.

Material and Method: Prospective case controlled study. Data obtained from 172 laparoscopic procedures performed in Baskent University Alanya hospital gynecology clinic were collected between April 2012 and March 2014. Results: Difference in abdominal wall elevation measurements with force applied during primary trocar entry ranged from 1cm to 3cm (mean: 2.13 +/- 1cm) when elevated manually and 0.5cm to 3cm (mean: 0.89 +/- 0.8cm) with the towel clips. The difference was statistically significant (p<0.05). Discussion: Laparoscopic surgery or minimally invasive surgery in general will undoubtedly dominate all fields of medicine in the near future, therefore it would be mandatory for almost every surgical branch to provide adequate training and skills for the operator in the both pre and post graduation period.Item Effects of volume-controlled equal ratio ventilation with recruitment maneuver and positive end-expiratory pressure in laparoscopic sleeve gastrectomy: a prospective, randomized, controlled trial(2018) Tuncali, Bahattin; Erol, Varhk; Zeyneoglu, Pinar; 30119152Background/aim: We compared the effects of volume-controlled equal ratio ventilation (VC-ERV) and volume-controlled conventional ratio ventilation (VC-CRV) on oxygenation, ventilation, respiratory mechanics, and hemodynamic status during mechanical ventilation with recruitment maneuver (RM) and positive end-expiratory pressure (PEEP) in patients undergoing laparoscopic sleeve gastrectomy. Materials and methods: A total of 111 patients scheduled for laparoscopic sleeve gastrectomy were randomized to ventilation with inspiratory to expiratory ratio of 1:1 (Group VC-ERV) or 1:2 (Group VC-CRV) following tracheal intubation. RM (40 cmH2O, 15 s) and PEEP (10 cmH2O) were administered to all patients. Arterial blood gas samples were taken and peak airway pressure (Ppeak), mean airway pressure (Pmean), dynamic compliance (Cdyn), mean arterial pressure, heart rate, SpO2, and EtCO2 were recorded at 4 time points. Postoperative respiratory complications were recorded. Results: Oxygenation, ventilation, Pmean levels, and hemodynamic variables were similar in both groups. VC-ERV significantly decreased Ppeak and increased Cdyn compared to VC-CRV at all time points of the operation (P < 0.05). No pulmonary complication was observed in any patients. Condusion: VC-ERV provides significantly lower Ppeak and higher Cdyn with similar oxygenation, ventilation, hemodynamic parameters, and Pmean levels when compared to VC-CRV during mechanical ventilation with RM and PEEP in laparoscopic sleeve gastrectomy.
