Intraductal papillary mucinous neoplasm of pancreas: Clinicopathological features and long-term survival after surgical resection.

Introduction: Intraductal papillary mucinous neoplasm (IPMN) of the pancreas can progress from low-grade dysplasia to high-grade dysplasia and invasive carcinoma.

Methods: In this single-center retrospective series, we analyze the clinicopathological features and long-term follow up of patients who underwent pancreatic resection for IPMN, from January 2009 to December 2019.

Results: 31 patients were diagnosed with IPMN: 9 males and 22 females.

Distal pancreatectomy: experience in a National Hospital.

Aims: To compare the short-term outcomes of patients undergoing open DP (ODP) and laparoscopic DP (LDP); and to analyze the association between the section site of the pancreas and pancreatic fistula.

Materials And Methods: Clinical, perioperative, and histopathologic data of patients who underwent ODP and LDP between 2009 and 2019 were retrospectively analyzed.

Results: 70 patients were included.

[Colorectal synchronism: ascending colon adenocarcinoma and small-cell neuroendocrine carcinoma of the rectum].

Colorectal cancer (CRC) is the third most frequent cancer in the world and the second cause of death of neoplastic origin. Synchronism in CCR is approximately 3-6%. The gastrointestinal tract is the most frequent place where neuroendocrine neoplasms (NNE) settle and a special type of these neuroendocrine carcinomas (CNE) are rare.

[Clinical significance of the presence of granulomas in Crohn's disease].

Unlabelled: Epithelioid granuloma is a characteristic histological feature of Crohn's disease (CD), but their significance with respect to the severity and progression of the disease is still uncertain.

Objective: To evaluate the clinical characteristics of CD patients in relation to the presence or not of granulomas in histological findings.

Materials And Methods: An observational, descriptive, retrospective study in patients diagnosed with CD from January 2004 to December 2019 in the gastroenterology department of the Guillermo Almenara Irigoyen National Hospital, Lima-Peru.

[Clinical-pathological characteristics and endoscopic management of colonic sessile serrated lesions in a reference hospital in Lima - Peru].

Unlabelled: Colorectal cancer (CRC) is one of the most frequent worldwide. Approximately one third of cases originate from the serrated pathway of carcinogenesis, with colonic sessile serrated lesions (SSL) being the main cause of interval CRC.

Objective: To evaluate the clinical, endoscopic, histological characteristics and endoscopic management of colonic LSS.

[Obstructive ictericia by neuroma of amputation of via biliar. Case report].

Neuromas of the bile duct develop from the sympathetic and parasympathetic nerve fibers that surround the wall of the bile duct. A 44-year-old woman with a history of conventional cholecystectomy six months prior to hospital admission attended emergency due to obstructive jaundice that lasted 15 days. In the imaging studies, the presence of a mass at the level of the bile ducts is considered, considering the diagnosis of a malignant neoplasm.

[Characteristics of pancreatic mucinous cystic neoplasm in patients treated at a National Hospital in Peru].

In order to analyze the clinical, pathological, and surgical characteristics of pancreatic mucinous cystic neoplasm (MCN), an analysis of the patients from the Pancreas, Spleen, and Retroperitoneal Surgery Service of the Guillermo Almenara Irigoyen National Hospital in Lima, Peru, was performed from January 2009 to October 2018. The presence of ovarian stroma was used as a diagnostic criterion for MCN. From ten patients with an average age of 47.

[Evaluation of endoscopic and histological activity as predictors of clinical relapse in ulcerative colitis].

Unlabelled: Ulcerative colitis is a chronic inflammatory disease characterized by a recurrent and remitting course. Clinical remission and mucosal healing are the current therapeutic goals in management. The histological remission could be a better objective because of its prognostic impact.

[Hydatid cysts in pancreas: laparoscopic approach].

Unlabelled: Hydatid disease is a parasitic infestation caused by Echinococcus and is endemic in many areas of the world. Hydatid cysts are commonly located in the liver and lung. Pancreas affection is very rare even in endemic areas.

[Epidemiological and clinical characteristics of inflammatory bowel disease in a tertiary referral hospital in Lima-Peru].

Objective: To identify sociodemographic, clinical, and endoscopic characteristics in patients with inflammatory bowel disease (IBD).

Materials And Methods: The study period was from January 2004 to December 2014. The final diagnosis was determined by clinical gastroenterologists experienced in the diagnosis and management of IBD, based on internationally accepted diagnostic criteria.

[One staged laparoscopic surgery of colon cancer with liver metastasis in the Guillermo Almenara Hospital, Lima, Peru].

We report a patient who was diagnosed sigmoid colon cancer associated with liver metastases in segment III. The patient underwent laparoscopic surgery where the sigmoid colon resection and hepatic metastasectomy were performed in a “one staged” surgical procedure. The pathological results showed moderately differentiated tubular adenocarcinoma in sigmoid colon, tubular adenocarcinoma metastases also in liver.

[Pancreatoduodenectomy for ampullary adenocarcinoma and and re-intervention for ganglinonar recurrency].

A 30 years old woman in the 13 week of her second pregnancy who had severe anemia, upper gastrointestinal bleeding and weight loss. She was given the endoscopic diagnosis of a well differentiated ampullary adenocarcinoma. She underwent a pancreato duodenectomy during the 16 week of pregnancy without complications.

[Intraductal papillary mucinous neoplasms of the pancreas in Hospital Nacional Guillermo Almenara Irigoyen, Lima, Peru].

Objective: To analyze retrospectively the clinical, radiologic and pathologic features as well as the surgical results of the patients with diagnosis of intraductal papillary mucinous neoplasms of the pancreas (IPMN).

Materials And Methods: Patients with diagnosis of IPMN who underwent pancreatectomy were identified from January 2006 to September 2013, using the prospective data base of the Pancreas, Spleen and retroperitoneum HNGAI service.

Results: A total of 11 patients were found (9 females and 2 males).
