Background and Objectives: Perforation is a rare complication of gastric carcinoma and generally not diagnosed preoperatively. To clarify the clinicopathologic characteristics of patients with this condition we reviewed 13 cases of gastric cancer perforation who required emergency surgery. Methods: A total of 13 patients with gastric cancer perforation were retrospectively reviewed. The clinicopathological features including tumor stage and survival and also the type of treatment were analyzed and compared to literature data. Results: There were 13 patients (10 males and 3 females) with a mean age of 59.0 ± 9.56 years. The incidence of perforated gastric cancer was 9.6% among gastric carcinoma and 4.2% of all gastric perforation cases. The perforation was more frequently in stage III–IV (2–10), but one case of stage II (T3N0M0) gastric cancer was also observed. None of the patients had curative resection or radical lymph-node dissection. Six (46%) patients were treated by palliative, local surgery. Emergency gastrectomy were performed in 7 (54%) patients. Overall 30-day mortality rate was % 46. The overall survival time was 128.2 ± 184.8 days for all patients, it was 52.8 ± 52.9 days for locally treated group, and 192.9 ± 235.4 days for patients who underwent resectional surgery. The difference between the treatment groups was not significant Conclusion: Perforation usually occurs in advanced stages of gastric cancer. These patients had a poor prognosis because of the presence of advanced cancer.

Intestinal obstruction due to sigmoid volvulus during pregnancy is rare. The presenting signs/symptoms seen in these patients are the same as with non-pregnant patients. Fetal and maternal mortality rates are higher during pregnancy due to delays in diagnosis. We aimed to present four patients diagnosed with sigmoid volvulus during pregnancy and puerperium in our clinic. Diagnosis requires a high index of suspicion in a patient who presents with complaints of abdominal pain and evidence of bowel obstruction. Prompt intervention is necessary to minimize maternal and fetal morbidity and mortality.

The drainage of abdominal cavity by means of tube drains is the oldest method. The herniation of gallbladder through the abdominal wall is very rare. Although there are studies informing evisceration of organs such as small intestines and ovary from drain site; at the literature scanning, no publication has been met with advising gallbladder evisceration from the Pezzer drain site so far.

Aims and background: YKL-40 is secreted by several types of tumors. Increased serum YKL-40 levels have been reported in prostate, glioblastoma, breast and colorectal cancers. Determination of YKL-40 levels may serve as a valuable biomarker for the diagnosis and treatment of gastric cancer. The purpose of this study was to determine the serum YKL-40 levels expressed in gastric carcinomas. Methods: Between 2009 and 2011, we retrospectively reviewed 100 patients with gastric cancer and compared their serum samples to 75 healthy volunteers. YKL-40 levels were determined by an enzyme-linked immunosorbent assay (ELISA). Results: We found significantly higher serum levels of YKL-40 in patients with gastric cancer compared to the healthy population ( P < 0.0001). We also found significant differences in serum YKL-40 levels between female and male patients with gastric cancer ( P < 0.01). Conclusions: YKL-40 is over-expressed in gastric cancer, suggesting a more aggressive phenotype. YKL-40 may be a useful serum biomarker for gastric cancer identification, and future studies should focus on the role of YKL-40 in the tumorigenesis of gastric cancer and responsiveness toward treatment.

To ascertain the factors that govern morbidity, mortality, and recurrence in incarcerated femoral hernia. Observational study. Department of General Surgery, Faculty of Medicine, Van Yuzuncu Yil University, Van, Turkey, between January 2010 and January 2020. This observational study included patients operated on due to incarcerated femoral hernias under emergency conditions. The preoperative, intraoperative, and postoperative parameters of the patients were gathered. The study excluded pregnant patients and patients in the pediatric age group (0‒18 years). Mann-Whitney U-test was used to compare quantitative variables. In addition, a Chi-square test and Likelihood-ratio test were used to compare the qualitative variables. A p-value <0.05 was deemed statistically significant. The mean age of the 50 patients was 54.56 ± 19.34 (19‒91) years and the female/male ratio was 33:17. The morbidity, mortality, and recurrence rates of the study were 14%, 4%, and 6% respectively. Higher morbidity was observed in patients who had preoperative nausea (p = 0.003), vomiting (p <0.001), tachycardia (p <0.001), recurrent hernia (p <0.001), surgery under general anesthesia (p <0.001) or who underwent both laparotomy (p = 0.007) and visceral resection during surgery (p <0.001). Higher rates of mortality were observed in patients who had preoperative tachycardia (p = 0.054) or visceral resection during surgery (p = 0.029). However, the study identified no factors affecting recurrence. In cases of incarcerated femoral hernia, symptoms of intestinal obstruction or signs of strangulation are more important in the development of postoperative morbidity. In addition, the probability of mortality is higher in patients who had preoperative tachycardia and in patients who underwent visceral resection. To the extent possible, regional anesthesia should be preferred in suitable cases. Key Words: Femoral hernia, Laparotomy, Morbidity, Mortality, Recurrence.
