RESUMO

INTRODUCTION: Geriatricians have been increasingly involved in the pre-operative process in frail elderly patients with a hip fracture which can benefit re-hospitalization, post-operative functional performance, and mortality. The objective of this study was to compare the number of older patients with hip fractures who opted for non-surgical management after the addition of pre-operative comprehensive geriatric assessment (CGA) with shared decision making by a geriatrician to usual care. Secondary objectives were: reasons for non-surgical management, duration of life, and location of death. MATERIALS AND METHODS: A single-center, with a level 2 trauma center, retrospective study comparing care before and after introducing pre-operative CGA with shared decision making in September 2014. Patients ≥ 70 years with a hip fracture, admitted from January 2014 to September 2015, were included. The percentages of patients elected for non-surgical management and palliative care without or with CGA were compared. Differences in secondary objectives (age, sex, medical history, medication use, functional, and social status) were compared descriptively and qualitatively. RESULTS: With pre-operative CGA significantly more patients (or representatives) elected the non-surgical management option after hip fracture (respectively, 9.1% vs 2.7%, p = 0.008). Patient characteristics were comparable. Reported reasons not to undergo surgery include aversion to be more dependent on others, and severe dementia. CONCLUSION: The geriatrician can have an important role in decisions for non-surgical management by shared decision making in the pre-operative period in patients ≥ 70 years with a hip fracture in the emergency room.

RESUMO

Polycystic liver disease (PCLD) is an inherited disorder caused by mutations in either PRKCSH (hepatocystin) or SEC63 (Sec63p). However, expression patterns of the implicated proteins in diseased and normal liver are unknown. We analyzed subcellular and cellular localization of hepatocystin and Sec63p using cell fractionation, immunofluorescence, and immunohistochemical methods. Expression patterns were assessed in fetal liver, PCLD liver, and normal adult liver. We found hepatocystin and Sec63p expression predominantly in the endoplasmic reticulum. In fetal tissue, there was intense expression of hepatocystin in ductal plate, bile ducts, and hepatocytes. However, Sec63p staining was prominent in early hepatocytes only and weak in bile ducts throughout development. In PCLD tissue, hepatocystin was expressed in hepatocytes, bile ducts, and in cyst epithelium of patients negative for PRKCSH mutation. In contrast, the majority of cysts from PRKCSH mutation carriers did not express hepatocystin. Sec63p expression was observed in all cyst epithelia regardless of mutational state. We conclude that hepatocystin is probably required for development of bile ducts and does not interact with Sec63p. The results support the hypothesis that cyst formation in PCLD results from a cellular recessive mechanism involving loss of hepatocystin. Cystogenesis in SEC63-associated PCLD occurs via a different mechanism.

RESUMO

INTRODUCTION: Patients with polycystic liver disease (PCLD) may develop symptoms due to increased liver volume. Laparoscopic fenestration is one of the options to reduce liver volume and to relieve symptoms. This study was performed to evaluate the safety and efficacy of laparoscopic liver cyst fenestration. PATIENTS AND METHODS: Twelve patients (all female, median age 45 years, range 35-58) with symptomatic PCLD were included between August 2005 and April 2007. Surgical data were recorded, liver volumes were measured on pre- and postoperative computed tomography (CT) scans, and patients completed a validated symptom-based questionnaire pre- and postoperatively. RESULTS: Median preoperative liver volume was 4,854 ml (range 1,606-8,201) and decreased to 4,153 ml postoperatively (range 1,556-8,232) resulting in median liver volume reduction of 12.5% (range +9.5 to -24.7%). Median procedural time was 123.5 min (range 50-318), and median hospitalization period was 3.5 days (range 1-8). Postoperative complications occurred in three patients including biliary leakage, obstruction of inferior vena cava and sepsis, all recovering with conservative management. Patients reported decreased symptoms of postprandial fullness and abdominal distension. CONCLUSION: Laparoscopic fenestration in PCLD patients results in volume reduction of 12.5% and decrease of symptoms.

RESUMO

BACKGROUND: Repair of a large, severely contaminated abdominal wall defect is a challenging problem. Most patients are currently treated with a multistaged procedure, which is time consuming, carries a high complication rate, and is often not finalized. STUDY DESIGN: In this study, our experience with a one-stage repair of contaminated abdominal wall defects using the Components Separation Method was evaluated with respect to morbidity and recurrence. Medical records of patients with contaminated abdominal wall defects, treated with the Components Separation Method from 1996 to 2000, were studied. Patients were invited to visit the outpatient clinic for a physical examination. RESULTS: Twenty-six patients with a median age of 49 years and a mean defect size of 267 cm2 were treated. Intraoperative contamination, graded according to the National Research Council (NRC), showed 22 National Research Council III patients and 4 National Research Council IV patients. Postoperatively, five superficial wound infections, three cases of pneumonia, three instances of recurrent enterocutaneous fistulation, and two cases of sepsis were observed. One of the patients with sepsis died after anastomotic disruption led to peritonitis and multiple organ failure. Two asymptomatic recurrences were diagnosed (8%) after a median followup of 27 months. CONCLUSIONS: Large contaminated abdominal wall hernias can be closed by the Components Separation Method, with a low recurrence rate but considerable morbidity.

RESUMO

Incisional hernia repair without mesh mainly consists of tissue transfer to bridge or close the defect. Bridging includes rotational or free musculocutaneous flaps, rendering acceptable short-term results but a rather disappointing long-term outcome. Abdominal wall closure where there has been significant loss of domain, with intraperitoneal organs residing permanently outside the abdominal cavity, can only be achieved using the patients' own tissue if preoperative expansion of the abdominal cavity is performed using artificial expanders or pneumoperitoneum. From a scientific point of view, however, evidence supporting any treatment option is weak because prospective randomized controlled trials are virtually impossible to conduct owing to the inhomogeneity of the patient population being considered. Treatment of this condition by the above-mentioned means should therefore be proposed on an individual basis utilizing one or more of the many possible techniques described.
