Neutrophil to Lymphocyte Ratio in Patients Who Received Neoadjuvant Treatment before Gastrectomy.

Background: The neutrophil to lymphocyte ratio (NLR) has demonstrated prognostic value in various malignant conditions, including gastric adenocarcinoma. However, chemotherapy may affect NLR.

Objectives: To evaluate the prognostic value of NLR as an accessory decision-making tool in terms of operating patients after neoadjuvant chemotherapy in patients with resectable gastric cancer.

Management of Acute Appendicitis during the COVID-19 Pandemic: A Single Tertiary Center Experience.

Background: The coronavirus disease-2019 (COVID-19) outbreak had an effect on healthcare.

Objectives: To evaluate the presentation and management of patients with acute appendicitis.

Methods: A retrospective study was conducted of all patients presenting with acute appendicitis to the emergency department of a large tertiary center during March and April 2020.

Increased Rate of Complete Pathologic Response After Neoadjuvant FOLFIRINOX for BRCA Mutation Carriers with Borderline Resectable Pancreatic Cancer.

Background: Neoadjuvant FOLFIRINOX is a standard-of-care treatment for BRPC patients. Patients with gBRCAm who have demonstrated improved response to platinum-based chemotherapy may have impaired homologous repair deficiency. This study aimed to describe the pathologic complete response rate and long-term survival for patients with germline BRCA1 or BRCA2 mutation (gBRCAm) and borderline resectable pancreatic cancer (BRPC) treated with neoadjuvant FOLFIRINOX.

Perineal Stapled Rectal Prolapse Resection in Elderly Patients: Long-term Follow-up.

Background: Full-thickness rectal prolapse has a significant negative impact on quality of life. The therapeutic options, specifically in elderly patients, are imperfect. Perineal stapled rectal prolapse resection is a novel operation for treating external rectal prolapse.

Modified Doppler-guided laser procedure for the treatment of second- and third-degree hemorrhoids.

Background: Hemorrhoids are a common anorectal condition with a major medical and socioeconomic impact. Owing to the high incidence of symptomatic hemorrhoids in the adult population together with the risk of complications of traditional surgery, researchers are seeking less invasive methods of hemorrhoidal treatment.The aim of this study was to present our experience with the mini-invasive Doppler guided hemorrhoidal laser procedure (HeLP) in symptomatic 2nd and 3rd degree hemorrhoids with absent or minimal mucosal prolapse.

Risk Factors for Complications of Total/Subtotal Gastrectomy for Gastric Cancer: Prospectively Collected, Based on the Clavien-Dindo Classification System.

Background: Recent studies have analyzed risk factors associated with complications after gastric cancer surgery using the Clavien-Dindo classification (CD). However, they have been based on Asian population cohorts (Chinese, Japanese, Korean).

Objectives: To prospectively analyze all post-gastrectomy complications according to severity using CD classification and identify postoperative risk factors and complications.

RNAi therapy targeting KRAS in combination with chemotherapy for locally advanced pancreatic cancer patients.

Purpose: The miniature biodegradable implant siG12D-LODER™ was inserted into a tumor and released a siRNA drug against KRAS(G12D) along four months. This novel siRNA based drug was studied, in combination with chemotherapy, as targeted therapy for Locally Advanced Pancreatic Cancer (LAPC).

Methods: An open-label Phase 1/2a study in the first-line setting of patients with non-operable LAPC was initiated.

Diffusion tensor magnetic resonance imaging of the pancreas.

Purpose: To develop a diffusion-tensor-imaging (DTI) protocol that is sensitive to the complex diffusion and perfusion properties of the healthy and malignant pancreas tissues.

Materials And Methods: Twenty-eight healthy volunteers and nine patients with pancreatic-ductal-adenocacinoma (PDAC), were scanned at 3T with T2-weighted and DTI sequences. Healthy volunteers were also scanned with multi-b diffusion-weighted-imaging (DWI), whereas a standard clinical protocol complemented the PDAC patients' scans.

Laparoscopic subtotal gastrectomy for gastric cancer.

Background: The use of laparoscopy in the treatment of gastric malignancy is still controversial. However, several reports suggest that the laparoscopic approach may be safe and applicable. The aim of this study was to review our experience with laparoscopic gastrectomy for gastric malignant tumors amenable to subtotal gastrectomy, and assess the oncologic outcome.

[Laparoscopic colon and rectal surgery--after ten years and 350 operations].

Background: Within a decade since laparoscopy was used in cholecystectomy it has become the preferred approach in many abdominal procedures. Laparoscopic colon and rectal surgery has not yet been adopted by the majority of surgeons, due to technical complexity and reservation regarding its oncological safety. As data and experience accumulate, this attitude is gradually changing.

Laparoscopically assisted reversal of Hartmann's procedure.

Background: Restoration of bowel continuity after Hartmann's procedure is a major surgical procedure associated with substantial morbidity and occasional mortality. The authors review their experience with laparoscopically assisted reversal of Hartmann's procedure (LARH) to assess difficulties and potential advantages associated with this procedure.

Methods: A retrospective chart review of a prospectively entered database was performed to identify patients who underwent LARH over a period of 7 years.
