What is the effect of percutaneous cholesistostomy in patients with acute cholecystitis? when is the right time for the procedure?

BACKGROUND: Acute cholecystitis (AC) is one of the most common emergency diseases in surgical practice. Although the gold standard treatment is laparoscopic cholecystectomy, percutaneous cholecystostomy (PC) is performed in some patients due to age, comorbidity, and delays in admission. We aimed to investigate the effect of timing on the clinical process of patients undergoing PC. METHODS: Patients who underwent PC between February 2017 and December 2021 were included in the study. Those who un-derwent PC in the first 72 h were determined as the early PC group, and those who underwent PC after 72 h were determined as the late PC group. Demographic information of the patients, clinical information before drainage, biochemical values of the first 3 days, length of hospital stay, morbidity and mortality in the early and late period after drainage, and elective cholecystectomy information were recorded. These data were compared between the two groups. RESULTS: One hundred and twenty-two patients were included in the study. Early PC was performed in 98 patients (80.3%) and late PC was performed in 24 patients (19.7%). The median follow-up period was 26.6 months (min: 0.25-max: 67) in the early PC group and 26.4 months (min: 0.6-max: 66) in the late PC group (P=0.408). There was no statistically significant difference in mean age, distribu-tion of males and women, concomitant disease, Charlson Comorbidity Index, hepatopancreatobiliary pathology (HPBP), endoscopic retrograde cholangiopancreatography in history and grade (TG18) compared to Tokyo classification (P>0.05). There was no difference between the biochemical parameters (P>0.05). In our study, the median length of hospital stay was 6 (min: 2-max: 36) days in the early PC group, and the median was 9 days (min: 5-max: 20) in the late PC group (P<0.001). A total of 25 patients developed HPBP after PC, 16 of which were AC. There was no statistically significant difference between the early and late PC groups in terms of HPBP develop-ment after PC (P=0.576). There was no statistically significant difference between the early and late PC group in terms of the rate of surgery and type of operation (emergency/elective, open/laparoscopic/conversion, total/subtotal, duration) (P>0.05). CONCLUSION: Discussions about the right timing are ongoing. In our study, we found that patients who underwent early PC had shorter hospital stays. There was no difference between the early and late groups in terms of patient characteristics and severity of AC. PC procedure in AC should be based on algorithms determined by objective data instead of patient-based indications with ran-domized controlled trials.

Impact of positive-to-total lymph node ratio on prognosis in stage 3 colorectal cancer. A multicenter study.

BACKGROUND: Colorectal cancer remains a health problem despite advances in diagnostic and treatment methods. This study aimed to determine the impact of positive-to-total lymph node ratio on survival in colorectal cancer. METHODS: Patients with stage 3 colorectal cancer were included. Patients age; sex; operation type (emergency or elective); tumor size, grade, and location; TNM stage; vascular and perineural invasions; numbers of lymph nodes examined and negative lymph nodes, positive-to-total lymph node ratio, and administration of postoperative chemotherapy were examined. RESULTS: Median follow-up period was 34.7 months. Most patients were in stage 3b (67.9%), and the median number of dissected lymph nodes was 15. The number of metastatic lymph nodes, positive lymph node ratio, and negativeto- positive lymph node ratio were 3, 16.7, 11, and 5, respectively. The overall survival rate was 48.6%. Mean life expectancy was 51.5 months. Multivariate Cox regression analysis revealed positive-to-total lymph node ratio >23.3%, age, and absence of postoperative chemotherapy as risk factors for overall survival (p<0.05). Positive-to-total lymph node ratio >23.3% was associated with poor overall survival and 3.726-fold poorer survival. DISCUSSION: Positive-to-total lymph node ratio >23.3% is a risk factor affecting overall survival in stage 3 colorectal cancer. Increased positive-to-total lymph node ratio (>23.3%) is associated with poor overall survival. KEY WORDS: Colorectal Cancer, Overall Survival, Positive Lymph Node Ratio, Stage 3 Cancer.

Analysis of factors related to the decision of Hartmann's procedure and its reversal: a single-center experience.

BACKGROUND: Hartmann's procedure (HP) is commonly applied to resolve acute clinical conditions in most cases with colonic obstruction or perforation. HP and the closure of the end colostomy are associated with high morbidity-mortality rates. In our study, we aimed to report our clinical experience in HP. METHODS: Demographic data and outcomes of Hartmann procedures performed between 2015 and 2023 were retrospectively reviewed. RESULTS: The median age of our study was 63 (18-94) years; 65 of the patients were female, and 97 were male. Colorectal malig-nancies were the primary etiology in 50% of patients who underwent HP, with 70% presenting with obstruction and 30% with perfora-tion. Two-thirds of the patients were American Society of Anesthesiologists-2 or higher. Postoperative complications did not develop in 74.7% of patients. Our mortality rate was 33.3%. The colostomy was closed in 59 patients during an average 2-year follow-up. The median closure time was 311 (57-1319) days. A stapler was used in 89.8% of patients during the closure. A diverting ileostomy was created in only two patients. The median hospital stay was 8 (5-70) days. Post-operative complications did not develop in 25.4% of patients, while four patients died. CONCLUSION: In our population, HP was more commonly performed for colorectal cancer. The procedure and closure of the ostomy result in low stoma closure rates, high morbidity, and mortality rates, as well as surgical difficulties.
