Reintervention Rate After Pigtail Catheter Insertion Compared to Surgical Chest Tubes.

BACKGROUND: Prior studies suggest similar efficacy between large-bore chest tube (CT) placement and small-bore pigtail catheter (PC) placement for the treatment of pleural space processes. This study examined reintervention rates of CT and PC in patients with pneumothorax, hemothorax, and pleural effusion. METHODS: This retrospective study examined patients from September 2015 through December 2020. Patients were identified using ICD codes for pneumothorax, hemothorax, or pleural effusion. Use of a pigtail catheter (≤14Fr) or surgical chest tube (≥20Fr) was noted. The primary outcome was overall reintervention rate within 30 days of tube insertion. Patients who died with a pleural drainage catheter in place, unrelated to complications from chest tube placement, were excluded. RESULTS: There were 1032 total patients in the study: 706 CT patients and 326 PC patients. The PC group was older with more comorbidities and more likely to have effusion as the indication for pleural drainage. Patients with PC were 2.35 times more likely to have the tube replaced or repositioned (P < .0001), 1.77 times more likely to require any reintervention (P = .001) and 2.09 times more likely to remain in the hospital >14 days (P < .0001) compared to patients with CT. CONCLUSION: PCs have a significantly higher reintervention rate compared to CT for the treatment of pneumothorax, hemothorax, and pleural effusion. Although PC are believed to cause less pain and tissue trauma, they do not necessarily drain the pleural space as well as CT. Decisions on which method of draining the chest should be made on a case-by-case basis.

Plasma Cell Vulvitis: A Systematic Review.

OBJECTIVE: This systematic review aimed to present the available literature on plasma cell vulvitis (PCV), a relatively uncommon form of inflammatory vulvovaginal dermatitis. MATERIALS AND METHODS: A literature search was performed in PubMed, Science Direct, and Google Scholar using the following key words: "plasma cell vulvitis," "Zoon vulvitis," and "vulvitis circumscripta plasmacellularis." Specific variables were assessed in each article, including patient age, menopausal status, comorbidities, presenting symptoms, symptom duration, histological description, treatment, and treatment response. RESULTS: Thirty-nine articles met inclusion criteria, including 38 case reports and 1 observational study, with a total of 96 cases of PCV reported. The mean age of diagnosis was 52.9 years, with an age range of 8-76 years. Most common presenting symptoms included pruritis and vaginal discomfort, with average duration of symptoms 28.2 months (range = 2 months to 10 years). All reports demonstrated subepithelial plasma cell infiltrate on histology. Five percent of PCV cases reported concomitant autoimmune conditions and 6% sexually transmitted infections. Most common treatment modalities included topical corticosteroids (n = 41), tacrolimus (n = 6), and imiquimod (n = 6). In 53 reported outcomes, 88.7% of patients had resolution of symptoms with treatment. CONCLUSIONS: Clinical research is needed to better determine the diagnostic criteria and to assess the efficacy of treatment options for PCV.

Trends in utilization, conversion rates, and outcomes for minimally invasive approaches to non-metastatic rectal cancer: a national cancer database analysis.

BACKGROUND: This study examined utilization and conversion rates for robotic and laparoscopic approaches to non-metastatic rectal cancer. Secondary aims were to examine short- and long-term outcomes of patients who underwent conversion to laparotomy from each approach. METHODS: The National Cancer Database (NCDB) was reviewed for all cases of non-metastatic adenocarcinoma of the rectum or rectosigmoid junction who underwent surgical resection from 2010 to 2016. Utilization rates of robotic, laparoscopic, and open approaches were examined. Patients were split into cohorts by approach. Subgroup analyses were performed by primary tumor site and surgical procedure. Multivariable analysis was performed by multivariable logistic regression for binary outcomes and multivariable general linear models for continuous outcomes. Survival analysis was performed by Kaplan-Meier and multivariable cox-proportional hazards regression. RESULTS: From 2010 to 2016, there was a statistically significant increase in utilization of the robotic and laparoscopic approaches over the study period and a statistically significant decrease in utilization of the open approach. The conversion rates for robotic and laparoscopic cohorts were 7.0% and 15.7%, p < 0.0001. Subgroup analysis revealed statistically lower conversion rates between robotic and laparoscopic approaches for rectosigmoid and rectal tumors and for LAR and APR. Converted cohorts had statistically significant higher odds of short term mortality than the non-converted cohorts (p < 0.05).Laparoscopic conversion had statistically higher odds of positive margins (p < 0.0001) and 30-day unplanned readmission (p < 0.0001) than the laparoscopic non-conversion. Increased adjusted mortality hazard was seen for converted laparoscopy relative to non-converted laparoscopy (p = 0.0019). CONCLUSION: From 2010 to 2016, there was a significant increase in utilization of minimally invasive approaches to surgical management of non-metastatic rectal cancer. A robotic approach demonstrated decreased conversion rates than a laparoscopic approach at the rectosigmoid junction and rectum and for LAR and APR. Improved outcomes were seen in the minimally invasive cohorts compared to those that converted to laparotomy.
