Resección duodenal distal: análisis de nuestra experiencia con una cirugía infrecuente / Distal duodenal resection: analysis of our experience with infrequent surgery

Resumen Introducción: La resección duodenal distal (RDD) es una técnica quirúrgica compleja e infrecuente usada para el tratamiento de patologías duodenales o extraduodenales, que no comprometen la papila duodenal mayor, siendo su indicación más frecuente la patología neoplásica. Objetivo: Dar a conocer nuestra experiencia con esta técnica quirúrgica. Materiales y Método: Serie de pacientes sometidos a RDD entre 2009-2020 en el Hospital Clínico UC. Resultados: Total 12 pacientes, mediana de edad 56 años. Diagnóstico preoperatorio: tumores primarios duodenales (4), tumores con compromiso duodenal por contigüidad (5) y patologías de urgencia (3). El abordaje fue abierto en 9 pacientes y laparoscópico en 3 (1 caso convertido). En 9 pacientes se resecó D3-D4, en 1 paciente incluyó parte de D2 y en 2, sólo D4. La anastomosis duodenoyeyunal fue manual en 10 casos, todas con ascenso transmesocólico del asa yeyunal. Hubo 33% (n: 4) de morbilidad, todos Clavien Dindo II y 8% de mortalidad (n: 1). No hubo filtración de la anastomosis duodenoyeyunal. En el seguimiento ninguno presentó complicaciones y 4 pacientes fallecieron por progresión oncológica. Conclusión: La principal indicación quirúrgica fue patología neoplásica y en nuestra serie no hubo morbilidad mayor ni filtración anastomótica.

Introduction: Distal duodenal resection is a complex and infrequent surgical technique used for the treatment of duodenal or extraduodenal pathologies that do not compromise the greater duodenal papilla, the most frequent indication being the neoplastic cause. Aim: To publicize our experience with this surgical technique. Materials and Method: Series of patients undergoing a distal duodenal resection between 2009-2020 at the UC Clinical Hospital. Results: Total 12 patients, median age 56 years. Preoperative diagnosis: primary duodenal tumors (4), tumors with duodenal involvement due to contiguity (5), and emergency pathologies (3). The approach was open in 9 patients and laparoscopic in 3 (1 converted). D3-D4 was resected in 10 patients, 1 included part of D2 and 2 only D4. The duodenojejunal anastomosis was manual in 10 cases, all with transmesocolic ascending of the jejunal loop. There were 33% (n: 4) morbidity, all Clavien Dindo II, and 8% mortality (n: 1). There was no leakage of the duodenojejunal anastomosis. During followup, none presented complications and 4 patients died of oncological progression. Conclusion: The main surgical indication was neoplastic pathology and in our series, there was no major morbidity or anastomotic leak.

Malignant gastroduodenal obstruction: An endoscopic approach

Malignant gastric outlet obstruction describes a constellation of symptoms that can result as a common endpoint from a variety of primary tumours, particularly those of the upper gastrointestinal tract and pancreas. Affected patients face a dismal, undignified and rapid decline in health secondary to malnutrition, dehydration and constant nausea with associated vomiting. Palliative treatment has traditionally involved a gastrojejunostomy—a major undertaking given the functional status of these patients. More recent advances in the endoscopic placement of metal stents to relieve obstruction have clear benefits over the surgical method. We look at the factors involved in patient selection, the techniques and considerations involved in stent deployment and the potential complications associated with this method.

A Case of Malignant Intraductal Papillary Mucinous Neoplasm of the Pancreas with Duodenal Adenocarcinoma / 대한소화기내시경학회지

Intraductal papillary mucinous neoplasm of the pancreas (IPMN) is a precancerous lesion with a well-described adenocarcinoma sequence. The rate of progression of IPMN appears to be very slow; however, patients with IPMN may be at increased risk for extrapancreatic malignancies. A 55-year-old female was diagnosed with IPMN of the pancreas and a duodenal polyp in 2004. After an approximate 3 year loss to follow-up, she was readmitted for managing abdominal pain and underwent Whipple's operation. Herein, we report a case of a patient with malignant IPMN accompanied by duodenal adenocarcinoma arising from a duodenal polyp.

Efficacy and Long-Term Outcome of Endoscopic Treatment of Sporadic Nonampullary Duodenal Adenoma

BACKGROUND/AIMS: Endoscopic resection has proven to be a safe and effective alternative to surgery for duodenal adenomas. However, few data are available on the adequacy of resection and long-term outcomes. This study evaluated the efficacy and longterm endoscopic findings in a cohort of Korean patients who underwent endoscopic mucosal resection (EMR) of sporadic duodenal adenomas. METHODS: Seventeen patients with nonampullary duodenal adenomas without familial polyposis syndrome and who were treated by EMR between January 2001 and December 2007 were evaluated retrospectively. Their management, follow-up, and outcomes were reviewed. RESULTS: In total, seventeen lesions were removed from EMR in 17 patients (mean age, 59.3 years; 6 women, 11 men). The mean size of the tumors was 15.1 mm (median, 13 mm, range, 8-27 mm). Of these 17 adenomas, 16 adenomas were tubulous and 1 was tubulovillous. The EMR was performed successfully in all 17 patients in a single session. After a median follow-up period of 29 months (range, 13-72 months), all patients remained in remission. One patient had bleeding at the site of the EMR. There were no perforations after the EMR. CONCLUSIONS: EMR for sporadic duodenal adenomas seemed to be a safe and effective treatment modality.

Gangliocytic Paraganglioma

Gangliocytic paraganglioma (GP) is a rare benign tumor that is usually seen in the duodenum. It shows unique histologic features that are composed of a carcinoid or paraganglioma-like appearance, ganglion cells, and Schwann cells. The common presenting symptoms are abdominal pain, gastrointestinal bleeding and obstruction. The lesion can sometimes be asymptomatic and they are discovered incidentally. We experienced a case of incidentally found GP in a 73 year-old-man who had a colon cancer with liver metastasis. During the preoperative workup, a submucosal tumor was found in the duodenal papilla. The frozen diagnosis of the duodenal mass was GP, which was confirmed by the permanent sections and immunohistochemical staining. Pathologists should be alert to recognize and diagnose this rare, but benign disease, especially in the patient suffering with gastrointestinal cancer.

Metastasis to the Thigh Skeletal Muscle from an Adenocarcinoma of the Duodenum / Journal of the Korean Cancer Association, 대한암학회지

Skeletal muscle is one of the most unusual metastatic sites for any malignancy. Duodenal cancer is extremely rare, and no cases of skeletal muscle metastasis from duodenal cancer have been reported. We report here in a case of metastasis to the skeletal muscle of the left thigh from duodenal cancer. Our patient was a 47-year-old man, exhibiting a painful mass in the posterior aspect of his left thigh over a 4 month period. An imaging study, and a biopsy, revealed a duodenal adenocarcinoma metastasize to the skeletal muscle. The patient refused chemotherapy and has followed up for 4 months.
