Linear stapling of the short gastric vessels reduces blood loss and splenectomy at oesophageal and gastric surgery

Primary versus secondary splenic pedicle dissection in laparoscopic splenectomy for splenic diseases

BACKGROUND

Some areas of laparoscopic splenectomy (LS), such as the approach to splenic pedicle dissection, remain controversial. Here we recommend a technique for dissecting the secondary splenic pedicle vessels on the basis of analysis of retrospective data.

STUDY DESIGN

A retrospective review (April 2006 to October 2011) of databases at 2 institutions identified 136 patients who had undergone LS. In 34 patients with massive splenomegaly, primary splenic pedicle dissection technique (PSPD) had been used in 19 patients and secondary splenic pedicle dissection technique (SSPD) had been used in 15 patients. In 102 patients with normal-sized spleen or moderate splenomegaly, PSPD had been used in 56 patients and SSPD in 46 patients. We compared perioperative and follow-up data.

RESULTS

Laparoscopic splenectomy was completed in 128 patients. In the massive splenomegaly group, the conversion rate was 5.3% for PSPD and 33.3% for SSPD, the complication rate was 42.1% vs 20%, hospital stay was 3.2 ± 2.0 days vs 7.5 ± 3.5 days, and transfusion requirement was 1.1 ± 1.2 U vs 3.2 ± 0.9 U, respectively. However, in the normal or moderate splenomegaly group, except for complications, there were no significant differences between PSPD and SSPD techniques in perioperative findings. In the 2 groups, there were significant differences between the PSPD and SSPD techniques in pancreatic leakage (15.8% vs 0 and 8.9% vs 0, respectively) and postoperative fever (15.8% vs 6.7% and 10.7% vs 2.2%, respectively).

CONCLUSIONS

Secondary splenic pedicle dissection can decrease the incidence of splenic fever and pancreatic leakage and is a valuable technique for LS for normal-sized spleen or moderate splenomegaly. It is not a safe procedure for massive splenomegaly because of the high conversion rate.

Surgery for oesophageal cancer at Galway University Hospital 1993-2008

BACKGROUND

Surgical volume and outcome remain controversial in the management of oesophageal cancer.

AIMS

To assess the outcome of oesophagectomy for cancer at Galway University Hospital (GUH).

METHODS

Between 1994 and 2008, patients who underwent oesophagectomy were analysed.

RESULTS

During the study period, 126 oesophagectomies were performed for cancer. The average surgeon volume was 9 cases per year. The 30-day and overall in-hospital mortality rates were 6.3 and 7.9%, respectively. Restructuring of our critical care services has led to a reduction in 30-day mortality from 8.2 to 5.1%. The use of neoadjuvant chemoradiotherapy has increased from 17 to 35% during the study period. In patients who underwent resection, the 3 and 5-year overall survival rates were 45 and 29%, respectively.

CONCLUSIONS

Operative morbidity and mortality at GUH are comparable with worldwide outcomes. Improved resources and national restructuring of cancer services have significantly improved the quality of care and outcomes of patients.

Quantitative comparison of the difficulty of performing laparoscopic colectomy at different tumor locations

BACKGROUND

Laparoscopic approaches of colectomy for colonic cancer are increasingly surpassing the mainstream open colectomy approach. Impact of disease variables, such as tumor location, has not been adequately measured in quality improvement initiatives. Quantitative analysis concerning the difficulty performing these procedures and differences in postoperative care depending on tumor site will contribute to the development of training programs and to the assessment of quality of care strategies.

METHODS

A total of 3,765 cases received laparoscopic colectomy (LC). Patient demographics, weighted comorbidities, procedure-related complications, stapling devices, operating room (OR) time, postoperative length of hospital stay (LOS), or total charges (TC) were categorized and compared based on tumor location: cecum to ascending, transverse, descending, and sigmoid colon. Multivariate analyses determined the impact of tumor location on postoperative LOS, TC, OR time, and complications.

RESULTS

Sigmoid colon was the most frequent tumor placement (40.5%). Significant differences in age, gender, frequency of blood transfusion, use of stapling devices, OR time, and postoperative LOS were observed among tumor locations. Transverse colon was the most significant determinant of postoperative LOS and TC, whereas descending colon tumors correlated with increased OR time. Greater OR time was associated with more postoperative resource use and complications.

CONCLUSIONS

Tumor location, complications, and OR time affected postoperative resource use, whereas greater OR time signified an increased occurrence of complications. Developers of LC training programs or healthcare policy makers should consider the quantitative impact of tumor locations when attempting to improve effective skill training or to survey the quality of LC performance.

Effect of Hospital Characteristics on the Quality of Laparoscopic Gastrectomy in Japan

Background

Laparoscopic gastrectomy (LG) is becoming more widely indicated, although its application has not been investigated sufficiently in community-based gastrointestinal research because the small number of gastric cancers in western countries might have limited its use. However, concerns have been raised regarding variations in the quality of care with LG. To contribute to improving the efficient utilization of costly surgical innovations, we determined the impact of hospital characteristics on LG care.

Methods

Among 3,914 LG patients in 58 academic and 200 community hospitals between 2006 and 2008, we examined patient demographics, comorbidity, complications, partial or total gastrectomy, care process, hospital patient volume, hospital ownership and teaching status, and fiscal year. Hospital LG volume was divided into three quintile categories (lower volume, LV; intermediate volume, IV; or higher volume, HV) that consisted of an approximately equal number of patients. Dependent variables were operating time (OT), length of stay (LOS) and total charge (TC). The impact of hospital characteristics on these variables was assessed using multivariate analysis.

Results

Twenty-seven academic hospitals out of 193 LV hospitals treated 271 (21%) LG patients, 20 of 44 IV hospitals treated 596 (47%), and 11 of 21 HV hospitals treated 748 (55%). Although mortality or complications did not vary significantly between LV, IV and HV hospitals, the latter were associated with longer OT or LOS and more TC. More blood transfusions were required in HV hospitals once indicated. Hospital ownership or teaching status did not explain the variation in complications. Teaching and national hospitals consumed more resources, and municipal and private hospitals reduced OT more than national hospitals.

Conclusions

A volume-quality relationship was recognized. As intraoperative transfusion prolongs OT and results in more complications, clinical societies or policy makers should introduce this new technique concurrently with quality improvement initiatives that aim to reduce unnecessary OT at targeted institutions. Hospitals varied in terms of LOS and TC, therefore, policy makers should also monitor resource utilization to enhance the efficiency of LG care under restrictive fiscal policies.

Impact of hospital case volume on the quality of laparoscopic colectomy in Japan

INTRODUCTION

The increased use of laparoscopic colectomy for colon cancer requires the evaluation of hospital case volume, quality care, and training systems, considering the difficulty of this surgery for various tumor locations.

MATERIALS AND METHODS

We assessed the quality of this procedure in Japan, based on hospital case volume and tumor location. A total of 3,765 patients were enrolled across 567 hospitals between July and December 2007. We analyzed patient characteristics, postoperative surgical complications, the administration of stapling devices or chemotherapy, hospital volume and teaching status, postoperative length of stay, total charges, and operating room time. Hospitals were classified into four case-volume categories: high (> or =5 cases per month), intermediate to high (3-4), low to intermediate (1-2), and low (<1). Multivariate analysis was used to test the impact of hospital category and tumor location.

RESULTS

Ten high-volume hospitals performed 401 cases, while 355 low-volume hospitals did 903. Hospital case volume, operating time, and complications affected postoperative stay and total costs. Longer procedural time was an independent predictor of complications. Tumor location, case volume, and teaching status explained the variations in procedural time individually but not complications. Training systems highlighting the applicability of techniques are important to promote the quality of laparoscopic colectomy.
