Pancreaticoduodenectomy after neoadjuvant chemotherapy for gastric cancer invading the pancreatic head:A case report

BACKGROUND Pancreaticoduodenectomy(PD)for advanced gastric cancer is rarely performed because of the high morbidity and mortality rates and low survival rate.However,neoadjuvant chemotherapy for advanced gastric cancer has improved,and chemotherapy combined with trastuzumab may have a preoperative tumorreducing effect,especially for human epidermal growth factor receptor 2(HER2)-positive cases.CASE SUMMARY We report a case of successful radical resection with PD after neoadjuvant S-1 plus oxaliplatin(SOX)and trastuzumab in a patient(66-year-old male)with advanced gastric cancer invading the pancreatic head.Initial esophagogastroduodenoscopy detected a type 3 advanced lesion located on the lower part of the stomach obstructing the pyloric ring.Computed tomography detected lymph node metastasis and tumor invasion to the pancreatic head without distant metastasis.Pathological findings revealed adenocarcinoma and HER2 positivity(immunohistochemical score of 3+).We performed staging laparoscopy and confirmed no liver metastasis,no dissemination,negative lavage cytological findings,and immobility of the distal side of the stomach due to invasion to the pancreas.Laparoscopic gastrojejunostomy was performed at that time.One course of SOX and three courses of SOX plus trastuzumab were administered.Preoperative computed tomography showed partial response;therefore,PD was performed after neoadjuvant chemotherapy,and pathological radical resection was achieved.CONCLUSION We suggest that radical resection with PD after neoadjuvant chemotherapy plus trastuzumab is an option for locally advanced HER2-positive gastric cancer invading the pancreatic head in the absence of non-curative factors.

Indirect inguinal hernia containing portosystemic shunt vessel: A case report

BACKGROUND Inguinal hernia repair is one of the most common general surgical operations worldwide.We present a case of indirect inguinal hernia containing an expanded portosystemic shunt vessel.CASE SUMMARY We report a 72-year-old man who had a 4 cm×4 cm swelling in the right inguinal region,which disappeared with light manual pressure.Abdominal-pelvic computed tomography(CT)revealed a right inguinal hernia containing an expanded portosystemic shunt vessel,which had been noted for 7 years due to liver cirrhosis.We performed Lichtenstein’s herniorrhaphy and identified the hernia sac as being indirect and the shunt vessel existing in the extraperitoneal cavity through the internal inguinal ring.Then,we found two short branches between the expanded shunt vessel and testicular vein in the middle part of the inguinal canal and cut these branches to allow the shunt vessel to return to the extraperitoneal cavity of the abdomen.The hernia sac was returned as well.We encountered no intraoperative complications.After discharge,groin seroma requiring puncture at the outpatient clinic was observed.CONCLUSION If an inguinal hernia patient has portal hypertension,ultrasound should be used to determine the contents of the hernia.When atypical vessels are visualized,they may be shunt vessels and additional CT is recommended to ensure the selection of an adequate approach for safe hernia repair.

Distal gastric tube resection with vascular preservation for gastric tube cancer:A case report and review of literature

BACKGROUND Survival rates in patients with esophageal cancer undergoing esophagectomy have improved,but the prevalence of gastric tube cancer(GTC)has also increased.Total resection of the gastric tube with lymph node dissection is considered a radical treatment,but GTC surgery is more invasive and involves a higher risk of severe complications or death,particularly in elderly patients.CASE SUMMARY We report an elderly patient with early GTC that had invaded the duodenum who was successfully treated with resection of the distal gastric tube and Roux-en-Y(R-Y)reconstruction.The tumor was a type 0-IIc lesion with ulcer scars surrounding the pyloric ring.Endoscopic submucosal resection was not indicated because the primary lesion was submucosally invasive,was undifferentiated type,surrounded the pyloric ring,and had invaded the duodenum.Resection of distal gastric tube with R-Y reconstruction was safely performed,with preservation of the right gastroepiploic artery(RGEA)and right gastric artery(RGA).CONCLUSION Distal resection of the gastric tube with preservation of the RGEA and RGA is a good treatment option for elderly patients with cT1bN0 GTC in the lower part of the gastric tube.

Unresectable esophageal cancer treated with multiple chemotherapies in combination with chemoradiotherapy:A case report

BACKGROUND Definitive chemoradiotherapy(dCRT)using cisplatin plus 5fluorouracil(CF)with radiation is considered the standard treatment for unresectable locally advanced T4 esophageal squamous cell carcinoma(ESCC).Recently,induction chemotherapy has received attention as an effective treatment strategy.CASE SUMMARY We report a successful case of a 59-year-old female with unresectable locally advanced T4 ESCC treated by two additional courses of chemotherapy with CF after induction chemotherapy with docetaxel,cisplatin and fluorouracil(DCF)followed by dCRT.Initial esophagogastroduodenoscopy(EGD)detected a type 2 advanced lesion located on the middle part of the esophagus,with stenosis.Computed tomography detected the primary tumor with suspected invasion of the left bronchus and 90°of direct contact with the aorta,and upper mediastinal lymph node metastasis.Pathological findings from biopsy revealed squamous cell carcinoma.We initially performed induction chemotherapy using three courses of DCF,but the lesion was still evaluated unresectable after DCF chemotherapy.Therefore,we subsequently performed dCRT treatment(CF and radiation).After dCRT,prominent reduction of the primary tumor was recognized but a residual tumor with ulceration was detected by EGD.Since the patient had some surgical risk,we performed two additional courses of CF and achieved a clinically complete response.After 14 mo from last administration of CF chemotherapy,recurrence has not been detected by computed tomography and EGD,and biopsy from the scar formation has revealed no cancer cells.CONCLUSION We report successful case with tumor remnants even after DCF and subsequent dCRT,for whom a complete response was finally achieved with two additional courses of CF chemotherapy.Additional CF chemotherapy could be one radical treatment option for residual ESCC after treatment with induction DCF followed by dCRT to avoid salvage surgery,especially for high-risk patients.
