Effect of laparoscopic esophagomyotomy on chest pain associated with achalasia and prediction of therapeutic outcomes
ABSTRACT The effect of myotomy for achalasia on chest pain has not been clarified. The current study aimed to investigate the therapeutic effect of laparoscopic myotomy on chest pain associated with achalasia and to identify prognostic factors for outcomes.
Between March 2005 and September 2008, 95 patients were available for detailed interviews and for assessment of clearance by timed barium esophagogram (TBE) before and after surgery. Of the 95 patients, 47 (24 men; mean age, 42.9 ± 13.5 years) who experienced chest pain before surgery were studied. The subjects were asked in detail about dysphagia and chest pain before surgery and 6 months after surgery. The frequency and severity of the symptoms were graded on a scale of 0 to 4. In addition, the values obtained by multiplying the grade for frequency by the grades for severity of the two symptoms were defined as the dysphagia score and the chest pain score, respectively. The patients with chest pain scores of 0 after surgery were defined as group A and those with scores smaller than their preoperative scores as group B. The remaining patients with other scores were defined as group C. The background factors and clinical conditions of the three groups were compared.
The mean chest pain score decreased from 5.0 ± 3.2 to 1.0 ± 1.6 (p < 0.001). The score after surgery was 0 for 27 patients and showed a decrease for 15 patients. Although the three groups did not differ in their characteristics, differences were noted in postoperative TBE factors (i.e., groups A and B had significantly shorter barium columns than group C at 1 and 5 min after surgery (p = 0.001).
Laparoscopic myotomy had a therapeutic effect on chest pain associated with achalasia, and improvement in postoperative esophageal clearance may influence the therapeutic effect.

ABSTRACT: Abstract Short gastric vessel division (SGVD) has been performed as a part of fundoplication for achalasia. However, whether or not SGVD is necessary is still unknown. Forty-six patients with achalasia who underwent a laparoscopic surgery with or without SGVD were analyzed. A questionnaire was administered to assess the postoperative improvement. Regarding improvement of dysphagia and postoperative reflux, there were no significant differences between SGVD (+) group and SGVD (-) group (P = 0.588 and P = 0.686, respectively). Nineteen patients (95%) in the SGVD (+) group and 24 (92%) in the SGVD (-) group answered that the surgery was satisfactory (P = 0.756). In the SGVD (+) group, the pre- and postsurgical body weight increase was +7.3%. In the SGVD (-) group, it was 8.2%. There was no significant difference of body weight increase between the 2 groups (P = 0.354). SGVD is not always required in laparoscopic surgery for achalasia.International surgery 11/2014; 99(6):846-50. DOI:10.9738/INTSURG-D-13-00177.1 · 0.25 Impact Factor

ABSTRACT: Purpose To clarify the feasibility and utility of reduced port surgery (RPS) for achalasia. Methods Between September 2005 and June 2013, 359 patients with esophageal achalasia, excluding cases of reoperation, underwent laparoscopic Heller myotomy and Dor fundoplication (LHD) according to our clinical pathway. Three-hundred and twenty-seven patients underwent LHD with five incisions (conventional approach), while the other 32 patients underwent RPS, including eight via SILS. The clinical data were collected in a prospective fashion and retrospectively reviewed. We selected 24 patients matched for gender, age and morphologic type with patients in the RPS group from among the 327 patients (C group). The surgical outcomes were compared between the C and RPS groups. Results There were no significant differences between the two groups in the duration of symptoms, dysphagia score, chest pain score, shape of the distal esophagus and esophageal clearance. The operative time was significantly longer in the RPS group than in the C group (p p Conclusions The surgical outcomes of RPS for achalasia are comparable to those obtained with the conventional method.Surgery Today 01/2015; DOI:10.1007/s00595-014-1109-8 · 1.21 Impact Factor

ABSTRACT: Laparoscopic Heller myotomy (LHM) has supplanted an open approach due to decreased operative morbidity. Our goal was to quantify the incidence of peri-operative complications and identify risk factors for adverse outcomes in LHM. All LHM were queried from 2005 to 2011 from the National Surgical Quality Improvement Program database. Adverse outcomes were identified, and univariate and stepwise logistic regression (MVR) was then performed to quantify association. There were 1,237 LHM in the study period. Patient averages were: age 51.9 ± 16.8 years, BMI 27.3 ± 6.6 kg/m(2), Charlson comorbidity index (CCI) 0.2 ± 0.6. 15.3 % had >10 % body mass loss in the preoperative 6 months. During surgery, 10.2 % underwent concomitant EGD, and mean operative time was 141.6 ± 63.4 min. There were 7(0.06 %) wound complications, 22(1.8 %) general complications, and 30(2.4 %) major complications. Average length of stay (LOS) was 2.8 ± 5.5 days. The rate of readmission and reoperation were 3.1 and 2.3 %, respectively, and there were 4(0.03 %) deaths. General and major complications were associated with alcohol use, pack-years of smoking, weight loss, history of stroke, radiation therapy, and longer operative times (p < 0.05); however, these factors did not remain significant on MVR (p > 0.05). Operative time was found to be significantly longer by 35.3 min for inpatients, 43.1 min in functionally dependent patients, 50.0 min in preoperative septic patients, and 17.2 min with concomitant EGD (p < 0.01 for all). LOS was found to be longer by 1.9 days for inpatients, 1.8 days in ASA category ≥3, and 1.2 days per one point increase in CCI (p < 0.001 for all). LHM is being performed nationally with a low incidence of operative complications and mortality. General and major complications following LHM are associated with patient alcohol use, pack-years of smoking, weight loss, history of stroke, radiation therapy, and longer operative times. Additionally, independent predictors of longer operative time and LOS were identified.Surgical Endoscopy 01/2015; DOI:10.1007/s00464-014-4054-0 · 3.31 Impact Factor
