Isolated external iliac lymph node recurrence is rare in rectal carcinoma. Herein we present a 78-year-old male with synchronous external iliac lymp node metastasis invading the external iliac artery and its successul surgical resection

The role of laparoscopic staging for the management of gastric cancer

AİM Staging laparoscopy enables us to perform palliative treatment, neo-adjuvant therapy for curative resection or direct curative resection and making a decision with minimal morbidity by avoiding from unnecessary laparotomies. In the present study, the importance of staging lapafoscopy was retrospectively investigated by using clinical and pathologic data. METHODS Data of 70 out of 350 patients who underwent diagnostic laparoscopy due to gastric cancer at Surgical Oncology department between August 2013 and January 2020 were retrospectively analyzed. RESULTS Peritoneal biopsy was positive for malignity in 41 (58.5%) and negative in 29 (41.5%) of the patients who underwent SL. Peritoneal cytology (PC) results were negative in 32 (45.7%) patients and positive in 38 (54.3%) patients. Peritoneal biopsy and cytology results were concurrently positive in 35 patients and concurrently negative in 26 patients. CONCLUSİONS In conclusion, even the most developed imaging methods cannot provide 100% staging, therefore SL plays an important role in treatment of gastric cancer and laparoscopic staging is essential as a simple, inexpensive, safe and well tolerated method in patients who have the suspicion of peritoneal disease and who cannot be clearly evaluated with pre-operative methods

Znaczenie laparoskopowej oceny zaawansowania w leczeniu raka żołądka

Cel: Laparoskopia z oceną zaawansowania (ang. staging laparoscopy; SL) pozwala na wdrożenie leczenia paliatywnego, terapii neoadjuwantowej przed leczeniem operacyjnym lub na bezpośrednią resekcję radykalną oraz na ustalenie strategii postępowania, co pozwala ograniczyć śmiertelność poprzez uniknięcie niepotrzebnych laparotomii. W naszym badaniu retrospektywnie oceniliśmy znaczenie laparoskopii z oceną zaawansowania w oparciu o dane kliniczne i histopatologiczne. Metody : Analizie retrospektywnej poddano dane 70 z 350 pacjentów poddawanych diagnostycznej laparoskopii z powodu raka żołądka w Klinice Chirurgii Onkologicznej od sierpnia 2013 do stycznia 2020 roku. Wyniki: Biopsja otrzewnej była dodatnia na obecność komórek nowotworowych u 41 (58,5%) pacjentów i ujemna u 29 (41,5%) pacjentów poddawanych SL. Cytologia płynu z otrzewnej była ujemna u 32 (45,7%) pacjentów i dodatnia u 38 (54,3%) pacjentów. Wyniki biopsji i cytologii były równocześnie dodatnie u 35 pacjentów i jednocześnie ujemne u 26 pacjentów. Wnioski: Podsumowując, nawet najbardziej zaawansowane metody obrazowania nie pozawalają w 100% ocenić zaawansowania procesu nowotworowego, tym samym SL odgrywa istotną rolę w leczeniu pacjentów z rakiem żołądka. Laparoskopowa ocena zaawansowania, jako zabieg prosty, tani, bezpieczny i dobrze tolerowany, powinna stanowić podstawę postępowania u pacjentów z podejrzeniem zajęcia otrzewnej, u których nie udaje się w pełni ocenić zaawansowania choroby badaniami przedoperacyjnymi

Stoma-free Survival After Rectal Cancer Resection With Anastomotic Leakage: Development and Validation of a Prediction Model in a Large International Cohort.

Objective:To develop and validate a prediction model (STOMA score) for 1-year stoma-free survival in patients with rectal cancer (RC) with anastomotic leakage (AL).Background:AL after RC resection often results in a permanent stoma.Methods:This international retrospective cohort study (TENTACLE-Rectum) encompassed 216 participating centres and included patients who developed AL after RC surgery between 2014 and 2018. Clinically relevant predictors for 1-year stoma-free survival were included in uni and multivariable logistic regression models. The STOMA score was developed and internally validated in a cohort of patients operated between 2014 and 2017, with subsequent temporal validation in a 2018 cohort. The discriminative power and calibration of the models' performance were evaluated.Results:This study included 2499 patients with AL, 1954 in the development cohort and 545 in the validation cohort. Baseline characteristics were comparable. One-year stoma-free survival was 45.0% in the development cohort and 43.7% in the validation cohort. The following predictors were included in the STOMA score: sex, age, American Society of Anestesiologist classification, body mass index, clinical M-disease, neoadjuvant therapy, abdominal and transanal approach, primary defunctioning stoma, multivisceral resection, clinical setting in which AL was diagnosed, postoperative day of AL diagnosis, abdominal contamination, anastomotic defect circumference, bowel wall ischemia, anastomotic fistula, retraction, and reactivation leakage. The STOMA score showed good discrimination and calibration (c-index: 0.71, 95% CI: 0.66-0.76).Conclusions:The STOMA score consists of 18 clinically relevant factors and estimates the individual risk for 1-year stoma-free survival in patients with AL after RC surgery, which may improve patient counseling and give guidance when analyzing the efficacy of different treatment strategies in future studies
