There has been an increasing awareness of post gastric bypass hypoglycemia (PGBH). Histopathologic findings fromsuch patients who underwent partial/total pancreatomy, however, can vary widely from minimal changes to classic nesidioblastosis, making the pathologic diagnosis challenging. PGBH typically presents as postprandial hypoglycemia, as opposed to insulinoma, which presents as fasting hypoglycemia. Herein, we describe an unusual case of a patient with PGBH who initially presented with postprandial hypoglycemia three years after surgery, but later developed fasting hyperinsulinemic hypoglycemia as the disease progressed. Our hypothesis for this phenomenon is that this disease is progressive, and later in its course, the insulin release becomes dissociated from food stimulation and is increased at baseline. Future studies are needed to investigate the prevalence as well as etiology of this progression from postprandial to fasting hypoglycemia. Learning points: •• There has been an increasing awareness of post gastric bypass hypoglycemia (PGBH). •• Histopathologically, PGBH can vary from minimal changes to nesidioblastosis. •• Although uncommon, patients with PGBH after Roux-en-Y gastric bypass may present with both postprandial and fasting hyperinsulinemic hypoglycemia as disease progresses. •• Our hypothesis for this phenomenon is that the insulin release becomes dissociated from food stimulation and is increased at baseline with disease progression.

We report 2 cases of prolonged survival achieved with surgical resection and multidisciplinary therapy for acinar cell carcinoma of the pancreas with liver metastases.Case 1: The patient was a 55-year-old woman.She presented with upper right abdominal pain and anemia.We diagnosed a tumor originating from the pancreas and multiple liver metastases.To avoid death caused by bleeding from the tumor, we performed pancreaticoduodenectomy and right-hemi hepatectomy, and a rapid diagnosis of acinar cell carcinoma of the pancreas was confirmed intraoperatively.After the hospital discharge, we administered hepatic intra-arterial chemotherapy and performed microwave ablation for the remnant liver metastases.Additionally, systemic chemotherapy with gemcitabine was administered; however, multiple metastases of the lung and liver became uncontrollable and she died 2 and half years postoperatively.Case 2: The patient was a 42-year-old woman.Through a medical checkup, gastric varix and elevated tumor markers were detected.The examination revealed a tumor at the tail of the pancreas and liver metastasis.We performed distal pancreatomy and partial liver resection.The pathological diagnosis was acinar cell carcinoma and liver metastasis.We administered adjuvant chemotherapy by using gemcitabine and achieved 5 years of relapse-free survival.The prognosis of ACC is better than that for PDAC.However, prognosis of unresectable cases is still unfavorable.Therapeutic strategies including aggressive surgical resection for metastatic ACC are worthy of consideration.

We report a case where resection was performed for pancreatic metastasis from renal cell carcinoma 21 years after nephrectomy. A 72-year-old man had undergone total gastrectomy with distal pancreatomy and splenectomy for gastric cancer, and right nephrectomy for primary renal cell carcinoma in 1993. Incidentally, a CT scan performed in 2014 revealed a tumor in the head of the pancreas. Enhanced MRI suggested that the tumor contained some fat tissue. The tumor in the pancreatic body had sharp margins; therefore, we performed subtotal pancreatectomy. The tumor was considered pancreatic metastasis from renal cell carcinoma. Pathological findings indicated clear-cell type carcinoma(G1-G2), which is very similar to renal cell carcinoma. We diagnosed pancreatic metastasis from renal cell carcinoma. The patient has remained well, with no recurrence 20 months after the pancreatectomy.

Segmental arterial mediolysis (SAM) is characterized by intra-abdominal, retroperitoneal bleeding or bowel ischemia, and the etiology is unknown. A 44-year-old man complaining of abdominal pain was admitted to our hospital. He had been admitted for a left renal infarction three days earlier and had a past medical history of cerebral aneurysm with spontaneous remission. The ruptured site of the splenic arterial aneurysm was clear via a celiac angiography, and we treated it using trans-arterial embolization. Unfortunately, the aneurysm reruptured after two weeks, and we successfully treated it with distal pancreatomy and splenectomy. We recommended a close follow-up and prompt radiological or surgical intervention because SAM can enlarge rapidly and rupture.

Opioids are an essential part of cancer pain management but particularly in this patient group physicians could misinterpret opioid-induced potentially life-threatening side effects within the central nervous system (CNS) or hyperalgesia as a consequence of tumor progression. In this case increasing the opioid dose or switching to rapidly acting opioids may trigger a vicious circle. We describe a case report of a male patient who was treated with high doses of transdermal and endonasal fentanyl 2 years after pancreatomy due to cancer. The patient was referred to the palliative care unit presenting with delirious behavior and 30-40 severe abdominal pain attacks/day. After withdrawal of the opioid medication all CNS symptoms disappeared. Further diagnostics revealed multiple incisional hernia as the reason of the pain syndrome. The patient recovered after herniotomy and has now been pain free without any pain medication for more than 16 months. This case report underlines again the necessity of pain diagnostics also in assumed palliative patients with the risks of high dose opioid treatment.
- Robotic hepatobiliary and pancreatic surgery: lessons learned and predictors for conversion. [Clinical Trial]
- IJInt J Med Robot 2013; 9(2):152-9
- CONCLUSIONS: Robotic-assisted hepatobiliary and pancreatic procedures are often extremely complex, with a significant learning curve. Recognizing factors that prohibit successful completion of a robotic-assisted surgical procedure is key for patient safety. Careful patient selection in the appropriate settings facilitates the maximal benefit of robotic-assisted complex HPB surgery.

The frequency of upper gastrointestinal hemorrhage as a postoperative complication of cephalic duodenopancreatectomy remained constant for decades despite the overall decrease in the incidence of mortality occuring after cephalic duodeno-pancreatomy. It is the second most common complication after anastomotic fistulas, but more frequently fatal, especially when the pancreas is anastomosed with the stomach. The case presented here is of a patient of 55 years age, diagnosed in our clinic with vaterian ampuloma for which was performed cephalic duodenopancreatectomy and gastrointestinal and hepatobiliary continuity was restored by performing terminolateral pancreato-gastric anastomosis, termino-lateral hepato-jejunal anatomosis and termino-lateral gastro-jejunal anastomosis on a jejunal loop ascended transmezocolic. Postoperative evolution of the patient was marked by appearance of two episodes of upper gastrointestinal hemorrhage, the first being solved by relaparotomy and the second benefiting from the contribution of an endoscopic intervention. From this case, we analyze risk factors for upper gastrointestinal hemorrhage appearing after cephalic duodeno-pancreatectomy and its therapeutic modalities, starting from the fact that currently there is no consensus among experts on this matter.

The prognosis of pancreatic cancer is most dismal in all gastrointestinal cancers, because the patients with pancreatic cancer are vulnerable for recurrence such as local relapse and liver metastasis even after a complete surgical resection. We herein report a case of pancreatic cancer, which underwent resection of local relapse and multiresections of liver metastases, resulting in a relatively longer survival. A 71-year-old woman was referred to our hospital for a local recurrence in the tail of the pancreas in October 2006, 17 months after the first distal pancreatectomy. A second distal pancreatectomy was curatively performed on this patient. After the second surgery, sequent solitary liver metastases appeared, and we then performed partial hepatectomies repeatedly in August 2007, December 2007 and December 2008. The histopathological findings of each specimen from the resected liver showed tubular adenocarcinoma, same as the original pancreatic tumor obtained from the first surgery. Although chemotherapy was not permitted due to gemcitabine-induced interstitial pneumonitis, the patient is still alive over 4 years after the first operation under palliative care. This study discusses a controversial issue about the resection of the liver metastases from pancreatic cancer, along with the necessity for careful selection of the patients before attempting the operation.

A 49-year-old, previously healthy woman sought treatment for abdominal pain. Colonoscopy revealed ascending colon cancer. Computed tomography and angiography showed splenic metastasis and thrombosis extending from the splenic vein to the portal vein. She underwent right hemicolectomy, splenectomy, and distal pancreatomy. Histological findings showed no malignant cell in the splenic vein which was filled with organizing thrombus. We postulate the mechanism of splenic vein thrombosis in our case to be secondary to the extrinsic compression of the splenic vein by the splenic metastasis or by the inflammatory process produced by the splenic metastasis. In conclusion, we suggest that splenic metastasis should be added to the list of differential diagnosis which causes splenic vein thrombosis. In the absence of other sites of neoplastic disease, splenectomy seems to be the preferred therapy because it can be performed with low morbidity and harbors the potential for long-term survival.

This report describes the case of a patient who underwent total gastrectomy, splenectomy and pancreatomy corporo-postero as a consequence of gastric and pancreatic metastasis from carcinoma to clear cells, five years after having undergone radical nephrectomy. Upper digestive bleeding was the first symptom, and pancreatic lesion was detected in previous CT scans. There are many documented cases of pancreatic metastasis, but only eight gastric metastasis in the last 15 years, although we did not find reports about surgical treatment for concomitant gastric and pancreatic injury. Surgical treatment which in some reports include highly complex surgeries such as gastrectomies with combined resections of invaded organs and pancreatoduodenectomy, are good options for select cases, because good survival rates have been reported.
