Systemic inflammation score as a predictor of death within one year after esophagectomy.

BACKGROUND: After radical resection for esophageal cancer, death within 1 year of surgery can occur due both to recurrence and to other diseases, even after postoperative complications have been overcome. This study identified risk factors for early death within 1 year of esophagectomy for reasons other than death in hospital in patients undergoing esophagectomy for esophageal cancer or esophagogastric junction cancer. METHODS: We reviewed 366 patients who underwent esophagectomy without adjuvant treatment between January 2009 and July 2022 for thoracic esophageal cancer or esophagogastric junction cancer. Patients who died within 1 year excluding in-hospital death were compared with those who did not. Multivariable logistic regression analysis was used to identify predictors of death within 1 year after surgery. RESULTS: Death within 1 year occurred in 32 of 366 patients, 24 from primary disease and 8 from other diseases. Deaths within 1 year were significantly older than the other cases, had significantly lower % vital capacity (%VC), and occurred significantly more often in cases in advanced stages of disease. In a multivariable analysis, a systemic inflammation score (SIS) based on serum albumin level and lymphocyte-to-monocyte ratio was identified as an independent predictor of death within 1 year. As SIS increased, %VC decreased significantly, and CRP level and neutrophil-lymphocyte ratio increased significantly. There was no relationship between SIS and pN. Death within 1 year increased as SIS increased (p = 0.001 for trend). CONCLUSION: SIS assessment undertaken before beginning esophageal cancer treatment is a useful predictor of death within 1 year of surgery.

The impact of the American Society of Anesthesiology-Physical Status classification system on the treatment and prognosis of patients with esophageal cancer undergoing esophagectomy.

BACKGROUND: The American Society of Anesthesiologists-Physical Status (ASA-PS) classification system has been shown to predict morbidity and mortality after surgery. However, the impact of the ASA-PS on esophageal cancer treatment remains unclear. This study examined both the impact of the ASA-PS on treatment, including surgery and perioperative chemotherapy, and the prognostic effects of ASA-PS class in patients who had undergone esophagectomy for thoracic esophageal cancer or esophagogastric junction cancer. METHODS: ASA-PS status was collected for 301 patients who had undergone esophagectomy between January 2007 and June 2016 for thoracic esophageal cancer or esophagogastric junction cancer at a single institution. As the ASA-PS was updated in 2014, the previous classifications of all patients were reevaluated using the updated standard by a surgeon with the previous classifications masked. The dose intensity of preoperative chemotherapy was also compared across classes. Multivariate Cox regression analysis was used to analyze the association between ASA-PS class and overall survival. RESULTS: Patients whose reevaluations had placed them in a more severe ASA-PS class showed significantly poorer overall and cancer-specific survival rates. The dose intensities of cisplatin and 5-fluorouracil for preoperative chemotherapy were significantly lower in patients in the more severe ASA-PS classes. Multivariate analysis showed that ASA-PS class was an independent prognostic factor for overall survival. CONCLUSION: Preoperative ASA-PS classification may influence the intensity of perioperative treatment and may be a valuable long-term prognostic factor for patients with esophageal cancer undergoing esophagectomy.

Relationship between the serum cancer antigen 125 level and the weight of surgically enucleated adenomyosis.

Elevated serum levels of cancer antigen 125 (CA125) are known to occur in adenomyosis. However, the relationship between the severity of adenomyosis and serum CA125 levels has not yet been elucidated. The present study aimed to examine the correlation between the weight of adenomyosis and the serum CA125 level. This retrospective study, after applying exclusion criteria, investigated 308 patients who underwent conservative surgery for adenomyosis. Serum CA125 levels were measured before surgery and weights of surgically enucleated adenomyosis were measured in the operating room. Both serum CA125 and surgically enucleated adenomyosis weight showed log-normal distributions. Pearson's product-moment correlation coefficient for the logarithmically converted values was 0.617 (95% confidence interval, 0.54-0.68).The serum CA125 level correlated positively with the weight of adenomyosis. Although the qualitative characteristics and clinical significance of adenomyosis lesions remain unclear, it seems that the investigation of the relative relationship between the serum CA125 level and the size of the affected lesion is useful to observe one of the qualitative features of adenomyosis. Furthermore, the present study supports the use of postoperative serum CA125 levels as an important indicator for determining the therapeutic effects of conservative surgical treatment for adenomyosis and detecting early signs of recurrence. Impact StatementWhat is already known on this subject? Elevated serum cancer antigen 125 (CA125) levels are known to occur in adenomyosis and are widely recognised as helpful in the diagnosis of adenomyosis.What do the results of this study add? There is a positive correlation between the serum CA125 level and the weight of adenomyosis.What are the implications of these findings for clinical practice and/or further research? The postoperative serum CA125 level is an important indicator for evaluating the extent of the affected lesion remaining after conservative surgical treatment for adenomyosis and also helpful for detecting early signs of recurrence. Further study is required to examine whether it is possible to clarify the qualitative characteristics of adenomyosis in each different case based on the CA125-producing ability of the lesion.

Comparison of short-term outcomes between transthoracic and robot-assisted transmediastinal radical surgery for esophageal cancer: a prospective study.

BACKGROUND: The present study aimed to assess the lower invasiveness of robot-assisted transmediastinal radical esophagectomy by prospectively comparing this procedure with transthoracic esophagectomy in terms of perioperative outcomes, serum cytokine levels, and respiratory function after surgery for esophageal cancer. METHODS: Patients who underwent a robot-assisted transmediastinal esophagectomy or transthoracic esophagectomy between April 2015 and March 2017 were included. The perioperative outcomes, preoperative and postoperative serum IL-6, IL-8, and IL-10 levels, and respiratory function measured preoperatively and at 6 months postoperatively were compared in patients with a robot-assisted transmediastinal esophagectomy and those with a transthoracic esophagectomy. RESULTS: Sixty patients with esophageal cancer were enrolled. The transmediastinal esophagectomy group had a significantly lower incidence of postoperative pneumonia (p = 0.002) and a significantly shorter postoperative hospital stay (p < 0.0002). The serum IL-6 levels on postoperative days 1, 3, 5, and 7 were significantly lower in the transmediastinal esophagectomy group (p = 0.005, 0.0007, 0.022, 0.020, respectively). In the latter group, the serum IL-8 level was significantly lower immediately after surgery and on postoperative day 1 (p = 0.003, 0.001, respectively) while the serum IL-10 level was significantly lower immediately after surgery (p = 0.041). The reduction in vital capacity, percent vital capacity, forced vital capacity, and forced expiratory volume at 1.0 s 6 months after surgery was significantly greater in the transthoracic esophagectomy group (p < 0.0001 for all four measurements). CONCLUSIONS: Although further, large-scale studies are needed to confirm our findings, robot-assisted transmediastinal esophagectomy may confer short-term benefits in radical surgery for esophageal cancer. TRIAL REGISTRATION: This trial was registered in the UMIN Clinical Trial Registry ( UMIN000017565 14/05/2015).

Preoperative skeletal muscle index and visceral-to-subcutaneous fat area ratio are associated with long-term outcomes of elderly gastric cancer patients after gastrectomy.

PURPOSE: Sarcopenia is a risk factor of severe surgical complications, short-term outcomes, and long-term outcomes for patients with gastric cancer. Several computed tomography (CT) measurements have been performed to diagnose sarcopenia. However, the optimal CT measurements for determining long-term outcomes have not been revealed. METHODS: A retrospective review of gastric cancer patients with clinical stage I, II, or III who underwent gastrectomy at age 75 years or more at Shizuoka General Hospital from 2007 to 2015 was performed. Using preoperative CT, skeletal muscle index (SMI), total psoas area, intramuscular adipose tissue content in multifidus muscle, morphologic change of psoas muscle, and visceral-to-subcutaneous adipose tissue area ratio (VSR) were measured in the third lumbar section. A Cox regression analysis was used to explore prognostic factors for overall survival. RESULTS: A total of 257 patients were reviewed. There were 171, 53, and 33 patients with clinical stages I, II, and III, respectively. A multivariate analysis indicated that, in addition to age, performance status, clinical stage, and types of resection, which are known prognostic factors, SMI and VSR are prognostic factors (p = 0.016, 0.046, respectively). The prognostic score, which was the frequency of positive SMI and VSR values within the cutoff, also indicates overall survival. The five-year OS rates of patients with prognostic scores of 0, 1, and 2 were 90.9%, 62.3%, and 52%, respectively (p < 0.001). CONCLUSION: Preoperative SMI and VSR were prognostic factors for the overall survival of elderly patients with gastric cancer after gastrectomy.

Hand-assisted robotic surgery in the abdominal phase of robot-assisted oesophagectomy.

Robot-assisted minimally invasive oesophagectomy (RAMIE) has been developed to overcome the technical limitations of conventional thoracoscopic oesophagectomy. Hand-assisted laparoscopic surgery (HALS) is used as a practical and useful technique during the abdominal phase of thoracoscopic oesophagectomy. During RAMIE, a robotic vessel sealer cannot be used with HALS; another vessel sealer or ultrasonic coagulating device for laparoscopic surgery is required. We report an initial experiment using hand-assisted robotic surgery (HARS) for abdominal manipulation during RAMIE as a novel method. Under the pneumoperitoneum induced by insufflating the abdomen to 10 mmHg with carbon dioxide, the assistant surgeon lifted the stomach and greater omentum using the left hand through a 7 cm upper abdominal midline incision at approximately 2 cm below the xiphoid. Subsequently, gastric mobilisation was performed by robot-assisted surgery. Between January 2019 and February 2020, eight patients with thoracic oesophageal cancer underwent RAMIE with HARS at our hospital. The median operative time for extracorporeal manipulation and preparation for the roll-in of the robot was 39.5 min. The median console time was 47.5 min. There were no intraoperative or postoperative complications related to the use of the robot and no in-hospital mortality. In conclusion, HARS seems to be feasible and safe for abdominal manipulation during oesophageal cancer surgery.

Long-term health-related quality of life following robot-assisted radical transmediastinal esophagectomy.

BACKGROUND: The good short-term and oncological outcomes of robot-assisted radical esophagectomy have been demonstrated, although its impact on long-term health-related quality of life (HRQoL) remains to be investigated. This study aimed to assess long-term HRQoL in patients after robot-assisted radical transmediastinal esophagectomy (TME), which is characterized as non-transthoracic esophagectomy comprising a robotic transhiatal approach and a video-assisted cervical approach, and transthoracic esophagectomy (TTE). METHODS: The European Organization for Research and Treatment of Cancer generic and disease-specific modules (QLQ-C30 and QLQ-OES18), nutritional status and body composition data were prospectively collected in patients undergoing TME or TTE before and at 3, 6, 12, 18, and 24 months after surgery. The results of long-term (≥ 2 years) survivors without recurrence were compared between the two groups. RESULTS: A total of 37 patients (TME; n = 18, TTE; n = 19) were included for analysis. Longitudinal survey of function scales revealed scores of physical, role, social, and emotional function to be significantly better in the TME group than in the TTE group at many points postoperatively. Markedly, the symptoms of general pain, esophageal pain, and dry mouth greatly worsened after surgery in the TTE group, but did not deteriorate in the TME group. In contrast, symptoms relating to eating difficulties, body composition data, and nutritional status did not differ between the groups over time. At 24 months after surgery, TME provided significantly higher scores of global QOL (P = 0.01) and emotional function (P = 0.01) and also resulted in significantly fewer problems of fatigue (P = 0.04), general pain (P = 0.04), insomnia (P = 0.02), and dry mouth (P = 0.03), as compared to TTE. CONCLUSION: This study indicates that TME can provide better long-term HRQoL outcomes than TTE.

Long-term outcomes of multimodal therapy combining definitive chemoradiotherapy and salvage surgery for T4 esophageal squamous cell carcinoma.

BACKGROUND: Survival outcomes of patients with cT4 esophageal squamous cell carcinoma (ESCC) remain extremely poor. We aimed to investigate long-term outcomes and identify prognostic factors in patients treated by definitive chemoradiotherapy (dCRT) alone or with dCRT plus salvage surgery (SALV) for cT4 ESCC. PATIENTS AND METHODS: In total, 73 patients completing dCRT were analyzed. Patients achieving clinical complete response (CR) received follow-up evaluations thereafter. For patients diagnosed with clinical partial response (PR), potentially curative SALV was generally performed. Possible prognostic factors included demographic data, tumor staging, blood chemistry profiles, and esophageal stenosis. RESULTS: The 1- and 3-year overall survival (OS) rates of the 73 patients were 67.1% and 40.8%, respectively. Twenty-one patients (29%) achieved clinical CR with dCRT alone. Among 35 patients (48%) with clinical PR, 31 underwent SALV and 4 opted for non-surgical treatments. In the dCRT-alone group (n = 42), patients with clinical CR-PR (n = 25) showed significantly better 3-year OS than those who responded poorly to dCRT (stable or progressive) (n = 17) (67.5% vs. 0%, P < 0.001). In the SALV group (n = 31), curative SALV (n = 22, 73%) provided significantly better 3-year OS than non-curative SALV (58.7% vs. 0%, P < 0.001). Multivariable analysis revealed stenosis before dCRT (P = 0.02) and pretreatment elevated CRP (P = 0.02) to be independently associated with poor outcomes. CONCLUSIONS: The multimodal treatment strategy combining dCRT and SALV is rational for treating cT4 ESCC patients. When curative resection is feasible, SALV can provide good long-term survival outcome for patients who responded to dCRT but did not achieve clinical CR with dCRT alone.

Factors associated with physiological postoperative pyrexia.

AIM: Postoperative pyrexia is generally a physiological response to surgery. It is a common problem and burden for both patients and surgeons. This study aimed to investigate the incidence and duration of physiological postoperative pyrexia and to retrospectively identify the prognostic factors associated with it. METHODS: We reviewed the medical records of 462 patients who underwent surgery for adenomyosis under general anesthesia. Postoperative pyrexia was defined as an axillary temperature of at least 38°C occurring for at least 4 h after the surgery up to the next morning. Long-duration pyrexia was defined as a fever recovery period of >3 days. RESULTS: Of the 367 patients included in this study, 234 (64%) developed postoperative pyrexia and 260 (71%) needed >3 days to recover the normal temperature (<37°C). Multivariate analyses revealed that the administration of an amino acid-enriched solution and non-administration of flurbiprofen were associated with postoperative pyrexia. Scale of surgery (bleeding volume + weight of removed adenomyosis and other tissue), body mass index, and decreased body temperature during surgery were not associated with postoperative pyrexia. Long-duration pyrexia was associated with the scale of surgery but not with the administration of an amino acid-enriched solution and flurbiprofen. CONCLUSION: More than half of the patients developed postoperative pyrexia. Postoperative pyrexia was related to the administration of an amino acid-enriched solution and flurbiprofen. Long-duration pyrexia was associated with the scale of surgery.

Preoperative restrictive pulmonary dysfunction influences the survival after gastrectomy for elderly patients with gastric carcinoma.

PURPOSE: We aimed to evaluate the prognostic impact of pulmonary dysfunctions and their relationships with other possible prognostic factors, especially sarcopenia, in elderly patients with gastric carcinoma (GC). METHODS: In total, 402 elderly GC patients (≥ 75 years) who underwent radical gastrectomy were retrospectively reviewed. Restrictive and obstructive pulmonary dysfunction were defined as %VC < 80% and FEV1.0% < 70%, respectively. RESULTS: Forty-two patients (10.4%) had a low %VC, which was associated with ASA-PS, comorbidity and sarcopenia while correlating with neither the FEV1.0% nor pathological variables. The overall survival in the low %VC group was significantly worse than that in the high %VC group, especially in those with pStage I/II diseases. The survival was not stratified by FEV1.0%. Non-gastric cancer-related deaths were more prevalent in the low %VC group than in the high %VC group. The cancer-specific survival showed no significant differences between the two groups. A multivariate analysis revealed a low %VC to be the most powerful predictor of a poor survival among all independent variables, including sex, age, comorbidity, total gastrectomy, and pStage. Patients with both a low %VC and sarcopenia showed an extremely poor survival. CONCLUSIONS: Preoperative restrictive pulmonary dysfunction was independently associated with poor survival outcomes, especially when present in combination with sarcopenia, due to an increased risk of death from non-cancer-related causes.

Preoperative lymph node status on computed tomography influences the survival of pT1b, T2 and T3 esophageal squamous cell carcinoma.

PURPOSE: The preoperative lymph node status is critical for tailoring optimal treatments for esophageal squamous cell carcinoma (ESCC). This study aimed to evaluate the prognostic impact of a diagnostic criterion based solely on the short-axis diameters of lymph nodes depicted on computed tomography (CT) in ESCC patients undergoing upfront esophagectomy. METHODS: We retrospectively reviewed 246 pT1b-T3 ESCC patients undergoing upfront esophagectomy. Clinically positive lymph node metastasis (cN+) was defined as nodes with a short-axis diameter of at least 8 mm on CT. RESULTS: Ninety-three patients had a cN+ status according to this criterion. The overall and recurrence-free survival rates were significantly lower in the cN+ group than in the cN- group (P < 0.001). The overall survival rate was markedly lower in the "pN2/3 and cN+" group than in the other groups (vs. pN0: P < 0.001, vs. pN1: P = 0.002, vs. "pN2/3 and cN-": P < 0.001). However, the overall survival rate of the "pN2/3 and cN-" group was similar to that of the pN0-1 groups. A multivariate analysis showed that cN+ (P = 0.002), major complications (P = 0.001), and pT3 (P = 0.021) were independently associated with a poor prognosis. CONCLUSION: A diagnostic criterion based solely on the short-axis diameters of lymph nodes depicted on CT was useful for stratifying the survival in ESCC patients.

Quality of life after robot-assisted transmediastinal radical surgery for esophageal cancer.

BACKGROUND: The aim of this retrospective study was to assess postoperative quality of life (QOL) after robot-assisted radical transmediastinal esophagectomy, defined as a nontransthoracic esophagectomy with radical mediastinal lymphadenectomy combining a robotic transhiatal approach and a video-assisted cervical approach. The results were compared to those of transthoracic esophagectomy. METHODS: In this study, all consecutive patients who underwent robot-assisted radical transmediastinal esophagectomy or transthoracic esophagectomy for esophageal cancer at University of Tokyo between January 2010 and December 2014 were included. The European Organization for Research and Treatment of Cancer (EORTC)'s quality of life questionnaires QLQ-C30 and QLQ-OES18 were sent to all patients that were still living, had no recurrence or other malignancy, and had not undergone a reoperation because of complications after esophagectomy. RESULTS: We were able to survey 63 (98.4%) of 64 eligible patients. We assessed and compared the QOL scores of both groups of patients. Compared to transthoracic esophagectomy, transmediastinal esophagectomy was associated with better QOL. Global health status and the physical, role, and cognitive function scale scores were significantly superior in the transmediastinal esophagectomy group (P = 0.004, < 0.0001, 0.007, 0.002, respectively). Fatigue, nausea and vomiting, pain, appetite loss, reflux, and taste scores were significant lower (superior) in the transmediastinal esophagectomy group (P = 0.003, 0.032, 0.025, 0.018, 0.001, 0.041, respectively). CONCLUSIONS: This study indicates that robot-assisted radical transmediastinal esophagectomy is associated with better postoperative QOL compared to transthoracic esophagectomy. A larger study and prospective analyses are needed to confirm the current results.

Pregnancy, delivery, and breastfeeding after total gastrectomy for gastric cancer: a case report.

BACKGROUND: The reports of pregnancy after total gastrectomy for gastric cancer are rare. CASE PRESENTATION: We report a case of a 35-year-old woman, gravida 0, para 0, who became pregnant and delivered a baby 2 years and 6 months after laparoscopic-assisted total gastrectomy for early gastric cancer. Postoperatively, she showed a good progress during the follow-up and was continuously taking oral iron supplement and administered with methylcobalamin intramuscular injection. Two years after gastrectomy, she became pregnant. During the pregnancy, she kept taking iron and vitamin B12 supplementation and had a good course of pregnancy and a normal delivery. However, 2 months after the delivery, liver dysfunction was detected via blood examination. The patient switched from exclusive breastfeeding to combined feeding with formula, and her laboratory results returned to normal. During 10 years of follow-up after the delivery, the patient was in good condition without any recurrence and nutritional deficiencies, and her child had thrived. CONCLUSIONS: Careful monitoring and management of iron and vitamin deficiencies are essential during pregnancy and the lactation periods for patients who previously underwent total gastrectomy. During the lactation period, a combination of formula and breastfeeding provides maternal and fetal nutritional support.

Mediastinoscopic view of the bronchial arteries in a series of surgical cases evaluated with three-dimensional computed tomography.

BACKGROUND: We have routinely performed three-dimensional computed tomography (3-D CT) prior to video-assisted transmediastinal esophagectomy to evaluate the small arteries in the mediastinal operative field. This evaluation would be helpful in performing mediastinoscopic esophagectomy. METHODS: Thirty-one patients who underwent transmediastinal esophagectomy with preoperative evaluations by 3-D CT were the study subject. The bronchial arteries depicted by the 3-D CT were classified by their origin and laterality. In 18 of the 31 cases, the surgical video was available and the identification rate in the video was reviewed for each of the categorized bronchial arteries. RESULTS: The detection rates of each classified artery were as follows (abbreviations, detection rate); the intercostal-bronchial trunk (IBT, 22/31), the direct left bronchial artery (LBA, 17/31), the common trunk of bronchial arteries (CTB, 7/31), the direct right bronchial artery (RBA, 2/31), and the ectopic arteries (16/31). The ectopic arteries arose from the aortic arch (11 cases), the right subclavian artery (6 cases) or the left subclavian artery (1 case). The identification rates of IBT, LBA, CTB, RBA and any of the ectopic arteries in the video review were 12/13, 4/8, 3/4, 1/1 and 2/10, respectively. CONCLUSIONS: Preoperative 3-D CT was a highly sensitive evaluation for the bronchial arteries encountered during transmediastinal esophagectomy. Orthotopic arteries except for LBA were frequently identified at the predicted sites. Although RBA and CTB were present infrequently, they often flowed into regional nodes at the bilateral bronchi or the tracheal bifurcation and, therefore, should be preoperatively evaluated.

[Clinical Practice of Enhanced Recovery after Surgery Program for Esophagectomy].

Enhanced recover after surgery(ERAS) program is multimodal strategies to reduce the incidence of postoperative morbidity and mortality, and encourage early functional recovery from surgical insult. It consists of physical therapy to facilitate postoperative early mobilization, nutritional support, introduction of minimal invasive surgery, restrictive fluid therapy and early resumption of oral intake. Esophagectomy for esophageal cancer is a highly invasive procedure with high incidence of postoperative morbidity and mortality. Although the evidence of ERAS program for esophagectomy has not yet been established, some approaches has been reported with feasible results. This article describes the clinical practices of ERAS program for esophagectomy.

Radical esophagectomy for a 92-year-old woman with granulocyte colony-stimulating factor-producing esophageal squamous cell carcinoma: a case report.

BACKGROUND: Granulocyte colony-stimulating factor (G-CSF)-producing esophageal squamous cell carcinoma (ESCC) has been considered to have a poor prognosis. We successfully treated a case of G-CSF-producing ESCC in a 92-year-old woman. CASE PRESENTATION: A 92-year-old woman was admitted to our hospital with the complaints of choking while swallowing and dysphagia. Esophagogastroduodenoscopy and contrast-enhanced computed tomography revealed a type 2 esophageal cancer located 26-35 cm from the dental arch, with no distant metastasis. The patient was diagnosed with G-CSF-producing ESCC based on remarkable leukocytosis and high G-CSF levels. The patient underwent radical subtotal esophagectomy. Subsequently, the level of neutrophils (from 23,500/µL to 5000/µL) and the level of G-CSF (from 131 to <19.5 pg/mL) decreased significantly. Immunohistochemistry analysis of the resected tissue specimen showed positive staining for G-CSF in the cytoplasm of the tumor cells. Although the patient developed aspiration pneumonitis, after antibiotic treatment, she promptly recovered and was discharged. CONCLUSIONS: Herein, we describe a case of successfully treated G-CSF-producing ESCC in a 92-year-old woman. Precise detection and safely performed immediate radical operation are considered essential to achieve a good clinical course.

Difference in reproductive performance between two subtypes of bicornuate uterus.

PURPOSE: We compared reproductive outcome in patients with two subtypes of bicornuate uterus who underwent a Strassmann metroplasty procedure. METHODS: Eleven patients diagnosed using the R-AFS definition were divided into partial and complete type, then reproductive outcome following a Strassmann metroplasty was evaluated. RESULTS: All four patients with the partial type anomaly conceived and achieved a live birth, while none of the seven with the complete type anomaly were able to conceive. CONCLUSION: Patients with the partial type of bicornuate uterus showed a favorable prognosis after a Strassmann metroplasty. Conversely, those with the complete type should be treated as uterus didelphis, and not undergo a metroplasty.

Association of uterine wall thickness with pregnancy outcome following uterine-sparing surgery for diffuse uterine adenomyosis.

BACKGROUND: The risk of uterine rupture is a major concern for women who become pregnant after undergoing an adenomyomectomy. AIMS: The aim of this study was to investigate the association of uterine wall thickness with pregnancy outcome. MATERIALS AND METHODS: Uterine wall thickness was measured using sonography and/or magnetic resonance imaging in 23 pregnant women who underwent uterine-sparing surgery for diffuse uterine adenomyosis prior to conception. RESULTS: Of the 23 women, 10 (43.5%) had an early miscarriage and 13 (56.5%) proceeded to delivery. Of the ten early miscarriage cases, two had a uterine rupture caused by excision of the uterine wall to within 7 mm. CONCLUSIONS: Wall thickness of the excised uterus was highly associated with uterine rupture. We concluded that optimum wall thickness for conception and preventing uterine rupture during pregnancy may range from 9 to 15 mm.

Palliative distal gastrectomy offers no survival benefit over gastrojejunostomy for gastric cancer with outlet obstruction: retrospective analysis of an 11-year experience.

BACKGROUND: Either palliative distal gastrectomy or gastrojejunostomy are the initial treatment options for locally advanced gastric cancer with outlet obstruction when curative-intent resection is not feasible. Since chemotherapy is the mainstay for unresectable gastric cancer, the clinical value of palliative distal gastrectomy is controversial. METHODS: We retrospectively reviewed the clinical data of patients with gastric cancer with outlet obstruction treated at our institution between January 2002 and December 2012. We compared the clinical outcomes of palliative distal gastrectomy with those of gastrojejunostomy patients and the factors affecting overall survival were evaluated. RESULTS: Elective palliative distal gastrectomy and gastrojejunostomy were performed in 18 and 25 patients, respectively. The median overall survival times in the gastrojejunostomy and palliative distal gastrectomy groups were statistically equivalent at 8.8 and 8.3 months, respectively (P = 0.73), despite the more locally advanced tumors in the gastrojejunostomy as compared with the palliative distal gastrectomy group. A multivariate Cox regression analysis showed absence of postoperative chemotherapy and higher postoperative complication grade to be associated with worse clinical outcomes. CONCLUSIONS: Palliative distal gastrectomy offers neither survival nor palliative benefit as compared to gastrojejunostomy. Minimizing the morbidity of intervention for outlet obstruction, followed by chemotherapy, appears to be the optimal initial strategy for incurable gastric cancer with outlet obstruction.
