RESUMO
BACKGROUND: Treatment for diverticular disease has evolved over time. In the United States, there has been a trend towards minimally invasive surgical approaches and fewer postoperative complications, but no study has investigated this subject in the Veterans Health Administration. METHODS: This retrospective review identified patients undergoing elective surgery for diverticular disease from 2004 to 2018. Demographics, comorbidities, operative approach, rates of ostomy creation, and 30-day outcomes were compared. The 15-year time period was divided into 3-year increments to assess changes over time. RESULTS: 4198 patients were identified. Complication rate decreased significantly over time (28.1%-15.7%, p < 0.001), as did infectious complications (21.5-6.3%, p < 0.001). Median hospital length-of-stay decreased from 7 to 5 days (p < 0.001). Rates of laparoscopic surgery increased over time (17.7%-48.1%, p < 0.001). CONCLUSIONS: Increased utilization of laparoscopy in veterans undergoing elective surgery for diverticular disease coincided with fewer complications and a shorter length-of-stay. These trends mirror outcomes reported in non-veterans.

BACKGROUND: Robotic surgery has increased in recent years for the treatment of colorectal cancer; however, it is not yet the standard of care. This study aims to compare the 30-day outcomes after robotic colectomy for right-sided colon cancer from our institution with those from a national dataset, the targeted colectomy American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database. METHODS: Patients undergoing elective, robotic, right colon resection for stage I, II, and III colon cancer were identified within the targeted colectomy ACS-NSQIP database from 2012 to 2014. Patients meeting the same criteria were identified within a prospectively maintained institutional database from 2009 to 2015. Univariate analyses using chi-square tests and Student's t-tests were done where appropriate to compare baseline characteristics and outcomes between the two groups. RESULTS: Patients at our institution had a significantly higher average number of lymph nodes retrieved (24.4 versus 20.1, P = .046). There was no statistically significant difference between the two groups regarding the incidence of wound infections, anastomotic leaks, blood transfusions, unplanned return to the operating room, or prolonged length of hospital stay. There were no 30-day mortalities at our institution and only one in the ACS-NSQIP database. CONCLUSIONS: Our institutional experience with robotic right colon resection is equivalent to that of a national sample. This study demonstrates the safety of performing robotic right hemicolectomy for the treatment of colon cancer.

BACKGROUND: Using synthetic mesh to buttress the crural repair during laparoscopic hiatal hernia repair may be associated with dysphagia and esophageal erosions, while a biologic mesh is expensive and does not decrease long-term recurrence rates. This study documents outcomes of laparoscopic paraesophageal hernia repairs using the falciform ligament to reinforce the crural repair. METHODS: This is a prospective study of laparoscopic paraesophageal hernia repairs with a falciform ligament buttress. Preoperatively and at 6 and 12 months postoperatively, medications, radiologic studies, and symptom severity and frequency scores were recorded. Patients with a hiatal defect greater than 5 cm were included, while patients with recurrent hiatal hernia repairs or prior gastric surgery were excluded. Symptom scores were compared pre- and postoperatively with a p < 0.05 considered significant. RESULTS: One hundred four patients were included with a mean age of 62.4 years, and 57 patients underwent an upper gastrointestinal series at least 12 months from the initial operation with a mean follow-up of 20.6 months. The mean symptom severity score decreased from 14.32 ± 0.93 to 4.75 ± 0.97 (p < 0.001), mean symptom frequency score decreased from 14.99 ± 0.97 to 5.25 ± 0.99 (p < 0.001), and mean total symptom score decreased from 29.31 ± 1.88 to 10.00 ± 1.95 (p < 0.001). Five patients developed recurrent hiatal hernias on upper gastrointestinal series, but only three required operative intervention. CONCLUSIONS: Laparoscopic paraesophageal hernia repair with a falciform ligament buttress is a viable option for a durable closure. Ongoing follow-up will continue to illuminate the value of this approach to decrease morbidity and recurrence rates for hiatal hernia repair.

BACKGROUND: Morbidly obese patients are at risk for nonalcoholic steatohepatitis (NASH) even in the absence of risk factors for liver disease. Unfortunately, NASH is usually not clinically evident, and a definitive, noninvasive test for NASH does not exist. Resistin, a cytokine originating from adipose tissue, is involved in insulin resistance and also initiates proinflammatory signaling from hepatic stellate cells. This study explores the relationship between resistin expression and liver pathology in bariatric surgery patients. METHODS: Blood samples from 30 patients undergoing bariatric surgery were collected. Total RNA was extracted and cDNA was synthesized. Quantitative RT-PCR was used to quantify relative gene expression using 18s rRNA gene as an internal control. Wedge liver biopsies from these patients were sectioned and stained. Based on a previously published scoring method, biopsies were assigned an overall NASH severity score and subscores for steatosis, inflammation, and fibrosis. Results were analyzed by using Student's t test. RESULTS: Resistin mRNA levels ranged from 0.5 to 9.7. A group of five patients with very high resistin expression (>4) was identified. These patients had a significantly higher average NASH score compared with the rest of the group (7.9 vs. 4.48, p = 0.019). Steatosis and inflammation scores were significantly higher in the high-resistin group (p < 0.05 for both comparisons). There also was a trend toward higher fibrosis score in this group, which approached statistical significance (p = 0.051). CONCLUSIONS: In morbidly obese patients, high resistin expression in serum is associated with hepatic steatosis, inflammation, and fibrosis. The development of elevated resistin expression may represent a link between obesity and the onset of steatohepatitis.

Squamous cell carcinoma (SCC) spreads through direct extension, lymphatic vessels, and, rarely, hematogenous routes. The most common malignancies to metastasize to the spleen include carcinomas of the breast, lung, and melanoma. We present an unusual case of SCC of the neck with splenic metastases. The patient presented with a primary solid tumor of the neck that extended into the surrounding soft tissues, including the internal jugular vein and regional lymph nodes. A metastatic work-up with a positron emission tomograph showed enhancement in the left upper quadrant. A computed tomograph (CT) was then performed. The CT revealed three distinct splenic lesions, the largest measuring 6x6.5x2.5 cm. Subsequently, the patient was scheduled for a splenectomy. At the time of operation, diagnostic laparoscopy revealed only the splenic lesions. A laparoscopic splenectomy was performed successfully and the patient was started on a regular diet on postoperative day 1. This paper describes the first documented case of SCC of the neck with splenic metastases. The lesion was diagnosed and treated laparoscopically. The case is described in detail along with the clinical implications of this rare finding.
