Such arguments become important in thinking about potential adverse consequences of laparoscopic approaches to the vagus and the need for acne when pregnant purchase 5 mg accutane mastercard, and choice of, drainage procedures. Only when one fully understands the physiologic rationale of highly selective vagotomy will be one sufciently motivated to do it well. First, it mediates receptive relaxation and gastric accommodation; that is, the relaxation of the gastric fundus when intraluminal pressures in the proximal esophagus and stomach are increased by To perform a complete vagotomy, access to the upper part of the stomach and lower esophagus is crucial. When access to the duodenum is required, as in a gastrectomy, excellent exposure is available through a chevron incision. However, in most patients, both thin and obese, a midline incision carried up along the xiphoid will be adequate. Some surgeons advocate routine mobilization of the left lobe of the liver by dividing the left triangular ligament. In: Schwartz held upward and to the right by a Richardson or Herringtontype retractor accessory. Care must be taken to place sponges or a pack between the retractor attachment and liver, and not to put much tension on the liver. When teaching this maneuver, it is not uncommon for the trainee to confuse the right crus of the diaphragm with the esophagus itself or even the posterior vagal trunk. Extra time spent at this juncture to correctly identify all structures is an essential aspect in teaching the operation. A Penrose drain can be passed around the junction in order to place more e ective downward traction on the gastroesophageal junction. When encircling the esophagus, the surgeon stays wide of the esophagus in order to prevent inadvertent entry into the lumen and to include the vagal trunks. In the course of this maneuver, the posterior vagal trunk usually will be palpated as a taut cord. A single anterior vagal trunk is usually identi ed in the anterior midportion of the esophagus, 24 cm above the gastroesophageal junction. At this level, however, it is not uncommon for vagal bers to be distributed between two or three smaller cords. A medium-sized clip is applied at the most superior end, and a clamp is applied inferiorly. If it has not been done, the esophagus should be more widely mobilized for a distance of 45 cm above the gastroesophageal junction. Smaller, individual vagal bers that ramify from the main trunks toward the lesser curvature and the cardiac notch then can be identi ed and cut or cauterized. A 2- to 4-cm segment is separated from surrounding tissues, its margins marked with clips, and resected. Major branches of the anterior vagus and the posterior vagal trunk should be sent to pathology for examination in frozen section. Anteriorly, the nerve of Latarjet is identi ed by following the anterior vagal trunk as it descends from the esophagus to the lesser curvature of the stomach. Frequently, the descending branch of the left gastric artery is in close proximity to the site where the hepatic/gallbladder branches take o toward the liver in the gastrohepatic (lesser) omentum.

In patients for whom further treatment is not being considered skin care lounge order 10 mg accutane with visa, either due to comorbid conditions or patient choice, an extensive evaluation for the extent of disease may be unjusti ed. In patients for whom only noncurative systemic chemotherapy is being considered, an evaluation should establish a baseline to facilitate monitoring of the response to treatment at all sites. In those who are or may become candidates for local therapy directed to the liver, it is important to exclude the presence of extrahepatic disease, particularly in the majority of these patients who are asymptomatic from their liver disease. Malignant tissue with relatively increased uptake can be seen as areas of increased signal relative to the surrounding less metabolically active normal tissue. Multiple bilobar metastases as well as involvement of hilar structures or the presence of periportal or celiac nodal disease may preclude resection. Not infrequently, patients who are considered preoperatively to be candidates for resection are found at operation to be unresectable because of previously unrecognized additional hepatic lesions. High-quality contrast-enhanced cross-sectional imaging is imperative for an adequate assessment of the liver prior to surgery. In addition, advanced postacquisition imaging techniques-such as three-dimensional reconstruction, volume-rendering, and digital subtraction angiography-may improve the ability to view the relationship of metastases to vital structures and determine resectability. In one report from Johns Hopkins, the non-therapeutic laparotomy rate decreased from 15% in the 1990s to approximately 5% in the more recent years. In some patients, however, a brotic or fatty liver, sometimes related to the use of preoperative chemotherapy, may reduce the ability to palpate small metastases. In some cases, an indentation or dimple on the capsule of the liver can provide a clue of the presence of a small metastasis below the surface, particularly in patients following a signi cant response to chemotherapy. Detection rate was found to be higher in those patients with multiple metastases (>3) and those in whom the index known lesions were hypoechoic22. Moreover, they found patients with isoechoic index lesions were associated with signi cantly higher rate of early intrahepatic recurrence, a surrogate for missed lesions. By improving the capability of detecting clinically occult metastases, patients with multiple unresectable metastases may be spared unnecessary hepatic resection. With recent re nements in laparoscopic ultrasonographic devices, intraoperative hepatic ultrasonography can now compliment visual laparoscopic assessment. First, non-therapeutic laparotomy rates are lower in this disease than in most other gastrointestinal cancers, resulting in less potential bene t. A more accurate understanding of liver structure, based on functional segmental anatomy, as well as advances Chapter 45 Hepatic Colorectal Metastases: Resection, Pumps, and Ablation 957 Selecting Patients for Surgical Resection Indications for surgical resection of hepatic colorectal metastases have undergone a major shift in the last decade. Previously, hepatectomy was not recommended in patients who had more than three or four metastases, hilar adenopathy, metastases within 1 cm of major vessels such as the vena cava or main hepatic veins, or extrahepatic disease. More recent studies demonstrate, however, that patients with these clinicopathologic factors can achieve long-term survival following hepatic resection and therefore should not be excluded from surgical consideration. An increasing number of studies also indicate that although survival may be reduced in patients with extrahepatic or periportal lymph node metastases, complete resection of these sites in conjunction with resection of hepatic metastases can result in long-term survival.
On the other hand acne 5 months postpartum buy cheap accutane 30 mg on line, those patients who do not su er from recurrent disease generally do well and typically experience good pouch function. Preservation of the colonic absorptive capacity may be bene cial also in the elderly patient. To avoid injury to pelvic sympathetic and parasympathetic nerves, the dissection should be undertaken close to the rectal wall. In the absence of signi cant perianal disease, the perineal dissection is best carried out along the plane between the internal and external sphincters. In the presence of signi cant perianal disease, a staged approach, as described previously, can be utilized as an option. Occasionally, however, because of extensive rectal disease, closure of the rectal stump may be technically challenging or not feasible, forcing the surgeon to proceed with a proctectomy in the face of perianal sepsis. Large open perineal wounds may be managed temporarily or de nitively with the assistance of the vacuum-assisted closure device. Abdominoperineal resection with end sigmoid colostomy has been associated in some reports with a high risk for stomal complications and recurrent disease in the proximal intestine when compared to total proctocolectomy with end ileostomy. Segmental involvement of the right colon should be managed by simple right hemicolectomy with ileotransverse anastomosis. For segmental disease involving the transverse colon, an extended right hemicolectomy is generally preferred to a segmental transverse colectomy. Such an approach may have a lower risk of recurrence compared to a segmental resection of the transverse colon. For disease in the descending or sigmoid colon, the appropriate surgery is more controversial. Presence and severity of concurrent perineal complications, the degree of fecal continence, and the natural history of the disease in the residual colon all play a role in deciding on the approach for each individual patient. Studies have indicated that segmental colonic resection with colocolonic anastomosis or even colonic strictureplasty can be performed with overall good results. Attempts at treating purulent collections with antibiotics alone are invariably unsuccessful. With surgical drainage of the abscess, the incision should be placed close to the anal margin. If a stula tract can be identi ed at the time of drainage of the suppuration, a loose seton may be placed to ensure adequate drainage. Uncomplicated submucosal or intersphincteric stulas are best treated with an initial trial of either metronidazole or cipro oxacin. Surgical stulotomies and cutting setons should not be used for suprasphincteric stulas and should also be avoided for most transsphincteric stulas. For complex stulas, the risk for surgical complications is higher and more aggressive medical therapy is warranted before surgery is recommended. With in iximab treatment, healing of complex perianal stulas is seen in 60% of cases. To provide for adequate drainage throughout the stula tract, many patients may bene t from placement of setons.
