Survival and Health Outcomes After Cytoreductive Surgery With Intraperitoneal Hyperthermic Chemotherapy for Disseminated Peritoneal Cancer of Appendiceal Origin

BACKGROUND: Cytoreductive surgery with intraperitoneal hyperthermic chemotherapy for peritoneal carcinomatosis of appendiceal origin can alleviate symptoms and prolong survival. This aggressive therapy may impair patient quality of life (QOL). The purpose of this study was to monitor health outcomes before and after treatment. METHODS: Patients underwent cytoreductive surgery and intraperitoneal hyperthermic chemotherapy for peritoneal cancer. Patients completed questionnaires consisting of demographic information and the Functional Assessment of Cancer Therapy, the SF-36 Medical Outcomes Study survey, the Center for Epidemiologic Studies-Depression Scale, and the ECOG Performance Status Rating before (T1) and after surgery at 3 (T2), 6 (T3), 12 (T4), and 24 (T5) months. Time trends were assessed with the mixed model (SAS PROC MIXED) to allow use of all the observed data as well as to account for missing data. RESULTS: Fifty-eight patients (50% female) with a mean age 52.4 years (SD 12.6; range, 28-80) were assessed before surgery. Overall survival at 1 year was 78.7%. Emotional well-being improved over the study period, while physical well-being and physical functioning declined at T2 and then improved to near baseline levels at T3 and T4. Percentage of patients with depressive symptoms was as follows: T1 = 24%, T2 = 30%, T3 = 24%, and T4 = 33%. QOL scores improved over time. CONCLUSIONS: Although complications can affect short-term recovery, survival in appendix cancer patients with peritoneal cancer is good and for some can be achieved without major decrements in QOL at 1 year. Depressive symptoms and some physical limitations remain in surviving patients.     

Endoscopic vacuum-assisted closure of anastomotic leakage following anterior resection of the rectum: a new method

BACKGROUND: Conservative treatment of anastomotic leakage after anterior resection of the rectum seems to be possible in patients who have no occurrence of generalized peritonitis. This report describes a new method of endoscopic management of large anastomotic leakage in these patients. METHOD: The main feature of this new method is the endoscopically assisted placement of an open-cell sponge connected to a vacuum device into the abscess cavity via an introducer device. The sponge system is changed every 48-72 h. RESULTS: Twenty-nine patients with an anastomotic leakage after anterior resection were treated with the endoscopic vacuum therapy. The total duration of endovac therapy was 34.4 +/- 19.4 days. The total number of endoscopic sessions per patient was 11.4 +/- 6.3. In 21 of the 29 patients, a protecting stoma was created at the primary operation. Four patients were treated successfully without the need of a secondary stoma. Definitive healing was achieved in 28 of the 29 patients. CONCLUSIONS: Endoscopic vacuum-assisted closure is a new efficacious modality for treating anastomotic leakage following anterior resection due to an effective control of the septic focus. Further studies will show if it is possible to reduce the high mortality rate of patients with anastomotic leakage through the avoidance of surgical reinterventions while at the same time preserving the sphincter function.     

Range of motion during the perioperative period in total knee arthroplasty

INTRODUCTION: This study focused on the change in the range of motion (ROM) during the perioperative period, i.e., the preoperative and intraoperative ROM, and that on discharge, and compared the difference between posterior cruciate ligament-retaining (PCLR) and -sacrificing (PCLS) prostheses. MATERIALS AND METHODS: In this prospectively randomized study, we compared the changes in the ROM in PCLR (n = 50) and PCLS (n = 50) total knee arthroplasties. RESULTS: The mean flexion in PCLR prostheses was 130.0 degrees preoperatively, 120.0 degrees intraoperatively, and 105.0 degrees at discharge, and 125.0 degrees , 120.0 degrees , and 100.0 degrees , respectively, in PCLS. The designs did not differ statistically in each period (P > 0.05). Both designs showed significant correlations between the preoperative and intraoperative ROM, and between the preoperative and discharge ROM. Only the PCLS showed a significant correlation between the intraoperative and discharge ROM, and a significant difference was observed in correlation of rank coefficient between the two prostheses (P < 0.001). CONCLUSIONS: The PCLS design has an advantage in rehabilitation planning because of the predictable changes in the ROM during the perioperative period, although the acquired average ROM at discharge did not differ statistically.     

Sagittal plane analysis of the open and closed methods in children with displaced supracondylar fractures of the humerus (a radiological study)

OBJECTIVES: The aim of this study was to compare the radiological outcome of open and close reduction and osteosynthesis methods in the treatment of type II and III supracondylar humerus fractures in childhood with respect to the immediate post-operative reduction quality in sagittal plane. METHOD: One hundred and forty four-pediatric patients with type IIb and III supracondylar humerus fractures treated at two centers between 1995 and 2005 were evaluated radiologically within a retrospective study. Seventy-six patients (54 boys, 22 girls, mean age 7.6, range 2-12) were treated by closed reduction and cross percutaneous pinning while 68 (49 boys, 19 girls, mean age 7.3, range 2-13) were treated by open reduction. The reduction quality of the open and closed groups was compared on immediate post-operative lateral radiographs by measuring of lateral humerocapitellar angle, anterior humeral line and anterior coronoid line criteria. The reduction quality was classified excellent, good, fair and poor according to the achievement of three, two, one or none of the criteria, respectively. Reductions classified as excellent and good were introduced as acceptable results. RESULTS: At least one criterion was achieved in all the patients of both the groups. The mean humerocapitellar angle was 30.1 degrees in closed reduction group while the mean of it was 29.8 degrees in open reduced group. Radiograph of 48 (63.1%) patients with closed reduction were found to display the anterior humeral line intersecting the middle one-third of capitellum while this criteria was 45 (66%) in open reduction group. The anterior coronoid line was disturbed in three patients in each of both the groups. The reduction quality was evaluated to be excellent in 32 patients, good in 31, fair in 13 at the closed reduction group while these evaluations were 31, 20 and 17 in open reduction group, respectively. Successful reduction was achieved in 74.9% of the patients in closed reduction group and 75% of the patients in open reduction group. CONCLUSION: It is concluded that there was no significant difference between closed and open reductions of pediatric displaced supracondylar fractures with regard to the radiological criteria of reduction quality in sagittal plane.     

Roux-en-Y gastric bypass procedure performed with the da Vinci robot system: is it worth it?

BACKGROUND: The Roux-en-Y gastric bypass procedure (RYGBP) is in many countries the gold standard for obtaining long-lasting weight reduction and improvement of obesity-related comorbidities. However, performing this operation by standard laparoscopic techniques requires important surgical skills because of the anastomoses involved. The da Vinci surgical robot system with its enhanced degrees of freedom in motion and three-dimensional vision is designed to overcome the difficulties encountered in traditional laparoscopic surgery with suturing and delicate tissue handling. METHODS: For this study, 45 patients (9 men) with a mean body mass index (BMI) of 44.2 (range, 35.1-55.4) underwent RYGBP with the aid of the da Vinci robot system. They were compared with 45 consecutive patients with a mean BMI of 43.9 (range, 35.1-56.2) who underwent a laparoscopic RYGBP by the same surgeon during the same period. RESULTS: Overall, the total operating time was shorter for the laparoscopic cases (127 vs 212 min; p < 0.05). However, the last 10 robotic cases were performed in the same time span as the laparoscopic cases (136 vs 127 min). The total robotic setup time remained constant at about 30 min. There were no differences in postoperative complications between the two groups in terms of anastomotic leakage or stenosis. In the robotic group, more conversions to open surgery were noted. Early in the study, four patients (9%) had to undergo conversion to standard laparoscopic techniques due to inadequate setup of the robotic arms. Five patients (11%), however, had to undergo conversion to open surgery because of intestinal laceration during manipulation of the intestines with the robotic instruments. The costs were higher for robotic surgery than for standard laparoscopic RYGBP, mainly because of the extra equipment used, such as ultrasonic devices. CONCLUSION: The RYGBP procedure can be performed safely with the da Vinci robot after a learning curve of about 35 cases. At this writing, however, it is not clear whether the da Vinci system offers a real advantage over standard laparoscopic techniques.     

Beneficial Effect of Partial Portal Decompression Using the Inferior Mesenteric Vein for Intractable Gastroesophageal Variceal Bleeding in Patients With Liver Cirrhosis

BACKGROUND: Use of the inferior mesenteric vein (IMV) for partial portal decompression has not been recommended as a first-line option for intractable gastroesophageal variceal bleeding because of the thin diameter of the vein. Although these indications remain relevant, few reports have compared partial portal decompression using the IMV with other therapies. We propose that partial portal decompression using the IMV is a useful alternative treatment for intractable variceal bleeding. METHODS: We performed partial portal decompression using the IMV in eight patients with intractable variceal bleeding that had been uncontrolled using medical and endoscopic therapies. All patients were classified into Child's class B or C. The surgical data, morbidity, and mortality were assessed. RESULTS: Mean portal venous pressure significantly decreased from 26.9 +/- 2.0 mmHg before the surgery to 19.8 +/- 3.9 mmHg after the surgery. The operative mortality rate was 0%. The mean duration of hospital stay was 25.5 +/- 13.3 days. Although one patient experienced recurrent bleeding, shunt patency was well maintained in all patients during the follow-up period (mean 28.9 +/- 14.1 months). Six patients are still alive and well without ascites or hepatic encephalopathy. Two of the Child's class C patients who underwent emergency shunt died owing to hepatic decompensation. CONCLUSION: Partial portal decompression using the IMV can be a safe, effective way to treat intractable variceal bleeding in patients with liver cirrhosis. However, use of the shunt procedure may have the most survival benefits for cirrhotic patients with preserved liver function.     

The Sigma-trial protocol: a prospective double-blind multi-centre comparison of laparoscopic versus open elective sigmoid resection in patients with symptomatic diverticulitis

Backround  

Diverticulosis is a common disease in the western society with an incidence of 33–66%. 10–25% of these patients will develop diverticulitis. In order to prevent a high-risk acute operation it is advised to perform elective sigmoid resection after two episodes of diverticulitis in the elderly patient or after one episode in the younger (< 50 years) patient. Open sigmoid resection is still the gold standard, but laparoscopic colon resections seem to have certain advantages over open procedures. On the other hand, a double blind investigation has never been performed. The Sigma-trial is designed to evaluate the presumed advantages of laparoscopic over open sigmoid resections in patients with symptomatic diverticulitis.

Methodological considerations for a randomised controlled trial of podiatry care in rheumatoid arthritis: lessons from an exploratory trial

Background  

Whilst evidence exists to support the use of single treatments such as orthoses and footwear, the effectiveness of podiatry-led care as a complex intervention for patients with rheumatoid arthritis (RA) related foot problems is unknown. The aim of this study was to undertake an exploratory randomised controlled parallel arm clinical trial (RheumAFooT) to inform the design and implementation of a definitive trial and to understand the potential benefits of this care.
