Duodenal Invasion

Direct invasion of colorectal adenocarcinoma into adjacent structures occurs frequently, but only rarely is the duodenum involved. This study was undertaken to assess the safety and efficacy of en bloc resection of locally advanced right colon carcinoma invading the duodenum. A retrospective review of 49 patients with locally advanced colon cancer, surgically managed between 2000 and 2005, was performed. Forty-six patients underwent en bloc resection of colon and adjacent organs not involving the duodenum. Three patients with duodenal invasion underwent en bloc partial duodenectomy. The mean operative blood loss, length of stay, postoperative morbidity, and mortality compare favorably between these two groups of patients. Of the 46 patients with en bloc resection of other organs, 27 are alive at 12 to 60 months follow up. Two patients with duodenal invasion are alive without recurrence at 15 and 20 months follow up. En bloc resection of colon cancer invading the duodenum can be performed safely because morbidity and mortality rates are comparable to those attending extended resections of other locally advanced colon carcinomas. Overall survival in patients who underwent surgery with curative intent justifies en bloc duodenal resection in selected patients.

ABSTRACT Although colorectal tumors are fairly common surgical conditions, 5 to 12% of these tumors are locally advanced (T4 tumors) upon diagnosis. In this particular situation, the efficacy of en bloc multivisceral resection has been proven. When right-colon cancer invades the proximal duodenum or even the pancreatic head, a challenging dilemma arises due to complexity of the curative surgical procedure. Therefore, en bloc pancreaticoduodenectomy with right hemicolectomy should be performed to obtain free margins. The present study reports three cases of locally advanced right-colon cancer invading the proximal duodenum. All of these cases underwent successful en bloc pancreaticoduodenectomy plus right hemicolectomy, with no death occurrence. Long-term survival was observed in two cases (30 and 50 months). In the third case, the patient did not present any recurrence twelve months after surgical treatment. Multivisceral resection with en bloc pancreaticoduodenectomy should be considered for patients who present acceptable risk for major surgery and no distant dissemination. This approach seems justified since the length of postoperative survival is longer in radically ressected groups (R0) than in palliativelly resected groups (R1-2).

Duodenal Invasion

Right colon carcinoma with duodenal invasion is rare, and optimal management remains controversial. Twenty patients demonstrating right-colon carcinoma directly invading the duodenum presented at the Second Xiangya Hospital between 1990 and 2006. Different surgical management strategies were selected based on duodenal involvement, and patient outcomes were evaluated. There was no perioperative death in this series, but three major complications presented during the perioperative period: one case of duodenal stenosis and two duodenal leaks due to gastric or duodenal drainage. Eight of 13 patients treated by en bloc resection survived more than 3 years, including one 10-year survivor and four 5-year survivors. Of the seven patients treated with palliative resection, no patients survived more than 18 months. In conclusion, duodenal invasion by a right-sided colon carcinoma does not necessarily represent incurable disease. If carefully applied based on the extent of duodenal invasion, active surgical management is very useful for improving patient prognosis without increasing the risks associated with surgery.

This study aimed to assess the utility of the S-O clip during colorectal endoscopic submucosal dissection (ESD). We conducted a retrospective study on 185 patients who underwent colorectal ESD from January 2015 to January 2020. The patients were divided into two groups: before and after the introduction of the S-O clip. Forty-two patients underwent conventional ESD (CO group) and 29 patients underwent ESD using the S-O clip (SO group). We compared the surgery duration, dissection speed, en bloc resection rate, and complication rate between both groups. Compared with the CO group, the SO group had a significantly shorter surgery duration (70.7 ± 37.9 min vs. 51.2 ± 18.6 min; p = 0.017), a significantly higher dissection speed (15.1 ± 9.0 min vs. 26.3 ± 13.8 min; p < 0.001), a significantly higher en bloc resection rate (80.9% vs. 98.8%; p ≤ 0.001), and a significantly lower perforation rate (4.3% vs. 1.3%). In the right colon, the surgery duration was significantly shorter and the dissection speed was significantly higher in the SO group than in the CO group. Moreover, the rate of en bloc resection improved significantly in the right colon. S-O clip-assisted ESD reduces the procedure time and improves the treatment effects, especially in the right colon.

Abstract Background The efficacy of the hanging maneuver for the retropancreatic nerve plexus (RNP) to enhance the confirmation of the margin status and to facilitate en-bloc resection for pancreatoduodenectomy (PD). In this report, we present the knack and pitfall of the hanging maneuver of the RNP. MethodsThe exit of the hanging maneuver of the RNP is the left part of the superior mesenteric artery (SMA), and the entry is the cranial part of the celiac axis. The entry of the hanging maneuver was connected to the dissection line on the right side of the celiac axis. Thereafter, the tape of the hanging maneuver was pulled to the right side, and the RNP was deployed widely. Finally, the RNP was easily dissected using a sealing device other than IPDA ResultsIt is important to clarify the entrance and exit of the hanging taping in this procedure. This permitted the wide spaces between the SMA, SMV, and the resected side, and it was easier to identify the IPDA. By traction of the hanging maneuver tape, a clear line may be drawn between the resection side and the remaining side. ConclusionsWith the correct implementation of the hanging maneuver, we believe that it would be possible to obtain reliable R0 resection as well as a reduction in blood loss and operation time.

Background: Although right colon cancers mostly grow intraluminally, they may rarely invade neighboring organs without distant organ metastasis. En bloc resection is required for R0 resection in pancreas and duodenum-invasive right colon tumors. Despite the high mortality and morbidity rates, the en bloc right hemicolectomy and pancreaticoduodenectomy (RHPD) procedure can be safely performed in centers experienced in colorectal and hepatobiliary surgery. Objective: In this study, we aimed to share the results of our patients who underwent en bloc pancreaticoduodenectomy in addition to right hemicolectomy for cases with locally advanced right colon cancer. Materials and Methods: Patients who were operated on the right colon cancer between January 2010 and March 2018 were retrospectively screened. Patients who underwent RHPD due to locally advanced colon cancer invading the duodenum and pancreas were included in this study. RHPD was performed in cases where radical resection was deemed appropriate, and R0 resection could be performed. Demographic information, intraoperative and postoperative findings, and long-term follow-up data of the patients were recorded. Results: Six cases underwent RHPD. All of the cases were male, and the mean age was 67 ± 6. Proximal PD was performed in five cases, and total PD was performed in one case. SMV reconstruction was performed in one case with an SMV invasion. One case died due to pneumonia and anastomotic leak in the postoperative period. The other five patients had a mean disease-free survival of 29.2 ± 14.7 months. The 1 and 2-year survival rate was 66.6% and 66.6%, respectively. Conclusion: RHPD is a surgical operation that can be performed safely in experienced centers with acceptable mortality and morbidity rates in cases suitable for R0 resection.
