Segmental resection of splenic flexure colon cancers provides an adequate lymph node harvest and is a safe operative approach – an analysis of the ACS-NSQIP database

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.

Surgical Techniques and Outcomes of Colorectal Anastomosis after Left Hemicolectomy with Low Anterior Rectal Resection for Advanced Ovarian Cancer

Extended colon resection is often performed in advanced ovarian cancer. Restoring intestinal continuity and avoiding stoma creation improve patients’ quality of life postoperatively. We tried to minimize the number of anastomoses, restore intestinal continuity, and avoid stoma creation for 295 patients with stage III/IV ovarian cancer who underwent low anterior rectal resection (LAR) with or without colon resection during cytoreductive surgery. When the remaining colon could not reach the rectal stump after left hemicolectomy with LAR, we used the following techniques for tension-free anastomosis: right colonic transposition, retro-ileal anastomosis through an ileal mesenteric defect, or an additional colic artery division. Rates of stoma creation and rectal anastomotic were 3% (9/295) and 6.6% (19/286), respectively. Among 21 patients in whom the remaining colon did not reach the rectal stump after left hemicolectomy with LAR, 20 underwent tension-free anastomosis, including eight, six, and six patients undergoing right colonic transposition, retro-ileal anastomosis through an ileal mesenteric defect, and an additional colic artery division, respectively. Colorectal anastomosis is feasible for patients with extended colonic resection. Low anastomotic leakage and stoma rates can be achieved with careful attention to colonic mobilization and tension-free anastomosis.

Long splenic flexure carcinoma requiring laparoscopic extended left hemicolectomy with CME and transverse-rectal anastomosis: technique for a modified partial Deloyers in 5 steps to achieve enough reach and preserving middle colic vessels

Introduction This How-I-Do-It article presents a modified Deloyers procedure by mean of the case of a 67-year-old female with adenocarcinoma extending for a long segment and involving the splenic flexure and proximal descending colon who underwent a laparoscopic left extended hemicolectomy (LELC) with derotation of the right colon and primary colorectal anastomosis. Background While laparoscopic extended right colectomy is a well-established procedure, LELC is rarely used (mainly for distal transverse or proximal descending colon carcinomas extending to the area of the splenic flexure). LELC presents several technical challenges which are demonstrated in this How-I-Do-It article. Technique and methods Firstly, the steps needed to mobilize the left colon and procure a safe approach to the splenic flexure are described, especially when a tumor is closely related to it. This is achieved by mobilization and resection of the descending colon, while maintaining a complete mesocolic excision to the level of the duodenojejunal ligament for the inferior mesenteric vein and flush to the aorta for the inferior mesenteric artery. Subsequently, we depict the adjuvant steps required to enable a primary anastomosis by trying to mobilize the transverse colon and release as much of the mesocolic attachments at the splenic flexure area. Finally, we present the rare instance when a laparoscopic derotation of the ascending colon is required to provide a tension-free anastomosis. The resection is completed by delivery of the fully derotated ascending colon and hepatic flexure through a suprapubic mini-Pfannenstiel incision. The primary colorectal anastomosis is subsequently fashioned in a tension-free way and provides for a quick postoperative recovery of the patient. Results This modified Deloyers procedure preserves the middle colic since the fully mobilized mesocolon allows for a tension-free anastomosis while maintaining better blood supply to the mobilized stump. Also, by eliminating the need for a mesenteric window and the transposition of the caecum, we allow the small bowel to rest over the anastomosis and the mobilized transverse colon and reduce the possibility of an internal herniation of the small bowel into the mesentery. Conclusions Laparoscopic derotation of the right colon and a partial, modified Deloyers procedure preserving the middle colic vessels are feasible techniques in experienced hands to provide primary anastomosis after LELC with improved functional outcome. Nevertheless, it is important to consider anatomical aspects of the left hemicolectomy along with oncological considerations, to provide both a safe oncological resection along with good postoperative bowel function.

A Comparative Study of Colorectal Cancer Based on Patient’s Age

Background: The alteration of bowel habits, bleeding per-rectum and anemia were common features in both groups in this study, but in young patients there was a delay of 6 months between the presenting symptoms and the definitive diagnosis because the disease was not suspected and investigated in them. The most common site for the tumors in young patients was the rectum and in patients above the age of 40 years was the Sigmoid. The pathological finding showed that classification of the colorectal tumors in young patients appear moderately to poorly differentiated adenocarcinoma , this indicate a more malignant course of the disease in young patients. This study send a message to all clinicians that the incidence of colorectal cancer is increasing in young patients and therefore we should be alert when dealing with young patients presenting with abdominal pain, bleeding per-rectum and alteration of bowel habit to diagnose the disease at an early stage to undertake curative surgery . Aim of the study: To study the clinical coarse of colorectal cancer in age between (less than 40 to above 40), and the most frequent site and distribution, and the types of surgical intervention. Patients and methods: In the period between January 2012 to March 2013, 35 patients with colorectal cancer were treated at Al-Yarmouk Hospital,10 patients were below the age of 40 years ,( 5 Males and 5 Females ) with age ranging from 22-40 years , 25 patients were above the age of 40 years (12 males and13 females). Results:100% of patients less than 40 years presenting as anemia and 50% bleeding per rectum, while 88% of patients above 40 years with weakness and lethargy.30% of patients less 40years age, and 36% of patients above 40 years consider as an emergency cases, and others as elective cases. Surgical treatment involving 50% of patients less than 40 are right, left hemicolectomy and anterior resection, and in age of above 40 56% by left hemicolectomy. More common stages in young patents are C and B but in old A ,B , C. Recommendations: Researchers recommend periodic screening by a doctor to diagnose the tumor early with the need to develop educational programs on early signs of colorectal cancer.

Left Hemicolectomy for Intussusception of the Transverse Colon Caused by a Giant Benign Lipoma

Colocolonic intussusception, caused by submucosal lipomas, is extremely rare. These benign soft tissue tumours comprise mature adipocytes of mesenchymal origin. While the majority of patients with lipomas remain asymptomatic, large or giant size lipomas (>4 cm) have been shown to cause debilitating abdominal pain, alternating bowel pattern, and anaemia secondary to gastrointestinal blood loss. This necessitates intervention in the form of surgical resection or endoscopic removal. However, once lipomas increase beyond 2 cm in size there is a significant risk of complications with an endoscopic approach, and open surgery or laparoscopic resection with bowel re-anastomosis is warranted. In this case put forth, the patient underwent a successful transverse colectomy and primary anastomosis.

Peculiarities of the postoperative period and postoperative consequences of left hemicolectomy in patients with obesity

Annotation. Obesity is considered a risk factor for postoperative complications and postoperative mortality. The aim of the study was to assess the impact of obesity on the postoperative period and the level of postoperative mortality after left hemicolectomy. A retrospective analysis of the medical records of 217 patients who underwent left hemicolectomy for colon tumors was performed. Assessment of comorbid conditions was performed using the Charlson index. Postoperative complications were assessed according to the Clavien-Dindo classification. The calculation of postoperative survival was performed by the Kaplan-Mayer method. Database formation and statistical analysis were performed using Microsoft Excel and STATISTICA 10.0. It was determined that the mean values of the Charlson index did not differ significantly between the two groups (6,31 ± 2,07 and 6,33 ± 2,08 respectively), but there was a significantly higher level of endocrine diseases in the group of obese patients. Non-disseminated (I-II) stages of the tumor process predominated in patients of both groups (60% and 57.5%, respectively). Among non-obese patients n = 107 (51.8%) patients had an uncomplicated postoperative period and n = 59 (28.5%) patients had mild complications that were not associated with the surgical site, but were associated with concomitant chronic pathology of other organs and systems, and did not require any invasive interventions. In contrast, among obese patients n = 6 (60%) patients had severe early postoperative complications requiring surgery, and n = 2 (20%) patients underwent relaparotomy. The rate of early postoperative mortality differed significantly between the two groups and was significantly higher among obese patients (40% vs 6.8% among non-obese patients). This study showed a significantly higher percentage of postoperative mortality and severity of postoperative complications in the group of obese patients. The prospect of further research is to study and analyze the course of the postoperative period in obese patients undergoing extended, multi-visceral and multi-stage surgery for cancer of the left half of the colon.
