Properly performed, esophagogastrectomy is a safe esophagus and attention to the details of the operative operation with good symptomatic and nutritional results. If a tumor extends into the stomach, a significant distance either along the lesser curvature or into the fundus, a signifi- cant proximal gastrectomy is necessary for adequate tumor Carcinoma of the Cardia Region margin. If resection of more than 50 % of the stomach is required for tumor margins or if the anastomosis is less than Resection of lesions of the distal esophagus and gastric car- 10 cm from the pylorus, a total gastrectomy with Roux-en-Y dia with esophagogastric anastomosis is no longer an opera- esophagojejunostomy gives a much more satisfactory result.

Continuing epidural analgesia with esophagectomy is an option for lesions in the distal 10 cm of patient control after surgery has been an important advance. The use of minimally invasive approaches Although return of normal appetite and meal volume is utilizing laparoscopy and thoracoscopy have largely sup- slow, most patients have no dietary restrictions after the planted the left thoracoabdominal approach with the patient early narrowing of the anastomosis due to edema has in the lateral position for tumors whose proximal extent on resolved. A com- bined minimally invasive operation is rapidly becoming the approach of choice. Gouge lateral position for bulky tumors of the distal esophagus and in the neck is minimally (if any) longer than for an for salvage surgery when neoadjuvant therapy has failed to anastomosis at the apex of the thorax. The direct visualization of both chest been toward anastomosis in the neck, with experience an and abdomen is a great advantage for this palliative surgery, intrathoracic anastomosis is no more difficult in minimally and anastomosis in the chest is easily accomplished. As the incidence of anastomotic failure of intrathoracic anas- tomoses has been reduced to an uncommon event, the previ- Carcinoma of the Middle ous arguments about safety have lost their force. As already mentioned, the use of agus is subtotal resection following full mobilization of the the combined or semi-mechanical anastomosis in the neck stomach. The anastomosis should be con- for the back of the anastomosis and sutures for the front, cer- structed with an end-to-side or side-to-side technique at the vical leaks are more likely to remain localized or drain ante- apex of the right chest or in the neck. If it does not drain exteriorly, a cervical leak can track at the apex of the chest usually provides at least as much caudad and cause thoracic mediastinitis. The success often caused strictures that require dilation and can be diffi- rate of cervical anastomoses has been improved by the cult to manage with circular anastomoses, but the problem development of the semi-mechanical technique of anasto- seems less common with the combined technique. The same considerations of anastomosis has improved neither local recurrence nor long- blood supply and lack of tension apply. The tumor must be staged as completely as possible with radiation and chemotherapy and then reevaluated for prior to operation to ensure resectability because the surgeon surgical treatment after completing the course of neoadjuvant cannot assess local fixation until after completion of the therapy. For patients with significant invasion beyond the abdominal mobilization if the thoracic phase is done second. Doing the thoracic mobilization first has the advan- for palliation or even with curative intent after such tage of evaluating the local condition early in the operation, treatment. It is doubtful that thoracotomy so the substantial increase in operating time is heroic measures can prove more beneficial than a palliative not an issue. Distant approach only for mid-esophageal lesions that are clearly metastases are not a contraindication to palliative resection confined to the wall of the esophagus to avoid injury to major of a locally resectable tumor, but they do preclude cure at the vessels and the trachea. The patient’s condition and the gus is not as feasible in the mid- and upper esophagus as it is potential benefit must be carefully weighed when deciding in the lower third and cardia because of the adjacent respira- whether to resect for palliation. For such a patient, the mosis when the location of the tumor permits rather than ability to swallow can significantly enhance the quality of using a cervical anastomosis on principle in open surgery.

This operation is technically similar to Heller’s operation done for achalasia of the cardia or Ramstedt’s operation done for congenita! The sigmoid colon must be carefully separated from the left pelvic wall dividing peritoneal adhesions through a blood-less plane cheap trazodone 100 mg otc treatment 3rd degree heart block, so that the bowel may be held out through the wound purchase 100mg trazodone with mastercard medications 73. A preliminary incision is made with a scalpel starting from the rectosigmoid junction and proceeding upwards on the exact antimesenteric border of the colon over the thickened bowel between the two antimesenteric teniae cheap trazodone 100 mg online treatment 3rd degree heart block. The incision is carried on proximaliy for 8 to 12 inches till normal unthickened bowel is reached and then for an inch or so further. It is important that the bowel should be held straight, so that the incision is on the relatively blood-less midline. If bleeding occurs, a wet swab should be applied while the other part of the incision is deepened. It may be of assistance to inject saline with or without adrenaline along the line of incision. After preliminary incision, the cut is deepened by snipping the circular fibres with the fine scissors till the mucosa bulges throughout the length of the wound. Accuracy of division is assisted by maintaining gentle retraction on the lips of the incision by pairs of fine tissue forceps. If it occurs, all that is necessary is to suture the mucosa with fine atraumatic catgut. Presence of pus or active peritonitis found on laparotomy is an absolute contraindication-far this operation. This abscess may in turn burrow into one of the viscera which contributed to the walling-off process and thus an internal fistula develops. Only occasionally the pericolic abscess may burst into the free peritoneal cavity producing purulent peritonitis. Also rare is that the initial perforation has not been walled-off, so that free perforation occurs with a chance of generalised faecal peritonitis. When acute inflammation has completely subsided, elective operation should be called for. In more infective cases, the diseased bowel is resected, end-to-end anastomosis is performed with a proximal decompressing colostomy. Another procedure may be adopted in which the diseased bowel is mobilised and resected. The distal bowel is either brought out as a mucous fistula or the end is closed and left in situ (Hartmann procedure). The peritoneal cavity is obviously irrigated with antibiotics and drains are placed. Partial obstruction may be due to inflammation, spasm and oedema with an element of paralytic ileus. Complete obstrjetion may occur due to repeated episodes of diverticulitis with fibrosis and stenosis. Straight X-ray of the abdomen is valuable to differentiate between small and large bowel obstructions. The main treatment of obstruction with diverticulitis is diverting transverse colostomy and primary resection of the bowel with anastomosis. In some cases when proximal distension is much, immediate transverse colostomy is performed and an interval of about 3 months is allowed before resection is carried out. If carcinoma is suspected, primary resection is more justified, but in hazardous cases one may resort to resection 2 to 3 weeks after colostomy. Colocutaneous fistulas (external fistula) rarely occur sponta neously, but are common postoperative complications through the incision or drainage site. Pneumaturia (air in the urine) and Faecaluria (faeces in the urine) are diagnostic of colo-vesical or colo-ureteric fistulas. Sigmoi doscopy cannot demonstrate fistula, barium enema may sometimes demonstrate the fistula. In case of colouterine fistula, histerectomy with resection of involved colon is performed. Similarly in case of coloenteric fistula segment of ileum and diseased bowel resected. The diseased bowel is resected and the proximal colon is brought out as end colostomy. Sometimes proximal to the diseased colon is incised, the proximal colon is brought out as an end colostomy and the distal portion is sutured. When the inflammation has subsided adequate resection is performed and end-to-end anastomosis is done. Varying degrees of circulatory impairment may occur to the involved bowel by twisting of the root of the mesentery. In the colon, volvulus in most frequently seen in the sigmoid colon (90%) and is occasionally seen (10%) in the caecum when it is more mobile. Volvulus of transverse colon is extremely rare so is volvulus of the small intestine. Dilatation and lengthening of chronically distended colon is responsible for volvulus. It is quite uncommon for sigmoid volvulus to occur in a person who leads an active life and has no serious mental or physical illness, (iii) Congenital megacolon may be present in subclinical form throughout life. This probably accounts for only a small percentage of cases of sigmoid volvulus, (iv) It may occur in acquired megacolon, a complication of Chagas’ disease. When the sigmoid loop has rotated 1V turns the veins a re compressed2 and the loop becomes greatly congested. If the sigmoid loop has turned more than 1V turns, arterial supply is also cutoff2 and the loop soon becomes gangrenous. It must be remembered that sigmoid colon turns in anticlockwise direction for volvulus to occur. Sometimes a previous history of acute abdominal pain on the left lower quadrant may be felt due to partial volvulus. This volvulus untwists itself and is followed by passage of large quantities of flatus and stool with relief of Flg. This is soon followed by progressive marked abdominal distension with complete constipation and absence of passage of flatus. In the beginning the distension is only in the left lower quadrant, but soon involves the whole abdomen. Hiccough and retching may occur early, but nausea, vomiting and dehydration occur after several hours. Variable distension of colon proximal to the obstruction and of the small bowel may be shown dependingon the duration of obstruction, (ii) Barium enema radiography is usually not necessary.

Stimulation of the fascial mechanoreceptors (A-δ and C-fbers), like in tissue manipulation therapy, exerts efect 13 also on the autonomic nervous system. This autonomic efect will cause changes in local fascial capillary dynamics, intra- fascial smooth muscles relaxation, and change in global mus- cle tone via hypothalamic tuning. Te hypothalamus is tuned by the autonomic nervous system afer stimulation of the fascial mechanoreceptors (A-δ and C-fbers), which will rust in change in global skeletal muscles tone. This efect seen in tissue manipulation therapy or deep tissue massage for skel- etal muscles is also true for trigger points efect on the central nervous system. Another example of myofascial–nervous system interac- tion is seen in a technique known as “deep visceral massage,” which targets tissue manipulation of the visceral fascia, which in turn stimulates the mechanoreceptors of the enteric sys- tem.
