Department of General Surgery and Anatomy, Faculty of Medicine, Ankara University, Sıhhıye, 06100, Ankara, Turkey.

Background: Pelvic surgery carries an inherent risk of autonomic nerve injury leading to genitourinary and bowel dysfunction due to the close proximity of the superior hypogastric plexus (SHP). The aim of this study was to define the detailed anatomy of SHP and identify its relationship with the vascular landmarks and ureters for pelvic autonomic nerve-preserving surgery.

Methods: A cadaveric study on the detailed anatomy of the SHP was conducted in our surgical anatomy research unit. Read More

J Surg Case Rep 2022 May 17;2022(5):rjac194. Epub 2022 May 17.

Department of Colon and Rectal Surgery, Summa Health System, Akron, OH, USA.

We present a case of a chronic perineal sinus following abdominoperineal resection with management via endoscopic electrocauterization. This patient presented with 1 year of bloody, mucus drainage from a perineal wound following abdominoperineal resection for anastomotic leak and stricture from a remote low anterior resection for T2N1 rectal cancer. We describe a novel use of endoscopic electrocautery to debride, de-epithelialize and ultimately eliminate the sinus cavity. Read More

Department of Gastrointestinal Radiation Oncology, Division of Radiation Oncology, The University of Texas MD Anderson Cancer Center, Houston, TX.

Background: Definitive radiotherapy with concurrent chemotherapy is curative for non-metastatic squamous cell carcinoma of the anus (SCCA). However, the true impact of chemoradiation on long-term functional outcomes is poorly understood due to limited follow up and patient-reported outcomes (PROs).

Methods: We conducted a cross-sectional survey of 248 patients with SCCA treated with definitive intensity-modulated radiation (IMRT) and concurrent chemotherapy from 2010-2018 who were alive and without recurrence. Read More

Department of Hernia and Colorectal Surgery, The Second Hospital of Dalian Medical University, Dalian, People's Republic of China.

Background: The E2 factor (E2F) family of transcription factors is dysregulated in numerous cancer types and may play a vital role in the development of various malignancies. However, to our knowledge, the specific function of each of the E2Fs and their relation to the disease prognosis of colorectal cancer (CRC) patients remain unknown.

Materials And Methods: We used different publicly available databases and tools, such as ONCOMINE, GEPIA2, UALCAN, cBioPortal, Kaplan-Meier plotter, Metascape, and TIMER analysis, to do an in silico exploration of the potential roles of E2Fs in CRC. Read More

Background: High dose chemoradiotherapy offers a curative chance for patients with rectal cancer that are unfit or unwilling to undergo surgical resection, yet its long-term survival and functional outcomes have been rarely investigated.

Methods: Patients with non-metastatic rectal adenocarcinoma who received pelvic radiation for curative intent from April 2006 to July 2017 were retrospectively investigated. Survival rates were analyzed using the Kaplan-Meier method. Read More

Division of Colon and Rectal Surgery, Icahn School of Medicine at Mount Sinai, New York, NY, USA.

Background: As one of the 12 clinical pathways of the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) Masters Program, the Colorectal Pathway intends to deliver didactic content organized along 3 levels of performance (competency, proficiency and mastery) each represented by an anchoring procedure (laparoscopic right colectomy, laparoscopic left/sigmoid colectomy, and intracorporeal anastomosis during minimally invasive (MIS) ileocecal or right colon resection). In this article, the SAGES Colorectal Task Force presents focused summaries of the top 10 seminal articles selected for laparoscopic right colectomy which surgeons should be familiar with.

Methods: Using a systematic literature search of Web of Science, the most cited articles on laparoscopic right colectomy were identified, reviewed, and ranked by the SAGES Colorectal Task Force and invited subject experts. Read More

Endoluminal vacuum-assisted therapy (EVT) has been introduced recently to treat colorectal anastomotic leaks in clinically stable non-peritonitic patients. Its application has been mainly reserved to low colorectal and colo-anal anastomoses. The main advantage of this new procedure is to ensure continuous drainage of the abscess cavity, to promote and to accelerate the formation of granulation tissue resulting in a reduction of the abscess cavity.

Around 10% to 16% of colorectal cancer patients have a pathogenic variant in a cancer susceptibility gene. Some of these variants are in cancer genes that are associated with colorectal cancer while others are not. The hereditary colorectal cancer syndromes can be divided into two major categories, the nonpolyposis and the polyposis conditions. Read More

Rectal cancer is an aggressive subtype of colon cancer with inferior outcomes in terms of disease-free and overall survival. Localized rectal cancer should be managed surgically. For stage II and III rectal cancer, neoadjuvant radiation, either as long-course chemoradiotherapy with a sensitizing fluoropyrimidine or short-course radiation, should be offered in all cases.

Background: Recent studies have indicated the potential benefit of intraoperative near-infrared fluorescence imaging (NIR-FI) with indocyanine green in reducing early anastomotic leakage in colorectal surgery. Nonetheless, whether NIR-FI is effective in reducing structural sequelae of anastomotic leakage (SSAL) remains unclear. The aim of the present study was to investigate the impact of NIR-FI on SSAL after laparoscopic intersphincteric resection (ISR) of malignant rectal tumors. Read More
