Laparoscopic Hartmann’s procedure for fecal peritonitis resulting from perforation of the left-sided colon in elderly and severely ill patients

Background

Traditional treatment for fecal peritonitis resulting from perforation of the left-sided colon has been performed using Hartmann??s procedure to reduce the high mortality caused by anastomotic leakage. However, the morbidity rates associated with abdominal incision (due in great part to wound infection, and dehiscence of abdominal fascia) are high. Therefore, we propose using laparoscopic Hartmann??s procedure with abdominal incisions only for the port site to reduce the high morbidity associated with the laparoscopic procedure as compared to open surgery.

Methods

Between April 2008 and July 2011, we treated 16 consecutive patients (median age, 83?years) with fecal peritonitis resulting from perforations in the left-sided colon due to various causes. The American Society of Anesthesiologists score of each patient was either IV or V. Patients underwent a four-port laparoscopic Hartmann??s procedure. Specimens were extracted through the stoma site. Irrigation of the abdominal cavity with more than 10?L of saline was performed in every case, as was insertion of three 10-mm silicon drains via the port site into the left- and right subphrenic spaces or the pouch of Douglas.

Results

The median total surgical time was 166?min (range, 123?C250?min). There were no intraoperative complications, and there was no need to convert to open surgery. Fourteen patients survived. There was no wound infection or dehiscence of abdominal fascia. Successful laparoscopic reversals of the laparoscopic Hartmann??s procedure were performed in all 14 survivors.

Conclusions

This laparoscopic Hartmann??s procedure is a promising surgical strategy for treating fecal peritonitis arising from perforation of the left-sided colon.     

Comparison of the diagnostic power of transthoracic and transesophageal echocardiography to detect ruptured chordae tendineae

Preoperative information concerning the severity and etiology of MR is very important for selecting the most appropriate surgical strategy. Ruptured chordae tendineae (RCT) are one of the most important preoperative findings. We compared the diagnostic power of transesophageal echocardiography (TEE) and transthoracic echocardiography (TTE) to detect RCT in patients with MR. We studied 61 patients with MR (30 men, 31 women; mean age, 61 ± 12 years) who underwent mitral valve repair or replacement. Both TTE and TEE were performed before the operations, and the sensitivity and specificity of TTE and TEE to detect RCT were determined. In addition, other factors that influenced the detection of RCT by these two methods were investigated. At the time of an operation, RCT was confirmed in 39 of 61 cases. Transesophageal echocardiography had a higher sensitivity than TTE (74% versus 44%; P = 0.006) to detect RCT, although the specificity was not significantly different. In patients with a body mass index (BMI) > 22 (P = 0.023) or MR grade 4 (P = 0.026), TEE had a significantly higher diagnostic sensitivity than TTE, although there was no significant difference in patients with BMI < 22 or MR grade ≤ 3. In the lateral and medial segments of the mitral valve, TEE had a significantly higher diagnostic sensitivity to detect RCT than TTE (P = 0.0012), although there was no significant difference in the middle segments. There was no significant difference between TTE and TEE with respect to the sensitivity to detect RCT in myxomatous mitral valves. Although the sensitivity of TEE was higher than that of TTE to detect RCT, it was affected by BMI, MR grade, the RCT-presenting segments, and the etiology of MR.     

Fall Risk Index predicts functional decline regardless of fall experiences among community‐dwelling elderly

Aim: The 21‐item Fall Risk Index (FRI‐21) has been used to detect elderly persons at risk for falls. The aim of this longitudinal study was to evaluate the FRI‐21 as a predictor of decline in basic activities of daily living (BADL) among Japanese community‐dwelling elderly persons independent of fall risk. Methods: The study population consisted of 518 elderly participants aged 65 years and older who were BADL independent at baseline in Tosa, Japan. We examined risk factors for BADL decline from 2008 to 2009 by multiple logistic regression analysis on the FRI‐21 and other functional status measures in all participants. We carried out the same analysis in selected participants who had no experience of falls to remove the effect of falls. Results: A total of 45 of 518 participants showed decline in BADL within 1 year. Multivariate logistic regression analysis showed that age (odds ratio [OR] 1.13, 95% confidence interval [CI] 1.05–1.20), FRI‐21 ≥ 10 (OR 3.81, 95% CI 1.49–9.27), intellectual activity dependence (OR 3.25, 95% CI 1.42–7.44) and history of osteoarthropathy (OR 3.17, 95% CI 1.40–7.21) were significant independent risk factors for BADL decline within 1 year. FRI‐21 ≥ 10 and intellectual activity dependence (≤3) remained significant predictors, even in selected non‐fallers. Conclusion: FRI‐21 ≥ 10 and intellectual activity dependence were significant predictive factors of BADL decline, regardless of fall experience, after adjustment for confounding variables. The FRI‐21 is a brief, useful tool not only for predicting falls, but also future decline in functional ability in community‐dwelling elderly persons. Geriatr Gerontol Int 2012; ??: ??–?? .     

Sclerosing encapsulating peritonitis after living donor liver transplantation: a case successfully treated with tamoxifen: report of a case

Sclerosing encapsulating peritonitis (SEP) is a rare cause of bowel obstruction. It is difficult to diagnose and the prognosis is poor. This report describes a case of SEP after living donor liver transplantation that was successfully treated with tamoxifen. A 56-year-old male, that had received a liver transplant for hepatitis C virus-related hepatocellular carcinoma 5 years earlier, was admitted with continuous abdominal pain and nausea. He had increased C-reactive protein levels and white blood cell count, and underwent laparotomy 5 days after hospitalization. The surgical findings showed ascites and SEP of the small bowel. An attempt to peel off the adhesions was stopped because there was a strong risk of intestinal tract damage. Tamoxifen treatment was initiated for SEP after surgery. The patient’s symptoms gradually improved and he was able to resume feeding. He had been symptom-free for over 3 years at the last follow-up.     

A newly designed bioabsorbable substitute for the treatment of diaphragmatic defects

Purpose

Earlier studies have investigated the suitability of various materials and autologous grafts for the repair of diaphragmatic defects. Our group investigated the feasibility of using an artificial diaphragm (AD) to repair wide diaphragmatic defects.

Methods

Twelve pigs were laparotomized and, in each pig, a defect was fashioned by resecting a round 8-cm diameter hole in the left diaphragm. Next, the defect was repaired by implanting an AD. The animals were relaparotomized 8 or 24 weeks after implantation for gross, histological and radiological observation of the implanted sites.

Results

All recipient animals survived until killing for evaluation. Chest X-ray examinations showed no differences between the preoperative diaphragms and the grafted diaphragms at 8 and 24 weeks after implantation. At 8 weeks after implantation, the implanted sites exhibited fibrous adhesions to the liver and lungs without deformities or penetrations. Parts of the surface tissue at the graft sites had a varnished appearance similar to those of the native diaphragm. Histology performed at 8 weeks detected no trace of the ADs in the graft sites; however, numerous inflammatory cells and profuse fibrous connective tissue were observed. At 24 weeks after implantation, no differences were found in the thorax between the areas with the grafts and the unaffected areas. Histology of the graft sites in the thorax confirmed growth of mesothelial cells similar to that observed in the native diaphragm.

Conclusions

Artificial diaphragms can be a novel substitute for diaphragmatic repair.     

Manserin as a novel histochemical neuroendocrine marker in prostate cancer

ObjectivesTo investigate the presence of manserin in human prostate cancers and to correlate manserin expression with pathologic outcomes and progression-free survival.MethodsEighty-seven patients with recent prostate cancer were classified into 4 groups based on Gleason score, and manserin immunohistochemistry was correlated with Gleason sum grade. To investigate the validity of manserin as a prognostic factor, the Cox proportional hazards regression model was performed on 48 patients in our cohort with T3 or T4 prostate cancer who were initially treated with androgen deprivation therapy.ResultsThe manserin-positive rates of patients with Gleason sums of 6, 7, 8, and ≥9 were 0%, 20.0%, 35.0%, and 48.1%, respectively. Manserin-positive rates were positively correlated with Gleason sums (P = 0.0001). Median times to cancer progression in groups with (n = 8) and without (n = 40) manserin expression were 8 months and 28 months, respectively (P = 0.01). Univariate Cox analysis revealed that manserin expression, clinical stage T4, and high Gleason sum were significantly associated with progression. Multivariate analysis revealed that only 2 factors, manserin expression (hazard ratio (HR) 4.99, P = 0.01) and clinical stage T4 (HR 4.77, P = 0.03), were independent risk factors for progression.ConclusionsThis is the first report of manserin expression in human prostate cancers. Manserin may serve as a marker of prostate cancer progression.
