Laparoscopic ventral rectopexy using the transanal vacuum test for complete rectal prolapse.

Laparoscopic ventral rectopexy was performed in 84 patients with complete rectal prolapse from January 2016 to December 2019. In the initial 27 cases, three cases had recurrence, especially in cases of a long rectal prolapse measuring over 10 cm. In order to avoid recurrence, the transanal vacuum test was performed following the dissection of the rectovaginal septum towards the pelvic floor. The disappearance of rectal prolapse is confirmed by the intraoperative transanal vacuum test. When the posterior wall of the rectum showed the presence of prolapse according to the transanal vacuum test, then laparoscopic ventral rectopexy was converted to laparoscopic posterior rectopexy. In 94 cases in which laparoscopic ventral rectopexy was attempted, laparoscopic ventral rectopexy was completed in 57 cases, while the procedure was converted to laparoscopic posterior rectopexy in 37 cases. The recurrence rate following laparoscopic ventral rectopexy decreased from 11.1% (3/27) to 1.7% (1/57) after beginning to use the transanal vacuum test. Laparoscopic ventral rectopexy using the transanal vacuum test is therefore considered to be a useful technique to reduce postoperative recurrence.

Mucosal perforation during laparoscopic surgery for achalasia: impact of preoperative pneumatic balloon dilation.

BACKGROUND: Controversy remains whether preoperative pneumatic balloon dilation (PBD) influences the surgical outcome of laparoscopic esophagocardiomyotomy in patients with esophageal achalasia. The aim of this study was to evaluate whether preoperative PBD represents a risk factor for surgical complications and affects the symptomatic and/or functional outcomes of laparoscopic Heller myotomy with Dor fundoplication (LHD). METHODS: A retrospective chart review was conducted on a prospectively compiled surgical database of 103 consecutive patients with esophageal achalasia who underwent LHD from November 1994 to September 2014. The following data were compared between the patients with preoperative PBD (PBD group; n = 26) and without PBD (non-PBD group; n = 77): (1) patients' demographics: age, gender, body mass index, duration of symptoms, maximum transverse diameter of esophagus; (2) operative findings: operating time, blood loss, intraoperative complications; (3) postoperative course: complications, clinical symptoms, postoperative treatment; and (4) esophageal functional tests: preoperative and postoperative manometric data and postoperative profile of 24-h esophageal pH monitoring. RESULTS: (1) No significant differences were observed in the patients' demographics. (2) Operative findings were similar between the two groups; however, the incidence of mucosal perforation was significantly higher in the PBD group (n = 8; 30.7 %) compared to the non-PBD group (n = 6; 7.7 %) (p = 0.005). (3) Postoperative complications were not encountered in either group. The differences were not significant for postoperative clinical symptoms, the incidence of gastroesophageal reflux disease, or necessity of postoperative treatments. (4) Lower esophageal sphincter pressure was effectively reduced in both groups, and no differences were observed in manometric data or 24-h pH monitoring profiles between the two groups. Multivariate logistic regression analysis showed that preoperative PBD and the maximum transverse diameter of esophagus were significantly associated with intraoperative mucosal perforation. CONCLUSIONS: Although postoperative outcomes were not affected, additional caution is recommended in identifying intraoperative mucosal perforation in patients with preoperative PBD when performing LHD.

Assessment of postoperative quality of life following pylorus-preserving gastrectomy and Billroth-I distal gastrectomy in gastric cancer patients: results of the nationwide postgastrectomy syndrome assessment study.

BACKGROUND: Pylorus-preserving gastrectomy (PPG) is increasingly being used to treat early gastric cancer in the middle third of the stomach, with the hope of ameliorating postoperative dysfunction and improving quality of life (QOL). We evaluated symptoms of postgastrectomy syndrome (PGS) and QOL by means of a newly developed integrated questionnaire, the Postgastrectomy Syndrome Assessment Scale-45 (PGSAS-45), and compared PPG with Billroth-I distal gastrectomy (DGBI). METHODS: The PGSAS-45 consists of 45 items, including items from the SF-8 and GSRS instruments, as well as 22 newly selected items. It was designed to assess the severity of PGS and the living status and QOL of gastrectomized patients. The nationwide PGSAS surveillance study enrolled 2,368 gastric cancer patients who underwent various types of gastrectomy. In this study we analyzed 313 PPG patients and 909 DGBI patients. RESULTS: Body weight loss was -6.9% in the PPG group and -7.9% in the DGBI group (P = 0.052). The PPG group scored better on the diarrhea subscale (PPG; 1.8 vs. DGBI; 2.1, P < 0.0001), dumping subscale (1.8 vs. 2.0, P = 0.003), and frequency of additional meals (1.8 vs. 1.9, P = 0.034). Multiple regression analysis revealed that age and the preservation of the celiac branch of the vagus nerve were independent factors predicting diarrhea and dumping. CONCLUSIONS: It has been suggested that PPG is superior to DGBI for ameliorating PGS. Preservation of the celiac branch of the vagus nerve is recommended to reduce postoperative disorders regardless of the reconstruction method used.

Factors that minimize postgastrectomy symptoms following pylorus-preserving gastrectomy: assessment using a newly developed scale (PGSAS-45).

BACKGROUND: Pylorus-preserving gastrectomy (PPG) is sometimes performed as a function-preserving surgery for the treatment of early gastric cancer. The aim of this study was to use an integrated assessment scale for postgastrectomy syndrome to determine the appropriate indicators and optimal methods for PPG. METHODS: The Postgastrectomy Syndrome Assessment Study (PGSAS) is a multicenter survey based on an integrated questionnaire (PGSAS-45) consisting of 45 items. Questionnaire responses were retrieved from a total of 2,520 patients, each of whom had undergone one of six different types of gastrectomy procedures; 313 responses from patients who had received PPG were analyzed here. RESULTS: The size of the proximal gastric remnant (less than one-quarter, about one-third, or more than one-half of the original size) significantly influenced the change in body weight, the scores for dissatisfaction at the meal, and dissatisfaction for daily life subscale (P = 0.030, P = 0.005, P = 0.034, respectively). The nausea score in patients who underwent hand-sewn anastomosis was significantly lower than in those who underwent anastomosis with a linear stapler (P = 0.006). The scores for diarrhea subscale, increased passage of stools, and sense of foods sticking differed significantly depending on the length of the preserved pyloric cuff (P = 0.047, P = 0.021, P = 0.046, respectively). CONCLUSIONS: The results suggest that preservation of a sufficient proximal gastric remnant is recommended when utilizing PPG as function-preserving surgery.

Evaluation of QOL after proximal gastrectomy using a newly developed assessment scale (PGSAS-45).

BACKGROUND: Proximal gastrectomy with esophagogastrostomy (PGEG) has been widely applied as a comparatively simple method. In this study, we used a questionnaire survey to evaluate the influence of various surgical factors on post-operative quality of life (QOL) after PGEG. METHODS: In this post-gastrectomy syndrome assessment study, we analyzed QOL in 2,368 cases. Among these, 193 had undergone proximal gastrectomy and 115 had undergone PGEG. The Post-Gastrectomy Syndrome Assessment Scale (PGSAS)-45 is a questionnaire consisting of 45 items, including the SF-8, the Gastrointestinal Symptom Rating Scale (GSRS), and other symptom items seemed to be specific to post-gastrectomy. The 23 symptom items were composed of seven symptom subscales (SS), including esophageal reflux, abdominal pain, and meal-related distress. These seven SS, total symptom score, ingested amount of food per meal, necessity for additional meals, quality of ingestion SS, ability to work, dissatisfaction with symptoms, dissatisfaction with the meal, dissatisfaction with working, dissatisfaction with daily life SS and change in body weight were evaluated as main outcome measures. In PGEG cases, we evaluated the influence on QOL of various surgical factors, such as procedures to prevent gastroesophageal regurgitation and size of the remnant stomach. RESULTS: The scores for esophageal reflux and dissatisfaction with the meal were higher in patients who had not undergone an anti-reflux procedure. In most cases, the preserved remnant stomach was more than two-thirds the size of the pre-operative stomach. When comparing patients with a remnant stomach two-thirds the pre-operative size and those with more than three-quarters, the diarrhea SS and necessity for additional meals scores were lower in the group with more than three-quarters. The indigestion, constipation, and abdominal pain subscales, and the total symptom score, were higher in patients who had not undergone pyloric bougie than in those who had. CONCLUSION: These results indicated that QOL was better in patients with a large remnant stomach. Procedures to prevent gastroesophageal reflux, and the use of pyloric bougie as a complementary drainage procedure, were considered effective ways to reduce the deterioration of QOL.

Assessing clinical benefit response in the treatment of gastric malignant ascites with non-measurable lesions: a multicenter phase II trial of paclitaxel for malignant ascites secondary to advanced/recurrent gastric cancer.

BACKGROUND: Paclitaxel has shown promise against advanced gastric cancer and associated malignant ascites with non-measurable lesions. In order to evaluate the therapeutic effect of paclitaxel against malignant gastric ascites, a prospective phase II clinical trial was designed according to our previously proposed criteria represented by the clinical benefit response in gastric cancer (CBR-GC) criteria and the five-point method (5PM). METHODS: Patients with advanced gastric cancer with malignant ascites were treated with 1-h intravenous (i.v.) infusions of 80 mg/m² of paclitaxel weekly over a 3-week cycle on days 1, 8, and 15, followed by 1 week of rest. Therapeutic responses were measured according to the CBR-GC criteria and the 5PM. RESULTS: The CBR-GC criteria showed improved ascites volume and functional status in 39.1% of patients. A positive CBR-GC response in abdominal girth was seen in 31.3% of patients, and this was significantly correlated with the 5PM-estimated change in ascites volume (p < 0.001). The median number of treatment cycles was 3 (range 1-12). The most common non-hematological toxicity was anorexia, in 22.2% of patients. CONCLUSION: Weekly i.v. paclitaxel is a safe and effective chemotherapeutic regimen based on validated CBR-CG criteria.

Dedifferentiated liposarcoma in the retroperitoneum in an atomic bomb survivor: report of a case.

A 76-year-old Japanese man was admitted to Kosei-Nenkin Hospital (Osaka, Japan) in November 2006; his chief complaint was a 10-kg loss in body weight over 3 months prior to admission. Abdominal computed tomography (CT) and dynamic magnetic resonance imaging (MRI) showed three masses in the retroperitoneum. The patient subsequently underwent surgery. The final histopathological diagnosis of tumors 1 and 2 was malignant fibrous histiocytoma of the retroperitoneum, and tumor 3 was a well-differentiated liposarcoma. By the presence of the liposarcoma, tumor 1 and 2 were thought to be the dedifferentiated areas of liposarcomas. At the age of 16, the patient had been exposed to radiation from the atomic bomb at Hiroshima towards the end of the Second World War. We postulate that in this case, radiation from the atomic bomb may have played an important role in the development of the sarcomas.

[Two cases of stage IV gastric cancer responding to chemotherapy with S-1 or UFT].

We report patients with advanced Stage IV gastric cancer responding to chemotherapy with S-1 or UFT. Case 1: The patient was a 59-year-old man with Stage IV gastric cancer because of CY 1. After surgery, chemotherapy with S-1 (100 mg/body/day) was performed for one year and 11 months. At present, 5 years and 5 months after surgery, this patient shows no signs of tumor recurrence. Case 2: The patient was a 68-year-old woman with Stage IV gastric cancer because of P 1. She was treated with 200 mg/day of UFT for one year and 9 months. At present, 5 years after surgery, she shows no signs of tumor recurrence. We considered that the longterm survival of such patients is attributable to chemotherapy with S-1 or UFT. The OPRT activity of the two cases was high, so chemotherapy with S-1 or UFT was thought to be effective for them.

[A case of stage IV gastric cancer treated sequentially for over two years by TS-1, paclitaxel, and CPT-11].

We report a patient with advanced stage IV gastric cancer treated by chemotherapy for over two years. The patient was a 69-year-old man with paraaortic lymph node metastasis of gastric cancer. He underwent a distal gastrectomy in non-curative resection. After surgery, chemotherapy with TS-1 (100 mg/body/day) was performed. At 7 months after surgery, progression of lymph node metastasis in porta hepatis was recognized, and paclitaxel was administered at a weekly dose of 80 mg/m(2) for 3 weeks followed by one week rest. He remained stable for 12 months under paclitaxel treatment. At 26 months after surgery, progression of lymph node metastasis in porta hepatis was recognized again, and CPT-11 was administered at a bi-weekly dose of 80 mg/m(2). Although the patient died two years seven months after surgery, the chemotherapy with sequential administration of TS-1, paclitaxel and CPT-11 was thought to be effective for advanced gastric cancer.

Motility of the pouch correlates with quality of life after total gastrectomy.

BACKGROUND: Jejunal pouch reconstruction is used to provide reservoir function after total gastrectomy, but controversy remains regarding pouch functions and quality of life (QOL). In this study, pouch motility was studied in conjunction with postoperative QOL. METHODS: Pouch motility of 23 patients with jejunal pouch interposition after total gastrectomy was examined by manometry under fasting conditions and by an emptying test using dual-scintigraphy under postprandial conditions. Residual food was graded by endoscopic examinations. QOL was evaluated using the Gastrointestinal Quality of Life Index, and a stasis- or dumping-related symptom score. RESULTS: The pouch showed interdigestive contractile activity. Bursts of contractile activity occurred frequently and were long-lasting compared with the migrating motor complex phase III of the control jejunum. The percentage of time of contractile bursts correlated with postprandial pouch emptying (liquid: R(2) = 0.229, P < .03; solid: R(2) = 0.243, P < .02). Patients with little or no residual food had more percentage of time of contractile bursts than those with moderate residual food (P < .01). The percentage of time of contractile bursts was correlated with the Gastrointestinal Quality of Life Index score (R(2) = 0.262, P < .02), stasis-related symptoms (R(2) = 0.279, P < .01), and dumping-related symptoms (R(2) = 0.218, P < .03). CONCLUSIONS: An interposed jejunum pouch showed bursts of contractile activity that affected postoperative gastrointestinal function and patient QOL.

Jejunal pouch interposition with fundic-like plication after total gastrectomy.

PURPOSE: We developed a technique of jejunal pouch interposition with a fundic-like jejunal plication (JPI-FP) for reconstruction after total gastrectomy (TG) for gastric cancer. The aim of this study was to investigate the advantages of JPI-FP over Roux-en-Y reconstruction (R-Y). METHODS: Twenty-two patients who had undergone TG more than 1 year earlier were classified into two groups according to the method of reconstruction used: Group A (n = 7) underwent R-Y, and group B (n = 15) underwent JPI-FP. Group B was subdivided into two groups to examine the usefulness of additional pylorus preservation: group B1 (n = 8), pylorus (-) and group B2 (n = 7), pylorus (+). RESULTS: Food intake and body weight were significantly higher in group B than in group A (P < 0.05). Reflux esophagitis was diagnosed in two of the group A patients, but in none of the group B patients. Excessive esophageal bile exposure, determined as the fraction time of esophageal bilirubin absorbance over 0.14 > 50%, was significantly higher in group A than in group B (P < 0.05). There was no significant difference in bile exposure in the jejunal pouch between groups B1 and B2. CONCLUSIONS: JPI-FP is a superior method of reconstruction after TG to prevent excessive esophageal bile reflux and from a nutritional aspect. The advantage of pylorus preservation remains unconfirmed.

Gastropleural fistula due to gastric perforation after lobectomy for lung cancer.

We report a case of acute gastropleural fistula due to gastric perforation after a left lower lobectomy for lung cancer. A 76-year-old male, who received a left hemicolectomy 20 years previously, came to our hospital for surgical treatment of lung cancer, which was performed uneventfully as a left lower lobectomy with combined resection of the diaphragm. On the postoperative day 2, acute dilatation of the stomach followed by gradual cardiopulmonary collapse, and then gastric perforation into the thorax occurred. The perforated stomach wall and diaphragm became paper-thin and necrotic, though the abdominal cavity was free of contamination. This life-threatening condition was treated by an emergency thoracotomy and partial gastrectomy through the thorax, as the left hemidiaphragm was remarkably elevated. An oeganoaxial torsion gastric volvulus caused by anatomic rotation following the lobectomy was speculated as the disease process, with loss of suspended tissue of the gastro-colic ligament from the left hemicolectomy being a possible predisposing factor. Such an episode is rare, however, it should be looked for during perioperative care following a lobectomy.

A new parameter for assessing postoperative recovery of physical activity using an accelerometer.

PURPOSE: While many retrospective and prospective observational studies have shown laparoscopic surgery to be less invasive than conventional open surgery, this issue has not been evaluated by objective parameters. Currently available clinical parameters, such as the day of first ambulation, the day food intake is commenced, and the length of postoperative hospital stay, are subjective. The purpose of this study was to investigate whether measuring postoperative physical activity with an accelerometer is a useful parameter for evaluating postoperative recovery after surgical stress. METHODS: The subjects included 20 patients who underwent laparoscopic partial gastrectomy (LPG group), 35 patients who underwent open distal gastrectomy (ODG group), and 20 patients who underwent open total gastrectomy (OTG group). The cumulative acceleration of voluntary movement, measured by an Active tracer AC-301 (ACT) accelerometer for 7 days postoperatively, was compared among these three groups. RESULTS: The cumulative acceleration of physical activity for 24 h was significantly better in the LPG group than in the ODG and OTG groups on each postoperative day. The recovery time, defined as the day that cumulative acceleration had recovered to more than 90% of the preoperative level, was significantly shorter in the LPG group (2.8 +/- 0.9 days) than in the ODG (6.6 +/- 2.1 days) and OTG (7.8 +/- 1.2 days) groups. CONCLUSION: These results showed that convalescence differed with the degree of surgical stress, and that measurement of the cumulative acceleration of voluntary movement by using an accelerometer could be a useful objective and quantitative parameter for evaluating postoperative recovery.

A phase II clinical trial to evaluate the effect of paclitaxel in patients with ascites caused by advanced or recurrent gastric carcinoma: a new concept of clinical benefit response for non-measurable type of gastric cancer.

A phase II clinical trial has started in the South West region of Japan to investigate the efficacy and safety of weekly paclitaxel chemotherapy for the treatment of patients with ascites-forming advanced gastric cancer. A novel trial design was created to assess more effectively prospective changes in symptomatology. The study design focuses on the typical features seen in patients with ascites-forming advanced gastric cancer, including girth of the abdomen and impaired performance status, which is evaluated in the endpoint of 'Clinical Benefit Response - Gastric Cancer'. The more traditional endpoints, objective tumor response and survival, are also included. As nearly 40% of patients with this disease are excluded from traditional phase II trials owing to the absence of 'measurable' disease, this study should more precisely illustrate the disease entity affecting patients with advanced gastric cancer.

Effect of mucosal suture on the healing of mucosal defect in laparoscopic intragastric surgery.

BACKGROUND: The efficacy of mucosal suturing for the healing of a mucosal defect in laparoscopic intragastric surgery (LIGS) for gastric lesions is not yet known. METHODS: We prospectively studied ten patients who underwent mucosal resection by LIGS for gastric tumors: four patients with early gastric cancer and six with gastric adenoma. Patients were randomly divided into two groups: group I (n = 5); patients who underwent mucosal resection by LIGS with mucosal defect suturing and group II (n = 5); patients who underwent mucosal resection by LIGS without mucosal defect suturing. We performed endoscopy on day 10, and 1 month, 2 months, and 3 months after the operation to observe the healing process of the mucosal defect. The ulcer stage by endoscopy was classified as active, healing, or scarring according to the classification of Sakita and colleagues. Patients were given an H(2)-blocker daily until the mucosal defect improved to the scarring stage. RESULTS: There were no significant differences in sex, age, tumor location, size of mucosal resection, or the incidence of Helicobacter pylori infection between groups I and II. The ulcer stages in group I were significantly lower than those in group II on day 10, and 1 month, 2 months, and 3 months postoperation. The medication cost (H2-blocker) in group I was significantly lower than that in group II. CONCLUSION: Mucosal defect suturing after mucosal resection by LIGS promotes more rapid healing of mucosal defects and reduces drug costs for patients.
