Comparative Study
Impact of flap reconstruction on perineal wound complications following ablative surgery for advanced and recurrent rectal cancers.
To determine the effect of flap reconstruction on perineal complications in locally advanced rectal cancers (LARC) and locally recurrent rectal cancers (LRRC). Prior studies have suggested that flap reconstruction may decrease wound complications after ablative surgery for rectal cancer but are limited by small sample sizes, heterogeneity of pathologies, and lack of comparison groups. ⋯ This study suggests that flap reconstruction may provide some protective effect against perineal complications in patients undergoing pelvic exenteration, although this was not observed for APR. The most important determinants of perineal complications after pelvic exenteration were operative time and sacral resection, but no predictive factors for post-APR perineal outcomes were identified.

There is substantial variation in the surgical complexity of hepatectomy. Currently, the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) risk adjusts for hospital quality comparisons using only the primary procedure code. Our objectives were to (1) assess the association between secondary procedures and complications; (2) assess model performance with inclusion of surgical complexity adjustment; and (3) examine whether secondary procedures affect hospital quality rankings. ⋯ Secondary procedures are associated with an increased risk of postoperative complications. Inclusion of secondary procedure code categories in research and risk prediction models should be considered for hepatectomy.

Pancreaticoduodenectomy is the standard of care for tumors confined to the head of pancreas and can be undertaken with low operative mortality. The procedure has a high morbidity, particularly in older patient populations with preexisting comorbidities. This study evaluated the role of cardiopulmonary exercise testing to predict postoperative morbidity and outcome in high-risk patients undergoing pancreaticoduodenectomy. ⋯ CPET is a useful adjunctive test for predicting postoperative outcome in patients being assessed for pancreaticoduodenectomy. Raised CPET-derived [Formula: see text] E/[Formula: see text] CO 2 predicts early postoperative death and poor long-term survival.

The debate remains whether appendiceal goblet cell cancers behave as classical carcinoid or adenocarcinoma. Treatment options are unclear and reports of outcomes are scarce. Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS+HIPEC) is considered optimal treatment for peritoneal involvement of other epithelial appendiceal tumors. ⋯ This data supports the concept that appendiceal goblet cell cancers behave more as high-grade adenocarcinomas than as low-grade lesions. These patients have reasonable long-term survival when treated using CRS+HIPEC, and this strategy should be considered.

En bloc resection of the superior mesenteric vein (SMV), portal vein (PV), and/or splenic vein (SV) with concomitant venous reconstruction is required in 11-65 % of cases of locally advanced pancreatic cancer.1 Early retropancreatic dissection of the superior mesenteric artery (SMA) from behind the pancreatic head utilizing an 'artery first' approach has been reported to be an efficient and safe approach to pancreaticoduodenectomy when SMA involvement is suspected.2 Additionally, this technique has been shown to reduce blood loss and result in shorter PV clamp times.3 While there are multiple variations to 'artery first' resection,4 this video will illustrate the critical steps of using the 'posterior approach' in patients with locally advanced pancreatic cancer. This approach has the benefit of early identification of a replaced right hepatic artery, but may be difficult in obese patients or those with extensive peripancreatic inflammation. These difficulties may be overcome by utilizing an 'inferior supracolic (anterior) approach', but this necessitates early division of the pancreatic neck and stomach.5 METHODS: Select video clips were compiled from several pancreatoduodenectomies to demonstrate this technique. A variety of bipolar devices were utilized for dissection depending on surgeon preference. All patients were diagnosed with locally advanced pancreatic cancer by Americas Hepato-Pancreato-Biliary Association/Society of Surgical Oncology (AHPBA/SSO) consensus criteria, confirmed by biopsy, and completed neoadjuvant chemotherapy. Patients were restaged by pancreas protocol computed tomography scan at the end of chemotherapy and offered local resection if the tumor did not progress and they were medically fit. No Institutional Review Board approval was required. ⋯ The 'artery first' approach has been shown to be safe and feasible in pancreatic resections. This technique should be considered whenever tumor is thought to involve the SMV and/or PVs as a means to facilitate safe venous resection and reconstruction while preserving sound oncologic principles.
