“…The early mobilization of the root of TMC from the pancreatic border allows for developing plenty of space around the vascular pedicles, which are dealt at the end. This strategy of creating wide space surrounding the pedicles has also been utilized by Koinuma et al who studied virtual surgical anatomy using preoperative 3D‐CT and familiarized the surgeons about the vascular variations 38 …”

[39][40][41] They underscore the feasibility of this new procedure and suggest that the robot may minimize the necessity of mobilizing both colonic flexures and facilitate intracorporeal hand-sewn anastomosis.…”

Surgical management of adenocarcinoma of the transverse colon: What should be the extent of resection?

Transverse colon, owing its origin to midgut and hindgut and harbouring a flexure at both ends, continues to pose a surgical challenge. When compared to the rest of the colon, transverse colon adenocarcinoma is relatively uncommon. These cancers usually present late and lie in close proximity to the stomach, omentum, and pancreas. Adequate lymphadenectomy entails dissection around and ligation of the middle colic vessels. Hence, resectional surgery for transverse colon carcinoma is considered difficult. This is more so because of the variation of arterial and venous anatomy. From this perspective, the surgeon is tempted to perform a more radical operation like extended right or left hemicolectomy to secure an adequate lymphadenectomy. Such a cancer has also been dealt with a more limited transverse colectomy with colo‐colic anastomosis. For all these reasons, patients with transverse colon adenocarcinoma were excluded from randomised trials which compared laparoscopic resection with traditional open operation. Surgical literature is yet to establish a definite operation for transverse colon cancer and the exact procedure is often dictated by surgeon's preference. This is primarily because this is an uncommon cancer. The rapid adoption of laparoscopic operation favoured extended colectomy as transverse colectomy can be difficult by minimally invasive technique. However, in the recent past, cohort studies and meta‐analyses have shown equivalent oncological outcome between transverse colectomy and extended colectomy. It is time to resurrect transverse colectomy and consider it equivalent to its radical counterpart for cancers around the mid‐transverse colon.

“…According to the International Agency for Research on Cancer (IARC), over 1.8 million new colorectal cancer cases and 881,000 deaths were estimated to occur in 2018, and colorectal cancer ranked third in terms of cancer incidence and second in terms of cancer mortality [ 1 ]. The surgical treatment for colorectal cancer has improved significantly with technical advances and theoretical progress [ 2 ], while the surgical procedures for transverse colon cancer can be controversial because of the location of the tumor [ 3 , 4 ]. For right-transverse colon cancer, the conventional surgical procedure is laparoscopic extended hemicolectomy with extracorporeal anastomosis.…”

Background: To evaluate the feasibility and safety of a new surgical method, complete laparoscopic extended right hemicolectomy with preservation of the ileocecal junction in right-transverse colon cancer. Methods: We retrospectively analyzed and compared the data of consecutive patients with right-transverse colon cancer who underwent complete laparoscopic extended right hemicolectomy with preservation of the ileocecal junction (n = 23) and conventional complete laparoscopic extended right hemicolectomy (n = 34) in our hospital between October 2017 to May 2019, respectively. Results: The overall operation time of the ileocecal junction-preserved group was significantly shorter than that of the control group (p = 0.048). There was no difference in the number of harvested lymph nodes, metastatic lymph nodes, and rate of metastatic lymph nodes (p > 0.05). The ileocecal junction-preserved group showed shorter time of first flatus, lower frequency of postoperative diarrhea, and shorter duration of postoperative hospitalization. Furthermore, it also showed that the defecation frequency was lower in the ileocecal junction-preserved group than the control group on the 1st, 3rd, and 6th month (p < 0.05), and the number of patients who defecated at night or defecated four times or more a day was less in the ileocecal junction-preserved group than control group on the 1st month (p < 0.05). Conclusion: The complete laparoscopic extended right hemicolectomy with preservation of the ileocecal junction promises as a safe and feasible surgical procedure for right-transverse colon cancer, associated with earlier recovery of bowel function, shorter operation time, and similar pathological outcomes when compared to the conventional laparoscopic procedure.
