Article Synopsis
  • The study examined how neoadjuvant therapy affects shrinkage in the distal surgical margin (DSM) of rectal cancer specimens after formalin fixation.
  • It involved measuring the DSM in 61 resected cancer specimens before and after fixation, comparing shrinkage rates based on neoadjuvant treatment and tumor regression grade (TRG).
  • Results showed that patients receiving neoadjuvant therapy had a significantly higher DSM shrinkage rate (34.7%) compared to those who did not (23.7%), particularly in specimens with better clinical responses.

Aim: The present study aimed to investigate the effect of the presence of polyposis in sporadic early-onset colorectal cancer (EOCRC) on clinicopathological and oncological outcomes.

Methods: The retrospective study included patients with sporadic colorectal cancer aged 16 to 50 years who underwent curative resection at the general surgery clinics in two healthcare centers between 2013 and 2019. Patients were divided into two groups: polyposis and nonpolyposis.

Purpose: The purpose of our study was initially to explore the prognostic role of LDH-to-albumin ratio in patients with colorectal carcinoma (CRC) undergoing curative resection.

Methods: The retrospective study included 295 CRC patients that underwent curative resection. According to time-dependent receiver operating characteristics (ROC) analysis, the optimal cutoff value for pretreatment LDH-to-albumin ratio was 52.

Introduction: Whether complete splenic flexure mobilization (SFM) is required remains a controversial issue and there are numerous approaches regarding the performance of this procedure.

Aim: To investigate the effect of SFM performed with a medial-to-lateral and superior-to-inferior approach on early clinical outcomes in laparoscopic resection of rectal cancer.

Material And Methods: The SFM procedure was initiated by the ligation of the inferior mesenteric vein followed by dissection extending from the upper border of the pancreas to the splenic hilum through the gastrocolic space.

The median arcuate ligament syndrome is a rare clinical condition with no standardized method of laparoscopic treatment. Exposure of the aorto-celiac axis might be considered as the most challenging part of the surgical procedure. It is important to secure total release while enabling adequate vision as the compressing musculofibrous ligament is located in the deepest part of the aorto-celiac hiatus.

Background Superior mesenteric artery syndrome (SMAS) results from the compression of the third part of the duodenum between the aorta and the proximal part of the superior mesenteric artery (SMA). Clinical presentation of SMAS is characterized by the dilatation of the proximal part of the third part of the duodenum. SMAS is a rare cause of the upper gastrointestinal system (UGS) obstruction.

Due to the rarity and large diversity of the primary retrorectal tumors (RTs), the diagnoses are often difficult and they can be misdiagnosed. We present our experience in light of scarce information available on the clinical manifestations of RTs. The retrospective study included 17 patients diagnosed as RTs between January 2004 and January 2014.

Background/aims: Levels of the hormones ghrelin and leptin in rat models of acute pancreatitis (AP) have been investigated in several experimental studies. However, there are very few clinical studies addressing the connection between hormone levels and AP. A few recent studies investigating the changes in ghrelin and leptin levels in patients with AP have been reported; however, our study is the first clinical study to investigate the change of nesfatin-1 levels in patients with gallstone-induced AP.

Background: Early prediction of disease severity in acute pancreatitis (AP) is crucial. The aim of this study was to investigate the body-mass index (BMI), plasma leptin, nesfatin-1 and ghrelin levels as potential markers predicting peripancreatic necrosis and severity in acute pancreatitis.

Methods: In the study period, 97 consecutive patients with AP were prospectively analysed.

Introduction: We aimed to analyze the approaches to the diagnosis and treatment of patients with fascioliasis in light of current literature.

Methodology: Thirty-nine patients with fascioliasis admitted to the Surgery Clinic of Dicle Medical Faculty (Turkey) were included in this study. The demographic, clinical, diagnostic, treatment and outcome data were analyzed retrospectively.

Haemorrhoidal disease (HD) is one of the most common diseases encountered by the clinicians of general surgery. Chronic constipation, pushing during defecation and increased abdominal pressure play an important role in development of haemorrhoidal disease. Patients with ankylosing spondylitis (AS) frequently use the Valsalva manoeuvre in their daily lives, which may increase the abdominal pressure, leading to formation of haemorrhoids.

Background/aims: Mesenteric ischemia/reperfusion injury induces a systemic response and releases harmful substances that may affect distant organs such as the lung, liver and kidney. We designed this study to determine if curcumin has protective effects against mesenteric ischemia/reperfusion injury and mesenteric ischemia/reperfusion-induced intestinal and distant organ injury.

Methods: Forty Wistar-Albino rats were divided into four groups as: sham, control, ischemia/reperfusion, and ischemia/reperfusion+curcumin.

Background: The principles of the treatment of rectal injuries have been determined based on the experiences gained from military injuries. While adopting these principles in civilian life, it is essential to know the characteristics of civilian rectal injuries as well as the risk factors affecting morbidity.

Methods: The characteristics of 29 inpatients who had been treated due to rectal injuries caused by gunshot wounds and penetrating devices were evaluated.

Background: The aim of this study was to investigate the possible protective role of antioxidant treatment with ellagic acid (EA) on lung injury after intestinal ischemia-reperfusion (I/R) injury using biochemical and histopatological approaches.

Materials And Methods: Forty rats were divided into four groups as control, control + EA, I/R, and I/R + EA. The control and control + EA groups were also anesthetized and subjected to laparotomy, but without clamp application.

While diaphragmatic hydatid disease is a rare condition, subcutaneous extension of the disease is very rare. A 33-year-old female visited our clinic due to swelling on the right upper quadrant of the abdomen. Thoraco-abdominal CT scan and MRI revealed a hydatid cyst (110 x 98 x 78 mm) located in the costal part of the hemidiaphragm extending into the preperitoneal space and protruding intercostally to a subcutaneous area.

Background: Intra-abdominal hypertension (IAH) has negative effects on the functions of intra- and extra-abdominal organs and systems. Intra- and extraperitoneal hemorrhage, diffuse intestinal and retroperitoneal edema, intestinal ileus or obstruction, necrotizing pancreatitis, intra-abdominal packing, intra-abdominal sepsis, and pneumoperitoneum can all cause IAH. No studies were found in the literature relating to the effects of IAH on the endocrine functions of the pancreas.

Laparoscopic adjustable gastric banding (LAGB) causes significant weight loss in morbidly obese adults. However, its consequences on nutritional status still remain unclear. There are a few studies determining the nutritional status after LAGB and none have focused on the serum levels of zinc (Zn), copper (Cu), and ceruloplasmin (CP).

Ellagic acid (EA) is a natural polyphenolic compound. Although, modulator effects of EA on copper (Cu) and zinc (Zn) levels in some liver diseases have been reported in experimental animals, its effects in obstructive jaundice (OJ) has not been clarified. We aimed to evaluate potential effects of EA on Cu and Zn levels in liver and serum of cholestatic rats.
