We report the case of a 56-year-old woman with pancreatic adenocarcinoma (PA) discovered during an episode of febrile jaundice. A computed tomography (CT) scan showed a mass in the head of the pancreas with circumferential infiltration of the superior mesenteric vein (SMV) and dilatation of the biliary and pancreatic ducts without metastases. The patient benefited from neoadjuvant chemotherapy (FOLFIRINOX) followed by radio-chemotherapy (45 Gy) and chemotherapy (LV5FU2). The revaluation CT revealed SMV thrombosis without portal vein (PV) thrombosis. There was no contact of the tumor with the PV. Pancreatoduodenectomy with combined resection of the SMV was performed with no reconstruction of this venous axis after confirmation of adequate PV, splenic, and left gastric venous flow and the absence of bowel ischemia. The pathological diagnosis was pT4N1R0 PA. There were no bowel angina issues during the follow-up period. At 15 mo after surgery, the patient died of metastatic recurrence. 相似文献

Laparoscopic pancreatic surgery is one of the most difficult procedures, and the adoption of laparoscopic pancreaticoduodenectomy has been limited. The application of laparoscopic surgery has extended to advance cancer, but there have been no reports of laparoscopic pancreaticoduodenectomy after laparoscopic liver resection and distal pancreatectomy. In the present case, a 67‐year‐old woman was diagnosed with remnant pancreatic recurrence of metastatic greater omentum leiomyosarcoma. She had previously undergone laparoscopic distal pancreatectomy and left lateral liver sectionectomy in 2016. We performed laparoscopic subtotal stomach‐preserving pancreaticoduodenectomy in June 2017. The operation time was 274 minutes, and the estimated blood loss was 50 mL. There were no postoperative complications. In summary, laparoscopic pancreaticoduodenectomy is a safe and feasible procedure for a patient who had previously undergone pancreas and liver surgery. 相似文献

For multiple low‐grade malignant tumors located in the pancreatic head and tail, middle‐segment–preserving pancreatectomy (MSPP) is sometimes indicated. However, MSPP has rarely been performed laparoscopically. Here we report the first case of laparoscopic MSPP for multiple pancreatic neuroendocrine tumors diagnosed preoperatively under an endoscopic ultrasound‐guided fine‐needle aspiration biopsy. A 70‐year‐old man had multiple small tumors located in the pancreatic head, body and tail. Endoscopic ultrasound‐guided fine‐needle aspiration biopsy with immunohistochemical staining made a definitive diagnosis of a pancreatic neuroendocrine tumor (G1). To preserve the 5‐cm pancreas body, we successfully performed laparoscopic MSPP: subtotal stomach‐preserving pancreaticoduodenectomy followed by distal pancreatosplenectomy. Pathological examination revealed negative surgical margin after resection. Postoperative course was uneventful, and at 14 months after the operation, the patient remains tumor‐free. The patient has discontinued insulin supplement therapy but does use an oral hypoglycemic agent. Laparoscopy‐assisted MSPP, with reconstruction through a 6‐cm transverse incision, can be safely performed for selected cases of borderline and malignant lesions. 相似文献

Gastrointestinal stromal tumors of the duodenum are rare. For benign tumors, premalignant lesions, or malignant potential tumors located in the second portion of the duodenum close to the papilla of Vater, pancreaticoduodenectomy is sometimes performed. A case of laparoscopic segmental duodenectomy for a gastrointestinal stromal tumor at the second portion of the duodenum is reported. The surgical procedure was performed as follows: first, the second portion of the duodenum was separated from the pancreatic head; second, the duodenum was cut off with the linear stapler after having confirmed preservation of the papilla by intraoperative endoscopy; and third, reconstruction was carried out by a side‐to‐side duodenojejunostomy. Laparoscopic segmental duodenectomy for duodenal gastrointestinal stromal tumors is thought to be advantageous compared with pancreaticoduodenectomy in terms of low burden and organ function preservation. The present procedure is feasible for benign or low‐malignant tumors that do not infiltrate outside of the duodenal walls. 相似文献

OBJECTIVE: To compare the ability of state-of-the-art ultrasonography with that of helical computed tomography and computed tomographic angiography in detecting unresectable periampullary cancer. In most patients periampullary cancer is unresectable because of either distant metastasis or local vascular involvement. The advent of gray scale and color Doppler ultrasonography has improved the ability of ultrasonography to detect vascular involvement. METHODS: Twenty-three consecutive patients with periampullary cancer were enrolled for prospective staging of their disease by comparing helical computed tomography and computed tomographic angiography with gray scale and color Doppler ultrasonography of the abdomen. Portal vein, superior mesenteric vein, splenic vein, and superior mesenteric artery involvement was graded 0 to 4, grade 0 being no vascular involvement and grade 4 being total occlusion of the vessel. Agreement between ultrasonography and computed tomographic angiography for determining vascular involvement was measured by chi2 analysis. RESULTS: Two patients (9%) were excluded because excessive overlying bowel gas hampered the ability of ultrasonography to visualize the pancreas. For the remaining 21 patients, there was significant agreement between ultrasonography and computed tomographic angiography for detecting vascular involvement in all vessels (P < .001; portal vein, kappa = 0.67; superior mesenteric vein, kappa = 0.67; splenic vein, kappa = 0.85; and superior mesenteric artery, kappa = 0.59). Ultrasonography was in agreement with computed tomographic angiography in all cases of unresectability. Both modalities were equally poor in preoperatively showing lymphadenopathy and metastases. CONCLUSIONS: Provided that there is adequate visualization on ultrasonography of the head of the pancreas in the periampullary region, then state-of-the-art gray scale and color Doppler ultrasonography are as accurate as helical computed tomography and computed tomographic angiography for detecting the unresectability of periampullary cancer. If performed as the initial investigation and the region of the pancreatic head is clearly shown, and if vascular encasement or occlusion or distant metastasis is identified, further investigations are unnecessary. 相似文献

A 39‐year‐old female patient underwent anterior resection with locoregional lymph node dissection for rectosigmoid cancer at another hospital. The procedure involved transection of the superior rectal artery just below the origin of the left colic artery. Postoperative diagnosis was stage III B. The patient received adjuvant chemotherapy with oxaliplatin plus capecitabine for 6 months. Sixteen months after the operation, PET‐CT scans revealed regional lymph node metastases around the root of the inferior mesenteric artery. The patient was referred to our hospital with a recurrence of rectosigmoid cancer. We performed laparoscopic lymph node dissection with real‐time indocyanine green fluorescent images superimposed on color images to prevent intraoperative vascular insufficiency. We were able to successfully observe the sufficient blood flow in the descending colon. Postoperative pathological findings showed lymph node recurrence after initial surgery. She was discharged 7 days after the operation. In the 8 months since the second operation, the patient has not had any indication of further recurrence. 相似文献

Laparoscopic pancreaticoduodenectomy (PD) has been reported to be technically feasible and safe. Successful pancreatico-enteric anastomosis in particular is important for safe PD. Intraoperative perfusion of the remnant pancreas can be evaluated with ICG technology and be applied in pancreatic reconstruction in PD. A 68-year old female patient with distal common bile duct cancer underwent laparoscopic pylorus-preserving pancreaticoduodenectomy. After pancreaticojejunostomy (PJ), we checked perfusion of the anastomosis line using an ICG imaging system and noticed a perfusion defect at the anterior wall. The patient developed a grade A postoperative pancreatic fistula, but was discharged without major sequelae. Even though pancreatic perfusion after laparoscopic PJ appeared adequate based on white light, hypo-perfusion was noted under infrared light. Our experience suggests that ICG technology may be more sensitive than white light for detecting pancreatic perfusion in pancreatic anastomoses. However, the clinical implications of this require further investigation. 相似文献

A prospective study was designed to determine the utility of computed tomography (CT) during arterial portography (CTAP) in the detection of superior mesenteric vessels and portal vein involvement in patients with pancreatic adenocarcinoma. Eighteen patients with adenocarcinoma of the head of the pancreas and eight patients with benign pancreatic disease were investigated with CTAP, dynamic contrast-enhanced CT, and angiography. Appropriate review was made to determine presence or absence of superior mesenteric vessels and portal vein involvement. Final diagnosis was obtained in all cases by surgical explorations. The overall accuracy rate for detecting or excluding superior mesenteric vessels and portal vein involvement was 96% (25 of 26 patients) with CTAP, 88% (23 of 26 patients) with dynamic contrast-enhanced CT, and 85% (22 of 26 patients) with angiography. No statistically significant difference in accuracy was found among the three techniques. Our results suggest that the use of CTAP is not indicated in the preoperative detection of superior mesenteric vessels and portal vein involvement in patients with pancreatic adenocarcinoma. 相似文献

Here we report a combined laparoscopic abdominoperineal resection and robotic‐assisted prostatectomy. A 74‐year‐old man was diagnosed with T4b low rectal and prostate cancer. The operation was performed after neoadjuvant chemotherapy for the rectal cancer. The procedure used eight ports in total, five for laparoscopic abdominoperineal resection and six for robotic‐assisted prostatectomy. First, laparoscopic total mesorectal excision including division of the inferior mesenteric artery was performed, and then, robotic dissection of the prostate was performed. The en bloc specimen was removed through the perineal wound. Then, robotic urethrovesical anastomosis was performed. An extraperitoneal end colostomy was created to finish the operation. The operating time was 545 min, and blood loss was 170 mL. The postoperative course was uneventful, and the patient discharged on postoperative day 17. The combined laparoscopic abdominoperineal resection and robotic‐assisted prostatectomy were performed safely without any additional technical difficulty, as both procedures shared port settings and patient positions. 相似文献

A 30‐year‐old Japanese woman presented at our hospital with a pancreatic tumor. Contrast‐enhanced CT revealed a tumor with a 12‐cm diameter in the pancreatic body and tail. In the preoperative setting, endoscopic ultrasound‐guided fine‐needle aspiration permitted a histopathological diagnosis of solid pseudopapillary neoplasm. Twhe patient underwent laparoscopic distal pancreatectomy with splenectomy. Our procedure involved three steps. Firstly, the splenic artery was occluded to block inflow of blood to the tumor. Then, we transected the neck of the pancreas using radical antegrade modular pancreatosplenectomy. Finally, hand‐assisted laparoscopic surgery allowed us to secure the operating field and easily handle the large tumor. This enabled us to accomplish laparoscopic distal pancreatectomy, and en‐bloc resection was completed. The patient was discharged without major complications. Laparoscopic distal pancreatectomy for huge solid pancreatic tumors can be completed safely. 相似文献
