Herein the author includes his philosophical take on how surgeons’ deal with complications. He explains how often Mortality and Morbidity meetings miss a fundamental point of how the surgeon him/herself deals with complications. The author proposes a classification of the 4 commonest coping strategies used by mankind to deal with the doubt and uncertainty that a career in surgery, a real marathon, entails. This is explored in an honest, easy to read and amusing way with some real truths within. © 2017

Pseudomyxoma peritonei (PMP) is a complex disease with unique biological behavior that usually arises from appendiceal mucinous neoplasia. The classification of PMP and its primary appendiceal neoplasia is contentious, and an international modified Delphi consensus process was instigated to address terminology and definitions. A classification of mucinous appendiceal neoplasia was developed, and it was agreed that "mucinous adenocarcinoma" should be reserved for lesions with infiltrative invasion. The term "low-grade appendiceal mucinous neoplasm" was supported and it was agreed that "cystadenoma" should no longer be recommended. A new term of "high-grade appendiceal mucinous neoplasm" was proposed for lesions without infiltrative invasion but with high-grade cytologic atypia. Serrated polyp with or without dysplasia was preferred for tumors with serrated features confined to the mucosa with an intact muscularis mucosae. Consensus was achieved on the pathologic classification of PMP, defined as the intraperitoneal accumulation of mucus due to mucinous neoplasia characterized by the redistribution phenomenon. Three categories of PMP were agreed - low grade, high grade, and high grade with signet ring cells. Acellular mucin should be classified separately. It was agreed that low-grade and high-grade mucinous carcinoma peritonei should be considered synonymous with disseminated peritoneal adenomucinosis and peritoneal mucinous carcinomatosis, respectively. A checklist for the pathologic reporting of PMP and appendiceal mucinous neoplasms was also developed. By adopting the classifications and definitions that were agreed, different centers will be able to use uniform terminology that will allow meaningful comparison of their results. © 2015 Wolters Kluwer Health, Inc.

BACKGROUND: Pseudomyxoma peritonei is a diffuse peritoneal malignancy that generally originates form a perforated appendiceal tumor. Optimal treatment requires extensive surgical resection to achieve complete cytoreduction combined with hyperthermic intraperitoneal chemotherapy. In a proportion of patients this is impossible, in particular, owing to extensive irresectable small-bowel involvement. There is ongoing debate as to the role of maximal tumor debulking in such cases. OBJECTIVE: The aim of this study was to assess the outcomes of patients who underwent major tumor debulking for pseudomyxoma peritonei of appendiceal origin and to compare outcomes with patients who had complete cytoreduction during the same period. DESIGN: This is a retrospective study. SETTINGS: This investigation was conducted at a tertiary referral center for peritoneal surface malignancy. PATIENTS: A prospective database of 953 consecutive patients with peritoneal malignancy undergoing surgery at a UK national referral center between 1994 and 2012 was analyzed. Of these patients, 748 (78%) had surgery for pseudomyxoma peritonei of appendiceal origin. MAIN OUTCOME MEASURES: Survival, morbidity, and mortality in both groups were compared. Univariate and multivariate analyses were performed to identify negative prognostic factors in the group that underwent major tumor debulking. RESULTS: Complete cytoreductive surgery was achieved in 543/748 (73%) patients, and 205 (27%) had maximal tumor debulking. Median age was 56 years (172 (31.7%) men) in the complete cytoreductive surgery group and 59 years (108 (52.7%) men) in the maximal tumor debulking group. Overall survival at 3, 5, and 10 years was 90%, 82%, and 64% in the complete cytoreductive group and 47%, 30%, and 22% in the maximal tumor debulking group. The median survival in the maximal tumor debulking group was 32.8 months (95% CI, 24.1-41.5). LIMITATIONS: The retrospective analysis of prospective data was a limitation of this study. CONCLUSIONS: Maximal tumor debulking may help patients with pseudomyxoma peritonei in whom complete cytoreduction cannot be achieved with almost half alive at 3 years with long-term survival in some. © The ASCRS 2013.
