We faced many of the aforementionedcomplications with nasogastric tubes and thus institutedthe use of retrograde gastrostomy decompression tubesafter esophagectomy in our patients several years ago. Tostudy the impact of retrograde gastrostomy drainage, thisretrospective review was performed.

Patients and Methods

We performed a review of all patients undergoing esoph-agectomy at our institution between January 2000 andDecember 2008. Patient data were abstracted from aprospectively maintained institutional database and in-dividual chart review carried out for missing data. Alloperative records were individually reviewed.

The RG tube was threaded into theconduit in retrograde fashion by a double purse-stringsuture on the antimesenteric wall of a proximal jejunalloop approximately 15 to 20 cm from the ligament ofTreitz (Figs 1–3). A jejunal feeding tube was placed intothe same loop about 5 cm distal to the RG tube. Tubeposition was confirmed on postoperative X-rays (Fig 4).

Both tubes were brought out through the anteriorabdominal wall and secured in place. Our technique issimilar to that described by Urschel and colleagues [4].Nasogastric or RG tubes were maintained on lowcontinuous suction. When decompression was no lon-ger needed, NG tubes were removed and RG tubeswere capped and removed prior to discharge.

Statistical AnalysisContinuous data were summarized by the mean �standard deviation or median (interquartile range),and comparisons between the 2 groups were madewith unpaired Student t tests for means of normallydistributed continuous variables and Wilcoxon ranksum tests for skewed data. Categoric variables weresummarized by frequency with percentage, and �2 orFisher exact tests were used to compare categoric databetween groups. To determine the predictors of post-operative pneumonia and dysrhythmia, binary logisticregression models were utilized for each dependentvariable of interest. Multivariate models were con-structed by purposeful selection of covariates to in-clude variables with p values less than 0.20 in thebivariate analysis. All data analyses were done usingSPSS (SPSS 13.0 for Windows; SPSS Inc, Chicago, IL).A p value less than 0.05 was considered statisticallyignificant.

Results

Between January 2000 and December 2008, 306 patientsunderwent esophagectomy with reconstruction. Of these,54 [17.6%] were female and the mean age of patients was60.8 (range 26 to 88) years. The majority of operationswere performed for cancer. One hundred forty nine of306 (48.7%) patients underwent transhiatal esophagec-tomy while 157 (51.3%) patients underwent Ivor-Lewis orMcKeown three-stage esophagectomy. One hundredninety three of 306 (63%) patients underwent NG tubeplacement while 113 of 306 (37%) had RG insertion. Thegroups were similar in age, gender, history of priorthoracic surgery, smoking status, and indication for sur-gery. Patients in the NG group were more likely to havereceived neoadjuvant chemotherapy or neoadjuvant ra-diation therapy (Table 1). Additionally, patients in theNG group underwent thoracotomy more frequently thanthose in the RG group.

The incidence of respiratory complications was sig-nificantly lower among patients receiving RG for con-duit decompression. Retrograde gastrostomy was as-sociated with lower risk of pneumonia (8% vs 25.9%,p � 0.001), respiratory failure requiring bronchoscopyor reintubation (10.6% vs 23.8%, p � 0.004), and aspi-ration (3.5% vs 10.4%, p � 0.05). Additionally, theincidence of cardiac dysrhythmias was significantlylower in the RG group (15.9% vs 35.8%, p � 0.001)(Table 2). Atrial fibrillation and supraventricular tachy-cardia comprised the majority of dysrhythmias. Theincidence of stroke, chylothorax, conduit necrosis, em-pyema, hemorrhage, pulmonary embolism, wound de-hiscence, wound infection, and myocardial infarctionwere similar between the 2 groups (Table 2). Therewere 4 minor and no major complications related to RGtube placement. One patient developed a skin-levelwound infection requiring bedside debridement andoral antibiotics. Two patients presented with brokentubes at the level of the skin or the jejunum andunderwent endoscopy for tube retrieval. In 1 patient,the RG tube was inadvertently caught in the end-to-end stapled anastomosis between the esophageal rem-nant and the stomach conduit. This required partialopening of the stapled anastomosis and closure withhand-suturing. Anecdotally, several patients who un-derwent NG tube placement inadvertently pulled outtheir tubes and required repositioning with or withoutfluoroscopic-endoscopic guidance. The exact incidenceof this complication was not recorded.

A logistic regression multivariate analysis was per-formed using postoperative pneumonia and dysrhyth-mias as dependent variables. Presence of an NG tube,prior thoracic surgery, history of tobacco use, and useof a thoracotomy incision were predictors of postoper-ative pneumonia. Among these, the presence of an NG

Comment

Reconstruction after esophagectomy commonly utilizes agastric tube or the colon as conduit. In the early postop-erative period, it is imperative to maintain effectivedecompression of the conduit. Preventing conduit dis-tention helps avoid aspiration of gastrointestinal contentsfrom a dilated, fluid-filled conduit. Conduit distentioncan lead to venous congestion and eventual ischemia,while aspiration can result in postoperative respiratorycomplications.

Nasogastric tubes (16-18 Fr) are generally placed intra-operatively and maintained for varying periods of time inthe postoperative period. Commonly, the tubes are keptin position from 3 to 8 days depending upon surgeonpreference and postoperative radiologic evaluation ofconduit emptying and anastomotic integrity. Nasogastrictubes predispose to respiratory complications includingaspiration, pneumonia, sinusitis, pharyngitis, and laryn-gitis, particularly in patients who have recently under-gone a major operation [5]. Other complications associ-

ted with NG tubes include nasal alar necrosis, hollowiscus perforation, gastrointestinal bleeding, inadvertentracheal intubation, and accidental removal of the tube.his last complication, after an esophagectomy, oftenecessitates replacement of the NG tube, either blindlyr under fluoroscopic or endoscopic guidance. Althoughhe incidence of unintentional tube removal is hard tostablish, occurrence is common enough that some sur-eons routinely use nasal stitches or nasal cartilageridles for NG tube retention.An alternative mode of conduit decompression after

sophagectomy has been suggested by Schuchert andolleagues [6], whereby a pharyngostomy is created toass a tube into the gastric or colonic conduit. However,

his procedure puts the hypoglossal nerve, the glosso-haryngeal nerve, and the lowest branch of the facialerve at risk. Other complications associated with thispproach include tract infection, neck cellulitis, inef-ective drainage, and bleeding. Additionally, antegradeube positioning is more effective with use of suction,

herefore both NG and pharyngostomy tubes are sig-

nificantly more effective with wall suction than withgravity drainage [2].

We investigated the use of retrograde gastrostomytubes for conduit decompression after esophagectomy.Similar decompressive techniques have been used bysurgeons in the past. The RG tube is a soft silastic tube122 cm in length and has a sump port built in, similarto a routine NG tube. The tube is secured to theabdominal wall with simple stitches like routine ab-dominal drains. Not only does the tube drain bygravity and (or) suction, it also stents the pylorus, thusencouraging antegrade flow of gastric secretions. Ad-ditionally, spontaneous gastric emptying can be eval-uated by simply capping the tube.

Our data show a clear advantage for the use of retro-grade gastrostomy over conventional NG drainage afteresophagectomy. The presence of an NG tube was thestrongest of 4 significant risk factors for postoperativerespiratory complications. Nasogastric tubes have beenimplicated in colonization of the upper airways withgastrointestinal flora which secondarily cause pneumo-nia [7]. Also, the presence of an NG tube hamperseffective coughing and compromises pulmonary toilet [8].

ooled upper aerodigestive secretions can easily contam-nate the tracheobronchial tree.

We also noted a lower incidence of cardiac arrhythmiasith the use of RG tubes. Common etiologies of postoper-

tive arrhythmias after esophagectomy include catechol-mine release, hypoxemia, or acidosis [7]. These perturba-ions often accompany inflammation or infection; thus, theowered incidence of pneumonia among patients receivingetrograde decompression may explain the reduced rate ofrrhythmia. No specific protocol was in place for prophy-actic measures against postesophagectomy arrhythmiasuring the study period.The insertion of a retrograde drainage tube adds

bout 15 minutes to the duration of an esophagectomy.he initial learning curve involves the ability to guide

he retrograde tube around the C-loop of the duode-um and beyond the pylorus into the conduit. We

ound that the tube is easier to manipulate into theonduit if the pyloric drainage procedure (pyloroplasty-yloromyotomy) has already been performed. We no-

ticed 4 minor complications during the course of thisretrospective study. Two patients had tubes that brokeat the level of the intestinal insertion site and thus
