- Foramen of Winslow hernia: case report of a minimally invasive approachPublication . Brandão, P.; Mesquita, I.; Sampaio, M.; Martins, P.; Daniel, J.; Davide, J.Foramen of Winslow hernias account for 8% of all internal hernias. Their non-specific presentation and often late diagnosis are associated with an estimated mortality of 50%. The use of complementary diagnostic methods facilitates the diagnosis and planning of the therapeutic strategy. Urgent surgery is the appropriate treatment due to the risk of intestinal ischemia, being laparotomy the main form of approach described. Few cases of laparoscopy are referred to in the literature.
- Pancreas-Kidney Transplantation: Analysis of 150 patients from one Centre in PortugalPublication . Martins, La Salete; Fonseca, Isabel; Aguiar, P.; Rocha, A.; Costa, R.; Santos, C.; Malheiro, J.; Pedroso, S.; Almeida, M.; Dias, L.; Castro-Henriques, A.; Cabrita, A.; Davide, J.Introduction: Simultaneous pancreas-kidney transplantation (SPKT) outcomes are conditioned in the short-term mostly by post-operative complications. In the long-term, cardiovascular (CV) disease and immunological loss are the main limitations to transplant survival. Aims: To analyse retrospectively the results from 150 SPKT performed at our centre. Patients and Methods: The 81 females and 69 males had a mean age of 35±6 years; they were diabetic for 24±6 years and had been on dialysis for 30±21months (except 5 preemptive). Anti-lymphocyte globulin, tacrolimus, mycophenolate and steroids were used as immunosuppressive therapy. Deceased-donor mean age was 28±11 years. In 28.7% the transplant was performed with 6 HLA-mismatches. Results: Acute rejection’s incidence was 16%. Ten SPKT patients died; infection was the leading cause of death (five cases), followed by Cardiovascular/cerebrovascular disease (three cases). In 21 patients the pancreas failed, mainly due to thrombosis or bleeding (11 cases), and infection (five cases); in two it was due to late acute rejection. In four patients only the kidney failed, due to chronic rejection. Five patients lost both grafts, from late acute rejection in four and thrombosis in one. We analyzed the 110 SPKT patients (73.3%) with both grafts functioning. Their mean serum creatinine was 1.2±0.4mg/dl; creatinineclearance was 76±24 ml/min; fasting glycaemia was 81±10mg/dl; and HbA1c was 5.3±0.4%. Hypertension has been treated in 47.2% of patients, in the majority (28.2%) with only one drug. Hyperlipidaemia was observed in 19.1% and excessive weight (>25kg/m2) in 17.3%. Conclusions: From our cohort of SPKT, 93.3% of patients are alive, 73.3% have both grafts functioning. Rejection was the main cause of late pancreas loss. Early mortality was due to infection (3.3%). CV/cerebrovascular disease was the main cause of late mortality (2%). The prevalence of hyperlipidaemia and overweight was inferior to 20%. Hypertension was the most frequently found CV risk factor.
- Perforated duodenal diverticulum: Surgical treatment and literature reviewPublication . Costa Simões, V.; Santos, B.; Magalhães, S.; Faria, G.; Sousa Silva, D.; Davide, J.Duodenum is the second most frequent location for a diverticulum in the digestive tract. Complications are rare and perforation was only reported in less than 200 cases. PRESENTATION OF CASE: A 79-year-old female was admitted to Emergency Department with abdominal pain and vomiting for the last 24h. A CT scan was performed and moderated extra-luminal air was identified. During surgery a fourth portion perforated duodenal diverticulum was diagnosed and duodenal resection was performed. DISCUSSION: First reported in 1710, the incidence of duodenal diverticula can be as high as 22%. Nevertheless complications are extremely rare and include haemorrhage, inflammation, compression of surrounding organs, neoplastic progression, cholestasis and perforation. As perforations are often retroperitoneal, symptoms are nonspecific and rarely include peritoneal irritation, making clinical diagnose a challenge. CT scan will usually present extra-luminal retroperitoneal air and mesenteric fat stranding, providing clues for the diagnosis. Although non-operative treatment has been reported in selected patients, standard treatment is surgery and alternatives are diverse including diverticulectomy or duodenopancreatectomy. CONCLUSION: Perforated diverticula of the fourth portion of the duodenum are extremely rare and current evidence still supports surgery as the primary treatment modality.
- Type 2 Autoimmune Pancreatitis: A Challenge in the Differential Diagnosis of a Pancreatic MassPublication . Martins, C.; Lago, P.; Sousa, P.; Araújo, T.; Davide, J.; Castro-Poças, F.; Pedroto, I.Autoimmune pancreatitis is a rare entity of unknown etiology that can mimic pancreatic cancer and whose diagnosis involves clinical, serological, imagiological, and histological findings. There are two types of autoimmune pancreatitis: type 1, in which the pancreas is involved as one part of a systemic immunoglobulin G4-related disease, and type 2, generally without immunoglobulin G4-positive cells and without systemic involvement.
