Open versus laparoscopic gastrectomy for advanced gastric cancer: a propensity score matching analysis of survival in a western population-on behalf of the Italian Research Group for Gastric Cancer.

BACKGROUND: Oncologic outcomes after laparoscopic gastrectomy for advanced gastric cancer in the West have been poorly investigated. The aim of the present study was to compare survival outcomes in patients undergoing curative-intent laparoscopic and open gastrectomy for advanced gastric cancer in several centres belonging to the Italian Research Group for Gastric Cancer. METHODS: Data of patients operated between 2015 and 2018 were retrospectively analysed. Propensity Score Matching was performed to balance baseline characteristics of patients undergoing laparoscopic and open gastrectomy. The primary endpoint was 3-year overall survival. Secondary endpoints were 3-year disease-free survival and short-term outcomes. Multivariable regression analyses for survival were conducted. RESULTS: Data were retrieved from 20 centres. Of the 717 patients included, 438 patients were correctly matched, 219 per group. The 3-year overall survival was 73.6% and 68.7% in the laparoscopic and open group, respectively (p = 0.40). When compared with open gastrectomy, laparoscopic gastrectomy showed comparable 3-year disease-free survival (62.8%, vs 58.9%, p = 0.40), higher rate of return to intended oncologic treatment (56.9% vs 40.2%, p = 0.001), similar 30-day morbidity/mortality. Prognostic factors for survival were ASA Score ≥ 3, age-adjusted Charlson Comorbidity Index ≥ 5, lymph node ratio ≥ 0.15, p/ypTNM Stage III and return to intended oncologic treatment. CONCLUSIONS: Laparoscopic gastrectomy for advanced gastric cancer offers similar rates of survival when compared to open gastrectomy, with higher rates of return to intended oncologic treatment. ASA score, age-adjusted Charlson Comorbidity Index, lymph node ratio, return to intended oncologic treatment and p/ypTNM Stage, but not surgical approach, are prognostic factors for survival.

Patient-reported outcomes after oesophagectomy in the multicentre LASER study.

BACKGROUND: Data on the long-term symptom burden in patients surviving oesophageal cancer surgery are scarce. The aim of this study was to identify the most prevalent symptoms and their interactions with health-related quality of life. METHODS: This was a cross-sectional cohort study of patients who underwent oesophageal cancer surgery in 20 European centres between 2010 and 2016. Patients had to be disease-free for at least 1 year. They were asked to complete a 28-symptom questionnaire at a single time point, at least 1 year after surgery. Principal component analysis was used to assess for clustering and association of symptoms. Risk factors associated with the development of severe symptoms were identified by multivariable logistic regression models. RESULTS: Of 1081 invited patients, 876 (81.0 per cent) responded. Symptoms in the preceding 6 months associated with previous surgery were experienced by 586 patients (66.9 per cent). The most common severe symptoms included reduced energy or activity tolerance (30.7 per cent), feeling of early fullness after eating (30.0 per cent), tiredness (28.7 per cent), and heartburn/acid or bile regurgitation (19.6 per cent). Clustering analysis showed that symptoms clustered into six domains: lethargy, musculoskeletal pain, dumping, lower gastrointestinal symptoms, regurgitation/reflux, and swallowing/conduit problems; the latter two were the most closely associated. Surgical approach, neoadjuvant therapy, patient age, and sex were factors associated with severe symptoms. CONCLUSION: A long-term symptom burden is common after oesophageal cancer surgery.

Randomized clinical trial of psychological support and sleep adjuvant measures for postoperative sleep disturbance in patients undergoing oesophagectomy.

BACKGROUND: Major surgery such as oesophagectomy requires a postoperative stay in intensive care. Painful stimuli lead to sleep disturbance and impairment in quality of life. The aim of this study was to evaluate the effect of psychological counselling and sleep adjuvant measures on postoperative quality of sleep and quality of life. METHODS: This RCT was performed between January 2013 and October 2015. Patients undergoing oesophagectomy for cancer were randomized into one of four groups receiving: psychological counselling plus sleep adjuvant measures during the ICU stay; psychological counselling alone; sleep adjuvant measures alone during the ICU stay; or standard care. The primary endpoint was impairment in quality of life measured using the European Organisation for Research and Treatment of Cancer C30-QL2 questionnaire between admission for surgery and discharge from hospital. The secondary endpoint was impairment in quality of sleep assessed by means of the Pittsburgh Sleep Quality Index between admission for surgery and hospital discharge. RESULTS: The local ethics committee approved the early termination of the study because of relevant changes in the ICU setting. Some 87 patients were randomized and 74 patients were evaluated in the analysis. Psychological counselling reduced the impairment in quality of life (odds ratio 0·23, 95 per cent c.i. 0·09 to 0·61) and in quality of sleep (odds ratio 0·27, 0·10 to 0·73). CONCLUSION: Perioperative psychological support reduces impairment in quality of life and quality of sleep after oesophagectomy. Registration number: NCT01738620 (http://www.clinicaltrials.gov).

A systematic review of segmental vs subtotal colectomy and subtotal colectomy vs total proctocolectomy for colonic Crohn's disease.

AIM: Surgical management of colonic Crohn's disease (CD) is still unclear because different procedures can be adopted. The choice of operation is dependent on the involvement of colonic disease but the advantages and disadvantages of the extent of resection are still debated. METHOD: The aim of the present study was to evaluate the differences in short-term and long-term outcomes of adult patients with colonic CD who underwent either subtotal colectomy and ileorectal anastomosis (STC) or segmental colectomy (SC) or total proctocolectomy and end ileostomy (TPC). Studies published between 1984 and 2012 including comparisons of STC vs SC and of STC vs TPC were selected. The study end-points were overall and surgical recurrence, postoperative morbidity and incidence of permanent stoma. Fixed effect models were used to evaluate the study outcomes. RESULTS: Eleven studies, consisting of a total of 1436 patients (510 STC, 500 SC and 426 TPC), were included. Analysis of the data showed no significant difference between STC and SC in terms of overall and surgical recurrence of CD. In contrast, STC showed a higher risk of overall and surgical recurrence of CD than TPC (OR 3.53, 95% CI 2.45-5.10, P < 0.0001; OR 3.52, 95% CI 2.27-5.44, P < 0.0001, respectively). SC had a higher risk of postoperative complications compared to STC, and STC had a lower risk of complications than TPC (OR 2.84, 95% CI 1.16-6.96, P < 0.02; OR 0.19, 95% CI 0.09-0.38, P < 0.0001, respectively). SC resulted in a lower risk of permanent stoma than STC (OR 0.52, 95% CI 0.35-0.77). CONCLUSION: All three procedures were equally effective as treatment options for colonic CD and the choice of operation remains intrinsically dependent on the extent of colonic disease. However, patients in the TPC group showed a lower recurrence risk than those in the STC group. Moreover, SC had a higher risk of postoperative complications but a lower risk of permanent stoma. These data should be taken into account when deciding surgical strategies and when informing patients about postoperative risks.

Association of autoimmune thyroid diseases, chronic atrophic gastritis and gastric carcinoid: experience from a single institution.

PURPOSE: Autoimmune polyendocrine syndromes (APS) type III are characterized by the association of autoimmune thyroid disease (ATD) with other autoimmune diseases such as diabetes, alopecia, pernicious anemia, vitiligo and chronic atrophic gastritis. A strong association between ATD and atrophic gastritis (AG) has been demonstrated. Moreover 10 % of patients affected by AG have a predisposition to develop gastric carcinoid and adenocarcinoma as a result of chronic hypergastrinemia caused by achlorhydria and subsequent ELC cells neoplastic transformation. METHODS: The aim of the study is to evaluate, in a consecutive series of patients followed for ATD in our outpatients clinic, the prevalence of AG. In the period 2004-2014, 242 patients with ATD underwent a screening performing APCA, Vitamin B12, ferritin, iron, and hemoglobin and red cells count measurements with subsequent gastroscopy in case of APCA positivity. RESULTS: We found 57/242 (23.5 %) patients with APCA positivity. Of these patients 33/57 (57.8 %), 31 F and 2 M, were affected by Graves disease; 24/57 (42.1 %) 21 F and 3 M by Hashimoto thyroiditis; 10/57 (17.5 %) presented with anemia, 14/57 (24.5 %) with vitamin B12 deficiency, 9/57 (15.7 %) with iron deficiency. In 2/57 a gastric carcinoid was found. CONCLUSIONS: Our data confirm the high association rate of AG in ATD which frequently is not an isolated disease but configure the picture of APS type III and need to be followed accordingly. An early diagnosis may be useful for diagnosis of gastric carcinoids and to explain and treat a gastric related L-thyroxine malabsorption and presence of chronic unexplained anemia.

Hybrid minimally invasive esophagectomy for cancer: impact on postoperative inflammatory and nutritional status.

The purpose of this case-control study was to evaluate the impact of hybrid minimally invasive esophagectomy for cancer on surgical stress response and nutritional status. All 34 consecutive patients undergoing hybrid minimally invasive esophagectomy for cancer at our surgical unit between 2008 and 2013 were retrospectively compared with 34 patients undergoing esophagectomy with open gastric tubulization (open), matched for neoadjuvant therapy, pathological stage, gender and age. Demographic data, tumor features and postoperative course (including quality of life and systemic inflammatory and nutritional status) were compared. Postoperative course was similar in terms of complication rate. Length of stay in intensive care unit was shorter in patients undergoing hybrid minimally invasive esophagectomy (P = 0.002). In the first postoperative day, patients undergoing hybrid minimally invasive esophagectomy had lower C-reactive protein levels (P = 0.001) and white cell blood count (P = 0.05), and higher albumin serum level (P = 0.001). In this group, albumin remained higher also at third (P = 0.06) and seventh (P = 0.008) postoperative day, and C-reactive protein resulted lower at third post day (P = 0.04). Hybrid minimally invasive esophagectomy significantly improved the systemic inflammatory and catabolic response to surgical trauma, contributing to a shorter length of stay in intensive care unit.

Impact of esophagectomy for cancer on patients' occupational status.

BACKGROUND: The aim of our study was to investigate the impact of esophagectomy for cancer on patients' occupational status. METHODS: All 109 consecutive patients presenting with esophageal cancer to the Surgical Oncology Unit of the Veneto Institute of Oncology Padua (Italy) between November 1, 2009 and March 15, 2012, were included in the study. Information on occupational status at diagnosis and at 1 year after esophagectomy was retrieved. Health-related quality of life was evaluated at discharge after surgery using selected aspects of the EORTC QLQ-C30 questionnaire. Non parametric statistics were used. RESULTS: Sixty-one patients (49.6%) were active workers at diagnosis and 50 of them (82.0%) underwent esophagectomy. Eighteen active workers (18/50, 36.0%) quit their job within one year from esophagectomy. They received jejunostomy more often than patients still working after surgery (50.0% vs. 18.8%, respectively; p = 0.03) and reported lower social functioning at discharge (mean ± SD 63.6 ± 16.4 vs. 80.2 ± 25.6 in others, p = 0.02). Multivariable analysis identified jejunostomy as independent predictor of job-quitting at 1 year after esophagectomy (p = 0.03; OR 4.75, 95% C.I. 1.11-20.39) but not social functioning at discharge (p = 0.21). CONCLUSIONS: Patients should be informed that they may experience social and work disability due to cancer treatment and adequate interventions of return-to-work support should be provided. Adequate welfare strategy should be implemented for esophageal cancer survivors, enhancing their role competences and contributing to precision care medicine.

Esophagectomy in elderly patients: which is the best prognostic score?

Our study aimed to identify the best prognostic score for fitness for surgery and postoperative morbidity in elderly patients. A prospectively collected database of a consecutive series of patients with esophageal cancer evaluated for possible esophagectomy at our unit was analyzed. Fitness for surgery and postoperative morbidity were used as measures of outcome. The performances of the Physiological and Operative Severity Score for the enUmeration of Mortality and morbidity (POSSUM) score, the Charlson Comorbidity Index, the age-related Charlson Comorbidity Index (ACCI), the American Society of Anesthesiologists scale and the prognostic nutritional index (PNI) were evaluated in elderly patients. Discrimination was measured with receiver operating characteristics curve analysis; calibration was assessed by the Hosmer-Lemeshow goodness-of-fit test. Age did not result a significant predictor for postoperative complications. In elderly patients, ACCI predicted the judgment of the multidisciplinary team about fitness for surgery with the best discrimination (C-index = 0.94). PNI had the best discrimination for postoperative complications (C-index = 0.71) in the elderly group. ACCI best predicted the fitness for surgery in elderly patients. In elderly patients, the most discriminative prognostic score for postoperative complication was PNI, which could be used at admission for surgery to correctly inform patients about their risk and, possibly, to take extra precaution in case of high risk.

Postoperative outcome after oesophagectomy for cancer: Nutritional status is the missing ring in the current prognostic scores.

BACKGROUND: Several prognostic scores were designed in order to estimate the risk of postoperative adverse events. None of them includes a component directly associated to the nutritional status. The aims of the study were the evaluation of performance of risk-adjusted models for early outcomes after oesophagectomy and to develop a score for severe complication prediction with special consideration regarding nutritional status. METHODS: A comparison of POSSUM and Charlson score and their derivates, ASA, Lagarde score and nutritional index (PNI) was performed on 167 patients undergoing oesophagectomy for cancer. A logistic regression model was also estimated to obtain a new prognostic score for severe morbidity prediction. RESULTS: Overall morbidity was 35.3% (59 cases), severe complications (grade III-V of Clavien-Dindo classification) occurred in 20 cases. Discrimination was poor for all the scores. Multivariable analysis identified pulse, connective tissue disease, PNI and potassium as independent predictors of severe morbidity. This model showed good discrimination and calibration. Internal validation using standard bootstrapping techniques confirmed the good performance. CONCLUSIONS: Nutrition could be an independent risk factor for major complications and a nutritional status coefficient could be included in current prognostic scores to improve risk estimation of major postoperative complications after oesophagectomy for cancer.

Complications after surgery for colorectal cancer affect quality of life and surgeon-patient relationship.

AIM: This multicentric prospective study aimed to investigate how postoperative complications after surgery for colorectal cancer affect patients' quality of life and satisfaction with care. METHOD: One hundred and sixteen patients operated on for colorectal cancer were enrolled in this study. Patients answered three questionnaires about generic (EORTC QLQ-C30) and disease-specific (EORTC QLQ-CR29) quality of life and treatment satisfaction (EORTC IN-PATSAT32) at the time of admission and at 1 and 6 months after surgery. Non-parametric tests and linear multiple regression models were used for statistical analysis. RESULTS: Twelve patients had complications requiring further surgery (anastomotic leakage, abdominal bleeding, abdominal wall sepsis, wound infection). Patients with complications that required surgery reported a worse score of physical function, emotional function and anxiety than patients without such complications 1 month after surgery. These patients judged their general satisfaction with the quality of care and doctors' interpersonal skills, technical skills, information provision and availability to be worse than in patients without such complications. The presence of postoperative psychiatric complications and anastomotic leakage were independent predictors of quality of life (ß = -0.30, P = 0.004, and ß = -0.42, P < 0.001). CONCLUSION: In patients undergoing surgery for colorectal cancer, complications requiring any kind of surgical management significantly affected patients' perception of all doctor-related items suggesting an impairment of the entire surgeon-patient relationship. Convincing patients that 'zero risk' cannot be achieved in surgical practice is therefore a priority.

Effect of preoperative chemoradiotherapy on outcome of patients with locally advanced esophagogastric junction adenocarcinoma-a pilot study.

BACKGROUND: To date, few studies of preoperative chemotherapy or chemoradiotherapy (crt) in gastroesophageal junction (gej) cancer have been statistically powered; indeed, gej tumours have thus far been grouped with esophageal or gastric cancer in phase iii trials, thereby generating conflicting results. METHODS: We studied 41 patients affected by locally advanced Siewert type i and ii gej adenocarcinoma who were treated with a neoadjuvant crt regimen [folfox4 (leucovorin-5-fluorouracil-oxaliplatin) for 4 cycles, and concurrent computed tomography-based three-dimensional conformal radiotherapy delivered using 5 daily fractions of 1.8 Gy per week for a total dose of 45 Gy], followed by surgery. Completeness of tumour resection (performed approximately 6 weeks after completion of crt), clinical and pathologic response rates, and safety and outcome of the treatment were the main endpoints of the study. RESULTS: All 41 patients completed preoperative treatment. Combined therapy was well tolerated, with no treatment-related deaths. Dose reduction was necessary in 8 patients (19.5%). After crt, 78% of the patients showed a partial clinical response, 17% were stable, and 5% experienced disease progression. Pathology examination of surgical specimens demonstrated a 10% complete response rate. The median and mean survival times were 26 and 36 months respectively (95% confidence interval: 14 to 37 months and 30 to 41 months respectively). On multivariate analysis, TNM staging and clinical response were demonstrated to be the only independent variables related to long-term survival. CONCLUSIONS: In our experience, preoperative chemoradiotherapy with folfox4 is feasible in locally advanced gej adenocarcinoma, but shows mild efficacy, as suggested by the low rate of pathologic complete response.

First-line chemotherapy improves the resection rate and long-term survival of locally advanced (T4, any N, M0) squamous cell carcinoma of the thoracic esophagus: final report on 163 consecutive patients with 5-year follow-up.

OBJECTIVE: The objective of this prospective, nonrandomized study was to evaluate the immediate and long-term results of first-line chemotherapy and possible surgery in locally advanced, presumably T4 squamous cell esophageal cancer. SUMMARY BACKGROUND DATA: Locally advanced esophageal cancer is rarely operable and has a dismal prognosis. For this reason, neoadjuvant cytoreductive treatments are more and more frequently used with the aim of downstaging the tumor, increasing the resection rate, and possibly improving survival. METHODS: From January 1983 to December 1991, 163 consecutive patients with a presumedly T4 squamous cell carcinoma of the thoracic esophagus (group A) received on average 2.5 cycles (range, 1-6) of first-line chemotherapy with cisplatin (100 mg/m2 on day 1) and 5-fluorouracil (1000 mg/m2 per day, in continuous infusion from day 1 through day 5). Chemotherapy was followed by surgery when adequate downstaging of the tumor was obtained. RESULTS: Chemotherapy toxicity was WHO grade 0 to 2 in 80% of cases, but 3 toxic deaths (1.9%) occurred. Restaging suggested a downstaging of the tumor in 101 of 163 patients (62%), but only 85 patients (52%) underwent resection surgery; it was complete or R0 in 52 (32%) and incomplete or R1-2 in 33. Overall postoperative mortality was 11.7% (10 of 85), morbidity 41% (35 of 85). Complete pathologic response was documented in 6 patients, and significant downstaging to pStage I, IIA, or IIB occurred in 25 more patients. The overall 5-year survival was 11 % (median, 11 months). After resection surgery, the 5-year survival was 20% (median, 16 months); none of the nonresponders survived 4 years after palliative treatments without resection (median survival, 5 months). The 5-year survival rate of the 52 patients undergoing an R0 resection was 29% (median, 23 months). Stratifying patients according to the R, pT, pN, and pStage classifications, the survival curves were comparable to the corresponding data obtained in the 587 group B patients with "potentially resectable" esophageal cancer who underwent surgery alone during the same period. Furthermore, the results were improved in comparison with 136 previous or subsequent patients with a locally advanced tumor who did not undergo neoadjuvant treatments (group C). In these patients, the R0 resection rate was 7%, and the overall 5-year survival was 3% (median, 5 months). CONCLUSION: Although nonrandomized, these results suggest that in locally advanced esophageal carcinoma, first-line chemotherapy increases the resection rate and improves the overall long-term survival. In responding patients who undergo R0 resection surgery, the prognosis depends on the final pathologic stage and not on the initial pretreatment stage.

[Prosthetic bilateral laparoscopic hernioplasty. Extra-peritoneal approach]. / Ernioplastica laparoscopica bilaterale protesica. Accesso pre-peritoneale.

The use of prosthetic mesh in inguinal hernia repairs is becoming increasingly popular. In recent years different laparoscopic procedures for prosthetic repair of inguinal hernias have been developed. The authors describe their initial experience with a totally extra-peritoneal prosthetic approach in laparoscopic repair of bilateral inguinal hernias. From November 1993 to May 1994, ten consecutive patients with bilateral primary inguinal hernias underwent laparoscopic repair under general anesthesia. A totally extra-peritoneal approach has been performed beginning through a 2 centimeter vertical midline sub-umbilical incision. Two additional trocars have been inserted on the midline: a 10/12 mm one halfway between the umbilicus and the pubis and 5 mm one 2 cm above the pubis. Average operative time was 141 minutes. Two cases were converted to traditional open Stoppa procedure because of holes made in the peritoneum during blunt dissection of the hernia sac. In the remaining 8 cases a polypropylene mesh of about 8 cm in height and 13 cm in length have been placed on each hernia site. No major complications have been observed and recovery was quick in all cases. In conclusion we think that laparoscopic hernia repair through a totally extra-peritoneal approach is technically feasible for general surgeons trained in laparoscopic surgery. Nevertheless the operation in costly and the patient's benefit in terms of rapid recovery, complications and recurrences has not yet been demonstrated in controlled prospective trials.

Mediastinal cyst involving the oesophagus: diagnosis and results of surgical treatment.

OBJECTIVE: To describe our experience with mediastinal cysts involving the oesophagus. DESIGN: Retrospective study. SETTING: University hospital, Italy. SUBJECTS: 11 patients who presented to our department with a mediastinal cyst from 1976-1994. INTERVENTIONS: Excision of the mass through a posterolateral thoracotomy (n = 10) or by video-assisted thoracoscopy. MAIN OUTCOME MEASURES: Morbidity and mortality. RESULTS: 8 patients presented with retrosternal or epigastric pain, three of whom had mild dysphagia. In the remaining 3 the tumour was asymptomatic and an incidental finding on a chest radiograph. Endoscopic ultrasonography and computed tomography (CT) allowed preoperative diagnosis of an extramucosal cyst in 5 of the 7 patients investigated by both tests. Masses were excised through a formal thoracotomy (n = 10) or by video-assisted thoracoscopy. Histological examination confirmed a benign cyst in all cases. There was no operative morbidity and nine patients are free of symptoms after a median follow-up of 2.3 years. CONCLUSION: Excision, preferably by thoracoscopy, is the treatment of choice for mediastinal cysts that involve the oesophagus. Special attention should be paid to the vagal nerves, and as many as possible of the muscular layers of the oesophagus should be preserved.

Outpatient surgery of varices of the lower limbs: experience of 2,568 cases at four universities.

Outpatient surgery of varices of the lower limbs is currently considered a viable alternative to traditional surgery with hospitalization. This paper reports the experience of 4 university groups (Padua, Modena, Verona, Milan), where outpatient treatment has been used since 1987. From June 1987 to June 1992, 2,568 lower limb varices were treated in this way. Different techniques of anaesthesia were used (local infiltration, combined local and general, general, subarachnoid). In all cases, crossectomy was combined with short or long saphenous stripping. There were no intra- or perioperative deaths, and only limited morbidity. Postoperative hospitalization was required in only 2 cases: for hemorrhaging of the inguinal wound in one case, and headache 2 days after spinal anaesthesia in the other. In 2 separate samples of 100 patients, 88 and 89 indicated satisfaction with the surgical treatment. In conclusion, outpatient surgery of varices can be based on the same techniques as in-patients treatment. The risks of surgery and anaesthesia in specialised centres are very limited, with scope for a variety of anaesthetic techniques according to facilities available. Patients satisfaction is high.

[Echo-sclerotherapy in the management of varices of the lower extremities]. / La sclerosi ecoguidata nel trattamento delle varici degli arti inferiori.

Sclerotherapy has been used with satisfactory results, for several years in the treatment of varicose veins. Nevertheless sometimes sclerosis can be incomplete because of the morphology of lower limbs or because the varicose disease is not clinically evident. In addition, sclerotherapy can give rise to severe complications due to intrarterial or extraluminal injections. In order to exceed this limits, some authors suggested to use a new technique, the echosclerotherapy, which was presented for the first time in Strasburg 1989 by Knight and Vin. Echosclerotherapy is a good help for traditional sclerotherapy, especially when it is applied in the sclerosis of the short saphenous veins, of perforating veins or in unfavourable anatomical situations. From May to November 1993 at the Second Surgical Department of Padua University, 31 patients, 29 women and 3 men, have been treated by echosclerotherapy. 25 patients had great saphenous varicose veins; 3 patients had varices due to perforating veins of the popliteal fossa and 3 patients varices due to Hunter perforating veins. In 48.4% of cases we obtained a complete sclerosis of the vessel; in 38.7% a stump remained near the sapheno-femoral junction of about two centimeters; in one case the treatment was not completed and in one case remained a stump of ten centimeters. Only in two cases Echosclerotherapy was not able to obtain sclerosis. None of the patients had major complications and nobody had deep vein thrombosis. If we consider our results altogether we can say that in 87% of cases we had good results.(ABSTRACT TRUNCATED AT 250 WORDS)

Single-layered cervical esophageal anastomoses: a prospective study of two suturing techniques.

We carried out a prospective, randomized study over a 1-year period to compare the efficacy of a single layer of continuous absorbable monofilament (Maxon) with that of a single layer of interrupted Polyglactin sutures (Vicryl) in the performance of cervical esophagogastric anastomoses. Forty-two consecutive patients with carcinoma of the esophagus or cardia, in whom the stomach was transposed through the mediastinal route after esophagectomy, were enrolled in the study. There were 21 patients in each group. There was no hospital mortality. One asymptomatic anastomotic leak and two early anastomotic strictures requiring dilation occurred in patients in whom an interrupted technique was employed. The continuous technique required significantly less operative time (p < 0.0001), and the cost of the suture material was reduced markedly. We conclude that either a continuous or an interrupted monolayer esophagogastric anastomosis can give satisfactory results after esophagectomy for cancer, provided that the vascular supply to the gastric fundus is maintained adequately. The continuous technique has the advantages of being time-saving, cheaper, and easier to perform and to teach.
