Comparative Study
Long-term clinical and functional results of intersphincteric resection for lower rectal cancer.
Intersphincteric resection (ISR) is an alternative to abdominoperineal resection (APR) for super-low rectal cancer. The aim of this study was to evaluate the long-term curability after ISR over an average 6-year observational period, to compare the postoperative functional outcomes for ISR with those for low anterior resection (LAR), and to determine whether ISR is a function-preserving surgery. ⋯ The long-term clinical and functional results suggest that ISR may be the optimal sphincter-preserving surgery for patients with lower rectal cancers who cannot be treated with a double-stapling technique.

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.
