Perforation of gastric cancer - What should the surgeon do?

Case report: Radiography and computed tomography of tension pneumoperitoneum caused by gastric perforation in a dog

Tension pneumoperitoneum is characterized by excessive accumulation of gas in the peritoneal cavity, which leads to cardiorespiratory distress. We present the case of a 4-year-old female Labrador retriever who presented with a severe abdominal distension and panting. Radiography revealed a large volume of free gas in the peritoneal cavity with decreased serosal detail. After emergency needle decompression, ultrasound-guided aspiration of the peritoneal effusion helped confirm septic peritonitis. Computed tomography revealed a gastric mass measuring approximately 3.7 × 5.0 × 5.5 cm, which was suspected to have caused the gastric perforation. A large volume of free gas was present in the peritoneal cavity, causing compression and centralization of the abdominal organs. A low-attenuating cleft suggestive of perforation site near the gastric mass was also observed. Exploratory laparotomy confirmed gastric perforation of approximately 2.2 cm adjacent to the gastric mass. The patient was finally diagnosed with tension pneumoperitoneum caused by gastric perforation. The mass was resected with a 1-2-cm surgical margin, and imprinting cytology indicated gastric carcinoma. The patient was aggressively treated with fluid, analgesic, antithrombotic, and antibacterial therapy. However, the patient's condition continued to deteriorate, and euthanasia was performed at the owner's request. Our report is the first to describe the multimodal imaging features of a dog with tension pneumoperitoneum secondary to gastric perforation caused by gastric neoplasm.

An unusual cause of peritonitis: Perforation of a gastric carcinoma

Gastric carcinoma perforation is an uncommon consequence that is often missed during the preoperative stage. Perforation may occur at any stage of cancer, but it is more common in late stages. It can also happen early in the illness. Because of the spilled stomach contents, it produces an acute abdominal syndrome. The goal of treatment should be to strike a balance between the emergency situation of peritonitis and oncological surgical techniques. A case of stomach cancer perforation with typical imaging findings is presented.

The role of laparoscopic management in perforated gastric cancer

Purpose

Perforated gastric cancer is an extremely rare condition and usually presents in advanced stage with poor prognosis. Surgical strategies are still controversial regarding the extent to which complete resection or primary repair is performed and the application of laparoscopic techniques. We aim to determine the role of laparoscopic 2-stage approach in perforated gastric cancer.

Methods

Among 2,318 gastric cancers in Yeouido St. Mary's Hospital from January 1990 to December 2017, 20 patients with perforated gastric cancer were enrolled, and 5 patients underwent 2-stage gastrectomy consisting of primary closure on perforation followed by curative gastrectomy. Clinicopathological features, surgical outcomes, and survival analysis were evaluated.

Results

Two-stage approach for perforated gastric cancer was all performed by laparoscopic approach except 1 patient who needed paraaortic lymph node dissection (LND). Those were first treated on peritonitis with laparoscopic primary closure with or without Foley gastrostomy. Compared to 1-stage gastrectomy, more D2 LND was performed (60.0% vs. 100.0%, P = 0.260) and retrieved lymph nodes were significantly higher (median [range]: 17.0 [12.0–27.0] vs. 33.0 [26.5–43.5], P = 0.019]. Two patients of stage II and 3 patients of stage III were included in the 2-stage gastrectomy group. During the 38 months of median follow-up period, there were 8 and 1 recurrence among 1-stage and 2-stage gastrectomies, respectively. Except for 1 patient, 4 other 2-stage patients survived around 5 years without recurrence (5-year disease-free survival, 80%).

Conclusion

Laparoscopic 2-stage surgery for perforated gastric cancer is safe and might increase the curability of gastrectomy with extended LND.

Perforated gastric cancer: a critical appraisal

Gastric cancer perforation is a life-threatening condition that accounts for less than 5% of all gastric cancer patients and typically requires emergency surgery. However, preoperative diagnosis is difficult and management has a dual purpose: to treat peritonitis and to achieve a curative resection. The optimal surgical strategy is still unclear and prognosis remains poor. A search of the literature was performed using MEDLINE databases (Pubmed, EMBASE, Web of Science and Cochrane) using terms such as "perforated gastric cancer", "perforated gastric cancer and surgery", "perforated gastric tumour" and "gastric cancer perforated". Case reports, other reviews, non-english written papers and papers written before 2010 were excluded. Eight articles published between 2010 and 2020 matched the inclusion criteria for this review. Perforated gastric cancer was more prevalent in elderly males. Distal stomach was most frequently involved. Preoperative diagnosis was uncommon. Mortality rates ranged from 2 to 46%. Patients able to receive an R0 resection demonstrated better long-term survival compared with patients who had simple closure procedures. Laparoscopic procedure was mentioned only in one study. In an emergency situation, curative RO resection should always be offered in patients without multiple adverse factors. A surgical strategy using laparoscopic local repair as first step of surgery to resolve the peritonitis followed by a radical open or laparoscopic gastrectomy with lymphadenectomy could be considered. A balance between emergency and oncological needs should drive the surgical choice on a case by case basis.

Optimal treatment and complications of patients with the perforated upper gastrointestinal tract

PURPOSE

The perforation of the upper gastrointestinal tract is still associated with a high risk of complications and mortality. We aimed to evaluate the optimal treatment and post-treatment complications for this condition.

METHODS

This was a retrospective, single-center study conducted between 2010 and 2019. We analyzed 50 patients with intraperitoneal free air caused by peptic ulcer (44 cases) or cancer (six cases).

RESULTS

All patients initially received either conservative therapy (n = 7) or surgery (n = 43). The nonsurgically cured patients were significantly younger and had mild peritonitis and also had a shorter hospital stay. Two patients were converted to surgery due to worsening symptoms, and one of them was elderly and had a long perforation-to-treatment time. Regarding postoperative complications, patients with Grade II-V (n = 21) were significantly older and had a poorer physical status, longer perforation-to-surgery time, and higher preoperative CRP and lactate than those with Grade 0-I (n = 24). Multivariable analyses identified elevated preoperative lactate as an independent risk factor for postoperative complications. The patients with noncurative surgery for perforated advanced gastric cancer all died within 1 year after surgery.

CONCLUSIONS

Consideration should be given to the nonsurgical indications in elderly and delayed treatment patients and the postoperative outcomes of patients with preoperatively elevated lactate levels.

A Perforated Gastric Carcinoma: A Single-Center Experience

Objective

In this study, we aimed to describe clinicopathologic characteristics of the patients with a perforated gastric carcinoma, and to assess surgical approaches and possible factors affecting mortality and morbidity.

Material and Method

We retrospectively reviewed data of 18 patients who underwent emergent surgery for a perforated gastric carcinoma between January 2002 and December 2012. Data including surgical procedure, pathologic findings, complications, morbidity and mortality rates, and outcomes were evaluated.

Results

The mean age was 58 years. The most common tumor localization was antrum (55%), and 11 patients (61.1%) had Stage IV disease. Nine patients (50%) had a comorbid disease. Of the patients, primary suture + omentopexy was performed in 11 (61.1%) whereas total gastrectomy with D0 or D1 lymph node dissection in 5 (27.7%), subtotal gastrectomy with D0 lymph node dissection in 2 (11.1%), and 2-stage total gastrectomy with D2 lymph node dissection in 2 (11.1%). The complication rate was 50% with a mortality rate of 50%. Overall survival was 79 ± 97.89 days. Sepsis and the presence of comorbidities were found to increase early mortality (P = 0.00 and P = 0.028)

Conclusion

Our study results show that postoperative morbidity and mortality rates are still high in patients with a perforated gastric carcinoma. In stable patients, 1-step radical gastrectomy should be performed, while palliative surgery or 2-stage radical gastrectomy can be performed in patients with poor overall status and diffuse peritonitis. Early diagnosis and perforation management before the onset of diffuse peritonitis can decrease high mortality and morbidity rates.

An Overview of Gastroduodenal Perforation

Gastroduodenal perforation may be spontaneous or traumatic and the majority of spontaneous perforation is due to peptic ulcer disease. Improved medical management of peptic ulceration has reduced the incidence of perforation, but still remains a common cause of peritonitis. The classic sub-diaphragmatic air on chest x-ray may be absent and computed tomography scan is a more sensitive investigation in the stable patient. The management of perforated peptic ulcer disease is still a subject of debate. The majority of perforated peptic ulcers are caused by Helicobacter pylori, so definitive surgery is not usually required. Perforated peptic ulcer is an indication for operation in nearly all cases except when the patient is asymptomatic or unfit for surgery. However, non-operative management has a significant incidence of intra-abdominal abscesses and sepsis. Primary closure is achievable in traumatic perforation, but the management follows the Advanced Trauma Life Support (ATLS) principles.

Chemotherapy-induced necrotising tumour lysis and perforation of a huge gastric cancer simulating emphysematous pancreatitis

A 56-year-old man was diagnosed to have a huge gastric cancer extending from the lesser curvature of the stomach to the pancreas with multiple hepatic and peritoneal metastases. Two days after completing chemotherapy with cisplatin plus high dose leucovorin and fluorouracil, drastic necrotising tumour lysis led to gastric perforation and septic shock most likely due to bacterial peritonitis. The image of tumour lysis looked like an emphysematous pancreatitis. Afterwards, immunohistochemical study of the tumour specimen confirmed moderate positivity of dihydropyrimidine dehydrogenase and absence of Bcl-2 expression. The incomplete expression of dihydropyrimidine dehydrogenase and total deficiency of Bcl-2 are considered to be the main underlying causes of such extraordinary chemosensitivity and so severe a tumour lysis phenomenon. Pre-emptive intensive survey of possible biomarkers of chemosensitivity is thus highly recommended upon treating a massive gastric cancer.

Perforated Gastric Cancer: A Systematic Review

Background: Although gastric carcinoma is the fifth most commonly diagnosed cancer, optimal treatment of perforated cancer remains debated. Materials and Methods: The study was conducted according to the guidelines from the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) statement. An electronic systematic search was conducted using MEDLINE databases (PubMed, EMBASE, and Web of Science) by matching the terms "perforated gastric cancer," "gastric cancer perforated," "perforation AND gastric cancer," and "perforated gastric tumor." Results: Fifteen studies published between 1995 and 2018 and including 964 patients matched the inclusion criteria for this systematic review. There were 4 publications from Japan, 3 from Turkey, and 1 from China, Germany, Hong Kong, Italy, Nepal, Serbia, South Korea, and Taiwan, respectively. The sample size of the individual studies ranged from 8 to 514 patients. Perforated gastric carcinoma was rare and more prevalent in elderly males, preoperative diagnosis was uncommon, and the distal stomach was most frequently involved. Mortality was 11.4% and 1.9%, respectively, in one-stage versus two-stage gastrectomy (P = .010). Curative treatment by omental patch repair and staged gastrectomy yielded acceptable 5-year survival rates. There were no significant differences in the recurrence rate and pattern between perforated and nonperforated gastric cancer if a curative operation was performed. Use of laparoscopy was mentioned only in one study. Conclusions: Future studies should evaluate the role of laparoscopic surgery and clarify the indications for hyperthermic intraperitoneal chemotherapy and extensive peritoneal lavage protocols to decrease gastric cancer cell shed in the surgical field and increase long-term survival.

Urgent Surgery for Gastric Adenocarcinoma: A Study of the National Cancer Database

BACKGROUND

Gastric adenocarcinoma is a leading cause of cancer death worldwide and, in the United States, can present emergently with upper GI hemorrhage, obstruction, or perforation. No large studies have examined how urgent surgery affects patient outcomes. This study examines the outcomes of urgent versus elective surgery for gastric cancer.

MATERIALS AND METHODS

Patients with gastric adenocarcinoma from the National Cancer Database from 2004 to 2015 were examined retrospectively. Patients with metastatic disease or incomplete data were excluded. Urgent surgery was defined as definitive surgery within 3 d of diagnosis. Univariate and multivariate analysis of patient factors, surgical outcomes, and oncologic data was performed. P-values <0.05 were statistically significant.

RESULTS

Of 26,116 total patients, 2964 had urgent surgery and 23,468 had elective surgery. Urgent surgery patients were significantly older, were female, were nonwhite, had higher pathologic stage, and were treated at a low-volume center. Urgent surgery was associated with decreased quality lymph node harvest (odds ratio [OR] 0.68 95% confidence interval {CI} [0.62, 0.74]), increased positive surgical margin (OR 1.48, 95% CI [1.32, 1.65]), increased 30-d mortality (OR 1.38, 95% CI [1.16, 1.65]), increased 90-d mortality (OR 1.30, 95% CI [1.14, 1.49]), and decreased overall survival (hazard ratio 1.21, 95% CI [1.15, 1.27]).

CONCLUSIONS

Urgent surgery for gastric cancer is associated with significantly worse outcomes than elective surgery. Stable patients requiring urgent surgical resection for gastric cancer may benefit from referral to a high-volume center for resection by an experienced surgeon. Patients undergoing urgent resection for gastric cancer should be referred to surgical and medical oncologists to ensure they receive appropriate adjuvant therapy and surveillance.

Surgical outcome evaluation of perforated gastric cancer: from the aspects of both acute care surgery and surgical oncology

BACKGROUND

Perforated gastric cancer (PGC) is a rare condition of gastric cancer (GC). In this study, we sought to assess the outcome of PGC from the aspects of both acute care surgery and surgical oncology at a single institute, Chang Gung Memorial Hospital (CGMH).

METHODS

From 1997 to 2013, 6864 patients were diagnosed with GC and 2738 were diagnosed with gastroduodenal perforation at CGMH. In total, 29 patients with PGC were identified. Immediate surgical and long-term oncologic outcomes were evaluated after an appropriate matching process was performed.

RESULTS

The immediate surgical outcome of PGC, i.e., the hospital mortality rate within 30 d after surgery, did not significantly differ from that of non-cancer related gastroduodenal perforation. The long-term oncologic outcome, with matching by age, gender, year of surgery and AJCC 7th stage grouping, also did not significantly differ from that of GC without perforation.

CONCLUSIONS

Aggressive surgical treatment, including an initial emergency procedure for containing peritonitis and radical surgery for GC, may benefit PGC patients in terms of both the immediate and oncologic outcomes.
