Colorectal obstruction

BACKGROUND/AIM: Colonic stents have been inserted as a bridge to surgery in patients with resectable colorectal cancer, allowing bowel decompression for systemic assessment and better preparation to avoid stoma construction. However, reports of short- and long-term prognoses for elderly patients remain limited. PATIENTS AND METHODS: This retrospective study reviewed 175 consecutive patients who underwent colonic stent insertion for bowel obstruction followed by curative colectomy...

PURPOSE: Self-expandable metallic stent (SEMS) placement is widely used as a bridge to surgery (BTS) procedure for obstructive colorectal cancer. However, evidence regarding the optimal interval between SEMS placement and elective surgery is lacking. METHODS: We retrospectively collected data from patients with BTS between January 2013 and October 2021. Inverse probability treatment-weighted propensity score analyses were used to compare short- and long-term outcomes between the short-interval (SI) and long-interval (LI) groups, using a cutoff of 20 days...

INTRODUCTION: Multiple primary neoplasms (MPN) are rare and can affect any system especially the upper aero-digestive system. They can be simultaneous, synchronous or metachronous. Their management depends on the individual organ system affected and simultaneous resection is possible as shown by T. Suzuki. PRESENTATION OF CASE: We encountered a 77-year-old male who had had malena and constipation for 2 months and on investigation was found to have a rectosigmoid and an esophageal adenocarcinoma as well as a calcified lesion in the brain...

INTRODUCTION AND IMPORTANCE: Acute colonic pseudo-obstruction (ACPO) is an uncommon phenomenon that is especially rare in young patients and can result in bowl ischemia and perforation if left untreated. Furthermore, pneumoperitoneum is almost always a concerning imaging finding and in the context of recent colonic resection may be a sign of anastomotic leakage. CASE PRESENTATION: We describe a case of a young female patient with postpartum ACPO who subsequently underwent a hemicolectomy with colorectal anastomosis...

BACKGROUND: Oncological outcomes of stenting as a bridge to surgery (SBTS) remain a major concern, despite perioperative benefits it offers. This study aims to evaluate the differences in recurrence patterns and survival in patients with non-metastatic, obstructing left sided colon cancers treated by SBTS versus upfront emergency surgery (ES). METHODS: This is a retrospective, single-centre cohort study of 227 consecutive patients with non-metastatic, obstructing left sided colon cancer between 2007 and 2016...

INTRODUCTION: Elderly patients requiring surgical treatment is increasing in Japan, and while surgical treatment is expected to be effective even in the very elderly, there is a lack of evidence for the safety and efficacy of surgical resection due to problems with perioperative management and operative tolerance. We therefore retrospectively examined the short-term and long-term outcomes of colorectal cancer surgery for the very elderly at our hospital. SUBJECTS: The study included 14 cases of colorectal cancer in the very elderly who underwent radical resection at our hospital between January 2010 and March 2020...

BACKGROUND: Surgical treatment of recurrent rectal prolapse is associated with unique technical challenges, partly determined by the surgical approach utilized for the index operation. Success rates are variable and data to determine the best approach in patients with recurring prolapse are lacking. OBJECTIVE: To assess current surgical approaches to patients with prior rectal prolapse repairs and to compare short-term outcomes of de novo and redo procedures, including recurrence of rectal prolapse...

A granulocytic sarcoma is an unusual tumor outside of bone marrow. It is composed of immature cells of the granulocytic cell line. We present a rare case of a 76-year-old male with a history of myelodysplastic syndrome who presented with a large bowel obstruction secondary to lesions at the cecum and transverse colon. He underwent exploratory laparotomy with extended right hemicolectomy. A pathological examination confirmed a granulocytic sarcoma as the cause of the obstruction.

Spigelian hernias are an uncommon type of primary ventral hernia and are defined as a defect in the Spigelian aponeurosis (fascia). Herein, we present an uncommon case of Spigelian hernia to highlight the potential complications of these hernias and the need for surgical management. This is a case report of an 86-year-old gentleman presenting post-fall with an acute rib fracture and an incidental Spigelian hernia seen on a CT trauma pan scan. The Spigelian hernia surgical treatment was planned for elective management due to the anesthetic risks associated with an elderly patient and acute rib fractures...

Colonic stent placement is a commonly used bridging strategy for surgery in patients with obstructive colorectal cancer. The procedure involves the placement of a self-expandable metallic stent (SEMS) across the obstructive lesion to restore intestinal patency and alleviate the symptoms of obstruction. By allowing patients to receive surgery in a planned and staged manner with time for preoperative optimization and bowel preparation, stent placement may reduce the need for emergency surgery, which is associated with higher complication rates and poorer outcomes...

INTRODUCTION: Iliopsoas abscesses (IPAs) associated with bowel obstruction due to colon cancer are rare, and there is no consensus regarding treatment strategies. PRESENTATION OF CASE: A 63-year-old man presented with swelling and pain in the right iliac region. Imaging studies revealed an IPA expanding from the psoas major muscle and retroperitoneal space subcutaneously around the right ilium. After percutaneous drainage, the patient developed bowel obstruction secondary to colon cancer...

ABTRACT: BACKGROUND: When constructing an ileal pouch-anal anastomosis (IPAA), the rectal cuff should ideally be 1-2 cm long to avoid subsequent complications. METHODS: We identified patients from our IBD center who underwent redo IPAA for a long rectal cuff. Long rectal cuff syndrome (LRCS) was defined as a symptomatic rectal cuff ≥ 4 cm. RESULTS: Forty patients met the inclusion criteria: 42.5% female, median age at redo surgery 42...

Alpha-fetoprotein (AFP) is commonly produced by hepatocellular carcinoma and yolk sac tumors, while AFP in colorectal cancer (CRC) is a rare association. We report a case of a patient with primary AFP-producing CRC, which was successfully treated with surgery and adjuvant chemotherapy. This case highlighted the importance of recognizing a case of AFP-producing CRC.  This case report discussed a 59-year-old male who had a history of hepatitis B infection, with two months of intermittent fresh per rectal bleeding...

Since the insurance coverage of colorectal stents for bowel obstruction due to colorectal cancer in 2012, the use of colorectal stenting for palliation has rapidly spread. We report a case of ascending colon cancer in which a colorectal stent was placed for palliation, but the stent was reimplanted due to obstruction, followed by radical resection. The patient was a 92- year-old woman who was brought to the emergency room at the age of 90 years with repeated vomiting and abdominal pain, and was diagnosed as colorectal cancer ileus caused by ascending colon cancer, and a colorectal stent was inserted...

BACKGROUND: Over the past decade, the use of stent placement as a bridge to surgery (BTS) has emerged as an alternative to emergency surgery for patients with (OCRC). However, the optimal surgical approach remains indeterminate. This study seeks to evaluate the safety and feasibility of a combined treatment modality involving stent placement and laparoscopic surgery for OCRC presenting with malignant obstruction. METHODS: A comprehensive search of PubMed, Cochrane Library, EMBASE, Web of Science, and ClinicalTrials...

Drain-site recurrence following colorectal cancer resection is a rare event and is described in few case reports. The majority of these reports are following minimally invasive surgery. This report describes a case of an isolated drain-site recurrence of primary colorectal cancer in a male patient in his 50s. He previously underwent an open right hemicolectomy and segmental small bowel resection for an obstructing ileocaecal valve adenocarcinoma. This was followed by adjuvant chemotherapy. Two years into surveillance, a redo ileocolic resection was performed for an anastomotic recurrence...

BACKGROUND: Radiographic imaging of abdomen and pelvis plays an important role in the diagnosis and management of ileal pouch disorders with modalities including computed tomography, magnetic resonance imaging, contrasted pouchography, and defecography. OBJECTIVES: A systematic review of the literature was performed and applications of cross-sectional imaging, pouchography, defecography, and ultrasonography are described. DATA SOURCES: PubMed, Google Scholar, and Cochrane database...

BACKGROUND: Intra-abdominal desmoplastic small round cell tumor (IDSRCT) is a rare entity (0.2-0.74 cases per million people per year), which predominantly occurs in young men. It may present as an abdominal mass with pain, distention, and constipation. IDSRCT has a very poor prognosis, with 5-year overall survival estimated at 15%-30%. Diagnosis is made with tissue biopsy. CASE DESCRIPTION: We present a case of a 28-year-old man with a history of schizophrenia and depression who presented to an emergency room (ER) in November 2022 with constipation and pelvic pain...

OBJECTIVE: By constructing a predictive model using machine learning and deep learning technologies, we aim to understand the risk factors for postoperative intestinal obstruction in laparoscopic colorectal cancer patients, and establish an effective artificial intelligence-based predictive model to guide individualized prevention and treatment, thus improving patient outcomes. METHODS: We constructed a model of the artificial intelligence algorithm in Python. Subjects were randomly assigned to either a training set for variable identification and model construction, or a test set for testing model performance, at a ratio of 7:3...
