Positive lymph node ratio as a prognostic factor for gastric cancer patients: Is it going to supersede positive lymph node number in guidelines?

Gastric malignancies constitute the sixth most common cancer with regards to incidence and have the fifth most mortality rates. Extended lymph-node dissection is the surgical modality of choice while treating advanced stage gastric cancer. It is yet a topic of debate, whether or not the amount of positive lymph nodes after a pathological examination following the surgical intervention is of prognostic value.

Transmesocolic approach in laparoscopic complete mesocolic excision for right sided colon cancers.

Introduction: A mesocolic plane, central vascular ligation (CVL) and proper proximal-distal margins are the essential components of complete mesocolic excision (CME). In the transmesocolic approach, we identify the middle colic vessels and enter the lesser sac through the mesocolon for ascending colon and caecum tumors.

Aim: To investigate the feasibility and identify the technical details of this technique.

Comparison of PET-CT and MRI for evaluation of axillary lymph nodes in early breast cancer patients.

Background: Evaluation of axillary lymph node in women with breast cancer is very important as it can change the initial treatment decision. None of the noninvasive methods used for assessment of axilla is accurate as sentinel lymph node biopsy (SLNB) yet. This study compared the diagnostic performance of 18-fluorodeoxyglucose positron emission tomography/ computed tomography (PET-CT) and Dynamic Contrast-Enhanced Magnetic Resonance Imaging (DCE-MRI) in preoperative axillary evaluation of women diagnosed with early breast cancer (EBC).

Laparoscopic Cholecystectomy after Acute Biliary Pancreatitis in a Patient with Situs Inversus Totalis.

Situs inversus totalis (SIT) is a rare disorder defined as symmetrical transposition of thoracic and abdominal organs. Laparoscopic cholecystectomy (LC) is a routine surgical operation and gold standard for symptomatic gallstones. LC can be challenging in SIT due to patient positioning on the operating table and the surgeon's operating position, especially for right-handed surgeons.

Do prognosis and clinicopathological features differ in young early-stage breast cancer?

Background: Breast cancer is the most frequently detected cancer and the leading cause of cancer-related death in women. Although it is mostly seen in older patients, breast cancer affects women aged 24 to >70 years, with poorer prognosis in young patients. Young age remains a controversial topic in the literature.

Comparison of laparoscopic and open resections for gastric gastrointestinal stromal tumors (GISTs).

Background: Gastrointestinal stromal tumors (GISTs) are the most common mesencyhmal tumors of the gastrointestinal tract. Today surgical resection is still the treatment of choice for primary gastric GISTs. This study compares the laparoscopic versus open surgical resection approaches of gastric GISTs.

Management of Gastric Tumor Perforation with Conservative Treatment during Neoadjuvant Chemotherapy.

Perioperative chemotherapy provides advantage for gastric cancer patients in terms of survival. A 56-year male with a diagnosis of locally advanced gastric carcinoma presented with complaints of acute abdominal pain; and was diagnosed as gastric tumor perforation during neoadjuvant therapy. Gastric perforation may occur during neoadjuvant chemotherapy for gastric cancer.

Management of Breast Cancer during the COVID-19 Pandemic.

The novel coronavirus disease (COVID-19) arises from the virus SARS-CoV-2 which is similar to the original SARS virus. The most common symptoms of the COVID-19 infection are fever, coughing and shortness of breath. According to the current data, the primary mode of transmission for the COVID-19 virus is between people through respiratory droplets and contact routes.

Management of perforation after endoscopic retrograde cholangiopancreatography.

Background: Endoscopic retrograde cholangiopancreatography (ERCP)-related perforation is an infrequent complication. It is associated with significant morbidity and mortality. The present study is an evaluation of experience with management and outcomes of ERCP-related perforations and a review of relevant literature.

Endometriosis within the sigmoid colon/extragenital endometriosis.

Endometriosis is the presence of endometrial glands and stroma outside the uterine cavity. Although it is common in women in the reproductive age, intestinal endometriosis is extremely rare and may lead to serious clinical problems. In this article, we present two rare cases of endometriosis localized in the sigmoid colon lumen.
