Right hemicolectomy

BACKGROUND: The oncological effectiveness of preoperative radiotherapy for locally advanced colon cancer is unclear. We report a case of pathological complete response in a patient with locally advanced ascending colon cancer after preoperative radiotherapy following failure of chemotherapy. CASE PRESENTATION: A 65-year-old Japanese woman presented with malaise and hematochezia. A computed tomography (CT) revealed a tumor in the ascending colon which seemed to infiltrate the adjacent structures...

Carcinoembryonic antigen (CEA) is still the most widely used tumour marker for gastrointestinal cancer. CEA was originally thought to be a specific marker for colorectal cancer, but it turned out to be a non-specific marker for further studies. CEA levels can be elevated in breast, lung and liver cancers, among others, including medullary thyroid cancer. The authors report a case of a 73-year-old woman who had a right hemicolectomy for an ascending colon adenocarcinoma and showed a persistent elevation in the CEA marker during follow-up...

BACKGROUND: Complete mesocolic excision (CME) has been proposed for colon cancer to improve oncological outcomes. The risks and benefits of laparoscopic CME have not been examined fully. We compared short- and long-term outcomes of CME with a conventional mesocolic excision (non-CME) in laparoscopic right hemicolectomy (RHC) for right-sided colon cancer. METHODS: In total, 115 patients who underwent laparoscopic RHC with stage I-III right-sided colon cancer at Busan Paik Hospital from August 2007 to October 2011 were enrolled in this case-control study...

Background: Appendiceal mucinous tumour (AMT) is a very uncommon disease. We aimed to evaluate preoperative and postoperative characteristics as well as long-term outcomes of patients with appendiceal mucinous adenomas and peritoneal pseudomyxoma (PMP). Methods: A consecutive cohort of patients diagnosed with AMT were included in the study. Tumour recurrence and the development of PMP was diagnosed based on the patients' complaints, physical examination, imaging studies, and biopsy results...

A 90-year-old man was referred to our hospital because of a positive fecal occult blood test. Colonoscopy revealed a lesion with multiple nodules covered with abundant mucus at the hepatic flexure. Computed tomography showed a dilated appendix attached distally to the hepatic flexure. Right hemicolectomy was performed, and the pathological examination revealed a mucinous appendiceal adenocarcinoma infiltrating the hepatic flexure without pseudomyxoma peritonei. The patient is doing well without recurrence 12 months postoperatively...

Locally advancement of right colon cancer to the surrounding organs requiring surgical intervention is an extensive procedure associated with numerous risks. There are not many cases of which this phenomenon may occur. En bloc pancreaticoduodenectomy and resection of involved viscera should be considered for patients who can appropriately undergo this exhaustive surgery. Our objective is to report the experience we had with this patient who underwent an en bloc pancreaticoduodenectomy and right hemicolectomy and review literature...

Objectives: Amoebiasisis a common parasitic infection and fulminant amoebic colitis remains a very rare complication of this disease. The objective of the present study was to find the incidence and outcome of perforation peritonitis due to amoebic colitis in MMIMSR, Mullana, Ambala, India. Material and methods: 200 patients with perforation peritonitis were studied retrospectively, out of which 22 cases had colonic perforation, were selected over a period of five years, between 2012 to 2017, at MMIMSR Mullana...

Cecal diverticulum is a rare clinical condition which may present as acute abdomen through diverticulitis and perforation of diverticulitis. Surgical treatment of cecal diverticulitis has been controversial, with studies recommending options ranging from conservative management with antibiotics alone to aggressive resection. Two cases, one of which was pre- diagnosed with cecal tumor perforation and the other with cecal tumor leading to intestinal obstruction, were urgently operated. To both patients, right hemicolectomy was applied...

Background and Aim: Benchmarking has proven beneficial in improving the quality of surgery. Mortality rate is an objective indicator, of which the 30-day mortality rate is the most widely used. However, as a result of recent advances in medical care, the 30-day mortality rate may not cover overall surgery-related mortalities. We examined the significance and validity of the 30-day mortality rate as a quality indicator. Methods: The present study was conducted on cancer surgeries of esophagectomy, total gastrectomy, distal gastrectomy, right hemicolectomy, low anterior resection, hepatectomy, and pancreaticoduodenectomy that were registered in the first halves of 2012, 2013 and 2014 in a Japanese nationwide large-scale database...

Objective: Nationwide databases are expected to provide critical data to improve medical practice. The present study used such data to develop risk models for clinically important outcomes after right hemicolectomy based on preoperative risk factors. Methods: Japan's National Clinical Database (NCD) identified 38 030 cases of right hemicolectomy in the years 2011 and 2012. These were used to analyze correlations between mortality and eight selected clinical outcomes of interest by Pearson's correlation coefficient ( r )...

Initiating chemotherapy usually requires a delay of more than 4 weeks after surgically resecting colorectal cancer. However, there is little evidence regarding the required delay interval. We have previously reported a pilot study to determine the safety and feasibility of early initiation of chemotherapy after resecting primary colorectal cancer with distant metastases. We aimed to determine the safety and efficacy of early initiation of chemotherapy after resecting colorectal cancer with distant metastases...

BACKGROUND: Efficient hemostatic techniques are essential in laparoscopic surgery for ideal intraoperative and postoperative results. A variety of advanced devices are available for the sealing of major vascular structures. The aim of this study is to assess effectiveness and safety of major vessel sealing with a radiofrequency device during laparoscopic colorectal resections for cancer based on the experience of a single hospital. METHODS: Early outcomes of a consecutive series of patients who received elective laparoscopic colorectal resections for cancer over a 10-year period (January 2008-September 2017) are analyzed...

Cecal bascule is a rare subtype of cecal volvulus where the cecum folds anterior to the ascending colon causing intestinal obstruction. It is a challenging diagnosis to make in the emergency department, as the mobile nature of the cecum leads to a great deal of variation in its clinical presentation. Our discussion of a 78-year-old female who presented with abdominal pain and was found to have a cecal bascule requiring right hemicolectomy, demonstrates how emergency physicians must expand their differential diagnosis for patients reporting signs of intestinal obstruction...

Myeloid sarcoma (MS) is a rare condition that most commonly occurs in the setting of acute myeloidleukaemia (AML) or other chronic myeloproliferative disorders. It presents as an abnormal growth that can develop anywhere in the human body, and its clinical manifestations are often non-specific.We present the case of a patient admitted to the emergency room with bowel obstruction. After careful clinical assessment, she underwent a right hemicolectomy. After a thorough examination of the surgical pathology specimen, including testing a wide array of immunohistochemical markers, the patient was timely diagnosed with MS, allowing for the implementation of the appropriate treatment to achieve complete remission...

BACKGROUND: Inguinal hernias and colorectal cancers are common conditions, but the presentation of a loop of bowel containing cancer within a hernia is rare. Principles of surgery include oncological resection of the involved colonic segment as well as lymphatic drainage. Based on case reports of the last several decades, there have been no reports of a case where the reduction of an inguinoscrotal hernia and oncological colectomy were performed completely laparoscopically. We present the first instance of a completely laparoscopically assisted resection and hernia repair on a patient with T4 ascending colon cancer...

OBJECTIVE: To investigate clinicopathological features and prognostic factors of appendiceal neuroendocrine neoplasms(a-NEN). METHODS: Clinical data of 20 patients diagnosed with a-NEN at Zhongshan Hospital of Fudan University between January 2000 and December 2016 were retrospectively analyzed. Pathological diagnosis was based on the WHO classification criteria of digestive system tumors (2010 edition). Based on the mitotic count and Ki-67 index, a-NENs were divided into grade 1 neuroendocrine tumor (NET G1), grade 2(G2) NET G2) and grade 3 (neuroendocrine carcinoma, NEC)...

This case report describes the development of a rash in a patient admitted with large bowel obstruction secondary to carcinoma of the sigmoid colon. The patient underwent a Hartmann's procedure and right hemicolectomy for a metastatic deposit at the terminal ileum. On postoperative day 3, the patient developed a bullous haemorrhagic rash on the thighs, flanks and abdomen, associated with a sharp drop in platelet count. Suspicion of heparin-induced skin necrosis was raised, and prophylactic enoxaparin was switched to fondaparinux...

PURPOSE: To determine risk factors for early postoperative complications and longer hospital stay after ileocecal resection and right hemicolectomy in a single-center cohort of patients with Crohn's disease (CD). METHODS: A retrospective analysis of the prospectively maintained surgical database for patients with CD at our institution was performed. All consecutive patients operated on between January 2010 and December 2016 were included. RESULTS: A total of 305 patients were included...
