A complete dissection of infrapyloric lymph nodes is the key to a curative gastrectomy, which can be sometimes technically challenging in laparoscopic surgery.
One hundred and eighteen patients with ...gastric cancer undergoing laparoscopic gastrectomy with D2 lymphadenectomy in which the infrapyloric lymph nodes were dissected through the right bursa omentalis approach were included. The clinicopathologic characteristics and surgical outcomes were analyzed retrospectively.
The laparoscopic gastrectomy with D2 lymphadenectomy was successful in all 118 patients with no open conversion. The mean operation time was 246.6 ± 45.7 min. The mean estimated blood loss was 87.0 ± 35.9 mL. Postoperative complications occurred in 17.8% of the patients, which were treated successfully with conservative therapy or aspiration in all. There were no No.6 lymphadenectomy-associated complications, such as injury of transverse colon, vessels of mesocolon, pancreas or duodenum, no pancreatitis, pancreatic leakage or postoperative hemorrhage. The mean postoperative hospital stay was 9.6 ± 3.7 days. On average, the total lymph nodes harvested were 36.8 ± 12.9, in which the ones from the infrapyloric area were 5.1 ± 3.1.
Laparoscopic dissection of infrapyloric lymph nodes through the right bursa omentalis approach seems to be feasible and safe, facilitating a more complete No.6 lymphadenectomy for gastric cancer.
Background
Bursectomy is regarded as a standard surgical procedure during gastrectomy for serosa-positive gastric cancer in Japanese gastric cancer treatment guidelines (Japanese Gastric Cancer ...Association in Gastric Cancer 14:113–123,
2011
). As a consequence, bursectomy is widely performed in open gastrectomy. However, laparoscopic gastrectomy with bursectomy is rare. Based on our previous experience of laparoscopic bursectomy in distal gastrectomy (Zou et al. in Oncol Lett 10:99–102,
2015
), herein, we described the technique of totally laparoscopic radical total gastrectomy with complete bursectomy using an outside bursa omentalis approach.
Methods
Firstly, the transverse mesocolon and distal gastric membrane were separated from right to left, and the right gastroepiploica vessels were ligated at root with No. 6 lymph nodes (LNs) dissection followed by the pancreas membrane dissection from pancreas head to pancreas tail. Secondly, the anterior plane of transverse mesocolon was dissected from left to right starting from the lower pole of spleen, and the membrane of pancreas tail was separated to combine the pancreas anterior plane with No. 4s, 10, 11d and 2 LNs dissection. Thirdly, the lesser omental was dissected from right to left with No. 5 and 12a LNs dissection, and the duodenum was transected. Then, the No. 7, 8, 9 and 11p LNs were dissected followed by No. 1 LNs dissection. Finally, a Roux-en-Y esophagojejunostomy was carried out intracorporeally with a linear cutter.
Results
Thirty-two patients with advanced proximal gastric cancer underwent laparoscopic total gastrectomy with complete bursectomy using an approach outside bursa omentalis. One bowel obstruction and one pulmonary infection were recorded and cured with conservative measure. The mean operative time was 253.3 ± 31.3 min with a mean blood loss of 90.5 ± 23.1 ml. The mean length of stay was 10.6 ± 2.6 days.
Conclusion
Laparoscopic radical total gastrectomy with complete bursectomy using an outside bursa omentalis approach is feasible and safe in experienced hands with favorable short outcome. Further studies were needed for its advanced application.
Background
Bursectomy is regarded as a standard surgical procedure during gastrectomy for serosa-positive gastric cancer in Japan. There is little evidence, however, that bursectomy has clinical ...benefit. We conducted a randomized controlled trial to demonstrate non-inferiority of treatment with the omission of bursectomy.
Methods
Between July 2002 and January 2007, 210 patients with cT2–T3 gastric adenocarcinoma were intraoperatively randomized to radical gastrectomy and D2 lymphadenectomy with or without bursectomy. The primary endpoint was overall survival (OS). Secondary endpoints were recurrence-free survival, operative morbidity, and levels of amylase in drainage fluid on postoperative day 1. Two interim analyses were performed, in September 2008 and August 2010.
Results
Overall morbidity (14.3%) and mortality (0.95%) rates were the same in the two groups. The median levels of amylase in drainage fluid on postoperative day 1 were similar in the two groups (
P
= 0.543). In the second interim analysis, the 3-year OS rates were 85.6% in the bursectomy group and 79.6% in the non-bursectomy group. The hazard ratio for death without bursectomy was 1.44 (95% confidence interval CI 0.79–2.61;
P
= 0.443 for non-inferiority). Among 48 serosa-positive (pT3–T4) patients, the 3-year OS was 69.8% for the bursectomy group and 50.2% for the non-bursectomy group, conferring a hazard ratio for death of 2.16 (95% CI 0.89–5.22;
P
= 0.791 for non-inferiority). More patients in the non-bursectomy group had peritoneal recurrences than in the bursectomy group (13.2 vs. 8.7%).
Conclusions
The interim analyses suggest that bursectomy may improve survival and should not be abandoned as a futile procedure until more definitive data can be obtained.
The exceptional case of the right gastroepiploic artery (RGE) arising from the dorsal pancreatic (DP) artery in an individual affected by hepatocellular carcinoma is presented. This anatomic variant ...was demonstrated with a selective angiography of the common hepatic artery that showed a distinct DP artery branching from the injected artery. The DP artery gave off regular pancreatic branches and continued as a long and winding vessel that was identified as the RGE by its general course, the anterior epiploic branches arising from it, and the injection of the distal splenic artery, possibly via the anastomosis with the left gastroepiploic artery. The anatomy of the RGE has few variations, mostly limited to its origin from the superior mesenteric artery. Arising of the gastroepiploic artery from the DP artery has never been previously reported and represents an unexpected possible anatomic variant of which general and heart surgeons should be aware. In particular, this case is of interest in surgical procedures involving resection of the head of the pancreas, gastrectomies or coronary artery bypass grafting using the RGE. The embryology underlying the development of this anatomic variation is reviewed.
The aim of the present study was to inquire into the feasibility, surgical skills required and short-term effect of a laparoscopic resection of the bursa omentalis and lymph node scavenging with ...radical gastrectomy. In this study, the clinical data of 18 patients who received a laparoscopic resection of the bursa omentalis with radical gastrectomy in the Department of Gastrointestinal Surgery, Guangdong Province Hospital of Traditional Chinese Medicine (Guangzhou, Guangdong, China) during the period between January 2012 and January 2014. A retrospective analysis was performed and the surgical duration, bursa omentalis resection time, amount of bleeding during the surgery, post-operative complications associated with the surgery, length of hospital stay, number of lymph nodes scavenged and short-term follow-up results were assessed. The results indicated that all of these 18 patients successfully received a resection of the bursa omentalis and no one required conversion to open surgery. The mean surgical duration was 289.3±30.3 min, the bursa omentalis resection time was 46.1±18.6 min and the amount of bleeding was recorded as 35.5±6.5 ml in these patients. No patients suffered from post-operative complications, such as pancreatic fistulae, anastomotic fistulae, intestinal obstructions or succumbing to the surgery, and no patients succumbed within a 6-month follow-up period. In conclusion, for advanced gastric carcinoma, laparoscopic resection of the bursa omentalis and lymph node scavenging with radical gastrectomy is feasible. In addition to meeting the requirement that the operator should be skilled and experienced in open bursa omentalis resection, and have well-knit basic skills in using a laparoscope, attention must also be paid to the construction of the surgical team.
An 81‐year‐old man, who experienced upper abdominal pain after shoveling snow, was admitted to a local hospital where a computed tomography (CT) showed a cystic lesion adjoining the pancreas. He was ...transferred to our department for detailed investigations and treatment. On ultrasonography, a tumor of the caudate lobe of the liver, with which the cystic lesion was continuous, was seen. The tumor of the caudate lobe of the liver was enhanced in the early phase of the CT but was washed out in the delayed phase. Subsequently, T1‐weighted and T2‐weighted magnetic resonance imaging (MRI) images showed a low intensity and a high intensity, respectively. Because the cystic lesion was continuous with the tumor of the caudate lobe of the liver, its CT value was higher than that of water, and both the T1‐weighted and T2‐weighted MRI images showed a high intensity, which was attributed to a hematoma. Examination of the image suggested that rupture of a hepatocellular carcinoma (HCC) might have caused intracavitary hemorrhage. After the HCC was treated by transcatheter arterial embolization therapy, the patient was discharged. Subsequently, tumor enlargement was confirmed, and surgical removal of the tumor was conducted at the hospital where the patient had originally presented. On histology, moderately differentiated HCC was diagnosed, but the cyst‐like lesion was confirmed to be a hepatic subcapsular hematoma extending into the bursa omentalis. Although ruptured HCC often causes intraperitoneal bleeding, this rare case showed a cyst‐like imaging finding in the form of a subcapsular hematoma within the bursa omentalis.
We report a case of a 45-year-old man with acute pain in the left upper abdominal quadrant. Extensive diagnostic workup remained inconclusive. An exploratory laparotomy revealed herniation of the ...entire ascending colon, together with a part of the terminal ileum through the foramen of Winslow into the bursa omentalis. The internal hernia was further complicated by a perforated appendicitis within the bursa, explaining the acuteness of the symptoms. Reduction of the hernia, appendectomy and colopexy were performed consequently. This would be the first reported case of a perforated appendicitis within the lesser sack.
We describe an unusual case of biliopancreatic fistula, free perforation, and subsequent abscess formation within the lesser peritoneal sac associated with intraductal papillary mucinous carcinoma ...(IPMC). A 71-year-old man presented with general fatigue and loss of appetite that had persisted for 1 month. Abdominal computed tomography (CT) revealed findings consistent with an intraductal papillary mucinous neoplasm (IPMN) of the pancreas, accompanied by abscess formation in the bursa omentalis. Gastrointestinal fiberscopy revealed a swollen papilla of Vater expanded by sticky mucus, and a communication between the pancreatic duct and bile duct was demonstrated by the injection of indigo carmine solution into the pancreatic duct. Percutaneous transhepatic abscess drainage (PTAD) was performed on the day of admission. After this procedure, the patient was managed for 1 month and supported nutritionally with glycemic control for diabetes mellitus. After admission, the patient had an episode of obstructive jaundice that was treated by retrograde biliary drainage. Pancreaticoduodenectomy with lymph node dissection was then performed. Pathological examination revealed IPMN with patchy, scattered carcinoma of the pancreatic head and uncinate process with the formation of a biliopancreatic fistula. Bile duct epithelium in the area of the biliopancreatic fistula demonstrated atypical papillary epithelium suggestive of tumor invasion.
Although paraoesophageal hernias remain 30% asymptomatic, when diagnosed they have to be operated because of their fatal complications such as ischaemia, bleeding and perforation. The mortality rate ...increases to twenty times in emergency cases when it is compared with elective ones. Site of gastric perforation may be directed towards bursa omentalis as well as to peritoneal cavity. A case of a volvulated paraoesophageal gastric herniation ruptured to bursa omentalis is discussed with the review of the literature.
