Background/Aim Although rare, parasitic infection can cause acute appendicitis and result in contamination of the peritonea during appendectomy. The goal of this study was to summarize our experiences with parasitic appendicitis and describe a novel laparoscopic technique to prevent contamination. Method All patients diagnosed with acute appendicitis who underwent appendectomy between January 2016 and January 2017 were included in the study. All appendectomies were performed using the standard three-port laparoscopic method, and a video recording was made of each procedure. Following separation of the mesoappendix, a single endoloop was placed in the base of the appendix, and the appendix was then transected 3-4 mm above the clamp with the aid of a thermal cauterizing/sealing device. The appendix was extracted from the 10 mm trocar hole below the umbilicus and placed inside a bag prepared from a glove. After pathological confirmation of parasitic appendicitis, medical records were retrospectively analyzed in each case for whether peritoneal contamination had occurred or not. Results Out of 97 appendectomies, parasitic infection was observed in 4 cases, as confirmed by pathological examination. In two of these patients, E. vermicularis was detected, while the other two were infected with Balantidium coli. Intraoperative contamination did not occur in any of the cases, and retrospective review of the video recordings indicated no peritoneal contamination. Conclusion As a result of the coagulation and sealing effects of thermal devices, airtight seals were created on the residual appendiceal stumps, and consequently, no contamination was observed in any of the cases.

Objective: In this study, we aimed to investigate the rates and causes of incisional hernia that developed in the postoperative follow-up of patients who underwent liver transplantation. Material and method:The results of patients who underwent LT by using three different incisions at the İstanbul Yeni Yüzyıl University Gaziosmanpaşa Hospital organ transplant center between January 2015 and December 2019 were retrospectively analyzed. Patients were divided into Chevron (group-1), reverse T (group-2), and J incisions (group-3) and hernia development rates were examined.Results: There was no significant difference in terms of incisional hernia in groups 1 and 2 according to the incision type (p = .723). Incisional hernia rate was significantly lower in the J incision group (p < .001). When the factors that increase the development of hernia in all LT patients were examined, it was seen that male gender (p = .021), high BMI rate (p = .003), postoperative bleeding (p = .018), and wound infection (p = .039) caused a significant increase in risk. Conclusion:The incision, which is made during liver transplant, is important for the development of hernia. The J incision has a low hernia development rate without causing access problems. Regardless of the incision, high BMI index, male gender, postoperative bleeding, and wound infection increase the development of incisional hernia in liver transplant patients.

Pancreatic hydatid cyst is a rare disease found mostly in endemic regions. Having no specific clinical signs, it may present with tension related abdominal pain, dyspepsia, a palpable mass, and signs of external pressure on the surrounding organs in accordance with localization of the lesion. Pancreatic carcinoma as a neoplastic pathology with poor prognosis can have various clinical presentations changing with localization of the tumor which sometimes has cystic components. Due to the distinct nature of these pathologies, surgical approach can be fairly different. In this report, we present a case of a 70-year-old patient who had an isolated hydatid cyst in the tail of the pancreas with an incidental pancreatic carcinoma in the corpus of the pancreas. The patient was treated with a subtotal pancreatectomy, having no problems in the postoperative period leading to uncomplicated discharge.

Objective With each passing day, dual-energy computed tomography (DECT) is being used more frequently in the evaluation of abdominal pathologies. In this article, we aimed to assess the role of dual-energy CT in locating gastrointestinal perforations, which are among the causes of acute abdomen. Materials and methods All patients who underwent DECT due to acute abdomen in a COVID-19 designated hospital between June 1st, 2020 and December 31st, 2020, who were found to have gastrointestinal tract (GIT) perforation and underwent surgery were included in the study. DECT results and intraoperative findings of the patients were compared. Results Thirteen patients (nine males and four females) who underwent DECT for acute abdomen and were diagnosed with perforation in the gastrointestinal system were included in the study. The mean age of the patients was 57.6 years (range: 11-85 years). Two patients had gastric perforation, three had duodenal perforations, and one patient had a perforation in the gallbladder wall. Two patients were diagnosed with jejunal perforations, one patient with Meckel's diverticulum, and three patients with colorectal perforation. Although free air was detected in the abdomen of one patient, perforation could not be located. In patients with GIT perforation who were operated on following DECT imaging, the perforation location shown on DECT correlated 100% with the perforation locations detected during surgery. Conclusion DECT is significantly effective in planning surgical treatment and determining the foci of perforation in GIT perforations.
