Initial case series experience with robotic-assisted transanal minimally invasive surgery performed with da Vinci single-port system for the excision of rectal cancer.

Background: Transanal minimally invasive surgery (TAMIS) is widely used for rectal lesion excision. Robot-assisted TA TAMIS (R-TAMIS) may improve surgical ergonomics. The introduction of the da Vinci Single-Port (SP) robot, designed for endoluminal surgery, has brought new possibilities.

Ruptured splenic artery aneurysms in pregnancy and usefulness of endovascular treatment in selective patients: A case report and review of literature.

Background: The rupture of a splenic artery aneurysm (SAA) in pregnancy is an uncommon condition. However, it is associated with high mortality rates in pregnant women and fetuses even after surgical treatment. Though the endovascular treatment of SAAs is currently preferred as it can improve the outcomes even in emergent cases, the endovascular treatment of a ruptured SAA during pregnancy has not been reported until date.

Superior mesenteric artery syndrome treated successfully by endoscopy-assisted jejunal feeding tube placement.

We report the case of a 31-year-old man with superior mesenteric artery syndrome after reoperation due to postoperative complications from rectal cancer. Although initial total parenteral nutrition (TPN) therapy failed, he underwent endoscopy-assisted feeding tube placement without complications instead of surgery. After 2 weeks of dual feeding (enteral feeding and TPN), he improved, gaining 6 kg; and an oral diet was advanced.

Skeletal muscle gauge as a prognostic factor in patients with colorectal cancer.

Background: Although skeletal muscle index (SMI) and radiodensity (SMD) are well-known prognostic factors, the clinical impact of the integrated measure, known as skeletal muscle gauge (SMG), has been limited in patients with colorectal cancer (CRC).

Patients And Methods: A total of 727 and 268 patients with CRC at two tertiary centers were included and allocated into the training and test sets, respectively. Preoperative slice computed tomography images of the third lumbar area were evaluated for SMI and SMD.

Severe abdominopelvic actinomycosis with colon perforation and hepatic involvement mimicking advanced sigmoid colon cancer with hepatic metastasis: a case study.

Background: Actinomycosis is a rare chronic invasive disease caused by Actinomyces spp. Although abdominopelvic actinomycosis, which involves the colon and the pelvic organs extensively, has been frequently reported, abdominopelvic actinomycosis presenting with colon perforation and hepatic involvement concurrently has yet to be reported.

Case Presentation: A 55-year-old woman presented at the emergency room with squeezing epigastric pain.

Evaluating the Feasibility of Single Incision Laparoscopic Appendectomy Performed by a Resident Based on Propensity Score Matching.

Purpose: Conventional laparoscopic appendectomy (CLA) has been considered the standard for the treatment of acute appendicitis. Recently, single incision laparoscopic appendectomy (SILA) has become an alternative option. There are few reports on the results of SILA performed by residents during the training period.

Poor prognostic factors in patients who underwent surgery for acute non-occlusive ischemic colitis.

Introduction: Ischemic colitis (IC) is a disease with high postoperative morbidity and mortality. Knowledge of the risk factors for postoperative mortality could be helpful in clinical decision making and in optimizing postoperative treatment.

Methods: From a prospective database, we conducted a retrospective medical record review of 50 patients who underwent surgery for IC between 2003 and 2011 at our institution.

The effectiveness of endoscopic submucosal resection with a ligation device for small rectal carcinoid tumors: focused on previously biopsied tumors.

Purpose: To evaluate the effectiveness of endoscopic submucosal resection with a ligation device (ESMR-L) on histologic complete resection for the treatment of small rectal carcinoid tumors in comparison with the treatment with endoscopic mucosal resection (EMR) alone.

Methods: Thirty-five patients with small rectal carcinoid tumors were enrolled prospectively for ESMR-L, and we retrospectively reviewed 74 carcinoid tumor patients who underwent EMR. The comparison between ESMR-L and EMR groups was analyzed including endoscopic and histologic complete resection and complications after resection.

Oncologic outcomes and proper surveillance after local excision of rectal cancer.

Purpose: The aim of this study was to analyze oncologic outcomes after transanal local excision (LE) to ensure adequate surveillance of recurrence in order to treat with curative intent.

Methods: Between January 2000 and June 2009, 102 patients who underwent transanal LE for rectal adenocarcinoma were retrospectively reviewed.

Results: Of the 102 patients, 53 (52.

Casein kinase 2 regulates the mRNA-destabilizing activity of tristetraprolin.

Tristetraprolin (TTP) is an AU-rich element-binding protein that regulates mRNA stability. We previously showed that TTP acts as a negative regulator of VEGF gene expression in colon cancer cells. The p38 MAPK pathway is known to suppress the TTP activity.
