Robotic pancreas-preserving total duodenectomy: first-world experience

Pancreas sparing total duodenectomy (PSTD) is an exceedingly rare procedure that is performed mostly for benign disease, widely involving the duodenum, that cannot be treated otherwise. PSTD requires meticulous dissection as well as reconstruction of both biliary and pancreatic drainage. Despite these technical aspects appear to be ideal for robotic assistance, robotic PSTD has not been described yet.Robotic PSTD was successfully performed in two patients. In both patients biliary and pancreatic drainage were reconstructed on the second jejunal loop, which was pulled in the duodenal bed. In the first patient, gastro-jejunostomy was performed on the blind end of the neo-duodenum (Billorth I type gastric reconstruction). In the second patient, gastro-jejunostomy was achieved in an antecolic position, 40 cm downstream the neo-ampulla in the second patient (Billorth II type gastric reconstruction). In both patients, indication to PSTD was duodenal polyps not amenable to endoscopic removal. The first patient suffered from prolonged delayed gastric emptying, but she is currently doing well 5 years and beyond after the procedure. The second patient complained of mild delayed gastric emptying that resolved spontaneously. He is now doing well 5 months after surgery.We have shown the feasibility of robotic PSTD in what we believe to be a world premiere. Further experience is required to refine the procedure and improve outcomes.

Laparoscopic pancreas-preserving near total duodenectomy for large villous adenoma in patients with total colectomy for familial adenomatous polyposis

Most familial adenomatous polyposis (FAP) patients undergo total colectomy, but duodenal polyposis develops in up to 90% of patients with FAP and a 4% to 18% risk of duodenal and ampullary cancer remains. Laparoscopic pancreas-preserving near total duodenectomy is thought to be a potential option and can be an effective approach to preserve the pancreas. A 48-year-old male patient, who underwent laparoscopic total colectomy with end ileostomy because of FAP with colorectal cancer, was diagnosed with a 20 mm-sized duodenal adenoma in the second to the third portion. The operation was performed on December 27, 2021. Near total duodenectomy was done and type II Billroth gastrojejunostomy was done. Laparoscopic pancreas-sparing duodenectomy is shown to be safe, with favorable short-term oncologic outcome compared to laparoscopic pancreatoduodenectomy in terms of less blood loss, faster recovery time, and much less total cost.

Hybrid laparoscopic pancreas-preserving subtotal duodenectomy for suspected early duodenal cancer: A case report

INTRODUCTION

Non-ampullary duodenal adenomas rarely show malignant potential. However, such adenomas located in the periampullary area are suspected of being malignant and require surgical treatment.

PRESENTATION OF CASE

A 75-year-old man presented with a 30-mm wide, endoscopically-unresectable laterally spreading tumor in the periampullary area. Biopsy showed a tubular adenoma; however, the size and color of the tumor strongly suggested malignancy. Therefore, a hybrid laparoscopic pancreas-preserving subtotal duodenectomy (HLPPSD) was performed. Laparoscopically, a Kocher maneuver was performed. The jejunum was divided 10 cm distal to the ligament of Treitz, and the duodenum was also divided at the supraduodenal-angle. The Shuriken method was applied, and the surgery converted to an open procedure. The common bile and pancreatic ducts were divided, and the subtotal duodenum and 10 cm of the jejunum were removed. Thereafter, the jejunal stump was hand-sutured to the duodenal stump. Cholangiojejunostomy and pancreatojejunostomy were performed under direct vision. Finally, an umbilicoplasty was performed. The histology revealed that the tumor was a carcinoma in situ.

DISCUSSION

Endoscopic resection is the first-choice for duodenal adenoma suspected of malignant potential. When the endoscopically-unresectable tumor is located in periampullary area, pancreatoduodenectomy is generally selected because ampulla cannot be preserved. However, HLPPSD is an alternative option.

CONCLUSIONS

Non-ampullary duodenal adenomas can be malignant when the tumor is large and red. In these cases, HLPPSD can be useful; less invasive than conventional pancreaticoduodenectomy; leaves only a 3-cm, round scar, in addition to the laparoscopic port scars; and combines the benefits of both open and laparoscopic surgeries.

Endocytoscopic observation with methylene blue staining for duodenal neoplasms associated with familial adenomatous polyposis

Duodenal cancer is a leading cause of death after colectomy in patients with familial adenomatous polyposis (FAP). Detailed endoscopic evaluation of duodenal lesions with potential for carcinoma development is therefore mandatory. Here we investigated the features of duodenal lesions in FAP patients using an endocytoscopy system (ECS). We retrospectively reviewed duodenal lesions in 15 cases of FAP using an ECS (GIF-H290EC) with methylene blue (MB) as the vital dye. With reference to the Spigelman classification, we investigated the number of lesions using white light (WL), narrow-band imaging (NBI), and MB staining. Using the maximum magnification power of the ECS we investigated the histology (duct openings or finger-like projections) and grade of dysplasia (presence or absence of enlarged oval-shaped nuclei) of the lesions. The number of duodenal lesions increased in ascending order of WL, NBI, and MB (P < 0.05). Among 51 MB-unstained lesions, 46 (90.2%) were proven to be duodenal neoplasms histologically. Duct openings were seen in 90.2% of tubular adenomas and tubulovillous adenomas. Finger-like projections were seen in 33.3% of tubular adenomas and in 88.2% of tubulovillous adenomas. Enlarged oval-shaped nuclei were observed in 100% of duodenal cancers, 33.3% of high-grade adenomas, and 9.4% of low-grade adenomas. MB staining allows more accurate detection of duodenal neoplasms in comparison to conventional WL and NBI observation. In cases of FAP, use of the maximum magnification power of the ECS may allow selection of lesions with high malignant potential.

Pancreas-sparing total duodenectomy for Spigelman stage IV duodenal polyposis associated with familial adenomatous polyposis: experience of 10 cases at a single institution

Duodenal cancer is a leading cause of death in patients with familial adenomatous polyposis (FAP). In patients with Spigelman's classification (SC) stage IV duodenal polyposis (DP), careful endoscopic surveillance by specialists or surgical intervention is mandatory. We herein report the surgical and pathological outcomes of FAP patients with SC stage duodenal polyposis undergoing pancreas-sparing total duodenectomy (PSTD), which has been rarely reported but seems optimal in such patients. PSTD and distal gastrectomy with Billroth-I type reconstruction in ten consecutive FAP patients with SC stage IV DP are reported. The median duration of surgery was 396 min (range 314-571 min) and the median estimated blood loss was 480 mL (range 100-975 mL). Significant postoperative complications included wound infection in 1 patient, pancreatic fistula [International Study Group on Pancreatic Fistula definition (ISGPF) grade B] in 4 patients. Histopathologic examinations revealed a well-differentiated carcinoma in situ in 3 patients and others were all adenomas. Over a median follow-up period of 15 months (range 9-29 months), 1 patient developed a stomal ulcer which improved with medical treatment. There were no patients with a body weight loss of ≥10 % relative to the preoperative body weight. No recurrence were experienced during the follow up period. Patients were free from postoperative diabetes mellitus. PSTD is a feasible and acceptable procedure in FAP patients with SC stage IV DP, in terms of surgical, pathological and clinical outcome. However, accumulation of the patients and long-term follow up study is necessary.

Duodenal adenocarcinoma: Advances in diagnosis and surgical management

Duodenal adenocarcinoma is a rare but aggressive malignancy. Given its rarity, previous studies have traditionally combined duodenal adenocarcinoma (DA) with either other periampullary cancers or small bowel adenocarcinomas, limiting the available data to guide treatment decisions. Nevertheless, management primarily involves complete surgical resection when technically feasible. Surgery may require pancreaticoduodenectomy or segmental duodenal resection; either are acceptable options as long as negative margins are achievable and an adequate lymphadenectomy can be performed. Adjuvant chemotherapy and radiation are important components of multi-modality treatment for patients at high risk of recurrence. Further research would benefit from multi-institutional trials that do not combine DA with other periampullary or small bowel malignancies. The purpose of this article is to perform a comprehensive review of DA with special focus on the surgical management and principles.

"High rate of recurrent adenomatosis during endoscopic surveillance after duodenectomy in patients with familial adenomatous polyposis"

Advanced duodenal adenomatosis in patients with familial adenomatous polyposis (FAP) is associated with a significant risk of duodenal carcinoma. Duodenectomy is sometimes indicated to prevent malignant transformation or to resect established carcinomas. Advanced recurrent adenomatosis and cancer formation in the neo-duodenum after duodenectomy in FAP have been reported. The aim of this study was to describe findings during endoscopic follow-up in a cohort of FAP patients after duodenectomy, to assess the indication and whether recommendations can be made for endoscopic surveillance. All FAP patients with a history of duodenectomy performed at a single tertiary referral centre between January 2000 and July 2011 were identified. Patient characteristics and postoperative upper endoscopic procedures were reviewed retrospectively. 19 patients, with a mean age of 49 years at the time of duodenectomy were identified. One patient was lost to follow-up. The majority of patients underwent prophylactic pancreas preserving duodenectomy (95%). Mean duration of postoperative follow-up in 18 patients was 78 months with 4 postoperative endoscopies on average. An increase in neo-Spigelman stage was seen in 9 patients, after an average interval of 35 months. Overall, newly formed adenomas in the neo-duodenum were found in 14 of 18 patients (78%), after a mean of 46 months after duodenectomy. Recurrent adenomas were mostly located in close proximity to the neo-papilla. This included advanced adenomas in 7 patients, warranting enteric re-resection in 2 patients. Continued intensive endoscopic surveillance is indicated after duodenectomy in FAP, especially of the area around the bilio- and pancreatico-enteric anastomoses.

Pancreas-sparing total duodenectomy for ampullary duodenal neoplasms

BACKGROUND

Ampullary and extensive periampullary lesions can be difficult to treat and often require pancreaticoduodenectomy (PD) for complete removal, even if benign. However, PD may be overtreatment for noninvasive lesions, and pancreas-sparing total duodenectomy (PSTD) is an emerging valid surgical option for selected cases.

METHODS

We reviewed patients undergoing PSTD at our institution over 16 months and a comparison group who had undergone PD for benign duodenal disease over the past 15 years. We also reviewed cases in the English-language literature and performed a meta-analysis of those patients who had undergone PSTD.

RESULTS

PSTD had been performed in four patients, who had an average hospital length of stay (LOS) of 13 days; two of them experienced complications. None required conversion to PD, experienced a postoperative fistula or endocrine or exocrine insufficiency, or required intensive care. Two of the PSTDs were performed laparoscopically. Open PD for benign duodenal disease was performed in 22 patients, with overall morbidity and pancreas fistula rates of 82 and 27 %, respectively. The meta-analysis found 128 unique cases of PSTD with morbidity and mortality rates of 46.4 and 2.3 %, respectively. Pancreaticobiliary leak was seen in 20 %, with an average LOS of 17 days.

CONCLUSIONS

Although PSTD can be used to avoid PD and can be performed laparoscopically, it is technically challenging and still associated with morbidity.
