[Double-tract reconstruction after gastrectomy for gastric cancer in patients with concomitant cardiovascular diseases]. / Rekonstruktsiya double-tract posle gastrektomii po povodu raka zheludka u patsientov s konkuriruyushchimi serdechno-sosudistymi zabolevaniyami.

OBJECTIVE: To demonstrate the capabilities and advantages of double-tract reconstruction after gastrectomy for gastric cancer and simultaneous approach in surgical treatment of patients with cardiovascular diseases and gastric cancer. MATERIAL AND METHODS: We present two cases of double-tract reconstruction after gastrectomy and the gastric stump extirpation as a part of simultaneous surgical approach to patients with gastric cancer and cardiovascular diseases. A 62-year-old patient underwent simultaneous gastrectomy with double-tract reconstruction (for the first time In Russia) and aortofemoral replacement. A 61-year-old patient underwent simultaneous coronary artery bypass surgery, gastric stump extirpation with esophagogastrostomy and double-tract reconstruction. RESULTS: In 1 case, postoperative period was complicated by subcompensated stenosis of the right ureter due to hematoma near the right common iliac artery. This event required endoscopic stenting of the right ureter with positive effect. Both patients were discharged in 16 and 23 days after surgery. CONCLUSION: This method may be alternative to modern reconstructions. Currently, digestive tract reconstruction after gastrectomy is still important and requires further study. Simultaneous procedures in patients with cancer and cardiovascular disease became more widespread. To objectify our statements, further research is needed.

The safety, feasibility, and oncological outcomes of laparoscopic completion total gastrectomy for remnant gastric cancer: a prospective study with 3-year follow-up (FUGES-004 study).

BACKGROUND: The efficacy of laparoscopic completion total gastrectomy (LCTG) for remnant gastric cancer (RGC) remains controversial. METHODS: The primary outcome was postoperative morbidity within 30 days after surgery. Secondary outcomes included 3-year disease-free survival (DFS), 3-year overall survival (OS), and recurrence. Inverse probability treatment weighted (IPTW) was used to balance the baseline between LCTG and OCTG. RESULTS: Final analysis included 46 patients with RGC who underwent LCTG at the FJMUUH between June 2016 and June 2020. The historical control group comprised of 160 patients who underwent open completion total gastrectomy (OCTG) in the six tertiary teaching hospitals from CRGC-01 study. After IPTW, no significant difference was observed between the LCTG and OCTG groups in terms of incidence (LCTG vs. OCTG: 28.0 vs. 35.0%, P =0.379) or severity of complications within 30 days after surgery. Compared with OCTG, LCTG resulted in better short-term outcomes and faster postoperative recovery. However, the textbook outcome rate was comparable between the two groups (45.9 vs. 32.8%, P =0.107). Additionally, the 3-year DFS and 3-year OS of LCTG were comparable to those of OCTG (DFS: log-rank P =0.173; OS: log-rank P =0.319). No significant differences in recurrence type, mean recurrence time, or 3-year cumulative hazard of recurrence were observed between the two groups (all P >0.05). Subgroup analyses and concurrent comparisons demonstrated similar trends. CONCLUSIONS: This prospective study suggested that LCTG was noninferior to OCTG in both short-term and long-term outcomes. In experienced centers, LCTG may be considered as a viable treatment option for RGC.

Safe and Accurate Laparoscopic Total Gastrectomy for Remnant Gastric Cancer With Severe Adhesions Using Indocyanine Green Fluorescence Imaging: Guidance in Detection of the Accurate Dissection Layer to Avoid Organ Injury.

Laparoscopic total gastrectomy (LTG) for remnant gastric cancer (RGC) requires advanced techniques due to severe postoperative adhesions and anatomic changes. We performed LTG in 2 patients with RGC using intraoperative indocyanine green (ICG) fluorescence imaging. Both cases previously underwent distal gastrectomy with Billroth-I reconstruction for gastric cancer and were subsequently diagnosed with early-stage gastric cancer of the remnant stomach. Indocyanine green (2.5 mg/body) was administered intravenously during surgery. The liver and common bile duct were clearly visualized during surgery using near-infrared fluorescence laparoscopy, and the adhesions between the hepatobiliary organs and remnant stomach were safely dissected. Laparoscopic total gastrectomy was successfully performed without complications, and the postoperative course was uneventful in both cases. Intraoperative real-time ICG fluorescence imaging allows clear visualization of the liver and common bile duct and can be useful in LTG for RGC with severe adhesions.

[Comparison of quality-of-life after proximal gastrectomy with double tract reconstruction versus gastric tube reconstruction in patients with proximal gastric cancer].

Objective: To compare the surgical safety and postoperative quality of life between proximal gastrectomy with double tract reconstruction (PG-DT) and proximal gastrectomy with gastric tube reconstruction (PG-GT) for proximal gastric cancer. Methods: This was a retrospective cohort study of clinical and follow-up data of 99 patients with proximal gastric cancer who had undergone double tract or gastric tube surgery in Nanjing Drum Tower Hospital from January 2016 to September 2021. We allocated them to two groups according to surgical procedure, namely a double tract group (PG-DT, 50 patients) and gastric tube group (PG-GT, 49 patients). Proximal gastrectomy with double tract reconstruction entails constructing a Roux-en-Y esophagojejunostomy after severing the proximal stomach, and then constructing a side-to-side anastomosis between the residual stomach and the jejunum to establish an anti-reflux barrier and thus minimize postoperative gastroesophageal reflux. Proximal gastrectomy with gastric tube reconstruction entails severing the proximal gastric stomach, constructing a tubular shaped gastric remnant, and then using a linear stapler to directly anastomose the posterior wall of the esophagus to the anterior wall of the resultant gastric tube. The primary end point was the quality of life of the two groups 1 year postoperatively (post-gastrectomy syndrome assessment scale: the higher the scores for change in body mass, food intake per meal, meal quality subscale, total physical health measurement, and total mental health measurement, the better the quality-of-life, and the higher the scores for other indicators, the worse the quality-of-life). The secondary end points were intraoperative and postoperative status, changes in nutritional status 1, 3, 6, and 12 months postoperatively, and long-term postoperative complications (gastroesophageal reflux, anastomotic stenosis, intestinal obstruction, and gastric emptying disorder 1 year postoperatively). Results: In the PG-DT group, there were 35 (70%) men and 15 (30%) women, 33 (66.0%) patients were aged <65 years, and 37 (74.0%) of them had a body mass index of 18-25 kg/m2; whereas in the PG-GT group, there were 41 (83.7%) men and eight (16.3%) women, 21 (42.9%) patients aged <65 years, and 34 (69.4%) patients with a body mass index of 18-25 kg/m2. There were no significant differences in baseline data between the two groups except for age (P=0.021). There were no significant differences in intraoperative blood loss, number of lymph node dissected, length of hospital stay, and incidence of perioperative complications between the two groups (all P>0.05). Compared with the PG-GT group, the incidence and severity of postoperative reflux esophagitis were significantly lower in the PG-DT group (4.0% [2/50] vs. 26.5% [13/49], χ2=13.507, P=0.009). The incidences of postoperative anastomotic stenosis, intestinal obstruction, and gastric retention did not differ significantly between the two groups (all P>0.05). Patients in the PG-DT group had better quality-of-life scores for esophageal reflux (2.8 [2.3,4.0] vs. 4.8 [3.8,5.0], Z=3.489, P<0.001), eating discomfort (2.7 [1.7,3.0] vs. 3.3 [2.7,4.0 ], Z=3.393, P=0.001), and total symptoms (2.3 [1.7,2.7] vs. 2.5 [2.2,2.9], Z=2.243, P=0.025) than those in the gastric tube group; The scores for postoperative symptoms (2.0 [1.0,3.0] vs. 2.0 [2.0, 3.0], Z=2.127, P=0.033), meals consumed (2.0 [1.0, 2.0] vs. 2.0 [2.0, 3.0], Z=3.976, P<0.001), work (1.0 [1.0, 2.0] vs. 2.0 [1.0, 2.0], Z=2.279, P=0.023] and daily life (1.7 [1.3, 2.0] vs. 2.0 [2.0, 2.3], Z=3.950, P<0.001) were better in the PG-DT than the PG-GT group. Patients in the PG-GT group scored better than those in the PG-DT group for somatic symptoms, such as anal evacuation (3.0 [2.0, 4.0] vs. 3.5 [2.0, 5.0], Z=2.345, P=0.019). There were no significant differences in hemoglobin, serum albumin, serum total protein, or weight loss 1 year postoperatively between the two groups (all P>0.05). Conclusions: The safety of double tract anastomosis for proximal gastric cancer is comparable to that of gastric tube surgery. Compared with gastric tube surgery, double tract anastomosis achieves less esophageal reflux and better quality of life, making it a preferable surgical procedure for proximal gastric cancer.

Choice of digestive tract reconstruction in upper gastric cancer / 中华胃肠外科杂志

With the increasing incidence of upper gastric cancer and early gastric cancer, surgeons have gradually paid attention to the selection of appropriate digestive tract reconstruction methods. At present, the safety of surgery is no longer the main aim pursued by surgeons, and the focus of surgery has gradually changed to postoperative quality of life. Surgical procedures for upper gastric cancer include total gastrectomy (TG) and proximal gastrectomy (PG). Roux-en-Y anastomosis is recommended for digestive tract reconstruction after TG. The classic method of digestive tract reconstruction after PG is distal residual stomach and esophageal anastomosis. However, to prevent esophageal reflux caused by PG, a lot of explorations have been carried out over the years, including tubular gastroesophageal anastomosis, double-flap technique (Kamikawa anastomosis), interposition jejunum, double-tract reconstruction and so on. But the appropriate method of digestive tract reconstruction for upper gastric cancer is still controversial. In this paper, based on literatures and our clinical experience, the selection, surgical difficulties and techniques of digestive tract reconstruction after PG are discussed.

Surgical results of remnant gastric cancer treatment / Resultados cirúrgicos do tratamento dos tumores do coto gástrico

ABSTRACT Background: remnant gastric cancer (RGC) develops five years or later after previous resection for benign or malignant lesion. The treatment is performed through completion total gastrectomy (CTG) with radical lymphadenectomy. Some reports consider this procedure may be associated with higher rates of morbidity and mortality. Objective: to evaluate surgical results and survival after CTG in patients with RGC. Methods: 54 patients who underwent CTG between 2009 and 2019 were included in the study. As a comparison group 215 patients with primary gastric cancer (PGC) who underwent total gastrectomy (TG) in the same period were selected. Results: among the initial characteristics, age (68.0 vs. 60.5; p<0.001), hemoglobin values (10.9 vs. 12.3; p<0.001) and body mass index (22.5 vs. 24.6; p=0.005) were different between the RGC and PGC groups, respectively. The most frequent postoperative complications were related to pulmonary complications, infection and fistula in both groups. There was a higher incidence of esophagojejunal fistula in the CTG group (14.8% vs 6.5%, p=0.055). Perioperative mortality was higher in RGC patients (9.3% vs. 5.1%), but without significance (p=0.329). Hospital length of stay, postoperative complications graded by the Clavien-Dindo classification, mortality at 30 and 90 days were not different between groups. There was no significant difference in disease-free and overall survival between RGC and PGC groups. Conclusion: despite previous reports, surgical results and survival were similar between groups. Higher risk of esophagojejunal fistula must be considered.

RESUMO Antecedentes: o câncer do coto ou remanescente gástrico (CRG) se desenvolve cinco anos ou mais após a ressecção gástrica por lesão benigna ou maligna. O tratamento é realizado através da gastrectomia total complementar (GTC) com linfadenectomia. Alguns relatos consideram que esse procedimento pode estar associado a maiores taxas de morbimortalidade. Objetivo: avaliar os resultados cirúrgicos e a sobrevida após GTC em pacientes com CRG. Métodos: 54 pacientes submetidos a GTC entre 2009 e 2019 foram incluídos no estudo. Como grupo de comparação, foram selecionados 215 pacientes com câncer gástrico primário (CGP) submetidos à gastrectomia total (GT) no mesmo período. Resultados: dentre as características iniciais, a idade média (68,0 vs. 60,5; p <0,001), os valores de hemoglobina (10,9 vs. 12,3; p <0,001) e o índice de massa corporal (22,5 vs. 24,6; p = 0,005) diferiram entre os grupos CRG e CGP, respectivamente. As complicações pós-operatórias mais frequentes foram pulmonares, infecciosas e fístulas nos dois grupos. Houve maior incidência de fístula esofagojejunal no grupo GTC (14,8% vs 6,5%, p = 0,055). A mortalidade perioperatória foi maior nos pacientes com CRG (9,3% vs. 5,1%), mas sem significância (p = 0,329). O tempo de internação hospitalar, complicações pós-operatórias (Clavien-Dindo), mortalidade aos 30 e 90 dias não foram diferentes entre os grupos. Não houve diferença significativa na sobrevida livre de doença e global entre os grupos CRG e CGP. Conclusão: apesar dos relatos anteriores, os resultados cirúrgicos e a sobrevida foram semelhantes entre os grupos. Maior risco de fístula esofagojejunal dever ser considerado.

Mixed adenoneuroendocrine carcinoma (MANEC) of the gastroesophageal junction: a case report and review of the literature

Esophageal cancer is the fourth most common neoplasm of the gastrointestinal tract. It is responsible for 1.7% of all deaths related with cancer. The two main types of esophageal cancer are squamous cell carcinoma and adenocarcinoma. Other types of esophageal cancer are uncommon. We present a 57-year-old man admitted to the hospital with nausea and vomiting due to a high-grade malignant mixed adenoneuroendocrine carcinoma of the gastroesophageal junction. The patient underwent Ivor-Lewis esophagectomy and adyuvant chemoradiotherapy. At 8-month follow-up he was alive without evidence of recurrence (AU)

Mixed adenoneuroendocrine carcinoma of the gastric stump following Billroth II gastrectomy: case report and review of the literature / Adenocarcinoma neuroendócrino misto do coto gástrico após gastrectomia à Billroth II: relato de caso e revisão de literatura

CONTEXT: Gastric stump cancer after gastric resection is a well-known disease. It may be a newly developed cancer after resection due to benign disease, or recurrent or residual disease after oncological surgery. The predominant histological type is usually adenocarcinoma. This study aimed to report on a rare occurrence of a mixed adenoneuroendocrine carcinoma (MANEC) on the gastric stump. CASE REPORT: The case of an 83-year-old female who presented a locally aggressive gastric stump MANEC, 35 years after Billroth II gastrectomy to treat a peptic ulcer, is reported. The patient underwent resection and adjuvant therapy. She has been followed up for one year without signs of recurrence. CONCLUSION: MANEC is a rare type of gastrointestinal neoplasm. The classification, histopathology, clinical features, treatment issues and prognosis are discussed along with a brief review of the literature.

CONTEXTO: O câncer de coto gástrico após gastrectomia é uma condição extensamente documentada. Pode se tratar de doença desenvolvida após a ressecção por doença benigna, ou ainda doença recorrente ou residual após cirurgia oncológica. Geralmente, o tipo histológico predominante é o adenocarcinoma. Este estudo tem como propósito relatar a rara ocorrência de um adenocarcinoma neuroendócrino misto (MANEC) no coto gástrico. RELATO DE CASO: É relatado o caso de uma mulher de 83 anos que apresentou um MANEC localmente agressivo 35 anos após uma gastrectomia à Billroth II devido a úlcera péptica. Foi submetida a ressecção e terapia adjuvante e foi seguida por 12 meses sem sinais de recorrência. CONCLUSÃO: Os MANECs constituem raro tipo de neoplasia gastrointestinal. Sua classificação, histopatologia, aspectos clínicos, tratamento e prognóstico são discutidos junto com uma breve revisão de literatura.

Pancreatogastroanastomosis en pancreatoduodenectomía: una alternativa segura de anastomosis al muñón pancreático / Pancreatogastroanastomosis in pancreatoduodenectomy: a sure alternative of anastomosis to the pancreatic stump

La pancreatogastroanastomosis (PG) es una de las alternativas en la reconstrucción del muñón pancreático luego de una pancreatoduodenectomía (PD). Descrita en 1946, sólo ha cobrado popularidad en los últimos 10 años. Pareciera que esta modalidad de reconstrucción pancreática se asocia con menor incidencia de filtración de la anastomosis y, con ello, menos morbi-mortalidad relacionada al procedimiento. En este trabajo se presentan los detalles técnicos involucrados en este procedimiento, los resultados clínicos obtenidos y su impacto en la actitud hacia la PD por parte de los cirujanos de nuestro servicio

Cáncer de Muñón Gástrico / Stomal cancer

Se revisan diferentes aspectos del problema que incluye el riesgo estimado post-cirugía gástrica, la relación del cáncer primario de muñón gástrico (CPMG) con el tipo de cirugía gástrica, la localización más frecuente, los aspectos histopatológicos, la patogenia, sintomatología y diagnóstico y la racionalización del tratamiento quirúrgico. Se concluye de esta revisión que no se conoce la prevalencia real del CPMG y el hecho de que la gran mayoría de las veces se diagnostica cuando el tumor está en fase avanzada

Diagnóstico preoperatorio por métodos de imagen de una apendicitis del muñón / Preoperative diagnostic imaging in stump appendicitis

La apendicitis del muñón es una entidad rara en la que a menudo el diagnóstico se retrasa y se lleva a cabo en el quirófano. El conocimiento de esta entidad hace que sea posible su diagnóstico preoperatorio por métodos de imagen, disminuyendo la morbilidad de la misma. Presentamos a una paciente con una apendicitis del muñón apendicular diagnosticada preoperatoriamente por medio de radiografía simple y tomografía computarizada abdominal

Cáncer de muñón gástrico: resultados del tratamiento quirúrgico / Gastric stump cancer: results of surgical treatment

Introducción. El pronóstico de cáncer de muñón gástrico, en general, es peor que el de cáncer gástrico primario. Métodos. Un total de 33 pacientes con cáncer de muñón tratados en nuestro servicio desde 1984 a 1999, 31 varones y 2 mujeres, con una edad media de 69,6 años. La primera intervención fue por úlcera gástrica en 14 casos, y duodenal o pilórica en 19. Presentaban gastrectomía Billroth II 22 pacientes y Billroth I 11 pacientes. El intervalo medio entre la primera operación y el diagnóstico del tumor fue de 30,6 años. Resultados. Fueron operados 27 pacientes; el índice de resecabilidad fue del 66,6 por ciento. Se realizaron 16 gastrectomías totales, 6 de ellas ampliadas y 2 casi totales. Predominó el adenocarcinoma tipo intestinal (22 casos); 4 pacientes presentaban tumores precoces (early) y en 13 (72,2 por ciento) existía afección de la serosa (pT3-pT4). La supervivencia actuarial global a los 5 años es del 22 por ciento, un 41,4 por ciento en los pacientes resecados (p < 0,001). Fue significativa la supervivencia de los casos resecados según el tamaño del tumor (p < 0,05).Conclusiones. En los pacientes gastrectomizados parece aconsejable el control endoscópico a partir de los 15 años para mejorar la resecabilidad y la supervivencia mediante un diagnóstico más precoz. La supervivencia obtenida en los casos tratados con gastrectomía total justifica este tratamiento quirúrgico agresivo. Hubo diferencias significativas en la supervivencia según el tamaño del tumor (AU)
