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.

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.

We were very interested in the article by Farrokh Saidi
and associates, “A new approach to the palliation of advanced proximal gastric cancer.”1 The original technique
of reconstruction proposed is very interesting for esophageal cancer, and the functional results, as previously
described by Dr Saidi in 1988 and 1991,2 seem to be

and cardia, some considerations should be pointed out.
The authors seem to consider their operation as an

Gastric interposition is usually considered the reconstruction of choice following esophageal resection. However, a number of reports show that esophagectomy followed by a gastric transplant is associated with poor quality of life and significant reflux esophagitis in the esophageal remnant. The aim of this work is to review the factors affecting the mucosa of the esophageal remnant when using the stomach. A Medline was conducted. Additional references and search pathways were sourced from the references of reviewed articles. Reflux disease is considered an unavoidable consequence of esophageal resection followed by gastric interposition. Mucosal damage from acid and bile exposure in the esophageal remnant affects approximatively 50% of these patients. There is usually no correlation between symptoms and the presence of mucosal damage in the remaining esophagus. Endoscopy and endoscopic biopsies are the only reliable methods to document the status of the mucosa. When present, reflux esophagitis shows a progression from inflammation to erosions and to the development of columnar lined metaplasia. Esophageal and gastric function, gastric drainage operation, level of the anastomosis, route of reconstruction, and patients' position after the operation have all been shown to influence the severity and extent of damage in the esophageal remnant. Prevention and treatment of esophagitis in the remaining esophagus are discussed. When the stomach is used as a substitute to reconstruct the esophagus whether for malignant or benign conditions, an in vivo model of reflux diseases is created. Studies using this model may help clarify molecular and cellular events that lead to irreversible insult on the esophageal mucosa. Improvement to the reconstruction itself must be sought to favor better results with the gastric transplant.
Introduction Pancreaticoduodenectomy after transhiatal esophagectomy is a technically demanding procedure in sense of preserving the blood supply to the gastric tube. Case Report We report a case of pylorus-preserving pancreaticoduodenectomy for pancreatic head cancer, 13 years after a transhiatal esophagectomy, sparing the gastric tube and the right gastroepiploic artery and vein. Discussion This type of operation is less time-consuming and less invasive, since no further reconstruction of the alimentary tract or the vascular system is applied.
Aim: To report the initial monocentric experience of totally laparoscopic total gastrectomy, assessing its feasibility and safety, especially relating to the challenging step of esophago-jejunal (E-J) reconstruction.
Methods: All consecutive patients, underwent laparoscopic total gastrectomy for gastric cancer with curative intent, between January 2017 and June 2018 at our institution, were considered. Data of the selected patients was retrieved from a prospectively collected database. Short and long term outcomes were analyzed.
Results: Ten patients underwent totally laparoscopic total gastrectomy with D2 lymphadenectomy and 4 of these had received preoperative chemotherapy; Two patients also received the lymphadenectomy of the station 10. E-J reconstruction consisted of hemi-double stapling technique with transorally inserted anvil in 1 case, side-to-side overlap anastomosis in 5 cases and end-to-side anastomosis in 4 cases. One patient experienced intraoperative complications needing conversion to laparotomy. Seven patients experienced postoperative complications, three of these were severe according to Dindo-Clavien classification. All the specimens had free proximal resection margins with R0 resection in all the cases. Average postoperative length of hospital stay was 10 days and no patients died during hospitalization. Median overall survival and disease-free survival were 15.5 and 12.5 months respectively.
Conclusion: Totally laparoscopic total gastrectomy is a feasible and safe option in the treatment of gastric cancer. The choice about the type of E-J reconstruction should be based on the single patient’s features and on the dexterity of the surgeon who should be able to perform more than one option for a tailored approach.
Bowel reconstruction after subtotal esophagectomy represents a problem when a previous distal gastrectomy was performed: usually the colon or jejunum is used. In a 10 year period 126 patients with primary esophageal cancer underwent esophageal resection in our Department. Surgical procedures were 57% two-phase subtotal oesophagectomy, 23% transhiatal, 9% stripping, 10 three-phase total esophagectomy and 2 endoscopic resections. In 112 patients alimentary tract reconstruction was achieved by means of esophago-gastric anastomosis. Reconstruction was performed using colon in 10 cases and jejunum in 2. We describe the technical aspects of esophagectomy and gastric reconstruction in a patient with previous antrectomy and Billroth II reconstruction. The procedure was performed via a combined laparotomy and thoracotomy with anastomosis at the level of the azygous vein using the remnant stomach. Few technical reports have been reported in literature about the use of remnant stomach in recon...
Controversies exist about feasibility and oncologic effectiveness of laparoscopic gastrectomies with extended lymphadenectomy for advanced gastric cancer. The aim of our study was to determine if long-term results of these laparoscopic procedures may justify their use as an alternative to open surgery also in advanced gastric cancer. We performed a retrospective review of 100 patients after laparoscopic surgery for gastric cancer. Tumor stage (S) was SIA in 21 patients, SIB in 20, SII in 17, SIIIA in 17, SIIIB in 5, and SIV in 20. Eleven total and 89 subtotal R0 gastrectomies were performed. The mean number of dissected lymph nodes was 35 +/- 18. The conversion rate was 3%. Surgical mortality and major morbidity were 6% and 13%, respectively. Overall and disease-free 5-year survival rates were 59% and 57%, respectively. Laparoscopic gastrectomy with extended lymphadenectomy for early and advanced gastric cancer is feasible, safe, and oncologically effective. Long-term survival rates are similar to those observed after open surgery.
Laparoscopic surgery has been used in the treatment of early gastric cancer with low mortality and morbidity and improvement in patient's quality of life. The purpose of the current study was to determine if these advantages persist after radical laparoscopic treatment of more advanced gastric cancer. A retrospective review of 44 patients after laparoscopic surgery for gastric cancer was performed. Tumor stage was IA in 8 patients, IB in 12, II in 9, IIIA in 6, IIIB in 1, and IV in 8. Eight total and 36 subtotal R0 gastrectomies were performed (12 D(1) and 32 D(2)). The mean number of dissected lymph nodes was 38.1 +/- 21.5. Conversion rate was 7%. Operative mortality and morbidity were 7% and 12%, respectively. Three-year survival was 75%. Laparoscopic radical total or subtotal gastrectomy with extended lymphadenectomy for gastric cancer is a feasible, safe, and oncologically effective procedure.

Duodenogastric reflux (DGR) is barely responsive to medications and antireflux fundoplication is not able to control the gastric symptoms. Duodenal switch (DS) preserves the physiologic food transit while creating an effective Roux-en-Y diversion to duodenal juice. However, it never enjoyed great popularity, perhaps due to the invasiveness of the open approach. The paper reports our initial experience with laparoscopic DS. Preoperative assessment, surgical technique, and outcomes are described. Normalization of DGR was demonstrated by preoperative and postoperative 24-hour bilimetry and pH-multichannel intraluminal impedance. The procedure was completed under laparoscopy in all the cases with a mean operative time of 165 minutes. Mean blood loss was 200 mL. No patient required admission to the intensive care unit. Initial experience with laparoscopic DS encourages continued use of the minimally invasive approach. A meticulous preoperative evaluation is essential to place a correct i...
The prognosis of gastroesophageal junction adenocarcinoma is unquestionably related to the extent of nodal involvement; nonetheless, few studies deal with the pattern of lymph node spread and specifically analyze the prognostic value of the site of metastasis. The present study was aimed at evaluating these key aspects in advanced gastroesophageal junction adenocarcinoma. Of 219 patients consecutively operated on for gastroesophageal junction adenocarcinoma at the Department of General Surgery and Surgical Oncology, University of Siena, and at the Department of General Surgery, University of Verona, 143 pT2-4 tumors not submitted to prior chemoradiation were analyzed according to the Japanese Gastric Cancer Association pN staging system. The majority of patients were given diagnoses of nodal metastases (77.6%). The mean number (P = .076) and the percentage of patients with pN+ disease (P = .022) progressively increased from Siewert type I to type III tumors. Abdominal nodes were involved in all but 1 of the patients with pN+ disease; conversely, nodal metastases into the chest were 46.2% for type I, 29.5% for type II, and 9.3% for type III tumors. Survival analysis showed virtually no chance of recovery for patients with more than 6 metastatic nodes or lymph nodes located beyond the first tier. In advanced gastroesophageal junction adenocarcinoma, the high frequency of nodal metastases and the related unfavorable long-term outcome achieved by means of surgical intervention alone are indicative of the need for aggressive multimodal treatment along with surgical intervention to improve long-term results.
Various types of reconstruction have been employed in attempts to improve the quality of life after total gastrectomy. The use of a jejunal pouch has been the most common approach, and preservation of the duodenal passage has been recommended in several related studies. The aim of the present study was to investigate the benefit of the use of a segment of transverse colon as a gastric substitute. Isoperistaltic interposition with a segment of transverse colon was performed after total gastrectomy in 18 patients with gastric malignancies. To clarify the benefits and disadvantages of this technique, a comparison was made between these patients and another 17 patients who underwent jejunal interposition without a pouch. The parameters to be compared included operation time, amount of blood loss, incidence of postoperative complications, and changes in body weight. Postoperative complications were more frequent in the patients reconstructed with the transverse colon, despite a lower inc...
