Multiple colorectal liver metastases resection can offer long-term survival: The concept of a chronic neoplastic disease.

Background: Resection for colorectal liver metastases has evolved significantly and, currently, there are no limits to the number of resected nodules. This study aimed to evaluate the outcomes and prognostic factors after liver resection for patients with ≥4 colorectal liver metastases, emphasizing long-term survival.

Methods: The study population consisted of 137 patients with ≥4 colorectal liver metastases out of a total of 597 patients with colorectal liver metastases who underwent curative intent liver resection from January 2010 to July 2019 in a single hepatobiliary center.

Isolated Splenic Metastases from Renal Cell Carcinoma 11 Years after Surgery.

Splenic metastases are rare and usually occur in cases of disseminated disease. We report a case of a patient who had isolated splenic metastases with a previous history of left nephrectomy due to a renal cell carcinoma 11 years before. The aim of this report is to describe the case and review the literature of isolated splenic metastases due to renal carcinoma.

A rare case of idiopathic congenital megaduodenum in adult misinterpreted during childhood: case report and literature review.

Intestinal malformations are common disorders in newborn and favorable outcomes have been reported for such conditions. Although, if the patient is treated in a not experienced center, misinterpretation of the clinical and radiological findings may lead to errors in treatment and possible complications in adulthood. We report a case of a congenital megaduodenum which was misinterpreted as an intestinal malrotation resulting in late complications.

Downstaging and resection after neoadjuvant therapy for fibrolamellar hepatocellular carcinoma.

Fibrolamellar hepatocellular carcinoma (FLHCC) is a rare malignant liver neoplasm, commonly observed in adolescents and young adults of both genders. The disease is more common in Caucasians and in patients without a prior history of liver disease. The best treatment option is a surgical resection associated with liver hilum lymph node dissection.

Rare cause of abdominal incidentaloma: Hepatoduodenal ligament teratoma.

The occurrence of a hepatoduodenal ligament teratoma is extremely rare, with only a few cases reported in the literature. This case report describes the discovery of a hepatoduodenal ligament lesion revealed during abdominal ultrasonography for cholelithiasis-related abdominal pain in a 27-year-old female. Cross-sectional imaging identified a 5 cm × 4 cm heterogeneous mass of fat tissue with irregular calcification located in the posterior-superior aspect of the head of the pancreas.

Reduced population of interstitial cells of Cajal in Chagasic megacolon.

Background/aims: In Chagasic megacolon, there is a reduction in the population of interstitial cells of Cajal. It was aimed to evaluate density of Cajal cells in the resected colon of Chagasic patients compared to control patients and to verify possible association between preoperative and postoperative bowel function of megacolon patients and cell count.

Methodology: Sixteen megacolon patients (12 female; mean age 54.

Surgical outcomes after preceptored laparoscopic colorectal surgery: results of a Brazilian preceptorship program.

Background/aims: Safety of laparoscopic colectomy education methods remains unknown. This study aimed at comparing the outcomes of patients undergoing preceptored laparoscopic colectomy with patients operated on by the same preceptor.

Methodology: A prospective analysis of 30 pre-ceptored operations performed by nine surgeons (PD group) between 2006 and 2008 was conducted.

Stapled hemorrhoidectomy vs closed diathermy-excision hemorrhoidectomy without suture-ligation: a case-controlled trial.

Background/aims: We compared stapled hemorrhoidectomy to closed diathermy-excision hemorrhoidectomy without suture-ligation regarding postoperative pain, complications and long-term efficacy.

Methodology: A series of 108 patients had indication for stapled hemorrhoidectomy. Patients who underwent stapled hemorrhoidectomy (76) were compared to patients submitted to closed diathermy-excision hemorrhoidectomy (32) due to non-insurance cover.

Conventional approach x laparoscopic abdominoperineal resection for rectal cancer treatment after neoadjuvant chemoradiation: results of a prospective randomized trial.

Objective: The aims of this study were to evaluate the safety and efficacy of laparoscopic abdominoperineal resection compared to conventional approach for surgical treatment of patients with distal rectal cancer presenting with incomplete response after chemoradiation.

Method: Twenty eight patients with distal rectal adenocarcinoma were randomized to undergo surgical treatment by laparoscopic abdominoperineal resection or conventional approach and evaluated prospectively. Thirteen underwent laparoscopic abdominoperineal resection and 15 conventional approach.

[Efficacy of contrast chromoendoscopy of the colon after oral administration of indigo carmine dye].

Introduction: Indigo carmine dye is usually spread directly over the colon in many chromoscopic techniques aiming better visualization of a lesion already detected by conventional colonoscopy. Examination of the colon already stained by oral administration of indigo carmine dye may increase detection of small lesions resulting in higher sensibility of the colonoscopy in diagnosing diminutive lesions.

Objective: Analyze the results regarding the quality of chromoscopic technique and the indigo carmine dye distribution over the colon after oral administration.
