Abstract
Introduction Fewer than 10% of colon cancers are found at the splenic flexure. A standard surgical approach to these cancers has not been defined. The goal of this study was to compare lymph node harvest and post-operative morbidity between segmental resection and formal left hemicolectomy for splenic flexure colon cancers. Method Patients diagnosed with a splenic flexure cancer were identified from the 2012–2018 ACS-NSQIP colectomy-targeted database. Patients were categorized based on type of surgical resection – left hemicolectomy with colorectal anastomosis or segmental colectomy with colocolonic anastomosis. Demographic, clinicopathologic, and post-operative outcomes were compared between groups. Factors independently associated with lymph node harvest, operative time, and post-operative morbidity were investigated by linear and binomial logistic regression models. Results A total of 3,049 patients underwent colectomy for a splenic flexure cancer. Of these, 83.6% had a segmental colectomy and 73% were performed by a minimally invasive approach. T- and N-stage did not differ between segmental and left hemicolectomy groups (p = 0.703 and p = 0.429, respectively). Inadequate nodal harvest (< 12 nodes) was infrequent and similar between the two procedures (7.4% vs. 9.1%, p = 0.13). Operative time was significantly shorter for segmental colectomy (213 ± 83.5 min vs. 193 ± 84.1 min, p < 0.0001) and major morbidity was similar between the two surgical techniques (8.4% vs. 8.9%, p = 0.75). After accounting for demographic, clinicopathologic, and operative factors, binomial logistic regression showed that type of procedure was not significantly associated with LN harvest (OR 0.80, 95%CI 0.54–1.17) or major morbidity (OR 1.17, 95%CI 0.36–3.81). However, on linear regression, segmental splenic flexure resection was associated with shorter operative time (estimate 20.29, 95%CI 12.61–27.97, p < 0.0001). Conclusion Splenic flexure resection for colon cancer is associated with an adequate lymph node harvest. Compared to a formal left hemicolectomy, a segmental resection also has a shorter operative time with equivalent post-operative morbidity.

Abstract
Management of malignant left-sided colonic obstruction remains challenging and requires a stoma in 40-65% of patients. In those with obstructive splenic flexure colon cancer (OSFCC), a debate still exists regarding the most appropriate surgery. The aim of this muticenter study was to report and compare the different surgical procedures in OSFCC patients with a special focus on operative and histological characteristics and survival outcomes including 12-month stoma-free survival. Between 2000 and 2015, 2325 patients were treated for obstructive colon cancer in centers members of the French National Surgical Association (AFC). Among them, 198 underwent surgery for OSFCC and were retrospectively analyzed. Patients with OSFCC and proximal colonic ischemia or perforation were excluded. Four procedures were performed: decompressing stoma (DS, 39%), splenic flexure colectomy (SFC, 39%), subtotal colectomy (STC, 17%,) and left hemicolectomy (LHC, 5%). All patients treated with LHC underwent a Hartmann's procedure. There was no significant difference between groups for postoperative mortality and morbidity. Hospital stay was significantly longer after DS. The length of the specimen, longitudinal resection margins and number of harvested lymph nodes were significantly higher in the STC group. There was no difference for overall and disease-free survival. Stoma-free survival was significantly lower after LHC (62%) in comparison with the other groups (p < 0.0001). At the end of follow-up, 50% of patients who underwent LHC had a permanent stoma. In OSFCC patients without proximal colonic ischemia or peritonitis, LHC should no longer be recommended due to a high risk of permanent stoma.

Abstract
Laparoscopic approaches have become a standard strategy for colon cancer patients who undergo surgical treatment. Complete mesocolic excision (CME) with central vascular ligation (CVL) is the fundamental principle of radical resection of colon cancers. Splenic flexure colon cancer (SFCC) is rare, accounting for less than 4% of all colorectal cancer cases. Moreover, a laparoscopic approach for SFCC following the CME/CVL concept can be challenging because the blood supply of the splenic flexure is derived from either the middle colic artery (MCA) branching from the superior mesenteric artery, the left colic artery (LCA) branching from the inferior mesenteric artery. In addition, approximately one third of SFCC patients have an accessory MCA that can originate from the celiac trunk. Herein, we describe the technical procedure of a laparoscopic left hemicolectomy for SFCC using indocyanine green (ICG) for necessary and sufficient lymphadenectomy followed by intracorporeal anastomosis. Two injections of ICG (0.5 mg/0.2 ml × 2) into the subserosa of the proximal and distal sides of the tumor preceded the surgical procedure after pneumoperitoneum. Near infrared images obtained throughout the laparoscopic procedure helped visualize lymphatic drainage vessels and inform decision making for determining vessels requiring ligation according to the CVL concept: MCA, LCA or accessory MCA. Complete intracorporeal anastomosis following necessary and sufficient lymphadenectomy with ICG can minimize the dissecting area of the laparoscopic left hemicolectomy for SFCC patients. Intravenous ICG injection (2.5 mg) after anastomosis helps confirm blood perfusion at the anastomosis site. Four patients with SFCC underwent a laparoscopic colectomy under ICG navigation in 2019 at our institute. The median operative time was 237 min, the median estimated blood loss was 0 ml, and the median number of dissected lymph nodes was 13. No patients experienced postoperative complications. In conclusion, laparoscopic left hemicolectomy with ICG navigation and intracorporeal anastomosis for SFCC patients may be a feasible option for the radical resection of colon cancer.

Abstract
BACKGROUND What qualifies as optimal lymph node (LN) dissection in the surgical management of splenic flexure colon cancer (SFCC) still remains controversial because few studies have evaluated the distribution of LN metastasis of SFCC. The aim of this study was to clarify detailed distribution of LN metastasis and long-term outcomes of SFCC. METHODS This retrospective study enrolled patients who had curative colectomy for primary transverse or descending colon cancer of pathological stage I, II, or III at a single high-volume cancer center between April 2002 and December 2018. The 538 eligible patients were divided into three groups: patients with SFCC (SFCC group, n = 168), patients with proximal transverse colon cancer (PTCC group, n = 290), and patients with distal descending colon cancer (DDCC group, n = 80). LNs were classified into horizontal (pericolic) and vertical (intermediate and main) nodes. Intermediate and main LN station numbers were defined according to the Japanese Society for Cancer of the Colon and Rectum classification. Distributions of LN metastasis and long-term outcomes were compared. RESULTS In the SFCC group, the mean age was 67.3 ± 10.5 years and 110 patients (65.5%) were male. The proportion of patients with LN metastasis in the intermediate or main region was significantly lower in the SFCC group (8%) than in the PTCC (37%) (p < 0.01) or DDCC group (29%) (p < 0.01) in pathological stage III patients. In the SFCC group, the incidence of pericolic LN metastasis on the oral side of tumor (43%) was significantly higher than in the PTCC group (21%) (p < 0.01) and was similar to that in the DDCC group (42%) (p = 0.51), while in the SFCC group, the incidence of pericolic LN metastasis on the anal side of tumor (17%) was lower than in the PTCC group (31%) and was also similar to that in the DDCC group (21%). There were no significant differences in disease-specific survival rates among all groups. CONCLUSIONS LN metastasis occurred mainly in the pericolic region, especially on the oral side of the tumor in SFCC. It may, therefore, be important to have an adequate bowel resection margin, especially on the oral side, for SFCC.

Abstract
BACKGROUND There is ongoing debate regarding surgical treatment of splenic flexure cancer. The main points of controversy include the appropriate extent of colon resection, either to the right or to the left, and the appropriate extent of lymph-node dissection. The aim of this study was to review our experience in laparoscopic treatment of splenic flexure cancer cases and to compare our data to the recent literature. METHODS Consecutive patients, operated on for splenic flexure colon carcinoma at a single institution between April 2005 and January 2013, were included in the study. Exclusion criteria were a previous history of colorectal cancer, recurrent colonic cancer, emergency cases with an obstructive tumor or a perforated tumor with peritonitis, synchronous cancer, palliative surgery, and a past history of colorectal resection. Patients underwent laparoscopic segmental left colectomy with ligation of the left branch of the middle colic and of the left colic artery. Patient characteristics, operative and postoperative outcomes, and long-term technical, functional, and oncological results from a prospectively maintained database were retrospectively analyzed. After hospital discharge, standardized follow-up was performed at 1 month postoperatively, then every 3 months during the first 2 years, and every 6 months thereafter, for a total of 5 years. RESULTS A total of 28 consecutive patients (16 males) with a median age of 71.8 years (range 42.5-88.8 years) were included. Ninety-day mortality was 3.5% and surgical morbidity was 21.5% with anastomotic leak rate of 10.7%. All survivors experienced good or very good functional results. During a median follow-up period of 50.9 months, eight patients (28.5%) presented with a recurrence. The 5-year overall and disease-free survival rates were 46.3% and 39.2%, respectively. CONCLUSIONS Segmental left colectomy for splenic flexure carcinoma is associated with reasonably low morbidity and very good functional results. However, survival rates are low.
