Management of large-size retrorectal gastrointestinal stromal tumors (GISTs) is complex and challenging from diagnosis to treatment. This may create technical difficulties in surgical access and complete resection of the tumor. The abdominosacral resection has the benefit of improved visualization via the anterior incision, with enhanced exposure of the midrectal area, which makes resecting the tumor completely via the posterior approach easier. We report 2 cases of patients with a retrorectal GIST and neurofibromatosis type 1, one in a 27-year-old woman with a defecation complaint and the other in a 58-year-old woman with a defecation and urination complaint...

Purpose: A cutting seton is used after a partial distal fistulotomy to treat patients with a high exrasphincteric fistula in ano to avoid fecal incontinence and recurrence. In Saudi Arabia, religious practices necessitate complete cleanness, which makes conditions affecting anal continence a major concern to patients affected by an anal fistula. Therefore, we aimed to evaluate the efficiency of the cutting seton in treating a high anal fistula among Saudi Arabians. Methods: Between January 2005 and December 2014, a prospective study was done for 372 Saudi Arabian patients diagnosed as having a high anal fistula and treated with a cutting seton at Al-Ansar General Hospital, Medina, Saudi Arabia...

PURPOSE: Along the invasive margin, colorectal cancer may show distinctive morphologic changes characterized by an asymmetrically attenuating tumor gland with loss of polarity. The author coined the term 'gland attenuation (GA)' for these peculiar changes. The aims of this study were to compare the immunoreactivity of the epithelial-mesenchymal transition (EMT) markers E-cadherin and β-catenin and thus determine whether EMTs occurs at tumor budding (TB) or GA sites and to assess the association of TB and/or GA levels with clinicopathological parameters and prognosis...

PURPOSE: Revolutions have occurred over the last 3 decades in the management of patients with colorectal cancer. Most advances were in rectal cancer surgery, especially after the introduction of the total mesorectal excision (TME) by Heald. However, no parallel advances regarding colon cancer surgeries have occurred. In 2009, Hohenberger introduced a new concept trying to translate the survival advantages of TME to patients with colon cancer. This relatively new concept of a complete mesocolic excision (CME) with central vascular ligation (CVL) in the management of patients with colon cancer represents an evolution in operative technique...

PURPOSE: Obstructive ileocolitis is an ulcero-inflammatory condition which typically occurs in the ileum or colon proximal to an obstructing colorectal lesion. If left unresolved, it often leads to intestinal perforation. We present a matched case control study of patients with obstructive ileocolitis caused by colorectal cancer to determine if any factors can predict this condition. METHODS: This is a retrospective review of 21 patients with obstructive colorectal cancer and histologically proven obstructive ileocolitis from 2005 to 2015 matched for age and sex with 21 controls with obstructing colorectal cancer without obstructive ileocolitis...

The aim of this review is to evaluate the outcomes after an intersphincteric resection (ISR) for patients with low-lying rectal cancer. Reports published in the literature regarding surgical, oncological, and functional outcomes of an ISR were reviewed. The morbidity after an ISR was 7.7%-32%, and anastomotic leakage was the most common adverse event. Local recurrence rates ranged from 0% to 12%, 5-year overall survival rates ranged from 62% to 92%, and rates of major incontinence ranged from 0% to 25.8% after an ISR...

Colorectal large-cell neuroendocrine carcinomas (NECs) are extremely rare and have very poor prognosis compared to adenocarcinomas. A 74-year-old man presented with abdominal pain, diarrhea and hematochezia. The histopathologic report of colonoscopic biopsy performed at a local clinic was a poorly differentiated carcinoma. An abdominopelvic computed scan revealed irregularly enhanced wall thickening at the sigmoid colon with regional fat stranding and lymphnode enlargement. He underwent a laparoscopic high anterior resection with selective peritonectomy for peritoneal carcinomatosis, intraoperative peritoneal irrigation chemotherapy, and early postoperative intraperitoneal chemotherapy for 5 days...

Toxocara canis is an important roundworm of canids and a fearsome animal parasite of humans. Human infections can lead to syndromes called visceral larva migrans (VLM), ocular larva migrans, neurotoxocariasis, and covert toxocariasis. VLM is most commonly diagnosed in children younger than 8 years of age, but adult cases are relatively frequent among those infected by ingesting the raw tissue of paratenic hosts in East Asia. This research reports the case of a 59-year-old man with sigmoid colon cancer, who visited our institution for surgery...

Although toothpick ingestion is rare, it can lead to fatal complications in the gastrointestinal tract. Diagnosing toothpick ingestion is difficult because most patients do not recall swallowing one. We report 2 cases of toothpick-ingestion-induced colon injury, mimicking diverticulitis. The first patient was a 47-year-old male who had received conservative treatment under the impression of his having diverticulitis in the cecum. Ultrasonography revealed a linear foreign body in the right lower abdomen; a subsequent laparoscopic examination revealed inflammation around the cecum, but no evidence of bowel perforation...

PURPOSE: Although numerous procedures have been proposed for the treatment of patients with a rectal prolapse, the most effective operation has not yet been established. Minimal rectal mobilization can prevent constipation; however, it is associated with increased recurrence rates. We describe our novel method for a laparoscopic posterolateral rectopexy, which includes rectal mobilization with a posterior-right unilateral dissection, suture fixation to the sacral promontory with a polypropylene mesh (Optilene), and a mesorectal fascia propria that is as wide as possible...
