The trend towards minimally invasive surgery (MIS) for endometrial cancer: an ACS-NSQIP evaluation of surgical outcomes.

OBJECTIVE: Our objective was to evaluate the surgical trend towards increased MIS in the management of endometrial cancer in regard to improvements in patient outcomes. METHODS: Using the American College of Surgeons-National Surgical Quality Improvement Project's database, patients who underwent hysterectomy for endometrial cancer from 2006-2010 were identified and categorized into exploratory laparotomy (XLAP) or MIS. Comparative analyses were performed and stratified by year of surgery to evaluate demographics, surgical outcomes, and 30-day surgical morbidity. RESULTS: A total of 2076 patients (1269 XLAP and 807 MIS) underwent hysterectomy for endometrial cancer between 2006 and 2010. Longer operative times were seen in MIS compared to XLAP (192 vs. 148 min; p<0.001) as well as significant increase in mean hospital stay in the XLAP group of 3.8 days compared to 1.6 days in MIS (p<0.0001). When controlling for preoperative comorbidities, significant increases in postoperative complications were observed in XLAP compared to MIS group (total 396 vs. 91; p<0.0001). MIS increased from 16% in 2006 to 48% in 2010, which correlated to decreases in complications and hospital stays. Each 10% increase in MIS would save $2.8 million and 41 postoperative complications. If used exclusively, MIS would save 6434 hospital days and 416 complications. CONCLUSIONS: Despite increases in operative times, MIS for the treatment of endometrial cancer significantly reduces perioperative complications and hospital stay. Considering the improvements in patient outcomes and the potential savings to the health care system, MIS should be the preferred route for the surgical treatment of this disease when feasible.

Treatment of intra-abdominal abscesses in Crohn's disease: a nationwide analysis of patterns and outcomes of care.

BACKGROUND: Abdominal abscesses are a common complication in Crohn's disease (CD). Percutaneous drainage of such abscesses has become increasingly popular and may deliver outcomes comparable to surgical treatment; however, such comparative data are limited from single-center studies. There have been no nationally representative studies comparing different treatment modalities for abdominal abscesses. METHODS: We identified all adult CD-related non-elective hospitalizations from the Nationwide Inpatient Sample 2007 that were complicated by an intra-abdominal abscess. Treatment modality was categorized into 3 strata-medical treatment alone, percutaneous drainage, and surgery. We analyzed the nationwide patterns in the treatment and outcomes of each treatment modality and examined for patient demographic, disease, or hospital-related disparities in treatment and outcome. RESULTS: There were an estimated 3,296 hospitalizations for abdominal abscesses in patients with CD. Approximately 39 % were treated by medical treatment alone, 29 % with percutaneous drainage, and 32 % with surgery with a significant increase in the use of percutaneous drainage since 1998 (7 %). Comorbidity burden, admission to a teaching hospital, and complicated Crohn's disease (fistulae, stricture) were associated with non-medical treatment. Use of percutaneous drainage was more common in teaching hospitals. Mean time to percutaneous drainage and surgical treatment were 4.6 and 3.3 days, respectively, and early intervention was associated with significantly shorter hospitalization. CONCLUSIONS: We describe the nationwide pattern in the treatment of abdominal abscesses and demonstrate an increase in the use of percutaneous drainage for the treatment of this subgroup. Early treatment intervention was predictive of shorter hospitalization.

Endografting increases total volume of AAA repairs but not at the expense of open surgery: experience in more than 1000 patients.

PURPOSE: To compare the volume of open graft replacements (OGR) for abdominal aortic aneurysm (AAA) versus endovascular aneurysm repairs (EVAR) over time and after modifying selection criteria. METHODS: A review was conducted of 1021 consecutive patients who underwent AAA repair from 1989 through 2002: 496 elective OGRs for infrarenal AAAs (STANDARD), 289 elective EVARs for infrarenal AAAs, 59 complex OGRs for suprarenal AAAs, and 177 emergent OGRs for ruptured AAAs. Patients from 1995 to 2002 were divided into 2 groups based on shifting treatment strategies; 454 patients were treated by STANDARD or EVAR at the surgeon's discretion between 1995 and 2000 (post EVAR). The second group comprised 161 patients treated in 2001-2002 after the introduction of "high-risk" screening criteria (age > or = 72 years, diabetes mellitus, renal dysfunction, impaired pulmonary function, or ASA class IV) that dictated EVAR whenever anatomically feasible. For comparison, 170 STANDARD repairs performed in the 6 years prior to EVAR served as a control. RESULTS: While surgery for ruptured AAAs remained fairly stable over the 14-year period, the number of patients undergoing elective repair increased due to the implementation of EVAR. During the 6 years after its introduction, EVAR averaged 34.3 patients per year; after 2001, the annual frequency of EVAR increased to 41.5 (p > 0.05). In like fashion, the rate of STANDARD repairs increased to 41.3 patients per year versus 28.3 before EVAR (p = 0.032). ASA class IV patients increased by almost 9 fold in the recent period versus pre EVAR (p = 0.006). The overall mortality after elective infrarenal AAA repair decreased between the pre and post EVAR periods (6.5% versus 3.7%, p > 0.05) and fell still further to 1.2% in the most recent period (p = 0.021 versus pre EVAR). CONCLUSIONS: The implementation of an EVAR program increases the total volume of AAA repairs but does not reduce open surgical procedures. By allocating patients to EVAR or open repair based their risk factors, mortality was markedly reduced.

What did the laparoscopic Nissen approach of the gastro-oesophageal reflux really change for the patients 8 years later?

BACKGROUND: Nissen fundoplication (NF) is recognized as the surgical treatment of the gastro-oesophageal reflux disease (GERD). NF can be achieved either by open surgery or by laparoscopic approach. METHODS: From 1987 to 1997, 210 patients were treated for GERD by NF: 61 by open and 149 by laparoscopic approach. All the patients were followed more than 1 year and were scored by clinical assessment (Visick scale adaptation). In case of Visick score > 1, GI-endoscopy, X-ray series or 24-hour pH-study complete the evaluation. RESULTS: The operative time was comparable between both groups. The postoperative recovery was statistically faster in the laparoscopic group (p = 0.0001). The mean time of follow-up was 6 years after open NF and 4 years after laparoscopic NF. After open NF or laparoscopic NF, 72% and 67% of the patients are respectively scored Visick 1, 13% and 21%--Visick 2, 6.8% and 6%--Visick 3 and 8.2% and 6%--Visick 4 (NS). Patients with recurrence of GERD were scored Visick 4, so failure of the surgical treatment is observed in 5 patients after open NF and 9 patients after laparoscopic NF. The occurrence of incisional hernia was significantly higher in the open group (p = 0.0001). CONCLUSION: NF remains a safe procedure for surgical treatment of GERD and can be achieved by laparoscopic approach with comparable results to those by open laparotomy. In our experience, the advantages of the laparoscopic approach is a faster postoperative recovery and a lower risk of incisional hernia.

Abdominal closure.

There have been considerable developments in abdominal closure over the past 30 years or so, and (happily for some of the poorer countries of the world) they have not largely involved undue expense. Indeed many of the developments are compatible with considerable cost-saving. I have changed over from the traditional (as it was then) method of multilayer closure with catgut to a one-layer method with monofilament nylon (often fishing nylon) in 1971. Since that time, despite a previous unhappy experience with the upper abdominal paramedian closure, I have not had a single 'burst abdomen' in any adult patients since making that change.
