RESUMO
INTRODUCTION AND IMPORTANCE: Minimally invasive esophagectomy has emerged as the established standard for treating esophageal cancer. The gastric graft is usually placed in the posterior mediastinum or the retrosternal tunnel for reconstruction. Hiatal hernia occurrence is more common in the posterior mediastinal reconstruction and is more frequently observed in laparoscopic compared to open approach. On the other hand, retrosternal hernia is a rare complication that deserves greater attention, considering the increasing popularity of retrosternal reconstruction in esophageal cancer treatment. CASE PRESENTATION: We present the case of a 55-year-old male patient who underwent minimally invasive esophagectomy with retrosternal reconstruction using gastric conduit and cervical anastomosis. After four years, the patient experienced symptoms, including dyspnea and chest pain. CT scan revealed transverse colon herniation into the retrosternal tunnel. CLINICAL DISCUSSION: Our diagnosis was retrosternal herniation of the transverse colon. Although there was no sign of obstruction, the abundant colon in the retrosternal space caused mass effect symptoms. For that reason, we performed laparoscopic surgery to release the herniated organ and close the hernia hole. Postoperatively, the patient had a satisfactory recovery, and a follow-up CT scan confirmed the absence of any remaining herniated organs. CONCLUSION: While hiatal hernia is a well-known complication in minimally invasive esophagectomy, retrosternal hernia is a lesser-known entity. Surgical intervention is necessary to alleviate symptoms caused by herniation or address complications such as strangulation. The occurrence of retrosternal hernia warrants further attention and research in the future.
RESUMO
INTRODUCTION: Intrahepatic and extrahepatic lithiasis, a condition characterized by the presence of stones in the liver and bile ducts, is a common disease in Asia, particularly in East and Southeast Asia. We report a case with laparoscopic exploration of the common bile duct using a flexible cholangioscope and modified trans-common bile duct tunnel for hepatolithiasis combined with the dilated common bile duct. PRESENTATION OF CASE: A 35-year-old male patient has had chronic epigastric and right upper quadrant pain. The common bile duct was 11 mm dilated, and hepatolithiasis was also present, according to an upper abdomen MRI. The largest stone measured between 14 and 21 mm. A modified trans-common bile duct tunnel from the abdominal wall into the common bile duct was used in a laparoscopic procedure to examine the common bile duct. Complications during the procedure or following it were not present. The procedure took 120 min, and the blood loss was about 50 ml. The patient was discharged on the sixth postoperative day, and a follow-up visit one month later revealed that single-session stone clearance had been accomplished. DISCUSSION: Laparoscopic exploration of the common bile duct using a cholangioscope and modified trans-choledochal tube is applicable in selected patients and can be effectively and safely used to treat hepatolithiasis combined with the dilated common bile duct. CONCLUSION: In this case, we present an innovative approach for hepatolithiasis when combined with dilated common bile duct.
RESUMO
INTRODUCTION AND IMPORTANCE: Intrathoracic herniation of gastric conduit (IHGC) is a specific complication following esophagectomy with retrosternal gastric pull-up but is not well recognized. Diagnosis and management are challenging due to the lack of literature reviews. CASE PRESENTATION: We report a 50-year-old man where a reconstructed gastric conduit hernia into the mediastinal pleural cavity after esophagectomy. The patient underwent minimally invasive esophagectomy with cervical anastomosis for middle esophageal carcinoma followed by retrosternal reconstruction; during the tunneling phase, the mediastinal pleura was injured. Subsequently, the patient developed progressive dysphagia postoperatively, and chest CT scans revealed that the dilating gastric tube had moved into the mediastinal pleural cavity. CLINICAL DISCUSSION: After ruling out the pyloric stenosis by endoscopy, our diagnosis was severe gastric outlet obstruction due to gastric conduit herniation. We performed laparoscopic surgery to mobilize and straighten the redundant gastric conduit. No recurrence occurred throughout the follow-up for one year. CONCLUSION: IHGC can cause gastric conduit obstruction, which requires reoperation to repair. The laparoscopic approach is an appropriate strategy with the advantages of being less invasive and effective in mobilizing and straightening the gastric conduit. To prevent mediastinal pleural injury - which affects the continuation of the reconstructions, the surgeon should use blunt dissection with direct observation during the route creation.
