BACKGROUND
In pancreaticoduodenectomy (PD), the approach to superior mesenteric artery (SMA) is a critical process that supports adequate surgical margins and radicality for pancreatic tumors. In most of the reports on laparoscopic PD, the right-sided approach in which the jejunum is pulled out to the right side for peri-SMA dissection is used, since the left side of the SMA is difficult to dissect, and the only way to do this is to dissect the vein first.
METHODS
We devised a method to simplify and safely perform peri-SMA dissection by reversing the process, starting from the left side of the SMA. The first step involves the mobilization of the pancreatic head, which allows for rotation around the SMA. The second step involves the dissection of the left side of the SMA and transection of the jejunum. The key point is to change the incision line between the anterior and posterior mesojejunum. The third process includes the inferior pancreatoduodenal artery (IPDA) and first jejunal artery (J1A) dissection, which can be easily performed from the left side because the SMA rotates by simply continuing the dissection along the previously exposed SMA, and the IPDA/J1A are safely dissected at the root because they are drawn to the left side. The remaining processes are performed on the right side.
RESULTS
This method was performed in 16 cases, and in most cases IPDA/J1A were divided from the left side.
CONCLUSION
The technique for SMA dissection from the left posterior side was described with illustrations and video. Our method allows safe oncologic dissection around SMA avoiding anatomical misorientation during laparoscopic PD.

Review
In the past 40 years, the incidence of esophagogastric junction cancer has been gradually increasing worldwide. Currently, surgical resection remains the main radical treatment for early gastric cancer. Due to the rise of functional preservation surgery, proximal gastrectomy has become an alternative to total gastrectomy for surgeons in Japan and South Korea. However, the methods of digestive tract reconstruction after proximal gastrectomy have not been fully unified. At present, the principal methods include esophagogastrostomy, double flap technique, jejunal interposition, and double tract reconstruction. Related studies have shown that double tract reconstruction has a good anti-reflux effect and improves postoperative nutritional prognosis, and it is expected to become a standard digestive tract reconstruction method after proximal gastrectomy. However, the optimal anastomoses mode in current double tract reconstruction is still controversial. This article aims to review the current status of double tract reconstruction and address the aforementioned issues.

BACKGROUND
Chemoradiotherapy is a standard treatment for functional preservation in patients with advanced head and neck carcinoma. However, chemoradiotherapy increases the risk of postoperative complications.
AIMS/OBJECTIVES
We report the usefulness of reconstruction using a free jejunal patch flap in treating recurrence or residual head and neck carcinoma after radiotherapy. Furthermore, we investigated the factors for the occurrence of postoperative complications in patients who underwent salvage surgery using a free flap transfer.
MATERIAL AND METHODS
This study included 41 patients with head and neck carcinoma who underwent salvage surgery using a free flap transfer, including 11 patients who underwent reconstruction using a free jejunal patch flap. Prognostic analysis was performed for the development of complications.
RESULTS
Ten jejunal patch flaps survived without microvascular problems. One patient underwent revision reconstructive surgery because of flap failure. However, no patient had a pharyngocutaneous fistula. Oral intake could be resumed in all patients at a median 14 days postoperatively. Multivariate logistic regression analysis indicated that the use of cutaneous flaps was significantly associated with the development of complications.
CONCLUSIONS AND SIGNIFICANCE
Free jejunal patch flaps can be considered useful for head and neck reconstruction after radiotherapy for early intake resumption and complication prevention.

Journal of Gastroenterology May 2024The clinicopathological features and prognosis of primary small bowel adenocarcinoma (PSBA), excluding duodenal cancer, remain undetermined due to its rarity in Japan.
BACKGROUND
The clinicopathological features and prognosis of primary small bowel adenocarcinoma (PSBA), excluding duodenal cancer, remain undetermined due to its rarity in Japan.
METHODS
We analyzed 354 patients with 358 PSBAs, between January 2008 and December 2017, at 44 institutions affiliated with the Japanese Society for Cancer of the Colon and Rectum.
RESULTS
The median age was 67 years (218 males, 61.6%). The average tumor size was 49.9 (7-100) mm. PSBA sites consisted of jejunum (66.2%) and ileum (30.4%). A total of 219 patients (61.9%) underwent diagnostic small bowel endoscopy, including single-balloon endoscopy, double-balloon endoscopy, and capsule endoscopy before treatment. Nineteen patients (5.4%) had Lynch syndrome, and 272 patients (76.8%) had symptoms at the initial diagnosis. The rates for stages 0, I, II, III, and IV were 5.4%, 2.5%, 27.1%, 26.0%, and 35.6%, respectively. The 5-year overall survival rates at each stage were 92.3%, 60.0%, 75.9%, 61.4%, and 25.5%, respectively, and the 5-year disease-specific survival (DSS) rates were 100%, 75.0%, 84.1%, 59.3%, and 25.6%, respectively. Patients with the PSBA located in the jejunum, with symptoms at the initial diagnosis or advanced clinical stage had a worse prognosis. However, multivariate analysis using Cox-hazard model revealed that clinical stage was the only significant predictor of DSS for patients with PSBA.
CONCLUSIONS
Of the patients with PSBA, 76.8% had symptoms at the initial diagnosis, which were often detected at an advanced stage. Detection during the early stages of PSBA is important to ensure a good prognosis.

Review
BACKGROUND Schwannomas are tumors that arise from Schwann cells that surround and support nerve cells. Most common sites for presentations are head, neck, and extremities. Schwannomas of gastrointestinal tract are rare, slow-growing tumors, usually benign, arising from gastrointestinal tract's neural plexus. They are histologically distinguishable from conventional schwannomas that arise in soft tissue or the central nervous system. Preoperative diagnosis of gastrointestinal schwannoma is challenging, requiring immunohistological confirmation of the nature of the tumor. Here, we report a case of 57-year-old woman with an incidental finding of an asymptomatic submucosal jejunal schwannoma. CASE REPORT A 57-year-old woman with a medical history of hematological disorder underwent a contrast abdominal computed tomography as part of medical follow-up. The imaging revealed the presence of a jejunal mass. The patient underwent laparoscopic surgical resection of the lesion, followed by side-to-side jejuno-jejunal anastomosis with 4-cm clear surgical margins. The final pathologic study revealed the presence of jejunal schwannoma, as tested positive for S-100 protein. The patient was discharged home on the fourth postoperative day, having an uneventful recovery. CONCLUSIONS Jejunal schwannoma are usually benign and asymptomatic, and they are often discovered incidentally during diagnostic tests for other conditions; therefore, it should be included in the differential diagnosis of gastrointestinal tumors. Surgical treatment appears to be necessary to achieve a definitive diagnosis through a biopsy of the tumor tissue. Benign jejunal schwannomas have a good prognosis.

BACKGROUND
It remains unclear whether a tubed fasciocutaneous or jejunal free flap (FCFF and JFF) is preferable for reconstruction of circumferential pharyngolaryngoesophageal defects.
METHODS
All consecutive patients with circumferential pharyngolaryngoesophageal defects reconstructed with an FCFF or JFF between 2000 and 2022 were included. Outcomes of interest were rates of fistulas, strictures, and donor-site complications.
RESULTS
In total, 112 patients were included (35 FCFFs and 77 JFFs). Fistula and stricture rates were significantly lower following JFF compared to FCFF reconstructions, with 12% versus 34% (p = 0.008) and 29% versus 49% (p = 0.04), respectively. Severe donor-site complications leading to surgical intervention or ICU admittance only occurred after JFF reconstructions (18%, p = 0.007).
CONCLUSIONS
The high fistula and stricture rates in FCFF reconstructions and the rate of severe abdominal complications in JFF reconstructions illustrate inherent procedure-specific advantages and disadvantages. Relative pros and cons should be carefully weighed when tailoring treatments to the individual needs of patients.

Performing an intracorporeal esophagojejunostomy during laparoscopic-assisted total or proximal gastrectomy is challenging. We developed an ingenious method of overlapping esophagojejunostomy using a linear stapler to avoid stapler-related intraoperative complications. Following lymph node dissection, the esophagus was transected anterior-posteriorly. A linear stapler was used to divide the jejunum ∼20 cm distal to the Treitz ligament. A small enterotomy was then created 5 cm distal to the elevated jejunal stump to insert the linear stapler cartridge. An electronic knife was used to make a full-thickness incision, with the tip of the nasogastric tube (NGT) pressed against the posterior wall of the esophageal stump as a guide. Full-thickness sutures were placed on both the anterior and posterior walls of the entry hole in the esophageal stump to prevent the anvil fork from being misinserted into the submucosal layer of the esophagus. The thread on the posterior wall was guided through the port to the outside of the abdominal cavity, where the linear stapler was inserted to perform the side-to-side anastomosis. A 45-mm cartridge fork and an anvil fork were inserted into the elevated jejunum and esophageal stump entry holes, respectively, following which the esophageal stump was gently grasped. The thread on the posterior wall side was pulled from outside the abdominal cavity through the port. This step is necessary to close the gap between the esophageal and jejunal walls. After confirming that the anvil fork was not misinserted into the submucosal layer of the esophagus and that there was no gap between the esophagus and the elevated jejunum, the linear stapler was fired to create the anastomosis. The insertion hole was closed with hand-sewn sutures or linear staples to complete the esophagojejunostomy. Eleven patients underwent this procedure with no anastomotic complications. This method enables us to perform an easier and more stable esophagojejunostomy.

Review
Small bowel adenocarcinoma (SBA) is a rare tumor with an unfavorable prognosis, and due to its rarity, few studies on its treatment are available. Chemotherapy remains the standard of treatment in advanced disease. Recently immunotherapy has demonstrated to be a valid therapeutic option for many solid tumors. We reviewed the data published in literature to understand the impact of immunotherapy in this cancer.
