Publication Open Access Comparison of Laparoscopic and Conventional Cystotomy/Partial Cystectomy in Treatment of Liver Hydatidosis(2019-01-01) Bektasoglu, HÜSEYİN KAZIM; HASBAHCECI, Mustafa; Taşçı, Yunus; Aydogdu, Ibrahim; MALYA, FATMA ÜMİT; Kunduz, ENVER; Dolay, KEMAL; BEKTAŞOĞLU, HÜSEYİN KAZIM; AYDOĞDU, İBRAHİM; MALYA, FATMA ÜMİT; KUNDUZ, ENVER; DOLAY, KEMALIntroduction. Hydatidosis is a zoonotic infection and treatment is mandatory to avoid complications. Surgery remains the frst choice in the treatment especially for CE2-CE3b cysts. Open or laparoscopic approaches are available. However, comparative studies are limited. Materials and Methods. Data of patients who underwent cystotomy/partial cystectomy for liver hydatidosis between January 2012 and September 2016 (n=77) were evaluated retrospectively. Recurrent cases and the patients with previous hepatobiliary surgery were excluded. 23 patients were operated upon laparoscopically and named as Group 1. 48 patients operated conventionally named as Group 2. Demographics, cyst characteristics, operative time, length of hospital stay, recurrences, and surgery related complications were evaluated. Results. Groups were similar in terms of demographics, cyst characteristics, and operative time. Te length of hospital stay was 3.4 days in Group 1 and 4.7 days in Group 2 (p=0,007). Te mean follow-up period was 17.8 months and 21.7 months, respectively (p=0.170). Overall complication rates were similar in two groups (p=0.764). Tree conversion cases occurred (13%). One mortality was seen in Group 2. Four recurrences occurred in each group (17% versus 8.3%, respectively) (p=0.258). Conclusions. Laparoscopy is a safe and feasible approach for surgical treatment of liver hydatidosis. Recurrence may be prevented by selection of appropriate cases in which exposure of cysts does not pose an intraoperative difcultyPublication Open Access Nonclosure of the Peritoneum during Appendectomy May Cause Less Postoperative Pain: A Randomized, Double-Blind Study(2019-01-01) BEKTAŞOĞLU, HÜSEYİN KAZIM; Hasbahceci, Mustafa; YIĞMAN, SAMET; YARDIMCI, ERKAN; KUNDUZ, ENVER; MALYA, FATMA ÜMİT; BEKTAŞOĞLU, HÜSEYİN KAZIM; YIĞMAN, SAMET; YARDIMCI, ERKAN; KUNDUZ, ENVER; MALYA, FATMA ÜMİTObjective: We aim to evaluate the effect of peritoneal closure on postoperative pain and life quality associated with open appendectomy operations. Methods: This is a single-center, prospective, randomized, and double-blinded study. Here, 18-65-year-old patients who underwent open appendectomy for acute appendicitis were included. Demographic data of the patients, operation time, length of hospital stay, pain scores using a 10 cm visual analogue scale (VAS) on the first postoperative day, quality of life assessment using the EuroQol-5D-5L questionnaire on postoperative 10th day, deep wound dehiscence, bowel obstruction, and mortality data were recorded. Results: In total, 112 patients were included in the study. The demographic data showed no significant difference between the groups. The median VAS score was lower in the group with open peritoneum, but this difference was not statistically significant (3 vs. 4, p=0.134). The duration of surgery was significantly shorter in the peritoneal nonclosure group (31.0 ± 15.1 vs. 38.5 ± 17.5 minutes, p=0.016). Overall complication rates and life quality test (EuroQol-5D-5L) results were similar between groups. Conclusion: Nonclosure of the peritoneum seems to shorten the duration of surgery without increasing complications during open appendectomy. Postoperative pain and life quality measures were not affected by nonclosure of the peritoneum. This trial is registered with NCT02803463.Publication Open Access Laparoscopic surgery in distal pancreatic tumors(2017-12-01) Malya, FATMA ÜMİT; Bektaşoğlu, HÜSEYİN KAZIM; HASBAHCECI, Mustafa; Taşçı, Yunus; Kunduz, ENVER; Karatepe, Oguzhan; Dolay, KEMAL; MALYA, FATMA ÜMİT; BEKTAŞOĞLU, HÜSEYİN KAZIM; KUNDUZ, ENVER; DOLAY, KEMALObjective: Laparoscopic distal pancreatectomy is increasingly being used in the surgical treatment of corpus and distal pancreatic tumors. In this study, patients who underwent laparoscopic or open distal pancreatectomy for benign or malignant causes were evaluated in terms of tumor characteristics and perioperative outcomes. Material and Methods: We retrospectively reviewed data from a total of 27 distal pancreatectomy cases performed for benign or malignant causes in the General Surgery Department between January 2013 and December 2015. Groups were compared according to the demographic characteristics of patients, operation type (laparoscopic or open, with splenectomy or spleen preservation), operation time, surgical site infection (superficial, deep wound infection, or intra-abdominal abscess), pancreatic fistula development, and histopathological examination results. Results: Both groups were similar in terms of age, sex, and body mass index (p=0.42). Tumor diameter was similar (p=0.18). The total number of resected lymph nodes was similar in both groups (p=0.6). Pancreatic fistula developed in one patient in each group. Mean hospital stay duration and the amount of intraoperative bleeding were similar in both groups. The laparoscopy group had a markedly lower overall morbidity rate (p=0.08). There was no mortality observed in the study subjects. Conclusion: Laparoscopic distal pancreatectomy can be safely performed as a minimally invasive procedure in experienced centers and in selected cases without increasing perioperative complication rates, particularly in benign cases. Although oncological outcomes are acceptable for malignant cases, future prospective controlled studies are necessary for more reliable evaluation.

The perineal herniation is one of the complications of APR surgery. In this report, we aim to demonstrate a rare case of small bowel evisceration and strangulation secondary to the transvaginal herniation evolved in the late stage after perineal hernia repair following laparoscopic APR.Publication Metadata only Evaluation of local hemostatic effect of microporous polysaccharide hemospheres products in thyroid surgery: a prospective randomized controlled study(2019-03-01) KUNDUZ, ENVER; Ayşan, MUSTAFA ERHAN; Idiz, Ufuk Oğuz; ERSOY, YELİZ EMİNE; Bektaşoğlu, HÜSEYİN KAZIM; KUNDUZ, ENVER; AYŞAN, MUSTAFA ERHAN; ERSOY, YELIZ EMINE; BEKTAŞOĞLU, HÜSEYİN KAZIMPublication Metadata only Impact of high amylase level in drainage fluid after gastric cancersurgery: Is it a complication or suspicious biochemical measurement?(2019-02-01) HASBAHCECI, Mustafa; CENGİZ, Merve Büşra; AKÇAKAYA, ADEM; MALYA, FATMA ÜMİT; KUNDUZ, ENVER; Bektaşoğlu, HÜSEYİN KAZIM; AKÇAKAYA, ADEM; MALYA, FATMA ÜMİT; KUNDUZ, ENVER; BEKTAŞOĞLU, HÜSEYİN KAZIMPublication Open Access Comparison Of Surgical Technique And Results For Emergency Or Elective Femoral Hernia Repair(2019-01-01) KUNDUZ, ENVER; SORMAZ, ISMAIL; YAPALAK, YUNUS; Bektaşoğlu, HÜSEYİN KAZIM; GÖK, ALİ FUAT KAAN; KUNDUZ, ENVER; YAPALAK, YUNUS; BEKTAŞOĞLU, HÜSEYİN KAZIMBACKGROUND: Inguinal hernia affects 3–8% of the population. Femoral hernias are only a small number of groin hernias; however, femoral hernias are very important because these operations are generally emergency procedures, and bowel resections are frequently necessary. This study aims to compare surgical outcomes of patients with femoral hernias using different techniques under emergency or elective conditions. METHODS: Between April 2013 and November 2017, 52 patients with femoral hernias were admitted to the emergency department of the General Surgery Clinics at two university hospitals in Istanbul. The medical files of all the patients who underwent surgery with a diagnosis of a femoral hernia were retrospectively evaluated. The demographic data, hernia side information, sac contents, surgical technique, length of hospital stay, recurrence according to the last outpatient clinic and complications were retrospectively analyzed. RESULTS: The sex distribution of the cases was as follows: 88.5% (n=46) of the patients were female, and 11.5% (n=6) were male. The mean age was 62.9±16.49 years (31–91 years). There were no significant differences between the two groups, according to the hernia side (p=0.282). Thirteen of the elective cases (52%) were operated using open techniques, and 12 cases (48%) were operated using laparoscopic techniques. CONCLUSION: For the comparison of surgical techniques and outcomes, prospective randomized studies should be designed to standardize broad-based surgical techniques.Publication Metadata only Elastic Seton Placement in Treatment of Complex Anal Fistula: Analysis of 44 Patients(2018-03-01) BEKTAŞOĞLU, HÜSEYİN KAZIM; KUNDUZ, ENVER; BEKTAŞOĞLU, HÜSEYİN KAZIM; KUNDUZ, ENVERPublication Open Access Analysis of Appendiceal Neoplasms on 3544 Appendectomy Specimens for Acute Appendicitis: Retrospective Cohort Study of a Single Institution(2018-06-27) Destek, Sebahattin; Bektasoglu, HÜSEYİN KAZIM; Unver, NURCAN; Aydogan, CEYHUN; Timocin, GİZEM; KUNDUZ, ENVER; BEKTAŞOĞLU, HÜSEYİN KAZIM; ÜNVER, NURCAN; AYDOĞAN, CEYHUN; TİMOÇİN, GİZEM; DESTEK, SABAHATTİNBACKGROUND Appendiceal neoplasms are rare and generally determined in appendectomy specimens for acute appendicitis. Depending on a tumor's histopathology and size, appendectomy or right hemicolectomy are the surgical treatment options. Adenocarcinomas, mucinous neoplasms, goblet cell carcinoids and neuroendocrine tumors are the types of the primary appendiceal neoplasm histopathology. In this study, we aimed to determine the incidence of appendiceal neoplasms in an acute appendicitis cohort. Also, histopathological distributions, demographic data, preoperative radiological diagnosis, and intraoperative findings were revealed for analysis, retrospectively. MATERIAL AND METHODS Between October 2011 and September 2017, 3554 appendectomies were performed for acute appendicitis in Bezmialem University Hospital, Istanbul Turkey. The medical records of these consecutive 3554 patients were evaluated retrospectively. After the histopathological analysis of the appendectomy specimens, a total of 28 patients were detected as having appendiceal neoplasm including appendiceal adenocarcinoma, low grade mucinous neoplasia, and appendiceal neuroendocrine tumors. RESULTS Appendiceal neoplasms were determined in 28 out of 3554 acute appendicitis patients with an incidence of 0.78%. According to the histopathological types, 3 of the cases (10.7%) were appendiceal adenocarcinoma, 8 of the cases (28.5%) were low grade mucinous neoplasia, and 17 of the cases (60.8%) were neuroendocrine tumors. The overall incidence of the appendiceal neuroendocrine tumors was 0.48%. CONCLUSIONS The information obtained from our study suggests that pathological examination of the specimen may not be necessary if there is no doubt according to preoperative radiological diagnosis and/or intraoperative findings of the surgeon.
