Single-incision laparoscopic cholecystectomy at community hospitals in Honolulu, Hawai'i: a case series.

This study aims to demonstrate the feasibility of implementing single-incision laparoscopic cholecystectomy in a community hospital setting. Minimally invasive surgical approaches for cholecystectomy achieve equivalent outcomes to the open surgical approach with less post-operative pain, improved cosmesis, shorter hospital stays, and decreased complications. Surgeons are attempting to reduce incisional trauma further by decreasing the number of incisions. A retrospective chart review was conducted for demographics, operating time, blood loss, conversion rate, length of stay, and presence of operative complications on patients undergoing single-incision laparoscopic cholecystectomy at two community hospitals between 2008 and 2011. One hundred and three patients (79 females and 24 males) underwent single-incision laparoscopic cholecystectomy. The mean age was 49.8 years (range 18-88). Ninety-six patients (93.2%) underwent elective procedures while 7 patients (6.8%) underwent urgent procedures. The mean operating time was 89.7 (± 28.3) minutes and the average blood loss was 33.7 (± 27.4) milliliters. Ninety-five (92.2%) of the procedures were successfully completed with a single-incision approach and 8 (7.8%) were converted to a multi-incisional approach, while none were converted to an open approach. The median length of stay was 4.75 hours. The post-operative complication rate was 7.4% (7/95) and included four superficial wound infections, one bile leak, one acute renal failure, and one urinary tract infection. These outcomes for single-incision laparoscopic cholecystectomy are comparable to other case series reported in the literature, and this retrospective review illustrates that single-incision laparoscopic cholecystectomy is feasible in a community setting.

Prescription drug cost reduction in Native Hawaiians after laparoscopic Roux-en-y gastric bypass.

OBJECTIVE: Native Hawaiians (NH) represent a unique population where socioeconomic factors have contributed to higher incidence rates of obesity and related comorbidities than in the general population resulting in substantial prescription medication costs. Studies demonstrate that laparoscopic Roux-en-y gastric bypass (LRYGB) surgery results in significant weight loss, improvement of comorbidities, and decreased costs for prescription medications in Caucasians. This study aimed to analyze the effects of LRYGB surgery on Native Hawaiians and their prescription drug costs. METHODS: Demographics, baseline body mass index (BMI), comorbidities, preoperative, and postoperative data were analyzed for NH patients who underwent LRYGB between January 2004 and April 2009. Medication costs were determined using the online pharmacy . Generic drugs were selected when appropriate, while vitamins and nutritional supplements were not included in this study. RESULTS: Fifty (14 Men, 36 women) NH patients had sufficient data and follow-up for analysis. Average preoperative BMI was 49 kg/m(2), while at one year follow-up it decreased to 33 kg/m(2) (P<.001). This correlates to an average of 61% excess body weight lost (P<.001). The average number of prescription medications decreased from 3.5/patient preoperatively to 1.1/patient at one year (P<.001), equating to a monthly cost savings of US $195.8/patient (P<.001). CONCLUSIONS: LRYGB provided substantial weight loss for morbidly obese NH patients, resulting in significantly less prescription medication use and substantial cost savings. Thus, bariatric surgery for weight management has the potential to improve the overall well-being and lower the financial burden of medical care in socioeconomically disadvantaged communities such as the NH.

Novel technique for preoperative localization of colorectal tumors for laparoscopic resection.

Minimally invasive surgery for resection of colon tumors is being utilized with increasing frequency making accurate preoperative tumor localization essential to proper surgical planning and patient positioning. Traditional endoscopic localization techniques such as lesion distancing from the anal verge are adequate in the majority of patients. Patients with a significantly tortuous and redundant colon, however, are at increased risk for ambiguous and incorrect lesion localization. The use of endoscopic submucosal marking by injection to tattoo the site of interest may increase the accuracy of tumor localization, but its efficacy can be technique dependent. We present a novel technique for endoscopic tumor localization using endoscopic clip placement, followed by immediate abdominal radiograph, to accurately locate a colonic lesion in preparation for laparoscopic colonic resection.

Long-term follow-up outcome of patients undergoing radiofrequency ablation for unresectable hepatocellular carcinoma.

The long-term outcome of radiofrequency thermal ablation (RFA) for unresectable hepatocellular carcinoma (HCC) has not been reported. This study was performed to evaluate the long-term survival of patients with unresectable HCC after RFA and to identify possible factors that might affect survival. In this prospective study, 65 patients with unresectable HCC who underwent RFA were followed. A total of 84 RFA operations were performed percutaneously (n = 49), laparoscopically (n = 20), or by open surgery (n = 15), to ablate 191 tumors. Twenty-two patients died within 16 months; otherwise, the follow-up period was at least 16 months, up to 71 months, with median 20.0 months and mean (+/- standard deviation) 24.8 +/- 18.4 months for all patients. Local tumor recurrence developed in 12 of 191 tumors (6.3%) in 11 of 84 operations (13.1%), or 11 of 65 patients (16.9%). New liver and/or extrahepatic recurrence developed in 48 operations (57.1%). The overall median, mean, and 5-year survivals were 40.0 months, 33.7 +/- 2.9 months, and 39.9%. The disease-free survivals were 16.0 month, 32.9 +/- 3.0 months, and 27.9%. Factors that had a significant effect on survival outcome after RFA were TNM cancer stage and the operative approach method employed for RFA. Age, gender, race, etiology, alpha-fetoprotein, previous or subsequent treatment, and liver function (Child-Pugh class) did not affect survival. For patients with unresectable HCC, RFA is an effective and repeatable local treatment that can afford long-term survival, although often with disease recurrence.
