Prognostic Factors of Recurrence and Survival in Operated Patients with Colorectal Cancer.

: The recurrence of colorectal cancers is considered to be one of the greatest post-surgical complications that is affected by various factors. This study was designed to investigate the prognostic factors that affect the recurrence and survival of patients with colon and rectal cancers. : A retrospective study was performed on 380 patients with colorectal cancers who underwent surgery were enrolled in the study (152 patients with colon cancer and 228 patients with rectal cancer).

Effects of neuromodulation on treatment of recurrent anal fissure: A systematic review.

Background: Anal fissure is a linear tear in the distal anoderm most frequently occurring in the posterior midline. Lateral internal sphincterotomy is considered the gold standard for the treatment of this condition. To this date, several pharmacological and neuromodulatory therapies have been tried out as alternative non-invasive treatments for anal fissures, however, the efficacy of some of these methods remains to be understood.

Heart Rate Variability May Predict the Severity of Appendicitis: A Cross-Sectional Study.

Objective: To evaluate the role of heart rate variability (HRV) in predicting pre-operative severity of appendicitis.

Methods: In this cross-sectional study, 171 cases of acute appendicitis who underwent appendectomy were enrolled. Pre-anesthetic pulse rate of included patients were documented while the severity of appendicitis was determined by intra-operative evidences reported by two independent surgeons.

Report of 13-year survival of patients with colon and rectal cancers; lessons from Shiraz colorectal cancer surgery registry system of a level three medical center.

Background: Colorectal cancer (CRC) is the second most common cancer in women and the third most common cancer in men worldwide, with an increasing trend in its incidence in Asian countries. In the present study, we aimed to describe the 13-year results of patients with CRC based on the Shiraz Colorectal Cancer Surgery (SCORCS) registry system in patients with a pathologically confirmed diagnosis of colon cancer (CC) and rectal cancer (RC) undergoing surgery.

Methods: Between 2007 and 2020, 811 patients, including 280 patients with CC and 531 patients with RC, registered in SCORCS, were included in the present study.

Efficacy and safety of sequential neoadjuvant chemotherapy and short-course radiation therapy followed by delayed surgery in locally advanced rectal cancer: a single-arm phase II clinical trial with subgroup analysis between the older and young patients.

Purpose: This study was performed to investigate the efficacy and safety of short-course radiation therapy (SCRT) and sequential chemotherapy followed by delayed surgery in locally advancer rectal cancer with subgroup analysis between the older and young patients.

Materials And Methods: In this single-arm phase II clinical trial, eligible patients with locally advanced rectal cancer (T3-4 and/or N1-2) were enrolled. All the patients received a median three sequential cycles of neoadjuvant CAPEOX (capecitabine + oxaliplatin) chemotherapy.

Two cases of primary leiomyosarcoma of sigmoid colon treated with laparoscopic surgery: A case report and a review of literature.

Introduction And Importance: Leiomyosarcoma (LMS) of the colon is an extremely rare and highly invasive tumor arising from the muscularis propria of the gastrointestinal tract. After the introduction of oncogenic role of KIT by immunohistochemistry (IHC), the reported cases of gastrointestinal leiomyosarcoma were highly limited. True LMS of the colon is such a rare disorder that there isn't much description of its nature.

How Does Fat Mass Change in the First Year After Bariatric Surgery? A Systemic Review and Meta-Analysis.

This systematic review and meta-analysis investigated the time-course effect of different type of bariatric surgeries (BS) up to 1 year post-surgery on fat mass (FM) and body fat percentage (BFP) in patients with morbid obesity. We searched PubMed, Scopus, EMBASE, ISI web of science, and Cochrane databases from October 2002 until May 2020 with no restriction in the English language, to find studies examining the effect of BS on FM (kg) and BFP (%) in morbid obese patients. Meta-analysis of 103 studies carried out on data of 18,166 and 14,575 morbid obese patients following BS, showed that BS was associated with a substantial decrease in FM and BFP, respectively, in 1 month (- 8.

Prognostic Factors of Rectal Cancer in Southern Iran.

Background: Rectal cancer accounts for one-third of all colorectal cancer (CRC) cases. Due to physiological and anatomical differences, some researchers consider rectal cancer as a separate organ malignancy during the recent decades. However, limited studies have been conducted in this regard in Iran.

Prognostic Factors Affecting Short- and Long-Term Recurrence-Free Survival of Patients with Rectal Cancer using Cure Models: A Cohort Study.

Background: Understanding the prognostic factors affecting the recurrence-free survival (RFS) of patients with rectal cancer (RC) is the mainstay of care. The present study aimed to identify factors affecting both short- and long-term RFS of patients with RC using semiparametric mixture cure models.

Methods: The data were obtained from the database of the Colorectal Research Center of Shiraz University of Medical Sciences, Shiraz, Iran, which was collected during 2007-2017.

Optimizing compliance with surgical antimicrobial prophylaxis guidelines in patients undergoing gastrointestinal surgery at a referral teaching hospital in southern Iran: clinical and economic impact.

Background: Antibiotic prophylaxis is one of the major approaches to prevent surgical site infection. Despite the availability of international guidelines on it, the practice of antibiotic prophylaxis is still far from optimal. This study aimed to assess the impact of guideline implementation on the rational use of prophylactic antibiotics and its cost-saving effect in gastrointestinal surgery by clinical pharmacist intervention.

Outcomes of Implementation of Sacral Nerve Stimulation in Incontinent Patients in Shiraz.

Background: Fecal incontinence is a common disorder in old age; however, it may not threaten life, but it can cause morbidity and many problems. Sacral nerve stimulation (SNS) is a minimally invasive surgical procedure performed by chronic electrical stimulation of the nerves in the sacral plexus through a lead implanted at the S3 foramen. This study aimed to evaluate the outcomes of SNS in Shiraz.

Effects of Stapled Hemorrhoidopexy on Anorectal Function: A Prospective Randomized Controlled Trial.

Background: Stapled hemorrhoidopexy is a safe and acceptable alternative to traditional hemorrhoidectomy with shorter hospital stay, better satisfaction, and less postoperative pain. There have, however, been reports on early and late complications. Therefore, the present study was designed to assess the impact of stapled hemorrhoidopexy on anorectal function and continence.

How the anal gland orifice could be found in anal abscess operations.

Background: On an average 30-50% of patients who undergo incision and drainage (I and D) of anal abscess will develop recurrence or fistula formation. It is claimed that finding the internal orifice of anal abscess to distract the corresponding anal gland duct; will decline the rate of future anal fistula. Surgeons supporting I and D alone claim that finding the internal opening is hazardous.
