Telescopic Dissection as a Cost-Effective Alternative to Balloon Trocar for Preperitoneal Dissection in Total Extraperitoneal Inguinal Hernia Repair.

Background: Total extraperitoneal (TEP) approach is one of the commonly used minimally invasive method in inguinal hernia repair. There are limited data that compares the results of the telescopic dissection and balloon trocar for preperitoneal dissection. In our study, we aimed to retrospectively evaluate the TEP cases performed at our center and compare the results of these two techniques. Methods: TEP cases performed between 2020 and 2024 were evaluated. Strangulated and recurrent hernia cases were excluded. Telescopic dissection and balloon trocar techniques were compared in terms of conversion, postoperative pain, complications, and recurrence. Results: A total of 177 patients were included. Telescopic method was used in 122 cases, while a balloon trocar was used in 55 cases. The median age was 50 years (range: 20-86), and 163 patients (92%) were male. Bilateral inguinal hernia was present in 61 patients (35%). The median operative time was 100 minutes (IQR: 80-120 minutes). Conversion was required in a total of 3 cases (1.5%); specifically, the transabdominal preperitoneal method was employed in 2 cases, and Lichtenstein-style anterior approach hernia repair was performed in one case. Between the telescopic dissection and balloon trocar groups, no significant differences were observed in operation time (P = .407), conversion rates (P = .228), postoperative pain scores (P = .505, P = .264, P = .681, P = .743), complication rates (P = .205), or recurrence rates (P = .311). Conclusions: The results of using a balloon trocar and telescopic dissection in inguinal hernia repair with TEP are similar, and telescopic dissection could be a cost-effective alternative to the balloon trocar.

Factors predict prolonged colonoscopy before the procedure: prospective registry study.

BACKGROUND: Colonoscopy difficulty and procedure time can vary between cases, posing challenges for daily scheduling in endoscopy units. In the literature, cecal intubation time (CIT) is commonly used to assess colonoscopy difficulty, yet there is debate regarding the factors influencing CIT. This prospective observational study aimed to evaluate the factors influencing CIT. METHODS: In this single-center, prospective, observational study, 915 patients who underwent colonoscopy between July 2023 and April 2024 were evaluated. Failure to achieve cecal intubation due to poor bowel preparation and a history of colorectal surgery were considered as exclusion criteria. Patients with a CIT ≥ 11 min or those with technically failed cecal intubation were categorized into the prolonged CIT subgroup, while those with a CIT < 11 min were analyzed in the normal CIT subgroup. Patients were evaluated based on demographic characteristics, clinical parameters, and colonoscopy results. RESULTS: A total of 902 patients included in the final analysis. The median age was 55 years and 55.4% of them were women. The cecal intubation rate was 97.5% (892 patients). The polyp, adenoma, and malignancy detection rate were 27.4, 20.7, and 1.9%, respectively. Median cecal intubation time (CIT) was 6 min (Interquartile range: 4-8). In multivariate analysis, body mass index ≤ 18.5, previous abdominal surgery, increased Wexner Constipation Score, and lesser endoscopist experience were associated with prolonged CIT. CONCLUSIONS: BMI, previous abdominal surgery, severity of constipation, and the experience of endoscopist may affect CIT. Considering these factors during daily planning in the endoscopy unit can lead to more efficient facility utilization.

Evaluation of Antral Biopsies Obtained in Endoscopically Normal Esophagogastroduodenoscopy: A Retrospective Cohort Study.

BACKGROUND: The requirement for routine biopsy sampling in esophagogastroduodenoscopy (EGD) with normal endoscopic findings is a subject of debate. In this study, patients who had normal endoscopic findings in EGD and underwent biopsy sampling were retrospectively analyzed. METHODS: This single-center retrospective cohort study included 671 patients who underwent EGD between 2021 and 2023 in the Sisli Hamidiye Etfal Training and Research Hospital Surgical Endoscopy Unit. All patients had normal endoscopic findings and a sampling biopsy was performed on all patients included. Patients were evaluated based on demographic and clinicopathologic findings. This study was registered to ClinicalTrials.gov (NCT06269380). RESULTS: Two hundred sixty patients (38.7%) have abnormal histopathologic findings. Helicobacter pylori positivity was detected in 200 (29.8%) patients. Intestinal metaplasia (IM) was present in 80 of 260 patients (30.8%). The frequency of IM was higher in older age groups and cases with mild gastritis ( P <0.001). The frequency and severity of gastritis were associated with increased H. pylori positivity and density ( P <0.001). CONCLUSIONS: The biopsy sampling may contribute to the diagnosis and treatment process in cases where normal endoscopic findings are observed during EGD.

Conservative Approach For The Management Of Bilateral Pneumothorax And Pneumomediastinum After Laparoscopic Totally Extraperitoneal Inguinal Hernia Repair.

Laparoscopic totally extraperitoneal inguinal hernia repair is considered a common and safe procedure. Here, we present the case of a 31-year-old male with right indirect inguinal hernia and no medical history. The patient underwent laparoscopic totally extraperitoneal inguinal hernia repair and the operation was completed successfully. During extubation, subcutaneous emphysema was noted at the neck, chest, and above the nipples. Tracheal injury was excluded by the anaesthesiologists and otorhinolaryngologists. On arterial blood gas, the patient's oxygen saturation was 95% with nasal oxygen support. The patient was followed-up closely in the general surgery inpatient clinic. Computed tomography was performed, on which bilateral pneumothorax and pneumomediastinum were noted. Conservative management was planned and the patient was discharged on the fourth postoperative day. Laparoscopic totally extraperitoneal inguinal hernia repair is considered a routinely applied safe procedure, however, appropriate care should be taken to avoid possible complications.

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. In this study, it is aimed to evaluate the prognostic significance of positive lymph nodes following the surgery. A total of 193 patients who underwent curative gastrectomy between January 2011 and December 2015 have been considered for a retrospective data collection. The cases with R1-R2 resections, palliative or emergent surgeries are excluded. Metastatic to total number of lymph nodes, corresponded a ratio which was analyzed in this survey and practiced as a predictive parameter of disease outcome. This survey includes 138 male (71.5%) and 55 female (28.5%) patients treated between 2011 and 2015 in our clinic. The survey follow-up duration of the cases range between 0, 2, and 72 months, corresponding an average of 23.24 ± 16.99 months. We calculated cutoff value of 0.09 with, sensitivity is 76.32% for positive to total number of lymph nodes ratio, whereas specivity applies for 64.10%, positive predictive value for 58% and negative predictive value for 80.6%. Positive lymph node ratio has a prognostic value in terms of predicting the prognosis of the patients with gastric adenocarcinoma following a curative gastrectomy. This might in long term contribute to the prognostic analysis of patients if integrated in the current staging system.

Clinical significance of the largest histopathological metastatic lymph node size for postoperative course of patients undergoing surgery for gastric cancer.

Aim: The aim of this study was to investigate the effect of the largest metastatic lymph node (MLN) size on postoperative outcomes of patients with stage II-III gastric cancer (GC). Methods: A total of 163 patients with stage II/III GC who underwent curative surgery were included in this single-center retrospective study. The lymph nodes were counted, each lymph node was analyzed for metastatic involvement by histopathological examination, and the diameter of the largest metastatic lymph node was recorded. The severity of postoperative complications was assessed by Clavien-Dindo classification system. Two groups of 163 patients were defined according to ROC analysis with cut-off value of histopathologically maximum MLN diameter. A comparative analysis of demographic and clinicopathological characteristics of the patients and their postoperative outcomes were performed. Results: The median hospital stay was significantly longer in patients with major complications compared to patients without major complications [18 days (IQR: 13-24) vs. 8 days (IQR: 7-11); (p < 0.001)]. The median MLN size was significantly larger in deceased patients compared to survived [1.3 cm (IQR: 0.8-1.6) vs. 0.9 cm (IQR: 0.6-1.2), respectively; (p < 0.001)]. The cut-off value of MLN size predicting mortality was found as 1.05 cm. MLN size ≥1.05 cm had nearly 3.5 times more negative impact on survival. Conclusions: The largest metastatic lymph node size had a significant association with survival outcomes. Particularly, MLN size over 1.05 cm was associated with worse survival outcomes. However, the largest MLN was not shown to have any effect on major complications. Further prospective and large-scale studies are required to draw more precise conclusions.

Clinical significance of the histopathological metastatic largest lymph node size in colorectal cancer patients.

Background: The metastatic lymph nodes (MLN) are interpreted to be correlated with prognosis of the colorectal cancers (CRC). The present retrospective study aimed to investigate the clinical significance of the largest MLN size in terms of postoperative outcomes and its predictive value in the prognosis of the patients with stage III CRC. Methods: Between May 2013 and December 2018, a total of 101 patients who underwent curative resection for stage III CRC retrospectively reviewed. All patients were divided into two groups regarding cut-off value (<1.05 cm and ≥1.05 cm) of maximum MLN diameter measured histopathologically. A comparative analysis of demographic and clinicopathological characteristics of the patients and their postoperative outcomes were performed. Results: Two groups carried similar demographic data and preoperative laboratory variables except the lymphocyte count, hematocrit (HCT) ratio, hemoglobin level and mean corpuscular volume (MCV) value (p<0.05). The patients with MLN diameter ≥1.05 cm (n=46) needed more erythrocyte suspension and were hospitalized longer than the patients with a diameter <1.05 cm (n=55) (p=0.006 and 0.0294, respectively). Patients with MLN diameter < 1.05 cm had a significantly longer overall survival than patients with MLN diameter ≥ 1.05 cm (75,29 vs. 52,57 months, respectively). Regarding the histopathologic features, the patients with MLN diameter ≥1.05 cm had larger tumor size and higher number of MLN than those with diameter <1.05 cm (p=0.049 and 0.001). Conclusion: The size of MLN larger than 1.05 cm may be predictive for a poor prognosis and lower survival of stage III CRC patients. The largest MLN size may be a proper alternative factor to the number of MLNs in predicting prognosis or in staging CRC patients.

Management of Nonocclusive Mesenteric Ischemia in Patients with Cardiac Failure.

AIM: This study aimed to evaluate the surgical procedures, outcomes, and prognostic factors in patients with ischemic heart disease who were operated on due to nonocclusive mesenteric ischemia (NOMI). MATERIAL AND METHODS: This research contains all patients diagnosed with congestive heart failure and NOMI between January 2011 to January 2020. The patients who had angiography or CT that showed occlusion of more than 50% in any of the main branches of the mesenteric artery or patients who presented with symptoms in correlation with a total occlusion were excluded from the study. Patients who underwent coronary heart surgery but were not diagnosed with congestive heart failure and those with atrial fibrillation also were excluded from the study. Patients divided into two groups, according to a medical database. RESULTS: A significant difference was found between the surviving and non-survivor groups in minutes, in terms of median time to segmenter intestinal resection (P = 0.042). CONCLUSION: An early diagnosis and surgical segmental intestinal resection before peritonitis worsens can be the key to better prognosis for NOMI patients.

The first case: acute abdomen due to gastric gastrointestinal stromal tumor perforation with synchronous renal cell carcinoma.

AIM: Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal neoplasms of the gastrointestinal tract and they may coexist with renal cell cancers (RCC). The main treatment method of GIST and RCC is curative elective surgery. Surgery followed by oncological treatment with sunitinib is the main treatment option when these tumors coexist. CASE REPORT: A 32-year-old male, after a traffic accident applied to the emergency department. A thoraco-abdominopelvic computed tomography was performed, which demonstrated the presence of diffuse hemorrhagic fluid in the abdomen with 11x10 cm exophytic gastric mass and 2 x 2 cm right renal mass. After emergent laparotomy with gastric wedge resection and partial nephrectomy, patient was discharged uneventfully. CONCLUSIONS: If the patient's clinical condition is suitable for surgery, both tumors can be removed simultaneously, even in emergency situations. Thus, difficulties and complications that may occur during follow-up and the second operation can be avoided. KEY WORDS: Acute Abdomen, Gastrointestinal Stromal Tumor, Renal Cell Carcinoma.

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. While the treatment of choice for these perforations was surgery in the past, it is now shifting towards a minimally invasive or non-invasive approach. We used the minimally invasive treatment approach with nasogastric drainage, intravenous antibiotics and proton pump inhibitors, which was effective in the treatment of perforation. Althrough, conservative treatment approach may be an effective management option in selected patients with gastric cancer perforation. Key Words: Gastric cancer, Neoadjuvant chemotherapy, Perforation.
