Tumor size, tumor location, and antitumor inflammatory response are associated with lymph node size in colorectal cancer patients.

Lymph node size affects lymph node retrieval in surgical specimen and is used as criterion for pre-operative radiological estimation of metastatic disease. However, factors determining lymph node size remain to be established. Therefore, the association between lymph node size and presence of metastatic cancer deposits as well as different primary tumor characteristics was analyzed in a prospective cross-sectional study.

Metachronous gallbladder metastasis from renal cell carcinoma-a rare clinical manifestation.

Renal cell carcinoma (RCC) represents a rare tumor entity accounting for approximately 3 % of all malignancies in the adult population. Approximately 30 % of all patients suffering from RCC develop metastases after nephrectomy and another 30 % of patients suffer from synchronous metastases at the date of diagnosis. Gallbladder metastases represent an extremely rare clinical condition and up to date there are only 35 published cases of gallbladder metastasis from RCC.

Diverting ileostomy versus no diversion after low anterior resection for rectal cancer: A prospective, randomized, multicenter trial.

Background: This study sought to determine whether a protective diverting ileostomy improves short-term outcomes in patients with rectal resection and colonic J-pouch reconstruction for low anastomoses. Criteria for the use of a proximal stoma in rectal resections with colonic J-pouch reconstruction have not been defined sufficiently.

Methods: In a multicenter prospective study, rectal cancer patients with anastomoses below 8 cm treated with low anterior resection and colonic J-pouch were randomized to a defunctioning loop ileostomy or no ileostomy.

Surgical Management of Duodenal Gastrointestinal Stromal Tumors: A Case Report.

Gastrointestinal stromal tumors (GISTs) represent the most common mesenchymal tumor entity of the gastrointestinal tract. In fewer than 5% of cases, primary GISTs are located in the duodenum. Surgery represents the treatment of choice for localized tumor disease and remains challenging in GISTs located at the duodenum.

Uncommon conditions in surgical oncology: acute abdomen caused by ileocolic intussusception.

Background: Bowel intussusception represents an infrequent and challenging condition in adult patients. Preoperative diagnosis and treatment strategies often remain difficult especially in emergency patients. Primary reduction of intussusception before surgical resection is discussed controversially in adult patients and at the moment there is no consensus about the best treatment in literature.

Tumor regression grading after preoperative chemoradiotherapy for locally advanced rectal carcinoma revisited: updated results of the CAO/ARO/AIO-94 trial.

Purpose: We previously described the prognostic impact of tumor regression grading (TRG) on the outcome of patients with rectal carcinoma treated with preoperative chemoradiotherapy (CRT) in the CAO/ARO/AIO-94 trial. Here we report long-term results after a median follow-up of 132 months.

Patients And Methods: TRG after preoperative CRT was determined in 386 surgical specimens by the amount of viable tumor cells versus fibrosis, ranging from TRG 4 (no viable tumor cells) to TRG 0 (no signs of regression).

Impact of postoperative complications on long-term survival after resection for rectal cancer.

Background: The relevance of type and severity of postoperative complications after curative resection for rectal cancer on survival and recurrence rates is a matter of controversy.

Objective: The aim of this study was to investigate the impact of postoperative complications on long-term outcome after resection for rectal cancer.

Design: This study is a retrospective analysis of prospectively collected data.

Influence of body mass index on postoperative complications after rectal resection for carcinoma.

Objectives: The influence of obesity on postoperative complications after various surgical interventions remains controversial. The aim of this study was to evaluate the impact of overweight and obesity on the occurrence of postoperative complications for patients undergoing elective resection for rectal carcinoma.

Methods: We conducted a retrospective data analysis of 676 patients undergoing surgical treatment for rectal carcinoma.

Natural orifice transluminal endoscopic surgery in surgical oncology: analysis of indications and feasibility in cancer patients.

Background/aims: Natural orifice endoscopic surgery (NOTES) is an emerging technique that has been postulated as a promising alternative to laparoscopy in the field of minimal invasive surgery. Until now appropriate indications, safe access routes and general feasibility of this approach have not been defined exactly in surgical oncology.

Methodology: A total of 474 patients undergoing cancer surgery were analyzed regarding possible applications of transluminal endoscopic surgery.

Influence of pT3 subgroups on outcome of R0-resected colorectal tumors.

Objective: Evaluate whether depth of infiltration within T3 colorectal tumors influences long-term oncologic outcome.

Patients And Methods: Patients with stage pT3 colon and rectal tumors were divided into four subgroups according to the depth of infiltration. The influence on overall and disease-free survival was tested for each subgroup and compared in univariate and multivariate analyses.

Perineal colostomy with spiral smooth muscle graft for neosphincter reconstruction following abdominoperineal resection of very low rectal cancer: long-term outcome.

Background: To avoid abdominal colostomy and improve quality of life, several types of anorectal reconstruction following abdominoperineal resection have been proposed. The aim of this study was to assess functional results and the quality of life of patients with very low rectal cancer after abdominoperineal resection and neosphincter reconstruction by perineal colostomy with a colonic muscular cuff.

Patients And Methods: Twenty-seven patients who had undergone neosphincter reconstruction with a perineal spiral cuff plasty after abdominoperineal resection were included in a retrospective study to evaluate long-term outcome.

Heterotopic pancreatic tissue in the cystic duct: complicating factor or coexisting pathology.

The case of a 75-year-old female suffering from recurrent abdominal pain and nausea is presented. Ultrasound showed gallstones without inflammation of the gallbladder. The patient underwent laparoscopic cholecystectomy and her symptoms resolved.

The effect of endoscopic treatment on healing of anastomotic leaks after anterior resection of rectal cancer.

Background: Despite surgical advances, anastomotic leaks remain a major complication after rectal resection. Endoscopic techniques are increasingly used as an alternative or in addition to conventional operative therapy of anastomotic leakage. We have analyzed the impact of endoscopic treatment on the outcome of patients with leaks after resection of rectal cancer.
