RESUMEN

Despite the steady decline in the incidence of colorectal cancer (CRC) and cancer-related mortality in Americans of 50 years and older over the last few decades, there has been a disturbing trend of steadily rising incidence in early-onset colorectal cancer (EOCRC), defined as CRC in those younger than 50 years. With the incidence of EOCRC increasing from 4.8 per 100,000 in 1988 to 8.0 per 100,000 in 2015, and with the decreased rates in those older than 50 years largely attributed to improved screening in the older population, new screening recommendations have recently lowered the age for screening average-risk individuals from 50 to 45. EOCRC has been found to present differently from late-onset CRC, with a higher proportion of patients presenting with left-sided and rectal cancer, more aggressive histological features, and more advanced stage at the time of diagnosis. This article reviews the most recent evidence from population-based studies and institutional series, as well as the newest screening guidelines, and provides an up-to-date summary of our current understanding of EOCRC, from clinical presentation to tumor biology and prognosis, and future directions in treatment and prevention.

RESUMEN

AIM: Hartmann's procedure is commonly performed emergently for infectious, inflammatory, or malignant processes. Most patients historically do not undergo reversal, and those who do have been found to suffer significant morbidity. The aim of this study was to study factors associated with complications after Hartmann's reversal and to provide information and guidance to surgeons. METHOD: A retrospective review of patients undergoing Hartmann's reversal between May 2002 and October 2017 was conducted at a tertiary medical center. Data included patient characteristics at the time of surgery and intra- and postoperative complications. Chi-square test was used for categorical variables. The Wilcoxon signed rank or t test where appropriate was used for multivariate analysis. RESULTS: Two hundred forty-nine patients were included. Mean age at reversal was 58.8 years, and 114 (58%) were male. Sixty-two (31.8%) patients experienced a major complication following reversal. Eight (4%) patients had an anastomotic leak. Thirteen (6.67%) patients had an intra-abdominal abscess which required either IR or operative drainage. Patients who experienced a major complication were more likely to have an ASA 4 at time of reversal (14.3% vs. 4.24%, p = 0.019), liver disease (6.6% vs. 0.8%, p = 0.021), and BMI < 30 (35% vs. 17.3%, p = 0.020). CONCLUSIONS: Nearly one-third of patients who had reversal surgery experienced a major complication. Four percent of patients undergoing reversal had an anastomotic leak, comparable to previously reported rates. Patients with ASA 4, liver disease, and BMI < 30 were at higher risk of a major complication following reversal. Patients who underwent laparoscopic reversal had no significant difference in outcomes. AIM: What does this paper add to the literature? The decision of whether to reverse a colostomy after Hartmann's procedure. Our study aims to identify risk factors associated with complications after Hartmann's reversal to better guide surgeon's facing the dilemma of whether or not to reverse the stoma.

RESUMEN

BACKGROUND: Abdominoperineal resection (APR) is primarily used for rectal cancer and is associated with a high rate of complications. Though the majority of APRs are performed as open procedures, laparoscopic APRs have become more popular. The differences in short-term complications between open and laparoscopic APR are poorly characterized. METHODS: We conducted a retrospective cohort study using the American College of Surgeons National Surgical Quality Improvement Program database to determine the frequency and timing of onset of 30-d postoperative complications after APR and identify differences between open and laparoscopic APR. RESULTS: A total of 7681 patients undergoing laparoscopic or open APR between 2011 and 2015 were identified. The total complication rate for APR was high (45.4%). APRs were commonly complicated by blood transfusion (20.1%), surgical site infection (19.3%), and readmission (12.3%). Laparoscopic APR was associated with a 14% lower total complication rate compared to open APR (36.0% versus 50.1%, P < 0.001). This was primarily driven by a decreased rate of transfusion (10.7% versus 24.9%, P < 0.001) and surgical site infection (15.5% versus 21.2%, P < 0.001). Laparoscopic APR had shorter length of stay and decreased reoperation rate but similar rates of readmission and death. Cardiopulmonary complications occurred earlier in the postoperative period after APR, whereas infectious complications occurred later. CONCLUSIONS: Short-term complications following APR are common and occur more frequently in patients who undergo open APR. This, along with factors such as risk of positive pathologic margins, surgeon skill set, and patient characteristics, should contribute to the decision-making process when planning rectal cancer surgery.

RESUMEN

BACKGROUND AND OBJECTIVES: Sentinel lymph node (SLN) biopsy has become the standard method of determining regional lymph node involvement in cutaneous melanoma. Although traditionally performed via injection of radioisotope tracers and blue dyes, fluorescent lymphangiography with indocyanine green (ICG) is an attractive alternative. METHODS: Fifty two consecutive patients with cutaneous melanoma of the trunk or extremities underwent SLNB. Preoperative lymphoscintigraphy was performed with technetium-99m sulfur colloid (TSC). Peritumoral intradermal injection of isosulfan blue (ISB) and ICG was then performed. Successful identification of a sentinel lymph node via each modality was then assessed. RESULTS: A total of 77 lymph nodes were identified from the 52 patients (range 1-3). The majority of melanomas were extremity-based, superficial spreading type, and had SLN localized to the axilla. There were no complications related to IcG administration. Rates of SLN detection were 96.2% for TSC, 59.6% for ISB, and 88.5% for IcG (P < 0.05 for ICG vs ISB). On univariate logistic regression analysis, no factors were found to be associated with failure of ICG. CONCLUSIONS: Fluorescent lymphangiography using ICG is an effective method of SLN identification in patients with cutaneous melanoma of the trunk and extremities. When ICG and TSC are used in combination, ISB offers no additional advantage and may be safely omitted.

RESUMEN

Nonunions of the proximal pole of the scaphoid are a challenge to treat given the limited vascular supply. This challenge is potentiated when the proximal pole is unsalvageable. When the proximal pole of the scaphoid is fragmented or otherwise unsalvageable, traditional reconstructive procedures such as vascularized or nonvascularized bone grafting are not possible. Salvage procedures such as proximal row carpectomy or scaphoid excision and partial wrist fusion would not be ideal in the case of an unsalvageable proximal pole scaphoid nonunion in the absence of radiocarpal arthrosis. In this relatively uncommon circumstance, we favor the use of rib osteochondral autograft reconstruction of the proximal pole of the scaphoid. We report 3 cases with greater than 2-years of follow-up evaluation and also review the literature.
