tosis after splenectomy and stasis of blood in the stump of the splenic vein appear to predispose to PVT. 2 In Dr Atweh and associates’ patient, underlying diseases in- cluding malignancy, coagulation disorder, and thrombo- cytosis were not detected. At present it should not be concluded that splenectomy itself leads to PVT, because more evidence is required. It is still a controversial issue. Prospective studies are needed to determine the inci- dence, diagnosis, and treatment of PVT for patients who undergo splenecetomy, as Dr Atweh comments. Consid- ering previously mentioned symptoms and associated conditions like abnormal coagulation, cirrhosis, or trauma, careful followup after splenectomy using Dopp- ler ultrasonography may play an important role in the early detection and appropriate treatment for PVT.

Palliation of Proximal Gastric Cancer Nicola Di Lorenzo, MD, Ph D, FACS , Giorgio Coscarella, MD, Francesca Lirosi, MS , Achille Gaspari, MD, FACS Rome, Italy We were very interested in the article by Farrokh Saidi and associates, “A new approach to the palliation of ad- vanced proximal gastric cancer.” 1 The original technique of reconstruction proposed is very interesting for esoph- ageal cancer, and the functional results, as previously described by Dr Saidi in 1988 and 1991, 2 seem to be comparable (if not better) than those of transhiatal esophagectomy. Nevertheless, when applying the same technique for palliation of advanced cancer of the proximal stomach and cardia, some considerations should be pointed out. The authors seem to consider their operation as an alternative to esophagogastrectomy. In our opinion, sur geons should remember that this is not actually the mo common resection performed for palliation of proximal gastric cancer. This is especially true when facing pa- tients with “serosal extension, distal peritoneal implant regional nodes involvement, moderateascites, and . . . liver metastases.” Most of these patients need totalD1 gastrectomy, but a Roux-en-Y esophagojeju- nostomy can usually be performed through the abdo- men, freeing the esophagus trashiatally. It has been als demonstrated 3 that reconstruction of duodenal transit is not necessary, but, if required, it can be realized with a jejunalsegment, according to Longmire-Mouchet technique. The authors propose the colonic pull-through in the esophageal remnant, which resembles the Soave opera tion for Hirschprung’s disease. In this procedure, the muscular tunnel is very short; in Dr Saidi’s operation, the colon is forced for at least 25 cm in the esophageal muscular tube, although this was previously manually stretched, and the blood supply to the bowel could be compromised. It is well known that any intestinal seg- ment, when brought to the neck in the standard fashion can suffer venous engorgement, so some authors 4 have suggested a second anastomosis in the neck to increas blood drainage. This problem could be worsened having a narrower space. The same question was proposed in the comments to the cited articles, butno definitive answer was given. Emphasizing the swallowing effect o the esophageal tube, Dr Saidi reported his excellent clin ical results, but said that no manometric study had bee done. This investigation, together with perfusion stud- ies, could be very helpful in assessing the physiology of the transposed colon. Finally, we were very impressed by the in-hospital mortality rate (10%) in a selected group of patients with advanced neoplasms (70% of them were TNM Stage IV). As stated in an interesting survey by Gordon and associates, 5 cumulative in-hospital mortality rate for to- tal gastrectomy in Maryland, between 1990 and 1997, was 15.5% (range 7.5%–22.9%); these data included al patients resected for all cancer location, at all TNM stages. Considering that, although not specified, recon- struction is usually performed by esophagojejunostomy Roux-en-Y, we could suppose that mucosal esophageal 552 Letters to the Editor J Am Coll Surg
stripping and colon interposition could not only im- prove postoperative nutritional problems, but also post- operative mortality. Most probably, we could state that this very interesting procedure, which is very effective in Dr Saidi’s experience, needs to be more extensively ap- plied by other surgeons in a prospective, multicentric randomized trial to assess its real impact on treatment of advanced proximal gastric cancer.

Reply Farrokh Saidi, MD, FACS Tehran, Iran As Drs Di Lorenzo and associates rightly point out, the Roux-en-Y esophagojejunostomy remains the standard manner of reconstruction after palliative total gastrec- tomy. This is understandable because surgeons are reluc- tant to enlarge the scope of the operation when survival of patients with advanced stomach cancer is short. But some of these posttotalgastrectomy patients live longer than anticipated. And when they become incapacitated by relentless weight loss and severe postprandial distress, the surgeon regrets having removed the stomach in the first place. As a gastric reservoir, the left colon is large enough to allow patients to eat comfortably full course meals, until the inevitable terminal phase of their disease. The ques tion is how to mobilize and use the left colon as a gastri substitute in the least traumatic manner. The endoe- sophageal route is the shortest way for transposing the colon to the neck. This manner of reconstruction after a palliative totalgastrectomy may lower postoperative morbidity because it dispenses with the cumbersome esophagojejunostomy, especially if an attempt is made fashion a jejunal loop. We start jejunal feeding on the first or second postoperative day, and this may lower postoperative morbidity. The manner of reconstruction has, of course, no bearing on length of survival. On the technical side, the likelihood of leaving small strips of esophageal mucosa behind, was worrisome at first.Nothing serious happened, however, even when the esophageal mucosal sleeve did not come out intact one piece. The possibility of strangling the colon seg- ment in the neck loomed more portentous. This fear also proved groundless. We have not observed any ve- nous congestion of the colon once it has reached the neck.The one episode of totalcolon infarction was found to be from thrombosis beginning at the origin of the left colic artery. Transecting both strap muscles in t neck creates plenty of room in the neck. It is essential, also,to manually overcome the diffuse spasm of the esophageal muscle, the moment its mucosal layer has been stripped off. Clearly, as was indicated by Drs Di Lorenzo and associates, the proposed technique of re- construction after total gastrectomy must earn its value in the hands of other surgeons. What happens to the esophageal muscular layer in th long run? We have had the opportunity to inspect this layer at 1 and 5 years after the operation. On both occa sions the esophageal muscular tunnel wrapped around the transposed colon in the posterior mediastinum was nothing more than a thin film of tissue. The endoesophageal colon pull-through technique is no more time consuming than the standard esophage- ojejunostomy. But it must be performed in an unhurried manner and with exactitude. I have regretted at times, halfway through a transhiatal esophagectomy, not hav- ing started off with the endoesophageal pull-through, which can always be converted into the former. 553 Vol. 192, No. 4, April 2001 Letters to the Editor
