Superior mesenteric artery (SMA) syndrome is one of the rare causes of small bowel obstruction. It develops following a marked decrease in the angle between SMA and the abdominal aorta due to weight loss, anatomical anomalies, or following surgeries. Nutcracker syndrome in the left renal vein may also occur following a decrease in the aortomesenteric angle. Though SMA syndrome and renal nutcracker syndrome share the same pathogenesis, concurrent development has rarely been reported. Herein, we report a 23-year-old healthy male diagnosed with SMA syndrome and renal nutcracker syndrome due to severe weight reduction...

Injury to the nerves of the aortic- and superior hypogastric plexuses during retroperitoneal surgery often results in significant post-operative complications, including retrograde ejaculation and/or loss of seminal emission in males. Although previous characterizations of these plexuses have done well to provide a basis for understanding the typical anatomy, additional research into the common variations of these plexuses could further optimize nerve-sparing techniques for retroperitoneal surgery. To achieve this, the present study aimed to document the prevalence and positional variability of the infrarenal lumbar splanchnic nerves (LSNs) through gross dissection of 26 human cadavers...

Endovascular fenestration on the abdominal aorta is effective for preventing visceral malperfusion in aortic dissection. We report a case of stented balloon fenestration before residual entry repair using the frozen elephant trunk technique for chronic aneurysmal dissection after ascending aortic replacement for DeBakey I aortic dissection. We recognized poor communication between the true lumen and false lumen in the abdominal aorta, and visceral perfusion depended almost entirely on the proximal large entry...

Arteriovenous malformations (AVM) of the inferior mesenteric artery are rare. They may be primary (congenital or idiopathic) or secondary (acquired) after trauma or of iatrogenic origin. Of the abdominal AVM, the inferior mesenteric trunk is the least commonly involved. Most reported cases are of iatrogenic origin, resulting from colon surgery. Only 17 cases have been described and published in the literature. The objective of this work is to make known a case treated in our center. We present a case of 73-year old male, who came to the emergency service with symptoms of abdominal distension, pain lasting 48 hours along with months of diarrhoea...

Total robotic resection of mid- and low rectal cancers confers technical advantages within the confines of the pelvis and allows difficult rectal cancer cases to be performed efficiently with less risk of conversion to open. To maximize the advantage of robotic surgery, we utilize the technique of single docking totally robotic dissection for rectal cancer for both the Da Vinci Si and Xi Surgical Systems. All steps are performed robotically, with the surgery divided into two phases. The first phase consists of inferior mesenteric artery and vein ligation, sigmoid and descending colon mobilization and splenic flexure takedown...

Total colectomy with ileal pouch-anal anastomosis (IPAA) is considered the standard procedure for the surgical management of ulcerative colitis. Despite the widespread utility of the procedure, as many as 75% of patients who undergo IPAA, experience at least 1 complication. This review highlights difficult intraoperative scenarios and complications of pouch surgery in children, including intraoperative, postoperative, and functional complications. Intraoperative scenarios include insufficient mesenteric length and positive leak tests...

Background: Polyarteritis nodosa (PAN) is a medium vessel vasculitis which causes significant morbidity and mortality. Usually, it presents with constitutional symptoms with angiographic evidence of aneurysms or segmental stenosis of arteries of mesenteric or renal vasculature. It is exceedingly uncommon for PAN to present with symptomatic progressive intermittent claudication. Case Presentation: We describe a 60-year-old male who presented with rapidly progressive intermittent claudication of his right leg...

Anastomotic leakage is more frequently reported in colonic anastomoses. Ischemia reperfusion injury is one of the main reasons for anastomotic leakage. Simvastatin is known to prevent tissue damage induced by free oxygen radicals after ischemia reperfusion injury. The effect of simvastatin on colonic anastomosis impaired by ischemia reperfusion injury is investigated. Single layer, end-to-end colocolic anastomosis after 0.5-cm colon resection was performed in Wistar Albino rats. In Group 1 (control) (n = 10), colonic anastomosis without I-R was performed...

BACKGROUND: The level of inferior mesenteric artery (IMA) ligation for anterior resection of rectal cancer has several considerations concerning oncological outcomes. The primary endpoint of this randomized controlled trial (RCT) was to assess bowel function between high and low ligation. This study was intended to clarify oncological outcome as the secondary endpoint. OBJECTIVE: The aim of this study was to assess in a prospective RCT whether the ligation level of the IMA in rectal cancer influences oncological outcomes...

Esophageal perforation is a rare but potentially fatal complication of robot-assisted thyroidectomy (RAT). Herein, we report the long-term outcome of an esophageal reconstruction with a jejunal free flap for esophageal rupture after RAT. A 33-year-old woman developed subcutaneous emphysema and hoarseness on postoperative day1 following RAT. Esophageal rupture was diagnosed by computed tomography and endoscopy, and immediate surgical exploration confirmed esophageal rupture, as well as recurrent laryngeal nerve injury...

INTRODUCTION: Borderline resectable pancreatic cancer (BRPC) can involve the portal vein, superior mesenteric vein, superior mesenteric artery, coeliac axis or hepatic artery, and has a high probability of positive surgical margins and poor prognosis after resection. Neoadjuvant chemoradiation is expected to provide substantial local control and prolong survival in patients with BRPC. METHODS AND ANALYSIS: This open-label, multicentre, prospective phase II trial will assess S-1 with concurrent radiotherapy as preoperative treatment for BRPC...

This study is to prospectively evaluate the efficiency of sonography for volvulus diagnosis in neonates with clinically suspected intestinal malrotation.A total of 83 patients with suspected intestinal malrotation who underwent detailed abdominal sonography and upper gastrointestinal contrast study were included. Malrotation was characterized by inversion of the superior mesenteric artery (SMA) and superior mesenteric vein (SMV) in sonographic examination. The "whirlpool sign" of Color Doppler Sonography was recognized as a characteristic for malrotation with volvulus...

Midgut malrotation and incomplete rotation are common causes of neonatal intestinal obstruction. At end of 10 week of intrauterine life, cecum will be placed in subhepatic region temporarily and descends to right lower quadrant by eleventh week. Arrest of cecum in subhepatic region or undescended cecum is a rare congenital anomaly of mid gut. Usually, it remains asymptomatic and is diagnosed incidentally. If any pathology occurs in anomalous part, like appendicitis then the diagnosis and treatment will be challenging in all age groups...

Lymph node dissection is a critical part of surgery for colorectal cancer. Japanese D3 and complete mesocolic excision are two unique principles for lymph node dissection in colorectal cancer. Laparoscopic surgery magnifies the targets and provides insight about the micro-anatomy through high-quality, high-definition imaging, which benefits the surgeon. Although laparoscopic colorectal resection is feasible, there is no universal procedure. We describe in detail the anatomy viewed during lymph node dissection around the inferior mesenteric artery...

REVIEW
Manpreet Singh, Brit Long, Alex Koyfman
Mesenteric ischemia has 4 etiologies: arterial embolus, arterial thrombosis, venous thrombosis, and nonocclusive. No history or physical examination finding can definitively diagnose the condition. A wide variety of presentations occur. Pain out of proportion and gut emptying may occur early, with minimal tenderness. Once transmural infarction occurs, peritoneal findings and tenderness to palpation may occur. Physicians must be suspicious of pain out of proportion and scrutinize risk factors. Computed tomography angiography is the best imaging modality...
